ROME – Treating patients with heterozygous familial hypercholesterolemia (HeFH) with PCSK9 inhibitors can reduce their need for lipoprotein apheresis and its associated costs, Patrick M. Moriarty, MD, said in a video interview at the annual congress of the European Society of Cardiology.

In the randomized, phase III ODYSSEY ESCAPE trial, HeFH patients who underwent weekly apheresis were treated with either alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, or placebo. At the end of the study, the alirocumab-treated patients had a 75% greater reduction in need for apheresis, compared with those on placebo – a statistically significant difference.

With a price tag of $50,000-$75,000 a year for lipoprotein apheresis, compared with the roughly $12,000 cost for a PCSK9 inhibitor, this represents a significant savings for patients with HeFH, which occurs in roughly 1 in 200 people worldwide, Dr. Moriarty of the University of Kansas, Kansas City, told reporter Bruce Jancin.

Increased incidence of Guillain-Barré syndrome corresponded closely with patterns of Zika virus disease incidence in Central and South America from April 2015 through March 2016, according to results from a new temporal and graphic analysis.

The findings show Guillain-Barré syndrome (GBS) cases increasing from 100% to nearly 900% above previously recorded baseline rates during periods of Zika virus transmission in El Salvador, the Dominican Republic, Colombia, Honduras, Suriname, Venezuela, and the Brazilian state of Bahia (N Engl J Med. 2016 Aug 31. doi: 10.1056/NEJMc1609015).

The analysis of the yearlong period also revealed that declines in GBS incidence accompanied declines in Zika virus disease when and where transmission began to wane. The researchers, led by Marcos A. Espinal, MD, DrPH, of the Pan American Health Organization in Washington, did not find significant associations between co-circulation of dengue virus and GBS incidence. The study, which looked at 164,237 confirmed and suspected cases of Zika virus disease and 1,474 cases of GBS, found a 75% higher Zika virus disease incidence rate in women, which Dr. Espinal and colleagues said might be attributable to differences in health care–seeking behavior. GBS incidence, meanwhile, was 28% higher among males. The higher rate of GBS in men, the authors said, was consistent with findings from previous epidemiological studies of GBS.

While the new results did not show that Zika virus causes GBS, Dr. Espinal and colleagues wrote, they argued that they were indicative of a strong association, adding that GBS “could serve as a sentinel for Zika virus disease and other neurological disorders linked to Zika virus,” including microcephaly.

Most of the study authors worked for the Pan American Health Organization or for national health agencies in the data-contributing countries. None declared conflicts of interest.

The summer is over, football season has begun, and team physicians are busy trying to manage and treat the plethora of injuries that come with the game. Football is one of the most popular sports played by young athletes. Youth participation (ages 6-14 years) in tackle football was 2.169 million in 2015, according to a study conducted by the Physical Activity Council and presented by USA Football. There were 1.084 million boys (and 1500 girls) playing high school football in the 2014-2015 season, nearly twice the number of the next most popular sport, track and field, according to the National Federation of State High School Associations.Due to the sheer volume of athletes and high-impact nature of the game, football leads all other sports in the number of sustained injuries.

Team physicians have the leadership role in the organization, management, and provision of care of the athletes on the team. The roles and responsibilities of the team physician are ever-evolving. The team physician has to meet certain medical qualifications and education requirements, and understand the ethical and medicolegal issues.

The American Academy of Orthopaedic Surgeons and several other medical associations have put together a Team Physician Consensus Statement (available at http://bit.ly/2b8rOzS). All team physicians, coaches, and athletic trainers should read and understand this statement, as it delineates the qualifications, duties, and responsibilities of the team physician.

Our Football Issue focuses on the most common injuries that the team physician will encounter during the season. Our goal is to create a comprehensive guide for the team physician on the acute management of these injuries. As team physicians, we have to make quick return-to-play decisions that are often difficult, as we are dealing with extremely competitive athletes and coaches in the heat of the moment. Since we can’t control the high levels of adrenalin, loud stadium, or rapid speed of the game, we need to be prepared to perform a comprehensive evaluation and diagnosis under these circumstances. This return-to-play decision should be based solely on the severity of the injury and safety of the player. As a team physician, you are responsible for making the “final call” on when the player is safe to return to the game.

This issue includes a section on the most common medical issues (ophthalmology, dental, and dermatology), concussion, exertional heat stroke, knee injuries, and foot and ankle injuries. We also have a special list of the most common items to include in the athletic trainer’s medical bag when covering a high school or collegiate football game (see page 376). Our prominent contributing authors all have extensive experience covering high school, collegiate, and professional teams.

I hope that our Football Issue helps you to keep your athletes safe and injury-free, which is necessary to have a successful season. Remember, as the team physician, your primary focus is the well being of the players. The success of the team only comes when the players are healthy. A cohesive, well-organized medical team, led by the head athletic trainer and team physician, is a key component to the care of the athletes. It truly takes a village to provide top-notch medical care to a football team.

Illustrative Case

A 25-year-old woman who is 16 weeks pregnant with her first child is experiencing increased vaginal discharge associated with vaginal itching. A microscopic examination of the discharge confirms your suspicions of vaginal candidiasis. Is oral fluconazole or a topical azole your treatment of choice?

Because of the increased production of sex hormones, vaginal candidiasis is common during pregnancy, affecting up to 10% of pregnant women in the United States.^1,2 Treatment options include oral fluconazole and a variety of topical azoles. Although topical azoles are recommended as first-line therapy,³ the ease of oral therapy makes it an attractive treatment option.⁴ The safety of oral fluconazole during pregnancy, however, has recently come under scrutiny.

Case reports have linked high-dose fluconazole use during pregnancy with congenital malformations.^5,6 These case reports led to epidemiological studies evaluating fluconazole’s safety, but, in these studies, no association with congenital malformations was found.^7,8

A large cohort study involving 1079 fluconazole-exposed pregnancies and 170,453 unexposed pregnancies found no increased risk of congenital malformations or stillbirth; rates of spontaneous abortion and miscarriage were not evaluated.⁹ A prospective cohort study of 226 pregnant women found no association between fluconazole use during the first trimester and miscarriages.¹⁰ However, the validity of both studies’ findings was limited by small numbers of participants. The current study is the largest to date to evaluate whether use of fluconazole compared to that of topical azoles in early pregnancy is associated with increased rates of spontaneous abortion and stillbirth.

Study Summary

Fluconazole significantly increases risk of miscarriage, but not stillbirth

This nationwide cohort study, conducted using the Medical Birth Register in Denmark, evaluated more than 1.4 million pregnancies occurring from 1997 to 2013 for exposure to oral fluconazole between 7 and 22 weeks’ gestation. Each oral fluconazole-exposed pregnancy was matched with up to 4 unexposed pregnancies (based on propensity score, maternal age, calendar year, and gestational age) and to pregnancies exposed to intravaginal formulations of topical azoles. Exposure to fluconazole was documented based on filled prescriptions from the National Prescription Register. Primary outcomes were rates of spontaneous abortion (loss before 22 weeks) and stillbirth (loss after 23 weeks).

Rates of spontaneous abortion. From the total cohort of more than 1.4 million pregnancies, 3315 were exposed to oral fluconazole between 7 and 22 weeks’ gestation. Spontaneous abortions occurred in 147 of the 3315 fluconazole-exposed pregnancies and in 563 of 13,246 unexposed, matched pregnancies (hazard ratio [HR]=1.48; 95% confidence interval [CI], 1.23-1.77).

Rates of stillbirth. Of 5382 pregnancies exposed to fluconazole from week 7 to birth, 21 resulted in stillbirth; 77 stillbirths occurred in the 21,506 unexposed matched pregnancies (HR=1.32; 95% CI, 0.82-2.14). In a sensitivity analysis, however, higher doses of fluconazole (350 mg) were 4 times more likely to be associated with stillbirth (HR=4.10; 95% CI, 1.89-8.90) than lower doses (150 mg) (HR= 0.99; 95% CI, 0.56-1.74).

Oral fluconazole vs topical azole. Use of oral fluconazole in pregnancy was associated with an increased risk of spontaneous abortion when compared to topical azole use: 130 of 2823 pregnancies vs 118 of 2823 pregnancies, respectively (HR=1.62; 95% CI, 1.26-2.07), but not an increased risk of stillbirths: 20 of 4301 pregnancies vs 22 of 4301 pregnancies, respectively (HR=1.18; 95% CI, 0.64-2.16).

What’s New

A sizeable study with a treatment comparison

The authors found that exposure in early pregnancy to oral fluconazole, as compared to topical azoles, increases the risk of spontaneous abortion. By comparing treatments in a sensitivity analysis, the confounder of Candida infections causing spontaneous abortion was removed. In addition, when considering the ease of dosing of fluconazole as compared with topical imidazoles, this study challenges the balance of ease of use with safety.

Caveats

A skewed population and limited generalizability?

Given the ease of using oral fluconazole vs daily topical azole therapy, many physicians and patients may still opt for oral treatment.

This large cohort study using the National Patient Register in Denmark may not be generalizable to a larger, non-Scandinavian population. Since a hospital registry was used, those not seeking care through the hospital were likely missed. If patients seeking care through the hospital had a higher risk of abortion, this may have biased the results. However, this would not have affected the results for the comparison between the 2 active treatments.

In addition, the study focused on women exposed from 7 to 22 weeks’ gestation; the findings may not be generalizable to fluconazole exposure prior to 7 weeks. Likewise, the registry is unlikely to capture very early spontaneous abortions that are not recognized clinically. In all, given the large sample size and the care taken to match each exposed pregnancy with up to 4 unexposed pregnancies, these limitations are likely to have had little influence on the overall findings of the study.

Challenges to Implementation

Balancing ease of use with safety

Given the ease of using oral fluconazole vs daily topical azole therapy, many physicians and patients may still opt for oral treatment.

In a sensitivity analysis, however, higher doses of fluconazole (350 mg) were 4 times more likely to be associated with stillbirth (HR=4.10; 95% CI, 1.89-8.90) than lower doses (150 mg) (HR= 0.99; 95% CI, 0.56-1.74).

Oral fluconazole vs topical azole. Use of oral fluconazole in pregnancy was associated with an increased risk of spontaneous abortion when compared to topical azole use: 130 of 2823 pregnancies vs 118 of 2823 pregnancies, respectively (HR=1.62; 95% CI, 1.26-2.07), but not an increased risk of stillbirths: 20 of 4301 pregnancies vs 22 of 4301 pregnancies, respectively (HR=1.18; 95% CI, 0.64-2.16).

What’s New

A sizeable study with a treatment comparison

The authors found that exposure in early pregnancy to oral fluconazole, as compared to topical azoles, increases the risk of spontaneous abortion. By comparing treatments in a sensitivity analysis, the confounder of Candida infections causing spontaneous abortion was removed. In addition, when considering the ease of dosing of fluconazole as compared with topical imidazoles, this study challenges the balance of ease of use with safety.

Caveats

A skewed population and limited generalizability?

Given the ease of using oral fluconazole vs daily topical azole therapy, many physicians and patients may still opt for oral treatment.

This large cohort study using the National Patient Register in Denmark may not be generalizable to a larger, non-Scandinavian population. Since a hospital registry was used, those not seeking care through the hospital were likely missed. If patients seeking care through the hospital had a higher risk of abortion, this may have biased the results. However, this would not have affected the results for the comparison between the 2 active treatments.

In addition, the study focused on women exposed from 7 to 22 weeks’ gestation; the findings may not be generalizable to fluconazole exposure prior to 7 weeks. Likewise, the registry is unlikely to capture very early spontaneous abortions that are not recognized clinically. In all, given the large sample size and the care taken to match each exposed pregnancy with up to 4 unexposed pregnancies, these limitations are likely to have had little influence on the overall findings of the study.

Challenges to Implementation

Balancing ease of use with safety

Given the ease of using oral fluconazole vs daily topical azole therapy, many physicians and patients may still opt for oral treatment.

Along with global endometrial ablation, diagnostic and minor operative hysteroscopy are excellent procedures to bring into your office environment. These operations are generally of short duration and provide little risk to the patient. Moreover, reimbursement exceeds that for the hospital setting. A constant revenue stream can be created after an initial moderate expenditure.

The key to a successful office procedure is patient comfort; this begins with minimizing pain and trauma. In our practice, we note decreased pain when performing vaginoscopy and hysteroscopy without the use of a speculum or tenaculum.

The benefits of integrating hysteroscopy into office practice are compelling. Most importantly, patients appreciate the comfort and convenience of having hysteroscopic procedures done in a familiar setting. Patients can generally be in and out of the office in less than 30 minutes for a diagnostic procedure, and in less than 1-2 hours for an operative procedure.

Not only is an in-office approach patient centered and clinically valuable, but it is more efficient and economically favorable for the gynecologic surgeon. Physicians earn higher reimbursement for diagnostic hysteroscopies, as well as many therapeutic and operative hysteroscopies, when these procedures are done in the office rather than when they’re performed in a hospital or an outpatient center.

Transitioning to in-office hysteroscopy need not be daunting: The setup is relatively simple and does not require an operating suite, just a dedicated exam room. And the need for premedication and local anesthesia can be low, particularly when a vaginoscopic approach to hysteroscopy is employed. For most gynecologic surgeons, the necessary skills and comfort levels fall into place after only a few vaginoscopic procedures.

A vaginoscopic approach avoids the use of a vaginal speculum or cervical tenaculum, significantly decreasing discomfort or pain. Not using these instruments is the only difference between this and traditional hysteroscopy. It is a less invasive approach that is much more tolerable for patients. And for the surgeon, it can be easier and quicker and provides equally good visualization without any impairment in cervical passage.

Described in the literature as far back as the 1950s, vaginoscopy has its roots in the pediatric/adolescent population, where it was used for the removal of foreign bodies and evaluation of the vagina and external cervical os.

More recently, Stefano Bettocchi, MD, and Luigi Selvaggi, MD, in Italy were the first to describe a vaginoscopic approach to hysteroscopy for evaluating the endocervical canal and uterine cavity.

In a series of papers from 1997 to 2004, Dr. Bettocchi and Dr. Selvaggi documented their efforts to improve patient tolerance during diagnostic hysteroscopies. When they used both the speculum and tenaculum in 163 patients, with local anesthesia, 8% reported severe pain, 11% reported moderate pain, and 69% reported mild pain. Only 12% reported no discomfort. With speculum use only, and no anesthesia, in 308 patients, none reported severe pain, 2% reported moderate pain, 32% reported mild pain, and 66% reported no discomfort. When neither instrument was used (again, no anesthesia), patient discomfort was nearly eliminated: In 680 procedures, patients had a 96% no-discomfort rate (J Am Assoc Gynecol Laparosc. 1997 Feb;4[2]:255-8; Curr Opin Obstet Gynecol. 2003 Aug;15[4]:303-8; Obstet Gynecol Clin North Am. 2004 Sep;31[3]:641-54, xi).

Since then, research has affirmed the differences in patient tolerance and has shown that there is no significant difference between traditional and vaginoscopic hysteroscopy in the rate of procedure failure (0%-10%).

In my practice, in addition to vaginal or cervical examination and evaluation of the uterine cavity, I utilize a vaginoscopic approach to perform minor therapeutic and operative procedures such as biopsies, polypectomies, tubal occlusion using the Essure system, and removal of lost intrauterine devices. I can assess infertility, trauma, abnormal uterine bleeding, and mesh erosion, and provide pre- and postsurgical evaluations. In all of these cases, I use minimal premedication and only rarely need any local anesthetic and/or sedation.

Instrumentation and technique

There are a variety of hysteroscopes available on the market, from single-channel flexible diagnostic hysteroscopes that are 3 mm to 4 mm in diameter, to “see-and-treat” operative hysteroscopes that are rigid and have various diameters and camera lens angles.

A hysteroscope with a 5.5-mm outer diameter works well for a vaginoscopic approach that avoids cervical dilation. Accessory instrumentation includes semirigid 5 Fr 35-cm–long biopsy forceps, scissors, and alligator forceps.

In timing the procedure, our main goal is a thin uterine lining. This can be achieved by scheduling the procedure during the early proliferative phase of the menstrual cycle or by using a gonadotropin-releasing hormone agonist or a transdermal or transvaginal contraceptive medication.

By far the most important element of pain control and analgesia is the time spent with each patient to thoroughly discuss the experience of hysteroscopy and to set expectations about what she will hear, see, and feel. An unexpected experience can worsen anxiety, which in turn can worsen pain. If everything is as familiar and relaxed as possible, there will be little need for analgesia.

I tell patients in preprocedure counseling that the distention of the uterine walls usually causes some cramping, and that NSAIDs can minimize this cramping. In rare cases, when a patient is very worried about her pain tolerance, I will prescribe diazepam. However, many of my patients opt to do nothing other than take ibuprofen. On a case-by-case basis, you can determine with your patient what type and level of analgesia and preprocedure medication will be best.

Paracervical blocks are an option for some surgical patients, but I advise my patients to move forward without the block and assure them that it can be administered later if needed. Thus far, I’ve never proceeded with a paracervical block. There are other methods and sites for introducing local anesthesia, including intracervical, by injection or topical, or topical intracavitary techniques. Nevertheless, it is unclear from randomized controlled trials whether local anesthesia is effective. Trials of paracervical blocks similarly have had inconsistent outcomes.

I do commonly premedicate patients – mainly nulliparous patients and postmenopausal patients – with misoprostol, which softens the cervix and facilitates an easier entry of the hysteroscope into the cervix.

Published studies on misoprostol administration before hysteroscopy have had mixed results. A Cochrane review from 2015 concluded there is moderate-quality evidence in support of preoperative ripening with the agent, while another meta-analysis also published in 2015 concluded that data are poor and do not support its use. Recently, however, there appear to be more supportive studies demonstrating or suggesting that misoprostol is effective in reducing discomfort.

Patient discomfort is also minimized when there is little manipulation of the hysteroscope. Scopes that are angled (12, 25, or 30 degrees) allow optimal visualization with minimal movement; the scope can be brought to the midline of the uterine cavity and the light cord rotated to the 3:00 and 9:00 o’clock positions to enable visualization of the cornu. A 0-degree scope, on the other hand, must be manipulated quite a bit for the same degree of visualization, potentially increasing patient discomfort.

Prior to hysteroscopy, the cervix and vagina are cleaned with a small-diameter swab dipped in povidone-iodine or chlorhexidine gluconate in the case of allergies. One or two 1,000-cc bags of saline inserted into pressure bags are attached to Y-type tubing. (A diagnostic procedure rarely will require two bags.) I spread the labia initially while guiding the scope into the posterior fornix of the vagina. If the leakage of fluid causes inadequate distension of the vaginal walls, I will gently pinch the labia together with gauze.

I then gently pull back the scope and manipulate it posteriorly to visualize the external cervical os anteriorly. The hysteroscope may then be introduced through the cervical os, endocervical canal, and uterine cavity, with care taken so that the instrument does not rub against the cervix or the uterine tissue and cause trauma, pain, and bleeding. The uterus will progressively align with the cervix and vagina, thereby eliminating the need for a tenaculum to straighten the uterine axis.

Fluid monitoring is important, especially during operative hysteroscopy. In my practice, a nurse watches inflow and outflow amounts while I explain what I am doing and visualizing. Some patients like to be able to view the surgery, so I am always ready to tilt the screen accordingly.

The economics

How do you know if office hysteroscopy is right for you? Your own surgical skill and the skills of your staff, who must be trained to handle and sterilize equipment and to consistently assist you, are major factors, as is ensurance of a return on your investment.

One manufacturer contacted for this Master Class lists the price of a complete office tower (light source, camera, and monitor) at approximately $9,700 and the price of a rigid hysteroscope, sheath, and hand instruments at about $6,300. A complete setup for office hysteroscopy, including a standard operative (rigid) hysteroscope, should therefore cost between $15,000 and $17,000. Companies also offer leasing options for about $300-400/month.

Flexible hysteroscopes cost about $6,000 more, which prompts many gynecologic surgeons to focus their investment on a rigid scope that can be used for both diagnostic and therapeutic procedures. Disposables cost $10 or less, and $40-50 or less, for each diagnostic and operative hysteroscopy, respectively.

A look at the Medicare Relative Value Units (RVUs) – a key component of the Medicare reimbursement system and a standard for many payers in determining compensation – shows higher reimbursement for quite a few hysteroscopic codes when these procedures are performed in the office.

Total RVUs have three components:

1. Physician work, including time and the technical skill and intensity of effort it takes to perform a service or procedure.

2. Practice expenses, such as rent, equipment and supplies, and nonphysician salaries.

3. Malpractice insurance premiums.

Each component is multiplied by a factor that accounts for geographic cost variations, and each total RVU is multiplied by a dollar amount known as the conversion factor.

Practice expense (PE) RVUs for services provided in a “facility” (e.g., hospital or outpatient clinic) are often lower than office-based PE RVUs for the same services. Hysteroscopy is no exception. The PE RVU value for diagnostic hysteroscopy performed in the office, for instance, is approximately 5 units, compared with 1.64 units for diagnostic hysteroscopy performed in a facility.

Information on hysteroscopic procedures, and their associated RVUs, on geographic practice cost indices and on pricing, can be accessed using Medicare’s Physician Fee Schedule lookup tool (www.cms.gov/apps/physician-fee-schedule/overview.aspx).

This tool is useful for calculating returns on investment. According to national payment amounts listed in August, a diagnostic hysteroscopy performed in the office will earn an average of $315.08 vs. $192.27 for each case performed in the hospital. If you perform 12 such procedures a year, that’s about $3,781 in the office, compared with $2,307 in the hospital.

This difference alone might not be worth an investment of $15,000 or more, but if you anticipate performing additional procedures with higher margins and higher reimbursement, such as 12 thermal endometrial ablations a year in combination with diagnostic hysteroscopy (which, according to the Medicare national fee schedule averages would earn $15,962 in the office vs. $4,971 in the hospital), or 12 Essure tubal occlusions ($22,595 vs. $5,263), the investment will look more favorable.

And if your patients are largely privately insured, your return on investment will occur much more quickly. In metropolitan Chicago, Blue Cross Blue Shield is reimbursing in-office diagnostic hysteroscopy at approximately $568, hysteroscopic ablations at $3,844, and Essure tubal occlusions at $3,885.

In addition to reimbursement levels, it’s important to consider the efficiencies of in-office hysteroscopy. You can perform an annual exam while the assistant sets up the room and greets each patient, for instance, or see another established patient while the assistant discharges your patient and turns the room over. Our patients, in turn, benefit from increased accessibility, with less time spent away from work or family, as well as more familiarity and comfort and reduced out-of-pocket expenses.

Transitioning to in-office hysteroscopy need not be daunting: The setup is relatively simple and does not require an operating suite, just a dedicated exam room. And the need for premedication and local anesthesia can be low, particularly when a vaginoscopic approach to hysteroscopy is employed. For most gynecologic surgeons, the necessary skills and comfort levels fall into place after only a few vaginoscopic procedures.

A vaginoscopic approach avoids the use of a vaginal speculum or cervical tenaculum, significantly decreasing discomfort or pain. Not using these instruments is the only difference between this and traditional hysteroscopy. It is a less invasive approach that is much more tolerable for patients. And for the surgeon, it can be easier and quicker and provides equally good visualization without any impairment in cervical passage.

Described in the literature as far back as the 1950s, vaginoscopy has its roots in the pediatric/adolescent population, where it was used for the removal of foreign bodies and evaluation of the vagina and external cervical os.

More recently, Stefano Bettocchi, MD, and Luigi Selvaggi, MD, in Italy were the first to describe a vaginoscopic approach to hysteroscopy for evaluating the endocervical canal and uterine cavity.

In a series of papers from 1997 to 2004, Dr. Bettocchi and Dr. Selvaggi documented their efforts to improve patient tolerance during diagnostic hysteroscopies. When they used both the speculum and tenaculum in 163 patients, with local anesthesia, 8% reported severe pain, 11% reported moderate pain, and 69% reported mild pain. Only 12% reported no discomfort. With speculum use only, and no anesthesia, in 308 patients, none reported severe pain, 2% reported moderate pain, 32% reported mild pain, and 66% reported no discomfort. When neither instrument was used (again, no anesthesia), patient discomfort was nearly eliminated: In 680 procedures, patients had a 96% no-discomfort rate (J Am Assoc Gynecol Laparosc. 1997 Feb;4[2]:255-8; Curr Opin Obstet Gynecol. 2003 Aug;15[4]:303-8; Obstet Gynecol Clin North Am. 2004 Sep;31[3]:641-54, xi).

Since then, research has affirmed the differences in patient tolerance and has shown that there is no significant difference between traditional and vaginoscopic hysteroscopy in the rate of procedure failure (0%-10%).

In my practice, in addition to vaginal or cervical examination and evaluation of the uterine cavity, I utilize a vaginoscopic approach to perform minor therapeutic and operative procedures such as biopsies, polypectomies, tubal occlusion using the Essure system, and removal of lost intrauterine devices. I can assess infertility, trauma, abnormal uterine bleeding, and mesh erosion, and provide pre- and postsurgical evaluations. In all of these cases, I use minimal premedication and only rarely need any local anesthetic and/or sedation.

Instrumentation and technique

There are a variety of hysteroscopes available on the market, from single-channel flexible diagnostic hysteroscopes that are 3 mm to 4 mm in diameter, to “see-and-treat” operative hysteroscopes that are rigid and have various diameters and camera lens angles.

A hysteroscope with a 5.5-mm outer diameter works well for a vaginoscopic approach that avoids cervical dilation. Accessory instrumentation includes semirigid 5 Fr 35-cm–long biopsy forceps, scissors, and alligator forceps.

In timing the procedure, our main goal is a thin uterine lining. This can be achieved by scheduling the procedure during the early proliferative phase of the menstrual cycle or by using a gonadotropin-releasing hormone agonist or a transdermal or transvaginal contraceptive medication.

By far the most important element of pain control and analgesia is the time spent with each patient to thoroughly discuss the experience of hysteroscopy and to set expectations about what she will hear, see, and feel. An unexpected experience can worsen anxiety, which in turn can worsen pain. If everything is as familiar and relaxed as possible, there will be little need for analgesia.

I tell patients in preprocedure counseling that the distention of the uterine walls usually causes some cramping, and that NSAIDs can minimize this cramping. In rare cases, when a patient is very worried about her pain tolerance, I will prescribe diazepam. However, many of my patients opt to do nothing other than take ibuprofen. On a case-by-case basis, you can determine with your patient what type and level of analgesia and preprocedure medication will be best.

Paracervical blocks are an option for some surgical patients, but I advise my patients to move forward without the block and assure them that it can be administered later if needed. Thus far, I’ve never proceeded with a paracervical block. There are other methods and sites for introducing local anesthesia, including intracervical, by injection or topical, or topical intracavitary techniques. Nevertheless, it is unclear from randomized controlled trials whether local anesthesia is effective. Trials of paracervical blocks similarly have had inconsistent outcomes.

I do commonly premedicate patients – mainly nulliparous patients and postmenopausal patients – with misoprostol, which softens the cervix and facilitates an easier entry of the hysteroscope into the cervix.

Published studies on misoprostol administration before hysteroscopy have had mixed results. A Cochrane review from 2015 concluded there is moderate-quality evidence in support of preoperative ripening with the agent, while another meta-analysis also published in 2015 concluded that data are poor and do not support its use. Recently, however, there appear to be more supportive studies demonstrating or suggesting that misoprostol is effective in reducing discomfort.

Patient discomfort is also minimized when there is little manipulation of the hysteroscope. Scopes that are angled (12, 25, or 30 degrees) allow optimal visualization with minimal movement; the scope can be brought to the midline of the uterine cavity and the light cord rotated to the 3:00 and 9:00 o’clock positions to enable visualization of the cornu. A 0-degree scope, on the other hand, must be manipulated quite a bit for the same degree of visualization, potentially increasing patient discomfort.

Prior to hysteroscopy, the cervix and vagina are cleaned with a small-diameter swab dipped in povidone-iodine or chlorhexidine gluconate in the case of allergies. One or two 1,000-cc bags of saline inserted into pressure bags are attached to Y-type tubing. (A diagnostic procedure rarely will require two bags.) I spread the labia initially while guiding the scope into the posterior fornix of the vagina. If the leakage of fluid causes inadequate distension of the vaginal walls, I will gently pinch the labia together with gauze.

I then gently pull back the scope and manipulate it posteriorly to visualize the external cervical os anteriorly. The hysteroscope may then be introduced through the cervical os, endocervical canal, and uterine cavity, with care taken so that the instrument does not rub against the cervix or the uterine tissue and cause trauma, pain, and bleeding. The uterus will progressively align with the cervix and vagina, thereby eliminating the need for a tenaculum to straighten the uterine axis.

Fluid monitoring is important, especially during operative hysteroscopy. In my practice, a nurse watches inflow and outflow amounts while I explain what I am doing and visualizing. Some patients like to be able to view the surgery, so I am always ready to tilt the screen accordingly.

The economics

How do you know if office hysteroscopy is right for you? Your own surgical skill and the skills of your staff, who must be trained to handle and sterilize equipment and to consistently assist you, are major factors, as is ensurance of a return on your investment.

One manufacturer contacted for this Master Class lists the price of a complete office tower (light source, camera, and monitor) at approximately $9,700 and the price of a rigid hysteroscope, sheath, and hand instruments at about $6,300. A complete setup for office hysteroscopy, including a standard operative (rigid) hysteroscope, should therefore cost between $15,000 and $17,000. Companies also offer leasing options for about $300-400/month.

Flexible hysteroscopes cost about $6,000 more, which prompts many gynecologic surgeons to focus their investment on a rigid scope that can be used for both diagnostic and therapeutic procedures. Disposables cost $10 or less, and $40-50 or less, for each diagnostic and operative hysteroscopy, respectively.

A look at the Medicare Relative Value Units (RVUs) – a key component of the Medicare reimbursement system and a standard for many payers in determining compensation – shows higher reimbursement for quite a few hysteroscopic codes when these procedures are performed in the office.

Total RVUs have three components:

1. Physician work, including time and the technical skill and intensity of effort it takes to perform a service or procedure.

2. Practice expenses, such as rent, equipment and supplies, and nonphysician salaries.

3. Malpractice insurance premiums.

Each component is multiplied by a factor that accounts for geographic cost variations, and each total RVU is multiplied by a dollar amount known as the conversion factor.

Practice expense (PE) RVUs for services provided in a “facility” (e.g., hospital or outpatient clinic) are often lower than office-based PE RVUs for the same services. Hysteroscopy is no exception. The PE RVU value for diagnostic hysteroscopy performed in the office, for instance, is approximately 5 units, compared with 1.64 units for diagnostic hysteroscopy performed in a facility.

Information on hysteroscopic procedures, and their associated RVUs, on geographic practice cost indices and on pricing, can be accessed using Medicare’s Physician Fee Schedule lookup tool (www.cms.gov/apps/physician-fee-schedule/overview.aspx).

This tool is useful for calculating returns on investment. According to national payment amounts listed in August, a diagnostic hysteroscopy performed in the office will earn an average of $315.08 vs. $192.27 for each case performed in the hospital. If you perform 12 such procedures a year, that’s about $3,781 in the office, compared with $2,307 in the hospital.

This difference alone might not be worth an investment of $15,000 or more, but if you anticipate performing additional procedures with higher margins and higher reimbursement, such as 12 thermal endometrial ablations a year in combination with diagnostic hysteroscopy (which, according to the Medicare national fee schedule averages would earn $15,962 in the office vs. $4,971 in the hospital), or 12 Essure tubal occlusions ($22,595 vs. $5,263), the investment will look more favorable.

And if your patients are largely privately insured, your return on investment will occur much more quickly. In metropolitan Chicago, Blue Cross Blue Shield is reimbursing in-office diagnostic hysteroscopy at approximately $568, hysteroscopic ablations at $3,844, and Essure tubal occlusions at $3,885.

In addition to reimbursement levels, it’s important to consider the efficiencies of in-office hysteroscopy. You can perform an annual exam while the assistant sets up the room and greets each patient, for instance, or see another established patient while the assistant discharges your patient and turns the room over. Our patients, in turn, benefit from increased accessibility, with less time spent away from work or family, as well as more familiarity and comfort and reduced out-of-pocket expenses.

Purpose: Extract, retrieve, and validate clinical lab information from the VA Corporate Data Warehouse (CDW).

Background: CDW clinical lab information provide a unique opportunity to assess real world cancer treatment effectiveness and safety with higher granularity and validity compared to administrative data. Unfortunately, there is significant heterogeneity in how this information is encoded across time and geography. Various efforts have been made to clean these data and provide a consistent and reliable mapping; however, the availability and validity of these efforts also vary across lab concepts. This presents a significant barrier to utilization of CDW clinical lab information in comparative effectiveness research.

Methods: We defined a conceptual framework for retrieval of lab information 5 features: Logical Observation Identifiers Names and Codes (LOINC) codes, test names, topography, unit, and unit reference ranges. This was then implemented as a framework in R comprised of 7 discrete modules. Each module corresponds to a defined task in the conceptual framework: Concept -> LOINC/test name -> cleaned LOINC/test name -> LOINC/test name internal identifier -> fact information retrieval -> topography selection -> unit and reference range cleaning and harmonization. Each module has a defined input and output allowing implementation transparency, reproducibility, and flexibility.

Results: Using the CLIR framework, we retrieved peripheral blood total white count of patients with hematologic malignancies. In a cohort of about 300,000 patients diagnosed and or treated for a hematologic malignancy in the VHA between 2001-2016, we identified ~ 11x10^6 potential total WBC count based on LOINC codes and lab test name. Of those, ~ 9x106 were mappable to the correct topography, and the overwhelming majority of which (99%) were mappable to a harmonized unit and reference range.

Conclusion: The CLIR framework provides a conceptual framework and an implementation in R for clinical lab information retrieval from the VA CDW. Future efforts will entail refining the methodology across multiple data domains and comparing CLIR output with other ongoing efforts aimed at cleaning and harmonization of clinical lab data in the CDW.

BRAF inhibitor (BRAFi) combined with MEK inhibitor (MEKi) are used to treat melanomas harboring (V600E) mutation. While response is high, the majority of them relapsed. We found novel mechanisms to treat BRAFi resistant (BR) patients.

Five BR cells were established from known BRAF mutant cell lines A375, MEL-1220, A2058, UACC-62, and SKMEL28 by long-term exposure to BRAFi. These BR cells are hypersensitive to ADI-PEG20, an enzyme which degrades arginine to citrulline. ADI-PEG20 treatment resulted in 10-30% increase in apoptosis (Annexin V/PI) in BR cells compared to their paternal cells. The mechanisms involved are as follows: All BR cells express very low levels or do not express argininosuccinate synthetase (ASS, a key enzyme to generate arginine from citrulline) and also have attenuated glucose uptake. Thus, these BR cells rely primarily on exogenous arginine. Importantly, their ability to undergo autophagy upon nutritional stress is also impaired. The underlying mechanism for low levels of ASS is due to diminished c-Myc expression,a positive regulator for ASS. Additionally, AMPK-α 1, which governed autophagy and glucose uptake, was attenuated in BR cells. Overexpression of AMPK-α 1 using plasmid transfection in A2058BR and MEL-1220BR cells rescued 8-28% ADI-PEG20-induced apoptosis and enhanced autophagosome formation. Conversely, knockdown of AMPK-α 1 significantly enhanced ADI-PEG20-reduced cell viability in A2058 and MEL-1220 cells through attenuation of autophagy and glucose uptake. This is evidenced by decreased GLUT1 and LC3-II expression, and low activity of 2-NBDG uptake seen in BR cells. BMR (BRAF and MEK inhibitor) resistant cells also shared similar biochemical changes. Immunohistochemical staining further confirmed lower levels of ASS and AMPK-α 1 in A2058BR, BMR and in tumor tissues from 10 BR patients relative to their parental counterparts (average H-scores of ASS and AMPK in parental tissues vs. BR tissues are 58.2 vs. 7.8, and 146 vs. 78.3, respectively, P < 0.03). Importantly, these findings also apply to cell lines and tumor samples from patients who failed both BRAF and MEK inhibitor.

In summary, our data suggest that attenuated AMPK-α 1 mediated autophagy and glucose uptake and decreased c-Myc mediated ASS re-expression sensitize BR cells to arginine deprivation, and can be used as salvage therapy for BR patients.

Expires June 30, 2017

VITALSKey clinical point: Clinicians may wish to discuss the option of hysterectomy at the time of salpingo-oophorectomy in women with deleterious BRCA1 mutations.
Major finding: Among women with BRCA1 but not BRCA2 mutations there was increased risk for serous/serous-like endometrial carcinomas.
Data source: Prospective multicenter follow-up study of 1,083 women with BRCA mutations who underwent salpingo-oophorectomy without hysterectomy.
Disclosures: The study was supported by grants from the Department of Defense, National Institutes of Health, and public and private foundations. Coauthor Robert Soslow, MD, disclosed consulting for EMD Serono. No others reported conflicts of interest. The editorialists reported no conflicts of interest related to the study.

To take the posttest, go to: http://bit.ly/2sIyLNI
Expires July 14, 2017

VITALSKey clinical point: The combination of a topical steroid and topical vitamin D is marginally better but with a similar safety profile to steroids alone as a treatment for psoriasis on the scalp.
Major finding: The combination of a topical steroid and vitamin D showed a small but statistically significant advantage over steroids alone, and a greater advantage over vitamin D alone.
Data source: A systematic review of 59 randomized controlled studies in 11,561 patients.
Disclosures: The study was supported by the Universidade Federal de São Paulo, Brazil; the Universidade Federal do Rio Grande do Norte, Brazil; and the National Institute for Health Research, United Kingdom. Six authors and one clinical referee declared speakers' fees, research grants, and funding from the pharmaceutical industry. One author had no conflicts of interest to disclose.

3. Study Finds Emergence of Azithromycin-resistant Gonorrhea

To take the posttest, go to: http://bit.ly/2u1nMmb
Expires July 16, 2017

VITALSKey clinical point:Resistance to azithromycin is emerging among patients diagnosed with gonorrhea.
Major finding: Among patients with gonorrhea, resistance to azithromycin increased from 0.6% in 2013 to 2.5% in 2014, predominantly in the Midwest.
Data source: An analysis of 5,093 Neisseria gonorrhoeae isolates from 27 clinics as part of the CDC's Gonococcal Isolate Surveillance Project.
Disclosures: The researchers had no financial disclosures.

4. Statins Improve Ovarian Cancer Survival

To take the posttest, go to: http://bit.ly/2t6swCF
Expires June 16, 2017

VITALSKey clinical point: The risk of all-cause mortality in ovarian cancer patients on statin therapy was reduced by one-third.
Major finding: Mean survival in a large cohort of women with stage III ovarian cancer was 5.8 months longer among those on statin therapy.
Data source: A retrospective study of 1,510 women diagnosed with epithelial ovarian cancer during 2007-2009.
Disclosures: Dr. Vogel reported having no financial conflicts regarding this study, conducted without commercial support.

5. Common Surgeries Linked to Chronic Opioid Use Among Opioid-naive Patients

To take the posttest, go to: http://bit.ly/2ub9fFg
Expires June 18, 2017

VITALSKey clinical point: Common surgeries increase the risk of chronic opioid use in opioid-naive adults, especially among those using antidepressants or benzodiazepines before their operations, and those with substance abuse histories.
Major finding: After adjustment for potential confounders, knee replacement increased the risk fivefold; open cholecystectomy almost fourfold; and total hip replacement and simple mastectomy almost threefold.
Data source: Insurance claims of more than 18 million people.
Disclosures: The authors had no disclosures. The work was funded in part by the Foundation for Anesthesia Education and Research and the Anesthesia Quality Institute. Claims data came from MarketScan (Truven Health Analytics).

“Increasingly, we are not having faculty who are going up for promotion and reliably running into challenges around mentorship, national reputation, and having a network outside of their local hospital that is critical for advancement,” says lead author Ethan Cumbler, MD, FHM, FACP, of the Department of Medicine at the University of Colorado School of Medicine. “Hospital medicine as a movement is built on a foundation of innovation, and so as a specialty, we have a mandate to not only innovate but to disseminate those innovations.”

The model of the visiting professorship described in the paper takes midcareer academic hospitalists and provides an infrastructure for reciprocal faculty exchanges. This provides a forum to increase professional networks.

“We found that both junior faculty and our visiting professors saw value in advancing those goals,” Dr. Cumbler says. “We also saw evidence of the spread of ideas and new shared scholarship derived from having these reciprocal visits.”

This has model relevance for nonacademic hospitals, too. For example, it’d be useful for hospital medicine groups to share ideas with one another, Dr. Cumbler says.

“This is a simple structure, but it’s just like a small pebble thrown into a large body of water can create ripples which affect distant shores—sometimes it’s very simple concepts that are worth pursuing,” he says.
