Provision of quality health services to population of the rural areas with limited access to dental treatment and educating dental students in high standard of professional conduct when delivering health services to the population, represents the main reason for the foundation of a dental college in an area like Mangalore. The purpose of this study was to assess the satisfaction of patients visiting the dental college clinics. A cross-sectional study was conducted between May 1 and July 31, 2017. A questionnaire, covering 4 items: patient-dentist relationship; efficiency of the general clinic; patients perception of dental care quality; college healthcare opinion, was distributed to 400 patients visiting the dental clinic. Data were treated statistically using overall percentage distributions and Fisher exact test. The mean percentage of agreement for the 4 items was 85.86 ± 24.51% denoting a high level of satisfaction. Fisher exact test showed (p < 0.01) statistically important difference between first time and multiple time visitors answers. Majority of the patients were satisfied with the clinical settings and the benefits of the fast delivered treatment. The quality of the services was appreciated by the majority of visitors. The attitude of the providers of healthcare was perceived as very friendly and gentle. The assessment of patients’ contentment and perception of healthcare services could be an efficient tool to evaluate the overall activity of an educational healthcare institution.
Closure of skins and soft tissue defects is a mainstream procedure in the field of reconstructive plastic surgery. Nowadays plenty of reconstructive options exists in the armamentarium of the specialty. The “keystone island perforator flap” is a relatively new conception which consists of taking skin and superficial fascia in a keystone pattern adjacent to the defect that needs to be covered. This technique is based on the most contemporary knowledge of the vascularization and three-dimensional vascular architecture of the skin and soft tissue overlying the bones - the so called angiosomes and perforasomes concepts. In the present article a brief review of the main keystone fl ap types and on their predecessor - the Bezier flap, was made. Two clinical cases with difficult defects on the limbs are presented and discussed in order to illustrate the application of that approach. The keystone perforator island flaps is a sophisticated and relatively easy option for defect closure. However, this surgical concept still remains unpopular in the Bulgarian practice and science of plastic surgery. To the best of our knowledge this paper is the first one focused on the topic.

The aim of the present study was to provide alternative means of measurement and evaluation of muscle strength in rehabilitation practice and diagnostics. In the last few years many electronic devices for evaluation of muscle strength have developed. Contemporary studies have shown that in addition to the standard manual muscle testing muscle strength can be assessed more objectively and analytically using electronic dynamometers and equipment. The strain gauges are used as a tool of precision in the industry that allows measurement of mechanical loads by dynamometers. By using these tools is possible to obtain continuous digital measurement and recording of muscle strength.
Hairline is a crucial landmark in facial aesthetics. Its restoration in terms of position, continuity and hair growth is of a paramount importance in facial plastic aesthetic and reconstructive surgery. The purpose of the paper is to demonstrate the effectiveness of using local tissue only in the restoration of skin and soft tissue defects affecting the hair-line. A brief retrospective analysis of clinical cases with defects engaging the hairline was made. The majority of the patients (20 out of 22) were operated because of skin lesions of different entities. In 7 of the cases the direct closure technique was applied as a surgical tool for hairline restoration and in 15 of them rotational flaps were the best reconstructive option. A special emphasis is put on the defect size in regards of choosing the right surgical technique for defect closure in order to achieve the best aesthetic outcome in the hairline restoration.

The laser coagulation at the apical part of the root canal after vital extirpation is a proper method of preventing complications such as pain, bleeding, remaining vital pulp. The aim of the present survey is to register the thermal changes that occur on the tooth surfaces during laser treatment of the root canal after vital extirpation. An in vitro study of 30 extracted teeth has been conducted. The teeth have been prepared with ProTaper nickel-titanium machine tools and wiped dry. During the course of laser treatment of root canals with a diode laser DenLase temperatures, changes of the surface of the hard dental tissues have been recorded with infrared camera FLIR T330. The captured thermal images have been processed with software product Flir Reporter Pro 9. In conclusion, temperature changes in hard dental tissues at diode laser treatment of the root canal are biocompatible.

Hepcidin is a 25-aminoacid cysteine-rich iron regulating peptide. Hepcidin quantification in human blood may provide further insights for the pathogenesis of disorders of iron homeostasis and might prove a valuable tool for clinicians for the differential diagnosis of anaemia. This study describes ELISA immunoassay for hepcidin quantification in human serum. We used a sandwich ELISA method from USCN Life Science inc., that consists of ready to use, pre-coated 96-well strip plate with 2 antihepcidin-25 monoclonal antibodies. A recombinant hepcidin in 16 μg/l concentration is used as a standard; it reconstitutes with 1.0 ml standard diluent to prepare a stock solution. We correlated ELISA results of hepcidin-25 measurements in healthy population with hemodialysis patients. The sandwich ELISA was highly specific for hepcidin-25, having a low limit of quantification of 0.020 μg/l. Hepcidin- 25 concentrations were increased in hemodialysis patients (median 33.05 μg/l, range 22.31 -60.98 μg/l, n = 10) compared with healthy individuals (median 12.41 μg/l, range 6.05-18.53 μg/l, n = 40). The use of 2 monoclonal antibodies in a sandwich ELISA format provides a robust, convenient and not very expensive method for measuring concentrations of the active form of hepcidin. It should help to improve our understanding of the role of hepcidin in regulating iron metabolism.
Positron Emission Tomography (PET) is an important cancer imaging tool, both for diagnosing and staging, as well as offering predictive information based on response. PET is a nuclear medicine imaging technique which produces a three-dimensional image of functional processes in the body. While PET is commonly used to detect the tumors, especially in breast, colon, lung and for lymphoma, as well in the last decade it is verified as considerably more accurate than Computed Tomography (CT) in the distinction between benign and malignant lesions. PET is not only more accurate than conventional imaging for the assessment of therapy response, but also it is useful to detect some viable tumor cells after treatment. However, motion is a source of artifacts in the medical imaging and results in reducing the quantitative and qualitative accuracy of the image. In general during the procedure of PET scanning, a few types of motion can occur that should be corrected and compensated. Different body motions are classified as brain motion, cardiac motion and respiratory motion. In this study, some of the most important motion correction and compensation methods using PET imaging system are compared.
Chronic periodontitis is a result of polymicrobial infection and its treatment aims removal of dental calculus and biofi lm from the periodontal pocket. Many hand and power-driven instruments are created for this purpose. In recent years, lasers are widely discussed tools for periodontal therapy. The aim of the present study is to evaluate the early microbiological and clinical effectiveness of the Er:YAG laser in the treatment of chronic periodontitis. 30 patients with moderate chronic periodontitis were enrolled in the study. Using a split-mouth design they were treated either with Er:YAG laser (chisel tip, 100 mJ, 15 Hz, 5-6 water spray)-test group or with Gracey curettes- control group. Probing pocket depth (PPD), gingival recession (GR), clinical attachment level (CAL), bleeding on probing and plaque presence were evaluated at baseline and one month after the therapy. Microbiological samples were taken from the deepest four pockets of each quadrant from 20 randomly selected patients (n = 80). They were evaluated using real time PCR for periodontal pathogens from the red complex (Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia). One month after therapy in the control group PPD decreased from 4.59 mm to 3.36 mm, the CAL gain was 1.09 mm and the reduction of bleeding and plaque - from 87.9% to 33.7% and from 75.9% to 40.9%, respectively. In the test group PPD decreased from 4.58 mm to 3.15 mm, the CAL gain was 1.37mm and the reduction of bleeding and plaque was from 85.6% to 25.9% one month after the treatment. The results were statistically significant in favour of the laser group (p < 0.05). Microbiological analysis revealed that the pathogens from the red complex decreased 3 times in the control and 6 times in the test group. Therefore, the Er:YAG laser demonstrate pronounced early effectiveness in chronic periodontitis treatment and would be appropriate alternative of the conventional periodontal therapy.
