Worldwide, the treatment of tuberculosis is based on evidence-based guidelines developed by the World Health Organization (WHO) for national tuberculosis programs. However, the importance of health related quality of life, the adequate management of side effects associated with antituberculosis drugs and the elaboration of tuberculosis treatment outcome categories are a few issues that need to be addressed in forthcoming WHO guidelines for the treatment of tuberculosis.

BACKGROUND: Based on the `European Position Paper on Rhinosinusitis and Nasal polyps (EP3OS 2007)`, this study aimed to investigate general practitioners (GPs) and other specialists` understanding when managing patients with acute rhinosinusitis (ARS) in Asia.
METHODOLOGY: Among a total of 2662 questionnaires completed, 2524 (94.8%) were valid for analysis. There were 1308 GPs (51.8%), 989 otolaryngologists (39.2%) and 227 paediatricians (9%) from Mainland China, Hong Kong, Indonesia, India, Malaysia, Pakistan, Philippines, Singapore, Thailand and Taiwan.
RESULTS: ARS is affecting an estimated 6 - 10% of patients seen in a daily out-patient practice. The EP3OS criteria are well supported by Asian physicians (94.1%). Most physicians (62.7%) agreed that radiological investigation is not needed to diagnose ARS. However, even for mild ARS (common cold), medical treatments were still recommended by 87% of GPs, 83.9% of otolaryngologists, and 70% of paediatricians. The top three first-line treatments prescribed were antihistamines (39.2%), nasal decongestants (33.6%), and antibiotics (29.5%). Antibiotics usage increased as the first line treatment of moderate (45.9%) and severe (60.3%) ARS.
CONCLUSION: ARS is commonly managed by GPs, otolaryngologists, and paediatricians in Asia. However, understanding of the management of ARS needs further improvement to minimize unnecessary use of radiological investigations, overuse of antibiotics, and under use of nasal corticosteroids.

Background Antihistamines are widely prescribed to children but should be used with caution in young children. Objective To determine the paediatric prescribing pattern of antihistamines with a focus on the off-label prescribing and factors that influence such prescribing. Setting Paediatric wards of a tertiary care hospital setting in Malaysia. Methods The pharmacy-based computer system and medical records were used to collect the required data. Labelling status of each antihistamine was determined based on the information provided in the product leaflets. Main outcome measure Antihistamines prescribed off-label and factors associated with such prescribing. Results Of the 176 hospitalised children aged <18 years prescribed with an antihistamine in the year 2012, 60.8 % received it in an off-label manner. Of 292 antihistamine prescription items, 55.5 % were prescribed off-label. Loratadine (35.3 %) was the most frequently prescribed antihistamine and chlorpheniramine maleate (34.0 %) was the most common antihistamine prescribed off-label. The main reason for the off-label prescribing of antihistamines was prescribing at higher than the recommended dose (30.2 %). Binary logistic regression showed that children aged <2 years (OR 12.65; 95 % CI 2.87-55.67) and the number of medications received (OR 1.14; 95 % CI 1.00-1.29) were significant predictors for the off-label prescribing of antihistamines. Conclusion Prescribing antihistamines for children in an off-label manner was prevalent at the studied locations and warrants further investigation on the consequences of such prescribing.
Bixa orellana L. has been traditionally used in Central and South America to treat a number of ailments, including internal inflammation, and in other tropical countries like Malaysia as treatment for gastric ulcers and stomach discomfort. The current study aimed to determine the major chemical constituents of the aqueous extract of B. orellana (AEBO) and to evaluate the antihistamine activity of AEBO during acute inflammation induced in rats.
