[Painful bilateral lumbar radiculoplexopathy associated with Epstein-Barr virus infection].

We report a case of polyneuropathy caused by primary Epstein Barr virus (EBV) infection in a 57-year-old patient. The primary EBV infection was confirmed by serology tests and EBNA (Epstein-Barr nuclear antigen) seroconversion. The main clinical sign was a highly painful subacute, bilateral lumbar radiculoplexopathy with amyotrophy which responded to corticosteroids and complement treatment within a few months. The association of left facial paralysis, neurophysiological signs of polyradiculopathy and elevated protein levels in the cerebrospinal fluid demonstrate the variability of peripheral neurological involvement in the same subject with EBV infection. This case also demonstrates the poorly limits of dysimmune polyneuropathies, including lumbar radiculoplexopathy which can be considered as an exceptional variant.

[Computerized tomography in the detection of metastatic cervical lymph nodes].

The accuracy of computed tomography (CT) in detecting cervical lymph node metastases was studied. Twenty patients with squamous carcinoma of the head and neck were selected. The results obtained by cervical palpation, CT and postoperative histological study were compared. Palpation had a sensitivity of 64% and specificity of 100%. CT had a sensitivity of 71% and specificity of 100%. The small gain in sensitivity does not justify the systematic use of CT to study cervical lymph nodes in head and neck squamous carcinoma.

[Painful shoulder syndrome with drooping after cervical lymphatic dissection].

A study was made of 12 patients with head and neck cancer who underwent surgical neck dissection in 1993 to evaluate quantitatively the degree of postoperative shoulder dysfunction after surgical neck dissection. Nerve conduction studies were made of the accessory nerve and the range of motion, strength and position of the shoulder were evaluated. Patients were invited to complete a questionnaire about daily living activities, shoulder pain, shoulder movement and shoulder droop. Our results showed that abnormalities can be found in shoulder and arm function after any type of neck dissection and that these are evident when the accessory nerve is damaged. Subjective questionnaire findings generally coincided with objective postoperative dysfunction.

[Laryngeal mucociliary clearance: influence of beta-2 agonists, beta antagonists, and alpha-agonists. An experimental study in rabbits].

Laryngeal mucociliary clearance was studied in 35 rabbit larynxes in the immediate post mortem period using charcoal powder. Mucociliary currents flowed from the subglottic walls to the posterior commissure. The normal laryngeal mucociliary clearance rate was 3.7 +/- 1.1 mm/min. Salbutamol accelerated mucociliary clearance (p < 0.01). Propranolol significantly reduced the mucociliary clearance rate (p < 0.001). Mucociliary clearance was not observed in any methoxamine-treated larynxes.

[Role of nasosinusal endoscopic surgery in the treatment of headache and facial pain of rhinogenic origin].

Headaches and facial pain are common complaints. In many cases patients are referred to an otolaryngologist to determine if head pain is sinus related. In the absence of other nasal or sinus symptoms, some rhinogenic headaches can be overlooked or misdiagnosed. A complete history and thorough ENT examination, including nasal endoscopy, with or without coronal CT scans, is the key to the correct diagnosis. Subtle exploratory findings such as minimal inflammatory changes or anatomic abnormalities of the ostiomeatal complex area may cause pressure resulting in facial pain. When medical treatment fails to produce sustained relief, surgery may be considered. Current worldwide thinking firmly supports the endoscopic endonasal approach as a safe and effective form of treatment in patients with nasal and sinus disease. We prospectively assessed 67 patients who underwent FESS for rhinogenic facial pain in the absence of other nasal or sinusal symptoms. The overall success rate was 93%. Only 5.9% of our cases had some minor complications. No major complications occurred.
