Split thickness skin graft versus application of the temporary skin substitute suprathel in the treatment of deep dermal hand burns: a retrospective cohort study of scar elasticity and perfusion.

Two therapeutic options for deep dermal hand burns are autologous split-thickness skin graft (STSG) following tangential excision and the application of the temporary wound dressing Suprathel following removal of burn blisters. We compared elasticity and perfusion of burn scars after both types of therapy at least one year after completion of treatment. A case series of 80 patients of our department with deep dermal hand burns between 2013 and 2018 was examined in the year 2019 at least one year after completion of treatment (24 females and 56 males with a median age of 47.6 years). The clinical assessment of the scar was performed with the Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS) and the objective assessment with suction cutometry (MPA 580) and an O2C device on both hands. Our statistical analysis showed no statistically significant differences for the R2 and R5 elasticity values between the two types of therapy. The 95% confidence intervals for the ratios of elasticity, and microcirculatory perfusion parameters and scar scale scores of burn scars to respective healthy areas of skin after STSG and Suprathel-therapy mostly covered 1. Subgroup analysis of R2 viscoelasticity and analyses with adjustments for scar compression therapy, nicotine consumption, age, palmar or dorsal localization of the burn scar and interactions of age with smoking and localization gave similar results. The adjusted analysis of SO2 showed statistically significant lower SO2 values, 9% less, after STSG compared to Suprathel treatment. Split-thickness skin graft following tangential excision and the application of Suprathel following removal of burn blisters may be equivalent options for treatment of deep dermal hand burns. To detect possible small differences, further studies with larger samples are required.

Reversible dilative cardiomyopathy after electrical injury: a case report.

BACKGROUND: Dilative cardiomyopathy is an uncommon cardiac complication of electric shock. CASE PRESENTATION: We report a case of a 12-year-old German boy with a high voltage injury who developed a four-chamber dilative cardiomyopathy, which was diagnosed on the 13th week postburn. One year after the accident, echocardiography showed a normal function of his heart with 64% ejection fraction and normal cavities' dimensions. CONCLUSIONS: Despite the fact that dilative cardiomyopathy is not very common in electrical injuries but can be fatal, a prolonged echocardiography follow-up for patients with electrical injury could be recommended. Until now this case is the first child with severe burns after electrocution, who developed a reversible dilative cardiomyopathy.

A Rare Manifestation of Primary Bone Lymphoma: Solitary Diffuse Large B-Cell Lymphoma of the Little Finger.

Solitary primary non-Hodgkin bone lymphoma of the hand is a rare entity with only 3 cases reported in the literature. We report the case of a 77-year-old patient with isolated large B-cell bone lymphoma of the proximal phalanx of the little finger without rheumatoid arthritis or methotrexate treatment. The patient was treated with digital amputation and at 6 months' follow-up showed no relapse or dissemination of the disease.
