Pelvik kemik yapılarının bölütlenmesi ve pelvik açılarının otomatik ölçümü
No full textPelvik kemik yapısı, iskelet sistemimizin temelini oluşturur ve bu yapının radyolojik ve
ortopedik olarak doğru değerlendirilmesi büyük önem taşımaktadır. Bu yapının
değerlendirilmesinde ve Pelvik kemik hastalıklarının tanı ve tedavi sürecinde bazı
Asetabulum açılarından yararlanılır.
Bu çalışmada, hem Pelvik kemik yapısı ile ilgili yeni bir tıbbi açı ölçüm metodu
tanımlanmış, hem de bu yeni geliştirilen tıbbi metodun teknik gösterimi olarak
tamamen otomatik olarak çalışan yeni bir açı ölçüm metodu geliştirilmiştir. Bu
otomatik açı ölçüm metodu, Pelvik kemik yapılarının bölütlenmesi ve Pelvik açılarının
otomatik ölçümü olarak iki kısımdan oluşmaktadır. Pelvik kemik yapılarının
bölütlenmesi için İşaretçi tabanlı Watershed bölütleme metodu ve Zernike moment
şekil tanımlayıcı metodlarının birlikte kullanılması ile Obturator gözlerinin tamamen
otomatik olarak bölütlenmesi sağlanmıştır. Bu çalışmanın ikinci kısmını ise
Asetabular açılarının tam otomatik olarak ölçümü oluşturmaktadır. Bu çalışmada
Asetabular açılarının, sağlıklı hastalar için normal tıbbi açı ölçüm değerleri, hem
uzmanların elle ölçüm metodu hem de geliştirilen yeni otomatik açı ölçüm metodu

Pelvic bone structure is the fundamental part of our skeletal system and the accuracy
of radiological and orthopaedical evaluation of this system is very important.
Asetabulum angles are used for the evaluation of this structure and the diagnosing
and treatment phases of Pelvic bone diseases.
In this study, both a new medical angle measurement method is defined and a new
fully automated angle measurement method for this medical method is developed.
This automated method consists of two parts as the segmentation of Pelvic bone
structure and the automated measurement for Pelvic angles. The fully automated
segmentation method for Obturator Foramen is developed with the integrated usage
of the Marker-based Watershed segmentation method and Zernike moment feature
descriptor for Pelvic bone structure segmentation. The second part of this study is
the automated measurement of the Asetabulum angles. In this study, the Asetabulum
angles are measured both with the traditional method by clinicians and by the
automated method for the healty patients and then the normal medical
measurements are extracted separately. Also, the angle measurement results are
obtained by using two angle measurement methods for patients which have hip
dysplasia for adults and children
The first part of the proposed angle measurement method which is the segmentation
of Obturator foramen is tested on 100 Pelvic X-ray image and the segmentation
accuracy is obtained %96. Also, the evaluation of the automated angle measurement
method is performed by statistically and p >0.005 value is obtained between the
manual angle measurements and the results of the automated angle measurement
method for each angle measurement. Therefore, there isn’t any significant difference between the manual angle measurements and the automated angle measurement
method. As a result of this study, a new fully automated angle measurement method
is developed for accurate diagnosing and treatment of different Pelvic bone diseases
by clinicians
Effects of vaginal cylinder position on dose distribution in patients with endometrial carcinoma in treatment of vaginal cuff brachytherapy
Get PDFPurpose: To investigate the impact of different cylinder positions on dosimetry of critical structures in patients with endometrial carcinoma undergoing three-dimensional image-based vaginal cuff brachytherapy (VCB).
Material and methods: We delivered VCB at a dose of 4 Gy to a depth of 5 mm in the vaginal cuff of 15 patients using three different cylinder positions (neutral [N], parallel [P], and angled [A]) according to the longitudinal axis of the patient. We analyzed the dose-volume distribution and volumetric variability of the rectum and bladder. We converted the total doses to equivalent doses in 2 Gy (EQD(2)) using a linear-quadratic model (a/b = 3 Gy).
Results: The mean rectum volume for the N, P, and A positions was 68.2 +/- 22.7 cc, 79.3 +/- 33.7 cc, and 74.2 +/- 29.6 cc, respectively. The mean rectum volume for the P position was significantly larger than that for the N position (p = 0.03). Relative to the N position, the A position resulted in a lower total EQD(2) in the highest irradiated 2 cc (D-2cc; p = 0.001), 1 cc (D-1cc; p = 0.004), and 0.1 cc (D-0.1cc; p = 0.047) of the rectum. Similarly, the P position resulted in a lower EQD(2) in the D-2cc (p = 0.018) and D-1cc (p = 0.024) of the rectum relative to the N position. In the bladder, the P position resulted in a higher EQD(2) in the D-2cc, relative to the N position (p = 0.02). There was no dosimetric difference between the P and A positions in either the rectum or the bladder.
Conclusions: Vaginal cuff brachytherapy in the P and A positions is significantly superior to that in the N position in terms of rectum dosimetry. The bladder dose in the N position is considerably lower than that in the other positions

Get PDFWe present new accretion solutions of a polytropic perfect fluid onto an f(R)-gravity de Sitter-like black hole. We consider two f(R)-gravity models and obtain finite-period cyclic flows oscillating between the event and cosmological horizons as well as semi-cyclic critical flows executing a two-way motion from and back to the same horizon. Besides the generalizations and new solutions presented in this work, a corrigendum to Eur. Phys. J. C (2016) 76:280 is provided
Hyperglycemia in Hospital: Diagnosis, Classification, Clinical Implications and Treatment
No full textHyperglycemia is a well-recognized risk factor for hospital-related complications, prolonged stay in the hospital and even mortality. The patients with in-hospital hyperglycemia may be categorized into three groups: i) Patients who have been diagnosed as having diabetes mellitus (DM) before admission; ii) Patients with newly diagnosed DM; and iii) Patients with stress hyperglycemia. The release of stress hormones, such as cortisol, catecholamines, glucagon, growth hormone and the related acceleration in gluconeogenesis and glycogenolysis, medications used for the treatment of primary diseases, such as glucocorticoids and vasopressors, are all claimed to be responsible for the development of in-hospital hyperglycemia. Glucose normalization with insulin therapy has been demonstrated to significantly decrease the morbidity and mortality in all the three groups. Therefore, it is recommended to monitor blood glucose levels for all hospitalized patients irrespective of the accompanying DM diagnosis
Enhancer of zeste homologue 2 (EZH2) expression in synovial sarcomas as a promising indicator of prognosis
Get PDFSynovial sarcoma (SS) is a type of soft-tissue sarcoma, often linked to poor survival. Although overexpression of enhancer of zeste homologue 2 (EZH2) has been associated with poor prognosis in different tumors, a few studies investigated this link in SS. Here, we analyzed the relationship between EZH2 expression and prognostic factors in SS. We included 29 patients with SS. Immunostaining of EZH2 was performed with (D2C9) XP (TM) Rabbit mAb antibody, and the results were classified as low EZH2 expression (negative or weak expression) and high EZH2 expression category (moderate or strong expression). Analysis of survival in relation to prognostic factors was performed with Kaplan-Meier survival curves and Cox proportional hazard regression analysis. Our sample included 19/29 female and 10/29 male patients, with age range 16-63 years. The tumor diameter ranged from 2 to 15 cm. Necrosis was observed in 15/29 cases. Sixteen cases had > 10 mitoses per 50 high-power fields (HPFs). Out of 29 cases, 14 showed low and 15 had high EZH(2) expression. Statistically significant results were obtained for the association between the presence of metastasis and necrosis (p = 0.042), high EZH2 expression and distant metastasis (p = 0.018), high EZH2 expression and necrosis (p = 0.016), and high EZH2 expression and the tumor size > 5 cm versus tumor size <= 5 cm (p = 0.014). Patients with all of the following: the tumor size <= 5 cm, low EZH2 expression, and without necrosis and distant metastasis had significantly longer survival time. Our results are consistent with previous studies, suggesting that EZH(2) overexpression is an indicator of poor prognosis in SS
Effects of platelet-rich fibrin on healing of intra-bony defects treated with anorganic bovine bone mineral
No full textAnorganic bovine bone mineral (ABBM) is extensively used in the treatment of intra-bony defects. Platelet-rich fibrin (PRF) is a new-generation platelet concentrate with a simplified technique. Although certain studies have reported the use of PRF in the treatment of intra-bony defects, to date, none of them have evaluated its additive effects with ABBM. Therefore, a randomised, split-mouth clinical trial was conducted to compare healing of intra-bony defects treated with an ABBM-PRF combination with healing of those treated with ABBM alone. By using a split-mouth design, 15 paired intra-bony defects were randomly treated with either ABBM alone (control group) or ABBM-PRF combination (test group). Following clinical parameters and radiographical measurements were recorded at baseline and 6 months after treatment: plaque index (PI), gingival index (GI), probing depth (PD), gingival recession (GR), clinical attachment level (CAL), vertical bone loss, depth of defect and defect angle. Preoperative clinical and radiographical measurements were similar for the test and control groups. Statistically significant reductions in GI, PD, CAL, vertical bone loss, depth of intra-bony defect and widening of defect angle were detected after treatment in both groups. With respect to inter-group analysis, gain in CAL was significantly greater in the test group than in the control group, whereas no inter-group differences were observed in any other parameter. The results of this study indicate that both therapies are effective in the treatment of intra-bony defects
Herpes Zoster Brachial Plexopathy: Direct Steroid Injection
No full textHerpes zoster (shingles) is a viral disease, characterized by painful skin eruptions and neuropathic sensory symptoms. Motor involvement and brachial plexus involvement in herpes zoster are rare conditions. Together with antiviral medication and pain therapy, palliative and supportive modalities take an important role in the treatment of herpes zoster. It is well documented in previous reports that oral or intravenous steroid administrations may be additive in management. In this case report, positive effects of direct steroid injection onto the brachial plexus via ultrasonography guidance in a patient with motor weakness due to herpes zoster involvement of brachial plexus is presented
Schistosomiasis and pulmonary hypertension
No full textSchistosomiasis is one of the most prevelant parazitic diseases in the world. It is endemic in more than 70 countries, and more than 200 million people worldwide are infected with Schistosoma. Pulmonary hypertension (PHT) is one of the chronic complications of schistosomiasis. The exact pathogenesis of schistosomiasisassociated pulmonary hypertension (S-PHT) remains unclear, although several mechanisms such as parazitic arterial embolisation, pulmonary arteriopathy, and portopulmonary hypertension have been suggested. Pathological pulmonary vascular changes in S-PHT were found similar to those in idiopathic pulmonary arterial hypertension (IPAH). The fact that schistosomiasis is one of the most common causes of pulmonary arterial hypertension (PAH), particularly in the developing countries, underlines the importance of enhancing our knowledge on this disease. Developments in the treatment of PAH have resulted in improved prognosis and significant increase in life expectancy and quality of life in the last two decades, which has enhanced the importance of S-PHT. Schistosomiasis is treated with praziquantel. Nevertheless, there is limited evidence that this treatment is effective for PHT. Although antihelmintic medications do not lead to significant improvement, they have beneficial effects and may slow down disease progression. Using PAH-specific treatments in the patients with schistosomiasis-associated PAH (S-PAH) can improve prognosis. However, inadequate clinical studies and limited sources in the endemic regions restrict extensive usage of these expensive medications. Further studies are required to determine the efficacy of these treatment modalities
