Pathological Fracture on a Cyst-Like Mandibular Lesion Revealing a Primary Intraosseous Squamous Cell Carcinoma: A Rare Clinical Case and Review of the Literature.

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant tumor originating from remnants of odontogenic epithelium within the central jaw bone. The majority of the PIOSCC cases are diagnosed incidentally on histological findings while a potential malignancy wasn't necessarily determined at first on initial investigations. The diagnosis of PIOSCC is challenging and relies on ruling out other types of carcinomas, including metastatic tumors from other primary sites.

Facial dog bites in children: A public health problem highlighted by COVID-19 lockdown.

Background: Stay-at-home injunction during COVID-19 pandemic led to new dynamics in households and increased the risk of domestic accidents involving pets. The aim of the study was to demonstrate an increase of facial dog bites in children during first lockdown period in France, compared to the same period in 2018 and 2019. Secondary objective was to investigate the demographics and circumstances in which dog bites occurred.

Changes in arbuscular mycorrhizal fungal communities, mycorrhizal soil infectivity, and phosphorus availability under Chromolaena odorata (Asteraceae) invasions in a West-African forest-savanna ecotone.

Substantial areas of agricultural lands in Sub-Saharan Africa have been invaded by Chromolaena odorata (Asteraceae), but the consequences for arbuscular mycorrhiza fungi (AMF) remains poorly understood. This study explores changes in diverse AMF community attributes and soil available phosphorus following C. odorata invasion in forest and savanna fragments in Côte d'Ivoire (West Africa).

Mental Nerves in the Lower Lip: Anatomical Basis for the Recovery of Sensation following Inferior Alveolar Nerve Damage.

Background: Inferior alveolar nerve damage is one of the most common complications of surgery on the lower third of the face. It can have a significant psychological and social impact, and its evolution varies in terms of the duration and degree of recovery. In the literature, few studies adequately explain this phenomenon.

Duplication of the internal carotid artery and segmental aplasia of the vertebral arteries.

The internal carotid artery mainly supplies the brain. As the internal carotid artery contributes to the formation of the cerebral arterial circle, its variations are relevant in imaging, interventional radiology, and surgery. Knowledge of these variations is important for vascular anastomosis in free flap reconstruction and in arterial ligatures for haemostasis.
