Hypertensive disorders are defined as codes 401–405 in Section 7: Diseases of the Circulatory System (390– 459). Notably, this section includes codes for diabetic kidney disease, with additional specification by the level of glycemic control (250. Coding should be applied as specifically as possible, with appropriate utilization of 4th and 5th digits. For example, codes are specific for types 1 and 2 diabetes and their complications. Diagnoses of electrolyte disorders should be completely spelled out, ie, hyponatremia and hyperkalemia must not be documented with shorthand forms or symbols: hyponatremia must be used instead of ↓Na and+ hyperkalemia must be used instead of ↑K. Hypertensive nephrosclerosis cannot be coded concurrent with primary hypertension (401. Generalized or regional atherosclerosis often accompanies hypertension and these disorders can also be coded when actively managed. Hypotonicity/hyponatremia, hypertonicity/hypernatremia, dyskalemias, dyscalcemias, phosphorus disorders, and acid-base disturbances should be coded when present, appropriately documented and addressed in the treatment plan (see above). The original document was compiled by Prof Karina Butler, Consultant in Paediatric Infectious Disease, Our Lady’s Hospital for Sick Children, and published by the Health Promotion Unit of the Department of Health in 1995. It was subsequently updated in 2005 with the assistance of the Infectious Diseases Group, Department of Public Health, South Eastern Health Board. Management of Infectious Disease in Childcare Facilities and Other Childcare Settings (http://www. We wish to thank the Scientifc Advisory Committee for permission to adapt much of their material to make it relevant in the education setting. Teaching children the skills of hand washing and cough etiquette is essential in breaking the chain of infection, regardless of the cause. Appropriate vaccination of children, in line with the National Immunisation Guidelines, has resulted in fewer childhood illnesses. Schools are to be complimented for facilitating the Schools Immunisation Programme. Appropriate control measures in schools will minimise transmission both within the school, but also to the wider community. I would like to acknowledge the hard work of the Public Health Medicine Communicable Disease Sub-Group in producing this document. I am confdent that it will be of great assistance to school personnel as they continue to play their role in controlling infectious diseases. From time to time, there will be additions and links to other resources that relate to the management of infectious diseases in schools. Introduction These guidelines were designed to assist schools to prevent or minimise the spread of infection, illness and disease to staff, pupils and others (such as student teachers and volunteers). They were primarily developed for use by teachers in primary and secondary schools. They aim to raise awareness about common and important infectious diseases and provide guidance on the prevention and management of infectious diseases in educational settings. The guidelines are based on best available evidence and consensus recommendations. Additional advice and support about specifc infectious diseases can be obtained from Local Departments of Public Health The document provides advice on the prevention and control of the most common and important infections encountered in schools.

However, it is during the times when it does found his subjects had a very difﬁcult time articulating their not work, whether because of lack of knowledge or because strategies. A striking example derives from surveys of real world, either in content or in difﬁculty.

As a specific example order digoxin 0.25mg on-line pulse pressure below 20, body fat was shown to have a “U” shaped relation to mortality (Yao et al. A number of studies have attempted to ascertain the relation- ship between saturated fatty acid intake and body mass index, and these results are mixed. Saturated fatty acid intake was shown to be positively associated with body mass index or percent of body fat (Doucet et al. In contrast, no relationship was observed for saturated fatty acid intake and body weight (González et al. Epidemiological studies have been conducted to ascertain the association between the intake of saturated fatty acids and the risk of diabetes. Several large epidemio- logical studies, however, showed increased risk of diabetes with increased intake of saturated fatty acids (Feskens et al. The Normative Aging Study found that a diet high in saturated fatty acids was an independent predictor for both fasting and postprandial insulin concentration (Parker et al. Postprandial glucose and insulin concentrations were not significantly different in men who ingested three different levels of saturated fatty acids (Roche et al. Fasching and coworkers (1996) reported no difference in insulin secretion or sensitivity in men who con- sumed a 33 percent saturated, monounsaturated, or polyunsaturated fatty acid diet. There was no difference in postprandial glucose or insulin con- centration when healthy adults were fed butter or olive oil (Thomsen et al. Louheranta and colleagues (1998) found no difference in glucose tolerance and insulin sensitivity in healthy women fed either a high oleic or stearic acid diet. It is neither possible nor advisable to achieve 0 percent of energy from satu- rated fatty acids in typical whole-food diets. This is because all fat and oil sources are mixtures of fatty acids, and consuming 0 percent of energy would require extraordinary changes in patterns of dietary intake, such as the inclusion of fats and oils devoid of saturated fatty acids, which are presently unavailable. It is possible to consume a diet low in saturated fatty acids by following the dietary guidance provided in Chapter 11. Within the range of usual intake, there are no clearly established adverse effects of n-9 monounsaturated fatty acids in humans. There is some preliminary evidence that a meal providing 50 g of fat from olive oil reduced brachial artery flow-mediated vasodilation by 31 percent in 10 healthy, normolipidemic individuals versus canola oil or salmon (Vogel et al. Dietary mono- unsaturated fatty acids induce atherogenesis due to greater hepatic lipid concentrations (i. Overconsumption of energy related to a high n-9 mono- unsaturated fatty acid and high fat diet is another potential risk associated with excess consumption of monounsaturated fatty acids. While most epidemiological studies indicate that mono- unsaturated fatty acid intake is not associated with increased risk of most cancers (Holmes et al. There is some epidemiological evidence for a positive association between oleic acid intake and breast cancer risk in women with no history of benign breast disease (Velie et al. In addition, one study reported that women with a family history of colorectal cancer who consumed a diet high in mono- and polyunsaturated fatty acids were at greater risk of colon cancer than women without a family history (Slattery et al. Giovannucci and coworkers (1993) reported a positive association between monounsaturated fatty acid intake and risk of advanced prostate cancer, while two studies observed increased risk of lung cancer (De Stefani et al. Numerous studies have shown suppression of various aspects of human immune function in vitro or ex vivo in peripheral blood mononuclear cells, or in isolated neutrophils or monocytes in individuals provided n-3 polyunsaturated fatty acids as a supplement or as an experimental diet compared with baseline values before the intervention (Table 8-8). This diminished ability, however, is also associated with suppression of inflammatory responses, suggesting benefits for individuals suffering from autoimmune diseases such as rheumatoid arthritis. It seems that the same doses of n-3 fatty acids that may be beneficial in chronic disease preven- tion are doses that are also immunosuppressive. These data support a lack of long-term adverse effect of fish-oil supplementation on cytokine activity. Differences in study design (single treatment versus multitreatment parallel designs) seem to be quite significant in determin- ing whether n-3 fatty acid supplementation exerts immunosuppression or not. For example, the difference in results between Caughey and colleagues (1996) (a baseline comparison study) and Blok and colleagues (1997) (a group comparison study) is not accounted for by greater variability in measurements by the latter group. Therefore, the study by Mølvig and colleagues (1991) showed some concurrence with that of Blok and colleagues (1997) and Caughey and colleagues (1996). Another alternative is to extrapolate from animal studies using model species that are known to have similar immune system components and responsiveness compared to humans. Detailed characterization of appro- priateness of animal models for extrapolation to humans with respect to immunosuppression has not been done.
