A cross sectional study of sex differences in self-medication practices among university students in Slovenia

Self-medication patterns in adults depend on sex. Self-medication among students is very common, but little is known about the influence of sex. The aim of the study was to determine the incidence of self-medication college students and to determine the effect of sex on self-medication patterns. A web based incidence study conducted on a sample of Slovenian university students. The main outcome measures were percentages of male and female students reporting the use of self-medication in the past year. A majority of students (92.3%) reported the use of some sort of self-medication in the past year. Most female students (94.1%) and most male students (90.9%) reported the use of self-medication in the past year. The difference was not statistically significant. More female students than male ones (p < 0.05) acquired the drugs for self-medication in pharmacies, used OTC drugs, herbal teas, herbs, vitamins and minerals, remedies for muscle mass gain, antibiotics, benzodiazepines, antacids, acetylsalicylic acid, topical corticosteroids, and nasal decongestives only with the advice of physicians or pharmacists, and thought that increasing drug dosage can be dangerous, that in case of side effects physicians' help must be sought, that no drug can be used during pregnancy, and that self-treatment can mask the symptoms and signs of diseases so the physicians can overlook them easily. Sex appears to be important factor in self-medication patterns even in young adults, such as students. The physicians should actively seek the presence of self-medication in this population. Inappropriate or unsafe use should be properly addressed and managed.     

Antimicrobial drug use in three Canadian general hospitals.

Total amounts of antimicrobial drugs used to treat inpatients during 1975 were calculated for three Canadian general hospitals, one of them the principal teaching hospital of a medical school. Use of drugs was compared with that reported for Boston City Hospital during periods when antimicrobial therapy was and was not supervised by infectious disease consultants. Ampicillin, tetracyclines, cephalosporins, erythromycin and aminoglycosides for prophylactic oral administration were used excessively in the three hospitals. The degree of overuse was comparable to that at Boston City Hospital during years when drug use was uncontrolled. Overuse or improper choice of antimicrobial drug decreases the quality of patient care and increases its cost. More rigorous education is needed for both medical students and practising physicians in the rational use of antimicrobial drugs. Informal consultation with an infectious disease unit should be required before certain overly popular or toxic antibiotics are administered to hospitalized patients.     

Prior Knowledge, Older Age, and Higher Allowance Are Risk Factors for Self-Medication with Antibiotics among University Students in Southern China

Background

Self-medication with antibiotics (SMA) has been reported among university students in many countries, but little research has been done on this issue in China. The objective of this study was to evaluate knowledge and behaviors of university students and risk factors concerning SMA.

Methodology/Principal Findings

Using a novel questionnaire-based data collection instrument, an anonymous online survey was conducted with the students of Shantou University (STU), a university comprising 8 schools/colleges in eastern Guangdong, China. Of 1,300 respondents (13.8% of total eligible participants), 47.8% had self-treated with antibiotics. Logistic regression analysis identified prior knowledge of antibiotics (PKA), older age, and higher monthly allowance as independent risk factors for SMA. PKA significantly influenced students'' knowledge about antibiotics, their uses, and common adverse reactions (all p<0.05). Among self-medicated students, 61.7% used antibiotics at least twice in the previous year. Community pharmacies were the major source of self-prescribed antibiotics. Reported common indications for SMA were sore throat (59.7%), fever (38.2%), cough (37.4%), runny nose (29.3%), and nasal congestion (28.7%). While 74.1% of self-medication episodes were based on students'' own experiences, only 31.1% of students claimed to understand the package insert. Alteration of antibiotics and dosage during the course of self-treatment was made by 63.8% and 55.6% of students, respectively. At least two kinds of antibiotics were simultaneously taken by 82.6% of students. The majority of self-medicated students failed to complete the course of antibiotics. Adverse reactions were reported by 16.3% of students. Amoxicillin was the most common antibiotic used for self-medication.

Conclusions

High prevalence of SMA was noted among STU students. Presence of risk factors and risk-associated behaviors/attitudes in the study population calls for focused educational intervention and stricter governmental legislation and regulation of antibiotic use and sale in pharmacies.     

Resistance to antibacterial drugs of Enterobacteriaceae isolated from healthy children and from those with Salmonella infections

A total of 2329 Enterobacteriaceae strains in bacterial associations isolated from healthy children and children with salmonellosis were tested for their resistance to antimicrobial drugs. It was shown that the aerobic microbial associations isolated from the healthy children contained higher numbers of strains sensitive or resistant to 1-3 antibiotics while the microbial associations from the children patients with salmonellosis treated with antibiotics contained higher numbers of strains resistant to 6-8 antibiotics. Resistance of the aerobic bacterial associations was mainly defined by resistance of E. coli and K. pneumoniae. The feces of the healthy children never treated with antimicrobial drugs contained strains resistant to them. The use of the antibiotics in the treatment led to increasing numbers of the resistant bacteria and changing species composition of the bacterial associations.     

Antibiotic abuse: the testimony of medical students.

Surveys of the use of antimicrobial drugs on students during antimicrobial drugs on students during their first 15 months in medical or dental school indicate that they have been treated with these agents at least three times as frequently as seems reasonable, and that the tetracyclines, ampicillin, penicillin G and erythromycin are the chief drugs overused. Antimicrobiol therapy is frequently instituted for probable viral respiratory tract infections and without any attempt to establish a bacteriologic diagnosis. It is likely that anitmicrobiol agents are used more widely in treating the general public in Canada than in treating medical students. Improvements in the rational use of this important group of drugs could increase the quality and probably reduced the cost of medical care.

The antibiotic resistome: the nexus of chemical and genetic diversity

Over the millennia, microorganisms have evolved evasion strategies to overcome a myriad of chemical and environmental challenges, including antimicrobial drugs. Even before the first clinical use of antibiotics more than 60 years ago, resistant organisms had been isolated. Moreover, the potential problem of the widespread distribution of antibiotic resistant bacteria was recognized by scientists and healthcare specialists from the initial use of these drugs. Why is resistance inevitable and where does it come from? Understanding the molecular diversity that underlies resistance will inform our use of these drugs and guide efforts to develop new efficacious antibiotics.
