In 50 women without cervical pathology, a SCLH was performed with extraction of the uterus by means of a posterior colpotomy under endoscopic visual guidance. All cases were performed after a diagnosis of dysfunctional uterine bleeding or uterine leiomyomata and treatment with GnRH analogs for 3 months. Uterine fundal measurements ranged from 6-10 cm in greatest diameter. Results, including operating time, blood loss, subjective feelings of nausea, emesis, oral tolerance, and resumption of ambulation were all evaluated in the immediate postoperative period. All patients resumed their normal daily activities at 6 to 10 days postoperatively. A preliminary report addressing sexual function and satisfaction at 3 months postoperatively as compared with the preoperative period was developed. No difference in experience was noted. An economic evaluation was performed at the Clinica Ginemedex that revealed a 30% savings in terms of postoperative care and medication when performing a SCLH as opposed to the more conventional total laparoscopic hysterectomy (LH). SCLH appears to offer several advantages over total LH.

A woman with diagnosis of missed abortion had complications of uterine perforation during dilatation and curettage (D&C). Under laparoscopic guidance the uterus was emptied of the remains of fetal tissue. An opening on the uterus was sutured laparoscopically. There was a superficial tear on the mesosigmoid. The sigmoid colon and the bladder were checked and were intact. Fourteen days after the operation the woman returned complaining of nausea, vomiting, and lower abdominal pain. The diagnosis was obstruction of small intestine. At laparotomy we found a loop of small intestine adhering to the ileum. This was untwisted and the patient was discharged in good condition. The cause of this complication might be trauma to small intestine during D&C that was not diagnosed by laparoscopy, or entry of infected tissue into the peritoneal cavity during D&C. Since the many loops of small intestine make it difficult to check at laparoscopy, it is suggested laparotomy be performed if the surgeon suspects trauma in the intestine.

68-year-old woman presented with abdominal pain and vomiting. After initial conservative therapy, laparotomy showed multiple ulcers of the ileum, one of which had perforated and adhered to the uterus. The affected segment of the ileum was resected. Numerous cytomegalic cells, corresponding to endothelia and macrophages, with intranuclear inclusion bodies, were found in microscopic sections of the ulcerated lesions. These findings were consistent with cytomegalic vasculitis and enteritis. Cytomegalovirus infections of the alimentary tract have been reported mainly in severely immunocompromised patients or those with predisposing disorders such as ulcerative colitis; their prognosis is usually poor. In our patient, there was no obvious immunocompromised state or other gastrointestinal disorders. The postoperative course has been uneventful for 2 years after surgery. The prognosis of Cytomegalovirus-associated lesions in the alimentary tract may be quite good in the immunocompetent patient.

This open multicenter study was performed in 20 hospital gynecological units in the UK. The effects of 600 mg oral mifepristone as pretreatment to vaginal prostaglandin induction of second trimester abortion was studied in 267 women. The primary efficacy variable was the abortion induction interval, defined as the time taken to expel the fetus from the time of administration of the first prostaglandin pessary. Induction was commenced 36 to 48 hours following mifepristone intake. The mean abortion induction interval was 7 h. A total of 81.9% of women aborted within 12 h. There was a significant relationship between abortion induction interval and age of gestation, and a significant inverse relationship between abortion induction interval and parity. Vomiting, pelvic pain, and nausea were the most frequently reported adverse events. Two patients required transfusion and one patient with a uterine scar from a previous cesarean section suffered a ruptured uterus and hysterotomy.

Amonafide demonstrated a poor response rate and substantial toxicity in patients who had measurable, advanced mixed mesodermal tumors of the uterus. Amonafide-a drug that acts through intercalation of tumor DNA-was used to treat 16 patients who had measurable, advanced mixed mesodermal tumors of the uterus as part of a Gynecologic Oncology Group (GOG) Phase II study. The starting dose was 300 mg/m2 intravenously over 1 hour for 5 consecutive days every 3 weeks. Severe or life-threatening hematologic toxicity occurred in 50% of the patients. Two patients experienced vomiting requiring hospitalization. Other toxicities were not severe. One patient had a partial response and one had stable disease, each lasting 4 months. This dose schedule was associated with poor response rate and substantial toxicity.

The use of laparoscopic cholecystectomy in pregnant women has been slow to gain wide acceptance for two reasons: one is the potential for mechanical problems related to the pregnant uterus and the other is fear of fetal injury resulting from instrumentation or the pneumoperitoneum. To assess the effects of laparoscopic cholecystectomy on both the mother and the unborn fetus, we reviewed our surgical experience over a 5-year period analyzing indications for the procedure along with complications and outcome. During this 5-year period, 22 patients ranging in age from 17 to 31 years underwent laparoscopic cholecystectomy during pregnancy. Gestational ages ranged from 5 to 31 weeks with two patients being in the first trimester, 16 in the second, and four in the third. The primary indications for surgical intervention were persistent nausea, vomiting, pain, and inability to eat in 17 patients, acute cholecystitis in three, and choledocholithiasis in two. In all patients a pneumoperitoneum was established by means of a closed technique starting in the right upper quadrant of the abdomen. Two of the 22 patients also underwent successful transcystic common bile duct exploration with removal of common duct stones. All 22 patients survived the surgical procedure without complications, and there were no fetal deaths or premature births related to the procedure. Based on the preceding results, it would appear that laparoscopic cholecystectomy during pregnancy is safe for both the mother and the unborn fetus. Indications for this procedure should include stringent criteria such as unrelenting biliary tract symptoms or the complications of cholelithiasis. If at all possible, when laparoscopic cholecystectomy is indicated, it should be performed either in the second trimester or early in the third.

The purpose of this study was to determine whether intravaginal prostaglandin F2 alpha (PGF2 alpha) would be effective for the treatment of metritis or pyometra in the bitch. Seventeen bitches with metritis or pyometra were treated with PGF2 alpha. Prostaglandin F2 alpha (150 micrograms/kg body weight) was administered once or twice daily by infusing 0.3 ml per 10 kg body wt into the vaginal lumen. Bitches were also treated with amoxicillin (15 mg/kg body wt/48 h) and/or gentamicin (4 mg/kg body wt/day) administered as intramuscular (i.m.) injections. Fifteen bitches were treated successfully with intravaginally administered PGF2 alpha for 3 to 12 days and with intramuscularly administered antibiotics for 4 to 12 days. Success of treatment was judged by cessation of vaginal discharge, the absence of fluid in the uterus as determined by ultrasonography, and the overall health status of the animal. As two bitches with pyometra showed clinical deterioration in spite of medical treatment, ovariohysterectomy was performed after the first and the second treatment, respectively. No side effects (salivation, vomiting, diarrhoea, hyperpnoea, ataxia, urination, anxiety, pupillary dilatation followed by contraction) were observed after PGF2 alpha treatment. The disease did not recur during the subsequent oestrous cycles within 12 months after the initial treatment. The results demonstrate that intravaginal administration of PGF2 alpha was effective in 13 dogs (86.6%) with metritis or pyometra, and caused no side effects. Although the study was based on a relatively small number of cases, it is concluded that prostaglandin F2 alpha can be a useful means of treating bitches with metritis or pyometra. However, in severe cases of pyometra ovariohysterectomy is needed.

Temozolomide (TMZ) is an oral imidazotetrazinone that is spontaneously converted to 5-(3-methyltriazen-1-yl)imidazole-4-carboxamide (MTIC) at physiological pH. MTIC methylates DNA at the O6 position of guanine, although this lesion may be repaired by the enzyme O6-alkylguanine-DNA alkyltransferase (AGAT). In this study, TMZ was combined with cisplatin (CDDP), because both agents have single-agent activity against melanoma and other tumor types. Additionally, CDDP has been shown to inactivate AGAT, and subtherapeutic concentrations of CDDP have been shown to increase the sensitivity of leukemic blasts to TMZ. This Phase I study sought to determine the toxicities, recommended dose, and pharmacological profile of the TMZ/CDDP combination. Patients were treated with oral TMZ daily for 5 consecutive days together with CDDP on day 1 (4 h after TMZ) every 4 weeks at the following TMZ (mg/m2/day)/CDDP (mg/m2) dose levels: 100/75, 150/75, 200/75, and 200/100. Plasma samples were obtained on days 1 and 2 to evaluate the pharmacokinetic parameters of TMZ alone and in combination with CDDP. Fifteen patients received a total of 44 courses of TMZ/CDDP. The principal toxicities of the regimen consisted of neutropenia, thrombocytopenia, nausea, and vomiting, which were intolerable in two of six new patients treated at the 200/100 mg/m2 dose level. Of five patients receiving 17 courses at the next lower dose level (200/75 mg/m2), none experienced dose-limiting toxicity. Antitumor activity was observed in patients with non-small cell lung cancer, squamous cell carcinoma of the tongue, and leiomyosarcoma of the uterus. Pharmacokinetic studies of TMZ revealed the following pertinent parameters (mean +/- SD): time to maximum plasma concentration (Tmax) = 1.1+/-0.6 h (day 1) and 1.7+/-0.9 h (day 2); elimination half-life (t1/2) = 1.74+/-0.22 h (day 1) and 2.35+/-0.70 h (day 2); and clearance (Cl(s)/F) = 115+/-27 ml/min/m2 (day 1) and 141+/-109 ml/min/m2 (day 2). TMZ drug exposure, described by the area under the plasma concentration-time curve (AUCinfinity) and the maximum plasma concentration (Cmax), was similar on days 1 and 2. On the basis of these results, the recommended doses for Phase II clinical trials are TMZ 200 mg/m2/day for 5 days with 75 mg/m2 CDDP on day 1, every 4 weeks. The addition of CDDP did not affect the tolerable dose of single-agent TMZ (200 mg/m2/day x 5 days), nor did it substantially alter the pharmacokinetic behavior of TMZ.

Several pharmacologic agents capable of inducing abortion have become available in the last 20 years. Prostaglandins cause powerful contractions of the uterus that lead eventually to expulsion of the fetal or embryonic tissue, but their effects on smooth muscle elsewhere in the body lead to such troublesome side effects as vomiting and diarrhea. Antimetabolites such as methotrexate inhibit DNA synthesis in rapidly dividing cells such as the trophoblast, resulting in release of prostaglandins and cytokines, extravasation of blood into the decidua, uterine contractions, and expulsion of embryonic or fetal tissue. Drugs that inhibit the synthesis of progesterone (epostane) or block its receptor (mifepristone) reverse the dominant influence of progesterone during pregnancy. As a result, a cascade of events is initiated, including influx of leukocytes and red blood cells into the decidua, release of prostaglandins and cytokines, and uterine contractions. Addition of uterotonic agents such as prostaglandins results in powerful uterine contractions, which supplement those induced by the withdrawal of progesterone. Because these methods reproduce many of the same physiological changes, clinical management of medical abortion is similar to that of spontaneous abortion. These methods provide a useful alternative to surgical abortion in early pregnancy.

An analysis was performed of clinical manifestations and chief diagnostic criteria of progressive tubal pregnancy to allow some judgement about their informative value. The findings secured show the presence of bloody discharges, gnawing pain in the lower area of the abdomen, nausea, vomiting to be of most informative value. In vaginal examination, the following findings can be regarded as main diagnostic criteria: the presence of tumour-like formation in the projection of the adnexa uteri, softening of the uterus sizes. The best supplementary investigatory methods capable of providing relevant information included determination of beta-HG by laboratory means, laparoscopic diagnosis and transvaginal ultrasonography.
