ABSTRACT

PURPOSE OF INVESTIGATION: This study aimed to estimate the effectiveness of hysteroscopic myomectomy for symptomatic submucous uterine fibroids and to identify prognostic factors for persistent or recurrent symptoms. MATERIALS AND METHODS: A total of 237 patients who underwent hysteroscopic myomectomy were divided into three groups according to the classification of the European Society for Gynaecological Endoscopy: Type 0 (n=116), Type I (n=97), and Type II (n=24). Medical records and videotape records of all patients were retrospectively reviewed. RESULTS: Improvement of symptoms was achieved in 100% of Types 0 and I, and 66.7% of Type II. The five-year cumulative symptom-free rates after hysteroscopic myomectomy were 96.7% ± 1.9%, 87.8% 6.7%, and 44.5% ± 12.7% in Types 0, I, and II, respectively. The mean symptom-free periods were 46.2 ± 2.6, 47.7 ± 2.7, and 24.7 ± 6.3 months in Types 0, I, and II, respectively. Logistic regression analysis showed that co-existence of other myomas and Type II were independent prognostic factors for recurrence of symptoms. CONCLUSION: Type I fibroids are a good indication for hysteroscopic myomectomy. In Type II, some patients feel that their symptoms improve, but this curative effect could be temporary.

ABSTRACT

The aim of this analysis was to investigate the onset time and significance of maximum volume of polyhydraminios and whether the tter was associated with causes. This was a retrospective cohort study between 2012 and 2014. A total number of 68 singleton pregancies were analyzed. Gestational age at onset of polyhydramnios was 30.0 ± 2.8 (25-36) weeks in maternal factor, 30.0 ± 3.5 (25- 7) weeks in fetal factor, and 32.3 ± 2.0 (27-37) weeks in idiopathic factor. Median of maximum amniotic fluid index (AFI) was gnificantly late onset in idiopathic factor. Diabetes, gestational or pre-existing, was present in all of women (ten cases) in maternal facror. Higher AFI was found to be associated with an increased frequency of prenatally detected congenital anomalies. Abnormal fetal kary- type noted in 18/45 (40%) cases of polyhydramnios. Polyhydramnios diagnosed on ultrasound requires further maternal and fetal iagnostic tests.

ABSTRACT

This was a retrospective cohort study between 2002 and 2011. A total number of 150 singleton pregnancies with preterm premature rupture of membranes (PROM) (before 34 weeks) were analyzed. Histological chorioamnionitis (Blanc grade III) was significantly increased over three days from onset of premature rupture of membranes. The positive relationship was strengthened (odds ratios, 3.5; 95% confidence intervals, 1.5-5.2) over three days from onset of preterm PROM. PROM is a risk factor important for histological chorioamnionitis. To avoid neonatal infection, early termination is recommended in preterm PROM patients.

ABSTRACT

Retroperitoneal leiomyosarcoma is a relatively rare and aggressive tumor. Because of its rarity, it is difficult to arrive at a definite diagnosis preoperatively and to design an effective strategy. Here the authors report a case of peritoneal leiomyosarcoma in which diagnosis was difficult because the clinical course resembled that of ovarian cancer. A 77-year-old woman diagnosed with ovarian cancer underwent laparotomy. The excised tumor contained a necrotic polypoid mass that histologically displayed the features of leiomyosarcoma. The patient received adjuvant chemotherapy with a combination of gemcitabine and docetaxel but died two months after surgery owing to the aggressive behavior of the tumor. Because the preoperative diagnosis in this case was ovarian cancer, arriving at a treatment strategy assuming peritoneal leiomyosarcoma was difficult. If complete surgical resection of tumor is not performed, as in the present case, the prognosis can be extremely poor.

ABSTRACT

The authors here report a 54-year-old (gravida 0, para 0), who claimed to have had her menarche at age 13 and menopause at 52 years. Two months prior to presentation, the subject first noticed a hard but elastic fist-sized mass in the left inguinal region that gradually grew, causing pressure-related pain. Although the external genitalia appeared female, the vagina was short and blind-ending, and no uterus or ovaries were identified on transvaginal ultrasound. Chromosome banding results (G-band method) showed 46XY. Laparoscopy revealed no traces of a vestigial uterus or ovaries; thus, based on the appearance of the external genitalia, a diagnosis of testicular feminization syndrome was made. Pathological testing of the palpable mass led to a diagnosis of seminoma with Leydig cell hyperplasia. Thus, in this case, the development of a seminoma in an undescended testis led to the detection of testicular feminization syndrome.

ABSTRACT

The present authors analyzed patients' backgrounds and pre-surgical findings to clarify the risk factors of rupture of fallopian tubal pregnancy. The surgical findings 113 cases were clearly diagnosed as fallopian tubal pregnancy with or without rupture. Twenty-six cases of fallopian tubal pregnancy were ruptured and 87 cases were not ruptured at the time of operation. The risk factors of fallopian tubal rupture were assessed by Chi-square for independence test and multiple regression analysis. Obesity (BMI over 26), prior birth history, social welfare entitlement, ultrasonography findings of fetal heart movement, and pre-surgical serum beta-hCG level more than 3,000 mIU/ml patient were significantly higher risk in fallopian tubal rupture. Fertility treatment patient were at significantly lower risk for fallopian tubal rupture. Higher beta-hCG levels, especially >3,000 mIU/ml is associated with increased risk of fallopian tubal rupture in ectopic pregnancy.

ABSTRACT

The anti-emetic effect and safety in patients receiving ondansetron hydrochloride (OND group) and ondansetron and dexamethasone (DEX group) concurrently in cases of acute and delayed onset emesis induced by a single high dose of cisplatin, given as a chemotherapy to gynecological cancer patients, were comparatively studied. The study subjects were 139 gynecological cancer patients. The OND group received 4 mg of ondansetron via slow intravenous injection on Day 1, 30 minutes prior to cisplatin, and for Days 2 to 5, the subjects orally received 4 mg ondansetron tablet each day. The DEX group received the same dose regimen of ondansetron as the OND group for Days 1-5, but in addition the subjects received dexamethasone injection in doses of 8 mg twice daily on Day 1 and 4 mg (1 mg QID) daily for Days 2-5. An anti-emetic effect against acute nausea and vomiting was achieved in 47.9% of the OND group and in a higher rate of 84.2% of the DEX group. Significantly better efficacy was seen in the DEX group also in the complete suppression rate of nausea and vomiting and the improvement of food intake. The group also achieved better efficacy in delayed onset of emesis. Adverse reactions were observed in 2 cases (2 reports of headache) in the OND group and 5 cases (2 reports of hiccups, 2 headache, 2 diarrhea, one constipation, one hot facial flushes and one elevation of gamma-GTP) in the DEX group; however, since the symptoms were all mild, we did not consider there was any problem in safety. We conclude from the above findings that concurrent administration of ondansetron hydrochloride and dexamethasone is a clinically useful treatment for acute and delayed onset emesis induced by a single high dose of cisplatin given to gynecological cancer patients.

ABSTRACT

BACKGROUND: This study was conducted to elucidate the prognostic significance of a three-grade system for lymphovascular space invasion (LVSI). METHODS: The prognostic significance of the grading of LVSI as compared with other pathologic variables was evaluated in a study of 303 Japanese women with endometrial carcinoma. The criteria for determining the grade of LVSI were as follows: none (no LVSI), mild (a focus of LVSI was recognized around a tumor), and severe (diffuse or multifocal LVSI were recognized around the tumor or in the myometrium regardless of the degree of myometrial invasion). Both univariate and multivariate regression analyses were performed. The effects of different surgical methods and adjuvant therapies on survival were also examined. RESULTS: A univariate survival analysis showed that survival significantly correlated with surgical stage, histologic grade, depth of myometrial invasion, LVSI, cervical invasion, ovarian metastasis, and tubal metastasis. Of the three grades of LVSI, survival showed the most difference between the mild and severe groups. In multivariate analysis, the highest correlation with survival was observed for LVSI (P = 0.0008). Lymph node metastasis was also significantly associated with LVSI (P = 0. 0001). The correlation between histologic variables and survival was only slightly influenced by the differences in surgical methods and adjuvant therapies. CONCLUSIONS: The grading of LVSI was found to be an important histologic prognostic variable. The severe degree of LVSI also was found to be a good indicator of lymph node metastasis. It is therefore important to evaluate the grade of LVSI based on a histologic examination of at least one cut surface of the hysterectomy specimen that macroscopically shows the deepest myometrial invasion.

ABSTRACT

Endometrial specimens of 34 (25 premenopausal and 9 postmenopausal) breast cancer patients receiving tamoxifen were immunohistochemically examined using estrogen receptor (ER), progesterone receptor (PR), Ki-67, and epidermal growth factor receptor (EGFR) antibodies. Proliferative (n = 6), secretory (n = 9), and postmenopausal (n = 6) endometria served as controls. The ER and PR expressions of the glandular cells in tamoxifen-treated patients did not differ from those of the glandular cells in the control women regardless of menopausal status. The Ki-67 index of glandular cells in tamoxifen-induced amenorrheic women was found to be lower than that of the proliferative glandular cells in the control women (p < 0.03), whereas the Ki-67 index of glandular cells in the tamoxifen-treated postmenopausal patients was higher than that of the glandular cells in the control women (p < 0.02). No EGFR overexpression was found in the glandular cells of the tamoxifen-treated premenopausal patients, but expression of EGFR was high in glandular cells of the tamoxifen-treated postmenopausal patients associated with a high Ki-67 index. In competition with ovarian estrogen secretion, tamoxifen may have an antiestrogenic effect on the endometrium, but tamoxifen probably has an estrogenic effect in the absence of ovarian estrogen secretion. This estrogenic effect of tamoxifen may be associated with an EGFR autocrine system.

ABSTRACT

To clarify the tumor behavior in borderline ovarian tumors, we examined the characteristics of neovascularization in these tumors by using a transvaginal color Doppler ultrasound (TV-CDU). Twelve patients with borderline ovarian tumors were preoperatively evaluated for the characteristics of intratumoral blood flow by TV-CDU, using both the resistance index (RI) and pulsatility index (PI). As a control group, 100 patients with benign ovarian tumors and 31 patients with malignant ovarian tumors were also examined by TV-CDU. An intratumoral blood flow was significantly detected in both borderline (91.6%; 11/12) and malignant ovarian tumors (90.3%; 28/31), but not in benign ovarian tumors (53%; 53/100) (P < 0.01). In addition, both the mean RI and mean PI values were significantly lower in the borderline (RI; 0.45, PI; 0.67) and malignant ovarian tumors (RI; 0.39, PI; 0.58) than those in the benign ovarian tumors (RI; 0.61, PI; 1.05) (P < 0.01). In mucinous tumors, the borderline tumors showed a significantly high intratumoral vascularity (P < 0. 01) and both borderline and malignant tumors significantly demonstrated a low-resistance blood flow (P < 0.01), in comparison to those of the benign tumors. Mucinous borderline tumors of the intestinal type also tended to have a lower RI as well as a lower PI value than müllerian type. Regarding neovascularization as represented by intratumoral blood flow characteristics, this study thus suggests that a close relationship exists in the tumor behavior between borderline and malignant ovarian tumors, especially in mucinous epithelial tumors.

ABSTRACT

Small-cell carcinoma of the endometrium is a rare neoplasm, and its aggressive behavior has been reported. We report a case of small-cell carcinoma occurring primarily in the endometrium of a 62-year-old woman with postmenopausal vaginal bleeding and lower abdominal pain. The excised uterus showed a necrotic polypoid mass and histologically displayed an endometrial small-cell carcinoma. Immuno-histochemically, the tumor cells were positive for cytokeratin, the epithelial membrane antigen, neuron-specific enolase, and chromogranin, but were negative for the leukocyte common antigen and Grimelius stain. Ultrastructural analysis revealed the presence of dense core granules in the cytoplasm of tumor cells. The patient died 2 months after surgery because of aggressive behavior of the tumor. We wish to distinguish small-cell carcinoma of the endometrium from conventional epithelial tumors of the endometrium, because of the former's distinctive histopathologic, immunohistochemical, and ultrastructural characteristics.

ABSTRACT

There have been some reports suggesting the effectiveness of medicinal mushrooms in not only keeping health but also preventing and curing diseases as well as recovering from illnesses. However, no uniformity has been observed with its medicinal effect and thus there are some problems in these materials from clinical aspects. Ununiformity of constituents which has resulted from the lack of established optimum culturing methods and inadequacy of experimental approaches are given as the causes of the problems. In the present study, the authors established a culturing method for harvesting fruit bodies with stable constituents by the use of the best cytogenetical technique for Agaricus blazei(CJ-01)which has attracted special interest recently among medicinal mushrooms. Fundamental medical scientific researches have been conducted with the medicinal effect of Agaricus blazei(CJ-01)obtained by the new culturing method by the widely use of immunological and pharmacological approaches. Based on the results of these studies, the author demonstrated the effect scientifically on the cases where the effect had already been observed clinically (hypertension, atopic dermatitis and diabetes).

ABSTRACT

The purpose of this study was to examine the incidence and cause of Clostridium difficile colitis occurring after cisplatin-based combination chemotherapy in ovarian cancer patients. Thirty-three patients with primary ovarian malignancy were treated with cisplatin-based combination chemotherapy ranging from 1 to 12 (mean 4.6) cycles. All patients who developed diarrhea after undergoing the cancer chemotherapy were examined to determine whether or not they were complicated by C difficile colitis. The diagnosis of C. difficile was confirmed by a stool-cytotoxin test and endoscopic examination. Severe C. difficile colitis occurred in 2 patients (6.1%) after receiving cisplatin-based combination chemotherapy for ovarian malignancies. Although both patients recovered from the colitis after the administration of vancomycin, the first case demonstrated a relapse of the colitis after receiving a subsequent course of the same chemotherapy with cisplatin. Both patients were then treated with a carboplatin alternative to cisplatin in the following courses, which resulted in neither a relapse of the colitis nor a recurrence of the malignancies up to this time. This report suggests the importance of searching for the presence of C. difficile and its toxin in patients with diarrhea after undergoing cancer chemotherapy since C. difficile may cause severe colitis. Based on our findings, it is thus concluded that cisplatin may cause C. difficile colitis.

ABSTRACT

The antiemetic efficacy of a combination of granisetron and clonazepam was investigated in 39 gynecological cancer patients treated with cisplatin. Granisetron (3 mg/body/day) was administered by intravenous drip infusion before and 24 hours after anticancer drug administration, and clonazepam was taken orally twice a day. With a combination of granisetron and clonazepam, excellent efficacy was found in 87% (34/39) of the cases. Delayed emesis occurred in 38% (13/34), but the degree of nausea was mild. Clinically, antiemetic therapy with a combination of granisetron and clonazepam demonstrated superior antiemetic effects and seems to be useful for controlling nausea and vomiting associated with cancer chemotherapy.

ABSTRACT

Using the polymerase chain reaction (PCR) to examine the occurrence of bcl-2/JH joining produced by t(14;18) chromosomal translocation, amplified DNA was detected in 2 of 18 lymph nodes showing reactive lymphadenopathy. The PCR was repeated in these two lymph nodes using the same DNA samples, but no amplification was detected at the second attempt. Thus the amplified DNA was considered to be derived from one copy of joined bcl-2/JH in one cell, or from a few copies in a few clonal cells with the same joined bcl-2/JH. These results suggest that false joining of bcl-2/JH at the t(14;18) junction may occur in reactive lymph nodes.

ABSTRACT

Histopathologic changes in lymph nodes were examined from ten patients with mild lymphadenopathy, a few atypical lymphocytes in their peripheral blood, skin lesions, and proviral DNA of human T-cell leukemia virus type I (HTLV-I) in their nodes. The proviral DNA of HTLV-I was detected by southern blot analysis, in situ hybridization, and/or polymerase chain reaction techniques. The lymph nodes showed preserved nodal architecture with diffuse infiltration of small to intermediate-sized lymphocytes in association with scattered transformed lymphocytes and a few immunoblast-like cells in the enlarged paracortex. The infiltrating lymphocytes were positive for CD4, but neither rearrangement nor deletion of T-cell receptors and immunoglobulin heavy chain genes was detected. Eight of ten patients received no therapy, and all patients were alive and healthy more than 5 months after the biopsies. The histologic findings resembled those of a viral infection and could be distinguished from HTLV-I associated lymphomas.

ABSTRACT

Human T-cell leukemia virus type I (HTLV-I) is associated with adult T-cell leukemia/lymphoma (ATLL). To examine the relationship between defective HTLV-I proviruses and clinicopathological features, we examined 95 patients with ATLL showing clonal integration of HTLV-I proviral DNA; 77 patients (81%) showed 1 clonal band, 15 (16%) showed 2 clonal bands, and 3 (3%) showed 3 clonal bands. In addition, the defective proviral form was detected in 28 patients (29%): 23 (30%) of the 77 with 1 clonal band, 4(27%) of the 15 with 2 clonal bands, and 1(33%) of the 3 with 3 clonal bands. The numbers of clonal bands had no association with the presence of defective proviruses. We classified the 95 patients with ATLL into four types according to clinicopathological features (smoldering leukemia, chronic leukemia, acute leukemia, and lymphoma types). The distribution of patients with the defective form was not different among these four types. The HTLV-I genomes must have integrated into the human genome DNA and been deleted partially in the cells. The defective form was kept during the clinical stage. All patients with the defective form showed defect of the gag or/and env region. No patient had a defect of the pX region. These data suggest that the pX region of HTLV-I must have played an important role in ATLL genesis.

ABSTRACT

Lymphoepithelioma of the nasopharynx is a neoplasm known to have a strong association with Epstein-Barr virus (EBV). Using the Southern blot method, polymerase chain reaction (PCR), and/or in situ hybridization, we examined lymph nodes containing metastatic carcinoma, including metastatic lymphoepithelioma, for the presence of EBV genomes in order to determine whether EBV was associated exclusively with lymphoepithelioma. All of six lymph nodes from patients with lymphoepithelioma in the neck were found to have EBV genomes using the above methods. In four of the six cases, the primary site was the nasopharynx, and in the other two no primary site was found. Four of 12 squamous cell carcinomas and one of 18 adenocarcinomas expressed the EBV genome only by PCR, but not by Southern blotting or in situ hybridization, probably due to the presence of latent EBV in lymphocytes. These results indicate that metastatic carcinoma in lymph nodes showing EBV genomes revealed by Southern blotting or in situ hybridization is lymphoepithelioma, and that the nasopharynx is very likely the primary site.
