Because the mortality rates and incidence rates of specific pediatric tumors vary with demographic features in many countries, this study has been conducted to determine the magnitude of childhood malignancy in Benghazi and Eastern area of Libya where 163 confirmed cases of childhood malignancies were studied retrospectively from January 1996 to December 1999. The majority of cases were found from Benghazi and Eastern area (82.8%) (Because the cases from the west and south are treated in Tripoli). Most of them were in the preschool age. Malignancies were more common in males with total male to female ratio of 1.18: 1. Most of the cases from Benghazi were Leukemias (27/77=35%), while in the Eastern area most of cases were Lymphomas (20/58=34.5%). Because some tumors are underestimated, there is certainly an urgent need to establish national registration centers.

This retrospective study was carried out in the neonatal unit of Al-Fateh Children Hospital in Benghazi. Over a 12 month period, 317 full term newborns were admitted because of jaundice; 30% of them had ABO incompatibility, while 51% had no apparent cause for jaundice. All newborns were treated with phototherapy with no complications and 60 newborns were treated with 65 exchange transfusion. Only one newborn developed kernicterus; her serum bilirubin was 46mg/dl. Risk factors of hyperbilirubinemia among our newborns were: family history of jaundice (30%), and exchange transfusion (5.6%), breast milk feeding (53%), male sex (63%) and 12.5% of newborns born to Rh negative mothers. Early recognition of newborns at risk of hyperbilirubinemia and measurement of serum bilirubin in the first 24 hours of life will improve management of neonatal jaundice.

Endoscopy clinic of 2nd march hospital is the only endoscopic facility in the south of Libya, patients are referred for diagnosis and management of upper and lower gastrointestinal problems. As most the patients are travelling long distances and most of times are self-driving so sedation or anesthesia are not suitable for them. That fact and reviewing of some papers concerning endoscopy without sedation enhance us to adapt this procedure, and here we are assessing our results. 1406 patients attended the clinic in 3 years period, between may, 13th, 1999 till march, 12th, 2002, using end view Olympus gastroscope (GIF-Q) Tolerance of procedure, fear, anxiety, failure, and overall success, were assessed. Most of the patients complete the procedure, only twenty-three failures (1.6 %), while 1297 patients (92.2 %) complete the procedure comfortably, introductions of the endoscope were easy, there were no complications.

Objective: To determine incidence and risk factors for stroke in the Fezzan region, South Libya. Setting: 2 nd March Teaching Hospital, Sebha, South Libya. Methods: This was a prospective hospital-based study of stroke patients admitted to 2nd March Teaching Hospital during a period from January 2001 to December 2001. Results: Two hundred and thirty-two patients were admitted due to stroke during the study period to give an average annual incidence rate of 662 per 100000 deaths. One hundred and thirty patients (56%) were male. The mean age was 61± 16years. The 30-days case morality rate was 22.4%. A diagnosis of brain infarction was made in 182 patients (78.4%). Of the remainder, intracerebral hemorrhage accounted for 13.4% and subarachnosis hemorrhage for 3.4%. Among risk factors hypertension (66.3%) overshadowed the rest. Cardiac disease (34.3%) was the second common risk factor. Conclusion: The incidence of stroke is high in South Libya. Therefore, active programs need to be initiated to identify risk factors in the population at large. Upon identification effective therapy should be introduced and maintained.

A retrospective study on 580 patients, was carried out at 7th October renal OPD over a 9 months period from 1.10.97 to 30.6.98 to know the pattern of renal disorders, in order to plan suitable medical preventive measures to decrease the incidence of some of them, with consequent effects on end stage renal disease (ESRD ) problem in the community. Analysis of the patients data showed that 76 patients of the total studied group (13.2%) had chronic renal failure (CRF) on conservative treatment (group 1) patients. The remaining 504 patients who constituted (86.8%) of the total studied group had normal RFT (group 2) patients. Diabetes mellitus and/or hypertension were diagnosed in a total of 49 patients of group I (64%) and a total of 88 patients of group 2 (17.5%). UTIs were diagnosed in a total of 378 patients of group 2 (75%). The overall UTIs uncomplicated and complicated cases were diagnosed in 386 patients of the total studied groups (67%) and female constituted (52%) of the total UTI cases. So the pattern of renal disorders in our patients, is similar to that seen in the other parts of the world with slight increase in prevalence rates of UTI, and chronic renal failure especially secondary to HBP and/or D.M

Rheumatoid Arthritis is a multi-systemic disease with a variety of extra-articular manifestations. On occasion, they may be the major evidence of disease activity and a source of morbidity, and require management per se. As a rule, these manifestations occur in patients with high titers of RF. This study was undertaken to determine the prevalence of the extraarticular manifestations in our clinic, and to compare it with figures from other countries. This study was performed on (115) patients who met the ARA criteria in 1987 for RA. Ninety-nine patients were females (86.08%), (16) patients were males (13.9%). Age ranged from (14-75 yrs) with a mean age of (41.5 yrs). One –hundred and thirteen patients were white (98.2%) and (2) patients (1.73%) were black. The RF was positive in (97) patients (84.3%), and negative in (18) patients (15.6%). These patients were assessed for extra-articular manifestations of RA clinically, using the appropriate laboratory investigations. Anaemia was the commonest manifestation, occurring in (44.3%). Secondary Sjogren’s syndrome was found in (8.6%). Carpal tunnel syndrome in (6.08%), and Raynaud”s phenomena in (5.2%). These results were comparable with the results of studies from other countries. The prevalence of gastritis and PUD (8.5%) was less than reported (14-31%); this probably due to the routine use of anti-acids as prophylaxis. The SC nodules were found in only (3.4%): this was much less than reported (28%). Among the pulmonary manifestations, pulmonary fibrosis was found in (2.6%) of the patients, this was much less than reported (21%). No other pulmonary complications were found. None of the patients had cardiac, renal, eye disorders or evidence of cuteneous vasculitis

Nitric oxide (NO) is too short-lived to be measured in vivo, but its production can be estimated by measuring its stable oxidation products, nitrite/nitrate (NOx), or the intracellular second messenger cyclic guanosine monophosphate (cGMP), in serum. Its measurement is important for characterizing the regulatory roles of NO in various biological systems. The ability of the kidney to synthesise NO can be markedly influenced by disease states including chronic renal failure and diabetes. We evaluated serum NOx, and the biochemical indices of renal function, urea and creatinine, in 26 Libyan patients with end stage renal failure treated with hemodialysis in the dialysis unit at 2nd March Teaching Hospital, and another 26 healthy subjects, as a control. Interestingly, serum NOx level in the control subjects (18.7±3.7?mol/l) was significantly higher than that of the dialysis patients (10.7±1.56 ?mol/l), but had no significant correlation with urea and creatinine levels. In the hemodialysis patients, the level of NOx remained the same even after 3-4 hours of dialysis. However, serum urea (166±9.2mg/dl vs 85.2±6.6mg/dl) and creatinine (11.8±0.7mg/dl vs 5.5±0.3mg/dl) concentrations were significantly reduced (P<0.05). We conclude that further investigations of the biological properties of nitric oxide may lead to understanding, at least partly, the mechanism of the pathophysiology of chronic renal failure.

A sensitive spectrophotometric procedure was described for the determination of Nifedipine. The procedure is based on reduction of the nitro group, yielding free primary aromatic amine which could be diazotised and coupled to give red azo-dye with ? max at 510 nm and a violet with ? max at 555 nm with Bratton marschal and B- naphthol, respectively. The procedure was applied for determination of Nifedipine and Coracetene capsules with mean accuracies 100.9, 100.39 and 99.95, 100.5 respectively. The accuracy and precision of the suggested procedure were compared with the official method (B.P 1993) and the results obtained showed no significant difference between the two methods. Moreover the suggested method was more accurate, sensitive and precise compared to the official titrimetric procedure.

Background: The ovary is unique in the range of tumours that may arise from it, and the numbers of malignant tumours from other primary sites that can metastasize to it. Ovarian cancer is largely asymptornatic in its early stages and the majority of patients are presented with advanced intra-abdominal diseases. Objectives: To find out if trans-vaginal sonography can be helpful in differentiating benign from malignant ovarian tumours. Material and method: Prospective study carried out at Al-Jamahirya Teaching Hospital, Department of Gynaecology, Benghazi in Libya. In 162 women with ovarian mass in the age group between 16-67years. Laparatomy was performed and the mass was subjected to histopathological examination. The value of the following trans-vaginal ultrasound features were assessed: the tumour size, unilateral or bilateral, unilocular or multilocular, thin or thick wall, solid areas, papillary projections, pelvic nodules and ascitis. Results: We found that the size of the tumour is not helpful to differentiate benign from malignant ovarian lesions. Other ultrasound features seen in malignant ovarian masses are: multilocular (44.4%)of malignant and (29.9%) of benign masses; papillary projections were present (55.6%) of malignant and (22.9%) benign lesions, bilateral masses seen in (44%) malignant and (27.8%) benign masses, solid areas were found in (77.8%) of malignant and (18.8%) of benign tumours, pelvic nodules were present in (66.6%) of malignant and (0%) of benign masses, while ascitis was found in (66.7%).of malignant and (0.7%) of benign masses. Conclusion: Trans-vaginal scaning was helpful in differentiating between benign and malignant ovarian tumours. Ovarian malignancy should always be considered when the mass is bilateral, multilocular, with thick wall solid areas. When pelvic nodules or ascitis is present in association with a pelvic mass, the mass is almost always malignant. But there is no guarantee that masses not having these features are not malignant or will not undergo malignant changes if ignored.

Many systemic diseases are associated with ocular manifestations. Diabetic Retinopathy is the leading cause of new blindness in adults. Considerable progress has been made for the detection and treatment of diabetic eye disease, helping to lift the threat of blindness from people with diabetes. Ophthalmological examination is extremely important since timely treatment reduces serious vision loss by up to 95%. Thus medical practitioners must be well aware of the clinical features of diabetic ophthalmopathy and the best time to refer these patients to Ophthalmologists.
