Unifocal Tubercular Osteomyelitis of Ulna Diaphysis in a Child: A Case Report.

Introduction: Osteoarticular tuberculosis (OATB) contributes to around 10% of extrapulmonary tuberculosis of which the spine is the most common site. Isolated involvement of ulna diaphysis is extremely rare. We present a case of unifocal tuberculous osteomyelitis of ulna diaphysis in a 3 -year-old male child and highlight its resemblance with musculoskeletal tumors and stress the importance of GeneXpert mycobacterium tuberculosis (MTB)/resistance to rifampicin (RIF) in the diagnosis of OATB. Case Report: A mother of a 2-year-old male child incidentally noticed that her son complained of left forearm pain. She was not sure of any fall or trauma to the forearm. No history of fever or other constitutional symptoms was present. Clinical examination was uneventful except for local tenderness in over the dorsomedial aspect of the left mid forearm. A plain radiograph revealed an oval solitary lytic lesion over distal one-third ulna diaphysis. A needle biopsy was done after clinical, hematological, and radiological evaluation, and finally, GeneXpert detected tuberculosis without RIF. No further tests were required and the child was started on antitubercular therapy (ATT) which resulted in complete healing without any symptoms. Conclusion: The authors conclude that it is therefore essential to consider tuberculosis in the differential diagnosis while evaluating a lytic bone lesion. Where possible, all patients should have a biopsy of the lesion and provide a specimen for GeneXpert MTB/RIF to confirm the diagnosis and drug susceptibility testing.

Osteoblastoma of the frontal sinus: A rare case presenting with seizures and pneumocephalus.

Key Clinical Message: Osteoblastoma of the frontal sinus, although rare, can manifest with seizures and pneumocephalus, underscoring the importance of thorough evaluation and complete surgical excision to prevent serious complications and ensure optimal patient outcomes. Abstract: Osteoblastoma is an infrequent bone tumor, with origins typically in the vertebrae and long bones. While craniofacial involvement is rare, it may occur in regions such as the paranasal sinuses. We present a case of osteoblastoma located in the frontal sinus, an exceptionally uncommon site, resulting in seizures secondary to pneumocephalus. A 21-year-old male presented with a generalized tonic-clonic seizure and postictal confusion. Imaging studies revealed a well-defined lesion in the left frontal sinus causing cortical breach, destruction of the posterior wall, and pneumocephalus. A total surgical excision was performed through bifrontal craniotomy. Histopathological analysis confirmed the diagnosis of osteoblastoma. Postoperative recovery was uneventful, with a follow-up CT scan showing complete lesion excision. Osteoblastomas, especially in the cranial sinuses, are rare entities that may present asymptomatically but can lead to severe complications. The risk of recurrence underscores the importance of complete surgical resection for optimal patient outcomes.

Impairments in pulmonary functions in paediatric spinal tuberculosis: a cross-sectional study.

PURPOSE: This study aimed to investigate the impact of vertebral column destruction and kyphotic deformity due to spinal tuberculosis on pulmonary functions in paediatric patients. METHODS: A cross-sectional study was conducted, involving 30 patients diagnosed with healed spinal tuberculosis, aged 7-18 years. Detailed radiographic measurements, including the level of involvement, kyphosis angle, Spinal Deformity Index (SDI), and drug-resistance status, were compared with various pulmonary function parameters. RESULTS: The mean age of the study group was 12.8 ± 2.7 years (range 7-17 years), consisting of 11 males and 19 females. Fourteen patients were managed conservatively and 16 were managed operatively. The mean SDI was 5.2 ± 4.7. The mean kyphotic angle was 31.3° ± 25.3. The average number of involved vertebrae was 2.6 ± 1.5. Pulmonary functions were classified as restrictive in 24 patients, normal in 4 patients, obstructive in 1 patient, and mixed in 1 patient. Multidrug-resistant tuberculosis (MDR-TB) was detected in 5 (16.7%) patients, while the remaining 25 (83.3%) patients were sensitive to conventional antitubercular drugs. The correlation coefficients between the percentage reduction in forced vital capacity (FVC) and kyphosis angle, SDI, and number of vertebrae were 0.4 (p = 0.026), 0.4 (p = 0.028), and 0.19 (p = 0.295), respectively. The mean percentage reduction in FVC and total lung capacity (TLC) were 35.8 ± 15.7 and 6.2 ± 2.3, respectively. No significant association was observed between pulmonary functions and drug sensitivity status (p = 0.074). CONCLUSIONS: Paediatric spinal tuberculosis can lead to thoracic insufficiency due to progressive destruction and shortening of the spinal column, spinal growth inhibition, and kyphotic deformity. Management of these cases should focus on promoting normal lung development while ensuring disease resolution and deformity correction. Further research should explore growth conserving or growth guiding systems to address or prevent growth retardation and simultaneously provide spinal stabilization.

Tibial lengthening for massive distal femoral bone loss.

A man in his 30s was involved in a road traffic accident (RTA) and sustained a grade-IIIA distal femur fracture with acute loss of distal two-third of the femur. Initially, damage control surgery was done by an external fixator application. Later, staged limb reconstruction surgery was undertaken as a definitive procedure that involved bifocal distraction osteogenesis involving the proximal tibia and femur along with docking of the corticotomised femoral fragment onto the tibial plateau to achieve knee arthrodesis. The tibial and femoral regenerate together measured 25.8 cm at the end of distraction phase leaving behind a limb length discrepancy of 5 cm. Acute traumatic large bone loss is a rare presentation and is beset with unique management challenges. Limb reconstruction surgery (LRS) with LRS system provides flexibility to tackle individual case-based scenarios and helps achieve limb length, maintain alignment and restore function.

Rapid metabolic fingerprinting with the aid of chemometric models to identify authenticity of natural medicines: Turmeric, Ocimum, and Withania somnifera study.

Herbal medicines are popular natural medicines that have been used for decades. The use of alternative medicines continues to expand rapidly across the world. The World Health Organization suggests that quality assessment of natural medicines is essential for any therapeutic or health care applications, as their therapeutic potential varies between different geographic origins, plant species, and varieties. Classification of herbal medicines based on a limited number of secondary metabolites is not an ideal approach. Their quality should be considered based on a complete metabolic profile, as their pharmacological activity is not due to a few specific secondary metabolites but rather a larger group of bioactive compounds. A holistic and integrative approach using rapid and nondestructive analytical strategies for the screening of herbal medicines is required for robust characterization. In this study, a rapid and effective quality assessment system for geographical traceability, species, and variety-specific authenticity of the widely used natural medicines turmeric, Ocimum, and Withania somnifera was investigated using Fourier transform near-infrared (FT-NIR) spectroscopy-based metabolic fingerprinting. Four different geographical origins of turmeric, five different Ocimum species, and three different varieties of roots and leaves of Withania somnifera were studied with the aid of machine learning approaches. Extremely good discrimination (R2 > 0.98, Q2 > 0.97, and accuracy = 1.0) with sensitivity and specificity of 100% was achieved using this metabolic fingerprinting strategy. Our study demonstrated that FT-NIR-based rapid metabolic fingerprinting can be used as a robust analytical method to authenticate several important medicinal herbs.

Impact of anthropogenic and land use pattern change on spatio-temporal variations of groundwater quality in Odisha, India.

The groundwater physicochemical parameters were studied to understand their spatiotemporal variations and groundwater quality, using the statistical and entropy weights methods. Out of ten parameters that were considered, F-, TDS, and Cl- appear to be the major contributors influencing the quality of groundwater. The Principal Component Analysis (PC1, PC2) indicates that the majority of ions are derived from both natural and anthropogenic sources. Studies of saturation indices of gypsum, Halite, dolomite, and calcite indicate that dissolution of these salts also affects groundwater salinization. In coastal areas, a few of the water samples also appear to be contaminated by the mixing of seawater. The entropy weights, which are free from subjective biases were used to estimate the water quality index. The entropy-based water quality index (EWQI) varies from excellent to good quality for the year 2012-13, and appears to degrade after 2015 onwards. For the year 2018-19 and 2021-22, 71.42% and 68.42% of the study areas show excellent water quality, followed by 25.33% and 24.33% (good), 2.54% and 3.54% (average), 0.7% and 3.7% study area shows as poor quality respectively. The groundwater quality, particularly in the western, central, northern, and eastern parts of the region, appears to be average, poor, and very poor in several small patches, respectively. Industrial developments, mining activities, irrigation, changing land use patterns, agricultural activities, and increased anthropogenic activities may be contributing to the degradation of the water quality.

Mycorrhizae set the stage for plants to produce a higher production of biomolecules and stress-related metabolites: a sustainable alternative of agrochemicals to enhance the quality and yield of beetroot (Beta vulgaris L.).

Population explosions, environmental deprivation, and industrial expansion led to an imbalanced agricultural system. Non-judicial uses of agrochemicals have decreased agrodiversity, degraded agroecosystems, and increased the cost of farming. In this scenario, a sustainable agriculture system could play a crucial role; however, it needs rigorous study to understand the biological interfaces within agroecosystems. Among the various biological components with respect to agriculture, mycorrhizae could be a potential candidate. Most agricultural crops are symbiotic with arbuscular mycorrhizal fungi (AMF). In this study, beetroot has been chose to study the effect of different AMFs on various parameters such as morphological traits, biochemical attributes, and gene expression analysis (ALDH7B4 and ALDH3I1). The AMF Gm-Funneliformis mosseae (Glomus mosseae), Acaulospora laevis, and GG-Gigaspora gigantean were taken as treatments to study the effect on the above-mentioned parameters in beetroot. We observed that among all the possible combinations of mycorrhizae, Gm+Al+GG performed best, and the Al-alone treatment was found to be a poor performer with respect to all the studied parameters. This study concluded that the more the combinations of mycorrhizae, the better the results will be. However, the phenomenon depends on the receptivity, infectivity, and past nutrient profile of the soil.

Comprehensive Metabolomic Fingerprinting Combined with Chemometrics Identifies Species- and Variety-Specific Variation of Medicinal Herbs: An Ocimum Study.

Identification of plant species is a crucial process in natural products. Ocimum, often referred to as the queen of herbs, is one of the most versatile and globally used medicinal herbs for various health benefits due to it having a wide variety of pharmacological activities. Despite there being significant global demand for this medicinal herb, rapid and comprehensive metabolomic fingerprinting approaches for species- and variety-specific classification are limited. In this study, metabolomic fingerprinting of five Ocimum species (Ocimum basilicum L., Ocimum sanctum L., Ocimum africanum Lour., Ocimum kilimandscharicum Gurke., and Hybrid Tulsi) and their varieties was performed using LC-MS, GC-MS, and the rapid fingerprinting approach FT-NIR combined with chemometrics. The aim was to distinguish the species- and variety-specific variation with a view toward developing a quality assessment of Ocimum species. Discrimination of species and varieties was achieved using principal component analysis (PCA), partial least squares discriminate analysis (PLS-DA), data-driven soft independent modelling of class analogy (DD-SIMCA), random forest, and K-nearest neighbours with specificity of 98% and sensitivity of 99%. Phenolics and flavonoids were found to be major contributing markers for species-specific variation. The present study established comprehensive metabolomic fingerprinting consisting of rapid screening and confirmatory approaches as a highly efficient means to identify the species and variety of Ocimum, being able to be applied for the quality assessment of other natural medicinal herbs.

Suitability of the Lower Ganga basin groundwater for irrigation, using hydrogeochemical parameters and land-use dynamics.

The northern Ganga basin is one of the most densely populated basins in the world. Most agricultural and industrial contaminants drained in the river length are likely to be accumulated in the lower part of the Ganga basin. In this study, we have used ten parameters obtained from 495 sampling locations, besides using long-term climate data (GLDAS_NOAH025_M) to understand the irrigation suitability using the TOPSIS model. Multi-criteria decision making (MCDM) model using TOPSIS has been used to make the best choices from the available finite number of alternatives based on their ranking. The entropy weights for the irrigation suitability parameters such as electrical conductivity (Ec), sodium adsorption ratio (SAR), magnesium hardness (MH), sodium percent (Na%), total hardness (TH), Kelly's ratio (KR), permeability index (PI), chloride concentration (Cl-), groundwater level fluctuation (GWLF), and the Lang factor (Df) are found to be 0.08, 0.14, 0.02, 0.02, 0.04, 0.08, 0.01, 0.32, 0.29, and 0.01, respectively. We find that SAR, Cl-, and GWLF control the water quality for irrigation in the Lower Ganga basin since these parameters have relatively higher entropy weights (more than 0.10). The results obtained from the computed performance index or the closeness coefficient show that the area percent having very good and good groundwater quality for irrigation in the Lower Ganga basin is 77.03% and 22.97% respectively. The land-use change dynamics for the between 2000 and 2015 estimated using the transition matrix shows a positive percentage change for settlement (133.50%), wetland (35.04%), and bare area (0.98%); however, several other classes such as the agriculture (- 0.85%), forest (- 0.49%), grassland (- 14.38%), sparse vegetation (- 11.39%), and water (- 4.12%) show a decreasing trend. The highest amount of percentage change was observed in settlement areas which were contributed by other land-use classes such as agriculture (694.43 km2), water (41.61 km2), forest (16.77 km2), and grassland (1.86 km2). The results may be useful to the concerned organization for the proper planning and management of water resource for sustainable development.

Outcome of Joint Aspiration in Acute Knee Haemarthrosis in a Haemophilic Joint: A Prospective Randomised Controlled Trial in 120 Patients in a Tertiary Haemophilia Care Centre.

Background: Bleeding into the joints cause major morbidity in haemophilia patients. The clinical hallmark of haemophilia is haemarthrosis especially in knee, ankle and elbow joint. Current literature suggests that aspiration of an acute haemarthrosis in haemophilia may lead to further bleeding and prevent tamponade effect. But the rehabilitation gets delayed, leading to joint stiffness and the function gets deteriorated. This study was done to evaluate the efficacy of joint aspiration in the management of acute knee haemarthrosis, with regard to pain relief and functional outcome. Materials and Methods: This is a prospective, randomised controlled trial in a tertiary care haemophilia treatment centre comprising 120 haemophilic patients with unilateral acute knee haemarthrosis. Factor level was checked and appropriate factor replacement [40%] was done. The patients were randomly allocated in two groups: Group A and Group B, each consisting of 60 patients. All patients received ice application, limb immobilisation, analgesics, physiotherapy and compression bandage as the routine primary management. In addition, study Group A also received therapeutic aspiration of the knee joint at initial presentation, after the first factor infusion. All patients were clinically evaluated for pain in terms of Visual Analogue Scale (VAS score) and function in terms of Haemophilic Joint Health Score [HJHS], before and at 4 h, 48 h and 7 days after initial factor administration. Results: All patients showed therapeutic improvement in terms of a declining trend in VAS and HJHS scores. Pain relief (VAS Score) in Group A, was found to be significantly better compared to Group B at the end of 4 h [4.80 ± 0.49 vs 6.54 ± 1.05; p < 0.001], 48 h [2.48 ± 0.50 vs 3.30 ± 0.46; p < 0.001] and 7 days [1.16 ± 0.37 vs 1.70 ± 0.46; p < 0.001]. Functional improvement (HJHS Score) in Group A, was found to be significantly better compared to Group B as well at the end of 4 h [11.24 ± 0.77 vs 14.52 ± 0.61; p < 0.001], 48 h [7.24 ± 0.65 vs 11.28 ± 0.64; p < 0.001] and 7 days [2.36 ± 0.48 vs 5.52 ± 0.67; p < 0.001]. Conclusion: Our study recommends the use of joint aspiration as a therapeutic tool in the holistic management of acute knee haemarthrosis in addition to usual treatment of ice application, immobilization and oral tranexamic acid. Early factor replacement along with therapeutic joint aspiration is a key for better pain relief and a better functional outcome.

Diagnosis of Intraosseous Hibernoma of an Appendicular Skeleton in an Adult - A Rare Case Report.

Introduction: Hibernoma is an uncommon benign tumor composed of multivacuolated brown adipocytes described in the literature a decade back. Intraosseous hibernomas are extremely rare with propensity to affect axial skeleton. Involvement of appendicular skeleton has been reported only twice in the literature till date. Case Report: We present a case of solitary, painless mass in the left proximal tibia mimicking neoplasm in a 35-year-old male. The plain radiographs revealed a lytic lesion with well-defined margin at the junction of metaphyseal-diaphyseal region of the left proximal tibia. The lesion was hyperintense on T2 and hypointense on T1 with heterogenous enhancement on contrast imaging. FDG-PET showed high uptake of fluorodeoxyglucose. Histopathological examination revealed the presence of multivacuolated cytoplasm with abundant mitochondria suggestive of hibernoma. On immunohistochemistry, the cells were positive for S-100. Conclusion: The findings of imaging modalities are non-specific and histopathological examination is required to confirm the diagnosis of hibernoma. Intraosseous hibernoma needs to be considered as a differential diagnosis of sclerotic bone lesion. Further, evaluation with regular follow-up with imaging will be required if the mass undergoes any clinical changes. Both radiologists and pathologists, need to be aware of this rare entity to avoid misdiagnosis of the uncommon lesion.

Linalool reduces the virulence of Pseudomonas syringae pv. tomato DC 3000 by modulating the PsyI/PsyR quorum-sensing system.

Quorum sensing modulatory effect of linalool was tested for the first time against Pseudomonas syringae pv. tomato DC 3000, a bacterial plant pathogen responsible for causing huge losses worldwide. DC 3000 extensively regulates its virulence traits through quorum sensing mechanism involving expression of psyI, an acyl-homoserine lactone (AHL) synthase gene and psyR, a luxR-type regulator. In this study, exposure of DC 3000 to 80 ppm linalool concentration resulted in reduced biofilm formation, hampered motility, decreased AHL production, and reduced secretion of plant cell wall-degrading enzymes followed by negligible effect on the bacterial count and its metabolic activity. Extracellular polymeric substances (EPS), which play a crucial role in the development of biofilm and subsequent infection was significantly reduced which was further confirmed by Fourier Transform Infrared Spectroscopy. The qRT PCR analysis of the gene expression analysis of virulence genes (syringafactin production gene syfA, type III secretion system gene hrpA, flagellar genes fleQ and fliC, and coronatine production gene cfl unveiled significant downregulation of the same under Lin 80 ppm concentration. To further confirm the aforementioned possibilities, docking simulations run between PsyR and linalool suggested a strong interaction with the developed protein model. Overall, the treatment of DC 3000 with Lin 80 ppm affected the phenotypic and genotypic expressions associated with quorum sensing, thereby significantly reducing the infection rate as observed in in-vivo plant assay.

Rare Case of Gaucher's Disease Presenting as a Solitary Swelling of the Proximal Tibia Mimicking a Musculoskeletal Tumor in an Adult: A Case Report.

Introduction: Gaucher's disease is a congenital lysosomal storage disorder caused by an autosomal recessive mutation in B-glucocerebrosidase. It is a multi-system disease, wherein patients present with hematological abnormalities, joint pain, osteonecrosis, and developmental delay. We present a case of 38-year-old male with a painless solitary soft-tissue swelling over the left proximal tibia, eventually diagnosed it to be a case of Gaucher's disease. This case is unique in the literature, because this subcutaneous Gaucher mass was not associated with a significant past history and was being evaluated as a standard approach to a bone tumor. Case Presentation: A 38-year-old man presented to our outpatient department with a solitary, painless soft-tissue swelling of the left proximal tibia noticed 6 months back, which has gradually progressed to a present size of 9x5 cm over a period of 6 months. General physical examination revealed moderate splenomegaly. Radiographs showed an osteolytic lesion in the left proximal tibia without cortical erosion. Radiographs for skeletal survey revealed similar osteolytic lesions elsewhere. Hematological investigations revealed thrombocytopenia. A serum protein electrophoresis was found to be normal and the urine was negative for myeloma proteins. Blood workup for endocrine abnormalities was within normal limits. MRI of the lesion suggests bone infarct. Biopsy from the lesion showed a giant binucleate storage cell filled with glucocerebrosides suggestive of Gaucher's disease. The diagnosis was confirmed by elevated plasma levels of glucocerebrosidases. Conclusion: Gaucher's disease is a rare metabolic disease of the bone which may mimic a primary bone tumor or metastasis. A step-wise meticulous approach with biopsy and elevated plasma levels of glucocerebrosidase helps establish the diagnosis. Once must have a high index of suspicion for Gaucher's disease in an adult with multiple osteolytic lesions without any significant past medical and surgical history.

The influence of joint line restoration on functional outcome after primary total knee arthroplasty: A prospective study.

Objective: Restoration of proper joint line position after primary total knee arthroplasty (TKA) is important for improved knee function and kinematics. We reviewed the magnitude of joint line alteration and the resulting effect on post-operative knee outcomes scores at one year follow-up. Materials and methods: 120 patients who underwent TKA for primary osteoarthritis knee were included. Assessment of joint line position before and after surgery was performed with the help of bony landmarks (excluding osteophytes): Medial Epicondyle Joint Line distance (MEJL), Lateral Epicondyle Joint Line distance (LEJL) and Fibula Head Joint Line distance (FHJL) were calculated. Post-operative knee function was assessed using 'The Western Ontario and McMaster Universities Arthritis Index' (WOMAC) and 'Knee Society Score' (KSS) at one year follow-up. Results: Joint line elevation was observed in 104/120 (86.7%) patients and 16/120 (13.3%) patients had no joint line elevation. The mean joint line elevation was 3.00 (±2.13) mm. The patients were sub-classified into two study groups: Group A- Joint line elevation <5 mm and Group B- Joint line elevation ≥ 5 mm. The mean post-op one-year KSS score was significantly higher in patients in Group A compared to Group B (52.82 ± 7.564 vs. 40.73 ± 7.146; p < 0.001). The mean post-op one-year WOMAC score was lower in patients in Group A compared to Group B (65.51 ± 14.762 vs.75.64 ± 8.203) and the difference was statistically significant (p = 0.002). Conclusion: Elevation of joint line ≥5 mm from the pre-operative value has a negative impact on post-operative functional outcome in primary TKA.

Proximal Thoracic Kyphoscoliosis with Dorsal Myelopathy in a Case of Congenital Absence of Thoracic Pedicles: A Case Report.

CASE: A 14-year-old boy with proximal thoracic kyphoscoliosis associated with the bilateral absence of thoracic pedicles presented with progressive deformity, paraparesis, and difficulty in ambulation. The case was managed by preoperative halo traction, single-stage 2-level vertebral column resection, decompression, and arthrodesis of thoracic vertebrae. Two years postoperatively, the patient showed neurological improvement, leading to unassisted ambulation and fusion at the corpectomy site. CONCLUSION: Preoperative halo-gravity traction restores the sagittal and coronal balance, improves the functional status of the patient, and corrects the deformity to some extent. 3D printed models help in better understanding of osseous anatomy and minimizing intraoperative time.

Clinicoradiological outcome of percutaneous intralesional polidocanol in Aneurysmal Bone Cysts: A prospective study of 43 patients in a single tertiary care centre.

Objective: The study reports the efficacy of sequential instillations of intralesional percutaneous polidocanol in the treatment of skeletal ABC. The study also analyses the pain relief, recurrence, radiological outcome and complications after percutaneous sclerotherapy. Materials and methods: A total of 43 patients with ABC were managed by fluoroscopy assisted percutaneous intralesional sclerotherapy with 3% Injection Polidocanol under suitable anaesthesia. The pain relief was assessed by Visual Analog Scale (VAS) and the progressive healing of the lesion by Rastogi Classification. Patients were evaluated clinico-radiologically, pre-operatively and at monthly interval for the first three months and then at 6 months, one year and two years follow up. Result: The VAS score decreased significantly at six months follow up and was zero (No pain) at one year follow up. Out of 43 patients, 37 patients had Degree I (excellent) residual lesion and 6 patients had degree II (good) lesion at one year follow-up as per Rastogi classification. The lesions resolved completely by two-year follow-up with all 43 patients having Degree (excellent) I resolution. Conclusion: Our study highlights the efficacy of percutaneous intralesional polidocanol in the treatment of ABC's. The procedure is safe, simple and effective with excellent outcome. Sclerotherapy is highly beneficial for deep lesions which are difficult to assess and for comorbid patients who are medically unfit for surgery. Our study strongly advocates the use of sclerotherapy as the first line treatment for ABC, considering its clinical and radiological efficacy.

Identification and characterization of chickpea genotypes for early flowering and higher seed germination through molecular markers.

BACKGROUND: Chickpea is the fourth most important legume crop contributing 15.42% to the total legume production and a rich source of proteins, minerals, and vitamins. Determination of genetic diversity of wild and elite cultivars coupled with early flowering and higher seed germination lines are quintessential for variety improvement. METHODS AND RESULTS: In the present study, we have analyzed the genetic diversity, population structure, cross-species transferability, and allelic richness in 50 chickpea collections using 23 Inter simple sequence repeats (ISSR) markers. The observed parameters such as allele number varied from 3 to 16, range of allele size varied from 150 to 1600 bp and polymorphic information content (PIC) range lies in between 0.15 and 0.49. Dendrogram was constructed with ISSR marker genotypic data and classified 50 chickpea germplasms into groups I and II, where the accession P 74 - 1 is in group I and the rest are in group II. Dendrogram, Principal component analysis (PCA), dissimilarity matrix, and Bayesian model-based genetic clustering of 50 chickpea germplasms revealed that P 74 - 1 and P 1883 are very diverse chickpea accessions. CONCLUSION: Based on genetic diversity analysis, 15 chickpea germplasm having been screened for early flowering and higher seed germination and found that the P 1857-1 and P 3971 have early flowering and higher seed germination percentage in comparison to P 1883 and other germplasm. These agronomic traits are essential for crop improvement and imply the potential of ISSR markers in crop improvement.

Isolated L5 nerve root injury without osseous disruption in a case of gunshot injury to the paediatric spine-A case report.

INTRODUCTION: There exists sparse literature on Gunshot injuries (GSI) to the pediatric spine, its natural course, management protocols and outcomes following surgical intervention. Here, we present a projectile injury to the paediatric lumbar spine without any osseous disruption in a 5-year-old child requiring surgical management. CASE PRESENTATION: A 5-year-old child presented with a gunshot injury to the pediatric lumbar spine. On radiological imaging, there was no osseous disruption and an intraspinal canal projectile was embedded in an organised infected complex, compressing onto the left-sided L5 traversing nerve root with resultant grade 4 motor power of the left Extensor Hallucis Longus (EHL). Under fluoroscopic guidance using two separate mini-open incisions, the pellets were extracted. One from the spinal canal through left-sided L4 laminotomy and the other from the right paraspinal region. Post-surgical decompression and pellet retrieval there was gradual recovery to grade 5 motor power of Left EHL and improvement in the general condition of the child. CONCLUSION: The absence of osseous disruption can be attributed to the size of the projectile, widely spaced interlaminar spaces in the lumbar spine due to the absence of lumbar lordosis in the pediatric group and flexibility of the pediatric spine owing to its ligamentous laxity.

Evaluation of functional outcome and neurological recovery pattern in patients with retro-thecal tubercular epidural abscess managed at a tertiary center.

We performed a retrospective observational study to analyze the neurological recovery pattern in patients with a sub-laminar retro-thecal epidural abscess managed at our tertiary apex center from 2014 to 2020. We evaluated the Maximal Spinal Cord Compression (MSCC) ratio on Magnetic Resonance Imaging (MRI), the time interval between the appearance of neurological deficit and the initiation of management, spasticity as per Modified Ashworth Scale, presence of drug resistance, and the Lower Extremity Motor Score (LEMS). All patients were given anti-tubercular chemotherapy. We surgically managed 8 patients of which 6 required decompression alone, while 2 patients required additional instrumentation. 2 patients were managed conservatively of which 1 responded favorably to conservative treatment while the other patient showed a worsening of neurology following the detection of drug resistance and abrupt discontinuation of chemotherapy. The mean LEMS on admission was 20.2, which improved to 38.5 at the end of 1 year (p-value <0.05). The patients in whom the time interval between the onset of neurological deficit and the initiation of management was fewer than 6 weeks showed better LEMS and milder or absent spasticity at follow-up (p-value <0.05). The MSCC ratio did not have a significant correlation with the LEMS (p-value >0.05).

Integrated approach for spatial flood susceptibility assessment in Bhagirathi sub-basin, India using entropy information theory and geospatial technology.

Globally, floods as dynamic hydraulic hazard have caused widespread damages to both socioeconomic conditions and environment at various scales. Managing flood and management of water resource is a global challenge under the changing climatic condition. This study assessed flood susceptibility in the Bhagirathi sub-basin, India using entropy information theory and geospatial technology. Twelve flood susceptibility parameters such as land use/land cover, normalized difference vegetation index (NDVI), slope, elevation, geology, geomorphology, normalized difference water index (NDWI), soil, drainage density, average rainfall, maximum temperature, and humidity during monsoon season were utilized to examine flood susceptibility. Receiver operating characteristics (ROC) curve and Leave-One-Out Cross-Validation (LOOCV) techniques were carried out to validate flood susceptibility map. Kappa statistics was also used to check the reliability of the flood susceptibility model. Findings of the study revealed that nearly 45% area of the sub-basin was highly susceptible to flood followed by moderate (29.3%), very high (19%), low (6.9%), and very low (0.2%). These findings also revealed that nearly 92% area in the eastern, north-eastern, and deltaic sub-basin was susceptible to floods. ROC analysis indicated high success (0.932) and prediction (0.903) rates for the susceptibility map while LOOCV (R2 being 0.97) and Kappa (k = 0.934) have shown substantial prediction of the model. Hence, the susceptibility maps are useful for the local planners and government organization in designing the early flood warning system, and reducing the human and economic losses. The methodology used in this study is applicable for analyzing flood susceptibility at spatial scales in similar systems.
