Abstract
In elderly patients, dizziness occurs very frequently with significant effects on the patient's life. Its frequency increases with age, and may arise from a variety of causes. Chronic dysequilibrium in elderly patients is most probably related to disturbances within the central nervous system, due either to altered neuronal functions or to an underlying vascular disease. Nicergoline, a drug used in the treatment of cognitive disturbances in geriatric patients, improves dizziness in elderly demented and non-demented patients. In a double blind,placebo controlled trial the drug improved (i) the severity of symptoms, measured by the dizziness assessment rating scale (DARS), (ii) the overall clinical conditions revealed by global impression scale, and (iii) the perceived quality of life estimated by the dizziness handicap inventory (DHI). These results indicate a possible positive effect also on posturographic measures. Moreover, the improvement occurred at no expense of the established strategy of postural control suggesting that the effect is mediated by a substitute compensatory mechanism allowing the patient to preserve consolidated postural strategies. The results of previous open clinical studies in about 3000 patients are in agreement with those findings. Overall, severity of symptoms decreased by 68 % (57 % in the control study). Globally, the results indicate a beneficial effect of nicergoline on symptoms related to balance disorders of central origin. Animal studies show that the drug displays a broad spectrum of actions on cellular and molecular mechanisms. Moreover, animal research specifically aimed at vestibular pathophysiology has revealed that nicergoline improves vestibular compensation in models of vestibular lesion. Chronic treatment with nicergoline improved the time-course of behavioral recovery in old rats after hemi-labyrinthectomy and counteracted the regulation of cholinergic receptors observed after lesion in old rats. Nicergoline interacts at several levels by various mechanisms, from the molecular level to cognitive function, probably enhancing spontaneous plasticity phenomena underlying the central vestibular compensation. This effect is not dependent from the interaction with a single-transmitter-identified neural pathway, but from anatomical, functional and neurochemical synergistic adjustments in several brain areas.

Abstract
Patients with squamous cell carcinoma of the head and neck (HNSCC) after being treated radically remain at high risk for both recurrent and second primary tumours. 13-cis retinoic acid (13-cRA) was demonstrated to reverse pre-malignant lesions of the oral cavity and to reduce the incidence of second primary tumours in patients treated radically for HNSCC. Synergism between retinoids and interferon in tumoural cell lines have been demonstrated. Based on these data, the Italian Head and Neck Chemoprevention Study Group started a randomized chemoprevention study in patients radically treated for stage III and IV HNSCC. From February 1992 to January 1996, 267 patients were randomized: 126 were allocated to the control group, 126 were randomized to receive 13-cRA at a dose of 0.5 mg/kg per day per os and 15 patients have been assigned to the group of 13-cRA plus interferon alpha2a (IFN-alpha2a) at a dose of 3,000,000 UI 3 times a week (randomization in this arm interrupted due to administrative financial problems). The mean follow-up was 39 months. The 5-year actuarial survival was 58.9% for patients of the 13-cRA group and 57.2% for those of the control group (P=0.94). Among evaluable patients, disease progression was observed in 45 of 123 patients (36.6%) of the 13-cRA group and in 42 of 124 (33.9%) of the control group. The 5-year actuarial relapse-free survival was 48.9% for the 13-cRA group and 55.6% for the control group (P=0.62). Adverse effects, mostly of grade I were reported in 69.4% of treated patients (haematologic disorders, mucositis, conjunctivitis, cutaneous toxicity, hypertriglyceridemia and hypercholesterolemia). Only 5 patients (4.1%) reported grade III-IV toxicity. Low-dose of 13-cRA given for 1 year is ineffective as chemoprevention in patients with radically treated HNSCC.

Abstract
AIMS To detail on sequential biopsies the morphological and immunohistochemical features of a case of primary lymph nodal fibroblastic reticulum cell (FBRC) tumour which progressed into a clinically aggressive cytokeratin-positive interstitial reticulum cell (CIRC) sarcoma. METHODS AND RESULTS A 70-year-old female underwent surgical excision of an enlarged submandibular lymph node. The nodal architecture was effaced by a neoplastic proliferation of medium to large cells, round to oval to spindle in shape, growing in a storiform pattern. The tumour stained for vimentin, CD68, factor XIIIa, alpha1-antitrypsin, fascin and actin. Dendritic and endothelial cell markers were negative. A diagnosis of FBRC tumour was made by combining pathological and clinical data. The patient received no therapy but 5 months later the tumour relapsed, exhibiting a deceptively pleomorphic cytology, phenotypic changes (strong cytokeratin positivity), intense p53 expression and aggressive clinical course with fatal outcome. In-situ hybridization for Epstein-Barr virus was negative. CONCLUSIONS We speculate that the morphological changes and p53 expression of the relapsing neoplasm might reflect tumour cell dedifferentiation, in keeping with the aggressive clinical course. The intense p53 expression suggests that this oncoprotein might also play a role in reticulum cell tumorigenesis.

Abstract
This study was aimed at evaluating the efficacy of beta-carotene in improving survival (S) and in disease-free survival (DFS) and reducing the incidence of second primary tumors (SPT) in patients with a radically treated stage I-II squamous head and neck tumors. Eligible patients were randomly allocated to receive beta-carotene (n=104) or no treatment (n=110). beta-carotene was administered at the dose of 75 mg/day for 3-month cycles within one month intercycle intervals for a 3-year period. The 3-year compliance to the beta-carotene was 68.7%. Only eight patients reported drug-related toxicity (7.8%). The median follow-up of all patients was 59 months. The median follow-up was 61 months (range 1-116 months) in the beta-carotene and 58 months (1-123 months) in the control group. The 10-year DFS was 75.7% for the patients in the beta-carotene and 74.3% for those in the control group (P=0.56). The 10-year S was 85.9% in the beta-carotene group and 80.9% in the control group (P=0.20). beta-carotene supplementation had no significant effect on the incidence of second primary tumors (RR=0.99; 95% C.I. 0.28-3.44). A statistically non-significant 40% reduction in the risk of death among subjects assigned to the beta-carotene compared to the controls was observed (RR=0.60; 95% C.I. 0.26-1.38). No increase in the death from cardiovascular diseases was observed among patients treated with beta-carotene. Our results might support the hypothesis that an adequate beta-carotene treatment could be potentially associated with a decreased risk of death in these patients.

Abstract
Angioneurotic edema is a non-pitting edema which is usually limited to the skin and the mucous membranes of the face and upper aerodigestive tract. The risk of acute upper airway obstruction makes angioneurotic edema a concern for emergency room physicians, internists and otolaryngologists because prompt recognition of the condition and immediate institution of therapy is essential for proper airway management. Angiotensin-converting enzyme (ACE) inhibitors have recently been associated with angioneurotic edema, the probable link being the reduction in angiotensin II and the potentiation of bradykinin, resulting in vasodilatation, increased vascular permeability and angioedema. We report four cases of acquired angioneurotic edema, which were probably related to ACE inhibitor use. These cases are discussed, including a review of the literature, methods of diagnosis, pathophysiology and treatment of angioedema. Care should be taken when antihypertensive ACE inhibitor treatments are started and patients should be warned of the potential risk of angioneurotic edema.

Abstract
Primary atrophic rhinitis is a chronic inflammation of the nasal mucosa characterized by atrophy of the mucous and bony tissue of the turbinates and by a thick, dense secretion, which quickly forms a characteristically fetid-smelling, greenish crust. We report the results of the clinical, genetic and immunologic investigations performed on eight subjects (three with ozena and five asymptomatic), members of the same familial group. The presence of the disease in the family fits well with dominant inheritance. All the culture specimens from the patients affected by ozena were positive for Klebsiella ozaenae, and one of them was also positive for Pseudomonas aeruginosa. All the three patients with ozena and two of the five apparently unaffected family members were positive for antinuclear antibodies. Immunoblotting showed a reactivity to a 50-kD protein, which was not identified by the common, recognized nuclear autoantigens. This was present in one of the three patients and three of the five other family members. Positivity for IgG-class anticardiolipins was correlated with disease manifestation in that it was found in two of the three patients and only in one of the five asymptomatic family members. The hypothesis of a genetic factor that could drive the chronicity of the inflammatory pattern of a pre-existing infectious nasal disease is suggested.

Abstract
Haemangiopericytomas are vascular tumours derived from Zimmerman's pericytes; they account for about 1% of all vascular tumours. About 5% of the cases occur in the nasal cavity and usually show well-differentiated tumours with low potential for local recurrence or metastasis. The treatment of choice is surgical resection. We present a case of nasal haemangiopericytoma treated by endoscopic resection, and we emphasise the advantages of this minimally invasive method compared with traditional methods.

Abstract
Leakage around the prosthesis is one of the worst problems afflicting patients fitted with tracheoesophageal (TE) voice prosthesis. Removing the prosthesis for a few days can reduce the size of the fistula, or the leakage may be eliminated simply by replacing the prosthesis. In cases that are refractory to such treatment, the perifistular injection of different types of autologous, heterologous or alloplastic substances has been proposed. A new kind of silicone, previously available abroad, has recently appeared on the Italian market as well; constituted by polydimethylsiloxane textured elastomers (Bioplastique) for soft tissue implants, it appears to guarantee excellent standards of long-term safety and stability. Three patients fitted with Provox2 tracheoesophageal voice protheses who had been experiencing leakage for about 4 months underwent Bioplastique implant procedures. The correction of the fistula size was easy to accomplish and well tolerated by the patients. There was no sign of inflammation, formation of granulomas or other pathological modifications, and the size of the fistula, together with its fluid-tightness, remained stable in time. From our point of view, the Bioplastique implant appears to provide valid and effective treatment of gaping TE fistulas.

Abstract
OBJECTIVE The purpose of this study was to evaluate the efficacy of selective neck dissection (SND) for elective treatment of the clinically negative neck in head and neck squamous cell carcinoma (SCC). METHODS A retrospective review was undertaken on 91 previously untreated patients with T1-4 SCC of oral cavity (23), oropharynx (5), hypopharynx (7), larynx (56), and clinically negative neck (N0), undergoing 126 SND from January 1990 to March 1999 at a single institution. Twenty-five patients received postoperative radiation therapy on the basis of histologic evidence of >2 positive nodes, extracapsular spread (ECS), and/or the presence of advanced primary lesion. RESULTS On pathologic examination the average number of lymph nodes was 20.5 per neck, occult disease was detected in 14 (11.11%) of 126 necks; of necks with positive nodes, 6 (42.85%) of 14 had ECS. The median follow-up was 36 months. Overall recurrence rate (local, regional, and distant) was 12.8% (11 of 91). Recurrent disease developed in the neck of one patient, outside the dissected field. There was no difference in recurrence rate between pN0 and pN+ patients, as well as between pN+ with or without ECS. Overall survival rate was 84% (77 of 91), with a statistically significant difference between pN0 and pN+ necks. CONCLUSION SND seems to be a pragmatic approach that is as effective as comprehensive procedures for staging and treating the clinically negative neck.

Abstract
BACKGROUND Surgical treatment of hypopharyngeal cancers with extension to the retrocricoid region generally requires a circumferential pharyngolaryngectomy followed by a reconstruction of the removed segment of the upper digestive tract. Historically, many techniques have been used in order to achieve a safe and functional reconstruction. Jejunum interposition is generally considered the best reconstructive technique. METHODS This study examines the details of the surgical technique, the complications, the oncological and the functional results in a series of 29 consecutive patients submitted to circumferential pharyngoesophageal resection for advanced hypopharyngeal cancer followed by reconstruction with a free flap of jejunum. RESULTS Three of the transplants failed because of venous thrombosis. The overall success rate was 90%. There were no general complications. A good swallowing has been preserved in all our patients. All our patients where a phonatory prosthesis was positioned (20/29) were able to achieve speech following speech therapy and all were satisfied with their own capacity to communicate. CONCLUSIONS The prognosis of hypopharyngeal tumours (18-40% at 5 years) remains poor, but jejunum autografts are being shown to be an excellent choice for the reconstruction of the cervical hypopharyngo-oesophagus offering the patient fast rehabilitation and a reasonable quality of survival. Our experience confirm that this kind of reconstruction is safe with a good results in improving oncologic controls and restoring a good quality of life.

Abstract
This multicenter, randomized open-label study compared the efficacy and safety of roxithromycin tablets 300 mg once a day (Rx) and amoxicillin/clavulanic acid tablets 875+125 mg twice a day (Acx), administered for a mean of 7 days. The study was carried out in five centers on 100 in- or out-patients of both sexes, aged between 18 and 91 years (mean 38+/-14). All patients suffered from ENT diseases, 85% with acute otitis media, 31% pharyngotonsillitis and 11% rhinosinusitis. The patients were divided into two randomized groups of 50 patients each. Clinical evaluations (signs and symptoms) were performed before, during and at the end of therapy. At the end of therapy, for intent-to-treat and per-protocol populations, a satisfactory overall clinical response was achieved by 82% of patients in the Rx group and 78% in the Acx group with similar reductions in signs and symptoms of disease in both groups. Safety was good, with only 2 patients of the Rx group and 4 patients of the Acx group presenting side effects, involving mainly the gastrointestinal system. Rx appears to be active and safe in the therapy of ENT diseases exhibiting similar effects on the reduction of signs and symptoms as Amx but with better compliance because of once-a-day administration.

Abstract
Speech restoration after circumferential pharyngolaryngectomy with free jejunal repair for advanced tumors of the hypopharyngo-esophageal tract remains a difficult problem to solve. We report here the results of secondary voice restoration in six patients who received a Provox 2 type prosthesis and intensive speech therapy after circumferential pharyngolaryngectomy with free jejunum repair. No patient had operative or post-operative complications due to insertion of the prosthesis. No patient had to have the prosthesis removed during the follow-up (8 to 14 months). Analysis of some acoustic parameters of voice (fundamental frequency, waveform perturbations) and qualitative characteristics of speech (intelligibility, pleasantness and acceptability) demonstrated that all the patients were able to produce satisfactory speech after tracheojejunum puncture and speech therapy and were satisfied with their own ability to communicate. Our results are reassuring and we therefore advise that in patients undergoing free jejunum flap reconstruction of the hypopharyngo-esophageal tract voice restoration should be attempted by placing a voice prosthesis through a secondary tracheo-esophageal puncture and providing intensive speech training.

Abstract
In the authors' series of 12 consecutive patients who had oral reconstruction using the indications described above, flap survival always was achieved. Venous congestion was observed often: the flap became intensively red, showing a disappointing color that resolved spontaneously with only skin de-epithelialization. In one case of floor-of-the-mouth repair, a marginal necrosis of the distal portion of the flap occurred, possibly because of a venous drainage problem. The secondary defect healed spontaneously, without fistula formation. The time required to outline the flap is less than for most other flaps, and donor site morbidity is minimal. In selected cases, a platysma flap is an easy and rewarding solution for repairing various oral defects.

Abstract
To evaluate the feasibility, maximum dose of drug tolerated, technical problems, systemic and local toxicity, response rate, overall and disease-free survival, we studied superselective intra-arterial infusion of high-dose carboplatin as part of a multimodality treatment for head and neck cancer. Forty patients with untreated stage II-IV head and neck squamous cell carcinomas received induction chemotherapy with high-dose carboplatin (three cycles at 2-week intervals using 300-350 mg/m2 per cycle), delivered via superselective transfemoral angiography followed by radiotherapy or surgery plus radiotherapy. No technical complications occurred during or after the infusion. Systemic toxicity was minimal, and local toxicity was moderate. At the end of chemotherapy the overall complete and partial response rate was 90% (36/40) at the primary site and 64% (16/25) at the neck nodes. The median follow-up was 24.4 months (range 3-52). To date 21 patients are alive without disease, 2 are alive with disease, 13 have died of disease, and 4 have developed a metachronous lung tumor. There was a good correlation between the response to chemotherapy and disease-free survival. No statistically significant benefit in survival was observed with respect to other series of head and neck tumors treated with different protocols. However, discriminating between responding and nonresponding patients, this procedure can have a prognostic significance in planning integrated treatments for these types of tumors.

Abstract
Papillary carcinoma in thyroglossal duct remnants is a rare and usually unexpected finding. It is controversial whether or not prophylactic thyroid gland dissection is necessary in such circumstances. We present our experience of four cases. Based on this, a consideration of published risk factors, and evaluation of the likelihood of a primary versus metastatic origin of the malignancy, we present a therapeutic decision procedure. When the thyroid is normal, the patient presents low-risk factors for thyroid cancer, and there is evidence that the malignancy is primary, removal of all thyroglossal duct remnants by the Sistrunk procedure is sufficient.

This operation consists of drawing the stomach or part of it up through the chest and mediastinic region to the neck where a mucosal anastomosis with the residual pharyngeal tract is made. The most feared complication is proximal necrosis of the gastric stump with salivary fistulae usually followed by a mediastinitis. In the presence of such a complication the surgeon must tackle the challenge of reconstructing the missing part of the intrathoracic digestive tract. We describe the case of a patient in whom the missing intrathoracic oesophagus, following complete necrosis of a previously performed pharyngogastroplasty, was reconstructed using a revascularized lateral thigh free flap.

Abstract
BACKGROUND AND OBJECTIVES Oropharyngeal carcinoma tends to be aggressive and deeply infiltrative of nearby sites, with an high incidence of lymph node metastases. The last treatment decision generally depends on the stage of the lesion and the patient's general status. Oropharyngeal tumor is generally treated by integrated treatments. METHODS We retrospectively studied 115 patients with locally advanced oropharyngeal tumors treated in our institution with combined therapies compare the results in two different groups of patients (surgery plus radiotherapy and chemotherapy plus radiotherapy). RESULTS The 3-year overall survival rate in patients who underwent surgery plus radiotherapy was 82% and in those who underwent chemotherapy plus radiotherapy was 49%. CONCLUSION The results suggest that surgery followed by radiotherapy seems to be the best treatment in the case of locally advanced oropharyngeal tumor.

Abstract
The aggressiveness of hypopharyngeal cancer makes broad resectioning of the circular pharyngolaryngoesophageal segments necessary, followed by reconstruction to restore the anatomical gap created as fully as possibly creating a neoesophagus with thin walls that can easily be released. Over the years several procedures have been fine tuned for reconstruction of the upper digestive tract employing transposed viscera, miocutaneous pedunculated flaps, revascularized fascio-cutaneous or visceral free flaps. Currently the revascularized jejunum loop is one of the most commonly used methods in the reconstruction of the hypopharynx. Its popularity is due to some anatomical and physiological advantages: it requires transposition of a brief intestinal tract anatomically well adapted to the reconstruction site, ensuring rapid functional recovery. The authors report the oncological and functional results obtained in 25 patients who underwent circular pharyngolaryngectomy followed by reconstruction with a revascularized jejunum loop. The percentage of transplant survival was 90% and local and general complications were reduced to a minimum. The functional results--both in terms of deglutition and phonation--were satisfactory while patient survival (6-37 months follow-up) was in line with that reported by other authors for the same tumor (47%). Although prognosis for hypopharyngeal-esophageal neoplasms is still quite poor, this experience shows that circular pharyngolaryngectomy followed by reconstruction with autotransplant of the jejunum is an excellent choice since it offers the patient a prompt, acceptable functional recovery and a fair quality for his remaining life.

Abstract
In recent years there has been a marked increase in mycosis infections of the paranasal sinuses, attributed both to an increase in the survival of subjects at risk and improved diagnostic techniques (endoscopy, CT, MR) able to identify cases which had previously gone unrecognized and treated as aspecific chronic sinusitis. The present study involves 45 cases (4.3%) out of a total of 1050 patients who had undergone endoscopic surgery for sinusopathy between April 1994 and December 1998. Following the Katzenstein classification, the cases were broken down into non-invasive chronic mycoses or fungus ball (34 cases), allergic mycoses (7), chronic indolent invasive mycoses (3) and fulminating invasive mycosis (1 case). The mycetes most often involved was Aspergillus Fumigatus (76.9%). The recurrent symptom was facial algia, followed by nasal obstruction. Paranasal sinuses endoscopy did not modify the specific picture. CT presented such indicative signs as focal areas with non-homogeneous intensity, images of metal-like foreign bodies and endosinus calcifications in 84.4% of the cases. MR--performed in only 6 cases--always presented T2 images showing the typical signal void area corresponding to pathological lesions. All patients underwent endoscopic surgery of the paranasal sinus. The effectiveness of this treatment differed according to the clinical form. In the fungus balls surgery always resolved the pathology without requiring subsequent pharmacological treatment. In allergic mycosis, surgery improved the symptom of nasal respiratory obstruction but local drug treatment was required. With the aid of drug treatment, surgery resolved chronic indolent invasive mycoses and prevented the endocranial progression of complications. In the cases of fulminating invasive mycosis, timely surgery prevented the onset of endocranial complications and made it possible to perform antimycotic polychemotherapy to control the disease. This experience shows how important a protocol involving several different tests is in diagnosing the many clinical forms of paranasal sinus mycoses and distinguishing them from sinusopathies. Endoscopic surgery is indicated for all forms of paranasal sinus mycoses although the realistic objectives differ according to type.

Abstract
The purpose of rhinosinus revision through endoscopic surgery is to resolve recurrent, residual pathologies in patients with drug-resistant symptoms and to prevent ocular and endocranial complications. Surgical revision proves quite complex because of the destruction of the anatomical structures. More over the presence of tougher scare tissue which bleeds easily increases the risk of iatrogenous complications. Axial and coronal-projection tomography without contrast medium must be performed prior to surgery. Endonasal orientation is ensured by six main reference points. Three of these points--nasal septum, upper edge of the choana and upper edge of the nasolacrymal duct--are nearly always present while the others may or may not be, depending on what sort surgery has been performed. The present work gives the guidelines for a correct approach to patients who have undergone many previous procedures.

Abstract
OBJECTIVE To investigate the capacity of helical CT in the pre- and post-operative management of oromandibular reconstruction of patients with oropharyngeal carcinoma using microvascular composite free flaps. MATERIALS/METHODS Thirty-four patients with oropharyngeal cancer were examined by helical CT and nine (six men and three women) submitted to oromandibular reconstruction. The osteomyocutaneous flaps used for reconstruction were taken from the iliac crest in six cases and from the fibula in three cases. All patients were examined by CT 1 - 4 days postoperatively and then at 6 monthly intervals. Double helical scans were performed in all cases, with slices of 2 - 3 mm for primary lesion studies and 5 mm for lymph node staging, pitch >/=1 and RI=1. Multiplanar (MPR) and 3D reconstructions were obtained from pre- and postoperative CT examinations. RESULTS Preoperative CT showed massive bone infiltration in six of the nine surgical patients and marginal infiltration in three. These findings were confirmed histologically. There were no false negatives. The immediate postoperative examination showed correct flap positioning in eight of nine cases. The flap underwent ischemic necrosis in two cases; CT showed very early signs of bone ischemia in both. CT detected two cases of recurrence after about 1 year. CONCLUSIONS Axial CT permitted adequate assessment of the extent of mandibular infiltration and detected early ischemic complications and distant recurrences. Integration with MPR and 3D reconstructions simplified the choice of flap type and size and enabled the postoperative assessment of correct flap positioning. This helped the surgeon plan subsequent rehabilitation with osseo-integrated implants.
