Abstract
Study question
Could microRNAs represent efficient biomarkers to evaluate male infertility and the tendency of develop testicular germ cell tumors (TGCTs)?
Summary answer
The up-regulation of miR-193a-5p, miR-93-5p and let-7c-5p in TGCT patients with impaired spermiogram could represent a molecular signature of male infertility related to TGCTs.
What is known already
Testicular germ cell tumors (TGCTs) are the most recurrent tumors in young men with the highest incidence between the ages of 20 and 40 years and represent more than 60% of all cancers diagnosed in this age range. Several studies have shown a correlation between TGCTs and infertility, not only because infertility could be a consequence of testicular damage due to TGCTs but also because infertility may represent a risk factor for TGCTs. Therefore, it is important to find valid biomarkers that could be used to specifically identify infertility related to an increased risk of developing TGCTs.
Study design, size, duration
From March 2021 to January 2023, we collected 44 seminal plasma samples: 17 from TGCT patients who were undergoing sperm cryopreservation prior to chemotherapy, 14 with impaired spermiogram (IS) and 3 with normal spermiogram (NS) and 27 from control patients, 16 with IS and 11 with NS, undergoing assisted fertilization techniques. We evaluated the potential role of miRNAs as non-invasive biomarkers, analyzing the differential expression of 84 miRNAs in relation to cancer, infertility and both.
Participants/materials, setting, methods
Semen samples were placed 30’/37 °C, seminal plasma was purified using density-gradient centrifugation and stored at -80 °C. RNA was purified by Qiagen miRNeasy Serum/Plasma Kit and analyzed by miRCURY LNA miRNA SYBR®Green PCR_SerumPlasma, 96-well plate. We applied the 2−ΔΔCT method and statistical significance was evaluated by Significance Analysis of Microarrays, screened by p-values ≤ 0.05. We performed a Pearson correlation analysis applying two-sided p-values. miRTarBASE, MIENTURNET and Cytoscape were used for bioinformatics analysis.
Main results and the role of chance
In the four comparisons, we found 9 differentially expressed microRNAs. In particular, miR-221-3p, miR-222-3p, miR-204-5p and miR-205-5p down regulation would appear to be related to infertility, regardless to the cancer. Conversely, all TGCT patients shown an up-regulation of miR-376c-3p. Interestingly, up-regulation of miR-193a-5p, miR-93-5p and let-7c-5p specifically discriminates the infertile cancer patients vs other categories. Moreover, these three miRNAs showed a significant positive correlation both in cancer patients with impaired spermiogram and in infertile controls. This correlation demonstrates that their expression changes in the same way in the single samples and strongly suggests their role as early biomarkers of TGCT patients with impaired spermiogram. From the KEGG pathway analysis has emerged that DE miRNAs are involved in several signaling pathway, such as MAPK, mTOR, p53, PI3K-Akt, AMPK, FoxO, JAK-STAT, Ras, Estrogen signaling pathways, as well as cell cycle and cellular senescence. Moreover, from the Diseases Ontology analysis we found than those miRNAs are involved in germ cell tumor, male reproductive organ cancer, prostate cancer, male infertility and azoospermia.
Limitations, reasons for caution
The data must be validated by single assays in higher number of samples. These experiments are currently ongoing.
Wider implications of the findings
Three of the DE miRNAs are overexpressed in TGCT with impaired spermiogram patients. Specifically, they are over-expressed in TGCT with impaired spermiogram compared to infertile controls, so they may represent specific biomarkers able to discriminate, among the young men with infertility, those with higher risk of develop testicular cancer.

Abstract
Omalizumab is a monoclonal anti-IgE antibody which is effective in chronic spontaneous urticaria (CSU), although clinical response appears to be variable in the real-life setting. The aim of this study was to evaluate whether the response of CSU to omalizumab and disease relapse are associated with individual and/or clinical characteristics of patients. We retrospectively evaluated the clinical records of 124 patients treated with omalizumab for moderate to severe CSU refractory to antihistamines. Disease activity was assessed using the urticaria activity score over the last 7 days (UAS7). After 24 weeks of treatment, 91% of patients showed complete remission (UAS7 = 0) or good control (UAS7 < 7) of CSU. Omalizumab was re-administered in 45 patients because of recurrence of moderate to severe symptoms at week 8 after treatment discontinuation or later, and clinical results achieved with retreatment were similar to those observed in the first course. Among the parameters included in our analysis (age and sex of patients, documented history of atopy or autoimmune thyroid disease, CSU duration and baseline severity, concurrent angioedema, and association with chronic inducible urticaria), none was associated with response to omalizumab in our study population. Similarly, these parameters did not significantly differ between patients who experienced CSU relapse and those without relapse. Predictors of response to omalizumab treatment in CSU patients are still unclear, and further studies are needed to evaluate the presence of baseline factors that can influence treatment outcome.

Abstract
In this study, for the first time, we demonstrated the presence of microRNAs and extracellular vesicles in human blastocoel fluid. The bioinformatic and comparative analyses identified the biological function of blastocoel fluid microRNAs and suggested a potential role inside the human blastocyst. We found 89 microRNAs, expressed at different levels, able to regulate critical signaling pathways controlling embryo development, such as pluripotency, cell reprogramming, epigenetic modifications, intercellular communication, cell adhesion and cell fate. Blastocoel fluid microRNAs reflect the miRNome of embryonic cells and their presence, associated with the discovery of extracellular vesicles, inside blastocoel fluid, strongly suggests their important role in mediating cell communication among blastocyst cells. Their characterization is important to better understand the earliest stages of embryogenesis and the complex circuits regulating pluripotency. Moreover, blastocoel fluid microRNA profiles could be influenced by blastocyst quality, therefore, microRNAs might be used to assess embryo potential in IVF cycles.

Abstract
miRNA expression profile and predicted pathways involved in selected limb-girdle muscular dystrophy (LGMD)2A/2B patients were investigated. A total of 187 miRNAs were dysregulated in all patients, with six miRNAs showing opposite regulation in LGMD2A versus LGMD2B patients. Silico analysis evidence: (1) a cluster of the dysregulated miRNAs resulted primarily involved in inflammation and calcium metabolism, and (2) two genes predicted as controlled by calcium-assigned miRNAs (Vitamin D Receptor gene and Guanine Nucleotide Binding protein beta polypeptide 1gene) showed an evident upregulation in LGMD2B patients, in accordance with miRNA levels. Our data support alterations in calcium pathway status in LGMD 2A/B, suggesting myofibre calcium imbalance as a potential therapeutic target. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
BACKGROUND & AIMS Nonalcoholic fatty liver disease (NAFLD) represents the most common chronic liver disease in industrialized countries. NAFLD has the potential to progress through the inflammatory phase of nonalcoholic steatohepatitis (NASH) to fibrosis, cirrhosis, and hepatocellular carcinoma. Identifying patients at risk for this transition is a relevant clinical challenge. The complexity of these phenotypes in vivo made necessary the development of in vitro models in order to dissect the molecular signalling affected in NAFLD and NASH, but also to identify potential circulating biomarkers. METHODS AND RESULTS We profiled the expression of 754 cellular and medium-secreted human miRNAs in HepG2 cells after lipotoxic (Palmitate, model of NASH) or not-lipotoxic stimuli (Oleate-Palmitate, model of NAFLD). Results were validated through Single TaqMan assays. We performed computational analysis of miRNA targets and pathways. Oleate-palmitate treatment induced a variation of 2.8% and 10% of total miRNAs in cells and medium, respectively; palmitate treatment caused 10% and 19% intracellular and extracellular miRNA deregulation, respectively. We validated miR-126, miR-150, miR-223, miR-483-3p, miR-1226*, and miR-1290 deregulation. Through computational analysis, we observed that targets of both intracellular and extracellular DE miRNAs were involved in processes associated with the onset and progression of NAFLD and NASH, such as fatty acid metabolism, apoptosis and inflammation. CONCLUSIONS These data would be useful to elucidate the role of miRNAs in the pathogenesis and progression of the NAFLD spectrum, but they also allow the identification of novel potential biomarkers for differential diagnosis to be tested in vivo.

Abstract
OBJECTIVE We aimed to deepen the clinical utility of humiliation assessment in the study of depression. METHOD We performed a correlational analysis of the relationship between humiliation, depression, resilience, and negative primary familial environment in 80 clinically depressed subjects (41 men and 39 women; mean age = 40.71, standard deviation SD = 9.94) and a strictly matched sample of 80 non-clinical subjects (41 men and 39 women; mean age = 40.64, SD = 10.24). We also implemented a hierarchical multiple regression analysis for each sample, to test the prediction of these variables on depression. RESULTS Humiliation showed positive correlations with depressive factors, while negative correlations emerged with resilience in both samples. The hierarchical multiple regression analysis showed humiliation to be the most predictive factor of depression in the clinical sample only. CONCLUSION This study improves the understanding of the relationship of humiliation and depression in both clinical and non-clinical populations.

Abstract
SCOPE The aim of this study is to gain a clear understanding of the level of knowledge and training of staff members from psychiatric rehabilitation services in the Province of Taranto (Italy), where patients released from judicial psychiatric hospitals will be admitted. MATERIALS AND METHODS A questionnaire taken from an earlier study on judicial psychiatric hospitals, conducted by The Ministry of Justice of the Department Penitentiary Administration - Superior Institute of Penitentiary Studies, was used in this study. Were contacted in advance of Directors 8 Community Rehabilitation and Psychiatric Care and Day Care Centres 7 present the province of Taranto, who has sought membership survey. RESULTS Many requests for information and training regarding the problems and challenges related to the management of individuals who are mentally ill, perpetrators of crimes, and persons who are held in protective custody are made by those who work in these institutions. CONCLUSIONS Hospital workers are highly apprehensive with regard to working with a patient population quite different from that which they are normally accustomed to. In order to confront these challenges, they, together with other colleagues from both the private and public services sector, have turned toward the concept of teamwork. One element of contradiction seems to be a low level of knowledge regarding what will be required of them when their work will be connected to the world of criminal justice in the future. The workers who were interviewed who have experience in working with patients from Judicial Psychiatric Hospitals seem to be up to the task of meeting the complex needs of the mentally ill and perpetrators of crimes within psychiatric rehabilitation facilities, as these patients must be kept under security.

Abstract
BACKGROUND Cricopharyngeal foreign bodies (FBs) impaction in adults is a common clinical problem; without treatment, the sequelae may be lethal due to local and/or mediastinal infection. When direct laryngoscopy and flexible fiberoptic endoscopy are ineffective, rigid endoscopy is the method of choice requiring general anesthesia. The new video laryngoscopes represent a great advancement in the assessment of the laryngeal inlet. Aim of the study was to assess the feasibility of identifying and removing FBs impacted at crycofaringeal and upper oesophageal sphincter by the video laryngoscope. METHODS In a period of 30 months, on an urgent basis, we systematically assessed by GlideScope® video laryngoscope all adult patients with a diagnosis of impacted crycofaringeal upper esophageal FB, after unsuccessful removal attempts in the otolaryngology or gastroenterology unit. RESULTS Twenty-six consecutive patients were evaluated. In conscious sedation by video laryngoscope 17 FBs were identified and removed from the hypopharynx or upper esophageal sphincter. In 9 patients rigid endoscopy in general anesthesia and tracheal intubation was necessary to remove FBs impacted beyond the upper esophageal sphincter. CONCLUSION In our experience video laryngoscope, because of the magnified vision, the better patient comfort and no requirement of general anesthesia, represents a great improvement in identifying and removing in conscious sedation even small and thin foreign bodies not recognized by radiological and otolaryngology examination and not readily detected by direct endoscopy.

Abstract
BACKGROUND Insulin-like growth factor 1 receptor (IGF1R) represents a novel molecular target in non-small-cell-lung cancer (NSCLC). IGF1R and epidermal growth factor receptor (EGFR) activation are essential to mediate tumor cell survival, proliferation, and invasion. This study investigates the prognostic role of IGF1R and EGFR in surgically resected NSCLC. MATERIALS AND METHODS IGF1R and EGFR copy number gain (CNG) were tested by fluorescence in situ hybridization (FISH) and protein expression by immunohistochemistry (IHC) in 125 stage I-II-IIIA NSCLC patients. RESULTS Fourty-six tumors (40.3%) were IGF1R FISH-positive (FISH+), and 76 (67.2%) were EGFR FISH+. Tumors with concomitant IGF1R/EGFR FISH+ were observed in 34 cases (30.1%). IGF1R and EGFR FISH+ were associated with SCC histology (p = 0.01 and p = 0.04, respectively). IGF1R and EGFR protein over-expression (IHC+) were detected in 45 (36.0%) and 69 (55.2%) cases, respectively. Tumors with concomitant IGF1R/EGFR IHC+ were detected in 31 (24.8%) patients. IGF1R/EGFR FISH+ and IGF1R/EGFR IHC+ were significantly associated (χ(2) = 4.02, p = 0.04). Patients with IGF1R/EGFR FISH+ and IGF1R/EGFR IHC+ were associated with shorter disease-free survival (DFS) (p = 0.05 and p = 0.05, respectively). Patients with concomitant IGF1R/EGFR FISH+/IHC+ had a worse DFS and overall survival (p = 0.005 and p = 0.01, respectively). The multivariate model confirmed that IGF1R/EGFR FISH+/IHC+ (hazard ratio (HR), 4.08; p = 0.01) and tumor stage (II-III vs I) (HR, 4.77; p = 0.003) were significantly associated with worse DFS. CONCLUSIONS IGF1R/EGFR FISH+ correlates with IGF1R/EGFR IHC+. IGF1R/EGFR FISH+/IHC+ is an independent negative prognostic factor for DFS in early NSCLC. These features may have important implications for future anti-IGF1R therapeutic approaches.

Abstract
Mammary carcinoma arising in ectopic breast tissue is an uncommon occurrence. Most reported cases have involved ductal carcinoma, but other types, such as medullary, papillary, and lobular carcinomas, have been described. For pathologists, the diagnosis of mammary carcinoma arising in ectopic breast tissue can be difficult, especially in the axilla, where carcinoma of adnexal origin must be excluded. We describe a 51-year-old woman who developed invasive secretory ductal carcinoma in ectopic left axillary breast tissue and micrometastatic carcinoma in an ipsilateral axillary lymph node. The carcinoma arose in a left axillary mass that had been present for several years, from which she had secreted fluid during prior menstrual periods.

Abstract
The ultrasound scissors are recently emerging as an alternative surgical tool for dissection and haemostasis and have been extensively used in the field of minimally invasive surgery. We studied the utility and advantages of this instrument compared with electrocautery to perform axillary dissection. The operative and morbidity details of thirty-five breast cancer patients who underwent axillary dissection using the ultrasound scissors were compared with 35 matched controls operated with electrocautery by the same surgical team. There was no significant difference in the operating time between the ultrasound scissors and electrocautery group (36 and 30 mins, p>0.05). The blood loss (60 +/- 35 ml and 294 +/- 155 ml, p<0.001) and drainage volume (200 +/- 130 ml and 450 +/- 230 ml, p<0.001) were significantly lower in the ultrasound scissors group. There was a significant reduction of draining days in ultrasound scissors group (mean one and four days, respectively p<0.05). There was significant difference in the seroma rate between the two groups (10% and 30%, respectively). Axillary dissection using harmonic scalpel is feasible and the learning curve is short. Ultrasound scissor significantly reduces the blood loss and duration of drainage as compared to electrocautery.

Abstract
AIM Iatrogenic damage to the recurrent laringeal nerve is the most feared complication in thyroid surgery and the main cause for vocal cord palsy. Prevention of such a lesion is based upon the thorough search for the nerve along its anatomic pathway. In the present study the Authors discuss an important anatomic variation: non-recurrent inferior laryngeal nerve, emphasizing the aspects of surgical anatomy, on the basis of their own experience in neck surgery. MATERIALS AND METHODS The study takes into conideration 301 surgical interventions on the thyroid gland, in 268 women and 33 men; consisting in 256 total thyroidectomies and 45 loboisthmectomies, as follows: 186 for nodular goiter, 48 for follicular nodule, 34 for papillifer carcinoma, 33 for toxic goiter. The identification and exposure of inferior laryngeal nerve was performed according to the principles and technique by Lahey. RESULTS The overall prevalence of non recurrent inferior laryngeal nerve was equal to 0.33% (1/301 operations). The anomaly is prevailing on the right side, being due by an anomalous reabsorption of the IV ventral arch. This is the cause of the formation of a subclavian artery that is responsible for dysphagia lusoria. CONCLUSIONS The rationale for the preservation of recurrent nerve is its systematic identification and exposure along all its course from its laryngeal entry. Diagnosis of non recurrent inferior laryngeal nerve is exclusively intra-operative. The anomaly is clinically asymptomatic and its suspicion can be posed in case of vascular anomalies or dysphagia. In such a circumstance the golden diagnostic tool is the angio Tc-RMN, while both the EGDS and baritate esophagous can be of some diagnostic help.

Abstract
BACKGROUND Medullary Thyroid Carcinoma (MTC) originates from the thyroid C cells and accounts for approximately 5-9% of all thyroid cancers. Aim of this study was to retrospectively evaluate the outcomes of 41 patients with MTC who underwent treatment at our institution. PATIENTS AND METHODS. We reviewed the records of 41 patients who underwent surgery between 1995 and 2004. The patients were divided into two groups: A) patients (n 30) without any previous surgery. B) patients (n 11) previously thyroidectomized and high calcitonin levels with or without radiological evidence of local regional or distant metastases. We performed total thyroidectomy with central compartment lymphadenectomy and ipsilateral modified radical neck dissection in group A patients. Group B patients underwent re-excision of the central neck compartment and bilateral modified radical neck dissection if it had not been previously performed. RESULTS Most patients had major reduction in postoperative calcitonin levels. Compartmental dissection of the cervical node significantly improved the results of primary surgery and calcitonin returned to normal levels in approximately 60% of the patients in group A, but only the 30% of the patients in group B. CONCLUSIONS The extent of the primary surgical resection and the evidence of local or distant metastases significantly influence the outcome of MTC patients. An extensive lymphadenectomy performed early in the treatment and re-operative cervical lymphadenectomy in patients with persistently high calcitonin levels after thyroidectomy significantly improved the outcome, although re-operation rarely results in normalized calcitonin levels and is associated with a higher incidence of complications.

Abstract
Molecular characterization of human female gametes should make it easier to understand the basis of certain infertility disorders. Biologically significant mRNAs have been analysed in single oocytes to search for molecular biomarkers of oocyte quality. Initial analysis was focused on mRNA for proteins involved in cell growth and cycle control, specifically those encoding members of the general transcription apparatus such as the subunits of the general transcription factor TFIID. This heteromultimeric protein, comprising about 15 subunits, is the most important general transcription factor of the second class. These proteins are essential for the initiation of transcription of protein-coding genes, so they must be present in mature oocytes for mRNA synthesis during the first phases of embryonic development. Semi-quantitative reverse transcriptionpolymerase chain reaction was used to identify different TFIID subunits in single oocytes and to search for differences in expression as compared with control tissues. The data show that the mRNAs for most TFIID subunits are indeed synthesized in oocytes, but their expression profiles differ markedly. TATAbox-binding protein associated factor 4B (TAF4B), TAF5 and TATAbox-binding protein-like 2 (TBPL2) are expressed at higher levels in oocytes than in control tissues. It is suggested that they could be used as biomarkers of oocyte quality.

Abstract
AIM Differentiated thyroid carcinomas (DTC) have a favourable outlook overall. Cornerstone of treatment is total thyroidectomy (TT), followed, if needed, by radiometabolic therapy. Such lesions however show a definite tendency to recur (about 35% of cases), generally in the first decade of follow-up: in 70% of patients such recurrence is local. Surgical resection is the only curative treatment option for local recurrence of well-differentiated thyroid cancer. Intraoperative ultrasonography (US) can be of significant help in facilitating localization and complete resection of lesions. The aim of the study was to review the authors' own experience with the use of such diagnostic method in the clinical setting of thyroid neoplasm recurrence. METHODS Between January 2005 and March 2008 31 patients with DTC recurrences underwent intraoperative US exploration. Recurrences were easily identified and resected in all patients. Postoperative tireoglobuline (TG) was undetectable. RESULTS In all 31 patients preoperative US confirmed the presence of the lesion. In 26 patients digital exploration of the surgical field did not yield a definitively positive finding, whereas in 5 the lesion was easily palpable. Intraoperative US revealed the presence of pathologic tissue in all cases, with examination time ranging from 4 to 14 minutes (median 8 minutes). In all cases surgical resection was complete, with pathologic confirmation of the sample, and no necessity to extend ablation. CONCLUSION Intraoperative US can be of significant help in the identification of DTC recurrences, in particular when lesion dimensions are smaller than 10 mm in diameter and can facilitate a more radical excision of the tumor in a surgical field were anatomical landmarks can be altered by previous surgery and/or radiometabolic therapy.

Abstract
As the prevalence of breast cancer has increased over recent years many cases with unusual presentation are emerging. This review attempts to identify different types of primary malignancies that can affect the breast. A five years review was undertaken at the Breast Unit of Azienda Ospedaliera "Santa Maria", Terni (Italy). All cases of breast malignancy admitted to the Breast Unit between 2001 and 2005 were reviewed: 750 patients were diagnosed with malignant breast disease. Primary breast lymphoma (was found only in two cases accounting for an incidence of 0,26%. The pre-operative diagnosis was infiltrating carcinoma in both cases and the patients were treated with surgery and systemic chemotherapy; currently they are disease- free.

Abstract
INTRODUCTION We carried out a retrospective analysis of our experience in the management of Differentiated Thyroid Carcinoma (DTC), in order to better define prognostic factors (age, gender, histological type, stage) and outline a standard procedure, where it's possible, for surgical treatment. PATIENTS AND METHODS Patient population consisted of 432 cases, operated from 1978 to 2003. We carried out 285 operations of total thyroidectomy of which 39 associated to some kind of lymphadenectomy, 66 totalization (21 pts had been operated in other institutes), 60 subtotal thyroidectomies and 21 lobo-isthmectomies. Survival and mortality curves for age, sex, histological type, grading and staging have been calculated. Kaplan-Meyer statistical elaboration for disease-free interval and Mann-Whitney test for the comparison of different clinical and pathological data have been employed. RESULTS The statistical analysis puts in evidence that on 432 cases examined, with a follow-up from 1 to 25 ys (median = 6.33 ys) and with a drop-out of 60 cases (13.8 %), total mortality for cancer has been of 24 cases (6,4%), with a median interval free by disease of 4.2 ys (range 5 months to 25 ys), and a probability to stay free by disease at 12 and 24 months respectively of 95.1% and 91.6%. The median survival is resulted of 5.8 ys (range 1 to 25 ys) with a probability of survival at 24 and 48 months respectively of 97.5% and 94.3%. The multivariate analysis evidences the most important variables, i.e. age > 45 ys, tumor of intermediate malignancy, with size 1.5 cm, operative M+, significantly condition the prognosis, noticeably getting worse it, independently by the kind of carried out operation. CONCLUSION Our present therapeutic choices are: 1. total thyroidectomy in the treatment of the apparently benign pathology when bilaterally with spread; the checking at the final histological exam of a cancer makes however think adequate the carried out operation; 2. lobo-isthmectomy in the treatment of unilateral benign pathology or with suspect FNAB for follicular neoplasm; the histological checking of a cancer makes think the operation adequate only in presence of favourable prognostic parameters, but in presence even of just one unfavourable variable, we consider necessary the totalization; 3. total thyroidectomy in presence of a certain or strongly suspected preoperative diagnosis of cancer.

Abstract
Due to their ballistic precision, apoptosis induction by protons could be a strategy to specifically eliminate neoplastic cells. To characterize the cellular and molecular effects of these hadrons, we performed dose-response and time-course experiments by exposing different cell lines (PC3, Ca301D, MCF7) to increasing doses of protons and examining them with FACS, RT-PCR, and electron spin resonance (ESR). Irradiation with a dose of 10 Gy of a 26,7 Mev proton beam altered cell structures such as membranes, caused DNA double strand breaks, and significantly increased intracellular levels of hydroxyl ions, are active oxygen species (ROS). This modified the transcriptome of irradiated cells, activated the mitochondrial (intrinsic) pathway of apoptosis, and resulted in cycle arrest at the G2/M boundary. The number of necrotic cells within the irradiated cell population did not significantly increase with respect to the controls. The effects of irradiation with 20 Gy were qualitatively as well as quantitatively similar, but exposure to 40 Gy caused massive necrosis. Similar experiments with photons demonstrated that they induce apoptosis in a significantly lower number of cells and in a temporally delayed manner. These data advance our knowledge on the cellular and molecular effects of proton irradiation and could be useful for improving current hadrontherapy protocols.

Abstract
The present study reports the results of surgical treatment of 175 consecutive chronic pilonidalis sinus cases by excision alone, excision and primary closure, excision and Dufourmentel's flap technique. The analysis of hospital stay , average recovery time, patient compliance and percentages of failures and recurrences enables us to state that Dufourmentel's technique is the best choice, allowing fast recovery with minimal discomfort and lower rate of recurrence. Moreover the good compliance of the technique and the use of recently introduced more effective local anaesthetics have allowed us to plan the treatment in a day-surgery setting with good clinical results.

Abstract
Extrauterine or external endometriosis (e.e.) describes ectopic localization of functional endometrial tissue, a finding whose incidence is increasing due to the diffusion of laparoscopic procedures. The clinical presentation of such disease is often non-specific, even in those cases with a definite surgical indication, depending on the site and pathology of the lesions. Surgical planning is therefore difficult at times, specifically regarding the extent of resection in patients--as young women--willing to maintain fertility. The Authors report on 7 cases observed in their own experience (inguinal endometriosis--1 case, umbilical endometriosis--1 case, abdominal wall endometriosis--3 cases, intestinal endometriosis--1 case, diaphragmatic endometriosis associated with pneumothorax--1 case), representing the wide range of clinical settings related to e.e. Based on literature data, an analysis of clinical and diagnostic issues is carried out. Specifically, the problems related to extent of surgical resection in multifocal cases, possible malignant degeneration and localization on abdominal wall scars are discussed.

Abstract
In this paper we present a new Multiple Sequence Alignment (MSA) algorithm called AntiClusAl. The method makes use of the commonly use idea of aligning homologous sequences belonging to classes generated by some clustering algorithm, and then continue the alignment process ina bottom-up way along a suitable tree structure. The final result is then read at the root of the tree. Multiple sequence alignment in each cluster makes use of the progressive alignment with the 1-median (center) of the cluster. The 1-median of set S of sequences is the element of S which minimizes the average distance from any other sequence in S. Its exact computation requires quadratic time. The basic idea of our proposed algorithm is to make use of a simple and natural algorithmic technique based on randomized tournaments which has been successfully applied to large size search problems in general metric spaces. In particular a clustering algorithm called Antipole tree and an approximate linear 1-median computation are used. Our algorithm compared with Clustal W, a widely used tool to MSA, shows a better running time results with fully comparable alignment quality. A successful biological application showing high aminoacid conservation during evolution of Xenopus laevis SOD2 is also cited.

Abstract
OBJECTIVE Tracheal stenting for cicatricial stenoses is reserved for patients whose lesions are deemed inoperable for local or general reasons. The aim of our study was to verify the long-term results of silicone tracheal stents in such a clinical setting. METHODS Clinical data of 45 patients treated by tracheal silicone stents, between 1987 and 1999, were reviewed. All patients had highly symptomatic cicatricial stenoses; they were selected for stenting rather than for surgery because of local and general conditions. This series has been divided in two groups according to the purpose of stenting: bridge to surgery or definitive treatment. Follow-up ranged between 12 and 83 months. Twenty-seven patients received a Montgomery T tube (Hood Laboratories, Pembroke, Mass), 16 a Dumon stent (Novatech, Plan de Gras, France), and 2 a Dynamic stent (Rusch, Kernen, Germany). RESULTS No procedure-related mortality was observed. Nine patients underwent curative resection and reconstruction after a variable stenting period; one had a recurrent stenosis and was treated for palliation with a T tube. Tracheal stenting was performed for palliation as a definitive treatment in 37 patients. Among this group, 11 patients died of unrelated causes at a median of 10 months after the endoscopic treatment. The stent was permanently removed in 10 after a median interval of 32 months (range 9-70 months); in 4 others, symptomatic recurrence of the stenosis was observed within 6 weeks of stent removal. None of the patients successfully decannulated had a completely normal tracheal lumen but all remained asymptomatic because the residual stenosis was mild or well tolerated for concomitant limitation of physical activity. CONCLUSIONS Long-term treatment with a silicone stent was safe and well tolerated in cicatricial tracheal stenoses. This procedure can be considered as a bridge to curative surgery or as a definitive treatment. The latter, generally performed for palliation, may provide satisfactory therapeutic results in selected patients, even in the presence of severe circumferential stenoses.

Abstract
The incidence of thyroid cancer, which accounts for 1-2% of all malignancies, constantly increasing. Its management requires an integrated approach, in which the surgeon plays a pivotal role, providing the basis for further treatment. At present, the extent of exeresis, the lymph-node dissection technique and the management of upper respiratory-digestive tract infiltration are still debatable issues. The authors report on their experience with 243 surgically treated thyroid malignancies over the period from January 1986 to December 1999. The operations performed were: total thyroidectomy 226 cases, lobo-isthmectomy 3 cases, total thyroidectomy + lung metastasectomy 1 case, total thyroidectomy + SE quadrantectomy 1 case, total thyroidectomy + monolateral modified neck dissection 30 cases, total thyroidectomy + bilateral modified neck dissection 17 cases, total thyroidectomy + radical neck dissection 1 case, total thyroidectomy + tracheal sleeve resection 5 cases. In 9 cases, extensive tracheal involvement (5.5 cm), age or neoplastic histology allowed only palliative treatment (endoscopic recanalization + tracheal endoprosthesis or tracheostomy. Nd-Yag laser endoscopic recanalization was performed in 2 patients as a preliminary stage in subsegmental radical treatment, and in 5 cases for palliation. Recurrent laryngeal nerve palsy occurred in 3 cases, long-term hoarseness in 2, and hypoparathyroidism in 4. The overall mean hospital stay was 4.8 days. Of 299 patients still alive, 215 are free of disease. Surgery is the treatment of choice, with the goal of completely removing the neoplasm, together with any anatomical structures involved in infiltration (muscles, respiratory-digestive tract, lymph nodes). Satisfactory palliation can be achieved by endoprosthesis deployment or tracheostomy in all cases where surgery is ruled out due to extent of disease, patient age or histological type.

Abstract
BACKGROUND A safe and dependable venous access is mandatory in order to perform cancer chemotherapy and monitor blood values in the neoplastic patient. Prolonged infusions of medications with sclerosing action may damage the vessel wall, inducing chemical thrombophlebitis. Furthermore, extravasation of necrotizing compounds may be a danger to the patient. The application of totally implantable venous access systems (VAS) started in 1982, in the United States of America, where at present 500,000 devices are implanted annually. In Italy such method has been introduced in a later period, with a constantly growing trend. VAS devices have evolved since their first presentation, and so have application techniques: the original surgical route has been supported by the percutaneous one, considered most appropriate by several Centers. In this study, personal experience concerning application of VAS in cancer patients is presented. METHODS From July 1994 to February 1998, at the General Thoracic Surgery Dept. of the University of Perugia, 198 VAS have been implanted in 195 patients. During the first period all the systems have been applied by surgical cutdown of the cephalic vein (150 cases). In the last 12 month the percutaneous technique for vein puncture has been adopted in 48 patients. RESULTS Immediate and late complications have occurred: among the former, pneumothorax, hematoma, malposition; among the latter, infection, subclavian vein thrombosis, catheter rupture. The results are analysed after an extensive review of the international literature; pros and cons of the different implantation techniques and the technical aspects useful for preventing complications are underlined.

Abstract
In Paracentrotus lividus sea urchin embryos, at blastula stage, there is an abrupt increase in the abundance of alpha and beta tubulin transcripts in particular of the PI beta 1, PI beta 2 and PI alpha 2 forms. In order to assign specific functions to the various embryonic tubulin genes, we have used whole-mount in situ hybridization to determine spatial patterns of expression of five different alpha and beta tubulin embryonic genes. The PI beta 3 transcripts, as previously shown for PI alpha 2, start to localize in a few founder cells from which the neurogenic territory differentiates. The other four embryonic tubulin mRNAs (PI beta 1/2 and PI alpha 1/10), are localized in the ciliated band- and gut-territory. These territories originate by morphogenetic processes, which occur in late embryogenesis in the sea urchin and depend on cellular interactions. In particular, the interactions between the oral and aboral ectoderm specify the position of the ciliated band, whereas the invagination of the vegetal plate forms the gut territory. We suppose that the increase in alpha and beta tubulin transcripts could be functionally related to these two morphogenetic events. Our results show in fact that specific tubulin isotypes, or a mix of them, are expressed in and mark the ciliated band and the neighboring oral/aboral ectoderm cells of the ciliated band, in addition to the cells of the gut territory. The same localization of all these tubulin transcripts has been confirmed by whole-mount in situ hybridization experiments performed on embryos treated with agents able to induce deciliation or exogastrulation. Furthermore a putative correlation of PI beta 2 with cilium formation has been shown by the results obtained on deciliated embryos.

Abstract
We have used Northern blot and whole-mount in situ hybridizations to analyze the temporal and spatial expression pattern of the Pl alpha 2 alpha-tubulin gene in Paracentrotus lividus sea urchin embryos. The Pl alpha 2 transcript is first detectable at 14 h post-fertilization (blastula stage) and it is only expressed in the oral ectoderm. The amount of transcripts of this gene increases throughout development and accumulates up to the pluteus stage. In this stage the Pl alpha 2 transcript is localized in the neural structures of the embryo. We conclude that the Pl alpha 2 gene is an early neurogenic territory marker. Furthermore we have observed the same localization of the Pl alpha 2 transcript in the Zn(++)- or phenytoin-treated embryos, confirming the animal localization of the Pl alpha 2 transcript and its specific relation to neurogenic territory, whose differentiation starts from few founder cells present at blastula stage.

Abstract
Experimental results and preliminary clinical experience with synthetic reabsorbable materials in chest wall reconstruction are reported. Six beagle dogs underwent chest wall resection involving three or four consecutive ribs. Reparative procedure was performed by construction of a polydioxanone-band grid, anchored to the adjacent undamaged ribs. A mild wound infection developed in 1 animal but resolved without rejection of the prosthesis. The experimental material has shown favorable properties, both mechanical and biological. Subsequently, 11 patients, with different indications, underwent reconstructive procedures of the chest wall with reabsorbable prostheses. No complications have occurred. Long-term stability was excellent in all patients, with a mean follow-up longer than 6 months. The advantages of reabsorbable compounds are pointed out along with the possible applications for chest wall reconstruction after chest wall resection.

Abstract
In recent years surgery for hepatic and pulmonary metastases has been undertaken with a curative intent in a growing percentage of cases. In the present study the Authors evaluate their own experience in such a field, and summarize the state of the art, as it appears from a review of the international literature. At present, the subject is not settled, as several aspects are matter of debate (prognostic significance of free interval, tumor doubling time, number and location of metastatic lesions, histologic type, and stage, of the primary tumor, approach to synchronous metastases, accuracy of preoperative diagnosis), with different therapeutic implications according to the hepatic or pulmonary site. Pulmonary metastases should be managed by resection through a median sternotomy, in order to allow thorough exploration of both lungs. Hepatic lesions (from colorectal primaries) should be resected with a free margin not less than 1-2 cm. The need for uniformity of selection criteria and for the establishment of protocols including adjuvant therapy is strongly felt.

Abstract
Prolamine is an alcoholic solution of zein, with the property of polymerizing within 15 minutes in a humid medium. Such a substance has been injected in the pancreatic duct of 10 pigs with a microsurgical technique, causing complete occlusion. The prolamine gel produces a progressive fibrosclerosis of the exocrine pancreatic parenchyma, sparing the endocrine portion. The resulting pancreatic atrophy avoids the occurrence of inflammatory complications that often hamper surgery on such gland. The 10 pigs under study showed post-operative normal values of blood glucose and insulin, and a decrease in serum alpha-amylase levels. Complications occurred in only one case, and the microscopic pattern was similar in all cases. Microsurgical approach and use of prolamine are considered effective both in pancreatic transplantation and in chronic pancreatitis.
