Pyogranulomatous pleuropneumonia caused by Nocardia asiatica in a dog coinfected with canine morbillivirus (canine distemper virus).

Nocardia asiatica causing pyogranulomatous pleuropneumonia is reported for the first time in a dog coinfected with canine morbillivirus (CM), diagnosed based on epidemiological, clinical, haematological, images, microbiological, histopathological, polymerase chain reaction and hsp65 gene sequencing findings. The immunosuppression of CM probably favoured the opportunistic behaviour of N. asiatica. Despite the therapeutic measures, the animal died, mainly due to respiratory distress. The association of methods to improve early diagnosis, therapy procedures and prognosis of canine nocardiosis is discussed, as well as the close relationship between pets and their owners, which may favour the transmission of pathogens such as Nocardia from pets-to-humans, which poses an emerging public health issue.

[Chest ultrasonography in pediatric critical care practice]. / Apport de l'échographie pleuropulmonaire en pédiatrie.

An increasingly amount of evidence suggests that lung ultrasonography constitutes a relevant complementary diagnostic tool for adults patient in acute respiratory failure. A comprehensive and standardized ultrasonographic semiology has been described, relying on accurate and reproducible data directly obtained at patient's bedside. Therefore, pleural effusion, pneumothorax, pulmonary consolidation and interstitial lung disease can be diagnosed in a critical care environment with a similar level of performance than when reference diagnosis methods such as thoracic CT-scan are employed. Furthermore, lung ultrasonography seems to be able to contribute to an early therapeutic decision based on such online physiopathological data. Pioneers works in this field have suggested an attractive similarity between the ultrasonographic patterns described in adults and children. Nevertheless, the clinical usefulness of lung ultrasonographic approach in the pediatric critical care medicine still needs to be confirmed by specifically designed studies.

[Persistent pleuropneumopathy in a young woman]. / Une infection pleuropulmonaire non résolutive chez une femme jeune.

Bronchopulmonary sequestration is a rare malformation characterized by lung tissue fed by one or several aberrant systemic arteries. The authors present the case of a 35-year-old woman in whom extralobar sequestration was fortuitously detected at the time of persistent pleuropneumopathy. Computed tomography was used in the diagnosis of pulmonary sequestration. The most common and recommended treatment is the surgical removal of the pulmonary sequestration.

Diagnosis of radio-occult pulmonary conditions by real-time chest ultrasonography in patients with pleuritic pain.

The evaluation of pleuritic pain in the emergency department (ED) presents a considerable challenge for the attending physician. Chest radiography (CXR) is a basic test, but its sensitivity is low, and often more sophisticated imaging techniques are needed. Our aim is to assess the diagnostic value of bedside B-mode lung ultrasound (LUS) in the visualization of radio-occult pulmonary lesions. Forty-nine patients complaining of pleuritic pain with negative CXR were prospectively studied by LUS. Detection of at least one of the following sonographic signs in the painful thoracic area was considered diagnostic: (i) the absence of pleural sliding; (ii) the focal alveolar-interstitial syndrome (AIS), defined by multiple artifacts B-line; (iii) the peripheral alveolar consolidation (PAC), defined by hypoechoic subpleural images; and (iv) the pleural disruption with thickening and irregularity of the line, with or without localized effusion. The final diagnoses were confirmed by spiral CT scanning (n = 12) and follow-up (n = 37). Final diagnoses were chest wall pain (n = 30), pleuropneumonia (n = 14), pulmonary embolism (n = 4), lung metastasis (n = 1). In 18 patients of the group with pulmonary conditions, LUS showed signs of pleurisy. They were PAC (n = 12), AIS (n = 17), pleural disruption (n = 17). If any sign is considered, the sensitivity of LUS in the diagnosis of radio-occult lesions was 94.7%, specificity was 96.7%, positive and negative predictive values were 94.7% and 96.7%, respectively, and accuracy was 95.9%. In patients with pleuritic pain of unknown cause, real-time LUS enables the diagnosis of radio-occult lung and pleural lesions.

Contrast-enhanced sonography for differential diagnosis of pleurisy and focal pleural lesions of unknown cause.

BACKGROUND: Ultrasound enables the visualization of pleural-based lesions with a poor correlation to specific pathology. At this time, there are no data about the diagnostic value of contrast-enhanced sonography (CES) in pleural lesions. METHODS: From August 2004 to January 2005, 25 consecutive patients with clinical symptoms of pleurisy and focal pleural lesions of unknown origin seen on B-mode ultrasonography were prospectively studied by CES. The lesions were diagnosed as pleuropneumonia (n = 12), pulmonary embolism/infarction (n = 7), malignant lymphoma (n = 2), pleural metastasis (n = 2), granuloma (n = 1), and unknown cause (n = 1). The diagnosis of the lesions was confirmed by contrast-enhanced CT scanning (n = 20), scintigraphy (n = 3), and follow-up (n = 2). Time to the enhancement of the contrast agent was determined. The CES patterns were evaluated during the arterial phase (ie, 2 to 30 s) and the parenchymal phase (ie, 1 to 5 min). The extent of the enhancement of pleural lesions was classified using normal liver tissue as an in vivo reference (absent, hypoechoic, isoechoic, hyperrechoic, or mixed echogenicity). RESULTS: In 20 patients, an enhancement of the pleural lesion was seen. All 12 patients with pleuropneumonia had a short time to enhancement (between 1 and 6 s), and a marked enhancement (isoechoic/hyperechoic) during the arterial and parenchymal phase. In the remaining 13 patients with other diagnoses than pleuropneumonia, 5 patients had no enhancement and 8 patients had a delayed time to enhancement (> 6 s). The extent of the enhancement was reduced (hypoechoic/anechoic) in 12 of 13 patients during the arterial and parenchymal phases. CONCLUSION: In patients with pleurisy and pleural lesions of unknown cause that were found sonographically, CES enables the diagnosis or exclusion of pleuropneumonia.

[Severe regional and distant complication of tonsillitis. Case report]. / Ciezkie powiklania regionalne i odlegle zapalenia migdalków podniebiennych. Opis przypadku.

The authors describe a 66-year-old male patient treated for angina that was complicated by para- and retropharyngeal phlegmon, mediastinitis and pleuropneumonia. The role of imaging procedures and bacteriological examination was found especially important in establishing the diagnosis and introducing the right treatment. Efficacy of external (transcutaneus) approach to the para- and retropharyngeal space and phlegmon drainage of these spaces preceded with tracheotomy and tonsillectomy was underlined. Surgical treatment was supplemented with multi-component antibiotic therapy and gammaglobulin administration.

[Acute abdomen: consider also the thorax]. / Acute buik: denk ook aan de thorax.

Three patients, 2 men aged 22 and 62 years en 1 woman aged 49, presented with symptoms of an acute abdomen. While infiltrative signs were described on radiodiagnostic images two patients underwent laparotomies. In all three subsequently the diagnosis of pneumonia was established and the patients made full recovery after antibiotic therapy. When a patient presents with symptoms of an acute abdomen, the possibility of an existing pneumonia should always be borne in mind. It is therefore recommended to make a chest radiograph with frontal and lateral view. In the presence of infiltrative signs the existence of pneumonia as the cause of abdominal symptoms should be considered in order to avoid unnecessary laparotomy.

CT diagnosis of delayed presentation of congenital diaphragmatic hernia simulating massive pleuropneumonia.

A case of an 11-month-old infant with a delayed presentation of congenital diaphragmatic hernia is reported. Incarceration of the herniated colon caused a misleading appearance on the chest X-ray which was interpreted as massive pleuropneumonia. Computed tomography, performed because of continuing deterioration in the clinical condition, showed fluid-filled bowel loops in the chest and dilated bowel loops with air-fluid levels in the abdomen, suggesting the correct diagnosis.

[Pleuropneumopathy caused by bromocriptine in a patient with Parkinson disease. Review of the literature apropos of a new case]. / Pleuropneumopathie à la bromocriptine chez un parkinsonien. Revue de la littérature à propos d'une nouvelle observation.

Bromocriptine, a derivate of ergot of rye, is employed in high doses for the treatment of Parkinson's disease, and may induct pleuropulmonary affections. We report the case of a 75-years-old patient, on bromocriptin for 5 years, who presented a progressive dyspnea, due to a pleural thickening, and moderate interstitial infiltrate, associated with an inflammatory syndrome. The outcome was favorable with 3 months of bromocriptin cessation. These complications are rarely described, probably underestimated, and justify a respiratory follow-up for these patients, who are difficult to stabilize in their neurologic treatment.

Ultrasonographic findings in cattle with pleuropneumonia.

The clinical, ultrasonographic and radiographic findings in three cows and one bull with pleuropneumonia are described. All the animals had fever, indigestion, tachypnoea and abnormal lung sounds. Percussion of the thoracic wall elicited signs of pain and tests for foreign bodies were positive. Ultrasonographic examination revealed an accumulation of anechogenic to hypoechogenic fluid in the pleural space in the ventral thorax of all the animals. In one animal, echogenic bands of fibrin were observed between the thoracic wall and pulmonary surface. In another, parts of the right lung were not inflated because of severe bronchopneumonia. Radiographic examination revealed a pleural effusion, apparent as a horizontal fluid line, in three animals. In addition, the increased radiopacity in parts of the dorsal lung fields and increased bronchial and peribronchial markings suggested bronchopneumonia. In three animals, the radiographs revealed linear foreign bodies in the reticulum, suggesting that the pleuropneumonia was caused by the penetration of the foreign body into the thoracic cavity. A diagnosis of pleuropneumonia was made in all the animals on the basis of the clinical, ultrasonographic and radiographic findings and the analysis of the pleural fluid. The diagnosis was confirmed at slaughter in three of them; the fourth animal was treated and was clinically healthy when it was discharged.

Suppurative pleuropneumonia and a pulmonary abscess in a ram: ultrasonographic and radiographic findings.

This report describes a two-year-old White Alpine ram with suppurative pleuropneumonia and a lung abscess. Prior to admission, the ram had been unsuccessfully treated with antibiotics and levamisole. Clinical examination revealed that the general behaviour and condition of the ram were severely disturbed. The rectal temperature and respiratory rate were increased. Auscultation of the lungs revealed increased vesicular sounds. Based on clinical findings, a tentative diagnosis of bronchopneumonia was made. To confirm the diagnosis, blood was taken for serological testing for Maedi-Visna, and endoscopic examination of the respiratory tract and ultrasonographic and radiographic examination of the thorax were performed. Cytologic and bacteriologic examination of tracheal secretions revealed large numbers of neutrophils and Actinomyces pyogenes organisms. A pocket of gas, surrounded by a capsule of soft tissue density, overlying the base of the heart, and a horizontal fluid line were observed on radiographs. Ultrasonographic examination revealed an effusion between the pleura and the lung on the left side of the thorax; an encapsulated abscess was seen on the right side of the thorax. Centesis and aspiration of this accumulation of fluid yielded foul-smelling pus. Post mortem examination confirmed the clinical, radiographic and ultrasonographic findings. The ram had severe chronic suppurative pleuropneumonia with abscess formation between the pleura and lung on the right side.
