Evaluation fetal heart in the first and second trimester: Results and limitations.

Background: Cardiac heart defects affect nearly 6-12 per 1000 live births in the general population and are more frequent than common trisomies. Aim: To assess the efficacy and technical limitations of first-trimester fetal heart evaluation in the 11-14th-weeks' scan and comparison with the second-trimester anatomical exam by ultrasound. Material and Method: Between April 2015 and July 2020, medical records and ultrasound data of 3295 pregnancies who underwent first-trimester fetal anatomy exams by ultrasound were reviewed retrospectively. All ultrasound exams were performed by the same two operators (TUKD, OP) with transabdominal transducers. Fetal situs, four-chamber view, outflow tracts, and three-vessel trachea view are the cornerstones of first-trimester fetal heart examination. Conventional grayscale mode and high-definition power Doppler mode were utilized. The same operators re-examined all cases between the 18 and 23 weeks of gestation by ISUOG guidelines. Results: We performed a combined transvaginal and transabdominal approach for only 101 cases (3.06%). The mean maternal age was 31.28 ± 4.43, the median gestational age at the first-trimester ultrasound exam was 12.4 weeks, and the median CRL was 61.87 mm (range was 45.1-84 mm). Even combined approach situs, cardiac axis, and four-chamber view could not be visualized optimally in 28 cases (0.7%). Outflow tracts were visualized separately in 80% (2636 in 3295) cases. Three vessel-trachea views were obtained in 85.4% (2814 in 3295) cases by high-definition Doppler mode. There were 47 fetuses with cardiac defects in 3295 pregnancies with the known pregnancy outcome. Ten cases had abnormal karyotype results. Thirty-two fetuses with cardiac anomalies (9.7 in 1000 pregnancies) were detected in the first-trimester examination, and the remaining 15 (4.55 in 1000 pregnancies) cases were diagnosed in the second-trimester examination. The prevalence of congenital cardiac anomalies was 14.25 in 1000 pregnancies. Fifteen cases were missed in the first-trimester exam. Also, ten fetuses which had abnormal cardiac findings in the first-trimester exam were not confirmed in the second-trimester exam. Sensitivity, specificity, positive, and negative predictive values were calculated as 65.3%, 99.7%, 66.8%, and 99.67%, respectively. Conclusion: Late first-trimester examination of the fetus is feasible and allows earlier detection of many structural abnormalities of the fetus, including congenital heart defects. Suspicious and isolated cardiac abnormal findings should be re-examined and confirmed in the second-trimester exam. Previous abdominal surgery, high BMI, and subtle cardiac defects can cause missed cardiac abnormalities.

Malignant fibrous histiocytoma of the ovary: a case report.

Malignant fibrous histiocytoma is the most common type of soft tissue sarcoma in adults. Primary malignant fibrous histiocytoma of the ovary is extremely rare, with only three previously reported cases. We reported a rare and uncommon localization of malignant fibrous histiocytoma in a 22-year-old woman. She was referred for adjuvant chemotherapy to our center with the diagnosis of storiform-pleomorphic malignant fibrous histiocytoma. A left adnexal mass was detected by computed tomography of the lower abdomen. Therefore, we decided to perform reoperation for debulking, and left salpingo-oopherectomy, total hysterectomy, infracolic omentectomy, and resection of all visible peritoneal implants were performed. Histopathologic examination revealed inflammatory, malignant fibrous histiocytoma. Immunohistochemical staining confirmed positive reactions to alpha 1-antitrypsin, vimentin, CD68, and S100. The management of malignant fibrous histiocytoma is controversial because of the heterogenous nature of the disease. Resection of all macroscopic disease is independently associated with improved disease-specific survival, and adjuvant chemotherapy for nonmyxoid variants could be acceptable alternatives if the surgical margins are tumor free.

Treatment of viable cesarean scar ectopic pregnancy with suction curettage.

OBJECTIVE: Pregnancy in previous cesarean scar is the rarest form of ectopic pregnancy. All reported cases in the literature that were treated with uterine curettage either become unsuccessful or complicated. We aimed to present a case of cesarean scar ectopic pregnancy that was successfully treated with suction curettage without any additional therapy. CASE: A 32-year-old asymptomatic woman, gravida 2, para 1 was referred to our hospital with the possible diagnosis of cervical ectopic pregnancy. Transvaginal and transabdominal sonographic examination revealed the diagnosis of viable ectopic pregnancy in a previous cesarean scar. Suction curettage with carman canulles was performed under transabdominal ultrasonographic guidance. beta-hCG decreased progressively postoperatively. CONCLUSION: Suction curettage under ultrasonography guidance can be used in termination of selected cases (early diagnosed, without symptoms that necessitates emergency intervention) of cesarean scar pregnancy.

Extraovarian nongestational choriocarcinoma in a postmenopausal woman.

Primary extrauterine choriocarcinoma especially in the postmenopausal period is very rare. A 69-year-old woman, complaining of back pain, weakness, and severe fatigue with gross hematuria, was found to have paraovarian pelvic mass and underwent laparotomy. At the operation, a mass located in the right adnexal region, extending to the retroperitoneum and within the normal pathway of germ cell migration, was observed. Other peritoneal surfaces, the uterus, both the ovaries, and fallopian tubes were normal. Total abdominal hysterectomy, bilateral salphingo-oophorectomy, and excision of the right adnexal mass were performed. The histopathological report showed an extrauterine, nongonadal pure choriocarcinoma. As single-agent chemotherapy with methotrexate was ineffective, the patient received multiagent chemotherapy and responded well to the treatment. After 18 months following chemotherapy, the patient was disease free. Extraovarian nongestational choriocarcinoma can be seen within the normal pathway of germ cell migration and responds to chemotherapy-like gestational choriocarcinoma.

Postmenopausal endometrial cancer screening: is there a correlation between transvaginal sonographic measurement of endometrial thickness and body mass index?

OBJECTIVE: The aim of this study was to correlate the body mass index with transvaginal sonographic measurement of endometrial thickness in a cohort of postmenopausal women who were admitted for endometrial cancer surveillance. MATERIAL AND METHODS: Transvaginal sonographic measurement of endometrial thickness was performed in 97 postmenopausal women who attended the gynecology clinic for endometrial cancer screening with no history of hormone replacement therapy and correlated with body mass index. Baseline characteristics including age, years since menopause and body mass index were recorded for each subject. The relationship between transvaginal sonographic endometrial thickness and baseline characteristics was assessed in each. RESULTS: Body mass index was significantly correlated with years since menopause (r = 0.292, p = 0.004) and age (r = 0.243, p = 0.01) but not with endometrial thickness (r = -0.07, p = 0.454). Endometrial thickness versus time since menopause correlation was found to be significant (r = 0.274, p = 0.03) in patients with a body mass index lower than 30. CONCLUSION: The present findings indicate that endometrial thickness does not differ with body mass index in the screening of postmenopausal women for endometrial cancer.

Villoglandular papillary adenocarcinoma of the uterine cervix with immunohistochemical characteristics.

Villoglandular papillary adenocarcinoma of uterine cervix has been recently described and to date fewer than a hundred cases have been reported in the world literature. Here we present a 38-year-old woman who underwent radical hysterectomy combined bilateral pelvic lymphoadenectomy and after 28 months postoperatively no lymph node metastasis and no evidence of recurrent disease ocurred. Immunohistochemically Ki-67 overexpression was detected in the tumour, with no immunoreactivity with p53, estrogen and progesteron receptors and broadly-reactive human papilloma virus including types 6, 11, 16, 18, 31, 33, 42, 51, 52, 56, and 58. In this paper, clinical, macroscopical, microscopical and immunohistochemical characteristics of this tumour are reviewed.

Accuracy of frozen section diagnosis in borderline ovarian malignancy.

This study was conducted to determine the accuracy of frozen section diagnosis in borderline ovarian tumors. Thirty-three patients were evaluated on the basis of frozen sections between February 1992 and December 1997. Frozen section diagnosis and final diagnosis were divided into three categories: for frozen section diagnosis: 1 = benign, 2 = borderline, 3 = 'at least' borderline, and for final diagnosis: 1 = benign, 2 = borderline, 3 = cancer. Three patients with a benign diagnosis according to their frozen sections were reclassified as borderline in the final diagnosis and all of them were of the mucinous type. The frozen section diagnosis of tumors of borderline malignancy was inaccurate in 3 of 23 patients. Four of 7 patients with at least borderline according to their frozen section diagnosis had invasive cancer at the final diagnosis. The correlation between frozen section diagnosis and final pathological examination was 72.7% (24/33). We found 9% (2/22) inaccurate results in the serous type and 36.6% (4/11) in the mucinous type. The sensitivity and specificity of frozen section diagnosis were found to be 86.95 and 57.14%, respectively. We concluded that frozen section evaluation in identifying a borderline ovarian malignancy is accurate enough to exclude the presence of a benign pathology.
