Combined cervicosternotomy and cervicotomy for true retrosternal goiters: a surgical cohort study.

OBJECTIVE: Intrathoracic goiters are a heterogeneous group characterized by limited or extensive substernal extension. Whereas the former can be treated through cervicotomy, the latter sometimes requires a cervicosternotomy. Whether cervicosternotomy leads to more morbidity remains unclear. This study aimed to compare intra- and postoperative morbidity in patients treated by cervicotomy or cervicosternotomy for intrathoracic goiters and standard thyroidectomy. METHODS: In a prospectively gathered cohort undergoing thyroid surgery (2010-2019) intra- and postoperative morbidity of cervicotomy (N = 80) and cervicosternotomy (N = 15) for intrathoracic goiters was compared to each other and to a 'standard' thyroidectomy (N = 1500). RESULTS: An intrathoracic extension prior to surgery was found in 95 (6%) of all thyroidectomies. Eighty patients (84%) were operated by cervicotomy and 15 (16%) by cervicosternotomy. The risk of temporary recurrent laryngeal nerve palsy was much higher in the cervicosternotomy group (21%) compared to cervicotomy (4%) and standard thyroidectomy (3%). The risk of temporary hypocalcemia after cervicotomy (28%) was comparable to a standard thyroidectomy (32%) but higher after cervicosternotomy (20%). No cases of permanent hypocalcemia or laryngeal nerve palsy were observed in both groups with substernal extension. The need for surgical reintervention was significantly higher in the cervicotomy group (6%) compared to cervicosternotomy (0%) and standard thyroidectomy (3%). CONCLUSION: In patients undergoing thyroid surgery for an intrathoracic goiter, cervicosternotomy was associated with more temporary laryngeal nerve palsy, but none of the interventions resulted in higher risks of permanent nerve damage, permanent hypocalcemia, or reintervention for bleeding. Reintervention was even more common after cervicotomy compared to cervicosternotomy. LEVEL OF EVIDENCE: IV.

Intra-operative vagal neuromonitoring predicts non-recurrent laryngeal nerves: technical notes and review of the recent literature.

BACKGROUND: During thyroid surgery, extreme caution must be taken not to harm the recurrent laryngeal nerve to avoid vocal cord palsy. A non-recurrent laryngeal nerve (NRLN) is a rare anatomical variation that is extremely vulnerable during thyroid surgery. METHODS: Description of two NRLN during thyroid surgery discovered early by using continuous intra-operative vagal nerve neuromonitoring and review of the literature. RESULTS: During thyroid surgery, we use continuous intra-operative vagal nerve neuromonitoring starting with checking vagal nerve signals. It is essential to start stimulation in the most proximal portion of the carotid sheath. An absent pre-dissection signal on the right vagal nerve with a positive signal on the left vagal nerve indicates a non-recurrent course of the right laryngeal nerve. Post-operatively computed tomography scan (CT-scan) was performed and showed an associated extra-anatomical course of the subclavian artery also known as an arteria lusoria. CONCLUSION: The NRLN is an important surgical challenge because unilateral palsy can lead to permanent hoarseness. This anomaly emphasizes the importance of a thorough surgical dissection and the use of intra-operative vagal nerve neuromonitoring. Our method of continuous intra-operative vagal nerve monitoring makes it possible to predict a non-recurrent laryngeal nerve in an early stage during surgery.

Robotic-assisted parathyroidectomy through lateral cervical approach: first results in Belgium.

OBJECTIVE: A parathyroidectomy has been the treatment of choice for primary hyperparathyroidism. Especially the improved imaging techniques have led to minimally invasive techniques. Aim of this study was to evaluate our experience with robot-assisted parathyroidectomy through lateral cervical approach. STUDY DESIGN: Prospective clinical cohort. METHODS: All consecutive patients who underwent a robotic-assisted parathyroidectomy for primary hyperparathyroidism since 2011 were enrolled in this study. Demographic data, biometrics, imaging data and surgery data were collected. Main outcomes were postoperative hypocalcemia, recurrent laryngeal nerve paralysis and other postoperative complications. RESULTS: Twenty-two patients were enrolled. When patients with conversion were excluded (39%) mean operating time was 69 min. In all patients a normal value of serum PTH-levels was achieved 4 h postoperatively. Mean value of serum calcium was 2.92mmol/L preoperative and 2.33mmol/L postoperative. There was no persistent hypocalcemia in any of our patients. 87% was discharged on the first postoperative day. Esthetic results were excellent. CONCLUSIONS: Robotic-assisted parathyroidectomy through lateral cervical approach is a safe and feasible procedure in patients with posteriorly localized parathyroid adenomas. Preoperative imaging techniques are crucial to detect the exact location.

Review of publications on the possible advantages of a direct cheek incision for accessory parotid gland masses.

Lesions of the accessory parotid gland (APG) are rare and surgical management is generally under-discussed. The surgical approach should provide complete resection, while minimising complications and aesthetic complaints. The current study reviews recent publications on the surgical management of APG masses, and discusses the advantages, and limitations of, and our experience with, direct cheek incision. Papers on the surgical management of APG masses published in the last 10 years were systematically searched. Information was obtained regarding the surgical approach, type of excision, and postoperative complications. In the included studies, 253 APG masses were selected for analysis, whereof six were treated with the direct cheek incision. Although no local recurrence or postoperative complications were observed after this, the approach was usually not recommended due to a higher reported risk of recurrence and complications in older papers. More recent studies, however, indicate that the direct cheek incision should be considered as a valuable alternative to standard approaches in selected patients.

Efficacy and complications of orbital fat decompression in Graves' orbitopathy: a systematic review and meta-analysis.

In Graves' orbitopathy, surgical decompression is often needed for functional and aesthetic reasons. This meta-analysis was performed to assess the efficacy and safety of fat removal orbital decompression (FROD) alone to treat exophthalmos in Graves' orbitopathy. A systematic search was conducted in PubMed/MEDLINE, Web of Science, and Cochrane Library for studies published before August 2018. Random-effects meta-analyses were applied; weighted means and weighted proportions with corresponding 95% confidence intervals (CI) were calculated. Study quality and quality of evidence for each individual outcome were analyzed. Of 1908 records initially identified, 13 observational studies were selected, representing 4820 orbits in 2514 patients. Weighted Hertel exophthalmometry was 23.10mm (95% CI 21.77-24.43mm) preoperative and 19.31mm (95% CI 17.81-20.81mm) postoperative. The weighted mean difference was 3.81mm (95% CI 3.41-4.21mm). Five studies reported an improvement of diplopia after surgery, occurring in 943 of 1172 patients (weighted proportion 0.50, 95% CI 0.15-0.85). Persistent new onset diplopia was reported in five studies, or 124 of 1277 patients (weighted proportion 0.15, 95% CI 0.03-0.27). No serious adverse events were reported. Results support the effectiveness and safety of FROD to treat mild-to-moderate exophthalmos in Graves' orbitopathy. Prospective and controlled trials are needed to improve the level of evidence.

New placement of recording electrodes on the thyroid cartilage in intra-operative neuromonitoring during thyroid surgery.

OBJECTIVE: During thyroid surgery, extreme caution is needed not to harm the recurrent laryngeal nerve and to avoid vocal cord palsy. Intra-operative neuromonitoring became increasingly popular as an adjunct to the gold standard of visual identification of the recurrent laryngeal nerve (RLN). Electromyographic (EMG) responses are normally recorded by electrodes attached to the endotracheal tube. Alteration in position can lead to false loss of signal. We developed thyroid cartilage electrodes that can be fixed directly onto the thyroid cartilage. STUDY DESIGN: Prospective clinical cohort METHODS: Thyroid surgery with intra-operative neuromonitoring using both endotracheal tube-based electrodes and thyroid cartilage electrodes was performed in 25 patients undergoing thyroid surgery. EMG data were collected and reported as median and interquartile ranges (IQR), and the results were compared with the x Wilcoxon signed-rank test for paired measurements. RESULTS: After stimulating vagal nerve (VN), recurrent laryngeal nerve (RLN) and external branch of the superior laryngeal nerve (EBSLN), significantly higher EMG amplitudes were measured before and after thyroid resection for the thyroid cartilage (TC) electrodes, in all comparisons except for the right VN. At the level of the left EBSLN, median amplitude of 560 mV (IQR 190-1050) before and 785 mV (IQR 405-3670) after resection was noted. At the level of the right EBSLN, median amplitude of 425 µV (IQR 257-698) before and 668 mV (IQR 310-1425) after resection was noted. Median amplitudes of 760 mV (IQR 440-1180) and 830 mV (IQR 480-1490) were noted at the left RLN, median amplitudes of 695 mV (IQR 405-1592) and 1078 mV (IQR 434-1895) were noted at the right RLN. CONCLUSION: Thyroid cartilage electrodes appear to be a feasible and reliable alternative for endotracheal electrodes.

Sequential dual-site High-Definition transcranial Direct Current Stimulation (HD-tDCS) treatment in chronic subjective tinnitus: study protocol of a double-blind, randomized, placebo-controlled trial.

BACKGROUND: Chronic tinnitus is a highly prevalent symptom, with many patients reporting considerable effects of tinnitus on quality of life. No clear evidence-based treatment options are currently available. While counseling-based methods are valuable in some cases, they are not sufficiently effective for all tinnitus patients. Neuromodulation techniques such as high-definition transcranial direct current stimulation (HD-tDCS) are proposed to have positive effects on tinnitus severity but, to date, these effects have not been proven conclusively. The proposed trial will investigate the hypothesis that chronic tinnitus patients receiving HD-tDCS will report a positive effect on the impact of tinnitus on daily life, as compared to patients receiving sham stimulation. METHODS: This study proposes a randomized, double-blind, placebo-controlled trial with parallel group design. A total of 100 chronic tinnitus patients will be randomly allocated to an experimental group or a sham group, with allocation stratified according to gender and tinnitus severity. Patient and researcher will be blinded to the patient's allocation. Patients will undergo six sessions of sequential dual-site HD-tDCS of the left temporal area and the right dorsolateral prefrontal cortex. Evaluations will take place at baseline, immediately following treatment, and at three and six months after the start of the therapy. The primary outcome measure is the change in Tinnitus Functional Index (TFI) score. Secondary outcome measures include audiological measurements, cortical auditory evoked potentials, the Repeatable Battery for the Assessment of Neuropsychological Status adjusted for hearing-impaired individuals (RBANS-H), and supplementary questionnaires probing tinnitus severity and additional symptoms. By use of a linear regression model, the effects of HD-tDCS compared to sham stimulation will be assessed. DISCUSSION: The objective of this study is to evaluate whether HD-tDCS can reduce the impact of tinnitus on daily life in chronic tinnitus patients. To date, published trials on the effects of HD-tDCS on tinnitus suffer from a lack of standardization and few randomized controlled trials exist. The proposed study will be the first adequately powered trial to investigate the effects of sequential dual-site HD-tDCS on tinnitus severity. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03754127 .

Short-term effect of short, intensive speech therapy on articulation and resonance in Ugandan patients with cleft (lip and) palate.

OBJECTIVES: The purpose of the current study was to assess the short-term effectiveness of short and intensive speech therapy provided to patients with cleft (lip and) palate (C(L)P) in terms of articulation and resonance. METHODS: Five Ugandan patients (age: 7.3-19.6 years) with non-syndromic C(L)P received six hours of individualized speech therapy in three to four days. Speech therapy focused on correct phonetic placement and contrasts between oral and nasal airflow and resonance. Speech evaluations performed before and immediately after speech therapy, including perceptual and instrumental assessment techniques, were compared. RESULTS: Post-therapy, improvement of speech was noted for most of the patients, although to varying degrees. Clinically relevant progress of objective nasalance values and/or articulation was obtained in four patients. Overall, two patients showed normal speech intelligibility, while three patients required additional speech therapy. CONCLUSION: These preliminary short-term results demonstrate that short and intensive speech therapy can be effective for patients with C(L)P in countries with limited access to speech-language therapy. However, further research is needed on the long-term effectiveness and the advantages of applying this treatment protocol in countries with good access to speech therapy. LEARNING OUTCOMES: The reader will be able to (1) list the challenges in resource poor-countries to achieve access to speech-language therapy services, (2) describe when the application of speech therapy is appropriate in patients with C(L)P, (3) describe the speech therapy that can be applied to reduce compensatory articulation and resonance disorders in patients with C(L)P, and (4) list the (possible) advantages of short, intensive speech therapy for both resource-poor and developed countries.

Facial transplantation: history and update.

BACKGROUND: Composite tissue allografting (CTA) represents the essence of reconstructive surgery, combining principles of solid organ transplantation (SOT) and modern plastic surgery techniques. The purpose of this article is to give a review of the history of facial CTA and an update of the cases that have been operated so far worldwide. METHODS: A systematic review of the medical literature was performed. Ten relevant publications were selected and analyzed for clinical data of the patients, surgical aspects of transplantation, complications and outcome. RESULTS: The past 9 years, 31 face transplants have been performed worldwide. The main indication was posttraumatic deformity. In all cases standard triple drug immunosuppression as used in SOT was successfully used and at least 1 period of acute rejection was seen in all patients, controllable with conventional immunosuppressive regimens. Overall functional outcomes are good and satisfaction rate is high, surpassing initial expectations. The main complications are opportunistic infections; 4 deaths occurred. CONCLUSIONS: Facial CTA is a life changing procedure and has led to new treatment options for patients with complex, devastating and otherwise unreconstructable facial deformities to restore appearance and overall wellbeing in a single operation. The key to success lies in the selection of the appropriate patient, who is stable, well-motivated and therapy compliant. Thorough screening and follow-up by a multidisciplinary team, well prepared surgical approach and intensive, early rehabilitation are all crucial factors for minimizing complications and a safe and rapid recovery.

Harlequin syndrome after thyroidectomy for compressive retrosternal goiter. Case report and review of the literature.

A 74-year-old woman with known euthyroid multinodular retrosternal goiter necessitated an urgent intubation at home, due to acute respiratory distress evoked by tracheal compression. Extubation after a few days failed, and she underwent an urgent total thyroidectomy. During postoperative extubation the patient developed suddenly unilateral facial flushing and sweating at the left side, without ptosis of the left levator palpebrae superioris. These symptoms persisted during the next 24 hours. The skin at the right side of the face remained uninvolved. In the early postoperative period this appearance recurred at moments of emotions, exercise or heat. Beside this, the patient had a normal recovery. Six weeks later this reaction couldn't be provoked anymore. 'Harlequin' syndrome (unilateral facial flushing and sweating) is caused by a lesion of the controlateral sympathetic chain at the levels T2 and T3. It is unknown if the sweating and vasodilation at the "healthy" side is normal or if it is a reaction of hyperactivity.

Speech characteristics in a Ugandan child with a rare paramedian craniofacial cleft: a case report.

The purpose of this study is to describe the speech characteristics in an English-speaking Ugandan boy of 4.5 years who has a rare paramedian craniofacial cleft (unilateral lip, alveolar, palatal, nasal and maxillary cleft, and associated hypertelorism). Closure of the lip together with the closure of the hard and soft palate (one-stage palatal closure) was performed at the age of 5 months. Objective as well as subjective speech assessment techniques were used. The speech samples were perceptually judged for articulation, intelligibility and nasality. The Nasometer was used for the objective measurement of the nasalance values. The most striking communication problems in this child with the rare craniofacial cleft are an incomplete phonetic inventory, a severely impaired speech intelligibility with the presence of very severe hypernasality, mild nasal emission, phonetic disorders (omission of several consonants, decreased intraoral pressure in explosives, insufficient frication of fricatives and the use of a middorsum palatal stop) and phonological disorders (deletion of initial and final consonants and consonant clusters). The increased objective nasalance values are in agreement with the presence of the audible nasality disorders. The results revealed that several phonetic and phonological articulation disorders together with a decreased speech intelligibility and resonance disorders are present in the child with a rare craniofacial cleft. To what extent a secondary surgery for velopharyngeal insufficiency, combined with speech therapy, will improve speech intelligibility, articulation and resonance characteristics is a subject for further research. The results of such analyses may ultimately serve as a starting point for specific surgical and logopedic treatment that addresses the specific needs of children with rare facial clefts.

Normative nasalance data in Ugandan english-speaking children.

AIMS: The aim of this study was to obtain normative nasalance values for typically developing Ugandan English-speaking children as a reference point for clinical practice and further research. METHODS: Sixty-nine typically developing Ugandan children (35 males and 34 females, 2.7-13.5 years of age) participated in the study. Nasalance scores were obtained with the Nasometer while children repeated 4 sustained sounds, 14 repeated syllables, 15 sentences (12 oral, 3 nasal) and 2 texts ('Rainbow Passage' and 'Zoo Passage'). Data were analyzed for gender and age dependence. RESULTS: No significant effects of age or gender on nasalance values were obtained; hence, normative values for the overall group were reported. The average nasalance scores for Ugandan English-speaking children were 17 and 64% for the oral and nasal sentences and 33 and 14% for the oronasal and oral text, respectively. CONCLUSION: The normative values are important as a reference point to assess the impact of several surgical procedures and several surgical timing strategies on speech in Uganda.

The role of the internal mammary vessels as recipient vessels in secondary and tertiary head and neck reconstruction.

BACKGROUND: Successful microsurgical free tissue transfer for head and neck reconstruction highly depends on the quality of the recipient vessels. In most cases, vessels near the site of resection are available; however, when the bilateral vascular network in the neck is compromised or inaccessible due to prior surgery and/or irradiation, alternatives have to be sought. METHODS: Secondary or tertiary head and neck reconstruction was performed using the internal mammary vessels (IMVs) as recipient vessels in seven patients who had undergone previous neck dissection and radiation therapy. Indications were: tracheal-oesophageal fistula or stenosis (n = 4), oesophageal-cutaneous fistula (n = 1), saliva fistula (n = 1) and oral cancer (n = 1). Free flaps used for reconstruction were radial forearm flap (FRFF) (n = 5), anterolateral thigh flap (ALT) (n = 3) and transverse rectus abdominis myocutaneous flap (TRAM) (n = 1). Within two patients an additional ALT flap was necessary for soft-tissue coverage and resurfacing of the neck. The IMVs were separately exposed in a standard fashion over the second or third rib. The pedicle of the flap was anastomosed anterograde and end-to-end to the recipient vessels in all cases. Mean pedicle length was 14.3 cm (11-20 cm), with a mean distance of 9.8 cm (7-13 cm) between the resection and recipient vessel site. RESULTS: All patients were tumour free at time of re-operation and no sign of radiation injury was observed in the recipient vessels. All flaps survived and all patients healed without major complications. Mean follow-up time was 18 months. Four patients died of local recurrence or distant metastases during follow-up. CONCLUSION: In the vessel-depleted neck, the IMVs are a reliable and easy accessible recipient area for microsurgical reconstruction of the head and neck. Surgical management and technique refinements for dissection of the vessels are discussed. In combination with free flaps with a long pedicle, especially perforator flaps, vein grafts are unnecessary and microsurgery can safely be performed outside the zone of injury.

Phototoxic reaction after parathyroid surgery: case report and review of the literature.

BACKGROUND: A woman of 41 years old underwent surgery for primary hyperparathyroidism. She developed a long-lasting sharply demarcated erythematous skin reaction, appearing one hour after parathyroid surgery. This erythematous reaction felt like sunburn and was limited to the light exposed skin of the operation field, leading to the diagnosis of a phototoxic reaction. Since this phototoxic reaction occurred just after changing the operation lamp from a halogen type to a Light-Emitting Diode (LED) type, we suspected that the type of operation lamp could be a part of the cause of this phototoxic reaction. This is because our department has never before diagnosed phototoxic reactions (with a halogen type of operation lamp) during methylene blue (MB) assisted parathyroid surgery. METHODS: To investigate the cause of this phototoxic reaction, we performed an analysis of the adverse effects of all administered peroperative drugs and an evaluation of altered operation conditions. RESULTS: MB, used as a peroperative surgical marker of the parathyroid glands, was the most likely causal agent of this phototoxic reaction. Emission spectrum analysis of the operation light shows that the new LED operation lamp gives a high intensity of blue light. This may have resulted in activation of MB leading to a phototoxic reaction. CONCLUSIONS: To our knowledge, this is the first described phototoxic reaction in adults due to MB used as peroperative marker. Although rare, this potential side effect should be considered when using high doses of MB in combination with high intensity of blue light.

Impact of tongue reduction on overall speech intelligibility, articulation and oromyofunctional behavior in 4 children with Beckwith-Wiedemann syndrome.

OBJECTIVE: The purpose of this study was to determine the impact of partial glossectomy (using the keyhole technique) on speech intelligibility, articulation, resonance and oromyofunctional behavior. PATIENTS AND METHODS: A partial glossectomy was performed in 4 children with Beckwith- Wiedemann syndrome between the ages of 0.5 and 3.1 years. An ENT assessment, a phonetic inventory, a phonemic and phonological analysis and a consensus perceptual evaluation of speech intelligibility, resonance and oromyofunctional behavior were performed. RESULTS: It was not possible in this study to separate the effects of the surgery from the typical developmental progress of speech sound mastery. Improved speech intelligibility, a more complete phonetic inventory, an increase in phonological skills, normal resonance and increased motor-oriented oral behavior were found in the postsurgical condition. The presence of phonetic distortions, lip incompetence and interdental tongue position were still present in the postsurgical condition. CONCLUSION: Speech therapy should be focused on correct phonetic placement and a motor-oriented approach to increase lip competence, and on functional tongue exercises and tongue lifting during the production of alveolars. Detailed analyses in a larger number of subjects with and without Beckwith-Wiedemann syndrome may help further illustrate the long-term impact of partial glossectomy.

Parent and child ratings of satisfaction with speech and facial appearance in Flemish pre-pubescent boys and girls with unilateral cleft lip and palate.

The purpose of this controlled study is to determine satisfaction with speech and facial appearance in Flemish pre-pubescent children with unilateral cleft lip and palate. Forty-three subjects with unilateral cleft lip and palate and 43 age and gender matched controls participated in this study. The Cleft Evaluation Profile was used to assess the perceived satisfaction for individual features related to cleft care. Both the cleft palate subjects and their parents were satisfied with the speech and facial appearance. The Pearson χ(2) test revealed significant difference between the cleft palate and the control group regarding hearing, nasal aesthetics and function, and the appearance of the lip. An in depth analysis of well specified speech characteristics revealed that children with clefts and their parents significantly more often reported the presence of an articulation, voice and resonance disorder and experienced /s/ /r/ /t/ and /d/ as the most difficult consonants. To what extent the incorporation of specific motor oriented oral speech techniques regarding the realisation of specific consonants, attention to vocal and ear care, and the recommendation of secondary velopharyngeal surgery, with the incorporation of primary correction of the cleft nose deformity simultaneously with primary lip closure, will aid these patients are future research subjects.

Metabolic tumour volume. Prognostic value in locally advanced squamous cell carcinoma of the head and neck.

PURPOSE: Evaluate the predictive and prognostic value of semi-quantitative FDG-PET variables derived from pretreatment FDG-PET images in patients suffering from locally advanced squamous cell carcinoma of the head and neck (SCCHN), treated by means of concomitant radiochemotherapy. PATIENTS, METHODS: 40 patients with newly diagnosed SCCHN that were treated with concomitant radiochemotherapy underwent FDG-PET/CT for treatment planning; 18 patients had neck dissection prior to their baseline scan and to receiving radiochemotherapy. FDG-PET images were used to calculate metabolic tumour volumes using region growing and a threshold of 50% (MTV50) of primary lesions and involved lymph nodes as well as the mean and maximum standard uptake value (SUVmean and SUVmax) of the primary tumours. RESULTS: Neither SUVmean nor SUVmax values of the primary tumour were significantly different between responders and non-responders whereas MTV50 values of the primary tumour proved significantly higher in non-responders. SUVmean, SUVmax and MTV50 of the primary tumour were not predictive for overall or disease free survival. Contrariwise, dichotomized summed MTV50 values (cut-off≥31 cm3) of the primary tumour and involved lymph nodes in patients that didn't have neck dissection prior to radiochemotherapy were predictive for disease free and overall survival in both univariate and multivariate analysis (p≤0.05). CONCLUSION: Summed MTV50 values of both the primary tumour and involved lymph nodes provided independent prognostic information on disease free and overall survival.

FDG uptake in primary squamous cell carcinoma of the head and neck. The relationship between overexpression of glucose transporters and hexokinases, tumour proliferation and apoptosis.

AIM: This study aimed at assessing the relationship between over-expression of glucose transporters and hexokinases, tumour proliferation and apoptosis corrected for cellularity and partial volume corrected (pvc) FDG SUV values in primary squamous cell carcinoma of the head and neck (pSCCHN). PATIENTS, METHODS: In 27 consecutive patients suffering from pSCCHN, FDG SUVmax and mean pvc values of the primary tumour were derived from a pre-surgical routine staging FDG PET/CT examination. GLUT-1, GLUT-3, HK-1, HK-3 expression, tumour proliferation (Ki-67 staining) and the number of apoptotic cells (cleaved caspase-3 staining), corrected for tumour cellularity, were subsequently assessed on the corresponding post-surgically obtained biopsies and tumour specimens. FDG SUVmax and mean pvc values of pSCCHN were correlated with the corresponding histological findings. RESULTS: FDG SUV max and mean pvc values correlated significantly: with GLUT-1 scores r = 0.408 (p = 0.04) and r = 0.439 (p = 0.03) as well as with the number of apoptotic cells r = 0.529 (p = 0.008) and r = 0.484 (p = 0.017). The number of apoptotic cells also correlated to GLUT-3 scores: r = 0.62 (p = 0.001) and GLUT-1 scores r = 0.528 (p = 0.008). CONCLUSION: FDG SUV pvc proved significantly related to GLUT-1 expression by tumour cells and to the absolute number of apoptotic cells. The latter finding warrants further exploration and confirmation by additional studies.

Speech intelligibility of children with unilateral cleft lip and palate (Dutch cleft) following a one-stage Wardill-Kilner palatoplasty, as judged by their parents.

This study determined the intelligibility (words, sentences and story telling) of 43 children (mean age 4.9 years) with unilateral cleft lip and palate who received a Wardill-Kilner palatoplasty, as judged by their parents and determined the influence of age and gender. A comparison with normative data for intelligibility of 163 Dutch speaking children was made. Each child and the parents completed The Dutch intelligibility test. Measures reported include group mean intelligibility percentages for words, sentences and story telling for children aged 2.5-5.0 and 5.0-7.6 years. A significant correlation between age of the children and intelligibility was measured. No significant gender-related differences were found. An interesting finding is the absence of significant difference in intelligibility percentage between the children with cleft palate and the normative data for story telling. The reported intelligibility percentages provide important prognostic reference information for surgeons who perform palatoplasty and speech pathologists who assess the speech production of children with cleft palate.

Long-term impact of tongue reduction on speech intelligibility, articulation and oromyofunctional behaviour in a child with Beckwith-Wiedemann syndrome.

The purpose of the present case study was to determine the long-term impact of partial glossectomy (using the keyhole technique) on overall speech intelligibility and articulation in a Dutch-speaking child with Beckwith-Wiedemann syndrome (BWS). Furthermore the present study is meant as a contribution to the further delineation of the phonation, resonance, articulation and language characteristics and oral behaviour in a child with BWS. Detailed information on the speech and language characteristics of children with BWS may lead to better guidance of pediatric management programs. The child's speech was assessed 9 years after partial glossectomy with regard to ENT characteristics, overall intelligibility (perceptual consensus evaluation), articulation (phonetic and phonological errors), voice (videostroboscopy, vocal quality), resonance (perceptual, nasometric assessment), language (expressive and receptive) and oral behaviour. A class III malocclusion, an anterior open bite, diastema, overangulation of lower incisors and an enlarged but normal symmetric shaped tongue were present. The overall speech intelligibility improved from severely impaired (presurgical) to slightly impaired (5 months post-glossectomy) to normal (9 years postoperative). Comparative phonetic inventory showed a remarkable improvement of articulation. Nine years post-glossectomy three types of distortions seemed to predominate: a rhotacism and sigmatism and the substitution of the alveolar /z/. Oral behaviour, vocal characteristics and resonance were normal, but problems with expressive syntactic abilities were present. The long-term impact of partial glossectomy, using the keyhole technique (preserving the vascularity and the nervous input of the remaining intrinsic tongue muscles), on speech intelligibility, articulation, and oral behaviour in this Dutch-speaking child with congenital macroglossia can be regarded as successful. It is not clear how these expressive syntactical problems demonstrated in this child can be explained. Certainly they are not part of a more general developmental delay, hearing problems or cognitive malfunctioning. To what extent the presence of expressive syntactical problems is a possible aspect of the phenotypic spectrum of children with BWS is subject for further research. Multiple variables, both known and unknown can affect the long-term outcome after partial glossectomy in a child with BWS. The timing and type of the surgical technique, hearing and cognitive functioning are known variables in this study. But variables such as children's motivation, the contribution of the motor-oriented speech therapy, the parental articulation input and stimulation and other family, school and community factors are unknown and are all factors which can influence speech outcome after partial glossectomy. Detailed analyses in a greater number of subjects with BWS may help further illustrate the long-term impact of partial glossectomy.
