Are food allergic consumers ready for informative precautionary allergen labelling?

Precautionary allergen labelling (PAL) has resulted in consumer confusion. Previous research has shown that interpretive labels (using graphics, symbols, or colours) are better understood than the traditional ...

Analgesia (mis)usage on a dental emergency service: a patient survey

Abstract

Objectives

Analgesics are one of the most frequently used medicines. Self-medication and misuse have been described in the literature. The purpose of this study was to document analgesic (mis)use in a population seeking emergency dental treatment.

Material and methods

Patients consulting a dental emergency service were randomly asked to complete a questionnaire on analgesic use, knowledge and information on the analgesics and on their pain history. A photobook was used as an aid to identify products used. Descriptive statistics were combined with chi-square and Mann-Whitney U testing.

Results

Ninety-eight patients were included. Acetaminophen (69.4%) and ibuprofen (65.3%) were the most frequently used products. Nearly half of the subjects (43.9%) combined at least two analgesics. Although 42.9% of subjects were aware of the maximum daily dose, 62.2% of the subjects exceeded this limit, specifically 76.6% of subjects using ibuprofen and 32.4% of subjects using acetaminophen overdosing. Females overdosed significantly more than males. Ingestion on medical advice did not affect the overdose rates significantly. No significant relation was found between the absence of knowledge on the maximum daily dose and actual overdosing. No higher pain reduction was found in patients overdosing analgesics. The average number of days patients experienced pain before consulting the emergency unit was 12. A significant relation was found between the lag time and overdosing.

Conclusions

A large portion of the patients overdosed analgesics. Even prior medical advice did not reduce significantly overdose rates.

Clinical relevance

Dentists treating emergency cases clearly need to be aware of the high risk and high rates of overdosing analgesics in their patients.

Effects of photobiomodulation therapy and topical non-steroidal anti-inflammatory drug on skeletal muscle injury induced by contusion in rats—part 1: morphological and functional aspects

Abstract

Musculoskeletal injuries are very frequent and are responsible for causing pain and impairment of muscle function, as well as significant functional limitations. In the acute phase, the most prescribed treatment is with non-steroidal anti-inflammatory drugs (NSAIDs), despite their questionable effectiveness. However, the use of photobiomodulation therapy (PBMT) in musculoskeletal disorders has been increasing in the last few years, and this therapy appears to be an interesting alternative to the traditional drugs. The objective of the present study was to evaluate and compare the effects of PBMT, with different application doses, and topical NSAIDs, under morphological and functional parameters, during an acute inflammatory process triggered by a controlled model of musculoskeletal injury induced via contusion in rats. Muscle injury was induced by means of a single trauma to the animals' anterior tibialis muscle. After 1 h, the rats were treated with PBMT (830 nm; continuous mode, with a power output of 100 mW; 3.57 W/cm²; 1 J–35.7 J/cm², 3 J–107.1 J/cm², and 9 J–321.4 J/cm²; 10, 30, and 90 s) or diclofenac sodium for topical use (1 g). Morphological analysis (histology) and functional analysis (muscle work) were performed, 6, 12, and 24 h after induction of the injury. PBMT, with all doses tested, improved morphological changes caused by trauma; however, the 9 J (321.4 J/cm²) dose was the most effective in organizing muscle fibers and cell nuclei. On the other hand, the use of diclofenac sodium produced only a slight improvement in morphological changes. Moreover, we observed a statistically significant increase of muscle work in the PBMT 3 J (107.1 J/cm²) group in relation to the injury group and the diclofenac group (p < 0.05). The results of the present study indicate that PBMT, with a dose of 3 J (107.1 J/cm²), is more effective than the other doses of PBMT tested and NSAIDs for topical use as a means to improve morphological and functional alterations due to muscle injury from contusion.

The Correlation of Allergic Rhinitis with ABO Phenotype

Abstract

The aim of study the correlation of ABO phenotypes in patients of allergic rhinitis and controls and to compare our study with the previous studies to analyse the association of above. 100 patients with symptoms of allergic rhinitis and 100 controls individual were selected from same geographical region and paired by gender and age were enrolled in the study. Detailed history, examination and relevant radiological and hematological investigations were done. ABO phenotypes were identified in red blood cells using hemagglutination technique. This clinic-based observational study was conducted among the patients presenting with signs and symptoms of allergic rhinitis. Maximum no. of cases were seen in ABO phenotype O (52%), followed by A, B and AB (33, 12 and 3% respectively) and it was found to be statistically significant (p = 0.001). Also more number of male patients were found in B and O blood group which was statistically significant (OR 5.33, p = 0.017 and OR 3.63, p = 0.006 respectively). Controls showed marginalized difference in distribution among the basis of different ABO phenotypes. The O blood group phenotype of ABO histo-blood group system is associated with AR. This study contributes to the better understanding of the pathophysiology and clinical variability of this disease and may help to improve strategies towards its prevention and diagnosis. Additionally, ABO histo-blood group phenotyping, an inexpensive and easy to perform assay could be used to identify individuals at risk of developing allergic rhinitis.

Effectiveness of tip rotation in fibreoptic bronchoscopy under different experimental conditions: an in vitro crossover study

Abstract

Background

Proper manipulation of fibreoptic bronchoscopes is essential for successful tracheal intubation or diagnostic bronchoscopy. Failure of proper navigation and rotation of the fibrescope may lead to difficulties in advancing the fibrescope and might also be responsible for (unnecessary) difficulties and delays in fibreoptic tracheal intubation, with subsequent hypoxaemia. The present study, therefore, aimed to assess the effectiveness of tip rotation in flexible bronchoscopes in different experimental conditions.

Methods

Five differently sized pairs of fibrescopes (outer diameters of 2.2, 2.4, 3.5, 4.2, and 5.2 mm) were inserted into paediatric airway manikins via an appropriately sized laryngeal mask and were turned clockwise or anticlockwise at the fibrescope body or cord to 45, 90, and 180°, with the cord held either straight or bent. The primary outcome measure was the ratio of rotation measured at the tip over the rotation performed with the fibrescope body or cord.

Results

Overall, the 'body' turn was significantly less effective when a bent cord was present (mean difference ranging from 29.8% (95% confidence interval 8.8–50.9) to 117.4% (93.6–141.2). This difference was diminished when the 'cord' turn was performed. Smaller fibrescopes, with outer diameters of 2.2 and 2.4 mm, were inferior with respect to the transmission of 'body' rotation to the tip.

Conclusions

'Cord' turning of the fibrescope appears to be more effective in rotating the tip than a turn of the fibrescope 'body' only. Straightening the fibrescope cord and combined 'body' and 'cord' turning are recommended.
