RESUMO

Cutaneous squamous cell carcinoma is a prevalent malignancy with a rising incidence and a notably high mutational load. Exploring the genetic nuances of cSCC and investigating molecular approaches stands as a potential avenue for improving outcomes in high-risk patients. This retrospective case-control study involved two cohorts, one of 14 patients (the "discovery cohort") and the other of 12 patients (the "validation cohort"), with cSCC located in the head/neck anatomical region and diagnosed at the pT2 stage. Overall, cases developed early local relapses of the disease, whereas controls never relapsed during the entire follow-up period. A next-generation sequencing (NGS) approach conducted on histological samples revealed that TP53 and CDKN2A were the most frequently mutated genes in our series. No specific mutations were identified as potential prognostic or therapeutic targets. Controls exhibited a tendency toward a higher mutational rate compared to cases. It is possible that an increased number of mutations could prompt the cSCC to expose more antigens, becoming more immunogenic and facilitating recognition by the immune system. This could enhance and sustain the immunological response, potentially preventing future recurrences.

RESUMO

Background: Direct-to-implant (DTI) immediate breast reconstruction has proven to be an oncologically safe technique and linked to better overall results. The introduction of new surgical techniques has prompted us to develop an acellular dermal matrix fixation technique that reduces the rate of complications and implant loss. Methods: We retrospectively analyzed data from patients who underwent DTI prepectoral breast reconstruction with two different techniques of acellular dermal matrix fixation to the chest wall. Descriptive statistics were reported using frequencies and percentages for categorical variables, and means and SDs for continuous variables. Pearson chi-square test was used to compare differences in categorical variables. Univariable and multivariable logistic regression models were fitted to investigate the predictors of complications. Results: From October 2019 to March 2023, 90 DTI breast reconstructions were performed, 43 using the standard technique and 47 using the new technique. The new technique demonstrated a significant reduction of major complications (P = 0.010), namely seroma (13.9% versus 2.3%), skin necrosis (9.3% versus 2.3%), implant loss (7% versus 0%), wound dehiscence (9.3% versus 0%), and infection (4.7% versus 0%). Compared with the standard technique, the new one reduced the risk of complications by 76% (OR 0.24; 95% confidence interval 0.09-0.68; P = 0.007) and 73% (aOR 0.27; 95% confidence interval 0.08-0.92; P = 0.037), at univariable and multivariable regression models. No other significant predictor of complications was identified. Conclusions: The procedure performed with the proposed modality proved to be advantageous. Careful fixation of the prosthetic implant and the placement of two drains, were the keys to a drastic reduction in complications.

RESUMO

BACKGROUND: Tumescent local anesthesia (TLA) involves the infusion of a saline solution containing lidocaine and epinephrine into tissues to achieve localized anesthesia and vasoconstriction. While the use of TLA in sub-glandular augmentation mammoplasty has been documented, we present a modified TLA approach for primary sub-muscular breast augmentation in transgender patients based on our experience over the past years. METHODS: Between the years 2014 and 2021, we performed primary sub-muscular breast augmentation on 20 transgender patients under TLA and conscious sedation. The tumescent solution consisted of 25 mL of 2% lidocaine, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) in 1000 mL of 0.9% saline solution. Initially, the solution was infiltrated between the pectoral fascia and the mammary gland, and subsequently, during the surgery, under the pectoralis major muscle. RESULTS: The average volume of tumescent solution infiltrated during TLA was 740 mL per breast. There were no reports of adrenaline or lidocaine toxicity, and no cases required a conversion to general anesthesia. Patients experienced no pain or discomfort during the preoperative infiltration or surgical procedure. Reoperations due to short-term complications never occurred. We observed a major complication rate of 5%, represented by 1 hematoma. Long-term complications comprised one case of implant dislocation and one occurrence of dystrophic scar formation. No cases of capsular contracture needing reoperation, asymmetry, and implant rupture occurred. In total, one individual (5%) requested larger implants. Follow-up time ranged from 30 days to 1 years. CONCLUSIONS: Overall, augmentation mammaplasty is a valuable choice for transgender women aiming to enhance their feminine characteristics and alleviate gender dysphoria. It is imperative for patients to conduct thorough research, grasp the potential pros and cons, and consult experienced healthcare professionals in transgender care. Additionally, tumescent local anesthesia (TLA) has proven to be a safe and efficient method for sub-muscular breast augmentation, providing effective pain control with minimal postoperative complications, resulting in high patient satisfaction.

RESUMO

Background: Scalp-associated cutaneous squamous cell carcinoma (cSCC) presents formidable treatment challenges, especially when it leads to full-thickness defects involving bone. Aggressive or recurring cases often demand a multidisciplinary approach. Leveraging our surgical experience and a literature review, we introduce a therapeutic algorithm to guide the selection of reconstruction methods, particularly for locally advanced lesions, furthermore showing the synergy between surgery and other therapies for comprehensive, multidisciplinary disease management. Methods: Our algorithm stems from a retrospective analysis of 202 patients undergoing scalp cSCC resection and reconstruction over a 7-year period, encompassing 243 malignancies. After rigorous risk assessment and documentation of surgical procedures, reconstruction methods were therefore related to malignancy extent, depth, and individual clinical status. Results: The documented reconstructions included 76 primary closures, 115 skin grafts, 7 dermal substitute reconstructions, 33 local flaps, 1 locoregional flap, and 1 microsurgical free flap. Patients unsuitable for surgery received radiotherapy or immunotherapy after histological confirmation. Precise analysis of tumor characteristics in terms of infiltration extent and depth guided the selection of appropriate reconstruction and treatment strategies Combining these insights with an extensive literature review enabled us to formulate our algorithm for managing scalp cSCCs. Conclusions: Effectively addressing scalp cSCC, especially in locally advanced or recurrent cases, demands a systematic approach integrating surgery, radiotherapy, and immunotherapy. Our multidisciplinary team's decision-making algorithm improved patient outcomes by offering a broader spectrum of therapeutic options that can synergistically achieve optimal results.

RESUMO

Squamous cell carcinomas of the nasal vestibule are an extremely rare neoplastic disease. Although brachytherapy is gaining popularity for primary treatment, surgery remains the best option in case of recurrences. The aim of this paper is to outline our treatment experience of local recurrence of SCCNVs over the past 22 years. We retrospectively reviewed the clinical data of the patients who underwent surgical treatment for local recurrence of SCCNV: data regarding age, sex, primary tumor treatment, recurrence location and time of appearance, surgical resection, type of reconstruction, postoperative complication, surgical revision, and re-recurrence rate were analyzed. Twenty patients were included in the study. The median period for recurrence appearance was 17 months, and the prevalent location of recurrence was the nasal alae. Prevalent reconstructive procedures were the nasolabial flap and paramedian forehead flap. No postoperative complications were observed, and one case of re-recurrence was detected at 12-months of follow-up. Based on our experience, salvage surgical procedures for SCCNV recurrences must be individualized and carefully planned, taking into account the peculiar pattern of tumor spread and the presence of scar and heavily radiotherapy damaged tissue from previous treatment; delayed reconstruction should be considered for all the cases with skeletal involvement.

RESUMO

BACKGROUND: Abdominoplasty is a common surgical procedure performed under general anesthesia, and although the use of TLA combined with subdural anesthesia has never been reported in abdominoplasty, it offers several benefits such as safe and effective local anesthesia and vasoconstriction. We outline our experience with the TLA technique for primary abdominoplasty over the last 7 years. METHODS: From 2014 to 2021, TLA and subdural anesthesia have been used in primary abdominoplasty surgeries for 106 patients. The TLA solution consisted of 25 mL of 2% lidocaine, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) diluted in 1000 mL of 0.9% saline solution. The solution was then injected with a 2-mm cannula into the subcutaneous adipose tissue in the suprafascial plane. The subdural anesthesia was performed at intervertebral level L1-L2 using Ropivacaine 15/18 mg in 4 ml. RESULTS: Patients aged from 32 to 75 years. The amount of tumescent solution infiltrated ranged between 500 and 1000 mL. Mean surgery time was 70 minutes, and recovery room time averaged at 240 minutes. Major complications related to the surgery were observed in 12.26% of patients, including eight hematomas and five seromas. Two patients experienced wound dehiscence, and no dystrophic scar formation was observed. Eventually, there was no need for a conversion to general anesthesia. CONCLUSIONS: Tumescent local anesthesia combined with subdural anesthesia is a highly effective and safe method for performing abdominoplasty. This technique has proven to be an excellent choice for primary abdominoplasty, providing significant benefits to patients and surgeons alike due to its safe administration, precise pain management during and after surgery, and minimal postoperative side effects.

RESUMO

BACKGROUND: Body contouring surgery is increasingly requested by patients, both for aesthetic and post-bariatric purposes. There has also been a rapid increase in demand for noninvasive aesthetic treatments. While brachioplasty is burdened by numerous complications and unsatisfactory scars, and conventional liposuction is unsuitable for all patients, nonsurgical arm remodeling performed with radiofrequency-assisted liposuction (RFAL) allows to effectively treat most of patients, regardless of the amount of fat and ptosis of the skin and avoiding surgical excision. METHODS: A prospective study was conducted on 120 consecutive patients who presented to the author's private clinic and required upper arm remodeling surgery for aesthetic purposes or after weight loss. Patients were classified according to the modified classification of El Khatib and Teimourian. Pre- and posttreatment upper arm circumferences were taken after 6 months of follow-up to assess the degree of skin retraction obtained by treating the arm with RFAL. A satisfaction questionnaire regarding the appearance of the arms (Body-Q upper arm satisfaction) was administered to all patients before surgery and after 6 months of follow-up. RESULTS: All patients were effectively treated with RFAL, and no cases required conversion to brachioplasty. The average reduction in arm circumference was 3.75 cm at 6 months follow-up, and patients' satisfaction increased from 35 to 87% posttreatment. CONCLUSIONS: Radio frequency is a valid tool to treat most patients with upper limbs skin laxity, with significant aesthetic results and a high degree of patient satisfaction, regardless of the degree of skin ptosis and lipodystrophy of the arm.

RESUMO

BACKGROUND: Tumescent local anesthesia (TLA) describes the practice of injecting a very dilute solution of local anesthetic combined with epinephrine and sodium bicarbonate into the tissue until it becomes firm and tense to obtain local anesthesia and vasoconstriction. The use of TLA in augmentation intramuscular gluteoplasty has never been described for implants positioning. Advantages of the TLA technique include a reduction in blood loss through epinephrine-induced vasoconstriction and hydrostatic compression from the tumescent effect. We describe TLA technique for primary intramuscular gluteal augmentation, reporting our experience during the last 5 years. METHODS: From 2017 to 2021, 20 patients underwent bilateral primary gluteal augmentation under TLA and conscious sedation. The tumescent solution was prepared with 25 mL of 2% lidocaine, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) in 1000 mL of 0.9% saline solution. The solution was infiltrated with a cannula inside the gluteus maximus muscle intra-operatively. RESULTS: The mean age of the patients was 39, 15 years. The average amount of tumescent solution infiltrated was 240 mL per gluteus. Operating time was 1 h and 40 min, and recovery room time averaged 240 min. Major surgery-related complications were found in 15% of patients (2 hematomas and 1 seroma) and minor complications were described in a total of 8 patients (4 wound dehiscence and 1 dystrophic scar formation). No signs of adrenaline nor lidocaine toxicity were reported and conversion to general anesthesia was never required. CONCLUSIONS: The tumescent local anesthesia technique represents a safe and efficacious technique for performing gluteal augmentation surgery with an intramuscular implant positioning. The advantages of this technique are safety, reasonable pain control during and after surgery and a low incidence of postoperative side effects due to general anesthesia avoidance.

RESUMO

Immediate implant-based breast reconstruction in patients with large and ptotic breasts may be challenging due to skin redundancy. The use of a reduction mammoplasty pattern for the mastectomy skin excision has proven to be a reliable option for these patients as it allows for a better shape, projection, and symmetrization. This approach has been described in the literature for both one- and two-stage reconstruction with either sub- or pre-pectoral reconstruction with an acellular dermal matrix (ADM) or non-biological mesh. One-stage immediate breast reconstructions have a positive significant impact on patients' psychosocial well-being and quality of life. The purpose of this paper is to describe an institutional algorithm that allows one to perform one-stage implant-based breast reconstructions in patients with large and ptotic breasts.
