Background and Clinical Significance: Non-small-cell lung cancer (NSCLC) with EGFR mutations, particularly de novo compound mutations such as exon 19 deletions (Ex19del) with T790M substitutions, present a significant clinical challenge due to resistance to many treatments. While treating these patients, the administration of osimertinib, a third-generation EGFR inhibitor, after immunotherapy can lead to unique immune-related adverse events (irAEs), such as pneumonitis and, rarely, hepatitis. Case Presentation: A 36-year-old Filipino woman presented with metastatic NSCLC harboring de novo Ex19del and T790M mutations. Despite initial therapy with carboplatin and paclitaxel, followed by chemoimmunotherapy, the patient’s disease progressed. She subsequently developed severe hepatitis from osimertinib after her prior immunotherapy with pembrolizumab. After the hepatitis resolved with high-dose steroids, osimertinib was switched to afatinib, but her disease rapidly progressed with new metastases. A second attempt at osimertinib rechallenge, with concomitant prednisone, resulted in substantial disease control, including improved leptomeningeal disease (LMD) and no recurrence of hepatitis. Conclusions: This case underscores the feasibility of rechallenging with osimertinib in patients who experience adverse events such as hepatotoxicity, provided that appropriate management strategies, such as steroid therapy, are employed. The successful rechallenge in this case highlights the potential of osimertinib as a viable option in advanced EGFR-mutant NSCLC, even after prior treatment-related complications. Full article

Background and Clinical Significance: Fulminant pulmonary embolism (PE) leading to an out-of-hospital cardiac arrest (OHCA) is associated with a high mortality rate and cardiopulmonary resuscitation (CPR) frequently failing to achieve return of spontaneous circulation (ROSC). Extracorporeal CPR (eCPR) has emerged as a potential life-saving intervention. Case Presentation: A 66-year-old woman suffered an OHCA due to massive PE, presenting with pulseless electrical activity (PEA). After 90 min of pre- and in-hospital CPR without sustained ROSC, venoarterial extracorporeal membrane oxygenation (va-ECMO) was initiated as eCPR upon arrival at the hospital. Even after implantation of the va-ECMO, there was initially a pronounced acidosis (pH 6.9) with a high elevated lactate level (>30 mmol/L); these factors, together with the prolonged low-flow period, indicated a poor prognosis. Further diagnostic tests revealed intracranial hemorrhage (subdural hematoma), and systemic lysis was not possible. With persistent right heart failure, surgical thrombectomy was performed during hospitalization. Intensive multidisciplinary management finally led to successful therapy and weaning from mechanical ventilation, as well as to complete neurological recovery (CPC-Score 1-2). Conclusions: This case illustrates that eCPR can facilitate survival with good favorable neurological outcomes despite initially poor prognostic predictors. It underscores the importance of refining patient selection criteria and optimizing management strategies for eCPR in refractory cardiac arrest secondary to PE. Full article

Background and Clinical Significance: Robotic surgery reduces the need for extensive surgical approaches and lowers perioperative complications. In particular, it offers enhanced dexterity, three-dimensional visualization, and improved precision in confined anatomical spaces. Pelvic masses pose significant challenges due to their close relationship with critical neurovascular structures, making traditional open or laparoscopic approaches more invasive and potentially riskier. Robot-assisted resection, combined with intraoperative neurophysiological monitoring, may therefore offer a safe and effective solution for the management of complex pelvic lesions. Case Presentation: An 18-year-old woman was incidentally diagnosed with an 11 cm asymptomatic pelvic mass located anterior to the sacrum. Initial differential diagnoses included neurofibroma, teratoma, and myelolipoma. Histopathological examination confirmed a ganglioneuroma. Following multidisciplinary discussion, the patient underwent a robot-assisted en bloc resection using the Da Vinci Xi multiport system. Preoperative planning was aided by 3D modeling and intraoperative navigation. Conclusions: Surgery lasted 322 min. Preoperative and postoperative eGFR values were 145.2 mL/min and 144.0 mL/min, respectively. The lesion measured 11 cm × 9 cm × 8 cm. The main intraoperative complication was a controlled breach of the iliac vein due to its close adherence to the mass. No major postoperative complications occurred (Clavien-Dindo Grade I). The drain was removed on postoperative day 3, and the bladder catheter on day 2. The patient was discharged on postoperative day 5 without further complications. Presacral ganglioneuromas are rare neoplasms in a surgically complex area. A multidisciplinary approach using robotic-assisted laparoscopy with nerve monitoring enables safe, minimally invasive resection. This strategy may help avoid open surgery and reduce the risk of neurological and vascular injury. Full article

Background and Clinical Significance: Perforation of the left ventricle related to microaxial ventricular assist devices (Impella) is a rare but fatal complication related to placement or adjustment. It results in left ventricular hemorrhage and tamponade, leading to rapid deterioration and death. Case Presentation: We present a case report of a 73-year-old man who developed this complication postoperatively and was successfully managed to a full recovery. Conclusions: To our knowledge, he is the only reported patient to have this complication outside the setting of immediate placement who subsequently survived to discharge. Full article

Background and Clinical Significance: The incidence of persistent ductus arteriosus (PDA) in preterm infants is the highest and depends on their birth weight (BW) and respiratory condition after birth. Previously, after the unsuccessful drug treatment, surgical ligation was the primary treatment option. However, according to clinical studies, the Amplatzer Piccolo Occluder was approved for PDA closure for patients ≥700 g. In our country, percutaneous PDA embolization has not been performed yet. Case Presentation: We present three premature infants with hemodynamically significant patent ductus arteriosus (hsPDA) in whom percutaneous occlusion was performed using the Amplatzer Piccolo Occluder (APO). The average gestational week (GW) was 27 ± 1, while body weight was 1030 ± 60 g. All patients had respiratory deterioration, with dilatation of the left heart chambers, and renal failure. The second developed a severe form of broncho-pulmonary dysplasia. Transthoracic echocardiography (TTE) examinations revealed a hemodynamically significant PDA (LA/Ao 1.8–2.2) and medical closure was unsuccessfully carried out. Due to the hemodynamically significant PDA maintenance in all neonates, transvenous PDA closure was performed using the APO (APO 9-PDAP-04-02-L, 9-PDAP-04-04-L, 9-PDAP-05-054L, respectively). The entire devices, with both retention discs, are implanted within the duct. TTE pointed out adequate device position without descending aorta, left pulmonary artery obstruction, residual shunt, and reverse remodelling of the left ventricle and left atrium. The first newborn was weaned from mechanical ventilation three days after the procedure and discharged three weeks after. The second patient was extubated 2 weeks after the procedure, and even the severe BPD, X-ray showed improvement. The third patient’s renal failure completely resolved, weaned from inotropic drug support and mechanical ventilation. Conclusions: Due to a significantly lower complication rate than surgical ligation, we will strive to make percutaneous PDA occlusion a new standard for treatment in newborns, especially preterm newborns, in our country.

Background and Clinical Significance: The mesenchymal–epithelial transition (MET) exon 14 skipping mutation (METex14) is a rare genetic alteration occurring in non-small cell lung cancer (NSCLC). Tyrosine kinase inhibitors (TKIs) are the approved treatment for first-line therapy in a metastatic setting. However, the unusual presentation of gastrointestinal metastasis and leptomeningeal carcinomatosis (LMD) poses significant treatment challenges. Case Presentation: Here we report a case of a 72-year-old male with metastatic METex14-positive NSCLC, presenting with brain and duodenal metastases. Conclusions: The patient responded exceptionally well to first-line chemoimmunotherapy, achieving clinically complete remission for 2 years. He subsequently developed cerebellar metastasis and leptomeningeal disease (LMD) but demonstrated a remarkable response to tepotinib and continued to enjoy radiographic complete remission over 2.5 years at the time of this report.

Background and Clinical Significance: Diabetic ketoacidosis (DKA) is a serious and potentially life-threatening condition, often triggered by infections or undiagnosed diabetes. Spontaneous pneumomediastinum (SPM) and pneumothorax are rare but recognized complications of DKA, possibly due to alveolar rupture from increased respiratory effort or vomiting. Sometimes, acute pancreatitis (AP) may further complicate DKA, but the co-occurrence of these three conditions remains exceptionally rare. Case Presentation: We describe the case of a 60-year-old woman without a known history of diabetes who arrived at the emergency department with abdominal pain, fatigue, vomiting, and altered mental status. Initial laboratory findings showed metabolic acidosis, hyperglycemia, and elevated anion gap, consistent with DKA. Imaging revealed spontaneous pneumomediastinum and subsequently a left-sided pneumothorax, without evidence of trauma or esophageal rupture. Epigastric pain, along with elevated serum lipase and CT findings, also confirmed acute pancreatitis. Despite the complexity of her condition, the patient responded well to supportive treatment, including oxygen therapy, fluid resuscitation, insulin infusion, and antibiotics. She was discharged in good condition after 28 days, with a confirmed diagnosis of type 2 diabetes, without further complications. Conclusions: This case highlights an unusual combination of DKA complicated by spontaneous pneumomediastinum, pneumothorax and acute pancreatitis in a previously undiagnosed diabetic patient. Because prompt intervention can lead to favorable outcomes even in complex, multisystem cases, early recognition of atypical DKA complications is critical in order to avoid misdiagnosis.

Background and Clinical Significance: Mitral valve prolapse (MVP) is commonly benign, but may result in life-threatening arrhythmias and sudden cardiac death (SCD). Mitral annular disjunction (MAD) often coexists with mitral valve prolapse (MVP) and has been implicated in the development of ventricular arrhythmias through myocardial stretch and fibrosis. Case Presentation: Here, we present a case that highlights the diagnostic value of multimodal imaging in evaluating ventricular ectopy in the context of MVP and MAD. A 72-year-old male presented to the cardiology clinic with palpitations and fatigue, compounded by an arrhythmia identified by his Apple Watch. Holter monitoring revealed premature ventricular contractions (PVCs), with cardiac magnetic resonance imaging (CMR) demonstrating MAD and basal inferolateral scarring. Despite minimal symptoms and normal echocardiographic imaging, CMR findings highlight the utility of advanced cardiovascular imaging in patients with newly detected ventricular arrhythmias. Conclusion: This case highlights the importance of integrating consumer wearables and advanced imaging in evaluating ventricular ectopy and its evolving role in risk stratification for patients with MVP, even in the absence of overt symptoms.

Background and clinical significance: Functional/dissociative seizures (FDSs) in adolescents are paroxysmal events which superficially resemble epileptic seizures or syncope. This study evaluated the effectiveness of brief cognitive analytic therapy (CAT). Case presentation: The patient was a 17-year-old white cisgender male with a diagnosis of non-epileptic attack disorder. The functional/dissociative seizures were treated with 8-session CAT, with follow-up at 5 weeks. Two target problems (TPs) and associated target problem procedures (TPPs) were rated for recognition and revision at each session and at follow-up. An A-B-C-FU single-case experimental evaluation of the TP/TPPs was conducted. Nomothetic outcome measures (DES-2 and RCADS) were administered at session 1, session 8, and at follow-up, and the YP-CORE and the Session Rating Scale were completed at each session. The patient was independently interviewed using the Change Interview 13 weeks after completing therapy. The results show that CAT effectively increased the recognition and revision of TPs/TPPs, four specific changes occurred (including cessation of functional seizures). There were pre–post reliable and clinically significant improvements to psychological wellbeing, but these were not maintained at follow-up. Conclusions: This study indicates that CAT was a partially effective intervention. The use of CAT as a treatment for FND in adolescents holds promise, but more research is needed. Full article

Background and Clinical Significance: To describe the effectiveness of alveolar ridge preservation under the radiological and histological analysis of a customized resorbable scaffold three-dimensionally printed with polycaprolactone (PCL) reinforced with a coating of a copolymer of polycaprolactone-block-polyethylene glycol (PCL–PEG) by electrospray. Case Presentation: A 62-year-old male with vertical root fractures of teeth #14 and #15. From the cone beam CT (CBCT) image, the scaffold root replicas were designed with the shape of the roots and printed with PCL coated with PCL–PEG by electrospray. The scaffold was inserted into the alveolar bone and maintained with a tension-free flap closure. After six months, a CBCT of the surgical site and histological analysis of a bone sample at the dental implant installation site were performed. After 6 months, the wound in tooth #14 was closed, clinically proving no adverse reaction or complications. The histological analysis of the bone sample showed new bone formation with lamellar structure, Haversian canal structure, and osteocyte spaces. However, the scaffold in tooth #15 was exposed and not osseointegrated, and it was covered with membranous tissue. Histologically, the sample showed tissue compatible with lax connective tissue with mixed inflammatory infiltrate. In tooth #14, the dental implant presented an insertion torque >35 Ncm and was rehabilitated three months after its installation. Conclusions: Three-dimensional printed PCL scaffolds showed the ability to regenerate vital and functional bone with osseointegration capability for maxillary bone regeneration and oral rehabilitation based on dental implants. A case of inadequate scaffold osseointegration accompanied by lax connective tissue formation is shown. Full article

Background and Clinical Significance: Implantation of an embryo in the cervical canal is the rarest location of ectopic pregnancy, as it occurs between 1 in 1000 and 1 in 18,000 pregnancies. Dilation and curettage in previous pregnancies have been identified as risk factors in most cases. Other predisposing factors include pelvic inflammatory disease (PID), prior tubal surgeries, assisted reproductive technologies, as well as the presence of fibroids and intrauterine. Importantly, ectopic pregnancies are the main cause of maternal morbidity and mortality in the first trimester. Given the rarity of cervical ectopic pregnancies (CEPs) and the lack of specific recommendations, clinical data supporting current evidence is of utmost significance. Case Presentation: A 29-year-old nulliparous woman presented with spotting from the genital tract and lower abdominal pain persisting for four days. Pregnancy could not be ruled out based on the patient’s medical history. The level of β-Human chorionic gonadotropin (β-HCG) on admission was 1487.99 mIU/mL. The first ultrasonography examination revealed a non-specific imaging appearance suggestive of the presence of cervical mucus. Targeted examination with visualization of the cervical canal revealed a gestational sac measuring 4–5 mm in diameter, containing an embryonic echo. The patient was treated with 84 mg of methotrexate (MTX) i.v. in a 1, 3, 5, 7 scheme along with 0.1 mg/kg calcium folinate i.m. in a 2, 4, 6, 8 scheme prior to curettage. Conclusions: A diagnosis of cervical pregnancy cannot be excluded even in the absence of prior risk factors. Methotrexate should be considered a safe and efficient option in the management of CEP. As shown in our case, early detection of CEP is of utmost significance. Full article

Background and Clinical Significance: Papillary Fibroelastoma is a benign primary cardiac tumor, commonly located in a valvular position, predominantly on the aortic valve. Case Presentation: We present a 73-year-old male patient with a medical history of chronic lymphatic leukemia, kidney failure, diabetes, and obstructive sleep apnea. In a routinely performed echocardiogram an abnormal structure in the left ventricle was found. The patient presented completely asymptomatically at the time of examination. A cardiac magnetic resonance-scan provided further information about the size and localization of the tumor in the left ventricle, which seemed to be attached to a papillary muscle and was about 1.6 cm in diameter. Due to visible scarring of the myocardia, which was identified in the scan, a cardiac catheter examination was performed. A coronary artery disease was detected with a severe stenosis in three vessels. During an elective bypass-operation, the removal of the structure was performed with an approach through the left atrium, passing the mitral valve using a valve sizer for better exposure. The tumor of 1 cm presented macroscopically with an anemone-like shape. The histopathological examination confirmed the intraoperative assumption of a papillary fibroelastoma, found in an aberrant location. Conclusions: Unexpectedly challenging surgical removals of structures in the left ventricle require innovative techniques with available instruments for better exposure. Full article

Background and Clinical Significance: Non-prosthetic peri-implant fractures (NPPIFs) are rare injuries occurring around internal fixation devices, and are distinct from periprosthetic fractures. While most studies focus on the femur, humeral NPPIFs remain poorly documented. This case illustrates a complex humeral NPPIF and highlights key surgical considerations. Case Presentation: A 62-year-old woman presented with a spiral humeral shaft fracture (AO 12B2) after a fall. Following closed reduction and antegrade intramedullary nailing, an intraoperative peri-implant fracture occurred at the distal interlocking screw. CT imaging revealed a complex fracture extending from the lateral condyle to the proximal humerus. Treatment included implant removal and open reduction with dual plate fixation—lateral distal and helically contoured proximal plates—plus cerclage bands and antibiotic-loaded beads. Recovery was uneventful, with a full range of motion achieved at six months. At one year, the DASH score and MEPS were 86 and 75, respectively. Conclusions: Humeral NPPIFs are challenging and require individualized, biomechanically sound strategies. This case reinforces the importance of intraoperative assessment and careful implant selection in humeral fracture management. Full article

Background and Clinical Significance: Local anesthetic injections, routine in dental practice, ensure pain control during procedures like root canal treatments. Though generally safe, they can occasionally cause hematomas, localized blood accumulations in tissue planes. Rapidly expanding hematomas in the head and neck are exceptionally rare but dangerous due to anatomical complexity, potentially threatening the airway. This case report emphasizes the critical need for the prompt recognition and management of such complications to prevent life-threatening outcomes, highlighting vigilance in routine dental procedures. Case Presentation: A 63-year-old male presented with rapidly enlarging right buccal swelling four hours post-local anesthetic injection for a root canal on a right maxillary molar. Examination showed warm, erythematous edema and buccal ecchymosis; a CT scan confirmed a 3.8 cm × 8.4 cm × 5.5 cm buccal space hematoma. His medical history revealed controlled type 2 diabetes and hyperlipidemia, and his coagulation was normal. Conservative management failed as the hematoma progressed, limiting mouth and eye opening. Urgent surgical decompression under general anesthesia evacuated clots and ligated facial and angular arteries. ICU monitoring ensured airway stability, with discharge on day three with antibiotics and follow-up. Conclusions: This case highlights the rare potential for dental anesthetic injections to cause rapidly progressive hematomas, requiring urgent surgical intervention and multidisciplinary care to prevent airway compromise. Early recognition, imaging, and decisive management are vital in achieving favorable outcomes in such serious complications. Full article

Background and Clinical Significance: Ventricular septal defect (VSD) is a rare but serious complication following myocardial infarction (MI) that can lead to cardiogenic shock and carries a high mortality rate. Acute mitral regurgitation (MR) is another severe complication of MI with additional risks of mortality. The optimal timing of surgical intervention for VSD with MR is still being debated, and delaying surgery in medically manageable patients has been associated with improved survival. However, managing these patients in the intensive care unit (ICU) presents unique challenges. Case Presentation: In this paper, we present the case of a 52-year-old male with comorbidities who developed post-MI VSD with severe MR and underwent successful delayed surgical repair and mitral valve replacement. Our aim is to highlight the clinical characteristics, diagnostic approach, and management strategies of this rare complication in the critical care setting. The patient presented in cardiogenic shock and acute pulmonary edema. After stabilization using an intra-aortic balloon pump, pre- and afterload reducing pharmacotherapy and non-invasive mechanical ventilation, a watchful waiting strategy was employed, and surgery was performed on day 21 after hospital admission. Surgery was performed under general anesthesia, and the patient did not develop any complications related to the intra-aortic balloon pump or novel organ dysfunction. Conclusions: This case highlights the importance of a multidisciplinary approach to managing post-MI VSD with MR and emphasizes the need for careful patient selection and timing of surgical intervention in the critical care setting. Clinicians should be aware of the potential benefits of delaying surgical intervention in medically manageable patients, while also considering the unique challenges of managing these patients in the ICU.

Background and Clinical Significance: This case presents a rare variation in mesenteric and pelvic vasculature that holds relevance for endovascular procedures. Limited published cases of the testicular artery arising off the inferior mesenteric artery exist in the literature and play an important role in clinical outcomes. Case Presentation: An 89-year-old male presented with gastrointestinal bleeding from diverticulosis. During an arteriogram to locate and assess sigmoid arteries for embolization, an unusual anatomical variant of the left testicular artery was discovered. Typically, the left testicular artery originates from the abdominal aorta below the renal arteries. However, in this patient, the left testicular artery was found to directly branch off the inferior mesenteric artery, while the superior rectal artery was absent from the inferior mesenteric artery. Conclusions: Awareness of such vascular variations is essential for interventionalists to optimize procedural success and minimize complications. Recognizing potential vascular anomalies, such as those presented in this case, is essential for effective pre-procedural planning and intraoperative management to improve patient outcomes.

Background and Clinical Significance: Kidney transplantation remains the most effective method of renal replacement therapy. Living donor transplantation offers several advantages—reduced cardiovascular risk, better graft survival, and preemptive intervention. However, donor obesity is a growing concern, as it is usually associated with perioperative and long-term complications, which can affect donor eligibility. Bariatric surgery is a standard recommendation for patients with a BMI over 35 kg/m². There are limited data on the use of pharmacological agents for weight reduction in kidney donors. This case presents a successful conservative treatment with GLP-1 receptor agonist in an obese woman wishing to donate a kidney to her son. Case Presentation: We are presenting the case of a 63-year-old woman with grade II obesity who was initially denied being a kidney donor to her son because of her weight. Under these circumstances, she underwent comprehensive lifestyle modification in the cardio-obesitology clinic (caloric restriction, physical activity, and pharmacological treatment with liraglutide). During the 3-month follow-up, she decreased her BMI to 33.4 kg/m², and subsequent examinations confirmed no surgical contraindications to donating a kidney. Despite hematuria, biopsy and genetic testing revealed a benign carrier condition of Alport syndrome, which, without proteinuria or renal impairment, allowed successful kidney donation. Conclusions: This case demonstrates that conservative pharmacological treatment for body weight reduction with GLP-1 receptor agonists may be an alternative to bariatric surgery for selected obese kidney donor candidates. The presented case highlights the importance of a multidisciplinary and personalized approach. Full article

This case study presents the long-term management of a 14-year-old male diagnosed with 18q deletion syndrome, also known as de Grouchy Syndrome, highlighting the challenges of treating rare chromosomal disorders in rural Romania. Background and Clinical Significance: 18q deletion syndrome, also known as de Grouchy syndrome, is a chromosomal disorder caused by the deletion of a part of the long arm of chromosome 18. This syndrome is seen in one out of 10,000 live births. The main features of the syndrome are short stature, hearing loss, hypotonia, mental retardation, endocrine disorders, and autoimmunity. Case Presentation: The patient’s condition was initially suspected at birth due to abnormal features and was later confirmed through genetic testing, revealing a 46,XY,del(18) karyotype. Key clinical features include craniofacial dysmorphism, delayed growth, congenital cardiac anomalies, developmental delay, severe neurological impairment, and multiple comorbidities such as endocrine dysfunction, dental anomalies, and orthopedic deformities. Despite early interventions such as cardiac surgery, the patient’s management has been challenged by limited access to specialized care. Conclusions: The case underscores the importance of timely genetic testing, early multidisciplinary care, and the role of family support in managing complex disorders. This report also addresses the gaps in healthcare accessibility in rural settings and emphasizes the need for improved infrastructure and genetic services. By comparing this case with the existing literature, the study explores the variability in clinical presentations of 18q deletion syndrome and advocates for more precise genetic testing to better understand its phenotypic spectrum. The patient’s ongoing challenges with medical and socio-economic factors emphasize the critical need for coordinated care and family support in managing rare genetic conditions. Full article

Background: Deep vein thrombosis (DVT) management remains challenging despite standard anticoagulation therapy. This study evaluated the comprehensive benefits of combining rivaroxaban with Aescuven (CAV) compared to rivaroxaban monotherapy (SAT) in DVT treatment. Methods: A retrospective analysis was conducted on DVT patients (2018–2023) using multi-method propensity score matching and ensemble weighting. Outcomes included improvement rate (IPR), daily improvement rate (DIR), cost-effectiveness ratio (CER), daily improvement cost (DIC), cost–LOS efficiency (CLE), and length of stay (LOS). Counterfactual analysis was implemented to estimate causal effects. Results: The CAV group demonstrated superior outcomes compared to SAT: IPR increased by 6.39 percentage points (95% CI: 5.61–7.39), DIC substantially reduced by 3323.38 CNY (95% CI: 2887.95–3758.81), and CLE improved by 136.97 CNY per day (95% CI: 122.31–151.64), with minimal LOS increase (0.15 days, 95% CI: 0.12–0.18). Network analysis revealed significant correlations between baseline coagulation parameters and treatment outcomes, particularly between APTT and economic benefits. Conclusions: The CAV regimen achieved significant clinical and economic advantages over standard monotherapy without substantially increasing resource utilization. These findings support integrating venoprotective agents into conventional anticoagulation strategies for optimized DVT management. Full article
