ABSTRACT
Background: There is supportive evidence that multiple sclerosis (MS) could potentially affect the peripheral nervous system. We assessed peripheral sensory and motor nerve involvement in patients with MS by a nerve conduction velocity test. Methods: We studied 75 patients who had a relapsing-remitting or secondary progressive pattern. We measured amplitude, latency, conduction velocity, Hoffmann reflex (H-Reflex), and F-Waves. Results: The amplitude of the right tibial, right proneal, left tibial, left proneal, and left median motor nerves was less than the mean for the normal population. Right ulnar sensory conduction in the patients showed an amplitude that was less than that of the normal population; there was no significant change in the amplitude of other sensory nerves. Latencies of the right and left median and right proneal motor nerves and left ulnar sensory nerves were statistically less than that of the normal population. Mean motor conduction velocity and F-wave conduction did not differ significantly from the normal population. H-reflex latencies of the right and left lower limbs were significantly more prolonged than those of the normal population. Conclusion: Our results suggest possible peripheral motor nerve abnormalities in MS patients, especially with the amplitude of the motor nerves; however, our results do not demonstrate any significant difference among the nerve conduction velocity parameters of sensory nerves between MS patients and the normal population.

Several reports concern the relationship between low dose oral contraceptive pills [OCP] and the occurrence of strokes. The present study investigates this relationship in childbearing stroke women admitted to university referral hospitals in North-West Iran. One hundred seventy eight female patients between 15 and 44 years of age who were admitted to two referral University Hospitals in a six years period were evaluated in this descriptive-analytical study. Data concerning the use of OCP and other risk factors were recorded. The OCP usage data were compared between the patients and the matched normal population. The average age of the patients was 35.5 +/- 7.4 years. Seventy three patients were admitted with arterial stroke, 15 patients had cardioembolic origin, 39 patients with venous stroke and 46 patients with hemorrhagic stroke, 45.2%, 20%, 59% and 30.4% of them used OCP respectively. Approximately 26.3% of the matched female population of childbearing age used OCP and there was a significant correlation between venous stroke [P < 0.0001] and atherothrombotic stroke [P < 0.0001] with OCP usage. Migraine was the only risk factor that significantly correlated with OCP consumption and stroke. In addition, the data concerning OCP use in the stroke patients, without any other risk factors [32/71: 45%], demonstrated a significant difference comparing the matched population [P < 0.0001]. OCP usage increases the risk of venous and atherothrombotic stroke in North-West of Iran, particularly in those individuals who suffer concurrent migraine
ABSTRACT
Background and Objective: Multiple sclerosis (MS) is variable in its prevalence and manifestations in different regions of the world. Iran is one of the most populous countries in Middle East, it is important to have a better understanding of the epidemiology and clinical pattern of MS in different parts of Iran. Although Iran is said to be located in the low-risk area, recent studies have shown that the prevalence of MS in Iran may be much higher than what was previously thought. This study determines the current prevalence and clinical features of MS in East Azerbaijan province, North West Iran. Methods: All patients for this study were MS cases listed in the Committee for Diagnosis and Treatment of MS (CDTMS) registry. The study patients were all residents of East Azerbaijan Province who were diagnosed with MS by neurologists. Results: Out of one thousand cases, 269 were males (26.9%) and 731 females (73.1%).The female/male ratio was 2.7. The crude prevalence of MS in East Azerbaijan was 27.7/100,000 population. The mean age (SD) of patients was 33.4 (8.9) years. The relapse-remitting form of disease was seen in 67.7% of patients; primary-progressive disease in 2.8%; and secondary progressive disease in 11.2%. Conclusion: Our study suggests that MS prevalence in North West Iran lies in the medium frequency range.
ABSTRACT
The syndrome of hemiparkinsonism-hemiatrophy is an uncommon form of secondary Parkinsonism that presents with unilateral body Parkinsonism plus variable atrophy on the same side. Diagnosis of this syndrome needs a complete past medical history taking, as well as assessment of the familial history, clinical examination and complete paraclinical tests. The response to medical therapy has been variable in various researches. This case showed a good response to the addition of a dopamine agonist to levodopa therapy
