Steroid cell tumors, not otherwise specified, are infrequently encountered ovarian neoplasms, which constitute <0.1% of all ovarian tumors. Most of these tumors are unilateral, and almost one-third of all cases are reportedly malignant. However, because most of these tumors are diagnosed in the early stage, and do not recur or metastasize, little is known about their response to therapies such as chemotherapy or radiation. Here, we present a rare case of recurrent steroid cell tumor, not otherwise specified that showed a complete response after debulking surgery, radiofrequency ablation, and adjuvant chemotherapy.

Microinvasive adenocarcinoma is not as well studied as microinvasive squamous cell carcinoma because diagnosis of adenocarcinoma cannot be ascertained for early invasive lesions. However, most clinicians consider a depth of invasion of 3 mm without lympho-vascular space invasion as the maximum limit for conservative management. Microinvasive cervical adenocarcinoma is characterized by a rare incidence of lymph node metastasis and very good prognosis. We describe a 62-year-old patient with an extremely early cervical adenocarcinoma which was detected only by endocervical curettage. However, she had multiple macroscopic pelvic node metastases. Clinicians should consider the probability of lymph node metastasis, although management of stage IA1 cervical adenocarcinoma may still be conservative.

Baicalin is flavonoid and major component of PC-SPES. Flavonoids including baicalin have been reported to not only function as anti-oxidant but also cause cytotoxic effect. Baicalin hydrate has been reported to induce cell death, however the mechanism by which baicalin hydrate induces the apoptosis of cancer cells is still unclear. To evaluate the mechanistic insights of apoptosis by baicalin hydrate, we tested the activities of apoptosis signaling pathway in HeLa cells. The viability of HeLa and HeLa s3 cells was markedly decreased by baicalin hydrate in a dose- and time- dependent method. Baicalin hydrate induced the apoptotic death of HeLa cells, which was characterized by the chromatin condensation of the nuclei and phosphorylation of histone H2AX. Baicalin hydrate increased the sub-G1 DNA content of HeLa cell lines. Baicalin hydrate digested Bid protein, increased Bak protein level and also, induced mitochondrial dysfunction disrupted as shown as the mitochondrial membrane potential. It activated caspase-3, thereby resulted in cleavage of poly (ADP) ribose polymerase (PARP).

Steroid cell tumors, not otherwise specified (NOS), are infrequently encountered ovarian neoplasms. They constitute <0.1% of all ovarian tumors. They usually occur in younger individuals (mean age, 43 years) and, in contrast to other steroid cell tumors, occasionally occur before puberty. The majority of these tumors produce steroids with testosterone being the most common. Various virilizing symptoms such as hirsutism, temporal baldness, and amenorrhea are common in these patients; however massive ascites is an infrequent symptom. We report a case of steroid cell tumor, not otherwise specified, with hypertension, obesity, ascites and elevated CA 125 with brief review of literature.

OBJECTIVE: To understand the difference of defecation physiology between postpartum and postoperative women. METHODS: Between July 1998 to April 1999, we performed defecogram and pudendal nerve motor latency to 31 women, who were 8 postoperative women, 9 post cesarean-section state women, and 14 normal vaginal delivery-state women. RESULTS: According to the defecogram results, only squeezing angles of the anorectal angle were significantly increased(96.0 vs 72.3, 74.9 degree) in normal vaginal delivery-state women compared to post cesarean-section state and postoperative women, but rest and evacuation angles were not. And to pudendal nerve latency, there were no statistically significant difference. CONCLUSION: We concluded that the pudendal plexus was damaged during labor, therefore its ability to control puborectalis muscle was damaged. So, the anorectal angles of squeezing of postpartum women were significantly increased, compared to those of post cesarean section women or postoperative women.

Primary transitional cell carcinoma of the ovary is recently recognized, as one of the main types of ovarian carcinoma. Histologically, it is distinguished from malignant Brenner tumor only in the abscence of benign or proliferative Brenner tumor component. primary transitional cell carcinomas are more aggressive than malignant Brenner tumors. However, Primary transitional cell carcinomas have a better response to chemotherapy than other types of ovarian carcinomas. We report a case of primary transitional cell carcinoma presenting as both ovarian masses that developed in a 60-year-old woman with a brief review of literature.

BACKGROUND: Umbilical cord (UC) is a promising source of mesenchymal stromal cells (MSCs). We compared the characteristics of MSCs from cryopreserved UC with those from fresh tissues, and demonstrated the possibility of UC cryopreservation for acquisition of MSCs from cryopreserved UC. METHODS: Each UC was sliced into two types (1~2 mm3 vs. 0.5 cm), and cryopreserved in liquid nitrogen using different media (autologous cord blood plasma, aCBP vs. RPMI 1640). A fresh aliquot of 1~2 mm3-sized UC was used as control tissue. After one week, the cryopreserved tissues were thawed and cultured. For the 0.5 cm UC, a slicing step into 1~2 mm3 was needed. Cell count, viability, proliferative activity, and surface antigens were determined from harvested MSCs. Several growth factors (EGF, IGF-1, PDGF, TGF-beta, bFGF, and VEGF), were measured from the culture supernatant. RESULTS: Eleven UC were enrolled in the study. Efficiencies of obtaining MSCs were higher in cryopreserved UC using RPMI 1640, compared with use of aCBP; the same result was observed for 0.5 cm sized UC, compared with 1~2 mm3 sized UC. No difference in proliferative activity was observed between MSCs from fresh and cryopreserved UC. The amount of growth factors in culture supernatant using RPMI 1640 was larger than that of fresh tissues. CONCLUSION: We obtained growth factors from the supernatant as well as MSCs from cryopreserved UC. As with a cord blood bank, in the future, cryopreservation of UC for acquisition of both MSCs and growth factors would be possible in a time of need.

BACKGROUND: Although cord blood (CB) is a well-known source of hematopoietic stem cells, uncertainties exist regarding the quality of cryopreserved CB. We investigated the changes in quality of CB units according to the duration of cryopreservation. METHODS: We analyzed CB units that were rejected from the Seoul Metropolitan Government Public Cord Blood Bank inventory after conventional processing, because of unsuitability for allogeneic transplantation. Two hundred CB units that were cryopreserved from 1 year to 5 years were selected. After thawing the cryopreserved CB units, the total nucleated cell (TNC) count, CD34+ cell count, number of colony-forming units (CFU), aldehyde dehydrogenase (ALDH) level, cell viability, and apoptosis were analyzed. We conducted a comparative analysis to identify the presence of statistically significant differences in the recovery rates of the TNC and CD34+ cell counts and to compare the results of ALDH level, the cell viability test, the apoptosis test, and CFU analysis among groups according to the duration of cryopreservation. RESULTS: The recovery rates of the TNC count, the CD34+ cell count, and cell viability did not differ significantly according to the duration of cryopreservation. ALDH analysis, the cell viability test, and the apoptosis test did not reveal any increasing or decreasing trend according to the duration of cryopreservation. Further, the numbers of CFU-granulocyte/macrophage and CFU-granulocyte/erythrocyte/macrophage/megakaryocyte did not differ significantly according to the duration of cryopreservation. CONCLUSION: These results suggest that the quality of CB is not affected by cryopreservation for up to a period of 5 years.

OBJECTIVES: To investigate the number of leiomyoma patients-exposed to bisphenol A (BPA) and to observe whether the serum concentration of BPA is related to leiomyoma growth. METHODS: A total of 158 patients were recruited for this study. Leiomyoma patients were divided into three groups, mild (n = 48), moderate (n = 32) and severe (n = 28), according to the size of leiomyomas. The control (n = 30) group was defined as having no leiomyomas. Transvaginal ultrasonography was used to identify and measure the leiomyomas. Serum BPA concentrations were measured by enzyme-linked immunosorbent assay. RESULTS: BPA was detected in 87.0% out of a total of 158 samples, and in 86.0% out of 108 leiomyoma patients. In detail, the detection rates of serum BPA were 88.0% in the control group, 77.2% in the mild group, 90.0% in the moderate group and 96.0% in the severe group. The mean BPA concentration in the control group was 0.558 +/- 0.097 ng/mL, the leiomyoma groups, the mean BPA concentrations were 0.274 +/- 0.063 ng/mL (mild), 0.346 +/- 0.064 ng/mL (moderate) and 0.647 +/- 0.039 ng/mL (severe) (P = 0.0003). Values represent the mean +/- standard error. CONCLUSION: The detection rates of serum BPA in the control and leiomyoma groups were 88.0% and 86.0%, respectively. However, there was no significant difference in the serum BPA concentrations between the control and leiomyoma groups. To verify the effect of BPA on leiomyoma growth, a close and sequential monitoring is recommended for people who are at risk for uterine leiomyoma.

Adverse drug reactions can cause considerable discomfort. They can be life-threatening in severe cases, requiring or prolonging hospitalization, impeding proper treatment, and increasing treatment costs considerably. Although the incidence of severe cutaneous adverse reactions (SCARs) is low, they can be serious, have permanent sequelae, or lead to death. A recent pharmacogenomic study confirmed that genetic factors can predispose an individual to SCARs. Genetic markers enable not only elucidation of the pathogenesis of SCARs, but also screening of susceptible subjects. The human leukocyte antigen (HLA) genotypes associated with SCARs include HLA-B*57:01 for abacavir (Caucasians), HLA-B*58:01 for allopurinol (Asians), HLA-B*15:02 (Han Chinese) and HLA-A*31:01 (Europeans and Koreans) for carbamazepine, HLA-B*59:01 for methazolamide (Koreans and Japanese), and HLA-B*13:01 for dapsone (Asians). Therefore, prescreening genetic testing could prevent severe drug hypersensitivity reactions. Large-scale epidemiologic studies are required to demonstrate the usefulness and cost-effectiveness of screening tests because their efficacy is affected by the genetic differences among ethnicities.
