MRI but not demographic or clinical characteristics differ between familial and sporadic MS cases.

BACKGROUND: Multiple sclerosis (MS) is a chronic immune-mediated demyelinating disease. The prevalence and incidence of MS in Iran is high and is rising over time. This study was conducted to compare the demographic, clinical features and MRI findings of MS patients with history of the disease in the first-degree family members (fMS) with sporadic MS patients (sMS) to determine the importance of genetic or non-genetic factors in the development of the disease and its effect in diagnostic and therapeutic modalities. METHODS: Among the 185 patients admitted to the study, 62 were fMS patients and 123 were sMS patients. All patients underwent clinical examination and data was gathered on age, sex, age of onset, symptoms, number of attacks, disease course, family history, disease-modifying drugs, and other accompanying diseases as well as MRI findings and EDSS scores. RESULTS: In this study, we demonstrated that the frequency of plaques in the periventricular area was significantly higher in sMS patients (97.56% vs 88.71%, p = 0.01) while the callosal plaques were more common in fMS patients (62.9% vs 47.97%, p = 0.05) which was statistically borderline and nonsignificant. In other evaluated parameters, no significant difference was observed. CONCLUSION: In our study, no significant difference was observed between the demographic and clinical characteristics of fMS and sMS patients, while there was a significant difference between the two groups in MRI findings.

A Single Center Study Comparing the Stainable Iron Depositions in 1000 Explanted Cirrhotic Livers of Different Causes.

BACKGROUND: There have been very few studies evaluating the close association between excess iron and cirrhosis; however, cirrhosis could be regarded as an iron-loading disorder. OBJECTIVES: In this study, the goal was to show the levels of the iron content in the liver tissue in certain types of cirrhosis. PATIENTS AND METHODS: In this 7 year study (2008 - 2014), in 1000 explanted livers, the amount of iron was scored and compared according to the cause of the cirrhosis. The amount of iron in the liver was determined via the histochemical staining of the liver tissue, using Prussian-blue staining. Additionally, in each patient, the serum iron was determined and compared according to the cause of cirrhosis. RESULTS: The highest content of iron has been found in cirrhosis caused by chronic hepatitis (i.e. hepatitis B, C, and autoimmune hepatitis), as well as in alcoholic cirrhosis. The least amount of stainable iron has been shown in biliary cirrhosis. CONCLUSIONS: The presence of high stainable iron in patients with cirrhosis, secondary to chronic viral hepatitis, autoimmune hepatitis, and alcoholic hepatitis, should not be considered indicative of the presence of hereditary hemochromatosis; however, in those patients with biliary cirrhosis, a high iron content is rare, and can be a sign of the presence of the high iron Fe (HFE) gene mutation, or another type of hereditary hemochromatosis.
