Background: At least 5-10% of malignancies occur secondary to an underlying cancer predisposition syndrome (CPS). For patients with a CPS, cancer surveillance is recommended with the goal of identifying malignancy earlier, in a presumably more curable form. Surveillance protocols, including imaging studies, lab work, and procedures, can be complex, differing based on age, gender, and syndrome, which may adversely affect adherence. Mobile health (mHealth) applications have been utilized in the oncology field and could help to facilitate adherence to cancer surveillance protocols. Methods: Applying a user-centered mobile app design approach, patients with a CPS and/or primary caregivers were interviewed to identify current methods for care management and barriers to compliance with recommended surveillance protocols. Broad themes from these interviews informed the design of the mobile app, HomeTown, subsequently evaluated by usability experts. The design was then converted into software code in phases, evaluated by patients and caregivers in an iterative fashion. User population growth and app usage data were assessed. Results: Common themes identified include general distress surrounding surveillance protocol scheduling and results, difficulty remembering medical history, assembling a care team, and seeking resources for self-education. These themes were translated into specific functional app features including push reminders, syndrome-specific surveillance recommendations, ability to annotate visits and results, storage of medical histories, and links to reliable educational resources. Conclusions: Families with CPS demonstrate a desire for mHealth tools to facilitate adherence to cancer surveillance protocols, reduce related distress, relay medical information, and provide educational resources. HomeTown may be a useful tool for engaging this patient population.

Patients with DNA double-strand breakage repair disorders are at increased risk of malignancy which is often difficult to treat given underlying sensitivity to chemotherapy and radiotherapy, lending an important role to hematopoietic stem cell transplantation. The choice of conditioning regimen used must balance reducing risk of rejection with minimizing excessive toxicity from myeloablative chemotherapy or ionizing radiation. We describe successful engraftment following a nonmyeloablative hematopoietic stem cell transplantation in a patient with Ligase IV syndrome and numerous pretransplant complications including malignancy, cardiac failure, and secondary hemophagocytic lymphohistiocytosis. Congruent with prior reports, a reduced intensity regimen appears efficacious in Ligase IV syndrome patients.

New therapies for retinitis pigmentosa (RP) have led to patients desiring more information about their disease. We assessed the readability, content, and accountability of online health information for RP and its treatments.Two internet queries were performed: one pertaining to the condition RP, and another pertaining to treatments of RP. Three analyses were performed on the top search results that met eligibility criteria: (1) A readability analysis produced an average reading level; (2) A content analysis was conducted to score each source on the accuracy, completeness, clarity, and organization of the content; and (3) An accountability analysis was performed to evaluate adherence to accountability benchmarks, including authorship, attribution, disclosure, and currency.The mean reading level was 12.0 (SD = 3.2, 95% CI = 11.0-13.0) for the 8 RP webpages and 12.5 (SD = 3.1, 95% CI = 11.7-13.4) for the 10 RP treatment webpages. The mean content score for RP sites was 21.3 of 32 points (SD = 4.1, 95% CI = 19.5-23.0). The mean content score for RP treatment sites was 5.5 out of 16 points (SD = 3.7, 95% CI = 4.1-6.9). The inter-rater reliability was 0.973 (Cronbach's alpha). For RP sites, the mean accountability score was 2.6 out of 4 points (SD = 0.9, 95% CI = 1.9-3.4). For RP treatment sites, the mean accountability score was 2 out of 4 points (SD = 0.9, 95% CI = 1.4-2.6).Our data suggest that the online information available to patients regarding RP and RP treatment options exceeds the AMA-recommended sixth-grade reading level and contains gaps in content relevant to patients.
