The study aims to evaluatethe bacteriological profile of the surgical site infections at the Clinic of Oral and Maxillofacial Surgery of the Sf.Spiridon Clinical Hospital in Iasi, Romania between 2011 and 2018. Microbiological data were obtained from the Microbiology Laboratory of the Sf.Spiridon Emergency Clinical Hospital Iasi. 125 surgical site infections, accounting for 54,1% of health care associated infections were reported in 106 patients, representing 66,6% of the patients with HAI. The most commonly identified pathogens were Klebsiella Pneumoniae, Staphylococcus aureus, Acinetobacter baumanii and Pseudomonas aeruginosa.A high level of antibiotic resistance was reported. Prevention of SSI and antibiotic resistance control are complex and require coordinated measures in view of an integrated, multidisciplinary approach.

The aim of the present study was to assess the remineralizing potential of 10% casein phosphopeptide-amorphous calcium phosphate complex (CPP-ACP) -Recaldent used alone or with fluoride (CPP-ACFP) as compared to fluoride mouthrinse for the non-invasive treatment of occlusal non-cavitary caries lesions in vivo.A total of eighty subjects were randomly assigned to four groups, i.e. group 1 - 10% CPP-ACP, group 2- 10% CPP-ACP + 0.2% NaF, group 3- 0.05% NaF mouthrinse and group 4 �control. The lesions were assessed using visual examination and DIAGNOdent measurements. After 12 weeks of using the corresponding product, the results showed that the highest decrease in fluorescence was produced by CPP-ACFP (from 16.28�1.40 to 6.53�0.59, p=0.002), followed by CPP-ACP (from 15.70�1.82 to 8.18�0.70, p=0.004) and fluoride mouthrinse (from 14.32�1.72 to 7.88�0.68, p=0.005), significantly higher than in the control group (p[0.05). No significant differences were found between the three treatment groups.

Background and Objectives: The basis of any infection control program is hand hygiene (HH). The aim of this study was to investigate knowledge of HH among medical students. Materials and Methods: Students were randomly selected from two Romanian universities and a cross-sectional, questionnaire-based study was conducted between January and May 2021. The answers regarding demographic data and knowledge concerning the methods, the time and the antiseptics used for HH were collected. The selection of the study group was made according to selection criteria in accordance with ethical issues. A descriptive statistical analysis was performed, and a chi-square test was used for data comparison, with a cut-off point of 0.05 for statistical significance. Results: The results indicated that the attitude of the students towards the practice of HH improved significantly. Most students believe that simple HH can control infections. Significant differences were found by the year of study in terms of the hand surfaces included and recommended duration (p < 0.05). Conclusions: In conclusion, the study shows that most respondents have sufficient knowledge on HH, meaning that a higher compliance is required to control infections. The indicated reasons of non-compliance with HH are emergencies and other priorities.

The aim of the present study was to assess the attitude of students attending 4th and 6th year of the Faculty of Dental Medicine in Iasi towards HIV-seropositive patients. A questionnaire was elaborated, containing 14 ethic statements related to some aspects they may encounter in their future career: the observance of confidentiality and the rights of HIV/AIDS infected patients, the refusal of dedicated treatment and the appreciation of discrimination in this situation. The results have identified some negative aspects regarding the above mentioned issues, mainly in terms of the refusal of specialized treatment. A percentage between 47.4% and 38.4% of the students strongly agreed to the affirmations according to which the risk of cross-infection and the lack of some safety conditions at work may be a reason for the refusal to provide dental treatment. The responses referring to discrimination suggest that there is a negative attitude towards the following aspects: the treatment of HIV-infected patients in different offices, the refusal to continue treatment after confirmation of the diagnosis, the refusal to cooperate with an infected colleague. Only 57.8% of the subjects considered the refusal of treatment as discrimination, with no statistical differences between the years of study. The results suggest both the need to modify the academic curriculum by introducing some ethics and medical legislation courses, and the adoption of a strategy for the increase of empathy and social responsibility in relation to this group of discriminated persons.

The aim of study was to investigate the relationship between oral health and nutritional status in a population of elderly patients with systemic chronic or acute pathology. Materials and method: Prospective cross-sectional clinical investigation of 115 aged patients (] 60 yo; mean age 66.2) from the Clinical Foundation, Faculty of Dental Medicine, University of Medicine and Pharmacy of Iasi. In the first stage of the study, the patients (able to understand and communicate) were submitted to a mini-test for the assessment of the mental status (MMSE) . In the second stage of the study, a questionnaire was used to record demographic and socioeconomic data of the subjects as well as information regarding systemic status and nutritional facts. In the third stage of the study, the nutritional status was evaluated by using Mini-Nutritional Assessment questionnaire (MNA). Finally, the oral status was evaluated by using clinical and radiographical exams as well as geriatric oral health assessment index (GOHAI). Results: Of the 60 old adults, 6% were severely malnourished, and 37.4% presented malnourished risk. 49.6% of the old people had difficulties eating firm foods, 25% of them being unable to prepare meals. Regarding oral status, only 5.2% had at least 20 natural teeth, 55.6% required dental care for decayed or broken teeth, 69.6% were affected by xerostomia, 21% of the completely or partial edentulous people were untreated by removable dentures, 25% of the edentulous patients complained by ill-fitted removable dentures. Conclusion: Lack of education, treatment with over 3 drugs daily, physical inability to buy foods or to prepare meals, as well as the difficulties eating firm foods are strongly associated with poor nutritional status. Also, the need for dental care was associated to nutritional deficiency.
