A new technique for neonatal Jeune syndrome: External thoracic expansion.

Turk Gogus Kalp Damar Cerrahisi Derg 2021 Apr 26;29(2):279-282. Epub 2021 Apr 26.

Department of Thoracic Surgery, University of Medical Sciences, Şişli Etfal Training and Research Hospital, Istanbul, Turkey.

Jeune syndrome is a rare form of skeletal dysplasia characterized by a narrow, bell-shaped chest (thoracic cage), and typical phalangeal and pelvic bone deformities. Chest expansion is impaired by the short, horizontally positioned ribs, resulting in alveolar hypoventilation and eventually neonatal-infantile death in most cases. External distraction with sternoplasty is a new technique for the treatment of Jeune syndrome, which was firstly used by our team on a newborn by placing a sliding finger fixator which was designed for ulnar lengthening. We believe that this approach can be life-saving in neonates with improved and widespread usage.

Bronchial Artery Embolization, an Increasingly Used Method for Hemoptysis; Treatment and Avoidance.

Sisli Etfal Hastan Tip Bul 2020 25;54(3):313-319. Epub 2020 Aug 25.

Department of Radiology, Kocaeli University Faculty of Medicine, Kocaeli, Turkey.

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.

Diffusion MR: A New Diagnostic Tool for Elastofibroma Dorsi.

Sisli Etfal Hastan Tip Bul 2020 25;54(1):103-107. Epub 2020 Mar 25.

Department of Thoracic Surgery, Kocaeli University Faculty of Medicine, Kocaeli, Turkey.

Elastofibroma dorsi is a benign lesion commonly presents as a palpable enlarging mass at the inferior pole of the scapula. Clinical presentation and radiological characteristics are often enough to suggest an accurate diagnosis. Increased awareness of the characteristic appearance and location of these benign lesions will increase radiologic diagnosis and decrease the need for biopsy. Ten patients were admitted with a complaint of asymptomatic or painful subcutaneous masses localized at subscapulary region. Thorax computed tomography, magnetic resonance imaging (MRI) and a new feasible technique in differential diagnosis with malignancy and probable diagnosis of elastofibroma dorsi and diffusion-weighted MRI were used for diagnosis. Surgery was applied to all patients, frozen-section biopsies of the lesions at the preoperative period, and final pathologies were all benign. Totally resection of whole lesions as en-bloc excision without any rest was performed at all patients. Postoperative and follow-up periods were uneventful. Diffusion MRI can play an important role in the future and save the patients, especially medically poor ones, from the potential risks of surgery. Necessary further examinations for probable bilaterally lesions will save the patient from the risk of a second operation.

Computed Tomography-guided Transthoracic Core Needle Biopsy of Lung Masses: Technique, Complications and Diagnostic Yield Rate.

Sisli Etfal Hastan Tip Bul 2020 25;54(1):47-51. Epub 2020 Mar 25.

Department of Radiology, Istanbul Gaziosmanpasa Taksim Training and Research Hospital, Istanbul, Turkey.

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.

Effect of nitric oxide synthase inhibitors in acute lung injury due to blunt lung trauma in rats.

Turk Gogus Kalp Damar Cerrahisi Derg 2019 Jan 1;27(1):63-72. Epub 2019 Jan 1.

Department of Thoracic Surgery, Kocaeli University Faculty of Medicine, Kocaeli, Turkey.

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.

A rare malformation of urinary system: Right ectopic thoracic kidney.

Urol Ann 2017 Jul-Sep;9(3):299-300

Thoracic Surgery Clinic, Sisli Hamidiye Etfal Research and Training Hospital, University of Health Sciences, Sisli, Istanbul, Turkey.

An ectopic kidney is a common developmental anomaly of the urinary system. However, the thoracic kidney (TK) is the rarest state form of an aberrant kidney. The aim of this case report is defining the symptoms in TK diagnosis and constructing a treatment model will promote the best outcomes. These patients come to the physician with the various symptoms, and they could be diagnosed incidentally. In our case, we describe 40 years female patient with severe respiratory problems and upper back pain. In the pulmonary clinic, suspected mass was diagnosed with chest X-ray, and computerized tomography detected nontraumatic nonhernia associated, a truly ectopic TK. Moreover, the thoracic surgeon and urologist team decided to exploration and reconstructed the right ectopic kidney. The 1 month of the control of patient symptoms was disappeared. Overall, TK should be kept in mind in the differential diagnosis of thoracic tumors. Surgical exploration and reconstruction should be thought in patients who have severe respiratory symptoms.

The effect of surface sealants with different filler content on microleakage of Class V resin composite restorations.

Eur J Dent 2016 Apr-Jun;10(2):163-169

Department of Biometry and Genetics, Faculty of Agriculture, Suleyman Demirel University, Isparta, Turkiye.

Objective: Microleakage is still one of the most cited reasons for failure of resin composite restorations. Alternative methods to prevent microleakage have been investigated increasingly. The aim of this study is to evaluate the microleakage in Class V resin composite restorations with or without application of surface sealants with different filler content.

Materials And Methods: Ninety-six cavities were prepared on the buccal and lingual surfaces with the coronal margins located in enamel and the cervical margins located in dentin. The cavities restored with an adhesive system (Clearfil SE Bond, Kuraray, Tokyo, Japan) and resin composite (Clearfil Majesty ES-2, Kuraray, Tokyo, Japan). Teeth were stored in distilled water for 24 h and separated into four groups according to the surface sealants (Control, Fortify, Fortify Plus, and G-Coat Plus). The teeth were thermocycled (500 cycles, 5-55° C), immersed in basic fuchsine, sectioned, and analyzed for dye penetration using stereomicroscope. The data were submitted to statistical analysis by Kruskal-Wallis and Bonferroni-Dunn test.

Results: The results of the study indicated that there was minimum leakage at the enamel margins of all groups. Bonferroni-Dunn tests revealed that Fortify and GC-Coat groups showed significantly less leakage than the Control group and the Fortify Plus group at dentin margins in lingual surfaces (P < 0.05).

Conclusion: The all surface sealants used in this study eliminated microleakage at enamel margins. Moreover, unfilled or nanofilled surface sealants were the most effective in decreasing the degree of marginal microleakage at dentin margins. However, viscosity and penetrability of the sealants could be considered for sealing ability besides composition.
