Gas surrounding the urinary bladder in emphysematous cystitis

ABSTRACT We report a rare case of emphysematous cystitis in a 66-year-old woman with a history of diabetes mellitus. The predisposition of diabetes mellitus and infection of gas-forming bacteria is considered to precede the manifestation of emphysematous cystitis. The present recommended diagnosis test is computed tomography, which have definite value in the evaluation of gas accumulation in bladder wall, or an air-fluid level in bladder.

Caso clínico: cistitis enfisematosa asociada a hidronefrosis secundaria / Emphysematous cystitis: Report of one case

We report a 53 year-old woman with type 2 diabetes mellitus and hypertension, presenting with progressive abdominal pain lasting three weeks, associated with lower abdominal swelling and fever. Clinical examination showed a large increase in abdominal volume, contraction of extracellular compartment, and signs of severe sepsis. Computed tomography showed an over-distended bladder with severe wall and luminal pneumatosis and bilateral hydronephrosis. The diagnosis was of emphysematous cystitis associated to hydronephrosis. Urine and blood cultures were positive for multi-susceptible Escherichia coli. Clinical evolution was favorable after 6 weeks of ceftriaxone and urinary catheter use. Emphysematous cystitis is a rare clinical entity, with an associated mortality of 7%. Known predisposing factors are older age, female gender and presence of diabetes. Microbiological agents most frequently involved are Escherichia coli and Klebsiella pneumoniae (80% of cases). Medical treatment is preferred and is based on urinary tract decompression with a bladder catheter, and prolonged broad spectrum antimicrobial therapy.

Pneumomediastinum, subcutaneous emphysema, and pneumothorax after a pulmonary function testing in a patient with bleomycin-induced interstitial pneumonitis / Pneumomediastino, enfisema subcutâneo e pneumotórax após prova de função pulmonar em paciente com pneumopatia intersticial por bleomicina

Spontaneous pneumomediastinum is an uncommon event, the clinical picture of which includes retrosternal chest pain, subcutaneous emphysema, dyspnea, and dysphonia. The pathophysiological mechanism involved is the emergence of a pressure gradient between the alveoli and surrounding structures, causing alveolar rupture with subsequent dissection of the peribronchovascular sheath and infiltration of the mediastinum and subcutaneous tissue with air. Known triggers include acute exacerbations of asthma and situations that require the Valsalva maneuver. We described and documented with HRCT scans the occurrence of pneumomediastinum after a patient with bleomycin-induced interstitial lung disease underwent pulmonary function testing. Although uncommon, the association between pulmonary function testing and air leak syndromes has been increasingly reported in the literature, and lung diseases, such as interstitial lung diseases, include structural changes that facilitate the occurrence of this complication.

O pneumomediastino espontâneo é um evento incomum, cujo quadro clínico inclui dor pleurítica retroesternal, enfisema subcutâneo, dispneia e disfonia. O mecanismo fisiopatológico implicado é o surgimento de uma diferença de pressão entre os alvéolos e estruturas adjacentes, ocasionando ruptura alveolar com posterior dissecção da bainha peribroncovascular e infiltração do mediastino e do tecido subcutâneo pelo ar. Desencadeantes conhecidos incluem exacerbação aguda de asma e situações que exigem a realização de manobra de Valsava. Descrevemos e documentamos por imagens tomográficas a ocorrência de pneumomediastino após a realização de prova de função pulmonar em um paciente com pneumopatia intersticial induzida por bleomicina. Apesar de incomum, a associação entre provas de função pulmonar e síndromes de vazamento de ar tem sido relatada cada vez mais na literatura, e doenças pulmonares, como as pneumopatias intersticiais, contemplam alterações estruturais que facilitam a ocorrência da complicação. .

Neumoparotiditis o neumoparótida en el niño: Un diagnóstico diferencial a considerar / Pneumoparotitis or pneumoparotid: A differential diagnosis to consider

Childhood parotid swelling has a number of differential diagnosis mostly of inflammatory origin. Pneumoparotitis is an uncommon cause of parotid inflammation. It is caused by an excessive increase of intraoral pressure and secondary passage of air into the Stensen or Stenon duct and its glandular branches. Diagnostic clues can usually be obtained by a directed anamnesis. Ultrasonography (US) and computed tomography are essential diagnostic tools for this condition that has a benign course with spontaneous resolution in most cases. We present four cases of pneumoparotitis diagnosed by US in children 5 to 13 years of age. One of the cases occurred after the child chewed gum and made bubbles for a prolonged timeperiod and the other three after inflating baloons, making bubbles inside a pool and after playing the flute. All cases resolved spontaneously after two days. We suggest to consider pneumoparotitis in the differential diagnosis of parotid swellig in children.

Enfisema orbitário compressivo após asseio nasal: relato de caso / Sight-threatening orbital emphysema after nose blowing: case report

O enfisema orbitário é caracterizado pela presença anormal de ar na órbita. Sua ocorrência espontânea não é frequente e a maioria dos casos está associada à fratura de órbita. Relatamos o caso de uma paciente do sexo feminino de 40 anos com quadro de enfisema orbitário unilateral, secundário a asseio vigoroso do nariz. A paciente evoluiu com redução aguda da acuidade visual em decorrência de elevação da pressão intraocular, sendo indicado tratamento de urgência. Foi realizada punção orbitária com agulha 24-gauge próximo à região da incisura supraorbital, com melhora imediata do quadro clínico e recuperação da acuidade visual.

Orbital emphysema is the abnormal presence of air in the orbit. Occurrence in the absence of orbital fracture is rare. We report a case of a 40-year-old female presenting unilateral orbital emphysema after vigorous nose blowing. She developed sudden visual loss as a result of elevated intraocular pressure and urgent treatment was required. She underwent an orbital decompression, performed using a 24-gauge needle puncture adjacent to the supraorbital notch. After treatment, she reported considerable decrease of symptoms.

Transconjunctival orbital emphysema caused by compressed air injury: a case report.

Orbital emphysema following conjunctival tear in the absence of orbital wall fracture, caused by air under pressure is rare. Usually orbital emphysema is seen in facial trauma associated with damage to the adjacent paranasal sinuses or facial bones. To the best of our knowledge, there have been only eight reports of orbital emphysema following use of compressed air during industrial work. The air under pressure is pushed through the subconjunctival space into the subcutaneous and retrobulbar spaces. We present here a rare cause of orbital emphysema in a young man working with compressed air gun. Although the emphysema was severe, there were no orbital bone fracture and the visual recovery of the patient was complete without attendant complications.

Post-Traumatic Pneumocele of the Frontal Sinus

A pneumocele is an abnormal dilatation of a paranasal sinus, most commonly affecting the frontal sinus. Although the etiology of pneumocele is not entirely known, several causative factors have been suggested including trauma, surgery, tumor and infection. We report here a case of post-traumatic pneumocele of the frontal sinus following a head trauma.

Delayed traumatic orbital emphysema

Delayed traumatic orbital emphysema is a rare occurrence. A case of delayed orbital emphysema following trauma is presented in a 27-year-old male. Conservative management resulted in the resolution of the orbital emphysema. A review of the medical literature revealed that only a few isolated cases of orbital emphysema with a similar course have been previously reported

Un caso de enfisema intramuscular tras cirugía toracoscópica valorado con radiología digital / Intramuscular emphysema after thoracoscopy: digital-Rx features

El enfisema intramuscular es una entidad poco frecuente, generalmente asociada a gangrena gaseosa, siendo muy rara su aparición como extensión de un neumomediastino. En el caso presentado por nosotros el enfisema intramuscular es secundario a neumotórax espontáneo asociado inicialmente a neumomediastino y enfisema subcutáneo, visualizado tras bullectomía toracoscópica. La difusión del aire desde un neumotórax al mediastino sólo se produce en el 1-2 por ciento de los casos. La radiología digital nos permite, entre otras posibilidades, ajustar la escala de grises, aplicar filtros de imagen dependiendo de la región anatómica a estudiar o realzar los bordes de la imagen antes de su impresión en placa

Bilateral spontaneous pneumothorax, pneumomediastinum and cervical emphysema complicating cryptogenic fibrosing alveolitis

Cryptogenic Fibrosing Alveolitis is a progressive infiltrative disease of lung parenchyma, and carries high morbidity and mortality. The prevalence of the disease is much higher than what is believed. We wish to present a case who had a short but rapidly deteriorating disease. During the course of illness he developed myocardial infarction, left ventricular failure and rare complication of spontaneous bilateral pneumothorax, pneumomediastinum and cervical emphysema

Pielonefritis enfisematosa: 3 casos / Enphysematous pyelonephritis: 3 cases

We report 3 patients who developed enphysemathous pyelonephritis. All were diabetic females over 50 years of age with unilateral necrotizing pyelonephritis. Intra and perirenal gas was demosntrated and all patients had infection by E. coli X ray and ultrasound studies allowed the diagnosis. Antibiotic therapy was unsuccessful and all patients had to be operated on
