The human body dimensions are affected by ecological, biological, geographical, racial, sex, and age factors. Craniofacial measurements can be considered to be one of the important tools for determination of the morphological characteristics of the head and face. In this study, which was conducted on Persian adolescents living in Kerman/Iran, different forms of head and face were determined for using in various aspects of medicine. The study was conducted on 732 participants including 366 males and 366 females in the age of 18-20-year-old...

BACKGROUND: Various complications after C1 lateral mass and C2 pedicle screw fusion surgery (C1LM-C2PSFS) have been reported. However, to our knowledge, this is the first report of contusional cerebellar hemorrhage caused by placement in the protrusion (chin-out) position after C1LM-2PSFS. CASE DESCRIPTION: An 81-year-old woman complaining of gait disturbance and clumsiness of both hands was diagnosed with cervical myelopathy with atlantoaxial subluxation. After we performed C1LM-C2PSFS, her neurologic deficits gradually improved, and there was no radiologic evidence of construct failure...

James Brady, the White House press secretary during President Ronald Reagan's first term in office, was 1 of 4 people (including the President) wounded during an attempted assassination attempt on President Reagan's life on March 30, 1981. John Hinckley, Jr. was found not guilty of this attempt by reason of insanity. The assassination attempt was a ploy by Hinckley, Jr. to impress the actress Jodie Foster. Brady was the most seriously injured of the 4 who were wounded. He suffered a gunshot wound to the left forehead that traveled through the left frontal lobe, corpus callosum, and then into the right frontal and temporal lobes...

BACKGROUND: Although the term paraclival carotid pervades recent skull base literature, no clear consensus exists regarding boundaries or anatomical segments. OBJECTIVE: To reconcile various internal carotid artery (ICA) nomenclatures for transcranial and endoscopic-endonasal perspectives, we reexamined the transition between lacerum (C3) and cavernous (C4) segments using a C1-C7 segments schema. In this cadaveric study, we obtained a 360°-circumferential view integrating histological, microsurgical, endoscopic, and neuroradiological analyses of this C3-C4 region and identified a distinct transitional segment...

Or Cohen-Inbar
Pituitary adenomas represent one of the most common types of intracranial tumors, accounting for 10-20% of intracranial tumors. While their macroscopic appearance and anatomical location are relatively homogeneous, pituitary tumors differ widely, generating a variety of neurological and endocrine clinical sequelae. Treatment options include hormone suppressive medical therapy, microscopic or endoscopic neurosurgical resection, radiosurgery, radiation therapy, or observation depending on the biochemical profile and the clinical status of the patient...

A 24-year-old man was admitted to our Otolaryngology Department following a head and neck CT scan performed for cranial trauma that showed a bulky neoformation in the right parapharyngeal space. Magnetic resonance imaging confirmed the presence of an oval formation with sharp margins and colliquative areas of necrosis involving the right parapharyngeal space. The mass was completely excised by a latero-cervical approach. Based on histological features and immunohistochemical analysis, a diagnosis of embryonal rhabdomyosarcoma of the parapharyngeal space was made...

AIM: To address the hypothesis that young, gonad-intact female mice have improved long-term recovery associated with decreased neuroinflammation compared to male mice. METHODS: Eight to ten week-old male, female, and ovariectomized (OVX) mice underwent closed cranial impact. Gonad-intact female mice were injured only in estrus state. After injury, between group differences were assessed using complementary immunohistochemical staining for microglial cells at 1 h, mRNA polymerase chain reaction for inflammatory markers at 1 h after injury, Rotarod over days 1-7, and water maze on days 28-31 after injury...

Radiation-induced late brain injury consisting of vascular abnormalities, demyelination, white matter necrosis, and cognitive impairment has been described in patients subjected to cranial radiotherapy for brain tumors. Accumulating evidence suggests that various degrees of cognitive deficit can develop after much lower doses of ionizing radiation, as well. The pathophysiological mechanisms underlying these alterations are not elucidated so far. A permanent deficit in neurogenesis, chronic microvascular alterations, and blood-brain barrier dysfunctionality are considered among the main causative factors...

BACKGROUND: Intrinsic brainstem epidermoid cysts are rare, benign, slow growing lesions. Their eloquence preclude complete excision, however subtotal resection will often result in prolonged or sometimes permanent relief of presenting symptoms and signs. We describe an unusual case and review the literature of this pathology in the paediatric population. CASE DESCRIPTION: We report an intra-axial pontine epidermoid cyst in a 2-year-old girl who presented with developmental delay, multiple cranial nerve palsies and pneumonia...

The aim of this study was the evaluation of three localizations for the implantation of a semi-implantable transcutaneous bone conduction device after previous mastoid surgery. This is a retrospective review of electronic datasets of cranial computed tomography studies. The study setting is one tertiary referral center and included 52 consecutive adult patients (60 temporal bones) with a history of mastoid surgery. The intervention was virtual placement of the device with a planning software within the remaining mastoid as well as dorsal of the sigmoid sinus and caudal of the transverse sinus (retrosigmoidal localization) and dorsocranial of the parietomastoid suture and cranial of the transverse sinus (parietal localization)...

Teeth develop through interactions between epithelial and mesenchymal tissues mediated by a signaling network comprised of growth factors and transcription factors However, little is known about how epigenetic modifiers affect signaling pathways and thereby regulate tooth formation. We previously reported that the histone 3 lysine 9 (H3K9) methyltransferase (MTase) G9a is specifically enriched in the tooth mesenchyme during mouse development. In this study, we investigated the functions of G9a in tooth development using G9a conditional knockout (KO) mice...

The degree of disability due to glossopharyngeal neuralgia (GN) refractory to conservative treatments justifies surgical procedures as second-line treatments. Since the first description of this facial pain disorders, many surgical options have been described either via a percutaneous or an open surgical way. Actually, when a neurovascular conflict on root entry zone (REZ) or cisternal portion of the ninth and tenth cranial nerves is identified, microvascular decompression (MVD) is the first surgical option to consider...

Cluster headache is characterized by severe, unilateral headache attacks of orbital, supraorbital or temporal pain lasting 15-180 min accompanied by ipsilateral lacrimation, rhinorrhea and other cranial autonomic manifestations. Cluster headache attacks need fast-acting abortive agents because the pain peaks very quickly; sumatriptan injection is the gold standard acute treatment. First-line preventative drugs include verapamil and carbolithium. Other drugs demonstrated effective in open trials include topiramate, valproic acid, gabapentin and others...

Isabel Bahm, Elias H Barriga, Antonina Frolov, Eric Theveneau, Paul Frankel, Roberto Mayor
A fundamental property of neural crest (NC) migration is Contact inhibition of locomotion (CIL), a process by which cells change their direction of migration upon cell contact. CIL has been proven to be essential for NC migration in amphibian and zebrafish by controlling cell polarity in a cell contact dependent manner. Cell contact during CIL requires the participation of the cell adhesion molecule N-cadherin, which starts to be expressed by NC cells as a consequence of the switch between E- and N-cadherins during epithelial to mesenchymal transition (EMT)...

OBJECTIVE: Intracranial meningiomas are typically benign extracerebral tumors derived from dural arachnoid cells. Predominantly, these tumors are effectively managed surgically, but the prognosis is heavily dependent on tumors' histological heterogeneity and its location. It is known that reproductive and hormonal factors increase the risk for meningioma in adult females, but their prognostic value still remains controversial. This study's aim was to examine possible correlation between tumor location and outcome, and to evaluate prognostic value of the proposed simple tumor localization scale in predicting the management outcome of intracranial meningioma...

PURPOSE: Complete visualization of certain acetabular fractures of posterior wall or column with cranial extension involving superior dome from standard surgical exposures is a challenge. Osteotomy of the greater trochanter has been used to enhance fracture visualization, especially the dome, in posterior and lateral exposures of the acetabulum. It also decreases the need for excessive muscle retraction. The purpose of the study was to investigate the outcome associated with trochanteric flip osteotomy in the management of certain acetabulum fractures...
