Most studies of the mechanisms leading to hereditary dilated cardiomyopathy (DCM) have been performed in reconstituted in vitro systems. Genetically engineered murine models offer the opportunity to dissect these mechanisms in vivo. We generated a gene-targeted knock-in murine model of the autosomal dominant Arg141Trp (R141W) mutation in Tnnt2, which was first described in a human family with DCM. Mice heterozygous for the mutation (Tnnt2R141W/+) recapitulated the human phenotype, developing left ventricular dilation and reduced contractility...

Chronic refractory angina is often a disabling condition, predominantly due to severe obstructive coronary artery disease, that is inadequately controlled by optimal medical therapy and not amenable to further percutaneous or surgical revascularization. Mortality rates associated with this condition are relatively low in clinically stable patients. However, it is associated with a high hospitalization rate and a reduction in both exercise capacity and quality of life. Due to the paucity of available treatment options, there is an unmet need for new therapies for these patients and for a reduction in the associated economic healthcare burden...

BACKGROUND: Bitter taste receptors (T2Rs), especially T2R38s appear as innovative regulators of innate immunity in the respiratory system. The single nucleotide polymorphisms (SNPs) in TAS2R38 gene may contribute to individual differences in susceptibility to respiratory infections especially chronic rhinosinusitis (CRS). TAS2R38 genotypes distribution varies by geographic region, race and ethnicity. The aim of the preliminary study was the identification of SNPs in TAS2R38 encoding genes in Polish patients with CRS and finding potential correlation with CRS phenotypes...

BACKGROUND: Some patients undergoing dural sinus stenting for idiopathic intracranial hypertension (IIH) develop clinical and hemodynamic failure (recurrence of the pressure gradient) owing to stent-adjacent stenosis. OBJECTIVE: To characterize factors associated with hemodynamic failure, and to describe outcomes of patients after repeat stenting. MATERIALS AND METHODS: We reviewed the initial and follow-up clinical, venographic, and hemodynamic data in 39 patients with IIH treated over 17 years with stenting...

Interdural dermoid cysts (DCs) of the cavernous sinus (CS), located between the outer (dural) and inner layer (membranous) of the CS lateral wall, are rare lesions in children. The authors report on a 5-year-old boy with third cranial nerve palsy and exophthalmos who underwent gross-total removal of an interdural DC of the right CS via a frontotemporal approach. The patient had a good outcome and no recurrence at the 12-month follow-up. To the best of the authors' knowledge this is the second pediatric case of interdural DC described in the literature...

Sunitinib is a multiple tyrosine kinase inhibitor with antiangiogenic, cytostatic, and antimigratory activity for meningiomas. A recent clinical trial of sunitinib for treatment of recurrent Grade II and III meningiomas suggested potential efficacy in this population, but only 2 patients exhibited significant radiographic response with tumor volume reduction. The authors illustrate another such case and discuss a complication related to this dramatic tumor volume reduction in aggressive skull base meningiomas...

PURPOSE: Transanal minimally invasive surgery using single port instrumentation is now well described for the performance of total mesorectal excision with restorative colorectal/anal anastomosis most-often in conjunction with transabdominal multiport assistance. While non-restorative abdomino-endoscopic perineal excision of the anorectum is conceptually similar, it has been less detailed in the literature. METHODS: Consecutive patients undergoing non-restorative ano-proctectomy including a transperineal endoscopic component were analysed...

A 23-year-old male with intermittent visual loss in his left eye for 4 months was originally treated as optic neuritis elsewhere. Upon presentation to our hospital (Beijing Tongren Hospital), his left eye visual acuity was reduced to hand motion at face. The left eye ocular motility was limited in upgaze, downgaze, adduction, and abduction. Computed tomography and magnetic resonance imaging revealed lesions in the sphenoid and ethmoid sinuses, orbital apex and carvernous sinus invading adjacent extraocular muscles...

PURPOSE: Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. PATIENTS AND METHODS: We retrospectively reviewed 11 patients treated with one-stage orbital and sinus surgery...

BACKGROUND Extranodal lymphoma of the paranasal sinuses is a rare clinical entity seen in only 5-8% of extranodal lymphomas of the head and neck. Nasal natural killer/T cell lymphoma (Nasal NKTCL), which is a subtype of peripheral T cell lymphoma, constitutes about 1.4% of all lymphomas. NKTCL is usually diagnosed at a late stage because it presents with nonspecific symptoms in the early stages. CASE REPORT We report the case of a 25-year-old male patient who presented with periorbital swelling treated as fungal sinusitis but proven to have NKTCL...

BACKGROUND AND PURPOSE: Resistance to blood flow in the cerebral drainage system may affect cerebral hemodynamics. The objective of the present study was to use phase-contrast MRA to quantify resistance to drainage of blood across branches of the venous sinus tree and to determine whether the resistance to drainage values correlated with internal jugular vein outflows. MATERIALS AND METHODS: We performed whole-head phase-contrast MRA and 2D phase-contrast MR imaging in 31 healthy volunteers...

Invasive aspergillosis (IA) is diagnosed almost exclusively in immunocompromised patients. It is located mainly in the lungs or paranasal sinuses, but occasionally other organs and the gastrointestinal tract may also be affected either alone or as a part of a disseminated disease. The main risk factors predisposing to IA are neutropenia, immunosuppressive and steroid therapy, as well as severe underlying disease. Despite progress in diagnostics and therapy of IA, it is still characterized by a high mortality rate...

BACKGROUND: Spindle cell lipoma is an uncommon variant of lipoma and usually occurs as a solitary, subcutaneous, and well circumscribed lesion in the posterior neck, shoulders, and back of older men. Primary renal lipomas are rarely reported. Spindle cell lipoma in the kidney has not been previously described in the literature. CASE REPORT: A 60-year-old Chinese man suffered graft failure 10 years after living related donor kidney transplantation. During cancer surveillance, he was found to have a mass in the renal allograft, which increased in size and was suspicious for renal cell carcinoma on computerized tomographic scan...

INTRODUCTION: Endoscopic sinus surgery is a minimally invasive procedure used to restore normal sinus ventilation and mucociliary function. It is a routine otolaryngology procedure with a success rate of about 90% for symptomatic improvement in patients with refractory chronic rhinosinusitis. Because of the proximity of the paranasal sinuses to the brain and the orbit, it cannot be performed without a potential risk of complications. In our case, without early clinical suspicion, proper diagnosis and management, this unusual occurrence of pneumomediastinum after endoscopic sinus surgery may have led to major complications or even death...
