A case of impetigo herpetiformis associated with profound hypocalcemia secondary to idiopathic hypoparathyroidism is reported. This clinical observation and the review of similar cases in the literature recall that this rare and severe skin disease related to psoriasis can be the first manifestation of hypoparathyroidism and responds very well to the calcium reloading.
Sulfonamides can be used in the treatment of impetigo with vastly increased safety and with more effectiveness in powder rather than ointment form when combined with urea powder in a ratio of approximately three parts of sulfonamide to one of urea. Of 701 patients treated with such a mixture, 95.6 per cent were cured within a week. The only complication was local dermatitis which occurred in 0.57 per cent of patients. This compares favorably with results obtained with newer and expensive drugs which usually have the disadvantage of being used in a greasy vehicle. The low incidence of sensitivity reaction to the sulfonamide-urea powder is perhaps ascribable in part to the avoidance of a greasy vehicle.
Impetigo is a common skin infection in children. If not treated promptly, it can spread rapidly through a student population and become a significant health problem. Whereas uncomplicated, localized lesions typically are treated with topical mupirocin, widespread infections involving multiple pathogens require systemic treatment with a cephalosporin or a beta-lactamase-resistant antibiotic.
A new topical antibiotic, mupirocin, has been found to be as effective as erythromycin for the treatment of impetigo, but concerns about its expense have been raised. This controlled clinical trial sought to compare the cost-effectiveness of erythromycin (E) and mupirocin (M). Ninety-three children, aged 3 months to 16 years, were randomly assigned to receive 10 days of oral erythromycin (n = 46) or topical mupirocin (n = 47). Costs and effects were measured through structured interviews. Cost per case differed significantly by group (E = $56.85; M = $62.30; P less than .05) due chiefly to extra visits and medication changes needed by those treated with mupirocin. Erythromycin and mupirocin were equally effective. The likelihood of side effects (E = 43%, M = 22%) approached significance (P less than .07); those treated with erythromycin were willing to pay more for a different medicine to avoid the side effects experienced (P less than .05). Working parents and school-age children were more likely to alter their daily activities when the patient was taking erythromycin (P less than .04). Compliance and parental satisfaction did not differ by treatment group; however, parents of children treated with erythromycin were more likely to prefer the alternate drug regimen. It is concluded that the type of medication prescribed can be based on parental preference because the increased cost of mupirocin is offset by increased side effects and number of schooldays and workdays lost with erythromycin.
Two clinical cases of Hebra's impetigo herpetiformis are described. This rare dermatosis is regarded as a variant of pustular psoriasis and is difficult for differential diagnosis.
Seventy seven cases of impetigo were studied in children. Group A beta hemolyticus Streptococcus was the only bacterial agent isolated from 25 culture samples, Staphylococcus aureus from 6 and both agents from 39 cases. Cultures were negative in 7 children. The clinical response to treatment with penicillin G benzathine, crust removal and skin cleansing was satisfactory in 93.5% of the cases, nonresponders (6.5%) were satisfactory treated oral with cloxacillin.
Two hundred cases of impetigo contagiosa were studied bacteriologically. Along with the usual staphylococci and streptococci, gram-positive diplococci were isolated in pure cultures in thirty-seven cases. Ninety-six cases were submitted for sensitivity tests to several antibiotics; the results are discussed.
Because the effectiveness of topical antimicrobials in the treatment of ecthyma, impetigo, and pyoderma is not well established, the US Food and Drug Administration has recently proposed guidelines for tests of topical antimicrobial efficacy in primary skin infections. The guidelines require both comparison with the agent's base and microbiologic documentation of efficacy. These guidelines were followed in this double-blind, eight-day evaluation of impetigo/ecthyma treated with mupirocin, a new agent that is only active topically. All cultures, before and after therapy, were taken using swabs dipped in neutralizing broth plus 10% fetal bovine serum to minimize antimicrobial "carry over" to the culture plate. Staphylococcus aureus, which was isolated from 94% of the patients before therapy, was eliminated in 88% of the mupirocin-treated patients and 47% of the vehicle-treated patients. Group A beta-hemolytic streptococci were eliminated in 100% of the mupirocin-treated and 0% of the vehicle-treated patients. To our knowledge, this is the first topical antibacterial treatment for primary skin infections proved superior to its vehicle using the proposed US Food and Drug Administration guidelines.
A patient is presented who developed impetigo herpetiformis-Hebra for the first time in her 19th year, one month before a normal delivery. The child is alive and in good health. The second time the disease appeared after three years, in the 20th gestational week of the woman's new pregnancy when because of her bad general condition, pronounced skin changes, and a very high temperature (up to 41 degrees C) the artificial interruption of pregnancy was carried out by using Prostin 15M-Upjohn. She was given a total of 6 ml Prostin in two doses, and the abortion period lasted 17 hours. After abortion, the acrocyanosis of the feet and wrists appeared (after the application of Methergin). A general and symptomatic therapy was applied and the patient recovered in 24 hours. Skin and her general condition improved, and after 10 days she was discharged, and since that time (April 1984) she has had no symptoms of the disease.
A double-blind clinical comparison of cefadroxil granules (CDX) and a long-acting preparation of cephalexin granules (L-CEX) was conducted in the treatment of impetigo in children. The long-acting cephalexin preparation was composed of 3 parts of granules soluble in the stomach and 7 parts of those soluble in the intestine. Drugs were administered at 3 different doses depending on the body weight of patients (Group I: less than 10 kg, Group II: between 10 kg and 20 kg, Group III: over 20 kg). Overall clinical evaluation by attending doctors: CDX group scored slightly better but not statistically significant results. Evaluation of usefulness: CDX group scored slightly better but not statistically significant results. Partially standardized evaluation: CDX scored statistically significantly higher points in the evaluation of total cases and Group II on Day 5, and Group II on Day 7. Cumulative points through Day 5 and Day 7 were not statistically significant. Follow-up evaluation by attending doctors: CDX group got a better result in total cases and Group II on day 3, and in total cases on days 5 and 7. Otherwise there was no statistically significant difference. Incidence of side effects was not significantly different between the 2 drug groups. As shown in Fig. 1, CDX was administered on rising in the morning, after lunch, and at bed time whereas L-CEX was given on rising and at bed time when the patients were relatively in fasting condition. This may have reduced the expected merit of L-CEX and some reserve is required in the interpretations of the results shown herein.
The growing incidence among newborns of B-streptococcal diseases has been accompanied by the appearance of less common findings, such as Impetigo neonatorum bullosa. The pathological pattern is described. Brief reference is made to literature.
Impetigo herpetiformis was diagnosed in a primigravida woman on clinical, laboratory, and histopathological grounds. This disease should be considered as a rare and serious variant of generalized pustular psoriasis. After initiating prednisone therapy, antepartum registration of fetal heart rate patterns appears necessary to evaluate fetal well-being. Subsequent pregnancies of the patient were not recommended.
One hundred children with a clinical diagnosis of Impetigo are presented. Seventy of them were bacteriologically studied. The sign-symptomatology is that usually described in this type of affection. Streptococcus was the principal bacterium involved and predominated in the youngest patients. Males were more frequently affected. There were no complications which could be attributed to this pathology either by local extension or by immunological involvement.
We found that mixed organisms of S.aureus and GABHS were the most common cause of impetigo in children in our study; that, of the two regimens evaluated, cloxacillin is the most effective treatment; that penicillin is equally effective in cases of mild to moderate forms and may be preferred on the basis of cost-effectiveness.
Impetigo herpetiformis (IH) is a rare pustular dermatosis with unknown aetiology, typically occurring during pregnancy. Based upon a similar clinical and histological presentation, i.e. spongiform accumulation of polymorphonuclear leucocytes in the stratum corneum, several authors consider IH as a variant of generalized pustular psoriasis (GPP), while others state that IH is a separate entity. Skin-derived antileucoproteinase (SKALP) is a strong and specific inhibitor of human leucocyte elastase (HLE) and proteinase 3, two neutral proteinases that have been implicated in leucocyte migration and tissue destruction. Previously, we reported decreased SKALP activity in pustular forms of psoriasis compared with plaque psoriasis. In this study we present a case study of a patient with IH, where SKALP activity was measured using biochemical and immunochemical techniques. Epidermal scales and sera were collected during the course of the disease. Comparison was made with three patients with GPP and six patients with plaque psoriasis. Initially, anti-HLE activity in epidermal scales of the patient with IH was comparable with values in patients with GPP, i.e. decreased compared with plaque psoriasis. During the course of the disease, anti-elastase activity dropped to undetectable levels, concomitant with the appearance of free elastase activity. This finding suggests a total saturation of epidermal anti-HLE activity. Low levels of SKALP, presumably complexed with HLE, could be measured immunochemically in scale extracts. Serum levels of total SKALP correlated with the disease activity. We suggest that a reduced amount of epidermal SKALP contributes to an imbalance between elastase and its inhibitor, resulting in the formation of epidermal pustules. This mechanism of pustule formation could apply both to GPP and IH, suggesting a final common pathway in the pathogenic mechanisms of IH and GPP.
Impetigo herpetiformis is a rare pustular disorder that occurs primarily in pregnancy and is often associated with hypocalcemia. The onset commonly presents in the last trimester of pregnancy; the condition may persist until delivery and it rarely continues in the postpartum period. There is an increase in morbidity and mortality for the mother and the fetus. As a result, immediate diagnosis and treatment is crucial. The purpose of this article is to delineate the clinical picture of this disease, its treatment, and the effect on the mother and the fetus.
Impetigo herpetiformis (IH) is a rare pustular dermatosis that shares striking clinical and histological similarities to generalized pustular psoriasis. The case of a 26-year-old primigravida with IH progressing in the 30th week of her pregnancy is presented. The peculiarity of our presentation relies on the reappearance of the disease postpartum. Monthly exacerbations during menstruation lasted for 7 years. Some probable clues regarding the pathogenesis of IH are suggested.
