[Operative treatment of proximal humeral four-part fractures in elderly patients: comparison of two angular-stable implant systems].

Aim: Although being one of the most common fractures in elderly patients, there is still no standardised treatment protocol for four-part fractures of the proximal humerus. However, a wide variety of angular-stable implants is available. The present retrospective study compares the clinical and radiological outcome following operative treatment of four-part fractures of the proximal humerus with the Philos system (Philos, proximal humeral internal locking system, Synthes GmbH, Umkirch Germany) and the angular-stable Königsee plate system (Königsee Implantate GmbH, Allendorf, Germany) in patients older than 65 years.

[Relation of the family physician to his patient and evaluation of the patient: aspects of willingness to comply?].

This study was conducted to examine the influence of general practitioner's behavior (i.e. the patient-centered behavior) on patients' inferences as well as on patient's compliance.

[Speech and conviction as determinants of behavior and perception in interactions: an example of physician-patient relations].

We report on a simulation study with 72 student subjects as well as on an inquiry of 58 patients on the doctor-patient interaction. We were especially interested in inferences that patients draw from general practitioners' behaviors, i.e.

[Medicamentous obstetric analgesia with pentazocine in comparison with an untreated control group].

In order to establish whether a powerful analgesic such as pentazocine administered during birth may damage the child or have negative influence on the course of birth, the course of delivery was studied in 40 patients, 20 of whom were given a single dose of 30 mg pentazocine administered intramuscularly. There were no differences in duration of birth, CTG, blood gases post partum, or Apgar scores as compared to the untreated control group. As regards the pharmacokinetics, the serum pentazocine levels of the gravidae corresponded to those found in non-pregnant subjects; the levels found in blood from umbilical cords and new-borns were at the lower limit of detectability.

The effect of pH and temperature on the stability and enzymatic activity of prostatic acid phosphatase. Studies on the optimization of a continuous monitored determination of acid phosphatase, II.

The catalytic activity and the stability of prostatic acid phosphatase were studied with respect to pH and temperature: 1. Enzymatic activity in serum decreases with time, and the rate of decrease depends on pH and temperature. Half life times were estimated.
