RESUMO
INTRODUCTION: Gram-negative bacteria (GNB) have become prominent across healthcare and community settings due to factors including lack of effective infection control and prevention (ICP) and antimicrobial stewardship programs (ASPs), GNB developing antimicrobial resistance (AMR), and difficulty treating infections. This review summarizes available literature on healthcare-associated infections (HAIs) in Middle Eastern pediatric patients. METHODS: Literature searches were performed with PubMed and Embase databases. Articles not reporting data on GNB, HAIs, pediatric patients, and countries of interest were excluded. RESULTS: The searches resulted in 220 publications, of which 49 met the inclusion criteria and 1 additional study was identified manually. Among 19 studies across Egypt reporting GNB prevalence among pediatric patients, Klebsiella species/K. pneumoniae and Escherichia coli were typically the most common GNB infections; among studies reporting carbapenem resistance and multidrug resistance (MDR), rates reached 86% and 100%, respectively. Similarly, in Saudi Arabia, Klebsiella spp./K. pneumoniae and E. coli were the GNB most consistently associated with infections, and carbapenem resistance (up to 100%) and MDR (up to 75%) were frequently observed. In other Gulf Cooperation Council countries, including Kuwait, Oman, and Qatar, carbapenem resistance and MDR were also commonly reported. In Jordan and Lebanon, E. coli and Klebsiella spp./K. pneumoniae were the most common GNB isolates, and AMR rates reached 100%. DISCUSSION: This review indicated the prevalence of GNB-causing HAIs among pediatric patients in Middle Eastern countries, with studies varying in reporting GNB and AMR. Most publications reported antimicrobial susceptibility of isolated GNB strains, with high prevalence of extended-spectrum beta-lactamase-producing K. pneumoniae and E. coli isolates. A review of ASPs highlighted the lack of data available in the region. CONCLUSIONS: Enhanced implementation of ICP, ASPs, and AMR surveillance is necessary to better understand the widespread burden of antimicrobial-resistant GNB and to better manage GNB-associated HAIs across Middle Eastern countries.
RESUMO
Objectives. This study was carried out to delineate the patients' characteristics and the imaging findings and their relation to some biochemical markers of 31 critically ill patients with MIS-C. Design. A retrospective cross-sectional study including all critically ill MIS-C patients admitted to the PICU from June 23rd to July 22nd, 2020. Results. Eighteen males and 13 females, with a median age of 9 years (interquartile range 6-11) presented mainly with fever (100%) and hypotension (100%). Abnormalities in the chest computed tomography were detected in 22 cases (71%). Consolidation and architecture distortion were detected in 58.1% of patients; bilateral lesions and lower lobe infiltrates, each, was evident in 64.5% of patients, while the peripheral distribution of lesions was seen in 71% of the cases. Pleural thickening and effusion, each, was found in 51.6% of the patients. In this small case series, the presence of high ferritin was significantly associated with the bilaterality of the lesions. Elevated C-reactive protein was associated with the peripheral distribution of the lesions. Thrombocytopenia and hypoalbuminemia were significantly correlated with the CT disease stage and CT severity score respectively. Conclusions. Although a few children in this group of MIS-C patients presented with respiratory manifestations, yet, most of them demonstrated significant radiological lung involvement, which necessitates a longer-term follow-up.
RESUMO
The aim of this study was to isolate some soil bacteria strain that produced α-amylase and subsequent extraction and purification. One hundred soil samples were collected from different geographical areas in Khartoum State such as north Omdurman, Toti Island, and Soba. Samples were analyzed for starch hydrolyzing bacteria. Among several bacteria isolated, Bacillus cereus and Bacillus licheniformis were identified as active α-amylase producers. Both bacteria showed a large zone of clearance of 20 mm when grown on starch-agar plates. The identity was conducted using biochemical characterization and confirmed by sequencing their 16S-rDNA. The constitutive nature of amylase was proved by amplification of the amylase gene from the genome of B. licheniformis. The α-amylase activity from the spent medium of B. cereus and B. licheniformis was optimized at pH 8.0 and temperature of 45°C and 65°C, respectively. The α-amylase produced by both bacteria is alkalophilic and thermophilic. The experiments confirmed that B. licheniformis can be a good source of amylase for industrial applications in Sudan.
RESUMO
The global concern of increasing number of children presenting with multisystem inflammatory syndrome in children (MIS-C) related to the coronavirus disease (COVID-19) has escalated the need for a case-oriented clinical approach that provides timely diagnosis and management. The aim of this study is to share our experience in managing 64 MIS-C patients of North African ethnicity guided by a risk-based algorithm. Sixty-four patients met the inclusion criteria, 19 (30%) patients were categorized as mild and moderate risk groups and cared for in an isolation ward and 45 patients who belonged to the high-risk group (70%) were admitted to the pediatric intensive care unit (PICU). Positive laboratory evidence of COVID-19 was found in 62 patients. Fever and dysfunction in 2 or more organs were confirmed in all cases (100%). Fifty patients (78%) presented with gastrointestinal symptoms, meanwhile only 10 patients (16%) had respiratory manifestations. Cardiac involvement was reported in 55 (86%) cases; hypotension and shock were found in 45 patients (70%) therein circulatory support and mechanical ventilations were needed for 45 and 13 patients respectively. Intravenous immunoglobulins (IVIG) were used for all cases and methylprednisolone was used in 60 patients (94%). Fifty-eight (91%) patients were discharged home after an average of 9 days of hospitalization. The mortality rate was 9% (6 patients). Conclusion. A single Egyptian center experience in the management of MIS-C patients guided by a proposed bed side algorithm is described. The algorithm proved to be a helpful tool for first-line responders, and helped initiate early treatment with IVIG.
RESUMO
INTRODUCTION: Job satisfaction is an important factor influencing the health of workers and is directly related to quality of care. OBJECTIVES: To assess the level of job satisfaction and factors contributing to dissatisfaction of Saudi physicians in primary health care centers in Jeddah. Methods All Saudi physicians working in primary health care centers in a city in the Western region, KSA, were included in this web-based survey using the "Job Satisfaction Survey" questionnaire adopted by Paul E. Spector (1994). In addition, socio-demographic data (age, sex, marital status, work facilities, qualification, work experience and income) were collected (response rate 83% ). RESULTS: 63% of the physicians are satisfied about the nature of work in the primary health care centers, while 25.2% were satisfied about the payment. A large proportion of respondents were dissatisfied about the contingent rewards and fringe benefits (83.2%, 76.5%respectively). None of the specialists were satisfied about the work compared to 10.6% of the general practitioners. CONCLUSION: Slightly less than half of the physicians are satisfied. Financial incentives (contingent rewards and fringe benefits) impose a negative impact on job satisfaction for primary care physicians. On the other side, the nature of work has had the most positive impact on job satisfaction. Specialists were found to have less satisfaction. Investing in the physicians' satisfaction about the nature of work in the primary healthcare facilities to create a sense of ownership that would be reflected on the quality of patient care is required. There is a need to conduct further studies on the fiscal privileges that lead to job satisfaction among physicians.
RESUMO
OBJECTIVES: Since March 2020, a rapid increase has been observed in the prevalence of the COVID-19 pandemic, which has essentially resulted from increased disease transmission and intensified testing and reporting. The international guidelines for the prevention and treatment of the COVID-19 pandemic have been frequently updated. Such guidelines assist the governmental regulatory bodies in taking optimal measures and safeguarding their citizens against the pandemic. We conducted a short survey with a Saudi cohort to understand the awareness about COVID-19 and estimate the responses for mitigation strategies. METHODS: An electronic survey was conducted, and the first 388 responses were analysed for publishing an initial report. The questionnaire comprised 27 items and was divided into three sections, namely demographic, awareness, and response to mitigation strategies and participants' self-perceived behaviours regarding COVID-19. The perceptions of the participants were compared with their responses to mitigation measures. RESULTS: In our study, 89.7% understood the meaning of pandemic, while 82.2% correctly identified that the elderly belonged to a high-risk group for the COVID-19 infection. As many as 96.1% agreed that staying at home was one of the mitigation strategies. Nearly 35% preferred self-medication. Higher educational level (OR: 2.09, 95% CI: 1.02-4.29) and longer working hours were found to be significantly associated with a positive response to mitigation measures with p < 0.04 and p < 0.02, respectively. CONCLUSIONS: We report better understanding and appropriate response to mitigation measures towards the COVID-19 pandemic among the general population in KSA. Nevertheless, the tendency towards self-medication was reported by one-third of the responders.
RESUMO
INTRODUCTION: The objective was to determine the frequency of gastroesophageal reflux (GER) in mechanically ventilated pediatric patients and its role as a risk factor for ventilator-associated pneumonia (VAP), which may be enhanced among those patients. METHODS: The study is a prospective cohort study of mechanically ventilated pediatric patients in the pediatric intensive care unit (PICU) of Ain Shams University Children's Hospital. It was conducted in 24 mechanically ventilated patients (16 of them developed VAP and 8 did not, with mean age of 16.6 +/- 20.5 and 18.6 +/- 22.4 months respectively). Esophageal 24-hour pH-metry beside clinical and laboratory evaluation of their underlying problem and severity of their condition were carried out. RESULTS: All VAP patients had GER (50% alkaline reflux, 12.5% acidic reflux and 37.5% combined reflux) compared to 75% of non-VAP ones (100% alkaline reflux). The mean total reflux time was significantly longer among VAP (50 minutes) versus non-VAP (3 minutes) patients. There was significant increase in acidic reflux parameters among non-survivors versus survivors (P < 0.001). For VAP mortality, total acidic reflux at a cut-off value of 28.6 minutes is found to be a mortality predictor with a sensitivity of 100% and a specificity of 100%. CONCLUSIONS: GER is a constant incident in mechanically ventilated pediatric patients, with alkaline reflux being more common than acidic reflux. Both acidic and alkaline refluxes were found to be associated with the development of VAP and total reflux time was found to be a reliable predictor of VAP. Moreover, acidic reflux was found to be more related to mortality than alkaline reflux.

BACKGROUND: Hospital-acquired (nosocomial) infection is a common serious health problem worldwide, especially in pediatric intensive care units and is associated with high mortality and morbidity, prolonged hospital stays and high cost. AIM: To determine the types of organisms involved in hospital-acquired an infection in two pediatric intensive care units during the one-year study and its anti-microbial susceptibility. MATERIAL AND METHODS: This study was carried out in the pediatric intensive care units (PICU) of Ain Shams & Cairo Universities, where 86 pediatric patients were recruited. Their age ranged from 1 month to 156 months with mean 20.7 ± 25.8 months. Male to female ratio was 37:29. Four samples were collected from each child for culture and sensitivity: blood, endotracheal aspirate, urine and skin swab. RESULTS: The most common microorganism was staphylococcus while Gram-negative bacteria were the commonest group. Amikacin and imipenem are the most sensitive antibiotics. Risk estimate for different risk factors among studied patients revealed no significance. CONCLUSION: Staphylococcus was the commonest micro-organism while Gram-negative infections were the commonest group among PICU with a predominance of Acinetobacter and Klebsiella. Respiratory infections were the most common, followed by blood-borne infection. Risk factors for mortality were not significant.
RESUMO
Disorders of sex development (DSD) are conditions with an abnormal development of chromosomal, gonadal, or anatomical sex. Sex chromosome DSD involve conditions associated with either numerical or structural abnormalities of the sex chromosomes. This study included patients comprising a wide spectrum of presenting features suggestive of DSD and aimed at studying the frequency of sex chromosome abnormalities among 108 Egyptian DSD patients who presented to the Clinical Genetics and Endocrinology Clinics, National Research Centre (NRC) over the 2-year period of 2013 and 2014. The age of the studied patients ranged from 2 months to 39 years. The patients exhibited various presentations, including ambiguous genitalia, undescended testis, hypogonadism, short stature with Turner manifestations, primary or secondary amenorrhea, primary infertility, edema of the dorsum of the hands and feet, and dysmorphic features. The patients were subjected to detailed clinical examination, pubertal staging, and cytogenetic analysis. Our study reported a wide karyotypic diversity and a high frequency of sex chromosome DSD, reaching 44.44% (48/108). In conclusion, we showed a high incidence of sex chromosome DSD among Egyptian DSD patients with wide karyotype/phenotype diversity. The most frequent sex chromosome DSD detected among patients of the present study was Turner syndrome and variants (52.08%; 25/48) followed by Klinefelter syndrome and variants (43.75%; 21/48). Further long term studies are necessary for accurate detection of frequencies of different types of sex chromosomal anomalies and associated phenotypes.
RESUMO
OBJECTIVE: Chronic hypoxia has an evident effect on cochlear function and hearing sensitivity. Otoacoustic emissions' testing is efficient in detecting subtle cochlear dysfunction. This cross sectional study was designed to assess the cochlear function in children with chronic lung diseases who were exposed to prolonged hypoxia and prolonged use of ototoxic drugs (as aminoglycosides) using basic audiological evaluation and transient evoked otoacoustic emissions testing. METHODS: The study was carried out on 30 Egyptian children with chronic lung disease recruited from the Pediatric Chest Clinic, Children's hospital, Ain Shams University. Twenty normal children were included as control. RESULTS: Six patients (20%) showed abnormal otoacoustic emissions. A significant effect of hypoxia on otoacoustic emissions findings was found (P<0.05). However, there was no significant effect of inhaled aminoglycosides on auditory functions whether pure tone audiometry, speech audiometry and transient evoked otoacoustic emissions testing. CONCLUSIONS: Children with chronic lung diseases are liable to cochlear dysfunction due to prolonged hypoxia. Inhaled aminoglycosides in chronic lung diseases is relatively safe on auditory functions.
