Endodermal sinus tumors (EST) are rare germ cell ovarian malignancies occurring primarily in young women. A retrospective review of the Magee-Womens Hospital tumor registry revealed eight cases of pure EST and two mixed tumors in which the EST component was predominant. Mean patient age was 18.2 years. Abdominal pain was the most common presenting symptom and a pelvic mass was palpable in all patients. Four patients are currently alive and well with no evidence of disease. All were treated with surgery and combination chemotherapy. Flow cytometric DNA content analysis of paraffin-embedded tumor tissue identified similar aneuploid cell populations in three of five tumors analyzed with relative peak positions of 1.72, 1.62, and 1.70. The management of women with endodermal sinus tumor remains controversial with regard to type of chemotherapy employed and the use of second-look laparotomy. The prognosis role of flow cytometric DNA content analysis is yet to be determined.

Reported is a rare case of a 2.5cm endodermal sinus tumor (EST) that was included within a 11 x 10.5 cm serous cystadenoma. A 24-year-old female suddenly complained of abdominal pain caused by having undergone an intestinal torsion of a left ovarian tumor. After a unilateral salpingo-oophorectomy the serum AFP was 219.8 ng/ml. The patient then received two cycles of cis-platinum, vinblastine and bleomycin combination chemotherapy. After one cycle, the serum AFP decreased to a normal level and the woman has remained free of disease 6 months after the discovery of her tumor. In this case, fortunately, this torsion of a serous cystadenoma enabled us to find the EST at a very early stage.

Spontaneous perforation of the common bile duct (CBD) is a rare event in adults. Most cases of CBD perforation are iatrogenic after invasive procedures such as endoscopic retrograde cholangiopancreatography (ERCP) or cholecystectomy. We report a case of an 81-year-old woman who presented with severe right upper abdominal pain, fever, and chills. Abdominal CT showed multiple gallbladder and CBD stones and loculated fluid collection in the inferoposterior portion of the stomach. ERCP showed the leakage of contrast media into the peritoneal cavity from the CBD. We performed endoscopic sphincterotomy (EST) and endoscopic nasobiliary drainage (ENBD) to decompress the CBD instead of emergent surgical intervention. One week later, cholangiography via ENBD tube revealed that there was no more leakage of the contrast media from the CBD. We performed cholecystectomy, removal of the CBD stones after exploration of the CBD, and T tube insertion. The perforated site of the CBD was closed and there was no more fluid collection in the inferoposterior portion of the stomach. Medical treatment including endoscopic procedures was useful for healing of the perforated CBD.

The recurrence of benign sacral teratomas is a small but significant possibility. Recurrence as an endodermal sinus tumor (EST) with epidural metastases, however, has not been previously reported. The authors describe a case of a mature sacrococcygeal teratoma in a 4-day-old female patient that recurred after 22 months as an EST with epidural metastases. The child presented with abdominal pain, urinary retention, and difficulty walking. On imaging, a large pelvic mass and an epidural spinal mass were revealed. The patient's alpha-fetal protein (AFP) level was 68,000 ng/ml. Her neurological examination was significant for 3/5 plantar and dorsiflexion strength bilaterally. The patient underwent L-3, L-4, and L-5 bilateral laminectomies followed by subtotal resection of the recurrent pelvic tumor. Pathological testing of samples of both the recurrent pelvic and the extradural spinal tumors led to a diagnosis of EST. The patient underwent four cycles of chemotherapy with normalization of her AFP level to 13 ng/ml. In the weeks that followed, her AFP level steadily rose again to 167 ng/ml. Follow-up imaging revealed no tumor recurrence. The patient underwent a second course of chemotherapy followed by two tandem courses of high-dose chemotherapy with autologous stem-cell rescue. Since completing this therapy the patient has been clinically stable with an AFP level of 1.3 ng/ml for 14 months. At the 1-year follow-up examination, her plantar and dorsiflexion strength had markedly improved to 4+/5 bilaterally. To the authors' knowledge, this is the first case of a mature sacrococcygeal tumor that recurred as an EST and caused spinal canal compromise.

Okadaic acid (OA), a marine toxin produced by dinoflagellates, can accumulate in various bivalve molluscs. In humans, consumption of OA induces acute toxic effects like diarrhoea, nausea, vomiting and abdominal pain. OA is a potent inhibitor of protein phosphatase 1 (PP1) and 2A (PP2A), enzymes that are known to be critical regulators of embryonic development. To determine the embryotoxic potential of OA, we performed two independent cellular in-vitro assays, both of which are applicable for the detection of teratogenic compounds: (i) the validated embryonic stem cell test (EST) based on the morphological analysis of beating cardiomyocytes in embryoid bodies and (ii) the F9 cell assay quantifying the induction of cell differentiation by measuring the emitted luminescence of a reporter gene. In the presence of OA, beating cardiomyocytes in the EST were inhibited and the reporter gene in transiently transfected F9 cells was activated. Furthermore, OA treatment led to rapid morphological changes including cell rounding, the loss of cell-cell contacts and changed electrical impedance as monitored in real time by the xCELLigence system. The two independent bioassays (EST and F9 cell test) detected OA as a potential embryotoxic compound, since OA influences the differentiation process of cultured murine embryonic cells.
