At the in-person taskforce meeting thyroid symptoms memory loss order levothroid 50mcg with amex, each primary reviewer presented the recommendation and evidence grade for the key question with a summary of the supporting evidence thyroid disease in dogs levothroid 100 mcg low cost. Discussion ensued until the taskforce achieved consensus thyroid cancer familial discount levothroid 100mcg without prescription, defined as at least 6 of the 8 members agreeing on the recommendation as strong or weak thyroid quizlet order cheap levothroid. Notes were kept of each discussion zinc thyroid gland order levothroid 200 mcg overnight delivery, such that major dissenting opinion(s) could be included in the guidelines thyroid symptoms complete list best purchase for levothroid, which were written based on the results of the taskforce meeting. Further deliberation occurred after the attended meeting via phone conferences and email to determine the final recommendations. Guiding principles Prior to review of the published evidence, the taskforce created a set of guiding principles to standardize the approach across individual reviewers that was approved by all reviewers. In the absence of data on adult height, surrogate short-term outcomes such as growth velocity, change in height z-score, or change in predicted height were considered, but did not form the basis of a recommendation. This is because the short-term 15 outcomes are dynamic and do not reliably predict adult height for many children; wide individual variability exists within the heterogeneous treatment population, and outcomes such as change in predicted adult height vary markedly depending on the methodology used [6]. The taskforce values and preferences were consistent in that harm prevention was the utmost factor in formulating strength of recommendation. Recommendations in this document were made using the existing literature; future studies may provide evidence that contradict or support the recommendations. Therefore, the taskforce suggests that the recommendations be applied in clinical practice with consideration of the evolving literature and the risks and benefits to each individual patient. Registries are limited by the fact that the enrolled population is vastly heterogeneous and limited to those patients who consent to enrollment. In the prospective, uncontrolled study of Shulman et al, [24], 10 pre-pubertal children (mean age 5. Left ventricular systolic and diastolic function did not change after 2 years of treatment. However, in another study, subtle alterations in left ventricular systolic function were noted [28]. Most of these studies involved small cohorts of children, between 12 to 158 patients. While it is possible that combining tests might yield different results from tests performed on separate days, there is no evidence against performing both tests sequentially on the same day. Unlike adults, obesity dependent modifications to diagnostic criteria in children are undetermined. However, there is no controlled, evidence-based gold standard for this cut-off, which was adopted for identifying partial cases in the continuum between complete deficiency and normal. In the absence of evidence from controlled studies, post-marketing surveys might help estimate how levels within this continuum predict response to treatment. Adult height analyses from the post marketing studies are not available and would not be meaningful because of a strong bias to continue treatment only in good early responders. These results also suggested imperfect reproducibility of the same test in the same patient, with the highest correlation, that being for duplicate testing with insulin stimulation, having a coefficient of only 0. Normal values were established using polyclonal radioimmunoassays and purified pituitary standards. Therefore, standardization or, at least, harmonization is required to meaningfully evaluate and compare results. If different methods give the same result for the same serum pools, the assays can be considered standardized. If not, harmonization is achieved by 23 documenting sample-independent differences and deriving correction factors to obtain the same values for the same sample, by the use of commutable serum pools as recently outlined by Ross, et al. Using three reference assays (two using the same standard, 88/624), Hauffa, et al. In another study, samples from 47 provocative tests were assayed with four different methods [67]. A systematic, multi laboratory effort at standardization of assays in Finland between 1998-2003 showed considerable improvement in concordance, but even in the last year of the effort, discrepancies persisted [68]. Another harmonization effort in Germany found a 27% misclassification rate before adjusting results by a conversion factor [69]. Technical remark: A reasonable approach in both boys and girls would be 2 mg (1 mg for body weight <20 kg) of -estradiol (not ethinyl estradiol) orally on each of the two evenings preceding the test. Alternatively, boys can be primed with intramuscular testosterone (50-100 mg of a depot formulation administered 1 week before the test). In children with constitutional delay of growth and puberty, the normal decline in pre-pubertal growth velocity with age (interrupted by the pubertal growth spurt) is prolonged and may lead to frankly 24 abnormal growth velocity [71]. An observational study reported adult height in 50 otherwise healthy boys evaluated for short stature with delayed puberty (mean delay of 2 years) and growth velocity <5 cm/yr. However, there were no data on females, and most of the boys had a normal adult height prediction at the time of testing (mean -1. No gynecomastia in boys or other side effects have been reported with the recommended doses of sex steroid priming. No systematic controlled evidence exists to favor any of the proposed protocols over another. In addition to first-year acceleration of height velocity being a very imperfect predictor of adult height gain, a major weakness of this study was that four of the seven patients were of pubertal age with severe bone age delay. Onset of puberty during treatment was not evaluated and could account for much or all of this acceleration. A similar first-year growth acceleration was reported in two other studies of children diagnosed by the same criteria [79-81], and both of these studies suffered from the same limitations. Studies directly comparing different dose regimens enrolled small numbers of patients and results differed between studies. As one of its guiding principles, the guidelines taskforce endorses harm prevention (theoretical or proven) over practices that have unproven benefits. Models have been verified retrospectively in two different cohorts of less than 100 children [56]. Although logical and promising, these strategies to optimize growth parameters in the short term have not been tested to adult height. Additionally, the comparative effectiveness of these various strategies has not been tested. However, the complex interactions among the three proteins have not been studied sufficiently to support using alternative markers. The absolute difference in mean adult height between the high dose and control dose (0. Of the 97 subjects enrolled, 10 experienced serious adverse events, 4 in the standard dose group and 6 in the high dose group. Although no cases of intracranial hypertension or slipped capped femoral epiphysis were reported, the study was not adequately powered to detect these potential serious side effects. Definition by bone age also varied across studies, with 14-15 years used for girls and 16-17 years used for boys. There have been no studies comparing adult height in persons in whom therapy was deemed complete at a certain growth rate versus a certain bone age. The size and duration of these post-marketing studies provides reassurance that on-treatment adverse events that are either frequent or have catastrophic consequences, are not being missed. A referral for formal funduscopic examination by an ophthalmologist is advised if symptoms suggestive of intracranial hypertension occur such as severe headache, double/blurry vision, and vomiting. Routine monitoring for suggestive symptoms such as hip and/or knee pain and changes in gait is advised and, if positive, careful physical examination and consideration of imaging and orthopedic specialty consultation. We recommend informing at-risk patients about available data and encourage long-term follow up with their oncologist. We recommend shared decision-making that involves the patient, family, oncologist, and treating endocrinologist. For children considered not to be at risk, we recommend that counseling includes information about the unknown long-term. The transition period is the time from late puberty to establishment of adult muscle and bone composition, and encompasses attainment of adult height. Persons with small pituitary glands at diagnosis have a high rate of testing normal when retested after completion of growth [164,171] thus a small pituitary is not considered a structural defect. This suggests a need for more studies to determine the frequency and best practices for the re-assessment of these patients over time. Glucagon stimulation testing is a promising alternative for provocative testing in adults [183,184], but has not been specifically tested in the transition period. The optimal dose to achieve the 42 desired metabolic effects in young adults is not established. Females receiving oral estrogen (but not transdermal) may need higher doses than other patients. The decision can be made on a case by-case basis after assessment of physical and psychological burdens, and discussion of risks and benefits. Additionally, the data for the untreated control group were historical data from 9 different published studies [201]. Models utilizing the first year change in growth rate may assist in predicting longer term response [202,203]. Additionally, patients should be monitored for changes in psychological functioning and quality of life; better clinical tools for these outcomes need to be developed and validated for this patient population. Only one study of dose effect, that of Albertsson-Wikland et al [198], included an untreated control group (see section 3. Total gain in height seems to correlate with first-year responsiveness, while bone age delay may [198] or may not be predictive [111,202]. The actual increase in annualized growth velocity that results in a gain in height relative to age and gender is dependent on age; younger pre pubertal and pubertal children grow faster than older pre-pubertal children. To date, there is no consensus as to what comprises an adequate short-term first year growth response [209]. Additional characteristic features, such as microcephaly, protruding forehead, saddle nose, small chin, and high-pitched voice, may raise clinical suspicion [212,217]. Additionally, discordant results were obtained when the test was repeated in the same subjects using the same laboratory [224]. Genetic testing is desirable for individuals for whom diagnostic uncertainty is problematic, in order to better direct treatment. Similar short-term outcomes were seen with 80 and 120 mcg, but published studies had limitations and there is no strong evidence supporting superiority of one dose over the other. Tabulations of data, usually as growth velocity by year on treatment by study, can be found in several papers [217,237,243,244]. However, the once-daily approach is still followed by some, claiming similar growth velocities and fewer side effects [243,246]. While authors have used comparisons across studies to support their preferred dosing regimen, this approach is fraught with limitations that preclude determination of definitive recommendations. While some patients embedded within several studies reached adult height, the effect of dosing on adult height was not studied systematically. Puberty was a potential confounder in two ways: some patients also received 50 gonadotropin-releasing hormone agonist therapy, and many reached puberty within their respective studies. Despite this, Tanner staging was not reported even though the primary outcome was growth velocity. As stated in the guiding principles of this document, harm prevention was accorded the utmost importance in formulating the recommendations. These short-term results suggest that the higher dose not only costs more, but may compromise adult height gains via accelerated skeletal maturation. Although most episodes were mild or moderate, severe hypoglycemic reactions including loss of consciousness and seizure also have occurred. For these children, even a small increase in adult height may be a considerable benefit. Growth hormone treatment poses some possible serious long-term adverse events that are not acceptable risks in a healthy child with normal adult height potential. Conclusions and future directions Careful review of the existing evidence revealed gaps in the knowledge base and areas open for future clinical investigation and treatment guideline development. The lack of tight correlation between short-term and long-term outcomes downgraded the reliability of such studies in accordance with the rigorous methodologies used in the creation of this document. At the same time, while adult height and other long-term outcomes are the benchmarks to be sought, we must acknowledge the logistical and cost challenges in conducting such long-term studies prospectively and the difficulties in correctly categorizing subjects and treatments in such long-term studies retrospectively. Beyond duration of follow-up, the current knowledge base contains gaps that impede the clear definition and hence delivery of what is considered good clinical care. Genetic testing is expected to expand and offer additional insights, and elucidation of markers for therapeutic responsiveness may help guide clinical decisions. In order to define quality care, complementing the need for better diagnostics is the need for better outcome metrics. More reasoned and uniform therapeutic goals will aid in determining the appropriate end-points for treatment clinically [263] and increase consistency across future research studies. No treatment at all is also a very reasonable option, given that short stature per se is not a disease, and the relationship between adult height and adult quality of life is weak and poorly understood. Psychological counseling should always be offered for patients suffering due to their stature, either in addition to or instead of hormone treatment as appropriate, although the efficacy of counseling for short stature has not been rigorously evaluated.

The likely source of the eggs are ectopic adult worms either living in veins around the cord or by retrograde fow of eggs through valveless spinal veins in connection with the iliac veins thyroid gland treatment order 100 mcg levothroid fast delivery. The time between exposure and onset of the paraplegia is usually weeks to months and rarely years thyroid symptoms-raspy voice generic 200mcg levothroid free shipping.

A positive serological test is useful in non endemic patients as an indicator of previous exposure thyroid symptoms tingling tongue buy levothroid 100mcg with mastercard. The prognosis is guarded, with about 10% mortality, 30% remaining permanently paraplegic and 60% showing moderate to good recovery. It is estimated that neurological involvement will occur in about 7% of patients 10-25 years after primary infection, if primary syphilis is untreated. However despite the frequency of primary syphilis in Africa, neurosyphilis remains uncommon in many countries there. However tabes dorsalis remains a distinctly uncommon clinical presentation in Africa. It occurs predominantly in females in their late teens or early 20s in Africa but may afect older women in their 30s and 40s in high income countries. The main spinal fndings are those of a myelopathy with brisk knee refexes and up going plantars. Tese typically occur in combination with signs of neuropathy, including absent ankle jerks and loss of peripheral sensation including joint position sense. The dose is 1 mg on alternate days for a total of fve injections followed by 1 mg injections every 3 months for life. If intramuscular injections are not available then B-12 can sometimes be given orally, in a dose of 1 mg po daily. William Howlett Neurology in Africa 245 Chapter 10 paraplegia non traumatiC this may provide adequate replacement particularly in cases secondary to nutritional or dietary defciency. Tese disorders represent a distinct group of community based myeloneuropathies which result in paraplegia. Epidemics have been known to occur in cassava growing of the former Belgian Congo as far back as 1928 and possibly earlier. In epidemics as many as 1-30/1000 persons are afected, mainly growing children and fertile women. Aetiology The cause of konzo has been attributed to the combined efect of months of high cyanide and low protein (methionine and cysteine, sulphur based amino acids) intake from exclusive consumption of insufciently processed bitter cassava (Fig. The bitter cassava grow well in poor soils but contain increasing amounts of cyanogenic glycosides mainly linamarin. Processing disrupts the root tissue and releases volatile hydrogen cyanide and this makes the food safe for human consumption. Safe processing takes days in the case of hydrolysis and fermentation, to weeks for sun drying. Clinical features The clinical features are characterized by an abrupt (usually <24 hours) onset of a permanent but non progressive spastic paraplegia (Figs. Supportive investigations include elevated blood or urine thiocyanate levels and low levels of the essential amino acids methionine and cysteine. Prevention is mainly directed at growing cassava with lower cyanide content and public education concerning safer methods of cassava processing. Surgical treatment involving Achilles tendon lengthening operations have proved successful in increasing mobility in some patients. In Africa it is found only in parts of North Western Ethiopia where the grass pea is widely grown and consumed. The association of paraplegia with grass pea consumption was already recognized in ancient Greece. However, they are distinguishable from each other because they both occur in geographically distinct areas which do not overlap. Treatment and prevention The management and prevention are along the same principles as that for konzo. The disease is characterized by a combination of gradual onset in older adults of peripheral neuropathy, sensory ataxia, optic neuritis, deafness and sometimes spastic paraplegia. This task should be entrusted to a family carer or carried out by the nursing staf. Attention early to adequate nutrition and measures to prevent infection are also very important. If bed sores do become established they require vigorous cleaning, surgical debridement and possible skin grafting. This typically occurs during the frst days of an acute paraplegia and persists particularly in patients with faccid paraplegia. Loss of control of bladder function or neurogenic bladder arises because of lesions situated in either the spinal cord or cauda equina. Patients with a cauda equina lesion and faccid paraplegia usually require permanent catheters. Constipation is a feature of both faccid and spastic paraplegia with the bowels opening every week or less often. Measures to prevent it include satisfactory fuid intake, adequate fbre/bulk in the diet, and the early use of laxatives usually the combination of a lubricant and an irritant. This helps to prevent thrombosis, joint stifness, spasticity and contractures, and to exercise the non afected muscles. The starting dose of baclofen is 5 mg twice daily increasing slowly over weeks to 20-40 mg twice daily as required. The starting dose of diazepam is 2-5 mg three times daily, increasing to a maximum of 20 mg three times daily. In a medical setting, this is usually provided by medical staf including nurses, doctors, physiotherapists, occupational therapists and carers. The patient needs to train to strengthen the non paralysed muscles and family members need to be instructed and trained to regularly passively move paralysed limbs in order to prevent contractures and bed sores. A routine of avoiding prolonged periods of weight bearing will need to be established and maintained. This is helped by the person regularly taking the weight of the body of the seat of chair or wheelchair a couple of times every hour and by using protective cushions to guard against pressure points. Regular inspection of skin is essential and may of necessity have to be carried out by the carer. Bladder and bowels The patient needs training in refex bladder emptying, condom drainage, intermittent self catheterization, indwelling catheter management, anticholinergic drugs and early recognition and treatment of urinary tract infections. The patient needs a healthy wholesome and regular diet with laxatives and suppositories to avoid constipation. Sex and fertility this needs to be discussed and explained with the patient and partner. In female patients local spasticity in the thigh adductors may be helped by local antispasmodic injections or medications. This needs to be explained clearly to the patient in order to avoid excessive weight gain. Uptake of wetting method in Africa to reduce cyanide poisoning and konzo from cassava.

The student should aim to be able to recognize the diferent types of neuropathies and know their main causes and management. Pathophysiology Peripheral nerves are made up of multiple axons surrounded by myelin, Schwann cells and their covering sheaths. In neuropathies the nerves may be damaged at three main sites: the axon, the myelin and the cell body. This is the most common form of peripheral neuropathy and usually afects sensation greater than power and has a mainly distal distribution. This afects power more than sensation and the weakness is usually proximal as well as distal. A misplaced injection in the buttocks in young children is the main cause of sciatic nerve injury in Africa. Leprosy is a common cause of both mononeuropathy and mononeuritis multiplex in Africa. The main clinical features of the most common focal nerve lesions are outlined in Table 11. However, in clinical practice these signs, although useful when present are unreliable when absent. Treatment is by local injection of steroids, wearing a night time wrist splint or by surgical decompression if necessary Typical wasting of thenar muscles Figure 11. This results in dyasthesia/paraesthesia and sensory impairment/loss in the distribution of the little fnger and adjacent half of the ring fnger and ulnar aspect of the hand front and back. Tere is wasting and weakness of the intrinsic muscles of the hand and the deep fexors of the 4th and 5th fnger with sparing of the thenar muscles (Figs. This gives rise to the characteristic claw hand deformity seen in chronic ulnar lesions. Compression results in wrist drop with weakness of the fnger and wrist extension and sometimes a small patch of sensory loss on the dorsum of the hand and web of the thumb (Fig. Sciatic nerve injury most commonly occurs as a result of a misplaced injection in the buttocks in early childhood. It is responsible for the following movements, hip extension, knee fexion and ankle plantar and dorsifexion. Clinically, they are classifed as acute or chronic, motor or sensory or mixed and also autonomic. Neurological examination usually reveals wasting, fasciculation, distal weakness with absent refexes and loss of light touch. Motor symptoms include mild to severe weakness in the limbs, problems with walking or running, and difculties manipulating or using fngers and hands. Terms used to describe the superfcial sensory symptoms include: paraesthesia, meaning abnormal tingling sensation; hyperaesthesia, meaning increased sensitivity to a stimulus and dysaesthesia, meaning unpleasant tingling. Sensory symptoms tend to occur before motor symptoms and typically involve the feet earlier than hands. Findings on neurological examination include loss of light touch, pain and joint position sense distally in the limbs mostly the feet. Polymyositis and myopathy may sometimes mimic a neuropathy but skin involvement and the mainly proximal pattern of weakness should suggest underlying muscle disease. Fatigability after exercise, a mainly truncal-axial pattern of weakness, ptosis and intact refexes all point to myasthenia gravis. While myelopathy symptoms may sometimes mimic neuropathy, the predominantly upper motor neurone signs, the sphincteric involvement and pattern of sensory loss or alteration should all suggest spinal cord involvement. Diagnosis The diagnosis of peripheral neuropathy relies mainly on the clinical fndings and in as many as half the cases no underlying cause is found. High dose corticosteroids are used in neuropathies complicating vasculitis and chronic infammation. General measures include analgesics, anti infammatories, tricyclics, the antiepileptic drugs carbamazepine, pregabalin and gabapentin and also opiates (Chapter 20). Power is usually maintained but may very occasionally be decreased around the ankle joint. Sensation involving touch is mostly intact but touch is characteristically perceived by the patient as painful or dysaesthetic, particularly when touched crudely on the soles of the feet and the palms of the hands. Symptomatic relief of pain may be obtained using simple analgesics and/or amitriptyline; however opiates may be necessary in severe cases. In particular this occurs with the use of the nucleoside reverse transcriptase inhibitor, stavudine (d4T). Care should be taken to ensure that pyridoxine 20 mg/po/daily has been prescribed in all patients taking isoniazid, and that thiamine 100 mg/ po/daily should be given in suspected cases of B-1 vitamin defciency. It causes damage to nerves which results in characteristic deformity and disability. The average incubation of contracting the disease from contact household cases is estimated to be about 5 years. The main clinical presentations are anaesthetic skin lesions and peripheral neuropathy. Tese are macular or plaque-like hypoanaesthetic patches often with loss of sweating and occurring usually on the trunk (Fig. In lepromatous leprosy there are multiple, widespread, symmetrical, hypopigmented lesions with mostly intact sensation and/or infltrated patches, papules and nodules. The common sites are the greater auricular in the neck, the ulnar at the elbow, median at the wrist, Great radial cutaneous at the wrist, common peroneal at the Auricular knee and posterior tibial behind the medial malleolus Median (Figs.

Most is used as a protein source for high production dairy cattle and for feed lot cattle thyroid symptoms urine purchase levothroid cheap. This is not completely reassuring, however, because the sur veillance program has a potential flaw; the only two risk categories of cows sampled are rabies-suspect cattle that are rabies negative, and cattle over two years of age that have been given protein supplements for a good part of their diet and have developed signs of neurological disease. In conclusion, at a minimum, we believe the feeding of cows to cows should be discontinued, not expanded. Rifkin, a vege tarian activist, was the author of Beyond Beef, a critical expose of the global cattle industry. Other signers of the legal petition included several dairy farm ers and Virgil Hulse, a family physician and surgeon from Oregon. The proposed regulation was not published until August 1994, and by then it had already been scaled back con siderably. Both Rifkin and Hansen were calling for a ban on the practice of feeding rendered cows back to cows. The agency recognizes that the processed slaughter byprod ucts and 4-D [dead, dying, diseased, and disabled] adult sheep and goats have a long history of use in animal feeds without known adverse effects. How ever, the evidence for the development of a new pattern of disease transmis sion now indicates that these ingredients can no longer be categorically regarded as safe. Sheep producers could see themselves being offered up as sacrificial lambs and reacted accordingly. It therefore disagreed with the regulation and most of the underlying reason ing behind it. This scenario may also develop when the inevitable ques tion is asked about the safety of nerve tissue in the balance of the carcass when the brain and cord is suspect. Certainly it cannot be imagined that a dangerous agent exists in a three-year-old sheep due to infection acquired in utero or as a neonate, that does not exist in the animal at one year of age. This anomaly will not escape the attention of those dedicated to destroy ing the food-animal industry if this rulemaking proceeds. It would be more rational to counsel against the feeding of any product derived from a given species back to that species. There are also persons in other parts of the world who are consumers of our products, but who look for any excuse to disrupt trade on allegations such as appear in the notice. To use an inci dent to institute a broader feeding ban would cause severe disruption of the entire livestock industry which may not be justified. Beyond that simple point of agreement, however, most of the other allegations regarding Dr. Early in his career, Narang won recognition for his discovery that tubulo filamentous particles could be found in the brains of many animals infected with spongiform brain diseases. In the absence of government funding, Narang turned to Ken Bell, a busi nessman and philanthropist whose brother, a butcher, had died of a demen tia that Bell suspected was Creutzfeldt-Jakob Disease. However bizarre this story seemed, it took on a certain air of credibility in the politically polarized atmosphere surrounding mad cow disease. Other unusually young victims were also beginning to appear, some times with Narang at their bedsides. If his test was valid, there was something obviously unethical about withholding information that might help fight a killer disease. If his science was not valid, on the other hand, Narang had become the worst imaginable sort of ambulance-chaser, misleading the rela tives of sick victims by pretending that he and he alone held the key to under standing their tragedy. By 1994, the number of new cases was dropping dramatically, con firming the analysis of government scientists who had predicted that a ban on cannibalistic feeding practices would eventually eliminate the epidemic. He became depressed and dizzy, and his parents, David Apocalypse Cow 169 and Dorothy, watched him deteriorate into a living nightmare of madness and terrifying hallucinations. Sometimes when he reached for a cup he missed it, but carried on with the movement that would have taken it to his lips. I mentioned it to somebody, and then I dismissed it because it seemed a ridicu lous idea. Without giving his name, the report claimed that the body of a dead 19-year-old was being specially tested for a link to mad cow disease. They had two daughters, Natalie and Jacqueline, and she was in the early stages of her third pregnancy when she began suffering mood swings and memory loss. Michelle was seen by a psychologist, then admitted to Manchester Royal Infirmary, six months before she was due to give birth. Her son, Tony, was delivered prematurely by emergency caesarean section, shortly before she lapsed into a permanent coma. Doctors were unable to deter mine whether she had passed the disease on to her child. Jean Wake, a housewife and mother of a teenage girl, had also held a job that required her to handle beef, chopping up meat in a pie factory. Like the others, she suffer ing a lingering, painful decline until her death in November of 1995. The hospital agreed to provide the sample but refused to let him use their on-site facilities to do the testing. You say that the hospital caring for your daughter seems to be trying to stop a scientist investigating the cause of her illness. However, I understand from the hospital concerned that they are content for the scientist to have the samples that he has requested in order to carry out his tests but, as he is not employed by the hospital, he will have to perform the tests elsewhere. She had lived in Australia for 12 years, but doctors said she almost certainly contracted the disease in England. By October, her condition was so bad that her mother, Muriel Jones, flew out to Australia to help nurse her for the last six months of her life. At his funeral, gravediggers were issued protective clothing and surgical gloves and his grave was dug to a depth of nine feet instead of the usual six. The disease took two years to run its course, ending with her death in January 1996. Robert Will of Western General Hospital in Edinburgh, who chaired the surveillance unit, warned against jumping to conclusions, noting that other countries in Europe had also recorded more cases than usual during 1994. It was possible, he suggested, that more cases were being discovered due simply to increased surveillance rather than an actual increase in the disease. V V V As late as Christmas of 1994, Peter Hall had never suffered a serious ill ness and had rarely missed school. He was a promising student in his first year of college, majoring in environmental studies at Sunderland University. His mother, Frances, had also given up beef when the first alarming news stories appeared. Peter was looking scruffy, not eating, losing weight, becoming withdrawn and dark. Frances and Derek asked if it could be Creutzfeldt-Jakob Dis ease, but the neurologist insisted it was highly improbable in someone his age. The neurologist visited once a week, but the hospital was unable to offer any diagnosis or treatment. They con tacted Narang to have Peter tested, and in January of 1996 Narang reported that Peter had tested positive. In the space where the examiner was supposed to fill in the underlying cause of death, the doctor simply drew a question mark. On advice from the hospital, no viewing of his body was allowed and the coffin was kept closed. Informa tion is elicited on a quite extraordinary range of activities, from whether the deceased had ever been in contact with ferrets to whether he or she had pierced ears. Proving a definite association is a very diffi cult thing to do with a rare disease unless there is a major change. He complained of a pain in the back of his head and his mind was swimming all the time.
