The Use of Posterior Auricular Fascia Graft (PAFG) for Slight Dorsal Augmentation and Irregular Dorsum Coverage in Primary and Revision Rhinoplasty: A Prospective Study.

INTRODUCTION: Augmentation and coverage of irregularities of the nasal dorsum remain a challenge in rhinoplasty. Different techniques have been described in the current literature for this purpose. The aim of this study is to assess and illustrate the author experience and outcomes using the posterior auricular fascia graft (PAFG) for dorsal camouflage and augmentation in primary and revision rhinoplasty. MATERIAL AND METHODS: A prospective bicentric study was conducted, including patients with slight dorsal deficiencies and/or with dorsal irregularities following hump resection, trauma or previous rhinoplasty receiving PAFG to improve the rhinoplasty outcome. To objectively assess the graft resorption rate, MRI was performed 2 weeks and 18 months after surgery. To investigate patient satisfaction, the preoperative and 1-year postoperative scores obtained using the rhinoplasty outcomes evaluation (ROE) scale were compared. The scores following a normal distribution obtained for each patient were compared using a paired t-test. RESULTS: Forty-five patients were enroled in this study. Average follow-up duration was 35.4 months. Patients' age ranged from 17 to 57 years. No cases of infection or major graft resorption were observed. No postoperative scars were visible at the donor site. All patients were satisfied after surgery, and a statistically significant difference between pre- and postoperative scores (p<0.0001) was observed. CONCLUSION: This study showed that PAFG is a reliable technique for dorsal camouflage and slight augmentation in primary and revision rhinoplasty. The procedure is safe, easy and quick and only requires a small learning curve. LEVEL OF EVIDENCE II: This journal requires that authors assign a level of evidence to each article.

Assessment of Patient Satisfaction Using a New Augmented Reality Simulation Software for Breast Augmentation: A Prospective Study.

Background: Breast augmentation is one of the most frequently performed plastic surgery procedures. Providing patients with realistic 3D simulations of breast augmentation outcomes is becoming increasingly common. Until recently, such programs were expensive and required significant equipment, training, and office space. New simple user-friendly programs have been developed, but to date there remains a paucity of objective evidence comparing these 3D simulations with post-operative outcomes. The aim of this study is to assess the aesthetic similarity between a pre-operative 3D simulation generated using Arbrea breast simulation software and real post-operative outcomes, with a focus on patient satisfaction. Methods: The authors conducted a prospective study of patients requiring breast augmentation. Patients were asked to assess how realistic the simulation was compared to the one-year post-operative result using the authors' grading scale for breast augmentation simulation assessment. Patient satisfaction with the simulations was assessed using a satisfaction visual analogue scale (VAS) ranging from 0 (not at all satisfied) to 10 (very satisfied). Patient satisfaction with the surgical outcome was assessed using the BREAST-Q Augmentation Module. Results: All patients were satisfied with the simulations and with the attained breast volume, with a mean VAS score of 8.2 ± 1.2. The mean simulation time took 90 s on average. The differences between the pre-operative and one-year post-operative values of the three BREAST-Q assessments were found to be statistically significant (p < 0.001). Conclusions: Three-dimensional simulation is becoming increasingly common in pre-operative planning for breast augmentation. The present study aimed to assess the degree of similarity of three-dimensional simulations generated using Arbrea Breast Software and found that the use of the software provided a very satisfying representation for patients undergoing breast augmentation. However, we recommend informing patients that only the volume simulation is extremely accurate. On the other hand, it is necessary to not guarantee an absolute correspondence regarding the breast shape between the simulation and the post-operative result.

Breast implant associated anaplastic large cell lymphoma (BIA-ALCL): a challenging cytological diagnosis with hybrid PET/MRI staging and follow-up.

We report a case of a 55-year-old woman with left breast cosmetic augmentation performed 5 years earlier, showing at ultrasound a left small amount of peri-implant effusion suspicious for an anaplastic large cell lymphoma localization. The final diagnosis was obtained by cytology using a small amount of fluid (6 ml). Subsequently, hybrid 18F-FDG PET/MRI was used for pre-operative staging and follow-up. An appropriate management of BIA-ALCL could be obtained even in cases of a small amount of peri-implant effusion, using a comprehensive approach of clinical and imaging evaluation, including PET/MRI as useful and innovative staging imaging technique.

Chronic hand eczema: is IL-36α helpful in diagnosis and classification?

BACKGROUND: Chronic hand eczema (CHE) is not a homogenous disease, necessitating complex differential diagnostics. Interleukin (IL) -1 family members are significantly up-regulated in ACD and psoriasis patients skin. METHODS: The present study aims to deepen the knowledge about clinical assessment and characterization of patients affected by chronic hand dermatitis (CHD) as well as to investigate the role of possible biomarkers which may help in the diagnostic process. An observational case-control study was performed enrolling 30 CHD patients and 20 healthy controls. Each patient underwent detailed medical history, clinical examination, epicutaneous patch test, and lesional skin biopsies for histological and immunohistochemical analysis. RESULTS: Patient history, clinical examination and patch testing led us to a final CHD characterization in only 8/30 subjects (26.7%). In the remaining subjects, clinical and histological features suggested a diagnosis of psoriasis in 9/22 (30%) and idiopathic chronic hand eczema (CHE) in 13/22 (43.3%). Trying to find a possible marker for the latter dermatosis, we analyzed IL-1 family in all the recruited subjects. IL-1 members were increased in all conditions, but IL-36α was the only analyzed cytokine able to characterize patients who end up with a diagnosis of idiopathic CHE. CONCLUSIONS: In conclusion, we can assess that medical history and patch testing remain essential investigations in CHD patients even if not always sufficient to perform a final diagnosis. Moreover, IL-1 members are probably involved in CHE skin inflammation, with IL-36α being a possible future biomarker which might help in the complex diagnostic process of CHE.

IL-33 is regulated by TNF-α in normal and psoriatic skin.

Interleukin-33 (IL-33) is the most recently discovered IL-1 family member. Considered an endogenous "alarmin" released by necrotic cells in response to tissue injury or damage, IL-33 is constitutively expressed in tissues exposed to the environment, where endothelial and epithelial cells constitute its major sources. Several findings reported that pro-inflammatory stimuli, such as IFN-γ and TNF-α, as well as IL-17, can induce IL-33 expression in normal human epidermal keratinocytes. In the present study, we deeply investigated the relation between IL-33 and TNF-α, by employing the whole skin as study model. TNF-α dose- and time-dependently induced IL-33 gene expression in ex vivo healthy skin organ culture. Similarly, TNF-α significantly increased IL-33 mRNA expression in normal human epidermal sheets. Moreover, IL-33 was enhanced in psoriatic skin and anti-TNF-α therapy was able to significantly reduce it. The biology of IL-33 is gaining in complexity, and this molecule is now known to have additional roles beyond its original description. In particular, we can assess that IL-33 is regulated by TNF-α in normal and psoriatic skin.

Giant breast tumors in a patient with Beckwith-Wiedemann syndrome.

Beckwith-Wiedemann syndrome (BWS) is an overgrowth disorder with increased risk of embryonal tumors, such as Wilms tumor, hepatoblastoma, neuroblastoma, and rhabdomyosarcoma. We report on a patient with BWS that developed a giant fibroadenoma of the breast that was surgically removed. The tumor relapsed 8 months after the surgery and the patient underwent partial mastectomy. Although the patient presented several clinical features of BWS, a molecular diagnosis was not achieved despite extensive molecular investigations on both blood and tumor tissue. A SNP array revealed a de novo 7p22.1 loss in both blood and breast tumor involving the mismatch repair gene PMS2 gene that may be potentially associated with the breast tumor. In conclusion, it remains unclear whether BWS patients have an increased risk of breast lesions or a yet unknown molecular defect is responsible for the rare occurrence of this tumor in BWS.

Microvascular free-flap transfer for head and neck reconstruction in elderly patients.

BACKGROUND: With the increase in life expectancy, the incidence of head and neck cancer has grown in the elderly population. Free tissue transfer has become the first choice, among all the reconstructive techniques, in these cases. The safety and success of micro vascular transfer have been well documented in the general population, but its positive results achieved in elderly patients have received less attention. METHODS: We retrospectively studied 28 patients over the age of 60 years. The aim of this paper was to study the success rate of free tissue transfer and investigate the complication incidence in this patient population. RESULTS: Twenty-eight free flaps were performed to reconstruct medium to large cervico-facial surgical defects in six years. No difference was noted between success and complication rates observed between general and elderly population. CONCLUSION: This study indicates that free-flap technique for head and neck reconstruction could be considered a safe option in elderly patients when a good pre-operative general status is present.

Versatility of the posterior auricular flap in partial ear reconstruction.

BACKGROUND: The posterior auricular flap alone has always been popular because of its prompt availability, its rich vascularity, and the ease of closing the donor-site defect primarily. METHODS: Fifty-seven patients with partial ear defects covered with posterior auricular flaps during the period between 2002 and 2007 were reviewed. In the authors' series, posterior auricular flaps were harvested based on a simple random vascularization and tailored to reach almost any defect of the ear by a simplified and standardized approach. RESULTS: The authors propose a simple nomenclature after grouping the flaps according to skin paddle type, pedicle type, pedicle base, flap transfer method, and flap movement; they present a standardized algorithm with which to choose the flap design for a given defect from this group. CONCLUSIONS: The authors contribute three new flap designs to enhance the versatility of the posterior auricular flap. These are the superiorly and inferiorly based twisted island flaps and the posterior auricular propeller flap.

Laser lipolysis: flaccidity under control.

An innovative liposuction technique using a laser device is presented. It is a precise method, less traumatic than the conventional one. The interaction between the laser and the adipocyte causes lipolysis with reduced bleeding and its effect on collagen tone promotes collagen retraction and skin shrinkage. The results of the use of laser lipolysis on flaccid areas or in areas with the potential for flaccidity are shown. The resulting skin retraction and the pathologic anatomy confirm these claims.
