Eccrine porocarcinoma: case report and review of the literature.

Eccrine porocarcinoma is a rare skin cancer that originates from the acrosyringium of eccrine sweat glands. From the clinical point of view the differential diagnosis with other skin cancers such as basal cell carcinoma and squamous cell carcinoma it is often impossible, only the histopathologic features can lead to the definitive diagnosis. Eccrine porocarcinoma can arise from a previous poroma or de novo, it may recur after surgical excision and cause lymph node and visceral metastasis. There are no international guidelines for treatment or follow-up of patients. The aim of this work was to present a rare case of eccrine porocarcinoma of the scalp successfully treated in our clinic and to extrapolate from the international literature the main clinical and histopathological features of eccrine porocarcinoma and the various experiences regarding the types of treatment.

Single center evidence for the treatment of basal cell carcinoma of the head and neck.

AIM: Basal Cell Carcinoma (BCC) alone accounts for 80% of cases of non-melanoma skin cancer (NMSC), which characteristically develops on sun-exposed skin. Indeed the most common site of BCC is the head and neck region (80%). The purpose of this study to review the experience of our center with BCC in the head and neck region to report the sites of occurrence and treatment. MATERIALS AND METHOD: We retrospectively reviewed 77 patients with BCC of the head and neck, who revived surgical treatment within our plastic surgery division. Basic demographic data, cancer site and size, surgical treatment and histological data were collected. The mean follow-up period was 12 months. RESULTS: The study population included 37 males and 40 females, with a mean age of 74.12 years. The nasal unit was the main site of BCC (31.82%), followed by the periorbital (13.64%) and cervical (12.5%) units. Primary closure was the main surgical procedure performed (72.5%), followed by local flap (26.1%) and full-thickness skin grafts (1.4%). The safety resection margin ranged from 4.5 to 9 mm, with a 98.7% complete removal rate. Neither recurrence nor any newly-developed lesions were reported during follow-up in any patient. DISCUSSION: Our work reflects the shift in the incidence of BCC, which now seems to be more frequent in females. Furthermore, our data strengthens the association between UVR exposure and BCC, confirms its predilection to occur on the nasal unit and validates surgical excision as the gold standard treatment for skin cancer.

Breast reconstruction with breast implants.

BACKGROUND: Breast cancer is the most common noncutaneous malignancy among women worldwide. After a breast cancer removal procedure, women are asked to decide about breast reconstruction, mainly to improve their life quality, and they can choose from among many options. Broadly, there are two different types of breast reconstruction procedures: prosthetic implant-based reconstruction and autologous tissue-based reconstruction. METHODS: Implant-breast reconstruction is a minimally invasive procedure compared with autologous breast reconstruction. It is associated with fewer short- and long-term complications. RESULTS: The ideal candidates for implant-based reconstruction are patients with non-redundant soft tissue coverage, who desire a moderate sized non-ptotic breast and have not been previously irradiated. CONCLUSION: The state of the art for implant-breast reconstruction is briefly described in this article.

A three-year experience with medial-pedicle-based breast reduction for different mammary hypertrophy.

BACKGROUND AND AIM: The aim of breast reduction is to reduce excessive breast volume, ensuring an adequate vascular supply and sensitivity of the nipple-areola complex, as well as to produce an aesthetically pleasing final shape. The authors report on their experience with medial-pedicle-based breast reduction combined with both vertical and inverted-T skin resection patterns for different types of breast hypertrophy. METHODS: From January 2012 to June 2015, 27 female patients (mean age: 49 years) underwent reduction mammoplasty with the medial pedicle technique. The choices of medial pedicle base widths were: 6 cm for low-grade mammary hypertrophy (350-500 gr per breast), 6-8 cm for medium-grade hypertrophy (500-1000 gr per breast), or 8-10 cm for severe mammary hypertrophy (>1000 gr per breast). The authors chose the model of vertical skin resection for low-grade breast hypertrophy. The vertical model was used for medium-grade breast hypertrophy, and Wise skin resection was chosen on a case-by-case basis; only the Wise model was applied to severe breast hypertrophy.  Results: The mean weight of breast excised was 540 g on the left (range, 207 to 1160 g) and 564.8 g on the right (range, 215 to 1150 g). The complications were minor and self-limiting. All patients reported relief of neck pain, back pain, and bra strap indentations after 6 months of follow-up. CONCLUSIONS: Breast reduction surgery must address both functional and aesthetic issue by restoring an aesthetically pleasing shape to ptotic or hypertrophic breasts, repositioning the NAC in a physiological position. Various breast reduction techniques have been attempted to combine the safety of the pedicle with aesthetic and functional results. Surgeons should tailor the best technique to each patient. We found that medial-pedicle-based reduction mammoplasty is effective and reliable because it can be applied to a wide range of breast hypertrophy, with reproducible breast weight reduction and results that are aesthetically satisfactory for both patients and surgeons.

Surgical therapy of cutaneous squamous cell carcinoma: our experience.

INTRODUCTION: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer, with an excellent prognosis after surgical removal. However, nodal metastasis are present in about 5% of cases and the death rate is about 2%. PRESENTATION OF CASE: The aim of this study is to report our experience about the surgical treatment of cSCC at the Cutaneous, Regenerative, Mininvasive and Plastic Surgery Unit, University of Parma, Italy, between January 2014 and February 2016. We statistically analyzed the group of patients regarding the average age, gender, localization and size of the lesions. The surgical margins of the excisions are studied and we report the results obtained after a follow up of 3 to 25 months. DISCUSSION: Between January 2014 and February 2016 in our Cutaneous, Regenerative, Mininvasive and Plastic Surgery Unit, we removed 36 squamous cell carcinomas, including 11 cSCCs in situ. The average annual incidence of squamous cell carcinoma in northeast of Italy is about 28,9  cases per 100,000 individuals.The number of cSCCs that we removed is lower than the Italian average. In our opinion, this is due to an increase in the early diagnosis of precancerous lesions and their medical or surgical treatment. This reduces the incidence of squamous cell carcinomas developing from precancerous lesions. CONCLUSION: The excision of cutaneous squamous cell carcinoma should be undertaken with a safety margin of at least 0.9 mm to minimize recurrence and metastasis.

Nose defects reconstruction with the Zitelli bilobed flap.

The skin cancers of the head and neck district are localized mostly on the nose, which, by being in the center of the mid-face, has an important aesthetic role. Therefore, many reconstructive techniques have been studied; among them regional skin flaps appeared the most suitable since they guaranteed the oncological radicality as well as a good aesthetic outcome. In this paper, we present our experience with the use of the Zitelli bilobed flap, which is defined as a double transposition flap for the reconstruction of the nose defects. From 2008 to 2012, we have treated 86 patients (56 men and 30 women, aged between 47 and 83 years) for skin cancer of the nose (72% basal-cell carcinoma, 28% squamous cell carcinoma); for all patients, the nose defects' reconstruction was performed by means of the modified Zitelli bilobed flap. The results were evaluated by short- and long-term follow-up; no infections or major complication were reported, while high preservation of the patient's facial characteristics and normal functions of the nose were observed. In 12 cases, little distortions of the alar rim were recorded although these patients still evaluated the cosmetic outcome as good. In our experience, the Zitelli bilobed flap remains a robust and reliable tool for the reconstruction of the nose defects, since it preserves its function, while ensuring a good aesthetic result.

Laser Doppler Flowmetry and Transcutaneous Oximetry in Chronic Skin Ulcers: A Comparative Evaluation.

INTRODUCTION/OBJECTIVE: Laser Doppler Flowmetry (LDF) and transcutaneous oximetry (TcpO2) are established methods for investigating cutaneous perfusion. To date, no study previously performed has compared data obtained from these 2 methodologies in cases of chronic cutaneous ulcers. MATERIALS AND METHODS: Laser Doppler Flowmetry and TcpO2 were performed in 25 consecutive outpatients with chronic lower limb ulcers (group A, experimental; 9 women and 16 men; mean age 67 years [range, 52-81 years]) and 25 age- and sex-matched healthy control subjects (group B, control) enrolled for the study. Ulcer aetiologies included 12 peripheral arterial occlusive disease, 9 chronic venous insufficiencies, and 4 pressure ulcers. Data were analyzed with Shapiro-Wilk and Wilcoxon-Mann-Whitney tests. RESULTS: A statistically significant difference (P < .05) was found between LDF values of the 2 groups. No statistically significant differences were found between the 2 groups regarding the TcpO2 measurements. CONCLUSION: The data confirmed the soundness of LDF while investigating local perfusion in patients with chronic cutaneous ulcers. The same diagnostic accuracy was not obtained by means of TcpO2.

Reduction mammoplasty techniques in post-bariatric patients: our experience.

BACKGROUND AND AIM OF THE WORK: Excessive body weight represents a huge problem affecting a wide part of world population, causing significant physical and psychological consequences. To solve their obesity-related problems, patients should begin a bariatric treatment to lose an adequate percentage of their body mass and therefore, they should be subjected to body contouring surgery. In this article we describe our experience in applying breast remodeling techniques to post-bariatric patients. METHODS: We did a retrospective study on our post-bariatric patients subjected to breast reduction and/or mastopexy during a five-years period, considering breast features, kind of surgery performed, aesthetic and psychological outcomes and postoperative complications. RESULTS: Thirty-six post-bariatric patients underwent breast surgery in our unit between 2010 and 2015; their average age was 43 years. The follow up period ranged from 6 months to 4 years and an half. The most frequent surgical techniques performed were Thorek and inferior pedicle breast reduction. The prevalent complications observed were surgical wound delayed healing and nipple-areolar complex (NAC) partial or complete necrosis as immediate ones and unfavorable scarring as delayed ones. CONCLUSIONS: Breast reshaping after a massive loss of weight should be forerun by an accurate analysis of breast volume, shape and ptosis degree, in order to obtain optimal results both for the surgeon and the patient.

Procedure, applications, and outcomes of autologous fat grafting.

OBJECTIVE: To systematically review the procedure, applications, and outcomes of autologous fat grafting, a promising technique with various clinical applications. PATIENTS AND METHODS: Literature review of publications concerning autologous fat grafting. RESULTS: Since its introduction, lipofilling has become increasingly popular; however, its results are variable and unpredictable. Several modifications have been made to the procedures of fat harvesting, processing, and injecting. Surgical excision and low negative-pressure aspiration with large-bore cannulas minimize adipocyte damage during fat harvesting. The "wet" method of fat harvesting involves fluid injection at the donor site and facilitates lipoaspiration while minimizing pain and ecchymosis. For fat processing, centrifugation at a low speed is preferable to high-speed centrifugation, gravity separation or filtration. Fat injection at the recipient site should be performed using small-gauge cannulas in a fanning out pattern over multiple sessions, rather than a single session. Fat grafts exhibit not only dermal filler properties but also regenerative potential owing to the presence of stem cells in fat tissue. Thus, the clinical applications of autologous fat grafting include correction of secondary contour defects after breast reconstruction, release of painful scar contractures, and treatment of burn scars and radiodermatitis. Lipofilling is also used in aesthetic surgery, such as facial and hand rejuvenation, augmentation rhinoplasty, and breast and gluteal augmentation. The complications of lipofilling are minimal and include bruising, swelling, pain, infection, necrosis, and calcification. CONCLUSIONS: Lipofilling is a low-risk procedure that can be used to correct soft-tissue defects in the face, trunk, and extremities, with minimal discomfort for patients.

The biological and clinical basis for the use of adipose-derived stem cells in the field of wound healing.

Worldwide, hard-to-heal lower limb wounds are estimated to affect 1.5-3% of the adult population with a treatment-related annual cost of $10 billion. Thus, chronic skin ulcers of the lower limb are a matter of economic and public concern. Over the years, multiple medical and surgical approaches have been proposed but they are still inadequate, and no effective therapy yet exists. Regenerative medicine and stem cell-based therapies hold great promise for wound healing. Recently, many plastic surgeons have studied the potential clinical application of adipose-derived stem cells (ASCs), which are a readily available adult stem cell population that can undergo multilineage differentiation and secrete growth factors that can enhance wound-healing processes by promoting angiogenesis, and hence increase local blood supply. ASCs have been widely studied in vitro and in vivo in animal models. However, there are few randomized clinical trials on humans, and these are still ongoing or recruiting patients. Moreover, there is no consensus on a common isolation protocol that is clinically feasible and which would ensure reproducible results. The authors aim to provide readers with an overview of the biological properties of ASCs as well as their clinical application, to help better understanding of present and future strategies for the treatment of hard-to-heal wounds by means of stem cell-based therapies.

Autologous fat transplantation for breast reconstruction: A literature review.

INTRODUCTION: The use of autologous fat transplantation to correct volume and contour defects, scars, and asymmetry after breast cancer surgery has increased over the past 20 years. Many developments and refinements in this technique have taken place in recent years, and several studies of the safety of lipofilling in the breast have been published. PRESENTATION OF CASE: We performed a literature review of this technique, highlighting the crucial role of lipofilling in breast cancer reconstruction. DISCUSSION: The efficacy of the fat graft transplantation depends on the experience and the technique used by the surgeon. The ASCs (adipose-derived stem cells) contained in the fat graft has proven to be crucial for breast reconstruction by mean the regeneration of tissue, through the chemotactic, paracrine, and immunomodulatory activities and their in situ differentiation. CONCLUSION: The role of lipofilling for breast reconstruction could be more significant with the application of the findings of experimental research on tissue engineering and ASCs.

Post-bariatric body contouring: oue experience.

Obesity is a growing socio-economic problem especially in the western population. Patients who are undergoing bariatric surgery after a significant weight loss have an altered body profile which may have an important psychological impact. These patients may be candidates for surgical body-lifting. The aim of body-lifting is to obtain a firmer, tighter, rejuvenated appearance for patients who have lax, ptotic tissues. In this paper we describe our experience with two techniques currently practiced by our team, brachioplasty and thigh lift, reporting the indications, the surgical technique and possible complications.

Adipose-derived Stem Cells Added to Platelet-rich Plasma for Chronic Skin Ulcer Therapy.

INTRODUCTION: Adipose-derived stem cells (ASCs) hold great promise for regenerative medicine applications due to their ability to promote the healing process through in situ differentiation and secretion of paracrine factor. The aim of this paper is to present a clinical adjunct for chronic skin wound therapy based on ASCs added to platelet-rich plasma (PRP), to obtain an enhanced PRP (e-PRP). MATERIALS AND METHODS: For 18 months, 24 control-group patients with 31 chronic skin ulcers were treated with standard wound care, while 16 experimental-group patients with 21 chronic skin ulcers were treated with standard wound care and 1 e-PRP injection. The patients were randomly assigned to the control or experimental group. Outpatients had weekly follow-up visits where they were subjected to standard treatment and the wound healing process was assessed. RESULTS: At the end of the study, the control and experimental groups had similar healing rates but wound closure rates were significantly different (P = 0.0257): 0.0890 cm(2) x day and 0.2287 cm(2) x day respectively, resulting in a faster recovery for the group treated with e-PRP. No side effects were reported. CONCLUSION: In the authors' experience, e-PRP significantly enhanced wound closure rates when compared to standard wound care, without causing any serious complications. This finding highlights e-PRP as a valuable resource for chronic wound treatment.

Post-bariatric abdominoplasty: our experience.

The fast increase in obesity has been followed by the growth in the demand for plastic surgery in formerly obese patients. The weight loss is accompanied by new dysfunctions and disorders of the outline of the body that affects the quality of life of the patient. Abdominoplasty is a cosmetic surgery procedure that aims to remove the excess of skin and the redundant fat. The aim of this paper was to analyze our experience in this field and to test how functional abdominoplasty improved quality of life in the operated patients. In our Unit from January 2012 to December 2014, 25 patients (18 women and 7 men, age: 24 - 79 years, mean: 51 years) underwent abdominoplastic surgery. Only at least six months after bariatric surgery the patients were eligible for functional abdominoplasty. Average weight of the patients before surgery was 83.5 kg (range 58 - 163 Kg); averege BMI was 31 (range 24.77 - 57). The average quantity of tissue removed was 1.765 Kg (range 250 g - 11,5 Kg). Minor complications rate was in agreement with the percentages reported in literature. No mortality and major complications have occurred in our series. The majority of patients undergoing post-bariatric abdominoplasty reported an improvement in the quality of life and psychological well-being. In our opinion, however, only a multidisciplinary (surgical, psychological, dietological) approach of the post-bariatric patient allows to maintain long-term aesthetic and functional results.

Analysis of Complications in Postbariatric Abdominoplasty: Our Experience.

Abdominoplasty is one of the most popular body-contouring procedures. It is associated with a significant number of complications: the most common ones are seroma, hematoma, infection, wound-healing problems, and skin flap necrosis. From January 2012 to December 2014, 25 patients (18 women and 7 men) (mean age: 51 years) underwent abdominoplastic surgery at the Plastic Surgery Section, Department of Surgical Sciences, University of Parma, Italy. All patients reported a weight loss between 15 kg and 47 kg. All of the of 25 patients were included in the study; minor and major complications were seen in 17 (68%) and 8 (32%) patients, respectively. The percentage of complications in our patients was as follows: 9 patients with seroma (36%); 4 patients with wound dehiscence with delayed wound healing (16%); 3 cases with hematoma (12%); 2 patients with postoperative bleeding (8%); 1 patient (4%) with an umbilical necrosis; 1 patient (4%) with a deep vein thrombosis; 3 patients with infected seroma (12%); and 2 patients with wound infection (8%). There were no cases of postoperative mortality. The aim of this study is to analyze our complications in postbariatric abdominoplasty.

Role of adipose-derived stem cells in chronic cutaneous wound healing.

AIM: Adipose tissue represent an alternative source of multipotent stem cells with characteristics similar to bone marrowderived mesenchymal stem cells (BMSCs), easier to isolate and effective in wound healing enhancement. MATERIAL OF STUDY: Each patient being considered for stem cells graft was subjected to a conventional liposuction procedure (local anaesthesia, aspirated volume about 80cc), in order to isolate a pellet of adipose-derived stem cells (ASCs), which was then mixed with the platelet-rich plasma (PRP) previously collected, in order to obtain an enhanced-ASCs- PRP (e-PRP), now ready for grafting in the context of skin edges as well as at the bottom of the lesion itself. RESULTS: Flow cytometric analysis performed on the pellet obtained with our isolation process, showed that a mean of 5 x 105 ASCs (range: 4,0-6,0 x 105, SD: ± 1 x 105) were collected from 80 ml of adipose tissue, harvested with standard wet liposuction procedure. It represented the 5% of all sample cells (1 x 107), while the others 95% were mostly being blood-derived and endothelial cells. DISCUSSION: By now, the most used isolation protocols take about two hours due to the complex isolation procedure, requiring both animal-derived reagents and collagenase. The amount of ASCs obtained with our isolation process is sufficient to be directly engrafted in the wound without the need of in vitro expansion but, neither serum nor animalderived reagents are used, and it takes only 15' minutes. CONCLUSION: ASCs application is an innovative, effective approach in the treatment of chronic wounds.

Effects of Topic Simvastatin for the Treatment of Chronic Vascular Cutaneous Ulcers: A Pilot Study.

Recent research suggests that statins might be useful in the process of wound healing, playing a positive immune-modulatory role, improving microvascular function and reducing oxidative stress. The aim of this pilot study was to evaluate the efficacy of topic application of Simvastatin-based cream in the treatment of chronic vascular cutaneous ulcers, comparing this type of treatment to a collagen-based dressing, proven to be effective for ulcer treatment. A total of 20 ulcers were studied in 2 Groups of randomly-chosen patients for a period of one month. In the first Group a 0.5% Simvastatin-based cream was topically administered, while the second Group (control) was treated with an absorbable type I bovine collagen-based medication. Each week, wound healing progress was observed in both Groups, and the ulcers photographed. Wound healing rate was calculated by considering the absolute change in area and by the formula "healing ratio (%) = [(Area0 - Areat4)/Area0] × 100," both sets of data being related to the days comprised in the study in order to calculate healing rate per day. Statistical analysis was performed by Student t test. Study endpoint equaling the time-course changes of ulcer areas. At the end of the study, when considering absolute change in area, the experimental Group appeared to heal better and faster than the control Group although differences between the Groups were not statistically significant. Conversely, rates of wound healing in the experimental and control Groups were 46.88% and 64% respectively, revealing statistically significant differences. (P < 0.05). In conclusion, topic application of a simvastatin-based cream proved to be well- tolerated but not effective in the management of vascular leg ulcers in a 4 week-period.

Endoscopic forehead surgery for migraine therapy Personal technique.

AIM: The aim of this study is to prove the therapeutic effectiveness of nerve decompression, performed endoscopically for frontal migraine and by open surgery for occipital migraine. MATERIALS AND METHODS: Twenty patients were enrolled and underwent surgery for endoscopic resection of the glabellar muscle group, including the corrugator supercilii, depressor supercilii, and procerus muscles, while the occipital decompression was performed in open surgery through decompression of occipital nerves from occipital, semispinalis capitis, trapezius and sternocleidomastoid muscles. Every patient was diagnosed with: migraine without aura, chronic tensiontype headache and new daily persistent headache, refractory to medical management. RESULTS: Analyzing the answers given by the patients to validated questionnaires, 9 referred alleviation of migraine symptoms (45%), 8 described elimination of their migraine headaches (40%) while 3 didn't report any improvement. DISCUSSION: Our data confirmed the results of previous studies, pointing out the effectiveness of trigeminal branches and occipital nerves (trigger points) decompression from the surrounding muscles. Moreover, our technique has the same results but it's less invasive and has less collateral effects. CONCLUSIONS: Our results highlight migraine surgery as an effective treatment for patients with migraine headaches who do not tolerate or do not wish to continue medical interventions. KEY WORDS: Endoscopic surgery, Headache migraine.
