A respiratory outbreak of COVID-19 started from Wuhan, China and on 30 January 2020, WHO declared this infection to be epidemic, implementing public health emergency worldwide. On 11th March 2020, observing its prevalence in the whole world and WHO declared as a pandemic. Many countries completely collapse in the grip of this pandemic, as there are no effective treatments available, the precaution is the sole remedy to minimize this infection. The emergence and pandemic of SARS-CoV-2 (since the SARS-CoV in 2002 and MERS-CoV in 2012] manifest the third time outline of highly contagious and pathogenic infection with infect-ability to spread globally in the twentieth-first century. The SARS CoV-2 genome is highly identical to bat coronavirus which is considered to be the perfect natural host. This coronavirus even utilizes the same ACE2 receptor as SARS-CoV and mainly spread the infection to the respiratory tract, which evidently showed that transmission of this virus through interactions and exposures. The death toll of these infected patients is increasing day by day especially when they have prehistory fatal diseases like cardiovascular, diabetics, and respiratory diseases. In this review, we summarized and explained the research progressed and available data on epidemiology, COVID-19 phylogenetic relation and its impact of different fatal disease and their relation and discuss the precautionary methods to combat this pandemic. Moreover, the pieces of evidence of spreading the virus through pets and prevention of being spreading by copper metal endorsement.
Many pathologic disease can be considered as related to an Endogenous toxicological moves and in time dependent way (kinetics and dynamic of the process). In this work starting from the analysis of relevant literature involved with different disease and related to the endogenous local micro- environment some global conclusion useful as new tools for innovative pharmacological strategies will be submitted to the researcher. Physiology, pathology concept linked to the endogenous toxicological local micro-environment status as new research instruments. The same carcinogenesis process can be related also to endogenous agents that may have a major contribution in spontaneously process. (Reactive oxygen species (ROS), which are involved in multiple cellular processes by physiologically transporting signal as a second messenger or pathologically oxidizing DNA, lipids, and proteins).
Since December 2019, entire world is facing problem of corona-virus pandemics and its impact on the people and their social life has been phenomenal. Each part of the world is ‘almost’ hit by COVID-19 infection. Most of the COVID-19 victims were aged people followed by consequence of high death ratios as shown in data [1]. Not only aged people but people with some secondary diseases or disorder were of major concern. A special case comes across which are patients with intellectual disabilities (ID) are the most vulnerable group. They also have extra multiple disorders including respiratory diseases, diabetes, obesity, These individuals face more complications and stand at high risk of because, such people are usually mentally lethargic and have almost no literacy in to follow proper health care and access health facilities
Fifty years of Washington’s fixes for healthcare have brought us to the brink: insurance is unaffordable and care is unavailable, certainly not in time. The way to make healthcare work for We the Patients (all Americans) is to take healthcare authority away from third-parties – government and insurance – and restore the direct doctor-patient connection with no bureaucrat in between. The cure for patient Healthcare is StatesCare combined with market-based medicine. Financial models confirm this approach will make care both affordable and accessible in a timely manner.
We present a 54-year-old male with abdominal pain, Vomiting and weight loss since 5 months. Perforation was noted at recto-sigmoid junction and underwent Hartman’s procedure with end colostomy. Histology of sigmoid colon confirmed a Stercoral perforation without any evidence of dysplasia or malignancy. Patient had chemotherapy for squamous cell carcinoma (SCC) of epiglottis a year ago and was on codeine phosphate and Oromorph as and when required since his treatment for SCC for pain. Patient also had been suffering from constipation since he finished chemotherapy. Stercoral perforation always need to kept in mind in patients who present with constipation and need to take all patients who present with chronic constipation and initiate measures we encounter commonly in everyday practice. We present a brief review about Stercoral perforation and its management.
Sexual dimorphism exists in Homo sapiens in many systems. Lately, it was found that it also exists in autoimmune disorders. Generally, it was known that the two genders in humans have different endocrine systems, and therefore hormone hormone-regulated systems show sexual dimorphism. However, in the case of autoimmune disorders, it is not due to directly on hormonal milieu but depends on X-chromosome inactivation in males. Whereas every cell in a woman’s body produces Xist; this ribonucleoprotein contains about 81 proteins. This chromosomal inactivation in males and formation of Xist ribonucloprotein in females is responsible for sexual dimorphism in autoimmune disorders in humans.
As we know that, Asthma and chronic obstructive pulmonary diseases are well characterized diseases, they can co-exist as asthma-COPD overlap (ACO). The co-existence of asthma-chronic obstructive pulmonary disease overlap (ACO) in chronic obstructive pulmonary disease (COPD) patients is often unrecognized. In patients with a primary diagnosis of COPD or Asthma, the identification of ACO has got implication for better prognosis and treatment. Such patients experience frequent exacerbations, poor quality of life, rapid decline in lung function and high mortality than COPD or Asthma alone. Inhalational steroids provide significant alleviation of symptoms in such patients and some studies suggest that the most severe patients may respond to biological agents indicated for severe asthma. Patients who have asthma with a COPD component tend to present with severe hypoxia because of Irreversible/fixed airway obstruction and impairment of the alveolar diffusion capacity by emphysematous changes. In contrast, patients with COPD who have an asthma component not only have exertional dyspnoea but also develop paroxysmal wheezing or dyspnoea at night or in the early morning. The criteria to diagnose asthma-COPD overlap (ACO) include positive bronchodilator response, sputum eosinophilia or previous diagnosis of asthma, high IgE and/or history of atopy. There is scarcity of literature available in country like India. We highlight the importance of identification of Asthma COPD overlap as different phenotype from COPD or asthma alone as it is challenging to diagnose ACO in India. We report 3 cases having both the features of asthma and COPD, later diagnosed with Asthma-COPD overlap.
In this article different numerical techniques for solving optimal control problems is introduced, the aim of this paper is to achieve the best accuracy for the Optimal Control Problem (OCP) which has the objective of minimizing the size of tumor cells by the end of the treatment. An important aspect is considered, which is, the optimal concentrations of drugs that not affect the patient’s health significantly. To study the behavior of tumor growth, a mathematical model is used to simulate the dynamic behavior of tumors since it is difficult to prototype dynamic behavior of the tumor. A tumor-immune model with four components, namely, tumor cells, active cytotoxic T-cells (CTLs), helper T-cells, and a chemotherapeutic drug is used. Two general categories of optimal control methods which are indirect methods and direct ones based on nonlinear programming solvers and interior point algorithms are compared. Within the direct optimal control techniques, we review three different solutions techniques namely (i) multiple shooting methods, (ii) trapezoidal direct collocation method, (iii) Hermit- Simpson’s collocation method and within the indirect methods we review the Pontryagin’s Maximum principle with both collocation method and the backward forward sweep method. Results show that the direct methods achieved better control than indirect methods.
In this paper we summarise, in chronological order, all COVID-19 preventive measures undertaken by the Macau Special Administrative Region (SAR) government during the first quarter of 2020. The information and narrative contained herein may be of useful to other parts of the world in COVID-19 control and prevention, especially cities with ultra-high population densities. The four main lessons from Macau SAR are: (1) Proactive leadership and early prevention. (2) Strict adherence to community endemic control. (3) Clear prioritising of public health. (4) Planed relief for financial hardships amidst the post-pandemic recession.
Introduction: The contents of the retropharyngeal space are limited to fat and retropharyngeal nodes. Primary tumors originating from the retropharyngeal space are rare, therefore, the existence of schwannoma in the retropharyngeal space is infrequent.
Method: This paper describes a case of a large schwannoma of the retropharyngeal space excised transorally with the use of co2 laser. This lesion measured about 6/6 x 3/5.
Result: No peri-or post-operative complications were encountered. The procedure allowed quick resumption of an oral diet and a return to normal activity for the patient.
Conclusion: This is, to our knowledge, the first report of this technique used in the excision of a large retropharyngeal space schwannoma.
