Usability and acceptability of self-testing for hepatitis C virus infection among the general population in the Nile Delta region of Egypt.

Background: Self-testing for hepatitis C virus antibodies (HCVST) may be an additional strategy to expand access to hepatitis C virus (HCV) testing and support elimination efforts. We conducted a study to assess the usability and acceptability of HCVST among the general population in a semi-rural, high-HCV prevalence region in Egypt.

Methods: An observational study was conducted in two hospitals in the Nile Delta region.

SECONDARY NEUTRON DOSES IN A PROTON THERAPY CENTRE.

The formation of secondary high-energy neutrons in proton therapy can be a concern for radiation protection of staff. In this joint intercomparative study (CERN, SCK•CEN and IBA/IRISIB/ULB), secondary neutron doses were assessed with different detectors in several positions in the Proton Therapy Centre, Essen (Germany). The ambient dose equivalent H(*)(10) was assessed with Berthold LB 6411, WENDI-2, tissue-equivalent proportional counter (TEPC) and Bonner spheres (BS).

A Bonner Sphere Spectrometer for pulsed fields.

The use of conventional Bonner Sphere Spectrometers (BSS) in pulsed neutron fields (PNF) is limited by the fact that proportional counters, usually employed as the thermal neutron detectors, suffer from dead time losses and show severe underestimation of the neutron interaction rate, which leads to strong distortion of the calculated spectrum. In order to avoid these limitations, an innovative BSS, called BSS-LUPIN, has been developed for measuring in PNF. This paper describes the physical characteristics of the device and its working principle, together with the results of Monte Carlo simulations of its response matrix.

Cavitating lung lesion as a manifestation of inflammatory tumor (pseudotumor) of the lung: A case report and literature review.

Patient: Female, 60 FINAL DIAGNOSIS: Inflammatory pseudotumor of the lung Symptoms: Cough dry • fever

Medication: - Clinical Procedure: - Specialty: -

Objective: Rare disease.

Background: Inflammatory pseudotumor of the lung involves a benign, non-neoplastic lung lesion of unknown etiology.

Case Report: We present a case of a 60-year-old female smoker who had been under intermittent immunosuppressive medication for discoid lupus, who was admitted to hospital with fever of 39.

Comparison of the performance of different instruments in the stray neutron field around the CERN Proton Synchrotron.

This paper discusses an intercomparison campaign carried out in several locations around the CERN Proton Synchrotron. The locations were selected in order to perform the measurements in different stray field conditions. Various neutron detectors were employed: ionisation chambers, conventional and extended range rem counters, both commercial and prototype ones, including a novel instrument called LUPIN, specifically conceived to work in pulsed fields.
