Demographic characteristics, clinical features, and optimal management of hospitalized patients with staphylococcal scalded skin syndrome.

BACKGROUND/OBJECTIVES: Optimal management of staphylococcal scalded skin syndrome (SSSS) has not been established. Clindamycin may benefit patients via inhibition of ribosomal toxin production, but resistance patterns suggest penicillinase-resistant penicillins or cephalosporins should be the first line. Our goal was to describe demographic and clinical characteristics of SSSS patients at our institution, delineate bacterial resistance patterns, and examine outcomes of varying therapeutic strategies in SSSS. METHODS: We performed a retrospective review of patients under the age of 18 with confirmed clinical SSSS diagnosis by the dermatology consult team at the University of North Carolina (UNC) Hospitals from January 2008 to April 2017. Median hospital and ICU length of stay (LOS) were compared using a Wilcoxon Rank Sum Test. RESULTS: We found 59 SSSS patients. Coverage with clindamycin and vancomycin versus absence of that combination was associated with shorter ICU LOS. Although trending toward reduced hospital LOS, this was not significantly altered with the use of vancomycin and clindamycin after adjustment for multiple comparisons. Individual use of either clindamycin or vancomycin did not significantly alter overall hospital or ICU LOS. Among 24 patients with a pathogen identified on culture, 18 (75.0%) revealed resistance to clindamycin, and 2 (8.3%) revealed MRSA. CONCLUSIONS: Clindamycin resistance is more prevalent in hospitalized SSSS patients compared to our pediatric outpatient population. The combination of vancomycin and clindamycin results in shorter ICU LOS. Individual use of clindamycin or vancomycin does not significantly reduce hospital or ICU LOS after adjustment for multiple comparisons.

Clearance of recalcitrant warts in a pediatric patient following administration of the nine-valent human papillomavirus vaccine.

Verruca vulgaris is a common, benign infection of the skin and mucous membranes caused by human papillomavirus (HPV). Although many therapeutic options for warts exist, they have limited efficacy and there is no definitive cure for warts. We report the case of a 10-year-old girl with recalcitrant cutaneous warts persisting more than two years which resolved completely following vaccination with the nine-valent HPV vaccine.

A cross-sectional study of medical students' knowledge of patient safety and quality improvement.

BACKGROUND: The Association of American Medical Colleges and the World Health Organization have endorsed formal patient safety and quality improvement (QI) education for medical students. We surveyed medical students to assess their current level of patient safety and QI knowledge and to identify factors associated with increased knowledge. METHODS: A literature review, focus groups with medical students, and local expert interviews were used to develop an electronic survey, which was distributed to all medical students at a single medical school in the spring of 2012. RESULTS: Fifty-seven percent of the medical school student body (N = 790) participated in the survey. A greater proportion of students reported previous exposure to patient safety education than to QI education (79% vs 47%). Students scored an average of 56% and 58% on the patient safety and QI knowledge tests, respectively. Having or pursuing an advanced degree (P = .02) and previous exposure to patient safety education (P = .02) were associated with higher knowledge scores. After adjusting for confounding variables, only previous exposure to QI education (P = .02) was associated with higher QI knowledge scores. LIMITATIONS: There is a risk of measurement bias due to the use of an unvalidated instrument. Students who have greater knowledge of patient safety or QI might recall exposure at a greater frequency, inflating the association between exposure and knowledge. Also, this is a cross-sectional study, so we cannot draw conclusions about causality. CONCLUSION: Medical students' knowledge of patient safety and QI is low. Previous formal or informal education about these topics is associated with increased knowledge.

Patient safety and quality improvement education: a cross-sectional study of medical students' preferences and attitudes.

BACKGROUND: Recent educational initiatives by both the World Health Organization and the American Association of Medical Colleges have endorsed integrating teaching of patient safety and quality improvement (QI) to medical students. Curriculum development should take into account learners' attitudes and preferences. We surveyed students to assess preferences and attitudes about QI and patient safety education. METHODS: An electronic survey was developed through focus groups, literature review, and local expert opinion and distributed via email to all medical students at a single medical school in the spring of 2012. RESULTS: A greater proportion of students reported previous exposure to patient safety than to quality improvement topics (79% vs. 47%). More than 80% of students thought patient safety was of the same or greater importance than basic science or clinical skills whereas quality improvement was rated as the same or more important by about 70% of students. Students rated real life examples of quality improvement projects and participation in these projects with actual patients as potentially the most helpful (mean scores 4.2/5 and 3.9/5 respectively). For learning about patient safety, real life examples of mistakes were again rated most highly (mean scores 4.5/5 for MD presented mistakes and 4.1/5 for patient presented mistakes). Students rated QI as very important to their future career regardless of intended specialty (mean score 4.5/5). CONCLUSIONS: Teaching of patient safety and quality improvement to medical students will be best received if it is integrated into clinical education rather than solely taught in pre-clinical lectures or through independent computer modules. Students recognize that these topics are important to their careers as future physicians regardless of intended specialty.

High-dose isotretinoin treatment and the rate of retrial, relapse, and adverse effects in patients with acne vulgaris.

IMPORTANCE: Isotretinoin is the most effective treatment for acne. The ideal dosing regimen is unknown. OBJECTIVE: To determine the rates of relapse of acne vulgaris and retrial of isotretinoin after high cumulative-dose treatment and the changes to the adverse effect profile. DESIGN, SETTING, AND PARTICIPANTS: A prospective, observational, intervention study was conducted from August 1, 2008, to August 31, 2010, in a single academic tertiary care center with multiple providers. A total of 180 patients with acne resistant to other treatments were enrolled. Of these, 116 participated in the 12-month follow-up survey, for a response rate of 64.4%. EXPOSURE: Patients received isotretinoin, with dosing based on the providers' judgment. Patients were divided into 2 groups on the basis of cumulative dosing (<220 mg/kg and ≥ 220 mg/kg). MAIN OUTCOMES AND MEASURES: Relapse (treatment with a prescription topical or oral acne medication after a course of isotretinoin) or retrial (retreatment with isotretinoin) at 12-month follow-up and adverse effects experienced during and after 12 months of treatment. RESULTS The mean age of the participants was 19.3 years, 51.9% were female, and 74.1% were white. At 12 months' follow-up, 97.4% of the patients reported that their acne was improved. Overall, acne in 32.7% of patients in the study relapsed at 12 months, and 1.72% of the patients required a retrial. In the lower-dose treatment group (<220 mg/kg), the relapse rate was 47.4% (95% CI, 32.3%-63.0%) compared with 26.9% (95% CI, 18.3%-37.8%) in the high-dose group (P = .03). Almost 100% of the patients in both treatment groups developed cheilitis and xerosis during treatment. Retinoid dermatitis was significantly more common in the high-dose treatment group (53.8% vs 31.6%; P = .02). None of the other adverse effects was significantly different between the 2 groups. CONCLUSIONS AND RELEVANCE: The dosing regimen used in the present study is considerably higher than that used in previous studies of isotretinoin. At 1 year after completion of isotretinoin treatment, we found that patients receiving 220 mg/kg or more had a significantly decreased risk of relapse. Rash was the only adverse effect that was significantly more common in the high-dose group during treatment. This study suggests that significantly higher doses of isotretinoin are effective for treating acne and decreasing relapse rates without increasing adverse effects.
