vomited „bile", from time to time over a number of years, sometimes vomiting repeatedly in one day. The vomit was thin, greenish, hitter, usually containing some food and mucus. Anorexia was typical during this period, hut fever, diarrhoea or other symptoms, attributable to gastrointestinal disorders, did not occtir. The boy was emaciated from the early childhood on,and a „worm" of roughly 5 cm length was found in his stool. State at admission

: A sickly child of asthenic constitution. Laboratory findings

: RBC

: 3,5 million; WBC: 7400; Hb: 11,4 gm Ío\ ESR: 7 nun per hour. Differential white cell count: myelocytes:-; praemyelocytes: 4 i°\ neutrophils: 36 $; eosinophils: 6 jo

\ basophils: -; monocytes: 2 $; lymphocytes: 56 Urine

: protein: -; pus: ++; FBS: negative; urobilinogen:normal; sediment: 2-3 WBC and some amorphous granules. Parasitological examination of the stool

:Eggs of Trichostrongylus spp. (

Fig. 1 and 2) were repeatedly detected. The patient was given 25 mg per kg body weight thiabendazole (Mintezol, Merck, Sharp and Dohme) for 2 days. The therapy proved successful; subsequent repeated parasitological examinations were consistently negative. The condition of the child was assessed on January 6th, 1970. The parents of the child reported that there had been no complaint since he had been taken home, nor were symptoms detected at the time of examination. A decrease in eosinophil count (2 <fo) and the absence of parasite eggs in the faeces were considered the most relevant changes in laboratory findings. Summary

. The child, physically under-developed, was admitted on account of gastrointestinal complaints of some years' duration. Symptoms, described in the history,were possibly related to the parasitological findings. No alterations were found in any of the organs.
