Hyper-IgE syndrome is basically characterized by recurrent infections, chronic eczematous lesions, specific IgE antibodies against Staphylococcus aureus and markedly high serum IgE values. We present the case of an 11-year-boy with no relevant personal or family history, who came to our Department with highly pruriginous papulovesicular skin lesions of 3 years' duration. He presented marked obesity (+4 SD) and micropapulovesicular lesions in the trunk and extension areas of the limbs. The rest of the physical exploration was normal. Complementary studies revealed peripheral eosinophilia, increase in globular sedimentation rate and IgE values of 20,000 IU/ml, a nonspecific reaction to skin tests, and a skin biopsy compatible with atopic dermatitis. Three months later, he presented eczematous lesions in the trunk and limbs, perforation of the nasal wall due to staphylococcal abscess (diagnosed by biopsy), bilateral maxillary sinusitis and IgE values of 59,238 IU/ml. The differential diagnoses are discussed, as well as new diagnostic-therapeutic possibilities.

Macrophage migration inhibitory factor (MIF) was the first T-cell-derived soluble lymphokine to be identified. It was originally found to inhibit the migration of macrophages and activate them at inflammatory loci. During the past few years, however, previously unrecognized properties of MIF have been discovered. It also functions, for example, as a pituitary hormone, glucocorticoid-induced immunomodulator and isomerase. We cloned rat MIF cDNA and reported that the nucleotide sequence of the cDNA predicts a protein consisting of 114 amino acids. Northern blot analysis indicated that the MIF mRNA was expressed in a wide variety of organs, including the brain, kidney, and liver. Following this, we demonstrated definitively that MIF was expressed in a variety of cells, suggesting its involvement in various biological events such as wound healing, atopic dermatitis, and, possibly, diabetes/obesity. Furthermore, we elucidated its physicochemical properties, including the tertiary structures of both human and rat MIF. These tertiary structures showed that this protein forms a homotrimer with each monomer consisting of two beta/alpha/beta motifs, thus resembling 5-carboxymethyl-2-hydroxymuconate isomerase and d-dopachrome tautomerase. From the available data on MIF, including ours, it is considered that the protein is associated not only with immune responses but also with cell growth and differentiation during wound repair and carcinogenesis. Thus, MIF could become a major target protein in a variety of pathophysiological states and anti-MIF antibodies and antagonists could be applied therapeutically in the clinical situation for treatment of various diseases. Bearing this in mind, this review discusses the role of MIF, considering its gene and protein structures as well as its pathophysiological functions in various organs and disease states, finally considering perspectives for the future.

Acanthosis nigricans (AN) occurs associated with many different systemic diseases, such as endocrine disorders and internal malignant neoplasms. To our knowledge, the association of AN with severe atopic dermatitis (AD) or Down syndrome has not been described before. This 82-month retrospective study included 1038 patients: AN was present in 4.9% of atopic patients and 50.9% of subjects with Down syndrome. AN was more frequent in patients with severe AD and in 100% of cases of hand dermatitis and juvenile plantar dermatosis, located on the interphalangeal and metacarpophalangeal joints, whereas in Down syndrome other flexures were also affected. The pathogenesis of AN in AD is unknown, but in Down syndrome it seems to be related to obesity. Possible insulin resistance underlyng the pathogenesis of AN in these patients is still unknown.

We report two daughters of a Thai family affected with mental retardation, delayed speech, obesity, craniofacial manifestations, and ocular anomalies. Craniofacial manifestations included macrocephaly, maxillary hypoplasia, mandibular prognathism, and crowding of teeth. Ocular anomalies consisted of blepharophimosis, blepharoptosis, decreased visual acuity, abducens palsy, hyperopic astigmatism, and accommodative esotropia. Chronic atopic dermatitis, lateral deviation of the great toes, and cone-shaped epiphyses of the toes were observed. The disorder is suggested to be autosomal recessive. The combination of findings found in our patients has not hitherto been described.

Quality of life (QoL) in children and adolescents with bleeding disorders and their families is a relatively new topic. It is important to understand more about QoL in this patient population to evaluate and if necessary to improve the care patients receive. To achieve this aim, a questionnaire to assess patients' QoL in hemophilia was developed and psychometrically tested. Three hundred twenty hemophiliac children and adolescents from six European countries and their families were asked to fill out a questionnaire regarding different aspects of their well-being and functioning, as well as their views on hemophilia care. Generic QoL questionnaires showed that children with hemophilia have a higher QoL than other patients with chronic disease, such as asthma/atopic dermatitis and obesity. Several determinants affected patients' QoL (e.g., number of bleeds, social support). Parents' and children's assessments differed with regard to social and emotional aspects of QoL. The study showed that variations in QoL can be explained by clinical and psychosocial factors and suggested that QoL can be assessed and enhanced both by medical and non-medical (e.g., psychological) interventions.

The prevalence and factors associated with snoring and habitual snoring in Asian children are largely unknown. Our objectives were to evaluate the prevalence and factors associated with snoring and habitual snoring in preschool and primary school children in Singapore. A self-response questionnaire on snoring was administered to parents of children aged 4-7 years in randomly selected preschools and primary schools in Singapore. The overall response rate was 91.3% (nt = 11,114). Snoring and habitual snoring were reported in 28.1% and in 6.0% of the children, respectively. On multivariate logistic regression analysis, snoring was significantly associated with male gender, race, atopy (asthma, allergic rhinitis, or atopic dermatitis), maternal atopy (allergic rhinitis or atopic dermatitis), maternal smoking, and breastfeeding. Habitual snoring was significantly associated with obesity (odds ratio (OR), 3.75; 95% confidence interval (CI), 1.67-8.42), allergic rhinitis (OR, 2.90; 95% CI, 2.06-4.08), atopic dermatitis (OR, 1.80; 95% CI, 1.28-2.54), maternal smoking (OR, 2.22; 95% CI, 1.09-4.53), and breastfeeding (OR, 1.49; 95% CI, 1.11-1.98). Atopy was the strongest risk factor for habitual snoring, and the effect was cumulative. The odds ratio of a child with all three atopic diseases (asthma, allergic rhinitis, and atopic dermatitis) to have habitual snoring was 7.45 (95% CI, 3.48-15.97). In conclusion, snoring and habitual snoring are common in Asian children. Atopy is strongly associated with snoring and habitual snoring. We suggest that children who are significantly atopic receive additional attention during screening for snoring, habitual snoring, and other features of obstructive sleep apnea syndrome.

Health related quality of life (QoL) is a relevant criterion to understand well-being and function in children with chronic health conditions. Approaches to assessing quality of life are presented, based on a revision of the German KINDL questionnaire in the course of rehabilitation in three groups of chronically ill children (with diagnosis of asthma, atopic dermatitis or obesity), aged 8 to 17 years. Psychosocial and sociodemographic characteristics prior to, at the end and 12 months after rehabilitation were also assessed. At baseline, gender-, age- and diagnosis-specific impairments in QoL were found. Over time children improved, most clearly in children with obesity. Psychosocial predictors of QoL one year after rehabilitation were identified. The study shows that QoL assessment in children with chronic conditions is feasible and that children profit from rehabilitation programs. To further assess the QoL benefit in paediatric rehabilitation more studies are needed.

Breastfeeding is associated with decreased risk for many early-life diseases and conditions, including otitis media, respiratory tract infections, atopic dermatitis, gastroenteritis, type 2 diabetes, sudden infant death syndrome, and obesity. Breastfeeding also is associated with health benefits to women, including decreased risk for type 2 diabetes, ovarian cancer, and breast cancer. Exclusive breastfeeding is defined as an infant receiving only breast milk and no other liquids or solids except for drops or syrups consisting of vitamins, minerals, or medicines. In 2007, Healthy People 2010 (HP2010) objectives for breastfeeding initiation and duration were updated to include two new objectives on exclusive breastfeeding (i.e., to increase the proportion of mothers who exclusively breastfeed their infants through age 3 months to 60% and through age 6 months to 25% [objectives 16-19d and 16-19e]). To monitor progress toward achieving HP2010 breastfeeding objectives, CDC analyzed data from the National Immunization Survey (NIS). This report describes the results of that analysis, which indicated that rates for breastfeeding initiation and duration increased among infants born during 2000-2004. Rates for exclusive breastfeeding through ages 3 months and 6 months among infants born in 2004 were 30.5% and 11.3%, respectively, below targets set by HP2010. Rates of exclusive breastfeeding were significantly lower among black infants (compared with white infants) and infants born to unmarried mothers (compared with married mothers). Additionally, older age, urban residence, higher education, and higher income of mothers all were positively associated with exclusive breastfeeding. Further research is needed to identify successful programs and policies to support exclusive breastfeeding, especially among subgroups with the lowest rates.

Although the association between obesity and bronchial asthma (BA) has been gaining more attention, few studies have been conducted concerning the relationship between obesity and other allergic diseases. The objective of this study was to determine whether and how childhood obesity is associated with allergic diseases other than BA, such as atopic dermatitis (AD), allergic rhinitis (AR), allergic conjunctivitis (AC), and either AR or AC (AR/AC). A questionnaire was administered to the parents of 50,086 Japanese schoolchildren. Associations between childhood obesity and the various allergic diseases were evaluated by univariate and multivariate logistic models. Significant associations were found between higher body mass index (BMI) and AD (p = 0.03), and lower BMI and AC (p < 0.0001), and AR/AC (p < 0.0001). There was a significantly higher prevalence of BA in girls with obesity (p = 0.009) than in those without obesity. Significantly lower prevalence of AC (p = 0.01) and AR/AC (p = 0.002) among children with obesity, and AR (p = 0.04) and AR/AC (p = 0.0004) among boys with obesity were observed than those without obesity. Those who were obese and had AD were significantly more likely to have severe symptoms (p = 0.01). Overall, childhood obesity has positive associations with BA prevalence and AD severity, whereas it has negative associations with AR and AC prevalence, especially among boys. Changes in the immunologic balance accompanied by obesity might have different effects on each type of allergic disease. Exploring the mechanisms by which childhood obesity affects allergic status should lead to new management options for childhood allergy.

There is growing evidence for an association between obesity and asthma, but little is known about the underlying mechanisms. We hypothesized that high plasma leptin and low plasma adiponectin concentrations might be related to asthma and allergies in children. Plasma leptin and adiponectin concentrations were measured in a cross-sectional study involving 462 children aged 10 years. Information on disease symptoms and diagnosis was collected by parental questioning. Multivariate linear and logistic regression models were used to assess the association between biomarkers and disease. High leptin levels were associated with increased lifetime prevalence of asthma [odds ratio (OR): 3.76; 95% confidence interval (CI): 1.42-9.92]. The relationship was particularly strong for non-atopic asthma (OR: 5.51; 95% CI: 1.99-17.51). No associations were observed between plasma leptin levels and hay fever, and rhinoconjunctivitis. Low adiponectin levels were associated with increased prevalence of both symptoms of atopic dermatitis (OR: 3.23; 95% CI: 1.28-7.76) and ever-diagnosed eczema (OR: 2.35; 95% CI: 1.13-4.89). In girls and non-atopic children, stronger associations for both leptin and adiponectin levels with asthma than in boys and atopic children were observed. These results suggest that adipokines may contribute to increased asthma and allergy risk in obese subjects. Stronger associations among girls with non-atopic asthma may indicate diverse pathological mechanisms.
