RESUMO

BACKGROUND: COVID-19 was declared a pandemic by the World Health Organization on March 11th, 2020. Global social lockdowns were instigated to reduce spread and prevent health-services from becoming overwhelmed. People having treatment for cancer are known to have heightened psychological/emotional burden. The combined impact of managing pandemic regulations alongside this may present additional burden. The purpose of this systematic review is to examine current evidence of the psychological and emotional impact of COVID-19 on people with cancer, early in the pandemic. METHODS: Five electronic databases were searched (Embase, Global Health, HMIC, PsychINFO, CINAHL) from September 2019 to October 2021. Qualitative, quantitative and mixed-method primary research studies exploring emotional and psychological impacts of COVID-19 on cancer patients, limited to English language, were included. Quality appraisal was conducted using the MMAT. RESULTS: Fifty-one papers, with 27,356 people from 21 countries treated for cancer, were included. 43 studies were quantitative with a survey method approach, six studies qualitative and four used a mixed methods design. MMAT score was mostly two or three. Four themes were identified: Emotional aspects and Quality of Life; Psychosocial aspects; Impact of COVID-19 on self; Impact of COVID-19 on cancer, with themes overlapping. CONCLUSION: Whilst emotional/psychological impacts such as anxiety, isolation, employment fears, and uncertainty about the future were potentially universal concerns early in the pandemic, they may have been particularly acute for people living with cancer and represent complex, overlapping factors. As COVID-19 continues to impact health-services and society, it is important to focus on any ongoing impact to the experience of cancer patients. Most of the studies reviewed used tools that do not provide deeper understanding of how and why emotional states of people with cancer were affected. Further qualitative work may reveal patterns of what was unique to cancer patients during the pandemic, compared to general populations.

RESUMO

Withdrawal symptoms are observed upon cessation of cannabis use in humans. Although animal studies have examined withdrawal symptoms following exposure to delta-9-tetrahydrocannabinol (THC), difficulties in obtaining objective measures of spontaneous withdrawal using paradigms that mimic cessation of use in humans have slowed research. The neuromodulator dopamine (DA) is affected by chronic THC treatment and plays a role in many behaviors related to human THC withdrawal symptoms. These symptoms include sleep disturbances that often drive relapse, and emotional behaviors like irritability and anhedonia. We examined THC withdrawal-induced changes in striatal DA release and the extent to which sleep disruption and behavioral maladaptation manifest during abstinence in a mouse model of chronic THC exposure. Using a THC treatment regimen known to produce tolerance, we measured electrically elicited DA release in acute brain slices from different striatal subregions during early and late THC abstinence. Long-term polysomnographic recordings from mice were used to assess vigilance state and sleep architecture before, during, and after THC treatment. We additionally assessed how behaviors that model human withdrawal symptoms are altered by chronic THC treatment in early and late abstinence. We detected altered striatal DA release, sleep disturbances that mimic clinical observations, and behavioral maladaptation in mice following tolerance to THC. Altered striatal DA release, sleep, and affect-related behaviors associated with spontaneous THC abstinence were more consistently observed in male mice. These findings provide a foundation for preclinical study of directly translatable non-precipitated THC withdrawal symptoms and the neural mechanisms that affect them.

RESUMO

PURPOSE: Intramedullary (IM) nail use for metaphyseal fracture management is problematic in long bones like the femur because the larger medullary cavity allows increased fracture motion and potentially increased implant failure and malunion/nonunion risk; Achieving effective distal femur fracture fixation is even more difficult in osteoporotic bone. Blocking screws to control IM nail movement are known to be effective for tibia fracture management. Few studies have evaluated IM nail and blocking screw use efficacy for distal femur fracture fixation in osteoporotic bone. METHODS: This study used an osteoporosis simulation synthetic bone model to evaluate retrograde IM nail fixation of a standardized non-comminuted, extra-articular distal femur fracture with and without blocking screws. The hypothesis was that use of one or two blocking screws would increase IM nail fixation stability as evidenced by greater peak IM nail load and lesser movement. A servohydraulic device under displacement control collected loading force versus movement deflection data. Shapiro-Wilk tests confirmed data normality. One-way analysis of variance and Tukey post hoc tests were used to compare condition specific loading force and movement differences. RESULT: In the coronal plane, blocking screw conditions displayed greater loading ranges (38.3 ± 2 vs. 19.1 ± 2 N, 100.5% difference) (p < 0.0001) and lesser movement (2.0 ± 0.3 vs. 6.86 ± 0.4 mm, 243% difference) (p < 0.0001). In the sagittal plane, the two blocking screw condition displayed a significantly greater loading magnitude (29.9 ± 6 vs. 20.8 ± 2.3 N, 43.8% difference) than the identical control condition without blocking screws (p = 0.018); however, movements were comparable (p = 0.82). Long-axis rotational loading failed to reveal load magnitude differences (p = 0.28); however, two different blocking screw conditions displayed decreased movement (1.32 ± 0.2 vs. 2.05 ± 0.3 mm, 53.8% difference) compared to other conditions (p ≤ 0.018). CONCLUSIONS: Use of one or two blocking screws on the medial and lateral sides of the IM nail decreased coronal plane movement in the intramedullary canal. Combining retrograde IM nail implantation with blocking screws reduced medial-lateral IM nail movement and increased fracture stability. These characteristics may help prevent fixation failure, malunion, and even nonunion in patients with a distal femur fracture in osteoporotic bone.

RESUMO

The brain-specific tyrosine phosphatase, STEP (STriatal-Enriched protein tyrosine Phosphatase) is an important regulator of synaptic function. STEP normally opposes synaptic strengthening by increasing N-methyl D-aspartate glutamate receptor (NMDAR) internalization through dephosphorylation of GluN2B and inactivation of the kinases extracellular signal-regulated kinase 1/2 and Fyn. Here we show that STEP61 is elevated in the cortex in the Nrg1+/- knockout mouse model of schizophrenia (SZ). Genetic reduction or pharmacological inhibition of STEP prevents the loss of NMDARs from synaptic membranes and reverses behavioral deficits in Nrg1+/- mice. STEP61 protein is also increased in cortical lysates from the central nervous system-specific ErbB2/4 mouse model of SZ, as well as in human induced pluripotent stem cell (hiPSC)-derived forebrain neurons and Ngn2-induced excitatory neurons, from two independent SZ patient cohorts. In these selected SZ models, increased STEP61 protein levels likely reflect reduced ubiquitination and degradation. These convergent findings from mouse and hiPSC SZ models provide evidence for STEP61 dysfunction in SZ.

RESUMO

Introduction The aim of this study was to identify the proportion of children referred to a paediatric tertiary referral centre who required admission to the paediatric intensive care unit (PICU) following surgery for obstructive sleep apnoea (OSA) and to establish risk factors for these admissions. Methods Retrospective review of case notes and the operative database was performed for all children undergoing adenotonsillectomy for sleep disordered breathing and OSA symptoms in Great Ormond Street Hospital over a 10-year period. Results Overall, 1,328 children underwent adenotonsillectomy for sleep disordered breathing and OSA. The mean age was 3.1 years (standard deviation [SD]: 1.7 years). A total of 37 (2.8%) were admitted to the PICU postoperatively (mean length of PICU stay: 1.2 days, standard deviation [SD]: 0.6 days) and 282 (21.2%) required nasopharyngeal airway (nasal prong) insertion intraoperatively. The mean length of stay on the ward following surgery was 1.4 days (SD: 0.8 days). Patients with severe OSA (apnoea-hypopnoea index [AHI] >10) and ASA (American Society of Anesthesiologists) grade ≥3 were more likely to require postoperative PICU admission (22/37 vs 381/1,291 [p<0.001] and 29/37 vs 660/1,291 [p=0.001] respectively). Severe OSA was also more common in children who required nasal prong insertion intraoperatively (186/282 vs 217/1,046, p<0.001). Conclusions Very few children referred to a paediatric tertiary referral centre actually require PICU admission following surgery. This may be in part due to the use of a nasopharyngeal airway in patients where postoperative obstruction is anticipated. In children with severe OSA (AHI >10) and an ASA grade of ≥3, nasopharyngeal airway insertion and potential admission to the PICU should be considered.

RESUMO

OBJECTIVES: To describe our experience and provide guidelines for maximum safe balloon sizes according to age in children undergoing balloon dilatation. METHOD: A retrospective review was conducted of children undergoing balloon dilatation for subglottic stenosis in a paediatric tertiary unit between May 2006 and February 2016. RESULTS: A total of 166 patients underwent balloon dilatation. Mean ( ± standard deviation) patient age was 4.5 ± 3.99 years. The median balloon size was 8 mm, the median balloon inflation pressure was 10 atm, and the mean balloon inflation time was 65.1 ± 18.6 seconds. No significant unexpected events occurred. The Pearson correlation co-efficient for the relationship between patient age and balloon size was 0.85 (p = 0.001), suggesting a strongly positive correlation. CONCLUSION: This study demonstrated that balloon dilatation is a safe procedure for airway stenosis. The results suggest using a balloon diameter that is equal to the outer diameter of the age-appropriate endotracheal tube +1 mm for the larynx and subglottis and +2 mm for the trachea.

RESUMO

PURPOSE: Head and neck rhabdomyosarcoma (HNRMS) survivors are at increased risk of developing pituitary dysfunction as an adverse event of radiotherapy. Our aim was to investigate the frequency and risk factors for pituitary dysfunction in these survivors. Secondly, we aimed to compare the prevalence of pituitary dysfunction between survivors treated with external beam radiation therapy (EBRT) and survivors treated with the ablative surgery, moulage technique after loading brachytherapy, and surgical reconstruction (AMORE) procedure. METHODS: Eighty HNRMS survivors treated in London (EBRT based) and Amsterdam (AMORE based: AMORE if feasible, otherwise EBRT) in the period 1990-2010 and alive ≥ 2 years post-treatment were evaluated. Survivors were evaluated in multidisciplinary late-effects clinics, with measurement of linear growth, determination of thyroid function, and growth hormone parameters. Additional data, such as baseline characteristics, anthropometrics, pubertal stage, and the results of additional laboratory investigations, were retrieved from patient charts. RESULTS: Pituitary dysfunction was diagnosed in 24 in 80 (30%) survivors, after a median follow-up time of 11 years. Median time to develop pituitary dysfunction after HNRMS diagnosis was 3.0 years. Risk factors were EBRT-based therapy (odds ratio [OR] 2.06; 95% confidence interval [CI] 1.79-2.46), parameningeal tumour site (OR 1.83; 95% CI 1.60-2.17) and embryonal RMS histology (OR 1.49; 95% CI 1.19-1.90). CONCLUSIONS: Radiotherapy used for the treatment of HNRMS confers a significant risk of the development of pituitary dysfunction. AMORE-based treatment in children with HNRMS resulted in less pituitary dysfunction than treatment with conventional EBRT. Our findings underscore the importance of routine early endocrine follow-up in this specific population.

RESUMO

The genetic and epigenetic factors contributing to risk for schizophrenia (SZ) remain unresolved. Here we demonstrate, for the first time, perturbed global protein translation in human-induced pluripotent stem cell (hiPSC)-derived forebrain neural progenitor cells (NPCs) from four SZ patients relative to six unaffected controls. We report increased total protein levels and protein synthesis, together with two independent sets of quantitative mass spectrometry evidence indicating markedly increased levels of ribosomal and translation initiation and elongation factor proteins, in SZ hiPSC NPCs. We posit that perturbed levels of global protein synthesis in SZ hiPSC NPCs represent a novel post-transcriptional mechanism that might contribute to disease progression.

RESUMO

OBJECTIVES: Nasal dermoids are rare developmental anomalies seen in children. This study reports the largest case series of 103 patients seen in a quaternary specialist unit over a 10-year period. We report the surgical and radiological findings and propose a new classification system, which clearly describes the extent of the lesions, thus allowing better surgical planning. METHODS: A retrospective review of case notes was conducted. Data collection included demographics, initial presentation, site of lesion, pre-operative CT and MRI imaging, surgical procedure, intraoperative findings (including depth of lesion), complications and recurrence. Surgical findings were correlated with radiological findings. RESULTS: A total of 103 patients were included in the study. The mean age at presentation was 29 months. 89% of children presented with a naso-glabellar or columellar lesion and 11% had a medial canthal lesion. All the patients underwent preoperative imaging and were treated with surgical excision. 58 children had superficial lesions, 45 had subcutaneous tracts extending to varying depths. Of these, 38 had intraosseous extension into the frontonasal bones, eight extended intracranially but remained extradural and two had intradural extension. There was good correlation between radiological and surgical findings. The superficial lesions were locally excised. The lesions with intraosseous tracts were removed via open rhinoplasty and the frontonasal bones drilled for access. Intracranial extension was approached either via a bicoronal flap and frontal craniotomy or the less invasive anterior small window craniotomy. CONCLUSIONS: This report describes the largest published cases series of nasal dermoids. The cases demonstrate the presenting features and the variable extent of the lesions. The new proposed classification; superficial, intraosseous, intracranial extradural and intracranial intradural, allows precise surgical planning. In the presence of intracranial extension, the low morbidity technique of using a brow incision and small window anterior craniotomy avoids the more invasive and commonly used bicoronal flap and frontal craniotomy.

RESUMO

This reflective piece takes a holistic approach to an older patient having a transurethral resection of the prostate, commonly known as a TURP. It concentrates on the effects of age and likely comorbidities, and how the care given at each stage--preoperatively, anaesthetically, surgically and postoperatively--by the perioperative team can help to optimise the outcome for the patient. The article offers a critical appraisal of the best evidence available which supports the development of evidence based practitioners.

RESUMO

UNLABELLED: A subpopulation of patients with asthma treated with maximal inhaled treatments is unable to maintain asthma control and requires additional therapy with oral corticosteroids (OCS); a subset of this population continues to have frequent exacerbations. Alternate treatment options are needed as daily use of OCS is associated with significant systemic adverse effects that affect many body systems and have a direct association with the dose and duration of OCS use. We compared the population demographics, medical conditions and efficacy responses of the OCS-dependent group from the DREAM study of mepolizumab with the group not managed with daily OCS. TRIAL REGISTRATION NUMBER: NCT01000506.

RESUMO

A project team from the United Kingdom Oncology Nursing Society developed a blended e-learning website to facilitate nurses to further develop their confidence and competencies in a range of skills related to assessing the holistic needs of people with cancer. The project team identified three areas which were integral to an holistic needs assessment (HNA) implementation project. These were project support information, project management skills, and practical competencies delivered in a blended e-learning package containing a series of accessible video presentations, supporting documents, and practical activities. The team worked with internal and external partners to ensure that a robust and inspiring programme was created. www.hnaforcancer.com was launched in October 2012 as a blended learning programme that incorporates e-learning on core subjects. These subjects are packaged as videoed presentations with supporting learning material and can be accessed via the UKONS website. By the end of the programme participants were equipped to identify and explore the essential requirements for HNA and care planning, more able to recognise potential need, and initiate care to prevent or minimise the risk of complications. Participants had also developed confidence and competency in new skills, including basic project management.

RESUMO

Introducción. El virus del papiloma humano (HPV por sus siglas en inglés) es una de las infecciones de transmisión sexual más frecuentes en el mundo y es descrito como el principal agente causal del cáncer cervicouterino (99,7%). En mujeres existe abundante información sobre esta infección, mientras que sus características en población masculina son poco conocidas. Material y método. Se realizó una búsqueda de bibliografía actualizada de la infección por HPV en hombres y su relación con distintos tipos de cáncer. Resultados. La infección por HPV en hombres podría estar asociada a tumores de piel, región perianal, amígdala, orofaringe, laringe, esófago, próstata y uretra. La infección por HPV generalmente es silente, por lo cual no produce síntomas o signos clínicos evidentes, provocando que un gran número de personas estén infectadas sin saberlo, lo cual constituye un problema tanto para el hombre como para su pareja sexual. Los estudios de prevalencia muestran que las zonas de mayor presencia del virus son en poblaciones jóvenes de África y América Latina, donde los programas de vacunación contra este virus tardarán en concretarse. Discusión. Es importante incorporar métodos diagnósticos para HPV en la población masculina e incrementar la vacunación de esta. Asimismo, el control periódico de la población de hombres infectados por la asociación entre HPV y cáncer es crucial, especialmente en las áreas anatómicas asociadas a las enfermedades de transmisión sexual (AU)


Introduction. Human papillomavirus (HPV) is one of most frequent sexually transmitted infections worldwide. It has been described as the principal agent for cervical uterine carcinoma (99.7%). There is abundant information on this infection in women, however, its characteristics in the male population still remains unclear. Materials and methods. A search of updated bibliography on HPV infection in males and its relationship with several forms of cancer was conducted. Results. HPV infection in men could be associated to skin, perianal, tonsils, oropharynx, pharynx, esophagus, prostate and urethra carcinoma. HPV infection is usually silent, so that there are no clear symptoms or clinical signs. Therefore, there are many infected people who are unaware that they have HPV infection. This is a problem for men as well as their sexual partner. Prevalence studies show that the areas having the greatest presence of the HPV virus are in the young populations of Africa and Latin America. This is where the vaccine programs against this virus are slow in materializing. Discussion. It is important to incorporate diagnosis methods in male population and to increase HPV vaccine in men. Furthermore, periodic control of the HPV-infected male population is crucial, especially in the anatomical areas associated to sexual transmission diseases (AU)

RESUMO

OBJECTIVE: Treatment options for large subglottic haemangioma include steroids, laser ablation, open excision, tracheostomy and, more recently, propranolol. This article aims to present the Great Ormond Street Hospital guidelines for using propranolol to treat infantile isolated subglottic haemangioma by ENT surgeons. METHODS: The vascular malformations multidisciplinary team at Great Ormond Street Hospital has developed guidelines for treating infantile haemangioma with propranolol. RESULTS: The Great Ormond Street Hospital guidelines for propranolol treatment for infantile subglottic haemangioma include investigation, treatment and follow up. Propranolol is started at 1 mg/kg/day divided into three doses, increasing to 2 mg/kg/day one week later. On starting propranolol and when increasing the dose, the pulse rate and blood pressure must be checked every 30 minutes for the first 2 hours. Lesion response to treatment is assessed via serial endoscopy. CONCLUSION: Recent reports of dramatic responses to oral propranolol in children with haemangioma and acute airway obstruction have led to increased use. We advocate caution, and have developed guidelines (including pre-treatment investigation and monitoring) to improve treatment safety. Propranolol may in time prove to be the best medical treatment for subglottic haemangioma, but at present is considered to be still under evaluation.

RESUMO

OBJECTIVES: Adenoidectomy and/or tonsillectomy are commonly performed in tertiary pediatric hospitals for the management of obstructive sleep apnea, often in children with significant comorbidities. This study examines the peri-operative course of a large series of complex patients undergoing such surgery at a major pediatric centre, reporting particularly cases of respiratory compromise requiring intensive care admission, both electively and unplanned. METHODS: This study was conducted by the pediatric ENT department at Great Ormond Street Hospital. All children undergoing adenoidectomy and/or tonsillectomy from July 2003 to December 2010 were included in this study. This involved a retrospective review of the case notes and hospital databases, with particular emphasis on those children requiring admission to the pediatric intensive care unit. RESULTS: A total of 1735 consecutive admissions for adenoidectomy and/or tonsillectomy (1627 individual patients aged 4-197 months, median 46 months) were included between 2003 and 2010 (998 adenotonsillectomies, 182 tonsillectomies and 555 adenoidectomies). In this group, 999/1627 patients (61.4%) had a diagnosis of sleep disordered breathing or sleep apnea, including 258 who had polysomnography. 407/1627 (25.0%) had no specific comorbidities which were felt likely to influence their surgical outcome. Established high risk factors included age less than 24 months (292), Down syndrome (99), neuromuscular problems (314), craniofacial abnormalities (94), storage diseases (23), morbid obesity (20), cardiovascular disease (133), respiratory disease (261), hemoglobinopathy (76) and coagulophathy (34). 300/1735 admissions were day cases and 1082/1735 were observed for one night. 353/1735 required more than one night in hospital (294 for two to three nights). 7/1735 had primary hemorrhage necessitating return to the operating room, all after tonsillectomy. 41/1735 (38 with major comorbidities) required peri-operative intensive care admission, mostly for respiratory support. Of these, 7 were admitted pre-operatively to intensive care, and 17 were planned post-operative transfers. Only 17/1735 required unanticipated post-operative admission to intensive care. Odds ratio analysis suggested a significantly higher chance of PICU admission in children with particular comorbidities (Down Syndrome, cardiac disease, obesity, cerebral palsy, craniofacial anomalies, mucopolysaccharidoses and hemoglobinopathy) when compared to children without comorbidities. Adenotonsillectomy was associated with a higher risk of PICU admission than adenoidectomy alone, but patient age less than 24 months was not associated with significantly higher rates of PICU admission. There were no peri-operative mortalities in this cohort. CONCLUSIONS: The peri-operative course was largely uneventful for the majority of children undergoing surgery during this period, particularly given the high prevalence of sleep apnea and other risk factors in this cohort. Major complications were uncommon, with 2.4% of these selected, typically high risk cases requiring peri-operative intensive care admission. Importantly, only 1% of all admissions required unanticipated transfer to intensive care. This has informed changes in peri-operative management in this unit, with implications for other pediatric tertiary referral centres.

RESUMO

OBJECTIVE: To investigate the incidence of abnormal findings on brain MRI in paediatric cochlear implantation candidates. METHODS: Retrospective review of brain MRI scans of cochlear implant patients between 2000 and 2009 who underwent MRI brain as part of their pre-operative work-up. RESULTS: MRI scans of 162 patients were reviewed (76 female patients and 86 male patients). The mean age at time of MRI scan was 3 years 8 months. Abnormalities were detected/ reported in 49 patients (30%). The total number of abnormalities detected was 51 (two patients had two separate abnormalities each). Of the abnormalities 82% could be related to known pre-existing conditions. 18% of the abnormalities were incidental/unexpected. Incidental/unexpected abnormalities were found in 9 patients (6%). Four of the patients with incidental abnormalities required referral and further investigations (2.5%). The most common abnormality detected was white matter changes (70%). All the white matter changes were related to pre-existing known medical conditions. CONCLUSION: At our institution abnormalities detected by pre-operative brain MRI scans on cochlear implant candidates are common (30%). The majority of abnormalities are related to known pre-existing medical conditions. Incidental findings are rare (4%) and approximately half of them required further investigation or referral.

RESUMO

BACKGROUND: Surgery for paediatric airway stenosis is constantly evolving. Surgery is the primary treatment modality via either an open or endoscopic approach. The objective of this study was to review the results of laryngotracheal reconstruction (LTR) and cricotracheal resection (CTR) procedures performed at Great Ormond Street Hospital over the past 10 years. METHODS: All patients who underwent open airway reconstruction surgery from January 2000 to December 2010 were included in this study. Patients treated entirely endoscopically were excluded. The data was collected using the electronic operating theatre database and the discharge summary database. RESULTS: Complete data was available for 199 patients who underwent open airway reconstruction from January 2000 to December 2010. The procedures included single stage LTR (57, 28.6%), two stage LTR (115, 57.7%), single-stage stomal reconstruction (14), single-stage CTR (8) and two-stage CTR (5). The diagnoses at the initial airway endoscopy were laryngeal web (22), subglottic stenosis (151), posterior glottic stenosis (9), suprastomal collapse (15), supraglottic stenosis (1) and tracheal stenosis (1). For those with subglottic stenosis, the stenosis was grade 1 in 1 patient, grade 2 in 26 patients, grade 3 in 117 patients and grade 4 in 6 patients. At the completion of intervention 175/199 (87.9%) patients reported improvement in their symptoms. Amongst the subglottic stenosis group, post LTR success was achieved in 100% with grade 1 stenosis, 92.3% with grade 2 stenosis, 88.1% in grade 3 stenosis and 83.3% in grade 4 stenosis. Of the two-stage LTR procedures, 100/115 (86.9%) had their tracheostomy removed and 15/115 (13.1%) have failed decannulation. Of the single-stage LTR group, 50/57 (87.7%) patients were better both on airway examination and symptomatically postoperatively. Of the single-stage stomal reconstruction group, 13/14 (92.8%) were better symptomatically and on airway examination. Patients who underwent single-stage CTR had a better airway on examination and were symptomatically improved in all cases (8/8). For the patients who underwent two stage CTR, the tracheostomy was removed in 3/5 (60%) and retained in 2/5 (40%). For the whole group, 15/199 (7.5%) patients underwent a revision LTR. On further analysis, revision LTR was required in 4/57 (7.1%) single-stage LTR, 9/115 (7.8%) two-stage LTR, 1/5 (20%) two-stage CTR and 1/8 (12.5%) single-stage CTR. In this study complications occurred in 13/199 (6.5%). CONCLUSIONS: Subglottic stenosis in children needs to be approached on the basis of the nature and severity of stenosis and the individual patient's general health. Good outcomes are achieved with both LTR and CTR. Good results are obtained both with single-stage and two-stage LTR, but restenosis remains a problem. An individual approach is required for treatment of paediatric airway stenosis to achieve good final outcomes. The overall success rate has increased only marginally in our institution over the last 20 years.

RESUMO

OBJECTIVE: Anterior tongue reduction is indicated when macroglossia causes problems with oral hygiene, airway compromise, deglutition, articulation or orthognathic complications. Causes of macroglossia include hypothyroidism, mucopolysaccharide and lipid storage disease, lymphangioma, haemangioma, neurofibroma, and muscular macroglossia. This paper presents an 11-year experience of anterior tongue reduction at Great Ormond Street Hospital. METHOD: Retrospective study of patient medical records identified from the hospital ENT database. Anterior wedge resection was the preferred technique. RESULTS: Anterior tongue reduction was performed on 18 patients, due to cystic hygroma with tongue involvement (nine patients), Beckwith-Wiedemann syndrome (eight) and Down's syndrome (one). Anterior wedge resection was preferred, using electrocautery in the majority, except for four cases involving CO2 laser. All but one patient had a good surgical outcome (i.e. tongue in mouth at rest). One patient subsequently required multiple laser procedures for recurrent macroglossia. CONCLUSION: Anterior tongue reduction can be a safe procedure, with limited post-operative morbidity, consistently resulting in good surgical outcomes and improvement in macroglossia symptoms. Speech development does not appear to be adversely affected.
