OBJECT: In order to estimate the frequency and risk factors for adenomyosis. METHOD: The clinical records of 1127 women undergoing hysterectomy were retrieved in the Department of Obstetrics and Gynecology, Incheon Christian Hospital, during 7 years, from Jan. 1st 1991 to Dec. 31st 1997. RESULT: The following results were obtained. 1. Adenomyosis was found in 206 of 1127 patients(18.3%). 2. The highest incidence was 41-50 years of age group, an incidence of 55% and mean age group was 46.9 years. 3. Adenomyosis was more frequently observed in parous woman than non-parous woman, such as 8.3% and 91.7%, respectively. 4. Grossly, the size of uterus was enlarged more than 10 weeks gestational size in adenomyosis, an incidence of 62.4%. 5. Pelvic pain, dysmenorrhea and metrorrhagia were common symptom of adenomyosis, an incidence of 26.7%, 25.2% and 19.4%, respectively. 6. Myoma was the most combined disease in adenomyosis, showing the incidence of 53.4%. 7. Combined pelvic endometriosis was not observed in this study. 8. Endometrial findings of adenomyosis showed proliferative phase of normal endometrial cycle in the highest incidence, giving 72.3% of all cases. 9. Preoperative diagnostic accurracy of adenomyosis was 8.2%. CONCLUSION: This results show that deeply understanding of the common symptom and epidemiology of adenomyosis improve the preoperative diagnostic accuracy.

PURPOSE: To analyze the gene expression profiles of uterine cervical cancer, and its variation after radiation therapy, with or without concurrent chemotherapy, using a cDNA microarray. MATERIALS AND METHODS: Sixteen patients, 8 with squamous cell carcinomas of the uterine cervix, who were treated with radiation alone, and the other 8 treated with concurrent chemo-radiation, were included in the study. Before the starting of the treatment, tumor biopsies were carried out, and the second time biopsies were performed after a radiation dose of 16.2~27 Gy. Three normal cervix tissues were used as a control group. The microarray experiments were performed with 5 groups of the total RNAs extracted individually and then admixed as control, pre-radiation therapy alone, during-radiation therapy alone, pre-chemoradiation therapy, and during-chemoradiation therapy. The 33P-labeled cDNAs were synthesized from the total RNAs of each group, by reverse transcription, and then they were hybridized to the cDNA microarray membrane. The gene expression of each microarrays was captured by the intensity of each spot produced by the radioactive isotopes. The pixels per spot were counted with an Arrayguage(R), and were exported to Microsoft Excel(R). The data were normalized by the Z transformation, and the comparisons were performed on the Z-ratio values calculated. RESULTS: The expressions of 15 genes, including integrin linked kinase (ILK), CDC28 protein kinase 2, Spry 2, and ERK 3, were increased with the Z-ratio values of over 2.0 for the cervix cancer tissues compared to those for the normal controls. Those genes were involved in cell growth and proliferation, cell cycle control, or signal transduction. The expressions of the other 6 genes, including G protein coupled receptor kinase 6, were decreased with the Z-ratio values of below -2.0. After the radiation therapy, most of the genes, with a previously increase expressions, represented the decreased expression profiles, and the genes, with the Z-ratio values of over 2.0, were cyclic nucleotide gated channel and 3 Expressed sequence tags (EST). In the concurrent chemo-radiation group, the genes involved in cell growth and proliferation, cell cycle control, and signal transduction were shown to have increased expressions compared to the radiation therapy alone group. The expressions of genes involved in angiogenesis (angiopoietin-2), immune reactions (formyl peptide receptor-like 1), and DNA repair (cAMP phosphodiesterase) were increased, however, the expression of gene involved in apoptosis (death associated protein kinase) was decreased. CONCLUSION: The different kinds of genes involved in the development and progression of cervical cancer were identified with the cDNA microarray, and the proposed theory is that the proliferation signal starts with ILK, and is amplified with Spry 2 and MAPK signaling, and the cellular mitoses are increased with the increased expression of Cdc 2 and cell division kinases. After the radiation therapy, the expression profiles demonstrated the evidence of the decreased cancer cell proliferation. There was no significant difference in the morphological findings of cell death between the radiation therapy alone and the chemo-radiation groups in the second time biopsy specimen, however, the gene expression profiles were markedly different, and the mechanism at the molecular level needs further study.

We evaluated the urological complications in 200 renal transplantations performed in the Department of Urology, Catholic Medical College between March 1969 and April 1986. The following results were obtained; 1. Of 200 cases of recipient 151 cases were male and 49 cases were female. 2. The ureteroneocystostomy was performed as the method of modified Politano-Leadbetter (intravesical approach) in 66 cases and modified Mackinnon (extravesical approach) in 134 cases. 3. Our incidence of urological complications in 200 renal transplantations was 7%1l4 cases). Postoperative complications developed in Il of the 66(l6.7%) who underwent intravesical ureteroneocystostomy and 3 of the 134(2.2%) who underwent extravesical ureteroneocystomy. 4. The details of the complications were as follows: 6 were ureteral obstruction, 5 ureteral leakage, 2 urine leakage from anastomosis site and 1 was bleeding from anastomosis site. 5. Operative method for urological complications were ureteroureterostomy (10) in ureteral obstruction(6) and ureteral leakage (4), ureteroneocystostomy (1) in ureteral leakage, simple suture (2) in bleeding(1) and urine leakage from anastomosis site(2).

OBJECTIVE: Human embryonic stem cell derived from blastocyst randomly differentiates into multiple cell types during embryoid body development. Bone morphogenetic proteins (BMPs) are members of the transforming growth factor type beta superfamily. We have a question whether BMP2 and/or BMP4 can induce trophoblast specific genes in human ES cells using SNU hES3 cell line. METHODS: Human embryonic stem cell line (SNU hES3) was supplied by Miz Medi Hospital Seoul National University. Cultured hES cells were divided into small clumps and then allow for EB formation in differentiation medium. After EB formation, EBs were transferred onto gelatin coated dishes and given hES conditioned medium alone (control) or supplemented as following treatment for 6 days; rhBMP4 100 ng/mL; rhBMP2 100 ng/mL; BMP4 100 ng/mL +BMP2 100 ng/mL. RT PCR was performed for trophoblast specific genes. During culture, supernatant was collected and measured for estradiol (E2), progesterone, and hCG beta by enzymeimmuno assay (EIA) kit. RESULTS: BMP4 and BMP2 increase chorionic gonadotropin beta (hCG beta), glical cell missing 1 (GMC1), and CD9 as trophoblast specific gene markers confirmed by RT PCR. However, the non classical HLA class I molecule HLAG1, was not expressed in our studies. And we cannot find significant differences of the level of estradiol, hCG nd progesterone in this study. CONCLUSION: The results suggest that BMP 4 and 2 have an additive effect on induction of trophoblast related genes in SNU hES3 cell line. Although we failed to induce the differentiation of human ES cells to trophoblast, this study could provide the possibility for the differentiation of early human trophoblast cells and thus need further studies.

PURPOSE: To report a case of corneal ulcer due to Alcaligenes faecalis in a patient with a preexisting corneal ulcer. CASE SUMMARY: A 58-year-old male patient presented with a corneal ulcer without a history of any trauma. The patient had a history of corneal ulcer 9 months earlier. The patient had previously been diagnosed with diabetic retinopathy and neovascular glaucoma, and his visual acuity was no light perception. Corneal scraping and culture yielded Alcaligenes faecalis susceptible to most antibiotics in the antibiotic susceptibility test. After treatment with empirical systemic antibiotics and eyedrops, his eye improved with a remaining corneal scar. CONCLUSIONS: Alcaligenes faecalis should be considered as a causal pathogen of corneal ulcer in patients with suspicious compromised ocular surface, such as previous corneal ulcer.

A sialocele is a subcutaneous cavity containing saliva, most often caused by facial trauma or iatrogenic complications. In subcondylar fractures, most surgeons are conscious of facial nerve injury; however, they usually pay little attention to the parotid duct injury. We report the case of a 41-year-old man with a sialocele, approximately 5×3 cm in size, which developed 1 week after subcondylar fracture reduction. The sialocele became progressively enlarged despite conservative management. Computed tomography showed a thin-walled cyst between the body and tail of the parotid gland. Fluid leakage outside the cyst was noted where the skin was thin. Sialography showed a cutting edge of the inferior interlobular major duct before forming the common major duct that seemed to be injured during the subcondylar fracture reduction process. We decided on prompt surgical treatment, and the sialocele was completely excised. A duct from the parotid tail, secreting salivary secretion into the cyst, was ligated. Botulinum toxin was administrated to block the salivary secretion and preventing recurrence. Treatment was successful. In addition, we found that parotid major ducts are enveloped by the deep lobe and extensive dissection during the subcondylar fracture reduction may cause parotid major duct injury.

Background: This study compares the difference in the clinical and radiologic outcomes when minimally invasive plate osteosynthesis (MIPO) technique is performed with or without using a positional screw in the treatment of humeral shaft fractures. Methods: From January 2010 to January 2021, a retrospective study was conducted on a total of 63 patients who underwent the MIPO technique for the treatment of humeral shaft fractures. We divided these patients into 2 groups: in group I, patients underwent MIPO without a positional screw; in group II, patients underwent MIPO with a positional screw. We compared functional outcomes including the American Shoulder and Elbow Surgeons score, University of California at Los Angeles score, Simple Shoulder Test, range of motion before and after surgery, operation time, blood loss, and complications. And we compared radiologic outcomes including pre- and postoperative anteroposterior (AP) and lateral displacement of the fracture and union time on plain radiographs. Results: The average patient age was 64.6 ± 15.1 years (range, 25–88 years). Group I consisted of 30 patients (10 men and 20 women), and group II consisted of 33 patients (11 men and 22 women). Between the 2 groups, there was no statistically significant difference in sex, body mass index, functional scores, AP and lateral displacement of the fracture on postoperative x-ray, operation time, and blood loss. In group II, a faster bony union was obtained than that in group I (4.6 vs. 6.4 months). Complications included 2 cases of transient radial nerve palsy in both groups and metallic failures (2 in group I and 1 in group II). Conclusions When performing MIPO for humeral shaft fractures, adding a positional screw could be more stabilizing than bridge plating without a positional screw, leading to faster bony union. A positional screw might help control interfragmentary movement without inhibiting essential interfragmentary movement for fracture healing.
