Testicular pain has a wide differential and the nonspecific presentation should be triaged rapidly for urgent diagnosis and treatment. Scrotal pyoceles are uncommon collections of purulent fluid between the visceral and parietal tunica vaginalis, usually secondary to acute epididymo-orchitis, intra-abdominal infection, or trauma. Epididymitis and epididymo-orchitis are generally secondary to sexually transmitted infections or urinary tract pathogens. ⋯ Ultrasonography is the preferred method of diagnostic imaging, which can show a classic "falling snow" sign, loculations, or gas. The treatment for a scrotal pyocele is pain control, fluid resuscitation, broad-spectrum antibiotics, and early urology/general surgery consultation. In such cases, Fournier gangrene (FG) should be clinically ruled out and the presence of signs of Fournier gangrene should be met with an urgent surgical consult.

Occult HBV infection (OBI) is defined as the presence of detectable hepatitis B virus (HBV) DNA in HBV surface antigen (HBsAg) negative individuals. Rarely, OBI is attributed to mutant HBV that cannot be detected by commercial assays, but most cases occur in the setting of chronic hepatitis B, particularly infection with wild-type viruses associated with strong HBV suppression. OBI is a high-risk diagnosis as it is associated with multiple complications: HBV reactivation in immunocompromised states, transmission of HBV, progression of liver disease, and hepatocellular carcinoma. ⋯ This case series illustrates the clinical significance of OBI and the importance of screening for OBI in HBsAg negative patients with signs of chronic or severe hepatic inflammation. It also prompts an intriguing question regarding the prevalence of both HBV and OBI in the United States military and whether or not routine screening for HBV should be implemented in this population. Further study is warranted to determine if adding HBV core antibody to a universally employed screening regimen would be beneficial.

Traumatic brain injury (TBI) has been the leading cause of morbidity and mortality in recent military conflicts and deployment-related TBIs are most commonly caused by blast. However, knowledge of risk factors that increase susceptibility to TBI following an acute, high-level blast is limited. We hypothesized that recurrent occupational overpressure exposure (ROPE) may be one factor that increases susceptibility to mild TBI (mTBI) following blast. ⋯ Blast exposure and ROPE were independently associated with mTBIs, and Marines with both blast exposure during deployment and ROPE were especially likely to sustain an mTBI. This suggests that ROPE heightens the risk of mTBI following blast. Ongoing research is examining the severity, symptomology, and sequelae of TBIs as a function of ROPE.

This study examined working memory impairment following mild traumatic brain injury (mTBI) among active duty service members charged with criminal offenses. The prevalence of mTBI among service members involved in the military justice system is unknown. Impairments associated with mTBI may affect cognitive processes related to psycholegal capacities, and history of mTBI may have a persuasive appeal when explaining questions of culpability. The degree to which mTBI affects psycholegal abilities through cognitive impairment, however, is unknown. ⋯ This study suggests that a history of mTBI is common among service members charged with criminal offenses. The findings that working memory scores were in the average range among service members with mTBI history may suggest that history of mTBI does not impair psycholegal relevant cognition. More research is needed to clarify how history of mTBI affects service member psycholegal capacities.

In patients with prior myocardial infarction (MI), cardiac rehabilitation (CR) has been shown to reduce all-cause mortality, cardiac mortality, and risk of recurrent MI. Medically supervised cardiac rehab has challenges such as increased patient and center cost, patient transportation issues, patient time commitment, and increased need for resources. Home-based cardiac rehabilitation (HBCR) is an innovative alternative to medically supervised CR which can help to address some of the aforementioned issues. HBCR has been shown to have similar patient outcomes when compared to medically supervised CR; however, implantation efforts and experiences within Veteran Affair (VA) facilities were limited. Thus, we sought to describe our implementation efforts and outcomes of HBCR at our VA medical center, since our VA medical center does not offer an on-site medically supervised CR program. ⋯ HBCR is an effective alternative to facility-based CR. Veterans who completed the program showed improvement in physical capacity and functional status. Compared to those who were eligible but did not complete the program, hospitalization for heart failure was reduced after completing HBCR.
