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.

In recent years liver transplantation was shown to be the only clinically effective method of treating acute or chronic hepatic failure due to various causes. However, this ultimate therapeutic approach is limited by the growing disparity between organ donation and the number of patient on the waiting list.

Factors such as high cost, morbidity, and the need for lifelong immunosuppression accelerated the research on alternative methods to support the failing liver. Recently, new technologies incorporating hepatocytes and extracorporal circulation devices were introduced for liver support systems and their role in the treatment of acute liver failure.

Background: The free-to-total prostate-specificantigen ratio is the best marker for optimizing prostate cancer detection. The main problem with studies of percent free PSA is the variability of reported cutoff values.

Objectives: To evaluate the influence of prostate size on the ratio of free to total PSA.

Methods: The study group included 58 patients (mean age 66.4 years) with clinically localized prostate cancer treated surgically at our institution. Total PSA and free PSA levels were measured by a solid phase enzyme immunoassay test (Hoffman-La Roche, Basel, Switzerland). The percent free PSA was compared with prostate size as determined from the surgical specimen.

Results: A direct relation was noted between prostate size and the percent free PSA value (r=0.49, P=0.0001). Mean percentage free PSA was 9%0.004 in men with normal-sized gland while in men with large prostate (60 g) the average percent free PSA was 15.90.09 (P=0.001).

Conclusions: In patients with prostate cancer the percent free PSA level is influenced by the gland size. The larger the prostate the higher the proportion of the free PSA. Such information may have influence on the recommendation for prostate biopsy in screening programs for early detection of prostate cancer.

 Background: Cigarette smoking has long beenregarded as an important factor in the pathogenesis of peptic ulcer disease.

Objective: To investigate whether cigarette smoking has an additive effect on the clinical presentation and course of disease in Helicobacter pylori-positive dyspeptic patients.

Patients and Methods: The study group comprised 596 consecutive H. pylori-positive dyspeptic patients (334 males and 262 females, mean age 50.6, range 12--81 years). Following upper gastrointestinal endoscopy, patients were subdivided by diagnosis as follows: Non-ulcer patient group (n=312: gastritis 193, duodenitis 119), gastric ulcer (n=19), and duodenal ulcer (n=265). H. pylori infection was confirmed by histology and/or rapid urease test. In addition, 244 patients had a positive 14C-urea breath test prior to antimicrobial treatment. The patients' medical history and smoking habits were obtained using a detailed questionnaire completed by the patients and their referring physicians.

Results: There were 337 non-smoking patients, 148 current smokers and 111 past smokers. Gastric and duodenal ulcers were significantly less prevalent in non-smokers than in current or past smokers (gastric 1.8%, 4.1%, 6.3%; duodenal 39.8%, 50%, 51.4%, respectively) (P0.05). The incidence of gastrointestinal bleeding was significantly lower in non-smokers than in current or past smokers (7.1%, 8.1% and 20.7%, respectively) (P0.05). Bacterial density, as assessed by the UBT value in 244 patients, was higher in non-smokers (mean 352.3273 units) than in past smokers (mean 320.8199) or current-smokers (mean 229.9162) (P0.05). Logistic regression analysis revealed that male gender, current smoking, and immigration from developing countries were all significant independent risks for developing duodenal ulcer, while only past smoking was associated with a higher rate of upper gastrointestinal bleeding in the past.

Conclusions: In H. pylori-positive dyspeptic patients, current smoking as well as male gender and immigration from developing countries are associated with an increased risk for duodenal ulcer. This effect does not seem to be related to the bacterial density or increased urease activity of H. pylori organisms.

 As the twenty-first century begins it becomes increasingly apparent that the twentieth century, which opened with the promise of the eradication of most infectious diseases, closed with the specter of the reemergence of many deadly infectious diseases that have a rapidly increasing incidence and geographic range. Equally if not more alarming is the appearance of new infectious diseases that have become major sources of morbidity and mortality. Among recent examples are HIV/AIDS, hantavirus pulmonary syndrome, Lyme disease, hemolytic uremic syndrome (caused by a strain of Escherichia coli), Rift Valley fever, Dengue hemorrhagic fever, malaria, cryptosporidiosis, and schistosomiasis. The reasons for this situation are easily identified in some cases as associated with treatment modalities (permissive use of antibiotics), the industrial use of antibiotics, demographic changes, societal behavior patterns, changes in ecology, global warming, the inability to deliver minimal health care and the neglect of well-established public health priorities. In addition is the emergence of diseases of another type. We have begun to characterize the potential microbial etiology of what has historically been referred to as chronic diseases.
