Retrosternal goiter mimicking asthma: A diagnostic challenge

Published on: 10th January, 2020

OCLC Number/Unique Identifier: 8529515341

Asthma is a chronic respiratory disease characterized by chronic airway inflammation. Common manifestations of asthma include wheezing, chest tightness, cough, shortness of breath. Diagnosis of asthma requires clinical documentation of respiratory symptoms, exacerbation of symptoms following exposure to triggers, as well as demonstration of expiratory airflow obstruction. Wheeze is a continuous sound, lasting longer than 0.25 s that is produced by oscillation of opposing airway walls [1,2]. Wheezing, although a typical symptom of asthma, can also be caused by other diseases. Apart from asthma, wheezing can be due to extra-thoracic upper airway obstruction, intrathoracic upper airway obstruction, lower airway obstruction. Benign multimodal goiter is a common disease, that rarely causes upper airway obstruction. Retrosternal goiter should be taken into account the differential diagnosis of upper airway obstruction [3]. The respiratory symptoms of a retrosternal goiter may be masked for years due to the slow growth of the goiter. Patients commonly complain of respiratory symptoms if tracheal diameter is narrowed more than 50% from the normal size. Respiratory symptoms may be suddenly precipitated by spontaneous or traumatically induced bleeding into the substernal goiter, as well as by tracheal infections [4]. Clinical management of this condition is really challenging. Diagnosis is also not straightforward, as clinical suspicion is needed. There are cases of retrosternal goiter mimicking asthma that remain undiagnosed for many years. Retrosternal goiter should be taken into account in the differential diagnosis of patients diagnosed as suffering from asthma, and presenting no improvement despite medical therapy. In addition, it should be taken into account that sudden gland enlargement due to hormonal changes might lead to life threatening upper airway obstruction with clinical picture similar to bronchial asthma attack [5]. In a recent very interesting case report, the authors present a case of a pregnant woman in the second trimester who presented with an acute airway obstruction due to the enlargement of a retrosternal goiter [3]. Goiters are the more common masses of the superior mediastinum [6,7]. Commonly, retrosternal goiter is due to the extension in the thorax of a cervical goiter. However, rarely, it may represent primary disease due to the growth of ectopic thyroid tissue. In addition, retrosternal goiter may develop in patient submitted to thyroidectomy due to cervical multinodular goiter [8]. Although retrosternal goiters are commonly asymptomatic, symptoms may include dyspnea, stridor, hoarseness, dysphagia, superior vena cava syndrome, transient ischemic attacks, cerebral edema, Horner’s syndrome, and thyrotoxicosis [4]. Diagnosis could be verified by neck and chest radiography, thorax CT and MRI. Chest radiography commonly shows a widened mediastinum with a superior mediastinal mass causing compression of the trachea as well as deviation of the trachea to the right. Mediastinal computed tomography reveals a mass that is extension of the thyroid gland. The presence of respiratory symptoms in a patient with retrosternal goiter is an indication for surgery. The majority of retrosternal goiters can be approached through a cervical approach [9,10].

Single-center experience in sutureless aortic valve implantation using two aortic valve prostheses

Published on: 22nd July, 2022

Background and aim of the study: Sutureless aortic valves are used to reduce operation time. However, the stent implantation might cause postoperative ECG alterations and a higher risk of paravalvular leakage. In literature, some cases of thrombocytopenia are described after implantation. We investigated the Sorin Perceval S Sutureless Valve and the Edwards Intuity Sutureless Valve.Material and methods: Seventy-nine patients underwent aortic valve replacement using a sutureless valve in a single center between 2015 - 2018. Thirty-seven patients received Sorin Perceval S (Group A) and 42 Edwards Intuity (Group B). Simultaneous bypass surgery was performed in 23 patients in Group A and 22 patients in Group B. We compared the groups regarding postoperative TTE and paravalvular leakage, postoperative ECG alterations, need for pacemaker implantation, postoperative platelet count, and 30-day mortalityResults: Only in Group B 2 patients had paravalvular leakage, and one was reoperated within the same hospital stay. In Group A, nine patients suffered from postoperative atrial fibrillation, and in Group B, 16 patients. Left bundle branch block (LBBB) was observed in 5 patients in Group A, and 13 patients in Group B. Two patients in Group A needed a definite pacemaker, and five patients in Group B. Tachy-Brady Syndrome and LBBB were observed more frequently in Group B as well as ECG alterations. One patient died within 30 days in Group A due to multiorgan failure. This patient was older and multimorbid compared to the average. Regarding platelet count, we saw a statistically significant decrease in both groups. There were no major bleeding complications or reoperations due to hemorrhage.Conclusion: Our data shows that sutureless aortic valve replacement is associated with new postoperative ECG alterations, which are self-limiting in most cases. Compared to the literature pacemaker implantation rate in Group B is higher.

Assessment of cardiovascular and renal functions during treatment with Desmodium adscendens therapy

Published on: 9th June, 2020

OCLC Number/Unique Identifier: 8873221073

Desmodium adscendens is a rain forest medicinal herb used in managing quite a number of medical conditions. Its efficacy in the treatment of several diseases has made it a first line herb for doctors, especially in managing all forms of spasm. It is however common knowledge that some of these medicinal herbs impact severely on the normal functioning of some vital organs of the body during their administration. The present study was carried out to assess the renal and cardiovascular performance in subjects undergoing treatment with Desmodium adscendens with a view to advising against its indiscriminate use. The parameters used for the assessment of renal functions were serum creatinine and urea concentrations and their clearance. Also, changes in electrolyte concentration of Sodium, Potassium and Chloride concentration were used to assess cardiovascular performance. The histology of the kidney and heart tissues was also done to determine if the extract has impact on the cyto-architecture of the organs. Twenty-four (24) wistar rats were used for the experiment. The rats were grouped randomly into four groups (n = 6). Group 1 served as control, and the rats in the group were given normal rat feeds and water. Group 2 served as low dose group, and rats in this group were administered with low dose of extract 300 mg/kg. Group 3 served as medium group, and rats in this group were treated with medium dose of extract, 450 mg/kg. Group 4 served as high dose group, and rats in this group were treated with high dose of extract 600 mg/kg. The extract was administered for 28 days. Result showed that the extract did not impact negatively on the normal function of the renal and cardiovascular system of the treated groups, rather it enhanced their performances. It can therefore be concluded that the extract is beneficial to renal and cardiovascular functions if used within the treatment dosage.

Influence of corneal spherical aberration, anterior chamber depth, and ocular axial length on the visual outcome with an extended depth of focus wavefront-designed intraocular lens

Published on: 8th August, 2022

Purpose: The purpose of the study was to evaluate which ocular parameters have an impact on visual results obtained after an extended depth of focus (EDF) wavefront-designed intraocular lens (IOL). Setting: The study was conducted in three Italian centers (private practice in Lucca and two ambulatory surgical centers in Pisa and in Rome) from 01/09/2014 to 30/09/2015.Design: The study population included 178 eyes of 91 patients who had cataract surgery and implantation of an EDF wavefront - designed IOL (Mini Well Ready - SIFI Med Tech S.r.l.).Methods: Preoperative and postoperative refractive corneal spherical aberration (SA), ocular axial length, or anterior chamber depth were measured.Results: The majority of patients were spectacle-independent for near, intermediate, and distance vision and no one reported disturbing halos or glare. No overall significant differences were observed when stratifying anterior chamber depth (ACD) and ocular axial length (AL) by uncorrected distance visual acuity (UCDVA); p = 0.465 and 1.000 respectively, corrected distance visual acuity (CDVA); p = uncorrected near visual acuity (UCNVA); p = 1.000 and 0.728 respectively; p = 1.000 under both parameters and halos; 1.000 under both parameters. Still, there was a statistically significant difference when stratifying SA with 5 mm only by UDVA (p = 0.040).Conclusion: These results are consistent with similar outcomes in the scientific literature as measured with tests of visual acuity, either with or without optical correction. We also demonstrated that these IOLs can be used in myopic and hyperopic eyes, although it may be useful to evaluate the preoperative corneal SA to achieve better results.

Cost-analysis comparison of clinical risk assessment with and without ROMA for the management of women with pelvic masses

Published on: 17th August, 2022

Objective: Pelvic masses can be classified as low risk (likely benign) and high risk (likely malignant) based on an initial clinical risk assessment, which involves a detailed history, physical exam, basic laboratory tests, and imaging. In recent years, the Risk of Ovarian Malignancy Algorithm (ROMA), which combines CA125, HE4 and menopausal status, has emerged as a powerful tool in the classification of pelvic masses and triage of patients to either a generalist gynecologist or a gynecologic oncologist for management. The objective of this study was to evaluate whether the use of ROMA, alone or in combination with Initial Clinical Risk Assessment (ICRA), provides cost savings compared to triage based on ICRA alone.Methods: A health-economic decision model was developed to assess clinical and cost differences associated with three different clinical pathways of risk assessment for a pelvic mass: ICRA alone, ROMA alone, or ICRA + ROMA in combination. Using previously reported accuracy rates and patient characteristics from a prospective, multicenter, blinded clinical trial, total healthcare costs were modeled for each clinical pathway using the Medicare 2020 reimbursement rates.Results: A total of 461 patients with pelvic masses were included with 10.4% ultimately diagnosed with epithelial ovarian cancer. Total healthcare costs for patients with benign disease, EOC, or low malignant potential tumors (LMP) (n = 441) triaged using ROMA alone were 3.3% lower than when triaged using ICRA alone. While lab costs increased 55% using ROMA, the use of ROMA alone resulted in a 4% decrease in laparoscopy costs and a 3.1% decrease in laparotomy costs compared with ICRA alone. Similarly, total costs associated with a combination of ICRA + ROMA were 3.9% lower than total costs associated with ICRA alone. The model also predicted a 63% reduction in repeat surgeries resulting from false negative ICRA when using ROMA to triage patients.Conclusion: Triage of women with pelvic masses using the more sensitive ROMA score lowers overall healthcare costs compared to ICRA alone. With fewer false negative results than ICRA alone, the ROMA score improves initial detection of malignancy and reduces second surgical treatments in women with pelvic masses.

Environmental Factors Affecting the Concentration of DNA in Blood and Saliva Stains: A Review

Published on: 7th May, 2024

DNA evidence has now become an essential part of forensic investigations since it offers vital information for person identification and crime resolution. However, the biological material is affected by some environmental factors which may impact the DNA in biological samples. This may affect the correctness and reliability of forensic DNA analysis. This review is related to the influence of various environmental conditions on the stability and degradation of DNA in biological stains including blood and saliva stains. The common factors that affect DNA are temperature, humidity, exposure to sunlight, and type of substrate. The information is crucial to improve forensic DNA analysis and forensic protocol optimization. The DNA stability and integrity in biological materials, such as blood and saliva stains, are indispensable for forensic DNA analysis. Environmental influences, however, significantly affect DNA concentration and may jeopardize forensic analysis. The present review explores various environmental factors for their effect on DNA stability in blood and saliva stains. While DNA degradation is slowed but not completely prevented by low temperatures, it is accelerated by high temperatures. Risks of contamination arise from the promotion of microbial growth and DNA breakdown by humidity. DNA photodamage brought on by sunlight exposure results in strand breakage and cross-linking. DNA stability is also influenced by the type of substrate used; porous surfaces, such as cloth, are better at keeping fluids than non-porous ones, such as glass. Maintaining the integrity of DNA evidence requires an understanding of these variables. The present studies will help to create sophisticated DNA preservation methods for use in forensic DNA examination. The study emphasizes the requirement of improvement in forensic DNA analysis skills, related to the preservation of DNA pieces of evidence and the possible effect of environmental factors.

Non-surgical Techniques for Combined Rheumatic Severe Aortic and Mitral Stenosis – Case Series and Brief Review of Literature

Published on: 13th May, 2024

Rheumatic heart disease persists as a significant concern in developing regions, often resulting in multivalvular heart conditions. Treatment options are limited, though percutaneous transvenous mitral commissurotomy effectively addresses rheumatic mitral stenosis. Non-surgical interventions for aortic stenosis include balloon aortic valvotomy and Transcatheter aortic valve replacement (TAVR), tailored to patient factors like age and comorbidities.We describe two cases of Rheumatic multivalvular disease which were managed non-surgical. The first case is a pioneering procedure performed on a young patient combined percutaneous transvenous mitral commissurotomy with balloon aortic valvotomy, guided by 4-dimensional transoesophageal echocardiography (4D TEE). This represents the first documented instance in medical literature, showcasing the potential of integrated interventions and advanced imaging techniques. In the second challenging case involving a heavily calcified, retrovirus, and Hepatitis B positive 55-year-old, a staged approach was adopted, involving percutaneous transvenous mitral commissurotomy followed by Transcatheter aortic valve replacement (TAVR). Despite complexities, this sequential strategy demonstrates the adaptability of transcatheter techniques in managing complex valvular pathologies. These cases highlight the evolving landscape of interventional cardiology and underscore the importance of tailored, multidisciplinary approaches in optimizing outcomes for patients with rheumatic heart disease and multivalvular involvement, especially in resource-limited settings. Further exploration and dissemination of such innovative strategies hold promise for enhancing cardiac care quality and expanding treatment options globally.
