BACKGROUND
Methemoglobinemia results from oxidation of ferrous to ferric iron in hemoglobin. In addition to a functional anemia, methhemoglobinemia causes the O2-binding affinity of the remaining O2 sites in the hemoglobin tetramer to increase; essentially shifting the oxyhemoglobin dissociation
This basic review is intended to summarize the current knowledge of methemoglobinemia as an important cause of secondary headache with the hope of generating a growing interest in studying this phenomenon.We describe the pathological underpinnings of METHODS
A 85-year-old patient, initially treated for aspiration pneumonia on the intensive care unit acutely complained again of nausea which was immediately treated by an i. v. bolus of metoclopramide (MCP). Without another incident of aspiration she subsequently developed acutely massive dyspnoea,
Methemoglobinemia among infants is a rare and potentially fatal condition caused by genetic enzyme deficiencies, metabolic acidosis, and exposure to certain drugs and chemicals. The most widely recognized environmental cause of this problem is ingestion of nitrate-containing water. Ingestion of
OBJECTIVE
To report a case of acute methemoglobinemia in a patient treated with celecoxib for osteoarthritis.
METHODS
A 72-year-old African American man developed an acute confusional state (ACS) one month after receiving celecoxib for osteoarthritis of his knee joints. There was no other
There is a long list of prescribed and over the counter oxidizing agents that can induce methemoglobinemia. We report a case of methemoglobinemia in a 46-year-old man with a mayor depression disorder who ingested 30 pills of diphenhydramine, 30 pills of haloperidol, 20 pills of dolagesic, 20 pills
BACKGROUND
This case conference reviews laboratory methods for assessing oxygenation status: arterial blood gases, pulse oximetry, and CO-oximetry. Caveats of these measurements are discussed in the context of two methemoglobinemia cases.
METHODS
Case 1 is a woman who presented with increased
Introduction: Over the past decade, Miracle Mineral Solution (sodium chlorite) has been promoted as a cure-all for many conditions.
Case report: A 9-year-old boy presented with
The herbicide pendimethalin (STOMP) shares a similar chemical structure with nitro compounds such as dinitrobenzene, which was previously demonstrated to cause methemoglobinemia in mammals. However, reports on STOMP poisoning in humans are rare. We reviewed 71 STOMP poisoning cases (42 men and 29
A 19-year old woman ingested an unknown amount of sodium azide (NaN3). The earliest symptoms were nausea and loss of vision. Within a few hours her clinical features were dominated by central nervous system signs, acute pulmonary edema, lactic acidosis, and hypothermia. The patient died within 12
A case of acute Dapsone intoxication due to voluntary ingestion of 3 g of this drug as a suicide attempt is described. A severe methemoglobinemia developed, accompanied by intense cyanosis, dyspnea, headache, and nausea. Subsequently, significant sulfhemoglobinemia responsible for prolonged cyanosis
On rare occasions benzocaine has produced methemoglobinemia from oral, rectal and dermal exposures. There is disagreement whether this is an idiosyncratic event or a dose-related event. To gain a better perspective on this problem we retrospectively reviewed cases at 4 large regional poison centers
BACKGROUND
Antimicrobial drugs that can be taken orally are needed for the treatment of Pneumocystis carinii pneumonia in patients with the acquired immunodeficiency syndrome (AIDS). Preliminary data indicate that dapsone with trimethoprim may be an effective alternative to
BACKGROUND
Phenol (carbolic acid) is one of the oldest antiseptic agents. Currently it is used as a disinfectant, chemical intermediate and nail cauterizer. Phenol is a general protoplasmic poison (denatured protein) with corrosive local effects. Phenol derivates are less toxic than pure phenol. The
BACKGROUND
p-Chloroaniline is more potent at producing methemoglobin than aniline in animal models. This case highlights the clinical presentation of an inhalation exposure to p-chloroaniline and associated laboratory analysis. An in-vitro study evaluating the metabolism of p-chloroaniline in human
