Association of rheumatoid arthritis-related autoantibodies with pulmonary function test abnormalities in a rheumatoid arthritis registry.

Introduction: We investigated whether rheumatoid arthritis (RA)-related autoantibodies were associated with abnormalities on pulmonary function tests (PFTs).

Methods: We studied RA serostatus and PFT abnormalities within a RA registry. RA serostatus was assessed by research assays for cyclic citrullinated peptide (CCP) and rheumatoid factor (RF).

Increased whole blood manganese concentrations observed in children with iron deficiency anaemia.

A prospective observational study was carried out at Alder Hey Children's Hospital, Liverpool, England, UK on children aged 1-6 years attending the pathology department for routine blood tests (n=225). Whole blood manganese concentrations were measured plus the following markers of iron status; haemoglobin, MCV, MCH, RBC count, ferritin, transferrin saturation and soluble transferrin receptors. Multiple regression analysis was performed, with blood manganese as the dependent variable and factors of iron status, age and gender as independent variables.

Aluminum accumulation in critically ill children on sucralfate therapy.

BACKGROUND: Sucralfate, used in stress ulcer prophylaxis, contains aluminum, which can be absorbed from the gut. OBJECTIVE: To determine whether toxic serum aluminum levels can develop after short-term sucralfate therapy in critically ill children. DESIGN: Retrospective clinical study.
