Sexual, addiction and mental health care needs among men who have sex with men practicing chemsex - a cross-sectional study in the Netherlands.

Drug use during sex ('chemsex') has been associated with sexually transmitted infections (STIs) and mental health harms. Little quantitative evidence exists on the health care needs of MSM practicing chemsex from a patient perspective. This study assessed self-perceived benefits and harms and the needs for professional counselling among MSM practicing chemsex.

Ultrasound-guided percutaneous ethanol ablation of parathyroid hyperplasia: preliminary experience in patients on chronic dialysis.

Objective: We report on a 3-year experience using single-shot, ultrasonography-guided, percutaneous ethanol ablation (PEA) of hyperplastic parathyroid glands in chronic dialysis patients suffering from secondary or tertiary hyperparathyroidism.

Materials And Methods: Seventeen uraemic patients (mean age 52 +/- 14 years) with hypercalcaemia and elevated serum levels of parathyroid hormone were assessed for ethanol ablation. Ten patients did not fulfil the inclusion criteria and underwent surgical parathyroidectomy.

3D versus 2D ultrasound: accuracy of volume measurement in human cadaver kidneys.

Rationale And Objectives: Comparison of the accuracy of 3D and 2D ultrasound in assessing the volume of human cadaver kidneys.

Materials And Methods: Before autopsy the volume of 22 kidneys was assessed from a 3D data set after manually tracing organ contours (3D volumetry) and by applying a 3D ellipsoid formula both on a 3D data set and 2D images. Measurements by water-displacement served as the gold standard.

Intraluminal 192Ir brachytherapy following transjugular intrahepatic portosystemic shunt revision: long-term results and radiotherapy parameters.

Purpose: The stenosis or occlusion of transjugular intrahepatic portosystemic shunt (TIPS) occurs in up to 75% of patients within 12 months after treatment. The aim of our investigation was to evaluate the feasibility, safety and efficacy of intraluminal high-dose rate brachytherapy (HDRBT) with Iridium-192 following TIPS revision to prevent restenosis due to pseudointimal hyperplasia.

Materials And Methods: Between September and November 1996, intraluminal BT was performed in five patients after TIPS revision.
