Introduction: Dysmenorrhea is a painful symptom associated with uterine contractions and menstrual bleeding and is treated by administering analgesic drugs. Since progesterone receptors (PRs) have a major role in regulating uterine tissues (myometrium and endometrium) oral contraceptives are used off-label for treating primary or secondary dysmenorrhea. The development of selective progesterone receptor modulators (SPRMs) a class of synthetic steroids with agonistic, antagonistic, or mixed effects in targeting PRs in different tissues stimulated their possible clinical use for treating secondary dysmenorrhea related to uterine diseases (endometriosis, adenomyosis, uterine fibroids).

Objective: Chronic non-bacterial osteomyelitis (CNO) is a rare autoinflammatory bone disease associated with other chronic inflammatory diseases such as familial Mediterranean fever (FMF), juvenile idiopathic arthritis (JIA), spondylarthropathies, inflammatory bowel disease (IBD), and pyoderma gangrenosum. We aimed to describe the clinical and follow-up characteristics of patients with CNO and to compare findings between patients with and without comorbidities.

Methods: The clinical records of patients with CNO who were followed up in our pediatric rheumatology clinic between 2018 and 2023 were reviewed.

Background: Griscelli syndrome (GS) is a rare genetic disorder characterized by oculocutaneous albinism and variable immune dysfunction. Among three distinct types of GS, occurring due to different genetic mutations; GS type 1 presents with neurological manifestations, hemophagocytic lymphohistiocytosis (HLH) generally develops in GS type 2, and GS type 3 primarily exhibits oculocutaneous albinism. HLH, a life-threatening condition with excessive immune activation, may occur secondary to various triggers, including infections, and develop in different tissues, as well as in the testis, similar to Erdheim-Chester disease.

Background: The management of pediatric acute myeloid leukemia (AML) is based on the prognostic risk classification of initial leukemia. Targeted next-generation sequencing (NGS) is a reliable method used to identify recurrently mutated genes of pediatric AML and associated prognosis.

Methods: In this study, we retrospectively evaluated the prognostic, and therapeutic utility of a targeted NGS panel covering twenty-five genes, in 21 children with de novo and 8 with relapsed or secondary AML.

Background: Bronchopulmonary dysplasia (BPD) is a chronic lung disease in premature infants caused by an imbalance between lung injury and lung repair in the developing immature lungs of the newborn. Pulmonary inflammation is an important feature in the pathogenesis of BPD. The aim of this study was to evaluate the relationship between the inflammatory microenvironment and the levels of visfatin and nesfatin-1, which are among the new adipocytokines, in BPD patients.

Background: Metoclopramide, a dopamine antagonist employed for its antiemetic effects, can precipitate neuropsychiatric adverse effects, including extrapyramidal symptoms and, in a few instances, acute psychosis. Although there have been reports of metoclopramide-induced psychosis in elderly individuals, there is no documentation of such incidents in children as far as we are aware.

Case Presentation: This case report describes an 11-year-old girl with a history of mild intellectual disability and attention deficit hyperactivity disorder, managed with 10 mg of methylphenidate daily.

Fournier gangrene is a rare but severe complication of ulcerative colitis, characterized by necrotizing fasciitis affecting the genital and perineal regions. We present a case of a 53-year-old man with a history of ulcerative colitis and cytomegalovirus (CMV) colitis who developed Fournier gangrene, an exceptionally uncommon occurrence in this patient population. The patient initially presented with intense pain, swelling, and skin discoloration in the genital area, accompanied by systemic symptoms, including fever.

Zerumbone is a sesquiterpene phytochemical with cytotoxic activity against cancer. This study aimed to evaluate the effect of zerumbone on cell viability by WST-1 test, apoptosis by TUNEL, lipid peroxidation markers (malondialdehyde, MDA, and 4-hydroxynonenal, HNE) by using assay kits, and biomolecular changes by ATR-FTIR spectroscopy in A549 cells. After zerumbone (0-100 μM) incubation for 24, 48, and 72 h, the number of TUNEL-positive cells was found to be higher in zerumbone-treated cells than in controls, in consistent with cell morphology results.

NMDAR antagonists, such as memantine and ketamine, have shown efficacy in treating neurodegenerative diseases and major depression. The mechanism by which these drugs correct the aforementioned diseases is still unknown. Our study reveals that these antagonists significantly enhance 20S proteasome activity, crucial for degrading intrinsically disordered, oxidatively damaged, or misfolded proteins, factors pivotal in neurodegenerative diseases like Alzheimer's and Parkinson's.
