ABSTRACT
RESUMEN Introducción: El trastorno por estrés postraumático afectan la salud mental de los pacientes pediátricos, se considera muy común en estos pacientes. Estudios científicos apoyados en la resonancia magnética han fundamentado una estrecha relación entre el estrés postraumático y cambios estructurales en el cerebro. Se realizó una revisión bibliográfica en el periodo de abril a mayo de 2021, en los recursos disponibles en MEDLINE, SciELO, Pubmed y Elsevier. Del total de consultas se citaron 25 referencias. Objetivo: Describir los signos radiológicos en la neuroimagen de pacientes pediátricos con estrés postraumático. Desarrollo: Los estudios de neuroimagen en niños y adolescentes con trastorno por estrés postraumático se han centrado en estructuras anormales y la funcionalidad de algunas regiones individuales del cerebro; estas implican las regiones cerebrales asociadas con la fisiopatología, ellas son: la corteza prefrontal medial y dorsolateral; la corteza orbitofrontal; ínsula; núcleo lentiforme; amígdala; hipocampo y el parahipocampo; la corteza cingulada anterior y posterior; el precúneo; cúneo; el giro fusiforme y lingual y los tractos de materia blanca que conectan estas regiones cerebrales. Conclusiones: Los signos radiológicos en la neuroimagen de pacientes pediátricos con trastorno por estrés postraumático son: reducción de los volúmenes del hipocampo; del volumen cerebral e intracraneal y del volumen de la amígdala, así como una disminución del área total del cuerpo calloso. Además se observa que el volumen hipofisario y los volúmenes de materia gris cerebral fueron menores en los pacientes con estrés postraumático.
ABSTRACT Introduction: Post-traumatic stress disorder affects the mental health of pediatric patients; it is considered very common in these patients. Scientific studies supported by magnetic resonance imaging have established a close relationship between post-traumatic stress and structural changes in the brain. A bibliographic review was carried out in the period from April to May 2021, in the resources available in MEDLINE, SciELO, Pubmed and Elsevier. Of the total of consultations, 25 references were cited. Objective: To describe the radiological signs in the neuroimaging of pediatric patients with post-traumatic stress disorder. Development: Neuroimaging studies in children and adolescents with post-traumatic stress disorder have focused on abnormal structures and the functionality of some individual brain regions; these involve the brain regions associated with pathophysiology, they are: the medial and dorsolateral prefrontal cortex; the orbitofrontal cortex; insula; lentiform nucleus; amygdala; hippocampus and parahippocampus; the anterior and posterior cingulate cortex; the precuneus; cuneus; the fusiform and lingual gyrus and the white matter tracts that connect these brain regions. Conclusions: The radiological signs in the neuroimaging of pediatric patients with post-traumatic stress disorder are: reduction of the volumes of the hippocampus; brain and intracranial volume and amygdala volume, as well as a decrease in the total area of the corpus callosum. In addition, it is observed that the pituitary volume and the volumes of cerebral gray matter were lower in patients with post-traumatic stress.
ABSTRACT
Objective To evaluate the effect of percutaneous transforaminal endoscopic discectomy (PTED) using tar?get puncture and 2-stage procedures in treating lumbar disc hernia. Methods Patients present in our clinic from January 2014 to June 2014 with lumbar disc hernia who were treated with PTED were collected (n=36). Lower back and leg pain were evaluated by visual analog scale (VAS) while clinic outcome were assessed by Oswestry disability index (ODI) and modified Macnab criteria. Results All surgeries were carried out successfully. On average, operation time was(125±31)min, blood loss was(8.5±2.9)mL in each operation. The average length in hospital stay was(7.6±3.5)day. Compared with the preoper?ative VAS scores,the postoperative and last follow-up scores for lower back and leg pain decreased significantly (P<0.01). The ODI of pre-operation and last follow-up were (18.90 ± 7.78)%and (73.30 ± 18.21)%respectively with statistic differ?ence. As to the modified Macnab criteria,theexcellent and goodratio was 94.4%. One case present hyperalgesia in L4 der?matome which recovered through conservative treatment. No complications such as permanent nerve root injury ,cerebrospi?nal fluid leakage,or infection were found during or after operations. All patients are in stable conditions during follow-up pe?riod without recurrence. Conclusion PTED using target puncture and 2-stage procedures is an effective method with mini?mal trauma, less bleeding, quick recovery, high security, short hospitalization time. what′s more, it can remove protruded disc and broken nucleus from the intervertebral space. It ensure efficacy and avoid recurrence.
ABSTRACT
OBJECTIVE: Embitterment is a persistent feeling of being let down or insulted, feeling like a "loser", or feeling revengeful but helpless. In South Korea, social injustice experienced during rapid industrial development and protracted unemployment during the Asian economic crisis may lead to strong feelings of embitterment. North Korean defectors and victims of industrial disasters may also experience humiliation and feelings of injustice. Posttraumatic Embitterment Disorder (PTED) is a recent conceptualization of a new psychiatric disorder. This study tested the reliability and validation of the Korean version of the PTED Scale. METHODS: Subjects aged 18 years or older were recruited from a psychiatric outpatient clinic. All subjects were diagnosed with a depressive disorder. Subjects completed the Korean version of the PTED Scale, the Patient Health Questionnaire (PHQ-9) and the Patient Health Questionnaire (PHQ-15) at baseline and two weeks later. RESULTS: Approximately 15.4% of subjects could be categorized as having PTED. The test-retest reliability of the PTED Scale was good (r=0.76) and the internal consistency was very high (Cronbach's alpha=0.962). Positive correlations were found between the PTED Scale, the PHQ-9 and the PHQ-15, indicating substantial convergent validity of the PTED Scale. CONCLUSION: The Korean version of the PTED Scale is a reliable and valid measurement of embitterment in Korean adults as an emotional reaction to a negative life event.
