Background: Thalassemia is a genetic disorder of hemoglobin synthesis, which requires regular blood transfusion therapy leading to iron overload in the body tissues. Transfusional hemosiderosis is a major cause of morbidity and mortality in these patients. Reliable methods for evaluation of iron overload are either invasive, costly or remotely available. Therefore, a simple technique of monitoring iron overload is desirable.
Aim: To know whether iron can be demonstrated in exfoliated buccal cells of β-thalassemia major patients using Perls' Prussian blue method and to correlate it with serum ferritin levels.
Materials And Methods: Smears were obtained from buccal mucosa of 60 randomly selected β-thalassemia major patients and 30 healthy subjects as controls. Smears were stained with Perls' Prussian blue method. Blood samples were taken for estimation of serum ferritin levels.
Statistical Analysis: Chi-square, Mann-Whitney, and Spearman Rank's Correlation tests.
Results: Perls' positivity was observed in 71.7% of thalassemic patients with a moderately positive correlation to serum ferritin levels.
Conclusion: Oral exfoliative cytology can be a useful tool in demonstration of iron overload in thalassemic patients, however, further research in this field in the direction of quantification of these procedures is required, which can establish this non-invasive procedure as an ideal screening tool.

Intravascular hemolysis releases hemoglobin (Hb) from red blood cells under specific conditions, yet the effect of hemolysis in aquaculture systems remain poorly understood. In this study, a continuous hemolysis model for grass carp was established by injection of phenylhydrazine (PHZ) to investigate the mechanistic impacts of sustained hemolysis. PHZ-induced hemolysis altered liver color, and subsequent hematoxylin and eosin staining revealed substantial Hb accumulation in the head kidney, accompanied by inflammatory cell infiltration and vacuolization in liver tissue.

Background: Autoimmune hemolytic anemia (AIHA) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) is often refractory and relapsing, leading to increased mortality post-HSCT.
Methods: We retrospectively analyzed the cases of patients with transfusion-dependent β-thalassemia (TDT) who underwent allo-HSCT to study their clinical features, the occurrence of AIHA post-HSCT, and treatment response and to explore the possible pathogenesis of AIHA.
Result: A total of 113 patients were registered in the study, out of whom 14 developed AIHA following allo-HSCT, resulting in a cumulative incidence of 12.

Background: Our studies suggest that iron-overloaded rats developed neurotoxicity and cognitive impairment (1,2). An increase in brain mitochondrial fission and brain mitophagy have been considered as one of underlying mechanisms in brain with iron-overloaded condition (3,4). Hence, a pharmacological intervention focused on preventing brain mitochondrial pathologies is required.

Background: UK Biobank data show mutations related to the iron disorder hemochromatosis can approximately double the risk of dementia, in particular clinically diagnosed vascular dementia. Insights into the etiology of this dementia may be provided by cerebrovasculopathy in our new "Aβ+Iron" mouse model, which combines hemochromatosis-related mutations and amyloidosis, with increases in soluble Aβ species and plaques. This was created by crossing an established APP/PS1 model of β-amyloidosis with our reported HfexTfr2 model of hemochromatosis-related mutations exhibiting brain iron dyshomeostasis (Heidari Mol.

Importance: Hemochromatosis is rare in domestic animals, and iron-induced myopathy has not been reported in veterinary medicine. This case is the first report of iron-overload myopathy owing to hemochromatosis in a dog.
Case Presentation: A 9-year-old spayed female Donggyeong dog presented with severe forelimb lameness.
