RESUMO

In this study, a soft-tissue-anchored, percutaneous port used as a mechanical continence-preserving valve in reservoir ileo- and urostomies was functionally and morphologically evaluated in eight dogs. During follow-up, the skin failed to attach to the implant, but the intestine inside the stoma port appeared to be attached to the mesh. After reaching adequate reservoir volume, the urostomies were rendered continent by attaching a lid to the implant. The experiments were ended at different time intervals due to implant-related adverse events. In only one case did the histological evaluation reveal integration at both the implant-intestine and implant-skin interfaces, with a low degree of inflammation and the absence of bacterial colonisation. In the remaining cases, integration was not obtained and instead mucosal downgrowth and biofilm formation were observed. The skin-implant junction was characterised by the absence of direct contact between the epidermis and the implant. Varying degrees of epidermal downgrowth, granulation tissue formation, inflammatory cell infiltration and bacterial growth and biofilm formation were prominent findings. In contrast, the subcutaneously located anchor part of the titanium port was well integrated and encapsulated by fibrous tissue. These results demonstrate the opportunity to achieve integration between a soft-tissue-anchored titanium port, skin and intestine. However, predictable long-term function could not be achieved in these animal models due to implant- and non-implant-related adverse events. Unless barriers at both the implant-skin and implant-intestine junctions are created, epidermal and mucosal downward migration and biofilm formation will jeopardise implant performance.

RESUMO

Characterization of patients, surgery procedures and the risk factors for dermatofibrosarcoma protuberans (DFSP) recurrences is poorly defined. In this study, we aimed to describe the demographics, tumor characteristics and interventions of DFSP treated with Mohs micrographic surgery (MSS) to determine the rate and risk factors for recurrence. Data were collected from REGESMOHS, a nationwide prospective cohort study of patients treated with MMS in Spain. From July 2013 to February 2020, 163 patients with DFSP who underwent MMS were included. DFSP was mostly located on trunk and extremities. Recurrent tumors had deeper tumor invasion and required higher number of MMS stages. Paraffin MMS was the most frequently used technique. Overall recurrence rate was 0.97 cases/100 person-years (95% IC = 0.36-2.57). No differences were found in epidemiological, tumor, surgery characteristics or surgical technique (frozen or paraffin MMS [p = 0.6641]) in terms of recurrence. Median follow-up time was 28.6 months with 414 patient-years of follow-up. In conclusion, we found an overall low recurrence rate of DFSP treated with MMS. None of the studied risk factors, including MMS techniques, was associated with higher risk for recurrence.

RESUMO

Though known as a medicinal herb for centuries, the recent legalization of cannabinoids across many states has ushered in a new era where cannabinoids have become a popular treatment option among clinicians and patients alike. Cannabinoids have demonstrated efficacy in wound healing, reducing inflammation, ameliorating pain, and have shown potential as an antitumor agent. As a result, cannabinoids have been rapidly woven into the fabric of modern medicine. However, the utility of cannabinoids in dermatologic surgery has not been explored to date. In this article, we review the current literature to discuss the potential impact of cannabinoid use in dermatologic surgery.

RESUMO

BACKGROUND: Merkel cell carcinoma (MCC) management typically includes surgery with or without adjuvant radiation therapy (aRT). Major challenges include determining surgical margin size and whether aRT is indicated. OBJECTIVE: To assess the association of aRT, surgical margin size, and MCC local recurrence. METHODS: Analysis of 188 MCC cases presenting without clinical nodal involvement. RESULTS: aRT-treated patients tended to have higher-risk tumors (larger diameter, positive microscopic margins, immunosuppression) yet had fewer local recurrences (LRs) than patients treated with surgery only (1% vs 15%; P = .001). For patients who underwent surgery alone, 7 of 35 (20%) treated with narrow margins (defined as ≤1.0 cm) developed LR, whereas 0 of 13 patients treated with surgical margins greater than 1.0 cm developed LR (P = .049). For aRT-treated patients, local control was excellent regardless of surgical margin size; only 1% experienced recurrence in each group (1 of 70 with narrow margins ≤1 cm and 1 of 70 with margins >1 cm; P = .56). LIMITATIONS: This was a retrospective study. CONCLUSIONS: Among patients treated with aRT, local control was superb even if significant risk factors were present and margins were narrow. We propose an algorithm for managing primary MCC that integrates risk factors and optimizes local control while minimizing morbidity.

RESUMO

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.

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.

RESUMO

BACKGROUND: Tie-over dressings are frequently used for skin grafts. Although a dressing is necessary for split-thickness skin grafts, their use in full-thickness skin grafts (FTSGs) is questionable. OBJECTIVE: This review was conducted to investigate the influence of different tie overs and dressings on graft take for FTSGs in cutaneous surgery. MATERIALS AND METHODS: An electronic database search was performed in MEDLINE, EMBASE, Web of Science, and the Cochrane library. The following search terms and comparable were used: skin transplantation, tie-over, fixation, sutures, and take. RESULTS: Fifteen articles met the inclusion criteria. Eight studies describe no use of a tie-over dressing for FTSGs. Dressing types included antibacterial dressings, foam or sponges, and bolsters. The lowest graft take was 80% (with a tie-over dressing). The highest graft take was 100% (with and without a tie-over dressing). CONCLUSION: The results show that, regardless of the technique used, the overall graft success rate is high. Although a definite recommendation could not be made, it seems that a graft without a tie-over dressing can suffice in certain circumstances.

RESUMO

BACKGROUND: Extramammary Paget disease (EMPD) poses treatment challenges. Invasive and noninvasive treatment modalities exist with variable success reported. Reflectance confocal microscopy (RCM) is emerging as an adjuvant diagnostic tool. OBJECTIVE: To evaluate the treatment of EMPD patients and the role of RCM. METHODS: Prospective study. Demographic and tumor characteristics were recorded. Handheld-RCM was performed and correlated with histology. Treatment, clearance, pathology, and follow-up were all recorded. RESULTS: Thirty-six EMPD lesions in 33 patients were included. Mean age was 71.7 years, and 23 were men. Mean number of surgical stages needed to clear margins was 1.9 (SD, 0.9; 1.0-3.0 stages), and mean margin needed to clear was 1.8 cm. Reflectance confocal microscopy correlated well with scouting punch biopsies (kappa, 0.93; p < .001). Disruption of the dermoepidermal junction was associated with invasive EMPD versus in situ (83.3% vs 25.9%) on histology (p = .01). LIMITATIONS: Relatively small sample size. CONCLUSION: Extramammary Paget disease is challenging, and lesion demarcation is of the utmost importance. Using a staged surgical excision approach, the mean margins needed were 1.8 cm, less than previously reported. Nonsurgical modalities, including radiation therapy, imiquimod, or photodynamic therapy can be considered if surgery is not pursued. Reflectance confocal microscopy is a valuable noninvasive imaging modality for the management of EMPD.

RESUMO

BACKGROUND: Glomus tumors are benign neurovascular neoplasms, most commonly located in the subungual region. These subcutaneous nodules are characterized by intense pain and temperature sensitivity. Although surgical excision is the curative treatment, permanent nail deformity and recurrence are not uncommon after conventional surgery. OBJECTIVE: This study evaluated the long-term efficacy of a modified transungual approach with nail preservation for removing subungual glomus tumors. MATERIAL AND METHODS: Thirty-nine patients with clinically diagnosed and histopathologically proven glomus tumors treated at a medical center over a 13-year period (2007-2019) were retrospectively evaluated. RESULTS: The 39 patients included 28 women and 11 men (ratio, 2.5:1), with a mean age of 48.9 years. Thirty-four tumors were located in the fingers and 5 in the toes. All patients returned to normal activity soon after the surgery. At a mean follow-up of 28.8 months, all were pain free or experienced minimal pain and were satisfied with treatment outcomes. One patient (2.6%) experienced recurrence. No nail deformity was observed. CONCLUSION: The transungual approach with nail plate preservation is a novel and effective method for removing subungual glomus tumors with reduced postoperative pain and rapid healing, while preserving or improving the configuration of the nail.

RESUMO

BACKGROUND: Dermatologists have the opportunity to provide medically necessary procedures, including laser hair removal, to transgender patients for gender affirmation. Further research is required to better assess the unique dermatologic needs of this population. OBJECTIVE: To examine the prevalence of dermatologic procedures among transgender people in the context of gender-affirming treatment. METHODS: This cross-sectional study examined survey responses from 696 transgender persons enrolled in the Study of Transition, Outcomes, and Gender cohort. Prevalence of self-reported dermatologic procedures was examined and compared across participant subgroups. RESULTS: Electrolysis was the most commonly reported procedure (32.9%). Transfeminine patients were more likely to use dermatologic procedures compared with transmasculine patients. Only 19 participants (2.8%) reported the use of dermal filler injections. CONCLUSION: Differences in utilization of dermatologic procedures were noted in transgender populations. Motivations, barriers, and optimal timing for gender-affirming dermatologic procedures among transgender persons should be examined in future studies.

RESUMO

BACKGROUND: Nonpigmented intradermal melanocytic nevi (IMN) are benign lesions often removed for cosmetic reasons. There is no consensus as to the best technique for IMN excision. OBJECTIVE: To compare cosmetic outcomes and risk of recurrence after shave excision versus elliptical excision of IMN. MATERIALS AND METHODS: In this randomized clinical trial, patients underwent shave excision or elliptical excision with sutured closure of IMN of the face or back. Recurrence, patient satisfaction, cosmetic outcome, postoperative discomfort, scar size, discoloration, and presence of hypertrophic or keloid scars were evaluated at 3, 6, and 9 months. RESULTS: Overall, 145 nevi were removed from 45 patients (86.7% women, mean age 52.1 ± 12.5 years). The recurrence rate was 11.7%, occurring only after shave excision; 94.1% of recurrences were observed at 3-month follow-up. Shave excision was associated with less discomfort 48 hours after intervention but a greater likelihood of involved lateral and deep margins (p < .001). Scars were larger after elliptical excision and suture than after shave excision (p < .01). The mean patient satisfaction was higher in the shave excision group (p < .004). CONCLUSION: Shave excision of IMN is associated with higher rates of involved surgical margins and recurrence than elliptical excision but provides superior cosmesis and patient satisfaction.

RESUMO

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a rare low-grade tumor that typically does not metastasize but often recurs. Fibrosarcomatous DFSP (FS-DFSP) is associated with a substantially higher rate of metastasis and a poorer prognosis. OBJECTIVE: This study sought to investigate the epidemiological, histopathological, and clinical characteristics of DFSP, especially with a particular focus on FS-DFSP. MATERIALS AND METHODS: Clinical data from 254 patients treated between January 1999 and July 2018 were retrospectively reviewed. Endpoints of the study were the incidence of significant disease-related clinical events. RESULTS: Follow-up data from 211 patients were available for analysis, with a median follow-up time of 38 months (range: 1-196 months). The 5-year recurrence-free survival rate of patients underwent wide-local excision (WLE) was 97.1%. Patients underwent WLE exhibited a significantly decreased recurrence rate relative to patients treated through local excision (2.9% vs 37.7%; p < .001). Fibrosarcomatous DFSP had significantly higher rates of distant metastasis (66.7% [n = 4] vs 2.0% [n = 4]; p < .001) and long-term mortality (50.0% [n = 3] vs 1.5% [n = 3]; p < .001), compared with classical DFSP (C-DFSP). CONCLUSION: Wide-local excision is an effective means of reducing DFSP recurrence. Rates of metastasis are higher for FS-DFSP than for C-DFSP, with the former having significantly poorer outcomes.

RESUMO

BACKGROUND: Treatment practices vary for lentigo maligna (LM). Staged excision with circumferential margin control (SECMC) has the potential to achieve low recurrence rates. OBJECTIVES: To evaluate the clinical outcomes of SECMC using permanent, paraffin-embedded sections and delayed reconstruction. METHODS: We conducted a retrospective, uncontrolled, observational cohort study involving patients who underwent staged excision for LM of the head and neck at Women's College Hospital in Toronto, Canada, from September 2010 to March 2013. Recurrence and infection rates were ascertained from patient charts and postal surveys. RESULTS: One hundred and two patients (45 female, 57 male) were included with a median follow-up time of 1410.5 (IQR 260-1756) days. The median age was 69 (IQR 61-79) years. Approximately one-fifth (21%, 21/102) of patients required greater than 0.5 cm margins to achieve histological clearance. One patient (1/102) upstaged to invasive melanoma based on the initial stage of excision. The infection rate was 6% (6/102) and the 5-year cumulative recurrence rate was 1.4% (95% CI 0.2-9.6%). CONCLUSION: SECMC using permanent sections and delayed reconstruction appears to be a safe and effective treatment method for LM on the head and neck. Randomized trials are needed to help define the optimal treatment.

RESUMO

PURPOSE: The right choice of dressing after skin grafting, especially in the anatomically complex and aesthetically important head and neck area, is difficult. It is important to have a dressing which is durable and doesn't need a lot of dressing changes. This study introduces a novel, individually moulded silicon dressing; and investigates the number of dressing changes, durability of the dressing and the aesthetic outcome of patients receiving this new type of dressing, in comparison to a control group. MATERIALS AND METHODS: The present retrospective single center controlled case series study reports our experiences using two different types of dressing on patients undergoing full thickness skin grafts in the head during the period 01 May 2016 to 01 May 2020. Data were analysed according to the type of dressing with either a transparent moulded silicone dressing or an established silicone sheet dressing. RESULTS: 52 patients were included in the study. We found no difference in the aesthetic outcome and complication rate (p > 0.05) between the two groups. The number of days until first dressing change after surgery, the number of dressing changes or follow up visits in the outpatient care until complete wound healing, and the overall number of dressing changes were all statistically significantly reduced (p < 0.05). CONCLUSION: Addition-cured silicone used as a moulded dressing in full thickness skin grafts has longer durability and leads to a significant reduction of dressing changes with equal aesthetic outcome compared to an establishes silicone sheet dressing.

RESUMO

OBJECTIVE: Droopy tip may lead to functional impairment due to nasal valve insufficiency. There are several techniques available in order to correct under rotated tip, including sutures, resection and grafting. The major drawback of these standart procedures is the correction of nasal cartilage framework rather than droopy skin envelope. In this study, we demonstrated the long-term results of percutaneous rhinolift procedure which aids in the correction of cartilage framework position and droopy skin at the same time, in patients who had isolated nasal tip ptosis. METHODS: Seventeen patients with nasal tip ptosis who underwent rhinolift procedure under local anesthesia, between September 2016 and February 2017, included in the study. Nasal obstruction was evaluated by Nasal Obstruction Symptom Evaluation (NOSE) Scale and Visual Analog Scale (VAS) before the procedure, and 1st month and 3rd month after the procedure. Long-term follow-up scores were also analyzed. RESULTS: There was a significant difference between preoperative NOSE scores and 1st, 3rd month and long-term follow-up scores (p < 0.001). When we analyzed the VAS scores of patients, there was significant difference between preoperative scores and 1st month, 3rd month and long-term follow-up scores (p < 0.001). DISCUSSION: Suspension sutures have been used to hang and lift the ptotic tissues of nasal tip. In this study, we found that rhinolift procedure is an effective method for droopy nasal tip cases especially with excess skin volume who cannot undergo a major invasive surgical operation. IMPLICATIONS FOR PRACTICE: It is a conservative and cheap method which does not require general anesthesia.

RESUMO

BACKGROUND: Surgical site infection (SSI) after dermatologic surgery is associated with poor outcomes including increased recovery time, poor cosmesis, and repeat visits to doctors. Prophylactic antibiotics are prescribed to reduce these adverse outcomes. Identifying risk factors for SSI will facilitate judicious antibiotic prophylaxis. OBJECTIVE: To identify risk factors for SSI after minor dermatologic surgery. METHODS: Individual patient data from four large randomized controlled trials were combined to increase statistical power. A total of 3,819 adult patients requiring minor skin procedures at a single facility were recruited over a 10-year period. The main outcome measure was SSI. MAIN RESULTS: A total of 298 infections occurred, resulting in an overall incidence of 7.8% (95% confidence interval [CI], 5.8-9.6), although the incidence varied across the four studies (P = .042). Significant risk factors identified were age (relative risk [RR], 1.01; 95% CI, 1.001-1.020; P = .008), excisions from the upper limbs (RR, 3.03; 95% CI, 1.76-5.22; P = .007) or lower limbs (RR, 3.99; 95% CI, 1.93-8.23; P = .009), and flap/two-layer procedures (RR, 3.23; 95% CI, 1.79-5.85; P = .008). Histology of the excised lesion was not a significant independent risk factor for infection. CONCLUSIONS: This study demonstrated that patients who were older, underwent complex excisions, or had excisions on an extremity were at higher risk of developing an SSI. An awareness of such risk factors will guide evidence-based and targeted antibiotic prophylaxis.

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a dermal sarcoma often diagnosed by excision biopsy, and is often incompletely excised, with high recurrence rates. Traditional wide excision involves resection margins of 2-4 cm, often resulting in morbid procedures requiring surgical reconstruction. An alternative is conservative re-excision (CRE), which results in narrower margins and less-frequent reconstruction. The aim of this study is to assess the effectiveness of CRE in providing local control. PATIENTS AND METHODS: A retrospective review of patients treated for DFSP at a tertiary sarcoma centre over a 10-year period. RESULTS: Ninety-eight patients were analysed. Median follow-up was 53 months. Fifty-four patients had microscopically incompletely excised DFSP, and of these, 41 underwent CRE of DFSP scar. Seven (17.1%) patients required more than one CRE to achieve negative margins. The mean width of CRE was 15.4 mm. Fifty-four patients had resection of intact tumours, with 19 (35.2%) requiring surgical reconstruction. One patient (1%) developed local recurrence, and one patient (1%) distant recurrence-both of these patients had high-grade fibrosarcomatous DFSP. No patient with classical DFSP who had clear margins sustained recurrence, regardless of whether their surgery was CRE of scar or wide excision of tumour. CONCLUSIONS: CRE is a safe and acceptable alternative to traditional wide excision, with no patients developing local recurrence (LR). CRE results in low rates of surgical reconstruction, and hence lower morbidity; this is partially offset by the higher rates of inadequate excision requiring further surgery. However, the lesser rate of inadequate excision compared with rates of reconstruction makes CRE an attractive option.

RESUMO

BACKGROUND: The use of sutures remains the first choice for wound closure. However, incorrect use of a suture technique can lead to impaired healing. Many techniques are described for high-tension wounds, but not much is known about their mechanical properties. Complications of excessive tension include dehiscence, infection, and ischemic necrosis and could be prevented. This study aimed to compare forces in five techniques (single, horizontal mattress, vertical mattress, pulley, and modified pulley suture) in a standardized wound tension model. MATERIALS AND METHODS: A standardized neoprene wound model was developed on the ForceTRAP system (MediShield B.V., Delft, The Netherlands) to mimic a 5 Newton (N) wound. Five different suture techniques were each repeated 10 times by a student, resident dermatology, and dermsurgeon. The pulling force of the suture's first throw was measured with the Hook-in-Force sensor (Technical University Delft, The Netherlands). Changes in wound tension were measured by the ForceTRAP system. The ForceTRAP is a platform measuring forces from 0 to 20 N in three dimensions with an accuracy of 0.1 N. The Hook-in-Force is a force sensor measuring 0-15 N with an accuracy of 0.5 N. Maximum and mean forces were calculated for each suture technique and operator. RESULTS: Mean maximum pulling force: 5.69 N (standard deviation [SD], 0.88) single, 7.25 N (SD, 1.33) vertical mattress, 8.11 N (SD, 1.00) horizontal mattress, 3.46 N (SD, 0.61) pulley, and 4.52 N (SD, 0.67) modified pulley suture. The mean force increase on the skin (substitute) ranged between 0.80 N (pulley) and 0.96 N (vertical mattress). CONCLUSIONS: The pulley suture requires less pulling force compared with other techniques. The mechanical properties of sutures should be taken in consideration when choosing a technique to close wounds.

RESUMO

Pyoderma gangrenosum (PG) classically presents with an acute inflammatory stage, characterized by rapid evolution of painful ulcerations. The pathergy associated with PG lesions complicates disease management. Although PG is commonly treated with immunosuppression, some patients have refractory noninflammatory ulcers. In this subpopulation, there are case reports of successful surgical treatment. However, there is no consensus on optimal perioperative treatment for patients with PG undergoing surgery of any kind, PG related or otherwise. Therefore, we conducted a comprehensive literature review describing perioperative management practices and risk factors that may predict response to surgical intervention. We identified 126 cases of surgical intervention in patients with active PG; among these, only 16.7% experienced postoperative disease progression. No perioperative treatments or clinical risk factors were identified as statistically significant predictors of disease recurrence. Although limited by case series design and publication bias, this study is a valuable means of hypothesis generation for this rare condition.

RESUMO

Hidradenitis suppurativa (HS) is a chronic inflammatory disease affecting intertriginous skin areas, and it is characterized by recurrent painful episodes of inflammatory drainage. Although the pathophysiology of HS is not fully understood, recent research points to an imbalance of cytokines as a contributing factor to the associated symptoms of purulent drainage and sinus tract formation. HS lesions are often characterized by a superimposed pathogenic/commensal bacterial infection that can improve with targeted antibiotic therapy. New medical treatments have emerged in recent years, many of which specifically work against a variety of proinflammatory mediators associated with HS. These newer, specified treatment options, in conjunction with surgery and lasers, are thought to provide positive outcomes and an overall improvement in quality of life in patients with HS.
