Methemoglobinemia is a rare but clinically important condition that should be considered among differential diagnosis' in cyanosis. The conventional treatments of methemoglobinemia are high flow oxygen and methylene blue therapies.We present a 52-year-old male patient who admitted to emergency room with severe cyanosis and dyspnea after he was exposed to paint thinner and zinc phosphate solution. The patient was diagnosed with methemoglobinemia with a MetHb level of 49.1mm/Hg in his arterial blood gas test. Patient's symptoms and increased MetHb levels were resistant to high flow oxygen and methylene blue therapies so hyperbaric oxygen therapy (HBO) as an alternative treatment was initiated and the patient was cured promptly.In this case presentation, we aim to discuss the alternative treatment modalities in methemoglobinemia patients with persistent hypoxia and cyanosis, who are unresponsive to standard methylene blue treatment.

There may be three conclusions for the current study: First, although EPA is a rare problem for patients referred to emergency services, health professionals should be suspicious when examining patients 65 years or older because of the difficulties of diagnosing EPA. Second, in patients with no history of suspicious trauma or suspicious radiological imaging results, EPA is also common. Third, because of the undetected EPA mechanism, patients should be examined forensically in suspicious cases and deaths.

The chameleon can disguise itself in nature by taking on different colors and forms. As synthetic cannabinoids (SC) have clinically similar effects to those of several psychoactive agents, they are one of the most difficult intoxications to diagnose. The reasons for this are due to clinical variations throughout the world and the differences in symptoms having not been determined due to their similarity to the intoxication of several other drugs. The aim of this study was to obtain prospective data of patients presenting at the Emergency Department (ED) with suspected SC intoxication, and as a result of prospective examination of samples, to determine a new generation of SC use, SC types, clinical findings, and treatments. Method: A total of a 15 patients with suspected SC intoxication who presented at the ED of the Health Sciences University Kayseri Training and Research Hospital between January 2017 and January 2018 were examined. Samples taken prospectively from patients who were followed-up for a diagnosis of SC intoxication were examined with the HR LC-MS/MS method; SC were determined, and the test results of other psychoactive agents that were used concurrently were examined. Conclusions: Three significant findings emerged as a result of this study. Firstly, due to the different clinical forms of presentation at ED associated with SC use and the range of intoxications that cannot be diagnosed, advanced laboratory tests are required, in addition to routine tests for the determination of SC. Secondly, those diagnosed as having taken SC were also determined to have used it concurrently with substances that have a high potential for addiction, such as amphetamines and quetiapine. Thirdly, in regard to examples of cases presented in the literature, anti-psychotics, fluid hydration, and anxiolytics can be used as treatment options for those diagnosed with SC use.
