We report the case of a 43-yr-old car painter who died within 1 h of exposure to a polyurethane paint in the workplace. A diagnosis of asthma induced by toluene diisocyanate (TDI) had been established 6 yr before, when he underwent inhalation challenges with carbachol and with TDI. The subject had airway hyperresponsiveness to carbachol (PD20FEV1 carbachol = 0.32 mg; normal value greater than 1.0 mg) and developed an early and long-lasting asthmatic reaction after exposure to TDI in the laboratory. Although it was recommended that he change his job or stop using paints containing isocyanates, he continued to work as a car painter, taking antiasthmatic drugs both at work and at home to control asthma symptoms. On Monday, October 6, 1986, at 11:30 A. M., he developed a severe attack of asthma while he was mixing the 2 components of a polyurethane paint. Taken to hospital, he was dead on arrival. Autopsy showed no evidence of cardiac or brain disease; lungs were overinflated, the cut surface showed grey glistening mucous plugs in in the airways. Histologic examination showed denudation of airway epithelium and thickening of the basement membrane with infiltration of the lamina propria by polymorphonuclear leukocytes, mainly eosinophils, and diffuse mucous plugging of bronchioles. Bronchial smooth muscle appeared hyperplastic and disarrayed, and lung parenchyma showed focal areas of alveolar destruction adjacent to areas of perfectly intact alveolar walls.(ABSTRACT TRUNCATED AT 250 WORDS)

We describe 2 adult patients with acute lymphoblastic leukaemia (ALL) who died from pulmonary embolism following L-asparaginase treatment. Since this drug is known to cause a decrease in antithrombin III, the most important protein physiologically involved in the neutralization of thrombin, we studied the behaviour of this inhibitor in 14 ALL patients treated with a protocol including a 14-day course of L-asparaginase. A significant but transient fall of biological and immunological antithrombin III and a concomitant reduction of fibrinogen were documented.

Intravesical mesh erosion can complicate sling procedure. Endoscopic holmium laser management is a useful treatment for mesh removal and stone lithotripsy. Repeated treatments are possible for the low morbidity and minimal invasiveness. A regular follow-up is necessary.

The subject of this paper is a 2-year-old child with progressive paraparesis. MRI showed a large lumbosacral intradural-extramedullary mass and the histological diagnosis was Langerhans cell histiocytosis. The histopathological and neuroradiological findings are discussed.

The aim of the paper is to compare the pre-operative and postoperative urodynamic parameters of women with stress incontinence undergoing a TVT (Tension-free Vaginal Tape) operation in order to evaluate the functional dynamics of the operation. Twenty-two patients (mean age 56.3 years, range 30-69 years) underwent the TVT operation for the correction of stress urinary incontinence. Cervical urethral hypermobility was present in all the patients and only the TVT operation and no other surgical procedure was performed. The main urodynamic modification was the improved transmission pressure to the urethra (CTU%) at the post-operative check up, although the maximum urethral closure pressure (MUCP), the functional length (FL) and the maximum flow (Qmax) remained unchanged
