Exploring the Potential Use of Withania somnifera in Leprosy and Lepra Reactions: A Molecular Docking Approach
IntroductionWithania somnifera (Ashwagandha) is a traditional herb that is currently commercially available for treating a variety of illnesses. By evaluating and verifying docking affinity scores, it is possible to explore the potential of the plant for treating leprosy and lepra-reaction as off-label use.
MethodsThe sitoindosides were used as ligands along with thalidomide in docking against targets, such as M. leprae, TNF-Alpha, and Interleukin-6 in order to determine the potential for inhibitory concentration and docking affinity.
ResultsAccording to the study, good binding energy values varied from -7 to -11 Kcal/mol. Sitoindoside IX had the highest binding affinity and important binding interactions, such as hydrogen bonding, when compared to Thalidomide and Sitoindoside X against all three receptors.
ConclusionThe present study confirmed that the Sitoindoside IX and X are a better fit for treating patients with leprosy. These findings are highly intriguing and suggest that this herb should be investigated further to validate these findings in leprosy.

A Case Study of Intradural Extramedullary Spinal Schwannoma and Multiple Thoracic Vertebral Haemangiomas Following COVID-19 Infection and Vaccination: Insights from MRI Imaging
More LessIntroductionSpinal schwannomas are benign intradural extramedullary tumors of Schwann cells, while hemangiomas are common benign vascular tumors found in the vertebral column.
Case RepresentationThis case study presents a 32-year-old male who developed both a spinal schwannoma and multiple thoracic vertebral haemangiomas following a COVID-19 infection and subsequent vaccination. The patient reported intermittent lumbar and thigh pain over 6-8 months. Magnetic resonance imaging (MRI) confirmed an intradural extramedullary schwannoma at the L5 vertebra and multiple thoracic haemangiomas at the T6-T7 levels. The schwannoma was surgically resected, and pathology confirmed the diagnosis. Postoperatively, the patient’s symptoms improved significantly, with no complications.
ConclusionThis case raises questions about a possible link between COVID-19 and these spinal conditions. Further research is warranted to explore the potential association between viral infection, vaccination, and tumor development.

Antioxidant Nutraceuticals: Their Adjunct Role in the Management of COVID-19 Infections and Post-COVID Syndrome
The COVID-19 epidemic in recent years has been produced by various coronavirus strains that nearly destroyed world health policies and economics. Emerging viral strains exacerbated the pandemic. Huge investments have been made in preventative vaccines to combat the disease, but the genetic instability of these viruses has hampered their usefulness. However, in addition to traditional therapeutic approaches, nutraceuticals have been considered efficacious in preventing and or treating COVID-19 and post-COVID syndrome. In this context, nutraceuticals such as vitamins or dietary supplements including multiple vitamins and minerals and propolis have been widely studied for their significant impact on viral respiratory diseases like SARS-CoV-2 and COVID-19. Some of these nutraceuticals having antioxidant, anti-inflammatory, and immune-modulatory properties have been highly recommended for use as an adjunct option to moderate the adverse effects associated with the COVID-19 pandemic. In this review, we intend to present the recent understanding and converse scientific implications for the use of nutraceutical antioxidants such as vitamins, minerals, probiotics, and polyphenols like bee propolis, in the management of viral respiratory diseases and post-COVID-19 syndrome. Future challenges and limitations regarding the use and bioavailability of these ingredients, and dose-response studies are further emphasized.

Exploration of Phytochemicals as Anti-biofilm Agents against Pathogenic Bacteria: Their Potential and Challenges
Multicellular surface-attached populations of bacteria embedded in the extracellular matrix are known as biofilms. Bacteria generally preferred to grow as biofilms. Quorum sensing (QS), detection of density of cell population through gene regulation, has been found to play an important role in the production of biofilms. Biofilm formation can increase the severity of infections that can lead to morbidity or mortality. Bacteria living within biofilms have a higher pattern of adaptive resistance to antibiotics. Antibiotic resistance is a barrier in the treatment of biofilms-induced acute to chronic infections such as post-surgery infections, surgery-associated wound infections, endocarditis, joint infections, burn-related wound infections occurred, ventilator-associated pneumonia, etc. So it is urgent to discover or find out potent new drugs in fight against infectious diseases such as biofilms-associated infections. Medicinal plants or herbs are a rich source for fighting with biofilms-mediated infections. Phytochemicals have exhibited significant effects in the prevention of biofilms formation against different bacteria that are causing infections. Purified compounds such as berberine, tetrandrine, embelin, xanthorrhizol, bakuchiol, etc., exhibited promising biofilm inhibition actions against different pathogenic bacteria. Plant extracts that contain several phytochemicals are evaluated for its biofilm’s inhibition property, and have shown significant potential in biofilm formation. Antibiofilm agents act by distinct mechanisms such as inhibiting the adherence of biofilms in a surface, preventing the biofilm formations, disrupting the matured biofilms, etc. This study is intended to reiterate about possibilities of plant extracts and purified compounds in the treatment of the prevention of bacterial biofilms-related infections.

Streptococcal Toxic Shock Syndrome (STSS) Secondary to Monoarticular Septic Arthritis Leading to Multiorgan Failure in a Patient without Underlying Comorbidities: Emphasizing Early Diagnosis and Management Strategies
Authors: Awad Chady, Chong Brandon, Samaniego Michelle, Omar Fahad and Omar AsadBackgroundStreptococcal Toxic Shock Syndrome (STSS) is a life-threatening condition caused by bacterial toxins. The STSS triad encompasses high fever, hypotensive shock, and a “sunburn-like” rash with desquamation. STSS, like Toxic Shock Syndrome (TSS), is a rare complication of streptococcal infections caused by Group A Streptococcus (GAS), Streptococcal pyogenes (S. pyogenes). Staphylococcus aureus is the most frequently isolated bacterial species associated with TSS. Risk factors for STSS include older age, skin wounds, recent viral infection with open sores, recent surgery, nasal packing, use of tampons or other devices, such as menstrual cups/contraceptive sponges/diaphragms, or any other chronic illness, like diabetes or alcohol/drug abuse. Our case presents a patient who did not have any of these risk factors.
Case PresentationA 25-year-old male was admitted to the Intensive Care Unit (ICU) after requiring intubation with mechanical ventilation and pressor support in the setting of septic shock. Septic arthritis was suspected, and blood and bone cultures were positive for S. pyogenes. Arthrocentesis of the affected knee (with fluid analysis and cytology) was positive for Streptococcal pyogenes. Infectious disease was consulted and the patient was empirically started on antibiotics. Kidney function continued to worsen, requiring hemodialysis. He no longer demonstrated brainstem reflexes, which prompted neurology consultation to rule out central nervous system dissemination.
Superantigens are pyrogenic exotoxins secreted by different strains of S. pyogenes and are responsible for the many symptoms of STSS that patients present with. Throat infections by the bacteria, leading to streptococcal pharyngitis, are mediated by toxin release and known to cause scarlet fever and, very rarely, STSS. The post-infectious non-pyogenic, non-suppurative syndromes of GAS are autoimmune in nature, which include rheumatic fever, acute glomerulonephritis, and very rarely, reactive arthritis. This cross-reactivity of antibodies with body tissue via a mechanism of molecular mimicry can follow streptococcal infections, like streptococcal pharyngitis. Renal disease can also occur after a localized skin infection, also known as streptococcal impetigo.
Despite the relationship of STSS with throat infections, there seem to be no reported cases of STSS secondary to septic arthritis in adult patients with no pertinent past medical history or other risk factors that could contribute to the condition.
ConclusionStreptococcal septic arthritis is an uncommon orthopedic emergency with high morbidity and mortality that requires emergent medical management. Septic arthritis needs to be treated with systemic antibiotics and joint aspiration, also known as arthrocentesis, which may be required more than once for complete recovery and avoidance of joint destruction. STSS is a very rare complication of streptococcal septic arthritis and monitoring of organ failure and hemodynamic instability is paramount for patient’s management and survival.

The Severity of COVID-19 in Systemic Lupus Erythematosus Patient
Authors: Kishor R. Danao, Vijayshri V. Rokde and Ujwala N. MahajanAs of early October 2020, the COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, resulted in approximately 35 million cases and one million fatalities worldwide. Systemic lupus erythematosus (SLE) is an autoimmune disease marked by the generation of pathogenic autoantibodies and a lack of tolerance to nuclear self-antigens. Hypocomplementemia, or an abnormal blood complement deficit, is a reliable predictor of infection in SLE patients. Moreover, it has been found that immunoglobulin (Ig), particularly IgG and IgM, is lowered in SLE patients, which may be a factor in their heightened susceptibility to infection. Bloodstream autoantibodies, lymphopenia, aberrant T-cells, proinflammatory cytokines, and impaired regulatory systems all lead to an immune response that is aberrant in lupus patients. SLE patients exhibit impaired CD8 T-cell responses, including abnormal phagocytosis and chemotaxis. Recent study has shown that COVID-19 infections significantly boost type I interferon responses. Patients with SLE and Covid-19 infection typically get immune-suppressing drugs viz corticosteroids, Janus kinase inhibitors (JAK), and tocilizumab, which improve their immune systems and diminution susceptible to COVID-19 infections.

Clinical and In vitro Data Shed New Light on the Therapeutic Advantages of Black Seeds (Nigella sativa) for the Treatment of Hepatitis C and Hepatitis B Viral Infections
BackgroundHepatitis C Virus (HCV) and Hepatitis B Virus (HBV) can cause acute and chronic viral infections. Due to their higher costs, potential side effects and drug interactions, and associated risks, some patients with HCV and HBV infections may not be able to afford conventional antiviral medications.
ObjectiveThe goal of this review paper is to highlight the advantages of Nigella sativa, or black seeds, in the treatment of patients with HCV and HBV infections.
MethodsMedline/Pubmed/PMC, Scopus, Web of Science, Google Scholar, Science Direct, Ebsco, Embase, and reference lists were searched to locate the research studies that assessed the effects of different black seed (N. sativa) preparations on the telltale signs and symptoms of HCV and HBV infections.
ResultsNumerous preclinical and clinical investigations have suggested that black seeds (N. sativa) may be effective against HCV and HBV infections. Furthermore, N. sativa, or black seeds, have demonstrated a range of pleiotropic effects, such as antiviral activity against multiple other viruses and anti-inflammatory, antioxidant, and immunomodulatory properties that can lessen the symptoms and indicators of HCV and HBV infections.
ConclusionPatients with HCV and HBV infections may benefit from using black seeds (N. sativa) as an adjuvant therapy in addition to conventional therapy. Additional randomized controlled clinical trials would confirm the safety and effectiveness of Nigella sativa (black seeds) in treating HCV and HBV infections.

Diagnosis of Genital Tuberculosis Unveiled by Utero-Cutaneous Fistula and Superimposed MRSA Infection: A Case Report
BackgroundBoth tuberculosis and Methicillin-Resistant Staphylococcus aureus (MRSA) are known to be notorious for causing fistulas due to their characteristics of persistent, difficult-to-treat infections that lead to chronic inflammation, abscess formation, and tissue necrosis. There are several case reports highlighting the invasiveness and potential for fistula formation associated with both tuberculosis and MRSA infections independently, but to the best of our knowledge, this is the first case of a utero-cutaneous fistula caused by chronic infection due to MRSA, superadded on genital tuberculosis.
Case PresentationA 35-year-old female, P3L3, visited the gynaecology outpatient department nine months after her last caesarean section with the complaint of severe pain and blood discharge from the transverse supra-pubic scar during menstruation. On evaluation, she was found to be chronically infected with MRSA and have genital tuberculosis only after histopathologic examination of the fistulous tract and tubo-ovarian abscess.
ConclusionThis case highlights the importance of considering genital tuberculosis in patients with atypical or refractory post-surgical complications and emphasizes the need for a thorough and multidisciplinary approach to its management.
