A 16-year-old girl working in a paint and dye-casting factory of aniline dyes presented to the emergency with cyanosis, fever and altered sensorium. She had been diagnosed as a case of malaria and treated with chloroquine elsewhere. At admission, her saturation was 79%, which did not improve despite
Acquired methemoglobinemia is a rare but severe condition associated with oxidizing stressors, most notably medications. Although the symptoms can be life threatening, they usually respond promptly to exposure cessation and methylene blue injection. We describe the first case of methemoglobinemia
Naphthalene poisoning is a rare form of toxicity that may occur after ingestion, inhalation, or dermal exposure to naphthalene-containing compounds such as mothballs. Clinically, patients present with acute onset of dark brown urine, watery diarrhea, and non-bloody bilious vomiting 48-96 hours after
This report describes a case of methemoglobinemia in association with dapsone therapy. The patient, an immunocompromised child with chronic immune thrombocytopenic purpura, presented with fever, cough, perioral cyanosis, bilateral lower lobe rales, and low O2 saturation by pulse oximetry (89%). His
We report a novel homozygous mutation responsible for NADH-b(5)R deficiency in a family from Ratnagiri district in western India with recessive congenital methemoglobinemia (RCM) type I. The propositus was a 20-year-old female with a history of increasing cyanosis exacerbated by fever and weakness.
We report a case of blackwater fever with brown plasma due to the presence of methemalbumin. The discovery of plasma with this color is a rare event at the laboratory. This compound appears during intravascular hemolysis or hemorrhagic pancreatitis when the ability of haptoglobin and hemopexin to
Congenital methemoglobinemia is a relatively rare clinical disorder characterized by life-long cyanosis, caused by either an inherited mutant hemoglobin (Hb-M) or deficiency of physiologically active NADH-dependent methemoglobin reductase (NADH-MR). NADH-MR deficiency leads to two different types of
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
Hb-M is a very rare hemoglobinopathy in the Indian subcontinent. We report a family with Hb-M with lifelong cyanosis from the Ratnagiri district in western India. The propositus was a 11-year-old female child with a history of increasing cyanosis exacerbated by fever and weakness. Similar complaints
Dapsone is commonly used for pneumocystis carinii pneumonia (PCP) prophylaxis in immunocompromised patients. It has been used as an alternative therapy in the hematopoietic stem cell transplant (HSCT) setting in patients who can't tolerate trimethoprim-sulfamethoxazole. The Sulfone syndrome is not a
Objective: To evaluate the efficacy of clindamycin-primaquine as the salvage treatment for pneumocystis pneumonia (PCP) in non-HIV-infected patients. Methods: Clinical data of non-HIV-infected patients with PCP who were treated with clindamycin-primaquine as the salvage treatment in Peking
BACKGROUND
Dapsone (diaminodiphenylsulfone) is used for the treatment of intractable skin diseases such as pemphigus and leprosy. The side effects of Dapsone are anemia, leukopenia, and liver dysfunction. Here, we present a case of agranulocytosis-induced septic shock, which was a side effect of
Limited data regarding methemoglobinemia in pregnancy, particularly secondary to dapsone is available up to date. We report a case of dapsone-induced methemoglobinemia in a pregnant mother with multibacillary leprosy who presented with fever, productive cough and cyanosis of 2 days duration 2 weeks
Methylene blue and proflavine are fluorescent dyes used to stain nucleic acid from the molecular level to the tissue level. Already clinically used for sentinel node mapping, detection of neuroendocrine tumors, methemoglobinemia, septic shock, ifosfamide-induced encephalopathy, and photodynamic
