An esophageal food bolus obstruction is a medical emergency caused by the obstruction of the esophagus by an ingested foreign body.. It is usually associated with diseases that may narrow the lumen of the esophagus, such as eosinophilic esophagitis, Schatzki rings, peptic strictures, webs, or cancers of the esophagus; rarely it can be seen in disorders of the movement of the esophagus, such as ...
Endoscopic foreign body retrieval is the first-line treatment for removal of a foreign body from the alimentary tract. [ 10 ] Glucagon has been used to treat esophageal foreign bodies, with the intent that it relaxes the smooth muscle of the lower esophageal spincter to allow the foreign body to pass into the stomach.

Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
The ideal is to increase the body's iron deposits, measured as levels of ferritin in serum, with the aim of reaching a ferritin value between 30 and 100 ng/mL. A clinical study has shown an increase in ferritin levels in those taking iron compared with others receiving a placebo . [ 11 ]
Cameron lesions are usually found in older adults with anemia symptoms such as fatigue, shortness of breath, and appearing pale. Blood tests in iron deficiency show low hemoglobin, microcytic hypochromic red cells, and low iron-binding saturation and ferritin levels. The lesions are visualized by esophagogastroduodenoscopy.
Iron-deficiency anemia is confirmed by tests that include serum ferritin, serum iron level, serum transferrin, and total iron binding capacity. [59] A low serum ferritin is most commonly found. However, serum ferritin can be elevated by any type of chronic inflammation and thus is not consistently decreased in iron-deficiency anemia. [23]
Iron can be stored in ferritin as ferric iron due to the ferroxidase activity of the ferritin heavy chain. [28] Dysfunctional ferritin may accumulate as hemosiderin, which can be problematic in cases of iron overload. [29] The ferritin storage iron pool is much larger than the labile iron pool, ranging in concentration from 0.7 mM to 3.6 mM. [25]
Haemochromatosis is protean in its manifestations, i.e., often presenting with signs or symptoms suggestive of other diagnoses that affect specific organ systems.Many of the signs and symptoms below are uncommon, and most patients with the hereditary form of haemochromatosis do not show any overt signs of disease nor do they have premature morbidity, if they are diagnosed early, but, more ...
