Rollet's Mixed Chancre is a clinical presentation of sexually transmitted infections (STI), involving the coexistence of and at the same site of infection. Here, we report a case of Rollet's Mixed Chancre in a 32-year-old Brazilian woman. On physical examination she presented with a unilateral bubo measuring approximately 5 × 3 centimeters in diameter, in association with an ulcerated lesion that evolved for 10 days at the inguinal region. She was successfully treated at a health unit with antibiotics. Rollet's Mixed Chancre, though uncommon, poses diagnostic challenges. This case highlights the importance of considering rare STI manifestations. Moreover, comprehensive STI screening and adherence to treatment guidelines are essential for effective management and prevention of further transmission.

Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum and has shown a significant increase in recent decades. It may be associated with other STIs such as soft chancre or chancroid, which is an uncommon infection in Brazil. The presence of ulcerated genital lesions is associated with a higher risk of HIV transmission.

The response of a tissue equivalent proportional counter (TEPC) in a mixed radiation field with a neutron energy distribution similar to the radiation field at commercial flight altitudes has been studied. The measurements have been done at the CERN-EU High-Energy Reference Field (CERF) facility where a well-characterised radiation field is available for intercomparison. The TEPC instrument used by the ARC Seibersdorf Research is filled with pure propane gas at low pressure and can be used to determine the lineal energy distribution of the energy deposition in a mass of gas equivalent to a 2 microm diameter volume of unit density tissue, of similar size to the nuclei of biological cells.

The aircrew exposure to cosmic radiation can be assessed by calculation with codes validated by measurements. However, the relationship between doses in the free atmosphere, as calculated by the codes and from results of measurements performed within the aircraft, is still unclear. The response of a tissue-equivalent proportional counter (TEPC) has already been simulated successfully by the Monte Carlo transport code FLUKA.
