Managing skin toxicities related to panitumumab.

BACKGROUND: Dermatologic toxicities from targeted agents such as panitumumab can interfere with cancer treatment. OBJECTIVE: We sought to evaluate the rash assessment and management in a consecutive patient cohort who received panitumumab for colorectal cancer treatment. METHODS: This was a retrospective chart review. RESULTS: Skin toxicity, consisting of papulopustular rash, was experienced by 32 of 34 patients. The majority (85%) developed the rash by the end of the second infusion cycle. Patients presented with a mild (41%), moderate (38%), and severe (21%) rash, and progressed to an extensive rash without appropriate treatment. A grading system was used for 65% of patients to document severity. LIMITATIONS: Small sample size limited power in analysis. Rash severity had to be inferred based on rash description and management in 11 of the patients. CONCLUSION: Dermatologic toxicities related to panitumumab are common; however, the way they are reported and managed varies among physicians. To prevent progression, toxicities must be assessed and treated early and aggressively, according to severity grading. Dermatologists could aid oncologists in choosing the best management strategies.

Pruritus in pregnancy: treatment of dermatoses unique to pregnancy.

QUESTION: Some of my pregnant patients complain about pruritus. Are there conditions in pregnancy that present with pruritus that might put the mother or fetus at risk? ANSWER: Although most cases of pruritus can be attributed to itchy dry skin, there are conditions unique to pregnancy that involve pruritus as a leading symptom. These include pemphigoid gestationis, pruritic urticarial papules and plaques of pregnancy, intrahepatic cholestasis of pregnancy, and atopic eruption of pregnancy. These conditions are associated with severe pruritus and some might be associated with adverse fetal outcomes. Clinical history and physical examination are the most important diagnostic clues when evaluating pruritus in pregnancy.

Patients Hospitalized with pH1N1 Influenza in an Academic Community Medical Center.

BACKGROUND: The emergence of a novel strain of pandemic influenza (pH1N1) in 2009 presented significant challenges to health care facilities worldwide. In our academic community medical center in suburban Philadelphia, we noted our first pH1N1 diagnosis in September 2009. We sought to assess the impact of pH1N1 disease on our hospitalized patient population. METHODS: We prospectively collected clinical and epidemiological data on 29 consecutive patients that were admitted to our hospital with a primary or secondary diagnosis of influenza from October 1-November 30, 2009. Data were obtained through care of the patients and chart review. RESULTS: Prominent symptoms on admission included fever, hypoxia, cough, myalgias, and diarrhea, with leukocytosis and neutrophilia. Pre-existing medical conditions included asthma, pregnancy, immunosuppressive therapy, and sickle cell disease. All but 5 of the patients were under 60 years of age. Three patients had culture-documented bacterial or mycoplasma infections. All but two of the patients received oseltamivir. Six required admission to the intensive care unit but only one patient died. CONCLUSIONS: Our population of hospitalized patients with novel pH1N1 influenza demonstrated many of the features that have been associated with pH1N1 disease in other populations. Most of the patients were women and none of the patients died directly as a complication of influenza. We observed a cluster of patients with a tetrad of features comprising a history of asthma, obesity, female gender, and African-American race. Individuals with this constellation of factors should be specifically targeted for pH1N1 vaccination.

A randomized trial to evaluate the efficacy of online follow-up visits in the management of acne.

OBJECTIVE: To evaluate whether delivering acne follow-up care via an asynchronous, remote online visit (e-visit) platform produces equivalent clinical outcomes to office care. DESIGN: A prospective, randomized controlled study. SETTING: Two teaching hospitals in Boston between September 2005 and May 2007. PARTICIPANTS: A total of 151 patients with mild to moderate facial acne. INTERVENTIONS: Subjects were asked to carry out 4 follow-up visits using either an e-visit platform or conventional office care. At 6-week intervals, subjects in the e-visit group were prompted to send images of their skin and an update, via a secure Web site, to their dermatologist. Dermatologists responded with advice and electronic prescriptions. MAIN OUTCOME MEASURES: The primary outcome measure was change in total inflammatory lesion count between the first and last visit. The major secondary outcomes were subject and dermatologist satisfaction with care and length of time to complete visits. RESULTS: The mean age of subjects was 28 years; most were female (78%), white (65%), and college educated (69%). One hundred twenty-one of the initial 151 subjects completed the study. The decrease in total inflammatory lesion count was similar in the e-visit and office visit groups (6.67 and 9.39, respectively) (P = .49). Both subjects and dermatologists reported comparable satisfaction with care regardless of visit type (P = .06 and P = .16, respectively). Compared with office visits, e-visits were time saving for subjects and time neutral for dermatologists (4 minutes, 8 seconds vs 4 minutes, 42 seconds) (P = .57). CONCLUSION: Delivering follow-up care to acne patients via an e-visit platform produced clinical outcomes equivalent to those of conventional office visits.

Remote assessment of acne: the use of acne grading tools to evaluate digital skin images.

Digital imaging of dermatology patients is a novel approach to remote data collection. A number of assessment tools have been developed to grade acne severity and to track clinical progress over time. Although these tools have been validated when used in a face-to-face setting, their efficacy and reliability when used to assess digital images have not been examined. The main purpose of this study was to determine whether specific assessment tools designed to grade acne during face-to-face visits can be applied to the evaluation of digital images. The secondary purpose was to ascertain whether images obtained by subjects are of adequate quality to allow such assessments to be made. Three hundred (300) digital images of patients with mild to moderate facial inflammatory acne from an ongoing randomized-controlled study were included in this analysis. These images were obtained from 20 patients and consisted of sets of 3 images taken over time. Of these images, 120 images were captured by subjects themselves and 180 were taken by study staff. Subjects were asked to retake their photographs if the initial images were deemed of poor quality by study staff. Images were evaluated by two dermatologists-in-training using validated acne assessment measures: Total Inflammatory Lesion Count, Leeds technique, and the Investigator's Global Assessment. Reliability of raters was evaluated using correlation coefficients and kappa statistics. Of the different acne assessment measures tested, the inter-rater reliability was highest for the total inflammatory lesion count (r = 0.871), but low for the Leeds technique (kappa = 0.381) and global assessment (kappa = 0.3119). Raters were able to evaluate over 89% of all images using each type of acne assessment measure despite the fact that images obtained by study staff were of higher quality than those obtained by patients (p < 0.001). Several existing clinical assessment measures can be used to evaluate digital images obtained from subjects with inflammatory acne lesions. The level of inter-rater agreement is highly variable across assessment measures, and we found the Total Inflammatory Lesion Count to be the most reliable. This measure could be used to allow a dermatologist to remotely track a patient's progress over time.
