This paper describes the computed tomographic features of ovarian masses in dogs. The CT images of female dogs with a confirmed histological diagnosis of ovarian tumors or ovarian cystic diseases were studied retrospectively. Seven dogs met the inclusion criteria. The morphological features of ovarian tumors and ovarian cystic diseases coincided to a certain degree, but ovarian tumors tended to be predominantly solid. Objective measurements of Hounsfield units (HU) suggest that benign lesions may show lower HU values than malignant tumors and mild contrast enhancement because of the small soft tissue composition. CT is useful for a differential diagnosis of ovarian masses by providing additional information on the imaging features of the masses and an evaluation of metastases.

To establish the differential diagnosis and functional status in ovarian cystic cows, progesterone(P$_4$) and estrogen(E$_2$) level of cystic follicular fluid, ultrasonography for measuring the cystic diameter and thickness of cystic wall, and histological findings were investigated in cystic ovaries from slaughtered Korean native cows. Ovarian follicles were classified as systic if the diameter was greater than 25 mm by ultrasonography. Ovarian cysts < 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and >10 ng/ml E$_2$ concentration were classified follicular cyst, ovarian cysts 3 mm of cystic wall thickness, 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified luteal cyst, and ovarian cysts 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified non-functional ovarian cyst, respectively. Also ovarian cysts were classified 8 types by anatomical and hisctological findings. Ovarian cysts with corpus luteum were 3 of 73 cows and ovarian cysts without corpus luteum were 70 cows. The incidence rates of 8 various types of ovarian cysts were as follows; 2Aa 56.2%, 2Ba 20.5% and 2Ab 15.1%, respectively. The incidence rates of ovarian cysts without corpus luteum were follicular cyst 76.7% and luteal cyst 19.2%. The thickness of cystic wall were lAb 3.9 mm, 2Ab 3.3 mm and 2Bb 3.2 mm, and the cystic fluid P$_4$ concentrations were above 10.0 ng/ml in lAb, 2Ab and 2Bb, respectively. There was significantly correlations between the thickness of cystic wall and cystic fluid P$_4$ concentration in ovarian cysts(p<0.05). The ovarian cyst was classified follicular cysts, luteal cyst and non-functional ovarian cyst by hormone analysis. The luteal cyst was accuratly dignosed by cystic wall thickness. But follicular cysts was misdiagnosed 13 cows of 56 cystic cows. The 13 cystic cows was determined as had non-fuctional ovarian cysts. The cystic fluid P$_4$ concentration was 3.3 ng/ml in follicular ovarian cysts and 30.1 ng/ml luteinized ovarian cysts. There was significantly positive correlations between thickness of cystic wall and serum P$_4$ concentration in follicular(r$^2$ =0.59, p<0.001) and luteal cysts(r$^2$=0.65, p<0.001). These results indicated that ovarian cysts had various stages of degeneration and luteal cyst was accuratly diagnosed measurement of cystic wall thickness by ultrasonography, but follicular cysts was not diagnosed only cystic diameter and cystic wall thickness. In conclusion, it is suggest that ovarian cysts was diagnosed by combination of clinical sign and anatomical cystic features.

Objectives: To determine the prevalence and predicting factors of ovarian metastasis, and evaluate the histology of other ovarian neoplasms in women with early-stage cervical cancer. Methods: The medical records of women with cervical cancer stage IA-IIA who underwent primary surgical treatment at Siriraj Hospital, Mahidol University from January 2007 to December 2011 were used for the study. Demographic, clinical and histopathologic data of the women who underwent salpingo-oophorectomy were reviewed. Results: Of 264 women, the mean age was 52.3 years. The types of hysterectomy procedures were composed of 210 radical hysterectomy, 9 modified radical hysterectomy, 40 simple hysterectomy, and 5 abandoned hysterectomy. The prevalence of ovarian metastasis was 0.76% (2/264). All of ovarian metastatic patients were older than 60 years old, postmenopause, and had macroscopical stage IB1 cervical cancer. Others ovarian tumors were found in 7 patients including 1 synchronous ovarian carcinoma, 1 serous cystadenoma, 1 fibroma, and 4 teratoma. Conclusions: In cases of early-stage cervical carcinoma of the population studied, ovarian preservation could be another option in <60-year-old patients, with non-neuroendocrine cell type, stage IA, and no extracervical or ovarian lesions.

Objectives: The aim of this paper is to report that herb medicine effects on four infertility patients with ovarian cysts and the menstrual irregularity as a result of ovarian hyperstimulation syndrome. Methods: Four infertility patients with ovarian cysts had the same symptom of menstrual irregularity for preparing In Vitro Fertilization (IVF). They were treated by twice a day herb medication Changbudodam-tang. Then we observed the effects of treatments by regularity of menstruation, checking with ultrasonography of ovarian cyst size. Results: After herb treatments, the sizes of ovarian cysts decreased and one of them disappeared. Above all, menstrual regularity was recovered for preparing IVF. So they could have a positive progress of IVF. Conclusions: These cases show that herb medicine has its effective treatments for the implantational surroundings on infertility patients with ovarian cyst and menstrual irregularity because of ovarian hyperstimulation syndrome.

Objective: To analyze differential diagnostic accuracy of urinary human epidydimis secretory protein 4 (HE4) in patients with ovarian tumors. Materials and methods: In the case-control study 23 patients with ovarian cancer, 37 patients with benign ovarian tumors and 18 women in the control group were included. Serum CA125 values and urinary concentrations of HE4were assessed quantitatively. Urinary creatinine concentrations and glomerular filtration rate were also determined and used to calculate ratios to HE4. Results: Higher urinary HE4 concentrations were observed in patients with late stage ovarian cancer (p=0.001) and also in patients with early stage ovarian cancer when compared to patients with benign ovarian tumors (p=0.044). On analysis where all ovarian cancer patients were included, higher diagnostic accuracy was observed with calculated ratio of HE4 to glomerular filtration rate (GFR) to unchanged urinary HE4 concentrations -AUC 0.861 vs. 0.858. When discriminatory accuracy was calculated for urinary HE4/GFR ratio and unchanged urinary HE4 concentrations, the last demonstrated a higher area under the curve - 0.701 vs. 0.602. The urinary HE4/creatinine ratio had lower discriminatory characteristics than unchanged concentrations of urinary HE4. However, HE4 serum concentration was more accurate for discrimination of patients with benign and malignant ovarian tumors when compared to urinary HE4 and CA125 in sera (AUCs were 0.868 for serum HE4 and 0.856 and 0.653 for urinary HE4 and CA125, respectively). Conclusions: Ovarian cancer patients have higher urinary concentrations of human epidydimis secretory protein 4 than patients with benign ovarian tumors. Urinary HE4 has comparable discriminatory accuracy with serum HE4 for benign and malignant ovarian tumors and can be recommended as a non-invasive ovarian cancer risk assessment method.

To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone concentration and ulrasonography for measuring the cyclic area, thickness of cystic wall and echogenicity of corpus luteum were investigated in cystic ovaries from slaughtered cows. The incidence rates of ovarian cysts were follicular cyst 69.2% and luteal cyst 30.8%. The incidence rates of 8 various types of ovarian cysts were as follows; 2Ba 32.3%, 2Aa 25.8% and 2Bb 14.5%, respectively. The thickness of cystic wall were 2Bb 3.93mm, 2Ab 3.70mm and 1Aa 1.93mm and the serum progesterone concentrations were above 1.0ng/$m\ell$ in 2Ab, 2Bb and IAa, respectively. The cystic area of ovarian cysts with corpus luteum was 288.30mm2, but ovarian cysts without corpus luteum 542.30$\textrm{mm}^2$, and the thickness of cystic wall 2.12mm and 2.40mm, respectively. The serum progesterone concentration was 1.91ng/$m\ell$ in ovarian cysts with corpus luteum and 1.20ng/$m\ell$ ovarian cysts without corpus luteum. There was not the correlations between thickness of cystic wall and serum progesterone concentration in ovarian cysts with corpus luteum, whereas, was the correlations in ovarian cysts without corpus. These results indicated that PGF2$\alpha$ analogues can be choice for treating the ovarian cysts with corpus luteum because serum progesterone concentrations were above 1.0ng/$m\ell$ in ovarian cysts with corpus luteum. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosing and choicing of treatment remedy in cystic ovaries of bovine.

To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone (P$_4$) concentration and ultrasonography for measuring the cystic wall thickness and diameter of cyst and corpus luteum were investigated from slaughtered cows with ovarian cysts. Ovarian cysts were classified 8 types by the number of cyst, cystic wall thickness and present of corpus luteum. Ovarian cysts with corpus luteum were 11 (13.6%) of 81 cows and ovarian cysts without corpus luteum were 70 (86.4%) cows. The incidence rates of 8 various types of ovarian cysts were as follows; 2Ba 33.3%, 2Aa 25.9% and 2Bb 14.8%, respectively. The incidence rates of ovarian cysts without corpus luteum were follicular cyst 59.2% and luteal cyst 27.2%. The cystic wall thickness were 2Ab 3.7 mm and 2Bb 3.5 mm, and the serum P4 concentrations were above 2.0 ng/ml in 1Aa, 1Ab, 1Ba, 2Ab and 2Bb, respectively. In ovarian cysts with corpus luteum, the correlation coefficients between corpus luteum area and serum P$_4$ concentration were 0.45. In ovarian cysts without corpus luteum, there was significantly positive correlations between cystic wall thickness and serum P$_4$ concentration ($r^2$= 0.54, p＜0.01). These results indicate that PGF$_2$$\alpha$ analogues can be choice for treatment of ovarian cysts with corpus luteum and above 3 mm the cystic wall thickness because serum P$_4$ concentrations were above 2.0 ng/ml in ovarian cysts with corpus luteum and thickened cystic wall. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosis and selection of treatment remedy in cystic ovaries of bovine.

Objective: Bilateral uterine artery ligation (UAL) is a fertility-preserving procedure used in women experiencing postpartum hemorrhage (PPH). However, the long-term effects of this procedure on ovarian function remain unclear. The aim of this study was to investigate whether bilateral UAL compromised ovarian reserve and ovarian blood supply. Methods: This prospective study included 49 women aged between 21 and 36 years who had undergone a cesarean section for obstetric indications. Of these, 25 underwent uterine bilateral UAL to control intractable atonic PPH. The control group consisted of 24 women who had not undergone bilateral UAL. Standard clinical parameters, the results of color Doppler screening, and ovarian reserve markers were assessed in all participants at 6 months after surgery. The clinical parameters included age, parity, cycle history, body mass index, and previous medication and/or surgery. Color Doppler screening findings included the pulsatility index (PI) and resistance index (RI) for both the uterine and ovarian arteries. The ovarian reserve markers included day 3 follicle-stimulating hormone (FSH) levels, antral follicle count, and $anti-M\ddot{u}llerian$ hormone (AMH) levels. Results: There were no significant differences in the ovarian reserve markers of day 3 FSH levels, antral follicle count, and AMH levels between the study and control groups (p> 0.05 for all). In addition, no significant differences were observed in the PI and RI indices of the uterine and ovarian arteries (p> 0.05 for all). Conclusion: In this study, we showed that bilateral UAL had no negative effects on ovarian reserve or ovarian blood supply, so this treatment should be used as a fertility preservation technique to avoid hysterectomy in patients experiencing PPH.

Background: The primary objective of this study was to assess the proportion of malignancies in ovarian masses during $1^{st}$ January 2002, to $31^{st}$ December 2011 at the Department of Obstetrics and Gynecology, King Chulalongkorn Memorial Hospital. A secondary objective was to evaluate associations with patients' clinical characteristics and ovarian malignancy proportion and subtypes. Materials and Methods: Retrospective descriptive study analyzed data of ovarian masses larger than 3 centimeters in maximal diameter, from the division of Gynecologic Cyto-Pathology at KCMH. SPSS software version 17 (SPSS, Inc, Chicago, IL, USA) was used. Results: A total number of 6,115 patients were included. Among the total ovarian masses studied, 13.7% were malignant. After the age of sixty, the proportion reached almost 40%. It was also above 20% in women younger than 20 years old. During premenarche period, proportion of ovarian malignancies was 50%. Only 1% of ovarian masses were found to be malignant during the pregnancy and post-partum periods. Parity decreased the probability of ovarian malignancy during postmenopausal years. Period of menopause did not have any impact on this probability. During the first two decades of life, germ cell malignancy dominated. As the age increased, the percentage of surface epithelial-stromal malignancy increased with a peak at the fifth decade. In contrast, malignant sex cord-stromal cell tumors occurred at a constant rate in each age group after the thirties. Conclusions: Proportion of ovarian cancers in each age group, menstrual and pregnancy status are similar. However there are differences in the distribution of ovarian subtypes especially for the surface epithelial-stromal category.
