Acute treatment of cerebral edema and elevated intracranial pressure is a common issue in patients with neurological injury. Practical recommendations regarding selection and monitoring of therapies for initial management of cerebral edema for optimal efficacy and safety are generally lacking. This guideline evaluates the role of hyperosmolar agents (mannitol, HTS), corticosteroids, and selected non-pharmacologic therapies in the acute treatment of cerebral edema. Clinicians must be able to select appropriate therapies for initial cerebral edema management based on available evidence while balancing efficacy and safety.
The Neurocritical Care Society recruited experts in neurocritical care, nursing, and pharmacy to create a panel in 2017. The group generated 16 clinical questions related to initial management of cerebral edema in various neurological insults using the PICO format. A research librarian executed a comprehensive literature search through July 2018. The panel screened the identified articles for inclusion related to each specific PICO question and abstracted necessary information for pertinent publications. The panel used GRADE methodology to categorize the quality of evidence as high, moderate, low, or very low based on their confidence that the findings of each publication approximate the true effect of the therapy.
The panel generated recommendations regarding initial management of cerebral edema in neurocritical care patients with subarachnoid hemorrhage, traumatic brain injury, acute ischemic stroke, intracerebral hemorrhage, bacterial meningitis, and hepatic encephalopathy.
The available evidence suggests hyperosmolar therapy may be helpful in reducing ICP elevations or cerebral edema in patients with SAH, TBI, AIS, ICH, and HE, although neurological outcomes do not appear to be affected. Corticosteroids appear to be helpful in reducing cerebral edema in patients with bacterial meningitis, but not ICH. Differences in therapeutic response and safety may exist between HTS and mannitol. The use of these agents in these critical clinical situations merits close monitoring for adverse effects. There is a dire need for high-quality research to better inform clinicians of the best options for individualized care of patients with cerebral edema.

Pitt-Hopkins syndrome (PTHS) is a neurodevelopmental disorder characterized by intellectual disability, specific facial features, and marked autonomic nervous system dysfunction, especially with disturbances of regulating respiration and intestinal mobility. It is caused by variants in the transcription factor TCF4. Heterogeneity in the clinical and molecular diagnostic criteria and care practices has prompted a group of international experts to establish guidelines for diagnostics and care. For issues, for which there was limited information available in international literature, we collaborated with national support groups and the participants of a syndrome specific international conference to obtain further information. Here, we discuss the resultant consensus, including the clinical definition of PTHS and a molecular diagnostic pathway. Recommendations for managing particular health problems such as dysregulated respiration are provided. We emphasize the need for integration of care for physical and behavioral issues. The recommendations as presented here will need to be evaluated for improvements to allow for continued optimization of diagnostics and care.

This revision to the EEG Guidelines is an update incorporating the current electroencephalography technology and practice. It was previously published as Guideline 2. Similar to the prior guideline, it delineates the aspects of Guideline 1 that should be modified for neonates and young children. Recording conditions for photic stimulation and hyperventilation are revised to enhance the provocation of epileptiform discharges. Revisions recognize the difficulties involved in performing an EEG under sedation in young children. Recommended neonatal EEG montages are displayed for the reduced set of electrodes only since the montages in Guideline 3 should be used for a 21-electrode 10-20 system array. Neonatal documentation is updated to use current American Academy of Pediatrics term \"postmenstrual age\" rather than \"conceptional age.\" Finally, because therapeutic hypothermia alters the prognostic value of neonatal EEG, the necessity of documenting the patient\'s temperature at the time of recording is emphasized.

Traumatic brain injury (TBI) exacts a great toll on society. Fortunately, there is growing evidence that the management of TBI in the early minutes after injury may significantly reduce morbidity and mortality. In response, evidence-based prehospital and in-hospital TBI treatment guidelines have been established by authoritative bodies. However, no large studies have yet evaluated the effectiveness of implementing these guidelines in the prehospital setting. This article describes the background, design, implementation, emergency medical services (EMS) treatment protocols, and statistical analysis of a prospective, controlled (before/after), statewide study designed to evaluate the effect of implementing the EMS TBI guidelines-the Excellence in Prehospital Injury Care (EPIC) study (NIH/NINDS R01NS071049, \"EPIC\"; and 3R01NS071049-S1, \"EPIC4Kids\"). The specific aim of the study is to test the hypothesis that statewide implementation of the international adult and pediatric EMS TBI guidelines will significantly reduce mortality and improve nonmortality outcomes in patients with moderate or severe TBI. Furthermore, it will specifically evaluate the effect of guideline implementation on outcomes in the subgroup of patients who are intubated in the field. Over the course of the entire study (~9 years), it is estimated that approximately 25,000 patients will be enrolled.

BACKGROUND: Severe TBIs are major causes of disability and death in accidents. The Brain Trauma Foundation supported the first edition of the Guidelines for the Management of Severe Traumatic Brain Injury in 1995 and revised it in 2000. The recommendations in these guidelines are well accepted in the world. There are still some different views on trauma mechanisms, pathogenesis, and managements in different areas. Individualized guidelines for different countries would be necessary, and Taiwan is no exception.
METHODS: In November 2005, we organized the severe TBI guidelines committee and selected 9 topics, including ER treatment, ICP monitoring, CPP, fluid therapy, use of sedatives, nutrition, intracranial hypertension, seizure prophylaxis, and second-tier therapy. We have since searched key questions in these topics on Medline. References are classified into 8 levels of evidence: 1++, 1+, 1-, 2++, 2+, 2-, 3, and 4 based on the criteria of the SIGN.
RESULTS: Recommendations are formed and graded as A, B, C, and D. Grade A means that at least one piece of evidence is rated as 1++, whereas grade B means inclusion of studies rated as 2++. Grade C means inclusion of references rated as 2+, and grade D means levels of evidence rated as 3 or 4. Overall, 42 recommendations are formed. Three of these are rated as grade A, 13 as grade B, 21 as grade C, and 5 as grade D.
CONCLUSIONS: We have completed the first evidence-based, clinical practice guidelines for severe TBIs. It is hoped that the guidelines will provide concepts and recommendations to promote the quality of care for severe TBIs in Taiwan.

BACKGROUND: Breath tests represent a valid and non-invasive diagnostic tool in many gastroenterological conditions. The rationale of hydrogen-breath tests is based on the concept that part of the gas produced by colonic bacterial fermentation diffuses into the blood and is excreted by breath, where it can be quantified easily. There are many differences in the methodology, and the tests are increasingly popular.
OBJECTIVE: The Rome Consensus Conference was convened to offer recommendations for clinical practice about the indications and methods of H2-breath testing in gastrointestinal diseases.
METHODS: Experts were selected on the basis of a proven knowledge/expertise in H2-breath testing and divided into Working Groups (methodology; sugar malabsorption; small intestine bacterial overgrowth; oro-coecal transit time and other gas-related syndromes). They performed a systematic review of the literature, and then formulated statements on the basis of the scientific evidence, which were debated and voted by a multidisciplinary Jury. Recommendations were then modified on the basis of the decisions of the Jury by the members of the Expert Group.
CONCLUSIONS: The final statements, graded according to the level of evidence and strength of recommendation, are presented in this document; they identify the indications for the use of H2-breath testing in the clinical practice and methods to be used for performing the tests.

The Commission of European Affairs of the International League Against Epilepsy published \'Appropriate Standards for Epilepsy Care Across Europe\' which contained recommendations for the use of electroencephalography (EEG) in the diagnosis of epilepsy (Brodie et al. Epilepsia 1997; 38:1245). The need for a more specific basic document of EEG methodology was recognized and the Subcommission on European Affairs was asked to produce more detailed guidelines to be used across Europe recognizing the range of practices in EEG laboratories. There are many general guidelines published on EEG methodology but this document focuses on the diagnosis of epilepsy. Details from previously published guidelines are included in references and in an appendix. These guidelines are not meant to be used as minimal standards but recommendations that can be applied to all EEG laboratories despite variations in equipment.

BACKGROUND: This study assessed patients with traumatic brain injury (TBI) to determine whether prehospital and community hospital providers employed hyperventilation therapy inconsistent with consensus recommendation against its routine use.
METHODS: This prospective analysis of 37 intubated TBI patients without herniation, undergoing helicopter transport to an urban Level I center, entailed flight crews\' noting of assisted ventilation rate (AVR) and end-tidal carbon dioxide (ETCO2) upon their arrival at trauma scenes or community hospitals. A priori-set levels of AVR and ETCO2 were used to assess frequency of guideline-inconsistent hyperventilation, and Fisher\'s exact and Kruskal-Wallis tests assessed association between guideline-inconsistent hyperventilation and manual vs. mechanical ventilation mode.
RESULTS: Inappropriately high AVR and low ETCO2 were seen in 60% and 70% of patients, respectively. Manual ventilation was associated with guideline-inconsistent hyperventilation assessed by AVR (p = 0.038) and ETCO2 (p = 0.022).
CONCLUSIONS: Prehospital and community hospital hyperventilation practices are not consistent with consensus recommendations for limitation of hyperventilation therapy.
