Isolated Pyomyositis of the Thigh With a Sinus Tract: A Rare Presentation of Tuberculosis.

Muscular tuberculosis as a primary focal lesion in an immunocompetent individual without any underlying bone involvement is a rare finding. The authors present a case of a young female in her 30s who presented with complaints of recurrent discharging sinus in the posteromedial aspect of the proximal right thigh for eight months. The patient was treated by surgical debridement followed by antitubercular therapy (ATT) and has shown full recovery during the post-eight-month treatment period. Such a presentation of primary tubercular pyomyositis imposes a diagnostic as well as a therapeutic challenge.

Redox-Sensitive Poly(lactic-co-glycolic acid) Nanoparticles of Palbociclib: Development, Ultrasound/Photoacoustic Imaging, and Smart Breast Cancer Therapy.

Breast cancer is one of the leading causes of mortality in women globally. The efficacy of breast cancer treatments, notably chemotherapy, is hampered by inadequate localized delivery of anticancer agents to the tumor site, resulting in compromised efficacy and increased systemic toxicity. In this study, we have developed redox-sensitive poly(lactic-co-glycolic acid) (PLGA) nanoparticles for the smart delivery of palbociclib (PLB) to breast cancer. The particle size of formulated PLB@PLGA-NPs (nonredox-sensitive) and RS-PLB@PLGA-NPs (redox-sensitive) NPs were 187.1 ± 1.8 nm and 193.7 ± 1.5 nm, respectively. The zeta potentials of nonredox-sensitive and redox-sensitive NPs were +24.99 ± 2.67 mV and +9.095 ± 1.87 mV, respectively. The developed NPs were characterized for morphological and various physicochemical parameters such as SEM, TEM, XRD, DSC, TGA, XPS, etc. The % entrapment efficiency of PLB@PLGA-NPs and RS-PLB@PLGA-NPs was found to be 85.48 ± 1.29% and 87.72 ± 1.55%, respectively. RS-PLB@PLGA-NPs displayed a rapid drug release at acidic pH and a higher GSH concentration compared to PLB@PLGA-NPs. The cytotoxicity assay in MCF-7 cells suggested that PLB@PLGA-NPs and RS-PLB@PLGA-NPs were 5.24-fold and 14.53-fold higher cytotoxic compared to the free PLB, respectively. Further, the cellular uptake study demonstrated that redox-sensitive NPs had significantly higher cellular uptake compared to nonredox-sensitive NPs and free Coumarin 6 dye. Additionally, AO/EtBr assay and reactive oxygen species analysis confirmed the superior activity of RS-PLB@PLGA-NPs over PLB@PLGA-NPs and free PLB. In vivo anticancer activity in dimethyl-benz(a)anthracene-induced breast cancer rats depicted that RS-PLB@PLGA-NPs was highly effective in reducing the tumor size, hypoxic tumor, and tumor vascularity compared to PLB@PLGA-NPs and free PLB. Further, hemocompatibility study reveals that the developed NPs were nonhemolytic to human blood. Moreover, an in vivo histopathology study confirmed that both nanoparticles were safe and nontoxic to the vital organs.

Design and development of a horizontal contact separated (HCS) test setup for measuring the performance of triboelectric nanogenerator for sustainable energy harvesting applications.

Triboelectric nanogenerators (TENGs) can play a pivotal role in harnessing non-utilized reciprocating motion and convert it into electrical energy that can later be stored in a battery or capacitor to power various Internet of Things-based smart electronic and wearable devices. Herein, we designed a cost-effective instrumental test bed focused on investigating the output performance of a horizontal contact separation mode triboelectric nanogenerator by varying the input parameters, such as applied force, motor speed, triboplate separation, and frequency of instrumental setup. The test bed mainly consists of three major parts: (i) application of force, (ii) tapping of TENG sample, and (iii) output parameters measurement. The output performance in terms of open circuit output voltage (VOC), short circuit current (ISC), and power density of polydimethylsiloxane-based TENG was monitored and optimized by varying the input parameters. A low-cost current measuring circuitry using an operational amplifier integrated circuit has been proposed with 92% accuracy. The maximum value of VOC and ISC was observed to be 254 V and 31.8 µA at a motor speed of 600 rpm, the distance between both the plates was 6 mm, the input applied force of 40 N, and the striking frequency of 3 Hz. The maximum power density of 2.1 W/m2 was obtained at an input impedance of 8 kΩ. The durability of the test bed as well as the TENG sample was also measured for 25 h. The degree of uncertainty was measured for VOC, ISC, and applied force and calculated to be 1.62%, 7.45%, and 6.27%, respectively.

Social Determinants and the Prevalence of Paan Masala Use among Adults in India: Results from Global Adult Tobacco Survey, 2016-17.

BACKGROUND: Gutkha or Paan masala with tobacco is commonly used smokeless tobacco product in India. Given the restrictions on advertisement and promotion of Gutkha and the necessity of warning labels on tobacco products, the tobacco industry has popularised paan masala without tobacco as a surrogate product. Paan masala itself is harmful for health but remains beyond scope of current tobacco control policies. It was important to understand prevalence and determinants of its use (with or without tobacco). METHODS: Data from the Global Adult Tobacco Survey (GATS)-2, India was used to estimate prevalence of paan masala use (with or without tobacco) in India. Multi-nominal regression and logistic regression were used to calculate risk ratios and odds ratios. RESULTS: The prevalence of any form of paan masala was 12.1% among adults in India. Prevalence was higher among males (17.8%) than females (6.0%), aged 25-44 years (14.5%) than those aged 65 years or above (9.0%). Relative risk ratio (RRR) for Paan masala with tobacco was significantly high among those with no formal schooling (RRR:2.00) and among those in poorest wealth quintiles (RRR:1.26). While, RRR were lower for Paan masala use without tobacco among those with no formal schooling (RRR:0.95) and among poorest wealth quintiles (RRR:0.78). Region-wise AOR were highest for North-East (AOR:4.80) and Central regions (AOR:4.76) compared to South India. CONCLUSION: The prevalence of paan masala use is high in India. Persons belonging to lower socioeconomic status or having no formal schooling have higher risk of consuming paan masala with tobacco. However, persons from higher wealth quintiles or having formal schooling had higher risk of use of paan masala without tobacco. These findings need careful attention of policy makers and law enforcers as it indicates different marketing strategies might have adopted by industry to target these two mutually exclusive population groups.

Various Modalities of the Resurfacing of the Lower Limb and Its Outcome.

Introduction With a better understanding of local fasciocutaneous flaps, local muscle flaps, split skin grafts, myocutaneous flaps, cross-leg flaps, and microvascular free tissue transfers, soft tissue management has improved during the past few years. The present study was conducted to study the various modalities of resurfacing lower extremity wound defect and their clinical outcome in patients with lower extremities trauma. Methodology An observational study was done in the Department of Plastic Surgery at Baba Raghav Das (BRD) Medical College, Gorakhpur (UP), and Maharshi Vashishtha Autonomous State (MVAS) Medical College, Basti (UP), with 30 patients admitted for lower limb resurfacing irrespective of the cause of wound defect from December 2020 to November 2021. Age, comorbidities, wound features, surgical techniques, postoperative outcomes, and complications were all recorded from the patients' case sheets. Results All 30 patients in our study underwent some or other form of soft tissue cover suturing or healing with secondary intention or skin graft or flap cover. The majority of the patients underwent debridement and skin graft (70.0%). Flaps were used in the exposed tibia/joint/flexor surface of the limb. The donor area in all the cases was skin grafted. Conclusion Trauma and burns are the most common causes of soft tissue defects in the lower extremity. The major goal of the patient's treatment is to achieve rapid functional results and lesser cosmetic restoration, while using the least-invasive treatment procedure possible. The use of free flap is decreasing, while the use of local flap is increasing. However, it should be kept in mind that some procedures used to preserve function may not have the best long-term effects, and, in some instances, amputation may be required.

A Comparative Study of Solifenacin, Mirabegron, and Their Combination as Bladder Relaxants in the Management of Overactive Bladder.

Introduction  Overactive bladder (OAB) is a medical state that presents as the urgency of urine and increased frequency of micturition and is diagnosed on the basis of the presence of these symptoms in the absence of other explainable diagnoses. The management of this condition includes conservative management, medical management/pharmacotherapy, and surgical management. The overactive bladder has been treated with smooth muscle relaxants, but there are conflicting results. Hence, this study aimed to assess the result of the two smooth muscle relaxants, mirabegron and solifenacin, and their combination to manage an overactive bladder. Methodology  A clinical trial was conducted at Swaroop Rani Nehru Hospital, Motilal Nehru Medical College, Prayagraj, India, over the period from November 2019 to December 2020. Ninety patients with OAB were divided into three groups: G1, G2, and G3. These groups were administered solifenacin, mirabegron, and a combination of mirabegron and solifenacin (S+M), respectively. Follow-ups were conducted at 2, 4, 12, and 18 weeks for evaluation. Data were entered into IBM SPSS Statistics for Windows, Version 23 (Released 2015; IBM Corp., Armonk, New York, United States). Appropriate statistical tests, including the chi-square and ANOVA, were employed in this study. Observation  The combination of mirabegron and solifenacin was significantly more effective in terms of response compared to solifenacin alone. There was no significant difference between solifenacin versus mirabegron, or between mirabegron (M) and the combination of mirabegron (M) and solifenacin (S). Side effects were more severe in patients taking high doses of solifenacin. Conclusion  The S + M combination has higher efficacy than solifenacin and mirabegron when given alone.

A Prospective Observational Study on the Outcome Assessment of Conservative Management Versus Intercostal Drainage (ICD) in Blunt Chest Injury Patients With ≤3 Rib Fractures in a North Indian Tertiary Care Center.

Introduction Trauma is the third most common cause of death in all age groups. One out of four trauma patients die due to thoracic injury or its complications. Seventy percent of thoracic traumas are due to blunt injury. This indicates the importance of chest trauma among all traumas. Quick and precise assessment bears paramount importance in deciding life-saving and definitive management. Often, the initial management in blunt injury patients is based on subjective assessment by the attending clinician. A scoring system that provides early identification of the patients at the greatest risk for respiratory failure and more likely to require mechanical ventilation and require prolonged care, as well as those with a higher mortality risk, may allow the early institution of intervention to improve outcomes. Thoracic Trauma Severity Score (TTSS) poses to be a precise tool in directing the management modality to be employed. Methodology This was an observational study including 112 patients of age >12 years, with blunt chest injury, sustaining ≤3 rib fractures, and with a stable chest wall. The patients with penetrating injury, those with blunt chest injury having flail segment, patients in the pediatric age group (<12 years), or polytrauma patients were excluded from our study. Of the 112 patients, 56 had been managed by intercostal drainage (ICD), and the rest (56) had been managed conservatively. Result Road traffic accidents (RTA) were the most common mode of injury in both groups. The percentage of the patients with one, two, and three rib fractures was 57.14%, 32.14%, and 10.71%, respectively, in the ICD group and 85.71%, 7.14%, and 7.14%, respectively, in the conservative management group (p = 0.124). The mean TTSS score was significantly more in the ICD group as compared to the conservative management group in the single rib fracture patients (p = 0.001*), as well as all patients of any number of rib fractures (p < 0.01*) (significance was defined as a value of p less than 0.05 {indicated by an asterisk}). The mean hospital stay was significantly lower in the conservative group as compared to the ICD group (p < 0.01*). The mean SF-36 (outcome) was significantly more in the conservative management group as compared to the ICD group (p = 0.020*). The mean cost of treatment was significantly more in the ICD group as compared to the conservative management group (p < 0.001*). Conclusion In our study, a TTSS (as measured by the primary care surgeon) of >7, across any number of rib fractures, was preferably predictive of management by ICD, while a <7 value was favorable for conservative management. TTSS can be used as an important tool to predict the management modality in blunt chest injury patients with ≤3 rib fractures.

Impact of prophylactic hydroxychloroquine on ultrastructural impairment and cellular SARS-CoV-2 infection in different cells of bronchoalveolar lavage fluids of COVID-19 patients.

Many drugs were recommended as antiviral agents for infection control and effective therapy to reduce the mortality rate for COVID-19 patients. Hydroxychloroquine (HCQ), an antimalarial drug, has been controversially recommended for prophylactic use in many countries, including India, to control SARS-CoV-2 infections. We have explored the effect of prophylactic HCQ from the cells of bronchoalveolar lavage fluids from COVID-19-induced acute respiratory distress syndrome patients to determine the level of infection and ultrastructural alterations in the ciliated epithelium, type II pneumocytes, alveolar macrophages, neutrophils, and enucleated granulocytes. Ultrastructural investigation of ciliated epithelium and type II pneumocytes showed lesser infections and cellular impairment in the prophylactic HCQ+ group than HCQ- group. However, macrophages and neutrophils displayed similar infection and ultrastructural alterations in both patient groups. The enucleated fragments of granulocytes showed phagocytosis of the matured virus in HCQ+ groups. The present report unveils the ultrastructural proof to complement the paradox regarding the role of prophylactic HCQ in COVID-19 patients.

Comparative evaluation of isoflurane and desflurane for postoperative cognitive decline in elderly patients: A prospective observational pilot study.

BACKGROUND: Approximately 16%-62% of patients undergoing non cardiac surgeries develop postoperative cognitive dysfunction. We compared the incidence of postoperative cognitive dysfunction in older adults aged 60-80 years who underwent open abdominal surgeries under general anaesthesia using isoflurane or desflurane and correlated it with the serum concentration of interleukin 1, interleukin 6, tumour necrosis factor alpha, amyloid ß and S100 on postoperative day 3. METHOD: Forty American Association of Anesthesiologists Physical Classification I or II patients were included after acquiring institutional ethics committee approval, registering in the Clinical Trials Registry - India, and informed written consent. They underwent open abdominal surgery under general anaesthesia and epidurals between 2017 and 2019. Patients with substance abuse or any disorder affecting cognition were excluded. Postoperative cognitive dysfunction was assessed by Stroop test, Wisconsin Card Sorting Test, Trail making test - B, Porteus Maze test, PGI memory scale, mini-mental state examination, and Bender Gestalt test the day before surgery and on the third postoperative day along with blood samples. RESULTS: Thirty-seven percent of the patients developed postoperative cognitive dysfunction. The risk was similar to isoflurane in comparison with desflurane (risk ratio: 0.65, 95% confidence interval: 0.30, 1.40). A significant percentage increase in reaction time for Porteus Maze test and Trail making test - B was noted with isoflurane (6.69 (4.20-8.94) and 8.01 (2.08-12.5), respectively) in comparison with desflurane group (13.01 (9.09-17.33), p = 0.003 and 11.62 (7.5-17.5), p = 0.017, respectively). CONCLUSION: Isoflurane and desflurane had a similar impact on the elderly for developing postoperative cognitive dysfunction and no correlation with any of the biomarkers used in the study on postoperative day 3.

Gap areas in mitigation of oral cancer: A cross-sectional study evaluating awareness and knowledge of risk factors in oral cancer in a tertiary hospital.

Purpose and Objectives: One of the main causes of the increasing oral cancer (OC) burden in India is a lack of awareness and a significant gap in knowledge about risk factors and symptomology of OC. Materials and Methods: A questionnaire-based cross-sectional study was to evaluate the knowledge and awareness about OC among 500 random patients presenting for care at a tertiary hospital in western Rajasthan which serves a wide area of western, northern, and central Rajasthan. Results: A total of 446 participants, among which 83.6% were males enrolled in the study. Much to our despair, the results showed 35.23% of the participants (P = 0.007) started their habit at age <15 years. Nearly 60.3% of the participants were well aware of the harmful temporary or permanent effects of the tobacco. Around 40.85% of the participants taking tobacco products were ignorant about their changes in the tissues (site of tobacco placement). TV and Radio (50.5%) were the main source of information of the ill effects of tobacco and form a major contribution in public awareness. More than 90% of the participants had read the warnings on the tobacco packets. No doubt participants have knowledge about the ill effects of tobacco still there was a lack in behavioral modifications for tobacco cessation, leading to nonsuccess in quitting, with actual nonunderstanding about the ill effects of tobacco and overall lack of belief in the tobacco control measures. Conclusion: Our findings have found a gap in the awareness efforts of OC for the general population and will make public health professionals, clinicians, policymakers, and government a better judge and motivate them to strengthen existing national tobacco control efforts.

Ultrastructural study confirms the formation of single and heterotypic syncytial cells in bronchoalveolar fluids of COVID-19 patients.

BACKGROUND: SARS-CoV-2 was reported to induce cell fusions to form multinuclear syncytia that might facilitate viral replication, dissemination, immune evasion, and inflammatory responses. In this study, we have reported the types of cells involved in syncytia formation at different stages of COVID-19 disease through electron microscopy. METHODS: Bronchoalveolar fluids from the mild (n = 8, SpO2 > 95%, no hypoxia, within 2-8 days of infection), moderate (n = 8, SpO2 90% to ≤ 93% on room air, respiratory rate ≥ 24/min, breathlessness, within 9-16 days of infection), and severe (n = 8, SpO2 < 90%, respiratory rate > 30/min, external oxygen support, after 17th days of infection) COVID-19 patients were examined by PAP (cell type identification), immunofluorescence (for the level of viral infection), scanning (SEM), and transmission (TEM) electron microscopy to identify the syncytia. RESULTS: Immunofluorescence studies (S protein-specific antibodies) from each syncytium indicate a very high infection level. We could not find any syncytial cells in mildly infected patients. However, identical (neutrophils or type 2 pneumocytes) and heterotypic (neutrophils-monocytes) plasma membrane initial fusion (indicating initiation of fusion) was observed under TEM in moderately infected patients. Fully matured large-size (20-100 µm) syncytial cells were found in severe acute respiratory distress syndrome (ARDS-like) patients of neutrophils, monocytes, and macrophage origin under SEM. CONCLUSIONS: This ultrastructural study on the syncytial cells from COVID-19 patients sheds light on the disease's stages and types of cells involved in the syncytia formations. Syncytia formation was first induced in type II pneumocytes by homotypic fusion and later with haematopoetic cells (monocyte and neutrophils) by heterotypic fusion in the moderate stage (9-16 days) of the disease. Matured syncytia were reported in the late phase of the disease and formed large giant cells of 20 to 100 µm.

Liposome functionalized reduced graphene oxide for rapid electrochemical sensing of bacteria.

Pathogenic bacteria represent a severe threat to global public health, particularly with the growing rate of antibiotic resistance, and, therefore, indicate a critical need for developing efficient sensing platforms. Liposome-based sensors are collocating interest due to their intrinsic fusogenic ability to fuse with the outer membrane of bacteria. However, the lack of a conducting property limits their applicability for developing biosensing platforms. In this study, we report conjugation of liposomes with reduced graphene oxide (rGO) for fabricating a rapid and sensitive biosensor for electrochemical detection of Escherichia coli (E. coli). The large surface area of rGO facilitated binding of liposomes with their surface, and the intrinsic electrical and biocompatible properties assisted electrochemical sensing of bacteria. The electrochemical response of the liposome and the rGO-liposome coated electrode shows nonconducting and conducting characteristics, respectively. A significant change in the peak current of differential pulse voltammetry with the gradual variation of bacterial density in the electrolyte was observed for the glassy carbon electrode rGO-liposome (GCE-L-rGO) surface only. The detection sensitivity of GCE-L-rGO sensors was ∼26 µA/106 cells per ml of electrolyte for varying cell densities from 3 × 103 to 3 × 104 cells/ml. The proposed sensing technique can serve as an alternative to conventional methodologies for rapid and in situ detection of bacterial load in different samples, laying the foundation for new applications in clinical diagnostics.

Comparison of Teriparatide and Combination of Cissus Quadrangularis and Dalbergia Sissoo on Bone Healing Against the Control Group in Maxillofacial Fractures: A Randomized Open-label Control Trial.

Study Design: Randomized Control Trial. Objective: A randomized control trial was planned to aim to assess whether subcutaneous Injection of Teriparatide and Tablet Reunion (combination of Cissus Quadrangularis and Dalbergia sissoo) improves maxillofacial fracture healing as compared to the control group. Methods: 24 patients of mandibular fracture with or without concomitant maxillofacial fractures were randomly divided into 3 equal groups (Group 1- Control, Group 2- Tablet Reunion, and Group 3- Injection Teriparatide) and the treatment duration was 4 weeks. Pain, fracture site mobility, bite force, serum markers, and radiographic healing were assessed preoperatively and postoperatively at regular intervals till 12 weeks. Results: Group 2 showed early pain relief, although it was insignificant. Group 3 showed the highest anterior bite force at all the time points. Change in mean posterior bite force (PBF) showed a statistically significant increase at 8th week and 12th week in intergroup comparison; however, at 12th week, Group 3 was significantly better than Group 1 and reported the highest posterior bite force compared to other groups. Serum calcium and PTH level showed no significant difference, whereas Serum ALP showed a statistically significant increase in Group 3. The radiographic assessment showed no significant difference among the 3 groups. Conclusions: Both the intervention group drugs showed a promising effect on accelerating the fracture healing and improving bite force restoration with the osteoanabolic action; however, early radiographic healing and increased serum osteogenic markers in Group 3 indicate its possible optimistic role in maxillofacial fracture healing.

No Major Age Shift During the Second Wave of COVID-19: A Mortality Analysis at a Tertiary-Level Hospital.

OBJECTIVE: The second wave of coronavirus epidemic affected India severely. We reviewed the in-hospital deaths during the second wave at a dedicated COVID hospital to better understand the clinical characteristics of patients who died during this period. METHODS: Clinical charts of all patients who were admitted and died in-hospital due to COVID-19 between 1 April 2021 and 15 May 2021 were reviewed and clinical data were analysed. RESULTS: The total number of patients admitted to hospital and the intensive care unit was 1438 and 306, respectively. The in-hospital and intensive care unit mortality was 9.3% (134 out of 1438 patients) and 37.6% (115 out of 306 patients), respectively. Septic shock with multiorgan failure was the cause of death in 56.6% of the deceased patients (n = 73) and acute respiratory distress syndrome in 35.3% (n = 47) patients. Of the deceased, 1 patient was less than 12 years old, 56.8% were between 13 and 64 years of age and 42.5% were geriatric, that is, 65 years of age or older. There were no comorbidities in 35.1% of the deceased patients. The cause of death did not vary with the age group. CONCLUSION: The in-hospital and intensive care unit mortality during the second wave was 9.3% and 37.6%, respectively. There was no major age group shift in the second wave as compared to the first wave. However, a significant number of patients (35.1%) did not have any comorbidity. Septic shock with multiorgan failure was the most common cause of death followed by acute respiratory distress syndrome.

Long-Term Yogic Intervention Improves Symptomatic Scale and Quality of Life by Reducing Inflammatory Cytokines and Oxidative Stress in Breast Cancer Patients Undergoing Chemotherapy and/or Radiotherapy: A Randomized Control Study.

INTRODUCTION: Inflammation has been associated with tumor proliferation and metastasis in breast cancer. Yoga is an ancient therapy that helps in reducing inflammation and improves the patient's quality of life (QoL) and fatigue. In the current study, we investigated the effects of long-term yogic intervention at different time points on the level of inflammatory cytokines and oxidative stress, along with the symptomatic scale and QoL in stage II/III breast cancer patients. METHODS: Ninety-six stage II/III breast cancer patients receiving chemotherapy and/or radiotherapy were enrolled and divided into two groups, non-yoga (Group I) and yoga (Group II). Participants in Group II practiced yoga five days per week for 48 weeks. The European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC-QLQ30) was used to measure the QoL and symptomatic scale. Serum levels of pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α), interferon-γ (IFN-γ) and granulocyte macrophage colony-stimulating factor (GM-CSF), and oxidative stress markers, superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and nitric oxide (NO) were measured at baseline, 16, 32, and 48 weeks in both groups. RESULTS: Yoga significantly (p<0.05) reduced the level of IFN-γ, TNF-α, and MDA and improved QoL (p<0.001) and symptomatic scale (p<0.05) in Group II patients compared to Group I. NO was upregulated in Group I whereas in Group II, it was neither decreased nor increased. CONCLUSION: These findings suggest that yoga may reduce levels of inflammatory cytokines and improve QoL and symptomatic scale in breast cancer patients receiving chemotherapy and/or radiotherapy. Yoga can be an important additional therapy during cancer treatments to cope with treatment side effects including fatigue, depression, and immunological profile, which directly affects the patient's quality of life.

Treatment Outcome Comparison Between two 3-Dimensional Plates (Y-Shaped Plate Versus Trapezoidal Condylar Plate) in Management of Mandible Condylar Fracture: A Randomized Control Trial.

Aim: To compare the treatment outcomes (clinical, functional and radiographical) using the two different 3-Dimensional plates in open reduction internal fixation of mandibular condylar fracture (MCF). Assessment of ease of fixation and fixation time were also performed. Methodology: 20 MCF patients were divided equally into two groups (Group A: Trapezoidal Condylar Plate and Group B: Y-shaped plate) and the treatment outcomes were compared. Intraoperatively time required for fixation was also compared. The patients were followed up at different timelines till 3 months. Result: Baseline parameters had statistically insignificant distribution in both groups implying effective randomization and balanced confounding factors. Intraoperatively, adequate anatomical reduction was achieved in both groups with statistically insignificant difference in time required for fixation. Postoperatively, no statistically significant difference was found in radiographic and functional parameters. None of the patients in either group reported with facial nerve injury, condylar resorption, Temporomandibular Disorders. However, 02 patients in Group A and 01 patient in Group B presented with infection, parotid fistula, and hardware failure respectively with statistically insignificant difference. Conclusion: This study concluded that the treatment outcomes were satisfactory with the use of both 3-D plate, but further studies with larger sample size and longer follow up are required.

Impact of intravenous dexamethasone on the initiation and recovery of atracurium in children: A double-blinded randomized controlled trial.

BACKGROUND: Chronic steroid intake has been associated with attenuation of neuromuscular block. Despite some promising animal and adult studies, the effect of a single dose of intravenous dexamethasone on neuromuscular blockers is not well established. Thus, the present study aimed to demonstrate the effect of dexamethasone given at the time of induction for the prevention of PONV on the action of neuromuscular blockers in children undergoing elective surgery. METHOD: After obtaining approval from the Institute Ethics Committee and written informed parental consent, 100 ASA I and II children aged 4-15 years undergoing elective surgery randomized to receive either: 0.15 mg/kg (maximum of 5 mg) of dexamethasone diluted to a total volume of 2 ml with 0.9% saline (n = 50) or 2 ml of 0.9% saline (n = 50) at the time of induction. The time interval between application of atracurium and maximum T1 depression, 25% twitch height recovery of T1, amid 25% and 75% twitch height recovery of T1, amid the 25% twitch height recovery of T1 and recovery of the neuromuscular block to a TOF ratio of 0.9, and in between the initiation of atracurium injection till the recovery of the neuromuscular block to a TOF ratio of 0.9 was defined as onset time, clinical duration, recovery index, recovery time, and total recovery period, respectively, and recorded. RESULTS: The onset time and recovery index time were lower (1.96 ± 0.39, 8.04 ± 2.14, respectively) with dexamethasone in comparison with saline (2.01 ± 0.51, 8.9 ± 3.4, respectively) but not statistically significant. The clinical duration, recovery time, and total recovery period were similar. CONCLUSION: Application of a single bolus dose (0.15 mg/kg) of dexamethasone during induction does not attenuate atracurium-induced neuromuscular blockade in children.

Explaining the Unexplained: Examining the Predictive Value of Semen Parameters, Sperm DNA Fragmentation and Metal Levels in Unexplained Infertility.

Background: There is ongoing research to find an optimum modality to predict male fertility potential. Aims: To compare the semen parameters, sperm DNA damage and seminal metal levels of Zinc, Lead and Aluminium among the male partners of couples with unexplained infertility and men with proven fertility. Settings and Design: Prospective case-control study at a tertiary level teaching hospital. Materials and Methods: One hundred male partners of couples with unexplained subfertility and 50 men with proven fertility were included in the study. Male partners of unexplained infertility couples and fertile men were compared for their semen parameters, sperm DNA Fragmentation Index (DFI) and seminal metal levels in semen. Statistical Analysis Used: Chi-square test, Student's t-test, sensitivity and specificity analysis, binomial logistic regression analysis. Results: Fertile men had statistically significantly higher mean progressive sperm motility than male partners of unexplained infertility (53.12 ± 9.89% vs. 44.81 ± 19.47%, P = 0.005). Semen volume and sperm concentration were comparable among the cases and control population. The mean sperm DFI was significantly lower among fertile men (10.83 ± 6.28 vs. 21.38 ± 10.28, P < 0.0001). Plotting the receiver-operating characteristic curve the threshold for discrimination was calculated to be 18% DFI. The sensitivity specificity and overall accuracy were 43%, 84% and 56.67%, respectively when the DFI cut-off was set at 18%. Zinc concentration in the semen had a strong positive correlation (Point Biserial correlation coefficient = 0.831) with fertility, whereas lead and aluminium had a moderate negative correlation. Conclusion: Conventional semen analysis had limited differentiating ability for unexplained infertility. The sperm DFI may be employed for explanatory purposes among couples with unexplained subfertility. A lower discriminatory threshold of DFI (18%) has better overall accuracy as opposed to a 30% cutpoint for unexplained subfertility. Among metals, Zinc was strongly correlated with fertility status.

Long-term yogic intervention decreases serum interleukins IL-10 and IL-1ß and improves cancer-related fatigue and functional scale during radiotherapy/chemotherapy in breast cancer patients: a randomized control study.

PURPOSE: Yoga improved fatigue and immunological profile in cancer survivors and has been a promising alternative therapy. Breast cancer treatments are rapidly improving, along with their side effects. This article investigated the effect of the yogic intervention at a different time interval during radiotherapy/chemotherapy on the pro- and anti-inflammatory interleukins along with the cancer-related fatigue and functional scale among patients with stage II/III breast cancer. METHODS: A total of 96 stage II/III breast cancer patients were enrolled in this study and randomly divided into two different groups. Group I (non-Yoga) received chemotherapy and/or radiotherapy and group II (Yoga) received an additional yogic intervention. Both groups were followed up for a period of 48 weeks and blood was collected at the time of enrollment, 16, 32, and 48 weeks, and serum was isolated to measure the pro- and anti-inflammatory interleukins, fatigue, and functional scale questionnaire obtained at each time point. RESULTS: Breast cancer patients in group II showed a significant improvement (p < 0.05) in the functional scale and fatigue from baseline to 48 weeks compared to group I. The yogic intervention significantly decreased (p < 0.05) the level of pro-inflammatory interleukin IL-1ß and pleiotropic interleukin IL-10 in group II compared to group I. CONCLUSION: These finding suggested that improved fatigue and functional scale is associated with a lower level of IL-1ß and IL-10. Yoga may be an important additional therapy along with the cancer treatment to help the patients with cancer-related fatigue and improve their overall immunological profile.

Clinical characteristics of COVID-19 patients who underwent tracheostomy and its effect on outcome: A retrospective observational study.

BACKGROUND: The exponential rise in Coronavirus disease 2019 (COVID-19) cases has resulted in an increased number of patients requiring prolonged ventilatory support and subsequent tracheostomy. With the limited availability of literature regarding the outcomes of COVID-19 patients with tracheostomy, we attempted to study the clinical characteristics and multiple parameters affecting the outcomes in these patients. AIM: To determine all-cause mortality following tracheostomy and its association with various risk factors in COVID-19 patients. METHODS: This retrospective study included 73 adult COVID-19 patients admitted to the ICU between 1 April, 2020 and 30 September, 2021 who underwent tracheostomy as a result of acute respiratory failure due to COVID-19. The data collected included demographics (age, sex), comorbidities, type of oxygen support at admission, severity of COVID-19, complications, and other parameters such as admission to tracheostomy, intubation to tracheostomy, ICU stay, hospital stay, and outcome. RESULTS: This study included 73 adult patients with an average age of 52 ± 16.67 years, of which 52% were men. The average time for admission to tracheostomy was 18.12 ± 12.98 days while intubation to tracheostomy was 11.97 ± 9 days. The mortality rate was 71.2% and 28.8% of patients were discharged alive. The mean duration of ICU and hospital stay was 25 ± 11 days and 28.21 ± 11.60 days, respectively. Greater age, severe COVID-19, mechanical ventilation, shock and acute kidney injury were associated with poor prognosis; however, early tracheostomy in intubated patients resulted in better outcomes. CONCLUSION: Patients with severe COVID-19 requiring mechanical ventilation have a poor prognosis but patients with early tracheostomy may benefit with no added risk. We recommend that the timing of tracheostomy be decided on a case-by-case basis and a well-designed randomised controlled trial should be performed to elucidate the potential benefit of early tracheostomy in such patients.
