Hospital-acquired infections (HAI) reflect as a major global safety concern for both patients and health-care professionals. These infections could be in the form of cross-infection, endogenous infection and environmental Infection. Over 80% of these infections are related to devices' utilization needed for patients' life support. Methods show this is an observational and cross-sectional study, to identify the microorganism and determine the potential source of transmitting of hospital acquired infection by routine devices in adult ICU. The samples were collected using Amies transport media; three swabs were taken from the surfaces of indwelling urinary catheter, mechanical ventilation device and central venous catheter used from every twelve patients. The samples were cultured and analyzed by using microbiologic technique. Finally, all samples analyzed by MicroScan WalkAway 96 pulse. Results showing the most bacteria isolated are "Klebsiella pneumonia" (18.37%), "Acinetobacter baumannii" (11.48%), "Staphylococcus epidermidis" (4.59%), "Staphylococcus haemolyticus" (4.59%), "E. coli" (4.59%), "Serratia marcescens" (2.3%), "Pseudomonas luteola" (2.3%), "Kocurio kristinae" (2.3%) and "Photorhabdus luminscens" (2.3%). This study detects a high contamination of routine devices and resistant organisms. In the end it is recommended that effective infection control practices and effective strategies to control antibiotic-resistant bacteria should be applied.

Water pipe smoking has been practiced extensively for about 400 years. Water pipe smoking is common in the Saudi Arabia. Water-pipe smoking exposes smokers to high levels of tobacco and toxins. An observational and cross-sectional survey carried among 1170 participants to determine the knowledge, attitude, and practice about water-pipe smoking among Saudi population. Data was collected and obtained by the online questionnaire that has been created in Google form and then published in different social media platforms over a period from September 2019 to November 2019. The data were entered in Excel and analyzed in EpiInfo7 statistical software to get descriptive statistics. Results: About 70% were females and 30% male, 43% of them are university students with 83% in the age group of the 18 -25 high participants. Low knowledge of Carbon monoxide poisoning effects = 78%, While 54% of the participants showed low knowledge about infectious disease transmitted by water-pipe. The Knowledge about water pipe contents and carbon monoxide poisoning was low. Further efforts will be necessary to increase the level of awareness among participants in Saudi Arabia regarding water pipe contents and carbon monoxide poisoning.

Oral health is the pathway to one's general health and wellness. Mouthwash is a product used as an adjunct to oral hygiene practices as an antiseptic and antiplaque and antimicrobial agent. The awareness of using mouthwash solution is so limited worldwide. And maybe there's effect of mouthwash on commensal flora. The aim of this study is to measure the effect of using Mouthwash solution on commensal flora of the oral cavity. In this study, we determined three groups, the first group is considered as a basic group where Female students are not using any mouthwash, the second group used mouthwash twice daily for two weeks, group number three used mouthwash twice weekly. We take cytological sample scraping from oral cavity. All the cytological sections of all groups stained with Papanicolaou stain and examined the slides under the microscope. The study came out with the following results: The basic group that did not use any mouthwash remained unchanged, while the second group, who used mouthwash twice daily, showed a clear epithelial tissue for any bacteria and a clear background. Group number three, who used mouthwash twice a week, showed countable bacteria in epithelial tissue with a clear background. Finally, the study concluded: Cosmetic mouthwash solution has a bad effect on commensal flora if you over used it and leads to killing all your normal flora in oral cavity as much as therapeutic mouthwash will do.
