Leg ulcerations secondary to chronic venous insufficiency have been termed 'stasis ulcers.' This is based on an original idea proposed by Homans in 1917. However, since then data has been generated suggesting in fact 'stasis' does not occur. In this paper, we review the information that has accumulated, refuting the concept of stasis. We suggest that the term 'stasis ulcer' is a misnomer, and should be abandoned.
Psoriasis is a chronic, recurrent, and often disfiguring skin disease that may significantly affect patients' quality of life. Treatment of psoriasis, including hospitalization, has been shown to improve quality of life. A pilot study of 15 consecutive inpatients and 7 consecutive outpatients with psoriasis were asked to complete the Dermatology Life Quality Index (DLQI) before treatment and 3 months later. Hospitalized patients also completed the DLQI 1 week after discharge. Statistical analysis using t tests compared pretreatment and posttreatment DLQI scores as well as improvement of inpatients versus outpatients. Baseline DLQI scores for hospitalized patients were significantly higher (greater impairment of life quality) compared with oupatients' quality of life. After discharge, hospitalized patients' quality of life had significantly improved at 1 week and remained improved at 3 months.

Dermatomyositis is an uncommon inflammatory myopathy accompanied by characteristic cutaneous findings. Adult-onset dermatomyositis is often associated with internal malignancy. We report a case of dermatomyositis associated with an aggressive and fatal case of transitional cell carcinoma of the bladder.
Pyoderma gangrenosum (PG) is a painful, often rapidly progressive, ulcerating skin disorder frequently associated with systemic diseases. We report the case of a patient with PG and an anemia. A bone marrow biopsy showed changes consistent with one of the myelodysplastic syndromes, refractory anemia with ringed sideroblasts. Patients with PG and anemia should have bone marrow biopsy if no cause of anemia is readily apparent.

Psoriasis is a common dermatosis, affecting from 1 to 3 percent of the population. Until recently, the mainstays of topical therapy have been corticosteroids, tars, anthralins and keratolytics. Recently, however, vitamin D analogs, a new anthralin preparation and topical retinoids have expanded physicians' therapeutic armamentarium. These new topical therapies offer increased hope and convenience to the large patient population with psoriasis.
OBJECTIVE: To compare the behavior of a tissue-engineered living skin equivalent (LSE) with an autograft in acute donor site wounds. DESIGN: Paired-comparison, randomized control trial. SETTING: A university dermatology service. PATIENTS: Three donor sites were created on the anterior thigh of each of 20 patients requiring split-thickness skin grafts. INTERVENTION: For each patient, the donor sites were randomly assigned to be treated with meshed LSE, meshed autograft, or a polyurethane film (PUF) occlusive dressing. Blood and biopsy samples were taken for immunologic and histological studies. MAIN OUTCOME MEASURES: Toxic effects or clinically apparent rejection, humoral and cellular immune responses, clinical take, healing time, pain, and 1-month histological appearance. RESULTS: There was no toxic effect or clinically apparent rejection of LSE. Results of humoral and cellular studies were unchanged from baseline. The average time to healing for LSE with clinical take was 7.3 days (SD, +/- 0.8 days); for autograft, 7.6 days (SD, +/- 1.1 days); and for PUF, 9.5 days (SD, +/- 1.8 days). The difference between LSE or autograft and PUF was statistically significant at the .001 level. Pain was experienced by 1 patient, no patients, and 10 patients at the LSE, autograft, and PUF sites, respectively. Histologically, LSE had the thickest epidermis (P = .02), PUF had the greatest degree of fibrosis (P = .02), and autograft had the least degree of increased inflammation (P = .004) and vascularity (P = .01). CONCLUSIONS: In acute donor site wounds, LSE appeared to clinically take and to be a safe and usable form of tissue therapy.
BACKGROUND: Changes in health care delivery financing such as the adoption of the diagnosis-related groups (DRG) in 1983 has affected inpatient services of dermatology programs across the United States. OBJECTIVE: The purpose of this study was to define the present status of inpatient dermatology at academic medical centers compared with 1982. METHODS: Questionnaires inquiring about the state of inpatient service were sent to the chairpersons of each dermatology residency program in the United States. RESULTS: Of the 71 programs responding, 79% reported a reduction in inpatient activity. Nearly half of the dermatology programs with dedicated dermatology beds in 1982 reported not continuing to have these in 1997 (41 to 24). The average number of patients admitted for skin disease decreased from 1 19 in 1982 to 36.5 in 1997, and the average daily census decreased from 8.9 to 2.2. CONCLUSION: There has been a decline in the number of patients hospitalized by academic dermatology departments and a shift of some patients hospitalized to beds where the attending is other than a dermatologist.
BACKGROUND: Severe skin disease uncommonly requires hospitalization. The number of patients hospitalized for skin disease annually in the United States has never been reported. OBJECTIVE: We evaluated the number of patients admitted for skin disorders. METHOD: Using data from 2 national databases, the Healthcare Cost and Utilization Project-3 Nationwide Inpatient Sample (HCUP-3 NIS) 1992-1994 and Medicare Provider Analysis and Review (MEDPAR) 1990-1996 file, we evaluated the total discharges, total charges, and reimbursement of the dermatology-specific (272, 273, 283, and 284) and -related (263, 264, 265, 266, 271, 277, 278, and 279) diagnosis-related groups (DRGs). RESULTS: In 1994, the HCUP-3 NIS data showed that a total of 468,014 discharges were classified under Dermatology DRGs, whereas in 1996 MEDPAR data gave a figure of 183,310 discharges with a total Medicare reimbursement of $892 million. In both data sets, dermatology-specific DRGs show a decrease over time, although dermatology-related DRGs generally showed an opposite increasing pattern. The top 10 states reimbursed by Medicare in 1996 for the discharges grouped under the DRGs mentioned above were New York, California, Pennsylvania, Florida, Texas, Ohio, Illinois, Michigan, New Jersey, and Massachusetts. CONCLUSION: Many patients are admitted annually for skin disease. The minority are admitted by dermatologists.

The use of the carbon dioxide laser for skin resurfacing was initially described in 1989. 1 Since that time, several reports have shown it to be highly effective in the treatment of photodamaged skin and acne scarring. 2,3,4,5 Advances in laser technology have simplified the procedure and minimized adverse sequelae. Laser skin resurfacing has become a very popular technique, and recently several patient series have been published on the use of different resurfacing lasers to treat photodamaged skin. 3,4 However, very little has been written about its complications. Adequate patient selection, sound medical judgement, proper training with experience and knowledge of skin physiology and wound care are important factors for successful outcomes. Interested physicians across a broad range of subspecialties have expressed concern about the rate of adverse outcomes and management of complications. We report seven representative cases of complications referred to our dermatology clinics from outside physicians, in the hope of educating clinicians regarding the usual and unusual side effects of this procedure.
BACKGROUND: Little is known about the relationship between academic medical centers (AMCs) and community physicians (CPs). We examined this relationship for an individual specialty-dermatology. METHODS: South Florida dermatologists were queried regarding their practice and referral patterns, as well as the effect of managed care on these patterns. RESULTS: On average, the respondents see 7,342 patients annually. Ninety-eight percent refer one or more patients for aid in therapy (39%) and diagnosis (27%). Most were satisfied with the amount (63%) and quality (77%) of the service provided. Overall, only 0.2% of patients are referred. Sixty percent reported that managed care caused alterations in referral patterns. CONCLUSIONS: We found that, although community dermatologists diagnose and treat the vast majority of patients with skin disease seen by dermatologists, they also use and are satisfied with the AMC's services. Changes in referral patterns have occurred but have not negatively affected the relationship between the AMC and the CP.
Leukocytoclastic vasculitis, presenting with palpable purpura, is a relatively common problem encountered by both primary care practitioners and dermatologists. A variety of potential etiologies exists and includes autoimmune, neoplastic, and infectious causes. We report a case of leukocytoclastic vasculitis that led to the diagnosis of acute hepatitis B, perhaps acquired through colonoscopy.
BACKGROUND: Skin cancer incidence is increasing, but whether primary care providers routinely screen for skin cancer is not known. OBJECTIVE: We assessed whether primary care practitioners are performing skin cancer screening within the context of primary care and whether barriers exist that might act as impediments to the implementation of this practice. METHODS: A total of 465 primary care providers belonging to their respective county medical societies in either New Haven County, Connecticut, or Miami-Dade County, Florida were randomly selected and surveyed by mailed questionnaire regarding their skin cancer screening practices. RESULTS: Only 31% of responding physicians reported performing skin cancer screening on all of their adult patients. Of those not performing skin cancer screening on all adult patients, only 31% report performing screening on high-risk patients. Almost half of physicians reported that they do not perform skin cancer screening. We found that physicians' lack of confidence in identifying suspect lesions was a common barrier. Fear of patient embarrassment, inadequate lighting, or lack of studies demonstrating mortality benefits were not frequent deterrents. Furthermore, there was no statistical difference in screening rates between the more northern latitude and the more southern latitude. CONCLUSION: Skin cancer screening is not being performed within the context of primary care visits. Barriers exist that may impede skin cancer screening.
