Infections in pregnancy with Ureaplasma urealyticum have been associated with a wide range of adverse outcomes, such as early abortion, stillbirth, prematurity, and neonatal morbidity and mortality. Causality has been difficult to demonstrate secondary to the high prevalence of asymptomatic lower genital tract (LGT) colonization and culture data from inaccessible or potentially contaminated sites. Between 1985 and 1989, 2461 second-trimester genetic amniocenteses were evaluated at the cytogenetics section of the Children's Hospital Medical Center of Akron. All were cultured for the genital mycoplasmas: Mycoplasma hominis and Ureaplasma urealyticum. A total of nine patients were positive, all for Ureaplasma urealyticum, with one patient excluded because of subsequent therapeutic abortion. In addition, complete follow-up data, such as indication for amniocentesis, serum alpha-fetoprotein levels, gestational age at parturition, and outcome of pregnancy, were available on 86 Ureaplasma-negative (U-) patients during an approximate 2-year span within the time-frame of the study. This was in part due to physician response to a questionnaire sent after amniocentesis. Of the eight positive cultures, 100 per cent were associated with an adverse outcome, defined as fetal loss or premature delivery. This was significant compared with the U- group (p less than 0.001) with a more than eight times greater risk of adverse outcome. Six (75 per cent) resulted in spontaneous miscarriage within 4 weeks of amniocentesis and at less than 21 weeks' gestation. Two (25 per cent) delivered prematurely, with one (12.5 per cent) neonatal death at 24+ weeks. Histological examination of all eight placentae and the seven fetuses revealed a 100 per cent incidence of chorioamnionitis and pneumonia, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

A patient with embryonal cell carcinoma restricted to the left testicle, without retroperitoneal but with mediastinal lymph node enlargement and highly elevated serum alpha-fetoprotein levels, is presented (T1N4M0). Because stage III of the disease was presumed, he received chemotherapy, which was unfortunately complicated by a bleomycin-induced pneumonitis. At re-evaluation after chemotherapeutic treatment, it appeared that the tumor marker level had decreased exponentially after the operation and that the mediastinal lymph node enlargement was due not to metastatic disease but to sarcoidosis. The necessity of calculating the half-life of tumor markers after operation and histological examination of the mediastinal lymph nodes prior to chemotherapy in such cases, is discussed.

127 men with previously untreated non-seminomatous germ cell tumours (NSGCT) of the testis were given BEP chemotherapy (bleomycin, etoposide and cisplatin) between 1979-1986. Long-term follow-up (median 65 months) has shown an overall 5 year survival of 87.2% (95% confidence limits 81.1%-93.3%). Outcome was related to both tumour volume and serum marker levels of alpha-fetoprotein (alpha FP) and beta human chorionic gonadotropin (HCG), with 5 year actuarial survivals of 97.8%, 72.2% and 26.7% respectively for small, large and very large volume disease defined by Medical Research Council criteria, and 91.2% and 60.8%, respectively, for men with low (alpha FP less than or equal to 500 kU/l and HCG less than or equal to 1000 iU/l) or high serum marker levels. 79 men (62%) had a complete radiological and serum marker response to chemotherapy alone; residual masses postchemotheraphy were resected in 39 patients (31%), showing undifferentiated tumour in only 6 (15%). 23 of the 127 patients (18%) failed to respond or developed recurrent disease after BEP; only 5 were successfully salvaged. Myelotoxicity of treatment was mild with grade 4 toxicity in 2% of chemotherapy courses and 3 episodes of neutropenic sepsis. Mean glomerular filtration rates fell by 15.6% between courses 1 and 4 of BEP. Bleomycin pneumonitis developed in 13% of cases with 1 fatality. So far 21 men have had children following chemotherapy, but semen analysis 12 months or more (median 36 months) after treatment showed azoospermia in 11 out of 54 (20%) men tested. BEP chemotherapy can be regarded as standard treatment for patients with metastatic NSGCT in low-risk categories, but more intensive therapy is required for advanced presentations. Strategies to develop "risk related" treatment are under investigation.

A rare case of hepatocellular carcinoma who developed the complication of the sign of Leser-Trelat is reported. The patient, a 57-year-old male, visited our hospital with complaints of generalized malaise and anorexia. A diagnosis of hepatocellular carcinoma was made based on elevated alpha-fetoprotein measurement, ultrasonography, and hepatic arteriography findings. Chest x-ray film suggested pulmonary metastases of hepatocellular carcinoma. Thereafter, complications of the seborrheic keratosis developed in the trunk and the skin lesion was diagnosed as the sign of Leser-Trelat associated with hepatocellular carcinoma. The patient died of pneumonia 9 months after development of the sign of Leser-Trelat.

An 18-year-old male was admitted with headache, nausea, and vomiting. Computed tomography (CT) revealed an enhanced tumor of the pineal region and hydrocephalus. The tumor was partially resected via a parieto-occipital craniectomy. The histological diagnosis was germinoma. No serum tumor markers such as alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) were detectable. A ventriculo-peritoneal (V-P) shunt was emplaced and radiation therapy (whole brain 59 Gy) given. The tumor and the hydrocephalus regressed completely and he returned to work. Six years later, he experienced constipation and general fatigue. CT and echotomography of the abdomen showed a large peritoneal tumor and ascites. Laboratory investigation demonstrated serum levels of AFP 7640 ng/ml and HCG 150 IU/l, and high ascitic levels of AFP 12,890 ng/ml and HCG 1030 IU/l. AFP and HCG levels regressed after combined chemotherapy. However, he died due to leukopenia and pneumonia. Autopsy found no metastasis of tumor cells to the central nervous system. The peritoneal cavity contained hemorrhagic fluid and a large tumor 4100 g in weight. The tip of the V-P shunt tube was in front of the tumor. No neoplasm was found in the testis, retroperitoneal cavity, thymus, and other organs. The microscopic appearance of the peritoneal tumor was different to the first pineal tumor. The neoplasm was confirmed as a mixed germ cell tumor with teratoma components and suspected to be a metastasis of the pineal tumor through the V-P shunt system.

Outcome of pregnancy after amniocentesis was studied in a randomised controlled trial of 4606 women, age-range 25-34 years, without known risk of genetic disease. Spontaneous abortion rate was 1.7% in the study group after amniocentesis and 0.7% in the control group after ultrasound (relative risk 2.3). In the study group, increased levels of maternal serum alpha-fetoprotein before amniocentesis, perforation of the placenta during amniocentesis, and withdrawal of discoloured amniotic fluid were associated with an increased risk of spontaneous abortion. In the first six weeks after amniocentesis/ultrasound scan, amniotic fluid leakage occurred more often in the study group but there was no difference in the rate of vaginal bleeding. Frequency of postural malformations in the infants in the two groups was the same. In the study group, respiratory distress syndrome was diagnosed more often (relative risk 2.1) and more babies were treated for pneumonia (relative risk 2.5).

Non-germinal cell tumor of the testis is a rare disease, and vascular tumor of the testis is a still rarer disease. Herein, a case of cavernous hemangioma of the testis is reported. A 75-year-old man consulted our department with the complaint of a painless left intrascrotal tumor. Laboratory findings revealed slight leukocytopenia and thrombocytopenia of unknown origin. In chest X-ray, a diffuse reticular shadow was shown and it was considered due to pulmonary fibrosis, but, alpha-fetoprotein and CEA were normal. Left radical orchiectomy was performed under spinal anesthesia. The tumor existed under the tunica albuginea, and the cutting surface of the tumor was brown and irregular. There were hemorrhagic portions in some places. The left epididymis and the left spermatic cord were normal. Histologically, the tumor was diagnosed as cavernous hemangioma. The vascular tumor of the testis is a very rare disease, and only 17 cases have been reported including this case. This case was the 7th case of cavernous hemangioma of the testis, and the first case in Japan. This patient died of respiratory failure due to pulmonary fibrosis and pneumonia. In the autopsy, there was no abnormal finding that was considered to be related to the cavernous hemangioma of the testis.

Several clinical trials have demonstrated that cisplatin-based chemotherapy for primary intracranial germ-cell tumors is effective as a neoadjuvant chemotherapy. In this report, we describe a 6-year-old boy, Down syndrome and Hirschsprung's disease with intracranial pure yolk sac tumor treated by combined chemotherapy with cisplatin, vinblastine, bleomycin and cyclophosphamide (modified VAB-6 regimen). He had been admitted to our hospital because of intractable vomiting, and left facial nerve palsy since 1 month before. An MRI revealed an enlarged mass, 4cm in diameter, in the left cerebello-pontine angle with uniformal enhancement by Gd-DTPA, and bilateral ventricular dilatation. He was found to have increased serum alpha-fetoprotein level (AFP 11, 786ng/ml), but not human chorionic gonadotropin beta-subunit. After a partial resection of the tumor, diagnosed as pure yolk sac tumor, and ventriculo-peritoneal shunt, three courses of combined chemotherapy with cisplatin, bleomycin, vinblastine and cyclophosphamide (modified VAB-6 therapy) were carried out. The serum AFP level returned to normal, and the tumor mass entirely disappeared (a complete response) on MRI after the second course of chemotherapy. However, cisplatin-induced vomiting and mild neutropenia and renal tubular injury developed after the third course of chemotherapy. Irrespective of administration of recombinant human G-CSF and broad spectrum antibiotics, he suffered from pneumonia and died of septic shock and multiple organ failure. Autopsy showed microscopic residual tumors. The combination chemotherapy with cisplatin, bleomycin, vinblastine and cyclophosphamide is effective for initial treatment of childhood intracranial yolk sac tumor. It is necessary, however, to reevaluate the cisplatin dosage and treatment schedule in order to reduce such side effects as bone marrow suppression and renal damage.

Twenty three old male patient was diagnosed as a pineal gland tumor and was operated in neurosurgical ward. He died four weeks later due to pneumonia and respiratory failure. Clinical diagnosis was based on computer tomography (CT) and magnetic resonance image (MRI) examination. Histological study of a biopsy and autopsy specimens showed embryonal carcinoma with yolk sac tumor differentiation. The diagnosis was supported by positive cytokeratin, placental alkaline phosphate and alpha-fetoprotein immunostainings.

Primary germinoma of the central nervous system carries a good prognosis because of their radiosensitivity. Recurrence is rare and extraneural metastases are even more unusual. We report a unique case of a primary intracranial germinoma exhibiting complete response to radiotherapy, but recurring as an intra-abdominal yolk sac tumor. The presence of a VP shunt is thought to have facilitated metastatic spread of the intracranial neoplasm. An 21-year-old (corrected) male was admitted with headache and consciousness disturbance. Computed tomography (CT) revealed an enhanced tumor of the pineal region and hydrocephalus. A ventriculo-peritoneal shunt was emplaced immediately. No serum tumor markers such as alpha-fetoprotein or human chorionic gonadotropin were detectable. A test dose of radiotherapy (whole brain 20Gy) was given. The tumor size was remarkably decreased. Clinical diagnosis was germinoma. Additional whole brain radiation (total 45Gy) and whole spine radiation (20Gy) were given. The tumor and the hydrocephalus regressed completely and the patient returned to school. Three years later, he experienced a feeling of abdominal fullness. CT and echotomography of the abdomen showed a large peritoneal and intra-hepatic tumor. But MRI revealed no recurrent tumor of the pineal lesion or of the other areas in the central nervous system. Radiological and clinical findings showed no tumors in the testis, the retroperitoneal cavity, or the thymus. Laboratory investigation demonstrated elevated serum AFP (26,550 ng/ml). AFP level regressed after combined chemotherapy. However, the patient died due to pneumonia and multiple organ failure. Only needle necropsy was performed. The microscopic appearance of the peritoneal tumor was confirmed to be an endodermal sinus tumor. It was suspected to be a metastasis of the pineal tumor through the V-P shunt system.
