Melanoma is the most lethal form of skin cancer and it is the second most common cancer among adolescents and young adults. The aim of this work is to determine if surgical intervals differ between four different clinics and between departments within the hospitals, and to compare these to industry standards. Surgical intervals were measured through retrospective chart review at four dermatology clinics. Of 205 melanoma cases, clinic and departmental median surgical intervals ranged 15-36.5 days and 26-48 days, respectively. There was significant association between clinic and time between biopsy and pathology report, time between pathology report and excision, and total surgical interval (P<0.0001, P=0.03, and P<0.0001 respectively). There was significant association between department and time between pathology report and excision, and surgical interval (P<0.0001, and P=0.003 respectively). Pair-wise comparisons detected significantly longer intervals between some clinics and departments (maximum difference 67.3%, P<0.0001). Hypothesis-based, informal guidelines recommend treatment within 4-6 weeks. In this study, median surgical intervals varied significantly between clinics and departments, but nearly all were within a 6-week frame.

Is chronic cutaneous discoid lupus protective against severe renal disease in patients with systemic lupus erythematosus?

J Drugs Dermatol 2011 Dec;10(12):1413-20

Harvard Medical School, Brigham and Women's Hospital, Boston, MA, USA.

Objective: The aim was to assess the level of systemic involvement and character of renal disease in patients with chronic cutaneous lupus erythematosus of the discoid lupus variety (hereafter referred to as 'discoid lupus') and features of systemic lupus erythematosus (SLE). Clinical confusion with other types of cutaneous lupus erythematosus complicates interpretation of some previously reported studies.

Methods: Over three years, sixteen patients met the diagnostic criteria of discoid lupus, positive anti-nuclear-antibody, and at least one extracutaneous manifestation.

Results: Most patients (14/16) were female, between 26 to 66 years old. Arthritis was the most common extracutaneous manifestation followed by Raynaud's phenomenon. The anti-nuclear-antibody was speckled in ten patients with titers ranging from 1:40 to 1:1280 IU/mL. Elevated levels of double-stranded-DNA in low titers were found in four patients, anti-Smith-antibody in four; anti-Sjogren-syndrome-A-antibody in seven, and anti-ribonucleoprotein-antibody in seven. Renal function markers were transiently high in some patients but normalized over time. Hematuria and/or proteinuria were present at some time in seven patients. The highest BUN and creatinine levels were 42 mg/dL and 1.5 mg/dL, respectively. One patient had membranous glomerulonephropathy class 5; however, discoid lupus developed well after the onset of renal disease during a time when renal function had returned to normal.

Conclusion: Our observational data supports previous reports suggesting that patients with active discoid lupus rarely have progressive renal insufficiency. The mechanism for the development of discoid lupus may involve an immunologic mechanism that differs from that which produces severe organ involvement, especially advanced immune-complex-mediated renal disease. Patients with discoid lupus rarely have sustained high levels of antibodies to double-stranded-DNA. Discoid lupus appears to be a marker for a more benign lupus course. This clinical observation lays the groundwork for a larger prospective, longitudinal cohort study for further validation.

Management of psoriatic arthritis from the view of the dermatologist.

Nat Rev Rheumatol 2011 Sep 13;7(10):588-98. Epub 2011 Sep 13.

Department of Dermatology, Tufts Medical Center, 800 Washington Street, Boston, MA 02111, USA.

Psoriatic arthritis (PsA) is an inflammatory seronegative spondyloarthropathy associated with psoriasis. Although the main assessment measures for PsA are borrowed from the standard criteria used to assess rheumatoid arthritis, a number of new criteria such as the PsAJAI and CPDAI are being developed specifically for PsA. Long-term consequences of untreated PsA include persistent inflammation, progressive joint damage and, in many cases, substantial functional limitations, pain and disability. Moreover, patients with PsA have an increased mortality risk and an increased risk of developing cardiovascular disease and metabolic syndrome. Both GRAPPA and the AAD have developed treatment guidelines, which are discussed here. Psoriasis commonly precedes arthritic symptoms; thus, dermatologists are ideally placed to make the initial diagnosis of PsA and treat it appropriately, affording the opportunity to slow disease progression, improve physical function and enhance quality of life. This Review explores the management of patients with PsA, with a particular emphasis on assessment tools, long-term consequences and treatment issues from the viewpoint of the dermatologist.

Epiglottic abscess in an HIV-positive patient.

AIDS Patient Care STDS 2009 Jul;23(7):495-7

St. Luke's Roosevelt Hospital Center, New York, New York 10019, USA.

Coalescence of infection of the epiglottis, or epiglottic abscess, is a rare manifestation of epiglottitis. We report the case of a 49-year-old Hispanic man with HIV (CD4 count 243 [16.2%]), HIV viral load 175,689 copies per milliliter, antiretroviral-naive) contracted from his wife who presented to the emergency department with a 3-week history of sore throat, odynophagia, left temporal headache, left neck pain, and occasional blood-streaked sputum. This case represents the first reported case of epiglottic abscess in an HIV-positive individual. Epiglottic abscess formation is associated with potentially rapid airway compromise and carries a high mortality rate. The diagnosis of epiglottic abscess is often difficult. In HIV-infected individuals, a variety of infectious and oncologic sources of respiratory compromise should be considered in addition to epiglottic abscesses. Prompt diagnosis and treatment of this condition is crucial for ensuring optimal outcomes in this rare but often lethal infection.
