Asymptomatic Gangrenous Acute Cholecystitis: A Life-Threatening Condition.

Gangrenous gallbladder (GGB) is a life-threatening complication of acute cholecystitis, which happens due to gallbladder (GB) wall ischemia and necrosis. Delaying the diagnosis of GGB is life-threatening and may happen in asymptomatic patients. We present a case of an elderly male patient with a history of gastric carcinoid tumor, with partial gastric resection, who presented with generalized weakness and jaundice.

Right Upper Extremity Idiopathic Primary Lymphedema in a 2-Year-Old Child.

Lymphedema of an extremity at birth can be an alarming finding. Our patient presented with difficulty breathing and productive cough and was found to have primary lymphedema of the right upper extremity since birth. Further testing was mostly unremarkable except for imaging that revealed many splenic lesions.

Spectral Image Processing for Museum Lighting Using CIE LED Illuminants.

This work presents a spectral color-imaging procedure for the detailed colorimetric study of real artworks under arbitrary illuminants. The results demonstrate this approach to be a powerful tool for art and heritage professionals when deciding which illumination to use in museums, or which conservation or restoration techniques best maintain the color appearance of the original piece under any illuminant. Spectral imaging technology overcomes the limitations of common area-based point-measurement devices such as spectrophotometers, allowing a local study either pixelwise or by selected areas.
