El diagnóstico histológico de los pólipos colorrectales determina la conducta que tomará el médico especialista con el paciente. Con la aparición de nuevos pólipos en los últimos años, la clasificación histológica se ha tornado más compleja y amplia. Nuestro objetivo es actualizar los conceptos en el diagnóstico histológico de pólipos de colon de una manera clara y de fácil comprensión, especialmente para gastroenterólogos y patólogos.
Histological diagnosis determines the clinical behavior of colorectal polyps. Recently new types of polyps have been described and the classification has become wider and more complex. Our aim is update the current concepts in the knowledge of colorectal polyps.

Ensaios para avaliar o potencial antibacteriano de Rhizophora mangle (mangue-vermelho), coletada no município de Conde, Bahia, foram realizados com cepas bacterianas Gram-positivas (Staphylococcus aureus ATCC 6538 e Micrococcus luteus ATCC 9341) e Gram-negativas (Echerichia coli ATCC 10536, Salmonella Cholerea-suis 10708, Klebsiela pneumoniae ATCC 700603 e Pseudomonas aeruginosa ATCC 15442). A atividade antibacteriana foi avaliada pelos métodos de difusão em disco e concentração inibitória mínima (CIM), e os resultados analisados estatisticamente. Os resultados do ensaio de difusão em disco mostraram diferença significativa quanto à sensibilidade dos micro-organismos frente aos extratos testados (p<0,05). A CIM do extrato da folha (313 µg mL-1) apresentou o melhor desempenho para inibir o crescimento das cepas Gram-positivas, enquanto o extrato da casca foi mais eficaz para as cepas Gram-negativas. De acordo com os dados levantados por este estudo, R. mangle apresentou propriedade antibacteriana para cepas Gram-positivas e Gram-negativas, podendo tornar-se alternativa terapêutica tanto para o uso popular quanto para a indústria farmacêutica.
Assays to evaluate the antibacterial potential of Rhizophora mangle (red mangrove), sampled at Conde Municipality, Bahia State, Brazil, were performed against Gram-positive (Staphylococcus aureus ATCC 6538 and Micrococcus luteus ATCC 9341) and Gram-negative (Echerichia coli ATCC 10536, Salmonella Cholerea-suis 10708, Klebsiela pneumoniae ATCC 700603 and Pseudomonas aeruginosa ATCC 15442) bacteria. Antibacterial activity was evaluated by disc diffusion and minimal inhibitory concentration (MIC) and results were statistically analyzed. The results of disc diffusion assay showed a significant difference as to the sensitivity of microorganisms against the tested extracts (p<0.05). The MIC of leaf extract (313 µg mL-1) indicated the best performance to inhibit the growth of Gram-positive strains, while bark extract had a better efficacy against Gram-negative strains. Based on the presented data, R. mangle showed antibacterial properties against both Gram-positive and Gram-negative strains and can be used as an alternative therapy for popular use or for the pharmaceutical industry.

A fifty year old male presented on the sixteenth post-operative day after leg surgery with abdominal pain and distension, difficulty to breathe and oliguria. He had bradycardia and hypotension. Electrocardiography (ECG) revealed junctional rhythm and there was biochemical evidence of hyperkalemia. This was attributed to non-steroidal anti inflammatory drug diclofenac sodium induced renal dysfunction.

Dieciseis pacientes en edad pediatrica, con sintomas y signos de faringoamigdalitis aguda fueron tratados con una suspension de bacampicilina, a razon de 25 mg por kg de peso y por dia, durante sete dias. El 75% de los pacientes tuvo curacion completa, 12,5% solo mejoria, un paciente (6.25%) abandono el tratamiento a causa del sabor y en otro mas se observo una falla terapeutica. El sabor fue juzgado excelente en 75% de los casos, bueno en 18.75% e inaceptable en 6.25%. Ningun efecto indeseable de importancia fue observado. Se concluye que la suspension de bacampicilina es util en el manejo ambulatorio del nino con faringoamigdalitis aguda, pues su sabor es aceptado facilmente, su eficacia terapeutica es alta y la incidencia de efectos indeseables es muy baja
