A case of intravenous labetalol in the treatment of a resistant hypertensive emergency is reported. Although there have been several reports of the use of oral labetalol in resistant hypertension, no intravenous administration in hypertensive emergency resistant to other drugs has been reported to date. A 36-year-old black female with BP of 270/160 mm Hg with complaints greater than one month's duration of dizziness, severe headaches, blurred vision, shortness of breath, vomiting, palpitations, flushing, agitation, diarrhea, weakness, and weight loss, was treated successfully with intravenous labetalol after she failed to respond to other established parenteral antihypertensive drugs. The patient received labetalol 20 mg iv bolus, and then 20 mg every ten minutes until a cumulative dose of 200 mg was attained. Labetalol produced a prompt but smooth reduction in BP without any reflex tachycardia or other adverse effects. Intravenous labetalol may be safe and effective for the management of rapid BP control in hypertensive emergencies resistant to other parenteral antihypertensive agents.

Sixty out-patients with different nosological types of depression were assigned at random to three different treatment groups and were treated under double-blind conditions for 6 weeks. Two groups received diclofensine in capsules of either 15 or 25 mg, and a third group received capsules with imipramine 25 mg. The dosage schedule provided an initial dose of 2 capsules/day which was to be gradually increased up to a maximum dose of 9 capsules/day. The daily mean dosages actually given over the entire trial period were 64.0 mg diclofensine for group I, 97.6 mg diclofensine for group II, and 102.9 mg imipramine for group III. All treatment groups showed a good improvement of the patients' clinical states within the 6-week period, but the imipramine-treated patients improved more slowly than the diclofensine-treated patients. This was demonstrated by the mean total scores of the Hamilton Depression Rating Scale (HDRS). Evaluation of different factors of the HDRS yielded differences between the two drugs in favour of diclofensine for the factor 'inhibition' from the end of week 1 until the end of week 3 and for the factor 'somatic complaints' during week 3. Side effects were - dose dependently - less frequent, less severe, and lasted shorter in the diclofensine-treated patients than in the imipramine-treated ones. The most frequently reported side effects in the diclofensine-treated patients were dry mouth, insomnia, dizziness, and agitation. In the imipramine group side effects were mainly dry mouth, tremor, dizziness, and sleepiness. In conclusion, this study shows an impressively faster onset of efficacy of diclofensine over imipramine, a finding which should be replicated by further studies.

The effect of sublingual buprenorphine (Temgesic) as a premedicant and for postoperative pain relief compared with morphine/pethidine was studied in 50 patients scheduled for elective surgery of the knee joint. Twenty-five patients received buprenorphine 0.4 mg sublingually 1 h before surgery and the same dose on demand postoperatively. Twenty-five patients were given morphine intramuscularly (7.5 mg or 10 mg to females and males respectively) 1 h preoperatively. This group received pethidine (75 mg) intramuscularly on demand postoperatively. All the patients were anaesthetized with halothane N2O/O2 after induction with thiopentone. No significant differences were found with regard to sedation, dizziness, nausea and vomiting during the study period. Emergence shivering, confusion and restlessness just after termination of the operation were equal in the two groups. In the recovery room, however, there was a higher frequency of shivering (P less than 0.05) in the morphine group. During the first 24 h postoperatively the buprenorphine group was given an average of 3.8 doses compared with 2.3 in the pethidine group (P greater than 0.05). It is concluded, that buprenorphine sublingually is as good as morphine intramuscularly for premedication and therefore should be recommended to patients who wish to avoid injections. For postoperative pain relief the initial dose of buprenorphine should be given intravenously. Only minor and unimportant side effects were seen.

A double-blind crossover study compared the hypnotic effect, daytime carryover, and safety of triazolam 0.5 mg, lorazepam 2 mg, and placebo. The two active drugs were similar in hypnotic effect and superior to placebo. Patients reported more drowsiness upon awakening and more sleepiness in mid-morning and mid-afternoon after nights on lorazepam than nights on triazolam or placebo. The most common side effects--drowsiness, lightheadedness, restlessness, impaired coordination, dizziness, and nausea--were reported three times as often with lorazepam than with triazolam or placebo.

Vaginal suppositories containing (15S)-15-methyl prostaglandin F2 alpha methyl ester were administered to 40 subjects, in an attempt to induce an early abortion. All subjects were 49 days or less from their last menstrual period. Ten subjects received a 3-mg suppository followed in 3 hours by a 1 mg suppository, ten subjects received the 1-mg suppository followed in 3 hours by a 3-mg suppository, and twenty subjects received the 3-mg suppository followed in 1 hour by the 1-mg suppository. Twenty-four subjects (60%) had a successful termination of their pregnancy using the two vaginal prostaglandin suppository regimen. All subjects who aborted had 10 percent or less of their pretreatment levels of beta-hCG 7 to 22 days after therapy. Sixteen subjects (40%) did not abort. One of the subjects who failed treatment refused the second suppository due to gastrointestinal side effects and uterine cramping following the insertion of the 1-mg suppository. A second subject had an incomplete abortion and developed mild endometritis. Sixteen subjects reported side effects which included nausea, emesis, diarrhea, uterine cramping requiring analgesia, restlessness, shakiness, and dizziness. The addition of the second vaginal suppository containing this particular prostaglandin analogue did not significantly increase the overall abortifacient activity of this method.

In a randomized double-blind cross-over trial, the effectiveness of lorcainide at a dosage of three times 100 mg/d by mouth was compared with that of a placebo for the treatment of subjectively disturbing stable ventricular extrasystoles (VES), using 48-hour continuous ECG monitoring. In 11 of 20 patients there was a regression in the VES rate to under 5%, in other 3 patients to under 50% of the initial values. Continuing the treatment, good therapeutic effect was still demonstrable 14 and 28 days later. However, only three patients had no side-effects. The others had sleep disturbances, hot flushes, sweating, restlessness, anxiety, dizziness, hallucinations and gastrointestinal symptoms. Lorcainide thus has a good anti-arrhythmic effect but, because of its side-effects, it should be used only in special circumstances.

In a randomized double-blind parallel group study conducted in three centres the hypotensive activity of piretanide 6 mg b.i.d. was compared with that of hydrochlorothiazide (HCT) 25 mg b.i.d. and HCT 50 mg b.i.d. Ninety-three patients entered the study and sixty-one completed a 16-week trial period. All three treatments produced a significant reduction in supine diastolic and systolic blood pressure after only 2 weeks of active treatment and this was maintained for the duration of the study. The mean maximal reduction in supine diastolic blood pressure was 18% in the piretanide group, 18.8% in the HCT 25 mg b.i.d. group, and 20% in the HCT 50 mg b.i.d. group. The corresponding figures for the percentage of patients attaining a supine diastolic pressure below 95 mm Hg were 83%, 62% and 89%. There were no significant differences between the three groups. Side-effects were generally mild and transient, except for polyuria which was noted in all three groups but more commonly in the piretanide group. Two patients were withdrawn because of side-effects: one patient in the high dose HCT group developed severe postural symptoms; and one patient in the low dose HCT group was withdrawn because of restlessness, nausea, weakness, dizziness and somnolence. All three treatments caused a significant increase in serum uric acid concentrations. Four patients in each of the HCT groups developed hypokalaemia, but no patients in the piretanide group did so.

In a Finnish general practice 120 patients with psychosomatic disorders, manifest as syndromes of tension headache, cardiac neurosis, dizziness or muscular tension, were randomly allocated to treatment over a 4-week period with either flupenthixol (1 to 2 mg per day) or diazepam (5 to 10 mg mg per day). The 4 syndromes and 12 associated symptoms (anxiety, fatigue, depression, pain, asthenia, muscle fatiguability, tension, dyspnoea, restlessness, palpitations, sleep disorders, and vertigo) were rated on a 4-point scale on entry, at 2 weeks and at 4 weeks. Both drugs reduced significantly the average total scores for syndromes and single symptoms after 2-weeks' treatment. Flupenthixol was the more effective in relieving fatigue and vertigo; diazepam in relieving headache, anxiety, tension, restlessness and sleep disturbance. Cardiac neurosis, palpitations and general muscular tension responded poorly to both drugs. After 4 weeks, relief of vertigo, pain and fatigue was more evident in the flupenthixol group, and of anxiety, tension and restlessness in the diazepam group. Side-effects were complained of at some stage by 17 patients in the flupenthixol group (9 of fatigue, 5 of sleep disturbance, 1 of constipation, 1 of extrapyramidal symptoms, and 1 of weight gain) and by 16 patients in the diazepam group (10 of fatigue, 4 of sleep problems and 2 of diarrhoea).

We interviewed and neurologically reexamined 94 patients who had previous pneumococcal meningitis. The findings were allocated into groups with and without a causal relationship to the meningitis. The main sequelae after meningitis were dizziness (23%), tiredness (22%), mild memory deficits (21%), and gait ataxia (18%), whereas other focal neurologic signs were rare. By a rating (0 to 5) of the presence and severity of sequelae after meningitis, 54% of the patients were found to have sequelae. The clinical condition at the time of acute illness was studied in subgroups of patients who had different neurologic sequelae or high sequelae ratings. Gait ataxia was associated with a state of agitation and confusion when the patient was admitted for meningitis. High sequelae ratings on reexamination were associated with an affected consciousness at the acute stage of the disease and with high numbers of WBCs in the CSF at the time of hospitalization.

During the years 1966-1976, 875 patients with bacterial meningitis were treated at the Department of Infectious Diseases, Rigshospitalet, Denmark. In late 1979 and early 1980 a survey by questionnaire was conducted among survivors concerning the impact of the disease. Replies were received from 667 patients (96.4 per cent). The most common complaints after meningitis were headache (32 per cent) inability to concentrate (31 per cent), altered working capability (33 per cent) and loss of memory (24 per cent). Approximately 20 per cent suffered from impaired hearing, visual disturbances and dizziness. Five per cent had convulsions. Each questionnaire was evaluated for sequelae, and when present these were rated as mild, medium or severe. One-third of the patients had sequelae and in 6 per cent these were severe. Sequelae were most commonly associated with drowsiness, coma, agitation and confusion on admission to hospital.
