The Diagnosis: Atypical Mycobacterial Infection

Punch biopsy specimens demonstrated necrotizing granulomatous inflammation in the dermis and subcutis (Figure). Special staining for microorganisms was negative. Tissue culture grew Mycobacterium avium-intracellulare (MAI). The patient began treatment with azithromycin, ethambutol, and rifabutin. Tissue susceptibilities later showed resistance to rifabutin and sensitivity to clarithromycin, moxifloxacin, and clofazimine. She subsequently was switched to azithromycin, clofazimine, and moxifloxacin with good response.

Mycobacterium avium-intracellulare is a slow-growing, nonchromogenic, atypical mycobacteria. Although ubiquitous, it tends to only cause serious infection in the setting of immunosuppression. Transmission usually is through the respiratory or gastrointestinal tract.¹ Skin infections with MAI are uncommon and usually are secondary to seeding from disseminated infection or from direct inoculation.²

The clinical presentations of primary cutaneous MAI are myriad, including an isolated red nodule, multiple ulcers, abscesses, draining sinuses, facial nodules, granulomatous plaques, and panniculitis.^2,3 Of 3 reported cases of primary cutaneous MAI in the form of sporotrichoid lesions, 2 involved patients with AIDS² and 1 involved a cardiac transplant recipient.⁴

Cutaneous MAI is typically diagnosed with skin biopsy and tissue culture. Tissue culture is critical for determining the specific mycobacterial species and antibiotic susceptibilities. Polymerase chain reaction has been utilized to rapidly diagnose cutaneous MAI infection from an acid-fast bacilli–positive tissue sample in which the tissue culture was negative.⁵

Recommended treatment protocols for MAI involve multidrug regimens because of the intrinsic resistance of MAI and the concern for development of resistance with monotherapy.² No definitive guidelines exist for treatment of primary cutaneous MAI infections. However, regimens for the treatment of pulmonary infection that also have been successfully utilized for cutaneous infection include a macrolide, ethambutol, and a rifamycin.⁶ Clinicians should be aware of MAI as a cause of primary cutaneous infections presenting as lymphocutaneous suppurative nodules and ulcerations.

Acne vulgaris predominantly occurs during puberty and can persist beyond 25 years of age, most commonly in women.^1,2 Although acne does not cause physical impairment, it can be associated with a considerable psychosocial burden including increased levels of anxiety, anger, depression, and frustration, which in turn can affect vocational and academic performance, quality of life (QOL), and self-esteem.³

Quality of life measures provide valuable insight into the debilitating effects of acne.¹ It has been suggested that acne patients may experience poor body image and low self-esteem as well as social isolation and constriction of activities.⁴ Self-esteem is a favorable and unfavorable attitude toward oneself.⁵ A marked emphasis has been placed on body image in society, fueled by external cues such as the media.^3,6 This study was carried out to assess QOL and self-esteem in acne patients.

Methods

This prospective, hospital-based, cross-sectional, case-control study was conducted at The Oxford Medical College, Hospital & Research Center (Bangalore, India), over a period of 3 months. One hundred consecutive acne cases (age range, 12–45 years) and 100 age- and gender-matched controls who did not have any skin disease provided consent and were included in the analysis. Guardians gave consent for individuals who were younger than 18 years. Exclusion criteria for cases included a medical disorder (eg, epilepsy, diabetes mellitus, hypertension) or medications that would likely interfere with acne assessment.

The cases and controls were administered a semistructured questionnaire to collect sociodemographic details. Acne was graded for the predominant lesions, QOL was assessed using the Cardiff Acne Disability Index (CADI) and World Health Organization Quality of Life–BREF (WHOQOL-BREF) scale, and self-esteem was measured using the Rosenberg self-esteem scale (RSES). The study was approved by the institutional review board.

Acne Grading

Acne was graded according to the predominant lesions using the following criteria: grade 1=comedones and occasional papules; grade 2=papules, comedones, and few pustules; grade 3=predominant pustules, nodules, and abscesses; and grade 4=mainly cysts, abscesses, and widespread scarring.¹

Quality of Life Assessment

The CADI questionnaire was used to assess the level of disability caused by acne.⁶ It is a 5-item questionnaire with scores ranging from 0 to 3 for a total maximum score of 15 and minimum score of 0. Total scores were classified as low (0–4), medium (5–9), and high (10–15).⁷

The WHOQOL-BREF is a self-reported questionnaire containing 26 items that make up the 4 domains of physical health (7 items), psychological health (6 items), social relationships (3 items), and environment (8 items); there also are 2 single questions regarding the overall perception of QOL and health. Questions were scored on aseries of 5-point scales with higher scores denoting better QOL.⁸

Self-esteem Assessment

The RSES uses a 5-point Likert scale from strongly agree to strongly disagree to rate a series of 10 statements. The total score ranges from 0 to 30. Scores less than 15 suggest low self-esteem, while scores of 15 and greater indicate high self-esteem.⁵

Statistical Analysis

Results were analyzed using descriptive and inferential statistical methods. A χ² test was used for categorical data, and a Student t test and an analysis of variance were used for continuous data.

Results

The study consisted of 100 cases and 100 controls. The mean age was 21 years. The majority of cases reported an age of onset of acne of 11 to 20 years (66%), were predominantly female (58%) from rural backgrounds, and had a family history of acne (68%). The majority of lesions ceased within 24 months (60%). The face was the most commonly involved area (80%) and papules were the most prevalent lesion type (62%).

Cases predominantly had grade 2 acne (46%), and there was medium to high impairment in QOL according to CADI scores.

The scores for all the domains of the WHOQOL-BREF as well as the total score were lower in cases compared to controls (Table). There was a statistically significant difference between the 2 groups in the psychological (P=.0402) and environment (P=.006) domains.

The RSES mean (SD) score was higher in controls (19.74 [4.23]) than in cases (15.72 [5.06]) and was statistically significant (P<.0001). Low self-esteem was noted in 38% of cases and 16% of controls, and high self-esteem was noted in 62% and 84%, respectively.

In reviewing the correlation between acne severity, CADI, WHOQOL-BREF, and RSES scores, we found a positive correlation between acne severity and CADI scores (R=0.51), which implies that as the severity of acne worsens, the QOL impairment increases. There was a negative correlation between acne severity, WHOQOL-BREF score (R=–0.13), and RSES score (R=–0.18), which showed that as the severity of acne increases, QOL and self-esteem decrease. We observed that as the grade of acne increases, there is a statistically significant impairment in the QOL according to CADI (P<.001), while there is a reduction in QOL and self-esteem according to WHOQOL-BREF and RSES, respectively (P>.05).

Comment

Patients are more likely to develop acne than any other skin disease in their lifetime. Only in recent years has the psychodermatologic literature begun to address the possibility of acne having a psychological and emotional impact.⁴ Although the cause-and-effect relationship between acne and psychological trauma has been debated for decades, only recently has the measurement focus shifted from psychological correlates (eg, personality) and emotional triggers (eg, stress) to the effect of acne on patients’ QOL and self-esteem. This shift occurred as validated instruments for measuring disability, QOL, and self-esteem, specifically in patients with skin diseases, became available.⁹

In our study, the age of onset of acne was 11 to 20 years and it affected predominantly females (58%), which is in concordance with other studies, as acne develops in adolescence and subsides in adulthood.^1,10 Acne is more common in females due to hormonal factors and use of cosmetics. We observed that the face (80%) was most frequently affected, followed by the back (14%) and chest (6%), which is similar to prior studies.^1,10 Because the face plays an important role in body image, the presence of facial lesions may be unacceptable for patients and therefore they may present more frequently to dermatologists.

In our study, 68% of cases and 22% of controls had a family history of acne. A similar correlation also was noted in other studies, which suggests acne has an inherited predisposition due to involvement of the cytochrome P450-1A1 gene, CYP1A1, and steroid 21-hydroxylase, P-450-c21.^1,11 We found 46% of cases had grade 2 acne and 36% had grade 1 acne, which was congruent with prior studies.^12,13 Patients with severe acne are more likely to seek medical intervention in hospitals.

In our study, 58% of the cases had medium to high impairment in QOL according to CADI scores. We noticed as the severity of acne increased there was severe impairment in QOL. Similar findings have been found in studies that used other scales to assess QOL.^1,6,9

In our study, 38% of cases and 16% of controls had low self-esteem, which was statistically significant (P<.0001). There was a negative correlation between the severity of acne and self-esteem. In a prior study of 240 professional college students, 53% had feelings of low self-esteem and 40% revealed they avoided social gatherings and interactions with the opposite sex because of their acne.¹⁴ In a questionnaire-based survey of 3775 students, it was observed that the presence of acne correlated with poor self-attitude in boys and poor self-worth in girls.³ We found patients with grade 1 acne had higher self-esteem as compared to other grades of acne. Similarly, a cross-sectional study by Uslu et al¹⁵ found a direct correlation between acne severity and lower self-esteem using the RSES questionnaire. Although acne may be viewed as a minor cosmetic issue, it can have a negative impact on self-esteem and interpersonal relationships. Many of the studies had not used a validated structured questionnaire to assess self-esteem and there is a paucity of literature in relation to acne and self-esteem.^3,16,17

According to the WHOQOL-BREF, the psychological domain was affected more in cases than in controls, which was a statistically significant difference. One study observed that patients experience immediate psychological consequences of acne such as reduced self-esteem, poor self-image, self-consciousness, and embarrassment.³ These effects are exacerbated by taunting, stigmatization, and perceptions of scrutiny and being judged, causing patients to avoid interaction and social situations. Similarly, Pruthi and Babu¹⁸ observed that acne had an impact on the psychosocial aspects of adult females using the Dermatology Life Quality Index and CADI.

Financial resources, health and social care accessibility, and opportunities for acquiring new information and skills were the factors that were considered in the environment domain of the WHOQOL-BREF.⁸ We noted that the environment domain scores were significantly lower in cases than in controls. The cases could have had a detrimental effect on the latest opportunities in occupational functioning due to acne, and as most of the population was from a rural area, they were having less favorable circumstances in acquiring new information about the management of acne.

There was no statistically significant difference between cases and controls in the social and physical domains of the WHOQOL-BREF, which suggests that these fields do not influence QOL. Similarly, patients in Sarawak, Malaysia, were least affected in the domain of social functioning, which was likely attributed to the upbringing of this population encouraging stoicism.¹⁹

In the current study, QOL impairment showed a positive correlation with acne severity according to CADI scores; however, there was no significant difference between WHOQOL-BREF score and acne grading, which suggests that QOL impairment does not depend on severity of acne alone. Physical, psychological, social, and environment domains play an important role in impaired QOL. Hence, by using the WHOQOL-BREF we can evaluate the actual domain that is adversely affected by acne and can be treated with a holistic approach. This point must be stressed in the training of medical faculty, as the treatment of acne should not be based on acne severity alone but also on the degree of QOL impairment.¹⁹

These results indicate that more data are required and there is a need to consider other variables that could play a role. This study was a hospital-based, cross-sectional study with a small sample group that cannot be generalized, which are limitations. Longitudinal follow-up of the cases before and after treatment was not done. The questionnaires helped us to detect psychosocial aspects but were insufficient to diagnose psychiatric comorbidity.

The strengths of this study include the use of a specific scale for the assessment of self-esteem. The usage of comprehensive (WHOQOL-BREF) and specific (CADI) scales to evaluate QOL has mutual advantage.

Conclusion

Acne vulgaris is a disease that can adversely affect an individual’s QOL and self-esteem. This study suggested the importance of screening for psychosocial problems in those who present for management of acne. It is important for dermatologists to be cautious about psychological problems in acne patients and be aware of the importance of basic psychosomatic treatment in conjunction with medical treatment in the management of acne.

Acne vulgaris predominantly occurs during puberty and can persist beyond 25 years of age, most commonly in women.^1,2 Although acne does not cause physical impairment, it can be associated with a considerable psychosocial burden including increased levels of anxiety, anger, depression, and frustration, which in turn can affect vocational and academic performance, quality of life (QOL), and self-esteem.³

It is important for dermatologists to be cautious about psychological problems in acne patients and be aware of the importance of basic psychosomatic treatment in conjunction with medical treatment in the management of acne.

Acne vulgaris predominantly occurs during puberty and can persist beyond 25 years of age, most commonly in women.^1,2 Although acne does not cause physical impairment, it can be associated with a considerable psychosocial burden including increased levels of anxiety, anger, depression, and frustration, which in turn can affect vocational and academic performance, quality of life (QOL), and self-esteem.³

Quality of life measures provide valuable insight into the debilitating effects of acne.¹ It has been suggested that acne patients may experience poor body image and low self-esteem as well as social isolation and constriction of activities.⁴ Self-esteem is a favorable and unfavorable attitude toward oneself.⁵ A marked emphasis has been placed on body image in society, fueled by external cues such as the media.^3,6 This study was carried out to assess QOL and self-esteem in acne patients.

Methods

This prospective, hospital-based, cross-sectional, case-control study was conducted at The Oxford Medical College, Hospital & Research Center (Bangalore, India), over a period of 3 months. One hundred consecutive acne cases (age range, 12–45 years) and 100 age- and gender-matched controls who did not have any skin disease provided consent and were included in the analysis. Guardians gave consent for individuals who were younger than 18 years. Exclusion criteria for cases included a medical disorder (eg, epilepsy, diabetes mellitus, hypertension) or medications that would likely interfere with acne assessment.

The cases and controls were administered a semistructured questionnaire to collect sociodemographic details. Acne was graded for the predominant lesions, QOL was assessed using the Cardiff Acne Disability Index (CADI) and World Health Organization Quality of Life–BREF (WHOQOL-BREF) scale, and self-esteem was measured using the Rosenberg self-esteem scale (RSES). The study was approved by the institutional review board.

Acne Grading

Acne was graded according to the predominant lesions using the following criteria: grade 1=comedones and occasional papules; grade 2=papules, comedones, and few pustules; grade 3=predominant pustules, nodules, and abscesses; and grade 4=mainly cysts, abscesses, and widespread scarring.¹

Quality of Life Assessment

The CADI questionnaire was used to assess the level of disability caused by acne.⁶ It is a 5-item questionnaire with scores ranging from 0 to 3 for a total maximum score of 15 and minimum score of 0. Total scores were classified as low (0–4), medium (5–9), and high (10–15).⁷

The WHOQOL-BREF is a self-reported questionnaire containing 26 items that make up the 4 domains of physical health (7 items), psychological health (6 items), social relationships (3 items), and environment (8 items); there also are 2 single questions regarding the overall perception of QOL and health. Questions were scored on aseries of 5-point scales with higher scores denoting better QOL.⁸

Self-esteem Assessment

The RSES uses a 5-point Likert scale from strongly agree to strongly disagree to rate a series of 10 statements. The total score ranges from 0 to 30. Scores less than 15 suggest low self-esteem, while scores of 15 and greater indicate high self-esteem.⁵

Statistical Analysis

Results were analyzed using descriptive and inferential statistical methods. A χ² test was used for categorical data, and a Student t test and an analysis of variance were used for continuous data.

Results

The study consisted of 100 cases and 100 controls. The mean age was 21 years. The majority of cases reported an age of onset of acne of 11 to 20 years (66%), were predominantly female (58%) from rural backgrounds, and had a family history of acne (68%). The majority of lesions ceased within 24 months (60%). The face was the most commonly involved area (80%) and papules were the most prevalent lesion type (62%).

Cases predominantly had grade 2 acne (46%), and there was medium to high impairment in QOL according to CADI scores.

The scores for all the domains of the WHOQOL-BREF as well as the total score were lower in cases compared to controls (Table). There was a statistically significant difference between the 2 groups in the psychological (P=.0402) and environment (P=.006) domains.

The RSES mean (SD) score was higher in controls (19.74 [4.23]) than in cases (15.72 [5.06]) and was statistically significant (P<.0001). Low self-esteem was noted in 38% of cases and 16% of controls, and high self-esteem was noted in 62% and 84%, respectively.

In reviewing the correlation between acne severity, CADI, WHOQOL-BREF, and RSES scores, we found a positive correlation between acne severity and CADI scores (R=0.51), which implies that as the severity of acne worsens, the QOL impairment increases. There was a negative correlation between acne severity, WHOQOL-BREF score (R=–0.13), and RSES score (R=–0.18), which showed that as the severity of acne increases, QOL and self-esteem decrease. We observed that as the grade of acne increases, there is a statistically significant impairment in the QOL according to CADI (P<.001), while there is a reduction in QOL and self-esteem according to WHOQOL-BREF and RSES, respectively (P>.05).

Comment

Patients are more likely to develop acne than any other skin disease in their lifetime. Only in recent years has the psychodermatologic literature begun to address the possibility of acne having a psychological and emotional impact.⁴ Although the cause-and-effect relationship between acne and psychological trauma has been debated for decades, only recently has the measurement focus shifted from psychological correlates (eg, personality) and emotional triggers (eg, stress) to the effect of acne on patients’ QOL and self-esteem. This shift occurred as validated instruments for measuring disability, QOL, and self-esteem, specifically in patients with skin diseases, became available.⁹

In our study, the age of onset of acne was 11 to 20 years and it affected predominantly females (58%), which is in concordance with other studies, as acne develops in adolescence and subsides in adulthood.^1,10 Acne is more common in females due to hormonal factors and use of cosmetics. We observed that the face (80%) was most frequently affected, followed by the back (14%) and chest (6%), which is similar to prior studies.^1,10 Because the face plays an important role in body image, the presence of facial lesions may be unacceptable for patients and therefore they may present more frequently to dermatologists.

In our study, 68% of cases and 22% of controls had a family history of acne. A similar correlation also was noted in other studies, which suggests acne has an inherited predisposition due to involvement of the cytochrome P450-1A1 gene, CYP1A1, and steroid 21-hydroxylase, P-450-c21.^1,11 We found 46% of cases had grade 2 acne and 36% had grade 1 acne, which was congruent with prior studies.^12,13 Patients with severe acne are more likely to seek medical intervention in hospitals.

In our study, 58% of the cases had medium to high impairment in QOL according to CADI scores. We noticed as the severity of acne increased there was severe impairment in QOL. Similar findings have been found in studies that used other scales to assess QOL.^1,6,9

In our study, 38% of cases and 16% of controls had low self-esteem, which was statistically significant (P<.0001). There was a negative correlation between the severity of acne and self-esteem. In a prior study of 240 professional college students, 53% had feelings of low self-esteem and 40% revealed they avoided social gatherings and interactions with the opposite sex because of their acne.¹⁴ In a questionnaire-based survey of 3775 students, it was observed that the presence of acne correlated with poor self-attitude in boys and poor self-worth in girls.³ We found patients with grade 1 acne had higher self-esteem as compared to other grades of acne. Similarly, a cross-sectional study by Uslu et al¹⁵ found a direct correlation between acne severity and lower self-esteem using the RSES questionnaire. Although acne may be viewed as a minor cosmetic issue, it can have a negative impact on self-esteem and interpersonal relationships. Many of the studies had not used a validated structured questionnaire to assess self-esteem and there is a paucity of literature in relation to acne and self-esteem.^3,16,17

According to the WHOQOL-BREF, the psychological domain was affected more in cases than in controls, which was a statistically significant difference. One study observed that patients experience immediate psychological consequences of acne such as reduced self-esteem, poor self-image, self-consciousness, and embarrassment.³ These effects are exacerbated by taunting, stigmatization, and perceptions of scrutiny and being judged, causing patients to avoid interaction and social situations. Similarly, Pruthi and Babu¹⁸ observed that acne had an impact on the psychosocial aspects of adult females using the Dermatology Life Quality Index and CADI.

Financial resources, health and social care accessibility, and opportunities for acquiring new information and skills were the factors that were considered in the environment domain of the WHOQOL-BREF.⁸ We noted that the environment domain scores were significantly lower in cases than in controls. The cases could have had a detrimental effect on the latest opportunities in occupational functioning due to acne, and as most of the population was from a rural area, they were having less favorable circumstances in acquiring new information about the management of acne.

There was no statistically significant difference between cases and controls in the social and physical domains of the WHOQOL-BREF, which suggests that these fields do not influence QOL. Similarly, patients in Sarawak, Malaysia, were least affected in the domain of social functioning, which was likely attributed to the upbringing of this population encouraging stoicism.¹⁹

In the current study, QOL impairment showed a positive correlation with acne severity according to CADI scores; however, there was no significant difference between WHOQOL-BREF score and acne grading, which suggests that QOL impairment does not depend on severity of acne alone. Physical, psychological, social, and environment domains play an important role in impaired QOL. Hence, by using the WHOQOL-BREF we can evaluate the actual domain that is adversely affected by acne and can be treated with a holistic approach. This point must be stressed in the training of medical faculty, as the treatment of acne should not be based on acne severity alone but also on the degree of QOL impairment.¹⁹

These results indicate that more data are required and there is a need to consider other variables that could play a role. This study was a hospital-based, cross-sectional study with a small sample group that cannot be generalized, which are limitations. Longitudinal follow-up of the cases before and after treatment was not done. The questionnaires helped us to detect psychosocial aspects but were insufficient to diagnose psychiatric comorbidity.

The strengths of this study include the use of a specific scale for the assessment of self-esteem. The usage of comprehensive (WHOQOL-BREF) and specific (CADI) scales to evaluate QOL has mutual advantage.

Conclusion

Acne vulgaris is a disease that can adversely affect an individual’s QOL and self-esteem. This study suggested the importance of screening for psychosocial problems in those who present for management of acne. It is important for dermatologists to be cautious about psychological problems in acne patients and be aware of the importance of basic psychosomatic treatment in conjunction with medical treatment in the management of acne.

Patients with chronic hepatitis B who are aged under 35 years or do not see the same clinician consistently are more likely to not take their antiviral medication, finds the largest study of its kind to date.

According to the authors of the research led by Nicole Allard, PhD, from the WHO collaborative Centre for Viral Hepatitis and the Peter Doherty Institute for Infection and Immunity in Melbourne, their findings illustrate the need for clinicians to reinforce the importance of medication adherence at each patient consultation.

Furthermore, “providing more flexible and convenient care arrangements, reminder systems, and working with the individual to maximize medication adherence should be a routine part of clinical practice,” they wrote in their paper published in the Journal of Viral Hepatitis. Previous research had shown that adherence to antiviral therapy in the treatment of hepatitis B was associated with improved patient outcomes. Suboptimal adherence could lead to antiviral resistance or antiviral breakthrough, potentially leading to liver cirrhosis and liver cancer.

Understanding poor adherence in clinical settings, together with the factors associated with lower adherence, was important in informing efforts for promoting adherence, the research team said (J Viral Hepat. 2016. doi: 10.1111/jvh.12582).

In their retrospective study they assessed the pharmacy records of 1,026 patients who were dispensed antiviral therapy for hepatitis B across four Australian public hospital outpatient clinics between 2010 and 2013.

They discovered that one in five patients were “nonadherent” to therapy based on a medication possession ratio of less than 0.90 – a cutoff shown in previous studies to be correlated with virologic breakthrough.

One significant factor that affected adherence to medication was being aged under 35 years (P = .002), the research team reported.

This finding was similar to other studies of chronic diseases that had shown younger patients were at a higher risk of nonadherence, the authors noted.

“Recognition of the challenges faced by a younger person regularly taking medication at a time in their lives when they feel well is important,” they wrote.

Poor adherence was also associated with seeing multiple clinicians over shorter periods of time.

“While hospitals accommodate trainees and staffing changes occur regularly, seeking to maximize the consistency of clinical care delivery may be an important strategy to support better adherence and optimizing care for individuals,” they said.

Factors such as variations in the amount of medication, duration of treatment, sex, and cultural background did not affect adherence to medication.

“Adherence is a dynamic process and needs to be addressed regularly in a nonjudgmental way working with individuals towards improved health,” they concluded.

The incidence of skin cancer, along with its effects on patients and the economy, has continued to increase and therefore requires particular attention from dermatologists. UV light has been shown to be of etiopathologic importance in the development of various types of skin cancer.^1-3 Studies have shown that there is a direct correlation between the incidence of skin cancer and average annual amounts of UV radiation exposure.³ Accordingly, in 2009 the International Agency for Research on Cancer classified UV light as carcinogenic to humans.⁴ Therefore, the general public must be made aware of the danger of exposure to UV radiation.

In Australia, government initiatives to educate the population on causes of skin cancer development and its relationship to UV radiation have already caused the public to change their way of thinking and to deal with sunlight in a conscious and responsible manner.⁵ A large proportion of the Australian population with light skin is at a particularly high risk for developing skin cancer due to intense exposure to UV radiation. Numerous campaigns in Germany and other countries have attempted to sensitize the public to this issue by emphasizing a reduction in UV exposure (primary prevention) or highlighting the importance of early diagnosis (secondary prevention).^6,7

For a good prognosis, it is crucial that skin cancer, particularly melanoma, is discovered at an early or precancerous stage.⁸ For this reason, self-examination of the skin and skin cancer screening are important factors that can contribute to ensuring early and curative treatment.^9-11 Since July 1, 2008, skin cancer screenings have been included in the preventative health care program by statutory health insurance providers in Germany. As part of this program, the cost of screening once every 2 years for individuals 35 years and older is covered by statutory health insurance.¹² Several studies have shown a decline in the melanoma mortality rate since the introduction of skin cancer screening programs in Germany.^11,13,14

Employee skin cancer screening programs are an important method of examining high numbers of individuals quickly and effectively. These programs have been carried out in Germany and other countries.^15,16 Studies have shown that skin cancer screening carried out selectively on defined groups can be an effective form of secondary prevention, particularly for those who work outdoors.¹⁷

An employee skin cancer screening program was carried out as part of this study. The findings are interpreted and discussed in relation to other employee screening programs that have been reported as well as those introduced by statutory health insurance providers in Germany. The aim of this study was to determine the importance and effectiveness of employee skin cancer screening programs and the role they play in secondary prevention of skin cancer.

Methods

Study Population

Employees of a technical company in Bavaria, Germany, were offered a skin cancer screening program by the employer’s occupational health service and health insurance provider in collaboration with the Department of Dermatology at the University Hospital Erlangen (Erlangen, Germany). Skin examinations were performed exclusively by 5 trained dermatologists. Only direct employees of the company at 3 of its locations in the Erlangen area were eligible to participate. The total number of employees varied by location (1072–5126 employees). The majority of employees had a university education or had completed technical training. Family members and other individuals who were not members of the company were excluded. There were no further inclusion or exclusion criteria. Over a period of 13 days, 783 of 7823 total employees (10.0%) were examined and included in the study. The study was approved by the Responsible Ethics Commission of the Faculty of Medicine at Friedrich-Alexander-University Erlangen-Nürnberg, Germany.

Study Design

Employees signed a consent form for participation in the study and completed a standardized questionnaire. The questionnaire was based on surveys used in a prior study¹⁸ and collected information on current and prior skin lesions, prior dermatological screening, personal and family history of skin tumors, frequency of UV exposure, and type of UV protection used. For the question on measures taken for protection from UV radiation, possible answers included with sunscreen cream, with suitable sun-protective clothing, and by staying in the shade, or no measures were taken. In contrast to the other questions, multiple answers were accepted for this question. Answering no automatically excluded other possible answers. Participants also were asked to assess their own Fitzpatrick skin type¹⁹; the questionnaire included explanations of each skin type (I–IV).

The participants were then called in for examination by the dermatologist at 15-minute intervals. All clothing was removed and the skin was examined. Dermatoscopes were used for closer examination of suspicious skin lesions. The clinical results of the examinations were recorded on a standardized form.

An estimation of the number of melanocytic nevi—≤20, 21–49, or ≥50—was recorded for each patient. Suspicious skin lesions were assigned to one of the following categories: nevus requiring future checkup (Nc), nevus requiring excision (Ne), suspected malignant melanoma (MM), suspected squamous cell carcinoma, suspected basal cell carcinoma (BCC), suspected other skin tumor, and precancerous lesion. Fitzpatrick skin type also was assessed for all participants and recorded by the dermatologist carrying out the examination. Each participant was assigned to a risk group—low, moderate, or high risk—based on their individual risk for developing a skin tumor. Factors that were considered when determining participants’ risk for developing skin cancer included Fitzpatrick skin type, number of melanocytic nevi, personal and family history, leisure activities, UV protection used, and current clinical diagnosis of skin lesions.

After the skin examination, participants were informed of recommended treatment but were not given any additional dermatologic advice. Participants could arrange an appointment at the Department of Dermatology, University Hospital Erlangen, for the excision and histological analysis of the skin lesions. All recorded data were collected in a computerized spreadsheet program. When evaluating the questionnaires, questions that were not answered or were answered incorrectly (participant chose more than 1 answer) were ignored.

Statistical Analysis

Statistical analysis was carried out using SPSS software version 16.0. The majority of the data were nominal or ordinal. Metric data were checked for normal distribution using the Shapiro-Wilk test before carrying out parametric tests. Statistical tests were carried out using the χ² test and the t test for independent samples. Non-nominal distributed data were checked using the Mann-Whitney U test. P<.05 was considered statistically significant in the exploratory data analysis.

Results

Of 783 employees included in the study, 288 (36.8%) were female and 495 (63.2%) were male (Table 1). In comparison with the total workforce, a significantly higher proportion of women than men took part in the cross-sectional study (P<.01). The average age (SD) was 42.3 (9.5) years (range, 18–64 years). Female participants (average age [SD], 39.8 [10.2] years) were significantly younger than male participants (average age [SD], 43.8 [8.8] years; P<.01). Forty-one percent of participants had a prior skin cancer screening. One percent of participants had a personal history of skin cancer, with 1 participant reporting a history of MM; 6.5% had a family history of skin cancer, of which 39.2% had a family history of MM.

The results of the clinical examinations showed that 43.8% of participants had 20 or fewer melanocytic nevi, 43.4% had 21 to 49 melanocytic nevi, and 12.8% had 50 or more melanocytic nevi. Significantly more women than men had 20 or fewer melanocytic nevi (P<.05).

Approximately 92% of participants assessed themselves as having Fitzpatrick skin types II (35.2%) or III (56.7%), while only approximately 3.6% and 4.5% assessed themselves as having skin types I and IV, respectively. The results of the Fitzpatrick skin type assessments made by dermatologists were similar: 96.9% of participants were assessed as having Fitzpatrick skin types II (43.0%) and III (53.8%); approximately 1.9% and 1.3% were assessed as having Fitzpatrick skin types I and IV, respectively. Results showed that 80.2% of all participants assessed their skin type in the same way as the dermatologist; 13.5% assessed their skin type as darker and 6.3% (49/783) assessed it as lighter. A quantitative analysis of Fitzpatrick skin type and sex showed that significantly more male participants than female participants assessed their Fitzpatrick skin type darker than their actual skin type (P<.01).

Overall, 47.6% of participants reported having had sunburn rarely in the past, while 36.9% and 14.0% had experienced sunburn once per year and several times per year, respectively. Approximately 1.4% of participants reported never having a sunburn. More of the male participants made use of comprehensive sun protection using all methods listed (34.5%; P<.05) or a combination of sunscreen and sun-protective clothing (14.9%; P<.01) than the female participants who relied more frequently on sunscreen alone (29.5%; P<.01) or a combination of sunscreen and staying in the shade (29.5%; P<.01)

In general it was clear that sunscreen, either alone or in combination with other sun-protection methods, was used most frequently (88.0%); 58.0% protected themselves by staying in the shade, while 48.0% used suitable sun-protective clothing. Only 3.6% of participants did not protect themselves using any of the suggested methods.

A total of 661 categorized skin lesions were found in 377 participants. Of these lesions, 491 were Nc and 121 were Ne. Twenty-four of the skin lesions were suspected precancerous lesions, 13 were suspected BCC, 2 were suspected MM, and 10 were suspected other skin tumor (Table 2). Overall, male participants who were diagnosed with at least 1 skin lesion (average age, 44.0 years) were significantly older than the women (average age, 39.3 years)(P<.01). Similar findings were observed in participants with at least 1 Nc (men, 43.3 years; women, 38.7 years; P<.01) and at least 1 Ne (men, 44.2 years; women, 38.0 years; P<.05). With regard to the individual risk for developing skin cancer, 32.6% of participants were considered to be at low risk, 64.9% were at moderate risk, and 2.6% were at high risk.

Approximately 61.5% of 377 participants who were diagnosed with at least 1 categorized skin lesion were advised to have a specific skin lesion checked by a dermatologist or to have a full examination for skin cancer once every 12 months. Furthermore, 22.5% were advised to follow-up biannually and 11.7% were advised to follow-up once every 2 years. Of the remaining participants who were advised to have follow-ups, 0.3% were advised to have a skin examination once every 3 months after having had MM, and 4.0% were advised to have follow-up once every 18 months. Overall, follow-up was recommended within 1 year in 84.4% of cases and within 1 to 2 years in 15.6% (Table 3).

Subsequent histological analysis of the excised tissue resulted in a diagnosis of only 21 clinically significant skin conditions. One case of Bowen disease and 1 case of BCC was confirmed. Histological analysis identified the remaining 19 excised skin lesions, which included the 2 suspected MMs, as dysplastic nevi.

Comment

The aim of this cross-sectional study was to examine the importance and effectiveness of employee skin cancer screening programs. In comparison with the total workforce, significantly more women took part than men. Female participants were significantly younger than male participants, which mirrors the findings of prior studies showing that screening programs reach women more frequently than men and that women who participate in screenings are also younger on average in comparison to men.^7-13 Men and older individuals usually are underrepresented.^7,13 The average age of participants in our study was 42.3 years, which is lower than in the SCREEN (Skin Cancer Research to Provide Evidence for Effectiveness of Screening in Northern Germany) study (average age, 49.7 years).¹³ The average age in our study also is likely to be lower than patients who undergo skin cancer screenings offered by statutory health insurance providers in Germany, which has a minimum age restriction of 35 years; however, it is comparable to the average age of participants in other employee screening programs and therefore represents the average age of individuals employed in Germany.^15,16

The employee skin cancer screening program in this study generated a high level of interest, indicated by the fact that all available appointments had been booked just 36 hours after the screening was announced. Furthermore, there was a waiting list of approximately 300 employees who were not able to undergo a skin examination. For logistical reasons, the number of participants was limited to 10% of the workforce. The high level of interest is an indication of increased awareness of the importance of recognizing skin tumors early and the associated need for information as well as the need to undergo screening for skin cancer as a precaution. This observation also can be made with regard to the skin cancer screening introduced by statutory health insurance providers in Germany. Studies published by Augustin et al²⁰ and Kornek et al^21,22 confirm that skin cancer screenings have gained wide acceptance in Germany because they were introduced by statutory health insurance providers in 2008. The number of skin cancer screenings carried out by dermatologists in Germany also is increasing.^20-22 Although approximately 19% of those eligible to participate took part in the SCREEN pilot project,¹³ approximately 31% of individuals who were eligible to participate took part in skin cancer screenings offered by statutory health insurance providers in Germany in 2012, and the percentage is rising.²³ Two important factors affecting the high level of interest in the employee screening program used in our study were undoubtedly the advantages of the examination taking place during working hours and being held on the occupational health services’ premises in the workplace, which helped participants avoid the cost of travel and wait times associated with visiting a medical practice.

Of 783 participants included in this study, 377 displayed at least 1 categorized skin lesion; the majority were suspicious melanocytic nevi. This high incidence rate suggested that regular skin cancer screenings are useful, as it has been shown that there is a correlation between higher numbers of melanocytic nevi and increased risk for developing melanoma.²⁴

In a study by Winkler et al,²⁵ a skin cancer screening of 1658 bank and insurance employees found that 33.8% of those examined displayed at least 1 atypical melanocytic nevus and 27.2% displayed more than 50 melanocytic nevi (compared to 12.8% with ≥50 melanocytic nevi in the current study). The risk for developing skin cancer was classified as intermediate or high in 54.5% (compared to 67.5% at moderate or high risk in the current study).²⁵ Therefore, the rate of suspicious skin lesions was lower in the population of the study by Winkler et al²⁵ in comparison to the population of the current study. As the overall number of melanocytic nevi and the individual risk for skin cancer, however, was underestimated by the majority of the bank and insurance employees,²⁵ employee skin cancer screening programs can be used as a potentially effective tool to make employees aware of the issue and sensitizing them to it. Employee screening in addition to a final diagnosis can contribute to ensuring suitable treatment is started. For example, in the large-scale employee screening published by Schaefer et al¹⁵ and Augustin et al,¹⁶ 48,665 and 90,880 employees, respectively, were screened for inflammatory and noninflammatory skin diseases, and 19% and 27% of participants, respectively, were diagnosed with skin lesions that required treatment.

Participants in the current study were given no further treatment or advice. Recommendations were made that participants monitor suspicious skin lesions or have them removed. With regard to future screening, 84.4% of participants with at least 1 categorized skin lesion were advised to have a regular follow-up within 1 year, while 15.6% were advised to follow-up within 1 to 2 years. Therefore, a period of 2 years before the next checkup, the period between screenings offered by statutory health insurance providers in Germany,¹² was considered too long for the majority of participants, according to the dermatologists involved with our study.

Conclusion

The high rate of suspicious skin lesions diagnosed demonstrated the effectiveness of skin cancer screenings organized in the workplace, which should be recommended for all employees, not only those who are at high risk for developing skin cancer due to the nature of their work, such as those who work outdoors. It should be noted that the study group examined in the current study was a homogeneous group of employees of a technical company only and is therefore relatively selective. Nevertheless, despite the comparatively selective and young participant group, these examinations provide evidence of the importance of skin cancer screening programs for a wider population.

The incidence of skin cancer, along with its effects on patients and the economy, has continued to increase and therefore requires particular attention from dermatologists. UV light has been shown to be of etiopathologic importance in the development of various types of skin cancer.^1-3 Studies have shown that there is a direct correlation between the incidence of skin cancer and average annual amounts of UV radiation exposure.³ Accordingly, in 2009 the International Agency for Research on Cancer classified UV light as carcinogenic to humans.⁴ Therefore, the general public must be made aware of the danger of exposure to UV radiation.

In Australia, government initiatives to educate the population on causes of skin cancer development and its relationship to UV radiation have already caused the public to change their way of thinking and to deal with sunlight in a conscious and responsible manner.⁵ A large proportion of the Australian population with light skin is at a particularly high risk for developing skin cancer due to intense exposure to UV radiation. Numerous campaigns in Germany and other countries have attempted to sensitize the public to this issue by emphasizing a reduction in UV exposure (primary prevention) or highlighting the importance of early diagnosis (secondary prevention).^6,7

For a good prognosis, it is crucial that skin cancer, particularly melanoma, is discovered at an early or precancerous stage.⁸ For this reason, self-examination of the skin and skin cancer screening are important factors that can contribute to ensuring early and curative treatment.^9-11 Since July 1, 2008, skin cancer screenings have been included in the preventative health care program by statutory health insurance providers in Germany. As part of this program, the cost of screening once every 2 years for individuals 35 years and older is covered by statutory health insurance.¹² Several studies have shown a decline in the melanoma mortality rate since the introduction of skin cancer screening programs in Germany.^11,13,14

Employee skin cancer screening programs are an important method of examining high numbers of individuals quickly and effectively. These programs have been carried out in Germany and other countries.^15,16 Studies have shown that skin cancer screening carried out selectively on defined groups can be an effective form of secondary prevention, particularly for those who work outdoors.¹⁷

An employee skin cancer screening program was carried out as part of this study. The findings are interpreted and discussed in relation to other employee screening programs that have been reported as well as those introduced by statutory health insurance providers in Germany. The aim of this study was to determine the importance and effectiveness of employee skin cancer screening programs and the role they play in secondary prevention of skin cancer.

Methods

Study Population

Employees of a technical company in Bavaria, Germany, were offered a skin cancer screening program by the employer’s occupational health service and health insurance provider in collaboration with the Department of Dermatology at the University Hospital Erlangen (Erlangen, Germany). Skin examinations were performed exclusively by 5 trained dermatologists. Only direct employees of the company at 3 of its locations in the Erlangen area were eligible to participate. The total number of employees varied by location (1072–5126 employees). The majority of employees had a university education or had completed technical training. Family members and other individuals who were not members of the company were excluded. There were no further inclusion or exclusion criteria. Over a period of 13 days, 783 of 7823 total employees (10.0%) were examined and included in the study. The study was approved by the Responsible Ethics Commission of the Faculty of Medicine at Friedrich-Alexander-University Erlangen-Nürnberg, Germany.

Study Design

Employees signed a consent form for participation in the study and completed a standardized questionnaire. The questionnaire was based on surveys used in a prior study¹⁸ and collected information on current and prior skin lesions, prior dermatological screening, personal and family history of skin tumors, frequency of UV exposure, and type of UV protection used. For the question on measures taken for protection from UV radiation, possible answers included with sunscreen cream, with suitable sun-protective clothing, and by staying in the shade, or no measures were taken. In contrast to the other questions, multiple answers were accepted for this question. Answering no automatically excluded other possible answers. Participants also were asked to assess their own Fitzpatrick skin type¹⁹; the questionnaire included explanations of each skin type (I–IV).

The participants were then called in for examination by the dermatologist at 15-minute intervals. All clothing was removed and the skin was examined. Dermatoscopes were used for closer examination of suspicious skin lesions. The clinical results of the examinations were recorded on a standardized form.

An estimation of the number of melanocytic nevi—≤20, 21–49, or ≥50—was recorded for each patient. Suspicious skin lesions were assigned to one of the following categories: nevus requiring future checkup (Nc), nevus requiring excision (Ne), suspected malignant melanoma (MM), suspected squamous cell carcinoma, suspected basal cell carcinoma (BCC), suspected other skin tumor, and precancerous lesion. Fitzpatrick skin type also was assessed for all participants and recorded by the dermatologist carrying out the examination. Each participant was assigned to a risk group—low, moderate, or high risk—based on their individual risk for developing a skin tumor. Factors that were considered when determining participants’ risk for developing skin cancer included Fitzpatrick skin type, number of melanocytic nevi, personal and family history, leisure activities, UV protection used, and current clinical diagnosis of skin lesions.

After the skin examination, participants were informed of recommended treatment but were not given any additional dermatologic advice. Participants could arrange an appointment at the Department of Dermatology, University Hospital Erlangen, for the excision and histological analysis of the skin lesions. All recorded data were collected in a computerized spreadsheet program. When evaluating the questionnaires, questions that were not answered or were answered incorrectly (participant chose more than 1 answer) were ignored.

Statistical Analysis

Statistical analysis was carried out using SPSS software version 16.0. The majority of the data were nominal or ordinal. Metric data were checked for normal distribution using the Shapiro-Wilk test before carrying out parametric tests. Statistical tests were carried out using the χ² test and the t test for independent samples. Non-nominal distributed data were checked using the Mann-Whitney U test. P<.05 was considered statistically significant in the exploratory data analysis.

Results

Of 783 employees included in the study, 288 (36.8%) were female and 495 (63.2%) were male (Table 1). In comparison with the total workforce, a significantly higher proportion of women than men took part in the cross-sectional study (P<.01). The average age (SD) was 42.3 (9.5) years (range, 18–64 years). Female participants (average age [SD], 39.8 [10.2] years) were significantly younger than male participants (average age [SD], 43.8 [8.8] years; P<.01). Forty-one percent of participants had a prior skin cancer screening. One percent of participants had a personal history of skin cancer, with 1 participant reporting a history of MM; 6.5% had a family history of skin cancer, of which 39.2% had a family history of MM.

The results of the clinical examinations showed that 43.8% of participants had 20 or fewer melanocytic nevi, 43.4% had 21 to 49 melanocytic nevi, and 12.8% had 50 or more melanocytic nevi. Significantly more women than men had 20 or fewer melanocytic nevi (P<.05).

Approximately 92% of participants assessed themselves as having Fitzpatrick skin types II (35.2%) or III (56.7%), while only approximately 3.6% and 4.5% assessed themselves as having skin types I and IV, respectively. The results of the Fitzpatrick skin type assessments made by dermatologists were similar: 96.9% of participants were assessed as having Fitzpatrick skin types II (43.0%) and III (53.8%); approximately 1.9% and 1.3% were assessed as having Fitzpatrick skin types I and IV, respectively. Results showed that 80.2% of all participants assessed their skin type in the same way as the dermatologist; 13.5% assessed their skin type as darker and 6.3% (49/783) assessed it as lighter. A quantitative analysis of Fitzpatrick skin type and sex showed that significantly more male participants than female participants assessed their Fitzpatrick skin type darker than their actual skin type (P<.01).

Overall, 47.6% of participants reported having had sunburn rarely in the past, while 36.9% and 14.0% had experienced sunburn once per year and several times per year, respectively. Approximately 1.4% of participants reported never having a sunburn. More of the male participants made use of comprehensive sun protection using all methods listed (34.5%; P<.05) or a combination of sunscreen and sun-protective clothing (14.9%; P<.01) than the female participants who relied more frequently on sunscreen alone (29.5%; P<.01) or a combination of sunscreen and staying in the shade (29.5%; P<.01)

In general it was clear that sunscreen, either alone or in combination with other sun-protection methods, was used most frequently (88.0%); 58.0% protected themselves by staying in the shade, while 48.0% used suitable sun-protective clothing. Only 3.6% of participants did not protect themselves using any of the suggested methods.

A total of 661 categorized skin lesions were found in 377 participants. Of these lesions, 491 were Nc and 121 were Ne. Twenty-four of the skin lesions were suspected precancerous lesions, 13 were suspected BCC, 2 were suspected MM, and 10 were suspected other skin tumor (Table 2). Overall, male participants who were diagnosed with at least 1 skin lesion (average age, 44.0 years) were significantly older than the women (average age, 39.3 years)(P<.01). Similar findings were observed in participants with at least 1 Nc (men, 43.3 years; women, 38.7 years; P<.01) and at least 1 Ne (men, 44.2 years; women, 38.0 years; P<.05). With regard to the individual risk for developing skin cancer, 32.6% of participants were considered to be at low risk, 64.9% were at moderate risk, and 2.6% were at high risk.

Approximately 61.5% of 377 participants who were diagnosed with at least 1 categorized skin lesion were advised to have a specific skin lesion checked by a dermatologist or to have a full examination for skin cancer once every 12 months. Furthermore, 22.5% were advised to follow-up biannually and 11.7% were advised to follow-up once every 2 years. Of the remaining participants who were advised to have follow-ups, 0.3% were advised to have a skin examination once every 3 months after having had MM, and 4.0% were advised to have follow-up once every 18 months. Overall, follow-up was recommended within 1 year in 84.4% of cases and within 1 to 2 years in 15.6% (Table 3).

Subsequent histological analysis of the excised tissue resulted in a diagnosis of only 21 clinically significant skin conditions. One case of Bowen disease and 1 case of BCC was confirmed. Histological analysis identified the remaining 19 excised skin lesions, which included the 2 suspected MMs, as dysplastic nevi.

Comment

The aim of this cross-sectional study was to examine the importance and effectiveness of employee skin cancer screening programs. In comparison with the total workforce, significantly more women took part than men. Female participants were significantly younger than male participants, which mirrors the findings of prior studies showing that screening programs reach women more frequently than men and that women who participate in screenings are also younger on average in comparison to men.^7-13 Men and older individuals usually are underrepresented.^7,13 The average age of participants in our study was 42.3 years, which is lower than in the SCREEN (Skin Cancer Research to Provide Evidence for Effectiveness of Screening in Northern Germany) study (average age, 49.7 years).¹³ The average age in our study also is likely to be lower than patients who undergo skin cancer screenings offered by statutory health insurance providers in Germany, which has a minimum age restriction of 35 years; however, it is comparable to the average age of participants in other employee screening programs and therefore represents the average age of individuals employed in Germany.^15,16

The employee skin cancer screening program in this study generated a high level of interest, indicated by the fact that all available appointments had been booked just 36 hours after the screening was announced. Furthermore, there was a waiting list of approximately 300 employees who were not able to undergo a skin examination. For logistical reasons, the number of participants was limited to 10% of the workforce. The high level of interest is an indication of increased awareness of the importance of recognizing skin tumors early and the associated need for information as well as the need to undergo screening for skin cancer as a precaution. This observation also can be made with regard to the skin cancer screening introduced by statutory health insurance providers in Germany. Studies published by Augustin et al²⁰ and Kornek et al^21,22 confirm that skin cancer screenings have gained wide acceptance in Germany because they were introduced by statutory health insurance providers in 2008. The number of skin cancer screenings carried out by dermatologists in Germany also is increasing.^20-22 Although approximately 19% of those eligible to participate took part in the SCREEN pilot project,¹³ approximately 31% of individuals who were eligible to participate took part in skin cancer screenings offered by statutory health insurance providers in Germany in 2012, and the percentage is rising.²³ Two important factors affecting the high level of interest in the employee screening program used in our study were undoubtedly the advantages of the examination taking place during working hours and being held on the occupational health services’ premises in the workplace, which helped participants avoid the cost of travel and wait times associated with visiting a medical practice.

Of 783 participants included in this study, 377 displayed at least 1 categorized skin lesion; the majority were suspicious melanocytic nevi. This high incidence rate suggested that regular skin cancer screenings are useful, as it has been shown that there is a correlation between higher numbers of melanocytic nevi and increased risk for developing melanoma.²⁴

In a study by Winkler et al,²⁵ a skin cancer screening of 1658 bank and insurance employees found that 33.8% of those examined displayed at least 1 atypical melanocytic nevus and 27.2% displayed more than 50 melanocytic nevi (compared to 12.8% with ≥50 melanocytic nevi in the current study). The risk for developing skin cancer was classified as intermediate or high in 54.5% (compared to 67.5% at moderate or high risk in the current study).²⁵ Therefore, the rate of suspicious skin lesions was lower in the population of the study by Winkler et al²⁵ in comparison to the population of the current study. As the overall number of melanocytic nevi and the individual risk for skin cancer, however, was underestimated by the majority of the bank and insurance employees,²⁵ employee skin cancer screening programs can be used as a potentially effective tool to make employees aware of the issue and sensitizing them to it. Employee screening in addition to a final diagnosis can contribute to ensuring suitable treatment is started. For example, in the large-scale employee screening published by Schaefer et al¹⁵ and Augustin et al,¹⁶ 48,665 and 90,880 employees, respectively, were screened for inflammatory and noninflammatory skin diseases, and 19% and 27% of participants, respectively, were diagnosed with skin lesions that required treatment.

Participants in the current study were given no further treatment or advice. Recommendations were made that participants monitor suspicious skin lesions or have them removed. With regard to future screening, 84.4% of participants with at least 1 categorized skin lesion were advised to have a regular follow-up within 1 year, while 15.6% were advised to follow-up within 1 to 2 years. Therefore, a period of 2 years before the next checkup, the period between screenings offered by statutory health insurance providers in Germany,¹² was considered too long for the majority of participants, according to the dermatologists involved with our study.

It should be noted that the study group examined in the current study was a homogeneous group of employees of a technical company only and is therefore relatively selective. Nevertheless, despite the comparatively selective and young participant group, these examinations provide evidence of the importance of skin cancer screening programs for a wider population.

Conclusion

The high rate of suspicious skin lesions diagnosed demonstrated the effectiveness of skin cancer screenings organized in the workplace, which should be recommended for all employees, not only those who are at high risk for developing skin cancer due to the nature of their work, such as those who work outdoors. It should be noted that the study group examined in the current study was a homogeneous group of employees of a technical company only and is therefore relatively selective. Nevertheless, despite the comparatively selective and young participant group, these examinations provide evidence of the importance of skin cancer screening programs for a wider population.

Case Report

A 23-year-old woman presented with a horizontal split along the midline of the right great toenail associated with some tenderness of 2 to 3 months’ duration. Approximately 5 years prior, she noticed a bluish-colored area under the nail that had been steadily increasing in size. She denied a history of trauma, drainage, or bleeding. There was no history of other nail abnormalities. Her medications and personal, family, and social history were noncontributory.

Physical examination of the right great toenail revealed a horizontal split of the nail plate with a bluish hue visible under the nail plate (Figure 1A). The remaining toenails and fingernails were normal. A punch biopsy of the nail bed was performed with a presumptive clinical diagnosis of subungual melanoma versus melanocytic nevus versus cyst (Figure 1B). Nail plate avulsion revealed a blackened nail bed dotted with areas of bluish color and a red friable nodule present focally. Upon further inspection, extension was apparent into the distal matrix.

Histopathologic examination revealed a cystic structure with an epithelial lining mostly reminiscent of an isthmus catagen cyst admixed with the presence of both an intermittent focal granular layer and an eosinophilic cuticle surrounding pink laminated keratin, most consistent with a diagnosis of subungual onycholemmal cyst (SOC)(Figure 2). A reexcision was performed with removal of half of the nail bed, including a portion of the distal matrix extending inferiorly to the bone. Variably sized, epithelium-lined, keratin-filled cystic structures emanated from the nail bed epithelium. There were foci of hemorrhage and granulation tissue secondary to cyst rupture (Figure 3). The defect healed by secondary intention. No clinical evidence of recurrence was seen at 6-month follow-up.

Subungual onycholemmal cysts, also known as subungual epidermoid cysts or subungual epidermoid inclusions, are rare and distinctive nail abnormalities occurring in the dermis of the nail bed. We present a case of an SOC in a toenail mimicking subungual malignant melanoma.

Originally described by Samman¹ in 1959, SOCs were attributed to trauma to the nail with resultant implantation of the epidermis into the deeper tissue. Lewin^2,3 examined 90 postmortem fingernail and nail bed samples and found 8 subungual epidermoid cysts associated with clubbing of the fingernails. He postulated that the early pathogenesis of clubbing involved dermal fibroblast proliferation in the nail bed, leading to sequestration of nail bed epithelium into the dermis with resultant cyst formation. Microscopic subungual cysts also were identified in normal-appearing nails without evidence of trauma, thought to have arisen from the tips of the nail bed rete ridges by a process of bulbous proliferation rather than sequestration. These findings in normal nails suggest that SOCs may represent a more common entity than previously recognized.

It is imperative to recognize the presence of nail unit tumors early because of the risk for permanent nail plate dystrophy and the possibility of a malignant tumor.^4,5 Subungual onycholemmal cysts may present with a wide spectrum of clinical findings including marked subungual hyperkeratosis, onychodystrophy, ridging, nail bed pigmentation, clubbing, thickening, or less often a normal-appearing nail. Based on reported cases, several trends are evident. Although nail dystrophy is most often asymptomatic, pain is not uncommon.^5,6 It most commonly involves single digits, predominantly thumbs and great toenails.^7,8 This predilection suggests that trauma or other local factors may be involved in its pathogenesis. Of note, trauma to the nail may occur years before the development of the lesions or it may not be recalled at all.

Diagnosis requires a degree of clinical suspicion and a nail bed biopsy with partial or total nail plate avulsion to visualize the pathologic portion of the nail bed. Because surgical intervention may lead to the implantation of epithelium, recurrences after nail biopsy or excision may occur.

In contrast to epidermal inclusion cysts arising in the skin, most SOCs do not have a granular layer.⁹ Hair and nails represent analogous differentiation products of the ectoderm. The nail matrix is homologous to portions of the hair matrix, while the nail bed epithelium is comparable to the outer root sheath of the hair follicle.⁷ Subungual onycholemmal cysts originate from the nail bed epithelium, which keratinizes in the absence of a granular layer, similar to the follicular isthmus outer root sheath. Thus, SOCs are comparable to the outer root sheath–derived isthmus-catagen cysts because of their abrupt central keratinization.⁸

Subungual onycholemmal cysts also must be distinguished from slowly growing malignant tumors of the nail bed epithelium, referred to as onycholemmal carcinomas by Alessi et al.¹⁰ This entity characteristically presents in elderly patients as a slowly growing, circumscribed, subungual discoloration that may ulcerate, destroying the nail apparatus and penetrating the phalangeal bone. On histopathology, it is characterized by small cysts filled with eosinophilic keratin devoid of a granular layer and lined by atypical squamous epithelium accompanied by solid nests and strands of atypical keratinocytes within the dermis.¹¹ When a cystic component and clear cells predominate, the designation of malignant proliferating onycholemmal cyst has been applied. Its infiltrative growth pattern with destruction of the underlying bone makes it an important entity to exclude when considering the differential diagnosis of tumors of the nail bed.

Subungual melanomas comprise only 1% to 3% of malignant melanomas and 85% are initially misdiagnosed due to their rarity and nonspecific variable presentation. Aside from clinical evidence of Hutchinson sign in the early stages in almost all cases, accurate diagnosis of subungual melanoma and differentiation from SOCs relies on histopathology. A biopsy is necessary to make the diagnosis, but even microscopic findings may be nonspecific during the early stages.

Conclusion

We report a case of a 23-year-old woman with horizontal ridging and tenderness of the right great toenail associated with pigmentation of 5 years’ duration due to an SOC. The etiology of these subungual cysts, with or without nail abnormalities, still remains unclear. Its predilection for the thumbs and great toenails suggests that trauma or other local factors may be involved in its pathogenesis. Because of the rarity of this entity, there are no guidelines for surgical treatment. Subungual onycholemmal cysts may be an underrecognized and more common entity that must be considered when discussing tumors of the nail unit.

A great volume of HIV and AIDS research enters the medical literature every month. It’s difficult to monitor everything, so here’s a quick look at some notable news items and journal articles published over the past few weeks.

Text message reminders are a promising intervention that can be used to increase HIV care compliance when logistically feasible, according to a meta-analysis published in AIDS Care.

A study published in AIDS found that people living with HIV who are older than age 65years are at higher risk of comorbidities than are other fee-for-service Medicare beneficiaries.

A study in Thailand found a marked divergence of HIV DNA values between untreated and treated groups that occurred within the first 2 weeks of antiretroviral therapy (ART) and increased with time. The authors conclude that very-early ART offers the opportunity to significantly reduce the frequency of cells harboring HIV DNA.

An independent source of HIV RNA contributes to viral rebound within the cerebrospinal fluid after treatment interruption, according to a study in Virus Evolution. The most likely source of compartmentalized HIV RNA is a CNS reservoir that would need to be targeted to achieve complete HIV eradication, investigators said.

A recent six-site U.S. study discovered that 36% of nondrinking persons living with HIV in routine clinical care had a prior alcohol use disorder.

A study in HIV Medicine found that treatment of patients infected with hepatitis C virus and coinfected with HCV/HIV with all-oral direct-acting antiviral combinations, under real-life conditions, led to high and similar rates of sustained virologic response 12 weeks after the end of therapy.

A first-of-its-kind study in Tanzania demonstrated a significantly increased risk of acquiring HIV for lymphatic filariasis-infected individuals.

A clinical trial of HIV-infected adults treated with efavirenz-based antiretroviral therapy found that the late virologic failure rate was very low after successful suppression. The authors said virologic monitoring, if achievable in routine clinical practice, involving infrequent measurements might be considered.

The introduction of a low viral load threshold provides crucial improvements in recent infection testing algorithms, according to a study in AIDS. However, the authors said it does not eliminate non-zero “false-recent” rates, and mean durations of “recent” infection must be consistently estimated.

The risk of virologic failure in a population of HIV-infected patients on antiretroviral therapy, who achieved viral suppression at less than 20 copies/mL, was no different for patients who remained fully suppressed, compared with those who experienced subsequent episodes of very low level viremia.

A British study found that HIV self-testing among men who have sex with men represents an opportunity to reduce barriers to HIV testing and enhance prevention and access to care.

Hepatitis B virus coinfection was the most important risk factor for liver fibrosis and cirrhosis in HIV patients, and should be diagnosed early in HIV care to optimize treatment outcomes, according to a report in Tropical Medicine & International Health.

A recent study found that higher HIV RNA and wasting before antiretroviral therapy were independent risk factors for pneumonia in early ART-treated HIV-infected infants.

New information increases concerns about the association between the hormonal contraceptive depot medroxyprogesterone acetate and HIV acquisition risk in women, researchers said in a recent study. If the association is causal, the magnitude of effect is likely a hazard ratio of 1.5, although investigators said data for other hormonal contraceptive methods are largely reassuring.

A study of virally suppressed HIV-infected men with extensive antiretroviral exposure found no consistent associations between use of specific ART drugs and both subclinical coronary plaque presence and extent. Investigators said the findings support the hypothesis that, among virally suppressed persons, type of ART used is not in general a major determinant of subclinical coronary plaque risk.

More cost-effective and impactful HIV-prevention investments could be achieved across sub-Saharan Africa if domestic and international funders were to align strategically to build an aggregate funding pattern guided by the emerging understanding of local dynamics and epidemic drivers, a Lancet HIV study found.

A cross-sectional cohort study found evidence of endothelial dysfunction in HIV infection and in untreated compared to treated HIV infection, although asymmetric dimethylarginine (a marker of endothelial dysfunction) was not associated with subclinical atherosclerosis.

A modeling study in the journal AIDS concluded that, in mature HIV epidemics, between 3%-6% of transmission events are attributable to acute HIV infection among people who inject drugs.

The HIV epidemic serves as an amplifier of TB outbreaks by providing a reservoir of susceptible hosts, a study in eLife found, but HIV coinfection is not a direct driver for the emergence and transmission of drug-resistant strains.

A recent study of HIV-infected patients coinfected with hepatitis B and C viruses found that, despite increasing use of antiretrovirals, no clear reduction in end-stage liver disease risk was observed. The authors said treatment with direct acting antivirals for HCV and wider use of tenofovir-based regimens for HBV should be prioritized for coinfected patients.

HIV incidence, prevalence, and undiagnosed infections can be estimated using HIV case surveillance data and information on first CD4 test result after diagnosis, according to analysis published in JAIDS.

Micrograph showing BCP-ALL

Screening for genetic abnormalities can provide a more accurate prediction of outcomes in children with relapsed B-cell precursor acute lymphoblastic leukemia (BCP-ALL), according to a study published in Blood.

Researchers found that mutations or deletions in TP53, NR3C1, BTG1, and NRAS were associated with inferior outcomes in relapsed BCP-ALL.

And screening for these abnormalities could improve upon the predictive accuracy of clinical risk factors.

“Current methods used to guide treatment for relapsed leukemia are not accurate enough, with some children believed to have a good chance of survival actually responding very poorly to chemotherapy,” said study author Anthony Moorman, PhD, of Newcastle University in Newcastle upon Tyne, UK.

“Screening patients at relapse for key genetic abnormalities that influence outcome will ensure that treatment can be personalized, thereby improving their chances of survival.”

For this study, Dr Moorman and his colleagues analyzed cytogenetic data from 427 children with relapsed BCP-ALL and screened 238 patients with a marrow relapse for certain copy number alterations and mutations.

According to univariate analysis, alterations in TP53, NR3C1 deletions, and BTG1 deletions were significantly associated with patient outcomes.

Patients with TP53 alterations had a higher risk of progression (hazard ratio [HR]=2.36, P<0.001) and death (HR=2.56, P<0.001), as did patients with deletions in NR3C1 and BTG1.

Because both NR3C1 and BTG1 are implicated in resistance to glucocorticoids and the deletions are mutually exclusive, the researchers considered the effect of the deletions together. So for patients with NR3C1 and BTG1 deletions, the HR for progression was 2.15 (P=0.002), and the HR for death was 1.91 (P=0.015).

Patients with NRAS mutations had an increased risk of progression and death as well, but this did not reach statistical significance.

The researchers also found that patients who were standard risk according to clinical characteristics but, at the time of relapse, had one or more high-risk genetic abnormalities had poorer outcomes.

Standard-risk patients with a TP53 alteration had an increased risk of death (HR=2.56, P<0.001), as did standard-risk patients with NR3C1 and BTG1 deletions (HR=1.91, P=0.015).

Standard-risk patients with NRAS mutations and high hyperdiploidy had an increased risk of progression (HR=3.17, P=0.026) and death (HR=3.41, P=0.032).

The researchers concluded that the outcomes of clinical standard-risk patients with high-risk cytogenetics were equivalent to outcomes of clinical high-risk patients.

The team therefore believes that screening BCP-ALL patients for the aforementioned genetic abnormalities at relapse will improve patient stratification and outcomes.

Screening for genetic abnormalities can provide a more accurate prediction of outcomes in children with relapsed B-cell precursor acute lymphoblastic leukemia (BCP-ALL), according to a study published in Blood.

Researchers found that mutations or deletions in TP53, NR3C1, BTG1, and NRAS were associated with inferior outcomes in relapsed BCP-ALL.

And screening for these abnormalities could improve upon the predictive accuracy of clinical risk factors.

“Current methods used to guide treatment for relapsed leukemia are not accurate enough, with some children believed to have a good chance of survival actually responding very poorly to chemotherapy,” said study author Anthony Moorman, PhD, of Newcastle University in Newcastle upon Tyne, UK.

“Screening patients at relapse for key genetic abnormalities that influence outcome will ensure that treatment can be personalized, thereby improving their chances of survival.”

For this study, Dr Moorman and his colleagues analyzed cytogenetic data from 427 children with relapsed BCP-ALL and screened 238 patients with a marrow relapse for certain copy number alterations and mutations.

According to univariate analysis, alterations in TP53, NR3C1 deletions, and BTG1 deletions were significantly associated with patient outcomes.

Patients with TP53 alterations had a higher risk of progression (hazard ratio [HR]=2.36, P<0.001) and death (HR=2.56, P<0.001), as did patients with deletions in NR3C1 and BTG1.
