Abstract Background: Lacuna anatomy has been studied widely in various organs to improve the operative approach and surgical procedure. However, there are few studies about the peri-esophageal lacuna (PEL). The aim of this study was to describe minimally invasive esophagectomy (MIE) with a focus on PEL anatomy.Methods: From August 2012 to December 2015, patients with esophageal carcinoma underwent MIE by the same group of surgeons at our institution. A double lumen endotracheal tube was used with left lung ventilation without pneumothorax for patients in group 1. A single lumen endotracheal tube was used with two-lung ventilation and right artificial pneumothorax for patients in group 2. The methods that we used for thoracic esophagus mobilization and modularized lymph node dissection, based on the American joint committee on cancer (AJCC) staging manual, in the peri-esophageal space are described. We evaluated the surgical effect, postoperative complications and follow-up results.Results: A total of 147 patients (107 men; mean ± standard deviation age 63.1 ± 7.7 years) were enrolled. Among them, 67 were placed in group 1 and 80 in group 2. There was no significant difference between the two groups in terms of age, gender, tumor location, T stage, N stage or comorbidities. The mean operation duration (283±46 vs 307±69 minutes; p=0.007) and blood loss (129±84 vs 260±225 mL; p=0.000) was less in group 2 than group 1. Group 2 also yielded a larger number of lymph nodes compared with group 1 (22.5 ± 11.1 vs 16.4 ± 7.4; p=0.007). Complication rates were similar between the two groups, with hoarseness developing in a significantly smaller number of patients in group 1 than group 2 (1% vs 21%; p=0.000). There was no significant difference between the two groups in one-year (78.3% vs 84.2%; p=0.345) and three-year (52.1% vs 62.7%; p=0.210) survival rates for group 1 (a double lumen endotracheal tube with left lung ventilation without pneumothorax) versus group 2 (a single lumen endotracheal tube with two-lung ventilation and right artificial pneumothorax).Conclusion: Esophageal mobilization based on PEL and the modularized lymph node dissection based on the AJCC cancer staging manual improves surgical outcomes.

Abstract Background Elderly patients undergoing gastrointestinal surgery are at higher risk for postoperative complications and mortality. Currently available literature on elderly patients undergoing an esophagectomy is inconclusive and dates back from the time before minimally invasive techniques were implemented. Methods Length of hospital stay, 90-day morbidity and mortality were analyzed from patients undergoing minimally invasive esophagectomy (MIE) between 2014 and 2017 in a single center. Data from patients aged 76 years or older was compared to the cohort of patients aged 71 to 75 years old. Results From a consecutive series of in total 187 patients two cohorts were retrieved: 19 patients 76 years or older (group 1) were compared to 41 patients 71 to 75 years old (group 2). Median age was 77 years (76–83) in group 1 and 72 years (71–75) in group 2 (P < 0.05). There were no significant differences in sex, Charlson comorbidity score, number of patients undergoing neoadjuvant chemoradiaton, histological tumor type, tumor stage, number of lymph nodes harvested and type of anastomosis. There were no significant differences in length of hospital stay, 90-day morbidity and mortality. The percentage of anastomotic leakage was 21.2% in group 1 and 14.6% in group 2. Mortality was 10.5% and 4.9% respectively. Conclusion No difference was seen in morbidity and mortality after MIE comparing the eldest old to younger old patients. Therefore, patient selection should not be based on calendar age alone. Disclosure All authors have declared no conflicts of interest.

Background: To compare the efficacy of saline, lignocaine 2% and Lignocaine 4% in the endotracheal tube cuff to decrease the incidence of post operative cough and sore throat. A unique, efficient and easy method designed to decrease cough and sore throat during emergence. Hence there was a need for the study. Methods: After approval from institutional Ethical Committee, Kasturba Medical college, Mangaluru and written informed consent from 120 patients of A.S.A class I & II, aged between 18-60 years posted for various surgeries were included. Randomization was done into three groups of 40 patients each. Group 1 – Normal saline, group 2 - 2% Lignocaine and group 3 - 4% Lignocaine. Postoperatively patients were assessed for incidence of cough and sore throat pain based on visual analogue scale (VAS) Results: 65% of patients in group 2 and 72% of patients in group 3 were extubated smoothly, whereas only 20% of patients in group 1 had smooth extubation, p<0.001. There was significant difference in sore throat pain and cough in group 2 and 3 when compared to group 1. Conclusion: The incidence of sore throat and cough was significantly reduced with Lignocaine in the endotracheal tube cuff when compared to saline. Lignocaine 4% was found to be far more better than 2% in reducing sore throat.

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.

Decline in normal physiological pulmonary function has been attributed to premorbid conditions such as prehypertension. Research evidence suggests that physical activity reduces age-related decline in pulmonary function and improves the efficiency of the lungs in prehypertensive patients. However, there is a scarcity of data evidence relating to isometric exercise and pulmonary function. Furthermore, the interrelationship between the intensity and duration of isometric exercise and pulmonary function in these patients is still uncertain. Therefore, this study was undertaken to investigate the effect of isometric handgrip exercise on pulmonary function capacity in adults with prehypertension. To determine the effectiveness of isometric handgrip exercise on pulmonary function capacity in adults with prehypertension. A quasi experiment using a pre- and post-exercise method was carried out in two out-patients hospital settings. The sample comprised 192 sedentary pre-hypertensive subjects, aged between 30–50 years, that were randomly distributed into three groups of 64 participants each. The subjects performed, for 24 consecutive days, an isometric handgrip exercise at 30% Maximum Voluntary Contraction (M.V.C.). At the end of the 24 days, group one (GP1) discontinued, while group two (GP2) continued the exercise protocol for another 24 consecutive days and group three (GP3) continued with the exercise protocol for another 24 consecutive days but at 50% M.V.C. Determinants of lung function (outcomes) were Forced Expiratory Volume in 1 s (FEV1), Forced Vital Capacity (FVC), FEV1/FVC Ratio and Peak Expiratory Flow Rate (PEFR). The study shows that there was no statistically significant difference in the pre- and post-exercise outcomes for FEV1, FVC, FEV1/FVC Ratio and PEFR after 24 days for group 1. In group 2, there was a statistically significant difference in the FVC [(mean = 0.12 ± 0.12), (p = 0.002)], FEV1 [(mean = 0.15 ± 0.17), (p = 0.003)] and PEF [(mean = 0.85 ± 0.35), (p = 0.001)] after 48 days. In group 3, there was a statistically significant difference (p = 0.001) in all the outcomes assessed after 48 days. There was a between groups difference in favour of group 2 compared with group 1 for outcomes of FEV1 [(mean = 0.142 ± 0.68), (p = 0.005)] and PEF [(mean = 0.83 ± 0.19), (p = 0.0031)]. There was statistically significant difference in favour of group 3 compared to group 2, by increasing the exercise intensity from 30% to 50% M.V.C., for outcomes of FVC [mean change = 0.10 ± 0.052), (p = 0.005)], FEV1/FVC [mean change = 3.18 ± 0.75), (p = 0.017)] and PEF [(mean change = 0.86 ± 0.35), (p = 0.001)] after 48 days. Isometric handgrip exercise (after 48 days at 30% to 50% M.V.C.) improves outcomes of pulmonary function capacity in adults with prehypertension. Meanwhile, duration and/or increase in intensity of the isometric effort significantly contributed to the affects attained.
