Adenomyotic cyst is very rare disease, their sizes are mostly lesser 5mm. The intrauterine adenomyotic cyst may arise from progressive expansion of cyst due to progressive menstrual bleeding. Authors experienced a case of large adenomyotic cyst within myometrium occuring in a l9-year-old woman, and who was accompanied with endometriosis. The cyst was about 3 x 3em sized, and had chocolate colored thick viscous contents, We experienced one case of adenomyotic cyst which was thought to be degenerated uterine myoma, so we report the case with a brief review of the concerned literatures.

PURPOSE: The purpose of this study was to evaluate the diagnostic accuracy of [18F]FDG PET in the diagnosis of recurrent head and neck cancer after the completion of surgery and radiotherapy in patients with head and neck cancers. MATERIALS AND METHODS: In fifty-nine patients with head and neck cancers, whole body [18F]FDG PET studies were performed. According to the different therapeutic modalities, patients were divided into four groups (Group I; pre-treatment, Group II; surgery, Group III; radiotherapy, Group IV; both surgery and radiotherapy). [18F]FDG PET images were compared with clinical, CT and histopathologic findings. RESULTS: For detection of metastatic lymph nodes in 14 patients of pre-treatment group (group I), the sensitivity and specificity of PET were 100% (10/10) and 75% (3/4), and those of CT were 80% (8/10) and 100% (4/4). For detection of recurrence in 45 patients of post-treatment group, overall sensitivity and specificity of PET were 96.2% (25/26) and 78.9% (15/19) [(100% and 75% in group II, 80% and 50% in group III, and 100% and 100% in group IV)] without significant difference from pre-treatment group (p>0.1). In detecting recurrence, the sensitivity and specificity of [18F]FDG PET were 90.9% (10/11) and 20% (1/5) in 16 patients who underwent [18F]FDG PET within 2 months after the completion of treatment. The specificity of these patients was significantly lower than that of 29 patients (100% of sensitivity and specificity) who underwent [18F]FDG PET 2 months after treatment (p<0.05). CONCLUSION: [18F]FDG PET is an accurate diagnostic modality for the detection of recurrence in head and neck cancer. Post-therapy [18F]FDG PET should be obtained at least 2 months after the completion of surgery or radiotherapy.

BACKGROUND AND OBJECTIVES: The simultaneous binaural bithermal caloric test is performed by stimulating both ear canals with the water of same temperature at the same time. There are some reports that the simultaneous binaural bithermal caloric test appears to be more sensitive than the alternative bithermal caloric test in detecting caloric vestibular abnormalities. However, it is not well known yet what effect simultaneous binaural bithermal caloric test has on the vestibulo-ocular reflex. We attempted to verify the clinical usefulness of the simultaneous binaural bithermal caloric test. MATERIALS AND METHODS: Otoneurologically normal subjects (n=20) and patients who have complaints of dizziness (n=141) were tested. The regular bithermal caloric test was performed, using Life-Tech water irrigator and the water of temperatures 30degreesC and 44degreesC. The simultaneous binaural bithermal test was performed using Brooker-Grams closed loop irrigator with 27degreesC and 44degreesC water. The irrigation time was 40 seconds and nystagmus was detected for more than 120 seconds by electronystagmography. We divided the test response into six types with the reference value of canal paresis (CP) of the regular bithermal caloric test. RESULTS: The distribution of nystagmus type did not show regular pattern in the normal controls. The distribution of type I and II was 77.4% when CP was more than 25% in patients, 50.6% when CP was less than 25% in patients, and 42.5% in the normal group. The maximal velocity of slow component increased in the unilateral canal paresis patients (CP>25%), compared with the normal controls and no unilateral canal paresis patients (Cp<0.05). CONCLUSION: We observed that the simultaneous binaural bithermal caloric test has advantages of being less time-consuming and more comfortable. When the maximal velocity of slow component is more than 22.6 deg/sec with type I or II response, we could predict canal paresis; however, further studies should be made for abnormal response of simultaneous caloric response on the central nervous ststem.

Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

PURPOSE: Many investigators suggested that changes in hormonal environment in the postmenopausal women functionally or histologically effect the clitoris and vagina. We investigated the mechanism of female se xual dysfunction occurring in the decreased hormonal status, and aimed to establish and experimental base for the hormone replacement in postmenopausal women to correct sexual dysfunction. MATERIALS AND METHODS: Twenty mature female New Zealand white rabbits were randomly divided into three groups; control group, oophorectomy group, estrogen replacement group after oophorectomy. Nitric oxide synthase (NOS) activity and the degree of expression of neuronal NOS (nNOS) and endothelial NOS (eNOS), collagen content in clitoral tissues were analysed. RESULTS: nNOS and eNOS were significantly increased in the oohporectomized group while decreased in the estrogen replacement group (p<0.01). NOS activity showed the similar pattern of change (p<0.05). Oophorectomy induced a significant increase in collagen content, while the ratio of smooth muscle content was increased significantly after the estrogen replacement (p<0.01). CONCLUSIONS: Estrogen deficiency induces collagen synthesis and decreases the content of smooth muscle in clitoris, resulting in a structural relaxation difficulty. We believe that NOS becomes more active to improve the relaxation difficulty and that hormone replacement helps to restore the normal state of smooth muscle relaxation. Considering these findings, we suggest that estrogen down-regulates NOS and its activity.

OBJECTIVE: Taxol (paclitaxel)-induced apoptosis was studied to understand their biological mechanism correlated with the expression of p53 in the SKOV-3 and OVCAR-3 ovarian cancer cell lines. MATERIALS AND METHODS: The SKOV-3 and OVCAR-3 cell lines were cultured in RPMI 1640 medium without taxol (control group) and with taxol for 24 h and 48 h (experimental group). After harvest, the cells were stained with annexin V-FITC (fluorescein isothiocyanate) and anti-cytokeratin antibodies (clone CAM5.2 and clone MNF116). They were washed and stained with p53 antibody. After then the secondary antibodies, i.e., FITC- or phycoerythrin (PE)-conjugated goat anti-mouse (GAM) immunoglobulin G (GAM IgG-FITC or GAM IgG-PE) were added in the cells and they were incubated in the dark. DNA of these cells were stained sequentially with propidium iodide (PI). Standard FACScan equipped with a 488 nm single laser was used for the analysis of these cells. RESULTS: Both of SKOV-3 and OVCAR-3 cell lines were arrested in the G2M phase after treatment of taxol, suggesting that these cells would eventually enter into the stage of cell death. Fractions of negative cytokeratin and positive annexin V and amount of sub-G0G1 fraction indicative of apototic fractions were lower in the SKOV-3 cell line compared with that in OVCAR-3 cell line, probably as a result of lower sensitivity of SKOV-3 cell line to the taxol. p53 expression were not detected in SKOV-3 cell line. On the basis of observed findings in SKOV-3 cell line and findings of high expressions of p53 regardless of taxol treatment, no increases in their expressions according to culturing time, and gradual increases in sub-G0G1 fractions and in fractions of negative cytokeratin and positive annexin V indicative of apoptosis in OVCAR-3 cell line, we concluded that the expression of p53 would not be associated with cell cycle changes and the arrest in the G2M pahse but associated with the appearance of apotosis. CONCLUSION: Our results suggest that flow cytometric detection of the apoptotic fractions would be an effective, fast, and accurate method for the chemosensitivity test in tumor cells before the administration of anti-cancer drugs in gynecologic cancer patients.

OBJECTIVE: Previous studies have suggested that hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR C677T) mutations are associated with increased risk of recurrent spontaneous abortion (RSA). Recently, a second site polymorphism in MTHFR, 1298A-->C, which changes a glutamic acid into an alanine residue, was shown to be associated with a decreased enzyme activity. We tested whether the variant alleles of MTHFR C677T and A1298C are risk factor (biomarker) for RSA. MATERIALS AND METHODS: We analyzed DNA from a case-control study in the Korean DNA was extracted from blood samples of 118 patients with RSA and 123 healthy fertile patients as the controls. MTHFR variant alleles were determined by a PCR-restriction fragment length polymorphism assay. RESULTS: We found no evidence for an association between 677TT genotype and risk of RSA (OR=1.95, 95% CI=0.84~4.50, p=0.12). However, the MTHFR 1298AC (OR=0.36, 95% CI=0.20~ 0.63, p=0.0004) and 1298AC+CC (OR=0.35, 95% CI=0.20~0.61, p=0.0002) genotypes were lower among 118 RSA cases compared with 123 controls, conferring a 2.8-fold decrease in risk of RSA, respectively. Moreover, the combined genotypes of MTHFR 677CC/1298AC (OR=0.30, 95% CI= 0.10~0.88, p=0.029) and 677CT/1298AC (OR=0.77, 95% CI=0.60~0.99, p=0.043) also showed significantly lower risk than those with MTHFR 677CC/1298AA type. CONCLUSION: MTHFR 1298AC, MTHFR 677CC/1298AC and 677CT/1298AC genotypes may represent genetic markers for the protection of RSA at least in Korean women.

For over a half centry, physicians have suspected that patients with duodenal ulcer are offered an insurance policy against gastric carcinoma. This may be used clinically so that gastric lesion in the presence of duodenal ulcer, are considered benign. However, the duodenal ulcer may coexit with gastric cancer, Although rare in incidence of coexistence of duodenal ulcer and gastric cancer, physician always should be alert in diagnosing of gastric lesion in the presence of the duodenal ulcer. Here, we present 60 years old woman with coexitence of duodenal ulcer and gastric cancer, diagnosed by endoscopy and treated surgically.
