Pituitary-thyroid function in patients with septic shock and its relation with outcome.

Objective: To study the time course of thyroid function abnormalities and their relation to outcome in patients with septic shock.

Design: Prospective study in a cohort of consecutive patients.

Setting: Intensive Care Unit in a University Hospital.

Low levels of basic fibroblast growth factor (bFGF) are associated with a poor prognosis in human breast carcinoma.

It has been suggested that angiogenesis and angiogenic factors may be strong predictors of relapse in patients with breast carcinoma. We measured the levels of the angiogenic peptide basic fibroblast growth factor (bFGF) in 140 breast tumour cytosols using an immunoassay. There were no significant differences in bFGF levels between breast non-malignant lesions and primary carcinomas.

Diagnostic value of three tumor markers determined in pleural effusions.

In order to discriminate between malignant and benign effusions, the values of tissue polypeptide specific antigen,carcinoembryonic antigen and squamous cell carcinoma associated antigen were measured in the pleural fluid of 30 patients with neoplasm, 10 with tuberculous pleurisy, 10 with transudates due to congestive heart failure or cirrhosis, 29 with parapneumonic effusions and 23 with benign diseases other than tuberculosis and pneumonia. Carcinoembryonic antigen and tissue poly-peptide specific antigen levels in effusions due to neoplasms were significantly higher than those in effusions due to other diseases. The areas under Receiver Operating Characteristic curves for carcinoembryonic antigen and tissue polypeptide specific antigen determinations were 0.

Calcitonin and bisphosphonates treatment in bone loss after liver transplantation.

Osteopenia is a major complication of orthotopic liver transplantation (OLT). However, no effective therapy for bone disease has been defined. We have studied vertebral bone mineral density (VMD) and fasting serum markers of bone formation [bone gla protein (BGP), procollagen I carboxyterminal peptide (PICP)] and metabolism (serum Ca, P, intact parathyroid hormone (iPTH), 25OHD3 and 1,25(OH)2D3) in 120 patents after OLT.

Correlations between bone mineral density, insulin-like growth factor I and auxological variables.

Recent studies have shown growth-related changes in spinal bone mineral density (BMD) in children; however, there is less information available on the relationship between BMD and insulin-like growth factor I (IGF-I). The aim of this study was to relate the BMD of the spine and radius with serum IGF-I levels and auxological variables in normally growing children. We used dual X-ray absorptiometry to measure the BMD in the lumbar spine (L1-L4) and distal radius of 121 children (69 boys, 52 girls) aged 3-18 years whose growth velocity was normal.
