RESUMO
OBJECTIVE: The risk-benefit ratio of central neck dissection (CND) in patients affected by papillary thyroid carcinoma (PTC) without clinical or ultrasonographic (US) evidence of neck lymph node metastasis (cN0) is currently debated. The aim of this study was to evaluate long-term outcome of CND on locoregional recurrence, distant metastasis, survival, and postoperative complications in a large series of patients with cN0-PTC. STUDY DESIGN: Observational retrospective controlled study. METHODS: Clinical records of patients (n=610) surgically treated for cN0-PTC at the Otolaryngology Unit of the Arcispedale Santa Maria Nuova-IRCCS, Reggio Emilia, Italy, from January 1984 to December 2008, were retrospectively reviewed. Study population was divided into three groups according to surgical treatment: Group A, total thyroidectomy (n=205); Group B, total thyroidectomy and elective ipsilateral CND (n=281); Group C, total thyroidectomy and bilateral CND (n=124). RESULTS: Of a total of 610 patients, 305 (50%) were classified as low-risk, 278 (45.57%) as intermediate-risk, and 27 (4.43%) as high-risk. Response to initial therapy was excellent in 567 patients (92.95%), acceptable in 21 (3.44%), and incomplete in 22 (3.61%), with no significant differences among groups. Locoregional recurrence was detected in 32 (5.2%) out of 610 patients. Distant metastasis was found in 15 patients (2.5%). Statistical analysis showed no significant differences in the rates of locoregional recurrence (p=0.890) or distant metastasis (p=0.538) among groups. Disease-specific mortality and overall survival did not significantly differ among groups (p=0.248 and 0.223, respectively). Rate of permanent hypoparathyroidism was significantly higher in Group C patients compared to those in Groups A and B. CONCLUSION: CND does not confer any clear advantage in the treatment of low-risk patients, regardless of surgical procedure. Instead, bilateral CND may be effective in limiting disease relapse and/or progression in patients at higher prognostic risk. Our data indicate that elective CND does not confer any clear advantage in terms of locoregional recurrence and long-term survival, as demonstrated by outcomes of the study Groups, regardless of their different prognostic risk. Elective CND allows a more accurate pathologic staging of central neck lymph nodes, despite its increasing the risk of permanent hypoparathyroidism. Intraoperative pathologic staging is a valuable tool to assess the risk of controlateral lymph node metastasis in the central neck compartment and to limit more aggressive surgery only to cases, otherwise understaged, with lymph node metastasis.

Lidocaine is commonly used for topical anesthesia of the upper airway in patient with anticipated difficult tracheal intubation undergoing awake fiberoptic intubation. Lidocaine toxicity is dose related and proportional to its plasma level. Although neurologic toxicity has been frequently observed with intravenous use, it has also been reported for topical use. We report on a case of a patient with base tongue abscess who developed sudden seizures and coma during application of topical anesthesia with lidocaine for awake fiberoptic intubation. The presence of a deep neck infection that causes hyperemia and edema of the pharyngolaryngeal mucosa may enhance transmucosal systemic absorption of local anesthetic. Moreover, conditions such as hypercarbia, dysphagia, or hepatic diseases are known to facilitate onset of lidocaine neurologic toxicity with serum concentration lower than normal. These findings should be kept in mind before administering topical anesthesia of the upper airway. In the presence of any of these conditions above, either the total dose of local anesthetic or its concentration should be reduced as much as possible.

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare anomaly causing respiratory distress in newborns. While the primary surgical technique is well established, the timing of the removal of the stents and the management of restenosis remain a matter of debate. We report a case of a female newborn affected by CNPAS with the recurrence of respiratory distress after primary surgery due to the early removal of nasal stents, causing an overgrowth of granulation tissue. This report notes that restenosis was successfully managed by repeating the procedure over a 14-day period, with soft polyvinyl chloride uncuffed tracheal tubes acting as nasal stents.

L-ascorbic acid, is a well-known molecule, sometimes used as antioxidant for skin care. Nonetheless, few studies have taken in account its utility as topical treatment for non-melanoma skin vancer. Non-melanoma skin cancer includes basal cell carcinoma and squamous cell carcinoma and is widespread worldwide with an increasing incidence. The purpose of this paper is to analyze the characteristics of L-ascorbic acid topical formulation, its percutaneous absorption and biochemical mechanism, focusing on its anti-cancer properties. In particular, it will be described how the pH and the concentration of the formulation are able to influence its distribution in the skin and tissues. We will report, the current knowledge on the pharmacokinetic aspects of L-ascorbic acid that allows us to reconsider it in the light of its ability to act as a prodrug and as an anticancer agent. Lastly, a short review with the aim to find any evidence of a possible clinical use of L-ascorbic acid for the treatment of non-melanoma skin cancer was made.
RESUMO
OBJECTIVE: Thyroid surgery may lead to postoperative complications. The aim of this paper was to determine whether the rate of postoperative hypoparathyroidism (HPT) is influenced by whether surgery is staged. DESIGN: Single-institution retrospective observational study. METHODS: The clinical records of 786 patients treated at the Otolaryngology Unit of the Azienda USL-IRCCS di Reggio Emilia between January 1990 and December 2015 were reviewed. Patients were divided into two groups according to the surgical treatment received: group TT (637 patients, 81.04%) underwent single-stage total thyroidectomy; Group cT (149 patients, 18.96%) underwent loboisthmusectomy and delayed completion total thyroidectomy. Transient and permanent HPT, assessed after 6 months of follow-up, were the primary endpoints. Risk factors of postoperative HPT were also analysed as secondary outcomes. RESULTS: Rates of transient HPT in group TT were higher than those observed in group cT, (P = 0.0057). Analysis of risk factors identified sex as an independent risk factor for transient HPT only for group TT (P = 0.0012) and the number of parathyroid glands remaining in situ (PGRIS) as an independent risk factor for transient and permanent HPT for group TT (P < 0.0001 and P = 0.0002, respectively). CONCLUSIONS: This study suggests that the risk of transient postoperative HPT is lower in patients that undergo completion thyroidectomy. Further independent risk factors for postoperative HPT are female sex and PGRIS score. In light of the growing use of conservative surgery for thyroid neoplasms, these findings could help to adequately plan surgery in order to reduce endocrine complications.

RESUMO
BACKGROUND: HIV-related Burkitt's lymphoma with initial oropharyngeal presentation is rarely reported. The aim of this paper is to report the clinical findings of an unusual case of a patient with extranodal oropharyngeal Burkitt's lymphoma as presenting disease of an unknown HIV positivity and acquired immunodeficiency syndrome. METHODS: We reported the case of a hispanic patient with extranodal oropharyngeal Burkitt's lymphoma as presenting disease of an unknown HIV positivity and acquired immunodeficiency syndrome. We describe the diagnostic work-up and treatment of this rare case of extranodal oropharyngeal Burkitt's lymphoma. RESULTS: Histological exam on oropharyngeal incision biopsy documented a Burkitt's lymphoma. The patient underwent highly active antiretroviral therapy and chemotherapy. After two years of follow-up the patient shows no signs of recurrence from disease. CONCLUSIONS: HIV-related Burkitt's lymphoma presenting with primary oropharyngeal involvement is rare, with rapidly progressing dysphagia, and does not respond to antibiotherapy. Patients should undergo incision biopsy to rule out a malignancy. In young adults, diagnosis of Burkitt's lymphoma should suggest HIV infection. The importance of a prompt diagnosis in such cases is essential to correctly adequately staging the disease to start highly active antiretroviral therapy and chemotherapy as soon as possible.

Superior canal dehiscence is a pathologic condition of the otic capsule acting as aberrant window of the inner ear. It results in reduction of inner ear impedance and in abnormal exposure of the labyrinthine neuroepithelium to the action of the surrounding structures. The sum of these phenomena leads to the onset of typical cochleo-vestibular symptoms and signs. Among them, pulsatile tinnitus has been attributed to a direct transmission of intracranial vascular activities to labyrinthine fluids. We present the first video-otoscopic documentation of spontaneous pulse-synchronous movements of the tympanic membrane in two patients with superior canal dehiscence. Pulsating eardrum may represent an additional sign of third-mobile window lesion.

Post-traumatic cricothyroid joint dislocation is reported in the literature. Trauma of the laryngeal framework is the most common cause. As a result, spontaneous non-traumatic cricothyroid joint dislocation is very rarely described. We report the case of a patient with spontaneous cricothyroid joint dislocation with the aim of reporting the diagnostic and therapeutic findings related to this rare entity. History and physical examination may suggest diagnosis. Computed tomography scan can confirm diagnosis and detect coexistence of anatomic anomalies of the neck. Reduction of dislocation may be easily performed in outpatient setting, producing immediate relief from dysphonia and neck pain. As CTJ dislocation is a speech-related disorder, appropriate speech therapy is advisable in order to avoid relapse.

In recent years, the popularity of aesthetic and cosmetic procedures, often performed in outpatient settings, has strongly renewed interest in topical anesthetics. A number of different options are widely used, alone or in combination, in order to minimize the pain related to surgery. Moreover, interest in local anesthetics in the treatment of some painful degenerative conditions such as myofascial trigger point pain, shoulder impingement syndrome, or patellar tendinopathy is increasing. Numerous clinical trials have shown that lidocaine-tetracaine combination, recently approved for adults aged 18 or older, is effective and safe in managing pain. The present paper gives an overview of the recent literature regarding the efficacy and safety of lidocaine-tetracaine combination use.
RESUMO
Herein we describe a rare case of neuroglial heterotopia (ectopic mature cerebral tissue) incidentally detected by F-FDG PET/CT. A 52-year-old female patient underwent F-FDG PET/CT for metabolic characterization of a left pulmonary nodule. F-FDG PET/CT revealed increased radiopharmaceutical uptake corresponding to the pulmonary nodule pathologically described as adenocarcinoma. Furthermore, an area of increased F-FDG uptake corresponding to a lesion in the left nasal cavity was detected. Endoscopic biopsy of the nasal lesion showed the presence of ectopic mature cerebral tissue suggesting the presence of neuroglial heterotopia.

OBJECTIVES/HYPOTHESIS: The aim of this study was to identify any possible predictive factors of lateral neck recurrence in patients with papillary thyroid carcinoma with no ultrasonographic and/or cytological evidence of lymph node metastasis at time of diagnosis. The influence of lateral neck recurrence on survival was also investigated. STUDY DESIGN: Observational retrospective study. METHODS: Retrospective review of clinical records of 610 patients surgically treated for papillary thyroid carcinoma with clinically negative lymph nodes at the Otolaryngology Unit of the Arcispedale Santa Maria Nuova-IRCCS, Reggio Emilia, Italy, from January 1984 to December 2008. RESULTS: Lateral neck recurrences were ipsilateral to the primary tumor in all cases and were associated with the occurrence of more aggressive histological variants and central neck metastasis. Lateral neck recurrences were more frequently observed in patients with distant metastases and were associated with a reduced disease-specific survival. CONCLUSION: Lateral neck compartment ipsilateral to the tumor was the most common site of recurrence, with about half of cases appearing in the first 28 months of follow-up. In patients with papillary thyroid carcinoma, detection of lateral neck metastases prior to first surgery is crucial to surgical planning. Aggressive histological variants and postsurgical evidence of lymph node metastasis from papillary thyroid carcinoma in central neck compartment are associated with a higher risk of lateral neck recurrence. In these patients, a closer postsurgical ultrasound surveillance of the lateral neck compartments seems worthwhile. LEVEL OF EVIDENCE: 4.

BACKGROUND AND AIM OF THE WORK: Necrotizing fasciitis is a rapidly progressing life-threatening infection of the deep fat and fascial layers, which rarely occurs in the neck. The aim of the paper is to report the management of this rare condition, pointing out the role of multimodality in achieving the cure of the patient. METHODS: We report our experience regarding the management of two cases of necrotizing fasciitis of the neck successfully treated with surgical and medical treatment. DISCUSSION: Early diagnosis of necrotizing fasciitis of the neck plays a central role in preventing progression of the disease. Multimodal treatment should be mandatory. CONCLUSIONS: Securing of the airway, immediate aggressive surgical debridement, and antibacterial agents administration represent the effective treatment in preventing progression of the disease. Intensive care support should be considered as an integral part of treatment.
