Pseudophilotes fatma (Oberthür, 1890) is a Palearctic butterfly species endemic to the Maghreb region, characterised by a highly restricted distribution and "Endangered" conservation status. Recent field observations in Batna Province, northeastern Algeria, have documented new localities for P. fatma, marking its rediscovery after a 71-year absence.

This « dogma » had been supported by the usual absence of dosimetric advantages with high-energy photons (15 to 18 MV or more), at least for the planning target volume and the dose received by the adjacent organs at risk, and by the neutron component as soon as the photon energy exceeds 10 MV. Recent data could question such a dogma.

For this purpose three different studies were investigated: in vivo, in vitro and Monte Carlo calculations.
Methods: In vivo dosimetry was performed, using OSL NanoDot dosimeters, to determine the dose to the skin of twenty pregnant women.

Introduction: Malignant salivary gland tumor usually involves the parotid gland. Although unusual locations have been reported for such tumors, we here report an extremely rare case of nasal location in a salivary gland adenoma with malignant transformation.
Observation: A 65-year-old man with diabetes and hypertension presented with left nasosinal tumefaction causing nasal obstruction with slow evolution and recent onset of epistaxis and slight telecanthus.
