Preferences for Prophylactic Oral Antibiotic Use in Dermatologic Surgery: A Multicenter Discrete Choice Experiment.

BACKGROUND: Antibiotics are often prescribed after dermatologic surgery for infection prophylaxis, but patient preferences about prophylactic antibiotics are not well understood. OBJECTIVE: To understand patient preferences about taking antibiotics to prevent surgical site infection (SSI) relative to antibiotic efficacy and antibiotic-associated adverse drug reactions. MATERIALS AND METHODS: Multi-center, prospective discrete choice experiment (DCE). RESULTS: Three hundred thirty-eight respondents completed the survey and DCE. 54.8% of respondents preferred to take an antibiotic if it reduced the SSI rate from 5% to 2.5% and if the risk of adverse drug reactions was low (1% risk gastrointestinal upset, 0.5% risk itchy skin rash, 0.01% risk emergency department visit). Even if an antibiotic could eliminate SSI risk (0% risk SSI) and had a low adverse drug reaction profile, 26.7% of respondents prefer not to take prophylactic oral antibiotics. CONCLUSION: Risk-benefit thresholds for taking antibiotics to prevent SSI vary widely. Clinical trials are needed to better characterize the effectiveness and risks of oral antibiotic SSI prophylaxis to guide decision-making. Future studies should also evaluate whether shared decision-making can improve the patient experience.

Prospective Randomized Controlled Trial on the Effects of Almonds on Facial Wrinkles and Pigmentation.

BACKGROUND: Almonds have long been studied as a rich source of fatty acids, phytochemical polyphenols and antioxidants such as vitamin E. A recent study compared almond supplementations to a calorie-matched intervention for 16 weeks, yielding statistically significant improvement in wrinkle severity in postmenopausal women with Fitzpatrick skin types I and II that received almonds. This study furthers that assessment with a larger population and duration of 24 weeks to assess the influence of almond consumption on wrinkle severity, skin pigmentation and other skin biophysical profiles. OBJECTIVE: To investigate the effects of almond consumption on photoaging such as wrinkles and pigment intensity as well as facial biophysical parameters such as sebum production, skin hydration and water loss. DESIGN AND INTERVENTIONS: A prospective, randomized controlled study assessed postmenopausal women with Fitzpatrick skin types I or II who consumed 20% of their daily energy consumption in either almonds or a calorie-matched snack for 24 weeks. A facial photograph and image analysis system was used to obtain standardized high-resolution photographs and information on wrinkle width and severity at 0, 8, 16 and 24 weeks. Measurements of transepidermal water loss (TEWL), skin pigmentation, skin hydration and sebum production were also completed at each visit. RESULTS: The average wrinkle severity was significantly decreased in the almond intervention group at week 16 and week 24 compared to baseline by 15% and 16%, respectively. Facial pigment intensity was decreased 20% in the almond group at week 16 and this was maintained by week 24. There were no significant differences in skin hydration or TEWL in the almond group compared to the control, although sebum excretion was increased in the control group. CONCLUSION: The daily consumption of almonds may improve several aspects of photoaging such as facial wrinkles and pigment intensity in postmenopausal women. In conclusion, the daily consumption of almonds may contribute to the improvement of facial wrinkles and reduction of skin pigmentation among postmenopausal women with Fitzpatrick skin types I and II.

Patient perceptions about nutrition and skin health: a survey study characterizing patient opinions and information resources.

BACKGROUND: Numerous studies in the clinical literature have explored the link between nutrition and skin physiology. However, it is unclear whether patients visit their dermatologists with knowledge of these studies, and unknown where they obtain their skin health information. We characterized patient perceptions surrounding nutrition and skin, including what patients identified as aggravating and alleviating foods and their information sources. METHODS: We administered a questionnaire to 409 participants attending University of California (UC) Davis Dermatology and Pacific Skin Institute in Sacramento. This survey assessed their perception on the influence of nutrition. We stratified responses by diseases. RESULTS: Of the 409 respondents, 83% believed that nutrition affects skin health. Respondents with healthy skin were not more likely to agree than those with skin conditions in general (P=0.34). Those with skin conditions also more likely received their information from reputable sources, defined as physicians and scientific journals (P=0.02). Additionally, respondents who disagreed were more likely informed by reputable sources (P=0.002), but when online blogs were included as reputable, this relationship was less significant (P=0.046). CONCLUSIONS: As online resources become more accessible, it is important for providers to know about changing patient perspectives. Our findings may help improve how dermatologists counsel patients about nutrition.

Alternative Treatment Approaches to Small Intestinal Bacterial Overgrowth: A Systematic Review.

Background: Broad-spectrum antibiotics are the first-line treatment for small intestinal bacterial overgrowth (SIBO). However, many antibiotics have a considerable side-effect profile and SIBO commonly reoccurs after successful eradication with antibiotics. Alternative therapies such as probiotics, therapeutic diets, and herbal medicines have been used to individualize SIBO management, particularly in recalcitrant cases. Objectives: The objective of this review is to evaluate the role of alternative therapies in SIBO treatment. Data Sources: EMBASE, MEDLINE, and the Cochrane Central Register were systematically searched for clinical studies evaluating alternative therapies in the management of SIBO. Study Eligibility Criteria: Human studies in which an alternative intervention was used to treat SIBO were included. Alternative interventions were defined as an intervention that included a probiotic supplement, herbal preparation, or a dietary change. Randomized controlled trials (RCTs), nonrandomized clinical trials with or without a control, and crossover studies were included. Study Appraisal: The following information was extracted from the selected studies: study type, study participants, SIBO subtype, intervention, comparison, outcome measures, relevant results, relevant side effects, and Jadad score. Results: Eight studies met inclusion criteria. The studies evaluated probiotics (n = 5), therapeutic diet (n = 1), and herbal medicines (n = 2). Among these studies, there were four RCTs, two open-label single-arm studies, one randomized, double-blind crossover study, and one two-arm open-label study with crossover. Main results are summarized. Limitations: There may be studies not captured by the defined search criteria. Additionally, studies used different methodologies in both breath testing and measurement of clinical symptoms, making it difficult to draw conclusions on SIBO eradication and symptom improvement across studies. Conclusions and Implications: Our findings suggest preliminary evidence for a role of alternative therapies in the treatment of SIBO. However, robust clinical trials are generally lacking. Existing studies tend to be small and lack standardized formulations of treatment. Breath testing protocols and clinical symptom measurement greatly varied between studies. Large-scale, randomized, placebo-controlled trials are needed to further evaluate the best way to utilize alternative therapies in the treatment of SIBO.

5-0 Polypropylene versus 5-0 fast absorbing plain gut for cutaneous wound closure: a randomized evaluator blind trial.

Mixed opinions exist regarding cosmetic outcomes of 5-0 fast absorbing plain (FG) gut relative to nonabsorbable suture material, such as 5-0 polypropylene (PP). High quality randomized trials comparing these two suture materials are lacking. To determine whether the use of PP during layered repair of linear cutaneous surgery wounds improves scar cosmesis compared to wound closure with FG. A randomized, split wound, comparative effectiveness trial was undertaken. Patients were evaluated 3 months after the intervention by two blinded physicians using the validated patient observer scar assessment scale (POSAS). Patient assessments were also captured using the same instrument as well as scar width and complications. The mean sum of the six components of the POSAS was 10.26 vs 12.74 for PP and FG, respectively, significantly (p < 0.001) in favor of PP. Mean observer overall opinion similarly showed better outcomes for PP than for FG [1.88 vs 2.52, respectively (p < 0.006)]. The mean sum of the patient assessed components of the POSAS for PP and FG was 12.3 vs 14.34, respectively (p = 0.11). Patient overall opinion significantly favored PP (2.41 vs 3.14, p = 0.043). PP resulted in small but statistically significant better cosmetic outcomes than FG. Pain experienced during suture removal was minimal for most patients.
