Background: Renal artery thrombosis is rare and limited reports exist in the young population. The most common aetiology is thromboembolic disease or abdominal trauma in this population and isolated occurrences are extremely rare. We present the case of an 18-year-old woman with spontaneous unilateral renal artery thrombosis and infarction for whom reperfusion was achieved through endovascular intervention.

Background: Adherence to antiretroviral treatment (ART) remains the cornerstone of optimal HIV outcomes, including viral suppression (VS), immune recovery, and decreased transmission risk. For many people with HIV (PWH), particularly those with early-acquired HIV, structural, behavioral, and cognitive barriers to adherence and competing priorities related to life events may be difficult to overcome, resulting in nonadherence. Long-acting injectable antiretroviral therapies (LAI-ART) may be a useful strategy to overcome some of these barriers.

The incidence of tickborne diseases in the United States is increasing; reported cases more than doubled from >22,000 in 2004 to >48,000 in 2016 (1). Ticks are responsible for approximately 95% of all locally acquired vectorborne diseases reported by states and the District of Columbia, with Lyme disease accounting for >80% of those cases (2). After a tick bite, persons might seek care at an emergency department (ED) for tick removal and to receive postexposure prophylaxis, which has been shown to effectively prevent Lyme disease when taken within 72 hours of a high-risk bite (3).

Botulinum toxin is frequently used as a therapeutic for a variety of non-FDA approved indications in children. This narrative literature review explores three off-label uses of botulinum toxin in pediatric conditions including congenital muscular torticollis, spastic trismus, and neonatal brachial plexus palsy. While more research is needed to establish treatment, dosing and localization guidelines for the use of botulinum toxin in these commonly treated conditions, available evidence is discussed.

With the American Academy of Physical Medicine and Rehabilitation recently celebrating its 75th anniversary, it is an opportune time to assess the impact and influence that physiatric articles and research have had on the field, as well as the greater scientific community. One useful metric of scientific impact is citation count, which is the most common method for analyzing the magnitude of scientific recognition of an individual article. This study presents 2 reading lists of influential physiatric academic journal articles drawn from the Web of Science index based on citation count.

Forebrain cholinergic neurons play important roles as striatal local circuit neurons and basal telencephalic projection neurons. The genetic mechanisms that control development of these neurons suggest that most of them are derived from the basal telencephalon where Lhx8, a LIM-homeobox gene, is expressed. Here we report that mice with a null mutation of Lhx8 are deficient in the development of forebrain cholinergic neurons.
