Absceso periamigdalino bilateral. Reporte de un caso y revisión de las controversias en el diagnóstico y tratamiento / Bilateral peritonsillar abscess. A case report and review of controversies surrounding diagnosis and management

La presentación bilateral del absceso periamigdalino es poco frecuente. Su abordaje es controversial y se discute si realizar amigdalectomía en caliente versus diferida. Se presenta el caso de un paciente de sexo masculino, de 14 años, con odinofagia, trismo y fiebre. Presentaba hipertrofia amigdalina bilateral, pilares abombados y edema de paladar blando. Tomografía computada: hipertrofia amigdalina bilateral, con realce poscontraste, ambas con colección, edema con moderada estenosis faríngea. Se decidió internación para tratamiento endovenoso y amigdalectomía con drenaje bilateral. Resolución completa del cuadro con alta a las 48 horas. Ante la presencia de un absceso periamigdalino, debe considerarse la posibilidad de un absceso contralateral oculto. Debe ser diagnosticado y tratado adecuadamente para prevenir complicaciones. La amigdalectomía en caliente podría ser un tratamiento seguro y debería ser considerado en pacientes que serán sometidos a anestesia para drenaje. La decisión final debe ser determinada para cada caso en particular.

The bilateral presentation of peritonsillar abscess is uncommon. Its management is controversial and it has been argued whether a quinsy tonsillectomy or an interval tonsillectomy should be performed. Here we describe the case of a 14-year-old boy with sore throat, trismus, and fever. He had bilateral tonsillar hypertrophy, convex arches, and soft palate edema. Computed tomography: bilateral tonsillar hypertrophy, with post-contrast enhancement, both with collection, edema with moderate pharyngeal stenosis. The patient was hospitalized for intravenous therapy and tonsillectomy with bilateral drainage resulting in a complete resolution of his condition and discharge at 48 hours. In the presence of a peritonsillar abscess, an unsuspected contralateral abscess should be considered. It should be diagnosed and managed adequately to prevent complications. Quinsy tonsillectomy could be safe and should be considered in patients who will undergo anesthesia for abscess drainage. The final decision should be made for each patient on an individual basis.

Skin abscess after the use of transdermal buprenorphine. Case report / Abscesso cutâneo após o uso de buprenorfina transdérmica. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: Buprenorphine is a partial agonist semi-synthetic opioid used as an option in the treatment of patients with moderate to severe pain. The only presentation of buprenorphine available in Brazil is for transdermal use. This is an important route of drug administration, especially for the treatment of chronic pain, as it has several advantages, however it is not free from complications. The objective of this study was to present a serious adverse skin reaction after the use of transdermal buprenorphine, requiring surgical intervention. CASE REPORT: Female patient, 63 years old, hypertensive and diabetic, diagnosed with rheumatoid arthritis, fibromyalgia syndrome and lumbar disc herniation, with severe chronic pain, advised to use transdermal buprenorphine 10 mg to help control algic. After 24 hours of use, the patient developed erythema and local itching, requiring removal of the adhesive, but the lesion progressively worsened with the formation of an abscess and the need for surgical drainage. CONCLUSION: Transdermal buprenorphine has a favorable safety and tolerability profile, as it reduces the risk of unwanted effects such as respiratory depression, constipation and suicidal ideation. However, its use in senior patients with comorbidities, such as the immunosuppression described in this case, requires greater vigilance, due to the possibility of developing more serious adverse reactions.

RESUMO JUSTIFICATIVA E OBJETIVOS: A buprenorfina é um opioide agonista parcial semissintético utilizado como opção no tratamento de pacientes com dor de moderada a intensa. A única apresentação disponível da buprenorfina no Brasil é para uso por via transdérmica. Esta é uma via importante de administração de fármacos, principalmente para o tratamento de dor crônica, já que apresenta diversas vantagens, no entanto não é isenta de complicações. O objetivo deste estudo foi apresentar uma reação cutânea adversa grave após o uso de buprenorfina transdérmica, com necessidade de intervenção cirúrgica. RELATO DO CASO: Paciente do sexo feminino, 63 anos, hipertensa e diabética, com diagnósticos de artrite reumatoide, síndrome fibromiálgica e hérnia de disco lombar, portadora de dor crônica intensa, com orientação de utilizar buprenorfina transdérmica 10 mg para auxiliar o controle álgico. Após 24 h de uso, a paciente evoluiu com eritema e prurido local, sendo indicada a remoção do adesivo, porém a lesão piorou progressivamente com formação de abscesso e necessidade de drenagem cirúrgica. CONCLUSÃO: A buprenorfina transdérmica apresenta um perfil favorável de segurança e tolerabilidade, pois reduz o risco de efeitos indesejados, como depressão respiratória, constipação e ideação suicida. No entanto, seu uso em pacientes idosos portadores de comorbidades, como a imunossupressão descrita no caso, exige maior vigilância, devido à possibilidade de desenvolvimento de reações adversas mais graves.

Molecular mechanism of Xuebijing in treating pyogenic liver abscess complicated with sepsis / 世界急诊医学杂志（英文）

@#BACKGROUND: Xuebijing (XBJ) can alleviate the inflammatory response, improve organ function, and shorten the intensive care unit (ICU) stay in patients with pyogenic liver abscess (PLA) complicated with sepsis, but the molecular mechanisms have not been elucidated. This study aimed to explore the molecular mechanism of XBJ in treating PLA complicated with sepsis using a network pharmacology approach. METHODS: The active ingredients and targets of XBJ were retrieved from the ETCM database. Potential targets related to PLA and sepsis were retrieved from the GeneCards, PharmGKB, DisGeNet, Online Mendelian Inheritance in Man (OMIM), Therapeutic Targets Database (TTD), and DrugBank databases. The targets of PLA complicated with sepsis were mapped to the targets of XBJ to identify potential treatment targets. Protein-protein interaction networks were analyzed using the STRING database. Potential treatment targets were imported into the Metascape platform for Gene Ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Molecular docking was performed to validate the interactions between active ingredients and core targets. RESULTS: XBJ was found to have 54 potential treatment targets for PLA complicated with sepsis. Interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor (TNF) were identified as core targets. KEGG enrichment analysis revealed important pathways, including the interleukin-17 (IL-17) signaling pathway, the TNF signaling pathway, the nuclear factor-kappa B (NF-κB) signaling pathway, and the Toll-like receptor (TLR) signaling pathway. Molecular docking experiments indicated stable binding between XBJ active ingredients and core targets. CONCLUSION: XBJ may exert therapeutic effects on PLA complicated with sepsis by modulating signaling pathways, such as the IL-17, TNF, NF-κB, and TLR pathways, and targeting IL-1β, IL-6, and TNF.

Abscesos renales bilaterales multifocales por Candida albicans / Bilateral multifocal kidney abscess due to Candida al bicans

Resumen Los abscesos renales son una complicación poco frecuente de las infecciones del tracto urinario y suelen asociarse con un aumento de la morbi-mortalidad. La mayoría de los casos ocurre en pacientes con factores predisponentes como la inmunosupresión. El diagnóstico requiere de una elevada sospecha clínica y el trata miento consiste en el uso de antibióticos y antifúngicos parenterales asociados o no a intervenciones quirúrgicas como nefrostomía y nefrectomía. Son pocos los casos publicados en la literatura médi ca de abscesos renales bilaterales multifocales y menos aún por Candida albicans. Se presenta el caso de una mujer de 20 años de edad con diabetes mellitus tipo 1 diagnosticada a los 8 años, múltiples internaciones por cetoacidosis diabética y reciente internación por can didemia (Candida albicans) completando tratamiento con fluconazol por 23 días. A los 18 días de su externación, consulta por dolor en flancos de tipo sordo y síntomas ge nerales; se realizó tomografía de abdomen con contraste que mostró abscesos multifocales bilaterales. Aislándose Candida albicans en una de las muestras obtenidas de las lesiones; recibió tratamiento con fluconazol 400 mg por 6 semanas endovenoso y 2 semanas vía enteral, evolu cionando favorablemente con mejoría clínica e image nológica continuando seguimiento clínico ambulatorio. Este reporte resalta la importancia del diagnóstico y tratamiento de esta complicación infrecuente en enfer medades complejas como la diabetes.

Abstract Renal abscesses are a rare complication of urinary tract infections and may be associated with increased morbidity and mortality. Most cases occur in patients with predisposing factors such as immunosuppression. Diagnosis requires high clinical suspicion and its treat ment consists in the use of parenteral antibiotics and antifungals associated or not with surgical interventions such as nephrostomy and nephrectomy. Few cases have been published in the medical literature of multifocal bilateral renal abscesses and even fewer due to Candida albicans. We present the case of a 20-year-old woman with type 1 diabetes mellitus, diagnosed at age 8, multiple hospitalizations for diabetic ketoacidosis, and recent hospitalization for candidemia (Candida albicans) treated with fluconazole for 23 days. Eighteen days after her discharge, she consulted for dull flank pain and gen eral symptoms. Contrast enhanced abdominal tomography showed bilateral multifocal abscesses and Candida albicans was isolated in one of the samples obtained from lesions. She received fluconazole 400 mg, 6 weeks i.v. and 2 weeks via enteral route, evolving favorably with clinical and imag ing improvement, continuing outpatient clinical monitoring. This report highlights the importance of diagnosis and treatment of this rare complication in complex diseases such as diabetes mellitus.

Absceso de Brodie en la clavícula: una forma poco frecuente de presentación / Brodie abscess in the clavicle: an uncommon presentation

La osteomielitis (OM) se define como la inflamación ósea de origen infeccioso. La forma aguda es frecuente en la edad pediátrica. El absceso de Brodie es un tipo de osteomielitis subaguda, históricamente con baja incidencia, pero que actualmente se presenta un aumento de la misma. De poca repercusión clínica, con pruebas de laboratorio inespecíficas y estudios radiológicos de difícil interpretación, es crucial la sospecha diagnóstica. Se asemeja a procesos neoplásicos, benignos o malignos. Recae en la experiencia del profesional realizar el diagnóstico adecuado. El tratamiento consiste en antibioticoterapia, tanto parenteral como por vía oral, y eventualmente drenaje quirúrgico. Presentamos una paciente sana que consultó por una tumoración en topografía de clavícula izquierda de 3 meses de evolución. Se realizó diagnóstico de absceso de Brodie, inició tratamiento y se obtuvo una buena respuesta. Resulta imprescindible tener un alto índice de sospecha de esta entidad para no someter al paciente a estudios, pruebas invasivas o tratamientos erróneos, y evitar secuelas a futuro.

Osteomyelitis is defined as an inflammation of the bone caused by infection. Acute osteomyelitis is common in pediatrics. A Brodie abscess is a type of subacute osteomyelitis, with a historically low incidence; however, its incidence is currently increasing. Given its little clinical impact, with non-specific laboratory tests and radiological studies of difficult interpretation, diagnostic suspicion is crucial. It resembles neoplasms, either benign or malignant. An adequate diagnosis falls on the health care provider's experience. Treatment consists of antibiotics, both parenteral and oral, with potential surgical drainage. Here we describe the case of a healthy female patient with a tumor found in the topography of the left clavicle 3 months before. She was diagnosed with Brodie abscess; treatment was started with a good response. A high index of suspicion of Brodie abscess is critical to avoid invasive tests and studies or inadequate treatments, and to prevent future sequelae.

Absceso del psoas secundario a apendicitis atípica en gestante. Presentación de un caso

El absceso del psoas es una enfermedad infecciosa infrecuente y de difícil diagnóstico, caracterizado por una colección purulenta a nivel de este músculo, que provoca un síndrome de respuesta inflamatoria sistémica. La infección puede ser primaria por diseminación hematógena, o secundaria, a partir de un foco infeccioso cercano. Su presentación durante el embarazo es rara, y predomina la forma primaria, razón por la cual se decidió realizar este artículo. Se presenta el caso de una gestante con 28,4 semanas de edad gestacional que ingresó por dolor inguinal con posterior irradiación a la cadera, flanco y región lumbar derechos; postura en flexión de la cadera derecha y marcha antiálgica, así como aparición, a los nueve días de iniciados los síntomas, de una masa dolorosa entre fosa ilíaca y flanco derechos. Los hallazgos de la ecografía abdominal y la resonancia permitieron el diagnóstico de un plastrón apendicular con un apéndice retrocecal, así como absceso del psoas derecho, los cuales se trataron con antibioticoterapia y drenaje percutáneo del absceso, con resultados satisfactorios. El absceso del psoas secundario puede constituir el debut de una apendicitis atípica retrocecal, y para su diagnóstico hay que tener un alto nivel de sospecha por su clínica inespecífica.

The psoas abscess is a rare infectious disease that is difficult to diagnose, characterized by a purulent collection at the level of this muscle, which causes a systemic inflammatory response syndrome. The infection can be primary by hematogenous dissemination, or secondary, from a nearby infectious focus. Its presentation during pregnancy is rare, and the primary form predominates, which is why it was decided to write this article. The case of a pregnant woman with a gestational age of 28.4 weeks who was admitted due to inguinal pain with subsequent irradiation to the right hip, flank, and lumbar region; flexed posture of the right hip and analgesic gait, as well as the appearance, nine days after the onset of symptoms, of a painful mass between the right iliac fossa and flank it is presented. The findings of the abdominal ultrasound and MRI allowed the diagnosis of an appendiceal plastron with a retrocecal appendix, as well as a right psoas abscess, which were treated with antibiotic therapy and percutaneous drainage of the abscess, with satisfactory results. Secondary psoas abscess may constitute the debut of atypical retrocecal appendicitis, and its diagnosis requires a high level of suspicion due to its non-specific symptoms.

Genetic polymorphism of interleukins 6 and 17 correlated with apical periodontitis: A Cross-sectional study

Abstract Interleukins 6 and 17 act in bone resorption in the presence of infections of endodontic origin for host defense. Genetic polymorphisms may be associated with increased bone loss, represented by areas of large periapical lesions. This study aimed to verify the frequency of interleukin 6 and 17 gene polymorphism in patients with asymptomatic apical periodontitis or chronic apical abscess and to verify the existence of correlations between periapical lesion area with age, gender, and presence of the polymorphism, in the studied population, in the state of Pernambuco. A population consisting of thirty diagnosed individuals was included. The area of the lesions was measured in mm². Genomic DNA was extracted and genotyping was performed by Polymerase Chain Reaction Restriction Fragment Length Polymorphism for interleukin 6 (rs 1800795) and interleukin 17 (rs 2275913). Fisher's exact, chi-square, and odds ratio tests were used. A logistic regression analysis was also performed using sex, age, and the presence of polymorphism as covariates, in addition to linear regression to test the relationship between age and lesion area. All tests used a significance level of 0.05% (p ≤0.05%). There was no statistical significance in the occurrence of large areas of periapical lesions correlated with age, sex, and diagnosis, nor in the distribution of alleles in the polymorphism of interleukins 6 and 17 in the studied groups. The frequency of homozygous and heterozygous polymorphism was high. The polymorphism of these interleukins is not correlated with the increase in the areas of asymptomatic periapical inflammatory lesions.

Resumo As interleucinas 6 e 17 atuam na reabsorção óssea na presença de infecções de oriegem endodôntica para defesa do hospedeiro. Polimorfismos genéticos podem estar associados ao aumento da perda óssea, representada por áreas de lesões periapicais grandes. O objetivo deste estudo foi verificar a frequência do polimorfismo dos genes interleucina 6 e 17 em pacientes com periodontite apical assintomática ou abscesso apical crônico e verificar a existência de correlações entre área de lesão periapical com idade, sexo e presença do polimorfismo, na população estudada, no estado de Pernambuco. Foi incluída uma população constituída por trinta indivíduos diagnosticados. A áreas da lesões foram medidas em mm². O DNA genômico foi extraído e a genotipagem realizada por Polimorfismo de Comprimento de Fragmento de Restrição de Reação em Cadeia da Polimerase para interleucina 6 (rs 1800795) e interleucina 17 (rs 2275913). Os testes exato de Fisher, qui-quadrado e odds ratio foram utilizados. Uma análise de regressão logística também foi realizada usando sexo, idade e presença de polimorfismo como covariável, além de regressão linear para testar a relação da idade e área da lesão. Todos os testes utilizaram um nível de significância de 0,05% (p ≤0.05%). Não houve significância estatística na ocorrência das áreas grandes de lesões periapicais correlacionadas com idade, sexo e diagnóstico nem nas distribuições de alelos no polimorfismo das interleucinas 6 e 17 nos grupos estudados. A frequência de polimorfismo homozigoto e heterozigoto foi alta. O polimorfismo dessas interleucinas não está correlacionado ao aumento das áreas das lesões inflamatórias periapicais assintomáticas.

¿Plastrón o tumor apendicular? / Plastron appendicitis or appendiceal tumor?

Un plastrón apendicular es una masa apendicular palpable que contiene el apéndice inflamado, vísceras adyacentes y el omento mayor, asociado a o no a la presencia de pus. El manejo del plastrón apendicular abscedado es controvertido. Cuando hay signos de sepsis asociados, la indicación es una intervención quirúrgica de urgencia, de lo contrario puede optarse por un tratamiento conservador. La utilización de drenaje percutáneo tiene una alta tasa de efectividad, aunque la tasa de neoplasias no detectadas presenta un porcentaje no despreciable, especialmente en los pacientes mayores de 40 años. El objetivo de esta presentación es comunicar una paciente de 65 años con diagnóstico presuntivo de plastrón apendicular abscedado quien luego del fracaso de los drenajes percutáneos fue sometida a una laparotomía exploratoria y hemicolectomía derecha. El diagnóstico histopatológico fue de adenocarcinoma mucinoso del apéndice. (AU)

A palpable inflammatory appendiceal mass may contain the inflamed appendix, adjacent viscera, and the greater omentum, associated or not with the presence of pus. The management of an inflammatory appendiceal mass is controversial. When there are associated signs of sepsis, the indication is emergency surgery, otherwise, you can opt for a conservative treatment. The use of percutaneous drainage has a high rate of effectiveness, although the rate of undetected neoplasia is not negligible, especially in patients older than 40 years. We present the case of a 65-year-old female patient with a presumptive diagnosis of an appendiceal mass with abscess, who underwent exploratory laparotomy and right hemicolectomy after percutaneous drainage failure. The histopathological diagnosis was mucinous adenocarcinoma of the appendix. (AU)

Massive pleural empyema secondary to amoebic liver abscess in a child / Empiema pleural masivo secundario a absceso hepático amebiano en un niño

Abstract Background: Pleural empyema secondary to a ruptured amoebic liver abscess is a rare complication in the pediatric population. Case report: We report the case of a 13-year-old male with right flank abdominal pain, productive cough with foul-smelling sputum, fever, and respiratory distress. Physical examination revealed breathlessness, decreased vesicular murmur in the right hemithorax, abdominal distension, hepatomegaly, and lower limb edema. Laboratory tests revealed mild anemia, leukocytosis without eosinophilia, elevated alkaline phosphatase, hypoalbuminemia, and positive immunoglobulin G antibodies against Entamoeba histolytica in pleural fluid. He required a chest tube and treatment with metronidazole. After 2 months of follow-up, the abscesses disappeared, and the empyema decreased. Conclusions: Massive pleural empyema secondary to a ruptured liver abscess is a rare complication. The epidemiological link associated with the symptoms and serological tests can help in the diagnosis.

Resumen Introducción: El empiema pleural secundario a ruptura de absceso amebiano hepático es una complicación poco frecuente en la población pediátrica. Caso clínico: Se reporta el caso de un paciente de sexo masculino de 13 años que presentó dolor abdominal en flanco derecho, tos productiva con esputo de mal olor, fiebre y dificultad respiratoria. Al examen físico se encontró amplexación y murmullo vesicular disminuido en hemitórax derecho, distensión abdominal, hepatomegalia y edema de miembros inferiores. Los resultados del laboratorio evidenciaron anemia leve, leucocitosis sin eosinofilia, elevación de fosfatasa alcalina, hipoalbuminemia y anticuerpos IgG contra Entamoeba histolytica positivo en líquido pleural. Requirió tubo de drenaje torácico y tratamiento con metronidazol. A los dos meses de seguimiento los abscesos desaparecieron y el empiema disminuyó. Conclusiones: El empiema pleural masivo secundario a ruptura de absceso hepático es una complicación poco frecuente. El nexo epidemiológico asociado con la sintomatología y pruebas serológicas pueden ser de ayuda en el diagnóstico.

Abscesos renales: experiencia en un hospital pediátrico de referencia

Introducción: El absceso renal es infrecuente en pediatría, con clínica y laboratorio inespecíficos. Ante su sospecha, es necesario realizar imágenes para establecer diagnóstico. Objetivo: Describir las características clínico-epidemiológicas, microbiológicas, diagnósticas y terapéuticas de abscesos renales en pediatría. Pacientes y Métodos: Estudio retrospectivo, descriptivo, de pacientes internados con absceso renal, en seguimiento por Infectología del Hospital de Niños Ricardo Gutiérrez, durante 9 años. Resultados: 15 pacientes (67% varones), mediana de edad 9 años (rango [r] 0,7-17). Cuatro pacientes con comorbilidades. El síntoma más frecuente fue fiebre seguido por dolor lumbar. El recuento medio de leucocitos en sangre fue de 15.700/mm3 (r: 7.100-45.000) y la PCR de 193 mg/L (r: 1-362). Cuatro pacientes presentaron urocultivo positivo: dos Escherichia coli, uno Klebsiella pneumoniae y E. coli y otro Candida albicans y K. pneumoniae. Ningún paciente presentó bacteriemia. El diagnóstico se confirmó por ecografía. Se realizó drenaje en siete pacientes, con aislamiento de Staphylococcus aureus en dos y Pseudomonas aeruginosa en uno. El tratamiento incluyó terapia combinada en 67%. Mediana de antibioterapia intravenosa fue 16 días (r: 7-49), total de 28 (r: 14-91). Un paciente requirió terapia intensiva y dos, nefrectomía. Conclusión: Los abscesos renales son infrecuentes, con gran morbimortalidad. Sospechar en paciente con infección del tracto urinario (ITU) de evolución tórpida que persiste febril. En nuestro estudio, la alta sensibilidad de la ecografía renal permitió su diagnóstico precoz.

Background: Renal abscesses are infrequent in pediatrics, with nonspecific clinical and laboratory findings. When suspected, imaging is essential to establish the diagnosis. Aim: To describe the clinical-epidemiological, microbiological, diagnostic and therapeutic characteristics of renal abscesses in pediatrics. Methods: Retrospective and descriptive study of hospitalized patients with renal abscess, followed by Infectious Diseases Department of Ricardo Gutiérrez Children's Hospital during 9 years. Statistical analysis: Epi Info 7.2.2.6. Results: 15 patients (67% male), median age 9 years (range [r] 0.7-17) were included. Four patients had underlying disease. The most frequent symptom was fever, with a median duration of 10 days (r:1-36), followed by lumbar pain. The median white blood cell count was 15,700/mm3 (r: 7,100-45,000) and CRP 193mg/L (r: 1-362). Four patients presented positive urine culture: 2 Escherichia coli, 1 Klebsiella pneumoniae and E. coli and 1 Candida albicans and K. pneumoniae. No patient had bacteremia. The diagnosis of abscess was confirmed by ultrasound. Surgical drainage was performed in 7 patients, with isolation of Staphylococcus aureus in 2 and Pseudomonas aeruginosa in 1. Empirical treatment included 3rd generation cephalosporin, combined in 67% of cases. The median of intravenous antibiotic therapy was 16 days (r: 7-49) with a total of 28 days (r:14-91). One patient required transfer to intensive care unit and 2 nephrectomy. Conclusion: Renal abscesses are infrecuent in pediatrics, but they present significant morbidity and mortality. It should be suspected in patients with urinary tract infection (UTI)with torpid evolution that persists with fever without antibiotic response. In our study, the high sensitivity of renal ultrasound allowed early diagnosis.

Absceso esplénico en un paciente adulto. Reporte de caso

El absceso esplénico es una entidad poco común. Se define como la presencia de una lesión ocupante de espacio en el bazo asociada a infección. Ha sido descrito en 0,14-0,7 % de los estudios de autopsias. Se presenta el caso de un paciente de 60 años, de color de piel blanca, que acudió al hospital por presentar fiebre y diarreas, con dolor en fosa lumbar izquierda. Fue ingresado y trasladado a Unidad de Cuidados Intensivos debido a fallo renal agudo por deshidratación. Al trasladarse a sala abierta se diagnosticó un absceso esplénico mediante ultrasonido y tomografía. No se decidió operar en ese momento porque no tenía criterio. Posteriormente sufrió de abdomen agudo y shock séptico por ruptura del absceso hacia cavidad abdominal y fue intervenido de urgencia; se realizó esplenectomía y toilette de la cavidad. Su evolución posterior fue favorable. Por lo poco común de esta entidad, se decidió la publicación del caso.

The splenic abscess is a rare entity. It is defined as the presence of a space-occupying lesion in the spleen associated with infection. It has been described in 0.14-0.7% of autopsy studies. The case of a 60-years-old patient, white-skinned, who came to the hospital due to fever and diarrhea, with pain in the left lumbar fossa is presented. He was admitted and transferred to the Intensive Care Unit due to acute renal failure due to dehydration. When transferred to the open room, a splenic abscess was diagnosed by ultrasound and tomography. It was not decided to operate at that time because there are no criteria. Subsequently, he presented acute abdomen and septic shock due to rupture of the abscess into the abdominal cavity and underwent emergency surgery, performing splenectomy and the cavity's toilette. His subsequent evolution was positive. Due to the unusual nature of this entity, it was decided to publish the case.

Abscesos cerebrales por Dermacoccus nishinomiyaensis como primera manifestación de enfermedad granulomatosa crónica / Dermacoccus nishinomiyaensis brain abscesses as the first manifestation of chronic granulomatous disease

La enfermedad granulomatosa crónica es una inmunodeficiencia primaria poco frecuente, que secaracteriza por defectos en alguna de las subunidades del complejo enzimático nicotinamida adeninadinucleótido fosfato oxidasa, que ocasiona un déficit en la generación de anión superóxido por losfagocitos. Dentro de este grupo, la forma ligada al X es la más frecuente. Se reporta el caso de una paciente de sexo femenino de 2 años con enfermedad granulomatosa crónica autosómica recesiva, con mutación en gen CYBA, quien presentó manifestación inicial de la enfermedad con abscesos cerebrales ocasionados por un germen oportunista (Dermacoccus nishinomiyaensis). Esta infección permitió la sospecha diagnóstica temprana, por lo que recibió el tratamiento y la profilaxis en forma oportuna. Actualmente, se encuentra libre de infecciones, a la espera del trasplante de células progenitoras hematopoyéticas.

Chronic granulomatous disease is a rare primary immunodeficiency characterized by defects in one of the subunits of the nicotinamide adenine dinucleotide phosphate oxidase enzyme complex, which causes a deficiency in the capacity of phagocytes to generate superoxide anion. Within this group, the X-linked form is the most frequent. Here we report the case of a 2-year-old female patient with autosomal recessive chronic granulomatous disease, with a mutation in the CYBA gene, whose initial manifestation was brain abscesses caused by an opportunistic microorganism (Dermacoccus nishinomiyaensis). The infection led to an early diagnostic suspicion, so treatment and prophylaxis were administered in a timely manner. Currently, she is infectionfree, awaiting hematopoietic progenitor cell transplantation.

A Rare Case of an Intratonsillar Abscess

The case describes the anatomy and pathophysiology of the palatine tonsils and the development of intratonsillar abscess. The abscess can be caused by a suppurative focus that arises in acute tonsillitis when outward drainage is prevented, leading to pus accumulation in the tonsillar tissue. Dehydration or a history of peritonsillar abscess can also lead to intratonsillar abscess. The condition can be mistaken for tonsillolith or malignancy, such as lymphoma. A computed tomography (CT) scan is recommended for diagnosis, showing a low-density and ring enhancement. Aspiration using a large bore needle is the preferred mode of treatment, but if repeated aspirations fail, tonsillectomy may be necessary. Intratonsillar abscess is rare and so far only 29 cases have been reported.1 The differential diagnoses include lymphoma, which usually presents as unilateral enlargement of the tonsil, tonsillolith due to its appearance and peritonsillar abscess again due to the unilateral enlargement of the tonsil. This case is different as compared to other reported cases we did not do a CT scan as recommended by most of the studies (cost being a concern). Also, in this case, we resorted to surgery as the main modality unlike other cases wherein the surgeons opted to do an aspiration of the pus mainly keeping the intraoperative complications in mind.

Breast Abscess In Non Nursing Women

Background: Non Nursing Breast Abscess is formation of pus in Breast resulting from an infection in not pregnant or breastfeeding women. Incidence of such Abscess in non nursing women is although less but rising. These are either in nipple areolar region or peripheral in breast..Aim of this study is to explore the cause of Abscess,Early diagnosis, identification of organisms & sensitivity to antibiotics & to assess treatment modality. Observational StudyMethods: Results: Breast Abscess In 30 non nursing Patients of age group 28-55 yrs,developed due to Diabetes in 18 (60%), Mastitis in 6 (20%),Trauma in 3 (10%),Duct ectasia 1 (3.3%),Cacinoma 2 (6.6%) .Most frequent organism seen was Staphylococcus Aureus,but Streptococcus & Pseudomonas also isolated.Early Diagnosis was possible by Ultrasound. Incision & Drainge under Anaesthesia in 20 (66.6%) with antibiotics & treating underlying disease.Antibiotics with Percutaneous Aspiration in 5 (16.6%) and only Antibiotics in 3 (10%) Patients required. Breast Abscess inConclusions: Non Nursing Women is infrequent entity in comparison to that in Nursing Women,Early Diagnosis is possible by Ultrasound examination.Incision & drainage mostly required but Percutaneous Aspiration is also helpful.02 Patients (6.6%).with cancer didnot improve.

Clinical case: We present a case of a patient who had an intraoperative ultrasound which helped in the decision making and avoided any further invasive procedures. Conclusions: The Point of Care Ultrasound (PoCUS) is a quick and practical way to solve questions and facilitate objective decisions in the perioperative environment.

Urrets-Zavalia Syndrome after Penetrating Keratoplasty: A Case Report

Urrets-Zavalia syndrome is a dreaded complication of anterior segment surgery and the most common in patients undergoing corneal transplantation. Avoiding the prescription of mydriatic eye drops during the postoperative period is the mainstay of its therapy, which focuses on prevention. One month after having keratoplasty in the left eye, a 42-year-old man presented with Urrets-Zavalia syndrome and ocular hypertonia at 35 mmgh. Medical and surgical management were required in this situation.The purpose of our presentation is to describe a real-world instance of Urrets-Zavalia syndrome.

Persistencia de uraco en paciente joven. Reporte de caso / Persistence of urachus in a young patient. Case report

Introducción. Durante el desarrollo embrionario normal, se espera que el denominado uraco o ligamento umbilical mediano se oblitere a las 32 semanas de gestación. Ante una obliteración incompleta surgen las diferentes anomalías, siendo las más frecuentes el quiste y la fístula urinaria umbilical. El objetivo de este artículo fue presentar el caso de una paciente joven, sin comorbilidades, con quiste de uraco. Caso clínico. Mujer indígena de 19 años que consultó por dolor leve en hipogastrio, asociado a síntomas urinarios y distensión abdominal. Se sospechó en primera instancia cólico renal, pero ante hallazgos ecográficos de masa infraumbilical y reactantes de fase aguda elevados, la impresión diagnóstica cambió a sepsis secundaria a absceso intraabdominal. Posterior a tomografía y cistoscopía con calibración uretral se identificó pequeño divertículo en cúpula vesical, que sugirió el diagnóstico de uraco persistente, por lo que la paciente fue llevada a intervención quirúrgica para su resección, con evolución favorable. Discusión. El quiste de uraco es una anormalidad infrecuente, en su mayoría asintomática y generalmente de hallazgo incidental en la población anciana, por lo que se requiere de imágenes y manejo multidisciplinar para su correcto diagnóstico y abordaje. Conclusión. Son pocos los casos de uraco persistente reportados, y mucho menos en el sexo femenino. Dada la posibilidad de complicaciones tardías es importante el seguimiento para su manejo. Este caso se ha controlado de manera ambulatoria por 2 años

Introduction. During normal embryonic development, it is expected that the so-called urachus or median umbilical ligament will be obliterated at 32 weeks of gestation. In the face of incomplete obliteration, the different anomalies of the urachus arise. The most frequent anomaly of the urachus is the cyst followed by the umbilical urinary fistula. The objective of this article was to present the case of a young patient without comorbidities with urachal cyst. Clinical case. A 19-year-old indigenous woman consulted for mild hypogastric pain associated with urinary symptoms and abdominal distension. Renal colic was suspected at first, but due to ultrasound findings of an infraumbilical mass and high acute phase reactants, the diagnostic impression changed to sepsis secondary to an intra-abdominal abscess. After tomography and cystoscopy with urethral calibration, a small diverticulum was identified in the bladder dome, suggesting a diagnosis of persistent urachus, for which the patient was taken to surgery for its resection, with favorable evolution. Discussion. The urachal cyst is a rare abnormality, mostly asymptomatic and usually incidental finding in the elderly population. Imaging and multidisciplinary management are required for its correct diagnosis and approach. Conclusion. There are few reported cases of persistent urachus and much less in females. Given the possibility of late complications, follow-up is important for its management, in this case we have carried out control for 2 years

A rare diagnosis has no certainty, but still they occur: A case report

Pain and swelling are among the most frequently encountered complaints in an orthopedics outpatient department (OPD) relatively less common in a pediatric OPD. A high level of suspicion is required to diagnose bone diseases. Common conditions such as rickets, septic arthritis, and tuberculosis must be ruled out. Treatment such as antibiotics, anti-inflammatory drugs, or steroids may mask an underlying serious condition in which if left untreated can cause significant morbidity and mortality to the person. Here, we discuss a case of a young infant 11 months of age who had symptoms suggestive of septic arthritis and was later found to have Brodie’s abscess which is a type of subacute osteomyelitis on further evaluation which is usually mistaken as a tumor. This age at presentation is rare.

Urinary tract infection with renal abscess

Renal abscess is very rare among intra-abdominal abscesses in children. Ascending infection is the most common cause in children compared to hematogenous spread in adults and Escherichia coli is the main pathogen. Persisting high-grade fever is an alarming sign to intervene and has to be taken care of. Here, we are presenting the case of a 3-year-old boy with Klebsiella urinary tract infection and E. coli renal abscess of 4 cm size. Contrast-enhanced computed tomography abdomen helped in early intervention and management. The child responded very well to parenteral antibiotics and ultrasound-guided percutaneous aspiration.

Assessment of Bacteriological Pattern and Antimicrobial Susceptibility in Deep Neck Space Abscess

Background: Deep neck abscess is a common clinical entity in developing countries like ours. Despite the widespread use of antibiotics, deep neck infections do not disappear and remain one of the most difficult emergencies encountered in daily clinical practice. The extent and severity of the illness could become life-threatening. Therefore, coping with deep neck abscess remain a challenge to otolaryngologists. This study aimed to analyze the bacteriological pattern and antimicrobial susceptibility in deep neck space abscesses. Material & Methods: It was a cross-sectional observational study. 50 patients with deep neck space abscesses fulfilling the inclusion and exclusion criteria admitted to the department of ENT & Head Neck Surgery, Rangpur Medical College Hospital, Rangpur, from 1st July 2017 to 30th December 2017 were enrolled in this study. Pus from deep neck space abscess was collected by either aspiration or incision and drainage with proper aseptic measure and sent by sterile test tube to microbiology department immediately. Data were collected by detailed history taking and clinical examination & investigations with informed written consent and analyzed by SPSS (version 20). Results: In this study most commonly involved deep neck spaces were Submandibular (38%), Peritonsillar (32%), Retropharyngeal (14%), and parapharyngeal (8%) spaces. Streptococcus viridans was the most prominent organism 14 (28%) followed by Klebsiella pneumonia 9(18%) and Staph. aureus 4 (8%). The most effective antibiotic was Ceftriaxone 34(79%) followed by Cefuroxime 30 (70%) and Erythromycin 23(54%). Aerobic organisms were highly sensitive to Cefuroxime (83%) and Ceftriaxone (83%) followed by Erythromycin (48%). Anaerobic organisms were sensitive to Clindamycin (100%), Metronidazole (100%), and Erythromycin (100%) followed by Ceftriaxone (75%). Conclusion: The most frequently isolated organism in deep neck space abscesses were Streptococcus viridans and Staphylococcus aureus and sensitivity results showed the majority of isolates are susceptible to Ceftriaxone and Cefuroxime
