Eccrine poroma localized in the second toe

Eccrine poroma is a rare adult benign adnexal tumor that originates in the excretory pore of the sweat gland. It is a small reddish lesion, protuberant, fleshy, and well-defined. It is located preferably in the palms of the hands and the soles of the feet [1]. Nevertheless, it may be found on any skin part of the body''s surface [2]. We report a case of eccrine poroma of relatively rare localization on the second toe of the left foot. The biopsy confirmed the diagnosis by objectifying the histological lesions corresponding with the poroma. The article aims to report an eccrine poroma located in an unusual location, surgical treatment, and follow-up.     

STUDIES ON TI-IE TYPES OF CORYNEBAC- TERI UM DIPHTHERIAE IN SHANGHAI

Anderson and his co-workers (1931 and 1933) by using a heated blood agar medium containing potassium telIurite described the existence of Gravis, Mitz''s and IntLlnnediate types of C. diphLheriae. Thcy further showed that a correlation existed between the types of organism and clinical severity. These important findings have now heen confirmecl hy many other workers. A review of the observations which have accumuIated xvith regard to the significance of diphtheria types from 1931-1935 was made by Cooper et al (1936). In a series of more than 6,000 cases of cIiphtheria gatherecl from many parts of England and Germany, they found ihat at least 95% of the strqins have ralien vvithin three principEil types as Gravis, Intcrmediate and Mitis. The Gravis strain has been i''ound tFie most virulent and cssociaLed with the highest case dcath rrite and the g-eatest incidence ufparzilysis. The Ti,termediate strP.ins are more nearly rclated to Gravis than to Milis in respect to their case death ratcjncl at least equal to Gravis in tcncl-ing to produce lLaerr.orrhagic phenomena: The Mitis strains are associated with mild infections and rarely cause cIeath. As reports continue to suggest that the frequency of distribu- tion of types of C. diphtheriac vary widely in different areas, as far as the authors are aware, no work has been done aIong this line in Shangnai and other parts oI China. The present paper is a study of the distribution of types of C. diphtheriae cultures isolatefl from one hundred cases of diphtheria in Shanghai during the period from October 1938 to March 1939.     

Zur Pathogenese der cutanen Idiosynkrasien

A SUGGESTIVE SKIN TEST FOR SUSCEPTIBILITY TO CHOLERA

Pfeiffer (1) initiated tbc studies on toxic substance derived from the cholera vibrio and found that filtrates of young broth cultures of the cholera vibrio were but sliglitly toxic, whereas the dead bodies of carPfully killed agar cuItures were fatal to guinea pigs even in small quantitics. In consequence, he regarded the cholera poison as consisting chiefiy of an endotoxin. Fairbrother (2) stated that the substance of the cbolera vibrio which gave rise to protection of animals was intimatcly connected with the body protoplasm and that it''was heat stable at l(X)o C for one hour. This antigen was present only in small quantity in the supernatant fluid of a 24-hour broth culture after ccntrifugalization. This opinion of the endotoxic nature of the cholera poison is, howcver, not shared by all workers. Metch- nikoff, Roux and Taurelli-Salimbeni (3) succeeded m producing death in guinea pigs by the introduction into tbeir peritoneal cavities of cholera cultures enclosed in colloidin sacs. Brau and Denicr (4), Kraus (5) and more recently Hahn and Hirsch (6,7,8,9,) claimed tbat they have succeeded not only in the demonstration of a soluble toxin in alkaline broth cultures of cholera vibrio, but also in the production of true antitoxins. Bail (10) using a special strain of cholera vibrio obtained watery extracts which produced antitoxin, which workcd according to the law of multiple proportion. Takano (11) compared various solutions obtained by washing eitber killed or living cholera vibrios and the residual bacterial bodies. He did not find any differ- ence in the various immunological duced in guinea pigs with these reactions and the symptoms pro- solutions, and be came to the conclusion that it was difficult to distinguish in cholcra between the exotoxin and the cndotoxin. Although opinions as to the nature of poisonous action of the cholera vibrio arc still divided, there is general agreement that a toxic substance exists in cholera cultures.     

AN UNUSUAL CASE OF OVARIAN CYST

The following case seems sufficiently unusual to be worthy of record. The patient. a young woman, came to the Swatow Mission Hospitalitl October 1931. complaining of a lump in the abdomen of several months duration She stated that she had sulfered occasional pain of a colicky nature some time ago, but lately ktd been quite free of pain. She dicl not give a very concise history. but on being questioned after operation. denied that she had ever sufiered any really severe pain. Menstraation was regular.
