Hepatoid tumors are rare neoplasms that arise outside the liver but exhibit morphological and immunophenotypic features resembling hepatocellular carcinoma. Although hepatoid differentiation sometimes occurs in pancreatic ductal adenocarcinoma, its occurrence in solid pseudopapillary neoplasm (SPN) is exceedingly rare. Consequently, the clinicopathological characteristics and natural history of this variant remain poorly understood. We report a case of a 37-year-old asymptomatic male with a 6mm solid pancreatic body lesion that was incidentally detected during routine abdominal ultrasonography. Multimodal imaging showed a well-circumscribed solid mass showing early-phase hyperenhancement relative to the surrounding pancreatic parenchyma. Tissue samples obtained via endoscopic ultrasonography contained polygonal epithelioid cells with abundant eosinophilic cytoplasm and a hepatoid appearance. In immunohistochemistry, HepPar-1 and CD10 were diffusely positive, chromogranin A and synaptophysin were absent, and β-catenin accumulated within the nucleus, all supporting a diagnosis of SPN with hepatoid differentiation. Although surgical resection was recommended, the patient declined and was subsequently managed with active surveillance. After 5 years of follow-up, the lesion remained morphologically stable without clinical progression. To our knowledge, this case report is the first to describe the long-term natural course of a pancreatic hepatoid SPN managed nonoperatively. The patient's maintained stability supports the indolent biological behavior of this rare variant. Thus, conservative management with close surveillance may be feasible for carefully selected patients with small, asymptomatic tumors. However, additional cases are needed to clarify optimal management strategies.

The kidney is the most frequently injured organ in pediatric blunt abdominal trauma. The success of conservative treatment is well-demonstrated for American Association for the Surgery of Trauma (AAST) grade I-III renal injuries. However, the optimal management of grade IV trauma remains controversial. This study aims to enhance the understanding of the optimal therapeutic approach for children with such lesions. Medical records of all children presenting with blunt abdominal trauma at our center between January 2013 and January 2020 were reviewed. Renal injuries were classified according to the 2018 AAST grading system, and mechanisms of injury were recorded. Detailed analysis was conducted on the patients with grade IV renal trauma, including mechanism of trauma, associated injuries, imaging, management, length of hospital stay, and follow-up. All 16 children with grade IV renal trauma were initially managed conservatively. Six (38 %) required no further intervention. Minimally invasive measures-ureteral stenting or angioembolization-were necessary for seven (43 %) patients. Urgent surgical exploration was needed in three (19 %) patients due to hemodynamic instability or vascular trauma. Nephrectomy was avoided in all three and no patient developed hypertension during follow-up. Renal function loss was observed in the only patient with renal arterial dissection. Approximately 40 % of our patients with grade IV blunt renal trauma were successfully managed conservatively. When including both conservatively and minimally invasively treated patients, the success rate rose to 80 %. Many injuries resulted from high-velocity winter sports accidents. This may have contributed to the severity of trauma at presentation. Conservative management was initially attempted in all patients with grade IV blunt renal trauma and succeeded in 40 % of cases. The success rate rose to 80 % when minimally invasive treatments were included. High-velocity winter sports injuries were associated with more severe trauma, but conservative management remained feasible in hemodynamically stable patients. This highlights the importance of mechanism of injury in guiding treatment and the potential need to adapt pediatric grade IV renal trauma classifications to optimize timing of intervention.

Clear Cell Chondrosarcoma (CCC) accounts for about 2% of all chondrosarcoma subtypes and typically presents in individuals during their third to fourth decades of life. This type of tumour most commonly arises in the proximal epiphyseal region of the femur, followed by the humerus, tibia, and small bones. It is frequently observed in males and often manifests as a painful lesion that reduces mobility, leading to misdiagnosis as a benign condition. Histopathologically, the tumour is characterised by round to polygonal cells having clear to vacuolated cytoplasm, arranged in diffuse sheets and lobules, accompanied by reactive woven bone formation and rare mitotic activity. Due to high recurrence rates associated with conservative treatments such as curettage, wide excision of the affected bone followed by reconstruction is recommended. We report a rare case of CCC involving the proximal end of the femur in a 30-year-old male patient who presented with right hip pain for five months. Radiological investigations revealed a well-defined osteolytic lesion confirmed by MRI. Biopsy showed clear cells, reactive woven bone and a few multinucleated giant cells. Herein, we discuss the several differentials possible and discuss the challenges encountered during final diagnosis.

Species-specific genomic information has the potential to transform modern conservation management strategies through improved genomic assessment and management outcomes. Gaining genomic insights into genetic diversity, adaptability and potential resilience against infectious diseases is essential to enhance conservation efforts for threatened species. Here, we describe the development of the first custom SNP array for an amphibian, designed for the critically endangered Pseudophryne corroboree, which has experienced a near-total population collapse due to the amphibian chytrid fungus (Batrachochytrium dendrobatidis, Bd). The array comprises 48,386 SNPs, with an average density of 5.45 SNPs per Mb and was effective in genotyping multiple tissue types, including non-lethal buccal swabs. Of the SNPs, 82.1% were polymorphic across 910 captive-bred P. corroboree individuals derived from ~54 families. Population genetic analysis revealed evidence of ancestral inbreeding and two historic bottlenecks, one coinciding with the arrival of Bd in Australia. Notably, we demonstrate successful cross-species amplification of 21,077 (43.6%) polymorphic loci in three closely related anurans, highlighting the array's broader utility beyond P. corroboree. This tool represents a valuable resource for investigating the genetic basis of disease resistance and developing management strategies for improving reintroduction outcomes in P. corroboree, while also providing a foundation for advancing conservation genomics in other amphibian species.

Ectopic spleen, or Wandering Spleen (WS), is a rare condition caused by laxity of splenic suspensory ligaments. While often asymptomatic, it may present with life-threatening complications such as torsion and infarction. We present a case of a 41- year-old female with a history of breast cancer who developed left-sided abdominal pain. Imaging confirmed an ectopic spleen in the pelvis resting on the urinary bladder, receiving its blood supply from the coeliac trunk. Computed Tomography (CT) also showed a well-demarcated area of non-enhancement at its inferior pole, along with twisting of the vascular pedicle associated with surrounding free fluid representing splenic volvulus and infarction. Enoxaparin 72 mg SQ BID was initiated for concurrent splenic vein thrombosis, and the patient was discharged on Rivaroxaban 20 mg PO OD. Over 16 months, serial imaging showed resolution of infarction and maintained splenic vascularity without surgical intervention. This case demonstrates that conservative management of WS with infarction may be viable with close monitoring and anticoagulation.

The use of spinal cord stimulation (SCS) for managing severe refractory chronic pain has expanded considerably due to positive statistical evidence regarding its use; however, the statistical robustness of the underlying randomized controlled trials (RCTs) requires further scrutiny. One such tool that can be used for this purpose is the fragility index, which quantifies how many individual outcome events must be altered for an outcome to lose statistical significance. Thus the index can be used quantitatively to assess the stability and robustness of an RCT's conclusions, with higher values indicating increased trial stability. This study assesses the fragility of pain outcomes across RCTs investigating SCS for chronic pain to better understand the quality and robustness of evidence. A systematic search was conducted for RCTs assessing SCS for any chronic pain indication. The primary outcome was an evaluation of the trial-specific fragility index for the prespecified pain primary outcomes of RCTs. Secondary outcomes included an evaluation of fragility for (1) specified indications for SCS therapy, (2) reported pain outcomes appearing in three or more RCTs, (3) the presence/absence of a conflict of interest, and (4) comparisons of SCS to conservative management or different SCS waveform modalities. A total of 30 RCTs were included. The median (interquartile range [IQR]) fragility index across the primary outcome of all trials was 5.45 (3.00 to 11.45). There was no statistical difference between the (1) types of outcomes (dichotomous vs. continuous; P = 0.710), (2) primary versus secondary pain outcomes ( P = 0.771), or (3) presence versus absence of trial conflict of interest ( P = 0.753). Indications with a median (IQR) fragility score greater than three included persistent spinal pain syndrome type 2 with a score of 8.00 (2.80 to 12.60), painful diabetic neuropathy with a score of 6.00 (3.00 to 11.80), complex regional pain syndrome with a score of 7.20 (4.62 to 81.50), mixed etiologies with a score of 9.00 (3.00 to 38.00), and other etiologies with a score of 3.00 (1.00 to 8.55). This study suggests that the majority of RCTs investigating primary pain outcomes after SCS therapy are robust with relatively high fragility scores. Reporting the fragility of outcomes in trials can provide a more comprehensive assessment of trial robustness and can further aid clinicians in interpreting trial results and making informed treatment decisions.

To evaluate the effectiveness of spatial superimposition of cone-beam computed tomography (CBCT) scans acquired at baseline and 6-month follow-up for monitoring bone healing in mandibular cystic lesions, aiming to reduce variability in conventional volumetric comparisons and enhance accuracy, reproducibility, and spatial fidelity of radiographic assessments. Two CBCT scans of a single patient (baseline, T0; follow-up, T1) were imported into 3D Slicer v5.8.0. The mandible was isolated by manually cropping a region of interest, and the cystic lesion was segmented semi-automatically using the Grow from Seeds tool. A rigid six-degree-of-freedom registration aligned T1 to T0; the resulting transformation matrix was applied to the T1 segmentation to enable direct voxel-wise comparison. Lesion volumes were measured, and spatial subtraction analysis quantified the resorbed area. Lesion volume decreased from 1841.64 mm3 at T0 to 1362.62 mm3 at T1, corresponding to an absolute reduction of 479.02 mm3 (26.0%). The subtraction mask accurately localized regressed voxels, confirming both the magnitude and spatial distribution of bone healing. Potential limitations related to CBCT artifacts and the need for operator-dependent manual steps should be considered when interpreting the results. Overall, CBCT superimposition with semi-automatic segmentation provides an objective, consistent, and anatomically precise approach for monitoring mandibular cyst regression and may represent a useful tool to support conservative management strategies.

Introduction: Oesophageal perforation is a life-threatening condition with high mortality rates. Various treatment options are available for the management. Oesophageal exclusion with diversion completely diverts the secretions entering the mediastinum, thereby prevents mediastinitis. Aim: The present study aimed to estimate mortality and the causes of oesophageal perforation in patients who underwent oesophageal exclusion and diversion procedure. Materials and Methods: The present retrospective observational study was conducted in Surgical Gastroenterology Department at Madras Medical College,Tamil Nadu, India from January 2019 to May 2024. A total of 46 patients had oesophageal perforation; 14 patients were managed conservative treatment, 32 patients were managed by operative treatment, including 25 patients who underwent oesophageal exclusion and diversion procedure. The surgical outcome of these 25 patients who underwent diversion cervical oesophagostomy and oesophageal exclusion for oesophageal perforation were evaluated. Parameters like age, sex, cause of perforation, location of oesophageal perforation, duration from symptom onset to hospital admission, postoperative morbidity, and mortality were recorded. Results: The mean age of the patients was 44.16 years, with 16 male and 9 female. Mortality rate was 4 (16%). The thoracic portion of the oesophagus was the most common site of perforation in 24 (96%) patients. Spontaneous perforation (9 patients, 36%) was the most common cause of oesophageal perforation, followed by foreign body-induced perforation (8 patients, 32%). Conclusion: Oesophageal diversion and exclusion procedure can be safely performed in a septic patients and in patients with delayed presentation. Oesophagostomy reversal is also an easy technique that does not cause much morbidity to the patients. In most of the patients, oesophagostomy that spontaneously closed doesn’t require reversal.

This review summarises recent findings from the past decade on infraoccluded primary molars, focusing on diagnosis, aetiology, prevalence, associated findings and clinical consequences, and to compare these with earlier literature to support improved clinical management. A systematic literature search was conducted according to PRISMA guidelines, evaluating MEDLINE (PubMed), Cochrane Library, Web of Science, and Embase from 2014 to 2025. Randomized controlled trials (RCT), non-randomized studies of interventions (NRSI), cohort studies, case-control studies and cross-sectional studies published in English and German were included. Case series, case reports, expert opinions and commentaries were excluded. Of 2816 publications identified, 30 met the inclusion criteria after screening and full-text review. These studies addressed prevalence (n = 17), retained molars (n = 4), retained molars without successors (n = 5), aetiology (n = 1), diagnosis (n = 1), mandibular growth impact (n = 1), and interventions (n = 1). Current evidence provides new insights into the aetiology and clinical management of infraoccluded primary molars. Genetic factors, particularly those related to epithelial development and inflammatory signalling pathways, are increasingly recognised. Conservative treatment approaches have gained traction, emphasizing alveolar preservation over orthodontic considerations of craniofacial growth. Most cases are mild and occur unilaterally in mandibular first primary molars. Early-onset infraocclusion is linked to a less favourable prognosis. Root resorption shows age-related variability. However, conflicting evidence exists regarding the association of infraocclusion with root resorption, especially in cases of tooth agenesis, and its correlation with mandibular growth rotation. Additionally, prevalence data remain inconsistent due to heterogenous classification, underscoring the need for further research.

Trigeminal neuralgia (TN) is a pain condition characterized by paroxysmal, electric shock-like facial pain, affecting one or more areas of the branches. Approximately 33%-50% of patients require invasive treatment. Radiofrequency thermocoagulation (RFTC) is an established method for managing drug-resistant and chronic TN. This study evaluates treatment response quality and complication rates in repeated RFTC procedures for TN patients. In this retrospective analysis, patient records were extracted from the electronic medical records of Kuopio University Hospital, using the trigeminal neuralgia diagnosis code and the procedure code for thermal destruction of a cranial nerve. Data collected included sex, age, treatment outcomes at 3-month follow-up, presence of complications, technical details, and procedural success for each intervention. Data from 140 patients were analyzed. An excellent or good response was observed in 79% of patients after the first procedure, 62.9% after the second, and 42.3% after the third. Complication rates were 15.7%, 19.6%, and 42.9%, respectively. Logistic regression analysis showed that complication risk was significantly associated with tertiary procedure and female sex. Development of painful post-traumatic trigeminal neuropathy (PTTN) was more common after repeated interventions; 1.4% after the first, 3.1% after the second, and 13.8% after the third procedure. RFTC is an effective and safe method for treatment for persistent trigeminal neuralgia when conservative treatment fails. However, its benefits diminish, and risks increase with each additional procedure, particularly the third. Based on these findings, reintervention should generally be limited to a single repeat procedure.
