ABSTRACT

Necrotizing fasciitis (NF) is a potentially life-threatening surgical emergency. It is a rapidly progressive infection of soft tissues, and mortality is related to the degree of sepsis and the general condition of the patient. It is a rare condition that requires a rapid diagnosis and surgical treatment is aggressive debridement. There are a small number of reported cases of perforation of a rectal malignancy leading to NF of the thigh. We present a case with rectal cancer in which the sciatic foramen had provided a channel for the spread of pelvic infection into the thigh.


La fascitis necrotizante es una emergencia quirúrgica potencialmente mortal. Es una infección de tejidos blandos rápidamente progresiva y la mortalidad está relacionada con el grado de sepsis y el estado general del paciente. Es una condición poco común que requiere un diagnóstico rápido, y el tratamiento quirúrgico consiste en un desbridamiento agresivo. Existe un pequeño número de casos notificados de perforación de neoplasia maligna de recto que conduce a fascitis necrotizante del muslo. Presentamos un caso de cáncer de recto en el cual el foramen ciático fue el canal para la propagación de la infección pélvica al muslo.

ABSTRACT

INTRODUCTION: Necrotizing soft tissue infections (NSTI) are increasing, posing a significant risk of morbidity and mortality. Due to nonspecific symptoms, a high index of suspicion is crucial. Treatment involves a multidisciplinary approach, with broad-spectrum antibiotics, early surgical debridement, and life support. This study analyzes the characteristics, demographics, complications, and treatment of NSTI in a hospital in Madrid, Spain. METHODS: A retrospective observational study was conducted, including all surgically treated NSTI patients at our center from January 2016 to December 2022, examining epidemiological and clinical data. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) was prospectively calculated for all patients. RESULTS: Twenty-two patients (16 men, 6 women, mean age 54.8) were included. Median time from symptom onset to emergency room visit was 3.5 days. All reported severe treatment-resistant pain; sixteen had fever exceeding 37.8°C (72.7%). Skin lesions occurred in twelve (54.5%), and thirteen had hypotension and tachycardia (59.1%). Treatment involved resuscitative support, antibiotherapy, and radical debridement. Median time to surgery was 8.25h. Intraoperative cultures were positive in twenty patients: twelve Streptococcus pyogenes, four Staphylococcus aureus, one Escherichia coli, and four polymicrobial infection. In-hospital mortality rate was 22.73%. CONCLUSIONS: We examined the correlation between our results, amputation rates and mortality with LRINEC score and time to surgery. However, we found no significant relationship unlike some other studies. Nevertheless, a multidisciplinary approach with radical debridement and antibiotic therapy remains the treatment cornerstone. Our hospital stays, outcomes and mortality rates align with our literature review, confirming high morbimortality despite early and appropriate intervention.

ABSTRACT

Introducción: La enterocolitis necrotizante (ECN) es una enfermedad potencialmente mortal que afecta a los neonatos, y frente a laque la leche materna ha demostrado tener un papel protector. Administrando lipopolisacáridos (LPS) por vía oral en ratas recién nacidas(RRN), hemos desarrollado un modelo experimental para inducir undaño intestinal similar al que provoca la ECN con objeto de evaluarel aspecto macroscópico y microscópico del intestino, y de ese modo,analizar la presencia de ECN y estudiar el papel que desempeña laleche materna (LM). Material y métodos: Las RRN se dividieron en tres grupos: el grupoA (control, n= 10) permaneció con su madre; el grupo B (LPS, n=25)fue aislado tras el nacimiento, alimentado por sonda con una fórmulaespecial para ratas y LPS oral, y sometido a estrés (hipoxia tras sonda);y el grupo C (LM, n= 12) fue alimentado con leche materna tras elnacimiento y posteriormente aislado y sometido a estrés al igual que elgrupo B. El día 4 se sacrificó a las RRN y se recuperaron sus intestinospara su posterior evaluación. Resultados: En el grupo de control, no se observó ECN ni macroscópica ni histológicamente, mientras que los dos grupos sometidos aestrés (B y C) presentaron una incidencia global de la ECN del 73%.La mayoría de los sujetos del grupo B desarrollaron signos histológi-cos de ECN (85%), y los del grupo C registraron una incidencia de laECN estadísticamente menor (50%, p= 0,04), lo que significa que laLM desempeña una función protectora frente a la ECN (OR= 0,19; IC95%: 0,40-0,904). Conclusión: Nuestro modelo reveló una incidencia significativa dela ECN en RRN (73%), desempeñando la LM la misma función protectora que en el caso de los humanos recién nacidos, lo que significa que estemodelo experimental de ECN es fiable y reproducible. Gracias a dichologro, podremos investigar nuevos y potenciales objetivos terapéuticospara una peligrosa enfermedad que, a día de hoy, carece de tratamiento.(AU)


Introduction: Necrotizing enterocolitis (NEC) is a life-threateningcondition that afflicts neonates. Breastfeeding has demonstrated to playa protective role against it. By administering lipopolysaccharides (LPS)orally in newborn rats (NBR), we have developed an experimental modelto induce NEC-like gut damage. Our aim was to assess the macroscopicand microscopic appearance of the gut, to evaluate the presence of NECand study the role of breast milk (BM). Material and methods: NBR were divided into 3 groups: GroupA (control, n= 10) remained with the mother, group B (LPS, n= 25)was isolated after birth, gavage-fed with special rat formula and oralLPS, then submitted to stress (hypoxia after gavage) and group c (BM,n= 12) was breastfed once after birth, then isolated, and submitted tostress like group B. On day 4, NBR were sacrificed, and intestine washarvested and assessed. Results: In the control group NEC was not present either macroscopically or histologically. Both groups submitted to stress (B and C)presented a global incidence of NEC of 73%. Most of group B developedhistologic signs of NEC (85%) and group C showed a statistically lowerincidence of NEC (50%, p= 0.04), playing the BM a protective roleagainst NEC (OR= 0.19; 95% CI: 0.40- 0.904)Conclusion: Our model showed a significant incidence of NEC inNBR (73%) with the same protective role of BM as in newborn humans,achieving a reliable and reproducible experimental NEC model. This willallow us to investigate new potential therapeutic targets for a devastatingdisease that currently lacks treatment.(AU)

ABSTRACT

Subsequent to mass vaccination programs against COVID-19, diverse side effects have been described, both at the injection site, such as pain, redness and swelling, and systemic effects such as fatigue, headache, muscle or joint pain. On rare occasions, a lymphadenopathic syndrome may develop, raising the clinical suspicion of a lymphoproliferative disorder. We present the case of a 30-year-old woman who developed self-limiting left axillary lymphadenopathy following COVID-19 vaccination. To date, only seven similar cases with a complete clinicopathological description have been published, and fourteen cases have been notified to the European adverse events databases (Eudravigilance) in relationship with vaccination against COVID-19. It is important to be aware of this potential complication when a lymphadenopathic syndrome develops following vaccination, to avoid unnecessary treatment. (AU)


Tras la vacunación masiva frente a la COVID-19 se han comenzado a describir diversos efectos adversos incluyendo efectos locales en el lugar de la inyección, como dolor, enrojecimiento, hinchazón, etc., y efectos sistémicos como fatiga, dolor de cabeza, dolor muscular o articular. Más infrecuentemente se pueden desarrollar cuadros linfadenopáticos sospechosos clínicamente de proceso linfoproliferativo. Presentamos el caso de una mujer de 30 años que desarrolló linfadenopatía axilar izquierda tras la vacunación contra la COVID-19 con hallazgos histopatológicos de linfadenopatía necrotizante de tipo Kikuchi y resolución espontánea. Hasta el momento se han publicado 7 casos con descripción clinicopatológica completa en la literatura y notificado 14 casos en la Red Europea de Farmacovigilancia en relación con la vacunación. Es importante tener en cuenta esta entidad en linfadenopatías sospechosas de procesos linfoproliferativos en este contexto, para evitar un tratamiento innecesario. (AU)

ABSTRACT

Introdução:A enterocolite necrosante é uma doença que pode afetar o trato gastrointestinal de recém-nascidos,cujas manifestações clínicas podem ser caracterizadas por vômitos biliosos, sangue nas fezes, distensão abdominal, além de alterações nos parâmetros hemodinâmicos e instabilidade térmica. As populações mais vulneráveis a essa enfermidade são recém-nascidos de baixo peso,expostos ao ambiente de terapia intensiva neonatal. Objetivos: Identificar o perfil de recém-nascidos e os fatores maternos e neonatais associados à ocorrência de óbitos por enterocolite necrosante, em maternidade de referência do Ceará-Brasil. Metodologia: Trata-se de coorte retrospectiva, estudo que objetiva a descrição da incidência de determinado evento ao longo do tempo, além do estabelecimento de relações causais entre os fatores associados ao acontecimento. Incluíram-serecém-nascidos que tiveram óbitos por enterocolite necrosante entre 2019 e 2021, comficha de investigação de óbitos neonatais preenchida corretamente, não sendo excluído nenhum recém-nascido, totalizando amostra de 29 óbitos.Resultados: Identificou-se que o perfil dos recém-nascidos foi,em maioria, deprematuros e com baixo peso e fatores de risco para outras doenças associadas,como a sepse, o que acarretourealização de procedimentos invasivos e internação em ambiente de terapia intensiva neonatal.Conclusões: A prematuridade e o baixo peso ao nascer foram as variáveis relevantes no estudo e podem estar associadas à piora das condições clínicas do recém-nascido e ao desenvolvimento de enterocolite necrosante (AU).


Introduction: Necrotizing Enterocolitis is a disease that can affect the gastrointestinal tract of newborns, whose clinical manifestations can be characterized by bilious vomiting, blood in stool, abdominal distension, in addition to changes in hemodynamic parameters and thermal instability. The populations most vulnerable to this disease are low birth weight newborns exposed to the neonatal intensive care environment. Objectives: This study aimed to identify the profile of newborns and maternal and neonatal factors associated with the occurrence of deaths from necrotizing enterocolitis in a reference maternity hospital in Ceará, Brazil. Methodology: This is a retrospective cohort study seeking to describe the incidence ofa particular event over time, as well as establish causal relationships between the factors associated with the event. The study population comprised newborns who died from necrotizing enterocolitis between 2019 and 2021, who had neonatal death investigation forms filled out correctly, with no newborns being excluded, totaling a sample of 29 deaths. Results: It was identified that the profile of newborns was mostly premature, of low birth weight and with risk factors for other associated diseases such as sepsis, leading to invasive procedures and hospitalization in a neonatal intensive care environment. Conclusions: Prematurity and low birth weight were relevant variables in the study and may be associated with worsening of the newborn's clinical conditionsand development of necrotizing enterocolitis (AU).

ABSTRACT

Introducción: La fascitis necrotizante es un cuadro muy grave causado por una infección bacteriana de la piel y de tejidos blandos subcutáneos, cuya evolución es hacia la destrucción y necrosis de los tejidos en un corto espacio de tiempo; el lupus eritematoso sistémico es una enfermedad autoinmune de causa desconocida que quienes la padecen tienen una mayor probabilidad de contraer infecciones debido al mal funcionamiento del sistema inmunológico y/o los efectos secundarios causados por los medicamentos. Objetivo: Observar la importancia de un tratamiento rápido y eficaz de la fascitis necrotizante en un paciente con lupus eritematoso sistémico y esteatohepatitis no alcohólica. Presentación de caso: Se presentó el caso clínico de un paciente de 30 años con diagnóstico de lupus eritematoso sistémico que desarrolló de forma concomitante de fascitis necrotizante y esteatohepatitis no alcohólica. A pesar de un tratamiento adecuado, el paciente fue agresivo. Tuvo una estadía hospitalaria de 83 días, con una evolución desfavorable que conllevó a la muerte(AU)


Introduction: Necrotizing fasciitis is a very serious condition caused by a bacterial infection of the skin and subcutaneous soft tissues, whose evolution is towards the destruction and necrosis of the tissues in a short space of time; Systemic lupus erythematosus is an autoimmune disease of unknown cause that sufferers are more likely to contract infections due to poor immune system function and/or side effects caused by medications. Objective: To observe the importance of rapid and effective treatment of necrotizing fasciitis in a patient with systemic lupus erythematosus and non-alcoholic steatohepatitis. Case report: We report the clinical case of a 30-year-old patient diagnosed with systemic lupus erythematosus who concomitantly developed necrotizing fasciitis and nonalcoholic steatohepatitis. Despite adequate treatment, the patient was aggressive. The patient had a hospital stay of 83 days, with an unfavorable evolution that led to his death(AU)

ABSTRACT

Producto de una pancreatitis aguda (PA) puede haber una diabetes posterior o una hiperglicemia transitoria durante el episodio de PA. La incidencia de PA en edad pediátrica es de hasta 12,2 casos por 100 000 niños al año y sólo el 4 a 5% desarrollan luego diabetes. Con respecto a la hiperglicemia transitoria en niños, la información es escasa y no se ha hecho publicaciones al respecto en nuestro país. Se reporta el caso de una niña con hiperglicemia transitoria secundaria a una PA necrotizante grave. Es importante realizar un monitoreo constante de los niveles de glucosa y el tratamiento oportuno de la hiperglicemia en niños con PA ya que, al menos en adultos, se asocia a PA severa y mayor mortalidad.


As a result of acute pancreatitis (AP), there may be subsequent diabetes or transient hyperglycemia during the episode of AP. The incidence of AP in pediatric age is up to 12.2 cases per 100,000 children per year and only 4 to 5% later develop diabetes. Regarding transient hyperglycemia in children, information is scarce, and no publications have been made about it in our country. The case of a girl with transient hyperglycemia secondary to severe necrotizing AP is reported. It is important to constantly monitor glucose levels and timely manage hyperglycemia in children with AP since, at least in adults, it is associated with severe AP and higher mortality.

ABSTRACT

BACKGROUND: Immune checkpoint inhibitors (ICIs) are a promising new treatment for different types of cancer. The infectious complications in patients taking ICIs are rare. CASE REPORT: A 58-year-old male who received chemotherapy consisting of pembrolizumab (PD-1 inhibitor) for esophagus squamous cell carcinoma one month before was admitted to the emergency room with shortness of breath soon after fiberoptic bronchoscopy, which was done for the inspection of the lower airway. A computed tomography of the chest revealed a progressive consolidation on the right upper lobe. Salmonella group D was isolated from the bronchoalveolar lavage (BAL) fluid culture. The fungal culture of the same clinical sample yielded Aspergillus niger; furthermore, a high titer (above the cut-off values) of Aspergillus antigen was found both in the BAL fluid and serum of the patient. Despite the effective spectrum and appropriate dose of antimicrobial treatment, the patient died due to disseminated intravascular coagulopathy. CONCLUSIONS: Awareness of unusual pathogens in the etiology of pneumonia after ICI treatment may help to avoid underdiagnosis.

ABSTRACT

INTRODUCTION: In 2016, a protocol was developed in our hospital for the antenatal administration of magnesium sulfate in pregnant women at risk of imminent preterm birth as a method to reduce the risk of cerebral palsy (CP). MATERIAL AND METHODS: We conducted a retrospective observational study in a level IIIC hospital with the primary objective of comparing the incidence of CP before and after the implementation of this protocol. Among the secondary outcomes, we ought to highlight the incidence of cognitive deficits and necrotizing enterocolitis and the mortality in both groups. The sample consisted of preterm newborns delivered before 32 weeks of gestation in 2011-2012 (prior to the implementation of the protocol) and in 2016-2018 (after the implementation of the protocol, whose mothers had received magnesium sulfate for neuroprotection). The clinical and epidemiological characteristics of both groups were comparable. RESULTS: We collected data for a total of 523 patients, 263 and 260 in each group. As regards the primary outcome, we did not find statistically significant differences between groups. We observed a statistically significant reduction in mortality and the risk of severe necrotizing enterocolitis in the group of patients born in the 2016-2018 period and between 26+0 and 27+6 weeks of gestation, whose mothers had received magnesium sulfate. CONCLUSIONS: In our study, the administration of magnesium sulfate to mothers at risk of preterm birth did not decrease the risk of developing CP.

Antecedentes: Los fármacos inhibidores de puntos de control inmunitario (ICI) son una nueva y prometedora opción de tratamiento para diferentes tipos de cáncer. Las complicaciones infecciosas en pacientes que toman ICI son poco frecuentes. Caso clínico: Un varón de 58 años que recibió quimioterapia con pembrolizumab (inhibidor de PD-1) para un carcinoma de células escamosas de esófago hacía un año, ingresó en Urgencias por dificultad respiratoria poco después de realizarse una broncoscopia de fibra óptica para una inspección de las vías aéreas inferiores. La tomografía computarizada de tórax reveló una consolidación progresiva en el lóbulo superior derecho. Se aisló Salmonella grupo D en el cultivo del líquido de lavado broncoalveolar (LBA). En el cultivo de hongos de la misma muestra creció Aspergillus niger; además, se detectó antígeno (por encima de los valores de corte) de Aspergillus tanto en la muestra del LBA como en el suero del paciente. A pesar del espectro eficaz y la dosis adecuada del antifúngico utilizado, el paciente falleció debido a una coagulopatía intravascular diseminada. Conclusiones: El conocimiento de patógenos inusuales en la etiología de la neumonía tras el tratamiento con ICI puede ayudar a evitar el infradiagnóstico.(AU)

ABSTRACT

RESUMEN La agranulocitosis es el recuento bajo de glóbulos blancos (neutrófilos), que puede ser inducida por tratamientos con algunos medicamentos como los antitiroideos, que ocasionan manifestaciones orales como úlceras o necrosis gingival difusa. Se presenta el caso de una paciente mujer de 26 años, con antecedente de hipertiroidismo, quien acude a emergencia del Hospital Nacional Alberto Sabogal Sologuren por presentar tumefacción en la hemicara izquierda, asociada a disfagia, múltiples lesiones ulceradas en mucosa oral, con compromiso de tejido óseo, fiebre y malestar general. Luego de los exámenes auxiliares, se categoriza como una infección oral y cervicofacial por agranulocitosis debido al tratamiento con el metimazol. La literatura mundial reporta casos de agranulocitosis como efecto adverso del consumo de drogas antitiroideas, con reporte de manifestaciones orales; sin embargo, pocos casos evidencian compromiso cervical. Por lo cual se presenta este caso poco usual desde su diagnóstico hasta el tratamiento.


ABSTRACT Agranulocytosis refers to a low white blood cell count, specifically neutrophils, which can be caused by certain medications such as antithyroid drugs (ATD). This condition can result in oral manifestations, including diffuse gingival ulceration or necrosis. We present the case of a 26-year-old female patient with a history of hyperthyroidism who came to the emergency department of Alberto Sabogal Sologuren National Hospital with swelling on the left side of her face, accompanied by dysphagia, multiple ulcerated lesions in the oral mucosa involving bone tissue, as well as fever and general malaise. After conducting additional tests, the patient was diagnosed with oral and cervicofacial infection secondary to agranulocytosis caused by methimazole treatment. While the global literature reports cases of agranulocytosis as an adverse effect of antithyroid medication, with documented oral manifestations, only a few cases demonstrate cervical involvement. Therefore, we present this uncommon case from diagnosis to treatment.

ABSTRACT

Introduction: SARS-CoV-2 infection generates a higher risk of complications and mortality in previously ill patients, patients with diabetes mellitus have a weaker immune system and the increase in blood glucose can compromise innate immunity and humoral immunity. Therefore, these patients are more susceptible to soft tissue infections. Objective: To describe the evolution and complications of a patient with type II diabetes mellitus with SARS-CoV-2 infection who presented necrotizing fasciitis on the 15th day of disease evolution. Case presentation: A 52-year-old male patient, white, with type II diabetes mellitus and high blood pressure for which he was treated with slow insulin, metformin, enalapril, and hydrochlorothiazide, was admitted as a positive case of COVID-19, at Fifteenth day of stay began with fever, heat and flushing, swelling beyond the area of erythema and crepitus in both lower limbs, surgical intervention was decided. In the operating room, drainage, debridement, and necrectomy were performed on both lower limbs. Microbiological analysis through culture detected the growth of Pantoea agglomerans . Conclusions: Diabetes mellitus, the use of glucocorticoids, were the risk factors found to cause the state of immunosuppression in the case presented, and the use of biological anti-TNF drugs (Nimotuzumab). It is necessary to be insistent on prevention measures: maximum asepsis in the handling of intravenous access, and judicious use of antibiotics.


Introducción: La infección por SARS-CoV-2 genera un mayor riesgo de complicaciones y mortalidad en pacientes previamente enfermos, los pacientes con diabetes mellitus tienen un sistema inmunológico más débil y el aumento de glucosa en sangre puede comprometer la inmunidad innata y la inmunidad humoral, por lo que estos pacientes son más susceptibles a sufrir infecciones de partes blandas. Objetivo: Describir la evolución y complicaciones de un paciente portador de diabetes mellitus tipo II con infección por SARS-CoV-2 que presentó una fascitis necrotizante al 15to día de evolución de la enfermedad. Presentación de caso: Paciente de 52 años de edad, sexo masculino, blanco, portador de diabetes mellitus tipo II e hipertensión arterial para lo cual llevó tratamiento con insulina lenta, metformina, enalapril e hidroclorotiazida, ingresó como caso positivo de COVID-19, al décimo quinto día de estadía comenzó con fiebre, calor y rubor, tumefacción más allá del área de eritema y crepitación en ambos miembros inferiores, se decidió intervención quirúrgica. En el salón de operaciones se realizó drenaje, desbridamiento y necrectomía en ambos miembros inferiores, el análisis microbiológico a través de cultivo detectó el crecimiento de Pantoea Agglomerans. Conclusiones: La diabetes mellitus, el uso de glucocorticoides, fueron los factores de riesgo encontrados como causantes del estado de inmunodepresión en el caso presentado, y el uso de medicamentos biológicos anti-TNF (Nimotuzumab). Es necesario ser insistente en las medidas de prevención: la máxima asepsia en la manipulación de accesos intravenosos, y el uso juicioso de antibióticos.


Introdução: A infecção por SARS-CoV-2 gera maior risco de complicações e mortalidade em pacientes previamente enfermos, pacientes com diabetes mellitus têm sistema imunológico mais fraco e o aumento da glicemia pode comprometer a imunidade inata e a imunidade humoral. suscetível a infecções de tecidos moles. Objetivo: Descrever a evolução e complicações de um paciente com diabetes mellitus tipo II com infecção por SARS-CoV-2 que apresentou fasceíte necrosante no 15º dia de evolução da doença. Apresentação do caso: Paciente do sexo masculino, 52 anos, branco, com diabetes mellitus tipo II e hipertensão arterial, para o qual fazia tratamento com insulina lenta, metformina, enalapril e hidroclorotiazida, foi admitido como caso positivo de COVID-19, No décimo quinto dia de internação, ela começou com febre, calor e rubor, inchaço além da área de eritema e crepitação em ambos os membros inferiores, sendo decidida a cirurgia. Na sala cirúrgica foi realizada drenagem, desbridamento e necrectomia em ambos os membros inferiores, a análise microbiológica por meio de cultura detectou o crescimento de Pantoea Aglomerans. Conclusões: Diabetes mellitus, uso de glicocorticóides foram os fatores de risco encontrados para causar o estado de imunossupressão no caso apresentado e uso de drogas biológicas anti-TNF (Nimotuzumab). É preciso insistir nas medidas preventivas: a máxima assepsia no manuseio dos acessos intravenosos e o uso criterioso de antibióticos.

ABSTRACT

Introducción: Las estatinas son de los medicamentos más recetados. Aunque las estatinas generalmente se toleran bien, pueden provocar efectos secundarios musculoesqueléticos. La miopatía autoinmune necrotizante inducida por estatinas (SINAM) es una afección rara y la prevalencia sólo es de 1 de cada 100.000 personas. Este trastorno se caracteriza por debilidad muscular simétrica progresiva y grave, elevación marcada de la creatincinasa y síntomas persistentes a pesar de la interrupción de la estatina. La electromiografía suele mostrar un patrón de miopatía irritable inespecífico, indistinguible de otras miopatías inflamatorias. La biopsia muscular muestra la presencia de fibras necróticas, fibras en regeneración sin células inflamatorias significativas y una regulación positiva difusa o focal de la expresión del complejo mayor de histocompatibilidad de clase I. Los anticuerpos anti-3-hidroxi-3-metilglutaril-coenzima A (anti-HMG-CoA) reductasa representan un rasgo serológico característico de la SINAM.Caso clínico: Presentamos a un paciente que desarrolló debilidad muscular progresiva después de tomar simvastatina durante los últimos siete años. En la presentación inicial, su nivel de creatincinasa fue de 2.954 U/L y los anticuerpos anti-HMG-CoA reductasa fueron positivos. La biopsia mostró rasgos miopáticos profundos con numerosas fibras necróticas, algunas fibras en regeneración e infiltrado de células inflamatorias perimisial, combinado con una sobreexpresión difusa del complejo mayor de histocompatibilidad de clase I. Se le diagnosticó SINAM, se suspendió la estatina y se inició una dosis alta de corticoides sistémicos, inmunoglobulina intravenosa y metotrexato. Después de tres meses de seguimiento, tuvo una mejora significativa en la fuerza muscular y el nivel de creatincinasa volvió a la normalidad.(AU)


Introduction: Statins are some of the most widely prescribed medications. Although statins are generally well tolerated, they can lead to musculoskeletal side effects. Statin-induced necrotizing autoimmune myositis (SINAM) is a rare condition and the prevalence is only 1 per 100,000 people. This disorder is characterized by progressive and severe symmetric muscle weakness, marked elevation of creatine kinase and persistent symptoms despite statin discontinuation. Electromyography commonly shows a nonspecific irritable myopathy pattern indistinguishable from other inflammatory myopathies. Muscle biopsy shows the presence of necrotic fibers, regenerating fibers without significant inflammatory cells and diffuse or focal upregulation of major histocompatibility complex class I expression. The anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibodies represent a characteristic serological feature of SINAM. Case report: We present a patient who developed progressive muscle weakness after taking simvastatin for the last seven years. At initial presentation, her creatine kinase level was 2,954 U/L and anti-HMGCR antibodies were positive. The biopsy showed a profound myopathic features with numerous necrotic fibers, some regenerating fibers and perimysial inflammatory cell infiltrate, combined with a diffuse overexpression of major histocompatibility complex class I products. She was diagnosed with SINAM, statin was suspended and a high dose of systemic corticosteroids, intravenous immunoglobulin therapy and methotrexate was started. At three-month follow-up, she had significant improvement in muscle strength and creatine kinase level returned to normal...(AU)

ABSTRACT

Introducción: La fascitis necrotizante es una infección grave que involucra la piel, el tejido celular subcutáneo y las fascias superficiales-profundas, progresa muy rápidamente y si no se trata a tiempo puede causar la muerte. Reporte de caso: Presentamos el caso de una paciente adulta con antecedentes de anemia, a quien se le diagnosticó fascitis necrosante de origen odontogénico, por lo que fue intervenida quirúrgicamente y se realizó un drenaje intraoral y extraoral más escarectomía. Además, se le administró tratamiento farmacológico (antibióticos intravenosos) y se colocó una membrana amniótica como material de apósito para reconstruir la superficie hemorrágica dejada por la fascitis necrotizante. Conclusiones: La membrana amniótica como material de apósito presentó resultados favorables en la paciente al obtenerse una rápida regeneración de la secuela producida por la fascitis necrotizante.


Introduction: Necrotizing fasciitis is a serious infection that involves the skin, the subcutaneous tissue, and the superficial-deep fascia, it progresses very quickly and if not treated in time it can cause death. Report case: We present the case of an adult patient with a history of anemia, who was diagnosed with odontogenic necrotizing fasciitis, for which she underwent surgery and underwent intraoral and extraoral drainage plus escharectomy. In addition, pharmacological treatment (intravenous antibiotics) was administered, and an amniotic membrane was placed as a dressing material to reconstruct the hemorrhagic surface left by the necrotizing fasciitis. Conclusions: The amniotic membrane as a dressing material presented favorable results in the patient, obtaining a rapid regeneration of the sequel produced by necrotizing fasciitis.

ABSTRACT

La sialometaplasia necrotizante es una entidad patológica benigna y autolimitante que se presenta en glándulas salivales menores, ubicada con mayor frecuencia en el límite entre el paladar duro y blando. Presenta una etiología poco clara, asociándose a trauma físico, químico o biológico, que produciría necrosis por isquemia del tejido glandular y un posterior intento de reparación, que histológicamente se traduce en una metaplasia del tejido. Clínicamente puede presentarse como una úlcera irregular, de bordes solevantados y fondo necrótico, confiriéndole un aspecto fácilmente confundible con una neoplasia maligna oral. Si bien presentan una baja prevalencia, su conocimiento puede evitar maniobras clínicas innecesarias y mutilantes. Se presenta el caso de un adulto, quien contaba con antecedentes familiares de neoplasia maligna de cabeza y cuello, y su evolución clínica. Lesiones ulceradas de aspecto crateriforme, ubicadas en el paladar, deberían evocar a esta lesión como parte de sus hipótesis diagnósticas, su conocimiento puede evitar llevar a cabo tratamientos mutilantes e innecesarios.


A sialometaplasia necrosante é uma entidade patológica benigna e autolimitada que ocorre nas glândulas salivares menores, mais frequentemente localizadas na margem do palato duro e mole. Tem etiologia incerta, estando associada a uma lesão física, química ou biológica, que produziria necrose por isquemia do tecido glandular e posteriormente uma tentativa de reparação, que se traduz histologicamente em metaplasia tecidual. Clinicamente, pode apresentar-se como uma úlcera irregular, com bordas elevadas e base necrótica, o que lhe confere um aspecto facilmente confuso com uma neoplasia oral maligna. Embora tenham baixa prevalência, seu conhecimento pode evitar intervenções clínicas desnecessárias. Apresentamos o caso de um adulto, com histórico familiar de neoplasia maligna de cabeça e pescoço, e sua evolução clínica. Aspectos relevantes são discutidos. Lesões ulceradas com aspecto de cratera, localizadas no palato, devem evocar essa lesão como parte de suas hipóteses diagnósticas, seu conhecimento pode evitar a realização de tratamentos mutilantes e desnecessários. necrotizing sialometaplasia, minor salivary glands; mouth neoplasms.

ABSTRACT

Introducción y objetivo: La otitis externa maligna (OEM) es una infección agresiva de los tejidos blandos del oído externo y estructuras circundantes, que puede diseminarse e involucrar la base del cráneo y la articulación temporomandibular (ATM). Afecta fundamentalmente a pacientes inmunodeprimidos mayores de 65 años. El objetivo de este trabajo ha sido conocer las características de los pacientes diagnosticados de OEM en nuestro hospital durante los últimos años y establecer los criterios diagnóstico-terapéuticos de esta rara enfermedad. Método: Se realizó un estudio descriptivo, observacional y retrospectivo, de los pacientes ingresados en el Hospital Clínico Universitario de Valladolid por OEM entre los años 1996 y 2021. Resultados: En los últimos 25 años fueron ingresados por OEM nueve pacientes, 78% varones (7/9) y con una edad media de 76,8 años. Todos manifestaron precozmente la enfermedad, con otalgia, otorrea y tejido de granulación en el conducto auditivo externo (CAE). Ninguno tuvo afectación de pares craneales, pero cuatro sufrieron invasión de la ATM y dos fallecieron. Discusión y Conclusiones: Actualmente el diagnóstico de OEM se establece a partir de una variedad de hallazgos clínicos, de laboratorio y radiográficos. El tratamiento antibiótico depende de la severidad de la infección. Desde la aparición de los antibióticos antipseudomónicos, el tratamiento quirúrgico inicial de esta patología no está indicado, realizándose únicamente biopsia o desbridamiento para el diagnóstico diferencial con patología tumoral. Conclusión: La OEM continúa siendo una enfermedad con grave morbilidad y potencialmente mortal, especialmente en pacientes ancianos y con otras comorbilidades. (AU)


Introduction and objective: Malignant external otitis (MEO) is an aggressive infection of the soft tissues of the external canal and surrounding structures, which can spread and involve the skull base and the temporomandibular joint (TMJ). It mainly affects immunocompromised patients over 65 years of age. The objective of this study has been to know the characteristics of patients diagnosed with MEO in our hospital in recent years and to establish the diagnosis and therapeutic criteria for this rare disease. Method: A descriptive, observational, and retrospective study of patients diagnosed with MEO at the University Clinical Hospital (Valladolid, Spain) between 1996 and 2021 was carried out. Results: Nine patients were diagnosed with MEO in the last 25 years, 78% male (7/9), and with a mean age of 76.8 years. All patients manifested the disease early with otalgia, otorrhea and granulation tissue in the external auditory canal (EAC). None had cranial nerve involvement, but four had TMJ invasion and two of the nine patients in the sample died. Discussion: Currently the diagnosis of MEO is established from a variety of clinical, laboratory and radiographic findings. Antimicrobial therapy depends on the severity of the infection. Since the availability of systemic antipseudomonal antibiotics, surgical treatment of this pathology is not indicated initially, performing only biopsy or debridement for differential diagnosis with tumor pathology. Conclusion: MEO continues to be a disease with serious morbidity and maximum mortality, especially in elderly patients and with other comorbidities. (AU)

ABSTRACT

Acute massive gastric dilatation is a rare condition mainly seen in patients with alimentary disorders. This massive distention may cause gastric necrosis and even perforation and emphysematous gastritis. We report the case of an 18-year-old female with intense abdominal pain and signs of sepsis. Computed-tomography scan diagnosed an acute massive gastric distention within gas into the gastric wall. Despite rapid instauration of conservative treatment, the patient finally underwent surgery. It is important to discard this infrequent pathology even in young and healthy people. An early diagnosis is crucial, a rapid instauration of conservative management may be effective and avoid surgery.


La distensión gástrica masiva es una condición rara, principalmente descrita en pacientes con trastornos de la conducta alimentaria, que puede evolucionar hacia una necrosis, perforación o gastritis enfisematosa. Reportamos el caso de una paciente de 18 años valorada por intenso dolor abdominal y sepsis, diagnosticada de distensión gástrica masiva. A pesar del tratamiento conservador, la paciente requirió cirugía urgente. Es importante descartar esta entidad cuando valoramos a un paciente en Urgencias ya que es una patología infrecuente presente en gente joven y sana. Un diagnóstico temprano es crucial porque el tratamiento conservador precoz puede ser eficaz y evitar la cirugía.
