Resumo Objetivos: saber o local onde irá ocorrer o parto é um direito da gestante no Brasil e uma estratégia de organização da rede de atenção obstétrica. Este estudo tem como objetivo avaliar a distribuição dos partos dos nascidos vivos (NV) da Gerência Regional de Saúde (GERES) I do Estado de Pernambuco em 2012. Métodos: a partir das Declarações de Nascidos Vivos, foram investigados deslocamentos do município de residência da mãe e de ocorrência do parto. Foram construídos mapas de fluxo para o Recife e estimado o número esperado de NV com parto de risco habitual e de alto risco para os municípios da GERES I. Resultados: em 2012 apenas 50% dos NV da GERES I nasceram no município de residência da mãe. Em Recife ocorreram 1,5 vezes o número de partos esperados para o ano, sendo 56% de mães não residentes. Onze municípios da GERES I têm maternidade, mas nenhum responde ao volume esperado de partos de risco habitual. Conclusões: esta desestruturação da rede obstétrica viola o direito da mulher de saber com antecedência e construir vínculo com o local do parto. Alguns municípios da GERES I realizam menos partos do que o esperado, levando a transferências desnecessárias e a super-lotação das maternidades do Recife.

Abstract Objectives: this study aims to evaluate parturition distribution of live-born children within the First Health Regional Administration (GERES I) in the state of Pernambuco, Brazil in 2012. Methods: live Birth Certificates were used to evaluate displacements between pregnant women's residential municipalities and birth localities. Flux maps were constructed to represent pregnant women transferred to Recife, and the estimated number of live-borns with high-risk and regular births was calculated for each municipality. Results: in 2012, only 50% of the births of live babies in the GERES I took place at the original residential municipality of the mother. In Recife, the number of childbirths was 1.5 times greater than expected for this year, with 56% representing non-residents. Eleven municipalities of the GERES I have maternity hospitals, however, none of these responded to the expected number of regular risk births. Conclusions: this disruption of the obstetric network leads to the disrespecting of women's right to know beforehand the place of childbirth and to create bonds with it. Municipalities perform fewer childbirths than expected, resulting in unnecessary transfers and the overloading of maternity hospitals in Recife.

Objective: To standardize the single nucleotide polymorphism array (SNPa) method in acute myeloid leukemia/myelodysplastic syndromes, and to identify the similarities and differ- ences between the results of this method and karyotyping. Methods: Twenty-two patients diagnosed with acute myeloid leukemia and three with myelodysplastic syndromes were studied. The G-banding karyotyping and single nucleotide polymorphism array analysis (CytoScan(r) HD) were performed using cells from bone marrow, DNA extracted from mononuclear cells from bone marrow and buccal cells (BC). Results: The mean age of the patients studied was 54 years old, and the median age was 55 years (range: 28-93). Twelve (48%) were male and 13 (52%) female. Ten patients showed abnormal karyotypes (40.0%), 11 normal (44.0%) and four had no mitosis (16.0%). Regarding the results of bone marrow single nucleotide polymorphism array analysis: 17 were abnor- mal (68.0%) and eight were normal (32.0%). Comparing the two methods, karyotyping identified a total of 17 alterations (8 deletions/losses, 7 trissomies/gains, and 2 translocations) and single nucleotide polymorphism array analysis identified a total of 42 alterations (17 losses, 16 gains and 9 copy-neutral loss of heterozygosity). Conclusion: It is possible to standardize single nucleotide polymorphism array analysis in acute myeloid leukemia/myelodysplastic syndromes and compare the results with the abnormalities detected by karyotyping. Single nucleotide polymorphism array analysis increased the detection rate of abnormalities compared to karyotyping and also identified a new set of abnormalities that deserve further investigation in future studies.

OBJECTIVE: To assess, in a prospective way, the experience with video-assisted pericardioscopy obtained in patients with pericardial effusion of unclear etiology in the preoperative period. METHODS: From January 1998 to June 2000, 20 patients were operated upon with the aid of video-assisted pericardioscopy. On echocardiography, 17 of these patients had significant pericardial effusion, and 3 had moderate pericardial effusion. Video-assisted pericardioscopy was performed through a small incision of the Marfan type. RESULTS: The diagnosis of pericardial effusion was established as follows: idiopathic in 9 (45%) patients, neoplastic in 4 (20%), resulting from hypothyroidism in 3 (15%), tuberculous in 2 (10%), due to cholesterol in 1 (5%), and chylopericardial in 1 (5%). The biopsy was positive in 30% of the patients, and the etiology could not be defined in 45% of the patients. CONCLUSION: Video-assisted pericardioscopy proved to be a method with low morbidity and a high index of diagnostic positivity. A high percentage of pericardial effusions are caused by viral infections, which are not diagnosed through current methods, being, therefore, classified as idiopathic.
