This study was conducted to determine whether intravenous theophylline, added to inhaled albuterol and intravenous methylprednisolone, provides a clinically significant benefit in the treatment of pediatric status asthmaticus. Patients aged 2 to 10 years were randomized to receive either intravenous theophylline or placebo. All patients received aerosolized albuterol and intravenous methylprednisolone. There was no difference between groups in the improvement of a clinical asthma score over time, in oxygen requirement, or in the number of albuterol treatments required. Theophylline group patients experienced more nausea, emesis, and insomnia. We conclude that there is no benefit in adding theophylline to treatment with methylprednisolone and albuterol for pediatric status asthmaticus. Furthermore, there are significantly more adverse effects associated with the use of theophylline.

The new immunosuppressive agent FK506 was used with steroids to treat 22 pediatric patients who received living-related partial liver transplantation. Seventeen recipients survived and 5 died between one and 16 months after transplantation. Three of the 5 patients who died had required intensive care preoperatively. Autopsy findings showed no evidence of rejection. There was no episode of rejection that required retransplantation in any of the patients. Liver allograft dysfunction, which was suspected to be a rejection response, was encountered in 2 recipients with ABO-nonidentical but compatible grafts. However, their clinical and biochemical findings were ameliorated upon steroid pulse therapy or upon augmented FK506 administration without additional potent immunosuppressive agents. Steroid treatment has been discontinued in all surviving patients at 1-9 months after transplantation. Infectious complications encountered in 9 patients included 2 bacterial, 5 viral, and 2 fungal infections. One recipient died of fungal pneumonia. Abnormal increase of serum creatinine level was confined to the complicated patients. Hypertension was a temporary adverse reaction in the early postoperative period, and only one patient needed an antihypertensive drug at 2 months after transplantation. Acute pancreatitis with hyperamylasemia was observed in one patient who was treated successfully with reduction of FK506 administration. Tremor was observed in 8 patients, itching in 4, insomnia in 2, and vomiting in one. Hirsutism, gingival hypertrophy, and lymphoma were not observed. FK506 was highly effective in living-related partial liver transplantation not only in terms of immunosuppressive potential but also because it produced fewer adverse effects.

Felbamate is currently being developed as an antiepileptic agent. Although its mechanism of action has yet to be fully elucidated, felbamate appears to inhibit both the spread of seizures and increase seizure threshold in animal models. Data available in the clinical setting provide evidence that, at doses of up to 3600 mg/day as an adjunct to existing antiepileptic therapy or as monotherapy following substitution for other medications, the drug reduces the frequency of partial onset seizures in adult patients refractory to conventional antiepileptic treatments. Felbamate is also effective in the treatment of Lennox-Gastaut syndrome in children, a severe epilepsy which is usually refractory to antiepileptic agents. The effect of felbamate in the treatment of generalised tonic-clonic seizures in adults with partial onset seizures which are secondarily generalised is promising but requires clarification in large-scale trials. The most common adverse effects occurring during administration of felbamate are mild to moderate gastrointestinal (nausea, vomiting and anorexia) and central nervous system (headache, somnolence, diplopia, dizziness and insomnia) disturbances. Drug interactions with other antiepileptic agents may prove problematic in terms of adverse effects. Thus, at this stage of its development, the antiepileptic efficacy of felbamate in treatment-refractory patients with partial onset seizures and Lennox-Gastaut syndrome has been proven but efficacy in generalised tonic-clonic seizures requires further substantiation in large well controlled and well designed clinical trials. In addition, a more comprehensive base of comparative clinical trials data is necessary to further clarify issues of relative efficacy and tolerability compared with other antiepileptic agents. The clinical implications of the drug interactions associated with felbamate also require more detailed investigation. These data will be awaited with interest and when available will help to place felbamate in perspective in the management of epilepsy.

According to the hypothesis implying that the main mechanism underlying opiate addiction is the blockade by opiates of NMDA receptor functions and subsequent upregulation and supersensitivity of the receptors, noncompetitive NMDA receptor blocker dextromethorphan (DM) has been successfully used in the heroin addict treatment. As the stimulation of NMDA receptors modulates the release of neurotransmitters and hormones such as NE, D, ACh, GH, LH, LSH, ACTH etc., all of which have been found responsible for the manifestation of abstinence syndrome signs including craving and neuronal death by excessive stimulation of NMDA receptors, the incomplete blockade of the NMDA receptors minimizes the intensity of the abstinence syndrome and provides the downregulation of the receptors. In the present study, tizanidine (TIZ), which inhibits the release of endogenous excitatory aminoacids by the agonistic activity on alpha 2-adrenoreceptors, was combined with DM to obtain further benefits. Forty-four male and three female heroin addicts were the subjects of the study. Their daily mean heroin intake was about 2.28 g street heroin. The main duration of heroin use was approximately 3.4 years. Two to three hours after abrupt withdrawal, the outpatients were given 15 mg DM every hour, 25 or 50 mg chlorpromazine (CPZ) + 4 mg TIZ every six hours and 10 mg diazepam + 10 mg hyoscine N-butyl Br + 250 mg dipyrone every six hours three hours following CPZ. The addicts were controlled twice a day. Yawning, rhinorrhea, perspiration, piloerection, restlessness, insomnia, emesis, diarrhea, craving, rejection of smoking and pupils were observed and/or questioned. Two of the 47 outpatients took heroin on the first days.(ABSTRACT TRUNCATED AT 250 WORDS)

In Egypt, 400 randomly selected pregnant women attending prenatal clinics affiliated with El-Shatby Maternity Hospital, Dar El-Welada Hospital, Gamal Abdel Nasser Hospital, Boharram Bay Maternal and Child Health Center, and Bacous Maternal and Child Health Center were interviewed to determine their knowledge of and practices related to drug intake during pregnancy. 47.7% had adequate knowledge (i.e., 75% correct answers) of drug use during pregnancy. Only 14% did not use any drugs during pregnancy. The remaining 86% used drugs without a prescription. The most common drugs used were vitamins and tonics (78.8%), antacids (66.5%), analgesics (41.8%), and antiemetics (35.5%). The leading reasons for drug use included general weakness (78.8%), heart burn and indigestion (66.5%), headaches (41.8%), vomiting (35.5%), and cough and insomnia (27.5%). Factors associated with poor knowledge of drug use during pregnancy were: younger than 30, illiteracy, being a housewife, primigravidity, and history of abortion (p 0.05 for all factors). These findings indicate a need to inform pregnant women about the dangers of drug use during pregnancy, especially during the first 12 weeks of pregnancy. Nurses should play a key role in communicating these risks.

The withdrawal of heterocyclic antidepressants and antipsychotic agents can produce nausea, emesis, anorexia, diarrhoea, rhinorrhoea, diaphoresis, myalgias, paraesthesias, anxiety, agitation, restlessness and insomnia. The withdrawal of monoamine oxidase (MAO) inhibitors may result in severe anxiety, agitation, pressured speech, sleeplessness or drowsiness, hallucinations, cognitive impairment, delirium, suicidality and delusions of persecution. The withdrawal of antipsychotic agents may give rise to symptoms preceding the onset of psychosis. These potential harbingers of relapse include anxiety, agitation, restlessness and insomnia. The withdrawal phenomena reviewed are usually prevented by gradually reducing the total daily dosage of the pertinent drug. Antimuscarinic agents often alleviate the distress produced by the withdrawal of tricyclic antidepressants and antipsychotic agents. MAO inhibitor withdrawal syndromes may constitute medical emergencies. The prevention of the evolution of a MAO inhibitor withdrawal-precipitated syndrome is a high priority.

The chemistry, pharmacology, pharmacokinetics, clinical use, adverse effects, drug interactions, and dosage of felbamate are discussed. Felbamate (2-phenyl-1,3-propanediol dicarbamate) is chemically unrelated to any of the other currently marketed antiepileptic drugs (AEDs). It appears that felbamate, like phenobarbital and valproic acid, decreases the frequency of seizures by decreasing seizure spread and increasing seizure threshold. Oral felbamate is at least 90% absorbed, and peak concentrations are reached in one to six hours. The half-life is a little less than one day. A therapeutic range of plasma concentrations has not been determined. Felbamate has been used effectively as monotherapy and adjunctive therapy in patients with partial seizures with or without secondary generalization and as adjunctive therapy in children with partial or generalized seizures associated with Lennox-Gastaut syndrome. Felbamate may also be safe and effective in patients with generalized, absence, atypical absence, juvenile myoclonic, infantile, and gelastic seizures. The most frequently reported adverse effects of felbamate include nausea, anorexia, vomiting, headache, fatigue, somnolence, insomnia, and increased serum aspartate aminotransferase levels. The frequency of adverse effects is greater in patients receiving other AEDs in addition to felbamate. Felbamate affects the pharmacokinetics of phenytoin, carbamazepine, valproic acid, and methsuximide; other AEDs also affect the pharmacokinetics of felbamate. The dosage of felbamate should begin at 400 mg orally three times daily and then increase by 600 mg/day every two weeks to up to 3600 mg/day. If the patient is receiving other AEDs concurrently, their dosage should be decreased as the dosage of felbamate is increased. If the goal is to switch to felbamate, the dosage should be increased weekly as the dosages of other AEDs are reduced. Felbamate offers a safe and effective alternative to other AEDs in the treatment of partial and secondarily generalized seizures; partial and generalized seizures associated with Lennox-Gastaut syndrome; and atypical absence seizures, gelastic seizures, and other difficult to control seizures.

In a prospective study, the prevalence of 15 physical symptoms and symptom groups was evaluated in 1635 cancer patients referred to a pain clinic. In addition to pain, patients suffered an average of 3.3 symptoms: insomnia (59%), anorexia (48%), constipation (33%), sweating (28%), nausea (27%), dyspnea (24%), dysphagia (20%), neuropsychiatric symptoms (20%), vomiting (20%), urinary symptoms (14%), dyspepsia (11%), paresis (10%), diarrhea (6%), pruritus (6%), and dermatological symptoms (3%). While symptom prevalence was influenced by tumor site, pain intensity, and opioid treatment, only a minor relationship was seen between symptoms and gender, age, or tumor stage. The data emphasize that it is not sufficient to simply address pain during the treatment of patients with cancer pain; a more global approach to symptom management is necessary.

Between 1983 and 1990 a total of 74 freestyle mountaineers and 88 mountaineers with skis attempted to climb Mount Agri (Ararat). From the freestyle group two mountaineers were affected by acclimatisation disorder at 3200 m and seven at 4200 m above sea level. Acute mountain sickness (AMS) affected four mountaineers at 4200 m, eight at 4700 m, two at 5000 m and two at 5165 m, while 49 reached the summit. Only one of the mountaineers with skis was affected by AMS (at 4200 m), while all the others reached the summit. The symptoms of acclimatisation disorder and AMS, according to their degree of frequency, were headache, weakness, dyspnoea and palpitation, anorexia, nausea, vomiting, giddiness, ataxia and insomnia. Pulse rates varied between 115 and 124/min, and breathing between 30 and 38/min.

Acute altitude illnesses include acute mountain sickness (AMS), a benign condition involving headache, nausea, vomiting, irritability, insomnia, dizziness, lethargy, and peripheral edema, and potentially lethal high-altitude cerebral edema and pulmonary edema (HAPE). Recent evidence is summarized that AMS is related to cerebral edema secondary at least in part to hypoxic cerebral vasodilation and elevated cerebral capillary hydrostatic pressure. This results in reduced brain compliance with compression of intracranial structures in the absence of altered global brain metabolism. It is postulated that these primary intracranial events elevate peripheral sympathetic activity that acts neurogenically in the lung possibly in concert with pulmonary capillary stress failure to cause HAPE and in the kidney to promote salt and water retention. The adrenergic responses are likely modulated by striking increases of aldosterone, vasopressin and atrial natriuretic peptide. The effects of exercise on altitude-induced illness and various therapeutic regimens (acetazolamide, CO2 breathing, dexamethasone, and alpha adrenergic inhibitors) are discussed in light of this hypothesis.
