Background: The influence of food avoidance due to allergic symptoms in infancy on the growth of children at school age has not been well evaluated. Methods: To determine the growth of schoolchildren who avoided eggs, milk, or wheat due to immediate allergic symptoms in infancy (food avoiders in infancy) (FAI), a questionnaire on the presence of allergic diseases, as well as present height and weight, was administered to the parents of 14,669 schoolchildren. 11,473 subjects had available data. The height and weight standard deviation scores (HtSDS and WtSDS) and body mass index percentile (BMI percentile) of each subject were calculated. Results: FAI had significantly lower WtSDS than non-FAI (P = 0.01). Among those with avoidance at age 3 years, those who avoided two or more foods and those who avoided milk had significantly lower HtSDS than their counterparts (P = 0.02 and 0.04, respectively). FAI had a significantly lower prevalence of obesity (P = 0.01) and overweight (P = 0.002), while there was no difference in the prevalence of underweight (P = 0.58), resulting in a significantly higher prevalence of appropriate weight (P = 0.01) compared to non-FAI. Significantly lower prevalence of obesity and overweight was observed even among those who terminated the avoidance by age 3 years. Conclusions: FAI were less likely to be obese or overweight, resulting in a higher prevalence of appropriate weight at school age. Further investigation should contribute to better management of food allergy and obesity.

Background: Published data regarding changes in the prevalence of childhood allergic diseases in Japan have been limited. Methods: To observe changes in the recent trends of the childhood allergy epidemic in Japan, a population- based questionnaire survey of allergic diseases was conducted among 13,215 schoolchildren, aged 7 to 15 years, in Kyoto, Japan in 2006. The results were compared with those obtained in the 1996 survey using the same scale and methods in the same region. Results: The prevalences of bronchial asthma (BA), atopic dermatitis (AD), allergic rhinitis (AR), and allergic conjunctivitis (AC) in 1996 and 2006 were 5.1% and 5.0% (p = 0.58), 4.2% and 5.6% (p < 0.0001), 20.3% and 27.4% (p < 0.0001), and 13.3% and 25.2% (p < 0.0001), respectively. Although the distribution of BA severity improved, the severity distribution of AD, AR, and AC all deteriorated. The lifetime prevalence (present prevalence and past history combined) of BA increased from 6.5% to 7.6% (p < 0.0001). The sex ratio analysis showed that the female predominance in the prevalence of AD observed in 1996 disappeared in 2006, indicating a particular rise in AD prevalence among boys. Conclusions: Overall, the results indicate that the rising trend of allergic diseases, especially in AD, AR, and AC, continues among schoolchildren living in Kyoto, Japan. Special attention should be paid to skin and naso- ocular symptoms.

Monocytes/macrophages have recently been shown to play a significant role in the pathogenesis of allergic diseases. As the level of soluble CD14 (sCD14) in serum is considered a marker of monocyte/macrophage activation, we measured the levels of sCD14 in allergic asthma and atopic dermatitis (AD), along with acute infectious and inflammatory diseases, to see its clinical relevance. Serum samples were taken from patients with acute infectious and inflammatory diseases, allergic asthma, and atopic dermatitis. sCD14 was measured with our own ELISA system and its level in each disease was compared with normal controls as well as its disease severity. sCD14 was elevated and correlated with C-reactive protein in infectious and inflammatory diseases (n = 26), confirming that it reflects inflammation. sCD14 was also significantly increased both in asthma (n = 94) and adult chronic AD (n = 22). In asthmatic patients, those with higher sCD14 tended to have more severe symptoms, but there was no statistical correlation between sCD14 and severity. In adult chronic AD patients, a correlation between sCD14 and disease severity was observed. However, sCD14 was not elevated in infant AD patients (n = 18) irrespective of severity, suggesting differences in the degree of monocyte/macrophage involvement in the pathogenesis between adult chronic and infant AD. The levels of sCD14 were shown to be upregulated in allergic diseases and might be useful as a marker of monocyte/macrophage involvement in allergic inflammation.

- Abstract
In Japan, the rate of low birth weight infants has increased, due to an increase in the number of women who smoke or are lean. A recent study showed that low birth weight was associated with a high adult waist-to-height ratio in adult Japanese women, but little data is available concerning children. In this cross-sectional study with 568 subjects (276 boys and 292 girls), we examined the association between birth weight and waist-to-height ratio in 7- or 8-year-old Japanese children, all born at full term. The mothers of the subjects responded to a questionnaire about the weight of the children at birth, and physical data were collected from the results of measurements conducted at each school. We divided the subjects into two groups by the median of the birth weight (3,000 g) by sex to elucidate the effects of birth weight on the waist-to-height ratio. There were 119 boys and 164 girls and 157 boys and 128 girls in the < 3,000 g and ≥ 3,000 g birth weight groups, respectively. The Mann-Whitney U test was used to compare the physical conditions in the two birth weight categories. Height was significantly lower in the birth weight < 3,000 g group among both the boys (P < 0.001) and girls (P < 0.001). The waist-to-height ratio was significantly higher in the < 3,000 g group in girls (P = 0.004), but not in the boys. Our results suggest that intrauterine environmental insults might have an effect on children, depending on sex. [ABSTRACT FROM AUTHOR]

Febrile infection-related epilepsy syndrome (FIRES) is a severe epileptic syndrome that manifests with refractory seizures or status epilepticus in previously healthy children after banal febrile illness. The neuroimaging findings in the acute phase of FIRES are nonspecific or normal. We report the case of a 7-year-old boy with FIRES who presented with a reversible lesion in the splenium of the corpus callosum on brain magnetic resonance imaging (MRI). The patient developed clusters of clonic seizures with a deviation of the eyes after a 3-day history of fever. A reversible splenial lesion was observed on brain MRI and, therefore, the initial diagnosis was mild encephalitis/ encephalopathy with a reversible splenial lesion (MERS). However, the intractable complex partial seizures necessitated a long-term midazolam infusion, indicating that FIRES was a more likely diagnosis than MERS. All other findings of this patient met the diagnostic criteria for FIRES.With this diagnosis, a high-dose phenobarbital was administrated, and the seizures were successfully controlled. This case indicated that FIRES should be considered even in patients with a reversible splenial lesion associated with encephalitis/encephalopathy. [ABSTRACT FROM AUTHOR]

- Abstract
Abstract Osteolytic lesions are rapidly progressive during the terminal stages of myeloma, and the bone pain or bone fracture that occurs at these lesions decreases the patients’ quality of life to a notable degree. In relation to the etiology of this bone destruction, it has been reported recently that MIP-1α, produced in large amounts in myeloma patients, acts indirectly on osteoclastic precursor cells, and activates osteoclasts by way of bone-marrow stromal cells or osteoblasts, although the details of this process remain obscure. In the present study, our group investigated the mechanism by which RANKL expression is induced by MIP-1α and the effects of MIP-1α on the activation of osteoclasts. RANKL mRNA and RANKL protein expressions increased in both ST2 cells and MC3T3–E1 cells in a MIP-1α concentration-dependent manner. RANKL mRNA expression began to increase at 1 h after the addition of MIP-1α; the increase became remarkable at 2 h, and continuous expression was observed subsequently. Both ST2 and MC3T3-E1 cells showed similar levels of increased RANKL protein expression at 1, 2, and 3 days after the addition of MIP-1α. After the addition of MIP-1α, the amount of phosphorylated ERK1/2 and Akt protein expressions showed an increase, as compared to the corresponding amount in the control group. On the other hand, the amount of phosphorylated p38MAPK protein expression showed a decrease from the amount in the control group after the addition of MIP-1α. U0126 (a MEK1/2 inhibitor) or LY294002 (a PI3K inhibitor) was added to ST2 and MC3T3-E1 cells, and was found to inhibit RANKL mRNA and RANKL protein expression in these cells. When SB203580, a p38MAPK inhibitor, was added, RANKL mRNA and RANKL protein expression were increased in these cells. MIP-1α was found to promote osteoclastic differentiation of C7 cells, an osteoclastic precursor cell line, in a MIP-1α concentration-dependent manner. MIP-1α promoted differentiation into osteoclasts more extensively in C7 cells incubated together with ST2 and MC3T3-E1 cells than in C7 cells incubated alone. These results suggested that MIP-1α directly acts on the osteoclastic precursor cells and induces osteoclastic differentiation. This substance also indirectly induces osteoclastic differentiation through the promotion of RANKL expression in bone-marrow stromal cells and osteoblasts. The findings of this investigation suggested that activation of the MEK/ERK and the PI3K/Akt pathways and inhibition of p38MAPK pathway were involved in RANKL expression induced by MIP-1α in bone-marrow stromal cells and osteoblasts. This finding may be useful in the development of an osteoclastic inhibitor that targets intracellular signaling factors. [ABSTRACT FROM AUTHOR]

Chronic infantile neurologic, cutaneous, articular syndrome (CINCA syndrome) is a severe inflammatory disease that was recently found to be associated with mutations in CIAS1. However, CIAS1 mutations have been detected in only half of CINCA syndrome patients, and it remains unclear which genes are responsible for the syndrome in the remaining patients. We describe here a patient with CINCA syndrome who exhibited CIAS1 somatic mosaicism. We genetically analyzed the CIAS1 gene in various blood cells and the buccal mucosa of the patient. The production of interleukin‐1β (IL‐1β) by peripheral blood mononuclear cells (PBMCs) was measured by enzyme‐linked immunosorbent assay, and the ability of the mutant CIAS1 gene to enhance ASC‐dependent NF‐κB activation was assessed to confirm that the mutations of CIAS1 found were responsible for the patient's clinical manifestations of the CINCA syndrome. The patient had 1 heterologous single‐nucleotide polymorphism, 587G>A (S196N), and 1 heterologous mutation, 1709A>G (Y570C), in exon 3 of CIAS1. The latter mutation was found to occur as somatic mosaicism. The patient's PBMCs produced a large amount of IL‐1β in the absence of stimulation, unlike those from controls or from his mother, who also bore the S196N polymorphism. In addition, the Y570C mutation (with or without the S196N polymorphism) increased the ability of CIAS1 to induce ASC‐dependent NF‐κB activation, unlike the wild‐type gene or the gene bearing the S196N polymorphism alone. The findings in this patient indicate that somatic mosaicism is one reason CIAS1 mutations have not been detected in some patients with CINCA syndrome. [ABSTRACT FROM AUTHOR]
