The role of platelet parameters in thrombosed hemorrhoids / O papel dos parâmetros plaquetários nas hemorróidas trombosadas

ABSTRACT Objectives: The most common disease of anus is hemorrhoids. The definition of external hemorrhoids suggests the acute phase, often characterized by thrombosis or edema. External thrombosed hemorrhoid is a specific complication. In this study, we aimed to investigate the effects of different platelet parameters in the presence of internal or external thrombosed hemorrhoids. Methods: Patients examined were divided into two groups: Group 1: Thrombosed hemorrhoids group (THG), Group 2: Hemorrhoidectomy group (HG). Demographic and clinical data were identified. In terms of laboratory findings, preoperative hemoglobin, hematocrit and all platelet parameters were recorded. Main results: Fifty-two patients in THG, and 75 patients in HG were included in the study. In female sex and young age group, the risk of developing thrombosed hemorrhoids was statistically significant (p= 0.029, p= 0.039, respectively). When the platelet parameters were evaluated; while PDW was higher in THG (p= 0.008), any significant difference could not found in all other values (p> 0.05). Thrombosed hemorrhoids were mostly (59.25%) found to be located in the left laterodorsal part of anus. Conclusion: Internal hemorrhoids are frequently seen in the ages of 45-65 with similar rates in both sexes, while external thrombosed hemorrhoids occur at a younger age (<45) and more often in women. Comparing in terms of platelet indexes, PDW value was found to be significantly higher in THG. In young people, thrombosed hemorrhoids may develop more frequently, as the connective tissue that forms the anal pads is not loose enough to form an internal hemorrhoid, as more seen in older patients.

RESUMO Objetivos: A doença anal mais comum são as hemorróidas. A definição de hemorróidas externas sugere a fase aguda, muitas vezes caracterizada por trombose ou edema. A hemorroida externa trombosada é uma complicação específica. Neste estudo, objetivamos investigar os efeitos de diferentes parâmetros plaquetários na presença de hemorróidas trombosadas internas ou externas. Métodos: Os pacientes examinados foram divididos em dois grupos: Grupo 1, Grupo de Hemorróidas Trombosadas (GHT); Grupo 2, Grupo de hemorroidectomia (GH). Os dados demográficos e clínicos foram identificados. Em termos de achados laboratoriais, a hemoglobina pré-operatória, o hematócrito e todos os parâmetros plaquetários foram registrados. Resultados principais: Cinquenta e dois pacientes em GHT e 75 pacientes em GH foram incluídos no estudo. No sexo feminino e na faixa etária jovem, o risco de desenvolver hemorróidas trombosadas foi estatisticamente significativo (p = 0,029, p = 0,039, respectivamente). Os parâmetros plaquetários avaliados mostraram que, enquanto a Amplitude de Distribuição de Plaquetas (PDW, do inglês platelet distribution width) foi maior no GHT (p = 0,008), nenhuma diferença significativa foi encontrada para todos os outros valores (p > 0,05). A maioria das hemorróidas trombosadas (59,25%) localizava-se na região lateral-dorsal esquerda do ânus. Conclusão: As hemorróidas internas são frequentemente vistas nas idades de 45 a 65 anos com taxas semelhantes em ambos os sexos, enquanto as hemorróidas externas trombosadas ocorrem em uma idade mais jovem (<45) e mais frequentemente em mulheres. Comparando em termos de índices de plaquetas, foi observado que o valor de PDW foi significativamente maior no GHT. Em pessoas jovens, as hemorróidas trombosadas podem se desenvolver com mais frequência, pois o tecido conjuntivo que forma as almofadas anais não é flácido o suficiente para formar uma hemorroida interna, como ocorre com mais frequência em pacientes mais velhos.

Cigarette smoking habits among men and women in Turkey: a meta regression analysis

Smoking has become more prevalent in Turkey than it has in those of western countries during the past decade. This study was conducted to make parameter estimations on gender related smoking habits with the minimum of variance. Of the ninety-two researches related to smoking habits conducted from 1981 to 2003 in Turkey, 60 were deemed appropriate for the application of Meta analysis and Meta regression analysis. The proportions of men and women smoking cigarettes were 0.51 and 0.35, respectively. The proportion of men smoking cigarette in 1996 and the years before it was 0.52, and for women as 0.35. However, the figures for the years following 1996 were 0.41 for men, and 0.32 for women. In the results of the Dersimonian and Laird random effect model, the Odds Ratio, which shows the tendency of men to smoke compared to women, was found 1.894 for the period of 1981-2003. A heterogeneous distribution between the researches was apparent [Q=1560.91, P<0.001] as well as for Tau-square test [x2=0.55, z=6.29, P<0.001]. We propose that effective precautions should be considered, especially with regard to the introduction of laws to minimize the smoking habit for both sexes, with particular attention to women
