Rediscovery of the Endangered Pseudophilotes fatma (Oberthür, 1890) (Lepidoptera: Lycaenidae) in Algeria after 71 years, with an update on its distribution and designation of a lectotype.

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.

[Which photon energy for intensity-modulated radiotherapy and volumetric-modulated arctherapy in 2019?].

For more than a decade, the majority of radiation oncology centres have been delivering intensity-modulated radiotherapy (then volumetric-modulated arctherapy) with 6 MV photons as their standard of care. 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.

Comparative dose levels between CT-scanner and slot-scanning device (EOS system) in pregnant women pelvimetry.

Purpose: To estimate fetal absorbed doses for pregnant women pelvimetry, a comparative study between EOS imaging system and low-dose spiral CT-scanner was carried out. 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.

Degenerative pleomorphic adenoma of the nasal cavity.

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.

[Postvaccination myelitis. Aspect and course followed by MRI].

We report the assessment by MRI of a case of radiculomyelitis after vaccination against tetanus-poliomyelitis. In the acute stage the appearance was an isolated myelitis of the conus medullaris with contrast enhancement. The upper thoracic cord presented central areas of high signal intensity on T2 weighted images.

Role of 3D Display MR Angiography in the Study of Intracranial Aneurysms.

This paper determines the usefulness of threedimensional (3D) phase-contrast (PC) magnetic resonance (MR) angiography with 3D display in characterizing large intracranial saccular aneurysms. Eight patients referred for non invasive confirmation of unruptured aneurysm (n=9) detected by conventional CT and/or MR imaging were studied by 3D PC (VENC of 20 cm/s, 3 axes) in axial acquisition localised on the circle of Willis using a 0.5 T unit (Vectra, GE).

[Value and limits of fine needle aspiration biopsy in Hodgkin disease. Usefulness in developing countries].

The efficiency of a diagnostic procedure is evaluated by the percentage of subjects accurately identified, as either suffering from the disease looked for (true positive, TP) or not (true negative, TN). Sensitivity and specificity are the percentage of TP or TN, respectively, accurately identified. Cytological diagnosis of Hodgkin's disease (HD) was evaluated; smears were made from fine-needle aspiration.
