Objectives: To determine whether the clinical aspect of aplastic anemia is influenced by pregnancy. METHODS: We reviewed 37 cases of pregnant aplastic anemia patients during Jan. 1989 to Dec. 1998, and examined age, parity, progress of pregnancy, termination methods, obstetrics & neonatal complications, hematologic change, and treatment modality by medical records. RESULTS: According to onset of disease, patients were divided into pre-pregnant diagnosed group(n=12) and during-pregnancy diagnosed group(n=25). Mean age of diagnosis was 29.4yr, 89.2% were nulliparous, and 51.4% were severe aplastic anemic patients. All patients underwent 50 pregnancy. Mean gestational period was 37wks, birth weight was 2569gram, and, except in 7 cases of abortion, 43 cases were delivered transvaginally or transabdominally(51.2% vs. 48.8%). Preeclampsia, eclampsia, preterm labor, restricted growth, and distress were complicated and decreased hemoglobin, hematocrit, reticulocyte, platelet were reversed after termination in pregnancy associated group. Treatment modality during pregnancy included transfusion, steroid, anti-lymphocytic globulin, anti-thymocytic globulin and IVGV, and remission rate was 45.5% in pregnancy associated group. CONCLUSION: We concluded that pregnancy is associated with aplastic anemia as a high risk factor, and intensive treatment is needed.

Tuberculosis of the breast is a rare disease. Its diagnosis is difficult because clinical and radiological appearances are not specific and because isolation of the tubercle bacillus from the lesion is seldom possible. This disease is more common in women between 20 to 40 years of age, but is rare in male, elderly patients and prepubertal women. Difinite diagnosis rests on bacterilogical proof and histopathological findings -formation of a granuloma and usually caseous necrosis with or without demonstrable acid-fast bacilli. Treatment of the disease requires a combination of surgery and antitubercular drugs. We experienced 10 cases of tuberculosis of the breast and report with on them along a literature review.

PURPOSE: To evaluate the result of forearm shaft fracture treated by modified interlocking intramedullary nail (Acumed, Hillsbrough, IN, USA). MATERIALS AND METHODS: 15 patients with fracture of radius, ulna, radio-ulna shaft treated by modified interlocking intramedullary nail from December 2003 to February 2007 were analyzed. Modified interlocking intramedullary nail has paddle blade tip and fluted rod, so the distal screw fixation was not needed but had relatively firm fixation. It has advantages including short operation time, small operation scar. The average follow up period was 8.3 months (range, 5~15 months). We analyzed the results by average union time and the functional results according to Anderson's criteria. RESULTS: The mean duration of union was 9.8 weeks in radius and 11.4 weeks in ulna. The average range of motion of forearm was 74.6 degree in supination and 72 degree in pronation.. Functional results assessed by Anderson were rated excellet in 12 cases, satisfactory in 3 cases. We found no complications such as delayed union, non-union, neurovascular injury and infection. CONCLUSION: Modified interlocking intramedullary nail (Acumed, Hillsbrough, IN, USA) is a viable therapeutic alternative in the management of forearm shaft fracture.

Background/Aims: Increasing resistance to clarithromycin (CAM) of Helicobacter pylori (H. pylori) is one of the main causes of recent decrease in eradication rate of standard triple therapy. The aim of this study was to evaluate the usefulness of 7-day tailored therapy based on the existence of CAM resistance. Methods: From January 2017 to May 2022, a total of 481 consecutive patients with H. pylori infection were recruited in Daegu Catholic University Medical Center. Treatment regimen was selected based on the result of CAM resistance test. Patients with CAM resistance (R group) were treated with bismuth-based quadruple therapy for 7 days. Patients without CAM resistance (S group) were treated with standard triple therapy for 7 days. Results: The overall H. pylori eradication rate was 89.4% (379 of 424) by per-protocol (PP) analysis. Patients with CAM resistance mutation included 166 patients (34.5%). The eradication rates of each group were 88.8% (135 of 152) and 89.7% (244 of 272) by PP analysis, for R and S group respectively. By intention-to-treat (ITT) analysis, the eradication rates were 81.3% (135 of 166) and 77.5% (244 of 315) for R and S group. CAM resistance was identified with a dual-priming oligonucleotide-based multiplex PCR. Conclusions In spite of this high CAM resistance (34.5%), the eradication rate of 7-day tailored therapy based on the existence of CAM resistance was 89.4%. The 7-day tailored therapy based on CAM resistance could be an acceptable treatment selection strategy for H. pylori eradication.

BACKGROUND: Oxytocin (OXT) has been reported to act as a growth regulator in various tumor cells. However, there is a paucity of data on the influence of OXT on cell proliferation of corticotroph adenomas. This study aimed to examine whether OXT affects cell growth in pituitary tumor cell lines (AtT20 and GH3 cells) with a focus on corticotroph adenoma cells. METHODS: Reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assay were conducted with AtT20 cells to confirm the effects of OXT on hormonal activity; flow cytometry was used to assess changes in the cell cycle after OXT treatment. Moreover, the impact of OXT on proliferating cell nuclear antigen (PCNA), nuclear factor κB, and mitogen-activated protein kinase signaling pathway was analyzed by Western blot. RESULTS: OXT treatment of 50 nM changed the gene expression of OXT receptor and pro-opiomelanocortin within a short time. In addition, OXT significantly reduced adrenocorticotropic hormone secretion within 1 hour. S and G2/M populations of AtT20 cells treated with OXT for 24 hours were significantly decreased compared to the control. Furthermore, OXT treatment decreased the protein levels of PCNA and phosphorylated extracellular-signal-regulated kinase (P-ERK) in AtT20 cells. CONCLUSION: Although the cytotoxic effect of OXT in AtT20 cells was not definite, OXT may blunt cell proliferation of corticotroph adenomas by altering the cell cycle or reducing PCNA and P-ERK levels. Further research is required to investigate the role of OXT as a potential therapeutic target in corticotroph adenomas.

BACKGROUND: Adverse transfusion reactions (ATRs) are clinically relevant to patients with significant morbidity and mortality. This study aimed to review the cases of ATR reported in the recipient-triggered trace back system for a recent nine-year period in Korea. METHODS: Nine-year data obtained from 2006 to 2014 by the trace back system at the Division of Human Blood Safety Surveillance of the Korean Centers for Disease Control (KCDC) were reviewed. The suspected cases were assessed according to six categories: (i) related to, (ii) probably related to, (iii) probably not related to, (iv) not related to transfusion, (v) unable to investigate, and (vi) under investigation. RESULTS: Since 2006, 199 suspected serious ATRs were reported in hospitals and medical institutions in Korea, and these ATRs were reassessed by the division of Human Blood Safety Surveillance of the KCDC. Among the reported 193 cases as transfusion related infections, hepatitis C virus (HCV) infection (135, 67.8%) was reported most frequently, followed by hepatitis B virus (HBV) infection (27, 13.6%), HIV infection (13, 6.5%), syphilis (9, 4.5%), malarial infection (4, 2.0%), other bacterial infections (3, 1.5%), HTLV infection (1, 0.5%), and scrub typhus infection (1, 0.5%), respectively. Of the 199 cases, 13 (6.5%) cases were confirmed as transfusion-related (3 HCV infections, 3 malarial infections, 1 HBV infection, 2 Staphylococcus aureus sepsis, 3 transfusion-related acute lung injuries, and 1 hemolytic transfusion reaction). CONCLUSIONS: This is the first nationwide data regarding serious ATRs in Korea and could contribute to the implementation of an effective hemovigilance system.

OBJECTIVES: To investigate the role of annexin-I in human cervical cancer, we evaluated the expression of annexin-I and the relation with the proliferation of cancer cells. Methods: By immunohistochemical analysis and the western blotting of annexin-I , we investigated the extent and distribution of the expression of annexin-I in cervical cancer tissues. After treating the human cancer cell lines ( SiHa and HeLa cell lines ) with tamoxifen, estradiol, and retinoic acid for 5 days to make the cells proliferate and antiproliferate, we measured the proliferation simultaneously with 3-(4,5- dimethyl thiazol- 2-yl)-2,5-diphenyl-tetr -azolium bromide (MTT) colorimetric assay and the expression level of annexin-I with flowcytometry. RESULTS: In the immunohistochemical stains, a granular staining pattern involving the entire cytoplasm was more heavily observed in malignant lesions than in normals. In the western blotting, the antibodies against 35-kDa annexin-I appeared to react more strongly with the lysates of cancer tissues than normal and benign tissues. In SiHa and HeLa cell lines with tamoxifen and beta- estradiol treatment, increased expressions of annexin-I were noted with correlated increased proliferation of cells, and with the treatments of all trans retinoic acid, decreased expressions of annexin-I were noted with correlated decreased proliferation of cells. CONCLUSIONS: The results suggest that the expression of annexin-I might correlate with cervical cancer than normal and the proliferation of cancer cells.

The functionally generated path (FGP) technique, first described by Meyer in 1933, is a method in the oral cavity to use the movement pathway formed by the opposing cusps within the border movement of the mandible. Using this method, an appropriate occlusal shape can be given to the patient. In this case, the FGP technique was selected to provide a bilateral balanced occlusion when restoring the edentulous maxilla that opposes the natural mandibular teeth with irregular arrangement with overdentures. In addition, in order to precisely form the occlusal surface of the posterior region with the FGP technique and to reduce the attrition of denture teeth, zirconia denture teeth, not conventional resin artificial teeth, were individually manufactured. After treatment with these materials and methods, satisfactory results were obtained for both the operator and the patient.

Background/Aims: The diagnosis of intestinal tuberculosis (Itbc) is often challenging. Therapeutic anti-tubercular trial (TATT) is sometimes used for the diagnosis of Itbc. We aimed to evaluate the changing pattern of fecal calprotectin (FC) levels during TATT in patients with Itbc. Methods: A retrospective review was performed on the data of 39 patients who underwent TATT between September 2015 and November 2018 in five university hospitals in Daegu, South Korea. The analysis was performed for 33 patients with serial FC measurement reports. Results: The mean age of the participants was 48.8 years. The final diagnosis of Itbc was confirmed in 30 patients based on complete mucosal healing on follow-up colonoscopy performed after 2 months of TATT. Before starting TATT, the mean FC level of the Itbc patients was 170.2 μg/g (range, 11.5-646.5). It dropped to 25.4 μg/g (range, 11.5-75.3) and then 23.3 μg/g (range, 11.5-172.2) after one and two months of TATT, respectively. The difference in mean FC before and one month after TATT was statistically significant (p<0.001), and FC levels decreased to below 100 μg/g in all patients after one month of TATT. Conclusions All Itbc patients showed FC decline after only 1 month of TATT, and this finding correlated with complete mucosal healing in the follow-up colonoscopy after 2 months of TATT.
