Topical glutaraldehyde-percutaneous penetration and skin irritation.

To investigate the safety of the topical application of glutaraldehyde to the ankle and heel of man, the in vitro penetration of glutaraldehyde in a 10% aqueous solution through isolated human thin stratum corneum (chest and abdomen), isolated human epidermis (abdominal), and human thick stratum corneum (blister tops from the sole) was determined 1 h after application. Under these conditions, glutaraldehyde did not penetrate thick stratum corneum, while 2.8%-4.4% of the applied dose penetrated the isolated epidermis, and 3.3%-13.8% of the applied dose penetrated thin stratum corneum. An 8-week irritancy test was conducted by applying a 10% aqueous solution of glutaraldehyde to the ankle and heel area of 12 volunteers. Irritation and one case of sensitization resulted from glutaraldehyde application to areas of thin stratum corneum (anterior ankle) but not from applications to thick stratum corneum (medial, posterior, and lateral heel and posterior ankle), which may be a privileged site with respect to glutaraldehyde sensitivity.

Primary cutaneous aspergillosis.

A 6-year-old boy with acute monocytic leukemia and therapy-induced leukopenia developed multiple necrotizing skin lesions where an intravenous administration unit had been secured to his arm and hand. Biopsy and cultures demonstrated Aspergillus flavus as the etiologic agent without evidence of systemic dissemination. Resolution of the infection occurred following systemic amphotericin B therapy and a granulocyte transfusion.

Mixed connective tissue disease.

A study was done that involved 46 patients with high-titer serum antibody to ribonucleoprotein (RNP). Common cutaneous manifestations included swollen hands or sclerodactyly (50 percent), cutaneous lupus erythematosus (48 percent), periungual telangiectasia (46 percent), alopecia (46 percent), dyspigmentation (28 percent), photosensitivity (28 percent) and vasculitis (22 percent). Frequent systemic characteristics included Raynaud phenomenon (93 percent), arthritis or arthralgia (91 percent), adenopathy (43 percent), vascular headaches (35 percent), serositis (35 percent), hoarseness (28 percent), myositis (26 percent), sicca syndrome (24 percent), renal disease (17 percent) and central nervous system disease (9 percent). Associated laboratory findings included antinuclear antibodies (100 percent), epidermal nuclear lgG deposition (91 percent), hypergammaglobulinemia (78 percent), esophageal dysmotility (61 percent), abnormal pulmonary function (59 percent), rheumatoid factor (57 percent), lupus erythematosus cells (37 percent), positive lupus band test (34 percent), hypocomplementemia (28 percent) and elevated anti-nDNA (21 percent). It appears that patients with high-titer anti-RNP (without appreciable amounts of "anti-Sm") have a high prevalence of Raynaud phenomenon and a low prevalence of progressive renal insufficiency and severe central nervous system disease.

Allergic hypersensitivity to neomycin. Relationship between patch test reactions and 'use' tests.

The prevalence of neomycin patch test sensitivity in the general population is approximately 1%. We describe the relationship between positive neomycin patch tests and clinical "use tests" with two antibiotic combinations (Neosporin G cream and Neosporin ointment). The neomycin use test was positive in seven of eight subjects with a strongly positive patch test, and in two of four subjects with a weakly positive patch test. A positive use test usually occurred earlier and was always more intense with the cream base. The use test reactions were usually mild even with continued application of the antigen. Use tests with commercial products may be helpful in evaluating the clinical relevance of positive patch tests.

Allergic contact hypersensitivity to nickel, neomycin, ethylenediamine, and benzocaine. Relationships between age, sex, history of exposure, and reactivity to standard patch tests and use tests in a general population.

A study population of 1,158 paid adult volunteers was obtained. Prior to patch testing, a history of previous exposure to four allergens also was obtained. Prevalence of positive reactions to patch tests was nickel, 5.8%; neomycin, 1.1%; ethylenediamine, 0.43%; and benzocaine, 0.17%. Nine percent of women reacted to nickel compared with 0.9% of men. There was a strong correlation of nickel sensitivity with a history of pierced ears, earlobe rash, and jewelry rash. Ten of 12 neomycin-positive subjects used neomycin for one week or longer on an inflammatory dermatosis, compared with six of 36 age-, race-, and sex-matched controls. By history, 85% were exposed to benzocaine, 48% to neomycin, and 15% to Mycolog (ethylenediamine). Of 127 patients referred to clinics for evaluation of contact dermatitis, 11% yielded positive tests to nickel, 6.3% to neomycin, 3.1% to ethylenediamine, and 1.6% to benzocaine. Data obtained from testing contact dermatitis patients are not applicable to the general population.

Speckled (particulate) epidermal nuclear IgG deposition in normal skin. Correlation of clinical features and laboratory findings in 46 patients with a subset of connective tissue disease characterized by antibody to extractable nuclear antigen.

Clinical and laboratory findings were correlated from 46 patients with IgG localization in epidermal nuclei in a speckled (particulate) pattern on direct immunofluorescence of normal skin. Cutaneous manifestations included lupus erythematosus (LE), swollen hands or sclerodactyly, alopecia, vasculitis, and dyspigmentation. Systemic manifestations included arthritis or arthralgia, Raynaud's phenomenon, serositis, vascular headaches, mild renal disease, myositis, and sicca syndrome. High titer (mean = 1:142, 800) serum antibody to extractable nuclear antigen (ENA) was found in 81%. Eighty-six percent had antibody to an RNase-sensitive antigenic component of ENA (ribonucleoprotein or RNP); 14% had antibody to an RNase-resistant ENA termed Sm. Deposition of IgG in a speckled pattern in epidermal nuclei is an immunopathologic marker for a subset of connective tissue disease characterized by antibody to ENA. Those with Sm specificity had systemic LE (SLE); Those with RNP specificity had Raynaud's phenomenon usually associated with overlapping features of SLE, scleroderma, and/or dermatomyositis.

Cerebrospinal fluid findings in asymptomatic patients with reactive serum fluorescent treponemal antibody absorption tests.

It is common to examine the cerebrospinal fluid in untreated or inadequately treated asymptomatic patients with a reactive serum fluorescent treponemal antibody absorption (FTA-ABS) test before initiating antibiotic therapy for syphilis. This prospective study evaluated the usefulness of such examination. Four hundred thirty-two patients over 40 years old, reporting for annual physical examination, had a serum FTA-ABS test. Thirty-seven (8.6%) patients and 2 of 4 spouses were reactive repeatedly. Of the 39 patients with reactive tests, 7 had a history of penicillin therapy for syphilis, 5 had received heavy metal therapy, and 27 had no history of syphilis. These 39 patients had a neurological examination, serum VDRL, Treponema pallidum immobilization (TPI), and repeat FTA-ABS tests by two other laboratories. The TPI test was reactive in 30 (77%). Four had nonspecific neurological signs. Routine CSF examination (cells, total protein, VDRL, glucose, IgG%) on 30 patients with a history of inadequate treatment had a low diagnostic yield. Two patients had an unexplained total protein elevation (57 and 61 mg/dl) and 1 had a mildly increased IgG% (15%). All cell counts, VDRL tests, and glucose levels were normal. Agarose electrophoresis demonstrated one or more CSF immunoglobulin bands in 10 (36%) of 28 patients, possibly representing an immunological marker of past or latent central nervous system infection.

Nasopharyngeal cardcinoma associated with long-term arsenic ingestion.

A nasopharyngeal carcinoma occurred in a 41-year-old white woman who had received Fowler's solution (potassium arsenite) almost yearly for more than 20 years for the treatment of psoriasis. Palmar and plantar keratoses were present. Because of the rarity of this malignant neoplasm in white people, a relationship with arsenic ingestion is suggested.

Glutaraldehyde (pentanedial) allergic contact dermatitis. Usage test on sole and antecubital fossa: regional variations in response.

Glutaraldehyde (pentanedial) is an effective topical therapeutic agent for patients with hyperhidrosis of the soles. A usage test was performed on the soles and antecubital fossae of six previously documented glutaraldehyde-sensitive subjects. All had negative usage test reactions to 25% glutaraldehyde on the soles. But when tested on the antecubital fossae with 2.5% glutaraldehyde, they developed a severe dermatitis within 48 hours. These data demonstrate a striking variation by which glutaraldehyde-sensitive patients tolerate or react to its use in two diverse anatomic sites.

Antinuclear antibody studies in chronic cutaneous discoid lupus erythematosus.

The prevalence of antinuclar antibodies (ANA) in chronic cutaneous discoid lupus erythematosus (DLE) is influenced by both patient selection and test sensitivity. If one excludes serum samples from patients with DLE with a history suggesting extracutaneous disease and defines the significance of the ANA test by simultaneously testing serum samples from patients with well-characterized connective tissue diseases, then only a small percentage of the patients with DLE have ANA at significant titers. These patients with DLE do have a higher pervalence of positive ANA tests at low serum dilutions when compared with controls, but only a few have positive ANA tests at titers comparable to those seen in patients with active systemic connective tissue diseases.

A cutaneous marker in the Hunter syndrome a report of four cases.

A report of four patients and review of the literature suggest that a cutaneous marker exists for the Hunter syndrome. All previously described patients with this eruption have been males with clear corneas. The distinctive lesions consist of firm ivory-white papules and nodules that may coalesce to form ridges or a reticular pattern. The papules are usually seen in symmetrical areas between the angles of the scapulas and posterior axillary lines, the pectoral regions, the nape of the neck and/or on the lateral aspects of the upper arms and thighs. These lesions are seen in both allelic forms and cannot be used to separate a benign from a rapid course.

Mixed connective tissue disease syndrome.

Fifteen patients with epidermal nuclear staining on direct immunofluorescence of normal skin and high titer serum antibody to ribonuclease-sensitive extractable nuclear antigen (ENA) had diffuse nonscarring and focal alopecia, abnormal pigmentation, swollen hands with sclerodactyly, and chronic cutaneous lupus erythematosus (LE) as the most common dermatologic features. Direct immunofluorescence of normal, unexposed skin revealed a particulate ('speckled') epidermal nuclear staining pattern in all 15 patients and subepidermal immunoglobulin deposits in 5. Ribonucleoprotein antibodies in high titer are associated with this characteristic type of epidermal nuclear staining. These findings provide easily detectable markers for a less aggressive subset of LE characterized by distinctive clinical and laboratory features consistent with mixed connective tissue disease.

Conversion of discoid lupus erythematosus to mixed connective tissue disease.

The progression from discoid lupus erythematosus (DLE) to severe systemic lupus erythematosus (SLE) is rare. Two patients with DLE for five and 10 years eventually developed systemic involvement with clinical features of mixed connective tissue disease (MCTD). Both patients had high titer serum antibody to ribonucleoprotein (RNP) and epidermal nuclear staining on direct immunofluorescence of normal skin. Neither patient had renal disease but one patient developed pulmonary involvement. This observation suggests that patients with DLE and the Raynaud phenomenon may have a connective tissue disease subset characterized by anti-RNP, the immunologic marker for MCTC.

Epidermodysplasia verruciformis.

Epidermodysplasia verruciformis (EV) is characterized by the early onset of extensive, persistent verruca plana that may undergo malignant transformation. Immunologic studies of a case of EV confirmed by electron microscopic identification of the virus disclosed no detectable abnormalities. The importance of this uncommon clinical syndrome lies in its demonstration that benign papovavirus, the etiologic agent of warts, can produce malignant neoplasms in genetically susceptible hosts.
