Trichoscopy as a diagnostic tool in trichorrhexis invaginata and Netherton syndrome.

Netherton syndrome is a rare autosomal recessive disease characterized by erythroderma, ichthyosis linearis circumflexa, atopy, failure to thrive and a specific hair shaft abnormality called trichorrhexis invaginata or bamboo hair, considered pathognomonic. We report the case of a 4-year-old boy with erythroderma since birth, growth deficit and chronic diarrhea. Trichoscopy was used to visualize typical bamboo and "golf tee" hair and of key importance to diagnose Netherton syndrome. We suggest the use of this procedure in all children diagnosed with erythroderma.

Infecções em cateter de hemodiálise: aspectos microbiológicos e de resistência em uma unidade de referência de Belém / Infections in catheter for hemodialysis: microbiological and resistance aspects in a reference unit of Belem

OBJETIVO: Descrever o perfil de infecção e resistência de cateter de hemodiálise da Fundação Hospital de Clínicas Gaspar Vianna, referência em nefrologia. MÉTODOS: Trata-se de um estudo desenvolvido na Fundação Hospital de Clínicas Gaspar Vianna, no período de Janeiro de 2011 a Dezembro de 2012, uma amostra de 164 pacientes onde foram analisados aspectos clínicos de infecção, além de dados de culturas de SWAB, ponta de cateter e hemoculturas. RESULTADOS: De 164 casos notificados de infecção de cateter de hemodiálise, obtiveram-se os seguintes resultados: a cultura de SWAB, 85,7% dos casos foram positivos, Ponta de Cateter 86,1% positivos e Hemocultura 64,5% positivos. Observou-se que o agente mais frequente nas culturas SWAB, Ponta de Cateter e Hemocultura foi o Staphylococcus aureus. No total de hemoculturas positivas este agente foi o mais frequente, seguido do Staphylococcus coagulase negativo (SCN). Ambos os agentes se mostraram sensíveis a terapêutica com oxacilina e ciprofloxacinano ambiente hospitalar estudado. CONCLUSÃO: O perfil de infecção encontrado no vigente estudo, faz com que possamos inferir que a principal causa das infecções de cateteres de hemodiálise estejam relacionadas a manipulação desses dispositivos pela equipe hospitalar e a própria colonização bacteriana no sítio de inserção. Chamou atenção abaixa incidência de germes hospitalares encontradas na pesquisa...

OBJECTIVE: To describe the profile of infection and resistance of hemodialysis catheter Hospital Foundation Clinical Gaspar Vianna, a reference in nephrology. METHODS: This is a study conducted at the Clinical Hospital Foundation Gaspar Vianna,in the period January 2011 to December 2012, a sample of164 patients whose clinical features of infection were analyzed, and data from cultures SWAB tip catheter and blood cultures. RESULTS: Of 164 cases of infection of hemodialysis catheter,we obtained the following results: the culture of SWAB, 85.7%of cases were positive, Tip Catheter 86.1% positive and 64.5% positive blood culture. It was observed that the most frequenta gent in cultures SWAB, catheter tip and blood culture was Staphylococcus aureus. Positive blood cultures in total this agent was the most frequent, followed by the Staphylococcus coagulase negativo (SCN). Both agents were sensitive to oxacillin and ciprofloxacin therapy in the hospital studied. CONCLUSION: The profile of infection found in the current study means that we can infer that the main cause of infections in hemodialysis catheters are related to manipulation of such devices by the hospital staff and bacterial colonization at the insertion site itself. Drew attention to the low incidence of hospital germs found in the study...
