Árnica es una planta medicinal de la especie Arnica montana, endémica en Europa Central y Meridional, perteneciente a la familia Asteracae; rica en flavonoides y compuestos fenólicos, lactonas, helenalina y ácido hexurónico que le dan propiedades cicatrizantes, antiinflamatorias, analgésicas, antimicrobianas y anticoagulantes. Se utiliza en casos de contusiones, dolores musculares, reumáticos y hematomas profundos. El artículo describe ocho casos, que presentaron hematoma profundo por punción infructuosa, en pacientes con insuficiencia renal crónica terminal con esquema de hemodiálisis, donde se aplicó árnica en gel. Por medio de fotografías se registró cómo los hematomas revirtieron a partir del tercer día, mientras que el dolor disminuyó en un 50% al tercer día. (AU)

Arnica is a medicinal plant of the species Arnica Montana, endemic in Central and Southern Europe, it belongs to the Asteracae family, rich in flavonoids and phenolic compounds, lactones, helenalin and hexuronic acid that give it healing, anti-inflammatory, analgesic, antimicrobial and anticoagulant properties. It is used in cases of bruises, muscle pain, rheumatic pain and deep bruises. The article describes eight patients with terminal chronic renal failure under hemodialysis, who presented deep hematoma due to unsuccessful puncture of their dialysis fistula. All patients were treated with local gel arnica. Verbal analogue scale (VAS) and qualitative visual image analysis (photography) on how the hematomas reverted on the third day was analyzed. (AU)

Hematoma orbitario secundario a cirugía endoscópica nasosinusal / Orbital hematoma secondary to endoscopic sinus surgery

Resumen Durante la cirugía endoscópica nasosinusal, la sección inadvertida y retracción hacia la órbita de la arteria etmoidal anterior (AEA) es el mecanismo habitual del hematoma orbitario (HO); éste se manifiesta con proptosis, dolor y déficit visual potencialmente irreversible. El déficit visual es secundario a isquemia del nervio óptico por aumento de la presión intraocular, siendo suficientes treinta minutos para que ocurra daño visual permanente. Por sus secuelas el tratamiento del HO debe ser rápido y agresivo. Presentamos el caso de un varón de 72 años con diagnóstico de rinosinusitis crónica con pólipos nasales refractaria a tratamiento médico que se sometió a cirugía endoscópica nasal y que desarrolló en el posoperatorio inmediato con un HO. Se manejó precozmente con cantotomía-cantolisis, descompresión orbitaria medial endoscópica y control vascular de la AEA. El paciente evoluciona favorablemente, sin déficit visual. En este artículo se discutirán el diagnóstico y manejo oportunos del hematoma orbitario iatrogénico.

Abstract During endoscopic sinonasal surgery, inadvertent section of the anterior ethmoidal artery (AEA) with retraction into the orbit is the usual mechanism of orbital hematoma (OH), leading to proptosis, pain, and potentially irreversible visual loss. Thirty minutes is sufficient for retinal ischemia and permanent visual loss. The explanation for blindness is due to increased intraorbital pressure. The treatment of iatrogenic HO must be quick and aggressive, because if it is not managed in time, it can cause a permanent visual deficit. We present the case of a 72-year-old man with a diagnosis of chronic rhinosinusitis with nasal polyps refractory to medical treatment who underwent nasal endoscopic surgery, evolving in the immediate postoperative period with an HO, requiring canthotomy - cantolysis and early surgical reintervention for endoscopic medial orbital decompression and vascular control of AEA. The patient evolves favorably, without visual deficit. This article will discuss the timely diagnosis and management of iatrogenic orbital hematoma.

Hematoma retropúbico masivo posterior a TVT: enfrentamientos diferentes para una complicación infrecuente / Massive retropubic hematoma after TVT: different approaches for an uncommon complication

INTRODUCCIÓN: La TVT (tension-free vaginal tape) es una cirugía efectiva, pero no exenta de riesgos. Las complicaciones vasculares ocurren en un 0,9-1,7%; solo el 0,33% se presentan como hematoma masivo, en general asociado a la lesión de variante anatómica corona mortis (CM). OBJETIVO: Reportar tres tipos de manejo en pacientes con hematomas masivos después de cirugía para la incontinencia. MÉTODO: Revisión de casos de hematomas masivos tras TVT. Análisis de tres casos con diferente manejo. RESULTADOS: 1086 pacientes operadas en 10 años, 1% hematomas sintomáticos, 0,36% hematomas masivos. Se presentan tres casos. Caso 1: presenta inestabilidad hemodinámica sin respuesta a volumen ni vasoactivos, requirió laparotomía exploradora y se encontró un vaso sangrante retropúbico, compatible con CM, y un hematoma de 1000 cc. Caso 2: hipotensión que responde a volumen, asintomática al día siguiente de alta, reingresó 12 días después con caída de 6 puntos en la hemoglobina y la tomografía computarizada (TC) mostró un hematoma de 550 cc; recibió drenaje percutáneo. Caso 3: asintomática, alta el primer día posoperatorio, reingresa al quinto día con descenso de 4 puntos en la hemoglobina y la TC informa hematoma de 420 cc, que drena espontáneamente por vía vaginal. Todas las pacientes recibieron 14 días de antibióticos, y permanecieron continentes. CONCLUSIONES: Los hematomas retropúbicos masivos son una complicación poco frecuente. Su manejo considera la estabilización hemodinámica, el control del sangrado y el drenaje.

INTRODUCTION: TVT (tension-free vaginal tape) is an effective surgery, not without risks. Vascular complications occur in 0.9 to 1.7%, of which 0.33% present as massive hematoma, generally associated with injury of an anatomical variant, Corona Mortis (CM). OBJECTIVE: To report three types of management in patients with massive hematomas after anti-incontinence surgery. METHOD: Review of cases of massive hematomas after TVT surgery. Analysis of three cases with different management. RESULTS: 1086 patients operated in 10 years, 1% symptomatic hematomas, 0.36% massive. Three cases are presented. Case 1: hemodynamic instability without response to volume or vasoactive agents, required reoperation with exploratory laparotomy, a retropubic bleeding vessel, compatible with CM, and hematoma 1000 cc was found. Case 2: hypotension responds to volume, asymptomatic at next day in discharge conditions, she was readmitted 12 days later with falled 6-point in Hb, and CT showed hematoma 550 cc; she received percutaneous drainage. Case 3: asymptomatic, discharge on the first day after TVT, readmitted on the 5th day with falled 4-point in Hb, CT informed hematoma 420 cc, spontaneously drains vaginally. Patients received 14 days of antibiotics, remained continent. CONCLUSIONS: Massive retropubic hematomas are an infrequent complication, and management considers hemodynamic stabilization, bleeding control and drainage.

Surgical Repair of a Ruptured Giant Abdominal Aortic Aneurysm in a 16-Year-Old with Takayasu's Arteritis: Case Report and Etiological Review

Abstract Takayasu's arteritis is a type of primary systemic vasculitis that affects medium and large arteries, including the aorta and its main branches, as well as the pulmonary and coronary arteries. Although rare in children, it is the third most common vasculitis in the pediatric population, often with delayed diagnosis due to the nonspecific presentation of clinical symptoms in its initial phase. This is a case of a 16-year-old girl with a giant ruptured abdominal aortic aneurysm, who needed surgery on an emergency basis. The etiological aspects involved in aneurysms in young patients are also addressed.

Application and clinical efficacy of ultrasound debridement method in residual burn wounds / 中华烧伤杂志

Objective: To investigate the application and clinical efficacy of ultrasound debridement method in residual burn wounds. Methods: A retrospective cohort study was conducted. From August 2017 to August 2021, 64 patients with residual burn wounds who met the inclusion criteria were admitted to the 980th Hospital of the Joint Logistic Support Force of PLA. According to the debridement method adopted for the residual wounds, the patients were divided into ultrasound debridement group (34 cases, 22 males and 12 females, aged (31±13) years) and traditional debridement group (30 cases, 19 males and 11 females, aged (32±13) years). After the corresponding debridement, the wounds of patients in the two groups were selected for stamp skin grafting or large skin grafting according to the wound site and skin donor status. For unhealed wounds after stage Ⅰ surgery, secondary debridement and skin grafting were be performed, with the wound debridement methods in the 2 groups being the same as those of stage Ⅰ, respectively. On postoperative day 3, drug-sensitive test was used to detect the bacteria in the wound and the positive rate of bacteria was calculate. On postoperative day 7, the survival rate of skin slices in wound and the incidence of subcutaneous hematoma were calculated. At discharge, wound healing time and debridement times of patients were counted, and the secondary debridement rate was calculated. Data were statistically analyzed with independent sample t test or chi-square test. Results: On postoperative day 3, the wounds in ultrasound debridement group were infected with Staphylococcus aureus in 2 cases and Pseudomonas aeruginosa in 2 cases, and the wounds in traditional debridement group were infected with Staphylococcus aureus in 5 cases, Pseudomonas aeruginosa in 3 cases, Acinetobacter baumannii in 1 cases, Klebsiella pneumoniae in 1 cases, and Enterobacter cloacae in 1 cases. The positive rate of bacteria of wound in ultrasound debridement group was significantly lower than that in traditional debridement group (χ2=5.51, P<0.05). On postoperative day 7, the survival rate of skin grafts in ultrasound debridement group was (92±5) %, which was significantly higher than (84±10) % in traditional debridement group (χ2=6.78, P<0.01); the incidence of subcutaneous hematoma in ultrasound debridement group was 17.6% (6/34), which was significantly lower than 40.0%( 12/30) in traditional debridement group, χ2=3.94, P<0.05. At discharge, the wound healing time in ultrasound debridement group was (11.0±2.0) d, which was significantly shorter than (13.0±3.1) d in traditional debridement group (t=3.81, P<0.01); the secondary debridement rate of wounds in ultrasound debridement group was 2.9% (1/34), which was significantly lower than 20.0% (6/30) in traditional debridement group (χ2=4.76, P<0.05). Conclusions: Ultrasound debridement method can significantly reduce the bacterial load of residual burn wounds, reduce postoperative hematoma formation, and promote the survival of skin grafts to shorten the course of disease of patients.

Clinical characteristics and diagnosis and treatment strategies of patients with severe traumatic aortic injury / 中华心血管病杂志

Objective: To investigate the clinical characteristics and diagnosis and treatment strategies of patients with severe traumatic aortic injury (TAI). Methods: A total of 25 patients with TAI, who hospitalized in our hospital between August 2005 to March 2021 and underwent thoracic aortic endovascular repair (TEVAR), were included in this retrospective study. According to the time from admission to TEVAR, the patients were divided into emergency TEVAR group (14 cases, TEVAR within 24 h of admission) and elective TEVAR group (11 cases, patients underwent surgery or fracture reduction and fixation first for serious injuries and then underwent TEVAR more than 24 h after admission). The general clinical data of patients, injury severity score (ISS), time from admission to intervention, total hospital stay, the proportion of closed chest drainage and the proportion of abdominal organ repair were obtained and compared. Clinical follow-up and 1-year postoperative aortic computed tomography angiography (CTA) were performed on the patients. Death, the occurrence of aortic adverse events and injury recovery were followed up and recorded. Results: The mean age of these 25 TAI patients was (41.4±14.4) years, 20 patients were males (80.0%). 21 patients (84.0%) had persistent chest and back pain, 17 (68.0%) had pleural effusion and 5 (20.0%) had mediastinal hematoma. The injury severity score (ISS) was significantly higher in the elective TEVAR group than in the emergency TEVAR group (24.9±14.4 vs. 35.5±9.3, P=0.044). The time from admission to intervention ((1.0±0.0) d vs. (3.4±0.9) d, P<0.001], the time from admission to TEVAR ((1.0±0.0) d vs. (11.5±13.8) d, P=0.030) and total hospital stay ((6.1±2.3) d vs. (26.8±7.7) d, P<0.001) were significantly longer in elective TEVAR group than in emergency TEVAR group. The proportion of thoracic closed drainage was significantly lower in the elective TEVAR group than in the emergency TEVAR group (9 (64.3%) vs. 2 (18.2%), P=0.042). The proportion of abdominal organ repair was significantly higher than in the emergency TEVAR group (0 vs. 4 (36.4%), P=0.026). All of 25 patients were discharged alive and followed up for (84.0±30.5) months. All patients survived and completed 1-year postoperation CTA. There were no aortic adverse events occurred, and no complications after surgery, and the fractures and organ injuries healed well. Conclusions: The clinical characteristics of severe TAI are acute multi-injuries combined with persistent chest and/or back pain, pleural effusion, and mediastinal hematoma. Timely diagnosis and treatment are important factors for the outcome. The treatment strategy for multi-injuries should give priority to dealing with life-threatening injuries. TEVAR is the primary treatment strategy for severe TAI and is related to satisfactory outcomes.

Effects of MCC950 on nerve injury in rats with intracerebral hemorrhage / 中国应用生理学杂志

Objective: To investigate the effects of the pyrin domain-containing protein 3 (NLRP3) inflammasome inhibitor MCC950 on nerve injury in rats with intracerebral hemorrhage(ICH). Methods: Seventy-two SD rats were randomly divided into three groups (n=24): Sham group, ICH group and MCC950 group. ICH group and MCC950 group rats were injected with autogenous non-anticoagulant blood to establish ICH model, and then the rats in MCC950 group were intraperitoneally injected with MCC950 at the dose of 10 mg/kg(2 mg/ml) for 3 days after ICH model was established. Seventy-two hours after the establishment of the model, the forelimb placement test, the corner test and mNSS score were performed to observe the neurological function of the rats with ICH. The volume of hematoma was observed in fresh brain tissue sections. HE staining was used to observe the pathological changes of brain tissue. The dry-wet weight ratio was calculated to evaluate the changes of brain tissue edema. The degeneration of neurons was observed by FJC staining. The neuronal apoptosis was observed by TUNEL staining. The protein expression and activation levels of NLRP3, ASC, caspase-1, IL-1β, IL-18 and GSDMD were determined by Western blot. Results: Compared with sham group, the percentage of successful placement of left forelimb and left turn was decreased significantly (P＜0.01, P＜0.05), mNSS score was increased significantly (P＜0.01) in ICH group. Hematoma volume was increased significantly, the number of microglial cells around the hematoma was increased, the number of neurons was decreased, nerve cell swelled, some cells showed pyknotic necrosis, and the staining was deepened. The water content of the right base was increased significantly (P＜0.05). The number of FJC positive and TUNEL positive cells around the hematoma was increased significantly (P＜0.05). The levels of NLRP3, ASC, caspase-1, pro-caspase-1, caspase-1/pro-caspase-1 ratio, GSDMD-N, GSDMD, GSDMD-N/GSDMD ratio, IL-1β and IL-18 were increased significantly (P＜0.01, P＜ 0.05). Compared with ICH group, the percentage of successful placement of left forelimb and left turn was increased significantly in MCC950 group (P＜0.05), while the mNSS score and the volume of hematoma were decreased significantly (P＜0.01), the swelling degree of nerve cells around the hematoma was reduced significantly, and the number of pyrotic necrotic cells was decreased. The water content of the right base was decreased significantly (P＜0.05), and the number of FJC positive and TUNEL positive cells around the hematoma was decreased significantly (P＜0.05). The levels of NLRP3, ASC, caspase-1, pro-caspase-1, caspase-1/pro-caspase-1 ratio, GSDMD-N, GSDMD, GSDMD-N/GSDMD ratio, IL-1β and IL-18 were decreased significantly (P＜0.05). Conclusion: MCC950 can ameliorate nerve injury after ICH by inhibiting NLRP3 inflammasome mediated inflammation and pyroptosis.

Hematoma espontáneo del músculo psoas ilíaco secundario a anticoagulación como causa de muerte: reporte de caso / Spontaneous hematoma of the iliac psoas muscle secondary to anticoagulation as cause of death: case report

Resumen El uso de tromboprofilaxis posterior a las cirugías cervicales es una práctica recomendada a nivel mundial debido a que este tipo de pacientes presentan un mayor riesgo de desarrollar tromboembolismos venoso. Dentro de los efectos adversos de esta terapia se ha descrito la epistaxis, hematuria, formación de hematomas y sangrados. El hematoma espontáneo del músculo psoas iliaco, se considera una entidad poco frecuente, que suele asociarse a alteraciones de la coagulación, hemofilia o discrasias sanguíneas y como terapia anticoagulante, siendo este último la principal causa. En la autopsia médico legal, el hematoma del músculo psoas iliaco, suele ser un hallazgo incidental y en la mayoría de casos no contribuye en la causa de muerte. En el presente artículo se expone el caso de un masculino conocido con una enfermedad renal crónica, el cual desarrolló un hematoma espontáneo del músculo psoas iliaco, secundario al uso de enoxaparina como tromboprofilaxis posterior a una intervención quirúrgica en el cuello, que lo condujo a un shock mixto ocasionándole la muerte.

Abstract The use of thromboprophylaxis after cervical surgeries is a recommended practice worldwide due to the fact that these types of patients have a higher risk of developing venous thromboembolisms. Among the adverse effects of this therapy it has been described epistaxis, hematuria, formation of hematomas and bleeding. Spontaneous hematoma of the iliac psoas muscle is considered a rare entity, which is usually associated with coagulation disorders, hemophilia or blood dyscrasias and anticoagulant therapy, the latter being the main cause. In the medico-legal autopsy, the hematoma of the iliopsoas muscle is usually an incidental finding and in most cases does not contribute to the cause of death. This article describes the case of a male known with chronic kidney disease, who developed a spontaneous hematoma of the iliac psoas muscle, secondary to the use of enoxaparin as thromboprophylaxis after a surgical intervention in the neck, which led to a mixed shock causing death.

Diagnóstico posnatal de hematoma de cordón umbilical: reporte de un caso / Postnatal diagnosis of umbilical cord hematoma: case report

ANTECEDENTES: El hematoma espontáneo del cordón umbilical es una complicación rara del embarazo que representa una causa grave de morbilidad y mortalidad fetal. Se han descrito numerosos factores de riesgo, pero aún se desconoce su etiología exacta. CASO CLÍNICO: Mujer de 28 años, en su octava gestación, que consultó en urgencias por disminución de los movimientos fetales de varias horas de evolución tras una caída accidental traumática. La monitorización fetal mostró un patrón cardiotocográfico no tranquilizador, con disminución de la variabilidad y sin aceleraciones. Se realizó una cesárea urgente, sin complicaciones, con el nacimiento de un varón vivo de 4560 g, con Apgar 8/10/10 y pH de sangre de cordón umbilical 7.08, que precisó ingreso en la unidad de neonatología por hallazgo de un soplo cardíaco. Tras el alumbramiento se objetivó una gran colección hemática en el cordón umbilical. MÉTODO: Se aplicó una estrategia de búsqueda sistemática en Medline, PubMed y Cochrane de todos los artículos en inglés y español que tuvieran como palabras clave "Umbilical", "Cordón" y "Hematoma". RESULTADOS: Se encontraron 13 publicaciones de 15 casos de hematoma del cordón umbilical en los años 2008-2020. Se realizó una revisión sistemática de los informes de casos descritos en los últimos 12 años en la literatura para evaluar la epidemiología, los factores predisponentes, los resultados potenciales, el diagnóstico prenatal y el manejo clínico. CONCLUSIONES: Debido a la rareza de esta afección, se deben informar todos los casos nuevos de hematoma del cordón umbilical para mejorar el conocimiento de los factores predisponentes, el diagnóstico prenatal y el manejo clínico.

BACKGROUND: Spontaneous umbilical cord hematoma is a rare complication of pregnancy which represents a serious cause of fetal morbidity and mortality. There are many risk factors, but the exact etiology is still unknown. CASE REPORT: 28-year-old woman, eighth gestation, who consulted due to decreased fetal movements of several hours of evolution after traumatic accidental fall. Fetal monitoring showed a non-reassuring cardiotocographic pattern, with decreased fetal variability, without accelerations. An emergency cesarean section was performed without complications, with the birth of a living male weighing 4560 grams, with an 8/10/10 Apgar test, and an arterial pH of the umbilical cord 7.08, which required admission to the neonatology unit. After delivery, a large blood collection was observed in the umbilical cord. METHOD: A systematic search strategy was applied to several electronic bibliographic databases: Medline, PubMed and Cochrane. Key words used were "Umbilical", "Cord", "Hematoma". RESULTS: 13 publications of 15 cases of umbilical cord hematoma were reported in the years 2008-2020. A systematic review of the reports of cases, described in the last twelve years in the literature was carried out to evaluate the epidemiology, predisposing factors, potential results, prenatal diagnosis and clinical management of this phenomenon. CONCLUSIONS: Due to the rarity of this condition, every new case of umbilical cord hematoma should be reported in order to improve the knowledge of predisposing factors, prenatal diagnosis, and clinical management.

Hematoma de tabique: informe de dos casos pediátricos / Septal hematoma: Report of two pediatric cases

Los hematomas y abscesos septales constituyen una urgencia en rinología y requieren tratamiento quirúrgico temprano debido al riesgo de complicaciones infecciosas, funcionales y estéticas. Suelen aparecer como consecuencia de un traumatismo nasal, aunque también se han descrito en relación con otros desencadenantes. La acumulación de sangre o pus entre el mucopericondrio y el cartílago septal causa lesión por necrosis avascular en el cartílago y la destrucción de este.Desde el punto de vista clínico, se presenta como insuficiencia ventilatoria nasal y dolor facial. Con menor frecuencia, el motivo de consulta es deformidad del dorso nasal, epistaxis, rinorrea purulenta y fiebre.Se presentan en este trabajo dos casos clínicos con diagnóstico de hematoma septal que requirieron cirugía.

Hematomas and septal abscesses are an emergency in rhinology and require early surgical treatment due to the risk of infectious, functional, and aesthetic complications. They generally occur as a consequence of nasal trauma, although they have also been described in relation to other triggers. Accumulation of blood or pus between the mucoperichondrium and septal cartilage, causes avascular necrosis injury to the cartilage with cartilage destruction.Clinically it presents as nasal ventilatory insufficiency and facial pain. In a lower percentage, the reason for consultation was nasal dorsal deformity, epistaxis, purulent rhinorrhea and fever.We present two clinical cases with septal hematoma. Both required surgery.

Hematoma duodenal posvideoendoscopia digestiva alta para diagnóstico de enfermedad de injerto contra huésped en pediatría: a propósito de dos casos / Duodenal hematoma after upper gastrointestinal endoscopy in pediatric graft vs host disease: Report of two cases

La enfermedad de injerto contra huésped es una complicación grave que se presenta después del trasplante de médula ósea, con morbilidad y mortalidad elevadas. El patrón de oro para evaluar su compromiso gastrointestinal es la endoscopia digestiva alta y baja con toma de biopsia. El desarrollo de hematoma duodenal intramural es una complicación poco frecuente asociada con este procedimiento .Se presentan dos casos de hematoma duodenal intramural posendoscopia en pacientes con trasplante y sospecha de enfermedad injerto contra huésped que presentaron un cuadro agudo de dolor abdominal y sangrado intestinal. El diagnóstico se realizó por tomografía y recibieron tratamiento conservador, con un resultado favorable. En ambos casos, el diagnóstico de enfermedad injerto contra huésped gastrointestinal se hizo a través de las biopsias colónicas con histología duodenal normal, lo que sugiere evitar la toma de muestras duodenales para prevenir esta grave complicación en pacientes de alto riesgo y, de este modo, disminuir la morbilidad.

Graft versus host disease is a serious complication that occurs following bone marrow transplant with significant morbidity and mortality. The gold standard to diagnose gastrointestinal graft versus host disease is upper and lower gastrointestinal endoscopy with histological validation. The development of intramural duodenal hematoma is a rare complication associated with this procedure. We present two cases of intramural duodenal haematoma after duodenal biopsies in bone marrow transplant patients that presented clinically with severe abdominal pain and intestinal bleeding. In both cases, CT scans confirmed the diagnosis and they were treated conservatively with favorable outcomes.Final diagnosis of gastrointestinal graft versus host disease was based on the colonic samples with normal duodenal histoarchitecture, which could lead to avoiding duodenal samples in future patients in order to prevent this serious complication and thus diminish morbidity.

Periorbital ecchymosis and subconjunctival hemorrhage due to leech therapy for headache / Equimose periorbital e hemorragia subconjuntival devido à terapia com sanguessugas para dor de cabeça

ABSTRACT A 62-year-old woman was admitted to our clinic with the complaints of periorbital ecchymosis and subconjunctival hemorrhage that are visible, especially on the right eye. We noted that her complaints began the day after she underwent leech therapy on the glabella area for headache. On the glabella, 2 leech bites were observed close to the right side. Examination revealed ecchymosis on the bilateral eyelids and subconjunctival hemorrhage on the inferolateral and medial limbus on the right eye. No treatment was initiated, rather control measures were recommended. The follow-up after 1 month revealed that the patient's complaints had disappeared.(AU)

RESUMO Uma paciente de 62 anos procurou nosso ambulatório com queixas de equimose periorbital e hemorragia subconjuntival, visíveis principalmente no olho direito. Descobrimos que suas queixas começaram no dia seguinte a um tratamento para dor de cabeça com sanguessugas na área da glabela. Na glabela, 2 mordidas de sanguessuga foram encontradas próximas ao lado direito. Durante os exames da paciente, foram detectadas equimoses nas pálpebras bilaterais e hemorragia subconjuntival no limbo ínfero lateral e medial do olho direito. Nenhum tratamento foi iniciado, sendo recomendado apenas controle. No acompanhamento, observou-se que as queixas da paciente desapareceram em cerca de um mês.(AU)

Hematoma subcapsular hepático pos-CPRE: reporte de caso y revisión de la literatura / Subcapsular hepatic hematoma after ERCP. Case report and literature review

Resumen Presentamos el caso de un paciente de 68 años, sin antecedentes de importancia, que por su cuadro clínico y resultados paraclínicos fue clasificado con riesgo intermedio para coledocolitiasis. En efecto, por medio de colangiorresonancia se realizó el diagnóstico confirmatorio. Fue llevado a colangiopancreatografía retrograda endoscópica en dos ocasiones -la primera fallida por papila intradiverticular-; en el segundo intento (exitoso con extracción del lito), el paciente presentó evolución posprocedimiento tórpida, con marcado dolor abdominal y anemización. Fue llevado a tomografía de abdomen con contraste, la cual confirmó el diagnóstico de hematoma subcapsular. Se decidió implementar el manejo conservador y se logró un control adecuado del sangrado.

Abstract This is the case of a 68-year-old female patient, with no relevant history, who was classified as intermediate risk for choledocholithiasis due to her symptoms and lab test results. The diagnosis was confirmed by means of cholangioresonance. She was taken to ERCP on two occasions; the first failed due to intradiverticular papilla, and during the second attempt (successful with the removal of the stone), the patient had a torpid post-procedure evolution, with marked abdominal pain and anemization. An abdominal tomography with contrast was performed, which confirmed the diagnosis of subcapsular hematoma. A conservative management was implemented, achieving adequate bleeding control.

The effect of hematoma puncture drainage before decompressive craniectomy on the prognosis of hypertensive intracerebral hemorrhage with cerebral hernia at a high altitude / 中华创伤杂志(英文版)

PURPOSE@#Rapid decompressive craniectomy (DC) was the most effective method for the treatment of hypertensive intracerebral hemorrhage (HICH) with cerebral hernia, but the mortality and disability rate is still high. We suspected that hematoma puncture drainage (PD) + DC may improve the therapeutic effect and thus compared the combined surgery with DC alone.@*METHODS@#From December 2013 to July 2019, patients with HICH from Linzhi, Tibet and Honghe, Yunnan Province were retrospectively analyzed. The selection criteria were as follows: (1) altitude ≥1500 m; (2) HICH patients with cerebral hernia; (3) Glascow coma scale score of 4-8 and time from onset to admission ≤3 h; (4) good liver and kidney function; and (5) complete case data. The included patients were divided into DC group and PD + DC group. The patients were followed up for 6 months. The outcome was assessed by Glasgow outcome scale (GOS) score, Kaplan-Meier survival curve and correlation between time from admission to operation and prognosis. A good outcome was defined as independent (GOS score, 4-5) and poor outcome defined as dependent (GOS score, 3-1). All data analyses were performed using SPSS 19, and comparison between two groups was conducted using separate t-tests or Chi-square tests.@*RESULTS@#A total of 65 patients was included. The age ranged 34-90 years (mean, 63.00 ± 14.04 years). Among them, 31 patients had the operation of PD + DC, whereas 34 patients underwent DC. The two groups had no significant difference in the basic characteristics. After 6 months of follow-up, in the PD + DC group there were 8 death, 4 vegetative state, 4 severe disability (GOS score 1-3, poor outcome 51.6 %); 8 moderate disability, and 7 good recovery (GOS score 4-5, good outcome 48.4 %); while in the DC group the result was 15 death, 6 vegetative state, 5 severe disability (poor outcome 76.5 %), 4 moderate disability and 4 good recovery (good outcome 23.5 %). The GOS score and good outcome were significantly less in DC group than in PD + DC group (Z = -1.993, p = 0.046; χ@*CONCLUSION@#PD + DC treatment can improve the good outcomes better than DC treatment for HICH with cerebral hernia at a high altitude.

Clinical profiles and outcomes of acute type A aortic dissection and intramural hematoma in the current era: lessons from the first registry of aortic dissection in China / 中华医学杂志(英文版)

BACKGROUND@#Acute type A aortic dissection (ATAAD) and acute type A intramural hematoma (ATAIMH) are life-threatening diseases with high mortality. To better understand their clinical features in the Chinese population, we analyzed the data from the first Registry of Aortic Dissection in China (Sino-RAD) to promote the understanding and management of the diseases.@*METHODS@#All patients with ATAAD and ATAIMH enrolled in Sino-RAD from January 1, 2012 to December 31, 2016 were involved. The data of patients' selection, history, symptoms, management, outcomes, and postoperation complications were analyzed in the study. The continuous variables were compared using the Student's t test for normal distributions and the Mann-Whitney U test for non-normal distributions. Categorical variables were compared using the Chi-square test or Fisher exact test.@*RESULTS@#A total of 1582 patients with ATAAD and 130 patients with ATAIMH were included. The mean age of all patients was 48.4 years. Patients with ATAAD were significantly younger than patients with ATAIMH (48.9 years vs. 55.6 years, P < 0.001). For the total cohort, males were dominant, but the male ratio of patients with ATAAD was significantly higher compared to those with ATAIMH (P = 0.01). The time range from the onset of symptom to hospitalization was 2.0 days. More patients of ATAIMH had hypertension than that of ATAAD (82.3% vs. 67.6%, P < 0.05). Chest and back pain were the most common clinical symptoms. Computerized tomography (CT) was the most common initial diagnostic imaging modality. 84.7% received surgical treatment and in-hospital mortality was 5.3%. Patients with ATAAD mainly received surgical treatment (89.6%), while most patients with ATAIMH received medical treatment (39.2%) or endovascular repair (35.4%).@*CONCLUSIONS@#Our study suggests that doctors should comprehensively use clinical examination and genetic background screening for patients with ATAAD and ATAIMH and further shorten the time range from symptoms onset to intervention, achieving early diagnosis and treatment, thereby reducing the mortality rate of patients with aortic dissection in China. We should standardize the procedures of aortic dissection treatment and improve people's understanding. Meanwhile, the curing and transferring efficiency should also be improved.

Reporte de caso: hematoma epidural supra e infratentorial en paciente pediátrico / Case report: supra and infratentorial epidural hematoma in a pediatric patient

El traumatismo craneoencefálico es una causa común de morbi-mortalidad en la población pediátrica, sus lesiones secundarias como los hematomas epidurales son frecuentemente hallados, pero en su localización de la fosa posterior solo representa el 5% y son de alto riesgo de presentar complicaciones; además el hematoma supra e infratentorial simultáneo es muy poco frecuente. En el presente trabajo daremos a conocer el manejo quirúrgico de alto riesgo de un paciente con un hematoma supra e infratentorial de gran volumen, describiendo las posibles complicaciones y observando la evolución. Se realizó craneotomía supratentorial y una craniectomía sub-occipital para evacuación de hematoma. El paciente se recuperó satisfactoriamente mostrando mejoría en el postoperatorio inmediato, siendo dado de alta recuperando la función global(AU)

Traumatic Head Injury is a common cause of morbidity and mortality in the pediatric population. Its secondary lessons, such as epidural hematomas, are frequently found, but in the posterior fossa it only represents 5% and they are at high risk of complications; in addition, simultaneous supra and infratentorial hematoma is very rare. In the present work, we will present the high-risk surgical management of a patient with a large volume supraand infratentorial hematoma, describing the possible complications and observing the evolution. Supratentorial craniotomy and sub-occipital craniectomy were performed to evacuate the hematoma. The patient recovered satisfactorily showing improvement in the immediate postoperative period, being discharged recovering global function(AU)

Pharmacological Activation of RXR-α Promotes Hematoma Absorption via a PPAR-γ-dependent Pathway After Intracerebral Hemorrhage / 神经科学通报·英文版

Endogenously eliminating the hematoma is a favorable strategy in addressing intracerebral hemorrhage (ICH). This study sought to determine the role of retinoid X receptor-α (RXR-α) in the context of hematoma absorption after ICH. Our results showed that pharmacologically activating RXR-α with bexarotene significantly accelerated hematoma clearance and alleviated neurological dysfunction after ICH. RXR-α was expressed in microglia/macrophages, neurons, and astrocytes. Mechanistically, bexarotene promoted the nuclear translocation of RXR-α and PPAR-γ, as well as reducing neuroinflammation by modulating microglia/macrophage reprograming from the M1 into the M2 phenotype. Furthermore, all the beneficial effects of RXR-α in ICH were reversed by the PPAR-γ inhibitor GW9662. In conclusion, the pharmacological activation of RXR-α confers robust neuroprotection against ICH by accelerating hematoma clearance and repolarizing microglia/macrophages towards the M2 phenotype through PPAR-γ-related mechanisms. Our data support the notion that RXR-α might be a promising therapeutic target for ICH.
