Associations of self-reported allergic diseases and musculoskeletal problems in children: A US population-based study.

Background: Previous studies have found increased rates of musculoskeletal problems in adults with allergic disease, but whether this association holds true for children is unknown.

Objective: To investigate the association of bone, joint, and muscle problems in children with a history of allergic disease.

Methods: Data were obtained from the 2007 Child and Adolescent Health Measurement Initiative.

Penile and Scrotal Swelling: An Underrecognized Presentation of Crohn's Disease.

Background: Penile and scrotal swelling can occur as an extraintestinal manifestation of Crohn's disease (CD) and is thought to be an uncommon form of metastatic CD (MCD). Because of the rarity of this manifestation, much is unknown concerning the presentation, treatment, and response to therapy in children with genital MCD.

Methods: Boys ages 1 to 17 years presenting with genital edema and a confirmed diagnosis or strong suspicion of CD who were evaluated at the Mayo Clinic between 1996 and 2014 were included for review.

Diagnostic imaging in paraneoplastic autoimmune multiorgan syndrome: retrospective single site study and literature review of 225 patients.

Background: The utility of diagnostic imaging in paraneoplastic autoimmune multiorgan syndrome (PAMS) is unknown.

Methods: We examined the role of diagnostic imaging in patients with PAMS evaluated at our tertiary referral center (at Mayo Clinic, Rochester, MN, USA) and in the English literature between January 1, 1996, and August 31, 2012.

Results: We included 17 patients from our institution and 208 patients from the literature review.

Specific causes of death in patients with bullous pemphigoid as measured by death certificate data: a retrospective cohort study.

Background: Mortality rates in patients with bullous pemphigoid (BP) are higher than those in age-matched counterparts. However, the specific causes of death in BP subjects have not been evaluated systematically.

Objectives: We sought to characterize the causes of death in patients with BP as recorded by death certificate and to compare these with death data for age- and location-matched control subjects.

Ulcerated plaques in the pelvic region of an adult female.

Cutaneous metastatic mammary carcinoma may occur in patients with a history of breast carcinoma. Cutaneous metastases typically present as firm papulonodules on the chest. We describe a rare case of cutaneous metastatic mammary carcinoma arising in a 45-year-old woman presenting as painful, indurated plaques with ulceration in the pelvic region.
