Bone biopsy results and serum bone turnover parameters in uremic children.

Unlabelled: The aim of the study was to evaluate the prevalence of renal osteodystrophy types in children undergoing haemodialysis and continuous ambulatory peritoneal dialysis and to assess the usefulness of biochemical parameters in diagnosis of renal osteodystrophy. Bone biopsy and measurements of serum parathormone (iPTH) level, alkaline phosphatase (AP), osteocalcin (OC), procollagen 1C, calcium and phosphorus levels were performed in 51 children aged 11.5 +/- 2.

[Pericarditis during the course of pulmonary embolism].

Among 121 patients with pulmonary embolism (PE) five (4%) developed pericardial syndrome, connected with PE. Other known causes of pericarditis were ruled out. In 3 cases corticosteroids were administered with anticoagulants and/or fibrinolytic agents without complications.

[Evaluation of agreement between clinical and pathomorphologic diagnosis of pulmonary embolism].

The rate of both: false-positive and false-negative diagnoses of pulmonary embolism (PE) is high. To determine the accuracy of the ante-mortem diagnosis of PE we reviewed 78 autopsies and compared the clinical and pathological diagnoses in that group. In 64 cases PE was diagnosed clinically: in 43 it was confirmed by autopsy (67%).

[Effect of large doses of nifedipine on pulmonary hypertension in patients with recurrent pulmonary thromboembolism].

Thromboembolic pulmonary hypertension is an uncommon condition with poor prognosis. Vasodilators may be effective in some patients with that disease. The effect of nifedipine on hemodynamics was investigated in two patients with thromboembolic pulmonary hypertension treated with acenocoumarol.

The prognostic significance of bone marrow metastases in small cell lung cancer patients.

One-hundred forty-six SCLC patients were classified as localised (56) or extensive (90) using chest X-ray, bronchoscopy, brain CT, bone scintigraphy, ultrasonography of the abdomen and bilateral bone marrow trephine biopsy. Bone marrow metastases were found in 28 cases. Patients with bone marrow metastases had significantly shorter time to progression (median 20 weeks) and significantly shorter survival time (median 31 weeks) than other patients with extensive disease (medians 30 and 46 weeks).
