The Rotating sparge arm latter byproducts are highly perishable and are often quickly transported away for direct use as cattle feed. Attempts have also been made to generate further fer mentable brewing sugars from the cellulosic compo nents of spent grains using acid or enzyme hydrolysis (see Chapter 10, Bioconversion of lignocellulose). The objective in mashing is to convert Grain bed Insulation as much of the malt and adjunct starch as possible to fer Slotted false bottom mentable sugars. Starch is composed of 25% amylose, a linear polymer of a-1,4-linked glucose units, and 75% Sweet wort amylopectin, which is a branched polymer containing Fig. A relatively minor role is played by a-glucosidase, which releases g/L single glucose units.

How Yeast characteristics ever, most brews are not pitched with fresh yeast, but Brewers yeast must be effective in taking up nutrients with yeast recovered from a previous fermentation. Surplus yeast may be hibiting higher fermentation rates and greater tolerance used to supplement distillers yeast in whisky fermenta to alcohol.

Nisin, a natural food Current brewers yeast strains cannot directly ferment preservative (see Chapter 13), has been examined as a starch and higher dextrins, hence the necessity for malt replacement for acid-washing. It kills the lactic acid bac ing and mashing processes to generate fermentable teria that spoil beer, but has little or no effect on the sugars. They are used extensively in bread and wine maltose and maltotriose are the main wort fermentable making, but have only recently been advocated for beer sugars (see Table 12. However, in some yeast strains, utilization of the two sugars is subject to catabolite re pression by glucose (see Chapter 3, Microbial metabo Yeast nutrition lism). Consequently, they cannot be metabolized until Brewing yeasts require the following nutrients, which the wort glucose concentration falls below a certain are normally supplied by a well-balanced wort: level, which can be a major limiting in uence on the 1 a carbon and energy source, provided by fermentable overall fermentation rate.

Amino acids are transported into the cell by a limited number of permeases and, like the sugars, they are taken from the wort in a speci ed order. Cooling jacket Although alcoholic fermentations are anaerobic, the initial oxygen concentration of wort is vitally impor tant. The speci c oxygen level required is strain depend ent, but a minimum oxygen concentration of 10mg/L is usually aimed for in wort prior to fermentation. If the oxygen level is inadequate, yeast growth and ethanol production are usually impaired. The oxygen is required for the synthesis of sterols; these unsaturated lipids are Coolant in 70 Inlet/outlet essential cell membrane components. Yeast that has been previously grown aerobically can grow satisfacto rily in conditions of low initial oxygen concentration. However, the yeast in most beer fermentations is derived from a previous anaerobic fermentation and so ferments Fig. They normally have cooling jackets and are tion rates are primarily controlled by adjusting the used to produce both ales and lagers.

Other minor metabolic products that are im period and falls towards the end, as the yeasts occulate. These compounds synthesized from carbohydrates or formed from wort have avour thresholds (the minimum concentration amino acids. Esters are synthesized by the reaction of acyl butanoate (isobutanol) coenzyme A (CoA) esters with alcohols. For example, phenylalanine phenylpyruvate 2-phenylethanol acetyl CoA plus ethanol gives ethyl acetate, which is the main beer ester, alongside isoamyl acetate, isobutyl Greater amounts are generally produced at higher fer acetate, ethyl caproate and phenylethyl acetate. Acetaldehyde (ethanal), the most signi cant aldehyde, has a avour threshold of 15mg/L. Excess Amino acid acetaldehyde is produced if zinc ions are at low concen (valine) tration in the wort, as they are required by the dehydro oxoglutarate genase responsible for the reduction of acetaldehyde to Transamination form ethanol.

Contact with the licensed health care provider for additional comfort measures may be warranted. Bedding and clothing worn next to the skin during the 4 days before initiation of therapy should be laundered in a washing machine with hot water and dried using a hot cycle. Placing items you do not wish to launder in the dryer on the hot cycle for 30 minutes. Scabies is widespread and transmission usually occurs through prolonged, close personal contact. Education about its symptoms and treatment may help those at risk and eliminate spread. It is usually not serious except that it causes severe itching and secondary infection from scratching. Scabies in students, like lice and pinworms, does not necessarily indicate poor hygiene. If repeated infections occur despite proper treatment, an investigation for unrecognized cases among companions or household members should be undertaken. The most common cause of treatment failure is inadequate treatment of close personal contacts. The use of chemical sprays or "bug bombs" to treat the environment within the school setting is not recommended due to potential toxicity and harm to humans. The number of diseases listed in the sexually transmitted category has climbed sharply in recent years. Consider child sexual abuse when gonorrhea, chlamydia, or syphilis is present in a student who is not sexually active. Pain during urination and an opaque discharge from the urethra are the most common symptoms for males, when they do occur. Symptoms for females include mucopurulent cervicitis (inflammation of the cervix), cervical ectopy (redness) and friability (easily induced bleeding) of the cervix. If left untreated, complications may occur, including pelvic inflammatory disease and chronic pelvic pain in females and epididymitis (inflammation of the testes) in males. Mode of Transmission Chlamydia is transmitted by sexual activity involving the penis, vagina, mouth, and/or rectum. Infectious Period Chlamydia infection may extend for months in untreated cases, especially in asymptomatic cases. If clinical services to support Chlamydia diagnosis and treatment exist at the school. Control of spread involves an interview with the patient and tracing of sexual contacts by public health personnel. Gonorrhea genital infections differ somewhat in presentation in males and females. Infection can spread to the pelvic areas and even to the joints, heart, brain, and other organs in both males and females. Coexisting chlamydial infection and potential pelvic inflammatory disease should be a concern, along with pharyngeal (throat) and anorectal infections. Mode of Transmission Gonorrhea is transmitted by sexual activity involving the penis, vagina, mouth, and/or rectum. Infectious Period Gonorrhea may extend for months in untreated cases, especially in asymptomatic cases. Make referral to licensed health care provider for diagnosis and appropriate therapy. If clinical services to support gonorrhea diagnosis and treatment exist at the school. Consider child sexual abuse when gonorrhea is present in a student who is not sexually active. Antibiotic resistant strains of gonorrhea may increase the risk of spreading this infection. School nurses should work closely with local health jurisdiction staff to better ensure successful treatment and discuss any student who reports his/her symptoms have not resolved. As with oral herpes infections, this is a recurrent, life-long, viral infection but is asymptomatic or not recognized in at least two-thirds of those infected. Genital lesions pose no risk to others unless there is direct contact with infected lesions. Genital herpes infection, due to either Type 1 or Type 2 virus, can be sexually transmitted. Intermittent or suppressive therapy with specific antivirals may alleviate outbreaks and viral shedding and have been shown to reduce transmission. Provide education and counseling regarding transmission of disease, recurrence potential, and recommended prevention practices to prevent spread. If clinical services to support initial herpes diagnosis and treatment exist at the school. Two strains are responsible for approximately 70 percent of cervical cancers and another two strains cause 90 percent of genital warts. Provide education and counseling regarding transmission of disease, and recommended prevention practices to prevent spread. While chlamydia is the most frequent isolated agent, other agents are involved in a significant number of cases. Symptoms are very similar to gonorrhea, with pain and a pus-like to mucous-like discharge from the urethra. Diagnosis is based on symptoms, laboratory studies, and negative cultures for gonorrhea. Control of spread involves an interview with the patient and referral of sexual contacts for medical examination and treatment. Schools are required to cooperate with their local health jurisdiction staff in the process of investigation. Infection is characterized first by a local lesion, then a secondary rash, followed by a period of latency (no symptoms), and much later by possible involvement of the nervous system, heart, skin, and bone. The most distinctive early sign is called a chancre (a shallow, painless ulcer with a firm border that is usually located on genital surfaces, but possibly on other areas of the body). At this secondary stage, blood tests for syphilis are always positive (unlike the primary stage that can have negative serologic tests). Patients may remain asymptomatic throughout life or may progress to the late destructive stages of the disease. In an untreated female, syphilis may be transmitted to a fetus regardless of the stage of the disease. Mode of Transmission With the exception of congenital infection, syphilis is transmitted through direct contact with an infectious lesion or rash occurring in primary and secondary stages, typically by sexual contact. Infectious Period Appropriate antibiotic treatment ends infectiousness within 24 hours. If clinical services to support syphilis diagnosis and treatment exist at the school. Control of spread involves an interview with the patient and tracing of all sexual contacts by public health officials for medical examination and treatment. Adequate treatment will limit spread from the primary site to other organs and from one individual to another. The untreated disease may become a very significant health problem in the years ahead. Congenital syphilis such as the infection of a newborn with syphilis contracted from the mother, is a serious and unnecessary tragedy since this disease can be diagnosed and treated effectively. While trichomoniasis infects both males and females, males seldom have any symptoms. Symptoms for females include abnormal vaginal discharge, itching, burning, and vaginal odor. There is evidence linking trichomoniasis infection to low birth weight babies and premature births. Mode of Transmission Trichomoniasis is transmitted through penile-vaginal intercourse. Control of Spread Although the male is seldom symptomatic with trichomoniasis, control of spread and reinfection usually involves concurrent referral of male sexual contacts for medical examination and treatment. Only in this way can the female partner avoid reinfection once therapy is completed. The most prevalent types of vaginitis are trichomoniasis (trich), candidiasis (yeast), and bacterial vaginosis (Gardnerella vaginitis, nonspecific vaginitis). Mode of Transmission Vaginal infections may be transmitted by intimate sexual contact but symptoms also may originate from excessive douching, use of birth control pills, certain antibiotics, and other sources such as allergic reactions to vaginal products. Infectious Period Vaginitis caused by microorganisms is infectious for the duration of infection. If the referred student is of the age of 14 or older and is otherwise competent, written consent from the student must be obtained prior to disclosing such referral and/or treatment information with the students parent/guardian. Lesions begin as raised red spots (papules) and become firm vesicles (blisters) often with a central dimple. Unlike chickenpox, lesions are at the same stage of development at the same time no matter where they are on the body. Crusts begin to form in about 14 days and begin to separate during the third week. Smallpox vaccine is used in special circumstances to vaccinate some military personnel and laboratory workers. The vaccine is created using a different but related virus that causes the same kind of lesion but in a limited area. Mode of Transmission Most transmission of smallpox resulted from direct face-to-face contact with an infected person, usually within a distance of 6 feet, from physical contact with a person with smallpox, or with contaminated articles. Vaccine virus can be spread from the vaccine inoculation site or from fresh scabs to another person by hands or skin contact. Infectious Period Lesions are infectious until the dry scab crusts have separated. A person with smallpox is sometimes contagious with onset of fever, but the person becomes most contagious with the onset of rash. Immediately report to your local health jurisdiction by telephone a suspected case of smallpox or smallpox vaccine rash. Only persons with up-to-date vaccination for smallpox should examine a potential case. Cover lesions from smallpox vaccine, which is a different virus that is also contagious. Use standard precautions including gloves for any contact with dressings or with articles soiled with fluid or scabs from skin lesions. Dispose of all dressings in biohazard bags or disinfect dressings with 1:10 bleach and water solution. Follow recommendations from your local health jurisdiction about exclusion from school. Future Prevention and Education In the event of an intentional release of smallpox virus, vaccination would be recommended for those exposed to the initial release, contacts of people with smallpox, and others at risk of exposure. This site includes updates, links, and education options along with general information. Scarlet fever involves a streptococcal sore throat and a skin rash caused by a toxin produced by certain strains of streptococci. Characteristically, the rash spares the area around the mouth and inside of the elbow. Symptoms include red sores or blisters, often on the face or areas that are scratched like an insect bite (see Impetigo). Necrotizing fasciitis (flesh-eating bacteria) is caused by Group A strep, the same bacteria that causes strep throat and impetigo. Unlike strep throat and impetigo, which are common and easy to treat, necrotizing fasciitis is very rare and more difficult to treat. The infection occurs between the skin (in the fascia) and eventually results in tissue damage to the skin and underlying muscle. The signs and symptoms are fever with severe pain, followed by swelling and redness at a wound site. As with all unidentified rashes, especially those accompanied by fever or illness, make referral to a licensed health care provider. Prevention is practicing proper handwashing techniques and keeping all wounds clean. Untreated milder streptococcal infections can lead to serious complications (rheumatic fever and kidney disease [glomerulonephritis]). Mode of Transmission Streptococcal infection is usually transmitted by airborne droplets or direct skin contact with an infected person. A person can move the infection from one part of the body to another by scratching. Necrotizing fasciitis is spread through direct contact with infected persons through an open sore or wound on the skin. However, if treated with antibiotics, the infectious period can last less than 24 hours. Report to your local health jurisdiction suspected or confirmed outbreaks associated with a school. Refer students with a symptomatic sore throat and/or unexplained fever to a health care provider. Notify parent/guardian of students with history of rheumatic fever or kidney infection (glomerulonephritis) if there is a cluster of streptococcal pharyngitis at school. Students with sore throat and fever should be cultured and, if culture-positive, treated appropriately by a licensed health care provider. Those with a positive throat culture should be excluded until at least 24 hours after antimicrobial treatment is initiated. They should be able to return to school after 24 hours of appropriate treatment, when they have no fever, and when physically well enough to attend. When throat cultures are done on a cluster of students to check for strep, there will almost always be some who test positive but are without any symptoms. Significant increases in the number of sore throats or increases above normal in school absenteeism (above 10 percent) should be referred to your local health jurisdiction for epidemiologic investigation. The culturing of asymptomatic contacts of a strep case is not generally done except in facility outbreaks. Some licensed health care providers will wish to treat these contacts while some will observe for a period of time before treating. Future Prevention and Education As with all antibiotic prescriptions, the family should be encouraged to take (or administer to their child) the full course of prescribed treatment, even if the symptoms disappear before all of the medication is taken. Years of prescribing antibiotics for nonbacterial infections and failing to complete the full courses of treatment have promoted the development of antibiotic-resistant bacteria. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs designed to cure infections. Routine classroom or school culture surveys to find strep carriers are not justified unless local public health officials determine an unusual prevalence of streptococcal disease or its complications (rheumatic fever and kidney disease [glomerulonephritis]). Tetanus growth in a deep wound produces a toxin that can cause localized spasm and pain in the muscles at the site of injury, or severe generalized muscle spasms most marked in the jaw and neck, generalized pain, even seizures, and death. Tetanus has not been reported in the United States in individuals who received an adequate primary immunization series. Mode of Transmission Transmission is through contamination of a wound by soil, dust, water, or articles, especially those that have been contaminated with animal feces or manure. Deep puncture wounds are a particular risk because the bacteria grows in a low-oxygen or oxygen-free environment. Make referral to licensed health care provider for evaluation of the wound for additional medical care if needed and a tetanus booster, if needed. School immunization requirements for Kindergarten and Grade 6 provide adequate immunization levels. Adults who have not received a Tdap booster should get one, then a booster dose of Td every ten years during their lifetime. Tick size varies depending on its developmental stage and recent feeding, varying from 1/8 to 1/2 inches in length. Different species of hard ticks can carry several infectious diseases in the western United States. Diseases and symptoms include: Lyme disease typically starts with an expanding circular target-shape rash. Rare late symptoms include recurring joint pain, heart disease, and nervous system disorders. Rocky Mountain spotted fever typically starts with fever, vomiting, muscle aches, and headache. Symptoms are fever, headache, swollen lymph nodes, and a skin ulcer near the bite.

Chimaeras have a different origin, being derived from the fusion of two different zygotes to form a single embryo. The process of pigmenti, an X linked dominant disorder, lethal in males but not in females, because of functional X chromosomal mosaicism (courtesy of X inactivation occurs in early embryogenesis and is random. Professor Dian Donnai, Regional Genetic Service, St Marys Hospital Thus, alleles that differ between the two chromosomes will be Manchester) expressed in mosaic fashion. Carriers of X linked recessive mutations normally remain asymptomatic as only a proportion of cells have the mutant allele on the active chromosome. Occasional females will, by chance, have the normal X chromosome inactivated in the majority of cells and will then manifest systemic symptoms of the disorder caused by the mutant gene. In X linked dominant disorders such as incontinentia pigmenti, female gene carriers have patchy skin pigmentation that follows Blaschkos lines because of the mixture of normal and mutant cells in the skin during development. Chromosomal mosaicism is not infrequent, and arises by postzygotic errors in mitosis. Mosaicism is observed in conditions such as Turner syndrome and Down syndrome, and the phenotype is less severe than in cases with complete aneuploidy. Mosaicism has been documented for many other numerical or structural chromosomal abnormalities that would be lethal in non-mosaic form. The clinical importance of chromosomal mosaicism detected prenatally may be difficult to Figure 7. The abnormal karyotype detected by amniocentesis or arm of chromosome 12 arrowed) (courtesy of Dr Lorraine Gaunt and chorionic villus sampling may be confined to placental cells, Helena Elliott, Regional Genetic service, St Marys Hospital, Manchester) 32 Unusual inheritance mechanisms but even when present in the fetus the severity with which the No deletion fetus will be affected is difficult to predict. In mendelian disorders this may present as a patchy phenotype, as in segmental neurofibromatosis type 1. Germline mosaicism is one explanation for the transmission of a genetic disorder to more than one offspring by apparently normal parents. In these cases the mutation may be confined to the germline cells or may be present in a proportion of somatic cells as well. Recurrence is caused by gonadal mosaicism, in which the mutation is confined to some of the germline makes it difficult to exclude a risk of recurrence in other cells in the mother X linked recessive disorders where the mothers carrier tests give normal results, and autosomal dominant disorders where the parents are clinically unaffected. This is because only the egg contributes cytoplasm and mitochondria to the zygote. All offspring of a carrier mother may carry the mutation, all offspring of a carrier father will be normal. The pedigree pattern in mitochondrial inheritance may be difficult to recognise, however, because some carrier individuals remain asymptomatic. In Leber hereditary optic neuropathy, which causes sudden and irreversible blindness, for example, half the sons of a carrier mother are affected, but only 1 in 5 of the daughters become symptomatic. With successive cell divisions some mutation to all their offspring, some of whom will develop the disorder. Risks may be related to the probability of a person developing a disorder or to the probability of transmitting it to their offspring. Mathematical risk calculated from the pedigree data may often be modified by additional information, Mode of Result of such as biochemical test results. In an increasing number of inheritance carrier tests disorders, gene carriers can be identified with certainty by gene mutation analysis. Risk calculation remains important, since decisions about whether to proceed with a genetic test are often influenced by the level of risk determined from the pedigree. In such families a clinically unaffected adolescent or young adult has a Example 1 Example 2 Example 3 Example 4 high risk of carrying the gene, but an unaffected elderly relative is unlikely to do so. The prior risk of 50% for A A A A developing the disorder can therefore be modified by age. In example 1 the risk of developing Huntington disease for individual B is still almost 50% at the age of 30. In example 2, individual B Aged 8 Aged 40 Aged 40 Aged 40 remains unaffected at the age of 60 and her residual risk is risk 25% risk 5% risk 2% risk 17% reduced to around 20%. In example 3 the risk to B is reduced to 6% at the age of 70 and the risk to the 40-year old son is less than 2%. In example 4 the risk for C at the age of 40 is only reduced to around 17%, because parent B, although clinically unaffected, died aged 30 while still at almost 50% risk. Example 5 Example 5 When both parents are affected by the same autosomal dominant disorder the risk of having affected children is high, as shown in example 5. The risk of a child being an affected 1/4 1/4 heterozygote is 1 in 2 and of being an affected homozygote is 1 in 4. In most conditions, the phenotype in homozygous Heterozygous affected individuals is more severe than that in heterozygotes, as seen Homozygous affected in familial hypercholesterolaemia and achondroplasia. In Homozygous unaffected some disorders, such as Huntington disease and myotonic dystrophy, the homozygous state is not more severe and this Figure 8. When both parents are affected by different autosomal dominant disorders, the chance of a child being unaffected by Example 6 either condition is again 1 in 4. The risk of being affected by one or other condition is 1 in 2 and the risk of inheriting both conditions is 1 in 4. Reduced penetrance refers to the situation in which not all carriers of a particular dominant gene mutation will develop Figure 8. Example 6 shows the risk to the child and Disease Complication Risk (%) grandchild of an affected individual for a disorder with 80% Neurofibromatosis 1 Learning disability: penetrance in which only 80% of gene mutation carriers mild 30 develop the disorder. In general the risk of clinical disease affecting the Scoliosis 10 grandchild of an affected person is fairly low if the intervening Tuberous sclerosis Epilepsy 60 parent is unaffected. Although syndrome 1 the risk of offspring being affected is 50%, the family may be more concerned to know the likelihood of severe disease occurring. The incidence of severe manifestations or disease complications has been documented for many autosomal disorders, such as neurofibromatosis type 1, and these figures Example 7 can be used in counselling. An affected individual therefore has a 5% risk overall for having a child who will become severely disabled. Occurrence of the same disorder in different sibships within an extended family can occur if the mutant gene is common in the population, or there is multiple consanguinity. Many members Example 8 of the family will, however, be gene carriers and may wish to know the risk for their own children being affected. Example 7 shows the risk for relatives being carriers in a family where an autosomal recessive disorder has occurred, ignoring the possibility that both partners in a particular couple may be carriers apart from the parents of the affected child. In general, doubling the square root of the disease incidence gives a sufficiently accurate estimation of carrier frequency in a given population. Example 9 the unaffected sibling of a person with cystic fibrosis has a carrier risk of 2/3. The unrelated spouse has the population risk of around one in 22 for being a carrier. Since the risk of both parents passing on the mutant gene is one in four if they are both carriers, the risk to their child would be 2/3 1/22 1/4. Example 9 When there is a tradition of consanguinity, more than one 1/2 marriage between related individuals may occur in a family. If a 1/2 Risk of being consanguineous couple have a child affected by an autosomal carrier recessive condition other marriages within the family may be at increased risk for the same condition. The risk can be defined by Risk of affected child 1/2 1/2 1/4=1/16 calculating the carrier risk for both partners as shown in example 9. If carrier tests are possible for a condition that has occurred in the family, testing may provide 1/2 1/2 reassurance, or identify couples whose pregnancies will be at risk, and for whom prenatal diagnosis might be appropriate. Example 10 When an affected person has children, the risk of recurrence is again determined by the chance that the partner is a carrier. In 1/2 non-consanguineous marriages this is calculated from the population carrier frequency. In consanguineous marriages it is calculated from degree of the relationship to the spouse. The affected parent must pass on a gene for the disorder since they are homozygous for this gene and the risk to the offspring is 1/4 therefore half of the spouses carrier risk (the chance that they too would pass on a mutant gene). Risk of affected child Examples 11 and 12 1 1/4 1/2=1/8 Some autosomal recessive disorders, such as severe congenital Figure 8. When both parents are affected by autosomal recesive deafness, the risks to the offspring will depend on whether the parents are homozygous for the same (allelic) or different (non-allelic) Example 11 Example 12 genes. In example 11 both parents have the same form of recessive deafness and all their children will be affected. In example 12 the parents have different forms of recessive deafness due to genes at separate loci. Since the different types of autosomal deafness cannot always be identified by genetic testing at present, the risk to offspring in this situation cannot be clarified until the presence or absence of deafness in the first-born child is known. In dizygous twins, however, it is possible that only one twin or that both twins might be affected. Example 13 Example 13 shows the risks for one, or both, being affected by an autosomal recessive disorder when the zygosity is known (dizygous) or unknown. When zygosity is unknown the risks are calculated using the relative frequencies of monozygosity (1/3) and dizygosity (2/3). Calculation of risks is often complex and requires referral to a specialist genetic centre. Risks are determined by Exampe 14 Obligate combining information from pedigree structure and the results carrier of specific tests. If there is more than one affected male in a family, certain female relatives who are obligate carriers can be identified. Example 14 shows a pedigree identifying a number Obligate A of obligate and potential carriers, indicating the risks to several carrier 1/2 other female relatives. Examples 15 and 16 Since a carrier has a 50% chance of transmitting the condition to each of her sons, it follows that a woman who has several Obligate carrier unaffected but no affected sons is less likely to be a carrier. This 1/2 1/4 1/4 information can be used to modify a womans prior risk of Figure 8. Examples 15 and 16 indicate how the carrier risk for individual A from example 14 can be reduced if she has one unaffected son or four unaffected sons, without going into details of the actual calculation. A A 1/17 Example 17 1/3 In lethal X linked recessive disorders new mutations account for a third of all cases. When there is only one affected boy in a family, his mother is therefore not always a carrier. Carrier risks in families with an isolated case of such a disorder (for example Duchenne muscular dystrophy) are shown in example 17. These risks can be modified by molecular analysis if the 1/6 1/34 underlying mutation in the affected boy can be identified, or by Figure 8. Gonadal Example 17 mosaicism is common in the mothers of isolated cases of Duchenne muscular dystrophy, occurring in around 20% of 1/3 mothers whose somatic cells show no gene mutation, so that recurrence risk is not negligible. Isolated cases 2/3 1/6 Example 18 Pedigrees showing only one affected person are the type most commonly encountered in clinical practice, since many cases present after the first affected family member is diagnosed (as in example 18). Various causes must be considered, and risk estimation in this situation depends entirely on reaching an 1/3 1/12 accurate diagnosis in the affected person. In other cases, probabilities calculated from pedigree data cannot be made more certain. There are several explanations to account for isolated cases of an autosomal dominant disorder. Recurrence risks are negligible unless one parent is a non-penetrant gene carrier or has a mutation restricted to germline cells. Autosomal and X linked recessive disorders usually present after the birth of the first affected child. The recurrence risks for most chromosomal disorders are low, the exception being those due to a balanced chromosome rearrangement in one parent (see chapters 4 and 5). Studies documenting recurrence in the families of affected individuals provide data on which to base empiric recurrence risks. In isolated cases of severe congenital deafness, for example, it is estimated that Example 19 70% of cases are genetic, once known environmental causes have been excluded. The calculation of recurrence risk after an isolated case of severe congenital deafness is shown in example 20. In recessive disorders gene carriers remain unaffected, but in late onset dominant conditions, gene carriers will be Obligate carriers* destined to develop the condition themselves at some stage. Autosomal recessive gene mutations are extremely common and everyone carries at least one gene for a recessive disorder and one or more that would be lethal in the homozygous state. Autosomal dominant However, an autosomal recessive gene transmitted to offspring will be of consequence only if the other parent is also a carrier Person with affected * and transmits a mutant gene as well. Whenever dominant or parent and child X linked recessive gene mutations are transmitted, however, the offspring will be affected. The term carrier is generally restricted to people at risk of transmitting mendelian disorders and does not apply to parents * * whose children have chromosomal abnormalities such as Down Autosomal recessive syndrome or congenital malformations such as neural tube defects. An exception is that people who have balanced Parents and child chromosomal translocations are referred to as carriers, as the (children) of inheritance of balanced or unbalanced translocations follows affected person mendelian principles. These obligate carriers can be identified by drawing a affected sons or family pedigree and they do not require testing as their genetic one affected son and another state is not in doubt. Obligate carriers of autosomal dominant, * affected male autosomal recessive and X linked disorders are shown in the box. When direct mutation analysis is not possible, information is needed regarding the proportion of obligate carriers who show abnormalities on clinical examination or with specific investigations, to enable All daughters of interpretation of carrier test results in possible carriers. In late an affected man onset autosomal dominant disorders it is also important to know at what age obligate carriers develop signs of the condition so that appropriate advice can be given to relatives at risk. Occasionally, *Indicated or feasible in families with an affected member heterozygous subjects may show minor abnormalities, such as altered red cell morphology in sickle cell disease and mild anaemia in thalassaemia. New mutations and uniparental disomy are 1 2 3 very rare exceptions where a child is affected when only one Control parent is a carrier. The parents of an affected child do not bands need testing unless this is to determine the underlying mutation to allow prenatal diagnosis when there are no surviving affected children. For the healthy siblings and other relatives of an affected Deletion band Normal band person, carrier testing for themselves and their partners is only appropriate if the condition is fairly common or they are consanguineous. Testing for carrier state in the relatives of an individual with an autosomal recessive disorder is referred to as cascade screening. If the child has two different mutations, the parents are tested to see which mutation they each carry. For those shown to be carriers, their partners can then be and normal bands tested. If no indicating the absence of the F508 mutation mutation is detected, their carrier risk can be reduced from their 1 in 25 population risk to a very low level, although not absolutely excluded. In this situation, the risk of cystic fibrosis affecting future offspring is very small and prenatal diagnosis is not indicated. The main reason for offering cascade screening is to identify couples where both partners are carriers before Box 9. In these cases, prenatal diagnosis is carrier detection both feasible and appropriate. Genetic counselling cannot be undertaken without accurate assessment of carrier state, and calculating risks is often complex. In families with more than one affected male, obligate new mutation carriers can be identified and prior risks to other female relatives or gonadal mosaicism calculated. A variety of tests can then be used to determine carrier state and to undertake prenatal diagnosis. In families with new mutation only one affected male, the situation regarding genetic risk is more complex, because of the possibility of new mutation.

Sentinel node biopsy is proven efective at staging the axilla for positive lymph nodes and is proven to have fewer short and long term side efects, 1 and in particular is associated with a markedly lower risk of lymphedema (permanent arm swelling). When the sentinel lymph node(s) are negative for cancer, no axillary dissection should be performed. When one or two sentinel nodes are involved with cancer that is not extensive in the node, the patient received breast conserving surgery and is planning to receive whole breast radiation and stage appropriate systemic therapy, axillary node dissection should not be performed. However, the signifcance of radiation exposure as well as costs associated with these studies must be considered, especially in patients with low energy mechanisms of injury and absent physical examination fndings consistent with major trauma. Avoid colorectal cancer screening tests on asymptomatic patients with a life expectancy of less than 10 years and no family or personal history of colorectal neoplasia. Screening for colorectal cancer has been shown to reduce the mortality associated with this common disease; colonoscopy provides the opportunity to detect and remove adenomatous polyps, the precursor lesion to many cancers, thereby reducing the incidence of the disease later in life. The risk/beneft ratio of colorectal cancer screening or surveillance for any patient should be individualized based on the results of previous screening examinations, family history, predicted risk of the intervention, life expectancy and patient preference. Avoid admission or preoperative chest X rays for ambulatory patients with unremarkable history and physical exam.

Five Things Dentists and Patients Should Question Dont recommend non-fuoride toothpaste for infants and children. The beneft of fuoride-containing toothpaste arises from its topical efect on dental enamel by interrupting enamel demineralization caused by 1 bacterial acids and enhancing remineralization of the enamel surface. Anti-caries (anti-cavities) beneft begins with eruption of the frst primary tooth. Use of recommended amounts of fuoride toothpaste minimize risks of fuorosis, a whitish discoloration of enamel. Avoid restorative treatment as a frst line of treatment in incipient (non-cavitated) occlusal caries without frst considering sealant use. High quality evidence shows sealants are safe and efective in arresting caries progression in initial stage (incipient) non-cavitated, occlusal caries. Applying sealants as soon as initial stage caries is detected can improve outcomes by minimizing the later need for more extensive restorative care. Avoid protective stabilization, sedation or general anesthesia in pediatric patients without consideration of all options with the legal guardian. Some children do not respond to communicative behavior guidance techniques and require treatment of dental disease. Advanced behavior guidance 3 techniques of sedation, protective stabilization, and general anesthesia ofer risks and benefts often beyond the health knowledge of parents and other caretakers. Informed consent best practice requires a thorough, understandable explanation of these techniques and alternatives including deferral of treatment with its inherent risks. Avoid routinely using irreversible surgical procedures such as braces, occlusal equilibration and restorations as the frst treatment of choice in the management of temporomandibular joint disorders. Therefore, management is generally conservative and includes reversible strategies such as patient education, medications, physical therapy and/or the use of occlusal appliances that do not alter the shape or position of the teeth or the alignment of the jaws. Dental restorations (fllings) fail due to excessive wear, fracture of material or tooth, loss of retention, or recurrent decay. The larger the size of the 5 restoration and/or the greater the number of surfaces flled increases the likelihood of failure. Restorative materials have diferent survival rates and fail for diferent reasons, but age should not be used as a failure criteria. Patients with any specifc questions about the items on this list or their individual situation should consult their dentist. The Steering Committee reviewed critical issues in dentistry to identify potential recommendation topics and developed, through an evidence-based process, a list of recommendation statements with supporting scientifc evidence. Via an intense consensus process, the Steering Committee prepared a list of recommendation statements which were sent to the Council on Access, Prevention and Interprofessional Relations for review.

The main identifable risk associated with reducing or discontinuing acid suppression therapy is an increased symptom burden. It follows that the decision regarding the need for (and dosage of) maintenance therapy is driven by the impact of those residual symptoms on the patients quality of life rather than as a disease control measure. Do not repeat colorectal cancer screening (by any method) in average risk individuals for 10 years after a high-quality colonoscopy that does not detect neoplasia. Published studies indicate the risk of cancer is low for 10 years after a high-quality colonoscopy fails to detect neoplasia in this population. Therefore, following a high-quality colonoscopy that does not detect neoplasia, the next interval for any colorectal screening should be 10 years following that normal colonoscopy. Do not repeat surveillance colonoscopy for at least fve years for average-risk patients who have one or two small (<1cm) adenomatous polyps, without high-grade dysplasia or villous histology, completely 3 removed via a high-quality colonoscopy. The timing of a follow-up surveillance colonoscopy should be determined based on the results of a previous high-quality colonoscopy. Evidence based (published) guidelines provide recommendations that patients with one or two small tubular adenomas with low grade dysplasia have surveillance colonoscopy fve to 10 years after initial polypectomy. In patients with Barretts esophagus without dysplasia (cellular changes) the risk of cancer is very low. In these patients, it is appropriate and safe to exam the esophagus and check for dysplasia no more often than every three years because if these cellular changes occur, they do so very slowly.

American Geriatrics Society Ten Things Clinicians and Patients Should Question Dont recommend percutaneous feeding tubes in patients with advanced dementia; instead ofer oral assisted feeding. Tube feeding is associated with agitation, increased use of physical and chemical restraints and worsening pressure ulcers. Dont use antipsychotics as the frst choice to treat behavioral and psychological symptoms of dementia. People with dementia often exhibit aggression, resistance to care and other challenging or disruptive behaviors. In such instances, antipsychotic 2 medicines are often prescribed, but they provide limited and inconsistent benefts, while posing risks, including over sedation, cognitive worsening and increased likelihood of falls, strokes and mortality. Use of these drugs in patients with dementia should be limited to cases where non-pharmacologic measures have failed and patients pose an imminent threat to themselves or others. Identifying and addressing causes of behavior change can make drug treatment unnecessary. There is no evidence that using medications to achieve tight glycemic control in most older adults with type 2 diabetes is benefcial. Among non-older adults, except for long-term reductions in myocardial infarction and mortality with metformin, using medications to achieve glycated 3 hemoglobin levels less than 7% is associated with harms, including higher mortality rates. Tight control has been consistently shown to produce higher rates of hypoglycemia in older adults.

Based on surveys conducted between 2002 and 2004, 54% of New York State third-graders had experienced tooth decay, while 33% were found to have untreated dental caries at the time of the survey. In 2004, 44% of New York State adults between 35 and 44 years of age had lost at least one tooth to dental decay or as a result of periodontal disease and 17% of New Yorkers between 65 and 74 years of age had lost all of their permanent teeth. More than 12 million New Yorkers receive fluoridated water, with 73% of the population on public water systems receiving optimally fluoridated water in 2004. The percent of the States population on fluoridated water was 100% in New York City and 46% in Upstate New York. Counties with large proportions of the population not covered by fluoridation are Nassau, Suffolk, Rockland, Ulster, Albany, Oneida, and Tompkins. The Program targets children in fluoride deficient areas residing in Upstate New York communities not presently covered by a fluoridated public water system and is comprised of a school-based Fluoride Mouth Rinse Program for elementary school children and a Preschool Fluoride Tablet Program for 3-5 year olds in Head Start Centers and migrant childcare centers. In 2004, 115,000 children participated in the fluoride mouth rinse program and 6,000 children received fluoride supplements as either tablets or drops. The Bureau of Dental Health, in collaboration with the New York State Department of Healths Bureau of Water Supply Protection, monitors the quality of fluoridation services statewide. Additionally, technical assistance is provided to communities interested in implementing water fluoridation.

Dental sealants are a plastic material placed on the pits and fissures of the chewing surfaces of teeth; sealants cover up to 90 percent of the places where decay occurs in school childrens 4 teeth. Sealants prevent tooth decay by creating a barrier between a tooth and decay-causing bacteria. Sealants also stop cavities from growing and can prevent the need for expensive 2 fillings. According to the Surgeon Generals 2000 report on oral health, sealants have been shown to reduce decay 1 by more than 70 percent. The combination of sealants and fluoride has the potential to nearly 5 eliminate tooth decay in school age children. Sealants are most cost-effective when provided to 6 children who are at highest risk for tooth decay.

With Program 68% Use of dental services (dental visit during the prior Without Program 33% year) by Medicaid-eligible children and children enrolled in Child Health Plus was limited to 4 to 21 year olds with continuous enrollment during the year. Because children younger than 4 years of age and those without continuous enrollment have fewer opportunities to use dental services, it is customary to assess dental visits among 4 to 21 year old continuous enrollees. The prevalence of decay is measured through an assessment of caries experience (have ever had decay and now have fillings), untreated Access to Dental Care by Family decay (active unfilled cavities), and urgent care Income New York State: 2003 (reported pain or a significant dental infection that 90 requires immediate care). Although dental caries is preventable, many children unnecessarily suffer the consequences because of poor oral care and the inability to access preventive 60 and treatment services in a timely manner.
