After a couple of post-convalescentdays in Cairo, he traveledup the Nile as far as Luxor. He spent three days in Luxor, wandering among its many antiquities and swimming in the Nile, and then returned to Cairo. From Cairo, he flew to Amman, from included foods, drugs, dusts, and pollens. In this instance,however. the circumstancesseemedclearly to implicate a drug-the penicillin injections that Berry had been given in Honk Kong' Allergic symptoms, too, could be satisfactorily controlled, with cortisoneand antihistamines:But Berry must also do his part' He was to rest in bed, drink plenty of water, and report to the clinic daily for treatment and observation until further notice' Berry did as he was told. He reported to the Adventist clinic Amman to Beirut, from Beirut to Ankara, and from Ankara to Athens. He halted there, at a students'hostel, for two nights and a day. On April 28, he left by plane for Zurich and a tour of Western Europe. In the course of the next six or eight weeks,he visited Geneva, Marsetlie, Barcelona, Madrid, Paris, Brussels, Amsterdam, Frankfort. Muntch, and Vienna' An allergic puffi- every day for nine days. At the end of that time, he was discharged to convalesceon his own. The following day, he took a train to Rangoon. Except for a httle swelling around the eyes'his allergic symptoms had largely subsided, but he still was somewhat diarrheic. He spent the next week traveling by plane and train and bus through Burma and East Pakistan to Calcutta. He reached nessaround the eyesplaguedhim off and on, but otherwsiehe felt encouragingly well. On hrs second morning in Vienna, he was awakenedby a twinge of abdominal pain. It came again while he was dressing,and agatn on the way to breakfast. Then it went there feeling tired and apprehensive,He had lost twenty-five pounds in the past two weeks and had had to force himself to eat' He rested for a day in a Salvation Army hostel and then sought out a doctor. The doctor found him nervous and undernourished, and recommended vitamins. Berry took his advice. A few days later, having exhaustedthe sights of Calcutta, he moved on, by away. Nevertheless,it made him uneasy,and that afternoon he had himself directed to the office of a urologist. The urologist questionedhim closely about his Damascus experience,and did a urinalysis.The results,he reported, were entirely normal. Thus reassured,Berry resumedhis travels.Betweenthe end of June and the end of July, he visited Berhn. Copenhagen,Stockholm, Oslo, and London. Early in August, he sailedfrom Southamptonon the train, to New Delhi. From there, he flew to Karachi. It had been his intention to spend severaldays in Karachi, but he stayedonly threw on his clothes, overnight. He awoke in a knot of restlessness, and caught a plane for Damascus.On the way, he becameaware Queen Elizabeth for New York. of a leaden ache low rn his back and flanks. It smoldered there throughout the rest of the flight. Then, as the plane came bumping down at Damascus, it shifted around to his abdomen and sharpened into a twitching pain. Berry rode uncomfortably into the Berry settled down in JerseyCity again, and after a week or two ol looking around he found a.lob as a draftsman with an architectural firm. He lived with his parents and saw his old friends and did as he had always done. It was not, however,as if he had never city with the glum conviction that he was going to be sick again' A French doctor confirmed his fears. Berry had a temperatureof just over a hundred, and there was a trace of blood in his urine' Those findings, together with the location of the pain, suggested heen away. The allergic puffinessaround his eyes persisted,and the itches and swellingselsewhereon his body continued to come lnd go. In addition, early tn Septemberhe began to feel a vague and vagrant nausea.The feeling was particularly pronouncedjust a kidney infection. Either that or renal colic. Whatever the nature of Berry's illness,it kept him in a nursing home in Damascus for a little over a week. He emerged,wobbly but well, on April 14, and had a final consultationwith the doctor' before meals. He told himself that it would soon go away, and w hen i t di dn' t, he tried t o t gnor eit . At t he end of a week,he gave rrp and called the family doctor for an appointment. The doctor rramined him with care, and admitted that he was stumped.

It showeda morbidly significantincreasein white blood cells of a That tendedto suggestthe presence kind known as eosinophiles. of infection.The possibilitieswere too numerousto mention,but a consultationwith a specialistmight help to sort them out' He would make an appointmentfor Berry with an internist of his A few dayslater, Berry emergedfrom anotherthoracquaintance. ough examinationwith another equivocalreport' Except for a notably elevatedeosinophilecount, all testsand soundingsPerformed by the internist had had negativeresults.The internist, however,was not completelydeterred.He had formed,he said,a certainimpression-a hunch. Eosinophilia,he remindedthe family doctor,is characteristicof tnchinosis.Soareallergic-likeswellings around the eyes,and urticarial itches.He wonderedif a mild trichinal infection might not be the causeof the patient'scomplaint. The family doctor passedthis tenuous diagnosison to Berry, adding that he was generallyinclined to concur. There is no specifictreatmentfor trichinosis,but in the great majority of casestime will effecta cure. The curativepowersof time did next to nothing for Berry. Although the swelling around his eyessubsided,and the occasionalhives and itches graduallyceasedto recur, the draggingmealtimenauseaand the ambiguous eosinophilia continued unabated-for weeks, for months, for a year. Then, one Saturdayafternoonin October' 1959,Berry passedin his stool a ten-inchworm. He submitted the specimen,in consternation,to the family doctor. The latter was able to reassurehim. The worm was a speciesof round worm (Ascarislumbricoides),an intestinalparasiteonly slightly less common than a tapeworm. It was also, the doctor went manfully on to say, the probablecauseof what had seemedto point to trichinosis.Nor wasthat all. Ascariasis'unliketrichinosis, was readily responsiveto treatment.The drug of choicewas piperazinecitrate,and a singledosewas usuallysufficient.It was in Berry's case.Within a week, his stomach had steadiedand settled,and he felt almost like himself again' The only trouble .1Swim in the Nile $ 129 rvas his eosinophile count. It had dropped, but it still stood abrrormally high. Around the middle of November, Berry was seized with a new :rffiiction.It hurt him to urinate. He endured this puzzling complaint for several uneasy days, and then went down to see the ,loctor. The doctor heard his symptoms with reliel and an examination, which disclosed an inflammation of the prostate gland, eonfirmed his first impression. Berry had prostatitis. The doctor then turned his attention to treatment. It consistedof a prostatic rnassage,a prescription for sulfisoxazole,and a warmly encouragrng prognosis. He was hopeful that by the end of the week Berry would be greatly improved. It didn't turn out that way' The pain ,:clntinuedas before. A cystoscopic, or direct, examination of the urinary tract was made, and thesefindings,too, were inconclusive' fhe doctor saw no reasonto alter his diagnosis.Or his treatment' [{e was convinced that periodic prostatic massagewould eventu' rullyhave a salutary effect. And so, before long, it apparently did. Berry's occasionalabdominal cramps becameincreasinglyoccasional,and presentlycarly in 1960--they vanishedaltogether'This was followed by an ('rlcouragingchangein his original urinary complaint' For a while, rt seemedto Berry that his troublesmight be almost over. But only lirr a while. The remissions,it soon became clear, were nothing rnore than remissions.In time, the pain always returned' Toward rhe end of I 960, Berry gaveup any real hope of a cure and resigned hrmselfto a life of chronic prostatitis. Berry's life as a chronic invalid lasted almost a year' It tnded, with a jolt, one December evening in 1961, when he noticed a stain of blood in his urine. The next morning, it had rroticeablydeepenedand darkened. Sick with dismay, he telephoned the family doctor. The doctor told him to come to the ,rfficeat once. From there, on the doctor's referral, he went to \ce a urologist. The urologist asked some careful questions, .rnd then led him into his surgery for another cystoscopicexrrnination.

The cause of schistosomiasisis a small but readily visible endoparasitic worm of the genus schistosomT that has an essential environmental predilection for human blood' Its name derives from the Greek schistos,meaning "cleft," and soma' meaning "body," and refers to a deep longitudinal crevice in the body of the male worm in which the female more or less permanently though humbly placedin the evolutionresides.The schistosomes, ary scale,lead highly complicatedlives' They reach maturity on!y after three total metamorphoses in three distinctly different set- .4 Swim in the Nile $ 131 tings. The organism first manifests itself as a newly hatched larva rn a pond or lake or river. If all goes well, the larva soon finds and enters the body ofa suitable speciesoffresh-water snail. It is there transformed into an aggregation ofreproductive spores,and these, after several weeks of ceaselessproliferation' emerge from the snail as a multitude of tadpole-likewrigglers. The wrigglers must promptly find a suitable animal host, and one host to which they have irrevocably adapted themselves is man. Wrigglers fortunate enough to come upon the necessaryhost attach themselvesto the skin, discard their tails, and (with the help of a tissue-dissolving enzyme) burrow through the epidermal barrier' Penetrationusually takes about twenty-four hours and is unperceivedby the host' Once through the skin, the wrigglers launch themselvesin the current ofthe peripheralblood vesselsand are carried along to the veinsand through the heart and into the systemiccirculation. The survivors of this intricate voyage (which may take severaldays) then gather in the richly nutntious blood that flows from the gastro-intestinaltract to the liver and beyond. There they grow to maturity (about an inch in length for the females,and less than half that for the males),and mate. They then retire to the comfort of a tiny backwater vein, where the female, still enclosedin the male's embrace,deposits-for incubation and eventual excretion with the body's wastes-the first of an almost infinite number of eggs. It is not unheard of for a female schistosometo live and breed for thi rty years. The site that a schistosomechoosesfor its eggs is not a haphazardchoice. It is predeterminedby the speciesof worm' There are three species to which man is warmly hospitable-Scilstosoma hoemotobium, Schistosoma mansoni, and Schistosoma urilaponicum.
