Sulfa-induced acute eosinophilic pneumonia.

Acute eosinophilic pneumonia (AEP) is an infrequently seen interstitial lung disease secondary to medications. We report a series of 3 case of severe AEP which developed as a result of sulfa medication. 2 patients had received treatment with sulfamethoxazole for acne and 1 was treated with sulfasalazine for colitis.

Helicobacter pylori DNA decreases pro-inflammatory cytokine production by dendritic cells and attenuates dextran sodium sulphate-induced colitis.

Background And Aims: Epidemiological data have recently emerged to suggest Helicobacter pylori may protect against certain chronic inflammatory diseases such as inflammatory bowel disease (IBD). However, the mechanism for the observed inverse association between H pylori and IBD has not been described.

Methods: The frequency of immunoregulatory (IRS) to immunostimulatory (ISS) sequences within the genome of various bacteria was calculated using MacVector software.

A case report of cerebral air embolism after esophagogastroduodenoscopy: diagnosis and management in the emergency department.

Background: Esophagogastroduodenoscopy (EGD) is a rare cause of cerebral air embolism (CAE). To our knowledge, there are only eight previously reported such cases in the history of the procedure.

Objective: To identify clinical causes of CAE that can present to the emergency department (ED) and to understand the appropriate management of CAE.
