Abscesos de córnea bilaterales en una paciente con SIDA. Presentación de un caso y revisión de la literatura / Corneal Abscess in a patient with aids: case report and literature review

El epitelio corneal es una importante barrera de defensa que impide el ingreso de una gran variedad de microorganismos. Cualquier alteración de la superficie ocular facilita la invasión bacteriana de la córnea. El germen más frecuentemente identificado es Staphylococcus aureus. Se presenta una paciente con enfermedad debida al virus de la inmunodeficiencia humana (VIH) con diagnóstico de sida, absceso corneal bilateral y lesiones cutáneas. S.aureus meticilino resistente se aisló en hemocultivos y en material obtenido por raspado de la córnea. El absceso corneal es una entidad poco frecuente en pacientes con infección por VIH y síndrome de inmunodeficiencia adquirida.

The corneal epithelium is an important defense barrier that prevents the entry of great variety of microorganisms. Any alteration of the ocular surface facilitates bacterial invasion of the cornea. The most frequently reported germ is Staphylococcus aureus. Here, we present a patient with a diagnosis of HIV/ AIDS disease, who developed bilateral corneal abscess and skin lesions. Methicillin-resistant Staphylococcus aureus was isolated from blood cultures and corneal scrapings. Corneal abscess is a rare entity in patients with HIV and acquired immunodeficiency syndrome

Diagnosis and treatment of deep neck abscess due to congenital piriform sinus fistula in children / Diagnóstico e tratamento de abscesso cervical profundo por fístula congênita do seio piriforme em crianças

Abstract Introduction: Congenital piriform sinus fistula is a relatively rare type of disease in clinical practice, most occurring during childhood, but doctors have insufficient knowledge regarding this disease, easily misdiagnosing it. Objectives: This study aimed to identify the characteristics of deep neck abscess due to congenital piriform sinus fistula in children. Methods: We performed a retrospective study of 21 cases from January 2016 to August 2018 in our hospital. The onset age, clinical characteristics, auxiliary examination and clinical treatment of the patients was summarized to analyze the diagnosis, treatment characteristics and prognosis. Results: Children from 11 days to 12 years-old were enrolled, with an average age of 3.5 years. Twenty patients had left congenital piriform sinus fistula and 1 had right congenital piriform sinus fistula. Cervical enhanced computed tomography imaging showed gas-liquid equilibrium or air-shadow in the abscesses in 18 cases, and neck ultrasound demonstrated gas echo in the thyroid region in 10 cases. All patients underwent low temperature plasma to seal the internal fistula and returned to the hospital for electronic laryngoscope and neck ultrasound examination at 3 months, 6 months and 1 year after the surgery. No recurrence occurred in any patient. Conclusion: Congenital piriform sinus fistula is an important cause of deep neck abscess in children. The presence of purulent gas-liquid equilibrium or air shadow in cervical-enhanced computed tomography or ultrasound suggests a high possibility of the presence of an internal fistula, and endoscopic low temperature ablation can be done at the same time as the diagnostic endoscopy.

Resumo Introdução: A fístula congênita do seio piriforme é uma doença relativamente rara na prática clínica; a maioria se manifesta na infância; entretanto, os médicos geralmente têm conhecimento insuficiente sobre essa condição clínica e seu diagnóstico é facilmente feito de forma errônea. Objetivo: Identificar as características do abscesso cervical profundo devido à fístula congênita de seio piriforme em crianças. Método: Estudo retrospectivo de 21 casos de janeiro de 2016 a agosto de 2018 em nosso hospital. Idade de início, características clínicas, exames auxiliares e tratamento clínico dos pacientes foram resumidos para analisar o diagnóstico, as características do tratamento e o prognóstico. Resultados: Foram incluídas crianças de 11 dias a 12 anos, com média de 3,5 anos. Vinte pacientes tinham fístula congênita de seio piriforme no lado esquerdo e um no lado direito; a tomografia computadorizada cervical com contraste mostrava distribuição líquido-gasosa ou sombra aérea nos abscessos em 18 casos. O ultrassom cervical demonstrou eco gasoso na região da tireoide em 10 casos. Todos os pacientes foram submetidos a plasma de baixa temperatura para queimar a fístula interna e retornaram ao hospital para exame com laringoscópio eletrônico e ultrassonografia cervical aos 3 meses, 6 meses e um ano após a cirurgia. Não houve recorrências. Conclusão: A fístula congênita de seio piriforme é uma causa importante de abscesso cervical profundo em crianças. A presença de conteúdo líquido-gasoso purulento ou sombra gasosa na tomografia computadorizada ou no ultrassom cervical sugere uma alta possibilidade da presença de uma fístula interna e a ablação endoscópica a baixa temperatura pode ser feita ao mesmo tempo que a endoscopia diagnóstica.

Consideraciones actuales concernientes al tratamiento del plastrón apendicular / Current Considerations Concerning Treatment of Appendiceal Plastron

Introducción: El plastrón apendicular es una tumoración inflamatoria constituida por el apéndice inflamado, vísceras adyacentes y epiplón mayor. Puede contener o no pus (absceso/flemón). Objetivo: Precisar si está indicada la apendicectomía de urgencia o de intervalo en los pacientes con plastrón y/o absceso apendicular sometidos a tratamiento no quirúrgico inicial. Métodos: Se realizó una revisión en las bases de datos bibliográficas Web of Science, PubMed, Medline y Lilacs, mediante el motor de búsqueda Google académico. Se seleccionaron 28 artículos en inglés y español; 20 (71,2 por ciento) correspondieron al quinquenio 2016-20 y el 96,4 por ciento de autores extranjeros. Desarrollo: El estándar actual es el tratamiento no quirúrgico inicial del plastrón y el drenaje percutáneo del absceso. La apendicectomía de intervalo tiene un beneficio mínimo y puede conducir a un aumento de los costos, estancia hospitalaria, antibioticoterapia intravenosa y de la morbilidad. Se debe realizar un seguimiento cuidadoso en enfermos con riesgo de enfermedad inflamatoria intestinal o cáncer de colon, sin importar qué opción se elija (operación de intervalo u observación). Conclusiones: La apendicectomía de urgencia no es recomendable porque el componente inflamatorio la hace técnicamente difícil, puede necesitar una colectomía y aumentar la morbilidad, aunque actualmente, la apendicectomía laparoscópica de urgencia puede ser más rentable y segura. La decisión posterior de la apendicectomía a intervalos sigue siendo discutible. El intervalo recomendado varía entre 6 y 8 semanas, tres y seis meses después de la normalización clínico humoral(AU)

Introduction: Appendiceal plastron is an inflammatory tumor made up of inflamed appendix, adjacent viscera and greater omentum. It may or may not contain pus (abscess/phlegmon). Objective: To specify whether emergency or interval appendectomy is indicated in patients with appendicular abscess and/or plastron who had undergone initial nonsurgical treatment. Methods: A review was carried out in the bibliographic databases Web of Science, PubMed, Medline and Lilacs, using the search engine Google Scholar. Twenty-eight articles were selected, in English and Spanish; twenty (71.2 percent) corresponded to the quinquennium 2016-20, while 96.4 percent were written by foreign authors. Development: The current standard is the initial nonsurgical treatment of the plastron and percutaneous drainage of the abscess. Interval appendectomy has minimal benefits and can lead to increased costs, hospital stay, intravenous antibiotic therapy and morbidity. Patients at risk for inflammatory bowel disease or colon cancer should be carefully followed up, regardless of which option is chosen (interval operation or observation). Conclusions: Emergency appendectomy is not recommended because the inflammatory component makes it technically difficult; it may require colectomy and increase morbidity, although currently, emergency laparoscopic appendectomy may be more profitable and safer. The subsequent decision for interval appendectomy remains debatable. The recommended interval varies from six to eight weeks, three and six months after clinical-humoral normalization(AU)

Abdominal and pelvic actinomycosis due to longstanding intrauterine device: a slow and devastating infection

Actinomycosis is a chronic or subacute bacterial infection characterized by large abscess formation, caused mainly by the gram-positive non-acid-fast, anaerobic, or microaerophilic/capnophilic, obligate parasites bacteria from the genus. Although pelvic inflammatory disease is an entity associated with the longstanding use of intrauterine devices (IUDs), actinomycosis is not one of the most frequent infections associated with IUDs. We present the case of a 43-year-old female patient who was referred to the emergency facility because of a 20-day history of abdominal pain with signs of peritoneal irritation. Imaging exams revealed collections confined to the pelvis, plus the presence of an IUD and evidence of sepsis, which was consistent with diffuse peritonitis. An exploratory laparotomy was undertaken, and a ruptured left tubal abscess was found along with peritonitis, and a huge amount of purulent secretion in the pelvis and abdominal cavity. Extensive lavage of the cavities with saline, a left salpingo-oophorectomy, and drainage of the cavities were performed. The histopathological examination of the surgical specimen revealed an acute salpingitis with abscesses containing sulfur granules. Therefore, the diagnosis of abdominal and pelvic actinomycosis was made. The postoperative outcome was troublesome and complicated with a colocutaneous fistula, which drained through the surgical wound. A second surgical approach was needed, requiring another extensive lavage and drainage of the recto-uterine pouch, plus the performance of a colostomy. Broad-spectrum antibiotics added to ampicillin were the first antimicrobial regimen followed by 4 weeks of amoxicillin during the outpatient follow-up. The patient satisfactorily recovered and is already scheduled for the intestinal transit reconstitution.

Análise da ocorrência de evento adverso pós-vacinação decorrente de erro de imunização / Análisis de la ocurrencia de eventos adversos posvacunales debido a errores de inmunización / Analysis of adverse events following immunization caused by immunization errors

RESUMO Objetivo: analisar a ocorrência de Evento Adverso Pós-Vacinação (EAPV) decorrente de erro de imunização, no Paraná, de 2003 a 2013. Método: pesquisa descritiva documental, retrospectiva, quantitativa, utilizando dados secundários do Sistema de Informação de Evento Adverso Pós-Vacinação e do Sistema de Avaliação do Programa de Imunizações. Foram incluídos casos confirmados e/ou associados a outras vacinas. Para análise foram estimadas frequências, taxas de incidência e utilizados Modelos de Regressão Linear Simples com teste t-Student. Resultados: observou-se aumento da notificação de EAPV decorrente de erro de imunização, principalmente abscesso subcutâneo quente. BCG foi a vacina com maior incidência de eventos adversos, sendo que os menores de um ano, os mais atingidos. Conclusão: o cenário atual é preocupante, pois são EAPV evitáveis - que causam danos, ligados a prática da enfermagem, decorrentes de desvios da qualidade em vacinação - que podem interferir na confiança da população (reduzindo coberturas vacinais) e no controle de doenças imunopreveníveis.

RESUMEN Objetivo: analizar la ocurrencia de Eventos Adversos Posvacunales (EAPV) debido a errores de inmunización, en Paraná, de 2003 a 2013. Método: investigación descriptiva documental, retrospectiva, cuantitativa, utilizando datos secundarios del Sistema de Información de Eventos Adversos Posvacunales y del Sistema de Evaluación del Programa de Inmunizaciones. Se incluyeron casos confirmados y/o asociados con otras vacunas. Para el análisis, se estimaron frecuencias, tasas de incidencia y se utilizaron Modelos de Regresión Lineal Simple con prueba t-Student. Resultados: se observó un aumento de la notificación de EAPV debido a errores de inmunización, principalmente abscesos subcutáneos calientes. BCG fue la vacuna con mayor incidencia de eventos adversos, siendo los menores de un año el grupo más afectado. Conclusión: la situación actual es preocupante, ya que son EAPV prevenibles - que causan daños, vinculados a la práctica de enfermería, resultantes de las desviaciones de la calidad en la vacunación - que pueden afectar la confianza de la población (reduciendo las coberturas de vacunación) y el control de enfermedades inmunoprevenibles.

ABSTRACT Objective: to analyze adverse events following immunization (AEFI) caused by immunization error in the state of Paraná, Brazil, from 2003 to 2013. Method: this is a descriptive, documental, retrospective, and quantitative research using secondary data from the Adverse Event Following Immunization Information System and the Immunization Program Evaluation System. We included cases confirmed and/or associated with different types of vaccines. For the analysis, we collected frequencies and incidence rates, and used simple linear regression models with Student's t-test. Results: it was observed an AEFI increase due to immunization errors, especially hot subcutaneous abscesses. BCG vaccine had the highest incidence of adverse events and children under one year old were the most affected individuals. Conclusion: the current scenario is worrisome because these are preventable AEFI - injuring patients due to bad vaccination practices - that may undermine the population's confidence, reducing immunization coverage, and the progress in the control of vaccine-preventable diseases.

Abscesso subperiosteal com extensão epidural devido à rinossinusite aguda em criança de dez anos / Subperiosteal abscess with epidural extension due to acute rhinosinusitis in a ten-year-old child

RESUMO A rinossinusite aguda é uma das afecções mais prevalentes das vias aéreas superiores. Fatores anatômicos presentes em crianças e jovens propiciam o aparecimento de complicações orbitárias. Embora mais raras, as complicações intracranianas das rinossinusites perfazem um grau alto de letalidade, são mais comuns em pacientes acima de sete anos, e devem ser tratadas por uma equipe multidisciplinar.

ABSTRACT Acute rhinosinusitis is one of the most prevalent diseases of the upper airways. Anatomical factors present in children and young people allow for the onset of orbital complications. Although rare, intracranial complications of sinusitis account for a high degree of lethality, are more common in patients over the age of seven, and should be treated by a multidisciplinary team.

Perigastric Abscess as a Complication of Endoscopic Submucosal Dissection for Early Gastric Cancer: First Case Report / 대한소화기학회지

Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) is a widely accepted and well established procedure because of its curative potential and low invasiveness compared with surgery. Perforation is a potential major complication during ESD, and non-surgical treatments such as endoscopic closure with clips are sufficient in most cases. Here, we report a case of perigastric abscess that occurred as a complication of ESD for EGC. The patient improved with administration of antibiotics without surgical intervention.

Abordagem cirúrgica de abscesso orbitário subperiosteal associado à fratura de órbita / Surgical approach of orbitalsubperiosteal abscess associated with the orbital fracture

As cavidades orbitárias com os espaços aéreos da face e a ocorrência de infecções advindas de sinusites para a órbita são frequentes especialmente devido à proximidade. Acometem mais comumente crianças com estado nutricional debilitado. Clinicamente apresentam os sinais flogísticos, além de deficit visual, diplopia, oftalmoplegia e proptose. Podem evoluir com complicações graves, como trombose do seio cavernoso e abscesso intracraniano. Estas infecções podem ser classificadas de acordo com sua gravidade. Os exames de imagem de escolha para o diagnóstico e planejamento dos casos são cortes axiais e coronais de tomografia computadorizada. O tratamento deve ser compatível com a gravidade do caso e reação do organismo à antibioticoterapia. O objetivo deste artigo é relatar um caso clínico de paciente pediátrico que após trauma em face foi acometido por fratura em rebordo orbitário superior e desenvolveu posteriormente abscesso orbitário subperiosteal, discutindo os critérios clínicos e imaginológicos para o diagnóstico e a devida condução do caso.

The proximity of the orbital cavities to the air spaces of the face results in the occurrence of orbital infections resulting from sinusitis. Children with debilitated nutritional status are especially vulnerable. Clinically presents the inflammatory signs, and visual acuity deficit, diplopia, ophthalmoplegia and proptosis. Might also lead to severe complications such as cavernous sinus thrombosis and intracranial abscess. These infections can be classified according to their severity. Imaging tests of choice for the diagnosis and planning of cases include axial and coronal cuts of computed tomography. Treatment should be compatible with the severity of the case, taking into account the side effects of the antibiotics used. The objective of this paper is to report a case of a pediatric patient who sustained facial trauma resulting in fracture of the upper orbital rim and subsequently developed orbital subperiosteal abscess. We discuss the clinical and imaging criteria for successful diagnosis and treatment.

Conclusion: In every virginal female adolescent with a TAO, should be consider a mullerian anomaly in the differential diagnosis...

Evaluation of holmium laser for transurethral deroofing of severe and multiloculated prostatic abscesses

PURPOSE: Our objective was to evaluate the use of a holmium laser for transurethral deroofing of a prostatic abscess in patients with severe and multiloculated prostatic abscesses. MATERIALS AND METHODS: From January 2011 to April 2014, eight patients who were diagnosed with prostatic abscesses and who underwent transurethral holmium laser deroofing at Pusan National University Hospital were retrospectively reviewed. RESULTS: Multiloculated or multifocal abscess cavities were found on the preoperative computed tomography (CT) scan in all eight patients. All patients who underwent transurethral holmium laser deroofing of a prostatic abscess had successful outcomes, without the need for secondary surgery. Of the eight patients, seven underwent holmium laser enucleation of the prostate (HoLEP) for the removal of residual adenoma. Markedly reduced multiloculated abscess cavities were found in the follow-up CT in all patients. No prostatic abscess recurrence was found. Transient stress urinary incontinence was observed in three patients. The stress urinary incontinence subsided within 3 weeks in two patients and improved with conservative management within 2 months in the remaining patient. CONCLUSIONS: Transurethral holmium laser deroofing of prostatic abscesses ensures successful drainage of the entire abscess cavity. Because we resolved the predisposing conditions of prostatic abscess, such as bladder outlet obstruction and prostatic calcification, by simultaneously conducting HoLEP, there was no recurrence of the prostatic abscesses after surgery. We recommend our method in patients requiring transurethral drainage.

Relationship Between Uncommon Computed Tomography Findings and Clinical Aspects in Patients With Acute Pyelonephritis

PURPOSE: Computed tomography (CT) has become popular in the diagnosis of acute pyelonephritis (APN) and its related complications in adults. The aim of this study was to investigate the relationship between uncommon CT findings and clinical and laboratory data in patients with APN. MATERIALS AND METHODS: From July 2009 to July 2012, CT findings and clinical data were collected from 125 female patients with APN. The six uncommon CT findings (excluding a wedge-shaped area of hypoperfusion in the renal parenchyma) studied were perirenal fat infiltration, ureteral wall edema, renal abscess formation, pelvic ascites, periportal edema, and renal scarring. The clinical parameters analyzed were the age and body mass index of the patients as well as the degree and duration of fever. Laboratory parameters related to inflammation and infection included white blood cell count, C-reactive protein (CRP) level, erythrocyte sedimentation rate, pyuria, and bacteriuria. RESULTS: The most common CT finding was perirenal fat infiltration (69 cases, 55%). A longer duration of fever, higher CRP level, and grade of pyuria were related with perirenal fat infiltration (p=0.010, p=0.003, and p=0.049, respectively). The CRP level was significantly higher in patients with renal abscess and ureteral wall edema (p=0.005 and p=0.015, respectively). CONCLUSIONS: The uncommon CT findings that were related to aggravated clinical and laboratory parameters of APN patients were perirenal fat infiltration, ureteral wall edema, and renal abscess formation. The inflammatory reaction and tissue destruction may be more aggressive in patients with these CT findings.

OBJETIVO: Investigar as complicações orbitais em crianças e adultos com sinusite. MÉTODO: Os pacientes que frequentam clínica de Otorrinolaringologia com sinusite de janeiro de 2010 até janeiro de 2012 foram incluídos. Os pacientes foram classificados em dois grupos, de acordo com sua idade. O primeiro incluiu crianças idade inferior a 16 anos e, o segundo, pacientes com mais de 16 anos. Quadro clínico, seio envolvido, gestão e resultados foram comparados. RESULTADOS: O número total de pacientes foi 616. Complicações orbitais foram observadas em 36 pacientes (5,8%). Destes, 26 pacientes (72,2%) eram crianças (21 tinham presseptal e cinco tiveram celulite orbitária) e dez pacientes (27,8%) eram adultos (cinco com pré-septal, três com celulite orbitária e dois com abscesso). A complicação mais comum foi celulite orbital presseptal (72,2%), seguida de celulite e abcesso orbital (22,2% e 5,6%, respectivamente). O seio mais comum envolvido foi etmoidal em crianças e sinusopatia mista em adultos. A maioria dos pacientes respondeu ao tratamento médico. CONCLUSÃO: As complicações orbitárias da sinusite são mais comuns em crianças do que em adultos e têm prognóstico favorável. .

OBJECTIVE: To investigate orbital complications in children and adult with sinusitis. METHOD: Patients attending ENT clinic with sinusitis from January 2010 until January 2012 were included. Patients were classified into two groups according to their age. First involved children aged less than 16 and second included adults older than 16 years. Clinical picture, sinus involved, management and outcome were compared. RESULTS: The total number of patients were 616. Orbital complications were seen in 36 patients (5.8%). Twenty six patients (72.2%) were children (21 had preseptal and 5 had orbital cellulitis) and ten patients (27.8%) were adults (5 with preseptal, three with orbital cellulitis and 2 with abscess). The most common orbital complication was preseptal cellulitis (72.2%) followed by orbital cellulitis and abscess (22.2% and 5.6% respectively). The commonest sinus involved was ethmoidal in children and mixed sinus pathology in adults. The majority of patients responded to medical treatment. CONCLUSION: Orbital complications of sinusitis are commoner in children than adults and have favorable prognosis. Keywords: Sinusitis, cellulitis, preseptal, abscess. .

Extrapulmonary multidrug resistant tuberculosis presenting as chest wall abscess - A rare case report.

Summary: Even though the prevalence of pulmonary drug resistant tuberculosis is showing an increasing trend globally, only a few case reports of extrapulmonary tuberculosis caused by drug resistant mycobacteria have been documented over the last decade. Extrapulmonary tuberculosis is not infrequent and may cause considerable morbidity and mortality. Tuberculous abscess over chest wall is commonly due to the spread from an adjacent affected lymph node group. Multidrug resistance poses a great challenge to the physicians in managing such a condition and significantly affects the prognosis. Here we report a rare presentation of multidrug resistant tuberculosis as anterior chest wall abscess in a young male.
