Researchers studying exogenous processes in developing countries have to deal with the problem of scarcity of rainfall data. With satellite measurements, such as those provided by the Tropical Rainfall Measuring Mission (TRMM), it may be possible to overcome this limitation. In this work we link the TRMM rainfall measurements with two examples of exogenous processes from southwest Angola: landslide processes, focused on the events at the Leba road in early 2011, and flow conditions, based on the water level determined in gauging stations from rivers Cavaco and Catumbela. It is demonstrated that major mass flow movements occur when specific TRMM rainfall thresholds are reached. Regarding the flow conditions, the water level in two gauging stations is strongly conditioned by other factors beside the atmospheric precipitation in their watersheds (retention and release of water from reservoirs, channel obstruction, etc.), but short term oscillations are closely linked with the rainfall in the proximity. TRMM data is found to be very useful for the analysis of specific extreme events or the patterns of behavior of natural systems and, consequently, constitute a valuable tool in natural risks assessment.

ResumoOs hemangiomas intramusculares (HIs) são tumores benignos de tecidos moles que representam menos de 1% de todos os hemangiomas. Esta entidade clínica raramente é considerada como diagnóstico diferencial nos casos de dor musculoesquelética. Uma paciente do sexo feminino, de 38 anos de idade, saudável, se apresentou ao nosso consultório com queixa de omalgia esquerda, com 8 meses de evolução, que limitava suas atividades diárias. Ela relatou o aparecimento de tumefação 4 meses antes da consulta. A paciente estava medicada com analgésico e antiinflamatório sem melhoria clínica. Ao exame objetivo, ela apresentava limitação da abdução do ombro esquerdo (0–90°). A paciente foi submetida a uma ressonância nuclear magnética (RNM) na qual foi detectada uma formação nodular bem circunscrita no músculo deltoide,. Em seguida, foi realizada uma biópsia que confirmou o diagnóstico de hemangioma. A paciente foi então encaminhada para a realização de escleroterapia. Os HIs normalmente são observados em pacientes jovens. O exame padrão-ouro para o diagnóstico é a RNM, que muitas vezes torna a realização de biópsia desnecessária. Em muitos casos, os HIs são assintomáticos e tendem a involuir com o tempo. Apesar da baixa frequência desta entidade clínica, é importante colocá-la como hipótese de diagnóstico em casos de dor crônica dos membros em pacientes jovens com má resposta terapêutica a antiinflamatórios e analgesia.

A bstract Leiomyoma is a benign soft tissue tumor originating from smooth muscle, rarely seen in the oral cavity, due to the scarcity of this tissue in the mouth. The tumor may occur at any age, without sex predilection. Rare reports of this lesion have been in pediatric patients. The lesion is typically asymptomatic and has slow growth, the final diagnosis is defined by histopathological and immunohistochemical examination. Treatment involves resection of the lesion. The lesion is classified histologically as solid leiomyomas, angioleiomyomas (AL), or epithelioid leiomyomas. We report the case of a 1-year-old female child with a painless papule on the hard palate. Histopathological examination revealed biphasic LA showing proliferation of spindle-shaped nuclear cells in straw-shaped bundles or a concentric design. This is the fourth documented case of AL in early childhood. How to cite this article Bezerra TMM, Chaves FN, Carvalho FSR, et al.
