Endometriosis generally occurs in the pelvis, particularly in the broad ligament, round ligament, ovaries, fallopian tubes or uterosacral ligament. However, many unusual sites have been described, including the umbilicus, cesarean section scars, hernia sacs, appendix, vagina, vulva, omentum and perineum. We experienced a case of perineal endometriosis diagnosed according to cyclic perineal pain associated with menstration and report it with brief review of literature.

The thymus is a central lymphoid organ for T cell development. Thymic epithelial cells (TECs) constitute a major component of the thymic stroma, which provides a specialized microenvironment for survival, proliferation, and differentiation of immature T cells. In this study, subsets of TECs were examined immunohistochemically to investigate their cytokeratin (CK) expression patterns during thymus regeneration following thymic involution induced by cyclophosphamide treatment. The results demonstrated that both normal and regenerating mouse thymuses showed a similar CK expression pattern. The major medullary TECs (mTEC) subset, which is stellate in appearance, exhibited CK5 and CK14 staining, and the minor mTEC subset, which is globular in appearance, exhibited CK8 staining, whereas the vast majority of cortical TECs (cTECs) expressed CK8 during thymus regeneration. Remarkably, the levels of CK5 and CK14 expression were enhanced in mTECs, and CK8 expression was upregulated in cTECs during mouse thymus regeneration after cyclophosphamide-induced acute thymic involution. Of special interest, a relatively high number of CK5+CK8+ TEC progenitors occurred in the thymic cortex during thymus regeneration. Taken together, these findings shed more light on the role of CK5, CK8, and CK14 in the physiology of TECs during mouse thymus regeneration, and on the characterization of TEC progenitors for restoration of the epithelial network and for concomitant regeneration of the adult thymus.

PURPOSE: The anticancer property and cytoprotective role of selenium in chemotherapy have been reported. However, the combination effects of selenium on chemotherapy for advanced breast cancer have not yet been clearly defined. The purpose of this study was to investigate the combined effects of selenium on chemotherapy using docetaxel on breast cancer cell lines. METHODS: Under adherent culture conditions, two breast cancer cell lines, MDA-MB-231 and MCF-7, were treated with docetaxel at 500pM and selenium at 100nM, 1microM, or 10microM. Changes in cell growth, cell cycle duration, and degree of apoptosis after 72 hours in each treated group were evaluated. RESULTS: In the MDA-MB-231 cells, the combination therapy group (docetaxel at 500pM plus selenium at 10microM) showed a significantly decreased percentage of cell growth (15% vs. 28%; P = 0.004), a significantly increased percentage of late apoptosis (63% vs. 26%; P = 0.001), and an increased cell cycle arrest in the G2/M phase (P = 0.001) compared with the solitary docetaxel therapy group. Isobologram analysis demonstrated the synergistic effect of the combination therapy in the MDA-MB-231 cells. However, in the MCF-7 cells, no significant differences in the percentage of cell growth apoptosis, the percentage of apoptosis, and the pattern of cell cycle arrest were noted between the combination therapy groups and the solitary docetaxel therapy group. CONCLUSION: Our in vitro study indicated that the combination of selenium with docetaxel inhibits cell proliferation through apoptosis and cell arrest in the G2/M phase in MDA-MB-231 breast cancer cells.

Dry mouth is a common symptom in over middle- aged women. Xerostomia itself can be caused by multifactorial etiolgy. Dry mouth may occur with the use of medications, as a complication of connective tissue and autoimmune disease, such as Sjogren's syndrome or sicca syndrome, with radiation therapy to the head and neck or diabetes mellitus, or with a number of other condition. Even stress and anxiety can lead to a dry mouth. Also, Abnormal liver function is associated with drugs, viral infection, alcohol, obesity, autoimmne disease and a number of other disease. A 41-year-old women complaining of xerostomia and known abnormal liver fuction since 1 year was admitted to our medical examination center. In this case, Final diagnosis was systemic lupus erythematosus with autoimmune hepatitis and secondary Sjogren's syndrome through characteristic clinical finding, liver biopsy, positive Schirmer's test, salivary gland biopsy, and salivary scintigraphy. The various immunosuppresant medication has taken and then liver function indices and clinical symptoms were improved.

PURPOSE: To compare the diagnostic efficacy of fast spin-echo (FSE) T2-weighted MR imaging with and without fat suppression. MATERIALS AND METHODS: Twelve patients (7 men and 5 women; mean age, 48 years) with pathologically proven cancer of the tongue were included in this study. In all of these, FSE T2-weighted MR images with and without fat suppression were obtained in the same imaging planes before surgery or biopsy. Two radiologists visually compared the images thus obtained in terms of detection, extent, and conspicuity of the tumor, and the contrast-to-noise ratio (CNR) of each tumor was also calculated. RESULTS: In all patients, both imaging modalities were equal in terms of tumor detection. In 4 of 12(33%), the extent of the tumor was greater with fat suppression, while in eight (67%), it was almost the same both with and without. In ten patients (83%), the tumor was more conspicuous with fat suppression, and percentage CNRs were significantly higher with fat suppression than without (180 +/-70% and 113 +/-61%, respectively; p = 0.02). CONCLUSION: For the evaluation of patients with tongue cancer, fat-suppressed FSE T2-weighted MR imaging is superior to its conventional equivalent.

BACKGROUND: The purpose of this study was to investigate the prevalence of rhabdomyolysis and its association with both clinical course and prognosis and to evaluate the factors associated with rhabdomyolysis in patients with hyperglycemic emergencies. METHODS: We reviewed the medical records of patients with hyperglycemic emergencies who visited our hospital from May 2003 to April 2010. We assessed the clinical characteristics, biochemical profiles and clinical course of patients and analyzed these data according to the presence of rhabdomyolysis. RESULTS: The prevalence of rhabdomyolysis was 29 patients (28.4%) among 102 patients. Mean serum osmolarity, glucose and serum creatinine levels were higher in patients with rhabdomyolysis than those without rhabdomyolysis. Patients with rhabdomyolysis had higher rates of hemodialysis and mortality than those without the condition. The factors associated with rhabdomyolysis in the hyperglycemic emergency state were increased serum osmolarity and APACHE II score on admission (P < 0.05). CONCLUSION: Rhabdomyolysis commonly occurred in patients with hyperglycemic emergencies and this could aggravate their clinical course and increase mortality.

OBJECTIVE: The aim of this study was to evaluate the relation between the chromosomal translocation and the outcome of pregnancy. METHODS: Between 1989 and 2001, 26 translocation carriers have been detected in our center and Jin Obstetrics and Gynecology Clinic. The subjects consisted of 26 couples that included 14 reciprocal translocation carriers and 12 Robertsonian translocation carriers. The balanced translocation carriers were analyzed retrospectively. RESULTS: The most frequent indication for parental chromosomal examination was repeated abortions or fetal death(57.7%). In contrast to couples with reciprocal translocations, a high excess of female over male carriers was found in the group of Robertsonian translocations. The rates of miscarriages (68.0%) in prior pregnancies were significantly higher than the birth rates of morphologically normal newborns(16.0%). Prenatal chromosomal examination in subsequent pregnancies revealed that 24.0% of the fetuses showed normal karyotypes, 56.0% of the fetuses showed balanced translocations and 20.0% of the fetuses showed a chromosomal imbalance. The unbalanced karyotypes consisted of three trisomies, one partial trisomy and one duplication. There was no case of partial monosomy in this study. CONCLUSIONS: The risk of unbalanced chromosome abnormalities was greater in our study than the empirically known risk. Prenatal examination is always indicated in carriers of any type of translocation.
