16,1 Haughwout and Horrilleno: Intestinal Parasites 57 
it is interesting to note the behavior of filarial infections in 
Filipinos. The parasite is very frequently found in some parts 
of the Southern Islands, but symptoms such as chyluria and 
elephantiasis are so rare as to attract considerable attention 
when they occur. Furthermore, in Filipinos as in many other 
Malayan peoples the larval forms show no diurnal periodicity, 
but usually may be detected in the blood throughout the twenty- 
four hours. 
Perhaps the answer to these questions could be found were 
v/e able to turn back the pages of the Book of Time and discover 
when the Filipinos or their ultimate ancestors first became in- 
fected with nematodes. We are rather inclined to regard these 
strange phenomena as indicative of a high degree of adaptation 
between certain nematodes and that congeries of people spoken 
of as the Filipino people. In that event we should expect that 
the association of the hookworm, Filaria, and their Philippine 
hosts had dated back to very remote times. If it were possible 
approximately to fix the date of entrance into the Philippine 
Islands of the New World hookworm, we .might derive some in- 
teresting data from a comparative study of the clinical manifes- 
tations accompanying infections with Necator and Ancylostoma. 
It seems worth while to mention only one of our cases of 
hookworm infection, and we leave it to our readers to extract 
such information from our tables as may interest them. 
This was the case of a girl (No. 26), 13 years old, from Batangas Prov- 
ince. Her stool was positive for “Blastocystis,” Spirochmta eurygyrata, 
Trichomonas, and hookworm. When her faeces were first examined on 
August 27, hookworm ova were found in considerable numbers ^n the first 
fresh preparation that was made. 
The clinical diagnosis was hysteria, ancylostomiasis, and ascariasis. We 
never discovered any evidence of Ascaris infection. The child was stunted 
as to growth and showed no signs of puberty. Mentally she seemed bright 
enough, but she was morbid and melancholic at times and when some 
little attention was shown her she, to use the expression of one of the 
physiciarfs on the ward, became “very sentimental.” After admission it 
was noted that the child, w'ho complained of pain in the upper abdomen that 
had persisted for five years, was pale and jaundiced. The total erythrocyte 
count was 3,280,000, and the hemoglobin 60 per cent. There were 12 per 
cent eosinophilic leucocytes. Polymorphonuclear neutrophiles numbered 
59 per cent, lymphocytes 28 per cent, and large mononuclears 1 per cent. 
Roentgen-ray examination gave no evidence of gall-bladder trouble or 
peptic ulcer, and the faeces were negative for occult blood. 
The patient suffered acute pain in the epigastrium of such severity 
that it was found necessary to administer morphine. Chenopodium treat- 
ment was started, but on September 19 the patient was still suffering 
severe pain notwithstanding that chenopodium had been given twice.
