RESUMEN

BACKGROUND: To assess the impact of propranolol as the first-line treatment of infantile hemangioma (IH) on the need for surgery in the management of IH. METHODS: Retrospective study of 420 patients, with IH, referred to our multidisciplinary center between January 2005 and August 2014. Clinical data including sex, age at first consultation and at treatment initiation, location, size, number, aspect, and complication of IH, as well as the type of treatment were collected. Statistical analyses were conducted considering each patient and each tumor independently. RESULTS: A total of 625 IH(420 patients (P))were reviewed, 113 patients had more than one IH (26.91%). Median age at first consultation was 7 months old. Overall, 243 patients were treated (57.86%) using either surgery (n=128 P/141 IH), propranolol (n=79 P/89 IH), corticosteroids (n=51 P/56 IH), and/or laser (n=34 P /36 IH). Propranolol was effective in all but 2 infants with IH. Seven patients (n=7/79 P; 8.86%) initially treated with propranolol, still required surgery, in contrast to 18 patients (n=18/51 P; 35.29%) initially treated with corticosteroids, and 103 patients (n=103/290 P; 35.51%) with no medical treatment. Since the availability of propranolol, patients were less likely to undergo surgery (48 P versus 80 P; P-Value < 0.001). This demonstrated that the use of propranolol reduced the need for surgery (P-Value < 0.001 with an OR of 0.177: CI 95% 0.079-0.396). CONCLUSION: Propranolol has dramatically reduced the need for surgery, regarding indications and number of patients. Surgical correction remains important for sequelae management, non-responders or strawberry-like IH.

RESUMEN

BACKGROUND: There is a renewed interest for prepectoral reconstruction. We aimed to describe the feasibility and the early complications associated with immediate one-stage direct-to-implant (DTI) reconstruction using prepectoral anatomical polyurethane (PU) foam-coated implants alone, for women with breast cancer or mutation carriers undergoing risk-reducing surgery. METHODS: We performed a single-center, retrospective review of 50 patients (mean age of 49 years), who underwent skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) and immediate prepectoral PU implant-based reconstruction. All procedures were performed by the same senior operator, from July 2018 to March 2020. RESULTS: A total of 64 mastectomies (25 SSMs and 39 NSMs) with one-stage prepectoral PU foam-coated implant reconstruction were performed. Out of 50 patients, 6 required surgical revision within 30 days, because of hematoma (2), wound dehiscence (2) infection (1), and full thickness nipple-areolar complex (NAC) necrosis (1). Four patients developed a cutaneous rash with spontaneous resolution. Statistical analysis showed a significant influence of hypothyroidism and previous radiotherapy on the risk of complications. The association with prior radiotherapy (pRT) was not significant using binary logistic regression. When excluding oncological reasons and patient's wish for NAC excision, our decision to perform an NSM was influenced by breast cup size, preoperative measurements, and breast weight. CONCLUSIONS: Early experience with immediate prepectoral DTI reconstruction with PU-covered implants alone suggests that it is a reliable procedure. Prior breast irradiation does not increase postoperative complication rates in our series. NAC preservation was decided according to preoperative lower breast measurements.

RESUMEN

Reconstruction of large full-thickness scalp defects with exposed cranial bone or dura are usually performed with free flaps. However, certain medical conditions in fragile patients may contraindicate this type of surgery. In those circumstances, Dermal Regeneration Templates (DRTs) can provide an alternative solution to flap surgery. We here report the case of a 79-year old woman presenting with a large cranial defect and exposed dura mater after developing postsurgical Pyoderma Gangrenosum and subsequent free flap failure. A one-stage salvage reconstruction was successfully performed with MATRIDERMⓇ (MedSkin Solutions Dr. Suwelack AG, Germany) and a split-thickness skin graft (STSG) with a Vacuum-Assisted Closure (VAC) dressing.

RESUMEN

Obstructive sleep apnea (OSA) results from a combination of several factors leading to the obstruction of the upper respiratory tract (URT). OSA represents a systemic pathophysiological entity and leads to many comorbidities such as hypertension, coronary ischemia, and stroke. Patients with this pathophysiological entity experience also an increased risk of postoperative complications. Obesity is certainly the main cause of developing OSA. However, many other predisposing factors influence the genesis of obstructive apnea. It is important to understand the complexity of the interactions between predisposing factors to understand the relationship between weight loss following obesity surgery and the improvement in the severity of OSA. In this narrative review, we expose the seven major categories of predisposing factors that interact to generate obstructive apneas in patients, namely the anatomic abnormalities of the URT, the mechanical and the metabolic responses of the upper airway musculature, the loop gain, the arousal threshold, and the hormonal abnormalities. The genesis of apnea is the result of a complex dynamic interaction between the anatomical risk factors and the compensatory neuromuscular reflexes. All of these points are integrally part of the perioperative care of the obese patients. Finally, we will discuss different options for weight reduction.

RESUMEN

BACKGROUND: In the field of vascularized composite tissue allotransplantation, the surgical design of facial subunit grafts is an evolving concept. The purpose of the present article is to study the possibility of dividing the historical nose and lip face transplant into several morphologic and functional subunit grafts, depending on their respective supply. METHODS: This study was conducted in 20 adult cadavers. The facial artery and its branches were dissected bilaterally in 16 fresh and four embalmed heads. Nasolabial perfusion was assessed by selective injection of methylene blue and eosin (n = 2) or India ink (n = 2) in the superior labial and distal facial arteries. Dynamic perfusion through the distal facial artery was illustrated by fluoroscopy (n = 3). Three nose-upper lip grafts were harvested and injected with barium sulfate for microangiography computed tomographic analysis. Finally, three isolated nasal and bilabial grafts were procured and their vascular patency assessed by fluoroscopy. RESULTS: The distal facial artery can perfuse the entire nose, septum, and upper lip, without any contribution of the superior labial artery. A dense anastomotic network indeed exists between the respective distal rami of both vessels. Furthermore, the exclusion of the superior labial artery from the harvested nasal subunit allowed safe bilabial subunit procurement, from the same specimen. CONCLUSIONS: The authors' results demonstrate the feasibility of harvesting nasal and labial subunits, in an isolated or a combined manner. These results can find applications in subunit autologous replantation, allotransplantation, allogenic face partial retransplantation, and the emerging field of vascularized composite tissue engineering.

RESUMEN

In the field of experimental facial vascularized composite tissue allotransplantation, a human auricular subunit model, pedicled on both superficial temporal and posterior auricular arteries, was described. Clinical cases of extensive auricular replantation, however, suggested that a single artery could perfuse the entire flap. In this study, variants of this single-pedicle approach have been studied, aiming to develop a more versatile replantation technique, in which the question of venous drainage has also been addressed. For arterial perfusion study, the authors harvested 11 auricular grafts, either on a single superficial temporal artery pedicle (n = 3) or a double superficial temporal and posterior auricular artery pedicle (n = 8). The authors then proceeded to selective barium injections, in the superficial temporal, posterior auricular, or both superficial temporal and posterior auricular arteries. Arteriograms were acquired with a micro-computed tomographic scan and analyzed on three-dimensionally reconstructed images. Venous drainage was investigated in eight hemifaces, carefully dissected after latex injection. Observations showed a homogenous perfusion of the whole auricle in all arterial graft variants. Venous drainage was highly variable, with either a dominant superficial temporal vein (37.5 percent), dominant posterior auricular vein (12.5 percent), or co-dominant trunks (50 percent). The authors demonstrated that auricular subunit vascularized composite tissue allotransplantation can be performed on a single artery, relying on the dynamic intraauricular anastomoses between superficial temporal artery and posterior auricular branches. Potentially, this vascular versatility is prone to simplify the subunit harvest and allows various strategies for pedicle selection. Venous drainage, however, remains inconstant and thus the major issue when considering auricular transplantation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.
