Background: Atopic dermatitis, an eczematous dermatosis with a high incidence in cool climates and varies in frequency and clinical presentation among different age groups.Objective: To estimate the occurrence of atopic dermatitis among dermatological hospital patients in Benghazi.Methods: The percentage of atopic dermatitis among 3983 consecutive dermatological hospital patients was analyzed.Results: One hundred and fifty-seven patients (3.9%) were found to be affected with atopic dermatitis. Ninety-two (58.6%) were females with a female: male ratio was 1.4:1. In infantile and childhood groups a male: female ratio was 1.6:1, while in adult group female: male ratio was 4.9:1.Conclusions: Atopic dermatitis is not uncommon in Benghazi, where there is a moderate Mediterranean climate.

Blunt abdominal trauma is a leading cause of morbidity and mortality among all age groups. We retrospectively reviewed 255 laparotomies for abdominal injuries admitted to trauma department, Tripoli Central Hospital in a period of 2 years 1998-1999. The age group affected and the cause of trauma, our results match well with others, sex incidence in our study, 90% Males and only 10% Female, other studies 70% Males and 30% Females. The rate of negative laparotomies is 9%. The spleen was the most frequently injured organs 31.3% followed by liver injury 21.9%. About 84% of patients operated within 6 hours from the time injury. The comparison between the suspected injuries and finding at surgery showed that clinical decision alone is not very accurate and we need to make use of the available investigation. This study showed a lacking of good case note documentation, and the very limited use of available investigative procedures in the management of abdominal injuries.

Acute appendicitis is a very common surgical emergency and in spite of the advances in the diagnostic tools the diagnosis of acute appendicitis is based to a large extent on the clinical assessment. We studied the diagnosis of acute appendicitis in our set up. 1068 cases were retrospectively reviewed, the accuracy of our clinical diagnosis was about 86%, and the rate of normal appendicectomies was about 14%; the overall complication rate was about 11.8% and the mortality rate was 0.09%. The main complication was wound infection. Our drawbacks were mainly related to the lack of proper documentation about the location of the appendix and the reporting of mesenteric lymphadenitis and the very few appendices sent for histopathology.

The present study was performed on 21 pairs of cadaveric human calcaneal bones to determine the pattern of bone mineral density (BMD) and to correlate it with the biomechanical function of the calcaneal bone. The present results have demonstrated variations in the BMD in the defferent regions of the calcaneus. In lateral projection the anterosuperior region presented the highest BMD. The posterior region had the second highest BMD. The intermediate and anteroinferior regions presented the lowest BMD. The dorsal aspect of the whole calcaneus appeared denser than the planter aspect. In the dorsoplantar projection, the middle region had the highest BMD. The anterior region had the lowest BMD and the posterior region was nearly similar to that of the lateral projection. The lateral aspect of the whole calcaneus was denser than the medial aspect and the posterior aspect of the calcaneus was denser than the anterior aspect. The relationship between the bone density distribution of the calcaneal bones and their biomechanical function in the gait cycle is discussed.

Human cytomegalovirus (HCMV) is a major cause of morbidity and mortality in immunocompromised patients such as renal transplant recipient (RTr). In this study a total of 55 urine samples were collected from transplant patients, bone marrow recipients (BMr) and (RTr). Nucleic acid was extracted from the samples using the guanidinium isothiocyanate (GUSCN) method and the presence of CMV DNA was confirmed using the 724c P2 polymerase chain reaction (PCR). Specificity was confirmed by the detection of an alternative region of the viral genome in the same patients. Based on sequence variation of gB (UL55) and gH (UL75) genes, gene amplification and restriction enzyme analysis (REA) was used to differentiate between the CMV strains in the samples. The complete results of the gB typing showed that type 1 was most prevalent 10/55 (18%), type 2 found in 4 samples (7%), type 3 in 3 samples (5.5%) and type 4 in 2 samples (4%). No results was obtained for 36 samples (65.5%). The distribution of gH showed that type 1 was found in 6/39 (11%) and type 2 in 1039 (18°ol. No results obtained for 39 samples (71%). A comparison of gB and gH data were available for 16 samples. Of these. 5 samples (31.3%) were gB-1 gH-1 and 5 samples i31.3%) were gB-l/gH-2. whilst. 1 samples (6.2%) was gB-2 gH-2. one samples (6.2%) was gB-3 gH-1. 2 samples (12.5%o) were gB-3/gH-2 and 2 samples (12.5%) were gB-4 gH-2. no mixed genotypes were observed. In conclusion, all genotypes (gB and gH) have been found in transplant patient. Interestingly gB-1 and gH-2 are the most common types in transplant patients.

Recently, it has been proposed that stimulation of nitric oxide (no) by insulin-like growth factor-i (igf-i) in the kidney mediates the hyper-filtration, which follows a reduction in renal mass. The present study has been performed to establish wheter no can also influence the effect of igf-i on renal collagen protein. Male wistar rats were anaestheised with thiopentone (100 mg/kg), the kidneys were removed, sliced and incubated for 12 hours in physiological saline solution containing [14c] proline and ascorbic acid. Radiolabellled collagen was measured as the accumulation of new collagenase digestable protein (cdp). Slices were incubated with recombinant human igf-i (rhigf-i) 100nm in the presence and absence of either 100?m nitro-arginine methyl ester (l-name) or 10mm edta. Rhigf-i decreased the accumulation of new cdp 92179±229 to 1283±195 dpm/h/g, p<0.05), n=12) by 43%. L-name has no effect on basal cdp accumulation of cdp but prevented the decrease in the accumulation of cdp induced by igf-i (2166±185 to 1946±442 dpm/h/g, n=6). Edta alone produced a significant increase in the basal cdp accumulation (2184±432 to 3144±1088 dpm/h/g, p<0.05, n=8). In the presence of edta, the effect of igf-i on cdp was reversed from decrease to a significant increase (3144±1088 to 4250±1054 dpm/h/g) or 25%. Our results suggest that no may modulate the inhibitory effect of igf-i on collagen protein. The inhibitory effect of edta suggests the involvement of calcium-dependent constitutive form of no synthase. Edta, which also inhibits ion-dependent proteplytic enzyme activity, allowed the stimulatory effect of igf-i on renal collagen protein to be demonstrated. The possibility that no, derived from the constitutive form of no synthase, may inhibit matrix protein accumulation in the kidney has important implication to pathophysiology of renal disease.

Vitreous loss is a serious complication of cataract surgery. Following Vitreous loss it is common practice to perform a primary implantation of an anterior chamber lens(AC-lOL). We retrospectively analyzed 300 consecutive cases of cataract extraction performed at the great river eye hospital Benghazi with special attention to those patients in whom vitreous loss occurred & an ACILO was placed. There were 30 such cases. 19 cases with senile mature cataract 9 cases senile immature cataract, 2 cases traumatic cataract. The visual acuity of those patients seen post operatively are 6/60 and less. Complications that occurred are discussed. We are concerned that the complications associated with vitreous loss & with AC-IOL may be acting in concert to cause visually disabling.
