Bulgular: 791 çocuktan (421 erkek, 370 kız, ortalama yaş 6.5) alınan örnekler test edildi. Tüm çocuklar hayatlarının ilk iki yılında 4 doz tam hücreli boğmaca aşısı ile aşılanmıştı. Yakın zamanda gerçekleşen ve gerçekleşmeyen boğmaca enfeksiyonu sıklığı sırasıyla% 4.8 ve% 2.5 idi. Çocukların% 76.1’i tespit edilemeyecek düzeyde IgG’ye sahipti. Sonuç: Çalışma boğmaca enfeksiyonun okula başlayan çocuklar arasında sık olarak geçirildiğini göstermiştir. Bu artış, okula başlama yaşındaki çocukların% 76.1’inde serumda boğmacaya karşı antikor düzeyinin tespit edilemeyecek düzeyde olmasının dolaylı bir sonucu olması ile açıklanmıştır. arabic 26 English 62

Acinetobacter baumannii is an opportunistic pathogen causing various nosocomial infections. The aim of this study was to characterize the molecular support of carbapenem-resistant A. baumannii clinical isolates recovered from four hospitals in Tripoli, Libya. Bacterial isolates were identified and antibiotic susceptibility testing was per-formed using automated system. Carbapenem resistance determinants were studied phenotypically using two dif-ferent techniques: E-test; chromogenic culture media. Polymerase chain reaction (PCR) amplification was used to determine the presence of bla OXA23 and blaOXA51 genes among isolates. A total of 119 isolates were characterized, overall the resistance prevalence was extremely high for aminoglycosides (79-96.6%), fluoroquinolones (94-96%), cephalosporins (96.6-100%) and carbapenemes (93.2-100%), all isolates were susceptible to colistin. In addition, 97.5% of isolates were identified as multidrug resistance (MDR). Varying degree of phenotypic detection of car-bapenemes was determined; highest levels of carbapenemes were detected using chromogenic media (76.5%) com-pared with E-test (45.4 %). The carbapenem resistance-encoding genes detected were blaOXA23 (84%) and blaOXA51 (73.1%); the highest occurrence of blaOXA23 was demonstrated in Tripoli’s Central Hospital (5/5; 100%) then in Tripoli Medical Center (44/51; 86.27%). The co-occurrence of these genes was demonstrated in (75/119; 63%) showing dissemination of carbapenemes resistance MDR A. baumannii in hospitals. This study shows that the high prevalence of OXA-23 contribute to antibiotic resistance in … arabic 14 English 113

Takayasu’s arteritis (TA) is a large‑vessel vasculitis that involves the aorta and its major branches. Renal arteries are frequently involved, usually with renovascular hypertension. The prevalence of TA in Arabs is low. A study of the epidemiological and clinical features of TA in Arabs included 197 identified patients between 1995 and 2012 and none of them was Libyan. We report a 61‑year‑old Libyan woman in whom TA manifested with hypokalemia and arterial hypertension. Previous ultrasound showed renal size asymmetry raised the possibility of renal artery stenosis. The diagnosis of TA was confirmed by magnetic resonance angiography, which showed a thickened abdominal aortic wall, occlusions of the left renal artery and left common iliac artery, stenosis of the right common iliac artery, and stenosis of both subclavian arteries. TA is rarely encountered in Arabs. However, the disease must be considered in patients who present with renovascular hypertension, in a context of other autoimmune disorders. arabic 6 English 33
