Background: Abdominoperineal resection (APR) is the standard treatment for locally advanced distal rectal cancer (LADRC) following neoadjuvant treatment when sphincter-preserving procedures are inapplicable. However, complications such as perineal site infection, perineal hernia and postoperative ileus remain ongoing challenges. We aimed to compare the rate of postoperative ileus due to pelvic incarceration in APR patients with/without pelvic inlet closure.

Purpose: To assess the impact of the The Controlling Nutritional Status (CONUT) score, an indicator of nutritional status, on the survival and prognosis after radical cystectomy.

Materials And Methods: The medical records of patients who underwent consecutive radical cystectomy operations with the diagnosis of muscle-invasive bladder cancer at our clinic were retrospectively examined. The patients were separated into two groups based on the cut-off CONUT score which was derived using the receiver operating characteristic (ROC) curve.

Background: There is a lot of research in terms of injuries and performance in football and nowadays aerobic capacity, spinal posture and mobility have been taken into consideration separately in terms of performance. Considering from a biomechanical perspective, we thought spinal curvature and mobility may affect aerobic performance and investigated the relationship between them.

Research Question: Do young soccer players' segmental spinal curvature and mobility affect their aerobic capacity and maximal exercise performance?

Methods: Thirty-four young league players (mean age 16.

: Metabolic dysfunction-associated steatotic liver disease (MASLD) and polycystic ovary syndrome (PCOS) share several pathophysiological mechanisms. While the prevalence of MASLD has been extensively studied in PCOS populations, the occurrence of PCOS among female adolescents with transient elastography (TE)-confirmed MASLD in pediatric hepatology settings remains poorly characterized. This cross-sectional study aims to address this knowledge gap and elucidate potential clinical and biochemical differences between female adolescents with MASLD and comorbid PCOS compared to those without PCOS.

Article Synopsis
  • The study evaluated five different scoring systems (FGSI, UFGSI, ACCI, qSOFA, LRINEC) to predict outcomes in patients with Fournier gangrene, analyzing data from 311 patients between 2010 and 2024.
  • Univariate and multivariate analyses showed that UFGSI and FGSI were the most effective scoring systems in predicting mortality, with higher values seen in non-survivor patients.
  • ROC analysis determined optimal cut-off values for each scoring system, with UFGSI proving to be the most accurate for predicting mortality, achieving 84% sensitivity and 97% specificity at a score ≥12.

Article Synopsis
  • Enzyme replacement therapy (ERT) can effectively manage lysosomal storage diseases, but it may cause hypersensitivity reactions in some patients.
  • A study reviewed medical records of pediatric patients to assess the frequency and characteristics of these allergic reactions, finding that 25.3% experienced them, with anaphylaxis occurring in 6 cases.
  • Management of hypersensitivity may include premedication and slower infusions, and some patients may require desensitization protocols to continue ERT safely.

Aim: The aim of this study was to compare the differences between angles of bladder neck in girls with overactive bladder and those in healthy ones using transabdominal ultrasonography.

Materials And Methods: This study consists of 28 girls complicated with overactive bladder (Group I) and 40 healthy girls (Group II). The anteroposterior vesical wall angle (APVA), urethroposterior vesical wall angle (UPVA), urethroanterior vesical wall angle (UAVA), thickness of bladder mucosa, distance of urethral orifices, and distance between ureter and urethra orifice were measured in supine position using transabdominal ultrasonography.

Circadian rhythms synchronize all biological functions, enabling humans to foresee and respond better to periodic environmental changes. The coronavirus disease (COVID-19) lockdown regulations significantly changed the lighting conditions in pregnant women, leading to chronological disruption. This study aimed to investigate the impact of the COVID-19 on the circadian rhythm of cesarean deliveries.

The cardinal phenotypic hallmarks of Marfan syndrome (MFS) include cardiac, ocular, and skeletal abnormalities. Since the clinical phenotype of MFS is highly heterogeneous, with certain symptoms appearing as children age, the diagnostic process and establishing a genotype-phenotype association in childhood MFS can be challenging. The lack of sufficient childhood studies also makes it difficult to interpret the subject.

Purpose: Studies examining prediction of complete response (CR) in locally advanced rectum cancer (LARC) from pre/post chemoradiotherapy (CRT) magnetic resonance imaging (MRI) are performed mostly with segmentations of the tumor, whereas only in two studies segmentation included tumor and mesorectum. Additionally, pelvic extramesorectal region, which is included in the clinical target volume (CTV) of radiotherapy, may contain information. Therefore, we aimed to compare predictive rates of radiomics analysis with features extracted from segmentations of tumor, tumor+mesorectum, and CTV.

Objective: Maturity onset diabetes of the young (MODY) occurs due to mutations in genes involved in pancreatic beta cell function and insulin secretion, has heterogeneous clinical and laboratory features, and account for 1-5% of all diabetes cases. The prevalence and distribution of MODY subtypes vary between countries. The aim of this study was to evaluate the clinical and laboratory characteristics, mutation distribution, and phenotype-genotype relationship in a large case series of pediatric Turkish patients genetically diagnosed with MODY.

Introduction: Parallel to the worldwide increase in obesity, the epidemic of chronic liver disease is increasing also in pediatric population. Our aim is to provide a different outlook on the current screening confusion in pediatric non-alcoholic fatty liver disease (NAFLD) with the non-invasive vibration-controlled transient elastography (VCTE) method.

Materials And Methods: This single-center, cross-sectional, comparative study was performed at the tertiary center, included 95 patients with obesity and 116 controls, both groups were 9-18 years of ages.

The stone density (SD) is not the same in all parts of the stone due to the heterogeneous nature of the stone and the shock wave (SW) passes through tissues of many different densities until it reaches the stone. These factors affect the success of Extracorporeal Shock Wave Lithotripsy (ESWL). We aimed to evaluate the effect of the Variation Coefficient of Stone Density (VCSD) and Renal Cortical Tickness (RCT) on the success of ESWL.
