Many legal regulations exist on the hygienic-microbiological properties of food products. The 'Länder-Speiseeisverordnungen' (County Ice Cream Regulations), the 'Diät-Verordnung' (Dietary Regulation) and the 'Trinkwasser-Verordnung' (Regulation on Potable Water) are examples for the frequent inadequacies inherent in these regulations. Caution is indicated against any new proposals for the establishment of additional hygienic-microbiological regulations without sufficient practice-related reasoning unless a revision and improvement of inadequate, already existing regulations has been carried out. Practicable procedures have to be prepared not only to maintain the hygiene in Catering facilities, but also for the evaluation of food products and raw materials according to hygienic-microbiological criteria: Although commonly assumed, the 'Microbe Counts' alone are not sufficient for the determination of the hygienic conditions. Therefore, inspite of all the weak points inherent in quality control procedures - e. g. possible sick, co-workers, only random sample control of raw material supplies - such adapted systems (good manufacturing practice) have to be enforced with special emphasis on the economy of the control expenditure, interdisciplinary aspects, governmental control and consumer information. Examples from literature and own experience demonstrate that the importance of the 'Fecal Indicators' for the judgement of 'hygienic conditions' in food production are rather limited and a correct evaluation only by 'Bacterial Plate Counts' is not possible due to the variation of germ density within one sample. Microbiological investigations of food products according to statistic rules require such an expenditure that they cannot generally be used as routine control procedures. A possible documentation is shown which allows - even without statistic investigations, at least retrospectively - the preparation of a survey on the microbiological properties of raw materials generally available on the market and which makes it possible to recognize and reject any unqualified microbiological limiting value requirements.
The Guideline for Hand Hygiene in Health-Care Settings provides health-care workers (HCWs) with a review of data regarding handwashing and hand antisepsis in health-care settings. In addition, it provides specific recommendations to promote improved hand-hygiene practices and reduce transmission of pathogenic microorganisms to patients and personnel in health-care settings. This report reviews studies published since the 1985 CDC guideline (Garner JS, Favero MS. CDC guideline for handwashing and hospital environmental control, 1985. Infect Control 1986;7:231-43) and the 1995 APIC guideline (Larson EL, APIC Guidelines Committee. APIC guideline for handwashing and hand antisepsis in health care settings. Am J Infect Control 1995;23:251-69) were issued and provides an in-depth review of hand-hygiene practices of HCWs, levels of adherence of personnel to recommended handwashing practices, and factors adversely affecting adherence. New studies of the in vivo efficacy of alcohol-based hand rubs and the low incidence of dermatitis associated with their use are reviewed. Recent studies demonstrating the value of multidisciplinary hand-hygiene promotion programs and the potential role of alcohol-based hand rubs in improving hand-hygiene practices are summarized. Recommendations concerning related issues (e.g., the use of surgical hand antiseptics, hand lotions or creams, and wearing of artificial fingernails) are also included.

The aim of the studies has been to determine the diagnostic clinical value of selected indices and to demonstrate their specific applicability under definite conditions. The study covered 184 subjects in two age groups: young persons aged 15-20 years, and adults being 20-45 years old. The oral hygiene was estimated by the following indices: OHI-S (Oral Hygiene Index-Simplified), Pl. I. (Plaque Index). C.P.I. (Cervical Plaque Index). The ++periodontium state was assessed by using the gingival index (G.I.). Periodontal index was defined by gingival index (G.I.), Russell's periodontal index (P.I.), as well as Kötzschke's periodontal index (K.I.). Sulcus fluid rate (S.F.R.) was also examined by Brill's method. The comparison of numerical values of the indices and statistical analysis of their cross correlation have shown that all of the indices having been involved in the study are of similar diagnostic value. However, C.P.I. appeared to be the best one, since the periodontitis indices most readily reacted to changes of its value. On the other hand, the oral hygiene index (O.H.I.-S) correlated more closely with inflammatory indices in adults, which suggests its particular applicability for examinations in this age group. (Pl. I.) may be used in young persons, in whom there are still no mineralized deposits of tartar. This index is easily determined, thus providing the possibility to evaluate the oral hygiene in quite a short time. Due to the fact that the quantitative measurements of sulcus fluid rate failed to reveal any statistically significant relation between the level of the sulcus fluid and periodontitis as well as oral hygiene in the youth, it has been ascertained that the sulcus rate measurement is of limited usefulness for clinically evaluating the state of parodontium, and may be resorted to in adult individuals only. It has also been disclosed that the resistance of parodontium to the action of pathogenic factors is greater in younger subjects.
Following the Kosovo crisis, this paper questions the contents of hygiene kits to be distributed to refugees, the definition of hygiene and the hygiene promotion practises in emergency aid work. Hygiene promotion cannot be reduced to cleanness promotion. We have to consider refugees' psychosocial needs and trauma as well as the problems of refugees settlement as a community and of community mobilisation to conceive programmes meeting population's needs and demands. Hygiene promotion should include systematic attempts to implement community services by volunteer refugees. One has to be careful also that the financial mechanisms of aid do not pervert programmation.
The purpose of the present study was to determine the effects of vocal hygiene education on the vocal hygiene behaviors and perceptual vocal characteristics of untrained singers. Eleven adult untrained singers served as subjects. They attended four 1-hour class sessions on vocal hygiene, including anatomy and physiology of the phonatory mechanism, vocally abusive behaviors, voice disorders commonly seen in singers, and measures to prevent voice disorders. Pre- and postinstruction surveys were used to record subjects' vocal abuses and their perceptions of their speaking and singing voice. They also rated their perceived value of vocal hygiene education. Results revealed minimal changes in vocal hygiene behaviors and perceptual voice characteristics. The subjects did report a high degree of benefit and learning, however.
New German legislative ordinances prescribe hygiene control in nursing homes and homes for the aged, e. g. the Law for Protection against Infectious Diseases and in North-Rhine Westphalia the Public Health Law. However, there are as yet no clearly defined standards of hygiene because the special features of nursing homes must be considered when applying the "Guidelines for Hospital Hygiene and Prevention of Infections" issued by the Robert Koch Institute. Hence, specific recommendations are given for hygiene of the hands, disinfection, hygienic treatment care, protective and professional clothing, washing of textiles, central kitchen, disposal of waste, house cleaning and handling of drugs and medicines.
UNLABELLED: Guidelines for reprocessing flexible endoscopes have been published in many countries. Compliance to the German guidelines, published in 2002 by the Commission on Hospital Hygiene and Infection Prevention on the Robert Koch Institute is mandatory in all endoscopic units, in hospitals as well as in private practices. Here, a survey of current reprocessing practices in an urban region in Germany is published, covering all hospitals and private practices in this region. MATERIAL AND METHODS: In summer 2003, all endoscopic units in Frankfurt/Main, Germany--15 hospitals and 23 private practices -- were visited by members of the public health service, using a checklist based on the recommendations of the German guideline. RESULTS: In these institutions, more than 70 000 endoscopic examinations per year are performed. 87 % (13 /15) of the hospitals and 43 % (10/23) of the practices, reported to conduct more than 1000 procedures per year. Great differences were found in hygienic quality comparing endoscopic units in hospitals and in private practices. In hospitals compliance with the guidelines was satisfactory. Main problems in the practices were: missing facilities for ultrasonic cleaning (74%) and sterilizing (43%), faults in reprocessing the bottle and tube for air/water-channel flushing (26%) which was filled in with water not sterilised (48%), storage of the endoscope with risk of recontamination (48%), missing routine-tests of the endoscopes after reprocessing (44%). Generally, hygienic conditions and procedures were worse in smaller units than in bigger ones. DISCUSSION: The data from Frankfurt hospitals are satisfactory. In private practices, however, especially in smaller ones, improvements are mandatory. Improvements should cover the quality of structure and process, i.e. specific education of the nurses, availability of ultrasonic cleaners and sterilizators and -- preferably -- automatic dishwashers, as well as implementation of a written protocol for hygiene in endoscopy, based on the German Guidelines.
As the population of the United States becomes increasingly diverse, effective, client-centered, contemporary dental hygiene practice will be realized only if clinicians are equipped to interact with and provide care for clients of varied cultural backgrounds. The purpose of this investigation is to explore ways to incorporate cultural care into the dental hygiene process of care. In addition to a discussion of the integration of cultural sensitivity into communication, assessment, dental hygiene diagnosis, treatment planning, implementation provides recommendations for further research and for the education of both dental hygiene students and practicing dental hygienists in order to facilitate quality care for a culturally diverse clientele.
College students are known for their variable sleep schedules. Such schedules, along with other common student practices (e.g., alcohol and caffeine consumption), are associated with poor sleep hygiene. Researchers have demonstrated in clinical populations that improving sleep hygiene knowledge and practices is an effective treatment for insomnia. However, researchers who have examined relationships between sleep hygiene and practices in nonclinical samples and overall sleep quality have produced inconsistent findings, perhaps because of questionable measures. In this study, the authors used psychometrically sound instruments to examine these variables and to counter the shortcomings in previous investigations. Their findings suggest that knowledge of sleep hygiene is related to sleep practices, which, in turn, is related to overall sleep quality. The data from their regression modeling indicated that variable sleep schedules, going to bed thirsty, environmental noise, and worrying while falling asleep contribute to poor sleep quality.
The creation and organization of sanitary-hygienic zones plays a significant role in diminishing technological pressing on residents of industrialized cities. There are three positions that may be considered in connection with this problem. The first one consists in deflating the size of a sanitary-hygienic zone together with substantiated modifications in the conventional production classification for industrials which apply nature-conservative technology. The second position implies that the size of a sanitary-hygienic zone should be determined by the industrial with the greatest technological pressing on the atmosphere among those going to be situated in the given territory. The third position implies that large industrial complexes must find financial resources to systematically modernize their technological equipment and introduce effective nature-conservative constructions to diminish the intensity and spread of pollutants in the atmosphere. The question of sanitary-hygienic zones along the reservoir banks is also topical.
This study was conducted to investigate the career history and perceptions about dental hygiene education programs among the alumni (1952-1999 graduates) of the School of Dental Hygiene in Tokyo Medical and Dental University. A questionnaire containing demographic, practice characteristics and views on the programs was mailed to 997 alumni in 1999, and 576 alumni (57.8%) responded. Three hundred and forty-one respondents worked as dental hygienists. The majority who responded were in clinical practice. One hundred and thirty-one of the respondents worked in private clinics, 76 in public health centers, and 72 in clinics in companies. The rate of them who worked in public health centers was much higher than the national average cited in the Statistical Report on Public Health Administration and Services. Two hundred and ninety-one respondents reported inadequate programs. The rate of them who reported inadequate programs was significantly higher in alumni who were working than in alumni who were not. The items cited as insufficiently taught at the school were clinical practice, instrumentation, foreign language, psychology, counseling, and nursing related subjects. Thus, many alumni suggested the need for better programs and continuing education. From these results, it was suggested that dental hygienists need to change their education programs in order to meet the present and future needs of more diversified society. This view was particularly prevalent among alumni who were working. The result showed that dental hygiene educators and dental hygienists urgently need to reconsider the professionalism of their field.
Most research on hygienic behavior has recorded the time taken by the colony to remove an experimental amount of dead brood, usually after one or two days. We evaluated the time that hygienic (H) and non-hygienic (NH) honey bees take to uncap and remove dead brood in observation hives after the brood was killed using the pin-killing assay. Four experimental colonies were selected as the extreme cases among 108 original colonies. Thirty brood cells were perforated with a pin in two H and two NH colonies and observations were made after 1, 2, 3, 4, 5, 6, and 24 h. Different stages of uncapping and removing were recorded. Differences in uncapping and removal between H and NH colonies were significant for all comparisons made at the different times after perforation. Using observation hives one obtains a better and faster discrimination between H and NH colonies than in full size colonies. It is possible to differentiate H and NH within a few hours after perforating the cells.
