The causes for airway obstruction include foreign body aspiration, congenital structural abnormalities of the airway, infection, etc. And the potential causes of acute respiratory distress contain many situations, like hyperventilation, vasodepressor syncope, asthma, etc. A major factor that leads to the exacerbation of respiratory disorders is undue stress, either physiologic or psychologic. Psychologic stress in dentistry is the primary factor in the exacerbation of preexisting medical problems. Adequate pretreatment medical and dental evaluation of the prospective patient can often prevent respiratory problems from developing. The dentist can modify patient management to minimize the risk of exacerbating these conditions. When dental anxiety is a major factor, the use of psychosedative procedures and other stress-reduction techniques should also be considered. This is the report of a children case of airway obstruction and respiratory distress owing to sedation complication by use of Chloral hydrate and Ketamine before extraction of the mesiodens in a patient with bronchial asthma and tonsillar hyperplasia. After these situations, the patient was consulted & referred to the department of Pediatrics and Otorhinolaryngology.

Purpose: To investigate the clinical characteristics of late-onset epilepsy combined with autism spectrum disorder (ASD), and the relationship between certain types of electroencephalography (EEG) abnormalities in ASD and associated neuropsychological problems. Methods: Thirty patients diagnosed with ASD in early childhood and later developed clinical seizures were reviewed retrospectively. First, the clinical characteristics, language and behavioral regression, and EEG findings of these late-onset epilepsy patients with ASD were investigated. The patients were then classified into 2 groups according to the severity of the EEG abnormalities in the background rhythm and paroxysmal discharges. In the severe group, EEG showed persistent asymmetry, slow and disorganized background rhythms, and continuous sharp and slow waves during slow sleep (CSWS). Results: Between the two groups, there was no statistically significant difference in mean age (P=0.259), age of epilepsy diagnosis (P=0.237), associated family history (P=0.074), and positive abnormal magnetic resonance image (MRI) findings (P=0.084). The severe EEG group tended to have more neuropsychological problems (P=0.074). The severe group statistically showed more electrographic seizures in EEG (P=0.000). Rett syndrome was correlated with more severe EEG abnormalities (P=0.002). Although formal cognitive function tests were not performed, the parents reported an improvement in neuropsychological function on the follow up checkup according to a parent's questionnaire. Conclusion: Although some ASD patients with late-onset epilepsy showed severe EEG abnormalities, including CSWS, they generally showed an improvement in EEG and clinical symptoms in the longterm follow up. In addition, severe EEG abnormalities tended to be related to the neuropsychological function.

The most common local cause of active gingival bleeding is the vessel engorgement and erosion by severe inflammation. Abnormal gingival bleeding is also associated with the systemic disturbances. Hemorrhagic disorders in which abnormal gingival bleeding is encountered include the following: vascular abnormalities (vitamin C deficiency or allergy), platelet disorders, hypoprothrombinemia (vitamin K deficiency resulting from liver disease), and other coagulation defects (hemophilia, leukemia). There are many conventional methods for gingival bleeding control, such as, direct pressure, electrocoagulation, direct suture, drainage, application of hemostatic agents and crushing and packing. If the active continuous gingival bleeding is not stopped in spite of the application of all conventional bleeding control methods, the life of patient is threatened owing to upper airway obstruction, syncope, vomiting and hypovolemic shock. Therefore, the rapid and correct hemostatic method is very important in the emergency dental care. This is a case report of active gingival bleeding care via dental crown removal and emergency primary endodontic drainage as a last method in liver cirrhosis patient with advanced periodontitis.

Background: A novel 2009 influenza A (H1N1) virus emerged and disseminated to all over the world. There are few reports on the clinical characteristics of patients with complications. We describe the clinical features of pneumonia in adult patients hospitalized, who have novel influenza infection. Methods: There were 43 adult patients enrolled into the study with pneumonia of 528 hospitalized patients confirmed influenza A (H1N1) virus infection by real-time reverse transcriptase polymerase chain reaction testing, between 24 August 2009 and 31 January 2010. The clinical data of patients with pneumonia were collected retrospectively. Results: There were 22 of 43 (51.2%) influenza patients with pneumonia that had higher risk factors for complications. Compared to 28 patients with influenza A (H1N1) viral pneumonia and 15 patients, who had isolated bacteria from cultures, those with mixed viral and bacterial pneumonia were significantly more likely to have unilobar consolidations on chest radiographs (53.3 vs. 10.7%, p<0.01) and higher scores of pneumonia severity index (PSI; 90 [66~100] vs. 53 [28~90], p=0.04). Six patients required mechanical ventilation support in an Intensive Care Unit and were more likely to have dyspnea (83.3 vs. 29.3%, p=0.02) and low levels of $PaO_2$ (48.3 [37.0~70.5] vs 64.0 [60.0~74.5] mm Hg, p=0.02) and high levels of pneumonia severity index (PSI) score (108.0 [74.5~142.8] vs. 56.0 [40.5~91.0], p=0.03). Conclusion: The majority of pneumonia patients infected with novel influenza improved. Chest radiographic findings of unilobar consolidations suggest that mixed pneumonia is more likely. Initial dyspnea, hypoxemia, and high levels of PSI score are associated with undergoing mechanical ventilation support.

After orthognathic surgery, postoperative complications are studied by many clinician. The complications include sensory disturbance, jaw fracture, excessive bleeding, condylar positional changes and loss of pulp vitality. Few surgical procedures are as satisfying for the surgeon and patient as a well-done orthognathic surgery. On the other hand, the patient is more satisfied with the result than who are treated with only orthodontic treatment especially in severe deformity case. There are problems that patient overcome but it is not serious complications. One of these, the problem about loss of pulp vitality can't influence function but give a lot of discomfort to the patient. From September 1997 to January 1998, 7 patients who are treated for dentofacial deformity via Le Fort I osteotomy or anterior segmental osteotomy were examined pulp sensitivity using digital pulp tester. This preliminary study have a focus on the investigation of recovery of pulp vitality. The electric pulpal test were used at preoperative, postoperative, at intervals. And we report some results acquired from this study. Follwing result are obtained 1. In anterior segmental ostetomy case (1 case), total 12 teeth were examined. Postoperative 8 weeks, 1 tooth are positive reaction 2. In Le Fort I osteotomy case (6 case), total 71 teeth were examined. Postoperative 8 weeks, 5 teeth are positive reaction
