Impact of Graft Size Matching on the Early Post-Transplant Complications and Patients Survival in Children after Living Donor Liver Transplantations.

We aimed to assess the impact of the graft-recipient weight ratio (GRWR) on early post-transplant complications and patient survival rates in children after living donor liver transplantation (LDLT). We retrospectively analyzed 321 patients who underwent LDLT from 2004 to 2019. The recipients were categorized into four groups: 37 patients had a GRWR ≤ 1.

Factors associated with loneliness in patients with diabetes mellitus.

Aim: To (a) explore the prevalence of loneliness in patients with diabetes mellitus and (b) identify loneliness-related factors in the group of hospitalized patients with diabetes mellitus.

Design: A cross-sectional study.

Methods: The study included 248 patients with diabetes mellitus who were staying in six Polish hospitals.

ATP6AP1-CDG: Follow-up and female phenotype.

In 2016, 11 male patients were reported with immunodeficiency and hepatic, gastric and (in some) neurological disease due to X-linked ATP6AP1 deficiency (ATP6AP1-CDG). In 2018, three other patients were reported with additional features: connective tissue abnormalities, sensorineural hearing loss, hyperopia, glomerular and tubular dysfunction, exocrine pancreatic insufficiency and altered amino acid and lipid metabolism. We here present a follow-up of three reported siblings showing progression of deafness to total hearing loss, progressive loss of hair up to alopecia, chestnut skin and, at last follow-up, in some of them proteinuria.

NGLY1 deficiency: Novel patient, review of the literature and diagnostic algorithm.

Objectives: Together with the lysosomal storage diseases, NGLY1 deficiency is a congenital disorder of deglycosylation (NGLY1-CDDG). Since the first report in 2012, 26 patients have been described. All but one were diagnosed by exome or genome sequencing; the remaining one was identified by finding an increased concentration of an urinary marker.

Leigh syndrome caused by mutations in is associated with a better prognosis.

Objectives: Mitochondrial methionyl-tRNA formyltransferase (MTFMT) is required for the initiation of translation and elongation of mitochondrial protein synthesis Pathogenic variants in have been associated with Leigh syndrome (LS) and mitochondrial multiple respiratory chain deficiencies. We sought to elucidate the spectrum of clinical, neuroradiological and molecular genetic findings of patients with bi-allelic pathogenic variants in .

Methods: Retrospective cohort study combining new cases and previously published cases.

Virginal breast hypertrophy in a patient with Beckwith-Wiedemann syndrome.

Virginal breast hypertrophy is a multidisciplinary condition including surgical, pediatric, and endocrine/gynecological disciplines, and its successful diagnosis and management requires complex, team approach.

Ten new ATM alterations in Polish patients with ataxia-telangiectasia.

Inherited biallelic mutations of the ATM gene are responsible for the development of ataxia telangiectasia (AT). The objective of the present study was to conduct molecular analysis of the ATM gene in a cohort of 24 Polish patients with ataxia-telangiectasia with aim being to provide an updated mutational spectrum in Polish AT patients. As a result of molecular analysis, the status of recurrent mutation was confirmed and ten new ATM variants were detected.

Serum very-long-chain fatty acids levels determined by gas chromatography in the diagnosis of peroxisomal disorders in Poland.

Peroxisomal disorders are a large group of genetically determined metabolic diseases in which the biogenesis of peroxisomes is defective or there is a deficiency of only a single enzyme activity or substrate transporter. The objective of this report is to present ten years of experience in the diagnostics of peroxisomal disorders in Poland. Very-long-chain fatty acid (VLCFA) levels as a biomarker for peroxisomal defects were determined by gas chromatography in 1264 subjects with suspicion of peroxisome disease.
