The strict definition of Ramsay Hunt syndrome is peripheral facial nerve palsy accompanied by erythematous vesicular rash on the ear. We report a 57-year-old female immunocompetent patient complaining of otalgia, small vesicles on the Ramsey Hunt Zone. She does not complain fever, hearing loss, nausea, vomiting or dizziness. There was no peripheral facial nerve palsy, no reduction of taste sensation, no ataxia or nystagmus, Romberg sign was negative. Our patient targets two of the three criteria needed for the diagnosis of Ramsay Hunt syndrome. She began to take Acyclovir-Steroid (AS) therapy very early with good outcome. This suggests that prompt diagnosis and management improve outcome and prevent occurrence of nerve palsy in Ramsay Hunt syndrome.展开更多

The main tool of this paper is the spine decomposition and we only need an L log L condition.展开更多

In the beginning of the paper, we summarize the main results obtained so far for the problem. Then, we present two new necessary and sufficient conditions for the validity of （H）. Furthermore, we give applications of these new criteria. First, we give explicit constructions of Levy processes satisfying （H） in a context where previously known results could not be applied. Second, we show that a large class of pure jump subordinators can be decomposed into the summation of two independent subordinators such that both of them satisfy （H）.展开更多

Case Study: We report the case of a 32-year-old married female beautician patient admitted with severe right otalgia associated with a fever that had been evolving for three days. The addition of homolateral otorrhea and headache was noted. The initial examination on admission noted a vesicular rash of the pinna and the external third of the right external auditory canal with a normal tympanic membrane. The evolution was marked 48 hours later by the appearance of a right facial palsy grade V. The CT scan of the rock showed a mastoid and maxillary sinus hypodensity. The paraclinical exploration found a positive retroviral serology to HIV 1 and 2. The diagnosis retained was a Ramsay Hunt syndrome on HIV condition associated with ipsilateral maxillary sinusitis and mastoiditis. The treatment administered was a combination of amoxicillin/clavulanic acid injection of 3 g per day + oral aciclovir 200 mg, acetaminophen 1 g injectable every 6 h, betamethasone 4mg per day, vitamin B complex, artificial tear. Therapeutic inclusion in the HIV/AIDS national program was performed. The evolution was marked by the total regression of the facial palsy after six months of treatment. Conclusion: Otogenic diseases in HIV remain a problem in our context where the circumstances of discovery are most often fortuitous, hence the need to search for the serological status in front of any suspicion of viral infection in adults. The status may constitute a triggering factor or a factor of the severity of the pathology or of the symptoms such as facial palsy or deafness in our case. Early and adapted management has been shown to improve the prognosis.展开更多

These findings suggest that early physiotherapy improved the prognosis of patients with cerebral aneurysms who were treated by surgical clipping or endovascular embolization.Patients with a worse clinical status at presentation had a poorer functional status at discharge.The outcome of physiotherapy was not affected by whether surgical clipping or endovascular embolization was chosen for treatment of the aneurysm.展开更多
