[School hygiene in the past, present and future--in the opinion of the Inspector of Pediatrics and School Medicine and member of the European Society for Social Pediatrics (ESSOP)].

Yesterday. School hygiene acted in a clear way. Physician, pediatrician, nurse and hygienist were employed at school and were responsible for carrying out periodic examination, vaccination of school children and youth. They also supervised groups of children with posture defects, obesity, underweight, circulatory system and respiratory tract (asthma, anaphylaxis), diseases nervous system disorders and also propagated health education at school. Inspector of Pediatrics and School Medicine was in charge of School Medical Care. Today. Reform of the Public Health System. Medical examination and services have their value in money. A school physician, some hygienists and school nurses have been dismissed to decrease the financial costs of school hygiene. All medical services must be bought by the National Health Service. Public and private medical services at doctors and nurses are organized at schools. Each service performs examinations, vaccinations bought by the National Health Service or parents. A pupil is a subject of buying medical services. He may be vaccinated by a nurse but a medical examination must be either bought or performed by home doctor. The supervision of school children with different illnesses is not conducted by a school doctor. At present all the threats of contemporary world such as alcohol, tobacco, drug addiction, nervous system illnesses and allergies which are destructive for youth start when they are teenagers. School is an important place for carrying out on a large scale prophylactic services with medical teams of paediatricians, rehabilitation specialists and psychologists. Tomorrow. School Hygiene at School. Not at home doctor's. Recommendations, Daily Hygiene: personal, oral, food mental.... Hygiene of studying, rest and daily effort. Struggle with mass media, alcohol, drug, Internet, Computer addiction, violence, stupidity and poverty. School Hygiene should be adjusted to youth's health needs in accordance with the recommendations of European Society for Social Pediatrics (ESSOP) and Committee on Public Education, American Academy of Pediatrics and reinforced, it should not be eliminated.

Conceptual apraxia in probable Alzheimer's disease as demonstrated by the Florida Action Recall Test.

Patients with probable Alzheimer's disease (AD) often have difficulties associated with semantic knowledge. Therefore, conceptual apraxia, a defect of action semantics and mechanical knowledge, may be an early sign of this disease. The Florida Action Recall Test (FLART), developed to assess conceptual apraxia, consists of 45 line drawings of objects or scenes. The subject must imagine the proper tool to apply to each pictured object or scene and then pantomime its use. Twelve participants with Alzheimer's disease (NINCDS-ADRDA criteria) and 21 age- and education-matched controls were tested. Nine Alzheimer's disease participants scored below a 2-standard-deviation cutoff on conceptual accuracy, and the three who scored above the cutoff were beyond a 2-standard-deviation cutoff on completion time. The FLART appears to be a sensitive measure of conceptual apraxia in the early stages of Alzheimer's disease.

Treatment options for fecal incontinence.

PURPOSE: Fecal incontinence is a socially devastating disorder which affects at least 2.2 percent of community dwelling adults and 45 percent of nursing home residents. Most incontinent patients can be helped, but physicians are poorly informed about treatment options. The aim of this study was to develop a consensus on treatment options by convening a conference of surgeons, gastroenterologists, nurses, psychologists, and patient advocates. METHOD: A 1-1/2 day conference was held in April, 1999. Experts from different disciplines gave overviews, followed by extended discussions. Consensus statements were developed at the end of the conference. This summary statement was drafted, circulated to all participants, and revised based on their input. CONCLUSIONS: 1) Diarrhea is the most common aggravating factor for fecal incontinence, and antidiarrheal medications such as loperamide and diphenoxylate or bile acid binders may help. Fecal impaction, a common cause of fecal incontinence in children and elderly patients, responds to combinations of laxatives, education, and habit training in approximately 60 percent. These causes of fecal incontinence can usually be identified by history and physical examination alone. 2) In patients who fail medical management or have evidence of sphincter weakness, anorectal manometry and endoanal ultrasound are recommended as helpful in differentiating simple morphologic defects from afferent and efferent nerve injuries and from combined structural and neurologic injuries. 3) Biofeedback is a harmless and inexpensive treatment which benefits approximately 75 percent of patients but cures only about 50 percent. It may be most appropriate when there is neurologic injury (i.e., partial denervation), but it has been reported to also benefit incontinent patients with minor structural defects. 4) External anal sphincter plication with or without pelvic floor repair is indicated when there is a known, repairable structural defect without significant neurologic injury. It is effective in approximately 68 percent. 5) Salvage operations are reserved for patients who can not benefit from biofeedback or levator-sphincteroplasty. These include electrically stimulated gracilis muscle transpositions and colostomy. 6) Antegrade enemas delivered through stomas in the cecum or descending colon reduce or eliminate soiling in approximately 78 percent of children with myelomeningocele; this operation may come to be more widely applied. 7) Investigational treatments include implanted nerve stimulators, artificial sphincters, and anal plugs. 8) Patient characteristics which influence choice of treatment include mental status, mobility impairment, and typical bowel habits. 9) Additional research is needed to better define the mechanisms responsible for fecal incontinence, to assess the efficacy of these treatments, to develop better treatments for nursing home residents, and to identify predictors of outcome.

Surgically restoring portal blood flow to the liver in children with primary extrahepatic portal vein thrombosis improves fluid neurocognitive ability.

OBJECTIVES: Children with primary extrahepatic portal vein thrombosis (EHPVT) have portal-systemic shunting, which may lead to disturbed neurocognitive function similar to portal-systemic encephalopathy (PSE) seen with chronic liver disease and cirrhosis. The functions most affected are those involving fluid cognitive ability, which comprise neurocognitive domains such as attention, processing speed, and short-term memory, that are particularly vulnerable to systemic illness or diffuse neurologic insult. We determined the fluid cognitive ability of children with EHPVT and whether surgically restoring portal blood flow by mesenteric left portal vein bypass (MLPVB) improved it. DESIGN: Twelve children with EHPVT and no overt PSE underwent comprehensive neurocognitive testing before and 1 year after undergoing surgery with intent to perform MLPVB. The evaluations sampled 4 functional domains at both time points: (1) neurobehavioral (behavior, emotional, executive functioning); (2) broad cognitive (intelligence, achievement); (3) fluid ability (attention, mental speed, working memory, memory encoding); and (4) visual motor (drawing, fine motor). Tasks in the fluid-ability and visual-motor domains were expected to be especially sensitive to adverse effects of EHPVT and to be most likely to show improvement with MLPVB. The test group consisted of 8 subjects who underwent successful MLPVB, and the comparison group was composed of 3 patients who received distal splenorenal shunts and one whose MLPVB failed. RESULTS: Both groups demonstrated similar fluid cognitive ability at initial evaluation. Successful MLPVB resulted in significantly improved fluid cognitive function: in the fluid cognitive domain, significant improvements were seen for the hit reaction time variability in the Conner's Continuous Performance Test, the attention scale of the Cognitive Assessment System, and immediate verbal memory in the Children's Memory Scale. In the visual-motor domain, z scores on the Grooved Pegboard Test improved. No improvement was observed in the comparison group. DISCUSSION: The results show that surgically restoring portal flow to the liver in children with primary EHPVT results in improved fluid cognitive ability. Subjects showed some neurocognitive abnormalities involving mainly fluid cognitive ability consistent with minimal PSE seen in adults with chronic liver disease. Cognitive defects in patients with minimal PSE seem to relate primarily to attention and fine motor skill, and although affected patients can function in everyday life, they are at risk for performance deficits in educational and vocational situations requiring the ability to pay close attention and react quickly (eg, driving, employment in manufacturing). The tests we administered in these domains are pediatric equivalents to measures used to detect minimal PSE in adults and should detect abnormalities in the same functional domains. Our results suggest that a narrow battery of tests could be used to detect minimal PSE in children in a manner similar to the 5-test battery used in adults, eliminating the need for the comprehensive and broad testing we performed. Our findings suggest that shunting of portal blood from the liver in primary EHPVT can result in PSE and question whether it is as benign a disease as previously thought. The importance of our findings is twofold. For understanding the pathophysiology of PSE, we have shown that restoring blood flow to the liver improves cognitive function in children with EHPVT. For therapy for EHPVT, it becomes clear that MLPVB is an excellent treatment option. It is effective for treating the complications of portal hypertension and provides effective portal blood flow that other medical and surgical therapies do not. The findings provide additional evidence that primary EHPVT should be considered curable by MLPVB. However, comparison of overall risks and benefits of MLPVB with those of other therapeutic options and longer-term outcome studies must be completed before MLPVB can be fully endorsed as the best treatment for EHPVT in children. CONCLUSIONS: Surgical restoration of portal venous flow to the liver in children with primary EHPVT by MLPVB improves fluid cognitive ability. MLPVB should be considered in treating primary EHPVT, because it corrects portal blood flow and could optimize learning potential.

Sensorineural hearing loss in children and adults with Williams syndrome.

Williams syndrome (WS) is a genetic neurodevelopmental disorder, most often accompanied by mild-to-moderate mental retardation. Individuals with WS show unique communication strengths and impairments that are challenging to treat in community, educational, and vocational settings. Many issues regarding characteristics of auditory sensitivity in WS remain to be resolved. Our purpose was to obtain behavioral (screening and pure-tone audiometry) and objective (distortion product otoacoustic emission-DPOAE) measures of auditory system function from a group of 27 individuals with WS, 6-48 years of age. These measures were gathered both at an international professional conference (n = 19) and in a clinic setting (n = 8). In the behavioral screening conditions, 16/19 (84%) of the individuals failed the hearing screening; and in the behavioral diagnostic hearing condition, 6/8 (75%) demonstrated sensorineural hearing loss (SNHL) and 1/8 demonstrated a hearing loss of undetermined type. In the objective DPOAE testing, 19/25 (76%) had DPOAE absolute amplitudes below the 5th percentile for ears with normal hearing [Gorga et al. (1997); Ear Hear 18(6):440-455]. We report SNHL in 14/18 (78%) of school-age children with WS. Post hoc analyses revealed a significant effect for age, suggesting a pattern of progressive hearing loss. An effect size analysis indicated a clinically meaningful difference in the hearing sensitivity between school-aged children and adults in the high frequencies (4,000 and 8,000 Hz). Similar hearing loss phenotype was observed in patients with familial nonsyndromic supravalvular aortic stenosis (SVAS), suggesting that molecular defects in the elastin gene in the pathogenesis of SNHL in WS. This study highlights the importance of early and regular hearing testing for WS patients and suggests that elastin may have a previously unappreciated function in maintaining hearing sensitivity.

Sobering thoughts: town Hall meetings on fetal alcohol spectrum disorders.

Prenatal exposure to alcohol is one of the leading causes of preventable birth defects and developmental disabilities. During the past 30 years, fetal alcohol spectrum disorders (FASD), including fetal alcohol syndrome, have gradually begun to attract attention. However, awareness and understanding of the disorders remain low, and people who are affected are seriously underserved. The FASD Center for Excellence held a series of town hall meetings in 2002 and 2003 to gauge the issues surrounding FASD nationwide. On the basis of its findings, the center proposed a series of recommendations to begin to remedy some of the deficiencies that were identified.

Long-term abstinent alcoholics have normal memory.

It is generally believed that many non-Korsakoff alcoholics have subtle defects in memory. To determine whether such defects vary as a function of length of abstinence (LOA), we performed extensive memory testing with: (1) recently detoxified (n = 31; LOA-29 days); (2) intermediate-term abstinent (n = 28; LOA = 1.9 years); (3) long-term abstinent (n = 32; LOA-7.0 years) alcoholics; and (4) nonalcoholic controls (n = 37). All subjects were matched on age and education. Alcoholics were matched on years of alcoholic drinking. Memory measures were divided into the following domains: verbal learning, verbal recall, visual learning, visual recall, and paired associate learning. A series of MANOVAs were conducted that revealed a significant relationship between visual learning and length of abstinence, and a significant interaction between age and length of abstinence on visual recall. Long-term abstinent subjects were not significantly different from controls on any test. We conclude that memory disturbance demonstrable among recently detoxified alcoholics in the early weeks of their abstinence is not evident in demographically matched long-term abstinent alcoholics with similar drinking histories.

Washing our hands of the congenital cytomegalovirus disease epidemic.

BACKGROUND: Each year in the United States, an estimated 40,000 children are born with congenital cytomegalovirus (CMV) infection, causing an estimated 400 deaths and leaving approximately 8000 children with permanent disabilities such as hearing or vision loss, or mental retardation. More children are affected by serious CMV-related disabilities than by several better-known childhood maladies, including Down syndrome, fetal alcohol syndrome, and spina bifida. DISCUSSION: Congenital CMV is a prime target for prevention not only because of its substantial disease burden but also because the biology and epidemiology of CMV suggest that there are ways to reduce viral transmission. Because exposure to the saliva or urine of young children is a major cause of CMV infection among pregnant women, it is likely that good personal hygiene, especially hand-washing, can reduce the risk of CMV acquisition. Experts agree that such measures are likely to be efficacious (i.e., they will work if consistently followed) and the American College of Obstetricians and Gynecologists recommends that physicians counsel pregnant women about preventing CMV acquisition through careful attention to hygiene. However, because of concerns about effectiveness (i.e., Will women consistently follow hygienic practices as the result of interventions?), the medical and public health communities appear reluctant to embrace primary CMV prevention via improved hygienic practices, and educational interventions are rare. Current data on the effectiveness of such measures in preventing CMV infection are promising, but limited. There is strong evidence, however, that educational interventions can prevent other infectious diseases with similar transmission modes, suggesting that effective interventions can also be found for CMV. Until a CMV vaccine becomes available, effective educational interventions are needed to inform women about congenital CMV prevention. SUMMARY: Perhaps no single cause of birth defects and developmental disabilities in the United States currently provides greater opportunity for improved outcomes in more children than congenital CMV. Given the present state of knowledge, women deserve to be informed about how they can reduce their risk of CMV infection during pregnancy, and trials are needed to identify effective educational interventions.

Severity of cognitive impairment in juvenile and late-onset Huntington disease.

OBJECTIVES: To compare the severity of cognitive impairment among groups of patients with different age ranges at the onset of Huntington disease (HD) and to evaluate the variable influence of motor and cognitive deficits on functional disability across different ages at the onset of HD. DESIGN: Cross-sectional multidisciplinary evaluation of patients referred to our institution for care related to a possible diagnosis of HD. SETTING: The Huntington disease program in the Departments of Neurology and Genetics at the Fundación Jimenez Diaz, Madrid, Spain. PARTICIPANTS: Seventy-one patients with Huntington disease were classified into 3 groups depending on age at onset of motor symptoms: juvenile onset, 25 years of age or younger (group 1, n = 15); adult onset, from 26 to 50 years (group 2, n = 43); and late onset, 51 years or older (group 3, n = 13). Age- and education-matched controls (n=50) were included to compare cognitive performance with patients in groups 1 and 3. MEASURES: Cognitive evaluation encompassed a wide neuropsychological battery to assess global cognitive functioning and visuospatial, prefrontal, and memory functions. Clinical data included motor and functional variables measured by using the Unified Huntington's Disease Rating Scale. Genetic analysis determined the number of CAG trinucleotide repeats. RESULTS: Patients in group 1 scored 2.9 points and patients in group 3 scored 4.2 points below their respective controls on the Mini-Mental State Examination. Patients in groups 1 and 3 were similarly impaired in verbal memory. Visual function was much more impaired in patients in group 3, and prefrontal functions were slightly worse in patients in group 1. Cognitive scores were correlated only with time of evolution for patients in group 2. Functional scores were not significantly different among the 3 groups, but 11 (85%) of the patients in group 3 were in stage I or II vs 10 (67%) of the patients in group 1. Total functional capacity correlated better with the Mini-Mental State Examination score for patients in group 3 and with motor deficits (akinesia) and prefrontal dysfunction for patients in group 1. The mean+/-SD CAG repeat length decreased from 59.9+/-12.6 for patients in group 1 to 46.2+/-3.5 for patients in group 2 and 41.7+/-2.6 for patients in group 3. Longer CAG repeats in the HD study population correlated with akinetic features but not with cognitive performance. CONCLUSIONS: Despite the much greater genetic defect, cognitive status is slightly better preserved in patients with juvenile-onset HD. Cognitive impairment in patients with juvenile- and late-onset HD differs in the severity of visual and prefrontal deficits. Functional disability in patients with late-onset HD depends more on global cognitive status, while in patients with juvenile-onset HD, it is conditioned more by motor deficits and prefrontal dysfunction.

[Angelman syndrome: physical characteristics and behavioural phenotype in 37 patients with confirmed genetic diagnosis].

INTRODUCTION: Angelman syndrome (AS) is characterised by mental retardation, ataxic gait, epilepsy, absence of language and a special series of physical traits behavioural phenotype. Its incidence is estimated as one in every 20,000 individuals. On the basis of discoveries made in molecular biology, patients can be classified as belonging to five types: deletion, paternal uniparental disomy (UPD), imprinting defects, mutation of the UBE3A ubiquitin protein ligase gene and unidentified mechanism (15% 20% of patients). Some studies report significant correlations between the phenotype and the genetic cause. PATIENTS AND METHODS: We reviewed, retrospectively, 37 patients suffering from AS with a positive genetic study and who had been controlled for at least two years in the Neurological Service at the Hospital Sant Joan de D u. Data was collected on physical characteristics, behavioural phenotype, type of communication, sleep disorders and the medication they needed, as well as epilepsy, start age, types of seizures, medication, schooling and social integration. RESULTS: 87% of cases were due to de novo deletion, 8% were caused by UPD, and 5% had their origins in imprinting defects. The average age of diagnosis was 6.5 years. The sleep disorders present in 48% of the patients required medication in 67% of cases, and 95% presented epilepsy. The most frequent seizures were myoclonic, tonic clonic and atonic. The electroencephalogram (EEG) was the characteristic found in the AS in 68%. The most effective treatment was afforded by valproate and clonazepam. CONCLUSIONS: As regards the phenotype, no differences were found according to the genetic alteration. The most effective treatment for the sleep disorders was melatonin. Epilepsy was an almost constant finding in our series, as was cognitive affectation. Lastly, it must be pointed out that educational and socio occupational integration is difficult for patients suffering from AS.

The relation between EEG and mental development following cardiac surgery performed under simple deep hypothermia in children.

In order to assess the accuracy of electroencephalography (EEG), in children who have undergone cardiac surgery under simple deep hypothermia, the relation between IQ or schoolwork achievement and the duration of circulatory arrest was investigated in 75 such children. Abnormal preoperative EEG's were found in 16 per cent of the children while abnormal postoperative EEG's were found in 17 per cent. The children were divided into 4 groups, according to pre- and postoperative EEG results. Schoolwork achievement scores ranged between 3.0 and 3.2, the difference among the groups being insignificant. Moreover, no significant shift in IQ was found among the groups. Finally, regarding the number of children who were able to go on to a higher level of education, including high school then college or university, again no significant differences were found among the 4 groups. In a comparison with the number of such children in neighboring Nagasaki prefecture able to continue on to a higher level of education, no significant differences were seen either. The findings and statistics of this investigation therefore indicate that pre- and postoperative EEG's are not always a reliable reference for assessing the prognosis of cerebral activity.

Hypernatremia in hospitalized patients.

OBJECTIVE: To determine the incidence, clinical characteristics, and outcome for general medical-surgical hospital patients with hypernatremia. DESIGN: A prospective cohort study. SETTING: A 942-bed urban university hospital. PATIENTS: All patients who developed a serum sodium concentration of 150 mmol/L or greater during a 3-month observation period. MEASUREMENTS: Daily fluid balance, mental status, and serum and urine electrolytes and osmolality. RESULTS: 103 patients were identified. Eighteen patients were hypernatremic on hospital admission, and 85 developed hypernatremia during hospitalization. Patients who developed hypernatremia during hospitalization were younger than patients who developed hypernatremia before hospital admission (mean age +/- SD, 58.9 +/- 19.2 years compared with 76.6 +/- 16.6 years; P < 0.01) but did not differ in age from the patients of the general hospitalized population. Eighty-nine percent of patients who developed hypernatremia during hospitalization had urine concentrating defects, primarily as the result of the use of diuretics or of solute diuresis, whereas only 50% of patients who were hypernatremic on admission could be shown to have concentrating defects (P < 0.01). Fifty-five percent of all hypernatremic patients had increased insensible water losses, and 35% had increased enteral water losses. Eighty-six percent of patients with hospital-acquired hypernatremia lacked free access to water, 74% had enteral water intake of less than 1 L/d, and 94% received less than 1 L of intravenous electrolyte-free water per day during the development of hypernatremia. No supplemental electrolyte-free water was prescribed during the first 24 hours of hypernatremia in 49% of patients. The duration of hypernatremia was shorter in patients who were hypernatremic on admission (median duration, 3 days) than in patients with hospital-acquired hypernatremia (median duration, 5 days; P < 0.05). Mortality was 41% for all patients, but hypernatremia was judged to have contributed to mortality in only 16% of patients. CONCLUSIONS: Although the development of hypernatremia before hospital admission occurs primarily in geriatric patients, hospital-acquired hypernatremia was more common in our cohort and had an age distribution similar to that of the general hospitalized population. Hospital-acquired hypernatremia was primarily iatrogenic, resulting from inadequate and inappropriate prescription of fluids to patients with predictably increased water losses and impaired thirst or restricted free water intake or both. Treatment of hypernatremia is often inadequate or delayed. Efforts to manage hypernatremia better and altogether avoid hospital-acquired hypernatremia should focus on both physician education and the development of hospital systems to prevent errors in fluid prescription.
