Psychosomatic evaluation of patients with congenital penile deviation. A postoperative catamnestic follow-up.

Thirty-three patients with congenital penile deviation were examined by a semi-structured interview and psychodiagnostic tests (Giessen test, Giessen complaint sheet) prior to undergoing surgery according to the Nesbit-Kelâmi technique. A prognosis was then made to determine the extent to which the problems and disturbances reported by the patient or uncovered by the examiner could be improved by the operation. This prognostic assessment was then verified in a subsequent catamnestic examination (N = 20), at an average of 21.3 months after the intervention. An attempt is made to identify and define preoperative indicators that permit to predict the postoperative course.

A two-year reject/retake profile analysis in pediatric radiology.

With increasing interest in the use of reject/retake analysis as an integral part of a routine quality assurance program in diagnostic radiology comes the need for a better understanding of the information obtained. The present study investigated the reject/retake profiles in a pediatric radiology department on a long-term basis. Retake profiles have been continually analyzed for a period of 24 months. Emphasis of the analysis were placed upon understanding the characteristics of the profiles observed and the effectiveness of the corrective actions implemented. The analysis indicated that after the implementation of a comprehensive quality assurance program, the overall rejection profile is predominantly determined by the rate of positioning errors.

Routine skin dose calculation using a desk-top calculator.

A program that calculates the patient skin dose was developed using a programmable desk-top calculator (Hewlett-Packard HP-97). The calculation scheme is based upon the technique factors used for the radiographic examination and the radiation output characteristics of the x-ray generating devices. Thermoluminescent dosimetry (TLD) was used on some clinical examinations and phantoms to establish the validity of this program. The average percentage difference between the TLD results and the calculated values is less than 15 per cent. The program listing is available from the author upon request.
