One-hundred-eleven herpes simplex viruses(HSV) were isolated from l09 patients who had visited the Department of Dermatology, Ophthalmology, and Gynecology of Hanyang University Hospital from 1986 through 1988, for suspected HSV lesions. The cultured viruses were classified into HSV-1 and HSV-2 by using direct and indirect immunofluorescent staining with monoclonal antibodies against HSV. In this study, HSV type 1 were predominantly involved in the HSV lesions above the waist of the patients(83.6%), and the infections caused by HSV type 2(I3.1 %) and bath HSV types(3.3%) were also noted. In contrast, the main organism of the HSV lesions below the waist were HSV-2(80.0%), and HSV-1(16.0% ) and both types(4.0%) were also involved in. The result suggested that the number of patients with HSV 1 genital herpes and/or with non-genital herpes by HSV-2 were apparently increasing. In conclusion, it is conceivable that the classification of HSV isolates might be useful for determining prognosis as well as performing epidemiologic studies of HSV infections.

A choledochocele is a benign cyst-like herniation of the intramural segment of the distal common bile duct protruding into the duodenal lumen. Cholangiography is essential to demonstrate a choledochocele. Because choledochoceles are often associated with characteristic structual alterations of the papilla of Vater and the peripapillary area, ERCP is helpful in demonstrating a choledochocele. We present the clinical, endoscopic and radiographic (ERCP) findings in a patient with choledochocele.

We report two cases of malignant schwannoma of skin in association with non-familial neurofibromatosis. Case 1, a 47 year old man, had a large subcutaneous tumor on the sacral area and case 2, a 62 year old woman, a painful, ulcerating tumor on the posterior aspect of the left arm. Both cases were histopathologically confirmed as malignant schwannomas and immunohistochemical studies showed 5-100 protein in the tumor cells. After surgical excision of the tumors, case 1 was lost to follow up, while case 2 remained without evidence of disease for more than one and half years.

PURPOSE: The aim of this study was to evaluate the periodontal and prosthodontic complications of multiple freestanding implants in the posterior jaws for up to 1 year of function. MATERIAL AND METHODS: Eight patients received 20 implants posterior to canines. Two or more implants were consecutively inserted to each patient. Single crowns were delivered onto the implants. Marginal bone loss, implant mobility, probing depth, and screw loosening were examined to evaluate the clinical success of such restorations for maximum 1 year of functional loading. RESULTS: All the implants performed well during the observation period. Neither periodontal nor prosthodontic complications were found except a slight porcelain chipping. While the marginal bone level was on average 0.09 mm lower around the implant after 6 months of loading, it was 0.15 mm higher after 1 year. CONCLUSION: Within the limits of this investigation, separate single-tooth implant restorations to replace consecutive missing teeth may clinically function well in the posterior jaw.

Background: In Korea, patients with fever have been preemptively isolated to isolation beds in the emergency department (ED) since the coronavirus disease 2019 (COVID-19) pandemic began. However, isolation beds were not always available, and transport delays or failure (nontransport), especially for infants, were reported in the media. Few studies have focused on delays and failure in transporting fever patients to the ED. Therefore, this study aimed to examine and compare the emergency medical service (EMS) time interval and nontransport rate of patients with fever using EMSs before and after COVID-19. Methods: This retrospective observational study analyzed the prehospital EMS time interval and nontransport rate of fever patients who contacted EMSs in Busan, South Korea, from March 1, 2019 to February 28, 2022, using emergency dispatch reports. All fever patients (≥ 37.5°C) who contacted EMSs during this study were included. The EMS time interval was defined as the time between the patient’s EMS call and ED arrival time. Nontransport was defined as a case recorded as not being transported in the emergency dispatch reports.The study population of 2019 was compared to the population of 2020 and 2021 with the independent t-test, Mann-Whitney U test, and χ 2 test. As a subgroup, the EMS time intervals and nontransport rates of infants with fever were compared before and after COVID-19. Results: A total of 554,186 patients accessed the EMS during the study period, and 46,253 patients with fever were included. The EMS time interval (mean ± standard deviation, minutes) of fever patients was 30.9 ± 29.9 in 2019, 46.8 ± 127.8 in 2020 (P < 0.001) and 45.9 ± 34.0 in 2021 ( P < 0.001). The nontransport rate (%) was 4.4 in 2019, 20.6 in 2020 (P < 0.001), and 19.5 in 2021 (P < 0.001). For infants with fever, the EMS time interval was 27.6 ± 10.8 in 2019, 35.1 ± 15.4 in 2020 (P < 0.001), and 42.3 ± 20.5 in 2021 (P < 0.001), and the nontransport rate (%) was 2.6 in 2019, 25.0 in 2020, and 19.7 in 2021. Conclusion After the emergence of COVID-19, in Busan, the EMS time interval of fever patients was delayed, and approximately 20% of fever patients were not transported.However, infants with fever had shorter EMS time intervals and higher nontransport rates than the overall study population. A comprehensive approach, including prehospital and hospital ED flow improvements, is required beyond increasing the number of isolation beds.

The endoscopic fine needle aspiration cytology may add to the diagnostic accuracy of endoscopic biopsy and brush cytology. It is also of particular value in submucosal, infiltrative and ulceronecrotic tumors. Endoscopic fine needle aspiration cytology was done with sclerotherapy needle(23 gauge) in. the 17 patients with submucosal tumor(18 cases), extrinsic compression(2 cases), infiltrative gastric cancer(one case) and cancer of the ampulla of Vater(one case) on the upper gastrointestinal endoscopy. Endoscopic fine needle aspiration cytology established the diagnosis in 6 cases(submucosal tumor of the stomach; 2 cases, submucosal tumor of the duodenum; one case, extrinsic mass of the duodenum; one case, infiltrative cancer of the stomach; one case, and the cancer of ampulla of Vater; one case) of 17 cases. There were negative results for malignancy in 7 cases and material insufficiency in 4 cases. Five cases of the positive results with endoscopic fine needle aspiration cytology were not diagnosed with endoscopic forceps biopsies. There was no complication. We conclude that endoscopic fine needle aspiration cytology is a simple and safe technique and is of particular value in submucosal tumor, extrinsic compression of the upper gastrointestinal tract by tumor, and infiltrative gastric cancer.

Esthetics is important in restoring maxillary anterior area. Alveolar bone resorption and loss of interdental papilla may be minimized by immediate implantation. Previous studies showed successful results with the immediate implantation in healthy extraction socket, while many of these studies objected the immediate implantation into extraction sites with periapical lesions. Recent studies, however, reported successful results of the immediate implantation into extraction sites with periapical lesions with careful debridement of extraction sockets and general medication of antibiotics prior to implantation. A 73-year-old female visited the department of Prosthodontics in oo University Dental Hospital with the chief complaint of fallen post-core and crown on left maxillary incisor. Although the incisor was with vertical root fracture and periapical lesion, the immediate implantation following the extraction of tooth was planned. Thorough socket debridement, irrigation with chlorhexidine, and tetracycline soaking were followed by immediate implantation. The general medication of antibiotics (Moxicle Tab.(R), 375 mg) was prescribed before and after the surgery. Immediate provisional restoration was delivered two days after the surgery, and the definitive metal-ceramic restoration was placed about six months later after reproducing the emergence profile from the provisional restoration. This case presents satisfying result esthetically and functionally upto two years after the placement of prosthesis with the harmonious gingival line and no loss of marginal bone.

BACKGROUND: It is not clear whether mild hypothermia (34 degrees C) enhances stress hormonal responses during surgery under general intravenous anesthesia. The purpose of this study was determine how mild hypothermia affects hemodymic and stress hormonal responses introperatively and during extubation in patients undergoing cerebral aneurysm surgery under general intravenous anesthesia. METHODS: Anesthesia was induced intravenously with thiopental sodium 5 mg/kg, succinylcholine 1 mg/kg, and maintained with 50% O2, 50% N2O, and propofol using a target controlled system; Diprifusor(R) (3-5 microgram/ml) and muscle relaxation were administered with intravenous vecuronium intermittently. For the normothermia and the hypothermia groups, body temperatures were maintained at 36.9+/-0.3degrees C and 34.2+/-0.2 degrees C, respectively, up to the recovery room. Hemodynamic changes were recorded continuously. Arterial blood gas analysis, glucose, hemoglobin, stress hormones comprising epinephrine, norepinephrine, ADH, ACTH and cortisol were measured at whilst awake, intraoperatively, and just after extubation. RESULTS: Hemodynamic changes from the awake control state to postextubation were not significantly different between the normothermia and hypothermia groups. In the control awake state, all five hormonal concentrations were similar in the two groups. Intraoperatively and during extubation, all hormonal concentrations tended to be lower in the hypothermia group than in the normothermia group, except epinephrine during extubation. During the same period, all except ACTH decreased sufficiently to reach statistical significance (P < 0.05) versus the awake control state. But no significant differents were found between the two groups. CONCLUSIONS: Our data suggest that intraoperative mild hypothermia dose not significantly affect hemodynamic changes or the plasma concentrations of stress hormones.
