This study showed that the metabolism of amino acids was useful in differentiating between the species of Gram-positive anaerobic cocci (GPAC). The best results were obtained from those whose taxonomic positions or biochemical reactions were in doubt. These include Peptococcus ( Pc.) asaccharolyticus, Pc. aerogenes,, Pc. magnus, Pc. anaerobius, Pc. variabilis, Pc. niger and Peptostreptococcus (Pst. micros. For these species which are easily recognized by carbohydrate fermentation amino acid utilization was less discriminatory. It should be noted, however, that the most frequently isolated GPAC from clinical materials are those which have a high capacity to utilize amino acids. This study has revealed that the carbohydrate fermenters are less commonly encountered in clinical specimens. This indicates that the species which are more active against amino-acids are more commonly pathogenic, and this phenomenon should therefore be exploited to identify and classify the GPAC.

A total of 489 pregnant women attended gynecologic and obstructive Department, Obari Hospital (during the period of middle of November 2007 to end of January 2008) for routine clinical examination. Among 489, 51 (10.42 %) were clinically diagnosed as having vaginitis with vaginal discharge and their vaginal swabs were screened for Trichomonas vaginalis using direct wet-mount microscopy. Only nine samples (1.84 %) were found positive for T. vaginalis. All these patients complained of vaginal discharge, burning, vulvar pruritis and showed a heavy infection of T. vaginalis (3 to 4 parasites per 40 X field).

Acute Appendicitis represents the most frequent cause of surgical acute abdomen in emergency unit. The presentation is not always typical and late interventions for complicated appendicitis are still very high. Diagnostic adjuncts usually provide the additional information required to make a confident diagnosis. Aim of the study was to access prospectively the role of ultrasound in diagnosis of acute appendicitis. 100 patients were prospectively included in the study conducted at Misurata Teaching Hospital during 007. Patients were admitted to surgical department with suspicion of acute appendicitis, and then evaluated clinically with laboratory tests and ultrasound. 63% were males and 39% were females, 39% of them were between 11 and 20 years old. Acute appendicitis was diagnosed sonographically in 91. A total of 89 appendectomies were performed over this time period and in 86 of them the diagnosis was confirmed histologically. The false negative rate of ultrasound was 11.1%. Overall, patients who had preoperative imaging and diagnosed as acute appendicitis showed a low negative appendectomy rate of 3.4%. Ultrasound had a sensitivity of 94.5% and specificity 88.9%. Abdominal ultrasound for diagnosis and decision-making in acute appendicitis is useful and associated with a low negative appendectomy rate.

Aim: To identify and analyze the clinical presentation, management and outcome of patients with acute bowel obstruction along with the etiology of obstruction and the incidence and causes of bowel ischemia, and resection.Methods: This is a retrospective observational study of all adult patients admitted with intestinal obstruction to the surgical department in Misurata central hospital in the period of one year, between March 2007 and February 2008.Results: Of the 54 consecutive patients included in the study, the clinical presentations were abdominal pain, abdominal distension, vomiting, constipation and obstipation. Adhesions (50%), obstructed hernias (37%), and large bowel cancer (9%) were the most frequent causes of obstruction. Bowel resection was performed in 15 cases, 5 of them to resect large bowel cancer and 10 of them because of bowel gangrene due to strangulated hernias, adhesions, volvulus and mesenteric embolism.Conclusion: Close and careful clinical evaluation along with proper investigations is essential for decision of management of patients with acute bowel obstruction to avoid serious complications.
