Isolated sphenoid sinusitis is a rare disorder. There are some difficulties in its diagnosis; therefore the first presentation of this disorder might be with complications. These complications are essentially due to the anatomical location of the sinus and its proximity to the intra-cranial and orbital contents, to which infection may easily spread. A case of isolated sphenoid fungal sinusitis with unilateral abducent nerve palsy is being reported which was successfully treated by parenteral antibiotic therapy and endonasal endoscopic sphenoidotomy.

An epiglottic cyst is a common form of laryngeal cysts which are rare causes of upper airway obstruction. A congenital laryngeal cyst always causes neonatal respiratory distress, but an acquired cyst shows very wide spectrum of symptoms such as no specific complaints, dysphagia, respiratory difficulty, or even death according to its size, location, or age. From anesthesiologists' point of view, an asymptomatic undiagnosed laryngeal cyst is a major concern. Unexpectedly, it can cause difficult airway such as 'cannnot intubate' or 'cannot intubate and cannot ventilate' situation during anesthesia. Recently we discovered an undiagnosed epiglottic cyst obscuring laryngeal inlet, leading to difficult intubation during general anesthesia for decompression and fusion of lumbar vertebrae. Fortunately, mask ventilation was possible, and after failed attempts of direct laryngoscopy, we could perform oral fiberoptic bronchoscope-aided intubation. He was discharged 10 days later with no harmful events.

PURPOSE: Natural orifice transluminal endoscopic surgery (NOTES) is a new method of accessing intracavitary organs in order to minimize pain by avoiding incisions in the body wall. The aim of this study is to determine patients' acceptance of NOTES in Korea and to compare their views about laparoscopic surgery and NOTES for benign and malignant diseases. MATERIALS AND METHODS: The target number of total subjects was calculated to be 540. The subjects were classified into 18 sub-groups based on age groups, gender, and history of prior surgery. The questionnaire elicited information about demographic characteristics, medical check-ups, diseases, endoscopic and surgical histories, marital status and childbirth, the acceptance of NOTES, and the preferred routes for NOTES. In addition, the subjects chose laparoscopic surgery or NOTES for a hypothetical cholecystectomy and rectal cancer surgery, and responded to questions regarding the acceptable complication rate of NOTES, the appropriate cost of NOTES, and the reason(s) why they did not select NOTES. RESULTS: 486 of 540 patients (90.0%) who agreed to participate in this study completed the questionnaire. NOTES was preferred by the following patients: elderly; a history of treatment due to a disease; having regular check-ups; and a history of an endoscopic procedure (p<0.05). The most preferred route for NOTES was the stomach (67.1%). Eighty-four percent of the patients choosing NOTES responded that the complication rate of the new surgical method should be the same or lower than laparoscopic surgery. Vague anxiety over a new surgical method was the most common reason why NOTES was not selected in benign and malignant diseases (64% and 73%), respectively. CONCLUSION: Patients appear to be interested in the potential benefits of NOTES and would embrace it if their concerns about safety are met. We believe that qualified surgical endoscopists can meet these safety concerns, and that NOTES development has the potential to flourish.

OBJECTIVE: It was to analyze two failed arterial embolization cases in the treatment for pseudoaneurysm followed by D&C. METHODS: Two failure cases out of eight cases were gained in the transarterial embolization treatment for eight years.(1. 1. 1992 - 12. 31. 1999) To search for the factors of failure, we went through obstetrical history and biopsy. RESULTS: Eight cases of transarterial embolization were performed to the treatment for pseudoaneurysm appeared after undergoing D&C. Six cases were successfully treated without complications. However, laparotomy was done due to the continuous bleeding in the other two cases. According to tissue biopsy, they showed the cervical pregnancy in one case and placenta accreta in the other. CONCLUSION: Transarterial embolization is proved to be more preferable to operate in the treatment of pseudoaneurysm than laparotomy, and transarterial embolization therapy failure rate is higher in case of existing remnant villi than not.

Percutaneous catheter-based therapy has recently been introduced to decrease blood pressure by ablation of efferent and afferent sympathetic renal nerves. The patient described here had a seven-year history of hypertension and presented with poorly controlled blood pressure despite antihypertensive therapy with four different drugs. A 44-yr-old man underwent percutaneous renal denervation under local anesthesia using an ablation catheter. After six months of follow-up his blood pressure had dropped 49/37 mmHg with a decrease in 24-hr ambulatory BP of 20/18 mmHg. Renal Doppler ultrasound showed no significant stenosis in either renal artery. This is the first case of successful percutaneous renal denervation, which has recently become available in Korea.

Stent migration from the delivery balloon catheter is a rare but serious complication during percutaneous coronary intervention, particularly when a part of the stent stretches into the aorta. We report an unusual case of stent migration treated with a combination of a gooseneck snare and rotablation. A part of the stent was overstretched and unrolled into the aorta and the rest of the stent remained implanted in the coronary artery. The stent was captured with a gooseneck snare but could not be retrieved because it was connected to a stent remnant implanted in the coronary artery. The stent strut was cut with rotablation, and the stent was successfully removed through the femoral sheath.

BACKGROUND: The telemedicine services in Korea are expected to rapidly expand its use to the general population due to the development of digital networking, and its recent revision of related law and regulations. The purpose of this study was to investigate the knowledge and attitude of telemedicine in primary care patients. METHODS: We enrolled a total 243 participants, visited Family Medicine clinics and health promotion centers of university hospital in Seoul metrocity and Chungju city from April 1, 2010 to May 31, 2010. Data was collected by questionnaire, including demographic variables, knowledge and attitude of telemedicine. RESULTS: Among the total of 243 participants, 117 (49.8%) respondents were aware of telemedicine, and 178 (73.3%) respondents preferred telemedicine. The awareness showed differences according to the residence (P = 0.007), education (P = 0.03), and occupation (P = 0.02) of the respondents. The patient preference showed the differences at 50 years of age (P = 0.01) and in income of the participants (P = 0.005). CONCLUSION: Awareness of telemedicine in primary care patients was low. As for the patients more than 50 years of age who will be having difficulty manipulating the instruments, more education is crucial. Establishment of appropriate plans to increase patient preference is needed, especially for patients with low-incomes.

BACKGROUND: Ventilation is a major determinant of the alveolar concentration of inhaled anesthetics. Hyperventilation accelerates the equilibration of anesthetic in the lungs, but decelerates it in the brain. We evaluated this phenomenon for desflurane. METHODS: Twenty healthy subjects were enrolled after IRB approval. End-tidal concentrations of desflurane (P.DESF) were recorded during 10 minutes of mask induction with 8% desflurane. P.DESF was modeled with time and end-tidal concentrations of CO2 (P.ETCO2) using a two-exponential pharmacokinetic equation. Bispectral index (BIS) values were also measured to find out the component reflecting the cerebral concentration of desflurane. RESULTS: During induction, the rise of P.DESF could be separated into two components: early and late rises. Individual BIS values showed a higher correlation with the late component of P.DESF (P = 0.000). P.ETCO2 had two different effects on the rise of P.DESF. CONCLUSIONS: Hyperventilation hastened the early rise and delayed the late rise of P.DESF (P = 0.00, P = 0.00). Hyperventilation should be avoided to obtain rapid anesthesia induction with desflurane.

The aim of this study was to develop a nonlinear mixed-effects model for the increase in cerebral oximetry (rSO2) during the rapid introduction of desflurane, and to determine the effect of hypocapnia and N2O on the model. Twelve American Society of Anesthesiologist physical status class 1 and 2 subjects were allocated randomly into an Air and N2O group. After inducing anesthesia, desflurane was then increased abruptly from 4.0 to 12.0%. The PET(CO2), PET(DESF) and rSO2 were recorded at 12 predetermined periods for the following 10 min. The maximum increase in rSO2 reached +24-25% during normocapnia. The increase in rSO2 could be fitted to a four parameter logistic equation as a function of the logarithm of PET(DESF). Hypocapnia reduced the maximum response of rSO2, shifted the EC50 to the right, and increased the slope in the Air group. N2O shifted the EC50 to the right, and reduced the slope leaving the maximum rSO2 unchanged. The N2O-effects disappeared during hypocapnia. The cerebrovascular reactivity of rSO2 to CO2 is still preserved during the rapid introduction of desflurane. N2O slows the response of rSO2. Hypocapnia overwhelms all the effects of N2O.

Hysteroscopic surgery has become a routine gynecologic procedure. The advantages are associated with more accurate removal of lesion, its short operating time, rapid post-operative recovery and low morbidity. However, there are potentially serious complications which can be occured during and following hysteroscopic surgery. The complications are uterine perforation, fluid overload and electrolyte disturbance due to intravasation and absorption of uterine distention media, hemorrhage and, rarely, gas or air embolism. We experienced pulmonary edema during hysteroscopic surgery in three consecutive patients. Therefore, we report these cases of fluid overload with uterine distention media resulting acute pulmonary edema during hysteroscopic surgery.
