Botulism after intragastric botulinum toxin injections for weight reduction.

Although-considering the risk-benefit ratio-botulinum neurotoxin A (BoNT/A) is unequivocally recommended to treat severe neurological diseases such as dystonia, this has not yet been determined for its endoscopic intragastric injection aimed at weight reduction in obesity. However, severe adverse effects of intragastric BoNT/A had not yet been reported, prompting some European countries to endorse its (off-label) use and treat patients transnationally. We here present three cases of botulism after intragastric BoNT/A injections for obesity treatment in a Turkish hospital. Patients presented with cranial nerve affection, bulbar symptoms, and descending paresis, and benefited from treatment with BoNT antitoxin and pyridostigmine. We assume that iatrogenic botulism was induced by overdosing in combination with toxin spread via the highly vascularized gastric tissue. Of note, within a few weeks, more than 80 cases of iatrogenic botulism were reported across Europe after identical intragastric BoNT/A injections. These cases demonstrate the risks of BoNT/A injections if they are not applied within the limits of evidence-based medicine. There is a need for international guidelines to define the indication and a safe dosing scheme, especially in the context of medical tourism.

[Overdosing of direct oral anticoagulants]. / Überdosierung von direkten oralen Antikoagulanzien.

BACKGROUND: Direct oral anticoagulants (DOAC) are increasingly used for prophylaxis and treatment of thromboembolic events. Incorrectly dosed DOAC treatment is associated with excess mortality. PURPOSE: This article aims at raising awareness of DOAC overdosing and its causes as well as presenting a diagnostic and therapeutic work-up. MATERIAL AND METHODS: Based on a case presentation, a structured review of the current literature on DOAC overdosing was performed and treatment recommendations were extracted. RESULTS: In addition to wittingly or unwittingly increased DOAC intake, common causes of overdose are inadequate dose adjustment for concomitant medication or comorbidities. Global coagulation testing should be supplemented with DOAC-specific testing. Severe bleeding and the need for invasive diagnostics or urgent surgery represent indications for treating DOAC overdoses. Based on the cause of an DOAC overdose, active charcoal, endoscopic pill rescue, antagonization with idarucizumab or andexanet alfa and the targeted substitution of coagulation factors represent treatment options. CONCLUSION: The sensitization of clinicians is important to ensure a timely diagnosis and adequate treatment of DOAC overdosing. This report provides an overview of current knowledge on diagnostics and treatment; however, further studies are necessary to improve the existing algorithms.

["Long lie trauma" patients: retrospective analysis of a patient cohort presenting to a university hospital emergency department]. / Liegetrauma: retrospektive Analyse einer Patientenkohorte aus einer universitären Notaufnahme.

BACKGROUND: Patients discovered recumbent, helpless and incapacitated, awake or unresponsive are referred to as "long lie trauma" (LLT) in the German medical jargon. Yet, a characterization of this cohort is missing. METHODS: We retrospectively analyzed all LLT patients admitted to the emergency department of the University Hospital Cologne from July 2018 to December 2020. RESULTS: A total of 50 LLT patients (median age 76 years, median time on the ground 13.5 h) were identified. The FD was most often attributed to primary cerebral causes in 40% of the cases (20% ischemic stroke, 16% intracranial hemorrhage, 4% epilepsy), intoxication/overdose (12%), and trauma (10%). It was often associated with infection (52%), injury (22%), hypovolemia (66%), acute kidney injury (20%), and severe rhabdomyolysis (creatine kinase ≥ 5000 U/l, 21%) as well as severe hypothermia < 32 °C (20%). Overall, 69% of the patients were admitted to an intensive care unit and in-hospital mortality was 50%. CONCLUSION: The term "long lie trauma" describes a complex clinical situation, in which various conditions lead to an incapacitated state with acute onset, which then causes further adverse health effects. Trauma or tissue damage were no obligatory requirement in this syndrome. Considering the high morbidity and in-hospital mortality, patients should initially be treated in the emergency room by an interdisciplinary team.

Higher chance of survival in patients with out-of-hospital cardiac arrest attributed to poisoning.

AIM OF THE STUDY: Description and comparison of cohort characteristics and outcome of adult patients with out-of-hospital cardiac arrest (OHCA) attributed to poisoning (P-OHCA) versus patients with OHCA attributed to other medical causes (NP-OHCA). METHODS: We included all patients who received cardiopulmonary resuscitation after OHCA between January 2011 and December 2020 from German emergency medical services with good data quality in the German Resuscitation Registry. EXCLUSION CRITERIA: patients < 18 years of age or OHCA attributed to trauma, drowning, intracranial bleeding or exsanguination. RESULTS: Patients with P-OHCA (n = 574) were significantly younger compared to NP-OHCA (n = 40,146) (median age of 43 (35-54) years vs. 73 (62-82) years; p < 0.001). Cardiac arrest in P-OHCA patients was significantly less often witnessed by bystanders (41.8 % vs. 66.2 %, p < 0.001). Asystole was the predominant initial rhythm in P-OHCA patients (73.5% vs. 53.7%, p < 0.001) while ventricular fibrillation (VF) and pulseless electrical activity (PEA) were less common (9.2% vs. 25.1% and 16.2 % vs. 20.5%, p < 0.001). P-OHCA had a higher chance of survival with good neurological outcome at hospital discharge (15.2 vs. 8.8 % p < 0.001) and poisoning was an independent protective prognostic factor in multivariate analysis (OR 2.47, 95%-CI [1.71-3.57]). P-OHCA patients with initial PEA survival with good neurological outcome was comparable to initial VF (34.3 % vs. 37.7%). CONCLUSION: Patients in the P-OHCA group had a significantly higher chance of survival with good neurological outcome and PEA as initial rhythm was as favourable as initial VF. Therefore, in P-OHCA patients resuscitation efforts should be extended.

[Update - intoxications in critical care medicine]. / Update ­ Intoxikationen in der Intensivmedizin.

While monitoring and symptomatic care is sufficient for most intoxicated patients, some develop life threatening symptoms. We present recent changes in the recommendations of the treatment in patients with calcium channel blocker, beta blocker and high dose paracetamol intoxications. Additionally, new insights in the efficacy and safety of the use of physostigmine in anticholinergic patients and beta blockers in cocaine intoxication are discussed as well as the specific considerations in the resuscitation of intoxicated patients.

Impairment of Neurocognitive Functioning, Motor Performance, and Mood Stability in Hospitalized Patients With Euvolemic Moderate and Profound Hyponatremia.

BACKGROUND: The impact of chronic moderate and profound hyponatremia on neurocognitive performance, motor skills, and mood stability has not been investigated systematically so far, and results regarding mild to moderate hyponatremia are inconsistent. Furthermore, it is not known whether treatment has an effect on outcome in these patients. METHODS: A total of 130 hospitalized patients with confirmed euvolemic hyponatremia (<130 mEq/L) were subjected to a test battery (Mini-Mental State Examination, DemTect, Trail-Making Tests A and B, Beck Depression Inventory, Timed-up-and-go Test) before and after treatment; additionally, 50 normonatremic group-matched patients served as reference group. RESULTS: The scores of all tested domains were significantly worse in the hyponatremia group (median serum sodium [Na+] 122 (119-126) mEq/L) as compared to the reference group (P <0.001), and the odds of obtaining a pathological test result increased markedly with more profound hyponatremic states (odds ratios between 5.0 and 21.8 in the group with Na+ <120 mEq/L compared to reference group). Inversely, treatment led to a significant amelioration of all test results with medium to large effect sizes. Linear regression models revealed the increment of Na+ as an important predictor of test outcome. CONCLUSION: We demonstrate a clear association between lower levels of Na+ beyond mild hyponatremia and impairment of neurocognitive and motor performance as well as mood disorders. Our analysis further suggests a causal role of hyponatremia in this context. However, there are apparent differences between the distinct tested domains warranting further investigations.
