MISCELLANEOUS CASES OF MYL\SLS 307 



of the urinary tract <>f a woman rather than that of a man. The 

 case recorded by Chevril indicates fairly clearly how the female 

 urinaiy tract may be infected by the continued or prolonged 

 exposure of the organ. As the flies are frequently found in bed- 

 rooms the infection of both sexes during hot weather is sometimes 

 rendered possible. Infection is chiefly facilitated by uncleanliness 

 and carelessness. * 



The whole subject of the relation of these flies to myiasis of 

 the intestinal and urinary tracts is one which has received com- 

 paratively little attention. Certainly not the attention it deserves 

 on account of the complications incident to such infections that 

 may arise. 



Miscellaneous Cases of Myiasis. 



In addition to the aforementioned cases of myiasis, which have 

 been ascribed in most cases to definite species of dipterous larvae, 

 medical and other literature contains numerous references to the 

 occurrence of living dipterous larvae, or maggots in human beings \ 



The remarkable occurrence of dipterous larvae in the anterior 

 chamber of the human eye has been recorded by Ewetzky and 

 Kennel (1904) and also by Thomas and Parsons (1908). I was 

 enabled, through the kindness of my friend Dr Shipley, to examine 

 sections of the latter case which showed the larvae in situ. 

 Portchinsky (1913) has described and figured the occurrence of 

 the larva of Hypoderma bovis, the ox warble, in the anterior 

 chamber of the eye which it would appear to have reached by way 

 of the nasal sinus. The occurrence of dipterous larvae in the 

 orbit is also recorded by Keyt (1900) and Gann (1902). 



Cleland (1912) has given a number of Australian records. 

 Two cases are given of the occurrence of dipterous larvae in the 

 ear; in 1865 twenty maggots were removed from the ear of a 

 small boy at Castlemaine, Victoria {Austr. Med. Journ. Vol. x. 

 p. 95). Dr G. H. Salter of Ballan, Victoria, described {Austr. 



1 Since the above was written Graham -Smith (1913) has given an excellent 

 re\aew of Myiasis caused by non-blood-sucking flies. In addition, the following 

 authors have cited cases: Francaviglia (1912), Balzer, Dantin and Landesmann 

 (191.3), Surcouff (1913). Zepeda (1913), Neiva and Gomes de Faria (1913), de Moura 

 (1913), Heckenroth and Blanchard (1913), Sergent (1913), Edgar (1913), Field (1913), 

 Hall and Muir (1913), Candido (1913), Miller (1910).
