Objective: To evaluate the feasibility of using combined clinical and histomorphometric features to construct a prognostic score for the individual patient with localized renal cell carcinoma.
Patients and Methods: We studied 39 patients with pT1 and pT2 RCC who underwent radical nephrectomy between 1974 and 1983. Univariate and multivariate analyses were used to determine the association between various prognostic features and patient survival.
Results: The most important and independent predictors of survival were tumor angiogenesis (P=0.009), nuclear DNA ploidy (P=0.0071), mean nuclear area (P=0.013), and mean elongation factor (P=0.0346). Combination of these variables enabled prediction of outcome for the individual patient at a sensitivity and specificity of 78% and 89% respectively.
Conclusion: Our results indicate that no single parameter can accurately predict the outcome for patients with localized RCC. Combination of neovascularity, DNA content and morphometric shape descriptors enabled a more precise stratification of the patients into different risk categories.

Background: Proximal femur fractures represent a challenging medical problem worldwide. In recent years numerous reports have documented. a progressive increase in the incidence of hip fractures. In Jordan, this problem has not received sufficient attention, and to my knowledge, this is the first study to address the problem.
Objective: To analyze the predisposing factors involved in the occurrence of proximal femur fractures seen at a major medical center in Jordan.
Methods: A retrospective analysis was conducts of all patient admitted with hip fractures to King Hussein Hospital and the Royal Jordanian Rehabilitation Center at the King Hussein Medical Center over a 2 year period (1 January 1995 to 31 December 1996). We determined the associated chronic diseases and medications, mechanisms of injury, types of fractures and other circumstances in order to suggest preventive measures to decrease the incidence of this clinical problem.
Results: We identified 216 cases of fracture: 43% occurred in people over the age of 80 years, 95% were due to low energy injuries (falls), and 69.5% occurred in females. Two or more co-morbid medical conditions were present in 70% of the cases.
Conclusion: Since fractures of the hip in the study population in Jordan occurred predominantly as low energy injuries in the elderly, preventive measures should focus on fall avoidance.

Background: Secundum atrial septal defect is a common congenital heart defect that causes right heart volume overload and produces symptoms usually after the third decade of life. Treatment until the last few years has been open heart surgery.
Objective: To review our early experience with transcatheter closure of ASD2 using the Amplatzer septal occluder.
Methods: Between November 1999 and February 2000, 20 children and young adults with a median age of 9.1 years (4.2-35.1 years) were referred for transcatheter closure of ASD2. Diagnosis was established by transthoracic echocardiography. Implantation was performed under general anesthesia through the femoral vein with the guidance of transesophageal echocardiography and fluoroscopy. Femoral arterial puncture was performed for blood pressure monitoring during the procedure. The device size chosen was similar to the balloon-stretched diameter of the ASD2.
Results: Implantation was completed successfully in 18 patients. Two patients were referred for elective surgery: one had an unsuitable anatomy for transcatheter closure by TEE in the catheterization laboratory and the device could not implanted properly, the other patient had a large multiperforated septal aneurysm that was retrieved. Mean ASD2 diameter by TTE and TEE was similar (13.9 + 3 mm, 13.4 + 3.5 mm) and mean stretched diameter was 18.3 + 4.3 mm. Mean Qp:Qs (pulmonary flow: systemic flow) was 2.2 + 0.6. Mean fluoroscopy time for the procedure was 14.8 + 4.8 minutes.
The patients were discharged the day after the procedure.
Four patients had a tiny leak immediately post-procedure, and none had a leak at one month follow-up. The only complication was a small pseudoaneurysm of the femoral artery in one patient, that resolved spontaneously.
Conclusion: Transcatheter closure of ASD2 with the Amplatzer septal occluder is a safe and effective alternative to surgical closure. Long-term outcome has to be evaluated.
