A case of ovarian endometrioid adenocarcinoma with yolk sac tumor in a 35-year-old woman.

Ovarian yolk sac tumor (YST) is a malignant ovarian neoplasm differentiated from primordial germ cells that occur in young age, while endometrioid carcinoma (ECA) is a müllerian epithelial tumor that usually occurs in older patients. The coexistence of an ovarian ECA and YST component is very rare. Only 12 cases have been reported until now according to a Medline search of the English literatures. We present a case of a simultaneous ECA and a YST component in a 35-year-old woman. Exploratory laparotomy was performed. The parts of both ovaries that showed an endometrioid-like glandular pattern were positive for cytokeratin 7 and negative for AFP, but the YST component was negative for cytokeratin 7 and positive for AFP. After completion of four courses of BEP chemotherapy, two courses of taxane and carboplatin chemotherapy were added. The patient failed to respond and succumbed to the disease after 12 months of follow-up.

Fitz-Hugh-Curtis Syndrome: single centre experiences.

This study was conducted to report 10 cases of Fitz-Hugh-Curtis Syndrome (FHCS) diagnosed with CT and 101 cases of FHCS-like lesion that suggested perihepatitis during laparoscopic surgery. We reviewed retrospectively the images of 3,674 laparoscopies for obstetrical and gynaecological diseases and analysed 10 cases of FHCS diagnosed by clinical patterns and CT. All the 10 cases showed liver capsular enhancement on CT. Among the 3,674 laparoscopies, we found 101 cases (2.7%) with FHCS like lesion. Among them, 23 cases were during laparoscopic procedure for endometriosis, 16 for gynaecological malignant tumours, 16 for benign adnexal diseases excluding endometriosis, 13 for uterine leiomyoma, 7 for pelvic inflammatory disease, 2 had peritoneal tuberculosis and 21 for other gynaecological diseases. Further consideration should be given for the causes of FHCS other than N. gonorrhoeae and C. trachomatis. Because FHCS may represent various clinical phases, other considerations and clinical classifications are necessary for treatment.

Elastic properties and apparent density of human edentulous maxilla and mandible.

The aim of this study was to determine whether elastic properties and apparent density of bone differ in different anatomical regions of the maxilla and mandible. Additional analyses assessed how elastic properties and apparent density were related. Four pairs of edentulous maxilla and mandibles were retrieved from fresh human cadavers. Bone samples from four anatomical regions (maxillary anterior, maxillary posterior, mandibular anterior, mandibular posterior) were obtained. Elastic modulus (EM) and hardness (H) were measured using the nano-indentation technique. Bone samples containing cortical and trabecular bone were used to measure composite apparent density (cAD) using Archimedes' principle. Statistical analyses used repeated measures ANOVA and Pearson correlations. Bone physical properties differed between regions of the maxilla and mandible. Generally, mandible had higher physical property measurements than maxilla. EM and H were higher in posterior than in anterior regions; the reverse was true for cAD. Posterior maxillary cAD was significantly lower than that in the three other regions.
