Abstract

In 1949, amphetamine sulfate was replaced by propylhexedrine in the nasal decongestant agent Benzedrex because of psychosis, sudden death, and widespread abuse. Propylhexedrine is not without risks, and reported cases of psychosis, myocardial infarction, pulmonary vascular disease and pulmonary hypertension, and sudden death are well documented in the medical literature. We are reporting 2 cases of definite brainstem dysfunction and 5 cases of transient diplopia secondary to IV abuse of Benzedrex. This widely abused drug is prepared by heating Benzedrex and hydrochloric acid, and the resulting crystals are dissolved in water for injection. This agent is called "stove-top speed". All 7 patients had transient diplopia, within seconds after injection. One patient had evidence of a right-internuclear ophthalmoplegia, and another had a depressed right gag reflex and paralysis of the right half of the tongue. The deficits in these two patients, persisted for many months. In young adults with history of drug abuse, the IV use of Benzedrex should be considered in the differential diagnosis of transient or permanent focal brainstem deficits.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Epigenetic memory refers to the heritable genetic changes that are not explained by the DNA sequence. Find the latest research on epigenetic memory here.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
