Combining Passive Sampling and Dosing to Unravel the Contribution of Hydrophobic Organic Contaminants to Sediment Ecotoxicity.

Contaminated sediments are ubiquitous repositories of pollutants and cause substantial environmental risks. Results of sediment bioassays remain difficult to interpret, however, as observed effects may be caused by a variety of (un)known stressors. This study aimed therefore to isolate the effects of hydrophobic organic contaminants from other (non)chemical stressors present in contaminated sediments, by employing a newly developed passive sampling-passive dosing (PSPD) test. The results showed that equilibrium partitioning between pesticides or polyaromatic hydrocarbons (PAHs) in contaminated sediments and a silicone rubber (SR) passive sampler was achieved after 1-3 days. Chlorpyrifos concentrations in pore water of spiked sediment matched very well with concentrations released from the SR into an aqueous test medium, showing that SR can serve as a passive dosing device. Subjecting the 96 h PSPD laboratory bioassay with nonbiting midge (Chironomus riparius) larvae to field-collected sediments showed that at two locations, concentrations of the hydrophobic organic contaminant mixtures were high enough to affect the test organisms. In conclusion, the developed PSPD test was able to isolate the effects of hydrophobic organic contaminants and provides a promising simplified building block for a suite of PSPD tests that after further validation could be used to unravel the contribution of hydrophobic organic chemicals to sediment ecotoxicity.

Clinical insights and real-time PCR analysis of the first adeno-enterovirus conjunctivitis outbreak in India: A comprehensive cross-sectional study.

OBJECTIVE: This cross-sectional study aimed to investigate the emergence of adeno-enterovirus conjunctivitis, with a focus on its clinical manifestations, prevalence, and implications within the context of acute epidemic conjunctivitis. METHODS: Real-time PCR analysis was employed to precisely identify the viral strain in conjunctival swab samples. A total of 80 patients were tested, and specific clinical symptoms were assessed. RESULTS: The study revealed the first documented case in India and the second worldwide of adeno-enterovirus conjunctivitis. The prevalence among the tested patients was significant, with 15% testing positive. Those infected with adeno-enterovirus exhibited shorter illnesses (≤3 days). Notably, clinical symptoms such as subconjunctival hemorrhage, chemosis, swelling, photophobia, and epiphora were significantly linked to this viral variant. Multivariable logistic regression analysis highlighted swelling and photophobia as robust predictors for identifying adeno-enterovirus conjunctivitis cases. CONCLUSION: The findings underscore the urgent need to recognize adeno-enterovirus conjunctivitis as a potential threat, capable of causing significant ocular morbidity. Swelling and photophobia emerged as robust predictors for identifying cases, emphasizing the importance of vigilant monitoring and comprehension of this viral variant. Proactive measures are essential to address its clinical implications and mitigate its impact on affected populations. Ongoing research is crucial to unravel the complete spectrum of adeno-enterovirus conjunctivitis and guide effective management strategies.

Mitochondrial cytochrome oxidase C subunit III (cox3) gene as a sensitive and specific target for molecular detection of Babesia gibsoni infection in dogs.

A PCR targeting mitochondrial cytochrome oxidase subunit III (cox3) for molecular detection of Babesia gibsoni infection in dogs has been developed in this study. Fifty blood samples from suspected clinical cases from dogs, brought to the veterinary college clinics, were examined for presence of B. gibsoni using conventional diagnosis by microscopic examination of Giemsa stained thin blood smears. In addition, species specific PCRs targeting ITS-1 region (BgITS-1 PCR) and nested PCR targeting 18S ribosomal RNA gene (Bg18SnPCR) were carried out. A 634 bp PCR fragment of B. gibsoni cox3 gene was amplified in positive samples from three geographical locations of Satara, Wai and Pune in Maharashtra state of India. From analysis of the sequence of the B. gibsoni cox3 gene, we found that the Indian isolate had 96-98% similarity to the isolate from Japan and China. Post sequencing, de-novo diagnostic primer pair for species specific amplification of 164 bp fragment of B. gibsonicox3 was designed and the PCR was standardized. The diagnostic results of de-novo Bgcox3 PCR were compared with BgITS-1 PCR and Bg18S nPCR. Thin blood smears detected 22% (11/50) samples positive for small form of Babesia species. The BgITS-1 PCR detected 25% samples (15/50) as positive and Bg18S nPCR detected 80% (40/50) B. gibsoni positive samples. The de-novo Bgcox3 PCR detected 66% (33/50) samples positive for B. gibsoni (at 95% CI). The analytical sensitivity of cox3 PCR was evaluated as 0.000003% parasitaemia or 09 parasites in 100  µl of blood. The de-novo diagnostic cox3 PCR did not cross react with control positive DNA from other haemoprotozoa and rickettsia like B. vogeli, Hepatozoon canis, Trypanosoma evansi, Ehrlichia canis and Anaplasma platys. Statistically, cox3 PCR had better diagnostic efficiency than ITS-1 PCR in terms of sensitivity (p = 0.0006). No statistically significant difference between results of cox3 PCR and 18S nPCR was observed (p = 0.1760). Kappa values estimated for each test pair showed fair to moderate agreement between the observations. Specificity of Bgcox3 PCR was 100% when compared with microscopy or BgITS-1 PCR. Sensitivity of Bgcox3 PCR was 100% when compared with that of Bg18S nPCR.

A molecular technique to explore the relationship between Porphyromonas gingivalis and severity of chronic periodontitis: A clinical approach.

Relationship between clinical severities of periodontal disease and the expression of the associated pathogens serve as good indicators of real time disease activity and progression. A double blind study using Image J software carried out to assess the density of the amplified band for Porphyromonas gingivalis in periodontally healthy and disease subjects. Results on image densities of P. gingivalis showed a statistical significance (p < 0.005) between healthy and diseased subjects and also within the various groups of periodontal disease severity. Thus, assessment of relative gel image density can be a simple yet valuable tool to monitor real time periodontal disease activity.

A clinical case concerning an extraordinary maxillary second molar having two separate palatal roots.

Key Clinical Message: Main objective of root canal therapy is to locate all the canals, cleaning and shaping, and obturation to obtain fluid tight seal. Failure to locate all canals can lead to the failure of root canal therapy. Abstract: Variation of pulp aperture, among teeth with multiple roots, constitutes recurring issue during diagnosing and completing efficient endodontic procedures. Understanding normal anatomy features and associated likely modifications is critical in the effective execution of the dental procedure, since the inability to effectively treat simply one canal may end up into endodontic unsuccessful therapy. The paper covers a procedure whereby the root pattern and canals of the maxillary second molar were modified employing an operative microscope and verified with cone-beam computed tomography (CBCT). Cone-beam computed tomography revealed that the maxillary second molar containing two different palatal roots and canals and two distinct buccal roots and canals. This Research paper presents and investigates the morphological difference observed on the maxillary second molar in order to guarantee the effectiveness of root canal treatment examined utilizing imaging techniques like CBCT.

Root canal therapy used in conjunction with follow-ups for the nonsurgical handling of an enormous periapical lesion of endodontic origin: Clinical case record.

Key Clinical Message: The main objective of root canal therapy is to locate all the canals, cleaning, and shaping, and obturation to obtain fluid tight seal and to heal the periapical lesion if present. Abstract: The proper cleaning, shaping, and disinfection of the pulp chambers, as well as the filling of the canals, are critical to the efficacy of treatment with root canals. The success of an endodontically treated tooth is dependent on the accuracy of the diagnosis, disinfection, cleaning and shaping, obturation, and finally, the prosthetic rehabilitation management. Root canal therapy should provide a hermatic as well as fluid impenetrable seal which prevents the progression of periapical infection. There are two ways to treat such lesions: surgical and nonsurgical methods. If the root canal is cleaned, shaped, and sealed properly and adequately without the use of a surgical procedure, these lesions will recover during nonsurgical root canal therapy. This case series focuses primarily on the nonsurgical treatment of an enormous periapical lesion and provides evidence that these lesions respond well without surgery.

Bridging, Mapping, and Addressing Research Gaps in Health Sciences: The Naqvi-Gabr Research Gap Framework.

Innovations pertaining to the ever-evolving needs of the medical and healthcare sciences remain constant. This creates a gap between the rationalized needs of the study and the proposed research question. However, classifying, identifying, and addressing these research gaps require a systematic and precise structured map. Using the Medical Subject Heading (MeSH) terms "Research Gaps" AND "Healthcare" AND "Framework" in MEDLINE, Scopus, and CINAHL databases with the filters yielded no relevant literature. Therefore, this review aims to fill this practical and clinical knowledge gap by developing the Naqvi-Gabr Research Gap Framework through critical synthesis based on extensive research on medical and healthcare research gaps. Fourteen research gaps are distributed for allocation as per the healthcare delivery system approach: developing new treatments or prevention strategies, improving diagnostic tools and techniques, addressing health disparities, and improving access to healthcare services. This structured framework determines the strategic mapping of research gaps corresponding to the nature of the research. The identification and classification of the appropriate research gap led to precise and concise conclusions corresponding to the research process proposed in this study. Hence, the Naqvi-Gabr Research Gap Framework is a valuable tool for determining the potential application of gaps by researchers, policymakers, and other stakeholders with a productive address.

Single-cell analysis of chromatin and expression reveals age- and sex-associated alterations in the human heart.

Sex differences and age-related changes in the human heart at the tissue, cell, and molecular level have been well-documented and many may be relevant for cardiovascular disease. However, how molecular programs within individual cell types vary across individuals by age and sex remains poorly characterized. To better understand this variation, we performed single-nucleus combinatorial indexing (sci) ATAC- and RNA-Seq in human heart samples from nine donors. We identify hundreds of differentially expressed genes by age and sex and find epigenetic signatures of variation in ATAC-Seq data in this discovery cohort. We then scale up our single-cell RNA-Seq analysis by combining our data with five recently published single nucleus RNA-Seq datasets of healthy adult hearts. We find variation such as metabolic alterations by sex and immune changes by age in differential expression tests, as well as alterations in abundance of cardiomyocytes by sex and neurons with age. In addition, we compare our adult-derived ATAC-Seq profiles to analogous fetal cell types to identify putative developmental-stage-specific regulatory factors. Finally, we train predictive models of cell-type-specific RNA expression levels utilizing ATAC-Seq profiles to link distal regulatory sequences to promoters, quantifying the predictive value of a simple TF-to-expression regulatory grammar and identifying cell-type-specific TFs. Our analysis represents the largest single-cell analysis of cardiac variation by age and sex to date and provides a resource for further study of healthy cardiac variation and transcriptional regulation at single-cell resolution.

Pharmacological Prospects of Morin Conjugated Selenium Nanoparticles-Evaluation of Antimicrobial, Antioxidant, Thrombolytic, and Anticancer Activities.

Abstract: Selenium nanoparticles (SeNPs) have gained wide importance in the scientific community and have emerged as an optimistic therapeutic carrier agent for targeted drug delivery. In the present study, the effectiveness of nano selenium conjugated with Morin (Ba-SeNp-Mo) produced from endophytic bacteria Bacillus endophyticus reported in our earlier research was tested against various Gram-positive, Gram-negative bacterial pathogens and fungal pathogens that showed good zone of inhibition against all selected pathogens. Antioxidant activities of these NPs were studied by 1, 1-diphenyl-2- picrylhydrazyl (DPPH), 2,2'-Azino-bis-3-ethylbenzothiozoline-6-sulfonic acid (ABTS), hydrogen peroxide (H2O2), superoxide (O2-), and nitric oxide (NO) radical scavenging assays that exhibited dose-dependent free radical scavenging activity with IC50 values 6.92 ± 1.0, 16.85 ± 1.39, 31.60 ± 1.36, 18.87 ± 1.46, and 6.95 ± 1.27 µg/mL. The efficiency of DNA cleavage and thrombolytic activity of Ba-SeNp-Mo were also studied. The antiproliferative effect of Ba-SeNp-Mo was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in COLON-26 cell lines that resulted in IC50 value of 63.11 µg/mL. Further increased intracellular reactive oxygen species (ROS) levels up to 2.03 and significant early, late and necrotic cells were also observed in AO/EtBr assay. CASPASE 3 expression was upregulated to 1.22 (40 µg/mL) and 1.85 (80 µg/mL) fold. Thus, the current investigation suggested that the Ba-SeNp-Mo has offered remarkable pharmacological activity.

Does Smartphone Use Really Impact Cervical Rotation and Cervical Proprioception in Asymptomatic Individuals?

Background and objective Smartphone use has increased exponentially over the last two years worldwide. The outbreak of the coronavirus disease 2019 (COVID-19) pandemic led to significantly higher dependence on the smartphone for information exchange and communication among the general public. Currently, India has hundreds of millions of smartphone users, and their numbers are on the rise. This has raised concerns regarding the adverse effects of smartphone use on mental and musculoskeletal health. In light of this, this study aimed to determine and evaluate the musculoskeletal consequences of smartphone use. Method A total of 102 participants (50 adolescents and 52 adults) who were smartphone users and are asymptomatic for cervical spine-related disorders were included based on convenience sampling. The components assessed were cervical rotation using tape measurement and cervical proprioception using the head repositioning accuracy test. Frequency distribution tables and text were used to report the results. Results The results of this research indicated reduced cervical rotation range and cervical proprioception deficits in both adolescent and adult smartphone users. Furthermore, no correlation was found between cervical rotation (right and left) and cervical proprioception (right and left rotation). Conclusion Though the results showed that both the individual components - cervical rotation and cervical proprioception - were significantly affected, there was no correlation between the components, which indicates that these asymptomatic individuals who are marginally excessive smartphone users are at increased risk for reduced cervical mobility and deficits in cervical proprioception.

Computational Search for Potential COVID-19 Drugs from Ayurvedic Medicinal Plants to Identify Potential Inhibitors against SARS-CoV-2 Targets.

BACKGROUND: To date, very few small drug molecules are used for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has been discovered since the epidemic commenced in November 2019. SARS-CoV-2 RdRp and spike protein are essential targets for drug development amidst whole variants of coronaviruses. OBJECTIVE: This study aims to discover and recognize the most effective and promising small molecules against SARS-CoV-2 RNA-dependent RNA polymerase (RdRp) and spike protein targets through molecular docking screening of 39 phytochemicals from five different Ayurveda medicinal plants. METHODS: The phytochemicals were downloaded from PubChem, and SARS-CoV-2 RdRp and spike protein were taken from the protein data bank. The molecular interactions, binding energy, and ADMET properties were analyzed. RESULTS: Molecular docking analysis identified some phytochemicals, oleanolic acid, friedelin, serratagenic acid, uncinatone, clemaphenol A, sennosides B, trilobine and isotrilobine from ayurvedic medicinal plants possessing greater affinity against SARS-CoV-2-RdRp and spike protein targets. Two molecules, namely oleanolic acid and sennosides B, with low binding energies, were the most promising. Furthermore, based on the docking score, we carried out MD simulations for the oleanolic acid and sennosides B-protein complexes. CONCLUSION: Molecular ADMET profile estimation showed that the docked phytochemicals were safe. The present study suggested that active phytochemicals from medicinal plants could inhibit RdRp and spike protein of SARS-CoV-2.

Pharmacophore modelling-based drug repurposing approaches for monkeypox therapeutics.

Monkeypox is a zoonotic viral disease that mainly affects tropical rainforest regions of central and west Africa, with sporadic exportations to other places. Since there is no cure, treating monkeypox with an antiviral drug developed for smallpox is currently acceptable. Our study mainly focused on finding new therapeutics to target monkeypox from existing compounds or medications. It is a successful method for discovering or developing medicinal compounds with novel pharmacological or therapeutic applications. In this study, homology modelling developed the Monkeypox VarTMPK (IMNR) structure. Ligand-based pharmacophore was generated using the best docking pose of standard ticovirimat. Further, molecular docking analysis showed compounds, tetrahydroxycurcumin, procyanidin, rutin, vicenin-2, kaempferol 3-(6''-malonylglucoside) were the top five binding energy compounds against VarTMPK (1MNR). Furthermore, we carried out MD simulations for 100 ns for the six compounds, including reference based on the binding energies and interactions. MD studies revealed that as ticovirimat interacted with residues Lys17, Ser18, and Arg45, all the above five compounds interacted with the same amino acids at the active site during docking and simulation studies. Among all the compounds, ZINC4649679 (Tetrahydroxycurcumin) was shown to have the highest binding energy -9.7 kcal/mol and also observed stable protein-ligand complex during MD studies. ADMET profile estimation showed that the docked phytochemicals were safe. However, further biological assessment through a wet lab is essential to measure the efficacy and safety of the compounds.Communicated by Ramaswamy H. Sarma.

In Silico Screening of Some Active Phytochemicals to Identify Promising Inhibitors Against SARS-CoV-2 Targets.

BACKGROUND: There are very few small-molecule drug candidates developed against SARS-CoV-2 that have been revealed since the epidemic began in November 2019. The typical medicinal chemistry discovery approach requires more than a decade of the year of painstaking research and development and a significant financial guarantee, which is not feasible in the challenge of the current epidemic. OBJECTIVE: This current study proposes to find and identify the most effective and promising phytomolecules against SARS-CoV-2 in six essential proteins (3CL protease, Main protease, Papain- Like protease, N-protein RNA binding domain, RNA-dependent RNA polymerase, and Spike receptor binding domain target through in silico screening of 63 phytomolecules from six different Ayurveda medicinal plants. METHODS: The phytomolecules and SARS-CoV-2 proteins were taken from public domain databases such as PubChem and RCSB Protein Data Bank. For in silico screening, the molecular interactions, binding energy, and ADMET properties were investigated. RESULTS: The structure-based molecular docking reveals some molecules' greater affinity towards the target than the co-crystal ligand. Our results show that tannic acid, cyanidin-3-rutinoside, zeaxanthin, and carbolactone are phytomolecules capable of inhibiting SARS-CoV-2 target proteins in the least energy conformations. Tannic acid had the least binding energy of -8.8 kcal/mol, which is better than the binding energy of its corresponding co-crystal ligand (-7.5 kcal/mol) against 3 CL protease. Also, it has shown the least binding energy of -9.9 kcal/mol with a more significant number of conventional hydrogen bond interactions against the RdRp target. Cyanidin-3-rutinoside showed binding energy values of -8.8 and -7.6 kcal/mol against Main protease and Papain-like protease, respectively. Zeaxanthin was the top candidate in the N protein RBD with a binding score of - 8.4 kcal/mol, which is slightly better when compared to a co-crystal ligand (-8.2 kcal/mol). In the spike, carbolactone was the suitable candidate with the binding energy of -7.2 kcal/mol and formed a conventional hydrogen bond and two hydrophobic interactions. The best binding affinity-scored phytomolecules were selected for the MD simulations studies. CONCLUSION: The present in silico screening study suggested that active phytomolecules from medicinal plants could inhibit SARS-CoV-2 targets. The elite docked compounds with drug-like properties have a harmless ADMET profile, which may help to develop promising COVID-19 inhibitors.

An In silico Investigation to Identify Promising Inhibitors for SARS-CoV-2 Mpro Target.

BACKGROUND: A limited number of small molecules against SARS-CoV-2 has been discovered since the epidemic commenced in November 2019. The conventional medicinal chemistry approach demands more than a decade of the year of laborious research and development and a substantial financial commitment, which is not achievable in the face of the current epidemic. OBJECTIVE: This study aims to discover and recognize the most effective and promising small molecules by interacting SARS-CoV-2 Mpro target through computational screening of 39 phytochemicals from five different Ayurvedic medicinal plants. METHODS: The phytochemicals were downloaded from Research Collaboratory for Structural Bioinformatics (RCSB) Protein Data Bank (PDB) PubChem, and the SARS-CoV-2 protein (PDB ID: 6LU7; Mpro) was taken from the PDB. The molecular interactions, binding energy, and ADMET properties were analyzed. RESULTS: The binding affinities were studied using a structure-based drug design of molecular docking, divulging 21 molecules possessing greater to equal affinity towards the target than the reference standard. Molecular docking analysis identified 13 phytochemicals, sennoside-B (-9.5 kcal/mol), isotrilobine (-9.4 kcal/mol), trilobine (-9.0 kcal/mol), serratagenic acid (-8.1 kcal/mol), fistulin (-8.0 kcal/mol), friedelin (-7.9 kcal/mol), oleanolic acid (-7.9 kcal/mol), uncinatone (-7.8 kcal/mol), 3,4-di- O-caffeoylquinic acid (-7.4 kcal/mol), clemaphenol A (-7.3 kcal/mol), pectolinarigenin (-7.2 kcal/mol), leucocyanidin (-7.2 kcal/mol), and 28-acetyl botulin (-7.2 kcal/mol) from ayurvedic medicinal plants phytochemicals possess greater affinity than the reference standard Molnupiravir (-7.0 kcal/mol) against SARS-CoV-2-Mpro. CONCLUSION: Two molecules, namely sennoside-B, and isotrilobine with low binding energies, were predicted as most promising. Furthermore, we carried out molecular dynamics simulations for the sennoside-B protein complexes based on the docking score. ADMET properties prediction confirmed that the selected docked phytochemicals were optimal. These compounds can be investigated further and utilized as a parent core molecule to create novel lead molecules for preventing COVID-19.

A protocol for the development of PhyCaRe: An extension of the CARE guideline for physiotherapy using the Delphi method.

Background: Case reports are one of the important forms of documentation and publication of clinical physiotherapy presenting the first line of evidence in scientific literature. In order to provide a systematic and precise structure for reporting and presenting cases, the CARE guidelines were established in 2013. However, these guidelines present limitations as while reporting require items of specific specialties following the checklist. Authors from different specialities have developed CARE extensions specifying the characteristic features of corresponding fields, however, an extension dealing with physiotherapy assessment and line of management in the CARE guidelines is proposed as PhyCaRe. Method: After consulting with the advisors, a draft will be prepared of the specific elements that should be included in the PhyCaRe using web Delphi methodology considering CARE statement as the source and SurveyMonkey will be used to undertake the web Delphi questionnaire. The web Delphi methodology will be assumed for three rounds and will be open to physiotherapists and others with substantial experience in reviewing case reports. Subsequently, an online consensus meeting, pilot testing, and submission of the CARE extension for physiotherapy will be conducted for publication. Dissemination: The 2010 "Guidance for Developers of Health Research Reporting" and instructions from the EQUATOR Network will be followed in the preparation of PhyCaRe guidelines. The guidelines will be propagated at different platforms and journals will be requested to adopt the guidelines. Registration: The reporting guideline under development is prospectively registered on the EQUATOR Network website on PhyCaRe - Reporting guideline for physiotherapy case reports.

A single-cell multi-omic atlas spanning the adult rhesus macaque brain.

Cataloging the diverse cellular architecture of the primate brain is crucial for understanding cognition, behavior, and disease in humans. Here, we generated a brain-wide single-cell multimodal molecular atlas of the rhesus macaque brain. Together, we profiled 2.58 M transcriptomes and 1.59 M epigenomes from single nuclei sampled from 30 regions across the adult brain. Cell composition differed extensively across the brain, revealing cellular signatures of region-specific functions. We also identified 1.19 M candidate regulatory elements, many previously unidentified, allowing us to explore the landscape of cis-regulatory grammar and neurological disease risk in a cell type-specific manner. Altogether, this multi-omic atlas provides an open resource for investigating the evolution of the human brain and identifying novel targets for disease interventions.

Single-cell census of human tooth development enables generation of human enamel.

Tooth enamel secreted by ameloblasts (AMs) is the hardest material in the human body, acting as a shield to protect the teeth. However, the enamel is gradually damaged or partially lost in over 90% of adults and cannot be regenerated due to a lack of ameloblasts in erupted teeth. Here, we use single-cell combinatorial indexing RNA sequencing (sci-RNA-seq) to establish a spatiotemporal single-cell census for the developing human tooth and identify regulatory mechanisms controlling the differentiation process of human ameloblasts. We identify key signaling pathways involved between the support cells and ameloblasts during fetal development and recapitulate those findings in human ameloblast in vitro differentiation from induced pluripotent stem cells (iPSCs). We furthermore develop a disease model of amelogenesis imperfecta in a three-dimensional (3D) organoid system and show AM maturation to mineralized structure in vivo. These studies pave the way for future regenerative dentistry.

Management of COVID - 19 with Siddha and Western Medicine - An Integrative Case Report.

Renaissance in acceptance of the Siddha system of medicine in all over India happened during the current scenario of coronavirus disease-2019 (COVID-19) pandemic. The classical texts of Siddha medicine contain descriptions of the symptoms of COVID-19 as a syndrome like definition that may be correlated with KabaSuram. A 49-year-old female residing at New Delhi who got COVID-19 positive with comorbidity of hypothyroidism treated successfully using an integrative treatment plan (Siddha and Allopathic) as per Government-mandated COVID-19 treatment guidelines. The patient developed symptoms such as fever, sore throat, cold, cough with expectoration, difficulty in breathing, chest congestion, and body ache. Initially the patient took Western Medicine (WM) for five days but the symptoms did not subside. After five days an integrated treatment including Siddha medicine (Internal and external medicines) initiated at In Patient ward, Safdarjung Hospital. The health of the patient improved within 3 days and all her symptoms got relieved within 10 days. After completion of treatment, she tested reverse transcription - polymerase chain reaction (RT-PCR) and it was negative on 14th day. Another patient who was admitted with her got COVID-19 positive turned negative only after 30 days as she missed the integrative medicine by probability. The reported case had a prospective follow-up for six months and found to be free of post-COVID complications. Since, this case report based on a single case which shows a positive outcome is incapable of generalizing the conclusion. Further suitable clinical trials need to be conducted to assess its efficacy. The status of the summary is reported as per CAse REport (CARE) guidelines.

Facial Laceration: A Fight Against a Bite!

Background: Facial bite injuries can cause functional, emotional, and psychological distress to the victim. Dog bites are the most commonest injuries of all mammalian bites. We as oral and maxillofacial surgeons have reported a case of 75-year-old man with a dog bite injury on his face. Step-wise management of the wound and required anti-rabies therapy has been discussed. Materials and Methods: The patient was immediately given anti-rabies prophylaxis and thorough debridement of the wound was done with various antiseptic solutions. After satisfactory debridement, margins of the wound were freshened and closure of wound was done with resorbable and non-resorbable sutures. Post-operatively, the patient was put on antibiotic regimen. Results: Not only esthetic but also functionally acceptable results were achieved. Locally applied antiseptic solutions and anti-rabies prophylaxis proved its efficacy in infection control. Conclusion: Each bite injury will have different treatment outcomes. Hereby we discuss one of the methods in the management of facial dog bite with most easily available medicaments.
