Background Surgeons have searched for the technique or medication that will produce a 'painless tonsillectomy'; however, this seems to be an impossible goal. Previous studies have shown that perioperative acupuncture may be a useful adjunct for acute postoperative pain and that acupuncture, in addition to nonsteroidal anti-inflammatory drugs, is effective in adults for the treatment of postoperative swallowing pain after tonsillectomy. Acupuncture has been shown to be safe in children. A retrospective review of acupuncture for posttonsillectomy pain in juvenile patients showed a significantly reduced pain score immediately after treatment. Aim To examine whether acupuncture, in addition to conventional analgesic treatment, will be effective in the treatment of posttonsillectomy pain in children. Methods We conducted a randomized, controlled, single-blinded study comparing conventional postoperative analgesic treatment with the same regime plus acupuncture to assess whether postoperative treatment of children aged 3-12 years undergoing tonsillectomy with acupuncture will reduce pain and to examine possible unwanted effects of this treatment. Results Sixty children were recruited and randomly divided into a study group and a control group. The results indicate that in the study group, there was less pain, less analgesic drug consumption, and higher patient/parent satisfaction with analgesic treatment scores. No adverse effects were recorded. Conclusions Acupuncture, in addition to conventional analgesic treatment, is an effective treatment for posttonsillectomy pain. Acupuncture is safe and well received by children and their parents. © 2015 John Wiley & Sons Ltd.

We previously reported on head and neck tumor xenografts that the tumor regression induced by a triple combination of irradiation (RT), anti-EGFR and anti-angiogenic therapies was followed, after treatment arrest, by tumor re-growth characterized by activation of the AKT signaling pathway. Since mTOR is the main AKT-related messenger, the aim of this study was to add the mTOR inhibitor temsirolimus to a tri-therapy with RT plus anti-EGFR and anti-angiogenic drugs in order to improve anti-tumor effects. The human head and neck cancer cell line CAL33 (over-expressing EGFR and secreting VEGF-A) was xenografted in nude mice. Treatment (20 mice per treatment group) was administered for 2 weeks and consisted of either vehicle (control), temsirolimus (5 mg/kg i.p. five times a week), tri-therapy with RT (6 Gy three times a week) combined with cetuximab (0.5 mg/kg i.p. five times a week) and bevacizumab (5 mg/kg i.p. five times a week) or the temsirolimus-tri-therapy association. The time to reach a tumor volume of 2000 mm3 was significantly different between the four treatment groups (Log Rank p < 0.0001), with a median of 29.5, 44.5, 67.0 and 70.0 days for control, temsirolimus, tri-therapy and combination groups, respectively. The combination of temsirolimus plus tri-therapy produced the longest growth-inhibiting effects (tri-therapy versus combination, p = 0.01). No significant interaction was observed between temsirolimus and the tri-therapy, suggesting that temsirolimus, on the one hand, and RT-cetuximab-bevacizumab, on the other, exert additive effects on tumor growth inhibition. These decreases observed on tumor growth were corroborated by the parallel decreases observed on tumor proliferation (Ki67) and on anti-apoptotic markers (Bcl2). These results suggest that temsirolimus exhibits synergistic antiproliferative effects when administered in combination with irradiation, anti-EGFR and anti-angiogenic therapies in head and neck cancer patients. © 2011 Elsevier Ltd.

Pierre Robin sequence (PRS) is a congenital condition with a heterogeneous and imprecise developmental prognosis. We conducted a longitudinal prospective study analyzing the long-term developmental outcome of a consecutive series of 39 children with PRS who had an a priori good prognosis (isolated PRS or PRS associated with a Stickler syndrome) but severe neonatal disorders (respiratory and feeding difficulties). Psychomotor and cognitive levels, speech, and eating behavior were assessed at 15 months of age and 3 and 6 years of age; 24 of the oldest children were interviewed at age 11 or 12 years. Results were analyzed by diagnosis, extent of respiratory and feeding disorders, and treatment modalities. Cognitive scores were within normal ranges and increased over time, from 90.5 at 15 months of age to 109.1 at 6 years. The 24 oldest children were enrolled in the appropriate junior high school grade at the normal age. For children 15 months of age, language scores were below the average, as were scores for vocabulary at 3 years for half of the patients. At 6 years, children's speech showed persistent rhinolalia, which was mild (47%), moderate (11%), or major (11%). At 15 months of age, 74% of the children had satisfactory eating behavior, and 15% had serious difficulties. At 3 and 6 years, 18% and 6% of the children, respectively, had eating problems. Treatment modalities had no significant effect on long-term outcome. Global developmental quotient scores were lower but not significantly for children with an associated Stickler syndrome than those with isolated PRS. Children with isolated PRS showed good prognosis. © 2013 Wiley Periodicals, Inc.

For the first time in 1979, it was described by Wang that the infrahyoid musculocutaneous flap (IHMC flap) appears to be extremely suitable for medium-sized head and neck defect. Nevertheless, this flap remains unpopular because of its pretended lack of reliability. The aim of this study is to describe the surgical key points and to expose its main advantages. An IHMC flap was achieved on 32 patients to repair tissue loss due to surgical resection of a squamous cell carcinoma of the upper aero-digestive tract, from March 2006 to January 2010. Medical records of each of these patients were retrospectively analysed by the investigators including the detailed clinical, pathological and operative reports. No patient presented with total flap necrosis. However, we experienced four skin paddles necrosis. In two cases, the necrosis was total and in two cases partial. All donor sites were closed primarily without any tension. One patient showed a major dehiscence of the neck skin incision that required a pectoralis major flap. The IHMC flap is reliable and the harvesting technique is simple when the surgical key points are respected. Its advantages make it a convenient flap for medium-sized head and neck defect. © 2011 Springer-Verlag.

Human epidermal growth factor receptor 2 (HER-2) is a well recognized prognostic and predictive factor in breast cancer. However, the role of HER-2 in thyroid cancer remains controversial. The aim of this study was to evaluate HER-2 expression in differentiated thyroid cancer (DTC) and determine whether there is an association with other clinical and pathological characteristics. A total of 69 patients with DTC were investigated, 58 of whom had papillary and 11 follicular carcinomas. HER-2 was detected by immunohistochemical examination on sections from formalin-fixed, paraffin-embedded tumor tissues. Tumors with HER-2 expression classed as +1 and +2 were retested with chromogenic

Background: Pregnancy rhinitis manifests as nasal congestion, with resolution of symptoms after delivery. Eighteen to 30% of pregnant patients report symptoms of rhinitis. Pregnancy rhinitis may have an adverse effect on quality of life (QOL) and may cause obstructive sleep apnea (OSA), which in turn may adversely affect the outcome of pregnancy. Previous examinations of the prevalence of pregnancy rhinitis during different stages of pregnancy have been inconclusive. This study aimed to determine rhinosinusitis-specific QOL during different stages of pregnancy. Methods: A cross-sectional observation study of patients in the second and third trimesters of pregnancy using the 22-item Sino-Nasal Outcome Test (SNOT-22) was conducted in the obstetric clinic at McGill University Health Center in Montreal, Canada. Seventy-six low- risk pregnant patients were included in the study. Thirty-two patients were in the second trimester of pregnancy and 44 patients were in the third trimester. Results: Average item scores for the entire questionnaire were significantly higher (p = 0.041), indicating more severe impairment of QOL, in the third trimester in comparison with the second trimester. A comparison between women with and without preexisting allergic rhinitis, in both the second and the third trimesters, shows significantly higher SNOT-22 scores for the allergic group (p = 0.007). QOL was lower in the third trimester than in nonrhinosinusitis patients (p = 0.011). Conclusion: Rhinosinusitis-specific QOL is lower in the third trimester of pregnancy in comparison with the second trimester and also in comparison with nonrhinosinusitis patients. Increased awareness may enhance the QOL of pregnant patients, prevent OSA, and thereby positively influence the outcome of pregnancy. Copyright © 2012, OceanSide Publications, Inc.

Background The aims of this study were to determine the trends in survival of patients with anterior skull base cancer over several decades and to identify time-related changes in the demographic and clinical characteristics of this population. Methods In all, 282 patients who underwent craniofacial resection at Memorial Sloan-Kettering Cancer Center and Tel Aviv Medical Center were studied. Patients were categorized in accord with the period of surgery: early (1973-1984, n = 34), intermediate (1985-1996, n = 72), and later (1997-2008, n = 176). Results Patients operated after 1996 had higher rates of comorbidity, dural and pterygopalatine invasion, and multicompartmental involvement than those operated before 1996 (p ≤.001). There was a significant improvement in 5-year overall and disease-specific survival, from 55% and 57%, respectively, for patients operated before 1996, to 66% and 70%, respectively, for those operated after 1996 (p =.02 and p =.006, respectively). On multivariate analysis, surgery after 1996 was an independent predictor of outcome (HR, 0.39, p <.001). Conclusions The survival of patients with anterior skull base cancer is improving. Surgery after 1996 is an independent prognostic factor for an improved outcome. © 2011 Wiley Periodicals, Inc.

Objectives: Fatal complications of percutaneous dilatational tracheostomy (PDT) are rare and intraoperative fatal complications of PDT even more so. We present the unique case of a fatal nonvascular intraoperative complication of PDT, previously unreported in the medical literature. We also present a review of all previously reported fatal complications of PDT. Methods: A review of all previously reported fatal complications of PDT was conducted in order to examine the prevalent causes of death and to attempt to recommend measures designed to prevent similar fatal complications in the future. Results: Cases of death during or following PDT in which the technique is related to the cause of death have only been reported in a small number of cases. Almost all fatal complications of PDT result from vascular injury. Conclusions: Any vascular pulsation palpated over the tracheostomy site mandates preoperative ultrasound or conversion to open surgical tracheostomy. Patients with previous neck surgery, radiotherapy or unclear surgical anatomy should be regarded with caution. If a difficult intubation or a difficult procedure is anticipated, it may be preferable not to attempt PDT with a plan to convert to surgical tracheostomy if necessary but instead to perform surgical tracheostomy without attempting PDT. © 2012 Elsevier Inc.

Objective: Despite the fact that clinicians are responsible for delivering bad news, they have been shown to lack both confidence and skill in performing this basic task. The time immediately after the detection of childhood hearing loss is perceived as stressful. We conducted a qualitative study to assess parents' experiences with receiving the bad news of the detection of their child's hearing loss. Study design: Semi-structured interviews were conducted with families of children with hearing loss identified during early childhood. Setting: A rehabilitation center treating pre-school children in the north of Israel. Patients: 14 families/parents of children diagnosed prior to the implementation of a universal screening program. Main outcome measure: Parents' perceptions of the manner in which the information regarding the detection of their child's hearing loss was given, and what their feelings were at the time. Results: 50% of parents expressed dissatisfaction with the process of the breaking of the bad news. ABR is perceived by parents and health professionals alike as the definitive moment of diagnosis. The emotions experienced by parents at the moment of the breaking of the bad news were predominantly shock and upset. The meaning of the news was perceived differently under different circumstances. Information given bluntly, without empathy, was a frequent complaint. Parents repeatedly stated the importance of the formulation of a plan for the future. Conclusions: Qualitative enquiry provided valuable information. Effective strategies for the breaking of bad news should become an integral part of universal neonatal screening programs. © 2009 Elsevier Ireland Ltd.

Radiotherapy is an integral part of overall cancer therapy. One of the most serious adverse effects of irradiation concern, for long-term survivors, the development of post-radiation sarcoma (PRS) in healthy tissues located within the irradiated area. PRS have bad prognosis and are often detected at a late stage. Therefore, it is obvious that the early detection PRS is a key-point and the development of preclinical models is worthy to evaluate innovative diagnostic and therapeutic procedures. The aim of this study was to develop a spontaneous rodent model of PRS and to evaluate the potency of Positron Emission Tomography (PET) for early detection. Fifteen Wistars rats were irradiated unilateraly on the hindlimb with a single dose of 30 Gy. Sequential analysis was based on observational staging recordings, Computerized Tomography (CT) scanning and PET. Tumors were removed and, histopathological and immunochemistry analyses were performed. Among the irradiated rats, 12 sarcomas (80%) were detected. All tumors occurred naturallty within the irradiated hindlimb and were highly aggressive since most tumors (75%) were successfully transplanted and maintained by serial transplantation into nude mice. Upon serial staging recordings, using PET, was found to enable the detection of PRS earlier after irradiation than with the other methods (i.e. 11.9 1.8 vs 12.9 2.6 months). These results confirmed the interest of experimental models of PRS for the preclinical evaluation of innovative diagnostic strategies and confirmed the potency of PET for early detection of PRS. This preclinical model of PRS can also be proposed for the evaluation of therapeutic strategies.
