Fratura de complexo zigomático ­ relato de caso / Zygomatic process fractures ­ case report

Dentre as fraturas maxilofaciais, o complexo zigomático é o mais acometido, seguido das fraturas nasais e das fraturas Mandibulares O objetivo deste trabalho é apresentar um relato de caso de fratura de complexo zigomático tratada pelo serviço de Cirurgia e Traumatologia Bucomaxilofacial, como também descrever as formas de diagnóstico e tratamento clínico e cirúrgico.

Among the maxillofacial fractures, the zygomatic complex is most affected followed by nasal fractures and mandibular fractures. The objective of this work is to present a case report of a zygomatic complex fracture treated by the bucomaxillofacial Surgery and Traumatology service, as well as to describe the forms of diagnosis, clinical and surgical treatment.

Degradabilidade da fibra do bagaço de cana-de-açúcar tratado por soluçöes alcalinas, pela técnica dos sacos de náilon "in situ" / Fiber degradability of sugar cane bagasse treated by alkaline solutions, through the \"in situ\" nylon bag technique

O bagaço de cana-de-açúcar (BCA) foi submetido a três tratamentos, sendo imerso em uma das seguintes soluçöes: (A) de NaOH (2 por cento peso/volume), (B) de cinzas de madeira (30 por cento peso/volume) e (C) em água. E constituiu 60 por cento da matéria seca das dietas, junto com 40 por cento de concentrados (milho, gräo de soja e farelo de algodäo), fornecidas em ensaios de degradabilidade ruminal para 6 bovinos com fístulas ruminais. O delineamento foi o "change-over" (3x3), adotando-se a técnica de sacos de náilon "in situ". A degradabilidade da MS às 48h foi (p<0,05): (A)=75,14 por cento, (B)=34,20 por cento, (C)=24,26 por cento. A degradabilidade da fraçäo FDN do BCA foi sempre maior (p<0,05) no tratamento (A) do que nos demais; já a degradabilidade no tratamento B foi maior (p<0,05) do que no C, às 72 e 96h. A degradabilidade da FDN às 48h de incubaçäo foi: (A)=74,01 por cento, (B)=41,61 por cento e (C)= 35,72 por cento. Concluiu-se que os tratamentos alcalinos (soda e cinzas de madeira) melhoram a degradabilidade ruminal do BCA, sendo a soda superior às cinzas

[Drash's syndrome and its variants. A report of 3 cases]. / Síndrome de Drash y sus variantes. Informe de 3 casos.

Three cases of Drash syndrome (DS) are presented. Two of them were 2 years old, the third one a newborn. Two are autopsy cases, one of the patients is alive. All three of them had nephrotic syndrome and renal failure, with mesangial sclerosis. All three had ambiguous genitalia, abdominal testes with variable degrees of dysgenesis and bilateral gonadoblastoma. Two cases had 46XY karyotype, in one case it was not performed. Two patients had nephroblastoma, one of them after several months of nephropathy, in the other it was the cause of consultation. The patient without nephroblastoma died at the age of 26 days with renal failure. We think that the original triad of DS: nephroblastoma, pseudohermaphroditism and nephropathy should be more precisely described and expanded to include related alterations in each one of its 3 elements: nephroblastomatosis, hamartomas, probably mesoblastic nephroma and pyelocaliceal malformations in addition to Wilms' tumor, variable disorders of sexual differentiation, gonadal dysgenesis and neoplasia, in addition to pseudohermaphroditism and superficial cortical renal dystrophy and increased reniculi, in addition to mesangial sclerosis. The various clinical forms of the syndrome are combinations of the triad in which a component can be missing and/or other related malformations be present. Chromosome anomalies are possibly responsible for this phenomena. Splitting into separate syndromes should not be done until the chromosome alterations and the regions and genes involved are identified.

[Chromosomal translocation (2;13) in disseminated rhabdomyosarcoma]. / Translocación cromosómica (2;13) en un rabdomiosarcoma diseminado.

A 12-year-old male with a disseminated alveolar rhabdomyosarcoma is reported. The diagnosis was difficult because of the clinical manifestations and the histological patterns of the bone marrow and a chest wall tumor. Diagnosis was confirmed through the histologic picture of a gum biopsy and the karyotype of the tumoral cells of the bone marrow. Chromosome study revealed a hypotetraploid cell line with the translocation (2;13) characteristic of this type of neoplasias. The usefulness of chromosome studies in solid tumors of childhood is emphasized.
