Introduction: Extra-pulmonary tuberculosis (EPTB) arising in extra-oral region in head and neck are rare, and when swellings arise from other sites such as infraorbital region, cheek, etc, tuberculosis is not usually considered for the differential diagnosis (DD) and often the diagnosis is missed and appropriate treatment is delayed. Case Report: We report a rare entity of pri...

BACKGROUND Colorectal cancer is the third commonest cause of cancer death in UK. It commonly metastasises to the liver but rarely to small bones. CASE PRESENTATION We describe a case of a patient with adenocarcinoma of the descending colon who presented preoperatively with a right supraclavicular swelling. Subsequent imaging and cytology of the lesion revealed this to be a metastasis to the r...

The most common benign salivary gland tumor is pleomorphic adenoma. They can attain giant proportions and weigh several kilograms. They can cause facial disfigurement and, if untreated, could lead malignant transformation. This image depicts a 7.5 kg pleomorphic adenoma of right submandibular gland with malignant change in a 55-year-old male.

DOI: 10.1590/S1679-45082014AI2606 A 22-day-old male infant, the first child of nonconsanguineous parents, who was delivered from a followed-up and normal pregnancy, and without alterations in analytical and echographic evaluation. He was born by cesarean section at 39 weeks, because the labor failed to progress, with Apgar score of 9 at 1 minute and of 10 at 5 minute, weighting 3,240g at birth ...

Abstract. We develop a general theory of the swelling kinetics of polymer gels, with the view that a polymer gel is a two-phase fluid. The model we propose is a free boundary problem and can be used to understand both contraction and swelling, including complete dissolving or dehydration of polymeric gels. We show that the equations of motion satisfy a minimum energy dissipation rate principle ...

excessive production and stockpile of scrap tires cause some environmental and sanitary risks throughout the world. to manage these materials, possible use of soil-tire mixtures has been recently propounded in civil engineering projects. a few studies previously have been conducted to evaluate behavior of clay-tire mixtures, while swelling properties, consolidation and settlement characteristic...

this experiment was conducted with broiler chickens to evaluate the effects of high and low swelling bentonite (natural and processed by cuso4) supplementation in diets on performance and carcass traits. a total of 300 day-old aryan broiler’s chicks were used in a completely randomized design with 5 dietary treatments. six pen replicates of 10 chicks were assigned to each of five dietary treatm...

The physical properties of fish liver and rat liver mitochondria were compared as a function of temperature and osmotic pressure. The data indicate that fish mitochondria are more flexible and swell at a more rapid rate over a 0 to 30 degrees C temperature range, whereas the rates of swelling at 30 to 40 degrees C are comparable. The swelling rates of both fish and rat mitochondria vary with te...

By means of computerized tomography (CT) diffuse cerebral swelling has been shown to exist in the early stages of severe acute head injury. But, to our knowledge, it has not been intensively studied in blunt head trauma. The purpose of this study is to elucidate the clinical features, pathogenesis and outcome of the patients with diffuse cerebral swelling occurring in the case of blunt head tra...
