ABSTRACT
Statement of Problem: Carpal tunnel syndrome [CTS] is an important cause of work disability. There is controversy over the relation between carpal tunnel syndrome and occupation. The aim of this study was to assess the relationship between the time-span of practicing dentistry and the role of dominant hands in the development of carpal tunnel syndrome
Materials and Method: In this descriptive cross sectional study, 40 dentists and dental students [15 women and 25 men] undertook the electroneuro-diagnostic test in both hands by an electromyogram [EMG] and they were also evaluated in terms of self- reported clinical symptoms
Results: 17.5% of participants were diagnosed to have decreased nerve conduction velocity while10% had reported clinical symptoms of CTS. Both dominant and nondominant hands were involved. Within cases who were diagnosed as having median nerve neuropathy, 87.5% worked more than 20 hours per week. 57% had 17-23 years of dental practice experience and 14.2% of cases had10-16 years of practice in dentistry
Conclusion: The high rate of CTS symptoms, in both dominant and non-dominant hand among dental practitioners with more years of dental practice, indicates a prequisite for particular attention, then sufficient education on the major risk factors causing this problem. Early diagnosis of these symptoms may improve the future management of the disease
ABSTRACT
Hyperhomocysteinemia is a rare autosomal recessive inherited metabolic disorder. The main clinical manifestations of hyperhomocysteinemia include mental retardation, psychological disturbance, thromboembolic events and skeletal abnormalities. The case reported here is of a 28 year-old man admitted in hospital with recurrent seizures. In the brain MRI, areas of venous infarction were seen and MRA revealed thrombosis in brain venous sinuses. Lab investigation showed increases in serum level of homocystein and protein C deficiency. The patient had no family history of genetic disease or cerebrovascular attack. As sinus thrombosis is a multifactorial disease, Protein C deficiency can be one of aggravating causes of thromboembolic events in patients with hyperhomocysteinemia
