A cross-sectional descriptive study of clinical features and course of illness in a South African population with bipolar disorder
There is generally a lack of studies examining prevalence and phenomenology of bipolar disorder in Africa. In literature, a unipolar manic course of illness in particular is reported to be rare. The purpose of this study was to investigate and describe the course of illness and clinical features in a cross-section of patients diagnosed with bipolar disorder attending public hospitals in Limpopo Province, South Africa and to determine the rate of a unipolar manic course in this sample of patients. This was a descriptive, cross-sectional study of patients presenting with a history of mania between October 2009 and April 2010, to three hospitals in Limpopo Province. A purposeful sample of 103 patients was recruited and interviewed using the Affective Disorders Evaluation. This study confirms that a unipolar manic course is indeed much more common than rates suggested in present day literature with57% of the study sample only ever experiencing manic episodes. The study also confirms the debilitating nature of bipolar disorder with more than two-thirds being unemployed in spite of a quarter of the study subjects having a tertiary education. The high rates of attempted suicide, history of violence and history of drug abuse all furthermore points to the devastating effects bipolar disorder has on individuals and their families. Treatment choice appeared to be a combination of a mood-stabilising agent in combination with an anti-psychotic. It was found that two-thirds of study subjects had consulted with faith- or traditional healers. Significant gender differences appeared in that females were more likely to suffer from comorbid anxiety disorders, have a history of sexual trauma, and be HIV positive whilst men were more likely to have a forensic- and substance-abuse history, experience hallucinations and receive clozapine. Patients presenting with a unipolar manic course of illness, as described in this thesis, may contribute to the search for an etiologically homogeneous sub-group which presents unique phenotype for genetic research and the search for genetic markers in mental illness. A unipolar manic course therefore needs to be considered as a specifier in diagnostic systems in order to heighten the awareness of such a course of illness in bipolar disorder, with a view to future research.Thesis (MD)--University of Pretoria, 2012.Psychiatryunrestricte

Efavirenz: A review of the epidemiology, severity and management of neuropsychiatric side-effects
South Africa has the highest proportion of HIV-positive people in the world. HIV cannot be cured; however, there are several major classes of drugs used in its management. Efavirenz is one such agent of the class non-nucleoside reverse transcriptase inhibitors which inhibits the replication of the virus. Efavirenz is associated with causing neuropsychiatric side-effects (NPSEs), with almost 50% of patients experiencing at least one NPSE while on treatment. The NPSEs tend to occur within the first few days of initiation of therapy and resolve spontaneously within the first 4 - 6 weeks, with the most commonly reported being dizziness, insomnia, headache, abnormal dreams and impaired concentration. The plasma level of efavirenz and genetic polymorphisms are thought to play a role in the development of such NPSEs. NPSEs need to be treated according to severity. If necessary, efavirenz may be replaced with nevirapine or lopinavir/ritonavir. It should be remembered that nevirapine may also produce some severe side-effects such as skin abnormalities and hepatotoxicity. The monitoring of patients receiving efavirenz therapy should be ongoing, with those with a history of mental illness requiring closer monitoring than others

Evaluating neuropsychiatric symptomology in HIV-positive patients on efavirenz in public-sector clinics and psychiatric hospitals
Background: South Africa has the highest number of people living with human immunodeficiency virus (HIV) infection in the world. In 2014, an estimated 10.2% of the population was HIV-positive which amounted to 5.51 million people. Efavirenz forms part of the triple therapy backbone used in South Africa and is part of the firstline treatment for HIV. Efavirenz has been strongly associated with causing neuropsychiatric side effects in at least 50.0% of patients to whom it is prescribed. These side effects cause hesitation amongst healthcare professionals to prescribe this agent to patients with active mental illnesses. Aim: The aim of the study was to evaluate the neuropsychiatric side effects of efavirenz in HIV-positive psychiatric and non-psychiatric patients and to determine whether this drug may be recommended for use in an HIV-positive psychiatric patient population. Method: The study was divided into two parts, namely a quantitative portion and a qualitative portion. The quantitative study was a prospective drug utilisation study, while the qualitative portion consisted of semi-structured interviews carried out with healthcare professionals working with people living with HIV/AIDS (PLWHA). The study included five municipal clinics in the Nelson Mandela Metropole as well as two public-sector psychiatric facilities in the Eastern Cape where medical records were reviewed to obtain the information required. Patients were followed in both instances for a period of 24 weeks with follow-up assessments carried out at two, four, 12 and 24 week intervals. In terms of the qualitative study, nurses at the clinics and doctors at the hospitals were contacted and appointments for interviews were made. The interviews were recorded using a voice recorder and were transcribed and analysed using theoretical framework analysis. Results: The review of 126 medical records at the clinics revealed that no patient had suffered from or complained of a neuropsychiatric side effect. This may indicate that patients were not suffering from clinically significant side effects, side effects were not being adequately recorded by healthcare staff, or the healthcare staff were not questioning patients regarding side effects. A total of 26 hospitalised patients were followed for 24 weeks in the psychiatric facilities. Almost half of the patients using efavirenz experienced an improvement in symptoms to the extent that they were iii discharged from the facility. The majority of patients (66.7%) not on an efavirenzcontaining regimen did not improve to the point of discharge. Healthcare staff were vague when providing a definition of neuropsychiatric side effects. There were conflicting ideas on whether or not efavirenz should be used in patients with an active psychiatric illness. Conclusions: Further studies need to be performed in public-sector institutions to obtain a clearer picture of the side effects experienced by patients using efavirenz. Healthcare staff need to be encouraged to keep complete records to allow for meaningful analysis. The further integration of mental health services into existing HIV programmes is essential for holistic treatment. Patients in psychiatric hospitals demonstrated that even patients with psychiatric disorders on efavirenz can experience positive outcomes and stabilisation of psychiatric symptoms, which may indicate that these may not have due to efavirenz use. Further elucidation concerning the use of efavirenz in patients with psychiatric disorders, a description of the neuropsychiatric side effects, as well as management strategies must be provided in subsequent HIV guidelines
Franz Liszt: (1811-1886): The Two Episodes from Lenau's Faust as a Unified Work
Franz Liszt composed his Two Episodes from Lenau's Faust between 1856 and 1861. The composer intended to portray two emotionally contrasting scenes from Lenau's Faust in a set for orchestra, the first being The Night Procession and the second The Dance in the Village Inn. Liszt created a duet version of the orchestral set, and also a solo piano version of The Dance in the Village Inn, known as the Mephisto Waltz No. 1. The set was not performed together due to the immense popularity of The Dance in the Village Inn but also due to an unfortunate publication history resulting in the pieces being published separately by Schuberth publishers, published years apart from each other. As a result The Night Procession is largely forgotten today and The Dance in the Village Inn is interpreted as a single work outside of its context in a set. In this dissertation the works are examined from within its context in a set. Background information includes information on Liszt's student Robert Freund (1852-1936), and a solo piano transcription of the orchestral alternative ending to The Dance in the Village Inn. A comparison between Liszt's orchestral, solo and duet versions of the Mephisto Waltz No. 1 and the Liszt-Busoni Mephisto Waltz No. 1 is also made
A review of trials investigating efavirenz-induced neuropsychiatric side effects and the implications
Background: Efavirenz is part of the first-line treatment for HIV patients including South Africa with approximately 50% experiencing neuropsychiatric side effects. Objective: Systematic review of papers reporting neuropsychiatric side effects with efavirenz published between January 2001 and December 2014 to provide guidance. Results: 13 articles were reviewed. Patient ages ranged between 37 to 41 years, with a high percentage males. Scales used to measure incidence and severity of side effects were varied; with disease severity or stage not reported. Patients with psychoses were excluded. Most commonly reported side effects were a reduction in sleep quality, depression, dizziness and anxiety. These were generally mild and not warranting discontinuation of efavirenz. Conclusion: Difficult to directly compare the studies. Standardised methods need to be introduced and all patient groups represented including the elderly, children, patients with active symptomatic illness and more women especially among the African population
