Association of Postoperative Antibiotics With Surgical Site Infection in Mohs Micrographic Surgery.

BACKGROUND: Surgical site infection (SSI) is the most frequent complication of Mohs micrographic surgery. Previous studies have identified risk factors for SSI, but it is not known whether antibiotic prophylaxis mitigates this risk. OBJECTIVE: To measure the association between antibiotic prophylaxis and SSI in a convenience sample of Mohs cases and to report on the utility of propensity scoring to control for confounding by indication in registry data. METHODS: Data were drawn from a pilot quality improvement registry of 816 Mohs cases. The relationship between antibiotic prophylaxis and SSI was assessed with logistic regression modeling using propensity score methods to adjust for confounding. RESULTS: One hundred fifty-one cases were prescribed antibiotic prophylaxis (18.5%). Of 467 cases with follow-up, 16 (3.4%) developed SSI. Infection rates were higher in subjects prescribed prophylaxis, but propensity adjustment reduced this effect. Adjusted odds of infection were 1.47-fold higher in subjects prescribed antibiotics and not statistically significant (95% confidence interval 0.29-7.39; p = .64). CONCLUSION: Although there was no significant difference in SSI among patients prescribed prophylactic antibiotics, statistical precision was limited by the low incidence of infection. Larger population-based prospective registry studies including propensity adjustment are needed to confirm the benefit of prophylactic antibiotics in high-risk surgical cases.

Performance Measures in Dermatologic Surgery: A Review of the Literature and Future Directions.

BACKGROUND: In recent years, health care reform initiatives have aimed to assess quality of care through the use of performance measures. Multiple specialties, including dermatology, have implemented registries to track and report health care quality. OBJECTIVE: The authors review the history and rationale for assessing quality in dermatologic surgery. The authors also discuss the different types of performance measures and the current efforts to develop clinically relevant dermatologic surgery-specific measures. MATERIALS AND METHODS: An extensive literature review was conducted using OVID, MEDLINE, PubMed, and government and health care-related websites to identify articles related to surgical performance measures. RESULTS: Few performance measures are established to assess quality in dermatologic surgery. The authors propose specific candidate measures and discuss how clinical registries can capture measures that meet federal reporting requirements. CONCLUSION: Assessment of health care quality will become increasingly important in health care reform. Physicians need to take an active role in selecting appropriate, clinically relevant performance measures that will help improve patient care while containing health care costs and meeting government-mandated reporting requirements.

Diabetic ketoacidosis associated with aripiprazole.

Metabolic adverse effects such as hyperglycemia, alterations in insulin sensitivity, and weight gain are known to be potential complications of atypical antipsychotic therapy. In certain cases, hyperglycemia may be so profound that diabetic ketoacidosis (DKA) or hyperosmolar coma may result. Aripiprazole, approved by the United States Food and Drug Administration in 2002, appears to have fewer metabolic adverse effects than other atypical antipsychotics. We describe a 44-year-old man with no personal or family history of diabetes mellitus who was prescribed aripiprazole for schizoaffective disorder. Two weeks after starting this therapy, the patient developed DKA, which was corrected with insulin therapy and aggressive hydration. According to the Naranjo adverse drug reaction probability scale, aripiprazole was the probable trigger of his DKA. An exhaustive search for other causes of DKA was unrevealing. Administration of aripiprazole or any other atypical antipsychotic should be terminated when impaired glucose tolerance is suspected. Vigilance regarding the potential adverse effects of this class of drugs, including new agents such as aripiprazole, is crucial to preventing potentially life-threatening complications of hyperglycemia.

Adherence to acitretin and home narrowband ultraviolet B phototherapy in patients with psoriasis.

BACKGROUND: In the treatment of psoriasis, patient adherence to oral medications is poor and even worse for topical therapy. However, few data exist about adherence rates to home phototherapy, adding to concerns about the appropriateness of home phototherapy as a psoriasis treatment option. OBJECTIVE: We sought to assess adherence to both oral acitretin and home ultraviolet B phototherapy for the treatment of psoriasis. METHODS: In all, 27 patients with moderate to severe psoriasis were treated with 10 to 25 mg of acitretin daily, combined with narrowband ultraviolet B, 3 times weekly at home, for 12 weeks. Adherence to acitretin was monitored by an electronic monitoring medication bottle cap, and to phototherapy by a light-sensing data logger. RESULTS: Adherence data were collected on 22 patients for acitretin and 16 patients for adherence to ultraviolet B. Mean adherence to acitretin decreased steadily during the 12-week trial (slope -0.24), whereas mean adherence to home phototherapy remained steady at 2 to 3 d/wk. Adherence was similar between patients who reported side effects and those who did not. LIMITATIONS: Small sample size and lack of follow-up on some patients were limitations of this study. CONCLUSIONS: Adherence rates to home phototherapy were very good and higher than adherence rates for the oral medication. Side effects of treatment were well tolerated in this small group and did not affect use of the treatment. Home phototherapy with acitretin may be an appropriate option for some patients with extensive psoriasis.

Photosensitizing agents and the risk of non-melanoma skin cancer: a population-based case-control study.

Robinson et al. report a population-based case-control study to examine the association between a history of photosensitizing medication use and non-melanoma skin cancer. They report an increased risk of basal cell carcinoma with tetracycline use and of squamous cell carcinoma with diuretic use. Appropriate counseling regarding sun exposure may reduce skin cancer in patients exposed to these medications.

Development of Beau's lines in two patients receiving azathioprine.

We report two cases of patients who developed Beau's lines while taking azathioprine. In each case, the patient developed a hypersensitivity reaction to the medication. These are the first reported cases of a hypersensitivity reaction to azathioprine leading to Beau's lines.
