RESUMO
The aim of this study is to present our management protocol of sphenopalatine artery bleeding, demonstrating that nasoendoscopic cautery (NC) was a more effective method than the nasal packing, in terms of shorter inpatient stay and reduced complications rate. We present ten posterior epistaxis not resolved by nasal packing. Tabotamp® was placed in the area of sphenopalatine foramen and/or in those parts of the posterior nasal cavity, where it was suspected that bleeding origins. In two cases, the bleeding was resolved in this way, instead eight cases needed of subperiosteal cauterization of sphenopalatine artery by Dessi bipolar forceps (MicroFrance®). 4 of these 8 patients evidenced a remarkable bleeding removing nasal packing (Hb before-nasal packing = 15 ± 0.69 versus Hb after-nasal packing = 13.3 ± 0.81; t student = 2.94; p value = 0.025). These four patients showed a deviation of the nasal septum ipsilateral to epistaxis, and according our experience, a traumatism of sphenopalatine area can be caused by Merocel® nasal packing in this condition. During follow-up, no recurrences of nasal bleeding have been observed in such patients. Nasal packing must be considered if posterior epistaxis is severe, but always taking into account the specific anatomy of patient and in particular septal spurs that can further compromise sphenopalatine artery. In our experience, the endoscopic endonasal cauterization of the sphenopalatine branches represented a safe and effective procedure.

OBJECTIVE: Recurrent respiratory papillomatosis (RRP) is characterized by exophytic, benign, and papillary lesions infected by the virus in the epithelium of the upper aerodigestive tract. RRP is caused by persistent infection of the respiratory epithelium by human papillomavirus (HPV) HPV6 and-11. The clinical course of RRP is unpredictable, frequently relapsing, and may be lifelong. The aim of this study is to evaluate the efficacy and safety of the use of intralesional Cidofovir in the treatment of RRP. PATIENTS AND METHODS: We have selected articles on the use of cidofovir as adjuvant therapy in laryngeal papillomatosis. We reviewed 20 reports that enrolled 185 patients with "adult onset recurrent respiratory papillomatosis" (AORRP) and 85 patients with "juvenile onset recurrent respiratory papillomatosis" (JORRP). We evaluated concentration of cidofovir, number of injections, injection interval, therapeutic response, side effects, and progression to dysplasia. RESULTS: The mean concentration of cidofovir was 7.5 mg/ml at injection. The mean number of injections per patient is 6 with 26 days between injections. The percentage of patients with dysplasia after use of cidofovir is 1.48%. The AORRP response to cidofovir is better with a 74% complete response rate, compared to 56.5% of the JORRP. CONCLUSIONS: Intralesion use of cidofovir has a good adjuvant action in RRP increasing the complete remission of the disease. The treatment does not increase the risk of laryngeal dysplasia.

The aim of this study is to evaluate the efficacy and safety of prolonged therapy with low-dose clarithromycin in patients with chronic rhinosinusitis with polyps (CRSwP) after endoscopic sinus surgery (ESS). A total of 10 patients with CRSwP were identified and subjected to bilateral ESS. In post-operative patients they were treated with nasal wash with saline solution and steroid sprays (beclomethasone). During follow-up, after 30-40 days after the operation (M = 35.4 SD = +4.33), patients reported a worsening of symptoms with onset of nasal obstruction; reduction/loss of smell; headache; onset of viscous secretions and therefore all patients continued therapy with saline nasal irrigation, topical steroid therapy and started macrolide (clarithromycin 500 mg/pill: 1 pill/day for 3 days a week for 1 month). 22-item SinoNasal Outcome Test (SNOT-22) and a score to the endoscopic evaluation (endoscopic appearance score, EAS) before and after treatment were performed to evaluate efficacy of treatment. The results of the SNOT-22 and EAS showed statistically significant improvements (p < 0.05) for some parameters such as: the need to blow nose, sneezing, hyposmia, viscous mucous secretions about the SNOT-22 and reduction of secretions and edema of the nasal mucosa about the EAS. The preliminary results of our study show that the low-dose clarithromycin for a period of 1 month can improve patient complaints with CRSwP not only through the antibacterial properties but also for the immunomodulatory characteristics.
RESUMO
Leptin is a peptide that plays a key role in the control of satiety, energy expenditure, food intake and various reproductive processes. In the last years, the expression of leptin had been found in malignant cells of various origins. The aim of this study is to evaluate leptin expression in human laryngeal squamous cell carcinoma (SCC) and to investigate its possible role in predicting prognosis. Leptin expression was determined by immunohistochemistry in pathological and healthy tissue specimens from 24 patients with laryngeal SCC. Specimens were stained with an anti-leptin antibody. All measurements were performed using a computer-based image analysis system and scale of staining intensity was determined. All tumoural specimens showed significant immunoreactivity for leptin compared to healthy tissues (p ≤ 0.05), but showed different immunoreactivity that was related to clinicopathological features. High leptin expression was not significantly related with TNM, histological grading (HG) or advanced (III and IV) clinical stage (p > 0.05). Recurrence of malignancy was found to be significantly related with high expression of leptin by Spearman's rank correlation test (r = 0.59; p = 0.002), Fisher's test (p = 0.017) and Kaplan- Meier product-limit estimate (Log-rank test, p ≤ 0.05). In particular, multivariate logistic regression analysis showed that recurrences were significantly related with nodal involvement, HG and leptin expression (p ≤ 0.05). These preliminary results suggest that leptin may be a valuable parameter for predicting prognosis in laryngeal SCC.

In this work the Authors describe the results of 17 plasmatic beta estradiol and plasmatic progesterone in a group of 10 arteriosclerotic patients before and after a test with HCG. The data proved that this drug doesn't modify statistically the plasmatic values of the mentioned steroids. These data cannot explain the mechanism of the therapeutic action of the HCG through a stimulus of the gonads.

Among the researches concerning the therapeutic mechanism of HCG in the arteriosclerotic disease, in this work the Authors report the values of prolactin before and after a stimulus with HCG in a group of 10 arteriosclerotic patients. The prolactin values are not modified by HCG and would not confirm the eventual direct or indirect mediation of the hypophysis in the above mentioned therapeutic action.
