Pain-related reorganization in the primary somatosensory cortex of patients with postherpetic neuralgia.

Hum Brain Mapp 2022 Jun 25. Epub 2022 Jun 25.

CAS Key Laboratory of Behavioral Science, Institute of Psychology, Beijing, China.

Studies on functional and structural changes in the primary somatosensory cortex (S1) have provided important insights into neural mechanisms underlying several chronic pain conditions. However, the role of S1 plasticity in postherpetic neuralgia (PHN) remains elusive. Combining psychophysics and magnetic resonance imaging (MRI), we investigated whether pain in PHN patients is linked to S1 reorganization as compared with healthy controls. Read More

[Herpes Zoster Ophthalmicus presenting as acute headache].

Andes Pediatr 2022 Apr;93(2):270-275

Hospital Universitario Francisco de Borja, Valencia, España.

Herpes Zoster (HZ) is rare in childhood and is defined as the reactivation of the latent varicella-zoster virus in patients who have previously been infected with varicella. When the virus affects the ophthal mic nerve it is called herpes zoster ophthalmicus (HZO) and it can produce, among other symptoms, acute headache, so it must be considered as a differential diagnosis.

Objective: To describe a clinical case of HZO in a pediatric patient and to recognize its clinical manifestations and their importance in the differential diagnosis of acute headache in children. Read More

Trigeminal extracranial thermocoagulation along with patient-controlled analgesia with esketamine for refractory postherpetic neuralgia after herpes zoster ophthalmicus: A case report.

World J Clin Cases 2022 May;10(13):4220-4225

Department of Anesthesiology and Pain Medicine, The Affiliated Hospital of Jiaxing University, Jiaxing 314000, Zhejiang Province, China.

Background: Primary trigeminal neuralgia can achieve satisfactory results through clinical treatment and intervention. The pathogenesis of neuralgia caused by varicella-zoster virus infection of the trigeminal nerve is more complex, and it is still difficult to relieve the pain in some patients simply by drug treatment or surgical intervention.

Case Summary: A 66-year-old woman was hospitalized with herpetic neuralgia after herpes zoster ophthalmicus (varicella-zoster virus infects the ophthalmic branch of the trigeminal nerve). Read More

Support Vector Machine versus Multiple Logistic Regression for Prediction of Postherpetic Neuralgia in Outpatients with Herpes Zoster.

Pain Physician 2022 05;25(3):E481-E488

Department of Anesthesiology, Beijing Friendship Hospital, Capital Medical University, Beijing, China.

Background: Postherpetic neuralgia (PHN), as the most common complication of herpes zoster (HZ), is very refractory to current therapies. Studies of HZ have indicated that early aggressive pain interventions can effectively prevent PHN; therefore, accurately predicting PHN in outpatients with HZ and treating HZ promptly, would be of great benefit to patients. Multiple logistic regression (MLR) has often been used to predict PHN. Read More
