Introducción: El absceso epidural espinal piógeno es la localización de una colección infecciosa dentro del canal raquídeo, por fuera del saco dural. El diagnóstico es difícil y las consecuencias son devastadoras a causa de la compresión o el compromiso vascular. La resonancia magnética tiene una alta sensibilidad y especificidad diagnósticas que aumentan si se administra un medio de contraste. Los objetivos de este estudio fueron: determinar la reproducibilidad inter- e intraobservador, y discriminar los distintos parámetros y diferencias entre especialidades. Materiales y Métodos: Veintisiete observadores independientes evaluaron 5 parámetros: región, ubicación, compromiso, asociación y perivertebral, absceso extravertebral anterior, lateral o posterior. Se analizaron 35 casos en tres oportunidades, se utilizó el coeficiente kappa. Resultados: El nivel de acuerdo global intra- e interobservador global fue kappa 0,76; los valores obtenidos fueron: región 0,94; ubicación 0,88; compromiso 0,55; asociación 0,67 y perivertebral 0,77. Los tres primeros parámetros dan noción de volumen y los dos últimos reflejan la presencia de focos infecciosos vertebrales por fuera del conducto. Conclusiones: La clasificación morfológica propuesta es de uso simple y tiene una muy buena tasa de reproducibilidad intra- e interobservador. Los parámetros con mayor reproducibilidad son: región y ubicación (>0,87).

BACKGROUND: Streptococcus intermedius together with S. anginosus and S. constellatus form the group S. anginosus (previously called S. milleri), anteriorly considered a type of S. viridans. Sometimes they can cause infections with a tendency to abscess at the liver and brain, but it is rare to find it as an etiologic agent of endocarditis, spondylodiscitis and epidural abscess. Therefore, the coexistence of the three locations is exceptional. CLINICAL CASE: A 72-year-old male patient was hospitalized because of decreased level of consciousness with aphasia. The patient reported low back pain with mechanical characteristics. During the first day, he presented a feverish peak and blood cultures were extracted in which Streptococcus intermedius grew. On lumbar spine MRI, spondylodiscitis was reported on L4-L5 and abscess in the anterior epidural space at the L5 level. A transesophageal echocardiogram was also performed, which showed two warts in the aortic and mitral valves. It was decided to give surgical treatment with valve replacement with a metallic mitral prosthesis. The epidural abscess was cured after antibiotic treatment. CONCLUSIONS: In a patient with S. intermedius endocarditis, the aggressiveness of the germ and the tendency to form abscesses in different locations must be taken into account. The presence of low back pain forces to rule out spondylodiscitis and an epidural abscess. [ABSTRACT FROM AUTHOR]

Introducción: La parálisis diafragmática unilateral (PDU) suele ser subclínica y hallarse fortuitamente en una radiografía (Rx) anteroposterior de tórax, en sujetos que suelen referir sólo disnea ante esfuerzos. La misma puede deberse a la lesión de un nervio frénico, pudiendo ser generada en una cirugía de cabeza y cuello. El objetivo del presente trabajo es describir la evaluación respiratoria de un sujeto con sospecha de PDU post-quirúrgica. Presentación del caso: Sujeto masculino de 34 años que ingresa derivado de otra institución con diagnóstico de síndrome medular incompleto secundario a absceso prevertebral cervical, el cual fue removido quirúrgicamente. Durante su rehabilitación en la unidad de cuidados intermedios presentó un cuadro clínico respiratorio, requiriendo de diversos estudios valorados por el servicio de kinesiología. Se evaluaron: Rx de tórax; radioscopía con sniff nasal; ecografía diafragmática; presiones estáticas máximas; capacidad vital y pico flujo tosido. Los resultados constataron el diagnóstico de PDU derecha post quirúrgica. Conclusión: Se ha descrito la evaluación respiratoria llevada a cabo en un sujeto con antecedente de remoción quirúrgica de absceso prevertebral cervical, la cual permitió arribar al diagnóstico de PDU derecha. En este caso fue fundamental el trabajo interdisciplinario, así como el rol del kinesiólogo como segunda barrera diagnóstica.

Epidural abscess is a rare but devastating condition, when is recognized and treated early the outcome is adequate. The review of the risk factors, pathogenesis, clinical features and outcome of this condition is appropriate, the aim being to make recommendations on anesthetic practice to minimize the risk of this serious complication.

The epidural abscess is a collection of pus in a space, it is presented in five people per 10,000, it is a medical emergency because of the potential risk of spinal cord compression and enables the progression of a irreversible motor defect to cause ischemia or thrombosis of nutritive vessels core. It is presented a male patient of 24 years old, white of urban origin, with a history of apparent health, two months before admission he presented boil in his left elbow and then began with a corresponding picture to the syndrome ponytail. Imaging studies showed the presence of a spinal epidural abscess that was treated with antibiotics and surgery; his evolution was satisfactory.

Spinal epidural abscess is a rare complication, it can be cause a high morbimortality and the prompt diagnosis and treatment is essential. Our patient present an abscess after epidural block for caesarean section, the anesthetic procedure was in aseptic technique and the catheter was withdrawn after surgery, the patient was discharged after 48 hours. She was readmitted nine days later with fever, left leg pain and wound surgery infection. The magnetic resonance showed a spinal epidural abscess in L3-L4. Underwent laminectomy cultured showed Escherichia coli, she was at hospital by intravenous antibiotic treatment for 4 weeks and she was discharged without neurologic sequelae. [ABSTRACT FROM AUTHOR]

Introducción: la osteomielitis tuberculosa del cráneo es una entidad rara y sólo ocurre en el 0,01 % de los pacientes con infección por Mycobacterium Tuberculosis, aunque esta frecuencia de presentación se incrementa notablemente en las personas portadoras de algún grado de inmunodeficiencia. El cuadro clínico suele ser de inicio insidioso y caracterizarse por la presencia de dolor local de intensidad progresiva. Objetivo: presentar un caso clínico poco frecuente con osteomielitis crónica de la bóveda craneal, secundaria a infección por Mycobacterium Tuberculoso. Presentación del caso: paciente de 5 años de edad con historia de dolor y aumento de volumen de la región interparietal del cráneo. Al examen físico se constató aumento de volumen con fluctuación de dicha región y defecto óseo irregular. Se realizó Rayos x de cráneo donde se pudo observar una lesión osteolítica de la bóveda craneal. Se practicó exéresis del hueso. En la recuperación post operatoria, se utilizaron durante las 2 primeras semanas la vancomicina y el ceftriaxone. La evolución clínica no fue satisfactoria, hasta que se obtuvo un cultivo positivo de Mycobacterium Tuberculoso, momento en que se comenzó tratamiento específico antituberculoso. El paciente evolucionó favorablemente después de cinco semanas del diagnóstico inicial. Conclusiones: la osteomielitis tuberculosa de la bóveda craneal aunque es poco frecuente puede verse, sobre todo, en países con una alta prevalencia de la enfermedad. Su diagnóstico y tratamiento oportuno pueden evitar complicaciones intracraneales.Background: tubercular osteomielitis of the skull is a rare entity that only occurs in the 0.01 % of patients infected by Mycobacterium Tuberculosis, although this frequency of presentation increases significantly in people who are carriers of some degree of immunodeficiency. The clinical picture is usually insidious at the onset of the disease and is characterized by the presence of local pain of progressive intensity. Objective: to present a less frequent clinical case of chronic osteomielitis of the skull secondary to an infection by Mycobacterium Tuberculosis. Case presentation: 5 years old patient with history of pain and increase in the volume of the interparietal region of the skull. On physical examination, an increase in the volume with fluctuation of the mentioned region and irregular bone defect was stated. A skull X-ray was ordered which revealed an osteolitic lesion of the skull. An exeresis of the bone was performed. Vancomicin and Ceftriaxone were used during the two first weeks of the postoperative recovery. The clinical evolution was not satisfactory until a positive culture of Mycobacterium Tuberculosis was obtained. Then, specific treatment for tuberculosis was indicated. The patient's evolution was favourable five weeks after the initial diagnosis. Conclusions: osteomielitis of the skull is rare, but can be seen, especially, in countries with high prevalence of the disease. Its early diagnosis and treatment can avoid intracranial complications.

A piomiosite é uma infecção muscular profunda subaguda que pode originar abscessos intramusculares únicos ou múltiplos. Está associada a infecções sistêmicas, diabetes mellitus, terapia imunossupressora, AIDS e mieloma múltiplo. Descrevemos um caso de piomiosite tropical com acometimento da coluna vertebral que evoluiu para abscesso epidural, em paciente com história pregressa de espondilite anquilosante em tratamento com medicações imunossupressoras e apresentou trauma direto na coxa direita previamente ao início dos sintomas. O objetivo deste trabalho é descrever o acometimento raro da coluna vertebral em pacientes com piomiosite tropical, com apenas um caso descrito na literatura mundial, destacando a necessidade dos métodos complementares na investigação diagnóstica para o adequado tratamento e as possíveis complicações dessa doença. Os pacientes imunossuprimidos com dores musculares subagudas devem ser investigados quanto à piomiosite tropical e o diagnóstico precoce é fundamental para o sucesso do tratamento.La piomiositis es una infección muscular profunda y subaguda que puede originar abscesos intramusculares únicos o múltiples.

Pott's puffy tumor is a rare complication of frontal sinusitis characterized by swelling and edema in the brow due to a subperiosteal abscess associated with frontal osteomyelitis. Added complications are cellulitis by extension to the orbit and intracranial infection by posterior extension, with high risk of meningitis, intracranial abscess, and venous sinus thrombosis. Early diagnosis and aggressive medical or surgical treatment are essential for optimal recovery of affected patients. In the antibiotic age it is extremely rare, with very few cases described in the recent literature. A case is presented of a Pott inflammatory tumor in a 7 year-old boy, as a complication of acute pansinusitis who presented with front preseptal swelling and intracranial involvement with thrombosis of ophthalmic and superior orbital veins and frontal epidural abscess extending to the subarachnoid space., (Copyright © 2013 Asociación Española de Pediatría.
