Viral infection as an inciting event for development of chronic rhinosinusitis: A population-based study.

Viral infections lead to a greater than twofold increased risk of developing chronic rhinosinusitis within 1 year. Viral infections lead to a greater than twofold increased risk of developing chronic rhinosinusitis within 1 year. Recurrent viral infections pose a greater risk of chronic rhinosinusitis than single episodes.

Fundamental Limits of Feedback Cooling Ultracold Atomic Gases.

We investigate the fundamental viability of cooling ultracold atomic gases with quantum feedback control. Our Letter shows that the trade-off between the resolution and destructiveness of optical imaging techniques imposes constraints on the efficacy of feedback cooling, and that rapid rethermalization is necessary for cooling thermal gases. We construct a simple model to determine the limits to feedback cooling set by the visibility of density fluctuations, measurement-induced heating, and three-body atomic recombination.

Colonic non-hodgkin lymphoma presenting as splenomegaly splenocolic fistula in person living with HIV: A case report.

Primary colonic lymphoma is an infrequent malignancy among other large bowel malignancies, and the risk of the spread of tumor cells through a spleno-colic fistula is a unique finding and hence noteworthy. We report a case of a 55-year-old man living with HIV on anti-retroviral treatment for 12 years, who presented to the emergency room with complaints of generalized weakness and left-sided abdominal discomfort. Further examination and evaluation revealed massive splenomegaly with a thickened splenic flexure of the colon and spleno-colic fistula.

Severe Hemolytic Anemia After Mothball Ingestion Complicated by an Undiagnosed Enzyme Deficiency: A Case Report.

Ingestion of mothballs containing naphthalene or paradichlorobenzene is known to cause hemolysis and methemoglobinemia secondary to severe oxidative stress, affecting the oxygen delivery system of the body. The gradual accumulation of oxidizing radicals in the setting of restricted glutathione availability leads to the oxidization of hemoglobin and other body proteins, ultimately causing cell destruction. In the setting of glucose-6-phosphate dehydrogenase deficiency (G6PDD), more pronounced symptoms and poor prognosis are anticipated as adequate nicotinamide adenine dinucleotide phosphate is not generated to protect red blood cells from oxidative injury, potentiating the hemolytic process further.
