Background and Clinical Significance: Serratus Anterior Muscle Pain Syndrome (SAMPS) is an underdiagnosed cause of anterior chest wall pain, often attributed to myofascial trigger points of the serratus anterior muscle (SAM) or dysfunction of the Long Thoracic Nerve (LTN), leading to significant disability and affecting ipsilateral upper limb movement and quality of life. Current diagnosis relies on exclusion and physical examination, with limited treatment options beyond conservative approaches. This case report presents a novel approach to chronic SAMPS, successfully diagnosed using Sonoguided Digital Palpation (SDP) and treated with ultrasound-guided hydrodissection of the LTN using 5% dextrose in water (D5W) without local anesthetic (LA), in a patient where conventional treatments had failed. Case Presentation: A 72-year-old male presented with a three-year history of persistent left chest pain radiating to the upper back, exacerbated by activity and mimicking cardiac pain. His medical history included two percutaneous coronary interventions. Physical examination revealed tenderness along the anterior axillary line and a positive hyperirritable spot at the mid axillary line at the 5th rib level. SDP was used to visualize the serratus anterior fascia (SAF) and LTN, and to reproduce the patient’s concordant pain by palpating the LTN. Ultrasound-guided hydrodissection of the LTN was then performed using 20–30cc of D5W without LA to separate the nerve from the surrounding tissues, employing a “fascial unzipping” technique. The patient reported immediate pain relief post-procedure, with the pain reducing from 9/10 to 1/10 on the Numeric Rating Scale (NRS), and sustained relief and functional improvement at the 12-month follow-up. Conclusions: Sonoguided Digital Palpation (SDP) of the LTN can serve as a valuable diagnostic adjunct for visualizing and diagnosing SAMPS. Ultrasound-guided hydrodissection of the LTN with D5W without LA may provide a promising and safe treatment option for patients with chronic SAMPS refractory to conservative management, resulting in rapid and sustained pain relief. Further research, including controlled trials, is warranted to evaluate the long-term efficacy and generalizability of these findings and to compare D5W to other injectates. Full article

Background and Clinical Significance: Spontaneous renal hematoma, also known as Wunderlich syndrome (WS), is a rare disease characterized by the acute onset of spontaneous renal hemorrhage into the subcapsular, perirenal, and/or pararenal spaces without a history of prior trauma. WS can be a life-threatening condition due to hemorrhagic shock; consequently, prompt diagnosis and a therapeutic approach are essential for favorable outcomes. Treatment ranges from conservative management to surgical intervention. The most common etiologies are neoplasms and vascular diseases, but WS can also be observed in patients undergoing hemodialysis. In patients with end-stage renal disease (ESRD), especially those on hemodialysis, acquired cystic kidney disease and renal cell carcinoma are among the primary causes of WS. Although less common, WS can develop in dialysis patients even in the absence of traditional (primary) risk factors. In general, patients with chronic kidney disease (CKD) have a paradoxical hemostatic profile, likely explaining their higher tendency to bleed, so WS can occur without existing predisposing factors. The multifactorial pathogenesis in these patients includes functional platelet abnormalities, intimal arterial fibrosis, chronic inflammation, and oxidative stress associated with ESRD. The use of hemodialysis-related antithrombotic medications could serve as another contributing factor increasing the risk of bleeding. Case Presentation: We present a case report of a 62-year-old male on chronic dialysis who developed sudden right-sided lumbar pain and hematuria during dialysis without evidence of prior trauma. Imaging revealed a large subcapsular hematoma of the right kidney. Further investigations did not reveal additional risk factors in this instance; however, his routinely used hemodialysis-related antithrombotic medications were potentially a contributing factor. Despite conservative treatment, his condition worsened, and the hematoma enlarged, requiring emergency nephrectomy. Postoperatively, his condition gradually improved. Conclusions: This case highlights the importance of considering WS in hemodialysis patients, even without the presence of traditional risk factors, as well as including WS in the differential diagnosis of acute abdominal pain.

Background: Chronic primary orofacial pain (COFP) affects approximately 7% of the population and often leads to reduced quality of life. Patients frequently undergo multiple assessments and treatments across healthcare disciplines, often without a definitive diagnosis. The 2019 ICD-11 classification of chronic primary pain clusters together COFP subtypes based on chronicity and associated functional and emotional impairment. Objective: This study aimed to evaluate whether these subtypes of COFP share common underlying mechanisms by comparing neuroimaging findings. Methods: A systematic review was conducted in accordance with PRISMA guidelines. Searches were performed using Medline (OVID) and Scopus up to April 2025. Inclusion criteria focused on MRI-based neuroimaging studies of participants diagnosed with COFP subtypes. Data extraction included participant demographics, imaging modality, brain regions affected, and pain assessment tools. Quality assessment used a modified Coleman methodological score. Results: Fourteen studies met the inclusion criteria, all utilising MRI and including two COFP subtypes (temporomandibular disorder and burning mouth syndrome). Resting- and task-state imaging revealed overlapping alterations in several brain regions, including the thalamus, somatosensory cortices (S1, S2), cingulate cortex, insula, prefrontal cortex, basal ganglia, medial temporal lobe, and primary motor area. These changes were consistent across both TMD and BMS populations. Conclusions: The findings suggest that chronic primary orofacial pain conditions (TMD and BMS) may share common central neuroplastic changes, supporting the hypothesis of a unified pathophysiological mechanism. This has implications for improving diagnosis and treatment strategies, potentially leading to more targeted and effective care for these patients. Full article

Background and Objectives: Visceral arterial pseudoaneurysms (VAPAs) are rare vascular lesions characterized by the disruption of partial disruption of the arterial wall, most commonly involving the intima and media. They have an estimated incidence of 0.1–0.2%, with the splenic artery most commonly affected. Their management poses unique challenges due to the high risk of rupture. Timely recognition is crucial, as unmanaged pseudoaneurysms have a mortality rate of 90%. This narrative review aims to synthesize current knowledge regarding the epidemiology, etiology, clinical presentation, diagnostic methods, and management strategies for VAPAs. Materials and Methods: A literature search was performed across Pubmed for articles reporting on VAPAs, including case reports, review articles, and cohort studies, with inclusion of manuscripts that were up to (date). VAPAs are grouped by embryological origin—foregut, midgut, and hindgut. Results: Chronic pancreatitis is a primary cause of VAPAs, with the splenic artery being involved in 60–65% of cases. Other causes include acute pancreatitis, as well as iatrogenic trauma from surgeries, trauma, infections, drug use, and vascular diseases. VAPAs often present as abdominal pain upon rupture, with symptoms like nausea, vomiting, and gastrointestinal hemorrhage. Unruptured pseudoaneurysms may manifest as pulsatile masses or bruits but are frequently asymptomatic and discovered incidentally. Diagnosis relies on both non-invasive imaging techniques, such as CT angiography and Doppler ultrasound, and invasive methods like digital subtraction angiography, which remains the gold standard for detailed evaluation and treatment. A range of management options exists that are tailored to individual cases based on the aneurysm’s characteristics and patient-specific factors. This encompasses both surgical and endovascular approaches, with a growing preference for minimally invasive techniques due to lower associated morbidity. Conclusions: VAPAs are a critical condition requiring prompt early recognition and intervention. This review highlights the need for ongoing research to improve diagnostic accuracy and refine treatment protocols, enhancing patient outcomes in this challenging domain of vascular surgery.

Background: Endometriosis is a chronic gynecological condition marked by ectopic endometrial-like tissue, leading to inflammation, pain, and infertility. Diagnosis is often delayed by up to 10 years. Identifying non-invasive biomarkers could facilitate earlier detection. MicroRNAs, known for their stability in biological fluids and role in disease processes, have emerged as potential diagnostic tools. This pilot study investigated whether serum miRNA profiling can differentiate endometriosis from other causes of chronic pelvic pain. Methods: Serum samples from 52 patients (36 with laparoscopically confirmed endometriosis and 16 controls) treated for chronic pelvic pain at a University Endometriosis Centre were analyzed. High-throughput miRNA sequencing was performed. Feature selection reduced 4285 miRNAs to the 20 most informative MiRNAs. Machine learning models, including logistic regression, decision tree, random forest, and support vector machine, were trained and evaluated. Results: Among the tested machine learning models, support vector machine achieved the best overall performance (accuracy 0.71, precision 0.80), while logistic regression and random forest showed the highest AUC values (0.84 and 0.81, respectively), indicating strong diagnostic potential of serum miRNA profiling. Conclusions: This study demonstrates the feasibility of using serum miRNA profiling combined with machine learning for the non-invasive classification of endometriosis. The identified miRNA signature shows strong diagnostic potential and could contribute to earlier and more accurate detection of the disease. Full article

Background: Bertolotti syndrome describes a painful lumbosacral transitional vertebra (LSTV) with a pseudoarticulation between an enlarged lateral process of the caudal lumbar vertebra (L5) and ilium or sacrum. It often presents with chronic lower back pain with or without radiculopathy. The current literature emphasizes Bertolotti as a differential diagnosis in young adults. However, it is presumably underdiagnosed in middle-aged and older patients. Treatment ranges from conservative treatment with physiotherapy, infiltration, and radiofrequency ablation to surgical interventions. Case Description: In this case illustration, we present the diagnostic and therapeutic challenges in a 48-year-old female triathlete with persistent left gluteal pain caused by Bertolotti syndrome. When conservative treatment with physiotherapy, infiltrations, thermocoagulation, and radiofrequency ablation of the pseudoarticulation failed, microsurgical reduction of the hypertrophic transverse process was performed. This minimally invasive intervention achieved satisfactory pain relief of at least 70% one year after surgery, allowing the patient to resume her athletic activities. Conclusions: Bertolotti syndrome should be considered a potential differential diagnosis in patients of all ages. Since many patients endure years of misdiagnosis, adequate treatment is crucial upon diagnosis. If conservative measures fail, surgical treatment such as “processectomy” or spinal fusion should be evaluated. This case follows the CARE reporting guidelines. Full article

Background/Objectives: Chronic Pelvic Pain (CPP) is a multifactorial condition that affects in many ways the daily life of patients suffering from it. Different psychological factors demonstrated to be associated with the genesis and maintenance of CPP. Less is known about the role of the Psychological Flexibility (PF) model. Thus, the aim of this study is to explore the relationship between the PF domains, psychological distress, pain, and quality of life in patients with chronic pelvic pain. Methods: A total of 114 women with a diagnosis of chronic pelvic pain were included in this study. Participants completed online self-report measures to assess psychological distress (anxiety, depression, stress), Psychological Flexibility, Pain interference, and Quality of life. Results: Psychological distress and Psychological Flexibility showed significant association with pain interference. Other PF dimensions related to pain interference were as follows: self as context, defusion, and values. Physical Quality of life showed significant association with Experiential avoidance and Lack of values clarity, while Mental Quality of life was associated with Psychological Inflexibility and Self as content. Conclusions: Psychological distress and Psychological Flexibility have a role in pain perception and its interference with a patient’s daily life, affecting also physical and mental quality of life of CPP patients.

Background: Chronic low back pain (CLBP) is the leading cause of disability both within the United States and globally. However, reliable diagnosis and treatment remains limited due to a lack of objective and image-based biomarkers. Modic changes (MCs) are visible vertebral endplate and bone marrow changes in signal intensity seen on MRI. MCs have emerged as promising correlates with degenerative disc disease and CLBP. Methods: This is a non-systematic literature review. Results: This review synthesizes current evidence on the classification, pathophysiology, and imaging of MCs, with a particular focus on their associations with patient-reported outcomes, including pain (Visual Analog Scale), functional status (Oswestry disability index and Roland-Morris Disability Questionnaire), and health-related quality of life (Short Form-36 and EuroQol 5-Dimension 5 Level). MC type 1 and 2 show significant correlations with symptom severity and predict positive response to basi-vertebral nerve (BVN) ablation, a minimally invasive intervention inhibiting the nerves’ ability to transmit pain signals. Conclusions: Across multiple trials, BVN ablation has shown significant sustained improvements in patient-reported outcomes among patients with MC, reinforcing their role as both a diagnostic and therapeutic biomarker.

Background: Lipedema is a chronic disease of subcutaneous adipose tissue that predominantly affects women and is frequently associated with endocrinopathies such as insulin resistance and obesity. Its pathogenesis is still unclear, and treatment, which requires a multi-disciplinary approach, is prolonged over time and is not always effective. There is currently no drug treatment available for this disease. Methods: Five different cases of women with lipedema and insulin resistance, treated with Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RAs) and once-weekly exenatide, in association or not with lifestyle changes (diet or physical activity) for 3 to 6 months are described. Changes in anthropometric parameters, symptoms, clinical findings and the thickness of superficial adipose tissue measured by ultrasound were evaluated. Results: Treatment with exenatide, whether combined with a change in diet or physical activity, resulted in a reduction in the characteristic symptoms of lipedema, in pain evoked by pinching the adipose tissue fold and in the thickness of subcutaneous adipose tissue at the levels of the lower limbs, abdomen and upper limbs. In four out of five cases, a reduction in body weight was observed, particularly during the first three months of treatment and in cases with greater metabolic impairment. Clinical, instrumental and subjective improvements were also observed in cases where there was no reduction in body weight and in patients who had previously undergone lower limb liposuction. Conclusions: The improvement in symptoms and clinical signs of lipedema, in addition to the reduction in adipose tissue in patients with lipedema and insulin resistance with exenatide, suggests a novel pharmacological approach to the disease, which can be combined with other conservative and surgical treatments to promote weight reduction. These results also highlight the association of this disease with metabolic alterations and the fundamental role of an accurate diagnosis followed by the treatment of comorbidities and excess weight in these patients.

Opioid use in patients with sleep disordered breathing (SDB) presents therapeutic challenges within chronic pain and sleep medicine. Opioids impair respiratory drive through μ-opioid receptor activation in brainstem respiratory centers, exacerbating both obstructive and central apneas. Chronic opioid use is also linked to a high prevalence of central sleep apnea and increased nocturnal hypoventilation. Simultaneously, SDB contributes to heightened pain sensitivity via intermittent hypoxia, systemic inflammation, and alterations in neural plasticity. These mechanisms may influence opioid efficacy and dosing requirements. This review summarizes current evidence on how SDB and opioid use interact, emphasizing chronic opioid use in the setting of chronic pain management. We discuss the underlying mechanisms, clinical impacts, and potential avenues for enhanced diagnosis and therapy in this population. We conclude that the intersection of SDB and opioid use presents a complex clinical challenge that demands a multidisciplinary approach. Enhanced screening, personalized pharmacologic strategies, and integration of advanced diagnostics are essential for mitigating risks and optimizing care. Future research should focus on mechanistic studies and interventional trials to guide evidence-based management of this high-risk population. Full article

Endometriosis is a chronic inflammatory disease characterized by the presence of ectopic endometrial tissue, mainly in the pelvic cavity. It primarily affects women of reproductive age and is associated with significant morbidity, particularly chronic pelvic pain and infertility. Despite its high prevalence, diagnosis is often delayed, contributing to prolonged suffering and increased healthcare burden. This review examines the management of endometriosis in Primary Care, focusing on clinical presentation, risk factors, diagnostic approaches, and therapeutic options. A comprehensive bibliographic search was conducted using PubMed, Scopus, and Uptodate, including evidence-based clinical guidelines and literature up to January 2025. Women diagnosed with endometriosis in Primary Care are typically of reproductive age, with symptoms including dysmenorrhea, dyspareunia, and abnormal uterine bleeding. Risk factors include early menarche, low birth weight, short menstrual cycles, and family history. Transvaginal ultrasound is the recommended first-line imaging tool. Treatment includes analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), and hormonal therapies such as combined oral contraceptives or progestins. Non-pharmacological interventions, including dietary modifications and psychological support, are also relevant. Early identification in Primary Care is key to improving out-comes. Enhancing awareness among healthcare providers and promoting multidisciplinary management are essential to optimize care and reduce diagnostic delays. Full article

Background: Multiple myeloma (MM) is a heterogeneous plasma cell malignancy with non-specific symptoms and disease heterogeneity at clinical and biological levels. This non-specific set of symptoms, including bone pain, anemia, renal failure, hypercalcemia, and neuropathy, can mislead diagnosis as chronic or benign conditions, resulting in a delay in diagnosis. Timely identification is paramount to prevent organ damage and reduce morbidity. Methods: In this review, we present an overview of recent literature concerning the factors leading to the delayed diagnosis of MM and the impact of delayed diagnosis. This includes factors relevant to physicians and systems, diagnostic processes, primary healthcare services, and laboratory and imaging data access and interpretation. Other emerging technologies to diagnose NCIs include AI-based decision support systems and biomarker-focused strategies. Findings: Delayed diagnosis can lead to presentation at advanced disease stages associated with life-threatening complications and shorter progression-free survival. Patients are often seen by many physicians before they are referred to hematology. Understanding of clinical red flags for MM in primary care is inadequate. Our findings indicate that limited access to diagnostic tests, inconsistent follow-up of MGUS/SMM patients, and a lack of interdepartmental coordination delay the diagnostic process. Conclusions: Multimodal tools for early diagnosis of MM. Educational campaigns to raise awareness of the disease, algorithms dedicated to routine care and novel technologies, including AI and big data analytics, and new biomarkers may serve this purpose, as well as genomic approaches to the premalignant MGUS stage.

Clinical mastitis in small ruminants is usually seen with an incidence of less than 5% and most cases, especially with hyperacute evolution, are not referred for hospital care. During the 5-year survey, 16 goats and 7 sheep, totaling 23 small ruminants, met the inclusion criteria with a definitive diagnosis of clinical mastitis. Clinical signs ranged greatly among cases, varying from septic state in hyperacute cases, and enlarged, pendulous udder associated with chronic pain and abnormal gait in chronic cases. Microbiological culture revealed a wide array of bacterial pathogens, including Staphylococcus aureus, Escherichia coli, Streptococcus spp., and Pasteurella spp. In vitro antimicrobial susceptibility profiles varied greatly among bacteria isolates, ranging from sensitive to all tested antimicrobials to a multi-resistant profile. Pathological features included hyperemia and dark red areas of necrosis in the skin, marked hyperemia of the affected gland at the cut surface, lactiferous ducts and gland cisterns filled by cloudy or suppurative fluid, abscesses, and hardness of the mammary gland parenchyma. This retrospective study highlights the multifactorial nature and clinical variability of mastitis in small ruminants, demonstrating its significant impact on animal health, welfare, and production.

Systemic autoimmune rheumatic diseases (SARDs), such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Sjögren’s syndrome (SS), are traditionally characterized by chronic inflammation and immune-mediated damage to joints and other tissues. However, many patients also experience symptoms such as widespread pain, persistent fatigue, cognitive dysfunction, and autonomic disturbances that cannot be attributed directly or entirely to peripheral inflammation or structural pathology. These conditions suggest the involvement of interactions between the nervous and immune systems, which probably include both peripheral and central components. This review summarizes the current knowledge of neurological and neuroimmune mechanisms that may contribute to these symptoms in SARDs. Glial cell activation and neuroinflammation within the central nervous system (CNS), small-fiber neuropathy (SFN) affecting peripheral nociceptive pathways, central pain sensitization, and autonomic nervous system dysfunction will be discussed. In addition, the role of molecular mediators, including cytokines, neuropeptides, and microRNAs, that could potentially modulate neuroimmune signaling will be highlighted. Integrating findings from pathology, immunology, and neuroscience, this review seeks to provide a useful framework for understanding neuroimmune dysregulation in SARDs. It also highlights the clinical relevance of these mechanisms and summarizes new directions for diagnosis and treatment. Full article

Temporomandibular disorders (TMDs) impact quality of life and present diagnostic and treatment challenges. Biomarkers may serve as an additional tool to support diagnosis and monitor disease progression, offering supplementary information for treatment strategies in specific and selected patients. This systematic review aimed to assess the role of biomarkers in diagnosing TMD and guiding personalized treatment. It also examined key biomarkers linked to chronic temporomandibular joint (TMJ) pain and how therapies affect biomarker levels and clinical outcomes. A comprehensive search was conducted in PubMed, Scopus, and Web of Science to identify observational and interventional studies assessing the role of biomarkers in synovial fluid/tissue, saliva, and blood. The research was registered in PROSPERO, adhered to PRISMA guidelines, and employed Cochrane Risk of Bias tools. To assess the effect, only studies examining biomarker levels were considered. A total of forty-six studies met the inclusion criteria: three randomized controlled trials were rated as having some concerns, as were most of the observational studies. Elevated levels of interleukins (1ß and 6), tumour necrosis factor alpha, and prostaglandin E2 in synovial fluid were correlated with temporomandibular joint (TMJ) inflammation. Increased matrix metalloproteinases (2, 7, and 9) indicated cartilage deterioration, while oxidative stress markers such as malondialdehyde were higher in TMD patients. Treatments including hyaluronic acid, platelet-rich plasma, and low-level laser therapy effectively reduced inflammatory biomarkers and improved symptoms. Biomarkers show potential to contribute to the understanding of pathophysiological mechanisms in TMD and may support future diagnostic and therapeutic strategies for selected patients. After high-quality studies confirm these findings, this approach will enable personalized medicine by tailoring treatments to individual patient profiles, ultimately leading to improved outcomes and quality of life.
