Epiglottis abnormality is rare condition and can lead embarrassing intubation to anesthesiologists. Here, we reported a case of successful management in a patient with unexpected hidden vocal cords due to epiglottis adhesion to the posterior wall of the laryngeal cavity. Case: A 60-year-old female with no underlying disease was scheduled for general anesthesia to undergo a left-cochlear implant operation. After the induction procedure (including intravenous injection of rocuronium), an epiglottic adhesion to the posterior wall of the laryngeal cavity and invisible vocal cords were confirmed. Although the first trial of intubation failed, the patient’s airway was successfully managed using a technique that combined a video-styletscope (Markstein Sichtec Medical Co., 5.0 mm ID) with a video-laryngoscope (Insighters ®, Cedrus Medical). Conclusions: Anesthesiologists may unexpectedly encounter asymptomatic abnormal airways with unknown causes. In such a situation, it is essential to establish a strategy and to select appropriate device according to patient circumstances.

BACKGROUND: Respiratory viral infections can become epidemic due to high contagiosity. Since there was no rapid diagnostic method for complete diagnosis in the past, diagnosis was solely made on the basis of clinical symptoms or the time of infection. With recent developments in rapid diagnostic methods like multiplex reverse transcriptase (RT)-PCR, R-mix virus culture, etc., early detection and effective treatment of respiratory viral infections is possible. Herein, we compared the efficiency of multiplex RT-PCR and the R-mix virus culture for the rapid detection of respiratory viruses. METHODS: We used 96 nasopharyngeal swab specimens for culturing respiratory viruses using R-mix (Diagnostics Hybrids Inc., USA). Afterwards, multiplex RT-PCR was performed using specimens stored at -70degrees C. RESULTS: R-mix virus culture yielded positive results in 34 cases (35.4%) and multiplex RT-PCR in 73 cases (76.0%). Both methods yielded identical results in 51 cases (29 positive cases and 22 negative cases). Among 45 cases that showed different results, 40 showed negative results in R-mix virus culture and positive results in multiplex RT-PCR, and 1 showed positive result in R-mix virus culture and negative result in multiplex RT-PCR. Different viruses were detected in the remaining 4 cases by both the methods. CONCLUSIONS: Multiplex RT-PCR provided faster results and had higher detection rates than R-mix virus culture. Further, unlike R-mix virus culture, multiplex RT-PCR can be used to identify new respiratory viruses. Therefore, multiplex RT-PCR is more useful than R-mix virus culture in the diagnosis of respiratory virus infection.

OBJECTIVE: Tributyltin (TBT), an endocrine disrupting chemical, has been reported to decrease ovarian function by causing apoptosis in the ovary, but the mechanism is not fully understood. Therefore, we examined whether TBT increases the expression of adipogenesis-related genes in the ovary and the increased expression of these genes is associated with apoptosis induction. METHODS: Three-week-old Sprague-Dawley rats were orally administered TBT (1 or 10 mg/kg body weight) or sesame oil as a control for 7 days. The ovaries were obtained and weighed on day 8, and then they were fixed for terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) or frozen for RNA extraction. Using the total RNA of the ovaries, adipogenesis- and apoptosis-related genes were analyzed by real-time polymerase chain reaction (PCR). RESULTS: The ovarian weight was significantly decreased in rats administered 10 mg/kg TBT compared to that in control rats. As determined by the TUNEL assay, the number of apoptotic follicles in ovary was significantly increased in rats administered 10 mg/kg TBT. The real-time PCR results showed that the expression of adipogenesis-related genes such as PPARgamma, aP2, CD36, and PEPCK was increased after TBT administration. In addition, apoptosis-related genes such as TNFalpha and TNFR1 were expressed more in the TBT-administered rats compared with the control rats. CONCLUSION: The present study demonstrates that TBT induces the expression of adipogenesis- and apoptosis-related genes in the ovary leading to apoptosis in the ovarian follicles. These results suggest that the increased expression of adipogenesis-related genes in the ovary by TBT exposure might induce apoptosis resulting in a loss of ovarian function.

OBJECTIVE: To examine the relation between the presence of penetration or aspiration and the occurrence of the clinical indicators of dysphagia. The presence of penetration or aspiration is closely related to the clinical indicators of dysphagia. It is essential to understand these relationships in order to implement proper diagnosis and treatment of dysphagia. METHODS: Fifty-eight poststroke survivors were divided into two groups: patients with or without penetration or aspiration. Medical records and videofluoroscopic swallowing examinations were reviewed. The occurrence of clinical indicators of dysphagia between two groups was analyzed with Cross Tabulation and the Pearson chi-square test (p<0.05). RESULTS: Poststroke survivors with penetration or aspiration had significantly high occurrences of delayed initiation of the swallow (p=0.04) and reduced hyolaryngeal elevation (p<0.01) than those without penetration or aspiration. CONCLUSION: The results of this study indicate that delayed initiation of the swallow is a strong physiological indicator of penetration or aspiration during the oral stage of swallowing in poststroke survivors. For the pharyngeal stage of swallowing, hyoid and laryngeal elevation is a key event related to occurrence of penetration or aspiration. Clinical indicators should be investigated further to allow appropriate implementation of treatment strategies for stroke survivors.

OBJECTIVES: Problem behaviors pose a great obstacle to daily functioning in children with neurodevelopmental deficits and are an important target for treatment. In this study, we translated the Behavior Problems Inventory (BPI)-01 into Korean language and tested its psychometric properties. METHODS: We attained the approval of the BPI author and performed standard translation-back translation. Then, professional caregivers examined appropriateness according to cultural and situational contexts in order to make necessary modifications of the Korean version of the BPI. RESULTS: The BPI-01, Korea-Scales of Independent Behavior-Revised (K-SIB-R), and Child Behavior Checklist were completed for 98 autistic spectrum disorder or intellectual development disorder participants (mean age=28.3, standard deviation=7.3, range=10.1–51.7). The inter-rater reliability of the BPI-01 was found to be high (r=0.992–1.000). As for the results for concurrent validity for subscale items of BPI-01 and scales of SIB, correlations between SIB and BPI-01 subscales were statistically significant (r=0.357–0.672). CONCLUSION: The Korean version of the BPI-01 showed good psychometric properties with high reliability and sufficient convergent validity. Further examination of the validity of BPI-01 should be carried out with inclusion of younger aged children and a closer look at less frequently occurring symptoms.
