Encephalitis is a hallmark of Nipah virus (NiV) infection in humans. The exact route of entry of NiV into the central nervous system (CNS) is unknown. Here, we performed a spatio-temporal analysis of NiV entry into the CNS of hamsters. NiV initially predominantly targeted the olfactory epithelium in the nasal turbinates. From there, NiV infected neurons were visible extending through the cribri...

Sinonasal schwannomas are rare, benign and slow-growing peripheral nerve sheath tumors without age, race, or gender predilection. We present the unusual case of a 59-year-old female who presented with right-sided retro-orbital pressure and rhinorrhea. Radiographic imaging revealed a mass centered in the right superior nasal cavity with extension through the cribriform plate into the right more ...

A 42-year-old woman presented with symptoms of left-sided nasal obstruction, cerebrospinal fluid (CSF) rhinorrhea, and frequent sinus infections. Radiologic investigation revealed a tumor destructing the left cribriform plate and forming opacifications in the olfactory area. She had left-sided submucosal meningocele, deviating the septum to the right side. Intracranial involvement was not obser...

Iatrogenic injuries of the frontal skull base commonly occur during endoscopic sinus surgery. In this paper, we present a rare case of cranial base injury after transnasal endotracheal intubation for dental surgery. A 61-year-old otherwise healthy man presented at the emergency department with headache, right leg weakness and watery nasal discharge on the left side. He underwent a dental surger...

The skulls of Japanese wolf (Canis hodophilax) were osteometrically examined and compared with those of Akita-Inu. The skull total length was not statistically different between two species. However, significant differences were demonstrated between two species in some ratios concerning the frontal bone. CT examination was carried out in the Japanese wolf skull. The data indicated that the fron...

Four patients undergoing treatment for benign intracranial hypertension presented with spontaneous CSF rhinorrhoea. The four patients, all women, were aged between 33 and 44 years. They had been receiving treatment for benign intracranial hypertension for a period ranging from eight months to 11 years, before developing the CSF leak. There was no history of previous head injury and there were n...

The patient then had a rigid cystoscopy and tri-lobar TURP. The histological examination of the prostate sections showed areas of cribriform growth patterns with cells tending to be columnar in shape. Immmuno histochemical staining showed surrounding basal cells in most of the cribriform structures. This confirmed a diagnosis of focal invasive ductal adenocarcinoma of the prostate (Figure 1 and...

Objective: The objective of this retrospective study was to determine the prevalence data obtained from anatomical structures ethmoid bone evaluated morphometrically on cone beam computed tomography (CBCT) images in a Turkish subpopulation. 
 Methods: CBCT 200 patients which met criteria were selected digital database our university. medial roof height (MERH), cribriform plate (CP), latera...

Introduction: Recurrent bacterial meningitis is a rare clinical phenomenon, but telltale sign of mysterious foe. It an occurrence two or more episodes by different organisms, with the same organism and separated interval at least three weeks. Case Report: We present case 29-year-old gentleman who presented acute pyogenic due to Streptococcus pneumoniae. This second episode confirmed in years an...

BACKGROUND We analyzed the effects of local extension sites on survival in patients with locally advanced maxillary sinus cancer. METHODS The criteria for inclusion in this study were as follows: (1) previously untreated maxillary sinus cancer; (2) squamous cell carcinoma; (3) T4 disease; and (4) curative-intent treatment. The data for 118 patients were obtained from 28 institutions across Ja...
