Mucosal leishmaniasis (ML) is a chronic and rare form of leishmaniasis that causes malignant lesions in the mucosa of the nasal, pharyngeal, and laryngeal regions. We describe a 29-year-old woman who had been suffering from an intranasal polyp for 3 years. The polyp recurred annually after surgical removal, and was diagnosed as nasal leishmaniasis.

Opium addiction can cause symptoms in the central or peripheral neurological systems, as well as gastrointestinal disorders and anemia; in such situations, lead poisoning should be considered and chelation therapy should be started as soon as possible. In adults, lead poisoning is an unusual cause of abdominal pain. A common form of lead neuropathy includes weakness of the wrist and finger extensors. We describe a 24-year-old female who developed severe lead poisoning after 3 years of opium consumption, leading to gastrointestinal complaints and bilateral wrist drops. [ABSTRACT FROM AUTHOR]

Propranolol, a β-blocker (BB), is one of the drugs that can be misused for suicide. The clinical manifestations of overdose can range from asymptomatic to neurological symptoms such as seizures and loss of consciousness, cardiac shock, and even death. Herein, we describe 2 cases that were referred to our hospital's emergency department in northern Iran: The first case was a 37-year-old woman who suffered from a decreased level of consciousness, bradycardia, and hypotension after ingesting 4 g of propranolol tablets. In the second case, a 32-year-old woman was admitted with complete cardiac arrest and a suspected history of ingesting 4.8 g of propranolol pills a few hours before admission. Therefore, the time interval between pill intake and treatment initiation seems to be one of the most important factors in prognosis, in addition to the number and dosage of pills ingested.
