Radical cystoprostatectomy (RCP) followed by bilateral pelvic lymphadenectomy and urinary diversion remains the gold-standard therapy for men with localized muscle-invasive bladder cancer (MIBC). Prostate cancer might be incidentally detected at the time of RCP with a reported prevalence of 24-51%. Typically, these patients are considered to have clinically insignificant disease, but data from emerging series challenge this assumption and suggest that some of these tumours might be aggressive, or somehow increase the aggressiveness of the associated MIBC, and can negatively influence the patient's overall survival outcomes...

Current methods to quantify RNA dynamics are beset with limitations. Here, we developed a novel stable isotope (D2O)-methodology to quantify RNA synthesis (i.e. ribosomal biogenesis) in cells, animal models, and humans. Firstly, proliferating C2C12 cells were incubated in D2O-enriched media and myotubes (±) 50ng.ml(-1) IGF-1. Secondly, rat quadriceps [untrained n=9; 7-wks interval-"like" training n=13] were collected after ~3-wks D2O (70-Atom%) administration, with body-water enrichment (BWE) monitored via blood sampling...

Dystrophia myotonica (DM) type 1 is an autosomal dominant disorder, caused by a trinucleotide CTG repeat expansion in the 3' untranslated region of the dystrophia myotonica protein kinase (DMPK) gene (chromosome 19q13.3). The disorder affects different organ systems, including the skeletal muscles, ocular lens, lungs, heart and gastrointestinal tract, as well as the endocrine and central nervous systems. The skeletal muscles are most frequently involved, whereby the disorder manifests as myotonia, muscle weakness and amyotrophy...

PURPOSE OF THE STUDY Although total hip arthroplasty (THA) is one of the most successful orthopedic operations, the soft tissue trauma towards the periarticular musculature during surgical approaches remains a critical concern. However, the actual microstructural proof of muscle trauma on the level of the myofiber due to the surgical approach has never been claimed. MATERIAL AND METHODS Patients undergoing THA were prospectively enrolled and either operated by a direct lateral (DL) or a anterolateral minimally invasive approach (ALMI)...

Myositis is characterised by muscle inflammation and weakness. Although generally thought to be driven by a systemic autoimmune response, increasing evidence suggests that intrinsic changes in the muscle might also contribute to the pathogenesis. Long non-coding RNAs (lncRNAs) are a family of novel genes that regulate gene transcription and translation. To determine the potential role of lncRNAs, we employed next generation sequencing to examine the transcriptome in muscle biopsies obtained from two histologically distinct patient populations, inclusion body myositis (IBM) and anti-Jo-1-associated myositis (Jo-1)...

We report the case of a patient treated at the lipid clinic because of high cholesterol levels with consistently elevated creatine kinase concentrations that precluded statin treatment. Electromyography showed a rippling muscle disease pattern. A muscle biopsy confirmed caveolin 3 deficiency, and a missense mutation in the CAV3 gene was identified. The patient could be properly managed with ezetimibe and cholestyramine, which reduced the low-density lipoprotein cholesterol by 30%. He remains asymptomatic after 10 years of follow-up...

Ultrastructural evaluation of skin biopsies has been utilized for diagnosis of mitochondrial disease. This study investigates how frequently skin biopsies reveal mitochondrial abnormalities, correlates skin and muscle biopsy findings, and describes clinical diagnoses rendered following the evaluation. A retrospective review of surgical pathology reports from 1990 to 2015 identified skin biopsies examined by electron microscopy for suspected metabolic disease. A total of 630 biopsies were included from 615 patients...

Nasal augmentation is a popular modern technique requested by many Asian people.There are two kinds of autologous cartilage used to augment the nose at present: carved as a monobloc or diced into pieces. Each approach has its pros and cons.We performed our surgical technique on a group of 28 patients. Twenty of these patients had had several rhinoplasties performed before referral to our hospital; 8 of these patients had undergone a primary rhinoplasty. bilateral conchal, nasal septum, or rib cartilage were harvested, deep temporal fascia or abdominal muscle fascia to be prepared for packing stripped cartilage were also removed at this time...

Background: Muscle wasting is a common complication of Chronic Kidney Disease (CKD) and is clinically important given its strong association with morbidity and mortality in many other chronic conditions. Exercise provides physiological benefits for CKD patients, however the molecular response to exercise remains to be fully determined. We investigated the inflammatory and molecular response to resistance exercise before and after training in these patients. Methods: This is a secondary analysis of a randomized trial that investigated the effect of 8 week progressive resistance training on muscle mass and strength compared to non-exercising controls...

BACKGROUND: Cardiac magnetic resonance (CMR) has demonstrated its utility in the non-invasive diagnosis of cardiac amyloidosis (CA). Our aim was to evaluate the ability of standard Look-Locker sequences to quantify amyloid deposition in CA. METHODS AND RESULTS: Consecutive patients referred for CMR for possible CA were retrospectively evaluated. Positive cardiac biopsy and/or typical pattern of late gadolinium enhancement were required for the diagnosis of CA. Post-contrast T1 values were obtained from Look-Locker sequences, and correlated with markers of severity of disease and major events...

Statin therapy may induce skeletal muscle damage ranging from myalgia to severe rhabdomyolysis. Our previous preclinical studies showed that statin treatment in rats involves the reduction of skeletal muscle ClC-1 chloride channel expression and related chloride conductance (gCl). An increase of the activity of protein kinase C theta (PKC theta) isoform, able to inactivate ClC-1, may contribute to destabilize sarcolemma excitability. These effects can be detrimental for muscle function leading to drug-induced myopathy...

A 41-year-old man presented with gradually progressing proximal-dominant lower limb atrophy and weakness. His brother, mother and maternal aunt had the same symptoms. A physical examination and muscle imaging (CT and ultrasound) showed selective muscle involvement of the bilateral paraspinal, gluteus and posterior groups of lower limb muscles. Based on the characteristic muscle involvement pattern, the clinical findings and the muscle biopsy results, we made a straightforward diagnosis of limb-girdle muscular dystrophy (LGMD) due to a DNAJB6 Phe93Leu mutation based on a targeted gene analysis...
