Angiosarcoma Arising in an Ovarian Fibroma: A Case Report

Primary ovarian angiosarcoma is a very rare gynaecological sarcoma, with poor prognosis. These tumors are though to arise from carcinosarcomas, teratomas, or the ovarian vasculature and occur at any age. There are only a few cases reported in the international literature, most commonly associated to surface epithelial-stromal or germ cell tumours. Herein, the authors report the clinicopathologic features of an angiosarcoma arising in an ovarian fibroma. A 65-year-old patient was admitted with a palpable mass in the hypogastrium. Grossly, the removed ovary was completely replaced by a solid tumor mass. On histological analysis, the lesion revealed the typical histological features of angiosarcoma with sinusoidal patterns and anaplastic cells, admixed with spindle-shaped cells arranged in fascicles or in a storiform pattern, compatible with a fibroma. The vascular component was strongly immunopositive for CD31 and CD34. The patient was submitted to chemotherapy, and she was alive for two months after surgical proceedings

Reparo meniscal em crianças e adolescentes : uma revisão sistemática de resultados

OBJETIVO: Realizar uma revisão sistemática da literatura existente, a fim de analisar os resultados após o reparo meniscal na população pediátrica. MÉTODOS: Uma revisão sistemática foi realizada de acordo com as diretrizes PRISMA usando os Bancos de Dados de Análise Sistemática Cochrane, Registro Central Cochrane de ensaios controlados, MEDLINE Ovid e MEDLINE PubMed. Os critérios de inclusão foram os seguintes: estudos que relatam os resultados do reparo meniscal em pacientes com 18 anos ou menos, com um seguimento médio mínimo de 12 meses, idiomas português, espanhol ou inglês e estudos humanos incluindo 10 ou mais pacientes. RESULTADOS: Nossa pesquisa identificou 2534 títulos individuais. Após a aplicação dos critérios de inclusão e exclusão, foram incluídos oito estudos, avaliando 287 pacientes com lesões meniscais reparadas. Sete estudos foram classificados como nível de evidência IV e um nível III. O escore médio MINORS foi de 8,6 ± 1,4. O reparo meniscal incluiu todas as zonas meniscais e padrões de lesões. A lesão do ligamento cruzado anterior foi a lesão associada mais comum. As técnicas “inside-out” e “all-inside” foram predominantemente relatadas. A maioria dos pacientes relatou resultados bons a excelentes e teve sinais clínicos de cicatrização meniscal; as meniscectomias após reparação meniscal foram realizadas em apenas 44 casos. CONCLUSÃO: Lesões meniscais em pediatria não são incomuns. O reparo desta lesão foi associado com resultados bons a excelentes na maioria dos pacientes, independentemente do padrão de lesão, zona ou técnica. As complicações relatadas foram mínimas, no entanto, são necessários estudos de maior qualidade para confirmar os achados desta revisão sistemática. NÍVEL DE EVIDÊNCIA: Nivel IV, revisão sistemática de estudos nível III e nível IV.PURPOSE: To perform a systematic review of existing literature in order to analyze outcomes after meniscal repair in the pediatric population. METHODS: A systematic review was performed according to PRISMA guidelines using the Cochrane Database of Systematic Review, Cochrane Central Register of Controlled Trials, MEDLINE Ovid, and MEDLINE PubMed databases. Inclusion criteria were as follows: studies reporting the outcomes of meniscal repair in patients 18 years old or younger, with a minimum mean follow-up of 12 months, Portuguese, Spanish or English languages, and human studies including 10 or more patients. RESULTS: Our search identified 2534 individual titles. After application of the inclusion and exclusion criteria, 8 studies were included, evaluating 287 patients with repaired meniscal tears. Seven studies were classified as level of evidence IV and one level III. The mean MINORS score was 8.6 ± 1.4. Meniscal repair included all meniscal zones and tear patterns. Anterior cruciate ligament tear was the most common associated injury. The all-inside and inside-out techniques were predominantly reported. The majority of the patients reported good to excellent outcomes and had clinical signals of meniscal healing; meniscectomies following meniscal repair were performed in just 44 cases. CONCLUSION: Meniscal tears in pediatrics are not uncommon. Repairs of this injury were associated with good to excellent outcomes in most patients, regardless of the injury pattern, zone or technique. Reported complications were minimal, however, higher quality studies are needed to confirm the findings of this systematic review. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and Level IV studies

Posterior Capsulotomy of the Knee: Treatment of Minimal Knee Extension Deficit

The loss of knee extension, even if minimal, is disabling and considerably affects the individual's quality of life. This loss of extension can be a consequence of prior surgery, including a previous anterior cruciate ligament reconstruction. Although this loss of extension may be treated through an isolated arthroscopic procedure, a more severe case may warrant an invasive approach. In these cases, a posterior capsulotomy of the knee may be done if all conservative measures have been exhausted. This procedure has been proven to be safe and effective in the re-establishment of full extension in the setting of a minor flexion contracture of the knee. The purpose of this Technical Note was to describe our preferred technique when performing an open posterior capsulotomy of the knee for the treatment of minimal extension deficit
