This case is described of an eleven-month-old infant with lower limbs swelling and the left elbow skeletal malformation following a fall. The radionuclide bone scan was performed to exclude bone infection or congenital skeletal anomaly. The images unexpectedly showed multiple increased radioactive foci throughout the whole body. It was a strong probability of child abuse. All lesions are readily apparent on the following plain film radiographs and MRI.

Mri Protocol

The aim of the study is to evaluate the effectiveness of short whole-body magnetic resonance imaging (WBMRI) protocols for the overall assessment of bone marrow involvement in patients with multiple myeloma (MM), in comparison with standard whole-body MRI protocol. Patients with biopsy-proven MM, who underwent a WBMRI with full-body coverage (from vertex to feet) were retrospectively enrolled. WBMRI images were independently evaluated by two expert radiologists, in terms of infiltration patterns (normal, focal, diffuse, and combined), according to location (the whole skeleton was divided into six anatomic districts: skull, spine, sternum and ribs, upper limbs, pelvis and proximal two-thirds of the femur, remaining parts of lower limbs) and lytic lesions number (<5, 5–20, and >20). The majority of patients showed focal and combined infiltration patterns with bone lesions predominantly distributed in the spine and pelvis. As skull and lower limbs are less frequently involved by focal bone lesions, excluding them from the standard MRI protocol allows to obtain a shorter protocol, maintaining a good diagnostic value.

AbstractTranscranial direct current stimulation (tDCS) has been used aiming to boost exercise performance and inconsistent findings have been reported. One possible explanation is related to the limitations of the so-called “conventional” tDCS, which uses large rectangular electrodes, resulting in a diffuse electric field. A new tDCS technique called high-definition tDCS (HD-tDCS) has been recently developed. HD-tDCS uses small ring electrodes and produces improved focality and greater magnitude of its aftereffects. This study tested whether HD-tDCS would improve exercise performance to a greater extent than conventional tDCS. Twelve endurance athletes (29.4 ± 7.3 years; 60.15 ± 5.09 ml kg−1 min−1) were enrolled in this single-center, randomized, crossover, and sham-controlled trial. To test reliability, participants performed two time to exhaustion (TTE) tests (control conditions) on a cycle simulator with 80% of peak power until volitional exhaustion. Next, they randomly received HD-tDCS (2.4 mA), conventional (2.0 mA), or active sham tDCS (2.0 mA) over the motor cortex for 20-min before performing the TTE test. TTE, heart rate (HR), associative thoughts, peripheral (lower limbs), and whole-body ratings of perceived exertion (RPE) were recorded every minute. Outcome measures were reliable. There was no difference in TTE between HD-tDCS (853.1 ± 288.6 s), simulated conventional (827.8 ± 278.7 s), sham (794.3 ± 271.2 s), or control conditions (TTE1 = 751.1 ± 261.6 s or TTE2 = 770.8 ± 250.6 s) [F(1.95; 21.4) = 1.537; P = 0.24; η2p = 0.123]. There was no effect on peripheral or whole-body RPE and associative thoughts (P > 0.05). No serious adverse effect was reported. A single session of neither HD-tDCS nor conventional tDCS changed exercise performance and psychophysiological responses in athletes, suggesting that a ceiling effect may exist.

The current study aims to analyze the relationship of selected kinematic variables to the technique of pull shot in cricket. For the purpose of the study the researcher purposively selected five male inter-university cricket players from lnipe, gwalior of 18 to 24 years., the technique of pull shot in batting performance of each selected subjects was recorded on the basis of certain criteria (point system). It was divided into 2 components; 1. placement of feet and 2. execution (contact) each consist of maximum 10 points. The angles at selected joints were recorded to the nearest degree. The c.g. was measured nearest to the 1/10th of the centimetre. On the basis of sequence photographs obtained from the videography, the scholar developed stick figures from which selected kinematic variables was calculated. The center of gravity of whole body was determined by kinovea software. To find the the relationship of selected kinematic variables to the technique of pull shot in cricket pearson product moment correlation coefficient was used by means of spss software. It was found that, in case of moment execution angle at left shoulder joint and angle at left elbow joint showed significant relationship with performance.

Whole Body Vibrations

The whole-body vibration occurs in many occupational activities, promoting discomfort in the working environment and inducing a variety of psycho – physical changes where consequences as a permanent dysfunction of certain parts of the organism may occur. The main goal of this short systematic review is finding the articles with the most reliable results relating whole-body vibrations to buses and, to compare them with the results of drivers’ lower limbs musculoskeletal disease which occurs as a consequence of many year exposure. PRISMA Statement Methodology was used and thereby 27 Scientific Journals and 25 Index - Database were searched through where 3996 works were found, of which 24 were included in this paper. As a leading standard for analysis of the whole-body vibration the ISO 2631 – 1 is used, while in some papers as an additional standard the ISO 2631-5 is also used for the sake of better understanding the vibrations. Furthermore, the European Directive 2002/44 / EC is included where a daily action exposure to the whole-body vibrations is exactly deter-mined. All the results presented in the paper were compared with the aforesaid standards. After having searched the databases, papers that deal with research of the impact of the vibration on the driver’s lower limbs did not contain any information’s on the described problem.

Abstract Background: Primary central nervous system lymphoma (PCNSL ) is a rare and aggressive malignant tumor. It is easy to be misdiagnosed due to its low incidence and unspecific presentations in clinical practice. PCNSL mainly occurs intracranially in the brain while spinal cord is rarely involved. Case presentation: Here we report a 76-year-old woman who had a suspicious tumor history and presented retardant paralysis, bladder dysfunction and sensory loss of the lower limbs. Magnetic resonance imaging (MRI) of the thoracic spine disclosed longitudinally extensive lesions extending from thoracic 4 (T4) to lumbar 1 (L1) vertebral level with an enhanced nodular lesion noting at levels of T10 and T11 . In order to further identify the cause, the whole body 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography (PET)/computed tomography (CT) was performed and showed a hypermetabolic nodule corresponded to MRI enhancing lesions, which further suggesting the possibility of a tumor. The patient then underwent a surgical resection and spinal cord biopsy confirmed the diagnosis of non-Hodgkin's lymphoma (diffuse large B-cell type). The patient then received a high-dose chemotherapy based on methotrexate combined with Rituximab. Unfortunately, the symptoms of this patient have not been improved significantly after three rounds of chemotherapy. Conclusion: Our case indicates that PCNSL may also serve as a possible cause for longitudinally extensive spinal cord lesions, especially the patients who had a suspicious tumor history, MRI enhancing lesion s in the spinal cord corresponded to hypermetabolic nodules on 18 F-FDG- PET/CT at the same level.

3D Information

In this paper, we introduce an approach for measuring human gait symmetry where the input is a sequence of depth maps of subject walking on a treadmill. Body surface normals are used to describe 3D information of the walking subject in each frame. Two different schemes for embedding the temporal factor into a symmetry index are proposed. Experiments on the whole body, as well as the lower limbs, were also considered to assess the usefulness of upper body information in this task. The potential of our method was demonstrated with a dataset of 97,200 depth maps of nine different walking gaits. An ROC analysis for abnormal gait detection gave the best result ( AUC = 0.958 ) compared with other related studies. The experimental results provided by our method confirm the contribution of upper body in gait analysis as well as the reliability of approximating average gait symmetry index without explicitly considering individual gait cycles for asymmetry detection.
