The current study documents an unusual case of iris metastasis as the first sign of small cell lung cancer (SCLC) and reviews the relevant literature to increase understanding and awareness of this rare condition. A 59-year-old male chronic smoker presented with a painful and red right eye without any disturbance of vision. The patient also complained of associated chronic cough and anorexia. Upon examination, an exfoliative, pinkish-white lesion of the right iris was observed. A systemic work-up was performed, which incidentally detected metastatic SCLC in the lower lobe of the right lung and was confirmed by histopathological examination...

Phase change agents consisting of low boiling point perfluorocarbon (PFC) compounds have attracted increasing attention for ultrasound contrast-enhanced imaging and tumor therapy. However, the refraction, acoustic shadowing, reverberation, or limited penetration depth hamper their practical applications through previously reported acoustic droplet vaporization (ADV) or optical droplet vaporization (ODV) technique. Herein, we demonstrate a magnetic droplet vaporization (MDV) approach by loading perflurohexane (PFH) in magnetic mesoporous particles with a hollow space to carry out ultrasound imaging and tumor ablation...

Human mesenchymal stem cells (hMSCs) have great potential for cell-based therapies for treating degenerative bone diseases. It is known that mechanical cues in the cell microenvironment play an important role in regulating osteogenic (bone) differentiation of hMSCs. However, mechanoregulation of lineage commitment of hMSCs in conventional two-dimensional (2D) monocultures or bioengineered three-dimensional (3D) tissue constructs remains suboptimal due to complex biomaterial design criteria for hMSC culture...

PURPOSE: Delayed onset muscle soreness (DOMS) occur within 1-2 days after eccentric exercise but the mechanism mediating hypersensitivity is unclear. This study hypothesized that eccentric exercise reduces the blood flow response following muscle contractions and cuff occlusion, which may result in accumulated algesic substances being a part of the sensitization in DOMS. METHODS: Twelve healthy subjects (5 women) performed dorsiflexion exercise (5 sets of 10 repeated eccentric contractions) in one leg, while the contralateral leg was the control...

Benign intraperitoneal metastatic leiomyomatosis is a rare benign disease that is observed when a leiomyoma is present in the peritoneal surface. Women who have undergone hysterectomy for leiomyomas are most commonly affected. Patients are usually asymptomatic at presentation, being frequently an incidental finding in imaging studies. Ultrasound and CT play an important role in the diagnosis. The lesions are histologically identical to their uterine counterparts. There are different theories about the pathogenesis of the disease, including peritoneal seeding after laparoscopic hysterectomy...

INTRODUCTION: Pseudoamniotic band syndrome (PABS) occurs iatrogenically after fetal surgery or amniocentesis due to chorioamniotic membrane separation. Separation of the amnion from the chorion can expand to form fibrous amniotic bands that can envelope fetal limbs or the umbilical cord, with consequences ranging from limb constriction to fetal demise. CASE REPORT: We report a case of bilateral fetal pleural effusions at 27 weeks' gestation treated by bilateral thoracoamniotic shunts...

BACKGROUND: In 1962, Bertil Stener first described the anatomy and treatment of the displaced ulnar collateral ligament of the metacarpophalangeal joint, later called the Stener lesion. Since Stener's publication, treatment algorithms for ulnar collateral ligament rupture have aided in preoperative diagnosis, yet the best diagnostic method to assess ligament displacement remains largely undefined. METHODS: An extensive literature search was performed to explore the treatment evolution of the Stener lesion and explore how technical development has influenced Stener lesion diagnosis...

BACKGROUND: Skeletal muscle injuries are the most common sports-related injury and a major concern in sports medicine. The effect of platelet-rich plasma (PRP) injections on muscle healing is still poorly understood, and current data are inconclusive. PURPOSE: To evaluate the effects of an ultrasound-guided intramuscular PRP injection, administered 24 hours after injury, and/or posttraumatic daily exercise training for 2 weeks on skeletal muscle healing in a recently established rat model of skeletal muscle injury that highly mimics the muscle trauma seen in human athletes...

BACKGROUND: Quantitative sonographic methods are used to assess pleural fluid's volume but no validated method exists for the measurement of the fluids' density and other qualitative values. We suggest a quantitative method, based on the pixel density of the pleural effusion's image, in order to evaluate the echogenicity of pleural effusion. METHODS: Pleural ultrasound (US) was performed in 62 patients with pleural effusion. Five consequent images of the pleural effusion were retrieved through axial view between the 9(th) and the 10(th) rib and one from the 10(th) rib through coronal view and converted into the high-resolution tagged image file format...

Although lymphoepithelial cysts (LECs) of the pancreas are benign lesions, most of them have been treated with surgical resection due to diagnostic difficulty. We report a 66-year-old woman diagnosed with pancreatic LECs. Abdominal ultrasound revealed two masses in the pancreas, which were not visible on the abdominal computed tomography. In an abdominal magnetic resonance imaging, pancreas lesions showed solid tumors, which revealed a low signal intensity on T1-, moderate high signal intensity on T2 weighted images, and homogeneous delayed enhancement in the portal venous phase...

INTRODUCTION: To ascertain whether combined ultrasound assessment of fetal head circumference (HC) and maternal subpubic angle (SPA) prior to the onset of labour may predict the likelihood of an unplanned operative delivery (UOD) in nulliparous women at term. MATERIAL AND METHODS: Prospective cohort study of singleton pregnancies in cephalic presentation. Pregnancies experiencing UOD secondary to fetal distress were excluded. HC was assessed transabdominally while SPA values were obtained from a reconstructed coronal plane on three-dimensional(3D) ultrasound performed trans-labially at 36-38 weeks of gestation...

Background: Changes in cerebral blood flow velocity (CBF) in response to a cognitive task (task-related ΔCBF) have been shown by Transcranial Doppler ultrasonography (TCD) to be reduced in slow walkers. However, it is unknown whether reduced task-related ΔCBF is associated with reduced neural activity in specific brain regions, as measured by blood-oxygen-level dependent (BOLD) functional magnetic resonance imaging (fMRI). Methods: We assessed the regional changes in neural activity associated with reduced middle cerebral artery (MCA) task-related ΔCBF to an executive task and slow walking speed in 67 community-dwelling older adults from the MOBILIZE Boston Study...
