RM syndrome occurs at a relatively high rate in acute poisonings. Although agent's toxicity is crucial for the outcome, severe RM and its complications may significantly influence the clinical course and prognosis of poisoning. Routine analysis of CK, as a relevant marker for RM may indicate the development of RM in acute poisoning and initiate prompt therapeutic measures in preventing acute renal failure as the most frequent consequence of extensive rhabdomyolysis.

A rising number of patients are being treated for overdosing with new psychoactive substances (NPS) available at the illegal drug market in Serbia. The aim of this study was to report clinical and analytical experience of the National Poison Control Centre of Serbia (NPCC) with synthetic cannabinoids (SCs) and point to the NPS available at the illegal drug market in our country. From January 2013 to December 2016, 58 patients (aged between 14 and 25) were treated for the effects of synthetic cannabinoids at the NPCC. Tachycardia was established in 53, mydriasis in 31, somnolence, nausea, vomiting, and agitation in 16, dizziness in 10, disorientation in 9, dyspnoea and chest pain in 4, and loss of consciousness, pallor, paraesthesia, muscle twitches, and short-term memory impairment in 2 patients. After receiving symptomatic and supportive treatment in the emergency ward, all patients had fully recovered within 8 h and were discharged shortly afterwards. Another part of the study was focused on the analysis of the products known under their local street names as "Biljni tamjan" (herbal incense), "Beli slez", and "Rainbow Special" and the analysis of urine sampled from the patients with gas chromatography - mass spectrometry and high performance liquid chromatography. The detected synthetic cannabinoids were AB-PINACA, JWH-018, JWH-122, JWH-210, 5F-AKB48, and MDMB-CHMICA in herbal products and AB-FUBINACA, AB-CHMINACA, and MDMB-CHMICA in the urine samples. Our findings have shown the great capacity of NPCC to I) monitor NPS abuse in Serbia, II) reliably detect SCs in illicit products and biological samples, and III) clinically manage the adverse effects in their users. Future commitments of the NPCC will include systematic collection of relevant data on SCs and their adverse effects, detection of changes in purity and composition of the controlled NPS-based products, and raising the public awareness of NPS to improve the effectiveness of the national Early Warning System.

Introduction. During the last few years, intravenous lipid emulsions have been effectively used in treatment of acute poisonings with lipophilic substances, including verapamil. Case report. A 37-year-old women presented 1 hour after ingestion of 2.8 g verapamil with hypotension and complete heart block. Because of the applied standard therapy failure and further patients impairment, Intralipid ® 20% was used. Sinus rhythm was restored, arterial blood pressure increased and verapamile concentrations, both total and free decreased. Conclusion. Intravenous lipid emulsion can be important in treatment of severe acute intoxication and cardiotoxicity caused by verapamil.Uvod. Poslednjih godina intravenske emulzije masti uspešno se koriste u terapiji akutnih trovanja lipofilnim supstancama, uključujući i verapamil. Prikaz bolesnika. Prikazana je 37godišnja pacijentkinja primljena jedan sat nakon ingestije 2,8 g verapamila. Na prijemu je bila hipotenzivna, sa kompletnim srčanim blokom. Zbog izostanka efekta primenjene standardne terapije i daljeg pogoršanja stanja pacijentkinje primenjen je Intralipid ® 20%, nakon čega je uspostavljen sinusni ritam. Zabeležen je porast arterijskog pritiska, uz smanjenje koncentracije verapamila, kako ukupnog, tako i slobodne frakcije leka. Zaključak. Intravenske emulzije masti mogu zauzeti važno mesto u terapiji teške akutne intoksikacije i kardiotoksičnosti uzrokovane verapamilom.

Introduction: Ogilvie syndrome and gastrointestinal bleeding as complications after reversal of typical clinical picture of acute Clozapine overdose is described. Case Report: A previously healthy 31-year-old man was found unconscious with Glasgow Coma Score of 6, non-reactive miotic pupils, hypersalivation and heart rate of 115 bpm. In the blood, the presence of Clozapine, Diazepam, haloperidol and biperiden were confirmed. The patient was referred to the intensive care unit for symptomatic and supportive treatment. Clinical signs registered on admission, except for sinus tachycardia, were completely resolved by the day 3. The patient began to eat and had regular bowel movements. From the seventh day, gastrointestinal complications were noticed. Nonobstructive dilatation of the stomach and intestine was confirmed on computed tomography scan. Nasogastric suction, the usage of laxatives and prostigmin injections as well as colonic irrigation was performed with a good clinical response. Conclusion: Clinicians should be aware of the potential of atypical antipsychotics to cause ileus, particulary in combination with other drugs with antimuscarinic properties, and ready to rapidly detect and treat intestinal atony thus preventing life-threatening complications. Serum Clozapine levels may not equate to clinical toxicity and the drug-näive patient require more careful observation for complications in Clozapine toxicity settings.
