OBJECTIVE: The purpose of this study was to assess the role of HPV 16 and 18 in adenocarcinoma in situ(ACIS) of the uterine cervix. METHODS: Seventeen cases of primary cervical adenocarcinoma in situ were analyzed for HPV DNA by polymerase chain reaction. HPV 16 and 18 DNA extracted from formalin-fixed, paraffin-embedded histologic tissue sections by polymerase chain reaction. RESULTS: 35.3% and 23.5% of ACIS were positive for HPV 16 and HPV 18 DNA, respectively. From the normal tissue, 11.8% were positive for HPV 16. Human papillomavirus positive patients were younger than negative patients but statistically insignificant(mean age 42.1 vs 51.7 years). CONCLUSIONS: These results show that HPV type 16 and 18 were closely related to etiology of the ACIS of the uterine cervix.

The hepatitis C vims(HCV) is now known to be the chief cause of transfusion-associated non-A, non-B hepatitis. The ultimate goal of blood donor screening for anti-HCV antibodies is the specific exclusion of vital carriers from the blood donor population. Recently, a third generation anti-HCV screening(Green Cross Center Innotest HCV 3.0 Genedia HCV 3.0 ) and immunoblot assay, Inno-Lia HCV Ab III (Innogenetics) using antigens derived from the core and different nonstructural regions(NS3, NS4 and Ns5) of the HCV viral genome were developed. To evaluate the usefulness of these assays, anti-HCV reaction patterns of the Inno-Lia HCV Ab III or presence of HCV-RNA detected by reverse transcriptase-polymerase chain reaction(RT-PCR) were examined samples in which were repeatedly positive or discrepant with Abbott EIA-2, Innotest HCV 3.0 Genedia HCV 3.0 The reaction intensity of Innotest HCV 3.0 Genedia HCV 3.0 was higher than that of Abbott EIA-2. The sensitivity and specificity of Innotest HCV 3.0 and Genedia HCV 3.0 were 92.9% and 86.8%, respectively, and the positive and negative predictive values were 72.2% and 97.1%. both. The sensitivity and specificity of Abbott EIA-2 were 100% and 78.9%, respectively, and the positive and negative predictive values were 63.6% and 100%, respectively. We concluded that the new third generation HCV EIA reagents can decrease a false positivity of second generation EIA reagents and correlate well with detection of HCV-RNA by RT-PCR.

BACKGROUND: Although there are several methods for evaluating bone quality, Hounsfield units (HU), a standardized computed tomography (CT) attenuation coefficient, provide a useful tool for estimating focal bone mineral density (BMD). The aim of this study is to investigate the HU for evaluating the degree of osteoporosis in greater tuberosity with regard to anchor positioning. METHODS: Forty patients diagnosed as normal on shoulder CT were included and categorized according to age and gender. Axially sectioned CT images were processed to 3-dimensional models containing information about bone quality using Mimics (14.11 platform v14.1.1.1 Materialise). Three-dimensional anchors were simulated and positioned according to 6 regions of interest (ROI) in the greater tuberosity classified using Tingart's system. Mean HU of intra-anchor volumes in the 6 regions was measured. RESULTS: A significant decrease in HU was observed with increasing age (p=0.0001) and menopause (p<0.001). A significant difference in HU was found between male and female groups with males showing the higher values (p=0.0001). HU of proximal areas of ROI was higher than those of distal areas (p<0.005). However, although mean HU of distal posterior ROI showed the lowest values, no statistically significant difference was found between anterior, middle, and posterior regions (p=0.087). CONCLUSION: Mean HU of ROIs provides a tool for preoperative assessment of focal BMD, which is a factor of suture anchor stability and can be used to aid decision-making regarding secure anchor positioning for rotator cuff repair. Our data support that the most secure point is the proximal regions of ROI.

BACKGROUND: For the evaluation of pulmonary nrtery branches after operation of right ventricular outflow obstructive disease, we reviewed the usefulness of both simple X-ray and lung perfusion scan with 99mTc-macroaggregated albumin compared with cardiac angiography. METHODS: From March, 1986 to July, 1993, at Seoul National University Children;s Hospital, we chose 23 cases who underwent both simple X-ray and cardiac angiography among the patients who had distinct difference between right and left pulmonary blood flow in lung perfusion scan after operation of right ventricular outflow obstructive disease. So we calculated the ratio of right and left pulmonary blood flow and Spearman correlation coefficient. RESULTS: Of the 23 cases, 17 cases were tetralogy of Fallot, 4 cases pulmonary atresia, 1 case double outlet right ventricle, and 1 case truncus arteriosus. The mean age at poeration was 27 months, and the mean postoperative follow-up period was for 68 months. The correlation coefficient between cardiac angiography and simple X-ray was 0.86(p<0.01), and that beteen cardiac angiography and lung perfusion scan was 0.80(p<0.01). CONCLUSION: The cardiac angiography has been known as the best diagnostic tool for the evaluation of pulmonary artery branches after operation of right ventricular outflow obstructive ddisease, but we proposed that the lung perfusion scan should be widely used because its results were similar with those of cardiac angiography.

Tuberculosis of the vagina is very rare disease reported to be involved in less than 1% of female genital tuberculosis. A 53-year-old woman presented with abnormal cervicographic finding at the private clinic. On vaginal physical examination, there were multiple elevated nodular lesion in the vagina and ectocervical area. There was no abnormal vessels or acetowhite epithelium on colposcopic examination. Direct biopsy for histologic examination revealed granulomatous lesion. We performed PCR of mycobacterial DNA and Ziehl-Neelsen staining for acid-fast bacilli (AFB). The Ziehl-Neelsen staining for AFB was negative, but mycobacterial DNA fragments were detected using the PCR method. Diagnosis was confirmed by the detection of acid-fast bacilli in histologic preparations. Anti-tuberculosis medication was effective for this patient.

BACKGROUND: Autoimmune hemolytic anemias are characterized by autoantibodies recognizing antigens on the Individual's own red blood cells, resulting in immune- mediated hemolysis. Blood transfusions have been regarded as hazardous in patients with autoimmune hemolytic anemia (AIHA) because of potential intensification of hemolysis and a presumed high incidence of alloimmunization. METHODS: We examined the pretransfusion and posttransfusion hemoglobin levels in 6 patients with autoantibodies in their sera, which showed panagglutinations with all bloods tested in the compatibility testing. They received 'least' incompatible blood because of inability to find compatible blood. RESULTS: When we compared pretransfusion hemoglobin level with posttransfusion hemoglobin level, in 5 of 6 patients with AIHA, the hemoglobin levels were increased after red cell transfusion. 4 patient who did not respond to transfusion therapy initially had an increase in hemoglobin level after steroid treatment. Any signs or symptoms indicating hemolytic transfusion reaction were not observed ducting the transfusion period in all patients. CONCLUSIONS: The decision to transfuse in AIHA should consider multiple factors including the patient's clinical status, the potential benefit of transfusion, the potential response to other therapeutic modalities, but must never be regarded as contraindicated, even though the compatibility test may be strongly incompatible.
