OBJECTIVE: Mitochondrial open reading frame of the 12s ribosomal RNA type-c (MOTS-c) is a novel identified mitochondrial signal transmission peptide that plays an important role in glucose, amino acid and lipid metabolism. In this study, we aimed to investigate the relationship of circulating MOTS-c level with noninvasive scores of fibrosis and the components of metabolic syndrome (MetS) in patients with metabolic dysfunction-associated fatty liver disease (MAFLD). PATIENTS AND METHODS: This was a single-center cross-sectional study, and the participants were divided into two groups based on their liver ultrasound results: the fatty liver group and the healthy control group. The MOTS-c level was measured by the ELISA method. Non-alcoholic fatty liver disease fibrosis score (NFS) and fibrosis 4 (FIB-4) were used to determine the level of liver fibrosis. Statistical analyses were performed using Statistical Package for Social Science 15.0 package program. RESULTS: One hundred fifty patients (male, n=57) with MAFLD [median age 41.0 (14) years] and 84 healthy controls (male, n=34) [median age 36.0 (22) years] were included in this study. Patients with MAFLD had significantly lower MOTS-c levels than the healthy controls (p=0.009). The MOTS-c level was significantly lower in subjects with MetS (n=48) compared to those without MetS (n=186) (p=0.01). In the total population (n=234), MOTS-c levels negatively correlated with the presence of MAFLD, NFS, FIB-4, and components of MetS. CONCLUSIONS: Individuals diagnosed with MetS and MAFLD tend to have lower levels of MOTS-c. Additionally, these lower levels are inversely correlated with both the components of MetS and noninvasive fibrosis scores. MAFLD negatively correlated to the MetS components and noninvasive scores of fibrosis. [ABSTRACT FROM AUTHOR]

Early diagnosis and early treatment can prevent joint damage inrheumatoid arthritis (RA); but the lack of appropriate diagnosticcriteria hinders early diagnosis. There are not many disease-specificserological markers for the diagnosis of the disease. Highly sensitiveand specific markers are needed in the early stages of the disease. Theautoantibodies which probably play an importanat role in thepathogenesis of RA and have increasingly been examined in recentyears, will be reviewed, discussed, and examples given of the workdone.

Our study aimed to evaluate and compare the changes in ulnar nerve tension and strain at different elbow positions radiologically and mechanically before and after applying the medial K-wire on the supracondylar humerus fracture cadaver model. We used ten fresh frozen cadaver upper extremity specimens to measure strain and tension on the ulnar nerve in 3 different elbow positions: elbow full extension, elbow flexion-forearm supination, and elbow flexion-forearm pronation. We employed Shear wave elastography (Siemens Acuson S3000 USG, 9L4 linear probe) and a microstrain gauge (Microstrain, Inc., Burlington) to obtain our measurements. Minimum, maximum and mean stress and strain values on the nerve and its surroundings were measured and compared statistically. The mean values of elbows with full extension are statistically lower than those in elbows with 90° flexion-forearm supination and those with 90° flexion-forearm pronation positions. Statistical evaluations were performed between all of the groups. Elbow 90° flexion-forearm pronation, both minimum and maximum and mean values were statistically higher in the group, including the specimens with Kirschner applied. The mean values in the elbow full extension and elbow 90° flexion-forearm supination positions were statistically similar in the specimens with and without the K-wire applied. Despite the numerous techniques described in the literature, there is no absolute technical method to prevent ulnar nerve damage. K-wire application to the medial epicondyle with the elbow in a slightly extended position is a technique that can be applied to reduce the risk of ulnar nerve paralysis. However, it has been reported that ulnar nerve damage can be observed in cases where a splint is placed in the 90° flexion position. We hypothesize that the position of the elbow joint in the postoperative period may contribute to ulnar nerve paralysis due to soft tissue tension and strain and as a result of changing the balance of the surrounding tissues. Our findings suggest that the long arm splint applied in elbow 90° flexion and forearm pronation position should not be preferred in the postoperative period. The maximum strain values obtained in the elbow full extension were lower, suggesting that it would be appropriate to stabilize the elbow in the extension position as much as possible postoperatively.

Background and Objectives : This study was performed for the purpose of assessing whether antiepileptic levetiracetam treatment produces a change in brain volumes in children with epilepsy. To that end, we compared the volumes of the basal ganglia (caudate nucleus, putamen, globus, hip-pocampus, and thalamus) at magnetic resonance imaging (MRI) before and after treatment (months 18-24) in pediatric epilepsy patients using levetiracetam. Materials and Methods : This retrospective study involved a volumetric comparison of patients presenting to the Balikesir University Medical Faculty pediatric neurology clinic between 01.08.2019 and 01.11.2023 and diagnosed with epilepsy, and who underwent cranial MRI before and 18-24 months after treatment at the radiology department. The demographic and clinical characteristics (age, sex, family history of epilepsy, type of epilepsy, and EEG features (normal, abnormal, epileptiform)) of the patients included in the study were recorded. Results: The comparison of basal ganglia volumes at cranial MRI before and at months 18-24 of treatment revealed significant differences in the left caudate nucleus, right putamen, left putamen, left globus pallidus, right thalamus, left thalamus, and right hippocampal regions. Conclusions: In conclusion, differing findings are encountered at cranial imaging in patients with epilepsy, depending on the seizure frequency, activity, and the type of antiepileptic drugs used. This study compared basal ganglia volumes on cranial MRIs taken before and 18-24 months after treatment in pediatric epilepsy patients using levetiracetam. A significant increase was observed in the volumes of basal ganglia (caudate nucleus, putamen, globus pallidus, hippocampus, and thalamus) on the MRIs of pediatric epilepsy patients using levetiracetam.

This study aimed to assess the effect of the status of the tendon and patient factors on patient satisfaction after rotator cuff repair. Forty-six patients treated for tears with a minimum of 5-year follow-up were included. Gender, age, and active smoking status were recorded. Pain visual analogue scale, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, Simple Shoulder Test, and Single Assessment Numeric Evaluation were recorded preoperatively and at the last follow-up. Patients were divided into groups of highly satisfied (HS) and vaguely satisfied (VS) patients. Patients were evaluated with MRI both preoperatively and at their last follow-up. Of the 46 patients, 17 were HS and 29 were VS. The HS group had 7 re-ruptures, 4 of which were progressed tears, whereas the VS group had 15 re-ruptures, 4 of which were progressed tears. There was no difference in the rate of re-ruptures or progressed tears between groups. The HS group had a higher frequency of males. However, frequencies of active smoking or osteoarthritis of grade 2 or higher were lower in the HS group. It was shown that patient satisfaction after repair depends on patient-related factors like gender and smoking rather than tendon healing or degeneration., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Additionally, these lower levels are inversely correlated with both the components of MetS and noninvasive fibrosis scores. MAFLD negatively correlated to the MetS components and noninvasive scores of fibrosis.

Objective: To search whether there is a correlation between middle hepatic venous indices (HVIs) obtained by pulsed waved doppler ultrasonography (PW-DUS) and the main pulmonary artery (mPA) diameter, calculated by computed tomography (CT)., Study Design: A descriptive cross-sectional study., Place and Duration of Study: Department of Radiology, Balikesir University School of Medicine, Turkey, from February to December 2020., Methodology: After excluding the cases with suspected COVID-19 from the cases sent to the Radiology Department for chest CT exams with the mPA included in the cross-sections, the volunteers were evaluated with PW-DUS. The study group consisted of 66 cases. Two radiologists measured the velocity values of the A, S, and D waves in the recorded PW Doppler spectra. HVIs (A/S, A/S+D, A/A+S+D) were calculated. The mPA diameter was calculated in the axial plane from the pulmonary trunk, 1cm proximally to the bifurcation manually on the workstation. The correlation between the HIVs and mPA diameter was evaluated. Interoperator reliability was also analysed., Results: Thirty-nine males (59%) and 27 (41%) females were included in the study group. The mean HVI values were 0.50 ±0.20, 0.28 ±0.12, and 0.21 ±0.07 for A/S, A/A+S, and A/A+S+D, respectively. The mean mPA diameter was 24.0 ±3.3 mm. Correlation analysis determined that the HVIs were positively correlated with mPA diameter (r=0.730-0.765-0.751, p<0.001). Inter-observer correlation coefficients were found to be compatible between two radiologists., Conclusion: A significant and strong correlation was found between HVIs and mPA diameter. The mPA diameter that reflects the pulmonary artery systolic pressure (PAP) increased as the HVIs increased. Therefore, PW-DUS may be helpful to evaluate PAP as a quantitative method that is cost-effective, easily accessible and radiation-free., Key Words: Hepatic veins, Pulmonary artery, Multidetector computed tomography, Pulmonary hypertension, Pulsed doppler ultrasonography.

The present study aims to investigate the effect of amount of lateralization and/or anteversion of the point where the iliac cut meets with the posterior column cut of periacetabular osteotomy (PAO), on X-ray parameters such as Center of edge (CE) angle, retroversion index (RVI) and sharp angle. Fourteen patients with symptomatic hip dysplasia (CE° < 20°) were included. Pelvis Computerized tomography (CT) sections were used for 3D printing. PAO was then performed on these models. The point (A), 1 cm lateral to the pelvic brim, is marked where the iliac cut intersects the posterior column cut. In Group I (1.5-0), point A is lateralized parallel to the osteotomy line for 1.5 cm. In Group II (1.5-0.5), it is additionally anteverted for 0.5 cm. In Group III (3-0), point A is lateralized for 3 cm and then additionally anteverted for 1 cm (Group IV: 3-1). Radiographs were taken in each stage. The lateral CE angle, RVI and sharp angle were measured. All had an increase in the CE angle and RVI and a decrease in the sharp angle compared to the control group ( P  < 0.05). The amount of CE angle (ΔCE) or RVI increase (ΔRV) was as follows: 3-1(38°, 0.3) > 3-0(27°, 0.2) and 1.5-0.5(25°, 0.1) > 1.5-0(17°, 0.07) ( P  < 0.05) (with no difference between groups 1.5-0.5 and 3-0, P  = 0.7). The amount of sharp angle decrease was as follows: 3-1(20°), 3-0(18°) < 1.5-0.5(11°) < 1.5-0(8°) ( P  < 0.05). The lateralization of the intersection point where the iliac wing cut meets with the posterior column cut along the cut surface led to an increase of lateral cover and focal retroversion. Additional anteversion leads to further increases in those parameters, while groups 1.5-0.5 and 3-0 did not differ between., (© The Author(s) 2022. Published by Oxford University Press.)

Introduction: Multidetector Computed Tomography (MDCT) is a widespread method for evaluating paranasal sinuses and nasal cavity in daily practice. The maxillary teeth are in field of view in a paranasal sinus CT scan and it is possible to detect dental pathologies with CT., Aim: To determine the incidence of maxillary teeth pathologies in routine paranasal sinus CT scans., Materials and Methods: A retrospective study was conducted. Consecutive 395 paranasal sinus CT scans were evaluated. All CT images were obtained with a 64 detector-CT. Patients with previous facial trauma, operation, invasive tumors and repeated exams were excluded. Detected findings were classified as "tooth loss, dental restorations or procedures and dental pathologies (carious lesions, dental developmental anomalies, periapical lesions and periodontal diseases). The proportion of findings was reported as simple percentiles., Results: Three hundred and eighty-four CT scans were included in the study. Dental restorations or procedures were determined in 129 (33.5%) patients. A total of 34 (8.8%) patients had normal teeth count and morphology. A total of 264 (64.3%) patients had at least one tooth loss. A total of 195 (51%) patients had at least one or more dental pathology. Number of dental carious lesions, dental developmental anomalies, periapical lesions and periodontal disease were 104 (27.0%), 78 (14.3%), 46 (11.9%), 44 (11.4%), respectively., Conclusion: Dental pathologies were encountered in more than half of the patients. Detecting dental pathologies may prevent tooth loss and improve oral health. The radiologist should keep in mind dental pathologies while evaluating paranasal sinus CT in daily practice.

Objective: The bony nasolacrimal duct (BNLD) morphology as a contributory factor in primary acquired nasolacrimal duct obstruction (PANDO) is still controversial. The objectives of this study were to evaluate the morphometric differences of BNLDs in unilateral PANDO patients between PANDO and non-PANDO sides, as compared with the control group using multidetector computed tomography (CT)., Materials and Methods: Bilateral BNLDs in 39 unilateral PANDO patients and 36 control subjects were retrospectively reviewed. CT images with 0.5-mm thickness were obtained with a 64-slice scanner. The length, volume, coronal orientation type, sagittal orientation angle of BNLD, and relative lacrimal sac-BNLD angle were assessed. The entrance, minimum and distal end transverse diameters (TD) of BNLD was investigated., Results: The mean minimum and distal end BNLD TDs measurements were significantly narrower in PANDO patients, both in PANDO and non-PANDO sides, as compared with the control group (p < 0.001 and p = 0.040, respectively); however, there were no significant differences between PANDO and non-PANDO sides within PANDO patients. The length, entrance TD, volume, coronal orientation type, sagittal orientation angle of BNLD, and relative lacrimal sac-BNLD angle were not significantly different between PANDO patients and control subjects, as well as between PANDO and non-PANDO sides within PANDO patients., Conclusion: The narrow mean minimum and distal end BNLD TD in PANDO patients, in both PANDO and non-PANDO sides, may be associated with PANDO development. The lack of difference between PANDO and non-PANDO sides within PANDO patients and some overlap between PANDO patients and control subjects suggest that narrow BNLD is not the sole factor.

Introduction: Computed tomography (CT) is a widespread method for evaluating head and neck pathologies. The lacrimal glands (LGs) are usually visible in routine head and neck CT scans. LG pathologies usually manifests with changes in gland sizes, so it is important to know the normal values of the LG dimensions and volume. The LG sizes may change with age, gender and race. The normal values of LG dimensions and volume in Turkish population was not reported before., Aim: The aim of this study was to evaluate the dimensions and volumes of the LGs by CT in a Turkish population., Materials and Methods: Two hundred seventeen consecutive paranasal CT scans of subjects evaluated retrospectively. Measurements of LG dimensions were performed in axial and coronal paranasal CT images. The LG volume was calculated with Aquarius software by outlining the gland in all consecutive axial images., Results: Four hundred orbits of 200 subjects were included to the study. The mean axial LG length in right and left orbits were 16.2±2.0 mm and 16.0±2.0 mm and the mean axial width of the right and left orbits were 4.1±0.7 mm and 4.0±0.7 mm. The right and left LG mean values for coronal length and width were equal 18.3 ±2.2 mm and 4.1±0.7mm respectively. The mean LG volume was 0.617±0.210 cm(3) in right and 0.597±0.197 cm(3) in the left orbits. There were statistically significant differences in the axial width and volume of the LG according to sides, however there was no significant difference according to gender. Age and LG measurements were negatively correlated., Conclusion: Our study may serve as a guide to determine the average values of the LG measurements in Turkish population and find out the orbital pathologies that involves the LG.

An extraordinary cerebral venous drainage pathway and dilated vein at the left posterior cervical region were detected with routine contrast-enhanced neck computed tomography exam. The left sigmoid sinus was drained by dilated mastoid emissary vein (MEV). The MEV continued as posterior auricular and posterior external jugular veins (PEJVs). The left PEJV directly drained into subclavian vein. Atretic right transverse sinus, left facial vein forming the external jugular vein, atresia and hypoplasia of upper internal jugular veins at the right and left sides, respectively, were the other uncommon findings in our case. Detecting venous variations may prevent complications during surgical and interventional procedures, so the radiologists should examine the superficial cervical veins closely.

Liposarcoma (LPS) of vulva is a rare entity. We present the ultrasonographic (US) and color Doppler ultrasonographic (CDUS) findings of a vulvar myxoid LPS. Although LPS cases have been reported in the extremities and trunk, the US or CDUS findings of LPS in vulva have not been described previously. On US the mass appeared as a well-defined, homogeneous hypoechoic structure and on CDUS it was quite hypervascular.

Purpose: To investigate whether there is an association between primary acquired nasolacrimal duct obstruction and paranasal computed tomography (CT) findings., Materials and Methods: The study cohort consisted of paranasal CT images from 40 patients being treated for unilateral primary nasolacrimal duct obstruction (PANDO) and the reformatted coronal temporal CT images of 71 control subjects who attended the ENT clinic with the complaint of vertigo and tinnitus. A radiologist masked to the clinical situation of participants, investigated the paranasal CT findings of the PANDO and control patients retrospectively. The side, localization, and angle of the septal deviation as well as the thickness and lateralization angle of the inferior turbinate's were recorded. Additionally maxillary and ethmoid sinusitis, concha bullosa, Agger nasi cell formation, and osteomeatal complex status were evaluated., Results: No significant difference was found between the paranasal abnormality incidence in the PANDO and non-PANDO sides of the patients or the control group. Only the side of the septal deviation correlated with the side of the PANDO (p = 0.008)., Conclusions: The incidence of PANDO may not be directly related to paranasal abnormalities. Further large-scale studies should be performed to clarify the relationship between paranasal abnormalities and PANDO.

Purpose: To investigate whether unilateral primary acquired nasolacrimal duct obstruction (PANDO) causes Schirmer score and lacrimal gland volume changes in the contralateral non-PANDO eye., Methods: Sixteen unilateral female PANDO and 16 female controls were enrolled in the study. Exclusion criteria were orbital trauma, inflammation, infection, tumor involvement or infiltrative diseases, history of ocular surgery, ocular surface disorder, systemic drug use that interferes with tear secretion, and chronic use of topical eye drops. Bilateral lacrimal gland volumes were measured in computed tomography (CT) images of the participants. A Schirmer test without anesthesia was also performed on each participant., Results: As there was no significant difference between the right and left eye values for Schirmer and gland size (P > 0.05), both eyes of the control group were enrolled in the study. The groups were age matched and the mean lacrimal gland was 0.479 cm3 in the PANDO as well as the contralateral non-PANDO side, which was statistically smaller compared to the control eyes (0.580 cm3) (P = 0.04). The mean Schirmer scores in the same order were 18.5 ± 7.1 mm, 13.2 ± 8.9 mm, and 21.3 ± 10.5 mm, respectively. Non-PANDO side Schirmer scores were lower compared to the other two groups, but statistical significance was present for the control group (P = 0.04)., Conclusions: Compared to the control group, lacrimal gland volumes were bilaterally smaller in unilateral PANDO patients. Schirmer scores were statistically lower in the contralateral non-PANDO side compared to the controls.

Objective: We aimed to investigate the relationship between allergic rhinitis, which is an important reason of nasal obstruction, and maxillary sinus aeration., Patients and Methods: Three hundred fifteen patients who have a complaint of nasal obstruction and scheduled to undergo skin prick test (SPT) with a suspicion of allergic rhinitis (AR) were enrolled for this study. Thirty-two patients with positive SPT result and 30 patients with a negative SPT result were determined as group 1 and 2 (control group), respectively. A 3-dimensional reconstruction of computed tomography images of the 62 patients was used to assess and calculate maxillary sinus volumes (MSVs)., Results: Total maxillary sinus volumes were measured as 21.87 cm(3) and 30.15 cm(3) in group 1 and group 2, respectively. A statistically significant difference was observed between the MSVs of the groups (P < 0.001)., Conclusion: Total maxillary sinus volumes were found to be significantly smaller for patients with a positive SPT compared to patients with a negative SPT. Thus, we may conclude that AR has a negative impact on maxillary sinus aeration.

Objective: To date the anatomy of the popliteal artery variations using multidetector-row computed tomography angiography (MD CTA) was not assessed. The objective of this study is to establish 3D CT anatomy of the popliteal artery variations., Materials and Methods: A total of 126 lower limbs that underwent CTA using 64-detector MDCT were retrospectively reviewed. The anatomical variations of the distal popliteal artery branching were assessed., Results: Ninety-seven lower limbs (83.6%) had the usual branching pattern (type 1 A) with tibialis anterior artery (TA) arising first followed by the tibial-peroneal trunk, which then gives rise to the tibialis posterior artery (TP) and peroneal artery. Variations in popliteal branching pattern were seen in 19 (16.4%) limbs. The commonest variation was first branch of the TP in 5 (4.4%) of the limbs (type 1 C) or high origin with anterior course of popliteus muscle of the TA in 5 (4.4%) limbs (type 2 A II)., Conclusion: Many variations exist in the running patterns of the branching pattern of the popliteal artery. Knowledge of the branching pattern of the popliteal artery will be beneficial to radiologist for the evaluation of CT angiograms and interventional vascular procedures, and to vascular surgeons for various surgical approaches. MD CTA provides noninvasive means of assessing distal popliteal artery variations.

Objective: To evaluate and compare the fatty degeneration of multifidus muscles by chemical shift magnetic resonance imaging (MRI) in patients with chronic low back pain and in asymptomatic volunteers., Materials and Methods: Sixty-five patients with lumbar disc pathology were selected prospectively for this study. The control group consisted of 25 asymptomatic volunteers. The patients were grouped according to the fatty degeneration of multifidus muscles by a semiquantitative method (grade 0-4) on axial T2 weighted imaging. Chemical shift MRI was performed in the axial plane using a double-echo fast low-angle shot (FLASH) sequence. Fatty degeneration was calculated through signal intensity suppression rate (SISR) and signal intensity index (SII)., Results: The semiquantitative grading of fatty degeneration of the multifidus muscle was 0 in 25 of 65 patients (patient group 0), 1 in 20 patients (patient group 1), 2 in 20 patients (patient group 2). Neither grade 3 nor grade 4 were detected in patient groups. For the control group, patient group 0, patient group 1, and patient group 2, median SISR values were 5.00, -9.00, -17.50, and -22.50 %, respectively. SII median values were -4.20 % for the control group, 7.00 % for patient group 0, 12.50 % for patient group 1, and 19.50 % for patient group 2. SISR values in the multifidus muscle calculated for the patient groups were significantly lower than those calculated for the control group. SII values in patients groups were significantly higher than in the control group., Conclusions: Chemical shift MRI may be a useful method to quantitatively evaluate the fatty degeneration in multifidus muscle in patients with low back pain.

Polyneuropathy, organomegaly, endocrinopathy, M protein and skin changes (POEMS) syndrome is a rare multi-system disease. We describe the ultrasonography (US) and color Doppler ultrasonography (CDUS) findings of peripheral neuropathy in a patient with POEMS syndrome. In US examination, peripheral nerves were found to be diffusely thickned in both upper limbs. CDUS imaging showed arterial blood flow with low systolic peaks on the nerves., (Copyright © 2011 Wiley Periodicals, Inc.)

Objectives: To adapt the London Handicap Scale into the Turkish language, and to investigate the scaling properties of this version in a sample of people who have experienced a stroke., Design: After the translation process, the internal construct validity was tested by Rasch analysis and the reliability by internal consistency and intraclass correlation coefficient. The interval scaling properties were assessed by contrasting the raw and weighted London Handicap Scale scores with the Rasch latent estimates., Setting: An outpatient rehabilitation unit of a university hospital., Subjects: One hundred and eighty-eight community-dwelling post-stroke patients (mean age 63 (SD 12) years, 54% male) were assessed by the Turkish version of the London Handicap Scale., Results: After adjustment for local dependency, the data showed good fit to Rasch model expectations with a mean item fit -0.240 (SD 1.868), person fit -0.403 (SD 0.893) and chi-square interaction 8.55 (df 10, P = 0.575). The reliability was good with a Cronbach's α and intraclass correlation coefficient of 0.845. Analysis of the scaling properties showed that either the raw London Handicap Scale score or its weighted score were non-linear with respect to the Rasch latent estimate., Conclusions: The London Handicap Scale is a valid and reliable scale for use in stroke in Turkey. Its unweighted raw scores and weighted scores are equivalent and ordinal, but a linear transformation is possible through Rasch analysis.

Carotid blowout syndrome (CBS) is a rare but well-known complication of aggressive radiotherapy management of head and neck cancer. Reports on magnetic resonance imaging (MRI) findings of CBS are limited in the relevant literature, probably because of the angiography priority of this complication. We describe MRI findings in a patient with nasopharyngeal carcinoma complicated with CBS.

Splenogonadal fusion is a rare congenital anomaly in which the spleen is abnormally connected to the gonad. Two types of splenogonadal fusion have been described: continuous and discontinuous. Splenogonadal fusion is frequently associated with cryptorchidism and/or congenital orofacial/limb anomalies. We describe the ultrasound findings in a case of continuous-type splenogonadal fusion associated with ipsilateral testicular atrophy with correlation with MRI., (Copyright 2009 Wiley Periodicals, Inc.)

Laryngocele is an uncommon disease defined as an abnormal dilatation or herniation of the laryngeal saccule, forming an air-filled cavity. Radiologic evaluation of a suspected laryngocele generally includes plain radiographs, CT, and MRI. There are very few reports in the literature on sonographic findings of laryngocele. Trumpet maneuver has been reported in CT examination for the diagnosis of laryngocele. However, to the best of our knowledge, the use of trumpet maneuver in the sonographic diagnosis of laryngocele has not been previously described. This report presents the sonographic findings of an external laryngocele while performing the trumpet maneuver., ((c) 2009 Wiley Periodicals, Inc. J Clin Ultrasound, 2010.)

Objectives: We aimed to investigate the glomerular hyperfiltration due to pregnancy in women with more parities., Methods: Five hundred women aged 52.57 +/- 8.08 years, without a history of hypertension, diabetes mellitus or complicated pregnancy were involved in the study. They were divided into three groups. Group 1: women with no or one parity (n = 76); group 2: women with two or three parities (n = 333); group 3: women with four or more parities (n = 91). Laboratory parameters and demographical data were compared between the three groups., Results: Mean age, serum urea and serum creatinine were similar between three groups. Patients in group 3 had significantly higher GFR values compared to groups 1 and 2 (109.44 +/- 30.99, 110.76 +/- 30.22 and 121.92 +/- 34.73 mL/min/1.73 m(2) for groups 1, 2 and 3, respectively; P = 0.008 for group 1 vs group 3; P = 0.002 for group 2 vs group 3)., Conclusions: In our study, we suggest that glomerular hyperfiltration due to pregnancy does not have adverse effects on kidney in women with more parities. Pregnancy may have possible protective mechanisms for kidney against adverse effects of glomerular hyperfiltration.

Scapular mobility plays a central role in normal shoulder function, and alterations in scapular mobility have been suggested as a factor in impingement syndrome. We therefore measured the effect of restricted scapular mobility during arm abduction on acromiohumeral and coracohumeral distances. For the control measurements, healthy volunteers (n = 10, all male, age range 25-35 years) underwent multislice computed tomography in a supine position, with the humerus actively maintained in the scapular plane at 45 degrees internal rotation and 60, 90 or 120 degrees abduction. To restrict scapular mobility a custom-made brace was then placed on each volunteer and fastened firmly with bandages, and the measurements were repeated. From the three-dimensional images the acromiohumeral and coracohumeral distances were measured. With the humerus in 90 degrees abduction, the acromiohumeral distance was significantly reduced (Student's t test). This result suggests that impingement syndrome may have a functional component.
