BACKGROUND: This study was conducted to determine the incidence of and risk factors associated with the development of radiographic mastoid and middle ear effusions (ME/MEE) in ICU patients. METHODS: Head computed tomography or magnetic resonance images of 300 subjects admitted to the University of Pittsburgh Medical Center neurologic ICU from April 2013 through April 2014 were retrospectively reviewed. Images were reviewed for absent, partial, or complete opacification of the mastoid air cells and middle ear space...

We report a case of a 7-year-old child with a cranial deformity secondary to a craniotomy for an intracranial hematoma. He suffered from an acute epidural hematoma with a lineal fracture of the right temporal bone following a severe head injury. A large question mark-shaped skin flap with the periosteum and temporal muscle was created for a decompressive craniectomy; however, neither the acute epidural hematoma nor brain swelling was severe, and we performed a small craniotomy compared with the skin flap without a decompressive craniectomy...

Pyle's disease is an extremely rare skeletal disorder characterized by a benign course and an autosomal recessive genetic pattern of inheritance. Its causal mutation is still unknown. In the medical literature, fewer than 30 cases have been described to date. We report the case of two female siblings, daughters of consanguineous parents, referred to the radiology department complaining of genu valgum. Laboratory tests showed no other relevant findings. Conventional radiography plain films revealed Erlenmeyer flask deformity in bilateral femorotibial metaphyses, metaphyseal flaring of long bones, and mild sclerosis of the skull base...

BACKGROUND: In cases where autologous bone graft reconstruction is not possible (such as comminuted fractures, bone graft reabsorption, or infection) and the use of synthetic material is required, polymethylmethacrylate (PMMA) use is a safe and efficient solution. Studies comparing the incidence of postoperative complications between autologous and synthetic cranioplasty are heterogeneous, not allowing a conclusion of which is the best material for skull defects reconstruction. Current medical literature lacks prospective well-delineated studies with long-term follow-up that analyze the impact of antibiotic use in PMMA cranial reconstruction of moderate and large defects...

OBJECTIVES: Penetrating gunshot head injuries have a poor prognosis and require prompt care. Brain CT is a routine component of the standard evaluation of head wounds and suspected brain injury. We aimed to investigate the effect of brain CT findings on mortality in gunshot head injury patients who were admitted to our emergency department (ED) from the Syrian Civil War. METHODS: The study group comprised patients who were admitted to the ED with gunshot brain injury...

A 58-year-old woman who had presented for upper gastrointestinal barium examination accidently slipped from the movable bed, and her head became compressed between the end of the bed and the side wall. She suffered massive bleeding from her nose and ear followed by cardiac arrest, and subsequent attempts at cardiopulmonary resuscitation failed. A medicolegal autopsy was performed to reveal the cause of death, as part of the investigation of the accident. During the autopsy, postmortem cerebral CT angiography was carried out by injection of 5% gelatin-barium emulsion as a radiopaque contrast medium into the bilateral common carotid arteries, demonstrating transudation of the contrast medium into the right acoustic meatus and the sphenoidal sinus cavity...

BACKGROUND: Traumatic clival fractures occur with < 0.6% frequency and can be associated with significant neurovascular injuries. The most serious of these injuries is to the basilar artery in which the artery is dissected or is fully occluded resulting in infarction of the brainstem and cerebellum. Among early reports of these injuries, postmortem autopsy showed entrapment, or incarceration, of the basilar artery at the clival fracture site. A literature search revealed 11 cases of entrapment of the basilar artery within a clival fracture...

The severity of seizures presenting to the emergency department ranges from benign to life threatening. There are also a wide number of possible etiologies. Computed tomography (CT) emergency imaging may be required at presentation to elucidate a possible cause and assess signs of intracranial trauma. This case describes a serious seizure episode in a young man while on holiday. A CT brain showed a skull fracture as a consequence of seizure-related head trauma but unexpectedly there were image findings consistent with encephalocraniocutaneous lipomatosis...

Xiaogai Li, Håkan Sandler, Svein Kleiven
Despite recent efforts on the development of finite element (FE) head models of infants, a model capable of capturing head responses under various impact scenarios has not been reported. This is hypothesized partially attributed to the use of simplified linear elastic models for soft tissues of suture, scalp and dura. Orthotropic elastic constants are yet to be determined to incorporate the direction-specific material properties of infant cranial bone due to grain fibres radiating from the ossification centres...

Several types of headholders are routinely used in neurosurgical practice to secure the head in a precise position, providing better security during surgical dissection as well as an absence of eye compression during prone positions. Nevertheless, potentially lethal complications might occur. We performed a review of the literature via PubMed and Google Scholar using the terms "Mayfield skull clamp", "Sugita headholders", "headholder complications" and "skull clamp complications". Twenty-six complications directly related to the use of headholders were identified through 19 papers published from 1981 to 2014: mainly skull fractures with or without a dural laceration (50%), epidural hematomas (23...

Distinguishing between accidental and abusive head trauma in children can be difficult, as there is a lack of baseline data for pediatric cranial fracture patterns. A porcine head model has recently been developed and utilized in a series of studies to investigate the effects of impact energy level, surface type, and constraint condition on cranial fracture patterns. In the current study, an automated pattern recognition method, or a fracture printing interface (FPI), was developed to classify cranial fracture patterns that were associated with different impact scenarios documented in previous experiments...

Skull fracture characteristics are associated with loading conditions (such as the impact point and impact velocity) and could provide indication of abuse or accident-induced head injuries. However, correlations between fracture characteristics and loading conditions in infant and toddler are ill-understood. A simplified computational model representing an infant head was built to simulate skull responses to blunt impacts. The fractures were decided through a first principal strain-based element elimination strategy...

BACKGROUND: Diagnosis and treatment of children with mild traumatic brain injury (mTBI) remain a challenge since initial signs and symptoms do not always indicate the severity of the trauma. Therefore, guidelines regarding the decision upon imaging methods and ambulatory or hospitalized treatment are needed. The goal of our study was to investigate if the standard that was allied from the PECARN rules and is applied in this study can ensure that patients with clinically important brain injury are recognized and leads to outcomes with a low complication rate, a high patient satisfaction and minimal post-concussion syndrome incidence...

INTRODUCTION: Juvenile Pagets disease (JPD), an ultra-rare, debilitating bone disease stemming from unopposed RANKL action due to loss of functional osteoprotegerin (OPG) is caused by recessive mutations in TNFRSF11B. A genotype-phenotype correlation spanning from mild to very severe forms is described. AIM: To describe the complexity of the human phenotype of OPG deficiency in more detail and to investigate heterozygous mutation carriers for clinical signs of JPD...

This study assesses the risk of fractures among children with Tourette syndrome (TS), and identifies the effects of comorbidities and antipsychotics. We randomly sampled the claims data of 1 million enrollees in the National Health Insurance program of Taiwan, and identified 1258 children with TS diagnosed between 2000 and 2010. Additionally, 12,580 children without TS who were frequency matched for sex, age, residential area, parental occupation, and index year were identified for comparison. The children's cases were followed until December 31, 2010, or censored to ascertain incident fractures cases and associations with comorbidities of attention-deficit/hyperactivity disorder (ADHD) or obsessive-compulsive disorder (OCD) and treatments with antipsychotics, antidepressants, or clonidine...

BACKGROUND: Pediatric patients with any severity of traumatic intracranial hemorrhage (tICH) are often admitted to intensive care units (ICUs) for early detection of secondary injury. We hypothesize that there is a subset of these patients with mild injury and tICH for whom ICU care is unnecessary. OBJECTIVES: To quantify tICH frequency and describe disposition and to identify patients at low risk of inpatient critical care intervention (CCI). METHODS: We retrospectively reviewed patients aged 0 to 17 years with tICH at a single level I trauma center from 2008 to 2013...

OBJECTIVE: Detection of vertical root fractures (VRF) in their initial stages is a crucial issue which prevents the propagation of injury to the adjacent supporting structures. Designing a suitable neural network based model could be a useful method to diagnose the VRFs. The aim of this study was to design a probabilistic neural network to diagnose the vertical root fractures in intact and endodontically treated teeth of periapical and CBCT radiographs. Also, we have compared the efficacy of these two imaging techniques in the detection of VRFs...
