Tratamiento endoscópico del sangrado digestivo alto por úlcera péptica / Endoscopic treatment of the high digestive bleeding by peptic ulcer

RESUMEN Introducción: la hemorragia digestiva alta ocurre por una lesión sangrante localizada entre el esfínter esofágico superior y el ángulo de Treitz. Objetivo: determinar el comportamiento del tratamiento endoscópico del sangrado digestivo alto por úlcera péptica, en el departamento de Gastroenterología del Hospital Universitario Comandante "Faustino Pérez". Materiales y métodos: se realizó un estudio descriptivo, prospectivo para evaluar el resultado del tratamiento endoscópico en el sangrado digestivo alto por úlcera péptica en el Hospital Universitario Comandante "Faustino Pérez" de Matanzas, de enero del 2016 a febrero del 2018. El tratamiento endoscópico fue la inyectoterapia con epinefrina al 1:10000. Se analizaron las variables: grupo de edades, sexo, resultado del tratamiento endoscópico, estigmas endoscópicos de sangrado, recidiva hemorrágica, mortalidad directa, necesidad de cirugía, estadía hospitalaria y cantidad de unidades transfusionales. Resultados: se constató un predominio de pacientes masculinos (87.5 %), menores de 60 años (70%). Prevalecieron los pacientes con estigmas endoscópicos de sangrado activo venoso (45%). La terapia endoscópica tuvo un resultado satisfactorio (92.5%) en su mayoría. La ocurrencia de resangrado (45%), mortalidad directa por hemorragia digestiva, promedio de estadía hospitalaria, cantidad de unidades transfusionales y necesidad de intervención quirúrgica de urgencia (17.5%), resultó similar a los estudios reportados, demostrando que la inyectoterapia endoscópica aún constituye una opción eficaz si no se cuenta con otras terapias endoscópicas. Conclusiones: la mayoría de los casos tratados con inyectoterapia endoscópica tuvieron un sangrado activo venoso o Forrest IB que fue satisfactoria. La inyectoterapia no satisfactoria fue en pacientes con sangrado activo. La mortalidad directa relacionada con el sangrado fue infrecuente y en relación con el sangrado arterial. Se demostró que la inyectoterapia endoscópica aún constituye una opción eficaz si no se cuenta con otras terapias endoscópicas (AU).

SUMMARY Introduction: high digestive bleeding happens due to a bleeding lesion located between the upper anatomical sphincter of the esophagus and the angle of Treitz. Objective: to determine the endoscopic treatment behavior of high digestive bleeding caused by peptic ulcer, in the department of Gastroenterology of the University Hospital "Comandante Faustino Perez". Materials and methods: a prospective descriptive study was carried out to evaluate the result of the endoscopic treatment in high digestive bleeding caused by peptic ulcer in the University Hospital "Comandante Faustino Perez", of Matanzas, from January 2016 to February 2018. The endoscopic treatment was injecto-therapy with epinephrine at 1:10000. The analyzed variables were: age group, sex, result of the endoscopic treatment, bleeding endoscopic stigma, hemorrhagic relapse, direct mortality, surgery necessity, hospital staying, and quantity of transfusion units. Results: male patients (87.5 %), aged less than 60 years predominated. Patients with endoscopic stigma of venous active bleeding (45 %) prevailed. In most of cases, endoscopic therapy achieved satisfactory results (92.5 %). The authors found that bleeding relapse (45 %), direct mortality by digestive hemorrhage, average hospital staying, quantity of transfusion units and necessity of urgent surgeries (17.5 %) were similar to those reported in other studies. Conclusions: most cases treated with endoscopic injectotherapy had active venous or Forrest IB bleeding and treatment was satisfactory. Therapy was unsatisfactory in patients with active bleeding. The direct mortality related to bleeding was infrequent, and related to arterial bleeding. It was showed that endoscopic injectotherapy is still an efficacious option if other endoscopic therapies are not available (AU).

Tratamento endovascular de fístula tronco arterial braquiocefálico-traqueal: relato de caso e revisão de literatura / Endovascular management of tracheo-innominate artery fistula: a case report and literature review

A fístula do tronco arterial braquiocefálico-traqueal é uma complicação pouco frequente da traqueostomia, com incidência entre 0,1 e 1%, porém com alta mortalidade nos casos não tratados. Sinais precoces incluem desde sangramento autolimitado a hemorragia maciça com choque hipovolêmico. A espessura da cânula de traqueostomia, seu posicionamento junto à parede traqueal e a pressão do balonete traqueal podem lesionar a mucosa e precipitar seu desenvolvimento. Descrevemos o caso de paciente do sexo feminino, 14 anos, traqueostomizada aos oito anos após traumatismo craniencefálico. Evoluiu após esse período com estenose subglótica e necessidade de sessões de dilatação por seis anos. No quinto ano das sessões, apresentou hemoptise de repetição, inicialmente tratada por cirurgia com prótese de politetraflouroetileno expandido. Um ano depois, apresentou novo sangramento com repercussão hemodinâmica, controlada pela técnica endovascular, e nova cirurgia foi programada em caráter eletivo. Após a segunda cirurgia, houve seis meses de acompanhamento clínico ambulatorial, sem novas complicações

Tracheo-innominate artery fistula (TIF) is a rare complication of tracheostomy, with incidence ranging from 0.1 to 1%, but mortality is high in untreated cases. Early signs range from self-limited bleeding to massive hemorrhage with hypovolemic shock. The caliber of the tracheostomy cannula, its position in contact with the tracheal wall, and tracheal cuff pressure can traumatize the mucosa and trigger development of a TIF. We describe the case of a 14-year-old female patient who had been tracheostomized at the age of eight because of head trauma. She later developed subglottic stenosis requiring dilation sessions for six years. During the fifth year of these sessions, she presented repetitive hemoptysis, initially treated by surgery to implant an expanded polytetrafluoroethylene graft. One year later, she had an intense hemorrhage, which was controlled using endovascular techniques followed by definitive surgery, performed electively. The patient was followed up for six months, without complications

Un caso pediátrico de hemolacria / A pediatric case of haemolacria

Introducción: la presencia de lágrimas con sangre -o hemolacria- es un hecho infrecuente en la práctica clínica, y ha sido denominada con distintas acepciones en la literatura médica. Las causas que originan este signo son múltiples, y comprenden desde trastornos locales en el globo ocular, hasta enfermedades sistémicas, además de las provocadas en forma artificial y en otras. En ocasiones su etiología no se ha podido demostrar. Presentación del caso: adolescente, mestiza, de 16 años de edad que fue remitida al Hospital Docente Pediátrico del Cerro por el policlínico de su área de salud, porque presentó lágrimas con sangre con epistaxis acompañada de cefaleas y calambres en extremidades inferiores, además de referir un síndrome de inmunodeficiencia adquirida desde los 13 años. Durante su estadía hospitalaria se constató en dos ocasiones hemolacria con epistaxis. Los exámenes complementarios realizados para diagnosticar algún trastorno de la coagulación, enfermedad local o sistémica no transmisible, resultaron normales. Se indicó tratamiento con antirretrovirales para su afección de base. Se explicó la posible fisiopatología de este fenómeno. Conclusiones: la causa de esta entidad en la presente comunicación queda por precisar, y es el primer caso pediátrico reportado en Cuba(AU)

Introduction: the presence of tears with blood -or haemolacria- is an uncommon event in clinical practice which has been defined in several different manners in medical literature. The causes giving rise to this sign are many, ranging from local disorders in the eyeball to systemic diseases, alongside those brought about by artificial agents and others. On occasion it has not been possible to determine its etiology. Case presentation: a mulatto 16-year-old female adolescent was referred by the polyclinic in her health area to the Pediatric University Hospital in the municipality of Cerro with bloody tears and epistaxis accompanied by headaches and cramp in her lower limbs. The patient stated she had suffered from an acquired immunodeficiency syndrome since the age of 13. During her stay in hospital two episodes of haemolacria with epistaxis could be observed. The complementary tests performed to diagnose some other coagulation disorder, local condition or non-communicable systemic disease were all normal. Treatment with antiretrovirals was indicated for her underlying disease. The possible physiopathology of the phenomenon was explained. Conclusions: the cause of the condition discussed in the present communication is still to be determined. This is the first pediatric case of haemolacria reported in Cuba(AU)

Edema agudo hemorrágico de la infancia: Lesiones alarmantes de un cuadro benigno. Reporte de caso / Acute hemorrhagic edema of infancy: alarming lesions of a benign condition. Case report

Se reporta un caso de edema agudo hemorrágico de la infancia, en un lactante de 18 meses, después de un episodio de otitis media. El cuadro comenzó con máculas eritematosas en los muslos, seguidas de lesiones purpúricas en los brazos, las piernas y edema en los tobillos. Se interpretó, inicialmente, como urticaria, por lo que recibió esteroides. Sin embargo, las características clínicas fueron de edema agudo hemorrágico de la infancia, una vasculitis leucocitoclástica benigna que se presenta en niños de entre 4 y 24 meses y que se caracteriza por fiebre, máculas y lesiones purpúricas. Estas se ubican, principalmente, en la cara, los lóbulos de las orejas y las extremidades, y se asocian, muchas veces, a edema. Los diagnósticos diferenciales son eritema multiforme, urticaria, vasculitis inducida por droga, enfermedad de Kawasaki, eccema infectado, meningococcemia y maltrato infantil, algunas de ellas, con riesgo de mortalidad. El manejo es conservador, sin embargo, los esteroides podrían ser una opción terapéutica.

We report a case of acute hemorrhagic edema of infancy in an 18-month-old boy after an episode of otitis media. The clinical presentation begins with skin erythematous macules on the thighs, followed by purpuric lesions in arms, legs, and ankle edema. It was initially interpreted as urticaria, whereby steroids were indicated. However, the clinical feature was acute hemorrhagic edema of infancy, a benign leukocytoclastic vasculitis that occurs in children between 4 and 24 months of age and is characterized by fever, large purpuric palpable target-like skin lesions affecting the face, lobes of the ears, limbs and frequently associated with edema. Differential diagnosis includes erythema multiforme, hemorrhagic urticaria, drug-induced vasculitis, Kawasaki disease, infected eczema, sepsis (either meningococcal or non-meningococcal) and child abuse. Some of them have risk of mortality. Management is conservative, however, steroids may be a therapeutic option.

A new era of thromboelastometry / A nova era da tromboelastometria

ABSTRACT Severe hemorrhage with necessity of allogeneic blood transfusion is common complication in intensive care unit and is associated with increased morbidity and mortality. Prompt recognition and treatment of bleeding causes becomes essential for the effective control of hemorrhage, rationalizing the use of allogeneic blood components, and in this way, preventing an occurrence of their potential adverse effects. Conventional coagulation tests such as prothrombin time and activated partial thromboplastin time present limitations in predicting bleeding and guiding transfusion therapy in critically ill patients. Viscoelastic tests such as thromboelastography and rotational thromboelastometry allow rapid detection of coagulopathy and goal-directed therapy with specific hemostatic drugs. The new era of thromboelastometry relies on its efficacy, practicality, reproducibility and cost-effectiveness to establish itself as the main diagnostic tool and transfusion guide in patients with severe active bleeding.

RESUMO A hemorragia grave com necessidade de transfusão de sangue e componentes é uma complicação frequente na unidade de terapia intensiva e está associada ao aumento da morbidade e da mortalidade. A identificação adequada e o tratamento precoce da causa específica da coagulopatia tornam-se fundamentais para o controle efetivo da hemorragia, racionalizando a utilização de sangue e componentes, e desta forma, prevenindo a ocorrência de efeitos adversos. Testes convencionais da coagulação (tempo de ativação de protrombina e tempo de tromboplastina parcial ativada) apresentam limitações para prever sangramento e guiar a terapia transfusional em pacientes graves. Testes viscoelásticos como a tromboelastografia e tromboelastometria rotacional permitem a rápida detecção da coagulopatia e orientam a terapia de forma individualizada, alvo dirigida com drogas hemostáticas específicas. A nova era da tromboelastometria confia na sua eficácia, praticidade, reprodutibilidade e custo-eficácia para se firmar como a principal ferramenta diagnóstica e guia transfusional em pacientes com sangramento ativo grave.

Introduction: the high digestive hemorrhage is a frequent health problem in the world; it behaves the same in Cuba, in the province of Matanzas and in the hospital where the study was carried out. Currently it is considered a major cause of morbi-mortality. Objective: to determine the behavior of the high digestive bleeding in the Military Hospital of Matanzas. Materials and Methods: a descriptive research was carried out in a five-year period. It included all the patients admitted with that diagnosis and those who presented episodes of hemorrhage even if they were admitted by any other cause. The Rockall index allowed to assess the necessity of surgery, the recidivism and mortality. Results: most of the patients belonged to the intermediate risk group. Male patients were the most affected one; the group of elder people showed higher incidence. Hemorrhagic gastritis was the first cause of bleeding. Arterial hypertension was the relevant risk factor and smoking the most frequent toxic habit. Conclusions: as a relevant benefit it was showed the importance of precocious endoscopy for the diagnosis of the hemorrhage cause, treatment and prognosis. It was observed a good correlation between the patient´s prognosis at the admission and his status at the end of the treatment (AU).

Anorectal hemangioma - differential diagnosis of anal bleeding / Hemangioma anorretal - diagnóstico diferencial de sangramento anal

ABSTRACT Anorectal hemangioma is one of the rarest causes of lower gastrointestinal bleeding, but is often neglected and confused in the differential diagnosis. The clinical examination is a turning point for a correct diagnosis and management of patients, thus avoiding unnecessary procedures. The treatment of choice for this condition is surgical and intraoperative bleeding is the main complication of this therapy. The present case reports a 25-year old patient with a history of bleeding from the age of 13, being diagnosed with anorectal hemangioma, and surgically treated with resection of the affected segment and with wound synthesis by marsupialization, with a good progression postoperatively.

RESUMO O Hemangioma Anorretal é uma das mais raras causas de Hemorragia digestiva baixa, sendo muitas vezes negligenciada e confundida no diagnóstico diferencial. O exame clínico representa um ponto decisivo para correto diagnóstico e manejo do paciente, evitando realização de exames desnecessários, e o tratamento de escolha dessa patologia é cirúrgico, sendo o sangramento intraoperatorio a principal complicação dessa terapêutica. O relato de caso a seguir reporta a história de paciente com 25 anos, que apresentava sangramento desde os 13, sendo diagnosticado com Hemangioma Anorretal e tratado cirurgicamente com ressecção do segmento afetado e síntese de ferida com marsupialização, evoluindo bem no pós-operatório.

Hemorragia alveolar difusa, desafío diagnóstico y terapéutico / Diffuse alveolar hemorrhage: a diagnostic and therapeutic challenge

Diffuse alveolar hemorrhage is a syndrome causing catastrophic respiratory failure, secondary to pathophysiological processes within the natural history of a variety of diseases and clinical conditions. Should be considered a medical emergency due to the significant morbidity and mortality associated. It represents a diagnostic challenge because symptoms and signs are often nonspecific. It requires a highlevel of suspicion to early recognition, essential step towards the establishment of supportive measures and specific therapy for survival.

La hemorragia alveolar difusa es un síndrome causante de falla respiratoria catastrófica, secundario a los procesos fisiopatológicos presentes en la historia natural de varias enfermedades y condiciones clínicas. Debe considerarse como una emergencia médica debido a la significativa morbi-mortalidad asociada. Representa un desafío diagnóstico ya que a menudo los síntomas y signos son inespecíficos, requiere un alto nivel de sospecha para el reconocimiento precoz, paso esencial para la instauración de medidas de soporte vital y terapia específica requerida para la sobrevida.

Síndrome de Münchausen por poder en otorrinolaringología / Münchausen syndrome by proxy in otorhinolaryngology

El síndrome de Münchausen por poder es una forma de maltrato infantil, con graves consecuencias para el niño afectado. El diagnóstico de esta afección constituye un desafío para los médicos por su heterogeneidad en los síntomas y signos de presentación. Variadas manifestaciones otorrinolaringológicas están descritas en esta patología. En este artículo se presenta un caso clínico de otitis media crónica con otorragia en un paciente de 2 años, donde se logró establecer el diagnóstico de síndrome de Münchausen por poder a través de la identificación de elementos incongruentes en la historia clínica y finalmente por la detección in fraganti de la agresión por parte de la madre. En esta revisión se concluye que es necesario un alto índice de sospecha para identificar esta patología, la que debe ser una preocupación habitual del equipo de salud para evitar asi consecuencias graves en estos pacientes, tales como secuelas psiquiátricas o incluso la muerte.

Münchausen's syndrome by proxy is a form of child abuse with severe consequences for the affected child. The diagnosis of this condition is a challenge for physicians due to the heterogeneity of the presentation symptoms. A lot of otorhinolaryngological manifestations have been described in this syndrome. We present a case of a 2 year old patient with chronic otitis media and otorrhagia, where we could establish the diagnosis of Münchausen's syndrome by proxy through the identifications of incongruent elements on the clinical history and finally the direct visualization of mother's aggression. In this should be a common concern for health workers to avoid severe consequences in these patients like psychiatric diseases or even death.

Contribution of ultrasonography to the diagnosis of internal bleeding in snakebite envenomation

In Africa, snakebite envenomations are frequently complicated by life-threatening hemorrhagic syndromes. The authors of the present study conducted a prospective analysis at the University Hospital of Parakou (north of Benin) for seven months (January 1 to July 31, 2014) to assess the contribution of ultrasonography to the diagnosis of internal bleedings and management of envenomation. Methods An ultrasound examination was performed in all patients with clinical envenomation regardless of its severity. The study involved 32 patients admitted to the ICU of the University Hospital of Parakou. Results The average age was 27 ± 13.9 years. The main signs of severity were: prolongation of clotting time (88 %), severe anemia (41 %), clinical hemorrhage (47 %), and shock (19 %). The ultrasound imaging showed internal hemorrhage in 18 patients (56 %). There were hematomas (22 %), hemoperitoneum (13 %) or a combination of both (22 %). The occurrence of internal bleeding and hemoperitoneum were mainly related to the delay of hospital presentation (p = 0.007) and the existence of external bleeding (p = 0.04). Thirty patients (94 %) received antivenom. Case fatality rate was 3.1 %. Conclusion Ultrasonography may help in diagnosing internal bleeding, even in patients that did not show external hemorrhages, and evaluating its importance. As a consequence, the management of snakebite victims may be significantly improved.

Hemorragia suprarrenal que se manifiesta como hematoma escrotal en el recién nacido: A propósito de un caso / Adrenal hemorrhage presenting as a scrotal hematoma in the newborn: A case report

La hemorragia suprarrenal neonatal es poco frecuente. Se presenta en el 0,2% de los recién nacidos. El 10% de los casos son bilaterales. Puede estar asociada a un traumatismo al nacimiento, peso alto al nacer o un curso neonatal complicado por hipoxia, asfixia, hipotensión o coagulopatía. El hematoma escrotal es una manifestación extremadamente rara de la hemorragia suprarrenal neonatal. La mayoría de los pacientes presentan tumefacción escrotal con coloración azulada. En los recién nacidos, la tumefacción escrotal, con o sin coloración azulada, puede deberse a diferentes causas. Comunicamos un caso inusual de hemorragia suprarrenal neonatal secundaria a asfixia perinatal, que se manifestó con un hematoma escrotal. El diagnóstico de hemorragia suprarrenal neonatal y hematoma escrotal fue ecográfico; el tratamiento conservador evitó la exploración quirúrgica innecesaria.

Neonatal adrenal hemorrhage is uncommon. It is present in 0,2% of newborns. Ten percent of the cases occur bilaterally. It can be associated with birth trauma, large birth weight, or neonatal course complicated by hypoxia and asphyxia, hypotension, or coagulopathy. Scrotal hematoma is an extremely rare manifestation of NAH. Most patients present scrotal swelling with bluish discolouration. Scrotal swelling with/without bluish discoloration in newborns may result from different causes. We report an unusual case of neonatal adrenal hemorrage secondary to perinatal asphyxia, associated with SH. Neonatal adrenal hemorrhage and scrotal hematoma were diagnosedby ultrasonography and treated by conservative treatment, avoiding unnecessary surgical exploration.
