Abstract
INTRODUCTION Acute appendicitis is a common and time-sensitive surgical emergency, requiring rapid and accurate diagnosis and management to prevent complications. Artificial intelligence (AI) has emerged as a transformative tool in healthcare, offering significant potential to improve the diagnosis and management of acute appendicitis. This review provides an overview of the evolving role of AI in the diagnosis and management of acute appendicitis, highlighting its benefits, challenges, and future perspectives. EVIDENCE ACQUISITION We performed a literature search on articles published from 2018 to September 2023. We included only original articles. EVIDENCE SYNTHESIS Overall, 121 studies were examined. We included 32 studies: 23 studies addressed the diagnosis, five the differentiation between complicated and uncomplicated appendicitis, and 4 studies the management of acute appendicitis. CONCLUSIONS AI is poised to revolutionize the diagnosis and management of acute appendicitis by improving accuracy, speed and consistency. It could potentially reduce healthcare costs. As AI technologies continue to evolve, further research and collaboration are needed to fully realize their potential in the diagnosis and management of acute appendicitis.

Abstract
A task force of the United Italian society of Endocrine Surgery (SIUEC) was commissioned to review the position statement on diagnostic, therapeutic and health‑care management protocol in thyroid surgery published in 2016, at the light of new technologies, recent oncological concepts, and tailored approaches. The objective of this publication was to support surgeons with modern rational protocols of treatment that can be shared by health-care professionals, taking into account important clinical, healthcare and therapeutic aspects, as well as potential sequelae and complications. The task force consists of 13 members of the SIUEC highly trained and experienced in thyroid surgery. The main topics concern clinical evaluation and preoperative workup, patient preparation for surgery, surgical treatment, non-surgical options, postoperative management, prevention and management of major complications, outpatient care and follow-up.

Abstract
The surgical treatment of the intermediate-risk DTC (1-4 cm) remains still controversial. We analyzed the current practice in Italy regarding the surgical management of intermediate-risk unilateral DTC to evaluate risk factors for recurrence and to identify a group of patients to whom propose a total thyroidectomy (TT) vs. hemithyroidectomy (HT). Among 1896 patients operated for thyroid cancer between January 2017 and December 2019, we evaluated 564 (29.7%) patients with unilateral intermediate-risk DTC (1-4 cm) without contralateral nodular lesions on the preoperative exams, chronic autoimmune thyroiditis, familiarity or radiance exposure. Data were collected retrospectively from the clinical register from 16 referral centers. The patients were followed for at least 14 months (median time 29.21 months). In our cohort 499 patients (88.4%) underwent total thyroidectomy whereas 65 patients (11.6%) underwent hemithyroidectomy. 151 (26.8%) patients had a multifocal DTC of whom 57 (10.1%) were bilateral. 21/66 (32.3%) patients were reoperated within 2 months from the first intervention (completion thyroidectomy). Three patients (3/564) developed regional lymph node recurrence 2 years after surgery and required a lymph nodal neck dissection. The single factor related to the risk of reoperation was the histological diameter (HR = 1.05 (1.00-1-09), p = 0.026). Risk stratification is the key to differentiating treatment options and achieving better outcomes. According to the present study, tumor diameter is a strong predictive risk factor to proper choose initial surgical management for intermediate-risk DTC.

Abstract
Thyroid ultrasonography (US) is the gold standard for thyroid imaging and its widespread use is due to an optimal spatial resolution for superficial anatomic structures, a low cost and the lack of health risks. Thyroid US is a pivotal tool for the diagnosis and follow-up of autoimmune thyroid diseases, for assessing nodule size and echostructure and defining the risk of malignancy in thyroid nodules. The main limitation of US is the poor reproducibility, due to the variable experience of the operators and the different performance and settings of the equipments. Aim of this consensus statement is to standardize the report of thyroid US through the definition of common minimum requirements and a correct terminology. US patterns of autoimmune thyroid diseases are defined. US signs of malignancy in thyroid nodules are classified and scored in each nodule. We also propose a simplified nodule risk stratification, based on the predictive value of each US sign, classified and scored according to the strength of association with malignancy, but also to the estimated reproducibility among different operators.

Abstract
INTRODUCTION Impaired wound healing represents a common operative complication after kidney transplantation. This problem seems to be affected by factors related to surgical technique, drugs, and patient/graft peculiarities. PATIENTS AND METHODS From January 2000 to December 2007, 350 consecutive kidney transplantations were performed in a population of nondiabetic patients. We evaluated the influence of various factors on impaired wound healing. RESULTS Among 350 kidney transplantation patients, we observed 54 cases (15.43%) of impaired healing of the surgical incision: 36 (10.29%) with first level and 18 (5.14%) with second level wound complications. Factors related to complications were overweight and delayed graft function. Cyclosporine and tacrolimus had similar effects. However, all patients developing second level complications showed more risk factors. In our experience, postoperative lymphocele did not occur as an unique factor but became a significant risk factor when associated with another one. Patients who did not have reconstruction of the muscle layers showed a greater incidence of incisional complications. CONCLUSION Impaired healing of the surgical incision more or less seriously influenced outcomes of transplanted patients. This complication was common and usually related to the presence of more than one risk factor.

Abstract
PURPOSE Percutaneous radiofrequency thermal ablation (RTA) was reported as an effective tool for the management of thyroid nodules (TNs). The aim of this study was to investigate the effects of RTA and to establish whether they were treatment-related by comparison with a matched, untreated control group. PATIENTS AND METHODS The study population included 40 patients with compressive TNs: 22 had nontoxic TNs, and 18 had toxic TNs and were treated with methimazole. In all patients, a fine-needle aspiration cytology was performed to exclude a thyroid malignancy. STUDY DESIGN Twenty patients were treated with RTA (group A), and 20 others did not receive any treatment (group B). At baseline, age, gender, and TN features did not differ significantly between groups. All patients were clinically, biochemically, and morphologically evaluated at baseline and after 1, 3, 6, and 12 months. RESULTS TN volume significantly decreased in group A (1.8 ± 0.3 ml at 12 months vs. 13.3 ± 1.8 ml at baseline; P < 0.0001) and remained stable in group B [11.7 ± 1.5 ml at 12 months vs. 11.2 ± 1.5 ml at baseline; P = not significant (NS)]. At 3-, 6-, and 12-month evaluations, TN volume was significantly lower in group A than in group B (P < 0.005). At the end of the follow-up, pressure symptoms were improved in all patients in group A but persisted unchanged in group B. In group A, hyperthyroidism completely recovered in 40% and improved in 40% of patients with toxic TNs, whereas it persisted in all patients with toxic TNs in group B. RTA was safe and well tolerated in all patients. CONCLUSIONS RTA induced a marked TN volume shrinkage resulting in parallel improvement of pressure symptoms. In most patients with toxic TNs, hyperthyroidism significantly improved as well. RTA may represent a valid therapeutic approach in patients with TNs not receiving conventional treatments.

Abstract
Ischemic steal syndrome (ISS) is a complication that can occur after the construction of a vascular access for hemodialysis. It is characterized by ischemia of the hand caused by marked reduction or reversal of flow through the arterial segment distal to the arteriovenous fistula (AVF). The diagnosis of hand ischemia is based on physical examination, but imaging studies are very useful for detecting the true cause of ischemia and for selecting an appropriate therapeutic strategy. In this report, we describe an uncommon cause of ISS in a patient on hemodialysis. The ischemia was caused by the presence of undetected flow through an older AVF on the same arm as the AVF used for dialysis. The unsuspected "steal" was disclosed by color Doppler examination of the vascular bed of the patient's left arm. Dynamic Doppler studies then played a fundamental role in the decision to ligate the distal radio-cephalic AVF. The procedure led to the complete relief of ischemic symptoms.

Abstract
INTRODUCTION Impaired healing of the surgical incision represents a common complication after kidney transplantation. We led a retrospective study seeking to understand the factors linked to these complications and reasons for their reduction during the last year. PATIENTS AND METHODS From January 2000 to April 2004, 170 consecutive kidney transplantations were performed in a homogenous patient population. We evaluated the influence of following factors to determine impaired healing of the incision: antirejection drugs, overweight/obesity, age, delayed graft function (DGF), diabetes, and abdominal wall reconstruction technique. RESULTS Among 165 patients we observed 26 (15.76%) cases of impaired healing of the surgical incision: 17 (65,38%) with first-level and nine with second-level wound complications. CONCLUSIONS Impaired healing of the surgical incision influences the outcome of kidney transplant patients. In our study we observed that cyclosporine and tacrolimus similary affected the incision's healing. It was not possible to evaluate the role of basiliximab. A univariate analysis of the factors related to complications revealed overweight and DGF. However, all patients developing second-level complications showed more risk factors. Patients who had not had reconstruction of the muscle layers showed a greater incidence of surgical complications, whereas patients who had skin sutured with an intradermic technique did not show an increased risk.

Abstract
The relation between young surgeons and transplantation has always been a "love and hate" one. Until a few years ago this branch of surgery was seen as pioneering, with extreme and and extensive training, and was reserved to few elected members. Nowadays things are different. In this article we try to understand the true reasons that young Italian surgeons avoid transplantation surgery.

Abstract
To investigate the relationships between the GH-IGF-I axis and the atherosclerotic profile, we designed this open, observational, prospective study. Peak GH after GHRH+arginine (ARG) test, serum IGF-I and IGF binding protein-3 (IGFBP-3), lipid profile, homeostasis model assessment (HOMA) index and intima-media thickness (IMT) at common carotid arteries were measured in 174 healthy individuals (92 women, 82 men, aged 18-80 yr). Exclusion criteria for this study were: 1) body mass index (BMI) > or = 30 kg/m2; 2) personal history of cardiovascular diseases; 3) previous or current treatments of diabetes or hypertension; 4) previous corticosteroids treatment for longer than 2 weeks or estrogens for longer than 3 months; 5) smoking of more than 15 cigarettes/day and alcohol abuse. Subjects were divided according to age in decade groups from < 20 to > 70 yr. BMI increased with age, as did systolic and diastolic blood pressures, although they remained in the normal range. The GH peak after GHRH+ARG test was significantly higher in the subjects aged < 20 yr than in all the other groups (p < 0.01), but was similar in the remaining groups. An inverse correlation was found between the IGF-I z-score and total/HDL-cholesterol ratio (p = 0.02) and mean IMT (p = 0.0009); IGFBP-3 z-score and mean IMT (p = 0.043); IGF: IGFBP-3 molar ratio and total/HDL-cholesterol ratio (p < 0.0001) and mean IMT (p < 0.0001). Atherosclerotic plaques were found in 7 out of 12 subjects (53.8%) with a z-IGF-I score from < or = -2 to -1, in 4 out of 63 (6.3%) with a z-IGF-I score from -0.99 to 0.1 out of 66 (1.5%) with a z-IGF-I score from 0.1 to 1 and none of the 33 subjects with an IGF-I z-score >1 (p = 0.006). At multi-step regression analysis, age was the best predictor of HDL-cholesterol levels and mean IMT, IGF-I level was the best predictor of total cholesterol and total/HDL-cholesterol ratio, the IGF-I/IGFBP-3 molar ratio was the best predictor of triglycerides levels. The z-scores of IGF-I and IGFBP-3 were the second best predictors of mean IMT after age. In conclusion, IGF-I and IGFBP-3 were negatively correlated with common cardiovascular risk factors, studied as total/HDL-cholesterol ratio, and/or early atherosclerosis, studied as IMT at common carotid arteries. The prevalence of atherosclerotic plaques, though not hemodinamically significant, was higher in the subjects having a z-score of IGF-I of < or = -2 to -1. Our results support a role of the IGF/IGFBP-3 axis in the pathogenesis of atherosclerosis.

Abstract
BACKGROUND Patients with acromegaly have an increased morbidity and mortality for cardiovascular diseases. Despite the increasing evidence for the existence of a specific cardiomyopathy in acromegaly, the presence of vascular abnormalities has been never investigated. OBJECTIVE To evaluate the cardiovascular risk and premature atherosclerosis in acromegaly. SUBJECTS Forty-five patients with acromegaly and 30 sex- and age-matched healthy subjects were included in this study: 30 patients were studied at the diagnosis of acromegaly and were in active disease (GH 59.3 +/- 10.2 mU/l, IGF-I 733 +/- 57.6 microg/l) while 15 patients were studied after surgery and/or radiotherapy and were cured from the disease (GH 4.5 +/- 0.7 mU/l, IGF-I 172.4 +/- 16.9 microg/l). METHODS Body mass index (BMI), systolic (SBP) and diastolic blood pressure (DBP), serum total, LDL- and HDL-cholesterol, triglycerides, and fibrinogen levels, prothrombin time (PT), activated partial thromboplastin time (APTT), glucose and insulin levels (fasting and after glucose load) were measured in all patients and controls. By echodoppler ultrasonography, blood systolic (SPV) and diastolic (DPV) peak velocity, and resistance index (RI) were measured at both common and internal carotid arteries where presence, size and location of atherosclerotic plaques were evaluated by B-Mode ultrasonography. Intima-media thickness (IMT) of both common carotids was measured by M-Mode ultrasonography. RESULTS SBP, but not DBP, was significantly higher in patients with active disease than in cured patients and controls (P = 0.003). Hypertension was found in nine (30%) patients with active disease, in two (13.3%) of those cured from acromegaly and in none of controls (chi2 = 10.81, P < 0.004). Fasting blood glucose levels were significantly higher both in patients with active disease and in those cured from the disease than in controls (P < 0.001). Circulating insulin levels were significantly higher in patients with active disease than in cured patients and controls (P < 0.001) and in cured patients than in controls (P < 0.001). Glucose tolerance abnormalities were found in 13 (43.3%) patients with active disease, in four (26.6%) patients with inactive disease and in four controls (13.3%) (chi2 = 6.71, P = 0.03). Total blood cholesterol levels were similar in the three groups, LDL-cholesterol and triglycerides levels were significantly higher, whereas HDL-cholesterol levels were significantly lower both in patients with active disease and in those cured from the disease than in controls (P < 0.001). Serum fibrinogen levels were significantly higher both in patients with active disease and in those cured from the disease than in controls (P < 0.001). No difference was found in PT and APTT levels among the three groups. At the level of right and left common carotid arteries, IMT was significantly higher both in patients with active disease and in those cured from the disease than in controls (P < 0.001). Both right and left SPV, but not DPV, were significantly higher in patients with active disease than in those cured from the disease and in controls (P < 0.01). Well defined carotid wall plaques were detected in two patients (6.6%) with active disease, in one patient cured from the disease (6.6%) and in two controls (6.6%). At the level of right and left internal carotid arteries, SPV, DPV and RI were similar among the three groups. Well defined carotid wall plaques were detected in three patients with active disease (10%), two patients cured from the disease (13.3%) and in one control (3.3%). CONCLUSIONS A significant increase of IMT of both common carotid arteries was observed in patients with active acromegaly, this was also found in those cured from acromegaly. However, the prevalence of well defined carotid plaques was not increased in both groups of patients with acromegaly as compared to controls. On this basis, heart more than vessels seems to be affected by chronic GH and IGF-I excess in acromegaly.

Abstract
The objective of this study was to evaluate the usefulness of a galactose-based ultrasonographic contrast agent, Levovist (Schering AG, Berlin, Germany), in differentiating benign from malignant thyroid nodules by analysis of the time-intensity curves correlating the variation of the intensity signal value during the contrast transit time. Fifty-four patients scheduled for surgical removal of a nodule or the thyroid gland or both after cytologic examination were enrolled in this study; all of the nodules underwent a baseline color and power Doppler evaluation and then to a color Doppler examination after an intravenous bolus injection of Levovist. The time-intensity curves were analyzed with respect to the histologic results. Carcinomas showed a significantly earlier arrival time of Levovist than nodular hyperplastic benign nodules and adenomas (8.1 +/- 1.41 versus 19.6 +/- 2.2 and 16.1 +/- 2.8 seconds; P < .0001), although no significant difference occurred between hyperplastic benign nodules and adenomas; carcinomas and adenomas showed an earlier time to peak than hyperplastic benign nodules (14.6 +/- 1.2 and 23.1 +/- 3.8 versus 33.0 +/- 3.0 seconds; P < .0001). No significant difference was found in baseline, peak, final intensity signal, and percent variation of intensity signal among hyperplastic benign nodules, adenomas, and carcinomas. Although cytologic examination still remains the standard of reference for the presurgical diagnosis of thyroid nodules, the preliminary data of this pilot study demonstrate that the analysis of time-intensity curves after Levovist injection might provide useful, complementary, and quantitative information to differentiate benign from malignant thyroid nodules.

Abstract
The insulin-like growth factors (IGFs) have mitogenic effects on normal and tumoral prostate epithelial cells and have been suggested to be involved in prostate cancer. Moreover, chronic GH and IGF-I excess causes prostate overgrowth in patients with acromegaly. This study was designed to investigate whether the suppression of GH and IGF-I levels by surgery or pharmacotherapy could induce the regression of prostatic hyperplasia in acromegalic patients. To this end, prostate volume (PV) as well as the occurrence of prostatic diseases were studied by transrectal ultrasonography in 23 untreated acromegalic patients (with elevated GH and IGF levels). None of the patients reported symptoms due to prostatic disorders or obstruction. At study entry, prostate hyperplasia was found in half patients. After 2 yr, GH, IGF-I, and IGFBP-3 levels were decreased, whereas prostate-specific antigen levels did not change. PV was decreased in the 16 patients who were well controlled. Among the 6 patients with prostate hyperplasia at study entry who achieved disease control, 4 regained a normal PV at the end of the 2 yr of treatment, whereas none of the 5 patients with prostate hyperplasia at study entry and not achieving disease control normalized their PV. When patients were divided according to age, prostate volume decreased after 2 yr only in the 8 controlled patients aged below 50 yr, but not in those controlled and with age above 50 yr despite similar decrease in GH, IGF-I, and IGFBP3 levels. No clinical, transrectal ultrasonography, or cytological evidence of prostate cancer was detected during the study period. These data suggest that hyperplasia, but not cancer, is frequent in acromegalic men, and that the GH-IGF axis and age are independently associated with the development of this process.

Abstract
BACKGROUND The role of IGF-I in prostate development is currently under thorough investigation since it has been claimed that IGF-I is a positive predictor of prostate cancer. OBJECTIVE To investigate the effect of chronic GH and IGF-I deficiency alone or associated with testosterone deficiency on prostate pathophysiology in a series of patients with hypopituitarism. DESIGN Pituitary, androgen and prostate hormonal assessments and transrectal prostate ultrasonography (TRUS) were performed in 30 men with adulthood onset GH deficiency (GHD) and 30 age-matched healthy controls, free from previous or concomitant prostate disorders. RESULTS Plasma IGF-I levels were significantly lower in GHD patients than in controls (Pearson's coefficient P<0.0001). At study entry, 6 of the 13 hypogonadal patients and 7 of the 17 eugonadal patients had plasma IGF-I below the age-adjusted normal range. At study entry, testosterone levels were low in 13 patients (mean +/-s.e.m., 3.8+/-1.0 nmol/l) while they were normal in the remaining 17 (19.4+/-1.4 nmol/l). No difference in prostate-specific antigen (PSA), and PSA density was found between GHD patients (either hypo- or eugonadal) and controls, while free PSA levels were significantly higher in eugonadal GHD than in controls (0.4+/-0.04 vs 0.2+/-0.03 microg/l; P<0.01). No difference in antero-posterior prostate diameter and transitional zone volume (TZV) was observed among groups, while both transverse and cranio-caudal diameters were significantly lower in hypogonadal (P<0.01) and eugonadal GHD patients (P<0.05) than in controls. Prostate volume (PV) was significantly lower in hypogonadal GHD patients (18.2+/-3.0 ml) and eugonadal GHD patients (22.3+/-1.6 ml), than in controls (25.7+/-1.4, P<0.05). The prevalence of prostate hyperplasia (PV>30 ml) was significantly lower in hypogonadal and eugonadal GHD patients, without any difference between them (15.3% and 5.8%), than in controls (43.3%) (chi(2)=6.90, P=0.005). No difference was found in PV between patients with normal or deficient IGF-I levels both in the hypogonadal group (19. 9+/-4.7 vs 17.3+/-4.0 ml) and in the eugonadal group (22.6+/-2.3 vs 21.8+/-2.5 ml). When controls and patients were divided according to age (<60 years and >60 years), PV was significantly lower in hypogonadal GHD patients aged below 60 years than in age-matched controls (P<0.01) or eugonadal GHD patients (P<0.01), without any difference between controls and eugonadal GHD patients. Controls aged above 60 years had significantly higher PV than both hypogonadal and eugonadal GHD patients (P<0.01). Calcifications, cysts or nodules were found in 56.7% of patients and in 50% of controls (chi(2)=0.067, P=0.79). In controls, but not in GHD patients, PV and TZV were correlated with age (r=0.82, r=0.46, P<0. 0001 and P<0.01 respectively). PV was also correlated with GH (r=-0. 52, P=0.0026), IGF-I (r=-0.62, P=0.0002) and IGF-binding protein 3 (IGFBP-3) levels (r=-0.39, P=0.032) but neither with testosterone or dihydrotestosterone (DHT) levels. In GHD patients TZV but not PV was correlated with age (r=0.58, P=0.0007) and neither TZV nor PV were correlated with GH, IGF-I or IGFBP-3 levels. CONCLUSIONS Chronic GH deficiency in adulthood causes a decrease in prostate size, mostly in patients with concomitant androgen deficiency and age below 60 years, without significant changes in the prevalence of structural prostate abnormalities.

Abstract
The usefulness of a recent color Doppler (CD) ultrasonography technique, named power Doppler (PD), was evaluated in the diagnosis of thyroid nodules showing low or absent uptake of (99m)Tc-pertechnetate, in order to investigate the possibility to improve the diagnostic accuracy of ultrasonography. The rationale was the evidence that at PD the color map displays the total integrated Doppler power in color, while CD generally displays an estimate of the mean Doppler shift. The vascular patterns recorded at PD and CD evaluation of 322 thyroid nodules were compared to the results of cytology and/or histology, when surgery was performed. In respect to the results of cytology, PD has a higher sensitivity (100 vs. 91%) and specificity (95.1 vs. 86.2%) than CD. A similar result was found when PD and CD were compared to the results of histology, sensitivity being 100 vs. 89% and specificity 98.1 vs. 93.7%, respectively. During the follow-up the 2 nodules considered false positive at PD resulted to be tumoral lesions. On this basis, the final specificity of PD in our series was 100%. In conclusion, in the current series including 322 thyroid nodules characterized by a low or absent uptake of (99m)Tc-pertechnetate, PD seems to provide a better characterization of thyroid nodules, possibly allowing a more accurate selection of the patients to subject to fine-needle biopsy.

Abstract
The purpose of this study was to explore the potential role of power Doppler sonography in guiding percutaneous ethanol injection of autonomously functioning thyroid nodules. Thirty-two patients with pretoxic adenoma and 15 with toxic adenoma underwent percutaneous ethanol injection under power Doppler sonographic guidance. All patients with pretoxic adenoma and 13 of 15 patients with toxic adenoma were treated successfully (normalization of circulating thyroid hormones and thyroid stimulating hormone levels and disappearance of nodular hyperactivity with complete recovery of extranodular tracer uptake at scintigraphy). Power Doppler sonography showed the progressive reduction of the intranodular blood flow until its extinction after 6 to 12 months. Nodular shrinkage was obtained in all patients (from 10.85 +/-1.04 to 2.9 +/- 0.3 ml in pretoxic adenoma and from 15.4 +/- 1.8 to 4.2 +/- 0.7 ml in toxic adenoma. Power Doppler sonographic guidance seems to improve the outcome of percutaneous ethanol injection, allowing detection of blood flow even in very small vessels, permitting the ethanol to be guided toward the main afferent vessels of the nodules, and making it possible to monitor the diffusion and the effects of ethanol on nodular vascularization.

Abstract
Hexamethylen-bisacetamide (HMBA) represents the prototype of a group of hybrid polar compounds, which induce differentiation in a variety of transformed cells including human embryonal carcinoma cells. Therefore, HMBA has been used in the differentiation therapy of cancer for patients with both hematological and solid malignancies. Upon HMBA treatment, the embryonal carcinoma cell line NTERA-2 clone D1 (NT2/D1) accumulates in G1 and undergoes terminal differentiation. Here we demonstrate that growth arrest and differentiation of NT2/D1 cells induced by HMBA involve increased expression of the cyclin-dependent kinase inhibitor p27, enhanced association of p27 with cyclin E/CDK2 complexes and suppression of kinase activity associated to cyclin E/CDK2 (but not to cyclin D3/CDK4). When HMBA differentiation was induced in the presence of p27 antisense oligonucleotides, NT2/D1 cells failed to arrest growth properly and, in parallel with the reduction of the anti-apoptotic Bcl-2 gene expression, cells underwent massive programmed cell death. Conversely, constitutive expression of p27 into NT2/D1 cells induced a marked reduction in the growth potential of these cells and partially reproduced HMBA-induced modification of surface antigen expression (down-regulation of SSEA-3 expression and up-regulation of VINIS-53 expression). Expression of p21 induced growth arrest but not differentiation. Likewise, inhibition of CDK2 by transfection of a dominant negative CDK2 in NT2/D1 cells or treatment with the kinase inhibitor olomucine induced growth arrest but not differentiation. Therefore, we propose that p27 represents a crucial molecule in HMBA signaling that cannot be replaced by p21. Furthermore, the results obtained with CDK2 inhibitors demonstrate that the block of CDK2 activity is sufficient for growth arrest but not for cell differentiation and suggest that, at least in these cells, growth arrest and differentiation are regulated by two overlapping but different pathways.

Abstract
Power Doppler (PD) is a recent color-Doppler Ultrasound (US)-technique, which allows to detect the presence of flow even in very small vessels, providing a sort of angiographic micromap. The aim of this study was to evaluate whether percutaneous ethanol injection (PEI) outcome might be improved by injecting the ethanol into the nodule under PD assistance. Thus, 14 patients affected with pretoxic (PTA) and 8 with toxic adenoma (TA) were submitted to this alternative tool. Before PEI, all patients were submitted to a careful endocrinological study, including an US-guided fine-needle biopsy in order to exclude the presence of malignancy. In addition, all the nodules were evaluated at PD-US and their vascular patterns were recorded on videotape and compared with those obtained after treatment. The procedure consisted of slow injection of sterile ethanol under direct PD-US control. The number of PEI sessions was 2.3+/-0.1 in PTA and 3.0+/-0.3 in TA. All patients were also evaluated 3, 6, 12 and 18 months after PEI. Successful therapy was considered when normalization of thyroid hormones and TSH was achieved together with the disappearance of nodular hyperactivity and complete recovery of extra-nodular tracer uptake at scintigraphy. PEI was tolerated very well by all patients. The most common side effect was a transient local or irradiated pain. All patients with PTA and 6 out of 8 patients with TA were successfully treated. In these cases, PD-US showed the progressive reduction of the intranodular blood flow, up to its extinction after 6-12 months, with the presence of little perilesional vascular spots. Nodular shrinkage was obtained in all patients (from 4.7+/-0.7 to 1.1+/-0.4 ml in PTA and from 21.0+/-2.8 to 6.2+/-1.6 ml in TA). In conclusion, PD assistance improves PEI procedure, since it allows to guide the ethanol injection towards the principal afferent vessels of the nodules and to monitor the diffusion and the effects of ethanol on nodular vascularization.

Abstract
The majority of thyroid carcinomas maintain the expression of the cell growth suppressor p27, an inhibitor of cyclin-dependent kinase-2 (Cdk2). However, we find that 80% of p27-expressing tumors show an uncommon cytoplasmic localization of p27 protein, associated with high Cdk2 activity. To reproduce such a situation, a mutant p27 devoid of its COOH-terminal nuclear-localization signal was generated (p27-NLS). p27-NLS accumulates in the cytoplasm and fails to induce growth arrest in 2 different cell lines, indicating that cytoplasm-residing p27 is inactive as a growth inhibitor, presumably because it does not interact with nuclear Cdk2. Overexpression of cyclin D3 may account in part for p27 cytoplasmic localization. In thyroid tumors and cell lines, cyclin D3 expression was associated with cytoplasmic localization of p27. Moreover, expression of cyclin D3 in thyroid carcinoma cells induced cytoplasmic retention of cotransfected p27 and rescued p27-imposed growth arrest. Endogenous p27 also localized prevalently to the cytoplasm in normal thyrocytes engineered to stably overexpress cyclin D3 (PC-D3 cells). In these cells, cyclin D3 induced the formation of cytoplasmic p27-cyclin D3-Cdk complexes, which titrated p27 away from intranuclear complexes that contain cyclins A-E and Cdk2. Our results demonstrate a novel mechanism that may contribute to overcoming the p27 inhibitory threshold in transformed thyroid cells.

Abstract
Patients with Cushing's disease (CD) mainly die because of cardiovascular accidents. The aim of this study was to evaluate whether patients with CD still have increased cardiovascular risk and suffer from premature atherosclerosis once cured. Fifteen patients cured from CD for a long term period (5 yr), 30 sex-and age-matched controls, and 30 body mass index (BMI)-matched controls were included in this study. BMI; waist to hip ratio (WHR); systolic (SBP) and diastolic (DBP) blood pressures; serum total, low density lipoprotein (LDL), and high density lipoprotein (HDL) cholesterol; serum triglycerides, fibrinogen, and lipoprotein(a) levels; prothrombin time; activated partial thromboplastine time; and basal and glucose load-stimulated insulin and glucose levels were measured in patients and controls. By echo-Doppler ultrasonography, the intima media thickness (IMT), systolic and diastolic media-media distances, blood systolic (SPV) and diastolic (DPV) peak velocity, systolic (SLD) and diastolic (DLD) lumen diameter, and distensibility coefficient (DC) were measured at both common carotid arteries where the presence, size, and location of atherosclerotic plaques were also evaluated. Compared with a sex- and age-matched control population, CD patients had BMI (P < 0.001), WHR (P < 0.001), SBP (P < 0.005), DBP (P < 0.05), fasting glucose (P < 0.001) and insulin (P < 0.05), glucose load-stimulated glucose and insulin levels (P < 0.05), total cholesterol (P < 0.05), LDL cholesterol (P < 0.01), fibrinogen (P < 0.01), and lipoprotein(a) (P < 0.05) levels higher and HDL cholesterol levels (P < 0.05) lower than controls. At ultrasonography, in the patients, IMT (P < 0.05), SPV (P < 0.05) and DPV (P < 0.001) were significantly increased whereas SLD (P < 0.001), DLD (P < 0.001), and DC (P < 0.05) were significantly decreased compared to controls. In addition, CD patients had higher WHR (P < 0.05), DBP (P < 0.05), glucose load-stimulated glucose and insulin levels (P < 0.05), and fibrinogen levels (P < 0.01) and lower HDL cholesterol (P < 0.05) levels than BMI-matched controls. At ultrasonography, increased common carotid arteries IMT (P < 0.05) and DPV (P < 0.05) and decreased DLD (P < 0.05) and DC (P < 0.05) were measured in patients compared to those in BMI-matched controls. Atherosclerotic plaques were found in 26.7% of patients, in none of the sex- and age-matched controls, and in 3.3% of the BMI-matched controls. In CD patients, a significant correlation was found between both WHR and fasting serum insulin levels and DBP (r = 0.52 and r = 0.55; P < 0.05), triglycerides levels (r = 0.56 and r = 0.77; P < 0.05), and IMT (r = 0.64 and r = 0.56; P < 0.05). Right (r = -0.70; P < 0.005) and left (r = -0.65; P < 0.01) DC were inversely correlated to the duration of CD in the patient group. At the multiple regression analysis, WHR was the best predictor of fasting insulin levels (beta = 0.77; P < 0.05), and vice versa, fasting insulin level was the best predictor of WHR (beta = 1.20; P < 0.05). In conclusion, patients cured from CD for a long term period have a high prevalence of atherosclerosis and maintain increased several cardiovascular risk factors of the active disease, probably due to a residual abdominal obesity and/or insulin resistance syndrome.

Abstract
The role of insulin-like growth factor I (IGF-I) in prostate development is currently under thorough investigation because it has been claimed that IGF-I is a positive predictor of prostate cancer. To assess the effect of GH and IGF-I levels on prostate pathophysiology, 46 acromegalic (30 in active disease, 10 cured from acromegaly, and 6 affected from GH deficiency) and 30 age-matched male controls, free from previous or concomitant prostate disorders, underwent pituitary, androgen, and prostate hormonal assessments and transrectal ultrasonography. Compared to control values, GH (P < 0.0001), IGF-I (P < 0.0001), and IGFBP-3 (P < 0.001) levels were increased, whereas testosterone (P < 0.0001) and dihydrotestosterone levels (P < 0.0001) were reduced in active acromegalic patients. Hypogonadism was present in 28 of the 46 acromegalic patients (60.8%). The anteroposterior (P < 0.05), and transverse (P < 0.0001) prostate diameters and the transitional zone volume (P < 0.05) were increased in acromegalic patients compared to those in controls. Prostate volume (PV) was significantly higher in untreated acromegalic patients than in controls (41.7 +/- 3.2 vs. 21.9 +/- 1.4 mL; P < 0.0001), cured patients (23.6 +/- 1.6 mL; P < 0.0001), and GH-deficient patients (17.5 +/- 1.1 mL; P < 0.0001). In the patients, PV was correlated with disease duration (r = 0.606; P < 0.0001) and age (r = 0.496; P < 0.0001), whereas in controls it was correlated with age (r = 0.476; P < 0.01) and IGF-I levels (r = -0.448; P < 0.05). Benign prostate hyperplasia (PV > or = 30 mL) was found in 58% of the acromegalics and 26.6% of the controls. When grouped by age (<40, 40-60, and >60 yr), PV was increased in elderly patients compared to younger patients (P < 0.05) and to controls (P < 0.01). The prevalence of structural abnormalities, including calcifications, nodules, cysts, and vesicle inflammation, was significantly increased in patients compared to controls (78.2% vs. 23.3%; chi2 = 5.856; P < 0.05). No clinical, transrectal ultrasonography, or cytological evidence of prostate cancer was detected in acromegalic or control subjects. In conclusion, chronic excess of GH and IGF-I cause prostate overgrowth and further phenomena of rearrangement, but not prostate cancer.

Abstract
This study was designed to investigate whether GH and insulin-like growth factor I (IGF-I) excess could lead to the development of benign prostatic hyperplasia and/or prostatic carcinoma. Prostatic diameters and volume as well as the occurrence of prostatic diseases were studied by ultrasonography in 10 untreated acromegalic patients less than 40 yr of age and 10 age- and body mass index-matched healthy males. Serum GH, IGF-I, PRL, testosterone, dihydrotestosterone, prostate-specific antigen, and prostatic acid phosphatase levels were assessed. All patients had secondary hypogonadism, as diagnosed by low testosterone levels, and 4 of 10 patients had hyperprolactinemia. After 1 yr of treatment with octreotide (0.3-0.6 mg/day), ultrasound scan and hormone parameters were repeated. The 4 hyperprolactinemic acromegalics were treated with octreotide and cabergoline (1-2 mg/week) to suppress PRL levels. Symptoms due to prostatic, seminal vesicle, and/or urethral disorders or obstruction were experienced by neither acromegalics nor controls. Digital rectal examination revealed no occurrence of prostatic nodules or other abnormalities. Compared to healthy subjects, a remarkable increase in transversal prostatic diameter and volume was observed in acromegalics. In healthy subjects, prostate volume ranged from 15.1-21.8 mL, whereas in acromegalics it ranged from 21.8-41.8 mL. Similarly, an increased median lobe was observed. In fact, the transitional zone diameter was just detectable in 5 of 10 controls, whereas it was measurable in all acromegalics (18 +/- 1.2 vs. 2.8 +/- 0.3 mm; P < 0.001). The prevalence of periurethral calcifications was more than doubled in acromegalics (50%) compared to that in controls (20%). Treatment with octreotide for 1 yr produced normalization of circulating GH and IGF-I levels in 7 of 10 patients. In these 7 patients, ultrasound evaluation showed a significant reduction of the antero-posterior diameter (26.1 +/- 1 vs. 28.9 +/- 1.6 mm; P < 0.01), the transversal diameter (44.9 +/- 2 vs. 48 +/- 2 mm; P < 0.01), and the cranio-caudal diameter (36.5 +/- 1 vs. 41.3 +/- 1.5 mm; P < 0.001), whereas the transitional zone diameter was unchanged (16.4 +/- 1.5 vs. 17.4 +/- 1.7 mm). As a consequence, a significant decrease in prostate volume was recorded (22.1 +/- 1.1 vs. 29.8 +/- 2.5 mL; P < 0.001). Prostate volume increased in 2 of the 3 patients who did not achieve normalization of GH and IGF-I after octreotide treatment. Finally, after treatment, serum testosterone levels were significantly increased (from 1.5 +/- 0.3 to 3.5 +/- 0.3 microg/L), whereas dihydrotestosterone, dehydroepiandrosterone sulfate, delta4-androstenedione, 17beta-estradiol, prostate-specific antigen, and prostatic acid phosphatase were unchanged. Serum PRL levels were suppressed after cabergoline treatment in all 4 hyperprolactinemic patients throughout the study period. In conclusion, prostate enlargement occurs in young acromegalics with a higher than expected prevalence of micro- and macrocalcifications. This suggests that a careful prostate screening should be included in the work-up and follow-up of acromegalic males.

Abstract
BACKGROUND AND AIMS The aim of the present study was to compare power Doppler imaging with traditional color Doppler imaging and with contrast enhanced computer tomography in the evaluation of intratumoral vascularity of hepatocellular carcinomas at diagnosis and in response to percutaneous ethanol injection. PATIENTS AND METHODS Sixteen patients with hepatocellular carcinoma underwent colour Doppler, power Doppler and computed tomography at diagnosis. Seventeen patients were studied by the three techniques one month after percutaneous ethanol injection treatment. RESULTS At baseline evaluation, power Doppler and color Doppler were always in agreement and, with the exception of one case, were also in agreement with the computerized tomography scan. On the contrary, power Doppler and computerized tomography are more sensitive than color Doppler in the evaluation of residual vascularized tumoral tissue after percutaneous ethanol injection. In 3 patients, residual vascularity was demonstrated only by computerized tomography while color and power Doppler were negative. In another 3 cases, a positive power Doppler signal, with a typical arterial Doppler spectrum, was observed while color Doppler and computerized tomography were negative. In these patients, cancer relapse was clinically evident after a few months and treatment was repeated to obtain complete necrosis. CONCLUSIONS We conclude that only the integration of the results of all these techniques can reliably evaluate tumoral vascularity after percutaneous ethanol injection.

Abstract
The aim of this study was twofold: first, to improve the predictive value of ultrasonography (US) in differentiating benign from malignant thyroid nodules and, second, to investigate whether color Doppler and power Doppler can distinguish different morpho-hemodynamic patterns of hypoechoic thyroid nodules according to their vascularity. Twenty-nine patients with hypoechoic thyroid nodule(s) were entered into this work in progress. Three typical power Doppler patterns were recorded and compared with color Doppler patterns and with cytologic and/or histologic findings. Power Doppler patterns were classified as follows: type A, a perilesional vascular halo; type B, a peri- and intralesional vascular halo, subdivided into: 1) with moderate intralesional vascularization, homogeneous structure and regular vessel caliber and 2) with rich intralesional vascularization, anarchical structure and winding vessel caliber and flow; type C, a perilesional vascular halo with a characteristic peripheral large afferent vessel characterized by winding caliber and flow. Of 29 patients, 21 had type A power Doppler (benign nodular goiter at cytology, in 4 of them with regressive phenomena); seven patients had type B power Doppler patterns-4 had a subtype 1 pattern (3 with nodular hyperplasias and 1 with a papillary adenoma), 3 had a subtype 2 (two had a follicular adenoma and one had a final diagnosis of angioinvasive follicular carcinoma). The patient with undifferentiated carcinoma had a type C power Doppler pattern. In conclusion, according to our early results, PD seems to be more sensitive and reliable than CD in the screening of thyroid nodules, and to yield better vascular information.
