696 THE ANIMAL PARASITES OF MAN 



and these do not abate till after the removal of the oxyuriasis. Some 

 authors speak of an oxyuriasis cutanea (Majochi 1 ), in the more 

 limited sense of a dermatitis intertriginoides. So far five such cases 

 have been recorded, one each by Szerlecky, 2 Michelson, 3 Majochi, 4 

 Barbagallo 5 and Vignolo-Lutati. 6 Szerlecky's case was that of 

 a young woman with intertrigo over the thighs (the skin was covered 

 as if with leather) ; Michelson's case was that of a boy, aged 13, 

 with intertrigo on the skin of the genito-crural fold, of the scrotum 

 and of the thigh ; Majochi's was that of a man, aged 38, with the 

 same localization ; Barbagallo's case was that of a boy, aged 14, 

 in whom the dermatitis extended to the hypogastrium (rhagades on 

 the scrotum) ; and Vignolo-Lutati's case was that of a man, aged 24, 

 with intertrigo of the peri-anal and perineal Region, of the scrotum 

 and the inner side of the thigh. 



On leaving the gut, Oxyiiridce frequently migrate to the stomach, 

 to the oesophagus, to the mouth, to the nasopharyngeal cavity, and 

 into the nose (Zarniko 7 ) (the localization in the nose has been 

 referred to as associated with the possibility of auto-infection see 

 p. 695 as to the development of embryos from the ova in the 

 moist nasal mucosa). Still the occurrence of Oxyuridcc in the nose 

 is among the greatest of rarities. Chiari 8 records the case of a girl, 

 aged 14, who suffered from pains at the root of the nose and in 

 the left side of the forehead; female specimens of Oxytiris vermicularis 

 were evacuated from her nose on several occasions. A similar case 

 is recorded by Hartmann 9 ; it was that of a girl, aged 13, with 

 epileptiform convulsions and psychic disturbances ; numerous 

 Oxyurides frequently escaped from her nose. With their departure 

 the symptoms of irritation of the central nervous system also dis- 

 appeared. Rheins 10 records a case, that of a woman, in which a 

 specimen of Oxyitris vermicular is was discharged from the right 

 nostril during the act of sneezing. Proskauer 11 found in the nose 

 of a woman, aged 30, a conglomerate of from fifteen to twenty very 

 small worms which proved to be Oxyuris embryos. 



The diagnosis of oxyuriasis is not difficult to make, as the trouble- 

 some sensations in the anus and about the genitals necessarily suggest 

 the presence of Oxvnridcv. As a rule the small white worms are
