ABSTRACT
Abstract Background and aims: Dexamethasone as adjunct to local anesthetic solution improves the quality of brachial plexus block (BPB). However, evidence for its efficacy at low doses (< 4 mg) is lacking. This study was designed to evaluate the duration of analgesia attained with low dose dexamethasone as adjuvant to local anesthetic for creation of arteriovenous fistula (AVF) under BPB. Methods: Sixty-six patients scheduled for AVF creation were randomly allocated to receive either saline (control) or 2 mg dexamethasone, together with 0.5% ropivacaine and 0.2% lignocaine. The primary outcome was duration of analgesia, defined as time from performing the block to the first analgesic request. The secondary outcomes were time from injection to complete sensory block, time from injection to complete motor block, duration of motor block, postoperative analgesic consumption, and fistula patency at three months. Results: All the blocks were effective. In the group that received dexamethasone, the time to first analgesic request was significantly delayed (432 ± 43.8 minutes vs. 386.4 ± 40.2 minutes; p < 0.01). The onset of sensory and motor blockade occurred faster in dexamethasone group and overall analgesic consumption was also reduced. However, dexamethasone addition did not prolong the duration of motor block. There was no statistically significant difference in the patency of fistulas between the two groups at three months. (p = 0.34). Conclusion: Addition of low-dose perineural dexamethasone to local anesthetic solution significantly prolonged the duration of analgesia. Further trials are warranted to compare the adverse effects between dexamethasone doses of 4 mg and lower.

ABSTRACT Introduction: Idiopathic steroid resistant nephrotic syndrome (SRNS) has variable outcomes in children. The primary objective of the present study was to assess the cumulative remission rate and the secondary objectives were to assess factors affecting the remission status, kidney function survival, and adverse effects of medications. Methods: One hundred fourteen patients with SRNS were included. Calcineurin inhibitor-based treatment protocol along with prednisolone and angiotensin-converting enzyme inhibitor were used, and patients were followed over 5 years. Results: Median age was 4.5 years; 53.5% of cases were between 1 to 5 years of age. Sixty-two patients (54.4%) were at initial stage and 52 (45.6%) were at a late SRNS stage. Median eGFRcr was 83.5 mL/min/1.73m2 at presentation. Of the 110 patients, 63 (57.3%) achieved remission [complete remission 30 (27.3%), partial remission 33 (30%)], and 47 (42.7%) had no remission. Kidney function survival was 87.3% and 14 cases (12.7%) had progression to CKD (G3-8, G4-3, G5-1, and G5D-2). Median duration of follow up was 36 months (IQR 24, 60). Age of onset, cyclosporine/tacrolimus, eGFRcr, and histopathology (MCD/FSGS) did not affect remission. Similarly, remission status in addition to age of onset, drug protocol, and histopathology did not significantly affect kidney function during a period of 5 years. Hypertension, cushingoid facies, short stature, cataract, and obesity were observed in 37.7, 29.8, 25.5, 17.5, and 0.7% of cases, respectively. Conclusion: About half of the cases achieved remission. Age of onset of disease, cyclosporine/tacrolimus use, and histopathological lesion neither affected remission status nor short-term kidney function survival in SRNS.
RESUMO Introdução: A síndrome nefrótica idiopática córtico-resistente (SNICR) apresenta desfechos variáveis em crianças. O objetivo principal deste estudo foi avaliar a taxa de remissão cumulativa. Os objetivos secundários foram avaliar fatores que afetam status de remissão, sobrevida da função renal e efeitos adversos de medicamentos. Métodos: Foram incluídos 114 pacientes com SNCR. Utilizou-se protocolo de tratamento baseado em inibidores de calcineurina juntamente com prednisolona e inibidor da enzima conversora de angiotensina. Os pacientes foram acompanhados durante 5 anos. Resultados: A idade mediana foi 4,5 anos; 53,5% dos casos tinham entre 1 e 5 anos. 62 pacientes (54,4%) estavam em estágio inicial; 52 (45,6%) em estágio tardio da SNCR. A TFGecr mediana foi 83,5 mL/min/1,73 m2 na apresentação. Dos 110 pacientes, 63 (57,3%) alcançaram remissão [remissão completa 30 (27,3%), remissão parcial 33 (30%)], e 47 (42,7%) não apresentaram remissão. A sobrevida da função renal foi 87,3%; 14 casos (12,7%) progrediram para DRC (G3-8, G4-3, G5-1, G5D-2). A duração mediana do acompanhamento foi 36 meses (IIQ 24, 60). Idade no início, ciclosporina/tacrolimus, TFGecr e histopatologia (DLM/GESF) não afetaram a remissão. Igualmente, status de remissão, além da idade no início, protocolo de medicamentos e histopatologia não afetaram significativamente a função renal por 5 anos. Observou-se hipertensão, fácies cushingoide, baixa estatura, catarata e obesidade em 37,7; 29,8; 25,5; 17,5; e 0,7% dos casos, respectivamente. Conclusão: Aproximadamente metade dos casos alcançou remissão. Idade no início, uso de ciclosporina/tacrolimus e lesão histopatológica não afetaram o status de remissão nem a sobrevida da função renal a curto prazo na SNICR.
ABSTRACT
Purpose: To analyze the demographics and clinical outcomes of posterior chamber phakic intraocular (IOL) implantation for refractive amblyopia in children and adolescents. Methods: A prospective interventional study was performed on children and adolescents with amblyopia at a tertiary eye care center from January 2021 to August 2022. Twenty?three eyes of 21 anisomyopic and isomyopic amblyopia patients operated for posterior chamber phakic IOL (Eyecryl phakic IOL) as a treatment for amblyopia were included in the study. Patient demographics, pre? and postoperative visual acuity, cycloplegic refraction, anterior and posterior segment examination, intraocular pressure, pachymetry, contrast sensitivity, endothelial count, and patient satisfaction scores were evaluated. Patients were followed up at day 1, 6 weeks, 3 months, and 1 year after surgery, and visual outcomes and complications were documented. Results: The mean age of patients was 14.16 ± 3.49 years (range: 10–19 years). The mean intraocular lens power was ? 12.20 diopter spherical (DS) in 23 eyes and ? 2.25 diopter cylindrical (DC) in four patients. The mean unaided distant visual acuity (UDVA) and best?corrected visual acuity (BCVA) were 1.39 ± 0.25 and 0.40 ± 0.21 preoperatively on the log of minimum angle of resolution (logMAR) chart. Postoperatively, the visual acuity improved by 2.6 lines in 3 months period and maintained till 1 year. Postsurgery, contrast sensitivity in the amblyopic eyes significantly improved, and the average endothelial loss recorded was 5.78% at 1 year, which was statistically insignificant. Patient satisfaction score was statistically significant, with 4.736/5 recorded on the Likert scale. Conclusion: Posterior chamber phakic IOL is a safe, effective, and alternative method for treating amblyopia patients who are noncompliant with glasses, contact lenses, and keratorefractive procedures.
ABSTRACT
Background & objectives: A combination of resistant and susceptible Mycobacterium tuberculosis (MTB) isolated from clinical specimens is referred to as heteroresistance. Heteroresistance leads to difficulties in drug resistance testing and may adversely affect treatment outcomes. The present study estimated the proportion of heteroresistance among MTB in clinical samples of presumptive drug-resistant tuberculosis (TB) patients in Central India. Methods: A retrospective analysis of data generated from line probe assay (LPA) at a tertiary care hospital in Central India between January 2013 and December 2018 was carried out. A heteroresistant MTB in a sample was indicated by the presence of both wild-type and mutant-type patterns on an LPA strip. Results: Data analysis was carried out on interpretable 11,788 LPA results. Heteroresistance in MTB was detected in 637 (5.4%) samples. Of these, heteroresistance in MTB was detected in 413 (64.8%), 163 (25.5%) and 61 (9.5%) samples with respect to rpoB, katG and inhA genes, respectively. Interpretation & conclusions: Heteroresistance is considered a preliminary step in the development of drug resistance. Delayed or suboptimal anti-tubercular therapy in patients with heteroresistance of MTB may elicit full clinical resistance and negatively impact the National TB Elimination Programme. Further studies are, however, needed to determine the impact of heteroresistance on treatment outcomes in individual patients.
ABSTRACT
Hirayama disease, or brachial monomelic amyotrophy, is not a common neurological disease characterized by unilateral or asymmetric bilateral lower motor weakness of distal upper limbs. The basic pathophysiology is compression of the dural sac and spinal cord during flexion of the neck. A case of a 21-year-old male presented with chief complaints of tremors in both hands (right more than left) with gradually progressive weakness of the right hand and forearm. Electromyography (EMG), nerve conduction velocity (NCV), and magnetic resonance imaging (MRI) neck in flexion showed focal atrophy of lower cervical myotomes and confirmed the diagnosis of monomelic amyotrophy.
ABSTRACT
Objectives@#The aim of the study was to quantify and compare craniofacial asymmetry in subjects with and without symptoms of temporomandibular joint disorders (TMDs). @*Materials and Methods@#A total of 126 adult subjects were categorized into two groups (63 with a TMDs and 63 without a TMDs), based on detection of symptoms using the Temporomandibular Joint Disorder-Diagnostic Index (TMD-DI) questionnaire. Posteroanterior cephalograms of each subject were traced manually and 17 linear and angular measurements were analyzed. Craniofacial asymmetry was quantified by calculating the asymmetry index (AI) of bilateral parameters for both groups. @*Results@#Intra- and intergroup comparisons were analyzed using independent t-test and Mann–Whitney U test, respectively, with a P<0.05 considered statistically significant. An AI for each linear and angular bilateral parameter was calculated; higher asymmetry was found in TMD-positive patients compared with TMD-negative patients. An intergroup comparison of AIs found highly significant differences for the parameters of antegonial notch to horizontal plane distance, jugular point to horizontal plane distance, antegonial notch to menton distance, antegonial notch to vertical plane distance, condylion to vertical plane distance, and angle formed by vertical plane, O point and antegonial notch. Significant deviation of the menton distance from the facial midline was also evident. @*Conclusion@#Greater facial asymmetry was seen in the TMD-positive group compared with the TMD-negative group. The mandibular region was characterized by asymmetries of greater magnitude compared with the maxilla. Patients with facial asymmetry often require management of temporomandibular joint (TMJ) pathology to achieve a stable, functional, and esthetic result. Ignoring the TMJ during treatment or failing to provide proper management of the TMJ and performing only orthognathic surgery may result in worsening of TMJ-associated symptoms (jaw dysfunction and pain) and re-occurrence of asymmetry and malocclusion. Assessments of facial asymmetry should take into account TMJ disorders to improve diagnostic accuracy and treatment outcomes.
ABSTRACT
Abstract Background Post-spinal anesthesia hypotension is of common occurrence, and it hampers tissue perfusion. Several preoperative factors determine patient susceptibility to hypotension. This study aimed to assess the effectiveness of the Inferior Vena Cava Collapsibility Index (IVCCI) for predicting intraoperative hypotension. Methods One hundred twenty-nine adult patients who were scheduled for elective surgical procedures after administration of spinal (intrathecal) anesthesia were included in the study. Ultrasound evaluation of the Inferior Vena Cava (IVC) was done in the preoperative area, and the patients were shifted to the Operating Room (OR) for spinal anesthesia. An independent observer recorded the change in blood pressure after spinal anesthesia inside the OR. Results Twenty-five patients developed hypotension (19.37%). Baseline systolic blood pressure and mean blood pressures were statistically higher in those patients who developed hypotension (p= 0.001). The logistic regression analysis for IVCCI and the incidence of hypotension showed r2 of 0.025. Receiver Operating Characteristic (ROC) curve analysis demonstrated the Area Under the Curve (AUC) of 0.467 (95% Confidence Interval, 0.338 to 0.597; p= 0.615). Conclusions Preoperative evaluation of IVCCI is not a good predictor for the occurrence of hypotension after spinal anesthesia.

Abstract Background Melatonin has been studied to have anxiolytic, sedative, and analgesic effects. However, there is limited data on the effect of melatonin in the attenuation of hemodynamic response to intubation. We aimed to study whether preanesthetic oral melatonin attenuates hemodynamic responses to intubation and anesthetic requirements. Methods Sixty-four patients scheduled for laparoscopic cholecystectomy were randomized into melatonin or placebo group (n = 32 each). Melatonin group received two tablets (3 mg each) of melatonin, and the placebo group received two tablets of vitamin D3 120 min before induction. Hemodynamic parameters were recorded during induction and postintubation for 15 minutes. Total induction dose of propofol, total intraoperative fentanyl consumption, and adverse effects of melatonin were also noted. Results Postintubation rise in heart rate (HR) was less in the melatonin group compared to the placebo group (10.59% vs. 37.08% at 1 min, respectively) (p< 0.0001). Maximum percentage increase in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean blood pressure (MBP) was lesser in melatonin group than placebo group (SBP 9.25% vs. 37.73%, DBP 10.58% vs. 35.51%, MBP 9.99% vs. 36.45% at 1 min postintubation. respectively) (p< 0.0001). Induction dose of propofol (1.42 mg.kg-1 vs. 2.01 mg.kg-1) and the number of patients requiring additional fentanyl intraoperatively (3 vs. 11) were also significantly reduced in the melatonin group. Conclusion Premedication with 6 mg of oral melatonin resulted in significant attenuation of postintubation rise in HR, SBP, DBP, and MBP. It also reduced the induction dose of propofol, total intraoperative fentanyl consumption without any adverse effects.

Abstract Background: Nasogastric tube insertion and confirmation of its position can be difficult in the anesthetized patient. The purpose of the present study was to compare the bubble technique with the conventional method for confirmation of nasogastric tube placement in these patients. Methods: Two hundred sixty adult patients, aged between 20-70 years, posted for surgeries requiring general anesthesia, tracheal intubation, and a nasogastric tube were enrolled in this study. Patients were randomized into 2 groups: Group B (Bubble group) and Group C (Control group). In Group C, a conventional technique using a lubricated nasogastric tube was positioned through the nostril with head remained neutral. In Group B, 2% lidocaine jelly was added to the proximal end to form a single bubble. The correct placement of the nasogastric tube in the stomach was confirmed by fluoroscopy by an independent observer intraoperatively. Results: The duration of nasogastric tube insertion was 57.2 ± 13.3seconds in Group B and 59.8 ± 11.9seconds in Group C (p = 0.111). The confirmation rate of the bubble technique was 76.8% (95% CI: 68.7-83.3), which was significantly better than the conventional method where the confirmation rate was 59.7% (95% CI 50.9-67.9), p< 0.001. When compared to fluoroscopy, bubble technique was found to have a sensitivity of 92.3% (95% CI: 85.6-96.1) with specificity of 81.0% (95% CI: 60.0-92.3), positive predictive value of 96.0% (95% CI: 90.2-98.4), and a moderate negative predictive value of 68.0% (95% CI: 48.4-82.8). Conclusions: The bubble technique of nasogastric tube insertion has a higher confirmation rate in comparison to the conventional technique.

ABSTRACT
Ventilatory management of patients with traumatic cervical spinal cord injury (CSCI) is a complex and controversial area of critical care medicine. Despite significant advances in our understanding of the pathophysiology of CSCI and the development of novel interventions, there remains a lack of consensus about the optimal approach to ventilatory management in these patients. Some of the key controversies in CSCI ventilatory management include timing of tracheal intubation, non-invasive ventilation versus invasive ventilation, high versus low tidal volume, and early versus late tracheostomy. The objective of this review is to discuss the existing controversies and provide an insight on the current evidence.
ABSTRACT
Background:Tracheo?bronchomalacia (TBM) is the weakness in the structural integrity of the cartilaginous ring and arch. It may occur in isolation with prematurity or secondarily in association with various congenital anomalies. Bronchomalacia is more commonly associated with congenital heart diseases. The conventional treatment options include positive pressure ventilation with or without tracheostomy, surgical correction of external compression and airway stenting. Aim: To use “synchronized” nasal Dual positive airway pressure (DuoPAP), a non?invasive mode of ventilation as an alternative treatment option for bronchomalacia to avoid complications associated with conventional treatment modalities. Study Design: Prospective observational study conducted in Army Hospital Research and Referral from Jul 2019 to Dec 2020. Material and Methods: We diagnosed seven cases of TBM post?cardiac surgery at our institute, incidence of 4.2%. Four infants were diagnosed with left sided bronchomalacia, 2 were diagnosed with right sided bronchomalacia and one with tracheomalacia. Those infants were managed by “synchronized” nasal DuoPAP, a first in ventilation technology by Fabian Therapy Evolution ventilator (Acutronic, Switzerland). Results: All seven infants showed significant improvement with synchronized nasal DuoPAP both clinically as well as radiologically. None of the infant required tracheostomy and discharged to home successfully. Conclusion: The synchronized nasal DuoPAP is a low cost and effective treatment option for infants with TBM. It could be attributed to synchronization of the breaths leading to better tolerance and compliance in paediatric age group
ABSTRACT
BACKGROUND The burden of cardiovascular diseases (CVDs) and response to health systems vary widely at the subnational level in India. Our study aimed to assess the variation in state-level access to medicines for CVDs by comparing the essential medicines lists (EMLs) at the national and subnational levels in India and by rapid appraisal of the existing policies and processes of drug procurement. METHODS We assessed the inclusion of six classes of medicines for CVDs in the recent and publicly available national and subnational EMLs from July to September 2018 in the states of Telangana and Madhya Pradesh. We examined the drug procurement and distribution policies and processes using documentary review and five key informant interviews between March and June 2018. RESULTS The WHO’s EML, India’s national EML, and 21 of 28 publicly available (75%) Indian state and Union Territory EMLs included all six classes of essential medicines for CVDs. However, some medicines were not included in the policy packages of essential medicines meant for primary health centres. Both the states used centralized tendering and decentralized distribution as part of the public sector drug procurement process. The requirement was based on the previous year’s consumption. The approximate time between procurement planning and distribution was 7–8 months in both the states. CONCLUSION Substantial variation exists in the selection of drugs for CVDs in EMLs at the subnational level in India. Improving forecasting techniques for requirement of medicines and reducing time lags between forecasting and distribution to health facilities may allow for better access to essential medicines.
ABSTRACT
Dual anti-platelet therapy (DAPT) and statins are recommended by guidelines for the management of cardiovascular diseases (CVDs), even though the duration of treatment is guided by ischemic and bleeding risk. Clopidogrel and aspirin are the most commonly used DAPT in CVDs. Adding a statin to DAPT is helpful in reducing the thrombosis risk. Fixed-dose combination (FDC) therapy in CVD can help to address the factors of convenience, compliance, control, cost, and complication better than free drug combinations. Therefore, the FDC of rosuvastatin (10 mg or 20 mg) + clopidogrel (75 mg) + aspirin (75 mg) is likely to improve compliance in CVD patients, thereby reducing adverse cardiovascular outcomes and cost of treatment. There is lack of awareness on long term benefits of this FDC in Indian patients.
ABSTRACT
Cytokine storm also known as cytokine releasing syndrome is due to elevate level of circulating cytokine and hyper action that can be triggered by some factor like virus, bacteria or other epigenetic factors. In this era of communicable disease, COVID-19 is such a disease which shows manifestation in the form of cytokine storm. Increase level of cytokine like interleukin-6 etc in the blood causes destruction of normally functioning cell leads to dangerous life-threatening condition like ARDs. Cytokines are immunomodulating agents composed of soluble proteins, peptides and glycoproteins secreted by haemopoietic and non-haemopoietic cells in response to various stimuli. Their main role is in molecular interaction between various cells of the immune system. Cytokines are nothing but just the immune markers which hyperactivation leads to cytokine storm. There is not any description of such pathogenesis in Ayurveda. But Ayurveda clearly defined some concepts of immunity such Asvyadhikshamatva, Oja, Bala, Vyadhibighatakarabhaba and Rasayana. In Covid-19, researcher found that such people are more vulnerable to disease and its severity. Such vulnerability depends upon person response to illness. Ayurveda may explain this vulnerability through its concepts of preventive, personalized and rejuvenation. The present review focused on cytokine storm and its understanding in perspective of Ayurvedic concepts of immunity
ABSTRACT
Background: Epilepsy is a common chronic non-communicable neurological disorder in which the brain function is impaired. Cognitive function is more frequently impaired in people with epilepsy than in the general population. The neurocognitive outcome of epilepsy in children and adults is vital for social prognosis and quality of life assessment. Cognitive changes in epilepsy have multifactorial etiology, including the epilepsy itself, age at onset, duration of epilepsy, treatment of epilepsy, reaction to epilepsy and any associated brain dysfunction and /or damage. This study was conducted to check association of neurocognitive impairment with the socio-demographic factors and disease associated factors in patients with epilepsy. Methodology: This study was a single centre cross-sectional study in which 96 patients were included. Severity of neurocognitive impairment was measured by Addenbrookes’ Cognitive Examination- R (ACE- R) score. Results: Out of 96 patients, neurocognitive impairment was seen in 23 (23.95%) patients. Conclusions: This study shows that neurocognitive impairment was found to be more when the age at onset of epilepsy was less, when the duration of the illness was more and when frequency of seizure was higher. Conclusion: Neurocognitive impairment is noted in patients with epilepsy and must be treated in the long- term management of epilepsy
ABSTRACT
Background & objectives: Zinc is a crucial micronutrient in adolescence, required for promoting growth and sexual maturation. Adolescents of some tribes may be at high risk of zinc deficiency due to dietary inadequacy and poor bioavailability of zinc from plant-based diets. This study aimed to evaluate the risk of zinc deficiency by estimating prevalence of inadequate zinc intake, prevalence of low serum zinc and stunting among tribal adolescents. Methods: A cross-sectional community-based survey was conducted among adolescents (10-19 yr) in three purposively selected districts where Bhil, Korku and Gond tribes were in majority. Structured data collection instrument comprising information about sociodemographic characteristics and dietary recall data was used. Anthropometric assessment was conducted by standardized weighing scales and anthropometry tapes, and blood sample was collected from antecubital vein into trace element-free vacutainers. Serum zinc was estimated using an atomic absorption spectrophotometer. Results: A total of 2310 households were approached for participation in the study, of which 2224 households having 5151 adolescents participated. Out of these enlisted adolescents, 4673 responded to dietary recall (90.7% response rate). Anthropometry of 2437 participants was carried out, and serum zinc was analyzed in 844 adolescents. The overall prevalence of dietary zinc inadequacy was 42.6 per cent [95% confidence interval (CI) 41.2 to 44.1] with reference to the estimated average requirement suggested by International Zinc Nutrition Consultative Group (IZiNCG) and 64.8 per cent (95% CI 63.4 to 66.2) with Indian Council of Medical Research-recommended requirements. Stunting was observed in 29 per cent (95% CI 27.2 to 30.8) participants. According to IZiNCG cut-offs, low serum zinc was detected in 57.5 per cent (95% CI 54.1 to 60.8) of adolescents, whereas it was 34.4 per cent (95% CI: 31.2-37.5) according to the national level cut-off. Interpretation & conclusions: Risk of dietary zinc inadequacy and low serum zinc concentration amongst adolescents of the Gond, Bhil and Korku tribes is a public health concern.
ABSTRACT
It is vital to identify the ejaculate with good freezability by determining the biochemical makeup of the ejaculate at the pre-freeze stage. The present study targeted to assess the use of the protein estimates and profiles at the pre-freeze stage as markers of freezability in Frieswal populations. Storing the proteins for proteomic studies is always tricky in the case of animal studies, where accessibility to liquid nitrogen is limited. Hence alternative storing approaches need to be optimized. The second part of this study examined the protein concentration and protein profiles of RNALater and frozen stored sperm cells to assess the use of RNALater preservation in sperm proteomic studies. Sperm and seminal plasma protein concentrations were quantified using Bradford assay, and total protein quantities were derived. The seminal plasma and sperm protein profiles were generated with SDS-PAGE. The protein estimates and SDS-PAGE profiles of good and poor freeze-groups were similar. Also, sperm and seminal plasma protein concentration were not correlated with the semen volume and sperm count. Even though the yield was comparatively less, the protein profiles of sperm preserved by RNALater were similar to that of frozen sperms. The present study results indicate that the protein estimates and qualitative profiles of sperm and seminal plasma proteins may not be sufficient to reveal the differences in the proteome of good and poor freezable bulls at the macro level. Hence, the protein estimates and profiles of neat semen may not be helpful for the prediction of freezability at the pre-freeze stage. Secondly, this study indicates that RNALater preservation helps store sperms for proteome analysis studies.
