he safety and efficacy of oral transmucosal fentanyl citrate (OTFC) as a preanesthetic medication and the efficacy of droperidol as a prophylactic anti-emetic were evaluated in 100 children aged 2-8 yr undergoing general anesthesia for outpatient surgery. Patients were randomly assigned to one of four groups and managed in a double-blinded manner: 1) placebo lozenge 45 min preoperatively and placebo (normal saline) injected intravenously after induction of anesthesia; 2) placebo lozenge 45 min preoperatively and 50 micrograms/kg droperidol intravenously after induction; 3) 15-20 micrograms/kg OTFC lozenge 45 min preoperatively and placebo intravenously after induction; and 4) 15-20 micrograms/kg OTFC lozenge 45 min preoperatively and droperidol 50 micrograms/kg intravenously after induction. Anesthesia was induced and maintained with halothane and nitrous oxide in oxygen. Heart rate, respiratory rate, blood pressure, and hemoglobin oxygen saturation (SpO2) were monitored throughout the study. Scoring systems were used to evaluate sedation, anxiety, cooperation, and ease and quality of anesthetic induction. Emergence, recovery, and discharge times were recorded. Nausea, vomiting, and adverse effects were noted. Preoperatively, children receiving OTFC had significantly greater sedation, slower respiratory rates, lower SpO2, and less excitement during induction. Postoperative nausea and vomiting occurred significantly more frequently after OTFC than after placebo. Prophylactic droperidol did not significantly reduce the incidence of nausea and vomiting. The authors conclude that, in pediatric surgical outpatients, OTFC reliably induces preoperative sedation and facilitates inhalation induction of anesthesia, but it is associated with significant decreases in respiratory rate and SpO2 and a high incidence of postoperative nausea and vomiting that is not significantly reduced by prophylactic droperidol.

A review is given of the various methods of assessing carbohydrate tolerance in pregnancy. Oral glucose tolerance screening and diagnostic tests have been in use for more than 25 years. They are easily administered, relatively inexpensive, and present reasonable sensitivity; therefore, they continue to be used quite extensively. However, lack of reproducibility of the results and side effects such as nausea, vomiting, and headache have led to the use of alternate methods including glucose polymer (Polycose) and standard breakfast meals. These methods have been reported to present satisfactory results in clinical practice. Glycosylated hemoglobin (HbA1c) and fructosamine assays are also alternate forms of testing carbohydrate metabolism HbA1c measurement have been proven insensitive as a screening test for gestational diabetes, while their use as an index of overall glucose control remains valuable. The role of fructosamine in the assessment of carbohydrate intolerance remains controversial with conflicting claims made by various investigators regarding its sensitivity in detecting gestational diabetes and its response to alterations in glycemic control. In this review, the relative advantages and disadvantages of each glucose tolerance test are discussed and recommendations are given regarding their utility in pregnancy.

A patient presented without symptoms 30 minutes after ingesting acetonitrile, also known as methylacyanide. He had prompt gastric lavage and activated charcoal administration. Hours later, the onset of clinical toxicity was heralded by mental status abnormalities and vomiting prior to a generalized seizure. Following administration of sodium thiosulfate, the patient made an uneventful recovery. A blood cyanide level drawn shortly after presentation, but reported after the patient had been discharged, documented significant exposure. During hospitalization, cyanide toxicity was inferred from the history of ingestion of acetonitrile, plus a significant absence of venous blood hemoglobin desaturation. Because even small amounts can be harmful and toxicity is delayed, all acetonitrile ingestions should be presumed dangerous. Patients should be observed and repeatedly evaluated for at least 24 hours. In the absence of cyanide level determinations, lethargy, vomiting, seizures, and the lack of normal venous blood hemoglobin desaturation are clues to cyanide toxicity.

Patients (n = 104) were judged to be thiamine deficient by the criteria of erythrocyte transketolase activity (ETK) less than 0.6 U/g of hemoglobin, or greater than 17% increase in this activity on addition of thiamine pyrophosphate in vitro (TPP effect). ETK activated by TPP in vitro (AETK) was related to ETK by a linear regression of slope greater than or equal to 1, implying that transketolose apoenzyme (apoTK) was constant or decreased as ETK decreased. For most patient groups the value of apoTK was 0.1 U/g and the slope 1.033 to 1.050. In the subgroup of non-vomiting drinkers with Wernicke's encephalopathy (WE), the slope of the linear regression of AETK on ETK was 1.21, so that apoTK decreased as ETK decreased. Comparison of these data is consistent with a difference in the TK of WE drinkers from that of others. Generally, any variation of TPP effect was due only to variation of ETK. We recommend measurement of ETK, without TPP effect, for the assessment of thiamine nutrition.

This is a report on 912 patients treated during 1973 to 1979 for pulmonary tuberculosis and/or extrapulmonary organ involvement. These patients had been treated with a fixed tablet combination of isoniacide, prothionamide and diaphenyl sulfone in association with rifampicin and partly other substances. It was the aim of our study to examine this form of therapy in respect of side effects and effectivity. 535 of these 912 patients were followed up for as long as 13 years (maximum follow-up period). According to the criteria of the American Tuberculosis and Respiratory Diseases Association the patients were suffering from 182 cases of pulmonary tuberculosis of only slight extension, 490 of moderate extension and 130 of large extension, as well as 55 cases of pleuritis, 67 extrapulmonary organ tuberculoses and 1 tuberculosis of the bronchial mucosa. Allergic skin reactions occurred in 0.7% of the cases, and in 0.9% there were neurological disturbances such as vertigo, paroxysms and polyneuropathies. In 7.4% of the patients there was an increase in serum enzyme activities of SGOT, SGPT, Y-GT as a sign of hepatotoxicity. In 5.5% of the patients there were several gastrointestinal concomitant phenomena such as sensation of fullness, nausea, and vomiting. Under IPD therapy the hemoglobin valuedropped on the average by 12% up to the 5th or 6th week of treatment and rose subsequently to almost normal levels. No permanent damage was seen in any of the patients under observation. In the moderately extended tuberculosis cases disinfection occurred on the average between the 6th and 8th week of treatment, in the greatly extended cases on the average in the 9th to 13th week.(ABSTRACT TRUNCATED AT 250 WORDS)

cis-Diamminedichloroplatinum(II) (CDDP) was given as a single agent at a dose of 25 mg/m2 daily for 5 days by continuous infusion; treatment was repeated every 4 weeks in 30 previously untreated patients with advanced non-small-cell lung cancer (NSCLC). The median age of the patients was 61 years; 13 patients had limited disease and 17, extensive disease. The overall response rate was 40% (12/30; 95% confidence limits, 23-58%), with a median survival of 8 months. Vomiting was observed in 37% of patients; elevated serum creatinine levels (greater than 1.5 mg/dl), in 7%; leukopenia (less than 3,000/mm3), in 39%; thrombocytopenia (less than 70,000/mm3), in 26%; and anemia (hemoglobin less than 9.5 g/dl), in 60% of patients. In all cases, these toxicities were mild and transient, requiring no dose modification. The exposure to filterable platinum, determined from the area under the concentration-time curve, was 9.08 +/- 3.21 micrograms h ml-1. We conclude that CDDP given by 5-day continuous i.v. infusion is safe and effective for treatment of NSCLC.

We describe a 22-month-old boy with iron deficiency anemia and reactive thrombocytosis who developed vomiting, headache, mental status changes, and seizures. Computed tomography showed infarction of the basal ganglia and thalami. Magnetic resonance imaging revealed cerebral venous thrombosis, delineated the extent of the vascular and associated parenchymal involvement, showed the infarcts to be hemorrhagic (a finding not imaged by computed tomography due to our patient's depressed hemoglobin level), and obviated the need for invasive angiography.

A 41-year-old female, who had been diagnosed as having paroxysmal nocturnal hemoglobinuria (PNH) in 1985, was admitted to our hospital with cough, fever, diarrhea, vomiting and palpitation in April 1988. The chest X-ray showed pneumonia in her right lung. In the peripheral blood, red blood cell count was 1.64 x 10(6)/microliters, hemoglobin 4.7 g/dl and reticulocytes 19%. The levels of serum LDH, indirect bilirubin and creatinine were high. Pneumonia improved by the administration of antibiotics, however, anemia and renal failure deteriorated. After washed red blood cell transfusions totalling 2,000 ml and six times of hemodialysis, renal function returned to normal. This patient with PNH appeared to have developed acute renal failure by dehydration and hemolytic crisis due to pneumonia.

The indication of a chemotherapy is advisable with patients who are suffering from a progressively metastasised, secondarily hormone refractory carcinoma of the prostate. In search of efficient chemotherapy protocols we combined cisplatin with epirubicin (PE scheme) in our clinic. Massive side effects of that aggressive chemotherapy scheme like gastro-intestinal trouble and myelotoxicity are the limiting factors of the scheme. With measures like reducing the dosage, delaying the next cycle, or breaking off the therapy the effective dosage can often not be achieved. The anti-emetics which are usually used today exclusively give anti-emetic protection. The additional administration of xenogenic peptides (Factor AF2) had additionally myeloprotective effect in former studies. In this study we examined whether, by additionally giving Factor AF2, the patients' subjective condition, and above all their hemogram, could be stabilised in order to achieve the effective dosage or dosage intensity. For that, the patients were prospectively randomised in two groups by means of a random selection board. The analysis of the data gained in the protocol showed that the additional administration of Factor AF2 improves the patients' subjective conditions significantly. Apart from that, we noticed a considerable reduction of the vomiting frequency. Concerning the objective measured parameters of the leukocytes, thrombocytes, erythrocytes, and the hemoglobin level, the significantly myeloprotective effect of Factor AF2 could be proved. Due to the fact that in the verum group there were considerably fewer cases of breaking off or delays of the treatment than in the control group, the effective dosage intensity could be achieved with a higher number of patients in that group.

The antiprogestin RU 486 (mifepristone) has been shown to induce abortion when administered in early pregnancy, but the rate of incomplete abortion is high, around 40%. As blockage of the progesterone receptor increases the myometrial sensitivity to prostaglandins, a combination of RU 486 and a prostaglandin E2-analogue was tested for termination of pregnancy. One hundred and sixteen women, with a gestational length of less than 49 days from the first day of the last menstrual period, were treated with a daily dose of 50 or 100 mg RU 486 for 3 to 6 days, complemented with an intramuscular dose of 0.25 mg sulprostone (16-phenoxy-PGE2-sulfonylamide) on the last day of RU 486 treatment. The results confirmed that a reduction of treatment duration to 3 days is just as effective for inducing abortion (91% complete abortion) as a 4-6-day treatment regimen (95% complete abortion). Six patients had an incomplete abortion and in one the pregnancy continued unaffected. Side effects included intense uterine pain after the prostaglandin administration (16%), vomiting associated with the antiprogestin intake (9%) and after the prostaglandin administration (9%). One woman needed emergency curettage due to heavy bleeding. Six percent of the treated patients had a decrease in hemoglobin exceeding 20 g/l during the first week but no patient needed blood transfusion. No serious side effects were recorded.
