1. We focused on 175 patients operated on for otosclerosis. There were 89 in group 1 (preoperative 4000 Hz BC threshold better than 2000 Hz) and 86 in group 2 (preoperative 2000 Hz BC threshold better than 4000 Hz). 2. Preoperatively, there was no significant difference in terms of average bone conduction (BC) thresholds, average air conduction (AC) thresholds and air-bone gap (ABG) between the two groups. 3. Three months and 1 year after surgery, group 1 had better audiometric outcomes than group 2 in terms of average AC and BC thresholds and ABG. 4. Postoperative BC gain was better in group 1 than group 2, particularly at 500 Hz, 1000 Hz and 2000 Hz. 5. When the 4000 Hz BC threshold was preoperatively impaired (group 2), it was not worsened after stapes surgery. This was not the case in group 1.

Objective. The aim of this study is to analyze the hearing and vestibular outcome of patients with otosclerosis who have been operated on by fiber optic flexible CO2laser.Study Design. A preliminary and retrospective study was conducted in 30 patients with otosclerosis.Results. Comparative analysis of average air conduction thresholds (53.41±11.81 dB versus26.37±11.04 dB) and air-bone gaps (34±9.92 dB versus12.03±6.02 dB) before and after the surgery were statistically significant (<0.001). Air-bone gap closed within 10 dB or less in 50% of the cases and within 20 dB or less in 90% of the cases. Average bone conduction threshold after the surgery (16.68±12.00 dB) was better than that before the surgery (20.13±8.59). However, no statistically significant difference was found (p=0.213). One patient had tinnitus after surgery. None of the patients had severe sickness or vomiting due to surgery. Eleven patients (36.6%) had very mild nystagmus beating toward the counter-lateral side. All patients were stable at 10 days after surgery.Conclusion. The results indicate that fiber optic flexible CO2laser provides the surgeon with a very safe and precise surgical instrumentation even in cases with extensive and obliterative otosclerosis.

Eighteen canine mandibular premolars were divided into 3 groups. In group 1, implants were inserted in periapical lesions. In group 2, implants were inserted when lesions were radiographically healed. In group 3 (control), implants were inserted immediately after extraction. There was no significant difference in average bone implant contact between the 3 groups. Considering the limitations of this study, immediate placement of dental implants in tooth sockets with periapical lesions should be proposed only under special circumstances.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

The clinic and diagnostics of tuberculosis meningitis (TM) in 926 patients treated in St. Petersburg hospitals in 1965–1994 (group 1) and in 1995–2018 (group 2) is presented. The TM clinic is demonstrated to be determined by the form of tuberculosis and its characteristic generalization nature in the presence of repeated waves of bacteremia and allergic vasculitis of greater or lesser severity. There is clinical peculiarity of TM in primary pulmonary tuberculosis and its early large-focal and late miliar generalization, as well as in hematogenous tuberculosis. In patients of the 1st and 2nd groups the TM clinic shows in some respects a noticeable similarity, in others — a significant difference. Despite the typical symptoms, early diagnosis of TM took place in less than 20% of patients. Clinical examples illustrating the unusual development of TM, contrasting with its usual course, are given. A number of objective and subjective factors contributing to the adverse evolution of TM and its lethal outcome are discussed. These include the peculiarity of modern tuberculosis, especially when associated with HIV infection, as well as medical errors associated with ignorance of the pathogenesis of tuberculosis and failure to comply with the minimum examination for tuberculosis.

This study evaluates and compares by dye penetration method and SEM photomicrographs the sealing obtained using two different classes of adhesive systems (etch-and-rinse and self-etch with selective etching) with SDR (Dentsply) bulk fill composite. 84 class V cavities were prepared on oral and vestibular face of 42 intact, freshly extracted wisdom teeth. The cavities were randomly divided in two groups and restored: Group 1 with prime &bond one select (Dentsply) and SDR (Dentsply) and Group 2 with prime&bond one Etch&Rinse (Dentsply) and SDR (Dentsply). Prime&bond one Select (Dentsply) is a single component adhesive and can be used in self etch mode, in selective enamel etch mode, or in etch-and-rinse mode. We chosen for this study the selective etch of the enamel mode. Prime&bond one Etch Rinse (Dentsply) is a universal etch-and-rinse one-bottle dental adhesive, designed to be used in two steps. The bulk fill composites are commonly used in modern dentistry due to their properties of low polymerization shrinkage and curing in layer of 4 mm depth, offering the practitioner a fast clinical procedure with good results. The results showed a good sealing at enamel and dentin margins with no statistically significant difference between adhesives, even though the mean of enamel infiltration was smaller for Group1. Furthermore the results show that there were differences between the two groups, for the infiltrations at the enamel, the values of microleakage being arithmetically higher for Group 1, but with no statistically difference between the two groups.SEM images showed for both groups a good adhesion surface with the tooth, but the hybrid layer of the total-etch adhesives is different from the hybrid layer formed by self etch adhesives, in terms of thickness, uniformity. In conclusion both adhesive systems have equivalent sealing qualities and can be successfully used with SDR.

BACKGROUND Gingivitis is a non-painful, inflammatory condition that can be treated with home remedies. Left untreated gingivitis can lead to tooth loss. Periodic dental examinations are important for early diagnosis and treatment of gum diseases. In order to contain the spread of the corona virus, governments, including in Israel, have restricted movements of their citizens which has caused routine dental checkups to be postponed. OBJECTIVE This study aimed to examine the ability of an mHealth app- iGAM to reduce gingivitis. METHODS A prospective observational cohort study was performed, 160 unpaid participants were divided into 2 equal groups and downloaded the iGAM app. Group 1 photographed their gums weekly for eight weeks. Group 2 photographed their gums at the time of recruitment and 8 weeks later. After photo submission, the participants received the message "It is recommended to read the information contained within the app regarding maintaining oral hygiene habits". A single blinded researcher examined the images and scored them according to the Modified Gingival Index (MGI). RESULTS The average age of group 1 was 26.77 (S.D. ± 7.43), and 28.53 (S.D. ± 10.44) for group 2. The majority were male (74.7% in group 1 vs. 66.7% in group 2), most participants described themselves as "secular", most were "single", non-smokers (74.7% vs. 78.4%) and did not take medications (85.3% vs. 78.4%). 126 subjects completed the study. A statistically significant difference (P <.001) was found in the dependent variable (MGI) in a linearly negative manner. As time passed, the gum condition improved, there were significantly lower gingivitis scores in group 1 (M = 1.16, S.D. ± 1.18) compared to group 2 (M = 2.16, S.D. ± 1.49), after eight weeks. Those with more recent dental visits had a lower MGI (p = .037). No association was found between knowledge and behavior, most participants were familiar with the recommendations for maintaining oral health, yet they only performed some. CONCLUSIONS A dental selfie taken once a week using an mHealth app (iGAM) reduced the signs of gingivitis and promoted oral health. During the current pandemic where social distancing recommendations may be causing people to avoid dental clinics, this app can remotely promote gum health. CLINICALTRIAL The protocol was approved by Hadassah research ethics committee (IRB, 0212-18-HMO)

Purpose. To compare the capsule edges ultrastructure obtained by two femtosecond laser-assisted cataract surgery (FLACS) platforms and manual continuous curvilinear capsulorhexis (CCC) using scanning electron microscopy (SEM). Setting. Eye Clinic, University of Trieste, Italy. Design. Experimental comparative study. Methods. 150 anterior capsules were collected and divided into three groups as follows: Group 1 (50 capsules) obtained with manual CCC, Groups 2 and 3 (each with 50 capsules) obtained with the Catalys Laser and the LenSx Laser, respectively. All samples were imaged by means of SEM and regularity of the cut surface, and thickness of the capsule edge were evaluated and compared. Results. All femtosecond laser (FSL) capsules were perfectly circular, whereas some alteration of the circular shape was observed in the manual ones. Group 1 showed a smooth and regular capsule edge without any surface irregularity, conversely Groups 2 and 3 showed postage-stamp perforations on the capsule edge. The cut surface irregularity value in Group 2 was 1.4 ± 0.63, while it was 0.7 ± 0.49 in Group 3 (p<0.05). Group 1 had a significantly lower thickness of the capsule edge than the FSL groups (p<0.05). No statistically significant difference in the capsule edge thickness between the FSL groups was found (p=0.244). Conclusions. Despite the presence of slight cut surface irregularities, both FSL capsulotomies showed a better geometry and circularity than the manual ones. Capsulotomy specimens obtained using both FSL capsulotomies showed laser-induced alterations of the capsule edge when compared with smooth and regular edges obtained using manual CCC.
