Review
Pheochromocytoma and paraganglioma (PPG) are rare and late-diagnosed catecholamine secreting tumors, which may be associated with unrecognized and/or severe cardiomyopathies. We performed a computer-assisted systematic search of the electronic Medline databases using the MESH terms "myocarditis," "myocardial infarction," "Takotsubo," "stress cardiomyopathy," "cardiogenic shock", or "dilated cardiomyopathy," and "pheochromocytoma" or "paraganglioma" from 1961 to August 2012. All detailed case reports of cardiomyopathy due to a PPG, without coronary stenosis, and revealed by acute symptoms were included and analyzed. A total of 145 cases reports were collected (49 Takotsubo Cardiomyopathies [TTC] and 96 other Catecholamine Cardiomyopathies [CC]). At initial presentation, prevalence of high blood pressure (87.7%), chest pain (49.0%), headaches (47.6%), palpitations (46.9%), sweating (39.3%), and shock (51.0%) were comparable between CC and TTC. Acute pulmonary edema (58.3% vs 38.8%, P = 0.03) was more frequent in CC. There was no difference in proportion of patients with severe left ventricular systolic dysfunction (LV Ejection Fraction [LVEF] < 30%) at initial presentation between both groups (P = 0.15). LVEF recovery before (64.9% vs 40.8%, P = 0.005) and after surgical resection (97.7% vs 73.3%, P = 0.001) was higher in the TTC group. Death occurred in 11 cases (7.6%). In multivariate analysis, only TTC was associated with a better LV recovery (0.15 [0.03-0.67], P = 0.03). Pheochromocytoma and paraganglioma can lead to different cardiomyopathies with the same brutal and life-threatening initial clinical presentation but with a different recovery rate. Diagnosis of unexplained dilated cardiomyopathy or TTC should lead clinicians to a specific search for PPG.

BACKGROUND
Congenital adrenal hyperplasia (CAH) is a group of genetic disorders that affects the adrenal glands and is the most common cause of primary adrenal insufficiency in children. In the past few decades, magnetic resonance imaging (MRI) has been implemented to investigate how the brain may be affected by CAH. A systematic review was conducted to evaluate and synthesize the reported evidence of brain findings related to CAH using structural, functional, and diffusion-weighted MRI.
METHODS
We searched bibliographical databases through July 2021 for brain MRI studies in individuals with CAH.
RESULTS
Twenty-eight studies were identified, including 13 case reports or series, 10 studies that recruited and studied CAH patients vs unaffected controls, and 5 studies without a matched control group. Eleven studies used structural MRI to identify structural abnormalities or quantify brain volumes, whereas 3 studies implemented functional MRI to investigate brain activity, and 3 reported diffusion MRI findings to assess white matter microstructure. Some commonly reported findings across studies included cortical atrophy and differences in gray matter volumes, as well as white matter hyperintensities, altered white matter microstructure, and distinct patterns of emotion and reward-related brain activity.
CONCLUSIONS
These findings suggest differences in brain structure and function in patients with CAH. Limitations of these studies highlight the need for CAH neuroimaging studies to incorporate larger sample sizes and follow best study design and MRI analytic practices, as well as clarify potential neurologic effects seen across the lifespan and in relation to clinical and behavioral CAH phenotypes.

The use of fluorescence in surgery has expanded and become widespread in recent years, which has led to a real technological phenomenon with the emergence of devices adapted for use in laparoscopic and robotic approaches. Fluorescence-guided surgery in the field of endocrine surgery is also on the rise. More and more articles describe its use in surgery of the thyroid, parathyroid and adrenal glands, although the series are still modest in size and protocols have not been standardized. There are currently several developing areas for the application of fluorescence in endocrine surgery, including the use of fluorescence with indocyanine green in adrenal gland surgery, the identification and prediction of parathyroid perfusion with indocyanine green, and autofluorescence of the parathyroid glands. The objective of this article is to review the current applications of fluorescence in endocrine surgery.

Coronaviruses are a big family of viruses that can infect mammalians and birds. In humans they mainly cause respiratory tract infections, with a large spectrum of severity, from mild, self-limited infections to highly lethal forms as severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV) and Coronavirus Disease 2019 (COVID-19). Scanty data are reported for the involvement of endocrine glands in human coronaviruses, in particular SARS-CoV-2. In this review, we summarize endocrinological involvement in human coronaviruses, including data on animal coronaviruses. Avians, ferrets and bovine are affected by specific coronavirus syndromes, with variable involvement of endocrine glands. SARS-CoV and SARS-CoV-2 use angiotensin-converting enzyme 2 (ACE2) as a target receptor, so ACE2 plays a central role in viral transmission and initial organ involvement. Autoptic studies on SARS patients revealed that thyroid, parathyroid, pituitary gland, endocrine pancreas and especially adrenals and testis could be impaired by different mechanisms (direct damage by SARS-CoV, inflammation, vascular derangement and autoimmune reactions) and few clinical studies have evidenced functional endocrine impairment. Only few data are available for COVID-19 and gonads and endocrine pancreas seem to be involved. International endocrinological societies have brought some recommendations for the COVID-19 pandemic, but further studies need to be performed, especially to detect long-term hormonal sequelae.

PURPOSE
Adrenal incidentalomas are being discovered with increasing frequency, and their discovery poses a challenge to clinicians. Despite the 2002 National Institutes of Health consensus statement, there are still discrepancies in the most recent guidelines from organizations representing endocrinology, endocrine surgery, urology and radiology. We review recent guidelines across the specialties involved in diagnosing and treating adrenal incidentalomas, and discuss points of agreement as well as controversy among guidelines.
MATERIALS AND METHODS
PubMed®, Scopus®, Embase™ and Web of Science™ databases were searched systematically in November 2019 in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement to identify the most recently updated committee produced clinical guidelines in each of the 4 specialties. Five articles met the inclusion criteria.
RESULTS
There is little debate among the reviewed guidelines as to the initial evaluation of an adrenal incidentaloma. All patients with a newly discovered adrenal incidentaloma should receive an unenhanced computerized tomogram and hormone screen. The most significant points of divergence among the guidelines regard reimaging an initially benign appearing mass, repeat hormone testing and management of an adrenal incidentaloma that is not easily characterized as benign or malignant on computerized tomography. The guidelines range from actively recommending against any repeat imaging and hormone screening to recommending a repeat scan as early as in 3 to 6 months and annual hormonal screening for several years.
CONCLUSIONS
After reviewing the guidelines and the evidence used to support them we posit that best practices lie at their convergence and have presented our management recommendations on how to navigate the guidelines when they are discrepant.

Meta-Analysis
PURPOSE
To evaluate the safety and clinical efficacy of image-guided radiofrequency ablation (RFA) in patients exhibiting adrenal metastatic tumors (AMTs).
METHODS
The PubMed, Web of Science, and Wanfang databases were searched for relevant studies published as of November 2022, and study results were pooled for subsequent analysis. The endpoints of this meta-analysis included primary and secondary technical success, local hemorrhage, pneumothorax, hypertensive crisis, local recurrence, and 1- and 3-year overall survival (OS) rates.
RESULTS
This analysis incorporated 11 studies enrolling 351 patients that underwent RFA treatment for 373 AMTs. The pooled primary and secondary technical success, local hemorrhage, pneumothorax, hypertensive crisis, local recurrence, and 1- and 3-year OS rates in these patients were 84%, 91%, 4%, 6%, 7%, 19%, 82%, and 46%, respectively. The 1-year OS ( = 75.2%, = 0.003) and 3-year OS ( = 81.4%, = 0.001) endpoints were subject to significant heterogeneity. Subgroup analyses suggested that primary technical success rates were < 80% in patients with tumors exhibiting a mean diameter ≥ 4 cm. Guidance type and tumor size had no impact on a hypertensive crisis or local recurrence rates.
CONCLUSIONS
These data indicate that image-guided RFA represents a safe and effective means of treating AMTs.

Meta-Analysis Review
INTRODUCTION
Long-term outcome of patients with adrenal incidentaloma (AI) is unknown. The aim of this study was to systematically summarize the follow-up and outcome of clinically silent AI who do not undergo surgery.
EVIDENCE ACQUISITION
All major databases and medical literature in English-language, published from 1998 to May 2015, were systematically searched for publications on AI. Primary endpoint was hormonal hyper function; secondary endpoints were time from diagnosis to study endpoint and the outcome of adrenalectomy. Meta-analysis was performed using both qualitative and quantitative approach.
EVIDENCE SYNTHESIS
A total of 11 publications were included. Total sample size was 1298 patients. Mean follow-up duration was 44.2 months. There were 82 patients confirmed to have subclinical Cushing's syndrome at diagnosis, with 1.79% new cases at the end of follow up (95% CI, 0.002 to 0.045). Incidence of Cushing's syndrome was 0.7% (95% CI, 0.001 to 0.013) and pheochromocytoma 0.4% (95% CI, 0.001 to 0.008). The mean tumor size was 2.52cm, with mean increment of 0.03cm to 2.9cm at the end of follow up. About 3% of patients ended up with surgery (95% CI, 0.01 to 0.05) but none were due to primary adrenal malignancy. Time of greatest risk of developing Cushing's syndrome and pheochromocytoma was between months 36 and 42 (hazard rate 14%), and between months 48 and 54 (hazard rate 7%) respectively.
CONCLUSIONS
Malignant change in non-functioning AI is rare. The risk of developing overt disease over the follow-up period is low. A less stringent imaging and functional work-up interval can be considered.

Meta-Analysis Review
Safety and effectiveness of minimally invasive adrenalectomy versus open adrenalectomy in patients with large adrenal tumors (≥5 cm): A meta-analysis and systematic review.
BACKGROUND
This systematic review and meta-analysis compared the safety and effectiveness of minimally invasive adrenalectomy (MIA) with open adrenalectomy (OA) in patients with large adrenal tumors (≥5 cm).
MATERIALS AND METHODS
We performed a systematic review and cumulative meta-analysis of the primary outcomes according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and AMSTAR (Assessing the methodological quality of systematic reviews) Guidelines. Five databases including Medline, PubMed, Cochrane Library, Scopus, and Web of Science were systematically searched. The time frame of the search was set from the creation of the database to March 2022.
RESULTS
Ten studies including 898 patients were included. Compared to OA, MIA is superior for length of stay [LOS WMD = -3.52, 95% CI (-4.61, -2.43), P < 0.01], drainage time [DT WMD = -0.68, 95% CI (-1.27, -0.09), P < 0.05] and fasting time [FT WMD = -0.95, 95% CI (-1.35, -0.55), P < 0.01], estimated blood loss [EBL WMD = -314.22, 95% CI (-494.76, -133.69), P < 0.01] and transfusion [WMD = -416.73, 95% CI (-703.75, -129.72), P < 0.01], while operative time (OT) and complications are not statistically different. For pheochromocytoma, MIA remains superior for LOS [WMD = -3.10, 95% CI (-4.61, -1.60), P < 0.01] and EBL [WMD = -273.65, 95% CI (-457.44, -89.86), P < 0.01], while OT and complications are not significantly different.
CONCLUSION
MIA offers advantages over OA in the management of large adrenal tumors, including in the case of a specific large adrenal tumor - large pheochromocytoma.

Meta-Analysis Review
OBJECTIVE
To evaluate the proportion of pheochromocytomas meeting the criteria for adenoma on adrenal washout CT and the diagnostic performance of adrenal washout CT for differentiating adenoma from pheochromocytoma.
METHODS
MEDLINE and EMBASE were searched to 28 March 2017. We included studies that used adrenal washout CT for characterisation of pheochromocytomas. Two independent reviewers assessed the methodological quality using Quality Assessment of Diagnostic Accuracy Studies-2. Proportions were pooled using an inverse variance method for calculating weights (random-effects). Sensitivity and specificity were pooled using hierarchical logistic regression modelling and plotted in a hierarchical summary receiver-operating-characteristics (HSROC) plot.
RESULTS
Ten studies (114 pheochromocytomas) were included. The pooled proportion of pheochromocytomas meeting the criteria for adenomas was 35 % (95 % CI 20-51). For eight studies providing information on diagnostic performance, the pooled sensitivity and specificity for differentiating adenoma from pheochromocytoma were 0.97 (95 % CI 0.93-0.99) and 0.67 (95 % CI 0.44-0.84), respectively. The area under the HSROC curve was 0.97 (95 % CI 0.95-0.98).
CONCLUSIONS
There was a non-negligible proportion of pheochromocytomas meeting the criteria for adenoma on adrenal washout CT. Although overall diagnostic performance was excellent for differentiating adenoma from pheochromocytoma, specificity was relatively low.
KEY POINTS
• Non-negligible proportion of pheochromocytomas can be mistaken for adenoma. • Adrenal washout CT showed good sensitivity (97%) but relatively low specificity (67%). • Findings other than washout percentage should be used when diagnosing pheochromocytomas.

Review
The most common pattern of esophageal cancer metastases (ECM) is to the lymph nodes, lung, liver, bones, adrenal glands, and brain. On the other hand, unexpected metastasis (UM) spread to uncommon sites has increasingly reported and consequently affected the pathway of diagnosis, staging, and management. Using the PubMed database, a systematic search of the following headings "Esophageal" and "Metastasis" or "Metastases" was performed, 10049 articles were identified, and the articles were included if they demonstrated unexpected ECM. 84% of cases were men with an average age of 60.7 years. EC was located in the lower third in 65%. Two-thirds of the UM originated from the lower esophagus, and the two major histological types were adenocarcinoma 40% and squamous cell carcinoma 60%. Metastases were disseminated toward five main anatomical sites: the head and neck (42%), thoracic (17%), abdomen and pelvis (25%), extremities (9%), and multiple skin and muscle metastases (7%). The EC metastases were found to be synchronous 42% and metachronous 58%, isolated in 53.5% and multiple in 46.5%. The overall survival rate was 10.2 months. Since distant metastases are responsible for most EC-related deaths, understanding of ECM dissemination patterns needs more extensive studies. These critical data are the cornerstone of optimal cancer approach and treatment.
