Abstract
Background Peripheral neuropathy is a controversial but serious complication of beta-thalassemia (β-Th). Although few studies have reported no relationship between neuropathy and thalassemia, many have linked it with increasing age, iron overload, and iron chelator toxicity. This study aims to investigate the presence of neuropathy in β-Th using corneal nerve fibers. Methodology A cross-sectional study was conducted using corneal confocal microscopy on individuals with intermediate and major β-Th who were compared to healthy individuals. The main outcome variables were corneal main nerve and branch nerve densities which were calculated using Image J software. The comparison between groups was done using the independent-samples F-test and Bonferroni post-hoc analysis. Results There was reduced corneal main nerve and branch nerve density in β-Th intermediate and major patients compared to the control group, and the results were statistically significant (p-value <0.05). However, a significant correlation was not observed between serum ferritin levels and corneal nerve parameters. Conclusions The reduction in corneal nerve parameters in β-Th patients compared to healthy controls can be an indication of peripheral neuropathy in β-Th. Further work is needed to confirm these findings.

Abstract
Red blood cell (RBC) transfusion is one of the most common therapeutic procedures in modern medicine. Although frequently lifesaving, it often has deleterious side effects. RBC quality is one of the critical factors for transfusion efficacy and safety. The role of various factors in the cells’ ability to maintain their functionality during storage is widely discussed in professional literature. Thus, the extra- and intracellular factors inducing an accelerated RBC aging need to be identified and therapeutically modified. Despite the extensively studied in vivo effect of chronic hyperglycemia on RBC hemodynamic and metabolic properties, as well as on their lifespan, only limited attention has been directed at the high sugar concentration in RBCs storage media, a possible cause of damage to red blood cells. This mini-review aims to compare the biophysical and biochemical changes observed in the red blood cells during cold storage and in patients with non-insulin-dependent diabetes mellitus (NIDDM). Given the well-described corresponding RBC alterations in NIDDM and during cold storage, we may regard the stored (especially long-stored) RBCs as “quasi-diabetic”. Keeping in mind that these RBC modifications may be crucial for the initial steps of microvascular pathogenesis, suitable preventive care for the transfused patients should be considered. We hope that our hypothesis will stimulate targeted experimental research to establish a relationship between a high sugar concentration in a storage medium and a deterioration in cells’ functional properties during storage.

Abstract
Intracranial hemorrhage (ICH) is rarely seen in patients with thalassemia. A seven-year-old male, known case of beta-thalassemia major, on irregular packed cell transfusions (elsewhere) and non-compliant with chelation therapy, presented with congestive cardiac failure (Hb-3 gm/dl). He received three packed red cell transfusions over 7 days (cumulative volume 40 cc/kg). On the 9th day, he developed projectile vomiting and two episodes of generalized tonic-clonic convulsions with altered sensorium. He had exaggerated deep tendon reflexes and extensor plantars. CT-scan of brain revealed bilateral acute frontal hematoma with diffuse subarachnoid hemorrhage (frontal and parietal). Coagulation profile was normal. CT-angiography of brain showed diffuse focal areas of reduced caliber of anterior cerebral, middle cerebral, and basilar and internal carotid arteries (likely to be a spasmodic reaction to subarachnoid hemorrhage). He required mechanical ventilation for 4 days and conservative management for the hemorrhage. However, on the 18th day, he developed one episode of generalized tonic-clonic convulsion and his sensorium deteriorated further (without any new ICH) and required repeat mechanical ventilation for 12 days. On the 28th day, he was noticed to have quadriplegia (while on a ventilator). Nerve conduction study (42nd day) revealed severe motor axonal neuropathy (suggesting critical illness polyneuropathy). He improved with physiotherapy and could sit upright and speak sentences at discharge (59th day). The child recovered completely after 3 months. It is wise not to transfuse more than 20 cc/kg of packed red cell volume during each admission and not more than once in a week (exception being congestive cardiac failure) for thalassemia patients.

Abstract
Thalassemia is characterized by a defect in the synthesis of one or more of the globin subunits of hemoglobin. This defect results in imbalance in the α/β-globin chain ratio, ineffective erythropoiesis, chronic hemolytic anemia, and iron overload. With advances in diagnosis, treatment, and transfusion support, the prognosis of patients with thalassemia has improved over the past few decades. An increasing number of patients with thalassemia is living with long-term complications, including cardiomyopathy, chronic liver disease, endocrinopathy, and infections. In this paper, we review common complications that bring the patient with thalassemia to urgent or emergent medical attention. We also discuss the aspects of emergency care that are most relevant while caring for the patient with thalassemia in the emergency department.
