Harold O Perry: Influence Statistics

Herpes zoster has been associated with immune suppression, as has an increased risk of cancer. To determine whether patients with herpes zoster are at increased risk for subsequent cancer, we followed 590 residents of Rochester, Minnesota, for 9389 person-years after the diagnosis of herpes zoster. Subsequent relative cancer risks, overall and by specific site, were determined for the entire cohort and selected subgroups. In addition, relative risks of cancer during various intervals ...

Coal tar ointments have been used for many years in the treatment of chronic eczematoid dermatitis. The possible carcinogenic effect of coal tar ointment and ultraviolet light (Goeckerman regimen), considered individually or in combination, has been of concern to physicians. A 25-year follow-up study was completed on 426 patients with atopic dermatitis and neurodermatitis who were hospitalized and treated with coal tar ointments and ultraviolet light at the Mayo Clinic from 1950 through ...

This is a report of seven patients with cutaneous sinus tracts of dental origin who were seen in the past 10 years at the Mayo Clinic. Cutaneous sinus tracts of dental origin most commonly present on the chin or the mandibular region as nodulocystic lesions with suppuration. The lesion may be confused with pyogenic granuloma, foreign body reaction, deep fungal infection, squamous cell carcinoma, or osteomyelitis. However, if the lesion is suspected of being of dental origin, the ...

A population-based epidemiologic study of pityriasis rosea was developed for Rochester, MN, for a recent 10-year period. Nine hundred thirty-nine patients with pityriasis rosea (340 male patients and 599 female patients) who resided within Rochester city limits at the time the diagnosis was made were included. The average annual incidence rate of this disease was 172.2 per 100,000 person-years (158.9 per 100,000, adjusted to the 1970 U.S. white population). Female patients predominated ...

Pyoderma gangrenosum, traditionally associated with chronic ulcerative colitis, is recognized by the rapidity of development of a liquefying and necrotizing ulceration. Three patients are described, each of whom developed an atypical, superficial bullous form of pyoderma gangrenosum. Study eventuated in the discovery of leukemia in each patient. Biopsy specimens of the skin lesions failed to show the histologic findings of lymphoma. To a degree, the course of the skin lesions paralleled ...

We are reporting the third case of the Olmsted syndrome, an entity that has received little attention in the medical literature. The syndrome consists of congenital diffuse, sharply marginated keratoderma of the palms and soles, onychodystrophy , constrictions of digits, and periorificial keratoses. Our patient, in addition, had congenital universal alopecia, absence of a premolar tooth, leukokeratosis of oral tissue, and hyperlaxity of the joints. The differential diagnosis includes ...

Treatment of cicatricial pemphigoid is a problem because patients afflicted are elderly, the disease is chronic, systemic agents required for control are potentially toxic (particularly to older patients), and the disease is often in an advanced stage when the diagnosis is established and requires aggressive therapy for control. We selected dapsone as an alternative anti-inflammatory agent because it has provided control in a subset of patients with bullous pemphigoid, five of six who ...

The carpal tunnel syndrome, although a well-defined clinical entity, has been appreciated only recently as a manifestation of systemic diseases. Its special architecture may reflect diseases in which acral edema is a factor. Carpal tunnel syndrome associated with such conditions as dermatomyositis and scleroderma may be relieved symptomatically by the systemic use of corticosteroids. Observations on five cases are reported. Carpal tunnel syndrome coexisted with dermatomyositis in four ...

Two patients each with a two-year history of chronic ulcerative colitis developed, over a 24- to 48-hour period, painful pustules involving the skin and oral mucosa. The pustular eruption was associated with a severe exacerbation of the colitis. Culture of the lesions and of the blood failed to reveal an infectious cause for the eruption. Histologic study of a pustule in case 2 revealed suppurative folliculitis. The lesions subsided rapidly in case 1 when intravenous hydrocortisone and ...

Immunopathologic investigations were conducted on the sera and oral mucosal tissue specimens of 23 patients with cicatricial pemphigoid. A linear, continuous basement membrane zone pattern was noted in 83% of oral mucosal biopsy specimens studied. This pattern is indistinguishable from the pattern noted in immunofluorescence studies of bullous pemphigoid, herpes gestationis, and some cases of desquamative gingivitis. Complement studies provided data supportive of classical pathway ...

The records of eight patients with pyoderma gangrenosum and monoclonal gammopathy showed that all patients except one had an IgA paraproteinemia. To date, seven patients have had a benign course and multiple myeloma has developed in one. In seven patients, the onset of the pyoderma gangrenosum preceded the detection of the monoclonal gammopathy. The monoclonal gammopathy did not seem to influence the morphologic findings, course, or therapy of the pyoderma gangrenosum. In the one patient ...

A patient with dermatomyositis developed malignant transformation of the benign interfascial heterotopic bone. This patient had classic childhood dermatomyositis at the age of 3 years, and the disease was arrested after a one-year course of corticosteroid therapy. Extensive subcutaneous calcinosis cutis and deep interfascial calcinosis were the residua of the disease. Twenty-eight years later, the patient developed a high-grade osteosarcoma within the benign intermuscular heterotopic ...

For many years, crude coal tar has been used for the treatment of psoriasis. The possible carcinogenic effect of crude coal tar and ultraviolet (UV) radiation (Goeckerman regimen), considered individually or in combination, has been of some concern to physicians. A 25-year follow-up study was completed on 280 patients with psoriasis who were hospitalized and treated with crude coal tar and UV radiation at the Mayo Clinic, Rochester, Minn, during the years 1950 through 1954. The results ...
