BACKGROUND AND OBJECTIVES: Crying is the only mode of communication, which simultaneously reflects a variety of complex neurophysiologic and laryngeal functions in neonates. Acoustic analysis of crying, as an early noninvasive screening measure of the neurophysiological integrity, can reveal important information about the biological status of neonate. The purpose of this research was to establish normative acoustic data on healthy neonatal crying. This study also attempted to find out the differences in the pattern of healthy neonatal crying according to body weight, sex and delivery type (normal spontaneous vaginal delivery and Cesarean section). SUBJECTS AND METHOD: Crying of 33 healthy full term neonates (19 males, 14 females) were sampled within 1 wk postpartum. All neonates were free of any respiratory, laryngeal, CNS pathology according to the charts reviewed at one month. All neonates were considered to have normal hearing as they passed a hearing screening test using Evoked Otoacoustic Emission (EOAE). Body weight, sex, delivery type and Apgar score (1 min, 5 min) were measured. The acoustic characteristics of neonatal crying were analyzed by CSL (Computerized Speech Lab) using parameters such as fundamental frequency (F0), Jitter (%), Shimmer (%), NHR and formant frequency (F1, F2, F3). Statistics were analyzed by independent T-test, pearson's correlation coefficients (p<0.05, by SPSS ver 10.0). RESULTS: Mean body weight and Apgar score (1 min, 5 min) of all subjects were within normal range. Mean fundamental frequency (F0) value of healthy full term neonatal crying was 411.1 Hz. This value showed a shift to higher frequencies in neonates born by spontaneous vaginal delivery (SVD) than Cesarean section (C-sec) delivery, and so, in males than females. But statistic significance in F0 between delivery types, and between sex were not found (p-value 0.158, 0.508). Mean Jitter (%), Shimmer (%) and NHR value were 2.02, 8.34 and 0.32, respectively. These values showed a shift to higher in neonates born by C-sec delivery than SVD, and also in males than females. But statistical significance in these parameters between delivery types, and between sex were not found (p-value 0.442, 0.841, 0.301, 0.082, 0.070, 0.244). Formant frequency F1, F2 and F3 were 1882.4 Hz, 3877.9 Hz and 6053.6 Hz, respectively. There was no statistically significant difference in these values between sex, and delivery types (p-value 0.619, 0.785, 0.953, 0.255, 0.698, 0.636). For the healthy full term neonates, F0 value had a tendency to decrease as the body weight increases. But there was no significantly strong negative correlations between them. (r=-0.324, p-value 0.066). Other acoustic parameters didn't show any statistically significant relevance with body weight, either. CONCLUSION: Body weight, sex and delivery type had little influence over acoustic parameters of healthy full term neonatal crying. However, this acoustic analysis of crying could be helpful in differentiating between normal and abnormal neonates, and in screening CNS dysfunction, neurophysiologic and laryngeal abnormality.

BACKGROUND AND OBJECTIVES: Magnetic resonance (MR) imaging has resulted in a tremendous advance in the technology of medical diagnosis. However, even with all positive advances, there are usually some negative aspects, especially noise. It is well known that loud sounds can induce a hearing loss. This study was performed to determine the acoustic characteristics of MRI noise and whether or not the sound exposure resulting from routine MRI examinations is capable of altering the auditory thresholds of patients. MATERIALS AND METHOD: Digital Impulse Sound Level Meter was placed at patient's head level and at a 2m distance. Frequency of MRI noise was recorded by Digital audio tape and analyzed by Computerized Sound Lab (CSL). A total of 53 adults (106 ears) who were scheduled for MR imaging studies were included in the study. Pure-tone air-conductive auditory threshold was determined bilaterally in each patient before and after MRI. RESULTS: The noise levels at head level ranged from 80.8 dB to 86.0 dB, and at a 2 m distance, from 71.9 dB to 75.9 dB. The frequency ranged from 60 Hz to 2500 Hz. Nine of the 106 ears had a hearing loss of at least 10 dB at one frequency. CONCLUSION: The noise generated by the MRI is sufficiently intense to cause some temporary threshold shifts (TTS). TTS may transform to permanent threshold shifts. Therefore, it is important to devise a method to minimize the risk of these shifts, for example, by using earplug.

BACKGROUND AND OBJECTIVES: The objective of this article is to evaluate the effectiveness and the compliance rates of immunotherapy, and to identify the factors affecting the compliance of immunotherapy. SUBJECTS AND METHOD: We evaluated the charts of 120 patients with allergic rhinitis and/or asthma, for which allergen immunotherapy was carried out from 1998 and 2000. Information was obtained via chart reviews and telephone surveys. RESULTS: Among the 120 patients with allergic rhinitis, 41 patients also had asthma. The common allergens identified by the skin prick test prior to immunotherapy were D. farinae, D. pteronyssinus, dog fur, cat fur, and cockroaches, et al. The skin prick test reactivity to common allergens is significantly lower after three years of immunotherapy than it is prior to immunotherapy. The satisfaction of patients after immunotherapy between the allergic rhinitis group and allergic rhinitis with asthma group are as follows: much satisfied (25.4%/27.3%), fairy satisfied (31.6%/33.7%), a little satisfied (15.2%/17.2%), not satisfied (17.1%/13.3%), and unsure (10.7%/8.5%). In our study, the compliance rates of immunotherapy were 65.7%. The reasons cited for discontinuance of allergen immunotherapy were inconvenience (45%), lack of improvement in symptoms (23%), improvement in symptoms (15%), greater improvement in symptoms through medication (11%), and other reason (7%). CONCLUSION: If we increase the compliance of immunotherapy through various researches on the compliance of immunotherapy and educating patients about it, allergen immunotherapy may become more effective in treating allergic disorders.

BACKGROUND AND OBJECTIVES: Although children's personality and behavior change caused by adenotonsillar hypertrophy have been thought to significantly relate with children's growth and learning capability, it has not been substantiated by any available standarized assessment. We aim to uncover the impact of adenotonsillar hypertrophy on children's personality and behavior by K-CBCL (Korean Child Behavior Checklist) and KPI-C (Korean Personality Inventory for Children). MATERIALS AND METHOD: Children aged 5 through 15 years old, a total of 33 (M: 18 F: 15) who were scheduled for T & A (Tonsillectomy and Adenoidectomy), were studied. The control group consisted of 42 healthy children (M: 22 F: 20) of the same age. Two standard questionnaires, K-CBCL and KPI-C, were given to the parents of the children to complete and then a statistical analysis carried out by a clinical psychologist for interpretation (p<0.05, by SPSS v10.0). RESULTS: According to K-CBCL, internalizing problems and total behavior problems were of statistical significance for the patient group compared to healthy children (p<0.05). KPI-C test revealed statistical significance on ERS (ego resilience scale), ANX (anxiety), SOM (somatization) and FAM (familial relationship)(p<0.05). In both groups, the results between gender were quite different. In female patient group, the total behavior problems were indicated, while in the male patient group, the total behavior problem, internalizing problem as well as somatic complaints were indicated. Especially, indications of ERS and SOM were of statistical significance (p<0.05). CONCLUSION: Children with adenotonsillar hypertrophy have difficulty in adaptation, and lack the ability to respond to situation, and easily get broken down by stress, and experience frequent anxiety.

Duodenal duplication cysts are rare congenital malformations. Most symptomatic cases are diagnosed in children and usually present with obstructive findings or bleeding symptoms. Treatment traditionally involves surgical resection, which can be often difficult because of the close proximity of the cysts to the papilla and bilopancreatic confluence. Endoscopic therapy has been used as an alternative to open surgery in a few selected cases. We report a case with a duodenal duplication cyst containing a brown pigmented stone within the cystic lumen. He was visited because of sudden right upper quadrant abdominal pain. An abdominal computed tomography revealed the presence of a cyst with a stone, which was finally removed by endoscopic resection.

BACKGROUND/AIMS: The inadequacy of information on the treatment of gastric candidiasis with antifungal agents promoted us to evaluate patients with fungal infections who had gastric ulcers and assess the need for proton-pump inhibitors or antifungal agents. METHODS: Sixteen patients were included in the study. The criterion for the diagnosis of candidiasis was finding yeast and hyphae in the tissue or an ulcer on histological sections of biopsy samples. Surface fungi were not considered infections. RESULTS: In all cases with benign ulcers, follow-up endoscopy performed 6 weeks after proton-pump-inhibitor treatment revealed that the ulcer had improved without antifungal medication. However, in patients with malignant ulcers, surgical resection was necessary for a definitive cure. Two patients with lymphoma received combined chemotherapy and a proton-pump inhibitor, which improved their condition. CONCLUSIONS: The results of this study suggest that benign ulcers with candidiasis can be effectively treated by a proton-pump inhibitor without antifungal medication. However, surgical resection should be considered for malignant ulcers with candidiasis.

Transjugular intrahepatic portosystemic shunt (TIPSS) is a promising method of treatment for gastric or esophageal variceal bleeding. This study was performed to determine the prognostic factors contributing to the survival of patients after TIPSS for gastric or esophageal variceal bleeding. One hundred and fifty-five patients who underwent TIPSS between September 1991 and March 2001 were followed up by clinical examination, upper gastrointestinal endoscopy, and Duplex sonography. The mean portohepatic pressure gradient prior to TIPSS was 20.5 +/-9.93 mmHg and dropped to 10.7 +/-6.62 mmHg after TIPSS (p<0.001). The cumulative survival rate was 75.1% at 6 months, 66.6% at 1 yr, 58.4% at 2 yr, and 38.1% at 5 yr. Survival after TIPSS was inversely related to the Child-Pugh classification (p<0.05). The rebleeding rate was 18.3% at 6 months, 21.0% at 1 yr, 32.8% at 2 yr, and 53.1% at 5 yr. The causes of deaths were hepatic failure (53.5%), recurrent variceal bleeding (11.6%), pneumonia (4.6%), sepsis (3.5%), hepatic encephalopathy (2.3%), and unknown (17.4%). Multivariate analysis (Cox proportional hazard model) revealed that the Child-Pugh classification and age were statistically significant independent prognostic factors. In conclusion, TIPSS is an effective method of treatment for variceal bleeding in cases where other treatment modalities including endoscopic therapy are unsuccessful and the most important prognostic factors are preprocedural hepatic reserve (Child-Pugh class) and age.

Rendu-Osler-Weber disease is characterized by hereditary transmission, and by the presence of multiple telangiectases of the skin, mucous membranes, and internal organs. We present a case of Rendu-Osler-Weber disease with bleeding from gastric telangiectases that was successfully treated by endoscopy with the use of argon plasma coagulation (APC). A 65-year-old woman presented with melena. Endoscopy disclosed multiple telangiecatses in the whole stomach. APC was performed at an output of 50 W and with an argon gas flow rate of 2 L/min. Only multiple ulcers at the treated sites were seen 7 days after the procedure and fibrotic scars with contracted mucosal folds without active bleeding signs were noted 2 months later.

A lymphoepithelial cyst of the pancreas is a rare, benign disease. A 58-year-old man with no abdominal symptoms was found to have a cystic mass in the pancreas. Computed tomography showed a multi-septated cystic mass in the tail of the pancreas. We performed a distal pancreatectomy with a splenectomy. Histological examination revealed that the cyst wall was lined with squamous epithelium and surrounded by lymphoid tissue. Keratinous material was present in the cyst. A lymphoepithelial cyst of the pancreas should be considered in the differential diagnosis of all cystic pancreatic lesions. Fine-needle aspiration biopsy may be a useful strategy, but local surgical resection of the cyst, for most patients, should be considered to exclude malignancy.

PURPOSE: In spite of many reports about Helicobacter pylori infection in children with functional gastrointestinal disorders, there are few reports about the influence of H. pylori infection to functional dyspepsia and gastric motility. Therefore, we studied the influence of H. pylori infection on gastric myoelectrical activity in children with functional dyspepsia. METHODS: Between August 2006 and December 2008 upper gastrointestinal endoscopies with biopsies, the rapid urease test and/or 13C urea breath test, and electrogastrography (EGG) were performed on 63 patients with histologic chronic gastritis; patients with chronic disorders were excluded. Comparisons about gastric myoelectrical activities were made between H. pylori-positive children (n=25) and H. pylori- negative children (n=38). RESULTS: The percentage of pre- and post-prandial normogastria was relatively lower in H. pylori-positive children than H. pylori-negative children (80% vs. 65%, and 80% vs. 68%, respectively). Compared to H. pylori-negative children, H. pylori-positive children had lower postprandial predominant power (8.18+/-22.36 dB and 32.20+/-24.18 dB, respectively; p<0.01) and a lower power ratio (deltaP; delta1.28+/-6.18 vs. +.62+/-5.93, respectively; p<0.01). CONCLUSION: It was suggested that the gastric myoelectrical activity in children with chronic gastritis can be influenced by H. pylori infection. Thus, this study indicates that H. pylori infection may be predictable in children with functional dyspepsia through analyzing the EGG parameters, and treatment may be considered in H. pylori-positive children with impaired gastric activity, especially in the lower prevalence area.
