ABSTRACT

As porfirias são doenças incomuns e de herança genética na maior parte doscasos. As porfirias são divididas em eritropoiéticas, hepáticas agudas e hepáticas crônicas. Os subtipos de maior relevância clínica são a porfiria cutânea tarda e a porfiria intermitenteaguda. O diagnóstico das porfirias pode ser bastante difícil, dada a sobreposição de quadros clínicos e achados bioquímicos. A precisão do diagnóstico depende da dosagem de porfirinasurinárias e fecais, da análise da atividade enzimática de eritrócitos e, eventualmente, da pesquisa de mutações. O objetivo do presente artigo é realizar revisão literária das porfirias,com ênfase no diagnóstico e tratamento de seus diversos subtipos...


Porphyrias are uncommon diseases that have genetic inheritance in the majorityof the cases. Porphyrias are divided in: erythropoietic porphyria, acute hepatic porphyria and chronic hepatic porphyria. The subtypes with major clinical relevance are porphyria cutaneatarda and acute intermittent porphyria. Diagnosing porphyrias may be quite difficult, as there is significant overlapping between clinical and biochemical findings. The diagnosis depends on the measurement of urinary and fecal porphyrins, enzymatic analysis of erythrocytes and, eventually, analysis of mutations. The main purpose of this article is to make a review of porphyrias, with emphasis on diagnosis and treatment of its several subtypes...

ABSTRACT

A anemia ferropriva grave secundária à hemorragia digestiva por angiodisplasias intestinais representa um grande desafio terapêutico. Comumente, as ectasias vasculares são múltiplas e dispersas ao longo do intestino, limitando a eficácia do tratamento hemostático local. Nos últimos anos houve significativo avanço no tratamento anti-angiogênico sistêmico das angiodisplasias intestinais, sendo talidomida a droga mais empregada para tal fim. Relatamos o caso de uma paciente de 49 anos com angiodisplasias intestinais secundárias a síndrome CREST (Calcinose, Raynaud, Dismotilidade Esofágica, Esclerodactilia e Telangiectasias). A paciente apresentava quadro de melena recorrente e alta necessidade transfusional, e não obteve resposta clínica após realização de enteroscopia e eletro-coagulação das lesões com plasma de argônio. Após a introdução de talidomida 100mg ao dia, a paciente evoluiu de forma bastante satisfatória. O caso apresentado neste texto, além de demonstrar sucesso da talidomida no tratamento de angiodisplasias intestinais refratárias à eletro-coagulação com plasma de argônio, também revela eficácia da droga na situação específica da síndrome CREST. Tal fato pode ser de grande valia quando da abordagem de hemorragia intestinal por angiodisplasias nesses pacientes, representando nova opção terapêutica...


The severe ferropenic anemia secondary to digestive bleeding due to intestinal angiodisplastic lesions represents a great challenge. Commonly, angiodisplastic lesions are multiples and disperse through the intestine and that fact limits local treatments. Over the last years, there was a great advance in the antiangiogenic treatment of intestinal angiodisplastic lesions and thalidomide was the most employed drug for this purpose. We report a case of a 49 year-old patient with intestinal angiodisplastic lesions due to CREST syndrome (Calcinosis, Raynaud phenomenon, Esophageal dysmotility, Sclerodactyly, and Telangiectasia). The patient presented repeated episodes of digestive bleeding and did not achieve clinical improvement after enteroscopy and argon plasma coagulation. The treatment consisting of the introduction of thalidomide 100mg per day demonstrated success. The case presented in this text reveals success in the use of thalidomide in the treatment of intestinal angiodisplastic lesions, probably representing a new therapeutic option...

ABSTRACT

INTRODUCTION: Head trauma is an important consequence of child abuse. Specific pathophysiological mechanisms in child abuse are responsible for the ''whiplash shaken-baby syndrome'', which would favour the occurrence of intracranial hemorrhages. CASE REPORT: We report the case of a child who developed epidural hematoma following minor-intensity head trauma. Initial diagnosis of child abuse was made, but subsequent investigation led to the diagnosis of hemophilia A. CONCLUSION: Even though epidural hematoma is not closely associated with child abuse, this aethiology must always be considered when the reported trauma mechanism is out of proportion to the magnitude of the encountered lesions
