MAIN OUTCOME MEASURES: Main outcome measures included the frequency, severity, and duration of ocular complications, patient reports of zoster-associated pain, and the outcome of skin lesions. [ncbi.nlm.nih.gov]
Even after she discontinued treatment with allopurinol, her skin lesions progressed to a severe blistering skin eruption. After the patient started oral prednisone therapy, her skin lesions resolved with desquamation. [jamanetwork.com]
Transmission is via respiratory droplets, aerosolized vesicular contents, or direct contact with skin lesions. After infection, VZV becomes latent in sensory ganglia, with reactivation possible even decades later. [pedsinreview.aappublications.org]
Treatment is with antiviral drugs, ideally given within 72 hours after skin lesions appear. [merckmanuals.com]

Lesions begin as macules, progressing to papules, then vesicles. Initially, lesions are 2- to 4-mm, thin-walled, irregular vesicles with clear fluid over an erythematous base, classically described as “dewdrops on a rose petal.” [pedsinreview.aappublications.org]

In the emergency department, the patient underwent septic workup, including lumbar puncture, with normal cerebrospinal fluid analysis results. He was admitted to the hospital. High-grade fever abruptly resolved on day 3 of hospitalization. [emedicine.medscape.com]
Fever of unknown origin was defined as fever ≥100 o F on two occasions during any 48 hr period for which an etiology could not be determined despite 3 days of appropriate diagnostic workup ( 19 ). [journals.lww.com]

Two cells (centre-left) have the characteristic (cytoplasmic) viral inclusion bodies (small pink globules ). H&E stain. CMV infection can be demonstrated microscopically by the detection of intranuclear inclusion bodies. [en.wikipedia.org]
Treatment
The current study was not designed to assess the effects of the treatments on postherpetic neuralgia (PHN). [ncbi.nlm.nih.gov]
Adequate diagnostics and rapid antiviral treatment are essential for the outcome. [tidsskriftet.no]
Topical acyclovir is intended for treatment of minor mucocutaneous HSV infections and plays no role in treatment of VZV. Herpes sores heal after 3-4 days but often recur. Treatment relieves pain and discomfort but cannot prevent recurrence. [lianavargas.com]

Prognosis
The four patients with encephalitis had a less favorable prognosis: one patient recovered without residual neurological sequelae; two had a chronic neuropsychological handicap, speech difficulties, facial nerve palsy, and focal seizures; one patient died [ncbi.nlm.nih.gov]

Although the prognosis of meningitis is good, encephalitis and myelitis often result in sequelae, and a delay in the initiation of acyclovir treatment leads to poor prognosis. [intechopen.com]
As with other herpesviruses (eg, CMV) that can reactivate and are believed to contribute to a worse prognosis in these patients, the association has not been shown to be causal (see Prognosis). [emedicine.medscape.com]
What Is the Prognosis for Shingles? What Are Possible Shingles Complications? Many cases of shingles go away by themselves, with or without treatment. The rash and pain should be gone in two to three weeks. [emedicinehealth.com]
