Myxoinflammatory Fibroblastic Sarcoma of the Hand.

Myxoinflammatory fibroblastic sarcoma is an ultra-rare tumor type with a prevalence of fewer than two per 100,000 people. The tumor poses a challenge because it can be misdiagnosed as a benign lesion in clinical and radiological investigations, causing serious morbidity in patients. We present the case of a 33-year-old patient who presented with painless hand swelling that was misdiagnosed as lymphaticovenous malformation based on magnetic resonance imaging.

A Systematic Review and Meta-analysis of Randomized Controlled Trials Comparing Surgical versus Conservative Treatments for Acute Undisplaced or Minimally-Displaced Scaphoid Fractures.

Background: Surgical and conservative methods have been reported by various studies for high rates of fracture union and subsequent regain of function among patients with undisplaced or minimally-displaced scaphoid fractures. Hence, this study aims to analyze the best available evidence to comprehend the relative benefits and risks of these therapeutic options.

Methods: A systematic search of the literature from different databases and search engines was performed with strict eligibility criteria to obtain the highest quality of evidence.

Obesity-induced DNA hypermethylation of the adiponectin gene mediates insulin resistance.

Adiponectin plays a key role in the regulation of the whole-body energy homeostasis by modulating glucose and lipid metabolism. Although obesity-induced reduction of adiponectin expression is primarily ascribed to a transcriptional regulation failure, the underlying mechanisms are largely undefined. Here we show that DNA hypermethylation of a particular region of the adiponectin promoter suppresses adiponectin expression through epigenetic control and, in turn, exacerbates metabolic diseases in obesity.

Mature adipocyte proteome reveals differentially altered protein abundances between lean, overweight and morbidly obese human subjects.

Overweight (OW) and obese individuals are considered to be graded parts of the scale having increasing weight as a common feature. They may not, however, be part of the same continuum and may differ metabolically. In this study we applied an untargeted proteomic approach to compare protein abundances in mature adipocytes derived from the subcutaneous adipose tissue of overweight and morbidly obese female subjects to those of lean age matched controls.
