Differences in analysis and treatment of upper airway obstruction in Robin sequence across different countries in Europe. Eur J Pediatr 2023; 182:1271-1280. [PMID: 36633656 DOI: 10.1007/s00431-022-04781-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/19/2022] [Accepted: 12/21/2022] [Indexed: 01/13/2023]
Abstract
The goal of this study was to explore the availability of diagnostic and treatment options for managing upper airway obstruction (UAO) in infants with Robin Sequence (RS) in Europe. Countries were divided in lower- (LHECs, i.e., PPP per capita < $4000) and higher-health expenditure countries (HHECs, i.e., PPP per capita ≥ $4000). An online survey was sent to European healthcare professionals who treat RS. The survey was designed to determine the availability of diagnostic tools such as arterial blood gas analysis (ABG), pulse oximetry, CO2 analysis, polysomnography (PSG), and sleep questionnaires, as well as to identify the used treatment options in a specific center. Responses were received from professionals of 85 centers, originating from 31 different countries. It was equally challenging to provide care for infants with RS in both LHECs and HHECs (3.67/10 versus 2.65/10, p = 0.45). Furthermore, in the LHECs, there was less access to ABG (85% versus 98%, p = 0.03), CO2 analysis (45% versus 70%, p = 0.03), and PSG (54% versus 93%, p < 0.01). There were no significant differences in the accessibility concerning pulse oximetry, sleep questionnaires, home saturation monitoring, nasopharyngeal tubes, Tuebingen plates, and mandibular distraction. Conclusion: This study demonstrates a large difference in available care for infants with RS throughout Europe. LHECs have less access to diagnostic tools in RS when compared to HHECs. There is, however, no difference in the availability of treatment modalities between LHECs and HHECs. What is Known: • Patients with Robin sequence (RS) require complex and multidisciplinary care. They can present with moderate to severe upper airway obstruction (UAO). There exists a large variety in the use of diagnostics for both UAO treatment indications and evaluations. In most cases, conservative management of UAO in RS is sufficient. Patients with UAO that persist despite conservative management ultimately need surgical intervention. To determine which intervention is best suitable for the individual RS patient, the level of UAO needs to be determined through diagnostic testing. • There is a substantial variation among institutions across Europe for both diagnostics and treatment options in UAO. A standardized, internationally accepted protocol for the assessment and management of UAO in RS could guide healthcare professionals in the timing of assessment and indications to prevent escalation of UAO. Creating such a protocol might be a challenge, as there are large financial differences between countries in Europe (e.g., health expenditure per capita in purchasing power parity in international dollars ranges from $600 to over $8500). What is New: • There is a substantial variation in the availability of objective diagnostic tools between European countries. Arterial blood gas analysis, CO2 analysis and polysomnography are not equally accessible for lower-healthcare expenditure countries (LHECs) compared to higher-healthcare expenditure countries (HHECs). These differences are not only limited to availability; there is also a difference in quality of these diagnostic tools. Surprisingly, there is no difference in access to treatment tools between LHECs and HHECs. • There is national heterogeneity in access to tools for diagnosis and treatment of RS, which suggests centralization of health care, showing that specialized care is only available in tertiary centers. By centralization of care for RS infants, diagnostics and treatment can be optimized in the best possible way to create a uniform European protocol and ultimately equal care across Europe. Learning what is necessary for adequate monitoring could lead to better allocation of resources, which is especially important in a low-resource setting.

Automation of Measurements for Personalized Medical Appliances by Means of CAD Software-Application in Robin Sequence Orthodontic Appliances. BIOENGINEERING (BASEL, SWITZERLAND) 2022; 9:bioengineering9120773. [PMID: 36550978 PMCID: PMC9774752 DOI: 10.3390/bioengineering9120773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/25/2022] [Accepted: 12/02/2022] [Indexed: 12/12/2022]
Abstract
Measuring the dimensions of personalized devices can provide relevant information for the production of future such devices used in various medical specialties. Difficulties with standardizing such measurement and obtaining high accuracy, alongside cost-intensive measuring methodologies, has dampened interest in this practice. This study presents a methodology for automatized measurements of personalized medical appliances of variable shape, in this case an orthodontic appliance known as Tübingen Palatal Plate (TPP). Parameters such as length, width and angle could help to standardize and improve its future use. A semi-automatic and custom-made program, based on Rhinoceros 7 and Grasshopper, was developed to measure the device (via an extraoral scanner digital file). The program has a user interface that allows the import of the desired part, where the user is able to select the necessary landmarks. From there, the program is able to process the digital file, calculate the necessary dimensions automatically and directly export all measurements into a document for further processing. In this way, a solution for reducing the time for measuring multiple dimensions and parts while reducing human error can be achieved.

Abstract
Mandibular distraction osteogenesis (MDO) and continuous positive airway pressure (CPAP) may each have a role in effectively treating tongue-based airway obstruction (TBAO) in Robin sequence (RS). This study describes longitudinal outcomes after treatment of TBAO with CPAP and/or MDO. Retrospective cohort study. Tertiary Pediatric Hospital. A total of 129 patients with RS treated with CPAP and/or MDO from 2009 to 2019 were reviewed. Subjects receiving baseline and at least one follow-up polysomnogram were included. 55 who underwent MDO ± CPAP and 9 who received CPAP-only treatment were included. Patient characteristics, feeding, and polysomnographic data were compared and generalized linear mixed modeling performed. Baseline obstructive apnea-hypopnea index (OAHI) was greater in the MDO-treated group (median x˜ = 33.7 [interquartile range: 26.5-54.5] than the CPAP-treated group (x˜ = 20.3[13.3-36.7], P ≤ .033). There was significant reduction in OAHI following treatment with CPAP and MDO modalities, P ≤ .001. SpO2 nadir after MDO was lower in syndromic (x˜ = 85.0[81.0-87.9] compared to nonsyndromic patients (x˜ = 88.4[86.8-90.5], P ≤ .005.) CPAP was utilized following MDO in 2/24 (8.3%) of nonsyndromic and 16/31 (51.6%) of syndromic subjects (P ≤ .001,) for a median duration of 414 days. Three patients (5%) underwent tracheostomy, all had MDO. Nasogastric tube feeding at hospital discharge was more common following MDO (44, 80%) than CPAP-only (4, 44.4%, P ≤ .036), but did not differ at 6-month follow-up (P ≥ .376). CPAP appears to effectively reduce obstructive apnea in patients with RS and moderate TBAO and be a useful adjunct in syndromic patients following MDO with improved but persistent obstruction.
