Published: March 2025

Iron is the most common nutritional deficiency encountered in the United States, with over 15% of Americans using some form of daily oral iron supplementation. Although commonly associated with minor gastrointestinal side effects, severe gastrointestinal complications are rare. Direct cytotoxic mucosal damage and subsequent ulcer formation have rarely been reported. Among reported cases, most are found in the stomach with extragastric manifestations of siderosis being less commonly described. We report a rare case of esophageal siderosis related to oral iron supplementation.

Iron deficiency is a highly prevalent nutritional deficiency and the most common cause of anemia worldwide. Pregnant individuals are particularly susceptible due to increased demands to support expanding maternal blood volume and fetal growth. Iron deficiency and iron deficiency anemia are associated with maternal and neonatal morbidity, including preterm birth, preeclampsia, postpartum hemorrhage, and low birth weight.

Introduction: In UK hospitals, it is unclear how organisational structures are arranged to support effective implementation of peri-operative blood management practice strategies. The aim of this study was to conduct a national survey of organisations to describe local practices of peri-operative patient blood management and infrastructure availability in the UK.

Methods: A series of benchmarking standards was developed using recommendations informed by national standards, relevant literature and an expert panel.

Objective:  The aim of this study was to compare the effectiveness of various cleaning protocols on the bond strength of dual-cure resin cement following temporary cementation.

Materials And Methods:  Fifty-two human third molars were sectioned to expose superficial dentin and divided into four groups: (1) fresh, noncontaminated dentin (control); (2) pumice cleaning; (3) pumice + sodium bicarbonate air polishing; and (4) pumice + 10-methacryloyloxydecyl dihydrogen phosphate (MDP) based cleaner. Groups 2, 3, and 4 were treated with noneugenol zinc oxide temporary cement, followed by their respective cleaning protocols.

Ferric carboxymaltose (FCM) is widely used to correct anemia and replenish iron stores rapidly, particularly in Western populations. However, lower doses of FCM are typically used in East Asia, with limited research on their effectiveness, especially in postpartum women. This randomized controlled trial aimed to assess the efficacy of low-dose FCM compared with oral ferrous sulfate in increasing postpartum hemoglobin (Hb) levels and replenishing iron stores in East Asian women.
