1/5. North American paragonimiasis. A case report.BACKGROUND: paragonimiasis is a parasitic infection with a predilection for pulmonary involvement. Paragonimus species occur throughout the world and exist in nature in a snail-crustacean-mammalian life cycle. Human disease is most frequently encountered in cultures that ingest raw or undercooked crustaceans. North American paragonimiasis, caused by an endemic Paragonimus species, Paragonimus kellicotti, predominantly causes disease in carnivorous and omnivorous animals but may cause human disease if the intermediate host, the crayfish, is ingested raw or undercooked. CASE: A previously healthy, 21-year-old male was infected with P kellicotti and developed parasitic hemoptysis. The disease was contracted through the ingestion of local, undercooked crayfish. diagnosis was established through the morphologic examination of eggs in the cytologic preparation of bronchioalveolar lavage fluid. The patient was successfully treated with praziquantel and recovered without incident. CONCLUSION: paragonimiasis is a cause of parasitic hemoptysis worldwide. paragonimiasis is infrequently encountered in north america and is usually not considered in the differential diagnosis of hemoptysis unless specific risk factors are known. The cytologist or cytopathologist, therefore, may be the first to encounter the diagnostic eggs and should be familiar with this disease.- - - - - - - - - - ranking = 1keywords = paragonimiasis (Clic here for more details about this article) |
2/5. Just another hemoptysis or a fluke?Hemopytsis is commonly encountered in the daily practice of the pulmonary physician. Younger patients with normal chest x-rays frequently have acute or chronic bronchial disease accounting for their complaint. Occasionally parasitic disease is described as an unusual cause for a patient presenting with hemoptysis. Although pulmonary paragonimiasis is unusual in this country, because of the rapid growth in travel as well as immigration, physicians will need to be aware of this disorder.- - - - - - - - - - ranking = 0.2keywords = paragonimiasis (Clic here for more details about this article) |
3/5. Cavitary mass lesion and recurrent pneumothoraces due to Paragonimus kellicotti infection: North American paragonimiasis.North American paragonimiasis is well described in omnivorous and carnivorous animals on this continent. humans are rarely infected, largely because of dietary customs, but are at risk for infection if raw or undercooked crayfish are consumed. We describe a patient with a pleuropulmonary infection due to Paragonimus kellicotti that presented as recurrent pneumothoraces and a cavitary lesion. This is the first case of North American paragonimiasis in which the diagnosis was based on the morphology of the eggs present in histologic sections.- - - - - - - - - - ranking = 1.2keywords = paragonimiasis (Clic here for more details about this article) |
4/5. Pulmonary paragonimiasis in childhood--a cause of recurrent haemoptysis and pneumonia.A 2-year-old Manipuri girl had haemoptysis and a chest roentgenogram disclosed diffuse-infiltrates in the right lung. Microscopic examination of sputum and morning gastric aspirate showed numerous golden-brown, operculated ova, and microscopic examination of stool specimens confirmed these ova to be those of the lung fluke, paragonimus westermani. She responded favourably to bithionol therapy and was asymptomatic and growing normally during follow up for one and half years.- - - - - - - - - - ranking = 0.8keywords = paragonimiasis (Clic here for more details about this article) |
5/5. Pulmonary paragonimiasis in childhood. A cause of persistent pneumonia and hemoptysis.A 4-year-old Filipino girl, a recent immigrant to hawaii, had hemoptysis, and a chest roentgenogram disclosed diffuse infiltrates of the right lung. Microscopic examination of a morning gastric aspirate showed numerous golden-brown, operculated ova, and microscopic examination of sputum and stool specimens confirmed these ova to be those of the lung fluke, paragonimus westermani. She responded favorably to bithionol therapy and was asymptomatic and growing normally 2 1/2 years after therapy.- - - - - - - - - - ranking = 0.8keywords = paragonimiasis (Clic here for more details about this article) |
