1.Biologic Significance of Hepatocyte Hepatitis B Core Antigen Expression in Chronic Hepatitis B Virus Infection.
Korean Journal of Pathology 1989;23(3):287-291
To elucidate the biologic significause of hepatocyte B core antigen (HBcAg) expression and its relation to the natural course of hepatitis B virus (HBV) infection, we tried to correlate the patterns of HBcAg with the HBV replication state and with disease activity in 40 needle biopsies performed on hepatitis B surface antigen (HBsAg) carriers aged from 15 to 46 years. In 32 of 40 cases, HBcAg was present in the hepatocyte nucleus (nHBcAg), in the cytoplams (cHBcAg) or in both (mixed). Pure nHBcAg was seen only in minimal hepatitis, but a diffuse pattern of expression of cytoplasmic HBcAg and mixed cytoplasmic and nuclear expression of HBcAg were seen in active hepatitis. There was also a good correlation between liver HBcAg and serum HBeAg. Cases in which HBcAg expression were observed were positive for serum HBeAg (81%) and the cases negative for HBcAg were all positive for serum anti-HBe.

OBJECTIVES: This study was to determine whether drainage after radical hysterectomy and bilateral pelvic lymphadenectomy can reduce the risk of postoperative morbidity as compared with no drainage. METHODS: 165 patients with stage Ia2 to Ilb underwent radical hysterectomy and bilateral pelvic lymphadenectomy between January 1995 and May 1997, and those medical records were analyzed, Closed suction drains were placed in group I (n 102), not in group II (n 67). All surgeries were perforrned by the same surgeon in a uniform method. RESULTS: The characteristics of two groups were similar for mean age, preoperative weight, total protein, serum albumin, tumor cell histology, invasion depth, and tumor stage. There was no difference in mean operation time in two groups. But mean estimated blood loss was more in group I than group lI(p<0.05), Postoperative ileus and postoperative stay was similar in both groups. The incidence of pelvic lymphocyst and febrile morbidity in two groups were comparable with 17% in group I and 27% in poup II, but not statistically significant(p>0.05). Rehospitalization rate was higher in group I than in group II. CONCLUSION: Pelvic drainage didn't reduce the postoperative febrile morbidity and lymphocyst formation. Therefore the author could not find any necessity to perform the drainage following radical hysterectomy and pelvic lymphadenectomy.

Nezelof's syndrome(combined immunodeficiency with immunoglobulin) is a hereditary primary immunodeficiency characterized by recurrent chronic pulmonary infections, oral and cutaneous candidiasis, failure to thrive, chronic diarrhea, skin infection, urinary tract infection, gram-negative sepsis, severe progressive varicella infection, lymphopenia, diminished lymphoid tissue, abnormal structure of the thymus, and presence of normal or increased levels of one or more of the major immunoglobulin classes, but with impaired antibody synthesis. We experienced a case of Nezelof's syndrome in 5-month-old boy who complained cough, poor feeding, vomiting and diarrhea in first admission day and discharged with recovered general condition in 38th admission day and then died of recurrent bacterial and fungal infections and malnutrition in 15-month-old age. He had no thymic shadow in chest X-ray and immunologic abnormalities including decreased lymphocyte count, decreased T cell count and function, normal number of B cell count and immunoglobulins with funtional impairment in antibody synthesis. We report a case of Nezelof's syndrome with brief review of related literatures.

BACKGROUND: In Korea, the prevalence of tuberculosis and hepatitis is high, and combined therapy with rifampicin and pyrazinamide is used in tuberculosis, so drug induced hepatitis is not only problem of tuberculosis therapy but also cause of treatment failure. However most of recent reports on drug induced hepatitis during antituberculosis medication have dealt with its pathogenesis and have stressed the biochemical, and histopathological aspects of the disorder, whereas this study was designed primarily to provide information on the clinical features. METHOD: The subjects of study were 1414 patients treated with antituberculosis drugs on the department of chest medicine at National Medical Center during the 5-year 6-month period from January 1, 1988, to June 30, 1993. Retrospective analysis of clinical features for the 29 patients who developed drug induced hepatitis was done. RESULTS: 1) The incidence of antituberculosis drug induced hepatitis was 2.1%. 2) Male to female ratio of antituberculosis drug induced hepatitis was 2:1, but case rates among males and females were not significantly different. 3) Rates of drug induced hepatitis according to age distribution shows the most common incidence between 35 to 49 year old age group, but rates among groups of age were not significantly different. 4) Drug induced hepatitis was most common in the case of moderate advanced Pulmonary tuberculosis(rate is 2.78%), but rates among types of tuberculosis were not significantly different. 5) 18 cases(62%) of antituberculosis drug induced hepatitis patients had no signs or symptoms. In remaining cases, they were nausea, vomiting, jaundice, hepatomegaly, icteric sclera, right upper quadrant -tenderness in order 6) 22 cases(76%) of antituberculosis drug induced hepatitis cases had occurred within the first month. 7) The duration of abnormal liver function was 28±5(Mean±SD), ranged from 5 days to 180 days. 8) One case of antituberculosis drug induced hepatitis died. 9) The levels of abnormal GOT ranged from 64 to 1055U/L and GPT from 68 to 931U/L. CONCLUSION: There are no decided predisposing factors of antituberculosis drug induced hepatitis, so it should be done biochemical monitoring as week as close monitoring for overt signs or symptoms of hepatitis to avoid the development of irreversible hepatic reaction, especially at the treatment of the first month.

Infantile digital fibromatosis(IDF) is a rare, benign fibrous tumor, first described in 1965 by Reye. IDF may occur single or multiple lesions exclusively on the fingers or toes, rare occurrence outside the digit have been reported. This tumor grow slowly and may adhere to the deeper tissue, and may lead to deformity of the digit, but do not distant metastasis or dissemination. There is a marked tendency for recurrence after surgical excision. Up to now, only 6 cases have been reported in the literature showing spontaneous regression. We experienced a case of infantile digital fibromatosis located on hypothenar area at birth. Also that spontaneous regressed at 13 months of age. We reported a case of IDF showing spontaneous regression with brief review of related literature.

PURPOSE: To evaluate the inter observer variation in interpretation of the mammographic findings suggesting malignancy. MATERIALS AND METHODS: Sixty-two mammograms of proven breast cancer were retrospectively analyzed by5 radiologists based on the 15 findings that suggest malignancy. Using kappa value, the degree of interobserver agreement was calculated. RESULTS: There were fair to excellent interobserver agreements for 5 findings which were clustered microcalcifications(k=0.7642), ductal calcifications (k=0.5463), lobulated mass(k=0.4539), asymmetric breast parenchyma (k=0.4487) and nipple retraction(k=0.4061). The finding in which kappa value was lessthan 0.2 were intramammary lymph node(k=0.1572), duct ectasia(k=0.1453), phleomorphic calcifications(k=0.1309), architectural distortion(k=0.1247) and stellate mass(k=0.0200). CONCLUSION: The most reliable finding suggesting breast cancer was clustered microcalcifications.

STATEMENT OF THE PROBLEM: In cases of low bone level in maxilla followed by extraction due to severe periodontitis or enlarged maxillary sinus, crown-root ratio of implant prosthesis will increase. The prognosis of these cases is not good as expected. PURPOSE: The purpose is to compare stress distribution due to crown-root ratio and effect of splinting between two implants in maxillary molar area under different loads MATERIAL AND METHODS: Using ITI(4.1 x 10 mm) implant, two finite element models were made(model S: two parallel implants, model A: one of two is 20 degree inclined). Each model was designed in different crown-root ratio(0.7:1, 1:1, 1.25:1) and set cement type gold crown to make it splinted or non-splinted clinical situations. After that, 300 N force was loaded to each model in four ways.(load 1 : middle of occlusal table, load 2 : middle of buccal cusp, load 3 : middle of lingual cusp, load 4 : horizontal load to middle of buccal cusp), and stress distribution was analyzed. RESULTS: On all occasions, stress was concentrated on neck of implant near cortical bone. In the case of inclined implant, stress was increased compared with parallel implants. Under load 1, 2, 3, stress was not increased even when crown-root ratio increases, but under load 4, when crown-root ratio increases, stress also increased. And more stress was concentrated under load 1 than load 2, 3. When crown-root ratio was same, stress under load 1, 2, 3 decreased when splinting, but under load 4, stress did not really decrease. CONCLUSION: Under vertical load, stress distribution related to crown-root ratio did not change. But under horizontal load, stress increased as crown-root ratio increases. Under vertical load, splinting decreased stress but under horizontal load, effect of splinting was decreased as condition of implant changes for the worse such as increase of crown-root ratio, inclined implant.
