Oxalic Acid Poisoning Research Paper

A novel early management strategy for severe toxicity from deliberate oxalic acid ingestion. Abstract Direct oxalic acid poisoning is a recognized cause of deliberate self harm in southern Sri Lanka as it is a component of locally produced household laundry detergent. Here we describe a case of a 23 year old female, presenting following a direct ingestion of oxalic acid. She developed significant metabolic acidosis and hemodynamic instability. In our patient aggressive initial management including acid base control and early use of calcium, appeared to result in a favorable outcome. .

[1] Toxicological effects in humans include hypocalcaemia due to formation of calcium oxalate crystals, renal toxicity and gastrointestinal corrosion. Ingestion of oxalic acid is common in some parts of the Sri Lanka, especially in southern province, where it is a component of household laundry detergen, ‘Prinso’. ‘Prinso’ is supplied as two sachets, one containing 12.5 grams of oxalic acid and the other containing 1.2 grams of potassium permanganate (KMNO4). Although uncommon elsewhere, direct ingestion carries a case fatality rate of 25.4% in Sri Lanka [2]. Here we report a case of deliberate self-poisoning with ‘Prinso’ in which aggressive early management may have been responsible for a favourable outcome. Case History A 23 year old female from a nearby rural community presented to the Emergency Department (ED) of Teaching Hospital, Karapitiya one and a half hours after the ingestion of an entire oxalic acid sachet and half a sachet of potassium permanganate dissolved in a glass of water. Immediately after ingestion, she developed abdominal cramps and

    Assignment #3 Two vitamins that I do not meet the guidelines for daily consumption from the 2010 Dietary Guidelines for Americans are vitamins A and D, which are both fat-soluble vitamins. The primary function of vitamin A is maintaining the function of the cells that line the lungs, stomach, urinary tract and bladder, intestines, vagina, vision, skin and immune function. Having a low intake of vitamin A could increase my risk of vision problems such as age related macular degeneration due an inadequate amount of carotenoids such as lutein, zeaxanthin, and beta-carotenes. The recommended amount for me according the Dietary Reference Intake (DRI) for Vitamin A-RAE is 700 mcg and for my weekly average I consumed 279.2. If this vitamin is taken in excess it can have harmful effects such as liver toxicity and birth defects.

    Chapter five titled “Mercury” of The Poisoner’s Handbook by Deborah Blum gives a fascinating story, about a woman named Gertie Gorman who was married to a man named Charles Webb. Many believed that her husband poisoned her because in her will “[she would leave] everything to her husband” (112) giving him a good motive for that action, but as the investigators opened up the body they found the presence of mercury bichloride, which was a “messy killer” (114) meaning it was hard to miss because of all the bloody inflammations. As the investigators looked more into the case they found out that Webb was not the person responsible for his wife’s death, however Webb was still prosecuted. Mercury can be poisonous if taken in extreme quantities causing the same things it did to Gertie’s body.

    In chapter 6 titled “Carbon Monoxide (CO), Part 1” of The Poisoner’s Handbook by Deborah Blum the most interesting story developed within the chapter was the death of Anna Fredericksen after inhaling carbon monoxide. It was interesting because the way the murder was convicted, it created the impression as if Francesco Trivia had cut her into pieces, making him look like a lunatic killer. As Gettler noted in his inquiry, “In each glass vessel, each ceramic dish, the bloody solutions, instead of turning the darkish grays of normal oxygenated blood, flamed that brilliant red. Her blood was saturated with carboxyhemoglobin.” (Blum 148).
