Xanthogranulomatous cholecystitis (XGC) is a rare, chronic gallbladder inflammation often mistaken for gallbladder cancer (GBC) on imaging. Accurate differentiation is vital for appropriate treatment. This study aims to enhance computed tomography (CT) scan diagnostic accuracy for distinguishing XGC from GBC. ⋯ CT imaging can effectively differentiate XGC from GBC, and larger studies can further improve diagnostic accuracy.

Xenogeneic graft-versus-host disease (xGvHD) is an inevitable confounder of preclinical evaluation of adoptive immunotherapies on tumor-bearing immunodeficient mouse models. This study was designed to appraise the clinical and histopathological effects caused by xGvHD in severely immunodeficient mice considering the T cell dosage. ⋯ In preclinical evaluations, lower doses of T cell-based therapies are associated with milder xGvHD. Development of xGvHD may be averted by the use of CD4+T cell-depleted grafts. Histopathological and clinical scoring systems for evaluating xGvHD are significantly correlated. The lungs and liver are reliable organs for histopathological assessment and scoring of xGvHD.

Here, we report a case with concomitant variants: a novel homozygous HERC1 gene variant and a novel heterozygous PMP22 duplication. The 2-year-old male presented with seizures, developmental delay, macrocephaly, hypotonia, unilateral hypertrophy, thoracic scoliosis, normal brain MRI, and elevated homocysteine level which normalized after treatment. ⋯ The case underscores the challenges in understanding genotype-phenotype correlations and suggests a potential interplay between these genetic variants in shaping the current and future clinical phenotype of the patient. In the case of genetic diseases, this event may have important implications on family members' counseling, and concomitant variants in Charcot-Marie-Tooth (CMT) families should be considered when significant intra-familial clinical heterogeneity is observed.

We present a case with an intrathoracic caudate lobe in a 45-year-old woman who referred with a complaint of nonspecific chest pain. She denied previous history of trauma or surgery. ⋯ In the coronal plane, the mass was protruding to the abdomen and had similar density with liver. Magnetic resonance imaging confirmed the diagnosis.

Retinopathy of prematurity (ROP) is a significant cause of preventable premature infant vision loss. Many studies have reported different risk factors depending on the region. In this study, we evaluated the incidence of ROP and associated risk factors in a referral eye hospital in southeastern Iran. ⋯ Lower GA, lower BW, history of blood transfusion, and phototherapy were associated with ROP development. Phototherapy decreased the need for treatment among ROP patients.
