Lymphatic filariases and soil-transmitted helminthiases in Sri Lanka: the challenge of eliminating residual pockets of transmission.

Sri Lanka has successfully met the challenge of controlling both lymphatic filariasis (LF) and soil-transmitted helminthiases (STH) as public health problems. The primary public health strategy for combatting both conditions has been preventive chemotherapy. The national programme for the elimination of LF implemented five annual rounds of mass chemotherapy in the endemic districts from 2002 to 2006 using a combination of diethylcarbamazine and albendazole. The overall microfilaria rate declined from 0.21% in 2001 before the mass chemotherapy, to 0.06% in 2016, at declaration of elimination of LF as a public health problem by the World Health Organization. Currently Sri Lanka is in the phase of post-validation surveillance. Achieving control of STH has been more difficult. Mass deworming programmes have been implemented for nearly a century, and national-level surveys reported prevalence rates declining from 6.9% in 2003 to 1% in 2017. However, neither of these infections has been completely eliminated. A situation analysis indicates continued transmission of both among high-risk communities. This paper explores the reasons for persistence of transmission of both LF and STH in residual pockets and the measures that are required to achieve long-term control, or perhaps even interrupt transmission in Sri Lanka.

Problem behaviours and psychotropic medication use in intellectual disability: a multinational cross-sectional survey.

BACKGROUND: Problem behaviours (PBs) are a common cause for clinician contact in people with disorders of intellectual development and may be a common cause for the prescription of psychotropic medication. We aimed to use a large, multinational sample to define the prevalence of PBs, the associations with psychotropic medication use, and to assess for any potential 'diagnostic overshadowing' by the label of PBs in a population of people with disorders of intellectual development. METHOD: A multinational, multi-setting, cross-sectional service evaluation and baseline audit was completed. Data were collected from UK hospitals, UK community settings, Sri Lanka and Hong Kong. A semi-structured questionnaire was completed by treating clinicians, capturing demographic details, prevalence rates of intellectual disability and psychotropic medication use, alongside psychiatric co-morbidity. RESULTS: A sample size of 358 was obtained, with 65% of included participants treated in an inpatient setting. Psychotropic use was prevalent (90%) in our sample, particularly antipsychotics (74%). The prevalence of PB was high (83%). There was no statistically significant association between psychotropic prescription and recorded psychiatric co-morbidity, suggesting prevalent 'off-label' use for PBs, or poor recording of psychiatric co-morbidity. There was some evidence of possible diagnostic overshadowing due to the PB classification. A higher dose of psychotropic medication was associated with aggression toward others (P = 0.03). CONCLUSIONS: We found evidence of prevalent potential 'off-label' use for psychotropic medication, which may be due to PBs. We also found evidence of potential diagnostic-overshadowing, where symptoms of psychiatric co-morbidity may have been attributed to PBs. Our findings provide renewed importance, across borders and health systems, for clinicians to consider a holistic approach to treating PBs, and attempting to best understand the precipitants and predisposing factors before psychotropic prescribing.

Personality disorders in offenders with intellectual disability: a comparison of clinical, forensic and outcome variables and implications for service provision.

AIM: To establish any differences between patients with and without a diagnosis of personality disorders, being treated in a secure inpatient service for offenders with intellectual disability (ID) in the UK. METHOD: A cohort study involving a selected population of people with ID and offending behaviours. Results The study included a total of 138 patients, treated over a 6 year period - 77 with a dissocial or emotionally unstable personality disorder and 61 without. Women were more likely to be in the personality disorder group. Both groups had high prevalence of abuse with no significant differences. Depressive disorders and substance abuse were more common in the personality disorder group, while epilepsy and autistic spectrum disorders were more common in the non-personality disorder group. Rather than differences, what was more striking was the rate and range of these comorbidities across both groups. Although past histories of violence and institutional aggression were no different, compulsory detention under criminal sections and restriction orders were more common in the personality disorder group. There were no differences in treatment outcomes. CONCLUSIONS: Although about half of patients detained in secure units for offenders with ID have a personality disorder, there were more similarities than differences between this group and the rest. While good treatment outcomes supported the case for specialised secure treatment units for people with ID, the case for establishing a more specialised ID-personality disorder unit was less convincing. There is also a need to explore whether there are alternative diagnostic models that can delineate better the group with personality difficulties in this population.

Maximizing the contribution doctors make to NHS management.

Management is an increasingly important issue for many doctors. If doctors wish to influence resource allocation, they must involve themselves in health service management. This article describes the results of an enquiry action learning project involving six doctors. As part of the project, clinical directors and their business managers were interviewed. In addition, the Police Force and BAA (formerly the British Airport Authority) were visited and their management structure, out-of-hours activities and planning for emergencies assessed. This article examines the reasons why many doctors do not involve themselves in management, such as increased time commitment and negative peer pressure, and suggests some solutions to these problems, including the need for a wider understanding of the role of clinical directors. It also considers how some organizations are already starting to address these issues, and how both doctors and hospitals can benefit from greater involvement of doctors in health service management.
