Ectopic prolactin-secreting microadenomas are rare and management is often surgical in contrast to intrasellar pituitary prolactin-secreting microadenomas. We present a case of ectopic dopamine-resistant microprolactinoma treated with cabergoline which led to symptom resolution, hormonal remission, and cystic degeneration of the tumor. A 30-year-old active duty male presented with a chief complaint of inability to maintain an erection for 6 months. ⋯ Management for any prolactinoma has three primary goals: remittance of symptoms, decrease in prolactin levels, and decrease in tumor size. These are achieved through primarily medical management or surgery. Even though ectopic microprolactinomas are still frequently addressed surgically, this case shows that medical therapy can successfully treat ectopic prolactin-secreting pituitary microadenomas even in cases of dopamine resistance.

Case Reports
Pulmonary Barotrauma in a BUD/S Candidate Following Shallow Dives Using the MK 25 Rebreather.
Pulmonary barotrauma of ascent is a well-recognized risk of compressed air diving in the civilian and military diving communities. Chest imaging is a beneficial adjunct to clinical evaluation in screening select individuals for fitness to dive, evaluating dive-related injuries, and safely returning individuals to diving duty. We present a case of a 26-year-old male U. ⋯ The risk of pulmonary barotrauma may be decreased through adequate training and thorough medical screening to include assessing for symptoms of infection before every dive. In cases of acute pulmonary barotrauma, chest radiographs may be used to screen for thoracic injury. Chest CT with inspiratory and expiratory sequences should be used to screen dive candidates on a case-by-case basis and to evaluate lung injury and predisposing pulmonary conditions following pulmonary barotrauma.

Airway obstruction is the third most common cause of preventable death on the battlefield, accounting for 1%-2% of total combat fatalities. No previous surgical cricothyroidotomy (SC) studies have analyzed the learning curve required to obtain proficiency despite being studied in numerous other surgical technique training experiments. The aims of this study were to establish expert SC performance criteria, develop a novel standardized SC curriculum, and determine the necessary number of practice iterations required by a novice to reach this pre-determined performance goal. ⋯ This study successfully defined SC checklist scores and completion times based on the performance of experienced surgeons on a simulator. Using these criteria and the principles of mastery learning, novices with little knowledge and experience in SC were successfully trained to the level of experienced providers. All subjects met performance targets after training and overall performance plateaued after approximately seven iterations. Over two-thirds of subjects achieved the performance target on the first testing attempt in a simulated helicopter environment. Performance was comparable between medical student and corpsmen subgroups. Further research will assess the durability of maintaining SC skills and the timing for introducing refresher courses after initial skill acquisition.

Chronic pain (CP) commonly presents alongside psychiatric conditions such as depression, PTSD, and generalized anxiety. The current study sought to better understand this complex relationship by determining whether anxiety and depression symptom severity mediated the relationship between DSM-5 PTSD symptom clusters and pain symptoms in a sample of 663 Canadian Armed Forces (CAF) personnel and veterans seeking treatment for mental health conditions. ⋯ Findings emphasize the importance of including anxiety and depression in models of PTSD and pain, particularly in samples where psychiatric comorbidity is high. Clinically, results highlight the need for improved treatment regimens that address pain symptoms alongside common psychiatric comorbidities.

This brief report describes the process, used by the 1st Infantry Division (1ID) and Irwin Army Community Hospital (IACH) at Fort Riley, Kansas, for conducting pooled testing collection of over 2,500 Soldiers prior to a large-scale exercise involving multiple units. ⋯ Pooled testing collection is a complex process that may continue to be a requirement for mass screening of COVID-19 prior to military operations. While planning should be tailored to the specific mission and unit, key factors that the authors feel are required for pooled testing to be successful in any situation are standardized training and personnel continuity, quality assurance, administrative oversight by the unit, and collaboration and communication between all involved entities.
