The link between reversible cerebral vasoconstriction syndrome and transient global amnesia.

Reversible cerebral vasoconstriction syndrome (RCVS) and transient global amnesia (TGA) are acute and self-limiting intra-cerebral conditions. Although previously studied as independent phenomena, there are increasing reports of co-occurrence of these two pathologies. We report a 55-year-old male who presented to the hospital with recurrent thunderclap headaches over the course of 1 week with sudden onset of anterograde memory loss.

The Effects of Spinal Cord Stimulators on End Organ Perfusion: A Literature Review.

Spinal cord stimulators (SCS) have been gaining momentum in the last decade as their role in the management of chronic pain has become more apparent. Our intention was to search, analyze and highlight the effects of spinal cord stimulators on end-organ perfusion. We also looked at vascular diseases of atherosclerotic and nonatherosclerotic nature by examining objective evidence of improved circulation, pain control, limb salvage, and quality of life.

Methylnaltrexone and Naloxone for Opioid-induced Constipation in the Critical Care Setting.

Opioid antagonists in the ICU are often a last-line medication given to patients with opioid-induced constipation. Traditionally, patients have been administered nonopioid-based bowel regimens such as senna, peg, and docusate to treat constipation. Despite the obvious need to treat acute pain with opioids, side effects such as constipation can lead to multiple gastrointestinal (GI) complications such as bowel perforation and even death.

Neurosyphilis Presenting as Intermittent Explosive Disorder and Acute Psychosis.

We present a case of a patient with tertiary syphilis, manifesting as acute psychosis, auditory hallucinations and intermittent explosive disorder with pending legal ramifications for physical violence. Our patient had been seen and treated by a psychologist with Aripiprazole for his erratic and aggressive behavior coupled with his new found psychosis over a one-year period with no avail. Prior accounts of interaction with the patient described him as "easy going", "laid back", and cooperative.

A Review of Lumbar Radiculopathy, Diagnosis, and Treatment.

We review the epidemiology, etiology, symptomatology, clinical presentation, anatomy, pathophysiology, workup, diagnosis, non-surgical and surgical management, postoperative care, outcomes, long-term management, and morbidity of lumbar radiculopathy. We review when outpatient conservative management is appropriate and "red flag" warning symptoms that would necessitate an emergency evaluation. Diagnostic modalities, including magnetic resonance imaging (MRI), computerized tomography (CT), contrast myelogram, electromyogram (EMG), and nerve conduction velocity (NCV), are involved in the diagnosis and decision-making are discussed.
