Studies that have sought to describe and account for pre-diagnosed depressive symptoms on BC treatment choice, delay in initiating treatment, and mortality have been inconsistent. The purpose of the study is to examine the association between pre-diagnosed depressive symptoms and their impact on breast cancer (BC) treatment, treatment delays, and mortality. We conducted a retrospective cohort study using the Surveillance, Epidemiology, and End Results–Medicare Health Outcomes Survey (SEER-MHOS) dataset among women aged 65 years and older diagnosed with BC. Among 3840 eligible patients, 28.1% had pre-diagnosed depressive symptoms. Patients with pre-diagnosed depressive symptoms who were diagnosed with early-stage BC were significantly more likely (OR = 1.52; 95% CI: 1.26–1.84) to undergo mastectomy or receive breast-conserving surgery (BCS) alone rather than BCS plus radiation therapy (RT) compared to patients who were not pre-diagnosed with depressive symptoms. Among patients with advanced-stage BC, pre-diagnosed depressive symptoms were not significantly associated with treatment type. Among Hispanic patients, pre-diagnosed depressive symptoms were associated with treatment delays. Overall, patients with pre-diagnosed depressive symptoms had a 16% increased adjusted risk of BC-related mortality compared to those who were not pre-diagnosed with depressive symptoms, and those with advanced-stage cancer had an 18% higher adjusted risk of death than early-stage BC. Conclusions: Overlooking depressive symptoms management prior to a breast cancer diagnosis may result in poorer survival outcomes. Early detection and consistent management of depression are critical for improving patient survival. Full article

Background: Mediastinal ectopic pancreas (EP) is an exceptionally rare entity that can mimic malignancy. Diagnosis is typically established post-operatively; pre-operative confirmation is challenging. Case Presentation: We describe a 28-year-old man presenting with life-threatening airway obstruction due to a progressive mediastinal mass, requiring emergency tracheal stenting. Diagnostic workup revealed a critical discordance: while CT-guided core biopsy confirmed benign ectopic pancreatic tissue, concurrent flow cytometry identified a monoclonal B-cell population with a high Ki-67 index (~86%), raising concern for a high-grade lymphoid process. However, no morphological evidence of lymphoma was found, and PET-CT showed only moderate metabolic activity (SUVmax 4.6), making an untreated aggressive lymphoma less consistent. The patient declined surgical resection. Management proceeded with a conservative strategy of structured clinical surveillance based on the benign histology. At 6-month follow-up, the patient remained clinically stable without chemotherapy, supporting the diagnosis of benign ectopic pancreas and suggesting the flow cytometric findings represented reactive “pseudo-monoclonality” secondary to inflammation. Conclusions: This case highlights mediastinal EP as a rare airway emergency and illustrates a major diagnostic pitfall: flow cytometric clonality and high proliferative fractions can occur in inflammatory settings and must not override benign architectural histology. When discordance persists and definitive tissue cannot be obtained, management should emphasize multidisciplinary review, deliberate specimen triage, and structured surveillance with predefined triggers for repeat higher-yield biopsy or surgical sampling and airway-stent reassessment.

Total hip arthroplasty (THA) is a widely performed procedure that significantly enhances patients’ quality of life. However, nerve injury remains a concerning complication, with an incidence ranging from 0.6% to 3.7%, depending on patient and surgical variables. This narrative review provides a comprehensive overview of nerve injuries associated with THA, focusing on etiology, risk factors, clinical manifestations, prevention, and treatment strategies. The most affected nerves include the sciatic, femoral, lateral femoral cutaneous (LFCN), superior gluteal, and obturator nerves. Anatomical factors such as developmental hip dysplasia (DDH), limb length discrepancy, and aberrant nerve courses, along with patient-specific conditions like female sex, obesity, and pre-existing spinal disorders, increase the risk of nerve damage. Surgical complexity, revision procedures, and surgeon experience also influence injury likelihood. Clinical manifestations range from sensory disturbances to motor deficits including foot drop, Trendelenburg gait, or impaired knee extension, depending on the nerve involved. Diagnosis is primarily clinical, supported by electrophysiological studies and imaging when needed. Prevention hinges on careful preoperative planning, appropriate surgical approach selection, meticulous intraoperative technique, and attention to limb positioning. Treatment is typically conservative, involving pain control, physical therapy, and neurostimulation. In refractory or severe cases, interventions such as nerve decompression, repair, or tendon transfer may be considered. Pharmacological agents including vitamin B12, tacrolimus, and melatonin show potential in promoting nerve regeneration. Although most nerve injuries resolve spontaneously or with conservative measures, some cases may result in long-term deficits. Understanding the mechanisms, risk factors, and management strategies is essential to mitigating complications and optimizing functional outcomes in patients undergoing THA. Full article

Pectus excavatum (PE) is the most frequent chest wall deformity, representing 65–95% of all cases, with an estimated prevalence of up to 1 in 300 births. Despite its frequency, it remains underrecognized in sports cardiology. PE results from sternal depression and narrowing of the anterior chest, which may lead to cardiac compression, impaired diastolic filling, and reduced stroke volume during exercise. Consequently, athletes with PE often present with cardiovascular symptoms such as exercise-induced dyspnoea, chest pain, palpitations, presyncope, or reduced physical fitness. Electrocardiographic changes, including right bundle branch block, axis deviation, atrial enlargement, T-wave inversion, QS complexes or Brugada phenocopies, are frequent and may mimic serious cardiovascular conditions, complicating pre-participation screening. Furthermore, PE is associated with potentially high-risk conditions including mitral valve prolapse, ventricular arrhythmias, and connective tissue disorders such as Marfan syndrome, which carry implications for sports eligibility and safety. Assessment of athletes with PE requires multimodal imaging (echocardiography, computed tomography, magnetic resonance), cardiopulmonary exercise testing, and exclusion of concomitant cardiovascular disease. Treatment strategies range from conservative approaches (physiotherapy, vacuum bell therapy) to surgical correction, most commonly with the Nuss procedure, which can improve cardiac function, exercise capacity, and quality of life. Management should involve shared decision making between clinicians, athletes, and families, weighing potential risks against athletic aspirations. Awareness of PE in sports cardiology is crucial, as it not only influences differential diagnosis and screening outcomes but also impacts career decisions and the psychological well-being of athletes.

Background and Clinical Significance: Granulomatous reactions are rare but clinically significant complications of aesthetic procedures involving dermal fillers, particularly in individuals with underlying immune dysregulation. These reactions present diagnostic and therapeutic challenges, especially when associated with undiagnosed or latent autoimmune diseases. This case illustrates the interaction between filler composition, immune status, and the risk of delayed inflammatory responses, underscoring the need for thorough patient evaluation and individualized management strategies. Case Presentation: A 49-year-old woman developed delayed-onset subcutaneous nodules following midface augmentation with two filler types: a monophasic, cross-linked hyaluronic acid gel (concentration 20 mg/mL, 1.0 mL per side) injected into the deep malar fat pads, and a calcium hydroxyapatite suspension (30% CaHA microspheres in a carboxymethylcellulose carrier, 0.5 mL per side) placed in the subdermal plane along the zygomatic arch. The procedure was performed in a single session using a 22 G blunt cannula, with no immediate adverse events. High-resolution ultrasound demonstrated hypoechoic inflammatory nodules without systemic symptoms. A retrospective review of her medical history revealed a latent, previously undisclosed diagnosis of granulomatosis with polyangiitis (GPA). The immune-adjuvant properties of calcium hydroxyapatite likely triggered a localized pro-inflammatory response in this predisposed patient. A conservative, staged, non-invasive therapeutic protocol—saline infiltration, intradermal polynucleotide injections, and manual lymphatic drainage—achieved complete clinical and radiological resolution without systemic immunosuppression or surgical intervention. Conclusions: This case highlights the critical importance of pre-procedural immunological assessment in aesthetic medicine. Subclinical autoimmune conditions may predispose patients to delayed granulomatous reactions after filler injections. An individualized, conservative management strategy can effectively resolve such complications while minimizing the risks associated with aggressive treatment. Greater awareness of immune-mediated responses to dermal fillers is essential to ensure patient safety and optimize clinical outcomes. Full article

Background/Objectives: The diagnosis of atypical endometrial hyperplasia (AEH) is associated with a high rate of concurrent endometrial cancer (EC). This occurrence can be particularly challenging in premenopausal women wishing to become pregnant, as they may be subjected to conservative treatment. The type of endometrial sampling may affect this outcome. Currently, the recommended type of endometrial sampling is under hysteroscopic guidance. There is scant literature regarding the reliability of hysteroscopically guided biopsy (HSC-bio) and hysteroscopic endometrial resection (HSC-res) on this topic. We aimed to assess the underestimation rate of EC in AEH, according to different hysteroscopic sampling methods. The secondary outcome was to evaluate the procedure performance in pre- and postmenopausal women. Methods: We conducted a multi-institutional retrospective study that included 536 women diagnosed with AEH who underwent hysterectomy between 2015 and 2020. Patients were divided into two groups based on the initial diagnostic approach for AEH: HSC-bio and HSC-res. The comparison was performed using univariate and multivariate analyses. Results: 160/536 women (29.9%) showed EC at hysterectomy. Overall, the following rate of EC underestimation was found: HSC-bio = 32.1%, HSC-res = 24.2%, p = 0.07. After adjusting for baseline characteristics using logistic regression analysis, overall, there was no significant association of EC underestimation according to the type of sampling procedure. Interestingly, in premenopausal women, including 161 cases, the rate of EC underestimation in HSC-bio and HSC-res was 28.8% vs. 14.0%, respectively (p = 0.034). Conclusions: There were no significant differences in EC underestimation between the two hysteroscopic procedures in the entire cohort of women with AEH. Limited to the secondary objective, the significant findings in premenopausal women may be of particular clinical interest, as this population may undergo conservative treatment. Full article

Background: Chronic thoracic pain is commonly caused by thoracic facet dysfunction, intercostal neuralgia, surgery, or thoracic pain secondary to cancer and is present in approximately 15% of the population. Conventional treatments, including pharmacotherapy and transcutaneous electrical nerve stimulation, are often ineffective and are often associated with poorly tolerated adverse effects. Cooled radiofrequency ablation (c-RFA) is a minimally invasive procedure that uses radiofrequency energy delivered through a probe to lesion the targeted nerve and provide significant and lasting relief. Methods: This study was a retrospective analysis of data extracted from UW-Health Electronic Medical Health records from October 2015 through June 2024. Patient data were collected, including diagnosis, pre-operative pain score, post-operative pain score, duration of relief, age, sex, and BMI. A two-tailed paired t-test was used to analyze the pre-operative and post-operative pain scores. A p-value < 0.05 was considered significant. Results: A total of 111 thoracic c-RFA procedures were reviewed; 43 were excluded due to absent pre-operative or post-operative pain scores in medical records. A total of 68 procedures were included in the analysis, comprising 55 patients: 25 females and 30 males with an average age of 51.31 ± 18.22 years and a BMI of 29.79 ± 6.48 kg/m². Improvement in pain scores was reported in 77.94% (n = 53), 16.18% (n = 11) reported no change, and 5.88% (n = 4) reported worsening pain. Patients reported an average pre-operative pain score of 5.98 (M = 5.98, SD = 1.91) and an average post-operative pain score of 3.06 (M = 3.06, SD = 2.52); this achieved significance (p < 0.0001). Of the 77.94% (n = 53) charts that noted improvement, there is an average of 62.83 ± 28.48% reduction from their pre-operative pain scores. The average duration of relief lasted 11.85 ± 13.42 months. Conclusions: This study supports the efficacy and safety of c-RFA as a minimally invasive therapy for chronic thoracic pain refractory to conservative measures. Full article

Morel-Lavallée lesions (MLLs) in the knee are rare. This article presents one of the largest documented cases (13.46 × 12.73 × 3.03 cm), successfully managed non-operatively with clinical and sonographic follow-up. The patient was a 19-year-old male who sustained a bike accident, presenting with immediate gross swelling over the anterior knee, along with bruising and skin abrasions. He was unable to walk and was admitted to the orthopedic ward. A bedside handheld ultrasound examination revealed a large pre-patellar MLL, primarily filled with blood clots. Ultrasound-guided aspiration resulted in a dry tap. The diagnosis was confirmed through magnetic resonance imaging, and conservative management was implemented. At four weeks post-injury, the patient showed significant improvement. He achieved full range of knee motion seven weeks post-injury. Ultrasound imaging revealed a significantly reduced lesion size, with a sub-centimeter thickness. This case highlights the pivotal role of portable ultrasound in the acute diagnosis and follow-up of MLLs. It also demonstrates that, even with a lesion of substantial size, non-operative treatment can be highly effective. These findings provide valuable insights for developing treatment protocols for this rare condition. Full article

Background/Objectives: Ventricular pre-excitation (VP) increases the risk of sudden cardiac death among children. While transcatheter ablation could potentially be therapeutic, it is not without risk, especially in smaller children. Accessory pathways (APs) may spontaneously lose anterograde conduction properties over time, making invasive treatment unnecessary. We aim to investigate the probability of spontaneous loss of VP during childhood, as well as the potential factors that may be associated with VP resolution. Methods: We conducted a retrospective study of patients with VP diagnosed before 12 years of age and referred to two Northern Italian tertiary care hospitals between 1993 and 2021. Patients with complex congenital heart disease were excluded. Our primary objective was to determine the likelihood of spontaneous resolution of VP. Results: Overall, 153 patients were included, with a median age at first diagnosis of 4.9 years (25th–75th percentile: 75 days–8.4 years) and a median follow-up of 4.9 years (25th–75th percentile: 1.8–8 years). Through left truncated Kaplan–Meier analysis, we estimated that anterograde conduction would persist in 53% and 33.8% of patients at the age of 1 and 16 years, respectively. Our findings revealed that the absence of symptoms and intermittent VP were associated with a higher likelihood of VP resolution. It is noteworthy that no major arrhythmic events were reported. Conclusions: Our study strongly supports the implementation of a conservative strategy in younger children with VP. Our findings indicate that a significant proportion of pediatric patients may experience spontaneous resolution of VP in the early years of their lives, making any invasive treatment unnecessary.

Introduction: Breast cancer (BC) is a disease that affects about 2.2 million people worldwide. The prognosis and treatment of these patients depend on clinical and histopathologic staging, in which more aggressive cancers need a less conservative therapeutic approach. Previous studies showed that patients with BC have an increased frequency of systemic microvesicles (MVs) that are associated with invasion, progression, and metastasis, which can be used in liquid biopsy to predict the therapeutic response in individualized treatment. Objective: This study proposes the development of a minimally invasive BC diagnostic panel and follow-up biomarkers as a complementary method to screen patients. Methods: The quantification of circulating MVs in 48 healthy women and 100 BC patients who attended the Mário Penna Institute between 2019 and 2022 was performed by flow cytometry. In addition, the MVs of BC patients were analyzed before treatment and 6, 12, and 24 months post-treatment. Machine learning approaches were employed to determine the performance of MVs to identify BC and to propose BC classifier algorithms. Results: Patients with BC had more neutrophil- and endothelial cell-derived MVs than controls before treatment. After treatment, all MV populations were decreased compared to pre-treatment, but leukocyte- and erythrocyte-derived MVs were increased at 12 months after treatment, before decreasing again at 24 months. Conclusions: Performance analyses and machine learning approaches pointed out that MVs from neutrophils and endothelial cells are the best candidates for BC diagnostic biomarkers. Neutrophil- and endothelial cell-derived MVs are putative candidates for BC biomarkers to be employed as screening tests for BC diagnosis. Full article

In pregnancies with vasa previa, prenatal diagnosis and pre-labor cesarean delivery are associated with significantly improved perinatal outcomes compared to undetected cases. However, a universally accepted ultrasonographic definition of vasa previa is lacking. Specifically, the distance from the cervical internal os beyond which vaginal delivery can be safely recommended remains to be determined. Field experts and recently published societal guidelines agree that a 2 cm cut-off is suboptimal, given that complete cervical dilation during labor risks unprotected fetal vessels within a 5 cm radius from the internal os. Thus, in the setting of a scarcity of evidence and case reports of perinatal death with unprotected fetal vessels beyond 2 cm from the internal os, a more conservative definition that includes unprotected fetal vessels located within 5 cm of the internal os is imperative to improve outcomes.

Objectives: Pneumatosis intestinalis (PI) is rare in childhood. The aetiology remains poorly understood. Our aim was to assess its associated risk factors and outcome. Methods: Retrospective data collection of all children (>1 month of age) with radiological evidence of PI identified from 1991 to 2021 in a large children’s hospital. Poor outcome was defined as loss of enteral autonomy, or death within one month of PI diagnosis. Results: A total of 31 patients (21 male, 67.7%) were included, with a median age of 5 years. The underlying diagnosis was heterogenous. Cerebral palsy and acute lymphocytic leukaemia (ALL) were most common (5/31 for each, 16.13%). A share of 12/31 (38.7%) developed PI 2–15 months post-bone marrow transplantation (BMT). Most patients (n = 15, 48.4%) had no pre-existing gastroenterological disorder. In the majority (11/31, 35.5%), PI was an incidental finding. Abdominal pain was the most common presentation in symptomatic children (7/31, 22.6%). All (31/31, 100%) were managed conservatively with gut rest and antibiotics, and 6/31 (19.4%) had a poor outcome (1/31 permanent feeding intolerance, 5/31 died). When comparing patients who did well (group 1) to those with a poor outcome (group 2), worse prognosis was associated with a lower platelet count (p = 0.016), raised CRP (p = 0.008), higher creatinine (p = 0.006), and higher urea (p = 0.013). Conclusions: The overall prognosis of PI in childhood is good but associated with significant morbidity and mortality in a small number of patients. Our data suggest that lower platelet count, and higher urea, creatinine, and CRP levels might be risk factors. Full article

Background: The COVID-19 pandemic has significantly affected breast cancer patients by causing delays in diagnosis and treatment processes. This study aims to investigate the effects of the pandemic on the treatment process and short-term outcomes of breast cancer patients. Methods: This retrospective, cross-sectional, single-center study included 414 patients who underwent surgery for breast cancer at the Inonu University General Surgery Clinic between March 2018 and June 2021. The patients were divided into two groups: pre-pandemic (Pre-COVID-19; n = 240) and pandemic (COVID-19 Era; n = 174) periods. The groups were compared in terms of demographic, clinical, and histopathological variables. Results: During the pandemic period, the use of neoadjuvant therapy (from 21.3% to 34.5%) and preoperative PET-CT imaging (from 80.4% to 90.8%) rates increased, while breast-conserving surgery (from 27.9% to 19.0%) and the presence of comorbid diseases (from 45.0% to 29.9%) decreased significantly. While there was no significant difference between the groups in terms of the time from diagnosis to surgery (25 vs. 28.5 days, p = 0.121), the time to report the pathology result after surgery decreased during the pandemic period (28 vs. 23 days, p < 0.001). There was no significant difference between the groups in terms of immunohistochemical (ER, PR, Ki-67, E-cadherin, and c-erbB2), histopathological (lymphovascular invasion, perineural invasion, comedo necrosis, modified Bloom–Richardson grade, and TNM classification), and clinical (recurrence, metastasis, and axillary lymph node metastasis) features of the tumor. The mortality rate in the Pre-COVID-19 group (7.1%) was significantly higher than in the COVID-19 Era group (2.3%) (p = 0.049). Finally, in terms of the survival analysis, a statistically significant difference was found between the Pre-COVID-19 and COVID-19 Era groups in terms of the mean follow-up duration of the patients (p = 0.044). Conclusions: The study results show that the use of neoadjuvant therapy and radical surgery preference increased in breast cancer treatment during the pandemic period, but there was no significant change in tumor biology and histopathological features. Breast-conserving surgery rates, comorbidity rates, and pathology reporting times were significantly shortened. Long-term follow-up periods of 3 and 5 years are needed to see the impact of the pandemic on breast cancer patients. Full article

Introduction: This study hypothesized that changes in the elasticity of the quadriceps and patellar tendons before and after the diagnosis of patellar tendinopathy would correlate with the range of motion (ROM) following conservative treatment. We aimed to prospectively assess post-treatment ROM using multinomial logistic regression, incorporating elasticity measurements obtained via shear wave elastography (SWE). Materials and Methods: From March 2023 to April 2024, 95 patients (86 men; aged 20–45 years, mean 25.62 ± 5.49 years) underwent SWE preoperatively and two days post-diagnosis of patellar tendinopathy. Elasticity measurements of the rectus femoris, vastus medialis, vastus lateralis, patellar tendon, and biceps tendon were obtained during full flexion and extension. Based on ROM 56 days post-treatment, patients were categorized into two groups: Group A (ROM > 120 degrees) and Group B (ROM < 120 degrees). A multinomial logistic regression algorithm was employed to classify the groups using patient information and tendon elasticity measurements both at diagnosis and 1-week post-diagnosis. Results: The predictive accuracy using only patient information was 62%, while using only elasticity measurements yielded 68% accuracy. When combining patient information with elasticity measurements taken at diagnosis and two days post-diagnosis, the algorithm achieved an accuracy of 79%, sensitivity of 92%, and specificity of 56%. Conclusions: The combination of patient information and tendon elasticity measurements obtained via SWE at pre-conservative treatment and early post-conservative treatment periods effectively predicts post-treatment ROM. This algorithm can guide rehabilitation strategies for soldiers with patellar tendinopathy. Full article

Background: Prostate cancer is the second most common new cancer diagnosis in the United States. It is usually slow-growing, and when it is low-grade and confined to the prostate gland, it can be treated either conservatively (through active surveillance) or with surgery. However, if the cancer has spread beyond the prostate, such as to the lymph nodes, then that indicates a more aggressive cancer, and surgery may not be adequate. Methods: The challenge is that it is often difficult for radiologists reading prostate-specific imaging such as magnetic resonance images (MRIs) to differentiate malignant lymph nodes from non-malignant ones. An emerging field is the development of artificial intelligence (AI) models, including machine learning and deep learning, for medical imaging to assist in diagnostic tasks. Earlier research focused on implementing texture algorithms to extract imaging features used in classification models. More recently, researchers began studying the use of deep learning for both stand-alone feature extraction and end-to-end classification tasks. In order to tackle the challenges inherent in small datasets, this study was designed as a scalable hybrid framework utilizing pre-trained ResNet-18, a deep learning model, to extract features that were subsequently fed into a machine learning classifier to automatically identify malignant lymph nodes in patients with prostate cancer. For comparison, two texture algorithms were implemented, namely the gray-level co-occurrence matrix (GLCM) and Gabor. Results: Using an institutional prostate lymph node dataset (42 positives, 84 negatives), the proposed framework achieved an accuracy of 76.19%, a sensitivity of 79.76%, and a specificity of 69.05%. Using GLCM features, the classification achieved an accuracy of 61.90%, a sensitivity of 74.07%, and a specificity of 42.86%. Using Gabor features, the classification achieved an accuracy of 65.08%, a sensitivity of 73.47%, and a specificity of 52.50%. Conclusions: Our results demonstrate that a hybrid approach, i.e., using a pre-trainined deep learning model for feature extraction, followed by a machine learning classifier, is a viable solution. This hybrid approach is especially useful in medical-imaging-based applications with small datasets. Full article
