Nefrectomia Radical e Nefroureterectomia Laparoscópica "Hand-Assited": a Experiência dos Primeiros 21 Casos

Objectivos: Os autores apresentam a sua casuística com os primeiros 21 casos submetidos a nefrectomia radical e nefroureterectomia laparoscópica "hand- assisted" e laparoscópica pura. Material e Métodos: Entre o período de Janeiro 2003 a Junho de 2004 procedeu-se à realização de nefrectomia radical e nefroureterectomia laparoscópica em 21 doentes com o diagnóstico clínico de carcinoma de células renais e de carcinoma de células de transição do trato urinário alto. Optámos pela assistência da mão apenas quando útil ou necessário. Realizamos 16 nefrectomias radicais laparoscopicas "hand-assisted", 2 nefroureterectomias radicais laparoscopicas "hand- assisted" com desincer- ção endoscópica do meato ureteral e 3 nefrectomias radicais laparoscopicas "puras". A idade média deste grupo foi de 62 anos.O diâmetro médio da massa renal foi de 4,8 cm. O diagnóstico anatomo-patológico revelou a existência de 17 carcinomas de células renais, 2 carcinomas de células de transição, 1 hemangioma e 1 quisto renal complicado. Tivemos uma taxa de conversão de 5%, e a duração da cirurgia foi de 1,46 horas. O follow- up destes doentes variou entre 1 e 2 anos, não se tendo verificado quaisquer recidivas. Nesta série houve um re-internamento. Conclusão: a nefrectomia radical laparoscópica "hand-assisted" e a nefroureterectomia laparoscópica "hand-assisted" são exequíveis sendo a curva de aprendizagem relativamente curta. A taxa de complicações é baixa.

A 63-Year-Old Woman Presenting with a Synovial Sarcoma of the Hand: a Case Report

INTRODUCTION: Synovial sarcoma is a high-grade, soft-tissue sarcoma that most frequently is located in the vicinity of joints, tendons or bursae, although it can also be found in extra-articular locations. Most patients with synovial sarcoma of the hand are young and have a poor prognosis, as these tumors are locally aggressive and are associated with a relatively high metastasis rate. According to the literature, local recurrence and/or metastatic disease is found in nearly 80% of patients. Current therapy comprises surgery, systemic and limb perfusion chemotherapy, and radiotherapy. However, the 5-year survival rate is estimated to be only around 27% to 55%. Moreover, most authors agree that synovial sarcoma is one of the most commonly misdiagnosed malignancies of soft tissues because of their slow growing pattern, benign radiographic appearance, ability to change size, and the fact that they may elicit pain similar to that caused by common trauma. CASE PRESENTATION: We describe an unusual case of a large synovial sarcoma of the hand in a 63-year-old Caucasian woman followed for 12 years by a multidisciplinary team. In addition, a literature review of the most pertinent aspects of the epidemiology, diagnosis, treatment and prognosis of these patients is presented. CONCLUSION: Awareness of this rare tumor by anyone dealing with hand pathology can hasten diagnosis, and this, in turn, can potentially increase survival. Therefore, a high index of suspicion for this disease should be kept in mind, particularly when evaluating young people, as they are the most commonly affected group.

Hand, Foot, and Mouth Syndrome in an Immunocompetent Adult: a Case Report

BACKGROUND: Hand, foot, and mouth syndrome (HFMS) is a common acute illness. It is characterized by mild clinical symptoms including fever, blisters, and sores in the mouth and on the palms and soles following a 3- to 7-day incubation period. This syndrome is rarely seen in adults. CASE PRESENTATION: A 35-year-old male Caucasian patient had a history of multiple episodes of acute pharyngitis, hypertension, hypercholesterolemia, and occasional abdominal pain. He presented with polyarthralgia in the knees and hands and odynophagia, followed by fever, oral mucosal aphthous lesions, and vesicles on the palms and soles. Three weeks after presentation, he was admitted to the emergency room with acute myocarditis. The in-hospital evaluation revealed positive serology for coxsackie A9 (1:160), positive anti-transglutaminase and anti-gliadin antibodies, normal immunoglobulins, and human immunodeficiency virus negativity. CONCLUSION: We herein describe a case of HFMS that was associated with coxsackie A9 infection complicated by acute myocarditis. Although an association between celiac disease and HFMS has not been described, this patient's immunologic disruption could have favored the development of infection and ultimately HFMS.
