Abstract
An associated microbiome of any host helps it in different metabolic processes ranging from the decomposition of food to the maturation of gametes. Organisms with a parasitic mode of life, though present at nutritious sites inside their host, maintain their own microbiome. Nevertheless, the comprehensive characterization and functionality of microbiome in parasitic organisms remain understudied. We selected two nematode parasites of Kashmir Merino sheep viz;Haemonchus contortus and Trichuris ovis based on their higher prevalence, difference in mode of nutrition, habitation site and effect on host. The objective of the study was to explore the bacteria associated with these parasitic nematodes of sheep. We adopted a 16S rRNA metagenomic sequencing approach to estimate and compare the bacterial communities present in these two nematode species. Nematode parasites from Kashmir Merino sheep were identified morphologically and confirmed with DNA characterization. H. contortus was dominated by phylum Proteobacteria (57%), Firmicutes (25%), Bacteroidota (15%) and Actinobacteriota (3%). Conversely, T. ovis showed Proteobacteria (78%) followed by Firmicutes (8%), Bacteroidota (8%), Actinobacteriota (1%), Fusobacteriota (1%) and other phyla (4%). This study provides a comprehensive account of the microbiome composition of H. contortus and T. ovis, both of which are highly prevalent among Kashmir Merino sheep. Additionally, T. ovis exhibited a greater bacterial diversity compared to H. contortus. Notably, these nematodes were found to harbor certain pathogenic bacteria. This study can further be carried forward in gaining insights into the complex relationship between the microbiota of a parasite and its pathogenicity, reproductive potential and host microbiome modification.

Abstract
Introduction Open tendoachilles injuries are rare and associated with significant soft tissues complications. The objective of the present study was to assess the clinical outcome and safety of a simple and minimally invasive technique, with a goal to assess if it may help minimise flap and wound related complications in open tendoachilles injuries. Materials and methods This prospective study of four years duration included 20 patients with open tendoachilles injuries managed with a simple minimally invasive tunnel technique. The primary outcome variable was occurrence of a major soft tissue complication. The secondary outcome variables included functional outcome measured using AOFAS Ankle hind foot score, re-rupture of tendoachilles and need for revision surgery. Results None of the patients in the present series developed a serious soft tissue complication. Based upon the AOFAS hind foot scoring system, good to excellent outcome was achieved in 19 (95%) patients. All the patients were able to perform tip toe walking at six months post-surgery. None of the patients had a re-rupture of the tendoachilles and no patient needed a revision surgery. The complications encountered include thickening of the tendon at the repair site (15%), superficial wound infection (5%), stitch granuloma (5%) and hypertrophic scar (5%). Conclusion This technique seems to be promising in reducing the soft tissue complications associated with the surgical management of open tendoachilles injuries. Most patients had a good final clinical outcome. The technique is safe, simple and reproducible. However, further randomised control studies with a larger sample size assessing the technique are recommended.

Abstract
AbstractGlobally and in India, lung cancer is one of the leading malignancies in terms of incidence and mortality. Smoking and environmental pollution are the common risk factors for developing lung cancer. Traditionally, lung cancer is divided into small cell and nonsmall cell types, with nonsmall cell carcinomas including squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.In this review article, we describe the imaging recommendations and findings in the diagnosis, staging, and management of lung cancer, including the imaging of treatment-related complications.

Abstract
Congenital anomalies of the superior and inferior vena cava result from abnormal embryogenesis of cardinal veins. Duplication of superior vena cava (SVC) occurs in 0.3% of the general population of which only 8% drain into the left atrium. The prevalence of double inferior vena cava (IVC) is around 0.2-3%. The reported incidence of unilateral renal agenesis ranges from 1:1100 to 1:5000, and the association of double IVC with renal agenesis has been reported in only 11 cases in the literature. The conglomeration of such rare anomalies incidentally noted in a single patient is reported in this study. A 32-year-old man was referred to our department for Computed Tomography (CT) scan of the thorax. The patient was found to have dorsal kyphoscoliosis with hemivertebrae. The SVC was duplicated with the right SVC draining into the right atrium and the left SVC draining into the left atrium. The left kidney was not visualized in the abdomen. There was dual IVC with no intercommunicating interiliac vein. The right IVC maintained its normal course, while the left IVC continued as hemiazygos vein and joined left SVC in the thorax. Also noted was the aberrant origin of the right subclavian artery. This is the first reported case of combined superior and inferior vena caval anomalies along with left renal agenesis in a single patient in the literature. A review on the embryological basis is also described in this article.

Abstract
Background Dual-energy computed tomography (DECT) utilises the technique of simultaneous image acquisition of a body part at two different energy levels of the X-ray tubes. We used the DECT in this project to study its accuracy in non-invasive in vivo differentiation of uric acid (UA) calculi from non-UA calculi using the 3rd generation dual-source computed tomography (CT) scanner. Materials and Methods The DECT ratios of the various stones were noted and compared with the postextraction analysis of stones for composition. Sixty stones from 53 patients were included in the study, and their DECT results were compared with the post-extraction analysis (by infrared spectroscopy as the standard comparative method). Results DECT was highly sensitive and specific in the diagnosis of various types of calculi based on their dual-energy ratio. It was found to be 100% sensitive and specific for differentiating UA stones from the non-UA stones. The DE ratio for the UA stones was found to be 0.98-1.13. Most of the stones belonged to non-UA category (85%), and only 15% were UA calculi. The sensitivity and specificity in differentiating a calcium oxalate from non-calcium oxalate calculus was 97.8% and 92.3%, respectively. Conclusion DECT using the 3rd generation CT scanners is highly sensitive in the determination of urinary calculi composition which will be very helpful to the treating surgeon in selecting the optimal modality of treatment as UA stones are amenable to medical therapy while most of the non-UA stones require surgical intervention.
