Biochemical and physiological parameters on the healthy skin surface of persons with candidal intertrigo and of persons with tinea cruris.

Biochemical and physiological tests were carried out on the skin surface of 20 patients with candidal intertrigo and 27 patients with tinea cruris. In all patients the test areas were free of efflorescences. The same tests were performed in 39 and 27 resectively healthy test persons of the same age and sex. The following striking findings came to light: 1. There was a significant decrease in the percentage amount of squalene in the skin surface lipids of the moniliasis group as compared with the control group. 2. There was a significant decrease in the reducing substances in the so called water solubles obtained with the phenol sulfuric acid method in the moniliasis group. The same results were obtained when only those moniliasis patients who were definitely not suffering from diabetes mellitus were taken into account. This is presumably a question of a reduction in the bound carbohydrates. 3. There were significantly more amino acids extractable from the skin surface of the tinea cruris patients than of the control persons. These results point to important predisposing factors for the susceptibility to candidal intertrigo and tinea cruris respectively.

[Intertrigo--a therapeutic problem circle].

Intertrigo is an inflammatory dermatosis involving the body folds. Predisposing factors include constant friction opposing skin surfaces, obesity, sweating and occlusion. Colonization with bacteria, yeast and dermatophytes may exacerbate the dermatosis. Irritant antiseptics may aggravate intertrigo and provoke an allergic contact dermatitis. Treatment consists in careful drying the skin. Antimicrobial agents topically applied may be helpful. Predisposing factors should be corrected carefully.

Problems with clinical trials in general practice--a double-blind comparison of cream containing miconazole and hydrocortisone with hydrocortisone alone in the treatment of intertrigo.

A double-blind comparative study between 1% hydrocortisone cream and a combination of 1% hydrocortisone cream and 2% miconazole cream has highlighted some of the problems with this type of research in general practice. The collection of adequate patient numbers within a predefined time scale proved a major problem. However, the study demonstrated the safety and efficacy of both these preparations in the treatment of intertrigo.

Double-Blind Method

Intertriginous drug eruption.

Presented are two patients who developed an unusual, and as yet unreported eruption due to amoxycillin. They exhibited an eruption confined to the intertriginous areas, which mimicked intertrigo. Although drug eruption can mimic a variety of idiopathic skin diseases, intertrigo is easily distinguished from drug eruption and has not been mentioned in the differential diagnosis of this reaction. It is suggested that drug reactions should be considered in the differential diagnosis of intertrigo, in particular of atypical and therapy-resistant cases. Early detection of these cases has practical importance since the elimination of the causative drug is essential for therapy success. Case 2 showed a response of the toxic epidermal neurolysis (TEN) type, which could have been very severe and dangerous had the diagnosis not been made in an early stage before the development of generalized TEN.

Dermatoses--an occupational hazard in the canning industry.

Despite the recognition that occupational dermatitis is extremely common, few data exist on the prevalence of skin disorders in South African industry. A cross-sectional prevalence study among 686 female workers in a canning factory in the western Cape showed high rates of dermatoses--in particular, chronic paronychia, intertrigo and dermatitis of the hands. A statistically significant association was found between exposure to 'wet work' in the industry and the prevalence of chronic paronychia and intertrigo. Age was also found to be associated with these dermatoses, irrespective of duration of service. The prevalence of dermatitis of the hands was increased among high-exposure workers, but not significantly. Dermatoses are an important occupational hazard in the canning industry, and there is a need for improved preventive measures.

[Clinical aspects, epidemiology and economic impact of foot epidermomycosis in an industrial milieu].

Fungal infections of the feet are very common in some professions. This has been particularly studied in coal mine workers up to 50 p. 100 of whom were found to have dermatophytosis of the feet. The purpose of this study was to determine the clinical, epidemiological and evolutive characteristics of interdigital and plantar intertrigo of the feet among people working in a coking plant, a potash mine and a motorcar factory. We have also evaluated the cost of treatments in relation to their immediate effectiveness and their preventive effects on relapses. Initially, 208 workers entered the study: 84 (40.7 p. 100) had a mycotic infection (M) and 124 (59.3 p. 100) presented with a non-mycotic (NM) inflammation between the toes and on the soles, characterized by maceration of the skin, hyperhidrosis and bromhidrosis. Change in the lesions under treatment were subjected to statistical analysis. In both M and NM groups the workers were allocated by randomization to a double-blind treatment consisting of: group M: either 2 p. 100 miconazole powder or talcum powder with 2 p. 100 salicylic acid and boric acid; group NM: either 2 p. 100 miconazole powder or ordinary talcum powder. Each subject was seen on at least two occasions after 3 and 12 months of daily foot care and topical treatment. Mycological examinations in group M subjects showed that fungal infections of the feet were primarily due to Trichophyton mentagrophytes or to Trichophyton rubrum. A logistic regression analysis (BMDPLR program) of anamnestic and clinical data (table IV) led to a "mathematical model of the mycotic foot", characterized by 6 main parameters of statistically significant occurrence: a history of interdigital-plantar intertrigo, recurrent in 90 p. 100 of subjects in group M (significant association at 0.1 p. 100); a functional symptom, pruritus, present in 71 p. 100 of subjects with mycosis; the stronger, more disturbing the pruritus, the greater the probability of it being of fungal origin (significant association at 0.1 p. 100); 4 physical signs: lack of maceration (0.1 p. 100), lesions limited to the interdigital spaces and respecting the soles (0.1 p. 100), presence of interdigital fissures (0.5 p. 100) and vesiculation (2.5 p. 100). When the respective diagnostic values of these elementary symptoms were considered, it appeared that their various combinations might have predictive values which could be calculated.(ABSTRACT TRUNCATED AT 400 WORDS)

[Chester-Erdheim's disease. A case].

We report the 32nd case of a multivisceral form of Erdheim-Chester disease. This exceptional pathology is a diffuse xanthogranulomatosis which comes within the scope of histiocytosis. The originality of this case is due to cerebral localizations and to the fact that some symptoms have been observed for a long time: diabetes insipidus, exophthalmos and stubborn intertrigo.

Classification of diaper dermatitis: an overview.

Several types of diaper dermatitis are discussed: generic diaper dermatitis is most common and involves a simple erythema and mild scaling of the gluteal crease, buttocks, thighs, and lower abdomen. Candidal diaper dermatitis involves clinically significant infection with Candida albicans and presents as a sharply marginated area of erythema with significant involvement of the anterior thighs, genital creases, abdomen, and genitalia. Noduloulcerative diaper dermatitis may develop in a small percentage of patients who have chronic diaper dermatitis, as large, raised erosions with rolled margins. The lesions are most noticeable on the prominent body parts-genitalia, abdomen, thighs, and buttocks. Infantile seborrheic dermatitis involves a distinctive pattern of inflammation that usually begins beneath the diaper as a sharply marginated area of erythema with satellite lesions. Within 1-2 weeks, lesions develop on the scalp, cheeks, arms, legs, and intertriginous parts of the body. Impetigo is common in the diaper area, particularly in the first 6 months of life and during the warmer summer season. The lesions are usually bullous and represent infection by Staphylococcus aureus. Folliculitis appears as small, perifollicular erythematous papules and pustules, usually on the buttocks, thigh and lower abdomen. It is common in the warm summer months and is usually caused by bacteria such as S. aureus. Intertrigo categorizes disease that does not fit into the above categories. Often the patient presents with simple erythema of the folds without pustules or induration. This probably represents irritation and low-grade infection. It is important for the clinician to be aware that many other diseases can have manifestations in the diaper area.(ABSTRACT TRUNCATED AT 250 WORDS)
