RESUMEN
Mad honey intoxication (MHI) is a food-induced clinical condition that usually presents with cardiovascular symptoms and can lead to life-threatening arrhythmias if not diagnosed and treated early. No data exist in the literature on the presence of interatrial block (IAB) after food intoxication. In our study, we sought to investigate atrioventricular electrocardiography (ECG) parameters and determine the frequency of IAB in patients with MHI. In total, 76 patients diagnosed with MHI were included in our retrospective study. Twelve-lead ECGs were performed and participants were divided into two groups according to the presence of IAB in the reference ECG. The P maximum (Pmax), P minimum (Pmin), P dispersion (Pdisp), T peak to T end (Tp-Te) interval and QT dispersion (QTdisp) values were compared between the two groups. IAB was detected in 28 (35.5%) of 76 MHI patients included in the final analysis. Pmax duration (122 ± 8; p < 0.001) and PD (69 ± 11; p < 0.001) were significantly higher in the IAB ( +) group. During regression analysis, Pmax [odds ratio (OR) 1.158, 95% confidence interval (CI) 1.036-1.294; p = 0.010] and Pd (OR 1.086, 95% CI 1.001-1.017; p = 0.046) were independently associated with IAB. Pmax and Pd area under the receiver operating characteristic curve values for IAB prediction were 0.926 (95% CI 0.841-1,000; p < 0.001) and 0.872 (95% CI 0.765-0.974; p < 0.001), respectively. ECG changes are common in patients presenting with MHI. These patients need to be followed up clinically in terms of progression to arrhythmic events that may occur in the future.

Honey poisoning cases occur in southwestern China. In this case series, we attempted to determine the symptoms and causes of honey poisoning from 2007 to 2012 in southwestern China. We also conducted a quantitative melissopalynological analysis of honey samples. During the study period, 31 honey poisoning cases occurred in the study location, all during July to August. All the cases occurred after consuming at least 100 grams of honey. The most frequent symptoms were nausea and vomiting (100%), abdominal pain (90.3%), diarrhea (74.2%), palpitations (61.3%), dizziness (54.8%), chest congestion (48.4%) and dyspnea (48.4%). Severe cases developed oliguria/anuria, twitch, hematuria, ecchymosis or hematochezia. The median time from ingestion to onset of symptoms was 29 hours. Eight patients died (mortality rate: 25.8%). The pollen of Tripterygium hypoglaucum (a plant with poisonous nectar and pollen) was detected in 22 of 29 honey samples examined (75.9%). The results of pollen analysis were consistent with the clinical findings of previous cases. T. hypoglaucum appears to be the cause of honey poisoning in southwestern China. Honey poisoning should be included in the differential diagnosis of patients who consume honey in this region and develop symptoms of food poisoning.

Mad honey poisoning has been reported in many countries, and it seldom results in death. We describe a rare case series of fatal honey poisoning caused by Tripterygium wilfordii Hook F (TwHF) in Southwest China. Three male construction workers were delivered to the emergency department with symptoms of food poisoning after ingestion of wild raw honey. Laboratory results showed that the 3 patients were at different degrees of renal damage, and 1 patient with severe symptoms died of acute renal failure 1 day after admission. Pollen analysis indicated that the suspected honey was heavily contaminated with TwHF pollen. Early diagnosis and prompt treatment are crucial for such poisoning. Pollen analysis is a practical approach to help diagnosis in remote areas where such honey poisoning occurs.

BACKGROUND: Mad honey-related intoxication frequently leads to bradycardia, hypotension, and syncope. Hypothermia is a potentially life-threatening condition if not identified early and treated appropriately. CASE REPORT: Three patients are reviewed. Patient 1 was a 66-year-old man who presented to the emergency department with nausea, vomiting, and faintness beginning 2 h after consuming honey. His temperature was 34°C, his blood pressure was 70/40 mm Hg, and his heart rate was 30 beats/min. Patient 2, a 57-year-old man, presented to the emergency department with headache, feeling cold, and faintness beginning 3 h after consuming honey. His temperature was 35°C, his blood pressure was 60/40 mm Hg, and his heart rate was 46 beats/min. Patient 3 was a 79-year-old woman who presented with nausea, vomiting, and headache 2 h after consuming honey. Her temperature was 35°C, her blood pressure was 70/40 mm Hg, and her heart rate was 40 beats/min. All 3 patients were discharged in good condition after appropriate therapy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Bradycardia and hypotension are frequently encountered in mad honey intoxication. However, intoxication accompanied by hypothermia has attracted little attention to date.

OBJECTIVE: This study aims to investigate the demographic, toxicological characteristics of the mad honey intoxication at ages 65 and above, to analyze the electrocardiographic parameters, and to compare with the mad honey intoxication at ages below 65 years. PATIENTS AND METHODS: Eighty-two patients, who had been treated and followed-up between June 2013 and November 2014 in the Emergency Service of the Findikli State Hospital, Turkey, due to diagnosis of mad honey intoxication, were included in our observational study. Age, gender, toxicological characteristics, laboratory parameters, heart rates, systolic and diastolic blood pressures, laboratory analyses and electrocardiographic data of the patients were recorded and analyzed. Patients with known coronary artery disease, chronic renal failure, arrhythmias, valvular heart disease, history of thyroid disease and electrolyte imbalance were not included in the study. RESULTS: Eighty-two (80.5% was male and the mean age was 53 ± 15 years) patients followed-up due to mad honey intoxication were included in our study. There were 64 (78%) patients aged below 65 years, and 18 (22%) patients aged 65 and above. The mean heart rate was 45 ± 7 beats/min, systolic blood pressure was 83 ± 12 mmHg and diastolic blood pressure was 52 ± 9 mmHg on admission. The onset of symptoms of the patients was found as 0.84 hours on average after mad honey consumption, the average amount of honey consumed was 3.7 ± 1.1 tablespoons, and the mean recovery time of the symptoms was found to be 1.04 hours. The most common presenting symptoms were nausea-vomiting in 82 (100%) patients and dizziness in 73 (89%) patients. Patients were found to consume mad honey mostly for achieving a remission in gastrointestinal complaints (n=18, 22%), and for utilizing its blood pressure lowering properties (n=11, 13.4%), in addition to the dietary consumption. Looking at the heart rates of the patients on admission to the emergency service, 65 (79.3%) patients had normal sinus rhythm/sinus bradycardia, 12 (14.6%) patients had a 1st degree atrioventricular block, 3 (3.7%) patients had nodal rhythm, 1 (1.2%) patient had atrial fibrillation and 1 (1.2%) patient had preexcitation. There were no significant pathological findings in the routine laboratory examinations of patients. It was found that all patients achieved normal sinus rhythm and normal blood pressure values after medical treatment, and were discharged approximately 5.65 hours after observation and follow-up. In our study, prolonged intensive-care need, pacemaker need and mortality caused by mad honey intoxication were not found. In the comparison of data of all patients above and below 65 years of age, there was a statistically significant finding that the geriatric patients consume mad honey mostly for hypotensive purposes and gastrointestinal complaints; in addition, the symptoms were starting early and the recovery period was longer in geriatric patients. CONCLUSIONS: The mad honey poisoning should be considered in previously healthy patients with unexplained symptoms of bradycardia, hypotension, and atrioventricular block. Therefore, diet history should carefully be obtained from the patients admitted with bradycardia and hypotension. And, in addition to the primary cardiac, neurological and metabolic disorders, mad honey intoxication should also be considered in the differential diagnosis. In geriatric patients admitted due to mad honey intoxication, the mad honey is usually consumed to reduce blood pressure and resolve gastrointestinal problems; and, their symptoms begin early, and last longer after mad honey consumption. In terms of other parameters, the geriatric age group has similar characteristics to non-geriatric age group.

BACKGROUND AND OBJECTIVE: Intoxications related to "mad honey" are frequently encountered in the Black Sea region of Turkey. Intoxication is established on the basis of whether honey was consumed when history was taken at presentation. The search for a simple and reliable method for showing the grayanotoxins (GTXs) in mad honey in body fluids and in honey consumed by patients is still at the research stage. The purpose of this preliminary study was to investigate GTX levels in blood, urine, and honey consumed by patients with mad honey intoxication and to determine whether there is an association with clinical status. DESIGN AND SETTINGS: This descrptive study was conducted at the department of Emergency Medicine of Karadeniz Technical University Medical Faculty in Turkey. Mad honey, blood, and urine samples were obtained from patients between September 2013 and October 2014. METHODS: Four cases presenting the Department of Emergency Medicine and diagnosed with mad honey intoxication were included in the study. GTX levels in blood, urine, and honey consumed by patients were determined using liquid chromatography-tandem mass spectrometry. RESULTS: Patients' mean blood GTX I level was 30.62 ng/mL, GTX III level 4.917 ng/mL, urine GTX I level 0.447 mg/mL, and GTX III level 1.998 mg/mL. The mean GTX I level in the honey samples consumed was 4.683 mg/g and GTX III level 8.423 mg/g. CONCLUSION: The present study is unique in representing the first time that GTXs have been determined in human body fluids. There is now an urgent need for a large series of studies to provide statistical evidence whether there is a relationship between levels of toxins in human body fluids and clinical picture.

OBJECTIVE: This study is aimed at analyzing the demographic and clinical characteristics, as well as the hematological-biochemical parameters of patients who admitted to the hospital with the diagnosis of mad honey poisoning. MATERIALS AND METHODS: A total of 16 patients who were admitted with mad honey intoxication symptoms and treated in Emergency Department of Sakarya Education and Research Hospital between January 2009 and December 2012 were included in the study. Demographic and clinical characteristics of the patients and hematological, biochemical parameters were obtained from hospital records. Heart rate, systolic and diastolic blood pressure on admission and at discharge were obtained retrospectively. RESULTS: Sixteen patients (10 males and 6 females, mean age 58.5 ± 10 years, range between 41 and 79) were included in our study. Heart rate was 42 ± 6 beats/min, systolic blood pressure was 73 ± 19 mmHg, and diastolic blood pressure was 45 ± 17 mmHg on admission. In the evaluation of the patients' heart rhythms on admission to the emergency room, nine (56.3%) patients had sinus bradycardia, three (18.8%) patients had nodal rhythm, two (12.5%) patients had first degree atrioventricular block, and two (12.5%) patients had atrial fibrillation. Atropine 1.1 ± 0.4 mg and saline 1125 ± 465 ml were used to treat patients. Patients were discharged with a stable condition after an average 27.7 ± 7.2 h of follow-up. Heart rate was 75 ± 8 beats/min, systolic blood pressure was 132 ± 7 mmHg, and diastolic blood pressure was 82 ± 6 mmHg at discharge. Mortality was not observed. Hematological and biochemical parameters measured at the time of admission were within normal ranges. CONCLUSION: Mad honey poisoning should be considered in previously healthy patients with unexplained symptoms of bradycardia, hypotension, and cardiac dysrhythmias. Therefore, diet history should carefully be obtained from the patients admitted with bradycardia and hypotension, and mad honey intoxication should also be considered in the differential diagnosis, as well as primary cardiac, neurologic, and metabolic disorders. Mad honey poisoning may be presented with life-threatening symptoms without any hematological and biochemical disorder.

A 52-year-old man with Turkish background presented with nausea, emesis, one experience of syncope with loss of consciousness for a few seconds, and documented sinus bradycardia. During monitoring, several phases of bradycardia were observed. After 24 h of monitoring, the patient was free of complaints. The patient's wife reported regular consumption of pontin honey. Because of the anamnesis and the typical characteristics, grayanotoxin poisoning was diagnosed. Typical symptoms of this poisoning are hypotension, bradycardia, syncope, and loss of consciousness. When these symptoms are found and a typical anamnesis exists, this kind of intoxication has to been taken into consideration as part of the differential diagnosis.

The aims of this study were to evaluate the clinical characteristics and outcomes of patients with grayanotoxin poisoning due to mad honey brought from Nepal. Medical records of patients with mad honey poisoning admitted to the emergency department between 1 January 2004 and 31 May 2012 were retrospectively reviewed. A total of 15 patients were included in this study. In all patients, mad honey was brought from the Himalayan region of Nepal. The mean age was 52.2 years, and 66.7 % were men. The mean amount of mad honey ingested was 47 cc, and the mean time from ingestion to onset of symptoms was 36 min. In all patients, initial vital signs showed hypotension and bradycardia. The initial electrocardiogram showed sinus bradycardia in eight patients, junctional bradycardia in four patients, complete atrioventricular block in two patients, and atrial fibrillation with slow ventricular response in one patient. Four patients were treated with intravenous normal saline solution only. Eleven patients were treated with intravenous normal saline solution and intravenous atropine sulfate in a dose ranging from 0.5 to 2.0 mg. In all patients, the blood pressure and pulse rate returned to normal limits within 24 h. There were no deaths. The clinical characteristics and outcome of grayanotoxin poisonings caused by the ingestion of mad honey from Nepal are similar with those of mad honey from the Black Sea region of Turkey.

OBJECTIVE: This study was designed to analyze the characteristics of adult patients with mad honey intoxication, with special emphasis on its effects on vital signs and blood glucose levels. METHODS: Patients admitted to the Emergency Department of urban hospital in the Black Sea region of Turkey over the 16-months study period due to mad honey intoxication were included. Patients' demographic and clinical characteristics, including age, sex, systolic and diastolic blood pressure, rhythm at ECG, heart rate, blood glucose levels and clinical outcomes were recorded and analyzed. RESULTS: Forty-six patients with a presumptive diagnosis of mad honey poisoning were recruited. Mean age was 52.2 (±17.2). Blood glucose level was normal in 28 cases (60.9%) and high in 18 (39.1%). Systolic blood pressure (SBP) was low in 40 patients (87%) and normal in six (13%). Diastolic blood pressure (DBP) was low in 42 cases (91.3%) and normal in four (8.7%). Mean glucose level in patients with low SBP was 116.1 (±52.9) mg/dL, vs. 120.7 (±23.0) mg/dL in those with normal or high SBP (p = 0.389). Mean glucose level in patients with low DBP was 118.7 (±51.4) mg/dL, compared to 96.0 (±22.8) mg/dL in those with normal or high DBP (p = 0.146). Heart rate was below or equal to 45 bpm in 28 patients (60.9%). Complete (third degree) heart block was diagnosed in one case. CONCLUSION: Mad honey was found not to cause significant decreases in blood glucose levels in humans. Hypotension, bradycardia and related clinical consequences are commonly encountered in patients diagnosed with mad honey or grayanotoxin poisoning.

We report a case of acute poisoning in a 48-year-old man who presented with chest pain, abdominal pain, dizziness, sweatiness, blurred vision, and severe hypotension after ingestion of honey. His electrocardiogram showed sinus bradycardia and transient ST elevation. He made a good recovery after treatment with atropine and close monitoring. Grayanotoxin was detected in his urine and the honey he ingested, which confirmed a diagnosis of mad honey poisoning. This is a condition prevalent in the Black Sea region around Turkey but rarely seen locally. Although mad honey poisoning is life-threatening, early use of atropine is life-saving. Such poisoning may present with ST elevation in the electrocardiogram and symptoms mimicking acute myocardial infarction. It is therefore essential for clinicians to recognise this unusual form of poisoning and avoid the disastrous use of thrombolytic therapy.
