The neglected emotional drawbacks of the prioritization of embryos to transfer. Reprod Biomed Online 2024; 48:103621. [PMID: 38040621 DOI: 10.1016/j.rbmo.2023.103621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 10/11/2023] [Indexed: 12/03/2023]
Abstract
In recent years, increasing efforts have been made to develop advanced techniques that could predict the potential of implantation of each single embryo and prioritize the transfer of those at higher chance. The most promising include non-invasive preimplantation genetic testing for aneuploidy and artificial intelligence-based algorithms using time lapse images. The psychological effect of these add-ons is neglected. One could speculate that embarking on another transfer after one or more failures with the prospect of receiving an embryo of lower potential may be distressing for the couple. In addition, the symbolic and mental representation of an embryo with 'lower capacity to implant' is currently unknown but could affect couples' choices and wellbeing. These emotional responses may also undermine adherence to the programme and, ultimately, its real effectiveness. Future trials aimed at evaluating the validity of prioritization procedures must also consider the emotional burden on the couples.

Abstract
Sexual violence is a widespread phenomenon, as it has been estimated that about 35.6% of women have experienced some forms of sexual abuse, with variable prevalence estimates worldwide. Sexual violence has remarkable negative consequences on women's health and quality of life, with a specific harmful impact on women's psychological well-being and sexuality. In this narrative review, we provide an overview on the phenomenon of sexual violence against adult women and adolescents, discussing its associated multiple negative consequences with a specific focus on clinical and sexological aspects. ''Women centered care'' and a multidisciplinary approach appear of pivotal importance when working with sexual violence survivors. Woman should be engaged in all the clinical activities as equal partners in the decision-making process, and should be supported by multiple and different professional figures (i.e. gynecologists, psychologists, sexologists, forensic medical doctors, lawyers) working within the framework of a cooperative integrated model.

Evaluation of COVID-19 impact on DELAYing diagnostic-therapeutic pathways of lung cancer patients in Italy (COVID-DELAY study): fewer cases and higher stages from a real-world scenario. ESMO Open 2022; 7:100406. [PMID: 35219245 PMCID: PMC8810307 DOI: 10.1016/j.esmoop.2022.100406] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 01/19/2022] [Accepted: 01/23/2022] [Indexed: 12/18/2022] Open
Abstract
Introduction COVID-19 has disrupted the global health care system since March 2020. Lung cancer (LC) patients (pts) represent a vulnerable population highly affected by the pandemic. This multicenter Italian study aimed to evaluate whether the COVID-19 outbreak had an impact on access to cancer diagnosis and treatment of LC pts compared with pre-pandemic time. Methods Consecutive newly diagnosed LC pts referred to 25 Italian Oncology Departments between March and December 2020 were included. Access rate and temporal intervals between date of symptoms onset and diagnostic and therapeutic services were compared with the same period in 2019. Differences between the 2 years were analyzed using the chi-square test for categorical variables and the Mann–Whitney U test for continuous variables. Results A slight reduction (−6.9%) in newly diagnosed LC cases was observed in 2020 compared with 2019 (1523 versus 1637, P = 0.09). Newly diagnosed LC pts in 2020 were more likely to be diagnosed with stage IV disease (P < 0.01) and to be current smokers (someone who has smoked more than 100 cigarettes, including hand-rolled cigarettes, cigars, cigarillos, in their lifetime and has smoked in the last 28 days) (P < 0.01). The drop in terms of new diagnoses was greater in the lockdown period (percentage drop −12% versus −3.2%) compared with the other months included. More LC pts were referred to a low/medium volume hospital in 2020 compared with 2019 (P = 0.01). No differences emerged in terms of interval between symptoms onset and radiological diagnosis (P = 0.94), symptoms onset and cytohistological diagnosis (P = 0.92), symptoms onset and treatment start (P = 0.40), and treatment start and first radiological revaluation (P = 0.36). Conclusions Our study pointed out a reduction of new diagnoses with a shift towards higher stage at diagnosis for LC pts in 2020. Despite this, the measures adopted by Italian Oncology Departments ensured the maintenance of the diagnostic-therapeutic pathways of LC pts. The COVID-19 outbreak had an impact on access to lung cancer (LC) diagnosis and treatment. A slight reduction (−6.9%) in newly diagnosed LC cases was observed in 2020 compared with 2019. Newly diagnosed LC pts in 2020 were more likely to be diagnosed with stage IV disease. The Italian Oncology Departments ensured the maintenance of the diagnostic-therapeutic pathways of LC pts. A reverse migration from high-volume to low-volume cancer centers was noted during the pandemic.

Assessment of the knowledge level and experience of healthcare personnel concerning CPR and early defibrillation: an internal survey. BMC Cardiovasc Disord 2021; 21:195. [PMID: 33879072 PMCID: PMC8056553 DOI: 10.1186/s12872-021-02009-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Accepted: 04/12/2021] [Indexed: 11/24/2022] Open
Abstract
Background In‐hospital cardiac arrest (IHCA) is a major public health problem with significant mortality. Rapid cardiopulmonary resuscitation and early defibrillation is extremely connected to patient outcome. In this study, we aimed to assess the effects of a basic life support and defibrillation course in improving knowledge in IHCA management. Methods We performed a prospective observational study recruiting healthcare personnel working at Azienda Ospedaliero Universitaria Pisana, Pisa, Italy. Study consisted in the administration of two questionnaires before and after BLS-D course. The course was structured as an informative meeting and it was held according to European Resuscitation Council guidelines. Results 78 participants completed pre- and post-course questionnaires. Only 31.9% of the participants had taken part in a BLS-D before our study. After the course, we found a significative increase in the percentage of participants that evaluated their skills adequate in IHCA management (17.9% vs 42.3%; p < 0.01) and in the correct use of defibrillator (38.8% vs 67.9% p < 0.001). However, 51.3% of respondents still consider their preparation not entirely appropriate after the course. Even more, we observed a significant increase in the number of corrected responses after the course, especially about sequence performed in case of absent vital sign, CPR maneuvers and use of defibrillator. Conclusions The training course resulted in significant increase in the level of knowledge about the general management of IHCA in hospital staff. Therefore, a simple intervention such as an informative meetings improved significantly the knowledge about IHCA and, consequently, can lead to a reduction of morbidity and mortality.

Abstract
the SARS-CoV-2 pandemic started in December 2019 and still remains a major global health issue. Every country in the world has adopted drastic measures to contain the virus, although their stringency varies among countries, ranging from increased surveillance and focused interventions to strict lockdown (1). Italy was the second country where the disease had a major impact early in the pandemic, such that a strict nationwide lockdown was declared from March 9 to May 3, 2020. Nonetheless, between January and May 2020, there were 210,000 COVID-19 cases in Italy and 29,000 deaths were recorded (2). Due to the lockdown, universities (and in general all educational services) shifted to online classes, with students attending lessons and taking their exams from home. On-site activities were reduced to those considered indispensable. Research activities also had to be modified, such as by the adoption of a smart-working model (3). Between May and August 2020, the number of SARS-CoV-2 infections in Italy decreased. In response, the lockdown was loosened and some activities were restarted, albeit with specific safety protocols (social distancing, use of masks, temperature checks at the workplace entry, environmental disinfection, mixed models of smart and in-office work). These actions were accompanied by periodic serological and PCR screening tests (4).

How the harm of drugs and their availability affect brain reactions to drug cues: a meta-analysis of 64 neuroimaging activation studies. Transl Psychiatry 2020; 10:429. [PMID: 33318467 PMCID: PMC7736294 DOI: 10.1038/s41398-020-01115-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 11/06/2020] [Accepted: 11/18/2020] [Indexed: 01/02/2023] Open
Abstract
Visual drug cues are powerful triggers of craving in drug abusers contributing to enduring addiction. According to previous qualitative reviews, the response of the orbitofrontal cortex to such cues is sensitive to whether subjects are seeking treatment. Here we re-evaluate this proposal and assessed whether the nature of the drug matters. To this end, we performed a quantitative meta-analysis of 64 neuroimaging studies on drug-cue reactivity across legal (nicotine, alcohol) or illegal substances (cocaine, heroin). We used the ALE algorithm and a hierarchical clustering analysis followed by a cluster composition statistical analysis to assess the association of brain clusters with the nature of the substance, treatment status, and their interaction. Visual drug cues activate the mesocorticolimbic system and more so in abusers of illegal substances, suggesting that the illegal substances considered induce a deeper sensitization of the reward circuitry. Treatment status had a different modulatory role for legal and illegal substance abusers in anterior cingulate and orbitofrontal areas involved in inter-temporal decision making. The class of the substance and the treatment status are crucial and interacting factors that modulate the neural reactivity to drug cues. The orbitofrontal cortex is not sensitive to the treatment status per se, rather to the interaction of these factors. We discuss that these varying effects might be mediated by internal predispositions such as the intention to quit from drugs and external contingencies such as the daily life environmental availability of the drugs, the ease of getting them and the time frame of potential reward through drug consumption.

Abstract
The COVID-19 pandemic demands a reassessment of head and neck oncology treatment paradigms by posing several challenges for oncology services, with unprecedented pressure on the regional health care system. Since February 2020 this has severely disrupted health-care services, leading to accumulating clinic caseload and substantial delays for operations. The head and neck cancer services have been faced with the difficult task of managing the balance between infection risk to health-care providers and the risk of disease progression from prolonged waiting times. Herein, we share our experience in Firenze (Italy) and propose our action plan on the management of head and neck cancer services via multi-institution collaboration.

Abstract
Abstract
Surveillance of Adverse Events Following Immunization (AEFIs) is a crucial part of vaccination strategies because the most important concern of “No-vax group” is the safety of vaccination. According to UE laws, in Italy a passive surveillance system of AEFIs is established by law and managed by National Drug Authority (AIFA) and Regional Health Governments. The performance of surveillance system is different in the 21 Italian Regions and in some Region, such as Puglia, the AEFIs reporting rate has been, for several years, lower than National figure. The implementation of AEFIs active surveillance projects could increase the performance of AEFIs surveillance system, also after the end of the project.
In Puglia, since 2017, May to 2018, November, an active surveillance of AEFIs has been established, focused on MMRV vaccine. In this study, we analysed the AEFIs general picture in Puglia in 2016 and 2019, before and after active surveillance project. The source of data is the AIFA database; data were reported as number of AEFI and rate for Puglia population (reporting rate RR). The AEFIs were classified as serious, not serious and unclassifiable and causality assessment was performed according to WHO recommendations.
The number of AEFIs detected by the passive surveillance system is 91 for 2016 (RR 2,2 per 100.000 people), and 168 for 2019 (RR 4,2 per 100.000 people). The percentage of serious AEFIs was 23.1% (21/91) in 2016 and 31% (52/168) in 2019 and unclassifiable AEFIs were 22% (20/91) in 2016 and 0 in 2019. The percentage of serious AEFIs for which the result of causality assessment was “consistent” is 23,8% (5/21) in 2016 and 55,8% (29/52) in 2019.
The experience of AEFIs active surveillance project increase the performance of AEFIs surveillance system. From 2016 (pre-project time) to 2019 (post-project time) the number of AEFIs detected was doubled, the number of unclassifiable AEFIs (proxy of poor reliability of the system) was reduced to zero.
Key messages
AEFIs passive surveillance system could be affected by underreporting and lack of quality. The AEFIs active surveillance project are an important occasion of traineeship for vaccinovigilance system, that could increase the sensibility and the reliability.

Abstract
Maxillofacial departments in 23 surgical units in Italy have been increasingly involved in facing the COVID-19 emergency. Elective surgeries have been progressively postponed to free up beds and offer human and material resources to those infected. We compiled an inventory of 32 questions to evaluate the impact of the SARS-COV2 epidemic on maxillofacial surgery in 23 selected Italian maxillofacial departments. The questionnaire focused on three different aspects: the variation of the workload, showing both a reduction of the number of team members (-16% among specialists, -11% among residents) due to reallocation or contamination and a consistent reduction of elective activities (the number of outpatient visits cancelled during the first month of the COVID-19 epidemic was about 10 000 all over Italy), while only tumour surgery and trauma surgery has been widely guaranteed; the screening procedures on patients and physicians (22% of maxillofacial units found infected surgeons, which is 4% of all maxillofacial surgeons); and the availability of Personal Protective Equipment, is only considered to be partial in 48% of Maxillofacial departments. This emergency has forced those of us in the Italian health system to change the way we work, but only time will prove if these changes have been effective.

Abstract
BACKGROUND The purpose of the present study was to assess the safety and efficacy of both functional intranasal procedures and cosmetic rhinoplasty combined with bimaxillary surgery. METHODS The author executed a retrospective cohort study derived from patients who underwent combined rhinoseptoplasty and bimaxillary surgery at a private practice setting (Face Surgery Center, Parma, Italy) between April 2006 and 2015 by a single surgeon. The minimum follow-up was 12 months. Patients underwent bimaxillary orthognathic surgery, functional nasal surgery and cosmetic rhinoplasty. RESULTS Two-hundred and fifty (250) consecutive, non-randomized patients met the inclusion criteria to enter the study. The overall complication rate was 5%, whereas the revision rate was 9%, showing an overall low rate, comparable to that of primary rhinoplasty (control group). About 94% of the patients polled after this procedure asserted they definitely accepted to have rhinoplasty only because it was included in one single surgical act together with orthognathic surgery. CONCLUSION Cosmetic rhinoplasty shows great potentials to change our patients' appearance, whereas orthognathic surgery corrects jaw skeletal deformities and builds the right foundation for facial harmony. The combination of both procedures magnifies the single results reciprocally and significantly enhances the final outcomes. The quality of the overall aesthetic results, the scarcity of complications and the low percentage of defects that require revisions lead to the conclusion that when alterations to both the jaws and the nose are detected, a single intervention can grant great benefit to the patients in terms of morbidity and costs.

Wronger than wrong: Graded mapping of the errors of an avatar in the performance monitoring system of the onlooker. Neuroimage 2017; 167:1-10.

Abstract
EEG studies show that observing errors in one's own or others' actions triggers specific electro-cortical signatures in the onlooker's brain, but whether the brain error-monitoring system operates according to graded or discrete rules is still largely unknown. To explore this issue, we combined immersive virtual reality with EEG recording in participants who observed an avatar reaching-to-grasp a glass from a first-person perspective. The avatar could perform correct or erroneous actions. Erroneous grasps were defined as small or large depending on the magnitude of the trajectory deviation from the to-be-grasped glass. Results show that electro-cortical indices of error detection (indexed by ERN and mid-frontal theta oscillations), but not those of error awareness (indexed by error-Positivity), were gradually modulated by the magnitude of the observed errors. Moreover, the phase connectivity analysis revealed that enhancement of mid-frontal theta phase synchronization paralleled the magnitude of the observed error. Thus, theta oscillations represent an electro-cortical index of the degree of control exerted by mid-frontal regions whose activation depends on how much an observed action outcome results maladaptive for the onlooker. Our study provides novel neurophysiological evidence that the error monitoring system maps observed errors of different magnitude according to fine-grain, graded rather than all-or-none rules.

Abstract
AIMS This review evaluates those main risk factors that can affect patients undergoing thyroidectomy, to reach a better pre- and post-operative management of transient and permanent hypoparathyroidism. DISCUSSION The transient hypoparathyroidism is a potentially severe complication of thyroidectomy, including a wide range of signs and symptoms that persists for a few weeks. The definitive hypoparathyroidism occurs when a medical treatment is necessary over 12 months. Risk factors that may influence the onset of this condition after thyroidectomy include: pre- and post-operative biochemical factors, such as serum calcium levels, vitamin D blood concentrations and intact PTH. Other involved factors could be summarized as follow: female sex, Graves' or thyroid neoplastic diseases, surgeon's dexterity and surgical technique. The medical treatment includes the administration of calcium, vitamin D and magnesium sometimes. CONCLUSIONS Although biological and biochemical factors could be related to iatrogenic hypoparathyroidism, the surgeon's experience and the used surgical technique still maintain a crucial role in the aetiology of this important complication.

Abstract
INTRODUCTION Hyperparathyroidism is an alteration of the pathophysiological parathyroid hormone (PTH) secretion due or an independent and abnormal release (primary or tertiary hyperparathyroidism) by the parathyroid or an alteration of calcium homeostasis that stimulates the excessive production of parathyroid hormone (secondary hyperparathyroidism). AIMS There is not a standard, clinical or surgical, treatment for hyperparathyroidism. We review current diagnostic and therapeutic methods. DISCUSSION In secondary hyperparathyroidism (2HPT) there is a progressive hyperplasia of the parathyroid glands and an increased production of parathyroid hormone. Several causes are proposed: chronic renal insufficiency, vitamin D deficiency, malabsorption syndrome. The tertiary hyperparathyroidism (3HPT) is considered a state of excessive autonomous secretion of PTH due to long-standing 2HPT and it's usually the result of a lack of suppression in the production of PTH. The pathophysiological implications are both skeletal and extraskeletal: it damages the cardiovascular system, nervous system, immune, hematopoietic and endocrine system. The introduction of new drugs has improved the survival of these patients, allowing the inhibition of the synthesis of PTH. Indication for surgical treatment is unresponsive medical therapy. CONCLUSIONS There are no large prospective studies that comparing the medical and surgical treatment. The choice is not unique and we have to consider the singolar case and the clinical condition of the patient.

Abstract
Epithelial to Mesenchymal Transition (EMT) is an important process involved in cancer, embryogenesis and organ development. Its role in nonsyndromic cleft lip with or without cleft palate (NSCL/P) has been extensively investigated and successfully linked to the disease. In this study, we focused on a gene, CDH1, encoding for E-cadherin, a key protein in EMT. We carried out an association study on an Italian sample group, genotyping four single nucleotide variations within the CDH1 gene, in order to verify the potential role of this gene in NSCL/P etiology. Neither the haplotype nor the family-based association test revealed any association between the genotyped SNPs and the pathology. Our results demonstrate that, in our Italian sample study, the analyzed single nucleotide polymorphisms are not associated to NSCL/P.

Abstract
Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. Conventional surgical approaches include the coronal flap, direct cutaneous incision, and endoscopic techniques. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. The medical records and radiological findings of all patients who underwent surgical treatment for anterior frontal sinus fractures from January 2009 to December 2013 at the study hospital in Florence, Italy, were reviewed. The final study sample consisted of 15 patients (13 males and two females) with isolated anterior frontal sinus fractures who were treated with closed reduction using percutaneous screws. The mean age was 32.1 years. The skin incisions healed without any visible scarring, and no depressions of the frontal sinuses were evident in the postoperative period. Computed tomography scans performed at 6 months postoperatively showed adequate reduction of the displaced fragments. This closed technique is a good option for displaced isolated fractures of the anterior frontal sinus. However, the technique is not adequate for complex fractures of the frontal sinus.

Abstract
BACKGROUND Patients who underwent primary inguinal hernia repair still report a high rate of postoperative pain after operation due to the effect of mesh fixation by suture.An alternative is the use of human fibrin glue. We compared the two techniques. METHODS 468 patients randomly underwent primary inguinal hernia Lichtenstein repair fixing the mesh by suture or by human fibrin glue (HFG); in both cases the mesh was fixed to the posterior wall of the inguinal canal and to the inguinal ligament. RESULTS No significant differences were recorded between the two groups in terms of complications, while the sutureless technique reduces the operative time and the postoperative pain. CONCLUSIONS A widespread technique for the treatment of inguinal hernia is the application of a mesh using Lichtenstein procedure. The prosthesis can be fixed by traditional suture or using a new method of sutureless fixation with adhesive materials that shows an excellent local tolerability and lack of adverse effects and contraindications.

Abstract
Inflammatory bowel disease (IBD) consists of two distinct clinical forms, ulcerative colitis (UC) and Crohn's disease (CD), with unknown aetiology, which nevertheless are considered to share almost identical pathophysiological backgrounds. Up to date, a full coherent mechanistic explanation for IBD is still lacking, but people start to realize that the pathogenesis of IBD involves four fundamental components: the environment, gut microbiota, the immune system and the genome. As a consequence, IBD development might be due to an altered immune response and a disrupted mechanism of host tolerance to the non-pathogenic resident microbiota, leading to an elevated inflammatory response. Considering the available data arising from the scientific literature, here reviewed, in CD, a benefit of probiotics remains unproven; in UC, a benefit of probiotics remains unproven, even if E. coli Nissle 1917 seems promising in maintaining remission and it could be considered an alternative in patients intolerant or resistant to 5-ASA preparations; in pouchitis, small controlled trials suggest a benefit from VSL no. 3 in the primary and secondary prevention of pouchitis; in IBD-associated conditions, a benefit of probiotics remains unproven. However, well-designed randomized control clinical trials are necessary to understand the undoubted role of these agents in the management of gut physiology in health and disease.

Abstract
Marginal donors represent a poorly utilized source of organs for transplantation despite their availability. The key is to reduce the ischemic damage in the effort to improve organ quality. This study investigated the histologic effects after in situ perfusion of preservation with a two-layer method compared with the classic University of Wisconsin preservation in term of tissue integrity and number of viable exocrine cells in the rat pancreas both after exsanguination and at 8 weeks of cryopreservation. Pancreata harvested from 60 rats were collected using 3 methods: two-layer method following University of Wisconsin perfusion; exsanguination; and classic University of Wisconsin perfusion/storage. In addition to histologic analysis of collected pancreata, we analyzed the number of CK19(+) cells and their viability using chi-square tests with values P < .05 considered to be significant. Rat pancreas histology showed as University of Wisconsin in situ perfusion and preservation by the two-layer method to be more effective to maintain the morphologic integrity of both exocrine and endocrine tissues. There were a larger number of CK19(+) cells with good viability. Moreover, the effects of oxygenation were visible in pancreas biopsies preserved after exsanguination. In situ University of Wisconsin perfusion and preservation for 240 minutes with the two-layer method yielded greater numbers and viability of CK19(+) cells even after 8 weeks of cryopreservation.

Abstract
True smooth muscle neoplasms of the wall of digestive tract are rare, in particular in the stomach, and the benign ones are prevalent. We report a case of gastric leiomyosarcoma (LMS) that we observed, diagnosed to a 71 years-old man, with important comorbidities, who had already underwent the amputation of the right lower limb. In consequence of the discovery of anaemia and melaena he underwent an endoscopy of the upper GI tract and CT scan, which showed the presence of a neoformation of the gastric wall, but because of the thrombosis of the common iliac artery and the occurrence of the clinical picture of critical ischaemia, at first the patient underwent the amputation of the left lower limb e only then an intervention of atypical gastroresection. Despite the neoplastic infiltration of the resection margins and the impossibility to undertake an adjuvant chemotherapy, the follow-up at 6, 12 and 28 months did not show a recurrence of the disease that remained in phase of clinical remission.

Abstract
Among the complications of internal jugular vein insertion there is the lesion of the cervical sympathetic trunk with the onset of Bernard-Horner syndrome, consisting of miosis, eyelid ptosis, enophthalmos and anhidrosis on the same side of the lesion. The neurological damage can be caused by the direct puncture of the trunk or by the irritating and compressive action of a hematoma during the puncture of the internal jugular; the clinical picture, when reversible, resolves in a few months. The case we report is about the onset of the syndrome after accidental puncture of carotid artery, followed by the total disappearance of signs in a few days.

Abstract
A 50 years-old man developed 24 hours after hemorrhoidectomy a severe Fournier's gangrene of the scrotum necessitating surgical exeresis of more than 2/3 of scrotal skin followed by hyperbaric oxygen therapy. After the resolution of the septic phase, scrotum reconstruction was obtained by tissue expansion to avoid more invasive advanced reconstructive techniques. The procedure consisted of an enzymatic and mechanical debridement and progressive skin expansion by package of gauzes of increasing volume covered with a collagenasecloramphenicol ointment (Iruxol®- Smith and Nephew, Italy), then closing the wound edges by temporary stitches to put under tension the skin. The reestablishment of the natural elasticity of the scrotal skin was obtained in ten days and at the final closure of the wound edges an acceptable optimal aesthetic result was achieved.

Abstract
β- and γ-catenin are components of catenin family involved in cadherin adhesion function. Recently it has been shown that this family is involved in other functions such as signaling and activation of transcription factors. The final goal of this study was to evaluate the role of β- and γ-catenin in bone cell physiology and bone regeneration. Formalin-fixed-paraffin embedded specimens of 15 human bone specimens after sinus lift were collected and examined by immunohistochemstry using primary antibodies against β- and γ-catenin. Staining intensity and cellular localization were evaluated. β and γ-catenin showed a very high level of expression in human bone tissues. In particular catenins were expressed in cells with morphological findings of osteoblasts in the areas of new bone formation at the junction between mineralized and unmineralized tissue, between osteoid matrix and bone. Osteoclasts showed also positivity for catenins. Osteocytes, cells located in lacunae of mature mineralized bone with function of bone vitality maintenance, showed no expression for catenins. Specimens characterized by high amount of catenins in osteoblasts at 1° month showed high grade of bone maturation at 3° month. Data demonstrated an overall involvement of catenins in human bone tissues and in particular during bone regeneration process. The presence of staining for β- and γ-catenin particularly in osteoblasts demonstrates a significant role of catenins in functions, other than in cadherin interaction, such as signaling and activation of transcription factors during differentiation of bone tissues.

Abstract
The purpose of this paper was to document the application to the split-crest mandibular procedure in two stage in order to avoid cortical resorption due to periosteal detachment in buccal cortical bone of the alveolar crest. Twenty-two healthy patients with non-contributory past medical history (14 women and 8 men, all non-smokers, mean age 59 years, range 54–65 years) were included in this study. After buccal mucoperiosteal flap was followed by a sagittal corticotomy in the coronal area of the alveolar crest and a second sagittal corticotomy, but in a lower (basal) position and two vertical corticotomies in the buccal wall, using a ultrasonic surgery device (Surgysonic, Esacrom, Imola Italy). Adequate crest expansion was achieved without compromising cortical vascularisation by utilising a combination of scalpel, thin chisels and threaded osteotomes (Bone System, Milano, Italy). Postoperative results were assessed by panoramic and periapical radiographs. Ossification of the osteotomy lines was evident and could be observed as sites with increasing radiopacity on panoramic and periapical radiographs 3 months after implants insertion. No dehiscence of the mucosa was observed. No patient suffered from hypoaesthesia. The mean horizontal bone increase in coronal area was 5±3 mm. Mandibular ridge expansion using a split-crest technique that included grafting the implant sites with a ultrasonic surgery device is a viable therapeutic alternative for implant placement in this patient population.

Abstract
Squamous cell carcinoma is the most frequent malignant tumor of the oral cavity. Markers of tumor progression that could help to define diagnosis, plan treatment and implement prognosis have still to be identified. Seven candidate markers for tumor progression were investigated using a loss of heterozygosity (LOH) assay. The sample was made up of 51 squamous cell carcinoma and adjacent normal tissues from the same patients. LOH at one, or more, markers was a relatively frequent event that was observed in 53% of tumors. The number of losses detected in each tumor was significantly associated with tumor severity. Significant association between UICC stage grouping and LOH was found for 3 gene loci: programmed cell death 4 (PDCD4), catenin beta 1 (CTNNB1), and caspase 4 (CASP4). No association between allelic loss and the occurrence of lymph node metastasis was found for any of the seven investigated loci. Overall, LOH contributes to tumor progression of oral SCC. A specific role for PDCD4, CTNNB1, and CASP4 was found.

Abstract
Direct visualization of the oral tissue autofluorescence has been recently reviewed in several studies as a possible adjunctive tool for early recognition and diagnosis of potentially malignant and malignant oral disorders. The aims of this study were to assess: a) the value of a simple handheld device for tissue auto-fluorescence visualization of potentially malignant oral lesions; and b) the sensitivity, specificity and diagnostic accuracy of tested device, using histological examination as the gold standard. 175 consecutive patients, with at least one clinical oral lesion, were enrolled in the study. Clinical conventional inspections were performed for each patient by two blind operators. Then, oral biopsy and histological examination were performed. Pathologist was blind with respect to the autofluorescence results. The 175 histological assessments revealed no dysplasia, mild dysplasia, moderate/severe dysplasia and OSCC, in the 67.4%, 8.6%, 8%, 16% of cases, respectively. Oral lesions diagnosed as OSCC were found as positive under fluorescent light in the 96.4% of cases. Statistically significant correlation was observed between oral dysplastic lesions and the loss of tissue fluorescence (p-value=0.001). Low sensitivity values (60% and 71%) were recorded about the ability of the device in differentiating mild dysplasia vs. lack of dysplasia and moderate/severe dysplasia vs absence of dysplasia, respectively. The device tested in our study was found to not replace the histopathology procedure. However, we assessed its usefulness for oral tissue examination, especially within an oral medicine secondary care facility, before performing a biopsy and in monitoring oral lesions.

Abstract
The 12q13 region has been suggested as a candidate locus for orofacial cleft by different investigators. In the present study we tested the region for linkage with non syndromic cleft lip with or without cleft palate in a collection of 39 Italian multigenerational families, using microsatellite markers. No evidence of linkage was detected between the marker map and NSCLP under different mode of inheritance nor with a nonparametric method. Formal level of linkage exclusion, were obtained for each point of the map. Genetic heterogeneity and the different impact of the candidate locus among populations could explain conflicting results obtained in different studies.

Abstract
Biological and technical failures of implants have already been reported. Mechanical factors are certainly of importance in implant failures, even if their exact nature has not yet been established. The abutment screw fracture or loosening represents a rare, but quite unpleasant failure. The aim of the present research is an analysis and structural examination of screw thread or abutment. In this study broken screws were excluded. A total of 58 screw thread loosening were observed, 5 Branemark, (Nobel Biocare, Gothenburg, Sweden) 4 Implant Innovation (Riverside Drive Palm Beach Gardens, FL, USA) and 7 Restore (Lifecore Biomedical, Chaska, Minnesota, USA) and 42 T.B.R. implant (Benax, Ancona, Italy). The loosened abutment screws were retrieved and analyzed under SEM. Many alterations and deformations were present in concavities and convexities of screw threads.

Abstract
BACKGROUND The "difficult" preparation of iliac vessels in the kidney transplant recipient caused by a perivascular fibrosis with satellite lymphadenopathy is sometimes burdened by post-transplant complications (lymphocele, seroma and hematoma). Both iliac vascular adhesions and satellite lymphoadenopaty are often due to reiterate femoral cannulation aimed to hemodialysis. PATIENTS AND METHODS The case report concerns a 60 years old female uremic patient, on dialysis for about 4 years with perivascular fibrosis and pelvic lymphadenopathy caused by bilateral femoral artery catheterization. In the course of kidney transplant, preparation of the iliac vessels was performed by ultrasonic scalpel. In the case we handled there was no incidence of immediate, medium and long term post operative complications, with a considerable reduction of the operative time in the vascular dissection performed without ligation. Often the long dialytic period, the same nephropathy, reiterative femoral catheterization determine perivascular fibrosis and/or consensual lymphadenopathy. In these cases, in light of initial experience, the use of ultrasonic scalpel enables easy dissection by the coagulative synthesis not only of vascular compartment but also of the lymphatic duct whose leakage, particularly in these cases, creates a favourable condition to hematoma and/or lymphocele formation. These complications, although rarely jeopardize patient's life, however, may affect the outcome of transplantation in terms of morbidity and survival of the organ. The use of ultrasonic scalpel ensures total control of vascular and lymphatic compartment coagulation, alongside a reduction in the time of surgical dissection.

Abstract
To describe our experience with ultrasonic-guided instillation of povidone-iodine to treat post-kidney transplantation lymphocele. Patients and methods. We studied the safety and efficacy of this procedure for treatment of lymphocele in 6 male kidney transplanted recipients in which we assisted a progressive increase of creatinine and urinary proteins levels and color-Doppler ultrasonography demonstrated an increase (25,4%) of index of resistence (IR) Using eco-colorDoppler, the related-graft lymphocele location and the distance to the anterior abdominal wall were determined; then, a radiopaque double-lumen catheter was used to instillate 5% povidone-iodine 10 ml. Results. Percutaneous drainage achieved a resolution rate of 100%. Studying the rate of peripheral and internal vascularization of the kidney before and after treatment, eco-colorDoppler showed a significant decrease of the IR (24,6%). Conclusions. The US-guided povidone-iodine instillation for treatment of lymphocele following renal transplantation may be considered as first choice therapy in such disease.

Abstract
The purpose of this work was to describe a clinical case with reduced vertical height in both the posterior sectors, due to maxillary dento-alveolar extrusion in mandibular edentulous space, as a result of some extractions which have not been promptly replaced by a prosthetic rehabilitation, eventually resolved with a bilateral posterior segmental maxillary osteotomy (PMSO). Our surgical technique was practised under general anesthesia according to Kufner's version of Schuchardt's original description. In the light of the present outcomes, in severe clinical cases of dento-alveolar extrusion, the PMSO can be considered the optimal solution, because of the quality and the stability of the final result, the short therapeutic times, the limited morbidity and the modest compliance asked to the patient.

Abstract
OBJECTIVE To analyze risk factors for type 2 diabetes among women attending menopause clinics in Italy for counselling about the menopause. SUBJECTS Women attending a network of first-level outpatient menopause clinics in Italy for general counselling about menopause or treatment of menopausal symptoms. METHODS Cross-sectional study with no exclusion criteria. Type 2 diabetes was defined according to National Diabetes Data Groups Indications and the fasting blood glucose at an oral glucose tolerance test within the previous year. RESULTS Out of the 44 694 considered in this analysis, 808 had a diagnosis of diabetes type 2 (1.8%). In comparison with women aged < 50 years, the multivariate odds ratios (OR) of type 2 diabetes were 1.31 (95% confidence interval (CI), 0.99-1.74) for women aged 50-52 years, 1.66 (95% CI, 1.27-2.17) at 53-56 years and 2.84 (95% CI, 2.20-3.67) in women aged > or = 57 years. Type 2 diabetes was less frequently reported in more educated women (OR high school/university vs. primary school = 0.44 (95% CI, 0.36-0.55)). Being overweight was associated with an increased risk of type 2 diabetes. In comparison with women reporting a low level of physical activity, the multivariate OR of type 2 diabetes was 0.67 (95% CI, 0.54-0.84) for women reporting regular physical activity. In comparison with premenopausal women, the multivariate OR of type 2 diabetes was 1.38 (95% CI, 1.03-1.84) in women with natural menopause. This finding was present also after allowing for the potential confounding effect of age. The multivariate OR of diabetes for users of hormonal replacement therapy was 0.58 (95% CI, 0.46-0.73). CONCLUSIONS This large cross-sectional study suggests that postmenopausal women are at higher risk of type 2 diabetes after allowance for the effect of age. Other main determinants of risk of type 2 diabetes in women around menopause were low socioeconomic status and being overweight. Diabetes was found less frequently in those taking hormone replacement therapy.

Abstract
OBJECTIVES Nonsyndromic cleft lip with or without cleft palate (CL/P) is a frequent craniofacial malformation with a complex aetiology. Since the first report of an association between DNA sequence variants at the transforming growth factor alpha gene (TGFA) and nonsyndromic oral clefts, several studies have been carried out, which have produced conflicting results. Overall, TGFA is considered as a genetic clefting modifier in humans. Murine models indicate that the Tgfa product (tgfalpha), as well as its receptor (Egfr), actively participates in palate development. Notably, Egfr null mice showed an increased incidence in orofacial clefts. In the present study, genes which code for subunits of epidermal growth factor receptors (EGFRs) have been considered as candidate genes for CL/P. METHODS A family based investigation was performed using a sample of 239 case/parent triads. The aim was to test for an allelic association between common non-synonymous polymorphisms in EGFR genes and CL/P. RESULTS AND CONCLUSION The results did not suggest any evidence of a link between the investigated polymorphisms and CL/P, however the involvement of different polymorphisms or mutations in such genes cannot be excluded.

Abstract
e15138 Background: Bevacizumab (BEV) has shown clinical activity in metastatic colorectal cancer patients (mCRC)and randomised phase III trials have demonstrated that this agent significantly improves overall and/or progression-free survival when added to first-line irinotecan based chemotherapy (CT) regimens. We evaluated the efficacy and safety of BEV plus FOLFIRI (irinotecan, 5- fluorouracil, and leucovorin) as first line treatment in 27 consecutive metastatic colorectal cancer cases, with the primary end point to calculate the median time to clinical response with this chemotherapeutic schedule. Methods: Between October 2007 and January 2008 we collected the data on 27 patients with mCRC treated with first line chemotherapy with BEV plus FOLFIRI. Elegibility criteria had to be: mCRC; no prior CT for metastatic disease; ECOG PS 0/1, adequate organ function; no CNS metastases. The treatment consisted of a minimum of six cycles of irinotecan plus infusional 5-FU/LV according to the classical FOLFIRI schedule; BEV (5mg/kg) was given on day 1 with CT and then every 2 weeks until disease progression. Safety and response were assessed at the time of first CT and every 4 weeks thereafter. Results: 27 pts were evaluable (male 18; median age 61 years (range 45–77), ECOG PS 0: 52%, PS 1: 48%. The sites of metastases were: liver (15 pts), lung (5 pts), liver and lung (5 pts), peritoneal wall (2 pts).Median follow-up was 18 weeks. Two patients had complete response(CR) and 13 pts partial response (PR), with an overall response rate of 57.7%. Five patients had stable disease and 6 patients showed progressive disease. A clinical benefit was demonstrated in 77 % of pts. We observed a median time to clinical response of 11 weeks, evaluated with tumor markers and with CT/NMR/US examinations. A grade 3 or 4 neutropenia was detected in 39% of pts and grade 2 or 3 hypertension in 9%. We did’nt observe cases of thrombosis, bleeding and gastrointestinal perforation, sometimes related to the use of BEV. Conclusions: In this little experience the efficacy and safety of BEV associated with FOLFIRI schedule, a first line therapy in mCRC,is consistent with results from other previous studies, showing moreover a short time to clinical response with this association. No significant financial relationships to disclose.

Abstract
Bioengineering skin represents a successful outcome in the interdisciplinary research applied to reconstructive surgery. In this study we report our experience in the reconstruction of a wide traumatic wound by autologous engineered skin, grown on a biomaterial scaffold. Advantages were rapid reparation of the trauma and good scars.

Abstract
Plexiform neurofibromas (PN) are one of the most common and severe types of neurofibroma that occur in neurofibromatosis type I. These tumours affect long portions of nerves, infiltrating the nerve and surrounding tissue thus causing significant pain, deformity and functional problems in the affected part of the body. Treatment of this variant of neurofibromas is currently surgical. The aim of this study was to analyze the surgical treatment of plexiform neurofibromas in the lower and upper extremities. The clinical pathological features of 29 neurofibromas, 12 in the upper extremities and 17 in the lower extremities, as diagnosed at the Department of Plastic and Reconstructive Surgery of University "La Sapienza" in Rome from 2000 to 2007, were reviewed. We established that subtotal and total resection without functional destruction is often possible for superficial PN.

The sea urchin embryo: a model to study Alzheimer's beta amyloid induced toxicity. Arch Biochem Biophys 2008; 483:120-6.

Abstract
Alzheimer's disease (AD) is the most common form of dementia. The cause of AD is closely related to the accumulation of amyloid beta peptide in the neuritic plaques. The use of animal model systems represents a good strategy to elucidate the molecular mechanism behind the development of this pathology. Here we use the Paracentrotus lividus embryo to identify molecules and pathways that can be involved in the degenerative process. As a first step, we identified the presence of an antigen related to the human APP, called PlAPP. This antigen, after gastrula stage, is processed producing a polypeptide of about 10kDa. By immunohistochemistry we localized the PlAPP antigen in some serotonin expressing cells. Similarly, after 48 or 96h incubation, a recombinant beta-amyloid peptide, rAbeta42, accumulates around the intestinal tube and oesophagus. In addition, incubation of sea urchin embryos with two different solutions rich in oligomers and fibrillar aggregates of rAbeta42 induce activation of apoptosis as detected by TUNEL assay. Moreover, we demonstrate that aggregates induce apoptosis by extrinsic pathway activation, whereas oligomers induce apoptosis both by extrinsic and intrinsic pathway activation. Utilizing an apoptotic inhibitor, caspases activation was offset and morphological damage rescued. Taken together all these observations suggest that the sea urchin may be a simple and suitable model to characterize the mechanism underlining the cytotoxicity of Abeta42.
