ResumoOs sarcomas ósseos e das partes moles consistem em grupo heterogêneo de neoplasias malignas de origem mesenquimal que podem ocorrer em qualquer faixa etária. O estadiamento preciso destas lesões determina as melhores estratégias terapêuticas e estimativas de prognóstico. Dois sistemas de estadiamento são os mais frequentemente empregados no manejo destas neoplasias: o sistema proposto pelo grupo da Universidade da Flórida, liderado pelo Dr. William F. Enneking (1980), adotado pela Musculoskeletal Tumor Society (MSTS) e o sistema desenvolvido pela American Joint Committee on Cancer (AJCC) (1977) que se encontra em sua 8a edição (2017). O presente artigo busca atualizar o leitor a respeito do estadiamento dos sarcomas ósseos e das partes moles que acometem o sistema musculoesquelético.

Os autores avaliam os resultados de 35 procedimentos de descompressão cirúrgica do nervo ulnar realizados em 28 pacientes hansênicos. Os parâmetros utilizados incluíram a escala analógica visual, a escala comportamental, a avaliação da força muscular, a estesiometria e a avaliação do efeito do procedimento no que tange à diminuição da corticoterapia no pós-operatório. Observou-se resolução imediata da dor após a realização da cirurgia, melhora da força muscular em metade dos pacientes, melhora da sensibilidade em metade dos pacientes. A diminuição da dosagem da prednisona após a cirurgia foi constante e significativa após a operação.

ResumoA evolução na avaliação por imagens dos sarcomas musculoesqueléticos contribuiu para melhora significativa no prognóstico e na sobrevida dos portadores destas neoplasias. A caracterização precisa destas lesões, mediante utilização das modalidades de imagem mais adequadas a cada condição clínica apresentada, é de suma importância no delineamento da abordagem terapêutica a ser instituída, com impacto direto sobre os desfechos clínicos. O presente artigo busca atualizar o leitor a propósito das metodologias de imagem no contexto da avaliação local e sistêmica dos sarcomas ósseos e das partes moles.

SUMMARY OBJECTIVES: To describe the incidence by gender and region, lethality, and costs associated with the treatment of femoral fractures in the elderly (≥ 60 years) hospitalized in the Unified Health System (SUS) of Brasil between 2008 and 2018. METHODS: This is a cross-sectional, descriptive, retrospective study of hospitalizations of elderly people due to femoral fractures by analyzing secondary data obtained from the SUS Hospital Information System (SIH/SUS) between 2008 and 2018; for calculation of epidemiological coefficients, we used information from demographic censuses (2000 and 2010) of the Brazilian Geography and Statistics Institute (IBGE). RESULTS: A total of 478,274 hospitalizations were recorded in the period; the incidence was 1.7 times higher in females (overall average of 274.91/100,000 for women and 161/100,000 for men). The Southeast region had the highest absolute number of hospitalizations and the South region presented the highest annual overall average incidence (224.02/100,000). The average annual cost for SUS for the treatment of femoral fractures in the elderly was R$ 99,718,574.30. CONCLUSIONS: In the evaluated period (2008-2018), femoral fractures in the elderly had a high incidence (478,274 hospitalizations; 224.02 cases/100,000 elderly), a predominance of females (1.7F/1.0M), a higher absolute number of hospitalizations in the Southeast region and a higher incidence in the South region; the lethality was high (an increase of 17.46%; overall mean coefficient of 4.99%/year); and the costs for the SUS were huge (an increase of 126.24%; average annual expenditure of R$ 99,718,574.30).

We will study the influence of low intensity and frequency surface peripheral electrical stimulation (PES) on nerve regeneration of digital nerve injuries of the hand after its surgical repair in humans. Participants will be patients with acute traumatic peripheral nerve injury referred to the Hand Surgery Service of the General Hospital of the State of Bahia, a reference service in the state. These patients will undergo surgery followed by PES in the immediate postoperative period. After hospital discharge, they will be followed up on an outpatient basis by researchers, who will remotely supervise a physiotherapy program. Our hypothesis is that PES will positively influence the recovery of sensory function in patients undergoing neurorrhaphy of digital nerves of the hand.

Tumors traditionally classified as parachordomas are rare, usually indolent, soft tissue neoplasms. This case report describes a 6-year-old girl with a mass in her left forearm measuring 11 x 6 cm. Foci of moderate nuclear atypia and various areas of necrosis were found in the tumor. Lung metastases were detected 3 months after diagnosis. Immunophenotyping revealed a strong, diffuse expression of pancytokeratin, S-100 protein, vimentin, glial fibrillary acidic protein and focal expression of chromogranin A. This is the fifth documented report on cases of metastasized parachordomas. It is rare for these neoplasms to show such aggressive behavior; moreover, immunoreactivity to chromogranin A is unexpected in these tumors. The relationship between the so-called parachordomas and soft tissue myoepithelioma/mixed tumors is discussed, including the recently defined pediatric myoepithelial carcinoma.
