Mature cystic teratoma of the uterosacral ligament successfully treated with laparoendoscopic single-site surgery.

Objective: Although the majority of teratomas are encountered in the ovary, extragonadal mature cystic teratoma is an unusual disease entity, and the most common site is the omentum.

Case Report: The occurrence of this tumor on a uterosacral ligament is extremely rare with enigmatic etiology. To our knowledge, there have been only three cases reported to date that describe a mature cystic teratoma of the uterosacral ligament, and this is the first report of successful treatment of these rare tumors with laparoendoscopic single-site surgery (LESS).

Pregnancy outcomes according to increasing maternal age.

Objectives: To investigate the risks of increasing maternal age on the perinatal and obstetric outcomes.

Materials And Methods: Information about 29,760 singleton pregnancies delivered between 2005 and 2008 was extracted from our database. Patients were categorized into four groups according to age: 20-29 years, 30-34 years, 35-39 years, and ≥40 years.

Adenoma malignum of the uterine cervix: Clinicopathologic analysis of 18 cases.

The aim of this study was to evaluate the clinical and pathologic features of a rare tumor (adenoma malignum, AM). We retrospectively analyzed the medical records of 18 patients diagnosed with AM at a single institute between March 1992 and November 2009. The median age of the patients was 45.

Clinical analysis of ovarian pregnancy: a report of 49 cases.

Objective: To clinically analyze cases of ectopic ovarian pregnancy and to generate data regarding the evaluation and management of suspected ectopic ovarian pregnancies.

Study Design: We retrospectively analyzed 49 ovarian pregnancies that were surgically treated at Cheil General Hospital and Women's Healthcare Center between January 1996 and December 2009. We analyzed patient age, parity, symptoms, risk factors, preoperative diagnosis, and ovarian pregnancy type.

Para-aortic lymphadenectomy for primary fallopian tube cancer.

Objective: To investigate the topography of lymph node spread and the need for para-aortic lymphadenectomy in primary fallopian tube cancer (PFTC).

Methods: Twenty-six women were diagnosed with PFTC at Cheil General Hospital and Women's Healthcare Center, Seoul, Korea, between March 1992 and November 2009. Of the 26 patients, we retrospectively analyzed 15 patients who underwent complete staging surgery, including bilateral pelvic and para-aortic lymphadenectomy.

Primary fallopian tube carcinoma: a clinicopathological analysis of a rare entity.

Background: The aim of this study was to evaluate the clinical and pathological features of a rare tumor, primary fallopian tube carcinoma (PFTC).

Materials And Methods: We retrospectively analyzed the medical records of 26 patients who were diagnosed with PFTC at Cheil General Hospital and Women's Healthcare Center between March 1992 and November 2009.

Results: Median patient age was 54.

Adaptive global synchrony of inferior olive neurons.

This paper treats the question of global adaptive synchronization of inferior olive neurons (IONs) based on the immersion and invariance approach. The ION exhibits a variety of orbits as the parameter (termed the bifurcation parameter), which appears in its nonlinear functions, is varied. It is seen that once the bifurcation parameter exceeds a critical value, the stability of the equilibrium point of the ION is lost, and periodic orbits are born.
