If disposable towels are not available a clean towel must be used and replaced with a fresh one whenever it becomes contaminated or soiled, or at the end of each day. Alcohol-based hand rubs can be particularly useful when handwashing facilities are not near to where patient procedures are carried out. Alcohol-based hand rubs should be applied using the same technique as hand washing, with approximately 3 ml of the solution rubbed into hands until dry.

Several studies have that indicated that a relationship between sugars intake and caries still exists in the presence of adequate fluoride exposure (33 cheap 40mg celexa with visa, 71 order celexa 10mg visa, 96, 97). In two major longitudinal studies in children, the observed relationships between sugars intake and development of dental caries remained even after controlling for use of fluoride and oral hygiene practices (66, 67). As mentioned earlier, following a review of available longitudinal studies, Marthaler (68) concluded that, even when preventive measures such as use of fluoride are employed, a relationship between sugars intake and caries still exists. He also stated that in industrialized countries where there is adequate exposure to fluoride, no 113 further reduction in the prevalence and severity of dental caries will be achieved unless the intake of sugars is reduced. A recent systematic review that investigated the importance of sugars intake in caries etiology in populations exposed to fluoride concluded that where there is adequate exposure to fluoride, sugars consumption is a moderate risk factor for caries in most people; moreover sugars consumption is likely to be a more powerful indicator for risk of caries in persons who do not have regular exposure to fluoride. Thus, restricting sugars consumption still has a role to play in the prevention of caries in situations where there is widespread use of fluoride but this role is not as strong as it is without exposure to fluoride (98). Despite the indisputable preventive role of fluoride, there is no strong evidence of a clear relationship between oral cleanliness and levels of dental caries (99--100). Excess ingestion of fluoride during enamel formation can lead to dental fluorosis. This condition is observed particularly in countries that have high levels of fluoride in water supplies (95). Starches and dental caries Epidemiological studies have shown that starch is of low risk to dental caries. People who consume high-starch/low-sugars diets generally have low levels of caries, whereas people who consume low-starch/high- sugars diets have high levels of caries (39, 48, 49, 51, 67, 101, 102). In Norway and Japan the intake of starch increased during the Second World War, yet the occurrence of caries was reduced. Several types of experiment have shown that raw starch is of low cariogenicity (103--105). Cooked starch is about one- third to one-half as cariogenic as sucrose (106, 107). Mixtures of starch and sucrose are, however, potentially more cariogenic than starch alone (108). Plaque pH studies, using an indwelling oral electrode, have shown starch-containing foods reduce plaque pH to below 5. Plaque pH studies measure acid production from a substrate rather than caries development, and take no account of the protective factors found in some starch-containing foods or of the effect of foods on stimulation of salivary flow. Glucose polymers and pre-biotics are increasingly being added to foods in industrialized countries. Evidence on the cariogenicity of these carbohy- drates is sparse and comes from animal studies, plaque pH studies and studies in vitro which suggest that maltodextrins and glucose syrups are cariogenic (109--111). Plaque pH studies and experiments in vitro suggest that isomalto-oligosaccharides and gluco-oligosaccharides may be less 114 acidogenic than sucrose (112--114). There is, however, evidence that fructo-oligosaccharides are as acidogenic as sucrose (115, 116). Fruit and dental caries As habitually consumed, there is little evidence to show that fruit is an important factor in the development of dental caries (67, 117--119). A number of plaque pH studies have found fruit to be acidogenic, although less so than sucrose (120--122). Animal studies have shown that when fruit is consumed in very high frequencies (e. Dietary factors which protect against dental caries Some dietary components protect against dental caries. The cariostatic nature of cheese has been demonstrated in several experimental studies (126, 127), and in human observational studies (67) and intervention studies (128). Cow’s milk contains calcium, phosphorus and casein, all of which are thought to inhibit caries. Several studies have shown that the fall in plaque pH following milk consumption is negligible (129, 130). The cariostatic nature of milk has been demonstrated in animal studies (131, 132). Wholegrain foods have protective properties; they require more mastication thereby stimulating increased saliva flow. Other foods that are good gustatory and/or mechanical stimulants to salivary flow include peanuts, hard cheeses and chewing gum. Both organic and inorganic phosphates (found in unrefined plant foods) have been found to be cariostatic in animal studies, but studies in humans have produced inconclusive results (133, 134). Both animal studies and experimental investigations in humans have shown that black tea extract increases plaque fluoride concentration and reduces the cariogenicity of a sugars- rich diet (135, 136). Breastfeeding and dental caries In line with the positive health effects of breastfeeding, epidemiological studies have associated breastfeeding with low levels of dental caries (137, 138).

Etiology Causative agents include aspirin, hydrogen peroxide, phenol, alcohol, sodiumperborate, silver nitrate, trichloroacetic acid, acid etch- ing liquid, and varnishes of tooth cavities. Clinical features Clinically, the affected mucosa is covered with a white membrane due to necrosis (Figs. The necrotic epithe- liumcan easily be scraped off, leaving a red, bleeding surface. Differential diagnosis Necrotizing ulcerative gingivitis and stomatitis, materia alba, candidiasis, mechanical trauma, bullous diseases. Usage subject to terms and conditions of license 18 White Lesions Candidiasis Definition Candidiasis is the most common oral fungal infection. Etiology It is usually caused by Candida albicans, and less frequently by other fungal species (C. Clinical features Oral candidiasis is classified as primary, consisting of lesions exclusively on the oral and perioral area, and secondary, consist- ing of oral lesions of mucocutaneous disease. Primary candidiasis in- cludes five clinical varieties: pseudomembranous, erythematous, nodu- lar, papillary hyperplasia of the palate, and Candida-associated lesions (angular cheilitis, median rhomboid glossitis, denture stomatitis). Pseudomembranous candidiasis is the most common form of the disease, and is clinically characterized by creamy-white, slightly elevated, re- movable spots or plaques (Fig. The lesions may be localized or generalized, and appear more frequently on the buccal mucosa, soft palate, tongue, and lips. Xerostomia, a burning sensation, and an un- pleasant taste are the most common symptoms. Nodular candidiasis is a chronic formof the disease; it appears clinically as a white, firm, and raised plaque that usually does not detach (Fig. Mucocutaneous candidiasis is a heterogeneous and rare group of clinical syndromes, characterized by chronic lesions of the skin, nails, and mu- cosae, and usually associated with immunological defects. Clinically, the oral lesions appear as white and usually multiple plaques, which cannot be removed (Fig. Laboratory tests Cytology and tissue culture examination; biopsy only in chronic cases.

Treatment Topical antifungal agents (nystatin, azole derivatives, am- photericin B). Chronic Biting Definition and etiology Mild chronic biting of the oral mucosa is relatively common in nervous individuals. These patients consciously bite the buccal mucosa, lips, and tongue, and detach the superficial epithelial layers. Clinical features The lesions are characterized by a diffuse irregular white area of small furrows and desquamation of the epithelium (Fig. Differential diagnosis Candidiasis, lichen planus, leukoplakia, hairy leukoplakia, white sponge nevus, leukoedema, cinnamon contact sto- matitis.

Characteristically, the lesions persist for a short time in one area, then disappear completely and reappear in another area. Differential diagnosis Candidiasis, lichen planus, psoriasis, Reiter syn- drome, syphilitic mucous patches. Usage subject to terms and conditions of license 24 White Lesions Hairy Tongue Definition Hairy tongue is a relatively common disorder that is due to marked accumulation of keratin on the filiform papillae of the tongue, resulting in a hairlike pattern. Predisposing factors are poor oral hygiene, oxidiz- ing mouthwashes, antibiotics, excessive smoking, radiation therapy, emotional stress, and bacterial and Candida species infections. Clinical features Clinically, it is characterized by an asymptomatic elongation of the filiformpapillae of the dorsumof the tongue, some- times extending over several millimeters. Treatment Elimination of predisposing factors, brushing of the tongue, local use of keratolytic agents (trichloroacetic acid, podophyllin). Usage subject to terms and conditions of license 26 White Lesions Furred Tongue Definition Furred tongue is a relatively uncommon disorder, usually appearing during febrile illnesses. Predisposing factors are febrile painful oral lesions, poor oral hygiene, dehydration, and soft diet. Clinical features Clinically, it appears as a white or whitish-yellow thick coating on the dorsal surface of the tongue (Fig. The lesion is due to lengthening of the filiformpapillae, by up to 3–4 mm, and accumulation of debris and bacteria.

One study indicated that 1 in 19 Amish were carriers of the disease and 1 in 1340 Amish babies were born with the disease generic 40mg celexa mastercard. It is also more common The Counsyl Family Prep Screen - Disease Reference Book Page 54 of 287 in the Finnish population where 1 in 76 is a carrier and 1 in 23 purchase 40 mg celexa overnight delivery,000 babies has the disease. Infections, particularly those in childhood, should be given close medical attention. Those with extreme immunodefciency may want to consider bone marrow transplantation to ameliorate this symptom.

The condition causes tissues in the back of the eye, namely the retina, photoreceptors, and choroid (a network of blood vessels that lies between the retina and the white of the eye) to degenerate over time. Night blindness is typically the frst symptom, followed by a loss of peripheral vision. These symptoms typically develop before the age of 20, although the rate of degeneration varies greatly from person to person, even among members of the same family. The Counsyl Family Prep Screen - Disease Reference Book Page 56 of 287 How common is Choroideremia? Fresh fruits and vegetables, an antioxidant supplement, and omega-3 fatty acids—provided either through supplements or foods such as fsh—are often recommended by a physician. Treatments for vision loss are similar to those recommended for any visually- impaired person. Counseling may be helpful to cope with the emotional efects of living with decreased vision. People can live long, productive lives with choroideremia, albeit with progressive visual impairment.

Citrullinemia type I is a disease in which ammonia and other toxic substances build up in the blood, causing life-threatening complications shortly after birth. While infants with citrullinemia type I appear normal at birth, within the frst week of life, most will become lethargic and display poor feeding, vomiting, and seizures that often lead to unconsciousness, stroke, increased pressure around the brain, and death if untreated. While there are less severe and later-onset versions of citrullinemia type I, the mutations for which Counsyl screens are associated with the more severe form that afects infants shortly after birth. Citrullinemia type I belongs to a group of diseases known as urea cycle disorders. Under normal circumstances, the body converts that nitrogen to urea, which is then excreted in urine. People with citrullinemia type I are defcient in an enzyme known as argininosuccinate synthase which is needed for this vital process, leading to a buildup of ammonia and other urea cycle byproducts in the The Counsyl Family Prep Screen - Disease Reference Book Page 58 of 287 body. The goals of treatment for citrullinemia type I are to regulate the amount of ammonia in the blood. Children with citrullinemia will need to be monitored closely by a physician specializing in metabolic disorders. Physicians will also monitor and attempt to relieve any excess of pressure around the brain. The prognosis for a child with citrullinemia type I has not been well established. With treatment, these children can survive for an unknown period of time, however they will have signifcant mental and neurological impairment.

The Counsyl Family Prep Screen - Disease Reference Book Page 60 of 287 People with Batten disease often develop periodic seizures between the ages of 9 and 18. Some people with Batten disease also develop psychiatric problems including disturbed thoughts, attention problems, and aggression. People with Batten disease also show a decline in motor function and may have difculty controlling their own movement. Batten disease is most common in Finland, Sweden, and other parts of northern Europe, but has been seen worldwide. Various medications can be useful for treating seizures, poor muscle tone, sleep disorders, mood disorders, excessive drooling, and digestion.
