Aim of Work: To assess heat stress in hospital kitchen environment through environmental heat measurements using the wet-bulb globe temperature index , to evaluate the prevalence of heat related illness and to detect the impact of chronic indoor occupational heat exposure on the kidney health and functions through measurement of urinary interleukin-18 and neutrophil gelatinase-associated Lipocalin. Materials and Methods: A cross sectional comparative study was conducted upon 87 workers in a large scale hospital kitchen at Cairo, Egypt. The workers were classified into two groups: the directly heat exposed group (40 cookers) who were directly in contact with thermal radiation. The second group was the indirect heat exposed group (47 workers) who were involved in activities away from heat contact. Both groups were subjected to a detailed questionnaire including history of self-reported heat related heat illnesses, clinical examination, measurement of urinary levels of interleukin-18 and neutrophil gelatinase-associated Lipocalin. Environmental heat measurements at different workplaces were assessed. Results: In the cooking areas, the mean value of wet-bulb globe temperature was (32.4±1.4) that exceeded the threshold limit value (TLV) recommended by American Conference of Government Industrial Hygienists (28°C). The median and interquartile range of urinary biomarkers were significantly

Nasal packs medicated with topical agents like mitomycin C have been shown to reduce the formation of synechiae in postoperative patients. Aim: To assess the role of mitomycin-c (MMC) in preventing synechia formation and ostial stenosis following endoscopic nasal surgery. Patients and Methods: This is a prospective comparative study performed at the department of Otorhinolaryngology, El-Zhraa University hospital from January 2018 to December 2019 to evaluate the effect of MMC in prevention of nasal adhesions after endoscopic nasal surgery. A total of fifty (50) patients of different age groups and both sexes were involved in the study and divided into two groups, each group include 25 patients, group A with applying MMC and group B without applying MMC. Results: In the MMC group, there was a reduction of synechia and crustration formation in group A that use MMC than group B without using MMC but with no significance. Conclusion: Mitomycin C (MMC) is safe and beneficial in decreasing adhesion formation after endoscopic nasal surgery.

The current study was conducted to investigate the circulating R. anatipestifer in ducks in Assiut Province and assessing their antimicrobial susceptibility. One-hundred and twenty diseased or freshly dead ducks aging 1-18 weeks were examined. Naturally infected birds showed respiratory, nervous, and locomotor disturbances, and low body weight. R. anatipestifer was detected in 16.6% (20) of birds. Among the bacteriologically positive 20 birds, only 10 could be identified by PCR as R. anatipestifer with a prevalence rate of 8.33%. The sensitivity biogram revealed that all the obtained isolates were sensitive to amoxicillin, doxycycline, and flumequine while resistance to streptomycin, chloramphenicol, ampicillin, erythromycin, spectinomycin, and cephradine was observed. On the basis of MIC, all isolates had 90-100% sensitivity to doxycycline and amoxicillin, respectively. Experimentally, the isolated R.anatipestifer strains showed pathogenicity to 14-days-old ducklings.

Surgery for vascular repair is sometimes indicated without angiography. Broadly speaking, options for repair after assessment of vasculature include simple vessel wall repair, venous patching; resection with end-to-end anastomosis or with interpositioning graft, bypass graft, ligation or amputation. General objective of this study is to identify the etiology, presentations, management and outcome of lower limb arterial injuries in Khartoum, Sudan, From September 2013 to September 2014. Methods: Retrospective hospital based study and the study population

In this paper, the fuzzy set theory was applied to ident@ weed species. A membership function was established. The experiment has shown, that the average rate of correct identifkation has improved from 67% to greater than 82%.

The surface water showed very low levels of radionuclide concentrations: <1.0–7.5, 8.5–16.5, <1.6, and <0.1–0.39mBqL−1 for 238U, 226Ra, 222Rn, and 232Th, respectively. Groundwater revealed a significant amount of natural radioactivity (16.1–1720, 7.7–14.3, 3000–139,000,
