The majority of flexible bronchoscopies are performed under topical anesthesia with lidocaine being the most commonly used agent. Anaphylaxis rarely occurs after local administration of lidocaine, but can be a fatal complication. We experienced a case of unexpected anaphylaxis. A 66-year-old woman was scheduled for flexible bronchoscopy to evaluate a tracheal mass and stenosis. The oral and nasal mucosa were pretreated with lidocaine. About 2~3 minutes later, the patient developed hypotension and we treated for anaphylaxis in the emergency room. Then, we decided to perform rigid bronchoscopy in this patient, under conditions of general anesthesia. A rigid bronchoscopy was performed in this patient, safely and successfully. The tracheal mass was determined to be squamous cell carcinoma.

Allergic rhinitis is an inflammation of the nasal mucosa which is triggered by an allergic reaction. When exposed to certain allergens, the IgE covered mast cells degranulate releasing inflammatory mediators and cytokines which results in a local inflammatory reaction. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of allergic rhinitis. This experimental study was done to research effects of Sochungryong-tang. We have studied effect of mice on OVA-induced production of IL-4, IL-5, IFN-${\gamma}$ by murine splenocytes and effect of OVA-induced total IgE and OVA-specific IgE. The results were as follows; 1. In IL-4 study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.005). 2. In IL-5 study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.05). 3. In JFN-${\gamma}$ study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 4. In Total IgE, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 5. In OVA-specific IgE, Sochungryong-tang treated group didn't showed significant inhibitory effect. Depending upon above results, it is considered that Sochungryong-tang has the inhibitory effect on the allergic rhinitis of mice and suggested that it could be used in relieving patients of the symptoms which are caused by allergic rhinitis.

After analysis according to age, sex, site of origin, nodal involvement, perineural invasion. histopathology and treatment modality. authors had reached the following conclusion about the 28 cases of adenoid cystic carcinoma of the salivary gland, which were, histopathologically, diagnosed at Yonsei University Severance Hospital and Yongdong, Severance Hospital during the 8-year period from Apr. 1983 to Mar. 1991. Among the 28 cases, 13 were females and 15 were males, which implies that there isn't any sigificant distinction of gender. The age range was 24 years to 69 years with a mean age of 49 years, and the most common site of origin in order was 6 cases(21.4%) of maxillary sinus, 5 cases(17.8%) of submandibular gland, each 4 cases(14.4%) of parotid gland, palate, 3 cases(10.4%) of nasal cavity and each 2 cases(7.1%) of mouth floor, nasopharynx with each one case(3.6%) of buccal mucosa and retromolar trigone. With clinical staging by UICC, the 5-year survival of adenoid cystic carcinoma was 100% in stage I and II, 87.5% in stage III. In stage IV, all of the patient were died within 3 years. We have known that the prognosis was poorer in following cases; the cases with higher clinical stage, primary site other than the major salivary gland especially maxillary sinus and positive neural or nodal invasion.

The present study was made with the aim of finding out the Kamihaepyoijin-tang's effect on the allergic asthma using the Egg-White Implant(EWI) method model recommended by de Siqueira et al. Kamihaepyoijin-tang has widely been prescribed and used in Oriental Medicine for controlling and curing of cough, asthma, nasal obstruction. Previous studies have demonstrated that Kamihaepyoijin-tang had analgesic, anticonvulsive effects. But it is uncertain whether Kamihaepyoijin-tang could inhibit the allergic reaction of rats with experimentally induced allergic asthma using EWI method. With such aim. the respiratory patterns and eosinophil infiltration in the tracheal mucosa of the rats were mainly observed. The results were summerized as follows ; 1. The frequency of malformed respiratory patterns in Kamihaepyoijin-tang treated groups were decreased as compared with the control group. 2. The Ratio of malformed respiratory patterns in Kamihaepyoijin-tang treated groups were significantly decreased as compared with the control group(p<0.02). 3. The eosinophil infiltration in Kamihaepyoijin-tang treated groups were decreased as compared with the control group. 4. The eosinophil infiltration that inside of trachea tissue in Kamihaepyoijin-tang treated groups were significantly decreased as compared with the control group(p<0.05). Depending upon above results, it is considered that Kamihaepyoijin-tang has the inhibitory effects on the allergic asthma of rats and suggested that it could be used in relieving patients of the symptoms which are caused by allergic asthma.

The present study was designed to investigate whether there is a consistint changes in the signals from the central and autonomic nervous systim due to olfactory stimulation. The olfactory stimuli were 0.6% orange and 2.5% valeric acid and the stimuli through the olfactory stimulator soth controlled consistint flow, controlled concentration, and saturated with vapour to prevent drying the nasal mucosa. A room air blunk served as the control stimulus, EEG was recorede from 4channels according to the international 10-20 systim. Additionally, ECG, EOG, heart rate, skin conductance and resputation were recorded comtinuously. The fast Fourier transform analysis of EEG waves was analysed with the power spectra. Averaged power spectra were computed for the following frequency bands ; delta(0-4.5Hz), theta (4.5-7Hz), alphal(7-9.5Hz), alpha2 (9.5-12.5Hz) and beta(12.5-30Hz). Withthe results of the subjective sensibility test for the ordor, the orange was related to pleasant and familiar and the valeric acid was realted to snpleasant and bothersome. There is the difference between orange and valeric acid in alphal at PG2-A2 channel. While the unpleasant stimuli seem to be increased in alphal, alpha2 and beta waves at all channels. Also, the heart rate, galvaric skin resistance seem to be decreased by pleasant stimuli and thd unpleasant stimuli shdwed the opposite. In respiration, respiration rate had been declinig tendency, and input/output ampoitued and duration showed an upward trend by olfactory stimulation with orange, while opposite by valeric acid. In conclusion, the consistent EEG changes and the autonomic responses suggests the possibilities of the subjective signal of human sensibility.

Background: Conservative treatment is performed for isolated anterior wall of the maxillary sinus fractures, in many cases when the fracture is clinically not severe and asymptomatic. Despite the absence of symptoms, complications such as sinusitis, rhinitis, and chronic purulent secretion may develop; therefore, successful reduction is required. We attempted to reduce the risk of complications using an alternative technique: reduction of the fracture with two urinary balloon catheters inserted through the maxillary ostium and fixation using fibrin glue, which minimizes the damage to the bony fragments and sinus mucosa. Methods: In this study, 38 patients who were diagnosed with an isolated anterior wall of the maxillary sinus fracture at our hospital between January 2014 and January 2017 were enrolled. The fracture site was exposed via the Caldwell-Luc approach followed by reduction through the insertion of two urinary balloon catheters using a nasal endoscope and fixation with fibrin glue. The sex, cause of fracture, physical examination, and presence of complications were examined and patient's medical records and facial bone computed tomography scans were analyzed. Results: Radiological evaluation showed that there was no evidence of collapsed reduction fragments. Although some patients had remaining symptoms of hypoesthesia (15%; 3 patients), there were no complications such as infection, rhinitis, sinusitis, and chronic purulent secretion at the surgical site. Conclusion: In this study, we present an alternative surgical technique using two urinary balloon catheters and fibrin glue for the successful reconstruction of an isolated anterior wall of the maxillary sinus fracture. This technique enables precise restoration with a reduced risk of complications.

This study was conducted to elucidate the distribution of Aujeszky's disease viral nucleic acids and antigens in the central nervous system (CNS) of piglets. The first Korean isolate of Aujeszky's disease virus(ADV) that isolated from naturally infected piglets in Yang San, was inoculated into 32 day old piglets with $10^{5.9}TCID_{50}/ml$ through intranasal or intramuscular route. These piglets were sacrificed at every 24hrs for 8 days. The immunohistochemistry (IHC) was conducted to detect the viral antigens in paraffin-embedded tissue sections using avidin-biotin-peroxidase complex (ABC) method. The viral nucleic acids were detected by in situ hybridization (ISH) using ADV specific DNA probe labeled with digoxigenin. The ADV antigens were detected in reticuloendothelial cells of spleen, lymph nodes and tonsil, alveolar walls, leptomeningeal vascular walls, inflammatory foci of each organ, and nerve cells. The viral nucleic acids were detected in the spinal trigeminal nucleus and its tracts of the pons and medulla oblongata by the ISH technique. The pathways of AD viruses in CNS were determined by IHC and ISH. In the intranasally inoculated group, the viruses in nasal mucosa moved to medulla oblongata and pons through the trigeminal nerve. In case of intramuscullarly inoculated group, viruses moved to brain via lymphoid organs or spinal nerves from sciatic nerves.

Objective: The aim of this systematic review was to evaluate the complications and side effects associated with the clinical use of orthodontic miniscrews by systematically reviewing the best available evidence. Methods: A survey of articles published up to March 2020 investigating the complications associated with miniscrew insertion, in both the maxilla and mandible, was performed using 7 electronic databases. Clinical studies, case reports, and case series reporting complications associated with the use of orthodontic miniscrew implants were included. Two authors independently performed study selection, data extraction, and risk-of-bias assessment. Results: The database survey yielded 24 articles. The risk-of-bias assessment revealed low methodological quality for the included studies. The most frequent adverse event reported was root injury with an associated periradicular lesion, vitality loss, pink discoloration of the tooth, and transitory loss of pulp sensitivity. Chronic inflammation of the soft tissue surrounding the miniscrew with mucosal overgrowth was also reported. The other adverse events reported were lesion of the buccal mucosa at the insertion site, soft-tissue necrosis, and perforation of the floor of the nasal cavity and maxillary sinus. Adverse events were also reported after miniscrew removal and included secondary bleeding, miniscrew fracture, scars, and exostosis. Conclusions: These findings highlight the need for clinicians to preliminarily assess generic and specific insertion site complications and side effects.
