The frequency of menorrhagia and bleeding disorders in university students.

STUDY OBJECTIVE: Menorrhagia is an important health problem in women of reproductive age. The aims of this study were to assess the prevalence of menorrhagia and hemostatic abnormalities associated with menorrhagia in university students. METHODS: The pictorial blood assessment chart (PBAC) was used to identify students with menorrhagia. Those with a PBAC score > 100 were examined by pelvic ultrasound and laboratory tests including complete blood count, levels of clotting factors, von Willebrand factor antigen, and ristocetin cofactor activity and Platelet Function Analyser-100 (PFA-100). Platelet aggregation was studied in students with prolonged PFA-100 closure time. RESULTS: Menorrhagia was identified in 82 (21.8%) of 376 students. Six of 82 students who had pelvic pathologies were excluded. Eleven (14.5%) of the remaining 76 students were found to have bleeding disorders, including von Willebrand disease in five (6.5%), platelet function disorder in four (5.2%), and clotting factor deficiencies in two (2.6%). CONCLUSIONS: Menorrhagia is a common but mostly unrecognized and untreated problem among university students. Underlying bleeding disorders are not rare and require comprehensive hemostatic evaluation for identification.

The risk factors for thrombosis in children with acute lymphoblastic leukemia.

We aimed to scrutinize the risk factors for thrombosis in children with acute lymphoblastic leukemia treated with the Berlin-Frankfurt-Münster 95 protocol. The study population was 82 children younger than 16 years of age. The children were followed up for 10 years until January 2007. Thrombosis occurred in 10 (12%) of 82 patients during the treatment course, mainly after the M protocol. The most common risk factor was factor V Leiden (FVL; 15.6%). This was followed by methyleneterahydrofolate reductase (MTHFR; 9.3%), elevated lipoprotein (1.5%), and prothrombin (PT) 20210A (1.5%) in descending order. The risk of thrombosis was found to be significantly high in patients with FVL mutation (odds ratio = 7.1, 95% confidence interval = 1.6-30.5). The risk of thrombosis was not significant in patients with MTHFR and PT20210A mutation (P = .2). Age, catheter usage, FVL mutation, and prednisolone treatment are significant risk factors for thromboemboli occurrence.
