Guillain-Barre syndrome (GBS) is an acute monophasic immune-mediated polyradiculoneuropathy characterized by rapidly evolving ascending weakness, mild sensory loss, and hypo- or areflexia, typically progressing to peak symptoms over the course of 4 weeks. The precise mechanism is unclear but is proposed to be an immune-mediated reaction with the generation of antibodies against peripheral nerves triggered by a preceding viral infection. Acute motor and sensory axonal neuropathy (AMSAN) is a rare and severe variant of Guillain-Barre syndrome with limited published literature. ⋯ She presented with worsening diplopia, bilateral distal upper and lower extremity paresthesias as well as progressively worsening bilateral upper extremity weakness. Her clinical picture was complicated by constitutional symptoms, diffuse lymphadenopathy, no preceding viral illness, and marked clinical deterioration. Ultimately, she was diagnosed with acute motor and sensory axonal neuropathy in the setting of a new diagnosis of systemic lupus erythematosus, a rarely described association emphasizing the importance of a thorough evaluation for underlying causes of acute neurologic pathologies.

Combat-related traumatic injury (CRTI) adversely affects heart rate variability (HRV). The mediating effect of mental and physical health factors on the relationship between CRTI, its severity and HRV has not been previously studied and investigated. ⋯ The findings suggest that greater physical function may improve HRV following CRTI. Longitudinal studies are warranted to further validate these findings.

U.S. Navy Medicine's temporary limited duty (LIMDU) program is the primary vehicle for managing the medical care and subsequent career outcomes of the ill and injured active component (AC) Sailors and Marines to ensure a medically ready force. Before the LIMDU Sailor and Marine Readiness Tracker System (SMART) came online, it was very difficult to examine LIMDU program administration metrics, patients' experiences during LIMDU, and their subsequent health and career outcomes. This study examined the LIMDU patient population's demographic, military career, and LIMDU-specific characteristics; identified characteristics that differed significantly by military service; and evaluated potentially modifiable factors associated with patient outcomes. ⋯ Navy Medicine's SMART data is an important new resource for LIMDU program evaluation and population-level patient research, despite the data limitations and concerns identified and addressed by this study. The study results provide a baseline empirical understanding about the LIMDU patient population. Further research is necessary to interrogate the validity of these results over a longer period and to initiate other lines of inquiry. While the construction of the larger project's LIMDU patient population longitudinal dataset required a significant initial investment, future dividends from ongoing work are anticipated. Results derived from verified SMART data will benefit Navy Medicine, operational commands, and LIMDU patients alike by informing continuing efforts to improve patient health and career outcomes, identify and implement best clinical and administrative practices, and optimize force readiness.

Spontaneous coronary artery dissection (SCAD) is a non-atherosclerotic cause of myocardial infarction and sudden cardiac death in young individuals without significant cardiovascular risk factors. The etiology of SCAD appears to be multifactorial and is often precipitated by physical and emotional stress superimposed on underlying arteriopathy, connective tissue disorders, systemic inflammatory disorders, genetic factors, and hormonal influences. There are no current societal guidelines to stratify young soldiers' risk of developing SCAD. ⋯ We present a 21-year-old active duty male who was transferred from Okinawa, Japan to a tertiary military medical center for evaluation of hypercoagulable conditions after CT revealed non-obstructing portal venous thrombosis extending to right hepatic vein, splenic vein thrombosis with splenic infarct, and bilateral wedge-shaped renal infarct. Extensive work-up ultimately revealed mid-left anterior descending spiral dissection with transmural infarct of inferior, anteroseptal, and inferoseptal wall resulting in the formation of left ventricular thrombus, subsequently causing thromboembolism to multiple organs. This case demonstrates the ramifications of SCAD when diagnosis and management are delayed and serve as a poignant reminder for all providers to include SCAD in the differential diagnosis for young soldiers with atypical chest pain.

To determine if universal access to care for military beneficiaries improves timing of presentation to prenatal care (PNC) in adolescent and young adult (AYA) pregnancies, improving maternal and neonatal outcomes. ⋯ Our findings suggest that expanded universal access to health care may improve AYA pregnancy and delivery outcomes. Infants born to AYA military beneficiaries have improved neonatal outcomes compared to nationally published data. These results may correlate to improved maternal access within a free or low-cost healthcare system.
