OBJECTIVE: Frozen-section evaluation of gynecologic tumors has historically been used to establish a histopatholgic diagnosis and to guide surgeons in appropriate surgical procedure. this study is to assess the clinical appropriation and accuracy of frozen-section biopsy in gynecologic tumors. METHODS: This is a retrospective quality assurance study all of frozen-section biopsy done at Chungnam National University Hospital during a three year period (1995 to 1997). There were 125 cases out of 2310 surgical specimens for gynecologic tumors, and the results were compared with final diagnoses based on fixed tissue specimens. RESULTS: Frozen section biopsy was accurate in 95.2% of all cases, in 96.3% (104/108) of ovarian tumor cases, and in 88.2% (15/17) of uterine tumor cases. Analysis of 6 inaccuracy cases revealed that most cases were sampling errors and occurred in mucinous tumor, belonging to all cases of ovarian tumors. Sensitivity, specificity, positive predictive value, and negative predictive value of frozen-section biopsy in ovarian tumors were 0.94, 1.00, 1, 00, 0.97. CONCLUSION: Frozen section biopsy is an appropriate method as a basic guideline during operations of gynecologic tumors and this method can obtains the highest accuracy when there is cooperation between experienced surgeons and reliable and careful pathologists. The accuracy of frozen section diagnosis has important implications regarding the type and extent of the primary surgery for gynecologic tumors.

We describe a case of eosinophilic pustular folliculitis in a 1-month-old Korean male infant. The patient was suffering from erythematous papules and pustules affecting the scalp, trunk, and extremities, detected at birth. The flare was accompanied by leukocytosis and eosinophila. Histopathology revealed folliculitis with a predominant eosinophilic infiltrate. Lesions showed partial response to topical steroid and disappeared in four weeks. Three months after the resolution of the lesions, he presented a similar clinical picture as the previous episode.

During a period of 5 years and 3 months, from January, 1980 to march, 1985, 42 cases of ventricular septal defects were observed to be closed spontaneously during their follow up period and were evaluated at pediatric department, hanyang University hospital. 1) Sex incidence shows female preponderance with male to female ration of 1:2. 2) The mean age when they were diagnosed as ventricular septal defect was 5.0+/-6.4 months, and that of VSD murmur last noted was 13.3+/-11.5 months. The mean age when typical VSD murmur disappeared due to spontaneous closure of the defects was 21.1+/-18.7 months. Spontaneous closure of ventricular septal defects disclosed under one year in 22 cases (52.4%). Of those 22 cases, ventricular septal defects were spontaneously closed under 6 months of age in 16 cases(38.8% of whole study population). From the whole study population 90.5%(38 cases) were spontaneously closed under the age of 5 years. 3) Major clinical and physical characteristics before spontaneous closure of ventricular septal defects were typical pansystolic murmur with maximum intensity at left lower sternal border in all cases, palpable thrill in 5 cases(12.8%), ventricular heaves in 4 cases(10.2%) and frequent respiratory infection histories in 27 cases(64.3%). 4) Electrocardiographic findings when they were initially presented as ventricular septal defects revealed normal axis in 28 cases(84.8%), left axis deviation in 3 cases(9.1%), right axis deviation in 2 cases(6.1%) as frontal QRS axis and left ventricular hypertrophy in 8 cases(24.2%), right ventricular hypertrophy in 5 cases(15.6%) and biventricular hypertrophy in 3 cases(8.7%). Other electrocardiographic abnormalities when they had ventricular septal defects were left atrial enlargement in 12 cases(36.4%) and intraventricular conduction delay in 12 cases(36.4%). After spontaneous closure of ventricular septal defects, the electrocardiographic findings revealed normal axis in 36 cases(92.3%), left axis deviation in 3 cases(7.7%) and left ventricular hypertrophy in one case(2.6%). The remaining abnormalities after spontaneous closure of ventricular septal defect were intraventricular conduction delay in 14 cases(35.9%), deep SV6 in 4 cases(10.3%), tall RV6 in 5 cases(12.8%) and long QTc in 1 case(2.6%). Thirty-eight cases(97.4%) do not show ventricular hypertrophy pattern in EKG after spontaneous closure of their defects. 5) When we analyse their frontal plain chest X-ray films after spontaneous closure of ventricular septal defects, cardiomegaly(cardiothoracic ratio)55%) noted in 7 cases(17.9%) and pulmonary plethora in 5 cases(12.8%);while those before the defect were closed spontaneously were 67.6% and 64.7%, respectively. 6) Among 26 cases who underwent follow up 2 dimensional echocardiographic study so-called septal aneurysm were noted with the process of spontaneous closure of ventricular septal defects in 15 cases(57.7%) and the remaining 11 cases do not have any evidence of 'septal aneurysm' even after the completion of spontaneous closure of their defects. In the patient group with so-called 'septal aneurysm' the proportion of female sex was 60% and early systolic clicky sound were heard in 9 patients from 15 cases(60.0%), while those without 'septal aneurysm'were 55% and 18.2%, respectively.

The radiologic findings of lumbosacral spine and measurement of lumbosacral angle were analysed in 238 with backache and 102 without backache which were visited at Chungnam National University from March 1980 to July 1981.The measurement of lumbosacral angle was based on a method of Fergson. The results obtained were as follows; 1. The age group of 18 to 29 years was most common in backache group and the male was affected more frequently than the female with the ratio of 1.9 to 1. 2. In patients with backache, the overall mean lumbosacral angles were 44.2±2.6 degrees in male and 35.8±2.0 degrees in female. In patients without backache, in control group, the overall mean lumbosacral angles were 32.6±0.7 degrees in male and 33.4±1.4degrees in female. 3. In control group, difference of means between male and female was about 1degrees in patients with backache, the overall mean lumbosacral angles were increased about 12degrees in male and 2degrees in female than control group. In patients with and without backache, no significant difference of lumbosacral angle between the 4 age groups was present. 4. In backache group, increased lordosis was more common and increased lumbosacral angle than the decreased lordosis. 5. In backache group, lumbosacral angle of abnormal radiologic findings in lumbosacral spine was significantly increased than control group. 6. In patients with backache, radiologic findings and its lumboscral angles were alumbosacral anomaly 56 cases (23.5%): 46.9 degrees, increased lumbar lordosis 46 cases (19.2%): 48.1 degrees, osteoarthritis 44 cases(18.5%) : 40.8 degrees, decreased lumbar lordosis 30 cases (12.6%): 29.9 degrees, in order, And these radiologic findings were similar with many other authors.

BACKGROUND: This study was aimed to elucidate the effect of thiopental anesthesia on circulatory response to hemorrhage in rats by power spectral analysis of heart rate and blood pressure variability. METHODS: Sixteen male Sprague-Dawley rats weighing 350~475 g were divided into thiopental (50 mg/kg, ip)-anesthetized (T, n=10) and conscious (C, n=6) groups. Hemorrhage was induced with a withdrawal pump from the femoral artery at 3 ml/kg/min for 5 min. Arterial pressure was measured with a pressure transducer connected to the contralateral femoral artery for 5 min before, during and after hemorrhage. The blood pressure signal digitized at 500 Hz through a data acquisition system was analyzed with fast Fourier transform algorithm to yield power spectra of sytolic (SP) and diastolic (DP) blood pressure and instantaneous heart rate (HR). Powers of very low frequency (VLF, 0.02~0.26 Hz), low frequency (LF, 0.26~0.75 Hz) and high frequency (HF, 0.75~5.00 Hz) band were expressed as percent of total power. RESULTS: Before Hemorrhage blood pressure was lower in T (113 6/83 6 mmHg) than in C (157 4/101 2) rats, but was not changed by hemorrhage in both groups. Before Hemorrhage HR was lower in T (331 22 beats/min) than in C (378 27) rats. HR was significantly increased to 412 26 beats/min in C, but was not changed in T during hemorrhage. Total powers of Before Hemorrhage blood pressure and HR variability were lower in T than in C. During hemorrhage, total power of blood pressure variability tended to increase in both groups, and that of DP was significantly increased during hemorrhage in T. Total power of HR was significantly increased in C, but was not changed in T. T rats showed lower LF and higher HF power of blood pressure, and lower VLF and LF and higher HF power of HR than C rats. During hemorrhage, both groups showed no significant change in spectral distribution of HR power, except for a significant increase in LF of HR after hemorrhage in C. Spectral distribution of blood pressure power was not changed by hemorrhage in C. In T rats, VLF of DP was significantly increased and HF of DP was decreased during hemorrhage. CONCLUSIONS: It suggests that autonomic activity, especially cardiac sympathetic activity is increased in response to hemorrhage in C. Thiopental anesthesia depresses overall autonomic activity, especially sympathetic activity, and vasomotor tone. Hemorrhage under thiopental anesthesia induces depression of baroreceptor reflex activity, while increased levels of vasoconstrictor hormones help to maintain the blood pressure.
