Meta Analysis Comparative Study
[Effects of corticosteroids on adults with tuberculous meningitis admitted to intensive care unit: a propensity score analysis].
The beneficial effect of corticosteroids has been well established, particularly in patients free of infection with the human immunodeficiency virus. In intensive care units, the high risks of infection to which patients are exposed specifically could offset the neurological benefit of corticosteroids. The purpose of the study was to assess the effects of corticosteroids in adult patients with tuberculous meningitis admitted to intensive care unit. ⋯ This study found no significant improvement in survival in adult patients with tuberculous meningitis admitted to intensive care who received dexamethasone. However, the confidence interval was in accordance with the 0.78 relative risk estimated by the meta-analysis Cochrane version 2008. There was no significant difference for nosocomial infections between the group Corticosteroids and the group No corticosteroids. A probable lack of statistical power may explain these results.

Review Comparative Study
[Genetic iron overloads and hepatic insulin-resistance iron overload syndrome: an update].
Hepcidin inhibits intestinal absorption of iron through internalisation of ferroportin. Its discovery helps to better understand the genetic iron overloads. The insulin resistance-hepatic iron overload (IR-HIO)--also coined as the dysmetabolic iron overload syndrome--is a common cause or iron overload. ⋯ Treatment of IR-HIO is focused on metabolic syndrome and phlebotomies are questionable because the overload is moderate and intestinal absorption of iron seems to be low. MRI (or other non invasive methods) is needed to truly assess iron overload because serum ferritin overestimates it in metabolic syndrome. Several points have to be elucidated: how HFE interferes with hepcidin in type 1 haemochromatosis; the causes of variability of iron overload; the benefits of populations screening; the advantage of phlebotomies in IR-HIO; the use of new oral iron chelators.

Comparative Study
[Orofacial manifestations of systemic sclerosis: a study of 30 consecutive patients].
The face is frequently involved in systemic sclerosis. The main stomatologic manifestations include limited mouth opening, xerostomia, skin atrophy, trigeminal neuralgia. The objective of this study was to describe oral and facial manifestations observed in scleroderma patients from our cohort. ⋯ Oral and facial manifestations are frequently observed in scleroderma patients. These manifestations lead to major functional discomfort, mainly due to decreased mouth opening that seems to be frequently associated to oesophageal involvement. Xerostomia is also frequent and is commonly observed in anticentromere antibodies positive cutaneous limited forms of systemic sclerosis. Evolution of radiographic abnormalities like periodontal ligament space widening (33% of cases), or osteolytic lesions (7%) is poorly known.
