We collected fish from the Chicamacomico River, Maryland, and observed solitary ulcerative lesions on the majority of menhaden sampled. One striped bass (Morone saxatilis) had an area of reddening around the base of the dorsal fin. Bluegill (Lepomis machrochirus), channel catfish (Ictalurus punctatus), yellow perch (Perca flavescens), and carp (Cyprinus carpio) were externally nonremarkable. Histologically ulcerative menhaden lesions demonstrated marked chronic inflammatory infiltrate in large areas of exposed necrotic muscle. The ulcers contained granulomata with fungal hyphae in the necrotic tissue. Gram negative rod-shaped bacteria were also observed in the lesions, a common finding in ulcers of aquatic organisms. Our data suggest that typical ulcerative lesions observed on fish from areas of Pfiesteria-like dinoflagellate blooms are reflective of dermatosis, which may be related to a variety of individual or combined environmental stressors. Exposure to dinoflagellate toxin)s) potentially represents one such stressor. The role of Pfiesteria-like dinoflagellate toxin in fish primary lesion development is currently under investigation.","PeriodicalId":77251,"journal":{"name":"Maryland medical journal (Baltimore, Md. : 1985)","volume":"47 3","pages":"106-12"},"PeriodicalIF":0.0,"publicationDate":"1998-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20521325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After a group of researchers established a potential link between exposure to Pfiesteria and an illness causing memory problems, state health authorities closed a portion of the Pocomoke River. To determine the extent of illness, the range of symptoms, potential risk factors for disease, and to provide information to concerned citizens, a toll-free hotline was created. All symptomatic persons who called the toll-free number were administered a standardized questionnaire. Persons who had been exposed to Pfiesteria or Pfiesteria-laden waters were more likely to have respiratory, neurologic, dermatologic, and gastrointestinal problems than those persons without exposure. Among the persons calling the hotline, many had extensive neuropsychologic testing. Of the neuropsychologic test battery, low scores on the Rey Auditory Verbal Learning Test (RAVLT), a standardized measure of learning and memory, best characterized illness related to Pfiesteria exposure. Patients with low RAVLT scores were more likely to have neurologic symptoms and skin lesions than control subjects. Low RAVLT scores were associated with fishing (OR, 9.00, 95% CI, 106, 409.87), catching fish with lesions (OR, 6.17, 95% CI 1.27, 32.10), and handling fish with lesions (OR, 5.34, 95% CI, 1.05, 29.92), but not with consumption of seafood. While preliminary, these results do suggest that some risk factors for Pfiesteria-related illness may be easy to modify and used to prevent unnecessary human exposure.","PeriodicalId":77251,"journal":{"name":"Maryland medical journal (Baltimore, Md. : 1985)","volume":"47 3","pages":"137-43"},"PeriodicalIF":0.0,"publicationDate":"1998-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20521214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants in the exposed group were seven symptomatic recreational and commercial fishermen who had direct exposure to the Pocomoke River or other estuarial waters on Maryland's Eastern Shore before, during, and/or after periods of documented fish kills and Pfiesteria activity. The control group included eight commercial fishermen who worked on the ocean side of the Eastern Shore and had no reported exposure to estuaries with documented Pfiesteria activity. Both exposed symptomatic and nonexposed watermen completed the Profile of Mood States to assess depression, anxiety, and other relevant mood states as part of their participation in the larger investigation of the human health effects of Pfiesteria piscicida. Preliminary results suggest that both exposed symptomatic and nonexposed watermen are psychologically healthy and exhibit what psychologists refer to as the classic Iceberg Mood Profile. The Iceberg Profile is characterized by endorsement of symptoms suggestive of high energy, enthusiasm and positive mood (e.g., lively, active, energetic, cheerful, vigorous, etc.) and relative minimization of symptoms suggestive of negative or depressed mood (e.g., tense, anxious, restless, grouchy, forgetful). Therefore, the Pfiesteria-related symptom complex documented in the exposed watermen cannot be explained by functional or psychiatric factors and is probably due to exposure.","PeriodicalId":77251,"journal":{"name":"Maryland medical journal (Baltimore, Md. : 1985)","volume":"47 3","pages":"130-2"},"PeriodicalIF":0.0,"publicationDate":"1998-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20521212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
