Patient-centered digital healthcare for patients undergoing breast surgery-A cross-sectional questionnaire study.

INTRODUCTION: The potential of digital health services has become apparent in recent years, more so now following the coronavirus disease outbreak. However, despite majority of UK population integrating digital-based platforms into their everyday life, there is low engagement with NHS digital services, citing lack of patient-centered approaches to the design of such services. As such, this cross-sectional questionnaire aims to understand the patient perspective pertaining the utility of web-based information in aiding their breast cancer pathway at a large volume tertiary breast institute. METHODS: Adult patients attending the outpatients' post-operative follow-up clinic for any breast-related surgery were included. Questionnaires were provided from 1 August 2019 to 31 December 2019, focusing on awareness of the website, usage and usefulness of information offered relating to their breast surgery journey, with opportunities for open feedback. RESULTS: Of the 104 patients completed the questionnaire, 70% (n = 73) were unaware of the breast institute's website. Patients' wanted a wide range of information, including signposting to support groups and perioperative information such as patient experiences/journey on the operative day (n = 46, 44%/n = 60, 58%) and videos explaining procedures. The most frequent free text included requests for information regarding financial support and parking, and "signposting" to other support services. DISCUSSION: Patients welcome the breast services' website, but we need to improve awareness of this resource and include more holistic information, relating not only to their diagnosis and treatment but also to practical/support services they can access to make their patient journey smoother.

Topical lidocaine enhanced by laser pretreatment: a safe and effective method of analgesia for facial rejuvenation.

BACKGROUND: Injectable forms of anesthesia for nonsurgical facial rejuvenation, although efficacious, are uncomfortable for the patient. Preclinical studies have demonstrated that laser pretreatment at low energies enhances absorption of topical lidocaine. OBJECTIVES: The authors assess the safety and efficacy of laser-assisted transdermal delivery of topical anesthetic. METHOD: Ten patients were split into 2 groups (A and B). All patients received 15 g of BLT (20% benzocaine, 6% lidocaine, and 4% tetracaine triple anesthetic cream) for 20 minutes with no occlusion. Then the cream was removed and the first blood draw taken. Group A patients were pretreated with the full ablative laser and group B patients with a fractional ablative laser to the full face. A further 15 g BLT was applied for another 20 minutes. Group A patients then underwent full ablative laser treatment, and group B received fractionated ablative laser treatment. Blood draws were taken at 60, 90, 120, 180, and 240 minutes after the initial topical anesthetic application, and the serum was analyzed for lidocaine and monoethylglycinexylidide (MEGX) levels. Patients were asked to rate the pain felt at intervals during the procedure. RESULTS: No patient required supplemental nerve blocks. Pain scores were equivalent at the end of the first pass for both groups (P = .436). Group A patients had significantly lower pain scores at the start of the second laser treatment (P = .045), but pain scores became equivalent by the end (P = .323). Combined serum lidocaine and MEGX levels were significantly higher in group A patients up to 90 minutes (peak average of 0.61 µg/mL for group A and 0.533 µg/mL for group B; P = .0253), which corresponded to greater initial analgesic effect. CONCLUSIONS: Data from this study demonstrate that topical anesthetic for facial rejuvenation can be enhanced with laser pretreatment while maintaining safe blood serum levels. Further studies should examine optimal application amount and time to allow safe multipass facial rejuvenation without the need for invasive nerve blocks.

An in vivo histopathological comparison of single and double pulsed modes of a fractionated CO(2) laser.

INTRODUCTION: Studies examining the histopathological changes that occur in human skin following fractional laser treatment have been performed mainly in animals or abdominal tissue prior to abdominoplasty. This study looks at the effect of double pulse fractional CO(2) laser compared to single pulse treatments to assess differences in tissue injury in the face and abdomen. METHODS: Twelve healthy subjects randomized into two groups, had two 1 cm(2) areas (infraumbilical and forehead) treated with the fractional CO(2) laser (Deep Fx, Lumenis). Settings used were 15 mJ double pulse, and 30 mJ single pulse, 300 Hz, 10% density and compared to the historic control of 15 patients treated at 15 mJ single pulse [Bailey et al. (2011), Lasers Surg Med 43: 99-107]. Treated sites were biopsied and analyzed with H&E and TUNEL staining to measure width and depth of the microthermal zones (MTZ) of ablation. RESULTS: When comparing 15 mJ double pulse to single pulse there were significant differences both in depth (abdominal skin, P = 0.002 and facial skin, P = 0.001) and width (facial skin, P = 0.0002) of MTZ. When comparing double pulsing at 15 mJ with single pulsing at 30 mJ there were significant differences between MTZ depths in the abdomen (P < 0.01) but not in either the MTZ depth (P = 0.69) or the width in the face (P = 0.502). DISCUSSION: This study demonstrates the differences between histopathological laser injury patterns in the face compared to the abdomen when single pulsing is used. It also demonstrates that double pulsing at 15 mJ is statistically similar to single pulsing at 30 mJ in the face. We think this could have ramifications for clinical practice where by double pulsing at lower energies may result in better clinical outcomes than increasing energies or using multiple passes at single pulse. Clinical studies needs to be performed to investigate this further.

Treatment of angiokeratoma of the vulva with pulsed dye laser therapy.

Angiokeratoma of the vulva is relatively rare with few cases reported in the literature. The lesions are usually asymptomatic, but clinical presentations can include bleeding and vulval pruritus. Treatments for symptomatic cases include surgical excision, cryotherapy and argon or carbon dioxide laser therapy. We present a case series of patients who have been successfully treated with pulsed dye laser therapy. This was performed in the outpatient setting without the need for local anaesthesia. All patients had resolution of their symptoms. This treatment modality to our knowledge has not been reported in the literature.
