Recent epidemics and pandemics have highlighted a number of ethical concerns about the response to the increasing threat of emerging infectious diseases. Some of these ethical concerns are very fundamental. They include why a pandemic was declared, how much clinical information can be collected for public health without threatening patient confidentiality and how to ensure fairness in the distribution of resources. We discuss these issues and suggest approaches to resolve these dilemmas as we anticipate the next pandemic.

BACKGROUNDThe use of Cognitive Behavioural Therapy (CBT) techniques to manage chronic pain is relatively new and understudied in Singapore. Using data collected from group CBT programmes carried out at the Singapore General Hospital (SGH), we seek to explore the efficacy of the programme on pain intensity, self-efficacy, attitudes towards pain, and emotional factors. We also examined the efficacy of the longer 6- to 9-day group programme versus an abridged 2-day version called the Pacing Programme covering only some aspects of the full group programme.

MATERIALS AND METHODSTwenty-nine adult patients underwent the intensive 6- to 9-day group programme while another 10 patients underwent the abridged 2-day group programme. The more extensive group programme encompassed teaching patients cognitive-behavioural methods of coping with pain, such as setting goals, pacing, cognitive restructuring by thinking in more positively, distraction, problem solving, sleep hygiene, communication skills, ability to cope with changes, and relaxation techniques. The abridged programme focused mainly on developing pacing skills. Patients were required to fill out questionnaires at the beginning of the programme, end of the programme, and at the 1-month and 6-month follow-ups to monitor progress.

RESULTSPreliminary results for the intensive 6- to 9-day group programme indicate decrease in pain and pain distress levels, improvements in management of pain, increased confidence to carry out activities despite pain, increased positive self-statements and decreased negative self-statements, decrease in fear of harm and pathophysiological beliefs, as well as decreases in the levels of depression, anxiety, and stress. The abridged 2-day programme yielded little change in pain and pain distress levels, but a slight increase in confidence to carry out activities despite pain.

CONCLUSIONThese preliminary results provide some evidence supporting the efficacy of CBT techniques in chronic pain management and contribute to the growing body of evidence for the effectiveness of psychological and behavioural techniques in the management of chronic pain.

INTRODUCTIONMultidrug-resistant (MDR) Gram-negative healthcare-associated infections are prevalent in Singaporean hospitals. An accurate assessment of the socioeconomic impact of these infections is necessary in order to facilitate appropriate resource allocation, and to judge the costeffectiveness of targeted interventions.

MATERIALS AND METHODSA retrospective cohort study involving inpatients with healthcare-associated Gram-negative bacteraemia at 2 large Singaporean hospitals was conducted to determine the hospitalisation costs attributed to multidrug resistance, and to elucidate factors affecting the financial impact of these infections. Data were obtained from hospital administrative, clinical and financial records, and analysed using a multivariate linear regression model.

RESULTSThere were 525 survivors of healthcare-associated Gram-negative bacteraemia in the study cohort, with 224 MDR cases. MDR bacteraemia, concomitant skin and soft tissue infection, higher APACHE II score, ICU stay, and appropriate definitive antibiotic therapy were independently associated with higher total hospitalisation costs, whereas higher Charlson comorbidity index and concomitant urinary tract infection were associated with lower costs. The excess hospitalisation costs attributed to MDR infection was $8638.58. In the study cohort, on average, 62.3% of the excess cost attributed to MDR infection was paid for by government subvention.

CONCLUSIONMultidrug resistance in healthcare-associated Gram-negative bacteraemia is associated with higher financial costs--a significant proportion of which are subsidised by public funding in the form of governmental subvention. More active interventions aimed at controlling antimicrobial resistance are warranted, and the results of our study also provide possible benchmarks against which the cost-effectiveness of such interventions can be assessed.

Objective: To evaluate the quality of Arnebiae Radix (AR) and Dictamni Cortex (DC) and study the efficacy of herbal extracts of these two herbs on the treatment of allergic contact dermatitis (ACD). Methods: Qualitative and quantitative analysis of effective components was performed using High Performance Thin Layer Chromatography (HPTLC), High Performance Liquid Chromatography (HPLC), and HPLC-Quadrupole Time of Flight-Mass Spectrometry (HPLC-QTOF-MS). In vitro allergic ACD 3D model was established by incubating 3D reconstructed human epidermis (RHE) with skin sensitizer, potassium dichromate. A total of 65 gene expression that were associated with ACD, which included 24 antioxidant responsive element (ARE) and 41 SENS-IS genes were quantified by qRT-PCR. More than or equal to 10 ARE genes and 18 SENN-IS genes were induced by 1.3-fold, demonstrating the successful establishment of in vitro ACD model. Oil extracts of AR and DC were applied on the in vitro ACD model to study the efficacy. Results: Batch 3 of AR and batch 2 of DC showed presence of all active ingredients with the highest concentrations. Active ingredients of the herbs were extracted using a special oil and formulated into herbal oil extracts. The herbal oil extracts were able to down regulate the induced genes in the in-vitro ACD skin model, bringing the tissue back to homeostatic status. Conclusion: The oil extracts showed the potent efficacy of using AR and DC in ACD treatment. The combination study will be done to optimize the formulation ratio which will be developed into a topical cream.
