Abstract
Echinococcus granulosus causes hydatid cysts, a significant zoonotic and pulmonary parasitic disease that can mimic various pathologies and is often harder to manage than the disease itself. A hydatid cyst is considered a significant health problem in India, Iran, China, and Mediterranean countries, which lack satisfactory environmental health, preventive medicine, and veterinarian services. Echinococcosis continues to be a major community health burden in several countries, and in some terrains, it constitutes an emerging and re-emerging disease. Cystic echinococcosis is the most common human disease of this genus, and it accounts for a significant number of cases worldwide. Herein, a case involving an 11-year-old presenting with fever, dry cough, and right hypochondrial pain is presented, where imaging revealed a hydatid cyst in the lung. Surgical removal of the cyst was achieved through right posterolateral thoracotomy under one-lung ventilation and anesthesia using intubation with a double-lumen endotracheal tube (DLET or DLT), highlighting surgery as the primary treatment despite the lack of consensus on surgical methods. This case underscores the effectiveness of individualized, parenchyma-preserving surgery for even large, uncomplicated cysts, indicating a positive prognosis.

Abstract
PURPOSE Infection in the neurocritical care unit ( NCCU) can cause significant mortality and morbidity. Autonomic nervous system plays an important role in defense against infection. Autonomic dysfunction causing inflammatory dysregulation can potentiate infection. We aimed to study the relationship between autonomic dysfunction and occurrence of infection in neurologically ill patients. METHODS Fifty one patients who were on mechanical ventilation were prospectively enrolled in this study. Autonomic dysfunction was measured for three consecutive days on admission to NCCU using Ansiscope. Patients were followed up for seven days to see the occurrence of infection. Infection was defined as per centre of disease control definition. RESULTS A total of 386 patients were screened for eligibility. 68 patients satisfied the eligibility criteria and 51 patients were finally included in the study. The incidence of infection was 74.5%. The commonest infection was pulmonary infection (38.8%) followed by urinary tract infection (33.3%), blood stream infection(14.8%), central nervous system infection (11.1%) and wound site infection (3.7%). The degree of autonomic dysfunction (AD) percentage was more in infection group (37.7% (25.2-49.7)) compared to non infection group (23.5% (18-33.5)) and maximal on day 3 (P = 0.02). Patients with increasing trend of AD% from day 1 to day 3 had the highest infection rates. The length of NCCU stay (20(10-23) days and mortality (42.1%) was higher in infection group (p < 0.001). CONCLUSION AD assessment can be used as a tool to predict development of infection in NCCU. This can help triage and institute early investigation and treatment.

Abstract
Ventricular septal defects (VSDs) are a prevalent congenital heart anomaly demanding safe and lasting interventions. This paper explores the application of Invengenx® bovine pericardial patch (Tisgenx, Irvine, California), a promising biomaterial, in VSD repair. We present two case studies: a seven-month-old infant and a three-year-old child undergoing VSD closure using autologous and bovine pericardial patches, respectively. Both patients tolerated the procedures well, experiencing no intra-operative complications and demonstrating excellent postoperative recovery. Echocardiography postoperatively showed no complications and improved clinical outcomes. Notably, the pericardial patches exhibited excellent integration and suture retention, highlighting their durability and compatibility with the growing heart. These cases establish the feasibility and effectiveness of the Invengenx® pericardial patch for VSD repair. The favorable outcomes in terms of safety and efficacy support the potential of this biomaterial as a valuable alternative in pediatric cardiac surgery, particularly for complex VSDs or patients with contraindications to synthetic patches. Further research is crucial to unlock the full potential of bovine pericardium as a durable and advantageous option for VSD repair in a broader range of pediatric patients.

Abstract
Congenital pulmonary airway malformations (CPAM) compose the major part of congenital lung malformations (CLM) and have traditionally been treated by pulmonary lobectomy. In terms of surgical strategy, lobectomy has conventionally been the preferred treatment for CPAM localized to a single lobe. More recently, alternative approaches including lung-sparing resections (LSR), such as wedge or non-anatomic resections and segmentectomy, have been suggested. In asymptomatic CPAM early surgical resection is often shown to reduce infection and malignancy development. We describe two patients who were diagnosed with CPAM when being evaluated for respiratory tract infection. Patient 1 (P1) was a two-month-old infant weighing 4 kg with glucose-6-phosphate dehydrogenase (G6PD) deficiency and Patient 2 (P2) was a toddler aged one year, nine months weighing 9 kg. P1 underwent LSR for the CPAM diagnosed in the left upper lobe of the lung with conventional mechanical ventilation whilst right upper lobectomy was performed in P2 using one/single lung ventilation. In both cases, LSR and right upper lobectomy led to an uneventful postoperative recovery with no complications reported.

Abstract
Pediatric patients undergoing reoperative cardiac surgery after a previous sternotomy face a higher degree of surgical complexity compared to those undergoing initial procedures. They have higher intraoperative and postoperative risks. The increased risk of surgery is due to preoperative patient factors and intraoperative technical challenges. Redo-pediatric cardiac surgery is a common event in almost every pediatric cardiac surgeon's professional life. Redo-surgery is almost inevitable in patients who have multi-stage repair of congenital heart surgeries and biological valves at a young age, and often in those having valve repair in rheumatic disease. So, being familiar with the pitfalls and precautions to be taken is of crucial importance. In general, the patients presenting for repeat procedures are sicker, older, and have more comorbid conditions. The dissection is always rendered difficult by adhesions, scarring, and previous graft placements. Hence, prolonged dissection time, intraoperative injuries to heart chambers, great vessels, and grafts, increased bleeding, and poorer cardiac function result in higher morbidity and mortality in such subsets of patients. The outcome is worse with emergency redo-cardiac surgeries.

Abstract
Diaphragmatic paralysis (DP), whether unilateral or bilateral, often leads to extended recovery and more severe complications, particularly in neonates and infants undergoing congenital heart surgery. This condition's impact is most pronounced after single-ventricle palliative procedures. Tracheostomy prevalence is rising in pediatric patients with congenital heart disease (CHD) despite its association with high resource utilization and in-hospital mortality. This study examines the reported incidence of diaphragmatic paralysis and timing of tracheostomy in pediatric patients undergoing surgery for congenital heart disease in the literature and a retrospective analysis of cases in our institution between 2018 and 2023, offering insights for prospective management. An electronic search of PubMed databases retrieved 10 studies on pediatric tracheostomy and 11 studies on DP. Our retrospective analysis included 15 patients, of whom 10 underwent tracheostomy, four underwent diaphragmatic plication, and one underwent both. Postoperative tracheostomy had an 11.8% mortality rate in our systematic review, rising to 40% in our observational study. Diaphragm repair and early diagnosis can reduce morbidity, prevent complications, and improve patients' quality of life.

Abstract
Background and objective Complex congenital heart diseases (CHDs), such as the tetralogy of Fallot (TOF), often warrant reconstruction and augmentation of the right ventricular outflow tract (RVOT). This procedure requires the use of both synthetic and natural materials. However, finding the ideal material for tissue implants can be challenging. Biological materials often face issues such as tissue degeneration, calcium deposition, antigenicity, rejection, shrinkage, and fibrosis. These issues can lead to complications such as stenosis and insufficiency, potentially requiring early reoperations. In light of this, this study aimed to investigate the effectiveness of the Invengenx® bovine patch for RVOT reconstruction and augmentation. Methods This was a retrospective observational study conducted among eight children who underwent TOF correction cardiac surgery. Their demographic and clinical characteristics, intraoperative findings, and postoperative follow-up results at six months were collected from the hospital patient database. Results There were no deaths or complications in this study. We observed a significant reduction in the gradient across the pulmonary valve and the outflow tract at six months post-procedure. The analysis demonstrated that the Invengenx® bovine patch was successful and did not lead to any complications. Conclusions This study demonstrates the safety and efficacy of this engineered bovine pericardial patch (Invengenx®) as a cardiovascular substitute for surgical repair of both simple and more complex congenital cardiac defects.

Abstract
Brain relaxation is an important requirement in intracranial neurosurgical procedures and optimal brain relaxation improves the operating conditions. Optic nerve sheath diameter (ONSD) is a non-invasive bedside surrogate marker of intracranial pressure (ICP) status. Elevated ICP is often associated with marked autonomic dysfunction. There is no standard measure to predict intraoperative brain condition non-invasively, considering both anatomical displacement and physiological effects due to raised ICP and brain oedema. This study was aimed to determine the usefulness of heart rate variability (HRV) parameters and ONSD preoperatively in predicting intraoperative brain relaxation in patients with supratentorial tumors undergoing surgery.This prospective observational study was conducted in a tertiary care centre. 58 patients with supratentorial brain tumors undergoing elective surgery were studied. Preoperative clinical presentation, computed tomography (CT) findings, ONSD and HRV parameters were assessed in determining intraoperative brain condition. Intraoperative hemodynamic parameters and brain relaxation score after craniotomy were studied. There was significant difference in CT grade, ONSD and HRV parameters in patients between lax and tight brain. A receiver operating curve was constructed to determine the cut off to predict intraoperative brain bulge. A CT grade more than 2, ONSD of greater than 0.63 cms and ratio of low frequency to high ratio (LF/HF) of more than 1.8 were good predictors of brain bulge. The changes in ONSD and HRV parameters, with the CT findings can be used as surrogate markers of increased ICP to help predict intraoperative brain condition.

Abstract
Ag-doped TiO2 and Ag-doped TiO2 loaded cassava stem activated carbon (Ag: TiO2/CSAC) were prepared by sol-gel method and are labelled as AT and AT/CSAC respectively. XRD results confirmed that the anatase-TiO2 and crystalline size are decreased (12.37 nm) through the silver doping and cassava stem activated carbon loading. UV-Vis showed that the AT/CSAC makes a red shift from the absorption edge compared to pure and AT samples and then the band gap is reduced (2.81 eV). The increased surface area (238.51 m2/g) of the AT/CSAC sample through the Ag and CSAC, respectively. The consequences point out that the highest photodegradation efficiency (98.08%) of the TiO2 upon silver doping and cassava stem activated carbon loading samples were brilliant green (BG) under sunlight irradiation.

Abstract
Background Hypotension is one of the most common complications following induction of general anesthesia. Preemptive diagnosis and correcting the hypovolemic status can reduce the incidence of post-induction hypotension. However, an association between preoperative volume status and severity of post-induction hypotension has not been established in neurosurgical patients. We hypothesized that preoperative ultrasonographic assessment of intravascular volume status can be used to predict post-induction hypotension in neurosurgical patients. Our study objective was to establish the relationship between pre-induction maximum inferior vena cava (IVC) diameter, collapsibility index (CI), and post-induction reduction in mean arterial blood pressure in neurosurgical patients. Materials and Methods A prospective observational study was conducted including 100 patients undergoing elective intracranial surgeries. IVC assessment was done before induction of general anesthesia. Receiver operating characteristic (ROC) curve analysis was used to determine the cutoff values of maximum and minimum IVC diameter (IVCDmax and IVCDmin, respectively) and CI for prediction of hypotension. Results Post-induction hypotension was observed in 41% patients. Patients with small IVCDmax and higher CI% developed hypotension. The areas under the ROC curve (AUCs) were 0.64 (0.53-0.75) for IVCDmax and 0.69 (0.59-0.80) for IVCDmin. The optimal cutoff values were1.38 cm for IVCDmax and 0.94 cm for IVCDmin. The AUC for CI was 0.65 (0.54-0.77) and the optimal cutoff value was 37.5%. Conclusion Pre-induction IVC assessment with ultrasound is a reliable method to predict post-induction hypotension resulting from hypovolemia in neurosurgical patients.

Abstract
Backgroud and Aims: Conference presentations provide an opportunity to rapidly share findings of new research despite limitations of details and reach. Earlier studies have examined publication rates of conference presentations in anesthesia. However, conversion rate of neuroanesthesia meeting presentations to publications is unknown. We assessed the publication rate of neuroanesthesia conference presentations from India over a 5-year period and identified factors contributing to subsequent publications. Material and Methods: Conference abstracts of the Indian Society of Neuroanaesthesiology and Critical Care (ISNACC) from 2014 to 2018 were studied with regard to conversion to full-length publications. Details of presentations were obtained from abstracts published in the journal of ISNACC and details of publications were collected by searching Google and PubMed using title and author details. Results: Only 17.5% (40/229) of the abstracts presented at ISNACC conferences over a 5-year period resulted in subsequent full-text publications in peer-reviewed journals. Prospective cohort studies (OR [95% CI] 2.84 [1.05–8.56], P = 0.048), randomized trials (OR [95% CI] 2.69 [1.04 to 7.9], P = 0.053), and abstracts from public institutions (OR [95% CI] 3.44 [1.4 to 10.42], P = 0.014) were significantly associated with publications after conference presentations. Conclusion: The conversion rate of conference presentations of neuroanesthesia society of India into journal publications is significantly low. There is need for neuroanesthesia community of India to work together to improve the translation of presentations into publications.

Abstract
AbstractFever is considered a protective response having multitude of benefits in terms of enhancing resistance to infection, recruiting cytokines to the injured tissue, and promoting healing. In terms of an injured brain, this becomes a double-edged sword triggering an inflammatory cascade resulting in secondary brain injury. It is important to identify the etiology so that corrective measures can be taken. Here we report a case of persistent fever in a patient with Guillain-Barré syndrome, which was probably due to heparin. This is the first report of heparin-induced fever in a neurocritical care setting and third report overall.

Abstract
BACKGROUND Perioperative pain assessment and management in neurosurgical patients varies widely across the globe. There is lack of data from developing world regarding practices of pain assessment and management in neurosurgical population. This survey aimed to capture practices and perceptions regarding perioperative pain assessment and management in neurosurgical patients among anesthesiologists who are members of the Indian Society of Neuroanaesthesiology and Critical Care (ISNACC) and evaluated if hospital and pain characteristics predicted the use of structured pain assessment protocol and use of opioids for postoperative pain management. METHODS A 26-item English language questionnaire was administered to members of ISNACC using Kwiksurveys platform after ethics committee approval. Our outcome measures were adoption of structured protocol for pain assessment and opioid usage for postoperative pain management. RESULTS The response rate for our survey was 55.15% (289/524). One hundred eighteen (41%) responders informed that their hospital setup had a structured pain protocol while 43 (15%) responders reported using opioids for postoperative pain management. Predictors of the use of structured pain protocol were private setup (odds ratio [OR] 2.64; 95% confidence interval [CI] 1.52-4.59; P = .001), higher pain intensity (OR 0.37; 95% CI 0.21-0.64; P < .001) and use of pain scale (OR 7.94; 95% CI 3.99-15.81; P < .001) while availability of structured pain protocol (OR 2.04; 95% CI 1.02-4.05; P = .043) was the only significant variable for postoperative opioid use. CONCLUSIONS Less than half of the Indian neuroanesthesiologists who are members of ISNACC use structured protocol for pain assessment and very few use opioids for postoperative pain management in neurosurgical patients.

Abstract
Introduction The optimal time to discontinue patients from mechanical ventilation is critical as premature discontinuation as well as delayed weaning can result in complications. The literature on diaphragm function assessment during the weaning process in the intriguing subpopulation of critically ill neuromuscular disease patients is lacking. Methods Patients with neuromuscular diseases, on mechanical ventilation for more than 7 days, and who were ready for weaning were studied. During multiple T-piece trials over days, diaphragm function using ultrasound and diaphragm electrical activity (Edi peaks using NAVA catheter) was measured every 30 min till a successful 2 h weaning. Results A total of 18 patients were screened for eligibility over 5-month period and eight patients fulfilled the inclusion criteria. Sixty-three data points in these 8 subjects were available for analysis. A successful breathing trial was predicted by Edi reduction (1.22 μV for every 30 min increase in weaning duration; 0.69 μV for every day of weaning) and increase in diaphragm excursion (2.81 mm for every 30 min increase in weaning duration; 2.18 mm for every day of weaning). Conclusion The Edi and diaphragm excursion changes can be used as additional objective tools in the decision-making of the weaning trials in neuromuscular disease.

Abstract
Atlantoaxial dislocation (AAD) poses a significant challenge in terms of positioning and surgical fixation as there is increased risk of cord compression and ischemia. Intraoperative neuromonitoring (IONM) provides a useful tool to identify impending position-related dysfunction. Here we demonstrate the utility of using transcranial motor evoked potential (Tc-MEP) to identify and treat suboptimal positioning in a 13-year-old patient with AAD and Arnold-Chiari malformation.

Abstract
Background
Brain abscess is a rare neurological complication in patients with congenital cyanotic heart disease (CCHD). Perioperative complications are high in patients with CCHD. We evaluated incidence of and risk factors for perioperative complications and their impact on clinical outcomes in patients with CCHD undergoing brain abscess surgery with monitored anesthesia care (MAC) or general anesthesia (GA).
Methods
In this single-center retrospective cohort study, data were collected from consecutive patients with CCHD who presented with brain abscess and underwent surgery from January 2006 to December 2018. Data regarding demographics, type of CCHD, signs and symptoms of brain abscess and CCHD, type and duration of surgery, details of anesthesia, perioperative complications, and clinical outcomes were collected. Chi-square test was used to analyze nonparametric data and student
t
-test for parametric data.
Results
Of the 402 patients with brain abscess, data of 34 patients with CCHD who underwent brain abscess surgery were analyzed. The mean age at presentation of brain abscess was 15.8 ± 10.8 years and duration of symptoms was 17.3 ± 15.5 days. The incidence of perioperative complications was 82.4% (28/34 patients). Seven patients (20.6%) developed perioperative cyanotic spells which led to cardiac arrest in 5 patients (14.7%) and death in 2 patients (5.9%). Patients on cardiac medications and with high heart rate had higher incidence of cyanotic spells and mortality. Technique of anesthesia did not affect cardiac and neurological outcome.
Conclusions
Perioperative complications are high after brain abscess surgery in patients with CCHD. Perioperative characteristics and outcomes were similar with MAC and GA techniques.

Abstract
Objective Thrombocytopenia in dengue fever (DF) is a well-known complication in both adults and pediatric subjects. Management of DF primarily includes symptomatic and intensive supportive care. There are studies available on the efficacy and safety of Carica papaya leaf extract (CPLE) in adult patients with DF. However, there are no published studies available on the efficacy and safety of CPLE in the pediatric age group. Hence, this study was conducted. Methodology A prospective, open-label, randomized controlled study was conducted in subjects aged between 1 and 12 years having thrombocytopenia associated with DF (NS-1 antigen positive) or dengue hemorrhagic fever (DHF) grades I and II. All participants were randomized into the intervention group (n =147, CPLE syrup + standard therapy) and the control group (n=147, received only standard therapy). All subjects were followed up daily for 5 days with monitoring of blood counts. Results A total of 285 subjects were finally evaluated for efficacy, and nine dropped out (seven in the control group and two in the intervention group). However, all 294 subjects were evaluated for safety. CPLE (Caripill) syrup increased the platelet count significantly compared to the control group (P<0.05). In the intervention group, the platelet count increased from day 3 onward: platelet count on day 3 (mean platelet count =89,739.31, P=0.030), day 4 (mean platelet count =120,788.96, P=0.019), and day 5 (mean platelet count =168,922.75 P=0.023). Two children complained of nausea in the intervention group. Overall, Caripill syrup was well tolerated. Conclusion CPLE syrup significantly increases the platelet count in pediatric DF patients and is well tolerated.

Abstract
Background and aims To determine the incidence of upper and lower limb deep vein thrombosis (DVT) using ultrasonography (USG) in adult patients admitted to neuro-medical and neurosurgical intensive care unit (ICU). Materials and methods In this prospective observational study, patients admitted to the medical and surgical neuro-ICU and remained in the ICU for more than 48 hours were recruited. All patients were clinically examined for DVT. Basilic and axillary veins in the upper limbs and popliteal and femoral veins in the lower limbs were screened for DVT using USG. USG examination was performed on the day of admission to ICU and thereafter every 3rd day till discharge from ICU or death. Intermittent pneumatic compression (IPC) stockings were applied to the lower limbs to all the patients in both ICUs. Unfractionated heparin (UFH) was given subcutaneously to neuromedical ICU patients, while in surgical ICU, it was left to the discretion of the neurosurgeons. Results A total of 130 adult patients were admitted to the ICU during the 8 month study period. Thirty patients were excluded and the remaining 98 patients’ (38 in medical and 60 in surgical ICU) data were analyzed. None of the 38 medical ICU patients developed DVT, while in neurosurgical ICU, 4 out of 60 patients developed DVT. Conclusion A combination of UFH and IPC stockings were effective in minimizing the DVT in neuromedical ICU patients. In surgical patients, through IPC stockings were effective, UFH can be considered for patients with intracranial malignancy.

Abstract
Background The use of intravenous (IV) cannulas is an integral part of patient care in hospitals. These intravenous cannulas are a potential route for microorganisms to enter the blood stream resulting in a variety of local or systemic infections. Studies showing the actual prevalence of colonization of peripheral IV cannulas and its role in BSI are lacking. Hence, this study was aimed to estimate the prevalence of colonization of the injection ports of peripheral IV cannulas. Methods This cross sectional study was conducted on patients admitted in ICU and wards in an 800 bedded tertiary care hospital. Swabs were taken from lumens of peripheral IV cannulas and cultured. Patient demographic data and practices followed for maintenance of IV line were noted. Results A total of 196 injection port samples were taken, out of which 11 tested positive for microbial growth (5.61%). Staphylococcus aureus was the predominant organism contributing 64% of the microbial growth. A significant association was seen between presence of local signs, old age and positive cultures. Flushing IV cannula every 6 h was associated with negative cultures. Conclusion Peripheral IV cannulation has significant potential for microbial contamination and is largely ignored. Most of the risk factors associated with growth of microorganisms in the injection ports of peripheral intravenous cannulas (which has a potential to cause catheter-related blood stream infections) can be prevented by improving protocols for management. To prevent infection from occurring, practitioners should be educated and trained about the care and management of IV.

Abstract
OBJECTIVE Current antiepileptic drugs (AEDs) have several shortcomings. For example, they fail to control seizures in 30% of patients. Hence, there is a need to identify new AEDs. Drug repurposing is the discovery of new indications for approved drugs. This drug "recycling" offers the potential of significant savings in the time and cost of drug development. Many drugs licensed for other indications exhibit antiepileptic efficacy in animal models. Our aim was to create a database of "prescribable" drugs, approved for other conditions, with published evidence of efficacy in animal models of epilepsy, and to collate data that would assist in choosing the most promising candidates for drug repurposing. METHODS The database was created by the following: (1) computational literature-mining using novel software that identifies Medline abstracts containing the name of a prescribable drug, a rodent model of epilepsy, and a phrase indicating seizure reduction; then (2) crowdsourced manual curation of the identified abstracts. RESULTS The final database includes 173 drugs and 500 abstracts. It is made freely available at www.liverpool.ac.uk/D3RE/PDE3. The database is reliable: 94% of the included drugs have corroborative evidence of efficacy in animal models (for example, evidence from multiple independent studies). The database includes many drugs that are appealing candidates for repurposing, as they are widely accepted by prescribers and patients-the database includes half of the 20 most commonly prescribed drugs in England-and they target many proteins involved in epilepsy but not targeted by current AEDs. It is important to note that the drugs are of potential relevance to human epilepsy-the database is highly enriched with drugs that target proteins of known causal human epilepsy genes (Fisher's exact test P-value < 3 × 10-5 ). We present data to help prioritize the most promising candidates for repurposing from the database. SIGNIFICANCE The PDE3 database is an important new resource for drug repurposing research in epilepsy.

Abstract
Background Pain associated with laparoscopic cholecystectomy is most severe during the first 24 h and the port sites are the most painful. Recent multimodal approaches target incisional pain instead of visceral pain which has led to the emergence of abdominal fascial plane blocks. This study embraces a novel combination of two independently effective fascial plane blocks, namely rectus sheath block and subcostal transversus abdominis plane (TAP) block to alleviate postoperative pain. Study Objective The aim is to evaluate the effectiveness of the combination of rectus sheath block and subcostal TAP block, to compare its efficacy with that of subcostal TAP block alone and with conventional port site infiltration (PSI) in alleviating postoperative pain in patients undergoing laparoscopic cholecystectomy. Methodology This prospective, randomized control, pilot study included 61 patients scheduled for elective laparoscopic cholecystectomy and distributed among three groups, namely Group 1: Combined subcostal TAP block with rectus sheath block (n = 20); Group 2: Oblique subcostal TAP block alone (n = 21); and Group 3: PSI group as an active control (n = 20). Results Combined group had significantly lower pain scores, higher satisfaction scores, and reduced rescue analgesia both in early and late postoperative periods than the conventional PSI group. Conclusion Ultrasound-guided combined fascial plane blocks is a novel intervention in pain management of patients undergoing laparoscopic cholecystectomy and should become the standard of care.

Abstract
BACKGROUND Postoperative pain is thought to be the single most important factor leading to ineffective ventilation and impaired secretion clearance after thoracic trauma. Effective pain relief can be provided by thoracic epidural analgesia but may have side effects or contraindications. Paravertebral block is an effective alternative method without the side effects of a thoracic epidural. We did this study to compare efficacy of thoracic epidural and paravertebral block in providing analgesia to thoracic trauma patients. METHODS After ethical clearance, 50 patients who had thoracic trauma were randomized into two groups. One was a thoracic epidural group (25), and second was a paravertebral group (25). Both groups received 10 ml of bolus of plain 0.125% bupivacaine and a continuous infusion of 0.25% bupivacaine at the rate of 0.1 ml/kg/h for 24 h. Assessment of pain, hemodynamic parameters, and spirometric measurements of pulmonary function were done before and after procedure. Visual analog scale (VAS) scores were accepted as main outcome of the study and taken for power analysis. RESULTS There was significant decrease in postoperative pain in both the groups as measured by VAS score. However, the degree of pain relief between the groups was comparable. There was a significant improvement in pulmonary function tests in both the groups post-procedure. The change in amount of inflammatory markers between both the groups was not significantly different. CONCLUSION Paravertebral block for analgesia is comparable to thoracic epidural in thoracic trauma patients and is associated with fewer side effects.

Abstract
Glomus tumours involving bronchus are rare. Surgical resection is the treatment of choice for this tumour, with excellent prognosis. The nature and location of tumour pose a significant challenge for perioperative anaesthetic management. However, there is a paucity of case reports on anaesthetic risks involved in case of a bronchial glomus tumour. We present a case of glomus tumour involving left main stem bronchus, subjected to bronchial sleeve resection. The various anaesthetic implications of this tumour type and airway management with right double lumen tube are discussed.

Abstract
In the cation of the title salt, C6H7N2O2+·C7H7O3S−, the benzene ring makes a dihedral angle of 10.2 (2)° with the nitro group. In the crystal, the cations and anions are linked by weak N—H⋯O hydrogen bonds, forming a layer parallel to the ac plane. A weak C—H⋯O interaction and π–π interactions [centroid–centroid distances of 3.738 (3) and 3.748 (3) Å] also observed within the layer.

Abstract
Prevalence of infectious bursal disease (IBD) among chickens in different parts of Tamil Nadu, India, has been studied by collection of bursal samples from suspected flocks and by performing reverse transcription-polymerase chain reaction (RT-PCR) for amplification of a specific product of 474 bp from the variable region of the VP2 gene. Among 53 bursal samples examined by RT-PCR, 40 showed a positive reaction. The amplified products were subjected to nucleotide sequencing and the obtained sequences were compared with those of IBD virus (IBDV) vaccine strain Georgia, the classical virulent strain 52/70 and the very virulent Japanese OKYM strain. Nucleotide homology data indicated that all the Tamil Nadu isolates showed homology ranging from 91 to 99.6% among themselves. When compared with the very virulent Japanese OKYM strain, four isolates grouped with that strain. Majority of the isolates clustered with the very the virulent OKYM strain as evident from phylogenetic analysis performed using the MEGA program. Comparison of the deduced amino acid sequences of IBDV isolates with those of the vaccine strain Georgia, the classical virulent strain 52/70 and the very virulent strain OKYM also revealed the presence of conserved serine-rich heptapeptide sequence in most of the isolates. Results of this study indicate that majority of the IBDV isolates are very virulent, which is evident from heavy mortality that has been reported in few flocks of poultry in spite of regular vaccination.
