Abstract 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.

Purpose Intestinal bowel endometriosis is reported in up to 37% of women with proven endometriosis. The aim of this study was to evaluate by colonoscopy and magnetic resonance imaging, patients suspected of deep infiltrating endometriosis (DIE) including the bowel wall that presented with cyclic hematochezia. Methods Twenty-four patients with cyclic hematochezia were retrospectively analyzed on colonoscopic features of colonoscopy, corresponding biopsy data, and outcome of magnetic resonance imaging evaluation. Fifteen out of 24 patients underwent bowel resection because of insufficient response to hormonal treatment (N=14) or obstructive ileus (N=1). Outcome of surgery and histologic examination of the resected specimens were evaluated. Results Colonoscopy proved intestinal endometriosis in only one out of 24 (4%) patients with cyclic hematochezia. In 13 out of 15 bowel resections endometriosis was found at histopathology. The location and dimension of lesions during surgery correlated well with magnetic resonance imaging findings. However, magnetic resonance imaging revealed a limited capacity to detect luminal narrowing of the bowel. Conclusions This study shows that colonoscopic findings of bowel endometriosis are aspecific. Colonoscopy, an invasive investigation, should therefore not be performed to diagnose endometriosis infiltrating the bowel wall. Magnetic resonance imaging provides good diagnostic work-up and in selected patients a roadmap to surgery.

A Prospective Study

Retinal hemorrhages occur frequently in association with abusive head trauma.1 The injuries are venous [See table in the PDF] in origin and, as such, are similar to the retinal hemorrhages which frequently occur in full-term neonates after vaginal delivery. Because retinal hemorrhages in child abuse frequently are associated with intracranial bleeding, we questioned the possibility of a relationship between parturitional retinal hemorrhages and concurrent intracranial injuries. To answer this question we designed a prospective study in which we performed magnetic resonance imaging on 10 randomly selected full-term neonates in whom the presence of retinal hemorrhages was confirmed on fundascopic examination by a pediatric ophthalmologist.
