Neonatal lupus erythematosus is an autoimmune disorder mainly affecting the heart and skin. It is the most common cause of congenital heart block. In addition, hematological, hepatobiliary and neurological involvement may occur. Herein, we report a 23-day-old infant presented with annular, erythematous, and scaly and atrophic lesions on the face and trunk. Based on the clinical, laboratory and histopathological findings, she was diagnosed as neonatal lupus erythematosus. Neonatal lupus eryhtematosus should be considered in infants presenting with annular skin lesions, and we present this case to highlight the value of high index of clinical suspicion in diagnosis...

The pectoral girdle is a complex structure which varies in its morphology between species. A major component in birds is the furcula, which can be considered equivalent to a fusion of the paired clavicles found in many mammals, and the single interclavicle found in many reptiles. These elements are a remnant of the dermal skeleton and the only intramembranous bones in the trunk. Postnatally, the furcula plays important mechanical roles by stabilising the shoulder joint and acting as a mechanical spring during flight...

BACKGROUND: Only a few studies, involving small numbers of patients, have globally assessed the curvature of the thoracic aorta but without any details concerning the location of the supra-aortic trunks. OBJECTIVES: Using CT to describe normal aortic-arch morphology and its changes with age and sex. METHODS: 344 CT scans were studied. We measured the distances from the apex to the ascending and descending aorta, the curvilinear length of the entire arch, that of the segment, including bifurcations of supra-aortic vessels, and the angle, height, and shift of the arch...

PURPOSE: Orthodontists influence dental occlusion directly. To suggest any link between dental occlusion and body posture is highly contentious, as evidenced by the literature. Rasterstereography, an optical technique that enables three-dimensional (3D) body measurements to be collected, has not yet been used to impartially examine whether different occlusal positions could instantaneously alter spine and body posture. We therefore set out to use this technique to nonsubjectively evaluate this question under static conditions...

BACKGROUND AND AIM: The auriculotemporal nerve (ATN) is one of the branches of the mandibular division of the trigeminal nerve, which gives rise to many branches to the retromandibular and temporal regions. Of these, the superficial temporal branch can occasionally be the cause of migraine headaches and auriculotemporal neuralgia. The purpose of this study was to elucidate the anatomy of the superficial temporal branch, which has never been described in detail. METHODS: A total of 14 sides of cadaveric heads were used for this study...

The CIC-DUX4 sarcoma is a subset of the undifferentiated small round cell sarcoma family, presently recognized as a new clinicopathological entity. It is a rare and highly aggressive tumor usually arising in the soft parts of the limbs and the trunk. Only a very few cases of primitive visceral CIC-DUX4 have been hitherto described. We report the case of a 29 year-old male patient with a primary CIC-DUX4 sarcoma of the kidney with lung metastasis. The outcome of the disease was rapidly unfavorable. Despite radical nephrectomy, the patient experienced an early local retroperitoneal recurrence associated with lung and liver metastases...

In the embryo a population of progenitor cells known as the second heart field forms not just parts of the heart but also the jaw muscles of the head. Here we show that it is possible to take skeletal muscle satellite cells from jaw muscles of the adult mouse and to direct their differentiation to become heart muscle cells (cardiomyocytes). This is done by exposing the cells to extracellular factors similar to those which heart progenitors would experience during normal embryonic development. By contrast, cardiac differentiation does not occur at all from satellite cells isolated from trunk and limb muscles, which originate from the somites of the embryo...

The purpose of this study was to validate a commercially available IMU system against a standard lab-based motion capture system for the measurement of shoulder elevation, elbow flexion, trunk flexion/extension and neck flexion/extension kinematics. The validation analyses were applied to six surgical faculty members performing a standard, simulated surgical training task that mimics minimally invasive surgery. Three-dimensional joint kinematics were simultaneously recorded by an optical motion capture system and an IMU system with six sensors placed on the head, chest, and bilateral upper and lower arms...

Virtual environments with real-time feedback can simulate extrinsic goals that mimic real life conditions. The purpose was to compare jump performance and biomechanics with a physical overhead goal (POG) and with a virtual overhead goal (VOG). Fourteen female subjects participated (age: 18.8±1.1 years, height: 163.2±8.1 cm, weight 63.0±7.9 kg). Sagittal plane trunk, hip, and knee biomechanics were calculated during the landing and take-off phases of DVJ with different goal conditions. Repeated measures ANOVAs determined differences between goal conditions...

The inertial measurement unit is popularly used as a wearable and flexible tool for human motion tracking. Sensor-to-body alignment, or anatomical calibration (AC), is fundamental to improve accuracy and reliability. Current AC methods either require extra movements or are limited to specific joints. In this research, the authors propose a novel method to achieve AC from standard motion tests (such as walking, or sit-to-stand), and compare the results with the AC obtained from specially designed movements. The proposed method uses the limited acceleration range on medial-lateral direction, and applies principal component analysis to estimate the sagittal plane, while the vertical direction is estimated from acceleration during quiet stance...

BACKGROUND: Despite having an optimal pull-through operation, some children with Hirschsprung's disease (HSCR) continue to experience persistent bowel symptoms. Coordinated colonic electrical activity depends on intercellular communication between the enteric nerves, interstitial cells of Cajal (ICCs), smooth muscle cells, and fibroblast-like (platelet-derived growth factor receptor-alpha-positive) cells. Gap junctions are low-resistance channels composed of connexin (Cx) proteins which couple cells electrically and chemically...

Motor abundance allows reliability of motor performance despite its variability. The nature of this variability provides important information on the flexibility of control strategies. This feature of control may be affected by low back pain (LPB) and trunk flexion/extension conditions. Goal equivalent manifold (GEM) analysis was used to quantify the ability to exploit motor abundance during repeated trunk flexion/extension in healthy individuals and people with chronic non-specific LBP (CNSLBP). Kinematic data were collected from 22 healthy volunteers and 22 CNSLBP patients during metronomically timed, repeated trunk flexion/extension in three conditions of symmetry, velocity, and loading; each at two levels...

OBJECTIVES: The aim of this study was to investigate whether sonography is a reliable tool for measuring deep abdominal muscle activation in different static arm positions while standing. METHODS: Sonographic recordings were made of the transversus abdominis and obliquus internus abdominis in 4 different static arm positions that varied with regard to the postural demand and loading direction posed on the trunk. Ten nonconsecutive repetitions of each arm position were performed, and thickness measurements were made at 2 locations within each muscle...

BACKGROUND&AIMS: In advanced cirrhosis new hepatocytic nodules are generated by budding of ductules in areas of parenchymal extinction. However, the vascular alterations in the areas of parenchymal extinction, the blood supply and the structure of the new hepatocytic nodules have not been analyzed in detail. METHODS: Explanted human cirrhotic livers of three different etiologies and two experimental models of cirrhosis in rats were examined thoroughly. 3D reconstruction of the immunohistochemically stained serial sections and casting of human and experimental cirrhotic livers have been used to reveal the structural organization of the regenerative buds...
