Surgical re-implantation of the left coronary artery (LCA) is the treatment of choice in anomalous origin of left coronary artery from pulmonary artery (ALCAPA). Despite normalization of left ventricular function after surgery, residual coronary lesions or myocardial fibrosis may be found. The aim of this study was to detect regional left ventricular dysfunction predictive of coronary lesions or residual myocardial fibrosis using speckle tracking. We enrolled ten patients treated with surgical re-implantation of LCA for ALCAPA...

Chronic traumatic encephalopathy (CTE) is a progressive degenerative disorder associated with repetitive traumatic brain injury. One of the primary defining neuropathological lesions in CTE, based on the first consensus conference, is the accumulation of hyperphosphorylated tau in gray matter sulcal depths. Post-mortem CTE studies have also reported myelin loss, axonal injury and white matter degeneration. Currently, the diagnosis of CTE is restricted to post-mortem neuropathological analysis. We hypothesized that high spatial resolution advanced diffusion MRI might be useful for detecting white matter microstructural changes directly adjacent to gray matter tau pathology...

We investigated the effects of S-777469 (1-[[6-Ethyl-1-[4-fluorobenzyl]-5-methyl-2-oxo-1, 2-dihydropyridine-3-carbonyl]amino]-cyclohexanecarboxylic acid), a novel cannabinoid type 2 receptor (CB2) agonist, on 1-fluoro-2,4-dinitrobenzene (DNFB)-induced ear inflammation and mite antigen-induced dermatitis in mice. The oral administration of S-777469 significantly suppressed DNFB-induced ear swelling in a dose-dependent manner. In addition, S-777469 significantly alleviated mite antigen-induced atopic dermatitis-like skin lesions in NC/Nga mice...

BACKGROUND: The skeleton is the most common site of colonization by metastatic cancers. Zoledronic acid (ZA) has been shown to be effective for the treatment of bone metastases regardless of whether the bone lesions are osteolytic or osteoblastic. Biochemical markers of bone turnover may be useful tools to quantify the degree of bone remodeling in the presence of bone metastases. The aim of this work was to establish the correlation between tumor dispersion (bioluminescence) and biochemical markers of bone turnover in two osteolytic and osteoblastic metastasis models in mice...

BACKGROUND: Recent phase II and III clinical trials demonstrated anti-tumour activity of eribulin, a tubulin-interacting cytotoxic agent, in patients with metastatic soft tissue sarcoma (STS). In this exploratory study, we aimed to identify putative microRNA biomarkers that associate with eribulin sensitivity or resistance in STS. MATERIALS AND METHODS: Archival tumour tissue from primary tumours or metastatic lesions was collected prior to eribulin treatment, from 65 consenting patients involved in the EORTC trial 62052...

OBJECTIVE: While carotid artery stenting (CAS) has been gaining popularity as an alternative to carotid endarterectomy (CEA), the perioperative stroke rate following contemporary CAS remains significantly higher than that in CEA. The purpose of this study was to assess perioperative (within 30-day) therapeutic results in patients with carotid stenosis (CS) after the introduction of preoperative carotid magnetic resonance plaque evaluation in a single center offering both CEA and CAS. METHODS: Based on prospectively collected data for patients with CS who were scheduled for carotid revascularization, retrospective analysis was conducted of 295 consecutive CS patients...

BACKGROUND: Cavernous hemangiomas account for 5-13% of central nervous system vascular lesions. They are usually found intra-axially but rarely involve extra-axial structures, most commonly the middle cranial fossa. A cavernous hemangioma presenting as a clinoid meningioma is extremely rare. CASE DESCRIPTION: We present a 36-year-old male with an asymptomatic intracranial mass found incidentally after an ATV accident. Preoperative MRI revealed a well-defined dural-based lesion arising from the right anterior clinoid process which was nearly homogenously enhancing, with a radiological diagnosis of meningioma...

Toxoplasma gondii infection is an important cause of infectious ocular disease. The physiopathology of retinochoroidal lesions associated with this infection is not completely understood. The present study was undertaken to investigate cytokine production by T cells from individuals with active toxoplasmic retinochoroiditis (TR) comparing with controls. Eighteen patients with active TR and 15 healthy controls (6 controls IgG(+) to Toxoplasma and 9 negative controls) were included in the study. Peripheral blood mononuclear cells were incubated in the presence or absence of T...

Interatrial block (IAB) represents delay or block of conduction between the atria. IAB has been shown to predict the development or recurrence of atrial fibrillation (AF) in various clinical scenarios. Few studies have examined the correlation between coronary artery disease and the prevalence of IAB and its impact on AF. The aim of this study was to determine if specific coronary artery lesions (location and number) are associated with the presence of IAB and development of new-onset AF. Retrospective analysis of patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI) to our institution...

OBJECTIVE: Inferior vena cava (IVC) surgery is uncommon and has traditionally been performed through open surgical approaches. Renal cell carcinoma with IVC extension generally requires vena cavotomy and reconstruction. Open removal of malpositioned IVC filters (IVCF) is occasionally required after endovascular retrieval attempts have failed. As our experience with robotic surgery has advanced, we have applied this technology to surgery of the IVC. We reviewed our institution's experience with robotic surgical procedures involving the IVC to determine its safety and efficacy...

Lateral ankle instability is a common entity that can result in degenerative arthritis if left untreated. Acute ligament injuries should primarily be treated nonoperatively with a course of physical therapy and functional bracing. Chronic ankle instability is defined as mechanical or functional and can be diagnosed using a combination of history, physical examination, stress radiographs, and magnetic resonance imaging. After failure of nonoperative treatment, surgical treatment with anatomic ligament repair and inferior extensor retinaculum augmentation has the best clinical outcomes...

Articular cartilage is a specialized tissue that lines the surface of joints. Injuries to articular cartilage pose challenges due to poor healing potential. Focal cartilage defects are typically the result of high impact or repetitive loads to the articular surface. They tend to occur in the younger, active population and have been shown to cause swelling, pain, and joint dysfunction. Although the natural history of these lesions has never been definitively elucidated in the literature, clinical experience suggests that if left untreated, these lesions will demonstrate an inability to heal and may lead to prolonged increased articular peak stresses, which in turn may lead to pain and significant limitations in the future...

The molecular and cellular mechanisms underlying plaque destabilization remain obscure. We sought to elucidate the correlation between NO, H2S and CO-generating enzymes, nitro-oxidative stress and plaque stability in carotid arteries. Carotid atherosclerotic plaques were collected from 62 patients who had undergone endarterectomy due to internal artery stenosis. Following histological evaluation the plaques were divided into stable and unstable ones. To investigate the impact of simvastatin we divided patients with stable plaques, into those receiving and to those not receiving simvastatin...

BACKGROUND AND AIMS: Disruption of atherosclerotic plaque and distal embolism often cause peri-procedural myocardial injury during percutaneous coronary intervention (PCI). In the present study, we evaluate the association between the characteristics of the target lesion and the amount of debris captured by the filter-type distal protection device. METHODS: We enrolled 120 consecutive patients with acute coronary syndrome, who underwent coronary stent implantation with a filter-type distal protection device after integrated backscatter intravascular ultrasound (IB-IVUS) analysis...

This report investigates the nursing procedure of a case of adjuvant therapy of rectal cancer on IV degree of acute radiation dermatitis patients in the penis and scrotum junction. The lesion degree gradually increased. Fixation of the dressing was difficult in the penis and scrotum junction. The concept of wet healing with new dressings was used in patient. The silver ion dressings were used in inhibiting infection, and the wound was covered by the rimmed foam dressings. When it comes to the shaping period, water gel transparent paste was applied instead to cover the wound...

Traditionally the presence of fat in closed spinal dysraphism has been referred to as spinal lipoma. Recent reports suggest that these spinal lesions are better described as spinal hamartomas due to the unencapsulated and infiltrating nature of the fat and presence of other heterotopic soft tissue. The presence of ossified bone in spinal hamartomas referred to as ossified dysraphic hamartoma, is extremely rare with only three case reports in literature, all associated with lipomyeloceles, none with lipomyelomeningoceles...
