OBJECTIVE: Peripartum emergency cesarean hysterectomy of 28 cases at our hospital for 10years were reviewed that the clinical indication, history, and annual incidence change. METHODS: A retrospective descriptive analysis from January, 1988 to December, 1997 was carried out. RESULTS: There were 28 cases of emergency cesarean hysterectomy identified during this period among total 24, 689 deliveries. The annual incidence of emergency cesarean hysterectomy was significantly declined statistically(p<0.005). Cesarean hysterectomy was performed in 20 of 6, 671 cesarean section(0.30%) and in 8 of 18, 018 vaginal deliveries(0.04%), so more frequently after cesarean section than vaginal delivery. The cesarean hysterectomy rate was more frequent in multiparous women(0, 22%) than in nulliparous women(0, 02%). The most common indication of cesarean hysterectomy was 13 cases of uterine atony(46%), followed by 5 cases uterine rupture(18%), 5 cases of placenta previa with placenta accreta(18%), 3 cases of placenta previa(11%), 2 cases of uterine myoma(7%). No significant difference in length of operating time, amount of blood loss and operative complications were found between total abdominal hysterectomy and subtotal hysterectomy. The all patient who had cesarean hysterectomy recieved from 1200ml to 15840ml of blood transfusion with a mean of 3673ml. In aspect of fetal outcome, 3 cases of FDIU(Fetal death in utero) in uterine rupture and 1 case of stillbirth in preterm were found. The maternal complications were wound disruption, DIC, wound hematoma, ureter injury, vaginal stump bleeding, UTI(Urinary tract infection) and retroperitoneal bleeding, CONCLUSION: We conclude that the incidence of emergency cesarean hysterectomy declined with prediction of antenatal risk factor, preparing of sufficient fresh blood, prophylactic antibiotics, vigorous uterotonics and close observation after delivery.

PURPOSE: The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. MATERIALS AND METHODS: The metal master cast was fabricated with three internal connection type implant analogs (Osstem GS III analog), embedded parallel and with 10degrees of mesial angulation to the center analog. Four types of impression coping were prepared with different combinations of types (transfer, pick-up) and lengths (long, short) of the coping. The impressions were made using vinyl polysiloxane (one step, heavy + light body) with an individual tray, and 10 impressions were made for each group. Eventually, 40 experimental casts were produced. Then, the difference in the distance between the master cast and the experimental cast were measured, and the error rate was determined. The analysis of variance was performed using the SPSS (v 12.0) program (alpha = .05), and the statistical significance was set at P < .05. RESULTS: The ANOVA showed that the pick-up type impression coping exhibited a significantly lower error rate than the transfer type. However, no significant difference was observed with respect to the length of the impression coping. Additionally, no significant difference was observed between the parallel and mesial angulated groups. CONCLUSION: Within the limitations of this study, the pick-up type impression coping exhibited a more accurate implant master cast than the transfer type in parallel group. The accuracy of the implant master cast did not differ for different lengths of impression coping of at least 11 mm. Additionally, the accuracy of the implant cast was not different for the parallel and 10degrees mesial angulated groups.

Oseltamivir has been used as a worldwide preparation for treatment of influenza A and B including H1N1. Gastrointestinal discomforts as like nausea, vomiting are commonly reported but acute hemorrhagic colitis is a very rare adverse effect. We report a case of a 17-year-old male who showed abdominal pain, diarrhea and hematochezia after the second administration of oseltamivir. Computed tomography revealed continuous, circumferential and edematous wall thickening involving ascending to descending colon with pericolic infiltration. Colonoscopic examination revealed diffuse mucosal edema, congestion and friability, suggesting hemorrhagic colitis. Histopathological examination showed ischemia and focal loss of the crypts. It also showed hyalinization and minimal inflammatory cell infiltration in the lamina propria, consistent with acute to subacute ischemic colitis. This report is the first case of oseltamivir-related ischemic colitis proved by both endoscopic examination and pathologic findings in the patient who had no risk factor of ischemic colitis in Korea.

During the three years from March, 1983 to Feb, 1986, 159 cases of head injury surgically treated in the department of neurosurgery, Capital Armed Forces General Hospital were clinicostatistically analysed and discussed with the review of the literature. The following results were obtained.1) Due to the army distinctiveness, all cases were male and the age incidence was becoming maximal at the third decade. 2) Traffic accidents form by far the largest Group(38.4%), and next are, in order of incidence, accidents due to fall from height, simple fall(19%), exercise(12.6%), gun shot wound or explosive injury(9.4%) and assault(9.4%). 3) Skull fracture were seen in 115 cases(72.3%), and nearly half of those 55 cases, were linear fracture. 4) Of the 133 patients with intracranial hematoma or subdural hygroma, 88 cases(66.7%) were accompanied by skull fracture. 93% of epidural hematomas were associated with skull fracture and the most common wite of hematoma was temporoparietal area. 5) Of all cases of subdural hematoma, acute type was prevalent(59.4%) and its main site involved was temporoparietal area. 6) The associated injuries were found in 22.6% of patients. The frequent ones were facial bone fracture, upper extremity fracture, clavicle fracture, and chest injury, in order. 7) The minor head injury of Glasgow coma scale score(GCS) of 13 to 15 was 68 cases(42.8%). The moderated head injury of 9 to 12 was 28 cases(17.6) and the serve head injury of 3 to 8, 63 cases(39.1%). 8) The operation mortality was 26.8% and the good recovery was achieved 55.4% of patients. The remaining 18.8% resulted in disabled or vegetative state. 9) In the accidents of gun shot wound or explosive injury, operation mortality rate was 60%, but 5 cases(33.3%) were seen good recovery.

Though the lung is the main site of infection with Paragonimus Westermani, during the migration periods of the larva, any place of the body including brain, orbit, liver, intestinal wall, diaphragm, subcutaneous tissues, and etc. may be infected with the larva. But the ectopic Paragonimus westermani in the scrotum is very rare instance. Recently, we found an ectopic Paragonimus westermani in the scrotum from 55 years old male patient who admitted to our hospital under the impression of scrotal mass. Although the histopathological findings bore some resemblance to the changes of the infection with tuberculosis, the definite clue in differentiation from tuberculosis was the discovery of the adult worm and eggs of the Paragonimus westermani in the lesions.

We performed the radioimmunoassay to detect the hepatitis B surface antigen(HBsAg) in the tear. Among 70 patients who have positive reactions for HBsAg in blood, 53 patients(75.71%) were positive for HBsAg in tear. Among the various groups of hepatitis, the most positive reaction for HBsAg in tear was higher in serum HBeAg positive group(92.68%) than in serum HBeAg negative group(51.72%). So we emphasize the possibility of transmission of hepatitis B virus infection via tear.

A retrospective analysis of CT and MR findings was performed in five patients with histologically proved chordoma including one with chondroid chordoma. All tumors were mostly isodense to gray matter on unenhanced CT, and the single intensities were iso or low and high on T1 and T2-wgighted MR iages, respectively. The tumors had an increase in their density on enhanced CT and MR in four patients, but a chondroid chordoma was poorly enhanced after injection of contrast medicum on CT. Four tumors contained calcifications in CT images and two lesions showed hemorrhage in MR images. Cavernous sinus was involved in all patients, and brain stem and basilar artery were compressed by the tumors in three cases. Pituitary gland was only displaced upward in three patients. Clivus was destroyed in all cases, and sella turcica and sphenoid bone were involved in three patients. CT is better than MR in demonstrating calcifications and bone destruction. In defining the extension of tumor, MR appears to be superior to CT in evaluation of the relationship between the tumor and the surrounding structures.

BACKGROUND AND OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is known to induce chronic rhinosinusitis (CRS). Nasal polyp, which is frequently found in patients with CRS, seems to have close relationship with COPD, but little is known about its relationship with COPD. In this study, we investigated the relationship between COPD and nasal polyp in middle aged and elderly CRS patients. SUBJECTS AND METHOD: We analyzed the clinical data of 174 patients (age of over 50 years) with CRS. Patients were divided as COPD [forced expiratory volume (FEV1)/forced vital capacity (FVC)<70%, n=30] and non-COPD group (FEV1/FVC≥70%, n=144) according to the pulmonary function test results. Binary logistic regression analysis was used to describe the relationships between clinically relevant factors related to nasal polyp. RESULTS: On logistic regression analysis, no significant relationship was found between age [adjusted odds ratio (AOR): 1.058, 95% confidence interval for the difference (CI)=0.995-1.126, p=0.073], sex AOR: 0.897, 95% CI=0.366-2.415, p=0.897), smoking (AOR: 0.434, 95% CI=0.154-1.219, p=0.113) and obesity (underweight AOR: 3.833, 95% CI=0.781-18.808, p=0.098, overweight AOR: 5.169, 95% CI=0.996-26.814, p=0.051, obese AOR: 2.911, 95% CI=0.335-25.329, p=0.333) with polyp. However, there was a negative correlation between COPD history and nasal polyp with statistical significance (AOR: 0.288, 95% CI=0.102-0.809, p=0.018). CONCLUSION: Our findings suggest that patients with COPD are less likely to have nasal polyp than patients without COPD.

Bovine viral diarrhea virus (BVDV) is an RNA virus belonging to Pestivirus in the family Flaviviridae. BVDV has economic significance for the livestock industry because of its association with acute disease, fetal loss, and birth of persistently infected (PI) animals. This study aimed to investigate the BVDV infection rates in Korean native cattle farms in Jeju for further planning of a BVDV control program in the Jeju Province. BVDV antibodies and antigens were tested in 15,842 sera collected from 302 Korean native cattle herds between January 2014 and June 2017 using enzyme-linked immunosorbent assay (ELISA). Viral antigen was detected by reverse transcription-polymerase chain reaction from 60 sera that were antigen ELISA-positive. BVDV antibodies were found in 90.7% (274/302) herds and 61.1% (9,678/15,842) cows. BVDV antigens were found in 13.2% (40/302) herds and 0.4% (61/15,842) cows. The oldest animal group (> 8 years) exhibited the highest sero-positive rates (91%), while the youngest animal group (< 1 years) had the highest antigen positivity rates (0.52%). Of the 60 antigen-positive sera, BVDV types 1 and 2 were found in 36 and 12 sera, respectively. Additionally, six animals were considered to be PI as BVDV was continually detected in annual examination.
