Combat Dermatology: The Role of the Deployed Army Dermatologist
Military dermatologists complete their residency training at 1 of 3 large military medical centers across the country: Walter Reed National Military Medical Center (Bethesda, Maryland), San Antonio Military Health System (San Antonio, Texas), or Naval Medical Center San Diego (San Diego, California). While in training, army dermatology residents in particular fall under the US Army Medical Command, or MEDCOM, which provides command and control of the army’s medical, dental, and veterinary treatment facilities. Upon graduating from residency, army dermatologists often are stationed with MEDCOM units but become eligible for deployment with US Army Forces Command (FORSCOM) units to both combat and noncombat zones depending on each individual FORSCOM unit’s mission.
The process by which dermatologists and other army physicians are tasked to a deploying FORSCOM unit is referred to as the Professional Filler System, or PROFIS, which was designed to help alleviate the financial cost and specialty skill degradation of having a physician assigned to a FORSCOM unit while not deployed.1 In general, the greater the amount of time that an army medical officer has not been deployed, the more likely they are to be selected for deployment with a FORSCOM unit. For the army dermatologist, deployment often comes shortly after completing residency or fellowship.
In this article, we review the various functions of the deployed dermatologist and also highlight the importance of maintaining basic emergency medical skills that could be generalized to the civilian population in case of local or national emergencies.
THE FIELD SURGEON
With rare exceptions, the US Army does not deploy dermatologists for their expertise in diagnosing and managing cutaneous diseases. Typically, a dermatologist will be assigned to a FORSCOM unit in the role of field surgeon. Other medical specialties including emergency medicine, family practice, internal medicine, pediatrics, and obstetrics and gynecology also are eligible for deployment as field surgeons.2 Field surgeons typically are assigned to a battalion-sized element of 300 to 1000 soldiers and are responsible for all medical care rendered under their supervision. Duties include combat resuscitation, primary care services, preventive medicine, medical training of battalion medical personnel, and serving as the medical adviser to the battalion commander.1 In some instances, a field surgeon will be stationed at a higher level of care co-located with a trauma surgeon; in those cases, the field surgeon also may be expected to assist in trauma surgery cases.
ARMY DEPLOYMENT MEDICAL SYSTEM
To better understand the responsibilities of a field surgeon, it is important to discuss the structure of the army’s deployment medical system. The US Military, including the army, has adopted a system of “roles” that have specific requirements regarding their associated medical capabilities.3 There are 4 roles designated within the army. Role 1 facilities are known as battalion aid stations (BASs).
Role of the Field Surgeon
Within the broader structure of the army, approximately 5 battalions (each composed of 300 to 1000 soldiers) comprise a single brigade combat team. Role 1 medical facilities typically have a single battalion surgeon assigned to them. Field surgeons most commonly serve in this battalion surgeon position. Additionally, Role 2 facilities may have slots for up to 2 battalion surgeons; however, field surgeons are less commonly tasked with this assignment.1 Occasionally, in one author’s (N.R.M.) personal experience, these roles are more fluid than one might expect. A field surgeon tasked initially with a Role 1 position may be shifted to a Role 2 assignment on an as-needed basis. This ability for rapid change in roles and responsibilities underscores the need for a fluid mind-set and thorough predeployment training for the field surgeon.
PREDEPLOYMENT TRAINING
As one might expect, dermatologists who have just graduated residency or fellowship are unlikely to have honed their trauma support skills to the degree needed to support a deployed battalion actively engaging in combat. Fortunately, there are many opportunities for military dermatologists to practice these skills prior to joining their FORSCOM colleagues. The initial exposure to trauma support comes during medical internship at the mandatory Combat Casualty Care Course (C4), an 8-day program designed to enhance the operational medical readiness and predeployment trauma training skills of medical officers.4 The C4 program includes 3 days of classroom training and 5 days of intensive field training. During C4, medical officers become certified in Advanced Trauma Life Support, a 3-day course organized by the American College of Surgeons.5 This course teaches medical officers how to quickly and judiciously triage, treat, and transport patients who have sustained potentially life-threatening traumas.
The next components of predeployment training, Tactical Combat Casualty Care and Tactical Combat Medical Care, occur in the months to weeks immediately preceding deployment.1,6 Tactical Combat Casualty Care prepares participants in the initial stabilization of trauma to occur at the point of injury.6 Tactical Combat Casualty Care principles generally are employed by medics (enlisted personnel trained in point-of-care medical support) rather than physicians; however, these principles are still critical for medical officers to be aware of when encountering severe traumas.6 In addition, the physician is responsible for ensuring his/her medics are fully trained in Tactical Combat Casualty Care. Tactical Combat Medical Care is geared more toward the direct preparation of medical officers. During the 5-day course, medical officers learn the gold standard for trauma care in both the classroom and in hands-on scenarios.1 This training not only allows medical officers to be self-sufficient in providing trauma support, but it also enables them to better maintain quality control of the performance of their medics continuously throughout the deployment.1
DEPLOYMENT RESPONSIBILITIES
Dermatologists who have completed the above training typically are subsequently deployed as field surgeons to a Role 1 facility. Field surgeons are designated as the officer in charge of the BAS and assume the position of medical platoon leader. A field surgeon usually will have both a physician assistant and a field medical assistant/medical plans officer (MEDO) to assist in running the BAS. The overarching goal of the field surgeon is to maintain the health and readiness of the battalion. In addition to addressing the day-to-day health care needs of individual soldiers, a field surgeon is expected to attend all staff meetings, advise the commander on preventative health and epidemiological trends, identify the scope of practice of the medics, ensure the BAS is prepared for mass casualties, and take responsibility for all controlled substances.
To illustrate the value that the properly trained dermatologist can provide in the deployed setting, we will outline field surgeon responsibilities and provide case examples of the first-hand experiences of one of the authors (N.R.M.) as a Role 2 officer in charge and field surgeon. The information presented in the case examples may have been altered to ensure continued operational security and out of respect to US servicemembers and coalition forces while still conveying important learning points.
Sick Call
In the deployed environment, military sick call functions as an urgent care center that is open continuously and serves the active-duty population, US government civilians and contractors, and coalition forces. In general, the physician assistant should treat approximately two-thirds of sick call patients under the supervision of the field surgeon, allowing the field surgeon to focus on his/her ancillary duties and ensure overall medical supervision of the unit. As a safeguard, patients with more than 2 visits for the same concern must be evaluated by the field surgeon. Sick call concerns range from minor traumas and illnesses to much more serious disease processes and injuries (as outlined in Medical Emergencies). As a field surgeon, it is critical to track disease nonbattle illnesses to ensure medical readiness of the unit. In the deployed environment, close quarters and austere environments commonly lend themselves to gastrointestinal illnesses, respiratory diseases, heat injuries, vector-borne diseases, and sexually transmitted infections.
Case Examples
During an 8-month deployment in Afghanistan, one of the authors (N.R.M.) provided or assisted in the care of more than 2300 routine sick call appointments, or approximately 10 patients per day. Epidemiology of disease was tracked, and the condition of the unit was presented daily to the battalion commander for consideration in upcoming operations. The top 5 most common categories of diagnoses included musculoskeletal injuries, gastrointestinal diseases, dermatologic concerns (eg, dermatitis, bacterial infections [cellulitis/abscess], fungal infections, arthropod assault, abrasions, lacerations, verruca vulgaris), respiratory illnesses, and mental health care, respectively. Maintaining a familiarity with general medicine is critical for the military dermatologist, and an adequate medical library or access to online medical review sources is critical for day-to-day sick call.
Medical Emergencies
In the event of a more serious injury or illness, a Role 1 BAS has very little capability in performing anything beyond the most basic interventions. Part of the art of being an effective field surgeon lies in stabilization, triage, and transport of these sometimes very ill patients. Both the decision to transport to a higher level of care (eg, Role 2 or 3 facility) as well as selection of the means of transportation falls on the field surgeon. The MEDO plays an essential role in assisting in the coordination of the transfer; however, the responsibility ultimately falls on the field surgeon.1,6 The field surgeon at the Role 2 BAS may be expected to perform more advanced medical and surgical interventions. More advanced pharmacotherapies include thrombolytics, antivenin, and vasopressors. Some procedural interventions include intubations, central lines, and laceration repairs. The Role 2 BAS has the capability to hold patients for up to 72 hours.
Case Examples
Specific conditions one of the authors (N.R.M.) treated include heat injury, myocardial infarction, disseminated tuberculosis, appendicitis, testicular torsion, malaria, suicidal ideation, burns, and status epilepticus. Over 8 months, the Role 2 BAS received 91 medical emergencies, with 53 necessitating evacuation to a higher level of care. Often, the more serious or rare conditions presented in the foreign contractor and coalition force populations working alongside US troops.
In one particular case, a 35-year-old man with an electrocardiogram-confirmed acute ST-segment elevation myocardial infarction was administered standard therapy consisting of intravenous morphine, oxygen, sublingual nitroglycerin, an angiotensin-converting enzyme inhibitor, and a beta-blocker. Given the lack of a cardiac catheterization laboratory at the next highest level of care as well as a low suspicion for aortic dissection (based on the patient’s history, physical examination, and chest radiograph), fibrinolysis with tenecteplase was performed in the deployed environment. After a very short observation for potential hemorrhage, the patient was then evacuated to the Role 3 hospital, where he made a near-complete recovery. Preparation with advanced cardiac life support courses and a thorough algorithmic review of the 10 most common causes of presentation to the emergency department helped adequately prepare the dermatologist to succeed.
Trauma Emergencies
The same principles of triage and transport apply to trauma emergencies. Mass casualties are an inevitable reality in combat, so appropriate training translating into efficient action is essential to ensure the lowest possible mortality. This training and the actions that stem from it are an additional responsibility that the field surgeon must maintain. During deployment, continued training organized by the field surgeon could quite literally mean the difference between life and death. In addition to the organizational responsibilities, field surgeons should be prepared to perform initial stabilization in trauma patients, including application of tourniquets, establishment of central lines, reading abdominal ultrasounds for free fluid, placement of chest tubes, intubation, and ventilator management. The Joint Trauma System Clinical Practice Guidelines also offer extensive and invaluable guidance on the most up-to-date approach to common trauma conditions arising in the deployed environment.7 At the Role 2 level, the field surgeon also must be prepared to coordinate ancillary services, manage the Role 2/forward surgical team intensive care unit, and serve as first assist in the operating room, as needed (Figure 2).
Case Examples
One of the authors (N.R.M.) assisted or provided care in approximately 225 trauma cases while deployed. A mass casualty event occurred, in which the Role 2 BAS received 34 casualties; of these casualties, 11 were immediate, 10 were delayed, 11 were minimal, and 2 were expectant. Injury patterns included mounted and dismounted improvised explosive device injuries (eg, blast, shrapnel, and traumatic brain injuries) as well as gunshot wounds. Direct care was provided for 13 casualties, including 10 abdominal ultrasound examinations for free fluid, placement of 2 chest tubes, 1 intubation, establishment of 3 central lines, and first-assisting 1 exploratory laparotomy. Of the casualties, 22 were evacuated to the Role 3 hospital, 8 were dispositioned to a coalition hospital, 2 were returned to active duty, and 2 died due to their injuries. The military trauma preparation as outlined in the predeployment training can help adequately prepare the military dermatologist to assist in these cases.
Ancillary Services
An important part of the efficacy of initial evaluation and stabilization of both medical and traumatic emergencies involves expedited laboratory tests, imaging, and the delivery of life-saving blood products to affected patients. The field surgeon is responsible for the readiness of these services and may play a critical role in streamlining these tasks for situations where a delay in care by minutes can be lethal. The MEDO assists the field surgeon to ensure the readiness of the medical equipment, and the field surgeon must ensure the readiness of the medics and technicians utilizing the equipment. In a deployed environment, only a finite amount of blood products may be stored. As a result, the design and implementation of an efficient and precise walking blood bank is critical. To help mitigate this issue, servicemembers are prescreened for their blood types and bloodborne illnesses. If a situation arises in which whole blood is needed, the prescreened individuals are screened again, and their blood is collected and transfused to the patient under the supervision of the physician. This task is critical in saving lives, and this process is the primary responsibility of the field surgeon.
Case Example
A 37-year-old man presented to the BAS with abdominal and pelvic gunshot wounds, as well as tachycardia, rapidly decreasing blood pressure, and altered consciousness. An exploratory laparotomy was performed to look for the sources of bleeding. The patient’s blood type was confirmed with a portable testing kit. Due to the injury pattern and clinical presentation, a call was immediately placed to begin screening and preparing servicemembers to donate blood for the walking blood bank. As expected, the Role 2 supply of blood products was exhausted during the exploratory laparotomy. With servicemembers in place and screened, an additional 12 units of whole blood were collected and administered in a timely fashion. The patient was stabilized and transported to the next highest level of care. Due to the process optimization performed by the laboratory team, whole-blood transfusions were ready within an average of 22 minutes, well ahead of the 45-minute standard of care.
Operating Room First Assist
If a field surgeon is stationed at a Role 2 BAS with a forward surgical team, he/she may be required to adopt the role of operating room first assist for the trauma surgeon or orthopedic surgeon on the team, which is especially true for isolated major traumas when triage and initial stabilization measures for multiple patients are of less concern. Dermatologists receive surgical training as part of the Accreditation Council for Graduate Medical Education requirements to graduate residency, making them more than capable of surgical assisting when needed.8 In particular, dermatologists’ ability to utilize instruments appropriately and think procedurally as well as their skills in suturing are helpful.
Case Example
A 22-year-old man with several shrapnel wounds to the abdomen demonstrated free fluid in the left lower quadrant. The field surgeon (N.R.M.) assisted the trauma surgeon in opening the abdomen and running the bowel for sources of bleeding. The trauma surgeon identified the bleed and performed a ligation. The patient was then packed, closed, and prepared for transfer to a higher level of care.
Preventive Medicine
As a result of the field surgeon being on the front line of medical care in an austere environment, implementation of preventive medicine practices and disease pattern recognition are his/her responsibility. Responsibilities may include stray animal euthanasia due to prevalence of rabies, enforcement of malaria prophylaxis, medical training and maintenance of snake antivenin, and assistance with other local endemic disease. The unique skill set of dermatologists in organism identification can further bolster the speed with which vector-borne diseases are recognized and prevention and treatment measures are implemented.
Case Example
As coalition forces executed a mission in Afghanistan, US servicemembers began experiencing abdominal distress, chills, fevers (temperature >40°C), debilitating headaches, myalgia, arthralgia, and tachycardia. Initially, these patients were evacuated to the Role 2 BAS, hindering the mission. Upon inspection, patients had numerous bug bites; one astute soldier collected the arthropod guilty of the assault and brought it to the aid station. Upon inspection, the offender was identified as the Phlebotomus genus of sandflies, organisms that are well known to dermatologists as a cause of leishmaniasis. Clinical correlation resulted in the presumed diagnosis of Pappataci fever, and vector-borne disease prevention measures were then able to be further emphasized and implemented in at-risk areas, allowing the mission to continue.9 Subsequent infectious disease laboratory testing confirmed the Phlebovirus transmitted by the sandfly as the underlying cause of the illness.
CONCLUSION
The diverse role of the field surgeon in the deployed setting makes any one specialist underprepared to completely take on the role from the outset; however, with appropriate and rigorous trauma training prior to deployment, dermatologists will continue to perform as invaluable assets to the US military in conflicts now and in the future.

Clinical correlation resulted in the presumed diagnosis of Pappataci fever, and vector-borne disease prevention measures were then able to be further emphasized and implemented in at-risk areas, allowing the mission to continue.9 Subsequent infectious disease laboratory testing confirmed the Phlebovirus transmitted by the sandfly as the underlying cause of the illness.
CONCLUSION
The diverse role of the field surgeon in the deployed setting makes any one specialist underprepared to completely take on the role from the outset; however, with appropriate and rigorous trauma training prior to deployment, dermatologists will continue to perform as invaluable assets to the US military in conflicts now and in the future.
Military dermatologists complete their residency training at 1 of 3 large military medical centers across the country: Walter Reed National Military Medical Center (Bethesda, Maryland), San Antonio Military Health System (San Antonio, Texas), or Naval Medical Center San Diego (San Diego, California). While in training, army dermatology residents in particular fall under the US Army Medical Command, or MEDCOM, which provides command and control of the army’s medical, dental, and veterinary treatment facilities. Upon graduating from residency, army dermatologists often are stationed with MEDCOM units but become eligible for deployment with US Army Forces Command (FORSCOM) units to both combat and noncombat zones depending on each individual FORSCOM unit’s mission.
The process by which dermatologists and other army physicians are tasked to a deploying FORSCOM unit is referred to as the Professional Filler System, or PROFIS, which was designed to help alleviate the financial cost and specialty skill degradation of having a physician assigned to a FORSCOM unit while not deployed.1 In general, the greater the amount of time that an army medical officer has not been deployed, the more likely they are to be selected for deployment with a FORSCOM unit. For the army dermatologist, deployment often comes shortly after completing residency or fellowship.
In this article, we review the various functions of the deployed dermatologist and also highlight the importance of maintaining basic emergency medical skills that could be generalized to the civilian population in case of local or national emergencies.
THE FIELD SURGEON
With rare exceptions, the US Army does not deploy dermatologists for their expertise in diagnosing and managing cutaneous diseases. Typically, a dermatologist will be assigned to a FORSCOM unit in the role of field surgeon. Other medical specialties including emergency medicine, family practice, internal medicine, pediatrics, and obstetrics and gynecology also are eligible for deployment as field surgeons.2 Field surgeons typically are assigned to a battalion-sized element of 300 to 1000 soldiers and are responsible for all medical care rendered under their supervision. Duties include combat resuscitation, primary care services, preventive medicine, medical training of battalion medical personnel, and serving as the medical adviser to the battalion commander.1 In some instances, a field surgeon will be stationed at a higher level of care co-located with a trauma surgeon; in those cases, the field surgeon also may be expected to assist in trauma surgery cases.
ARMY DEPLOYMENT MEDICAL SYSTEM
To better understand the responsibilities of a field surgeon, it is important to discuss the structure of the army’s deployment medical system. The US Military, including the army, has adopted a system of “roles” that have specific requirements regarding their associated medical capabilities.3 There are 4 roles designated within the army. Role 1 facilities are known as battalion aid stations (BASs).
Role of the Field Surgeon
Within the broader structure of the army, approximately 5 battalions (each composed of 300 to 1000 soldiers) comprise a single brigade combat team. Role 1 medical facilities typically have a single battalion surgeon assigned to them. Field surgeons most commonly serve in this battalion surgeon position. Additionally, Role 2 facilities may have slots for up to 2 battalion surgeons; however, field surgeons are less commonly tasked with this assignment.1 Occasionally, in one author’s (N.R.M.) personal experience, these roles are more fluid than one might expect. A field surgeon tasked initially with a Role 1 position may be shifted to a Role 2 assignment on an as-needed basis. This ability for rapid change in roles and responsibilities underscores the need for a fluid mind-set and thorough predeployment training for the field surgeon.
PREDEPLOYMENT TRAINING
As one might expect, dermatologists who have just graduated residency or fellowship are unlikely to have honed their trauma support skills to the degree needed to support a deployed battalion actively engaging in combat. Fortunately, there are many opportunities for military dermatologists to practice these skills prior to joining their FORSCOM colleagues. The initial exposure to trauma support comes during medical internship at the mandatory Combat Casualty Care Course (C4), an 8-day program designed to enhance the operational medical readiness and predeployment trauma training skills of medical officers.4 The C4 program includes 3 days of classroom training and 5 days of intensive field training. During C4, medical officers become certified in Advanced Trauma Life Support, a 3-day course organized by the American College of Surgeons.5 This course teaches medical officers how to quickly and judiciously triage, treat, and transport patients who have sustained potentially life-threatening traumas.
The next components of predeployment training, Tactical Combat Casualty Care and Tactical Combat Medical Care, occur in the months to weeks immediately preceding deployment.1,6 Tactical Combat Casualty Care prepares participants in the initial stabilization of trauma to occur at the point of injury.6 Tactical Combat Casualty Care principles generally are employed by medics (enlisted personnel trained in point-of-care medical support) rather than physicians; however, these principles are still critical for medical officers to be aware of when encountering severe traumas.6 In addition, the physician is responsible for ensuring his/her medics are fully trained in Tactical Combat Casualty Care. Tactical Combat Medical Care is geared more toward the direct preparation of medical officers. During the 5-day course, medical officers learn the gold standard for trauma care in both the classroom and in hands-on scenarios.1 This training not only allows medical officers to be self-sufficient in providing trauma support, but it also enables them to better maintain quality control of the performance of their medics continuously throughout the deployment.1
DEPLOYMENT RESPONSIBILITIES
Dermatologists who have completed the above training typically are subsequently deployed as field surgeons to a Role 1 facility. Field surgeons are designated as the officer in charge of the BAS and assume the position of medical platoon leader. A field surgeon usually will have both a physician assistant and a field medical assistant/medical plans officer (MEDO) to assist in running the BAS. The overarching goal of the field surgeon is to maintain the health and readiness of the battalion. In addition to addressing the day-to-day health care needs of individual soldiers, a field surgeon is expected to attend all staff meetings, advise the commander on preventative health and epidemiological trends, identify the scope of practice of the medics, ensure the BAS is prepared for mass casualties, and take responsibility for all controlled substances.
To illustrate the value that the properly trained dermatologist can provide in the deployed setting, we will outline field surgeon responsibilities and provide case examples of the first-hand experiences of one of the authors (N.R.M.) as a Role 2 officer in charge and field surgeon. The information presented in the case examples may have been altered to ensure continued operational security and out of respect to US servicemembers and coalition forces while still conveying important learning points.
Sick Call
In the deployed environment, military sick call functions as an urgent care center that is open continuously and serves the active-duty population, US government civilians and contractors, and coalition forces. In general, the physician assistant should treat approximately two-thirds of sick call patients under the supervision of the field surgeon, allowing the field surgeon to focus on his/her ancillary duties and ensure overall medical supervision of the unit. As a safeguard, patients with more than 2 visits for the same concern must be evaluated by the field surgeon. Sick call concerns range from minor traumas and illnesses to much more serious disease processes and injuries (as outlined in Medical Emergencies). As a field surgeon, it is critical to track disease nonbattle illnesses to ensure medical readiness of the unit. In the deployed environment, close quarters and austere environments commonly lend themselves to gastrointestinal illnesses, respiratory diseases, heat injuries, vector-borne diseases, and sexually transmitted infections.
Case Examples
During an 8-month deployment in Afghanistan, one of the authors (N.R.M.) provided or assisted in the care of more than 2300 routine sick call appointments, or approximately 10 patients per day. Epidemiology of disease was tracked, and the condition of the unit was presented daily to the battalion commander for consideration in upcoming operations. The top 5 most common categories of diagnoses included musculoskeletal injuries, gastrointestinal diseases, dermatologic concerns (eg, dermatitis, bacterial infections [cellulitis/abscess], fungal infections, arthropod assault, abrasions, lacerations, verruca vulgaris), respiratory illnesses, and mental health care, respectively. Maintaining a familiarity with general medicine is critical for the military dermatologist, and an adequate medical library or access to online medical review sources is critical for day-to-day sick call.
Medical Emergencies
In the event of a more serious injury or illness, a Role 1 BAS has very little capability in performing anything beyond the most basic interventions. Part of the art of being an effective field surgeon lies in stabilization, triage, and transport of these sometimes very ill patients. Both the decision to transport to a higher level of care (eg, Role 2 or 3 facility) as well as selection of the means of transportation falls on the field surgeon. The MEDO plays an essential role in assisting in the coordination of the transfer; however, the responsibility ultimately falls on the field surgeon.1,6 The field surgeon at the Role 2 BAS may be expected to perform more advanced medical and surgical interventions. More advanced pharmacotherapies include thrombolytics, antivenin, and vasopressors. Some procedural interventions include intubations, central lines, and laceration repairs. The Role 2 BAS has the capability to hold patients for up to 72 hours.
Case Examples
Specific conditions one of the authors (N.R.M.) treated include heat injury, myocardial infarction, disseminated tuberculosis, appendicitis, testicular torsion, malaria, suicidal ideation, burns, and status epilepticus. Over 8 months, the Role 2 BAS received 91 medical emergencies, with 53 necessitating evacuation to a higher level of care. Often, the more serious or rare conditions presented in the foreign contractor and coalition force populations working alongside US troops.
In one particular case, a 35-year-old man with an electrocardiogram-confirmed acute ST-segment elevation myocardial infarction was administered standard therapy consisting of intravenous morphine, oxygen, sublingual nitroglycerin, an angiotensin-converting enzyme inhibitor, and a beta-blocker. Given the lack of a cardiac catheterization laboratory at the next highest level of care as well as a low suspicion for aortic dissection (based on the patient’s history, physical examination, and chest radiograph), fibrinolysis with tenecteplase was performed in the deployed environment. After a very short observation for potential hemorrhage, the patient was then evacuated to the Role 3 hospital, where he made a near-complete recovery. Preparation with advanced cardiac life support courses and a thorough algorithmic review of the 10 most common causes of presentation to the emergency department helped adequately prepare the dermatologist to succeed.
Trauma Emergencies
The same principles of triage and transport apply to trauma emergencies. Mass casualties are an inevitable reality in combat, so appropriate training translating into efficient action is essential to ensure the lowest possible mortality. This training and the actions that stem from it are an additional responsibility that the field surgeon must maintain. During deployment, continued training organized by the field surgeon could quite literally mean the difference between life and death. In addition to the organizational responsibilities, field surgeons should be prepared to perform initial stabilization in trauma patients, including application of tourniquets, establishment of central lines, reading abdominal ultrasounds for free fluid, placement of chest tubes, intubation, and ventilator management. The Joint Trauma System Clinical Practice Guidelines also offer extensive and invaluable guidance on the most up-to-date approach to common trauma conditions arising in the deployed environment.7 At the Role 2 level, the field surgeon also must be prepared to coordinate ancillary services, manage the Role 2/forward surgical team intensive care unit, and serve as first assist in the operating room, as needed (Figure 2).
Case Examples
One of the authors (N.R.M.) assisted or provided care in approximately 225 trauma cases while deployed. A mass casualty event occurred, in which the Role 2 BAS received 34 casualties; of these casualties, 11 were immediate, 10 were delayed, 11 were minimal, and 2 were expectant. Injury patterns included mounted and dismounted improvised explosive device injuries (eg, blast, shrapnel, and traumatic brain injuries) as well as gunshot wounds. Direct care was provided for 13 casualties, including 10 abdominal ultrasound examinations for free fluid, placement of 2 chest tubes, 1 intubation, establishment of 3 central lines, and first-assisting 1 exploratory laparotomy. Of the casualties, 22 were evacuated to the Role 3 hospital, 8 were dispositioned to a coalition hospital, 2 were returned to active duty, and 2 died due to their injuries. The military trauma preparation as outlined in the predeployment training can help adequately prepare the military dermatologist to assist in these cases.
Ancillary Services
An important part of the efficacy of initial evaluation and stabilization of both medical and traumatic emergencies involves expedited laboratory tests, imaging, and the delivery of life-saving blood products to affected patients. The field surgeon is responsible for the readiness of these services and may play a critical role in streamlining these tasks for situations where a delay in care by minutes can be lethal. The MEDO assists the field surgeon to ensure the readiness of the medical equipment, and the field surgeon must ensure the readiness of the medics and technicians utilizing the equipment. In a deployed environment, only a finite amount of blood products may be stored. As a result, the design and implementation of an efficient and precise walking blood bank is critical. To help mitigate this issue, servicemembers are prescreened for their blood types and bloodborne illnesses. If a situation arises in which whole blood is needed, the prescreened individuals are screened again, and their blood is collected and transfused to the patient under the supervision of the physician. This task is critical in saving lives, and this process is the primary responsibility of the field surgeon.
Case Example
A 37-year-old man presented to the BAS with abdominal and pelvic gunshot wounds, as well as tachycardia, rapidly decreasing blood pressure, and altered consciousness. An exploratory laparotomy was performed to look for the sources of bleeding. The patient’s blood type was confirmed with a portable testing kit. Due to the injury pattern and clinical presentation, a call was immediately placed to begin screening and preparing servicemembers to donate blood for the walking blood bank. As expected, the Role 2 supply of blood products was exhausted during the exploratory laparotomy. With servicemembers in place and screened, an additional 12 units of whole blood were collected and administered in a timely fashion. The patient was stabilized and transported to the next highest level of care. Due to the process optimization performed by the laboratory team, whole-blood transfusions were ready within an average of 22 minutes, well ahead of the 45-minute standard of care.
Operating Room First Assist
If a field surgeon is stationed at a Role 2 BAS with a forward surgical team, he/she may be required to adopt the role of operating room first assist for the trauma surgeon or orthopedic surgeon on the team, which is especially true for isolated major traumas when triage and initial stabilization measures for multiple patients are of less concern. Dermatologists receive surgical training as part of the Accreditation Council for Graduate Medical Education requirements to graduate residency, making them more than capable of surgical assisting when needed.8 In particular, dermatologists’ ability to utilize instruments appropriately and think procedurally as well as their skills in suturing are helpful.
Case Example
A 22-year-old man with several shrapnel wounds to the abdomen demonstrated free fluid in the left lower quadrant. The field surgeon (N.R.M.) assisted the trauma surgeon in opening the abdomen and running the bowel for sources of bleeding. The trauma surgeon identified the bleed and performed a ligation. The patient was then packed, closed, and prepared for transfer to a higher level of care.
Preventive Medicine
As a result of the field surgeon being on the front line of medical care in an austere environment, implementation of preventive medicine practices and disease pattern recognition are his/her responsibility. Responsibilities may include stray animal euthanasia due to prevalence of rabies, enforcement of malaria prophylaxis, medical training and maintenance of snake antivenin, and assistance with other local endemic disease. The unique skill set of dermatologists in organism identification can further bolster the speed with which vector-borne diseases are recognized and prevention and treatment measures are implemented.
Case Example
As coalition forces executed a mission in Afghanistan, US servicemembers began experiencing abdominal distress, chills, fevers (temperature >40°C), debilitating headaches, myalgia, arthralgia, and tachycardia. Initially, these patients were evacuated to the Role 2 BAS, hindering the mission. Upon inspection, patients had numerous bug bites; one astute soldier collected the arthropod guilty of the assault and brought it to the aid station. Upon inspection, the offender was identified as the Phlebotomus genus of sandflies, organisms that are well known to dermatologists as a cause of leishmaniasis. Clinical correlation resulted in the presumed diagnosis of Pappataci fever, and vector-borne disease prevention measures were then able to be further emphasized and implemented in at-risk areas, allowing the mission to continue.9 Subsequent infectious disease laboratory testing confirmed the Phlebovirus transmitted by the sandfly as the underlying cause of the illness.

The diverse role of the field surgeon in the deployed setting makes any one specialist underprepared to completely take on the role from the outset; however, with appropriate and rigorous trauma training prior to deployment, dermatologists will continue to perform as invaluable assets to the US military in conflicts now and in the future.

Practice Points
- Army dermatologists routinely deploy to combat zones as field surgeons. In this role, they provide routine, emergency, and trauma care for active-duty soldiers and coalition forces.
- With 5 years of general medical training, army dermatologists often are the most prepared to provide advanced care when compared to co-located physician assistants and combat medics.
- Maintaining basic medical skills would serve any dermatologist in case of local or national emergencies.
Neoadjuvant degarelix more effective than triptorelin for ovarian suppression
Degarelix, the gonadotropin-releasing hormone (GnRH) antagonist approved for prostate cancer, was more effective than a GnRH agonist in achieving ovarian function suppression in women with breast cancer, results of a randomized trial show.
Ovarian function suppression was achieved more rapidly and maintained more effectively with degarelix, compared with triptorelin, in the premenopausal women who were receiving letrozole for neoadjuvant endocrine therapy, investigators said.
Adverse events including hot flashes and injection site reactions were reported more often with degarelix versus the GnRH agonist in this randomized, phase 2 trial of 51 subjects.
Additional research is needed to determine whether degarelix results in superior disease control versus the current standard of care, reported Silvia Dellapasqua, MD, of the European Institute of Oncology IRCCS in Milan, Italy, and coinvestigators.
“The study is hypothesis-generating, and supports later studies to assess whether maintenance of ovarian function suppression with degarelix translates into a better clinical outcome and is worth a trade-off of increased rate of some adverse events,” the researchers wrote. The report is in the Journal of Clinical Oncology.
Patients were randomly assigned to receive degarelix plus letrozole or triptorelin plus letrozole for six 28-day cycles. Degarelix was administered subcutaneously on day 1 of each cycle, while triptorelin was administered intramuscularly on day 1 of each cycle, and oral letrozole was to be taken daily. Surgery was performed a few weeks after the last injection.
All patients achieved optimal ovarian function suppression by the end of the first cycle. However, that endpoint was achieved significantly faster among patients in the degarelix arm, at a median of 3 days, versus a median of 14 days for the GnRH agonist, the investigators reported.
The optimal ovarian function suppression was seen three times faster with degarelix (hazard ratio, 3.05; 95% confidence interval, 1.65-5.65; P less than 001), they added.
One hundred percent of patients receiving degarelix and letrozole maintained optimal ovarian function suppression throughout the study, while about 15% of patients assigned to triptorelin had suboptimal suppression after that first cycle.
The group of patients receiving degarelix had a higher rate of node-negative disease at surgery, and a higher rate of breast-conserving surgery compared with the triptorelin group, the investigators said.
There were two grade 3 adverse events, hypertension and anemia, which both occurred in the triptorelin group, and no grade 4 adverse events. The most common adverse events reported were hot flashes, occurring in 80.0% and 69.2% of the degarelix and triptorelin groups, respectively; arthralgias in 32.0% and 53.8%; insomnia in 24.0% and 11.5%; injection site reactions in 24.0% and 0%; and nausea in 16.0% and 3.8%.
The study was supported by Ferring, and by the International Breast Cancer Study Group via Frontier Science and Technology Research Foundation, Swiss Group for Clinical Cancer Research, Cancer Research Switzerland, Oncosuisse, Swiss Cancer League, and the Foundation for Clinical Cancer Research of Eastern Switzerland. The authors reported disclosures related to Ferring, Novartis, Ipsen, DVAX, Roche, Genentech, Pfizer, Celgene, and Merck, among others.

Postprandial glucose responses to identical meals vary from person to person
LOS ANGELES – .
“The reason we got interested in nutrition in general is for its important role in health and disease, but also because, reading the literature on nutrition in general, it seemed that the science was relatively poor,” Eran Segal, PhD, said at the World Congress on Insulin Resistance, Diabetes & Cardiovascular Disease. “As a testament, you can see how frequently dietary recommendations for the public are changed. For example, 30 years ago, the cover of Time magazine said that eating cholesterol in the diet is very bad for you. Fifteen years later, Time magazine said that some cholesterol is actually good for you. There are other questions, like should you be eating dairy products? I think it shows that we have a poor understanding of what healthy nutrition is for human individuals. That’s why we wanted to start a study which would collect the right amount and the right kind of data to try to answer the question of what is a healthy diet for human individuals.”
In what is believed to be the first study of its kind, Dr. Segal, professor of computer science and applied mathematics at the Weizmann Institute of Science in Rehovot, Israel, and his associates recruited 1,000 individuals and asked them to wear a continuous glucose monitor (CGM) for 1 week (Cell 2015;163[5]:1079-94). For the study, known as The Personalized Nutrition Project, participants were asked to log everything they ate into a mobile app the researchers developed. “They would select a meal from a database of 10,000 foods,” Dr. Segal explained. “Each meal has full nutritional value so at the end of the study, we had about 50,000 meals that we had measurements of postprandial glucose response to, coupled with full nutritional values.” They also collected a comprehensive profile of individuals, which included body measurements, blood tests, medical background, food frequency questionnaires, and a measurement of the microbiome by both 16S rRNA sequencing and shotgun metagenomics.
For the first part of the study, researchers supplied a breakfast to all participants: either bread, bread with butter, glucose, or fructose, in each case 50 g of available carbohydrates. “The participants were asked to consume these the morning after the night fast,” Dr. Segal said. “This allowed us to compare how the same individual responds to eating the exact same food versus how different individuals respond to eating the same food.” The researchers found that, when the same person ate the same meal on 2 different days, the glucose response was highly reproducible. In contrast, different people had widely different postmeal glucose responses to identical meals. “Some individuals responded most highly to glucose; others responded most highly to bread,” Dr. Segal said. “There was about 10% of individuals who responded to bread and butter, compared to the other test foods. These results mean that any universal diet is going to have limited efficacy in its ability to balance blood glucose levels, because some foods will spike glucose levels in one person but not in another person. It also means that the concepts we’ve been using like the glycemic index are also going to have limited efficacy.”
Next, the researchers aimed to determine what factors influence the variability in people’s responses to the same food. “We found many different correlations between the various blood markers and physical measurements that we obtained, but what was most novel was the variability in postmeal glucose response across people associated with microbiota composition and function,” Dr. Segal said. From this, he and his colleagues developed a machine-learning algorithm that integrates blood parameters, dietary habits, anthropometrics, physical activity, and gut microbiota. Using this algorithm, the prediction accuracy of personalized glucose responses achieved an r value of 0.68, which explains about 50% of the variability. For the final component of the study, the researchers randomized 26 participants to one of five dietary arms and followed for 1 week by continuous glucose monitoring. They were able to demonstrate that personally tailored diets lower the postprandial glucose response.
As a follow-up to this work, Dr. Segal and his associates enrolled 200 people with an hemoglobin A1c between 5.7% and 6.5% into the Personalized Nutrition Project for Prediabetes (PNP3) study, which investigates whether personalized diet intervention will improve postprandial blood glucose levels and other metabolic health factors in individuals with prediabetes, compared with the standard Mediterranean-style low-fat diet (NCT03222791). Participants were randomized to 6 months of standard of care following Dietary Guidelines for Americans 2015-2020, Eighth Edition, or to an algorithm diet. Primary outcomes are reduction in average glucose levels and evaluation of the total daily time of plasma glucose levels were below 140 mg/dL. Participants wore the continuous glucose monitor for the entire 6 months of intervention. “I don’t think this was ever done before,” he said. “We’re also looking at secondary metabolic endpoints and exploratory endpoints such as changes in the microbiome. We’re asking people to log everything they eat for the entire 6 months of intervention. It gives us a lot of power in terms assessing compliance. It’s an immense amount of data.”
Evaluation of the data are not yet complete, but interim results are promising. For example, he discussed results from one study participant on the algorithm diet. “Across 1 month, this person was able to entirely reduce the peaks in glucose levels and dramatic reductions in the time above 140 mg/dL in the 6-month treatment period,” said Dr. Segal, who is one of the study’s principal investigators. He disclosed that he is a paid consultant to DayTwo.

“The reason we got interested in nutrition in general is for its important role in health and disease, but also because, reading the literature on nutrition in general, it seemed that the science was relatively poor,” Eran Segal, PhD, said at the World Congress on Insulin Resistance, Diabetes & Cardiovascular Disease. “As a testament, you can see how frequently dietary recommendations for the public are changed. For example, 30 years ago, the cover of Time magazine said that eating cholesterol in the diet is very bad for you.

EXPERT ANALYSIS FROM WCIRDC 2018
Gout’s Golden Globe, resistance is fecal, eucalyptus eulogy
Eucalyptus eulogy
(“Taps” quietly plays in the background ... ) In some sad news, Quincy the diabetic koala has passed on to that great eucalyptus tree in the sky. The furry type 1 diabetic lived in San Diego, where he was recently fitted with a cutting-edge continuous glucose monitor (CGM). This allowed Quincy more time for his favorite activities (chewing and sleeping) and less time spent with pesky skin pricks.
Quincy died of pneumonia, and it is unclear whether his death was diabetes related. All we know is that he will be missed greatly. He was beloved by those with diabetes everywhere, animal or otherwise. Quincy’s successful CGM procedure also gives endocrinologists hope that the technology could eventually be used for similarly fragile humans, like babies. R.I.P., Quincy; we loved you. In lieu of flowers, donations may be made to his favorite charity, the Drop Bear Awareness Association.
What’s Latin for ‘poop’?
The study of the human microbiota has become incredibly important in recent years, but there’s no getting away from the fact that it entails experimenting on poop. Remarkably, no one’s come up with a proper technical name for this unsavory activity. However, thanks to a collaboration between a gastroenterologist and a classics professor at the University of North Carolina, that deficiency is no more. You’ve met the in vivo and in vitro study. Now, please welcome the “in vimo” study!
Why in vimo? The term fecal or “in feco” might seem obvious. But the Latin root word never referred to poop, and if there’s one thing scientists can’t have, it’s improper Latin usage. The Romans, it turns out, had lots of words for poop. The root word of laetamen referred to fertility, richness, and happiness – a tempting prospect – but was mostly used to refer to farm animal dung. Merda mostly referred to smell or stench, and stercus shared the same root word as scatology, which refers to obscene literature. Fimus, which specifically refers to manure, was thus the most precise, and it was used by literary giants such as Livy, Virgil, and Tacitus. A clear winner, and the in vimo study flushed the rest of the competition away.
And just in case you think these researchers are no fun, the name they chose for the active enzymes collected from their in vimo samples? Poopernatants. Yes, even doctors enjoy a good poop joke.
The new Breakfast Club
Researchers at the University of Illinois and the University of Texas have collaborated to study something that most of us fear greatly: high school cliques. The researchers, who may or may not have peaked in high school, took a look at high school peer crowds and influences that form those tight-knit bonds that last all of 4 years.
The study found that most of the classic cliques – the jocks, the popular crowd, the brains, the stoners, the loners – are still alive and well in today’s American school system. However, at least one new group has emerged in the last decade: the “anime/manga fans.” Researchers noted that although schools have become much more diverse, racial and ethnic stereotypes are alive and well. Thank God we only have to do high school once.
Resistance is fecal
And now, just in case you were wondering how long it would take to put our newfound knowledge of “in vimo” to use, here comes a study that has “in vimo” written all over it (metaphorically speaking, of course).
Researchers in Sweden and Finland decided to take a look at antibiotic resistance genes in sewage, because “antibiotics consumed by humans and animals are released into the environment in urine and fecal material contained in treated wastewaters and sludge applied to land.” Then they compared the abundance of the mobile antibiotic resistance genes with the abundance of a human fecal pollution marker.
That marker – a virus that infects bacteria in human feces but is rare in other animals – was “highly correlated to the abundance of antibiotic resistance genes in environmental samples,” they said in a separate written statement, which “indicates that fecal pollution can largely explain the increase in resistant bacteria often found in human-impacted environments.” The name of that marker, the virus found in feces, happens to be “crAssphage.” And yes, the A really is capitalized. Really. We are not making this up.
Gout wins a Golden Globe
Gout has a new poster girl: Great Britain’s Queen Anne. She’s been dead for more than 4 centuries, but a Hollywood version of this stout monarch is turning a famously royal affliction into the disease of the moment.
The credit goes to actress Olivia Colman, who just won a Golden Globe award for her brilliant performance in the earthy comedy “The Favourite.” Ms. Colman transforms the pain-wracked Queen Anne into a needy, manipulative, and loopy monarch who still manages to draw our sympathy.
Besides flummoxing American spell-checkers with its title, The Favourite glories in stretching the truth about the queen’s private life. But she really does seem to have had the “disease of kings,” which has long been linked to the rich, fatty diets enjoyed by blue bloods.
Now, there’s talk that high-protein, meat-friendly keto and paleo diets are boosting rates among the young. This theory got an airing last week in a New York Magazine article titled “Why Gout Is Making a Comeback.”
The truth may be more complicated. Over the last few years, researchers have cast doubt on the keto-leads-to-gout theory and suggested that fructose in sugar may be the real culprit. According to this hypothesis, gout afflicted British royals as they developed a communal sweet tooth during the early days of the sugar trade. Gout then spread to the general population as sugar became more accessible.
The gout debate will continue. As for Olivia Colman, she will soon grace smaller screens with her performance as Queen Elizabeth II in Netflix’s series “The Crown.”
QE II isn’t known for having suffered from any major diseases. But at her next checkup, we do think she should have that stiff upper lip looked at.

As deep sleep decreases, Alzheimer’s pathology – particularly tau – increases
The protein was evident in areas associated with memory consolidation, typically affected in Alzheimer’s disease: the entorhinal, parahippocampal, inferior parietal, insula, isthmus cingulate, lingual, supramarginal, and orbitofrontal regions.
Because the findings were observed in a population of cognitively normal and minimally impaired subjects, they suggest a role for sleep studies in assessing the risk for cognitive decline and Alzheimer’s disease, and in monitoring patients with the disease, reported Brendan P. Lucey, MD, and his colleagues. The report is in Science and Translational Medicine (Sci Transl Med. 2019 Jan 9;11:eaau6550).
“With the rising incidence of Alzheimer’s disease in an aging population, our findings have potential application in both clinical trials and patient screening for Alzheimer’s disease to noninvasively monitor for progression of Alzheimer’s disease pathology,” wrote Dr. Lucey, director of the Sleep Medicine Center and assistant professor of neurology at Washington University in St. Louis. “For instance, periodically measuring non-REM slow wave activity, in conjunction with other biomarkers, may have utility for monitoring Alzheimer’s disease risk or response to an Alzheimer’s disease treatment.”
Dr. Lucey and his colleagues examined sleep architecture and tau and amyloid deposition in 119 subjects enrolled in longitudinal aging studies. For 6 nights, subjects slept with a single-channel EEG monitor on. They also underwent cognitive testing and genotyping for Alzheimer’s disease risk factors.
Subjects were a mean of 74 years old. Almost 80% had normal cognition as measured by the Clinical Dementia Rating Scale (CDR); the remainder had very mild cognitive impairment (CDR 0.5)
Among those with positive biomarker findings, sleep architecture was altered in several ways: lower REM latency, lower wake after sleep onset, prolonged sleep-onset latency, and longer self-reported total sleep time. The differences were evident in those with normal cognition, but even more pronounced in those with mild cognitive impairment. Despite the longer sleep times, however, sleep efficiency was decreased.
Decreased non-REM slow wave activity was associated with increased tau deposition. The protein was largely concentrated in areas of typical Alzheimer’s disease pathology (entorhinal, parahippocampal, orbital frontal, precuneus, inferior parietal, and inferior temporal regions). There were no significant associations between non-REM slow wave activity and amyloid deposits.
Other sleep parameters, however, were associated with amyloid, including REM latency and sleep latency, “suggesting that as amyloid-beta deposition increased, the time to fall asleep and enter REM sleep decreased,” the investigators said.
Those with tau pathology also slept longer, reporting more daytime naps. “This suggests that participants with greater tau pathology experienced daytime sleepiness despite increased total sleep time.”
“These results, coupled with the non-REM slow wave activity findings, suggest that the quality of sleep decreases with increasing tau despite increased sleep time.” Questions about napping should probably be included in dementia screening discussions, they said.
The study was largely funded by the National Institutes of Health. Dr. Lucey had no financial conflicts.

The protein was evident in areas associated with memory consolidation, typically affected in Alzheimer’s disease: the entorhinal, parahippocampal, inferior parietal, insula, isthmus cingulate, lingual, supramarginal, and orbitofrontal regions.
Because the findings were observed in a population of cognitively normal and minimally impaired subjects, they suggest a role for sleep studies in assessing the risk for cognitive decline and Alzheimer’s disease, and in monitoring patients with the disease, reported Brendan P. Lucey, MD, and his colleagues. The report is in Science and Translational Medicine (Sci Transl Med. 2019 Jan 9;11:eaau6550).
“With the rising incidence of Alzheimer’s disease in an aging population, our findings have potential application in both clinical trials and patient screening for Alzheimer’s disease to noninvasively monitor for progression of Alzheimer’s disease pathology,” wrote Dr. Lucey, director of the Sleep Medicine Center and assistant professor of neurology at Washington University in St. Louis. “For instance, periodically measuring non-REM slow wave activity, in conjunction with other biomarkers, may have utility for monitoring Alzheimer’s disease risk or response to an Alzheimer’s disease treatment.”
Dr. Lucey and his colleagues examined sleep architecture and tau and amyloid deposition in 119 subjects enrolled in longitudinal aging studies. For 6 nights, subjects slept with a single-channel EEG monitor on. They also underwent cognitive testing and genotyping for Alzheimer’s disease risk factors.
Subjects were a mean of 74 years old. Almost 80% had normal cognition as measured by the Clinical Dementia Rating Scale (CDR); the remainder had very mild cognitive impairment (CDR 0.5)
Among those with positive biomarker findings, sleep architecture was altered in several ways: lower REM latency, lower wake after sleep onset, prolonged sleep-onset latency, and longer self-reported total sleep time. The differences were evident in those with normal cognition, but even more pronounced in those with mild cognitive impairment. Despite the longer sleep times, however, sleep efficiency was decreased.

Autologous Hematopoietic Stem Cells May Treat Aggressive MS Effectively
The therapy may halt disease activity and promote sustained functional improvement.
BERLIN—Autologous hematopoietic stem cell transplantation (HSCT) could prevent disease activity and promote functional recovery in patients with aggressive multiple sclerosis (MS), according to a retrospective case series presented at ECTRIMS 2018.
A review article suggested that the likelihood of achieving no evidence of disease activity (NEDA) after two years of treatment ranges between 10% and 60%
Like other highly effective therapies, HSCT has been considered to entail significant safety risks. When the European Society for Blood and Marrow Transplantation (EBMT) reviewed their data, however, they identified one death related to HSCT between 2012 and 2016. The estimated risk of death from HSCT is thus approximately 0.2%. “Mortality associated with transplantation has decreased so much that it is almost into the range of other standard disease-modifying therapies,” said Joyutpal Das, MBBS, a neuroscientist at Royal Hallamshire Hospital in Sheffield, United Kingdom.
EBMT recommended that neurologists consider HSCT for patients with highly active radiologic and clinical disease who have failed to respond to standard disease-modifying therapy. The treatment can be considered as first-line therapy for patients with exceptionally active disease who have become disabled, they added.
A Retrospective Case Series
To examine the efficacy of HSCT in this patient population, Dr. Das and colleagues conducted a retrospective case series of 20 patients with MS from five centers in various countries. The patients’ treating physicians decided that HSCT should be their first-line therapy. Dr. Das and colleagues used NEDA-3 (which includes relapses, disability progression, and MRI activity) as their primary outcome. Each patient underwent brain MRI during the first six months of treatment and at six- to 12-month intervals thereafter.
The case series included equal numbers of men and women. All patients had frequent relapses, incomplete recovery, and multiple gadolinium enhancing lesions on serial MRI scans. The lesions often affected the brainstem, cerebellum, and spine. Patients’ median age of diagnosis and median age of treatment were 28. The time between the first onset of symptoms and treatment was nine months, and that between diagnosis and treatment was five months. Patients’ median pretreatment Expanded Disability Status Scale (EDSS) score was 6.5. Median follow-up duration was 2.5 years.
EDSS Score Improved
Three patients had new lesions during the first six months of treatment, but no patients had new lesions on subsequent MRI scans. “It has been suggested … that if you want to use NEDA to measure efficacy, the patient should have rebaseline imaging after the initiation of treatment,” said Dr. Das. “If we use our six-month scan as rebaseline imaging, then we have no further disease activity on MRI scan.”
After treatment initiation, the median EDSS score decreased from 6.5 to 2. Patients’ median improvement on EDSS score was 2.5 points, which was statistically significant. Seven patients had an EDSS score improvement of 3 points or greater. EDSS score improved for all but one patient. The results suggest that HSCT induced rapid and sustained remission, said Dr. Das.
The investigators observed typical transplant-related toxicity in the population, and no patient died. One woman conceived and gave birth to a healthy baby, and one man fathered a healthy baby.

Interferon Beta May Not Affect Pregnancy Outcomes in MS
The rates of live births and congenital anomalies are similar between exposed and nonexposed patients.
BERLIN—European registry data do not support the hypothesis that exposure to interferon beta before conception or during pregnancy adversely affects pregnancy outcome or infant outcome, according to an analysis presented at ECTRIMS 2018.
In women, diagnosis of multiple sclerosis (MS) and treatment initiation often occur during childbearing years, but neurologists have not reached consensus about treatment before or during pregnancy. The European Interferon Beta Pregnancy Registry was created to gather evidence about the effect of this treatment on maternal and fetal outcomes. A separate population-based cohort study examined health care registry data from Finland and Sweden (ie, Nordic registries) for the same purpose.
An Analysis of Prospective Data
Kerstin Hellwig, MD, Senior Consultant Neurologist and researcher at St. Joseph and St. Elizabeth Hospital and Ruhr University in Bochum, Germany, and colleagues examined these databases to evaluate the prevalence of pregnancy and infant outcomes in women with MS who had been exposed to interferon beta. The investigators analyzed 948 pregnancy reports with recorded pregnancy outcomes from the European Interferon Beta Pregnancy Registry. They also examined 875 pregnancy events in the Nordic registries among patients exposed to interferon beta and other treatments and 1,831 events among untreated patients.
Treatment Did Not Affect Birth Weight
Approximately 82% of pregnancies in the European registry had an outcome of live birth without congenital anomalies. The prevalence of spontaneous abortions and live births with congenital anomalies were similar to those reported in the general population.
About 98% of pregnancies in the exposed cohort of the Nordic registries had an outcome of live birth without congenital anomalies. This result is similar to the corresponding 97% rate in the nonexposed cohort. The prevalence of spontaneous abortions and congenital anomalies also were similar between the exposed and nonexposed cohorts of the Nordic registries.
Birth weights ranged from 580 g to 5,160 g in the Nordic registries. The proportion of babies with low or very low birth weight was 5.0% in the interferon-exposed cohort, 4.7% among babies exposed to interferon and other treatments, and 5.8% among nonexposed babies. Mean birth weight was 3,421.2 g in the interferon-exposed cohort, 3,434.3 g in the cohort exposed to interferon and other treatments, and 3,389.3 g in the nonexposed cohort. These weights were consistent with results from the prospective German pregnancy registry, according to the authors. Birth weights were not recorded systematically in the European registry.
“The European Interferon Beta Pregnancy Registry showed no evidence that interferon beta exposure before conception or during pregnancy adversely affected pregnancy or infant outcomes,” said Dr. Hellwig and colleagues. “This is consistent with data collected from the Nordic registers.”

Alcohol use, psychological distress associated with possible RBD
(RBD), according to a population-based cohort study published in Neurology. In addition, the results also replicate previous findings of an association between possible RBD and smoking, low education, and male sex.
The risk factors for RBD have been studied comparatively little. “While much is still unknown about RBD, it can be caused by medications or it may be an early sign of another neurologic condition like Parkinson’s disease, dementia with Lewy bodies, or multiple system atrophy,” according to Ronald B. Postuma, MD, an associate professor at McGill University, Montreal. “Identifying lifestyle and personal risk factors linked to this sleep disorder may lead to finding ways to reduce the chances of developing it.”
To assess sociodemographic, socioeconomic, and clinical correlates of possible RBD, Dr. Postuma and his colleagues examined baseline data collected between 2012 and 2015 in the Canadian Longitudinal Study on Aging (CLSA), which included 30,097 participants. To screen for possible RBD, the CLSA researchers asked patients, “Have you ever been told, or suspected yourself, that you seem to ‘act out your dreams’ while asleep [e.g., punching, flailing your arms in the air, making running movements, etc.]?” Participants answered additional questions to rule out RBD mimics. Patients with symptom onset before age 20 years, positive apnea screen, or a diagnosis of dementia, Alzheimer’s disease, parkinsonism, or Parkinson’s disease were excluded from analysis.
In all, 3,271 participants screened positive for possible RBD. After the investigators excluded participants with potential mimics, 958 patients (about 3.2% of the total population) remained in the analysis. Approximately 59% of patients with possible RBD were male, compared with 42% of controls. Patients with possible RBD were more likely to be married, in a common-law relationship, or widowed.
Participants with possible RBD had slightly less education (estimated mean, 13.2 years vs. 13.6 years) and lower income, compared with controls. Participants with possible RBD retired at a slightly younger age (57.5 years vs. 58.6 years) and were more likely to have retired because of health concerns (28.9% vs. 22.0%), compared with controls.
In addition, patients with possible RBD were more likely to drink more and to be moderate to heavy drinkers than controls; they were also more likely to be current or past smokers. Antidepressant use was more frequent and psychological distress was greater among participants with possible RBD.
When the investigators performed a multivariable logistic regression analysis, the associations between possible RBD and male sex and relationship status remained. Lower educational level, but not income level, also remained associated with possible RBD. Furthermore, retirement age and having reported retirement because of health concerns remained significantly associated with possible RBD, as did the amount of alcohol consumed weekly and moderate to heavy drinking. Sensitivity analyses did not change the results significantly.
One of the study’s limitations is its reliance on self-report to identify participants with possible RBD, the authors wrote. The prevalence of possible RBD in the study was 3.2%, but research using polysomnography has found a prevalence of about 1%. Thus, the majority of cases in this study may have other disorders such as restless legs syndrome or periodic limb movements. Furthermore, many participants who enact their dreams (such as unmarried people) are likely unaware of it. Finally, the researchers did not measure several variables of interest, such as consumption of caffeinated products.
“The main advantages of our current study are the large sample size; the systematic population-based sampling; the capacity to adjust for diverse potential confounding variables, including mental illness; and the ability to screen out RBD mimics,” the authors concluded.

Furthermore, retirement age and having reported retirement because of health concerns remained significantly associated with possible RBD, as did the amount of alcohol consumed weekly and moderate to heavy drinking. Sensitivity analyses did not change the results significantly.
One of the study’s limitations is its reliance on self-report to identify participants with possible RBD, the authors wrote. The prevalence of possible RBD in the study was 3.2%, but research using polysomnography has found a prevalence of about 1%. Thus, the majority of cases in this study may have other disorders such as restless legs syndrome or periodic limb movements. Furthermore, many participants who enact their dreams (such as unmarried people) are likely unaware of it. Finally, the researchers did not measure several variables of interest, such as consumption of caffeinated products.
“The main advantages of our current study are the large sample size; the systematic population-based sampling; the capacity to adjust for diverse potential confounding variables, including mental illness; and the ability to screen out RBD mimics,” the authors concluded.

(RBD), according to a population-based cohort study published in Neurology. In addition, the results also replicate previous findings of an association between possible RBD and smoking, low education, and male sex.
The risk factors for RBD have been studied comparatively little. “While much is still unknown about RBD, it can be caused by medications or it may be an early sign of another neurologic condition like Parkinson’s disease, dementia with Lewy bodies, or multiple system atrophy,” according to Ronald B. Postuma, MD, an associate professor at McGill University, Montreal. “Identifying lifestyle and personal risk factors linked to this sleep disorder may lead to finding ways to reduce the chances of developing it.”
To assess sociodemographic, socioeconomic, and clinical correlates of possible RBD, Dr. Postuma and his colleagues examined baseline data collected between 2012 and 2015 in the Canadian Longitudinal Study on Aging (CLSA), which included 30,097 participants. To screen for possible RBD, the CLSA researchers asked patients, “Have you ever been told, or suspected yourself, that you seem to ‘act out your dreams’ while asleep [e.g., punching, flailing your arms in the air, making running movements, etc.]?” Participants answered additional questions to rule out RBD mimics. Patients with symptom onset before age 20 years, positive apnea screen, or a diagnosis of dementia, Alzheimer’s disease, parkinsonism, or Parkinson’s disease were excluded from analysis.
In all, 3,271 participants screened positive for possible RBD. After the investigators excluded participants with potential mimics, 958 patients (about 3.2% of the total population) remained in the analysis. Approximately 59% of patients with possible RBD were male, compared with 42% of controls. Patients with possible RBD were more likely to be married, in a common-law relationship, or widowed.
Participants with possible RBD had slightly less education (estimated mean, 13.2 years vs. 13.6 years) and lower income, compared with controls. Participants with possible RBD retired at a slightly younger age (57.5 years vs. 58.6 years) and were more likely to have retired because of health concerns (28.9% vs. 22.0%), compared with controls.
In addition, patients with possible RBD were more likely to drink more and to be moderate to heavy drinkers than controls; they were also more likely to be current or past smokers. Antidepressant use was more frequent and psychological distress was greater among participants with possible RBD.

ACOG updates guidance on chronic hypertension in pregnancy, gestational hypertension
Ob.gyns. will need to focus more on individualized care as they use the two new practice bulletins, one on chronic hypertension in pregnancy and one on gestational hypertension and preeclampsia, released by the American College of Obstetricians and Gynecologists’ Committee on Practice Bulletins–Obstetrics.
The bulletins will replace the 2013 ACOG hypertension in pregnancy task force report and are published in the January issue of Obstetrics & Gynecology.
“The task force was a tour de force in creating a comprehensive view of hypertensive diseases of pregnancy, including research,” Christian M. Pettker, MD, who helped develop both practice bulletins, stated in a press release. “The updated guidance provides clearer recommendations for the management of gestational hypertension with severe-range blood pressure, an emphasis on and instructions for timely treatment of acutely elevated blood pressures, and more defined recommendations for the management of pain in postoperative patients with hypertension.”
“Ob.gyns. will need to focus more on individualized care and may find it’s best to err on the side of caution because the appropriate treatment of hypertensive diseases in pregnancy may be the most important focus of our attempts to improve maternal mortality and morbidity in the United States,” he said.*
Gestational hypertension or preeclampsia
For women with gestational hypertension or preeclampsia at 37 weeks of gestation or later without severe features, the guidelines recommend delivery rather than expectant management.
Those patients with severe features of gestational hypertension or preeclampsia or eclampsia should receive magnesium sulfate to prevent or treat seizures.
Patients should receive low-dose aspirin (81 mg/day) for preeclampsia prophylaxis between 12 weeks and 28 weeks of gestation if they have high-risk factors of preeclampsia such as multifetal gestation, a previous pregnancy with preeclampsia, renal disease, autoimmune disease, type 1 or type 2 diabetes mellitus, chronic hypertension, or a previous pregnancy with preeclampsia; or more than one moderate risk factor such as a family history of preeclampsia, maternal age greater than 35 years, first pregnancy, body mass index greater than 30, personal history factors, or sociodemographic characteristics.
NSAIDs should continue to be used in preference to opioid analgesics.
The guidance also discusses mode of delivery, antihypertensive drugs and thresholds for treatment, management of acute complications for preeclampsia with HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome, the optimal treatment for eclampsia, and postpartum hypertension and headache.
Chronic hypertension
Pregnant women with chronic hypertension also should receive low-dose aspirin between 12 weeks and 28 weeks of gestation. Antihypertensive therapy should be initiated for women with persistent chronic hypertension at systolic pressure of 160 mm Hg or higher and/or diastolic pressure of 110 mm Hg or higher. Consider treating patients at lower blood pressure (BP) thresholds depending on comorbidities or underlying impaired renal function.
ACOG has recommended treating pregnant patients as chronically hypertensive according to recently changed criteria from the American College of Cardiology and the American Heart Association, which call for classifying blood pressure into the following categories:
- Normal. Systolic BP less than 120 mm Hg; diastolic BP less than 80 mm Hg.
- Elevated. Systolic BP greater than or equal to 120-129 mm Hg; diastolic BP greater than 80 mm Hg.
- Stage 1 hypertension. Systolic BP, 130-139 mm Hg; diastolic BP, 80-89 mm Hg.
- Stage 2 hypertension. Systolic BP greater than or equal to 140 mm Hg; diastolic BP greater than or equal to 90 mm Hg.
“The new blood pressure ranges for nonpregnant women have a lower threshold for hypertension diagnosis compared to ACOG’s criteria,” Dr. Pettker said. “This will likely cause a general increase in patients classified as chronic hypertensive and will require shared decision making by the ob.gyn. and the patient regarding appropriate management in pregnancy.”
The guideline also discusses chronic hypertension with superimposed preeclampsia; tests for baseline evaluation of chronic hypertension in pregnancy; common oral antihypertensive agents to use in pregnancy and those to use for urgent blood pressure control in pregnancy; control of acute-onset severe-range hypertension; and postpartum considerations in patients with chronic hypertension.
