A 20 year old woman with complex partial seizures from childhood developed a stuporous state when her anticonvulsant therapy was substituted by VPA. She recovered when treated orally with clonazepam. This case was compared with others in the literature for which the origin of the stuporous state have been hypothesized.

Methylene chloride is a chlorinated hydrocarbon used widely in home and industry. Its intentional abuse has not been reported previously. We describe the case of a 14-year-old boy who presented with lethargy, nausea, and chills six hours after the intentional inhalation of a household product containing methylene chloride. The patient's elevated carboxyhemoglobin level responded well to 100% oxygen therapy. The pathophysiology and treatment of methylene chloride are discussed.

A 49-year-old woman treated with cimetidine 300 mg tid for more than 18 months for Zollinger-Ellison syndrome experienced lethargy, dizziness, ataxia, and auditory and visual hallucinations after receiving triazolam 0.375 mg hs for sleep. Triazolam plasma concentrations were measured, and a triazolam elimination half-life was calculated to be approximately 8 hours (reported range 1.7-3 h). Cimetidine has been reported to decrease the apparent oral clearance of triazolam, resulting in increased triazolam plasma concentrations with the potential for exaggerated triazolam pharmacologic effects. Cimetidine may have been responsible for the unusually large elimination half-life in this patient. Until the mechanisms and clinical significance of this potential drug interaction are determined, clinicians should use the combination of triazolam and cimetidine with caution.

A 3 year old girl presented with a three week history of lethargy, constipation, and joint swelling. Investigation showed primary hypothyroidism associated with immunological changes including thyroglobulin antibodies. Reassessment several months after beginning thyroxine treatment confirmed persisting hypothyroidism. Primary hypothyroidism may present as a rapid onset disorder.

Primary gastric impaction developed in a pony as a result of the ingestion of persimmon seeds and mesquite beans. Clinical signs included mild abdominal pain, prolonged recumbency, anorexia, and lethargy. When medical therapy was unsuccessful, an exploratory laparotomy was performed. Previously, gastric impaction has been associated with signs of severe abdominal pain. Gastric impaction should be considered in cases of abdominal crisis of long duration and mild pain.

Temazepam is a benzodiazepine derivative indicated for the treatment of insomnia. Pharmacokinetic studies of the hard capsule formulation indicate that the mean time to peak is 2.99 hours and the mean elimination half-life is 14.7 hours. Sleep laboratory studies have demonstrated improvements in all sleep parameters except sleep onset latency. Clinically, patients report improvements in all sleep parameters including sleep onset latency. The efficacy of temazepam compares favorably with barbiturates, glutethimide, nitrazepam, lorazepam, oxazepam, and flurazepam. It has not been compared with diazepam in the clinical setting. Side effects include drowsiness, dizziness, and lethargy. The incidence of hangover effects from 15- and 30-mg doses is relatively low. Temazepam has no proven advantages over other benzodiazepine hypnotics. The major issues that need further clarification include temazepam's sleep induction properties and the relative incidence of hangover and rebound insomnia when compared with longer-acting benzodiazepines.

Acyclovir (ACV) has an ED50 of 0.3 microM against EBV replication in vitro. Based on these and other data we carried out a pilot, double-blind, placebo-controlled trial of ACV for treatment of infectious mononucleosis. Only patients with relatively severe illness requiring hospital management were enrolled. Ten subjects with proven infectious mononucleosis received placebo and 10 ACV. The drug was administered intravenously at 8-hourly intervals in a total daily dosage of 1500 mg/m2 for 5 days. Preliminary analyses of the results indicate that the drug interrupted virus excretion in the oropharynx transiently but had no effect on ability to generate lymphocytic lines from peripheral blood. Symptoms and signs unaffected by ACV were splenomegaly, lymphadenopathy, lethargy, fever and pharyngitis. There was significantly more rapid regain of weight in the ACV-treated group. On the basis of these results we have instituted an out-patient trial of orally administered ACV in patients with less severe illness earlier in its course. We have also begun in-vitro tests of other drugs that might prove to be effective against Epstein-Barr virus infection, and have shown that 9-1 (1,3-dihydroxy-2-propoxymethyl)guanine (BW759) has an ED50 of 0.05 microM.

Eleven academic institutions were selected to study mitoxantrone administered on a schedule of 10 mg/m2/d for five days initially and later at 12 mg/m2/d for five days, each given as a 30 minute intravenous (IV) infusion each day. Patients with acute or chronic leukemia were stratified by leukemic type and clinical status and included one group of patients considered to be in relapse after complete remission from previous chemotherapy and another group of patients considered refractory to standard induction and/or salvage chemotherapy. During the initial treatment schedule, complete remissions were obtained in two of seven patients with acute nonlymphoblastic leukemia, in one of three patients with acute lymphoblastic leukemia, but in none of the patients with chronic granulocytic leukemia in blast crisis. The durations of remission for these three patients were 22, 57, and 78 days, respectively. An increase in mitoxantrone dose to 12 mg/m2/d produced complete remissions in 8 of 19 evaluable patients with acute nonlymphoblastic leukemia, in one of ten patients with refractory acute nonlymphoblastic leukemia, and in one of four patients with chronic granulocytic leukemia in blast crisis. Each of these patients required only a single course of mitoxantrone to achieve remission; the median time to remission was 37 days (range 18 to 64 days). Remission duration ranged from 35 days (chronic granulocytic leukemia) to 186 days, with the median duration for those patients with acute nonlymphoblastic leukemia achieving remission being 135 days. Of the six patients with acute lymphoblastic leukemia, none achieved remission at the higher dose level. Drug-related gastrointestinal toxicity included mucositis (25%), diarrhea (21%), and nausea and vomiting (61%). Systemic infection (nonfatal) was experienced by 21% of patients and alopecia by 17%. Other side effects that occurred occasionally were hepatic dysfunction, decreased renal function, confusion, lethargy, anxiety, and fever. Possible drug-related phlebitis developed in one patient, and a single episode of minor epistaxis was reported in another. Cardiovascular toxicity was low. At a mitoxantrone dose of 10 mg/m2/d for five days, one patient developed hypotension, and one episode of congestive heart failure was reported in another. At the higher dose of 12 mg/m2/d, no drug-related hypotension, congestive heart failure, tachycardia, or chest pain were reported. These data indicate that mitoxantrone is a promising single drug for the treatment of acute nonlymphoblastic leukemia and possibly for acute lymphoblastic leukemia.

The desert ground squirrel Spermophilus tereticaudus is shown to show both reptilian style alphastat regulation and the pH-stat regulation typical of mammalian hibernation, depending upon the range of body temperature and the state of vigilance. Temperature corrected arterial pH and PCO2 of torpid squirrels (Tb 11-28 degrees C) were independent of Tb and about equal to euthermic values at 37 degrees C. Torpid squirrels show a progressive respiratory acidosis as Tb is lowered. In awake heterothermic squirrels (Tb 30-42.5 degrees C), blood acid-base status is like that of many ectothermic vertebrates: from 30 to 40 degrees C delta pHa/delta Tb was -0.0121, delta PaCO2/delta Tb was 1.057 and [HCO3-] remained about constant. Arterial blood from awake heterothermic squirrels measured at standard temperature (37 degrees C) showed no significant change with Tb, similar to blood undergoing anaerobic temperature changes in vitro. In vitro, the delta pH/delta T of blood of constant CCO2 was -0.014. Constant blood pH with change in Tb is thus not a general feature of mammalian acid-base regulation but appears in this species to be a feature of the respiratory and metabolic poise of torpor.

A 9-year-old girl had the insidious development of lethargy, gingival erosions, and follicular hyperkeratosis with perifollicular hemorrhage. A dietary history disclosed that she consumed only one kind of sandwich and beverage and took no other foods. A skin biopsy specimen was consistent with the diagnosis of scurvy, and marked improvement occurred with ascorbic acid therapy. Although it is an uncommon disorder in the United States, scurvy may occur in persons with prolonged and peculiar dietary habits.
