Hypertophy

BACKGROUND: Disease severity of autosomal dominant polycystic kidney disease (ADPKD) is influenced by diet. Dietary protein, a recognized cyst-accelerating factor, is catabolized into amino acids (AA) and delivered to the kidney leading to renal hypertrophy. Injury-induced hypertrophic signaling in ADPKD results in increased macrophage (MФ) activation and inflammation followed by cyst growth. We hypothesize that the cystogenesis-prompting effects of HP diet are caused by increased delivery of specific AA to the kidney, ultimately stimulating MФs to promote cyst progression...

A particularly prominent mandibular angle or a hypertrophied masseter muscle can result in an excessively wide facial appearance which is often less aesthetically pleasing, especially for women. Though normally a benign condition and strictly an aesthetic concern, a hypertrophied masseter can also cause pain, bruxism, and headaches. Neuromodulator for masseter reduction and treatment of bruxism has become first line. Here we provide the senior author's anatomic approach to neuromodulator injection of the masseter with a corresponding video of the injection technique...

Lysine malonylation, a novel identified protein posttranslational modification (PTM), is conservative and present in both eukaryotic and prokaryotic cells. Previous studies have reported that malonylation plays an important role in inflammation, angiogenesis, and diabetes. However, its potential role in cardiac remodeling remains unknown. Here, we observed a reduced lysine malonylation in hypertrophic mice hearts created by transverse aortic constriction (TAC) for 8 weeks. We also detected a decreased lysine malonylation in hypertrophic H9C2 cardiomyocytes induced by angiotensin II for 48 h...

BACKGROUND: Left ventricular hypertrophy (LVH) is an important risk factor for cardiovascular and all-cause mortality. Previous studies reported conflicting results concerning the relationship between serum lipid levels and left ventricular geometry pattern. We sought to explore the relationship between standard serum lipid profile measures with left ventricular geometry pattern in obese children. PATIENTS AND METHODS: In this cross-sectional study, a total of 70 obese children were examined...

OBJECTIVES: Fibroblast Growth Factor 23 (FGF23) is well documented as a crucial player in the systemic regulation of phosphate homeostasis. Moreover, loss-of-function experiments have revealed that FGF23 also has a phosphate-independent and local impact on skeletogenesis. Here, we used ATDC5 cell line to investigate the expression of FGF23 and the role it may play locally during the differentiation of these cells. METHODS: ATDC5 cells were differentiated in the presence of insulin, and treated with recombinant FGF23 (rFGF23), inorganic phosphate (Pi) and/or PD173074, an inhibitor of FGF receptors (FGFRs)...

Defibrillation testing is no longer routinely performed after automatic implantable cardioverter-defibrillator (AICD) implantation. However, certain subjects undergoing AICD implantation may be at higher risk of undersensing of ventricular arrhythmias resulting in potentially fatal outcomes. We present the case of a 30-year-old woman with hypertrophic cardiomyopathy (HCM; 'asymmetric septal hypertophy' morphologic variant) and prophylactic AICD who experienced an out of hospital cardiac arrest. AICD interrogation revealed undersensing as a result of intermittent high amplitude electrograms during an episode of ventricular fibrillation (VF)...

In the present study, we aimed to evaluate the co-existence of ophthalmic pterygium with other ocular surface lesions in a cohort of patients from the Cretan population. This is a retrospective evaluation of all pterygia in patients examined and treated at the Department of Ophthalmology of the University Hospital of Heraklion, Greece during an 8-year period (from June 2006 to June 2014). A total of 158 cases was examined. Ocular surface images and medical history were evaluated in order to detect concomitant ocular surface pathological conditions...

A coronary artery fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. However, coronary fistulas to one of the cardiac chambers and coexisting apical myocardial hypertophy are infrequent anomalies, and usually are found unexpectedly. Herein, we report a case in which all three major coronary arteries emptied into the left ventricle with apical hypertrophy, through multiple microfistulas...

INTRODUCTION: Klippel-Trenaunay syndrome (KTS) is a very rare congenital anomaly of blood vessels, characterized by the following clinical triad: varicose superficial veins, port-wine stain and usually bony and soft tissue hypertophy of extremities, most often located in the lower extremities. It is often accompanied by visceral manifestations, and rarely combined with splenomegaly. CASE OUTLINE: A 30-year-old female patient came to the Surgery Clinic because of occasional left hypochondrial pain...

Neuromuscular electrical stimulation (NMES) is a common clinical modality that is widely used to restore (1), maintain (2) or enhance (3-5) muscle functional capacity. Transcutaneous surface stimulation of skeletal muscle involves a current flow between a cathode and an anode, thereby inducing excitement of the motor unit and the surrounding muscle fibers. NMES is an attractive modality to evaluate skeletal muscle adaptive responses for several reasons. First, it provides a reproducible experimental model in which physiological adaptations, such as myofiber hypertophy and muscle strengthening (6), angiogenesis (7-9), growth factor secretion (9-11), and muscle precursor cell activation (12) are well documented...

It has been reported that HMG-CoA reductase inhibitors such as atorvastatin induce vascular smooth muscle cell (SMC) apoptosis in vitro. However, this effect remains to be demonstrated in vivo. The present studies were designed to test the ability of atorvastatin to induce SMC apoptosis in vivo, using the spontaneously hypertensive rat (SHR) as a well-known reference model of SMC apoptosis induction in vivo by cardiovascular drugs including the calcium channel blocker amlodipine. Atorvastatin was administered to SHR for 3 or 6 weeks either alone or together with amlodipine, a drug combination clinically available to patients...

Fabry's disease (FD) is a rare hereditary disorder caused by the loss of alpha galactosidase A activity leading to accumulation of glycosphingolipids in various organs including hypertrophy of the heart. Most reports on cardiac involvement in FD focus on the left ventricular hypertrophy (LVH) and its relation to diastolic function. However, recent studies demonstrated large subset of patients with FD and right ventricle (RV) hypertophy. The accurate depiction of RV volumes, function and mass is possible with cardiovascular magnetic resonance (CMR)...

The purpose of this report was to present an unusual case of an unilateral tonsillar hypertophy caused by actinomycosis. It is an infrequent bacterial infection nowadays. Only five such cases have been reported up to now. Diagnosis is difficult, because there are not specific diagnostic procedures. Medical treatment consists of surgical excision of tonsils and postoperative antibiotic therapy.

BACKGROUND: Reports in adults and children have correlated history of wheezing or asthma with the presence of obstructive sleep-disordered breathing but the mechanism of this epidemiologic association is unknown. The goal of the present study was to examine whether tonsillar hypertophy can explain this association. METHODS: Children were recruited from the Emergency Department and the Pediatric Pulmonology Clinic. History of wheezing requiring treatment (explanatory variable) and snoring > or = 1 night/week (outcome) were recorded and presence of tonsillar hypertrophy (outcome) was assessed...

OBJECTIVE: To describe echographic abnormalities on the proximal (PIP) and distal (DIP) interphalangeal joints of healthy subjects. METHODS: Healthy asymptomatic volunteers under forty were enrolled. Ultrasonography was performed on PIP and DIP 2-5 in the presence of two operators. In B mode, synovial hypertophy and effusion were defined with the OMERACT criteria. In power Doppler mode, the inflammatory activity was evaluated. RESULTS: 46 subjects were enrolled: mean age 25...

Benign Prostatic Hypertrophy (BPH, also known as benign prostatic hyperplasia or benign prostatic enlargement), is one of the most common benign proliferative conditions associated with aging in men and is pathologically characterized by the proliferation of fibroblast/myofibroblast and epithelial cell types in the prostate. Previous studies from our laboratory have shown that the CXC-type chemokines, CXCL5 and CXCL12, are secreted by aging prostate stroma and promote both proliferative and transcriptional responses from prostate epithelial cells...

BACKGROUND: Accelerated atherothrombosis is a common feature in diabetes mellitus patients (DM), which can be related to abnormalities in vascular cell apoptosis and activation leading to the release of procoagulant microparticles (MPs). In DM patients, we hypothesized that circulating levels of biomarkers involved in atherothrombosis processes as well as cardiac and carotid echocardiography variables could be useful in the detection of silent myocardial diagnosed by myocardial perfusion imaging...

OBJECTIVE: Left ventricular (LV) hypertrophy and myocardial fibrosis are considered the main pathological features of acromegalic cardiomyopathy. The aim of the study was to evaluate the proportion of LV hypertrophy and the presence of fibrosis in acromegalic cardiomyopathy in vivo using cardiac magnetic resonance (CMR). DESIGN AND PATIENTS: Fourteen consecutive patients (eight women, mean age 46 +/- 10 years) with untreated active acromegaly were submitted to two-dimensional (2D) colour Doppler and integrated backscatter (IBS) echocardiography and CMR...

This article presents some general principles underlying regenerative phenomena in vertebrates, starting with the epimorphic regeneration of the amphibian limb and continuing with tissue and organ regeneration in mammals. Epimorphic regeneration following limb amputation involves wound healing, followed shortly by a phase of dedifferentiation that leads to the formation of a regeneration blastema. Up to the point of blastema formation, dedifferentiation is guided by unique regenerative pathways, but the overall developmental controls underlying limb formation from the blastema generally recapitulate those of embryonic limb development...
