RESUMO
Stereotactic body radiotherapy is a highly effective form of radiation therapy for palliation of bone metastases, but it can also lead to rare but severe side effects, such as myonecrosis. According to the literature, the incidence of myonecrosis after stereotactic body radiotherapy is low and mostly dose dependent. It is crucial to consider the potential impact of immunotherapy and other systemic therapies in the assessment. The course of radiation myonecrosis can vary, and corticosteroids or vascular endothelial growth factor inhibitors may potentially play a role in its treatment. Herein, we report two patients presenting with myonecrosis after stereotactic body radiotherapy for bone metastasis.

Diabetic myonecrosis-a rare complication of long-standing, poorly controlled diabetes mellitus-typically presents with acute-onset muscle pain, is self-limiting, and responds well to conservative management. We report a case of diabetic myonecrosis in a 33-year-old man with hepatitis B-induced liver cirrhosis and type 2 diabetes who presented with abdominal distension and pain in the left thigh. Diabetic myonecrosis was diagnosed based on clinical presentation, radiological findings, magnetic resonance imaging and histopathological investigations; he was successfully treated conservatively with insulin and analgesics. Diabetic myonecrosis should be considered in the differential diagnosis of muscle pain in patients with diabetes.

Se presenta un paciente masculino de 29 años, mestizo, recluso, quien 7 días antes de haber sido remitido al servicio de urgencias del Hospital Universitario Amalia Simoni se había inoculado, en autoagresión, heces fecales en la pierna y el muslo derechos. Refirió dolor y presentaba gran toma del estado general. A la exploración física se constató aumento de volumen generalizado del miembro inferior derecho, con zonas de eritema marcado que alternaban con áreas de necrosis que incluso afectaban el abdomen bajo, aumento de la temperatura local; a la palpación, dolor intenso con amplia zona de crepitación subcutánea, además de bulas de contenido serohemático, pútrido, de olor fétido. La radiografía reveló aumento marcado de la opacidad de las partes blandas, bandas de gas a nivel del tejido celular subcutáneo y presencia de numerosas bulas sin toma ósea. Se decidió tratamiento quirúrgico multidisciplinario que incluyó la desarticulación en guillotina del miembro inferior derecho a nivel de la cadera y toilette amplia, medidas de soporte vital, y la combinación de clindamicina, vancomicina y meronem. La gangrena gaseosa es una infección fulminante de los tejidos blandos con una mortalidad elevada; la sospecha diagnóstica y el entendimiento de la fisiopatología mejoran el pronóstico. El soporte vital, el equilibrio del medio interno, el uso de antimicrobianos de amplio espectro y un tratamiento quirúrgico agresivo, disminuyen la mortalidad(AU)
A case of a 29-year convict mestizo male patient is presented here. This patient is referred to the emergency department of Traumatology at Amalia Simoni University Hospital, seven days after having self-inoculated with stool in his right leg and thigh as self-harm. The patient complained of pain and his general was very poor. Physical examination revealed generalized increase in volume of the right lower limb, with marked erythema areas alternating with areas of necrosis that were even affecting the lower abdomen; increased local temperature, tenderness, pain with subcutaneous crepitus in wide area were found, as well as bulls serohematic bulls, putrid, foul-smelling. Radiography reveals marked increase in opacity of the soft tissues, bands of gas at the level of subcutaneous tissue and the presence of numerous bulls without bone involvement. Multidisciplinary surgical treatment was decided including the guillotine disarticulation of the right leg to hip level and wide toilette, life support, and the combination of clindamycin, vancomycin, and meronem. Gas gangrene is a fulminant soft tissue infection with high mortality; the suspected diagnosis and understanding of the pathophysiology improve prognosis. Life support, balance the internal environment, the use of broad-spectrum antimicrobials and aggressive surgical treatment, reduce mortality(AU)
Un patient âgé de 29 ans, métis, reclus, référé au service d'urgences à l'hôpital universitaire "Amalia Simoni" dû à une automutilation (inoculation de selle dans la jambe et la cuisse droites), est présenté. Il a exprimé une douleur et une sensation de mal-être. Dans l'examen physique, on a pu constater une inflammation du membre inférieur droit; des zones érythémateuses très marquées alternant avec des zones nécrosées, même arrivant à l'abdomen bas; une augmentation de la température locale; une douleur violente avec une zone de crépitements à la palpation, et des bulles à contenu séro-hématique, putréfié et fétide. La radiographie a révélé une augmentation significative de l'opacité des parties molles, des bandes gazeuses au niveau du tissu cellulaire sous-cutané, et une présence de nombreuses bulles sans prise osseuse. On a décidé un traitement chirurgical pluridisciplinaire consistant à une désarticulation en guillotine du membre inférieur droit au niveau de la hanche et un curettage profond; des soins intensifs, et une combinaison de clindamycine, vancomycine et méropénème. La gangrène gazeuse est une infection fulminante des tissus mous avec un taux de mortalité très haut. Le diagnostic suspecté et la compréhension de la physiopathologie améliorent le pronostic. Les soins intensifs, l'équilibre du milieu intérieur, l'emploi d'antimicrobiens à large spectre et un traitement chirurgical agressif font réduire le taux de mortalité(AU)
