A 3D Finite Element evaluation of the exophthalmia reduction [PDF]

Acta of Bioengineering and Biomechanics 4(1) (2003) 166-167, 2006
This paper presents a first evaluation of the feasibility of Finite Element modelling of the orbital decompression, in the context of exophthalmia. First simulations are carried out with data extracted from a patient TDM exam. Results seem to qualitatively validate the feasibility of the simulations, with a Finite Element analysis that converges and ...

Self-supervised learning for classifying paranasal anomalies in the maxillary sinus [PDF]

arXiv
Purpose: Paranasal anomalies, frequently identified in routine radiological screenings, exhibit diverse morphological characteristics. Due to the diversity of anomalies, supervised learning methods require large labelled dataset exhibiting diverse anomaly morphology.

Impact of MYD88 and/or CD79B mutations on central nervous system relapse in patients with diffuse large B‐cell lymphoma

British Journal of Haematology, EarlyView.
This study examined the effect of MYD88L265P (myeloid differentiation primary response gene 88 mutation L265P) and/or CD79BY196 (cluster of differentiation 79B gene mutation Y196) on central nervous system (CNS) relapse in 270 patients with newly diagnosed diffuse large B‐cell lymphoma.

Atypical presentation of cystic schwannoma of the sphenoid sinus: a nonsolitary mass with osseous, intracranial and cavernous sinus invasion

The Pan African Medical Journal, 2018
Although nearly half of all schwannomas involve the head and neck region, nasal and paranasal sinus presentations are quite rarely seen. Cystic schwannoma, characterized by cyst formation lined by S-100 protein positive membrane-like structures is very ...
