A 3-yr-old boy was investigated for numerous episodes of fatigue, irritability, pallor, and sweating, which began at 11 mo of age, when he had an episode of symptomatic hypoglycemia with ketonuria. He had euphoria, mental confusion, drowsiness, nausea, and vomiting 1-5 hr after oral administration of glycerol in doses of 0.5-1.0gm/kg. Orally administered MCT (1 gm/kg) had similar effects. On one occasion, oral glycerol also provoked hypoglycemia, as had a 16 1/2 hr fast. Intravenously administered glycerol (0.09 gm/kg) induced an immediate loss of consciousness from which he recovered spontaneously after 30 min; there were no changes in blood glucose values. Intravenously administered fructose (0.25 gm/kg) was tolerated normally. Leukocytes showed normal activities for FDPase, glycerol kinase, and glycerol phosphate dehydrogenase. The restriction of dietary intake of fat has been associated with a marked improvement in physical and mental activities. These observations suggest a unique, yet undifined intolerance to glycerol, which suggest caution in the diagnostic use of glycerol in the investigation of hypoglycemia as well as in the therapy of increased intracranial or intraocular pressure.

The effect of guancydine (1-cyano-3-tert-amylguanidine) on systemic and renal hemodynamics was studied in nine patients with arterial hypertension. Antihypertensive drugs were withheld for 15 days before beginning the investigation. Average sodium intake was 105 meq/24 hours in some patients and 25 meq/24 hours in others. Patients received placebo during a control period that averaged 14 days. Guancydine was given for 7 to 18 days at an average dose of 21 mg/kg of body weight. Although mean arterial blood pressure decreased significantly in all patients, it reached normal levels in only two. There was no change in cardiac output. Glomerular filtration rate and renal plasma flow remained unchanged, whereas urinary sodium excretion diminished, suggesting an activation of the renin-angiotensin-aldosterone system. A substantial gain in body weight was noted. Nausea, vomiting, constipation, somnolence, restlessness, mental confusion, asthenia, and urine retention were observed. The anti-angiotensin effect of guancydine that has been described in animals was not observed.

In this double-blind study, haloperidol (n = 15) and thiothixene (n = 15), administered parenterally in emergency rooms and outpatient facilities to 30 acutely excited, agitated psychotic patients in hourly doses of 4 mg. or 8 mg., as needed over a four-hour period (total dosage ranging from 4 to 32 mg.), achieved rapid tranquilization in 30 patients. Significant improvement was shown over a six-hour period on BPRS Total Score, the four factors--Thinking Disorder, Anergic state, Excitement and Disorientation, and Depression and also on hourly ratings of 17 symptoms of a Psychiatric Target Symptom Profile. No significant differences were found between the haloperidol-treated and thiothixene-treated groups. Few adverse reactions were noted, all of them mild, the most frequent being drowsiness in six patients.

The Brompton mixture is widely used as an effective method for controlling pain in cancer patients. In a double-blind crossover trial a standard Brompton mixture containing morphine, cocaine, ethyl alcohol, syrup BP and chloroform water was compared with morphine alone in a flavoured aqueous solution; both were administered orally. Pain was measured by means of the pain intensity index of the McGill Pain Questionnaire. Ratings of confusion, nausea and drowsiness were obtained from both the patients and their nurses and relatives. The data showed that there was no significant difference between the Brompton mixture and morphine administered orally for any of the variables. Both relieved pain effectively in about 85% of the patients.

Ftorafur is a 5-fluorouracil analogue which is slowly metabolized to 5-FU, resulting in prolonged therapeutic levels of this latter drug. Ninety-one evaluable patients with metastatic breast cancer were treated with Ftorafur, Adriamycin, cyclophosphamide, and BCG (ACFTOR-BCG), in an attempt to increase the effectiveness of the program or decrease its myelosuppressive toxicity. The results of this trial were compared to those previously reported with the combination of 5-FU, Adriamycin, cyclophosphamide, and BCG (FAC-BCG). Overall objective response rates were 65% and 76% for ACFTOR-BCG and FAC-BCG, respectively. Durations of response were 12 months and 14 months for ACFTOR-BCG and FAC-BCG (p = 0.53). The median survival of responders was 22 and 23.9 months, respectively. Substantial toxicity was observed with Ftorafur: nausea and vomiting severe enough to cause weight loss was observed in a substantially higher fraction of the patients treated with this drug than with 5-FU. Other side-effects, which were not observed with the 5-FU combination, were somnolence, dizziness, personality changes, tremor, ataxia, and confusion. No differences in myelosuppressive toxicity were observed between the two combinations, and the incidence of infectious complications was identical. The combination of Ftorafur, Adriamycin, cyclophosphamide and BCG did not offer any advantages with respect to increased effectiveness or reduced toxicity over the FAC-BCG regimen in breast carcinoma.

An analysis of seven sporadic cases of Legionnaires' disease confirmed clinical features recorded during epidemics and identified aspects of the illness either unreported or not emphasized. Four patients had central nervous system abnormalities. Mental status changes included somnolence, obtundation, delirium, disorientation, and confusion. Three patients experienced visual hallucinations, and one patient without pneumonia had a grand mal seizure with residual memory deficit. Two patients had disseminated intravascular coagulation with thrombocytopenia, elevated split fibrin products, and prolonged partial thromboplastin and prothrombin times. Four patients had severe hypoxia; one patient had an exudative pleuritis. One patient whose treatment included erythromycin had radiologic improvement of his pneumonia despite deteriorating ventilatory function that led to death. The concept of Legionnaires' disease as a severe, diagnostically perplexing pneumonic illness is valid but too narrow. The emerging spectrum is that of a multisystem disease that, besides the lungs, often involves the central nervous system and can be accompanied by disseminated intravascular coagulation.

A phase II evaluation of anguidine was carried out in 30 patients with advanced refractory breast cancer. A dose of 5.0 mg/m2 daily for 5 days was explored. The main toxic effects were nausea and vomiting, fever and chills, hypotension, skin erythema, somnolence, confusion, and lethargy. Myelosuppression was minimal. Among these extensively pretreated patients, there was one partial responder and one additional patient who showed improvement (less than a partial response); both responses occurred in soft tissue sites.

Acetazolamide has been formulated in a new gastrointestinal therapeutic system that delivers the drug at an essentially constant rate of 15 mg/hr (GITS 15/125). We compared the therapeutic effect, magnitude of plasma concentration fluctuations, and incidence of side effects produced by the GITS 15/125 with conventional 250-mg acetazolamide tablets on eight glaucomatous patients randomly assigned to a different regimen each week. One or two GITS 15/125 twice a day (bid) were found as effective in reducing intraocular pressure as one 250-mg acetazolamide tablet. Plasma concentration fluctuations with the GITS 15/125 were decreased, compared with acetazolamide tablets, and, as a result, the incidence of drowsiness, tingling feet, tingling hands, and confusion was substantially reduced.

The suitability of Althesin as a short-acting anaesthetic agent was studied by comparing it to methohexitone. Twenty-eight anaestheias were given using equipotent doses of the two anaesthetics in order to anaesthetize 14 patients once with each drug. Thus the patients served as their own controls. Sleep induced by Althesin averaged 7 minutes, which was slightly but not statistically significantly longer than that produced by methohexitone (average 6 minutes). The time taken until orientation of the patients was complete was considerably longer with Althesin than with methohexitone. The responses to Althesin had a much wider range of individual variation in induction time, duration of anaesthesia and orientation time. After Althesin, three patients displayed mental confusion with anxiety on awakening. The recovery from anaesthesia was assessed by several recovery tests and observations, in addition to the patients' subjective assessments. Drowsiness was more manifest and persisted longer following Althesin than after methohexitone. Ninety minutes after anaesthesia, a tendency to collapse on standing was obvious following methohexitone, but this was not seen after Althesin. The level of test values and the physical status of the patients returned to pre-anaesthetic levels within 2 hours after both agents. The majority of the patients found anaesthesia with both compounds pleasant. However, they seemed to favour methohexitone as regards pleasantness and their subjective impression was of faster awakening or less postanaesthetic drowsiness.

In a controlled clinical investigation based on ten patients with simple absences and ten patients with myoclonic atonic seizures, all patients who had insufficient response to conventional antiepileptic treatment received clonazepam (Rivotril [Denmark]; Clonopin, comparable US product) combined with previous antiepileptic drugs. The effects of the combined use of clonazepam and the previous antiepileptid drugs were compared with the effects of placebo combined with the same drugs. The trial was single-blind crossover with sequential analysis. In a daily dose of usually 3 to 6 mg, depending on patient age, the antiepileptic effect of clonazepam was significantly superior to placebo and was estimated as remarkably good. Side-effects of somnolence, fatigue, drowsiness, and coordination disturbances occurred in most of the patients, but subsided spontaneously or could be controlled by slow increase or slight reduction of dosage. Mental sideeffects such as agitation, confusion, and aggressiveness were more troublesome and caused discontinuation of clonazepam in two patients.
