Abstract
BACKGROUND The assessment and management of adult dysphagia in South Africa is complex as appropriate intervention requires a balance of theoretical knowledge and critical thinking to ensure service delivery is appropriate within a resource-constrained health care system. Critical thinking involves the skilful evaluation of information to make informed decisions for effective assessment and intervention. It is imperative for Speech-Language Pathologists (SLPs) to cultivate these skills from an early stage in their careers. This study therefore aims to investigate the factors perceived to enhance critical thinking to shed light on how students transition theory into clinical decision-making. This is vital to inform future practice in the realm of dysphagia and to enhance Speech Therapy education. METHODS A qualitative research design was utilised to identify what facilitators assist SLP students to develop critical thinking skills in adult dysphagia. Data were gathered from students across three universities. Fifteen participants answered a self-developed online survey, and of those, four participated in a follow-up focus group. The data were analysed using a top-down approach and reflexive thematic analysis. RESULTS AND DISCUSSION The results revealed that viewing videos on instrumental assessment measures, case studies and peer learning were perceived to expand critical thinking theoretically. Similarly, critical thinking was best supported in clinical contexts, which provided opportunities to observe expert clinicians at the bedside, obtain individual feedback and access supervision. CONCLUSION The findings yielded recommendations for clinical educators involved in dysphagia training. This is necessary to better prepare SLP students to provide contextually relevant and responsive dysphagia services.

Abstract
The neuropsychological rehabilitation in our mental health service is a central pillar of psychosocial rehabilitation. These interventions are integrated into a more complex program of psychosocial rehabilitation based on cognitive behavioral method.We devote particular attention to the empowerment of the cognitive functions: attention, memory, language, logical and abstract reasoning.The aim of this research is to evaluate efficacy of neuropsycological rehabilitation training in cognitive rehabilitation of psychotic patients.The subjects that took part to the training were psychotics patient, residents in a mental health Community. Patients were both females and males, aged between 18 and 55 years. They were divided in two experimental groups and a control group. The instrument used was a battery of neuropsycological standardized tests. Tests were managed by an eye-tracker specialist.Preliminary results seem to confirm a certain degree of improvement due to the training. Eye tracking integration during assessment appears to be a powerful tool as well, in order to define more patient-tailored strategies.The training based on the empowerment of cognitive functions (attention, memory, language, logical and abstract reasoning) seems to change significantly the cognitive functions of the psychotic patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
There is a physical world and a world of meanings, symbols and social relationships. Neuroscience considers brain as a biological machine. Social science studies the human relationships.Nowadays we know cerebral processes underlying several aspects of social behavior.Cerebral damages or dysfunctions can influence the social behavior, as well as the social experiences can shape the development, structuring and functioning of the brain and, consequently, condition the further responses of the individuals to the social events. Humans are embodied subject. In an objective sense we are bodies with a brain, in a subjective sense we are individuals in a social world. This is a relevant matter for all the medical sciences, not only for psychiatry.The real-life functioning of individuals with schizophrenia shows deficits in several daily-life abilities, in social relationships and in the work activities. According to literature and clinical practice, basic criterions are: bio-psycho-social vulnerability, stressful life events, coping strategies as well as social and relational competence.Neurocognitive activity shows a straight correlation, albeit indirect, with the real-life functioning. Positive symptoms, negative symptoms and disorganized behavior can considerably influence the real-life functioning. While social and relational competence, the general functioning and resilience are protective factors that can positively condition real-life functioning. Moreover, welfare services (i.e. assisted job placement; disability subsidies; etc.) and a good family and social network can considerably influence the results.According to the results above, we can affirm the importance to adopt integrated and personalized therapeutic-rehabilitative program for the treatment of schizophrenia and other serious mental disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
The three members of the Aurora kinase family, Aurora-A, -B and -C, regulate several aspects of the mitotic process, and their aberrant expression and/or function causes mitotic abnormalities leading either to cell death or aneuploidy. They are found overexpressed in several human malignancies, including the papillary thyroid carcinoma (PTC). In the present study, we sought to establish whether Aurora kinase inhibition could be of any therapeutic value in the treatment of aggressive forms of PTC, enduring to radioactive iodide (RAI) ablation. To this end, the effects of selective inhibitors of Aurora-A (MLN8237) and Aurora-B (AZD1152) were analyzed on 3 human PTC cell lines expressing either wild-type (K1 and TPC1) or mutant p53 (BCPAP). The two inhibitors were capable of reducing cell proliferation in a time- and dose-dependent manner, with IC₅₀ comprised between 65.4 and 114.9 nM for MLN8237, and between 26.6 and 484.6 nM for AZD1152. Immunofluorescence experiments confirmed that AZD1152 inhibited Aurora-B phosphorylation of histone H3 on Ser10, however, it did not affect Aurora-A autophosphorylation. MLN8237 inhibited Aurora-A autophosphorylation as expected, but at concentrations required to achieve the maximum antiproliferative effects it also abolished H3 (Ser10) phosphorylation. Time-lapse videomicroscopy evidenced that both inhibitors prevented the completion of cytokinesis, and cytofluorimetric analysis showed accumulation of cells in G2/M phase and/or polyploidy. Apoptosis was induced in all the cells by both inhibitors independently from the p53 status. In conclusion, in the present preclinical study MLN8237 and AZD1152 have emerged as promising drug candidates for RAI-insensitive PTC.

Abstract
Small Ubiquitinlike MOdifier (SUMO) proteins are small protein modifiers capable of regulating cellular localization and function of target proteins. Over the last few years, a relevant role has been demonstrated for sumoylation in the modulation of important cellular processes, including gene transcription, DNA repair, cell-cycle regulation and apoptosis. Components of the sumoylation machinery have been found deregulated in different human cancers, and are thought to significantly affect cancer cell progression. In the present study we sought to analyze the expression of all the components of the sumoylation machinery in a case study comprising 77 papillary thyroid cancers (PTC) and normal matched tissues. In particular, we evaluated the expression of the SENP1 to SENP8 (SENtrin-specific proteases), SAE1 (SUMO1 activating enzyme subunit 1), UBA2 (UBiquitin-like modifier activating enzyme 2), UBC9 (UBiquitin conjugating enzyme 9), RanBP2 (RAN binding protein 2), MSMCE2 (Non- SMC element 2), CBX4 (ChromoBoX homolog 4), PIAS1 to PIAS4 (protein inhibitor of activated STAT), ZMIZ1 (zinc finger, MIZ-type containing 1) and ZMIZ2 (Zinc finger, MIZ-type containing 2) by means of quantitative RT-PCR. In most of the PTC examined we observed a significant alteration in the mRNAs of SENP8, ZMIZ1, SAE1, PIAS1 and PIAS2. These tended to be reduced in about 50 to 66% of cases, and unchanged or increased in the remaining ones. Univariate and Kaplan-Mayer analyses documented the lack of association between the expression of the above 5 genes and clinicopathological parameters. Only SAE1 was significantly higher in female PTC tissues, in respect to male PTC tissues (p=0.021), and SENP8 was significantly lower in TNM stages III-V, with respect to stages I-II (p=0.047). In conclusion, we demonstrated that the expression of SENP8, SAE1, PIAS1, PIAS2 and ZMIZ1 is deregulated in the majority of PTC tissues, likely contributing to the PTC phenotype. However, differently from other human cancers, their mRNA level does not represent a prognostic biomarker in PTC patients.

Abstract
Elastofibroma Dorsi (EFD) is a rare pseudo-tumor characterized by the overgrowth of elastic fibers mixed to adipose and connective tissues typically growing in the subscapular region. This can be bilateral but only rarely synchronous affecting different anatomical sites at the same time. Hereby we present a case of a 42-year-old male patient found with three different metachronous elastofibromas: bilateral EFD and a further third localization by the right elbow. The two EFs in the subscapular region were resected. After surgery pain reoccurred on the right side. This required the implantation of a spinal electro-stimulator. The elbow lesion was not excised as it was asymptomatic.

Abstract
OBJECTIVES Graves' disease (GD) is the most common cause of hyperthyroidism, and accounts worldwide for 60-80% of all cases. The diagnosis is based on clinical findings, and is confirmed by the presence of TRAB, suppression of TSH, and elevation of free thyroxin (free T4), and triiodinethyronin (free T3). GD can be treated by antithyroid drugs, radioactive iodine, or surgery. The aim of this study was to review retrospectively the surgical management, in terms of safety and efficacy, in 50 patients operated in the Department of Surgical Sciences since 2005 through 2010 and followed up at the Endocrinology Unit A of the Experimental Medicine Department. We assessed postoperative complications, which included the presence, persistence and development of ophthalmopathy, transient hypocalcemia, permanent hypoparathyroidism and recurrent laryngeal nerve palsy. MATERIALS AND METHODS We analyzed data from 50 patients with GD who were eligible and underwent Total Thyroidectomy (TT). Thirty-nine patients underwent TT for recurrent hyperthyroidism after medical therapy and eleven patients for severe ophtalmopathy. The mean follow up was 41 months (range: 10-70). RESULTS Eleven patients had ophtalmopathy before surgery. Four patients developed an ophtalmopathy after surgery. Eleven patients presented hypocalcemia, transient in ten patients and permanent in one patient. Five patients developed a transient disphony. Conclusions. Total thyroidectomy is a safe and radical procedure in Graves' disease treatment. Complications of TT are not different than subtotal thyroidectomy if it's performed by expert surgeons.

Abstract
The anaplastic thyroid cancer (ATC) is among the most aggressive human tumors which fail to respond to all the currently available therapeutic approaches. As a consequence most patients die within a few months from diagnosis. In the present preclinical study, the effects of the ZM447439, a functional inhibitor of Aurora kinases, on the growth and tumorigenicity of a panel of ATC derived cell lines (CAL-62, 8305C, 8505C and BHT-101) were evaluated. The treatment of the different ATC cells with ZM447439 inhibited proliferation in a time- and dose-dependent manner, with IC50 comprised between 0.5 mM and 5 mM. Moreover, the drug remarkably impaired the formation of colonies in soft agar of all the cell lines. Consistently with Aurora inhibition, immunofluorescence and immunoblotting experiments demonstrated that Aurora auto-phosphorylation following drug treatment was completely abrogated, and treated cells were characterized by the presence of multiple spindles with short microtubules. In the same experiments we observed the loss of histone H3 phosphorylation on Ser10, specifically due to Aurora-B, after ZM447439 treatment. Time-lapse videomicroscopy and flow cytometric analysis demonstrated that in presence of ZM447439 the cells were able to enter mitosis but not to complete it, becoming polyploid. Almost all the ATC cell lines studied showed increased apoptosis after only 48 h of treatment. In conclusion, our data demonstrate that ZM447439 is effective in reducing cell growth and tumorigenicity of different ATC derived cell lines, and further investigations are needed to exploit its potential therapeutic value for ATC treatment.

Abstract
Fine needle aspiration cytology (FNAC) is the more accurate diagnostic method for cervical lymph node (CLN) metastasis from differentiated thyroid cancers (DTC). However, FNAC diagnosis of cystic CLN is, in most cases, uninformative due to inadequate cellularity. Recently, thyroglobulin (Tg) detection in FNAC needle washout fluid has been shown to improve the diagnostic accuracy of FNAC, and its routine association with cytology is recommended. We here describe the case of a 20 yr old girl complaining of the recent appearance of palpable non-painful laterocervical nodes in the neck. Ultrasound examination revealed the presence of 3 cystic CLNs and 2 mixed thyroid nodules, with the larger one showing irregular margins. On the latter, and on 2 larger CLNs, FNAC was performed, and both Tg protein and mRNA were determined in the needle washout. The cytological analysis was not diagnostic for the two CLNs, while that of the thyroid nodule reported the presence of colloid and groups of thyrocytes with normal morphology. Both CLNs showed, however, high levels of Tg protein and were positive for Tg mRNA, suggestive of metastatic DTC. Based on these findings, the FNAC analysis was performed on the second smaller thyroid nodule suggesting (Tir4) the presence of PTC. The patient was then subjected to total thyroidectomy with lymph nodes resection of the central and homolateral compartments. The histological diagnosis confirmed the presence of a PTC in the small nodule and metastatic lymph nodes. In conclusion, this case confirms that the cytological diagnosis of cystic lymph nodes is challenging, and that the measurement of Tg protein and/or mRNA in the needle washout may overcome this limitation.

Abstract
Genetic instability, a hallmark of solid tumors including thyroid cancers, is thought to represent the mean by which premalignant cells acquire novel functional capabilities responsible for cancer cell growth and tumour progression. Over the last few years, the knowledge of the molecular processes controlling the mitotic phase of the cell cycle has increased considerably, and different mitotic proteins, whose expression or function has been found altered in human cancer tissues, have been associated to tumour genetic instability and aneuploidy. These include the three members of the Aurora kinase family (Aurora-A, -B and -C), serine/threonine kinases that regulate multiple aspects of chromosome segregation and cytokinesis. The genes encoding the Aurora kinases have been shown to induce cell malignant transformation, and their overexpression has been detected in several tumor derived cell lines and tissues, being often associated with a poor prognosis. Over the last decade, specific inhibitors of Aurora kinases exhibited in preclinical and early phase clinical studies a good therapeutic efficacy against several tumour types, including the highly aggressive anaplastic thyroid cancer and the medullary thyroid cancer. In the present review we'll first focus on the Aurora mitotic functions in normal cells; then we shall describe the main implications of their overexpression in the onset of genetic instability and consequent aneuploidy. We shall finally discuss on the effects of the functional inhibition of Aurora kinases on thyroid cancer cells growth and tumorigenicity.

Abstract
The urokinase plasminogen activator (uPA) system (uPAS) comprises the uPA, its cell membrane receptor (uPAR) and two specific inhibitors, the plasminogen activator inhibitor 1 (PAI-1) and 2 (PAI-2). The uPA converts the plasminogen in the serine protease plasmin, involved in a number of physiopathological processes requiring basement membrane (BM) or extracellular matrix (ECM) remodelling, including tumor progression and metastasis. The tumor-promoting role of PAS is not limited to the degradation of ECM and BM required for local diffusion and spread to distant sites of malignant cells, but widens to tumor cell proliferation, adhesion and migration, intravasation, growth at the metastatic site and neoangiogenesis. The relevance of uPAS in cancer progression has been confirmed by several studies which documented an increased expression of uPA, uPAR and PAI-1 in different human malignancies, and a positive correlation between the levels of one or more of them and a poor prognosis. For these reasons, the uPAS components have aroused considerable interest as suitable targets for anticancer therapy, and several pharmacological approaches aimed at inhibiting the uPA and/or uPAR expression or function in preclinical and clinical settings have been described. In the present manuscript, we will first glance at uPAS biological functions in human cancer progression and its clinical significance in terms of prognosis and therapy. We will then review the main findings regarding expression and function of uPAS components in thyroid cancer tissues along with the experimental and clinical evidence suggesting its potential value as molecular prognostic marker and therapeutic target in thyroid cancer patients.

Abstract
OBJECTIVES Aim of the study was to identify, in 59 operated patients affected by medullary thyroid carcinoma (MTC), the recurrence rate, survival, mortality and incidences of surgically derived hypoparathyroidism and recurrent laryngeal nerve injury (RLNI). MATERIALS AND METHODS Based on pre-surgical diagnosis of the 59 patients included in the study, 35 underwent total thyroidectomy with central neck dissection (Group A), 14 total thyroidectomy, central neck dissection and monolateral functional neck dissection (Group B) and 10 total thyroidectomy central neck dissection, bilateral functional neck dissection (Group C). Overall survival, recurrences, incidence of hypoparathyroidism and RLNI were evaluated. RESULTS The survival and recurrences were not statistically different among the three Groups. In Group B there was major probability of re-operation (p=0.042). The mortality rate was clearly major in Group C (p=0.003) due to the stage of pathology. Group C showed a high number of hypoparatiroidism compared to Group B, and B compared to A. In Group A there was only one unexpected RLNI; in 5 cases, 3 in Group B and 2 in Group C, there were a necessity laringeal section due to nerve tumor involvement. CONCLUSIONS From our data it appears clearly that disease outcome following the different surgical approaches is mainly determinated by the stage of the disease at diagnosis. However, the finding that patients in Group A and B showed a high rate of local-regional recurrences may suggest that homolateral lymphadenectomy in Group A patients and bilateral lymphadenectomy in Group B patients should be always performed.

Abstract
OBJECTIVES Anaplastic thyroid carcinomas (ATC) are highly aggressive tumours unresponsive to any available radio- or chemotherapeutic protocol, with a median survival rate of 4-5 months from the time of diagnosis. We previously demonstrated that ATC are characterized by increased expression of the kinases Aurora-A, -B and -C, involved in the regulation of multiple steps of the mitotic phase. In this study, the in vitro effects of SNS-314 mesylate, a pan-inhibitor of the Aurora kinases, on growth and tumorigenicity of ATC cells were evaluated. MATERIALS AND METHODS The effects of SNS-314 mesylate were assessed on the ATC derived cell lines CAL-62, 8305C, 8505C and BHT-101 by means of cell proliferation assay, immunofluorescence, cytofluorimetry, time lapse microscopy, and colony formation in soft agar. RESULTS Treatment of the different ATC cells with SNS-314 mesylate inhibited proliferation in a time- and dose-dependent manner, with IC(50) comprised between 2.6 nM and 26.6 nM. CAL-62 cells exposed for 24 h to SNS-314 mesylate 100 nM evidenced a significant augmentation of the apoptotic index. Time-lapse video-microscopy of CAL-62 cells showed that SNS-314 mesylate prevents the completion of mitosis leading to polyploidy. Western blot experiments demonstrated that the auto-phosphorylation of the Aurora kinases as well as histone H3 phosphorylation in CAL-62 treated cells was inhibited. Finally, the drug inhibited colony formation in soft agar of all cell lines. CONCLUSIONS Our results demonstrated that SNS-314 mesylate is capable to efficiently reduce cell growth and tumorigenicity of different ATC derived cell lines suggesting its potential therapeutic value for ATC treatment.

Abstract
OBJECTIVES Endovascular treatment (EVAR) of abdominal aortic aneurysm (AAA) is thought to be of benefit, particularly in patients aged ≥80 years. This issue was investigated in the present meta-analysis. DESIGN The study design involved a systematic review of the literature and meta-analysis. METHODS Systematic review of the literature and meta-analysis of data on elective EVAR vs. open repair of AAA in patients aged ≥80 years were performed. RESULTS Six observational studies reporting on 13,419 patients were included in the present analysis. Pooled analysis showed higher immediate postoperative mortality after open repair compared with EVAR (risk ratio 3.87, 95% confidence interval (CI) 3.19-4.68; risk difference, 6.2%, 95%CI 5.4-7.0%). The pooled immediate mortality rate after open repair was 8.6%, whereas it was 2.3% after EVAR. Open repair was associated with a significantly higher risk of postoperative cardiac, pulmonary and renal complications. Pooled analysis of three studies showed similar overall survival at 3 years after EVAR and open repair (risk ratio 1.10, 95%CI 0.77-1.57). CONCLUSIONS The results of this meta-analysis suggest that elective EVAR in patients aged ≥80 years is associated with significantly lower immediate postoperative mortality and morbidity than open repair and should be considered the treatment of choice in these fragile patients. These results indicate also that, when EVAR is not feasible, open repair can be performed with acceptable immediate and late survival in patients at high risk of aneurysm rupture.

Abstract
Rectal cancer is one of the most common malignancies in the western world population. The management of rectal cancer has changed thoroughly in recent years owing to the rapid advances in surgical techniques, imaging and adjuvant therapy. The present study analyses extensively 152 patients operated for diagnosis of, rectal cancer in the First Clinic of General Surgery UHC "Mother Theresa" in Tirana, Albania, in a ten years period. In the medical and operative records were analysed demographic, diagnostic, clinic, operative, pathology and postoperative patient's data. M : F ratio was 1,5:1. The average age of all patients was 59,8 ± 12,2 (29 - 79) years. 48% of all patients were of the age group 61 - 70 years. The diagnosis interval was 6 ± 4,6 months. The mean distance of tumor from the anal verge was 8,3 ± 4,2 (3,7 - 16) cm. 30% of all patients resulted stage D, according to the Astler - Coller classification. Overall operability index was 97,5%. 30 % of patients were treated with palliative operative procedures. 67,5% of all patients were treated with curative intent. The most common curative operation was low anterior resection with mesorectal excision in 76 patients (51%). The mean postoperative hospital stay was 12 ± 9,7 (3 - 45) days. Overall postoperative morbidity and mortality were 30% and 2,6% respectively. The surgical treatment of rectal cancer has changed radically in recent years in Albania. Relatively new surgical techniques, like low anterior resection and use of adjuvant chemoradiotherapy have improved the outcome, quality of life and survival of our patients.

Abstract
Angiomegaly is characterized by an alteration in the elastic component of arterial and venous vessels determining their elongation and tortuousness. This involves an increased risk of thromboembolism and aneurysmal degeneration in affected subjects, even if they have been asymptomatic for a long time. The aim of this study is to demonstrate the correlation between angiomegaly and aneurysmal disease. A total of 163 patients suffering from a peripheral arterial aneurysm were included, 74 of these with an iliac aneurysm, 41 with a femoral aneurysm and 48 suffering from popliteal aneurysm. All patients were examined by color Doppler ultrasonography (CDU) and angio-CT with contrast medium. Eighteen cases of arteriomegaly were diagnosed, and the prevalence in the examined population was 11%. This study demonstrates the close association existing between aneurysms in peripheral arteries and arteriomegaly. Peripheral arterial aneurysms in association with arteriomegaly involve an increased risk of complications like thrombosis, embolism and rupture. The showed familiarity in the arteriomegaly incidence leads to predisposition of screening programs, using CDU, among relatives of patients affected by arteriomegaly and/or peripheral arterial aneurysms.

Abstract
INTRODUCTION We have conducted a clinical controlled trial (CCT) on patients who had undergone thyroidectomy for goitre or thyroid carcinoma. The endpoint of this study was to evaluate the benefits of ultrasonic dissector vs conventional technique (vessel ligation and tight) in patients undergoing thyroid surgery. PATIENT AND METHODS Between January 2007 and December 2009 a CCT was conducted on 2.736 consecutive patients admitted to our clinical wards, who had undergone thyroidectomy for goitre or thyroid carcinoma. They were divided in two group: 1.021 patients (203 male and 818 female) underwent thyroidectomy with ultrasonic dissector (UAS) and 1.715 patients (369 male and 1.346 female) underwent throidectomy with conventional technique (vessel ligation and tight) (CT). RESULTS The operative time (UAS 80 minutes mean, 50 to 120 min., vs CT 120 minutes, 70 to 180 minutes) was much lower in the thryoidectomy with UAS group. The incidence of transient laryngeal nerve palsy (UAS 17/1.021 patients. 1.6% vs CT 16/1.715 patients, 0.9%) was higher in the thyroidectomy with UAS group; the incidence of permanent laryngeal nerve palsy was similar in two groups(UAS group; there are no relevant difference in the incidence of permanent hypocalcemia (UAS 26/1.021 patients, 2.5% vs 35/1.715 patients, 2%) which was similar in two groups. Also the average post-operative hospitalization was similar in two groups (2 days). CONCLUSIONS Actually, the only significant advantage shown from this CCT is represented in terms of cost-effectiveness (reduction of the usage of operating room and hospitalization) for patients treated with UAS, subsequent to the significant reduction of operative duration. Although the analysis showed that the patients who were treated with ultrasonic dissection don't present more favourable results in incidence of post-operative transient complication:transient laryngeal nerve palsy (1.6% in UAS vs 0.9% in CT) and transient hypocalcaemia (9.5% in UAS vs 7.7% in CT). There is no significant difference in the incidence of permanent laryngeal nerve palsy (0.9% in UAS vs in 1% CT). The experience of surgeon is the only important factor which can influence the appearance of these complications; the usage of Ultrasonic dissector can only help surgical action but can't repair the experience of the operator.

Abstract
The new staging technique of sentinel node biopsy facilitates the identification of pathological node negative patients in whom axillary dissection may be avoided; however, patients with a positive sentinel node biopsy would require a thorough examination of their nodal status. Axillary dissection provides good local control, accurate staging and prognostic information for decisions about adjuvant therapy. We describe a technique of radical axillary clearance that includes levels I, II and III; this isn't associated with additional morbidity to patients and involves minimal extension of operative time.
