Neurological complications were examined in a multicentre, randomized, parallel-group study of 545 patients undergoing primary liver transplantation to compare the efficacy and safety of FK 506- and cyclosporin A-based immunosuppressive regimens (CBIR). In an additional analysis, patients were divided into early and late randomized cohorts to detect the influence of protocol amendements that allowed for FK 506 dose reductions. Initial follow-up was for 6 months. Tremor, headache and insomnia were the most frequently reported adverse events involving the neurological system. Whereas these neurological symptoms were observed significantly more often in FK 506-treated patients (P < 0.05 vs. CsA for the overall population), this was no longer the case for the late FK 506 and CBIR cohorts. The risk of FK 506-treated patients developing tremor was related to the initial i.v. dose, the rate of administration of the i.v. dose and the daily dose (P < 0.01). Headache was significantly correlated with the FK 506 dose (P < 0.05), and insomnia was not related to any dosing variable. Major neurological symptoms, including psychosis, convulsion, coma, aphasia and intracranial haemorrhage, were reported with a low frequency (0.4-5.2%), and differences between both treatment groups were neither significant for the overall population nor for the early and late cohorts of FK 506 and CBIR. Data from the late cohorts showed no differences in the overall incidence of neurological adverse events between FK 506- and CBIR-treated patients.

The Ramadan month represents a valuable opportunity to test the hypothesis that the course of the illness of bipolar patients can be disrupted by the change in social rhythm which usually occurs during this month. The objectives of this study were to follow up the mood state and blood lithium level of fasting Muslim bipolar patients who had been on lithium therapy for at least 3 months, and were clinically stable before being included in the study. Twenty bipolar patients were enrolled during the month of Ramadan in 1997. Diagnosis of bipolar disorder was according to ICD-10 criteria. Patients were assessed during the week before Ramadan, the second and the fourth weeks of the fasting month and the first week after its end, with the Hamilton Depression and Bech-Rafaelsen scales. The plasma concentration of lithium was also assessed. The main finding of the study was that 45% of the patients relapsed, 70% during the second week and the remaining patients at the end of Ramadan. These relapses were not related to plasma concentration of lithium. Most of the relapses were manic (71.4 %). Patients who did not relapse had insomnia and anxiety during the second and third weeks of the study. Side-effects of lithium increased and were observed in 48% of the sample, mostly dryness of the mouth with thirst and tremor. The result of this pilot study indicates that the Ramadan month may disrupt the mood state of bipolar patients. More studies are needed to confirm this observation and to evaluate the validity of the Ramadan model to study the impact of social rhythms on bipolar patients.

This first clinical study of olanzapine in Japanese patients with schizophrenia was conducted to investigate the efficacy and safety of olanzapine. Eighty-one patients were included in the analysis set. Mean modal dose for those patients were 9.4 +/- 3.6 mg/day. For the primary efficacy measure (Final Global Improvement Rating score), 14.8% of patients had remarkable improvement, 59.3% of patients had moderate improvement or better, and 86.4% of patients had slight improvement or better. Results from the Brief Psychiatric Rating Scale showed improvement from baseline in all clusters including positive psychotic symptoms (thought disturbance) but also against negative symptoms (anergia). The most commonly reported treatment-emergent signs and symptoms with > or =10% incidence, were insomnia, weight increase, excitement, sleepiness, and anxiety. There was a low incidence of extrapyramidal treatment-emergent signs and symptoms, and events reported were tremor (6.2%), muscle rigidity (3.7%), and akathisia (2.5%). The most commonly reported treatment-emergent laboratory changes, with > or = 20% of incidence, were prolactin elevations (24.3%) followed by increases in triglycerides (20.4%). However, mean prolactin values tended to be normalized during the study. This study result suggests that olanzapine is an "atypical" antipsychotic.

An 87-year-old woman was referred for evaluation of nervousness, tremor, insomnia, and fatigue of 2 months' duration. Initial laboratory evaluation revealed a suppressed thyrotropin level and an elevated triiodothyronine level. A review of her medications revealed that she had started taking several dietary supplements at the recommendation of her chiropractor before the onset of symptoms. One of these was tiratricol (3,5,3'-triiodothyroacetic acid or Triac), a substance sold as a dietary supplement despite classification as a drug by the Food and Drug Administration. Tiratricol has weak thyromimetic effects, can inhibit pituitary thyrotropin secretion, and in higher doses can significantly stimulate metabolism. Such was the case with this patient who presented with signs, symptoms, and biochemical evidence of hyperthyroidism that promptly resolved after discontinuation of tiratricol therapy. To our knowledge, this is the first reported case of documented thyrotoxicosis secondary to tiratricol use. Because tiratricol is still available for sale on several Internet sites, this case emphasizes the importance of inquiring about the use of dietary supplements in all patients. The availability of such products on the Internet increases the already complex task of monitoring patients' use of dietary supplements.

(1) The choice of treatment for children with obsessive-compulsive disorder is difficult. Behaviour therapy and antidepressants have not been assessed adequately in this setting, and their efficacy seems limited. Clomipramine was the first antidepressant to show a degree of efficacy. (2) Sertraline is the first drug to be licensed in France for children aged from 6 to 17 years with obsessive-compulsive disorder. (3) According to our literature search, the evaluation file on sertraline in this indication mainly contains data from a double-blind placebo-controlled trial involving 187 children. After 3 months of treatment, sertraline was significantly more effective than placebo, although most children remained symptomatic. Direct comparison is lacking, but sertraline seems as effective as clomipramine. (4) However, 13% of children receiving sertraline left this trial because of adverse events (3% on placebo; p = 0.02). The short-term safety profile of sertraline in children is the same as in adults, i.e. mainly nausea, agitation, headache, insomnia and tremor. (5) We have no data on the effects of prolonged sertraline therapy in children, particularly on neuropsychological development. (6) The first-line treatment of obsessive-compulsive disorder is behaviour therapy. Sertraline, like clomipramine, is an option when behaviour therapy fails or is unfeasible. The choice between sertraline and clomipramine should be discussed case by case, according to their safety profiles; however, we have more experience with clomipramine, which should therefore be preferred over sertraline.

The objective of the study was to evaluate the adverse reactions of Loratadine plus Pseudoephedrine Sulfate Repetabs Tables (LTD+PSE Repetabs) (Loratadine 5 mg + Pseudoephedrine 120 mg) twice daily with that of loratadine (5 mg) twice daily and pseudoephedrine (60 mg) quarter daily in the treatment of patients with allergic rhinitis. The study was designed as an investigator-blind, parallel group study. In this study, 56 patients were equally separated into 2 groups and treated for 14 days with either LTD+PSE Repetabs or loratadine + pseudoephedrine tablet. Both groups were comparable in age, gender, weight; baseline systolic blood pressure, diastolic blood pressure and pulse rate. The change of systolic blood pressure, diastolic blood pressure, and pulse rate did not reach clinical significance throughout the study period. There was no significant difference in occurrences of insomnia, palpitation, mouth dryness and anxiety. However, the incidence of patients with tremor at day 14 in the loratadine + pseudoephedrine tablet group was significantly higher than the LTD+PSE Repetabs group (39% vs 10.7%, p-value = 0.03). Furthermore, one patient in the loratadine + pseudoephedrine tablet group had to discontinue medication at day 7 due to insomnia. In conclusion, LTD+PSE Repetabs is well tolerated and has fewer adverse effects when compared to the loratadine + pseudoephedrine tablet.

Calcineurin inhibition with tacrolimus has been used after renal transplantation (RTPL) as rescue therapy for insufficient immunological control or if cyclosporin A (CSA) toxicity occurred. Neurologic side-effects occur but are rare in children, usually presenting as tremor; however, serious complications, e.g. the posterior leukoencephalopathy syndrome are also documented. Twenty children (10 girls) were switched to tacrolimus: 11 (55%) for immunological reasons (n = 9: steroid-resistant rejection; n = 2: recurrent rejections) and nine for CSA side-effects. Tacrolimus was started at a median of 8 wk (range 10 d to 8.7 yr) after RTPL and was continued for a median of 2.5 yr (range 5 wk to 4.6 yr). Renal function significantly improved over a period of 12 months following conversion to tacrolimus (glomerular filtration rate 56 +/- 19 vs. 66 +/- 16 mL/min/1.73 m2; p < 0.03; n = 13). Fifteen of 20 (75%) patients tolerated tacrolimus well. The most frequent side-effects were neuropsychological and behavioral symptoms in three children, ranging from anorexia nervosa-like symptoms with weight loss, amenorrhea, depression and school problems to severe insomnia and to aggressive and anxious behavior in one child. Only the latter child was exposed to toxic tacrolimus blood levels. All side-effects were fully reversible after discontinuation of tacrolimus. In conclusion, tacrolimus had a beneficial effect on renal function and was well tolerated in the majority of pediatric patients. However, neuropsychologic and behavioral side-effects are important and maybe underrecognized in children.

Ninty-five inhabitants of the gold mining area of Mt. Diwata (on Mindanao, Philippines), who were diagnosed to be mercury (Hg) intoxicated, were orally treated with 2 x 200 mg of the chelating agent DMPS (Dimaval, Co. Heyl, Germany) for 14 days in the course of a UNIDO project focusing on mercury pollution abatement. Blood and urine samples before and after treatment, urine after the first application of DMPS and a hair sample were collected and analyzed for Hg. Before and after treatment extensive anamnestic data were collected, medical and neurological investigations and some neuro-psychological tests were performed. In spite of the short time of treatment most of the patients reported a marked improvement of the complaints which were stated by them before the therapy and which are characteristic for a chronic Hg intoxication, for example tremor, loss of memory, sleeplessness, metallic taste, etc. But even in some of the objective neurological parameters like hypo-mimia, Romberg test and tests for tremor/ataxia a statistical significant improvement could be found. Significant improvements could also be found in two neuro-psychological tests (pencil tapping and Frostig). In some cases an extreme high urinary Hg excretion was found under the chelating therapy with DMPS, and by this a distinct reduction of the Hg body burden. Nevertheless, in most cases Hg in blood and urine was not markedly decreased by the treatment. This shows that the duration of the treatment (14 days) was not sufficient for a permanent decrease in Hg. As DMPS excretes Hg mainly through the kidney, it can be concluded that in most cases even after 14 days of treatment there was an ongoing redistribution of Hg from other tissues to the kidney. In conclusion, this study proves that a chelating therapy with DMPS is highly effective even in the case of a mixed chronic and acute intoxication with an unknown combination of Hg vapor, inorganic Hg and organic Hg=methylmercury (MeHg), as characteristic for gold mining areas in the third world. Adverse side effects were rarely reported. Only in one case the medication had to be terminated after the first application due to an allergic skin reaction.

Parkinson's disease (PD) is primarily a disease of elderly individuals with a peak age at onset of 55 to 66 years. It is characterized by bradykinesia, rigidity, tremor, and postural instability; and affects approximately 1 million individuals in the US and is the second most common neurodegenerative disease next to Alzheimer's disease. The motor symptoms of PD are the focus of pharmacotherapy, yet the nonmotor symptoms (e.g., dementia, psychosis, anxiety, insomnia, autonomic dysfunction, and mood disturbances) can be the most disturbing, disabling, and misunderstood aspects of the disease. Depressive symptoms occur in approximately half of PD patients and are a significant cause of functional impairment for PD patients. There is accumulating evidence suggesting that depression in PD is secondary to the underlying neuroanatomical degeneration, rather than simply a reaction to the psychosocial stress and disability. The incidence of depression is correlated with changes in central serotonergic function and neurodegeneration of specific cortical and subcortical pathways. Understanding comorbid depression in PD may therefore add to the understanding of the neuroanatomical basis of melancholia.

The purpose of this analysis was to compare treatment-emergent adverse events (TEAE) related to use of levetiracetam (LEV) reported by young and elderly patients with anxiety and cognitive disorders, and young epilepsy patients. The LEV database includes reports of TEAE from trials of patients with diagnoses of a cognitive disorder (N=719), an anxiety disorder (N=1510), or localization-related epilepsy (N=1023) who participated in clinical trials lasting up to 16 weeks. Patients were grouped as young (<65 years) or elderly (> or = 65 years). The most common TEAE occurring most frequently in the LEV-treated groups were abdominal pain, asthenia, headache, anorexia, weight loss, dizziness, insomnia, somnolence, and tremor. The only significant differences in TEAE were seen between young and elderly groups with anxiety disorders (>3% higher for LEV than for placebo-treated patients) in headache (5.2% elderly, -0.9% young, P=0.041), and tremor (5.2 and -0.5%, respectively, P=0.022) and between young anxiety patients and young epilepsy patients for somnolence (-0.7 and 5.4%, respectively, P=0.036). For the other TEAEs there was no evidence for consistent differences between young and elderly patients and between patients with different CNS disorders. Overall, LEV was well tolerated by all patient groups. The favorable adverse event profile suggests that LEV might be suitable for use by elderly patients.
