Signs herpes outbreak is coming

A 60 year old male patient reported to the OPD of our college, with a chief complaint of painful ulcers on right side of face and in upper right back region of jaw since 7 days. The patient’s initial or primary VZV infection is called chicken pox and usually occurs during childhood.
This particular virus is responsible for the acute onset of chicken pox, usually occurs in children and young adults.
Congenitally acquired herpes zoster in the newborn occurs due to transplacental infection with varicella -zoster virus .
Kerato-conjunctivitis in ophthalmic lesions may cause scarring and blindness due to progressive ophthalmic involvement. Ramsay Hunt syndrome (RHS)- first described by James Ramsay Hunt in 1907, [11] is caused by reactivation of VZV which lies latent in sensory root ganglion for years in a patient who had chickenpox earlier.
The dermatomal pattern of distribution and the appearance of the herpes zoster rash are so distinctive that the diagnosis usually is clear.
Controversial results have been mentioned in various studies due to their high risk of inducing post herpetic neuralgia. In 2006, the Food and Drug Administration licensed the vaccine Zostavax® to be used to prevent shingles in patients who are 60 years of age or older.
Herpetic eye disease or ocular herpes refers to any eye problem due to infection by the herpes simplex virus.
The herpes simplex virus, like the herpes zoster virus, can affect any part of the eye, from the front (eyelids) all the way to the back (retina). Primary herpes infection: This is when the herpes simplex virus infects the patient for the first time, usually during childhood. Acute retinal necrosis: The retina is the light-sensitive innermost lining of the eyeball, which detects, absorbs and processes the light that enters the eye.
The definitive way to diagnose herpetic eye disease is by taking a sample from the eye for analysis with polymerase chain reaction (PCR).
Mild ocular herpes tends to resolve spontaneously over several weeks without any treatment.
Anti-viral treatment: This is the mainstay of therapy, and can be in the form of eye drops (trifluorouridine), eye ointment (aciclovir), or tablets (aciclovir, famciclovir, and valaciclovir). Steroid eye drops: In general, steroid eye drops are not a good idea because they reduce the immune response of the eye to the infection. Lubrication: Eyes with previous or current active herpetic eye disease tend to have dryness of the ocular surface, which can slow down the healing process. Corneal graft: Corneal transplant surgery is indicated when the herpes simplex infection has resulted in severe scarring of the cornea. With keratoconus, as the cornea protrudes or steepens, vision becomes increasingly blurred and contact lens wear, which is often an early treatment for the disease, becomes difficult.
A person with Fuchs' endothelial dystrophy or bullous keratopathy may first notice glare with lights at night or in bright sunlight.
Fuchs' endothelial dystrophy is a hereditary abnormality of the inner cell layer of the cornea called the endothelium.
Cataract and intraocular lens implant surgery: Bullous keratopathy occurs in a very small percentage of patients following these procedures.
Certain eye diseases, such as retinitis pigmentosa, retinopathy of prematurity, and vernal keratoconjunctivitis.
Systemic diseases, such as Leber's congenital amaurosis, Ehlers-Danlos syndrome, Down syndrome and osteogenesis imperfecta. Your eye doctor can check for corneal disease and trauma by examining your eyes with magnifying instruments.

Initially patient developed fever which was followed by intense itching and burning sensation on right side of face. During healing, the patient’s immune system is only rarely able to totally eliminate VZV from the body.
Herpes zoster is a continuation of this infection as the virus is not eliminated from the body but becomes latent in the cranial nerves, dorsal roots, nerve cell bodies or autonomic ganglion. The incidence of postherpetic neuralgia increases with age and is uncommon in patients younger than 60 years (Table 1[10]). Involvement of geniculate ganglion of sensory branch of facial nerve leads to herpes zoster oticus (HZO) also known as RHS. In cases where the diagnosis is in doubt, polymerase chain reaction (PCR) techniques are the most sensitive and specific diagnostic tests; however, these techniques are not widely available.
Valacyclovir and famciclovir usually are preferred because they are administered three times daily as opposed to acyclovir, which must be given five times daily.
But, in immuno compromised elderly patients corticosteroids along with antiviral drugs have proved to be useful in healing and crusting of lesions.


For those who underwent vaccination against chicken pox, their risk of developing shingles appears to be lower than those who were exposed to chicken pox naturally.Prevention of varicella is very important in neonates and immunocompromised individuals. Prevelance of postherpetic neuralgia after a first episode of herpes zoster: prospective study with long term follow up. There are 2 main types of herpes simplex virus: herpes simplex virus 1 (which causes mouth ulcers and herpetic eye disease), and herpes simplex virus 2 (which causes genital ulcers and rashes).
After causing the initial infection, it remains quiescent within the nervous system of the host but it can reactivate and cause problems. Your ophthalmologist will use the tip of some cotton wool (or tissue) to gently touch the front surface of the cornea. If the herpes simplex virus DNA is detected, then the diagnosis of herpes simplex infection is confirmed. However, if the cornea is affected, it is generally a good idea to start treatment to reduce the risk of corneal scarring. For dendritic ulceration, the anti-viral eye drops or ointment are instilled at least 5 times daily for a few days; this is then reduced or stopped according to clinical response.
However, once the anti-virals get the infection under control, the steroid eye drops will help to settle any inflammation in the eye and promote recovery. Actively lubricating the eyes with preservative-free eye drops or gels or ointment (the lubricants are the same as those used for dry eye treatment), help with the recovery process.
This involves removing the unhealthy, scarred cornea and replacing it with normeal, healthy cornea from a donor. As these conditions progress, vision may be foggy or blurry in the morning and clear up as the day progresses. The purpose of this layer is to pump fluids out of the cornea, keeping it thin and crystal clear. This occurs because the inner layer of the cornea, the endothelium, has been damaged and is no longer pumping fluids out of the tissue. Using a slit lamp and advanced diagnostic technology such as corneal topography, your doctor can detect early cataracts, corneal scars, and other problems associated with the front structures of the eye. Although corneal transplant is almost always the necessary treatment to restore vision when the cornea becomes clouded, there are other measures that can be taken to prolong vision in the early stages of disease. Of Oral And Maxillofacial Surgery - Maitri College Of Dentistry And Research Centre3 Post Graduate Student , Dept. The varicella-zoster virus (VZV) is a member of the human herpes virus family and is responsible for causing chicken pox and herpes zoster. However, in most cases the immune system forces the virus into a dormant or latent state within the nerves. The disease is most common in adult life and affects males and females with equal frequency.
Congenital varicella zoster may be acquired by transplacental varicella-zoster virus infection .
Herpes zoster lesions can become secondarily infected with staphylococci or streptococci, and cellulitis may develop.
Involvement of facial nerve leads to otalgia, lower motor neuron homolateral facial paralysis, and vesicular eruptions in auricle.
Passive immunization is by administering varicella zoster immunoglobulin (VZIg) to abort or modify the clinical infection and should be administered within 4 days of exposure to the infected case. It is estimated that one third of the population worldwide suffers from recurrent herpes infections.
The rash and vesicles (see left) can be uncomfortable, but tend to resolve by themselves after several weeks.
As a result, the cornea becomes very dry and the corneal epithelium degenerates (see left; white arrow), thus exposing the corneal tissue underneath to further infection and trauma. This is uncommon, and tends to happen more in people who already have a depressed immune system, such as HIV patients or transplant patients who are on strong anti-rejection medications. The sample can be from the conjunctiva (conjunctival swab), the anterior chamber (aqueous tap), and the vitreous cavity (vitreous tap). Steroid eye drops are particularly useful when there is herpetic stromal keratitis or uveitis.
Corneal disease is a serious condition that can cause clouding, distortion and eventually blindness.
As the diseases further progress, vision will stay blurrier later into the day and eventually may not clear at all. When the endothelium is not healthy, fluids are not pumped out and the cornea develops swelling, causing it to become cloudy and decrease vision. After dilating your eyes, your doctor will also examine your retina for early signs of disease.
Most of the living adults are exposed to VZV naturally and thus, are at risk for developing recurrence, a condition called herpes zoster .


Some vesicles soon ruptured forming painful ulcers on right side of face and on palate (Fig.
If the immune system becomes weakened in the future, VZV may be reactivated to cause the recurrent infection known as shingles.[2] It occurs during the lifetime of 10%-20% of individuals and the prevalence of attack increases with age.
The manifestations that appear after birth are cutaneous scars, limb and eye abnormalities . Herpes zoster involving the ophthalmic division of the trigeminal nerve can lead to ocular complications and visual loss, so referral to an ophthalmologist is recommended. Viral culture has a low sensitivity because the herpes virus is labile and difficult to recover from the vesicular fluid.
Active immunization with a live attenuated VZ virus reduces the risk of acquiring infection; however it should be given within 48 hours to high risk individuals. Slawson, Herpes Zoster and Postherpetic Neuralgia: Prevention and Management, Am Fam Physician.
In severe cases, the corneal tissue may become permanently scarred or be thinned to the point of perforation. In very severe disease, such as acute retinal necrosis, the anti-viral will need to be given directly into the bloodstream (intravenous administration). About 10% to 20% of patients harboring latent VZ virus will develop herpes zoster and this risk increases with age. The direct immunofluorescent antigen-staining test has a higher sensitivity and is more rapid than culture; it provides an alternative diagnostic test when PCR is not available (Table 2 [12],[13],[14]).
The three major types are keratoconus, Fuchs' endothelial dystrophy and bullous keratopathy. Unique feature of this disease includes blisters or sores which are most often confined to one side of the body and usually trace out a predictable pattern. With varicella tendency to follow a dermatome around the body, it is clear to what cingulus refers.
During initial viral replication active ganglionitis develops with resultant neuronal necrosis and severe neuralgia. It is an acute infectious viral disease of an extremely painful and incapacitating nature which is characterized by inflammation of dorsal root ganglia, or extramedullary cranial nerve ganglia, associated with vesicular eruptions of the skin or mucous membranes in areas supplied by the affected sensory nerves[1]. Herpes zoster is contagious to those who have not had varicella or have not received the varicella vaccine.
On clinical examination several clusters of vesicles and ulcers were seen on right side of face. As the virus travels down the nerve the pain intensifies and is described as burning, tingling, itching, boring, prickly, or knifelike[8].
Since a large percentage of the population already has been exposed to Chicken pox, most people harbor an immunity, and the probability that anyone will develop this disease depends more on the state of their immune system than on recent exposure to the virus[4].
On intra oral examination, several white vesicles along with erythematous, shallow ulcers on right side of palate in the region of 15 16 17 18 were seen. Approximately 500,000 cases of herpes zoster occur in the United States each year.[5] In one large study[6] of primary care patients, the annual incidence was two per 1,000 persons. The skin eruption usually is limited to a single dermatome; the most commonly involved dermatomes are the thoracolumbar region and the face.
The initial rash is erythematous, with multiple maculopapular lesions that subsequently become vesicular, The appearance of the cutaneous rash due to herpes zoster coincides with a profound VZV-specific T-cell proliferation.
Based on patient’s history and clinical examination provisional diagnosis was made as herpes zoster.
The patient has a long-lasting, enhanced, cell-mediated immunity response to VZV.The lesions are limited to one side of the body and do not cross the midline.
The oral lesions are 1-4mm, white, opaque vesicles that rupture to form shallow ulcerations.
Several reports have documented significant bone necrosis with loss of teeth in areas involved with herpes zoster. Because of close anatomic relationship between nerves and blood vessels, inflammatory processes within nerves have the potential to extend adjacent vessels.
It is postulated that the gnathic osteonecrosis may be secondary to damage of the blood vessel supplying alveolar ridges and teeth, leading to focal ischeamic necrosis. In children the clinical picture may manifest with erythema multiform-like reaction characterized by sudden appearance of round red papules. Erythema multiforme may be recurrent in the spring or precipitated by exposure to sunlight or after corticosteroid treatment .
