The article presents information on the paper "Causes in 2741 Cases of Occupational Dermatoses," by J.V. Klauder that appeared in the 1958 issue of the "Journal of Investigative Dermatology." Researchers observed that skin manifestations as direct or indirect sequel of accidents and injuries accounted for 22-1%. Sensitizing substances were responsible for 15-9% and the wet nature of the work for 15-2% malonate ointment.

The article presents information on the paper "The Inhibition of Perspiration by Means of the Topical Application of Malonic Acid Salts," by A. Rostenberg and E.J. Gonzalez that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Researchers concluded that since malonate ions competitively inhibit the enzyme succinic acid dehyrogenase, it was not unreasonable to try a 20% sodium malonate ointment.

The article focuses on a paper regarding the disease melanotic whitlow. Melanotic whitlow probably represents some 3% or 4% of all melanomas. Approximately 80% of the patients are about equally distributed among the fifth, sixth and seventh decades of life. Patients with this form of melanoma are older than patients with other forms of melanoma. There is no significant difference in incidence between the sexes. The lesion most frequently involves the upper extremity, especially the left thumb, two-thirds of the lesions involve either a thumb or a great toe.

The article presents information on the paper "Simple Tests for the Demonstration of the Low Free Amino Nitrogen Content in Psoriatic Scales," by P. Elesch and E.C. Jackson Esoda that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Researchers concluded that if one wants to distinguish between normal and pathologic scales, one can chromatograph a drop of watery extract with a phenol water mixture and develop it with ninhydrin. While psoriatic extracts show very faint spots or none at all, extracts of callus develop a marked pattern.

The article presents information on the paper "Determinations of Squalene in Sebum From the Forehead of Patients with Skin Cancer," by H. Sobel, J. Makmorstan, E.T. Wright and E. Garcia that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Squalene is supposed to neutralize the carcinogenic properties of methylcholanthrene. The normal secretion from the forehead is 1.4-7.3 mg per sq cm averaging 5.11 in 22 subjects. Eighteen patients with basal-celled growths averaged 10.58; while the 12 with squamous growths averaged only 2.86.

The article presents information on the paper "Comparative Studies of Special Media for Identifying Candida Albicans From Other Candidas and Molds," by Barham Sina and P. Reiss that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Researchers observed that no species of Candida other than albicans produced chlamydospores on either rice infusion agar, cornmeal agar or Bacto-chlamydospore agar. Chlamydospores appeared on rice infusion agar in all of the 30 cases examined but failed 7 times in each of the other two media.

The article presents information on the paper "Examination of the Epidermis by the Strip Method: The Melanocytes During a Period of Forced Regeneration," by P.J. Kropp that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Researchers observed that while stripping provokes an outburst of mitotic activity in the basal layer, it has little or no effect, in contrast with that of thorium X, on the melanocytes.

The article presents information on the paper "The Dermatologist as an Individual: An Appraisal of Cultural Trends" by M.E. Obermayer that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Medicine was once a learned profession. The article deplores the tendency for the dermatologist to become little more than a distributor of pharmaceuticals.

The article presents information on the paper "Qualitative and Quantitative Data on Melanocytes in Human Epidermis Treated With Thorium X," by R.J. Staricco that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Researchers found that in skin reacting mildly to thorium X, the melanocytes exhibit increased activity, send out long processes and may even ascend the outer layer and be desquamated, but they do not increase numerically out of proportion to the basal cells.

The article presents information on the paper "Melanocyte Distribution in Forearm Epidermis of Freckled Human Subjects," by A.S. Breathnach that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Researchers found that there are little more than half as many melanocytes, at any rate dopa-positive ones, in the freckles than in the surrounding skin. Thus it will be necessary to study the epidermis of likely-to-be-freckled children under 2 years old in order to ascertain if this unequal distribution is congenital or acquired.

The article presents information on the paper "Seborrhoeic Keratoses: Pseudoepitheliomatous Hyperplasia," by Lyon Rowe that appeared in the 1957 issue of the "Journal of Investigative Dermatology." The paper describes some difficulties in the clinical and histological diagnosis of seborrhoeic keratoses, in particular that of avoiding the diagnosis of squamous carcinoma arising out of one.

The article presents information on the paper "The Growing Hair Roots of the Human Scalp and Morphologic Changes Therein Following Amethopterin Therapy," by E.J. Van Scott, R .P. Reinertson and R. Steinmuller that appeared in the 1957 issue of the "Journal of Investigative Dermatology." Researchers observed that in tufts of about 50 hairs plucked from normal scalps by means of a surgical needle holder, round about 85% are found to be in the anagen phase. Two weeks after an intravenous dose of amethopterin, a sharp constriction could be seen in a high proportion of anagen hairs corresponding to an inhibition by the drug of mitosis in the hair bulb.

The article focuses on a paper about the detection of radiation effects on hair roots of the human scalp. The paper presents an account of the effect, on the hair bulb and keratogenous zone of hairs in the anagen phase, of exposure of the scalp to x-rays and to electrons emitted from a Van de Graaff generator.

The article focuses on a paper about periodic acid-schiff positive material accumulating within the lumen of eccrine sweat glands. In the course of an experiment in which part of the skin of the back was treated with chlorinated naphthalene and another part, as a control, with acetone or naphthalene in acetone, there was noticed in sections of both areas in two Black subjects periodic acid-Schiff positive material in the lumina of eccrine ducts.

The article focuses on a paper cadmium sulphide suspension in seborrhoea capitis. This is successful in 79 out of 84 cases of seborrhoea capitis.

The article focuses on a paper about primary irritant activity of barrier creams. Forty-eight-hour patch tests were performed on 300 subjects, mostly suffering from eczema, with 6 different barrier creams and with 13 other materials including nickel, chrome, procaine, paraphenylene diamine and turpentine. The barrier creams provided most of the positive reactions: one oil-resistant type in 50% of the subjects tested. The author points out that the patch test involves a more severe exposure than the usual protective inunction and urges that in spite of their irritant character, now revealed, they have been used with great success in the prevention of industrial dermatoses.

The article focuses on a paper about in vitro invasion of hair by dermatophytes. The attempt to produce in vitro invasion of the hair shaft by the continuous shaking culture technique was successful in hair obtained from only one of 4 young girls.

The article focuses on a paper about melanocyte counts on human forearm skin. The author's material, obtained in all 10 cases from the proximal part of the medial aspect of the forearm of healthy white males, yielded higher counts than those of other investigators.

The article focuses on a paper about histology and cytochemistry of human skin. It has been supposed that specific cholinesterases are peculiar to the postganglionic fibres of the parasympathetic nervous system, but their presence in the sensory nerve plexus surrounding the hair follicle is here demonstrated by a reaction with acetylthiocholine iodide that can be abolished by treatment of the material with physostigmine.

The article focuses on a paper presenting the classification of Candida albicans. Incubated on human-blood agar plates at 37° C. for 48 hours in an atmosphere containing 6-8% carbon dioxide, Candida albicans tropicatis and stellatoidea each produce colonies differing sufficiently in appearance to make recognition possible.

The article focuses on a paper presenting an electron microscope study of thin sections of human skin. The tonofibrils and intercellular bridges of the rete appear in this study to represent a fibrous keratin precursor which in the stratum granulosum changes into the keratin of the horny layer, the larger and more irregular granules of keratohyalin representing a by-product.

The article focuses on a paper presenting studies on vascular skin responses in atopic dermatitis. A rough psychiatric classification of patients with flexural prurigo would divide them into the extroverted and the introverted. The former give a normal response to intradermal histamine, in the latter the flare fails to appear, but in both the reaction may change under the influence of psychiatric treatment or adventitious emotional stimulus.

The article focuses on a paper showing results of patch testing with rubber antioxidants and accelerators. The author uses a routine series of patch tests with monobenzyl ether of hydroquinone, phenyl beta naphthylamine, mercaptobenzothiazole, tetramethylthiuram monosulphide and diphenylguanldine.

The article focuses on a paper about the rationale for the treatment of lupus erythematosus with antimalarials. The authors recommend treatment with a mixture of chloroquine and hydroxychloroquin, of each 2 parts and quinacrin one part.

The article focuses on a paper about allergic sensitization to adhesive tape. The paper is a discussive and fanciful exploration of the possibilities of allergy to the various forms of zinc oxide plaster.

The article focuses on a paper presenting a re-evaluation of taxonomic status of Trichophyton equinum. Trichophyton equinum has been isolated from cases of human ringworm, but it will not grow vitro on horse, mule or donkey hairs unless nicotinic acid is supplied. Thirty-three strains of Trichophyton equinum obtained from various sources displayed this specific requirement, which is not shared by other dermatophytes.
