Introduction: Chronic Mechanical Low Back Dysfunction (CMLBD) is the most common problem of the working-age population in modern industrial society; it causes a substantial economic burden due to the wide use of medical services and absence from work. Aim of work: To investigate the effect of positional release technique on patients with chronic mechanical low back pain. Materials and Methods: Thirty two patients from both sexes were diagnosed with CMLBP, aged 20 to 45 years and were divided randomly into two equal groups; sixteen patients each; group A (control group) received therapeutic exercises that include ( Stretch and Strength exercises for back and abdominal muscles). Group B (experimental group) received therapeutic exercises with positional release technique; treatment was applied 3 days/week for 4 weeks. Pain was measured by Visual Analogue Scale, Lumbar range of motion was measured by Inclinometer and Functional disability was measured by Oswestry disability scale. Measurements were taken at two intervals pre-treatment and post-treatment. Results: Data obtained was analyzed via paired and unpaired t-Test. There were statistical differences between the 2 groups, where the experimental group showed greater improvement than control group. Conclusion: Positional release technique is considered as an effective treatment for reducing pain, functional disability and increasing lumbar range of motion in individuals with chronic mechanical low back pain.

Introduction: Exposure to cyanide is encountered in many industries as in Case Hardening and Electroplating. Chronic exposure to cyanide is associated with some health effects including its effect on thyroid gland. Aim of work: To study the health effects due to chronic occupational exposure to cyanide with special emphasis on the thyroid gland. Materials and Methods: This study was conducted on 56 workers exposed to cyanide in case hardening and electroplating industry. Their age ranged between 36 and 59 years with a mean of 46.96 ± 5.51 years. They are exposed to cyanide from 4 to 31 years with a mean of 19.86 ± 8.53 years. They were compared with 60 workers not exposed to cyanide as a control group, Their age ranged between (30-60) years with a mean of 45.76 and S.D. ±11.81. Hydrogen cyanide was measured in air of workplace environment. Serum thiocyanate serum and thyroid hormones (T3, T4, and TSH) were measured. Results: The serum thiocyanate levels showed highly statistically significant difference among exposed workers when compared to the control. A highly statistically significant lower serum levels of T3 and T4 among the exposed group, and higher serum levels of TSH compared to the control group. Serum TSH showed a statistically significant positive correlation with serum thiocyante among the exposed workers, a statistically significant negative correlation as regards T3, and a negative correlation between TSH and T4 but it is not statistically significant. Conclusion: Cyanide exposure is associated with decrease in thyroid functions but not clinically detected.

Introduction: Workers represent half of the world’s population. Maintaining a safe working environment is reflected on a healthy worker. Some reasons for not implementing the safety policy by most developing countries are lack of effective enforcement system, lack of information and accurate records of occupational diseases and accidents, and lack of basic professional training in occupational health and safety. Aim of Work: To assess a technical school students’ knowledge, attitude, and practice toward the occupational health hazards. Changes in their knowledge were also measured before & after the health education session. Materials and Methods: A health education training session was done on fifty students in a technical education school in Abbasia district, Cairo. Their level of knowledge regarding occupational health was measured by means of a questionnaire distributed among them before and after the session. Results: Only 12.2 % of studied students have reported a previous training on occupational hazards. Thirty five students (71.4%) reported that their work require personal protective equipments (PPEs), 63.3% of students reported that they are protective to their health in workplace and 61.2% prefer to wear them; however only 26.5 % were always wearing them. Only about half of students (51%) knew the correct definition of periodic medical examination. After the health education program, there was a statistically significant improvement in the knowledge of occupational law, proper management of chemical spill and knowledge of hazard of machinery noise. Conclusion: Technical school students require further training sessions to provide them with the knowledge needed to protect themselves and their working environment.

Introduction: Structural scoliosis is a twisting deformity in the curve of vertebral column to the lateral side with simultaneous rotation of the vertebrae, which occurs during the growing years from 10 years to the puberty. Aim of the study: Studies investigating balance problems specific to scoliotic patients showed that those patients reveal variable balance abnormalities. In this study we evaluated the difference in postural stability responses between female patients (students, office workers and shish weapon players) with structural scoliosis and normal subjects. Materials and Methods: Sixty subjects participated in this study. Thirty female patients with structural scoliosis with a mean age of 19.5 ( ± 3.26) years, with Cobb’s angle ranged from 20º to 40° in the major curves, and thirty healthy female subjects with a mean age of 19.36 ( ± 2.41) years. Postural stability of both groups was evaluated by the Biodex Stability System. Results: There was no significant difference between both groups in dynamic balance test. Conclusion: As there was no significant difference between both groups in balance response, it is not recommended to add balance training as an extra physical therapy program for adolescent idiopathic scoliosis (AIS) female patients.

Nowadays a special attention is focused on a variety of Occupational and Environmental exposures and their impact on male and female reproductive health. Such exposures may negatively affect the reproductive process causing reduced fertility and adverse pregnancy outcomes in the exposed population.This article aims at evaluating the impact of Occupational and Environmental exposures to several widespread toxicants on reproductive health by reviewing most recent published literature. The results from the presented studies suggest that there are strong and rather consistent indications that the reproductive system is particularly vulnerable to insult from exposure to widespread occupational and environmental agents. Considering the possible health effects, more epidemiologic data is needed.

Introduction: Rotating night shift work disrupts circadian rhythms and it has been associated with chronic conditions including cancers, cardiovascular diseases, obesity, metabolic syndrome and glucose dysregulation. Aim of work: the study aimed at determining the prevalence of glucose abnormalities among Abo-Korkas sugar factory workers and exploring the impact of rotating night shifts on glycemic state and control of diabetes. Materials and Methods: In a cross-sectional study a total of 330 male workers at Abo-Korkas sugar factory were randomly selected to fill out an interview questionnaire, have medical examination and be tested for fasting and post-prandial blood glucose level; with assessment of HbA1c (Hemoglobin A1c test) for those who were diagnosed as diabetics. Results: Our findings showed that 61 (18.4%) workers were diabetics, 7 of them were newly diagnosed diabetics. The prevalence of diabetes was significantly higher (p= 0.01) among former (33.3%) and current (15.7%) night shift than day-time workers (14.4%). The crude Odds Ratio (OR) for developing diabetes mellitus among the current and former shift workers were 1.1 (0.56-2.18) and 2.9 (1.39-6.31), respectively. Moreover, shift working significantly affected diabetes control (p= 0.04) with an OR= 3.83 (1.02-14.34). Conclusion: Rotating shift work especially night shifts have negative effects on health. It was found to be associated with developing type 2 diabetes mellitus and it hindered diabetes control among night shift diabetic workers. Preventive programs should be implemented for high risk employees. Occupational health practitioners should be aware of such associations that will help them in prevention and management of diabetic employees.

Introduction: Immunoglobulin A (IgA) is the main class of antibodies present in the body secreted fluids such as saliva, tears or mucus from the intestines. The meaning of IgA in serum is still unclear. It was postulated that this immunoglobulin performs a complementary role in the neutralization of the pathogens, which defeated the mucosal barrier, as well as macrophage activation, and removal of immune complexes formed with the participation of this isotype. Aim of Work: To investigate the effects of resistance exercise on Cortisol, Immunoglobulin A (IgA), and Creatine kinase (CK) responses of male students. Materials and Methods: Ten subjects (mean age 21.0 ± 1.5 years) completed two trail, aerobic Treadmill exercises (60% VO2max; 45-min) and resistance (80% 1RM; 45-min) exercise concurrently; each subject was his own control. Blood samples were collected pre-exercise, post-exercise, and 3 hours after exercise. One-way ANOVA with repeated measure and LSD post-hoc tests were used to evaluate changes in Cortisol, CK, and IgA during baseline and exercise periods. Results: During baseline, there were no differences between exercise day (ED) values and those obtained at rest day (RD) for Cortisol, CK, and IgA. After exercise, Cortisol concentration in ED was significantly higher than RD (p<0.05); however, changes in IgA and CK responses were not significant. Conclusions: This type of consecutive exercise didn’t increase susceptibility to upper respiratory tract infection and muscle damage. Therefore, it can be useful for the preparation phase of training for athletes.

Introduction: The higher spectrum is associated with wellbeing and diseases. Maximal oxygen uptake is regarded as the gold standard in the assessment of cardio respiratory power (CRP), but it is expensive equipment, and need well-trained staff, so we need an alternative assessment methods. Sub-maximal measures overcome certain limitations connected with maximal testing; they are easier to administer and less expensive. The YMCA Step Test estimates the HR during the first minute of recovery after 3 minutes of stepping up and down, i.e. the lower the heart rate, the higher the CRP. Aim of Work: To examine the association between two sub-maximal (physical working capacity at a heart rate of 170 (PWC170) on cycle ergometer test and YMCA Step Test) and maximal measures (maximal oxygen uptake (VO2max) of aerobic power, as well as to study the repeatability of the aforementioned sub-maximal measures in physically active female adolescents. Material and Methods: Ten female adolescents aged 13.4 ± 0.7 years old, all members of a local track and field sport club, performed the PWC170 and YMCA Step Test twice. The tests were separated by an interval of one week. During the second laboratory visit, VO2max was measured during a graded exercise test. Results: Considering the repeatability of sub-maximal measures, intraclass correlation coefficient was 0.89 (95% CI 0.55-0.97) and 0.91 (95% CI 0.65-0.98) in absolute and relative to body mass values of PWC170, while it was 0.69 (95% CI -0.27-0.92) with regard to heart rate at the end of step test and 0.78 (95% CI 0.11-0.95) at the end of the first minute of recovery after step test. PWC170 was associated significantly with VO2max in absolute values (r = 0.65, p = 0.04), but not with VO2max relative to body mass values (r = 0.44, p = 0.20). The corresponding relationships between relative PWC170 and VO2max were r = 0.39 (p = 0.27) and r = 0.60 (p = 0.06). Heart rate at the end of the step test was non-significantly related to VO2max in both absolute and relative values (r = -0.53, p = 0.12 and r = -0.61, p = 0.06), whereas respective values of heart rate at the end of the first minute after step test were r = -0.72 (p = 0.02) and r = -0.69 (p = 0.03).Conclusion: These sub-maximal measures appeared to be valid and reliable, and they were recommended for further use in similar population with the assumption that a familiarization session was preceded.

Introduction: Occupational lead exposure increases the risk for adverse renal outcomes. Lead has been reported to cause nephrotoxicity by several mechanisms. Moreover, lead toxicity induces various effects on many organs. Aim of Work: to study the association between blood lead level and some renal and clinical parameters among workers exposed to lead. Materials and Methods: The study included 120 lead exposed workers (galvanic painting) seeking periodic medical examination. The workers answered a questionnaire including questions regarding their socio-demographic characteristics and medical complaints. Also, a blood sample was withdrawn for measuring blood lead level, serum creatinine, serum uric acid and blood urea. Results: The percentage of workers with blood lead level ≥ 20 microgram/dl (μg/dl) presenting with abdominal pain, tremors and tingling of the extremities was significantly higher than the percentage of workers with blood lead level less than 20 μg/dl reporting the same symptoms. Moreover, the mean serum uric acid was significantly higher among workers with blood lead level ≥ 20 μg/dl than among those with blood lead level less than 20μg/dl. Conclusion: Lead exposed workers are at risk of several system affection including the kidneys. This necessitates the undertaking preventive measures to control exposure at the workplace and also periodic medical examination is highly recommended.
