Abstract
The ion channel two-pore channel 2 (TPC2), localised on the membranes of acidic organelles such as endo-lysosomes and melanosomes, has been shown to play a role in pathologies including cancer, and it is differently expressed in primary versus metastatic melanoma cells. Whether TPC2 plays a pro- or anti-oncogenic role in different tumour conditions is a relevant open question which we have explored in melanoma at different stages of tumour progression. The behaviour of primary melanoma cell line B16F0 and its metastatic subline B16F10 were compared in response to TPC2 modulation by silencing (by small interfering RNA), knock-out (by CRISPR/Cas9) and overexpression (by mCherry-TPC2 transfected plasmid). TPC2 silencing increased cell migration, epithelial-to-mesenchymal transition and autophagy in the metastatic samples, but abated them in the silenced primary ones. Interestingly, while TPC2 inactivation failed to affect markers of proliferation in both samples, it strongly enhanced the migratory behaviour of the metastatic cells, again suggesting that in the more aggressive phenotype TPC2 plays a specific antimetastatic role. In line with this, overexpression of TPC2 in B16F10 cells resulted in phenotype rescue, that is, a decrease in migratory ability, thus collectively resuming traits of the B16F0 primary cell line. Our research shows a novel role of TPC2 in melanoma cells that is intriguingly different in initial versus late stages of cancer progression.

Abstract
PURPOSE The aim of this study was to evaluate the 5-year recurrence rate of pilonidal sinus disease (PSD) after endoscopic sinusectomy and identify risk factors for recurrence. METHODS All consecutive patients from September 2011 through December 2017 who underwent endoscopic sinusectomy at seven referral centres for pilonidal sinus treatment were retrospectively analysed from a prospectively maintained database. RESULTS Out of 290 patients (185 males versus 105 female, with a mean age of 25.5±6.9), 73 presented recurrence at 5-year follow-up with a recurrence rate of 25.2%. The number of pilonidal sinus with pits off the midline (p = 0.001) and the mean (SD) distance from the most lateral orifice to the midline (p = 0.001) were higher in the group of patients with recurrence at 5-year follow-up. Multivariate analysis demonstrated that the position of the pits off the midline (p = 0.001) and the distance of the most lateral orifice from the midline (p = 0.001) were independent risk factors for recurrence at 5-year follow-up. Receiver operating characteristic (ROC) curve analysis showed that the distance of lateral orifice from midline predicted an 82.2% possibility of recurrence at 5-year follow-up and Youden's test identified the best cut-off as 2 cm for this variable. Out of 195 cases with the most lateral orifice less than 2 cm from the midline, 13 presented recurrence at 5-year follow-up with a recurrence rate of 6.7%. Out of 95 cases with the most lateral orifice more than 2 cm from midline, 60 showed recurrence at 5-year follow-up with a recurrence rate of 63.2%. CONCLUSIONS This data may help guide which disease characteristics predict the optimal use of an endoscopic pilonidal sinus technique.

Abstract
Immunohistochemistry for vascular network analysis plays a fundamental role in basic science, translational research and clinical practice. However, identifying vascularization in histological tissue images is time consuming and markedly depends on the operator’s experience. In this study, we present “blood vessel detection—BVD”, an automatic algorithm for quantitative analysis of blood vessels in immunohistochemical images. BVD is based on extraction and analysis of low-level image features and spatial filtering techniques, which do not require a training phase. BVD algorithm performance was comparatively evaluated on histological sections from three different in vivo experiments. Collectively, 173 independent images were analyzed, and the algorithm's results were compared to those obtained by human operators. The developed BVD algorithm proved to be a robust and versatile tool, being able to quantify number, area, and spatial distribution of blood vessels within all three considered histologic datasets. BVD is provided as an open-source application working on different operating systems. BVD is supported by a user-friendly graphical interface designed to facilitate large-scale analysis.

Abstract
Aim: B-cell lymphoma-2 (Bcl-2)-like protein-10 (Bcl2L10) is the less studied
member of Bcl-2 family proteins, with the controversial role in different
cancer histotypes. Very recently, Bcl2L10 expression in melanoma tumor
specimens and its role in melanoma response to therapy have been
demonstrated. Here, the involvement of Bcl2L10 on the in
vitro and in vivo properties associated with
melanoma aggressive features has been investigated. Methods: Endogenous Bcl2L10 protein expression was detected by western blotting
analysis in a panel of patient-derived and commercially available human
melanoma cells. In vitro assays to evaluate clonogenicity,
cell proliferation, cell migration, cell invasion, and in
vitro capillary-like structure formation [vasculogenic
mimicry (VM)] have been performed by using human melanoma cells
stably overexpressing Bcl2L10 or transiently transfected for loss/gain
function of Bcl2L10, grown under two- or three-dimensional (3D) conditions
Xenograft melanoma model was employed to evaluate in vivo
tumor growth and angiogenesis. Results: Results demonstrated that Bcl2L10 acts as an inducer of in
vitro cell migration, invasion, and VM, while in
vitro cell proliferation, in vivo tumor
growth, as well as colony formation properties were not affected. Dissecting
different signaling pathways, it was found that Bcl2L10 positively affects
the phosphorylation of extracellular-signal-regulated kinase (ERK) and the
expression of markers of cell invasion, such as urokinase plasminogen
activator receptor (uPAR) and matrix metalloproteinases (MMPs). Of note,
Bcl2L10-dependent in vitro migration, invasion, and VM are
linked to uPAR. Bcl2L10 also negatively regulates the intracellular calcium
level. Finally, reduced invasion capability in 3D spheroid invasion assay of
melanoma cells transiently overexpressing Bcl2L10 was observed after
treatment with inhibitors of MMPs and uPAR. Conclusions: Overall, data reported in this paper provide evidence supporting a positive
role of Bcl2L10 in melanoma aggressive features.

Abstract
PURPOSE Irisin is a newly discovered adipo-myokine known for having significant effects on body metabolism. Currently, there is a discussion regarding the relation between thyroid function and irisin concentration. This study was designed to evaluate the influential role of levothyroxine replacement therapy on circulating levels of irisin in patients with recently onset hypothyroidism following total thyroidectomy. METHODS Circulating levels of thyroid hormones, irisin and other metabolic parameters, were assessed in 40 recently thyroidectomized patients (34 females, mean age 50.1 ± 15.2 years) at baseline (5-7 day after surgery) and after 2 months under replacement therapy with levothyroxine. RESULTS At baseline, circulating levels of thyroid hormones were indicative of hypothyroidism (TSH 12.7 ± 5.0 μU/mL, FT3 1.9 ± 0.7 pg/mL, FT4 8.7 ± 3.6 pg/mL). Mean serum irisin concentrations significantly increased after 2 months under replacement therapy with levothyroxine (from 2.2 ± 0.6 to 2.9 ± 0.6 μg/mL, p < 0.0001). Variations of circulating levels of irisin under levothyroxine replacement therapy were directly correlated with those of FT3 (Rho = 0.454, p = 0.0033) and FT4 (Rho = 0.451, p = 0.0035). Multivariate regression analysis revealed that changes in thyroid hormones concentrations explained up to 10% of the variations of serum irisin levels under levothyroxine replacement therapy (FT3 R2 = 0.098, FT4 R2 = 0.103). CONCLUSION Our study suggests that levothyroxine replacement therapy mildly influences irisin metabolism in patients with recently onset hypothyroidism following total thyroidectomy.

Abstract
Oleic acid (OA) is a component of the olive oil. Beneficial health effects of olive oil are well-known, such as protection against liver steatosis and against some cancer types. In the present study, we focused on OA effects in hepatocellular carcinoma (HCC), investigating responses to OA treatment (50–300 μM) in HCC cell lines (Hep3B and Huh7.5) and in a healthy liver-derived human cell line (THLE-2). Upon OA administration higher lipid accumulation, perilipin-2 increase, and autophagy reduction were observed in HCC cells as compared to healthy cells. OA in the presence of 10% FBS significantly reduced viability of HCC cell lines at 300 μM through Alamar Blue staining evaluation, and reduced cyclin D1 expression in a dose-dependent manner while it was ineffective on healthy hepatocytes. Furthermore, OA increased cell death by about 30%, inducing apoptosis and necrosis in HCC cells but not in healthy hepatocytes at 300 μM dosage. Moreover, OA induced senescence in Hep3B, reduced P-ERK in both HCC cell lines and significantly inhibited the antiapoptotic proteins c-Flip and Bcl-2 in HCC cells but not in healthy hepatocytes. All these results led us to conclude that different cell death processes occur in these two HCC cell lines upon OA treatment. Furthermore, 300 μM OA significantly reduced the migration and invasion of both HCC cell lines, while it has no effects on healthy cells. Finally, we investigated autophagy role in OA-dependent effects by using the autophagy inducer torin-1. Combined OA/torin-1 treatment reduced lipid accumulation and cell death as compared to single OA treatment. We therefore concluded that OA effects in HCC cells lines are, at least, in part dependent on OA-induced autophagy reduction. In conclusion, we report for the first time an autophagy dependent relevant anti-cancer effect of OA in human hepatocellular carcinoma cell lines.

Abstract
BACKGROUND/AIM Hypoxia-inducible factor 1 (HIF1) inhibitors have been proposed as therapeutic agents for several tumor types. HIF1α is induced by hypoxia and by pathogens in normoxia through toll-like receptors (TLRs). The TLR3 activator polyinosinic:polycytidylic acid [poly(I:C)] induces apoptosis in various types of cancer but not in the most aggressive breast cancer cell lines. We hypothesized that the failure of TLR3 stimulation to induce apoptosis in these cells might be due to an elevated HIF1α level and this link might be exploited. MATERIALS AND METHODS Poly(I:C)-induced signaling pathway and expression of HIF1α and HIF1α targets were studied in MDA MB-231 and MCF-7 breast cancer cell lines by western blot. Flow cytometry was used for apoptotic responses and vasculogenic mimicry as bioassay. RESULTS Poly(I:C) increased expression of HIF1α and its targets BCL2 apoptosis regulator and c-MYC. Moreover, using pharmacological or genetic HIF1 inhibition, reduction of poly(I:C)-induced expression of HIF1α was paralleled by lowering of c-MYC and increased sensitivity to poly(I:C)-induced apoptosis, demonstrating the crucial role of this factor. We provide the first evidence in breast cancer cells that TLR3 stimulation induces HIF1α-dependent vasculogenic mimicry. By using specific inhibitors, we identified a signaling cascade upstream of HIF1α induction. CONCLUSION Combined treatment with poly(I:C) and HIF1 inhibitors deserves consideration as an effective strategy in breast cancer therapy.

Abstract
Endothelial cells (ECs) constitute the innermost layer that lines all blood vessels from the larger arteries and veins to the smallest capillaries, including the lymphatic vessels. Despite the histological classification of endothelium of a simple epithelium and its homogeneous morphological appearance throughout the vascular system, ECs, instead, are extremely heterogeneous both structurally and functionally. The different arrangement of cell junctions between ECs and the local organization of the basal membrane generate different type of endothelium with different permeability features and functions. Continuous, fenestrated and discontinuous endothelia are distributed based on the specific function carried out by the organs. It is thought that a large number ECs functions and their responses to extracellular cues depend on changes in intracellular concentrations of calcium ion ([Ca2+]i). The extremely complex calcium machinery includes plasma membrane bound channels as well as intracellular receptors distributed in distinct cytosolic compartments that act jointly to maintain a physiological [Ca2+]i, which is crucial for triggering many cellular mechanisms. Here, we first survey the overall notions related to intracellular Ca2+ mobilization and later highlight the involvement of this second messenger in crucial ECs functions with the aim at stimulating further investigation that link Ca2+ mobilization to ECs in health and disease.

Abstract
BACKGROUND AND AIM Subclinical hypothyroidism has been linked to increased risk of atherosclerotic disease. Soluble CD40 ligand (sCD40L), mainly derived from activated platelets, and the lipid peroxidation product 8-iso-prostaglandin F2α (8-iso-PGF2α) are known to play a relevant pathophysiological role in atherogenesis. In this study, we analyzed the relationship between thyroid hormones and circulating levels of sCD40L and 8-iso-PGF2α in patient with recent-onset post-thyroidectomy subclinical hypothyroidism under replacement therapy. METHODS AND RESULTS Circulating levels of thyroid hormones, sCD40L, and 8-iso-PGF2α were assessed in 40 recently thyroidectomized patients (33 females, mean age 52.0 ± 11.7 years) at baseline (5-7 day after surgery) and after 2 months under replacement therapy with levothyroxine (LT-4). At baseline, circulating levels of thyroid hormones were indicative of a subclinical hypothyroidism (TSH 7.7 ± 3.9 μU/mL, FT3 1.8 ± 0.6 pg/mL, and FT3 8.9 ± 3.0 pg/mL). Circulating levels of sCD40L and 8-iso-PGF2α were directly correlated with each other (r = 0.360, p = 0.023) and with TSH levels (r = 0.322, p = 0.043 and r = 0.329 p = 0.038, respectively). After 2 months under the replacement therapy with LT-4 circulating levels of TSH (from 7.7 ± 3.9 to 2.7 ± 2.8 μU/mL, p < 0.0001), sCD40L (from 6.11 ± 2.41 to 2.43 ± 2.00 ng/mL, p < 0.0001) and 8-iso-PGF2α (from 45.33 ± 6.94 to 40.36 ± 6.20, p < 0.0001) significantly decreased. Changes in circulating levels of sCD40L and 8-iso-PGF2α were directly correlated with each other (r = 0.349 p = 0.028) and with changes in TSH levels (r = 0.367 p = 0.020 and r = 0.339 p = 0.032, respectively). CONCLUSION Our study suggests an influential role of TSH on proatherogenic activation of platelets, probably through enhanced lipid peroxidation. These findings could partially explain the increased susceptibility of patients with subclinical hypothyroidism to develop atherosclerotic disease.

Abstract
PURPOSE Inhibition of AKT is a key target area for personalized cancer medicine. However, predictive markers of response to AKT inhibitors are lacking. Correspondingly, the AKT-dependent chain of command for tumor growth, which will mediate AKT-dependent therapeutic responses, remains unclear. EXPERIMENTAL DESIGN Proteomic profiling was utilized to identify nodal hubs of the Trop-2 cancer growth-driving network. Kinase-specific inhibitors were used to dissect Trop-2-dependent from Trop-2-independent pathways. In vitro assays, in vivo preclinical models, and case series of primary human breast cancers were utilized to define the mechanisms of Trop-2-driven growth and the mode of action of Trop-2-predicted AKT inhibitors. RESULTS Trop-2 and AKT expression was shown to be tightly coordinated in human breast cancers, with virtual overlap with AKT activation profiles at T308 and S473, consistent with functional interaction in vivo AKT allosteric inhibitors were shown to only block the growth of Trop-2-expressing tumor cells, both in vitro and in preclinical models, being ineffective on Trop-2-null cells. Consistently, AKT-targeted siRNA only impacted on Trop-2-expressing cells. Lentiviral downregulation of endogenous Trop-2 abolished tumor response to AKT blockade, indicating Trop-2 as a mandatory activator of AKT. CONCLUSIONS Our findings indicate that the expression of Trop-2 is a stringent predictor of tumor response to AKT inhibitors. They also support the identification of target-activatory pathways, as efficient predictors of response in precision cancer therapy. Clin Cancer Res; 22(16); 4197-205. ©2016 AACR.

Abstract
Erythropoiesis is affected during deep saturation dives. The mechanism should be related to a downregulation of serum Erythropoietin (s-EPO) concentration or to a toxic effect of the hyperbaric hyperoxia. We evaluated s-EPO and other haematological parameters in 6 scuba divers before, during and after a 14-days guinness saturation dive (8-10 m). Athletes were breathing air at 1.8-2 ATA, under the control of a team of physicians. Serum parameters were measured before diving (T0) and: 7 days (T1), 14 days (T2) after the beginning of the dive and 2 h (T3) and 24 h (T4) after resurfacing. Hgb, and many other haematological parameters did not change whereas Ht, s-EPO, the ratio between s-EPO predicted and that observed and reticulocytes (absolute, percent) declined progressively from T0 to T3. At T4 a significant rise in s-EPO was observed. Hgb did not vary but erythropoiesis seemed to be affected as s-EPO and reticulocyte counts showed. All these changes were statistically significant. The experiment, conducted in realistic conditions of dive length, oxygen concentration and pressure, allows us to formulate some hypotheses about the role of prolonged hyperbarism on erythropoiesis. The s-EPO rise, 24 h after resurfacing, is clearly documented and related to the "Normobaric Oxygen Paradox". This evidence suggests interesting hypotheses for new clinical applications such as modulation of s-EPO production and Hgb content triggered by appropriate O₂ administration in pre-surgical patients or in some anemic disease.

Abstract
Hemifacial spasm (HFS) is a facial movement disorder characterized by involuntary, unilateral and intermittent contractions of the facial muscles. It is one of the syndromes related to neurovascular conflict, first described by Jannetta et al. in 1979. Typically, HFS is due to pulsatile compression by the anterior inferior cerebellar artery. We describe a rare case of left developmental venous anomaly in a 59-year-old man referred to us with a six-month history of left-sided HFS. We performed an MR study of the brain and cerebellopontine angles, which demonstrated a compression of the ipsilateral facial nerve by the developmental venous anomaly.

Abstract
Blunt head trauma without any temporal bone fracture or longitudinal temporal bone fracture, with an associated fracture of the labyrinth may cause labyrinthine injury with sensor neural hearing loss and vertigo because of a concussive injury to the membranous labyrinth. Sudden sensory neural hearing loss is relatively frequent. In most cases, the etiology is not discovered. One of the possible causes for sudden deafness is inner labyrinth bleeding or concussion, which were difficult to diagnose before the advent of magnetic resonance imaging. Vertigo without a demonstrable fracture may also be the result of labyrinthine concussion, cupololithiasis and perilymphatic fistula. We describe the clinical case of a patient with acute traumatic hearing loss and vertigo, without skull base fracture detected on computed tomography. Magnetic resonance study was also performed. We have integrated the discussion with features that allow the differential diagnosis from other similar conditions.

Abstract
We describe a case of Septo-Optic Dysplasia (SOD) characterized by the presence of anomalous cerebral vessels. In our young patient the classical features of SOD were associated with vascular anomalies including absence of the vein of Galen, right Rosenthal vein leading to the superior petrosal sinus, and anomalous origin of the anterior choroidal arteries. These findings have never been associated with SOD in the literature but their revelation supports the hypothesis of a vascular disruption as a possible cause of the SOD.

Abstract
Guillain-Barré syndrome is a post infectious, immune-mediated disease with cranial nerve involvement observed in 45–75% of patients. Bilateral facial nerve palsy is rather uncommon and occurs in 0.3% to 2% of all facial palsies. We describe a rare case of a 29-year-old man with bilateral facial palsy caused by a Guillain-Barré syndrome with an unusual onset and progression of neurological symptoms. Neuroradiological findings in our patient are described and compared with data from literature on bilateral facial palsies to make differential diagnosis easier for neuroradiologists.

Abstract
We describe a case of an occult spinal neurenteric cyst associated with congenital hemivertebrae. Different intraspinal anomalies, such as neurenteric cysts (representing 0.3 to 0.5 % of all spinal tumors) have been reported in association with congenital hemivertebrae. Indeed, although CT is the best examination to study vertebral anomalies, MRI should be performed in order to exclude a more complex dysraphic condition.

Abstract
We describe a case of endovascular management of a ruptured aneurysm of the intracavernous portion of the left internal carotid artery with sphenoid extension. The exclusive use of coils to embolize the aneurysm in acute and young patients offers the advantage of avoiding both pre-implant antiplatelet therapy and long-term anticoagulant therapy required after stent or vascular plug placement, but it is complicated by the non-negligible risk of recurrence. Indeed, the only secure method to treat ruptured aneurysms of the intracavernous portion of the internal carotid artery is to use coils in the first stage to stop the haemorrhage without antiplatelet therapy and to use stents in the second narrow stage to prevent revascularization.

Abstract
Scuba diving is known to affect the rhino-pharyngo-tubaric district (RPT unit). The aim of the study was to document function modifications of the RPT unit in 6 Italian divers (3 men and 3 women) who lived for 14 days consecutively at a depth of 8-10 m, breathing air (21% oxygen) at a pressure ranging between 1.8 and 2 ATA. RPT and inner ear assessment were carried out before the dive (TIME 0) and 24 h (TIME 1) after resurfacing, in order to investigate diving-related RPT and inner ear alterations. Physical examination after resurfacing revealed: fungal external otitis, otoscopic findings consistent with middle ear barotraumas and rhinosinusitis. Rhino-manometry showed a remarkable increase in inspiratory nasal flow and a substantial decrease in nasal resistance. No epithelial cell disruption was retrieved comparing pre and post resurfacing samples. Post-diving tubaric dysfunction was found. Pure tone audiometry revealed a bilateral 40 dB HL hearing loss at 4 kHz in 1 diver. Relevant PTA functions did not seem to be affected by the experiment, no remarkable changes were found at the Sensory Organisation Test and at the Motor Control Test. The 14-day underwater period had a positive effect on nasal flows and resistances.

Abstract
We describe the imaging findings of a man who developed neurologic symptoms due to ossification of the posterior longitudinal ligament with narrowing of the spinal canal and compression of the spinal cord. CT study allowed a detailed evaluation of the stenosis and the extension of the ossification while MRI gave an excellent visualization of the spinal lesions caused by spinal cord compression by the mass. The neurological status of patients with ossification of the posterior longitudinal ligament depends on many factors such as the degree of spinal canal stenosis, life style, accidental mechanical stress and trauma.

Abstract
AIM To determine the prevalence and nature of disability at 2 years of age in infants born from 1993 to 2002 with a birth weight of <1500 g. METHODS A prospective cohort analysis of all eight neonatal units in East Anglia, UK using a single database. Local paediatricians assessed children at 2 years of age using the Health Status Questionnaire. Data were analysed using SPSS v 9 and MSAccess 97. RESULTS 97% of the 1850 survivors were assessed at 2 years. 21% had mild disability, 10.8% moderate and 8.6% severe. There was no evidence of an increased rate of disability despite survival rates increasing from 75% in 1993 to 89% in 2002. There was an increased trend in survival of infants of <28 weeks' gestation from 17% to 21% (p=0.08), and the overall rate of moderate to severe disability decreased significantly from 35% to 28% (p<0.01). There was a decreasing trend in the number of infants with cerebral palsy (6% vs 4%). There was also a decrease in the numbers of infants with blindness, hydrocephalus or a hearing impairment. Follow-up rates decreased from 99% to 94.5%. Analysis of those lost to follow-up revealed they were of higher gestation and birth weight. CONCLUSION There was no evidence of an increased rate of disability despite improved survival rates over the two time periods. The rate of blindness decreased, probably reflecting earlier treatment of retinopathy of prematurity. This study demonstrates that although follow-up remains a challenge, rates of over 90% are achievable.

Abstract
Klumpke's palsy is a rare form of paralysis involving the muscles of the forearm and hand, resulting from a brachial plexus injury in which the eighth cervical (C8) and first thoracic (Th1) nerves are injured either before or after they have joined to form the lower trunk. We report a case of a 45 years-old woman with post-traumatic left cervical-brachial pain afflicted by obstetric brachial plexus palsy on the right side. Magnetic Resonance Imaging (MRI) examination of the cervical spine revealed a meningeal stretch in the left side at C7-Th1 level, responsible for pain, and also multiple intraforaminal pseudomeningoceles at C5-C6, C6-C7 and C7-Th1 intersomatic spaces in the right side, due to the perinatal trauma that had determined the obstetric brachial plexus palsy. Spinal pseudomeningocele is an extradural collection of CSF in the surrounding soft tissues due to a dural breach and can represent a predictive finding of injury of the brachial plexus. We obtained clinical and electrophysiological findings of Klumpke's palsy, but MRI examination showed the lack of visualization of C8 and the integrity of Th1 nerve roots and to our knowledge there is no evidence in literature about the possibility to have a partial Klumpke's palsy without Th1 avulsion. The aim of this article was to underline that for the correct assessment of patients with brachial plexus palsy the only use of MRI is insufficient: it is necessary an integration of the information obtained from clinical, electromyographic and MRI study.

Abstract
In selected patients, video-assisted thyroidectomy can be considered a safe and validated procedure offering significant advantages over conventional surgery, with no additional morbidity. Aim of this study was to evaluate the results obtained in a series of patients selected for video-assisted thyroidectomy over a 10-years period. All patients who underwent video-assisted thyroidectomy from June 1998 to June 2009 were considered. The eligibility criteria for video-assisted thyroidectomy are: thyroid nodules < or = 35 mm; estimated thyroid volume < 30 ml; no previous conventional neck surgery and/or radiation therapy; small, low-risk papillary thyroid carcinoma. A total of 1363 video-assisted thyroidectomies were attempted in the time period considered. Conversion to the conventional procedure was necessary in 7 cases. Thyroid lobectomy was successfully performed in 157 cases, total thyroidectomy in 1175, and completion thyroidectomy in 24. In 126 patients, the central neck nodes were removed through the same access. Simultaneous video-assisted parathyroidectomy, for a parathyroid adenoma, was performed in 42 patients. Pathological studies showed benign disease in 986 cases, papillary thyroid carcinoma in 368 cases, C-cells hyperplasia in 1 case, and medullary microcarcinoma in 1 patients with RET germline mutation. Post-operative complications included 27 transient and 1 definitive recurrent laryngeal nerve palsy, 230 transient hypocalcemia, 10 definitive hypoparathyroidism, 4 postoperative hematoma and 5 wound infection.

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

Abstract
Variants of the opioid receptors are the obvious candidates underlying addiction. The kappa opioid receptor (KOR) system seems to play a role in stress responsivity, opiate withdrawal and responses to psycho-stimulants, inhibiting mesolimbic dopamine. KOR gene polymorphisms have been reported to contribute to predisposition to voluntary alcohol-drinking behavior in experimental animals. In humans, the 36G > T single nucleotide polymorphism (SNP) on KOR gene, that was recently identified, has been found associate with substance dependence, with inconclusive findings. In the present study, 106 heroin addicts (West European, Caucasians) and 70 healthy control subjects matched for race and gender, with no history of substance use disorder, have been genotyped. The frequency of KOR 36G > T SNP was significantly higher among heroin-dependent individuals compared with control subjects (Fisher's exact = 0.044; Pearson chi(2) = 4.2734, P = 0.039; likelihood ratio chi(2) tests = 4.6156, P = 0.032). Although KOR silent polymorphisms may apparently have no consequences on mRNA transcription, post-transcriptional mechanisms, such as mRNA stability, translation efficiency, and regulability may impair the function of kappa receptors system, with increased risk for substance use disorders. In specific, the neurobiological changes induced by mu-kappa opioid imbalance could underlie vulnerable personality traits and risk behavior.

Abstract
This study was designed to evaluate physiological and psychological stress parameters in 2 professional trained scuba divers, using a unique physiopathologic model, offered by the guinness 240 hours scuba dive. Two scuba dive masters have spent 240 hours at 6 - 8 meters depth (26.4 ft) in Ponza Island water (Italy). Blood samples were collected daily in the underwater bell; samples were carried out of water in waterproof bags. Breath samples were collected, measuring ethylene release. Psychological assessment was performed using the State and Trait Anxiety Inventory and the Zung self-rating depression scale. In the studied subjects, cortisol and prolactin showed physiological pulsatile secretion. Breath ethylene didn't exceed normal values. At the start of the study, no subjects showed high levels of state anxiety, trait anxiety and current depression. Psychometric scales scores remained steady during the diving period and no subjects showed anxiety and/or depression and/or panic symptoms during the time of observation. The present study shows that, although the long-time diving, well trained professional divers did not develop anxiety and/or depression. No subject discontinued the diving due to occurred psychological disorders or systemic events. The present report shows that the long-term diving permanence is possible, at least in well trained scuba divers.

Abstract
AIM To determine the type and rate of disability at 2 years of age in infants born in the geographically defined population of East Anglia with a birthweight less than 1500 g and to assess the risk factors for disability. STUDY DESIGN A prospective cohort analysis from all eight neonatal units in East Anglia from 1993-1997 using a single database. METHODS Local paediatricians assessed children at 2 years using the Health Status Questionnaire and data collection was centrally coordinated. RESULTS Outcomes for 947 children, 99% of survivors, were available, 74 (7.8%) had severe disability and this was significantly associated with gestational age (p<0.0005), birthweight (p<0.0005) and sex (p=0.046). Major congenital abnormality contributed 27% of all severe disability. The overall cerebral palsy rate was 6.2%, nine children were blind and five had sensorineural hearing loss requiring aids. These children had a high level of use of community services with 19% of the cohort being referred to one or more community service. ELBW infants or those born <30 weeks gestation were 1.5 times and twice as likely to have moderate or severe disability and 2.3 and 5.4 times as likely to have cerebral palsy as those weighing 1000 to 1500 g or >30 weeks gestation. Boys were at higher risk of adverse outcome. CONCLUSIONS The study was able to define the increased risk associated with being born at lower gestational age or lower birthweight and demonstrates successful ascertainment of outcomes for large local populations at a reasonable cost.

Abstract
AIMS 1. To determine the survival and morbidity of infants at discharge with a birthweight of less than 1500 g in the geographically defined population of East Anglia. 2. To demonstrate a cost-effective method of regional data collection. 3. To determine whether there were any changes in the demand for neonatal care. STUDY DESIGN AND SUBJECTS A prospective cohort analysis using a single database to collect data on 1244 very low birthweight infants from eight neonatal units in one Region from 1993 to 1997. RESULTS Estimated ascertainment of VLBW infants to the study was 96%. Over the 5 years survival rates were stable (75-79%). 52% of deaths in infants admitted for neonatal care occurred on day 1, with just 15% of deaths occurring after 28 days of life. Mortality risk significantly decreased with increasing gestational age at birth. Compared to 22-25-week old infants, the mortality risk decreased by 65% for 26-27-week old infants (OR 0.35 95% CI (0.21, 0.59)) and by 92% for 32-39-week old infants (OR 0.08 95% CI (0.03, 0.21)) with intermediate odds ratios of 0.22 (0.12, 0.42) and 0.13 (0.06, 0.28) for the 28-29 and 30-39 weeks gestation, respectively. Higher birthweight, after adjusting for gestation also decreased the mortality risk (OR 0.78 per 100 g difference, 95% CI (0.71, 0.86)). No change was seen in the number of extremely preterm infants admitted for intensive care or resource utilisation, although a significant increase was seen in the number of infants dying in delivery rooms. There was a reduction in the reported incidence of pulmonary interstitial emphysema (10-4%) but no change in the number of ventilation days or the rate of chronic lung disease. The mean maternal age increased from 27.7 years to 28.9 years during the study. Maternal steroid administration increased (30% to 59%) and was associated with a decreased risk of mortality (OR 0.44, 95% CI: 0.31-0.62). CONCLUSIONS It is possible to collect useful data from the neonatal period at a reasonable cost from a geographically defined population. This information was used for informing clinicians, counselling parents and in the era of managed clinical networks will be useful in guiding the provision of effective health care resources.

Abstract
OBJECTIVE To obtain data on correlates of climacteric symptoms in women around menopause attending menopause clinics in Italy. METHODS Since 1997 a large cross sectional study has been conducted on the characteristics of women around menopause attending a network of first level menopause outpatient's clinics in Italy. A total of 66,501 (mean age 54.4 years) women are considered in the present paper. RESULTS The odds ratios of moderate and severe hot flashes/night sweats were lower in more educated women and (for severe symptoms only) in women reporting regular physical activity. Depression, difficulty to sleep, forgetfulness and irritability tended to be less frequent in more educated women and (depression only) in women reporting regular physical activity. Parous women reported more frequently these symptoms. CONCLUSIONS This large study confirms in Southern European population that low education, body mass index and low physical activity are associated with climacteric symptoms. Parous women are at greater risk of psychological symptoms.

Abstract
Differentiated thyroid carcinoma (DTC) is rare in young patients and represents 0,5 to 3,0% of childhood carcinomas. The incidence increases with age: a peak incidence is observed between 15 and 19 years of age. DTC in children is frequently associated with greater risk of cervical lymph node involvement (60-80% of cases) and lung metastases at diagnosis in 20% of patients. However the prognosis for these patients is better when compared with that of adults, despite a high incidence of relapse, leading to reoperation. Young age (<16 years), lymph node involvement or distant metastases at diagnosis and some histopathologic characteristics have been suggested as predictive factors of recurrences. The records of 33 patients with DTC in a 14-year period (1990-2004) were reviewed. There were 31 females and 2 males who ranged from 11 to 21 years. At the diagnosis 15 patients had disease confined to the thyroid, 18 had additional lymph node metastases in the neck; one of them had also lung metastases. Total thyroidectomy (TT) was the elective approach in all patients (4 cases videoassisted). TT was associated to functional neck dissection in 21 cases. 131I was administrated to 28 patients (3,7 GBq as ablative dose): 11 of this received further radioiodine treatments (mean 7,4 GBq) because of elevated serum thyroglobulin levels and presence of loco-regional or lung metastasis at diagnostic total body scan after 131I treatment. The overall survival rate was 100% at a follow up of 4 months to 14 years.

Abstract
A case of non-accidental injury to an infant caused by the discharge of an air pistol is presented, the first such case to be reported. A two-month-old baby was shot at close range by his father with a .177 air pistol. A false account of the cause of the injury was given by the father and initially supported by the mother. The pellet penetrated the skin in the centre of the child's forehead and lodged in the anterior wall of the sagittal sinus. It was removed under general anaesthetic and the child made an uncomplicated recovery. The father was subsequently convicted and jailed for the assault. The relevant literature on air weapon injuries and bizarre forms of child abuse is discussed.

Abstract
Advancing age has been found to be associated with a decline in insulin action. Nevertheless, no study has been conducted in healthy centenarians. Our study investigates glucose tolerance and insulin action in centenarians. Fifty-two subjects were enrolled. The subjects were divided in three groups as follows: 1) adults (< 50 yr; n = 20);2) aged subjects (> 75 yr; n = 22); and 3) centenarians (> 100 yr; n = 14). Body composition was studied by bioimpedance analysis. In all subjects, an oral glucose tolerance test and euglycemic glucose clamp were performed. Centenarians have a lower fat-free mass (FFM) than aged subjects and adults, whereas fasting plasma glucose, triglycerides, free fatty acids, urea, and creatinine were not different in the groups studies. Centenarians had a 2-h plasma glucose concentration (6.0 +/- 0.2 mmol/l) that was lower than that in aged subjects (6.6 +/- 0.5 mmol/l, P < 0.05) but not different from adults [6.4 +/- 0.4 mmol/l, P = not significant (NS)]. During the clamp, plasma glucose and insulin concentrations were similar in the three groups. In these conditions, centenarians had a whole body glucose disposal (34.1 +/- 0.6 mumol.kg FFM-1.min 1) that was greater than that in aged subjects (23.3 +/- 0.5 mumol.kg FFM-1.min-1 P < 0.01) but not different from adults (34.6 +/- 0.5 mumol/kg x min, P = NS). In conclusion, our study demonstrates that centenarians compared with aged subjects had a preserved glucose tolerance and insulin action.

Abstract
Our study investigates short- and long-term effects of infusion of non-esterified fatty acids (NEFA) on insulin secretion in healthy subjects. Twelve healthy individuals underwent a 24-h Intralipid (10% triglyceride emulsion) infusion at a rate of 0.4 ml/min with a simultaneous infusion of heparin (a bolus of 200 U followed by 0.2 U/min per kg body weight). After an overnight fast (baseline), at 6 and at 24 h of Intralipid infusion and 24 h after Intralipid discontinuation (recovery test), all subjects underwent an intravenous glucose tolerance test (iv-GTT) (25 g of glucose/min). Intralipid infusion caused a threefold rise in plasma NEFA concentrations with no difference between the 6- and the 24-h concentrations. Compared to baseline acute insulin response (AIR) (AIR = 63 +/- 8 mU/l), short-term (6-h) Intralipid infusion was associated with a significant increase in AIR (86 +/- 12 mU/l p < 0.01); in contrast, long-term (24-h) Intralipid delivery was associated with inhibition of AIR (31 +/- 5 mU/l) compared to baseline (p < 0.001) and to the 6-h (p < 0.03) triglyceride emulsion infusion. Intralipid infusion was associated with a progressive and significant decline in respiratory quotient (RQ). A positive correlation between changes in fasting plasma NEFA concentrations and AIR at the 6-h infusion (r = 0.89 p < 0.001) was found. In contrast, at the end of the Intralipid infusion period, changes in plasma NEFA concentrations and AIR were negatively correlated (r = -0.87 p < 0.001). The recovery test showed that fasting plasma NEFA concentrations, RQ and AIR had returned to baseline values. In the control study (n = 8) 0.9% NaCl infusion did not mimick the effect of Intralipid. In conclusion, our study demonstrates that short- and long-term exposures of beta cells to high plasma NEFA concentrations have opposite effects on glucose-induced insulin secretion.

Abstract
Our study investigated body composition and body fat distribution in healthy centenarians. Body composition, body fat distribution, and resting metabolic rate (RMR) were studied in 40 adult subjects aged < 50 y, 35 aged subjects > 75 y, and 15 healthy centenarians aged > 100 y. Body composition was determined by bioimpedance analysis, body fat distribution was calculated as waist-hip ratio (WHR), and RMR was calculated by using the Arciero-Poehlman formula. Healthy centenarians had a cognitive impairment and degree of disability greater than aged subjects. Despite such differences, fat-free mass (FFM) and RMR were not different in centenarians compared with aged subjects but were lower than in adult subjects. In contrast, healthy centenarians had a WHR lower than that of aged subjects but not different from that of the adult subjects. After the level of physical activity and degree of disability were adjusted for, FFM (44 +/- 2.7 and 40 +/- 1.1 kg; P < 0.05) and RMR (6757 +/- 761 and 5891 +/- 723 kJ/24 h; P < 0.05) were significantly higher in healthy centenarians than in aged subjects, respectively. Independent of age, sex, body weight, degree of disability, level of physical activity, and fasting plasma triiodothyronine, there was a strong correlation between RMR and FFM (r = 0.50, P < 0.05) in healthy centenarians. In conclusion, healthy centenarians had a lower FFM and higher body fat content than aged subjects. Level of physical activity and degree of disability seem to be the major determinants for explaining such differences.

Abstract
Fourteen hypertensive (174.3/98.3 mmHg) non-diabetic patients were given a euglyceamic glucose clamp along with infusion of 0.9% NaCl and the prostacyclin (PGI2) analogue Iloprost (0.7 ng x kg x min(-1)). Substrate oxidation was also determined by indirect calorimetry. Over the last 60 min of the clamp, Iloprost vs saline improved whole body glucose disposal (WBGD) (35 vs 28.3 micromol x kg(-1) LBM) and non-oxidative glucose metabolism (24.7 vs 18.1 micromol x kg(-1) LBM x min(-1). Iloprost delivery was associated with a significant decrease in membrane microviscosity (0.253 vs 0.205), but did not affect arterial blood pressure and heart rate. In nine patients, skeletal muscle blood flow (SMBF) and insulin-stimulated glucose uptake (GU) were also studied. At the end of the study, despite a similar SMBF (37 vs 38 ml x min(-1) x kg(-1)), GU (0.55 vs 0.46 mmol x l(-1)) was significantly increased by Iloprost infusion. Percentage decrease in membrane microviscosity was correlated with percentage increase in WBGD (r = 0.65) and non-oxidative glucose metabolism (r = 0.68). In conclusion, low-dose Iloprost infusion improves insulin action and non-oxidative glucose metabolism in hypertensive patients.

Abstract
Hypertensive patients with left ventricular hypertrophy (LVH) have a higher degree of hyperinsulinaemia than hypertensive patients without LVH. Obese patients with LVH have also been demonstrated to have a very low glucose disappearance rate after an intravenous glucose bolus. No studies have investigated the difference in insulin action and substrate oxidation in hypertensive patients with and without LVH. For this reason 36 subjects were enrolled for our study: (1) healthy control subjects (n = 10); (2) hypertensive patients without LVH (n = 12); and (3) hypertensive patients with LVH (n = 14). All subjects underwent an oral glucose tolerance test (OGTT, 75 g of glucose) and a euglycaemic hyperinsulinaemic glucose clamp (insulin infusion rate, 7.1 pmol (kg min)-1 for 120 min). In this latter test indirect calorimetry allowed substrate oxidation determination. Echocardiographic methods allowed LVH assessment. Hypertensive patients with LVH had the lowest insulin-mediated nonoxidative glucose metabolism compared to hypertensive patients without LVH (P < 0.01) and to healthy subjects (P < 0.001). In the whole group of hypertensive patients (n = 26), partial correlations showed left ventricular mass index (LVMI) associated with fasting plasma insulin levels (r = 0.44 P < 0.005), insulin-mediated whole body glucose disposal (r = -0.41 P < 0.01) and nonoxidative glucose metabolism (r = -0.33 P < 0.04) independently of age, body weight, systolic blood pressure and plasma catecholamines levels. In conclusion, our data provide evidence that LVH in hypertensive patients is associated with a worsening in nonoxidative glucose metabolism.

Abstract
OBJECTIVE To investigate the effect of iloprost infusion on insulin action. RESEARCH DESIGN AND METHODS Thirteen healthy subjects and 13 non-insulin-dependent diabetes mellitus (NIDDM) patients matched for age (68.2 +/- 0.5 vs. 67.9 +/- 0.5 years, NS), gender ratio (7 men:6 women vs. 6 men:7 women), body weight, body fat distribution, arterial blood pressure, and plasma triglyceride levels (1.89 +/- 0.09 vs. 1.87 +/- 0.08 mmol/l, NS) were studied. In eight healthy subjects and eight NIDDM patients, we studied insulin action by euglycemic glucose clamp (insulin infusion rate 2 mU.kg-1.min-1) along with saline and iloprost delivery (0.7 ng.kg-1.min-1). In the other five subjects of each group, forearm blood flow and insulin-mediated glucose uptake during saline and iloprost infusion (0.7 ng.kg-1.min-1) were investigated. RESULTS Iloprost infusion improved insulin-stimulated whole-body glucose uptake and oxidative and nonoxidative glucose metabolism in both study groups. Forearm blood flow under basal conditions and with insulin infusion (2 mU.kg-1.min-1) did not show any significant difference from that during saline and iloprost infusion (0.7 ng.kg-1.min-1) in healthy subjects and diabetic patients. CONCLUSIONS Iloprost infusion improves insulin action in healthy subjects and NIDDM patients.

Abstract
Many recent studies have identified biometric parameters which can be used as screening factors in the diagnosis of chromosomic anomalies. This derives from the assertion that karyotype testing in over-35-year-old women alone only allows 20-30% of fetuses suffering from chromosomic anomalies to be diagnosed. The majority of these fetuses remain undiagnosed during the prenatal period given that a high percentage of younger women are excluded from screening. For a long time researchers have hoped to introduce the assay of clinical and instrumental parameters thus allowing anomalous fetuses to be diagnosed in under-35-year-old women. It is now possible to define a biochemical parameter in maternal sera which can identify women at risk and refer them for cytogenetic tests: AFP assay and still more recently the contemporary assay of AFP, estriol and beta-HCG allows greater diagnostic accuracy. However, even using this method only part of those fetuses with chromosomic alterations are identified. Since it is unlikely that screening could be performed without indications in the under 35-year-old age group, it is important to identify routine echographic parameters which can then serve as the indication for subsequent cytogenetic tests and a definitive diagnosis. In this way, by integrating ultrasonographic examination, using biometric and morphological tests, with a biochemical evaluation it will be possible to achieve a higher percentage of diagnosis. This paper examines the most common malformations including trisomy 13, trisomy 18 and trisomy 21 syndromes, Turner's syndrome and triploidy, together with the main echographic findings which accompany them.

Abstract
Ten healthy subjects and 30 non-insulin-dependent (type II) diabetic patients matched for age, gender ratio, body mass index, lean body mass (LBM), waist to hip ratio, and arterial blood pressure volunteered for the study. In all subjects, fasting plasma free radical (O2-) levels and basal membrane lipid fluidity (MLF) and protein mobility (MPM) were determined. The whole group of subjects underwent a euglycemic hyperinsulinemic glucose clamp with simultaneous indirect calorimetry for substrate oxidation determination. Diabetic patients versus controls displayed higher fasting plasma glucose (8.3 +/- 0.4 v 5.1 +/- 0.4 mmol/L, P +/- .001), O2- (0.48 +/- 0.02 v 0.16 +/- 0.02 mumol/L x min), and hemoglobin A1c ([HbA1C] 7.9% +/- 0.4% v 5.7% +/- 0.3%, P < .03) levels and a stronger reduction in basal MLF (0.243 +/- 0.006 v 0.318 +/- 0.009, P < .003) and basal MPM (0.348 +/- 0.003 v 0.518 +/- 0.010, P < .002). Whole-body glucose disposal (WBGD) and oxidative and nonoxidative glucose metabolism were also significantly lower in diabetics than in controls. In diabetic patients (n = 30), plasma O2- levels correlated with basal MLF (r = -.59, P < .005), basal MPM (r = -.84, P < .001), fasting plasma insulin level (r = .51, P < .004), WBGD (r = -.53, P < .002), and nonoxidative (r = -.45, P < .01) glucose metabolism. In conclusion, our results demonstrate that a relationship between plasma O2- levels and insulin action occurs in non-insulin-dependent diabetics.
