Objective: To evaluate the efficacy of platelet-rich plasma regarding healing, pain and hemostasis after total knee arthroplasty, by means of a blinded randomized controlled and blinded clinical study. Methods: Forty patients who were going to undergo implantation of a total knee prosthesis were selected and randomized. In 20 of these patients, platelet-rich plasma was applied before the joint capsule was closed. The hemoglobin (mg/dL) and hematocrit (%) levels were assayed before the operation and 24 and 48hours afterwards. The Womac questionnaire and a verbal pain scale were applied and knee range of motion measurements were made up to the second postoperative month. The statistical analysis compared the results with the aim of determining whether there were any differences between the groups at each of the evaluation times. Results: The hemoglobin (mg/dL) and hematocrit (%) measurements made before the operation and 24 and 48hours afterwards did not show any significant differences between the groups (p > 0.05). The Womac questionnaire and the range of motion measured before the operation and up to the first two months also did not show any statistical differences between the groups (p > 0.05). The pain evaluation using the verbal scale showed that there was an advantage for the group that received platelet-rich plasma, 24hours, 48hours, one week, three weeks and two months after the operation (p < 0.05). Conclusions: In the manner in which the platelet-rich plasma was used, it was not shown to be effective for reducing bleeding or improving knee function after arthroplasty, in comparison with the controls. There was an advantage on the postoperative verbal pain scale.

Melanoma subungueal in situ tratado com cirurgia funcionalHamilton Ometto StolfI, Hélio Amante MiotI, Nilton de Ávila ReisIIDepartamento de Dermatologia e Radioterapia, Universidade Estadual Paulista (Unesp)INTRODUÇÃOO melanoma subungueal representa aproximadamente 2% a 3% dos melanomas cutâneos em pacientes caucasianos1 e 20% em pacientes negros2 ou asiáticos.3A exposição solar, tida com principal fator de risco para o melanoma cutâneo,4 parece desempenhar papel secundário no desenvolvimento da variante subungueal,5 uma vez que a radiação ultravioleta dificilmente penetra no leito ungueal. Além disso, nevos subungueais como lesões precursoras são extremamente raros.6Os polegares e háluces são os mais acometidos, sendo o polegar responsável por 56% dos casos entre todos os dedos e o hálux por 86% dos dedos dos pés.7A confirmação do diagnóstico é feita a partir do exame anatomopatológico da lesão, geralmente localizada na matriz ou leito ungueal. A verificação histológica do melanoma subungueal é frequentemente postergada por conta do atraso no diagnóstico clínico,8-10 gerando piora do prognóstico.O prognóstico geralmente é ruim: as taxas de sobrevida real de cinco anos variam entre 16% a 20%, podendo atingir até 80% se consideradas taxas de sobrevida estimada.2,3,11-18RELATO DE CASOPaciente de 44 anos, do sexo feminino, professora, com queixa de aparecimento de mancha na unha do hálux direito há cinco anos. Relata aumento progressivo lento na largura da faixa. Ao exame dermatológico, apresentava faixa de melanoníquia extensa, irregular, bordas mal definidas e estria de pigmentação mais acentuada em uma das margens do leito ungueal do hálux direito (Figura 1). Exame dermatoscópico (aparelho Dermalite II Pro, aumento de 10 vezes) confirmou faixas irregulares e cores variadas de hiperpigmentação.Foi realizada a avulsão parcial da lâmina ungueal e incisão na prega ungueal lateral para visualização do local da origem da pigmentação no leito ungueal,

We investigated estradiol benzoate effects on oocytes/embryos recovery rate and the influence of this drug on the hematopoietic system. Twenty four bitches were divided in two groups, Group I, 12 females that received a single shot of estradiol benzoate, 0.2 mg/kg intramuscularly, between 2 and 7 days after the date of the last mismating or insemination and, Group II (control), 12 bitches that received 0.2 ml/kg of oily diluent, in corresponding dates. The bitches were ovary-hysterectomized and the uterus/oviduct were isolated and flushed with a PBS, heparin and polyvinyl alcohol solution. Oocytes and embryos were quantified and classified according to their stage of development. Blood counts were performed on M1 (before drug administration), M2 (15 days after drug administration) and M3 (40 days after drug administration). Pearson correlation coefficient was used to analyze the variable retrieval structures, while Fisher exact test was used for the analysis of embryonic viability. ANOVA was used to analyze repeated measurements and Tukey test for hematological parameters. All tests were performed at 5% significance level. The recovery rate of total structures in group I was lower (22.88%) than group II (65.85%). A lower embryo recovery (ratio 3: 52) rate and a greater number of degenerated structures (ratio 11: 1) were observed in group I. Hematological parameters showed significant difference in erythrocytes, hematocrit and hemoglobin concentrations 15 days after drug administration and difference in leukocytes concentration 40 days after using the medication in bitches of group I, however, at the end of the experiment all bitches had blood counts considered normal.
