Long-term carcinologic results of advanced esthesioneuroblastoma: a systematic review.

Surgical resection followed by radiotherapy can be considered like the optimal treatment modality for limited esthesioneuroblastoma. However, therapeutic management of locally advanced tumors remains a challenge. The aim of our study was to access and compare the oncologic results of the different treatment modalities in advanced esthesioneuroblastoma. We performed a systematic review using the Medline, and Cochrane database in accordance with PRISMA criteria and included all the cases of advanced esthesioneuroblastoma published between 2000 and 2013. We also retrospectively included 15 patients with an advanced esthesioneuroblastoma managed at our tertiary care medical center. Long-term survival rates defined as the time from diagnosis or randomization to the date of death or last follow-up were evaluated for each treatment with Kaplan-Meier survival curve analyses. 283 patients have been included. The mean follow-up was 78 months. Five-year highest survival rates were obtained in patients treated by surgery associated with radiotherapy. Ten-year highest survival rates were obtained in patients treated by the association of surgery, radiotherapy and chemotherapy (p = 0.0008). Within the surgical group, 5-year highest survival rates were obtained in patients treated by endoscopic resection (p = 0.003). Surgical resection combined with radiotherapy offers the gold standard of care. Adjuvant chemotherapy seems to improve the long-term survival in patients with locally advanced esthesioneuroblastoma. Endoscopic resection in advanced tumors should be discussed on a case-by-case basis.

The frontal branch of the facial nerve: can we define a safety zone?

PURPOSE: The temporal branch of the facial nerve, a particularly important branch in facial expression, is commonly exposed to surgical trauma. The frontal branch is the most important branch of the temporal branch in the clinical point of view. However, it does not really define in the international nomenclature. The objective of this study was to clearly identify this branch, to perform a cartography of the crossing areas of this branch; and therefore to define statistically a zone of safety within the fronto-temporal region. METHOD: We used 12 fresh cadavers to perform 24 facial nerve dissections. After the identification of the facial nerve, the branches of the temporofacial trunk were identified, dissected and followed till their penetration. We measured the relationship of the frontal branch with the zygomatic arch, temporal vessels and lateral border of the orbit. We conducted a statistical study to assess the risk of injury of this branch within the temporal region. RESULTS: We observed an important variability in the distribution of this branch in the temporal region. We defined three zones of decreasing safety at the level of three interest landmarks: at the level of the inferior part of the zygomatic arch, we estimated an elevated risk of nerve injury (>85%) from 22.6 to 26.06 mm in front of the tragus; at the level of the superior part of the zygomatic arch, we estimated an elevated risk of nerve injury (>85%) from 27.46 to 30.43 mm in front of the tragus; at the level of the lateral border of the orbit, we estimated an elevated risk of nerve injury (>85%) from 16.20 to 19.17 mm behind this landmark. CONCLUSIONS: There exists no real area of anatomical safety in the temporal region. It seems, however, possible to define areas of relative safety that would be of great help for the surgeon or the morphologist wishing to approach pathologies of this region.

Sialendoscopy learning curve: comparing our first and last 100 procedures.

OBJECTIVES: Sialendoscopy is a relatively new minimally invasive technique that permits direct salivary tree visualization and is important in obstructive sialadenitis management and treatment. The present study aimed to examine the sialendoscopy learning curve between March 2009 and March 2013. METHODOLOGY: We compared the first and last 100 sialendoscopies performed in our department with regard to anaesthesia type, operating time, success rate, technical difficulty, major complications, and clinical improvement. RESULTS: General anaesthesia rates were 63% and 38% (P = 0.0004) among the first and last 100 sialendoscopies, respectively. Among the first and last 100 procedures, respectively, average operating times were 39 and 25 minutes (P = 0.00055) for diagnostic sialendoscopies and 68 and 65 minutes (P = 0.35) for interventional sialendoscopies. Successful stone extraction rates were 65% and 90.2% (P = 0.0058) among the first and last 100 procedures, respectively, while the corresponding rates of successful stenosis dilation were 92.5% and 97.1% (P = 0.27). Technical difficulty was encountered in 25% and 17% (P = 0.164) of the first and last 100 sialendoscopies, respectively. Neither group experienced major complications. All patients tolerated the procedures well and had excellent outcomes. CONCLUSION: Progressive learning regarding sialendoscopy enabled more frequent operation under local anaesthesia, thus better meeting the requirements of a minimally invasive technique. We were able to decrease the operative time in diagnostic sialendoscopy. These two factors support the inclusion of diagnostic sialendoscopy into the diagnostic panel in obstructive glandular diseases.

Validity of cervical auscultation in the screening for aspiration.

INTRODUCTION: Cervical auscultation could improve the performance of bedside swallowing test to predict aspiration, especially silent aspiration. The aim of this study is to compare the predictive values of bedside swallowing test performed with and without cervical auscultation by logopedist students who had intensive training on cervical auscultation. MATERIALS AND METHODS: 64 patients were included in the study. They all underwent swallowing test alone, combined swallowing test and cervical auscultation, and videofluoroscopic swallowing study as defined gold standard. Two logopedist students, at the end of their training, performed the auscultation and noted their results. RESULTS: 128 tests were performed, 96% of the tests were judged positive for aspiration. When comparing the results of the two different clinical tests, the detection of clinical signs is not improved by the addition of auscultation. Using a penetration aspiration scale threshold >5, the area under the curve measured for the swallowing test alone was significantly higher than that measured for the combined tests (p = 0.03) (0.66 for the swallowing test alone (95% CI between 0.49 and 0.83), and 0.50 for the combined tests (95% CI between 0.31 and 0.69). CONCLUSION: This study showed no advantage in performing cervical auscultation with bedside swallowing test. Cervical auscultation seems to hamper the assessment, mainly the perception of wet voice and laryngeal motion. These results are compatible with literature but need further confirmation using studies performed with trained logopedists.

[Transsexualism: from diagnosis to management]. / Transsexualisme: du diagnostic à la prise en charge thérapeutique.

The transsexualism or gender dysphoria is a pathology during which an individual does not recognize himself in his sexual identity and wishes to change it: in that it must be differentiated from the sexual ambiguities (hermaphrodism, pseudohermaphroditism) in which the sexual phenotype is not clearly established. In France the number of transsexuals is estimated at approximately 50,000 people. Since 2009 the transsexualism is not any more considered as a mental illness, it remains regarded as a long term illness. The objective of this article is to present the recent evolutions concerning the management of transsexual patients seeking feminization.
