Arthroscopic excision of elastofibroma dorsi at scapulothoracic joint: a surgical technique
(2014) Cakmak, Gokhan; Ergun, Tarkan; Sahin, M.Sukru
Elastofibroma dorsi is a rare soft tissue pseudotumor which is located at the anteroinferior aspect of the scapula. In this article, we report a 19-year-old female case who had arthroscopic marginal excision of elastofibroma dorsi at the scapulothoracic joint without recurrences during follow-up. The artiaroscopic marginal excision of the elastofibroma dorsi may have good clinical results in selected cases.

High riding jugular bulb: Is it an etiological factor for benign paroxysmal positional vertigo?
(2021) Çoban, Kuebra; Kansu, Leyla; Ergun, Tarkan; Aydin, Erdinc
Introduction: High jugular bulb (HJB) is usually discovered incidentally; however, it may interfere with inner ear structures such as vestibular aqueduct (VA), facial nerve, and the posterior semicircular canal (PSCC). Objective: The aim is to investigate the incidence of HJB in benign paroxysmal positional vertigo patients with PSCC involvement (PSCC-BPPV). Materials and Methods: The study group included 53 consecutive, PSCC-BPPV patients, diagnosed in our clinic. Following the diagnosis, their high resolution computed temporal bone tomography were performed. The control group consisted of 90 patients, who attended to our clinic for various complaints, and to whom high resolution computed tomography of the temporal bone was conducted. Results: The incidence of HJB in the study group was 41.5% (n = 22). The incidence of ipsilateral HJB in this group was 28.3% (n = 15). The incidence of HJB in the control group was 11.1% (n = 10) (P < 0.001). The closest distance between HJB and PSCC canal in the control and study groups was 1.61 +/- 0.74 mm and 1.17 +/- 0.37 mm, respectively (P = 0.098). Conclusion: The HJB is significantly more frequent in PSCC-BPPV patients. Furthermore, the rate of incidence of HJB in the ipsilateral ears of these patients is significantly higher. Venous hypertension or the turbulence may cause strong pulsations, which influence the detachment of the otoconia into the PSCC.

(2014) Genctoy, Gultekin; Ayidaga, Sevgul; Ergun, Tarkan; Lakadamyali, Hatice; Erbayrak, Mustafa; Sezer, Siren; https://orcid.org/0000-0002-5145-2280; https://orcid.org/0000-0002-6165-2569; https://orcid.org/0000-0002-7326-8388; 24918131; AAJ-5551-2021; JVN-6452-2024; JYQ-2550-2024
Background/Aims: The prevalence of gallbladder stone (GBS) is shown to be increased in some studies in patients with chronic kidney disease (CKD). Nevertheless, some other studies did not confirm these findings. The controversial results about the prevalence of GBS in hemodialysis (HD) patients demand new studies to search GBS prevalence and associating risk factors in HD patients. In the present study, we aimed to investigate GBS prevalence and risk factors in our HD patients. Materials and Methods: A total of 104 HD and 149 control patients were involved. Complete physical examinations, including measurements of dry body weight and height, were done. Abdominal ultrasonography was conducted by the same experienced radiologist. Blood samples were drawn via venipuncture from the study participants after they had fasted overnight just before a midweek hemodialysis session for laboratory examinations. Results: The prevalence of GBS in HD patients was 34.6 % (36/104), and that was significantly higher than that of control group 12.9% (17/149; p=0.0001). In all study participants (HD patients and control group), patients with GBS were older than patients with no GBS (63.2 +/- 14.2 vs 53.7 +/- 16.7; p=0.0001). However, in HD patients, mean age was similar in patients with GBS and no GBS (64.3 +/- 13.8 vs 60.1 +/- 16.6; p>0.05). Patients with GBS had a higher prevalence of units of blood transfusions than patients with no GBS in hemodialysis patients (2.0 +/- 2.9 vs 0.9 +/- 1.3; p=0.047) Conclusion: The present study showed an increased prevalence of GBS in HD patients compared to healthy controls. The number of blood transfusions and autonomic neuropathy may be responsible for the increased prevalence of GBS in HD patients.

Periaortic Fat Tissue: A Predictor of Cardiac Valvular Calcification, Malnutrition, Inflammation, and Atherosclerosis Components in Hemodialysis Patients
(2015) Genctoy, Gultekin; Eldem, Olcay; Ergun, Tarkan; Arikan, Serap; 0000-0002-5145-2280; 0000-0001-5752-3812; 25940595; AAJ-5551-2021; AAM-4084-2021; AAJ-1289-2021
Cardiac valvular calcification (CVC) in end-stage renal disease is shown to be a component of malnutrition, inflammation, atherosclerosis, calcification (MIAC) syndrome. Thoracic periaortic fat tissue (T-PAFT) is shown to be increased in patients with end-stage renal disease (ESRD), and has positive correlation with MIAC. Negative correlation between CVC and vitamin D is shown in hemodialysis (HD) patients. In this study, we investigated a relationship between body composition, T-PAFT, metabolic and inflammatory parameters, and CVC in HD patients. Seventy-six HD patients (49M) were included. CVC is defined as bright echoes of >1mm on one or more cusps on echocardiography. Results were expressed as the number of calcified valves (0,1,2). Calcium, phosphorus, parathyroid hormone (PTH), C-reactive protein (CRP), albumin and 25-hydroxy vitamin D levels were studied from predialysis blood samples. T-PAFT was calculated using a method with manual definition of borders on images from multislice computed tomography. Basal metabolic rate, muscle mass, total and truncal fat mass were measured by bioimpedance analysis. There were 65.8% of patients who had CVC. Patients with CVC were older (63.5 +/- 14.6 +/- 17, P=0.02). T-PAFT (1599 +/- 596, 739.7 +/- 179mm(2), P=0.001) and CRP (15.8 +/- 11; 11.1 +/- 13.2mg/dL; P=0.04) were higher in the group with CVC. T-PAFT had positive correlations with CRP, MIAC, body mass index (BMI) and number of calcified valves, negative correlation with left ventricular ejection fraction, and no correlation with albumin, calcium, phosphorus, and PTH. The logistic regression analysis revealed that T-PAFT was a significant predictor of CVC. In this study, T-PAFT showed a positive correlation with inflammation, CVC, and MIAC score in HD patients. T-PAFT was a significant predictor of CVC.
A Rare Cause of Acute Abdominal Pain: Primary Appendagitis
(2015) Ergun, Tarkan; Lakadamyali, Hatice
Primary appendagitis epiploica - one of the causes of acute abdominal pain - is a self-limited rare benign inflammatory condition involving the colonic epiploic appendages. Their therapy is conservative and clinically mimics other conditions requiring surgery such as acute appendicitis or omental torsion. However, being a quite rare condition is the reason they are usually neglected by both the surgeon and the radiologist. However the computed tomography (CT) findings are rather characteristic and pathognomonic. Thus, to consider CT as the diagnostic modality of choice is extremely important in order to diagnose the condition and to avoid unnecessary surgical interventions. This is a paper reporting an acute abdominal pain case of primary appendicitis epiploica diagnosed using computed tomography.

Sex differences in adult craniofacial parameters
(2015) Avci, Suat; Ergun, Tarkan; Aydin, Erdinc; Kansu, Leyla; 25935592
To compare normal male and female craniofacial parameters in adults and evaluate associations of sex and intercochlear distance with other craniofacial parameters. In 60 normal adults (30 men and 30 women) who had no otitis media, craniofacial parameters were measured retrospectively on two-dimensional reformatted computed tomography scans. Compared with women, men had significantly greater mean osseous auditory tube length, cartilaginous auditory tube length, mastoid length, intercochlear distance, sella to posterior nasal spine distance, sella to basion distance, and nasopharynx sagittal area. The intercochlear distance was significantly correlated with mastoid depth, midpoint of the pharyngeal opening distance, sella to nasion distance, and nasopharynx sagittal area and inversely with angle of the auditory tube. Most men and women had Korner septum present, and mean thickness of Korner septum was significantly greater in men than women. Some craniofacial parameters, especially vertical parameters, differ with sex. These differences begin in childhood and continue in adulthood. Sex must be considered when planning a craniofacial morphologic study, and results of a craniofacial morphologic study should be evaluated with caution when there is no sex matching of the patient and control groups.

(2015) Sedef, Ali Murat; Kose, Fatih; Dogan, Ozlem; Ergun, Tarkan; Sezer, Ahmet; Mertsoylu, Hoseyin; Muallaoglu, Sadik; Besen, Ayberk; Ozyilkan, Ozgur; 25798275
Soft tissue sarcomas (STS) are a group of rare mesenchymal cancers that include approximately 50 histological types and account for 1% of all adult cancers. The standard curative treatment option for localized disease is surgical resection and, if a surgically removed tumor exhibits high-risk characteristics, adjuvant chemotherapy and radiotherapy may be administered. Sarcoma presenting at an advanced stage has a dismal prognosis and survival has not markedly improved over the last 20 years. The standard first-line treatment for advanced STS, other than gastrointestinal stromal tumors, is cytotoxic chemotherapy. Therapies targeting pro-angiogenic factors have been a focus of drug development for STS over the last few years. Pazopanib, a multitargeted tyrosine kinase inhibitor, is a novel treatment option for patients with metastatic STS in the second-line setting. This is a presentation of 2 case reports of patients with metastatic STS who responded well to treatment with pazopanib.
