Persistent Postural-Perceptual Dizziness (PPPD) is a chronic functional disorder that manifests with symptoms of dizziness, unsteadiness or non-spinning vertigo that lasts for at least three months. These symptoms are exacerbated by upright posture, active or passive motion, and exposure to complex or moving visual stimuli. This -pathology has been known for a long time ago. Still, after an expert's consensus in 2017, this term was born, and some precise diagnostic criteria have been defined based on identifying key symptoms in the patient's clinical history. Treatment is multimodal, incorporating -vestibular rehabilitation, cognitive-behavior therapy, and serotonergic medication.

Plasmocytomas are either medullary (disseminated form) or extramedullary with or without bone infiltration (located form). Plasmocytoma is not a common tumor but extramedullary forms mostly occur in the upper respiratory tract without specific manifestations.The aim of this study is to discuss the management (diagnostic and therapeutic) and the follow-up of extramedullary nasal plasmocytoma.We report a case of a 71-year-old patient with unilateral nasal obstruction manifestation.Endonasal biopsy concluded plasma cell tumor without extension on CT scan. Treatment consisted of external nasal surgery and radiotherapy.Diagnosis of solitary extramedullary plasmocytoma can only be confirmed when the presence of systemic disease is excluded by performing clinical, biological (marrow bone biopsy) and radiological investigations. The treatment should be based on surgery with complementary radiotherapy if there is a skull base erosion. Long term follow-up is necessary because of the high risk of diffuse marrow involvement (multiple myeloma) which may occur after a long delay.

The authors report their experience in a retrospective study of 28 patients with symptomatic hypopharyngeal diverticulum.The mean age was 70 years. Eight patients presented with severe dysphagia and nine with weight's loss. The delay before diagnosis was 17 months. All patients included were studied by an oesophageal barium swallow prior to any treatment. According to Van Overbeeck's classification, diverticula were medium sized in 11 patients, small in 8 and large in 7. All patients had endoscopic assessment of the diverticular pouch; 26 patients were treated by microendoscopic laser myotomy and 2 by resection.The average time for oral feeding was 4 days. None of the 28 cases had a postoperative complication. 25 patients had partial or complete relief of symptoms after their initial treatment. In 3 cases recurrence of symptoms occurred, of whom 2 underwent endoscopic revision and 1 underwent an open procedure.Endoscopic laser surgery for Zenker's diverticulum can be recommended as the treatment of choice for elderly patients. It is a useful procedure because it is swift, effective with a low rate of morbidity, even in cases with impaired of health or associated diseases.
