Ultrasonography is an effective tool for breast cancer screening in individuals with severe motor and intellectual disabilities.

BACKGROUND: Individuals with severe motor and intellectual disabilities have become an aging population, and high cancer morbidity and mortality are critical issues affecting their survival. Cancer screening is a crucial method of resolving this issue; however, a suitable screening method for them has not been established. METHODS: We used ultrasonography alone and performed breast cancer screening for women over 30 years old in our facility from 2016 to 2023. We observed the outcomes and calculated the recall/detection rate in this screening. RESULTS: Three cases among 379 tested positive in this screening, all of which underwent radical surgery. They are alive and well without relapse present. We detected these breast cancer cases with a low recall rate. CONCLUSION: We were able to successfully detect breast cancer cases using ultrasonography alone. Ultrasonography is an effective and feasible tool for breast cancer screening in individuals with severe motor and intellectual disabilities.

Early intervention for late-onset ornithine transcarbamylase deficiency.

We report the case of a family with late-onset ornithine transcarbamylase deficiency (OTCD). Several family members had died from OTCD, and the c.221G>A, p.Lys221Lys mutation was detected at the 3' end of exon 6 of OTC in the X-chromosome of some members. We provided genetic counseling on pregnancy, delivery, and neonate management to a 4th-generation female carrier and decided on metabolic management of her child from birth. Two male patients were diagnosed with late-onset OTCD on the basis of blood amino acid and genetic analysis, and they received arginine supplementation from the asymptomatic, early neonatal period. These children grew and developed normally, without decompensation. Patients with late-onset OTCD can and should be diagnosed and treated in the early neonatal period, especially those from families already diagnosed with late-onset OTCD, and family members must be provided with genetic counseling.
