The paper considers some articulatory features of allophones of the vowel /i/ in the Altai-Kizhi dialect (spoken in the locality Ust-Kan, Altai) of the Altai language visualized by magnetic resonance imaging (MRI). The Altai-Kizhi is the central basic dialect of the Altai literary language. In Altai, each rural locality represents a unique dialect, whose relevance of studying was emphasized by V. V. Radlov. Speech sounds of the /i/-type in the dialects of the Altai language are realized mainly as front variants with different degrees of openness. In the written Altai speech, the symbol “и” is used to denote narrow front non-labialized vowel; some variants of the Altai vowel /i/ are central-back differing in this from the Russian vowel /i/. Experimental data on the territorial dialects of the Altai-Kizhi dialect, obtained from its 6 native speakers (d1-d6) taking into account variable inherent palate height, shows both the common articulation bases of native speakers (clearly-expressed frontness) and their differences (variable openness).

<p class="abstract"><strong>Background:</strong> Shoulder pathologies can cause significant pain, discomfort, and affect the activity of daily living. The aim of this study was to compare the efficacy of clinical examination, ultrasound, magnetic resonance imaging (MRI) with shoulder arthroscopy in diagnosing various shoulder pathologies, considering shoulder arthroscopy as the gold standard tool.</p><p class="abstract"><strong>Methods:</strong> This was a prospective, comparative study conducted over 35 patients, between 18-75 years of age presenting with chronic shoulder pain or instability of more than 2 months duration. All patients were examined clinically, followed by high resolution ultrasound, MRI, arthroscopy of the affected shoulder.<strong></strong></p><p class="abstract"><strong>Results:</strong> The sensitivity and specificity of ultrasonography (USG) for diagnosing full thickness tear was 100% each and for MRI was 88% and 100% respectively. For subacromial impingement USG had sensitivity of 66.67%, specificity of 94.12%, positive predictive value of 50% and negative predictive value of 88.89%. For rotator cuff tear USG had sensitivity of 92.86%, specificity of 50%, positive predictive value of 81.25% and negative predictive value of 75% considering shoulder arthroscopy as gold standard.</p><p class="abstract"><strong>Conclusions:</strong> USG and MRI both are sensitive techniques for diagnosing of rotator cuff pathologies. USG has high accuracy in diagnosing partial thickness tears as compare to MRI. MRI proved to be superior in estimation of site and extent of tear. Considering shoulder arthroscopy as gold standard, it can be reserved for patients with suspicious of USG/MRI findings or those who may need surgical intervention simultaneously.</p>

Key Features

Silent sinus syndrome (SSS) is the spontaneous unilateral collapse of the maxillary sinus and orbital floor with complete or partial opacification of the collapsed sinus. The key features in a patient who presents with SSS are painless progressive unilateral maxillary sinus disease in the absence of rhinosinusitis, trauma, or surgery. SSS is a rare disorder but could be under-diagnosed because of a lack of recognition. SSS is characterized by spontaneous and progressive enophthalmos (“sunken” eye-eye recession into the globe) and hypoglobus (globe displaced downward; and a drop in the pupillary level), so it is common for these patients to present first to an ophthalmologist. Although mostly observed in adults, there have been reports of SSS in children. SSS in younger individuals has characteristic clinical and radiologic signs with, in many cases, abnormal intranasal anatomic characteristics on the affected side. SSS should be differentiated from other causes of spontaneous enophthalmos, such as Parry-Romberg syndrome and linear scleroderma. The aim of this report was to alert the reader to the imaging findings in patients with SSS. This syndrome is well recognized by rhinologists and to a lesser extent to ophthalmologists but remains relatively unknown to general radiologists.

ABSTRACTBackground: Low back pain (LBP) is the most common symptom which is associated with limitation of normal activities and work-related disability. Imaging techniques are often essential in making the correct diagnosis for prompt management. Plain Radiography though remain a first imaging modality, magnetic resonance imaging (MRI) due to its inherent softtissue contrast resolution and lack of ionizing radiation remains invaluable modality in the evaluation of LBP. Aim: To find the common causes of LBP in different age groups and the role of MRI in detecting the spectrum of various pathological findings. Materials and Methods: This is a prospective study done in the Department of Radiodiagnosis during a period of 2 years from July 2013 to July 2015. The study population includes all the cases referred to our department with complaints of LBP. Patients with ferromagnetic metallic implants and uncooperative cases were excluded. HITACHI 0.4 Tesla open MRI machine was used for imaging. Results and Conclusion: This study involved a total of 235 cases. There were 121 males and 114 females. The age of the patient ranged from 21 to 68 years with an average of 41.3 years. Back pain was commonly observed in the third to fifth decade. The common causes for back pain are disc herniations (disc bulge - 35.3%, disc protrusion - 39.6%, disc extrusion - 7.2%) accounting to 82.1%, followed by normal study (10.2%), vertebral collapse (traumatic - 2.1%, osteoporotic - 1.7%), infections (2.1%), and neoplasm (1.7%). MRI provides valuable information regarding the underlying causes of LBP, especially in disc and marrow pathology.

Background Tendinosis in the common extensor tendon and accompanying ligament, bone, and plica abnormalities can be observed on magnetic resonance imaging (MRI). Purpose To determine whether there is a difference between accompanying abnormalities according to the degree of common extensor tendon injury Material and Methods Patients who underwent 1.5-T MRI tests with a prediagnosis of lateral overuse syndrome were retrospectively reviewed, and 56 patients who had an injury in the common extensor tendon (CET) were included. The degree of tendon and ligament injury, muscle signal change, bone marrow signal change, presence of joint effusion, and morphological features in the presence of plica were evaluated via MRI examinations of the elbow. Results Overall, 32, 16, and eight patients had mild, moderate, and severe CET damage, respectively. As the severity of CET damage increased, the presence of joint effusion, and the presence and degree of damage to the lateral ulnar collateral ligament (LUCL) and radial collateral ligament (RCL) increased. The radiohumeral (RH) plica area was significantly larger in the group with mild CET damage. There was no statistically significant correlation between the severity of CET damage and the end of RH plica with a blind-end, coverage of one-third or more of the radius, its signal, thickness, and presence of olecranon fold. Conclusion As the severity of CET injury increases, damage to the LUCL, RCL, and the presence of effusion in the joint increases. RH plica should be evaluated in terms of concomitant pathology in patients with mild CET injuries on MRI.
