Topical all-trans retinoic acid (RA) induces an early, coordinated increase in RA-inducible skin-specific gene/psoriasin and cellular RA-binding protein II mRNA levels which precedes skin erythema.

Separation of specific and nonspecific "irritant" effects of topical all-trans retinoic acid (RA) is a key to understanding the mechanism of retinoid action in skin. Cellular RA-binding protein (CRABP) II has been found to be a marker of RA activity in human skin. We have also previously identified a skin-specific gene (RIS-1/psoriasin) which is rapidly induced in human skin treated with RA. Here we compared the kinetics and time-course of RIS-1 and CRABP II gene activation by RA, sodium lauryl sulfate (SLS), a classical irritant, and their vehicle (VH), using a quantitative reverse transcription polymerase chain reaction. RIS-1 and CRABP II were both expressed at very low levels in untreated normal human skin, and in RA-treated skin the kinetics and time course of RIS-1 and CRABP II mRNA induction were similar. Relative to VH-treated skin, RA induced RIS-1 mRNA levels within 6 h, which further increased to 6.4-fold by 24 h (n = 4). Similarly, CRABP II mRNA levels increased from 2.6-fold at 6 h to 7.8-fold after 24 h. At 48 h the relative mRNA levels for both genes decreased towards the steady-state levels. Relative to SLS-treated skin, RIS-1 mRNA increased by 3.2-fold after 6 h and by 5.1-fold after 12 h (n = 3). Also, a 2.6-fold higher CRABP II mRNA observed after 6 h increased to 6-fold after 12 h. After 24 and 48 h RA treatment the relative mRNA levels for both genes decreased towards the steady-state levels. RA-induced skin erythema was not obvious until 24 to 48 h. We conclude, therefore, that induction of RIS-1 and CRABP II mRNA levels by topical RA in human skin are early, coordinated molecular events which precede the clinical cutaneous erythematous response to RA.

Erythema annulare centrifugum with autoimmune hepatitis.

Erythema annulare centrifugum (EAC) is a rare disease entity characterized by dense perivascular lymphocytic infiltrates in dermis. It has been associated with a few conditions, though its etiology is largely unknown. To our knowledge there has been no reported association with autoimmune hepatitis described earlier. This child also was positive for hepatitis C virus antibodies, though HCV RNA was negative. We should keep in mind the false positivity of hepatitis C antibodies before deciding on its therapy.

Diagnostic value of PCR for detection of Borrelia burgdorferi DNA in clinical specimens from patients with erythema migrans and Lyme neuroborreliosis.

BACKGROUND: The aim of the study is to evaluate the diagnostic sensitivity of a 16S ribosomal RNA-based PCR on clinical specimens from patients with erythema migrans (EM) and neuroborreliosis and to compare the sensitivities with those obtained by in vitro culture and serological testing. A semiquantitative detection system, representing the input amount of specific DNA and thus the density of spirochetes in clinical specimens, indicated the preferred clinical sample to obtain for PCR testing. METHODS AND RESULTS: Skin biopsy and urine samples from 31 patients with EM and cerebrospinal fluid (CSF) and urine samples from 30 patients with neuroborreliosis were investigated. Borrelia burgdorferi DNA was detected in 71% of the skin biopsy specimens and 13% of the urine samples from patients with EM. Forty-one percent of the patients with EM were found to have B burgdorferi-specific antibodies in serum, and B burgdorferi was cultured in 29% of the EM specimens. For patients with neuroborreliosis, the diagnostic sensitivities in CSF and urine samples were 17% and 7%, respectively. Specific intrathecal antibody production was found in 90% of the patients, and 87% showed elevated B burgdorferi antibodies in serum. In general, PCR of skin biopsy samples yielded very high amounts of amplicons versus low amounts for CSF and urine samples. CONCLUSIONS: PCR of skin biopsy specimens is currently the most sensitive and specific test for the diagnosis of patients with EM, superior to culture and serological testing. For B burgdorferi-specific CSF disgnosis in patients with neuroborreliosis, the measurement of specific intrathecal antibody synthesis is superior to PCR. However, in patients with a short duration of disease (<14 days), PCR may be a useful diagnostic supplement. PCR of urine samples cannot be recommended at the present time for routine diagnosis of patients with EM or neuroborreliosis.

[The question of surgical therapy for necrolytic migratory erythema, a cutaneous disease].

Necrolytic migratory erythema (NME) is a rare paraneoplastic dermatologic condition. Its underlying cause is usually a pancreatic islet cell tumour with marked glucagon secretion. The glucagonoma syndrome is characterised by pancreatic neuroendocrine neoplasm, NME, and diabetes mellitus. We present a case of glucagonoma syndrome in a 58-year-old woman with a history of recurrent cutaneous manifestations who was referred for surgical resection of a pancreatic neoplasm after the NME was finally diagnosed. We discuss diagnostic methods, differential diagnosis, and therapeutic management of this disease.

[Comparison of the minimal erythema dose for narrowband UV-B and broad spectrum UV-B using a new UV hand-held device].

BACKGROUND: Phototherapy requires an individually adapted therapeutic regime that is based upon the minimal erythema dose for each patient. Whereas this is well established for UV-B broadband, so far no standardized equipment existed that allowed for determination of the MED for UV-B 311 nm narrowband irradiation. Thus, the starting dose for UV-B 311 nm is usually adjusted to the clinical skin type or the MED for broad-spectrum UV-B irradiation. PATIENTS AND METHODS: We determined the MED for UV-B 311 nm in a cohort of 110 healthy test persons with a newly constructed hand-held UV-light source and compared it to UV-B broadband MED. RESULTS: For UV-B broadband, the MEDs ranged from 46.2 to 210.9 mJ/cm(2) with an average value of 108.45 mJ/cm(2). For the MED of narrowband UV-B 311 nm, the values ranged from 300.9 to 1.386.0 mJ/cm(2) with an average value of 838.88 mJ/cm(2). Concerning the factor of the MED UV-B broad-spectrum related to MED UV-B 311 nm narrowband, values from 4.01 to 13.68 with a average value of 7.91 resulted. No significant differences could be detected for the MED of UV-B broad-spectrum and narrowband in correlation to age, sex or clinical skin type. CONCLUSION: Our data emphasize the presence of extensive inter-individual differences in the MED of both UV-B-spectra and point to the necessity to test patients before the first irradiation.

[Erythema induratum Bazin. "Tuberculid" or tuberculosis?].

A 66-year-old woman presented with erythematous nodules on both legs and told of a history of lymph node tuberculosis that had been treated with surgery and tuberculostatic therapy years before. A biopsy taken from a nodule showed nodular vasculitis. PCR for Mycobacterium tuberculosis-specific DNA on the paraffin-embedded tissue was positive. Based on the experience with our patient, positive PCR results for Mycobacterium tuberculosis-specific DNA in lesions of nodular vasculitis are discussed critically. The historical background of "tuberculids", such as erythema induratum Bazin, is elucidated.

[Erythema elevatum diutinum. A rare dermatosis with a broad spectrum of associated illnesses].

Erythema elevatum diutinum (EED) is a rare disease presenting with persistent red to yellow-brown papules or plaques which are mainly localized symmetrically on the extensor aspects of the hands and fingers, the elbows and the knees. The histology shows a leucocytoclastic vasculitis in early lesions and fibrosis of the dermis later on. Dapsone is the treatment of choice. Today, EED is usually assigned to the neutrophilic dermatoses in which an association with hematological disturbances is well documented. We report on a patient with EED and glioma WHO grade IV, a coincidence unreported hitherto. Additionally, we review the literature on diseases associated with EED.

[Atypical erythema induratum Bazin with tuberculous osteomyelitis].

Diagnosis of all types of cutaneous tuberculosis is challenging because the clinical picture of these diseases is highly variable. We describe the case of a 79-year old woman with an atypical presentation of Erythema induratum Bazin (EIB) on the chest and left arm in association with a tuberculous osteomyelitis of the left olecranon. Surprisingly, M. tuberculosis grew also from biopsies of the EIB-lesions. This contradicts the conventional view that considers EIB (a tuberculid) to be caused by a hypersensitivity reaction to mycobacteria. The presented case supports the hypothesis that EIB may also be caused by hematogenous or lymphatic spread of viable M. tuberculosis.

Erythemas caused by electrodes while monitoring neuromuscular blockade: three cases.

Skin erythemas formed in three patients during surgery at the sites where negative electrodes had been attached to stimulate the ulnar nerve for a neuromuscular transmission monitor (Relaxograph). The patients were all women, aged 52, 62, and 74 years, and general anesthesia lasted 8 h 20 min, 4 h 50 min, and 8 h 45 min, respectively. The electrodes used were disposable ECG electrodes in the first two patients and one designed for a neuromuscular monitor in the third; all were carbon-coated and then covered with gel. However, when the electrodes were detached from the lesion, they all showed loss or damage of the carbon coating under the gel. We recommend balancing the merit of monitoring with the risk of complications, even when applying an apparently safe, noninvasive monitor.

Erythema nodosum: the underlying conditions.

Erythema nodosum (EN) is a cutaneous reaction consisting of inflammatory, tender nodular lesions and is associated with a wide variety of disease processes. The aim of our study was to investigate the frequency of different aetiologies of EN. One hundred and thirty-two EN patients were investigated in a prospective study during the period 1984-1990. The evaluation of all patients began with a medical and family history and completed with a thorough physical examination and detailed laboratory and immunological work-up. In addition, various diagnostic procedures were performed where and when indicated. One hundred and ten patients (83%) were women. Their mean age was 41.0+/-14.0 years, range 18-79 years. In 35% the cause of EN was not found. Sarcoidosis was revealed in 28% of the patients, infections in 17.3% and tuberculosis in 1.5%. Other aetiologic factors were Adamantiadis-Behçet's syndrome (3.8%), pregnancy (6%), oral contraceptives (3.8%) and other drugs (3.8%). The aetiology of EN was not found in 35% of the patients. Sarcoidosis and infections were frequent causes of EN, whereas autoimmune rheumatic diseases rarely cause EN.

Necrolytic migratory erythema: case report and clinical review.

BACKGROUND: Necrolytic Migratory Erythema (NME) is a rarely encountered dermatologic condition. It is the characteristic feature of a paraneoplastic syndrome associated with neuroendocrine pancreatic tumors. A case of NME initially diagnosed and treated as psoriasis is reviewed. A review of the current literature regarding NME is also included. OBJECTIVE: The purpose of this report is to familiarize dermatologists with a rare and potentially fatal disorder. Early recognition of NME can lead to possible cure, while delayed identification of the disease is associated with metastatic disease and a poor prognosis for the patient. CONCLUSION: When evaluating the patient who presents with a dermatitis and weight loss, it is important to exercise great caution. The differential diagnosis should be re-evaluated in a disease that is not responsive to first-line therapy before further treatment is considered.

Varicella zoster virus infection associated with erythema multiforme in children.

BACKGROUND: Erythema multiforme (EM) is a vesiculobullous disorder with variable manifestations which predominantly affects the skin. It is regarded as a hypersensitivity disorder which is triggered by multiple factors such as infection, drugs and food. Varicella zoster virus (VZV) has rarely been reported as an etiological agent, despite its high incidence as a pathogen in childhood. PATIENTS: We describe two children in whom EM preceded VZV infection. In the first, a 5-year-old boy, EM was followed 3 days later by a classical disseminated varicella eruption. The diagnosis was reached by clinical, epidemiological and serological means. The second patient was a 13-year-old boy with EM which was followed 2 weeks later by Ramsay-Hunt syndrome. The diagnosis was confirmed by skin biopsy, positive serology and viral culture. CONCLUSION: The association of EM and VZV infection is probably more common than reported. In clinical cases of EM, VZV should be included in the list of possible causative agents.

Solitary and multiple erythema migrans in children: comparison of demographic, clinical and laboratory findings.

BACKGROUND: Data on European children with erythema migrans (EM) are limited. PATIENTS AND METHODS: 553 patients, 333 with solitary and 220 with multiple EM, diagnosed between 1996 and 2000, were included in the prospective study. Demographic, clinical and laboratory data including borrelial serum immunofluorescence assay antibody titers and Borrelia burgdorferi sensu lato blood culture results were obtained; findings in solitary and multiple EM were compared. RESULTS: Comparison revealed that children with multiple EM were younger (4.5 vs 6.5 years; p = 0.0000), less often reported a tick bite at the site of later skin lesion (25% vs 46%; p = 0.0000), had a longer incubation period (22 vs 13 days; p = 0.0028), more frequently presented with a ringlike lesion (99% vs 86%; p = 0.0000), less often reported associated local (15% vs 41%; p = 0.0000) but not systemic symptoms (28% vs 26%, p = 0.6913), more frequently had abnormal findings on physical examination (35% vs 26%; p = 0.0264), and a higher frequency of laboratory abnormalities including the presence of borrelial serum antibodies as well as B. burgdorferi sensu lato isolated from blood (12% vs 6%; p = 0.0267); younger age and male sex were identified as risk factors for the isolation of Borrelia. 40/44 isolates were Borrelia afzelii. CONCLUSION: Analysis of a large group of European children with solitary and multiple EM revealed several demographic, clinical and laboratory differences between the two groups.

Comparison of erythema migrans caused by Borrelia afzelii and Borrelia garinii.

BACKGROUND: We compared epidemiological and clinical characteristics of patients with erythema migrans (EM) caused by Borrelia afzelii and Borrelia garinii. PATIENTS AND METHODS: 200 consecutive adult patients with B. afzelii isolated from the skin lesion and 53 consecutive adult patients with EM caused by B. garinii qualified for the present study. RESULTS: Comparison of the two groups revealed several distinctions. Patients with EM caused by B. garinii were older, had their skin lesions more often located on the trunk but less often on extremities, had shorter incubation and faster evolution of EM, more often reported associated local and certain systemic symptoms, had abnormal liver function test results more often and were more frequently seropositive. CONCLUSION: Early localized Lyme borreliosis caused by B. afzelii and B. garinii has distinct epidemiological and clinical characteristics. Clinical features of EM depend upon the genospecies of Borrelia burgdorferi sensu lato causing the illness.

Neurologic abnormalities in Lyme disease without erythema chronicum migrans.

The clinical features in eight patients with neurologic abnormalities typical of Lyme disease and elevated titers of antibody to the spirochete, Borrelia burgdorferi, its causative agent, are described. None of the patients had the diagnostic skin lesion, erythema chronicum migrans. Lyme arthritis, the other clinical marker for the disease, developed subsequently in only three. The neurologic abnormalities included aseptic meningitis, encephalitis, cranial neuritis, motor and sensory radiculitis, and myelitis in various combinations. The occurrence of severe encephalitis resulting in dementia in two of these patients and irreversible myelopathy in one enlarges the known spectrum of neurologic abnormalities due to infection with B. burgdorferi. Lyme disease can present with neurologic abnormalities without diagnostic extraneural features, can be suspected on clinical and epidemiologic grounds, and can be diagnosed serologically.

Failure to isolate Borrelia burgdorferi after antimicrobial therapy in culture-documented Lyme borreliosis associated with erythema migrans: report of a prospective study.

BACKGROUND: Borrelia burgdorferi, the etiologic agent of Lyme borreliosis, has occasionally been isolated from tissues or body fluids of patients after antimicrobial treatment. A prospective study of patients with Lyme borreliosis associated with erythema migrans (EM) was initiated in Westchester County, New York, to determine: (1) the clinical and laboratory parameters associated with culture positivity, and (2) the microbiologic response to treatment. METHODS: Skin biopsies were performed in patients with EM and cultured for B. burgdorferi in modified Barbour-Stoenner-Kelly medium at 33 degrees C. Subsequent biopsies for culture were performed adjacent to the original biopsy site for culture-positive patients after the completion of antimicrobial therapy. RESULTS: Initial biopsy cultures were performed for 44 patients; 6 were unevaluable due to culture contamination with other bacteria. Cultures were positive in 21 of 29 patients prior to treatment (72%), but in none of 9 patients during treatment (p < 0.001). The only other identified factor associated with successful recovery of B. burgdorferi was shorter duration of EM. When patients who had received prior antimicrobial therapy were excluded, the mean duration of the EM lesion for those with positive cultures was 5.0 +/- 5.2 days compared with 14.6 +/- 9.9 days for those with negative cultures (p < 0.01). B. burgdorferi could not be reisolated from any of 18 evaluable subsequent biopsies of skin from 13 culture-positive patients 4 to 209 days after completion of a course of antimicrobial therapy. Five patients had negative subsequent biopsy cultures on two separate occasions 3 to 5 months apart. CONCLUSIONS: After brief courses of antibiotics, B. burgdorferi appears to be rapidly eliminated from the skin at EM sites. The ability to recover B. burgdorferi from skin biopsy cultures of untreated patients with EM lesions wanes with increasing duration of EM, suggesting that this organism may also be spontaneously cleared from skin over time.

The staphylococcal scalded-skin syndrome versus erythema multiforme.

This article reports a case of scalded-skin syndrome in a young child. Characterized by a generalized exfoliative dermatitis resembling scalded skin, the disease may involve the oral mucosa and must be differentiated from Stevens-Johnson syndrome (erythema multiforme). Since the etiology is specific, the disease can be treated with antibiotics with dramatic results.
