School Screening for Scoliosis among Male Adolescents in Abha City, Southwestern Saudi Arabia

Aim: To study the prevalence of scoliosis and its associated factors among male adolescents in Abha city intermediate and secondary schools, Aseer Region, Southwestern Saudi Arabia. Methods: Through a cross-sectional study, students were interviewed about personal and demographic data, method of back-bag carriage, and regular practice of any physical exercise. Body mass index (BMI) was measured and student’s bag weight/BMI ratio (%) was computed. Screening for scoliosis was performed using inspection of the vertebral column and Adam’s Forward Bending Test (FBT). Using scolimeter a reading equal or exceed 5 degrees was considered positive. Results: Out of 417 screened adolescents, 90 students were positive giving a prevalence rate of scoliosis of 19.1% (95% CI: 15.7- 23.0). Using multivariable logistic regression analysis, the probability of positive scoliosis was significantly higher in secondary school (aOR=2.304. 95% CI: 1.447-3.676) and obese and overweight (aOR=2.433. 95% CI: 1.565-3.787) adolescents. On the other hand, regular practicing of physical exercises was significantly negatively associated with scoliosis (aOR=0.469, 95% CI: -316-0.695). Conclusion: The present study identified scoliosis as a substantial problem among adolescents. School health authorities need to foster a screening program for scoliosis, particularly among secondary school adolescents. School health promotion programs should address overweight and promote physical exercise to deal with this problem.

Prevalence, determinants and impacts of khat chewing among professional drivers in Southwestern Saudi Arabia

The objective of this study was to assess the prevalence and determinants of khat chewing, and explore its social, economic and work impacts and examine its relation with road traffic accidents [RTA] among professional drivers in Jazan region, Saudi Arabia. A cross-sectional study was conducted on 215 drivers recruited from transport stations in Jazan region by random cluster sampling. An interview questionnaire was utilized for data collection, and 47.4% of drivers were currently khat chewers. Using a logistic regression, the independent predictors of khat chewing were being a citizen of Saudi Arabia, divorced or widowed, working for less than 4 hours/day, and a non-seatbelt user. Khat chewing was significantly associated with shorter working hours; higher average number of significant RTA, and higher frequency of traffic violation. In conclusion, khat chewing habit affected almost half of the professional drivers in Jazan area. Moreover, khat chewing was associated with impaired working ability and productivity, family conflicts, and violation of traffic rules

Mobile Phone Use and Risk of Adverse Health Impacts among Medical Students in Jeddah, Saudi Arabia.

Background: Internationally, there is growing concern about the adverse health effects of mobile phone use by young people. Aim: To determine the pattern of mobile phone use among medical students and determine the potential association between degree of use and self-reported health impacts. Methods: A cross-sectional study was carried out on 472 medical students in King Abdulaziz University. Self-administered specially designed questionnaire was used to collect data regarding the following: Socio-demographic characteristics, pattern of phone use and self-reported health complaints. Results: The students’ median duration of mobile phone use was 330 min/day and was significantly higher in females (P= 0.04). A positive significant correlation was observed between the health complaints score and the average daily duration of use (r =0.139, P=0.002). Adjusted multiple logistic regression analysis revealed that heavy mobile use was significantly associated with self-reported sleep disturbances, headache (AOR=4.76), fatigue (AOR=4.67), depression (AOR=2.63), nervousness (AOR=1.64), musculoskeletal pain (AOR=2.14) and visual problems (AOR=2.40). Conclusion: mobile phone use occupies a significant part in the daily life of medical students. The heavy use of mobile phone in calling and non-calling activities was associated with a high level of subjective health complaints with dose dependent pattern. After controlling for other important predictors, heavy mobile use was associated with sleep disturbances, headache, depression, nervousness, eye and musculoskeletal problems. Excessive use of mobile phones should be avoided and social awareness increased through health education activities. In addition, employing a speaker-phone device for longer daily use and recommended parental procedures are taken to prevent young people being woken by their mobile phones.

Impacts of nurses' circadian rhythm sleep disorders, fatigue, and depression on medication administration errors

The safety and quality of the administration of medications by nurses raise the opportunity to study risk factors such as circadian rhythm sleep disorders, fatigue, and depression. This study was conducted to explore the extent of nurses' circadian rhythm sleep disorders, fatigue, and depression and their impact on medication administration errors. Both approval from the hospital ethics committee and formal patient consent were obtained. A descriptive cross sectional study was conducted using a demographic data sheet, a depression scale [CES-D], a modified fatigue severity scale, a medication errors observation sheet and an AASM two week sleep diary. The average number of medication errors per nurse per shift was 1.40 +/- 2. [Wrong time [and] wrong rate] were the most frequent medication errors [23.1% each]. About half [51.9%] of the nurses reported deficient sleep hours. Medication errors were negatively correlated with average working hours and positively correlated with depression score; errors peaked with irregular shift work patterns and irregular night sleep patterns in nurses with more than 4 night shifts in the preceding 2 weeks. Fatigue was significantly correlated with total depression score and significantly associated with deficient sleep hours. Additionally, the depression score was significantly affected by irregular sleep patterns. There were significant relationships between sleep medication intake and medication errors, depression, and fatigue. Linear regression analysis demonstrated that the independent predictors of medication errors were the number of patients under the nurses' direct care and the depression score of the nurses. Medication administration errors, fatigue and depression were all significantly affected by circadian sleep disorders. An administration's control of work flow to provide convenient sleep hours will help in improving sleep circadian rhythms and consequently minimize these problems

Helicobacter pylori cagA Gene in Egyptian sewage workers

A comparative cross-sectional study was conducted on 60 sewage workers and 30 matched unexposed referents from Mansoura city; Egypt; to estimate the prevalence and risk factors of Helicobacter pylori (H. pylori). Stool culture and detection of H. pylori antigen were done. In addition; the polymerase chain reaction (PCR) amplification of cytotoxin-associated gene A (cagA) gene in H. pylori in stool samples was carried out. The prevalence of H. pylori in sewage workers was 56.7% compared to 16.7% in the comparison group with a highly statistically significant difference between both groups. H. pylori cagA gene was present in 64.7% of H. pylori-infected sewage workers compared with 40% of controls. cagA gene was associated with more dyspeptic symptoms (77.3%) in infected workers compared to those of noninfected ones (33.3%) (P = .041). The risk of H. pylori was significantly higher among workers with poor compliance with personal protective equipment (PPE) (OR = 3.00); with duration of work 20 years (OR = 4.71); older than 45 years (OR = 4.27); and of low education level (OR = 11.2). We concluded that H. pylori infection and heartburn with or without epigastric pain are significant health problems in the studied sewage workers. Low education and poor compliance with PPE were the only predictors of H. pylori infection in sewage workers

Dose monitoring of health care workers occupationally exposed to ionizing radiation in Mansoura university hospitals

This study aims at evaluating the efficacy of radiation safety in Mansoura University Hospitals [MUHs] and to establish practical dose constraint [DC] for medical application. The study has been conducted upon health care workers [HCWs] occupationally exposed to ionizing radiation in various diagnostic and therapeutic activities in six health premises of MUHs. Four medical applications [radiotherapy, nuclear medicine, general radiology and interventional radiology] and five specialties [medical doctors, physicists, technicians, nurses and non-classified personals] were accounted. Doses were measured on a quarterly basis using thermoluniscent dosimeters [TLD-badges], while pocket dosimeters were used whenever TLD was not available. The annual doses were collected to build up a data base for years 1994-2005. The results show that TLD-badges were used in best situation in Oncology and Nuclear Medicine Dept. to cover less than one third of the exposed HCWs. The occupational doses showed a highly significant difference [p<0.0001] depending on the field of medical application. It is found that HCWs in radiotherapy were exposed to an average annual dose of 1.36 +/- 0.61mSv/y. For interventional radiology, the mean annual dose was found 2.25 +/- 2.47mSv/y unlike that of general radiology 1.07 +/- 0.65mSv/y. The largest sources of occupational exposure came from fluoroscopic radiology .equipments [1.76 +/- 0.92mS/y] followed by Cobalt-60 teletherapy machine [1.12 +/- 0.72mS/y]. The study showed that about 90% of HCWs received doses less than 2mSv/y and only 1.39% reported doses 5mSv or above. Dose constraint level can be set at 2mSv/y in premises of MUHs that may be considered achievable ceiling value referring to acceptably applied practices rather than optimized ones
