Abscesos renales: experiencia en un hospital pediátrico de referencia / Renal abscesses: Experience at a referent Pediatric Hospital

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.

[Pediatric renal abscesses: a diagnostic challenge]. / Absceso renal en Pediatría: un desafío diagnóstico.

Kidney abscess is an unusual entity in childhood with few studies about its clinical characteris tics. OBJECTIVE: To report the clinical presentation, diagnosis, and therapy used in a cohort of 20 children with kidney abscess. PATIENTS AND METHOD: retrospective study of cases of kidney abscess during a 10-year period at the Hospital Roberto del Río. The analysis of clinical, laboratory, and imaging characteristics were evaluated as well as the treatment usedfor this condition. RESULTS: 20 cases were reported among which 65% were women with a median age of 3.6 years. The most com mon clinical presentation was fever, vomit, and dysuria. Eighty percent of patients presented an increase of inflammatory parameters, 88% presented positive urine culture, and the most common organism identified was Escherichia Coli (77.8%). The diagnosis was mostly made through kidney ultrasound (75%) followed by an abdominal CT scan (35%). 93% of abscesses were unilateral. About 95% of the patients only required antibiotic treatment. Vesicoureteral reflux was diagno sed in 28% of the patients with no sphincter control, and only one of them presented high-grade reflux. In patients with sphincter control, bladder and bowel dysfunction (BBD) was diagnosed in 90% of the cases. Forty four percent of the patients with late DMSA renal scintigraphy presented renal scarring. CONCLUSIONS: In this series, pediatric kidney abscess appears with persistent fever despite the treatment, requiring prolonged antibiotic therapy and rarely surgical drains. We su ggest a study aimed at detecting modifiable factors, such as vesicoureteral reflux in patients with no sphincter control and BBD in patients with sphincter control, as well as identifying renal paren chymal sequels in all patients.

Campylobacter fetus bacteremia complicated by multiple splenic abscesses and multivisceral signs in a renal transplant recipient: a case report and review of the literature.

We report a rare case of Campylobacter fetus bacteremia in a 50-year-old woman following kidney transplantation. Bacteremia was complicated by multivisceral signs such as multiple splenic abscesses, bacterial hepatitis, erythema nodosum and reactive arthritis. Despite a prolonged diagnostic delay, the diagnosis was made on blood culture identification and the global outcome was favorable with adequate antibiotherapy. Reports in the literature describe a high rate of mortality for Campylobacter spp. septicemia, with most patients being immunocompromised. However, Campylobacter spp. has been rarely described in renal transplant patients. Moreover, a splenic septic localization due to Campylobacter spp. has been reported only once to our knowledge. Clinicians should be aware of the diagnostic difficulties related to the frequent negativity of stool samples in C. fetus septicemia, in order to implement a tailored medical strategy. Some data suggest that rapid introduction of adapted antibiotic therapy is associated with a reduction in mortality.

A Periorbital Abscess with Combined Retinal Artery Occlusion and Retinal Vein Occlusion: A Case Report.

BACKGROUND Periorbital abscesses are uncommon complications of acute bacterial rhinosinusitis; with the evolution of diagnostic and therapeutic methods, it is rare that the patient progresses to irreversible blindness. Central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) rarely occur simultaneously and the factors that influence this occurrence are not well understood. CASE REPORT This is a case report of an immunocompetent healthy adolescent girl, who developed irreversible blindness caused by a periorbital abscess secondary to acute bacterial rhinosinusitis due to CRAO and CRVO. Despite 6 days of clinical treatment, including intravenous antibiotics (vancomycin-associated piperacillin with tazobactam), she had a large periorbital abscess and could not open her left eye. Therefore, she was transferred to a tertiary hospital; 1 day after her admission, she underwent surgical treatment to drain the abscess through external and endoscopic access. In addition, she received broad-spectrum antibiotics (meropenem with vancomycin) for 3 weeks. She was no longer able to perceive light with the left eye, despite her clinical improvement. This case report discusses the factors that could have contributed to this poor outcome, despite clinical and surgical treatment. CONCLUSIONS We conclude that there are several mechanisms that can lead to the loss of vision and when the indicated surgical intervention is delayed, it can increase the risk of visual sequelae.

Absceso periostomal secundario a perforación intestinal por cuerpo extraño: presentación de un caso / Periostomal abscess secondary to bowel perforation due to foreign body ingestion: a case report

Resumen Objetivo: Reportar un caso de absceso periostomal, su diagnóstico clínico e imagenológico y manejo. Materiales y Método: Paciente de 77 años usuaria de colostomía con dolor abdominal asociado a aumento de volumen y enrojecimiento de la piel alrededor de la colostomía. Una tomografía computada de abdomen muestra un cuerpo extraño perforante de la pared colónica ostomizada, asociado a formación de un absceso. Resultados: Se practica una incisión de la colección, dando salida a gran cantidad de pus y cuerpo extraño correspondiente a tibia de ave. Se inicia cobertura antibiótica y se instala drenaje Penrose. Controles posteriores muestran regresión del absceso y drenaje sin débito. Discusión: 80%-90% de los cuerpos extraños ingeridos son eliminados sin complicación y < 1% producen perforación. Esto es más común en segmentos intestinales angulados o intervenidos quirúrgicamente. La clínica es inespecífica y el diagnóstico requiere una imagen que identifique signos sugerentes. Conclusión: Un absceso periostomal y la perforación intestinal por cuerpo extraño son cuadros infrecuentes. La alta sospecha diagnóstica y una evaluación imagenológica pueden dar una respuesta precisa. Además del manejo quirúrgico, debe asociarse cobertura antibiótica para enteropatógenos y generalmente un sistema de drenaje.

Aim: To report a case of periostomal abscess, its clinical and imaging diagnosis and management. Materials and Method: 77-year-old patient, user of a colostomy with abdominal pain associated to swelling and redness of the skin next to the colostomy. A computed tomography of the abdomen showed a foreign body perforating the ostomized bowel associated to the formation of an abscess. Results: An incision of the gathering was performed, giving out a great quantity of pus and the foreign body, which corresponded to a bird's tibia. Antibiotic therapy was given, and a Penrose drainage installed. Further controls showed regression of the abscess and no flux from drainage. Discussion: 80%-90% of ingested foreign bodies are eliminated without complications and < 1% produce perforation. This is more common in angled intestinal segments or surgically intervened ones. Clinical features are unspecific, and diagnosis requires suggesting imaging signs. Conclusion: Periostomal abscesses and bowel perforation due to foreign body are infrequent. High diagnostic suspicion and an imaging evaluation may give a precise answer. Besides surgical management, antibiotic coverage for enteropathogens must be associated and a drainage system too in most cases.

Safety of Allogeneic Adipose Tissue-Derived Mesenchymal Stem Cells for the Treatment of Complex Perianal Fistulas Not Associated With Crohn's Disease: A Phase I Clinical Trial.

BACKGROUND: Anal fistula treatment aims to eradicate the fistula, preserve the sphincter, prevent recurrence, and allow an early return to daily activities for the patient. Because of the difficulty of achieving these goals, stem cell-based therapy has emerged for the treatment of complex perianal fistula with promising results. OBJECTIVE: The objective of this study was to evaluate the safety of allogeneic mesenchymal stem cells in the treatment of complex anal fistula in patients without Crohn's disease. DESIGN: This was a prospective nonrandomized phase I clinical trial. SETTINGS: This study was conducted at a second-level hospital. PATIENTS: Twenty consecutive patients diagnosed with a complex fistula were included. INTERVENTIONS: All patients received 40 × 106 allogeneic mesenchymal stem cells. In patients with 2 tracts, 20 × 106 stem cells were applied on each tract. MAIN OUTCOME MEASURES: The patients were discharged 24 hours after the procedure and were evaluated at 1, 2, 4, 8, 16, and 24 weeks after the application. The long-term follow-up was performed 1 year after the procedure. RESULTS: The procedure was performed in a total of 20 patients from October 1, 2016, to October 31, 2017; 1 patient was eliminated from the final data analysis. No adverse effects were reported within the first 24 hours, and all the patients were discharged asymptomatic. Three patients (15%) presented with perianal abscess. In 1 patient, the abscess appeared at the fourth week, and, in the other 2 patients, the abscess was diagnosed at week 8. Complete closure was achieved in 13 (69%) patients. LIMITATIONS: This was a nonrandomized controlled trial. CONCLUSION: The use of allogeneic mesenchymal stem cells as a treatment is a safe option for the management of complex perianal fistula not associated with Crohn's disease.

Absceso de Brodie, una patología de difícil diagnóstico / Brodie's abscess, a pathology difficult to diagnose

INTRODUCCIÓN: Las infecciones osteoarticulares agudas pediátricas constituyen patologías poco frecuentes, siendo de suma importancia realizar un diagnóstico precoz y tratamiento adecuado para evitar las compli caciones agudas o a largo plazo. El absceso de Brodie (AB) es una forma de osteomielitis subaguda de baja incidencia y de difícil diagnóstico, por lo que es imprescindible la sospecha clínica. OBJETIVO: Presentar un caso de AB y describir las características etiológicas y clínicas de esta patología. CASO CLÍNICO: Paciente 14 años, evaluado por dolor de muslo derecho de un mes de evolución, afebril y sin antecedente de trauma. Al examen físico no presentaba aumento de volumen, el rango de movimiento (ROM) de cadera derecha era doloroso y la sensibilidad estaba aumentada a la palpación su perficial de banda iliotibial (BIT) derecha. Estudio radiológico sin alteraciones. Por persistir síntomas se solicitó ecografía de muslo que mostró irregularidad ósea cortical. Resonancia Magnética (RM) evidenció lesión en diáfisis de fémur derecho de probable origen tumoral o infeccioso. Parámetros inflamatorios sin alteraciones. Se realizó toma de biopsia y cultivos, aislando Staphylococcus aureus multisensible. Se procedió a aseo quirúrgico y terapia antibiótica endovenosa, evolucionando favo rablemente. CONCLUSIONES: La presentación clínica y laboratorio en AB pueden ser inespecíficas. El clínico no especialista debe tener un alto índice de sospecha de esta patología como posible diagnós tico diferencial en pacientes que persisten con dolor y presentan una alteración radiológica, incluso ante la ausencia de otros síntomas y parámetros inflamatorios normales. Es importante realizar una biopsia ósea para el diagnóstico diferencial de patologías tumorales.

INTRODUCTION: Acute osteoarticular infections in children are rare pathologies, therefore early diagnosis and prompt treatment are crucial to avoid acute and long-term complications. Brodie's abscess (BA) is an un common type of subacute osteomyelitis, difficult to diagnose, so clinical suspicion is essential. OBJECTIVE: To describe a case of Brodie's abscess and its etiological and clinical features. CLINICAL CASE: A 14-year-old patient was seen at our clinic, who reported a one-month pain in the right thigh, with no history of fever or trauma. Physical examination revealed no volume increase, painful right hip range of motion, and increased sensitivity on superficial palpation of the right iliotibial band. X-rays where normal. Because of the pain persistence, an ultrasound was requested which showed a cortical irregularity. Magnetic resonance imaging (MRI) was performed and revealed a right femoral diaphysis, due to a possible bone tumor or an infectious process. Lab tests were normal. Biopsy and cultures were collected, identifying multi-sensitive Staphylococcus aureus. He was managed with debridement and intravenous antibiotics, responding positively. CONCLUSIONS: The BA's clinical features and lab tests are unspecific, therefore the non-specialist physician should strongly suspect this pathology as a possible differential diagnosis in patients who persist with pain and present imaging alterations, even when there are no other symptoms or normal inflammatory parameters. A bone biopsy is essential for the differential diagnosis of tumor pathologies.

Unusual case of lagochilascariasis with breast involvement: the first case report in pregnancy.

Lagochilascariasis is a neglected neotropical helminthiasis, responsible for human infections through the ingestion of raw or undercooked meat from wild animals infected by larvae encysted in their tissues. It is characterized by a chronic evolution with periods of remission and recurrences, affecting mainly the head and neck regions. It can progress to death by invasion of the central nervous system. It is caused by the Lagochilascaris minor nematode, first described in 1909 and mainly found in the Brazilian Amazon ecosystem, notably in Para State. In May 2010, a 15-year-old female, born in the city of Aveiro, Para State, was hospitalized in the city of Santarem, Para State, presenting with cervical and spinal abscesses and osteolytic lesions at T3-T5 level. During hospitalization, white larvae identified as L. minor were observed in a cervical subcutaneous fistula. After the surgical drainage of abscesses, albendazole 400 mg/day was started, with improvement of symptoms. The patient abandoned the follow-up and in January 2016, during the 20th week of pregnancy, she was readmitted to the Santarem Municipal Hospital with new cervical abscesses in the infra-mammary region, with numerous larvae exiting by subcutaneous left breast fistulas. The antiparasitic treatment was restarted due to possible reactivation of the infection in the spine and dissemination to the central nervous system. Ten weeks after hospital discharge, the patient had resolution of the fistulas and decreased abscesses, without gestational complications. This is the first case report of lagochilascariasis during pregnancy, as well as of involvement of mammary glands.

Anal abscess microbiology as an anal fistula predictor / Microbiologia de abscesso anal como preditivo de fístula anal

ABSTRACT In order to determine the microbiology of anal abscess as a predictor of anal fistulas in patients who attended the external consultation of the Coloproctology unit of the Dr. Antonio María Pineda University Central Hospital, a prospective, descriptive, longitudinal study was conducted from September 2018 to July 2019. In this study, the population consisted of patients with a diagnosis of anal abscess, without associated comorbidities or contraindications for surgery, who agreed to be included in the study. A non-probabilistic, intentional sample consisting of 42 patients was determined. An appointment-based study protocol was applied by outpatient for patients who met the inclusion criteria applied, to perform due medical history through anamnesis, physical examination and culture taking of suppuration from the anal abscess to subsequently establish medical and surgical behavior thereof. The results were expressed in absolute numbers and percentages, a prevalence of ischiorectal abscesses was observed, followed by deep post-anal space abscesses. Anaerobic bacteria were isolated in 100% of the sample. In all fistulized patients, E. Coli was isolated as a predominant germ.

RESUMO Um estudo prospectivo, descritivo e longitudinal foi realizado de setembro de 2018 a Julho 2019 para determinar a microbiologia do abscesso anal como preditivo de fístulas anais em pacientes que compareceram à consulta externa da unidade de Coloproctologia do Hospital Central da Universidade Dr. Antonio María Pineda. Neste estudo, a população foi composta por pacientes com diagnóstico de abscesso anal, sem comorbidades ou contraindicações associadas à cirurgia, que concordaram em participar do estudo. Uma amostra intencional não probabilística, composta por 42 pacientes foi determinada. Um protocolo de estudo com base na consulta em regime ambulatorial foi aplicado aos pacientes que atenderam os critérios de inclusão estabelecidos, para realizar a anamnese, o exame físico e a devida cultura da supuração do abscesso anal para posteriormente estabelecer o comportamento médico e cirúrgico. Os resultados foram expressos em números absolutos e porcentagens, observando-se a prevalência de abscessos isquiorretais, seguidos por abscessos profundos no espaço pós-anal. Bactérias anaeróbias foram isoladas em 100% das amostras. Em todos os pacientes com fístulas, E. Coli foi isolada como um germe predominante.

Unusual abscess masquerading as poorly differentiated adenocarcinoma of the colon showing characteristics of choriocarcinoma

Extragonadal non-gestational choriocarcinoma (ENC) is an uncommon malignant tumor occasionally found in the gastrointestinal tract. ENC is characterized by a biphasic tumor growth with distinct areas of adenocarcinoma and choriocarcinoma differentiation. Primary choriocarcinoma of the colon is extremely rare, with only 21 cases reported in the literature. Most of the perforation of colorectal cancers occurs in the abdominal cavity, while abdominal wall abscess is rare; the psoas abscess associated with colon carcinoma is even less observed. Herein, we report the case of a 61-year-old female with poorly differentiated adenocarcinoma of the ascending colon and sigmoid, with choriocarcinomatous differentiation, masquerading a psoas abscess formation. Unfortunately, despite the aggressive therapy, the patient's disease rapidly progressed, and she died within 2 months after the diagnosis. The typical morphological pattern, immunohistochemistry, and its correlation with serum β-human chorionic gonadotropin enabled a correct diagnosis.

Subphrenic abscess secondary to cervical abscess and fasciitis from dental focus: case report.

BACKGROUND: Cervical fasciitis is a group of severe infections with high morbimortality. Reports in the literature of patients with cases evolving with mediastinal dissemination of deep cervical abscess are common. However, cases of abdominal dissemination by contiguity are much rarer. CASE PRESENTATION: A 34-year-old Caucasian man presented to the emergency department with a 15-day history of left neck edema, local pain, and fever. Seventeen days prior to presentation, he had undergone odontogenic surgical treatment in a dental clinic. Laboratory examinations did not show meaningful changes. He underwent computed tomography of the neck, thorax, and abdomen, which showed evidence of left collection affecting the retromandibular, submandibular, parapharyngeal, vascular, and mediastinal spaces, bilateral pleural effusion, right subphrenic collection and a small amount of liquids between intestinal loops. A cervical, thoracic, and abdominal surgical approach at the same surgery was indicated for odontogenic cervical abscess, descending necrotizing mediastinitis, and subphrenic abscess. The patient remained in the intensive care unit for three days, and he was discharged on the 22nd day after surgery with no drains and no tracheostomy. His outpatient discharge occurred after 6 months with no sequelae. CONCLUSIONS: Aggressive surgical treatment associated with antibiotic therapy has been shown to be effective for improving the clinical course of cervical fasciitis. Despite the extension of the infection in our patient, a surgical approach of all infectious focus associated with a broad-spectrum antibiotic therapy led to a good clinical evolution and has significant implications for aggressive treatment.

Abscesos profundos de cuello en pediatría: experiencia del Hospital Dr. Sótero del Río entre los años 2011 y 2018 / Pediatric deep neck abscesses: Dr. Sótero del Río Hospital 2011-2018 experience

RESUMEN Introducción: Los abscesos profundos de cuello son colecciones de pus alojadas en los espacios profundos cervicales. En la población pediátrica son poco frecuentes, sin embargo, pueden presentar complicaciones potencialmente mortales. Objetivo: Caracterizar a los pacientes que consultan por abscesos profundos del cuello en el Servicio de Urgencia Pediátrico del Hospital Dr. Sótero del Rio. Material y método: Estudio de tipo descriptivo retrospectivo con datos obtenidos de fichas clínicas de pacientes. Se realizó una revisión de fichas clínicas de los pacientes diagnosticados con abscesos profundos de cuello en el Servicio de Urgencia Pediátrica del Hospital Sótero del Río entre los años 2011 y 2018. Se analizaron variables clínicas (anamnesis, examen físico, exámenes de laboratorio generales y específicos y su manejo) y demográficas. Los resultados se analizaron mediante estadística descriptiva con medidas de tendencia central y rango, utilizando Statistical Package for the Social Science (SPSS). Resultados: Se incluyeron 41 pacientes entre 0 y 15 años, con un promedio de edad de 7,2 años. Sesenta y tres por ciento de los pacientes fueron de sexo masculino. Se presentaron 23 (56%) pacientes con abscesos periamigdalinos (PA), 12 (29,2%) con abscesos retrofaríngeos (RF), 5 (12,1%) con abscesos parafaríngeos (PF) y 1 (2,4%) con absceso de tipo mixto (RF- PF). El 60% de los pacientes recibió algún tratamiento médico previo. Se realizó estudio imagenológico en 83% de los pacientes. Todos los pacientes presentaron parámetros inflamatorios elevados. En el 80% de los pacientes se realizó tratamiento médico y algún tipo de drenaje. Conclusiones: Los abscesos profundos del cuello son una entidad relativamente poco frecuente en pediatría, pero potencialmente peligrosa si no se detecta a tiempo, por lo que debemos tener un alto índice de sospecha para evitar las complicaciones.

ABSTRACT Introduction: Deep neck abscesses are pus collections lodged in the deep cervical spaces. They are rare in the pediatric population, however, they can present life-threatening complications. Objective: To characterize the patients who consult for deep neck abscesses in the pediatric emergency department of Dr. Sótero del Rio Hospital. Material and method: Descriptive retrospective study. A review of clinical records of patients diagnosed with deep neck abscesses in the pediatric emergency department of Dr. Sótero del Rio Hospital between 2011 and 2018 was made. The clinical (anamnesis, physical exam, general and specific laboratory exams and management) and demographic characteristics were evaluated. The results were analyzed by descriptive statistics with measures of central tendency and range, using Statistical Package for the Social Science (SPSS). Results: Forty-one patients between 0 and 15 years of age were included, with an average age of 7.2 years. 63% of the patients were male. There were 23 (56%) patients with peritonsillar abscesses (PA), 12 (29.2%) with retropharyngeal abscesses (RF), 5 (12.1%) with parapharyngeal abscesses (PF) and 1 (2.4%) with abscess of mixed type (RF-PF). 60% of the patients received some previous medical treatment. An imaging study was performed in 83% of the patients. All the patients presented high inflammatory parameters. In 80% of patients, medical treatment and some type of drainage were performed. Conclusions: Deep abscesses of the neck are a relatively rare entity in pediatrics, but potentially dangerous if not detected in time, so we must have a high index of suspicion to avoid complications.

Absceso óseo en un paciente joven con artritis reumatoide, a propósito de un caso / Bone abscess in a young patient with rheumatoid arthritis, about a case

Introducción: la artritis reumatoide es una enfermedad inflamatoria sistémica y crónica que se caracteriza fundamentalmente por la presencia de dolor, inflamación, deformidad, discapacidad y disminución de la percepción de calidad de vida relacionada con la salud. El propio mecanismo etiopatogénico de la enfermedad y la acción de los fármacos utilizados en su control generan un estado de inmunosupresión que puede ocasionar la proliferación de bacterias y la aparición posterior de abscesos a distintos niveles. Objetivo: dar a conocer los elementos clínicos, de laboratorio e imagenológicos que permiten llegar al diagnóstico de un absceso óseo en un paciente con artritis reumatoide. Caso clínico: se presenta el caso de un paciente masculino, de 31 años de edad con diagnóstico de artritis reumatoide de 7 años de evolución que acude a consulta con manifestaciones clínicas, de laboratorio e imagenológicos que permiten llegar al diagnóstico de un absceso óseo. Conclusiones: los procesos infecciosos óseos constituyen un factor agravante de la calidad ósea, si los mismos se presentan en pacientes con enfermedades reumáticas como la artritis reumatoide, donde existen distintos niveles de afectación ósea, entonces se compromete más aún la salud y funcionamiento articular(AU)

Introduction: rheumatoid arthritis is a systemic and chronic inflammatory disease characterized mainly by the presence of pain, inflammation, deformity, disability and decreased perception of quality of life related to health. The own etiopathogenic mechanism of the disease and the action of the drugs used in its control generate a state of immunosuppression that can cause the proliferation of bacteria and the subsequent appearance of abscesses at different levels. Objective: to present the clinical, laboratory and imaging elements that allow us to reach the diagnosis of a bone abscess in a patient with rheumatoid arthritis. Clinical case: we present the case of a 31-year-old male patient with a 7-year history of rheumatoid arthritis who presented with clinical, laboratory and imaging findings that allow the diagnosis of a bone abscess. Conclusions: bone infectious processes are an aggravating factor of bone quality, if they occur in patients with rheumatic diseases such as rheumatoid arthritis, where there are different levels of bone involvement, then health and joint function are more compromised(AU)

Intramedullary cervical abscess mimicking a spinal cord tumor in a 10-year-old girl: a case-based review.

BACKGROUND: Intramedullary spinal cord abscesses (ISCA) are a rare pathological entity with very few cases reported in the world and may be confused with an intramedullary tumor. Cervical location is the least frequently affected, except for cryptogenic spread, mostly seen in adult patients. Meticulous study of contrast-enhanced MRI pictures has a key role in the diagnosis. METHOD AND RESULTS: We present a case of a spontaneous cervical ISCA, mimicking a spinal cord tumor, in a pediatric patient with good outcome. A review of the literature shows that this is a life-threatening condition with high chances of rupture and subsequent meningitis. CONCLUSIONS: We point out that if a solitary cervical spinal cord lesion is surrounded by significant medullar edema associated with fast onset of symptoms, fever, and elevation of WBC, the possibility of a spinal cord abscess should be considered prior to surgery.

Incidentally detected tuberculous prostatitis with microabscess

ABSTRACT Tuberculous prostatitis is a rare and often overlooked entity that may mimic prostatic adenocarcinoma on imaging exams, especially multiparametric magnetic resonance imaging (MRI) of the prostate. Detection of a prostatic abscess is a clue to the correct diagnosis.

Absceso subpectoral como diagnóstico diferencial de hombro doloroso: reporte de un caso / Subpectoral abscess as a differential diagnosis of painful shoulder: a case report

Los síndromes dolorosos del hombro son relativamente comunes en la práctica clínica. Habitualmente son causados por un número limitado de patologías. Dentro de los diagnósticos diferenciales, el pinzamiento subacromial, las lesiones aisladas del manguito rotador, capsulitis adhesiva, tendinitis cálcica, patología degenerativa de las articulaciones glenohumeral y acromioclavicular, y la inestabilidad crónica del hombro, son causas comunes. Causas infrecuentes son la rotura del tendón del bíceps, neuralgias, patología infecciosa articular y tumores del hombro. Un absceso subpectoral sin sintomatología infecciosa clara es una causa extremadamente rara de hombro doloroso en el adulto. Presentamos el caso de un paciente de 60 años, que inicia con un cuadro de hombro doloroso cuya causa se identifica como un absceso subpectoral por staphylococcus aureus que se maneja con drenaje quirúrgico y tratamiento antibiótico endovenoso con buenos resultados.

Painful shoulder syndromes are commonly caused by a limited assortment of pathologies. Differential diagnosis include rotator cuff impingement syndrome, rotator cuff tears, adhesive capsulitis, calcific tendonitis, degenerative disease of the joint including acromio-clavicular and gleno-humeral joints and chronic instability. Less common causes are labral tears, biceps tendon rupture, soft tissue infection, neurologic disease, joint infection and shoulder tumors. A subpectoral abscess without infectious clinical features is a very rare cause of shoulder pain in adults. We present the case of a 52 years old male who develops a painful shoulder syndrome caused by a staphylococcus aureus subpectoral abscess, treated by surgical drainage and intravenous antibiotic therapy with good results.
