旅游应准备哪些药品

由于旅游过程中生活不规律,气候、环境的改变,加之长途跋涉、车船劳顿,难免会发生晕车、失眠、便秘、腹泻、感冒、中署等小毛病,或不小心发生扭伤或跌伤。有人将这些统称为"旅游病"。为了使旅游顺利进行,增添更多乐趣,动身前最好准备些药品,以备应急之用。晕车药有些人坐车、乘船或乘飞机时,会感到头晕目眩、恶心呕吐、面色苍白,可在动身前半小     

呵护前列腺六要素

前列腺是男性独有的附属性腺,如核桃大小,重约20克,位于膀胱下方。前列腺包绕着紧挨膀胱的尿道,它的主要功能是分泌稀薄的前列腺液,构成精液的一部分,同时也是排尿的必经之地。青壮年时期前列腺常受到各种病菌侵袭容易发生炎症。50岁以后,随着睾丸酮及分泌物的减少,同时出现前列腺增生。据统计,60岁以上男

月亮圆缺与人体健康

"晓月过残垒,繁星宿故关";"明月如霜,清景无限"等古诗句,道出了人类与月亮的不解之缘。16世纪时,德国医生帕拉策尔苏斯就认识到:满月时,精神错乱的人数就会增加。因为在满月和新月时,太阳和月亮位于一条直线上,用联合的力量拉地球,大潮就是这时发生的。现代科学研究表明,满月时产生的"生物潮汐",使暴躁的人变得更加神经过敏,忧郁的人变得更加消沉,爱寻欢作乐的人更加喜欢采取异常行动。20世纪70年代,北尼

The human drama of genetics: 'hard' and 'soft' media representations of inherited breast cancer

This paper examines media coverage of 'breast cancer genetics', and explores its implications for public understanding. We present a content analysis of coverage in British newspapers and look at a variety of popular forms, including women's magazines, television soap opera and radio drama. Genetic/inherited risk receives a great deal of coverage across a wide range of media formats and outlets. Much of this attention has focused on individuals from 'high risk families' and dilemmas around prophylactic mastectomies. Through examining media coverage, combined with interviews with media personnel and their sources, we show why this story proved so attractive to the media and highlight the different production values which influence coverage. Finally, we introduce preliminary findings from focus group discussions to demonstrate how such 'human interest' framing has engaged audience attention and influenced public understandings. The paper concludes by highlighting the implications for analysing, predicting, and engaging with, media representations of science.     

Die sogenannte Vinylchlorid-Krankheit—eine berufsbedingte Systemsklerose?

Zusammenfassung Es wurden 13 Arbeiter untersucht, die zwischen 1 3/4 und 18 Jahren in einem PVC-herstellenden Betrieb beschäftigt waren. 8 von ihnen wiesen sklerodermieartige Hautveränderungen (Abb. 2) auf, die histologisch charakterisiert sind durch Verbreiterung und Homogenisierung der kollagenen Faserbündel (Abb. 3 u. 4) sowie Fragmentation und Rarefizierung der elastischen Fasern (Abb. 5). Bei 7 Patienten bestanden trommelschlegelartige Auftreibungen einzelner Fingerendphalangen (Abb. 1). 11 Patienten zeigten Durchblutungsstörungen der Extremitäten (4 von diesen ein Raynaud-Syndrom) und 6 Patienten Acroosteolysen einzelner Fingerendphalangen (Abb. 6, Tabellen 1–3).Darüber hinaus bestand bei allen Patienten eine Thrombocytopenie, bei 12 Patienten eine Splenomegalie, bei 11 Patienten eine Einschränkung der Leberfunktion (erhöhte BSP-Retention). An der Leber ließ sich histologisch bei den 5 laparoskopierten Patienten eine deutliche Fibrosierung der Portalfelder nachweisen. Bei 4 Patienten bestanden Oesophagusvaricen (Tabellen 4 u. 5). 8 Patienten zeigten eine Partialinsuffizienz mit Hinweisen für vorwiegend restriktive Veränderungen.Die hier beschriebenen Veränderungen gehen weit über das bisher bekannte Acroosteolysesyndrom hinaus. Es wird der dringende Verdacht geäußert, daß langfristige Vinylchlorid-Exposition dieses komplexe Krankheitsbild verursacht. Daher wird für diese systemische Krankheit die Bezeichnung Vinylchlorid-Krankheit vorgeschlagen.Wir danken Frau E. Voigtländer für die Herstellung der klinischen und histologischen Abbildungen.     

Empathic processes: perception by medical students of patients'' anxiety and depression

Perceptions by medical students of patients' affective states were investigated, and the effect of the students' own emotions on such perceptions. One hundred and one fourth-year medical students rated the levels of anxiety and depression of three women patients presented on videotape, rated their own levels of anxiety and depression and completed a questionnaire on aspects of the rating process. Students had widely different and often inappropriate perceptions of patients' levels of anxiety and depression. Students who consistently overrated anxiety or depression in patients, compared to those who consistently underrated, were themselves significantly more anxious or depressed. These data suggest a need in medical education for systematic teaching of empathic skills and for recognition of potential bias in clinical decision-making arising from the clinician's own emotional state.     

The reported incidence of work-related ill-health in Scotland (2002-2003)

BACKGROUND: Although incidence data for work-related ill-health in the UK are available, more detailed information for smaller geographical areas has hitherto been unpublished. AIMS: To estimate the incidence of work-related ill-health reported by clinical specialists in Scotland, 2002-2003. METHODS: THOR (The Health and Occupation Reporting network) is a UK wide reporting scheme for work-related ill-health. In 2002-2003, 241 out of 2162 physicians in THOR were based in Scotland. We have summarized the reported cases and calculated incidence rates for categories of ill-health by age, gender and industry. The UK Labour Force Survey (2002) was used to provide denominator data, with comparisons made between rates for Scotland and the rest of the UK. RESULTS: In 2002-2003, 4043 estimated cases were reported from Scotland. Mental ill-health was most frequently reported (41%); followed by musculoskeletal disorders (31%), skin disorders (16%), respiratory disease (10%), hearing disorders (2%) and infection (1%). The reported average annual incidence rate per 100,000 employees for all work-related ill-health in Scotland was 86.0. The highest reported rate for mental ill-health was found for employees in public administration and defence (76.7 per 100,000), and health and social work (72.3 per 100,000). The construction industry had the highest reported rate of musculoskeletal disorders (41.6 per 100,000), while hairdressers appeared at most risk of developing occupational contact dermatitis (rate=86.4 per 100,000). CONCLUSIONS: Despite its limitations, THOR has indicated types of work-related ill-health and related industries for targeted disease prevention in Scotland.     

Function of the protein RPE65 in the visual cycle

A protein called RPE65 performs a key role in the trans-cis isomerization of retinol in the retinal pigment epithelium of the eye. The palmitoylation of RPE65 serves to switch off the visual cycle in darkness and to switch it on in the light.     

Worker education in the primary prevention of occupational dermatoses

This paper reports the evaluation of a skin care education programmeconducted on a fine chemicals manufacturing site where over1,000 employees are located. Approximately 60% are involvedin chemical manufacture. Over a 12 month period production staffreceived training in prevention of occupational dermatoses linkedto a site-wide poster initiative. The incidence of new casesof occupational dermatoses fell from 0.055 (70 cases in 1,277employees) to 0.021 (27 cases in 1,277 employees) before andafter the intervention respectively (p<0.0001). After otherfactors such as chemicals handled, observer bias and changesin reporting related to socioeconomic climate were taken intoaccount it is concluded that this study demonstrates the importanceof worker education as a tool for primary prevention of disease.Training materials such as video and poster presentations maybe effectively used in the chemical manufacturing industry asan adjunct to prevention and control of exposure to substanceshazardous to the skin. Such methods may also be used in otherindustries where there are significant risks of dermatoses.     

Regional Variation in Travel-related Illness acquired in Africa,March 1997–May 2011

To understand geographic variation in travel-related illness acquired in distinct African regions, we used the GeoSentinel Surveillance Network database to analyze records for 16,893 ill travelers returning from Africa over a 14-year period. Travelers to northern Africa most commonly reported gastrointestinal illnesses and dog bites. Febrile illnesses were more common in travelers returning from sub-Saharan countries. Eleven travelers died, 9 of malaria; these deaths occurred mainly among male business travelers to sub-Saharan Africa. The profile of illness varied substantially by region: malaria predominated in travelers returning from Central and Western Africa; schistosomiasis, strongyloidiasis, and dengue from Eastern and Western Africa; and loaisis from Central Africa. There were few reports of vaccine-preventable infections, HIV infection, and tuberculosis. Geographic profiling of illness acquired during travel to Africa guides targeted pretravel advice, expedites diagnosis in ill returning travelers, and may influence destination choices in tourism.     

The design of hazard risk assessment matrices for ranking occupational health risks and their application in mining and minerals processing

Two hazard risk assessment matrices for the ranking of occupational health risks are described. The qualitative matrix uses qualitative measures of probability and consequence to determine risk assessment codes for hazard-disease combinations. A walk-through survey of an underground metalliferous mine and concentrator is used to demonstrate how the qualitative matrix can be applied to determine priorities for the control of occupational health hazards. The semi-quantitative matrix uses attributable risk as a quantitative measure of probability and uses qualitative measures of consequence. A practical application of this matrix is the determination of occupational health priorities using existing epidemiological studies. Calculated attributable risks from epidemiological studies of hazard-disease combinations in mining and minerals processing are used as examples. These historic response data do not reflect the risks associated with current exposures. A method using current exposure data, known exposure-response relationships and the semi-quantitative matrix is proposed for more accurate and current risk rankings.     

Acute symptoms following work with pesticides

BACKGROUND: Serious accidental poisoning by pesticides is rare in the UK, but more minor pesticide-related illness may be under-reported. Anecdotally, use of sheep dip has been linked with flu-like symptoms. AIM: To explore the frequency, nature and determinants of acute symptoms following work with pesticides. METHODS: A postal survey of men in three rural areas of England and Wales provided data on occupational use of five categories of pesticide, occurrence of 12 specified symptoms within 48 h of using pesticides and tendency to somatize. Risk factors for pesticide-related symptoms were assessed by modified Cox regression. RESULTS: Of 10 765 responders (response rate = 31%), 4108 had at some time used pesticides occupationally, including 935 (23%) who reported symptoms following such work on at least one occasion. In two areas, acute symptoms were most frequent following use of sheep dip (29 and 32% of users), but in the third area the rate was significantly lower (13% of users). The relative frequency of symptoms was similar for all five categories of pesticide, and flu-like symptoms did not cluster unusually among users of sheep dip. Risk of pesticide-related symptoms increased with somatizing tendency (prevalence ratio for highest versus lowest category 2.4, 95% confidence interval 2.0-3.0) and was higher in men who had used pesticides most often or handled concentrate. CONCLUSION: Acute symptoms are common following work with pesticides, but in many cases the illness may arise through psychological rather than toxic mechanisms.
