Scurvy and Tinea Corporis Simulating Leukocytoclastic Vasculitis.

ABSTRACT: Leukocytoclastic vasculitis (LCV) is a small vessel inflammatory condition considered to be caused by circulating immune complexes and often occurs after an acute infection or exposure to a new medication, although it may be associated with an underlying systemic disease or be idiopathic in nature. It is important to determine the etiology, identify the extent of the disease for early intervention and appropriate management, and treat and/or eliminate the underlying cause. Here, we report cases of scurvy and tinea corporis that presented with histopathologic features of LCV and had significant clinical improvement with treatment of the underlying etiologies. These cases emphasize that histopathologic features of early evolving LCV may be seen in other settings including scurvy and tinea corporis. Appropriate treatment of the underlying condition is important for optimized patient management.

Review of the Current Medical and Surgical Treatment Options for Microstomia in Patients With Scleroderma.

BACKGROUND: Most patients with scleroderma suffer from microstomia, which can have debilitating consequences on their quality of life. Unfortunately, treatment options remain limited. No specific guidelines exist; hence, microstomia remains a challenge to treat in this patient population. OBJECTIVE: This review aims to evaluate the different medical and surgical treatment modalities currently available for microstomia in patients with scleroderma and make recommendations for future research. MATERIALS AND METHODS: A search of PubMed, Ovid MEDLINE, and Ovid Embase was conducted to identify articles discussing the treatment of microstomia in scleroderma. Twenty articles discussing surgical therapy and one article discussing medical therapy were reviewed. RESULTS: Mostly because of a scarcity of high-level evidence, no individual therapy has documented long-term efficacy. Some treatments demonstrate positive results and warrant further research. CONCLUSION: Given the variability of results, specific recommendations for the treatment of microstomia in patients with scleroderma are difficult to establish. A multifaceted approach that includes surgical and medical therapy is likely the best option to improve oral aperture in this patient population. Surgical treatments such as neurotoxins, autologous fat grafting, and ultraviolet A1 phototherapy may hold the most potential for improvement.

Thromboelastometry analysis of severe North American pit viper-induced coagulopathy: A case report.

CASE DETAILS: A 51-year-old man presented with rapid onset encephalopathy and respiratory failure after a suspected intravascular envenomation from a North American pit viper. The patient received antivenom and was transferred to a tertiary care facility where he had cardiovascular collapse and persistent coagulopathy requiring 28 vials of Crotalidae polyvalent immune Fab antivenom for initial control and six vials for maintenance. The patient's coagulopathy was monitored using "traditional" measures (platelets, fibrinogen, and prothrombin time/international normalized ratio) and rotational thromboelastometry (ROTEM®). The patient also subsequently developed intestinal necrosis requiring exploratory laparotomy with ileum and colonic resections, and anuric renal failure requiring continuous renal replacement therapy. After coordinated multidisciplinary management, he was discharged to an acute inpatient rehabilitation on hospital day 25 and has since made a full recovery. DISCUSSION: In the setting of a severe intravascular pit viper envenomation, thromboelastometry correlated well with "traditional" measures. During recovery, ROTEM® demonstrated measurable improvements in the extrinsic coagulation pathway while the INR remained between 1.5 and 1.6. Patient's intestinal necrosis may have resulted from microvascular thrombosis due to Crotalinae venom. The patient's ultimate recovery necessitated a coordinated multidisciplinary effort. ROTEM® abnormalities after North American pit viper envenomation may be more sensitive than "traditional" measures and may have prognostic value to determine the severity of envenomation, but further research to define its utility is required.
