In refractory cases buy discount zocor 20mg cholesterol ratio tc/hdl, antibacterial resistance or noncompliance should be assumed order zocor 40mg without a prescription cholesterol ratio average, and suscep- tibility testing should be undertaken. Gastric pH is low enough to produce extensive cross-linking and polymerization of sucralfate. Sucralfate has a particular affinity for exposed proteins in the crater of duodenal ulcers; it protects ulcerated areas from further damage and promotes healing. This agent increases lower esophageal tone, stimulates gastric emptying, and increases rate of transit through the small bowel. Metoclopramide is used to treat reflux esophagitis, gastric motor failure, and diabetic gastro- paresis; it is also used to promote advancement of nasoenteric feeding tubes in critically ill patients. Metoclopramide produces sedation, extrapyramidal effects, and increased prolactin secretion. Ursodiol is an oral agent; it requires administration for months to reach full effect. This drug’s conjugated form reduces hepatic synthesis and secretion of cholesterol into bile, and its reabsorption by the intestine. This agent may be used for prevention of gallstones in patients who are undergoing rapid weight loss, such as gastric bypass patients. Digestive enzyme replacements are preparations of semipurified enzymes, typically extracted from pig pancreas. They contain various mixtures of lipase, proteolytic enzymes such as tryp- sin, and amylase. These agents include pancrelipase (Cotazym-S, Entolase, others) and lactase (LactAid). Digestive enzyme replacements are used to treat exocrine pancreatic insufficiency, cystic fi- brosis, and steatorrhea. Laxatives (stool softeners, antidiarrheals) act primarily on the large intestine to promote an increase in the fluid accumulated in the bowel, decrease net absorption of fluid from the bowel, or alter bowel motility. Laxa- tives should not be used chronically as they may induce ‘‘laxative dependence. Bulk-forming laxatives include psyllium (Metamucil, others), methylcellulose (Citrucel), and polycarbophil (Fibercon, Fiber Lax). Bulk-forming laxatives are hydrophilic natural or semisynthetic polysaccharide or cellulose derivatives that are poorly absorbed from the bowel lumen and retain water in the bowel. Bulk-forming laxatives produce laxation after 2–4 days; adequate hydration is required. Salt-containing osmotic laxatives (saline laxatives) (1) Salt-containing osmotic laxatives include magnesium sulfate, magnesium citrate, mag- nesium hydroxide, sodium phosphates, and mineral water. Onset of action typically occurs 3–6 hours after oral administration and 5–15 minutes after rectal administration. In critically ill patients, caution should be used before administering these agents as they cause intra- vascular volume depletion and may lead to exacerbation of hypovolemic shock. Salt-free osmotic laxatives (1) Salt-free osmotic laxatives include glycerin, lactulose (Chronulac), and polyethylene glycol-electrolyte solutions (Colyte, Go-Lytely). Irritant laxatives include diphenylmethane derivatives such as bisacodyl (Modane, Dulco- lax), the anthraquinone derivative senna (Senokot), and castor oil. Irritant laxatives stimulate smooth muscle contractions resulting from their irritant action on the bowel mucosa. The increased luminal contents stimulate reflex peristalsis, and the irritant action stimulates peristalsis directly. The onset of action occurs in 6–12 hours; these agents require adequate hydration. Chronic use of irritant laxatives may result in cathartic colon, a condition of colonic disten- tion, and development of laxative dependence. Stool softeners have a detergent action that facilitates the mixing of water and fatty substan- ces to increase luminal mass. These agents are marginally effective and are used to produce short-term laxation and to reduce straining at defecation. They are also used to prevent constipation; they are not effective in treating ongoing constipation. Mineral oil, now seldom used clinically due to its potentially serious adverse actions, coats fecal contents and thereby inhibits absorption of water. Antidiarrheal agents aim to decrease fecal water content by increasing solute absorption and decreasing intestinal secretion and motility.

Stainless-steel crowns are also advocated for hypoplastic or very carious first permanent molars cheap 10 mg zocor amex cholesterol melting point, where they act as provisional restorations prior either to strategic removal at age 9-12 years or later restoration with a cast crown (Fig order 40 mg zocor otc cholesterol killer foods. Etched retained castings may now be used for the definitive restoration of permanent hypoplastic teeth without involvement of the approximal surface; more conservative provisional restorations than stainless-steel crowns should be considered if this is intended. Composite resin Composite resins came on the market in the early 1970s and have been modified since then in an attempt to improve their properties. Current materials are still best applied to anterior teeth and small restorations in posterior teeth. The development of acid etching at the time that these materials were introduced has ensured that they have performed reasonably well in terms of marginal seal. They are sensitive to variations in technique and take longer to place than equivalent amalgam restorations. The long-term success of composite resins is jeopardized by their instability in water. The best materials have maximum inorganic filler levels and low water absorption, but will deteriorate over time. Key Point • All composite resin and glass ionomer restorations must be placed in a dry field. Glass ionomer Glass ionomer cements came on to the market in the late 1970s and have also been modified since then in order to enhance their properties. Current materials are much improved and have some advantages over composite resins. Being made from glasses with a high fluoride content they not only provide a sustained release over an extended period but also act as a rechargeable reservoir of fluoride, which may protect adjacent surfaces from caries progression. They adhere to enamel and dentine without the need for acid etching, do not suffer from polymerization shrinkage, and, once set, are dimensionally stable in conditions of high humidity such as exist in the mouth (Fig. Similarly to composite resins it is imperative that they are placed in a dry field. None of them have had more than 3-4 year clinical trials so it is still unclear how valuable they are compared to conventional materials. They can be classified according to whether they retain the essential acid-base reaction of the glass ionomers or not. Resin-modified glass ionomer These consist of a glass ionomer cement to which has been added a resin system that will allow the material to set quickly using light or chemical catalysts (or both) while allowing the acid-base reaction of the glass ionomer to take place. Thus, the materials will set, albeit rather slowly, without the need for the resin system and the essential qualities of a glass ionomer cement should be retained (Fig. Polyacid-modified composite resin (Compomer) In contrast, these materials have a much higher content of resin and the acid-base reaction of the glass ionomers does not take place. Therefore although they are easier to use (being premixed in capsules), there is some doubt as to the longer term benefits over conventional composite resins (Fig. However, recently published work has shown compomer to be as durable as amalgam after 3 years in approximal cavities in primary molars (Marks et al. It is perceived as a difficult technique that is expensive in time and arduous for the patient. In fact, once mastered, the technique makes dental care for children easier and a higher standard of care can be achieved in less time than would otherwise be required. In addition, it isolates the child from the operative field making treatment less invasive of their personal space. Nitrous oxide sedation If this is used it is quite likely that mouth breathing by the child will increase the level of the gas in the environment, again putting dentist and staff at risk. The use of rubber dam in this situation will make sure that exhaled gas is routed via the scavenging system attached to the nose piece. Usually less nitrous oxide will be required for a sedative effect, increasing the safety and effectiveness of the procedure. When operative treatment is being performed, all these vital functions are put at risk and any sensible child would be concerned.

Improved productivity means that fewer dentists can produce the same amount of Specialty Training dental services compared to previous years. Ignoring productivity changes is likely to lead to The ratio of general dentists to dental specialists serious miscalculations for workforce policy. While the number of dental dental services) of the dental delivery system tripled school graduates has declined, the number of between 1960 and 1998, growing at an annual rate of graduates of specialty training programs remained 2. Ultimately, this trend will shift the from an increase in the number of dentists or from percentage of specialists to one-third of practicing improved productivity per dentist. During this period it is anticipated into three different periods, based on changes in that 55% of the growth in the United States popu- productivity and the number of dentists (see Table lation will be due to immigrants and their descen- 3.

Alert the Proper Authorities The hospital administration should notify local, municipal, state, and federal health and law enforcement authorities. Bypassing the institutional chain-of-command and protocol will lead to confusion, misinformation, and delay in responding appropriately. The first line of notification in most if not all institutions is infection control or the designated institutional individual for any suspected cases of a contagious disease, whether or not bioterrorism is suspected. All personnel on all shifts should be familiar with the institution’s individual protocol. Confirmatory testing (bioassay and stool cultures) for toxin may be time consuming. Other assays: a vertical-flow strip immunochromatography and a small disposable immunoaffinity column for type A toxin. Serology (enzyme- linked immunosorbent assay) or histologic examination of involved tissue may be needed. Viral hemorrhagic fevers [filoviruses Antigen testing by enzyme-linked immunoabsorbent assay (e. Table 9 Definitive Diagnostics (Continued) Pathogen Diagnostic test Typhus fever (R.

Bioterrorism Infections in Critical Care 473 Assist in the Epidemiologic Investigation and Manage the Psychological Consequences The intensive care team will likely be the first caregivers with an opportunity to obtain detailed information from the patient and/or family. Accurate history-taking (food and water sources, occupation, place of employment, travel, modes of travel and commuting, human and animal contacts, etc. A comprehensive list of hospital personnel, caregiver, and visitor contacts in the intensive care unit must be compiled as soon as the patient arrives at the institution. Data on ambulance personnel or individuals transporting the patient should be gathered upon the patient’s arrival. Protocol should exist detailing the regular and frequent updating of this data, at least for every hospital shift. The number of different caregivers and visitors for the suspect patient should be limited as much as is practical until an etiologic diagnosis is established. The intensive care unit team must consider the distinct possibility that an early casualty may be one of the perpetrators. Clinical specimens should be clearly labeled and preserved for laboratory examination. Establishment and implementation of protocols for chain-of-evidence should be undertaken (99). Usually, the most difficult aspect of chain-of-evidence is identification of the evidence by the individual who collected it. Clothing and personal items may have already been collected from the patient elsewhere. All clothing and personal items must (i) be considered contaminated, and (ii) must be preserved as possible evidence. Transportation to the laboratory should not be through the routine messenger service, but by a person who is familiar with the chain-of-evidence protocol, and is prepared to document the hand-off to the laboratory personnel. Methods of dealing with the psychological effects of a bioterrorist threat is discussed elsewhere (100). Maintain Proficiency and Spread the Word Participation in disaster planning and drills is essential for effective and safe treatment of victims of bioterrorism. To this list, we add rabies, a pathogen that appears to be little appreciated as a possible bioterrorist’s weapon. The virus should be classified as a Category A agent: it is well known to the public, feared, widespread through nature, can be spread person- to-person, may be disseminated by airborne means and through the gastrointestinal tract, has practically a 100% mortality, and rabies vaccination is viewed by the public with great apprehension.
