Two of the most recent LABA/ICS combinations for treatment of persistent asthma are Fluticasone furoate/Vilanterol 92/22 µg (Ellipta) and Beclomethasone dipropionate/Formoterol 100/6 µg (Nexthaler).
Objective: To compare once-daily Fluticasone/ Vilanterol combination with twice daily Beclomethasone/ Formoterol association in moderate asthma, in terms of quality of life and lung function.
Methods: Fourty patients with moderate asthma treated with Beclomethasone/Formoterol 100/6 µg or Fluticasone/Vilanterol 92/22 µg. We revalued patients in terms of lung function and Asthma Control Test, at 4, 8 and 12 weeks to assess any differences between the two groups. After 4 weeks, thirty-one of the fourty patients were evaluated in terms of respiratory function at predetermined time intervals.
Result: In patients treated with beclomethasone/formoterol FEV1 presented a mean value of 78% at the third visit and of 79.1% during the final check, compared with 74.5% and to 75.8% in patients in treatment with fluticasone/vilanterol (p 0.01). Mean values of IC and MMEF25-75% were higher in patients treated with beclomethasone/formoterol compared with fluticasone/vilanterol. For the dyspnea it was a difference at the third observation. For the nocturnal symptoms and the use of rescue drug there was a significant difference, except at the beginning. For the perception of control by patients, there was a difference in the two groups at the beginning, after 4 and 8 weeks. Total ACT score showed a significant difference after 4, 8 and 12 weeks. In the group treated with beclomethasone/formoterol FEV1 value was significantly higher at a distance of four hours after drug administration (p 0.04) and after the second dose (p 0.02) compared with the group treated with fluticasone/vilanterol.
Discussion: Patients in treatment with beclomethasone/formoterol showed improved asthma control and nocturnal symptoms and more stable respiratory function compared with patients receiving fluticasone/vilanterol.
Chemotherapy is one of the main treatment options for cancer. However, chemotherapeutic agents usually suffer from poor pharmaceutical properties that restrict their use. Targeted therapy drugs have been developed to specifically target changes in cancer cells that help these cells to grow. Such drugs often work when standard chemotherapeutic drugs do not, they often have less severe side effects and they are most often used for advanced cancers. The objective of this article is to give an overview about the 16 FDA-approved targeted therapy drugs to treat non-small cell lung cancer.
Background: Diabetes mellitus is a leading cause of illness and death. Pulmonary function test PFT has assumed a key role in epidemiological studies investigating the incidence, natural history and causality of lung disease.
Methods: A cross sectional study was conducted in The National Ribat Teaching Hospital and Jabir Abualiz Specialized Diabetes Center in Khartoum state to measure the respiratory muscle power in 31 diabetic patients (case group) and 30 non-diabetics patients (control groups). Pulmonary function tests were measured by using Digital Spirometer-Micro-Plus version.
Results: Lung function parameters between diabetic patients and their matched control group show no significant differences between the means of FVC, FEV1 and FEV1/FVC. However, diabetic patients showed significant reduction in PEFR.
Conclusions: Exercise and well control of diabetes helped in preserving normal respiratory muscle power. Continuous reasonable exercise with good control is highly recommended for all diabetics.
With the invention of the stethoscope, in the early 1800s, a better diagnosis of heart and lung disorders was opened up. Through the stethoscope's 200-year history, there has been a significant development of the stethoscopy from the use of the simple monaural earpiece to the binaural stethoscope, followed by the electronic stethoscope, which, together with other studies, has enabled a thorough diagnosis of these disorders. Here is a glimpse of this story.
The cross-border investigation
Far back in time, it has been clear that the function of the heart and lungs played an important role in maintaining life. By tapping with the finger (percussion) and putting the ear to the patient's chest (auscultation), it could hear sound from the body telling about the patient's condition, especially about the presence of fluid or air-filled organs. Auscultation is already described in the Corpus Hippocraticum, in the Diseases II section [1]. The doctor puts the ear to the chest of a patient with water sores, to hear the pain as a wine vinegar from the lungs - or the doctor grabs the patient about the shoulders, shakes him and places his ear to his chest to hear in which side his pleuritis is sitting. Since then, auscultation seems to have been partially forgotten, although it has probably been known by Ambroise Paré and William Harvey [2]. It was not until the late 1700s that it became an important diagnostic aid, just like the pulse clock and the medical thermometer [3 p. 277]. Here, Joseph Leopold Auenbrugger (1722-1809) is considered to be the father of the modern physical examination, which is based on percussion. Percussion he performed by knocking direcly on the thorax with the finger or cupped hands. His discovery of the percussion sounds from the chest during inhaling and exhaling originates from his work in 1760 at the Vienna Military Hospital [4]. In 1761, His little book on thoracic percussion revealing thoracic diseases appeared in 1761 [3p.271], which in 1808 was translated into French by the Parisian physician Jean Nicolas Corvisart des Marets (1755-1821). This contributed to the French doctors starting to use percussion and ausculation more routinely [5].
The limitation of simple auscultation was the fact that the sound was weak and incomplete and therefore there was a need for improved sound quality. In addition, the direct contact with the patient's body could seem insulting

Background: In 2004 we started a phase II trial in non-small lung cancer (NSCLC), stage III, with erlotinib followed by a combination with a platinum-based doublet in unselected patients to identify molecular subgroups benefitting from an EGFR targeting approach.
Patients and methods: Induction with erlotinib (E, 150 mg, d1-42) was followed by three cycles of gemcitabine (G, 1250 mg/m², d1+d8, q3w) and cisplatin (P, 80 mg/m², d1, q3w). Patients with at least stable disease after E were treated with a GP + E combination. Induction was followed by surgery and radiation. The trial was conducted as a prospective, multi-center, open label, exploratory phase II study to determine pathological response rate (pRR), as well as secondary endpoints disease free survival (DFS) and overall survival (OS).
Results: Of 38 prescreened patients 16 were included in the main study. Due to slow recruitment the study had to be terminated early. Combination of E and GP was well tolerated, surgery was feasible after induction therapy in 12 of 16 patients, 7/12 (58%) patients had a major pathological response (MPR). Median overall survival for patients with MPR was 57.7 months (confidence interval (CI), 37.4 to 78.0; n = 7) and for patients without MPR 11.9 months (CI, 6.4 to 17.4; n = 5). 2/16 patients had an epidermal growth factor receptor (EGFR) mutation.
Conclusion: Before discovery of distinct molecular mechanisms in NSCLC our study was an attempt to identify clinical and pathological subgroups that would benefit from E induction. Two patients with an EGFR mutation were identified. MPR was a predictor of long term disease free and overall survival.
Introduction: the perennial pandemic: There are serious challenges posed by the SARS-CoV-2 virus and COVID-19 as the disease. With the persistence of the pandemic over one and half year, it is being feared that the COVID-19 may have become the new reality associated with human existence world over and the mankind may have to live with it for years or even decades. Further, the grievous nature of the disease is evolving further with genomic changes in the virus in form of mutations and evolution of variants, with enhanced infectivity and probably virulence.
Acute and chronic phases of COVID-19: Epidemiologically, it is becoming clear that apart from the advanced age and pre-existing conditions, such as diabetes, cardiovascular, pulmonary, and renal diseases, certain constituent factors render some patients more vulnerable to more severe forms of the disease. These factors influence the COVID-19 manifestations, its course, and later the convalescence period as well as the newly defined ‘Long COVID phase. The substantial continuing morbidity after resolution of the infection indicates persisting multisystem effects of ‘Long Covid’.
Lung damage associated with COVID-19: COVID-19 is primarily a respiratory disease presenting with a broad spectrum of respiratory tract involvement ranging from mild upper airway affliction to progressive life-threatening viral pneumonia and respiratory failure. It affects the respiratory system in various ways across the spectrum of disease severity, depending on age, immune status, and comorbidities. The symptoms may be mild, such as cough, shortness of breath and fevers, to severe and critical disease, including respiratory failure, shock, cytokine crisis, and multi-organ failure.
Implications for the post-COVID care: Depending on the severity of respiratory inflammation and damage, as well as associated comorbidities, duration of injury and genetics, the progressive fibrosis leads to constriction and compression of lung tissues and damage to pulmonary microvasculature. Consequently, the COVID-19 patients with moderate/severe symptoms are likely to have a significant degree of long-term reduction in lung function. Depending on the severity of the disease, extensive and long-lasting damage to the lungs can occur, which may persist after resolution of the infection.
Managing the long COVID’s challenges: Given global scale of the pandemic, the healthcare needs for patients with sequelae of COVID-19, especially in those with lung affliction are bound to increase in the near future. The challenge can be tackled by harnessing the existing healthcare infrastructure, development of scalable healthcare models and integration across various disciplines with a combination of pharmacological and non-pharmacological modalities. Following clinical and investigational assessment, the therapeutic strategy should depend on the disease manifestations, extent of damage in lungs and other organs, and associated complications.
Organizing pneumonia (OP), can be seen in association with lung injury, infection, drug intoxication, and connective tissue diseases. Patients of rheumatoid arthritis (RA) are prone to develop interstitial lung disease (ILD), but the pulmonary involvement usually occurs several years after the joint manifestations. Only in about 10% cases of RA, the initial manifestation of the disease can be in the form of interstitial lung disease. OP as the initial manifestation of RA is extremely uncommon occurrence.
Here is presented a case of 52-year-old male who presented with OP as the initial manifestation of RA. On investigation, the RA factor and anti-CCP Antibodies were positive. Based on clinical, radiological and histopathological findings the diagnosis was established.
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.
Despite the fact, that lung cancer is more common among older smoking men, however it may also develop among young women without a smoking anamnesis. We report here a history of a non-smoking woman, 40 years old, with a diagnosis of lung adenocarcinoma at IV stage. Despite the fact, the woman received three lines of palliative chemotherapy, the disease progressed. After the sample of the tumor was tested by genetic approach, ROS1 mutation was detected, and the patient was treated with a ROS1 inhibitor, Crizotinib. Sharp improvement was observed already after the first week of treatment. After one-month adenocarcinoma shrink, and specific supraclavicular lymph nodes disappeared. Unfortunately, due to problems with financing the treatment was stopped, after what the disease began to progress rapidly, and the patient died after a month due to brain metastasis. This case is noteworthy also because the patient was first diagnosed a thrombophilia with thrombi present in deep calf veins, left heart ventricle and lungs Adenocarcinoma was discovered occasionally when during video-assisted thoracoscopic surgery biopsy specimen was taken from suspicious mass in the lower lobe of the right lung. This story reminds us that lung carcinoma may start with a paraneoplastic syndrome, like thrombophilia as in this case and finding of adenocarcinoma of the lung in young, non-smoking persons is indicative for possible ROS1 gene mutation. In such cases early treatment with ROS1 protein-tyrosine kinase inhibitors should be started as soon as possible.

Pulmonary Alveolar Proteinosis (PAP) is a rare lung disease characterized by excessive accumulation of surfactant lipids and proteins in alveoli and terminal airways. It is caused by impaired GM-CSF signaling [1]. Surfactant is synthesized and secreted by alveolar type II epithelial cells, and removed by uptake and catabolism by these cells, and the alveolar macrophages. Patients with PAP usually describe gradual onset of progressive exertional dyspnea and non-productive cough. However, an asymptomatic presentation is observed in up to 25% of cases, even in the presence of diffuse radiographic changes. Three recognized subtypes exist. Autoimmune PAP is associated with neutralizing GM-CSF autoantibodies and accounts about 90% of cases. Secondary PAP may occur in the context of any disease that reduces the abundance or functionality of alveolar macrophages, resulting in impaired surfactant clearance. Congenital PAP is the result of genetic mutations that disrupt GM-CSF signaling, including mutations in the α- or β-chains of the GM-CSF receptor [1-3].
Introduction: Abdominal hernia is a pathological condition resulting from abnormal protrusion of abdominal viscera. In particular, internal hernias (IH) represents about 0.2-0.9% of all cases with para- duodenal hernias while obturator hernias accounting for only 0.07% of all hernias.
Methods: We reported the case report of 79 year old women who was admitted to Internal Medicine Department of our Hospital for lung failure and after few days transferred to our Surgery Department for abdominal pain.
Conclusion: Obturator hernia is rare type of hernia and it is more frequent in older women with history of multiple pregnancy, chronic cough, and habitual constipation. In our patients, detailed physical examination and MRI preoperative imaging studies, have induce to the successful diagnosis.
Death due to road traffic accident (RTA) was one of the leading causes of mortality and morbidity in India. In the present cross-sectional study, only the victim using two-wheelers, four-wheelers, and pedestrians were included for comparison to determine the pattern of injuries in these victims of the road traffic accident. There was a predominance of males in all three types of victims of RTA with a peak age of incidence seen in 21-30 years in two-wheeler victims, 41-50 years in four-wheeler victims, and 51-60 years in pedestrian victims. Four-wheeler (HMV/LMV) was the commonest type of offending vehicle involved in all types of victims with collision/ dash as the commonest manner of an accident. Head was the commonest region involved in pedestrian and two-wheeler victims as compared to the thorax in four-wheeler victims of accidents. Abrasion was the commonest surface injury in two-wheeler victims and pedestrians. The laceration was more common in two-wheeler victims as compared to crushed injury in pedestrian victims of road traffic accidents. The brain was the commonest organ involved in two-wheeler and pedestrian as compared to lungs in four-wheeler victims. The liver and spleen were more commonly involved in two-wheeler victims as compared to kidneys and bladder in pedestrian.
According to literature, about 90% of death from cancer is related to metastasis. Metastatic process present many similarity to some other biological processes. Once we have examined some relevant biomedical literature, by understanding the real causes of metastasis, it would become much more possible to introduce new therapeutic strategies to delay or in some cases even to stop this kind of killer process. Breast cancer, as an example, produces metastasis to different organs, which seems to be related to the subtype. We believe that a deep understanding of the roles of breast cancer cells and their interactions with the liver microenvironment in early breast cancer metastasis could be a crucial factor for the design and development of effective BCLM breast cancer liver metastases therapeutic strategies and to better understand the general process. Let’s suppose the secondary organ or organs can be considered as incubator/s for the primary metastatic cells. What kind of consequences we can have in therapy field if there is an active regulating role in determining the location of secondary cancers?
Let’s observe the role played by liver, bone marrow, CNS central nervous system, lungs, lymphocytes and other secondary locations/organs a little bit closer or maybe from a different angle let’s suppose we try to come up with just a hypothesis. Just let’s take this as a possibility, and we take the thread to see where it takes us.
Background: Cyclophosphamide is used for the treatment of malignant and non-malignant diseases, but, it induces oxidative damage and disturbance in the antioxidant defense system. Zinc oxide nanoparticles (ZnO NPs) are used in biomedical applications and consumer products. ZnO-NPs are protected cell membranes against oxidative damage, decrease free radicals and malondialdehyde (MDA) levels, and increase the antioxidant enzyme levels.
Objectives: The present aimed to evaluate the ameliorative effect of Zn-O nano-particles on oxidative damage and disturbance in the antioxidant defense system induced by cyclophosphamide in male albino rats.
Materials and Methods: 24 adult male albino rats were randomly divided into 4 groups (6 rats of each). Group I (Control group): Received 0.2 ml saline /day i.p. injection for 14 days (day by day), group II, (nZnO group): Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, Group III (CP group): Received CP (20 mg/kg/day) b.w, day by day for 14 days by intraperitoneal injection, Group IV (CP + ZnO NPs group): Received nZnO group: Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, plus CP (20 mg/kg/day) b.w., day by day for 14 days by intraperitoneal injection. After 24-hr from the last treatment, all animals were anesthetized using light ether. Blood, lungs, and liver samples were taken and prepared for biochemical measurements.
Results: Individual treatment of zinc oxide nanoparticles and CP induced liver cytochrome b5, cytochrome C reductase, and glutathione S-transferase (GST) compared to the control group, while CP increased P450. The combination of nZnO and CP prevents the elevation of cytochrome b5, P450, cytochrome C reductase, and GST compared with the CP treated group. Zinc oxide nanoparticles and CP increased liver thiobarbituric acid reactive substances (TBARS). The combination of nZnO and CP prevents the changes in TBARS concentrations compared with the CP. Injection of CP to rats reduced the activities of serum glutathione reductase (GR) and catalase (CAT) as compared with the control group. However, combination treatment of rats with nZnO and CP increased the activities of these enzymes compared with those treated with CP alone. Zinc oxide nanoparticles and CP increased serum and lung TBARS, while decreased glutathione (GSH) concentration compared to the control group, with more pronounced changes by CP. The combination of nZnO and CP prevents the changes in TBARS and GSH concentrations compared with the CP.
Conclusion: It can be concluded that CP induced oxidative stress and disturbance in the antioxidant defense system. Treatment of rats with zinc oxide nano-particles and CP together attenuated the oxidative damage and disturbance in the antioxidant defense system induced by CP. So, Patients treated with CP advised to take nZnO to prevent the side effects of chemotherapy. Further studies are necessary to evaluate the amelioration effect nZnO and other nano-particles against oxidative stress induced by CP in different doses and experimental models.
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.
Non-small cell lung cancer is one of the leading causes of cancer-related mortality worldwide. Despite recent advances in adjuvant treatments, surgical resection is basis of treatment. With the development of minimally invasive surgery in thoracic surgery, surgeons work on minimally invasive surgery for advanced stages of lung cancer, previously considered non-operable at all or previously considered non-operable with minimally invasive surgery approach.
Minimally invasive surgical techniques which are routinely used in the surgical treatment of early-stage lung cancer have started to be treated in more complicated and advanced stages of lung cancer. Bilateral anatomic resections, operations after neoadjuvant chemotherapy, bronchial sleeve lobectomies, double sleeve lobectomies, complementary pneumonectomies, and carinal sleeve resections can be performed by minimally invasive methods. The option of video-assisted surgery should be considered with oncological principles at foreground if patients have acceptable lung and cardiac performance conditions with minimal comorbidities.
This study reviews VATS experience in patients with advanced-stage lung cancer worldwide and discusses potential benefits and limitations of using VATS technology to perform thoracic surgery procedures.
Segmentectomy may be applied to all segments; superior segmentectomies (lower lobe superior segments for both lungs), lingulectomies (two segments forming lingulas of upper left lobe) and basal segmentectomies (segments other than superior segment for both lungs). In lung segment resections; segmentectomy has an equivalent morbidity, recurrence and survival rate compared to lobectomy, in patients with stage I lung cancer, tumors smaller than 2 cm and within the segmental anatomical limits. Segmentectomy also contributes more to preserving lung function and exercise capacity than lobectomy. In tumor resection; especially in patients with advanced age, insufficient performance or insufficient cardiopulmonary reserve, 2 cm in diameter and acceptable segmental margins may be provided.
Limited long-term results show oncological results of robotic approach similar to open and VATS approaches. Robotic approach facilitates surgery with more intuitive movements, greater flexibility and high definition, three-dimensional vision. However, high cost and lack of touch sense are main disadvantages of robotic surgery. New studies are needed to assess quality of life, morbidity, oncological results and cost effectiveness. However, considering development of technology in our age and fact that many surgical robot brands will be released in the near future, it is predicted that disadvantages of robotic surgery will be minimized in the near future.
This article reviews experience of segmentectomy in non-small cell lung cancer and discusses benefits and limitations of robotic segmentectomy.
Ephedra, an ancient herb, is applied to treat common cold and influenza for such a long time in China. Pseudoephedrine is a main active ingredient from Ephedra which is used for relieving nasal congestion clinically. We previously reported that pseudoephedrine showed a potent anti-inflammatory effect other than sympathomimetic effects. In the present study, we aimed to investigate whether pseudoephedrine could protect mice from the H1N1 virus infection. The mice were infected with a 20% LD50 influenza A virus (IAV) suspension via intranasal administration to establish a virus infection model. Further, the mice were orally administered pseudoephedrine or oseltamivir for 4 days from one day after infection. Our results showed that pseudoephedrine improved lung pathological damage during the IVA infection period, and it dramatically increased the survival rate and attenuated loss of body weight compared with the virus-infected control group. In addition, pseudoephedrine inhibited the cytokine storms and mRNAs expression of the TLR7 signaling pathway. Surprisingly, pseudoephedrine showed an inhibitory effect on the replication of IAV. These results give clear evidence that pseudoephedrine is a potential anti-influenza drug by blunting cytokine storms and inhibition of replication of IAV, and following these results, we speculate that it should be tested in the novel coronavirus pneumonia (COVID-19, a severe epidemic in China currently) in which the cytokine storms play a key role to damage bronchi and lung in the early stage.
COVID-19 virus structural components: The 2019-nCoV, also called SARS-CoV-2, was first reported in Wuhan, China in December 2019. The disease was named Coronavirus Disease 2019 (COVID-19) and the virus responsible for it as the COVID-19 virus, respectively, by WHO. The 2019-nCoV has a round, elliptic or pleomorphic form with a diameter of 60–140 nm. It has single-stranded RNA genome containing 29891 nucleotides, a lipid shell, and spike, envelope, membrane and hemagglutinin-esterase (HE) proteins.
Steps in progression of COVID-19 illness: Once inside the airways, the S protein on the viral surface recognizes and mediates the attachment to host ACE-2 receptors and gains access to endoplasmic reticulum. The HE protein facilitates the S protein-mediated cell entry and virus spread through the mucosa, helping the virus to attack the ACE2-bearing cells lining the airways and infecting upper as well as lower respiratory tracts. With the dying cells sloughing down and filling the airways, the virus is carried deeper into the lungs. In addition, the virus is able to infect ACE2-bearing cells in other organs, including the blood vessels, gut and kidneys. With the viral infestation, the activated immune system leads to inflammation, pyrexia and pulmonary edema. The hyperactivated immune response, called cytokine storm in extreme cases, can damage various organs apart from lungs and increases susceptibility to infectious bacteria especially in those suffering from chronic diseases.
The current therapeutics for COVID-19: At present, there is no specific antiviral treatment available for the disease. The milder cases may need no treatment. In moderate to severe cases, the clinical management includes infection prevention and control measures, and symptomatic and supportive care, including supplementary oxygen therapy. In the critically ill patients, mechanical ventilation is required for respiratory failure and hemodynamic support is imperative for managing circulatory failure and septic shock.
Conclusion: Confusion, despair and hopes: There is no vaccine for preexposure prophylaxis or postexposure management. There are no specific approved drugs for the treatment for the disease. A number of drugs approved for other conditions as well as several investigational drugs are being canned and studied in several clinical trials for their likely role in COVID-19 prophylaxis or treatment. The future seems afflicted with dormant therapeutic options as well as faux Espoir or false hopes. As obvious, not all clinical trials will be successful, but having so many efforts in progress, some may succeed and provide a positive solution. Right now, though, confusion and despair prevail.
