Published: November 2001

We summarize the diagnosis, outcome, and molecular studies of five Mediterranean patients with citrullinemia: four neonatal classical forms and one subacute form, who also suffers from Down syndrome and presented with severe hepatic encephalopathy at age 7. Mutational analysis revealed three alleles with a common mutation and five new mutations: two Moroccan siblings are homozygous for G390R, the subacute form is compound heterozygous for G390R/G117D (new mutation), and the two other neonatal forms are compound heterozygous for four new mutations: V69A/E270Q and T119I(R108L)/?.

Purpose: To determine whether there is a difference in apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values in white matter pathways in the subacute period after COVID-19 infection and to evaluate the correlation between diffusion tensor imaging (DTI) metrics and laboratory findings.

Material And Methods: The study included 64 healthy controls and 91 patients. Patients were classified as group 1 (all patients, n = 91), group 2 (outpatients, n = 58), or group 3 (inpatients, n = 33).

Necrotizing fasciitis (NF) is a life-threatening disease that is diagnosed through an exploratory incision and typically requires surgical debridement. Reports of non-surgical cures are limited to specific cases, such as NF affecting only the head and neck regions. The two patients (a woman and a man) were both in their 70s and underwent maintenance dialysis for diabetic nephropathy.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder characterized by widespread immune dysregulation that affects multiple organ systems, including the skin and cardiovascular system. The crosstalk between different cell death pathways-such as apoptosis, necroptosis, and neutrophil extracellular trap (NETosis), plays a pivotal role in the pathogenesis of SLE, influencing both cutaneous and cardiac manifestations. Cutaneous lupus erythematosus (CLE) is one of the most common early signs of SLE, affecting up to 80% of patients.
