Late results of traumatic posterior dislocation of the hip joint [type I]

A retrospective study was undertaken to evaluate the late results and complications of the management of traumatic posterior dislocation of the hip joint Thompson Epstein type I. Twenty-five patients were followed up for an average period of 3.5 years, where these patients were evaluated by standard questionnaire, clinical and radiological examinations. The final clinical and radiological criteria were assessed and graded according to Epstein and Pennal et al. grading system. The overall results and the effect of each of many factors were analyzed for their statistical significance. The overall results were excellent in 64% of the cases, good in 16%, fair in 8% and poor in 12%. Thus, overall satisfactory results were achieved in 80%, while overall unsatisfactory results were achieved in 20%. The most important factors significantly affecting the final results were the time lapse before reduction and the type of aftercare. Regarding the long-term complications, post-traumatic arthritis was the only late complication and it was the main cause of unsatisfactory results

Some epidemmiological aspects of patients with end stage renal diseases

This study was carried out to describe the end stage renal disease [ESRD] among Egyptian patients and to identify the possible risk factors of their disease. A case-control study was conducted with two control groups [patient or hospital control group and normal community control group] compared with ESRD cases on hemodialysis. The study revealed that hypertension followed by obstructive uropathy are the leading causes of ESRD. Conducting the multiple logistic regression analysis, the following factors were found to act independently as risk factors for ESRD in the following order of importance: Past history of hypertension, family history of renal failure, past history of renal pain, smoking, urban origin of birth, past history of renal or urinary stones, past history of schistosomiasis, the presence of a near-by residential factory and past history of frequent hospitalization. A quality of life score has been invented

Estimation of ventricular DP/DT by continuous wave doppler echocardiography

The present study was carried alit on 30 patients in sinus rhythm with mitral regurgitation, twenty patients have rheumatic heart disease "group I" five have dilated cardiomyopathy "group II" and five have ischemic heart disease "group III". To drive Doppler RRR, two points were arbitrarily selected on the steepest rising segment of the CW mitral regurgitation velocity curve "point A [ml/sec,] point B [3m/sec]" and the time interval between them was measured. Following Benroulli equation, the pressure rise between point A and B is 32 mmHg "4VB2-4VA2" and the rate of pressure rise is 32 mmHg/t. Peak dp/dt obtained at cardiac catheterization by dividing the ascending limb of LV pressure curve into segments of equal time intervals of 40 msec. The pressure rise during these intervals is divided by these intervals P/40 msec to obtain dp/dt. The highest value is the peak dp/dt. We obtained the following group I: Analysis of this group shows no statistically significant difference between results obtained by both methods P0.05 with a good correlation coefficient "r = 0.83". Group II: an excellent correlation coefficient " r=0.98 ". Group III "r=0.97"
