RESUMEN

Background: Male breast cancer (BC) is rare, managed by extrapolation from female BC. The International Male BC Program aims to better characterize and manage this disease. We report the results of part I, a retrospective joint analysis of cases diagnosed during a 20-year period. Methods: Patients with follow-up and tumor samples, treated between 1990 and 2010, in 93 centers/9 countries. Samples were centrally analyzed in three laboratories (the United Kingdom, the Netherlands and the United States). Results: Of 1822 patients enrolled, 1483 were analyzed; 63.5% were diagnosed between 2001 and 2010, 57 (5.1%) had metastatic disease (M1). Median age at diagnosis: 68.4 years. Of 1054 M0 cases, 56.2% were node-negative (N0) and 48.5% had T1 tumors; 4% had breast conserving surgery (BCS), 18% sentinel lymph-node biopsy; half received adjuvant radiotherapy; 29.8% (neo)adjuvant chemotherapy and 76.8% adjuvant endocrine therapy (ET), mostly tamoxifen (88.4%). Per central pathology, for M0 tumors: 84.8% ductal invasive carcinomas, 51.5% grade 2; 99.3% estrogen receptor (ER)-positive; 81.9% progesterone receptor (PR)-positive; 96.9% androgen receptor (AR)-positive [ER, PR or AR Allred score ≥3]; 61.1% Ki67 expression low (<14% positive cells); using immunohistochemistry (IHC) surrogates, 41.9% were Luminal-A-like, 48.6% Luminal-B-like/HER-2-negative, 8.7% HER-2-positive, 0.3% triple negative. Median follow-up: 8.2 years (0.0-23.8) for all, 7.2 years (0.0-23.2), for M0, 2.6 years (0.0-12.7) for M1 patients. A significant improvement over time was observed in age-corrected BC mortality. BC-specific-mortality was higher for men younger than 50 years. Better overall (OS) and recurrence-free survival (RFS) were observed for highly ER+ (P = 0.001), highly PR+ (P = 0.002), highly AR+ disease (P = 0.019). There was no association between OS/RFS and HER-2 status, Ki67, IHC subtypes nor grade. Conclusions: Male BC is usually ER, PR and AR-positive, Luminal B-like/HER2-negative. Of note, 56% patients had T1 tumors but only 4% had BCS. ER was highly positive in >90% of cases but only 77% received adjuvant ET. ER, PR and AR were associated with OS and RFS, whereas grade, Ki67 and IHC surrogates were not. Significant improvement in survival over time was observed.

RESUMEN

This study analyses the difference in 25OH-vitamin D values between two groups of patients both affected by severe osteoporosis with fragility fractures, but one group has vertebral fractures and the other one has hip fractures. Patients with hip fractures have vitamin D values lower than patients with vertebral fractures. INTRODUCTION: The purpose of this study was to evaluate 25OHD levels in patients with fragility vertebral fractures (VF) and hip fractures (HF) and make a comparison between the groups. METHODS: In the first group were enrolled ambulatory patients with 3 or more moderate to severe VF; in the second group were enrolled patients hospitalized in the Department of Orthogeriatrics undergoing surgery for HF. For all patients, we collected values of 25OHD and PTH. The group of patients with VF was further subdivided into pre-existing VF or recent VF treated within 30 days with vertebroplasty. RESULTS: The sample consists of 180 subjects divided into two groups: 90 with VF and 90 with HF. The average value of 25OHD in the total sample was 13.2 ± 9.6 ng/ml, Vitamin D was significantly lower in the HF group than the VF group (p < 0.001)(VF 18.6 ± 9.7 ng/ml, HF 7.9 ± 5.7 ng/ml). The mean PTH value in the total sample was 67.5 ± 54.9 pg/ml and PTH was significantly higher in the HF group compared to the group with VF (p < 0.001) (VF 55.6 ± 27.2 pg/ml, HF 78.7 ± 70.2 pg/ml). The mean 25OHD value in the recent VF group is 16.0 ± 6.6 ng/ml while in the pre-existing VF group is 19.5 ± 10.4 ng/ml with a statistically significant difference (p < 0.001). CONCLUSIONS: Patients of the same age with severe osteoporosis have a lower 25OHD value when the fracture occur at the hip and is recent, probably this is due to the inflammation caused by fracture and/or surgical intervention.

RESUMEN

The effects of cadmium and lead were investigated in Cynara cardunculus L. Plant uptake by root and shoot, changes in cell ultrastructure and photosynthetic efficiency, photosynthetic key protein levels, as well as regulation of stress-induced Hsp70 were examined. Cynara cardunculus accumulated Cd and Pb in their tissue, with a different trend for the two metals. The prompt translocation of Cd to the shoot may justify the ultrastructural injuries, especially observed in chloroplasts. However, Cd- treated plants did not show any decline in photochemistry; it is likely that Cd in shoot tissue triggers defense mechanisms, increasing the level of proteins involved in photosynthesis (i.e., Rubisco and D1 increased 7 and 4.5 fold respectively) as a compensatory response to neutralize chloroplast damage. The accumulation of Pb mainly in root, can explain the increase in Hsp70 level (23 folds) in this tissue. Pb reached the shoots, even at low amounts, causing an overall significant change in some photochemical parameters (QY and NPQ decreases and increases of 25%, respectively). The results suggest a higher sensitivity of C. cardunculus to Pb than Cd, although maximal photochemical efficiency suggests that this species seems to tolerate Pb and Cd and hence, it is a suitable candidate for phytoremediation.

RESUMEN

BACKGROUND: Whole body positron emission tomography (PET)/computed tomography (CT) is a sensitive imaging technique in patients with metastatic melanoma, but its role in the follow-up of asymptomatic high-risk patients is unclear. The aim was to study the role of PET/CT as a routine surveillance imaging tool in asymptomatic high-risk patients at the early stage of follow-up combined with a sufficient follow-up over several years. MATERIAL AND METHODS: A total of 110 asymptomatic patients with clinically local American Joint Committee on Cancer (AJCC) stage IIB-IIIB melanoma underwent routine whole body PET/CT scanning after a mean interval of seven months after initial surgery. Clinical data were retrospectively analyzed after a median follow-up time of 4.6 years. RESULTS: Recurrent melanoma was detected in 45 patients (41%) and 36 (33%) died of melanoma. In 11 asymptomatic patients (10%) occult disease was detected with a single PET/CT. In seven of these patients (64%), positive PET/CT finding had major influence in treatment decisions. Four patients underwent surgical metastasectomy and two of them remained disease-free. In 34 patients (31%) PET/CT revealed no disease, but recurrence was detected at a median time of 19 months after negative PET/CT scan. In 50 patients (45%) PET/CT finding was true negative. In 15 patients (14%) scan was false positive leading to additional management or repetitive imagings. CONCLUSION: A single PET/CT could detect 24% of all recurrences in asymptomatic melanoma patients at the early stage of follow-up, but an earlier detection of occult metastases did not improve survival.

RESUMEN

BACKGROUND: Research on temporal mortality trends for stage IV breast cancer is limited, especially among older patients by race. We evaluated factors associated with overall, breast cancer-specific and other-cause mortalities using contemporary population data. PATIENTS AND METHODS: Using the Surveillance, Epidemiology, and End Results-Medicare linked data, we identified older women (≥ 66 years) with stage IV breast cancer diagnosed in 2002-2009. Overall mortality was estimated by the Kaplan-Meier method, compared by log-rank tests, and modeled by Cox models. Competing risk analysis was used to evaluate breast cancer-specific and other-cause mortalities. RESULTS: The median overall survival time for non-Hispanic blacks improved from 8.6 months in 2002-2003 to 9.9 months in 2007-2009, whereas that for non-Hispanic whites improved from 12.1 to 14.8 months. In the multivariate model, the risk of breast cancer-specific death for patients diagnosed in 2007-2009 was significantly lower (P = 0.02), whereas the risk of other-cause mortality changed little (P = 0.88) compared with those risks for patients diagnosed in 2002-2003. Non-Hispanic blacks had the higher risk of both mortality types compared with non-Hispanic whites; a diagnosis time-race interaction term was not statistically significant for either cause of death. CONCLUSION: Breast cancer-specific mortality among older women modestly improved from 2002 to 2009 across all races, but not other-cause mortality. Racial disparity in mortality persisted, but did not widen in this period. Efforts should be devoted to improving other-cause mortality for all women, with special attention toward decreasing breast cancer mortality for non-Hispanic black women.

RESUMEN

BACKGROUND: Everolimus synergistically enhances taxane-induced cytotoxicity in breast cancer cells in vitro and in vivo in addition to demonstrating a direct antiproliferative activity. We aim to determine pharmacodynamics changes and response of adding everolimus to standard neoadjuvant chemotherapy in triple-negative breast cancer (TNBC). PATIENTS AND METHODS: Phase II study in patients with primary TNBC randomized to T-FEC (paclitaxel 80 mg/m(2) i.v. weekly for 12 weeks, followed by 5-fluorouracil 500 mg/m(2), epirubicin 100 mg/m(2), and cyclophosphamide 500 mg/m(2) every 3 weeks for four cycles) versus TR-FEC (paclitaxel 80 mg/m(2) i.v. and everolimus 30 mg PO weekly for 12 weeks, followed by FEC). Tumor samples were collected to assess molecular changes in the PI3K/AKT/mTOR pathway, at baseline, 48 h, 12 weeks, and at surgery by reverse phase protein arrays (RPPA). Clinical end points included 12-week clinical response rate (12-week RR), pathological complete response (pCR), and toxicity. RESULTS: Sixty-two patients were registered, and 50 were randomized, 27 received T-FEC, and 23 received TR-FEC. Median age was 48 (range 31-75). There was downregulation of the mTOR pathway at 48 h in the TR-FEC arm. Twelve-week RR by ultrasound were 29.6% versus 47.8%, (P = 0.075), and pCR were 25.9% versus 30.4% (P = 0.76) for T-FEC and TR-FEC, respectively. mTOR downregulation at 48 h did not correlate with 12-week RR in the TR-FEC group (P = 0.58). Main NCI grade 3/4 toxicities included anemia, neutropenia, rash/desquamation, and vomiting in both arms. There was one case of grade 3 pneumonitis in the TR-FEC arm. No grade 3/4 stomatitis occurred. CONCLUSION: The addition of everolimus to paclitaxel was well tolerated. Everolimus downregulated mTOR signaling but downregulation of mTOR at 48 h did not correlate with 12-week RR in the TR-FEC group. CLINICAL TRIAL NUMBER: NCT00499603.

RESUMEN

PURPOSE: Despite international guidelines being available, not all gender clinics are able to face gender dysphoric (GD) youth population needs specifically. This is particularly true in Italy. Centers offering specialized support are relatively few and a commonly accepted Italian approach to GD youth has still not been defined. The aim of the present Position Statement is to develop and adhere to Italian guidelines for treatment of GD adolescents, in line with the "Dutch Approach", the Endocrine Society (ES), and the World Professional Association for Transgender Health (WPATH) guidelines. METHODS: An in-depth brainstorming on the application of International guidelines in the Italian context was performed by several dedicated professionals. RESULTS: A staged approach, combining psychological support as well as medical intervention is suggested. In the first phase, individuals requesting medical help will undergo a psycho-diagnostic procedure to assess GD; for eligible adolescents, pubertal suppression should be made available (extended diagnostic phase). Finally, from the age of 16 years, cross-sex hormonal therapy can be added, and from the age of 18 years, surgical sex reassignment can eventually be performed. CONCLUSIONS: The current inadequacy of Italian services offering specialized support for GD youth may lead to negative consequences. Omitting or delaying treatment is not a neutral option. In fact, some GD adolescents may develop psychiatric problems, suicidality, and social marginalization. With access to specialized GD services, emotional problems, as well as self-harming behavior, may decrease and general functioning may significantly improve. In particular, puberty suppression seems to be beneficial for GD adolescents by relieving their acute suffering and distress and thus improving their quality of life.

RESUMEN

BACKGROUND: To determine the relationship between obesity, diabetes, and survival in a large cohort of breast cancer patients receiving modern chemotherapy and endocrine therapy. PATIENTS AND METHODS: We identified 6342 patients with stage I-III breast cancer treated between 1996 and 2005. Patients were evaluated according to body mass index (BMI) category and diabetes status. RESULTS: In a multivariate model adjusted for body mass index, diabetes, medical comorbidities, patient- and tumor-related variables, and adjuvant therapies, relative to the normal weight, hazard ratios (HRs) for recurrence-free survival (RFS), overall survival (OS), and breast cancer-specific survival (BCSS) for the overweight were 1.18 [95% confidence interval (CI) 1.02-1.36], 1.20 (95% CI 1.00-1.42), and 1.21 (95% CI 0.98-1.48), respectively. HRs for RFS, OS, and BCSS for the obese were 1.13 (95% CI 0.98-1.31), 1.24 (95% CI 1.04-1.48), and 1.23 (95% CI 1.00-1.52), respectively. Subset analyses showed these differences were significant for the ER-positive, but not ER-negative or HER2-positive, groups. Relative to nondiabetics, HRs for diabetics for RFS, OS, and BCSS were 1.21 (95% CI 0.98-1.49), 1.39 (95% CI 1.10-1.77), and 1.04 (95% CI 0.75-1.45), respectively. CONCLUSIONS: In patients receiving modern adjuvant therapies, obesity has a negative impact on RFS, OS, and BCSS; and diabetes has a negative impact on RFS and OS. Control of both may be important to improving survival in obese and diabetic breast cancer patients.

RESUMEN

BACKGROUND: Approximately 2000 American men are diagnosed with breast cancer every year. Limited data are available evaluating toxicity of antihormonal treatments in male breast cancer patients. PATIENTS AND METHODS: We reviewed male breast cancer patients evaluated at our institution (1999-2009). Of 126 patients, 64 met the following inclusion criteria: stage I-III, treated with tamoxifen, at least one follow-up visit after starting tamoxifen. A descriptive analysis of toxic effects was carried out on these 64 patients. RESULTS: Median follow-up from start of tamoxifen therapy was 3.9 years (range 0.3-19.4 years). Median age at diagnosis was 61 years (range 30-79 years). Breakdown by stage: 29.7% (n = 19) stage I, 54.7% (n = 35) stage II, and 15.6% (n = 10) stage III. Thirty-four (53%) patients experienced one or more toxicity while taking tamoxifen. Most common toxic effects are weight gain (14 patients, 22%) and sexual dysfunction (14 patients, 22%). Thirteen (20.3%) patients discontinued tamoxifen due to toxicity: one ocular, one leg cramps, two neurocognitive deficits, two bone pain, three sexual dysfunction, and four thromboembolic events. CONCLUSIONS: To our knowledge, this is the largest study examining tamoxifen-related toxic effects among male breast cancer patients. Among male patients, there is a high rate of discontinuation of tamoxifen. Prospective studies of antihormonal agents in male breast cancer are warranted.

RESUMEN

BACKGROUND: The purpose of this study is to evaluate the risk factors and the prevalence of thromboembolic events (TEEs) in breast cancer patients. PATIENTS AND METHODS: This is a retrospective cohort study using the Surveillance, Epidemiology, and End Results-Medicare database. Breast cancer patients diagnosed from 1992 to 2005 ≥66 years old were identified. International Classification of Diseases, Ninth Revision, and Healthcare Common Procedure Coding System codes were used to identify TEEs within 1 year of the breast cancer diagnosis. Analyses were conducted using descriptive statistics and logistic regression. RESULTS: A total of 89 841 patients were included, of them 2658 (2.96%) developed a TEE. In the multivariable analysis, males had higher risk of a TEE than women [odd ratio (OR) = 1.57; confidence interval (CI) 1.10-2.25] and blacks had higher risk than whites (OR = 1.20; CI 1.04-1.40). Compared with stage I patients, patients with stage II, III and IV had 22%, 39% and 98% increase, respectively, in risk. Placement of central catheters (OR = 2.71; CI 2.43-3.02), chemotherapy treatment (OR = 1.66; CI 1.48-1.86) or treatment with erythropoiesis-stimulating agents (ESAs) (OR = 1.33; CI 1.33-1.52) increase the risk. Other significant predictors included comorbidities, age, receptor status, marital status and year of diagnosis. Similar estimates were seen for pulmonary embolism, deep vein thromboembolism and other TEEs. CONCLUSIONS: In total, 2.96% of patients in this cohort developed a TEE within 1 year from breast cancer diagnosis. Stage, gender, race, use of chemotherapy and ESAs, comorbidities, receptor status and catheter placement were associated with the development of TEEs.

RESUMEN

In this study cytological ultrastructure, total content of C, N and S, and cellular location of major and trace elements (K, Ca, Mg, Cu, Pb and Zn) were investigated in the moss Hypnum cupressiforme and in the lichen Pseudevernia furfuracea exposed in bags for a spring-summer 12-weeks period in the urban area of Naples city. In the moss, severe ultrastructural damages, such as membrane interruptions and dehydration, developed after exposure supporting the occurrence of a dead biomonitor. In the lichen, the post-exposure stress marks, such as the development of lysosome-like vesicles and concentric bodies, or the production of melanin, were overall compatible with life. With exposure, N, S, major and trace element contents all increased in both biomonitors, while C remained substantially unchanged. Copper and Pb were mainly retained in extracellular and particulate forms. Intracellular concentration of Zn consistently increased in both biomonitors, irrespective of their vitality. In transplants, cellular location of elements can better reflect the form in which they occur in the environment.

RESUMEN

OBJECTIVES: To describe clinical characteristics, laboratory tests, radiological data and outcome of pediatric cases with SARS-CoV-2 infection complicated by neurological involvement. STUDY DESIGN: A computerized search was conducted using PubMed. An article was considered eligible if it reported data on pediatric patient(s) with neurological involvement related to SARS-CoV-2 infection. We also described a case of an acute disseminated encephalomyelitis (ADEM) in a 5-year-old girl with SARS-CoV-2 infection: this case was also included in the systematic review. RESULTS: Forty-four articles reporting 59 cases of neurological manifestations in pediatric patients were included in our review. Most (32/59) cases occurred in the course of a multisystem inflammatory syndrome in children (MIS-C). Neurological disorders secondary to cerebrovascular involvement were reported in 10 cases: 4 children with an ischemic stroke, 3 with intracerebral hemorrhage, 1 with a cerebral sinus venous thrombosis, 1 with a subarachnoid hemorrhage, 1 with multiple diffuse microhemorrhages. Reversible splenial lesions were recognized in 9 cases, benign intracranial hypertension in 4 patients, meningoencephalitis in 4 cases, autoimmune encephalitis in 1 girl, cranial nerves impairment in 2 patients and transverse myelitis in 1 case. Five cases had Guillain-Barré syndrome (GBS) and two, including ours, had ADEM. Radiological investigations were performed in almost all cases (45/60): the most recurrent radiological finding was a signal change in the splenium of the corpus callosum. The presence of SARS-CoV-2 viral nucleic acid in the cerebrospinal fluid was proved only in 2 cases. The outcome was favorable in almost all, except in 5 cases. CONCLUSIONS: Our research highlights the large range of neurological manifestations and their presumed pathogenic pathways associated with SARS-CoV-2 infection in children. Nervous system involvement could be isolated, developing during COVID-19 or after its recovery, or arise in the context of a MIS-C. The most reported neurological manifestations are cerebrovascular accidents, reversible splenial lesions, GBS, benign intracranial hypertension, meningoencephalitis; ADEM is also a possible complication, as we observed in our patient. Further studies are required to investigate all the neurological complications of SARS-CoV-2 infection and their underlying pathogenic mechanism.

RESUMEN

BACKGROUND: The objective of this retrospective study was to determine whether differences in survival exist between women with de novo stage IV and relapsed breast cancer. PATIENTS AND METHODS: Three thousand five hundred and twenty-four women with de novo stage IV or relapsed breast cancer diagnosed from 1992 to 2007 were identified. Disease-free interval (DFI) was defined as the time from the diagnosis of primary nonmetastatic breast cancer to the date of the first distant metastases. Kaplan-Meier product limit method was used to estimate overall survival (OS). Cox proportional hazards model was fitted to determine the association between metastatic disease (relapsed versus de novo) and OS after controlling for other patient/tumor characteristics. RESULTS: Six hundred and forty-three (18.2%) women had de novo stage IV disease and 2881 (81.8%) had relapsed disease. Median follow-up was 19 months. Median OS among patients with de novo stage IV and relapsed disease was 39.2 and 27.2 months, respectively (P < 0.0001). In the multivariable model, women with relapsed disease had an increased risk of death compared with patients with de novo disease (HR = 1.75, 95% confidence interval 1.47-2.08, P < 0.0001). When the multivariable model was stratified by DFI, women with relapsed disease with DFI <6 months, ≥6 months to <2 years, or ≥2 to <5 years each had a significantly higher risk of death compared with women with de novo stage IV disease. The risk of death was not statistically different among patients with relapsed disease with DFI >5 years compared with those with de novo disease. CONCLUSIONS: This large cohort study provides further insight into the natural history of relapsed and de novo stage IV breast cancer. DFI plays an important role in the prognosis for patients with relapsed breast cancer.

RESUMEN

BACKGROUND AND PURPOSE: Pregabalin has demonstrated efficacy in controlled trials as adjunctive treatment in patients with refractory seizures. METHODS: This open-label, 21-week study in adults with at least two partial seizures in the last 2 months, who were inadequately controlled with one to three antiepileptic drugs, evaluated pregabalin 150-600 mg/day (dosed twice daily). The study comprised a prospective or retrospective 8-week baseline phase, and 9-week dose optimization and 12-week maintenance periods. The primary assessment was the mean percentage change in 28-day seizure frequency between baseline and end-point (last 12 weeks of treatment, last observation carried forward, modified intention-to-treat population). RESULTS: Four hundred and seventy-six patients from Europe were included in this study (51% men; mean age/epilepsy duration 40.1/24.1 years). The median baseline seizure frequency was 5.5/28 days. Amongst the patient population, 78% completed the 21-week treatment period; 7% discontinued for lack of efficacy and 12% because of adverse events (AEs). The mean last pregabalin dose was 359 mg/day. The mean (95% CI) reduction in seizure frequency was 36% (31%; 41%). The median reduction was 33%, and 39% of patients had a >or=50% reduction in seizure frequency. There were 19% and 8% of patients free of seizures during their last 4 and 12 weeks of treatment, respectively. The three most common AEs were dizziness (17%), somnolence (13%) and weight increase (13%). CONCLUSIONS: This open-label study of pregabalin demonstrated efficacy that was consistent with that observed in previous controlled epilepsy trials. Pregabalin was well tolerated. The AE profile was also consistent with that reported in previous trials.

RESUMEN

BACKGROUND: there is major variability in how the gastrojejunostomy (GJ) is created when laparoscopic gastric bypass (LRYGB) is performed. This is a prospective, non-randomised pilot comparison of two different techniques during our learning curve period performed by two different surgeons with similar surgical experience. METHODS: from March 2006 until May 2008, 71 consecutive patients, 28 men and 43 woman, mean age 44 (range 24 to 62 years) who were operated for morbid obesity by laparoscopic by-pass surgery have been included. Mean preoperative Body Mass Index (BMI) (range) was 47 (34-63). The patients were divided into two groups on the basis of the stapler used. Group 1 comprised 30 patients who underwent surgery using a 25 mm circular stapler to create the GJ. Group 2 comprised 41 patients who underwent surgery using a 45 mm, blue cartridge linear stapler. Operative time, intra-operative complications, hospital stay, major and minor complications were detected. RESULTS: intra-operative complications occurred in 4 patients (13.3%) in Group 1, in 5 patients (12.2%) in Group 2. Re-operations occurred 3 times (10.0%) in Group 1, and 4 times (9.8%) in Group 2 due to anastomotic complications, bleeding and/or bowel obstruction. Major complications occurred in four patients in Group 1 (13.3%) and in seven patients in Group 2 (17.1%). There was a significant difference in the overall morbidity rate (major and minor complications), which was 56.7% in Group 1 and 34.1% in Group 2 (p = 0.05). Mean operative time in Group 1 was 135 minutes, and in Group 2 122 minutes. Mean hospital stay was significantly shorter in Group 2 (3.9 days) than in Group 1 (5.7 days, p = 0.04). CONCLUSIONS: learning to handle the technique when performing the gastrojejunostomy during laparoscopic gastric bypass surgery may be faster and easier by using the linear stapler. This may be important knowledge for centres considering starting LRYGB practice, although the surgeon factor needs to be taken in account. The results should be interpreted with caution because the confounding effect of one surge-on performing one type of operation while the other surgeon (is performing) the second type of operation could not be taken into account in this prospective non-randomized analysis.

RESUMEN

BACKGROUND AND AIMS: The most effective dissection technique for raising the flap in abdominoplasty is still controversial, particularly in high-risk massive-weight-loss patients. LigaSure Impact™ vessel-sealing system (Medtronic, Dublin, Ireland) is an energy device commonly used among different surgical specialties to reduce morbidity and implement outcomes. The aim of this study was to investigate the effectiveness of LigaSure Impact in abdominoplasty compared with the conventional techniques, diathermia. MATERIAL AND METHODS: Patients underwent primary abdominoplasty after massive weight loss at a single center from 1 January 2008 to 31 May 2015 and were retrospectively reviewed. A total of 94 patients eligible for the study were divided into two groups on basis of the dissection technique: LigaSure Impact group (29 patients) and the conventional technique group (65 patients). Total intraoperative blood loss was the primary endpoint. Duration of the operation, perioperative complications and re-operation were recorded as secondary endpoints. RESULTS: Baseline characteristics were well balanced between the groups. Significant differences were found in intraoperative blood loss favoring LigaSure Impact group (259.6 ± 198.8 mL vs 377.9 ± 190.0 mL, p = 0.004) and blood transfusion rates (13.8% vs 35.4%, p = 0.047). In contrast, operative time was significantly longer in LigaSure Impact group (168.6 ± 121.2 vs 179.7 ± 57.6 min, p = 0.005), while a tendency to shorter hospital stay was found in LigaSure Impact group (3.6 ± 1.1 days vs 4.6 ± 3.2 days, p = 0.081). Overall complications occurrence, Clavien-Dindo grade II (24.1% vs 55.4%) and grade III (13.8% vs 30.8%) complications were significantly lower in LigaSure Impact group (respectively, p = 0.005, p = 0.007, p = 0.016). Late (>30 days) re-operation rate was significantly lower in the LigaSure Impact group (6.9% vs 27.70%, p = 0.0028). Specific wound complications showed no significant difference. CONCLUSION: LigaSure Impact vessel-sealing system may be beneficial in improving abdominoplasty outcomes in massive-weight-loss patients because it might reduce blood loss, need for transfusions, complications, and re-operations.

RESUMEN

INTRODUCTION: The medial plantar artery (MPA) flap in its anterograde form is considered the gold standard for heel reconstruction. This flap can be also raised distally for the reconstruction of the weight-bearing forefoot. However, terminal branches of the MPA, together with their connection with distal and dorsal systems, can be variable. Our objective was to provide a comprehensive anatomic description that could match all technical possibilities in raising the distally based MPA flap. A systematic review of indication outcomes and complications of the distally based MPA flap is provided. METHODS: According to PRISMA criteria, we systematically reviewed previous literature using the MEDLINE database concerning the MPA flap from 1977 to November 2018 using the keywords « Medial plantar flap ¼ OR « Medial Plantar Artery ¼. Anatomic variations, techniques, indications, outcomes, and complications were analyzed. RESULTS: All different vascular pedicles that may be used for the vascularization of the MPA flap were classified. Apart from the flap with a proximal flow, there may be five anastomotic connections from the superficial MPA to the plantar arterial network. Four dorso-plantar links supply the plantar network thanks to dorsal vascularization. Literature analysis of outcomes showed how the retrograde MPA flap may be unreliable with 14% of venous congestion rate and 9.3% of average flap loss, for a total average flap complication of 18.6%. CONCLUSION: This review provides the ultimate, clear picture of the complex anastomosis of the forefoot, with direct referral to surgical flap raising techniques, guiding surgeons during challenging reconstructions.
