Antimicrobial therapy (AMT) is one of the principal problems in practice of the modern dentist. Mass visits to doctors for dental care, the prevalence of dental diseases among people from all walks of life, a unique quantitative and qualitative composition of the oral microflora, uncontrolled use of antimicrobials by patients results in increased resistance of microorganisms to antimicrobial medicines and increased number of cross-infection among dental office visitors. This article highlights the results of the study designed to assess knowledge of senior dental students of medical schools and dental residents on the main issues of antibiotic therapy and the empirical use of antimicrobials for treatment of respiratory disorders. Dental students of Belgorod have come into the study. According to the inquiry, 21.2% of dental students and 12.8% of dental residents were able to correctly choose the pharmacological group of antibiotics. 47.5% of students and 43.8% of residents decided to change the antibiotic due to the absence of clinical response within two to three days. 35% of dental students and 37.5% of the dental residents re-inquired believe that antibiotics should be replaced even in case of the positive result from their use. 16.7% of dental students managed to correctly choose all pharmacologically irrational combinations of antimicrobials, 17.2% of dental residents answered correctly after having been re-inquired. 25.6% of students and 31.2% of residents managed to completely make the empirical assignment of the AMT in case of respiratory infection. Only 50% of students and 62.5% of residents decided that their knowledge of the AMT is insufficient for the future work in the field of health care, and they need to make additional educational efforts related to the topic.
Introduction: Over the past few years, the incidence of retinal ischemic disorders has been increasing, due to a rising prevalence of such socially burdensome diseases as diabetes and hypertension, which ultimately lead to ocular vascular pathology. The identification of new treatment options that would prevent retinal neuron death is a crucial task of modern pharmacology.
Materials and methods: The research was carried out on male Wistar rats. Retinopathy was modeled by inducing a 30-min ischemic episode, with a 72-hour period of reperfusion and subsequent administration of Retinalamin and Emoxypine for 10 days. The effectiveness of the drugs was evaluated by electroretinographic, ophthalmoscopic and morphological assessments.
Results and discussion: On Day 14 of the experiment, a dose-dependent preservation of the electroretinogram b-wave/a-wave amplitude ratio was observed in the animals treated with Retinalamin depending on a dose (1.39±0.06, 1.46±0.03 and 1.49±0.04 in low (0.214 mg/kg), medium (0.428 mg/kg) and high (0.857 mg/kg) Retinalamin dose groups, respectively). The ophthalmoscopic picture of the fundus oculi also improved following the treatment with Retinalamin (1.42, 1.69 and 1.90 times lower ophthalmoscopic scores compared to placebo-treated animals in low, medium and high dose groups, respectively). The morphologic “coefficient of change” applied to ganglion cell layer was 2.2, 1.7 and 1.6 points in low, medium and high dose Retinalamin groups, respectively. These results are significantly different from both intact and placebo group (p<0.05). Based on the aforementioned experimental findings, we conclude that Retinalamin has a retinoprotective effect and is superior to the drug of comparison (Emoxypine).
Conclusion: The greatest neuroprotective effects were shown in the groups receiving Retinalamin. In these groups, the ERG b-wave/a-wave amplitude ratio was preserved, the ophthalmoscopic picture was less pathologic and retinal morphology features were close to those of the intact retina.
Introduction. Community-acquired pneumonia (CAP) remains one of the most acute problems of bronchopulmonary pathology being the 4th in the mortality structure (after cardiovascular, cerebrovascular diseases and malignant neoplasms) and the 1st among all fatalities from infectious diseases. Thanks to the scientific progress achieved in the antibiotic therapy and vaccine prophylaxis, the death toll has decreased four times compared to its rate during the “pre-antibiotic era“. However, nowadays there is a steadily increasing trend in the pneumonia mortality rate in Russia. The only possible way to increase efficacy of CAP treatment is timely initiated rational antibiotic therapy, considering the possible etiologies, risk factors and the severity of the patient’s condition.
Materials and methods. The article represents the results of anonymous prospective surveys within the framework of the KNOCAP multi-centered research project aimed at accessing the knowledge on the fundamental issues in diagnosis and treatment of community-acquired pneumonia. The survey involved 222 students in their fifth- and sixth years in medical institute from Belgorod, Dnepr (Dnipro), Voronezh, Kiev (Kyiv) and Saratov and 110 physicians from Krasnodar, Saratov, Belgorod and Dnepr.
Results and discussion. According to the results of the survey, such levels of correct answers were given by doctors and students, respectively: the inadmissibility of antimicrobial therapy (AMT) delay in CAP - 82% and 59%; the main criterion for withholding AMT - 56% and 37%; “sequential therapy” - 61% and 59%. At the same time, only 24% of the students and 23% of the physicians surveyed correctly reported typical mistakes in the treatment of a non-severe CAP with 50% or more accuracy; and in case of initial treatment, the number of correct responses was less than 28% for students and 45% for doctors.
Conclusion. The survey showed that both senior medical students majoring in Medical Care and general practitioners had a low level of knowledge in CAP treatment. Hence, curricula need to be adjusted both in medical universities and in health institutions for practitioners in order to inform them and, thus, improve the quality of their knowledge in this field.
