Prevalence of Gram-negative Bacterial Infections among Preterm Neonates in Tripoli-Libya

Preterm neonates are highly vulnerable and most susceptible to Infections. Gram-negative bacterial (GNB) infection is an increasing problem among hospitalized neonates. It is showing periodic and geographic variations in the distribution and antibiotics resistance which necessitate continuous surveillance. In present study surveillance of Gram-negative bacterial colonization and infection among preterm neonates was carried out between July, 2008 and January, 2009 at AL Jala Hospital of Obstetric and Gynecology, Tripoli. This study aimed to determine the prevalence of Gram negative infections among preterm neonates, correlate colonization with the onset of subsequent infection, and to determine the antibiotics susceptibility of Gram-negative isolates. Surveillance swabs from mouth, nose, rectum, axilla and umbilicus were collected from 112 preterm neonates twice at first week, the first swab was taken before the preterm receive any antibiotics, then once per week. Clinical samples from preterm neonates who developed infection were collected according to the site of suspected infection. Samples transport, isolation and identification of GNB were conducted according to standard microbiological methods. Infection is the cause of death in 25% of cases. 19.6% of neonates colonized at the first day, 63.2% at third day and 66.7% at the second week. 25 of 74 colonized neonates and one of 38 noncolonized neonates developed infection. Rectum was the commonest site of colonization. A. baumannii is a permanent colonizer, K. pneumoniae and E. coli are early colonizers and E. cloacae and Pseudomonas spp. are late colonizers. Isolates specially K. pneumoniae and E. coli showed high resistance to most used antibiotics mainly ampicillin and gentamicin. 26 (23%) neonates developed infection mainly caused by E. coli and K. pneumoniae. Only eight cases using microbiological culture proved infections. In conclusion Gram-negative infection could be a major cause of death among preterm neonates. Acquisition of GNB increased with hospitalization and it is an important step in developing infection. Preterm neonates were heavily colonized at 3rd day of hospitalization by most GNB. K. pneumoniae and E. coli were found to be the most resistant strain to antibiotics and were associated with high rate of infection. Rectum could be used as a surveillance site instead of the other sites.

Histological and Histochemical Study on the Effects of Malathion on the Liver of Adult Male Albino Rat and the Possible Protective Role of Atropine

يعتبر الملاثيون من المركبات الفوسفورية العضوية الأكثر شيوعا كمبيد حشري لآفات المحاصيل الزراعية و يستخدم أيضا في المنازل و الحدائق و المستشفيات و المشاتل و الصوبات, و يتيح هذا الانتشار الفرصة لتعرض الإنسان له بمختلف الطرق عن طريق البلع أو التنفس أو الجلد. ولقد وجد أن هناك علاقة بين انتشار و تأثير الملاثيون في الأعضاء المختلفة و طريقة إعطائه, حيث زادت تأثيراته عند إعطائه بالحقن عنه بالفم أو عن طريق الجلد. الهدف من البحث هو دراسة وتقييم تأثير الملاثيون تجريبيا على كبد ذكور الفئران البيضاءالبالغة من الناحية الهستولوجية والهستوكيميائية وكذلك دور الأتروبين كوسيلة وقائية وعلاجية لتلك التأثيرات. أجريت الدراسة على 32 من ذكور الفئران البيضاء البالغة يتراوح أوزانها ما بين 200-225 جرام وقد تم إتباع النظافة والعناية اللازمة للمحافظة عليها وقد تم وزن الفئران عند بداية التجربة وتسجيل الأوزان في جدول إحصائي كما تم تسجيل الحالة الصحية للفئران خلال التجربة وتم تقسيم الفئران إلى أربعة مجموعات. المجموعة الأولى (المجموعة الضابطة): تم إعطائهم الماء المقطر عن طريق الفم أو بالحقن. المجموعة الثانية (المعالجة بالملاثيون): تم إعطائهم الملاثيون (57%) من تحضير شركة النصر عن طريق الفم. المجموعة الثالثة (المعالجة بالاتروبين): تم إعطائهم الاتروبين بالحقن في العضل. المجموعة الرابعة (المعالجة بالاتروبين بعد وقف علاج الملاثيون): تم إعطائهم الملاثيون عن طريق الفم لمدة شهر ثم بعد ذلك تم حقنهم في العضل بالاتروبين لمدة شهر. .بعد انتهاء فترة العلاج تم وزن الفئران، ثم التضحية بها وتم استخراج الكبد لعمل قطاعات شمعية وقطاعات بواسطة الكريوستات لغرض الدراسة النسيجية والهستوكيميائية. لوحظ في قطاعات الكبد للفئران المعالجة بالملاثيون فقدان للترتيب الهيكلي للفصيصات الكبدية مع وجود تدمير لبعض خلايا الكبد وتضخم في بعضها الأخر الذي أظهر تراكمات من الدهون، وقد لوحظت تغيرات عديدة في أنويه الخلايا الكبدية وتشمل ضمور بعضها وتحلل بعضها. كما وجد احتقان وتمدد في مختلف الأوعية الدموية في الكبد مع تسلل ملحوظ لخلايا الدم وتدمر في عدة مناطق أخرى من الكبد. وقد أظهرت القطاعات الكبدية في الفئران بعد توقف المعالجة بالملاثيون تحسنا جزئيا مع استمرارية الاحتقان والتسلل الخلوي وقد كان ذلك أكثر سوءا من تلك الفئران المعالجة بالاتروبين بعد توقف فترة العلاج بالملاثيون من حيث تمدد واحتقان الأوعية الدموية والتسلل الخلوي حيث أصبحت تلك القطاعات مقاربة لقطاعات المجموعة الضابطة. أظهرت المجموعة المعالجة بالملاثيون زيادة ملحوظة في كمية الجليكوجين في سيتوبلازم الخلايا وانخفاض ملحوظ في تفاعل الأحماض النووية و الفوسفاتيز القلوي و السكينيك ديهيدروجنيز وقد زاد نشاط إنزيم الفوسفاتيز الحامضي. وقد لوحظ تحسن كامل في محتويات الجليكوجين و تفاعل الأحماض النووية ونشاط إنزيم الفوسفاتيز القلوي والسكينيك ديهيدروجنيزوانخفاض في نشاط إنزيم الفوسفاتيز الحامضي في الفئران المعالجة بالاتروبين بعد توقف فترة العلاج بالملاثيون مقارنة بالمجموعة التي توقف فيها العلاج بالملاثيون. أن زيادة استخدام المبيدات الكيميائية في العالم الحديث على نطاق واسع للأغراض المنزلية والزراعية أدى إلى الكثير من التركيز على احتمال تلوث بيئي خطير. والملاثيون من المبيدات الحشرية الضارة الواسعة الانتشار ولذا يجب أن تتخذ الاحتياطات المناسبة لتجنب التعرض للملاثيون أثناء وبعد عمليات الرش المختلفة ويجب أن يؤخذ في الاعتبار برامج التوعية العامة ضد الآثار السامة للمبيدات الحشرية ومحاولة تقييد استخدام الملاثيون لحماية البشر والبيئة من الخطر مع توفير كل ما يلزم من معدات الحماية للعاملين في عمليات الرش المختلفة. وأخيرا مما سبق تتضح الآثار المدمرة للملاثيون على الكبد والتي لا يمكن استردادها بالكامل بوقف التعرض للملاثيون وضرورة استخدام ترياق الاتروبين. لذا من المستحسن تقييد استخدامه لحماية البشر والبيئة أو محاولة استبداله بمواد بيولوجية أخرى.

Seroprevalence of Pertussis in School-entry Age Children in Libya, A Cross-sectional Study

Objective: In Libya, no pertussis booster doses are administered to children after 18 months of age. In light of evidence of waning of vaccine-induced immunity to pertussis, this study aimed to evaluate the waning of immunity in vaccinated school-entry age children, as measured by susceptibility to infection at population level. For this purpose, IgG and IgA levels were measured as markers of recent (infection in the last 6 months) and non-recent infections (infection in the last 12 months). Material and Methods: This was a cross sectional study undertaken in Tripoli, in February 2015. Children of school-entry age (> 5 to ≤ 7 years) were recruited on convenience basis at vaccination centers. Sera were tested for antibodies to pertussis. Results: Samples from791 children (421 males and 370 females, mean age 6.50 were tested). All of the participants had received 4 doses of Whole cell pertussis containing vaccine in the first 2 years of life. The prevalence of recent and non-recent pertussis infection were 4.8% and 2.5%, respectively. The proportion of children with undetectable level of IgG was 76.1%. Conclusion: The findings of this study showed significant circulation of Bordetella pertussis among vaccinated children by school-entry age. The circulation of B. pertussis in this population may be an indirect sign of waned immunity, which is simply corroborated by the absence of detectable antibodies in 76.1% of the children. arabic 14 English 76

Impact of Maternal Diabetes Mellitus on Early Morbidity and Mortality of Preterm Babies at Al Jala Maternity and Gynecology Hospital, Neonatal Intensive Care Unit (Tripoli, Libya)

ABSTRACT Studying burden of maternal diabetes mellitus on preterm babies is an important step to improve outcomes of these babies. The study was designed to compare morbidity and mortality in preterm babies (28-36 wks) born to `mothers with and without diabetes mellitus (DM). An analytical cross-sectional study was conducted at Al Jala Maternity Hospital, Neonatal Intensive Care Unit (NICU) department; all preterm babies with gestational age (GA) (28-36 wks) were enrolled in the study, from January 1st 2016 to December 31st 2016. The study sample was divided to two groups according to maternal health; preterm infant of diabetic mother (IDM) and preterm non-IDM. The information retrieved and analyzed were; sex, gestational age, birth weight, mode of delivery (MOD), Apgar score at 1st and 5th minute, hypoglycemia, respiratory illness, hyperbilirubinemia, sepsis, major congenital anomalies , length of stay (LOS), and neonatal death. Collected data coded and SPSS software was used for analysis. A total of 378 preterm babies were enrolled in the study period divided into: preterm IDM group 79(20.9%) babies and preterm non-IDM group 299(79.1%) babies. The preterm IDM group had significant high frequency of large for gestational age (LGA) and unexpectedly significantly low frequency in respiratory diseases (P= 0.047), perinatal asphyxia (P=0.021) and neonatal mortality (P=0.007); and no statistical significant difference in rate of hyperbilirubinemia (P= 0.145), congenital anomalies (P= 0.187) and sepsis (P= 0.468). Preterm babies born to diabetic mothers do not appear to be at an excess risk of mortality or early morbidity, except for birth weight for which diabetic mothers need more antenatal care. arabic 29 English 150

Risk calculation of developing type 2 diabetes in Libyan adults

The aim of this study was to identify nationals at risk of developing type 2 diabetes within the next 10 years in some areas across Tripoli Health Authority in Libya. In this questionnaire‐based survey, a total of 400 Libyan nationals of both genders were randomly selected from seven areas across the central area of Tripoli Health Authority (Soug El‐Juma, Zawet Dahmani, Al‐Furnaj, Ain Zara, Al‐Madena Centre, Al‐Dhahra Centre, and Noflean). All participants approached (400) completed the study and responded to the items of the survey. Based on a modified Finnish Type 2 Diabetes Risk Score test (FINDRISC), 129 (32.3%) were categorised as either at moderate or at high/very high risk of developing diabetes within the next 10 years of life. Among the 129 participants at risk, body mass index was >25 kg/m2 in 125 (96.9%) and waist circumferences were high (>88 cm for females;>102 cm for males) in almost 45% of the women and 22% of the men. We found that in the sample studied the risk of developing diabetes was clear, and there is no doubt that interventions to reduce such risk are a priority rather than a need. Diabetes has a great impact on the health of the nation and also on the future resources of the country in managing the disease and its complications; a health education/health campaign could be one good answer to tackle the problem. arabic 9 English 54

Prognostic indices for hospital mortality among Libyan diabetic patients

The pattern of diabetic deaths in the medical wards of Tripoli Medical Centre was retrospectively studied. During a three‐year period, 575 diabetic deaths occurred, accounting for 26.2% of all medical deaths. The mean age at death was 65.33±12.7 years. Cardiovascular disease (183 [31.8%]), cerebrovascular accidents (102 [17.7%]) and infection (83 [14.4%]) were the most common complications associated with diabetic deaths. Other causes were malignancy (10%), liver cirrhosis (5.6%), and acute diabetic complications (5%). Forty‐five (7.8%) deaths unaccountable for may be due to other unknown causes. Factors predictive of mortality, such as admission diagnosis of hyperosmolar non‐ketotic state, cerebrovascular disease, acute coronary syndromes or infection were associated with poor prognosis. Admission hyperglycaemia, old age, renal dysfunction and prior stroke were also associated with poor admission outcome. The excess mortality, mainly due to atherosclerotic complications, is potentially preventable through implementation of serious approaches to the management of cardiovascular risk factors. arabic 8 English 64

Evaluation of risk factors in acute myocardial infarction patients admitted to the coronary care unit, Tripoli Medical Centre, Libya

The aim of this study was to provide an overview of the risk factors for acute myocardial infarction in patients attending Tripoli Medical Centre, Libya. Records were reviewed for 622 patients with a mean age of 58.3 (SD 12.9) years. Diabetes mellitus (48.2%), hypertension (35.7%) and smoking (50.6%) were among the risk factors reported. There were 110 patients (17.7%) who died during hospitalization, mainly suffering cardiogenic shock (48.0%). The rate of use of thrombolytic therapy was low in patients who were female (40.4% versus 58.4% for males), older age (31.6% for those > 85 years versus 63.3% for patients < 55 years), diabetics (45.3% versus 62.0% for non-diabetic patients) and hypertensives (47.3% versus 57.8% for non-hypertensive patients). Prevention strategies should be implemented in order to improve the long-term prognosis and decrease overall morbidity and mortality from coronary artery disease in Libyan patients. arabic 20 English 112
