Pediatric siMS score: A new, simple and accurate continuous metabolic syndrome score for everyday use in pediatrics

Background: The dichotomous nature of the current definition of metabolic syndrome (MS) in youth results in loss of information. On the other hand, the calculation of continuous MS scores using standardized residuals in linear regression (Z scores) or factor scores of principal component analysis (PCA) is highly impractical for clinical use. Recently, a novel, easily calculated continuous MS score called siMS score was developed based on the IDF MS criteria for the adult population. Objective: To develop a Pediatric siMS score (PsiMS), a modified continuous MS score for use in the obese youth, based on the original siMS score, while keeping the score as simple as possible and retaining high correlation with more complex scores. Subjects and methods The database consisted of clinical data on 153 obese (BMI ≥95th percentile) children and adolescents. Continuous MS scores were calculated using Z scores and PCA, as well as the original siMS score. Four variants of PsiMS score were developed in accordance with IDF criteria for MS in youth and correlation of these scores with PCA and Z score derived MS continuous scores was assessed. Results: PsiMS score calculated using formula: (2xWaist/Height) + (Glucose(mmol/l)/5.6) + (triglycerides(mmol/l)/1.7) + (Systolic BP/130)—(HDL(mmol/l)/1.02) showed the highest correlation with most of the complex continuous scores (0.792–0.901). The original siMS score also showed high correlation with continuous MS scores. Conclusion: PsiMS score represents a practical and accurate score for the evaluation of MS in the obese youth. The original siMS score should be used when evaluating large cohorts consisting of both adults and children

Isolated Splenic Metastasis of Primary Lung Cancer Presented as Metachronous Oligometastatic Disease—A Case Report

Modern oncology practice and new antitumor drugs prolonged disease-free intervals in patients with lung cancer. Patients with distant metastatic disease are treated only with palliative intent. The International Association for the Study of Lung Cancer, in the 8th edition of the TNM classification, for the first time includes oligometastatic disease as a clinical state that describes the patients with distant metastasis, limited in number and organ sites, who may have more indolent biology. In this paper, we present a case of a 56-year-old man who was admitted to our clinic regarding a radiologically diagnosed splenic lesion of uncertain nature, and who underwent a left upper lobectomy for primary lung cancer 12 years before. After a detailed radiological diagnosis, it was concluded that it is highly suspected metastatic lesion of the spleen and the patient underwent a splenectomy. While no definitive protocols exist on the management of isolated splenic metastasis from lung cancer, splenectomy, in suitable patients, with reasonable survival expectations, improves patient disease-free survival and can prevent potentially life-threatening complications, such as splenic rupture. 18F-FDG PET has very high sensitivity and specificity for differentiating benign and malignant splenic lesions especially in patients who are in the follow up protocol due to primary malignancy

Total Pancreatectomy for Multicentric Cystic Neuroendocrine Tumor of the Pancreas: A Case Report

Pancreatic neuroendocrine tumors (PNETs) are uncommon pancreatic neoplasms with malignant potential, heterogeneous clinical behavior, as well as imaging appearance. These tumors represent less than 3% of all pancreatic neoplasms with typical CT presentation as solid, well-circumscribed, hypervascular lesions. Cystic PNET is a rare pancreatic tumor which is nowadays more often detected due to the widespread use of high-resolution cross-sectional imaging. They are mainly solitary lesions most commonly localized in the body and the tail of the pancreas. Due to cystic presentation these lesions often present a diagnostic challenge to both experienced radiologists and pathologists. Herein, we present a rare case of synchronous, multiple cystic and solid pancreatic neuroendocrine tumors, which due to their extensiveness required total dudenopancreatectomy with splenectomy. Histopathological findings confirmed microscopic and macroscopic cystic components as well as typical solid variants of neuroendocrine tumors along the entire pancreas

“Bezoar Egg”—A Rare Cause of Small Bowel Obstruction

Small bowel obstruction is a frequent medical condition with various causes, the most common being postoperative adhesions, volvulus, intussusception, hernias, and tumors. A bezoar-induced blockage of the small intestine is a rare condition that accounts for approximately 4% of all small bowel obstruction cases. Herein, we present the case report of a 71-year-old patient with diffuse abdominal pain caused by a small bowel obstruction due to a calcified bezoar (bezoar egg) resulting from a post-radiation intestinal stricture. The patient underwent a small bowel excision with the extraction of the bezoar, after which a full recovery was made
