Sudan black poisoning resulted in methemoglobinemia in a baby with congenital chyloperitoneum.

Treatment of congenital chyloperitoneum is a challenge. Conservative methods may be ineffective. Preoperative visualization of the site of lymphatic leakage is crucial, but radiological imaging is technically complicated and may not provide sufficient information, especially in small patients.

The safe addition of nitric oxide to the sweep gas of the extracorporeal membrane oxygenation circuit in a pediatric cardiac intensive care unit.

Nitric Oxide (NO) is a naturally occurring modulator of inflammation found in the human body. Several studies in the pediatric cardiothoracic surgery literature have demonstrated some beneficial clinical effects when NO is added to the sweep gas of the cardiopulmonary bypass circuit. Our primary aim was to determine the safety of incorporating nitric oxide into the oxygenator sweep gas of the extracorporeal membrane oxygenation (ECMO) circuit.

Causes of acquired methemoglobinemia - A retrospective study at a large academic hospital.

Methemoglobinemia is a potentially life-threatening condition caused by the formation of methemoglobin, a form of hemoglobin that cannot bind oxygen. While there are some rare congenital causes of methemoglobinemia, most cases are acquired from the effects of specific drugs or environmental exposures. In this retrospective study, we analyzed a large data set of whole blood samples analyzed for methemoglobin at an academic medical center in Midwestern United States that provides both pediatric and adult services.

Methylene blue and its potential in the treatment of traumatic brain injury, brain ischemia, and Alzheimer's disease.

Traumatic brain injury (TBI) and brain ischemia/reperfusion cause neurodegenerative processes that can continue after the acute stage with the development of severe brain atrophy with dementia. In this case, the long-term neurodegeneration of the brain is similar to the neurodegeneration characteristic of Alzheimer's disease (AD) and is associated with the accumulation of beta amyloid and tau protein. In the pathogenesis of AD as well as in the pathogenesis of cerebral ischemia and TBI oxidative stress, progressive inflammation, glial activation, blood-brain barrier dysfunction, and excessive activation of autophagy are involved, which implies the presence of many targets that can be affected by neuroprotectors.

Acalypha indica induced acute oxidative haemolysis and methaemoglobinaemia: two case reports.

Background: Herbal products and traditional remedies are commonly used by individuals worldwide for the management of common ailments, even though most are not without risks. Acalypha indica is a popular medicinal plant consumed in some Asian countries.

Case Presentation: This case report presents a 40-year-old previously unevaluated Sri Lankan female and her 8-year-old son who presented with severe glucose-6-phosphate dehydrogenase (G6PD) deficiency related acute intravascular oxidative haemolysis and methaemoglobinaemia precipitated by Acalypha indica consumption, successfully managed with supportive care and blood transfusion.

Zopiclone-Induced Methemoglobinemia: A Case Report Highlighting How the Treatment Differs in Patients on Serotonergic Medication.

Zopiclone is a sedative-hypnotic that is increasingly being used for insomnia, especially among patients with depression. The side effects of zopiclone include nausea, vomiting, headache, giddiness, sedation, altered mental status, and coma. Here, we describe a rare case of a patient with underlying depression who overdosed on zopiclone, resulting in a presentation of drowsiness and dyspnea.

Successful Treatment with Ascorbic Acid in a Case of Methemoglobinemia Due to Glucose-6-Phosphate Dehydrogenase Deficiency.

Anaesthetic Management of Distal Penile Hypospadias in a G6PD-Deficient Adolescent: Subarachnoid Block as a Safe Alternative.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common X-linked recessive red blood cell disease in humans. The highest prevalence of G6PD deficiency is reported to be in Africa, Southern Europe, the Middle East, Southeast Asia, and the islands of the Central and South Pacific. G6PD deficiency causes acute hemolysis upon exposure to oxidative stress.

A Case Report of Primaquine Associated Methemoglobinemia in a Man With Pneumocystis Jirovecii Pneumonia Following Cardiac and Renal Transplantation.

We describe the case of a 51-year-old Caucasian man with a background of a cardiac and renal transplant who developed Enterocytozoon bieneusi colitis and pneumocystis jirovecii (PJP) pneumonia following treatment for suspected rejection. The patient developed methemoglobinemia which was attributed to primaquine. He was treated with intravenous methylene blue leading to clinical and biochemical resolution.

Dapsone-Induced Methemoglobinemia Presenting Concomitantly With COVID-19 Pneumonia and Pulmonary Embolism: A Case Report.

Acquired methemoglobinemia is a treatable condition that is often clinically subtle and can be missed on routine clinical assessment. We present a 73-year-old male who was evaluated in the emergency department with worsening respiratory symptoms requiring oxygen. He tested COVID-19 positive and had new pulmonary emboli evident on his CT chest.

Development of a multivariate predictive model for dapsone adverse drug events in people with leprosy under standard WHO multidrug therapy.

Background: The occurrence of adverse drug events (ADEs) during dapsone (DDS) treatment in patients with leprosy can constitute a significant barrier to the successful completion of the standardized therapeutic regimen for this disease. Well-known DDS-ADEs are hemolytic anemia, methemoglobinemia, hepatotoxicity, agranulocytosis, and hypersensitivity reactions. Identifying risk factors for ADEs before starting World Health Organization recommended standard multidrug therapy (WHO/MDT) can guide therapeutic planning for the patient.

Case Report: Borderline Lepromatous Leprosy Therapy Complicated by Type 1 Leprosy Reaction and Adverse Reactions with Dapsone and Clofazimine.

Leprosy is a global health issue, causing long-term functional morbidity and stigma. Rapid diagnosis and appropriate treatment are important; however, early diagnosis is often challenging, especially in nonendemic areas. Here, we report a case of borderline lepromatous leprosy accompanied by dapsone-induced (neutropenia, anemia, and methemoglobinemia) and clofazimine-induced (skin discoloration and ichthyosis) side effects and type 1 leprosy reactions during administration of the multidrug therapy.

Unravelling groundwater contamination and health-related implications in semi-arid and cold regions of India.

Groundwater, a vital global resource, is essential for sustaining life and various human activities. However, its quality and availability face increasing threats from both natural and human-induced factors. Widespread contamination, arising from both natural origins and human activities such as agriculture, industry, mining, improper waste disposal, and wastewater release, poses significant risks to human health and water security.
