It is a hoofed mammal. It has thick, hairless skin, short legs and a large head with an enormous mouth.The hippopotamus is found in and near lakes and rivers in tropical Africa . The Africans call it 'River Horse'. It swims about with its whole body under water, but it keeps its eyes and nostrils above the water at all times. It does this to breathe and look around while it is swimming.展开更多

He was found to have a significantly elevated L-lactate dehydrogenaseand an elevated plasma free hemoglobin consistent with intravascular hemolysis.After the hemolysis ceased,both the black urine and dysphagia resolved spontaneously.Transient esophageal dysfunction,as a manifestation of gastrointestinal dysmotility,is known to occur in the setting of hemolysis.Paroxysmal nocturnal hemoglobinuria is another recognized cause of massive hemolysis with gastrointestinal dysmotility occurring in25%-35%of patients during a paroxysm.Intravascular hemolysis increases plasma free hemoglobin,which scavenges nitric oxide(NO),an important second messenger for smooth muscle cell relaxation.The decrease in NO can lead to esophageal spasm and resultant dysphagia.In our patient the resolution of hemolysis resulted in resolution of dysphagia.展开更多
