Related the extremely transmittable abilities of SARS-CoV-2,a harmonious virus to the bat CoV, gets transmitted by three principal processes-- the inhalation of droplets from the SARS-CoV-2 infected person, contacting to the person, and by the surfaces and materials defiled with the virus. Whereupon bat Coronavirus is mostly like the pandemic causing virus SARS-CoV-2, bats are often deliberated and figured out as a possible primary host although no intermediate has not been defined yet in the wherewithal of transmission. The Spike Glycoprotein plays an important role in the case of penetration with the assistance of the ACE2 receptor and the Receptor Binding Domain. In the human body, infiltrating the nucleic acid into host cells, SARS-CoV-2 attacks one cell and one by one into the whole human body; therefore, infected cases are found symptomatic and asymptomatic considering the immune power. Patients with cardiovascular disease or diabetes proceed with their treatment with ACE2 often; therefore, there might be a high chance of getting infected. Whereas the SARS-CoV-2 infects the blood and then lungs, Antigens improvement can be better in order to avoid high-complicated effects. Currently, no vaccination or no accurate cure and treatment has not been defined. An explanation with analysis on SARS-CoV-2 has been performed from the aspect of virology, immunology and molecular biology. Several relevant figures have been included hereby in order to a better understanding of the very concept.

Endotheliosis, thrombotic microangiopathy and complement system over activation have been described as pathologic features of tissue damage in the setting of coronavirus disease. Interestingly, complement-mediated cell injury is also a typical feature of atypical Hemolytic Uremic Syndrome. Indeed, a growing body of literature has described a higher risk of microangiopathy recurrence, in aHUS patients who test positive for SARS-CoV-2. The correct clinical and therapeutic management patients with a history of HUS and SARS-CoV-2 infection is not well established.We report a case of SARS-CoV-2 infection in an aHUS patient who did not develop a recurrence of the disease and that was successfully treated with convalescent immune plasma therapy.

In recent years polyolefin nanocomposites are of great interest because of their high potential as materials with novel properties [1,2]. The properties of the nanocomposites are not only influenced by the kind of fillers but also by the microstructure of the polyolefin, the distribution of the fillers, and the preparation process. Nanocomposites prepared by extrusion moulding of mixed polyolefin and nanoparticles show often less stability by agglomeration of the nanoparticles. A better distribution is obtained if the polymerization catalyst is absorbed on the surface of the nanoparticles. After adding an olefin a growing film of the polyolefin is covering every nanoparticle (in situ polymerization). 

Lipoma is a benign mesenchymal tumor with a thirteen percent incidence in head and neck region. Posterior triangle is the most common location while anterior neck lipoma is a rare one. Giant lipomas >10cm have been reported in different parts of the body but rarely in the anterior neck. Giant lipomas of the neck can present as a cosmetic disfigurement or can produce pressure symptoms. Most lipomas do not pose any difficulty in diagnosis. Surgical excision remains the treatment of choice. We here present a case of giant anterior neck lipoma.

Background: Pure red cell aplasia is characterized by anemia, reticulocytopenia and diminished bone marrow erythroid precursors. It has multifactorial etiology and consequently several therapeutic interventions. Case: In August 2017, a young patient was diagnosed to have pure red cell aplasia. She was given immunosuppressive therapy for approximately two months but this treatment was stopped due to intolerance. Later on she developed herpes zoster infection that was treated with valacyclovir. Subsequently, it was noted that the patient became blood transfusion independent due to normalization of her hemoglobin and regeneration of the erythroid precursors in the bone marrow. Discussion: Varicella zoster virus behaves differently from other members of the herpes group of viruses such as cytomegalovirus and Epstein-Barr virus. Two retrospective studies, performed in patients with malignant hematological disorders and bone marrow failure, have shown that infection with the virus may cause stimulation of the three cell lines in the bone marrow and superior overall survival. Conclusion: The outcome of the patient presented confirms the findings of the two studies showing long-term beneficial effects of varicella zoster virus infections in immunocompromised individuals.

Introduction: Hypertension is the leading remediable risk factor for cardiovascular disease, affecting more than 1 billion people worldwide, and is responsible for more than 10 million preventable deaths globally each year. Hypertension can be described as the ‘Sleeping snake’, which bites when it wakes up. Objectives: To detect hypertension and its associated factors among staffs of Dessie town government schools from December 10, 2018 to February 15, 2019 G.C. Methods and materials: An institution-based cross-sectional study design was conducted among 225 Dessie town government school staffs whose age of 35 years and above. Systematic random sampling technique to select sample size of participants. Data was cleaned manually, coded and entered into Epi-info and analyzed by SPSS version 22 software. Multivariable logistic analysis AOR, 95% CI and p - value < 0.05 was used to identify variables which have significant association. Results: From the total of 225 study participant’s 31(13.8%) of them diagnosed with hypertension. Multivariable logistic analyses had shown that 1st degree holders AOR (CI) = 3.05 [0.91,13.43], source of information from news AOR(CI) = 2.1 [0.816, 4.89], being protestant in religion AOR (CI) = 5.65 [0.74, 42.86], age from 41-60 years AOR (CI) = 1.96 [0.18,18.90], being divorced AOR (CI) = 2.35 [0.91,5.84], and teachers AOR (CI) = 3.4 [1.2, 9.825] maintain their significant association with detection of hypertension. Conclusion and Recommendation: From this study significant numbers of respondents have hypertension. Educational status, source of information, marital status, occupation, religion and age of respondents were predictors for the occurrence of hypertension. Newly diagnosed hypertension on this was high among government school staffs which have no information about their blood pressure; which shows there was poor coverage of health screening.

Granulomatosis with polyangiitis (GPA), a form of ANCA-associated vasculitis (AAV), is a rare disease with an often-occult presentation. It is more common in 4th and 5th decades of life but can be seen in all ages. This case report details a 76-year-old female presenting with abdominal pain, generalized weakness, and malaise, who was found to have pulmonary nodules on chest imaging. Biopsy of the lung nodule showed organizing pneumonia. Initially, antibiotics were used to treat the patient. However, she developed acute renal failure a few days after presentation and found to have positive serum C-ANCA as well as elevated ANCA-PR3 serologies. A subsequent kidney biopsy demonstrated pauci-immune necrotizing and crescentic glomerulonephritis that was consistent with GPA and the patient was started immediately on combination immunosuppressive therapy, plasmapheresis, and hemodialysis. GPA’s clinical and radiological presentation can mimic other common conditions such as pneumonia, malignancy, bacterial sinusitis, pulmonary tuberculosis, sarcoidosis, and urinary tract infection. Because of this, a high level of suspicion is required for early diagnosis and treatment to alter the high mortality rate in this disease entity. All forms of ANCA-associated vasculitis (AAV) should be in the differential diagnosis for all patients presenting with multiorgan system involvement particularly in individuals with pulmonary and renal manifesations.

The lymphatic system consists of small non-contractile lymph vessels which collect fluid from the interstitial space and carry it to the major contractile lymphatic vessels with valves that maintain a unidirectional flow to the lymph nodes and is responsible for returning proteins, lipids and water from the interstitium to the venous system near the junction of the subclavian vein and internal jugular vein on both sides. Lymphedema would be the result of the failure of transport with the further accumulation of fluid rich in protein at the interstitium, especially in limbs. Primary lymphedema, which affects 1.15 / 100000 children (especially pre-pubescent girls), not always clinically evident at birth, is a genetic disorder that represents many different subsets of phenotypes: congenital or congenital lymphangiectasia, congenital trofoedema family or Meige, congenital amniotic band and essence or idiopathic. The most common form of presentation is due to congenital absence or abnormality of the lymphatic tissue caused by a genetic mutation of the genes responsible for the development of lymphatic vessels that is characterized by the difficulty of draining lymph vessels. This genetic alteration may be sporadic or inherited.

Introduction: Aluminum Phosphide (AlP) poisoning is a life-threatening condition that commonly occurs in developing countries, often resulting in cardiac, respiratory, and metabolic complications, leading to multi-organ failure and mortality. Extracorporeal Membrane Oxygenation (ECMO) has been proposed as a potential therapy for severe AlP poisoning cases refractory to conventional management, though its use remains controversial. Methodology: for this literature review, we conducted a comprehensive analysis of existing literature concerning the utilization of ECMO in patients with severe AlP poisoning. We meticulously examined available publications to explore the relationship between ECMO initiation and patient outcomes. Discussion: The review reveals that early ECMO initiation within 6 hours of presentation is associated with better outcomes and higher survival rates in severe AlP poisoning cases. However, uncertainties persist regarding the optimal timing and duration of ECMO support, and potential complications, including bleeding, acute renal injury, and ventilator-associated pneumonia, need careful consideration. Conclusion: Despite promising results in certain cases, the risks and benefits of ECMO in AlP poisoning require meticulous evaluation. Ethical considerations, encompassing resource allocation and implications for other patients, necessitate appropriate patient selection criteria.

Background: Because of a possible risk of induction of Ventricular Fibrillation (VF) by defibrillation of atrial fibrillation (AF) postulated by LOWN and coworkers, synchronized cardioversion is used worldwide. This prospective, randomized study assessed the efficacy and safety between R-wave controlled cardioversion and defibrillation of AF at 2 study centers in Cologne, Germany. Hypothesis: Defibrillation is not significantly different from cardioversion primarily in the occurrence of VF or sustained Ventricular Tachycardia (VT) and secondarily in restoring sinus rhythm, inducing non-sustained VT, asystole, or bradycardia.Methods: 146 patients at an outpatient practice and 122 at the university hospital were randomized to cardioversion (n = 140) or defibrillation (n = 124).Results: Cardioversion was successful in 92.1% of cases and defibrillation in 87.1%. The difference in efficacy was not statistically significant. In n = 1 patients receiving defibrillation, VF occurred after the first shock (200J) and immediate defibrillation (200J) restored sinus rhythm. In the n = 1 case, asystole occurred during cardioversion which terminated spontaneously. In n = 1 patients cardioverted and n = 2 who were defibrillated, sinus bradycardia occurred requiring Atropine in two cases. There were no thromboembolic events within 10 days. N = 9 patients reverted to AF within two hours. No patients died. Conclusion: Electrical conversion of AF can be performed with similar results and low risk with both R-wave-triggered cardioversion and defibrillation. In particular, defibrillation with higher energies (> 100J) can be performed as effectively and safely without a statistically significant increased risk of VF or VT. There was no difference in efficacy and risk between electrotherapy performed in the outpatient and inpatient settings.
