RESUMO

BACKGROUND: While the effects of androgens on muscle are well described in hypogonadal men, literature is still scarce on muscular strength or size variations in transmen; in this population there are no data regarding the relative effect of testosterone (T) and its metabolite dihydrotestosterone on muscle. AIM: Our primary objective was to compare the effects on muscle strength of 54-week administration of testosterone undecanoate (TU) combined with the 5α-reductase inhibitor dutasteride (DT) or placebo (PL). Secondary outcomes included evaluation of body composition, bone, cutaneous androgenic effects, and metabolic variations. METHODS: In this randomized, double-blind PL-controlled pilot trial, 16 ovariectomized transmen were randomized to receive TU 1,000 mg IM at week 0, 6, 18, 30, 42 plus a PL pill orally daily (TU + PL, n = 7) or plus DT 5 mg/d (TU + DT, n = 7). OUTCOMES: At week 0 and 54 the following parameters were evaluated: isokinetic knee extension and flexion peak torque and handgrip strength, body composition, and bone mineral density, biochemical, hematological, and hormonal parameters. RESULTS: Handgrip and lower limb strength increased significantly in both groups with no differences between the 2 groups. Fat mass decreased and lean mass increased significantly similarly in both groups. Metabolic parameters remained stable in the 2 groups except for high-density lipoprotein cholesterol that was reduced in both groups. Hepatic and renal function remained normal in both groups and no major adverse effects were registered in either group. CLINICAL IMPLICATIONS: These results may be particularly relevant for transmen experiencing cutaneous androgenic adverse events such as acne and androgenetic alopecia and in light of the development of non-5α-reduced androgens. STRENGTHS & LIMITATIONS: The strength of this study was the randomized, double-blind PL-controlled design, while the small number of subjects was definitely the biggest limitation. CONCLUSION: For the first time we demonstrated that the addition of DT does not impair the anabolic effects of T on muscles in transmen previously exposed to T, supporting the hypothesis that the conversion in dihydrotestosterone is not essential for this role.

RESUMO

Closure of a tracheoesophageal puncture site performed during voice prosthesis implantation may sometimes be required. Besides local techniques, more elaborate procedures, such as closure by means of free microvascular flaps, have been advocated. In this report, we describe a case of local treatment of a hard-to-heal fistula with local application of autologous platelet-rich fibrin matrix in a 77-year-old male patient. At one-week follow-up, the size of the fistula had decreased dramatically but some leakage remained when drinking. After one month, the patient was able to drink and eat normally without any leakage. There was no recurrence of the leakage at two years' follow-up. In summary, local application of platelet-rich fibrin seems to be a simple, safe and effective procedure for tracheoesophageal fistula closure.

RESUMO

BACKGROUND: Nipple areola complex (NAC) sparing mastectomy allows good oncological and aesthetic results. The study compares the results, in terms of self-evaluated satisfaction and symmetry, of direct to implant (DTI) sub-muscular breast reconstruction, with the aid of human acellular dermal matrix (ADM) versus two-stage reconstruction with sub-muscular tissue expander, followed by implant. MATERIALS AND METHODS: This is a retrospective, observational, single-center, non-randomized, case-control study. Inclusion criteria were: unilateral NAC sparing mastectomy at Forlì Hospital between 2014 and 2018; sub-muscular reconstruction; minimum follow-up of 12 months from the reconstructive stage; no history of radiotherapy. Patients were divided into two groups: group A included patients who underwent DTI breast reconstruction with the aid of human ADM; group B were those who underwent a two-stage reconstruction with tissue expander then implant. We collected data on: (1) Self-evaluated satisfaction by Breast Q questionnaire (scores from 0 to 100). (2) Observer-evaluated symmetry. Bi-dimensional photographs were collected and evaluated by 11 breast surgeons blinded to each other, who assigned a score for symmetry (from 0 to 10). (3) Symmetry of anthropometric measures collected by hand and volume estimated by Breast V application. RESULTS: Group A included 28 patients; group included B 26 patients. Breast-Q questionnaires reported the following results: satisfaction with breasts in group A 65 ± 12 versus group B 68 ± 14; satisfaction with outcome in group A 88 ± 16 versus group B 93 ± 11; psychosocial well-being in group A 71 ± 20 versus group B 76 ± 17; sexual well-being in group A 63 ± 26 versus group B 60 ± 13; physical well-being in group A 68 ± 15 versus group B 60 ± 12. The average symmetry breast score assigned to group A was 6.9, versus group B 7.2. Regarding the anthropometric measures in group A, the differences between right and left were major to those in group B. Regarding breast volume, the mean difference between right and left in group A was 31.89 cc ± 24.97, whereas in group B was 25.46 cc ± 23.59. CONCLUSION: Our data show better symmetry and better psychosocial well-being in the two-stage reconstruction, and higher satisfaction with sexual and physical well-being in DTI reconstructions. These aspects should be discussed with the patient while collecting the informed consent. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

RESUMO

BACKGROUND: Craniofacial morphogenesis is the result of an intricate multistep network of tightly controlled spatial and temporal signalling that involves several molecules and transcription factors organized into highly coordinated pathways. Any alteration in even one step of this delicate process can lead to congenital malformations such as cleft palate. One of the first steps in embryonal orofacial development is the migration of cells from the neural crests to the branchial arches. Next, the cells have to proliferate, differentiate, move and connect to each other in order to correctly form the palate. Cell contraction, promoted by the interaction of non-muscle myosin II and actin A, is a crucial step in morphogenesis and is regulated by ROCK1 protein. METHODS: A family-based association study was carried out in order to verify whether or not genetic variants of ROCK1 were associated with non-syndromic cleft palate (nsCP). Two cohorts from Italy and Iran, a total of 189 nsCP cases and their parents were enrolled. RESULTS: The rs35996865-G allele was under-transmitted in cases of nsCP [P = .006, odds ratio (OR) = 0.63 (95% CI 0.45-0.88)]. CONCLUSION: This investigation reveals for the first time data supporting a role for ROCK1 in nsCP aetiology.

RESUMO

BACKGROUND: The goal of microsurgical breast reconstruction is to return to the precancer state, maximizing symmetry with less morbidity. This requires a long learning curve, in particular where modeling is concerned. In this context, reverse engineering technologies found an application, allowing the creation of molds that can be used during the surgery. METHOD: We created 10 molds named DIEP sizers, which help to simplify deep inferior epigastric perforator (DIEP) flap insetting. For this, we designed a virtual model using Geomagic X software to construct the sizers. Our model has a thorax circumference, breast projection, and footprint correspondent to an average of the measurements we collected from 15 patients undergoing such surgery. We made a comparative study between 2 groups each of 24 patients, using as comparison criteria surgical times in patients undergoing breast microsurgical reconstruction with or without DIEP sizers. In both groups, we included immediate and delayed reconstructions as well as monolateral, bilateral and monolateral with contralateral symmetrization. RESULT: In all the cases we performed with DIEP sizers, we achieved an average time saving of 105 minutes in monolateral reconstruction, 80 minutes in monolateral reconstruction with contralateral symmetrization, and 120 minutes in bilateral reconstruction (P < 0.001). No major complications occurred. CONCLUSIONS: We performed 24 breast reconstructions with preformed molds, obtaining a proper "library" with different DIEP sizers that can be used both in preoperative planning and in intraoperative modeling. We recommend the use of a preformed mold in microsurgical breast reconstruction to improve symmetry, to shorten the learning curve and to save time.

RESUMO

BACKGROUND: The ischemic environment of the receiving area compromises the outcome of autologous fat grafts. The aim of this study was to isolate and expand the stromal vascular fraction from patient lipoaspirates and investigate the gain in cell viability exerted by some protective agents against the blockage of mitochondrial respiration. METHODS: The aspirates were (1) washed, using the "Lull pgm system," (2) centrifuged and (3) decanted. The corresponding stromal vascular fractions were isolated, and after cell adherence selection, the stromal/stem cell subpopulations were exposed to Antimycin A for 1 h. Then, the protection induced by cell pretreatment with deferoxamine, diazoxide and IGF-1 was evaluated. RESULTS: The residual cell viability of the "Lull pgm system"-washed samples was greater than that of the centrifuged samples (p < 0.05), and this advantage was maintained during the following 12 days of culture. The administration of 400 µM deferoxamine before Antimycin A treatment increased the number of viable cells from 56.5 to 80.8% (p < 0.05). On the contrary, the pretreatment with 250 µM diazoxide or 0.1 µg/ml IGF-1 did not exert any significant pro-survival action. Echinomycin abolished the positive effect of deferoxamine, suggesting that its protection involved HIF-1α. CONCLUSIONS: Adipose-derived stromal-stem cells survive the inhibition of mitochondrial respiration better if the lipoaspirate is washed using the "Lull pgm system" rather than centrifuged. Moreover, a significant contribution to cell survival can be obtained by preconditioning stromal-stem cells with deferoxamine. In a clinical perspective, this drug could be safely administered before surgery to patients undergoing autologous fat transfer.

RESUMO

Many orthodontists working on patients with cleft lip and palate (CLP) have shown great enthusiasm for presurgical infant orthopedics (PSIO) to improve surgical outcomes with minimal intervention. Even though every clinician aims to use the best treatment modality for their patients, PSIO effects can be confounded by surgical type and timing of the primary repair, as is discussed in many studies. In such cases, one should be cautious when evaluating the particular outcomes for patients with CLP since it is difficult to differentiate the sole effect of an individual surgical or orthodontic intervention. As with any treatment methodology, nasoalveolar molding (NAM) has both benefits and limitations. Commonly cited concerns with NAM, and PSIO in general, include increased cost, increased burden of care, and a negative impact on maxillary growth. However, NAM cannot be deemed as having apparent long-term negative or positive effects on skeletal or soft tissue facial growth, based on previous studies. A review of the literature suggests that NAM does not alter skeletal facial growth when compared with the samples that did not receive PSIO. Nevertheless, the published studies on NAM show evidence of benefits to the patient, caregivers, the surgeon, and society. These benefits include documented reduction in severity of the cleft deformity prior to surgery and as a consequence improved surgical outcomes, reduced burden of care on the care givers, reduction in the need for revision surgery, and consequent reduced overall cost of care to the patient and society.

RESUMO

Esthetic masculinization of the chest wall is one of the first surgical steps in female-to-male transsexual (FTMTS) reassignment.This surgical procedure is not a simple mastectomy: it is required for removal of breast tissue with glandular resection and skin excess revision, to reduce and replace the nipple-areola complex in the right location, minimizing chest wall scars. The creation of an esthetically pleasing male chest allows the patient to live at ease in the male gender role.In this article, we present our series of 68 FTMTSs who underwent bilateral mastectomies for surgical sexual reassignment (a total of 136 mastectomies) according to our algorithm, in the period between January 2010 and December 2017. We selected 4 different operative procedures, classified as subcutaneous ("pull-through" and "concentric circular" techniques) and skin extended ("ultrathin vertical bipedicle" and free nipple graft).We achieved a total complication rate of 6.6%, less than that reported in the literature; additional procedures for esthetic improvements were performed in 14.7% of cases. The mean patient satisfaction was approximately 4.57% of a maximal value of 5 (excellent).To help surgeons in choosing the most appropriate FTMTS surgical technique and to reduce unfavorable results, we propose the use of our treatment algorithm in preoperative evaluation of the chest wall according to the breast volume, degree of glandular ptosis, and skin elasticity.

RESUMO

OBJECTIVE: Orofacial development is a complex process subjected to failure impairing. Indeed, the cleft of the lip and/or of the palate is among the most frequent inborn malformations. The JARID2 gene has been suggested to be involved in non-syndromic cleft lip with or without cleft palate (nsCL/P) etiology. JARID2 interacts with the polycomb repressive complex 2 (PRC2) in regulating the expression patterns of developmental genes by modifying the chromatin state. MATERIALS AND METHODS: Genes coding for the PRC2 components, as well as other genes active in cell differentiation and embryonic development, were selected for a family-based association study to verify their involvement in nsCL/P. A total of 632 families from Italy and Asia participated to the study. RESULTS: Evidence of allelic association was found with polymorphisms of SNAI1; in particular, the rs16995010-G allele was undertransmitted to the nsCL/P cases [P = 0.004, odds ratio = 0.69 (95% C.I. 0.54-0.89)]. However, the adjusted significance value corrected for all the performed tests was P = 0.051. CONCLUSIONS: The findings emerging by the present study suggest for the first time an involvement of SNAI1 in the nsCL/P onset. CLINICAL RELEVANCE: Interestingly, SNAI1 is known to promote epithelial to mesenchymal transition by repressing E-cadherin expression, but it needs an intact PRC2 to act this function. Alterations of this process could contribute to the complex etiology of nsCL/P.

RESUMO

Autologous fat grafting and methods of purification of harvested tissue have become one of the most current themes in regenerative medicine. The aim of this study was to evaluate the in vitro regenerative potential of abdomen lipoaspirates subjected to a combined washing-decantation purifying procedure, the Lull pgm System (Lull). Blood cells and stromal-vascular fraction (SVF) cells contained in the aspirates were investigated and compared with those obtained through more conventional fat-processing methods, that is, the decantation and Coleman's centrifugation techniques. The lowest number of erythrocytes, which are proinflammatory cells, was observed in the Lull samples, corresponding to about 50% of those isolated by decantation and centrifugation. The highest amount of SVF cells were isolated from the Lull samples whose number of colony forming units, representative of the amount of adipose-derived stem cells (ADSCs), was about fourfold and sixfold higher than in the decantation and centrifugation samples, respectively. Adipocyte and osteoblast commitment of SVF cells obtained from all the three procedures also confirmed that the subpopulation of ADSCs was actively represented in the processed aspirates. Moreover, the growth rate of the SVF cells was more accentuated in the samples obtained from decantation and Lull than centrifugation. In conclusion, Lull seems to be the best processing technique for adipose tissue graft with respect to decantation and centrifugation, because it clears more efficiently the fat from proinflammatory blood cells and provides the greatest number of proliferating SFV cells and ADSCs.

RESUMO

BACKGROUND: Eumorphic Plastic Surgery aims at improving the severe psychosocial pain caused by a deformity. Dysmorphopathology is an increasingly relevant problem facing the plastic surgeon. OBJECTIVE: The aim of this study is to describe the perioperative questionnaires created by the senior author and to present a cohort of plastic surgery patients suffering from dysmorphopathies. These patients were prospectively followed and evaluated with the proposed questionnaires through their surgical pathway to explore the degree of satisfaction or disappointment compared to expectations. METHODS: All candidates for plastic surgery procedures between April 2011 and June 2013 were included in the study. Preoperatively, all patients completed the Patient Expectation Questionnaire (E-pgm). Twelve months postoperatively, they completed the Patient Satisfaction Questionnaire (S-pgm). The E-pgm and S-pgm were compared to evaluate the consistency between the patient's preoperative expectations and postoperative evaluations. RESULTS: A total of 158 patients were included in the study. Out of them, 79 % experienced an improvement or no variation between preoperative expectations and postoperative satisfaction. With regard to the motivation for undergoing surgery, 91 % showed that the surgical procedure met the motivation. An overall positive perioperative change in life was experienced by 93 % of patients. CONCLUSIONS: The E-pgm questionnaire proved to be a valid and reliable tool for the selection of suitable candidates for surgery and for identification of dysmorphophobic patients. Enhancing the doctor-patient relationship and communication can reduce ambiguity and avoid troublesome misunderstandings, litigation and other legal implications.

RESUMO

BACKGROUND: Obesity is increasingly frequent in our society and is associated closely with metabolic disorders. As some studies have suggested, removal of fat tissue through liposuction and dermolipectomies may be of some benefit in the improvement of metabolic indices. This article aimed to review the published literature on this topic and to evaluate metabolic variations meta-analytically after liposuction, dermolipectomy, or both. METHODS: Through a literature search with the PubMed/Medline database, 14 studies were identified. All articles were analyzed, and several metabolic variables were chosen in the attempt to meta-analyze the effect of adipose tissue removal through the various studies. All statistical calculations were performed with Review Manager (RevMan), version 5.0. RESULTS: Several cardiovascular and metabolic variables are described as prone to variations after body-contouring procedures when a significant amount of adipose tissue has been excised. Four of the studies included in the analysis reported improvements in all the parameters examined. Seven articles showed improvement in some variables and no improvement in others, whereas three studies showed no beneficial variation in any of the considered indicators after body-contouring procedures. Fasting plasma insulin was identified as the only variable for which a meta-analysis of five included studies was possible. The meta-analysis showed a statistically significant reduction in fasting plasma insulin resulting from large-volume liposuction in obese healthy women. CONCLUSION: Many beneficial metabolic effects resulting from dermolipectomy and liposuction procedures are described in the literature. In particular, fasting plasma insulin and thus insulin sensitivity seem to be positively influenced. Further research, including prospective clinical studies, is necessary for better exploration of the effects that body-contouring plastic surgery procedures have on metabolic parameters.

RESUMO

Adipose-derived stem cells (ASC) are usually isolated from lipoaspirates, but it is not known if the anesthetic solution injected into adipose tissue affects cell yield and functions. Two different samples were drawn from the abdominal region of female subjects. In the first, a physiological solution containing lidocaine/adrenaline was injected (wet liposuction, WL), while in the contralateral area, the sample was collected without injecting any solution (dry liposuction, DL). The aspirates were processed to investigate the yield of the stromal-vascular fraction (SVF) cells and ASC frequency, growth rate, apoptosis, and differentiation potential. The solid dried mass of fresh WL isolates was lower than that of DL isolates (p < 0.01) due to the presence, in the former, of a liquid solution. As a consequence, the amount of WL-SVF cells was 18.7% lower than those obtained from DL (p < 0.01); this difference was also observed under culture conditions. In addition, the number of colony-forming unit-fibroblasts (CFU-Fs) obtained from 1 × 10(3) SVF cells was 25.5% lower in WL-aspirates than DL-aspirates (p < 0.05) owing, at least in part, to the observed presence of ASC [corrected] in the liquid solution of the WL isolates. After WL and DL, no differences were observed in ASC growth rate, apoptosis, or differentiation potential toward adipogenic, osteogenic, and endothelial cell lineages. In conclusion, WL yields about 40% fewer ASC than DL due to the combined effect of tissue dilution and the reduced frequency of ASC in the SVF. The main biological features of ASC are suitable for cell-based therapies.

RESUMO

Testosterone administration in female-to-male transsexual subjects aims to develop and maintain the characteristics of the desired sex. Very little data exists on its effects on sexuality of female-to-male transsexuals. The aim of this study was to evaluate sexual function and mood of female-to-male transsexuals from their first visit, throughout testosterone administration and after sex reassignment surgery. Participants were 50 female-to-male transsexual subjects who completed questionnaires assessing sexual parameters and mood. The authors measured reproductive hormones and hematological parameters. The results suggest a positive effect of testosterone treatment on sexual function and mood in female-to-male transsexual subjects.

RESUMO

Type-2 Familial Partial Lipodystrophy (FPLD2), a rare lipodystrophy caused by LMNA mutations, is characterized by a loss of subcutaneous fat from the trunk and limbs and excess accumulation of adipose tissue in the neck and face. Several studies have reported that the mineralocorticoid receptor (MR) plays an essential role in adipose tissue differentiation and functionality. We previously showed that brown preadipocytes isolated from a FPLD2 patient's neck aberrantly differentiate towards the white lineage. As this condition may be related to MR activation, we suspected altered MR dynamics in FPLD2. Despite cytoplasmic MR localization in control brown adipocytes, retention of MR was observed in FPLD2 brown adipocyte nuclei. Moreover, overexpression of wild-type or mutated prelamin A caused GFP-MR recruitment to the nuclear envelope in HEK293 cells, while drug-induced prelamin A co-localized with endogenous MR in human preadipocytes. Based on in silico analysis and in situ protein ligation assays, we could suggest an interaction between prelamin A and MR, which appears to be inhibited by mineralocorticoid receptor antagonism. Importantly, the MR antagonist spironolactone redirected FPLD2 preadipocyte differentiation towards the brown lineage, avoiding the formation of enlarged and dysmorphic lipid droplets. Finally, beneficial effects on brown adipose tissue activity were observed in an FPLD2 patient undergoing spironolactone treatment. These findings identify MR as a new lamin A interactor and a new player in lamin A-linked lipodystrophies.

RESUMO

The treatment of complex wounds often requires multiple surgical debridement and eventually reconstruction with skin grafts or flaps, under local or general anesthesia. When the patient's general conditions contraindicate surgical procedures, topical negative pressure with vacuum assisted closure (VAC)) device can achieve wound healing with reduction of healing time and simpler management. We treated with VAC device four patients with complex wounds and important contraindications to surgery. In all the patients, we used VAC device with common protocol of topical negative pressure. The healing was obtained in a period variable between 18 and 40 days; the results were satisfactory in three cases, one patient developed an aesthetically unpleasant scar. We present our experience to propose VAC when surgical procedures are contraindicated.

RESUMO

Non-syndromic cleft lip with or without cleft palate (NSCLP) is a malformation with variable phenotypes, resulting from a mixture of genetic and environmental factors. Some studies have supported a role for the 16q24 region and its candidate gene, CRISPLD2, in clefting. A replication study is necessary to confirm these findings. The aim of the present study was to test, by genetic linkage and association analyses, whether the candidate gene, CRISPLD2, represents a risk factor for NSCLP. The analysis of 39 multigenerational families provided formal exclusion of a linkage between NSCLP and the CRISPLD2 locus under different genetic models and non-parametric analyses. The family-based study of 239 unrelated probands and their parents revealed no association between any particular allele or haplotype and NSCLP. Therefore, the present investigation did not support the hypothesis of the involvement of CRISPLD2 in NSCLP malformation, at least with regard to the Italian population.

RESUMO

Orofacial clefts have a multifactorial aetiology encompassing both genetic and environmental components. While there is wide agreement on the importance of both genetic and nutritional factors, genetic influence in particular has not been well defined. As genetic variants in folate and homocysteine metabolism have been reported to influence the risk of orofacial clefts, an Italian cleft lip with or without cleft palate (CL/P) data set was enrolled for an analysis based on family association to test betaine-homocysteine methyltransferase (BHMT and BHMT2) and cystathionine beta-synthase (CBS) variants. No significant level of association was found between BHMT and BHMT2 variants, while evidence of an allelic association with CL/P was found for the single nucleotide polymorphism rs4920037, mapping at the CBS gene. A log-linear approach indicated that the best genetic model takes into account both mother and child genotypes. This suggests that human orofacial development is influenced by CBS genotypes that possibly operate through intergenerational fetal-maternal interaction.
