[Pansinusitis: approach to its etiopathogenesis].

Local factors and external conditions are determinants for pansinusitis. We present 10 cases in which 20% are of unknown origin, 30% have allergic antecedents, 20% show hypersensitivity to aspirin, 20% have an immotile-cilia syndrome and 10% are caused by exogenous factors. Surgical treatment is performed in 70% of the cases, always followed by a long-term medical therapy. Forty per cent of the cases show a chronic progress despite the type of treatment applied.

[The histological study of adenopathies in laryngeal cancer with supraglottic localization].

A histopathologic study was made to establish the prognostic importance of lymph node involvement in operable supraglottic laryngeal carcinoma. A total of 51 cancer patients underwent supraglottic horizontal laryngectomy with bilateral cervical dissection. The number of adenopathies the presence of capsule rupture and type of corresponding infiltration were significantly related to survival (p < 0.01). Prognosis was poorer in patients with more than three metastatic adenopathies and/or capsule rupture of one or more of them. Patient survival in cases with capsule rupture affecting one or more nodes was 36%, versus 33% among patients with three or more metastatic nodes. It is concluded that (a) the poor survival rate observed among these patients points to the need for more aggressive treatment protocols; and (b) cervical dissection should be performed systematically not only for therapeutic purposes but also to improve patient prognosis.

[The effect of visual feedback exercises on balance in normal subjects].

The effects of visual feedback exercises on balance was studied in normal individuals, to evaluate the efficacy of visual feedback of postural oscillation in improving stability. A DINAS-CAN dynamometric platform designed by the Valencian Institute of Biomechanics (IBv) was used. Before to commencing training sessions, we determined the following parameters in each individual: (a) static stability, via posturography; and (b) individual ability to displace and voluntarily maintain the center of gravity within the limits of stability. All static measures were poorer after training, but the differences were not significant (p > 0.01). In contrast, the exercises performed via visual feedback of postural control improved significantly (p < 0.01). Training by visual feedback facilitates integration of visual, somatosensory, and vestibular information. In normal individuals, stability improves under excentric conditions, but no improvement is seen in the central resting position.

[Verifiable diagnosis of the puncture of the fine needle aspiration in head and neck neoplasms].

We have studied 103 fine needle aspiration (FNA) biopsies as diagnostic technique on patients with head and neck tumours: 55 FNA on thyroid gland, 35 in cervical lymph nodes and 13 on salivary glands. The results obtained by PAAF were coincident in 90.8% of the cases with histology and clinical evolution of the patient. Specificity was of 98%, sensibility to detect the tumour presence 84%, with a positive predictive value of 95%. No complications were found in any of the patients. We conclude that PAAF is an excellent first line method for diagnostic investigation of palpable masses in head and neck, and allows us to reduced the number of surgical manoeuvres.

[Primary ciliary dyskinesia: functional and morphological study].

We present 7 patients with a typical symptomatology of immotile cilia syndrome, three of them with complete situs inversus. Nasal mucociliary transport was studied by sero-albumin marked with technetium 99m. In all cases there was an absence of transport. The ultrastructure of the nasal cilia was studied. The findings were: In four cases alterations in the dynein arms, in three cases alterations in the central and peripheral microtubules associated por not to the defects in the dynein arms, and in one cases absence of cilia were observed. The ciliary complexes were common to all cases.

[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.

[Clinical and ultrastructural evaluation of nasal mucociliary function in HIV-positive patients. Preliminary investigation].

Nasal mucociliary transport was studied in 33 HIV-positive patients with different stages of infection. Ciliary ultrastructure was studied in 8 of these cases. At the time of study, 24 patients had respiratory infections. Disturbances in mucociliary transport were found in 25 cases. In 6 of the 8 studies of ciliary ultrastructure, changes in the ciliary axonema were found, particularly in the central and peripheral microtubules.

[Incomplete ciliary axonema: anther cause of ciliary dysmotility syndrome?].

Immotile cilia syndrome is associated with different ciliary defects, although the clinical presentation is similar in every case. A study was made of a 36-year-old woman with recurrent respiratory infections since birth, chronic sinusitis and chronic bronchitis with bronchiectasias. Her medical history included a tubaric pregnancy and two miscarriages. Nasal mucociliary transport was investigated on two occasions at a 1-year interval using an isotopic technique. Ciliary ultrastructure was studied by electron microscopy after obtaining two biopsies from the inferior and middle turbinates separated by a 1-year interval. The sweat test and blood immunoglobulins were normal. The absence of mucociliary transport was verified on both occasions. An abnormality was observed in 30% of the cilia in the form of semicircular ciliary cross-sections, with only 7 pairs of peripheral microtubules. The central pair was normal. We termed this anomaly "incomplete ciliary axonema" and believe that it could be another cause of immotile cilia syndrome.

[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.
