Implementing a standardised discharge analgesia guideline to reduce paediatric post tonsillectomy pain.

OBJECTIVES: To reduce readmission for pain control post-paediatric tonsillectomy. INTRODUCTION: Paediatric tonsillectomy is a common procedure in the UK. Uncontrolled pain at home is a common reason for re-admission and therefore adequate analgesic control following paediatric tonsillectomy is vital for a smooth post-operative recovery. Analgesic regimens at a district general hospital in England were audited and a standardised protocol was subsequently implemented. METHODS: A retrospective audit from September 2014 to August 2015 was completed. Discharge analgesic regimens and readmission rates post-tonsillectomy for recurrent tonsillitis in 2-17 year-old children were studied in a large general hospital in the United Kingdom. A standardised weight-based algorithm was used to dose scheduled regular paracetamol for 2 weeks. Second cycle prospective audit ran from December 2015 to November 2016. RESULTS: In cycle 1, 151 children (mean age, 7.9 years) underwent tonsillectomy for tonsillitis, 25 (16.6%) of whom were readmitted. 12 (7.9%) experienced postoperative haemorrhage, 13 (8.6%) required pain control, and one (1.2%) had infection. The discharging analgesic regimen varied widely and often included purchase of over-the-counter ibuprofen and paracetamol. In cycle 2, 118 children (mean age, 8.8 years) underwent tonsillectomy, 17 (14.4%) were readmitted; 12 (10.2%) had post-operative haemorrhage, 0 needed pain control, 5 (4.2%) had other problems. There was a significant reduction in readmission for pain control (p = 0.0027) from 7.3% to 0% in the study. There was no significant change in overall readmission rate (16.6%-14.4%) or postoperative haemorrhage rate (8.9% overall). DISCUSSION: Analgesia prescription post tonsillectomy varies widely and over the counter prescriptions of ibuprofen and paracetamol is based on age rather than weight with patients receiving inadequate analgesic doses. A readily available standardised postoperative analgesic protocol can significantly reduce readmission rates for pain control following paediatric tonsillectomy.

Acoustic parameters of speech: Lack of correlation with perceptual and questionnaire-based speech evaluation in patients with oral and oropharyngeal cancer treated with primary surgery.

BACKGROUND: Acoustic evaluation of speech is the least explored method of speech evaluation in patients with oral cavity and oropharyngeal cancer. The purpose of this study was to explore acoustic parameters of speech and their correlation with questionnaire evaluation and perceptual evaluation in patients with oral cavity and oropharyngeal cancer. METHODS: One hundred seventeen subjects (65 consecutive patients with oral cavity and oropharyngeal cancer and 52 controls) participated in this study. Formant frequencies (by Linear Predictive Coding), Speech Handicap Index, and London Speech Evaluation scale were used for acoustic evaluation, questionnaire evaluation, and perceptual evaluation, respectively. RESULTS: Men showed significant elevation in second formant (F2) values for patients with oral cavity cancer and those who underwent surgery alone. Female patients with early T classification cancers and those who underwent surgery and chemoradiation showed significant reduction in the mean F2 values. Importantly, however, acoustic evaluation parameters did not correlate with either perceptual evaluation or questionnaire evaluation parameters, although there was moderate correlation between questionnaire evaluation and perceptual evaluation speech parameters. CONCLUSION: Acoustic evaluation modalities have no clear role in the management of patients with oral cavity and oropharyngeal cancer.

Evaluation of swallowing by Sydney Swallow Questionnaire (SSQ) in oral and oropharyngeal cancer patients treated with primary surgery.

This work aimed at evaluating patients' swallowing functions by a newly validated swallow-specific questionnaire, the Sydney Swallow Questionnaire (SSQ), in a cohort of oral and oropharyngeal cancer patients. Mean/median SSQ scores were calculated and compared with study variables using the Mann-Whitney U test and Kruskal-Wallis test. The mean composite SSQ scores (SD) for the base of tongue, oral tongue, and tonsillar cancer patients were 663.8 (382.8), 456.2 (407.6), and 283.0 (243.1), respectively (p = 0.005); for advanced vs. early T stage disease they were 918.1 (319.5) vs. 344.8 (292.1) (p ≤ 0.001); for patients <60 years vs. ≥60 years they were 549.3 (415.1) vs. 314.0 (247.3) (p = 0.02); and for patients with reconstruction vs. without reconstruction they were 676.5 (410.5) vs. 331.9 (286.5) (p = 0.002). SSQ is a useful tool for evaluation of swallowing in head and neck cancer patients. Site of cancer, T stage, patient's age, and reconstruction directly affect post-treatment swallow outcome.

Evaluation of speech outcomes using English version of the Speech Handicap Index in a cohort of head and neck cancer patients.

The aim of this study was to explore post-treatment speech impairments using English version of Speech Handicap Index (SHI) (first speech-specific questionnaire) in a cohort of oral cavity (OC) and oropharyngeal (OP) cancer patients. Sixty-three consecutive OC and OP cancer patients in follow-up participated in this study. Descriptive analyses have been presented as percentages, while Mann-Whitney U-test and Kruskall-Wallis test have been used for the quantitative variables. Statistical Package for Social Science-15 statistical software (SPSS Inc., Chicago, IL) was used for the statistical analyses. Over a third (36.1%) of patients reported their speech as either average or bad. Speech intelligibility and articulation were the main speech concerns for 58.8% and 52.9% OC and 31.6% and 34.2% OP cancer patients, respectively. While feeling of incompetent and being less outgoing were the speech-related psychosocial concerns for 64.7% and 23.5% OC and 15.8% and 18.4% OP cancer patients, respectively. Worse speech outcomes were noted for oral tongue and base of tongue cancers vs. tonsillar cancers, mean (SD) values were 56.7 (31.3) and 52.0 (38.4) vs. 10.9 (14.8) (P<0.001) and late vs. early T stage cancers 65.0 (29.9) vs. 29.3 (32.7) (P<0.005). The English version of the SHI is a reliable, valid and useful tool for the evaluation of speech in HNC patients. Over one-third of OC and OP cancer patients reported speech problems in their day-do-day life. Advanced T-stage tumors affecting the oral tongue or base of tongue are particularly associated with poor speech outcomes.

Evidence for treatment strategies in sinonasal adenocarcinoma.

Adenocarcinomas of various types account for 10% to 20% of all primary malignant neoplasms of the nasal cavity and paranasal sinuses. There is a general consensus that the optimal treatment of adenocarcinoma is surgery and postoperative radiotherapy. The purpose of this report was to review the results of this combined treatment as well as other treatment strategies and their outcome. Most series present outcome data from a heterogeneous group of patients, with a wide variety of tumor subtypes presenting at differing stages, who received a variety of treatment strategies. Surgical excision remains the treatment of choice. The choice of approach is determined by what will best allow complete excision of the disease. Endoscopic techniques, if feasible for complete removal of the tumor, offer results comparable to those of external approaches with lower morbidity. Although clear evidence to support the use of radiotherapy in sinonasal adenocarcinoma is difficult to obtain, local control rates of combined treatment strategies for advanced cases are comparable to less advanced cases with surgery alone, suggesting a positive role for postoperative radiotherapy. However, the importance of thorough surgical resection should be stressed.

Evaluation of factors affecting post-treatment quality of life in oral and oropharyngeal cancer patients primarily treated with curative surgery: an exploratory study.

The aim was to explore the impact of important clinico-demographic factors on the post-treatment quality of life (QOL) in surgically treated oral and oropharyngeal cancer patients. 63 consecutive follow-up oral and oropharyngeal cancer patients treated primarily with surgery were recruited. 55 patients sent the completed questionnaires and finally included in this study. QOL and important sub-domains of the QOL were assessed. Mean QOL scores (SD) were computed, level of significance was set at P < 0.05. The mean composite QOL score and standard deviation (SD) for oral and oropharyngeal cancer patients were 76.6 (15.2) and 73.4 (13.9), respectively. Patients with higher T-stage (T3 and T4) and higher overall-stage (III and IV) had lower mean QOL scores as against early T (T1 and T2) and overall early-stage (I and II); mean scores (SD) 64.3 (13.6) and 72.3 (13.8), and 76.6 (13.6) and 81.7 (14.1), respectively. Younger patients had lower mean scores (SD) than older patients; mean QOL scores (SD) 69.7 (14.0) and 79.6 (SD), respectively. Patients with reconstruction had lower mean QOL scores as compared to those without reconstruction; mean scores (SD) 67.6 (16.0) and 77.4 (12.5), respectively. In conclusion, tumor-stage, overall-stage, age of patients, and reconstruction had a significant direct effect on the post-treatment QOL of oral and oropharyngeal cancer patients.

An exploratory study of the influence of clinico-demographic variables on swallowing and swallowing-related quality of life in a cohort of oral and oropharyngeal cancer patients treated with primary surgery.

There are insufficient data on swallowing and the consequences of its dysfunction in patients with cancers of the oral cavity (OC) and oropharynx (OP) that are treated with primary surgery. The study attempts to explore the effect of important clinico-demographic variables on post-treatment swallowing and related quality of life (QOL) in post-surgical OC and OP cancer patients. Sixty-two consecutive OC and OP cancer patients completed the MD Anderson Dysphagia Inventory (MDADI) questionnaire. Mean scores were computed. Comparison of scores based on mean ranks were performed using Mann-Whitney U test or Kruskal-Wallis test. Level of significance was set at P ≤ 0.02. Adjustments were made for multiple comparisons. Significantly worse mean (SD) QOL scores were observed in late T-stage (T3/T4) versus early T-stage (T1/T2) patients for global domain, physical domain, functional domain and emotional domains [44.4 (21.9) vs. 78.7 (22.7) (P < 0.001); 50.0 (9.4) vs. 75.9 (16.3), (P < 0.0001); 57.8 (20.6) vs. 84.1 (16.7), (P < 0.001) and 55.2 (18.0) vs. 78.5 (16.3), (P < 0.001)], respectively. Patients undergoing reconstruction versus without reconstruction had worse QOL scores; 58.8 (26.9) versus 79.5 (22.8), (P < 0.01); 61.2 (15.1) versus 76.4 (17.5), (P = 0.002); 65.4 (20.5) versus 86.3 (15.9), (P < 0.0001) and 63.3 (18.8) versus 79.8 (16.3), (P < 0.01), respectively, for global, physical, functional and emotional domains. Advanced T-stage, reconstruction, younger age and base of tongue tumours have a negative impact on post-treatment swallow function and related QOL in these patients.

Development and validation of first-ever speech-specific perceptual speech evaluation tool for patients with head and neck cancer: the London speech evaluation (LSE) scale.

BACKGROUND: The aim of this study was to develop and validate the first ever speech-specific perceptual speech-evaluation tool for patients with head and neck cancer. METHODS: Five speech parameters (intelligibility, articulation, speech rate, nasality, and asthenia) and overall grade were included and evaluated. Speech samples of 117 subjects were recorded on electroglottograph equipment using a standard protocol and were independently judged and rated by 3 experienced speech and language therapists and re-rated 12 weeks apart. RESULTS: Among patients the Cronbach's alpha (α) coefficients for internal consistency for connected speech were 0.89, whereas for single words the α coefficients ranged between 0.80 and 0.84. The Spearman's correlation coefficients for intra-rater reliability for connected speech and words varied between 0.30 and 0.90 and 0.49 and 0.76, respectively, whereas for inter-rater reliability the coefficients ranged between 0.53 and 0.99 and 0.56 and 0.99, respectively. For construct validity, the Spearman's correlation coefficient ranged between 0.41 and 0.55. CONCLUSIONS: The London Speech Evaluation (LSE) scale demonstrated a high reliability and validity in our cohort of patients with head and neck cancer. surgery.

Anatomic distribution of cervical lymph node spread in parotid carcinoma.

BACKGROUND: The pattern of distribution of cervical nodal involvement from primary parotid carcinomas has not been extensively described. METHODS: All cases of parotid carcinoma over a 10-year period treated at our institution were reviewed. Data from the patients with cervical metastases were analyzed. These findings were pooled with previously published data on topography of cervical lymph nodes from parotid carcinomas. RESULTS: Of 80 cases, 15 had cervical metastases (N+) in our series. When pooled with the data from all other reports, a total of 66 N+ cases were available for analysis. Twenty-eight percent of cases had involvement of level I, 59% had level II, 52% had level III, 38% had level IV, and 41% had level V. There were frequent skip metastases to level V but all were ipsilateral. CONCLUSION: The diffuse distribution of cervical nodal metastases does not support a high echelon neck dissection or radiotherapy fields limited to the upper chain in the management of cervical nodal disease.

Systematic review and meta-analysis of the adverse effects of thyroidectomy combined with central neck dissection as compared with thyroidectomy alone.

OBJECTIVES/HYPOTHESIS: Meta-analysis to assess the increased morbidity of performing a central neck dissection with thyroidectomy to thyroidectomy alone. STUDY DESIGN: Systematic review and meta-analysis. METHODS: Published articles were searched for using PubMed. Suitability was assessed by using predefined inclusion/exclusion criteria. Meta-analysis on the data was performed using the Mantel-Haenszel method and a risk difference calculated. RESULTS: Five studies with a total of 1,132 patients were included. For every 7.7 central neck dissections performed with thyroidectomy, there was one extra case of temporary hypocalcemia when compared to thyroidectomy alone. There was no significant increased risk of permanent hypocalcemia or temporary or permanent vocal cord palsy when a central neck dissection was performed in addition to a thyroidectomy. CONCLUSIONS: The benefits of prophylactic central neck dissection in differentiated thyroid carcinoma may be debated but there is no increased permanent morbidity by performing the procedure at the same time as thyroidectomy.

Cancer-specific transgene expression mediated by systemic injection of nanoparticles.

The lack of safe and efficient systemic gene delivery vectors has largely reduced the potential of gene therapy in the clinic. Previously, we have reported that polypropylenimine dendrimer PPIG3/DNA nanoparticles are capable of tumor transfection upon systemic administration in tumor-bearing mice. To be safely applicable in the clinic, it is crucial to investigate the colloidal stability of nanoparticles and to monitor the exact biodistribution of gene transfer in the whole body of the live subject. Our biophysical characterization shows that dendrimers, when complexed with DNA, are capable of forming spontaneously in solution a supramolecular assembly that possesses all the features required to diffuse in experimental tumors through the enhanced permeability and retention effect. We show that these nanoparticles are of sizes ranging from 33 to 286 nm depending on the DNA concentration, with a colloidal stable and well-organized fingerprint-like structure in which DNA molecules are condensed with an even periodicity of 2.8 nm. Whole-body nuclear imaging using small-animal nano-single-photon emission computed tomography/computer tomography scanner and the human Na/I symporter (NIS) as reporter gene shows unique and highly specific tumor targeting with no detection of gene transfer in any of the other tissues of tumor-bearing mice. Tumor-selective transgene expression was confirmed by quantitative reverse transcription-PCR at autopsy of scanned animals, whereas genomic PCR showed that the tumor sites are the predominant sites of nanoparticle accumulation. Considering that NIS imaging of transgene expression has been recently validated in humans, our data highlight the potential of these nanoparticles as a new formulation for cancer gene therapy.
