En la mayoría de las biopsias prostáticas el epitelio seminal se reconoce fácilmente, ya que muestra criterios histológicos característicos. Sin embargo, algunas biopsias pueden semejar lesiones prostáticas malignas o premalignas. Los propósitos de este estudio son analizar el aspecto histológico de las biopsias que simularon adenocarcinomas o lesiones prostáticas preneoplásicas; comentar su diagnóstico diferencial y conocer la frecuencia de epitelio seminal en biopsias prostáticas.

Summary Questionnaire responses from mothers 1,039 Lebanese 3–9 yr olds were used to study the effects of children's experiences in war on their emotional and social behaviour. Children who had experienced death of a family member, forced displacement of family, or destruction of home or had witnessed death (30% of sample) were about 1.7 times more likely than those who had not to exhibit nervous, regressive, aggressive and depressive behaviour reactions to a general war stress situation (shelling). Findings are discussed with respect to: (a) research relating stressful life events to onset of psychological disorder and (b) societal implications of youngsters' being repeatedly exposed to models of aggression and the violent resolution of interpersonal disputes.

The authors present a retrospective study based on a homogeneous series of 34 patients with burst fractures of the thoracolumbar junction, fixed using Cotrel-Dubousset instrumentation. These patients under-went instrumentation using a short construct of hooks and screws gripping the two vertebrae above the lesion (2HS) and screws and hooks gripping the first vertebra below the lesion (1SH). This construct was therefore called “2HS-1SH”. In order to evaluate just the material resistance after getting up, only the patients who were upright on the 4th day without a body cast and with no secondary anterior osteosynthesis were included in this study. Four patients showed some neurological symptoms on admission but recovery was so quick that they could be included in this study. Mean follow-up was 4 years 1 month (range 3 years 1 month and 6 years 2 months). Vertebral and regional kyphosis angles were measured preoperatively, postoperatively and at the final follow-up. Functional recovery and complications were analyzed. Mean vertebral kyphosis was 21.2° preoperatively, 3.8° postoperatively and 5.3° at the final follow-up. Regional kyphosis angles were respectively 19.2, 0.2, and 2.7°. We had two cases of deep suppuration, one early and the other late. None of the patients required analgesics for more than 6 months after the operation. Patients returned to work after 5 months on average. The authors concluded that fixation by screw-and-hook constructs is an effective way to stabilize thoracolumbar junction burst fractures.
