Review
Diphylobothriasis is a well documented disease of humans. On a world scale new infections are reported regularly, especially from Russia and parts of Japan. Globally, new species have been discovered and the etiology of the disease may be changing. Human infections appear to be in decline but it is not clear if the sources of infection are also in decline or if public health awareness has improved. In North America there has been a decline in human cases while in South America an increase in reports from fish, especially salmonids suggests high levels in these fish species. The history of human infections of Diphyllobothrium latum is primarily associated with the consumption of the northern circumpolar distributed pike and percids and is often considered a parasite of humans only. Indeed some researchers believe that D. latum was introduced to North America by northern European immigrants. The more benign human infections of D. dendriticum appears to be primarily associated with salmonids and coregonid fishes and fish eating birds. Although the early cases of diphyllobothriasis in the 1930s in North America came from fish originating in Lake Winnipeg, Manitoba, there was general belief that it was declining in fish populations and therefore of little significance to humans in the area. However, high levels of a plerocercoid in the flesh of walleyes and pike led to rejection of commercially harvested walleye and pike in Manitoba and northern Ontario, Canada, and a financial loss to Aboriginal fishers. D. latum is widely distributed in fishes of Manitoba and is infective to humans where it is not pathogenic and has a life span up to 4.5 years. The distribution and potential infection routes has not changed in a century and is still well established in natural hosts in the boreal regions of North America. Evidence is building for an old pre-European presence in North America, involving the Beringian land bridge and later involvement of susceptible hosts (northern European immigrants).

Review
Diphyllobothriasis, a parasitosis caused by the flatworm Diphyllobothrium latum, is contracted by consuming raw or undercooked freshwater fish. The aim of this study was to evaluate the situation of this parasitosis during the past 20 years in Europe through the analysis of databases and search engines (Medline, Cabi Helminthological abstracts,Yahoo, Google), and through a questionnaire sent to a network of European parasitologists and to microbiological laboratories located on the shores of the large Alpine lakes. This study has shown that several dozen cases have been reported each year in Finland and Sweden, that there have been numerous cases in the French or Italian speaking areas of subalpine lakes, and that sporadic cases only have been observed in Austria, Spain, Greece, Romania, Poland and Norway. Over 30 cases have been identified on the Swiss shores of Lake Maggiore since 1990, and 70 cases on the Swiss and French shores of Lake Leman between 1993 and 2002. Eight to 12% of perch fillets from Lake Leman and 7.8 % of perch from Lake Maggiore were infested with larvae. Contamination sources include marinated fish fillets in northern Europe, 'carpaccio di persico' in northern Italy, and perch and charr consumed raw or undercooked around Lake Leman. Factors allowing the continuation of the parasitic cycle include the continued dumping of wastewater into lakes, yachtsmen who also fish, and a possible animal reservoir.

BACKGROUND
Diphyllobothriasis is estimated to afflict 10-20 million people worldwide; however, this is the first case reported in a United States military aviator. Among the largest parasites of humans, the "fish tapeworm" grows from 2-15 m in length, can live >20 yr in the intestines, and is contracted through consumption of uncooked, unfrozen freshwater or anadromous fish species.
CASE REPORT
A 32-yr-old male F-22 pilot presented with mild stomach cramping, bloating, nausea, and intermittent loose stools. Symptoms were relieved with bismuth subsalicylate until several days later when the patient, during otherwise normal bowel movements, extracted multiple broken segments of tapeworm. Although physically asymptomatic, he was psychologically disturbed. Based on the large number of ova with characteristic shape, size, color, and operculum, coupled with the flattened body, yellowish coloration, and rectangular proglottids with centrally located "rosette" uteri, he was diagnosed with diphyllobothriasis (likely D. latum or D. nihonkaiense). Successful treatment with a single oral dose of praziquantel (>10 mg ยท kg-1) was confirmed by negative stool examination over 60 d posttreatment. He likely contracted the parasite from ingesting salmon sushi or sashimi while previously stationed in Japan.
DISCUSSION
Despite only mild physical symptoms, the pilot's psychological distress and distraction from knowing about the meters-long tapeworm was significant. Prompt treatment was paramount to resumption of military operations. Aviators should be educated and encouraged to eat only well-cooked or previously frozen fish, especially when indulging in cultural cuisine.Kasteler SD. Diphyllobothriasis in a U.S. military aviator.
