النزاهة من فن البديع المعنوي بين التعريف والتطبيق

The variety and difference in natural capabilities of a nation can be observed in their conversational skills. If the mental level of an individual has properly grown up, his power of expression, vocabulary and style of reasoning will be defiantly of high standard as compared to a common man. Similarly, when these skills get a literary shape it become more standardized. “Al Nazaha” is the art of the speech having similarity with satire (هجو )to a level but is different in many aspects with respect to its application, such as purification of plebian words )كالم سوقيانه, )reformative critical outlook and broad thinking etc. This article deals with the art of speech )النزاهة )its introduction and utilization in the Arabic and Islamic sources

Prevalence of Abnormal Aminoglycoside Trough Levels in Children With Clinically Suspected Gram Negative Infections at the Aga Khan University Hospital, Nairobi

Background: Aminoglycosides are commonly used in the treatment of severe gram-negative infections. Their use is associated with substantial risk of toxicity and hence need to monitor therapeutic drug levels. The prevalence of abnormal aminoglycoside trough levels in hospitalized children in our local setting has not been determined thus putting into question the cost benefits of providing therapeutic drug monitoring services in our resource poor settings. Objective: To determine the prevalence of abnormal aminoglycoside trough levels in children below the age of 12 years with clinically suspected gram negative infections at the Aga Khan University Hospital, Nairobi. The secondary objective was to determine if glomerular filtration rate (GFR) estimation using Schwartz formula correlates with drug trough levels in children on aminoglycoside therapy. Methods: Children aged 1 day up to 12 years started on aminoglycoside therapy with either gentamicin or amikacin were identified in this hospital based cross-sectional survey that was undertaken at the Aga Khan University Hospital, Nairobi over a period of six months. Aminoglycoside drug trough levels and serum creatinine measurements were done in 81 patients at 24hours after initiation of aminoglycoside therapy. GFR was calculated using Schwartz formula for all the serum creatinine values obtained. Data analysis: Data accrued were analysed using Stata Data Analysis and Statistical software. The prevalence of abnormal aminoglycoside trough levels was calculated. The Pearson correlation coefficient was calculated between the drug trough levels and estimated GFR. The prevalence, sensitivity, specificity, positive and vi negative predictive values as well as likelihood ratios, and hence accuracy of estimated GFR in predicting for abnormal aminoglycoside trough levels was also calculated. The area under the receiver operating characteristic (ROC) curve was also determined. Results: A total of eighty one participants were recruited into this study with a median age of three days, 48.2% of whom were males and 51.8% female. The prevalence of abnormal aminoglycoside trough levels in children below the age of 12 years with clinically suspected gram negative infections admitted at the Aga Khan University Hospital, Nairobi was 4.9% (95% CI 1.4% to 12.2%). There were no reported adverse outcomes in any of the children with abnormal drug trough levels upon follow-up. The strength of the association between aminoglycoside trough levels and glomerular filtration rate was found to be weak with Pearson correlation co-efficient of -0.342. The sensitivity and specificity of estimated GFR in predicting for abnormal aminoglycoside trough levels was 25.0% and 98.7% respectively. The
