Esophageal hiatal hernia is the hernia of a part of or the whole of stomach to posterior mediastinum through esophageal hiatus. Esophageal hiatal hernia can be classified as sliding hiatal hernia (type I), paraesophageal (type II), combined sliding and paraesophageal (type III), and complex paraesophageal (type IV). Type III and IV are clinically classified as paraesophageal hernia. The authors by chance found cystic mass filled with air in the lower lobe of the right lung during the treatment of mycoplasma pneumonia of 10 month-old patient. It was found to be paraesophageal hernia on the chest computed tomography and treated with the operation. As complex paraesophageal hernia is not usual among infants, the authors report it here with literature review.

PURPOSE: Recurrent otitis media (ROM) is usually defined as > or =3 distinct and well-documented episodes within 6 months or > or =4 episodes within 12 months. ROM is sufficiently important to warrant consideration of chemoprophylaxis, tympanostomy tube placement. There also is evidence that children with ROM are at risk for both hearing loss and speech delay. However, studies of ROM have been notably insufficient. In addition, even though environmental, racial, and sociocultural differences can affect risk factors, few studies have been conducted with regard to recurrent otitis media in Korea. METHODS: This study was conducted from July 2009 to January 2010 with infants and children who were younger than 60 months old, who visited the out-patient clinics at Han-Il General Hospital and Kyunghee University Hospital. Data were collected by interview using a pre-formed sheet. Among a total of 892 infants and children, 457 were excluded, and the remaining 435 were allocated to 104 with ROM and 331 as a control group. RESULTS: Attendance at daycare centers (P<0.001, OR=2.85), allergic rhinitis (P=0.026, OR=2.32), past history of bronchiolitis (P=0.003, OR=2.33), and low socioeconomic status (P=0.005, OR=2.00) were found to have a close significant correlation with ROM. Risk factors such as sex, having a sibling, breast-feeding, use of pacifiers, atopy, pneumococcal vaccination, influenza vaccination, smoking of parents, and indoor smoking are not relevant. CONCLUSION: Attendance at daycare centers, allergic rhinitis, past history of bronchiolitis, and low socioeconomic status have been identified as risk factors for ROM.

PURPOSE: Cough and wheezing are the most common respiratory symptoms in children. Recently, the cough-holter monitoring has been used to estimate the frequency and intensity of cough and wheezing, objectively. In this study, we aimed to evaluate the validity of cough-holter monitoring for the objective assessment of cough and wheezing in the hospitalized children with respiratory symptoms. METHODS: Cough-holter monitoring was performed in 59 children who suffered from cough and/or wheezing. We obtained the information on the frequency and intensity of cough and wheezing from the parents, a pediatrician, and cough-holter monitoring. Visual Analogue Scale (VAS) scores were taken by parents, and the pediatrician estimated the wheezing score by using a stethoscope. We assessed a relationship between the VAS scores, wheezing score, and cough-holter monitoring data. RESULTS: The frequencies and intensities of cough correlated positively with the VAS scores (r=0.301, P=0.032; and r=0.540, P=0.001, respectively) and the frequencies and intensities of wheezing also correlated positively with the Wheezing scores. (r=0.335, P=0.011; and r=0.457, P=0.001, respectively) The wheezing intensity did not correlate with the Wheezing score in wheezing children. (r=0.321, P=0.089) CONCLUSION: Cough-holter monitoring correlated positively with the VAS scores and the wheezing scores. Cough-holter monitoring appears to be a useful objective assessment tool for the children who have suffered from cough and/or wheezing.

PURPOSE: We examined whether fractional exhaled nitric oxide (FeNO) levels are associated with atopy profiles in terms of mono-sensitization and poly-sensitization in asthmatic children. METHODS: A total of 119 children underwent an assessment that included FeNO measurements, spirometry, methacholine challenge, and measurement of blood eosinophil count, serum total IgE, and serum eosinophil cationic protein (ECP). We also examined sensitization to five classes of aeroallergens (house dust mites, animal danders, pollens, molds, and cockroach) using skin prick testing. The children were divided into three groups according to their sensitization profiles to these aeroallergens (non-sensitized, mono-sensitized, and poly-sensitized). RESULTS: The geometric means (range of 1 SD) of FeNO were significantly different between the three groups (non-sensitized, 18.6 ppb [10.0-34.7 ppb]; mono-sensitized, 28.8 ppb [16.6-50.1 ppb]; and poly-sensitized, 44.7 ppb [24.5-81.3 ppb], P=0.001). FeNO levels were correlated with serum total IgE concentrations, peripheral blood eosinophilia, and serum ECP levels to different degrees. CONCLUSIONS: FeNO levels vary according to the profile of atopy, as determined by positive skin prick test results to various classes of aeroallergens. FeNO is also moderately correlated with serum total IgE, blood eosinophilia, and serum ECP. These results suggest that poly-sensitized asthmatic children may have the highest risk of airway inflammation.

OBJECTIVE: Recent molecular genetic studies have revealed that two major types of genomic instabilities, chromosomal instability and microsatellite instability (MSI), exist in the endometrial carcinomas. Tumors with microsatellite mutator phenotype (MMP) are caused by defects in DNA mismatch repair genes. MMP tumors are believed to progress by accumulating frameshift mutations in coding microsatellite sequences of various cancer related genes including tumor suppressor genes, apoptosis related genes and DNA repair genes. Thus, the identification of the specific target genes in the MMP endometrial carcinomas is important for the elucidation of molecular pathogenesis of endometrial carcinomas. METHODS: We classified the MMP endometrial carcinomas and evaluated the frameshift mutations of the 11 genes containing coding microsatellite sequences by using 34 endometrial carcinomas and 4 MMP endometrial carcinoma cell lines. RESULTS: MSI was found in 6 of 34 endometrial carcinomas. In the endometrial carcinoma tissues, frequent mutations were found in TAF1B (68%), HT001 (50%), SLC23A1 (50%) and ACVR II (50%) in the MMP endometrial carcinoma tissues. The other 7 genes were infrequently mutated. Mutations of these target genes were more frequent in MMP endometrial carcinoma cell lines. CONCLUSION: we identified specific target genes in MMP endometrial carcinomas. These data demonstrate the mechanism of tumor progression in the MMP endometrial carcinomas.
