Dental fear and premature tooth extraction

Abstract: Dental avoidance is a high risk factor for development of odontophobia and poor oral health including premature tooth extraction in children. The aim of this study is to evaluate the connection between the dental fear and premature tooth loss. Subject of monitoring of the clinical research were 140 school children with mixed dentition. The clinical group consists of 90 children with prematurely extracted teeth. The patients from the clinical group were divided into three groups of 30 patients. The control group consists of 50 children with intact denture. А special questionnaire was filled from the parents of the examined children about the dental fear of their children, whether there is such a fear or not. The results show that while in the control group the majority of children are not afraid of dental treatment – 79,2%, then in groups surveyed more than half of the children said they are afraid of dental treatment, especially the third group – 57,7%. Conclusion: The children with prematurely extracted teeth have a higher level of dental anxiety due to which they are with poor dental health and early tooth loss. The use of behavioural techniques are recommended in order to improve their oral health.

Marine and water-related bio-incidents and preparedness for bioterrorism and biothreats

Abstract: Research and analysis of the conditions for the spread and the eventual outcome of major bio-incidents and epidemic outbreaks as a result of intended/unintended transfer of biological agents by human activity or migration connected with marine and water routes and resources has been conducted in order to assess the necessity to handle that kind of events. Several cases related to marine bio-incidents, which have caused or could have caused many casualties, have been considered; possibilities for the spread of such incidents, the conditions for their spread as a result of intended/unintended transfer of bioagents by human activity or migration connected with marine and water routes and resources as well as their potential to affect and the scope of possible damage. According to many researchers, the bioterrorism threat can be compared to а nuclear threat, which has persisted for the last 50 years, with the only difference that there are no effective strategies for handling a bio threat, as compared to the nuclear one. Investments in defence strategies aimed at bioattack could save million lives and the economy from collapse by means of the three defence measures, which have proved the most promising in handling a bioterrorist attack: 1. early bioattack warning systems – BAWS; 2. systems for surveillance of the environment by means of which bioagents could be effectively discovered and identified within hours, installing those near important internal locations, in and around seaports, as well as other critical infrastructure; 3. readiness for the biomedical treatment to reach anyone directly exposed to any bioagents identified by BAWS. Providing adequate safety measures to handle bioattack is a necessary step to guarantee security of sea transport, in particular, but also of national security and global security as a whole.

Development of treatment protocol with selective laser melted fixed partial dentures

Abstract: Purpose: of the present paper is to offer treatment protocol with fixed partial dentures, produced by selective laser melting, including clinical and laboratory parts. Design/methodology/approach: The treatment protocols with selective laser melted fixed partial dentures was developed on the basis of literature survey and our previous research about accuracy and mechanical properties of dental bridges, manufactured by additive technologies. Findings: The treatment protocol with fixed partial dentures, produced by selective laser melting, consisting of clinical and laboratory parts, was developed. The treatment procedures with FPD made by SLM were classified as semi-digital when working with extraoral scanner and fully-digital – with intraoral scanner. Research limitations/implications: The introduction of the proposed treatment protocol into the clinical and laboratory practice would lead to a systematic approach and working optimization for prosthodontists and dental technicians when using selective laser melting. Practical implications: Due to the elimination of multiple manual manipulations and technological operations, treatment protocols with FPD, produced by SLM, ensure higher accuracy and quality of the constructions and shorter time for their manufacturing compared to the conventional procedure. Originality/value: The developed clinical and laboratory protocols for the treatment and manufacturing of FPD through SLM clearly show the benefits of the new technology in dentistry and dental technician field.

Hemolytic Uremic Syndrome - Pathogenesis And Laboratory

Abstract: Introduction: Our interest was provoked by a patient who, after intestinal inflammation accompanied by acute diarrheal syndrome, had sharply elevated urea levels, creatinine, uric acid and potassium in the blood, indirect bilirubin and lactate dehydrogenase (LDH). Peripheral blood pacing (PKK) automated analysis revealed anemia with a platelet count of less than 100x10 / 9 / L and a morphological analysis of blood smears on Romanowsky-Giemsa staining showed the presence of schizocytic forms of the cells of the erythrocyte line. Materials and Methods: As a material, we used whole blood taken with an EDTA anticoagulant, tested on a Mindray-BC-3000Plus automatic hematological counter, and a blood smear stained by Romanowsky-Giemsa, as well as blood for biochemical analysis, which we studied with a biochemical analyzer Roche - Cobas Integra 400Plus. Results and Discussion: Laboratory results of hemolytic anemia, thrombocytopenia and acute renal failure (ARF), combined with the clinical picture of the patient, have led us to the diagnosis of hemolytic uremic syndrome (HUS). Conclusion: When combined with the indicated clinic and laboratory findings, it is always necessary to think of a differential diagnostic plan for HUS. HUS is characterized by recurrent episodes of acute disease leading to terminal renal failure.

Some causes that hinder the prophylaxis of breast cancer

Abstract: Introduction: Prophylaxis of breast cancer is one of the most important measures to limit this disease. Finding and eliminating the reasons, leading to its deterioration ensures its success. Purpose: To identify some of the reasons that lead to difficulties in breast cancer prevention in women. Material and methods: 1102 women aged 20-65 live in the regions - Varna, Dobrich, Silistra and Shumen. The survey covers the period January 2013 - March 2015. Sociological methods - document analysis, survey method; statistical methods. A personal (questionnaire) is used for conducting the survey. The data were statistically processed through SPSS v. 20.0 and are represented graphically. Results and Discussion: The study shows that only 47.50% of the respondents had been involved in breast cancer prevention. There is a difference in the proportion of prophylactic examinations in different age groups (I‡2 = 37,38; p<0,001). The results show that women above 46 years are more often involved in breast prophylaxis. It was found that women with a lower level of education were seen much less often than those with college and university education. Another significant cause of the prophylaxis of this type of cancer is the place of residence, with roughly half (49.10%) of the respondents in rural areas not conducting such examinations. Nearly half (49.60%) of women said they had difficulty performing prophylactic breast examinations that prevented them from participating in prevention. Nonetheless, respondents stated serious readiness to participate in the ongoing breast cancer prevention.
