Rectus sheath hematoma (RSH) develops due to rupture of epigastric arteries or the rectus muscle. Although RSH incidence rate is low, it poses a significant diagnostic dilemma. We evaluated the risk factors for RSH, its presentation, management, and outcomes for 115 patients hospitalized with confirmed RSH by computed tomography scan between January 2005 and June 2009. More than three-fourth (77.4%) of the patients were on anticoagulation therapy, 58.3% patients had chronic kidney disease (CKD) stage ≥3, 51.3% had abdominal injections, 41.7% were on steroids/immunosuppressant therapy, 37.4% had abdominal surgery/trauma, 33.9% had cough, femoral puncture was performed in 31.3% of patients, and 29.5% were on antiplatelet therapy. Rectus sheath hematoma was not an attributable cause in any of the 17 deaths. Mortality was significantly higher in patients with CKD stage ≥3 (P = .03) or who required transfusion (P = .007). Better understanding of RSH risk factors will facilitate early diagnoses and improve management.

Background: The incidence of invasive melanoma is rising, and approval for the first immune checkpoint inhibitor (ICI) to treat metastatic melanoma occurred in 2011. We aim to describe the epidemiology and outcomes in recent years, sociodemographic factors associated with the presence of metastasis at diagnosis, and the real-world impact of ICI approval on survival based on melanoma subtype and race. Methods: This is a retrospective analysis of the National Cancer Database (NCDB) from the years 2004–2015. The primary outcome was the overall survival of metastatic melanoma by subtype. Secondary outcomes included sociodemographic factors associated with the presence of metastasis at diagnosis and the impact of treatment facility type and ICI approval on the survival of metastatic melanoma. Results: Of the 419,773 invasive melanoma cases, 93.80% were cutaneous, and 4.92% were metastatic at presentation. The odds of presenting with metastatic disease were higher in African Americans (AA) compared to Caucasians (OR 2.37; 95% CI 2.11–2.66, p < 0.001). Treatment of metastatic melanoma at an academic/research facility was associated with lower mortality versus community cancer programs (OR 0.75, 95 % CI 0.69–0.81, p-value < 0.001). Improvement in survival of metastatic melanoma was noted for Caucasians after the introduction of ICI (adjusted HR 0.80, 95% CI 0.78–0.83, p < 0.001); however, this was not statistically significant for AA (adjusted HR 0.80, 95% CI 0.62–1.02, p-value = 0.073) or ocular cases (HR 1.03, 95% CI 0.81–1.31, p-value = 0.797). Conclusion: Real-world data suggest a 20% improvement in survival of metastatic melanoma since the introduction of ICI. The disproportionately high odds of metastatic disease at presentation in AA patients with melanoma suggest the need for a better understanding of the disease and improvement in care delivery.

• Intraspinal administration of allogenic bone marrow-derived mesenchymal stem cells (aBM-MSC) along with supportive therapy can be recommended as a therapeutic strategy for managing neural defects associated with non-deviating vertebral compression fractures in canine patients. • Percutaneous technique described in this communication is a non-invasive and efficient method that can be used for transplanting stem cell into the target site without the need of any imaging or guidance system. • Simplified implantation protocol that can be applied in the field level.

Dabigatran is an oral direct thrombin inhibitor that is approved for the prevention of stroke and systemic embolism in nonvalvular atrial fibrillation. Dabigatran has several advantages over warfarin including predictable pharmacokinetics and pharmacodynamics which eliminates the need for routine laboratory monitoring, superiority over warfarin in preventing stroke, or systemic embolism without having an increased risk of bleeding. However, as with any anticoagulant, there remains a real chance of bleeding, including major or life-threatening hemorrhage. Many physicians feel comfortable managing bleeding complications on older anticoagulants like warfarin and heparin, due to extensive experience with the medications along with antidotes to reverse their effects as well as established protocols for treating anticoagulant-associated hemorrhage. However, most physicians have limited clinical experience with dabigatran, there is no specific antidote for dabigatran reversal and there is a paucity of protocols, guidelines, and recommendations for how to manage dabigatran-associated hemorrhage. In this review, we present a case series of patients admitted to our institution for management of bleeding while receiving dabigatran. We retrospectively reviewed these cases to evaluate the efficacy and rationale of the various anticoagulation reversal strategies employed in the context of the existing evidence found in the literature. Specific focus is placed on the therapies utilized and the coagulation studies used to manage these patients.
