[PMID: 38407400 DOI: 10.5830/cvja-2024-002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Accepted: 02/07/2024] [Indexed: 02/27/2024] Open
Abstract
Left ventricular free wall rupture (LVFWR) is a rare mechanical complication of acute myocardial infarction. The clinical course of LVFWR is very poor. Direct or patch closure of the rupture area and sutureless procedures constitute the treatment for LVFWR. We present the surgical treatment of a patient who developed LVFWR after high lateral myocardial infarction, and its successful outcome. Successful salvage of LVFWR remains relatively rare. Transthoracic echocardiography, myocardial contrast echocardiography and thoracic computed tomography are important diagnostic tools for LVFWR. These patients usually present with acute cardiac tamponade symptoms requiring immediate treatment.

Abstract
Objectives: Dysphagia is common in idiopathic Parkinson's disease (IPD) and is associated with impairments in both swallowing safety and swallowing efficiency. The goals of this study were to define post-swallow residue patterns in people with IPD and describe pathophysiological endoscopic findings affecting residue accumulation. Methods: This was a prospective single-blinded cross-sectional cohort study of patients with the diagnosis of IPD recruited from a Movement Disorder Clinic. Clinical variables included patient age, cognitive function, and measures of disease severity, and laryngoscopic examinations with a flexible endoscopic evaluation of swallowing (FEES) were completed for each patient. Visual Analysis of Swallowing Efficiency and Safety (VASES) was used to analyze FEES. Post-swallow residue outcomes and non-residue endoscopic outcomes including the Bowing index, Penetration Aspiration Scale (PAS) score, premature leakage, and build-up phenomenon were evaluated. Multiple regression models were used to evaluate factors affecting the residue at different anatomic levels. Results: Overall 53 patients completed the study. The multiple regression analyses showed a relation between (1) the presence of residue at the level of oropharynx and epiglottis with premature leakage, (2) the presence of residue at the level of the laryngeal vestibule and vocal folds with build-up phenomenon, and (3) the presence of residue at the level of the hypopharynx, laryngeal vestibule, and subglottis with airway invasion. Conclusion: Residue pattern during FEES is associated with specific swallow dysfunctions in IPD. Using residue localization and quantification may be a helpful tool in assessing the impact of targeted swallowing interventions in patients with IPD and dysphagia.

Long-term outcomes of facial nerve decompression by transmastoid versus middle cranial fossa approach for traumatic facial paralysis. Am J Otolaryngol 2023; 44:103983. [PMID: 37531887 DOI: 10.1016/j.amjoto.2023.103983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 07/02/2023] [Accepted: 07/04/2023] [Indexed: 08/04/2023]
Abstract
OBJECTIVES To evaluate and compare the long-term results of patients who underwent facial nerve decompression surgery with either transmastoid-supralabyrinthine (TMSL) or combined transmastoid- middle cranial fossa (MCF) approach for traumatic facial nerve paralysis. MATERIALS AND METHODS This is a single-center retrospective case-control study. The medical records of traumatic facial paralysis patients with House Brackmann (HB) Grade 6 who underwent facial nerve decompression surgery at via either TMSL or MCF approach between January 2011 and December 2017 were reviewed. The patients who had otic capsule involvement and total sensorineural hearing loss, therefore underwent translabyrinthine facial nerve decompression, and the patients follow-up period has not yet reached four years were excluded from the study. Postoperative HB score and hearing status were compared. RESULTS Eleven patients were operated with MCF approach (group 1), while 9 patients with TMSL approach (group 2). Average age of patients was 20.04 + 15.2 (range:4-47) years. Three (15 %) patients were female, while 17 (85 %) was male. Geniculate ganglion (90 %) was the most affected segment of the facial nerve. Facial nerve edema was observed in all cases, while intraneural hematoma were encountered in 4 (20 %) cases. Statistically significant improvement in median HB scores were reached in both groups, and no significant difference was observed in post-operative HB scores between both techniques. No significant difference in median AC 0,5-4 khZ and BC 0,5-3 kHz thresholds was observed between both techniques. CONCLUSION Even middle fossa approach is the best surgical technique to explore geniculate ganglion and labyrinthine segment of facial nerve, the functional results of transmastoid supralabrynthine approach, which is not needed craniotomy with low complication rate are as successful as middle fossa approach in selected patients.

[PMID: 37621278 PMCID: PMC10446264 DOI: 10.1002/lio2.1096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 05/17/2023] [Accepted: 06/04/2023] [Indexed: 08/26/2023] Open
Abstract
Objectives The study's primary objective was to compare the quality of life (QoL) and external auditory canal (EAC) hygiene among patients who underwent bony mastoid obliteration or meatoplasty after canal wall down (CWD) mastoidectomy. Methods A prospective, observational, controlled cohort study was conducted at our tertiary referral university hospital. Twenty-eight patients older than 16 years of age with chronic otitis media who underwent CWD mastoidectomy were included. Two cohorts were followed: CWD mastoidectomy followed by mastoid obliteration (Group 1, n = 14) and CWD mastoidectomy followed by meatoplasty (Group 2, n = 14). The main outcome measures of total COMBI score (postoperative 6-month QoL) and EAC hygiene were compared between the groups. Results The average age of the patients was 36.14 (12. 22) years; 15 (53.6%) were female and 13 (46.4%) were male. There were no differences in demographic variables, preoperative findings, or COMQ-12 (preoperative QoL) scores between groups. The average COMBI score of Group 1 (49.0 [8.66]) was not significantly different from Group 2 (46.79 [7.76]) (p = .482). Poor EAC hygiene was observed in eight (57.1%) patients in Group 2 and three (21.4%) patients in Group 1 (p = .06). In Group 1, no resorption of graft material was observed in 10 (71.4%) patients, minor resorption was observed in three (21.4%) patients, and significant resorption was observed in one (7.1%) patient. There were no significant differences in audiological findings between groups (p > .05). Conclusion There were no significant differences regarding short-term postoperative QoL, EAC hygiene, or hearing outcomes between patients who underwent bony mastoid obliteration or meatoplasty after CWD mastoidectomy. Level of Evidence 1b (individual prospective cohort study).

Presentation of dizziness in individuals with chronic otitis media: data from the multinational collaborative COMQ-12 study. Eur Arch Otorhinolaryngol 2022; 279:2857-2863. [PMID: 34291348 PMCID: PMC8294833 DOI: 10.1007/s00405-021-06993-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 07/13/2021] [Indexed: 11/16/2022]
Abstract
PURPOSE In chronic otitis media (COM), disease chronicity and severity of middle ear inflammation may influence the development of inner ear deficits, increasing the risk of vestibular impairment. This secondary analysis of the multinational collaborative Chronic Otitis Media Questionnaire-12 (COMQ-12) dataset sought to determine the prevalence of vestibular symptoms in patients with COM and identify associated disease-related characteristics. METHODS Adult patients with a diagnosis of COM in outpatient settings at nine otology referral centers across eight countries were included. We investigated the presence of vestibular symptoms (dizziness and/or disequilibrium) using participant responses to item 6 of a native version of the COMQ-12. Audiometric data and otoscopic assessment were also recorded. RESULTS This analysis included 477 participants suffering from COM, with 56.2% (n = 268) reporting at least mild inconvenience related to dizziness or disequilibrium. There was a significant association between air conduction thresholds in the worse hearing ear and presence of dizziness [adjusted odds ratio (AOR), 1.01; 95% CI 1.00-1.02; p = 0.0177]. Study participants in European countries (AOR 1.53; 95% CI 1.03-2.28; p = 0.0344) and Colombia (AOR 2.48; 95% CI 1.25-4.92; p = 0.0096) were more likely to report dizziness than participants in Asian countries. However, ear discharge and cholesteatoma showed no association with dizziness in the adjusted analyses. CONCLUSION Vestibular symptoms contribute to burden of disease in patients with COM and associates with hearing disability in the worse hearing ear. Geographical variation in presentation of dizziness may reflect financial barriers to treatment or cultural differences in how patients reflect on their health state.

Evaluation of the factors affecting the necessity for revision surgery in choanal atresia. Int J Pediatr Otorhinolaryngol 2021; 151:110929. [PMID: 34600192 DOI: 10.1016/j.ijporl.2021.110929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 07/08/2021] [Accepted: 09/18/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE This study aims to compare the effects of different surgical techniques for congenital choanal atresia (CCA), and particular emphasis is given to the analysis of the factors affecting the surgical outcome. The necessity for revision surgery and surgical outcomes were retrospectively investigated in patients undergoing revision surgery according to a recently proposed classification system. MATERIAL AND METHOD A retrospective study was conducted on patients operated for CCA between January 2007 and December 2018 at a university hospital. Data in the medical records, including patient age when the initial surgery was performed, gender, additional anomalies and medical conditions, the duration of gestation, side and type of atresia, type of surgery and need for revision surgery were reviewed. RESULTS Forty-five patients treated for CCA in our university hospital were screened. The mean follow-up duration was 82.16 months. Revision surgery was required in 9 of 26 cases, which are included in the study (34.6%). Fourteen patients presented with bilateral CCA, while 12 were unilateral cases. Sixteen patients (61.5%) had comorbid medical conditions. While the removal of vomer and mucoperiosteal flap use affects successful surgical repair, no differences were observed in choanal atresia type, laterality, use of stent and the presence of additional medical conditions. CONCLUSION The most important factors affecting surgical success for CCA are the removal of the vomer and closure of all bare bone tissues using a mucoperiosteal flap. Use of stents provides no additional benefit, apart from preventing synechiae formation.

Abstract
Background:Carpal tunnel syndrome(CTS) is the most common form of entrapment neuropathies,caused by compression of the median nerve in the carpal tunnel at the wrist. But there is no gold standard technique for diagnosing CTS. Electrodiagnostic studies (EDS) are generally used but have some limitations. Recent years, magnetic resonance imaging(MRI) and ultrasonography(US) have facilitated the diagnosis of CTS. The median nerve cross section area(CSA) measured by US or MRI has been found to be associated with CTS[1]][2].CTS is usually idiopatic but it can be seen more in some disease. Psoriatic arthritis(PsA) occurs in up to 30% of people with psoriasis and can have serious debilitating effects on the peripheral joints, spine, tendon insertions, and fingers[3]. Because of arthritis, steroid use and flexor tenosynovitis play an important role in the pathogenesis of CTS, we think that CTS can be seen more in PsA patients.Objectives:We aimed to investigate the CTS in PsA patients with EDS, US and MRI than compare them with healthy controls.Methods:68 people, including 39 PsA (according to CASPAR criteria) and 28 healthy volunteers were included in study within 1 year. EDS, US and MRI were performed within maximum 2 weeks, and measurements were made by different doctors who were blind to other measurments. EDS was started with median and ulnar nerve motor conduction study than continued with sensory conduction studies. CTS diagnose was made according to the routine laboratory standards. The CSA measurement was made from the inner border of the hyperechoic ring around median nerve by using continuous tracing method at psiform bone level. US examinations were performed with a high frequency linear transducer (4-14 MHz), MRI examinations were performed on a 3-T imaging system. The statistical analyses were performed with Statistical Package for the Social Science Program Version 22. Descriptive statistics, T tests, chi-square test, Pearson correlation test were used.Results:No statifically significant difference was found between the groups for demographic characteristics. 12 (30.76%) of 39 PsA patients had CTS, whereas CTS was not detected in the control group(p= 0.001). US and MRI show larger CSA in PsA patients compared to the healthy control group(9,49 ± 3,00 mm2 vs 8,30 ±1,73mm2 p=0,005, 11,24 ± 3,41mm2 vs 9,35 ± 1,81mm2 p<0,001); in patients with CTS compared to others(11,63 mm2 ± 3,25 vs 8,60 ± 2,26mm2 p=0,002, 13,37 ± 3,37 mm2 vs 9,90 ± 1,58mm2 p<0,001) and in PsA patients which have CTS compared to PsA patients with normal EDS(11,63 ± 3,25 mm2 vs 8,87 ± 2,64 mm2 p=0,001, 13,37 ± 3,37 mm2 vs 10,52 ±3,15 mm2 p=0,003). When the CSA compared PsA patients which have normal EDS and healthy volunteers; US (8,87 ± 2,64 vs 8,30 ±1,73 p=0,180) and MRI (10,52 ±3,15 vs 9,35 ± 1,81 p=0,026) show larger CSA in PsA patients. But differance isn’t statistically significant for US measurments. The Pearson correlation coefficient between MRI and US measurements of the CSA was 0.85 (P<0,001).Conclusion:CTS is more common in patients with PsA. The relationship between CTS diagnosed by EDS and CSA measured by US or MRI was observed in both PsA patients and all participants. Diagnosis can be supported by US or MRI in patients who can not undergo EDS or who do not accept EDS. For PsA patients, cut off values obtained from normal people should not be used. The limitations of our study were that our CTS population was small and most of them was mild. We think that this study will be the precursor of CTS studies in PsA patients.References:[1]M. S.

Abstract
OBJECTIVE To present 18-month clinical results for internal compression therapy (ICT) applied percutaneously and as a novel method in the treatment of primary deep venous insufficiency. MATERIAL AND METHOD Thirty patients diagnosed with isolated primary femoral vein (FV) insufficiency between October 2017 and February 2018 were included in the study. Pre-procedural femoral vein diameters and reflux durations were measured. CEAP classification and Venous Clinical Severity Score (VCSS) were recorded. Pre-procedural CEAP classifications were CEAP 4 in nine patients and CEAP 3 in 21. Quality of life assessments were carried out using a Chronic Venous Insufficiency Questionnaire (CIVIQ-2). FV diameters were then reduced, and valve coaptation was established with the percutaneous application of hyaluronic acid and cyanoacrylate injected adjacent to a valve with non coapting leaflets. Venous diameters and reflux duration were again measured immediately after the procedure. Patients were followed-up at months 1, 6, and 18, at which times all parameters were re-evaluated. RESULTS Eighteen of the 30 patients were women, and 12 were men. The mean duration of the procedure was 22.7 ± 2.9 (20-30) min. Patients' FV diameters were 12.8 (11-14.7) mm before the procedure, 9.9 (9-11.5) mm immediately after, and also 9.9 (9-11.2) mm after 1.5 years (p < 0.001). Pre-procedural reflux duration ranged between 2 and 6 (median: 3) sec, and no reflux was observed in any patient immediately or one month after the procedure (p < 0.001). At 18-month follow-up, reflux lasting only 1 sec was determined in two patients. VCSS scores were 11 (10-12) pre-procedurally and 6 (4-9) at 18 months (p < 0.001). Venous Quality of Life scores were 32 (30-36) before the procedure and 18 (14-24) at 18 months (p < 0.001). CONCLUSION Preliminary investigation of the injection of cyanoacrylate and hyaluronic acid around one valve in an incompetent FV can result in improved hemodynamics, CEAP, VCSS and patient QOL at 18 months, without complications.

Abstract
OBJECTIVES Mutations of the SLC26A4 gene causing enlarged vestibular aqueduct (EVA) syndrome have not yet been fully elucidated. The study aimed to investigate SLC26A4 mutations in patients with EVA syndrome in the Turkish population. Identifying these mutations may play an essential role in determining the prognosis, follow-up, and management options of these patients. METHODS Whole exome sequencing and/or Sanger sequencing of SLC26A4 in 22 patients with sensorineural hearing loss associated with isolated EVA without inner ear anomalies, and 22 controls were performed. RESULTS Twenty-two patients and 22 control subjects were included in the study. The onset of hearing loss was pre-lingual in 15 patients, and post-lingual in 7. The mean (standard deviation) vestibular aqueduct width of the patients was 3.23 mm (1.28). Twenty SLC26A4 variants, 15 of them unique, were identified in 22 patients. Among them, seven variants were heterozygous, and 13 were homozygous. The variants p.E37X (c.109G > T), p.Y27H (c.79T > C), p.C706Y (c.2117G > A) have not been previously reported. CONCLUSION The detection of rare and previously unreported mutations in our study showed that studies with a larger number of patients with EVA might reveal more role of the SLC26A4 gene. Besides, to understand the etiopathogenesis of the disease, other related genes also should be investigated.

Abstract
OBJECTIVES Pre-operative airway evaluation is essential to decrease the proportion of possible mortality and morbidity due to difficult airway (DA). The study aimed to evaluate the accuracy of pre-operative ultrasonographic airway assessment (UAA) and indirect laryngoscopy (IL) in predicting DA. STUDY DESIGN Prospective obsevational study. METHODS Preoperative clinical examination (body mass index [BMI], mallampati classification [MP], thyromental distance, sternomental distance, neck circumference), UAA (epiglottis-skin distance [ESD], hyoid bone-skin distance [HSD], the thickness of tongue root [ToTR], anterior commissure-skin distance [ACSD]) and IL with the rigid 70-degree laryngoscope were performed to predict DA (Cormack-Lehane grade 3 and 4). The sensitivity, specificity, positive predictive value (PP), and negative predictive values of the parameters were assessed. RESULTS Twenty-two of 140 (15.7%) patients were diagnosed with DA. The cut-off points of ESD, HSD, ToTR, ACSD, and BMI were 2.09 cm, 0.835 cm, 4.05 cm, 0.545 cm, and 27.10, respectively. AUC values were 0.874, 0.885, 0.871, 0.658, and 0.751 in the same order. AUC values for IL and MP were 0.773 and 0.925, respectively. MP and HSD had the best sensitivity (91%), IL grading had the best specificity (100%), and PP (100%) value among all measurements. The best-balanced sensitivity (91%), specificity (97%), and PP (88%) values were obtained by combining the IL with MP and ESD or with MP and HSD. CONCLUSIONS Ultrasonographic measurements and IL were found significantly correlated to predict DA. Combined parameters, the IL with MP and ESD or with MP and HSD, are the best parameters in predicting the DA. LEVEL OF EVIDENCE 4 Laryngoscope, 131:E555-E560, 2021.

The changes of endotracheal tube intracuff pressures after ear and head and neck surgery-related positions: a prospective observational study. Braz J Otorhinolaryngol 2020; 88:46-52. [PMID: 32571751 PMCID: PMC9422739 DOI: 10.1016/j.bjorl.2020.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2020] [Revised: 02/19/2020] [Accepted: 05/03/2020] [Indexed: 11/02/2022] Open
Abstract
INTRODUCTION The cuff of an endotracheal tube seals the airway to facilitate positive-pressure ventilation and reduce subglottic secretion aspiration. However, an increase or decrease in endotracheal tube intracuff pressure can lead to many morbidities. OBJECTIVE The main purpose of this study is to investigate the effect of different head and neck positions on endotracheal tube intracuff pressure during ear and head and neck surgeries. METHODS A total of 90 patients undergoing elective right ear (Group 1: n=30), left ear (Group 2: n=30) or head and neck (Group 3: n=30) surgery were involved in the study. A standardized general anesthetic was given and cuffed endotracheal tubes by the assistance of video laryngoscope were placed in all patients. The pilot balloon of each endotracheal tube was connected to the pressure transducer and standard invasive pressure monitoring was set to measure intracuff pressure values continuously. The first intracuff pressure value was adjusted to 18.4mmHg (25cm H2O) at supine and neutral neck position. The patients then were given appropriate head and neck positions before related-surgery started. These positions were left rotation, right rotation and extension by under-shoulder pillow with left/right rotation for Groups 1, 2 and 3, respectively. The intracuff pressures were measured and noted after each position, at 15th, 30th, 60th, 90th minutes and before the extubation. If intracuff pressure deviated from the targeted value of 20-30cm H2O at anytime, it was set to 25cm H2O again. RESULTS The intracuff pressure values were increased from 25 to 26.73 (25-28.61) cm H2O after left neck rotation (p=0.009) and from 25 to 27.20 (25.52-28.67) cm H2O after right neck rotation (p=0.012) in Groups 1 and 2, respectively. In Group 3, intracuff pressure values at the neutral position, after extension by under-shoulder pillow and left or right rotation were 25, 29.41 (27.02-36.94) and 34.55 (28.43-37.31) cm H2O, respectively. There were significant differences between the neutral position and extension by under-shoulder pillow (p<0.001), and also between neutral position and rotation after extension (p<0.001). However, there was no statistically significant increase of intracuff pressure between extension by under-shoulder pillow and neck rotation after extension positions (p=0.033). CONCLUSION Accessing the continuous intracuff pressure value measurements before and during ear and head and neck surgeries is beneficial to avoid possible adverse effects/complications of surgical position-related pressure changes.

A macroscopic comparison study on main branches of arteria brachialis and arteria subscapularis in Southern Karaman and Hasak sheep breeds. Folia Morphol (Warsz) 2020; 80:297-301. [PMID: 32488858 DOI: 10.5603/fm.a2020.0058] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 03/31/2020] [Accepted: 05/10/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND The Southern Karaman sheep, which is very fertile in terms of meat and milk production and is often preferred in livestock raising, is known as a domestic sheep breed. The Hasak sheep is a breed formed by the triple crossbreeding of the German Black-headed, Hampshire and Akkaraman breeds. Arterial feeding of the forelimb is provided by arteria axillaris, a continuation of arteria subclavia. In this study, it was aimed to examine the forelimb arteries in Southern Karaman and Hasak sheep breeds. MATERIALS AND METHODS Totally, 8 Southern Karaman and 8 Hasak sheep were obtained from Konya Bahri Dagdas International Agricultural Institute. The sheep were anesthetised with xylazine and ketamine and extravasated by cutting the arteria carotis communis in the neck area of the sheep. The forelimbs of the sheep separated from the body were fixed in 10% formaldehyde solution and then dissections were made and the course and branching of the arteries were examined. RESULTS It was determined that the arteria brachialis was divided into two main branches as distal arteria brachialis and proximal arteria subscapularis at the articulatio humeri level of the arteria axillary. Arteria mediana, which is a continuation of arteria brachialis, was also examined in different parts of antebrachium and ended by splitting into branches. CONCLUSIONS According to the findings of the Southern Karaman and Hasak sheep breeds, it was determined that the forelimb arteries had some anatomical differences but were similar in structure to many sheep breeds.

Abstract
Objective The aim of this study was to translate the Chronic Otitis Media Benefit Inventory (COMBI) into Turkish and evaluate the questionnaire's reliability in assessing benefit outcomes in patients after ear surgery. Methods A total of 30 patients with chronic otitis media who underwent ear surgery were asked to fill out the translated Turkish version of the COMBI questionnaire six months after their surgery twice, 10 days apart. The patients were divided into two groups in two different ways based on surgical and audiological outcomes. These were surgical success (SS), surgical failure (SF), audiological success (AS), audiological failure (AF) groups. Student's -t test was performed to show the differences in the COMBI scores of the groups. Cronbach's alpha value was calculated to test internal consistency, Pearson's correlation coefficient was measured to demonstrate test-retest reliability and factor analysis was run. Results The average score of the SS group was 51.08 and significantly higher than the score of the SF group (42.40) (p=0.012). There was, however, no statistically significant difference between the average scores of the AS and the AF groups (p=0.330). A Cronbach's alpha value of 0.862 was found. Pearson's r value was calculated 0.810. Factor analysis showed that a three-factor solution explained the 70.2% of the variance. Conclusion The Turkish version of the COMBI is a valid test with high test-retest reliability. It should be used with objective assessment tools for better understanding how patients benefit from the surgery.

Abstract
BACKGROUND The interdigital glands of sheep perform various functions including those pertaining to sexual behaviours. Morphological and histological structure of the gland demonstrates differences among species. The aim of this study is to examine the morphological and histological structure of Hasak and Hasmer sheep's interdigital glands and to determine the differences with other sheep breeds. MATERIALS AND METHODS For this research, we selected 7 Hasak and 7 Hasmer female sheep. After scarification, the feet were obtained and used for anatomical and histological examinations. For the histological examination, the interdigital gland tissues were stained with Crossman modified triple, periodic acid Schiff (PAS) and Alcian blue (AB) staining. RESULTS The morphometric analysis results, mean values of weight, body length, body diameter, flexura, ductus length, ductus diameter, were observed as 0.80 mm, 14.61 mm, 5.98 mm, 5.62 mm, 26.58 mm, and 3.25 mm, respectively in Hasak and 0.8 mm, 15.46 mm, 6.37 mm, 5.70 mm, 24.52 mm, and 3.52 mm in Hasmer sheep. The histochemical staining revealed that the apocrine secretion of this gland was PAS positive and AB negative. CONCLUSIONS The weight, body length, body diameter, flexura, ductus length and ductus diameter in the forefoot's interdigital glands of both Hasak and Hasmer sheep were higher in a statistically significant manner than those of the hindfeet's glands.

Abstract
Non-sebaceous lymphadenoma is a sporadic benign tumor of salivary glands. Histopathologic and immunohistochemical properties, diagnostic criteria, and theories for the histologic origin of the disease have been defined and well-discussed in the literature. However, none of the cases showed malignant transformation to date. We reported a case of 54 years old female patient with a right preauricular mass. Magnetic resonance imaging demonstrated a 2 cm, well-defined contrast-enhanced mass in the right parotid gland. Fine needle aspiration cytology was undiagnostic but suspicious for malignancy. Total parotidectomy with facial nerve preservation was done. In the histopathological examination, non-sebaceous lymphadenoma regions and malignant cells with abundant cytoplasm, large vesicular nuclei, and prominent nucleoli, which occupied approximately 70% of the mass, were seen. The diagnosis was undifferentiated carcinoma arisen from non-sebaceous lymphadenoma. Adjuvant radiotherapy was given. No recurrence was detected during ten months of follow-up. This case is the first case of a malignancy developed from non-sebaceous lymphadenoma.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence and risk factors of carotid artery stenosis (CAS) using carotid duplex ultrasound in patients undergoing coronary artery bypass grafting (CABG). METHODS This retrospective study was conducted between January 2017 and January 2018 and included 166 consecutive patients [130 males (78.31%), 36 females (21.69%); mean age: 64.25±9.78 years] who underwent elective and isolated CABG. Patients who had significant CAS (≥50% stenosis) were compared with patients who had non-significant CAS (<50% stenosis). Logistic regression analysis was applied across the selected parameters to identify risk factors for significant CAS. RESULTS Of all patients, 36 (21.68%) had CAS ≥50% and 8 (4.81%) had unilateral carotid stenosis ≥70%. Carotid endarterectomy/CABG was performed simultaneously in five (3.01%) patients. None of these patients had cardiac and neurological problems during the postoperative period. The overall incidence of cerebrovascular accident (CVA) after CABG was 1.20% (n=2). Age (P=0.011) and history of CVA (P=0.035) were significantly higher in the CAS ≥50 group than in the CAS <50 group. Significant CAS was identified as a risk factor for postoperative CVA (P=0.013). CONCLUSION Age and history of CVA were identified as risk factors for significant CAS. Furthermore, significant CAS was identified as a risk factor for postoperative CVA. For this reason, carotid screening is recommended for patients undergoing CABG even in the absence of associated risk factors.

Abstract
INTRODUCTION Postoperative bleeding requires blood transfusion and surgical re-exploration that can affect the short- and long-term postoperative outcomes. Interventions that can be used in the postoperative period to reduce blood loss should be developed. Continuous postoperative pericardial flushing (CPPF) with an irrigation solution may reduce blood loss by preventing the accumulation of clots. This study examined the feasibility and acceptability of CPPF for reducing bleeding after coronary artery bypass surgery. METHODS This pilot study adopted a prospective and group comparison design. Between January and April 2018, 42 patients who underwent isolated coronary artery bypass surgery received CPPF from sternal closure up to 8 h postoperative. The mean actual blood loss in the CPPF group was compared to the mean of retrospectively group (n = 58). In the CPPF group, an extra infusion catheter was inserted through one of the tube incision holes and an irrigation solution (0.9% NaCl at 38 °C) was delivered to the pericardial cavity by using a volumetric pump. Safety aspects, feasibility issues, and complications were documented. The primary outcome was blood loss, and it was assessed 18 h after the surgery. RESULTS CPPF was successfully completed in 40 patients (95.24%). Method-related complications were not observed. Feasibility was good in this experimental setting. Blood loss was lower in the CPPF group (257.24 mL) than non-CPPF group (p < 0.001). CONCLUSIONS CPPF after coronary artery bypass grafting surgery is safe, effective, feasible, and acceptable. However, standardized randomized clinical trials are necessary to draw definitive conclusions.

Abstract
Objective The aim of this study was to translate the Chronic Otitis Media Questionnaire-12 (COMQ-12) into Turkish, evaluate the internal consistency of the test and test-retest reliability, and validate the adaptation for further use in Turkish studies. Methods A total of 50 healthy subjects and 50 patients with chronic otitis media (COM) have completed a translated Turkish version of the COMQ-12. Healthy subjects were asked to complete the test twice. A statistical analysis was performed to evaluate the validity and test-retest reliability of the questionnaire. Patients were divided into three groups. Group 1 were patients with COM; Group 2 represented the first test of the control group; and Group 3 represented the second test of the control group. Cronbach's test was performed to test internal consistency, and Spearman's test was performed to evaluate test-retest validity. Results The average score was 30.64 for Group 1, 3.60 for Group 2, and 3.66 for Group 3. The COMQ-12 score of the patient group was significantly higher than the score of the control group (p<0.001). The area under the receiver operating characteristics curve value was calculated as 0.992, which showed a strong diagnostic accuracy, and the cut-off point was defined as 9. A Cronbach's alpha value of 0.810 was found. Spearman's rank correlation coefficient value (Spearman's rho) was calculated as 0.920. Conclusion The Turkish adaptation of the COMQ-12 is a consistent and valid test with high sensitivity and specificity that can be used in Turkish for further studies instead of the original questionnaire.

Abstract
This article reports on a U.K. workshop on social media research ethics held in May 2018. There were 10 expert speakers and an audience of researchers, research ethics committee members, and research institution representatives. Participants reviewed the current state of social media ethics, discussing well-rehearsed questions such as what needs consent in social media research, and how the public/private divide differs between virtual and real-life environments. The lack of answers to such questions was noted, along with the difficulties posed for ethical governance structures in general and the work of research ethics committees in particular. Discussions of these issues enabled the creation of two recommendations. The first is for research ethics committees and journal editors to add the category of ‘data subject research’ to the existing categories of ‘text research’ and ‘human subject research’. This would reflect the fact that social media research does not fall into either of the existing categories and so needs a category of its own. The second is that ethical issues should be considered at all stages of social media research, up to and including aftercare. This acknowledges that social media research throws up a large number of ethical issues throughout the process which, under current arrangements for ethical research governance, risks remaining unaddressed.

Abstract
OBJECTIVE To date, there is no consensus on the selection of type and size of prosthetic valve for aortic valve replacement (AVR). The aim of this study was to compare anatomical and functional changes occurring in the left ventricle after AVR with different sizes of mechanical valves. METHODS A total of 92 patients with serious aortic valve stenosis, who underwent AVR between March 2001 and June 2008 using mechanical valves of different sizes, were retrospectively analysed. The sizes of the mechanical valves were 19, 21, 23 and 25 mm. All patients were assessed preoperatively, and at six months and in the first, third and fifth years postoperatively. The left ventricle was assessed with electrocardiography, echocardiography and telecardiography and compared in the four patient groups, constituted according to the mechanical valve size used. RESULTS In all groups, left ventricular mass and mass index, transvalvular aortic gradient, thicknesses of the interventricular septum and posterior wall, and left ventricular endsystolic and end-diastolic diameters had decreased significantly post surgery. Left ventricular ejection fraction and exercise capacity had increased significantly (p < 0.001). The most noteworthy anatomical and functional improvements were seen in patients who had received 23- and 25-mm mechanical valves. CONCLUSION Mechanical valve replacement should not be performed with small size valves because of the higher residual gradient.

Abstract
Background Nesfatin-1 is involved in cardiovascular regulation, stress-related responses. The objective of this study is to investigate the impact of volatile anesthetics on Nesfatin-1 levels. Method Fourty-two patients aged 30–65 years with the American Society Anesthesiology (ASA) Class I-II who were scheduled for laparoscopic cholecystectomy were included in the study Patients were randomized into two group; desflurane administered group (Group I, n = 21) and sevoflurane administered group (Group II, n = 21). For anesthesia maintenance, the patients received 6% desflurane or 2% sevoflurane in 40% O2 and 60% air. The patient’s heart rate (HR), mean, systolic and diastolic arterial pressures (MAP, SAP, DAP), peripheral O2 saturation (SpO2) were monitored and recorded before induction, after induction, after intubation, and during extubation. Blood samples were collected before induction (T1), and after extubation when aldrete score was 10 (T2). Results Demographic data were similar between the groups. The preoperative levels of nesfatin were similar in the two groups (p = 0.715). In desflurane group, post-operative nesfatin levels were similar compared to preoperative levels (p = 0.073). In sevoflurane group, post-operative nesfatin levels were similar (p = 0.131). The nesfatin levels (postoperative vs preoperative) were similar between the groups (p = 0.900). Conclusion In conclusion, this study results suggest that nesfatin-1 levels are not affected by the use of sevoflurane or desflurane in patients undergoing laparoscopic cholecystectomy.

Abstract
Objective: This prospective study aimed to investigate the effects of the selective angiotensin receptor antagonist, telmisartan, on microalbuminuria after coronary artery bypass surgery in patients with diabetes mellitus. Methods: Patients were divided into two groups with block randomisation, using the sealed envelope technique: group T (telmisartan group) consisted of patients who received the angiotensin receptor blocking agent telmisartan 80 mg daily for at least six months in the pre-operative period; group N-T (non-telmisartan group) consisted of patients who received no telmisartan treatment. Clinical and demographic characteristics, operative and postoperative features, microalbuminuria and high-sensitivity C-reactive protein levels were compared. Results: Forty patients met the eligibility criteria for the study. The groups did not differ with regard to clinical and demographic characteristics, and operative and postoperative features. Microalbuminuria levels between the groups differed significantly in the pre-operative period, first hour postoperatively and fifth day postoperatively. C-reactive protein levels between the groups differed significantly on the fifth day postoperatively. Conclusion: Telmisartan was useful for decreasing systemic inflammation and levels of urinary albumin excretion in patients who had type 2 diabetes mellitus and had undergone coronary artery bypass surgery.

Abstract
INTRODUCTION Anthrax is a bacterial disease caused by the aerobic sporeforming bacterium Bacillus anthracis. It has been suggested that oxidative stress plays an important role in the pathogenesis of B. anthracis. The aim of this study was to investigate serum paraoxonase 1 (PON1) activity, catalase activity, malondialdehyde (MDA) levels, and superoxide dismutase (SOD) levels in patients with cutaneous anthrax. MATERIALS AND METHODS Fifteen patients with cutaneous anthrax and 15 healthy controls were enrolled in this study. The serum MDA levels, SOD levels, paraoxonase, arylesterase, and catalase activities were measured using a spectrophotometer. RESULTS The serum SOD levels, paraoxonase, arylesterase, and catalase activities were significantly lower in patients with cutaneous anthrax than in controls (for all, p < 0.001), whereas MDA levels were significantly higher ( p < 0.001). No significant correlation was found between serum paraoxonase activity, arylesterase activity, SOD levels, and MDA levels (all, p > 0.05) in patients with cutaneous anthrax. CONCLUSIONS The current study was the first to show decreased antioxidant levels and increased oxidant levels in patients with cutaneous anthrax. Therefore, decreased PON1 activity may play a role in the pathogenesis of cutaneous anthrax.

Abstract
Objective This report aims to present the early results of a retrospective study of the use of N-butyl cyanoacrylate (VariClose®)-based non-tumescent endovenous ablation for the treatment of patients with varicose veins. Method One hundred and eighty patients with varicose veins due to incompetent saphenous veins were treated with the VariClose® endovenous ablation method between May 2014 and November 2014. The patient sample consisted of 86 men and 94 women, with a mean age of 47.7 ± 11.7 years. The patients had a great saphenous vein diameter greater than 5.5 mm and a small saphenous vein diameter greater than 4 mm in conjunction with reflux for more than 0.5 s. Patients with varicose veins were evaluated with venous duplex examination, Clinical, Etiological, Anatomical and Pathophysiological classification (CEAP), and their Venous Clinical Severity Scores were recorded. Results The median CEAP score of patients was three, and the saphenous vein diameters were between 5.5 and 14 mm (mean of 7.7 ± 2.1 mm). A percutaneous entry was made under local anesthesia to the great saphenous vein in 169 patients and to the small saphenous vein in 11 patients. Duplex examination immediately after the procedure showed closure of the treated vein in 100% of the treated segment. No complications were observed. The mean follow-up time was 5.5 months (ranging from three to seven months). Recanalization was not observed in any of the patients during follow-up. The average Venous Clinical Severity Scores was 10.2 before the procedure and decreased to 3.9 after three months (p < 0.001). Conclusion The application of N-butyl cyanoacrylate (VariClose®) is an effective method for treating varicose veins; it yielded a high endovenous closure rate, with no need for tumescent anesthesia. However, long-term results are currently unknown.

Abstract
Iron overload is known to affect erythrocyte membrane properties and erythrocyte shape. We hypothesized that iron overload which directly affects the erythrocyte morphology may also interfere with erythrocyte deformability (ED). Exenatide, a glucagon like peptide -1 (GLP-1) analogue used in the treatment of diabetes, is known to have beneficial pleiotropic effects on endothelial function and blood flow which are different from its glucose-lowering effects. In our study we aimed to test the effect of iron overload on ED in a rat model (1) and to evaluate the effect of exenatide on ED in the same model (2). For this purpose, the animals were randomly divided into three groups, each containing 6 rats. Rats in the control group (Group C) were given intraperitoneal injections of saline as placebo. The second group (Group Fe) was given intraperitoneal iron dextran (60 mg/kg/day) five days a week for 4 weeks to develop iron overload. The third group (Group Fe +E) received subcutaneous injections of 10 mcg exenatide (Byetta® Lilly Pharma) in two divided doses for 4 weeks in addition to iron dextran. We observed that ED index was significantly higher in Group Fe when compared to Group C and Group Fe+E (p Keywords: erythrocyte deformability, iron, exenatide.

Abstract
BACKGROUND Ischemia reperfusion injury (I/R) in lower extremity is a frequent and important clinical phenomenon. Protective effect of alprostadil on local and distant organ injury due to I/R has been well-documented but its effect on erythrocyte deformability needs further investigation. Our aim was to investigate the effect of alprostadil on erythrocyte deformability in infrarenal aorta of rats undergoing I/R. MATERIALS AND METHODS Our study was conducted with 18 Wistar albino rats. Rats were divided into 3 groups; randomized control group (group C; n=6), I/R group without alprostadil (group I/R; n=6) and I/R group with alprostadil 20 mcg.kg(-1), intraperitoneal (group I/R-A; n=6). Packs of erythrocytes were prepared from heparinized blood samples and deformability measurements were done. RESULTS Comparisons of the control and I/R-A groups revealed similar results (p=0.240). The values of the IR group were significantly higher than those of the control and IR-A groups (p=0.009, p=0.026, respectively). CONCLUSION In our study, we detected unfavourable effects of I/R on erythrocyte deformability, which may lead to disturbance in blood flow and hence tissue perfusion in infrarenal rat aorta. We also found that alprostadil had beneficial effects by reversing undesirable effects of I/R (Fig. 1, Ref. 22).

Abstract
OBJECTIVES The purpose of this study was to assess the severity of pulmonary embolism in the emergency department using vital signs and age-based vital parameters and compare these parameters with pulmonary embolism severity index (PESI) score. METHODS Between January 2011 and October 2014, there were 284 patients diagnosed with pulmonary embolism in the Emergency Unit of Selcuk University Hospital. Patient records were reviewed retrospectively. The PESI scores were calculated, and patients were divided into high- and low-risk groups. Shock index (SI), age-based shock index (SIA), maximum heart rate (MHR), minpulse (MP) and pulse maximum index (PMI) were calculated. The association of these parameters with PESI was evaluated. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the association of risk and mortality with age-based markers. RESULTS There were 75 men (43%) in the 173 patients included in the study. The PESI classification showed 54 patients in the low-risk group and 119 patients in the high-risk group. Mortality was higher in the PESI high-risk group, and no deaths occurred in the low-risk group. Comparison of the age-based markers and PESI for patients who died or survived showed that AUC for PESI was 0.807, AUC for SI was 0.824 and AUC for SIA was 0.825. CONCLUSIONS The SIA risk classification was more efficient than SI in pulmonary embolism patients who presented to the emergency unit. The SIA was more accurate than SI or PESI in predicting mortality.

Abstract
Background Anticoagulant treatment is recently being replaced by more aggressive endovascular modalities in the management of acute deep vein thrombosis (DVT). These techniques have been promoted to improve thrombus removal, prolong venous patency, prevent venous insufficiency, and reduce post thrombotic syndrome. The aim of the present study is to overview the short-term results of percutaneous mechanical thrombectomy (PMT) for acute DVT. Methods This retrospective study is based on data from 21 acute DVT patients treated with PMT in the cardiovascular surgery department of a tertiary care center. The average age of patients was 48.76 (range: 27-69). Retrievable inferior vena cava (IVC) filters were administered via right subclavian vein or contralateral femoral vein and withdrawn after PMT procedure. Low-molecular-weight heparin (LMWH) was used for anticoagulation in the first 10 days postoperatively. Results Venous patency was restored in 20/21 patients (95%) at first month, and in 18/21 patients (85%) at sixth month. Valvular competency was preserved in 16 patients (76%). Balloon angioplasty with or without stent implantation was performed in three patients with stenosis in femoral or iliac veins. Conclusion In conclusion, PMT is a safe and effective treatment modality that can be used alone in the treatment of acute DVT of lower extremities in selected cases. Further controlled trials on larger series and reports on long-term results are warranted to document the actual therapeutic potential and safety this endovascular procedure.

Highly contrasted responses of Mediterranean octocorals to climate change along a depth gradient. ROYAL SOCIETY OPEN SCIENCE 2015; 2:140493.

Abstract
Climate change has a strong impact on marine ecosystems, including temperate species. Analysing the diversity of thermotolerance levels within species along with their genetic structure enables a better understanding of their potential response to climate change. We performed this integrative study on the Mediterranean octocoral Eunicella cavolini, with samples from different depths and by means of a common garden experiment. This species does not host photosynthetic Symbiodinium, enabling us to focus on the cnidarian response. We compared the thermotolerance of individuals from 20 m and 40 m depths from the same site and with replicates from the same colony. On the basis of an innovative statistical analysis of necrosis kinetics and risk, we demonstrated the occurrence of a very different response between depths at this local scale, with lower thermotolerance of deep individuals. Strongly thermotolerant individuals were observed at 20 m with necrosis appearing at higher temperatures than observed in situ. On the basis of nine microsatellite loci, we showed that these marked thermotolerance differences occur within a single population. This suggests the importance of acclimatization processes in adaptation to these different depths. In addition, differences between replicates demonstrated the occurrence of a variability of response between fragments from the same colony with the possibility of an interaction with a tank effect. Our results provide a basis for studying adaptation and acclimatization in Mediterranean octocorals in a heterogeneous environment.

Abstract
Chest pain after thoracic trauma may be a symptom of cardiac injury or myocardial infarction. A 63-year-old healthy man had chest pain after blunt chest trauma in a motor vehicle accident. Chest computed tomography scan showed a displaced sternal fracture, lung contusion in the left upper lobe, atelectasis and consolidation in both lower lobes, and bilateral haemothorax. Electrocardiography showed ST elevation (2 mm) in leads II, III, and aVF and ST depression (2 mm) in leads I and aVL, consistent with acute inferior myocardial infarction. Urgent coronary angiography showed ostial occlusion of the right coronary artery. After the right coronary occlusion was passed with a guide wire, dissection of the right coronary artery was observed and treated with a balloon and stent to reestablish normal flow. This case emphasizes the importance of a high index of suspicion for coronary artery injury and myocardial infarction after blunt chest trauma.

Abstract
OBJECTIVES The D-dimer level, fibrinogen level, and D-dimer/fibrinogen ratio are used in the diagnosis of pulmonary embolism, but results vary. We evaluated these parameters in the diagnosis of pulmonary embolism in emergency clinic patients. METHODS In this prospective study, 200 patients (pulmonary embolism, 100 patients; no pulmonary embolism, 100 patients) had D-dimer and fibrinogen levels measured before intervention. Pulmonary embolism was diagnosed with computed tomography angiography or ventilation-perfusion scintigraphy. RESULTS Compared with patients who did not have pulmonary embolism, patients who had pulmonary embolism had significantly greater mean D-dimer level (pulmonary embolism, 6±7 μg/ml; no pulmonary embolism, 1±1 μg/ml; P⩽0·001) and D-dimer/fibrinogen ratio (pulmonary embolism, 3±3; no pulmonary embolism, 0·4±0·4; P⩽0·001), but similar mean fibrinogen levels (pulmonary embolism, 337±184 mg/dl; no pulmonary embolism, 384±200 mg/dl; not significant). In patients who had pulmonary embolism, mean D-dimer level and D-dimer/fibrinogen ratio were greater in high-risk than non-high-risk patients. With D-dimer cutoff 0·35 μg/ml, sensitivity was high (100%) and specificity was low (27%) for pulmonary embolism. With D-dimer/fibrinogen ratio cutoff 0·13, sensitivity was high (100%) and specificity was low (37%) for pulmonary embolism. CONCLUSION A D-dimer level <0·35 μg/ml may exclude the diagnosis of pulmonary embolism. At a D-dimer cutoff 0·5 μg/ml and D-dimer/fibrinogen ratio cutoff 1·0, the D-dimer/fibrinogen ratio may have better specificity than D-dimer level in the diagnosis of pulmonary embolism, but the D-dimer/fibrinogen ratio may lack sufficient specificity in screening.

Abstract
Preparation, crystal structure and magnetic properties of a heterodinuclear complex, LCu(Me2CO)Gd(NO3)3 (L = (N,N′-bis(3-methoxysalicylidene)propane- 1,2-diamine) are reported. The crystal structure of the complex was determined by X-ray diffraction methods at 200 K. (C19H22N2O4 )Cu(C3H6O)Gd(NO3)3, monoclinic, space group P21/c, with a = 9.795(9), b = 18.763(3), c = 15.579(2) Å , β = 95.297(2) V = 2850.9(7) Å3 and Z= 4. The central region of the complex is occupied by Cu(II) and Gd(III) ions which are bridged by two phenolato oxygen atoms of the ligand. The copper ion adopts a square-based 4+1 coordination mode, the equatorial N2O2 donors being afforded by the ligand while the axial position is occupied by an oxygen atom of the acetone molecule. The Gd(III) ion is deca-coordinated. In addition to the two phenolate oxygen atoms, the coordination sphere contains two oxygen atoms of the OMe side arms of L and six oxygen atoms from the three bidentate nitrate ions. The Gd... Cu separation is 3.425(3) Å and the dihedral angle between the GdO(l)Cu and GdO(2)Cu planes is 164.8°. The magnetic susceptibility of the complex was measured over the range 5 - 350 K and the observed data were successfully simulated by the equation based on the spin-Hamiltonian operator (H = -JSCu · SGd), giving the exchange integral J(Cu-Gd) = 5.6(1) cm-1. This indicates a weak ferromagnetic spin exchange interaction. The nature of the magnetic super-exchange interaction of the title compound is compared with similar [Gd(III)-Cu(II)] heterodinuclear complexes.
