This paper discusses a case study of a 19-year-old male student who engaged in daily long distance running and presented with complaints of fatigue and dizziness. Laboratory test revealed a hemoglobin of 7.7 g/dl and a bone marrow negative for iron. After a complete evaluation no source of blood loss was identified. His iron deficient state may be caused by his exposure to long distance running for some years. Recent work from Sweden reports iron deficiency in eight runners, demonstrated by bone marrow examination. Further work in West Germany shows low ferritin values in runners. Source of iron loss may be from hemoglobinuria and/or excessive sweating. Hemoglobin and ferritin values should be monitored in runners every six to 12 months.

Centipede bites are usually characterized by mildly to moderately painful encounters with humans, however, they are relatively infrequent. The vast majority of centipede envenomations do not cause severe symptoms and only in very rare cases more serious symptoms such as myocardial ischemia and infarction, hematuria, hemoglobinuria, rhabdomyolysis, hemorrhage, pruritus, eosinophilic cellulitis, as well as anaphylaxis are observed. More prevalent are symptoms including pain, paresthesia, lethargy, localized necrosis, headache, dizziness and nausea. The numerous symptoms and complications elicited by these envenomations indicate that centipede venom possesses an arsenal of chemical components with functional diversity. Centipede venom is a rich and complex natural source of bioactive proteins, peptides and other small molecules that aid in predation or defense. The venom can induce myotoxic, cardiotoxic, neurotoxic and other toxic effects. The constituents target different cellular processes and pathways which in turn trigger a cascade of physiological reactions in the victim. The venom components are potent and selective on peripheral targets; thus, they are valuable in studying the molecular basis of these envenomation symptoms and complications. This review highlights the clinical importance of centipede envenomation and the recent discoveries on the underlying molecular mechanisms of the resulting symptoms which is crucial in therapy.
