Intranasal desmopressin represents the treatment of choice in Central Diabetes Insipidus. Nevertheless, this route of administration bears some practical disadvantage, linked to either difficult delivering technique, or the status of nasal mucose. The antidiuretic effectiveness of oral desmopressin has been recently demonstrated, both in experimental animals and in man. In our study we compared oral vs. intranasal desmopressin efficacy in 13 patients affected by Central Diabetes Insipidus. The results show that the peroral administration of Desmopressin at a mean dose of 500-600 micrograms/die determines an antidiuretic effect comparable to that of intranasal route, without affecting body weight, arterial pressure and chemical analysis. Side effects, generally limited to the first week of treatment, were described (nausea, vomiting, headache, dizziness [corrected], bitter taste, epygastralgia, asthenia, epystassis), inducing 4/13 patients to withdrawal the trial.

Migraine is a common condition with, usually, stereotyped symptomatology, suggesting that it is a specific disease entity (a morbus sui generis). However, occasionally a migraine sufferer will exhibit atypical manifestations of the condition; also, some specific diseases such as systemic lupus erythematosus and arteriovenous malformations, may exactly mimic the symptoms of migraine. These latter considerations raise the possibility that migraine is a syndrome rather than a disease. The recent delineation of the trigeminovascular system allows a conception of migraine as being neither disease nor syndrome, but rather a constitutional predisposition of the neurovascular system to react excessively to internal or external stimuli by a pattern of hyperactivity of the brain and of the trigeminovascular apparatus. Activation of the trigeminovascular system, whether by neural impulses from the brain or humoral factors in the circulation, results in vascular headaches, while associated activity in the brain may produce such typically migrainous symptomatology as prodrome and aura, and nonspecific symptoms such as nausea, vomiting and dizziness. In this model specific diseases may gain access to the trigeminovascular apparatus, detonating it to produce vascular headaches and neurological symptomatology which may more or less exactly mimic migraine.

We report a series of 5 representative patients in California who experienced adverse reactions from the illicitly marketed substance gamma-hydroxybutyrate (GHB). The drug is a putative neurotransmitter marketed as a growth hormone releaser for bodybuilders. The most commonly reported symptoms included abrupt drowsiness, dizziness, and a "high". Other effects were headache, nausea, vomiting, myoclonic jerking, and short-term coma. There have been no reported deaths. If product use is discontinued, full recovery with no long-term side effects is universal. No clear dose-response effect was observed; this may be attributable to differences in susceptibility, wide variations in doses taken by the same person, or the coingestion of other substances. Case interviews confirm that, despite being banned by the US Food and Drug Administration, GHB is still widely available in the underground drug market. Athletes and bodybuilders may take drugs for which there are claims of improved performance or body image. Physicians should be alert for signs of GHB poisoning in emergency department and clinic patients.

Forty cancer patients receiving parenteral chemotherapy were assessed for characteristics associated with the development of anticipatory nausea and vomiting (ANV). The patients who developed ANV were more likely to have increased pretreatment anxiety (p less than 0.05), greater posttreatment dizziness/lightheadedness (p less than 0.01), more severe postchemotherapy vomiting (p less than 0.01), and a delayed onset of postchemotherapy nausea and vomiting (PCNV) compared to the patients who developed neither ANV nor PCNV. However, when patients who did not develop PCNV were excluded from the analysis, the difference between the ANV and non-ANV patients remained significant only for postchemotherapy dizziness/lightheadedness (p less than 0.05). In an attempt to identify a group of variables that better predict the development of ANV, we analyzed the data for combinations of variables. Two indices were found to correctly classify ANV and non-ANV patients 71% of the time (p less than 0.05). Index A refers to the presence of at least two of the following variables, pretreatment anxiety, posttreatment dizziness/lightheadedness, and latency of PCNV. Index B refers to the presence of at least two of the following variables: pretreatment anxiety, severity of nausea, and severity of vomiting. The identification of characteristics associated with the development of ANV could lead to new intervention strategies.

The efficacy and safety of oral sumatriptan as a 100-mg dispersible tablet was compared with oral Cafergot (2 mg ergotamine tartrate, 200 mg caffeine) in a multicentre, randomized, double-blind, double-dummy, parallel-group trial. In the trial, 580 patients were treated from 47 investigating centres in nine European countries. Sumatriptan was significantly more effective than Cafergot at reducing the intensity of headache from severe or moderate to mild or none; 66% (145/220) of those treated with sumatriptan improved in this way by 2 h, compared with 48% (118/246) of those treated with Cafergot (p less than 0.001). The onset of headache resolution was more rapid with sumatriptan, whereas recurrence of migraine headache within 48 h was lower with Cafergot. Sumatriptan was also significantly more effective at reducing the incidence of nausea (p less than 0.001), vomiting (p less than 0.01) and photophobia/phonophobia (p less than 0.001) 2 h after treatment, and fewer patients on sumatriptan (24%) than on Cafergot (44%, p less than 0.001) required other medication after 2 h. The overall incidence of patients reporting adverse events was 45% after sumatriptan and 39% after Cafergot; the difference was not significant. The most commonly reported events in the sumatriptan-treated patients were malaise or fatigue and bad taste; these were generally mild and transient. Nausea and/or vomiting, abdominal discomfort, and dizziness or vertigo were reported by a greater proportion of Cafergot-treated patients. It is concluded that oral sumatriptan was well tolerated and is a more effective acute treatment for migraine than Cafergot.

Halofantrine has been given to 14 children and 15 adults suffering from an acute attack of P. falciparum malaria and living in Dakar (Senegal) to a total dose of 24 mg/kg/body weight for the first group and 1,500 mg for the second in 3 times at 6-hourly intervals. This treatment has allowed the fever to clear in all cases within 36.3 +/- 19.9 hours and headache to disappear at D3 in 93.1% of cases. A reduction by 93.6% of the average parasite density which amounted before treatment to 27,710 trophozoites/mm3 of blood has been recorded from the day following the beginning of treatment and the parasite clearance obtained in all the patients of whom had chloroquine-resistant P. falciparum strains in mean time of 58.0 +/- 14.7 hours. In 3 cases (10.7%) a recrudescence of parasitemia has been noticed in D14. Only 1 of them was treated again with halofantrine which proved efficient from D2. The only adverse reactions have been nausea, vomiting, a slight diarrhoea and dizziness which affected only 13.8% of the patients. No abnormality has been noticed at a biological level. These results confirm the efficacy and good tolerance of halofantrine and allow to list it among the resource drugs used for the treatment of chloroquine-resistant P. falciparum malaria in our area.

Fifty-four patients with advanced malignancies were treated on this phase I trial of coumarin and cimetidine. The dose of coumarin was escalated, with three patients treated at each dose level, while the cimetidine dose was held constant at 300 mg four times daily. Patients received coumarin alone as a single daily oral dose for 14 days; on day 15, cimetidine was added and both drugs were continued until progression of disease. This trial was initiated with patients receiving coumarin at 400 mg daily and closed at 7 g daily with four of five patients on this dose experiencing nausea and vomiting. Treatment was generally well tolerated over a wide range of coumarin doses. Symptomatic side effects were few, mild, and usually self limited. Side effects included insomnia, nausea, vomiting, diarrhea, and dizziness. Two patients withdrew from therapy because of daily nausea and vomiting. Typically, nausea, vomiting, and dizziness occurred 2.5-3 hours after a dose of coumarin. In most patients, these side effects abated spontaneously with continuation of therapy. There was no significant hematologic or renal toxicity. Hepatotoxicity occurred in only one patient and was manifested by asymptomatic abnormal elevations of serum hepatic transaminases. This toxicity was reversible upon interruption of therapy. Objective tumor regressions were observed in six patients with renal cell carcinoma. Responses occurred at coumarin doses ranging from 600 mg to 5 g daily. Coumarin is a relatively nontoxic, oral, outpatient therapy that warrants further investigations for the treatment of human malignancies. Because of its low toxicity, there is potential for combining coumarin with chemotherapeutic and/or biological agents in an attempt to improve on efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)

Asymptomatic schoolchildren in Guinea Bissau were given approximately 10 mg of quinine/kg body weight once daily during 5 days (n = 15) or 3 days (n = 16) for treatment of P. falciparum. Five children had parasitemia on the seventh day of follow up. Adverse reactions were reported by 12 children during treatment, mainly mild tinnitus, dizziness and vomiting. Single daily doses were less effective than the divided doses previously used by us for the same short time period and also associated with more frequent adverse events.

Sixteen patients acutely poisoned with aldrin were examined to evaluate a possible correlation between serum aldrin and dieldrin levels and clinical complaints. The patients were classified as having mild (N = 8), moderate (N = 5) or severe (N = 3) poisoning according to clinical symptoms. Concentrations of less than 20 micrograms/l were usually associated with mild poisoning, which involved complaints such as nausea, vomiting and epigastric pain, whereas concentrations of 100 to 200 micrograms/l were considered to represent moderate intoxication and were associated with nausea, vomiting, epigastric pain, headache, dizziness, and convulsions. Severe or fatal cases were associated with levels above 700 micrograms/l. Taken together, these results suggest that serum aldrin and dieldrin levels can be used as indicators of clinical prognosis after acute poisoning with these insecticides and that convulsions could suddenly occur even in the absence of prodromal signs or symptoms.

The large number of antidepressants available provides a wide range of choice. While clinical effectiveness is the most important consideration, toxicity in overdose must be considered in the risk-benefit assessment of each antidepressant. There are almost 300 deaths each year in Britain from tricyclic overdose, and very few deaths from newer antidepressants. Fluvoxamine appears to have low toxicity in overdose. Symptoms are often minimal: nausea, vomiting, dizziness and somnolence. There is one reported case of prolonged cerebral depression after ingestion of 5.5 g. Overdoses of up to 9 g have produced minimal symptoms and full recovery. No deaths from overdose with fluvoxamine alone have been reported in the literature, although one death certificate in Britain has mentioned fluvoxamine as the cause of death. Fluvoxamine appears to be a valuable alternative to the tricyclic antidepressants, and has a high margin of safety in overdose.
