Local anaesthetics in dermatological surgery: a review of adjuncts and pain reduction techniques.

A variety of adjuncts for local anaesthesia (LA) exists for dermatological surgery, along with many options to reduce the pain of LA. This review aims to summarize the evidence relating to such adjuncts and methods to reduce the pain of LA. Adjuncts to LA can be an important consideration to optimize anaesthetic effect. Current evidence suggests that buffering and warming of LA fluid, along with cooling, pinching and administering vibrations to the skin are effective at reducing pain during administration. In this review, no significant difference in pain reduction was found between cooling and administering vibrations to the skin. Studies demonstrate that, overall, LA injection into distal sites is safe. However, the evidence specific to dermatological surgery is limited with regard to ways to reduce pain during LA injection and in determining the safety of LA for distal sites with confidence. Further high-quality research in the form of multicentre randomized controlled trials is required.

A multicentre qualitative study of patient skin surgery experience during the COVID-19 pandemic in the UK.

Understanding patient concerns regarding skin surgery during the COVID-19 pandemic is a vital way of learning from individual experiences. A shift towards using superficial absorbable sutures (AS) has been anecdotally observed. We explored patient attitudes to the use of AS, and their experiences and perceptions of attending for skin surgery during the pandemic. In total, 35 participants were interviewed (74% men, 100% white British; mean age 72.5 years, range 43-95 years). Participants reported that they were reassured by precautions taken to minimize exposure and risk from COVID-19. The majority (86%) did not feel that personal protective equipment worn by staff impaired their experience, and 29% reported that their experience of attending for skin surgery during the lockdown period was more efficient and organized than on prepandemic visits. The vast majority (94%) of participants would opt to have AS again or had no strong preference for either suture type. Based on their experiences, most participants would have no concerns about attending for further skin surgery during the pandemic and would opt to have AS.

Pachydermodactyly presenting as juvenile idiopathic arthritis in an adolescent man.

We present the case of a 17-year-old Asian man diagnosed with pachydermodactyly, a rare digital fibromatosis. Although this is a non-inflammatory periarticular soft tissue disorder, the clinical appearance can mimic inflammatory arthritis. The patient had a 2-year history of fusiform swelling of multiple proximal interphalangeal joints. He was initially diagnosed with juvenile idiopathic arthritis and treated with methotrexate, but a lack of clinical response led to the diagnosis of pachydermodactyly. Recognising this rare condition can prevent unnecessary and potentially harmful treatment.

Chemotherapy-related striate melanonychia: a case report.

BACKGROUND: Chemotherapy medications are reported to cause discoloration of the nails known as melanonychia. Depending on the nail structure affected and the severity of the insult, the clinical features can be variable. There are a great deal of unreported cases of pigmentary nail changes associated with chemotherapy treatment. By sharing our knowledge, we hope to raise the awareness of these nail changes amongst clinicians. Early recognition is crucial to allay anxiety among patients and avoid any unnecessary investigations. CASE PRESENTATION: We present a case of 36-year-old woman of south Asian origin, who developed dark pigmentation in the left thumb nail during neoadjuvant chemotherapy with 5-fluorouracil, epirubicin, cyclophosphamide, and docetaxel (FEC-D) for triple negative breast cancer. Upon examination, the left thumb nail pigmentation was strikingly linear, uniform, and well demarcated extending from proximal nail fold to free margin. Despite the reassuring clinical features, the patient was understandably anxious that this could be a presentation of acral melanoma and was referred to the plastic surgeons for a nail matrix biopsy. Biopsy reassuringly was reported as melanosis and a diagnosis of striate melanonychia was made. The patient was discharged after 2-year follow-up. CONCLUSION: Chemotherapy medications have improved survival rates and patient outcomes. It is important for clinicians to be aware of the association of melanonychia with certain chemotherapy medications to reduce anxiety and allow successful management of these patients without delay. Striate melanonychia in this patient was felt most likely due to the synergistic effect of chemotherapy drugs compounded with racial predisposition. Chemotherapy agents most likely to have contributed include cyclophosphamide, docetaxel, and 5-fluorouracil.
