Abstract
Proximal weakness specially in extremitas is a common neurologic symptom of patients, for which the physician should consider toxic, metabolic, infectious and paraneoblastic diseases affecting muscular system as well as primary myopathies. Osteomalacia is one of the most common considerations which is treatable but disabling as its natural course. Osteomalacia is the most often due to VITD or calcium deficiency but work up is necessary to find other primary defects that cause this disease. Renal tubular acidosis is one of these primary defects and osteomalacia secondary to it dose not respond to classic treatment of osteomalacia, so specific management is necessary. In this article we report six patients who have been referred to the clinic of neurology of Imam Khomeini Hospital since 1370 to 1374 with proximal weakness for whom RTA has been diagnosed

Abstract
In a cross-sectional epidemiological study of headache disorders in neurology clinic of Fatemieh hospital of Semnan (August 22-November 20.1996), information on types of headaches, quality, severity, location, duration, frequency, precipitating factors, age of onset, influence of menstruation and pregnancy, positive familial history, use of oral contraceptive pills and other epidemiological factors including socioeconomic and age/sex composition was collected. The presence of any types of headaches was ascertained by a clinical interview and examination using the operational diagnostic criteria of the International Headaches Society. The prevalence of migraine and tension type headache was also analysed in relation to variables of life style (physical activity and sleep pattern) and associated signs and symptoms (nausea, vomiting, photophobia and phonophobia). In this study migraine and tension headache were also compared in variable aspects with each other. 1) Headache was more prevalent in women than men (F/M=3/1). 2) The most common types of headache included: tension type headache (41.4%), migraine (31.2%) and unclassified headaches (17.2%). 3) Migraine and T.T.H were more prevalent in early adult life and middle ages. 4) In both migraine and tension type headache the time profiles (duration, frequency, age of onset), quality and location were like that noted in textbook and previous studies. 5) In both migraine and tension type headache the most conspicuous precipitating factor was stress and mental tension and frequent headaches were accompanied with psychiatric problems (e.g depression and or anxiety). 6) Nausea, vomiting, phonophobia and photophobia were the most common associated symptoms in both of them. 7) Positive familial history and aggravation of headache in perimenstual period were more commonly seen in patients with migraine than tension type headache. In conclusion using the operational diagnostic criteria of International Headache Society in clinical practice, treating, teaching, clinical and epidemiological research is very useful and must also be applied for Iranian patients.

Abstract
This is a prospective descriptive research which was carried out in Imam Khomeini Hospital related to Tehran University during two years (1375-1377) in order to study the incidence of internal carotid stenosis in patients who suffered from TIA ot minor stroke. It was evaluated by duplex sonography. Risk factors of carotid stenosis were studied. 1052 patients who had cerebrovascular accident admitted to Imam Khomeini Hospital and 100 of them who suffered from TIA or minor stroke were selected. The data was gathered by questionnaire and analysed. According to the results of the research, the incidence of internal carotid stenosis was 81%. The incidence of severe stenosis (>70%) was 20%, moderate stenosis (30-69%) was 36%, and mild stenosis (<29%) was 44%. There was a significant relationship between hyperlipidemia, diabetes mellitus and alcohol consumption, with internal carotid stenosis. There was no significant relationship between hypertension and cigarette smoking with internal carotid stenosis. There was a significant relationship between history of angina pectoris or myocardial infarection with severity of internal carotid stenosis. We suggest to consider duplex sonography as a part of evaluation of patients who suffer from TIA or minor stroke for screening of severe internal carotid stenosis. Control and treatment of risk factors are useful preventive measures that can reduce the incidence of carotid artery stenosis and cerebrovascular accidents

Abstract
Background: Myasthenia Gravis (MG) is a neuromuscular disorder with weakness of skeletal muscles. Thymectomy is now recognized as a treatment modality in MG. The aim of this study was to evaluate the clinical effect of thymectomy on MG.
Methods: MG patients with history of thymectomy at a tertiary referral center during twelve year period were included. The medical records were reviewed and telephone survey was conducted to evaluate the effects of thymectomy.
Results: Sixty MG patients, 46 females and 14 males, aged 30.4±11.1 years, underwent open (n=48) or video-assisted thoracoscopic thymectomy (n=12) during study period. The mean dosage of preoperative pyridostigmine was 235.4±86.2mg/day. This figure reached to 129±18mg/day after thymectomy (p<0.0001). 17 patients (28.3%) had complete remission (complete freedom of symptoms without medications). Improve-ment (improved symptoms or less medication requirement) was seen in 34 patients (56.6%). There was no response to surgical therapy in six patients (10%). Three patients (5%) had experienced progression of disease postoperatively. Overall, benefit of thymectomy was observed in 85% of patients. Age, sex, duration and severity of disease, quantity of preoperative drugs, surgical approach, and presence of thymoma did not affect the outcome. Satisfaction was stated as excellent in 17%, good in 43%, moderate in 35% and poor in 5% of patients after operation.
Conclusion: Thymectomy is an effective treatment for MG which leads to less severity of disease and less drug requirement. It would be considered in all myasthenic patients regardless of age, sex, duration and severity of disease and presence of thymoma.

Abstract
Background: Visual, brain stem auditory and somatosensory evoked potentials (EPs) have been traditional paraclinical tests to evaluate the competency of sensory tracts in multiple sclerosis (MS) patients. It seems that only one of these EPs could be sufficient, at least as a screening test. The objective of this paper is to evaluate the frequency of these three evoked potentials in definite MS patients.
Methods: This descriptive cross-sectional study involved was 25 definite relapsing remitting MS patients who referred to our university hospital. Twenty five individuals from normal population without any neurologic, visual, auditory or sensory disorders have been evaluated as well to determine the standard values in our electrophysiology lab. Values more than mean+2.5SD for latencies and less than mean-2.5SD for amplitudes were considered as abnormal.
Results: Fifteen (60%), 13 (52%), and 13 (52%) had abnormal visual, auditory and somatosensory EPs respectively. The latency of P100 in visual EP (VEP) had the most sensitivity among all of the parameters. It was determined that the possibility of abnormality in each of auditory and somatosensory EPs in the presence of normal VEP could be 30.8%. In other words 30.8% of patients with negative VEP could have a positive auditory brain stem or somatosensory EPs.
Conclusion: In our study, a VEP abnormality was more frequent than auditory brain stem and somatosensory EPs. Thus it is not logical to perform triple EP tests in all suspected MS patients, but auditory and somatosensory EPs could be considered in patients with normal VEP.
