Epileptic fits or infantile masturbation?

Two infants, one girl, 5 months old, and one boy, 6 months old, presented with rhythmic and sustained motor activities of a stereotyped nature accompanied by moaning and grunting, facial flushing and altered awareness. The episodes occurred frequently and were initially believed to be epileptic. Normal electroencephalograms during the fits, lack of response to antiepileptic medication given to one child and careful reviewing of videotape recordings, enabled us eventually to diagnose the 'seizure-like' episodes as masturbatory activity.

Cord blood IgE. I. IgE screening in 2814 newborn children.

Screening of total IgE in 2814 cord blood samples was analysed by Phadebas IgE PRIST in 2 1-year birth cohorts (1983-1984 and 1985-1986) in Denmark (n = 1189 + 1625). 48.6% of the sera contained less IgE than the detection limit 0.1 kU/l. Cord blood IgE values greater than or equal to 0.5 kU/l were regarded as elevated. 13.2% of the sera contained at least 0.5 kU/l of IgE, with a significant preponderance in boys. Geometric mean cord blood IgE was 0.13 kU/l and 0.12 kU/l, respectively. Geometric mean cord blood IgE was significantly higher in boys. A significant seasonal variation with lowest IgE values in the autumn was found. No correlation between cord blood IgE and birth weight or gestational age was demonstrated. Only few newborns had cord blood IgA values greater than 0.014 g/l, calculated as geometric mean cord blood IgA + 2 SD among children with no detectable cord blood IgE, indicating infrequent contamination with maternal blood.

Cord blood IgE. II. Prediction of atopic disease. A follow-up at the age of 18 months.

Screening of total IgE in 2814 cord blood samples was analysed by Phadebas IgE PRIST in 2 1-year birth cohorts (1983-1984 and 1985-1986) in Denmark (n = 1189 + 1625). For follow-up we chose all infants with cord blood IgE greater than or equal to 0.5 kU/l and a randomly chosen group of the same size with cord blood IgE less than 0.5 kU/l. A total of 762 infants were clinically evaluated at 18 months of age. A diagnosis of definite atopy, probable atopy or no atopy, including both IgE and non-IgE mediated disease was established. Applying different cord blood IgE cut-off values (0.3, 0.5, 0.8, 1.1) we did not find an excess of atopic infants among those with elevated cord blood IgE irrespective of the chosen cut-off value. Atopic predisposition or family history of atopic disease was defined as at least one parent or older sibling with atopic disease. Significantly more infants with a family history developed atopy at 18 months. In the 2 series the positive predictive values of cord blood IgE greater than or equal to 0.5 were 43% and 46% and the sensitivities were 17% and 15%. The predictive values of having a family history were 48% and 44% and the sensitivities were 55% and 58%.

Cord blood IgE. III. Prediction of IgE high-response and allergy. A follow-up at the age of 18 months.

Screening of total IgE in 2814 cord blood samples was analysed by Phadebas IgE PRIST in 2 1-year birth cohorts (1983-1984 and 1985-1986) in Denmark (n = 1189 + 1625). For follow-up we chose all infants with cord blood IgE greater than or equal to 0.5 kU/l and a randomly chosen group of the same size with cord blood IgE less than 0.5 kU/l. A total group of 762 infants were clinically evaluated at 18 months of age, and in 688 of these we evaluated total and specific IgE. A diagnosis of definite atopy, probable atopy or no atopy was established. In the present study we defined allergic disease as atopic disease combined with elevated total IgE. We found a statistically significant correlation between cord blood IgE and IgE at 18 months of age. Significantly more infants with elevated cord blood IgE had developed allergic disease at 18 months. A cut-off value of 0.3 kU/l for cord blood IgE was superior to the originally suggested 0.5 kU/l. Significantly more infants with elevated cord blood IgE had developed specific IgE antibodies at 18 months. The most frequent specific IgE antibody was towards cow's milk. Specific IgE antibodies were very rarely found when total IgE was not elevated. A total IgE at the age of 18 months greater than 26 kU/l could be regarded as elevated. With regard to allergic disease the positive predictive values of cord blood IgE greater than or equal to 0.3 kU/l in the 2 series were 21% and the corresponding sensitivities 67% and 46%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Danish primary schoolteachers' knowledge about asthma: results of a questionnaire.

We present an anonymous questionnaire inquiry involving 334 primary schoolteachers in the Randers area with the purpose of elucidating teachers' knowledge about asthma. To a series of statements about asthma, the teachers answered yes, no or don't know. A limited knowledge of different aspects of asthma in children was found, although 57% had asthma children in their classes. Specially limited was knowledge about medical treatment. Five percent had received proper instruction about asthma and had a significantly better knowledge of medical treatment (p less than 0.001-0.05). Only 57% knew that wheezing after physical exertion is a strong indicator of asthma and only 33% knew that exertion in cold weather increases the risk of an attack. It is recommended that instruction in children's diseases, especially asthma, is introduced in teacher training colleges.

[Infection as the precipitating factor in Schönlein-Henoch purpura].

Shönlein-Henoch's purpura (SHP) is a form of generalized vasculitis. SHP is characterized by a haemorrhagic eruption, colicky abdominal pain, renal involvement with haematuria and proteinuria, arthralgia and cerebral symptoms in the form of headache and seizures. Retrospective investigations have revealed that infection with microorganisms may precipitate SHP. The authors were able to support this observation by means of a prospective investigation. 2/3 of the 26 children in the investigation had symptoms of infection one to two weeks prior to the onset of symptoms of SHP. Ten children had definite positive signs of prior infection. The course of the sedimentation rate and leukocyte counts also support the assumption of previous infection.

Neurologic manifestations of Schönlein-Henoch purpura.

The presence of a possible cerebral involvement in Schönlein-Henoch Purpura was investigated in a prospective study comprising 26 children. A hampering headache accompanied by behavioural changes was present in 8 patients (31%). No cases of seizures, aphasia, ataxia, pareses or cerebral haemorrhage were found. EEG-abnormalities like slow wave foci, sharp waves, and paroxysms were demonstrated in 12 patients (46%) during the acute phase of the disease. The EEG-changes were transient but persisted in 4 patients during a follow-up period lasting one year. A significant association was found between the presence of headache and an abnormal EEG-tracing.

[Spontaneous perforation of the biliary tract during the neonatal period].

Spontaneous perforation of the biliary passages is a rare condition during the first months of life. The course of the condition may be acute or more chronic. The symptoms are jaundice, clay-coloured stools, dark urine, distended abdomen, regurgitation and failure to thrive. The diagnosis can be established by scanning of the abdomen and 99mTc-HIDA-scintigraphy of the biliary passages. The perforation is usually found to be localized to the transition between the cystic duct and the common hepatic duct and is probably due to a localized development defect in the biliary passages. Operation is always required. The prognosis is good and the infants do well after operation.

[Intervertebral discitis in children].

Intervertebral discitis in children is a benign inflammatory condition with a varied clinical picture and quite characteristic radiographic findings. The etiology is still unknown and infectious and traumatic geneses have been discussed. A case in a girl aged three years is described and treatment with antibiotics and immobilisation are discussed.

Diagnostic value of a glass fibre-based histamine analysis for allergy testing in children.

The aim of this study was to compare the diagnostic value of common allergy tests with basophil histamine release in 124 children with symptoms of asthma. The patients were evaluated by case history, skin prick test, RAST-analysis, and basophil histamine release using a glass fibre-based histamine assay to 10 common inhalant allergens. The bronchial provocation test was used as a reference of "true" IgE-mediated asthma. To compare the various diagnostic parameters each absolute test value was classified into a scoring system. The concordance between the tests varied between 85-97%. In general, the best concordance was found between basophil histamine release and RAST. Sensitivity, specificity and predictive values were calculated on the basis of 104 bronchial provocation tests. It was found that histamine release was the best single analysis, followed by RAST and prick testing. The sensitivity of RAST and histamine release was very high (1.00) for pollen and house dust mites. Histamine release showed a predictive value between 0.91 and 1.00 for pollen and house dust mites, thus indicating the possibility of omitting the bronchial provocation test. In the dander group histamine release gave the best sensitivity (0.91), however at the expense of specificity (0.64), whereas RAST and skin prick test gave a specificity of 1.00. In the mould group histamine release also showed the best diagnostic value. The combination of skin testing with histamine release or RAST was of no additional diagnostic help. It is concluded that the glass fibre-based histamine analysis, which makes routine histamine release testing possible, is a reliable diagnostic test in children.

Hepatosplenic candidiasis in children with cancer. Three cases in leukemic children and a literature review.

Three children with acute leukemia presented with prolonged fever and neutropenia after cytostatic therapy, which was followed by abdominal pain, hepatomegaly, and hepatic dysfunction with raised serum alkaline phosphatase. Abdominal CT scan and ultrasound demonstrated multiple small lesions compatible with the hepatosplenic candidiasis syndrome. Liver biopsies showed microabscesses with a granulomatous appearance, but evidence of yeasts and pseudohyphae was present in 1 case only. Cultures were negative. Treatment with amphotericin B and 5-fluorocytosine was successful in two children. At autopsy, one child had signs of active infection. We reviewed the literature on 27 children with hepatosplenic candidiasis. Abdominal symptomatology and prolonged fever, despite antibiotic therapy, in a patient with previous or present neutropenia after cytotoxic exposure, should lead to a careful evaluation, including noninvasive imaging studies, open liver biopsy, and prompt aggressive antifungal treatment, the response to which requires close follow-up.

[Tuberous sclerosis].

Tuberous sclerosis (TS) is a congenital disease with hamarthromata, localized in particular to the central nervous system and skin. Other organs such as the heart, kidneys and eyes are, however, frequently involved. The disease is much more common than originally assumed. The most recent investigations show a prevalence of 1:9,704. TS is a dominant hereditary disease but with varying penetration. The frequency of mutation is probably less than previously assumed. The gene for TS is localized to the long arm of chromosome 9 (q34). Prenatal diagnosis is not yet possible. The symptoms and the course of condition depend upon the organ system involved, the age of the patient and of the varying penetration. All patients with TS must be examined with Wood's lamp, and be submitted to sonography of the kidneys, echocardiography, ophthalmic examination and computed tomography of the cerebrum. Treatment is purely symptomatic but surgical intervention may be considered. The present authors recommend that all patients with TS are submitted to the abovementioned examinations once annually with the exception of computed tomography of cerebrum which is undertaken if cerebral involvement is suspected.

[The relation of birth weight and gestational age in a group of infants in Jutland with special reference to diagnosing infants with intrauterine growth retardation].

The relationship between birthweight (BW) and gestational age (GA) in 14,276 Danish children with GA of 35 to 42 completed weeks was illustrated employing 10%, 50% and 90% percentile curves. The curves were sex-specific. The number of light for dates (LFD) children defined by means of the 10% percentile (BW below 10th percentile) was 1,351 compared to 848 children when using the curve currently employed. The latter curve was based upon foreign children and moreover was not sex-specific. It is concluded that sex-specific and updated curves representing the population studied are mandatory in the diagnosis of LFD-children.
