Patellar pathologies are a common cause of knee dysfunction, with Patellofemoral Pain Syndrome (PFPS) alone responsible for 25% of knee-related visits to sports medicine clinics. Non-traumatic conditions, while often overlooked, can also lead to significant discomfort and functional limitations, highlighting the importance of accurate and timely diagnosis for effective management and prevention of complications. This pictorial review examines the radiologic characteristics of various non-traumatic patellar disorders, focusing on imaging modalities such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI).

Background: Papillary thyroid carcinoma (PTC) is the predominant form of thyroid cancer, and the presence of extrathyroidal extension (ETE) significantly impacts treatment decisions and prognosis. Accurate preoperative detection of ETE remains challenging, highlighting the need to evaluate advanced imaging techniques.This systematic review and meta-analysis aimed to investigate the diagnostic accuracy of magnetic resonance imaging (MRI) in detecting extrathyroidal extension (ETE) among patients diagnosed with papillary thyroid carcinoma (PTC).

Objective: To describe the clinical presentations and radiological manifestations of Erdheim-Chester disease (ECD) in the extremities, with particular emphasis on radiologic findings, as radiographs are typically the initial imaging modality used in clinical practice.

Methods: Following the PRISMA guidelines, a comprehensive systematic search was performed across Scopus, PubMed, Web of Science, and Embase databases, covering case reports from inception until August 1, 2024. Included were studies with pathologically confirmed ECD (CD68 positive and CD1a negative) that were evaluated with at least one imaging modality and provided detailed descriptions of radiological findings.

Placenta percreta, a rare variant of placenta accreta spectrum (PAS) disorders, poses a significant risk of life-threatening hemorrhage associated with the adherent placenta. Bladder involvement signifies an even rarer incidence and may sometimes present solely with gross hematuria. Therefore, it is imperative to consider both microscopic and gross hematuria during pregnancy as alarming signs.

Article Synopsis
  • First-degree relatives (FDRs) of celiac disease (CeD) patients are at a higher risk of developing the condition, with a systematic review analyzing the prevalence and symptoms using the anti-tissue transglutaminase antibody test.
  • From 34 studies involving over 10,000 FDRs, the research found a seroprevalence of 11% and a biopsy-confirmed prevalence of 7%, with daughters and sisters showing the highest rates.
  • The study suggests that about 1 in 14 FDRs may have CeD, emphasizing the need for routine screening to aid in early detection and management of the disease.

Objective: To evaluate the diagnostic performance of Machine Learning (ML) and Deep Learning (DL) models for predicting preoperative Lymph Node Metastasis (LNM) in Colorectal Cancer (CRC) patients.

Methods: A systematic review and meta-analysis were conducted following PRISMA-DTA and AMSTAR-2 guidelines. We searched PubMed, Web of Science, Embase, and Cochrane Library databases until February 16, 2024.

Background: Glioblastoma multiforme (GBM) poses a significant health challenge as the most common primary malignancy of the adult central nervous system. Gender- and age-related differences in GBM influence prognosis and treatment complexities. This multicenter retrospective study explores gender and age disparities in GBM patients, investigating their impact on occurrence and survival outcomes.

Background: Coeliac disease (CD) is common in patients with type 1 diabetes (T1D), but prevalence varies globally due to differing screening protocols. There have been substantial changes in screening guidelines over the past two decades.

Aim: To evaluate CD prevalence in patients with T1D, focusing on screening studies using antitissue transglutaminase (anti-tTG) antibody.

Article Synopsis
  • Synovial sarcoma is a rare type of cancer that usually grows in the lower part of the body, but this case involves a man with symptoms like shortness of breath and pain who had a lump in his wrist.
  • The man also had gynecomastia (breast tissue growth in men) and high levels of a hormone called βHCG, which indicated there was something unusual happening in his body.
  • The article wants to teach doctors that they should consider synovial sarcoma when they see certain symptoms or hormonal changes so they can catch it early and help avoid more serious problems.

Article Synopsis
  • Giant chorioangiomas are rare but can significantly threaten both fetal and maternal health, necessitating prompt and personalized treatment strategies to minimize risks.
  • This case report details a pregnant woman with multiple giant chorioangiomas leading to severe complications, including fetal anomalies and ultimately neonatal death shortly after birth.
  • Effective management of chorioangiomas involves careful monitoring through ultrasound and other assessments, with a focus on a coordinated approach among healthcare professionals to address the associated risks.

Article Synopsis
  • Wilms tumor (WT), typically rare in adults, forms just 3% of cases, with extrarenal Wilms tumor (ERWT) being even more uncommon, constituting 0.5-1% of WT cases; this document discusses a unique adult case of ERWT found in the spinal canal.
  • A 22-year-old woman experienced back pain that progressed to limb weakness and loss of bladder and bowel control, ultimately diagnosed through MRI and confirmed upon surgical removal of a spinal tumor.
  • The report highlights the rarity of ERWT in adults, suggesting a need for greater clinical awareness about atypical presentations, especially in patients with a history of spinal anomalies.

Introduction: Spinal epidermoid tumors are exceptionally rare, comprising less than 1 % of all spinal tumors. True intramedullary epidermoid cysts (IECs) are even more infrequent, constituting only 0.8 % of all spinal epidermoid tumors, with a notable cranial preference.

Introduction And Importance: Medulloblastoma in adults is a rare and highly aggressive central nervous system (CNS) tumor, representing less than 1 % of all brain tumors. Supratentorial metastasis is uncommon, and extra-neural metastasis occurs in approximately 5 % of cases, primarily in frontal and temporal lobes. Here, we present an exceptional case of parietal lobe metastasis in an adult with desmoplastic/nodular medulloblastoma.

Introduction And Importance: Schwannomas, originating from Schwann cells surrounding nerve sheaths, tend to be slow-growing. Among these, giant ancient schwannomas are remarkable for their rare occurrence and their capacity for substantial growth and regressive changes. Furthermore, the expansiveness and flexibility of the retroperitoneal space often conceal the symptoms of retroperitoneal schwannomas, leading to delayed diagnosis and allowing these tumors to grow significantly and become large and long-standing before detection.

Background: There are no comprehensive and accurate statistics on epidemiology and clinical features, especially during the COVID-19 period. The present study tries to describe the pediatric traumas in a referral treatment center in northern Iran during the COVID-19 period and to compare the available statistics with the years before pandemics to examine the differences in the epidemiology of this event in our country.

Methods: This cross-sectional study was performed on 543 children under 15 years admitted to this hospital due to different types of traumas in the first six months of 2019 (before the COVID-19 pandemic) and the first six months of 2020 (coinciding with the peak of the pandemic).

Background: Evidence suggests that referral cases of traumatic injuries have decreased during the COVID-19 pandemic both in childhood and in adulthood. Still we have very little evidence of referrals due to traumatic brain injury among children during the COVID-19 outbreak. The present study aimed to describe epidemiological and clinical features of pediatric traumatic brain injuries.
