Acute compartment syndrome refers to ischemic tissue damage secondary to elevated pressures in the enclosed compartments of the lower legs or forearm. When the tissue pressure in an enclosed compartment exceeds the perfusion pressure, the resulting diminished tissue perfusion and compromised blood flow to the muscles and nerves inevitably lead to ischemic tissue necrosis. Majority of the cases involving the lower extremities are due to a traumatic event, most commonly tibial fractures. Other causes include a crush injury or other long bone fractures in a motor vehicle accident, a tight cast or dressing after trauma, and drug overdose.

-Tibial stress fractures are common in athletes and nonathletes who suddenly increase their physical activity. Clinical features include pain, localized tenderness, and swelling. Plain x-ray is <50% sensitive for stress fractures, especially in the first 2-3 weeks after the onset of symptoms. MRI is preferred over bone scan or ultrasound as it can show the fracture line that extends through the cortex into the medullary line. MRI can also identify ligament, muscle, and cartilage injuries. However, MRI findings may be persistently abnormal for up to 1 year after the stress fracture has healed.

Lithium, a mood stabilizer used in bipolar disorder, has a narrow therapeutic index (small difference between therapeutic and toxic levels}. This patient's gradual onset of neurologic symptoms (slurred speech, confusion, tremors, and ataxia) is consistent with chronic lithium toxicity. Therapeutic lithium levels are 0.8- 1.2 mEq/L. Serum lithium levels >1.5 mEq/L confirm toxicity, and levels ;::2 .5 mEq/L require emergency management.

Benzodiazepines are a class of agents that work on the central nervous system, acting selectively on gamma-aminobutyric acid-A (GABA-A) receptors in the brain. GABA is a neurotransmitter that inhibits or reduces the activity of nerve cells (neurons) within the brain. Benzodiazepines open GABA-activated chloride channels, and allow chloride ions to enter the neuron. This makes the neuron negatively charged and resistant to excitation.

The fuel for the process leading to orgasm is testosterone, a hormone produced in steady supply by the testicles. The testicles also make millions of sperm each day, which mature and then are mixed with whitish, protein-rich fluids. These fluids nourish and support the sperm so they can live after ejaculation for a limited time. This mixture of fluid and sperm, known as semen, is what is moved through the urethra and out the penis during orgasm.
