Prevalencia de cristales de colesterol en granulomas perirradiculares de origen endodóntico / Prevalence of cholesterol crystals in periradicular granulomas of endodontic origin

Objetivos: Identificar y determinar la prevalencia de cristales de colesterol (CRCo) en granulomas perirradiculares de origen endodóntico y el tipo de reacción que provocan en los tejidos circundantes. Material y métodos: Se estudiaron con microscopía óptica 75 preparados histológicos de archivo pertenecientes a lesiones perirradiculares humanas correspondientes a piezas dentarias que habían recibido un tratamiento endodóntico pre- vio y que, según los informes que acompañaban las muestras, habían sido obtenidas mediante una apicectomía. Del total, 68 muestras fueron diagnosticadas como granulomas, mientras que los 7 restantes se diagnosticaron como quistes inflamato- rios y fueron descartadas. Resultados: 39 granulomas pertenecían a pacientes de sexo femenino con presencia de CRCo en el 58,97% de los ca- sos. Los 29 granulomas restantes pertenecían al sexo mascu- lino y presentaron CRCo en un 41,37%. La mayor proporción de CRCo fue hallada en granulomas pertenecientes a pacien- tes mayores de 62 años. Los CRCo se observaron rodeados de macrófagos y células gigantes multinucleadas, provocando una reacción a cuerpo extraño. También se observaron células espumosas en áreas circundantes. Conclusiones: La presencia de CRCo en granulomas perirradiculares de origen endodóntico provoca una reacción a cuerpo extraño que puede interferir con el proceso de re- paración posendodóntico especialmente en pacientes de edad avanzada (AU)

Aim: Identify and determine the prevalence of cholester- ol crystals (CRCo) in periradicular granulomas of endodontic origin and the type of reaction they produce in the surround- ing tissues. Material and methods: 75 archival histological preparations were studied with optical microscopy. They be- longed to human periradicular lesions corresponding to teeth that had received a previous endodontic treatment and that, according to the reports accompanying the samples, had been obtained by an apicoectomy. Of the total, 68 samples were diagnosed as granulomas, while the remaining 7 were diag- nosed as inflammatory cysts and were discarded. Results: 39 granulomas corresponded to female patients in which the presence of CRCo was observed in 58.97% of the cases. The remaining 29 granulomas were from male patients and showed CRCo in 41.37% of the cases. The highest pro- portion of CRCo was found in patients over 62 years of age. The CRCo were surrounded by macrophages and multinucle- ated giant cells causing a foreign body reaction. Foam cells were also observed in the surrounding areas. Conclusions: The presence of CRCo in periradicular granulomas of endodontic origin could be a factor interfering with periapical healing after conventional endodontic thera- py, especially in elderly patients (AU)

Observational and descriptive analysis of broken dental needles: a case series.

PURPOSE: To discuss potential causes of broken dental needles during dental anesthesia and features of this complication, including the anatomical location of fragments in tissues, symptoms, complications, and therapeutic approaches. METHODS: Twelve cases of broken dental needles occurring during dental anesthesia and subsequently referred to Hospital de Base do Distrito Federal, Brazil, between 1992 and 2019 were selected. In addition, similar cases reported in the literature over the past 50 years were reviewed. RESULTS: Needle fractures occur most frequently during inferior alveolar nerve blocks and in younger patients. The leading cause is unexpected patient movement during the anesthetic procedure. The needle fragment is most commonly found in the pterygomandibular space or the deep spaces of the head and neck region. Needle migration is a particular concern; although rare, it is unpredictable and potentially life-threatening. CONCLUSIONS: Needle fracture is an intraoperative complication which has the potential to cause severe patient damage. It is essential that practitioners have knowledge of this possible complication and understand the technical considerations for its prevention. The existing literature and the results of this case series analysis suggest that removal of the fractured needle fragment should be attempted as soon as possible.

Además, se presentan detalles del procedimiento y los resultados. El paciente recupera la audición y la normalidad anatómica.

Cyanoacrylate-based glue has a great capacity for adhering to tissue, which is a problem when it is placed in the ear canal due to the anatomy of this structure. A clinical case of a cyanoacrylate foreign body occluding the external auditory canal and the tympanic membrane is presented. The therapeutics alternatives described in the literature used in the case failed, so, it was surgically removed by drilling the glue. Details of the procedure and results are presented. The patient recovers the hearing and anatomical normality.

Divertículo de Meckel perforado por un cuerpo extraño / Meckel's Diverticulum Perforated by a Foreign Body

Introducción: El divertículo de Meckel es la anomalía congénita más frecuente del tracto gastrointestinal. Por lo general, cursa asintomático, y su diagnóstico es transoperatorio. Cuando presenta síntomas se deben a sus complicaciones, de las cuales la perforación constituye solo el 0,5 por ciento. Objetivo: Describir las características clínico-quirúrgicas de la presentación de un paciente con divertículo de Meckel perforado por cuerpo extraño. Caso clínico: Paciente adulto de 46 años de sexo masculino, piel blanca, que acude con dolor generalizado en el abdomen que se trasladó a Fosa Ilíaca Derecha, con febrícula. Se interviene quirúrgicamente y se halla divertículo de Meckel perforado por cuerpo extraño. Conclusiones: El pronóstico de esta enfermedad depende de la evolución, diagnóstico precoz y tratamiento aplicado en las distintas complicaciones, así como de la decisión de realizar tratamiento quirúrgico en los hallazgos casuales(AU)

Introduction: Meckel's diverticulum is the most frequent congenital anomaly of the gastrointestinal tract. It is generally asymptomatic, with an intraoperative diagnosis. When it presents symptoms, they are due to its complications, of which perforation accounts for only 0.5 percent. Objective: To describe the clinical-surgical characteristics of a patient who presented with a Meckel's diverticulum perforated by a foreign body. Clinical case: 46-year-old adult patient of the male sex and white skin, who presents with generalized pain in the abdomen that moved to the right iliac fossa and low-grade fever. The patient underwent surgery and a Meckel's diverticulum was found, perforated by a foreign body. Conclusions: The prognosis of this disease depends on the evolution, early diagnosis and applied treatment according to the different complications, as well as on the decision to perform surgical treatment in accidental findings(AU)

Magnet Injuries in Children: An Analysis of the National Poison Data System from 2008 to 2019.

OBJECTIVE: To examine, using the National Poison Data System (the data warehouse for poison control centers in the US), magnet foreign body injuries in pediatric patients. We sought to report demographic data, outcome data, and case trends between 2008 and 2019. STUDY DESIGN: We conducted a retrospective analysis of the National Poison Data System for patients younger than 19 years of age with a magnet "exposure," which poison centers define as an ingestion, inhalation, injection, or dermal exposure to a poison. RESULTS: A total of 5738 magnet exposures were identified. Most were male (3169; 55%), <6 years old (3572; 62%), with an unintentional injury (4828; 84%). There were 222 patients (3.9%) with a confirmed medical "effect," defined as signs, symptoms, and clinical findings not including therapeutic interventions (eg, endoscopy). There was a 33% decrease in cases from 418 (2008-2011) to 281 per year (2012-2017) after high-powered magnet sets were removed from the market. Calls subsequently increased 444% to 1249 per year (2018-2019) after high-powered magnet sets re-entered the market. Cases from 2018 and 2019 increased across all age groups and account for 39% of magnet cases since 2008. CONCLUSIONS: Significant increases in magnet injuries correspond to time periods in which high-powered magnet sets were sold, including a 444% increase since 2018. These results reflect the increased need for preventative or legislative efforts.

RESUMEN Objetivo: Determinar las características clínico-epidemiológicas del trauma ocular a globo abierto. Métodos: Se realizó un estudio descriptivo, observacional y transversal en pacientes con trauma ocular a globo abierto y afectación del segmento posterior en pacientes hospitalizados en el Servicio de Vítreo-Retina del Instituto Cubano de Oftalmología "Ramón Pando Ferrer" entre julio del año 2017 y julio de 2018. Resultados: El 68,18 por ciento de los pacientes fue menor de 50 años y el 88,64 por ciento fueron hombres. El trauma más común fue el penetrante (91,11 por ciento); el 68,89 por ciento de las lesiones ocurrió en zona 1, con predominio de las heridas menor o igual a 4 mm (75,56 por ciento). La circunstancia más común del trauma fue la laboral (50 por ciento). El mecanismo de producción predominante fue el martilleo sobre metal (71,11 por ciento); el 65,91 por ciento de los traumas ocurrieron en zona urbana; el 96,46 por ciento no usaba protección; el 57,77 por ciento tenía una agudeza visual inicial de cuenta dedo o mejor, y la presencia de cuerpo extraño intraocular ocupó el 77,78 por ciento. Conclusiones: En el trauma ocular a globo abierto predominan la edad por debajo de 50 años, el sexo masculino y los traumas penetrantes. La mayor parte se presenta de forma unilateral, durante las actividades laborales y sin protección ocular. Más de la mitad de los pacientes presentan agudeza visual inicial de cuenta dedos o mejor. Los signos oculares asociados más frecuentes son el cuerpo extraño intraocular y la catarata traumática(AU)

ABSTRACT Objective: Determine the clinical-epidemiological characteristics of open globe ocular trauma. Methods: A cross-sectional observational descriptive study was conducted of open globe ocular trauma and posterior segment damage in patients admitted to the Vitreous-Retina Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from July 2017 to July 2018. Results: Of the patients studied, 68.18 percent were under 50 years of age and 88.64 percent were men. Penetrating trauma was the most common type (91.11 percent); 68.89 percent of the lesions were found in zone 1, with a predominance of injuries smaller than or equal to 4 mm (75.56 percent). Most traumas occurred while at work (50 percent). The prevailing occupational activity being performed at the moment of the trauma was hammering on metal (71.11 percent); 65.91 percent of the traumas occurred in urban areas; 96.46 percent of the patients were not wearing the required protection equipment; 57.77 percent had an initial visual acuity of count fingers or better; and participation of foreign bodies accounted for 77.78 percent. Conclusions: In open globe ocular trauma a predominance is found of age under 50 years, male sex and penetrating traumas. Most are unilateral and occur while working without the required ocular protection. In more than half of the patients initial visual acuity is finger counting or better. The most common associated ocular signs are intraocular foreign body and traumatic cataract(AU)

[Gossypibomas in neurosurgery]. / Gossypibomas en neurocirugía.

INTRODUCTION: The term «gossypiboma¼ comes from the Latin gossypium, which refers to a genus of cotton plants, and from the Swahili word boma, which translates as «place of concealment¼. It may be mistaken for tumorous lesions or abscesses due to the way it is encapsulated, as evidenced in imaging examinations, and its variable and non-specific clinical features, which give rise to difficulty in its diagnosis and significant morbidity. AIM: To synthesise the available evidence on the presence of gossypibomas during neurosurgical procedures. DEVELOPMENT: A review was performed that included a search for articles in English and Spanish published in the last 15 years in PubMed, Ebsco Host, Embase, Mediclatina, Cochrane, Lilacs and Scopus, between January and June 2019, using the keywords «gossypiboma¼, «textiloma¼, «neurosurgery¼ and «neurosurgical procedures¼. In all, a total of 630 articles were found in the search, although, after selecting them by title and abstract, 22 case report articles were included for this review process. Altogether 36 individuals were identified, of whom 21 (58.3%) were women, and whose mean age was 56.1 years. Surgical sponges were observed as gossypibomas in 20 cases (55.6%). CONCLUSIONS: Gossypiboma is a complication secondary to surgical procedures that presents fairly unspecific signs and symptoms. The time that elapses before it appears usually ranges from a few days to several years after surgery and is correlated with multiple medical and legal implications.

TITLE: Gossypibomas en neurocirugía.Introducción. El término «gossypiboma¼ proviene del latín gossypium, que hace referencia a un género de plantas de algodón, y de la palabra kiswahili boma, que se traduce como «lugar de escondite¼. Puede confundirse con lesiones tumorales o abscesos debido a la forma de encapsulación evidenciada en los exámenes imaginológicos y su clínica variable e inespecífica, situación que genera dificultad para el diagnóstico y una morbilidad importante. Objetivo. Sintetizar la evidencia disponible sobre la presencia de gossypibomas durante la realización de procedimientos quirúrgicos en neurocirugía. Desarrollo. Se realizó una revisión en la cual se incluyó una búsqueda de artículos en inglés y castellano publicados en los últimos 15 años en PubMed, Ebsco Host, Embase, Mediclatina, Cochrane, Lilacs y Scopus, entre enero y junio de 2019, utilizando las palabras clave «gossypiboma¼, «textiloma¼, «neurosurgery¼ y «neurosurgical procedures¼. El total de artículos encontrados en la búsqueda fue de 630; sin embargo, tras la selección por título y resumen fueron 22 los artículos de informe de caso que se incluyeron. Se identificó a un total de 36 individuos, de los cuales 21 (58,3%) eran mujeres, y cuya edad media era de 56,1 años. En 20 casos (55,6%) se observaron esponjas quirúrgicas como gossypibomas. Conclusiones. El gossypiboma es una complicación secundaria a procedimientos quirúrgicos, con signos y síntomas bastante inespecíficos. Su tiempo de aparición suele oscilar entre unos cuantos días hasta varios años después de realizada la cirugía y se correlaciona con múltiples implicaciones médicas y legales.

Ultrasound examination of coelomic viscera through the plastron in stranded green sea turtles (Chelonia mydas).

Many projects have been developed in the last years for the conservation of sea turtles. Young green turtles (Chelonia mydas) often nest on the Brazilian coast. Because they nest in beaches along the coastline and islands, green turtles are susceptible to fishing and accidental ingestion of anthropogenic debris. Early detection of ingested debris is crucial for the survival of rescued sea animals. Ultrasound (US) has emerged as a viable imaging technique for visceral examination in veterinary medicine. Previous studies have suggested the left and right cervicobrachial, axillary, pre- and post-femoral areas as the only viable approaches for US examination, but the acoustic windows available for imaging of coelomic structures are limited. It is important to notice that a detailed evaluation of all gastrointestinal tracts, especially the duodenum, is crucial for detecting foreign bodies and intestinal obstructive processes, as well as obtaining essential information such as intestinal motility and heart frequency. Intestinal motility and heartbeats are not detected through radiographic examination or through the acoustic windows available so far. This study aimed to establish the viability of US examination of coelomic viscera through the plastron in stranded green turtles. Eleven young green turtles rescued by the GREMAR Institute were examined. Turtles were placed in the dorsal decubitus position during US examination, which did not require anesthesia. Even though the plastron is constituted of bones and cartilage, the present research has proven the viability of obtaining US images through it, making it possible to visualize structures undetectable through the acoustic windows previously suggested. The following organs were evaluated through the plastron: heart, stomach, duodenum, jejunum, colon, liver, gallbladder, kidneys, bladder, and spleen (in case of splenomegaly). US imaging through the plastron is a viable approach for detecting ingested artificial debris, which represents one of the leading causes of death among sea turtles.

Retención de cápsula endoscópica en enfermedad de Crohn ¿cómo manejarla? / Retained capsule endoscopy in Crohn´s disease: how to manage it?

Capsule endoscopy is a technique that allows the study of the small intestine, through a device that is swallowed by the patient, capturing images as it travels through the digestive tract. Capsule retention is the most serious complication. We report the case of a 69 year-old male presenting with iron deficiency anemia, with normal upper endoscopy and colonoscopy; but obscure gastrointestinal bleeding was diagnosed and therefore a study with capsule endoscopy was requested. The patient evolves with retained capsule in the small intestine with ulcerated stenosis as shown by imaging. This finding was confirmed by enteroscopy with biopsy, without being able to extract the capsule. Medical management with corticosteroids was indicated for intestinal obstruction secondary to inflammatory stenosis in the context of Crohn's disease: The capsule was expelled after 21 days of ingestion, with a positive outcome

La cápsula endoscópica es una técnica que permite el estudio del intestino delgado, mediante un dispositivo que es deglutido por el paciente y captura imágenes en su recorrido por el tubo digestivo. La complicación más grave es la retención de la cápsula. Se reporta el caso de un paciente de sexo masculino, de 69 años con anemia ferropénica, con endoscopia alta y colonoscopia normal; planteándose sangrado gastrointestinal de origen oscuro por lo que se solicita estudio con cápsula endoscópica. El paciente evoluciona con retención de la cápsula en intestino delgado, visualizándose en las imágenes la presencia de estenosis ulcerada, hallazgo que se confirma mediante enteroscopia con toma de biopsias, sin lograr extraer la cápsula. Se indica manejo médico con corticoides por obstrucción intestinal secundario a estenosis inflamatoria en contexto de enfermedad de Crohn, expulsando espontáneamente la cápsula al día 21 de su ingestión, sin complicaciones.

Foreign body impaction in the esophagus: are there underlying motor disorders?

RESULTS: Compared with the control group, the impacted subjects presented marked reduction in amplitude and duration of esophageal contraction in the proximal esophagus. CONCLUSIONS: These motor disorders could be responsible for the foreign body impaction in the esophagus. However, we believe this patient group should be further studied by 24-hour esophageal manometry to reach a more accurate diagnosis by studying each patient's entire circadian cycle.

Unintentionally retained foreign bodies after surgical procedures. Analysis of 4547 cases.

OBJECTIVE: this study aims to explore the experience of Brazilian surgeons on Unintentionally Retained Foreign Bodies (RFB) after surgical procedures. METHODS: A questionnaire was sent to surgeons by electronic mail, between March and July 2012. The questions analyzed their experience with foreign bodies (FB), foreign bodies' types, clinical manifestations, diagnoses, risk factors and legal implications. RESULTS: in the 2872 eligible questionnaires, 43% of the surgeons asserted that they had already left FB and 73% had removed FB in one or more occasions, totalizing 4547. Of these foreign bodies, 90% were textiles, 78% were discovered in the first year and 14% remained asymptomatic. Among doctors with less than five years after graduation, 36% had already left a FB. The most frequently surgical procedures mentioned were the elective (57%) and routine (85%) ones. Emergency (26%), lack of counting (25%) and inadequate conditions of work contributed (12.5%) to the occurrence. In 46% of the cases patients were alerted about the FB, and 26% of them sued the doctors or the institution. CONCLUSIONS: challenging medical situations, omission of security protocols and inadequate work conditions contributed to RFB. However, RFB occurs mostly in routine procedures such as cesarean or cholecystectomy, and at the beginning of the professional career, highlighting, particularly in poorest countries, the need for primary prevention. Textiles predominated causing clinical repercussions and they were diagnosed in the first postoperative months. Surgeons were sued in 11.3% of the RFB cases.

Objetivo: avaliar a experiência de cirurgiões brasileiros com a retenção inadvertida de corpos estranhos (RICE) após procedimentos cirúrgicos. Métodos : foi enviado por correio eletrônico um questionário para cirurgiões, de março a julho de 2012. As questões avaliavam a sua experiência com RICE, os tipos de corpos estranhos, suas manifestações clínicas, diagnósticos, fatores de risco e implicações jurídicas. Resultados : 2872 questionários foram analisados. Destes, 43% dos cirurgiões já teriam deixado algum corpo estranho (CE) e 73% removido um CE em uma ou mais ocasiões. De um total de 4547 CE, 90% eram têxteis, 78% foram descobertos dentro do primeiro ano, e 14% assintomáticos. No grupo dos médicos graduados há menos de cinco anos, 36% já havia deixado um CE. Os procedimentos operatórios mais relacionados eram eletivos (54%) e rotineiros (85%). Emergência (26%), ausência de contagem (25%) e condições inadequadas de trabalho também contribuíram com a ocorrência (12,5%). Em 46% dos casos os pacientes tomaram ciência da retenção e 26% deles processaram os médicos ou as instituições. Conclusão: s ituações médicas desafiadoras, omissão de protocolos de segurança e condições inadequadas de trabalho contribuíram com a RICE. Entretanto, as RICE ocorreram principalmente em operações de rotina, como cesarianas e colecistectomias, principalmente no início da carreira profissional, ressaltando, principalmente em países mais pobres, a necessidade de prevenção primária. Os têxteis predominaram, acarretando repercussões clínicas e sendo diagnosticados nos primeiros meses de pós-operatório. Os médicos foram processados em 11,3% dos casos de RICE.

Cuerpo extraño en la vía aérea en pediatría / Foreign-body aspiration in children

It is a frequent pediatric event and a common cause of morbidity and mortality in children, requiring accurate diagnosis and proper treatment. Diagnosis is usually based on clinical manifestations such as cough, dyspnea. stridor, respiratory distress and asymmetric decreased air entry or unilateral wheeze. Choking crisis may be absent or minimized. Chest X-ray may have no abnormalities or show signs such as asymmetrical hyperinflation, massive, fixed or changing atelectasis. Occasionally, hyperinflation or obstructive emphysema with atelectasis can be present in the same hemithorax. Inspiratory and expiratory chest X-rays show ipsilateral mediastinum movements. Most foreign bodies are not visible to chest X-ray exploration. Acute suffocation must be treated with Heimlich procedure. In later stages, diagnosis and treatment require rigid bronchoscopy. Prognosis is fairly positive with an early and complete foreign-body extraction.

La aspiración de un cuerpo extraño (CE) a la vía aérea en pediatría es un accidente frecuente, presenta importante morbimortalidad, por lo que requiere un diagnóstico y tratamiento oportuno. El diagnóstico usualmente se establece mediante hallazgos clínicos, siendo los más frecuentes tos, síndrome de penetración, y con menor frecuencia dificultad respiratoria, estridor, sibilancias unilaterales. La radiografía de tórax puede ser normal o alterada, mostrando hiperinsuflación unilateral, atelectasia u otros signos. La mayoría de los CE son radiotransparentes. Durante la fase aguda debe practicarse la maniobra de Heimlich, en cambio en la fase crónica el diagnóstico y tratamiento definitivo se hace mediante broncoscopía. La prevención es fundamental evitando que niños menores manipulen objetos pequeños, advertir el riesgo de asfixia por aspiración en los envases de alimentos riesgosos y de juguetes de pequeño tamaño. El pronóstico es bueno si la extracción del cuerpo extraño es precoz y completa.

Intrathoracic gossypiboma presenting 52 years later as a chest mass.

We describe the rare case of a 71-year-old man with a chest mass that was found to be an intrathoracic gossypiboma left 52 years earlier during an emergency lung bilobectomy. This mass was complicated by extension across the chest wall. There are no reports in the literature of a patient carrying a thoracic gossypiboma for such a long period of time, let alone with extension across the chest wall.
