Superior Mesenteric Artery Syndrome Accompanying With Nutcracker Syndrome: A Case Report
No full textINAL, MIKAIL/0000-0003-0642-7913Introduction: Superior mesenteric artery syndrome is an uncommon cause of duodenal obstruction, and its manifestations are generally associated with compression on the third part of the duodenum between the abdominal aorta and superior mesenteric artery. Case Presentation: In this report, a patient is described presenting with epigastric pain and weight loss due to superior mesenteric artery syndrome. The patient has also nutcracker syndrome, which is the compression of the left renal vein between the aorta and the superior mesenteric artery at its origin. Conclusions: In addition to an appropriate clinical history, CT findings indicating decreased aortomesenteric angle and a shortened aortomesenteric distance can suggest the diagnosis for both the superior mesenteric artery syndrome and accompanying nutcracker syndrome
Nutcracker Syndrome Accompanying Pelvic Congestion Syndrome: Color Doppler Sonography and Multislice CT Findings: A Case Report
No full textINAL, MIKAIL/0000-0003-0642-7913Nutcracker syndrome (NCS) is a rare pathology, caused by compression of the left renal vein (LRV) between the abdominal aorta (AA) and the superior mesenteric artery (SMA), due to reduction of the angle between AA and SMA. This leads to LRV varices, left gonadal vein varices and therefore, the pelvic congestion syndrome. For this reason, coexistence of NCS and pelvic congestion syndrome has been described. It manifests by hematuria, proteinuria, and nonspecific pelvic pain secondary to pelvic congestion, dyspareunia and persistent genital arousal We report a 27-year-old woman who experienced hematuria and left flank pain. The diagnosis of NCS accompanied by pelvic congestion syndrome was missed initially but later on the diagnosis was made by color Doppler ultrasound, abdominal computed tomography (CT) and CT angiography that were later performed. She refused interventional and surgical treatments, and was lost to follow up
Is there a Relationship Between Keros Classification of Olfactory Fossae Depth, Septal Deviation Angle and the Distance Between Infraorbital Foramens?
No full textINAL, MIKAIL/0000-0003-0642-7913Objectives: We retrospectively investigated the relationship between olfactory fossae depth, septal deviation angle, paranasal sinuses and the distance between infraorbital foramens (IOFs). Methods: Computerized Tomography (CT) images of 315 adult subjects were used. Paranasal sinus dimensions; Keros classification of olfactory fossae, length of Crista Galli (CG), the distance between IOFs (ZP), The distance between inferior part of crista galli and basal-inferior part of the nasal septum at the midline (CG-Sbasal) (XY), ZP/XY ratio, septal deviation side and angle were measured. Results: Keros type I was detected in males (50.3%) and Keros type II was detected in females (59.5%) mainly. In females, Keros type was highly related to the males. Both right-deviated and left deviated subjects, Keros type II (49.7% and 54.3% respectively) was the most detected Keros-type for olfactory fossae. Higher ethmoid sinus-height, maxillary sinus-width; and lower maxillary sinus-height values were related to higher Keros types. As IOFs (ZP) distance increased, Keros type also increased. Conclusion: When Endoscopic Sinus Surgery (ESS) is performed in patients having nasal septal deviation, surgeons should be careful for Keros type II olfactory fossae to avoid intracranial penetration. If possible, navigation systems should be used in these patients

No full textINAL, MIKAIL/0000-0003-0642-7913; celebi, umut orkun/0000-0003-2539-2525Objectives: In this retrospective study, we investigated the relationship between paranasal sinus, optic canal, foramen rotundum, and vidian canal measurements. Methods: Computed tomographic (CT) images of 320 adult subjects and 640 sides (right and left) were used. Paranasal sinus dimensions, optic canal (OC), foramen rotundum (FR), vidian canal (VC), bilateral FR (FRFR), bilateral vidian canal (VCVC), VC-foramen rotundum (VCFR), and VC-optic canal (VCOC) distances were measured. Results: Right VCFR (6.06 mm), and right and left VCOC values (20.34 and 20.31 mm) of the males were significantly higher than those of the females (5.50, 18.91, and 18.80 mm, respectively). Foramen rotundum, OC, and VC values were positively correlated with each other. There was also positive correlation between FR width and maxillary sinus height. Increase of OC width was related to increase in FR width and area, VCVC distance; and decrease in maxillary sinus width. There was positive correlation between FRFR, VCVC, VCFR, and VCOC distance values. There was negative correlation between VC width and area; VCVC, VCFR, and VCOC distance; and maxillary sinus, ethmoid sinus, and sphenoid sinus measurement values. As these sinuses pneumatized more, VC width and area values decreased. Conclusion: As a conclusion, the paranasal sinus, OC, VC, and FR values showed relationship with each other. Before performing craniofacial and/or skull base surgeries, CT view should be taken to evaluate the localization and the course and dimensions of the OC and vidian nerve. It should be kept in mind that in the presence of more pneumatized paranasal sinuses in CT views, VC dimensions decreased

No full textBackground & Objective:Diffusion-weighted MR imaging and apparent diffusion coefficient (ADC) values provide significant structural information about tissues in multiple sclerosis (MS).The goal of this study was to evaluate the ADC values in the hippocampus and amygdala in MS. Methods:Thirty- eightpatients with MS and 41 healthy individualswere included in the study. ADC values were measured bilaterallyfrom three different pointsin the hippocampus and amygdala in MS patients and were compared with those of the controls. An analysis of varianceposthoc test was used to analyse the differences among mean ADC values between MS and control groups.Results:The mean ADC values of both sides of thehippocampus and the left amygdala in MS patients were lower than the control group. The mean ADC values of the right amygdala in MS patients were lower than the control group, but the difference was not statistically significant.
Conclusion:We observed restricted diffusion in the hippocampus and amygdala in MS patients contrary to information in the literature
Evaluation central and peripheral pathways of smell in diabetic patients with magnetic resonance imaging
No full textDiyabetes Mellitus (DM) dünya çapında milyonlarca insanı etkileyen küresel bir halk sağlığı sorunudur. Diyabetes mellitusun makrovasküler ve mikrovasküler komplikasyonlarının yanında koku alma disfonksiyonuna yol açtığı bilinmektedir. Çalışmamızın amacı Tip 2 DM tanılı hastaların santral ve periferik koku yollarında sağlıklı bireylere kıyasla beyin manyetik rezonans görüntülemesinde (MRG) meydana gelen değişiklikleri araştırmaktır. Bu çalışmada, geçmişe dönük olarak tarananlar bireyler arasından, beyin MRG'si olan DM tanılı 123 hasta ile DM tanısı olmayan 123 kontrol olmak üzere toplam 246 birey çalışmaya dahil edildi. Olfaktor sulkus derinliği, olfaktor bulbus volümü, insular girus alanı, korpus amigdala alanı ölçümleri yapıldı. Elde edilen ölçümler istatistiksel olarak analiz edildi. Araştırmaya dahil edilen tüm bireylerin yaş ortalaması 48.9±6.9 (min:20-maks:65) yıl olup DM tanılı hastaların yaş ortalaması 48.9±7.0 (min:20-maks:65) yıl ve sağlıklı kontrollerin yaş ortalaması 48.8±6.9 (min:20-maks:64) yıl idi. Çalışma grupları arasında yaş açısından istatistiksel olarak anlamlı bir fark saptanmadı (p>0.05). İncelenen tüm bireylerin %52.8'i kadın iken %47.2'si erkekti. Aynı şekilde hem DM tanılı hastaların hem de sağlıklı kontrollerin %52.8'i kadın ve %47.2'si erkekti. Çalışma grupları cinsiyet açısından benzerdi (p>0.05). Hastalar ortalama 9.2±5.1 (min:2-maks:30) yıldır DM tanısına sahip iken HbA1c ortalaması yüzde 8.1±1.0 (min:6.5-maks:10.0) idi. Hastaların %52.8'i insülin, %77.2'si ise oral antidiyabetik (OAD) ilaç kullanırken %30.1'i hem insülin hem de OAD ilaç kullanıyordu. Araştırmaya dahil edilen bireylerde periferik koku merkezine ait yapılar olan olfaktor bulbusun volümü ve olfaktor sulkusun derinliği, santral koku merkezine ait yapılar olan insular girusun alanı ve korpus amigdalanın alanı değerlendirildi. Sağ olfaktor sulkus derinliği DM tanılı hastalarda 6.6±0.7 ve kontrol grubunda 7.4±0.7'ydi (p0.05). 52.8% of all individuals examined were female, 47.2% were male. Similarly, 52.8% of patients with DM and healthy controls were female and 47.2% were male. The study groups were similar in gender (p>0.05). Patients with DM for an average of 9.2 ± 5.1 (min: 2-max: 30) years and the mean of HbA1c was 8.1 ± 1.0 percent (min: 6.5-max: 10.0). 58% of the patients were using insulin and 77.2% of the patients were using oral antidiabetic (OAD) medication. 30.1% were patients using both insulin and OAD medication. In individuals included in the research, the volume of the olfactory bulbus and the depth of the olfactory sulcus, which are the structures of the peripheral regions of smell, the area of the insular gyrus and the corpus amygdala, the structures of the central regions of smell were evaluated. The right olfactory sulcus depth was 6.6 ± 0.7 in patients with DM and 7.4 ± 0.7 in the control group (p <0.01). The left olfactory sulcus depth was 6.2 ± 0.6 in patients with DM and 6.9 ± 0.6 in the control group (p <0.01). The right olfactory bulbus volume was 22.5 ± 7.1 in patients with DM and 30.0 ± 7.0 in the control group (p <0.01). Left olfactory bulbus volume was 22.5 ± 6.9 in patients with DM and 29.8 ± 6.1 in the control group (p <0.01). The right insular gyrus area was 303.3 ± 22.4 in patients with DM and 330.8 ± 27.0 in the control group (p <0.01). Left insular gyrus area was 300.1 ± 21.8 in patients with DM and 328.2 ± 29.7 in the control group (p <0.01). The right amygdala area was 120.3 ± 19.6 in patients with DM and 149.9 ± 17.8 in the control group (p <0.01). The left amygdala area was 121.7 ± 17.7 in patients with DM and 149.0 ± 16.9 in the control group (p <0.01). A statistically significant difference was found between the patients with DM and healthy controls in terms of all right and left olfactory sulcus depth, olfactory bulbus volume, insular gyrus area, corpus amygdala area (p <0.05). Right and left olfactory sulcus depth, olfactory bulbus volume, insular gyrus area and corpus amygdala area were significantly lower than healthy controls. This study is the first conventional magnetic resonance imaging study on DM and smell pathways, and we believe that this study will be a radiological guide in detecting smell disorder, which is often overlooked in patients with DM

Ocular blood flow in polycystic ovary syndrome
No full textOrnek, Nurgul/0000-0003-3068-1831; INAL, MIKAIL/0000-0003-0642-7913AimThe aim of this study was to evaluate whether the presence of polycystic ovary syndrome (PCOS) alters ocular blood flow parameters. Material and MethodsColor Doppler imaging of the orbital vessels was performed in 41 eyes of 41 patients with PCOS. Forty-eight eyes of 48 age-matched volunteers served as controls. The ophthalmic artery (OA), the central retinal artery and the posterior ciliary artery were examined. Ocular blood flow indices of the peak systolic velocity, diastolic velocity, end-diastolic velocity, systolic/diastolic ratio, resistive index and pulsatility index were computed. ResultsThe peak systolic velocity, diastolic velocity and end-diastolic velocity of the OA, central retinal artery and posterior ciliary artery were significantly increased in PCOS patients in comparison to the controls (all P<0.001). The mean systolic/diastolic ratio, resistive index and pulsatility index of the OA in PCOS patients were significantly decreased (all P<0.05). Ocular blood flow velocity was positively correlated with serum luteinizing hormone, follicle-stimulating hormone and total cholesterol levels. There was a significant negative correlation between serum glucose and insulin levels and ocular blood flow velocity. ConclusionOcular blood flow velocity is increased in PCOS patients and vascular resistance seems to decrease only in the OA
Evaluation of the Brachial Plexus With Shear Wave Elastography After Radiotherapy for Breast Cancer
No full textINAL, MIKAIL/0000-0003-0642-7913; kultur, turgut/0000-0002-2420-5153ObjectivesThe aim of this study was to analyze the elasticity characteristics of the brachial plexus by shear wave elastography (SWE) in patients receiving radiation therapy (RT) for breast cancer and to compare them with their contralateral brachial plexus to evaluate whether elasticity properties can be used as supporting findings for the early diagnosis of brachial plexus involvement in patients receiving RT. MethodsA prospective analysis with electromyography and SWE was performed on 23 brachial plexuses of patients receiving RT for breast cancer and their contralateral brachial plexuses. An electromyographic device was used for nerve conduction studies. Evaluations were done by the same investigator, and superficial electrodes were used in the recordings. A quantitative analysis of the brachial plexus with SWE was performed, with values in kilopascals on a color scale ranging from 0 (red, soft) to 150 (dark blue, hard) kPa. ResultsMean SWE valuesSD were 51.0 +/- 14.0 kPa for the ipsilateral brachial plexuses of patients receiving RT and 18.0 +/- 4.2 kPa for the contralateral brachial plexuses. Statistically significant differences were observed between the groups in the analysis of SWE values (P.05). ConclusionsShear wave elastography showed that the brachial plexuses of patients receiving RT were stiffer than the unaffected brachial plexuses. Brachial plexus stiffening may be associated with fibrotic processes

No full textkultur, turgut/0000-0002-2420-5153; INAL, MIKAIL/0000-0003-0642-7913;Purpose: Aim of the study is to make a clinical evaluation of parameters used in prosthesis design for the humeral component applied in arthroplasty of the proximal upper extremity. Methods: In our study the plain shoulder radiographs were used of 195 (101 male, 94 female) patients aged 18-65 years (mean age, 38.8 +/- 11.5 years; males 35.4 +/- 11.6 years, females 42.5 +/- 10.2) with soft tissue trauma, but no degenerative or structural disorder in the shoulder joint (fracture, tumour, osteoarthritis etc.). Measurements were made on the radiograph of Head Height (HH), Frontal Base Diameter of the Head (FBD), 3 points at 3 cm intervals from proximal to distal of the medullar canal at surgical neck Endosteal Diameter (ED1, ED2 and ED3 respectively), Neck-Shaft Angle (NSA) and Head-Neck Angle (HNA). Results: According to the results, in the comparison of Groups I and III except the mean values of HH and ED1 in other parameters, no statistically significant difference was determined. In the comparison of Groups II and IV except the mean values of FBD and ED1 in other parameters no statistically significant difference was determined. Conclusions: In conclusion, the success of shoulder arthroplasty is explained well by the anatomic structure and proximal humerus morphometric parameters examined in this study. In prosthesis design, the differences in age and populations should be taken
