Phytohemagglutinin skin testing in critically ill surgical patients.

Phytohemagglutinin (PHA) skin tests were performed in 225 critically ill surgical patients with respiratory failure. The study population was composed of 68 trauma patients who had suffered severe multiple injuries and 157 nontrauma patients who had a variety of surgical complications. The initial skin test response, obtained at the beginning of mechanical ventilation, was negative in 31% of the trauma patients and in 49% of the nontrauma patients. In the group of trauma patients, a higher mortality rate was noted in negative initial skin test responders compared with positive initial responders (38 and 15%, respectively; p less than 0.05). In the group of nontrauma patients, no association could be demonstrated between skin test unresponsiveness and mortality. With sequential testing, most (70%) of the patients were found to show at least one negative skin test reaction while in the intensive care unit. There was no difference in mortality between patients who remained reactive to PHA and patients with one or more negative skin test responses. These findings show that surgical intensive care patients frequently have an impaired cellular immunocompetence as indicated by a failed skin test response to PHA. However, PHA skin testing has little or no value in predicting outcome in these patients.

[Treatment of stress urinary incontinence. Should it be operated using high or low approach?].

This paper presents a review of various studies comparing surgical techniques using upper or lower approaches for the treatment of urinary stress incontinence with urethral insufficiency. The results are analysed and compared using the case history as well as the clinical and urodynamic examination as criteria for success. The superiority of procedures using the upper approach gives them a distinct advantage over lower approach procedures. The importance of an improved transmission factor following procedures which use the upper approach is emphasized. Finally, the factors involved in selecting the proper surgical procedure for correction of the anatomical impairments are summarized.

[Cystometry: comparative values of water manometry and the "Mikro-Tip" method in the assessment of urinary stress incontinence].

Urethro-cystometry carried out on 20 patients with urinary stress incontinence which was clinically apparent gives quite different results if it is carried out using the water manometry technique of Bech-Heidenreich or using a Mikro-Tip technique without perfusion. Comparing the two techniques shows: --little or no difference in the measurement of the functional length of the urethra and the maximum pressure of closure of the urethra. --no difference between the form of the urethral surface at rest and the bladder surface on effort. --on the other hand it shows a very definite difference in the urethral surfaces on effort which depends on the large differences occasioned by the transmission factor. The latter is weak with the Heidenreich method and corresponds to the clinical state; it is raised with the micro-tip method, which contradicts the clinical evidence.
