Percutaneous closure of a large ductus arteriosus with the Amplatzer device

We describe here the first Lebanese experience of percutaneous closure of a large patent ductus arteriosus in a 15-year-old female. The ductus arteriosus was successfully occluded using the new Amplatzer Duct Occluder system. The procedure time was 40 minutes and the young patient was discharged home the next day. This new device, conceived since 1997, gives very encouraging results according to the recent medical literature.

Cryoglobulinemia in chronic hepatitis C virus infection. About 76 cases

Cryolobulines are immunoglobulins that persist in the serum, precipitate with cold temperature and resolubilize when rewarmed. There are 3 types of cryoglobulinemia. Type II and III define mixed cryoglobulinemia. 40% approximately of patients with chronic hepatitis C virus (HCV) infection had cryoglobulinemia. OBJECTIVE: To evaluate the frequency of cryoglobulinemia in a chronic hepatitis virus (CHV) infection group and determine the characteristics of positive cryoglobulinemia patients. RESULTS: 76 patients were included. There were 53 women an 23 men. The mean age was 59.45 years. Mixed cryoglobulinemia was detected in 65 patients (85.5 %). Cirrhosis, old age and the long duration of CHV infection were the 3 factors associated with cryoglobulinemia positivity. CONCLUSION: Mixed cryoglobulinemia is a frequent manifestation during chronic hepatitis C infection virsus especially in patients with cirrhosis.     

Genetic linkage of autosomal dominant progressive supranuclear palsy to 1q31.1

Progressive supranuclear palsy (PSP) is a disorder of unknown pathogenesis. Familial clusters of PSP have been reported related to mutations of protein tau. We report the linkage of a large Spanish family with typical autosomal dominant PSP to a new locus in chromosome 1. Four members of this family had typical PSP, confirmed by neuropathology in one case. At least five ancestors had similar disease. Other members of the family have incomplete phenotypes. The power of the linkage analysis was increased by detecting presymptomatic individuals with 18F-fluoro-dopa and 18F-deoxyglucose positron emission tomography. We screened the human genome with 340 polymorphic markers and we enriched the areas of interest with additional markers. The disease status was defined according to the clinical and positron emission tomography data. We excluded linkage to the tau gene in chromosome 17. PSP was linked, in this family, to one area of 3.4 cM in chromosome 1q31.1, with a maximal multipoint < OD score of +3.53. This area contains at least three genes, whose relevance in PSP is unknown. We expect to further define the gene responsible for PSP, which could help to understand the pathogenesis of this disease and to design effective treatment.     

Iron deficiency anemia and proteino-energetic status in woman from 15 to 49 years old in Tunisia

A foodstuffs survey has been carried out on young women aged from 15 to 49 in order to determine the total and available iron supplies, in proteins and in energy so as to establish the link between an iron deficiency and the protein-energy supplies in comparison to the needs required by the FAO and the WHO. The regions studied are the Great Tunis (GT) and the South West (SW) both in urban and rural backgrounds. These two regions have been selected because of the high prevailing rate of deficiency discovered after the 1996/1997 nutritional survey. Women have been divided into two groups: those who have a deficiency and those who don't have. The study concerned 1151 homes therefore about 1468 women and from them 712 are from GT and 756 from SW. The results of foodstuffs survey demonstrated that supply of meat is more elevated in non anemic women than anemic women concerning proteins supplies. A moderate energetic deficit is noticed in non deficient women and those anemic who have an iron deficiency. Women presented anemia have total and available iron deficient and a deficiency in energy supplies.     

Effect of school policy on tobacco use by school personnel in Bihar, India

This study examined the relationship between school tobacco policies and tobacco use prevalence among school personnel. Two subsets of schools were identified in Bihar, India: Federal Schools (with a tobacco policy), and State schools (without a tobacco policy). Stratified probability samples of 50 schools each were selected. The survey was conducted through an anonymous, self-administered questionnaire. School personnel from State Schools (non-policy schools) reported significantly higher daily cigarette smoking and daily current smokeless tobacco use compared to personnel in Federal schools (policy schools). Teachers in State schools did not teach about health consequences of tobacco, and they had not received training for such teaching. Extent of teaching about health consequences of tobacco varied across topics for teachers in Federal schools. They received negligible training, but more than 35% reported access to teaching materials. More than one-half the personnel from Federal schools knew about their school's policy prohibiting tobacco use among students and school personnel, and about policy enforcement. Personnel in State schools did not know about tobacco control policy in their schools. All school personnel in both types of schools were near unanimous in supporting policy prohibiting tobacco use in schools. The study demonstrated an association between enacting a school policy regarding tobacco use and school personnel's use of tobacco, curricular teaching, and practical training of students. Findings suggest that more extensive introduction of comprehensive school policies may help reduce tobacco use among school personnel.
