Hormonal changes associated with the use of 15(S)-15-methyl prostaglandin F2alpha in a Silastic device as an abortifacient were evaluated during very early first-trimester pregnancy. Five of six patients aborted completely with drug alone. Measurement of plasma samples demonstrated rapid drug absorption with apparent effective concentrations of 600 to 3000 pg/ml but without a pattern of sustained release and absorption. Routine serial determination of both serum chorionic gonadotropin (hCG) and beta-subunit hCG were used to assess the efficacy of treatment. Although more sensitive, beta-hCG measurement offered no advantage clinically over the standard hCG assay. Plasma progesterone values also reflected success or failure of the technique. Vomiting and diarrhea continue to be problems associated with the use of these compounds. The Silastic device may be the forerunner of a self-administered early abortifacient. Continued efforts are necessary to elucidate mechanisms of action and to find an analog specific for myometrial stimulation.

Use of 16-phenoxy-prostaglandin E2 methane sulfonamide (SH B 286), a prostaglandin E2 derivative, as an abortifacient in 114 patients is reported. Vital signs, intrauterine pressure, and blood levels of steroid hormones, chorionic gonadotropin, and placental lactogen were noted before, during, and after administration. Extraamniotic injection of 100-250 mcg induced abortion in 80% of the 76 women observed. No severe systemic effects occurred, and vomiting (15%), nausea (25%), and uterine cramps (40%) rarely required treatment. Of 38 women receiving an intravenous drip, complete abortion was induced in 33; side effects were dose-dependent and no severe complications were seen. The lowest dose (0.5-1.5 mcg/ml, 1000 mcg total dose) was as effective as larger doses. Uterine contractions were increased by the medication, while serum hormone levels, especially progesterone, decreased. SH B 286 is shown by this study to be an effective and safe abortifacient.

Vaginal suppositories containing 15(S)15-methyl-PGF2alpha-methyl ester (prostaglandin, PG) were tested for legal abortion of pregnancies (36-60 days after last menstrual period) in 42 women; 4 suppositories each containing 1 or 1.5 mg of PG were given every 3 hours. Serum levels of human chorionic gonadotropin (HCG), estradiol-17 beta, and progesterone were measured before and up to 3 weeks after the abortion. Blood loss during, after, and during a menstrual period 2-4 months after the abortion (in 30 women) was determined. Abortion without retention of major products of conception occurred in 93% of the cases. However, 18% of these successful cases had a slow decline in HCG, indicating incomplete expulsion of viable chorionic tissue. Average blood loss was 37 ml during the 1st 24 hours after insertion, with an additional loss of 94 ml in the next 11 days (range, 5-25 days). Heavy blood loss after abortion was significantly related to slow decline in serum HCG. Later menstrual flow was strikingly heavy overall (mean, 74 ml). There was no difference in efficacy or incidence of slow HCG decline between the PG dose of 1 mg and 1.5 mg, but side effects of uterine pain, vomiting, and diarrhea (50% overall, in no case severe) were more marked with the 1.5-mg dose.

We describe our experience with BEP (bleomycin, etoposide, cisplatin) therapy as chemotherapy for testicular tumors in 11 patients. Eight were non-seminomatous testicular cancer patients and 3 were seminoma patients. Three of 8 non-seminomatous testicular cancer patients had no evident metastasis and BEP therapy was performed for prophylaxis of recurrence. Other 5 non-seminomatous testicular cancer patients and 3 seminoma patients had metastatic lesions and BEP therapy was performed to cure these metastatic lesions. Ten of our 11 patients are living and disease-free. One non-seminomatous testicular cancer patient who had brain, lung, eye and bladder metastases and had an extremely elevated human chorionic gonadotropin (hCG) level responded only partially and died later due to disease progression. Side effects in most patients were nausea, vomiting, alopecia and leucopenia and all these side effects were reversible. Neuromuscular toxicity such as paresthesia or abdominal cramp that is sometimes encountered in PVB (cisplatin, vinblastine, bleomycin) therapy was not seen in our patients. Our results support the concept that BEP therapy is better than PVB therapy as an initial chemotherapy for testicular tumors.

In Ohio, a 33-year old woman who had never had an ectopic pregnancy presented at an emergency facility not physically attached to a hospital with abdominal pain over 24 hours which had become more intense during the preceding 4 hours. She did not have vaginal bleeding, diarrhea, vomiting, or pain while urinating. 2 weeks earlier she had a voluntary intrauterine abortion at 8 weeks' gestation. She had intercourse 1 week before coming to the emergency facility. She had widespread tenderness in her abdomen, especially in the lower areas. Blood cell studies suggested an infection. The attending physician presumed her to have pelvic inflammatory disease (PID) as a result of either sexual intercourse or the elective abortion. The physician called for a urinary beta human chorionic gonadotropin test to determine whether placental tissue remained in the uterus. It was positive. 60 minutes after admission, the supine patient's pain increased and her blood pressure dropped to 80/50 mm Hg from 100/60 mm Hg at admission. After administering Ringer's solution, the health team sat her up and she fainted. A repeat cell count indicated sepsis. Her blood pressure decreased to 60 by Doppler and the physician continued to give her fluids and began dopamine. After the team stabilized her, they transferred her to a hospital. Her private physician examined her and then began surgery. The physician found a tubal pregnancy and removed the affected tube and ovary. She recuperated completely. Combined intrauterine and extrauterine pregnancy occurs once in every 30,000 cases. Previous PID, use of ovulation inducing medication, and in vitro fertilization with embryo transfer increases the likelihood of this type of pregnancy occurring. Physicians should consider this possibility if a woman has any of these histories and a combination of abdominal pain, adnexal mass with pain and tenderness, peritoneal irritation, and an enlarged uterus.

Although testes cancer is the most common malignancy affecting young men, dramatic survival rates are now possible with the development of optimal individualised drug therapy. Human chorionic gonadotropin and alpha-fetoprotein are important tumour markers associated with testes cancer, and can provide essential information about prognosis and treatment efficacy. For treatment purposes, testicular germ-cell malignancies are broadly classified as seminomatous or non-seminomatous. Early stage seminomas are treated with radiotherapy, while more advanced disease requires systemic chemotherapy. Stage I nonseminoma patients can now be offered the option of retroperitoneal lymph node dissection (RPLND) or close clinical observation, while patients with stage II or III nonseminoma should generally be treated with chemotherapy. The dramatic survival rates now apparent with chemotherapy are due in large part to the introduction of cisplatin (cisplatinum II)-based chemotherapy and to the optimisation of therapy based on pretreatment risk analysis. The most common chemotherapeutic regimen for standard risk patients includes cisplatin and etoposide (VP 16213) and long term disease-free survival rates exceed 80%. A subset of poor risk patients with significantly reduced survival can be defined. These patients, and patients with relapsed or refractory disease, should receive more aggressive regimens, and ifosfamide (isophosphamide) is proving to be a particularly promising new agent in this regard. High-dose carboplatin with autologous bone marrow rescue is another encouraging alternative currently being investigated for these patients. Chemotherapy, despite substantial effectiveness, is not without toxicity, which consists primarily of myelosuppression, nausea and emesis, and renal toxicity. With careful monitoring and prophylaxis, however, these toxicities can generally be ameliorated or avoided.

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.

A case of extragenital choriocarcinoma which produces human chorionic gonadotropin (HCG) in the small intestine of a 48-yr-old Japanese women is reported. Only seven such cases have been reported. The patient complained of postprandial upper abdominal pain and vomiting of 5 months' duration. Nine years before, right upper lobectomy was performed because of lung undifferentiated carcinoma. Double-contrast examination of the small intestine showed irregular ulceration in the lower jejunum. Celiac angiography demonstrated a hypervascular tumor stain in the branch of the jejunal artery. The serum HCG level was elevated. Gynecological examination revealed nothing abnormal. A small intestinal neoplasm was diagnosed, and a partial resection of the jejunum was performed. Endoscopy on the operating table showed a large, irregularly shaped sessile ulcer. Histologically the tumor was diagnosed as choriocarcinoma, composed of syncytiotrophoblastic cells and cytotrophoblastic cells. Immunohistochemical staining for HCG was positive. No metastasis was present. Although extragenital choriocarcinoma in the small intestine is rare, it should be included in the differential diagnosis of small intestinal neoplasm.

The International Planned Parenthood Federation (IPPF) new statement on the diagnosis of pregnancy was drawn up in April 1990. A pregnancy diagnosis includes clinical evaluation of the woman's history, symptoms, physical examination, and pregnancy tests. Pregnancy symptoms may include amenorrhea, nausea, vomiting, enlargement and tenderness of the breasts, frequent urination, and changes in appetite and food and drink habits. If biochemical testing is not possible, a reliable clinical diagnosis of pregnancy cannot take place before 6-8 weeks. At this time, the clinician can observe cervical softening and uterine softening and enlargement if a woman is pregnant. If the uterine size does not match the length of amenorrhea, clinicians should suspect the following: earlier or later conception than indicated, ectopic pregnancy, incomplete or missed spontaneous abortion, twin gestation, hydatidiform mole, or other uterine anomaly. They should suspect ectopic pregnancy in women with smaller than expected uterine size when they have been sterilized or are using an IUD or are using low-dose progestogen-only pills or Norplant. They should refer women with smaller than expected uterine size who are experiencing bleeding and/or pain to a more sophisticated clinical facility, where an accurate diagnosis of and adequate treatment for ectopic pregnancy can be done. Biochemical pregnancy tests consist of antibodies that mark human chorionic gonadotropin (hCG) from a urine or serum sample. hCG levels increase beginning about 10 days after fertilization. The most convenient and inexpensive pregnancy test for clinics is the immunoassay test (slide test), which requires a urine or serum sample. It can provide reliable results a few days after the missed menstrual period. Clinicians should provide appropriate counseling regardless of whether the client wishes to continue or terminate the pregnancy.

Risk factors for ectopic pregnancy include previous ectopic pregnancy, current intrauterine device use, prior fallopian tube surgery, previous pelvic inflammatory disease and a prior history of infertility. Abdominal pain is the most common symptom, followed by amenorrhea or vaginal bleeding, nausea, vomiting, syncope and dizziness. Referred shoulder pain following the onset of abdominal pain is characteristic of intraperitoneal bleeding and, in the appropriate clinical setting, strongly suggests a ruptured ectopic pregnancy. A coordinated evaluation includes measurement of serum human chorionic gonadotropin concentration and transabdominal or, preferably, transvaginal ultrasonography. Treatment is primarily by one of a variety of surgical techniques. Medical therapy with methotrexate or other drugs is currently under investigation.
