Anxiety and fear is two main factors that keep patients from going to dental clinic. Especially, patients may feel implants operations are more traumatic. Intravenous conscious sedation for dental treatment can make patient comfortable and relaxable. Midazolam is more popular for sedation for dental treatment, but target-controlled infusion (TCI) of propofol and remifentanil is gaining wide popularity. A 54-year-old female patient who had severe dental phobia was referred to our dental hospital. She had past history of 2 times of hyperventilation and syncope during dental treatment. The patient showed a lot of dental anxiety and fear to dental treatments and stress reduction protocol was needed. We administered intravenous conscious sedation using target controlled infusion system with remifentanil and propofol. During sedation, we monitored the status of consciousness with bispectral index and vital signs. Dental treatment could be finished successfully without any problems.

관상동맥질환의 진단 및 평가에 있어서 myocardial perfusion SPECT검사와 FDG를 이용한 myocardial PET검사 그리고 PET/CT에 장착된 64-slice CT를 이용한 coronary CT angiography를 동시에 실행함으로 검사의 신뢰도와 편의성을 한층 더 높이고자 한다. 먼저 약물부하 myocardial perfusion SPECT검사를 먼저 시행한다. 환자의 피폭경감을 위해서 $^{99m}Tc$-MIBI 10 mCi 로 주사하며 myocardial PET검사를 위해서 지방식을 먹지 않고 ursodeoxcholic acid 100 mg을 생수와 함께 복용하게 하여 1시간 후에 SPECT 영상을 얻는다. 이어서 myocardial FDG PET검사를 시행한다. 혈중의 지방산 농도를 낮추고 심장의 FDG섭취율을 증가시키기 위해 혈중 포도당 농도치에 따라 insulin과 Acipimox를 함께 사용하는 독창적인 경구 당 부하법을 사용하였으며, 환자의 피폭 경감을 위해서 $^{18}F$-FDG 5 mCi를 주사하고 1시간 후에 10분간 gated 영상을 얻으며 필요시 delay 영상을 얻는다. PET검사가 끝남과 동시에 환자는 동일한 position을 하고 연속해서 coronary CTA를 시행한다. 이 검사에서 가장 중요한 것은 심박동수 조절과 환자의 호흡협조이다. 심박동수를 65회 이하로 낮추기 위해 beta blocker 50 mg~200 mg을 의사와 상의하여 복용케 하고 호흡법을 충분히 연습을 시키다. 검사 직전에 isosorbide dinitrate를 3~5회 분무하여 혈관벽의 긴장을 낮추고 혈관을 확장시켜서 coronary artery의 해부학적 형태를 더욱 잘 나타낼 수 있게 한다. 촬영 시 CT 조영제를 4.0~5.0 mL/sec의 압력으로 주입하며 촬영을 한다. Coronary CTA를 이용하면 coronary artery stenosis가 잘 보이며, 약물부하 myocardial perfusion SPECT로 coronary CTA에서 보인 stenosis와 perfusion저하의 상관관계를 검토(culprit vessel 확인)할 수 있으며, FDG PET으로 hibernating myocardium 또는 infarction site의 viability를 확인할 수 있다. 한 가지 검사로 lesion site와 severity 및 치료에 대한 반응 예측이 가능함으로 약물치료, PCI, CABG 등 치료방향을 설정할 수 있다. 또한 모든 검사 과정들이 연속적으로 동시에 이루어지기 때문에 짧은 시간(3시간) 내에 one-stop으로 검사를 종료할 수 있는 큰 장점을 가지게 된다. 그러므로 이 검사법은 ischemic heart disease의 one-stop evaluation에 있어서 유용한 protocol로 보여진다.

Extension of advanced odontogenic infection from deep neck fascial spaces into the mediastinum is heralded by chest pain, dyspnea, fever, and radiographic demonstration of mediastinal widening. The critical care should be done in a team approach by multiple medical and dental departments, such as, oral & maxillofacial surgery, otolaryngology, anesthesiology, chest surgery, and infection medicine. Especially, fluid & drug therapy, adequate incision & drainage and systemic supportive psychosedation care are important. But, acute hyperventilation can be produced by several distinct causes: severe anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The orofacial fears about acute pain, trismus, dysphagia, swelling and oral surgical treatment lead to the severe anxiety and increased blood catecholamine level by stress. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the care, hyperventilation was occurred during psychosedation and local anesthesia for incision and drainage of the masticatory fascial space abscess with deep neck infection & mediastinitis. We suggest that the dental patient with advanced odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.

Purpose: This study was based on the Korean Foot and Ankle Society (KFAS) member survey and aimed to report the current trends in the management of syndesmotic injuries over the last few decades. Materials and Methods: A web-based questionnaire containing 36 questions was sent to all KFAS members in September 2021. The questions were mainly related to the preferred techniques and clinical experiences in the treatment of patients with syndesmotic injuries. Answers with a prevalence ≥50% of respondents were considered a tendency. Results: Seventy-six (13.8%) of the 550 members responded to the survey. The results showed that the most preferred method to diagnose a syndesmotic injury was magnetic resonance imaging (MRI). Intraoperatively, the external rotation stress test and the Cotton test were most frequently used to confirm syndesmotic diastasis. The reduction was usually done by a reduction clamp. One 3.5-mm screw was used most frequently over three cortices at 2~4 cm above the ankle joint. The preferred ankle position during fixation was 0° dorsiflexion. Removal of the syndesmotic screw was routinely done by most surgeons, mainly because of the limitation of movement and risk of screw breakage. Factors that affect suture button selection included non-rigid fixation which enables adequate fixation, early weight-bearing, and an infrequent need to remove the hardware. Inadequate reduction was considered the main factor that affects poor prognosis. Conclusion: This study proposes updated information about the current trends in the management of syndesmotic injuries in Korea. Consensuses in both the diagnostic and therapeutic approach to patients with syndesmotic injury were identified in this survey study. This study may raise the awareness of the various possible approaches toward the injury and should be used to further establish a standard protocol for the management of syndesmotic injuries.

This is a reprospective study on the care of odontogenic infections in admission patients with geriatric diseases. The study was based on a series of 480 patients at Dong San Medical Center, Wonju Christian Hospital and Il San Health Insurance Hospital, From Jan. 1, 2000, to Dec. 31, 2002. The Obtained results were as follows: 1. The systemic malignant tumor was the most frequent cause of the geriatric diseases with odontogenic infectious diseases, and refractory lung disease, systemic heart disease, type II diabetes mellitus, cerebrovascular disease, bone & joint disease, senile psychologic disease were next in order of frequency. 2. Male prediction(57.5%) was existed in the odontogenic infectious patients with geriatric diseases. But, there were female prediction in senile psychologic disease, systemic heart disease and cerebrovascular disease. 3. The most common age group of the odontogenic infectious patient with geriatric disease was the sixty decade(47.9%), followed by the seventy & eighty decade in order. 4. In the contents of chief complaints on the odontogenic infectious patients with geriatric disease, peak incidence was occurred as toothache(52.7%), followed by extraction wish, tooth mobility, oral bleeding, oral ulcer, fracture of restoration, gingival swelling in order. 5. In the diagnosis group of odontogenic infectious diseases, periodontitis, pulpitis & periapical abscess were more common. 6. In the treatment group of odontogenic infectious diseases, the most frequent incidence(34.2%) was showed in primary endodontic treatment (pulp extirpation, occlusal reduction and canal opening drainage) and followed by scaling, incision & drainage, only drugs, pulp capping, restoration in order.
