Pleural complications of pulmonary hydatid disease

RESPIROLOGY, Issue 1 2004
Mustafa Kursat Ozvaran
Objective: The aim of this study was to determine the incidence and diagnostic features of pleural manifestations of pulmonary hydatid disease. Methodology: Patients with pleural pathology in association with surgery for pulmonary hydatid disease over an 8-year period were evaluated. Results: Twenty-nine (6%) of 474 patients with histologically confirmed pulmonary hydatid disease had pleural abnormalities. The diagnosis was determined preoperatively in 22 patients and was based on radiographic, clinical, and/or serology findings. Bronchoscopic specimens were diagnostic in two of seven patients who had bronchoscopy. Five patients were not diagnosed until surgery. Radiographic abnormalities consisted of pleural thickening and/or free fluid without intrapleural rupture of the cysts in 21 patients. Eight patients had a hydropneumothorax. Sixteen patients had an exudative, uncomplicated effusion. The remaining patients had empyemas. All patients had resection of the pulmonary cysts, and 20 also underwent a pleurectomy. The mean length of hospital stay was 23 ± 14 days. There was no hospital mortality. Conclusion: Pleural lesions associated with pulmonary hydatid disease are rare and have a variable radiographic appearance. In regions in which echinococcal disease is endemic, a high level of clinical suspicion is necessary for diagnosis and appropriate management of this condition. [source]


Scintigraphic examination of the cartilages of the foot

EQUINE VETERINARY JOURNAL, Issue 3 2007
A. NAGY
Summary Reasons for performing study: Radiographic examination of the cartilages of the foot is well documented; however, there is limited information about their scintigraphic assessment. Objectives: To evaluate the scintigraphic appearance of the cartilages of the foot using subjective and quantitative image analysis and to correlate radiographic and scintigraphic findings. Hypotheses: An ossified cartilage would have similar radiopharmaceutical uptake (RU) to the ipsilateral aspect of the distal phalanx; RU would extend throughout the length of the ossified cartilage; a separate centre of ossification (SCO) would be identified on a scintigraphic image; and fracture or trauma to an ossified cartilage would manifest as increased RU (IRU). Methods: Front feet (n = 223) of horses (n = 186) that had dorsopalmar radiographic views and dorsal scintigraphic images were included in the study. The cartilages of the foot were graded radiographically and scintigraphically. Quantitative evaluation of the scintigraphic images was carried out using region of interest (ROI) analysis. For statistical analysis RU ratios were used. Correlations between a radiographically detected SCO and focal RU and between IRU and radiographic abnormalities were assessed. Results: There was a good correlation and an excellent agreement between radiographic and scintigraphic grades. ROI analysis showed a proximal to distal increase in RU ratios within each cartilage of the foot. A radiographically identified SCO could be detected scintigraphically in 12/17 feet (70.6%). Thirty-eight feet had IRU in the region of a cartilage, 25 of which (65.8%) had corresponding radiographic abnormalities. Fracture of an ossified cartilage was associated with IRU in all horses. Conclusions and potential relevance: Scintigraphy may give information about the potential clinical significance of ossification of the cartilages of the foot and associated lesions, therefore prompting further investigation by use of a uniaxial ipsilateral palmar nerve block and imaging, using either magnetic resonance imaging and/or computed tomography.

Intentional replantation of an immature permanent lower incisor because of a refractory peri-apical lesion: case report and 5-year follow-up

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 3 2004
S. Shintani
Summary., We performed an intentional replantation of an immature lower incisor that had a refractory peri-apical lesion. The incisor was extracted and the peri-apical lesion was removed by curettage. The root canal of the tooth was then rapidly irrigated, and filled with a calcium hydroxide and iodoform paste (Vitapex®), after which the tooth was fixed with an arch wire splint. Five years later, no clinical or radiographic abnormalities were found, and the root apex was obturated by an apical bridge formation. A team of two dentists is essential to prevent a prolonged operation time, thus eliminating any of the causes of ankylosis. Furthermore, calcium hydroxide and iodoform paste, along with an arch wire splint retained with composite resin, led to good healing of the periodontal tissue after the intentional replantation. Our results indicate that intentional replantation is a useful method for an immature tooth with refractory peri-apical problems. [source]


Lung function decrease in relation to pneumoconiosis and exposure to quartz-containing dust in construction workers

Abstract Background Prevalence of exposure related respiratory symptoms and decreases in lung function are unknown among quartz dust exposed construction workers. Methods In a cross-sectional study (n,=,1,335), the occurrence of respiratory symptoms, was recorded and spirometric lung function was measured. Results were associated with exposure data and presence of radiographic abnormalities and compared with a reference population. Results Pneumoconiosis (profusion category 1/1 or greater) was associated with increased risks of FEV1 and FVC values in the lowest 5% group, and with group-based decreases of 270 ml/s and 180 ml, respectively. Average lung function of construction workers was somewhat lower compared to a Dutch reference population. Lung function was not associated with exposure, except for a reduction in FVC of 5 ml per year for those with higher exposure. Conclusions In quartz dust exposed construction workers obstructive and restrictive lung function loss was detected. Am. J. Ind. Med. 43:574,583, 2003. © 2003 Wiley-Liss, Inc. [source]
