RESUMEN
INTRODUCTION: Decreasing unnecessary cranial computed tomography (CT) use in pediatric head trauma patients remains important for emergency departments (EDs) across the US. Our study evaluated CT use in children with minor blunt head trauma in 21 community EDs within an integrated health-care system. METHODS: We studied all children younger than 18 years old presenting to 21 community EDs between 2016 through 2018 with acute minor blunt head trauma, defined by an algorithm of ED chief complaints and diagnoses. We excluded patients with traumatic brain injuries diagnosed in the prior year, a CT within 24 hours prior to the ED visit, or an ED Glasgow Coma Scale score of less than 14. RESULTS: Among 39,792 pediatric minor head trauma ED visits, the aggregate CT use proportion across all EDs was 12.9% [95% confidence interval (CI), 12.6-13.3%; facility-level range, 5.4-21.6%]. The 7 facilities that had previously received a clinical decision support system intervention implementing the Pediatric Emergency Care Applied Research Network rules during 2013 through 2014 had an aggregate mean CT ordering rate of 11.2% (95% CI, 10.7-11.7%; facility-level range, 5.4-14.3%) compared to 14.1% (95% CI, 13.6-14.5%; facility-level range, 7.3-21.6%) for the nonintervention facilities. CONCLUSION: CT use for children with minor blunt head trauma in the community EDs of an integrated health-care system was low and stable across facilities from 2016 through 2018. This may be indicative of the safe stewardship of resources in the system, including the absence of financial or medicolegal incentives to scan very low-risk patients as well the availability of resources for close patient follow-up.

Water polo is a unique team sport combining swimming sprints and eggbeater kicking, frequent overhead movements and throwing, and regular physical contact with minimal protective equipment. Accordingly, a wide variety of training methods attempt to enhance all of these skill sets. This usually includes some combination of aerobic/anaerobic fitness (via swimming), sport-specific skills, strengthening, and nutrition. In addition, injuries in water polo are somewhat diverse. Physical contact is responsible for the majority of acute injuries, most frequently being injuries to the head and face. The high prevalence of shoulder pain in water polo is likely related to increased shoulder mobility and subsequent instability and stress on shoulder structures, yet the underlying causation is not certain. The unique aspect of shoulder injuries occurring in water polo players is that they may be due to a combination of swimming-related overuse conditions, overhead throwing, and acute trauma-related conditions. Although there is generally minimal evidence-based information available, this article attempts to highlight the current knowledge that we have in regard to water polo injuries and training methods.

Traumatic brain injury commonly has a result of a short window of opportunity between the period of initial brain injury and secondary brain injury, which provides protective strategies and can reduce damages of brain due to secondary brain injury. Previous studies have reported neuroprotective effects of extremely low-frequency electromagnetic fields. However, the effects of extremely low-frequency electromagnetic fields on neural damage after traumatic brain injury have not been reported yet. The present study aims to investigate effects of extremely low-frequency electromagnetic fields on neuroprotection after traumatic brain injury. Male Sprague-Dawley rats were used for the model of lateral fluid percussion injury, which were placed in non-electromagnetic fields and 15 Hz (Hertz) electromagnetic fields with intensities of 1 G (Gauss), 3 G and 5 G. At various time points (ranging from 0.5 to 30 h) after lateral fluid percussion injury, rats were treated with kainic acid (administered by intraperitoneal injection) to induce apoptosis in hippocampal cells. The results were as follows: (1) the expression of hypoxia-inducible factor-1α was dramatically decreased during the neuroprotective time window. (2) The kainic acid-induced apoptosis in the hippocampus was significantly decreased in rats exposed to electromagnetic fields. (3) Electromagnetic fields exposure shortened the escape time in water maze test. (4) Electromagnetic fields exposure accelerated the recovery of the blood-brain barrier after brain injury. These findings revealed that extremely low-frequency electromagnetic fields significantly prolong the window of opportunity for brain protection and enhance the intensity of neuroprotection after traumatic brain injury.

The problem of cardiovascular disease and cancer, the effects of traumatic brain injury is now one of the major health and social problems. Every year in Ukraine registered 200 thousand cases of the victims of traumatic brain injury. Of these, 30% of people then have persistent signs of disability that results in a disability, sometimes painful existence the patient and his relatives. Therefore, in order to bring man back into society after a traumatic brain injury, to the rehabilitation phase of treatment, immediately after the stabilization of the patient.

BACKGROUND: Mild traumatic brain injury (mTBI) is being claimed as the 'signature' injury of the Iraq war, and is believed to be the cause of long-term symptomatic ill health (post-concussional syndrome; PCS) in an unknown proportion of military personnel. METHOD: We analysed cross-sectional data from a large, randomly selected cohort of UK military personnel deployed to Iraq (n=5869). Two markers of PCS were generated: 'PCS symptoms' (indicating the presence of mTBI-related symptoms: none, 1-2, 3+) and 'PCS symptom severity' (indicating the presence of mTBI-related symptoms at either a moderate or severe level of severity: none, 1-2, 3+). RESULTS: PCS symptoms and PCS symptom severity were associated with self-reported exposure to blast whilst in a combat zone. However, the same symptoms were also associated with other in-theatre exposures such as potential exposure to depleted uranium and aiding the wounded. Strong associations were apparent between having PCS symptoms and other health outcomes, in particular being a post-traumatic stress disorder or General Health Questionnaire case. CONCLUSIONS: PCS symptoms are common and some are related to exposures such as blast injury. However, this association is not specific, and the same symptom complex is also related to numerous other risk factors and exposures. Post-deployment screening for PCS and/or mTBI in the absence of contemporaneous recording of exposure is likely to be fraught with hazards.

Meditation has been a spiritual and healing tradition for centuries. In 1972, Keith Wallace and Herbert Benson published a landmark article looking at meditation from a scientific perspective. The author reviewed their article, plus selected scientific literature on meditation since that time, to see if there was enough evidence to warrant the inclusion of meditation in the treatment protocols of serious disease. This review, plus an illustrative case study, demonstrated that such inclusion is warranted and further research is necessary.

Previous research has shown that complex statistical analysis (discriminant function analysis) of a 'normal' auditory brainstem response (ABR) result can improve this measure's ability to predict subject outcome following severe acute closed head injury (ACHI). We hypothesized that adding the ABR's time-frequency information to such an analysis would improve this predictive value even further. 'Normal' ABR results were sampled from 69 severe ACHI subjects (22 of whom died and 47 of whom lived) and their time-frequency information extracted using an over-complete discrete wavelet transformation (OCDWT). A series of logistic regression analyses then showed correct predictions of death and survival as follows: ABR measures only 72 and 89% (respectively), ABR OCDWT measures only 82 and 89% (respectively), and ABR and ABR OCDWT measures combined 86 and 93% (respectively). These results showed that the addition of time-frequency information can improve the ability of the 'normal' ABR result to predict outcome following severe ACHI.

Memory impairment following closed-head injury (CHI) in children is well documented. Characterization of the memory deficits of children with CHI could contribute to the prediction of academic performance and rehabilitation of these children. Twenty-five children who sustained closed-head injury and 25 matched controls were administered the Rey Auditory Verbal Learning Test (AVLT). The advantage of this memory test is that a number of memory components are measured simultaneously, thus enabling us to study the relations between different aspects of memory within the same patient sample. The findings indicate that the Rey AVLT is a good test for characterization of impaired verbal memory in children following CHI. Transformation of scores derived from the Rey AVLT to Z-scores enables us to determine the relative effect of CHI in children on different memory scores. Raw scores were more vulnerable than relational ones, derived as the difference between two raw scores (e.g., learning, Trial 5 - 1), to closed-head injury in children, and scores reflecting word span were the least vulnerable. The results are discussed in terms of the possible contribution of the frontal lobes, which are frequently affected in closed-head injuries, to memory performance.

The Gulf War syndrome represents neurological and neuropsychological disorders in veterans of the Persian Gulf war. Until today, the various symptoms observed could not be attributed to any defined disease. As a possible cause, exposure to neurotoxic agents such as the organophosphates used during the war has been suggested by many authors. We report on a 29-year-old man who suffered from dysmnesia, disturbance of orientation, cognitive impairment, and double vision. His history revealed several front-line operations in 1990 and 1991 during the Gulf War. Physical examinations showed a complex eye-movement disturbance and a horizontal nystagmus, which was neuro-ophthalmologically confirmed. The early auditory potentials referred to a brainstem dysfunction and the cognitive disturbances correlated to changes in the late-appearing component of event-related potentials (P 300). Brain imaging with CCT, MRI, SPECT, PET, and EEG and CSF showed no pathologies. Neuropsychological tests disclosed severe cognitive impairment especially concerning memory. Three-month follow-up studies in a department of psychosomatic medicine excluded a dissociative disorder as a feature of a post-traumatic stress or a conversion disorder. This is the first case of Gulf War syndrome in Germany. We focus on an unfamiliar complication after the war. The recent literature is reviewed.

Over 50% of individuals who suffer traumatic brain injury (TBI) demonstrate a decrease in sexual arousal post-injury. This study investigated the basis of this loss and hypothesized that it occurred as a consequence of the effect of the injury on cognition: specifically, diminution of the ability to form and manipulate sexually arousing imagery. The study compared 14 male participants who identified themselves as having alteration in sexual functioning following traumatic brain injury with a further 14 non-brain injured participants, case matched to them for age and education. All TBI participants were assessed after 2 years following injury, and had had a loss of consciousness of 3 days or greater. The results indicated that the two groups differed in terms of their performance on the Bett's QMI Scale, the Gordon Test of Visual Imagery Control, the Vividness of Sexual Imagery Scale of the Imaginal Processes Inventory, the State Trait Anxiety Inventory, and the Beck Depression Inventory. After correction for the level of depression by analysis of covariance, the TBI participants still featured lower levels of performance on the Sexual Imagery sub-scale of the Imaginary Processes Inventory. The results indicate that sexual arousal disturbances may exist above and beyond the disturbances to affect associated with the psychosocial effects of the TBI.

Disciplines such as sociology and anthropology have showed that the experience of illness, is above all, a social product, that is, that social factors of different kinds play a central role in shaping individuals' subjectivity. This paper refers to the case of Ocuituco, a rural town of central Mexico. The article presents some of the results achieved through an interpretive sociological study of individuals' subjective experience of traditional illnesses such as susto, soul-loss, and fallen fontanelle. The aim is to analyze how Ocuituco's inhabitants attach meaning to, interpret, and experience these illnesses. The main point being made is that the subjective experience of traditional illnesses is shaped both by the cultural background of individuals, and by the sociological features of the setting where these individuals live. Data are interpreted in connection both to structural factors (poverty, medicalization, and patriarchy), and to the main traits that characterize individuals' view of their world: a sense of uncertainty, a sense of the unexpected as being normal, a sense of being oppressed, a familiarity with a patriarchal order. It is shown that both susto and fallen fontanelle are belief systems which allow individuals to interpret their circumstances and attach meaning to their problematic everyday life.

Dystonia rarely is a consequence of head trauma. In most of these patients lesions of the contralateral caudate or putamen are found. We report a 27-year-old patient who displayed focal dystonia of the right hand with the latency of four months after he had sustained a severe head trauma. The development of a lesion in the contralateral dorsolateral thalamus within the first weeks after the craniocerebral injury is demonstrated with sequential computertomographic and magnetic resonance imaging. There were no lesions of the caudate or the putamen.

Clinical features of thalamic strokes have not been well delineated in children. Six children with ischemic thalamic infarcts (3 M, 3 F; age range: 21 months to 14 1/2 years) are reported. Three patients had infarction in the thalamoperforate artery territory and all had a decreased level of consciousness and hemiparesis; two of them also had associated ocular motility abnormalities. One patient with left thalamotuberal artery stroke presented with aphasia. Two patients with thalamogeniculate artery infarcts had hemiparesis and involvement of the posterior cerebral artery. Etiologic factors in our patients were: infectious vasculitis, congenital heart disease, migraine, and unknown in 1 patient each and trauma in 2 patients. Follow-up information was available for 5, 4 of whom recovered completely. One patient was left with a neurologic deficit. We conclude that the prognosis of ischemic thalamic strokes in children is relatively good.
