Abstract
Drug-induced aseptic meningitis (DIAM) or chemical meningitis following spinal anaesthesia has rarely been reported. DIAM is caused by meningeal inflammation due to intrathecally administered drugs or secondary to systemic immunological hypersensitivity. We hereby present a case of a young adult with aseptic meningitis following neuraxial anaesthesia possibly provoked by bupivacaine. The initial cerebrospinal fluid (CSF) picture revealed neutrophilic pleocytosis and normal glycorrhachia. CSF culture was negative. The patient was put on invasive mechanical ventilation and started on intravenous antibiotics. There was a rapid improvement in clinical condition without any residual neurological deficit within the next few days. Aseptic meningitis following neuraxial anaesthesia can be prevented by strict aseptic protocols and careful inspection of visible impurities while administering the intrathecal drug. Detailed history taking, clinical examination, and focused investigations can distinguish between bacterial and chemical meningitis. Appropriate diagnosis of this entity may guide the treatment regimen, reducing hospital stay and cost.

Abstract
Reed's syndrome (RS) is a rare autosomal-dominant disorder characterised by multiple cutaneous and uterine leiomyomas, with a strong tendency for renal cell carcinoma (RCC) development. A woman in her 50s, who had previously undergone total abdominal hysterectomy due to multiple uterine leiomyomas, presented with painful nodules on her trunk and right arm for the past 6 years. These nodules were confirmed as leiomyomas through histopathology. Diagnosis of RS was established through clinicopathological correlation and positive family history, particularly her mother's. Early-onset uterine leiomyomas in patients with a similar family history should raise suspicion for RS, necessitating vigilant long-term follow-up. RCC detection requires mandatory renal imaging. Screening family members and providing genetic counselling are crucial.

Abstract
We present the measurement of the cosmic ray proton spectrum from 50 TeV to 1.3 PeV using 7.81×10^{6} extensive air shower events recorded by the ground-based GRAPES-3 experiment between 1 January 2014 and 26 October 2015 with a live time of 460 day. Our measurements provide an overlap with direct observations by satellite and balloon-based experiments. The electromagnetic and muon components in the shower were measured by a dense array of plastic scintillator detectors and a tracking muon telescope, respectively. The relative composition of the proton primary from the air shower data containing all primary particles was extracted using the multiplicity distribution of muons which is a sensitive observable for mass composition. The observed proton spectrum suggests a spectral hardening at ∼166 TeV and disfavors a single power law description of the spectrum up to the Knee energy (∼3 PeV).

Abstract
Aims and background Endotracheal tube cuff pressure (ETCP) is an important factor to determine the development of complications associated with invasive mechanical ventilation. To avoid preventable complications arising out of immobilization, frequent changes in body positioning are necessary. Such variations in body position can affect ETCP in critically ill patients who are on mechanical ventilation. So, our study aimed to assess the effect of changes in body position on ETCP in patients who are on mechanical ventilation. Materials and methods This prospective observational study included 31 critically ill intubated patients. Each study subject was first placed in a neutral starting position with a 30º head elevation. Then, they were subjected to a sequential change in body position based on the 16 most used positions as part of the critical care unit's (CCUs) daily routine. Endotracheal tube cuff pressure was measured after each position change. Data were analyzed using standard statistical tests. Results Statistically significant difference in ETCP was observed during anteflexion of neck, hyperextension of neck, left lateral flexion of neck, right lateral flexion of neck, left lateral rotation of neck, right lateral rotation of neck, 10o recumbent position, supine position, Trendelenburg position, and right lateral 30° and 45° positions. Maximum increase in ETCP was seen during anteflexion of neck (31 ± 4.5; 22-42 cm H2O). Conclusion Our study demonstrates significant deviations in ETCP from the recommended range following changes in the body position of mechanically ventilated patients, highlighting the need for the measurement of ETCP after each position change and maintenance of the same within the target range.

Significant enhancement in the cold emission characteristics of chemically synthesized super-hydrophobic zinc oxide rods by nickel doping. NANOSCALE ADVANCES 2023; 5:6944-6957.

Abstract
The current article presents a huge enhancement in the field emission characteristics of zinc oxide (ZnO) micro/nanorods by nickel doping. The synthesis of pure and nickel-doped zinc oxide (ZnO) micro/nanorods was done by a simple low-temperature chemical method. Both the as-prepared pure and doped samples were analyzed by X-ray diffraction and electron microscopy to confirm the proper phase formation and the developed microstructure. UV-vis transmittance spectra helped in determining the band gap of the samples. Fourier-Transform Infrared Spectroscopy (FTIR) spectra showed the different bonds present in the sample, whereas X-ray Photoelectron Spectroscopy (XPS) confirmed the presence of nickel in the doped sample. Photoluminescence (PL) spectra showed that after doping, the band-to-band transition was affected, whereas defect-induced transition had increased significantly. After the nickel doping, contact angle measurement revealed a significant decrease in the sample's surface energy, leading to a remarkably high water contact angle (within the superhydrophobic region). Simulation through ANSYS suggested that the doped sample has the potential to function as an efficient cold emitter, which was also verified experimentally. The cold emission characteristics of the doped sample showed a significant improvement, with the turn-on field (corresponding to J = 1 μA cm-2) reduced from 5.34 to 2.84 V μm-1. The enhancement factor for the doped sample reached 3426, approximately 1.5 times higher compared to pure ZnO. Efforts have been made to explain the results, given the favorable band bending as well as the increased number of effective emission sites.

Rational quality and cost of critical care systems are more important than individual considerations: a view from India. Postgrad Med J 2023; 99:1207-1209.

Abstract
Critical or Intensive Care Units (CCU/ICUs) play a crucial role in treating critically ill patients, but they contribute significantly to healthcare costs. In India and many other resource-limited countries, private ICU treatment is largely unaffordable for the poor and even a section of the middle class, who are not substantially insured. It is essential for all stakeholders involved in critical care to prioritize quality and cost-effectiveness. To ensure quality assurance, legally binding quality standards must be developed collaboratively by the government, professional bodies, hospital administrators, and domain experts. Regulatory benchmarks relevant to different types of ICUs can enforce adherence and transparency. Telemedicine, referral systems, and interhospital transport need improvement. Addressing attrition rates among staff and greater empowerment of formally qualified registered intensivists in the private hospitals can enhance outcomes and cost control. Long-term post-ICU recovery care is often unaffordable or unavailable in many parts of the world. Engaging families in home care and providing training in basic caregiving tasks can improve outcomes and reduce costs. In areas with limited access to qualified professionals, training of lay community caregivers and practitioners can be beneficial. Multidisciplinary post-ICU clinics and necessary telephonic handholding can support home-based patients and their families. Standardizing prices of essential necessities and promoting rational practices are crucial. System-wide efforts and novel approaches like decentralization of critical care services are necessary to ensure holistic quality and cost-effectiveness, particularly in densely populated countries with resource limitations. These innovations will not only improve care but also enhance preparedness for future pandemics.

Abstract
PURPOSE/OBJECTIVE(S) Thoracic radiation improves survival in many lung cancer patients. However, radiation-induced cardiotoxicity is a major source of morbidity and mortality in such patients. Global longitudinal strain (GLS), a novel echocardiography (ECHO) method of assessing left ventricular function, has been shown to predict long-term adverse cardiovascular risk in diverse patient populations. We hypothesized that receipt of thoracic radiation is associated with GLS changes in lung cancer patients. MATERIALS/METHODS We retrospectively identified patients with lung cancer treated at our institution between 2005-2020 who had ECHOs performed both before and after RT, and in whom GLS was extractable. ECHO Board-Certified cardio-oncologists measured GLS and left ventricular ejection fraction (LVEF) from these ECHOs. RESULTS A total of 40 patients met inclusion criteria. Median time to ECHO was 78 days prior and 172 days after RT. Two chamber (2C), 3C, 4C, and average GLS were significantly decreased after RT on paired t-test [mean difference (SD) 2.23 (3.29), 2.99 (2.78), 2.25 (3.63), 2.51 (2.66) respectively, all p < 0.001]. Thirteen patients (32.5%) had abnormal GLS (<18%) prior to RT. 5 of those 13 patients (38.5%) had abnormal LVEF (< 50%). 27/40 patients (67.5%) had an abnormal GLS or clinically significant (≥15%) drop in GLS after RT. This difference (32.5% patients pre-RT vs 67.5% post-RT) was statistically significant (p < 0.01). Among patients (n = 27) who had normal LVEF before RT, 1 patient (3.7%) developed abnormal LVEF (<50%) after RT. Backwards logistic regression showed significant interaction between heart volume receiving 5 Gray and change in GLS. CONCLUSION This cohort exhibited a significant decrease in 2C, 3C, 4C, and average GLS after RT. ∼1/3 of patients had abnormal GLS at baseline (suggesting a high-risk group for cardiac complications) and 67.5% of patients had clinically significant decrease in GLS after RT. Among the patients with normal GLS before RT, although 51.9% of patients demonstrated a clinically significant drop in GLS after RT, only 3.7% of patients developed abnormal LVEF, suggesting that this is a late occurrence. GLS changes may serve as a valuable tool for early identification of patients who are at high risk for future cardiac complications after receiving thoracic radiation.

Abstract
Cutaneous larva migrans (CLM) is a zoonotic skin disease that is frequently diagnosed in tropical and subtropical countries. Loeffler's syndrome (LS) is a transient respiratory ailment characterised by pulmonary infiltration along with peripheral eosinophilia and commonly follows parasitic infestation. We report a 33-year-old male patient who presented to a tertiary care hospital in eastern India in 2019 with LS that was attributed secondary to multifocal CLM. Treatment with seven-day course of oral albendazole (400 mg daily) coupled with nebulisation (levosalbutamol and budesonide) led to complete resolution of cutaneous lesions and respiratory complaints within two weeks. There was complete resolution of pulmonary pathology at four-weeks follow-up.

Abstract
Escherichia coli is a rare cause of community-acquired meningitis comprising about 1% of adult cases. However, it is a common pathogen in neonatal meningitis and in nosocomial setting (especially after penetrating craniocerebral injury or subsequent to neurosurgical procedures). We report a middle-aged woman, who was admitted with features of acute meningitis and subsequent investigations revealed E. coli growth in cerebrospinal fluid culture. The case is distinctive as no additional predisposing risk factors associated with gram-negative bacillary meningitis (traumatic brain injury, neurosurgical procedures, malignancy, immunosuppressive therapy, HIV infection, chronic alcoholism and diabetes) were present. She was treated with intravenous antibiotics as per sensitivity reports and discharged in clinically stable condition, without any residual neurological deficit.

Abstract
Acute-onset quadriparesis is not only debilitating and a grave concern for the patient but also perturbs the clinician as it demands early diagnosis and prompt management to prevent catastrophic outcome due to respiratory failure. Guillain-Barré syndrome (GBS) and hypokalaemia are notorious causes of acute-onset lower motor neuron (LMN) quadriparesis and warrant a rapid evaluation to necessitate early management. However, coexistence of these two entities is extremely rare and may pose a diagnostic and therapeutic challenge and mandates exclusion of either condition to avoid a poor outcome. We hereby report a case of a young woman who presented with an acute-onset LMN quadriparesis, initially found to have significant hypokalaemia with poor response to supplementation and was further evaluated to have an axonal variant of GBS.

Abstract
Rising incidence of thromboembolism secondary to COVID-19 has become a global concern, with several surveys reporting increased mortality rates. Thrombogenic potential of the SARS-CoV-2 virus has been hypothesised to originate from its ability to produce an exaggerated inflammatory response leading to endothelial dysfunction. Anticoagulants have remained the primary modality of treatment of thromboembolism for decades. However, there is no universal consensus regarding the timing, dosage and duration of anticoagulation in COVID-19 as well as need for postdischarge prophylaxis. This article seeks to review the present guidelines and recommendations as well as the ongoing trials on use of anticoagulants in COVID-19, identify discrepancies between all these, and provide a comprehensive strategy regarding usage of these drugs in the current pandemic.

Abstract
INTRODUCTION Neurological disorders in pregnancy may be observed in patients with a pre-existing neurological disorder; patients developing a primary neurological disorder during the course of pregnancy or puerperium; and in patients with primary medical disorders presenting with neurological manifestations. OBJECTIVES The objectives of the study were to find out the magnitude of neurological disorders in pregnancy in a tertiary care hospital along with assessment of proportion of women with particular disorders among total number of neurological disorders during the course of pregnancy or puerperium (6 weeks after child birth) and also to elicit the effect of neurological disorders on pregnancy outcome, if any. METHODS A prospective observational longitudinal study was carried out in a tertiary care centre of Eastern India from July 2018 to June 2020 including all pregnant women attending the department of Obstetrics and Gynaecology. We screened 886 pregnant women, out of which 91 cases were identified and investigated. For the purpose of comparison of fetal and maternal outcome, 91 control subjects were chosen from the screened patients in a randomized fashion, so that the baseline characteristics of the two groups were comparable Results: In our study, 10.3% population had neurological disorders, among which 30.8% had primary headache, 3.2% had secondary headache, 8.5% had neurological low back pain, 19.1% had epilepsy, 6.4% had cerebrovascular disorders, 27.6% had peripheral neuropathy, 4.2% had other disorders such as neuropsychiatric Wilson's disease, myasthenia gravis and compressive myelopathy. Moreover, 10.2% of the total study population was hypertensive and 2.9% were diabetic. CONCLUSION 10.3% mothers did have some neurological disorder, the commonest of which was migraine (primary headache) followed by carpal tunnel syndrome (peripheral neuropathy) and neurological low back pain. Overall fetomaternal outcomes were favorable barring cerebro-vascular disorder and Posterior reversible encephalopathy syndrome (PRES). We recommend screening for neurological disorder from early pregnancy for early detection and appropriate management of that condition.

Abstract
Millard-Gubler syndrome (MGS) is a ventral pontine syndrome due to an ipsilateral involvement of abducens and facial nerve with a contralateral hemiparesis or hemiplegia. Although classically described as a vascular brainstem syndrome, various other aetiologies such as infection or demyelination may lead to MGS. In this case, a young female presented with MGS, which was attributed to a strategically located infective granuloma of the brainstem. In countries, where tuberculosis is still considered an endemic, central nervous system involvement due to tuberculosis may have protean manifestations.

Abstract
Toxoplasma infection can be congenital or acquired. Infection with <i>Toxoplasma gondii</i> can result in multi-organ involvement in immunocompromised patients; whereas in immunocompetent patients, it usually remains asymptomatic. <i>Toxoplasma</i> is a rare cause of isolated lymphadenopathy especially in immunocompetent individuals, though it is a common manifestation of this protozoal infection. We present a 27-year-old male who presented to us with isolated cervical lymphadenopathy. Histopathology and serological studies confirmed the diagnosis of toxoplasma lymphadenopathy. It usually affects the posterior cervical group of lymph nodes, but in our case, it had also affected anterior group and presented without any constitutional symptom. The patient was treated with cotrimoxazole double strength tablet once daily for 1 month and responded well.

Abstract
Polymyositis is an immune-mediated inflammatory myopathy usually presenting with weakness of proximal muscles in a symmetric pattern. Generalised subcutaneous oedema as presenting feature of inflammatory myopathy, especially polymyositis, has rarely been reported. We report here a case of a young woman who was admitted to our facility with generalised severe subcutaneous oedema. During hospital stay, she gradually developed significant proximal muscle weakness with bulbar symptoms. The initial presentation of the patient masqueraded with other causes of anasarca. However, detailed clinical features, laboratory evaluation, electromyography and muscle biopsy clinched the diagnosis of polymyositis. She was treated with systemic corticosteroids and azathioprine. The patient responded well to treatment and the swelling gradually subsided.

Abstract
Objectives: The objective of this study is to analyse detailed clinical presentations, imaging findings, and outcome in a series of 17 cases (n = 17) with neurological complications following acute varicella infection. Methods: It is an observational study on the patients who presented to the neurology outpatient department of our institute with neurological abnormalities following acute varicella infection within the last 3 months. Results: Neuroimaging, either computed tomography or magnetic resonance imaging, cerebrospinal fluid analysis, electroencephalography and nerve conduction studies were performed in all the patients along with other specialized investigations as per clinical context. The age of presentation varied from childhood to middle age (median age was 23 years) and range of clinical spectrum was also wide. Peripheral nervous system involvement was more common in the form of Guillain–Barré syndrome (29.4%) and isolated lower motor neuron facial nerve palsy (23.5%) compared to central nervous system (CNS) involvement. CNS involvement was documented in the form of ataxia (11.76%), myelopathy (17.6%), stroke (5.88%) and encephalitis (5.88%). Conclusion: Chickenpox is a common viral disease and most patients recover without any complication. Although rare, neurological complications following acute varicella infection may have myriad presentations ranging from lower motor neuron facial palsy to life-threatening encephalitis. Compared to other studies, varicella encephalitis and ataxia were not so common in our study group. Response to therapy was uniformly good except in the patients presenting with ataxia. Response was particularly good to central and peripheral demyelinating disorders.

Abstract
BACKGROUND AND AIMS The novel coronavirus disease (COVID-19) caused by SARS-CoV-2 has turned the world topsy-turvy since its onset in 2019. The thromboinflammatory complications of this disease are common in critically ill patients and associated with poor prognosis. Symmetrical peripheral gangrene (SPG) is characterized by symmetrical distal gangrene in absence of any large vessel occlusion or vasculitis and it is usually associated with critical illness. Our aim was to report the clinical profile and outcome of patients diagnosed with SPG associated with COVID-19. To the best of our knowledge, no such similar cases have been reported till date. METHODS In this case series, we have discussed the clinical presentation, laboratory parameters and outcome in a series of two patients of SPG associated with COVID-19 and also compared those findings. Due to paucity of data, we also reviewed the literature on this under-diagnosed and rarely reported condition and association. RESULTS Two consecutive patients (both males, age range: 37-42 years, mean: 39.5 years) were admitted with the diagnosis of COVID-19 associated SPG. Both patients had clinical and laboratory evidence of disseminated intravascular coagulation (DIC). Leucopenia was noted in both patients. Despite vigorous therapy, both patients succumbed to their illness within a fortnight of admission. CONCLUSION SPG in the background of COVID-19 portends a fatal outcome. Physicians should be aware of its grim prognosis.

Abstract
Advancement in technology has given students and institutes an educational, interactive, and diagnostic aid with virtual reality functionality known as the Anatomage table. This review analyses the various spheres of the medical field where the 3D virtual tool is being used and assesses its acceptability, convenience, and practical application. A search for relevant studies in various databases namely Pubmed, Embase, Wiley Library, and Google Scholar was performed, and the data was compiled to understand the use of the Anatomage table. The search yielded a total of 24 studies that focused on the use of the Anatomage table. Eleven articles focused on using Anatomage as a learning tool and 13 described the perception of the Table. Anatomage table offers an excellent tool for learning anatomy by virtual dissection. The tool is not only used as a teaching aid, but also as a diagnostic and planning tool in residency programs. Adding the tool as an educational aid boosts the existing curriculum and helps to counter the challenges with cadaveric dissection. The equipment cost and its maintenance charges may be a deciding factor for the underutilization of the tool in developing countries.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease with multisystem involvement. Superior vena cava (SVC) syndrome is mainly caused by malignant tumors such as lung carcinoma, lymphoma, and metastatic tumors. We report a 20-year-old woman who was admitted with features of SVC syndrome secondary to SVC thrombus. Further evaluation confirmed the diagnosis of SLE without associated antiphospholipid syndrome (APS). The patient was treated with heparin with oral anticoagulant, steroids, and hydroxychloroquine. Complete resolution of thrombus was documented within a few weeks. SVC thrombosis as an initial presenting feature of SLE without associated APS has not been reported so far in the literature.
