Abstract
Sanfilippo syndrome is a group of rare, complex, and progressive neurodegenerative lysosomal storage disorders that is characterized by childhood dementia. The clinical management of patients with progressive neurological decline and multisystem involvement requires a multidisciplinary team with experience in the management of neurodegenerative disorders. Best practice guidelines for the clinical management of patients with these types of rare disorders are critical to ensure prompt diagnosis and initiation of appropriate care. However, there are no published standard global clinical care guidelines for patients with Sanfilippo syndrome. To address this, a literature review was conducted to evaluate the current evidence base and to identify evidence gaps. The findings were reviewed by an international steering committee composed of clinical experts with extensive experience in managing patients with Sanfilippo syndrome. The goal was to create a consensus set of basic clinical guidelines that will be accessible to and informed by clinicians globally, as well as providing a practical resource for families to share with their local care team who may not have experience with this rare disease. This review distills 178 guideline statements into an easily digestible document that provides evidence-based, expert-led recommendations for how to approach common management challenges and appropriate monitoring schedules in the care of patients with Sanfilippo syndrome.

Abstract
Sanfilippo Syndrome, or mucopolysaccharidosis type III (MPS III), is a group of autosomal-recessive lysosomal storage disorders leading to tissue accumulation of heparan sulfate. MPS III is caused by deficiency in one of 4 enzymes involved in lysosomal degradation of heparan sulfate. Based on the relevant enzyme deficiency, 4 types have been recognized. MPS III constitutes a progressive neurodegenerative and systemic disorder. Parents of children diagnosed with MPS III were interviewed using a retrospective questionnaire based on the known clinical manifestations of MPS III. Eight patients from 4 unrelated families of varied ethnic origin were included. All children were diagnosed with MPS type III-A. Average age at diagnosis was 6.1 years. The most common early clinical manifestations leading to parental suspicion of illness were speech delay and coarse facial features. All children were reported to have global developmental delay, sleep disorders, recurrent infections, hyperactivity, and decreased hearing. The time from first medical inquiry until diagnosis was over 2 years on average, consistent with the delay in diagnosis described in the literature. MPS III children frequently undergo early and repeated ear, nose and throat surgeries, thus we suggest that a high index of suspicion is warranted in relevant clinical circumstances.

Abstract
Introduction Mucopolysaccharidosis type III (MPS III) or Sanfilippo syndrome is a neurodegenerative disease caused by the accumulation of mucopolysaccharides in the body. As the symptoms are wide ranging, it is a challenge to provide a diagnosis and psychological treatment for affected children. Method The main objective of this study was to describe a form of music therapy treatment applied to three children diagnosed with MPS III. The psychological variables were evaluated by an ad hoc observation recording template, and the physiological variables were measured with a digital meter before and after each session. The perception of the parents was also considered through a semi-structured interview. Results An improvement in the psychological variables was shown in all cases. Changes in the physiological variables were also noted, although they varied according to each child. The parents report some benefit of music therapy and they share difficulty in assessing the extent of benefits of the music therapy. Discussion Findings indicate that music therapy can be a useful form of treatment with multiple benefits for children with conditions such as MPS III or similar conditions. However, further research is needed in this area and in the development of specific ways of evaluating music therapy.

Abstract
Airway management in patients suffering from mucopolysaccharidoses (MPS) is one of the most difficult anesthesiologic challenges. MPS is a group of rare, inherited diseases caused by the absence or malfunctioning of lysosomal enzymes needed to break down macromolecules called glycosaminoglycans (GAGs). MPS is associated with clinical symptoms and physical features, which all together contribute to the high incidence of difficulty in providing airway during surgical procedures. We used PubMed as our main database (PubMed Advanced Search Builder) to search for relevant literature. At first, we looked for the prevalence of MPS worldwide. Then, we searched for airway management complications in the MPS population using the keywords: “Mucopolysaccharidoses,” “Anesthesia complications,” and “airway management.” Another search was carried out to look for new therapeutic agents and explore their impacts on body organs. We reviewed the finalized articles to explore how anesthesiologists used different airway techniques. We discovered that video laryngoscope and I-gel aided fiber-optic intubation have been available in recent years and have been used uneventfully in several patients. We presented recommendations regarding preoperative and intraoperative preparation to avoid airway-related complications in the future. We realized that many therapy approaches had been suggested, especially after further understanding of the pathophysiology of MPS. However, more investigation needs to be conducted to determine their efficacy and explore if there is any impact on airway management.

A retrospective comparison of propofol to dexmedetomidine for pediatric magnetic resonance imaging sedation in patients with mucopolysaccharidosis type II. Paediatr Anaesth 2018; 28:1116-1122. [PMID: 30375140 DOI: 10.1111/pan.13514] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2018] [Revised: 09/06/2018] [Accepted: 09/17/2018] [Indexed: 01/21/2023]
Abstract
BACKGROUND Mucopolysaccharidosis type II patients are reported to have an elevated incidence of difficult airway. Propofol is a commonly used sedative for magnetic resonance imaging in pediatric patients, but patients who receive it may exhibit dose-dependent upper airway obstruction and respiratory depression. Dexmedetomidine also provides adequate procedural sedation with a relatively low risk of airway obstruction. Accordingly, we introduced the use of dexmedetomidine in our practice to reduce the risk of airway obstruction during magnetic resonance imaging procedures. AIMS The aim of this study was to evaluate the incidence of artificial airway interventions in patients sedated with propofol and compare it to that in patients sedated with dexmedetomidine in patients with mucopolysaccharidosis type II during magnetic resonance imaging procedures. METHODS All mucopolysaccharidosis type II patients undergoing magnetic resonance imaging at our institution between April 2014 and February 2018 were included in this study. The patients were divided into two groups according to whether they were managed before and after the introduction of dexmedetomidine: those who were sedated with propofol (group P) and those who were sedated with dexmedetomidine (group D). RESULTS Forty-six sedations were performed in 27 patients. Artificial airway interventions were significantly more frequent during propofol-based than dexmedetomidine-based sedation: 14 of 32 (43.8%) in group P and 1 of 14 (7.1%) in group D (odds ratio, 10.11; 95% confidence interval, 1.18-86.85; P = 0.018). Time to awake and time to discharge were similar between groups. Changes in hemodynamic variables also did not significantly differ between groups. CONCLUSION Dexmedetomidine provides an adequate level of sedation and is associated with lower rates of artificial airway interventions compared to propofol. Therefore, dexmedetomidine may offer advantages for preserving the native airway compared to propofol when administered during magnetic resonance imaging scans in patients with mucopolysaccharidosis type II.

Abstract
Background Patients suffering from mucopolysaccharidosis are among the most complex from the anesthesiological point of view, especially regarding the management of the airway. The evidence base for anesthesia management is often limited to case reports and small case series. Aims To identify useful information about experience with each subtype of mucopolysaccharidosis reported in the literature and propose a guide on the best options for airway management to the anesthesiologists who take care of these patients. Methods A query of the PubMed database specific for “anesthesia” and “mucopolysaccharidosis” and a further query specific for “mucopolysaccharidosis and difficult airway management” was conducted. We looked for those items that offered practical guidance to anesthesiological management. We did not exclude case reports, especially those that reported a specific technique, because of their practical suggestions. Results We identified 15 reviews, 17 retrospective case series, 5 prospective studies, and 28 case reports that focused on airway managements in anesthesia or had practical suggestions for preoperative evaluation and risk assessment. An accurate preoperative evaluation and the need for an experienced team are emphasized in all the reviewed articles and for each type of mucopolysaccharidosis. Many suggestions on how to plan the perioperative period have been highlighted. Insertion of a laryngeal mask airway generally improves ventilation and facilitates intubation with a fiberoptic bronchoscope. Furthermore, the videolaryngoscope is very useful in making intubation easier and facilitating bronchoscope passage. Conclusions Patients with mucopolysaccharidosis are at high risk for anesthesia-related complications and require a high level of attention. However, a multidisciplinary approach, combined with expertise in the use of new techniques and new devices for airway management, makes anesthesiological management safer. Further research with prospective studies would be useful.

Abstract
Mucopolysaccharidoses (MPS) are rare, inherited, lysosomal storage diseases that cause accumulation of glycosaminoglycans, resulting in anatomic abnormalities and organ dysfunction that can increase the risk of anesthesia complications. We conducted a systematic review of the literature in order to describe the anesthetic management and perioperative outcomes in patients with MPS. We reviewed English-language literature search using an OVID-based search strategy of the following databases: 1) PubMed (1946-present), 2) Medline (1946-present), 3) EMBASE (1946-present), and 4) Web of Science (1946-present), using the following search terms: mucopolysaccharidosis, Hurler, Scheie, Sanfilippo, Morquio, Maroteaux, anesthesia, perioperative, intubation, respiratory insufficiency, and airway. The review of the literature revealed nine case series and 27 case reports. A substantial number of patients have facial and oral abnormalities posing various challenges for airway management, however, evolving new technologies that include videolaryngoscopy appears to substantially facilitate airway management in these patients. The only type of MPS that appears to have less difficulty with airway management are MPS III patients, as the primary site of glycosaminoglycan deposition is in the central nervous system. All other MPS types have facial and oral characteristics that increase the risk of airway management. To mitigate these risks, anesthesia should be conducted by experienced anesthesiologists with expertise in using of advanced airway intubating devices.
