Poor adherence to proper Barrett's esophagus screening and surveillance guidelines in patients with newly diagnosed esophageal adenocarcinoma.

Background: Screening for Barrett's esophagus (BE) remains controversial, even for high-risk populations. Our study aimed to evaluate the proportion of patients diagnosed with esophageal adenocarcinoma (EAC) who were not screened for BE or did not receive recommended BE surveillance screening. We then evaluated the relationship between cancer staging and screening/surveillance opportunities.

Leptin Enhances Hepatic Fibrosis and Inflammation in a Mouse Model of Cholestasis.

Leptin is an adipokine with roles in food intake and energy metabolism through its actions on neurons in the hypothalamus. The role of leptin in obesity and cardiovascular disorders is well documented. However, its influence on liver conditions such as cholestasis is poorly understood.

Successful Minimally Invasive Management of a Gastroduodenal Artery Pseudoaneurysm Causing Extrinsic Bile Duct Compression.

Gastroduodenal artery (GDA) pseudoaneurysms are rare clinical entities that typically develop in the setting of chronic inflammation of the pancreas, although idiopathic pseudoaneurysms can occur. Although GDA pseudoaneurysms carry the risk of rupture with resultant hemorrhage, they seldom are reported to cause biliary obstruction. We report a unique case of biliary obstruction secondary to extrinsic compression of the bile duct by a GDA pseudoaneurysm successfully managed by nonoperative means.

Imported fire ant field reaction and immunotherapy safety characteristics: the IFACS study.

Background: Imported fire ants (IFAs) are endemic in the southeastern United States, including Texas; can sting multiple times; and are a well-known cause of anaphylaxis. There are few data available on how many stings typically lead to systemic reactions (SRs). Likewise, there are no reports currently in the literature that characterize the safety of IFA subcutaneous immunotherapy (SCIT).

Antibiotics for the allergist: part 2.

Objective: To review antibiotic use and selection for disorders commonly seen in allergy practice.

Data Sources: MEDLINE searches were performed cross-referencing antibiotic, antimicrobial, management, and treatment with multiple disorders commonly seen in allergy practice. References of the chosen articles were also examined.

Transient dermatographism presenting within the first 18 hours after birth in an otherwise healthy newborn.

We present the first reported instance of transient dermatographism occurring within 18 hours after birth in an otherwise healthy term newborn. The infant's dermatographism resolved without intervention or sequelae, and this report provides guidance for the clinician to follow when presented with similar presentations.

Pruritus, papules, and perspiration.

Background: The development of pruritus and papules with increased body temperature is a common clinical scenario seen in allergy practice, often leading to a diagnosis of cholinergic urticaria.

Objective: To describe an unusual case of miliaria and its significance in the evaluation of patients with pruritic papular eruptions that occur with increased body temperature.

Methods: An 18-year-old woman was referred to a local allergist for the evaluation of cholinergic urticaria.

Severe refractory cholinergic urticaria treated with danazol.

Background: Cholinergic urticaria is a form of physical urticaria triggered by a rise in core body temperature. Antihistamines are the mainstay of treatment; however, adequate symptom control can sometimes be difficult to maintain. Limited data suggest danazol may be an effective alternative in severe, refractory cases.

Cold urticaria: a case report and review of the literature.

Cold urticaria represents a form of physical urticaria. The disorder is uncommon, and patients with the condition are at risk for systemic reactions and thus must be identified, counseled, and treated accordingly. Diagnosis principally is clinical and is confirmed by the results of cold stimulation tests such as placing an ice cube on the patient's forearm.
