Hyperimmunoglobulin E syndrome (HIES) is a rare immunodeficiency disease which is characterized by high serum IgE levels, eczema, and recurrent infections. Herein we present the case of a patient with HIES associated with STAT3 gene ($stat3$) mutation. A 16 year-old girl was admitted to our hospital due to hemoptysis caused by pneumonia with bronchiectasis. She had a history of recurrent skin and respiratory tract infections, such as pneumonia caused by MRSA (methicillin-resistant $Staphylococcus$ $aureus$) and $Pseudomonas$ $aeruginosa$. On physical examination, a broad round shaped nose, oral thrush, and chronic eczematous skin rash over her whole body were found. Laboratory data showed an elevated eosinophil count ($750/{\mu}L$) and total IgE level (5,001 U/mL). The patient's National Institutes of Health (NIH) score for HIES was 44. Direct sequencing of the STAT3 gene revealed that the patient was heterozygous for a missense mutation in the DNA binding domain of the STAT3 protein (c.1144C>T, p. Arg382Trp). HIES should be suspected in patients with recurrent infections and can be confirmed by clinical scoring and genetic analysis.

Purpose : Theophylline has recently been reported to have concurrent anti-inflammatory effects at low therapeutic plasma concentrations which are below the doses at which significants, clinically useful bronchodilatation is evident. Sustained-release formulation in capsule and dry syrup forms were developed to reduce its adverse effects and improve its clinical effects. We compared the therapeutic effects of theophylline dry syrup and capsules in children with mild asthma. Methods : Ninety children with mild asthma were randomized to receive either theophylline dry syrup (n=44) or theophylline capsules (n=46); 4 mg per kilogram of body weight, twice a day, for 12 weeks. Baseline and serial measurements of daytime and nighttime asthma symptom score were performed. Compliance scores, drug swallowing scores, and drug usability scores were measured every 4 weeks. Each scoring was rated on a scale of 0-4. Serum theophylline concentration were measured at 4 and at 12 weeks. To examine the anti-inflammatory effect of theophylline on asthma, Serum eosinophilic cationic protein as a marker of airway inflammation caused by eosinophil was measured 12 weeks pre- and post-administration. Results : The daytime and nighttime asthma symptom scores of the two groups after 4 weeks significantly improved over the baseline score. Daytime and nighttime asthma symptom scores in the dry syrup group were statistically lower at all time points except for the nighttime symptom scores at 4 weeks. Compliance scores, drug swallowing scores, and drug usability scores in the dry syrup group were significantly higher at the end time point. Only in the dry syrup group was the serum ECP at the end time point statistically lower than baseline. Conclusion : Low-dose sustained-release theophylline may be safe and effective in bronchial asthma and this effect may be mediated by its anti-inflammatory action mechanisms. Especially, when used in children with asthma, dry syrup formulation is recommended because of its higher compliance than capsule formulation.

Purpose : Recent reports pointed out that gonadotropin releasing hormone analogue (GnRHa) therapy alone is not so promising for improving adult height in precocious puberty. So, that we studied the growth promoting effect of combined therapy with GnRHa and growth hormone (GH) in early pubertal girls. Methods : Twenty three early pubertal girls ($9.73{\pm}1.59yr$) with predicted adult heights (PAH) below-2 standard deviation score (SDS) were included. They were divided into two groups as follows; Group I before menarche (n=19) and Group II after menarche (n=4). After combined therapy, various growth parameters were compared between two groups and between the before and after therapy. Results : Between the two groups before therapy, chronologic age (CA), growth velocity (GV), body mass index (BMI), target height (TH), PAH and serum insulin-like growth factor binding protein-3 were not different, but BA, height and difference between bone age (BA) and CA were significantly higher and insulin-like growth factor-1 (IGF-1) was marginally higher in group II. After therapy, BA still remained higher in group II, but other parameters were not different. In both groups, after therapy, the difference between BA and CA, the ratio of BA over CA, and GV were significantly decreased, but PAH, height SDS and BMI were significantly increased. Regarding IGF-1 level, a significant increase was noted in group I, but not in group II. Conclusion : With combined therapy of GnRHa and GH, PAH in early pubertal girls might be improved significantly and even approach TH. Among them, those who were before menarche might have greater potential for the height gain than those after menarche in view of IGF-1 changes during therapy.

This study was conducted to evaluate the effects of dietary softwood by-products extract on growth performance, organ weight and intestinal microbes in organic broiler chicks. Five treatments were assigned to 200 broiler chicks with four replication, allocating 10 broiler chicks in each replication. Dietary treatments included control(Organic diet), +C(Organic diet + antibiotics), T1(Organic diet + softwood by-product powder 3.0%), T2(Organic diet + softwood by-product extract 0.05%) and T3(Organic diet + softwood by-product extract 0.1%). Body weight gain was higher in +C and T3 for overall period than control and T1. Feed efficiency of were slightly improved in +C and T3 groups compared with that of control and T1. The small intestine weight tended to be higher in control and +C, but it's length showed high in only T1 group. Gizzard weight was significantly higher in T2 compared with other treatments(P<0.05). In contrast, spleen weight was significantly lower in control group(P<0.05), whereas the weight of cecum and liver were not significantly different by dietary treatment. Intestinal microflora was significantly lower or/and seemed to be low in softwood by-products treatment groups than control. Digestibility of energy and protein were statistically lower in control and T1 than other treatments(P<0.05). The IgG concentration of birds fed antibiotics, softwood by-product extract was higher than control and T1, but was no significance. The results of this experiments indicated that softwood by-product extract would be possible to apply for the feed additive in organic broiler diets.

Purpose : Continuous renal replacement therapy(CRRT) has been the first choice for the treatment of acute renal failure in critically ill children not only in western countries but also in Korea. However, there are very few studies that have analyzed the outcome and prognosis of this modality in Korean children. We performed this study to evaluate the factors associated with the outcome and prognosis of patients treated with CRRT. Methods : We retrospectively reviewed the medical records of 32 children who had received CRRT at Severance hospital from 2003 to 2006. The mean age was 7.5 years(range 4 days-16 years) and the mean body weight was 25.8 kg (range 3.2-63 kg). Results : Eleven(34.4%) of the 32 patients survived. Bone marrow transplantation and malignancy were the most common causes of death and underlying disease leading to the need for CRRT Mean patient weight, age, duration of CRRT, number of organ failures, urine output, estimated glomerular filtration rate(eGFR), C-reactive protein, and blood urea level did not differ significantly between survivors and nonsurvivors. (1) Pediatric risk of mortality(PRISM) III score at CRRT initiation($9.8{\pm}5.3$ vs. $26.7{\pm}7.6$, P<0.0001), (2) maximum pressor number ($2.1{\pm}1.2$ vs. $3.0{\pm}1.0$, P=0.038), and (3) the degree of fluid overload($5.2{\pm}6.0$ vs. $15.0{\pm}8.9$, P=0.002) were significantly lower in survivers than in nonsurvivors. Multivariate analysis revealed that fluid overload was the only independent factor reducing survival rate. Conclusion : CRRT was successfully applied to the treatment of acute renal failure in a wide range of critically ill children. To improve survival, we suggest the early initiation of CRRT to prevent the systemic worsening and progression of fluid overload in critically ill children with acute renal failure.

This study was conducted to determine the effect of probiotics as an alternative for antibiotics on growth performance, nutrient digestibility, noxious gas emission and fecal microbial population in growing piglets. A total of 96 piglets ($22.5{\pm}1.3$kg average body weight) were allotted to 3 different treatment groups and replicated 4 times with 8 piglets per replicate in randomized complete block design. Treatments were T1) (Control, basal diet+0.2% antibiotics), T2) 0.2% probiotics complex and T3) 0.3% Bacillus probiotics. During the whole experiment period, there were no differences (p>0.05) in average daily gain (ADG), average daily feed intake (ADFI) and feed efficiency. However, digestibility of dry matter, crude protein, ether extract, nitrogen free extract and crude ash were showed higher in probiotics groups (T2 and T3) than those of control. In noxious gas emission, ammonia, amine, hydrogen sulfide and mercaptan were significantly (p<0.05) reduced in T2 and T3 treatments compared to those in control. Moisture content of feces was not significantly different among treatments. The colony forming units (CFU) of total bacteria, E. coli and thermoduric bacteria in feces were significantly different among treatments. The CFU of total bacteria, E. coli and thermoduric bacteria in T3 treatment were reduced by feeding probiotics B. From this study, we suggest that probiotics A and B are likely able to improve the growth performance and nutrients digestibility, reduce noxious gas emission and change the fecal microbial composition in growing piglets.

Selenium is an essential micronutrient for normal body function and functions as an essential constituent of selenoproteins. This study was carried out to investigate effect of selenium on the formation of colonic aberrant crypt foci (ACF) and tumor formation in a mouse model. Five-week old ICR mice were acclimated for one week and fed different selenium diet (0.02, 0.1, and 0.5 ppm) for 12 weeks. Animals received three intraperitoneal injections of azoxymethane (10 mg/kg B.W. in saline for 3 weeks), followed by 2% dextran sodium sulfate in the drinking water for a week. There were four experimental groups, including a normal control group and three different selenium levels groups. After sacrifice, the total numbers of aberrant crypt (AC) and ACF were measured in the colonic mucosa after methylene blue staining. The number of tumors was noted for tumor incidence. Liver selenium concentration was measured using ICP-AES method. Gutathione peroxidase (GPx) activity was determined using a GPx assay kit in the liver and colon. TUNEL assay and proliferating cell nuclear antigen (PCNA) staining were performed to examine the cell apoptosis and cell proliferation, respectively. Immunohistochemistry of $\beta$-catenin was also performed on the mucous membrane tissue of colon. The activity of GPx in the liver and colon was decreased in the selenium-deficient diet group while it was increased in the selenium-overloaded diet group. Apoptotic positive cells were increased in the selenium-overloaded diet group but decreased in the selenium-deficient diet group. PCNA staining area was decreased in the selenium-overloaded diet group. In addition, the $\beta$-catenin protein level in the selenium-deficient diet group was increased but decreased in the selenium-overloaded diet group. These results indicate that dietary selenium might exert a modulating effect on colon cancer by inhibiting the development of ACF and colon tumor formation in this mouse model.

This study was conducted to determine the effects of dietary supplementation with probiotics on the growth and meat quality of finishing pigs. A total of forty eight ($Landrace{\times}Yorkshire{\times}Duroc$) pigs ($55.3{\pm}1.5 kg$ average initial body weight) were randomly assigned to four groups and fed on a diet supplemented with 0, 0.2, 0.5 or 1% probiotics for 58 days. The pigs were slaughtered at approximately 105 kg live weight. Supplementation with 0.2% probiotics significantly (p<0.05) increased daily gain compared to the control. The daily gain of pigs in the 0.2% probiotic group was 0.95 kg whereas that of the control was 0.85 kg. The average feed intake was 2.79-2.84 kg and there were no significant differences in feed intake between the control and test groups. The feed conversion of the 0.2% probiotic group was 2.96 kg whereas the control showed a feed conversion of 3.28 kg. The results of this study imply that supplementation with 0.2% probiotics may improve the feed conversion of pigs. There were significant differences in carcass weight, carcass ratio, backfat thickness, and frequency percentage of A grade carcasses between the control and probiotic test groups. In addition, the moisture, crude protein and crude ash contents of the probiotic treated groups did not differ significantly from the control group, however the crude fat values of the 0.2% probiotic test group was significantly tower than the other groups. The muscle pH levels of all samples ranged from 5.63-5.67 which is the normal pH of pork. The supplementation of probiotics resulted in decreased lightness ($L^*$) values and increased redness ($a^*$) values. Furthermore, the saturated fatty acid contents of the 0.2% and 0.5% probiotic test groups decreased and the unsaturated fatty acid contents increased relative to the control.

Purpose : The aim of this study was to evaluate whether the incidence of relapse or nephritis might be influenced by the duration of corticosteroid therapy in children with Henoch-Schonlein purpura(HSP). Methods : We retrospectively analyzed 186 children with a diagnosis of HSP in two major hospitals in Ilsan, Korea from the years 2000 to 2003. To evaluate whether renal involvement or relapse might be influenced by the duration of corticosteroid therapy in children with HSP, one pediatric nephrologist from hospital A, maintained corticosteroid therapy for at least 2 weeks(Group A, n=94). The other from hospital B used only during the symptomatic period(Group B, n=92). Results : There were no significant differences in age, sex, body weight, white blood cell count, hemoglobin, hematocrit, platelet count, serum protein and albumin levels between the two groups. The incidence of abdominal pain or arthralgia also did not differ between two groups. However, the duration of steroid therapy was significantly longer in Group A than in Group B and the cumulative dose of prednisolone was also higher in Group A than in Group B. The development of nephritis was more frequent in Group A. Conclusion : The longer duration of steroid use was not associated with the decreased rate of nephritis. Therefore, corticosteroids should be used carefully in a selected group of HSP children, and be tapered rapidly after control of the acute symptoms.
