Purposes: (1) To determine the microtensile bond strength (μTBS) of self-adhesive (SA) composite cements to unetched/etched enamel and dentin, and (2) to characterize the cements' interaction with tooth tissue. Methods: 51 composite blocks were bonded to smear layer-covered enamel and dentin (three teeth per group). Four SA composite cements (Clearfil SA, G-CEM, RelyX Unicem, SmartCem2), and three multi-step composite cements, two used following an etch-and-rinse (E&R) approach (RelyX ARC, Variolink II 'E&R') and one used following a self-etch (SE) approach (Variolink II 'SE') were investigated. The cement-tooth specimens were perpendicularly sectioned into micro-specimens (1.0 x 1.0 mm) in order to measure the pTBS. The data were statistically analyzed by ANOVA followed by Tukey HSD (P< 0.05). 24 additional specimens (four teeth per group) were prepared for interfacial characterization using SEM. Results: The tested SA cements bonded equally well to enamel and dentin. Etching of enamel improved their bonding effectiveness, which however remained inferior to that o f both E&R cements. SEM revealed a very similar interfacial ultrastructure at smear layer-covered enamel and dentin for the SA cements, exhibiting very superficial interaction at enamel and absence of a clearly detectable hybrid layer and resin tags in the dentin tubules. When the SA composite cements were applied to dentin free of a smear layer, regular and long resin tags were formed. [ABSTRACT FROM AUTHOR]

Introduction: Awake video-assisted thoracoscopic surgery (VATS) helps to avoid the adverse effects of general anaesthesia (GA) with single-lung ventilation. Its usage in anatomic and non-anatomic pulmonary resections has spread worldwide, and it is mostly performed under thoracic epidural analgesia (TEA). We herein report our surgical experience with awake VATS non-anatomical resections under the thoracic paravertebral block (TPB)., Patients and Methods: This retrospective, single-centred study reviewed patients undergoing awake VATS non-anatomical pulmonary resection under TPB, who voluntarily accepted awake VATS despite being suitable for GA and were found unsuitable for GA based on pre-operative assessment results. Demographic, pre-, per- and post-operative data were collected, analysed and compared with the literature data., Results: Twenty-four patients (16 patients with normal pre-operative assessment results and 8 patients having high risk for GA) were selected. Fourteen bullectomies for recurrent spontaneous pneumothorax and 10 wedge resections (nine for metastasectomy and one for lung biopsy) were performed. Global in-operating room time was 77 ± 31 min. The morbidity rate was 20.8% (n = 5), including prolonged air leak in three and pneumonia in two patients. The mean duration of the chest tube was 1.9 ± 1.5 days and mean duration of hospital stay was 3.5 ± 2.1 days. There was no in-hospital mortality. Our results were mostly similar to the literature data., Conclusion: Non-anatomical lung resections by VATS can be performed easily and safely under TPB in awake patients. Although the perioperative and post-operative outcomes are not superior to other anaesthesia approaches, preferring TPB may help to avoid the serious potential complications of TEA., (Copyright © 2024 Copyright: © 2024 Journal of Minimal Access Surgery.)

Background: This study aims to evaluate clinical and radiological characteristics of the patients with cough-induced rib fractures., Methods: Between January 2008 and December 2022, a total of 90 patients (35 males, 55 females; mean age: 58±20 years; range, 20 to 92 years) who had cough-induced rib fractures were retrospectively analyzed. Patients' characteristics, findings of physical and radiological examination, and patients' outcomes were recorded., Results: Of the patients, 64% were postmenopausal, 37% had metabolic disease of the bone, and 21% had chronic cough. Cough etiology was acute upper respiratory tract infection (32%), followed by chronic obstructive pulmonary disease. Thoracic computed tomography documented 154 fractures. Cough-induced rib fractures were mostly on the right side (58%). Multiple fractures were more commonly seen in older patients (p=0.007), in the presence of novel coronavirus disease-2019 (COVID-19) pneumonia (p=0.03), and metabolic disease of the bone (p=0.01). Mostly the sixth rib was affected (23%). Most fractures (81.3%) affected the fourth to ninth ribs. Most fractures developed on the anterolateral aspect of the rib (51%). The mean duration of hospital stay was 5.0±1.6 days. Morbidity developed in one patient (1.1%) (hemothorax). Mortality occurred in two patients (2.2%) due to COVID-19 pneumonia and acute myocardial infarction., Conclusion: Localized pain after cough should be investigated in terms of cough-induced rib fractures. Cough-induced rib fractures are mostly seen in the presence of acute upper respiratory tract infection, chronic obstructive pulmonary disease, and pneumonia. Postmenopausal women are more risky to develop cough-induced rib fractures. Multiple cough-induced rib fractures are common in the presence of metabolic disease of the bone, older age, COVID-19 pneumonia., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2024, Turkish Society of Cardiovascular Surgery.)

Purpose: To present the clinical experience in video-assisted thoracic surgery (VATS) of first rib resection for patients with neurogenic thoracic outlet syndrome (NTOS)., Methods: The files of 13 patients (10 males, 3 females) having unilateral NTOS undergoing first rib resection via VATS were retrospectively investigated. The symptoms, operative times, durations of chest tube and hospital stay, complications, and postoperative courses were analyzed. All patients underwent VATS using a camera port and 3-5 cm utility incision., Results: There was no morbidity. The average operation time was 81 ± 11 min (range 65-100 min). Chest tubes were removed in the first or second postoperative day (mean 1.23 ± 0.43 days). The mean postoperative length of hospital stay was 2.1 ± 0.9 days (range 1-3 days). The average duration of follow-up was 19 ± 13 months (range 2-38 months). Ten patients completed a follow-up during 6 months. One patient (10%) had minor residual symptoms, and the remaining patients (90%) were fully asymptomatic., Conclusion: The VATS approach in the resection of the first rib for thoracic outlet syndrome is a safe method. It should be performed with acceptable risks under experienced hands. The magnified view and optimal visualization from the scope are beneficial. Avoiding neurovascular bundle retraction may seem to decrease the postoperative pain.

Objectives: Hemoptysis is an alarming symptom. It may cause some severe life-threatening complications. Hypertrophic and fragile bronchial artery causes hemoptysis and occurs mostly in bronchiectasis, sarcoidosis, active or sequelae tuberculosis, aspergilloma, lung cancer or cystic fibrosis. Bronchial artery embolization is one of the angiographic methods used in diagnosis and treatment for years performed by radiologists. Hemoptysis is used mostly in patients with hemoptysis. Using this method, surgical management with high mortality and morbidity rates can be avoided or better conditions for surgery can be provided via stopping hemorrhage before surgery. We aim to share the experiences of our hospital about patients who underwent bronchial artery embolization and compare our results with the literature., Methods: Thirty-nine patients (29 male, 10 female) underwent angiography-aiming embolization. Pathologies were hemoptysis in 37 patients, Castleman disease in two patients. Embolization was performed in 33 patients; 31 for hemoptysis, two for Castleman disease. Bilateral embolization was performed in six patients., Results: Computed tomography (CT) was helpful in diagnosing the side of bleeding in 91.8% of the patients with hemoptysis. Bronchoscopy was diagnostic in 53% of patients. Polyvinyl alcohol (n=27) was mostly used for embolization. Hemoptysis recurred in six patients (19.3%). All were managed successfully, of four with re-embolization. One major complication, transient blindness, was observed., Conclusion: Bronchial artery embolization is minimally invasive, more tolerable compared to surgery can be managed with high success and lower complication rates, especially hemoptysis and in some other situations. It provides time for evaluating the underlying disease and delaying surgery for elective conditions. That is why this method has been used increasingly., Competing Interests: Conflict of Interest: None declared., (Copyright: © 2019 by The Medical Bulletin of Sisli Etfal Hospital.)

Objectives: Computed tomography-guided core needle biopsy has an important role in the accurate histopathological diagnosis of lung masses. The present study aims to share our results of computed tomography-guided percutaneous core needle biopsy of lung masses., Methods: A total of 117 patients had computed tomography-guided percutaneous core needle biopsy for lung masses between January 2017-September 2019 in our institution. In this study, these patients' post-procedural complications, diagnostic-yield-rates and radiological-histopathological correlations were evaluated retrospectively., Results: Complications occurred in 23 (20%) patients (20 (17%) of pneumothorax; 3 (3%) of hemorrhage). Chest-tube-drainage was needed in five (4%) of all patients. No significant difference was found between complication rates and patient gender/age, tumor volume/localization or needle-path-length (p>0.05). In 77 of the 85 (91%) primary-lung-cancer-cases radiological and pathological diagnostic results were correlated., Conclusion: Computed tomography-guided core needle biopsy has a high diagnostic yield rate with acceptable complication rates in the diagnosis of lung masses., Competing Interests: Conflict of Interest: None declared., (Copyright: © 2020 by The Medical Bulletin of Sisli Etfal Hospital.)

Background: This study aims to investigate the effects of blunt lung trauma performed in experimental rat model on lung tissue and blood as well as proinflammatory cytokines, oxidant-antioxidant enzymes and histopathological parameters after Ngamma-nitro-L-arginine methyl ester and N-iminoethyl-L-ornithine administration., Methods: The study included 50 adult male Wistar albino rats (weighing 350 to 400 g). Rats were randomly allocated into four groups. Except in the control, moderate-level pulmonary contusion was created in all other groups. Intraperitoneal saline solution was performed in groups 1 and 2, 25 mg.kg-1 Ngamma-nitro-L-arginine methyl ester in group 3, and 20 mg.kg-1 N-iminoethyl-L-ornithine in group 4. Blood and lung tissues were studied biochemically and histopathologically., Results: Best outcomes were recorded statistically significantly in groups with administration of Ngamma-nitro-L-arginine methyl ester and N-iminoethyl-L-ornithine when malondialdehyde response, mucous and histopathological values were examined. Significant improvement was detected in superoxide dismutase values in the group with administration of competitive nitric oxide synthase inhibitor Ngamma-nitro-L-arginine methyl ester. Nitric oxide values were substantially decreased in N-iminoethyl-L-ornithine group, while no significance was detected., Conclusion: Free oxygen radicals and lipid peroxidation played a role in pulmonary contusion after blunt lung trauma. According to biochemical and histopathological outcomes, effects of inflammation were decreased and protective effects were formed with administration of both Ngammanitro- L-arginine methyl ester and N-iminoethyl-L-ornithine., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2019, Turkish League Against Rheumatism.)
