Peripheral and Central Smell Regions in Migraine Patients using Maraş Powder (Smokeless Tobacco): A Magnetic Resonance Imaging Evaluation

Objective In the present study, we investigated the efficacy of Maraş powder (smokeless tobacco) use on smell regions in migraine patients. Methods The cranial magnetic resonance imaging images of 58 adult patients were included in this retrospective study. Thirty-eight of them were migraine patients (18 of them using Maraş powder and 20 of them not using Maraş powder) and 20 of them were healthy controls. Bilateral peripheral (olfactory bulb [OB] volume and olfactory sulcus depth) and central smell regions (insular gyrus area and corpus amygdala area) as well as nasal septal deviation were evaluated. Results In migraine patients (using or not using Maraş powder), OB volumes, and in Maraş powder using migraine patients, corpus amygdala areas were lower than those in the control group (p < 0.05). In Maraş powder-using migraine patients, left insular gyrus areas of the females were significantly lower than the males (p < 0.05). Conclusion We concluded that the peripheral smell region of the OB volume decreased in migraine patients (using or not using Maraş powder). However, the central smell region of corpus amygdala area decreased in Maraş powder using migraine patients. Maraş powder usage may increase vascular shrinkage, and the decrease in OB volume and corpus amygdala area becomes prominent. It can be said that Maraş powder usage may cause a size decrease in the peripheral and central smell regions in migraine patients. Therefore, migraine patients and non-migrainous people should be noticed for the harmful effects of Maraş powder on the vascular system and smell system in the aspects of OB volume and corpus amygdala area decrease.

Assessment of Children Exposed to Maras Powder Intoxication

Introduction: A smokeless tobacco known as Maras powder (MP) is commonly consumed in the southern region of Turkey. To the extent of our knowledge, no previous study in literature has reported acute MP intoxication in children. Aim: Our aim was to determine the clinical effects and treatment strategies of MP poisoning in children.Materials and methods: We retrospectively reviewed the medical records of children <18 years of age with MP intoxication who were followed up in the Intensive Care Unit between January 2016 and April 2018 in our center. Results: Forty-one patients (M/F= 25/16) were included in this study. The mean age was 13.2&plusmn;22.4 months (age range: 7 to 30 months). The patients presented with vomiting (n=23, 56%), cough (n=17, 41.5%), loss of consciousness (n=11, 26.8%), respiratory distress (n=6, 14.6%), convulsion (n=7, 17%), cyanosis (n=1, 2.4%), and abdominal pain (n=1, 2.4%) following oral ingestion of the substance. On their physical examination all patients with convulsion were in a comatose state. Thirty-two patients (78%) had tachycardia; 15 patients (36.5%) had pharyngeal hyperemia; and three (7.3%) had hiccups. Although the female patients had a lesser rate of symptoms than male patients, the difference was not statistically significant. Conclusions: Our aim was to inform the doctors about the clinical picture that develops after taking this substance and contribute to the understanding of the treatment approach.
