Abstract:
Postherpetic itch (PHI) is a common complication of herpes zoster, predominantly affecting the head and face, and significantly impacting patients' quality of life. Few studies have addressed the concerns of PHI, and its available treatments have shown limited efficacy. We report a case of PHI in the trigeminal nerve in which a novel combination of ultra-high-voltage pulsed radiofrequency and escitalopram achieved significant relief of itch. This combined approach may provide a safe and effective option for intractable PHI.

Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...
