Minimally Invasive Approach to Esophageal Perforation after Endoscopic Ultrasound-Guided Fine-Needle Aspiration: A Report of 2 Cases.

Esophageal perforation after endoscopic ultrasound-guided fine-needle aspiration for mediastinal staging is a rare but severe complication. We report 2 cases of patients with esophageal perforation who were treated using video-assisted thoracoscopic surgery in combination with esophageal stenting. Through these cases, the feasibility of minimally invasive thoracic surgery was evaluated.

Knowledge gaps in patients with COPD and their proxies.

Background: Although proxies of patients with chronic obstructive pulmonary disease (COPD) need health-related knowledge to support patients in managing their disease, their current level of knowledge remains unknown. We aimed to compare health-related knowledge (generic and COPD-related knowledge) between patients with COPD and their resident proxies.

Methods: In this cross-sectional study, we included stable patients with moderate to very severe COPD and their resident proxies (n = 194 couples).

Health Status and Morbidities in Resident Relatives of Patients With COPD.

Objectives: Resident relatives of patients with chronic obstructive pulmonary disease (COPD) may play a major role in obtaining a healthy lifestyle for patients. Little is known about resident relatives. This study aimed to compare health status, morbidities, care dependency, and mobility between patients with COPD and their resident relatives.

Thalidomide versus active supportive care for maintenance in patients with malignant mesothelioma after first-line chemotherapy (NVALT 5): an open-label, multicentre, randomised phase 3 study.

Background: Standard chemotherapy does not lead to long-term survival in patients with malignant pleural mesothelioma. Malignant pleural mesothelioma is strongly dependent on vasculature with high vessel counts and high concentrations of serum vascular growth factors. Thalidomide has shown antiangiogenic activity, and we hypothesised that its use in the maintenance setting could improve outcomes.

[Interstitial pneumonitis as an adverse effect of thalidomide].

A 67-year-old man was admitted to the hospital with symptoms of progressive dyspnoea. For 2 months he had received second-line treatment with dexamethasone and thalidomide for a multiple myeloma. Physical examination revealed a tachypnoeic patient and arterial blood gas analysis revealed a respiratory alkalosis and severe hypoxaemia.

Thalidomide in patients with malignant pleural mesothelioma.

Objectives: The purpose of this study was to describe the experience with the anti-angiogenic agent thalidomide in the treatment of patients with a malignant pleural mesothelioma (MPM).

Materials And Methods: Patients with a histological confirmed diagnosis of malignant mesothelioma received thalidomide orally at night. Increasing doses of 100, 200 or maximally 400 mg were given till progression or unacceptable toxicity.

Pharmacodynamic steady state of tiotropium in patients with chronic obstructive pulmonary disease.

Tiotropium (Spiriva) is a new once-daily inhaled anticholinergic that has its effect through prolonged muscarinic (M)3 receptor antagonism. It has a clinically documented, long duration of action with once-daily dosing in chronic obstructive pulmonary disease (COPD). A single-centre, double-blind, ipratropium-controlled study was conducted in order to characterize the onset of pharmacodynamic steady state of tiotropium in patients with COPD.

['Trigger thumb' in 38 children: good short-term and long-term results from surgery].

Objective: To determine the direct and long-term effectivity of incision of the pulley in a trigger thumb (tendovaginitis stenosans).

Design: Retrospective study with follow-up.

Methods: In the period 1984-1995, 38 children (24 boys and 14 girls) were diagnosed and operated on 45 trigger thumbs in the Onze Lieve Vrouwe Gasthuis (Amsterdam) and Medisch Centrum Alkmaar, the Netherlands.

Radiosynthesis and biodistribution of 123I-labeled antagonists of the histamine H3 receptor as potential SPECT ligands.

We have synthesized three 123I-labeled histamine H3 receptor ligands, i.e., [123I]GR 190028, [123I]FUB 271, and [123I]iodoproxyfan, in moderate to good radiochemical yields via a Cu+-assisted I-for-123I exchange method.

Vesamicol and some of its derivatives: questionable ligands for selectively labelling acetylcholine transporters in rat brain.

Presynaptic cholinergic markers could be used for estimating the integrity of the cholinergic systems in the human brain with brain imaging techniques such as Single-photon emission computed tomography (SPECT). Vesamicol, an inhibitor of the vesicular acetylcholine transporter, and some of its derivatives have been suggested as potential ligands for this purpose. However, vesamicol binds not only to acetylcholine transporters but also to sigma binding sites.

A simple and efficient method to remove free radioiodide from *I-radiopharmaceuticals.

Removal of free radioiodide from *I-radiopharmaceuticals was easily performed by using a pure metallic silver membrane, placed in a screwable holder. Well-known radiopharmaceuticals such as 3-iodobenzylguanidine, Hippuran, iomazenil and fatty acids were treated successfully, and gave reproducible results. Only a trace of free radioiodide (< or = 1%) was left after passing the silver membrane, while rest activity due to retention of the radiopharmaceutical on the membrane was negligible (2%-5%).

Comparison of performance of four instruments in evaluating the effects of salmeterol on asthma quality of life.

Quality of life measures are increasingly used as important efficacy endpoints in studies of drugs for asthma. The purpose of this study was to assess both the sensitivity to change and the construct validity of four different quality of life instruments in patients with asthma. In a double-blind, parallel group study, 120 moderate asthma patients, aged between 18-70 yrs, received either inhaled salmeterol 50 micrograms b.
