Background: There is a lack of comprehensive echocardiographic data to allow discrimination of normal versus abnormal mechanical prosthetic tricuspid valve (MPTV) leaflet function. The identification of such parameters is essential to optimize diagnostic and therapeutic measures.

Methods: The authors investigated bileaflet MPTV function by comparing transthoracic echocardiographic data from 21 episodes of leaflet dysfunction due to valve thrombosis in 12 patients with data from 56 individuals with normal MPTV function.

Purpose: The standard of care for treatment of celiac disease (CD) is a stringent lifetime gluten-free diet (GFD). Larazotide acetate (AT-1001) is an anti-zonulin which functions as a gut permeability regulator for treatment of CD. We endeavored to conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) which studied the efficacy and safety of AT-1001 in patients with CD.

Unlabelled: Extraintestinal manifestations of Crohn's disease sometimes occur and can present prior to intestinal symptoms. Ocular manifestations of Crohn's disease are considered rare, with orbital myositis an even rarer manifestation with only a handful of cases reported in the literature. We present the case of a young woman who was diagnosed with orbital myositis, which was initially attributed to pseudotumor cerebri after an extensive negative work-up.

Hematopoietic cell transplantation (HCT) remains until now the only curative modality for hematological manifestations in patients with Fanconi anemia (FA). The doses of alkylating agents used in the conditioning of this patient population before HCT are usually significantly decreased due to the genomic instability of the FA cells. FA patients with renal impairment represent a dilemma because of the need to further modify the conditioning regimen according to the degree of renal impairment to avoid additional toxicity.
