    Notes: Abstract Biliary lipid composition, standard liver function tests, serum lipids and faecal fat excretion were studied in 15 children with chronic intrahepatic cholestasis (severe intrahepatic cholestasis, n=6; paucity of intralobular bile ducts, n=4; benign recurrent cholestasis, n=5) and compared to 15 children without gastrointestinal diseases. Severe and benign intrahepatic cholestasis were associated with normal or moderately elevated serum lipids. Biliary lipid concentrations were extremely reduced, bile acid concentrations were below the critical micellar concentration. This may account for the high incidence of gallstone formation in these patients. Remission periods in patients with benign recurrent cholestasis were not followed by complete normalisation of biliary lipid concentrations, indicating a primary defect in hepatic excretory function. Children with paucity of intralobular bile ducts showed markedly increased serum lipids, but only a two-fold reduction in biliary lipid concentrations. Cholic acid was the predominant bile acid in bile of all cholestatic children even during remission. Neither increased levels of monohydroxy bile acids nor unusual bile acids could be identified in notable amounts.

    Notes: Abstract The effects of phenobarbital (5.4–7.5 mg/kg body weight) for 14 days were studied in four children with severe intrahepatic cholestasis (group I) and in four with a syndromatic type of paucity of intralobular bile ducts (group II). Phenobarbital administration resulted in a moderate improvement of pruritus in all patients. There was a significant decrease of bilirubin in serum (group I: from 4.8 to 2.7 mg/dl; group II: from 6.1 to 2.1 mg/dl); total bile acids (group I: from 416 to 337 μmol/l; group II: from 156 to 123 μmol/l) and cholesterol (group I: from 248 to 207 mg/dl; group II: from 351 to 292 mg/dl). Alkaline phosphatase activity increased from 929 to 1126 U/l in group I and from 1751 to 2360 U/l in group II. SGOT and SGPT activities remained unchanged in both groups. In group I total biliary lipid concentration and bile acid output increased from 0.09 to 0.17 g/dl and from 3.9 to 7.2 μmol/kg per 30 min, respectively. Molar percentages of cholesterol, phospholipids and bile acids in bile remained unchanged. In group II total lipid concentrations and bile acid output increased from 1.62 to 2.0 g/dl and from 27.8 to 39.1 μmol/kg per 30 min, respectively. The molar percentage of cholesterol decreased from 5.6 to 3.5 mol%. The present results indicate that short term administration of phenobarbital has only minimal effects on biliary lipid metabolism in children with chronic intrahepatic cholestasis.

    Efficient adiabatic population transfer by two-photon excitation assisted by a laser-induced Stark shift (2000)

    Notes: We demonstrate and analyze a novel scheme for complete transfer of atomic or molecular population between two bound states, by means of Stark-chirped rapid adiabatic passage (SCRAP). In this two-laser technique a delayed-pulse laser-induced Stark shift sweeps the transition frequency between two coupled states twice through resonance with the frequency of the population-transferring coupling laser. The delay of the Stark-shifting pulse with respect to the pulse of the coupling-laser Rabi frequency guarantees adiabatic passage of population at one of the two resonances while the evolution is diabatic at the other. The SCRAP method can give a population-transfer efficiency approaching unity. We discuss the general requirements on the intensity and timing of the pulses that produce the Rabi frequency and, independently, the Stark shift. We particularly stress extension to a double-SCRAP technique, a coherent variant of stimulated emission pumping in the limit of strong saturation. We demonstrate the success of the SCRAP method with experiments in metastable helium, where a two-photon transition provides the Rabi frequency. © 2000 American Institute of Physics.

    Notes: Precipitins against avian antigens in sera from patients with extrinsic allergic alveolitis, asymptomatic pigeon and chicken breeders and from control individuals were tested with different antigen extracts in six laboratories by a variety of different methods. Eighty percent of the results coincided in identifying the positive sera from patients and 90% in identifying the controls. It seems possible therefore to exchange results among experienced laboratories with fair confidence.

    Notes: Allergic diseases are more prevalent in affluent countries, which has been attributed to life-style factors. Life-style habits may also differ between socioeconomic (SES) classes. The objective of this paper therefore was to evaluate if SES had an impact on the development of atopic disorders.〈section xml:id="abs1-2"〉〈title type="main"〉MethodsA total of 1314 German children were followed-up in an observational birth cohort study to 6 years of age. Parents filled in questionnaires, and had multi-allergen screening tests for sensitization. Indoor allergen concentrations were determined by ELISA. Children were examined regularly up to 6 years, specific serum IgE values were determined by CAP-Rast-Feia.〈section xml:id="abs1-3"〉〈title type="main"〉ResultsThe risk of aeroallergen sensitization (odds ratio 1.76; 95% CI 1.30–2.37), and the lifetime prevalence of hay fever (2.36; 1.76–3.17), and asthma (1.74; 1.08–2.80), but not of atopic dermatitis (AD: 0.90; 0.54–1.51) was elevated in parents of high compared to low SES. With high SES the risk of smoking in pregnancy (0.35; 0.23–0.51), in the home (0.31; 0.21–0.46), pet ownership (0.37; 0.26–0.55), high mite (0.42; 0.25–0.74), and high cat (0.38; 0.18–0.82) allergen concentration in house dust was reduced, but elevated for breastfeeding over more than 6 months (4.67; 2.9–7.48). In children, even after controlling for other risk factors, only the risk of AD from 3 to 6 years (2.42; 1.42–4.14) was elevated in families with high SES, but not of AD in infancy or of any other atopic disorder.〈section xml:id="abs1-4"〉〈title type="main"〉ConclusionsWhile parents of high SES have a higher prevalence of inhalative allergies, their favourable life-style prevents the development of atopic disorders in their children, except for AD beyond infancy.

    Notes: Background The results of numerous studies on the influence of breastfeeding in the prevention of atopic disorders are often contradictory. One of the most important problems is confounding by other lifestyle factors.Objective The aim of the present study was to analyse the effect of any breastfeeding duration on the prevalence of atopic eczema in the first seven years of life taking into account other risk factors.Methods In an observational birth cohort study 1314 infants born in 1990 were followed-up for seven years. At 3, 6, 12, 18, 24 months and every year thereafter, parents were interviewed and filled in questionnaires, children were examined and blood was taken for in vitro allergy tests. Generalized Estimation Equations (GEE)-models were used to model risk factors for the prevalence of atopic eczema and for confounder adjustmentResults Breastfeeding was carried out for longer if at least one parent had eczema, the mother was older, did not smoke in pregnancy, and the family had a high social status. The prevalence of atopic eczema in the first seven years increased with each year of age (OR 1.05; 95% CI 1.01–1.09 for each year), with each additional month of breastfeeding (1.03; 1.00–1.06 for each additional month), with a history of parental atopic eczema (2.06; 1.38–3.08), and if other atopic signs and symptoms appeared, especially specific sensitization (1.53; 1.25–1.88), and asthma (1.41; 1.07–1.85). Although breastfeeding should be recommended for all infants, it does not prevent eczema in children with a genetic risk.Conclusion Parental eczema is the major risk factor for eczema. But in this study, each month of breastfeeding also increased the risk

    Topics: Medicine
    Notes: Objective:  A population study was performed to identify the prevalence of all kinds of adverse reactions to food.Methods:  In a representative cross-sectional survey performed in 1999 and 2000 in Berlin, 13 300 inhabitants of all ages were addressed by questionnaire. This questionnaire was answered by 4093 persons. All respondents mentioning any sign of food intolerance or the existence of allergic diseases (n = 2298) were followed up by telephone and, in case food intolerance could not be ruled out by patient history, were invited to attend to the clinic for personal investigation including double-blind, placebo-controlled food challenge tests (DBPCFC).Results:  The self-reported lifetime prevalence of any adverse reaction to food in the Berlin population (mean age 41 years) was 34.9%. Eight hundred and fourteen individuals were personally investigated according to the guidelines. The point prevalence of adverse reactions to food confirmed by DBPCFC tests in the Berlin population as a mean of all age groups was 3.6% (95% confidence interval [3.0–4.2%]) and 3.7% in the adult population (18–79 years, 95% confidence interval [3.1–4.4.%]). Two and a half percent were IgE-mediated and 1.1% non-IgE-mediated, females were more frequently affected (60.6%). Based on a statistical comparison with available data of adults from the nationwide German Health Survey from 1998, adverse reactions to food in the adult population of Germany (age 18–79) were calculated with 2.6% [2.1–3.2%]).Conclusions:  The study gives for the first time information about the point prevalence of both immunological and nonimmunological adverse reactions to food and underlines the relevance of this issue in public health. The data also show that an individualized stepwise approach including provocation tests is mandatory to confirm the diagnosis.

    Description / Table of Contents: Zusammenfassung Der duoenogastrische Reflux wurde quantitativ bei den klassischen Magenresektionsverfahren (Billroth II — mit und ohne Enteroanastomose, Billroth I), sowie bei Magengesunden bestimmt. Insgesamt wurden 43 Magenresezierte und 6 Magengesunde untersucht. Die B II-Resezierten ohne Braunsche Enteroanastomose (n = 10) wiesen einen Reflux von 50,4 ± 4,1 % (SEM) der während der Untersuchung sezernierten Gallenmenge auf. Bei den B II-Resezierten mit Braunscher Enteroanastomose (n = 15) betrug der Reflux 21,5 ± 3,7 % (SEM), bei den B I-Resezierten (n =17) 23,1 ± 3,5 (SEM). Die magengesunden Kontrollpersonen (n = 6) wiesen einen Reflux von 0,5 ± 0,4% (SEM) auf.
    Notes: Summary The duodenogastric reflux was measured quantitatively in patients with classic gastric resections (Billroth I, Billroth II with and without enteroanastomosis) as well as in patients without gastric operations. A total of 43 patients with gastric resection and 6 without gastric operation were studied. Patients operated according to B II without Braun's enteroanastomosis (n = 10) had a bile reflux of 50.4 ± 4.1 % (SEM) during the study. Patients having been operated according to B II- with Braun's-enteroanastomosis (n = 15) and those having undergone B I-operation (n = 17) had a duodenogastric reflux of 21.5 ± 3.7 % (SEM) and 23.1 ± 3.5 % (SEM), respectively. In 6 control subjects without gastric operation bile reflux into the stomach averaged 0.5 ± 0.4 % (SEM).
