BACKGROUND Acute dacryoadenitis is an uncommon disease. CASE We present what we believe to be the first reported case of herpes zoster ophthalmicus with the onset of acute dacryoadenitis. OBSERVATIONS A 30-year-old man complained of severe ocular pain and hyperemia in his right eye. Magnetic resonance imaging (MRI) demonstrated enlargement of the right lacrimal gland and acute dacryoadeniti...

PURPOSE Percutaneous ganglion balloon compression (PBC) is a minimally invasive procedure for treatment of trigeminal neuralgia. MATERIALS AND METHODS Twenty-seven (19 female and 8 male) patients, who presented with classical symptoms of trigeminal neuralgia, were included. Age ranged from 34 to 91 years (median 62 years), 33 procedures were performed. Duration of the symptoms ranged from 1 y...

UNLABELLED Chronic trigeminal pain, with its severe related functional problems, is difficult to treat. Treatment is often empirically based on medications used for other chronic pain conditions. Systemic sodium channel and calcium channel blocking agents may cause a multitude of complications that are often poorly tolerated by the patient. AIM The aim of this case report was to assess the ef...

In three patients, trigeminal sensory symptoms remitted with treatment of associated hydrocephalus, two with facial pain resembling trigeminal neuralgia, and one with facial paraesthesiae. The pathological basis of these phenomena and their relationship to idiopathic trigeminal neuralgia are discussed.

Typical trigeminal neuralgia, brief electric shock like pain along distribution of trigeminal nerve, is well documented in literature but not much is available about pre trigeminal neuralgia. Pre-trigeminal neuralgia should be considered in the differential diagnosis of pain of dental origin because of its similar features.Symonds was the first person who noted dull, continuous and aching pain ...

Previous studies in several different trigeminal nerve injury/inflammation models indicated that the hyperexcitability of primary afferent neurons contributes to the pain pathway underlying mechanical allodynia. Although multiple types of voltage-gated ion channels are associated with neuronal hyperexcitability, voltage-gated K+ channels (Kv) are one of the important physiological regulators of...

Background: Severe pain is present in trigeminal neuralgia and may be devastating and debilitating. There are multiple modalities of nonsurgical techniques to help with pain and functionality. Patient: 47 year old male with 6 year history of facial pain due to trigeminal neuralgia. Treated at outside institution with medical management. Intervention: Left gasserian ganglion pulsed radiofrequenc...

Trigeminal neuralgia is a type of orofacial pain that is diagnosed in 150,000 individuals each year, with an incidence of 12.6 per 100,000 person-years and a prevalence of 155 cases per 1,000,000 in the United States. Trigeminal neuralgia pain is characterized by sudden, severe, brief, stabbing or lancinating, recurrent episodes of pain in the distribution of one or more branches of the trigemi...

Theanine is a non-dietary amino acid linked to the modulation of synaptic transmission in the central nervous system, although the acute effects of theanine in vivo, particularly on nociceptive transmission in the trigeminal system, remain to be determined. The present study investigated whether acute intravenous theanine administration to rats attenuates the excitability of wide dynamic range ...

Brainstem-mediated antinociceptive inhibitory reflexes of the temporalis muscle were investigated in 82 patients (47 F, 35 M, mean age 28.3 years, SD 9.4) with acute posttraumatic headache (PH) following whiplash injury but without neurological deficits, bone injury of the cervical spine or a combined direct head trauma on average 5 days after the acceleration trauma. Latencies and durations of...
