Comparison of Mechanical Stabilization of the Mandibular Angulus Fracture Fixation, With Titanium Plates and Screws, Resorbable Plates and Screws, and Bone Adhesives

Mandibular fractures mostly occur at the angulus man-dibula with a concurrent symphysis or corpus fracture on the opposite side. Misapplication can damage the nerves, adjacent teeth, soft tissues, and result in permanent tooth germs. In children, growth centers can be damaged, and this may result in asymmetry and retardation in growth and development. The aim of this study was to compare the mechanical stabilization after different techniques were used to create the mandibular angle fracture fixation and to create oblique fractures at mandible angles. This study included 32 hemi-mandibles that were divided into 4 groups with 8 units per group. All of the hemi-mandibles were fixated using different techniques; titanium mini plates and screws, resorbable mini plate and screws, and resorbable mini plates and cyanoacrylate bone adhesive only. The fixated mandibles were tested under molar masticatory forces, and their stabilization endurance was assessed. There were no significant differences in titanium mini plaque screw and resorbable plaque screw techniques under 40 N force. Resorbable and titanium plates and screws did not have any advantage over each other in terms of biomechanical behaviors. It is suitable to use adhesives in the reduction of complicated but nonload-bearing areas. The adhesive used in this study can adhere to the bone but should be further evolved for clinical use

Computerized Tomography Based Novel Features in Thyroid Cancer

Ultrasound imaging and Fine Needle Aspiration Biopsy, which used for diagnosis of thyroid cancer, don't ensure sufficient sensitivity and specificity. Due to this fact, many patients undergo unnecessary thyroid removal. In this study, it is aimed to find new features based on non-invasive Computerized Tomography. 52 nodular goiter patients who underwent thyroid removal surgery with suspicion of cancer were included in the study. Resected fresh thyroid tissues were imaged using Computerized Tomography (CT). In CT images, background and noise estimation as well as elimination were applied. Thyroid images were automatically segmented and modified histograms were calculated. Afterwards, features based on these histograms were calculated and it is proposed that these features can be used to discriminate malignant and benign thyroids. Moreover, as an indirect finding of histograms, it is concluded that thyroidal volume can be a useful criterion in determination of malignancy

Analysis of EMG Signals in the Quadratus Lumborum Muscle of Healthy Subject with Functional Leg Length Discrepancy

The purpose of this study was to analyze the electromyography (EMG) signals of the Quadratus Lumborum (QL) muscle activity on leg length discrepancy (LLD) and pelvic asymmetry. So we investigated whether pelvic asymmetry might cause injuries in lumbar spine and lower extremity. This was a randomized control experiment, total 50 (25 males and 25 females) datas were analyzed. All participants were right handed. Iliac crest levels were assessed by manually and LLD measurement was used with tape. EMG signals of the QL muscle were taken in the resting position without any activity intentionally in the prone position. Analysis of the data revealed that the QL muscles activity were higher at the pelvic elevation on the right side than on the left side. While there was a shortness in the lower extremity 27% of the cases on the right condition but it was statistically determined that 23% of the left side was short. At the same time, 100% of the cases in the lower extremity on the right side were found to be in the right iliac crest elevation position. Unilateral hyperactivity of the QL muscle leads to instability of the spine and pelvic muscles and causing pelvis asymmetry and functional LLD As a result, unbalanced loading on the spine and lower extremities may result in injury

We aimed to explore the factors involved in the development of urgent hemodialysis in patients on maintenance HD and to compare clinical differences between patients with arteriovenous fistula (AVF) and permanent tunelled catheter

Nuclear Medicine In Prosthesis Infections

Protezi bulunan hastalarda aseptik gevşeme ile enfeksiyonu ayırt etmek önemlidir çünkü tedavileri çok farklıdır. Bu iki antiteyi birbirinden ayırmanın bazı güçlükleri vardır. Periferik kanda artmış lökosit, eritrosit sedimantasyon hızı ve C reaktif protein seviyeleri enfeksiyon için ne sensitif ne de spesifiktir. Eklem aspirasyonu ile yapılan gram boyama ve kültür %90ın üzerinde spesifiteye sahip olsa da sensitivitesi %28-%92 arasında seyreder. Bilgisayarlı tomografi ve manyetik rezonans görüntüleme yöntemlerinin kullanımı ise metalik artefakt sebebiyle sınırlıdır. Radyonüklid görüntüleme yöntemleri ise ortopedik metalik artefaktlardan etkilenmezler ve şüpheli eklem protezi enfeksiyonu olgularında günümüzde kullanılırlar. Kemik sintigrafisi problemli eklem protezini tespit etmede sensitif bir yöntemdir fakat kesin tanıyı koymada başarısızdır. Bu yüzden kemik sintigrafisi tarama testi olarak veya diğer radyonüklid çalışmalarla kombine kullanılır. Kombine galyum/kemik sintigrafisi tek başına kemik sintigrafisine göre hafif düzeyde tanıya olumlu katkı yapmıştır. Günümüzde yaklaşık %90 doğruluğa sahip olan işaretli beyaz küre/kemik iliği sintigrafisinin kombine kullanımı eklem protezi enfeksiyonu tanısında tercih edilen radyonüklid görüntüleme yöntemidir. 18Fflorodeoksiglukoz pozitron emisyon tomografisi üzerinde araştırmalar devam etmektedir, eklem protezi enfeksiyonlarındaki yeri henüz tartışmalıdır.Differentiating aseptic loosening from infection in patients with prosthesis is important because their treatments are very different. Differentiating these two entities have some difficulties. Increased peripheral blood leukocytes, erythrocyte sedimentation rate, and C-reactive protein levels are neither sensitive nor specific for infection. Although joint aspiration with Gram stain and culture has a specificity of 90% or more, its sensitivity ranges from 28% to 92%. Computed tomography and magnetic resonance imaging modalities are limited by hardware-induced artifacts. Radionuclide imaging is not affected by orthopedic hardware and is the current imaging modality of choice for suspected joint replacement infection. Bone scintigraphy is sensitive for identifying the failed joint replacement, however, can not be used to determine the definite diagnose. Thus, bone scintigraphy is used as a screening test or combined with other radionuclide studies. Combined bone and gallium imaging mildly improve the diagnose over bone scintigraphy alone. Presently, combined leukocyte/marrow imaging, with approximately 90% accuracy, is the radionuclide imaging procedure of choice for diagnosing prosthetic joint infection. 18F-fluorodeoxyglucose positron emission tomography has been investigated. Its value in the diagnosis of prosthetic joint infection is debatable

BILATERAL MOLARIFORM SUPERNUMERARY TEETH IN THE ANTERIOR MAXILLA: A REPORT OF TWO CASES

Supernumerary teeth are additional teeth besides the normal series and can be found in any region of the dental arch. Supernumerary teeth can be classified according to their form and locations. Early diagnosis and treatment of patients with supernumerary teeth may prevent or minimize complications. The treatment options depend on the type and position of the supernumerary tooth and its effect on the adjacent structures. Two male patients were referred to our clinic due to swelling in their maxillae and interrupted eruption of teeth. Upon radiological examination of the patients, impacted supernumerary teeth were found. Surgical removal of these teeth were perfomed and they were found to be molariform. We aim to present the two rare cases of molariform supernumerary teeth in this article

Efficiency of radioactive I-131 therapy in geriatric patients with toxic nodular goiter

WOS: 000327389100021PubMed: 23211880Background and aims: The success of I-131 therapy in geriatric patients who were referred to an endocrinology clinic with toxic nodular goiter and who lived in iodine-deficiency regions was studied. Materials and methods: Patients older than 60 years who received I-131 therapy were included via retrospective data analyses. Fifty-nine patients between 60 and 82 years of age were enrolled in the study. The patients received an oral capsular form of I-131 (10-25 mCi) and were followed up for 1 year with clinical and laboratory results. Euthyroid or hypothyroid status at the end of the year after treatment was deemed to be a response to treatment. Results: Of the 21 (36%) male and 38 (64%) female patients, 29 (49%) had a solitary toxic nodule and 30 (5 1%) had toxic multinodular goiter. Twenty-nine (49%) of the patients received propylthiouracil therapy. At the end of the year, 38 (64%) patients were euthyroid, 11 (19%) were hypothyroid, and 10 (17%) were thyrotoxic. Forty-nine (83%) patients who were euthyroid and hypothyroid were considered responders. Conclusion: Geriatric patients with toxic nodular goiter were shown to have a high response rate to I-131 therapy. Thus, we suggest that radioactive iodine treatment should be the first-line treatment in these patients. (C) 2012, Editrice Kurti

Resistin predicts ischemia in myocardial perfusion scintigraphy

Aim: Resistin plays a role in the pathogenesis of coronary artery disease and is related to mortality and morbidity through a number of mechanisms. We hypothesize that plasma resistin levels are increased in the presence of ischemia, as measured by GATED singlephoton emission computed tomography myocardial perfusion scintigraphy (SPECT MPS), in comparison with nonischemic subjects. Materials and methods: Fasting intravenous blood samples of patients were drawn before a stress test. An ELISA kit was used for the assays. All patients underwent a technetium 99m-sestamibi GATED SPECT MPS study with a 1-day stress-rest protocol. Images were analyzed visually and patients were assessed as ischemic or nonischemic. Resistin levels were presented as medians (25th75th percentiles) and were compared using the MannWhitney U test. Results: Plasma resistin levels were higher in the ischemic group (n 47) than in the nonischemic group (n 67) [9.04 µmol/L (6.2711.8 µmol/L) vs. 3.56 µmol/L (0.397.93 µmol/L), respectively; P < 0.001). We showed that plasma resistin levels (OR 1.26, 95% CI: 1.131.41; P < 0.001) and METs (OR 0.82, 95% CI: 0.700.92; P 0.021) were independent predictors of ischemia. No linear correlation was found between plasma resistin levels and GATED SPECT or stress test parameters. Conclusion: Increased baseline resistin levels are independently related to presence of ischemia but are not related to the extent or severity of ischemia, or other functional parameters such as poststress ejection fraction, end systolic, and end diastolic volumes
