Adversidade familiar e problemas comportamentais entre adolescentes infratores e não-infratores

O presente estudo comparou adolescentes infratores e não-infratores com relação a dois aspectos: grau de adversidade familiar e grau de concordância entre a autopercepção e a percepção dos pais sobre problemas de comportamento dos jovens. Participaram deste estudo 40 adolescentes, 23 atendidos no Centro de Atenção e Apoio ao Adolescente (UNIFESP) e 17 adolescentes considerados infratores sob intervenção da Vara da Infância e da Juventude da comarca de Santos. Os instrumentos utilizados foram o Child Behavior Checklist (CBCL), Youth Self Report (YSR) e o Índice de Adversidade Familiar de Rutter. O Índice de Adversidade Familiar do grupo de adolescentes infratores foi significativamente maior. Os resultados apontaram ainda que, embora a diferença não tenha sido estatisticamente significante, a porcentagem dos escores de discordância nas percepções sobre problemas de comportamento foi maior entre os adolescentes infratores e seus pais.

Desfecho dos casos de violência contra crianças e adolescentes no poder judiciário

Objetivos: Analisar, decorridos cinco anos da notificação, o desfecho dado pela Vara da Infância e da Juventude de Londrina (PR) aos casos de violência contra crianças e adolescentes; identificar os tipos de violência com maior taxa de encaminhamento à vara da Infância e Juventude. Métodos: Estudo descritivo, quantitativo, cuja população de estudo foram crianças e adolescentes de até 15 anos de idade, residentes em Londrina (PR), vítimas de violência notificada pelos Conselhos Tutelares à Vara da Infância e da Juventude, em 2002. Resultados: Dos 230 casos, dos quais 40,0% dos processos foram arquivados; 3,9% foram arquivados enquanto ainda inquéritos; em 1,7% houve condenação do réu; 31,7% dos processos encontravam-se em andamento. Conclusão: Os achados contribuem para ampliar o conhecimento das medidas de proteção adotadas pelo poder judiciário frente aos casos de violência contra crianças e adolescentes.

Tension band wire fixation for valgus osteotomies of the proximal femur: A biomechanical study of three configurations of fixation

Background. A variety of techniques can be used to achieve stabilization of femoral valgus osteotomies in children, but what is lacking is a versatile fixation system that associates stability and versatility at different ages and for different degrees of deformity. Methods. Mechanical tests of three configurations used to fix femoral valgus osteotomies, based oil the tension band wire principle, were carried out. A 30 degrees wedge valgus osteotomy was performed at the subtrochanteric level in 60 swine femurs and fixed with three different systems. In Group 1, two Kirschner wires (K wire) were introduced from the tip of the greater trochanter to the medial cortex, crossing the osteotomy. A flexible steel wire was anchored to the K wires into holes in the lateral cortex and tightened to form a tension band. The same setup was used in Group 2, but two additional smooth K wires were inserted into the lateral surface of the greater trochanter and driven to the femoral head with the distal extremities bent and tied around tile bone shaft. In Group 3, the fixation was similar to that in Group 2, but tile ascending K wires were introduced below the osteotomy level, crossing the osteotonly. Mechanical tests in bending-compression and torsion were used to access the stability. Findings. The torsional relative stiffness was 116% greater for Group 3 (0.27 N m/degree) and no significant difference was found between Group 1 (0.10 N m/degree) and Group 2 (0.12 N m/degree). The average torque was 103% higher for Group 3 (1.86 N m). Stiffness in bending-compression was significantly higher in Group 3 (508 x 10(3) N/m) than in Group 1 (211 x 10(3) N/m) and Group 2 (219 x 10(3) N/m). Interpretation. Fixation as used in Group 3 was significantly more stable, both in torsion and bending-compression tests, than tile other two techniques. (c) 2007 Elsevier Ltd. All rights reserved.

Does Trochanteric Transfer Eliminate the Trendelenburg Sign in Adults?

Premature closure of the proximal femoral growth plate results in coxa brevis, which usually is associated with insufficiency of the hip abductors. Distal and lateral transfer of the greater trochanter sometimes is recommended to correct this problem. Most of what is known arises from studies of children and adolescents. We asked whether this procedure in adults with coxa brevis would eliminate hip abductor insufficiency and would improve their hip function based on the Harris hip score (HHS). We prospectively followed 11 patients, aged 19 to 55 years (mean, 40 years) who had distal and lateral trochanteric transfer. All patients had pain and a positive Trendelenburg test before surgery. This test was performed at the latest followup by three observers and the interobserver reliability was determined by the kappa coefficient. The HHS was obtained before surgery and at the latest followup. The minimum followup was 25 months (mean, 52 months; range, 25-77 months). Insufficiency of the hip abductors was eliminated in seven (according to two observers) and eight (according to one observer) of the 11 patients after surgery; the kappa coefficient ranged from 0.79 to 1.0. The mean HHS improved from 64 points preoperatively to 76 points at the final followup. The two patients with preexisting severe osteoarthritis of the hip had the worst final scores and persisted with a positive Trendelenburg test at the final followup. Distal and lateral transfer of the greater trochanter can eliminate insufficiency of the hip abductors and improve joint function in adult patients with coxa brevis and we believe should be considered for patients without severe osteoarthritis of the hip.
