Background: Epistaxis is one of the commonest emergencies encountered by ENT physicians as well as to family and emergency physicians. It is common among school children as they are easily injured during different school activities. Objective: The aim of this study was to assess the level of knowledge and attitude regarding first aid management of epistaxis among school teachers in Al-Ahsa, Saudi Arabia. Method: A cross sectional study was conducted in November 2017 among Saudi school teachers in AlAhssa region, Kingdom of Saudi Arabia. The data were collected by a well-structured online questionnaire which was designed including questions about the biographical data of the teacher, questions about the past knowledge of the emergency management of epistaxis and questions assessing the awareness of the method applied as a management of epistaxis. Result: We received 485 valid responses. 76% of teachers were female, 93% worked in public and 40% were in primary schools. 54% of participants had received information about first aid to stop nose bleeding or hemorrhage. 67% said that their students experienced epistaxis before. Interestingly, 15% said they would not try to stop the bleeding, and only 25% said they would press on the cartilaginous part of nose. However, a higher percentage (57%) knew that they should tilt the head forward.

Background: Toxoplasmosis is a worldwide disease that severely affects the fetuses and immunocompromised patients and results in many critical and life threatening conditions. The present study aimed to evaluate the awareness of toxoplasmosis and its preventive behaviors among female students in King Faisal University in Al-Ahssa. Subjects and methods: A cross sectional study was conducted in April 2014 among female students in KFU. The data were collected by a questionnaire from 88 participants. Results: Results showed that 65.4% were not aware of toxoplasmosis, and only 28.2% were aware of its complications or risk factors. This study showed that some people are at risk to get toxoplasmosis as they do not wash their hands with water and soap before eating (48.8%), do not wash the fruits and vegetables with water and soap (78.2%), drink tank water (51.3%) and cat owners don’t follow the proper measures for their cats. However, some people practice some of the preventive behaviors as they do not raise the cats (93.6%) and do not consume unpasteurized or unboiled milk (100%) or undercooked meat (92.3%). Conclusion: The current study proved the low awareness of toxoplasmosis which emphasized the need to educate the people in Al-Ahssa about the preventive methods, especially the pregnant women to prevent the severe complications of congenital infections.

Spectroscopic Characterization, Molecular Modeling and DFT/TD-DFT/PCM Calculations of Novel Hydrogen-Bonded Charge Transfer Complex between Chloranilic Acid and 2-Amino-4,6-Dimethylpyridine

Open Journal of Physical Chemistry 2020年第1期10卷 1-32页

A charge transfer hydrogen bonded complex between the electron donor (proton acceptor) 2-amino-4,6-dimethylpyridine with the electron acceptor (proton donor) chloranilic acid has been synthesized and studied experimentally and theoretically. The stability constant recorded high values indicating the high stability of the formed complex. In chloroform, ethanol, methanol and acetonitrile were found the stoichiometric ratio 1:1. The solid complex was prepared and characterized by different spectroscopy techniques. FTIR, 1H and 13C NMR studies supported the presence of proton and charge transfers in the formed complex. Complemented with experimental results, molecular modelling using the density functional theory (DFT) calculations was carried out in the gas, chloroform and methanol phases where the existence of charge and hydrogen transfers. Finally, a good consistency between experimental and theoretical calculations was found confirming that the applied basis set is the suitable one for the system under investigation.
