In four medical centers, 40 patients with keratinizing dermatoses were treated with topical tretinoin (vitamin A acid) 0.1% cream and salicylic acid 2% cream in a short-term, double-blind study. Tretinoin was the more effective treatment for several of the keratinizing dermatoses with the exception of palmar-plantar hyperkeratosis, for which it was not effective in the concentration and method of application used. The most striking clinical responses occurred in patients with lamellar ichthyosis and ichthyosis vulgaris. Local adverse reactions-chiefly pruritus, erythema, burning, excoriation, and irritation-were not severe and could be controlled by modification of the treatment regimen.

Ten patients with psoriasis were treated for three days with salicylic acid ointment with vaseline vehicle. In all patients the serum concentration of salicylic acid increased systematically and the concentration depended on the amount of ointment used and on psoriasis form. Only in one case of exudative psoriasis the level of salicylic acid reached the value causing intoxication, and produced a diffuse inflammatory erythema with itching. The treatment caused no changes of biochemical indices.

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)

In this study a combination of clinical and experimental investigations demonstrates the antiproliferative effect of the coal tar-containing preparation Berniter. From a concentration of 70 micrograms/ml onwards (= 0.35 micrograms coal tar/ml) Berniter inhibits DNA synthesis of transformed human keratinocytes in vitro. The growth inhibiting effect is reversible up to the ED50 concentration (257 micrograms Berniter/ml = 1.3 micrograms coal tar/ml). The tar-free vehicle has no identifiable effect on the proliferation of the cells at a concentration of 260 micrograms/ml. However, at higher concentrations (ED50 = 1023 micrograms/ml) the vehicle also inhibits cell growth, this inhibition being irreversible. The effect of Berniter and the tar-free vehicle on amino acid metabolism corresponds with the reduced growth rate. The ED50 concentrations (331 micrograms/ml for Berniter and 1445 micrograms/ml for the tar-free vehicle) are higher than those in the investigation of the proliferation. The clinical trial was performed in two groups of 12 and 11 patients, respectively, suffering from Psoriasis capillitii. After 3 days' topical treatment of both groups with salicylic acid for scaling, one group was treated for 4 weeks with betamethasone-17-valerate (in the following briefly called Bet-17-v), as a commercial lotion. The other group received Bet-17-v initially for 3 days and was then treated for 4 weeks with Berniter. The 4 parameters used for evaluation (erythema, scaling, infiltration and itching) showed a more significant improvement in the Berniter group than in the Bet-17-v group. Subjectively, treatment with Berniter was assessed to be preferable.(ABSTRACT TRUNCATED AT 250 WORDS)

Efficacy and tolerance of an alcoholic solution containing 0.64 mg betamethasone-dipropionate plus 20 mg salicylic acid (Diprosalic Solution) were compared with an alcoholic solution containing 0,64 mg betamethasone-dipropionate in a 3 week double blind study in 100 patients with psoriasis and other steroid-responsive dermatoses of dry nature, comprising scalp and other hairy and non-hairy areas of the body. This double blind study was followed by a 3 week open study in another 100 patients with similar diagnosis, using Diprosalic Solution only. Although the therapeutic results of the double blind study showed no significant differences between both treatment groups, distinct advantages of the drug containing salicylic acid could be clearly demonstrated, such as: 1. More rapid onset of action, 2. rapid clearing of scaling, pruritus and inflammation, 3. these advantages are in compliance with the fact that topically applied salicylic acid softens keratin, loosens cornified epithelium and desquamates the epidermis, making the underlying layers more accessible to the antiinflammatory steroid.

Forty adult out-patients with erythematous squamous dermatoses of the scalp were treated in this 21-day double-blind study with an alcohol base lotion containing either 0.05% betamethasone-17,21-dipropionate, 2% salicylic acid, 0.05% betamethasone-17,21-dipropionate + 2% salicylic acid or their respective placebo. The four treatments were assigned randomly to the patients according to a 2 x 2 orthogonal factorial design. Changes in severity of redness, scaling, pruritus and size of lesions were evaluated. Since very few patients presented with excoriation and lichenification, these symptoms could not be ascertained. Results were assessed for significance by covariance analysis where initial status was used as regressor. A potentiation of the betamethasone-17,21-dipropionate activity by salicylic acid was observed for scaling. An additive effect was noted for redness and pruritus. According to the physician's global evaluation, patients treated with the combination drug showed a better evolution than those treated with placebo. The results suggest that addition of a keratolytic agent enhances the corticosteroid effect in the treatment of erythematous squamous dermatoses.

In a double-blind study on 22 patients affected by neurodermitis the action of two ointmes was studied. Both possess an activity in controlling the clinical and histological manifestations of the disease. Desoximethasone (red labelled tubes) is very usefull in controlling pruritus and, histologically, the epidermal component of the lesions. Bazalin (yellow labeled tubes containing fluocinolone acetonide 0.025%, leucobitupal 5% an salicylic acid 3%), has a higher antiscaling action a more intense activity on the dermal component of the lesions.

Allergic reactions to food colors have been known since 1958. Reactions to tartrazine, our example, include generalized pruritus, urticaria, angioedema, paresthesias, vomiting, migraine, rhinorrhea and nasal obstruction, coughing, asthma attacks and purpura. Many patients who are allergic to antiinflammatory drugs such as acetyl-salicylic acid and indomethacin show cross-reaction to tartrazine. Doses producing these reactions range from minimal amounts up to 750 mg. Symptoms appear after periods of time ranging from minutes to 6 to 14 hours. In view of these facts (some of which represent a threat to the patient's life), additives, colouring matter, etc, do not usually appear in product labels or specifications, or in handbooks or catalogues used in practice. We drew up a list of drugs which may contain food dyes and coloring matter, yellow No. 5. A letter was written to 233 laboratories of which 159 (68%) replied. 72 (45%) in the affirmative and 87 (55%) in the negative, 74 (32%) did not reply.

Androgen deprivation displays the mean therapy of advanced stage prostatic cancer, independently of palliative radiotherapy. The evolution to hormone-resistance status leads to a fatal tumor progression. High-dose fosfestrol (diethylstilbestrol diphosphate) has been suggested to circumvent hormone-resistance and to induce a direct cytotoxic effect. Sixteen patients with hormone-resistant prostate cancer were treated by continuous infusion of high-dose fosfestrol according to two schedules: 10 patients were included in a phase I trial of a daily escalating dose from 1.5 g/d to 4.5 g/d for 7 to 10 days. Six other patients were uniformly treated by 4 g/d for 3.5 h for 5 days. Between each course, patients received orally 300 mg/d fosfestrol and 200 mg/d salicylic acid. The mean age was 65 years (range 51-75). Mean number of courses was two (extremes 1-7). Toxicities: reversible weight gain was observed in five patients. One patient presented a pulmonary edema which was resolved immediately after diuretics. One patient and 9 patients respectively experienced grade III and II (OMS) nausea and vomiting. Transient perineal pruritus occurred in 5 patients. Responses: 15 patients were evaluable (one early death occurred on day 3 from tumor progression complicated by an intravascular coagulation disease). There were four objective stabilizations (NPCP criteria) lasting 2 m, 2 m, 5 m and 10 m respectively. Subjective improvement of pain was observed in five other patients. There was more than 50% reduction of PSA in eight patients. High-dose fosfestrol seems to have some objective activity with moderate toxicity and warrants further investigation.

1. A total of 512 consecutive paediatric hospital admissions of children 2 years old or less were evaluated to assess the extent and pattern of admission caused by suspected adverse drug reactions (ADRs). the proportion of suspected ADRs related to hospital admissions was 4.3%. 2. The organ-systems most commonly implicated were the central nervous system (40.5%), digestive system (16.7%), and skin and appendages (14.3%). Together, they accounted for 71.5% of admissions attributed to ADRs. The most common clinical manifestations inducing admission were convulsions (4 cases), dizziness (4), vomiting (3), and tremor, fever, itching and apnoea (2 cases each). 3. The four classes of drugs most frequently suspected in admissions due to ADRs were respiratory drugs (35%), anti-infective agents (25%), drugs active on the central nervous system (15%) and drugs used in dermatology (10%). The most common drugs related to ADRs were a combination of chlorpheniramine, diphenhydramine, phenylephrine, guaiphenesin and salicylic acid (4 cases), followed by fenoterol, adrenaline, paracetamol, DTP vaccine and antipolio vaccine (2 cases each). 4. There were no significant differences between children older and younger than 1 year (odds ratio 0.89; 95% CI 0.37-2.17) or between the sexes as regards hospital admittance due to suspected ADRs (odds ratio 1.94; 95% CI 0.72-5.42). 5. The results of this kind of study may be influenced by patterns of drug utilization. Nevertheless, the lack of specific studies of drug effects in young children makes it desirable to carry out pharmacoepidemiological studies in this age group.
