Cardiomyopathies - The special entity of myocarditis and inflammatory cardiomyopathy

Published on: 1st July, 2019

OCLC Number/Unique Identifier: 8192807959

Cardiomyopathy is a heart muscle disease with structural and functional myocardial abnormalities in the absence of coronary artery disease, hypertension, valvular disease, and congenital heart disease. However, it has become clear that diverse etiologies and clinical manifestations (e.g. arrhythmogenic right-ventricular cardiomyopathy/dysplasia (ARVC/D), ARVD/C, left-ventricular non-compaction cardiomyopathy (LVNC)) are responsible for the clinical picture of dilated cardiomyopathy (DCM). The American Heart Association (AHA) classification grouped cardiomyopathies into genetic, mixed and acquired forms, while the European Society of Cardiology (ESC) classification proposed the subgrouping of each major type of cardiomyopathy into familial or genetic, and nonfamilial or nongenetic, forms [1-4]. Cardiomyopathies are clinically heterogeneous diseases, and there are differences in sex, age of onset, rate of progression, risk of development of overt heart failure and likelihood of sudden death within each cardiomyopathy subtype [5]. Because of the complex etiology and clinical presentation, the diagnostic spectrum in cardiomyopathies spans the entire range of non-invasive and invasive cardiological examination techniques including genetic analysis. The exact verification of certain cardiomyopathies necessitates additional investigations. So, histological, immunohistological and molecular biological/virological investigations of endomyocardial biopsies are the gold standard to confirm the diagnosis of an inflammatory cardiomyopathy (DCMi) [6-10]. This review focuses on myocarditis and inflammatory cardiomyopathies underlying an immune-mediated process or persistent viral infection.

Prevalence and risk factors of lower urinary tract symptoms after robotic sacrocolpopexy

Published on: 5th January, 2023

Aims: To analyze the prevalence and risk factors for postoperative lower urinary tract symptoms (LUTS) in women submitted to robot-assisted sacrocolpopexy (RASC) for correction of pelvic organ prolapse (POP).Methods: A longitudinal prospective study was carried out on 51 consecutive women who underwent RASC to treat POP. We recorded preoperatively the presence of LUTS urgency, symptomatic stress urinary incontinence (SUI), and voiding difficulty. We also performed an urodynamic study prior to surgical intervention including an incontinence test for overt and occult stress urinary incontinence (with POP reduction). A transobturator suburethral sling (TOT) was implanted in patients with demonstrable urodynamic SUI (overt or occult). Patients' LUTS were reassessed at 6 months after the surgical intervention. McNemar test and the Fisher exact test were used to analyzing dependent variables and Student’s t - test for independent variables. Statistical significance was set at p ≤ 0.05.Results: Postoperative voiding difficulty and symptomatic SUI were significantly reduced. No significant differences were observed in the postoperative prevalence of urgency. The presence of preoperative urinary urgency was the only significant risk factor of postoperative urgency, whereas TOT placement was the only significative factor associated with postoperative symptomatic SUI. TOT placement in patients with occult SUI significantly reduced postoperative Symptomatic SUI.Conclusion: RASC reduces the prevalence of voiding difficulty but not urgency. Concomitant implantation of TOT in patients with preoperative urodynamic SUI (overt or occult) is useful to reduce symptomatic postoperative SUI.

Stem cell therapy in children with acute liver failure: The dream could come true

Published on: 11th January, 2021

OCLC Number/Unique Identifier: 8899340842

Acute liver failure (ALF) in children is a severe disease with a high mortality rate. The current treatment strategies are still defective, with many cases die when liver transplantation is unavailable. The current protocol of steroids therapy improved the survival rate of hepatitis A virus (HAV)-related ALF. However, there is still a high mortality for non-HAV cases. Stem cell therapy (SCT) has been tried in experimental animals with ALF and in few adult studies with acute-on-chronic liver failure. No previous trials of SCT have been tested in children with ALF. The absence of SCT application in ALF in children could be due to some issues. These could be related to safety, sources, administration route, optimum dosage, efficacy, and survival. It is proposed that could be the future therapy if these obstacles have been well studied and solved.

Cerebral arterial air embolism with anterior spinal cord syndrome after CT-guided hook-wire localization of Lung mass and pulmonary nodule

Published on: 19th March, 2021

OCLC Number/Unique Identifier: 8973613870

Systemic arterial air embolism (SAAE) is a rare but serious complication of CT-guided hook wire localization of pulmonary nodule usually with catastrophic and poor outcome. Hook wire needle localization is done pre-operatively by placing wire around or into the pulmonary nodule to provide the thoracic surgeon accurate location guidance of the target nodule for Video-Assisted Thoracoscopic Surgery (VATS) wedge resection with safety margins. Physicians should be aware of this possible complication during the procedure in order to rescue the patient promptly as it requires rapid diagnosis and management. We describe a 55-year-old male who underwent a CT-guided hook wire needle localization of left upper lobe lung cancer and left lower lobe pulmonary nodule prior to planned VATS wedge resection who developed altered mental status and bilateral lower extremities paralysis after wire placement was completed. His CT head demonstrated small air embolism in the left occipital area, confirming the diagnosis of cerebral air embolism and follow up CT and MRI of the head revealed multiple areas of brain infarction. In addition, he was diagnosed with anterior spinal cord syndrome (ACS), most likely due to anterior spinal artery ischemia from micro air embolism on the basis of clinical findings but with negative ischemic changes on MRI of the spinal cord. His mental status recovered but he remained paraplegic and transferred to inpatient rehabilitation service.

Characterization of the immune response in neuroimmune disorders in children

Published on: 20th April, 2021

OCLC Number/Unique Identifier: 9026721284

Background: A misguided auto-reactive injury is responsible for several types of central nervous system (CNS) conditions in pediatrics. We propose that, in some of these conditions, the adaptive immune system has a common cellular immune pathogenesis, driven predominantly by T cells, despite variability on the phenotypical clinical presentation. Methods: We have characterized the CD4+/CD8+ adaptive immune response (AIR) on pediatric patients presenting with clinical symptoms compatible with Neuroimmune Disorders (NID). Flow cytometry with deep immunophenotyping of T cells was performed on peripheral blood obtained during the acute clinical phase and compared to an age-matched cohort group (Co). Results: We found that pediatric patients with confirmed NID, exhibit a pattern of dysregulation of CD4+ lineages associated with autoimmune processes. Discussion: The autoimmune associated CD4+ dysregulation was associated with patients with NID, as compared to healthy controls and patients with non-autoimmune diagnoses. If we can improve our capacity for early accurate diagnosis and meaningful disease monitoring of pathogenic T cell subsets, we can both expedite disease detection and may serve as a guide to the administration of effective immunotherapeutic agents.

Cytokine Modulatory Effects of Sesamum Indicum Seeds Oil Ameliorate Mice with Experimental Autoimmune Encephalomyelitis

Published on: 30th October, 2017

OCLC Number/Unique Identifier: 7347013998

Background: Multiple sclerosis (MS) is an autoimmune disorder of the central nerve system (CNS), which affects the brain and spinal cord. Experimental autoimmune encephalomyelitis (EAE) is the most commonly applied experimental model for studying the MS. The aim of this study was to determine the effects of Sesamum indicum seeds oil on Experimental Autoimmune Encephalomyelitis (EAE) in mice. Methods: Sesame oil was administrated intraperitoneally three days before immunization. IFN-γ, IL-10, IL-17 and TGF-β levels and mRNA expression in supernatant of and within cultured mononuclear cells were assessed. Results: According to our results, sesame oil treated mice demonstrated significant disease severity reduction (P=0.01 and 0.001, respectively). Treated EAE mice also represented statistically significant delay in the onset of symptoms in comparison with control group. The average IFN-γ levels and mRNA of sesame oil treated EAE mice were less than untreated EAE group. IL-10 and TGF-β levels and mRNA did not differ significantly in sesame oil treated EAE mice in comparison to untreated EAE group. IL-17 levels and mRNA were also found to be decreased significantly in treated mice in comparison to untreated mice. Conclusions: Even thoughTH1 and TH17 cells through secretion of IFN-γ and IL-17, respectively, are involved in the pathogenesis of multiple sclerosis and EAE, but IL-10 has been shown to exhibit suppressive effects on these disorders. It can be concluded that sesame oil is able to induce TH2 and TH17-related immune responses and suppress TH1 type in EAE

Clinical profile, etiology, outcome and new-onset diabetes: A SARI case series

Published on: 28th June, 2022

Introduction: The world is currently facing the SARS-CoV-2 pandemic with evolving 2nd wave. The COVID-19 patients present most commonly with Severe Acute Respiratory Illness (SARI) in an emergency room with acute onset fever, cough, and breathlessness. However, not all SARI cases as per definition are due to COVID-19 infection, which is well proven in this case series of 113 cases of SARI. This is just the opposite of the other SARI series done in the pre-COVID-19 era. Also, no previous SARI case series data has shown significant association with Diabetes Mellitus, including new-onset diabetes thus figuring out the major Pathophysiological association of COVID-19 with glucose metabolism and has a bearing on the pathogenesis, treatment, and outcome of COVID-19 infection and perpetuity of pandemic of this magnitude. Here we raise concern for the first time about the growing association of an infectious pandemic with the lifestyle disorders which are non-communicable diseases but carry with them the potential of fertile soil for rapidly spreading epidemics.Aim and objective: To find out the etiology, clinical profile, treatment outcome, and mortality rate in different sub-groups of SARI cases in a tertiary care hospital and the incidence of new-onset Diabetes Mellitus in them and to investigate theoretically the hypothesis that maintaining normal glucose metabolism could prevent progression of a mild Flu-like illness (FLI) to a severe form of Severe Acute Respiratory Illness (SARI) and consequent complications such as Cytokine Storm Syndrome and Multi-Organ failure.Design: Retrospective, single-center case series of 113 SARI patients at a tertiary care hospital in Agra India between 1 March- 30 October 2020.Main outcome: The demographics, clinical, pathological, imaging, and treatment outcome data were collected. The SARI cases analyzed were defined as “Severe acute respiratory infections (SARIs) an acute respiratory illness of recent onset (within seven days) manifested by fever (≥38°C), cough and shortness of breath or difficulty in breathing requiring hospitalization and were sub-classified according to the primary etiology producing SARI in them. The findings were compiled and compared. Conclusion: Of the 113 patients of SARI – 32.7 %were associated with Diabetes, with 9.74% new-onset Diabetes and 26 % previously known Diabetes. This was mainly due to SARS-CoV-2 (24 Diabetics out of 52 COVID-19 cases- 46.1 %).The Average hospitalization stay of SARI cases was 10 days with a maximum in SARS-CoV-2 and a minimum stay of 5.22 days in Bacterial Pneumonia and 5.66 days in Koch’s Lungs.The death rate was maximum (4 out of 26) 15.3%. Hospitalized TB/Koch’s Lung patients who presented as SARI and 3.8% in Bacterial Pneumonia, 2.43% in SARS-CoV-2, and <1% in Sepsis.Those SARI cases who were euglycemic at the time of initial presentation recovered early and carried a good prognosis with less mortality as compared to those who were hyperglycemic on presentation. Also, those FLI cases who maintained euglycemia or did not have any other risk factor which predisposes them to stress (Diabetes, Prolonged fasting, Obesity, major organ disorder, Psychological disorder, and Cancer) did not progress to SARI as the endogenous steroid secretion and sympathetic activation did not occur, the intracellular pH levels remained in the alkaline range.10.18% of cases developed new-onset diabetes (a total of 11 cases) out of which 10 were in COVID-19. Thus 19.2% incidence of new-onset diabetes in SARS-CoV-2 and a prevalence of 26.9% in SARS-CoV-2, making total diabetes 46.1% in SARS-CoV-2, and out of all SARI cases, 26 % of patients developed pulmonary fibrosis with consequent long-term complications. In COVID-19 patients, it was seen only in diabetics SARS CoV-2 male patients, thus no death in non-diabetic females in COVID-19 in this case series.

Stress evaluation of maxillary central incisor restored with different post materials: A finite element analysis

Published on: 21st July, 2020

OCLC Number/Unique Identifier: 8639114755

Introduction: With the availability of different post systems and various studies on the strength of teeth restored with posts, the controversy as to which post systems provide better stress distribution of post and longevity of tooth has not been resolved. The purpose of this study was to compare the stress distribution of three different post materials using finite element analysis. Materials and nethod: Three dimensional finite element models of central incisor, three posts with crown were constructed on computer with software. Posts of three different materials (Ni-Cr post, Glass fiber post, and Zirconia post)with zirconia crown were virtually generated and a force of 100 N was applied at an angle of 450 on the palatal surface of the crown. Von Mises stresses were evaluated on the cervical, middle and apical third of the root. Results: The maximum stresses were seen on the cervical one-third in each post material indicating that this region is more prone to fracture in tooth restored with posts. Among the three materials tested, Ni-Cr post showed maximum stress generation followed by Zirconia post and glass fiber post. The maximum stresses generated by the posts were 11.4 MPa, 10.58 MPa and 4.11 MPa respectively. Conclusion: The less rigid post material like glass fiber post can be used in an endodontically treated anterior teeth.
