Diagnosis and Management of Headaches in the Emergency Department (ED) in Adults and Children.

BACKGROUND: Headache accounts for a significant number of cases presenting to the Emergency Department (ED) and has a high societal cost, contributed by recurrent ED and clinic visits, and unnecessary diagnostic tests. OBJECTIVE: This review article covers the important clinical tools needed to evaluate headaches in both adults and children in the ED. METHODS: Medline/PubMed was searched using the keywords "Emergency department", "headache", "adult", "pediatric", "clinical assessment", "diagnosis" and "treatment", in the title or abstract. The search covers the period from 1 January 1990 to 31 December 2019. RESULTS: The articles selected were based on their relevancy to the objective of this review article. Additional relevant publications were identified from article references lists. CONCLUSION: The emergency physician plays a key role in differentiating between primary and secondary headaches. Within the limited ED resources, appropriate diagnostic testing should be used to identify the life-threatening headaches. This will ensure patients are given the appropriate evidence-based pharmacological therapy and holistic management.

A qualitative study on pharmacists' perception on integrating pharmacists into private general practitioner's clinics in Malaysia.

BACKGROUND: Private general practitioners in Malaysia largely operates as solo practices - prescribing and supplying medications to patients directly from their clinics, thus posing risk of medication-related problems to consumers. A pharmacy practice reform that integrates pharmacists into primary healthcare clinics can be a potential initiative to promote quality use of medication. This model of care is a novel approach in Malaysia and research in the local context is required, especially from the perspectives of pharmacists. OBJECTIVE: To explore pharmacists' views in integrating pharmacists into private GP clinics in Malaysia. METHODS: A combination of purposive and snowballing sampling was used to recruit community and hospital pharmacists from urban areas in Malaysia to participate either in focus groups or semi-structured interviews. A total of 2 focus groups and 4 semi-structured interviews were conducted. Sessions were audio recorded, transcribed verbatim and thematically analysed using NVivo 10. RESULTS: Four major themes were identified: (1) Limited potential to expand pharmacists' roles, (2) Concerns about non-pharmacists dispensing medicines in private GP clinics, (3) Lack of trust from consumers and private GPs, (4) Cost implications. Participants felt that there was a limited role for pharmacists in private GP clinics. This was because the medication supply role is currently undertaken in private GP clinics without the need of pharmacists. The perceived lack of trust from consumers and private GPs towards pharmacists arises from the belief that healthcare is the GPs' responsibility. This suggests that there is a need for increased public and GP awareness towards the capabilities of pharmacists' in medication management. Participants were concerned about an increase in cost to private GP visits if pharmacists were to be integrated. Nevertheless, some participants perceived the integration as a means to reduce medical costs through improved quality use of medicines. CONCLUSION: Findings from the study provided a better understanding to help ascertain pharmacists' views on their readiness and acceptance in a potential new model of practice.

Autonomic and electrocardiographic findings in Parkinson's disease.

Parkinson disease (PD) is a progressive neurodegenerative disorder characterized by motor and non-motor symptoms and signs. Many reports suggest that diminished heart rate variability occurs early, even prior to the cardinal signs of PD. In a longitudinal study of PD, we evaluated whether heart rate variability (HRV) obtained using a 10-second ECG tracing, and the electrocardiographic QT-interval would be associated with PD severity and progression. Subjects were derived from a longitudinal study of 1741 individuals with early, stable PD. The severity of PD was measured using the global statistical test (GST). In a subset, the heart rate corrected QT-interval (QTcB) was calculated for each electrocardiogram (ECG). The HRV was measured for each ECG and then transformed to fit a normal distribution. The baseline analysis included 653 subjects, with 256 completing the 5-year follow up study. There was an association (P<0.05) between QTcB and PD severity in individuals that were taking QT-interval affecting drugs. A longer QT-interval at baseline was associated with more advanced PD at 5years (P<0.05), and greater disease progression over 5years (P<0.05). There was an association between diminished HRV and an orthostatic decrease in standing blood pressure at baseline in individuals with PD (P<0.05). HRV was not associated with PD severity or progression. In conclusion, we were able to detect measurable associations between the QTcB interval and PD severity, PD severity 5years later, and the change in disease over time. However, routine ECG tracings appear inadequate for the evaluation of autonomic function in PD.

Perceived sources of stress among Malaysian dental students.

OBJECTIVE: The study objectives were to identify the stress levels and to explore the impact of students' year of study and gender on the perceived sources of stress among Malaysian dental students. METHODS: This was a cross-sectional study involving dental students from year one to year five from private and public universities in Malaysia. The study was formally approved by the Research and Ethics Committee, International Medical University Malaysia. Dental Environment Stress (DES) questionnaire was used for data collection and the gathered data were analyzed using SPSS® version 18. The Kruskal-Wallis and the Mann-Whitney U tests were used to compare stress items across various academic years and universities. RESULTS: A total of five hundred and twenty nine (529) students participated in this study. Fear of failing the course at the end of year exams (mean stress level=5.57); concerns regarding completion of clinical work (mean=5.30); and examination results and grades (mean=5.27) were found as top stressors among dental students. Female students had higher stress scores than males with respect to personal issues, academic performance, educational environment and learning of clinical skills. Students from public universities had higher stress scores than their counterparts from private universities. CONCLUSIONS: The Malaysian dental students reported higher levels of stress. Present study identified stressors affecting dental students' academic life, and highlights the importance of stress management programs and other measures to minimize the impact of stress on both academic and personal lives of the students.
