ABSTRACT

Abstract Introduction Acromegaly is a chronic disease caused by growth hormone (GH) excess due to a GH-secreting pituitary adenoma in most cases. There is reasonable data to presume the possible influence of chronic GH and insulin-like growth factor I (IGF-I) hyperproduction on the anatomical structures involved in normal sound perception, and on its conductive and/or sensorineural part. Objectives To review the literature about acromegaly and hearing loss. Data Synthesis A systematic literature search was performed using the MEDLINE database, including hand-searching reference lists from original articles. The search was performed using the terms hearing loss and acromegaly, and only 5 studies were found. Conclusion The results are not consistent, but led to different conclusions. Therefore, more studies with greater numbers of patients with acromegaly are needed.

ABSTRACT

OBJETIVO: investigar a prevalência de níveis pressóricos elevados em pacientes com síndrome dos ovários policísticos (SOP) e correlacionar os níveis de pressão arterial (PA) com outros fatores de risco cardiovascular. MÉTODOS: por meio de estudo transversal, foram alocadas 113 mulheres com SOP (26,2±4,3 anos) e um Grupo Controle com 242 mulheres saudáveis da população geral (26,8±5,0 anos). As variáveis consideradas foram: PA sistólica e diastólica, parâmetros antropométricos e concentrações séricas de glicose, colesterol total, HDL-colesterol e triglicerídeos. Os valores de PA foram classificados de acordo com as V Diretrizes Brasileiras de Hipertensão. A análise estatística constou da comparação intergrupos com os testes t de Student e do χ2 e análise de correlação com teste de correlação de Pearson. RESULTADOS: o Grupo SOP apresentou prevalência de PA alterada (>130/85 mmHg) significativamente superior ao Grupo Controle (18,6 versus 9,9 por cento, respectivamente; p<0,05). Mulheres com SOP apresentaram valores médios superiores de PA sistólica, índice de massa corpórea (IMC), circunferência da cintura (CC), triglicerídeos e glicemia de jejum, além de níveis inferiores de HDL-colesterol, em comparação ao Grupo Controle (p<0,01). No Grupo SOP, os valores de PA sistólica e diastólica apresentaram correlação positiva significativa com a idade, IMC, CC e triglicerídeos (p<0,05). CONCLUSÕES: de acordo com os resultados obtidos, é possível concluir que a frequência de mulheres com valores acima do limite da normalidade das cargas pressóricas foi significativamente superior no Grupo SOP, em relação ao Grupo Controle. Adicionalmente, os valores de PA se correlacionaram com outros fatores de risco cardiovascular. Esses achados alertam para a relevância de estratégias preventivas em mulheres com SOP, no sentido de evitar eventos mórbidos relacionados ao sistema cardiovascular.


PURPOSE: to investigate the prevalence of elevated blood pressure (BP) in patients with polycystic ovary syndrome (PCOS) and to correlate the BP levels with other cardiovascular risk factors. METHODS: a cross-sectional study was conducted on 113 PCOS women (26.2±4.3 years) and on a Control Group of 242 healthy women from the general population (26.8±5.0 years). The variables considered were: systolic and diastolic BP, anthropometric parameters and plasma levels of glucose, total cholesterol, HDL-cholesterol, and triglycerides. The BP values were classified according to the V Brazilian Guidelines of Hypertension. Statistical analysis was performed by intergroup comparison with the Student's t-test and χ2 test, and correlation analysis was performed using Pearson's coefficient. RESULTS: the PCOS Group showed a significantly higher prevalence of altered BP (>130/85 mmHg) than the Control Group (18.6 versus 9.9 percent, respectively; p<0.05). PCOS women had higher mean systolic BP, body mass index (BMI), waist circumference (WC), triglycerides and fasting glucose, and lower HDL-cholesterol, compared to the Control Group (p<0.01). In the PCOS Group, the values of systolic and diastolic BP showed a significant positive correlation with age, BMI, WC, and triglycerides (p<0.05). CONCLUSIONS: according to the results obtained, it is possible to conclude that the frequency of women with BP values above the normal limit was significantly higher in the PCOS Group than in the Control Group. Additionally, the BP values also correlated with other cardiovascular risk factors. These findings underscore the importance of preventive strategies in PCOS women, in order to prevent pathological events related to the cardiovascular system.

ABSTRACT

OBJETIVO: avaliar o desempenho da biópsia helicoide na realização de biópsias mamárias. MÉTODOS: foi selecionado aleatoriamente uma amostra composta de 30 pacientes portadoras de câncer de mama submetidas à mastectomia. Foram excluídas as mulheres portadoras de tumor que tivessem consistência pétrea, não-palpável, com manipulação cirúrgica prévia ou que contivesse líquido. Utilizando-se o kit de biópsia helicoide e um equipamento de core biopsy com cânula e agulha de 14 gauge, respectivamente, coletou-se um fragmento por equipamento em área sã e nos tumores, em cada peça cirúrgica, totalizando 120 fragmentos para estudo histológico. Para a análise dos dados, definiu-se um nível de confiança de 95 por cento e utilizou-se o software SPSS, versão 13; o índice de concordância Kappa e o teste paramétrico t de Student. RESULTADOS: a média das idades das pacientes foi de 51,6 anos (±11,1 anos). A core biopsy apresentou sensibilidade de 93,3 por cento, especificidade de 100 por cento e acurácia de 96,7 por cento, enquanto a biópsia helicoide teve sensibilidade de 96,7 por cento, especificidade de 100 por cento e acurácia de 98,3 por cento. Na comparação entre a histologia dos tumores e dos fragmentos de biópsias, houve alto grau de concordância nos diagnósticos (Kappa igual a 0,9, com p<0,05). CONCLUSÕES: ambos os equipamentos proporcionaram o diagnóstico histológico das lesões com alta acurácia. Os resultados deste estudo demonstraram que a biópsia helicoide é uma alternativa confiável no diagnostico pré-operatório de lesões mamárias.


PURPOSE: to assess the helicoid biopsy performance when carrying out breast biopsies. METHODS: thirty patients with breast cancer submitted to mastectomy were selected at random. Women with a tumor of petreous consistency, nonpalpable, submitted to previous surgical manipulation or containing fluid were excluded. The helicoid biopsy kit and a core biopsy device with a cannula and a 14-gauge-needle, respectively, were used to collect a fragment each from a healthy area and from the tumor of each surgical specimen, for a total of 120 fragments for histological study. Data were analyzed statistically by the parametric Student's t-test and by the Kappa concordance index at the 95 percent confidence level, using the SPSS software, version 13. RESULTS: the mean patient's age was 51.6 (±11.1) years old. The core biopsy showed 93.3 percent sensitivity, 100 percent specificity and 96.7 percent accuracy, and the helicoid biopsy showed 96.7 percent sensitivity, 100 percent specificity, and 98.3 percent accuracy. The comparison of tumor histology and biopsy fragments revealed a high degree of concordance in the diagnoses (Kappa equal to 0.9, with p<0.05). CONCLUSIONS: both methods provided a highly accurate histological diagnosis of the lesions. The results of the present study demonstrate that the helicoid biopsy is a reliable alternative for the preoperative diagnosis of breast lesions.
