RESUMO

Psychiatric disorders are important predictors of deliberate self-harm. The present study was carried out to determine the associations between DSM-IV TR Axis- I & II disorders and deliberate self-poisoning (DSP) in a rural agricultural district in Sri Lanka. Patients residing in the district who presented with DSP were randomly selected for the study. Both the cases and age, sex, and, residential area, matched controls were assessed for DSM-IV TR Axis- I & II disorders based on the Structured Clinical Interview for DSM-IV-TR Axis I and II Disorders (SCID I & II) conducted by a specialist psychiatrist. Cases consisted of 208 (47.4%) males and 231 (52.6%) females. More than one third (37%) of males and more than half (53.7%) of females were aged below 20 years. DSM-IV TR axis-I and/or II psychiatric diagnoses were diagnosed in 89 (20.3%) of cases and 14 (3.2%) controls. Cases with a DSM-IV TR axis-I diagnosis were older than the cases without psychiatric diagnosis (32 and 19 years), p<0.0001. Having a depressive episode was associated with a 19 times higher risk for DSP. Being a male aged > = 30 years and having an alcohol use disorder carried a 21 times excess risk for DSP. A fivefold excess risk for DSP was found among 10-19 year old females with borderline personality traits. Depressive disorder and alcohol-related disorders were significantly associated with the older participants who presented with DSP. The overall prevalence of psychiatric disorders associated with DSP in rural Sri Lanka was significantly lower compared to the rates reported in the West and other countries in the region. Therefore, health and research priorities to reduce self-harm in Sri Lanka should focus both on psychiatric and non-psychiatric factors associated with DSP.

RESUMO

BACKGROUND: Non-invasive brain stimulation is being increasingly used to interrogate neurophysiology and modulate brain function. Despite the high scientific and therapeutic potential of non-invasive brain stimulation, experience in the developing brain has been limited. OBJECTIVE: To determine the safety and tolerability of non-invasive neurostimulation in children across diverse modalities of stimulation and pediatric populations. METHODS: A non-invasive brain stimulation program was established in 2008 at our pediatric, academic institution. Multi-disciplinary neurophysiological studies included single- and paired-pulse Transcranial Magnetic Stimulation (TMS) methods. Motor mapping employed robotic TMS. Interventional trials included repetitive TMS (rTMS) and transcranial direct current stimulation (tDCS). Standardized safety and tolerability measures were completed prospectively by all participants. RESULTS: Over 10 years, 384 children underwent brain stimulation (median 13 years, range 0.8-18.0). Populations included typical development (n = 118), perinatal stroke/cerebral palsy (n = 101), mild traumatic brain injury (n = 121) neuropsychiatric disorders (n = 37), and other (n = 7). No serious adverse events occurred. Drop-outs were rare (<1%). No seizures were reported despite >100 participants having brain injuries and/or epilepsy. Tolerability between single and paired-pulse TMS (542340 stimulations) and rTMS (3.0 million stimulations) was comparable and favourable. TMS-related headache was more common in perinatal stroke (40%) than healthy participants (13%) but was mild and self-limiting. Tolerability improved over time with side-effect frequency decreasing by >50%. Robotic TMS motor mapping was well-tolerated though neck pain was more common than with manual TMS (33% vs 3%). Across 612 tDCS sessions including 92 children, tolerability was favourable with mild itching/tingling reported in 37%. CONCLUSIONS: Standard non-invasive brain stimulation paradigms are safe and well-tolerated in children and should be considered minimal risk. Advancement of applications in the developing brain are warranted. A new and improved pediatric NIBS safety and tolerability form is included.

RESUMO

INTRODUCTION: Neurovascular lesions are rare and understudied in the pediatric population. Their initial presentation can range from seizures to focal neurologic deficits, as well as headaches. The goal of this study was to examine the clinical presentation and natural history of neurovascular lesions in children with epilepsy. METHODS: We reviewed all pediatric epilepsy patients with neurovascular lesions diagnosed between 2006 and 2018 at the University of Alberta and the Stollery Children's Hospital, Edmonton, Canada. Initial clinical presentation and brain imaging, as well as long-term epilepsy and postsurgical outcome, were assessed. RESULTS: Of the 14 patients, 10 patients had an initial presentation of focal seizures with impaired awareness, whereas 2 patients presented with headache, 1 presented with visual field defects as well as chronic headaches, and 1 with decreased level of consciousness. Seven patients had cavernous angiomas, 6 had arteriovenous malformation, and 1 patient had an arteriovenous fistula. Notably, all patients with cavernous angiomas and 4 of 6 patients with arteriovenous malformations presented with seizures. Among 9 of the 14 who underwent neurovascular corrective surgery, all 9 patients required long-term antiepileptic treatment of at least 1 antiepileptic drug for seizure control after the operation. CONCLUSION: In this novel case series, we describe focal seizures as the initial presentation of pediatric neurovascular lesions. This clinical presentation appears to be independent of the type of neurovascular lesion. Furthermore, unlike our pediatric surgical patients with epilepsy due to other causes, seizure freedom following neurovascular surgery is limited, and patients require long-term antiepileptic treatment.

RESUMO

INTRODUCTION: Repetition of deliberate self-harm is an important predictor of subsequent suicide. Repetition rates in Asian countries appear to be significantly lower than in western high-income countries. Methodological differences in studies, and the impact of access to means of self-harm with comparatively higher lethality have been suggested as reasons for these reported differences. This prospective study determines the rates and demographic patterns of deliberate self-poisoning (DSP), suicide and repeated deliberate self-harm resulting non-fatal and fatal outcomes in rural Sri Lanka. METHODS: Details of DSP admission in all hospitals (n = 46) and suicides reported to all police stations (n = 28) in a rural district were collected for the years 2011, 2012 and 2013. Demographic details of the cohort of patients admitted to all hospitals in 2011 due to deliberate self-poisoning (N = 4022), were screened to link with patient records and police reports of the successive two years with high sensitivity using a computer program. Then high specificity manual matching of all screened links was performed to identify repetition within 2 years of initial presentation. Life time repetition was assessed in a randomly selected subset of DSP patients (n = 433). RESULTS: There were 15,639 DSP admissions, aged more than 9 years, and 1078 suicides during the study period. The incidence of deliberate self-poisoning and suicide in the population within the study area were 248.3/100,000 and 20.7/100,000 respectively, in 2012. Repetition rates at four weeks, one-year and two-years were 1.9% (95% CI 1.5-2.3%), 5.7% (95% CI 5.0-6.4) and 7.9% (95% CI 7.1-8.8) respectively. The median interval between two attempts were 92 (IQR 10-238) and 191 (IQR 29-419.5) days for the one and two-year repetition groups. The majority of patients used the same poison in the repeat attempt. The age and duration of hospital stay of individuals with repetitive events were not significantly different from those who had no repetitive events. The rate of suicide at two years following DSP was 0.7% (95% CI 0.4-0.9%). The reported life time history of deliberate self-harm attempts was 9.5% (95% CI 6.7-12.2%). CONCLUSIONS: The comparatively low rates of repetition in rural Sri Lanka was not explained by higher rates of suicide, access to more lethal means or differences in study methodology.

RESUMO

Introduction: Attempted or non-fatal self-poisoning is an important public health problem in Sri Lanka. Current evidence from Sri Lanka suggests that this phenomenon is more common among young people, and females, and is associated with a recent interpersonal conflict. International studies indicate that recent non-fatal selfharm is associated with an increased risk of repetition and completed suicide. Prospective follow-up data regarding rates of repetition of self-harm in Sri Lanka is limited. Objectives: The aim of this study was to describe the rate of repetition, and rate of suicidal ideation, at one-year follow up among those who have survived an act of selfpoisoning. Methods: Participants who presented to the toxicology unit, Teaching Hospital Peradeniya over a 14-month period, for medical management of non-fatal self-poisoning, were contacted by telephone one-year following the initial presentation. Results: A total of 949 persons were included in the study, of which 35.3% (n=335) were contactable at one-year follow-up. The rate of repetition of self-harm after one year was 2.5% and 2.7% of participants had suicidal ideation at one-year follow-up. Conclusions: The rate of repetition of self-harm in Sri Lanka is lower than the rate reported in the West (15%).

RESUMO

BACKGROUND: Cultural factors may influence the manner in which a given population interprets and conceptualizes their experience of depression. The aim of this study is to validate the Peradeniya Depression Scale (PDS), a locally created, culturally relevant tool for detection of depression in Sri Lanka. METHOD: Fifty currently depressed patients (diagnosed via the Structured Clinical Interview for DSM Disorders) and 50 (non-depressed) controls were administered the PDS. RESULTS: At a score of 10/25 the PDS showed a sensitivity 88.5% and specificity of 85.0% with regards to the detection of depression. Culturally appropriate statements, which referred to international criteria of depression and somatic symptoms, showed significantly higher odds of being positive in depressed patients compared to controls. LIMITATIONS: The PDS was validated among an outpatient population presenting to a psychiatry clinic in a government hospital in Peradeniya, Sri Lanka. While this is fairly representative of patients presenting to government hospital clinics in this country, further multi-centre studies in different areas of the country maybe useful. CONCLUSION: The PDS is the first screening tool for depression developed and validated in Sri Lanka, written in Sinhalese, taking into account cultural expressions and idioms of the illness. It shows satisfactory sensitivity and specificity as a screening tool for depression. The findings also suggest that it maybe worthwhile for Asian countries to consider adopting scales which are based on internationally accepted diagnostic criteria for depression, but which incorporate expressions that are more appropriate to their own culture and language.
