Lamotrigine compared with lithium in mania: a double-blind randomized controlled trial.

BACKGROUND: Preliminary data from case reports and small open trials suggest a role for lamotrigine in the treatment of bipolar disorder, although controlled data for the manic phase are lacking. METHOD: Thirty inpatients with a DSM-IV diagnosis of bipolar I disorder, currently manic, were randomly allocated to receive either lamotrigine (25 mg once daily for 1 week, 50 mg once daily for the second week, and 100 mg once daily for the last 2 weeks) or lithium (400 mg twice daily) in a 4-week randomized, double-blind, clinical trial. RESULTS: Both treatments improved symptoms of mania, as assessed by the Mania Rating Scale, Brief Psychiatric Rating Scale, Clinical Global Impression severity and improvement scales, and the Global Assessment of Functioning scale. There were no significant differences between groups at any time point, suggesting that the dose escalation required for lamotrigine did not adversely affect its onset of action. Secondary outcome measures, including the use of lorazepam as rescue medication, did not differ between the groups. No significant adverse events were noted in either group. CONCLUSION: In this pilot study, lamotrigine was as effective as lithium in the treatment of patients with bipolar disorder hospitalised for acute mania.

Olanzapine compared to lithium in mania: a double-blind randomized controlled trial.

Neuroleptics are of established efficacy in mania. Controlled data on the use of olanzapine in mania is however, absent. In this study, 30 patients meeting DSM-IV criteria for mania were randomly allocated to receive either olanzapine or lithium in a 4 week double-blind randomized controlled design. There were no significant outcome differences between the two groups on any of the primary outcome measures, the Brief Psychiatric Rating Scale (lithium 28.2; olanzapine 28.0; P = 0.44); Clinical Global Impression (CGI) improvement scale (lithium 2.75, olanzapine 2.36; P = 0.163) or the Mania Scale (lithium 13.2, olanzapine 10.2; P = 0.315). Olanzapine was however, significantly superior to lithium on the CGI-severity scale at week 4 (lithium 2.83, olanzapine 2.29; P = 0.025). Olanzapine did not differ from lithium in terms of treatment emergent extrapyramidal side-effects as measured by the Simpson-Angus Scale. Olanzapine appears to be at least as effective as lithium in the treatment of mania.

A comparison of olanzapine with haloperidol in cannabis-induced psychotic disorder: a double-blind randomized controlled trial.

Little controlled data exist on the treatment of substance induced psychotic disorders. In this study, 30 patients meeting DSM-IV criteria for cannabis induced psychotic disorder were randomly allocated to receive either olanzapine or haloperidol in a 4-week double-blind clinical trial. There were no significant outcome differences between the two groups on any of the primary outcome measures, the Brief Psychiatric Rating Scale (haloperidol 25.7; olanzapine 27.1; P = 0.70); Clinical Global Impression (CGI) severity scale (haloperidol 1.8, olanzapine 2.3; P = 0.21) or the CGI improvement scale (haloperidol 1.3, olanzapine 1.7; P = 0.16). The haloperidol group however, developed significantly more extrapyramidal side-effects as measured by the Simpson Angus Scale (haloperidol 11.4, olanzapine 2.5; P = 0.014). Significantly (P = 0.027) more biperidin was used for extrapyramidal side-effects in the haloperidol (7.143 mg) than in the olanzapine (0.357 mg) group. Olanzapine appears to be as effective as haloperidol in the treatment of cannabis induced psychotic disorder, but is associated with a lower rate of extrapyramidal side-effects.

Superiority of lithium over verapamil in mania: a randomized, controlled, single-blind trial.

BACKGROUND: Both case reports and small controlled studies suggest the efficacy of verapamil in the treatment of mania. METHOD: Forty patients with DSM-IV mania were studied in a 28-day randomized, controlled, single-blind trial of either lithium or verapamil. RESULTS: The patients receiving lithium showed a significant improvement on all rating scales (Brief Psychiatric Rating Scale [BPRS], Mania Rating Scale [MRS], Global Assessment of Functioning [GAF], and Clinical Global Impression [CGI]) compared with those receiving verapamil. The mean MRS score at Day 28 in the lithium group was significantly lower than that in the verapamil group (17.47 vs. 24.43, respectively; F = 6.17, df = 1, p = .018). A similar pattern was seen with the BPRS (12.68 vs. 20.57; F = 10.69, df = 1, p = .002), CGI (2.31 vs. 3.33; F = 6.05, df = 1, p = .019), and GAF (43.52 vs. 52.31; F = 4.36, df = 1, p = .044) (ANCOVA). CONCLUSION: This study suggests that lithium is superior to verapamil in the management of acute mania.

Analysis of failure following definitive radiotherapy for invasive transitional cell carcinoma of the bladder.

PURPOSE: To assess prognostic factors for bladder relapse and distant failure following definitive radiotherapy for invasive transitional cell carcinoma (TCC) of the bladder. METHODS AND MATERIALS: Retrospective review of patients treated in the period 1977 to 1990 by definitive radiotherapy. The factors studied included age, sex, T stage, histological grade, tumor multiplicity, ureteric obstruction, total radiation dose, and use of neoadjuvant chemotherapy. The endpoints studied were bladder relapse and distant failure. RESULTS: There were 342 patients with a mean follow-up time of 7.9 years. Bladder relapse was observed in 159 patients. The overall actuarial bladder relapse rate at 5 years was 55% (SE = 3%). Prognostic factors for a higher bladder relapse rate were: tumor multiplicity (p < 0.001), presence of ureteric obstruction (p = 0.001), and higher T stage (p = 0.044). Distant failure occurred in 39 patients. The overall actuarial distant failure rate at 5 years was 28% (SE = 3%). Prognostic factors for a higher distant failure rate were: ureteric obstruction (p = 0.003) and higher T stage (p = 0.030). CONCLUSION: In our study, patients with invasive bladder TCC fell into distinct prognostic groups determined by the three independent factors, ureteric obstruction, tumor multiplicity, and T stage. These factors provided estimated risks of bladder relapse by 5 years which ranged from 34% to 91%. Knowledge of these prognostic factors can help in the selection of patients more suited for bladder preservation by definitive radiotherapy.

Imipramine binding to blood platelets and aggressive behavior in offenders, schizophrenics and normal volunteers.

The relationships between [3H]imipramine binding to blood platelets and manifestation of aggressive behavior was studied in three different groups of subjects. Arrested offenders displayed high imipramine binding compared to controls, with violent offenders exceeding their nonviolent counterparts. Hostile schizophrenic patients showed imipramine binding higher than nonhostile matched patients. In normal volunteers, on the other hand, no correlation between imipramine binding and scores of aggression was found. The results support the notion about the involvement of a neuronal serotonergic system in the regulation of aggressive behavior. The contribution of this biological factor is detectable in pathological manifestation of aggression but not in normal behavior.

[Eye trauma in southern Africa].

The population of southern Africa living in South Africa, Swaziland, Lesotho and Mozambique is 50 million. Because of intertribal hostility, the particular family structure, and the widespread use of alcohol and cannabinoid drugs, violence is very common. Trauma results mainly from "cold" weapons, which are an essential part of the traditional accoutrements of the African male. 202 patients (31.86% of those who underwent eye surgery in 2 years) needed surgery for severe ocular trauma in Mbabane, Swaziland. In a similar period, 100 patients (19.49%) required similar surgery in Boksburg, South Africa.

Results of external beam radiotherapy in 448 patients with clinically localized adenocarcinoma of the prostate.

The results of external beam radiotherapy for clinically localized adenocarcinoma of the prostate in 448 patients treated in the period 1980-90 were reviewed. The average follow up was 4.9 years. The patients were aged 44-87 years (median 69 years) and all had histopathological evidence of adenocarcinoma by needle biopsy or transurethral resection of prostate. The histopathological grading was: 127 G1; 154 G2; 127 G4; 28 Gx. Clinical staging according to TNM (American Urological Association) was: 29 T0 (A2); 4 T1 (B1); 173 T2 (B2); 176 T3 (C1); 63 T4 (C2); 3 Tx. Routine surgical pelvic lymph node staging was not performed but patients had radiological (computerized tomography scan or lymphogram) nodal staging: 350 N0; 22 N1; 12 N2; 64 Nx. High energy linear accelerator external beam radiotherapy was given by multiple fields to total doses of 50-70 Gy (median 60 Gy). The majority of patients (307, 69%) was treated by a uniform policy under the care of one radiation oncologist (HM). The rates of local and distant failure at 5 years were 10% (s.e. = 2%) and 42% (s.e. = 3%), respectively. The late complication rate at 5 years was 25% (s.e. = 2%), comprising mild 16%, moderate 7% and severe 1.3%. The 5 year overall survival rate was 64% (s.e. = 2%) and the cancer-specific survival rate was 74% (s.e. = 3%). Both histological grade and clinical stage were strongly predictive of overall survival and distant failure. Only histological grade was predictive of local failure.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cobra bite: ophthalmic manifestations].

The venom of the cobra snake contains a mixture of several toxic enzymes and proteins. It has a direct action on the respiratory centers, as well as curariform interference at the neuromuscular junction, resulting in death from respiratory paralysis. It can injure the visual system by damaging the retinal cells, causing bilateral optic neuritis and cortical blindness. Due to a particular configuration of its venom ducts, the African cobra is capable of poisoning both by biting or by spitting its venom. We present an 18-year-old woman with severely impaired visual function which resulted from a cobra bite in childhood.

The management of invasive transitional cell carcinoma of the bladder. Results of definitive and preoperative radiation therapy in 390 patients treated at the Prince of Wales Hospital, Sydney, Australia.

The treatment results for invasive transitional cell carcinoma (TCC) of the bladder were assessed in a series of 390 patients referred to the Department of Radiation Oncology at the Prince of Wales Hospital, Sydney, Australia, during the period 1977 to 1988. These patients were managed by one of two strategies: cystectomy (87 patients) and radiation therapy (303 patients). Actuarial survival rates (death from any cause) were determined and comparisons were made using log-rank tests and Cox regression analyses. The mean follow-up time was 7.6 years. Independent prognostic factors for shorter survival were: the presence of a ureteric obstruction (P less than 0.001), increasing clinical stage (P less than 0.001), increasing patient age (P = 0.003), and earlier year of presentation (P = 0.008). Comparison of the two strategies indicated no significant difference in overall survival after adjusting for imbalances in prognostic factors (P = 0.007 unadjusted; P = 0.29 adjusted). The slightly longer survival of 46 patients from 1983 onward who received primary systemic chemotherapy (compared with 149 patients not given chemotherapy) was not statistically significant (P = 0.12 unadjusted; P = 0.56 adjusted for prognostic factors). The 5-year actuarial rates of severe complications were 8.0% after cystectomy and 5.3% after radiation therapy. In 303 patients treated by definitive radiation therapy, the 5-year actuarial rate of freedom from bladder failure for all clinical tumor stages was 44% (Tx, 67%; T1, 45%; T2, 56%; T3, 39%; and T4, 39%). These results suggest that definitive radiation therapy is a viable alternative to radical cystectomy for patients with invasive TCC of the bladder.

Training volunteers to work with the chronic mentally ill in the community.

The psychiatric literature gives evidence supporting the use of volunteers in caring for chronic psychiatric patients in the community. Thorough training of volunteers can be expected to enhance the quality of care they provide and help them to maintain interest in their role. The ten-week training program described in this paper was designed to increase volunteers' knowledge of mental illness, improve the quality of care they provided, and stimulate interest in the volunteer role. Pre- and posttraining scores on a questionnaire indicated that volunteers' knowledge had increased. The volunteers rated most aspects of the training very highly and felt that the orientation had helped them meet their goals. Several volunteers indicated increased tolerance for the mentally ill. Many questions remain unanswered. For example, in the long run, what difference does such training make for the patients with whom the volunteers work? Will reluctant professionals be more willing to refer patients to volunteer-staffed programs if those volunteers have had intensive training? Is the training cost-effective? We feel that the potential benefits of volunteers working with the chronic mentally ill in the community make this an important area for future research.

The role of C. albicans in denture stomatitis.

Denture stomatitis is an erythematous disorder of the denture-bearing tissues, especially the maxillary hard palate. Frequently it mimics many oral lesions. Early diagnosis of the lesion is essential to assure rational therapy. A diagnostic procedure based upon the enumeration of Candida albicans appeared to be feasible. A control group of twenty fully dentate subjects with no clinical evidence of stomatitis was sampled to establish normal concentrations of C. albicans in the oral flora. Samples were taken from a triangular area of the hard palate, serially diluted in broth, and all dilutions were incubated aerobically. In the control population, C. albicans never exceeded 100 organisms per square centimeter per subject sample. A population of edentulous patients with denture stomatitis, prior to any therapy, was similarly sampled. In many of these patients the concentration of C. albicans always exceeded 10,000 organisms per square centimeter per patient. The patients received denture replacements and antimycotic antibiotic therapy. Follow-up cultures were taken 4 to 6 weeks after completion of therapy. All patients were found to be free of denture stomatitis.

Risperidone compared with both lithium and haloperidol in mania: a double-blind randomized controlled trial.

Case reports and studies of other neuroleptics suggest the efficacy of risperidone in the treatment of mania. Forty-five inpatients with DSM-IV mania were studied in a 28-day randomized, controlled, double-blind trial of either 6 mg daily of risperidone, 10 mg daily of haloperidol, or 800 to 1200 mg daily of lithium. The patients in all three groups showed a similar improvement on the total score for all rating scales at day 28 (Brief Psychiatric rating scale; lithium 9.1, haloperidol 4.9, risperidone 6.5, F = 1.01, df = 2, p = 0.37; Mania rating scale; lithium 15.7, haloperidol 10.2, risperidone 12.4, F = 1.07, df = 2, p = 0.35 [analysis of variance]). The Global Assessment of Functioning and Clinical Global Impression data showed a similar pattern of improvement. This study suggests that risperidone is of equivalent efficacy to lithium and haloperidol in the management of acute mania. The extrapyramidal side effects of risperidone and haloperidol were not significantly different.
