Bilateral inverted papilloma: Case report and literature review.

Inverted papilloma is a rare, benign epithelial tumor of the nasal and sinus cavities with an unclear etiology. It usually presents as unilateral nasal obstruction. Diagnosis is histological, and treatment is primarily surgical.

Primary nasosinus meningioma, an etiology masks another: Case report.

Introduction And Importance: Extracranial meningiomas of the sinonasal tract are rare tumors. The diagnosis is not generally evident. We report, through an observation, the clinical particularities, the diagnostic difficulties and the therapeutic approach of primary sinonasal meningiomas.

Sphenoethmoidal Meningocele: Endoscopic Approach.

The sphenoethmoidal meningocele is a herniation of the meninges through a communication of the skull base with an aeric cavity. It means the presence of an osteomeningeal breach, which is manifested by cerebrospinal rhinorrhea and nasal obstruction. iIs diagnosis is based on a very specific radiological assessment and biology allows the dosage of certain substances to confirm the nature of the cerebrospinal fluid, such as beta-2-transferrin, Once the breach has been found, the endoscopic route exclusively allows the pathology to be treated and the defect to be reconstructed using different materials before the occurrence of serious complications such as meningitis.

Diagnostic and therapeutic determinants in parathyroid surgery: A retrospective cohort study.

Introduction: The systematic realization of biochemical and radiological examinations of the parathyroid has increased the incidence of primary hyperparathyroidism; which explains the increasing incidence of parathyroid surgery. Our study aims to predict the factors determining the diagnosis and management of parathyroid adenomas.

Methods: We included 87 patients who presented with hyperparathyroidism and underwent parathyroid surgery.

Hypothyroidism and multinodular goiter due to tubercular thyroiditis: A rare coexistence.

Introduction And Importance: the diagnosis of thyroid tuberculosis is often difficult, on account of its rarity even in countries with endemic tuberculosis, and on account of its non-specific clinical, biological and radiological presentation.

Case Presentation: A 38-year-old woman presented with swelling in the anterior part of the neck for 7 years. Clinical and radiological examination found multinodular goiter and fine needle aspiration cytology showed colloidal cells with follicular cells.

Concomitant abducens and facial nerve palsies following bone temporal fracture: Case report.

Introduction: Lesions of the nervus abducens, the 6th cranial nerve tend to be rare, usually occur suddenly following head injuries. The existence of the association of several lesions of the cranial pairs in spite of their rarity must lead the clinician to establish a complete lesion assessment before any cranial trauma.

Case Report: We describe an illustrative case of sixth nerve palsy associated to facial nerve palsy following a motor vehicle accident.

Middle ear neuroendocrine tumor: a case report.

Neuroendocrine tumors are extremely rare in the middle ear. These tumors represent a spectrum of tumors with a diverse range of molecular abnormalities, functionality and anatomical locations. We present a rare case of middle ear neuroendocrine tumor, review the pathology and differential diagnosis of the tumors, and discuss the management and follow-up of patients with these tumors.

Cervical sympathetic chain schwannoma masquerading as a vagus nerve: a case report.

Schwannoma arising from the cervical sympathetic chain are rare slow-growing tumors which represent a diagnostic challenge. We report a 80-year-old female patient presented with anterior neck triangle swelling. The radiological assessment was based on computed tomography and magnetic resonance imaging, which led to a preoperative diagnosis of vagus nerve schwannoma.

Bilateral blindness following a stabbing assault: A case report.

Introduction: Stabbing is relatively frequent in Morocco and constitutes a major public health concern. Our observation is interesting by the particularity and the aggressiveness of the trauma leading to an irreversible bilateral blindness.

Case Presentation: The present observation relates to a patient who was victim of a stabbing assault.

Chondromyxoid fibroma of zygomatic bone: A case report.

Introduction: Chondromyxoid fibroma (CMF) is a rare benign bone tumor that typically affects long bones, only 2% of CMFs involved facial bones or skull, zygomatic localization is extremely rare with only 8 cases reported in literature so far.

Presentation Of Case: We report a case of 88 old years patient with painful swelling in the right zygomatic around 1 year, progressively increasing in volume, Computed tomography (CT) scan showed an osteolytic lesion in the right zygomatic bone with cortical destruction. Surgical management consisted of bone curettage using intra oral approach, the histopahological findings were in favor of the diagnosis of CMF.

Mandibular tuberculosis fortuitously discovered after surgical resection of an ameloblastoma: A case report.

Introduction: Mandibular localization of tuberculosis is rare and represents less than 2% of skeletal locations. Its clinical and radiological features are not specific. In this paper, we report a case of fortuitous discovery of mandibular tuberculosis after a histopathological analysis of the surgical resected specimen during surgical management of an ameloblastoma.

Adult-onset woakes' syndrome: Report of two cases.

Introduction: Woakes' syndrome is a rare condition commonly defined as recurrent sinonasal polyposis with consecutive destruction of the nasal pyramid. Till now, only a few cases have been reported in the literature. The purpose of this paper is to present the features of woakes' syndrome through two new clinical cases, adding some valuable insight to the recently reported cases.

Internal jugular vein thrombosis by sewing needle ingestion.

Introduction: The internal jugular vein thrombosis is usually due to intravenous drug abuse, prolonged central venous catheterization or deep head-neck infections or trauma. Related malignancies, or inflammatory etiologies are described. Our case is interesting by the ingestion of a sewing needle that passes from the pharynx to the internal jugular vein via migration, leading to life-threatening complications: deep neck space infection and internal jugular vein thrombosis.

Schwannoma of the external auditory canal: An exceptional site.

Introduction: Schwannomas are benign solitary neural tumours that are only exceptional located in the external auditory canal, as only a few cases have been reported in the literature.

Case Report: We report a case of schwannoma of the external auditory canal in an 18-year-old man admitted for an isolated mass of the initial segment of the right external auditory canal visible to the naked eye, obstructing all of the external auditory meatus. Computed tomography of the temporal bone showed an isolated mass of the external auditory canal.

[Malignant otitis externa caused by Candida albicans].

Malignant otitis externa is also referred to as skull base osteomyelitis. Pseudomonas aeruginosa is the most common offending pathogen. However, fungal origin is not uncommon.

[Frontal sinus barotrauma: about a case and review of the literature].

Sinus barotrauma is the second most frequently reported injury after middle ear barotrauma. The front sinus is the most common site affected. This is a rare and specific pathology.

[External auditory canal cholesteatoma].

A fibrin antibody binding to fibronectin induces potent inhibition of angiogenesis.

Antiserum from rabbits immunised with pure human fibrinogen was affinity purified on immobilised fibrin fragment E (FFE). This FFE antibody (Ab) induced significant growth inhibition of a human cancer xenograft in mice and suppression of tumour angiogenesis, leaving no formed vessels and only CD31-staining endothelial fragments in place. Tubule formation of HUVEC on MatrigelTM was also significantly inhibited by FFE Ab.

Instruction of circulating endothelial progenitors in vitro towards specialized blood-brain barrier and arterial phenotypes.

Objective: The vascular system is adapted to specific functions in different tissues and organs. Vascular endothelial cells are important elements of this adaptation, leading to the concept of 'specialized endothelial cells'. The phenotype of these cells is highly dependent on their specific microenvironment and when isolated and cultured, they lose their specific features after few passages, making models using such cells poorly predictive and irreproducible.

In vitro and in vivo analysis of endothelial progenitor cells from cryopreserved umbilical cord blood: are we ready for clinical application?

Umbilical cord blood (CB) represents a main source of circulating endothelial progenitor cells (cEPCs). In view of their clinical use, in either the autologous or allogeneic setting, cEPCs should likely be expanded from CB kept frozen in CB banks. In this study, we compared the expansion, functional features, senescence pattern over culture, and in vivo angiogenic potential of cEPCs isolated from fresh or cryopreserved CB (cryoCB).
