The predictive value of the glossopharyngeal nerve in Chiari 1 malformation with bulbar syndrome has been poorly explored in literature.…”

This experiment was designed to study the effects of caffeine on the histomorphology of the testes of prepubertal male Wistar rats. Prepubertal Wistar rats (25-28 days old), weighing between 50-60 g were randomly divided into three treatment groups (B, C and D) and control (A) of ten rats each. Group A rats received distilled water while Groups B, C, and D rats were respectively given daily dose of 50 mg/kg, 100 mg/kg, and 200 mg/ kg of caffeine dissolved in distilled water for 14 days by gavage. Five rats from each group were sacrificed 24 hours after the last caffeine administration while the remaining rats were monitored for another three weeks for them to attain sexual maturity. The rats were sacrificed under diethyl ether anesthesia and the testes were fixed by immersion in Bouin's fluid. The tissues were processed for histomorphological and histomorphometric assessment. Data obtained were analyzed using one way ANOVA followed by Dunnett post hoc test for comparison with control. Alpha level was set at 0.05. Results showed that treatment with caffeine caused a significant decrease in testicular weight and a marked cellular degenera-tion and depletion of germ cells in the testes of rats in group D. The height of the germinal epithelium was significantly reduced when compared with control. This study concluded that prepubertal exposure of Wistar rats to caffeine reduced testicular growth and deleteriously alters testicular morphology.

“…The morbidity of GPN is 0.2 -0.4/100,000 person-years [1]. The causes of GPN include tumor, infection, Chiari malformation, infarction and vascular compression, and so on [3]- [6]. The clinical manifestation of GPN is unilateral glossopharyngeal or auditory paroxysmal severe lancinating pain, which can be provoked by swallowing, chewing and cough.…”

Glossopharyngeal neuralgia (GPN) refers to paroxysmal severe pain located to glossopharyngeal part or ear, which is a rare clinical event. In this report, we describe a patient suffered from glossopharyngeal neuralgia due to vertebrobasilar dolichoectasia (VBD). A 72-year-old Chinese male was referred to our clinic with a complaint of paroxysmal severe pain in the right external auditory canal and auricle since 1 month, which could be precipitated by feed and accompanied with the vagus nerve irritation (bradycardia, low blood pressure, syncope) sometimes. Both computed tomographic angiography and digital subtraction angiography demonstrated a VBD (maximum diameter 5.7 mm) and a large fusiform aneurysm of basilar artery (maximum diameter 13.8 mm). The diagnosis is established on clinical and radiological signs. This is the first report of this kind in the literature. Although a few cases demonstrate that VBD can cause GPN, it should be considered as a possible etiology in patients with GPN.

“…[ 105 ] More frequently, Chiari-I malformation causes glossopharyngeal neuralgia. [ 106 ] Chiari-I malformation may also compromise the vagal nerve. Chiari-I malformation may lead to compression of the LCN between the PICA and the herniated cerebellar tonsil.…”

Lesions of the lower cranial nerves (LCN) are due to numerous causes, which need to be differentiated to optimize management and outcome. This review aims at summarizing and discussing diseases affecting LCN. Review of publications dealing with disorders of the LCN in humans. Affection of multiple LCN is much more frequent than the affection of a single LCN. LCN may be affected solely or together with more proximal cranial nerves, with central nervous system disease, or with nonneurological disorders. LCN lesions have to be suspected if there are typical symptoms or signs attributable to a LCN. Causes of LCN lesions can be classified as genetic, vascular, traumatic, iatrogenic, infectious, immunologic, metabolic, nutritional, degenerative, or neoplastic. Treatment of LCN lesions depends on the underlying cause. An effective treatment is available in the majority of the cases, but a prerequisite for complete recovery is the prompt and correct diagnosis. LCN lesions need to be considered in case of disturbed speech, swallowing, coughing, deglutition, sensory functions, taste, or autonomic functions, neuralgic pain, dysphagia, head, pharyngeal, or neck pain, cardiac or gastrointestinal compromise, or weakness of the trapezius, sternocleidomastoid, or the tongue muscles. To correctly assess manifestations of LCN lesions, precise knowledge of the anatomy and physiology of the area is required.
