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

Neural and Psychosocial Mechanisms Underlying Alcohol Use and Pain Interactions: Overview of Current Evidence and Future Directions

Purpose of Review

A growing body of research indicates bidirectional associations between alcohol use and pain. In this review, we highlight common neural and psychosocial mechanisms underlying pain and alcohol use and identify current gaps in the literature regarding alcohol/pain interactions. We also suggest future directions for the field moving forward, including more nuanced conceptualization of alcohol's negative reinforcing effects in the context of pain, broader use of clinically-relevant experimental pain induction modalities, and characterization of age, biological sex, gender, race, and ethnicity as moderators of pain/alcohol interactions.

Recent Findings

Acute alcohol intake has analgesic and negative-reinforcing effects in the context of pain, and chronic heavy alcohol use appears to increase risk for development of chronic pain. At the same time, pain, both acute and chronic, acts as a proximal antecedent for alcohol use and is associated with relapse risk for individuals in recovery from alcohol use disorder.

Summary

Although the links between alcohol use and pain are increasingly appreciated, significant gaps in understanding remain and systematic study of alcohol/pain interactions at all levels, including basic, preclinical, translational, and interventional, is needed.

[Frequency and characterization of self-medication for dental manifestations in patients attending private clinics in Lima in 2021]

Introduction

The self-medication is the use of drugs without health professionals' prescription that many times, instead of helping, aggravate the patient's health. Dental pain is the main reason for performing this act in the area of odontology. It is important to know if patients self-medicate in order to develop strategies to reduce the misuse of drugs and avoid this practice.

Objective

Establish the frequency and characterization of self-medication in patients who visit to the three private dental clinics between the months of march to July in the year 2021.

Materials and methods

Cross-sectional observational study with a sample of 450 patients from three dental clinics in the city of Lima. The assessment tool was a 13-question quiz about the main characteristics of self-medication.

Results

The 85,8% of patients use drugs without medical prescription. 41.5% of the patients self-medicated did it with old prescriptions made by the dentist. The age group that more self-medicated was 26-35 years old with 35.5%. The most frequent type of disease was dental pain with 45.6%, The degree of instruction with the highest percentage was complete university superior with 32.9%.

Conclusions

The frequency of self-medication of the patients who visited the three dental centers is considerably high.

Paracetamol misusing to dental pain: a case-report and recommandations for treatment

Introduction: The paracetamol is the most widely used painkiller to dental pain. Patients self-medicating with paracetamol for dental pain had 12.8 more times lead to overdose than patients with other pains. The aim of this work was to propose a standardized management in case of paracetamol overdose from a clinical case report. Observation: A 56-year-old man was referred to the General Emergency Department because he had ingested 32 grams of paracetamol in less than 24 hours due to a dental pain. He was in a state of haemodynamic and hypothermic shock. He was placed on the liver transplant list due to fulminant hepatitis. The dental check-up found juxta-pulpal carious lesions on the four wisdom teeth which were removed before the transplantation. Conclusion: Paracetamol overdose is one of the leading causes of liver failure. The estimated toxic dose was 150 mg/kg/day or about 10 g/day. N-acetylcysteine treatment should be leaded early, between 8 and 10 hours after ingestion. The paracetamol-aminotransferase, as a risk prediction tool, reproductibles methods and biomarkers can identify overdoses and lead to a faster medical care. Information campaigns and warning articles on overdosing risk must be continued to strengthen the prevention message for the population.

Pain relief with combination acetaminophen/codeine or ibuprofen following third-molar extraction: A systematic review and meta-analysis

OBJECTIVE

The purpose of our study was to perform a systematic review and meta-analysis of randomized, blinded, placebo-controlled studies that, following third-molar extraction, utilized either a combination of acetaminophen (600 mg) with codeine (60 mg) or ibuprofen (400 mg) for pain management.

DESIGN

We searched PubMed, and the trial registry ClinicalTrials.gov databases with the keywords "molar or molars", "tooth or teeth", "extraction" and "pain". Selected studies were: (1) randomized, blinded, placebo controlled, (2) utilized either a single-dose combination acetaminophen (600 mg) with codeine (60 mg) (A/C) or ibuprofen, and (3) recorded standardized pain relief (PR) at 6 hours, or summed total pain relief over 6 hours (TOTPAR6). Of the 2,949 articles that were identified, 79 were retrieved for full-text analysis, and 20 of these studies met our inclusion criteria.

RESULTS

For A/C, the weighted, standardized mean difference (SMD) for TOTPAR6 was 0.796 (0.597-0.995, 95% confidence interval), P < 0.001, and for PR at 6 h, the SMD was 0.0186 (0.007 to 0.378; P = 0.059), whereas for ibuprofen the SMD for TOTPAR6 was 3.009 (1.283 to 4.735; P = 0.001), and for PR at 6 h, the SMD was 0.854 (95% CI, 0.712 to 0.996; P < 0.001). A SMD of 0.8 or larger is indicative of a large effect.

CONCLUSIONS

Our data indicate that single dose of ibuprofen (400 mg) is an effective pain reducer for post third molar extraction pain.

Sex moderates the effects of experimentally induced musculoskeletal pain on alcohol demand in healthy drinkers

BACKGROUND

Pain may serve as an antecedent for alcohol use, increasing risk for hazardous drinking and associated consequences. Delayed onset muscle soreness (DOMS) induction produces clinically relevant but time-limited musculoskeletal pain. This study was conducted to determine whether DOMS induction on the dominant elbow flexors influenced alcohol demand using the Alcohol Purchase Task (APT). We hypothesized DOMS would increase alcohol demand relative to a sham control. Based on existing studies of pain self-medication, we expected DOMS-related increases in alcohol demand would be greatest in men.

METHODS

Participants (N = 53; 57 % women) were randomly assigned to a DOMS (eccentric exercise) or sham condition (concentric exercise). Participants completed the APT pre-exercise and 48 -hs post-exercise. Repeated measures GLM was used to characterize group by sex by time interactions on APT indices, including intensity, breakpoint, essential value (EV), O_max, and P_max.

RESULTS

The DOMS procedure significantly increased pain ratings at the elbow flexors. Men had significantly higher demand intensity than women across groups and time points. Significant interactive effects were detected for breakpoint and EV. From pre- to post-test, breakpoint significantly increased in men in the DOMS group. However, breakpoint and EV significantly decreased in women in the DOMS group.

CONCLUSIONS

Increased alcohol demand in men in the DOMS group was consistent with epidemiological data suggesting men are at higher risk for self-medicating pain with alcohol than women. However, decreased demand in women was unexpected. Taken together, results indicate DOMS induction may be a useful means to characterize pain as an antecedent for alcohol use.

Sociodemographic Determinants and Common Reasons for Visiting the Emergency Dental Service in the City of Zagreb

Objective

The objective of the study was to determine the sociodemographic and clinical parameters of patients who visit the emergency dental service and their most common diagnoses.

Materials and Methods

The data were collected on the basis of a survey filled out by patients. A total of 1730 out of 6732 patients (26%) were surveyed using a questionnaire to analyze sociodemographic status, dental visits, the description and dynamics of the symptoms. After the data collection, methods of descriptive data presentation and of inferential statistics were made in SPSS.

Results

Survey results show that most subjects (60.4%) came during the weekends and holidays. The subjects, 73.1% of them, stated that they had already used this type of service, and 65.8% did not visit their dentist beforehand. The largest number of subjects (62.2%) reported that they needed emergency service within a week after their problems had begun. The most common diagnoses included face and jaw abscesses (27.3%). There is a statistically significant difference between the number of patients who went to the emergency dental service and completed the questionnaire over the course of several months contrary to patients who were there in May and June (59.7%) compared to July and August (40.3%).

Conclusions

Most subjects had clear indications for being referred to an emergency dental service. Most of the emergency conditions were mainly due to irregular visits to the dentist. Patient education and preventive programs would probably have reduced the number of visits.
