BACKGROUND AND OBJECTIVES: Uvulopalatal flap (UPF), which is a modification of UPPP, is established in the treatment of snoring and obstructive sleep apnea syndrome (OSAS) with reduced velopharyngeal incompetence (VPI) risk. This study was performed to evaluate the subjective outcome of UPF among patients with simple snoring or obstructive sleep apnea. MATERIALS AND METHODS: Twenty patients with OSAS were examined (sixteen male, four female) in a prospective manner. Subjects who underwent UPF have completed pre or post operative (after 3 months) polysomnographic (PSG) studies. The parameters of PSG were apnea index (AI), respiratory disturbance index (RDI), mean SaO2, and lowest SaO2. Questionnaires composed of Eworth sleepiness scale (ESS) and snoring symptoms inventory (SSI) were completed by patients and bed partner before and after the UPF. Statistical analysis was performed using the Wilcoxon signed rank test. RESULTS: Subjective questionnaires indicated statistically significant improvements (SSI ; from 60.9 to 37, ESS ; from 11.6 to 7.4). The AI decreased from 18.6 to 9.3, RDI decreased from 29.8 to 16.6 (p<0.05). CONCLUSION: UPF seems to be more effective in mild OSAS than in moderate and severe OSAS. Long term follow up studies with more patients is deemed necessary.

BACKGROUND: Chronic cough is commonly defined as a persistent or recurrent cough exceeding 3 weeks duration and the prevalence of chronic cough is reported to range from 14-23% among non-smoking adults. Irwin et al previously reported that common causes of chronic cough are postnasal drip syndrome asthma, and gastroesophageal reflux using the anatomic and diagnostic protocol. OBJECTIVE: To determine the spectrum and frequency of chronic cough and to aid establishing algorithmic approach for chronic cough. MATERIALS AND METHOD: We prospectively evaluated 105 consecutive and unselected immunocompetent patients complaining of chronic cough utilizing modified anatomic and diagnostic protocol proposed by Irwin et al. Initial diagnosis was made by history, physical examination and laboratory test including spirometry, methacholine provocation test, and 24 hour pH monitoring. Specific treatment was done based upon initial diagnosis and cough score was compared before and after treatment. Reassessment was done in case of treatment failure. RESULT: The causes of cough were determined in 100 of 105 patients(95% ). Cough was due to one condition in 94.8% and two in 15.2%. 121 causes of cough were identified and their spectrum and frequency were found to be postnasal drip syndrome (39.3% ), asthma (32.2% ), gasteroesophageal reflux (14.1%), chronic bronchitis (5.0%), others (4.1%: drug-induced, bronchiolitis, endobronchial tuberculosis, and lung cancer). History about nasal symptoms was useful, but history about gastroesophageal reflux were not useful for the diagnosis. CONCLUSION: The results suggest that anatomic and diagnostic approach for evaluating chronic cough is also useful in Korea and the most common causes of chronic cough are postnasal drip syndrome, asthma and gastroesophageal reflux.

Verrucous carcinoma, an atypical variant of squamous cell carcinoma that is well-differentiated, is known to invade locally with rare metastasis. It was first reported by Ackerman in 1948 and has been reported in the areas of the head and neck and the external genitalia. A case of endonasal verrucous carcinoma was first reported by Krause. Cases of the sinus were reported to have occurred in the ostium of maxillary sinus and frontal sinus, and there has also been a reported case of a verrucous carcinoma that invaded the subnasal, which originated from the hard palate. However, no such case of verrucous carcinoma invasion originating from the nasal vestibule has been reported. Verrucous carcinomas are often clinically malignant, yet pathohistologically benign, thus, unlike most squamous cell carcinomas, they are of a low-risk group with rare metastasis, few recurrences, and good prognosis with proper treatment. In some cases of verrucous carcinoma treated with radiotherapy, anaplastic variations occur, thus surgical removal is known to be the treatment of choice. The authors report a recent case of verrucous carcinoma that originated from the nasal vestibule which was surgically removed and treated with adjuvant radiotherapy.

Garlic and mugwort have long been used in traditional medicine to prevent various diseases. Several in vitro studies have reported protective efficacies of garlic and mugwort in cases of gastric cancer. In the present study, we investigated the cancer preventive effects of garlic and mugwort mixture extract (GME) in a Helicobacter (H.) pylori-associated gastric carcinogenesis mouse model. To induce gastric cancer, C57BL/6 mice were treated with N-methyl-N-nitrosourea and H. pylori. Various concentrations of GME (0, 100, 500, and 1,000 ppm) were then fed to the mice for 38 weeks, after which the tumor tissues were examined for histopathology, mucin histochemistry and beta-catenin. The incidence of gastric tumors was significantly lower in the highest dose GME-treated mice (46.7%) than control mice (85.7%) (p < 0.05). The multiplicity and size of tumors were also significantly reduced by GME feeding in a dose-dependent manner (p < 0.01). Furthermore, GME suppressed the H. pylori-associated chronic inflammation measured by histologic grading of H. pylori density, chronic gastritis, glandular atrophy and intestinal metaplasia in non-tumorous gastric mucosae. Our data suggest that GME suppresses gastric tumorigenesis via suppression of H. pylori-associated chronic inflammation.

OBJECTIVE: To assess the effect of single-dose cisplatin intraperitoneally administered during cytoreductive surgery in advanced epithelial ovarian cancer. METHODS: Data from patients who underwent surgical management followed by intravenous (IV) chemotherapy for stage III epithelial ovarian cancer from 2003 to 2012 were retrospectively reviewed. Subjects were divided into intraperitoneal (IP) and no-intraperitoneal (NIP) groups according to the administration of IP cisplatin 100 mg during the staging surgery. Clinical results such as survival outcomes and chemotherapeutic toxicity were compared between the two groups. RESULTS: Thirty-seven patients in the IP group and 26 in the NIP group were identified. There were no significant differences between the two groups in basic characteristics such as age, histology, and surgical procedures. After the surgery with or without IP chemotherapy, there was no difference in the rate of either hematologic or gastrointestinal toxicity or in the rate of incompletion of following IV chemotherapy. Tumor recurrence occurred in 67.6% (25 patients) of IP group and 57.7% (15 patients) of NIP group (P=0.423) during the mean follow-up period of 37 months. The 3-year disease free-survival rate was 39.9% in the IP group and 35.8% in the NIP group, and the relative risk of recurrence was 0.864 (95% confidence interval, 0.447-1.673; P=0.665) in the IP group as compared with the NIP group. CONCLUSION: IP chemotherapy with single-dose cisplatin during cytoreductive surgery is safe and feasible with little chemotherapeutic toxicity in advanced epithelial ovarian cancer, but no distinct improvement in survival could be demonstrated in the present study.

OBJECTIVE: The primary aim of this study was to investigate the acute impact of methylphenidate (MPH) on sleep parameters in attention-deficit/hyperactivity disorder (ADHD) children. The second aim was to investigate the different effects of intermediate- and longacting MPH on sleep parameters. The third aim was to test the different effects of dose and age on sleep parameters. METHODS: Ninety-three ADHD children were enrolled and randomized to two different MPH preparations. Baseline and daily sleep diaries were evaluated for four weeks after taking medication. Weekday and weekend bedtimes, wake-up times, sleep latencies and total sleep times were compared by weeks. RESULTS: After taking MPH, there was a significant delay in bedtimes and a significant reduction of total sleep time (TST) both on weekdays and at weekends. There was also a significant delay in wake-up time on weekdays. However, the difference was applied to younger age group children only. There was no difference in changes of TST between metadate-CD and OROS-MPH. There also was no difference in changes of TST with different doses of MPH. CONCLUSION: MPH had negative impacts on sleep among young ADHD children, but different preparations and doses did not affect the result.

It has been demonstrated that spider mites such as the two-spotted spider mite (Tetranychus urticae) are important allergens for fruit farmers. A total of 2,467 adults (795 metropolitan urban, 788 non-metropolitan urban, and 884 rural subjects) were enrolled. They responded to the questionnaire, and underwent methacholine bronchial provocation tests as well as skin prick tests to locally common aeroallergens including the two-spotted spider mite. The prevalences of asthma and rhinitis as reported on the questionnaire were 7.8% and 16.4% of adults aged 20-35, 9.4% and 24.7% of those 36-50, and 17.7% and 21.7% of those older than 50, respectively. Among the older group, the two-spotted spider mite was the most common sensitizing allergen, although it was second of that of house dust mites among the other two age groups. Sensitization to the two-spotted spider mite was significantly associated with the prevalence of asthma and rhinitis among the younger age group, and associated with the prevalence of rhinitis among the older age group. The twospotted spider mite might be a common sensitizing allergen in the general population of adults, and sensitization to this mite may play a role in the manifestation of asthma and rhinitis symptoms during adulthood.
