Abstract
PURPOSE To report the clinical implications of an initial experience with transoral endoscopic thyroidectomy vestibular approach (TOETVA). METHODS From March to November 2017, five cases of TOETVA were performed. Data reported include patient demographics, indication for surgery, extent of surgery, operative time, the need to convert to cervicotomy, the length of hospital stay and post-operative pain and morbidity. Unconventional complications regarded as specific for TOETVA were reported. The burden of surgery on the patient's quality of life was evaluated using the 36-item short form (SF-36) health survey 1 month after surgery. RESULTS All patients were females with a mean age of 36 years. They all underwent a right-sided hemithyroidectomy for a solitary thyroid nodule measuring on average 3.5 cm in size. The nodule was reported as Bethesda category II (n = 3), III (n = 1), and IV (n = 1) on fine needle aspiration cytology. The mean operative time was 122 min. Conversion to a transverse cervicotomy was required in one case. None of the patients developed post-operative bleeding, and none experienced vocal fold or mental nerve palsy. Surgical site infection did not occur. All patients developed subcutaneous emphysema that resolved within 12-48 h. All patients reported a long-standing bothersome pulling sensation along the surgical track that resulted in a poor outcome in some scales of the SF-36 survey. Flap perforation occurred in one case. The median VAS score was 3. CONCLUSION Patients strongly motivated to undergo a novel surgical procedure tailored to their needs and desires should be properly counselled particularly regarding unconventional procedure-related complications.

Abstract
BACKGROUND Thyroid nodules are a common clinical problem, and differentiated thyroid cancer is becoming increasingly prevalent. METHODS Six scientific Italian societies entitled to cure thyroid cancer patients (the Italian Thyroid Association, the Medical Endocrinology Association, the Italian Society of Endocrinology, the Italian Association of Nuclear Medicine and Molecular Imaging, the Italian Society of Unified Endocrine Surgery and the Italian Society of Anatomic Pathology and Diagnostic Cytology) felt the need to develop a consensus report based on significant scientific advances occurred in the field. OBJECTIVE The document includes recommendations regarding initial evaluation of thyroid nodules, clinical and ultrasound criteria for fine-needle aspiration biopsy, initial management of thyroid cancer including staging and risk assessment, surgical management, radioiodine remnant ablation, and levothyroxine therapy, short-term and long-term follow-up strategies, and management of recurrent and metastatic disease. The objective of this consensus is to inform clinicians, patients, researchers, and health policy makers about the best strategies (and their limitations) relating to the diagnosis and treatment of differentiated thyroid cancer.

Abstract
Recent in situ hybridization experiments have shown a high content of IGF-II mRNA in breast cancer stroma. The aim of this study was to examine the relationship between IGF-II protein expression and several prognostic parameters in 75 infiltrating ductal carcinomas (IDC) of the breast. Tissue sections were evaluated for proliferative activity, IGF-II protein, ER, PgR, p53, and p21 expression using immunohistochemical procedures. The degree of stromal proliferation was assessed. Menopausal status, axillary lymph node involvement and nuclear grade were known. Thirty-five patients (44.3%) were premenopausal and 47 (62.6%) had lymph node metastases. Marked stromal proliferation was found in 34 (45.3%) specimens and high nuclear grade in 20 (26.5%). Eighteen tumors (24%) showed no IGF-II immunostaining. In the positive cases, IGF-II was detected both in the tumor stroma and in the cytoplasm of epithelial cancer cells: a high IGF-II content was found in 12 specimens (16.0%), a low content in 14 (18.7%) and a moderate content in 31 (41.3%). Twenty-four tumors (32.0%) showed high proliferative activity. Both ER and PgR were expressed in the nucleus of cancer cells: 49 tumors (65.3%) were ER positive (ER+) and 34 (45.3%) PgR positive (PgR+). p21 protein was detected in 37 tumors (49.6%) and p53 in 12 (16%). IGF-II protein was not correlated with menopausal status, lymph node metastases, nuclear grade, proliferative activity, ER or p53. In contrast, IGF-II correlated strongly with stromal proliferation (p=0.008), PgR (p=0.03) and p21 (p=0.01). This study demonstrates that in IDC of the breast IGF-II protein is expressed in the epithelium and stroma of the majority of tumors and is correlated with stromal amount, PgR and p21 expression. These preliminary results indicate that IGF-II expression in breast cancer is connected with two important regulators of breast cancer growth and differentiation.

Abstract
VEGF is a specific mitogen and survival factor for endothelial cells and a key promoter of angiogenesis in physiological and pathological conditions. Nevertheless, VEGF tissue evaluation in cancer patients as a prognostic factor compared to the conventional histological and biological parameters is still controversial. In this case-control study, tissue VEGF was retrospectively determined by immunohistochemistry and related to T, N, ER, PgR, c-erbB-2, p53, MIB-1 and cyclin D1 in 129 breast cancer patients. Seventy-four of these patients had developed distant metastases postoperatively. The remaining 55 patients had remained disease-free >10 years after surgery. In 17 (13%) of the 129 patients (six with distant metastases and eleven disease-free) tissue and plasma VEGF were concomitantly evaluated. In univariate analysis no significant differences in VEGF and tumor size were found between metastatic and disease-free patients, whereas there were significant differences in N, ER, PgR, c-erbB-2, p53, MIB-1 and cyclin D1 (p ranging from 0.001 to 0.0001). In multivariate analysis VEGF showed less significance than N, ER, c-erbB-2, MIB-1 and cyclin D1 (p=0.012, p=0.007, p=0.005, p=0.005, p=0.002 and p=0.001, respectively). VEGF was a significant unfavorable prognostic indicator only in the N+ subset (p=0.015), while ER (p=0.05 and p=0.021) and MIB-1 (p=0.031 and p=0.022) were significant in both the N+ and N– subgroups. In multivariate analysis in the 74 metastatic cases VEGF did not show any significance in relation to disease-free interval and overall survival from the time of mastectomy and from the time of relapse, whereas N and PgR did (p ranging from 0.018 to 0.001). In conclusion, tissue VEGF does not seem a suitable candidate to replace conventional histological and other common biological prognostic factors in breast cancer.

Abstract
PURPOSE Minimally invasive video-assisted parathyroidectomy (MIVAP) is one of the most widespread targeted parathyroid surgeries for primary hyperparathyroidism (PHP). The aim of this study was to assess its limits and propose an expansion of its indications in the management of parathyroid pathology. METHODS A retrospective analysis of 77 consecutive patients who underwent MIVAP for PHP between Jan and Oct 2016 was conducted. The adequacy of the procedure and/or the need to convert to a standard cervicotomy was the main outcome of interest. Secondary outcomes of interest included: operative time, postoperative morbidity, postoperative pain assessed by the visual analogue scale (VAS) score, and the length of the surgical incision. RESULTS There were 64 females and 13 males with a mean age of 51 years. In one patient a concomitant en bloc thyroid lobectomy was required due to features suspicious of parathyroid carcinoma while exploration was required in two other patients. None of these three cases required conversion to standard cervicotomy. The mean operative time, length of incision and VAS score was 31 min, 17 mm and 1.6, respectively. Biochemical cure was achieved in all patients, and no postoperative morbidities were reported. CONCLUSION MIVAP offers the ability to perform a neck exploration and/or an en bloc thyroid lobectomy without the need to convert to a standard cervicotomy. Therefore, it not only serves as a targeted parathyroid procedure but also a potential alternative to full neck exploration.

Abstract
PURPOSE The extent of surgery for pediatric papillary thyroid carcinoma is debatable. The aim of this study was to evaluate the feasibility of offering pediatric patients a tailored surgical approach based on certain clinical features. METHODS A national multicenter retrospective review of 250 pediatric patients treated for papillary thyroid carcinoma in a 14-year period was performed. Outcomes of interest included tumor-related features, type of surgery, surgical morbidity, disease-free and overall survival rates. Recurrence was thoroughly analyzed with particular focus on how it correlated with certain patient- and tumor-related features. RESULTS The majority of patients (58.8 %) had tumors >2 cm in size. Nodal involvement occurred in 115/250 (46 %) patients and distant metastasis in 4 % (10/250). Total thyroidectomy and lobectomy were performed in 90.4 % (226/250) and 9.6 % (24/250) of patients, respectively. The overall rate of surgical complications was 20.8 % (52/250). These included transient and permanent hypoparathyroidism (13.6 and 4.4 %, respectively), and vocal fold palsy (2.8 %). All surgical complications occurred exclusively in the total thyroidectomy group. The rate of recurrent disease was 12 % (30/250) with the vast majority of recurrences (96.6 %) occurring in the total thyroidectomy group. The risk of recurrence correlated significantly with certain tumor-related features (size > 2 cm, multifocality, extrathyroidal invasion, nodal positivity, and distant metastasis). However, it did not correlate with the patient's age or sex. Overall survival was 100 %. CONCLUSION Pediatric patients are likely to benefit from a tailored surgical strategy. Uniformly offering patients total thyroidectomy seems to be an overly radical approach.

Abstract
PURPOSE The diagnostic, therapeutic and health-care management protocol (Protocollo Gestionale Diagnostico-Terapeutico-Assistenziale, PDTA) by the Association of the Italian Endocrine Surgery Units (U.E.C. CLUB) aims to help treat the patient in a topical, rational way that can be shared by health-care professionals. METHODS This fourth consensus conference involved: a selected group of experts in the preliminary phase; all members, via e-mail, in the elaboration phase; all the participants of the XI National Congress of the U.E.C. CLUB held in Naples in the final phase. The following were examined: diagnostic pathway and clinical evaluation; mode of admission and waiting time; therapeutic pathway (patient preparation for surgery, surgical treatment, postoperative management, management of major complications); hospital discharge and patient information; outpatient care and follow-up. RESULTS A clear and concise style was adopted to illustrate the reasons and scientific rationales behind behaviors and to provide health-care professionals with a guide as complete as possible on who, when, how and why to act. The protocol is meant to help the surgeon to treat the patient in a topical, rational way that can be shared by health-care professionals, but without influencing in any way the physician-patient relationship, which is based on trust and clinical judgment in each individual case. CONCLUSIONS The PDTA in thyroid surgery approved by the fourth consensus conference (June 2015) is the official PDTA of U.E.C. CLUB.

Abstract
BACKGROUND The objective of the study was to investigate the relationship between molecular genetic features and the standard criteria of risk assessment in patients affected by gastrointestinal stromal tumours (GISTs). METHOD A review was conducted of a series of 30 patients, with a mean age of 67 years, who underwent surgery for primary GISTs. R0 resection was accomplished in 27 patients. CD117, CD34 desmin, vimentin, S-100 and smooth muscle actin were immunohistochemically tested to achieve a diagnosis of GIST. The loss of wild-type KIT or platelet-derived growth factor receptor alpha (PDGFRα) genes was investigated by sequencing the tumour DNA. RESULTS Tumour genes mutations were reported in 23 patients (77%), and wild-type in seven. Mutations on the KIT gene occurred in 18 patients, and mutations on the PDGFRα gene in five. The average sizes of the GIST were 8.7 cm, 5.4 cm and 5.9 cm for KIT gene-mutated, PDGFRα gene-mutated and wild-type tumours, respectively. KIT gene mutations were detected in 50% of gastric and in 70% of extragastric GISTs. Moreover, 70% of tumours with a mitotic rate ≥ 5 x 50 highpower fi elds (HPFs) underwent KIT gene mutations. Conversely, PDGFRα mutations were observed only in gastric GISTs with a mitotic rate ≤ 5 x 50 HPFs. By stratifying GISTs according to classes of risk, KIT mutation was shown in most of the high-risk tumours. PDGFRα mutations occurred exclusively in lower classes of risk. CONCLUSION Molecular analysis data might have a role as a prognostic variable in models of risk assessment for patients with GISTs.

Abstract
BACKGROUND The minimally invasive video-assisted approach was developed for primary hyperparathyroidism in 1997 and the year after for thyroid disease. Since then, the technique has been adopted worldwide, and indications moved from the initial benign disease to low-risk and intermediate-risk carcinoma, demonstrating a level of oncologic radicality comparable to the conventional open approach when inclusion criteria are strictly respected. METHODS Between 1998 and 2014, 2412 minimally invasive video-assisted thyroidectomies (MIVAT) were performed in our department. The indication for surgery in 825 patients (34.3 %) was a malignant tumor, in particular, a papillary carcinoma in 800 patients. Among them, 528 patients operated on between 2000 and 2009 had a mean complete follow-up of 7.5 (standard deviation, 2.3) years. RESULTS A total thyroidectomy was performed in 1788 patients (74.1 %) and a hemithyroidectomy in 564 (23.4 %). Also performed was central compartment lymphadenectomy in 31 patients (1.3 %) and parathyroidectomy for the presence of a solitary parathyroid adenoma in 29 (1.2 %). Mean duration of the procedure was 41 (standard deviation, 14) minutes. After a mean follow-up of 7. 5 years, 528 patients who underwent MIVAT for low-risk or intermediate-risk papillary carcinoma presented a cure rate of 85 % (undetectable thyroglobulin), comparable with the 80 % rate reported in patients who had undergone open thyroidectomy during the same period. CONCLUSIONS After a long experience and a considerable number of procedures performed in a single center, MIVAT is confirmed as a safe operation, with a complication rate comparable with open thyroidectomy. MIVAT offers a cure rate for the treatment of low-risk and intermediate-risk malignancies that is comparable with an open procedure when inclusion criteria are strictly respected.

Abstract
BACKGROUND The benefits of prophylactic central compartment lymph node dissection (pCCND) in papillary thyroid cancer (PTC) are still under investigation. This treatment seems to reduce PTC recurrence/mortality rates but has a higher risk of surgical complications. The lack of prospective randomized trials does not allow definitive recommendations. The aim of this prospective randomized controlled study was to evaluate the clinical advantages and disadvantages of pCCND. PATIENTS A total of 181 patients with PTC without evidence of preoperative/intraoperative lymph node metastases (cN0) were randomly assigned to either Group A (n = 88) and treated with total thyroidectomy (TTx) or Group B (n = 93) and treated with TTx + pCCND. RESULTS After 5 years of followup, no difference was observed in the outcome of the two groups. However, a higher percentage of Group A were treated with a higher number of (131)I courses (P = .002), whereas a higher prevalence of permanent hypoparathyroidism was observed in Group B (P = .02). No preoperative predictors of central compartment lymph node metastases (N1a) were identified. Only three patients were upstaged, and the therapeutic strategy changed in only one case. CONCLUSIONS cN0 patients with PTC treated either with TTx or TTx + pCCND showed a similar outcome. One advantage of TTx + pCCND was a reduced necessity to repeat (131)I treatments, but the disadvantage was a higher prevalence of permanent hypoparathyroidism. Almost 50% of patients with PTC had micrometastatic lymph nodes in the central compartment, but none of the presurgical features analyzed, including BRAF mutation, was able to predict their presence; moreover, to be aware of their presence does not seem to have any effect on the outcome.

Abstract
BACKGROUND The distinction between follicular adenomas (FAs) and well differentiated follicular and papillary carcinomas is often a demanding task and sometimes only intuitive. AIM We report an histomorphological evaluation of follicular neoplasms [FAs, follicular carcinomas (FCs), and follicular variant of papillary carcinomas (FVPTCs)], supported by a qualitative and quantitative image analysis and by a molecular characterization. MATERIAL AND METHODS Tumor fibrosis and haemorrhage, neoplastic capsule thickness, follicle diameter, number of neoplastic cells, nuclear diameter of neoplastic cells, vessels density, vessels area and intratumoral distribution were evaluated. Ras and BRAF mutations, RET/PTC1, RET/PTC3, and PAX8/PPARγ rearrangements were analyzed. Correlations with clinico-pathological features have been studied. RESULTS We found that FAs had a more extensive intratumoral haemorrhage, while malignant neoplasms were characterized by an evident fibrosis, higher cellularity and larger size. FVPTCs had higher nuclear diameter; cells count was higher in the minimally invasive follicular thyroid carcinomas, as well as a thickener neoplastic capsule. The CD34 stain showed a higher microvessel density in the FVPTCs group. A higher peripheral vessels distribution was observed only in malignant neoplasms. We observed overall Ras mutations in 2.4% of adenomas, in 41.5% of FVPTCs, and in 44.8% of FCs. It is outstanding that there is a marked difference in the Ras mutation distribution between the benign and malignant tumors in our series. CONCLUSIONS We found that genotyping of Ras gene family together with an accurate analysis of selected morphological features could help in the differential diagnosis of follicular-derived thyroid neoplasms.

Abstract
Adjuvant therapy in colorectal cancer has evolved to become the standard of care, whereas the tumor capability of activating effective mechanisms of defence against both chemical and physical cytotoxic agents represents a serious obstacle to the successful therapy of human tumors. Therefore, the possibility to have an assay useful to measure the drug sensitivity of tumor cells has a great importance. A number of cytotoxicity assays are currently available, each of them using a specific approach to detect different aspects of cell viability, such as cell integrity, proliferation and metabolic functions. The purpose of this study is to compare, under identical experimental conditions, three common cytotoxicity assays (ATP-lite, MTT and CCK-8 assays) in the assessment of the anti-proliferative effects of 5-fluorouracil (5-FU) and oxaliplatin (OHP) on three colon cancer cell lines (WiDr, SW620 and HT-29). Regarding 5-FU, the three assays were found to be significantly correlated with a moderate or high correlation coefficient, whereas in the case of OHP we found different outcomes among the assays. Our study demonstrates that the CCK-8 is the most sensitive assay for detecting changes of cell viability, suggesting that the viability measured in cells after drug exposure depends on several parameters like the drug used, the biological characteristics of the target cell and the specific approach employed by the method to detect distinct cell growth and metabolic functions.

Abstract
AIM Control of postoperative pain is one of the most important concerns for both the patients and the surgical team. In this regard the efficacy of wound infiltration with local analgesia and the most proper drugs to be used are not settled. We conducted our study trying to investigate this point in a prospective randomized double blinded manner. METHODS With inclusion criteria of: age (18-65 y), volume <90 mL, first time, no lymph node enlargement and exclusion criteria of: duration >90 min, incision length >10 cm, neck dissection decided during surgery and a postoperative complication within the first 24 hours. Sixty patients planned for total thyroidectomy under general anesthesia were enrolled in the study in three groups with twenty patients assigned randomly to each one: group (A) a control group in which no wound infiltration was done, group (B) in which preoperative wound infiltration with 10 mL bupivacaine 0.5% was done, and group (C) in which preoperative wound infiltration with 10 mL ropivacaine 0.75% was done. Postoperative pain was evaluated by Visual Analogue Score (VAS) with a scale of (0-10) at 1 hour, 4 hours, 8 hours and 16 hours. RESULTS The postoperative pain experienced by all the patients reached a maximum point at 1 hour postoperatively then started to decrease to be minimal at 8 hours and almost negligible at 16 hours. Ropivacaine group showed a statistically significant decrease in pain perception at 1 hour postoperatively (P=0.028), bupivacaine group showed also a decrease in pain perception at 1 hour but it was not statistically significant. At 4 hours of operation and after; neither ropivacaine nor bupivacaine showed an effect on pain perception. CONCLUSION The benefit of local wound infiltration with local analgesia in decreasing postoperative pain is limited to a short period after surgery in which the use of ropivacaine 0.75% is recommended over pubivaccaine 0.5%.

Abstract
BACKGROUND Fine needle aspiration (FNA) with cytologic evaluation is the most reliable tool for malignancy prediction in thyroid nodules, but cytologic diagnosis remains undetermined for 20% of nodules. AIM We investigated the diagnostic potential of a set of 6 marker genes to distinguish benign and malignant thyroid nodules. SUBJECTS AND METHODS The prospective study included 153 thyroid samples obtained by FNA of thyroid nodules from 151 patients (56 benign, 43 malignant, and 54 nodules with undetermined cytology). Gene expression was evaluated by quantitative realtime PCR and statistical analysis of data was performed. All samples were analyzed for V600E BRAF mutation. RESULTS A decrease in TTF3 and HGD1 expression was observed in malignant nodules with respect to benign ones, while an increase in PLAB expression was demonstrated in these nodules. The decision model was valid for 88 of 99 cases of benign and malignant nodules, with a total of 11 false positive or negative predictions. The obtained malignant/benign phenotype prediction was also valid for 37 of 54 cases of nodules with undetermined cytology with a total of 8 false positive and 9 false negative predictions. V600E BRAF gene mutation was demonstrated in 19/43 malignant nodules, in 0/56 benign nodules, and in 1/54 undetermined nodules. CONCLUSIONS The expression profiles of genes (TFF3, HGD1, and PLAB) allowed a good prediction for the differentiation of benign thyroid lesions and thyroid cancer starting from cells of FNA; however, this assay showed limitations when applied to discriminate thyroid nodules with undetermined cytology.

Abstract
BACKGROUND Data on the cardiovascular middle-term follow-up of patients with primary aldosteronism (PA) are scanty. AIM To detect the cardiovascular effects of surgery in patients with aldosterone (ALD)-producing adenoma (APA) and of pharmacotherapy in those with bilateral adrenal hyperplasia (BAH), a prospective study involving 60 consecutive patients with PA was performed. MATERIAL/ METHODS: Clinical, biochemical, and cardiovascular assessment was obtained before and after (31.5±4.4 months) surgery or proper medical treatment (32.1±5.0 months) in 19 and 41 patients, respectively. RESULTS As expected, plasma ALD normalized in all operated patients, while in the other group it did not change. Systolic and diastolic blood pressure decreased (p<0.001) after both treatments. However, absolute and percentage reduction was significantly more pronounced (p<0.01) in operated than in non-operated patients. Left ventricular (LV) mass showed significant reduction after surgery (LV mass g/m(2), p<0.0007; LV mass g/m(2.7), p<0.01), but no change after medical treatment, so that the differences between absolute and percentage values at follow- up were statistically significant (p<0.01) between groups. Basal LV mass/m(2.7) was positively associated with age (p<0.009), body mass index (p<0.0008), drug number (p<0.03), and ALD/plasma renin activity ratio (p<0.01). Allocating the patients according to plasma ALD and cardiac parameters, patients who presented ALD reduction during the study also had a decrement in cardiac mass (p<0.04). CONCLUSIONS Our data indicate that in patients with PA the removal of ALD excess by surgery in APA is effective in reducing blood pressure and in improving cardiac parameters, while anti-hypertensive therapy in BAH shows less positive impact on cardiovascular system.

Abstract
AIM Minimally invasive video-assisted thyroidectomy (MIVAT) and endoscopic thyroidectomy through areola (ETA) access are among the endoscopic approaches for thyroidectomy that have been perfected, but reports comparing the two are lacking. This study evaluated the safety, postoperative recovery, and patient satisfaction of MIVAT compared with ETA. METHODS This study included 119 patients undergoing MIVAT and 42 patients undergoing ETA from January 2006 to October 2009. Operative time, complications, postoperative recovery, cosmetic result, and patient satisfaction were analyzed. RESULTS The ETA group had a higher percentage of women (100% vs. 78.2%, P<0.05) and was younger (33.5 vs. 39 years, P<0.05). Thyroid volume (24.5 vs. 14.5 mL, P<0.001) and nodular diameter (26 vs. 22 mm, P<0.05) were larger in ETA group. The MIVAT group had a shorter operative time (28.2 vs. 112.8 minutes) and a lower rate of intraoperative (7.2 vs. 21.2 mL) and postoperative (0 vs. 80 mL, P<0.0001) blood loss. Rates of conversion and complications were similar. Postoperative pain at 12 hours was 1.9 in MIVAT vs. 3.1 in ETA (P<0.0001). Hospitalization was 1 day in the MIVAT group vs. 3.5 days in ETA (P<0.0001). Patient satisfaction was similar. CONCLUSION MIVAT and ETA showed similar results for safety, although ETA might be considered more invasive than MIVAT. Patients of both groups were equally satisfied with the cosmetic result. Differently from ETA, MIVAT allows total thyroidectomy to be performed also for malignant diseases. Although different, the two approaches were safe and reliable and both are valid options. Choice might depend on the surgeon's preference, thyroid size, type of disease, and the patient's expectation about cosmesis.

Abstract
BACKGROUND Although fine-needle aspiration cytology remains the mainstay of the preoperative workup of thyroid nodules, those with follicular proliferation still represent a diagnostic challenge. Real-time elastography (RTE) estimates the stiffness/elasticity of lesions and is regarded as a promising technique for the presurgical selection of thyroid nodules (including those with indeterminate cytology). AIM Our aim was to verify the potential role of RTE in the presurgical diagnosis of cancer in a large cohort of consecutive patients with follicular thyroid nodules. PATIENTS AND METHODS One hundred two patients were submitted to conventional ultrasonography and RTE evaluation before being operated on for thyroid nodule with indeterminate cytology (54% single nodules). Tissue stiffness on RTE was scored from 1 (greatest elasticity) to 4 (no elasticity). RESULTS At conventional ultrasonography examination, the nodules (median diameter 2.2 cm) were solid (cystic areas < 10%); microcalcifications were detected in 56% of them and a hypoechoic pattern in 64%. Elasticity was high in eight cases only (score 1-2) although low in 94 (score 3-4). Cancer was diagnosed in 36 nodules (35%), being associated with microcalcifications (P < 0.0001) and inversely related to nodule diameter (P < 0.01). Malignancy was detected in 50% of the nodules with RTE score 1-2 and in 34% of those with score 3-4. Therefore, either the positive (34%) or the negative predictive value (50%) was clinically negligible. CONCLUSIONS The current study does not confirm the recently reported usefulness of RTE in presurgical selection of nodules with indeterminate cytology and suggest the need for quantitative analytical assessment of nodule stiffness to improve RTE efficacy.

Abstract
BACKGROUND Surgery is the therapy of choice in primary hyperparathyroidism (PHPT), although other less invasive techniques have been used in the attempt to cure the disease. Recently, high-intensity focused ultrasound (HIFU), a totally non-invasive technique, has become available to cure solid tumors. AIM The aim of this pilot study has been to assess the safety and efficacy of HIFU in symptomatic patients with PHPT. MATERIAL AND METHODS Four out of 31 patients with surgical indications within a cohort of 47-screened patients with PHPT were considered eligible for the study. All patients accepted to participate and were submitted to HIFU treatment in a single session. One patient was submitted to surgery after HIFU treatment. Patients were followed-up for 12 months after the procedure. RESULTS A persistent or a partial remission of the disease, respectively, were obtained in 2 patients (50%), including the one who underwent surgery after HIFU treatment. Safety was assessed performing laryngoscopy in all patients after HIFU procedure. A transient vocal cord paralysis was observed in all patients treated by HIFU only. No permanent side effects were observed in the long term. CONCLUSIONS HIFU might be a promising technique in treating PHPT, provided that further development of the software decreases the rate of side effects and improves the short- and long-term efficacy.

Abstract
Adjuvant therapy has evolved to become the standard care of colon cancer, but the tumor capability of activating effective mechanisms of defence against both chemical and physical cytotoxic agents represents a serious obstacle to the successful therapy. Furthermore, the possibility to have an assay useful to measure the drug sensitivity of tumor cells could be of a great importance. As primary human colon cancer cultures from fresh tumor are technically difficult to obtain, experiments with human cancer cell lines remain essential to explore new adjuvant chemotherapy drugs, to investigate the individual responsiveness to the known agents, and particularly to clarify how these chemotherapeutic agents could be used in maximizing outcomes. In the present study we evaluate the cytotoxic effects of 5-fluorouracil (5-FU) and oxaliplatin (OHP) and of their pharmacological interaction in three human colon cancer cell lines (WiDr, HT-29 and SW620), by using an ATP luminescence assay (ATPlite; Perkin Elmer), displaying high sensitivity, linearity and reproducibility. Cell cycle, apoptosis and CD44 expression were investigated with flow cytometry. Our results show that the drug combinations inhibited the cell growth more than each drug alone in all colorectal cancer cell lines. Interestingly, the sequential exposure of OHP and 5-FU resulted in the most cytotoxic effect in all colon cancer cell lines, when compared to the simultaneous one. Our results focus on the powerful cytotoxic effect of 5-FU-OHP combination, when used in sequential exposure, suggesting interesting implications for a rational use of 5-FU, OHP combination in colon-rectal cancer therapy.

Abstract
About 20% of the total cells from primary breast tumors could generate palpable tumors in non-obese diabetic severe combined immunodeficient (NOD/SCID) immunocompromised mice. All the tumorigenic cells originate from a normal mammary stem cell. Human mammary stem cells are sensitive to oncogenic mutations and in mouse models they share similarities with breast cancer stem cells (BrCSCs). Tumorigenicity, invasion, progression and metastasization are further BrCSCs properties likely depending on their CD44+/CD24- phenotype. Local invasion and tumor metastasization seem to be facilitated by the epithelial to mesenchymal transition (EMT) program. This program may be reactivated from stable genetic alterations or through exposure of cancer cells to factors present in the surrounding micro-environment, or by an up-regulation of EMT-inducing transcription factors. One main explanation for resistance to treatment by cancer cells is that a rare subpopulation of cells in residual tumors with tumorigenic potential is intrinsically resistant to therapy. Consistent with this hypothesis, in human breast tumors, the subpopulation of tumor-initiating cancer cells with CD44(high)/CD24(low) cell surface-marker profile was found more resistant to cancer therapies (chemo, hormone and radiotherapy) than is the major population of more differentiated breast cancer cells. The reasons for CSC resistance to chemotherapy, hormone therapy and radiotherapy also have been examined and they opened new scenarios for cancer therapy.

Abstract
Thyroid surgery during the last century was characterized by a development of Kocher's concepts: through a relentless work of surgeons from all over the world thyroidectomy reached a standard of quality in terms of overall results which was unimaginable in the first half of the XX century. The flattering data collected in the literature until the 90's were all concordant in assuming that there would be little space for a real improvement in the quality standard of thyroid surgery. The introduction of laparoscopic surgery, though, changed very quickly the attitude of surgeons towards their operative behavior and countless new mini-invasive techniques were soon proposed for almost any field of surgery. In 1994, Gagner published the first series of laparoscopic adrenalectomies. Soon after, parathyroid adenomas seemed to offer an ideal field of application of these new surgical concepts. The first report of an endoscopic parathyroidectomy was in 1996. One year later other videoscopic procedures were described whose results seemed quite encouraging so as to push surgeons to try the same access and the same technique also for operations on thyroid. During the following decade several endoscopic or video-assisted approaches were proposed for the removal of thyroid gland. This paper aims to evaluate the results of minimally invasive thyroid and parathyroid surgery through an extensive review of the literature, in particular as far as minimally invasive video-assisted thyroidectomy is concerned.

Abstract
Currently stem cells are hypothesized to play a central role in the origin, spread and resistance to treatment of breast cancer. Common anticancer therapy is effective but transient, with tumor relapse and metastatic disease often occurring. For therapy to be more effective, debulking of differentiated tumors must occur followed by targeting of the remaining surviving often quiescent tumor stem cells. New therapeutics aimed at cancer stem cells are achieved through non immunological and immunological methods. The former include elective ABC drug transporters or the heat shock protein 90 inhibition, targeting the self-renewal signalling pathways or the EMT program, differentiation therapy, or other interventions to eliminate BrCSCs. The latter include targeting specific antigens expressed on BrCSCs, dendritic cells (DCs) based vaccination and blockers of the extrinsic signals at CSC niche. Here all these novel approaches related to breast cancer stem cells are described.

Abstract
OBJECTIVE To evaluate the risk of papillary thyroid carcinoma (PTC) at fine-needle aspiration (FNA) cytology in 34 120 patients. RESULTS False positive and false negative rates of FNA cytology were 1.2 and 1.8% in comparison with the histology in 3406 nodules from 3004 patients who underwent surgery. PTC (901 cases) was more frequent in solitary nodule (SN; 446/13 549, 3.3%) than in multinodular goiter (MNG; 411/19 923, 2%, chi(2)=48.8; P<0.0001), and in males (209/6382, 3.3%) than in females (648/26 945, 2.40%, chi(2)=15.58; P<0.0001). PTC prevalence in Graves' disease (GD; 13/286, 4.5%) and Hashimoto's thyroiditis (HT; 31/508, 6.1%) was higher than in SN, this difference being significant in HT (chi(2)=8.7; P=0.003), but not in GD (chi(2)=1.6; P=0.2). Using the multiple logistic regression analysis, independent risk predictors of PTC were determined, which were younger age (odds ratio (OR)=0.97, confidence interval (CI) 0.964-0.974; P<0.0001), male gender (OR=1.44, CI 1.231-1.683; P<0.0001), and SN versus MNG (OR=0.63, CI 0.547-0.717; P<0.0001). The individual risk predictivity was highly improved by including serum TSH in the prediction model, which was measured at FNA in 11 919 patients. CONCLUSION A cytology suspicious or indicative of PTC was associated with younger age, male gender, and solitary versus multiple nodularity. These clinical parameters, together with serum TSH, may allow formulation of an algorithm that could be usefully applied to predict the risk of PTC in individual patients when cytology does not give a diagnostic result.

Abstract
Aberrant accumulation of beta-catenin has been found in various types of human tumors. The aim of this study was to evaluate whether Wnt/beta-catenin signaling is activated in parathyroid carcinomas and adenomas. We studied 154 parathyroid tumors (18 carcinomas (13 with distant metastases), six atypical adenomas, and 130 adenomas). Three normal parathyroid tissues were used as control. Direct sequencing of exon 3 of the CTNNB1 gene showed absence of stabilizing mutations in all the tumors. Immunostaining of beta-catenin was performed in all carcinomas and in 66 adenomas (including three atypical). Normal parathyroid showed a homogeneous distinct outer cell membrane staining in the majority of cells and no nuclear staining. A weak cytoplasmic staining was observed in one case. All tumors showed negative nuclear staining. With the exception of one carcinoma, which had a negative membrane staining, all other samples showed a membrane staining which was similar to that of the normal parathyroid. beta-Catenin expression was heterogeneous with a range of positive cells between 5 and 80%, independently of tumor type. Our results suggest that the Wnt/beta-catenin signaling pathway is not involved in the development of parathyroid carcinomas and adenomas.

Abstract
The risk of papillary thyroid cancer (PTC) is related to serum TSH, and the development of thyroid autonomy by reducing TSH levels decreases the frequency of PTC in patients with nodular goiter. Our aim was to investigate the effect of L-thyroxine (LT(4)) on the frequency of PTC diagnosed by cytology in a large series of patients with nodular goiter untreated (n=20 055) or treated with L-T(4) (n=7859). L-T(4)-treated patients with respect to untreated patients presented significantly lower serum TSH (median, interquartile range: 0.30 muU/ml, 0.08-0.62 microU/ml versus 0.70 muU/ml, 0.38-1.14 muU/ml; P<0.0001) and prevalence of PTC (3.2 vs 5.1%; P<0.0001). The frequency of PTC was closely related to serum TSH, with it being lowest in patients with TSH below the normal range (<0.4 muU/ml; 189/10 059, 1.9%) and highest in patients with TSH above the normal range (>3.4 muU/ml; 21/127, 16.5%), also showing a progressive increase from the lower to the upper quartile of normal range. A significantly higher proportion of L-T(4)-treated patients (6650/7859, 84.6%) had serum TSH below the median (0.90 muU/ml) with respect to untreated patients (12,599/20,055, 62.8%; chi(2) P value <0.0001), with it being included in the range of TSH associated with a lower frequency of PTC. The relationship between serum TSH and frequency of PTC was unrelated to the type of nodularity (solitary versus multinodular) and was not age dependent. In conclusion, patients with nodular goiter, treatment with L-T(4) is responsible for the reduction of serum TSH and is associated with a decreased frequency of PTC.

Abstract
Forty-six consecutive patients who underwent total parathyroidectomy (tPTX) for hyperparathyroidism associated with end-stage kidney disease (CKD5) in a University Hospital from 1990 to 1999 were included in a long-term observational study. Outcome parameters included symptoms (bone pain, pruritus and muscle weakness evaluated by visual analog scales [VAS]) and laboratory data (intact parathyroid hormone [iPTH], total calcium, and alkaline phosphatase) assessed before, shortly postoperatively and then at a later time point: 40 patients were on maintenance hemodialysis and six on conservative medical therapy. Forty-four patients had four glands removed, while only three glands were found in the remaining two. Perioperative complications consisted of acute symptomatic hypocalcemia in 10 (22%) patients and non-specific complaints in three (7%). No laryngeal nerve palsies occurred. After a median follow-up of eight years, 43 subjects were evaluated: 37 (86%) were cured, three (7%) had persistent and three (7%) recurrent disease. Eleven patients underwent successful renal transplantation and 23 died during the period of observation. iPTH decreased from a mean of 1084+/-505 pg/ml to 120+/-381 pg/ml (p < 0.0001). No subsequent bone fractures, persistent bone pain or disability were reported; this includes patients who later received a functioning renal graft. tPTX was able to correct hyperparathyroidism in most of the patients and was associated with a low long-term relapse rate. iPTH levels remained low in 17 cases without symptoms and no clinically significant side effects. The beneficial effects of tPTX occurred in the majority of patients while renal transplantation was performed in a minority of patients. tPTX should be considered a safe and successful procedure for the treatment of severe secondary hyperparathyroidism associated with chronic kidney disease.

Abstract
During the 1990s, with the general tendency to develop minimally invasive operations, an endoscopic approach has been applied to neck surgery for both parathyroidectomy and thyroidectomy. The most widely spread minimally invasive technique for thyroidectomy is minimally invasive video assisted thyroidectomy (MIVAT), described and developed for the first time at our institution in 1998. Ideal candidates for MIVAT are patients with a thyroid volume lower than 25ml with nodules smaller than 35 mm. Consequently, MIVAT will present restricted indications, being suitable only for the treatment of about 10-15% of the whole standard surgical case load. Thus, together with small follicular lesions, "low risk" papillary carcinoma will result the main indication for MIVAT, being this small cancer usually harboured in normal glands of young females. On the other hand, in case of locally invasive carcinomas and/or lymph node metastasis the procedure must be immediately converted to the conventional technique. MIVAT also is not indicated for the treatment of medullary and anaplastic carcinomas. Recent prospective randomized studies clearly demonstrate that MIVAT allows achieving same clearance at the thyroid bed level and same outcome as conventional technique, when dealing with "low risk" papillary carcinoma. At the same time, patients can benefit from the main advantages of this minimally invasive technique: lower postoperative pain, faster postoperative recovery and excellent cosmetic outcome.

Abstract
INTRODUCTION Niemann-Pick disease (NPD) types A and B are lipid storage disorders. NPD type A is a fatal disorder of infancy. Type B is a non-neuronopathic form observed in children and adults. It is associated with enlargement of the liver, spleen, or both, and nodular splenomegaly may be detected with ultrasound. METHODS A 21-year-old female was admitted to the Emergency Room with fever, pharyngitis, and left upper quadrant abdominal pain. Labwork revealed anemia, thrombocytopenia, increased levels of AST, ALT, GGT, AF, LDH, triglycerides, and total cholesterol and low levels of HDL-cholesterol. PCR blood assays for CMV and EBV were both negative. Chest X-ray was unremarkable. Transabdominal B-mode ultrasound (US) revealed splenomegaly (long axis: >22 cm), an irregular subcapsular hypoechoic lesion in the superior pole that was consistent with splenic infarction, and multiple round highly echogenic nodes measuring 1-5 cm in diameter. Contrast-enhanced ultrasonography (CEUS) was performed using SonoVue(®) (Bracco). RESULTS The presence of a splenic infarction was confirmed. The nodular lesions showed arterial-phase enhancement with late parenchymal phase wash-out. (18)F-FDG-PET revealed splenic nodular uptake. Primary splenic lymphoma was suspected, and the patient underwent open splenectomy. The diagnosis was type B NPD with splenic hemangiomas. DISCUSSION CEUS confirmed the diagnosis and extent of splenic infarction, but the nodular atypical enhancement pattern together with nodular (18)F-FDG-PET uptake was misleading, suggesting as it did lymphoproliferative involvement of the spleen.

Abstract
AIM To review and to update the management protocols in thyroid surgery proposed two years ago by 1st Consensus Conference called on the topic by the Italian Association of Endocrine Surgery Units (UEC Club). METHOD The 2nd Consensus Conference took place November 30, 2008 in Pisa within the framework of the 7th National Congress of the UEC Club. A selected board of endocrinologists and endocrine surgeons (chairmans: Paolo Miccoli and Aldo Pinchera; speaker: Lodovico Rosato) examined the individual chapters and submitted the consensus text for the approval of several experts. This plain and concise text provides the rationale of the thyroid patient management and wants to be the most complete possible tool for the physicians and other professionals in the field. CONCLUSIONS The diagnostic, therapeutic and healthcare management protocols in thyroid surgery approved by the 2nd Consensus Conference are officially those proposed by the Italian Association of Endocrine Surgery Units (UEC Club) and are subject to review by two years.

Abstract
Thyroid carcinoma can be divided in two main groups, differentiated, with a good prognosis and an average 10 years survival ranging from 70% to 95%, and undifferentiated which is lethal in few months. Differentiated thyroid carcinoma can be distinguished in those variants coming from follicular cells (papillary and follicular) and those from C cell (medullary carcinoma). Surgical approach represents the first step in the treatment of thyroid carcinoma. Minimally-invasive endoscopic technique can be applied only to a minority of case, the so called ''low risk'' carcinoma according to AGES and AMES criteria. During the last ten years many different endoscopic approaches have been proposed for the treatment of thyroid carcinoma and the minimally invasive videoassisted (MIVAT) by Prof Miccoli is undoubtly the one which resulted to be the most successful and spread all over the world. Through a 1.5 cm central skin incision 2 cm above the sternal notch MIVAT allows to perform a total thyroidectomy for low risk papillary carcinoma with a completeness similar to that of conventional thyroidectomy. Using the same central access it is also possible to perfom a prophylactic central neck dissection for RET gene positive carriers. A lateral neck minimally invasive videoassisted lymphadenectomy is under development for those patients with low risk papillary carcinoma and isolated lateral lymph node metastasis.

Abstract
Minimally invasive video-assisted thyroidectomy (MIVAT) was introduced in our department in 1998. The procedure is based on a unique incision in the central neck, 2 cm above the sternal notch, using small conventional retractors and 2-mm reusable instruments. Hemostasis is achieved by using a Harmonic scalpel. 1,320 (1,136 female and 184 male, ratio 4:1) patients have undergone MIVAT since June 1998. Lobectomy was carried out in 421 patients, while 899 patients underwent total thyroidectomy. In 21 cases (RET oncogene mutation carriers), MIVAT was associated with central compartment lymph node clearance. Mean operative time of lobectomy was 32.3 min (range 20-120 min); for total thyroidectomy it was 44.1 min (range 30-130). Mean time for video-assisted central compartment lymphadenectomy was 57 min. Conversion to standard cervicotomy was required in 30 cases (2.2%); operative complications included transient unilateral recurrent nerve palsy in 35 cases (2.65%) and definitive unilateral recurrent nerve palsy in 15 cases (1.13%). Thirty-eight patients exhibited hypoparathyroidism, which corresponds to 4.2% of total thyroidectomies performed, but only 2 showed permanent hypoparathyroidism. MIVAT can be considered a safe operation offering significant cosmetic advantages and has possible new promising indications such as prophylactic thyroidectomy in RET gene mutation carriers.

Abstract
INTRODUCTION The incidence of adrenal incidentalomas is reported to be up to 30% in the current literature; nevertheless, in some patients undergoing surgery, a final diagnosis of non-adrenal origin of the mass is performed. In this paper we present our experience of 13 patients with unexpected histological findings of lesions diagnosed in the adrenal region. PATIENTS AND METHODS From June 1986 to December 2004, 420 patients underwent adrenalectomy in our Department. Since the introduction of videolaparoscopic technique in 1993, 228 adrenalectomies have been performed videolaparoscopically. Pre-operative diagnosis was: incidentaloma (34.0% of patients), Conn's adenoma (29.0%), Cushing's adenoma (13.9%), pheochromocytoma (8.8%), suspicious metastasis (7.3%), Cushing's disease (6.0%), other (1.0%). RESULTS Final histology revealed an unexpected diagnosis of non-adrenal origin of the mass in 13 patients (3.1%). Histology demonstrated a benign neurogenic tumor in 10 patients. In the other 3 patients diagnosis was respectively of lymphnode, hemangioma and a gastric metastasis of melanoma. Five patients out of 7 had a successful laparoscopic resection of the lesion. Mean operative time in this group was higher compared to laparoscopic resection for adrenal lesion (95.3 min vs 73.2 min). CONCLUSION A small percentage of our patients (3.1%) demonstrated unexpected findings of the lesion pre-operatively misinterpreted as an adrenal mass. Despite a complete pre-operative assessment, adrenal lesions might reveal a different origin, increasing the surgical challenge as well as the morbidity for the patient.

Abstract
INTRODUCTION Nodular lesions within the neck may origin from several structures. A misdiagnosed origin may expose the surgeon to inappropriate procedures. These lesions are paradoxically frequent in high specialised centre for endocrine surgery. PATIENTS AND METHODS In the year 2006, three patients were first admitted to our department with a diagnosis of thyroid nodule (1) or lymphatic metastases of thyroid carcinoma (2). The first patient had ultrasound (US) and Tc-99-m scan orienting for thyroid nodule. The two other patients, presented with lateral neck lesion in ipsilateral sincronous and previous diagnosis of papillary thyroid carcinoma, respectively, with US and computed tomography scan confirmed lesion but with a FNA cytology negative for tumoural cells. RESULTS All three patients underwent surgical exploration. In the first two cases, a whitish tender nodule (4 and 4.5cm), cleavable from surrounding structures, was removed with final histology of Schwannoma and Paraganglioma, respectively. Both patients experienced Bernard Horner Syndrome. In the last patients, a firm grey nodule of 5cm strictly adherent to muscular planes was removed with diagnosis of Castleman's Disease. CONCLUSIONS Nodular neck lesions mimicking a thyroid pathology (thyroid nodules or metastatic lymph nodes) are rare but can represent a tough challenge for surgeons who might fall into incorrect surgical approaches, resulting in high morbidity. Pre-operative work-up would help the surgeon to obtain the correct diagnosis, thus, to follow the better surgical approach. Nevertheless, a careful approach would be used for that neurogenic tumour amenable of resection without jeopardising nervous structures.

Abstract
AIM The aim of the study was to draw up a management protocol in parathyroid surgery promoted by the Italian Association of Endocrine Surgery Units (UEC Club), based on the guidelines of the main international scientific societies and shared by the experts and applied by the operators in the sector. METHODS AND CONSENSUS The management protocols, already presented in 2003, on the occasion of the current review were examined by the 1st Consensus Conference called on the topic by the Italian Association of Endocrine Surgery Units (UEC). The Conference comprised two distinct sessions, the first in November 2006 within the framework of the 5th National Congress of the UEC Club in Verona, and the second in September 2007 within the framework of the 10th Multidisciplinary Scanno Prize Meeting. A selected board of endocrinologists and endocrine surgeons examined the individual chapters and submitted the consensus text for the approval of several experts. CONCLUSIONS The diagnostic, therapeutic and healthcare management protocols in parathyroid surgery approved by the 1st Consensus Conference are officially those proposed by the Italian Association of Endocrine Surgery Units (UEC Club) and are subject to review by October, 2009.

Abstract
INTRODUCTION Existing trials investigated the impact of medical treatment of thyroid disorders on health-related quality of life (QOL) and psychiatric symptoms. The aim of this prospective study is to analyze the impact of thyroid surgery on QOL and severity of psychiatric symptoms. MATERIALS AND METHODS Forty-seven patients undergoing thyroid surgery (TS) were assessed before thyroidectomy (T0) and 37 also after surgery, >or=6 months after euthyroidism was achieved (T1). QOL and psychiatric symptoms were evaluated at T0 and T1 using the Medical Outcomes Study Short Form Survey (SF-36) and the Symptom Checklist-90 (SCL-90-R). Scores at T0 were compared with those of patients undergoing surgery for non-thyroidal disease and the SF-36 scores were also compared with the normative Italian sample. Changes in QOL and psychiatric symptoms between T0 and T1 were also examined. RESULTS Health-related QOL in TS patients before surgery was poorer than in the comparison group on the SF-36 mental component summary measure and social functioning. Mental health improved significantly after surgery but social functioning remained markedly impaired. A significant reduction in the severity of psychiatric symptoms was observed. DISCUSSION Our results indicate that even long after euthyroidism is achieved after surgery, patients show a significant improvement of mental health and a reduction of psychiatric symptoms. Nevertheless, patients continue to have a poorer QOL compared to the Italian normative sample.

Abstract
The aim of this study was to determine the protein pattern of human thyroid fine needle aspiration fluid (FNA) using a proteomic approach. FNA proteins were separated using 2-dimensional gel electrophoresis (2DE), digested and then analyzed by peptide mass fingerprinting. For the first time, we provided an image of the protein components of the FNA, in which approximately 220 protein spots can be identified. The proteome analysis revealed a specific fingerprint of FNA with proteins appertaining to various functional systems. Our preliminary results of FNA protein pattern could be a starting point in studying the presence of potential markers implicated in thyroid diseases.

Abstract
The onset of cervicoscopy dates back to the first endoscopic parathyroidectomy in 1996. This operation, along with its several variants, has become a valid option widespread in many important centres. Later on, endoscopic or video assisted thyroidectomy was introduced in spite of the limits imposed by the mass of the gland to remove. It is indicated for a minority of patients for this reason but both parathyroidectomy and thyroidectomy showed some important advantages with respect to conventional surgery, advantages demonstrated also in prospective studies. They are mainly represented by a better cosmetic outcome and a less distressful postoperative course. These approaches proved to be safe and feasible in any surgical background: their complication rate is the same as traditional open surgery in the neck. Very promising seems to be the videoscopic access to neck lymph nodes (central and lateral compartments) whereas other fields of application such as carotid artery surgery and spine surgery still remain object of experimental studies. As far as the lateral neck dissection is concerned the technique is going to be standardized in our centre as a variant of the well known video assisted approach adding a 5 mm trocar placed in the supraclavicular space. By consequence, cervicoscopy has to be considered an important surgical tool which can be further improved but which also has an excellent potentiality.

Abstract
INTRODUCTION An evaluation of PTH levels during thyroid surgery may reflect the functional status of the parathyroids and be useful in identifying patients at risk for hypocalcemia. This study aims to monitor the parathyroid function during total thyroidectomy through intra-operative serial samples for calcium and PTH. MATERIALS AND METHODS Forty-seven patients undergoing total thyroidectomy for different diseases were selected for the study. Patients underwent serum PTH and calcium sampling at the induction of anesthesia (T0) and after the first (T1) and the second (T2) lobectomy. Serum calcium was also drafted 24 h after the operation. RESULTS Mean PTH at T0, T1, and T2 was, respectively: 32.1 pg/ml, 19.6 pg/ml, and 11.5 pg/ml. PTH was significantly higher at T0 when compared to T1 (p<0.0001). It was also significantly higher at T1 than at T2 (p<0.0001). At T1 PTH levels were below the normal range in 20/47 cases (42.5%) and at T2 in 31/47 cases (66%). Twenty-four h after surgery, 8 patients (17%) demonstrated a biochemical hypocalcemia. A PTH value at T0 in the upper (>70 pg/ml) or in the lower (<20 pg/ml) limits of the normal range was statistically related to post-operative hypocalcemia (p=0.017). DISCUSSION The study seems to confirm that serum PTH during thyroidectomy does not represent a sensitive tool in precociously identifying hypocalcemic patients. Nevertheless, before surgery, a PTH concentration at the higher or lower normal limit may help to identify patients "at risk" of developing hypocalcemia.

Abstract
PURPOSE This study was performed to evaluate the accuracy of multidetector computed tomography (MDCT) in detecting parathyroid lesions in patients with primary hyperparathyroidism. MATERIALS AND METHODS We included 60 patients with primary hyperparathyroidism. Preoperative first-line examinations revealed negative and doubtful ultrasound (US) findings in 34 and 26 cases, respectively, and negative, doubtful and positive scintigraphic findings in 19, 20 and 21 cases, respectively. CT findings were compared with the surgical results. RESULTS CT examination was positive in 35 cases, negative in 15 cases and doubtful in ten cases. Forty out of 60 patients underwent surgery, and 39 lesions (37 adenomas, two primary hyperplasias) were identified. Surgery was negative in two cases. In eight cases, lesions had ectopic location. Surgery confirmed the CT findings in 23 positive cases. In 8/10 doubtful cases, surgery confirmed the location of the lesion in five cases, identified the ectopic location of lesions in two cases, and was negative in one case. In 9/15 cases with negative CT findings, surgery identified the lesion in eight cases. Sensitivity, specificity and diagnostic accuracy values were 78%, 25% and 73%, respectively. CONCLUSIONS MDCT is an accurate second-line diagnostic technique in the detection of parathyroid lesions, allowing exploration of the entire cervical and mediastinal regions.

Abstract
Early onset of primary hyperparathyroidism (PHPT) and multiglandular involvement suggest a familial form in which germline mutation of a PHPT-related gene(s) and a somatic event at the same locus can be often demonstrated. We investigated the involvement of multiple endocrine neoplasia type 1 (MEN1) and HRPT2 genes in a 39-year-old man with recurrent PHPT. PHPT was firstly diagnosed at the age of 21 and the patient had two recurrences separated by extended periods of normocalcemia. This unusual history prompted us to investigate other family members and study the MEN1 and HRPT2 genes. An HRPT2 germline missense mutation in exon 3 (R91P) was found in the index case, which was associated with different HRPT2 somatic alterations in each of the three examined parathyroid tumors. These findings are consistent with Knudson's 'two hit' concept of biallelic inactivation of classical tumor suppressor genes. Screening of 15 asymptomatic relatives was negative for the R91P germline mutation. All the three abnormal parathyroid specimens showed cystic features at histology and were negative for parafibromin immunostaining. In one specimen, diffuse parafibromin staining was evident in a rim of normal parathyroid tissue surrounding the adenomatous lesion. Our study shows that different somatic genetic events at the HRPT2 locus are responsible for the asynchronous occurrence of multiple adenomas in a patient carrying an HRPT2 germline mutation. The finding of diffuse parafibromin staining in a rim of normal parathyroid tissue, but not in the contiguous adenomatous lesion, reinforces the concept that loss of parafibromin expression is responsible for the development of parathyroid tumors in this setting.

Abstract
BACKGROUND Quick intraoperative parathormone assay (qPTHa) during paratyroidectomy has become a standard procedure for patients with primary hyperparathyroidism (PHPT). This paper aims to compare endoscopic bilateral neck exploration (BE) versus focused parathyroidectomy plus qPTHa during minimally invasive video-assisted parathyroidectomy (QM). The endpoints of the study are the mean operative time and outcome of the surgical procedure (PTH and calcemia normalization at one and six months postoperatively). METHODS Forty patients with PHPT, positive to preoperative localization studies (ultrasonography evaluation and (99)Tc-MIBI scan) for a single parathyroid adenoma, were randomly allotted into two groups. In the first group (QM), 20 patients (17 women, three men, mean age 57.6 years) underwent focused endoscopic parathyroidectomy (MIVAP tecnicque) plus qPTHa . In the second group (BE) 20 patients (17 women, three men, mean age 59.6 years) underwent endoscopic parathyroidectomy plus bilateral exploration in order to check the integrity of the remaining glands. RESULTS There were no significant differences between groups at baseline. No conversion to cervicotomy was required. No postoperative complications were reported. The mean operative time was 32.0 vs 33.1 min [BE and QM group respectively, p = not significant (ns)]. A second macroscopically enlarged gland was removed in four patients in the BE group. Only one out of four glands was reported to be hyperplastic in the final histology. All patients were discharged on the first postoperative day. Calcemia levels were normalized in all patient of both groups, despite persistently high level of serum PTH in one patient in the QM group. CONCLUSIONS BE can be performed endoscopically, avoiding both the time necessary for qPTHa and its cost, with the same effectiveness, but might in few cases lead to the unjustified removal of parathyroid glands slightly enlarged but not necessarily pathologic.

Abstract
Short-stay thyroid surgery (<24 h hospital stay) is becoming increasingly popular but some potentially lethal complications are considered strong arguments against shortening hospitalization after thyroidectomy. The authors reviewed the data of 1,571 patients undergoing one-day thyroid surgery over a 3-year period to determine safety and patient satisfaction. There were 1,244 females and 327 males. Mean age was 43 years. Patient satisfaction was evaluated by a questionnaire given on discharge, while post-discharge surgical recovery was analyzed by the PSR scale. Total thyroidectomy was performed in 1,119 patients (71%), hemithyroidectomy in 450 (29%), isthmusectomy in 2. Morbidity occurred in 152 patients (9.6%). Surgical complications were transient hypocalcemia in 112 cases and permanent hypoparathyroidism in 3; monolateral transient nerve palsy occurred in 10 cases, bilateral in 3; definitive monolateral recurrent palsy in 4 cases. Bleeding requiring re-intervention occurred in 10 cases, wound complications in 5 cases, and intraoperative tracheal lesion in 1 patient. Among complicated patients, 129 (84.8%) were treated after discharge as outpatients. Conversion to inpatient treatment occurred in 28 patients (1.7%) (25 for surgical reasons). Four patients (0.2%) required hospital readmission. Patients were very satisfied in 84.2%, satisfied in 9.5%, poorly satisfied in 4.3%, completely unsatisfied in 2%. Postoperative recovery mean score by PSR scale resulted in 85.14% (0-100%). Our results confirm that the one-day surgery model is safe, effective, and highly agreeable in patients undergoing surgery for thyroid disease.

Abstract
AIMS The utilization of fine needle aspiration (FNA) biopsy is an accurate and cost-effective method in the diagnosis of thyroid diseases. However, the non-diagnostic cases and cases of suspicious carcinoma remain a dilemma, and in these cases thyroidectomy is usually recommended, even if only 15-20% of these patients really need a thyroidectomy. To avoid unnecessary surgical treatment, frozen section (FS) is usually performed. This method is well recognized, but is not useful for the diagnosis of follicular lesions. Therefore, many authors have tried to increase the specificity and sensibility of intraoperative examination, supporting it with an intraoperative cytological technique (IC). To clarify the role of intraoperative exam (FS and IC), also comparing to FNA, we have reviewed our own experiences. METHODS In a period covering 6 years (2000-2005), FS was performed in 1,472 cases out of 11,420 total thyroidectomy operations. FS diagnosis and definitive diagnosis, were reviewed and confirmed, moreover, FNA diagnosis and definitive diagnosis were also considered and all intraoperatory cytological slides were reviewed. Diagnostic accuracy was assessed for FNA and FS with or without intraoperative cytology. We compared 1,472 FS diagnoses with their definitive histological diagnosis; 728 FNA out of 1,472 patients with definitive histological diagnosis, and 564 FS associated with IC out of 1,472 patients with definitive diagnosis. RESULTS The diagnostic accuracy of these three methods were, respectively, 88.8%, 88.8% and 95.7%. CONCLUSION We can assert that FS associated with IC remains the most accurate technique in the surgical management of thyroid nodules.
