1/168. Extraction of a rubber bullet from a bronchus after 1 year: complete resolution of chronic pulmonary damage.inhalation of a foreign body (FB) into the bronchial tree rarely occurs asymptomatically and, if leading to recurrent pneumonia, can be very difficult to diagnose. The present report deals with the case of a 10-year-old boy who had three episodes of pneumonia in the left lower lobe caused by the asymptomatic inhalation of a FB 12 months before. Standard thoracic CT, done during the third episode, revealed a slight reduction in the volume of the left lung with air bronchograms, multiple areas of bronchiectasis, and parenchymal consolidation of a segment of the lower lobe. Flexible fiberoptic bronchoscopy revealed a FB at the distal end of the left lower lobar bronchus, surrounded by granulation tissue and fully obstructing the anterior basal segmental bronchus. High-resolution CT (HRCT) images showed an inverted C-shaped image obstructing a bronchus. Removal of the FB was successful only with rigid bronchoscopy under total anesthesia. The FB was an air-pistol rubber bullet that the boy remembered playing with 12 months before. Two months after removal of the FB (ie, 14 months from its asymptomatic inhalation) and treatment with oral steroids, antibiotics, and respiratory physiotherapy, the patient recovered completely, and HRCT showed complete normalization of the lung. We conclude that, when the radiographic density of the FB is greater than the surrounding pulmonary parenchyma, HRCT can reveal the FB, and diagnostic flexible fiberoptic bronchoscopy can be avoided.- - - - - - - - - - ranking = 1keywords = tract (Clic here for more details about this article) |
2/168. Ectopic thymic tissue: a cause of emphysema in infants.Ectopic thymic tissue can present a diagnostic dilemma when it is located in the posterior mediastinum. The diagnosis can be made by awareness of it and by use of computed tomography (CT) and magnetic resonance imaging (MRI). Rarely, ectopic thymus are reported to cause airway obstruction. In infants ectopic thymic tissue should also be considered in the differential diagnosis of secondary pneumonias and emphysema especially located in the upper lung zones.- - - - - - - - - - ranking = 0.024851890632201keywords = upper (Clic here for more details about this article) |
3/168. How useful is the chlamydia micro-immunofluorescence (MIF) test for the gynaecologist?Three patients with a chlamydial respiratory tract infection showed significant titre rises for the three chlamydial micro-immunofluorescence tests, performed with chlamydia pneumoniae, C. psittaci and C. trachomatis. Such cross-reactions procure an inaccurate discrimination between the various chlamydia species which remains speculative anyhow when only a positive serological profile against one chlamydial subspecies is performed. We consider that using the serologic assay as proof for past sexually transmitted C. trachomatis infection falls outside the limits of prudent interpretation of laboratory tests.- - - - - - - - - - ranking = 596.59269236871keywords = respiratory tract infection, respiratory tract, tract infection, tract (Clic here for more details about this article) |
4/168. Acute mercury vapour poisoning in a shipyard worker--a case report.Acute mercury vapour poisoning is a serious, potentially fatal but fortunately rarely encountered problem. It is most commonly due to industrial accidents. The vapour is a direct respiratory tract irritant as well as a cell poison, exerting its greatest effects in the lungs, nervous system, kidneys and liver. We present a case of mercury vapour poisoning in a shipyard workers presenting as an acute chemical pneumonitis, which resolved with aggressive supportive therapy. Further investigations later revealed transient mild neuropsychiatric symptoms, and residual peripheral neuropathy. No chelation therapy was instituted. The detailed investigative work that led to the discovery of the source of mercury is also presented. This case alerts us to the potential hazard to shipyard workers who may work in ships previously carrying oil contaminated with mercury. There have been no previous reports of mercury poisoning in shipyard workers. A high index of suspicion leading to early diagnosis and institution of appropriate supportive measures in suspected cases can be life-saving.- - - - - - - - - - ranking = 95.951798740995keywords = respiratory tract, tract (Clic here for more details about this article) |
5/168. A 92-year-old man with systemic lupus erythematosus who developed acute lupus pneumonitis.We describe a 92-year-old male patient with systemic lupus erythematosus (SLE) who had sudden onset of thrombocytopenia and developed acute lupus pneumonitis (ALP). Although steroid pulse therapy was effective for ALP, he developed complicated bacterial pulmonary disease. This patient is the oldest ever reported to have contracted SLE.- - - - - - - - - - ranking = 0.25keywords = tract (Clic here for more details about this article) |

7/168. Cavitating pulmonary infiltrate in an adolescent with pyoderma gangrenosum: a rarely recognized extracutaneous manifestation of a neutrophilic dermatosis.Neutrophilic dermatoses such as pyoderma gangrenosum are characterized by sterile, neutrophilic cutaneous infiltrates. Extracutaneous neutrophilic infiltrates can occur, primarily in the joints, lungs, heart, central nervous system, gastrointestinal tract, and eyes. Pulmonary disease is the most frequently reported extracutaneous manifestation of pyoderma gangrenosum and is characterized by patchy infiltrates or interstitial pneumonitis. We describe an adolescent with typical pyoderma gangrenosum who presented with cavitary pneumonia and responded completely to oral corticosteroids. In patients with inflammatory ulcers, extracutaneous neutrophilic disease should be considered, once an infectious process has been excluded.- - - - - - - - - - ranking = 0.25keywords = tract (Clic here for more details about this article) |
8/168. Intrapulmonary sequestration with arterial supply from the left internal thoracic artery: a case report.Pulmonary sequestration is uncommon in the upper lobe. Its arterial supply from the internal thoracic artery is very rare. Reported here is a case of a 20-year-old male whose presenting symptom was recurrent pneumonia. Helical computed tomography (CT) and three-dimensional reconstruction images showed that aberrant arteries arising from the left internal thoracic artery were supplying the area of sequestration and draining into the pulmonary vein. Selective intra-arterial digital substraction angiogram also showed left internal thoracic artery supplying the area of the sequestration. Helical three-dimensional CT is noninvasive and provides as accurate three-dimensional information of the aberrant vascular supply in intrapulmonary sequestration as the angiography.- - - - - - - - - - ranking = 0.2748518906322keywords = tract, upper (Clic here for more details about this article) |
9/168. Failure to clear casts and secretions following inhalation injury can be dangerous: report of a case.A 27-year-old man suffered smoke inhalation during a fire. Three days later, he complained of respiratory difficulty and was admitted to our hospital. bronchoscopy revealed a very large buildup of sputum mixed with soot extending from the left main bronchus to the bifurcation of the upper and lower lobe bronchi and causing both pulmonary atelectasis and pneumonia. The debris was successfully removed the next day with basket forceps via bronchoscopy. The patient's airway pressure dropped significantly, enabling extubation almost immediately. Because of the possibility for respiratory failure caused by viscous secretion, it is important to perform initial bronchoscopy in cases of suspected inhalation injury.- - - - - - - - - - ranking = 0.024851890632201keywords = upper (Clic here for more details about this article) |
10/168. Meningococcal group Y pneumonia in an adolescent female.neisseria meningitidis group Y has been considered to be an uncommon pathogen. Meningococcal group Y disease has recently been reported with increased frequency in military training camps coincident with the routine use of meningococcal group C vaccine. pneumonia produced by the group Y organism may mimic disease caused by common respiratory tract pathogens, and isolation by routine methods may be difficult. A 16-year-old asthmatic female developed lobar pneumonia secondary to N meningitidis group Y while on alternate day steroids. We speculate that neither steroid therapy nor an isolated serum iga deficiency in the presence of secretory IgA discovered after her recovery predisposed her to sinopulmonary disease. The true incidence of group Y disease is unknown. awareness of its potential pathogenicity may have clinical significance with the availability of a group Y vaccine.- - - - - - - - - - ranking = 95.951798740995keywords = respiratory tract, tract (Clic here for more details about this article) |
