    Purpose: To compare the diagnostic information obtained from ultrafast MR imaging with standard MR imaging techniques in pediatric neuroradiology. The goal was to judge whether ultrafast methods can be used to replace standard methods and reduce the need for sedation or general anesthesia as a result of the considerably shorter scan times. Material and Methods: Our prospective study involved 125 patients. Routine clinical imaging was performed along with two ultrafast methods. Single shot fast spin echo (SSFSE) was used to give T2-weighted images and an echo planar imaging (EPI) sequence to provide a T1-weighted images. The ultrafast images were presented to an experienced neuro radiologist who was also given the information present on the initial referral card. These reports based on the ultrafast images were then compared with the formal radiologic report made solely on the basis of the standard imaging. Results: The overall sensitivity and specificity for ultrafast imaging when compared to the reference standard were 78% and 98% with positive and negative predictive values of 98% and 76%. Pathologies characterized by small areas of subtle T2 prolongation were difficult or impossible to see on the ultrafast images but otherwise they provided reliable information. Conclusions: This paper demonstrates that ultrafast MR imaging can diagnose many pediatric intracranial abnormalities as well as standard methods. Anatomic resolution limits its capacity to define subtle developmental anomalies and contrast resolution limitations of the ultrafast methods reduce the detection of pathology characterized by subtle T2 prolongation

    PURPOSE: Current knowledge on the spectrum of the neuroradiological appearance of adult medulloblastoma is sparse. Due to the rarity of the disease, adult patients were generally diagnosed and treated similar to children; however, pediatric and adult medulloblastomas display substantial molecular...... differences that may influence the neuroradiological phenotype. This study therefore aimed at assessment of the neuroradiological spectrum of adult medulloblastoma in comparison to pediatric tumors. METHODS: All available publications on adult medulloblastoma published until June 2013 were screened...... for imaging data on single patients. A total of 109 patients were identified and compared to 118 pediatric patients described in 4 cohorts. RESULTS: The average age of the adult patients was 34.3 years. Most adult medulloblastomas (57.6 %) were localized laterally (vs. 14.4 % in pediatric patients). On T1...

    A group of 23 pediatric patients seropositive for HIV antibody were studied by computed tomography and evaluated neurodevelopmentally. Significant neurodevelopmental delays were found in over 95% of the patients studied. CT findings in six patients were normal and thirteen of 23 (57%) had prominence of the CSF spaces. Less frequent findings included calcifications in the basal ganglia and white matter. Cerebral mass lesions included one case of lymphoma and one case of hemorrhage. The CT findings in the pediatric age group differs from the adult population in that that contrast enhancing inflammatory mass lesions are uncommon.

    The number of medical X-ray imaging procedures is growing exponentially across the globe. Even though the overall benefit from medical X-ray imaging procedures far outweighs any associated risks, it is crucial to take all necessary steps to minimize radiation risks to children without jeopardizing image quality. Among the X-ray imaging studies, except for interventional fluoroscopy procedures, CT studies constitute higher dose and therefore draw considerable scrutiny. A number of technological advances have provided ways for better and safer CT imaging. This article provides an update on the radiation safety of patients and staff and discusses dose optimization in medical X-ray imaging within pediatric neuroradiology. (orig.)

    A retrospective study of 160 pediatric neuroradiological examinations was conducted to determine the efficacy and safety of two sedation regimens (figs. 1, 2). For CT purposes, 150 patients (fig. 3) were orally given monosodium trichlorethyl phosphate syrup (100 mg/kg, with repeat 50 mg/kg if necessary), and for cerebral angiography, 15 patients (fig. 4) were intramuscularly administered a modified D.P.T. cocktail (pentazocine, chlorpromadine, promethazine). Failure rate in the oral syrup group was 6%, and in the D.P.T. group 6.7%. Diagnostic-quality images were obtained in 99.3% and 100%, respectively, of the two groups. There were neither mortality nor significant complications (table 3). It was concluded that each method had proved acceptably safe and effective, and that measures can be taken to further decrease complications and sedation failures. (author)

    Magnetic resonance spectroscopy (MRS) offers a unique, noninvasive approach to assess pediatric neurological abnormalities at microscopic levels by quantifying cellular metabolites. The most widely available MRS method, proton ( 1 H; hydrogen) spectroscopy, is FDA approved for general use and can be ordered by clinicians for pediatric neuroimaging studies if indicated. There are a multitude of both acquisition and post-processing methods that can be used in the implementation of MR spectroscopy. MRS in pediatric neuroimaging is challenging to interpret because of dramatic normal developmental changes that occur in metabolites, particularly in the first year of life. Still, MRS has been proven to provide additional clinically relevant information for several pediatric neurological disease processes such as brain tumors, infectious processes, white matter disorders, and neonatal injury. MRS can also be used as a powerful quantitative research tool. In this article, specific research applications using MRS will be demonstrated in relation to neonatal brain injury and pediatric brain tumor imaging. (orig.)

    Molecular imaging with positron emitting tomography (PET) is widely accepted as an essential part of the diagnosis and evaluation of neoplastic and non-neoplastic disease processes. PET has expanded its role from the research domain into clinical application for oncology, cardiology and neuropsychiatry. More recently, PET is being used as a clinical molecular imaging tool in pediatric neuroimaging. PET is considered an accurate and noninvasive method to study brain activity and to understand pediatric neurological disease processes. In this review, specific examples of the clinical use of PET are given with respect to pediatric neuroimaging. The current use of co-registration of PET with MR imaging is exemplified in regard to pediatric epilepsy. The current use of PET/CT in the evaluation of head and neck lymphoma and pediatric brain tumors is also reviewed. Emerging technologies including PET/MRI and neuroreceptor imaging are discussed.

    The dramatic change in the neuroradiological procedures have been noted after CT scan was introduced in the last several years. Remarkable decreasing numbers of angiographic, pneumoencephalographic and other invasive neuroradiologic studies as well as nuclear brain scan were also found in the pediatric neuroradiology. The authors analyzed the total numbers of these studies performed in the last several years in pediatric neurological/neurosurgical practice in the light of the impact of CT scan especially in the diagnostic procedures and treatments of brain tumor in children. Although the number of these procedures decreased up to 49% in plain skull X-ray, 54% in cerebral angiography, 70% in pneumoencephalography/ventriculography and 79% in nuclear brain scan after CT scan was installed in our results, it is extremely important to renew understanding of those characteristics in each special procedures. Cerebral angiography as well as pneumoencephalography may give the surgeon more precise ideas of the anatomical relationship between the lesion and other normal structures, especially in the posterior fossa tumor in which CT scan occassionally demonstrates only a gross finding. A case with false negative result and another case with a complicated anatomical structure in CT scan were presented. The significance of cerebral angiography and other invasive studies in the diagnosis and follow up of brain tumor in CT scan were discussed.

    With an overall incidence of 10 % of all central nervous system tumors, spinal tumors are relatively rare in children. The majority of these tumors are astrocytomas and ependymomas (70 %) followed by rare non-glial tumor entities, such as gangliogliomas. They can be differentiated into intramedullary, extramedullary intradural and extramedullary extradural tumors according to their occurrence within the anatomical intraspinal compartments. The clinical presentation is generally unspecific. Longer lasting back pain or a gradually worsening scoliosis are often the first signs of the disease. Neurological deficits, such as gait disturbances and paresis often occur after a time delay. In rare cases increased intracranial pressure has been reported. Knowledge concerning potential organ manifestations, resulting complications and typical radiological presentation, especially in magnetic resonance imaging are mandatory for adequate diagnosis and treatment of affected patients. (orig.) [German] Spinale Tumoren umfassen bei Kindern etwa 10 % aller auftretenden Tumoren des Zentralnervensystems (ZNS) und sind damit relativ selten.

Differenziert werden koennen sie nach ihrem Auftreten innerhalb der anatomischen intraspinalen Kompartimente in intra- und extramedullaere sowie intra- und extradurale Tumoren. Ihre klinische Praesentation ist haeufig unspezifisch. Laenger bestehende Rueckenschmerzen oder eine progrediente Skoliose sind oft erste Hinweise auf eine Erkrankung. Neurologische Ausfallerscheinungen wie Gangstoerungen und progrediente Laehmungen treten meist zeitlich verzoegert auf. In Einzelfaellen wird ueber Hirndruckzeichen berichtet. Kenntnisse ueber die moegliche Organmanifestation, resultierende Komplikationen und die typischen radiologischen Befunde v. a. in der MRT sind entscheidend fuer die adaequate Diagnose und Behandlung der betroffenen Patienten.

    Previously at 150 mSv year -1 , the ICRP now recommends limiting the equivalent dose to the eye lens to 20 mSv year -1 . For pediatric interventional neuroradiology, the exposure of the operator's eye lens may be increased by the use of a biplane fluoroscopy system and by the proximity of the physician to the patient. In practice, the efficiency of leaded glasses depends on many factors. This study addresses both aspects. First, the eye lens dose of a neuro-radiologist was measured during 12 procedures using 36 TLDs placed on his surgical cap. Secondly, in order to determine the efficiency of leaded glasses, measurements were carried out by reproducing the clinical conditions. A detector was placed on the left eye of a phantom representing the operator. Four pairs of leaded glasses were selected to test various parameters. During the 12 procedures, an individual dose equivalent Hp(0.07) of 45μSv was obtained for the eye lens closest to the tube. This study shows an eye lens dose to DAP ratio 5 times higher than for procedures performed on adult patients. The eye lens dose might be reduced by a factor of approximately 3 with the use of appropriate leaded glasses. The eye wear model with the most coverage reduces the dose by up to 50% more than the model with the least coverage. The addition of lateral protection increases the attenuation by up to 13% compared with the same model without side protection. (authors)

    During interventional neuroradiology procedures, patients can be exposed to moderate to high levels of radiation. Special considerations are required to protect children, who are generally more sensitive to the short- and long-term detrimental effects of radiation exposure. Estimates of dose to the skin of children from certain interventional procedures have been published elsewhere, but we are not aware of data on dose to the brain or on the long-term risk of cancer from brain radiation. Our goals were to estimate radiation doses to the brain in 50 pediatric patients who had undergone cerebral embolization and to assess their lifetime risks of developing radiation-related brain cancer. Entrance-peak skin dose and various assumptions on conditions of exposure were used as input for dosimetric calculations to estimate the spatial pattern of dose within the brain and the average dose to the whole brain for each child. The average dose and the age of the child at time of exposure were used to estimate the lifetime risk of developing radiation-related brain cancer. Among the 50 patients, average radiation doses to the brain were estimated to vary from 100 mGy to 1,300 mGy if exposed to non-collimated fields and from 20 mGy to 160 mGy for collimated, moving fields. The lifetime risk of developing brain cancer was estimated to be increased by 2% to 80% as a result of the exposure. Given the very small lifetime background risk of brain tumor, the excess number of cases will be small even though the relative increase might be as high as 80%. ALARA principles of collimation and dose optimization are the most effective means to minimize the risk of future radiation-related cancer. (orig.)

    The book is directed at emergency radiologists and neuroradiologists. It aims at providing exhaustive information that will help the reader understand the clinical problems in the full range of neurological emergencies and to select the methodological and technical options that will ensure prompt and effective response and correct interpretation of the clinical findings. The various chapters address the most common neuroradiological emergencies, summarize their fundamental physiopathological features, describe the main semiological and differential diagnostic features, and provide operative suggestions for the selection of the appropriate techniques to be applied in a sequential order. The book addresses the application of state-of-the-art techniques and their implications for clinical practice (particularly the contributions of standard and functional MRI and of spiral and multislice CT). The illustrations provide not only training but also reference material for routine clinical work. (orig.)

    The purpose of this study was two-fold: (a) to measure the dose to the brain using clinical protocols at our institution, and (b) to develop a scanner-independent dosimetry method to estimate brain dose. Radiation dose was measured with a pediatric anthropomorphic phantom and MOSFET detectors. Six current neuroradiology protocols were used: brain, sinuses, facial bones, orbits, temporal bones, and craniofacial areas. Two different CT vendor scanners (scanner A and B) were used. Partial volume correction factors (PVCFs) were determined for the brain to account for differences between point doses measured by the MOSFETs and average organ dose. The CTDI vol and DLP for each protocol were recorded. The dose to the brain (mGy) for scanners A and B was 10.7 and 10.0 for the brain protocol, 7.8 and 3.2 for the sinus, 10.2 and 8.6 for the facial bones, 7.4 and 4.7 for the orbits and 1.6 and 1.9 for the temporal bones, respectively. On scanner A, the craniofacial protocol included a standard and high dose option; the dose measured for these exams was 3.9 and 16.9 mGy, respectively. There was only one craniofacial protocol on scanner B; the brain dose measured on this exam was 4.8 mGy. A linear correlation was found between DLP and brain dose with the conversion factors: 0.049 (R 2 = 0.87), 0.046 (R 2 = 0.89) for scanner A and B, and 0.048 (R 2 = 0.89) for both scanners. The range of dose observed was between 1.8 and 16.9 mGy per scan. This suggests that brain dose estimates may be made from DLP. (paper)

    The development of paediatric neuroradiology is a specific persuasion within neuroradiology and has increased in scope and significance throughout the last ten years. The emergence of computed tomography has altered the indications for types of neuroradiological procedures in infants and children. The sophistication, accuracy, and safety of standard neuroradiological procedures have been increased by the accuracy and safety of computed tomography, particularly in the premature infant. There is a growing need for education and instruction in paediatric neuroradiological techniques and paediatric neuroradiological diseases within the neuroradiological fraternity as a whole. (orig.)

    Deep learning is a form of machine learning using a convolutional neural network architecture that shows tremendous promise for imaging applications. It is increasingly being adapted from its original demonstration in computer vision applications to medical imaging. Because of the high volume and wealth of multimodal imaging information acquired in typical studies, neuroradiology is poised to be an early adopter of deep learning. Compelling deep learning research applications have been demonstrated, and their use is likely to grow rapidly. This review article describes the reasons, outlines the basic methods used to train and test deep learning models, and presents a brief overview of current and potential clinical applications with an emphasis on how they are likely to change future neuroradiology practice. Facility with these methods among neuroimaging researchers and clinicians will be important to channel and harness the vast potential of this new method. © 2018 by American Journal of Neuroradiology.

    The introduction of CT in neuroradiological diagnostics has clearly lowered the interest in nuclear examinations. Frequently, these are carried only out of a lack of CT capacity. Still, some examples are given to show how useful cerebral, bone, and cerebrospinal fluid scintiscanning can be in every day routine diagnostics.

    The use of signs or analogies for interpretation and description of medical images is an old and common practice among radiologists. Comparison of findings with animals, food or objects is not unprecedented and routinely performed. Many signs are quite specific and, in some cases, pathognomonic. Indeed, notwithstanding their degree of specificity, signs may help in the characterization of certain diseases. Several neuroradiological signs have been already described. The authors will present 15 neuroradiology signs in the present essay, approaching their main characteristics, the significance of their role in the clinical practice, as well as their respective imaging findings.

    There are multiple diagnostic criteria for vascular dementia (VaD) that may define different populations. Utilizing the criteria of the National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN) has provided improved consistency in the diagnosis of VaD. The criteria include a table listing brain imaging lesions associated with VaD. The different neuroradiological aspects of the criteria are reviewed based on the imaging data from an ongoing large-scale clinical trial testing a new treatment for VaD. The NINDS-AIREN criteria were applied by a centralized imaging rater to determine eligibility for enrollment in 1,202 patients using brain CT or MRI. Based on the above data set, the neuroradiological features that are associated with VaD and that can result from cerebral small-vessel disease with extensive leukoencephalopathy or lacunae (basal ganglia or frontal white matter), or may be the consequence of single strategically located infarcts or multiple infarcts in large-vessel territories, are illustrated. These features may also be the consequence of global cerebral hypoperfusion, intracerebral hemorrhage, or other mechanisms such as genetically determined arteriopathies. Neuroimaging confirmation of cerebrovascular disease in VaD provides information about the topography and severity of vascular lesions. Neuroimaging may also assist with the differential diagnosis of dementia associated with normal pressure hydrocephalus, chronic subdural hematoma, arteriovenous malformation or tumoral diseases.

    Just a few of interesting topics considered in this chapter are the differentiation of cerebrospinal fluid within the ventricles from that in the subarachnoid spaces by MRI and the practical significance of such distinction; a new contrast medium to be used with MRI; a new classification for an important group of brian tumors in childhood; the validity of CT in permitting accurate demarcation of tumor infiltration within the brain; a reassessment of the accuracy of CT in the diagnosis of pituitary microadenomas (with results that may be rather surprising); the use of ultrasound as an essential aid to the surgeon in exploring masses within or compressing the spinal cord; an assessment of the value of multiplanar reconstruction in the CT diagnosis of lumbar disk disease (again with results that may be surprising); the recognition of a new sign on lateral radiographs of the cervical spine that permits the diagnosis of low odontoid fractures; description of a diagnostic approach based on both conventional and dynamic CT scanning for evaluating and differentiating masses of the neck and deep soft tissues of the face with a remarkable record of positive correlation with surgery and pathology; and the rapidly expanding applications of CT in the diagnosis of temporal bone pathology of many types.

    The digests that follow consider many timely and notable topics, including the contribution of CT to the analysis of injuries of the cervical spine, the relationship of degenerative changes in the cervical vertebrae to the severity of nerve and spinal cord deficit following trauma, the efficacy of intravenous contrast infusion in the demonstration by CT of intraspinal tumors, the role of CT in defining atheromatous and hemorrhagic stenosis of the carotid bifurcation, and the incidence of cerebral infarction in patients with clinically diagnosed transient ischemic attacks. Of special note are studies that demonstrate the usefulness of MRI in defining patchy white matter lesions in the elderly, particularly in the demented aged, and describe the unique appearance on MRI of intravascular thrombosis and intracranial hemorrhage. Reports that correlate the occurrence and relationship of vascular spasm with hydrocephalus in patients with subarachnoid hemorrhage and analyze the clinical significance of lateral displacements of the brain in patients with intracranial masses are particularly worthy of attention. Other studies of interest demonstrate the utility of MRI in assessing normal brain maturation and normal cerebrospinal fluid flow and in defining both normal and abnormal relationships of the cerebellum to the foramen magnum.. In head and neck neoplasms, the remarkable ability to document clinically occult involvement of cervical lymph nodes with CT has added a new dimension to tumor staging. Notable reports document the capability with surface coil MRI of the internal auditory canal and the temporomandibular joint to obtain highly significant diagnostic information not heretofore available with any noninvasive method

    The characteristic neuroradiological features of multiloculated hydrocephalus following neonatal meningitis and ventriculitis in five infants are presented. The role of ventriculography and computerized tomography in detecting multiloculated and enlarged ventricles and paraventricular cavities, as well as complete and incomplete septa, is emphasized for early diagnosis and surgical management. CT scan also provides clues indicating the presence of thin but not visualized septa. It is suggested that post-meningitic hydrocephalus should be repeatedly followed-up for detection of multiloculated transformation. Probably this entity occurs less uncommonly than was thought in the past. The CT scan appears the most helpful and safe procedure for the serial evaluation, but ventriculography may be usefully combined with it in order to plan the most suitable operative approach for fenestration of membranes.

    Neuroradiology always could make best use of subtraction methods, due to the relative immobility and constant shape of the skull. Arterial DSA now has extended the potential uses while reducing the patient's radiation exposure, the contrast medium dosage and osmolarity. The considerable cut-back in time required for invasive examination has reduced the risk of diagnostic and therapeutic measures. The advantages consisting of immediate image display with high contrast resolution in most of the diagnostic tasks counterbalance the disadvantage of low focal resolution of the DSA in neuroradiology. Interventional neuroradiology today cannot do without i.a. DSA. (orig.) [de

    The neuroradiological manifestations of 10 surgically verified craniopharyngiomas are retrospectively studied and compared with those of 8 non-functioning pituitary macroadenomas. The saucer-like appearance of the sella turcica on a craniogram was noted in 2 of the 10 craniopharyngiomas and in 2 of the 8 pituitary adenomas. A ballooning of the sella turcica was observed in one of the 10 craniopharyngiomas and in 5 of the 8 pituitary adenomas. Calcification on CT scan was presented in only 5 craniopharyngiomas. On a plain CT scan, no craniopharyngioma manifested any high-density mass except calcification. Four pituitary adenomas showed a slightly high density, though. A cystic lesion was revealed in all the craniopharyngiomas and in 4 pituitary adenomas. All the craniopharyngiomas except for one intrasellar type and all the pituitary adenomas were enhanced with a contrast medium. The solid portion in one craniopharyngioma and in one pituitary adenoma was high-intensity on T 1 -weighted MRI. The cystic portion in 4 craniopharyngiomas and in 2 pituitary adenomas manifested a high intensity on a T 1 -weighted image. A normal pituitary gland located on the floor of the sella was disclosed in all the craniopharyngiomas on a sagittal T 1 -weighted image; however in all the pituitary adenomas, no normal pituitary gland was found at least not on the floor of the sella. The presence of a normal pituitary gland on the sellar floor on sagittal T 1 -weighted MRI may be a new differential diagnostic point between craniopharyngioma and pituitary macroadenoma. Calcification, cystic formation, and density on a plain CT scan seem to be useful evidence for diagnosis. (author)

    Neuroradiology in the USA was started by the neurosurgeons Harvey Cushing, who personally made the first X-rays used to treat a patient with a neurological disability, and Walter Dandy, who first performed air ventriculography, ventriculoscopy, air encephalography and air myelography. The father of neuroradiology in the USA was Merrill Sosman, Cushing's associate. Modern neuroradiology was introduced into the USA from Europe by Mannie Schechter who was one of the original team of three Chief Editors of Neuroradiology. (orig.)

    Full text: Learning objectives: to make a list of diseases and syndromes which manifest as bilateral symmetric findings on computed tomography and magnetic resonance imaging; to discuss the clinical and radiological differential diagnosis for these diseases; to explain which of these conditions necessitates urgent therapy and when additional studies and laboratory can precise diagnosis. There is symmetry in human body and quite often we compare the affected side to the normal one but in neuroradiology we might have bilateral findings which affected pair structures or corresponding anatomic areas. It is very rare when clinical data prompt diagnosis. Usually clinicians suspect such an involvement but Ct and MRI can reveal symmetric changes and are one of the leading diagnostic tool. The most common location of bilateral findings is basal ganglia and thalamus. There are a number of diseases affecting these structures symmetrically: metabolic and systemic diseases, intoxication, neurodegeneration and vascular conditions, toxoplasmosis, tumors and some infections. Malformations of cortical development and especially bilateral perisylvian polymicrogyria requires not only exact report on the most affected parts but in some cases genetic tests or combination with other clinical symptoms. In the case of herpes simplex encephalitis bilateral temporal involvement is common and this finding very often prompt therapy even before laboratory results. Posterior reversible encephalopathy syndrome (PReS) and some forms of hypoxic ischemic encephalopathy can lead to symmetric changes. In these acute conditions MR plays a crucial role not only in diagnosis but also in monitoring of the therapeutic effect. Patients with neurofibromatosis type 1 or type 2 can demonstrate bilateral optic glioma combined with spinal neurofibroma and bilateral acoustic schwanoma respectively. Mirror-image aneurysm affecting both internal carotid or middle cerebral arteries is an example of symmetry in

    There has been extensive interest in promoting gender equality within radiology, a predominately male field. In this study, our aim was to quantify gender representation in neuroradiology faculty rankings and determine any related factors that may contribute to any such disparity. We evaluated the academic and administrative faculty members of neuroradiology divisions for all on-line listed programs in the US and Canada. After excluding programs that did not fulfill our selection criteria, we generated a short list of 85 US and 8 Canadian programs. We found 465 faculty members who met the inclusion criteria for our study. We used Elsevier's SCOPUS for gathering the data pertaining to the publications, H-index, citations, and tenure of the productivity of each faculty member. Gender disparity was insignificant when analyzing academic ranks. There are more men working in neuroimaging relative to women (χ 2 = 0.46; P = .79). However, gender disparity was highly significant for leadership positions in neuroradiology (χ 2 = 6.76; P = .009). The median H-index was higher among male faculty members (17.5) versus female faculty members (9). Female faculty members have odds of 0.84 compared with male faculty members of having a higher H-index, adjusting for publications, citations, academic ranks, leadership ranks, and interaction between gender and publications and gender and citations (9). Neuroradiology faculty members follow the same male predominance seen in many other specialties of medicine. In this study, issues such as mentoring, role models, opportunities to engage in leadership/research activities, funding opportunities, and mindfulness regarding research productivity are explored. © 2018 by American Journal of Neuroradiology.

    Lumbar and intraneural synovial cysts are uncommon lesions. although their incidence has increased since the introduction of MRI. The authors describe the results of a study comprising 23 patients with synovial cyst (5 lumbar, 19 intraneural). Neuroradiological investigations included CT scan and MRI; however, it was not always possible to diagnose the nature of the lesion. In 18 cases the lesion was removed totally including its capsule; in the other 5 cases it was removed subtotally. Seven of the 23 patients presented a total remission of symptoms/signs, 11 improved and 5 remained unchanged. The importance of treating synovial cysts as radically as possible is discussed together with their most significant clinical and neuroradiological aspects. (author)

    The presence of an intracranial tumor may be suspected or deduced from the clinical history and examination, or it may be discovered incidentally during investigation of another disorder. Once the suggestion is raised, a variety of neuroradiologic techniques are available to define the extent and nature of the lesion. The studies performed may allow a tissue diagnosis to be presumed, may serve as a guide to proposed surgical therapy, or may allow the course of a previously diagnosed lesion to be followed. This chapter discusses the utility of common neuroradiologic techniques and their specific indications in the work-up of intracranial tumors. Emphasis is placed upon tests that are most frequently utilized and have the greatest value

    Magnetic resonance imaging (MRI) has several advantages over computed tomography in the neuroradiological field: it provids biochemical information, images in any plane without bone artifacts, and superior contrast between gray matter and white matter. It is, however, of limited availability because of longer imaging time, poor spatial resolution, and poor visualization of calcification and the bone. In this review, pathophysiology that shows relatively characteristic signal intensity is described, including hemorrhage, fat, protein-rich cyst, calcification, iron, and posterior pituitary gland. The utility and limitation of MRI are discussed in terms of the following diseases and lesion sites: small tumors in the skull base; demyelination of white matter or degenerative disease; cerebral infarction or cerebral ischemic disease; intramedullary lesion; meningeal lesion; and pediatric diseases such as medullary sheath formation and malformation. Finally, recent advance and future perspectives of MRI are presented, focusing on 3-dimensional imaging, MR angiography, fat-suppression MR imaging, MR spectroscopy, intravoxel incoherent motion imaging, imaging time, and spatial resolution.

    Accurate radiographic diagnosis is a cornerstone of the clinical management and outcome prediction of the head-injured patient. New technological advances, such as multi-detector computed tomography (MDCT) scanning and diffusion-weighted magnetic resonance imaging (MRI) have influenced imaging strategy. In this article we review the impact of these developments on the neuroradiological diagnosis of acute head injury. In the acute phase, multi-detector CT has supplanted plain X-ray films of the skull as the initial imaging study of choice. MRI, including fluid-attenuated inversion recovery, gradient echo T2* and diffusion-weighted sequences, is useful in determining the severity of acute brain tissue injury and may help to predict outcome. The role of MRI in showing diffuse axonal injuries is emphasized. We review the different patterns of primary and secondary extra-axial and intra-axial traumatic brain lesions and integrate new insights. Assessment of intracranial hypertension and cerebral herniation are of major clinical importance in patient management. We discuss the issue of pediatric brain trauma and stress the importance of MRI in non-accidental injury. In summary, new developments in imaging technology have advanced our understanding of the pathophysiology of brain trauma and contribute to improving the survival of patients with craniocerebral injuries.

    One of the major problems radiologists face in everyday practice is to decide the correct diagnosis, or at least narrow down the list of possibilities. In this context, indicative evidences (signs) are useful to recognize pathologies, and also to narrow the list of differential diagnoses. Despite classically being described for a single disease, or a closely related family of disorders, most indications are not restricted exclusively to their traditional definition. Therefore, using signs for prognosis requires knowledge of the mechanism of their appearance, and which pathologies they are observed in. In this study, we demonstrate some of the more common and useful neuroradiologic signs with relevant images, and discuss their use in differential diagnosis.

    Vascular interventions are important and helpful for treatment of various pathologies of the head and neck. Interventional neuroradiology of the head and neck includes image-guided biopsies, vessel occlusion, and local chemotherapy. Knowledge of anatomy, functional relationships between intra- and extracranial vessels, and pathology are the basis for therapeutic success. The interventional neuroradiologist is responsible for appropriate selection of patients based on clinical information, indications, and risk assessment. Neuroradiologic imaging, especially CT and MR imaging, and appropriate analysis of angiographic findings help ensure indication for treatment and plan an intervention. Technical equipment, including an angiographic unit, catheters, needles, embolizing materials, and so forth, are important. Knowledge of hemodynamics is relevant to avoid complications and to find the optimal technique for solving the clinical problem. Indications for image-guided biopsies are preverterbal fluid-collections, spinal and paraspinal inflammations and abscesses, deep cervical malignancies, vertebral body, and skull base tumors. Special care should be taken to preserve critical structures in this region, including spinal nerve roots, cervical plexus, main peripheral nerves, and vessels. Indications for vessel occlusion are emergency situations to stop bleeding in vascular lesions (traumatic, malformation, or tumors) by reduction of pressure, preoperative reduction of blood flow to minimize the surgical risk, palliative occlusion of feeding vessels to produce tumor necrosis, or potential curative (or presurgical) occlusion of vascular malformations. Pressure reduction to support normal coagulation, such as epistaxis, in hereditary hemorrhagic telangiectasia can be achieved by proximal vessel occlusion with large particles or platinum coils. Prevention of intraoperative bleeding requires occlusion of the microvascular bed with small particles. Examples of these

    Adaptive statistical iterative reconstruction (ASIR) can decrease image noise, thereby generating CT images of comparable diagnostic quality with less radiation. The purpose of this study is to quantify the effect of systematic use of ASIR versus filtered back projection (FBP) for neuroradiology CT protocols on patients' radiation dose and image quality. We evaluated the effect of ASIR on six types of neuroradiologic CT studies: adult and pediatric unenhanced head CT, adult cervical spine CT, adult cervical and intracranial CT angiography, adult soft tissue neck CT with contrast, and adult lumbar spine CT. For each type of CT study, two groups of 100 consecutive studies were retrospectively reviewed: 100 studies performed with FBP and 100 studies performed with ASIR/FBP blending factor of 40 %/60 % with appropriate noise indices. The weighted volume CT dose index (CTDI{sub vol}), dose-length product (DLP) and noise were recorded. Each study was also reviewed for image quality by two reviewers. Continuous and categorical variables were compared by t test and free permutation test, respectively. For adult unenhanced brain CT, CT cervical myelography, cervical and intracranial CT angiography and lumbar spine CT both CTDI{sub vol} and DLP were lowered by up to 10.9 % (p < 0.001), 17.9 % (p = 0.005), 20.9 % (p < 0.001), and 21.7 % (p = 0.001), respectively, by using ASIR compared with FBP alone. Image quality and noise were similar for both FBP and ASIR. We recommend routine use of iterative reconstruction for neuroradiology CT examinations because this approach affords a significant dose reduction while preserving image quality. (orig.)

    Following the presentation of radiation-induced deterministic effects by some patients undergoing neuroradiological procedures during successive sessions, such as temporary epilation, in the 'Hospital Universitario de Canarias', measurements were made of dose to patients. The maximum dose-area product measured by ionization chamber during these procedures was 39617 cGy.cm{sup 2} in a diagnostic of aneurysm and the maximum dose to the skin measured by thermoluminescent dosemeters (TLDs) was 462.53 mGy. This can justify certain deterministic effects but it is unlikely that the patients will suffer serious effects from this skin dose. Also, measurements were made of effective dose about two usual procedures, embolisation of tumour und embolisation of aneurysm. These procedures were reproduced with an anthropomorphic phantom Rando and doses were measured with TLDs. Effective doses obtained were 3.79 mSv and 4.11 mSv, respectively. The effective dose valued by the program EFFDOSE was less than values measured with TLDs. (author)

    Langerhans cell histiocytosis, previously known as histiocytosis X, is a complex disease consisting of three entities that are all characterized by a proliferation of the Langerhans cell. The clinical course is variable and ranges from a solitary lytic bone or skin lesion with complete remission to a multisystem disorder with possible lethal outcome. The clinical suspicion can be increased based on radiological findings that are important criteria in defining the extent of the disease involvement. A biopsy is often necessary for establishing the final diagnosis. The lytic craniofacial bone lesions are the most common craniospinal abnormality in Langerhans cell histiocytosis. Abnormalities in the hypothalamic-pituitary region are the most frequent manifestations, often accompanied with diabetes insipidus as the presenting symptom. A range of different central nervous system abnormalities can be recognized. It is important to be able to recognize the extensive spectrum of neuroradiological abnormalities in order to arrive at the diagnosis. Neuroimaging plays an even more important role in assessing the response to treatment or possible relapse. (orig.)

    We discussed six cases with dorsal cyst malformations listing their neuroradiological observations and proposed to differentiate between the holosphere and hemisphere as defined by Yokota (1984). The cases were divided into holospheric and hemispheric groups depending on the continuity of their frontal lobe midlines. Cases 1, 2 and 3 were placed in the holospheric group because of their unseparated frontal lobe sbeneath the partially formed anterior interhemispheric fissures. Cases 4, 5 and 6 were grouped in the hemisphere due to the completion of the interhemispheric fissures. There has been a tendency in recent years for most cases of cerebral malformations having an endogenous dorsal cyst with monoventricular configuration to be diagnosed as holoprosencephaly. However, we believe that only patients who have a dorsal cyst in the holospheric brain should be included, and the others in the hemispheric brain, which is capable of completing hemispheric cleavage, should not. Therefore, we emphasize the importance of correctly identifying the holospheric state in the dorsal cyst malformations for diagnosing holoprosencephaly. (author)

    Full Text Available In humans, high-grade gliomas may infiltrate across the corpus callosum resulting in bihemispheric lesions that may have symmetrical, winged-like appearances. This particular tumor manifestation has been coined a ‘butterfly’ glioma (BG. While canine and human gliomas share many neuroradiological and pathological features, the BG morphology has not been previously reported in dogs. Here we describe the magnetic resonance imaging (MRI characteristics of BG in three dogs, and review the potential differential diagnoses based on neuroimaging findings. All dogs presented with generalized seizures and interictal neurological deficits referable to multifocal or diffuse forebrain disease. MRI examinations revealed asymmetrical (2/3 or symmetrical (1/3, bihemispheric intra-axial mass lesions that predominantly affected the frontoparietal lobes and associated with extensive perilesional edema, and involvement of the corpus callosum. The masses displayed heterogeneous T1, T2, and FLAIR signal intensities, variable contrast enhancement (2/3, and mass effect. All tumors demonstrated classical histopathological features of glioblastoma (GBM including glial cell pseudopalisading, serpentine necrosis, microvascular proliferation, as well as invasion of the corpus callosum by neoplastic astrocytes. Although rare, GBM should be considered a differential diagnosis in dogs with MRI evidence of asymmetric or symmetric bilateral, intra-axial cerebral mass lesions with signal characteristics compatible with glioma.

    We report serial neuroradiological studies in a patient with focal cerebritis in the head of the left caudate nucleus. On the day after the onset of symptoms, CT showed an ill-defined low density lesion. The lack of contrast enhancement appeared to be the most important finding for differentiating focal cerebritis from an encapsulated brain abscess or a tumour. MRI two days later revealed the centre of the lesion to be of slightly low intensity on T1-weighted inversion recovery (IR) images and very low intensity on T2-weighted spin echo images, which appeared to correspond to the early cerebritis stage of experimentally induced cerebritis and brain abscess. Ten days after the onset of symptoms, CT revealed a thin ring of enhancement in the head of the caudate nucleus, and a similar small ring was seen in the hypothalamus 16 days after the onset, corresponding to the late cerebritis stage. MRI nine days later revealed ill-defined high signal lesions within the involved area on the T1-weighted IR images. To our knowledge, this is the first published MRI documentation of the early cerebritis stage developing into an encapsulated brain abscess. The mechanisms underlying of these radiographic changes are discussed. (orig.)

Thirty children with CHT, mean age 12.5 ± 1.6 years, 14 (44.8% males, were compared with 38 HC mean age 11.7 ± 1.7 years, 16 (45.7% males. Clinical data were collected from medical charts and questionnaires seeking information on family history, birth and perinatal period events, medications, and overall health history. Neurocognitive function was assessed for global intelligence, visual and verbal memory, and executive functioning using standardized tests. Neuroimaging was performed using 1.5 T magnetic resonance imaging and assessed by two pediatric radiologists. Results. Children with CHT had a similar proportion of incidental findings as did the children in the HC group, at 43.3% and 39.5%, respectively, . Abnormalities of the sellar region were reported in 13.3% of CHT group and 7.9% of HC group, . Other incidental findings included cerebellar ectopia, choroidal fissure and pineal cysts, and multiple increased signal intensity foci. Neuroradiological findings were not associated with clinical and neurocognitive abnormalities. Conclusion. Neuroimaging of children with CHT demonstrated a similar incidence of structural abnormalities as in the healthy population. There is no association between those findings and neurocognitive function.

    Full Text Available PurposeThe aim of this pilot study was to assess the clinical feasibility, diagnostic yield, advantages, and disadvantages of structured reporting for routine MRI-reading in patients with primary diagnosis of intracranial tumors as compared to traditional neuroradiological free text reporting.MethodsA structured MRI reporting template was developed covering pathological, anatomical, and functional aspects in an itemized fashion. Retrospectively, 60 consecutive patients with first diagnosis of an intracranial tumor were selected from the radiology information system/PACS system. Structured reporting was performed by a senior neuroradiologist, blinded to clinical and radiological data. Reporting times were measured per patient. The diagnostic content was compared to free text reporting which was independently performed on the same MRI exams by two other neuroradiologists. The comparisons were categorized per item as: “congruent,” “partially congruent,” “incongruent,” or “not mentioned in free-style report.”ResultsTumor-related items: congruent findings were found for all items (17/17 with congruence rates ranging between 98 and 39% per item. Four items achieved congruence rates ≥90%, 5 items >80%, and 9 items ≥70%. Partially congruent findings were found for all items in up to 50% per item. Incongruent findings were present in 7/17 items in up to 5% per item. Free text reports did not mention 12 of 17 items (range 7–43% per item. Non-tumor-related items, including brain atrophy, microangiopathy, vascular pathologies, and various extracranial pathologies, which were not mentioned in free-text reports between 18 and 85% per item. Mean reporting time for structured reporting was 7:49 min (3:12–17:06 min.ConclusionFirst results showed that expert structured reporting ensured reliable detection of all relevant brain pathologies along with reproducible documentation of all predefined diagnostic items, which was not always the

    An increasing portion of imaging studies are performed by nonradiologists, especially for modalities with the highest relative value units. The aim of this study was to examine the trends in neuroradiologic interpretation among radiologists, neurologists, neurosurgeons, and other specialists within the Medicare population. The number of neuroradiologic studies interpreted by radiologists, neurologists, neurosurgeons, and other specialists in the inpatient, hospital outpatient, and private office settings was determined from the CMS Physician/Supplier Procedure Summary Master Files for 1996 to 2010. Studies billed through professional and global charges were aggregated. Utilization rates and utilization rate compound annual growth rates were computed by specialty and by imaging study. In 1996, radiologists interpreted 4,802,490 (93.7%) CMS neuroradiologic procedures, neurologists 77,312 (1.5%), neurosurgeons 9,825 (0.19%), and other specialists 234,423 (4.6%). In 2010, radiologists interpreted 11,476,376 (93.5%) procedures, neurologists 101,172 (0.8%), neurosurgeons 20,697 (0.17%), and other specialists 680,786 (5.5%). Neurology and neurosurgery lost market share at all sites. Radiology's share increased in the inpatient (from 94.8% to 98.7%) and hospital outpatient (from 95% to 98.7%) settings but decreased in the private office setting (from 88.2% to 73.1%). Lost market share was captured by the other CMS specialty categories, including independent diagnostic testing facilities and multidisciplinary groups, many of which included radiologists. There was marked growth (140%) in neuroradiologic studies between 1996 and 2010 in the Medicare patient population. Radiologists' share of the total neuroradiologic interpretations remained unchanged and constituted 93.5% in 2010. Radiology's market share has shown growth in the inpatient and hospital outpatient sectors but not the private office sector, where independent diagnostic testing facilities, multidisciplinary

    Radiology has attracted the world of art with the esthetic value of its images, and as a new medium for the artistic expression. In order to investigate the links between neuroradiology and art, we examined 12,763 artworks presented in corresponding publications and in Google images on the Internet. The selected artworks were created by 1,964 authors. To give our own contribution to this field, we produced several artful radiological images using the X-ray of 4 cerebral hemispheres, one dissected brain, serial sections of one head and brain, the vascular casts of 2 brains, the magnetic resonance imaging (MRI) scans of one volunteer, and various options in Photoshop. Among the examined artworks, neuroradiological images were used in 129 artworks (1.01%) that were created by 31 artists (1.58%). The artists applied different radiological techniques: X-ray, angiography, computed tomography (CT), multislice CT, MRI, functional MRI, positron emission tomography (PET) or single-photon emission computed tomography (SPECT), either alone or in various combinations. They used the original images, id est (i.e.) radiographs or scans, or their electronic modifications in Photoshop or three-dimensional (3D) software. Some artworks presented the skull, yet others the brain, and still others both, either with or without a head image. The neuroradiological artworks were created as paintings, photographs, digital works and sculptures. Their authors were professional artists, designers, amateurs and radiologists. In conclusion, thanks to the esthetics of some radiological images and the valuable creations of certain artists, neuroradiology has become an important field of contemporary art. (author)

    Overall resident interest in certain subspecialties changes with time. We sought to investigate the latest 6-year trend in interventional radiology (IR) and neuroradiology fellowship applications and how it has affected competitiveness in obtaining a position. We analyzed statistics published by the National Resident Matching Program in Results and Data: Specialties Matching Service from 2008 to 2013. From these data, we calculated the positions per IR applicant (PPIRA) and positions per neuroradiology applicant (PPNRA) for each year. The number of positions per applicant is one way to assess specialty competitiveness on a supply-and-demand basis. A lower PPIRA or PPNRA indicates a more competitive year. PPIRA has decreased every year, from 1.71 to the present 0.84, and contributed to 52 applicants being unmatched in 2013, up from 9 in 2008. Accordingly, the number of unfilled positions has decreased from 86 in 2008 to 8 in 2013. PPNRA waxed and waned from 2008 to 2010 but stabilized at around 1.15 thereafter. The number of unfilled positions has never dropped below 46. The number of unmatched applicants was consistently in the teens, except in 2011, when it increased to 23. Interest in IR fellowship has increased significantly over the past 6 years, whereas interest in neuroradiology fellowships has plateaued. IR fellowships have become increasingly competitive, leading to many unmatched residents. Copyright © 2014 American College of Radiology. Published by Elsevier Inc. All rights reserved.

    To describe the neuroradiologic findings of primary antiphospholipid antibody syndrome (PAPS). During a recent two-year period, abnormally elevated antiphospholipid antibodies were detected in a total of 751 patients. In any cases in which risk factors for stroke were detected - hypertension, diabetes mellitus, hyperlipidemia, smoking, and the presence of SLE or other connective tissue diseases - PAPS was not diagnosed. Neuroradiologic studies were performed in 11 of 32 patients with PAPS. We retrospectively reviewed brain CT (n = 7), MR (n = 8), and cerebral angiography (n = 8) in 11 patients with special attention to the presence of brain parenchymal lesions and cerebral arterial or venous abnormalities. CT or MR findings of PAPS included nonspecific multiple hyper-intensity foci in deep white matter on T2-weighted images (5/11), a large infarct in the territory of the middle cerebral artery (4/11), diffuse cortical atrophy (2/11), focal hemorrhage (2/11), and dural sinus thrombosis (1/11). Angiographic findings were normal (5/8) or reflected either occlusion of a large cerebral artery (2/8) or dural sinus thrombosis (1/8). Neuroradiologic findings of PAPS are nonspecific but in young or middle- aged adults who show the above mentioned CT or MR findings, and in whom risk factors for stroke are not present, the condition should be suspected

    Neuroradiological examinations play a great role today in spinal blood flow disturbances due to spinal vascular disease. This goes for myelography with its new aqueous contrast medium Amipaque as well as for selective spinal arteriography, also with regard to therapeutical approaches (embolisation). Other causes of blood flow disturbances, however - with the exception of growing and displacing processes of the spinal column and spinal canal - cannot be detected by radiological methods or only indirectly; examinations with contrasting agents can only serve for diagnosis by exclusion. The article deals mainly with techniques and findings of examinations for spinal angioma which account for 7 to 11% of growing and displacing processes of the spine. Progress in diagnosis and therapeutical success has been accelerated by technical developments and new contrasting agents as well as by improved surgical techniques.

    Neuroradiological techniques were used to elucidate pathophysiology of recurrent cerebral thrombosis. Twenty-two patients with cerebral thrombosis who suffered a second attack under stable conditions more than 22 days after the initial stroke were studied. Hypertension, diabetes mellitus, and hypercholesterolemia were also seen in 20, 8, and 12 patients, respectively. The patients were divided into three groups according to their symptoms: (I) symptoms differed between the first and second strokes (n=12); (II) initial symptoms were suddenly deteriorated (n=6); and (III) symptoms occurring in groups I and II were seen (n=4). In group I, contralateral hemiparesis or suprabulbar palsy was often associated with the initial hemiparesis. The time of recurrent stroke varied from 4 months to 9 years. CT and MRI showed not only lacunae in both hemispheres, but also deep white-matter ischemia of the centrum semi-ovale. In group II, hemiparesis or visual field defect was deteriorated early after the initial stroke. In addition, neuroimaging revealed that infarction in the posterior cerebral artery was progressed on the contralateral side, or that white matter lesion in the middle artery was enlarged in spite of small lesion in the left cerebral hemisphere. All patients in group III had deterioration of right hemiparesis associated with aphasia. CT, MRI, SPECT, and angiography indicated deep white-matter ischemia caused by main trunk lesions in the left hemisphere. Group III seemed to be equivalent to group II, except for laterality of the lesion. Neuroradiological assessment of the initial stroke may help to predict the mode of recurrence, although pathophysiology of cerebral thrombosis is complicated and varies from patient to patient.

    Pediatric central nervous system (CNS) vascular anomalies include lesions found only in the pediatric population and also the full gamut of vascular lesions found in adults. Pediatric-specific lesions discussed here include infantile hemangioma, vein of Galen malformation and dural sinus malformation. Some CNS vascular lesions that occur in adults, such as arteriovenous malformation, have somewhat distinct manifestations in children, and those are also discussed. Additionally, children with CNS vascular malformations often have associated broader vascular conditions, e.g., PHACES (posterior fossa anomalies, hemangioma, arterial anomalies, cardiac anomalies, eye anomalies and sternal anomalies), hereditary hemorrhagic telangiectasia, and capillary malformation-arteriovenous malformation syndrome (related to the RASA1 mutation). The treatment of pediatric CNS vascular malformations has greatly benefited from advances in endovascular therapy, including technical advances in adult interventional neuroradiology. Dramatic advances in therapy are expected to stem from increased understanding of the genetics and vascular biology that underlie pediatric CNS vascular malformations. (orig.)

    1989-01-01

    Since 1983, we have performed 434 spinal surgery operations. Among them are included 51 cases of lumbar canal stenosis. For these 51 cases, we performed several neuroradiological examinations, such as lumbar plain X-ray, myelography, metrizamide-CT scan (Met-CT) and magnetic resonance imaging (MRI). On myelography, these 51 patients were divided into three types; a complete block type with 29 patients, soy-beans type with 7 patients and strangulation type with 15 patients. Met CT was performed in 37 cases. In both strangulation type and soy-beans type which had been showed through myelography, Met-CT could clearly demonstrate the subarachnoid space, and several structures around the lumbar spinal canal could be clearly identified. In cases which myelography revealed as complete-block type, we identified two subtypes. In the first type subarachnoid space was clearly demonstrated by Met-CT. The second type was comprised of those cases where Met-CT scan could not demonstrate subarachnoid space at all. MRI was performed on 21 patients. MRI clearly showed the anatomical relationship of disc, subarachnoid space, yellow ligament and hypertrophied bony structure. MRI was thus able to bring useful information about lumbar canal stenosis even in cases where Met-CT gave little information due to the lack of metrizamide penetration of the stenotic subarachnoid space.

    International Nuclear Information System (INIS)

    Struffert, T.; Doerfler, A.

    2009-01-01

    Originally aimed at improving standard radiography by providing higher absorption efficiency and a wider dynamic range than available with film-screen and phosphor luminescence, radiography flat detector technology is now widely accepted for neuroangiographic imaging. Especially flat-detector computed tomography (FD-CT), which uses rotational C-arm mounted flat-panel detector technology, is capable of volumetric imaging with a high spatial resolution. As ''angiographic CT'' FD-CT may be helpful in many diagnostic and neurointerventional procedures, e.g. intracranial stenting for cerebrovascular stenoses, stent-assisted coil embolization of wide-necked cerebral aneurysms and embolization of arteriovenous malformations. By providing morphologic, CT-like images of the brain within the angiography suite FD-CT allows rapid visualization of periprocedural hemorrhaging and may thus improve rapid complication management without the need of patient transfer. In addition, myelography and postmyelographic FD-CT imaging can be carried out using a single modality. Spinal interventions, such as kyphoplasty or vertebroplasty might also benefit from FD-CT. Imaging of the temporal bone may also develop into an important field of FD-CT. This paper briefly reviews the technical principles of FD technology and the potential applications in diagnostic and interventional neuroradiology. (orig.) [de

    This article summarizes recent developments in the growing field of interventional neuroradiology for the treatment of acute cerebrovascular disease. We describe the possibilities in endovascular therapy of acute cerebral aneurysms using electrolytically detachable coils combined with trispan neck bridging devices and stent implantation to occlude acute wide neck aneurysms. Techniques and results of local intra-arterial thrombolytic therapy in acute stroke and central retinal artery occlusion are described and we discuss the potential for rapid, large-burden thrombus removal in cases of internal carotid artery thrombosis by rheolytic thrombectomy, percutaneous transluminal angioplasty and stent implantation. Emergency endovascular therapy using the transvenous approach to treat severe intracranial or intraocular hypertension and multifocal haemorrhagic venous infarction due to cerebral sinus thrombosis or dural fistulas is also described. In cases of acute bleeding of head and neck lesions following trauma, tumours after radiotherapy, arteriovenous malformations, epistaxis or from iatrogenic origin, angiography plays a major role in localizing the source of bleeding and occluding the damaged vessel during the same session using the same endovascular approach.

We describe the possibilities in endovascular therapy of acute cerebral aneurysms using electrolytically detachable coils combined with trispan neck bridging devices and stent implantation to occlude acute wide neck aneurysms. Techniques and results of local intra-arterial thrombolytic therapy in acute stroke and central retinal artery occlusion are described and we discuss the potential for rapid, large-burden thrombus removal in cases of internal carotid artery thrombosis by rheolytic thrombectomy, percutaneous transluminal angioplasty and stent implantation. Emergency endovascular therapy using the transvenous approach to treat severe intracranial or intraocular hypertension and multifocal haemorrhagic venous infarction due to cerebral sinus thrombosis or dural fistulas is also described. In cases of acute bleeding of head and neck lesions following trauma, tumours after radiotherapy, arteriovenous malformations, epistaxis or from iatrogenic origin, angiography plays a major role in localizing the source of bleeding and occluding the damaged vessel during the same session using the same endovascular approach.

    Interaction with radiological image data and volume renderings within a sterile environment is a challenging task. Clinically established methods such as joystick control and task delegation can be time-consuming and error-prone and interrupt the workflow. New touchless input modalities may have the potential to overcome these limitations, but their value compared to established methods is unclear. We present a comparative evaluation to analyze the value of two gesture input modalities (Myo Gesture Control Armband and Leap Motion Controller) versus two clinically established methods (task delegation and joystick control). A user study was conducted with ten experienced radiologists by simulating a diagnostic neuroradiological vascular treatment with two frequently used interaction tasks in an experimental operating room. The input modalities were assessed using task completion time, perceived task difficulty, and subjective workload. Overall, the clinically established method of task delegation performed best under the study conditions. In general, gesture control failed to exceed the clinical input approach. However, the Myo Gesture Control Armband showed a potential for simple image selection task. Novel input modalities have the potential to take over single tasks more efficiently than clinically established methods. The results of our user study show the relevance of task characteristics such as task complexity on performance with specific input modalities. Accordingly, future work should consider task characteristics to provide a useful gesture interface for a specific use case instead of an all-in-one solution.

    An outline is given of some of the methodological issues discussed in neuroradiological research on psychiatric illnesses. The strengths and shortcomings of magnetic resonance imaging (MRI) in depicting and quantifying brain structures are described. Temporal lobe anatomy and pathology are easily accessible to MRI, whereas limits on anatomical delineation hamper approaches to frontal lobe study. White matter hyperintense lesions are sensitively depicted by MRI, but specificity is limited. The distinction of vascular and primary degenerative dementia is considerably improved by CT and MRI analysis. Computed tomography (CT) and MRI have enhanced the understanding of treatable organic psychiatric disorders, e.g., normal pressure hydrocephalus. Subcortical and white matter pathology has been replicated in CT and MRI studies of late onset psychiatric disorders, clinical overlap with cerebrovascular disease or neuro degeneration may be of import. Trans cranial sonography findings of brainstem structural change specific to unipolar depression may contribute to the understanding of affective psychoses. Magnetic resonance spectroscopy and functional MRI are likely to stimulate psychiatric research in the future. (author)

    This article outlines artifactual findings commonly encountered in neuroradiologic MRI studies and offers clues to differentiate them from true pathology on the basis of their physical properties. Basic MR physics concepts are used to shed light on the causes of these artifacts. MRI is one of the most commonly used techniques in neuroradiology. Unfortunately, MRI is prone to image distortion and artifacts that can be difficult to identify. Using the provided case illustrations, practical clues, and relevant physical applications, radiologists may devise algorithms to troubleshoot these artifacts.

    A complete image management and communications system has been installed at Georgetown University Hospital (GUH). The network is based on the AT ampersand T CommView System. In the Neuroradiology Division, this network supports a multiscreen workstation with access to multiple imaging modalities such as CT and MRI from both the hospital and a remote imaging center. In addition, the radiologist can access these images from various workstations located throughout the hospital as well as from remote sites such as the home. Among the radiology services supported by the network, neuroradiology has the greatest need for such a system with extensive daily requirements involving the remote imaging center and on-line consultation around the clock. By providing neuroradiology with all available communication links, the radiologist can monitor, diagnose, and consult. The efficiency and effectiveness of the system's capabilities with regard to remote and teleradiology (RVS) operations have been studied for the neuroradiology service. This paper discusses the current clinical acceptance and use, problems in implementation, and ways these difficulties are being surmounted

  7. Quantitative Evaluation of Performance in Interventional Neuroradiology: An Integrated Curriculum Featuring Theoretical and Practical Challenges.

    Full Text Available We sought to develop a standardized curriculum capable of assessing key competencies in Interventional Neuroradiology by the use of models and simulators in an objective, quantitative, and efficient way. In this evaluation we analyzed the associations between the practical experience, theoretical knowledge, and the skills lab performance of interventionalists.We evaluated the endovascular skills of 26 participants of the Advanced Course in Endovascular Interventional Neuroradiology of the European Society of Neuroradiology with a set of three tasks (aneurysm coiling and thrombectomy in a virtual simulator and placement of an intra-aneurysmal flow disruptor in a flow model. Practical experience was assessed by a survey. Participants completed a written and oral examination to evaluate theoretical knowledge. Bivariate and multivariate analyses were performed.In multivariate analysis knowledge of materials and techniques in Interventional Neuroradiology was moderately associated with skills in aneurysm coiling and thrombectomy. Experience in mechanical thrombectomy was moderately associated with thrombectomy skills, while age was negatively associated with thrombectomy skills. We found no significant association between age, sex, or work experience and skills in aneurysm coiling.Our study gives an example of how an integrated curriculum for reasonable and cost-effective assessment of key competences of an interventional neuroradiologist could look. In addition to traditional assessment of theoretical knowledge practical skills are measured by the use of endovascular simulators yielding objective, quantitative, and constructive data for the evaluation of the current performance status of participants as well as the evolution of their technical competency over time.

    The neuroradiological studies (CT, MRI, angiography) in 21 children with perinatal HIV infection were reviewed retrospectively. No patient showed an intracranial mass lesion; after intravenous contrast medium application there was no case with disturbed blood-brain barrier. Common non-specific findings were atrophy and delayed myelination. In 7 cases atrophy was combined with multifocal nearly symmetric white matter lesions, which characteristically spared the U-fibres. Further findings included an intramedullary ring-shaped structure in the cervical cord, an AIDS-associated vasculopathy and symmetric calcifications in the basal ganglia. The spectrum of neuroradiological findings in paediatric AIDS patients differs from that in adults. Knowledge of these age-specific findings is important because the number of HIV-infected children is rising. (orig.)

    Does estimation in interventional neuroradiology can be useful to limit skin radiation injuries. The purpose of this study was to evaluate the role of entrance skin dose (ESD) maps in planning exposure condition optimisation. Thirteen cerebral angiography and five embolisation procedures were monitored, measuring ESD, dose-area product (DAP) and other operational parameters. A transmission ionisation chamber, simultaneously measuring air kerma and DAP, measured dose-related quantities. Data acquisition software collected dosimetric and geometrical data during the interventional procedure and provided a distribution map of ESD on a standard phantom digital image, with maximum value estimation. Values of 88-1710 mGy for maximum skin dose and 16.7-343 Gy cm 2 for DAP were found. These data confirm the possibility of deterministic effects during therapeutic interventional neuroradiological procedures like cerebral embolisation. ESD maps are useful to retrospectively study the exposure characteristics of a procedure and plan patient exposure optimisation. (authors)

    Since the discovery of X-rays, rapid and significant progress has been and continues to be made in imaging techniques, particularly neuroradiology. Milestones along the way included use of contrast agents, digital subtraction angiography, computed tomography, and magnetic resonance imaging. The most recent achievements are visualization of cerebral activation and fiber systems in the brain parenchyma. Application of new contrast agents seems to make imaging at the ''molecular'' level also possible. (orig.) [de

    Covers the normal appearances and complications that may be encountered on neuroradiological examinations following surgery to the head, neck, and spine. Contains numerous images and to-the-point case descriptions. Serves as an invaluable and convenient resource for both neuroradiologists and neurosurgeons. The number of surgical procedures performed on the brain, head, neck, and spine has increased markedly in recent decades. As a result, postoperative changes are being encountered more frequently on neuroradiological examinations and constitute an important part of the workflow. However, the imaging correlates of postsurgical changes can be unfamiliar to neuroradiologists and neurosurgeons and are sometimes difficult to interpret. This book is written by experts in the field and contains an abundance of high-quality images and concise descriptions, which should serve as a useful guide to postsurgical neuroradiology. It will familiarize the reader with the various types of surgical procedure, implanted hardware, and complications. Indeed, this work represents the first text dedicated to the realm of postoperative neuroimaging. Topics reviewed include imaging after facial cosmetic surgery; orbital and oculoplastic surgery; sinus surgery; scalp and cranial surgery; brain tumor treatment; psychosurgery, neurodegenerative surgery, and epilepsy surgery; skull base surgery including transsphenoidal pituitary resection; temporal bone surgery including various ossicular prostheses; orthognathic surgery; surgery of the neck including the types of dissection and flap reconstruction; CSF diversion procedures and devices; spine surgery; and vascular and endovascular neurosurgery.

    Full Text Available Background and Purpose. With the advent of endovascular stroke treatment (EST with mechanical thrombectomy, stroke treatment has also become more challenging. Purpose of this study was to investigate whether a fulltime neuroradiological on-site service and workflow optimization with a structured documentation of the interdisciplinary stroke workflow resulted in improved procedural times. Material and Methods. Procedural times of 322 consecutive patients, who received EST (1 before (n=96 and (2 after (n=126 establishing a 24-hour neuroradiological on-site service as well as (3 after implementation of a structured interdisciplinary workflow documentation (“Stroke Check” (n=100, were analysed. Results. A fulltime neuroradiological on-site service resulted in a nonsignificant improvement of procedural times during out-of-hours admissions (p≥0.204. Working hours and out-of-hours procedural times improved significantly, if additional workflow optimization was realized (p≤0.026. Conclusions. A 24-hour interventional on-site service is a major prerequisite to adequately provide modern reperfusion therapies in patients with acute ischemic stroke. However, simple measures like standardized and focused documentation that affect the entire interdisciplinary pre- and intrahospital stroke rescue chain seem to be important.

    1978-01-01

    Neurological, neuropsychological and neuroradiological studies were performed on 31 cases of the posterior cerebral artery (PCA) occlusion diagnosed by cerebral angiography and/or computed tomography (CT). Neurological examinations revealed visual field defect in 28 cases, contralateral sensory disturbance and hemiparesis in 23 cases and mental syndrome of memory disturbance, disorientation or confusion in 8 cases. CT was done on 17 cases out of 23 cases with contralateral sensory disturbance and hemiparesis. Ten cases of them revealed to have thalamic lesions by CT. In 7 cases which had no evidence of thalamic lesion by CT, 3 cases were highly suspected to have thalamic involvement clinically. The neurological and neuroradiological findings revealed high incidence and its pathomechanism of thalamic lesion in the cases of PCA occlusion. Neuropsychological examinations disclosed pure alexia in 6 cases, cortical blindness in 2 cases and hemispatial agnosia in 2 cases. Four cases with pure alexia were followed their alexic symptoms. Alexic symptoms lasted long in 3 cases. In these cases, collateral flow to the territory of the occlude PCA was hardly visible. One case with a relatively good collateral filling of the occluded PCA, alexic symptoms showed gradual improvement. Two cases with cortical blindness were proven to have bilateral PCA occlusion. In these 2 cases, collateral filling was hardly visible and their symptoms were permanent. The neurological and neuroradiological findings mentioned above suggest that the prognosis of pure alexia and cortical blindness depends largely on the degree of development of collateral circulation to the occluded PCA. Hemispatial agnosia was seen in 2 cases. (author)

    Four patients with leptomeningeal metastases documented by neuroradiological examinations are reported. All had central nervous system or systemic neoplasms and showed clinical signs of carcinomatous meningitis. Gadolinium-enhanced MRI (Gd-MRI) disclosed for each patient pathological foci, allowing delineation of the extent of meningeal disease. Although non-specific, these findings, combined with the clinical context and CSF analysis, may lead to a rapid diagnosis and treatment of carcinomatous meningitis, even when malignant cells are not detected in the cerebrospinal fluid.

    Clinical and neuroradiological studies involving cerebral angiography were conducted in four patients with eclampsia. In three cases (case 1, 2 and 4), neurological focal signs, abnormal low density areas on cranial CT and T{sub 2} high intensity areas on cranial MRI disappeared within a month. But in one case (case 3), cerebral infarction occurred and right hemiparesis and aphasia persisted. Cerebral angiography in the acute phase demonstrated vasospasm in all cases and arterial occlusion in the middle cerebral artery due to vasospasm in case 3. Angiography demonstrated several types of spasms, including diffuse, peripheral and multi local. Furthermore, in some cases, diffuse vasospasms were recognized at the siphon and extracranial portions of the internal carotid artery. In one case (Case 4), segmental vasospasms were detected in the bilateral vertebral arteries. Three to four weeks later, follow-up cerebral angiography was performed in three cases. Cerebral vasospasms had partially or completely recovered. Subarachnoid hemorrhage (SAH) was excluded by lumbar puncture and neuroradiological findings in all cases. We concluded that eclampsia itself causes cerebral vasospasm and that the mechanism of vasospasm is different from that of SAH, since cerebral vasospasm occurred in the extracranial cerebral arteries. We suspected that cerebral vasospasm in eclampsia causes cerebral ischemia, which leads to cytotoxic edema and dysfunction of the blood-brain barrier (BBB) and cerebral autoregulation. With this background, brain edema, especially vasogenic edema, may easily occur and clinical symptoms of eclampsia may appear when the blood pressure rapidly increases. (author).

    Briggs, G.M.; Flynn, P.A.; Worthington, M.; Rennie, I.; McKinstry, C.S.

    2008-01-01

    Aim: To assess the impact on patient management of formal neuroradiology 'second reading' of computed tomography (CT) and magnetic resonance imaging (MRI) images initially interpreted by general radiologists. Materials and methods: Second opinion reports during the calendar year 2004 were compared with the original report and assessed for major or minor discrepancies. A major discrepancy was separated from a minor discrepancy whereby a change in opinion significantly affected patient management. Results: There were 506 second opinions during 2004 given by three consultant neuroradiologists. Incomplete data were found in 141. Forty-one percent were CT images and the remainder MRI. The majority of second opinions were requested by neurologists. Most of the remaining referrals were from neurosurgeons or the primary radiologist. There was a 13% major and a 21% minor discrepancy rate. The remaining 66% were in complete agreement. There was a mixture of overcalls, misinterpretation, and undercalls. There were similar rates of minor and major discrepancies in both CT and MRI. Conclusion: There is a significant major discrepancy rate between specialist neuroradiology second opinion and general radiologists. The benefit of a formal specialist second opinion service is clearly demonstrated; however, it is time-consuming

    Magnetic resonance imaging (MRI) has an important impact in diagnosing primary angiitis of the central nervous system (PACNS). However, neuroradiologic findings may vary immensely, making an easy and definite diagnosis challenging. In this retrospective, single center study, we analyzed neuroradiologic findings of patients with PACNS diagnosed at our hospital between 2009 and 2014. Furthermore, we classified patients according to the affected vessel size and compared imaging characteristics between the subgroups. Thirty-three patients were included (mean age 43 [±15.3] years, 17 females) in this study. Patients with positive angiographic findings were classified as either medium or large vessel PACNS and presented more ischemic lesions (p effect. Twenty-five patients underwent brain biopsy. Patients with medium or large vessel PACNS were less likely to have positive biopsy results. It is essential to differentiate between small and medium/large vessel PACNS since results in MRI, digital subtraction angiography and brain biopsy may differ immensely. Since image quality of MR scanners improves gradually and brain biopsy may often be nonspecific or negative, our results emphasize the importance of MRI/MRA in the diagnosis process of PACNS.

    2003-01-01

    There are few reported cases of nontraumatic dissecting aneurysms of the middle cerebral artery (MCA), and their neuroradiological and clinical features have not been analysed. We looked at these aspects in a collaborative study. We reviewed 13 patients diagnosed as having a dissecting aneurysm of the MCA based on clinical signs and neuroradiological findings in 46 stroke centres between 1995 and 1999. There were four patients who presented with cerebral ischaemia, and nine who presented with bleeding. Of the former group, three were aged less than 15 years. Cerebral angiography showed extensive stenosis and a double lumen of the M1 portion in all four patients. High signal on T1-weighted images around the arterial flow void, due to intramural haematoma, was often seen in the second week. MR angiography showed findings corresponding those of intra-arterial angiography in all four cases. We saw an infarct on CT or MRI in territory of the perforating branches of the M1 segment in all four patients. In the patients presenting with bleeding, pure subarachnoid haemorrhage or a sylvian fissure haematoma was seen on initial CT, and the predominant angiographic finding was dilatation with stenosis, but the site of the lesions was not uniform. A double lumen or intimal flap was seen in about half the cases. Rebleeding occurred within 14 days of the onset in five of the nine patients, with a poor prognosis. (orig.)

    2000-01-01

    Our purpose was to review the neuroradiological features of spinal dysraphism and to correlate them with clinical findings and up-to-date embryological theory. We also aimed to formulate a working classification which might prove useful in clinical practice. We reviewed series of 986 children referred to our Spina Bifida Centre in the past 24 years. There were 353 children with open spinal (OSD) and 633 with closed (skin-covered) spinal (CSD) dysraphism. By far the most common open abnormality was myelomeningocele, and all patients with OSD had a Chiari II malformation. CSD was categorised clinically, depending on the presence of a subcutaneous mass in the back. CSD with a mass mainly consisted of lipomas with dural defects and meningoceles, and accounted for 18.8 % of CSD. CSD without a mass were simple (tight filum terminale, intradural lipoma) or complex (split cord malformations, caudal regression). Our suggested classification is easy to use and to remember and takes into account clinical and MRI features; we have found it useful and reliable when making a preoperative neuroradiological diagnosis in clinical practice.

    Twelve cases of benign extramedullary tumors in the high cervical region and at the foramen magnum were experienced during past five years among eighty all spinal and paraspinal tumors. The diagnosis of masses in this region is very difficult because of the variety of clinical course, symptoms and neurological findings as pointed out by many reporters. Also in our cases, 70 % of the patients complained of the deteriorated motor weakness of the upper or lower extremities on admission, though they had noticed the onset of slight neck or occipital pain a few years ago. Neurological examination on admission clearly showed the symptom of myelopathy except in two cases with a tumor at the foramen magnum and C/sub 1/ level. The percentage of positive findings of plain X-rays was 50 %, that of metrizamide myelography was 92 % and that of IV. e. CT and met. e. CT was 100 %. NMR-CT was performed in 2 cases, and in one of them it was useful in confirming the tumor configuration and extension. Five interesting cases were described mainly from the neuroradiological aspects. Finally the differentiation between meningioma and neurinoma was discussed from the aspects of myelogram, CT and NMR-CT. As already pointed out, it is most important not to forget the existence of tumors in this region when one comes across the confused symptoms, afterwards not to overlook the slight positive neurological and neuroradiological findings.

  13. Early diagnosis of acoustic neuroma by quantitative neurootological and neuroradiological tests

    Every patient with unilateral and sensoneural loss of hearing, independent of vertigo anamnesis or X-rays must be further examined by a vestibular test. Between 1974 and 1980, 80 acoustic neuromas could be diagnosed, including 12 early stage neuromas. This relatively high detection quote of small neuromas is due to a special diagnostical program: All 80 patients with acoustic neuroma had a pathological vestibular result. The positional test turned out to be the most sensitive examination in the early diagnosis of acoustic neuromas and yields a still higher incidence than the caloric test: 95% of the patients with a neurinoma showed a pathological result in the positional test. So every patient suffering from an unidentified unilateral and sensoneural hearing loss combined with a pathological result in the positional test must be further examined by a cisternomeatography or computerized tomography (using air-insufflation). Every fifth of these patients showed unique hints of an acoustic neuroma in the neuroradiological test.

    Wernicke encephalopathy (WE) is an acute neurological disease resulting from dietary thiamine (vitamin B1) deficiency. WE is characterized by changes in consciousness, ocular dysfunction, and ataxia. Neuroradiologic findings usually show symmetric signal intensity alterations in the mammillary bodies, medial thalami, tectal plate, and periaqueductal area. Selective involvement of the cranial nerve nuclei, cerebellum, red nuclei, dentate nuclei, fornix, splenium, cerebral cortex, and basal ganglia characterize nonalcoholic WE patients. Furthermore, symmetric basal ganglia alterations with involvement of the putamen have only been observed in children. The incidence of WE is underestimated in both adult and pediatric patients. Interestingly, the frequency of WE in children appears to be similar to that observed in adults. The prognosis of the disease largely depends on the time from diagnosis to thiamine supplementation. The aim of this pediatric literature review is to provide an update on neuroradiologic findings in children affected by WE in an effort to determine pertinent clinical and imaging findings that can improve the detection and early identification of the disease. A thorough knowledge of the MRI findings of WE will assist in arriving at an early diagnosis, thereby reducing the morbidity and mortality associated with this disease in children. (orig.)

    Diagnostic imaging plays an essential role in pediatric oncology with regard to diagnosis, therapy-planning, and the follow-up of solid tumors. The current imaging standard in pediatric oncology includes a variety of radiological and nuclear medicine imaging modalities depending on the specific tumor entity. The introduction of combined simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI) has opened up new diagnostic options in pediatric oncology. This novel modality combines the excellent anatomical accuracy of MRI with the metabolic information of PET. In initial clinical studies, the technical feasibility and possible diagnostic advantages of combined PET-MRI have been in comparison with alternative imaging techniques. It was shown that a reduction in radiation exposure of up to 70 % is achievable compared with PET-CT. Furthermore, it has been shown that the number of imaging studies necessary can be markedly reduced using combined PET-MRI. Owing to its limited availability, combined PET-MRI is currently not used as a routine procedure. However, this new modality has the potential to become the imaging reference standard in pediatric oncology in the future. This review article summarizes the central aspects of pediatric oncological PET-MRI based on existing literature. Typical pediatric oncological PET-MRI cases are also presented. (orig.)

    Full Text Available Successful practice of pediatric dentistry depends on the establishment of a good relationship between the dentist and the child. Such a relationship is possible only through effective communication. Pediatric dentistry includes both an art and a science component. The focus has been mostly on the technical aspects of our science, and the soft skills we need to develop are often forgotten or neglected. This paper throws light on the communication skills we need to imbibe to be a successful pediatric dentist. A new terminology “Pediatric Dentistese” has been coined similar to motherese, parentese, or baby talk. Since baby talk cannot be applied to all age groups of children, pediatric dentistese has been defined as “the proactive development-based individualized communication between the pediatric dentist and the child which helps to build trust, allay fear, and treat the child effectively and efficiently.”

  18. Diagnostic relevance of high field MRI in clinical neuroradiology: the advantages and challenges of driving a sports car

    International Nuclear Information System (INIS)

    Wattjes, Mike P.; Barkhof, Frederik

    2012-01-01

    High field MRI operating at 3 T is increasingly being used in the field of neuroradiology on the grounds that higher magnetic field strength should theoretically lead to a higher diagnostic accuracy in the diagnosis of several disease entities. This Editorial discusses the exhaustive review by Wardlaw and colleagues of research comparing 3 T MRI with 1.5 T MRI in the field of neuroradiology. Interestingly, the authors found no convincing evidence of improved image quality, diagnostic accuracy, or reduced total examination times using 3 T MRI instead of 1.5 T MRI. These findings are highly relevant since a new generation of high field MRI systems operating at 7 T has recently been introduced. (orig.)

  20. A study of the relationship between peak skin dose and cumulative air kerma in interventional neuroradiology and cardiology

    Neil, S; Padgham, C; Martin, C J

    2010-01-01

    A study of peak skin doses (PSDs) during neuroradiology and cardiology interventional procedures has been carried out using Gafchromic XR-RV2 film. Use of mosaics made from squares held in cling film has allowed doses to the head to be mapped successfully. The displayed cumulative air kerma (CAK) has been calibrated in terms of cumulative entrance surface dose (CESD) and results indicate that this can provide a reliable indicator of the PSD in neuroradiology. Results linking PSD to CESD for interventional cardiology were variable, but CAK is still considered to provide the best option for use as an indicator of potential radiation-induced effects. A CESD exceeding 3 Gy is considered a suitable action level for triggering follow-up of patients in neuroradiology and cardiology for possible skin effects. Application of dose action levels defined in this way would affect 8% of neurological embolisation procedures and 5% of cardiology ablation and multiple stent procedures at the hospitals where the investigations were carried out. A close relationship was observed between CESD and dose-area product (DAP) for particular types of procedure, and DAPs of 200-300 Gy cm 2 could be used as trigger levels where CAK readings were not available. The DAP value would depend on the mean field size and would need to be determined for each application.

    New information technologies offer the possibility of major improvements in the professional education and advanced training of physicians. The web-based, multimedia teaching and learning application Schoolbook has been created and utilized for neuroradiology. Schoolbook is technically based as a content management system and is realized in a LAMP environment. The content is generated with the help of the developed system and stored in a database. The layout is defined by a PHP application, and the webpages are generated from the system. Schoolbook is realized as an authoring tool so that it can be integrated into daily practice. This enables the teacher to autonomously process the content into the web-based application which is used for lectures, seminars and self-study. A multimedia case library is the central building block of Schoolbook for neuroradiology, whereby the learner is provided with original diagnostic and therapeutic data from numerous individual cases. The user can put individual emphasis on key learning points as there are various ways to work with the case histories. Besides the case-based way of teaching and learning, a systematically structured way of dealing with the content is available. eLearning offers various opportunities for teaching and learning in academic and scientific as well as in economic contexts. Web-based applications such as Schoolbook may be beneficial not only for basic university education but also for the realization of international educational programmes such as the European Master of Medical Science with a major in neuroradiology.

    Primary progressive aphasia (PPA) is defined as progressive decline in language for 2 or more years with preservation of activities of daily living and general cognitive functions. Whereas the clinical features of this syndrome have been well documented, the neuroradiological findings have not been studied systematically. We studied 13 patients with PPA retrospectively: 10 underwent CT, 12 MRI and 12 cerebral perfusion studies using 99m Tc-HMPAO SPECT. CT and MR images were scored for focal atrophy by two independent assessors. Initial qualitative assessment of SPECT images was confirmed by quantitative analysis. CY was normal in 5 patients. Focal atrophy, affecting predominantly the left temporal lobe, was seen in 4 of 10 patients on CT, and 10 of 12 on MRI. Atrophy was localised primarily to the superior and middle temporal gyri on MRI. All 12 patients who underwent SPECT had unilateral temporal lobe perfusion defects, in 2 patients of whom MRI was normal. CT is relatively insensitive to focal abnormalities in PPA; MRI and SPECT are the imaging modalities of choice. MRI allows accurate, specific localisation of atrophy with the temporal neocortex. SPECT may reveal a functional decrease in cerebral perfusion prior to establishment of structural change. (orig.)

    Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome is a rare hereditary autosomal-dominant disorder characterized by multiple basal cell carcinomas in young patients, odontogenic keratocysts, palmar or plantar pits, calcification of the falx cerebri and skeletal malformations. This syndrome is due to mutations in PTCH1 (patched homolog 1 da Drosophila), a tumor suppressor gene. Diagnostic criteria were defined by Evans, revised by Kimonis and include major and minor criteria. The authors review in particular the neuroradiological and maxillofacial characteristics of the syndrome. The authors describe the clinical presentation of two children with Gorlin-Goltz syndrome without affected first degree relatives. In both the clinical suspicion of the syndrome is raised by the presence of multiple odontogenic cysts surgically removed. Histopathological exam revealed keratocysts. None of the patients has basal cell carcinomas but both present with skeletal anomalies, namely marked pectus deformity. The absence of major diagnostic criteria like basal cell carcinomas or palmar or plantar pits in young patients delay the early diagnosis and the correct screening for medulloblastoma, basal cell carcinomas and cardiac fibromas. Odontogenic keratocysts are the most consistent clinical finding in Gorlin-Goltz syndrome in the first one or two decades of life. These patients are very sensitive to ionizing radiation, being able to develop basal cell carcinomas and meningiomas. Treatment should accomplish the complete resection of the tumors.

    The purpose of this article is to estimate lens doses using over apron active personal dosemeters in interventional catheterisation laboratories (cardiology IC, neuroradiology IN and radiology IR) and to investigate correlations between occupational lens doses and patient doses. Active electronic personal dosemeters placed over the lead apron were used on a sample of 204 IC procedures, 274 IN and 220 IR (all performed at the same university hospital). Patient dose values (kerma area product) were also recorded to evaluate correlations with occupational doses. Operators used the ceiling-suspended screen in most cases. The median and third quartile values of equivalent dose Hp(10) per procedure measured over the apron for IC, IN and IR resulted, respectively, in 21/67, 19/44 and 24/54 μSv. Patient dose values (median/third quartile) were 75/128, 83/176 and 61/159 Gy cm 2 , respectively. The median ratios for dosemeters worn over the apron by operators ( protected by the ceiling-suspended screen) and patient doses were 0.36; 0.21 and 0.46 μSv Gy -1 cm -2 , respectively. With the conservative approach used (lens doses estimated from the over apron chest dosemeter) we came to the conclusion that more than 800 procedures y -1 and per operator were necessary to reach the new lens dose limit for the three interventional specialties.

    We evaluate the morphology of the carotid plaque using echogram, CT scan and MRI and compare those neuroradiological findings with histological findings of the plaque. We evaluated 14 cases operated with carotid endoarterectomy for carotid stenosis. We estimated the findings of the echogram, enhanced CT scan and black blood MRI (BB MRI), in comparison with the histological findings of the carotid plaque. Echogram, enhanced CT scan and MRI clearly demonstrated the plaque in cervical carotid stenosis. In most cases, echograms could show the plaque, but in some cases could not due to the back shadow caused by plaque calcification. Enhanced CT scan clearly demonstrated the calcification and the neovasculization in plaque. BB MRI clearly showed the carotid plaque. Low-intensity lesions in T1 and T2 weighted images showed hard and fibrous plaque. High-intensity lesions in T1 and T2 weighted images showed soft plaque with lipoprotein and/or hemorrhage. This study demonstrates the potential of a systemic approach to atherosclerotic plaque with enhanced CT scan and BB MRI compared with histological findings of the carotid plaque. These estimations elucidate the growth mechanism of carotid plaque. (author)

    Mitochondrial disorders are a heterogeneous group of disorders affecting energy metabolism that can present at any age with a wide variety of clinical symptoms. We investigated brain magnetic resonance (MR) findings in 40 children with defects of the mitochondrial respiratory chain (MRC) complex and correlated them with the type of MRC defects. Enrolled were 40 children with MRC defects in biochemical enzyme assay of the muscle specimen. Twenty-one children were found to have classical syndromes of mitochondrial disorders and 19 children presented nonspecific mitochondrial encephalomyopathies. Their brain MR imaging findings were retrospectively reviewed and correlated with the biochemical defect in the MRC complex. Children with MRC defects showed various neuroradiologic features on brain MR imaging that resulted from a complex genetic background and a heterogeneous phenotype. Rapid progression of atrophy involving all structures of the brain with variable involvement of deep gray and white matter are the most frequent MR findings in children with MRC defects in both classical syndromes of mitochondrial disorder and nonspecific mitochondrial encephalomyopathies. The type of biochemical defect in the MRC complex enzyme did not correlate with brain MR findings in child patients. (orig.)

    Sensorineural hearing loss (SNHL) is complicated by additional disabilities in about 30% of cases, but the epidemiology of associated disorders, in terms of type, frequency and aetiology is still not clearly defined. Additional disabilities in a deaf child have important consequences in assessing and choosing a therapeutic treatment, in particular when considering cochlear implantation (CI) or hearing aids (HA). The aim of this paper was to evaluate frequency, type and severity of additional neurodevelopmental disabilities in children with profound bilateral sensorineural hearing loss and to investigate the relationship between disability and the etiology of deafness. Eighty children with profound bilateral sensorineural hearing loss (mean age 5.4 years) were investigated by means of a diagnostic protocol including clinical, neurodevelopmental, and audiological procedures together with genetic and neurometabolic tests and neuroradiological investigation by brain MRI. Fifty-five percent of the sample exhibited one or more disabilities in addition to deafness, with cognitive, behavioural-emotional and motor disorders being the most frequent. The risk of additional disabilities varied according to aetiology, with a higher incidence in hereditary syndromic deafness, in cases due to pre-perinatal pathology (in comparison to unknown and hereditary non syndromic forms) and in the presence of major brain abnormalities at MRI. Our results suggest that the aetiology of deafness may be a significant risk indicator for the presence of neuropsychiatric disorders. A multidimensional evaluation, including aetiological, neurodevelopmental and MRI investigation is needed for formulating prognosis and for planning therapeutic intervention, especially in those children candidated to cochlear implant.

    The neuroradiological manifestations of 10 surgically verified craniopharyngiomas are retrospectively studied and compared with those of 8 non-functioning pituitary macroadenomas. The saucer-like appearance of the sella turcica on a craniogram was noted in 2 of the 10 craniopharyngiomas and in 2 of the 8 pituitary adenomas. A ballooning of the sella turcica was observed in one of the 10 craniopharyngiomas and in 5 of the 8 pituitary adenomas. Calcification on CT scan was presented in only 5 craniopharyngiomas. On a plain CT scan, no craniopharyngioma manifested any high-density mass except calcification. Four pituitary adenomas showed a slightly high density, though. A cystic lesion was revealed in all the craniopharyngiomas and in 4 pituitary adenomas. All the craniopharyngiomas except for one intrasellar type and all the pituitary adenomas were enhanced with a contrast medium. The solid portion in one craniopharyngioma and in one pituitary adenoma was high-intensity on T[sub 1]-weighted MRI. The cystic portion in 4 craniopharyngiomas and in 2 pituitary adenomas manifested a high intensity on a T[sub 1]-weighted image. A normal pituitary gland located on the floor of the sella was disclosed in all the craniopharyngiomas on a sagittal T[sub 1]-weighted image; however in all the pituitary adenomas, no normal pituitary gland was found at least not on the floor of the sella. The presence of a normal pituitary gland on the sellar floor on sagittal T[sub 1]-weighted MRI may be a new differential diagnostic point between craniopharyngioma and pituitary macroadenoma. Calcification, cystic formation, and density on a plain CT scan seem to be useful evidence for diagnosis. (author).

    The purpose of this article is to estimate lens doses using over apron active personal dosemeters in interventional catheterisation laboratories (cardiology IC, neuroradiology IN and radiology IR) and to investigate correlations between occupational lens doses and patient doses. Active electronic personal dosemeters placed over the lead apron were used on a sample of 204 IC procedures, 274 IN and 220 IR (all performed at the same university hospital). Patient dose values (kerma area product) were also recorded to evaluate correlations with occupational doses. Operators used the ceiling-suspended screen in most cases. The median and third quartile values of equivalent dose Hp(10) per procedure measured over the apron for IC, IN and IR resulted, respectively, in 21/67, 19/44 and 24/54 µSv. Patient dose values (median/third quartile) were 75/128, 83/176 and 61/159 Gy cm(2), respectively. The median ratios for dosemeters worn over the apron by operators (protected by the ceiling-suspended screen) and patient doses were 0.36; 0.21 and 0.46 µSv Gy(-1) cm(-2), respectively. With the conservative approach used (lens doses estimated from the over apron chest dosemeter) we came to the conclusion that more than 800 procedures y(-1) and per operator were necessary to reach the new lens dose limit for the three interventional specialties. © The Author 2015.

    Aim: To present the neuroradiological and clinical findings of fourth-ventricular meningiomas to increase awareness of this entity. Materials and methods: The computed tomography (CT; n = 5), magnetic resonance imaging (MRI; n = 9) features and clinical presentations of 10 patients with pathologically documented fourth-ventricular meningiomas were retrospectively analysed. Results: All tumours appeared as well-demarcated masses in the fourth ventricle at CT and MRI. The tumour shape was round in eight cases (80%) and irregular in two cases (20%). The CT images of five cases showed predominantly isoattenuation in three cases and high attenuation in two cases, with a mean attenuation value of 52 HU. In addition, calcifications were seen in three cases. At MRI, nine masses were isointense (n = 6) or hypointense (n = 3) to grey matter on T1-weighted images and mildly hyperintense (n = 4), isointense (n = 3), hypointense (n = 1), and of mixed signal intensity (n = 1) on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images. Signal voids were visible in two cases. Enhancement after injection of contrast material was marked homogeneous (n = 5) or heterogeneous (n = 5) on CT or T1-weighted images. Three tumours had mild peritumoural oedema. Three tumours were associated with obstructive hydrocephalus. The pathological subtype of the 10 meningiomas was fibromatous (n = 5), atypical (n = 2), and one each of transitional, psammomatous, and clear-cell type. Conclusion: Although fourth-ventricular meningioma is quite rare, it should be considered in differential diagnosis of neoplasms within the fourth ventricle. The relatively typical radiological appearance, combined the age and sex of patients, can suggest the diagnosis of fourth-ventricular meningioma.

    Full Text Available Krabbe disease is an autosomal recessive neurodegenerative disorder due to a defect of the lysosomal enzyme β-galactocerebrosidase (β-GALC. Depending on the age of onset, the disease is classified into infantile and later-onset forms. We report neuroradiological, neurophysiological and molecular findings in two Greek patients with the infantile form of Krabbe disease. The index patients presented at the age of 3.5 and 6 months, respectively, due to developmental delay. Magnetic resonance imaging (MRI of the first patient’s brain demonstrated signs of leukodystrophy, while nerve conduction velocities (NCVs were significantly decreased. The second patient’s MRI at the age of 4 months was initially normal, but at 18 months demonstrated leukodystrophic alterations as well, whereas NCVs were also significantly delayed. In both patients, a severe decrease in β-GALC, activity supported the diagnosis of Krabbe disease, while the final diagnosis was confirmed by molecular genetic testing. Two homozygous mutations of the GALC gene, the c.411_413delTAA [p.K139del] mutation in the first patient, and the c.749T>C [p.I250T] mutation in the second patient, were identified. At their last follow-up visit at the age of 4 and 6 years, respectively, both patients were bedridden and quadri-plegic, suffering from frequent respiratory tract infections and fed through a gastrostomy. Both mutations found in homozygosity in these two unrelated patients of Greek ancestry, could pinpoint a common origin. Genotyping of patients with Krabbe disease is important, in order to contribute to the creation of a European mutation database and to further study possible genotype-phenotype correlations of the disease.

    To assess technical compliance among neuroradiology attendings and fellows to standard guidelines for lumbar puncture and myelography to minimize procedural complications such as iatrogenic meningitis and spinal headache. We surveyed academic neuroradiology attendings and fellows in the e-mail directory of the Association of Program Directors in Radiology. We queried use of face masks, use of noncutting needles, and dural puncture practices. All data were collected anonymously. A total of 110 survey responses were received: 75 from neuroradiology attendings and 34 from fellows, which represents a 14% response rate from a total of 239 fellows. Forty-seven out of 101 (47%) neuroradiologists do not always wear a face mask during myelograms, and 50 out of 105(48%) neuroradiologists do not always wear a face mask during lumbar punctures, placing patients at risk for iatrogenic meningitis. Ninety-six out of 106 neuroradiologists (91%) use the Quincke cutting needle by default, compared to only 17 out of 109 neuroradiologists (16%) who have ever used noncutting needles proven to reduce spinal headache. Duration of postprocedure bed rest does not influence incidence of spinal headache and may subject patients to unnecessary monitoring. Only 15 out of 109 (14%) neuroradiologists in our study do not prescribe bed rest. There was no statistically significant difference in practice between attendings and fellows. Iatrogenic meningitis and spinal headache are preventable complications of dural puncture that neuroradiologists can minimize by conforming to procedural guidelines. Wearing face masks and using noncutting spinal needles will reduce patient morbidity and lower hospitalization costs associated with procedural complications. Copyright © 2014 AUR.

    2017-01-17

    Cerebral small vessel disease (CSVD) is a common cause of stroke, dementia, and functional decline. In recent years, neuroradiologic correlates of CSVD have been identified. These imaging findings, best characterized on magnetic resonance imaging (MRI), include some combination of white matter hyperintensities, lacunes, cerebral microbleeds, enlarged perivascular spaces, and cerebral atrophy. Though some cohorts have reported that participants with type 2 diabetes mellitus (T2DM), an important risk factor for CSVD, may have a distinct neuroradiologic phenotype, this relationship is not well-characterized. Adults with diabetes mellitus have a two- to threefold higher incidence of ischemic stroke compared to controls and are an increasingly important population given global trends of increasing diabetes prevalence. This study aims to determine if adults with CSVD and T2DM have a distinct neuroradiologic phenotype. A systematic search of the literature will be conducted to find articles that report the MRI features of CSVD in a cohort of participants including those with and without type 2 diabetes mellitus (T2DM). A number of databases will be searched including MEDLINE, Embase, CINAHL, and Web of Science. Proceedings and abstracts from key conferences will also be reviewed and relevant journals hand searched for additional papers. The references from selected papers will be scanned. Screening of potential articles, data extraction, and quality appraisal will be performed in duplicate by independent reviewers. Odds ratios and 95% confidence intervals for the presence versus absence of each neuroradiologic correlate of interest from each included study will be calculated. If sufficient homogeneity exists among studies, a meta-analysis will be performed for each neuroradiologic correlate of CSVD. If heterogeneity of studies precludes data pooling, results will be presented in narrative form. Determining whether a distinct neuroradiologic phenotype of CSVD exists in

    A group of 23 pediatric patients seropositive for HIV antibody were studied by computed tomography and evaluated neurodevelopmentally. Significant neurodevelopmental delays were found in over 95% of the patients studied. CT findings in six patients were normal and thirteen of 23 (57%) had prominence of the CSF spaces. Less frequent findings included calcifications in the basal ganglia and white matter. Cerebral mass lesions included one case of lymphoma and one case of hemorrhage. The CT findings in the pediatric age group differs from the adult population in that that contrast enhancing inflammatory mass lesions are uncommon. (orig.)

    The aim of this review is to define childhood vasculitis and to highlight new causative factors and treatment modalities under the guidance of recently published studies. Childhood vasculitis is difficult to diagnose because of the wide variation in the symptoms and signs. New nomenclature and classification criteria were proposed for the diagnosis of pediatric vasculitis. Recently, progress has been made toward understanding the genetic susceptibility to pediatric vasculitis as it was in other diseases. Various radiological techniques provide great opportunities in establishing the diagnosis of pediatric vasculitis. Mild central nervous system disease can accompany Henoch-Schonlein purpura and can go unnoticed. Antineutrophilic cytoplasmic antibody-associated vasculitis is rare in children. Increased severity of the disease, subglottic stenosis, and renal disease are described more frequently among children. Biological therapies are used with success in children as in adults. Future studies, whose aims are to evaluate treatment responses, prognosis and to design guidelines for activity, and damage index of vasculitis for children are required. Henoch-Schonlein purpura and Kawasaki disease are the most frequent vasculitides of children. Experience from adult studies for treatment and prognosis are usually used because of low incidence of other vasculitides in children. Multicenter studies of pediatric vasculitis should be conducted to detail treatment responses and prognosis in children.

    Tracheotomy refers to a surgical incision made into a trachea. Tracheostomy, on the other hand, refers to a surgical procedure whereby the tracheal lumen is positioned in close proximity to the skin surface. Tracheostomy is an uncommon procedure in the pediatric population. When required tracheostomy is typically performed as an open surgical procedure under general anesthesia with the patient intubated. However, it may need to be performed under local anesthesia or over a rigid bronchoscope in the patient with a precarious airway. Over the past half century, the primary indication for pediatric tracheostomy has shifted from acute infectious airway compromise to the need for prolonged ventilatory support in neurologically compromised children. The surgical technique, choice of tracheostomy tube, and post-operative care requires a nuanced approach in infants and young children. This article will review these topics in a comprehensive fashion. Copyright © 2016 Elsevier Inc. All rights reserved.

    The assessment of cerebral functions has long been the domain of positron-emission tomography and single photon emission computed tomography. The use of rapid imaging sequences and contrast agents enables physiological and pathophysiological cerebral processes to be assessed and monitored by magnetic resonance imaging. Both T1- and T2*-weighted contrast-enhanced fast imaging sequences can be used to assess tissue perfusion, vascularity, and microcirculation by applying models developed in nuclear medicine. The diffusion of water molecules and hemodynamic aspects of the macrovasculature can also be monitored. Functional magnetic resonance (MR) imaging enables the visualization of neuronal function and activity, and MR spectroscopy makes possible the metabolic mapping of lesions and surrounding tissue. The advantages of MR techniques includes their low invasiveness, multiplanar imaging ability, and lack of radiation. This contribution discusses the clinical use of functional MR imaging methods and their role in neuroradiological diseases. Measuring perfusion and diffusion allows detailed insight into the pathophysiology of cerebral ischemia and is already being used routinely in acute ischemic stroke. Dynamic MR angiography enables the hemodynamic assessment of vascular malformations. In CNS neoplasms these imaging techniques can improve lesion characterization and the selecting, planning, and monitoring of therapy. Functional MR imaging techniques have also revolutionized the study of psychiatric illness; however, their clinical utility here is still limited. Initial results in patients with dementia and schizophrenia have provided insight into the pathophysiological changes of these diseases. (orig.)

    Pediatric radiology is an important subsection of diagnostic radiology involving specific difficulties, but unfortunately is quite too often neglected as a subject of further education and training. The book therefore is not intended for specialists in the field, but for radiologists wishing to plunge deeper into the matter of pediatric radiology and to acquire a sound, basic knowledge and information about well-proven modalities, the resulting diagnostic images, and interpretation of results. The book is a compact guide and a helpful source of reference and information required for every-day work, or in special cases. With patients who are babies or children, the challenges are different. The book offers all the information needed, including important experience from pediatric hospital units that may be helpful in diagnostic evaluation, information about specific dissimilarities in anatomy and physiology which affect the imaging results, hints for radiology planning and performance, as well as information about the various techniques and their indication and achievements. The book presents a wide spectrum of informative and annotated images. (orig./CB) [de

    Full Text Available Fibromyalgia (FM is currently defined as chronic widespread pain (CWP with allodynia or hyperalgesia to pressure pain. It is classified as one of the large group of soft-tissue pain syndromes. Pain is the cardinal symptom of FM; however, most patients also experience additional symptoms such as debilitating fatigue, disrupted or non-restorative sleep, functional bowel disturbances, and a variety of neuropsychiatric problems, including cognitive dysfunction, anxiety and depressive symptoms. Its pathogenesis is not entirely understood, although it is currently believed to be the result of a central nervous system (CNS malfunction that increases pain transmission and perception. FMS usually involves females, and in these patients it often makes its first appearance during menopause. But it is often diagnosed both in young as well as elderly individuals. Pediatric FMS is a frustrating condition affecting children and adolescents at a crucial stage of their physical and emotional development. Pediatric FMS is an important differential diagnosis to be considered in the evaluation of children suffering from widespread musculoskeletal pain, and must be differentiated from a spectrum of inflammatory joint disorders such as juvenile idiopathic arthritis (JIA, juvenile ankylosing spondylitis, etc. The management of pediatric FMS is centered on the issues of education, behavioral and cognitive change (with a strong emphasis on physical exercise, and a relatively minor role for pharmacological treatment with medications such as muscle relaxants, analgesics and tricyclic agents.

  19. Sella turcica morphology and the pituitary gland-a new contribution to craniofacial diagnostics based on histology and neuroradiology.

    Kjær, Inger

    2015-02-01

    The present review summarizes two decades of published and unpublished studies on normal and pathological development of sella turcica and pituitary gland in humans. The pathological conditions are studied in known genotype deviations, syndromes, and other malformations. The studies include histological analyses of human prenatal material and profile radiographic analyses of human postnatal material, supplemented in a few cases with neuroradiology. Prenatal and postnatal results are compared. Similarities between prenatal and postnatal deviations in sella turcica morphology were demonstrated. Malformations in the pituitary gland were observed in several cases. For diagnostic purposes, the review distinguishes between deviations in the anterior wall and in the posterior wall of the sella turcica. Deviations in the anterior wall seem to be associated with deviations specifically in the frontonasal developmental field, while deviations in the posterior wall are often connected with malformations in the posterior structures, e.g. the cerebellum. In normal cases, minor variations in morphology are observed. In each pathological case, a specific malformation pattern was observed in sella turcica morphology, varying from mild to severe phenotype. The malformation in the sella turcica/pituitary gland can be associated with a malformation within a developmental field that forms the craniofacial region (frontonasal, maxillary, palatal, and mandibular fields), sometimes also involving the brain stem, thymus, thyroid, and heart (velocardiofacial syndrome). Pathological sella turcica morphology can also be associated with malformations in the cerebellum and larynx (Cri-du-Chat syndrome). This review demonstrates the value of combining profile radiographic diagnostics with neuroradiological diagnostics in cases with malformed sella turcicae. © The Author 2012.

  20. C-arm flat detector computed tomography: the technique and its applications in interventional neuro-radiology

    International Nuclear Information System (INIS)

    Kamran, Mudassar; Nagaraja, Sanjoy; Byrne, James V.

    2010-01-01

    Flat detector computed tomography (FDCT) is an imaging tool that generates three-dimensional (3-D) volumes from data obtained during C-arm rotation using CT-like reconstruction algorithms. The technique is relatively new and, at current levels of performance, lags behind conventional CT in terms of image quality. However, the advantage of its availability in the interventional room has prompted neuro-radiologists to identify clinical settings where its role is uniquely beneficial. We performed a search of the online literature databases to identify studies reporting experience with FDCT in interventional neuro-radiology. The studies were systematically reviewed and their findings grouped according to specific clinical situation addressed. FDCT images allow detection of procedural complications, evaluation of low-radiopacity stents and assessment of endosaccular coil packing in intra-cranial aneurysms. Additional roles are 3-D angiography that provides an accurate depiction of vessel morphology with low concentrations of radiographic contrast media and a potential for perfusion imaging due to its dynamic scanning capability. A single scan combining soft tissue and angiographic examinations reduces radiation dose and examination time. Ongoing developments in flat detector technology and reconstruction algorithms are expected to further enhance its performance and increase this range of applications. FDCT images provide useful information in neuro-interventional setting. If current research confirms its potential for assessing cerebral haemodynamics by perfusion scanning, the combination would redefine it as an invaluable tool for interventional neuro-radiology procedures. This facility and its existing capabilities of parenchymal and angiographic imaging would also extend its use to the triage of acute stroke patients. (orig.)

  1. The Cerefy Neuroradiology Atlas: a Talairach-Tournoux atlas-based tool for analysis of neuroimages available over the internet.

    Nowinski, Wieslaw L; Belov, Dmitry

    2003-09-01

    The article introduces an atlas-assisted method and a tool called the Cerefy Neuroradiology Atlas (CNA), available over the Internet for neuroradiology and human brain mapping. The CNA contains an enhanced, extended, and fully segmented and labeled electronic version of the Talairach-Tournoux brain atlas, including parcelated gyri and Brodmann's areas. To our best knowledge, this is the first online, publicly available application with the Talairach-Tournoux atlas. The process of atlas-assisted neuroimage analysis is done in five steps: image data loading, Talairach landmark setting, atlas normalization, image data exploration and analysis, and result saving. Neuroimage analysis is supported by a near-real-time, atlas-to-data warping based on the Talairach transformation. The CNA runs on multiple platforms; is able to process simultaneously multiple anatomical and functional data sets; and provides functions for a rapid atlas-to-data registration, interactive structure labeling and annotating, and mensuration. It is also empowered with several unique features, including interactive atlas warping facilitating fine tuning of atlas-to-data fit, navigation on the triplanar formed by the image data and the atlas, multiple-images-in-one display with interactive atlas-anatomy-function blending, multiple label display, and saving of labeled and annotated image data. The CNA is useful for fast atlas-assisted analysis of neuroimage data sets. It increases accuracy and reduces time in localization analysis of activation regions; facilitates to communicate the information on the interpreted scans from the neuroradiologist to other clinicians and medical students; increases the neuroradiologist's confidence in terms of anatomy and spatial relationships; and serves as a user-friendly, public domain tool for neuroeducation. At present, more than 700 users from five continents have subscribed to the CNA.

    As the recent outbreak of microcephaly cases caused by Zika virus has been declared a global health emergency, providing assessment guidelines for multidisciplinary teams providing early developmental screening and stimulation to infants with microcephaly is much needed. Thus, the aim of this manuscript is to provide an overview on what is known about neuroradiological aspects and clinical findings in infants with microcephaly caused by Zika virus and to propose a framework for early evaluation of child development. The keywords "Zika virus" and "microcephaly" were searched in PubMed database for articles published from incept to May 2017. These texts were reviewed, and the ones addressing neuroradiological and clinical findings in infants were selected. Recommendations for early assessment were made based on the International Classification of Functionality Disability and Health (ICF) model. The database search yielded 599 publications and 36 were selected. The studies detected microcephaly with diffuse brain malformations and calcifications, ventriculomegaly, optic nerve hypoplasia, macular atrophy, cataracts, impaired visual and hearing function, arthrogryposis, spasticity, hyperreflexia, irritability, tremors, and seizures, but very little is known about early development. Early assessments were described based on the ICF domains (Body Function and Structures, Activities and Participation and Contextual factors). Studies published showed abnormal brain, optic, neurologic and orthopedic findings, but very little is known about other aspects of functioning in infants with microcephaly caused by Zika virus. The biopsychosocial model based on the ICF paradigm provides an adequate framework to describe the condition of the infant with microcephaly receiving rehabilitative efforts to minimize disability. Efforts towards early identification of developmental delays should be taken within the first six months of life. Copyright © 2017 Elsevier Inc. All rights reserved.

    Fibromyalgia is an idiopathic chronic pain syndrome defined by widespread nonarticular musculoskeletal pain and generalized tender points. The syndrome is associated with a constellation of symptoms, including fatigue, nonrefreshing sleep, irritable bowel, and more. Central nervous system sensitization is a major pathophysiologic aspect of fibromyalgia; in addition, various external stimuli such as trauma and stress may contribute to development of the syndrome. Fibromyalgia is most common in midlife, but may be seen at any age. This article reviews the epidemiology, clinical characteristics, etiology, management, and outcome of pediatric fibromyalgia.

    A literature review with 186 references of diagnostic pediatric radiology, a speciality restricted to an age group rather than to an organ system or technique of examination, is presented. In the present chapter topics follow the basic organ system divisions with discussions of special techniques within these divisions. The diagnosis of congenital malformations, infectious diseases and neoplasms are a few of the topics discussed for the head and neck region, the vertebrae, the cardiovascular system, the respiratory system, the gastrointestinal tract, the urinary tract, and the skeleton

    In this article, some of the common and not-so-common neuropediatric disorders were discussed. As in the full-grown animal, abnormalities of the CNS in the pediatric animal patient may be classified according to the type of insult present (eg, malformation, injury, neoplasia, inflammation, or degeneration). To recognize the imaging manifestations of such disorders, an appreciation of normal anatomy, the pathological response of nervous system tissue to insult, and the principles of image interpretation is required. These fundamentals may then be applied to any CNS disease, regardless of frequency and to any animal patient, regardless of age

    Computed tomography has made possible the excellent and basic work having to do with the characteristics of the trachea, its caliber, shape, and length in children. Another group of articles has to do with interventional pediatric radiology. This year there were a number of articles of which only a sample is included, dealing with therapeutic procedures involving drainage of abscesses, angioplasty, nephrostomy, therapeutic embolization, and the removal of esophageal foreign bodies. Obviously, there is no reason to think that techniques developed for the adult may not be applicable to the infant or child; also, there is no reason to believe that processes peculiar to the child should not be amenable to intervention, for instance, use of embolization of hepatic hemangioma and transluminal balloon valvuloplasty for pulmonary valvular stenosis. Among the reports and reviews, the author would add that sonography remains a basic imaging technique in pediatric radiology and each year its application broadens. For example, there is an excellent article having to do with sonography of the neonatal and infant hip and evaluation of the inferior vena cava and the gallbladder. Nuclear medicine continues to play a significant role in diagnosis, which is featured in two articles concerned with problems of the hip

    Pediatric uveitis differs from adult-onset uveitis and is a topic of special interest because of its diagnostic and therapeutic challenges. Children with uveitis are often asymptomatic and the uveitis is often chronic, persistent, recurrent, and resistant to conventional treatment. Anterior uveitis is the most common type of uveitis in children; the prevalence of intermediate, posterior, and panuveitis varies geographically and among ethnic groups. Regarding etiology, most cases of pediatric uveitis are idiopathic but can be due to systemic inflammatory disorders, infections, or a manifestation of masquerade syndrome. Ocular complications include cataracts, hypotony or glaucoma, band keratopathy, synechiae formation, macular edema, optic disc edema, choroidal neovascular membranes, and retinal detachment. These complications are often severe, leading to irreversible structural damage and significant visual disability due to delayed presentation and diagnosis, persistent chronic inflammation from suboptimal treatment, topical and systemic corticosteroid dependence, and delayed initiation of systemic disease‒modifying agents. Treatment for noninfectious uveitis is a stepwise approach starting with corticosteroids. Immunomodulatory therapy should be initiated in cases where quiescence cannot be achieved without steroid dependence. Patients should be monitored regularly for complications of uveitis along with systemic and ocular adverse effects from treatments. The goals are to achieve steroid-free durable remission, to reduce the risk of sight-threatening complications from the uncontrolled ocular inflammation, and to avoid the impact of lifelong burden of visual loss on the child and their family. Multidisciplinary management will ensure holistic care of affected children and improve the support for their families. Copyright 2018 Asia-Pacific Academy of Ophthalmology.

  8. Trends in performance indicators of neuroimaging anatomy research publications: a bibliometric study of major neuroradiology journal output over four decades based on web of science database.

    Quantitative, qualitative, and innovative application of bibliometric research performance indicators to anatomy and radiology research and education can enhance cross-fertilization between the two disciplines. We aim to use these indicators to identify long-term trends in dissemination of publications in neuroimaging anatomy (including both productivity and citation rates), which has subjectively waned in prestige during recent years. We examined publications over the last 40 years in two neuroradiological journals, AJNR and Neuroradiology, and selected and categorized all neuroimaging anatomy research articles according to theme and type. We studied trends in their citation activity over time, and mathematically analyzed these trends for 1977, 1987, and 1997 publications. We created a novel metric, "citation half-life at 10 years postpublication" (CHL-10), and used this to examine trends in the skew of citation numbers for anatomy articles each year. We identified 367 anatomy articles amongst a total of 18,110 in these journals: 74.2% were original articles, with study of normal anatomy being the commonest theme (46.7%). We recorded a mean of 18.03 citations for each anatomy article, 35% higher than for general neuroradiology articles. Graphs summarizing the rise (upslope) in citation rates after publication revealed similar trends spanning two decades. CHL-10 trends demonstrated that more recently published anatomy articles were likely to take longer to reach peak citation rate. Bibliometric analysis suggests that anatomical research in neuroradiology is not languishing. This novel analytical approach can be applied to other aspects of neuroimaging research, and within other subspecialties in radiology and anatomy, and also to foster anatomical education. © 2014 Wiley Periodicals, Inc.

    A recent study found that an earlier age of first exposure (AFE) to tackle football was associated with long-term neurocognitive impairment in retired National Football League (NFL) players. To assess the association between years of exposure to pre-high school football (PreYOE) and neuroradiological, neurological, and neuropsychological outcome measures in a different sample of retired NFL players. Cross-sectional study; Level of evidence, 3. Forty-five former NFL players were included in this study. All participants prospectively completed extensive history taking, a neurological examination, brain magnetic resonance imaging, and a comprehensive battery of neuropsychological tests. To measure the associations between PreYOE and these outcome measures, multiple regression models were utilized while controlling for several covariates. After applying a Bonferroni correction for multiple comparisons, none of the neurological, neuroradiological, or neuropsychological outcome measures yielded a significant relationship with PreYOE. A second Bonferroni-corrected analysis of a subset of these athletes with self-reported learning disability yielded no significant relationships on paper-and-pencil neurocognitive tests but did result in a significant association between learning disability and computerized indices of visual motor speed and reaction time. The current study failed to replicate the results of a prior study, which concluded that an earlier AFE to tackle football might result in long-term neurocognitive deficits. In 45 retired NFL athletes, there were no associations between PreYOE and neuroradiological, neurological, and neuropsychological outcome measures. © 2016 The Author(s).

    Full Text Available Pediatric esophagogastroduodenoscopy (EGD has become an established diagnostic and therapeutic modality in pediatric gastroenterology. Effective sedation strategies have been adopted to improve patient tolerance during pediatric EGD. For children, safety is a fundamental consideration during this procedure as they are at a higher risk of severe adverse events from procedural sedation compared to adults. Therefore, a detailed risk evaluation is required prior to the procedure, and practitioners should be aware of the benefits and risks associated with sedation regimens during pediatric EGD. In addition, pediatric advanced life support by endoscopists or immediate intervention by anesthesiologists should be available in the event that severe adverse events occur during pediatric EGD.

    Pediatric neurocritical care is an emerging multidisciplinary field of medicine and a new frontier in pediatric critical care and pediatric neurology. Central to pediatric neurocritical care is the goal of improving outcomes in critically ill pediatric patients with neurological illness or injury and limiting secondary brain injury through optimal critical care delivery and the support of brain function. There is a pressing need for evidence based guidelines in pediatric neurocritical care, notably in pediatric traumatic brain injury and pediatric stroke. These diseases have distinct clinical and pathophysiological features that distinguish them from their adult counterparts and prevent the direct translation of the adult experience to pediatric patients. Increased attention is also being paid to the broader application of neuromonitoring and neuroprotective strategies in the pediatric intensive care unit, in both primary neurological and primary non-neurological disease states. Although much can be learned from the adult experience, there are important differences in the critically ill pediatric population and in the circumstances that surround the emergence of neurocritical care in pediatrics.

    The use of DSC-MR imaging in pediatric neuroradiology is gradually growing. However, the number of studies listed in the literature remains limited. We propose to assess the perfusion and permeability parameters in pediatric brain tumor grading. Thirty children with a brain tumor having benefited from a DSC-MR perfusion sequence have been retrospectively explored. Relative CBF and CBV were computed on the ROI with the largest lesion coverage. Assessment of the lesion's permeability was also performed through the semi-quantitative PSR parameter and the K2 model-based parameter on the whole-lesion ROI and a reduced ROI drawn on the permeability maps. A statistical comparison of high- and low-grade groups (HG, LG) as well as a ROC analysis was performed on the histogram-based parameters. Our results showed a statistically significant difference between LG and HG groups for mean rCBV (p < 10{sup -3}), rCBF (p < 10{sup -3}), and for PSR (p = 0.03) but not for the K2 factor (p = 0.5). However, the ratio K2/PSR was shown to be a strong discriminating factor between the two groups of lesions (p < 10{sup -3}). For rCBV and rCBF indicators, high values of ROC AUC were obtained (> 0.9) and mean value thresholds were observed at 1.07 and 1.03, respectively. For K2/PSR in the reduced area, AUC was also superior to 0.9. The implementation of a dynamic T2* perfusion sequence provided reliable results using an objective whole-lesion ROI. Perfusion parameters as well as a new permeability indicator could efficiently discriminate high-grade from low-grade lesions in the pediatric population. (orig.)

    Over the last decade interventional neuroradiology (NR) has become the mainstay of managing cerebral aneurysms. The aim of our study was to review our growing experiences with interventional NR and quantify morbidity and mortality associated with these procedures. The electronic medical records of all patients admitted to the Gold Coast (University) Hospital Intensive Care Unit following subarachnoid haemorrhage (SAH) or elective interventional NR management of cerebral aneurysms between January 2012 and December 2014 were retrieved. Primary outcomes of interest were death, thromboembolic and haemorrhagic events during hospital admission. One hundred and fifty-two patients underwent interventional NR procedures for cerebral aneurysms. This consisted of 92 (60.5%) elective cases and 60 (39.5%) emergency cases following SAH. The all-cause mortality rate and the rate of thromboembolic and haemorrhagic events for the entire cohort were 5.9%, 11.2% and 7.2% respectively. Intra-procedural complications occurred in 6.6% of the entire cohort. Median length of follow-up was 448 days, with 91.6% of the entire cohort followed up. At follow-up, 64.1% of patients had no neurological deficits, 29% had mild non-specific deficits and 6.9% had significant disability. Interventional NR represents the primary treatment modality for all patients presenting to our service with cerebral aneurysm. Our results are encouraging and are comparable to published data in the international literature. Reducing the burden of thromboembolism in patients undergoing endovascular treatment of their aneurysmal disease is our main research focus currently, and we aim to improve outcomes for this patient group. © 2017 The Royal Australian and New Zealand College of Radiologists.

  7. Study of the clinical and the neuroradiological findings in multi-infarct dementia and Alzheimer type dementia

    Endo, Riuko [Tokyo Women' s Medical Coll. (Japan)

    1989-06-01

    In forty patients with dementia, a comparison of the clinical and the neuroradiological findings between 15 Alzheimer type dementia (ATD) and 21 multi-infarct dementia (MID) were made. MID had significantly (p<0.01) higher Hachinski's Ischemic Score (HIS) (mean +-S.D., 9.7+-1.8) compared with ATD (3.6+-1.5). The HIS was a useful diagnostic aid in differential diagnosis between the two groups. MID significantly (p<0.01) had cerebrovascular risk factors such as hypertension, diabetes mellitus and increase of platelet aggregation. The morphometric analysis of the ratios of the ventricular dilatation, the cortical atrophy, and the white matter changes was performed on the CT scan and the magnetic resonance imaging. This was the first time the method of having the cortical atrophy analyzed by the ratio of the area of the sylvian sulci and the area of the whole brain had been used. It was found that the degrees of the ventricular dilatation, the cortical atrophy, and the white matter changes were more increased in MID than in ATD (p<0.01{similar to}0.05). In ATD, there was a positive correlation between Hasegawa's Dementia Scale and both the ratios of the ventricular dilatation, and the cortical atrophy (r=-0.62, p<0.05, r=-0.63, p<0.05, respectively). Also a comparative study between MID and 9 patients with multiple infarction, without dementia (MI). MID had the mean infarct numbers of 6.5+-2.5, and MI had 4.1+-2.2. The white matter changes were more increased in MID than MI (p<0.05). The incidence of the dementia was significantly higher in cases with left lenticular nucleus (p<0.01) or main lesions of the white matter in the left frontal lobe (p<0.05), and in cases with bilateral lenticular nucleus (p<0.01), compared to cases without lesions.

  8. Age Limit of Pediatrics.

    Science.gov (United States)

    Hardin, Amy Peykoff; Hackell, Jesse M

    2017-09-01

    Pediatrics is a multifaceted specialty that encompasses children's physical, psychosocial, developmental, and mental health. Pediatric care may begin periconceptionally and continues through gestation, infancy, childhood, adolescence, and young adulthood. Although adolescence and young adulthood are recognizable phases of life, an upper age limit is not easily demarcated and varies depending on the individual patient. The establishment of arbitrary age limits on pediatric care by health care providers should be discouraged. The decision to continue care with a pediatrician or pediatric medical or surgical subspecialist should be made solely by the patient (and family, when appropriate) and the physician and must take into account the physical and psychosocial needs of the patient and the abilities of the pediatric provider to meet these needs.

    Neuroblastoma (NB) is the most frequent indication for extracranial pediatric radiotherapy. As long-term survival of high-risk localized NB has greatly improved, we reviewed treatment-related late toxicities in pediatric patients who received postoperative radiotherapy (RT) for localized NB within two French prospective clinical trials: NB90 and NB94. From 1990-2000, 610 children were enrolled. Among these, 35 were treated with induction chemotherapy, surgery, and RT. The recommended RT dose was 24 Gy at ≤ 2 years, 34 Gy at > 2 years, ± a 5 Gy boost in both age groups. The 22 patients still alive after 5 years were analyzed. The median follow-up time was 14 years (range 5-21 years). Late effects after therapy occurred in 73 % of patients (16/22), within the RT field for 50 % (11/22). The most frequent in-field effects were musculoskeletal abnormalities (n = 7) that occurred only with doses > 31 Gy/1.5 Gy fraction (p = 0.037). Other effects were endocrine in 3 patients and second malignancies in 2 patients. Four patients presented with multiple in-field late effects only with doses > 31 Gy. After a median follow-up of 14 years, late effects with multimodality treatment were frequent. The most frequent effects were musculoskeletal abnormalities and the threshold for their occurrence was 31 Gy. (orig.)

    Endo, Riuko

    1989-01-01

    In forty patients with dementia, a comparison of the clinical and the neuroradiological findings between 15 Alzheimer type dementia (ATD) and 21 multi-infarct dementia (MID) were made. MID had significantly (p<0.01) higher Hachinski's Ischemic Score (HIS) (mean ±S.D., 9.7±1.8) compared with ATD (3.6±1.5). The HIS was a useful diagnostic aid in differential diagnosis between the two groups. MID significantly (p<0.01) had cerebrovascular risk factors such as hypertension, diabetes mellitus and increase of platelet aggregation. The morphometric analysis of the ratios of the ventricular dilatation, the cortical atrophy, and the white matter changes was performed on the CT scan and the magnetic resonance imaging. This was the first time the method of having the cortical atrophy analyzed by the ratio of the area of the sylvian sulci and the area of the whole brain had been used. It was found that the degrees of the ventricular dilatation, the cortical atrophy, and the white matter changes were more increased in MID than in ATD (p<0.01∼0.05). In ATD, there was a positive correlation between Hasegawa's Dementia Scale and both the ratios of the ventricular dilatation, and the cortical atrophy (r=-0.62, p<0.05, r=-0.63, p<0.05, respectively). Also a comparative study between MID and 9 patients with multiple infarction, without dementia (MI). MID had the mean infarct numbers of 6.5±2.5, and MI had 4.1±2.2. The white matter changes were more increased in MID than MI (p<0.05). The incidence of the dementia was significantly higher in cases with left lenticular nucleus (p<0.01) or main lesions of the white matter in the left frontal lobe (p<0.05), and in cases with bilateral lenticular nucleus (p<0.01), compared to cases without lesions.

    2002-01-01

    To assess the computed tomography (CT) and magnetic resonance (MR) findings in MELAS syndrome (mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes) and their contribution to the diagnosis of this entity. We present three patients in which a diagnosis of MELAS syndrome was confirmed by muscle biopsy. CT revealed pathological findings in two patients: bilateral calcifications in the basal nuclei in one and low-attenuation lesions in occipital lobes in the other. Initial or follow-up MR demonstrated pathological findings highly suggestive of MELAS syndrome in all the patients. They consisted of hyperintense lesions in T2-weighted images, located predominantly in the cortex of occipital and parietal lobes. Cerebellar atrophy was also observed in two patients. The clinical signs varied, but epileptic seizures, headache, vomiting, ataxia, muscle weakness and pyramidal involvement were among the major ones. Only one patient presented high lactic acid levels, and in two, the initial muscle biopsy was not conclusive enough to provide the definitive diagnosis. CT and, especially, MR are useful tools in the diagnosis of MELAS syndrome, particularly in those cases in which initial negative laboratory and histological results make diagnosis difficult.

    2017-08-01

    Despite increasing popularity of minimal-invasive techniques in the pediatric population, their use in diagnosis and management of pediatric malignancy is still debated. Moreover, there is limited evidence to clarify this controversy due to low incidence of each individual type of pediatric tumor, huge diversity of the disease entity, heterogeneity of surgical technique, and lack of well-designed studies on pediatric oncologic minimal-invasive surgery. However, a rapid development of medical instruments and technologies accelerated the current trend toward less invasive surgery, including oncologic endosurgery. The aim of this article is to review current literatures about the application of the minimal-invasive approach for pediatric tumors and to give an overview of the current status, indications, individual techniques, and future perspectives.

    Social pediatrics teaches pediatric residents how to understand disease within their patients' social, environmental and political contexts. It's an essential component of pediatric residency training; however there is very little literature that addresses how such a broad-ranging topic can be taught effectively. The aim of this study was to determine and characterize social pediatric education in our pediatric residency training in order to identify strengths and gaps. A social pediatrics curriculum map was developed, attending to 3 different dimensions: (1) the intended curriculum as prescribed by the Objectives of Training for Pediatrics of the Royal College of Physicians and Surgeons of Canada (RCPSC), (2) the formal curriculum defined by rotation-specific learning objectives, and (3) the informal/hidden curriculum as reflected in resident and teacher experiences and perceptions. Forty-one social pediatric learning objectives were extracted from the RCPSC Objectives of Training for Pediatrics, most were listed in the Medical Expert (51%) and Health Advocate competencies (24%). Almost all RCPSC social pediatric learning objectives were identified in more than one rotation and/or seminar. Adolescent Medicine (29.2%), Pediatric Ambulatory Medicine (26.2%) and Developmental Pediatrics (25%) listed the highest proportion of social pediatric learning objectives. Four (10%) RCPSC social pediatric objectives were not explicitly named within learning objectives of the formal curriculum. The informal curriculum revealed that both teachers and residents viewed social pediatrics as integral to all clinical encounters. Perceived barriers to teaching and learning of social pediatrics included time constraints, particularly in a tertiary care environment, and the value of social pediatrics relative to medical expert knowledge. Despite the lack of an explicit thematic presentation of social pediatric learning objectives by the Royal College and residency training program

  6. Pediatric maxillary fractures.

    2011-07-01

    Pediatric craniofacial structures differ from those of adults in many ways. Because of these differences, management of pediatric craniofacial fractures is not the same as those in adults. The most important differences that have clinical relevance are the mechanical properties, craniofacial anatomy, healing capacity, and dental morphology. This article will review these key differences and the management of pediatric maxillary fractures. From the mechanical properties' perspective, pediatric bones are much more resilient than adult bones; as such, they undergo plastic deformation and ductile failure. From the gross anatomic perspective, the relative proportion of the cranial to facial structures is much larger for the pediatric patients and the sinuses are not yet developed. The differences related to dentition and dental development are more conical crowns, larger interdental spaces, and presence of permanent tooth buds in the pediatric population. The fracture pattern, as a result of all the above, does not follow the classic Le Fort types. The maxillomandibular fixation may require circum-mandibular wires, drop wires, or Ivy loops. Interfragmentary ligatures using absorbable sutures play a much greater role in these patients. The use of plates and screws should take into consideration the future development with respect to growth centers and the location of the permanent tooth buds. Pediatric maxillary fractures are not common, require different treatments, and enjoy better long-term outcomes.

    2011-10-01

    Despite the extensive use of robotics in the adult population, the use of robotics in pediatrics has not been well accepted. There is still a lack of awareness from pediatric surgeons on how to use the robotic equipment, its advantages and indications. Benefit is still controversial. Dexterity and better visualization of the surgical field are one of the strong values. Conversely, cost and a lack of small instruments prevent the use of robotics in the smaller patients. The aim of this manuscript is to present the controversies about the use of robotics in pediatric surgery.

    Pediatric emergence agitation/delirium (ED) is a cluster of behaviors seen in the early postanesthetic period with negative emotional consequences for families and increased utilization of healthcare resources. Many studies have looked at identifying risk factors for ED and at pharmacologic regimens to prevent ED. There are few published reports on treatment options and efficacy for established ED episodes, and essentially no data concerning current practice in the treatment of ED. We sought to elicit the experience and opinions of Canadian Pediatric Anesthesiologists on the incidence of ED in their practice, definitions and diagnostic criteria, preventative strategies, treatments, and their perceived efficacy. A web-based survey was sent to pediatric anesthesiologists working at academic health science centers across Canada. The participants were selected based on being members of the Canadian Pediatric Anesthesia Society (CPAS), which represents the subspecialty in Canada. All members of CPAS who had e-mail contact information available in the membership database were invited to participate. A total of 209 members out of the total of 211 fulfilled these criteria and were included in the study population. The response rate was 51% (106/209). Of respondents, 42% felt that ED was a significant problem at their institutions, with 45% giving medication before or during anesthesia to prevent the development of ED. Propofol was the most common medication given to prevent ED (68%) and to treat ED (42%). Total intravenous anesthesia (TIVA) was considered by 38% of respondents as a technique used to prevent ED. Medications used for treatment included propofol (42%), midazolam (31%), fentanyl (10%), morphine (7%), and dexmedetomidine (5%), with 87% of respondents rating effectiveness of treatment as 'usually works quickly with one dose'. We present information on current practice patterns with respect to prophylaxis and treatment of ED among a specialized group of pediatric

    Magnetization transfer (MT) imaging is a special MR technique used for selective suppression of the MR signal of protons bound on macromolecules. The most important applications in neuroradiology are (1) detection of subtle changes in otherwise normal-appearing cerebral white matter, for instance in multiple sclerosis (MS), Wallerian degeneration, and hydrocephalus, (2) differentiation of white matter lesions with high signal on T{sub 2}-weighted MR-images, like MS plaques, brain infarctions, and brain edema, (3) follow-up of cerebral white matter diseases using volumetric MT techniques, and (4) improvement in delineating of contrast enhancing brain lesions, such as cerebral metastases. We describe the physical rationale of the MT technique and present the most important current and possible future applications of MT imaging to answer clinical and scientific questions in neuroradiology. (orig.) [German] Die Magnetisierungstransfer-(MT)-Technik ist ein spezielles MRT-Verfahren, mit dem selektiv das MR-Signal der an Makromolekuele gebundenen Protonen unterdrueckt werden kann. Die wichtigsten Anwendungen dieser Technik in der Neuroradiologie sind der Nachweis von subtilen Veraenderungen in ansonsten normal erscheinender weisser Hirnsubstanz, wie z.B. bei Multipler Sklerose (MS), Waller'scher Degeneration und Hydrozephalus, die Differenzierung von Laesionen der weissen Substanz, die durchgaengig hohes Signal auf T{sub 2}-gewichteten MRT-Aufnahmen zeigen, wie z.B. MS-Plaques, Hirninfarkte oder Hirnoedem, die Verlaufskontrolle von Erkrankungen der weissen Substanz mit der volumetrischen MT-Technik, und die Verbesserung der Abgrenzbarkeit kontrasmittelaufnehmender Hirnlaesionen wie Hirnmetastasen. Wir beschreiben die MR-physikalischen Grundlagen der MT-Technik und stellen die wesentlichen aktuellen und moeglichen zukuenftigen Anwendungen zur Beantwortung klinischer und wissenschaftlicher Fragestellungen in der Neuroradiologie vor.

    As in adult anesthesia, morbidity and mortality could be significantly reduced in pediatric anesthesia in recent decades. This fact cannot conceal the fact that the incidence of anesthetic complications in children is still much more common than in adults and sometimes with a severe outcome. Newborns and infants in particular but also children with emergency interventions and severe comorbidities are at increased risk of potential complications. Typical complications in pediatric anesthesia are respiratory problems, medication errors, difficulties with the intravenous puncture and pulmonal aspiration. In the postoperative setting, nausea and vomiting, pain, and emergence delirium can be mentioned as typical complications. In addition to the systematic prevention of complications in pediatric anesthesia, it is important to quickly recognize disturbances of homeostasis and treat them promptly and appropriately. In addition to the expertise of the performing anesthesia team, the institutional structure in particular can improve quality and safety in pediatric anesthesia.

    The incidence of pediatric nephrolithiasis is on the rise. The composition of kidney stones in children is different than in adults, as most stones in children have a composition of calcium oxalate and calcium phosphate mixed with a small amount of uric acid. The symptoms of pediatric nephrolithiasis are nonspecific. Computed tomography (CT) is the gold standard for diagnosis; however, because of radiation exposure associated with a CT scan, ultrasonography is also an accepted modality for the diagnosis. Extensive metabolic evaluation is important to rule out an underlying metabolic disorder. Urinary decompression, medical expulsion therapy, and surgical interventions such as ureteroscopy and extracorporeal shockwave lithotripsy are some of the options available for treating pediatric nephrolithiasis.

  7. Pediatric vascular access

    International Nuclear Information System (INIS)

    Donaldson, James S.

    2006-01-01

    Pediatric interventional radiologists are ideally suited to provide vascular access services to children because of inherent safety advantages and higher success from using image-guided techniques. The performance of vascular access procedures has become routine at many adult interventional radiology practices, but this service is not as widely developed at pediatric institutions. Although interventional radiologists at some children's hospitals offer full-service vascular access, there is little or none at others. Developing and maintaining a pediatric vascular access service is a challenge. Interventionalists skilled in performing such procedures are limited at pediatric institutions, and institutional support from clerical staff, nursing staff, and technologists might not be sufficiently available to fulfill the needs of such a service. There must also be a strong commitment by all members of the team to support such a demanding service. There is a slippery slope of expected services that becomes steeper and steeper as the vascular access service grows. This review is intended primarily as general education for pediatric radiologists learning vascular access techniques. Additionally, the pediatric or adult interventional radiologist seeking to expand services might find helpful tips. The article also provides education for the diagnostic radiologist who routinely interprets radiographs containing vascular access devices. (orig.)

    Radioisotope brain imaging has focused mainly on regional cerebral blood flow (rCBF). However the use of ligand which go to specific receptor sites is being introduced in pediatrics, mainly psychiatry. rCBF is potentially available in many institutions, especially with the availability of multi-headed gamma cameras. The use of this technique in pediatrics requires special attention to detail in the manner of data acquisition and handling the child. The interpretation of the rCBF study in a child requires knowledge of normal brain maturation. The major clinical use in pediatrics is epilepsy because of the advances in surgery and the frequency of complex partial seizures. Other indications in pediatric neurology include brain death, acute neurological loss including stroke, language disorders, cerebral palsy, hypertension due to renovascular disease, traumatic brain injury and migraine. There are pediatric physiological conditions in which rCBF has been undertaken, these include anorexia nervosa, autism, Gilles de la Tourette syndrome (GTS) and attention deficit disorder-hyperactivity (ADHD). Research using different ligands to specific receptor sites will also be reviewed in pediatrics

    This paper assesses the spectrum of neuroradiologic findings in children with symptomatic HIV infection. Cranial CT and MR imaging studies in 31 children with symptomatic HIV infection were retrospectively reviewed. Twenty-eight children were evaluated with CT scanning and 12 with MR imaging. Studies were performed in 17 cases because of abnormal neurologic symptoms and 14 children underwent non-contrast-enhanced CT prior to admission to NIAID research drug trials. The spectrum of findings consisted of abnormalities in the white matter in 14, cerebral atrophic-like changes in 13, abnormal intracranial calcifications in five, cerebral infarction in two, and multifocal cerebral abscesses secondary to disseminated histoplasmosis in one patient

    Fehr, James J; Honkanen, Anita; Murray, David J

    2012-10-01

    Simulation-based training, research and quality initiatives are expanding in pediatric anesthesiology just as in other medical specialties. Various modalities are available, from task trainers to standardized patients, and from computer-based simulations to mannequins. Computer-controlled mannequins can simulate pediatric vital signs with reasonable reliability; however the fidelity of skin temperature and color change, airway reflexes and breath and heart sounds remains rudimentary. Current pediatric mannequins are utilized in simulation centers, throughout hospitals in-situ, at national meetings for continuing medical education and in research into individual and team performance. Ongoing efforts by pediatric anesthesiologists dedicated to using simulation to improve patient care and educational delivery will result in further dissemination of this technology. Health care professionals who provide complex, subspecialty care to children require a curriculum supported by an active learning environment where skills directly relevant to pediatric care can be developed. The approach is not only the most effective method to educate adult learners, but meets calls for education reform and offers the potential to guide efforts toward evaluating competence. Simulation addresses patient safety imperatives by providing a method for trainees to develop skills and experience in various management strategies, without risk to the health and life of a child. A curriculum that provides pediatric anesthesiologists with the range of skills required in clinical practice settings must include a relatively broad range of task-training devises and electromechanical mannequins. Challenges remain in defining the best integration of this modality into training and clinical practice to meet the needs of pediatric patients. © 2012 Blackwell Publishing Ltd.

    Full Text Available Nanette B SilverbergPediatric and Adolescent Dermatology, St. Luke’s-Roosevelt Hospital Center, New York, NY, USAAbstract: Pediatric psoriasis consists broadly of 3 age groups of psoriatic patients: infantile psoriasis, a self-limited disease of infancy, psoriasis with early onset, and pediatric psoriasis with psoriatic arthritis. About one-quarter of psoriasis cases begin before the age of 18 years. A variety of clinical psoriasis types are seen in childhood, including plaque-type, guttate, erythrodermic, napkin, and nail-based disease. Like all forms of auto-immunity, susceptibility is likely genetic, but environmental triggers are required to initiate disease activity. The most common trigger of childhood is an upper respiratory tract infection. Once disease has occurred, treatment is determined based on severity and presence of joint involvement. Topical therapies, including corticosteroids and calcipotriene, are the therapies of choice in the initial care of pediatric patients. Ultraviolet light, acitretin and cyclosporine can clear skin symptoms, while methotrexate and etanercept can clear both cutaneous and joint disease. Concern for psychological development is required when choosing psoriatic therapies. This article reviews current concepts in pediatric psoriasis and a rational approach to therapeutics. Keywords: psoriasis, autoimmunity, Streptococcus, etanercept, calcipotriene, topical corticosteroids

    High-quality PET imaging of pediatric patients is challenging and requires attention to issues commonly encountered in the practice of pediatric nuclear medicine, but uncommon to the imaging of adult patients. These include intravenous access, fasting, sedation, consent, and clearance of activity from the urinary tract. This paper discusses some technical differences involved in pediatric PET to enhance the quality of scans and assure the safety and comfort of pediatric patients. (orig.)

    This symposium presented the latest techniques and approaches to the proper medical application of radionuclides in pediatrics. An expert faculty, comprised of specialists in the field of pediatric nuclear medicine, discussed the major indications as well as the advantages and potential hazards of nuclear medicine procedures compared to other diagnostic modalities. In recent years, newer radiopharmaceuticals labeled with technetium-99m and other short-lived radionuclides with relatively favorable radiation characteristics have permitted a variety of diagnostic studies that are very useful clinically and carry a substantially lower radiation burden then many comparable X-ray studies. This new battery of nuclear medicine procedures is now widely available for diagnosis and management of pediatric patients. Many recent research studies in children have yielded data concerning the effacacy of these procedures, and current recommendations will be presented by those involved in conducting such studies.

    Sleeping beauties (SBs) in science have been known for few decades; however, it seems that only recently have they become popular. An SB is a publication that "sleeps" for a long time and then almost suddenly awakes and becomes highly cited. SBs present interesting findings in science. Pediatrics research literature has not yet been analyzed for their presence, and 5 pediatrics SBs were discovered in this research. Their prevalence was approximately 0.011%. Some environments or periods are more "SB fertile" than others: 3 of 5 SBs were published in the journal Pediatrics, 4 originated from the United States, and 4 were published in the period from 1992 to 1993. No institutions or authors published more than 1 SB.

    1987-01-01

    Nuclear cardiology methods have had less impact upon pediatric cardiology than upon adult cardiology. Most pediatric heart disease results from congenital malformations of the heart and great vessels, which is usually discovered in infancy, and is most often treated definitively in infancy or early childhood. Unfortunately, nuclear medicine techniques are limited in their spatial resolution - structures that overlie each other are separated with difficulty. As a result, nuclear cardiology is usually of limited value in the anatomic characterization of the congenital heart abnormalities. Nevertheless, it has been useful in the detection and quantification of the pathophysiologic consequences of many congenital cardiac malformations. The authors review application of nuclear medicine in pediatric cardiology, and attempt to assess each in terms of its clinical utility

    2011-08-01

    Risk in pediatric anesthesia can be conveniently classified as minor or major. Major morbidity includes cardiac arrest, brain damage and death. Minor morbidity can be assessed by clinical audits with small patient samples. Major morbidity is rare. It is best assessed by very large clinical studies and by review of closed malpractice claims. Both minor and major morbidity occur most commonly in infants and children under three, especially those with severe co-morbidities. Knowledge of risk profiles in pediatric anesthesia is a starting point for the reduction of risk. © 2010 Blackwell Publishing Ltd.

    Contact dermatitis is an umbrella term that describes the skin's reaction to contacted noxious or allergenic substances. The two main categories of contact dermatitis are irritant type and allergic type. This review discusses the signs, symptoms, causes, and complications of contact dermatitis. It addresses the testing, treatment, and prevention of contact dermatitis. Proper management of contact dermatitis includes avoidance measures for susceptible children. Implementation of a nickel directive (regulating the use of nickel in jewelry and other products that come into contact with the skin) could further reduce exposure to the most common allergens in the pediatric population.

    From 2006 to 2013, 12 patients with severe epistaxis refractory to prior conservative and surgical therapy were treated by superselective embolization of nasal arteries. Supersoft platinum microcoils with smallest diameters were used as the sole embolic agent in all cases. Coils were applied far distally in a stretched position for obtaining ideal target vessel superselectivity. The objective of this study is to evaluate efficacy and complications of superselective coil embolization for treatment of severe intractable epistaxis and to discuss results from an otorhinolaryngologic and an interventional neuroradiologic point of view. Retrospectively, all epistaxis inpatients between 2006 and 2013 were identified and subdivided by form of treatment: conservative, surgical and interventional therapy. Medical records of interventionally treated patients were reviewed for demographics, medical history, risk factors, clinical data, complications and short-term success, and patients were followed up for long-term success. Mean follow-up was 37 months. In 12 patients, 14 embolizations were carried out, with short-term success in 9 patients (75%), while early post-interventional rebleeding occurred in 3 patients (25%). Of 9 patients with short-term success, 1 died during stay, 1 was lost to follow-up and 1 had minor re-bleeding after 30 months. Six patients had short-term and long-term success. Before the first embolization, 3 ± 1 conservative and/or surgical procedures had been undertaken. Length of stay was 12.8 ± 3.6 days. 8 patients (67%) received red cell concentrates. Most frequent complications were mucosal damage and nasal pain, but these were related to repeated packing and surgery. Typical embolic complications as neurological or visual impairment or soft tissue necrosis were not observed in any patient. From the otorhinolaryngologic point of view, surgery is the treatment of choice in severe refractory epistaxis, but in case of repeated failure, superselective

    Qualitative radiologic MR imaging review affords limited differentiation among types of pediatric posterior fossa brain tumors and cannot detect histologic or molecular subtypes, which could help to stratify treatment. This study aimed to improve current posterior fossa discrimination of histologic tumor type by using support vector machine classifiers on quantitative MR imaging features. This retrospective study included preoperative MRI in 40 children with posterior fossa tumors (17 medulloblastomas, 16 pilocytic astrocytomas, and 7 ependymomas). Shape, histogram, and textural features were computed from contrast-enhanced T2WI and T1WI and diffusivity (ADC) maps. Combinations of features were used to train tumor-type-specific classifiers for medulloblastoma, pilocytic astrocytoma, and ependymoma types in separation and as a joint posterior fossa classifier. A tumor-subtype classifier was also produced for classic medulloblastoma. The performance of different classifiers was assessed and compared by using randomly selected subsets of training and test data. ADC histogram features (25th and 75th percentiles and skewness) yielded the best classification of tumor type (on average >95.8% of medulloblastomas, >96.9% of pilocytic astrocytomas, and >94.3% of ependymomas by using 8 training samples). The resulting joint posterior fossa classifier correctly assigned >91.4% of the posterior fossa tumors. For subtype classification, 89.4% of classic medulloblastomas were correctly classified on the basis of ADC texture features extracted from the Gray-Level Co-Occurence Matrix. Support vector machine-based classifiers using ADC histogram features yielded very good discrimination among pediatric posterior fossa tumor types, and ADC textural features show promise for further subtype discrimination. These findings suggest an added diagnostic value of quantitative feature analysis of diffusion MR imaging in pediatric neuro-oncology. © 2014 by American Journal of Neuroradiology.

    Radiological interventions possess wide utilization in the diagnosis and treatment for pediatric patients. Pediatric interventional radiology is an important branch of interventional radiology and also an important branch of pediatric radiology. Pediatric interventional radiology has grown substantially over the last 30 years, radiologists closely cooperation with surgeons and other physicians providing a new horizon in the management of pediatric diseases in western countries. It includes pediatric cardiac interventional radiology, pediatric neuro-interventional radiology, pediatric vascular interventional radiology, pediatric nonvascular interventional radiology, pediatric tumor interventional radiology and others. In the United States, every children hospital which owns two hundred beds has to have special trained interventional radiologists in radiologic department installing with advanced digital subtraction angiographic equipment. Interventional therapeutic procedures and diagnostic angiography have been proceeding more and more for the congenital and acquired diseases of children. The promising results give use uprising and interventional therapy as an alternative or a replacement or supplement to surgical operation. Pediatric interventional radiology is rather underdeveloped in China with a few special pediatric interventional radiologist, lack of digital subtraction angiography equipment. Pediatric radiologists have no enough field for interventional procedures such as pediatric neuro-interventional radiology and pediatric vascular interventional radiology. In the contrary adult interventional radiologists do have better interventional jobs in China and Pediatric cardiologists also share the same trend. They perform angiocardiography for congenital heart diseases and treat congenital heart disease with interventional procedures including balloon dilation of valves and vessels, coil embolization of collaterals, patent ducts and other arterial fistulae

    Full Text Available Pediatric obesity is a major health problem and has reached epidemiological proportions today. The present paper reviews major psychological issues in pediatric obesity from a developmental perspective. Research and literature has shown that a number of developmental, family, maternal and child factors are responsible in the genesis of pediatric obesity. Family food habits, early developmental lifestyle of the child, parenting, early family relationships and harmony all contribute towards the growth and development of a child. The present review focuses on the role of developmental psychological factors in the pathogenesis of pediatric obesity and highlights the developmental factors that must be kept in mind when evaluating a case of pediatric obesity.

    Although pediatric patients are sometimes included in studies about visual problems in patients with acquired brain injury (ABI), few studies deal solely with children. Unlike studies dealing with adult patients, in which mechanisms of brain injury are divided into cerebral vascular accident (CVA) and traumatic brain injury (TBI), studies on pediatric patients deal almost exclusively with traumatic brain injury, specifically caused by accidents. Here we report on the vision problems of 4 pediatric patients, ages 3 to 18 years, who were examined in the ophthalmology/optometry clinic at a children's hospital. All patients had an internally caused brain injury and after the initial insult manifested problems in at least one of the following areas: acuity, binocularity, motility (tracking or saccades), accommodation, visual fields, and visual perceptual skills. Pediatric patients can suffer from a variety of oculo-visual problems after the onset of head injury. These patients may or may not be symptomatic and can benefit from optometric intervention.

    We examined the frequency, neuroradiological features, and risk factors of Alzheimer-type dementia (DAT) in 123 Japanese adult patients with Down`s syndrome. Among these patients 16 were diagnosed as having DAT. The prevalence of DAT was 0% in the 18- to 39-year-old group, 16% in those aged 40 to 49 years old, and 38% in those over 50 years old. On CT examination, the earliest finding of DAT was atrophy of the temporal lobe. Patients at an advanced stage revealed extensive atrophy of the cerebral hemispheres, frequently associated with calcification of the basal ganglia. {sup 123}I-IMP-SPECT studies showed abnormally decreased isotope uptake in the posterior parietal regions in Down`s syndrome patients with DAT, and a similar finding was also seen in Down`s syndrome patients who showed severe mental retardation. The frequency of the apolipoprotein E (ApoE) E4 in Down`s syndrome patients with DAT was 18.8%, which was higher than that of non-demented Down`s syndrome patients (4.5%) and Japanese non-demented controls (6.7%). In particular, the frequency of the ApoE E4 in patients who developed DAT before 50 years of age was significantly high (28.6%). It is very likely that the ApoE E4 is a risk factor for DAT even in Down`s syndrome patients with a genetic predisposition to Alzheimer`s disease. (author)

    2015-10-01

    Originally aimed at improving standard radiography by providing higher absorption efficiency and a wider dynamic range, flat-panel detector technology has meanwhile got widely accepted in the neuroradiological community. Especially flat-panel detector computed tomography (FD-CT) using rotational C-arm mounted flat-panel detector technology is capable of volumetric imaging with a high spatial resolution. By providing CT-like images of the brain within the angio suite, FD-CT is able to rapidly visualize hemorrhage and may thus improve complication management without the need of patient transfer. As "Angiographic CT" FD-CT may be helpful during many diagnostic and neurointerventional procedures and for noninvasive monitoring and follow-up. In addition, spinal interventions and high-resolution imaging of the temporal bone might also benefit from FD-CT. Finally, using novel dynamic perfusion and angiographic protocols, FD-CT may provide functional information on brain perfusion and vasculature with the potential to replace standard imaging in selected acute stroke patients.

    In recent years, NMR imaging has become a most important tool for the diagnosis of central nervous disorders in children. Using this non-invasive method, which also obviates the need for ionizing rays, it was possible to gain entirely new insights into certain types of neuropaediatric diseases. The particular role of NMR imaging in the assessment of such changes hence was the topic discussed at the 13th Symposium of Neuroradiological Contrast Media. The special journal offers a choice of the papers read on that occasion, among them contributions on methods of anaesthesia used in NMR imaging, on gadolinium DTPA, the physiological development of the infantile brain, congenital malformations and disorders, neurodegenerative and inflammatory diseases, malformations developing during childhood as well as on the limitations that NMR imaging was found to have in the fields of neuropaediatrics and neuropathology.

    The Philips Computed Radiography system performs well with pediatric portable chest radiographs, handling the throughout of a busy intensive care service 24 hours a day. Images are excellent and routinely provide a conventional (unenhanced) image and an edge-enhanced image. Radiation dose is decreased by the lowered frequency of repeat examinations and the ability of the plates to respond to a much lower dose and still provide an adequate image. The high quality and uniform density of serial PCR portable radiographs greatly enhances diagnostic content of the films. Decreased resolution has not been a problem clinically. Image manipulation and electronic transfer to remote viewing stations appear to be helpful and are currently being evaluated further. The PCR system provides a marked improvement in pediatric portable chest radiology.

    Hippocrates of Kos is well known in medicine, but his contributions to pediatric dermatology have not previously been examined. A systematic study of Corpus Hippocraticum was undertaken to document references of clinical and historical importance of pediatric dermatology. In Corpus Hippocraticum, a variety of skin diseases are described, along with proposed treatments. Hippocrates rejected the theory of the punishment of the Greek gods and supported the concept that dermatologic diseases resulted from a loss of balance in the body humors. Many of the terms that Hippocrates and his pupils used are still being used today. Moreover, he probably provided one of the first descriptions of skin findings in smallpox, Henoch-Schönlein purpura (also known as anaphylactoid purpura, purpura rheumatica, allergic purpura), and meningococcal septicemia. © 2015 Wiley Periodicals, Inc.

  6. Telemedicine: Pediatric Applications

    Science.gov (United States)

    Burke, Bryan L.; Hall, R. W.

    2017-01-01

    Telemedicine is a technological tool that is improving the health of children around the world. This report chronicles the use of telemedicine by pediatricians and pediatric medical and surgical specialists to deliver inpatient and outpatient care, educate physicians and patients, and conduct medical research. It also describes the importance of telemedicine in responding to emergencies and disasters and providing access to pediatric care to remote and underserved populations. Barriers to telemedicine expansion are explained, such as legal issues, inadequate payment for services, technology costs and sustainability, and the lack of technology infrastructure on a national scale. Although certain challenges have constrained more widespread implementation, telemedicine’s current use bears testimony to its effectiveness and potential. Telemedicine’s widespread adoption will be influenced by the implementation of key provisions of the Patient Protection and Affordable Care Act, technological advances, and growing patient demand for virtual visits.

    Among all causes of death in children from solid tumors, pediatric brain tumors are the most common. This article includes an overview of a subset of infratentorial and supratentorial tumors with a focus on tumor imaging features and molecular advances and treatments of these tumors. Key to understanding the imaging features of brain tumors is a firm grasp of other disease processes that can mimic tumor on imaging. We also review imaging features of a common subset of tumor mimics. (orig.)

    Full Text Available Acitretin, a synthetic retinoid and the active metabolite of etretinate has been increasingly used over the past two decades. It has proved effective in the treatment of many conditions associated with hyperkeratosis and dyskeratosis. A Google scholar search for the use of acitretin in pediatric dermatoses was done using the words “pediatric dermatoses,” “acitretin,” “etretinate,” “systemic retinoids,” “psoriasis,” “pityriasis rubra pilaris,” “ichthyoses,” “disorders of keratinization,” “Darier's disease,” “palmoplantar keratoderma,” “verrucae,” “lichen planus,” “lupus erythematosus,” and “lichen sclerosus.” All the articles were retrieved and classified into review articles, studies, double-blinded trials, and case reports. The final data were then analyzed and presented in a narrative fashion. It has been found that acitretin is useful in a number of pediatric dermatoses. It is preferred over other drugs in pustular psoriasis. Good results can be obtained in various disorders of keratinization, and it may even prove life-saving in conditions like harlequin ichthyosis. However, long-term maintenance therapy is required and exacerbations are known on discontinuing the drug. It can also be used as alternative therapy for many other pediatric dermatoses where the primary treatment has failed. Acitretin should be used even in children for the proper indications. However, proper clinical and laboratory surveillance has to be maintained in patients on long-term acitretin.

    2018-01-01

    Acute kidney injury (AKI) in children is a serious condition with an important impact on morbidity and mortality. Onset can be insidious and it is frequently unrecognized in the early phase when the therapeutic opportunities are theoretically more effective. The present review focuses on the most recent epidemiology studies and the progress in pediatric AKI (pAKI) research. Standardization of definition (presented in the Kidney Disease: Improving Global Outcomes) and novel biomarkers have been developed to help clinicians recognize kidney injury in a timely manner, both in adult and pediatric populations. Strengths and weaknesses of these diagnostic tools are discussed and the clinical scoring system (Renal Angina Index), which aims to provide a rational context for biomarker utilization, is also presented. Even if effective treatments are not currently available for established AKI, specific preventive approaches and some promising pharmacological treatments will be detailed. Renal replacement therapy is currently considered the most effective way to manage fluid balance when severe AKI occurs. Key Messages: Great efforts in pAKI research have today led to new strategies for early AKI detection and prevention strategies. Further studies have to be conducted in the next future in order to definitely improve the outcomes of pediatric patients experiencing this deadly syndrome. © 2018 S. Karger AG, Basel.

    2017-04-01

    The implications of childhood obesity on pediatric trauma outcomes are not clearly established. Anthropomorphic data were recently added to the National Trauma Data Bank (NTDB) Research Datasets, enabling a large, multicenter evaluation of the effect of obesity on pediatric trauma patients. Children ages 2 to 19years who required hospitalization for traumatic injury were identified in the 2013-2014 NTDB Research Datasets. Age and gender-specific body mass indices (BMI) were calculated. Outcomes included injury patterns, operative procedures, complications, and hospital utilization parameters. Data from 149,817 pediatric patients were analyzed; higher BMI percentiles were associated with significantly more extremity injuries, and fewer injuries to the head, abdomen, thorax and spine (p values Obese children also had significantly longer lengths of stay and more frequent ventilator requirement. Among children admitted after trauma, increased BMI percentile is associated with increased risk of death and potentially preventable complications. These findings suggest that obese children may require different management than nonobese counterparts to prevent complications. Level III; prognosis study. Copyright © 2017 Elsevier Inc.

  18. Pediatric Melanoma and Drug Development

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available Importance—Pediatric melanoma occurs, albeit rarely. Should patients be treated by today’s medical standards, or be subjected to medically unnecessary clinical studies? Observations—We identified international, industry-sponsored pediatric melanoma studies triggered by regulatory demands in www.clinicaltrials.gov and further pediatric melanoma studies demanded by European Union pediatric investigation plans. We retrieved related regulatory documents from the internet. We analyzed these studies for rationale and medical beneficence on the basis of physiology, pediatric clinical pharmacology and rationale. Regulatory authorities define children by chronological age, not physiologically. Newborns’ organs are immature but they develop and mature rapidly. Separate proof of efficacy in underage patients is justified formally/regulatorily but lacks medical sense. Children—especially post-puberty—and adults vis-a-vis medications are physiologically very similar. Two adolescent melanoma studies were terminated in 2016 because of waning recruitment, while five studies in pediatric melanoma and other solid tumors, triggered by European Union pediatric investigation plans, continue recruiting worldwide. Conclusions and Relevance—Regulatory-demanded pediatric melanoma studies are medically superfluous. Melanoma patients of all ages should be treated with effective combination treatment. Babies need special attention. Children need dose-finding and pharmacokinetic studies but adolescents metabolize and respond to drugs similarly to adults. Institutional Review Boards/ethics committees should suspend ongoing questionable pediatric melanoma studies and reject newly submitted questionable studies.

    There is a lack of dosing guidelines for use in obese children. Moreover, the impact of obesity on drug safety and clinical outcomes is poorly defined. The paucity of information needed for the safe and effective use of drugs in obese patients remains a problem, even after drug approval. To assess the current incorporation of obesity as a covariate in pediatric drug development, the pediatric medical and clinical pharmacology reviews under the Food and Drug Administration (FDA) Amendments Act of 2007 and the FDA Safety and Innovation Act (FDASIA) of 2012 were reviewed for obesity studies. FDA labels were also reviewed for statements addressing obesity in pediatric patients. Forty-five drugs studied in pediatric patients under the FDA Amendments Act were found to have statements and key words in the medical and clinical pharmacology reviews and labels related to obesity. Forty-four products were identified similarly with pediatric studies under FDASIA. Of the 89 product labels identified, none provided dosing information related to obesity. The effect of body mass index on drug pharmacokinetics was mentioned in only 4 labels. We conclude that there is little information presently available to provide guidance related to dosing in obese pediatric patients. Moving forward, regulators, clinicians, and the pharmaceutical industry should consider situations in drug development in which the inclusion of obese patients in pediatric trials is necessary to facilitate the safe and effective use of new drug products in the obese pediatric population. © 2018, The American College of Clinical Pharmacology.

    Pediatric patients often undergo anesthesia for ambulatory procedures. This article discusses several common preoperative dilemmas, including whether to postpone anesthesia when a child has an upper respiratory infection, whether to test young women for pregnancy, which children require overnight admission for apnea monitoring, and the effectiveness of nonpharmacological techniques for reducing anxiety. Medication issues covered include the risks of anesthetic agents in children with undiagnosed weakness, the use of remifentanil for tracheal intubation, and perioperative dosing of rectal acetaminophen. The relative merits of caudal and dorsal penile nerve block for pain after circumcision are also discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Pediatric urology is a pediatric speciality dedicated to the diagnosis and treatment of congenital and acquired genitourinary tract diseases. It is a speciality that is rapidly changing, thanks to the technological development that has been emerging in recent years. There have been important diagnostic and therapeutic news.Congenital anomalies of the kidneys and urinary tract (CAKUT include various entities of structural malformations that result from defects in their morphogenesis. Clinical research and genetic studies on the origins of CAKUT are quickly evolving, with significant growth of high-quality research.Management goals of CAKUT include prevention of febrile urinary tract infections (UTIs in newborns and toddles and renal injury, while minimizing the morbidity of treatment and follow-up. Treatment options include observation with or without continuous antibiotic prophylaxis (CAP and surgical correction. Now, randomized controlled studies show that children with normal urinary tracts or low-grade vesicoureteral reflux (VUR do not benefit from prophylaxis.All children with known mechanical or functional obstructions of the urinary tract are considered to have UTI. Functional obstruction often results from lower urinary tract dysfunction (LUTD of either neurogenic or non-neurogenic origin and dilating VUR.The role of bladder and bowel dysfunction (BBD in children with UTI and the long-term risk of renal scarring have shed new light on treatment strategies. Often it is BBD, rather than reflux, that causes UTI in children older than 2 years.Pediatric urology has evolved in recent years, with a greater focus on bladder and renal function, minimally invasive treatment, evidence-based interventions, and guideline adherence. Other topics in pediatric urology include urinary incontinence in children with special needs and the use of robot-assisted laparoscopic surgery (RALS in children, with advantages over conventional laparoscopic surgery

    Indirect inguinal hernias are the most commonly incarcerated hernias in children, with a higher incidence in low birth weight and premature infants. Contralateral groin exploration to evaluate for a patent processus vaginalis or subclinical hernia is controversial, given that most never progress to clinical hernias. Most indirect inguinal hernias can be reduced nonoperatively. It is recommended to repair them in a timely fashion, even in premature infants. Laparoscopic repair of incarcerated inguinal hernia repair is considered a safe and effective alternative to conventional open herniorrhaphy. Other incarcerated pediatric hernias are extremely rare and may be managed effectively with laparoscopy. Copyright © 2016 Elsevier Inc. All rights reserved.

  13. Pediatric contact dermatitis

    Directory of Open Access Journals (Sweden)

    Sharma Vinod

    2010-01-01

    Full Text Available Allergic contact dermatitis (ACD in children, until recently, was considered rare. ACD was considered as a disorder of the adult population and children were thought to be spared due to a lack of exposure to potential allergens and an immature immune system. Prevalence of ACD to even the most common allergens in children, like poison ivy and parthenium, is relatively rare as compared to adults. However, there is now growing evidence of contact sensitization of the pediatric population, and it begins right from early childhood, including 1-week-old neonates. Vaccinations, piercing, topical medicaments and cosmetics in younger patients are potential exposures for sensitization. Nickel is the most common sensitizer in almost all studies pertaining to pediatric contact dermatitis. Other common allergens reported are cobalt, fragrance mix, rubber, lanolin, thiomersol, neomycin, gold, mercapto mix, balsum of Peru and colophony. Different factors like age, sex, atopy, social and cultural practices, habit of parents and caregivers and geographic changes affect the patterns of ACD and their variable clinical presentation. Patch testing should be considered not only in children with lesions of a morphology suggestive of ACD, but in any child with dermatitis that is difficult to control.

  14. Pharmacology of pediatric resuscitation.

    Ushay, H M; Notterman, D A

    1997-02-01

    The resuscitation of children from cardiac arrest and shock remains a challenging goal. The pharmacologic principles underlying current recommendations for intervention in pediatric cardiac arrest have been reviewed. Current research efforts, points of controversy, and accepted practices that may not be most efficacious have been described. Epinephrine remains the most effective resuscitation adjunct. High-dose epinephrine is tolerated better in children than in adults, but its efficacy has not received full analysis. The preponderance of data continues to point toward the ineffectiveness and possible deleterious effects of overzealous sodium bicarbonate use. Calcium chloride is useful in the treatment of ionized hypocalcemia but may harm cells that have experienced asphyxial damage. Atropine is an effective agent for alleviating bradycardia induced by increased vagal tone, but because most bradycardia in children is caused by hypoxia, improved oxygenation is the intervention of choice. Adenosine is an effective and generally well-tolerated agent for the treatment of supraventricular tachycardia. Lidocaine is the drug of choice for ventricular dysrhythmias, and bretylium, still relatively unexplored, is in reserve. Many pediatricians use dopamine for shock in the postresuscitative period, but epinephrine is superior. Most animal research on cardiac arrest is based on models with ventricular fibrillation that probably are not reflective of cardiac arrest situations most often seen in pediatrics.

  15. Pediatric spinal infections

    Directory of Open Access Journals (Sweden)

    Raj Kumar

    2014-01-01

    Full Text Available The infections of the spinal axis in children are rare when compared with adults. They encompass a large spectrum of diseases ranging from relatively benign diskitis to spinal osteomyleitis and to the rapidly progressive, rare, and potentially devastating spinal epidural, subdural, and intramedullary spinal cord infections. We present a comprehensive review of the literature pertaining to these uncommon entities, in light of our experience from northern India. The most prevalent pediatric spinal infection in Indian scenario is tuberculosis, where an extradural involvement is more common than intradural. The craniovertebral junction is not an uncommon site of involvement in children of our milieu. The majority of pyogenic infections of pediatric spine are associated with congenital neuro-ectodermal defects such as congenital dermal sinus. The clinico-radiological findings of various spinal infections commonly overlap. Hence the endemicity of certain pathogens should be given due consideration, while considering the differential diagnosis. However, early suspicion, rapid diagnosis, and prompt treatment are the key factors in avoiding neurological morbidity and deformity in a growing child.

    Coca Robinot, D; Liébana de Rojas, C; Aguirre Pascual, E

    2016-05-01

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition. Copyright © 2016 SERAM.

    1997-12-01

    This article summarizes the major PET studies which have been performed in pediatric patients to elucidate and characterize diseases and normal development. Issues special for the application of the technique in children, such as dosimetry, patient preparation, and image acquisition are discussed. Studies of central nervous system (CNS) development and pathology, including epilepsy, intraventricular hemorrhage, neonatal asphyxia, tumors, and effects on the CNS from treatment of other tumors are reviewed. These have contributed information fundamental to their understanding of CNS development and pathology. PET investigations into the pathophysiology of congenital heart disease have begun and hold great promise to aid their understanding of these conditions. The second major area in which PET has been applied is the study of non CNS neoplasms. Neuroblastoma has been investigated with tracers which explore basic biochemical features which characterize this tumor, as well as with tracers which explore biochemical events relatively specific for this malignancy. Other common and uncommon tumors of childhood are discussed. The PET technique has been shown useful for answering questions of clinical relevance for the management of these uncommon neoplasms. PET is likely to continue to aid their understanding of many pediatric diseases and may gain more widespread clinical acceptance as the technology continues to disseminate rapidly.

    2017-01-01

    Full Text Available Vitamin D, a secosteroid, is essential for the development and maintenance of healthy bone in both the adult and pediatric populations. Low level of 25-hydroxy vitamin D (25-(OH-D is highly prevalent in children worldwide and has been linked to various adverse health outcomes including rickets, osteomalacia, osteomalacic myopathy, sarcopenia, and weakness, growth retardation, hypocalcemia, seizure and tetany, autism, cardiovascular diseases, diabetes mellitus, cancers (prostate, colon, breast, infectious diseases (viral, tuberculosis, and autoimmune diseases, such as multiple sclerosis and Hashimoto’s thyroiditis. Risk factors for hypovitaminosis D are people with darker skin pigmentation, use of sunscreen, insufficient ultraviolet B exposure, prematurity, living in northern latitudes, malnutrition, obesity, exclusive breastfeeding, low maternal vitamin D level, certain medications, drinking unfortified cow’s milk, liver failure, chronic renal insufficiency, cystic fibrosis, asthma, and sickle cell hemoglobinopathy. This review highlights and summarizes the molecular perspectives of vitamin D deficiency and its potential adverse health outcomes in pediatric age groups. The recommended treatment regimen is beyond the scope of this review.

  19. Pediatric DXA: clinical applications

    International Nuclear Information System (INIS)

    Binkovitz, Larry A.; Sparke, Paul; Henwood, Maria J.

    2007-01-01

    Normal bone mineral accrual requires adequate dietary intake of calcium, vitamin D and other nutrients; hepatic and renal activation of vitamin D; normal hormone levels (thyroid, parathyroid, reproductive and growth hormones); and neuromuscular functioning with sufficient stress upon the skeleton to induce bone deposition. The presence of genetic or acquired diseases and the therapies that are used to treat them can also impact bone health. Since the introduction of clinical DXA in pediatrics in the early 1990s, there has been considerable investigation into the causes of low bone mineral density (BMD) in children. Pediatricians have also become aware of the role adequate bone mass accrual in childhood has in preventing osteoporotic fractures in late adulthood. Additionally, the availability of medications to improve BMD has increased with the development of bisphosphonates. These factors have led to the increased utilization of DXA in pediatrics. This review summarizes much of the previous research regarding BMD in children and is meant to assist radiologists and clinicians with DXA utilization and interpretation. (orig.)

    While there are an abundance of pediatric neuropsychologists working with youth with epilepsy (YWE), other subspecialty psychologists have played minimal roles in clinical and research endeavors in pediatric epilepsy. Thus, the purpose of this commentary was to describe (a) the needs of YWE due to the intermittent nature of seizures and difficulties with disease management, (b) increased risk for psychosocial comorbidities, (c) limited access to care, and (d) provide recommendations for how pediatric psychologists can become involved in the clinical care and research activities for YWE.

    Full Text Available Lipofuscinose ceróide neuronal (LCN constitui um grupo de doenças neurodegenerativas caracterizadas pelo depósito anormal de uma substância autofluorescente de lipopigmentos, que lembra ceróide e lipofuscina, dentro dos lisossomos dos neurônios e outros tipos de células. Os principais subtipos fenotípicos, baseando-se na idade de início, curso clínico e morfologia ultraestrutural, são classificados em formas infantil, infantil tardia, juvenil e adulta. Seis genes associados a lipofuscinose ceróide foram identificados e aproximadamente 150 mutações também são descritas. Relatamos sete pacientes com LCN baseados na história clínica, achados neurorradiológicos e patológicos avaliados na Rede Sarah de Hospitais de Reabilitação - Fortaleza - Ceará - Brasil. Cinco casos foram confirmados com biópsia de pele, sendo dois casos irmãos de pacientes confirmados. O diagnóstico precoce de LCN, uma doença com herança autossômica recessiva, é mandatório para aconselhamento genético e prevenção de outros casos na família. Os achados de imagem podem contribuir no diagnóstico diferencial.The neuronal ceroid lipofuscinoses (NCL are a group of neurodegenerative disorders, characterized by abnormal storage of an autofluorescent substance of lipopigments, resembling ceroid and lipofuscin, within lysosomes of neurons and other types of cells.

    Full Text Available An 8-year-old male presents with two days of abdominal pain and emesis. Computed tomography was concerning for obstruction or reactive ileus with an apparent transition point in the right lower quadrant, possibly due to Crohn's. Magnetic resonance imaging was concerning for perforated appendicitis. As demonstrated by this case MRI can be as sensitive as CT in detecting pediatric appendicitis [2]. We recommend using MRI instead of CT to diagnose appendicitis to avoid ionizing radiation and increased cancer risk in the pediatric population.

    Clinical neuropsychology is a rapidly expanding field of study in the psychological sciences whose practitioners are expert in the assessment, treatment, and research of individuals with known or suspected central nervous system disease or disorder. Pediatric neuropsychology has emerged as a distinct subspecialty area with related education, training, and clinical expertise for a growing number of neuropsychologists. This paper details the numerous steps taken by two affiliated organizations, the American Board of Clinical Neuropsychology and its membership organization, the American Academy of Clinical Neuropsychology, in the interest of the larger pediatric neuropsychology community and in pediatric neuropsychology subspecialty development.

    The recreational use of trampolines has increased dramatically during the last 10 years. There has been a striking increase in the number of children presenting to fracture clinics with injuries associated with trampoline use. This increase in trampoline injuries has been reported in North America, but there has been a paucity of research in this area in Europe. We prospectively recorded details of patients presenting to our institution, Our Lady's Children's Hospital, Crumlin (Dublin, Ireland), during the busy summer months of June, July, and August 2005. Details recorded included type and mechanism of injury, the mode of referral, treatment, inpatient days, outpatient visits, specific details relating to trampoline safety, and an analysis of the cost of medical care. There were 101 patients treated for trampoline-related injuries in 3 months from June to August 2005. This represented 1.5% of the total attendances to the emergency department. The average age was 8.5 years (range, 1.4-17.4 years). There were 55 fractures, 38 soft tissue injuries, 5 head injuries, and 5 neck injuries, with an average Pediatric Trauma Score of 11.4. Fifty seven percent (58/101) of patients were on the trampoline with at least 1 other person. Twenty patients (19.8%) were admitted to hospital requiring 71 inpatient days. Twelve patients were treated in theatre. There were 163 fracture clinic visits, 212 x-rays, and 2 magnetic resonance imaging scans. Trampolines are a high-risk activity with the potential for significant orthopaedic injury. In Ireland, we have recently seen a dramatic increase in pediatric trampoline-related injuries mirroring the trend in the United States during the last 10 to 15 years. We found that more than 1 individual on a trampoline is a major risk factor for injury, where the lightest person is 14 times more likely to be injured than the heavier. The lighter person also has a greater chance of being injured with smaller numbers on the trampoline. We reiterate

    2017-03-01

    Headache represents the most common neurologic disorder in the general population including children and is increasingly being recognized as a major source of morbidity in youth related to missed school days and activities. In this article, we take a holistic approach to the child presenting with headache with a focus on the detailed headache history, physical and neurologic examinations, and diagnostic evaluation of these patients. Clinical presentations and classification schema of multiple primary and secondary headache types in children are discussed using the International Headache Criteria (IHCD-3) as a guide, and a summary provided of the various treatment modalities employed for pediatric headache including lifestyle modifications, behavioral techniques, and abortive and preventive medications.

    One of the principal benefits of contemporary multidetector row computed tomography (MDCT) has been the ability to obtain high-data sets for evaluation of the cardiovascular system. The benefits of the greater number of detector rows and submillimeter image thicknesses were quickly recognized and are especially advantageous in children. For example, since imaging is performed so quickly, issues with motion are minimized. This is a substantial benefit of CTA compared with MR imaging, the traditional noninvasive cross sectional modality for pediatric cardiovascular imaging. This, together with faster and more powerful computers, including improved transfer and storage capabilities, offers improved depiction of the heart, great vessels, other vasculature and adjacent intrathoracic structures in a fashion that is well accepted by clinical colleagues. In order to be successful, however, one must have an understanding of the technology and often unique technical considerations in infants and children. With this familiarity, excellent cardiovascular examinations can be performed even in the most challenging case. (orig.)

    Nuclear medicine plays an important and increasing role in the management of childhood malignancy. This is particularly true in the solid tumours of childhood. It is also helpful in the management of the complications of cancer treatment such as the infections which often accompany immune suppression in oncology patients. Scintigraphy is a complementary investigation to other radiological techniques and adds the functional dimension to anatomical investigations such as CT, MRI and ultrasound. In selected malignancies radionuclides are also used in treatment. This review discusses the technical considerations relating to children and the specific techniques relating to pediatric oncology. Specific tumours and the various applications of radionuclides are discussed in particular lymphoma, primary bone tumours, soft tissue sarcomas, neuroblastoma, Wilms' tumour, brain tumours and leukemia. Uncommon tumours are also discussed and how radionuclides are useful in the investigation of various complications which occur in oncology patients

    Nutrition is central in pediatric care : essential for growth and development, it plays also a role in the prevention of many diseases.Even if breastfeeding is highly recommended, its implementation may be difficult in particular for premature and ill newborns. The creation of a specific unit for breastfeeding support in neonatology allows to help mothers willing to nurse and to improve the rate of breastfeeding for these vulnerable infants.Eating disorders represent an important challenge for patient care. Early detection and rapid management of anorexia is essential for the prognosis. This article describes the challenges and the practical process underlying the development of a practical guideline to manage children and adolescents hospitalized for anorexia.

  11. Moral Hazard in Pediatrics.

    Science.gov (United States)

    Brunnquell, Donald; Michaelson, Christopher M

    2016-07-01

    "Moral hazard" is a term familiar in economics and business ethics that illuminates why rational parties sometimes choose decisions with bad moral outcomes without necessarily intending to behave selfishly or immorally. The term is not generally used in medical ethics. Decision makers such as parents and physicians generally do not use the concept or the word in evaluating ethical dilemmas. They may not even be aware of the precise nature of the moral hazard problem they are experiencing, beyond a general concern for the patient's seemingly excessive burden. This article brings the language and logic of moral hazard to pediatrics. The concept reminds us that decision makers in this context are often not the primary party affected by their decisions. It appraises the full scope of risk at issue when decision makers decide on behalf of others and leads us to separate, respect, and prioritize the interests of affected parties.

    Slovenia, a new country and formerly a part of Yugoslavia, has had its Childrens Hospital in Ljubljana since 1865. This became a part of the University Hospital in 1945, and in the early 1960s the Department of Pediatric Hematology-Oncology was established. The Oncological Institute of Slovenia was established in 1938 and has developed into a modern facility for comprehensive cancer care, research, and teaching. In close cooperation, established in the 1960s, a team from these two institutions takes care of the approximately 60 children per year who develop cancer in Slovenia. Consisting of pediatricians, radiation oncologists, pathologists, cytologists, surgeons, and other ad hoc specialists, the team meets at least twice weekly to plan treatment, follow the patients, discuss the results, and teach. All patients are subject to regular follow-up indefinitely. A separate team has been formed to study the late effects of cancer treatment on survivors, who by now are mostly adults.

    Little information is available concerning the natural history and optimal treatment of chronic nonbacterial osteomyelitis (CNO). We conducted a retrospective review to assess the clinical characteristics and treatment responses of a large cohort of pediatric CNO patients. Children diagnosed with CNO at 3 tertiary care centers in the United States between 1985 and 2009 were identified. Their charts were reviewed, and clinical, laboratory, histopathologic, and radiologic data were extracted. Seventy children with CNO (67% female patients) were identified. Median age at onset was 9.6 years (range 3-17), and median follow-up was 1.8 years (range 0-13). Half of the patients had comorbid autoimmune diseases, and 49% had a family history of autoimmunity. Patients with comorbid autoimmune diseases had more bone lesions (P coexisting autoimmunity was a risk factor for multifocal involvement and treatment with immunosuppressive agents. Disease-modifying antirheumatic drugs and biologics were more likely to lead to clinical improvement than NSAIDs.

    Iopamidol (ISOVUE-370) has been used extensively in adult angiocardiography, but clinical trials in pediatric patients with congenital heart disease are limited. The authors study group comprised 25 children referred for elective cardiac catheterization and cineangiocardiography. Patients were aged 3 months to 15 years (mean, 2 years) and weighted 14-62 kg (mean, 17 kg). Depending on the congenital heart lesion, the total amount of contrast agent injected ranged from 1 to 5 ml/kg. The potential benefits of iopamidol include fewer minor side effects, decreased movement or reaction of the child, and fewer direct effects of contrast agent on biochemical changes, compared with published results of using ionic contrast media. In addition, there were fewer electrocardiographic changes during iopamidol injection, and less change in the end-diastolic pressures after injection compared to results obtained with ionic contrast media. Visual rating of the cineangiograms revealed that all were of diagnostic quality, and 75% were rated as showing ''superior opacification.''

  15. Genetics of pediatric obesity.

    Manco, Melania; Dallapiccola, Bruno

    2012-07-01

    Onset of obesity has been anticipated at earlier ages, and prevalence has dramatically increased worldwide over the past decades. Epidemic obesity is mainly attributable to modern lifestyle, but family studies prove the significant role of genes in the individual's predisposition to obesity. Advances in genotyping technologies have raised great hope and expectations that genetic testing will pave the way to personalized medicine and that complex traits such as obesity will be prevented even before birth. In the presence of the pressing offer of direct-to-consumer genetic testing services from private companies to estimate the individual's risk for complex phenotypes including obesity, the present review offers pediatricians an update of the state of the art on genomics obesity in childhood. Discrepancies with respect to genomics of adult obesity are discussed. After an appraisal of findings from genome-wide association studies in pediatric populations, the rare variant-common disease hypothesis, the theoretical soil for next-generation sequencing techniques, is discussed as opposite to the common disease-common variant hypothesis. Next-generation sequencing techniques are expected to fill the gap of "missing heritability" of obesity, identifying rare variants associated with the trait and clarifying the role of epigenetics in its heritability. Pediatric obesity emerges as a complex phenotype, modulated by unique gene-environment interactions that occur in periods of life and are "permissive" for the programming of adult obesity. With the advent of next-generation sequencing techniques and advances in the field of exposomics, sensitive and specific tools to predict the obesity risk as early as possible are the challenge for the next decade.

    Full Text Available Audience: This scenario was developed to educate emergency medicine residents on the diagnosis and management of a pediatric patient with toxic shock syndrome. The case is also appropriate for teaching of medical students and advanced practice providers, as well as a review of the principles of crisis resource management, teamwork, and communication. Introduction: Toxic shock syndrome is a low-frequency, high-acuity scenario requiring timely identification and aggressive management. If patients suffering from this condition are managed incorrectly, they may progress into multi-organ dysfunction and potentially death. Toxic shock syndrome has been associated with Streptococcus and Staphylococcus aureus (Staph. Approximately half of Staph cases are associated with menstruation, which was first described in the 1970s-1980s and was associated with the use of absorbent tampons.1 Group A Streptococcus may cause complications such as necrotizing fasciitis and gangrenous myositis.2 Pediatric patients may present critically ill from toxic shock syndrome. Providers need to perform a thorough history and physical exam to discern the source of infection. Management requires aggressive care with antibiotics and IV fluids. Objectives: By the end of this simulation session, the learner will be able to: 1 Recognize toxic shock syndrome. 2 Review the importance of a thorough physical exam. 3 Discuss management of toxic shock syndrome, including supportive care and the difference in antibiotic choices for streptococcal and staphylococcal toxic shock syndrome. 4 Appropriately disposition a patient suffering from toxic shock syndrome. 5 Communicate effectively with team members and nursing staff during a resuscitation of a critically ill patient. Method: This session was conducted using high-fidelity simulation, followed by a debriefing session and lecture on toxic shock syndrome.

    Full Text Available Pediatric cardiomyopathies are a group of myocardial diseases with complex taxonomies. Cardiomyopathy can occur in children at any age, and it is a common cause of heart failure and heart transplantation in children. The incidence of pediatric cardiomyopathy is increasing with time. They may be associated with variable comorbidities, which are most often arrhythmia, heart failure, and sudden death. Medical imaging technologies, including echocardiography, cardiac magnetic resonance, and nuclear cardiology, are helpful in reaching a diagnosis of cardiomyopathy. Nevertheless, endomyocardial biopsy is the final diagnostic method of diagnosis. Patients warrant surgical operations, such as palliative operations, bridging operations, ventricular septal maneuvers, and heart transplantation, if pharmaceutical therapies are ineffective. Individual therapeutic regimens due to pediatric characteristics, genetic factors, and pathogenesis may improve the effects of treatment and patients' survival.

    Obesity in childhood is one of the major health issues in pediatric health care today. As expected, the prevalence of obesity-related comorbidities has risen in parallel with that of obesity. Consultation regarding these concomitant diseases and subsequent management by subspecialists, including pediatric gastroenterologists, is now common and has resulted in obesity being recognized as a chronic disease requiring coordination of care. Although medications and even surgery may provide effective, though often temporary, treatments for obesity and its comorbidities, behavioral interventions addressing healthy dietary and physical activity habits remain a mainstay in the obesity treatment paradigm. Therefore, the issue of weight management must be addressed by both general practitioner and subspecialist alike. In this report, we review select aspects of pediatric obesity and obesity-related management issues because it relates in particular to the field of pediatric gastroenterology and hepatology.

  17. New Horizons in Pediatric Psychopharmacology.

    Science.gov (United States)

    Khan, Sarah; Rathore, Vijaylaxmi; Khan, Shahida

    2016-12-01

    Preclinical Research Recent advances in pediatric psychopharmacology have been rather uneven. Increased use of psychotropic drugs among the pediatric population has raised concerns regarding their inappropriate use and safety. While clinical trials have been conducted on various pediatric psychopharmacological drugs, there has been an insignificant amount of importance to innovation in holistic treatment. A rational approach toward elucidating the various challenges would be contingent on the convergence of the development of novel efficacious psychotropic drugs with concrete conceptual frameworks and guidelines fostering enhanced outcomes. A research infrastructure concerning the relevance of the clinician's perspective, combining drugs with alternative therapies, the need for pediatric specific formulations and relevance of these in developing countries provides a basis on which innovative treatment/development can be constructed. The current commentary highlights these comprehensive and targeted treatment guidelines as aspects necessary for building the future of the field.

    Fitz, C.R.; Taylor, G.A.

    1986-01-01

    Extracorporeal membrane oxygenation (ECMO) is a new method of treating respiratory diseases, especially meconium aspiration, in newborns. It requires continued heparinization of the infant and carries the risk of intracranial bleeding. At the author's institution this risk is monitored with daily US examinations. CT is routinely performed at the end of treatment, or at other times to confirm the presence of any pathology that might require the cessation of ECMO treatment. Of the first 62 newborns receiving ECMO therapy, all underwent daily US examinations; 48 underwent CT. In ten patients (16%) hemorrhages developed that were detected on US; the incidence was evenly distributed between primary intraventricular and parenchymal bleeding. Five of these patients died without CT having been performed. Follow-up CT scans in another five also showed hemorrhage. In five patients CT scans showed definite small punctate areas of bleeding in unusual locations, not visible on US. CT scans in another four patients were suspicious for similar bleeding. One subarachnoid hemorrhage was found. In three infants performed widening of the interhemispheric fissure was seen, and six others had probable abnormal widening of the fissure. Overall, 14 (29%) CT scans were definitely abnormal and 21% probably abnormal. Follow-up has not been significantly long enough to allow evaluation the significance of the smaller bleeding areas and interhemispheric fissure widening seen on CT. At this time, both US and CT have a definite role in the care of newborn infants undergoing ECMO

    2001-01-01

    Patient radiation doses during interventional radiology (IR) procedures may reach the thresholds for radiation-induced skin and eye lens injuries. This study investigates the radiation doses received by patients undergoing cerebral embolization. Measurements were conducted using thermoluminescent dosimeters. Radiotherapy verification films were used in order to visualise the radiation field. For each procedure the fluoroscopic and digital dose-area product, the fluoroscopic time, the total number of acquired images and entrance-skin dose calculated by the angiographic unit were recorded. In this paper, the skin, eye and thyroid glands doses on a sample of patients are presented. From a preliminary study of 13 patients having undergone cerebral embolization, it was deduced that six of them have received a dose above 1 Gy. Detailed dose data from patients undergoing IR procedures will be collected in the future with the aim of developing a model to allow estimation of the dose prior to the procedure as well as to look at techniques of dose reduction.

    De La Paz, R.; Enzmann, D.

    1988-01-01

    This paper discusses MRI and CT scanning in the evaluation of AIDS patients with neurological symptoms. MRI is the more sensitive of the two techniques but has poor tissue specificity. Contrast enhancement and identification of tissue calcification on CT scans may improve tissue characterization, but a specific etiological diagnosis may not be possible with either MRI or CT scanning; confirmation by biopsy or the response to treatment is often needed. The finding of multiple focal cerebral lesions on MRI and CT scans usually indicates T. gondii infection. Toxoplasmosis may, however, coexist with primary CNS lymphoma or with fungal, mycobacterial, or viral infection. The presence of a solitary focal cerebral lesion, especially on MRI scans, suggests lymphoma or infection with an agent other than T. gondii. Focal cerebral lesions show a variety of complex signal patterns on MRI and enhancement patterns on CT, none of which are specific for a single etiology. Focal lesions on MRI and CT scans are usually associated with focal neurological deficits, but a significant minority of these lesions, especially those seen on MRI scans, may cause only generalized complaints, such as headache and encephalopathy. MRI and CT are both useful for monitoring therapy and show a reduction in the size, number, and enhancement of lesions with successful treatment. The authors conclude that, owing to its greater sensitivity, MRI appears to be more useful for detecting recurrent disease

  2. Magnetic resonance imaging in neuroradiology

    1990-01-01

    Magnetic resonance imaging (MRI) is now accepted as an effective method of investigating a wide range of disorders, especially of the brain and spine. A short introduction on image contrast in MRI is given and the advantages and disadvantages for the different diseases of the brain is discussed. Excellent soft-tissue contrast, multiplanar imaging capabilities and lack of ionising radiation are conspicuous advantages, and it is now established as the investigation of choice in a large number of clinical conditions, especially when the central nervous system is involved. However, it remains only one of a series of imaging modalities. A confident provisional clinical diagnosis is essential for establishing an imaging protocol and the intention should always be to reach a definitive diagnosis in the least invasive and most cost-effective way. 7 figs., 19 refs

    Full Text Available Jaume Mora1,21Department of Oncology, 2Developmental Tumor Biology Laboratory, Hospital Sant Joan de Deu, Fundacio Sant Joan de Deu, Barcelona, SpainAbstract: Working together with medical oncologists, the question of whether a Ewing sarcoma in a 25-year-old is a pediatric tumor comes up repeatedly. Like Ewing's, some tumors present characteristically at ages that cross over what has been set as the definition of pediatrics (15 years, 18 years, or 21 years?. Pediatric oncology textbooks, surprisingly, do not address the subject of defining a pediatric tumor. They all begin with an epidemiology chapter defining the types of tumors appearing at distinct stages of childhood, adolescence, and young adulthood. Describing the epidemiology of tumors in relation to age, it becomes clear that the disease is related to the phenomenon of aging. The question, however, remains: is there a biological definition of what pediatric age is? And if so, will tumors occurring during this period of life have anything to do with such biological definition? With the aim of finding an objective definition, the fundamental concepts of what defines "pediatrics" was reviewed and then the major features of tumors arising during development were analyzed. The tumors were explored from the perspective of a host immersed in the normal process of growth and development. This physiological process, from pluripotential and undifferentiated cells, makes possible the differentiation, maturation, organization, and function of tissues, organs, and apparatus. A biological definition of pediatric tumors and the infancy–childhood–puberty classification of developmental tumors according to the infancy–childhood–puberty model of normal human development are proposed.Keywords: growth and development, pediatric tumor, infant, childhood and adolescence, pubertal tumors

    Full Text Available History of present illness: A 6-year-old previously healthy male presented to the emergency department with three days of left upper quadrant abdominal pain. Family endorsed one week of fevers, cough productive of yellow sputum, and non-bilious, non-bloody emesis. He denied shortness of breath and chest pain. On exam, the patient was febrile with otherwise normal vital signs. He had diffuse tenderness to his abdomen but clear lungs. Laboratory studies revealed leukocytosis to 25,000/mm3 with a left shift. Significant findings: Upright posterior-anterior plain chest films show a left lower lobe consolidation with an air-fluid level and a single septation consistent with a pulmonary abscess (white arrows. A small left pleural effusion was also present, seen as blunting of the left costophrenic angle and obscuration of the left hemidiaphragm (black arrows. Discussion: Pediatric pulmonary abscesses are rare, most commonly caused by aspiration, and the majority consequently arise in dependent portions of the lung.1 The most common pathogens in children are Streptococcus pneumoniaeand Staphylococcus aureus.1 Immunocompromised patients and those with existing pulmonary disease more commonly contract Pseudomonas aeruginosaor Bacteroides, and fungal pathogens are possible.1 Common symptoms include tachypnea, fever, and cough. Imaging is necessary to distinguish pulmonary abscesses from pneumonia, empyema, pneumatocele, and other etiologies. Plain film radiography may miss up to 18% of pulmonary abscesses yet is often the first modality to visualize an intrathoracic abnormality.2 If seen, pulmonary abscesses most often appear as consolidations with air-fluid levels. Generally, pulmonary abscesses are round with irregular, thick walls, whereas empyemas are elliptical with smooth, thin walls.3 However, these characteristics cannot definitively distinguish these processes.2 Advantages of plain films include being low cost and easily obtained.

  8. Pediatric mandibular fractures.

    Schweinfurth, J M; Koltai, P J

    1998-01-01

    Over the last 20 years, a revolution in the management of facial fractures has taken place. Refinements in biocompatible materials of great delicacy and strength along with advances in our understanding of biomechanics of the face, have rendered complex injuries consistently amenable to accurate 3-dimensional reconstruction. Furthermore, with the availability of education in the techniques of internal rigid fixation, these advanced techniques have become routine practice in adults. However, the suitability of rigid internal fixation for children remains controversial. There are many concerns about the effect of implanted hardware in the mandible of a growing child. In addition, some evidence suggests that the elevation of functional matrix off of bone may result in alterations in development. The goal is to restore the underlying bony architecture to its pre-injury position in a stable fashion, with a minimal of aesthetic and functional impairment. However, in children the treatment of bony injuries is most easily accomplished by techniques that may adversely effect craniofacial development. While it is not entirely possible to resolve this dilemma, there exists an extensive body of experimental and clinical information on the appropriate management of pediatric mandibular fractures which can be used to formulate a rational treatment plan for most cases. This paper presents an overview of the contemporary understanding and application of these treatment principles.

  9. Aromatase inhibitors in pediatrics.

    Science.gov (United States)

    Wit, Jan M; Hero, Matti; Nunez, Susan B

    2011-10-25

    Aromatase, an enzyme located in the endoplasmic reticulum of estrogen-producing cells, catalyzes the rate-limiting step in the conversion of androgens to estrogens in many tissues. The clinical features of patients with defects in CYP19A1, the gene encoding aromatase, have revealed a major role for this enzyme in epiphyseal plate closure, which has promoted interest in the use of inhibitors of aromatase to improve adult height. The availability of the selective aromatase inhibitors letrozole and anastrozole--currently approved as adjuvant therapy for breast cancer--have stimulated off-label use of aromatase inhibitors in pediatrics for the following conditions: hyperestrogenism, such as aromatase excess syndrome, Peutz-Jeghers syndrome, McCune-Albright syndrome and functional follicular ovarian cysts; hyperandrogenism, for example, testotoxicosis (also known as familial male-limited precocious puberty) and congenital adrenal hyperplasia; pubertal gynecomastia; and short stature and/or pubertal delay in boys. Current data suggest that aromatase inhibitors are probably effective in the treatment of patients with aromatase excess syndrome or testotoxicosis, partially effective in Peutz-Jeghers and McCune-Albright syndrome, but probably ineffective in gynecomastia. Insufficient data are available in patients with congenital adrenal hyperplasia or functional ovarian cysts. Although aromatase inhibitors appear effective in increasing adult height of boys with short stature and/or pubertal delay, safety concerns, including vertebral deformities, a decrease in serum HDL cholesterol levels and increase of erythrocytosis, are reasons for caution.

Late Prof. Raman Nair returned in 1954 after training under Dr. Everett Koop in US. Same year, in his far-sighted vision for future development of the speciality, he moved to SATH, Medical College, Trivandrum and started Pediatric surgery as a speciality attached to Paediatrics department; this was the beginning of Pediatric surgery in India. He opted for Pediatric surgery as a full time job and did not do any general surgery work in adults. He was the first full time Pediatric surgeon of India; during the next few years, 2 surgeons, one in Calcutta, Prof. UC Chakraboty and Prof. D Anjaneyulu in Hyderabad started working as full time Pediatric surgeons. In Mumbai, Delhi and Chennai, Pediatric surgery developed much later and then all over the country.

    The pediatric dermatology workforce has not been systematically evaluated since recent changes in board certification requirements. To quantify and characterize the workforce of academic pediatric dermatologists and examine issues related to training, hiring, and retention. Dermatology chairpersons and residency directors in the United States and Canada completed a 30-question survey. Eighty of 132 programs (61%) responded to the survey. More than two thirds of programs (56/80) employed a pediatric dermatologist, and 34 programs were recruiting a pediatric dermatologist. The number of residents that pursue careers in pediatric dermatology is significantly associated with the number of pediatric dermatologists on faculty at their institution. Self-reported data, which may have been reflected by recall bias, and 61% response rate. At a majority of academic centers, the current pool of pediatric dermatology faculty is neither adequate to meet academic nor clinical demands. Methods to increase exposure to pediatric dermatology among medical students and residents must be sought.

    M Imani

    2009-02-01

    Full Text Available Background: The Faculty of Medical Sciences, University of Zahedan implemented the Objective Structured Clinical Examination (OSCE in the final Examination during the 2003–2004 academic year. Simultaneously, the pediatric department initiated faculty and student training, and instituted the OSCE as an assessment instrument during the pediatric clerkship in year 5. The study set out to explore student acceptance of the OSCE as part of an evaluation of the Pediatric clerkship.Purpose: This study implemented to evaluate a new method of assessment in medical education in pediatrics.Methods: A self-administered questionnaire was completed by successive groups of students immediately after the OSCE at the end of each clerkship rotation. Main outcome measures were student perception of examination attributes, which included the quality of instructions and organization, the quality of performance, authenticity and transparency of the process, and usefulness of the OSCE as an assessment instrument compared to other methods.Results: There was overwhelming acceptance of the OSCE in Pediatric with respect to the comprehensiveness (90%, transparency (87%, fairness (57% and authenticity of the required tasks (58–78%. However, students felt that it was a strong anxiety-producing experience. And concerns were expressed regarding the ambiguity of some questions and inadequacy of time for expected tasks.Conclusion: Student feedback was invaluable in influencing faculty teaching, curriculum direction and appreciation of student opinion. Further psychometric evaluation will strengthen the development of the OSCE.Key words: OSCE, COMPETENCE ASSESSMENT

  19. Pediatric interventional radiology: vascular interventions

    Kandasamy, Devasenathipathy; Gamanagatti, Shivanand; Gupta, Arun Kumar

    2016-01-01

    Pediatric interventional radiology (PIR) comprises a range of minimally invasive diagnostic and therapeutic procedures that are performed using image guidance. PIR has emerged as an essential adjunct to various surgical and medical conditions. Over the years, technology has undergone dramatic and continuous evolution, making this speciality grow. In this review, the authors will discuss various vascular interventional procedures undertaken in pediatric patients. It is challenging for the interventional radiologist to accomplish a successful interventional procedure. There are many vascular interventional radiology procedures which are being performed and have changed the way the diseases are managed. Some of the procedures are life saving and have become the treatment of choice in those patients. The future is indeed bright for the practice and practitioners of pediatric vascular and non-vascular interventions. As more and more of the procedures that are currently being performed in adults get gradually adapted for use in the pediatric population, it may be possible to perform safe and successful interventions in many of the pediatric vascular lesions that are otherwise being referred for surgery.

    2011-01-01

    To review the most relevant articles regarding environmental pediatrics, its potential effects on health, and especially its advances in prevention. A literature search was conducted using MEDLINE/PubMed and SciELO databases. Articles from 1990 to 2010 were reviewed, in addition to book chapters related to environmental pediatrics. There is a significant variety of factors that make children highly vulnerable to environmental hazard exposure, which are mainly associated with children's comparatively greater consumption of water, food, and air in relation to body weight. According to the World Health Organization, every year more than 3 million children under the age of 5 die because of environment-related conditions. Approximately 30 to 40% of pediatric diseases are related to environmental factors. Children are constantly exposed to various environmental health hazards, among which the following stand out: contaminated water, lack of adequate sanitation facilities, air pollution, disease vectors, chemical hazards, injuries, and accidents. Nowadays, pediatricians are challenged to address environmental pediatrics health care needs. The pediatric health history needs to be more comprehensive by adding pointed questions to help identify potential environmental risks. Awareness and understanding of the noxious effects of various environmental conditions and knowledge of the related prevention measures will result in timely and adequate interventions that will improve our children's health and development.

    Magnetic resonance imaging (MRI) usage has anecdotally increased due to the principles of ALARA and the desire to Image Gently. Aside from a single abstract in the emergency medicine literature, pediatric emergency department MRI usage has not been described. Our objective was to determine whether MRI use is indeed increasing at a high-volume urban pediatric emergency department with 24/7 MRI availability. Also, we sought to determine which exams, time periods and demographics influenced the trend. Institutional Review Board exemption was obtained. Emergency department patient visit and exam data were obtained from the hospital database for the 2011-2015 time period. MRI usage data were normalized using emergency department patient visit data to determine usage rates. The z-test was used to compare MRI use by gender. The chi-square test was used to test for trends in MRI usage during the study period and in patient age. MRI usage for each hour and each weekday were tabulated to determine peak and trough usage times. MRI usage rate per emergency department patient visit was 0.36%. Headache, pain and rule-out appendicitis were the most common indications for neuroradiology, musculoskeletal and trunk exams, respectively. Usage in female patients was significantly greater than in males (0.42% vs. 0.29%, respectively, P<0.001). Usage significantly increased during the 5-year period (P<0.001). Use significantly increased from age 3 to 17 (0.011% to 1.1%, respectively, P<0.001). Sixty percent of exams were performed after-hours, the highest volume during the 10 p.m. hour and lowest between 4 a.m. and 9 a.m. MRI use was highest on Thursdays and lowest on Sundays (MRI on 0.45% and 0.22% of patients, respectively). MRI use in children increased during the study period, most notably in females, on weekdays and after-hours. (orig.)

  2. Pediatric oncologic emergencies

    1997-01-01

    Oncologic emergencies arise in three ways: disease or therapy induced cytopenias; a space occupying lesion causing pressure on or obstruction of surrounding tissues; or leukemia or tumors creating life-threatening metabolic or hormonal problems. Knowledge of presenting signs and symptoms of these emergencies are essential in pediatric oncologic nursing. Neutropenia opens the door for all manner of infections, but the most life threatening is septicemia progressing to shock. A variety of organisms can cause septic shock in the neutropenic patient, but episodes are most often due to gram-negative organisms and the endotoxins they release. Shock, while still compensated, may present with a elevated or subnormal temperature, flushed, warm, dry skin, widening pulse pressure, tachycardia, tachypnoea and irritability, but without medical intervention will progress to hypo tension, cool, clammy extremities, decreased urinary out- put, and eventually to bradycardia and cardiogenic shock. Another emergency in the cytopenia category is bleeding as a result of thrombocytopenia. Of greatest concern is intracranial hemorrhage that may occur at platelet counts of less than 5,000/mm3. Space-occupying lesions of the chest may produce superior vena cava syndrome (SVGS), pleural and pericardial effusions, and cardiac tamponade. SVGS is most often caused by non-Hodgkin's lymphoma (NHL) and presents as cough, hoarseness, dyspnea, orthopnea and chest pain. Signs include swelling, plethora, cyanosis, edema of conjunctiva and wheezing. Pleural and pericardial effusions present with respiratory or cardiac distress as does cardiac tamponade. Abdominal emergencies arise because of inflammation, mechanical obstruction, hemorrhage (often from steroid induced ulcers), and perforation. Pain is the most common presenting symptom, although vital sign alterations, fever, blood in vomitus or stool, abdominal distension and cessation of flatus are also important components of the acute abdomen

    2008-01-01

    Full Text Available Procedural sedation and analgesia (PSA is an evolving field in pediatric emergency medicine. As new drugs breach the boundaries of anesthesia in the Pediatric Emergency Department, parents, patients, and physicians are finding new and more satisfactory methods of sedation. Short acting, rapid onset agents with little or no lingering effects and improved safety profiles are replacing archaic regimens. This article discusses the warning signs and areas of a patient′s medical history that are particularly pertinent to procedural sedation and the drugs used. The necessary equipment is detailed to provide the groundwork for implementing safe sedation in children. It is important for practitioners to familiarize themselves with a select few of the PSA drugs, rather than the entire list of sedatives. Those agents most relevant to PSA in the pediatric emergency department are presented.

  7. Pediatric obesity & type 2 diabetes.

    Dea, Tara L

    2011-01-01

    This article focuses on (a) identifying obesity and other risk factors for developing type 2 diabetes, (b) differentiating between pediatric type 1 diabetes and type 2 diabetes, and (c) treating pediatric type 2 diabetes. Obesity has significant implications on a child's health, including an increased risk for insulin resistance and progression to type 2 diabetes. Type 2 diabetes in children, characterized by insulin resistance and relative pancreatic b-cell failure due to the increased demand for insulin production, has now reached epidemic proportions. Longitudinal research on pediatric type 2 diabetes, however, is lacking because this epidemic is relatively new. Treatment of type 2 diabetes in children is focused on lifestyle modification with weight management/increased physical activity, and pharmacological management through oral medication or insulin therapy. Because children with type 2 diabetes are at risk for developing diabetes-related complications earlier in life, they need to be closely monitored for comorbidities.

    Full Text Available Claire E Wainwright1,21Royal Children’s Hospital, Brisbane and Queensland, Queensland, Australia; 2Queensland Children’s Medical Research Institute, The University of Queensland, Brisbane, AustraliaThe idea of children as small adults with health care needs that can be managed by extrapolation from adult studies has now largely been abandoned. We now recognize that adult health and disease are closely linked to childhood factors and the critical and ethical importance of clinical research in pediatrics is increasingly being recognized.  While funding and output from pediatric clinical research continues to lag behind health research in adults, particularly in the area of therapeutics, the last decade has thankfully seen a dramatic increase in the number of pediatric studies and particularly randomized controlled clinical trials (RCTs. Since the 1997 Food and Drug Administration (FDA Modernization Act in the United States (US and the subsequent changes in drug registration regulatory systems in the US and Europe, there has been a huge increase in the number of pediatric studies sponsored by pharmaceutical companies. In the United Kingdom, the Medicine for Children’s Research Network was established in 2005 to address the lack of clinical studies in pediatrics. Over the first five years they reported an exciting increase in the number of high quality clinical studies and on their website they have a current portfolio of over 200 pediatric studies, half of which are RCTs and half are sponsored by pharmaceutical companies. Other countries particularly across Europe are also establishing similar programs.

    Epilepsy is a common clinical entity in neurology clinics. The understanding of the genetics of epilepsy has undergone a sea change prompting re-classification by the International league against epilepsy recently. The prevalence rates of epilepsy in India are similar to those of developed nations. However, the large treatment gap is a major challenge to our public health system. Perinatal injuries are a major causative factor in pediatric group. We have discussed a few common etiologies such as neurocysticercosis and newer genetic epilepsy syndromes. We have also briefly touched upon the Indian experience in pediatric epilepsy surgery.

    We describe the risk management of pediatric anesthesia. The most important risk management of pediatric anesthesia is airway and temperature management. Neonates and infants easily become hypoxic due to their insufficient functional residual capacity. Therefore airway management is most important not only during induction of anesthesia but also during maintenance of anesthesia and extubation. The management of patients' temperature, including control of room temperature should be taken into consideration. In addition, careful attention should be paid not to introduce air bubbles in any lines, especially in patients with congenital heart diseases.

    The National Health and Nutrition Examination Survey from the Centers for Disease Control and Prevention reports a steady increase in obesity over the last 30 years. The greatest increase was seen in 15 to 19 year olds, whose obesity prevalence almost doubled from 10.5% to 19.4%. The solution to pediatric obesity requires a multidisciplinary approach addressing cultural norms, technologic advances, and family engagement. Future treatment strategies to combat the obesity epidemic will have to extend beyond the health care provider's office. Behavior modification remains the key component to pediatric obesity prevention and treatment. Published by Elsevier Inc.

    Delirium occurs frequently in the critically ill child. It is a syndrome characterized by an acute onset and fluctuating course, with behaviors that reflect a disturbance in awareness and cognition. Delirium represents global cerebral dysfunction due to the direct physiologic effects of an underlying medical illness or its treatment. Pediatric delirium is strongly associated with poor outcomes, including increased mortality, prolonged intensive care unit length of stay, longer time on mechanical ventilation, and increased cost of care. With heightened awareness, the pediatric intensivist can detect, treat, and prevent delirium in at-risk children. Copyright © 2017 Elsevier Inc. All rights reserved.

    Tuberculosis in childhood is clinically challenging, but it is a preventable and treatable disease. Risk factors depend on age and immunity status. The most common form of pediatric tuberculosis is pulmonary disease, which comprises more than half of the cases. Other forms make up the extrapulmonary tuberculosis that involves infection of the lymph nodes, central nervous system, gastrointestinal system, hepatobiliary tree, and renal and musculoskeletal systems. Knowledge of the imaging characteristics of pediatric tuberculosis provides clues to diagnosis. This article aims to review the imaging characteristics of common sites for extrapulmonary tuberculous involvement in children.

    Hydrocephalus develops in up to 90% of patients born with myelomeningocele. Although endoscopic third ventriculostomy (ETV) is currently considered the preferred treatment for obstructive hydrocephalus, its results have been inconsistent in patients with myelomeningocele. This study focuses on clinical and radiologic outcomes of ETV in children with hydrocephalus related to myelomeningocele. Medical records of 18 pediatric patients with myelomeningocele treated with ETV from 1998 to 2015 at the Centro Hospitalar São João (Porto, Portugal) were reviewed retrospectively. Patients' caregivers were contacted to evaluate their clinical manifestations before and after surgery regarding signs and symptoms of hydrocephalus and Chiari malformation. Control neuroradiologic imaging of 9 patients was obtained and analyzed. Success of ETV was defined by clinical resolution and radiologic confirmation. ETV was successful in 8 of 18 cases (44.4%). Groups of patients were compared according to age at the time of surgery, with a 40% (2/5) success rate in newborns and a 50% success rate (3/6) in children older than 1 year. Eight patients underwent ETV as a first option, with a 37.5% success rate. Ten patients underwent the procedure after previous ventriculoperitoneal shunt (VPS), 5 for malfunction and 5 for VPS infection with 60% and 40% success rates, respectively. Early postoperative complications occurred in 2 patients. ETV can be performed in patients with myelomeningocele and hydrocephalus with success rates of almost 50%. Prior VPS or VPS malfunction or infection do not contraindicate ETV. If possible, the procedure should be delayed until the patient is at least 1 month old. Copyright © 2017 Elsevier Inc.

    Abstract The classification of central nervous system (CNS) tumors into clinically and biologically distinct entities and subgroups is challenging. Children and adolescents can be affected by >100 histological variants with very variable outcomes, some of which are exceedingly rare. The current WHO classification has introduced a number of novel molecular markers to aid routine neuropathological diagnostics, and DNA methylation profiling is emerging as a powerful tool to distinguish CNS tumor classes. The Molecular Neuropathology 2.0 study aims to integrate genome wide (epi-)genetic diagnostics with reference neuropathological assessment for all newly-diagnosed pediatric brain tumors in Germany. To date, >350 patients have been enrolled. A molecular diagnosis is established by epigenetic tumor classification through DNA methylation profiling and targeted panel sequencing of >130 genes to detect diagnostically and/or therapeutically useful DNA mutations, structural alterations, and fusion events. Results are aligned with the reference neuropathological diagnosis, and discrepant findings are discussed in a multi-disciplinary tumor board including reference neuroradiological evaluation. Ten FFPE sections as input material are sufficient to establish a molecular diagnosis in >95% of tumors. Alignment with reference pathology results in four broad categories: a) concordant classification (~77%), b) discrepant classification resolvable by tumor board discussion and/or additional data (~5%), c) discrepant classification without currently available options to resolve (~8%), and d) cases currently unclassifiable by molecular diagnostics (~10%). Discrepancies are enriched in certain histopathological entities, such as histological high grade gliomas with a molecularly low grade profile. Gene panel sequencing reveals predisposing germline events in ~10% of patients. Genome wide (epi-)genetic analyses add a valuable layer of information to routine neuropathological

    2016-03-01

    Programs provided by the Korea Association of Cardiopulmonary Resuscitation include Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), Pediatric Advanced Life Support (PALS), and Korean Advanced Life Support (KALS). However, programs pertinent to dental care are lacking. Since 2015, related organizations have been attempting to develop a Dental Advanced Life Support (DALS) program, which can meet the needs of the dental environment. Generally, for initial management of emergency situations, basic life support is most important. However, emergencies in young children mostly involve breathing. Therefore, physicians who treat pediatric dental patients should learn PALS. It is necessary for the physician to regularly renew training every two years to be able to immediately implement professional skills in emergency situations. In order to manage emergency situations in the pediatric dental clinic, respiratory support is most important. Therefore, mastering professional PALS, which includes respiratory care and core cases, particularly upper airway obstruction and respiratory depression caused by a respiratory control problem, would be highly desirable for a physician who treats pediatric dental patients. Regular training and renewal training every two years is absolutely necessary to be able to immediately implement professional skills in emergency situations.

  20. Pediatric glaucoma: current perspectives

    Full Text Available Giorgio Marchini, Marco Toscani, Francesca Chemello Eye Clinic, Department of Neurological and Movement Sciences, University of Verona, Verona, Italy Abstract: “Childhood glaucoma” is a heterogeneous group of severe pediatric conditions often associated with significant visual loss and characterized by elevated intraocular pressure (IOP and optic-disk cupping. Successful IOP control is crucial but challenging and most often achieved surgically, with medical therapy playing a supportive role. There are many classifications of childhood glaucoma, but they can simply be divided into primary, in which a developmental abnormality of the anterior chamber angle only exists, and secondary, in which aqueous outflow is reduced due to independent mechanisms that secondarily impair the function of the filtration angle. The worldwide prevalence of childhood blindness ranges from 0.03% in high-income countries to 0.12% in undeveloped countries. The majority of cases do not have an identified genetic mutation and, where the mutation is known, the genes often account for only a small proportion of cases. Several pathogenetic mechanisms are known to contribute to the development of childhood glaucoma. Whatever the cause, it results in a reduced aqueous outflow at the level of the trabecular meshwork. Age of onset and magnitude of the elevated IOP largely determine the clinical manifestation the high variability of clinical manifestations. Glaucoma from any cause in a neonate and infant is characterized by the classic triad of epiphora, photophobia, and blepharospasm, and could be associated with eye enlargement (buphthalmos and Haab striae. The eye examination, usually performed under general anesthesia, includes: tonometry, anterior-segment examination, gonioscopy, corneal diameter and axial length measurement, dilated fundoscopy with optic-nerve-head evaluation. Medical therapy, considering the high frequency of side effects, is generally used as

  1. Pediatric sexology and hermaphroditism.

    1985-01-01

    Lacking an empirically based theory of erotosexual development and health in childhood, pediatrics too easily falls back on reductionistic hypotheses of the nature versus nurture type. A new, three-term paradigm, namely, nature/critical-period/nurture, is needed to explain, for example, the phenomenology of hermaphroditism, and the differentiation of gender-identity/role (G-I/R) in individual cases. In 30 young women with a history of the early-treated, 46,XX congenital virilizing adrenal hyperplasia (CVAH) syndrome, 37% (N = 11) had a history of bisexual imagery or practice, as compared with 7% in the control patients (chi 2 = 17.7; p less than .001); and 5 of these 11 rated themselves as exclusively or predominantly lesbian. In Kinsey's sample, 15% of females reported homoerotic imagery by age 20, and 2 out of 3 of them also had homoerotic partner contact. The CVAH finding may be a function of prenatal and/or neonatal brain androgenization, but other variables, such as the history of juvenile erotosexual rehearsal play, cannot be ruled out. Among adolescents with a history of hermaphroditism, sex-reassignment applications are honored predominantly if they are made by 46,XY hermaphrodites assigned neonatally as girls and with nonfeminizing hormonal puberty, as medical and folk traditions both favor approval of such applicants more than others. Parthenogenic whiptail lizards that alternately simulate the male and female mating behavior of related diecious species provide an animal model that demonstrates the existence of both male and female sexual schemas in the same brain. In human beings, the irreducible sex differences are that males impregnate, and females menstruate, gestate, and lactate. Otherwise, sexual dimorphism that is programmed into the brain under the influence of prenatal hormones appears to be not sex-irreducible, but sex-shared and threshold-dimorphic. A complete theory of the differentiation of all the constituents of masculinity or femininity of

    2018-04-01

    Full Text Available Phantom limb pain (PLP is a prevalent problem for children and adolescents undergoing amputation due to cancer treatment. The symptoms are wide ranging from sharp to tingling. PLP in children typically lasts for a few minutes but can be almost constant and can be highly distressing. This focused review describes the characteristics, epidemiology, mechanisms, and evidence-based treatment of PLP in pediatric populations, focusing on pediatric cancer. In pediatric oncology, the administration of chemotherapy is a risk factor that potentially sensitizes the nervous system and predisposes pediatric cancer patients to develop PLP after amputation. Gabapentin, tricyclic antidepressants, opiates, nerve blocks, and epidural catheters have shown mixed success in adults and case reports document potential utility in pediatric patients. Non-pharmacologic treatments, such as mirror therapy, psychotherapy, and acupuncture have also been used in pediatric PLP with success. Prospective controlled trials are necessary to advance care for pediatric patients with PLP.

    Presentation of suspected pediatric uveitis: Pediatric uveitis is usually managed in specialized ophthalmic centers in the UK. Meaningful data acquisition in these clinics may be helpful in clinical governance, and healthcare planning in a specialty that is gradually changing due to changes in treatment choices. Retrospective analysis of prospectively acquired data in the Liverpool pediatric uveitis database was performed. Analysis of our data, based on 147 patients, with a mean age of 10 years, indicated a female to male ratio of 2:1. 99% of patients were Caucasian. Our data indicates 86% of all patients attending the uveitis clinic were diagnosed with juvenile idiopathic arthritis, followed by intermediate uveitis 5% and idiopathic uveitis 4%. 46% of patients required treatment. Systemic treatment included methotrexate (34%), prednisolone (14%), etanercept (6%), ciclosporin (6%), mycophenolate (3%), and infliximab (1%). Severe visual loss (defined by counting fingers or below vision) was seen in 10 eyes despite appropriately treated chronic uveitis. Our data shows uveitis-related ocular morbidity in a predominantly pediatric Caucasian population. Patients with severe and chronic uveitis may experience significant uveitis-related complications and subsequent visual loss despite aggressive treatment.

    2013-03-01

    Full Text Available Background and Need for Novel Biomarkers: Brain tumors are the leading cause of death by solid tumors in children. Although improvements have been made in their radiological detection and treatment, our capacity to promptly diagnose pediatric brain tumors in their early stages remains limited. This contrasts several other cancers where serum biomarkers such as CA 19-9 and CA 125 facilitate early diagnosis and treatment. Aim: The aim of this article is to review the latest literature and highlight biomarkers which may be of clinical use in the common types of primary pediatric brain tumor. Methods: A PubMed search was performed to identify studies reporting biomarkers in the bodily fluids of pediatric patients with brain tumors. Details regarding the sample type (serum, cerebrospinal fluid or urine, biomarkers analyzed, methodology, tumor type and statistical significance were recorded. Results: A total of 12 manuscripts reporting 19 biomarkers in 367 patients vs. 397 controls were identified in the literature. Of the 19 biomarkers identified, 12 were isolated from cerebrospinal fluid, 2 from serum, 3 from urine, and 2 from multiple bodily fluids. All but one study reported statistically significant differences in biomarker expression between patient and control groups.Conclusions: This review identifies a panel of novel biomarkers for pediatric brain tumors. It provides a platform for the further studies necessary to validate these biomarkers and, in addition, highlights several techniques through which new biomarkers can be discovered.

    2014-07-01

    Pediatric hospital medicine (PHM) is moving toward becoming an American Board of Pediatrics (ABP) subspecialty, roughly a decade after its formal inception in 2003. Education has played a central role as the field has evolved. Hospitalists are needed to educate trainees, medical students, residents, fellows, and nurse practitioner and physician assistant students in inpatient pediatric practice. Continuous professional development is needed for hospitalists currently in practice to augment clinical skills, such as providing sedation and placing peripherally inserted central catheter lines, and nonclinical skills in areas such as quality improvement methodology, hospital administration, and health service research. To address the educational needs of the current and future state of PHM, additional training is now needed beyond residency training. Fellowship training will be essential to continue to advance the field of PHM as well as to petition the ABP for specialty accreditation. Training in using adult educational theory, curriculum, and assessment design are critical for pediatric hospitalists choosing to advance their careers as clinician-educators. Several venues are available for gaining advanced knowledge and skill as an educator. PHM clinician-educators are advancing the field of pediatric education as well as their own academic careers by virtue of the scholarly approach they have taken to designing and implementing curricula for unique PHM teaching situations. PHM educators are changing the educational paradigm to address challenges to traditional education strategies posed by duty hour restrictions and the increasing drive to shorten the duration of the hospitalization. By embracing learning with technology, such as simulation and e-learning with mobile devices, PHM educators can address these challenges as well as respond to learning preferences of millennial learners. The future for PHM education is bright. Copyright 2014, SLACK Incorporated.

    2015-01-01

    The use of simulation-based medical education (SBME) in pediatrics has grown rapidly over the past 2 decades and is expected to continue to grow. Similar to other instructional formats used in medical education, SBME is an instructional methodology that facilitates learning. Successful use of SBME in pediatrics requires attention to basic educational principles, including the incorporation of clear learning objectives. To facilitate learning during simulation the psychological safety of the participants must be ensured, and when done correctly, SBME is a powerful tool to enhance patient safety in pediatrics. Here we provide an overview of SBME in pediatrics and review key topics in the field. We first review the tools of the trade and examine various types of simulators used in pediatric SBME, including human patient simulators, task trainers, standardized patients, and virtual reality simulation. Then we explore several uses of simulation that have been shown to lead to effective learning, including curriculum integration, feedback and debriefing, deliberate practice, mastery learning, and range of difficulty and clinical variation. Examples of how these practices have been successfully used in pediatrics are provided. Finally, we discuss the future of pediatric SBME. As a community, pediatric simulation educators and researchers have been a leading force in the advancement of simulation in medicine. As the use of SBME in pediatrics expands, we hope this perspective will serve as a guide for those interested in improving the state of pediatric SBME. Published by Elsevier Inc.

    2016-01-01

    Study Objectives: Obstructive sleep apnea (OSA) is a common pediatric condition characterized by recurrent partial or complete cessation of airflow during sleep, typically due to inadequate upper airway patency. Continuous positive airway pressure (CPAP) is a therapeutic option that reduces morbidity. Despite efforts to promote use, CPAP adherence is poor in both pediatric and adult populations. We sought to determine whether demographics, insurance status, OSA severity, therapeutic pressure, or comorbid conditions were associated with pediatric CPAP adherence. Methods: A retrospective review of adherence download data was performed on all pediatric patients with initiation or adjustment of CPAP treatment over a one-year period with documented in-laboratory CPAP titration. Patients were grouped as CPAP adherent or non-adherent, where adherence was defined as > 70% nightly use and average usage ≥ 4 hours per night. Differences between the groups were analyzed by χ2 test. Results: Overall, nearly half of participants were CPAP adherent (49%, 69/140). Of the demographic data collected (age, ethnicity, sex, insurance status), only female sex was associated with better adherence (60.9% vs 39.5% of males adherent; odds ratio [OR] = 2.41, 95%CI = 1.20–4.85; p = 0.01). Severity of OSA (diagnostic apnea-hypopnea index [AHI] and degree of hypoxemia), therapeutic pressure, and residual AHI did not impact CPAP adherence (p > 0.05). Patients with developmental delay (DD) were more likely to be adherent with CPAP than those without a DD diagnosis (OR = 2.55, 95%CI = 1.27–5.13; p = 0.007). Female patients with trisomy 21 tended to be more adherent, but this did not reach significance or account for the overall increased adherence associated with female sex. Conclusions: Our study demonstrates that adherence to CPAP therapy is poor but suggests that female sex and developmental delay are associated with better adherence. These findings support efforts to understand the

  9. Social Media in Pediatric Orthopaedics.

    Lander, Sarah T; Sanders, James O; Cook, Peter C; O'Malley, Natasha T

    Internet searches and social media utilization in health care has exploded over the past 5 years, and patients utilize it to gain information on their health conditions and physicians. Social media has the potential to serve as a means for education, communication, and marketing in all health care specialties. Physicians are sometimes reluctant to engage because of concerns of privacy, litigation, and lack of experience with this modality. Many surgical subspecialties have capitalized on social media but no study to date has examined the specific footprint of pediatric orthopaedic surgeons in this realm. We aim to quantify the utilization of individual social media platforms by pediatric orthopaedic surgeons, and identify any differences between private and hospital-based physicians, but also regional differences. Using the Pediatric Orthopaedic Society of North America Member Directory, each active member's social media presence was reviewed through an Internet search. Members were stratified on the basis of practice model and geographic location. Individual Internet searches, social media sites, and number of publications were reviewed for social media presence. Of 987 Pediatric Orthopaedic Society of North America members, 95% had a professional webpage, 14.8% a professional Facebook page, 2.2% a professional Twitter page, 36.8% a LinkedIn profile, 25.8% a ResearchGate profile, 33% at least 1 YouTube. Hospital-based physicians had a lower mean level of utilization of social media compared with their private practice peers, and a higher incidence of Pubmed publications. Private practice physicians had double the social media utilization. Regional differences reveal that practicing Pediatric Orthopaedists in the Northeast had increased utilization of ResearchGate and LinkedIn and the West had the lowest mean social media utilization levels. The rapid expansion of social media usage by patients and their family members is an undeniable force affecting the health

    End-stage heart failure affects thousands of children yearly and mechanical circulatory support is used at many points in their care. Extracorporeal membrane oxygenation supports both the failing heart and lungs, which has led to its use as an adjunct to cardiopulmonary resuscitation as well as in post-operative cardiogenic shock. Continuous-flow ventricular assist devices (VAD) have replaced pulsatile-flow devices in adults and early studies have shown promising results in children. The Berlin paracorporeal pulsatile VAD recently gained U.S. Food and Drug Administration approval and remains the only VAD approved in pediatrics.

    2015-01-01

    The prevalence of child and adolescent obesity in the United States increased dramatically between 1970 and 2000, and there are few indications that the rates of childhood obesity are decreasing. Obesity is associated with myriad medical, psychological, and neurocognitive abnormalities that impact children’s health and quality of life. Genotypic variation is important in determining the susceptibility of individual children to undue gains in adiposity; however, the rapid increase in pediatric obesity prevalence suggests that changes to children’s environments and/or to their learned behaviors may dramatically affect body weight regulation. This paper presents an overview of the epidemiology, consequences, and etiopathogenesis of pediatric obesity, serving as a general introduction to the subsequent papers in this Special Issue that address aspects of childhood obesity and cognition in detail.

    Virtual reality (VR) technologies allow for controlled simulations of affectively engaging background narratives. These virtual environments offer promise for enhancing emotionally relevant experiences and social interactions. Within this context, VR can allow instructors, therapists, neuropsychologists, and service providers to offer safe, repeatable, and diversifiable interventions that can benefit assessments and learning in both typically developing children and children with disabilities. Research has also pointed to VR's capacity to reduce children's experience of aversive stimuli and reduce anxiety levels. Although there are a number of purported advantages of VR technologies, challenges have emerged. One challenge for this field of study is the lack of consensus on how to do trials. A related issue is the need for establishing the psychometric properties of VR assessments and interventions. This review investigates the advantages and challenges inherent in the application of VR technologies to pediatric assessments and interventions.

    2009-04-01

    Difficulty swallowing or dysphagia can be present in children and adults alike. Pediatric dysphagias have long been recognized in the literature. Certain groups of infants with specific developmental and/or medical conditions have been identified as being at high risk for developing dysphagia. Still others may present with a swallowing or feeding problem as their primary symptom. Left untreated, these problems in infants and children can lead to failure to thrive, aspiration pneumonias, gastroesophageal reflux, and/or the inability to establish and maintain proper nutrition and hydration. Awareness of the prevalence of pediatric dysphagia in today's population and the signs and symptoms of this condition aids in its treatment. Early detection of dysphagia in infants and children is important to prevent or minimize complications. This article provides a review of symptoms, etiologies, and resources available regarding management of this condition to help the primary care physician and the families of young children and infants in its management.

    2016-05-01

    The terms gender and sexuality, once rarely discussed in a public forum, are now dominant topics of conversation on social media, in all forms of entertainment, politics, law, and medicine. The pediatric primary care physician, like all people and institutions involved in the delivery of health care, must be diligent about providing compassionate and competent care to patients and families contending with gender issues. The complex variety of obstacles these patients may face require a well-informed, sensitive clinician who can offer sound medical advice and appropriate referral. This article guides pediatricians through some of the challenges related to gender identity so they can assist their patients in navigating through any difficulties.

    2011-09-01

    Full Text Available Abstract Although musculoskeletal ultrasound (MSUS has emerged as an indispensible tool among physicians involved in musculoskeletal medicine in the last two decades, only recently has it become more attractive to pediatric rheumatologists. Thereafter, the use of MSUS in pediatric rheumatology has started to increase. Yet, an ever-growing body of literature shows parity and even superiority of MSUS when compared to physical examination and other imaging modalities. MSUS is suitable for examination of children of all ages and it has certain advantages over other imaging modalities; as it is cheaper, mobile, instantly accessible bedside, easy to combine with clinical assessment (interactivity and non-invasive. It does not require sedation, which facilitates repetitive examinations. Assessment of multiple locations is possible during the same session. Agitation is rarely a problem and small children can be seated in their parents' lap or they can even play while being examined.

    The aim of this study was to evaluate whether the current state of child neurology education during pediatric residency provides adequate preparation for pediatric practice. A survey was sent to recent graduates from 3 pediatric residency programs to assess graduate experience, perceived level of competence, and desire for further education in child neurology. Responses from generalists versus subspecialists were compared. The response rate was 32%, half in general pediatric practice. Only 22% feel very confident in approaching patients with neurologic problems. This may represent the best-case scenario as graduates from these programs had required neurology experiences, whereas review of Accreditation Council of Graduate Medical Education-accredited residency curricula revealed that the majority of residencies do not. Pediatric neurologic problems are common, and pediatric residency graduates do encounter such problems in practice. The majority of pediatricians report some degree of confidence; however, some clear areas for improvement are apparent.

    To review the demographics and workload characteristics of pediatric neurology in Canada. A standardized survey questionnaire was mailed out to practicing pediatric neurologists in Canada in 2001. Variables examined were age, gender, hours on call, regular hours worked per week, type of practice and projected changes in practice over next five to ten years. Results were compared to the 1994 Pediatric Neurology Manpower Survey which had used the same survey instrument. Fifty-six (70%) pediatric neurologists practicing in Canada returned the survey. As was the case in 1994, no significant differences in workload were found based on age or gender. The average age of the practicing pediatric neurologist in 2001 was 51 years compared to 45 years in 1994. The proportion of physicians over 55 years in 2001 was 35% compared to 25% in 1994. Pediatric neurology in Canada is an aging specialty needing a significant recruitment of new members

    Pediatric urolithiasis is an important and increasingly prevalent cause of pediatric morbidity and hospital admission. Ultrasound (US) is the recommended primary imaging modality for suspected urolithiasis in children. There is, however, widespread use of CT as a first-line study for abdominal pain in many institutions involved in pediatric care. The objective of this review is to outline state-of-the-art imaging modalities and methods for diagnosing urolithiasis in children. The pediatric radiologist plays a key role in ensuring that the appropriate imaging modality is performed in the setting of suspected pediatric urolithiasis. Our proposed imaging algorithm starts with US, and describes the optimal technique and indications for the use of CT. We emphasize the importance of improved communication with a greater collaborative approach between pediatric and general radiology departments so children undergo the appropriate imaging evaluation.

    2009-01-01

    Traumatic dental injuries are very frequent during childhood and adolescence. In fact, 2 out of 3 children have suffered a traumatic dental injury before adulthood. This fact links dental traumatology to pediatric dentistry. Unfortunately, this is not reflected by active participation by pediatric...... dentists in acute treatment, follow-up, and research. To examine the status of pediatric dentistry in relation to dental trauma, a publication analysis was undertaken in 1980, 1990, 2000, and 2007 about trauma articles published in 4 pediatric journals: journal of Dentistry for Children, Pediatric...... Dentistry, The journal of Pedodontics, and the International journal of Pediatric Dentistry. This study shows an average publication rate of trauma articles of approximately 3 percent of all articles published and with no improvement in later decennia. If only clinical studies are considered (leaving out...

    Helicopter Emergency Medical Services (HEMS) have been designed to provide faster access to trauma center care in cases of life-threatening injury. However, the ideal recipient population is not fully characterized, and indications for helicopter transport in pediatric trauma vary dramatically by county, state, and region. Overtriage, or unnecessary utilization, can lead to additional patient risk and expense. In this study we perform a nationwide descriptive analysis of HEMS for pediatric trauma and assess the incidence of overtriage in this group. We reviewed records from the American College of Surgeons National Trauma Data Bank (2008-11) and included patients less than 16 years of age who were transferred from the scene of injury to a trauma center via HEMS. Overtriage was defined as patients meeting all of the following criteria: Glasgow Coma Scale (GCS) equal to 15, absence of hypotension, an Injury Severity Score (ISS) less than 9, no need for procedure or critical care, and a hospital length of stay of less than 24 hours. A total of 19,725 patients were identified with a mean age of 10.5 years. The majority of injuries were blunt (95.6%) and resulted from motor vehicle crashes (48%) and falls (15%). HEMS transported patients were predominately normotensive (96%), had a GCS of 15 (67%), and presented with minor injuries (ISS<9, 41%). Overall, 28 % of patients stayed in the hospital for less than 24 hours, and the incidence of overtriage was 17%. Helicopter overtriage is prevalent among pediatric trauma patients nationwide. The ideal model to predict need for HEMS must consider clinical outcomes in the context of judicious resource utilization. The development of guidelines for HEMS use in pediatric trauma could potentially limit unnecessary transfers while still identifying children who require trauma center care in a timely fashion.

    Recent reports note a dramatic increase in the number of pediatric trampoline injuries (PTI) during the past several years. In 1996, the US Consumer Product Safety Commission estimates that 83 000 patients received treatment for trampoline injuries in US hospital emergency departments (EDs), and that approximately 75% of these patients were trampolines accounted for 99% of PTI. Most injuries (66%) occurred on the trampoline, 28% resulted from falls off, and 4% from imaginative mechanisms. One hundred eleven patients (15%) suffered severe injury (1990 Abbreviated Injury Scale value >/=3), usually of an extremity (89 out of 111). Fractures occurred in 324 patients (45%). Spinal injuries were common (12%), including 7 patients with cervical or thoracic fractures, and 1 with C7 paraplegia. Fractures were more frequently associated with falls off the trampoline, whereas spinal injuries more frequently occurred on the trampoline. Eighty patients (11%) required prehospital medical transport to our ED, 584 (80%) had ED radiographs, and 382 (53%) required pediatric surgical subspecialty involvement. Seventeen percent of PTI patients (125 out of 727) were admitted to the hospital, including 9 to the pediatric intensive care unit; 99 (14%) required one or more operations. Mean hospital stay was 2 days (range, 1-63 days); 24 stays (19%) were for >/=3 days. We estimate that the hospital charges for the acute medical care of PTI study patients at our institution totaled approximately $700 000. PTI are dramatically increasing in number, and result in considerable childhood morbidity. Most PTI occur on privately owned trampolines. Few, if any, safety recommendations for the trampoline are followed. We support recommendations for a ban on the recreational, school, and competitive pediatric use of trampolines.

    Limited access to tertiary-level health care, limited trained pediatric nephrologists and transplant physicians, lack of facilities for dialysis, lack of an effective deceased donor program, non-affordability, and non-adherence to immunosuppressant drugs poses a major challenge to universal availability of pediatric transplantation in developing countries. We present the results of a survey which, to the best of our knowledge, is the first such published attempt at understanding the current state of pediatric renal transplantation in India. A designed questionnaire formulated by a group of pediatric nephrologists with the aim of understanding the current practice of pediatric renal transplantation was circulated to all adult and pediatric nephrologists of the country. Of 26 adult nephrologists who responded, 16 (61.5%) were involved in pediatric transplantation, and 10 of 15 (66.6%) pediatric nephrologists were involved in pediatric transplantation. Most of the centers doing transplants were private/trust institution with only three government institutions undertaking it. Induction therapy was varied among pediatric and adult nephrologists. There were only a few centers (n=5) in the country routinely doing >5 transplants per year. Preemptive transplants and protocol biopsies were a rarity. The results demonstrate lower incidence of undertaking pediatric transplants in children below 6 years, paucity of active cadaveric programs and lack of availability of trained pediatric nephrologists and staff. In contrast to these dissimilarities, the immunosuppressant use seems to be quite similar to Western registry data with majority favoring induction agent and triple immunosuppressant (steroid, mycophenolate mofetil and tacrolimus) for maintenance. The survey also identifies major concerns in availability of this service to all regions of India as well as to all economic segments. © 2017 John Wiley & Sons A/S.

    Bösenberg, Adrian T

    2007-06-01

    To highlight the problems faced in developing countries where healthcare resources are limited, with particular emphasis on pediatric anesthesia. The fact that very few publications address pediatric anesthesia in the developing world is not surprising given that most anesthetics are provided by nonphysicians, nurses or unqualified personnel. In compiling this article information is drawn from pediatric surgical, anesthetic and related texts. In a recent survey more than 80% of anesthesia providers in a poor country acknowledged that with the limited resources available they could not provide basic anesthesia for children less than 5 years. Although many publications could be regarded as anecdotal, the similarities to this survey suggest that the lack of facilities is more generalized than we would like to believe. The real risk of anesthesia in comparison to other major health risks such as human immunodeficiency virus, malaria, tuberculosis and trauma remains undetermined. The critical shortage of manpower remains a barrier to progress. Despite erratic electrical supplies, inconsistent oxygen delivery, paucity of drugs or equipment and on occasion even lack of running water, many provide life-saving anesthesia. Perioperative morbidity and mortality is, however, understandably high by developed world standards.

    The aim of our study was to evaluate our liver transplant pediatric patients and to report our experience in the complications and the long-term follow-up results. Patients between the ages of 0 and 18 years, who had liver transplantation in the organ transplantation center of our university hospital between 1997 and 2016, were included in the study. The age, sex, indications for the liver transplantation, complications after the transplantation, and long-term follow-up findings were retrospectively evaluated. The obtained results were analyzed with statistical methods. In our organ transplantation center, 62 pediatric liver transplantations were carried out since 1997. The mean age of our patients was 7.3 years (6.5 months-17 years). The 4 most common reasons for liver transplantation were: Wilson's disease (n=10; 16.3%), biliary atresia (n=9; 14.5%), progressive familial intrahepatic cholestasis (n=8; 12.9%), and cryptogenic cirrhosis (n=7; 11.3%). The mortality rate after transplantation was 19.6% (12 of the total 62 patients). The observed acute and chronic rejection rates were 34% and 4.9%, respectively. Thrombosis (9.6%) was observed in the hepatic artery (4.8%) and portal vein (4.8%). Bile leakage and biliary stricture rates were 31% and 11%, respectively. 1-year and 5-year survival rates of our patients were 87% and 84%, respectively. The morbidity and mortality rates in our organ transplantation center, regarding pediatric liver transplantations, are consistent with the literature.

    Our goal was to describe the spectrum of clinical phenotypes, laboratory and imaging features, and treatment in pediatric patients with neuromyelitis optica. The study consisted of a retrospective chart review of patients followed in a pediatric multiple sclerosis center with a diagnosis of neuromyelitis optica spectrum disorder. Nine patients with neuromyelitis optica spectrum disorders were included, all of whom were female. There were 4 black children, 2 Latin American children, 2 white children, and 1 child of mixed Latin American/white heritage. Median age at initial attack was 14 years (range: 1.9-16 years). Median disease duration was 4 years (range: 0.6-9 years). Tests for neuromyelitis optica immunoglobulin G were positive for 7 patients. Eight patients had transverse myelitis and optic neuritis, and 1 patient had longitudinally extensive transverse myelitis without optic neuritis but had a positive neuromyelitis optica immunoglobulin G antibody titer. Cerebral involvement on MRI was found in all subjects, 5 of whom were symptomatic with encephalopathy, seizures, hemiparesis, aphasia, vomiting, or hiccups. Immunosuppressive therapy reduced attack frequency and progression of disability. Pediatric neuromyelitis optica has a diverse clinical presentation and may be difficult to distinguish from multiple sclerosis in the early stages of the disease. The recognition of the broad spectrum of this disease to include signs and symptoms of brain involvement is aided by the availability of a serum biomarker: neuromyelitis optica immunoglobulin G. Early diagnosis and immunosuppresive treatment may help to slow the accumulation of severe disability.

METHODS: Database records from the National Program for MS were searched for patients with an established diagnosis of MS whose first symptoms appeared before age 18. RESULTS: The national database held records of 1.710 patients; 3.8% had onset of the first symptoms before age 18. 46.7% were boys, yielding an F:M ratio of 1.13:1. Many children had a disease onset characterized by motor impairment (30.7%, brainstem/cerebellum and spinal cord affectation (27.6%, headache (26%. Less frequent symptoms were sensory symptoms (8% and optic neuritis (7%. DISCUSSION: Pediatric MS patients in Venezuela represent a significant proportion of all MS cases. The clinical pattern is characterized by motor symptoms at onset, and predominantly monosymptomatic presentation with a relapsing-remitting pattern. This is the first systematic attempt to estimate the prevalence of pediatric MS in Venezuela.

Despite the recent decline in incidence, it continues to be the deadliest form of skin cancer in children and adolescents. Pediatric melanoma presents differently from adult melanoma; thus, the traditional asymmetry, border irregularity, color variegation, diameter >6 mm, and evolution (ABCDE criteria have been modified to include features unique to pediatric melanoma (amelanotic, bleeding/bump, color uniformity, de novo/any diameter, evolution of mole. Surgical and medical management of pediatric melanoma continues to derive guidelines from adult melanoma treatment. However, more drug trials are being conducted to determine the specific impact of drug combinations on pediatric patients. Alongside medical and surgical treatment, prevention is a central component of battling the incidence, as ultraviolet (UV-related mutations play a central role in the vast majority of pediatric melanoma cases. Aggressive prevention measures targeting sun safety and tanning bed usage have shown positive sun-safety behavior trends, as well as the potential to decrease melanomas that manifest later in life. As research into the field of pediatric melanoma continues to expand, a prevention paradigm needs to continue on a community-wide level. Keywords: melanoma, pediatric, adolescent, childhood

    In 2009, the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) established the Pediatric Terminology Harmonization Initiative to establish a core library of terms to facilitate the acquisition and sharing of knowledge between pediatric clinical research, practice, and safety reporting. A coalition of partners established a Pediatric Terminology Adverse Event Working Group in 2013 to develop a specific terminology relevant to international pediatric adverse event (AE) reporting. Pediatric specialists with backgrounds in clinical care, research, safety reporting, or informatics, supported by biomedical terminology experts from the National Cancer Institute's Enterprise Vocabulary Services participated. The multinational group developed a working definition of AEs and reviewed concepts (terms, synonyms, and definitions) from 16 pediatric clinical domains. The resulting AE terminology contains >1000 pediatric diseases, disorders, or clinical findings. The terms were tested for proof of concept use in 2 different settings: hospital readmissions and the NICU. The advantages of the AE terminology include ease of adoption due to integration with well-established and internationally accepted biomedical terminologies, a uniquely temporal focus on pediatric health and disease from conception through adolescence, and terms that could be used in both well- and underresourced environments. The AE terminology is available for use without restriction through the National Cancer Institute's Enterprise Vocabulary Services and is fully compatible with, and represented in, the Medical Dictionary for Regulatory Activities. The terminology is intended to mature with use, user feedback, and optimization. Copyright © 2017 by the American Academy of Pediatrics.

    In 2006, The Japanese Society of Pediatric Endoscopic Surgeons devised a plan to develop a pediatric endoscopic surgical skill qualification (ESSQ) system. This system is controlled by The Japan Society for Endoscopic Surgery. The standard requirement for skills qualification is the ability of each applicant to complete common types of laparoscopic surgery. The main goal of the system is to decrease complications of laparoscopic surgery by evaluating the surgical skills of each applicant and subsequently certify surgeons with adequate skills to perform laparoscopic operations safely. A committee of pediatric ESSQ created a checklist to assess the applicant's laparoscopic surgical skills. Skills are assessed in a double-blinded fashion by evaluating an unedited video recording of a fundoplication for pediatric gastroesophageal reflux disease. The initial pediatric ESSQ system was started in 2008. In 2008 and 2009, respectively, 9 out of 17 (53%) and 6 out of 12 (50%) applicants were certified as expert pediatric laparoscopic surgeons. Our ultimate goal is to provide safe and appropriate pediatric minimally invasive procedures and to avoid severe complications. To prove the predictive validity of this system, a survey of the outcomes of operations performed by certified pediatric surgeons is required.

  11. Peripheral doses from pediatric IMRT

    International Nuclear Information System (INIS)

    Klein, Eric E.; Maserang, Beth; Wood, Roy; Mansur, David

    2006-01-01

    Peripheral dose (PD) data exist for conventional fields (≥10 cm) and intensity-modulated radiotherapy (IMRT) delivery to standard adult-sized phantoms. Pediatric peripheral dose reports are limited to conventional therapy and are model based. Our goal was to ascertain whether data acquired from full phantom studies and/or pediatric models, with IMRT treatment times, could predict Organ at Risk (OAR) dose for pediatric IMRT. As monitor units (MUs) are greater for IMRT, it is expected IMRT PD will be higher; potentially compounded by decreased patient size (absorption). Baseline slab phantom peripheral dose measurements were conducted for very small field sizes (from 2 to 10 cm). Data were collected at distances ranging from 5 to 72 cm away from the field edges. Collimation was either with the collimating jaws or the multileaf collimator (MLC) oriented either perpendicular or along the peripheral dose measurement plane. For the clinical tests, five patients with intracranial or base of skull lesions were chosen. IMRT and conventional three-dimensional (3D) plans for the same patient/target/dose (180 cGy), were optimized without limitation to the number of fields or wedge use. Six MV, 120-leaf MLC Varian axial beams were used. A phantom mimicking a 3-year-old was configured per Center for Disease Control data. Micro (0.125 cc) and cylindrical (0.6 cc) ionization chambers were appropriated for the thyroid, breast, ovaries, and testes. The PD was recorded by electrometers set to the 10 -10 scale. Each system set was uniquely calibrated. For the slab phantom studies, close peripheral points were found to have a higher dose for low energy and larger field size and when MLC was not deployed. For points more distant from the field edge, the PD was higher for high-energy beams. MLC orientation was found to be inconsequential for the small fields tested. The thyroid dose was lower for IMRT delivery than that predicted for conventional (ratio of IMRT/cnventional ranged from

  12. Pediatric palliative care and pediatric medical ethics: opportunities and challenges.

    Feudtner, Chris; Nathanson, Pamela G

    2014-02-01

    The fields of pediatric palliative care (PPC) and pediatric medical ethics (PME) overlap substantially, owing to a variety of historical, cultural, and social factors. This entwined relationship provides opportunities for leveraging the strong communication skills of both sets of providers, as well as the potential for resource sharing and research collaboration. At the same time, the personal and professional relationships between PPC and PME present challenges, including potential conflict with colleagues, perceived or actual bias toward a palliative care perspective in resolving ethical problems, potential delay or underuse of PME services, and a potential undervaluing of the medical expertise required for PPC consultation. We recommend that these challenges be managed by: (1) clearly defining and communicating clinical roles of PPC and PME staff, (2) developing questions that may prompt PPC and PME teams to request consultation from the other service, (3) developing explicit recusal criteria for PPC providers who also provide PME consultation, (4) ensuring that PPC and PME services remain organizationally distinct, and (5) developing well-defined and broad scopes of practice. Overall, the rich relationship between PPC and PME offers substantial opportunities to better serve patients and families facing difficult decisions.

    2002-01-01

    Background This report describes the utility of hypnosis for patients who presented to a Pediatric Pulmonary Center over a 30 month period. Methods Hypnotherapy was offered to 303 patients from May 1, 1998 – October 31, 2000. Patients offered hypnotherapy included those thought to have pulmonary symptoms due to psychological issues, discomfort due to medications, or fear of procedures. Improvement in symptoms following hypnosis was observed by the pulmonologist for most patients with habit cough and conversion reaction. Improvement of other conditions for which hypnosis was used was gauged based on patients' subjective evaluations. Results Hypnotherapy was associated with improvement in 80% of patients with persistent asthma, chest pain/pressure, habit cough, hyperventilation, shortness of breath, sighing, and vocal cord dysfunction. When improvement was reported, in some cases symptoms resolved immediately after hypnotherapy was first employed. For the others improvement was achieved after hypnosis was used for a few weeks. No patients' symptoms worsened and no new symptoms emerged following hypnotherapy. Conclusions Patients described in this report were unlikely to have achieved rapid improvement in their symptoms without the use of hypnotherapy. Therefore, hypnotherapy can be an important complementary therapy for patients in a pediatric practice. PMID:12460456

    Voluntary active euthanasia for adults at their explicit request has been legal in Belgium and the Netherlands since 2002. In those countries, acceptance of the practice for adults has been followed by acceptance of the practice for children. Opponents of euthanasia see this as a dangerous slippery slope. Proponents argue that euthanasia is sometimes ethically appropriate for minors and that, with proper safeguards, it should be legally available in appropriate circumstances for patients at any age. In this Ethics Rounds, we asked philosophers from the United States and the Netherlands, and a Dutch pediatrician, to discuss the ethics of legalizing euthanasia for children.

    Orthobiologics are biological substances that allow injured muscles, tendons, ligaments, and bone to heal more quickly. They are found naturally in the body; at higher concentrations they can aid in the healing process. These substances include autograft bone, allograft bone, demineralized bone matrix, bone morphogenic proteins, growth factors, stem cells, plasma-rich protein, and ceramic grafts. Their use in sports medicine has exploded in efforts to increase graft incorporation, stimulate healing, and get athletes back to sport with problems including anterior cruciate ligament ruptures, tendon ruptures, cartilage injuries, and fractures. This article reviews orthobiologics and their applications in pediatric sports medicine. Copyright © 2017 Elsevier Inc. All rights reserved.

    2017-11-01

    Program directors (PDs) and trainees are often queried regarding the balance of service and education during pediatric residency training. We aimed to use qualitative methods to learn how pediatric residents and PDs define service and education and to identify activities that exemplify these concepts. Focus groups of pediatric residents and PDs were performed and the data qualitatively analyzed. Thematic analysis revealed 4 themes from focus group data: (1) misalignment of the perceived definition of service; (2) agreement about the definition of education; (3) overlapping perceptions of the value of service to training; and (4) additional suggestions for improved integration of education and service. Pediatric residents hold positive definitions of service and believe that service adds value to their education. Importantly, the discovery of heterogeneous definitions of service between pediatric residents and PDs warrants further investigation and may have ramifications for Accreditation Council for Graduate Medical Education and those responsible for residency curricula.

    The data of the ISAAC project in Spain show a prevalence of childhood asthma ranging from 7.1% to 15.3%, with regional differences; a higher prevalence, 22.6% to 35.8%, is described for rhinitis, and atopic dermatitis is found in 4.1% to 7.6% of children. The prevalence of food allergy is 3%. All children in Spain have the right to be visited in the National Health System. The medical care at the primary level is provided by pediatricians, who have obtained their titles through a 4-yr medical residency training program. The education on pediatric allergy during that period is not compulsory and thus very variable. There are currently 112 certified European pediatric allergists in Spain, who have obtained the accreditation of the European Union of Medical Specialist for proven skills and experience in pediatric allergy. Future specialists in pediatric allergy should obtain their titles through a specific education program to be developed in one of the four accredited training units on pediatric allergy, after obtaining the title on pediatrics. The Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) gathers over 350 pediatric allergists and pediatricians working in this field. SEICAP has a growing activity including yearly congresses, continued education courses, elaboration of technical clinical documents and protocols, education of patients, and collaboration with other scientific societies and associations of patients. The official journal of SEICAP is Allergologia et Immunophatologia, published every 2 months since 1972. The web site of SEICAP, http://www.seicap.es, open since 2004, offers information for professionals and extensive information on pediatric allergic and immunologic disorders for the lay public; the web site is receiving 750 daily visits during 2011.

    Pharmacokinetic parameters from dynamic contrast-enhanced MR imaging have proved useful for differentiating brain tumor grades in adults. In this study, we retrospectively reviewed dynamic contrast-enhanced perfusion data from children with newly diagnosed brain tumors and analyzed the pharmacokinetic parameters correlating with tumor grade. Dynamic contrast-enhanced MR imaging data from 38 patients were analyzed by using commercially available software. Subjects were categorized into 2 groups based on pathologic analyses consisting of low-grade (World Health Organization I and II) and high-grade (World Health Organization III and IV) tumors. Pharmacokinetic parameters were compared between the 2 groups by using linear regression models. For parameters that were statistically distinct between the 2 groups, sensitivity and specificity were also estimated. Eighteen tumors were classified as low-grade, and 20, as high-grade. Transfer constant from the blood plasma into the extracellular extravascular space (K trans ), rate constant from extracellular extravascular space back into blood plasma (K ep ), and extracellular extravascular volume fraction (V e ) were all significantly correlated with tumor grade; high-grade tumors showed higher K trans , higher K ep , and lower V e . Although all 3 parameters had high specificity (range, 82%-100%), K ep had the highest specificity for both grades. Optimal sensitivity was achieved for V e , with a combined sensitivity of 76% (compared with 71% for K trans and K ep ). Pharmacokinetic parameters derived from dynamic contrast-enhanced MR imaging can effectively discriminate low- and high-grade pediatric brain tumors. © 2017 by American Journal of Neuroradiology.

    Immunotherapy for cancer has shown increasing success and there is ample evidence to expect that progress gleaned in immune targeting of adult cancers can be translated to pediatric oncology. This manuscript reviews principles that guide selection of targets for immunotherapy of cancer, emphasizing the similarities and distinctions between oncogene-inhibition targets and immune targets. It follows with a detailed review of molecules expressed by pediatric tumors that are already under study as immune targets or are good candidates for future studies of immune targeting. Distinctions are made between cell surface antigens that can be targeted in an MHC independent manner using antibodies, antibody derivatives, or chimeric antigen receptors versus intracellular antigens which must be targeted with MHC restricted T cell therapies. Among the most advanced immune targets for childhood cancer are CD19 and CD22 on hematologic malignancies, GD2 on solid tumors, and NY-ESO-1 expressed by a majority of synovial sarcomas, but several other molecules reviewed here also have properties which suggest that they too could serve as effective targets for immunotherapy of childhood cancer.

    Pediatric Status Epilepticus (SE) is an emergency situation with high morbidity and mortality that requires early and aggressive management. The minimum time criterion to define SE was reduced from 30 to 5 minutes, defined as continuous seizure activity or rapidly recurrent seizures without resumption of consciousness for more than 5 minutes. This definition considers that seizures that persist for > 5 minutes are likely to do so for more than 30 min. Those that persist for more than 30 minutes are more difficult to treat. Refractory SE is the condition that extends beyond 60-120 minutes and requires anesthetic management. Super-refractory SE is the state of no response to anesthetic management or relapse during withdrawal of these drugs. The aim of this review is to provide and update on convulsive SE concepts, pathophysiology, etiology, available antiepileptic treatment and propose a rational management scheme. A literature search of articles published between January 1993 and January 2013, focused on pediatric population was performed. The evidence about management in children is limited, mostly corresponds to case series of patients grouped by diagnosis, mainly adults. These publications show treatment alternatives such as immunotherapy, ketogenic diet, surgery and hypothermia. A 35% mortality, 26% of neurological sequelae and 35% of recovery to baseline condition is described on patient’s evolution.

    Advances in cardiology, surgical techniques, postoperative care, and medications have improved the chances of long-term survival of the neonatal and pediatric patient with complex congenital cardiac anomalies. Rather than undergoing palliative repair, these children are now frequently taken to the operating room for complete repair. As complete repair becomes the norm, collaborative management and a thorough understanding of the pre and postoperative medications used become essential to the care of these patients. The nurse's ability to understand preop, postop, and management medications is enhanced by an understanding of the principles of cardiac anatomy and physiology, as well as developmental changes in cardiac function. All of these are reviewed. In addition, since the safe and effective administration of these drugs depends on the pediatric intensive care unit (PICU) and neonatal intensive care unit (NICU) nurse's thorough knowledge of these medications and their effects on the cardiovascular system, a brief review of these medications is presented. While new technology and techniques are improving survival rates for children with congenital heart anomalies, it is the postoperative care that these children receive that enhances the patient's survival even more.

    2009-11-01

    Full Text Available Prevalence of pediatric obesity continues to rise worldwide. Increasing the number of health care practitioners as well as pediatricians with expertise in obesity treatment is necessary. Because many obese patients suffer obesity-associated cardiovascular, metabolic and other health complications that could increase the severity of obesity, it is fundamental not only to identify the child prone to obesity as early as possible, but to recognize, treat and monitor obesity-related diseases during adolescence. This short review outlines the treatment of pediatric obesity that may have applications in the primary care setting. It examines current information on eating behavior, sedentary behavior, and details studies of multidisciplinary, behavior-based, obesity treatment programs. We also report the less common and more aggressive forms of treatment, such as medication and bariatric surgery. We emphasize that health care providers have the potential to improve outcomes by performing early identification, helping families create the best possible home environment, and by providing structured guidance to obese children and their families.

    Full Text Available Approach to trichology in the pediatric age group is based on the clinical expertise of the dermatologist and investigative techniques. Currently, the trichoscope is an indispensible, noninvasive tool in the diagnosis of trichological disorders. It not only highlights the subtle tricoscopic points invisible to the naked eye but also serves as a prognostic and monitoring tool in therapeutic management. Trichoscopy goes a long way in improving the diagnostic and clinical acumen of the physician. In the pediatric age group, trichoscopy deals with pattern analysis ranging from hair shaft patterns to follicular, perifollicular, and interfollicular patterns. It not only describes the key trichoscopic features of noncicatricial alopecias, cicatricial alopecias, and genetic hair shaft defects but also helps to delineate various trichological mimics from each other. For compiling data, all trichology cases presenting to a tertiary care center were examined and photographed with a Fotofinder, DermLite Foto II Pro, and DermLite DL 3N. All trichological data were analyzed, and interpretations were based on the literature available.

    Conclusion: The mucous extravasation phenomenon, odontoma, or dentigerous cyst was the most common inflammatory and reactive, neoplastic, or cystic lesion, respectively, in pediatric patients. The relatively high incidence of inflammatory and reactive lesions in pediatric patients implies the importance of stringent oral hygiene in children. Most oral neoplastic lesions in pediatric patients are benign, and malignant oral tumors rarely occur in pediatric patients.

    This review provides a rationale for the use of pharmacotherapy in pediatric weight management, summarizes results of some of the key pediatric clinical trials of approved and "off-label" obesity medications, introduces new options in the pediatric pipeline, and offers a glimpse into the future of pediatric obesity medicine. Despite the need for adjunctive treatments to enhance the outcomes of lifestyle modification therapy among youth with obesity, none of the obesity medications evaluated to date have been shown to meaningfully reduce BMI or cardiometabolic risk factors. Promising medications recently approved for the treatment of obesity in adults will soon be tested in pediatric trials, offering hope that new therapeutic options will soon be available. As new medications are approved to treat pediatric obesity, it will be important to evaluate the safety and efficacy of combination pharmacotherapy and investigate predictors of response. Application of precision medicine approaches to the field of pediatric obesity management will improve the long-term outlook for the tens of millions of youth afflicted with this serious and recalcitrant disease.

    After the geographic and sociodemographic settings as well as the health care in Israel are briefly described, the scope of pediatric allergy and immunology in Israel is presented. This includes specific disorders commonly encountered, the environment that induces symptoms, the specialists who treat them, and the common challenges of patients, parents, doctors, and allied health personnel who collaborate to manage the maladies and patient care. Allergies usually affect some overall 15-20% of the pediatric population. The main allergens are inhaled, ingested, or injected (insects stings). Generally, the incidence of the various allergens affecting children in Israel, is similar to other parts of the Western world. Owing to the high consanguinity rate in the Israeli population, the prevalence of the various immunodeficiency conditions (in the adaptive as well as the innate system) is higher than that reported worldwide. Pediatric allergists/immunologists also treat autoimmune disorders affecting the pediatric group. Pediatric allergy and clinical immunology are not separate specialties. The 25 specialists who treat children with allergic/immunologic diseases have undergone a basic training in Pediatrics. They also received an additional 2-yr training in allergy and clinical immunology and then have to pass the board examinations. They work mainly in pediatric allergy units, in several hospitals that are affiliated to the five medical schools in the country. Aside from clinical work, most of the centers are also heavily involved in clinical and basic research in allergy and immunology. © 2013 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    The University of Pisa was the first in the world to nominate a professor of pediatirics. It was Gaetano Palloni who was nominated professor of ''children diseases'' on April 8(th), 1802 and was assigned to one of the two branch offices of the Pisan University, the one in Florence. He was assigned to ''Ospedale degli Innocenti'' where he taught and also supervised the clinical part. In 1923, he was nominated director of the Gennaro Fiore paediatric clinic and stayed there until 1952 when Augusto Gentili took over. In half a century there were only two professors and this didactic continuity made it possible for Pisa to become one of the greatest Italian pediatric schools.

    Although blood pressure (BP) monitoring is a recommended standard of care by the ASA, and pediatric anesthesiologists routinely monitor the BP of their patients and when appropriate treat deviations from 'normal', there is no robust definition of hypotension in any of the pediatric anesthesia texts or journals. Consequently, what constitutes hypotension in pediatric anesthesia is currently unknown. We designed a questionnaire-based survey of pediatric anesthesiologists to determine the BP ranges and thresholds used to define intraoperative hypotension (IOH). Members of the Society of Pediatric Anesthesia (SPA) and the Association of Paediatric Anaesthetists (APA) of Great Britain and Ireland were contacted through e-mail to participate in this survey. We asked a few demographic questions and five questions about specific definitions of hypotension for different age groups of patients undergoing inguinal herniorraphy, a common pediatric surgical procedure. The overall response rate was 56% (483/860), of which 76% were SPA members. Majority of the respondents (72%) work in academic institutions, while 8.9% work in institutions with fewer than 1000 annual pediatric surgical caseload. About 76% of respondents indicated that a 20-30% reduction in baseline systolic blood pressure (SBP) indicates significant hypotension in children under anesthesia. Most responders (86.7%) indicated that they use mean arterial pressure or SBP (72%) to define IOH. The mean SBP values for hypotension quoted by SPA members was about 5-7% lower across all pediatric age groups compared to values quoted by APA members (P = 0.001 for all age groups). There is great variability in the BP parameters used and the threshold used for defining and treating IOH among pediatric anesthesiologists. The majority of respondents considered a 20-30% reduction from baseline in SBP as indicative of significant hypotension. Lack of a consensus definition for a common clinical condition like IOH could have

    The childhood disorders of glia comprise a group of diseases that include the pediatric leukodystrophies and lysosomal storage disorders, cerebral palsies and perinatal hypoxic ischemic encephalopathies, and selected neurodevelopmental disorders of glial origin. Essentially, all of these disorders...... (GPCs) and their derivatives, the glial disorders may be uniquely attractive targets for cell-based therapeutic strategies, and the pediatric disorders especially so. As a result, GPCs, which can distribute throughout the neuraxis and give rise to new astrocytes and myelinogenic oligodendrocytes, have...... become of great interest as candidates for the therapeutic restoration of normal glial architecture and function, as well as new myelin, to the pediatric brain....

    Full Text Available Burn injuries are a huge public health issue for children throughout the world, with the majority occurring in developing countries. Burn injuries can leave a pediatric patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Rehabilitation is an essential and integral part of pediatric burn treatment. The aim of this article was to review the literature on pediatric burn rehabilitation from the Medline, CINAHL, and Web of Science databases. An attempt has been made to present the basic aspects of burn rehabilitation, provide practical information, and discuss the goals and conceptualization of rehabilitation as well as the development of rehabilitation philosophy and strategies.

    Full Text Available Cushing′s disease (CD, caused by an ACTH-secreting pituitary corticotroph adenoma, is the commonest cause of Cushing syndrome in children over 5 years of age. It is rare in the pediatric age range and presents difficult diagnostic and therapeutic challenges. Key presenting features include weight gain, growth failure and change in facial appearance. Most pediatric endocrinologists have limited experience managing children or adolescents with CD and thus benefit from close consultation with adult colleagues. We describe a diagnostic protocol which broadly follows the model for adult patients. Treatment strategies are examined and appraised. The management of pediatric CD patients after cure is also discussed.

    Accurate cardiovascular imaging is essential for the successful management of patients with congenital heart disease (CHD). Echocardiography and angiography have been for long time the most important imaging modalities in pediatric cardiology, but nuclear medicine has contributed in many situations to the comprehension of physiological consequences of CHD, quantifying pulmonary blood flow symmetry or right-to-left shunting. In recent times, remarkable improvements in imaging equipments, particularly in multidetector computed tomography and magnetic resonance imaging, have led to the progressive integration of high resolution modalities in the clinical workup of children affected by CHD, reducing the role of diagnostic angiography. Technology has seen a parallel evolution in the field of nuclear medicine, with the advent of hybrid machines, as SPECT/CT and PET/CT scanners. Improved detectors, hugely increased computing power, and new reconstruction algorithms allow for a significant reduction of the injected dose, with a parallel relevant decrease in radiation exposure. Nuclear medicine retains its distinctive capability of exploring at the tissue level many functional aspects of CHD in a safe and reproducible way. The lack of invasiveness, the limited need for sedation, the low radiation burden, and the insensitivity to body habitus variations make nuclear medicine an ideal complement of echocardiography. This is particularly true during the follow-up of patients with CHD, whose increasing survival represent a great medical success and a challenge for the health system in the next decades. Metabolic imaging using 18 FDG PET/CT has expanded its role in the management of infection and inflammation in adult patients, particularly in cardiology. The same expansion is observed in pediatric cardiology, with an increasing rate of studies on the use of FDG PET for the evaluation of children with vasculitis, suspected valvular infection or infected prosthetic devices.

    To describe h- and g-indices benchmarks in pediatric subspecialties and general academic pediatrics. Academic productivity is measured increasingly through bibliometrics that derive a statistical enumeration of academic output and impact. The h- and g-indices incorporate the number of publications and citations. Benchmarks for pediatrics have not been reported. Thirty programs were selected randomly from pediatric residency programs accredited by the Accreditation Council for Graduate Medical Education. The h- and g-indices of department chairs were calculated. For general academic pediatrics, pediatric gastroenterology, and pediatric nephrology, a random sample of 30 programs with fellowships were selected. Within each program, an MD faculty member from each academic rank was selected randomly. Google Scholar via Harzing's Publish or Perish was used to calculate the h-index, g-index, and total manuscripts. Only peer-reviewed and English language publications were included. For Chairs, calculations from Google Scholar were compared with Scopus. For all specialties, the mean h- and g-indices significantly increased with academic rank (all P calculation using different bibliographic databases only differed by ±1. Mean h-indices increased with academic rank and were not significantly different across the pediatric specialties. Benchmarks for h- and g-indices in pediatrics are provided and may be one measure of academic productivity and impact. Copyright © 2016 Elsevier Inc. All rights reserved.

  20. Pediatric Obstructive Uropathy: Clinical Trials

    As the powerful tools of molecular biology continue to delineate new concepts of pathogenesis of diseases, new molecular-level therapeutic modalities are certain to emerge. In order to design and execute clinical trials to evaluate outcomes of these new treatment modalities, we will soon need a new supply of investigators with training and experience in clinical research. The slowly-progressive nature of chronic pediatric kidney disease often results in diagnosis being made at a time remote from initial result, and the inherently slow rate of progression makes changes difficult to measure. Thus, development of molecular markers for both diagnosis and rate of progression will be critical to studies of new therapeutic modalities. We will review general aspects of clinical trials and will use current and past studies as examples to illustrate specific points, especially as these apply to chronic kidney disease associated with obstructive uropathy in children.
