National Institute of Advanced Industrial Science and Technology is working for the Global Alliance to Eliminate Lead Paint (GAELP) of the United Nations Environment Program (UNEP), under the cooperation of Iwate Medical University Cyclotron Center and Nishina Memorial Cyclotron Center of Japan Radioisotope Association. In order to demonstrate how the PIXE is useful to monitor lead in human body, hair samples were collected from local communities and analyzed by the PIXE at the University together with the control of office workers. The analysis showed a clear anomaly of lead for factory workers. It is recommended that the PIXE be added as one of the instruments to assist UNEP's lead and other heavy metal studies.

Relevance. The narrowing of the maxilla is one of the most common pathologies in orthodontics. Recent studies show that the narrowing is always asymmetric which is connected to the rotation of the maxilla. To choose the treatment correctly one need a calculation that reveals the asymmetry, which is impossible with using standard indexes.Purpose – to compare efficiency of indexes of Pont and Korkhause with the Kernott's method in patients with narrowing of the maxilla.Materials and methods. The study involved 35 children aged from 8 to 12 years old undergoing dental treatment in the University Children's Clinical Hospital of the First Moscow State Medical University with no comorbidities. For every patient a gypsum model was prepared and after that to carry out the biometrical calculation. In this study two indexes were used: Pont's index and Korkhause's; using this standard analysis the narrowing of the maxilla was revealed. After using Pont's Index and Korkhaus analysis all the models were calculated by the method of Kernott with Kernott's dynamic pentagon.Results. As a result of the analysis of the control diagnostic models a narrowing of the maxilla in 69% of cases (n = 24) was revealed in all cases, the deviation of the size of the dentition was asymmetric. Thus, 65% of the surveyed models showed a narrowing on the right. This narrowing was of a different severity and averaged 15 control models.Conclusions. This shows that for the biometrics of diagnostic models it is necessary to use methods that allow to estimate the width of the dentition rows on the left and on the right separately. To correct the asymmetric narrowing of the dentition, it is preferable to use non-classical expanding devices that act equally on the left and right sides separetly.

ObjectiveTo identify attitudes and understanding of Chinese undergraduate nursing students towards disaster, therefore providing information for the development of a disaster nursing curriculum in the Chinese context.MethodsA total 214 undergraduate nursing students (Year 1 to 4) in one medical university in China were surveyed in 2010.ResultsThe majority of undergraduate nursing students (94.9%) were concerned about disaster, 46.7% of them thought they were very knowledgeable about disaster, while 39.3% of them stated they were moderately knowledgeable about disaster. The most popular way for the students to get information about disaster was television (88.3%), followed by internet (67.8%) and newspaper (45.8%). Only 33.6% of them said they gained information from the university. Earthquake (93.7% of students) and flood (36.1% of students) were mentioned by the students as examples of disasters that have occurred in China. The majority of students said the Wenchuan earthquake (2008) was the disaster that had the greatest impression on them. Five aspects were identified from their description of disaster, which included the cause, category, characteristic, impact and type of disaster. 36.4% of students were certain that disaster would happen again in China. A further 50.9% felt disaster was likely. Flood and earthquake were considered the most likely future disasters. 71% of nursing students strongly agreed that being prepared for disaster was important. The main reasons were better preparedness could decrease the damage to property and the incidence of death and injury. However, the level of understanding of the effects of disaster and the exposure of students to education about disaster health response was limited.ConclusionKnowledge and skills for disaster preparedness of nursing students should be strengthened in the medical university.

The aim of the study was to analyse the content of museum labels from various periods in terms of their usefulness in creating new labels for exhibits included in museum collections. Nearly 5,000 museum labels from the years 1811 to 2017 were reviewed, for exhibits at the Museum of Zoology of the Polish Academy of Sciences in Warsaw, Herbarium of the University of Wroclaw, and the Museum of Forensic Medicine at the Medical University of Wroclaw. On the basis of the collected information, an attempt was made to develop a ‘universal label’template, including a range of necessary information from the point of view of managing and maintaining the accessibility of the relevant collection.

Background: Smoking is a common habit among the population in Kosovo. In the country, smoking occurs in public places, health and educational institutions despite being prohibited by law. Our objective was to describe smoking habits, knowledge and attitudes among medical students from all departments in the University of Prishtina, Faculty of Medicine. Methods: The present study followed the Global Health Professions Student Survey (GHPSS) standardized methodology including data processing procedures. A self-administered questionnaire used was derived from the GHPSS. A total of 600 students were invited in the study while 470 returned questionnaires and participated in the study. Descriptive statistics were used to present the data. The Fisher’s exact test was used to test the significance and a p-value<0.05 was considered significant. Results: The prevalence rate of smoking among students was 16.9% (95% CI 13.2-20). Current smokers were 79 students, 28.2 % males, and 7.7 % females. The study showed that 55.5% of students smoke less than a pack of cigarettes per day. Almost half of them (47.6%) who smoke reported to have a smoker inside the family.  This study also revealed that 74.7% of respondents smoke in the presence of non-smokers on daily bases. Conclusion: Despite threating their own health, smokers also cause noxiousness to the society and medical students should be role models for the others by not smoking. Even though the percentage doesn’t show a high rate of smokers in Medical University of Prishtina, still we need to pay attention to bad smoking habits and try to lower even more the percentage of smokers.

Abstract Opioids, both naturally occurring and semisynthetic, are effective pain management medications, but also possess the potential for abuse. Analyses of over 37,000 head and body hair samples containing codeine, morphine, hydrocodone, hydromorphone, oxycodone or oxymorphone provide a view of use habits of workplace-testing subjects that cannot be obtained from fluid matrices results. Testing was performed using FDA cleared immunoassays using either 2 ng morphine or oxycodone per 10 mg hair as calibrators. Non-negative screening samples were washed with an extended aqueous wash procedure followed by LC–MS-MS confirmation at a cutoff concentration of 2 ng opioid per 10 mg hair. The LC–MS-MS method measured codeine, morphine, 6-acetylmorphine, hydrocodone, hydromorphone, oxycodone and oxymorphone with an administratively established LOQ of 0.50 ng opioid per 10 mg hair. The linear range was 0.50–100 ng morphine per 10 mg hair, and 0.50–150 ng opioid per 10 mg hair for all other measured analytes. For all analytes, within run precision was ≤5.4%, and between-run precision was ≤6.4%. Analysis of samples containing metabolites found that, among codeine positive samples, 97% contained less than 10% morphine metabolite and 88% less than 20% hydrocodone metabolite, among hydrocodone positive samples, 97% contained less than 10% hydromorphone metabolite and 95% of oxycodone positive samples contained less than 10% oxymorphone metabolite. Our analysis of opioid-positive samples may provide guidelines for interpretation of hair opioid levels typically observed in workplace testing.
