Objective: Imidazoline derivatives like naphazoline have a firm place in diagnostics and therapy of otorhinolaryngology because of their vasoconstrictive and decongestive properties. Their alpha-adrenergic potential could induce not only local but also systemic side effects like hypertension and tachycardia which can increase a life-threatening intoxication. Signs of imidazoline intoxication are excessive systolic and diastolic hypertension and hypotension, bradycardia with arrhythmia, respiratory depression, excitation or severe CNS depression.
Patients: The typical course of an intoxication and its sufficient therapy is reported by means of two cases of intraoperative application of naphazoline for hemostasis.
Results: In case of overdosage or intoxication, symptomatic drug therapy with intravenous administration of 5 mg phentolamine for adults and 1 mg phentolamine for infants has to be done. Phentolamine, an alpha-adrenoceptor antagonist, acting against peripheral and central side effects has to be used because no specific antidote is available.
Conclusions: Especially pediatric otorhinolaryngologists have to know about symptoms and therapy of an intoxication after application of naphazoline. Particularly with children, a narrow therapeutic to toxic window can be observed in this frequently used drug.

Adverse drug reactions (ADR) remain a challenge in modern healthcare, particularly given the increasing complexity of therapeutics. WHO's definition of an adverse drug reaction as a response to a drug that is noxious and unintended and occurs at doses normally used in man for the prophylaxis, diagnosis or therapy of disease, or for modification of physiological function. This definition underscores the importance of monitoring and mitigating unintended drug effects, particularly for widely used medications like valproic acid (VPA).

This review explores the therapeutic potential of the stable gastric pentadecapeptide BPC 157 in addressing electrolyte imbalances, specifically hyperkalemia, hypokalemia, hypermagnesemia, and hyperlithemia. In hyperkalemia, BPC 157 demonstrated a comprehensive counteractive effect against KCl overdose (intraperitoneally, intragastrically, and in vitro), effectively mitigating symptoms such as muscular weakness, hypertension, sphincter dysfunction, arrhythmias, and lethality. It also counteracted the adverse effects of succinylcholine and magnesium overdose, including systemic muscle paralysis, arrhythmias, and hyperkalemia.

According to WHO, dengue fever (DF) is currently endemic to more than 100 countries in various regions of Africa, America, and Asia; outbreaks have been reported in Europe. In the Russian Federation, there is a much smaller proportion of children among those infected due to the imported nature of the infection. We described a clinical case of imported dengue fever in an adolescent girl in Moscow after a 5-day vacation.
