Evaluating Comorbidities, Natural History, and Predictors of Early Resolution in a Cohort of Children With Chronic Urticaria.

Importance: Chronic urticaria (CU) affects 0.1% to 0.3% of children.

Identification of geographic clustering and regions spared by cutaneous T-cell lymphoma in Texas using 2 distinct cancer registries.

Background: Cutaneous T-cell lymphomas (CTCLs) (mycosis fungoides and its leukemic variant, Sezary syndrome) are rare malignancies. Reports of the occurrence of mycosis fungoides in married couples and families raise the possibility of an environmental trigger for this cancer. Although it has been suggested that CTCL arises from inappropriate T-cell stimulation, to the authors' knowledge no preventable trigger has been identified to date.

Short-term mortality associated with failure to receive home care after hemiarthroplasty.

Background: Hemiarthroplasty is often the treatment of choice after hip fracture, particularly in frail elderly patients. Such patients may benefit from home care after discharge. We assessed factors associated with the receipt of home care and evaluated the risk of death within three months after discharge.

Observational studies of infections in rheumatoid arthritis: a metaanalysis of tumor necrosis factor antagonists.

Objective: Published metaanalyses of tumor necrosis factor (TNF) antagonists and infection have focused on randomized controlled trials, which tend to have short duration, relatively small size, and stringent inclusion/exclusion criteria that may limit enrollment to patients at low risk of infection. We performed a systematic review and synthesis of observational studies of TNF antagonists and infection risk.

Methods: We conducted a systematic literature search of studies estimating overall risk of serious infection after anti-TNF exposure in rheumatoid arthritis (RA).
