COMPARISON OF SUBJECTIVE ESTHETIC PERCEPTIONS OF DENTISTS WITH DIFFERENT GENDER AND CLINICAL EXPERIENCES WITH OBJECTIVE DENTOLABIAL ESTHETIC MEASUREMENTS

Objective: The aim of this study is evaluate the consistency of certain measurable dentolabial criteria between the esthetic values accepted in the literature and the subjective opinions of physicians. Materials and Methods: Four associated professors and four research assistants in the field of Prosthodontics were selected as the examiners of the study. Smile photos taken from 200 volunteer participants with only the mouth region were examined. The results of measurement of the curvature of the incisal edge and lower lip parallelism, incisal edge and lower lip contact, laugh line, buccal corridor and interincisal line and midline variables and subjective assessments of the evaluators were compared with Cochran Q test. Results: Esthetic perception is subjective and there was a significant correlation between objective measurements and subjective perception in the incisal edge and lower lip parallelism, laugh line and buccal corridor variables. No statistically significant difference was found between male and female individuals, similarly between specialists and research assistants. Conclusion: There is no consensus between esthetically objective findings and subjective views

Assessment of the coronary venous system by using cardiac CT

PURPOSEWe aimed to investigate the coronary venous system and its variations by using dual source computed tomography (CT).MATERIALS AND METHODSRetrospective assessment was carried out on 339 patients who underwent coronary CT angiography using 128-slice dual source CT for suspected coronary artery disease. The examinations were performed according to routine imaging protocols used to evaluate coronary arteries. The coronary venous system was evaluated in each case using maximum intensity projection and volume rendering technique multiplanar reformation reconstructions. In each patient, the presence and calibration of normal anatomy, as well as the variations of the coronary sinus, middle cardiac vein, small cardiac vein, posterior cardiac vein, great cardiac vein, anterior interventricular vein, posterolateral vein, left marginal vein, and anterolateral vein were recorded.RESULTSThe coronary sinus, middle cardiac vein, great cardiac vein, and anterior interventricular vein were visualized in all of the patients. In all cases, one of the lateral or posterolateral veins of appropriate localization and diameter for cardiac resynchronization therapy was detected. The posterior cardiac vein was visualized in 87% of the cases, the left marginal vein in 87.9%, and the small cardiac vein in 20%. There was no significant difference in the diameters or visibilities of the coronary veins in terms of age.CONCLUSIONThe coronary venous system and its tributaries may be examined in detail using CT angiography examination performed according to the routine coronary CT angiography protocol used for dual source CT. Dual source CT may be a valuable tool for evaluation of the coronary veins prior to invasive procedures that are directed at the coronary venous system

Susceptibility-Weighted MR Imaging: Added value of susceptibility signals in diagnosis of hemorrhagic lesions of the brain

Susceptibility-weighted imaging (SWI) is a relatively new high-spatial resolution 3D gradient-echo MR imaging technique that uses both magnitude and phase information. This technique exploits the magnetic susceptibility differences of various tissues or substances, such as blood products, iron, and calcification. It is particularly useful to visualize intravascular venous deoxygenated blood as well as extravascular blood products. Therefore, SWI provides additional diagnostic and prognostic data in the evaluation of a wide variety of neurologic disorders including various hemorrhagic lesions seen in traumatic brain injury, coagulopathic or other hemorrhagic disorders, occult vascular malformations, stroke, hypoxic-anoxic injury, neoplasms, and neurodegenerative disorders. We present a review with selected cases to illustrate and discuss the clinical usefulness of SWI in hemorrhagic lesions of the brain

Comparison of the Micro-Shear Bond Strength of Resin Cements to CAD/CAM Glass Ceramics with Various Surface Treatments

This study aimed to compare the effect of acid etching, sandblasting, or silica coating on the micro-shear bond strength of dual-cured resin cements to computer-aided design and computer-aided manufacturing (CAD/CAM) glass ceramic materials. Feldspathic, lithium disilicate, and zirconia-reinforced CAD/CAM ceramics were divided into four groups: control group (C), no surface treatment; hydrofluoric (HF) group, 5% HF acid-etched; sandblasting (SB) group, abraded with 50 µm aluminum oxide (Al2O3) particles; silica-coated (CJ) group, abraded with 30 µm silica-modified Al2O3 particles. Roughness values were obtained by using a profilometer. The cements were condensed on the surface-treated specimens and a micro-shear bond test was conducted. The ceramic material (p p < 0.001) significantly affected the micro-shear bond strength values. HF acid etching can be recommended for the surface pretreatment of feldspathic, lithium disilicate, and zirconia-reinforced CAD/CAM ceramics. Better bond strengths can be obtained with HF acid etching than with sandblasting and silica coating

A rare form of breast fibroadenoma: İntraductal fibroadenomatosis

In this paper, we present an unusual form of fibroadenoma in a 31-year-old female. Ultrasonography revealed multiple, hypoechoic,solid tubular struc- tures that converged toward the areola. The mass removed totally. Histo- pathological diagnosis was intraductal form of fibroadenoma. To the best of our knowledge, no reference to this histopathologic and radiologic findings has previously been reported in the literature.Bu yazıda 31 yaşındaki bayan hastada fibroadenomun nadir bir formunu su- nuyoruz. Ultrasonda areolaya doğru birleşen multipl, hipoekoik, solid, tubu- ler yapılar saptanmıştır. Histopatolojik tanısı fibroadenomun intraduktal for- mudur. Bildiğimiz kadarıyla literatürde histopatolojik ve radyolojik bulguları içeren kaynak mevcut değildir

Overin dev mikst tip seks kord stromal tümörü

Sex cord-stromal tumors account for approximately 7% of all primary ovarian tumors. Sertoli-Leydig Cell Tumors and Granulosa cell tumors are subtype of sex cord stromal tumor of the ovary. Sertoli-Leydig Cell Tumors account for less than 0.2-0.5% of all primary ovarian neoplasms. Granulosa cell tumors account for 3-5% of all primary ovarian neoplasms. Mixed subtype of sex cord stromal tumors are very rare a condition. Very few case reports have been documented in the literature so far. Despite the rather large lesion at the time of diagnosis in sex cord stromal tumors, 80-90% of patients will present at stage 1. A case of 21-year-old nullipar woman who presented with a 2-month history of a pelvic pain, menorrhagia, rapidly increasing abdominal distention, and alopecia. Pelvic ultrasonography and magnetic resonance imaging revealed 175x170x93 mm septal cystic mass in the left ovary. the patient underwent left unilateral salpin - goophorectomy because of huge septal cystic mass and fertility preserving surgery. in histopathological examination these masses were evaluated as mixed (Granulosa cell/Sertoli-Leydig Cell Tumors) sex cord stromal tumor. This case was chosen and reported due to its rarity and clinical properties.Seks kord stromal tümörler; tüm over tümörlerinin yaklaşık %7’sini oluştururlar. Sertoli-Leydig hücreli tümörler ve granüloza hücreli tümörler overin seks kord stromal tümörlerinin alt tiplerindendir. Sertoli-Leydig hücreli tümörer, tüm over tümörlerinin %0,2-0,5’den daha azını oluştururlar. Granüloza hücreli tümörler ise tüm over tümörlerinin %3-5’ini oluştururlar. Seks kord stromal tümörün alt tiplerinin birlikte izlenmesi ise çok çok nadir bir durumdur. Bu nedenle bu güne kadar literatürde çok az sayıda vaka bildirilmiştir. Seks kord stromal tümörler tanı konulduğunda büyük kitleler halinde olmasına rağmen, %80-90’ının evre 1’de olduğu gözlenmektedir. Olgumuz 2 aydır devam eden pelvik ağrı, menoraji, giderek artan karın şişliği ve alopesi şikayetleri olan 21 yaşında nullipar hastadır. Hastanın pelvik ultrasonografi ve manyetik rezonans görüntülemelerinde sol overde 175x170x93 mm boyutlarında septalı kistik kitle izlenmiştir. Kistinin septalı olması ve fertilite koruyucu cerrahinin istenmesi nedeniyle sol uniateral salpingooeferektomi uygulanmıştır. Histopatolojik ncelemede mikst tip (Granüloza hücreli/Sertoli-Leydig hücreli tümör) seks kord stromal tümör olarak değerlendirilmiştir. Bu olgu nadir görülmesi ve klinik özellikleri nedeni ile yayınlamaya uygun bulunmuştur

Mesane Çıkışı Obstrüksiyonunun Non-İnvaziv Tanısında İnravazikal Prostatik Protrüzyonun Önemi: Semptomlar ve Üroflowmetrik Sonuçlarla Koralasyon

Background: To investigate the relationship among intravesical prostatic protrusion (IPP) measured using transabdominal ultrasound (TAUS) and symptoms and results of uroflowmetry in patients with lower urinary tract symptoms (LUTS). Material and Methods: Questions including international prostate scoring system (IPSS) asked to patients presenting with LUTS and answers were recorded. TAUSs were performed by radiologists. IPP measurements were done and then full-filled bladder volume (BV) and post residual urine volume (PRUV) measurements were performed. The patients were classified as with low, medium and high obstructive symptoms according to their IPSS values. Their PSA values, peak and medium urinary flow rate (PUFR, MUFR) values were recorded. Variables were compared with non-parametric tests using SPSS 19.0. P;lt;0.05 was considered to indicate a significant difference. Results: There was no significant correlation between patients’ age, full-filled BV and other variables. PRUV, volume of prostatic gland, PSA values and IPP measurements were strongly correlated to each other. There were significant negative correlation between PUFR and MUFR and other variables. Most significant correlation was seen between IPP and IPSS (r: 0.938, p: 0.001). Conclusions: In patients with LUTS, the IPP assessed by TAUS is a better, easy to apply, useful and more reliable predictor of bladder outlet obstruction than the other variables assessed.Amaç: Alt üriner sistem yakınmaları (AÜSY) olan hastalarda transabdominal ultrasonografi (US) kullanılarak ölçülen intravezikal prostatik protrüzyon ile (İPP), hastanın yakınmaları ve üroflowmetrik sonuçları arasındaki ilişkiyi araştırmaktır. Materyal ve Metot: AÜSY olan 102 hastaya uluslararası prostatik semptom skorlamasına (international prostatic symptom scoring: IPSS) ait sorular yöneltilip yanıtları kaydedilmiştir. Abdominal US incelemede İPP ölçümleri alınmıştır. Ardından dolu mesane hacmi, post-voiding rezidüel idrar (PVR) miktarı ölçülmüştür. IPSS değerlerine göre olgular düşük, orta ve şiddetli semptomlara sahip 3 grupta sınıflandırılmıştır. Hastaların PSA değerleri, maksimum (MİAH) ve ortalama idrar akım hızlarını (OİAH) içeren üro-flowmetri sonuçları ve yaşları kaydedilmiştir. SPSS 19.0 kullanılarak, değişkenler arasındaki ilişkiler non-parametrik testlerle analiz edilmiş, p0,05 değeri istatistiksel açıdan anlamlı kabul edilmiştir. Bulgular: Hastalarda, gruplar arasında hasta yaşı ve dolu mesane hacminin diğer parametrelerle anlamlı korelasyonu mevcut değildir. PVR, prostat volümü, PSA ve IPP değerleri bakımından gruplar arasında istatiksel olarak anlamlı pozitif korelasyon mevcuttur. Maksimum ve ortalama idrar akış hızlarıyla diğer parametreler arasında anlamlı negatif korelasyon saptanmıştır. İPP ile IPSS arasındaki pozitif koreleasyon diğer parametrelere göre en belirgin olanıdır (r: 0,938, p: 0,001). Sonuçlar: Bu çalışmaya göre AÜSY’si olan ve IPSS semptom skorlamasına göre değerlendirilen hastalarda transabdominal US’lerde elde edilen İPP ölçümleri mesane çıkışı obstrüksiyonunun şiddetini belirlemede kolay uygulanabilir, kullanışlı ve güvenilir bir belirleyicidir
