Cell phones are commonly used in healthcare settings for rapid communication within hospitals. Concerns have been increased about the use of these devices in hospitals, as they can be used everywhere, even in toilets. Therefore, they can be vehicles for transmitting pathogens to patients. This study aimed to examine the presence of pathogenic bacteria on the surfaces of cell phones that are used frequently by preclinical medical students. This cross-sectional study identified both pathogenic and nonpathogenic bacteria on cell phones of 105 medical students at King Abdulaziz University, Jeddah, Saudi Arabia, using standard microbiological methods. Out of 105 cell phones screened, 101 (96.2%) were contaminated with bacteria. Coagulase-negative staphylococci were the most abundant isolates (68%). Seventeen (16.2%) cell phones were found to harbor Staphylococcus aureus. Gram-positive bacilli were isolated from 20 (19%) samples. Viridans streptococci and Pantoea species were also isolated but at lower levels. Our findings indicate that cell phones can act as reservoirs of both pathogenic and nonpathogenic organisms. Therefore, full guidelines about restricting the use of cell phones in clinical environments, hand hygiene, and frequent decontamination of mobile devices are recommended at an early stage in medical schools, to limit the risk of cross-contamination and healthcare-associated infections caused by cell phones.
Background/Aims:Gastroesophageal reflux disease (GERD) is a common condition that can lead to significant morbidity. Laryngopharyngeal reflux (LPR) is a distinct clinical entity that can occur simultaneously with GERD, necessitating additional treatment measures. The degree of overlap and clinical predictors of LPR among patients with GERD remains unknown. We aim to measure the prevalence of LPR in patients with GERD and identify clinical predictors.Patients and Methods:We performed a cross-sectional study involving patients with confirmed GERD according to the GERD questionnaire (GerdQ) using the reflux symptom index (RSI). Data on demographics, comorbidities, past and current medications, and GERD-related lifestyle measures were documented. The prevalence of LPR was calculated. Linear and logistic regression analyses were conducted to correlate GerdQ and RSI, and to identify clinical predictors of LPR, respectively.Results:A total of 80 patients with confirmed GERD were consecutively recruited and surveyed. Mean age was 43 (±16) and 60% were females. The majority of patients were Saudis (51%) and only 24% were smokers. The mean duration of GERD was 7 (±4.4) years and the average body mass index (BMI) was 36 ± 22. Sixty-six percent of the patients consumed coffee on regular basis. On simple and multiple linear regression analyses, a strong, positive correlation was observed between the GerdQ and RSI scores (coefficient = 1.13, 95%CI = 0.39–1.86), and ipratropium bromide inhaler was positively associated with RSI scores (coefficient = 13.12, 95%CI = 0.16–26.09). LPR was identified in 57 patients (71%). On simple and multiple logistic regression analyses, GerdQ scores (OR = 1.78, 95%CI = 1.13–2.80), BMI (OR = 1.07, 95%CI = 1.01–1.14), duration of GERD in years (OR = 1.42, 95%CI = 1.04–1.93), and the type of gender (OR = 49.67, 95%CI = 1.32–1870) appeared to increase the risk of LPR, whereas coffee consumption (OR = 0.0005, 95%CI = 1.82e–06, 0.13) appeared to be negatively associated with LPR.Conclusions:Contradictory to what is frequently reported, LPR commonly occurs and positively correlates with GERD. Several modifiable clinical predictors of LPR might exist, which highlight the importance of performing a complete clinical assessment of the patients with reflux symptoms.
Background: Glucose-6-Phosphate-Dehydrogenase (G6PD) deficiency is the most common enzyme deficiency globally and is more remarkable in certain parts of the world which had high malaria prevalence in the past. It is an X-linked genetically inherited disorder, where the first presentation can be neonatal jaundice. There are over 300 variants of this disorder based upon the genetics. Although the morbidity and mortality is not very high, the deficiency can be more appropriately managed by proper preventive methods which include screening and avoidance of trigger. Also prompt management of acute hemolysis can save a child from many complications. Methodology: we conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE from January 1987 to March 2017. The following search terms were used: G6PD deficiency, prevalence of G6PD, genetics of G6PD deficiency, management and diagnosis of G6PD Aim of the work: this study aimed to understand about the etiology, pathophysiology and study various lines of prevention and management of G6PD deficiency in pediatric age group. Conclusion: proper preventive and treatment methods can avoid negative effects on the child's quality of life and reduce morbidity and mortality, therefore the child's care takers must be well informed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
