Chanarin-Dorfman syndrome is an autosomal recessive lipid storage disease characterized by non-bullous congenital ichthyosiform erythroderma, and involvement of the liver, muscles and central nervous system due to a multisystemic accumulation of neutral lipids in various types of cells. Less than 100 affected individuals have been reported worldwide, the majority from the Mediterranean and Middle-East countries, especially Turkey. We present clinical and molecular data of four affected relatives with Chanarin-Dorfman syndrome homozygous for a N209X mutation in ABHD5, and provide a short review by comparing patients with N209X homozygous mutations to patients with other ABHD5 mutations. No major clinical differences exist between individuals with an N209X mutation and those with other mutations, which argues against a genotype/phenotype correlation.

Chanarin-Dorfman syndrome (CDS) is a multisystem autosomal recessive disorder due to variants of the ABHD5 gene, characterized by lipid vacuoles in the liver and leukocytes, and possible involvement of eyes, ears, skeletal muscle, and central nervous system. CDS may present with skin changes, most commonly congenital non- bullous ichthyosiform erythroderma, however erythrokeratoderma-like findings have been rarely reported in CDS patients. Herein, we report clinical, histopathological and genetic findings of four patients with CDS presenting with different clinical forms of erythrokeratoderma (three with progressive symmetric erythrokeratoderma-like features and one with erythrokeratoderma variabilis (EKV)-like features), including one patient with a novel mutation in ABHD5.

Background: Drug-related problems (DRPs) and potentially inappropriate prescribing (PIP) are associated with adverse patient and health care outcomes. In the setting of hospitalized older patients, Clinical Decision Support Systems (CDSSs) could reduce PIP and therefore improve clinical outcomes. However, prior research showed a low proportion of adherence to CDSS recommendations by clinicians with possible explanatory factors such as little clinical relevance and alert fatigue.

Background: Multiple Acyl-CoA Dehydrogenase Deficiency (MADD), also known as Glutaric Aciduria Type II, is an exceptionally rare autosomal recessive genetic disorder that disrupts the metabolism of fatty acids, amino acids, and choline. It presents with a wide range of clinical manifestations, from severe neonatal-onset forms to milder late-onset cases, with symptoms including metabolic disturbances and muscle weakness. Jordan's anomaly is a distinctive morphological feature found in peripheral blood white cells and is typically associated with Neutral Lipid Storage Disease (NLSD).

The aim of this study was to explore the association between differential percentages of dendritic cell (DC) subsets in peripheral blood and malignancy (grade and lymph node metastasis) of peritoneal adenocarcinoma patients and the frequencies of dendritic cell subsets in the normal controls. The peripheral blood of 30 patients with peritoneal adenocarcinoma and 12 healthy controls were collected for multicolor flow cytometry analysis. Peritoneal adenocarcinoma patients were grouped according to the malignant degree (grade and lymph node metastasis).
