The Effects of the Use of Diluted Bupivacaine in Sequential Combined Spinal and Epidural Anesthesia for Cesarean Delivery on Maternal Hypotension and Motor Block after Surgery: A Retrospective Observational Study.

Background: Maternal hypotension is a common hemodynamic consequence of spinal anesthesia during cesarean delivery, but low-dose spinal anesthesia (<9 mg bupivacaine) ensures stable hemodynamics and reduces motor block. The purpose of this retrospective observational study was to examine the effects of baricity of intrathecal administration of diluted bupivacaine in combined spinal-epidural anesthesia (CSEA) for cesarean delivery on maternal hypotension and motor block after surgery.

Methods: The anesthesia and nursing records of 35 patients who had given birth by cesarean delivery under CSEA with intrathecal administration of plain or hyperbaric bupivacaine diluted in cerebrospinal fluid were reviewed.

Small cell carcinoma of the ovary: clinical and biological study.

Ovarian small cell carcinoma of hypercalcemic type is a rare neoplasm that typically occurs in young females. We describe three cases of ovarian small cell carcinoma of hypercalcemic type occurring in patients aged 24, 37, and 25 years. The first patient had stage IIc disease and had primary surgery with a left salpingo-oophorectomy and omentectomy, followed by chemotherapy with cisplatin and etoposide.

Overexpression of HER-2/neu is not a risk factor in ovarian clear cell adenocarcinoma.

Objective: To evaluate the significance of the expression of HER-2/neu as a prognostic factor, we retrospectively examined its overexpression rates chiefly in ovarian clear cell adenocarcinoma (CCA) and their relationships with FIGO stage, lymph node metastasis, and prognosis.

Methods: In addition to 90 specimens of CCA (stage I, 52; stage II, 7; stage III, 28; stage IV, 3) obtained between 1987 and 2002, 19 specimens of serous adenocarcinoma (S), 19 specimens of mucinous adenocarcinoma (M), and 19 specimens of endometrioid adenocarcinoma (E) collected at initial surgery were studied. The expression of HER-2/neu was immunohistologically scored on a scale of 0 to 3+ according to the HercepTest scoring system, and 2+ and 3+ were regarded as overexpression.

Preoperative diagnosis of malignant transformation arising from mature cystic teratoma of the ovary.

Objective: Mature cystic teratoma of the ovary (MCT) is the most common ovarian cystic disease in young women. Although it is a rare occurrence, some cases develop malignant transformation (MT), which results in serious consequences. However, MT is currently diagnosed only by postoperative pathology in most cases.
