Abstract
BACKGROUND Recognizing the parathyroid gland and distinguishing the parathyroid from thyroid lesions in fine needle aspiration (FNA) is challenging. This study aimed to identify cytomorphologic features suggestive of parathyroid origin and to assess the utility of cytopathology in conjunction with ancillary tests in the identification of parathyroid glands. MATERIALS AND METHODS Ultrasound (US) guided FNA of parathyroid gland and lesions in 81 patients were reviewed concerning clinical history and correlated to histopathologic findings in available cases. FNA smears were evaluated for cellularity, architectural patterns, cellular and nuclear features, and background of the smears. In 78 cases, FNA was supplemented by a measurement of parathormone (PTH) levels in the needle washout fluid (FNA-PTH assay) and/or GATA3/PTH/chromogranin-A immunostainings. RESULTS Sixty-four cases were diagnosed cytologically as parathyroid lesions in conjunction with FNA-PTH assay and/or immunocytochemical examinations. In an additional nine cases, a diagnosis of parathyroid lesions was rendered after repeated FNA with FNA-PTH assay. The histolopathologic diagnosis of surgically excised cases (n = 75) included parathyroid adenoma (60 cases), atypical parathyroid adenoma (4 cases), parathyroid hyperplasia (10 cases), and parathyroid carcinoma (1 case). Major cytological findings of parathyroid tissue included high cellularity, scattered naked nuclei, cribriform and three-dimensional clusters, stippled chromatin, and oxyphilic cytoplasm while papillary pattern or colloid-like material was identified in three cases respectively. No nuclear grooves or inclusions were seen in any case. CONCLUSIONS High cellularity scattered naked nuclei, cribriform and three-dimensional patterns, stippled chromatin and oxyphilic cytoplasm are cytomorphologic features that favour parathyroid origin. A combination of these features with FNA-PTH assay and/or GATA3, PTH, and chromogranin-A immunostainings on cytologic specimens aid in the identification of parathyroid glands and the distinguishing of parathyroid from thyroid lesions.

Abstract
OBJECTIVES Preoperative localization of pathological parathyroid glands with imaging is essential for focused unilateral neck exploration and minimally invasive techniques. Recently published studies suggested that contrast-enhanced ultrasonography (CEUS) had high accuracy in the localization of hyperfunctioning parathyroid glands, with a general increase in the sensitivity as compared to conventional sonography. The purpose of this study was to determine the usefulness of CEUS in the localization of parathyroid lesions relating to surgical and histopathological data, in comparison to color Doppler ultrasound (CDUS), in the same series of patients. METHODS Records of 142 patients who underwent parathyroidectomy were retrospectively examined comparing imaging and intraoperative/histopathologic findings. RESULTS The overall sensitivity of CEUS was 77.6% compared with 74.6% for CDUS, although no significative differences were found (P = .516). Conversely, CDUS has shown higher sensitivity than CEUS in the group of patients with associated thyroid pathology but there was no statistical difference (P = .529). The sensitivity for detection of multiple adenomas was the same for both procedures. CONCLUSIONS We found no significative superior sensitivity of CEUS also in case of concomitant thyroid pathology and multiple glands disease.

Abstract
Parathyroid imaging is essential for the detection and localization of hyperfunctioning parathyroid tissue in patients with primary hyperparathyroidism (pHPT). Surgical treatment of pHPT mainly consists of minimally invasive parathyroidectomy (MIP), as a single adenoma represents the most common cause of this endocrine disorder. Successful surgery requires an experienced surgeon and relies on the correct preoperative detection and localization of hyperfunctioning parathyroid glands. Failure to preoperatively identify the culprit parathyroid gland by imaging may entail a more invasive surgical approach, including bilateral open neck exploration, with higher morbidity compared to minimally invasive parathyroidectomy. Parathyroid imaging may be also useful before surgery in case of secondary hyperparathyroidism (sHPT) or hereditary disorders (MEN 1, 2, 4) as it enables correct localization of typically located parathyroid glands, detection of ectopic as well as supernumerary glands. It is now accepted by most surgeons experienced in parathyroid surgery that preoperative imaging plays a key role in their patients' management. Recently, the European Association of Nuclear Medicine (EANM) issued an updated version of its Guidelines on parathyroid imaging. Its aim is to precise the role and the advantages and drawbacks of the various imaging modalities proposed or well established in the preoperative imaging strategy. It also aims to favor high performance in indicating, performing, and interpreting those examinations. The objective of the present article is to offer a summary of those recent EANM Guidelines and their originality among other Guidelines in this domain issued by societies of nuclear medicine physicians or other disciplines.

Abstract
Importance Emerging computed tomographic (CT) imaging techniques for the localization of primary hyperparathyroidism (PHPT) may be superior to the current imaging standard, thus necessitating a critical review and pooling of available evidence. Objective Primary hyperparathyroidism requires accurate imaging to guide definitive surgical management. Advanced techniques including 4-dimensional computed tomographic (4D-CT) scan have been investigated over the past decade. We sought to evaluate the efficacy of these emerging imaging techniques through pooled analysis of the existing evidence. Data Sources PubMed, Embase, and Web of Science databases were queried for original English articles without any restrictions on date. Study Selection We included comparative observational studies but excluded animal studies, case reports, and case series. Overall, 353 abstracts were screened independently by 2 investigators along with a third reviewer to resolve conflicts. A total of 26 full-text articles were included in this review. Data Extraction and Synthesis This review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. Data was independently extracted by 2 investigators and subsequently pooled into a meta-analysis using a random-effects model. Main Outcomes and Measures Measures of imaging diagnostic performance such as sensitivity, specificity, positive predictive value, and negative predictive value were the primary outcomes of interest. Results Overall, of 34 articles screened, 26 met criteria for qualitative synthesis, and 23 of these were appropriate for meta-analysis. Of the 26 studies included, there were 5845 patients, of which 4176 were women (79.2%). The average of mean ages reported in 23 studies was 60.9 years. Meta-analysis in all patients with PHPT revealed pooled sensitivity that was greater with 4D-CT (81%; 95% CI, 77%-84%; I2 = 88%) compared with the current first-line modality of sestamibi-single-photon emission CT (SPECT/CT) (65%; 95% CI, 59%-70%; I2 = 93%). For patients with recurrent PHPT requiring reoperation, 4D-CT pooled sensitivity was 81% (95% CI, 64%-98%; I2 = 93%) in contrast to 53% (95% CI, 35%-71%; I2 = 81%) for sestamibi-SPECT/CT. The overall quality of the 26 studies was moderate with a median (range) Methodological Index for Nonrandomized Studies score for all included studies of 15.5 (13-19). Conclusions and Relevance The findings of this systematic review and with meta-analyses of numerous studies from the past decade suggest that the 4D-CT can be more sensitive and specific than sestamibi-SPECT/CT in localizing PHPT. More research is needed to determine the clinical significance of this improvement in localization.

Abstract
Intraoperative parathyroid hormone dosage allows real-time monitoring of the decrease in PTH levels during parathyroidectomy and verify procedure's efficacy. Currently, none of the interpretative criteria used has absolute accuracy. The aim of this study is to evaluate diagnostic accuracy of the Rome criterion verifying diagnostic significance of the individual assays. A total of 205 patients with primary hyperparathyroidism from a single adenoma were retrospectively evaluated and monitored with baseline PTH, PTH at 10 min and PTH at 20 min after adenoma excision. The accuracy of the latter two assays compared with baseline was compared by ROC curves. In addition, was evaluated the influence on these data of localization diagnostics (ultrasounds and scintigraphy), definitive histology, and type of surgery performed. The ratio of 20-min sampling to baseline in the Rome criterion showed highest diagnostic significance. This finding was not influenced by the type of surgery performed, definitive histologic examination, or intraoperative localization of the adenoma. The Rome criterion has shown its high reliability in detecting persistence. The ratio of sampling at 20 min to baseline is by far the best performing. Further studies are needed to evaluate whether sampling at 10 min after adenoma excision can be considered not mandatory.

Abstract
Preoperative localisation of pathological glands in patients with primary hyperparathyroidism (PHP) is the mainstay for mini-invasive parathyroidectomy. Nevertheless, a not negligible number of patients presents discordant or negative neck ultrasound (US) and 99mTc-Sestamibi (MIBI) scan. The aim of this study was to assess if a mini-invasive approach is feasible in this kind of patients. In this retrospective study were included patients that underwent parathyroidectomy for PHP. Patients were divided into two groups according to concordance of US and MIBI scan results. 242 patients were included: 183 had concordant preoperative studies, and 59 had discordant or negative studies. A mini-invasive approach was possible in 42 (72.9%) patients with unclear preoperative studies, whereas 12 (20.3%) additional patients required conversion to BNE. The incidence of persistent PHP was higher in patients with unclear preoperative studies (8.5% vs 2.7%), but this difference did not reach a statistical significance (p = 0.121). In patients with unclear preoperative studies, a negative result of intraoperative PTH allowed to avoid a persistent disease in 12 patients, while in 3 cases led to an unnecessary additional exploration. In patients with discordant preoperative studies a mini-invasive approach is feasible; in this setting, the use of intraoperative PTH is mandatory to reduce the incidence of persistent PHP.

Abstract
Chronic kidney disease mineral and bone disorder may persist after successful kidney transplantation. Persistent hyperparathyroidism has been identified in up to 80% of patients throughout the first year after kidney transplantation. International guidelines lack strict recommendations about the management of persistent hyperparathyroidism. However, it is associated with adverse graft and patient outcomes, including higher fracture risk and an increased risk of all-cause mortality and allograft loss. Secondary hyperparathyroidism may be treated medically (vitamin D, phosphate binders and calcimimetics) or surgically (parathyroidectomy). Guideline recommendations suggest medical therapy first but do not clarify optimal parathyroid hormone targets or indications and timing of parathyroidectomy. There are no clear guidelines or long-term studies about the impact of hyperparathyroidism therapy. Parathyroidectomy is more effective than medical treatment, although it is associated with increased short-term risks. Ideally parathyroidectomy should be performed before kidney transplantation to prevent persistent hyperparathyroidism and improve graft outcomes. We now propose a roadmap for the management of secondary hyperparathyroidism in patients eligible for kidney transplantation that includes the indications and timing (pre- or post-kidney transplantation) of parathyroidectomy, the evaluation of parathyroid gland size and the integration of parathyroid gland size in the decision-making process by a multidisciplinary team of nephrologists, radiologists and surgeons.

Abstract
Background and Objectives: preoperative differentiation of enlarged parathyroid glands may be challenging in conventional B-mode ultrasound. The aim of our study was to analyse qualitative and quantitative characteristics of parathyroid gland lesions, using multiparametric ultrasound protocol—B-mode, Colour Doppler (CD), and contrast-enhanced ultrasound (CEUS)—and to evaluate correlation with morphology in patients with hyperparathyroidism (HPT). Materials and Methods: consecutive 75 patients with 88 parathyroid lesions and biochemically confirmed HPT prior to parathyroidectomy were enrolled in the prospective study. B-mode ultrasound, CD, and CEUS were performed with the subsequent qualitative and quantitative evaluation of acquired data. We used 1 mL or 2 mL of intravenous ultrasound contrast agent during the CEUS examination. Correlation with post-surgical morphology was evaluated. Results: seventy parathyroid adenomas were hypoechoic and well contoured with increased central echogenicity (44.3%), peripheral-central vascularization (47%), and polar feeding vessel (100%). Twelve hyperplasias presented with similar ultrasound appearance and were smaller in volume (p = 0.036). Hyperplasias had a tendency for homogenous, marked intense enhancement vs. peripherally enhanced adenomas with central wash-out in CEUS after quantitative analysis. No significant difference was observed in contrasting dynamics, regardless of contrast media volume use (1 mL vs. 2 mL). We achieved 90.9% sensitivity and 72.7% specificity, 93% positive predictive value (PPV), 87.3% negative predictive value (NPV), and 87.3% accuracy in the differentiation of parathyroid lesions prior to post-processing. In a quantitative lesion analysis, our sensitivity increased up to 98%, specificity 80%, PPV 98%, and NPV 80% with an accuracy of 96.4%. Conclusions: CEUS of parathyroid lesions shows potential in the differentiation of adenoma from hyperplasia, regardless of the amount of contrast media injected. The quantitative analysis improved the sensitivity and specificity of differentiation between parathyroid lesions. Hyperplasia was characterized by homogeneous enhancement, fast uptake, and homogeneous wash-out appearance; adenoma—by peripheral uptake, central wash-out, and reduced hemodynamics. The use of CEUS quantification methods are advised to improve the ultrasound diagnostic role in suspected parathyroid lesions.

Abstract
Background The question of an optimal strategy and outcomes in COVID-19 tracheostomy has not been answered yet. The critical focus in our case study is to evaluate the outcomes of tracheostomy on intubated COVID-19 patients. Methods A multicentric prospective observational study of 1890 COVID-19 patients undergoing tracheostomy across 120 hospitals was conducted over 7 weeks in Spain (March 28 to May 15, 2020). Data were collected with an innovative approach: instant messaging via WhatsApp. Outcome measurements: complications, achieved weaning and decannulation and survival. Results We performed 1,461 surgical (81.3%) and 429 percutaneous tracheostomies. Median timing of tracheostomy was 12 days (4–42 days) since orotracheal intubation. A close follow-up of 1616/1890 (85.5%) patients at the cut-off time of 1-month follow-up showed that in 842 (52.1%) patients, weaning was achieved, while 391 (24.2%) were still under mechanical ventilation and 383 (23.7%) patients had died from COVID-19. Decannulation among those in whom weaning was successful (n = 842) was achieved in 683 (81%) patients. Conclusion To the best of our knowledge, this is the largest cohort of COVID-19 patients undergoing tracheostomy. The critical focus is the unprecedented amount of tracheostomies: 1890 in 7 weeks. Weaning could be achieved in over half of the patients with follow-up. Almost one out of four tracheotomized patients died from COVID-19.
