The clinical spectrum of early lyme borreliosis in patients with culture-confirmed erythema migrans

BACKGROUND The diagnosis of erythema migrans (EM), the characteristic rash of early Lyme borreliosis, is based primarily on its clinical appearance since it often occurs prior to the development of a specific antibody response. Other skin disorders, however, may be confused with EM. METHODS Between June 1991 and September 1993, a prospective study was conducted at the Lyme Disease Diagnostic Center of the Westchester County Medical Center to isolate Borrelia burgdorferi systematically from patients with Em, and to characterize the clinical manifestations of patients with culture-documented infection. Skin biopsies and/or needle aspirates of the advancing margin of primary lesions, and blood specimens from adult patients were cultured for B burgdorferi in modified Barbour-Stoenner-Kelly medium at 33 degrees C. RESULTS B burgdorferi was recovered from 79 patients (49 [62%] males) ranging in age from 16 to 76 years old (mean, 43 +/- 14 years old). Maximum EM diameter (mean, 16 +/- 10 cm; range, 6-73 cm) was a function of EM duration (mean 6.7 +/- 6.4 days; range, 1-39 days) (correlation coefficient = 0.7; P < 0.001). Twenty (25%) patients had noted a tick bite at the site of the primary lesion a mean of 10 days (range, 1-27 days) before onset. Multiple EM lesions (range, 2-70) were present in 14 (18%) patients. Systemic symptoms were present at the time of culture in 54 patients (68%) including fatigue (54%), arthralgia (44%), myalgia (44%), headache, (42%), fever and/or chills (39%), stiff neck (35%), and anorexia (26%). Thirty-three patients (42%) had at least one objective finding on physical examination in addition to EM, including 18 (23%) with localized lymphadenopathy, 13 (16%) with fever (t > or = 37.8 degrees C), seven (9%) with tender neck flexion, six (8%) with joint tenderness, and 1 each with joint swelling, nuchal rigidity, and facial nerve palsy. No patient had new electrocardiogram evidence of atrioventricular block. Liver function assays were abnormally elevated in 37% of patients. Thirty-four percent of patients were seropositive by enzyme-linked immunosorbent assay at presentation. Most others rapidly seroconverted so that 69 of 78 evaluable patients (88%) were seropositive at some point during the first month after diagnosis. CONCLUSIONS We describe the largest group of culture-positive patients with EM from the United States to date. Although systemic symptoms were present in most patients, objective evidence of advanced disease was uncommon. Our patients with culture-confirmed EM were less sick than those described in the days before culture confirmation was possible. The ability to isolate B burgdorferi from lesional skin of large numbers of patients with EM should make culture-positive patients the standard by which to define manifestations of early Lyme borreliosis associated with this rash. Microbiologic documentation of Lyme borreliosis will help delineate the manifestations of this illness, and should form the framework for research directed at pathophysiology, diagnosis, treatment, and prevention.

Pemphigus vulgaris and pregnancy: risk factors and recommendations.

Pemphigus vulgaris during pregnancy is exceedingly rare; only 15 cases with immunopathologic confirmation have been reported. In the four cases associated with fetal mortality the mothers disease was active and required high doses of corticosteroids and adjuvant therapy with azathioprine or dapsone for control. A pregnant woman with limited disease is described. At the time of delivery her pemphigus vulgaris antibody titer was 1:640. A full-term, healthy male infant was completely free of skin lesions after a spontaneous vaginal delivery.

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.

Pemphigus vulgaris of the esophagus in women

A case of pemphigus vulgaris with esophageal involvement is discussed and 10 other reported cases are reviewed. Esophageal involvement is a rare but serious occurrence. It is most readily diagnosed by endoscopy when dysphagia or odynophagia in a patient with pemphigus vulgaris or with a history of pemphigus vulgaris does not respond to appropriate adjustment of corticosteroid or other therapy. All patients with esophageal pemphigus vulgaris were middle-aged women. None had skin lesions at the time esophageal disease was diagnosed, and five patients appeared to be in complete remission, with neither skin nor oral lesions, when esophageal involvement was discovered.

Gigantic malignant melanoma in a thermal burn scar

Carcinoma developing in burn scars is overwhelmingly of the squamous cell type; in fact, almost 2% of all squamous cell carcinomas develop in old burn scars. We report a case of malignant melanoma that developed in a burn scar and review eight other reported cases of malignant melanoma that developed similarly. We also compare the group having malignant melanomas in burn scars with those having the more common type of squamous cell carcinoma in burn scars.

Giant cell lichenoid dermatitis: A possible manifestation of sarcoidosis

Giant cell lichenoid dermatitis is a recently described dermatosis thought to be an unusual lichenoid drug eruption. It is characterized by a generalized, pruritic, papulosquamous eruption sparing palms, soles, face and mucous membranes. Histopathologic findings include areas of epidermal hyperplasia and atrophy with focal vacuolar alteration of the basal layer, exocytosis and cytoid body formation. The dermis contains a band‐like, mononuclear cell infiltrate at the dermoepidermal junction with admixed cosinophils, plasma cells and large multinucleate cells. The histologic differential diagnosis includes infectious processes, sarcoidosis, lichen nitidus, lupus erythematosus and lichen planus. We report 3 patients with giant cell lichenoid dermatitis, one of whom was subsequently diagnosed as having sarcoidosis. Because giant cell lichenoid dermatitis may resemble sarcoidosis both clinically and histologically, and because cutaneous sarcoid is often associated with systemic involvement, the diagnosis of sarcoid should be strongly considered in patients with giant cell lichenoid dermatitis.

Antinuclear antibodies during psoralens plus ultraviolet A (PUVA) therapy—are they worthwhile?

From 1979 to 1985, 497 patients with psoriasis were started on psoralens plus ultraviolet A (PUVA) therapy at Northwestern University. Two hundred sixty-nine of these received therapy for greater than 3 months and had at least two antinuclear antibody (ANA) determinations. We have found that the difference between the number of significantly positive ANAs pre-PUVA therapy (4 of 269) compared to post-PUVA therapy (16 of 269) was not statistically significant. Furthermore, of the patients who did develop a significantly positive ANA, not one was found to have any symptoms, signs, or laboratory evidence of systemic lupus erythematosus. We therefore suggest obtaining ANAs prior to initiating PUVA therapy and obtaining follow-up ANAs only if the initial ANA is significantly positive. Patients with pre-PUVA--positive ANAs can be started on PUVA therapy if there is no evidence of lupus erythematosus.
