57% decline in Rhode Island invasive breast cancer mortality between 1987 and 2017: mammography predominates in preventing mortality.

Background: Controversy exists regarding proportional contributions of mammographic screening versus systemic therapy to declining disease-specific mortality of female invasive breast cancer (IBC) in the United States. Understanding relative contributions may help address allocation of medical resources.

Methods: A 31-year (1987-2017) review of Rhode Island (RI) Cancer Registry data of female IBC was carried out in a state with high rates of mammographic screening.

Disseminated cryptococcosis in an immunocompetent patient.

Cryptococcosis is a fungal infection which is commonly associated with immune-compromised state. Disseminated infection in immunocompetent individuals is extremely rare. We present a case of a 56-year-old African American patient who presented with unilateral knee pain and swelling and was subsequently diagnosed with cryptococcal bone mass with dissemination of infection.
