Relationship Between Sonographic Findings, Fine Needle Aspiration, and Histopathological Findings of Post-thyroid Surgery.

BACKGROUND: Thyroid diseases can affect various bodily functions and often go unnoticed. Tools such as sonography and fine needle aspiration (FNA) puncture are necessary to diagnose diseases that require surgical intervention. These tools help identify signs of malignancy or benignity and obtain further data to guide therapeutic decisions. This study aims to validate the relationship between sonographic results, FNA, and final thyroid pathology. This research describes the level of correlation between sonographic findings and FNA, the sonographic and final pathology reports, and the FNA and final pathology reports. Additionally, this research aims to identify the most common diagnoses in the final pathology. METHODS: A retrospective descriptive observational study was carried out with a sample of 95 patients who underwent thyroid surgery at the National Institute of Diabetes, Endocrinology, and Nutrition (INDEN), Dominican Republic, in 2019 to determine whether a relationship exists between the sonography findings, FNA, and the final pathology in surgical thyroid pathologies. RESULTS: A total of 95 patients were studied. The success rate of the sonography results compared with the benign final biopsy result was 100% and 45.9% with the malignant final biopsy result. The success rate of the fine needle biopsy results was 95.9% for the benign final biopsy and 28% for the malignant final biopsy. Of the malignant final biopsy reports, 84.6% were papillary carcinomas, 7.7% were follicular carcinomas, and 7.7% were medullary carcinomas. CONCLUSIONS: The relationship between the sonographic results, FNA, and histopathological findings of surgical thyroid diseases is validated. The sonographic findings are specific for diagnosing benignity and malignancy. A fine needle biopsy is useful for diagnosing benignity, and the final biopsy is the standard for confirming both benign and malignant pathologies.

Feasibility and Safety of Flexible Bronchoscopy Performed Via Tracheal Tubes in Patients With Tracheostomies: A Retrospective, Single-Center Experience.

BACKGROUND: Flexible bronchoscopy (FB) is commonly performed to assess, diagnose, and treat patients with respiratory disease, and is typically performed via transnasal or transoral approaches. FB can be performed via tracheal tubes in patients with tracheostomies; however, the safety and technical feasibility has not been established. The present study evaluates the safety and feasibility of performing FB via tracheal tubes. MATERIALS AND METHODS: A total of 45 patients underwent 56 procedures involving FB via tracheal tubes at a single institution from November 2013 to November 2014 and were included in this retrospective case series. RESULTS: Patients had a median age of 68 years (interquartile range, 56 to 82.5), and 51% were female. Most patients had 2 comorbidities (interquartile range, 1 to 3), with the most common being hypertension, diabetes mellitus, and chronic kidney disease. Upper airway obstruction was the primary indication for bronchoscopy in 40% of patients. Fifty-three percent of patients had a Shiley tube #6, [internal cannula diameter (ICD) of 6.5 mm]; tracheal tubes in the remaining patients ranged from Shiley #4 (ICD, 5.5 mm) to Shiley #8 (ICD, 8.5 mm). One patient did not complete the procedure due to severe hypertension (intraprocedural systolic blood pressure >180 mm Hg). During FB, no patients experienced cardiorespiratory arrest, arrhythmia, bleeding, or desaturation that required resuscitation. Eleven patients had a mucus plug leading to atelectasis during bronchoscopy, and 8 of these had a postprocedural chest x-ray finding of lung reexpansion. CONCLUSION: FB via tracheal tubes is a technically feasible and safe procedure that does not compromise patient oxygenation.

Noninvasive assessment of subclinical atherosclerosis in persons with symptoms of depression.

BACKGROUND AND AIMS: Depression is a mood disorder characterized by persistent feelings of loss of interest along with a cluster of clinical symptoms. It is a significant public health concern affecting 350 million people worldwide. Depression has an association with increased risk of cardiovascular disease. The World Health Organization estimates both depression and coronary artery disease to be the two major causes of disability-adjusted life years by year 2020. Early identification of subclinical cardiovascular disease in people suffering from depression may significantly impact risk stratification of these patients. METHODS: An electronic search of MEDLINE database was carried out using PubMed and OvidSP. Subclinical atherosclerosis was identified by coronary artery calcium (CAC). A total of 24 studies were identified to be included in the review. RESULTS: In this review of twenty-four studies, we found that twelve studies identified a positive association between depression and subclinical atherosclerosis. Ten studies found no significant association between depressive symptoms and coronary calcification. Whereas, two studies showed negative association. CONCLUSIONS: There is mixed evidence assessing the relationship between depression and CAC. Depressive symptoms may represent a potentially modifiable risk factor for early prevention of cardiovascular disease especially in younger patients with moderate to severe depression.

Gastric Varices in Absence of Splenic Vein Thrombosis: A Rare Entity of Idiopathic Non-Cirrhotic Portal Hypertension.

Idiopathic non-cirrhotic portal hypertension (INCPH) is portal hypertension (PHT) without cirrhosis and other identifiable causes. Esophageal and gastric varices are seen in INCPH which are mostly asymptomatic. We present a rare case of symptomatic isolated gastric varices (IGV) in the setting of INCPH. We report a case of a 60-year-old man who presented with an acute onset of hematemesis and no identifiable history. Upon further evaluation, he was found to have non-bleeding dilated gastric varices on esophagogastroduodenoscopy (EGD) and PHT without cirrhosis. Our patient is unique because he has symptomatic IGV and INCPH.

"Black Esophagus" or Gurvits Syndrome: A Rare Complication of Diabetic Ketoacidosis.

Acute esophageal necrosis (AEN) also known as "black esophagus" or necrotizing esophagitis is a rare syndrome characterized by a striking diffuse patchy or circumferential black appearance of the esophageal mucosa that preferentially affects the distal esophagus and terminates at the gastroesophageal junction. Only 88 patients over a span of 40 years have received this diagnosis, and the prevalence of this disease ranges from 0.001 to 0.2% of cases in literature. It more commonly affects men (4 : 1 ratio) in the sixth decade of life. It is associated with a high mortality rate, approaching 32%. We report a case of AEN presenting in the setting of diabetic ketoacidosis (DKA), affecting both the proximal and distal esophagus.

Elevated gamma-glutamyl transferase is associated with subclinical inflammation independent of cardiometabolic risk factors in an asymptomatic population: a cross-sectional study.

BACKGROUND: Serum Gamma-Glutamyl Transferase (GGT), a marker of oxidative stress, has been suggested to be independently associated with cardiovascular disease (CVD) events. We examined the association of serum GGT levels with the burden of subclinical inflammation across a spectrum of metabolic conditions. METHODS: We evaluated 5,446 asymptomatic subjects (43 ± 10 years, 78 % males) who had an employer-sponsored physical between 2008 and 2010. Highly sensitivity C-reactive protein (hsCRP) was measured as a marker of underlying systemic inflammation. A linear regression of GGT quartiles with log transformed hsCRP and a multivariate logistic regression of GGT quartiles with elevated hsCRP (≥3 mg/L) were performed. RESULTS: Median GGT was 31 IU/l (IQR: 22-45 IU/l), 1025 (19 %) had hsCRP ≥ 3 mg/L. The median hsCRP increased with GGT quartiles (Q1: 0.9 mg/L, Q2: 1.1 mg/L, Q3: 1.4 mg/L, Q4: 1.6 mg/L, p < 0.001). Linear regression models showed GGT in the fourth quartile was associated with 0.45 mg/L (95 % CI 0.35, 0.54, p < 0.001) increase in log transformed hsCRP adjusting for risk factors. The Odds Ratio (OR) for an elevated hsCRP (≥3 mg/L) also increased with higher GGT quartiles; GGT Q2 1.44 (95 % CI 1.12, 1.85), GGT Q3 1.89 (95 % CI 1.45, 2.46), GGT Q4 2.22 (95 % CI 1.67, 2.95), compared to GGT Q1. The strength of association increased in the presence of and combination of metabolic conditions. CONCLUSION: In our cohort of asymptomatic individuals a higher serum GGT level was independently associated with increased burden of subclinical inflammation across metabolic states. These findings may explain GGT association with increased CVD risk.

Elevated serum uric acid is associated with vascular inflammation but not coronary artery calcification in the healthy octogenarians: the Brazilian study on healthy aging.

BACKGROUND: There is a limited data on the association between serum uric acid (SUA) and cardiovascular disease (CVD) among the very elderly population. AIMS: We evaluated the association of SUA, highly sensitive C-reactive protein (hs-CRP, a marker of vascular and systemic inflammation), and coronary artery calcification (CAC, a marker of subclinical CVD) in a cohort of Brazilian octogenarians (≥80 years) free from known clinical CVD. METHODS: 208 individuals were included and evaluated for an association between increasing tertiles of SUA, elevated hs-CRP (>3 mg/dL), the presence and burden of CAC (CAC > 0 and CAC > 400). RESULTS: The median hs-CRP was 1.9 (IQR = 1.0-3.4) mg/L and mean SUA was 5.3 (±1.4) mg/dL. The overall prevalence of elevated hs-CRP (>3 mg/dL) was 31 %. A significant increase in the prevalence of hs-CRP was noted across the higher SUA tertiles (p < 0.001) with 3.4 times the odds of having elevated hs-CRP in the highest SUA tertile (3.40; CI = 1.27-9.08). No association was noted with either the CAC presence and/or CAC burden (CAC > 0 or CAC > 400) across the increasing SUA tertiles. DISCUSSION: In the healthy octogenarians, higher SUA levels are associated with vascular inflammation (hs-CRP) but not with coronary atherosclerosis (CAC); markers for the subclinical CVD.

Lambl's Excrescence Associated with Cryptogenic Stroke: A Case Report and Literature Review.

BACKGROUND: In 1856, a Bohemian physician, Vilém Dusan Lambl, first described the presence of filiform lesions in aortic valve leaflets. Lambl's excrescences are tiny filiform strands that arise on the line of valve closure, and result from valvular wear and tear. It is a rare cause of cardioembolic stroke that can be detected by transesophageal echocardiogram. CASE REPORT: We encountered a 51-year-old, African-American woman with a history of recurrent strokes that we suspect may be the result of Lambl's excrescence. The patient was treated with dual antiplatelet therapy and was recommended to have surveillance transesophageal echocardiograms at 6 months and 1 year from the time of discharge. CONCLUSIONS: As there are no definitive guidelines for the management of patients with Lambl's excrescences, we present a review of the current medical literature and a specific case report in an attempt to provide a better strategy for managing this condition. In our case report, we focus on the management and treatment for Lambl's excrescence because no clear evidence has been published in the literature. Our review indicates that Lambl's excrescence, despite its relative scarcity, should be considered in the differential diagnosis of a patient with cryptogenic stroke.

The prevalence of the metabolically healthy obese phenotype in an aging population and its association with subclinical cardiovascular disease: The Brazilian study on healthy aging.

BACKGROUND: Current literature has elucidated a new phenotype, metabolically healthy obese (MHO), with risks of cardiovascular disease similar to that of normal weight individuals. Few studies have examined the MHO phenotype in an aging population, especially in association with subclinical CVD. RESEARCH DESIGN AND METHODS: This cross sectional study population consisted of 208 octogenarians and older. Anthropometrics, biochemical, and radiological parameters were measured to assess obesity, metabolic health (assessed by the National Cholesterol Education Program -Adult Treatment Panel (NCEP-ATP III) criteria), and subclinical measures of CVD. RESULTS: The prevalence of MHO was 13.5% (N = 28). No significant association with MHO was noted for age, coronary artery calcium score, cIMT, or hs-CRP > 3 mg/dl (p = NS). CONCLUSIONS: Our results suggest that the MHO phenotype exists in the elderly; however, subclinical CVD measures were not different in sub-group analysis suggesting traditional metabolic risk factor algorithms may not be accurate in the very elderly.

Does vitamin C intake slow the progression of gastric cancer in Helicobacter pylori-infected populations?

Vitamin C's role in the prevention of disease and malignancy has been studied over the last several decades. Vitamin C intake has been shown to have an inverse relationship with gastric cancer. Recent follow-up studies on high-risk populations suggest that ascorbic acid, the reduced form of vitamin C, protects against gastric cancer, for which H. pylori is a significant risk factor. In populations infected with H. pylori, there is a reduction in gastric juice ascorbic acid concentration. This article reviews the risk factors for gastric cancer and the role of vitamin C in prevention of the disease.
