Abstract
We investigated prospectively the incidence of autistic disorder (AD) in the neonatal intensive care unit and the risk factors associated with autistic development. The study population included the 5,271 children at St. Mary's Hospital and the diagnosis of AD was performed using DSM-III-R criteria. A total of 36 prenatal, perinatal, and postnatal factors were evaluated in the patients with AD, 57 cerebral palsy (CP), and 214 controls. AD was identified in 18 of the 5,271 children and the incidence was 34 per 10,000 (0.34%). This value was more than twice the highest prevalence value previously reported in Japan. Children with AD had a significantly higher history of the meconium aspiration syndrome (p = .0010) than the controls. Autistic patients had different risk factors than CP.

Abstract
The objective of this study was to assess the prevalence of Helicobacter pylori seropositivity in institutionalized patients with severe neurologic impairment. Anti-H. pylori immunoglobulin G antibody in serum was measured in 196 institutionalized Japanese patients using enzyme linked immunosorbent assay, taking an antibody level >50 units/ml as evidence of H. pylori seropositivity. Patient age pattern and duration of institutionalization were examined for the relationships with H. pylori seropositivity. We also examined for seroconversion indicating new H. pylori infection in initially negative patients 1 year later. Positivity for H pylori infection among institutionalized patients was also compared with positivity among patients living at home. H. pylori seropositivity was present in 81.1% of subjects. Prevalence of H. pylori seropositivity increased with both age and duration of institutionalization. The serum level of anti-H. pylori immunoglobulin G antibody in patients over 20 years old was consistently high, approximately twice that of subjects less than 10 years of age. Of 38 patients initially negative for H. pylori infection, 18 (47.4%) had become positive at 1 year. H. pylori seropositivity was significantly more prevalent among institutionalized patients than among patients living at home (P < 0.0001). This study confirms that high H. pylori seropositivity rates are found among institutionalized patients with severe neurologic impairment. Our observations suggest person to person transmission, with fecal to oral, salivary secretion and respiratory droplet routes possibly being important pathways.

Abstract
To assess the efficacy of early intervention (EI) for very-low-birth-weight (VLBW) infants, we evaluated 62 2 year old children who were enrolled in an EI program and 48 control subjects aged 2 years. We determined the subjects' developmental quotients (DQ) and obtained information about the parents' evaluation of the children from a questionnaire sent to the parents. There was no significant difference in the DQ between the EI group and the control group. However, based on the responses to the questionnaire, subjects in the EI group showed slight, but statistically marginally significant, improvements in behavioral problems, especially a decrease in hyperkinesia, in adjusting to a circadian sleep cycle, and an improvement in language development, as compared with the control group (P < 0.1). Thus, EI for VLBW infants is considered useful to enhance some areas of development.

Abstract
BACKGROUND The postoperative intravesical instillation of doxorubicin (ADM) has a preventative effect on recurrence after a transurethral resection (TUR) of superficial bladder cancer. However, the significance of preoperative ADM instillation remains unclear. Although the oral administration of 5-fluorouracil (5-FU) has been observed to show some clinical response against bladder cancer, its preventative effect on the recurrence of superficial bladder cancer after TUR is unknown. METHODS Patients were randomized into 4 groups. All 4 groups received postoperative ADM instillation. In addition, patients in groups C and D received preoperative ADM instillation, whereas patients in groups B and D additionally received oral 5-FU postoperatively. The nonrecurrence rate and side effects were both compared among the 4 groups. RESULTS Of the 282 patients registered, 200 were evaluable, with a median follow-up period of 21.4 months. There were no significant differences in the characteristics of the patients among the 4 groups. Group C (pre- and postoperative ADM) showed a significantly longer disease-free interval than group A (postoperative ADM alone). However, there was no significant difference in the disease-free interval between groups A and B (postoperative ADM plus 5-FU), or between groups C and D (pre- and postoperative ADM plus 5-FU). Bladder irritation symptoms were the most frequently noted side effect encountered in all groups, but the severity was generally mild. CONCLUSIONS Preoperative ADM instillation was found to prevent recurrence to a greater extent than the usual postoperative instillation alone, whereas oral 5-FU was found to have no additional beneficial effect on the disease-free interval in patients with superficial bladder cancer.

Abstract
The objective of this study was to assess, in a developing country setting, the effect of dexamethasone therapy on bacterial meningitis outcomes. A prospective double blind placebo controlled trial was conducted in 89 children aged from 2 months to 12 years suffering from bacterial meningitis. Neurological, developmental, and hearing assessments were conducted at one, four, and 12 months after discharge. Forty eight patients received dexamethasone and 41 placebo. Initial antimicrobial drugs used were ampicillin and chloramphenicol. For all patients at the time of admission the mean duration of illness was 5.7 days; 47% had had seizures and 56% had impaired consciousness. Seventeen of 89 (19%) patients died. The mortality for the dexamethasone group was 25% as compared with 12% in the group receiving placebo. Presentation to the hospital after four days of symptoms and with impaired conscious state were independent predictors of death. Of the dexamethasone group survivors, 26.5% had neurological sequelae and 42.3% had hearing impairment, whereas in the placebo group it was 24% and 30% respectively. Altered state of consciousness was a predictor of neurological sequelae. The presence of neurological sequelae and high cerebrospinal fluid protein independently predicted hearing loss. No beneficial effect of dexamethasone was observed on morbidity or mortality of this group of patients with bacterial meningitis. Dexamethasone is therefore not useful in developing countries as adjunctive treatment in patients seriously ill with bacterial meningitis, who present late for treatment and have been partially treated.

Abstract
We prospectively evaluated the intellectual development of 33 children who were born to 33 diabetic Japanese mothers and compared them to 34 children born to non-diabetic mothers (controls) during the same period at Kurume University Hospital between 1987 and 1989. Birthweight, maternal age and the infant's age at the time of intelligence testing did not differ significantly between the offspring of diabetic mothers (ODMs) and controls. Tanaka-Binet intelligence scores were significantly lower in the ODMs at 3 years of age than in controls (98.4 +/- 17.4 versus 113.4 +/- 15.3) (p = 0.0005). No correlation was found between IQ and maternal haemoglobin A1c levels during pregnancy. Maternal age and infant IQ were inversely correlated in ODMs (p = 0.0298, r = -0.3984), but no such correlation was demonstrated in the controls. The results indicated that the ODMs may show a poorer intellectual development than those of non-diabetic mothers.

Abstract
In order to establish an early intervention (EI) system for very-low-birth-weight infants, we designed a randomized trial at multiple institutions in Japan. We also reviewed the concept and history of early intervention in USA. Eight medical institutions in different locations were selected for participation. Sixty-two EI group patients and 48 controls without neurological abnormalities (age 2 years) were selected for study. The developmental quotient (DQ) by the revised Kyoto-K method and 15 questionnaire items were monitored twice, at the age of 2 and after one year of EI (3 years). Improvements in behavioral problems, circadian rhythm, and speech were significantly greater in the EI group than in the control group. (P < 0.01). Data on all patients are being collected, and further evaluation and analysis of DQ are planned. The most effective EI method in each specific location and the financial support of its official institutions are required for the success of the EI program for very-low-birth-weight infants.

Abstract
We conducted a questionnaire study of immediate allergy to natural rubber gloves among 2,408 medical workers who had used rubber gloves at Kumamoto University Hospital and allied hospitals. The response rate was 64.5% (1,321 workers). Among them, 8.5% (7.0-10.0% at 95% confidence limit) replied that they had experienced immediate allergy to rubber gloves. There were significant correlations among the frequency of rubber glove use, a history of atopic dermatitis or contact dermatitis, and the presence of skin lesions due to allergic reactions to rubber gloves. In 27 workers, skin lesions were associated with general symptoms. Of 59 workers who experienced immediate allergy and were tested for latex-specific IgE, 4 persons were positive. We conclude that the frequency of contact allergy to natural rubber products is substantially prevalent among Japanese hospital personnel and that education and awareness of this allergy are important.

Abstract
Fetal bile acids (1 beta-hydroxylated, 6 alpha-hydroxylated and unsaturated bile acids), especially 1 beta, 3 alpha,7 alpha, 12 alpha-tetrahydroxy-5 beta-cholan-24-oic acid (CA-1 beta-ol), have been detected in urine and feces early in life. To investigate whether a fetal pathway of bile acid synthesis exists in infancy, we measured the concentrations of bile acids in the urine, meconium and feces from normal newborns and infants by means of gas chromatography-mass spectrometry. The mean ratio of total bile acids to creatinine in urine increased between birth and 7 days and then gradually decreased; however, the concentration of total bile acids in urine remained significantly higher than that in adult urine until 3 mo of age. The main urinary bile acid was CA-1 beta-ol, and substantial amounts of fetal bile acids were detected in urine until 3 mo of age. The ratio of cholic acid to chenodeoxycholic acid was abnormally low in meconium (mean, 0.44; range, 0.19 to 0.74), and hyocholic acid constituted 19.3% of total bile acids. The mean total bile acid content of feces decreased between birth and 7 days of age and thereafter increased. The mean percentage of fetal bile acids in feces decreased after birth, but substantial amounts were present in feces until 1 mo of age.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To construct standard growth curves for Japanese infants of very low birth weight (VLBW) with birth weights of 500-1499 g, we reviewed longitudinal data provided by 54 neonatal intensive care units in Japan. A total of 382 surviving singleton infants, appropriate for gestational age infants, and who were free of neurological sequelae at more than 2.5 years of age, were enrolled. Growth curves, including body weight, head circumference and body length were generated for four ranges of birth weight: 500-749 g, 750-999 g, 1000-1249 g, and 1250-1499 g. When compared with previously published growth data from western countries, Japanese infants of VLBW showed greater weight loss, regained birth weight more slowly, and exhibited smaller average gains in weight, head circumference, and body length. The growth curves reported in western countries may not be useful as reference standards of early postnatal growth in Japan. The new growth curves are a more accurate reflection of current in-hospital growth trends in Japan.

Abstract
We analyzed lactate, pyruvate, and citric acid cycle intermediates in cerebrospinal fluid by high-performance liquid chromatography in Rett syndrome patients (n = 27; mean age, 5.7 +/- 3.4 years) and age-matched female controls (n = 12; mean age, 7.0 +/- 3.3 years). The lactate, pyruvate, alpha-ketoglutarate, and malate were significantly elevated in Rett syndrome compared to the controls. The lactate/pyruvate ratio was not different. On the other hand, cerebrospinal fluid citrate, cis-aconitate, succinate, fumarate, and oxaloacetate were not significantly different in Rett syndrome patients than in the controls. We also evaluated the correlation between these acids and clinical symptoms and signs, including clinical stage, seizures medications (anticonvulsants or naltrexone), developmental quotient, self-abuse, and hyperventilation or apnea or both. The concentrations of all these acids did not differ significantly with clinical stage. Lactate elevation significantly correlated with apnea. Lactate and pyruvate elevation significantly correlated with hyperventilation or with both breathing abnormalities. Our observations in this sample of patients with Rett syndrome led us to speculate that patients with the Rett syndrome may have defective carbohydrate metabolism. Elevated mitochondrial reduced nicotinamide-adenine dinucleotide-linked substrates suggest that reduced nicotinamide-adenine dinucleotide-ubiquinone oxidoreductase may be deficient in the brain in Rett syndrome patients.

Abstract
Immunohistochemical staining with monoclonal antibodies detected ICAM-1 in about 69% of 55 primary melanoma lesions and in about 89% of 28 metastatic lesions. The average number of melanoma cells stained by anti-ICAM-1 monoclonal antibodies was approximately 65% in both primary and metastatic lesions. ICAM-1 expression in primary lesions was significantly associated with their thickness. Furthermore, ICAM-1 expression in primary lesions was associated with a reduction in the disease-free interval and with survival. At variance with the information in the literature, the association with clinical parameters of the disease did not reach the level of statistical significance. This discrepancy is likely to reflect the inclusion in the present study of a small number of primary lesions with a thickness < 1.5 mm. At variance with recently published data, the level of serum ICAM-1 in 75 patients with malignant melanoma was found to be nonsignificantly different from that in 47 age- and sex-matched controls. The level of serum ICAM-1 was significantly increased only in patients with stage III melanoma with lesions and in those with stage IV melanoma. Two novel and clinically relevant findings of the present investigation are (a) the significantly higher serum ICAM-1 level in patients with liver metastases than in those with metastases in other anatomic sites and (b) the progressive increase of ICAM-1 level in serial blood samples from patients with disease progression. The latter findings suggest that monitoring of serum ICAM-1 level may represent a valuable noninvasive indicator system to detect liver metastases and to monitor the clinical course of the disease in patients with malignant melanoma.

Abstract
In a recent study we detected marked differences in the antigenic profile of acral lentiginous melanoma (ALM) and nodular melanoma lesions. Furthermore, we showed that the human high molecular weight melanoma-associated antigen (HMW-MAA) is expressed with a significantly higher frequency in metastatic than in primary ALM lesions. Because of the potential role of HMW-MAA in the metastatic process of melanoma cells, in the present investigation we tested whether HMW-MAA represents a useful prognostic marker in ALM. Primary ALM lesions removed from 32 patients were stained with anti-HMW-MAA monoclonal antibody (mAb) in an immunoperoxidase reaction. The results were correlated with the expression of other markers defined by mAb, with clinical parameters of the disease, and with histopathological characteristics of the lesions. Only 9 of the 32 primary ALM lesions tested were stained by anti-HMW-MAA mAb. Expression of HMW-MAA was the only variable associated with patients' survival and disease-free survival. Both were significantly shorter in patients with HMW-MAA expression in their primary lesions. These results suggest that HMW-MAA may represent a novel prognostic marker in ALM, since phenotyping of primary ALM lesions with anti-HMW-MAA mAb may provide information about the prognosis of the disease which cannot be obtained with known prognostic parameters.

Abstract
To construct standard growth curves for Japanese infants of very low birthweight, longitudinal data provided by 47 neonatal centers in Japan were reviewed. Data were collected on the growth of infants admitted to those units during 1986 and 1987 and who survived beyond 3 years of age. A total of 379 singleton infants, who were free of neurological sequelae and appropriate for gestational age, were enrolled. Those whose birthweights were more than 600 g and less than 1,500 g were grouped into nine weight categories separated by increments of 100 g. Data on the increase in weight and head circumference were compiled and analyzed until more than half the infants in each weight category had been discharged from each site. Growth curves of bodyweight and head circumference in the nine groups were constructed using polynomial regression analysis to define the curve of best fit. With increasing prematurity, significant trends of greater weight loss (P < 0.05), longer time to reach the lowest weight (P < 0.01) and a longer time to regain birthweight (P < 0.01) were observed. In addition, there was a significantly higher incidence of chronic lung disease in such groups (P < 0.0001). Growth curves were characterized by the average clinical profiles in each of the nine groups. We believe that these data will be useful in evaluating the growth of very low birthweight infants being cared for in modern neonatal intensive care units in Japan.

Abstract
A nationwide survey of transient hyperammonemia in newborns was carried out in Japan. A total of 18 patients, consisting of 12 male and 6 female infants, were reported from 11 facilities. These neonates exhibited hyperammonemia with plasma ammonia levels in the range from 124 to 6256 micrograms/dl. Four newborn infants of the 18 died in the neonatal period, and an additional one died in the early infancy. Among the 13 infants who were alive at the time of this survey, 6 had neurological sequelae, including mental retardation, spastic quadriplegia and epilepsy. The multivariate analysis revealed that the Apgar score at 1 minute, peak plasma ammonia concentration, birth weight and sex were significant factors affecting the prognosis of life.

Abstract
The effect of AS-4370 on gastric emptying was investigated in healthy adults using 99mTc-DTPA. Single doses of AS-4370 2.5, 5 or 10 mg or placebo were administered to 12 subjects in a controlled, double-blind, cross-over study. Tests were performed twice weekly in each subject. Thirty min after administration of test drug or placebo, each subject swallowed a bun and orange juice containing 200 microCi nuclide. The radioactivity of the gastric content was measured for 40 min and the activity of the residue was expressed as a percentage of count at the initiation of measurements. The percentage radioactivity, AUC and gastric emptying time fitted by a power exponential curve, were analyzed. No significant difference was observed between the three dose levels of AS-4370 and placebo in half emptying time. However, decreases in the percentage of radioactivity with time were noted; 5 mg at 10 to 16 min and 10 mg at 8 to 24 min after the start of recording. Lower AUCs after 5 mg and 10 mg compared to placebo were also found. The half emptying time was also shorter after 5 mg and 10 mg than placebo. There was no difference in these parameters between 2.5 mg and placebo. The results indicate that AS-4370 5 and 10 mg but not 2.5 mg accelerates gastric emptying in healthy adults.

Abstract
The reactivity in an avidin-biotin complex immunoperoxidase reaction with a large panel of anti-human melanoma associated antigen (MAA) and anti-HLA monoclonal antibodies of 24 primary and 11 metastatic acral lentiginous melanoma (ALM) lesions was compared to that of 12 primary and 12 metastatic nodular melanoma (NM) lesions. The expression of the membrane bound vitronectin receptor, Mr 110,000 MAA, Mr 97,000 MAA, and intercellular adhesion molecule-1 was significantly lower in both primary and metastatic ALM lesions than in their NM counterparts. Furthermore, primary ALM lesions displayed a significantly lower expression than primary NM lesions of the membrane bound high molecular weight melanoma associated antigen (HMW-MAA), Mr 110,000 MAA, Mr 100,000 MAA, 9-O-acetyl-GD3, GD2-GD3, and GD2, of the cytoplasmic monoclonal antibody 465.12 defined MAA and of transferrin receptor and of HLA-DQ and DP antigens; ALM metastases expressed a significantly lower level of carcinoembryonic antigen-MAA than NM metastases. These antigenic differences do not reflect an antigenic paucity of ALM cells, since ALM lesions express a higher level of T4-tyrosinase than NM lesions and a level of HLA Class I antigens similar to that of NM lesions. In view of the use of HMW-MAA, Mr 97,000 MAA, and GD3 in immunoscintigraphy and/or in immunotherapy, it is noteworthy that the three antigens are expressed in a similar high percentage of ALM metastases and of primary and metastatic NM lesions, while the HMW-MAA is expressed in a markedly lower percentage of primary ALM lesions than Mr 97,000 MAA and GD3. However, the degree of heterogeneity of HMW-MAA within a positive primary ALM lesion, as measured by the percentage of stained melanoma cells, is lower than that of Mr 97,000 MAA and GD3. The expression of the antigens investigated in ALM and NM lesions was not correlated with the presence of lymphocyte infiltrates, melanin content of melanoma cells, and epithelioid and spindle type of melanoma cells in the lesions. On the other hand, the survival of patients with ALM was inversely correlated with the expression of intercellular adhesion molecule 1 or HMW-MAA in their primary lesions. A potential role of HMW-MAA in the course of the disease is suggested by its significantly higher expression in metastatic than in primary ALM lesions.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The effect of AS-4370 given in single doses of 2.5, 5 and 10 mg on gastric emptying was investigated using 99mTc-DTPA in healthy volunteers in the placebocontrolled double-blind crossover design. There was no difference in percent activity throughout the period of measurement between AS-4370 2.5 mg and placebo. The percent activity decreased after administration of 5 and 10 mg of AS-4370 in comparison with placebo: the decrease was found during the period from 10 to 18 minutes after start of recording at 5 mg and from 8 to 18 minutes after start of recording at 10 mg. These results demonstrated that AS-4370 at these dose levels apparently accelerated gastric emptying. The analysis of the half emptying time by the crossover method showed that only the time effect was found at 2.5 mg, whereas the half emptying time was obviously shortened at 5 and 10 mg. There was no difference between 5 mg and 10 mg. There was no finding that might warrant a caution in terms of safety. In conclusion, AS-4370 did not affect gastric emptying at 2.5 mg but apparently accelerated gastric emptying at 5 and 10 mg in healthy volunteers.

Abstract
Two epileptic patients treated with anticonvulsants of valproic acid, phenobarbital, nitrazepam, and diphenylhydantoin developed anorexia, convulsions, and unconsciousness. The liver biopsy samples showed degenerated hepatocytes containing enlarged mitochondria with a distorted matrix. The matrix granules in the mitochondria were enlarged in size as compared with those of chronic hepatitis (Po = 0.0009). X-ray microanalysis has revealed the presence of calcium in large mitochondrial matrix granules. Both patients were thought to have valproic acid intoxication because they recovered quickly after the withdrawal of valproic acid.

Abstract
The glomerular basement membranes (GBM) were measured in 264 patients with recurrent and persistent hematuria (152 males, 112 females), 47 patients with minimal change nephrotic syndrome (26 males, 21 females), and 91 patients with focal segmental glomerular sclerosis and nephrotic syndrome (55 males, 36 females). The average number of glomeruli measured was 2.5 per case. Analysis of the data showed GBM thickness to be significantly greater in males (n = 233) than in females (n = 169) (Student's t-test, P less than 0.01). There was no difference in GBM thickness between the two groups of nephrotics; the data were subsequently combined and the group referred to as idiopathic nephrotic syndrome. There was also no difference in GBM thickness among the immunofluorescence-defined subcategories of recurrent hematuria, and these groups were combined. GBM thickness was significantly greater in the idiopathic nephrotic syndrome than in recurrent hematuria (Kruskal-Wallis H test, Po = less than 0.001). Analysis of the data showed, in both conditions, a gradual increase with age throughout the span of the study (1-69 years). Regression analysis of GBM thickness and age in recurrent hematuria showed Ro = 0.43 and Po = less than 0.001, in idiopathic nephrotic syndrome Ro = 0.61 and Po = less than 0.001. The differences between nephrotic syndrome and recurrent hematuria may be based on the inclusion in the recurrent hematuria group of patients with genetically thin GBM; they may also be based on the inclusion in the idiopathic nephrotic syndrome group of patients with subendothelial thickening, a relatively frequent occurrence.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Propionibacterium acnes may have a role in Kawasaki disease. Filtrates from cultures of P acnes isolated from cervical lymph node biopsy specimens and blood samples from patients with Kawasaki disease were studied and compared with samples from control subjects. After inoculation of human embryo liver cells with filtrates from the patients a cytopathogenic effect and vacuolation were seen. A specific cytopathogenic substance was found in only the filtrates of cultures from patients with Kawasaki disease; it was a protein of about isoelectric point 7.0 with a molecular weight of about 100,000 daltons. The amount of IgG antibody to this cytopathogenic protein was measured by enzyme linked immunosorbent assay (ELISA) in serum samples taken from 63 patients in the acute phase of Kawasaki disease (mean 5.2 (SD 1.1) days after onset of illness), 45 in the subacute phase (mean 23.6 (3.3) days), and 51 in the convalescent phase (mean 18.5 (4.1) months) and from 102 control subjects matched for age. Titres of IgG antibody were significantly raised in patients with Kawasaki disease, particularly in the acute and subacute phases of the illness, compared with in the control subjects. Titres of IgG antibodies to cytopathogenic protein were found to be low in normal children below the age of 4 years but they increased with age thereafter. This may explain why outbreaks of Kawasaki disease, which is most common in children aged under 4, occur every three years.

Abstract
As congenital malformations may be caused by perturbations of glycolytic flux on early embryogenesis [16], effects of hypoglycaemia were investigated by using rat embryo organ culture. Nine and one-half day old rat embryos were grown in vitro for 48 h (day 9 1/2 to 11 1/2) in the presence of hypoglycaemic serum for different hours during the culture period. Hypoglycaemic serum was obtained from rats given insulin intraperitoneally. On exposure to hypoglycaemic serum during the first 24 h of culture (day 9 1/2 to 10 1/2), embryos showed marked growth retardation and had increased frequencies of neural lesions (42.7% versus 0%, p less than 0.01), in contrast to hypoglycaemic exposure during the second 24 h of culture (day 10 1/2 to 11 1/2), where only minor growth retardation and low frequencies of neural lesions (2.4% versus 0%, NS) were seen. Even exposure to hypoglycaemic serum for a relatively short period (8 h) during the first 24 h of culture resulted in neural lesions at the frequency of 9.3-13.3%. The embryos exposed to hypoglycaemia demonstrated decreased glucose uptake and lactic acid formation, indicating decreased energy production via glycolysis that constitutes the principal energy pathway at this stage of embryonic development. These results suggest that hypoglycaemia during critical periods of embryogenesis has adverse effects on the development of the embryo and these effects might be mediated through metabolic interruption of embryogenesis.

Abstract
Forty-seven patients (39 boys and 8 girls) with infantile autism whose clinical symptoms had matched the diagnostic criteria of DSM III were studied cytogenetically for the occurrence of fragile X [fra(X)] syndrome. The existence of fra(X) chromosome in these patients was screened first by culturing peripheral blood lymphocytes in a medium in which folic acid was absent; the fra(X) chromosome then was confirmed by reculturing in another medium to which 5-fluoro-2'-deoxyuridine was added for the last 24 hours of culture. Fra(X) chromosome was found in 2 of 39 male patients, but in none of the female patients; the 2 patients are siblings. Thus, fra(X) syndrome occurs in 2.6% (1/38) in this study population of male autistic children. The frequencies of fra(X) expression in the older brother with mild mental retardation, in the more severely retarded younger brother, and in their mother were 3-5%, 17-20%, and 9-3%, respectively. Of the two methods used in the present study, the method employing 5-fluoro-2'-deoxyuridine tended to be more sensitive to fra(X) chromosome detection, especially for a suspected carrier.

Abstract
The purpose of this study was to determine the prevalence of persistent blood pressure elevation in school children. Mass screening of blood pressure was performed simultaneously with a cardiovascular health check in school children. Forty four hundred and eighty school children were selected as subjects for this study, consisting of 2289 first grade primary school students aged six and seven (group A), and 2191 second grade junior high school students aged thirteen and fourteen (group B). Of the 4480 students, 4031 were examined at the initial blood pressure screening. Three hundred and sixty students whose systolic and/or diastolic pressures were above the 95th percentile were recalled for a second examination. Three hundred and thirty one students were studied at the 2nd examination, and 69 students were listed for a third survey. 1.7% of the original subjects were examined at the final survey. At the first screening, mean blood pressures were 101.5 +/- 8.5/61.2 +/- 6.6 mmHg (mean +/- SD) for males and 100.3 +/- 8.3/60.9 +/- 6.5 for females in group A. In group B, blood pressures were 120.2 +/- 11.3/66.6 +/- 7.4 mmHg for males and 117.4 +/- 11.2/66.9 +/- 7.8 mmHg for females. This screening system, if incorporated into the school health program, is an effective and efficient method of screening for persistent blood pressure elevation in school children in Japan.

Abstract
In Japan, diabetic patients are known to be able to sit on the floor for a prolonged time because of mildness or absence of ischemic paresthesia. In order to investigate this resistance to ischemia quantitatively, the mixed nerve function of the median nerve was studied during 30 min of ischemia using surface electrodes in 60 diabetic patients and 15 normal subjects. In studies of 33 unequivocal diabetics, potential amplitudes decreased during ischemia more slowly than in the controls, and at 15 min of ischemia, potential amplitudes were greater in all 33 diabetics than in the 15 normal subjects. The relationship between the resistance to ischemia and various aspects of diabetes was studied further in the 60 diabetics including the 33 aforementioned patients. Resistance to ischemia was found in almost all diabetics and no significant correlation was shown with values for fasting blood glucose and HbA1c, other diabetic complications or duration of diabetes. However, values for potential amplitudes declined to the normal range in seven of 18 patients after strict glucose control. These results suggest that resistance to ischemia is the earliest manifestation of peripheral nerve dysfunction and is different from classical diabetic neuropathy. Furthermore, the method employed in this study is simple, noninvasive and clinically very useful.

Abstract
The pretreatment characteristics of 158 children with previously untreated acute lymphoblastic leukemia diagnosed April 1972 to June 1978 were analyzed for their ability to predict prognosis. The children were treated according to therapeutic protocols 721, 745 and 765, by members of the Japanese Children's Cancer and Leukemia Study Group. Multivariate analysis was performed to determined the relationship between the characteristics and duration of survival of the patients. The following characteristics were analyzed: initial white blood cell (WBC) count, age at diagnosis, initial hemoglobin level, initial platelet count, sex, organomegaly, and treatment regimen that was provided. By using multivariate techniques, factors were found which the independently and significantly predict the length of survival. These factors were initial WBC count (r0 = 0.2908), age at diagnosis (r0 = 0.2982), and treatment regimen (r0 = 0.2488). Using the major prognostic factors of age at diagnosis and initial WBC count, a formula to predict the survival time was established. According to the initial WBC count and age at diagnosis, we classified all cases of childhood ALL as standard risk and high risk.

Favorable prognosis was exhibited only by those patients with initial WBC counts of less than 50,000/mm3, with age at onset between 2 and 6 years, without splenomegaly, and with hemoglobin levels between 5 and 10 g/dl. The most significant contributions among the various individual prognostic factors were initial WBC count (p less than 0.001) and the age at diagnosis (p less than 0.01).

Abstract
One hundred and twenty-four cases of pustulosis palmaris et plantaris (PPP) were studied by questionnaire survey to evaluate the effectiveness of tonsillectomy as treatment. We found that tonsillectomy as a method of treatment for PPP showed a significantly high rate of cure, against which other methods of treatment, e.g. corticosteroid therapy, PUVA therapy and so on, were compared. The examination, by means of Kaplan-Meier's method, showed a 59.2% cure rate for patients one year after tonsillectomy and 71.8% 2 years after the operation. When patients are older than 60 years, the prognosis is good, regardless of the method of treatment.

Abstract
In order to evaluate the clinical efficacy of glycosaminoglycan polysulfate (GAGPS) in osteoarthrosis of the knee, a double blind comparative study was carried out at 26 orthopaedic clinics throughout Japan. A total of 120 patients was divided into two groups; one group was treated with 1 mg GAGPS (control group) and the other with 50 mg GAGPS (drug group). Five or more injections (average: 9.3) were given at about weekly intervals (average: 8.2 days). The score derived from the knee scoring scale improved significantly in both groups, either after the 5th and the 10th injections. The score that had improved after the 10th injection in drug group was statistically superior compared to the control (p less than 0.05), however, the difference in the two groups after the 5th injection did not reach a level of any statistical significance. Doctors' assessment of the usefulness of the drug based on the balance of effects and side effects was obtained in 71.2% and 41.1% in drug group and control group, respectively. The difference was statistically significant (p less than 0.01). In conclusion, the authors confirmed that the intraarticular injections of 50 mg GAGPS were useful for osteoarthrosis of the knee although the clinical symptoms were improved only gradually following the injections.

Abstract
We carried out a controlled study on the voluntary control of the frontalis muscle by biofeedback procedures employing 20 normal subjects. Subjects were randomly divided into two groups of 10: (1) the biofeedback group and (2) the control group. Each of the two groups received five training sessions of about 40 minutes' duration each on different days. The results obtained are as follows: (1) In the biofeedback group, mean EMG levels decreased progressively and markedly from 2. 16 muVp-p min the first session to 1.54 muVp-p min in the last session. On the contrary, the control group did not show constant decreases in EMG levels over sessions. (2) The changes in the heart rate did not correlate with the changes in EMG activity. (3) The changes in the respiratory rate correlated with the changes in EMG activity.
