The molluscum contagiosum BOTE sign-Infected or inflamed?

BACKGROUND: Molluscum contagiosum (MC) is a common skin infection in the pediatric age group. The infection is self-limited and manifests as discrete, umbilicated skin-colored papules on any skin surface of the body. At times, complications such as local dermatitis and swelling, erythema, and pus formation may appear. These signs of inflammation are commonly presumed to represent bacterial infection. METHODS: This multicenter study was a retrospective analysis of data collected on all patients diagnosed with inflamed lesions secondary to MC and treated at the Hadassah Medical Centers and Shaare Zedek Medical Center in Jerusalem, Israel, from 1/1/2008 to 1/07/2018. Characteristics of children with positive cultures were compared to those with negative cultures and those with contaminants. RESULTS: A total of 56 cases were reviewed; the mean age at presentation was 4.6 years. Fever was reported in 12.5%, and 62.5% received systemic antibiotics because of their inflamed MC prior to admission. Fifty-five percent had sterile cultures or cultures growing only contaminants. Only seven had positive cultures with the common cutaneous pathogens. No statistical difference was observed between the patients with pathogenic isolates and patients with sterile or non-pathogenic cultures in terms of demographics, lesion characteristics, inflammatory markers, or length of hospitalization. CONCLUSION: The findings suggest that most cases of suspected MC-related secondary infection can be attributed to inflammation rather than to bacterial infection. However, in some cases, true bacterial infection should be suspected and treated accordingly.

Predicting Weight Loss and Comorbidity Improvement 7 Years Following Laparoscopic Sleeve Gastrectomy: Does Early Weight Loss Matter?

BACKGROUND: Predicting the variables that affect the outcomes following laparoscopic sleeve gastrectomy (LSG) would allow focused resource allocation with a view to improving results. Whilst greater early post-operative weight loss following LSG is associated with greater short-term weight loss, the relationship between early results and long-term outcomes has not been described. METHODS: A retrospective cohort analysis was performed on patients who underwent LSG 7 years before a follow-up telephone interview was performed. Multivariate regression analysis was used to explore the relationship between early weight loss at 4 weeks following surgery and weight loss at 7 years. A non-inferiority analysis assessed whether early weight loss was associated with either improvement or resolution of hypertension or type 2 diabetes mellitus (T2DM) at 7 years after surgery. RESULTS: Of the 156 patients identified between April and October 2012, 130 (83.3%) met the inclusion criteria and were included in the analysis. The average preoperative BMI was 42.5 kg/m2 (standard deviation 5.2). The change in BMI was 4.6 kg/m2 (4.0) at 4 weeks and 12.2 kg/m2 (5.4) at 7 years. There was improvement or resolution in 19/31 (61.3%) patients with T2DM and 14/26 (53.8%) patients with hypertension. Whilst younger age was associated with greater weight loss at 7 years follow-up, no such relationship was identified with early post-operative weight loss. Early post-operative weight loss was also not associated with long-term improvement or resolution in hypertension or T2DM. CONCLUSIONS: Early weight loss does not appear to be associated with greater weight loss nor comorbidity improvement 7 years following LSG. TRIAL REGISTRATION: ClinicalTrials.gov (SZMC-95/19).
