Complete response of skull base inverted papilloma to chemotherapy: Case report. [PDF]

open access: yes, 2017
BackgroundInverted papilloma (IP) is the most common benign sinonasal neoplasm. Endoscopic techniques, improved understanding of pathophysiology, and novel surgical approaches have allowed rhinologists to treat IPs more effectively, with surgery being ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

[Third cranial nerve palsy in sphenoid sinusitis].

open access: yesActa medica portuguesa, 2016
Sphenoid sinus disease is particular not only for its clinical presentation, as well as their complications. Although rare, these may present as cranial nerve deficits, so it is important to have a high index of suspicion and be familiar with its diagnosis and management.

Ossifying fibromas of the paranasal sinuses: diagnosis and management

open access: yesActa otorhinolaryngologica italica, 2015
SUMMARY Fibro-osseous benign lesions rarely affect the sinonasal tract and are divided into 3 different entities, namely osteoma, fibrous dysplasia and ossifying fibroma.

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

Extranodal Rosai-Dorfman disease involving paranasal sinuses, orbits and anterior cranial fossa

open access: yesIndian Journal of Neurosurgery, 2014
Rosai-Dorfman disease (RDD) is a rare, benign pseudolymphatous condition, predominantly involving lymph nodes. Although several cases of extra-nodal involvement have been reported previously, central nervous system involvement, particularly in the ...

The Development of the Human Female Reproductive Tract. Part 1: Uterine Tube and Uterus

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The uterine tubes and uterus develop from the paramesonephric (Müllerian) ducts. Most experimental data are obtained in rodents. Since the (micro‐)anatomy of the murine urogenital tract differs from that in humans, evaluation of the translatability of mouse data to human development is relevant.

The Development of the Human Female Reproductive Tract: Part 2—Vagina

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Urogenital epithelium replaces the original paramesonephric (Müllerian) epithelium in the human fetal vagina. We re‐investigated this cell replacement histologically and with three‐dimensional reconstructions. In the lesser pelvis, both Müllerian ducts fuse to form the uterovaginal canal.
