OBJECTIVE In severely obese individuals and patients with diabetes, accumulation and activation of macrophages in adipose tissue has been implicated in the development of obesity-associated complications, including insulin resistance. We sought to determine whether in a healthy population, adiposity, sex, age, or insulin action is associated with adipose tissue macrophage content (ATMc) and/or ...

The initial suspicion that obesity increases coronary risk has been much sharpened with the demonstration that risk is more tightly linked to abdominal than to peripheral obesity, and tighter yet again when the mass of omental adipose tissue is taken into account. These data suggest that important metabolic differences might exist between adipocytes from different regions, and indeed, it has lo...

Subcutaneous tissue emphysema is observed in a several clinical settings but spontaneous subcutaneous emphysema in the absence of pneumothorax with broncho pleuro subcutaneous fistula is rare. We report a case of spontaneous subcutaneous emphysema secondary to cavitary pulmonary tuberculosis in the absence of pneumothorax.

Subcutaneous emphysema is the presence of gas or air in the subcutaneous tissue plane. The term is generally used to describe any soft tissue emphysema of the body wall or limbs, it can result from benign causes, most commonly secondary to trauma or from a life-threatening infection by gas gangrene or necrotising fasciitis. A case of subcutaneous emphysema involving the upper limb resulting fro...

Rubber band syndrome aka Dhaga is a rare entity mostly seen in young population communities where rubber bands/mauli dhaga are worn over the wrist for decorative or religious purposes. If long duration, then it produces constrictive features burrowing through skin and subcutaneous tissue.

Background: Granular cell tumor (Abrikossoff’s tumor) is a rare and slow-growing tumor of the soft tissue. Originated from the Schwann cells, it is often a benign tumor, but it can be malignant in 1-3% of the cases. Malignant cases can cause significant morbidity and mortality. It may develop in many anatomic locations, especially in the head and neck region, and also in skin and subcutaneous t...

There is growing evidence that the distribution of adipose tissue in the body is of importance in the development of metabolic complications of obesity, such as diabetes, hypertension, and hyperlipidemia. The aim of this study was to identify differentially expressed genes in subcutaneous and omental human adipose tissue in obese men, using a subtractive hybridization strategy. From the obtaine...

INTRODUCTION We recently reported macrophage accumulation in adipose tissue of critically ill patients. Classically activated macrophage accumulation in adipose tissue is a known feature of obesity, where it is linked with increasing insulin resistance. However, the characteristics of adipose tissue macrophage accumulation in critical illness remain unknown. METHODS We studied macrophage mark...

In this study we estimate the subcutaneous tissue counter pressure during drug infusion from a series of injections of insulin in type 2 diabetic patients using a non-invasive method. We construct a model for the pressure evolution in subcutaneous tissue based on mass continuity and the flow laws of a porous medium. For equivalent injection forces we measure the change in the infusion rate betw...
