Lipid patterns and fibrinogen levels of smokers and non-smokers

Hypercholesterolaemia, smoking and elevated levels of fibrinogen are independent risk factors for cardiovascular disease (CVD). The aim of this study was to determine whether smoking indirectly affects the other risk factors, namely cholesterol and fibrinogen levels. Serum lipid patterns and fibrinogen levels were determined in 67 cigarette or beedi smokers and 51 non-smokers in the age group 18 to 50 years. Serum thiocyanate levels were measured as an indirect indicator or smoking exposure. Smokers had significantly higher serum thiocyanate levels than non-smokers. The serum total cholesterol levels in smokers was significantly higher than in non-smokers, but there was no association with the degree of smoking. In contrast, smokers had significantly elevated fibrinogen levels which were positively related to thiocyanate levels, indicating that plasma fibrinogen levels increase in smoking exposure. These results suggest that smoking may increase the risk of CVD by elevating plasma fibrinogen levels.     

A correlative study of the functional class and hemodynamic status following intracardiac repair of tetralogy of Fallot.

An attempt was made to correlate the NYHA Functional class with the hemodynamic status of 196 patients at an average of 21.2 months following the intracardiac repair of tetralogy of Fallot. 171 patients were in Functional class I (87.2%), 9 in class III (4.5%), 5 in class II (2.5%) and 11 in class IV (5.6%). Right and left heart catheterisation and cardiac angiography revealed the hemodynamic status of these patients to be excellent in 92 (46.4%), good in 37 (18.8%), satisfactory in 6 (3.0%) and unsatisfactory in 61 (31.6%). Whereas all patients in Functional class II, III and IV had unsatisfactory hemodynamic findings, patients in Functional Class I were hemodynamically heterogeneous and included excellent (53.8%), good (21.6%), satisfactory (3.5%) and unsatisfactory (21%) groups. The surgical technique did not seem to determine the functional status. While early reoperation is advisable for patients with functional disability, caution is necessary in considering reoperation for patients in Functional class I who have hemodynamic findings which are classified as unsatisfactory.     

Primary papillary carcinoma of the thyroglossal duct cyst--a case report

Thyroglossal duct cyst is the most common developmental anomaly of the thyroid gland, presenting as a mid line neck swelling. Malignancy arising in them is a rare event, with papillary thyroid carcinoma being the commonest. Thyroglossal duct cyst carcinomas are usually asymptomatic and are not suspected preoperatively in most instances, hence the need for surgical excision and careful pathological examination of these cysts. We present a case of a 57 year old lady who underwent a Sistrunk procedure for the removal of thyroglossal duct cyst, which was responsible for a progressive mid line neck swelling of 2 months duration. The thyroid gland was normal. Histological examination of the excised cyst showed a papillary thyroid carcinoma arising in the thyroglossal duct cyst. Long term survival of patients with thyroglossal duct cyst carcinoma is excellent.     

循证病例报告 原发性脑出血患者是否应该进行抗血小板或抗凝治疗？

原发性脑出血伴有血栓危险因素的患者治疗比较棘手，如以下病例：老年男性，55岁，因右侧肢体无力入院。既往患有难治陛高血压、Ⅱ型糖尿病、心绞痛及高脂血症。约10年前右侧肢体曾有一次轻微卒中。入院时所服药物为：阿司匹林75mg，1次／日；阿托伐他汀10mg，1次／日；苄氟噻嗪2．5mg，1次／日；雷米普利2．5mg，1次／日；氨氯地平5mg，1次／日；     

Unusual intraosseous transmigration of impacted tooth

Transmigration of an impacted tooth through the symphyseal suture is a rare and special developmental anomaly of unknown etiology that is unique to the mandibular canine. Maxillary canine transmigration is even rarer. Transmigrated canines are particularly significant due to the aesthetic and functional importance. A maxillary lateral incisor crossing the mid-palatal suture has never been reported in the literature. The aim of this report is to present the first case of simultaneous transmigration of a lateral incisor and canine in the maxilla. The paper also reports four unusual cases of unilateral canine transmigration in the maxilla and mandible and successful eruption of one of the transmigrated mandibular canines following orthodontic traction. Etiology of transmigration and its clinical considerations are also discussed.     

A case report of children of the same family presenting with congenital cataract- as part of a rare genetic disorder—Sengers Syndrome

Sengers syndrome is a rare autosomal recessive mitochondrial disorder characterized by congenital cataract, hypertrophic cardiomyopathy, and mitochondrial myopathy. We report two siblings with known mutation for Sengers Syndrome (AGK gene mutation) who presented to us with cataract and hypertrophic cardiomyopathy. They have a deceased elder sibling who was operated for cataract earlier.
