Women undergoing abortion by intraamniotic prostaglandin F2alpha were randomized to receive either prochlorperazine edisylate 10mg, hydroxyzine hydrochloride 100mg, or a placebo every four hours by intramuscular injection in a double-blind fashion. Vomiting was significantly more frequent in the placebo-treated group [0.2 +/- 1.5 SD episodes per patient, n=21] than in the groups treated with prochlorperazine [1.2 +/- 0.5 episodes per patient, n=21] or hydroxyzine [0.3 +/- 0.8 episodes per patient, n=19]. The mean number of merperidine injections in the antiemetic-treated groups was lower than in the control group, but this effect was not statistically significant. There was no significant difference between the treated and the control groups in the interval from prostaglandin treatment to abortion.

A clinical trial comparing 2 vaginal dose schedules of 15(S)15-methyl prostaglandin F2alpha (PGF2alpha) methyl ester (4 or 6 mg) for preoperative dilatation is described. The trial included 28 patients at 8-12 weeks gestation. Vaginal pessaries containing either 1.0 mg (15 patients) or 1.5 mg (13 patients) of the prostaglandin analogue were administered every 3 hours (maximum, 4 doses). The success rates for the 2 groups were 93% and 10% respectively. A 96.4% overall success rate is comparable to that achieved in other studies. 60% of the patients aborted before the planned vacuum aspiration. Minor side effects, primarily vomiting and diarrhea, occurred in approximately 80% of the cases and were more prominent with the higher dose pessary. Since this higher dosage produced an unacceptably high occurrence of gastrointestinal side effects, the lower dosage of 4 mg is preferable. It is concluded that vaginal administration of 15(S)15-methyl PGF2alpha methyl ester is highly effective for preoperative dilatation of the cervix before suction curettage abortion.

In a field study comprising 678 patients with arterial hypertension efficacy and tolerance of the stable combination VKB 105 consisting of 10 mg Pindolol (Visken) and 5 mg Clopamid (Brinaldix) were investigated. Treatment with 1--2 tablets of VKB per day resulted in a successful therapy in 94% of all patients corresponding on the average to a reduction in blood pressure to 145/85 mm Hg within 14 days. In mean arterial pressures ranging between 120 and 170 mm Hg a positive linear relationship between the individual initial value and the hypotensive effect of the combination could be observed. A controlled omission trial disclosed qualitatively the respective contribution to the effect of the two components Pindolol and Clopamid. With a systematic case control of the serum potassium under the combined therapy with VKB 105 and during a monotherapy with Clopamid and antihypokalaemic effect of Pindolol could be demonstrated diminishing the tendency for potassium loss. The result revealed a far-reaching potassium neutrality of diuresis-depending stimulation of renin by the beta-receptor blocker. In 61 patients altogether subjective side-effects could be recorded, such as vertigo (5%), palpitations (2.8%), fatigue (2%), insomina (1.9%), nausea (1.7%) and vomiting (0.8%). Laboratory controls gave no indication for clinically relevant changes.

The effect of ipecac syrup as an emetic in adults as well as children who had ingested antiemetics or other drugs was evaluated. Adults or children over five years of age were given 30 ml of ipecac syrup followed by 360 ml of water; children aged one to five years were given 15 ml ipecac syrup followed by 240 ml of water. If emesis was not induced within 30 minutes, a second dose was administered. Of 232 patients studied (199 adults and 33 children), 188 (81%) vomited following the first dose, 34 (15%) required two doses and seven (3%) did not vomit. Of 63 patients who had ingested drugs with antiemetic properties, 51 (81%) vomited following the first dose, nine (14%) required a second dose and three (5%) did not vomit. The time from ipecac administration to the onset of emesis in all 232 patients averaged 24.2 minutes. Ipecac was successful in inducing rapid emesis in both adults and children who had ingested antiemetics or other drugs, probably as a result of its irritating effect on the gastric mucosa.

Lorazepam 2.5 mg was compared with promethazine 50 mg as oral premedication in a double-blind study in women. The premedication was given at the same time to all patients on each operating list, and both drugs continued to be effective 6 h after ingestion. A similar number of patients considered each drug to have relieved anxiety and the amnesic effect of lorazepam was confirmed. However, the use of lorazepam alone was accompanied by significantly more salivation during and after anaesthesia than the use of promethazine, especially in patients in whom the trachea was intubated. There was also a higher frequency of vomiting during and after operation with lorazepam (seven of 67 patients) than after promethazine (one of 71 patients). Promethazine produced dyskinetic side-effects in six of 71 patients.

The synthesis of 1'-[3-(4-fluorobenzyoyl)propyl]-3-phenylspiro[isobenzofuran-1(3H),4'-piperidine] (2a) and eight halo and methoxy analogues is described. The compounds were generally more potent per os than chlorpromazine in the Sidman avoidance paradigm in rats and less potent than haloperido. 1'-[3-(4-Fluorobenzoyl)propyl]-3-(4-fluorophenyl)spiro[isobenzofuran-1(3H),4'-piperidine] (2e) approached the per os potency of haloperidol in this test and was shown to be active in inhibiting monkey avoidance also. Compound 2e was much less active than haloperidol in antagonizing apomorphine-induced emesis in dogs, apomorphine-induced stereotypy in rats, and amphetamine-induced circling in lesioned rats. This lack of nonselective, dopamine-receptor blocking effects makes 2e attrative as a potential neuroleptic.

After premedication with flunitrazepam=Rohypnol 2 mg orally (2--3 hours preop.) and morphine-atropine (30 min preop.) the patient receives slowly "Ro" i.v. until the phenomenon of volume reduction when speaking is observed. This allows for the smallest possible dosis to achieve sufficient amnesia. After about 20 min the patient becomes responsive again, while his amnesia lasts for about 3 hours more. The cardiovascular functions remain stable with a 25% decrease of systolic blood pressure. Vomiting is reduced. The dry operative field makes microsurgery much easier and improves the final result of the operation. After gaining sufficient experience of the staff, 100% amnesia was achieved in all operations during the last 3 months.

Classic renal tubular acidosis is characterized by a primary defect in establishment of a large hydrogen ion gradient across the distal renal tubule. Thus the development of hyperchlorenic metabolic acidosis follows. In addition, hypokalemia results from renal potassium wasting secondary hyperaldosteronism from sodium wasting and contraction of the extracellular fluid. The presenting signs and symptoms are growth retardation, fatigue, periodic paralysis, polyuria, polydipsia, vomiting and constipation as well as nephrocalcinosis and nephrolithiasis. It is suggested that effective treatment with alkali therapy requires markedly higher doses than formerly recommended, and may related to a higher rate of endogenous acid production from (1) intermediary metabolism of sulfur amino acids and organic acids, (2) impaired tubular reabsorption of bicarbonate and (3) hydrogen ion release from hydroxyapatite formation. It is also suggested that acidosis may interfere with vitamin D metabolism and thus play an important role in the pathoetiology of the growth failure in children with this disorder.

Two infants with lethargy, vomiting, convulsions, coma and marked metabolic acidosis were found to have very high concentrations of methylmalonic acid in their serum and urine. In vitro studies of fibroblasts demonstrated that the infants had different variants of methylmalonic acidemia.Vitamin B(12) was given in two different forms at 1 month of age and at 12 months of age. Each trial continued for 4 months but neither infant showed a clinical or biochemical response.In both infants hyperglycinemia, neutropenia and thrombocytopenia developed during acute metabolic crises only. Hypoglycemia was found in patient 2. Hyperammonemia was severe in patient 2 during acute crises but never appeared in patient 1. When clinically well, both infants continued to excrete abnormal amounts of methylmalonic acid in the urine and both had persistent compensated metabolic acidosis.Marked hyperuricemia developed in patient 1 at 18 months of age and led to progressive renal failure. Allopurinol therapy was necessary to keep the uric acid concentration within the normal range. Renal function returned to normal, as indicated by a marked increase in the renal clearance of creatinine and uric acid.Patient 1 is physically and mentally retarded, and has moderate hypotonia, hepatomegaly and persistent vomiting. Patient 2 has developed normally.The urine concentrations of methylmalonic acid in the four parents were normal.

A female child presented at one year of age with a febrile illness and loose stools, then developed severe ketoacidosis with vomiting; an apparent salicylate level of 11 mg/dl was measured. A sibling had died in similar circumstances nine years earlier. Investigation revealed that the child did not have salicylate intoxication, and that high levels of acetoacetate in blood and urine were giving readings indicative of the presence of salicylate on routine testing. Gas-liquid chromatographic analysis combined with mass spectrometry on urine samples revealed the presence of 2-methyl-acetoacetate, 2-methyl-3-hydroxybutyrate, and tiglyl glycine in appreciable amounts, indicating a defect in isoleucine catabolism located at the beta-ketothiolase step. The oxidation of 14C-isoleucine to CO2 in cultured fibroblasts confirmed that this pathway was defective. We present evidence that beta-ketothiolase deficiency is not simply a defect of isoleucine degradation; the deficient enzyme is the K+ dependent short-chain mitochondrial thiolase, which also plays a major catalytic role in ketone body and fatty acid oxidation.
