RESUMEN
OBJECTIVES: The current study aimed at identifying the role of seizure types and related clinical features in differentiation between neurometabolic disorders and other causes of seizure. MATERIALS & METHODS: The current cross sectional study was conducted at two referral children hospitals in Tehran, Iran, from 2011 to 2018. The study population included 120 patients presenting with seizure due to neurometabolic disorders and 120 cases due to other causes. The types of seizure and related clinical findings were assessed in both groups. RESULTS: There was a significant difference in the frequency of seizure types in the two groups. Tonic and myoclonic seizures as well as infantile spasm were observed more commonly in the patients with neurometabolic disorders, while atonic, partial and generalized tonic-clonic seizures were more common in the control group. In addition, frequency of refractory seizure, age at onset of seizure, and pattern of involvement in brain imaging were helpful for differentiation. CONCLUSION: The pattern of seizure and related findings varied in patients with metabolic disorders, and was helpful for diagnosis. Thus, these factors can contribute to early diagnosis and treatment.
RESUMEN
BACKGROUND: Osteoporosis (OP) is a common complication of inflammatory arthritis such as rheumatoid arthritis (RA). In this study we evaluated Osteoporosis and its related factors in RA patients. METHODS: This cross - sectional study was carried out from 2010 to 2011 on 121 women with RA aged 45-75 years. These patients were selected and divided in two groups according to their bone mineral densitometry (BMD) status, osteoporotic and non osteoporotic. The data about OP and potential related factors were recorded. T-test for quantitative and X(2) for qualitative variables were used for group comparison. RESULTS: The mean age of the patients was 55.7±10.1 and the duration of the disease was 10.1±9.2 years. Thirty nine (32.3%) of patients had T score≤-2.5 [28 (23.1%) in the lumbar spine and 20 (16.5%) in the femoral neck of regions]. The age and body mass index (BMI) were the most significant factors related to OP (p=0.00, p=0.01). Surgery induced menopause was conversely related to OP in neck of femur (p=0.04). OP in femur was related to overall fracture in patients (p=0.02) and also with seropositivity for RF (p=0.04) and body mass index (p=0.01). CONCLUSION: The prevalence of OP in our patients was higher than expected. Old age, menopause, low BMI and seropositivity were the main risk factors of osteoporosis.
