Fatal aconite poisoning in a rural Nepali traditional healer: clinical challenges and management strategies.

Introduction and importance: Aconite, also known as Aconitum spp., is a group of highly toxic flowering plants used historically in traditional medicine despite their potent neurotoxic and cardiotoxic effects. In rural Nepal, where traditional healing practices are prevalent, accidental ingestion of Aconite remains a significant public health concern due to its resemblance to medicinal herbs. Case presentation: The authors present a case of severe Aconite poisoning in a 45-year-old male traditional healer from rural Nepal. Following ingestion of a homemade herbal tea containing Aconitum species, the patient developed rapid-onset symptoms, including paresthesia around the mouth, severe abdominal pain, and progressive weakness. Upon admission, he exhibited signs of cardiovascular compromise and metabolic acidosis. Despite aggressive management, including gastric lavage, fluid resuscitation, and symptomatic treatment, the patient succumbed to cardiovascular collapse within 12 h of admission. Clinical discussion: Aconite poisoning manifests with early neurological symptoms and progresses to severe gastrointestinal and cardiovascular complications. Its toxicity is attributed to aconitine, which disrupts cellular function by binding to voltage-gated sodium channels. Management focuses on supportive care and symptomatic treatment, given the absence of a specific antidote and challenges in rural healthcare settings. Conclusion: This case underscores the critical need for awareness among healthcare providers and the public regarding the dangers of Aconite. Improved education, healthcare infrastructure, and early intervention are essential in mitigating the morbidity and mortality associated with Aconite poisoning in resource-limited settings.

A Case Presentation in Management of Dysphagia and Dysarthria Caused due to Organophosphorus and Carbamate Insecticide Poisoning.

Organophosphorus and carbamate Insectiside is common in Asia-Pacific region consisting of 63% of the Global death. Organophosphorus and Carbamate poisoning can lead into different complications in the respiratory,digestive,neurological aspects and maybe fatal in certain cases.Besides medical management of the same,early rehabilitation is also required to manage different kinds of neurological aspects caused due to Organophosphorus and carbamate poisoning. The study was done to introspect the early intervention in swallowing and speech therapy in organophosphorus and carbamate poisoning individual,as a part of management besides medical intervention. A 19 years old female reported to the hospital with history of consuming organophos and carbamate insecticide with the intention of self harming causing cardiac arrest and as diagnosed as Flaccid Dysarthria with Oro-Pharyngeal Dysphagia when assessed with diagnostic tools respectively. Early speech and swallowing intervention was provided and introspected using MASA which showed improvement in scores during the therapeutic intervention and was statistically analysed using linear regression analysis. The result showed the improvement in MASA scores (the slope of the best fit) and proved that MASA scores improved significantly (slope = 14.3, p < 0.05) over time as the therapy sessions proceeded. The regression model was also significant (p < 0.05). The motor-speech therapeutic intervention provided improvement in the kinematics of oro-motor skills along with improvement in intelligibility of speech. This study concludes that early intervention in managing speech and swallowing abilities in Dysarthria and Dysphagia is helpful besides medical intervention in such cases.

The trajectory of serum salicylate concentrations after ingestion of medicinal oil containing methyl salicylate.

INTRODUCTION: The toxicokinetics of methyl salicylate after unintentional or intentional ingestion of medicinal oil containing methyl salicylate has not been well studied. We aimed to characterize the trajectory of serum salicylate concentrations and to evaluate factors associated with the peak serum salicylate concentration and the time from ingestion to peak concentration. METHODS: This was a retrospective cohort study of consecutive patients reported to the Hong Kong Poison Control Centre for laboratory-confirmed methyl salicylate poisoning by all local public emergency departments between 1 July 2008 and 30 June 2023. We analyzed cases with at least three serum salicylate concentrations. Multivariable generalized linear regression was used to identify factors significantly associated with the peak serum concentration and the time from ingestion to peak concentration. RESULTS: We included 41 patients (median age 81.0 years; 32 women and nine men). The median time from ingestion to the first peak serum salicylate concentration was 5.6 h (IQR: 3.2-10.8 h). Multiple regression showed that gastric aspiration (adjusted regression coefficient [ß] - 2.50; 95% CI: -3.93 to -1.08; P = 0.001) and single-dose activated charcoal (adjusted ß - 1.22; 95% CI: -2.02 to -0.42; P = 0.003) were significantly associated with a lower peak concentration, after adjusting for patient age, sex, exposure due to intentional self-harm, reported ingested dose, time from ingestion to emergency department presentation, vomiting, concurrent use of aspirin (acetylsalicylic acid) and other medications that affect gastric emptying or gastric acid secretion, blood pH, serum albumin concentration, and creatinine clearance. DISCUSSION: The serum salicylate concentration did not peak as quickly as generally believed, highlighting the importance of continued monitoring. Gastric aspiration and single-dose activated charcoal may help reduce gastrointestinal absorption, but their impact on clinical outcomes remains unclear. CONCLUSIONS: Given the median time of 5.6 h (IQR: 3.2-10.8 h) from ingestion to the peak salicylate concentration, gastric aspiration and single-dose activated charcoal can be considered in patients up to a few hours after medicinal oil ingestion when the airway is protected.

Faster ciguatoxin extraction methods for toxicity screening.

Ciguatera poisoning (CP) is a severe global public health problem caused by the consumption of seafood products contaminated with ciguatoxins (CTXs). The growing demand for seafood products requires high-throughput testing for CTX-susceptible seafood, however complex extraction and slow cleanup methods inhibit this goal. Herein, several methods for extracting CTXs from fish tissue were established and compared; these methods are sensitive, specific, and valid while achieving higher sample extraction throughput than currently established protocols. The trial fish material was generated from multiple species, with different physical conditions (wet and freeze-dried tissue), and naturally contaminated with various CTXs (i.e., CTX-1B, CTX-3C, and C-CTX-1), thus ensuring these methods are robust and broadly applicable. The extraction methods used were based on mechanical maceration with acetone or methanol or enzymatic digestion followed by acetone and ethyl acetate extraction. Crude extracts were investigated for CTX-like toxicity using an in vitro mouse neuroblastoma (N2a) cell-based assay (CBA). Among the three methods, there was no significant difference in toxin estimates (p = 0.219, two-way ANOVA), indicating their interchangeability. For speed (> 16 samples/day), accuracy (100%), and CTX analog retention confirmation by liquid chromatography-tandem mass spectrometry (LC‒MS/MS), the preferred extraction methods were both methanol and enzyme-based. All extraction methods post hoc confirmation of CTX analogs successfully met international seafood market-based CTX contaminant guidance. These methods can drastically increase global CTX screening capabilities and subsequently relieve sample processing bottlenecks, inhibiting environmental and human health-based CTX analysis.

Self-poisoning with paracetamol in England: short report of characteristics of individuals and their overdoses according to source of tablets.

Self-poisoning with paracetamol is the most frequently used overdose method in the UK. Psychosocial assessments were conducted by mental health clinicians with 127 consecutive individuals who presented with pure paracetamol overdoses to a large general hospital over 8 months, including asking about the source of the tablets and scoring the patients' acts on the Beck Suicide Intent scale (BSI). Patients were predominantly female (86%) and young (79% aged 12-24 years). Most had used paracetamol which was available in the home (77%). Those who purchased paracetamol for the act took double the number of tablets compared with those who used paracetamol available in the home (37 v. 18), had higher suicidal intent (mean BSI: 11 v. 7) and more often required treatment with N-acetyl cysteine (71% v. 43%). These results highlight the need for safer home storage of paracetamol and consideration of reducing pack size limits on paracetamol that can be purchased.

Unintentional poisoning in older Australians: a retrospective audit of New South Wales Poisons Information Centre data.

INTRODUCTION: Poisons information centres provide phone-based risk assessment and management advice on poisonings. Unintentional poisonings are a common reason for consulting a poisons information centre, and older adults are at increased risk of unintentional poisoning and adverse outcomes. We describe patterns of unintentional poisoning in older adults reported to a regional poisons information centre. METHODS: We conducted a retrospective audit of poisons information centre call records and identified unintentional poisonings involving older adults (≥75 years) over a 12-month period to determine patient demographics and poisoning circumstances (substances, contributing factors, and disposition recommendation). Univariate analyses identified variables associated with hospital referral and multivariate models to identify independent risk factors in home-dwelling older adults. RESULTS: We identified 2,757 calls. More exposures occurred in women (62%) and involved therapeutic errors (70.8%). Paracetamol was the most common drug involved (11%), and cardiovascular drugs were the most common drug class (36%). Only 14.3% of the study population was referred to hospital. Independent risk factors for hospital referral in home-dwelling older adults were exposure to cardiovascular, centrally acting and antihyperglycaemics, non-oral route of administration and symptoms at the time of the call. DISCUSSION: Unintentional poisoning is not uncommon, and our findings are similar to those in other countries over recent decades. These findings suggest that unintentional poisoning in older adults is inadequately addressed by current medication safety strategies. Our findings indicate the value of timely advice by poisons information centres for preventing potentially unnecessary hospitalizations. CONCLUSION: Further research is needed to identify more effective approaches to medication safety strategies for older adults. Poisons information centre data contribute to pharmacovigilance activities and could inform patient care.

A Scientific Review of Pesticides: Classification, Toxicity, Health Effects, Sustainability, and Environmental Impact.

Over the years, the use of pesticides has risen significantly, primarily to combat undesirable organisms that threaten crucial crops. A variety of pesticides are available, each designed to protect crops from specific threats like fungi, bacteria, and other pests. Other than crop protection, pesticides are also used in controlling insect vector-borne diseases like malaria and Lyme disease in humans. However, the application of these pesticides must be carefully measured and managed to prevent adverse effects on humans, non-target animals, and the environment. This review delves into the detailed classification of pesticides, exploring their mechanisms of action, applications, benefits, and potential side effects. Understanding the different categories of pesticides, such as herbicides, insecticides, fungicides, rodenticides, and biopesticides, helps us comprehend how each function to control pests. Additionally, we discuss the advantages of pesticide use, including increased crop yields and the prevention of crop diseases, which contribute to food security and agricultural productivity. This review also addresses the significant concerns related to pesticide usage, such as the development of pest resistance, health risks to humans through exposure and residues in food, as well as the impact on biodiversity and ecosystems. The review emphasizes the importance of using pesticides responsibly and implementing integrated pest management strategies to mitigate this risk of exposure. By providing a comprehensive overview of pesticide classification, mechanisms of action, and implications, this review aims to inform and guide us to the safe and effective use of pesticides for daily agricultural practices.

A clinical warning in the treatment of chlorfenapyr poisoning.

Chlorfenapyr, an arylpyrrole-based insecticide, disrupts mitochondrial oxidative phosphorylation to deprive the target organism of energy. Chlorfenapyr poisoning in humans causes distinct clinical signs such as hyperhidrosis, malignant hyperthermia, rhabdomyolysis, and delayed neurological symptoms that worsen over time and can be fatal. When treating acute chlorfenapyr poisoning, physicians must consider the latent period and not assume that a patient is safe after an initial response to treatment. It is important to take measures before sudden, fatal symptoms appear. This paper presents three cases of chlorfenapyr poisoning as a warning for physicians to understand its clinical course and treatment.

A case of acute lithium poisoning and hypermagnesemia involving advanced colon cancer-induced colonic obstruction.

An 83-year-old woman presented with disturbance of consciousness and hand tremor. She had taken lithium carbonate 300 mg/day for bipolar disorder and magnesium oxide 660 mg/day for constipation. Blood tests revealed lithium poisoning, hypermagnesemia and acute kidney injury. Computed tomography showed colonic obstruction caused by cancer of the descending colon. In the outpatient section, her blood pressure decreased to 89/54 mmHg, and her heart rate dropped to 40 bpm. We considered that the obstructive ileus induced intravascular dehydration, which led to toxic serum concentrations of lithium and magnesium, triggering the emergence of severe arrythmia induced by sinus dysfunction. The patient was treated with fluid resuscitation and hemodialysis, followed by endoscopic stent replacement for the descending colon cancer obstruction. These treatments improved her general condition and alleviated the lithium poisoning, hypermagnesemia and colonic obstruction. Such a case is considered extremely rare.

Isovaleramide attenuates ethylene glycol poisoning-induced acute kidney injury and reduces mortality by inhibiting alcohol dehydrogenase activity in rats.

We explored the potential value of the alcohol dehydrogenase (ADH) inhibitor isovaleramide (ISO) in the treatment of acute ethylene glycol (EG) poisoning-induced acute kidney injury. Sprague-Dawley rats were divided into the control, EG, EG + ISO (10 mg/kg) and EG + ISO (20 mg/kg) groups. It is found that ISO intervention significantly reduced the ADH activity in liver tissue by using visible spectrophotometry, inhibited the in vivo metabolism of EG by using gas chromatography, lowered the levels of toxic metabolites glycolic acid and oxalic acid by using high-performance liquid chromatography and decreased the expression of kidney injury markers serum creatinine (sCr), KIM-1, neutrophil gelatinase-associated lipocalin (NGAL) and liver fatty acid-binding protein (L-FABP) by ELISA. Additionally, Western blotting results showed that ISO down-regulated the expression of apoptotic factors Bax and cleaved caspase-3 in the kidneys and upregulated the expression of antiapoptotic factor Bcl-2. Pizzolato staining and polarized light microscopy results revealed the reduced deposition of calcium oxalate crystals in the kidney tubules. Using haematoxylin and eosin (H&E), periodic acid-Schiff (PAS) and Masson staining, we found attenuated kidney tissue pathological injury. Finally, ISO significantly reduced the mortality rate. In conclusion, ISO has the potential to be a valuable drug for the treatment of EG poisoning-induced acute kidney injury.

Association between relatively low blood lead levels and urinary δ-aminolevulinic acid concentrations among male workers at a Japanese battery factory.

OBJECTIVES: Whether the known positive association between blood lead (PbB) levels and urinary δ-aminolevulinic acid (ALAU) also exists at relatively low PbB levels (<40 µg/dL) remains unclear. We aimed to investigate this association at lower PbB levels. METHODS: We analyzed data from biannual medical examinations of workers at a Japanese factory from August 2013 to August 2023. We excluded records from female workers and those with missing data, resulting in a dataset consisting of 1396 records from 155 male workers. We employed mixed-effect linear regression models with a random intercept for workers and additional adjustments for age and smoking status. RESULTS: The median PbB level across all the analyzed records was 8 µg/dL (range: 1-31 µg/dL). Significant positive associations were observed between PbB and ALAU, with a 1-unit increase in natural logarithm-transformed PbB corresponding to a 10.0% increase in ALAU (95% CI, 2.7%-17.9%). Categorized PbB analyses showed a 23.8% increase in ALAU (95% CI, 2.7%-49.2%) for PbB levels at 20-24 µg/dL and an 83.1% increase (95% CI, 30.1%-157.7%) for PbB levels ≥25 µg/dL, compared with those <5 µg/dL. The exposure-response curve analysis indicated a plateau followed by an increasing trend. CONCLUSIONS: A positive and nonlinear association between PbB and ALAU levels was observed at relatively low PbB levels.

Hepatic portal venous gas after ingesting glyphosate: A case report and literature review.

Background: Glyphosate is a widely used herbicide. Clinical presentations of glyphosate intoxication show variation, but hepatic portal venous gas(HPVG) caused by glyphosate poisoning is rarely reported. Herein, we report a rare case of ominous HPVG after ingesting glyphosate. HPVG, which used to be an ominous abdominal radiologic sign, is associated with numerous underlying abdominal pathologies, ranging from benign conditions that require no invasive treatment to potentially lethal diseases that necessitate prompt surgical intervention. Case summary: A young woman who ingested 100 mL glyphosate 6-h prior was admitted to the emergency intensive care unit. Before admission to our hospital, the patient was administered gastric lavage treatment with 10000 mL of normal saline in the local hospital. After 14 h, her laboratory examinations showed systemic inflammatory response syndrome and multiple organ dysfunction syndrome, while the condition deteriorated. Computed tomography of the abdomen showed multilinear air densities in the portal vein, hepatic branches, and mesenteric vessels, intestinal obstruction, and intestinal necrosis. Septic shock and a severe abdominal infection were diagnosed. The patient was treated conservatively as they could not tolerate surgery and, after 20 h died of septic shock. Conclusion: We reviewed 289 cases of "hepatic portal venous gas" in PUBMED and analyzed the etiology and treatment of HPVG accompanied by the underlying pathology. We concluded that HPVG is a radiological sign associated with various diseases, and the prognosis mainly depends on the underlying cause and clinical condition. As glyphosate may erode the digestive tract, attention should be paid to the volume, pressure, and speed of gastric lavage in treating glyphosate poisoning to avoid fatal complications such as HPVG. Abdominal symptoms need to be closely observed, and changes in the early onset of the condition in clinical practice need to be responded to promptly.

[Acute kidney injury caused by acute dimethyl oxalate poisoning: a case report].

Dimethyl oxalate is one of the occupational toxic chemicals and causes strong renal toxicity. On May 16, 2023, a patient with acute dimethyl oxalate poisoning was admitted to Dingxi People's Hospital. The patient presented with nausea, vomiting, lumbar distension, weakness, poor appetite, anuria, and rapidly progressing acute kidney injury. Renal biopsy confirmed acute oxalate nephropathy. After symptomatic supportive treatments such as blood purification, anti-oxidative stress, glucocorticoid, fluid supplementation, alkalized urine, anti-infection, controlling blood pressure, calcium supplementation and anemia correction, the patient's symptoms disappeared, and the kidney function basically returned to normal. This case suggested that the etiology of patients with acute kidney injury must be clearly identified, and renal biopsy was an important examination method. For patients suffering from acute dimethyl oxalate poisoning, comprehensive treatment based on blood purification should be performed as soon as possible, aiming to improve the prognosis.

[A case of recurrent convulsions caused by acute sulfuryl fluoride gas poisoning].

Sulfuryl fluoride is a kind of pesticide with strong permeability, convenient use at low temperature, non-corrosive and other characteristics, which can kill food pests and has strong lethality to termites. In acute sulfuryl fluoride poisoning, patients can see recurrent convulsions, epileptic electroencephalogram abnormalities such as matrix spikes or high amplitude spikes. In this paper, a patient with sulfuryl fluoride poisoning with convulsion-based mental system symptoms was reported, and after clinical treatment with dexamethasone and phenobarbital sodium, the patient was cured and discharged.

Mad honey (wild honey) poisoning: clinical case series from Nepal.

Introduction: Mad honey is commonly used for hypertension, and coronary artery disease, and as a sexual stimulant. Patients with mad honey poisoning present with dizziness, nausea, syncope, blurred vision, bradycardia, and hypotension with ECG findings of sinus bradycardia, complete AV block, and ST elevation. Case discussion: Here, the authors report five cases admitted to our tertiary care center following the consumption of mad honey. The amount of ingestion of honey varies from 1 to 2 teaspoons (~10-20 ml). Most of the cases presented with chief complaints of nausea, dizziness, and vomiting, and all the cases had hypotension and bradycardia. Two cases were admitted to the ward and three of them were admitted to the ICU for further management. They were managed with intravenous fluid, injection atropine along with adjunctive vasopressor and oxygen whenever necessary. Discussion: Mad honey contains grayanotoxin extracted from the nectar of Rhododendron species. This honey contains grayanotoxin, which binds to sodium channels in its open state causing hyperpolarization of the sodium channel predominantly causing gastrointestinal, neurological, and respiratory symptoms. Intravenous fluids and injection atropine are the mainstays of management in an ICU setup. Some also may require vasopressors. Conclusion: Mad honey poisoning is rare, and limited cases have been reported in Nepal. Physicians should consider mad honey poisoning in cases with ingestion history and clinical symptoms, as it may be a clinical diagnosis due to limited lab tests for grayanotoxin intoxication. Supportive management still forms the cornerstone for its management after diagnosis.

High lead contamination in Mother's breastmilk in Bihar (India): Health risk assessment of the feeding children.

Lead poisoning in the recent times has caused serious health threats in the exposed human population. It is estimated that about 815 million people are exposed to lead poisoning worldwide and in India total 275 million children are exposed to blood lead contamination. The present study was carried outed in 6 districts of Bihar to know the extent of lead exposure in the children through their mother's breastmilk. The biological samples such as breastmilk, mother's urine, child's urine, and mother's blood samples were collected for quantitative lead estimation. Moreover, the selected household water sources (handpump) and the food consumed by the individuals-wheat, rice and potato samples were also collected for lead quantification. The study reveals that the breastmilk had high lead content in 92% of the samples (highest value 1309 µg/L), in blood presence of lead was observed in 87% studied samples (highest value 677.2 µg/L). In mother's urine the highest lead value was 4168 µg/L (62%) and in child's urine the highest value was 875.4 µg/L (62%) respectively of the studied samples. Moreover, in the studied food samples, wheat had lead content in 45% the studied samples (highest value 7910 µg/kg). In rice in 40% of the studied samples (highest value 6972 µg/kg) and in potato 90% of the studied samples (highest value = 13786 µg/kg) were found with elevated lead content respectively. The hazard quotient (HQ) and the cancer risk (CR) for lead contamination was very much higher in mothers followed by their children. The entire study indicated that lead exposure through food (wheat, rice and potato) has reached the mother's breastmilk and from their it has reached their child's body. This could cause serious hazards in the exposed children causing serious neurological damages, low IQ, low memory, and low mental growth in them. Therefore, a strategic action is required to control the present problem.

Ethnic-racial disparities in poisoning cases: analysis of drugs of abuse, medicines and pesticides in Brazil.

In Brazil, ethnic-racial inequalities exist in all fields, obstructing access to goods, services, and opportunities, including healthcare services. However, there are no apparent studies that assess, at a national level, ethnic-racial disparities in poisoning cases, emphasizing skin color as a determining factor. The study aimed to examine the relationship between race/ethnicity and general poisoning cases, by medications, pesticides, and drug of abuse in Brazilian states. Poisoning cases data were extracted for the years 2017, 2018, and 2019. Notification data for general poisoning cases and toxic agents were collected: medications, pesticides, and drugs of abuse. Data were categorized between whites and non-whites (blacks, browns, and indigenous) and without information on skin color/ethnicity. Rates of poisonings amongst ethnic-racial groups and cases of not declared skin color as well as relative risk (RR) of poisoning among non-whites were calculated. All states in the North, Northeast (states with the worst Human Development Index), Midwest, and 2 states in the Southeast exhibited higher rates of poisoning cases per 100,000 inhabitants among non-whites. The RR values for nonwhite individuals were higher in the North and Northeast regions for all types of poisonings. The type of poisoning cases that presented the highest RR for non-whites over the 3 years was drugs of abuse (2-2.44), when compared to other types of poisonings from pesticides (2-2.33) and medications (1.5-1.91). The spatial distribution of poisoning cases rates and RR of nonwhite population support public policies to reduce socioeconomic and environmental inequalities.

Attempted Self-Harm with Elemental Thallium Purchased Online: Case Report with Analytical Confirmation.

INTRODUCTION: Thallium is a highly toxic metal, with most publications demonstrating poisoning from thallium salts. We report on a patient with elevated serum and urine thallium concentrations from an intentional ingestion of elemental thallium purchased from the internet for self-harm. CASE REPORT: The regional poison center was contacted about an 18-year-old man who ingested a fragment from a 100-gram bar reported to be elemental thallium. Serial serum and urine thallium concentrations were obtained. Prussian blue was started on hospital day (HD) 2. A metal fragment was seen on abdominal x-ray and removed via colonoscopy on HD3. The ingested fragment was analyzed via inductively coupled plasma mass spectrometry (ICP-MS) and found to be 87.0% elemental thallium. The initial serum thallium concentration obtained on HD1 was 423.5 mcg/L (reference range < 5.1 mcg/L), which subsequently decreased to 4.5 mcg/L, 29 days after the ingestion. An initial random urine thallium concentration obtained on HD 3 was 1850.5 mcg/g creatinine (reference range < 0.4 mcg/g creatinine). The patient remained hospitalized for 23 days and, when seen in follow-up, had not developed any signs or symptoms of thallium toxicity. DISCUSSION: Elemental thallium ingestion is a rare toxicologic exposure, with limited published clinical and analytical experience to guide management. This case report describes a patient with ingestion of elemental thallium who developed elevated serum and urine thallium concentrations and was treated with Prussian blue. Despite having elevated serum and urine thallium concentrations consistent with previous fatal exposures, more evidence is needed to understand the differences between elemental thallium and thallium salts.

Association of Acute Kidney Injury with Ammonia Poisoning: A Case Report.

Ammonia may cause poisoning due to inhalation or ingestion. Renal involvement in ammonia poisoning has been reported only once. A 30-year-old male working in an ice factory was accidentally exposed to liquid ammonia from a leaking hose, following which he had burns over his face and neck and severe abdominal pain. On day 2, he had deranged renal function, which was progressive. He was referred to us due to persistent renal dysfunction. A kidney biopsy was performed due to slow recovery of renal failure, which was suggestive of acute tubular necrosis. He was managed conservatively and showed gradual improvement over 12 days of his hospital stay. Renal functions normalized after 14 days of discharge. This case highlights the occurrence of renal involvement in ammonia poisoning.
