Clinical and demographic profile of catatonic patients who received electroconvulsive therapy in a South African setting

Background: Catatonia is a psychomotor dysregulation syndrome seen in several illnesses. Uncertainties exist regarding its prevalence and causes. While some research shows a strong association with mood disorders, other data show catatonia to be strongly associated with schizophrenia. Data from low- and middle-income countries are required. Aim: To determine the clinical and demographic profile of patients with catatonia that received electroconvulsive therapy (ECT) between 01 January 2012 and 31 December 2014. Setting: The study was conducted at Elizabeth Donkin Psychiatric Hospital in Port Elizabeth, Eastern Cape. The hospital has mostly patients admitted under the Mental Health Care Act 17 of 2002 as Involuntary Mental Health Care Users. Method: A retrospective chart review was conducted. Using the hospital ECT database, all files of patients who received ECT for catatonia were identified. Demographics, psychiatric and medical diagnoses, signs of catatonia and other data were abstracted from these files. Results: Forty-two patients received ECT for catatonia, of whom 34 (80.95%) were diagnosed with a psychotic illness. Schizophrenia was the most common diagnosis (n = 19; 45.24%), followed by psychotic disorder owing to a general medical condition (n = 8; 19.05). Human immunodeficiency deficiency virus was the cause in 75.00% of the patients whose medical conditions caused catatonia. Seven (16.67%) patients had mood disorders, with bipolar I disorder accounting for 6 (14.29%) of these. Conclusion: Psychotic disorders were more frequent than mood disorders in the sample. Schizophrenia was the most common diagnosis, followed by psychotic disorder owing to a general medical condition

Aqueous stem bark extract of Stereospermum kunthianum (cham, Sandrine Petit) protects against generalized seizures in pentylenetetrazole and electro-convulsive models in Rodents

Abstract: Stereospermum kunthianum, Cham Sandrine Petit (Bignoniaceae) known in English as pink jacaranda is used in traditional medicine to treat an array of ailments including febrile convulsions in infants and young children by the rural dwellers in Nigeria. This study examined the anticonvulsant activity of its aqueous stem bark extract (100 ­ 400mg/kg) against maximal electroshock and pentylenetetrazole-induced seizures in rodents. Phenobarbitone and ethosuximide were used as reference anticonvulsant drugs for comparison. Stereospermum kunthianum extract (200 ­ 400mg/kg, i.p.) remarkably protected (76.9% and 84.6 % respectively) the rats against electroshock-induced seizures. However, the extract (200- 400mg/kg) when administered orally showed a comparatively less effect (33.3% and 55.6% respectively) to the intraperitoneally administered extract in the maximal electroshock test. The extract (100-400mg/kg, i.p.) significantly delayed (p<0.05) the onset of pentylenetetrazole-induced clonic seizures but only slightly prolonged the time of death of the mice. Although the findings in the present study do not provide conclusive evidence, it appears that the aqueous stem bark extract of Stereospermum kunthianum produces its antiseizure effect by enhancing GABAergic neurotransmission and/or action in the brain. The results indicate that the aqueous extract possesses anticonvulsant activity in rodents and therefore tend to suggest that the shrub may be used as a natural supplementary remedy in the management, control and/or treatment of childhood convulsions. It can be concluded that the aqueous stem bark extract possesses anticonvulsant activity and therefore lend pharmacological credence to the traditionally claimed use in the treatment of childhood convulsions
