Age as a prognostic factor in relation to surgical evacuation of spontaneous supratentorial intracerebral haemorrhage

Aim and clinical rationale for the study: Spontaneous intracerebral haemorrhage (sICH) is an acute life-threatening injury and constitutes 10–15% of first-ever stroke cases. The Surgical Trials in Intracerebral Haematoma studies (STICH and STICH II) represent the two foremost studies in the field, however, with arguable shortcomings. To find more accurate criteria, we aimed to correlate the preoperative neurological and neuroimaging findings with the clinical outcome of operated patients. Materials and methods: In this retrospective study, sICH patients were recruited from the Central Denmark Region from 2010 to 2016. We evaluated the patients' medical records regarding preoperative Glasgow Coma Scale (GCS) 6 months and one year after surgery, focal neurological defects, thrombolytic treatment, pupil status, and haemorrhage localization visualized by neuroimaging. The patients' clinical outcome was assessed using the Glasgow Outcome Scale (GOS). Results: Based on logistic multiple linear analysis, age, basal ganglia haemorrhage and mass effect had significant effect on the mortality rate. Besides, age, basal ganglia haemorrhage, intra ventricular haemorrhage and pupil difference had significant correlation with goodoutcome (GOS > 3).Conclusions and clinical implications: Neurosurgical treatment of the sICH patients is indicated only if age and potentially improved morbidity is carefully evaluated considering the STICH and this study; otherwise, we will just increase the health care burden with a number of extremely care-dependent patients

A review of blood transfusions in a trauma unit for young children

Background. Trauma is the leading cause of mortality and morbidity worldwide. Blood transfusions play an incremental role in the acute phase, yet practice varies owing to variations in transfusion thresholds and concerns about potential complications, especially in children.Objectives. To evaluate protocol adherence to blood transfusion thresholds in paediatric trauma patients and determine the degree of blood product wastage, as defined by discarded units.Methods. A retrospective, descriptive study of trauma patients (age 0 - 13 years) who received a blood transfusion in the trauma unit at Red Cross War Memorial Children’s Hospital, Cape Town, South Africa, over a 5.5-year period (1 January 2009 - 1 July 2014). Haemoglobin (Hb) transfusion thresholds were defined as 10 g/dL for neurotrauma patients and patients requiring skin grafting or a musculocutaneous flap (group 1). All other trauma patients had an Hb transfusion threshold of 7 g/dL (group 2).Results. A total of 144 patients were included (mean age 5.2 years (standard deviation (SD) 3.3), 68.1% male). The mean Hb increase after transfusion was 3.5 g/dL (SD 1.7). Adherence to the transfusion Hb threshold protocol was 96.7% for group 1 v. 34.0% for group 2. No complications were reported. Average blood wastage was 3.5 units per year during the study period.Conclusions. Adherence to paediatric blood transfusion protocol was low in the Hb threshold group <7 g/dL. However, transfusion-related complications and wastage were minimal. Further prospective research is required to determine optimal blood transfusion guidelines for paediatric trauma patients

Analgosedation in paediatric severe traumatic brain injury (TBI): practice, pitfalls and possibilities

Analgosedation is a fundamental part of traumatic brain injury (TBI) treatment guidelines, encompassing both first and second tier supportive strategies. Worldwide analgosedation practices continue to be heterogeneous due to the low level of evidence in treatment guidelines (level III) and the choice of analgosedative drugs is made by the treating clinician. Current practice is thus empirical and may result in unfavourable (often hemodynamic) side effects. This article presents an overview of current analgosedation practices in the paediatric intensive care unit (PICU) and addresses pitfalls both in the short and long term. We discuss innovative (pre-)clinical research that can provide the framework for initiatives to improve our pharmacological understanding of analgesic and sedative drugs used in paediatric severe TBI and ultimately facilitate steps towards evidence-based and precision pharmacotherapy in this vulnerable patient group

Beware of thermal epiglottis! A case report describing 'teapot syndrome'

Background: The type of scalding injury known as 'teapot syndrome', where hot liquid is grabbed by the child with the aim of ingestion and falls over a child causing burns on the face, upper thorax and arms, is known to cause peri-oral and facial oedema. Thermal epiglottitis following scalds to face, neck and thorax is rare and can occur even in absence of ingestion of a damaging agent or intraoral burns, Awareness of the possibility of thermal epiglottitis, also in scald burns, is imperative to ensure prompt airway protection. Case presentation: We report the case of a child with thermal epiglottitis after a scalding burn from boiling milk resulting in mixed deep burns of the face, neck and chest, but no history of ingestion. Upon presentation there was a progressive stridor and signs of respiratory distress requiring intubation. Laryngoscopy revealed epiglottis oedema, confirming the diagnosis of thermal epiglottitis. Final extubation took place 5 days after initial burn. Conclusions: Thermal epiglottitis following scalds to face, neck and thorax is rare and can occur even in absence of ingestion and intra-oral damage. Burns to the peri-oral area should raise suspicion of additional damage to oral cavity and supraglottic structures, even in absence of intra-oral injury or initial respiratory distress. Awareness of the occurrence of thermal epiglottitis in absence of intra-oral injury is important to diagnose impending upper airway obstruction requiring intubation

Hyperoxia in pediatric severe traumatic brain injury (TBI): a comparison of patient classification by cutoff versus cumulative (area-under-the-curve) analysis

Objective: Hyperoxia is associated with adverse outcome in severe traumatic brain injury (TBI). This study explored differences in patient classification of oxygen exposure by PaO2 cutoff and cumulative areaunder-the-curve (AUC) analysis. Methods: Retrospective, explorative study including children (<18 years) with accidental severe TBI (2002–2015). Oxygen exposure analysis used three PaO2 cutoff values and four PaO2 AUC categories during the first 24 hours of Pediatric Intensive Care Unit (PICU) admission. Results: Seventy-one patients were included (median age 8.9 years [IQR 4.6–12.9]), mortality 18.3% (n = 13). Patient hyperoxia classification differed depending on PaO2 cutoff vs AUC analysis: 52% vs. 26%, respectively, were classified in the highest hyperoxia category. Eleven patients (17%) classified as ‘intermediate oxygen exposure’ based on cumulative PaO2 analysis whereby they did not exceed the 200 mmHg PaO2 cutoff threshold. Patient classification variability was reflected by Pearson correlation coefficient of 0.40 (p-value 0.001). Conclusions: Hyperoxia classification in pediatric severe TBI during the first 24 hours of PICU admission differed depending on PaO2 cutoff or cumulative AUC analysis. We consider PaO2 cumulative (AUC) better approximates (patho-)physiological circumstances due to its time- and dose-dependent approach. Prospective studies exploring the association between cumulative PaO2, physiological parameters (e.g. ICP, PbtO2) and outcome are warranted as different patient classifications of oxygen exposure influences how its relationship to outcome is interpreted

The contribution of rat studies to contemporary knowledge of Major Depressive Disorder: Results from citation analysis

Open access publication costs were covered by Animalfree Research-Switzerland and by funding provided by the Ketty and Leif Hjordt Foundation.Major depressive disorder (MDD) is the most severe depression type and one of the leading causes of morbidity worldwide. Animal models are widely used to understand MDD etiology, pathogenesis, and treatment, but the efficacy of this research for patients has barely been systematically evaluated. Such evaluation is important given the resource consumption and ethical concerns incurred by animal use. We used the citation tracking facilities within Web of Science and Scopus to locate citations of original research papers on rats related to MDD published prior to 2013—to allow adequate time for citations—identified in PubMed and Scopus by relevant search terms. Resulting citations were thematically coded in eight categories, and descriptive statistics were calculated. 178 publications describing relevant rat studies were identified. They were cited 8,712 times. More than half (4,633) of their citations were by other animal studies. 794 (less than 10%) were by human medical papers. Citation analysis indicates that rat model research has contributed very little to the contemporary clinical understanding of MDD. This suggests a misuse of limited funding hence supporting a change in allocation of research and development funds targeting this disorder to maximise benefits for patients.Publisher PDFPeer reviewe

Social cognition and idiopathic isolated cervical dystonia

For a long time, cervical dystonia (CD) has been characterised only by disturbances in motor functioning. Despite accumulating evidence for symptomatology in various non-motor domains, to date no study has investigated social cognition in CD. The aim of this study was to compare performance of CD patients and healthy controls in neurocognitive and socio-cognitive domain. Twenty-five non-depressed patients with CD and 26 healthy controls underwent neuropsychological testing. This involved assessment of cognitive status (general intellect, verbal memory, and executive function), and socio-cognitive functions using a Theory of mind task and self-report on empathy and emotion regulation. In comparison to controls, CD patients displayed significantly decreased cognitive abilities, particularly in executive function and verbal memory tasks. Difficulties in inferring mental states on both cognitive and affective levels were also observed. The largest discrepancies were detected in understanding intentionality in others. Poorer performance in cognitive and socio-cognitive tasks was unrelated to severity of the disease. This is the first evidence of compromised socio-cognitive functions in CD patients, highlighting this domain as another facet of non-motor symptoms of this disease. Future studies should advance our understanding of the extent, nature, and time course of these deficits in other aspects of social cognition in this patient population
