    ABSTRACT: This is a retrospective study of all patients admitted to Basma Teaching Hospital with a diagnosis of fever of unknown origin (FUO). The study took place from January 1995 to December 2001. Fifty-two patients fulfilled the criteria of FUO. Infections were responsible for 26 cases (50%), malignancy for eight cases (15%), connective tissue disorder for six cases (12%) and others for 12 cases (23%). Infections remain the most common causes of FUO in Jordan, mainly tuberculosis, brucellosis and typhoid fever.

    ABSTRACT: Studies have shown the safety and effectiveness of laparoscopic cholecystectomy (LC) for acute cholecystitis (AC). Our aim was to establish the outcome of LC in patients with AC on the basis of duration of the attack before surgery took place, the type of gallbladder inflammation, and patient sex. All 204 patients at Princess Basma Teaching Hospital who underwent LC for AC by the authors between September 1994 and June 1999, were retrospectively reviewed. They were categorized into Group I, where surgery took place within 72 hours of the acute attack (N = 78; 54 women and 24 men), and Group II, if later than that (N = 126; 70 women and 56 men). Gallbladder pathology was classified as gangrenous, empyema, edematous, mucocele, or AC along with contracted fibrosed gallbladder. Conversion to open cholecystectomy was needed in 12% of the total series. In Group I, 3.8% of the patients needed conversion compared with 16.7% in Group II patients (P = 0.01). Also, 4% of the female patients needed conversion compared with 24% of the male patients (P = 0.000). There was an association between the pathological type of AC and the likelihood of conversion (P = 0.002), conversion being least common in those with mucocele and most common in those with empyema and gangrene. The median operation time was 75 +/- 36 minutes, but the operation time for Group II patients was significantly longer (P = 0.001) than in Group I patients. Operation time in the male patients was significantly longer than in the female patients (P = 0.000). There was no statistically significant difference in the duration of hospital stay in the two groups or in men and women. There were no deaths or main bile duct injuries in the series. In successful LC, missed stones occurred in 3.3% of the patients. Bile collection, which was treated by open surgery, developed in one female patient. Laparoscopic cholecystectomy is a reliable and safe modality for the management of AC. It was not associated with an increased incidence of bile duct injury in this series. It should be the first choice before resorting to open surgery. Factors associated with increased conversion include delay in surgery of more than 3 days from the acute attack and certain pathology, with conversion being more likely in empyema. Conversion also was more likely in male patients.

    ABSTRACT: Laparoscopic cholecystectomy (LC) is now a common method of treating symptomatic gallstones, and it is increasingly being requested by the informed general public. Our aim was to evaluate the role of LC for cholelithiasis and to establish its outcome and the effect of gender on the results. Between September 1994 and June 1999, all patients who underwent LC for cholelithiasis were retrospectively reviewed. They were classified as having acute or chronic cholecystitis (AC or CC). There were 791 patients with CC (633 females, 158 males) and 204 patients with AC (124 females, 80 males). Conversion to open cholecystectomy was needed in 0.76% and 11.8% of the patients with CC and AC, respectively (P<0.00). Four percent of the female patients with AC needed conversion as compared to 23.8% in the males (P<0.00). The low conversion rate in CC limited gender comparison. Median operation time in the patients with CC was 53+/-16 minutes as compared to 74.5+/-35.7 minutes in those with AC (P<0.00). Operation time in the male patients with CC and AC was significantly higher than in the female patients, even after excluding the converted cases (P<0.00). Median postoperative stay for patients with CC was 1.33+/-0.9 days as compared to 1.9+/-1.34 days in patients with AC (P<0.00). No statistical significance in the hospital stay was found between males and females (in CC and AC). There was no mortality in the series. There were three bile duct injuries in the patients with CC. In patients with successful LC, gallbladder perforation occurred in 18% and 31% of CC and AC patients, respectively (P<0.003). Missed stones occurred in 1.4% and 3.3% of the patients with successful LC for CC and AC, respectively. Bile collection, which was treated with open drainage, occurred in four patients with CC and one patient with AC. LC for symptomatic cholelithiasis is safe and feasible; it should be the first choice before resorting to open surgery. In patients with AC as compared to CC, there is an increased conversion rate, longer operation time, longer hospital stay, and higher incidence of gallbladder perforation without an increase in the incidence of bile duct injuries (BDI). Male patients have a longer operation time and higher conversion rate than female patients.

    ABSTRACT: An attempt was made by the Jordanian National Center for Diabetes, Endocrine and Genetic Diseases (NCDEGD) to identify all cases of type 1 diabetes among Jordanian children aged 0-14 y. Data were obtained retrospectively for the years 1992-1994 and prospectively for the years 1995 and 1996, including full name, national identifying number, date of birth, date of diagnosis and family history. The incidence was calculated as the number of cases per 100,000 population, according to the national census of 1994. The incidence rate for these years (1992 through 1996) was 2.8, 2.9, 3.2, 3.6 and 3.6 per 100,000 population, respectively. The male:female ratio was (1:1.03). Seasonal variation at clinical onset was noticed, with maximum incidence in the winter months and minimum incidence in the summer months. In conclusion, the incidence of type 1 diabetes mellitus in Jordanian children aged 0-14 y is among the lowest in the region, but is rising.

    ABSTRACT: The objective of the study was to determine the conversion rate of subjects with impaired glucose tolerance (IGT) to Type 2 diabetes mellitus (NIDDM) and to identify factors which predict such conversion.Sixty eight subjects previously diagnosed with IGT in a survey conducted in 1995 in Sikhra, a Jordanian town of 10,000 people located in North Jordan, were reassessed for conversion to Type 2 diabetes two years later. A control group of 144 participants in the 1995 survey with normal glucose tolerance was also similarly reassessed for conversion to Type 2 diabetes. Diagnosis of IGT and NIDDM was based on WHO criteria1.Of the 68 IGT cases, 10 (14.7%) progressed to Type 2 diabetes, 27 (29.7%) reverted to normal, and the remainder persisted with IGT. A positive family history was a significant predictor of progression to diabetes irrespective of the IGT status. During the two year follow-up period a significantly larger increase in systolic blood pressure (SBP) was observed among those who progressed to Type 2 diabetes compared with those who did not. Age ±40 and hypertension were consistent with a higher rate of progression to Type 2 diabetes but the association failed to attain statistical significance at the 0.05 level (p = 0.055 and 0.07 respectively).

    ABSTRACT: This study aims to evaluate cancer of the large bowel as it occurred in a defined Jordanian population, with special reference to its epidemiologic aspects. Second, this study was undertaken to compare these results with those of other countries and those previously reported from Jordan. Records of patients diagnosed as having colorectal adenocarcinoma during a six-year period in Irbid province, Jordan, were reviewed. The material was analyzed retrospectively with respect to various epidemiologic features, and the results were compared with those of other countries and those previously published about the Jordanian population. Between January 1990 and December 1995, 109 new patients with colorectal adenocarcinoma were managed, an incidence of 3.8/100,000/year. Male to female ratio was 1:1.05 for colonic cancer and 1.36:1 for rectal cancer. The maximum incidence was seen in the sixth and seventh decades. A total of 12.8 percent of the patients were younger than 40 years of age. The rectum was the most common site involved in 30.3 percent of the patients, followed by the sigmoid, right colon, and the rest of the colon. When compared with previous Jordanian figures, a shift toward the western figures was noted. The delay in diagnosis was noted from the 8.2 months of delay before diagnosis and the advanced stage of the disease at the time of diagnosis. A total of 49.5 percent of the cases were in Dukes B stage, 30.3 percent in Dukes C, and 19.3 percent in Dukes D. Only one patient was in Dukes A stage. A total of 13.8 percent of the cases were mucinous adenocarcinoma. A total of 26.5 percent of the patients presented with complications. As for colorectal adenocarcinoma, we still share the epidemiologic characteristics of developing countries, but there is a shift toward those of western communities. Flexible sigmoidoscopy is encouraged for evaluation of lower gastrointestinal symptoms, and education of the public and medical staff about colorectal diseases is needed to improve the outcome.

    ABSTRACT: This study reports the outcome of real-time ultrasonographic screening tests of a healthy population. The study group consisted of 33 female teachers who were found to have asymptomatic gallstone disease. All cases were followed up to determine the incidence of biliary colic or complications. After a 38-month period of follow-up, seven subjects (21.2%) developed either biliary colic or complication. Study results revealed that the 38-month cumulative probability of the development of biliary colic or complication was 36%. Data shown that development of biliary colic or complications was positively associated with obesity, but no assocition was found with age, number of activities, or duration of contraceptive pill-taking. Having such a high percentage of subjects who developed biliary colic or complications within a relatively short period of time suggests that the silent gallstone is not innocent.

    ABSTRACT: This retrospective study covers the authors' experience over five years of 1,722 primary hernia repairs in 1,722 patients of all ages. An analysis of some epidemiological features is presented and discussed. Inguinal hernia was by far the commonest variety accounting for more than 84% of the total series. Regardless of sex and type of hernia, 60% of all hernias were right-sided while not more than 5% were bilateral. The male to female ratio for the entire series was 4.3:1 and 8.2:1 for the inguinal hernia group. The main findings of this retrospective study are in direct accord with other series reported in the literature. Furthermore, we suspect our results are typical of those to be found in large and comparable general community hospitals in Jordan.

    ABSTRACT: Twenty-two infants suffering from infantile hypertrophic pyloric stenosis underwent Ramstedt's pyloromyotomy using circumumbilical incision. There was no difficulty in delivering the pylorus out of the incision. Three patients developed wound infection, one patient developed wound dehiscence at the fascial plane and one patient developed stitch sinus. No incisional hernias were noted after a follow-up period ranging from 2 months to 4 years (mean 27 months). All scars were neat except that of the patient who developed wound dehiscence at the fascial plane and another who developed stitch sinus. This incision is cosmetic and gives access that is almost comparable to other incisions without a significant increase in the morbidity rate.

    ABSTRACT: The objective of this study is to report our experience in the management of pulmonary hydatid disease. Fourteen patients, 6 females and 8 males, ranging in age from 6 to 35 years were seen over a period of 7 years at a Princess Basma Teaching Hospital. Most of them had a single and isolated primary lung cyst. All patients were treated by the open method without resection through a posterolateral thoracotomy. Follow-up was maintained for 5 years with chest X-ray and indirect haemagglutination test performed annually. In conclusion, the lung-preserving operation without resection or capitonnage is the treatment of choice for pulmonary hydatid disease.
