ABSTRACT

OBJECTIVE/METHODS: An exhaustive review of literature was performed to investigate available data and evidences regarding pediatric otolaryngologic manifestations of viral systemic infections. RESULTS/CONCLUSIONS: Modern otolaryngologists should be familiar with viral systemic infections since many have head and neck manifestations. Cooperation between otolaryngologist, paediatrician and virologist can be considered and excellent tool in diagnosis and treatment of these diseases in particular when complications occur.

ABSTRACT

Indications to surgery for adeno-tonsillar inflammatory disorders and analysis of the effectiveness of surgical treatment, compared with watchful waiting strategy, continue to be the subject of scientific debate. The present investigation focuses on the surgical activity of 14 Italian Otorhinolaryngological Units between 1999 and 2004. Surgical interventions (adeno-tonsillectomy, adenoidectomy, tonsillectomy) on 26915 children (age range: 2-11 years) were considered. Data on adeno-tonsillar interventions were analysed in relation to other interventions of ENT interest, performed in the same units and in the same period. Adeno-tonsillar interventions accounted for 35.4% of all operations of ENT interest. Adeno-tonsillectomy accounted for 56.6% of overall adeno-tonsillar operations, adenoidectomy 31.6%, tonsillectomy 11.8%. The percentage for the three interventions was homogeneous in the period of the study and in the recruited units. The percentage of children who underwent adeno-tonsillar surgery in paediatric units was higher as compared to general units, as far as concerns the overall number of operations performed. In southern Italy, the number of adeno-tonsillar interventions, in general, and of adeno-tonsillectomy, in particular, was higher compared to that in northern Italy. Results of the present study suggest that environmental factors, cultural issues and local health demands, may influence indications and, therefore, the different incidence of the operations under consideration in the units taking part in the investigation.

ABSTRACT

There are many reports concerning the morphology of hairy cell leukemia (HCL), but, to our knowledge, there are no data on the ultrastructural modifications of HCL during interferon therapy. The ultrastructural modifications of neoplastic cells in peripheral blood in a case of HCL were investigated before and 2 and 4 months after beginning treatment with human lymphoblastoid alpha-interferon. Before therapy, hairy cells displayed the typical cytoplasmic projections, and 4% contained ribosome-lamellae complexes (RLC) (the cells contained up to 7 RLC). Two months from the beginning of therapy, hairy cells had shorter projections, RLC had disappeared, and tubuloreticular structures (TRS) had appeared in 2.2% of the elements. Four months from the beginning of therapy, TRS persisted in 2.3% of hairy cells, cylindrical confronting cisternae (CCC) appeared in 6.8% of the cells, and uncommon RLC, in close contact with the rough endoplasmic reticulum and nuclear membrane, were found in 1.5% of the elements. The cells contained up to 3 RLC. Our data confirm that interferon stimulates the synthesis of TRS and CCC, whereas the reappearance of uncommon forms of RLC could reflect their neosynthesis, possibly related to the interferon therapy. The frequent findings of a close contact between RLC and nuclear membrane support the view that RLC are derived not only from rough endoplasmic reticulum, but also from the nuclear membrane.

ABSTRACT

The Authors show their original technique for the differential diagnosis of cochlear and retrocochlear hearing loss which employs ipsilateral masking of the A.B.R. in order to define the difference in V wave latency between a standard technique (clicks at 21 pps without noise) and a sensitized technique (clicks at 21 pps with noise at S/N of +40). This difference in latency has been named Sensitizing Latency Difference (SLD). Sixty normal subjects, 85 patients with cochlear hearing loss and 6 with retrocochlear hearing loss, were studied. The obtained data showed a SLD value: in normal hearing of: a) 0.31 msec. (+/- 0.14 SD) from 18 to 40 years old; b) 0.36 msec. (+/- 0.26 SD) from 41 to 60 years old; c) 0.48 msec. (+/- 0.21 SD) over 60 years old; in patients with cochlear hearing loss 0.12 msec. (+/- 0.14 SD) in 2 subjects affected by retrocochlear hearing loss a value superior to 1.5 msec. in the other 4 cases the V waves disappeared during recording of the sensitized test. A differential value of 1 msec. between cochlear and retrocochlear hearing loss was established by the Authors who with this value correctly identified all the patients with retrocochlear hearing loss and 97.8% of the subjects with cochlear hearing loss. An incorrect diagnosis of the hearing loss origin (false positives) was made in 2.2% of the patients with cochlear hearing loss. In conclusion, the Authors feel that the SLD evaluation, in consideration of its large clinical utility and of the high reliability of obtained data, is a particularly useful test in making a differential diagnosis between cochlear and retrocochlear hearing loss.

ABSTRACT

The present work evaluates the results obtained in a group of 360 patients with laryngeal-glottic tumors (classification T1/T2-N0-M0) who, in the last 10 years, have undergone direct microlaryngoscopy surgery employing a CO2 Laser. In the T1 glottic carcinomas the neoplasm was limited to the vocal cord on one side or it involved the anterior commissure and, most likely, the vocal cord on the opposite side; in T2 glottic tumors the extension reached the hypoglottic region and/or the Morgagni ventricle and the false vocal cords on one or both sides but without compromising laryngeal motility. The five year healing rate for the T1 tumors proved to be 84.7% while it was 74% for the T2 forms. In 36 cases complications were found which can be broken down as follows: - limited local recurrences (13 patients) requiring subsequent direct microlaryngoscopy; - regional lymph node metastases (6 patients) without reproduction of the primary neoplasm; in general (5 of the 6 cases) these patients underwent lateral neck dissection; - spreading of the neoplastic process (17 cases) which made total laryngectomy with lateral neck dissection necessary; this procedure was performed in 15 cases. When these subsequent surgical procedures are also taken into account the percentage healing rises to 94.3% for T1 glottic tumors and to 84.9% for T2. Detailed analysis of the case study, comparison with the data found in the relative literature regarding patients treated with traditional techniques, a series of observations on the advantages and disadvantages inherent to the techniques employed have all led to the conclusion that the use of a CO2 laser in the treatment of laryngeal tumors gives excellent results in terms of prognosis. Moreover, this technique offers significant advantages over the traditional methods and constitutes a reliable technique for partial laryngectomies as long as the indications are accurately applied and the proper techniques used.

ABSTRACT

Fifty-one patients with systemic sclerosis (scleroderma) underwent videofluoroscopy during barium swallow to evaluate the incidence of oropharyngeal deglutition abnormalities and to correlate the radiologic patterns of esophageal motility abnormalities with patients' clinical features. Thirteen patients (26%) showed swallowing dysfunction, (e.g., oral leakage, retention, penetration, mild or moderate aspiration, and upper esophageal sphincter incoordination). These dysfunctions were more severe in patients with prominent esophageal dysmotility. Normal esophageal motility was not associated with swallowing alterations. Patients with an oropharyngeal disorder had a higher incidence of pulmonary disease. The clinical picture of the above-mentioned 13 patients was more severe, based on the duration of Raynaud's phenomenon and duration of skin sclerosis. Patients with primary Raynaud's phenomenon had no oral or esophageal abnormalities. The esophageal phase of swallowing was abnormal in 80% of the patients with scleroderma. Esophageal dysfunction, therefore, seems to be frequent in the early stages of the disease. However, patients with advanced or extensive disease may have normal esophageal function.

ABSTRACT

636 patients suffering from several laryngeal pathologies were treated with the CO2 laser. The results obtained confirm that this instrument is a valid alternative surgical tool, in comparison with the traditional surgery, because it allows to carry out the removal of the lesion with greater precision and more advantageously, when clinical indications are exact and surgical technique correctly performed. The results are as follows: Vocal nodules: no real advantages are offered by the CO2 laser in the treatment of these pathologies, whereas, in a small percentage of cases, the occurrence of reactive nodules or scars was noted; Cordal polyps are better removed with the traditional procedures, whereas the CO2 laser allows a more accurate excision of voluminous polyps or edemas of Reinke because of the bloodless operative field; Dyskeratoses: better functional results can be obtained using the laser. In these cases, however, an accurate preoperative evaluation is of fundamental importance to exclude any carcinomatous degeneration; Laryngeal amyloidosis is easily removed with minimal trauma and functional impairments using the laser; Laryngeal papillomatosis: the laser makes it possible to achieve complete recovery if radical excision, avoidance of accidental laryngeal damage and frequent postoperative controls are done; Laryngeal cancers: when clinical indications are correct, the main laser advantages in the treatment of T1 and T2 glottic cancers are the endoscopic removal of the lesion, avoidance of tracheotomy, shorter hospital stay and better quality of voice. Radical excision of the lesion is obtained by dissecting the tumor along the traditional cleavage plane, i.e. the inner perichondrium of the thyroid cartilage; Bilateral vocal cord paralysis: partial or total arytenoidectomy can be performed with the laser, with excellent functional results and minimal trauma and inconveniences; Laryngeal stenoses: chronic aditus edemas, vocal cord synechiae and webs are easily removed, taking care to avoid damage to the posterior commissure or to the elastic tracheal wall and performing frequent endoscopic removal of the fibrin clots in the postoperative period. Concentric stenoses and circumferential webs are firstly vaporized, then a silastic Montgomery T-tube is placed in the neocavity and left in place until re-epithelialization is completed. The insertion of a metallic tracheotomic cannula in the horizontal and descendant branches of the T-tube has been shown to be a useful precaution in order to achieve better results.
