Enhanced recovery after surgery protocols in functional endoscopic sinus surgery for patients with chronic rhinosinusitis with nasal polyps: a randomized clinical trial.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are a series of perioperative care to optimize preoperative preparation, prevent postoperative complications, minimize stress, and speed up recovery. This study aimed to assess the impact of ERAS protocols for functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS: One hundred and two patients with CRSwNP undergoing FESS were randomly divided into the ERAS group and the control group. The outcomes of the Self-Rating Anxiety Scale (SAS), Visual Analogue Scale (VAS), Medical Outcomes Study Sleep Scale (MOS-SS) and Kolcaba Comfort Scale Questionnaire (GCQ) were determined in both groups. The serum levels of C-reactive protein (CRP) were compared preoperatively and 24 hours postoperatively. RESULTS: The ERAS group had a significantly better SAS scores than did the control group (28 [24, 35] vs. 43 [42, 47], Z = 5.968, P < 0.001). The rhinalgia and headache scores at 2, 24 and 48 hours postoperatively were lower in the ERAS group than that in the control group (all P < 0.001). The outcomes of the MOS-SS (43 [42, 39] vs. 28 [22, 35], Z = 7.071, P < 0.001) and GCQ (76 [68, 87] vs. 64 [50, 75], Z = 4.806, P < 0.001) were significantly different between the two groups. No significant difference was found in the preoperative CRP levels between the two groups (1.3 [0.6, 2.8] vs. 0.5 [0.5, 1.2], Z = 3.049, P > 0.05); However, the CRP level in 24 hours postoperatively was significantly lower in the ERAS group than that in the control group (2.5 [1.4, 3.9] vs. 6.6 [3.8, 9.0], Z = 5.027, P < 0.001). The incidence rates of complications, such as nausea/emesis (χ = 0.343, P > 0.05), hemorrhage, aspiration and tumble, were not increased in the ERAS group compared with those in the control group. The ERAS group had a significantly shorter length of hospital stay (5 [4, 5] days vs. 8 [8,9] days, Z = 8.939, P < 0.001) and hospitalization expenses ($ 2670 [2375, 2740] vs. $3129 [3116, 3456], Z = 8.514, P < 0.001). CONCLUSIONS: ERAS protocols might optimize FESS for patients with CRSwNP by reducing psychological and physical stress, shortening the length of hospital stay and lowering hospitalization expenses without increasing postoperative complications.

The Role of Tracheostomy in Anaplastic Thyroid Carcinoma.

Even though management of thyroid cancer is generally standardized and has an overall excellent long-term outcome, anaplastic thyroid cancer (ATC) continues to be a major diagnostic and therapeutic challenge. ATC is an uncommon thyroid malignancy with a poor prognosis. American Thyroid Association guidelines acknowledge the complexity of airway management in these patients. We studied the literature with the aim of providing guidance in airway management in ATC. Tracheotomy can facilitate completion of palliative treatment in those patients with ATC and stridor. Given the short life expectancy of these patients, a balanced decision must be made regarding the role and timing of tracheotomy.

Management of lymph node metastases from an unknown primary site to the head and neck (Review).

Cancer of unknown primary site (CUP) is an intriguing clinical phenomenon found in ~3-9% of all head and neck cancers. It has not yet been determined whether CUP forms a distinct biological entity with specific genetic and phenotypic characteristics, or whether it is the clinical presentation of metastasis in patients with an undetected primary tumor and no visible clinical signs. The treatment of patients with cervical lymph node metastases from CUP remains controversial, due to the lack of randomized clinical trials comparing different treatment options. Consequently, treatment is currently based on non-randomized data and institutional policy. In the present review, the range and limitations of diagnostic procedures are summarized and an optimal diagnostic work-up is recommended. The initial preferred diagnostic procedures include fine-needle aspiration biopsy (FNAB) and imaging. Although neck dissection followed by postoperative radiotherapy is the the most generally accepted approach, other curative options may be used in certain patients, such as neck dissection alone, nodal excision followed by postoperative radiotherapy, or radiotherapy alone. There remains controversy regarding target radiation volumes, ranging from ipsilateral neck irradiation to prophylactic irradiation of all the potential mucosal sites and both sides of the neck. When no primary lesion is identified with imaging and endoscopy in patients without history of smoking and alcohol abuse, molecular profiling of an FNAB sample for human papillomavirus and/or Epstein-Barr virus is required.

[Radiobiological characteristics and MRN complex expression of human nasopharyngeal carcinoma cell lines].

OBJECTIVE: To study the radiobiological characteristic of human nasopharyngeal carcinoma cell lines CNE1 and CNE2 and the changes in expression MRN (Mre11-Rad50-Nbs1) complex in the cell lines exposed to irradiation. METHODS: CNE1 and CNE2 were irradiated by a linear accelerator. Radiobiological characteristics were detected by colony assay and MTT assay. MRN complex expression were examined by Western blot. RESULTS: Surviving fraction at 2 Gy (SF2), quasi-threshold Dose (Dq), and mean lethal dose (Do) of CNE1 were 0.56, 1.449 Gy and 1.480 Gy; SF2, Dq, and Do of CNE2 were 0.44, 0.776 Gy and 1.685 Gy, respectively. Survival fraction of CNE1 at the day 6 after 4 Gy irradiation was 0.59 and that of CNE2 was 0.79 when compared with control, with the up-regulated expressions of Rad50 in CNE1 and Mre11, Rad50 and Nbs1 in CNE2 (P < 0.05). CONCLUSIONS: CNE1 and CNE2 were sensitive to radiation, but there were radioresistance cells in CNE2. The expressions of some components of MRN complex were up-regulated to repair DNA lesions induced by radiation.
