RESUMO
This is the second part of a two-part series summarizing the latest evidence related to suture materials and wound closure techniques in dermatological surgery. We critically appraised evidence focusing on the following consequences of suture choice: scar/cosmesis, pain, patient satisfaction, cost, infection and wound complications. We searched the databases MEDLINE, PubMed and Embase using the keywords 'skin surgery', 'dermatological surgery', 'sutures', 'braided sutures', 'monofilament sutures' and 'antibacterial sutures' to identify relevant English-language articles. This part of the review assesses the evidence for different types of buried sutures, including braided vs. monofilament sutures, longer-absorbing sutures and antibacterial sutures. The majority of trials were noted to be of poor quality, single-centre (thus lacking external validity) and underpowered, which presents challenges in comparing suture techniques in skin surgery. Future large-scale, multicentre, randomized trials are needed, with both surgeon and patient-assessed validated outcomes.

Significant variation exists in the surgical suture materials and techniques used for dermatological surgery. Many wound-closure techniques are now practised, including use of sutures, staples and topical adhesives. The focus of our review article is to summarize the latest evidence relating to suture materials and wound-closure techniques, considering the following areas: scar/cosmesis, pain, patient satisfaction, cost, infection and wound complications. We searched the databases Medline, PubMed and Embase using the keywords 'skin surgery', 'dermatologic surgery', 'sutures', 'suture techniques', 'suturing techniques' and 'surgical techniques' to identify relevant English-language articles. Absorbable superficial sutures may be a preferred alternative to nonabsorbable sutures by both patients and surgeons. Subcuticular sutures may be preferable to simple interrupted sutures for superficial wound closure, and there may also be a role for skin staples in dermatological surgery, particularly on the scalp. However, there remains limited evidence specific to dermatological surgery supporting the use of particular suture materials and suturing techniques. Further high-quality research is required, including multicentre randomized trials with larger cohorts.

Consent must be undertaken prior to any dermatological procedure; however, in doing this, the clinician needs to ensure consent is valid and satisfies the principles of determining material risk. We aimed to assess variations in obtaining consent in the UK and understanding of material risk through a nationally distributed survey to members of the British Society for Dermatological Surgery and British Association of Dermatologists. Of 165 responses, we found that written consent was being obtained for all procedures in 73.9% of cases and typically at the time of procedure in the operating room/theatre (78.8%). Fifty-seven per cent of respondents were not familiar with the term 'material risk' and almost one-third were not aware of the Montgomery vs. Lanarkshire ruling, which replaced the Bolam test in 2015. We would encourage readers to be aware of these changes to consent law in the UK and how it might affect their approach to obtaining consent.

AIM: Rueter et al. aimed to 'determine the effects of early postnatal vitamin D supplementation on infant eczema and immune development'. SETTING AND DESIGN: This was a double-blind randomized placebo-controlled trial with an additional nonrandomized exploratory analysis on the effects of ultraviolet (UV) exposure led from a hospital setting. STUDY EXPOSURE: Vitamin D (400 iU daily) drops or placebo drops (coconut and palm kernel oil) were allocated randomly to 195 infants born to families with a first-degree relative with atopic disease. Eighty-six of these infants were allocated personal UV dosimeters in a nonrandomized fashion to measure UV light (290-380 nm) exposure until 3 months of age. OUTCOMES: Eczema and wheeze were assessed at 3 and 6 months, and 25 immune function markers were assessed at 6 months of age. Infant vitamin D levels and immune functions were measured at 6 months of age. RESULTS: Although vitamin D levels were significantly greater in infants in the intervention group than in those in the placebo group at 3 and 6 months of age, there was no difference in eczema between groups at either time point (10·0% vs. 6·7% at 3 months and 21·8 vs. 19·3% at 6 months for the vitamin D and placebo groups, respectively). In the subset of infants given a dosimeter, those with eczema had less UV light exposure (median 555 J m-2 ) than infants who did not develop eczema (median 998 J m-2 ). Across the 25 immune functions, UV light exposure was inversely correlated with interleukin-2, granulocyte macrophage colony-stimulating factor and eotaxin production by Toll-like receptor ligands. CONCLUSIONS: Vitamin D supplementation in high-risk infants increased vitamin D levels but did not reduce eczema. Exploratory post-hoc analyses in a nonrandomized subset showed an association between greater direct UV light exposure and reduction of eczema. The authors claim that their 'findings indicate that UV light exposure appears more beneficial than vitamin D supplementation as an allergy prevention strategy in early life'.

This review forms part of a series of annual updates that summarize the evidence base for atopic eczema (AE). It provides a summary of key findings from 25 systematic reviews that were published or indexed during 2017, and focuses on the treatment and prevention of AE. There is high-quality evidence to demonstrate that dupilumab is better than placebo for the treatment of AE, is not associated with a higher incidence of adverse effects and does not increase the risk of infection compared with placebo; however, comparison studies with other systemic treatments are necessary. Topical tofacitinib is a promising treatment for mild-moderate AE, but currently lacks sufficient evidence from well-designed randomized controlled trials (RCTs) comparing with other active treatments. Topical doxepin may be effective for pruritus in AE, but available studies have short follow-up periods and longer-term outcomes are needed. Bleach baths were no more effective than water baths alone at reducing AE severity. Topical antibiotics cannot be recommended for infected AE, owing to insufficient evidence of benefit. There is little comparison of different emollients in RCTs, but overall evidence indicates that they reduce AE severity, are steroid-sparing and lead to better outcomes in combination with topical corticosteroids (TCS) than TCS alone. No clear benefit was demonstrated for vitamin D/C/E supplementation in pregnancy for eczema prevention.

BACKGROUND: Biofilms are diverse groups of microorganisms encased in a self-produced matrix that offers protection against unfavorable conditions and antibiotics. METHODS: We performed a literature search using the MEDLINE electronic database. Only original articles published in English were considered for review. RESULTS: Biofilms have been implicated in the pathogenesis of acne, eczema, hidradenitis suppurativa, onychomycosis, miliaria, and impetigo. Adverse dermal-filler reactions are also linked to biofilms. Strict aseptic technique and prophylactic antibiotics are recommended in order to avoid such complications. Finally, biofilms are implicated in wounds, mainly chronic and diabetic, where they impede healing and cause recurrent infections. Several novel anti-biofilm agents and wound debridement have been shown to be beneficial. CONCLUSIONS: Biofilms are a significant cause of disease with wide implications in the field of dermatology. Several novel treatments have been found to be effective against biofilms, depending on the underlying microbes and type of disease.

OBJECTIVE: Dedicated otolaryngology high dependency units are uncommon. This paper reports the first experiences of such a facility in the UK, assessing reason for admission, duration of stay, occupancy rate and need for care escalation. The study sought to assess the presence of similar units in the UK. METHODS: A retrospective review of high dependency unit admissions over an 18-month period and a national survey of otolaryngology departments in the UK were conducted to establish the overall presence and location of similar high dependency units. RESULTS: A total of 128 patients were admitted during the study period, mainly following surgery and because of airway compromise. The average duration of stay was 2-3 days (range, 1-12 days). The occupancy rate was 31.7 per cent. No patients required their care to be escalated to the intensive care unit. Seven similar high dependency units were identified in the UK. CONCLUSION: The care provided prevented the need for escalation of care to an intensive care unit. This challenges the need for patient management on intensive care units following major surgery or airway compromise for those not requiring assisted ventilation. High dependency units similar to ours are not widespread.

We report a case of Epidermolysis Bullosa Acquisita (EBA) that presented as a diagnostic challenge. A 60-year-old Qatari lady presented with odynophagia, oral ulceration, and weight loss. Multiple physicians investigated her for over 6 months with a multitude of tests and serial gastroscopies, all of which failed to reach a conclusive diagnosis. Only after referral to a dermatologist and full body examination was diagnosis finally achieved. After reviewing the literature, we provide a summary of EBA and highlight the importance of comprehensive clinical reviews in order to avoid unnecessary morbidity.
