Management of surgical diseases of thyroid gland indications of the United Italian Society of Endocrine Surgery (SIUEC).

A task force of the United Italian society of Endocrine Surgery (SIUEC) was commissioned to review the position statement on diagnostic, therapeutic and health­care 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.

An international Delphi study on the burden of allergic rhinoconjunctivitis and urticaria and the role of bilastine among current treatment options.

BACKGROUND: Allergic rhinoconjunctivitis and chronic urticaria are common histamine-driven diseases, exerting detrimental effects on cognitive functions, sleep, daily activities, and quality of life. Non-sedating second-generation H1-antihistamines are the first-line treatment of choice. Aim of the study was to define the role of bilastine among second-generation H1-antihistamines in the treatment of allergic rhinoconjunctivitis and urticaria in patients of different ages. METHODS: An international Delphi study was carried out to assess consensus among experts from 17 European and extra-European countries on three main topics: 1) Burden of disease; 2) Current treatment options; 3) Specific characteristics of bilastine among second-generation antihistamines. RESULTS: Here, we present the results obtained for a selection of 15 out of 27 consensus statements, focused on disease burden, role of second-generation antihistamines and bilastine profile. The rate of concordance was ≥98% for 4 statements, ≥ 96% for 6, ≥ 94% for 3, and ≥90% for 2. CONCLUSIONS: The high degree of agreement obtained suggests a wide awareness of the burden of allergic rhinoconjunctivitis and chronic urticaria among experts from all over the world and reflects a broad consensus on the role of second-generation antihistamines in general and of bilastine in particular for their management.

Is absorbable mesh useful in preventing parastomal hernia after emergency surgery? The PARTHENOPE study.

PURPOSE: Colostomy is a frequent event in oncological or inflammatory bowel diseases. Its related morbidity includes retraction, infection and parastomal hernia (PH), which is a quite common late complication. Several surgical options are available for PH repair, the majority including mesh. However, results are often disappointing with relevant recurrence rates, up to 33%. The study aim was to assess the feasibility and effectiveness of prophylactic biosynthetic mesh (BIO-A®, polyglycolide-trimethylene carbonate copolymer) placed during colostomy fashioning, in reducing PH. A prospective randomized controlled double-blind trial was conducted from January 2014 to December 2019 to compare conventional end-colostomy with end-colostomy reinforced with BIO-A mesh in ante-rectus position in patients undergoing colon diversion in emergency surgery. METHODS: Patients were clinically followed up at 3, 6, and 12 months and received a CT scan at 6 and 12 months. The postoperative morbidity and wound events were also evaluated. RESULTS: 55 patients receiving conventional colostomy considered as Control Group and 55 patients receiving BIO-A mesh supported colostomy (Mesh Group) were included in the study. At 12 months, the incidence of PH was 9 (12.7%) and 24 (43.6%) in the Mesh Group and Control Group, respectively (p < 0.05). Postoperative morbidity was similar between Mesh Group and Control Group (7 [12.7%] vs 4 [7.3%], respectively; p = 0.340). The multivariable analysis showed that not using a mesh (p = 0.042), age > 70 years (p = 0.041), diabetes (p < 0.001), colon dilation > 7 cm (p < 0.0001) and COPD (p = 0.009) were all related with postoperative PH. CONCLUSIONS: The prophylactic BIO-A mesh positioning during colostomy is an effective procedure reducing PH incidence at a 1 years follow-up guaranteeing low postoperative morbidity.

Onset of Nut Allergy in a Pediatric Cohort: Clinical and Molecular Patterns in the AFRUSEN Study.

BACKGROUND AND OBJECTIVE: Nut allergy is a growing problem, yet little is known about its onset in children. Objective: To characterize the onset of nut allergy in children in southern Europe. METHODS: The study population comprised consecutive patients up to 14 years of age who visited allergy departments with an initial allergic reaction to peanut, tree nut, or seed. The allergy work-up included a clinical history, food challenge, skin prick testing, determination of whole-extract sIgE, and ImmunoCAP ISAC-112 assay. RESULTS: Of the 271 children included, 260 were first diagnosed with nut allergy at a mean age of 6.5 years and at a mean (SD) of 11.8 (21.2) months after the index reaction. The most common culprit nuts at onset were walnut (36.5%), peanut (28.5%), cashew (10.4%), hazelnut (8.5%), pistachio (5.4%), and almond (5%). Onset of peanut allergy was more frequent in children ≤6 years and walnut in those aged >6 years (P=.032). In 65% of cases, the allergic reaction occurred the first time the patient consumed the nut, and 35% of reactions were anaphylactic. Overall, polysensitization to nuts was detected by skin prick testing in 64.9% of patients, although this rate was lower among walnut-allergic children (54.7%) and peanut-allergic children (54.1%) (P<.0001). Sensitization to 2S albumins was predominant (75%), especially Jug r 1 (52.8%), whereas sensitization to lipid transfer proteins was less relevant (37%). CONCLUSION: In the population we assessed, the onset of nut allergy occurred around 6 years of age, slightly later than that reported in English-speaking countries. Walnut was the main trigger, followed by peanut. 2S albumin storage proteins, especially Jug r 1, were the most relevant allergens. This study will help guide management and may contribute to preventive strategies in pediatric nut allergy.

Antecedentes: La alergia a frutos secos es un problema creciente. Sin embargo, existe poca información relativa al inicio de su establecimiento en la población infantil. Objetivos: Describir el debut de alergia a frutos secos en niños del sur de Europa. Métodos: Se incluyeron pacientes de hasta 14 años que acudieron de forma consecutiva a la consulta de alergia debido a una reacción inicial con cacahuete, frutos secos o semillas. El estudio alergológico incluyó realización de historia clínica, provocación oral, prueba intraepidérmica (SPT), determinación de IgE específica para extracto completo y mediante ImmunoCAP ISAC-112. Resultados: De los 271 niños incluidos, 260 se diagnosticaron de alergia a frutos secos por primera vez a los 6,5 años de media, habiendo tenido la reacción índice 11,8 (±21,2SD) meses antes. Los frutos secos responsables en el debut fueron nuez (36,5%), cacahuete (28,5%), anacardo (10,4%), avellana (8,5%), pistacho (5,4%) y almendra (5%). La instauración de la alergia a cacahuete fue más frecuente en niños ≤6 años y para nuez en >6 años (p=0,032). En el 65% de los casos, la reacción alérgica sucedió en la primera vez en que el paciente consumía el fruto seco, y el 35% de las reacciones fueron anafilaxia. En conjunto, la polisensibilización a frutos secos se identificó en el 64,9% de los pacientes, aunque este porcentaje fue significativamente inferior en niños alérgicos a nuez (54,7%) y cacahuete (54,1%) (p<0,0001). La sensibilización a albúminas 2S fue predominante (75%), especialmente a Jug r 1 (52,8%), mientras que la identificación de LTP fue menos relevante (37%). Conclusión: En nuestra población, el debut de alergia a frutos secos sucedió alrededor de los 6 años de edad, ligeramente más tardío al reportado en países anglosajones. La nuez fue el principal desencadenante, seguido de cacahuete, y las albúminas de almacenamiento 2S, especialmente Jug r 1, fueron los alérgenos más relevantes (AU)

Combination of ultrasound and molecular testing in malignancy risk estimate of Bethesda category IV thyroid nodules: results from a single-institution prospective study.

PURPOSE: Malignancy prediction in indeterminate thyroid nodules is still challenging. We prospectively evaluated whether the combination of ultrasound (US) risk stratification and molecular testing improves the assessment of malignancy risk in Bethesda Category IV thyroid nodules. METHODS: Ninety-one consecutively diagnosed Bethesda Category IV thyroid nodules were prospectively evaluated before surgery by both ACR- and EU-TIRADS US risk-stratification systems and by a further US-guided fine-needle aspiration cytology (FNAC) for the following molecular testing: BRAFV600E, N-RAS codons 12/13, N-RAS codon 61, H-RAS codons 12/13, H-RAS codon 61, K-RAS codons 12/13, and K-RAS codon 61 point-mutations, as well as PAX8/PPARγ, RET/PC1, and RET/PTC 3 rearrangements. RESULTS: At histology, 37% of nodules were malignant. No significant association was found between malignancy and either EU- or ACR-TIRADS. In total, 58 somatic mutations were identified, including 3 BRAFV600E (5%), 5 N-RAS 12/13 (9%), 13 N-RAS 61 (22%), 7 H-RAS 12/13 (12%), 11 H-RAS 61 (19%), 6 K-RAS 12/13 (10%), 8 K-RAS 61 (14%) mutations and 2 RET/PTC1 (4%), 0 RET/PTC 3 (0%), 3 PAX8/PPARγ (5%) rearrangements. At least one somatic mutation was found in 28% and 44% of benign and malignant nodules, respectively, although malignancy was not statistically associated with the outcome of the mutational test. However, the combination of ACR-, but not EU-, TIRADS with the presence of at least one somatic mutation, was significantly associated with malignant histology (P = 0.03). CONCLUSION: US risk stratification and FNAC molecular testing may synergistically contribute to improve malignancy risk estimate of Bethesda category IV thyroid nodules.

Thyroid surgery during coronavirus-19 pandemic phases I, II and III: lessons learned in China, South Korea, Iran and Italy.

OBJECTIVE: We compared demographic and clinic-pathological variables related to the number of surgeries for thyroid conditions or for cancer, morbidity, and fine needle aspiration (FNA) practices among Covid19 pandemic phases I, II, III and the same seasonal periods in 2019. METHODS: The prospective database of the Division of Thyroid Surgery, China-Japan Union Hospital of Jilin University, Changchun, China was used for this study. Covid19 emergency levels were stratified according to the World Health Organization: phase I (January 25-February 25, 2020), phase II (February 26-March 19), phase III (March 20-April 20). RESULTS: There were fewer outpatient FNAs and surgeries in 2020 than in 2019. There were no thyroid surgeries during phase I. There were also fewer surgeries for cancer with a significant reduction of advanced stage cancer treatments, mainly stage T1b N1a in phase II and T3bN1b in phase III. Operative times and postoperative stays were significantly shorter during the pandemic compared to our institutional baseline. In phase III, vocal cord paralysis (VCP) increased to 4.3% of our baseline numbers (P = 0.001). There were no cases of Covid19-related complications during the perioperative period. No patients required re-admission to the hospital. CONCLUSION: The Covid19 outbreak reduced thyroid surgery patient volumes. The decrease of Covid19 emergency plans contributed to unexpected outcomes (reduction of early stage cancer treatment, decreased operative times and hospital stays, increased VCP rate).

[Impact of the COVID-19 pandemic on the training of Spanish neurology residents]. / Repercusión de la pandemia por COVID-19 en la formación de los residentes de neurología españoles.

Introduction: The COVID-19 pandemic has transformed medical practice and severely disrupted the training of medical residents worldwide. The Spanish Society of Neurology conducted a study to assess its impact on the training of neurology residents in Spain. Methods: We performed a descriptive, cross-sectional study through a survey distributed by e-mail to all neurology residents belonging to the Society. The survey included questions on demographic variables, care activity, and personal and educational impact of the pandemic, as well as respondents' expectations for the future of their work in the post-pandemic era. Results: Of 422 surveys sent, we received a total of 152 responses (36%); 79 respondents (52%) were women and 73 (48%) were men. By year of residency, 51 respondents (33.6%) were in the fourth year, 45 (29.6%) in the third year, 28 (18.4%) in the second year, and 28 (18.4%) in the first year. A total of 139 respondents (90.8%) reported changes in hospital activity, and 126 (82.8%) considered the situation to have had a negative impact on their training, with 99 (64.7%) having lost non-recoverable rotations. Sixty-six percent of respondents (n=101) expressed a desire to extend their residency period. Conclusions: The pandemic has had an extremely severe impact on all areas of the health system, with trainee physicians being one of the most affected groups. Among neurology residents, the crisis has caused significant shortcomings in their training and clinical activities, through the suspension of specific rotations. A high percentage of respondents wished to extend the residency period.

Contraindications to immunotherapy: a global approach.

BACKGROUND: Recommendations on contraindications to allergen immunotherapy (AIT) have been independently developed by National and International Societies/Academies. AIT contraindications are mainly based on case reports, case-series, or experts' opinion, while evidence-based information is limited. The aim of the present review was to describe existing guidelines on contraindications to AIT and to highlight differences between them. MAIN BODY: An extended review of the literature regarding contraindications to AIT for respiratory allergy and venom hypersensitivity was performed. Furthermore, Societies and Academies registered in the World Allergy Organization and EAACI databases, were asked for additional information. Only AIT guidelines published under official auspicies were included. A large heterogeneity among the various recommendations on contraindications was registered. Common contraindications to most of the guidelines were: lack of adherence, pregnancy before the start of AIT, the use of beta-blockers, certain age groups, uncontrolled asthma, autoimmune diseases and malignancies. CONCLUSION: As new data arise, revisions might soon be needed allowing AIT in the cases of patients treated with ACE inhibitors and beta-blockers, in elderly patients and in patients with concomitant autoimmune diseases and neoplasias in remission. The decision to prescribe AIT is always tailor-made, balancing risk vs benefit. Creating globally accepted guidelines would help Allergologists in their decision making.

IONM and thyroidectomy in benign thyroid disease. Analysis of adverse events.

OBJECTIVES: The aim of this study is to identify statistically significant differences in the onset of postoperative complications in patients undergoing thyroid surgery for benign pathology, following the systematic introduction of intraoperative neuromonitoring (IONM) of the laryngeal nerves. MATERIALS AND METHODS: In this study we have retrospectively analysed data of 604 consecutive patients underwent to thyroidectomy in the Unit of General Surgery - University Hospital of Parma between January 2011 and December 2017. All patients were divided in two groups: the first group of patients was operated without the use of IONM (Group A) the second group was operated after the introduction of the systematic use of IONM (Group B). We have compared the incidence of adverse events in these two groups, analysing the impact of IONM on the onset of the most frequent complications after thyroid surgery. We have considered the impact of other variables in both groups, such as thyroiditis, hyperfunction and gland sinking in mediastinum. RESULTS: No statistically significant differences in the incidence between Group A (patients operated without the use of IONM) and Group B (patients operated with the use of IONM) were detected, though a decreasing trend after the introduction of IONM was observed. No statistically significant differences were reported even analysing the influence of other patient's variables such as thyroiditis, hyperfunction and glandular sinking in mediastinum. CONCLUSION: Even if the number of patients considered is not sufficient to value statistically significant differences, the decreasing trend of the incidence of postoperative complications after introduction of IONM encourage us. The surgeon expertise is still the most relevant variable influencing the decreasing of postoperative complications, underlining the importance of the centralization of this kind of surgery in the high volume centres.

Early diagnosis of anastomotic leakage after colorectal surgery by the Dutch leakage score, serum procalcitonin and serum C-reactive protein: study protocol of a prospective multicentre observational study by the Italian ColoRectal Anastomotic Leakage (iC.

BACKGROUND: Anastomotic leakage (AL) is a dreaded major complication after colorectal surgery. There is no uniform definition of anastomotic dehiscence and leak. Over the years many risk factors have been identified (distance of anastomosis from anal verge, gender, BMI, ASA score) but none of these allows an early diagnosis of AL. The DUtch LeaKage (DULK) score, C reactive protein (CRP) and procalcitonin (PCT) have been identified as early predictors for anastomotic leakage starting from postoperative day (POD) 2-3. The study was designed to prospectively evaluate AL rates after colorectal resections, in order to give a definite answer to the need for clear risk factors, and testing the diagnostic yeld of DULK score and of laboratory markers. Methods and analysis. A prospective enrollment for all patients undergoing elective colorectal surgery with anastomosis carried out from September 2017 to September 2018 in 19 Italian surgical centers. OUTCOME MEASURES: preoperative risk factors of anastomotic leakage; operative parameters; leukocyte count, serum CRP, serum PCT and DULK score assessment on POD 2 and 3. Primary endpoint is AL; secondary endpoints are minor and major complications according to Clavien-Dindo classification; morbidity and mortality rates; readmission and reoperation rates, length of postoperative hospital stay (Retrospectively registered at ClinicalTrials.gov Identifier: NCT03560180, on June 18, 2018). Ethics. The ethics committee of the "Comitato Etico Regionale delle Marche - C.E.R.M." reviewed and approved this study protocol on September 7, 2017 (protocol no. 2017-0244-AS). All the participating centers submitted the protocol and obtained authorization from the local Institutional Review Board.
