Factores asociados al desarrollo de secuelas por trauma craneoencefálico en menores de 15 años: un estudio de cohorte retrospectiva en un hospital de Medellín, Colombia. 2010-2014

Introducción: el trauma craneoencefálico es una de las principales causas de morbimortalidad infantil en Colombia, sus secuelas impactan gravemente la calidad de vida de los pacientes y la evidencia científica actual de los factores asociados al trauma es escasa. Objetivo: analizar los factores asociados al desarrollo de secuelas por trauma craneoencefálico en menores de 15 años que consultaron a un hospital de Medellín entre 2010 y 2014. Materiales y métodos: estudio de cohorte retrospectivo. Se incluyeron 812 pacientes en un periodo de 5 años, de los cuales 294 no cumplieron los criterios de inclusión. Se evaluaron variables sociodemográficas, clínicas y se estimó la incidencia de secuelas con el método estadístico de Wilson. El riesgo relativo se calculó mediante regresión log-binomial. Resultados: en total se analizaron 518 pacientes. La mediana de edad fue de 5 años, el 64,3 % eran hombres, el 75,4 % de los participantes tenía un trauma leve y el 5 % un trauma grave. Las caídas fueron la principal causa (64,2 %), seguidas de los accidentes de tránsito (25,3 %). La incidencia de secuelas fue del 7.3 % (IC: 5,4 % - 9,9 %). Conclusiones: la carga de enfermedad en el paciente posterior a TCE representa un problema de salud pública. La probabilidad de desarrollar una secuela en este estudio fue del 7,3 %, la cual se relaciona con los siguientes factores que se identifican en el servicio de urgencias: lesión difusa, una escala de Glasgow al ingreso moderada o grave y sufrir un accidente de tránsito.

Background: traumatic brain injury is one of the main causes of infant morbidity and mortality. The sequelae after trauma seriously impact the quality of life of patients and the scientific evidence of associated factors is scarce. Objective: to analyze the factors associated with the development of sequelae due to head trauma in children under 15 years old who went to the emergency room of a hospital in Medellín between 2010 and 2014. Materials and methods: retrospective cohort study. 812 patients were included in a period of 5 years, of which 294 did not meet the inclusion criteria. Sociodemographic and clinical variables were evaluated and the incidence of sequelae was estimated with 95 % confidence intervals using the Wilson statistical method. The relative risk was calculated using log-binomial regression. Results: a total of 518 patients were analyzed. The median age was 5 years, 64,23 % were male children, 75,4 % had mild trauma, and 5 % suffered severe trauma. Falls were the main cause (64,2 %), followed by traffic accidents (25,3 %). The incidence of sequelae was 7,3 % (CI: 5,4% - 9,9 %). Conclusions: the burden of disease in the patient after TCE represents a public health problem. The probability of developing a sequel in this study was 7,3 %, which is related to the following factors that identify in the emergency department: diffuse injury, a moderate or severe Glasgow scale on admission, and suffering a traffic accident.

Estimulação cerebral por pulsos sonoros de baixa frequência como coadjuvante nas alterações das funções corticais superiores / Non-invasive brain stimulation by low-frequency sound pulses as an adjunct to changes in higher cortical functions

Não há dúvidas sobre os prejuízos na vida humana, extensivos à família e sociedade como um todo, abrangendo todos os aspectos funcionais das pessoas envolvidas, além do indivíduo, originados dos traumatismos cranioencefálico, agudos e crônicos, externos ou internos: acidentes, atropelamentos, quedas, crimes, acidente vascular cerebral, doenças com neurodegeneração progressiva, resultando em estados demenciais. Ao longo de meio século, houve a introdução contínua de medicamentos, com resultados usualmente contraditórios e frustrantes, exigindo novas tentativas com outras classes farmacológicas. No todo, a limitação se faz sentir na impossibilidade de reversão ou mesmo de mera estabilização dos danos neurológicos, e inocuidade em termos de estimulação da neuroplasticidade. Uma exceção parece ser uma nova abordagem: a estimulação cerebral profunda por pulsos sonoros de baixa frequência (Transcranial Pulse Stimulation, ou TPS). Ainda pouco conhecida, a não ser em alguns centros de tratamento, tem se mostrado ser um acréscimo válido, por complementar os programas multidisciplinares de reabilitação

There is no doubt about the damage to human life, also extended to family and society as a whole, regarding all the functional aspects of those involved, not only the patient itself, which originates from traumatic brain injury, acute or chronic, for external or internal reasons, such as accidents, run overs, falls, crimes, stroke, progressive neurodegenerative diseases that result in dementia states. Over half a century, drugs have been continuously introduced, however their results have constantly been contradictory and frustrating, requiring new attempts with other pharmacological classes. Overall, the limitation is felt in the impossibility of reversing or even merely stabilizing the neurological damage and inefficacy regarding neuroplasticity stimulation. One exception seems to be a new approach, the non-invasive brain stimulation by low-frequency sound pulses (Transcranial Pulse Stimulation, or TPS). Except for some treatment centers, TPS is still unknown, however it has shown to be a valid adjunct in multidisciplinary rehabilitation programs

The efficacy of neuroendoscope-assisted drainage with lumbar cistern and large bone flap decompression in the treatment of craniocerebral trauma complicated with temporal uncinate herniation / 中国医师进修杂志

Objective:To observe the effect of neuroendoscope-assisted drainage with lumbar cistern and large bone flap decompression in the treatment of craniocerebral injury complicated with temporal uncinate herniation.Methods:A total of 80 patients with craniocerebral trauma and temporal uncinate herniation hospitalized in Lanling County People′s Hospital from January 2017 to October 2020 were retrospectively included and divided into the observation group and the control group according to the surgical methods, with 40 patients in each group. Surgical procedures were performed by the same group of experienced neurosurgeons. The observation group was treated with neuroendoscope-assisted drainage with lumbar cistern and large bone flap decompression, while the control group was treated with large bone flap decompression only. Cephalic CT was reexamined before and 48 h after the surgery to compare the appearance rates of cisterna ambiens and suprasellar cistern. Intracranial pressure (ICP) was monitored at 3, 5 and 7 d after the surgery, and the scores of Glasgow coma scale(GCS) was recorded. Drainage time, postoperative cerebral edema and cerebral infarction complications were recorded and compared between the two groups. Six months after the surgery, the prognosis was assessed by the Glasgow prognostic scale (GPS).Results:The occurrence rates of cisterna ambiens and suprasellarcistern in the observation group were higher than those in the control group: 67.50%(27/40) vs. 45.00%(18/40), 65.00%(26/40) vs. 42.50%(17/40), χ2 = 4.11, 4.07, P<0.05. The ICP value in the observation group at 3, 5 and 7 d after the surgery were significantly lower than those in the control group, and the scores of GCS in the observation group were significantly higher than those in the control group, there were statistical differences( P<0.05). There was no statistically significant difference in drainage time between the two groups ( P>0.05). The incidence of postoperative cerebral edema in the observation group was lower than that in the control group:7.50%(3/40) vs. 25.00%(10/40), χ2 = 4.50, P<0.05. The incidence of postoperative cerebral infarction in the observation group was lower than that in the control group, and the volume of cerebral infarction was smaller than that in the control group: 5.00%(2/40) vs. 22.50%(9/40), (6.68 ± 1.75) cm 3 vs. (8.20 ± 2.15) cm 3, there were statistical differences ( P<0.05). The incidence of postoperative complications in the observation group was lower than that in the control group: 7.50%(7/40) vs. 40.00%(16/40), χ2 = 4.94, P<0.05. Six months after the surgery, the rate of good prognosis in the observation group was higher than that in the control group: 62.50%(25/40) vs. 35.00%(14/40), χ2 = 6.05, P<0.05. Conclusions:Neuroendoscope-assisted drainage with lumbar cistern and large bone flap decompression in the treatment of craniocerebral trauma and temporal uncinate herniation has good efficacy and safety.

Analysis of injury factors and of traumatic brain injury in children / 中国实用护理杂志

Objective:To analyze the injury factors and prognosis of children with traumatic brain injury (TBI), and to explore the risk factors affecting its severity, so as to provide evidence for the prevention and intervention of TBI in children.Methods:A total of 6 040 children with TBI who were admitted to the Department of Neurosurgery of Children's Hospital of Soochow University from January 1, 2011 to December 31, 2020 were selected. The injury factors and prognosis were retrospectively analyzed. Univariate and multivariate Logistic regression analysis was used to analyze the factors affecting the severity of TBI in children.Results:Of the 6 040 children, 3 681 were males and 2 359 were females. The patients aged 1 to 3 years accounted for the highest proportion (34.0%, 2 056/6 040), and most of them were mild injuries (93.2%, 5 631/6 040). The main injury sites of children with TBI were road (35.9%, 2 167/6 040) and home (31.1%, 1 881/6 040), and the main causes of injury were falling from height (34.9%, 2 107/6 040) and falling (34.5%, 2 085/6 040). Children aged 1 to 3 years were most likely to be injured at home(41.9%, 861/2 056), mainly due to falling from height, while children aged 4 to 6 years were most likely to be injured on the road(43.8%, 828/1 891), mainly due to falling. Logistic regression analysis showed that children's residence, the presence of multiple injuries and the location of brain injury were independent influencing factors for the severity of TBI in children ( χ2=6.58, 138.15, 4.25, all P <0.05). Conclusions:TBI in children aged 1 to 3 years mainly occurred at home, and in children aged 4 to 6 years mainly occurred on the road. Falling from height and falling are the main causes of TBI in children. The society, schools and families should take targeted prevention education and intervention measures according to different age groups. Children who live in rural areas, have multiple injuries, and have multiple brain injury sites are more severely injured. In the process of treating children with TBI, the severity can be quickly predicted based on this, and the treatment efficiency of children with TBI can be improved.

Relationship between serum sodium level and prognosis of severe craniocerebral injury / 国际外科学杂志

Objective:To explore the effect of different blood sodium levels on the condition and prognosis of patients with severe craniocerebral injury.Methods:A retrospective cohort study was conducted on 150 cases of severe craniocerebral injury admitted to Zhangye People′s Hospital Affiliated to Hexi University from January 2020 to October 2022. According to the five blood sodium values measured on the first day after admission and during the peak period of brain edema (2-4 days after injury) and 7 days after injury, 102 cases of blood sodium metabolic disorder, 43 cases of low sodium group: average blood sodium value<135 mmol/L, 59 cases of high sodium group: average blood sodium value>145 mmol/L. The characteristics of sodium ion metabolism imbalance and the relationship between serum sodium level and Glasgow coma score (GCS), Glasgow prognosis score (GOS) and APACHE Ⅱ score at 2 weeks after injury were analyzed. Measurement data with normal distribution were represented as mean±standard deviation ( ± s), and comparison between groups was conducted using the t-test. count data were expressed as cases or percentages(%), and comparison between groups was conducted using the Chi-square test. Results:The imbalance rate of sodium metabolism in the acute phase after injury was 68.00%(102/150), including 57.84%(59/102) of hypernatremia and 42.16%(43/102) of hyponatremia. The imbalance rate of sodium metabolism at 7 days after injury was significantly higher than that immediately after injury. Hypernatremia occurred earlier than hyponatremia and lasted longer than hyponatremia ( P<0.05). There was no correlation between the low sodium group and the scores of GCS ( R=0.523), GOS ( R=0.367), APACHE Ⅱ ( R=-0.453) ( P>0.05), but the scores of GCS ( R=-0.448) and GOS ( R=-0.486) were negatively correlated with the blood sodium level of the high sodium group ( P<0.05), and the high sodium group was positively correlated with the scores of APACHE Ⅱ ( R=0.477, P<0.05). Conclusions:Patients with severe craniocerebral injury are often accompanied by blood sodium disorder. Hyponatremia can be corrected in a short time and has no effect on the patient′s condition and prognosis. However, hypernatremia seriously affects the recovery of consciousness, prognosis and quality of life of the injured.

Research progress in characteristics and field surgical treatment of craniocerebral war injury in foreign armies / 中华创伤杂志

Craniocerebral war injury, mainly caused by weaponry equipment and wartime conditions during warfare, are characterized by high difficulty in treatment and evacuation as well as high mortality rate. The field surgical treatment of craniocerebral war injury is not only related to injury characteristics, but also to factors such as war scale, combat style, combat area and weapon power. In recent years, there have been few comprehensive reports on the characteristics and field surgical treatment of craniocerebral war injury in China. Therefore, the authors reviewed the research progress in the characteristics and field surgical treatment of craniocerebral war injuries in foreign armies since 2001, with the aim to provide a reference for relevant basic researches and war injury treatment in China.

Certain issues for medical evacuation and support after traumatic brain injury at high altitude / 中华创伤杂志

Traumatic brain injury (TBI) is much more complex considering the unique pathophysiological changes under high-altitude hypoxic environment. Moreover, because of limited source of medical transportation and facilities at high altitude, TBI patients often lack urgent and standard treatment and have to be transported to the district medical center at high altitude or even the neurotrauma center at plain region as soon as possible. The transportation has high risk and takes serious effect on lives and prognosis of the TBI patients. Up to date, the evacuation and support process for TBI patients in the western plateau region of China has been improved through years of practice, but there are still deficiencies compared to the Critical Care Air Transport Team (CCATT). The authors sought to discuss certain issues related to medical evacuation and support after TBI at high altitude from aspects of early damage control operation and timely safety medical transportation, aiming to improve the survival rate, neurological outcomes and life quality for these patients.

Research progress in the pathogenesis, diagnosis and treatment for posttraumatic acute diffuse brain swelling / 中华创伤杂志

Posttraumatic acute diffuse brain swelling (PADBS) is a relatively common severe traumatic brain injury (TBI). Since it can lead to acute intracranial hypertension in a short time, the illness can be acute and critical, with a high disability and fatality rate. The pathogenesis of PADBS is still unclear, with the current theory consisting of acute cerebral vasodilation, cerebral edema and intracranial venous circulation disorder. For PADBS, there is still a lack of unified diagnostic criteria, and the indications and timing of decompression craniectomy remain controversial. The authors review the research progress in the pathogenesis, diagnosis and treatment of PADBS, hoping to provide some new ideas for its treatment.

Application value of ventricular intracranial pressure monitoring in the treatment of unilateral temporal lobe cerebral contusion / 中华创伤杂志

Objective:To explore the application value of ventricular intracranial pressure monitoring (V-ICPM) in the treatment of unilateral temporal lobe cerebral contusion.Methods:A retrospective cohort study was conducted to analyze the clinical data of 295 patients with unilateral temporal lobe cerebral contusion admitted to 904th Hospital of PLA Joint Support Force from January 2014 to August 2021, including 172 males and 123 females; aged 14-78 years [(46.3±14.7)years]. V-ICPM was used in 136 patients (V-ICPM group), who received surgical or non-surgical treatment according to the monitoring, while not in 159 patients (non-V-ICPM group), who received routine surgery or non-surgical treatment. The two groups were compared in terms of the rates of intracranial hematoma clearance by craniotomy, decompressive craniectomy (DC) and dehydration and osmotic therapy during hospitalization, use time of 20% mass fraction of mannitol and 30 g/L hypertonic salt, displacement rate of brain midline structure of head CT≥10 mm after discharge, rate of intracranial infection, hydrocephalus and epilepsy, and Glasgow Outcome Scale (GOS) at 6 months after discharge.Results:All patients were followed up for 6-12 months [(8.9±2.1)months]. During hospitalization, the rate of intracranial hematoma clearance by craniotomy and the rate of DC in V-ICPM group were 35.3% (48/136) and 8.1% (11/136), lower than 47.2% (75/159) and 22.0% (35/159) in non-V-ICPM group ( P<0.05 or 0.01). There was no significant difference between the two groups in the rate of dehydration and osmotic therapy or the use time of mannitol (all P>0.05). The use time of hypertonic salt in V-ICPM group was (7.2±2.5)days, more than (4.1±1.8)days in non-V-ICPM group ( P<0.05). After discharge, the displacement rate of brain midline structure of head CT in V-ICPM group was 29.4% (40/136), lower than 42.8% (68/159) in non-V-ICPM group ( P<0.05). There was no significant difference between the two groups in the rate of intracranial infection, hydrocephalus and epilepsy (all P>0.05). Six months after discharge, the good rate of GOS in V-ICPM group was 91.2% (124/136), significantly better than 81.8% (130/159) in non-V-ICPM group ( P<0.05). Conclusion:For unilateral temporal lobe cerebral contusion, V-ICPM is associated with reduced rate of craniotomy exploration and DC, decreased incidence of complications and improved prognosis of the patients in spite of longer use time of hypertonic salt.

Evaluation of pediatric patients presenting with acute-onset unilateral transient acquired blepharoptosis / Avaliação de pacientes pediátricos apresentando blefaroptose transitória unilateral de início agudo

ABSTRACT Purpose: To evaluate the clinical features of pediatric patients with acute-onset, unilateral transient acquired blepharoptosis. Methods: In this retrospective study, the clinical records of patients between April 2015 and June 2020 were reviewed for evaluation of demographic features, accompanying neurological and ophthalmologic manifestations, symptom duration, etiological cause, and imaging findings. Patients with congenital and acquired blepharoptosis with chronic etiologies were excluded. Results: Sixteen pediatric patients (10 boys and 6 girls) with acquired acute-onset unilateral transient blepharoptosis were included in this study. The patients' mean age was 6.93 ± 3.16 years. The most commonly identified etiological cause was trauma in 7 patients (43.75%) and infection (para-infection) in 5 patients (31.25%). In addition, Miller Fisher syndrome, Horner syndrome secondary to neuroblastoma, acquired Brown's syndrome, and pseudotumor cerebri were identified as etiological causes in one patient each. Additional ocular findings accompanied blepharoptosis in 7 patients (58.33%). Blepharoptosis spontaneously resolved, without treatment, in all the patients, except those with Miller Fisher syndrome, neuroblastoma, and pseudotumor cerebri. None of the patients required surgical treatment and had ocular morbidities such as amblyopia. Conclusion: This study demonstrated that acute-onset unilateral transient blepharoptosis, which is rare in childhood, may regress without the need for surgical treatment in the pediatric population. However, serious pathologies that require treatment may present with blepharoptosis.

RESUMO Objetivo: Avaliar as características clínicas de pacientes pediátricos com blefaroptose adquirida unilateral, transitória e de início agudo. Métodos: Neste estudo retrospectivo, foram revisados prontuários clínicos entre abril de 2015 e junho de 2020. Os pacientes foram avaliados em termos de características demográficas, manifestações neurológicas e oftalmológicas associadas, duração dos sintomas, etiologia e achados de imagem. Foram excluídos pacientes com blefaroptose congênita e com blefaroptose adquirida de etiologia crônica. Resultados: Foram incluídos neste estudo 16 pacientes pediátricos (10 masculinos e 6 femininos) com blefaroptose adquirida transitória unilateral de início agudo. A média de idade dos pacientes foi de 6,93 ± 3,16 anos. As causas etiológicas mais comumente identificadas foram trauma em 7 pacientes (43,75%) e infecção (casos parainfecciosos) em 5 pacientes (31,25%). Além disso, a síndrome de Miller-Fisher, a síndrome de Horner secundária a neuroblastoma, a síndrome de Brown adquirida e pseudotumor cerebral foram determinados como causas etiológicas em um paciente cada uma. Achados oculares adicionais estavam associados à blefaroptose em 7 pacientes (58,33%). Foi observada a resolução espontânea da blefaroptose, sem tratamento, em todos os pacientes, exceto nos pacientes com síndrome de Miller-Fisher, neuroblastoma e pseudotumor cerebral. Nenhum paciente precisou de tratamento cirúrgico. Morbidades oculares, como ambliopia, não foram encontradas em nenhum paciente. Conclusão: Este estudo demonstrou que a blefaroptose transitória unilateral de início agudo, rara na infância, pode regredir sem a necessidade de tratamento cirúrgico na população pediátrica. No entanto, também não deve ser esquecido que patologias graves que requerem tratamento podem se apresentar com blefaroptose.

A study on application of deep learning reconstruction in low-dose brain CT in children with craniocerebral trauma / 中华放射学杂志

Objective:To explore the application value of deep learning reconstruction (DLR) in low-dose brain CT imaging in children with craniocerebral trauma.Methods:The CT data of 51 children with craniocerebral trauma complicated with intracerebral hemorrhage who received low dose brain CT were retrospectively collected in Hunan Children′s Hospital between June 2020 and February 2021. All images were reconstructed at 1.25 mm and 5 mm slice thickness utilizing two reconstruction algorithms and divided into six subgroups: ASIR-V with three different blending ratios (0, 50%, 100%), and DLR with three different reconstruction strengths [low (L), media (M) and high (H)]. The objective parameters including CT value, signal to noise ratio (SNR) and contrast to noise ratio (CNR) of dorsal thalamus (grey matter), white matter of frontal lobe and hemorrhagic lesion, as well as basicranial artifact noise (SD) and background SD were measured and calculated. Subjective evaluation was performed with a 5-point scale scoring. Objective parameters and subjective scores were compared among different groups using randomized block analysis of variance and Friedman test, respectively. The objective and subjective differences between 1.25 mm DLR-H and ASIR-V50% images were analyzed using paired samples t-test and correlated sample rank sum test. Results:The average CT dose index volume, dose length product and size-specific dose estimate of head CT were 17.7 (11.9, 21.1) mGy, 248.4 (142.2, 338.1) mGy·cm and (15.7±2.8) mGy. With the same thickness, the difference of CT values between the DLR and ASIR-V groups were stastistically significant ( P<0.05). The subjective scores of DLR groups were significantly better than those of ASIR-V; the higher was the reconstruction grade of ASIR-V and DLR, the higher SNR and CNR values and the lower SD value were obtained for each structure (all P<0.05). DLR images showed better objective parameters than ASIR-V50% images. Background:SD was lowest on DLR-H and ASIR-V100% images, with no significant difference found between these two groups. Using 1.25 mm thickness, DLR-H images showed higher SNR (for both gray matter and white matter) and CNR than ASIR-V100% images ( P<0.05). The subjective score was decreased with the slice thickness reduced. However, the average subjective scores of 1.25 mm DLR images were all over 3 points, while those of 1.25 mm ASIR-V images were less than 3 points, which could not fully meet the needs of diagnosis. Images of 1.25 mm DLR-H had higher background SD and artifact SD than 5 mm ASIR-V50% images ( t=2.96, 2.83, P=0.005, 0.007), while the score and other objective parameters were not statistically different between these two groups ( P>0.05). Conclusion:In children′s low-dose cerebral CT, DLR can improve image quality, with the DLR-H images displaying the highest image quality. It can also increase the SNR and CNR of gray and white matter of images with thin thickness.

Characteristics, diagnosis and treatment of craniocerebral firearm trauma at high altitude / 中华创伤杂志

The high-altitude craniocerebral firearm trauma can induce severe injuries with poor prognosis. Compared with the plain area, the bullets show faster velocity, longer shooting range, and greater kinetic energy due to the low pressure, low oxygen, cold, and dry climate at high altitude, resulting in more serious cerebral tissue damage and higher mortality. At present, there are few studies over craniocerebral firearm trauma at high altitude. Therefore, the authors discuss craniocerebral firearm trauma at high altitude from aspects of epidemiological and pathological characteristics, diagnosis, and treatment in combination with the situation in plain area, so as to provide a reference for the basic research and clinical treatment of craniocerebral firearm trauam at high altitude.

Clinical analysis of 37 patients with bilateral frontal lobe contusion / 中国基层医药

Objective:To investigate the treatment methods and their efficacy for bilateral frontal lobe contusion.Methods:The clinical data of 37 patients with bilateral frontal lobe contusion who received treatment in Fujian Provincial Hospital between May 2017 and May 2018 were analyzed. The 37 patients were divided into surgical group ( n = 19) and non-surgical group ( n = 18) according to different treatment methods. Clinical efficacy was compared between the two groups. All patients underwent intracranial pressure monitoring. Intracerebral pressure was divided into three stages: < 20 mmHg, 20-40 mmHg, > 40 mmHg. Clinical efficacy was compared among patients with different levels of intracranial pressure. Results:In the surgical group, one patient died, one patient was in a vegetative state, two patients had severe disability, eight patients had mild disability, and seven patients well recovered. In the non-surgical group, four patients died, three patients were in a vegetative state, six patients had severe disability, three patients had mild disability, and two patients well recovered. There was significant difference in good recovery rate between the two groups ( χ2 = 9.83, P < 0.05). The good recovery rate was statistically significant among patients with different levels of intracranial pressure ( χ2 = 7.97, P < 0.05). The vegetative state rate in patients with > 40 mmHg intracranial pressure was significantly higher than that in patients with < 20 mmHg intracranial pressure (50.0% vs. 0.0%, χ2 = 7.65, P < 0.05). The good recovery rate in patients with > 40 mmHg intracranial pressure was significantly lower than that in patients with < 20 mmHg intracranial pressure (0.0% vs. 61.5%, χ2 = 7.57, P < 0.05). Conclusion:The choice of treatment for bilateral frontal lobe contusion mainly depends on clinical symptoms, dynamic brain CT findings, and the changes in dynamic intracranial pressure monitoring. Active surgery can reduce the incidence of death and severe disability. Intracranial pressure monitoring has a positive role in guiding clinical treatment.

Analysis of risk factors of acute gastrointestinal failure in patients with traumatic brain injury / 中国医师进修杂志

Objective:To investigate the risk factors of acute gastrointestinal failure in patients with traumatic brain injury(TBI).Methods:A retrospective analysis of 297 patients admitted to the Rugao Hospital Affiliated to Nantong University for traumatic brain injury from March 2018 to March 2020 was performed. Multivariate Logistic regression analysis was used to test the risk factors of acute gastrointestinal failure in patients with traumatic brain injury.Results:Of the 297 patients with TBI, 92 (30.98%) had acute gastrointestinal failure, of which 56 (18.86%) were acute gastrointestinal injury(AGI) Ⅲ and 36 (12.12%) were AGI Ⅳ. Multivariate Logistic regression analysis showed that female, low Glasgow Coma Scale (GCS) scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection were independent risk factors for acute gastrointestinal failure in TBI patients ( P<0.05). The length of ICU stay in the acute gastrointestinal failure group was significantly higher than that of the non-acute gastrointestinal failure group: (18.5 ± 2.6) d vs. (6.3 ± 1.2) d, and the incidence of good prognosis was significantly lower than that of the non-acute gastrointestinal failure group: 60.87%(56/92) vs. 80.49(165/205), the differences were statistically significant ( P<0.05). Conclusions:That female, low GCS scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection are independent risk factors for acute gastrointestinal failure in TBI patients

Clinical assessment of head injuries in motorcyclists involved in traffic accidents: A prospective, observational study / Investigação da presença de lesões traumáticas em segmento cefálico em motociclistas vítimas de acidentes de tráfego: Estudo observacional prospectivo

ABSTRACT Objective: to review the clinical assessment of head injuries in motorcyclists involved in traffic accidents. Method: prospective observational study, including adult motorcyclists involved in traffic accidents in a period of 12 months. Patients sustaining signs of intoxication were excluded. A modification of the Canadian Head CT Rules was used to indicate computed tomography (CT). Patients not undergoing CT were followed by phone calls for three months. Collected variables were compared between the group sustaining head injuries and the others. We used chi-square, Fisher, and Student's t for statistical analysis, considering p<0.05 as significant. Results: we included 208 patients, 99.0% were wearing helmets. Seventeen sustained signs of intoxication and were excluded. Ninety (47.1%) underwent CT and 12 (6.3%) sustained head injuries. Head injuries were significantly associated with Glasgow Coma Scale<15 (52.3% vs. 2.8% - p<0,001) and a positive physical exam (17.1% vs. zero - p<0,05). Four (2.1%) patients with intracranial mass lesions needed surgical interventions. None helmet-wearing patients admitted with GCS=15 and normal physical examination sustained head injuries. Conclusion: Head CT is not necessary for helmet-wearing motorcyclists admitted with GCS=15 and normal physical examination.

RESUMO Objetivo: análise crítica da investigação diagnóstica de lesões em segmento cefálico de motociclistas vítimas de acidentes de tráfego. Método: estudo observacional prospectivo incluindo motociclistas adultos vítimas de trauma, sem intoxicação exógena, em um período de 12 meses. A tomografia de crânio (TC) foi indicada de acordo com uma modificação dos "critérios canadenses". Os pacientes que não foram submetidos a TC de crânio tiveram acompanhamento telefônico por três meses. A presença de lesões foi correlacionada com as varáveis coletadas através dos testes Qui-quadrado, t de Student ou Fisher, considerando p<0,05 como significativo. Resultados: dos 208 inicialmente incluídos, 206 (99,0%) estavam usando capacete. Dezessete estavam com sinais de intoxicação exógena e foram excluídos, restando 191 para análise. Noventa pacientes (47,1%) realizaram TC e 12 (6,3%) apresentaram lesões craniencefálicas, que se associaram significativamente a Escala de Coma de Glasgow (ECG) <15 (52,3% vs. 2,8% - p<0,001) e alterações ao exame físico da região cefálica/neurológico (17,1% vs. zero - p<0,05). Quatro pacientes (2,1%) precisaram tratamento cirúrgico de lesões intracranianas. Nenhum dos pacientes admitidos com ECG 15, em uso de capacete e sem alterações no exame físico apresentou TC alterada. Conclusões: para pacientes admitidos com ECG 15, que utilizavam o capacete no acidente e não apresentavam quaisquer alterações no exame físico, a realização da TC de crânio não trouxe mudanças no atendimento ao paciente. .

One case of Mycoplasma hominis-related intracranial infection after craniocerebral injury / 中华检验医学杂志

The patient, a 50-year-old male, was admitted to the hospital on April 1, 2020 with the chief complaint of "confusion with vomiting for 1 hour due to falling from height ", and the emergency craniotomy was performed. Intermittent fever with a maximum temperature of 38 ℃ occurred 3 days after the surgery, and the inflammation indexes were all higher than the upper limit of the reference values. Recurrent fever remained despite after empirical anti-infection treatment. On April 12, the patient was treated with vancomycin combined with meropenem after cerebrospinal fluid specimens routine and biochemical tests suggested intracranial infection. After 48 hours of cultivating the cerebrospinal fluid and blood specimens, some small, clear, needle-like colonies were found and they were identified as Mycoplasma humanum by using 16S rRNA gene. Eventually, the patient died due to the severity of the disease and complications.

Weighted correlation network analysis of gene expression profiling data after traumatic brain injury / 中华创伤杂志

Objective:To screen important genes and characterize their functions and signaling pathways by weighted gene co-expression network analysis (WGCNA) on the gene expression profile of brain tissue after traumatic brain injury (TBI) so as to provide a reference for the mechanism research and treatment of TBI.Methods:The rat TBI gene expression profile GSE2871 was downloaded from the Gene Expression Omnibus (GEO). The expression profile of 8 799 genes of all 47 rat brain tissue samples was analyzed by WGCNA. After calculating and selecting the β-weighted soft threshold, undirected weighted gene network was constructed to identify gene sets with a high degree of correlation. Sample information was obtained from the database to calculate the correlation between each trait of the samples and modules. Gene ontology (GO) analysis and KEGG pathway analysis were performed for the genes in modules related to injury severity and sampling side in order to unvail the biological processes and pathways involved. The gene-module correlation and gene-trait correlation in these key modules were calculated and hub genes were selected.Results:All the rat brain tissue samples and genes in GSE2871 were included in the WGCNA analysis. A total of 22 modules were obtained, which were marked as modules A to V. Modules E, G, T and U were significantly associated with the sampling side. Modules E and G were significantly related to injury severity . GO analysis and KEGG pathway analysis indicated that the genes in modules E and G with significant relation to injury severity and sampling side were mainly implicated in leukocyte migration, cell chemotaxis, various immune response regulation, etc. The involved pathways included antigen processing and presentation pathways, cell factor-cytokine receptor interaction, interleukin-17 signaling pathway, etc. While modules T and U with significant relation to the sampling side were mainly implicated in hypoxia response, cell metabolism, cell membrane ion channel regulation, signal transduction, etc. The pathways involved were neurodegenerative disease signaling pathways, ribosomes, autophagy, neuroactive ligand-receptor interactions, etc. Among the key modules significantly relating to traits, Tuba1b/1c, Ifitm3, Cebpd, Nfkbia, Serinc3, Pmpcb and Cyp4a8 were selected as hub genes of the above key modules.Conclusion:The genes significantly relating to rat TBI are mainly involved in pathophysiological links such as immune activation, inflammatory response, abnormal energy metabolism, calcium channel disorders, abnormal autophagy and cell apoptosis.
