This paper reports the first case of chronic exertional compartment syndrome in the arm treated surgically. The diagnosis was made in a patient who is under 30 years old, military, and very athletic, with recurrent exertional pain in the anterior compartment of the arms associated with rhabdomyolysis. The high-pressure measurements in the arms' anterior compartment after exertional exercise confirmed the diagnosis. Given the patient's functional demands, a surgical treatment of fasciotomy of the anterior compartment by miniapproach was performed and allowed the resolution of symptomatology with a return to sport at the same level after 3 months.

The goal of this exploratory study was to examine the relationships between sleep consistency and workplace resilience among soldiers stationed in a challenging Arctic environment. ⋯ The study highlights the relationship between seasonality, sleep consistency, and psychological well-being. The results indicate the potential importance of sleep consistency in psychological functioning, suggesting that future work should manipulate factors known to increase sleep consistency to assess whether improved sleep consistency can enhance the well-being of soldiers. Such efforts would be of particular value in an Arctic environment, where seasonality effects are large and sleep consistency is difficult to maintain.

This was an in vivo animal study designed to investigate the interaction between dexamethasone (Dex) and microRNA-204 (miR-204) in a mouse alkali burn-induced corneal neovascularization (CNV) model. The function of miR-204 was then investigated in human mammary epithelial cells (HMECs) in vitro. ⋯ The role of Dex in attenuating CNV may be partly attributed to miR-204. MiR-204 may be a potential therapeutic target in alkali burn-induced CNV.

Finger amputations can lead to loss of work time and suboptimal function, particularly in the active duty military. There is a paucity of epidemiologic and outcome data for these injuries. The purposes of this study are to define key demographic data pertaining to transphalangeal finger amputations in the U.S. Military and to assess epidemiological data to define risk factors for medical readiness following finger injuries. ⋯ Within a physically high-demand population, traumatic finger amputation can limit duties and may lead to medical separation from service. Traumatic finger amputations are common and often require 6 weeks of restricted short-term disability, particularly in a tobacco-using, young, physically active cohort.

Military service members (SMs) demonstrate high rates of patellofemoral chondral defects (PFCDs) that are difficult to diagnosis and, if untreated, result in a cascade of events eventually leading to osteoarthritis. Running is an essential occupational task for SMs; however, there is little evidence regarding techniques to maintain running ability in individuals with cartilage defects. The purpose of this case series was to assess the clinical application of foot strike run retraining in patients with PFCDs. ⋯ Biomechanical analysis showed that both patients demonstrated a 63% to 70% reduction in average and peak vertical ground reaction force loading rates post-treatment. Modification of foot strike pattern from rear to non-rearfoot strike during running for individuals with PFCD can reduce the magnitude of impact loading, which potentially limits disease progression. These findings suggest that foot strike run retraining may be a feasible strategy to reduce pain and improve function in SMs with PFCD who are required to run for occupational responsibilities.
