Caracterización de fracturas abiertas de tibia / Characterization of Open Tibial Fractures

Introducción: Las fracturas diafisiarias de la tibia son las que con mayor frecuencia encuentran los cirujanos ortopédicos en su práctica habitual. La fractura expuesta de tibia es una urgencia quirúrgica que requiere desbridamiento, lavado, reducción y estabilización de los fragmentos óseos lo antes posible, e inicio de la administración de antibióticos profilácticos. Objetivo: Caracterizar los pacientes con fractura expuesta de tibia grado II y IIIA, tratados mediante estabilización con clavo acerrojado intramedular, identificando mecanismo de producción, número de intervenciones quirúrgicas por paciente, así como las principales complicaciones encontradas. Método: Estudio observacional, descriptivo, ambispectivo y de corte transversal en pacientes con fractura abierta de tibia, tratados quirúrgicamente con clavo acerrojado intramedular. Resultados: La edad de los pacientes osciló entre 21 y 69 años. Predominó el sexo masculino (65,4 porciento), la mayor causa traumática fueron los accidentes en la vía pública (37 pacientes); predominaron las fracturas del tercio medio abiertas grado IIIA con estadía hospitalaria menor de 10 días, y complicaciones en la tercera parte de los pacientes. Conclusiones: Se observó mayor incidencia en pacientes masculinos en edades comprendidas entre 18 y 29 años por accidentes del tránsito. La localización habitual fue el tercio medio y más de la mitad fueron clasificadas como grado IIIA de la tipología de Gustilo y Anderson(AU)

Introduction: Diaphyseal fractures of the tibia are those most frequently treated by orthopedic surgeons in their common practice. The exposed fracture of the tibia is a surgical emergency that requires debridement, lavage, reduction and stabilization of the bone fragments as soon as possible, and initiation of the administration of prophylactic antibiotics. Objective: To characterize patients with grade II and IIIA exposed tibial fracture, treated by stabilization with an intramedullary nail, identifying production mechanism, number of surgical interventions per patient, as well as the main complications found. Method: An observational, descriptive, ambispective and cross-sectional study in patients with an open fracture of the tibia treated surgically with an intramedullary locking nail. Results: The age of the patients ranged between 21 and 69 years. Male sex predominated (65.4 percent), the major traumatic cause was accidents on public roads (37 patients); Grade IIIA open middle third fractures predominated with hospital stays of less than 10 days, and complications in a third of the patients. Conclusions: High incidence was observed in male patients between the ages of 18 and 29 due to traffic accidents. The usual location was the middle third and more than half were classified as grade IIIA of Gustilo and Anderson typology(AU)

Epidemiology of Acne Vulgaris in 18-Year-Old Male Army Conscripts in a South Brazilian City.

BACKGROUND: Prevalence of acne varies worldwide. Several factors (age, skin color, body fat, diet, and smoking) have been investigated as risk factors. OBJECTIVE: A total of 2,201 18-year-old males living in Pelotas, South Brazil, were evaluated in order to examine the prevalence of acne and associated factors. METHODS: A cross-sectional population-based study was conducted. A dermatologist performed the clinical examination of the face and trunk for identification of acne lesions. Acne was evaluated as clinically noninflammatory, inflammatory, and acne with both types of lesions. Skin color, schooling, height, smoking, skinfolds, waist circumference, BMI, and dietary dairy intake were the independent variables used. RESULTS: A response rate of 97.2% was obtained. Individuals without any acne lesion were 241 (10.9%); 161 (7.3%) only had noninflammatory lesions, 404 (18.4%) only inflammatory lesions; and 1,395 (63.4%) presented both types of lesions. In multivariate analysis, the type of lesions was different in light and dark skin phototype adolescents, with more common inflammatory lesions in the light phototype and noninflammatory ones in the dark phototype patients. Height was directly associated with the occurrence of all types of acne, whereas lower fat mass was associated with the occurrence of noninflammatory acne. While daily consumption of whole milk or yogurt was found to be associated with inflammatory acne in crude analysis, the association with milk was not detected and that with yogurt was low in multivariate analysis. CONCLUSION: Our results suggest that future studies should explore determinants of noninflammatory and inflammatory acne separately, especially if mixed populations are studied.

Sexualidades interditadas: loucura e gênero masculino / Forbidden sexualities: madness and the male gender

Identifica e estuda as sexualidades e afetividades masculinas interditadas e aprisionadas nos hospícios brasileiros, durante as primeiras décadas republicanas. Busca-se problematizar a idéia de que os comportamentos sexuais e afetivos não teriam grande relevância na construção de perfis masculinos considerados 'desviantes' e/ou 'patológicos', por meio da análise de registros psiquiátricos da época. Trata-se, pois, de propor uma reflexão que desloque o eixo da análise para as especificidades de gênero que determinam as diferentes feições assumidas pelos 'distúrbios mentais' atribuídos a certos comportamentos sexuais e afetivos.
