Introduction: Congenital talipes equino-varus (CTEV) is amongst one of the most common paediatric foot deformities. Ponseti’s method is the standard way of treatment, however, some patients are left with residual or partially corrected deformities. Dynamic supination is one amongst them, where the foot supinates in swing phase of the gait cycle. It is due to a strong tibialis anterior and its weak antagonist. Materials and methods: We undertook a prospective interventional study in thirty patients of CTEV with residual dynamic supination deformity and treated them with tibialis anterior tendon transfer (TATT) using a button anchor. Minimum follow-up was six months after the surgery. Functional, subjective and objective evaluation was done using foot posture index (FPI), disease specific instrument (DSI) for clubfoot, clinician satisfaction grading and videotaped functional gait analysis. Statistical analysis was done using paired ‘t’ test and calculating p values. Results: We achieved good to excellent results in 93.3% of our patients and fair in 6.66%. None of our patients had poor results. Mean FPI improved from -1.93 to +0.3, DSI values also showed a significant reduction from 18.17 +/- 1.09 to 13.37 +/- 1.54 after surgery. A total of 90% had satisfactory gait post-surgery at 6 months follow-up. Conclusion: Tibialis anterior tendon transfer using a button anchor is effective in treatment of residual dynamic supination deformity.

Objectives: Artificial intelligence (AI) is reshaping healthcare by improving diagnosis and treatment planning, increasing operational efficiency, and streamlining administrative workflows. This paper integrates findings from an extensive PubMed search (2015–2025) with bibliometric analysis using RStudio and VOSviewer to investigate the comparative applications of AI methods in healthcare, collaborative networks, and emerging trends. Methods: A total of 1,243 records were identified through the PubMed search, and after removal of 143 duplicates, 1,100 records were screened. Following full-text assessment and exclusion of ineligible studies, 986 articles were included in the final bibliometric analysis. Results: The main research areas included robotic-assisted surgery, predictive analytics, diagnostic imaging, and precision medicine, with particular emphasis on the prevalence of machine learning and deep learning in imaging and the increasing application of natural language processing to unstructured medical information. Conclusion The review emphasizes the need for greater budgetary allocation to scalable and pragmatic AI technologies and for interdisciplinary cooperation among researchers, industry, and healthcare providers. Despite this growth, challenges such as algorithmic bias, data integration, and ethical concerns persist. The paper also highlights the importance of equitable collaboration, accountable AI, and multinational partnerships in ensuring that AI can be used ethically and efficiently in healthcare over the long term to improve patient care and biomedical innovation. It does so by mapping international and regional trends, identifying the most influential authors, institutions, and funding sources, and evaluating methodological approaches.

Objectives: Patients receiving hemodialysis (HD) are at increased risk of acquiring hepatitis B virus (HBV) and hepatitis C virus (HCV) due to repeated blood exposure, vascular access procedures, and blood transfusions. The study aimed to determine the seroconversion rates of HBV and HCV among patients undergoing dialysis and to identify associated risk factors. Methods: A total of 220 adult patients receiving dialysis who were seronegative for hepatitis B surface antigen (HBsAg) and anti-HCV antibodies at baseline were enrolled. Serologic testing was repeated at 6 months. Results: Sixteen patients (7.3%) seroconverted to HBsAg positivity, and 23 (10.5%) seroconvertedto anti-HCV positivity. HBV seroconversion was significantly associated with multiple dialysis center visits. HCV seroconversion was significantly associated with dialyzer reuse, multiple dialysis center visits, and dialysis duration ≥2 years. Elevated liver enzyme levels were stronglycorrelated with seroconversion for both viruses. Conclusion HBV and HCV seroconversion remain concerns in HD units. Standardized infection control practices, minimization of patient transfers, and strict adherence to nationalguidelines are essential to reducing risk.

The coronavirus disease 2019 (COVID-19) pandemic had an unprecedented global impact,resulting in both positive and negative consequences. The virus not only affected millions oflives worldwide but also caused long-term harm to multiple organ systems in many survivors,thereby substantially impairing quality of life. This persistent condition is now referred to as long COVID (LC). The aim of this study is to raise awareness of LC-related organ system impacts and to highlight the key role of artificial intelligence (AI) in mitigating these effects. The present research conducts a narrative review focusing on LC-related impacts. In this context, unstructured searches were conducted to identify a total of 69 relevant studies indexed in Embase, PubMed, Web of Science, or Scopus, each of which was reviewed by at least 2 experts with sufficient domain knowledge in health sciences. Based on the authors’ perspectives and insights, the review narratively examines damage to human organ systems attributable to LC and explores the role of AI in addressing LC-related challenges. Significant ethical, practical, and societal concerns arising from the extensive use of AI, particularly major issues such asdata privacy and algorithmic bias, are also discussed. LC has caused lasting impacts on humanorgan systems, while AI is offering substantial potential for LC-related care.

Pancreatic cancer is one of the most lethal malignancies, primarily due to late-stage diagnosis and limited therapeutic options. Cancer stem cells (CSCs) contribute to tumor heterogeneity, therapy resistance, and recurrence through activation of developmental pathways such as Hedgehog, Wnt, Notch, JAK-STAT, and Hippo. Identifying CSCs is therefore essential for understanding pancreatic ductal adenocarcinoma (PDAC) pathogenesis and advancing targeted therapies. This study compares the expression of key CSC-associated markers (CD44, CD117, OCT3/4, and c-Myc) in PDAC, fetal, and adult pancreas to elucidate CSC dynamics. Immunohistochemistry for CSC markers (CD44, CD117, OCT3/4, and c-Myc) was performed on PDAC tissues and control pancreatic samples (fetal pancreas 28–36 weeks and adult pancreas) to evaluate marker expression. Proliferative potential was assessed using CK7 and Ki-67 expression patterns. CD44 showed strong membranous and cytoplasmic expression in PDAC, moderate in fetal pancreas (epithelial/ductal regions), and minimal expression in adult tissue. CD117 was mainly restricted to stromal cells in PDAC, also present in fetal tissue but low in adults.c-Myc and Ki-67 were moderately expressed in PDAC, significantly higher than the control samples. CK7 demonstrated strong cytoplasmic staining in PDAC, moderate expression in adults, and weak expression in fetal samples. CD44 and c-Myc re-expression in PDAC supports their role as CSC-associated markers and potential drivers of tumor progression. CD117’s stromal localization suggests tumor–stroma interactions. These findings highlight developmental reactivation of CSC markers in PDAC, with implications for early detection and targeted therapy.

We present a rare anatomical variation of the deep femoral vein (DFV) originating from the popliteal vein (PV) with an associated aneurysm. The DFV arose from the PV at the adductor hiatus, exhibited an aneurysm, and coursed upward through the fourth osseo-aponeurotic opening of the adductor magnus muscle to enter the anterior thigh compartment before draining into the femoral vein. This unique variation likely resulted from developmental deviations during intrauterine life. The anomalous origin and aneurysm of the DFV may potentially cause venous hemodynamic disturbances, chronic venous insufficiency, increased risk of deep vein thrombosis, and potentially life-threatening pulmonary embolism. Anatomical variations of the DFV in terms of origin, course, or termination are rare but clinically relevant, especially in the context of vascular surgeries, imaging, and interventional procedures involving the femoral region.This case highlights the importance of recognizing venous anatomical variations and their clinical implications.

To investigate brain melanin deposition on magnetic resonance imaging (MRI) in hypomelanosis of Ito (HI) by presenting two clinical cases and reviewing relevant literature. Two patients clinically diagnosed with HI underwent comprehensive neurological and systemic evaluations. Detailed MRI was performed to identify parenchymal changes suggestive of melanin deposition. A literature review was conducted to compare the imaging findings and discuss embryological and neurocutaneous correlations. Both cases presented with typical hypopigmented cutaneous lesions but without dysmorphic features. MRI of the first child revealed left hemimegalencephaly, diffuse white matter abnormalities, and multiple nodular lesions that were T2-hypointense and T1-hyperintense, suggesting possible intracranial melanosis. In contrast, MRI of the second patient demonstrated T2 hyperintensities in the juxtacortical white matter of the medial occipital lobe with blooming on susceptibility-weighted imaging sequences; however, hemimegalencephaly was absent. Histological confirmation was not possible due to lack of consent for brain biopsy. We report a rare case of probable intracranial melanin deposition in HI, inferred from characteristic MRI signal patterns. These findings may reflect aberrant melanocyte migration into the brain, consistent with their shared neural crest origin with neurons. Although histopathological verification was not feasible, our observations underscore the need for further pathological validation and exploration of the neurocutaneous interface in pigmentary disorders.

Background: s/Aims: To evaluate the impact of unplanned conversion to open surgery on resection margin status and postoperative complications in patients undergoing minimally-invasive resection of colorectal liver metastases (CRLM). Methods: This study performed a proportion meta-analysis and meta-regression using random-effects modelling in accordance with PRISMA guidelines. Studies with at least 15 patients that reported conversion to open surgery in individuals receiving minimally-invasive CRLM resection were included. The association of unplanned conversion with postoperative outcomes was analyzed. Results: Eighty-six studies encompassing 18,138 patients were analyzed. The overall conversion rate was 5.8% (95% CI 5%–6.6%).Conversion was associated with improved R0 resection rates (coefficient: 2.167, p < 0.001) but was also linked to increased postoperative mortality (coefficient: 7.585, p = 0.001) and morbidity (coefficient: 1.737, p = 0.003); there was no significant impact on 5-year overall survival (coefficient: 0.700, p = 0.989) or 5-year disease-free survival (coefficient: –72.900, p = 0.157). Specifically, conversion due to oncological concern was associated with higher rates of R0 resection (coefficient: 0.638, p = 0.005); conversion resulting from iatrogenic injuries was associated with lower R0 resection rates (coefficient: –1.478, p < 0.001); conversion for technical difficulties was associated with lower postoperative morbidity (coefficient: –0.380, p = 0.006). Conclusions Unplanned conversion to open may carry prognostic and oncological implications for minimally-invasive resection of CRLM. Although conversion due to bleeding and iatrogenic injury is routinely considered, conversion prompted by technical difficulties or oncological concerns should not be considered failure, as it may be associated with improved patient outcomes.

Background: s/Aims: Hepatic artery pseudoaneurysm (HAP) is a condition associated with high mortality rates when untreated. Current literature lacks comprehensive understanding of complication rates and optimal treatment strategies. This study aims to analyze the etiology, technical success, and complication rates associated with endovascular and percutaneous management of HAP. Methods: A retrospective analysis was conducted, examining data on demographics, comorbidities, etiology, and embolic agents. A comparative analysis of hemoglobin levels, liver function tests, and renal function tests was performed before and 24–48 hours after the procedure. Results: The study included 49 patients (71% males) with a mean age of 46.44 (± 15.88) years. The common etiologies were post-operative complications (36.7%) and blunt abdominal trauma (26.5%). The right hepatic artery (RHA) was the most frequently involved site (57%). Endovascular embolization involved the use of coils, glue, and stent grafts, while percutaneous embolization was performed in six cases. The technical success rate for the endovascular approach was 97.6%, compared to 33% for the percutaneous approach. Hemoglobin levels stabilized post-procedure (mean post-procedure 8.9 g/dL vs. 7.9 g/dL at presentation), indicating effective hemostasis.Post-procedural complications included transient elevation of liver enzymes (22.4%), hepatic abscess (4.1%), and cholangitis (2.0%). Conclusions HAP is primarily caused by iatrogenic injury or blunt abdominal trauma, with a predilection for the RHA. Endovascular therapy proves to be a safe and effective treatment for this life-threatening condition. Although high technical success rates are achievable, the potential for ischemic complications necessitates a tailored treatment approach and the implementation of prophylactic measures when indicated.
