Nutrition Management in Children Less than 5 Years of Age with Glycogen Storage Disease Type I: Survey Results.

Background: Nutrition management for GSD Type I (GSDI; OMIM #232200, 232220) is complex, with the goal being to maintain euglycemia while minimizing metabolic derangements. Management guidelines were published in 2002 and 2014. However, there is limited information on the nuances of nutrition management and the unique feeding challenges of children. Methods: A REDCap survey focusing on staffing and current practices in the nutrition management of children with GSD I who were <5 years of age was sent to the metabolic dietitian's listserv and GMDI membership in 8/2023. Results: There were 21 North American respondents. In 17/21 clinics (81%), Prosobee® was the primary choice for infant formula. Dietitians used different methods to determine hourly glucose needs. Fasting recommendations ranged from 1 to 3 h, and the use of nighttime continuous feeding was common. Cornstarch was started between 6 and 12 months of age. Most clinics did not use Glycosade® for children <5 years of age. Oral motor dysfunction, gagging, and lack of interest in food were common. Continuous glucose monitoring (CGM) devices were recommended in 20 clinics (95%). Most clinics followed patients on an outpatient basis. All clinics provided a hypoglycemia management plan; however, there was wide variability in practice. Conclusion: This survey highlights the variability in the care of individuals <5 years of age with GSD I. Updated guidelines are needed to help address the unique nutrition challenges in this age group.

Comparison of the prevalence of malocclusion and oral habits between children with cerebral palsy and healthy children

BackgroundCerebral palsy (CP) represents for children an important problem of health and affects roughly 2 per 1000 live births and is the most common pediatric developmental motor disability. Therefore, the purpose of this study was to determine the prevalence, type and severity of malocclusion and oral habits in children with Cerebral Palsy (CP) and to compare them with a control group of healthy children in Sana’a city.Materials and methodsA prospective, case–control study was made of two groups, a cerebral palsy and a control group. The study population consisted of 60 children who had CP, and a control group of 60 matched children with no physical or mental disabilities. Data were collected using a questionnaire and assessment for malocclusion was done clinically. The patients were compared with equal number of age-matched controls. The inclusion criteria were individuals aged over 6 years; absence of previous orthodontic treatment; no missing permanent first molars.ResultsResults showed an increased prevalence of malocclusion in children with cerebral palsy. Molar class II relationship was statistically higher in cerebral palsy children than healthy control (P = 0.001). Cerebral palsied children are likely to have a significantly increased protrusion of the anterior teeth (P < 0.001) when compared with normal children. Mouth breathing and Tongue thrust. Habits were significantly higher in the CP group (p = 0.0001) when compared with normal children.ConclusionThe prevalence of malocclusion was higher in children with Cerebral palsy than in normal children, and the present study concludes that in children with Cerebral Palsy, more oral Habits problems due to oral motor dysfunctions are common and problems of mouth breathing and Tongue thrust produce different malocclusion and poor oral hygiene complications in these children.

Comparison of the introduction of consistencies in complementary feeding introduction between preterm and full-term newborns - Cohort from 0 to 12 months.

To compare the introduction of consistencies during the period of complementary feeding of preterm and full-term newborns up to 12 months of life, as well as to evaluate the presence of oral motor dysfunction and its relation to difficulty in introducing food consistencies in these groups. This is an observational, analytical, cohort study, with ambispective data collection, carried out at the Municipal Department of Health of Mafra, state of Santa Catarina, Brazil. The study sample consisted of 87 newborns, 41 full-term and 46 preterm. While data was collected, interviews were held with the mothers/guardians. The anthropometric assessment was carried out by a nutritionist by measuring body weight, length, and head circumference, followed by assessment of oral and functional motor skills by the adapted Clinical Evaluation Protocol of Pediatric Dysphagia (PAD-PED), assessment of breastfeeding and neuropsychomotor development, and assessment of the presence of maternal depression and psychological risk of children with up to 12 months of corrected age. We verified oral motor dysfunction in 15 newborns, in both groups, in the liquid consistency in the first assessment, persisting in two cases in the full-term newborns and in three cases in the preterm infants, in the last assessment for the solid consistency. We observed no difference in the introduction of food consistencies between groups. Breastfeeding was more frequent in newborns in the first assessment and similar in other assessments. Regarding the predictors for oral motor dysfunction, bottle feeding increased the odds by about seven times and invasive oral procedures by about six times.

Oromotor rehabilitation on drooling and feeding activities in children with cerebral palsy: A case study

Abstract: Cerebral palsy (CP) is a neurological disorder that affects the brain and causes difficulties with muscle coordination, body movement, and balance. Children with CP frequently present with severe oral motor impairments. Children with CP suffer from a variety of motor disorders, which are frequently accompanied by sensory, cognitive, communication, perception, and behavioral disorders, as well as epilepsy, nutrition, dysphagia, and oral motor dysfunction. CP refers to a group of long-term movement and posture impairments that occur in the developing infant brain, limiting many activities such as independent walking, stair climbing, running, or walking on an uneven surface. The purpose of this case report is to describe the difficulty in oromotor functional activity experienced by a CP child. A 5-year-10-month-old baby presented with drooling and difficulty in feeding activities, which greatly affected her day-to-day activities. Her pediatric Ability for Basic Feeding and Swallowing in Children-10 (ABFS-C) was 6/15 and The Drooling Impact Scale (DIS) 72/100 total score improved to (DIS) 83/100 and (ABFS-C) 10/15.

Minimally Invasive Approach to Access Vessels for Microvascular Anastomosis in Head and Neck Reconstruction.

To describe our technique, review indications, and evaluate the outcomes of the minimal access approach for recipient vessel identification in microvascular tissue transfer. Retrospective chart review of all patients who underwent microvascular reconstruction using the minimal access technique between 2015 and 2021. We report 236 cases, comprising 214 patients with a mean age of 60.2 years (3-88). The most common primary defect sites were the mandible (22.6%), cranium (14%), maxilla (13.2%), skull base (12.8%), and nose/nasal cavity (10.6%). Indications for free flap reconstruction included head and neck cancer extirpation (32.2%), osteoradionecrosis (29.7%), acquired deformity (14.0%), chronic wound (11.9%) and oral motor dysfunction (7.2%). Free flap donor sites used were the anterolateral thigh (84.3%), fibula (7.2%), and radial forearm (6.4%). Vessels utilized include superficial temporal (49.8%), facial (38.3%), angular (11.1%), and transverse cervical (0.4%). The overall complication rate was 14% (n = 33), with surgical complications at the recipient site accounting for 67.6% (n = 25). Flap failure occurred in 3.4% of procedures. Prior head and neck surgery and free flaps were associated with an increased risk of major recipient site complications (n = 20, p = 0.0257 and n = 14, p = 0.0117, respectively). Minimal access techniques allow consistent recipient vessel identification for microvascular-free tissue transfer. These approaches may be utilized in reconstructing a broad range of head and neck defects, are low morbidity, and contribute to an overall shorter length of stay. 2 Laryngoscope, 134:2177-2181, 2024.

Fiberoptic Endoscopic Evaluation of Swallowing Findings in Children With Rett Syndrome.

Feeding abnormalities, swallowing dysfunction, and gastrointestinal issues cause poor weight gain, oral motor dysfunction, and air swallowing in children with Rett syndrome (RTT). Pneumonia is the leading cause of death. Our study describes fiberoptic endoscopic swallowing findings in 11 female RTT children. Each patient was evaluated using the 8-point Penetration/Aspiration Scale (PAS). The average age was 7 years. All patients had tongue dyskinesis and prolonged oral stage. Eight girls exhibited liquid entering the airway without coughing, whereas 6 did well with pureed meal. Three girls had pneumonia. Age was not correlated with pneumonia episodes (P = .18). Pureed material was related with pneumonia (P = .006), whereas liquids were not. Pureed PAS was positively correlated with Liquid PAS (P = .008) and age (P = .004). All aspiration/penetration incidents occurred before the pharyngeal phase. No patient under 7 years experienced pneumonia episodes. Silent aspiration can occur early in infancy, although pneumonia episodes can occur later.

DYSPHAGIA IN CHILDREN WITH CEREBRAL PALSY AND THE ROLE OF FIBEROPTIC ENDOSCOPIC EVALUATION OF SWALLOWING (FEES): A REVIEW

Background: Cerebral palsy (CP) is a neurological disorder that affects muscle control and coordination, often resulting in various physical and developmental challenges. Dysphagia poses a common challenge in children diagnosed with cerebral palsy, significantly impacting their ability to eat and swallow. The mechanisms of dysphagia in children with cerebral palsy can be multifactorial and involve several factors, including oral motor dysfunction, decreased muscle tone, gastroesophageal reflux, delayed or disorganized swallowing reflexes, sensory issues, and structural abnormalities. Accurate assessment of dysphagia is vital for effective management. Aim: This comprehensive review aims to provide a thorough explanation of dysphagia in pediatric CP, with a particular focus on the application of Fiberoptic Endoscopic Evaluation of Swallowing (FEES) as an evaluative tool. Method: A comprehensive search strategy was utilized to locate relevant studies from databases including PubMed Medline, Cochrane, Embase, Proquest, dan Scopus. Results: In cerebral palsy-related dysphagia, disruptions in muscle coordination and control during swallowing can result in significant complications. Early detection and intervention are vital to minimize adverse outcomes. FEES is a safe outpatient procedure used to assess swallowing in this condition, with abnormal findings including delayed swallow initiation, reduced tongue control and bolus manipulation, impaired velopharyngeal closure, reduced laryngeal elevation and closure, decreased epiglottic movement, pharyngeal residue, and signs of penetration or aspiration. Conclusion: Overall, FEES offers valuable insights into the swallowing function of these children and helps guide appropriate treatment interventions Keywords: dysphagia; FEES; children; cerebral palsy

Factors Related to Oral Problems in Patients with Prolonged Disorders of Consciousness in Long-Term Care: A Cross-Sectional Study.

Factors influencing oral problems, such as malocclusion and oral motor dysfunction, in patients with prolonged disorders of consciousness (DOC) remain unclear. This study aimed to clarify the relationship between oral problems and physical function, communication, respiration, and oral intake status, as well as related factors in patients with DOC receiving long-term care at home. A cross-sectional study was conducted in October 2018; 127 patients who developed DOC > 5 years ago were analyzed. The differences between patients with and without oral problems were examined, and a binomial logistic regression analysis was performed to examine factors associated with oral problems, with the presence of oral problems as the dependent variable, and age, the number of years since onset, drooling, oral intake status, and the presence of a family dentist as explanatory variables. A post hoc power analysis of the binomial logistic regression analysis for oral problems (odds ratio: 2.05, alpha value: 0.05, incidence of oral problems: 0.80, and total sample size: 127) demonstrated an observed power of 93.09%. Oral intake status (p = 0.010) and the number of years since onset (p = 0.046) were significantly related to oral problems. Preventive oral management and rehabilitation from the early stage after onset may be effective for oral problems in patients with DOC.

CHARACTERISTICS OF COOPERATIVE WORK OF THE PEDAGOGICAL-PSYCHOLOGICAL GROUP IN THE PROCESS OF OVERCOMING ORAL-MOTOR DYSFUNCTION

The study aimed to describe the characteristics of cooperation among the pedagogical-psychological group members while dealing with the issues of oral-motor dysfunction. The research was conducted using a qualitative methodology. A semi-structured interview method was used for data collection with speech therapists, psychologists and occupational therapists (in total 6 specialists) to highlight the features of group work cooperation in the process of overcoming oral-motor problems. The analysis of the research data was carried out based on the descriptive method. The results of the research proved that during oral-motor dysfunction, the implementation of joint and mutually agreed activities, preliminary discussions of rehabilitation intervention planning and the ways of its implementation, and synchronizing the main approaches used by different professionals were important prerequisites for the cooperative work among the pedagogical-psychological group members. In addition, the desire of specialists to collaborate, the need to use complementary approaches and the planning of systematic group work discussions also determined the effectiveness of the rehabilitation process and ensured a positive result.

What to Expect of Feeding Abilities and Nutritional Aspects in Achondroplasia Patients: A Narrative Review.

Achondroplasia is an autosomal dominant genetic disease representing the most common form of human skeletal dysplasia: almost all individuals with achondroplasia have identifiable mutations in the fibroblast growth factor receptor type 3 (FGFR3) gene. The cardinal features of this condition and its inheritance have been well-established, but the occurrence of feeding and nutritional complications has received little prominence. In infancy, the presence of floppiness and neurological injury due to foramen magnum stenosis may impair the feeding function of a newborn with achondroplasia. Along with growth, the optimal development of feeding skills may be affected by variable interactions between midface hypoplasia, sleep apnea disturbance, and structural anomalies. Anterior open bite, prognathic mandible, retrognathic maxilla, and relative macroglossia may adversely impact masticatory and respiratory functions. Independence during mealtimes in achondroplasia is usually achieved later than peers. Early supervision of nutritional intake should proceed into adolescence and adulthood because of the increased risk of obesity and respiratory problems and their resulting sequelae. Due to the multisystem involvement, oral motor dysfunction, nutrition, and gastrointestinal issues require special attention and personalized management to facilitate optimal outcomes, especially because of the novel therapeutic options in achondroplasia, which could alter the progression of this rare disease.

Influence of eating habits of children with Autistic Spectrum Disorder (ASD)

Children with ASD are more likely to have eating difficulties, such as refusing and choosing certain foods, oral motor dysfunction and various behavioral problems. In addition, they may have essential micronutrient deficiencies compared to other children in the same developmental range. To verify the eating habits of children with Autism Spectrum Disorder (ASD). An integrative review was carried out based on the PICo strategy. The search for articles was carried out in the PubMed, Scielo, Lilacs databases, using the descriptors in Portuguese and English: “Food selectivity”, “Habits” and “Autistic spectrum disorder” joined with the Boolean operator “AND”. Access to the databases was carried out from February to April 2022. 185 articles were found and after applying the inclusion criteria, 12 articles remained. It was noticed that children with Autism Spectrum Disorder (ASD) have a predisposition to food selectivity behaviors, which can indicate nutritional problems, a worrying factor, given that the childhood stage has a direct long-term influence. It is necessary that these children receive adequate intervention with regard to nutritional monitoring. The main eating habits in children with Autism Spectrum Disorder (ASD) are behaviors of food selectivity, resistance to trying new foods, reading variation, behavioral problems at mealtimes, where such food preferences are attributed to the influence of other factors, such as sensory sensitivity and family diet.

Oral colonization of Acinetobacter baumannii in intensive care units: Risk factors, incidence, molecular epidemiology, association with the occur of pneumonia and sepsis, and infection control measures.

Objective(s):Oral colonization of Acinetobacter baumannii can lead to infections such as pneumonia and sepsis. We aimed to evaluate oral colonization of hospitalized patients in ICUs and to examine risk factors for oral colonization, molecular epidemiology, and incidence of pneumonia and sepsis. Materials and Methods:The study began in February 2021. Oral cultures were taken. The microorganisms were identified by a Maldi-tof MS mass spectrometry device. Colistin resistance genes were investigated by polymerase chain reaction. Clonal relationships were determined by pulsed-field gel electrophoresis. Results: A. baumannii was found in 21 of 96 patients’ oral cultures. Pneumonia and sepsis due to A. baumannii were detected in 14 and 5 patients, respectively. The mean growth time of A. baumannii from oral cultures was 11.8 days, and the meantime for the occurrence of pneumonia after oral growth was 5.2 days. We determined a plasmid mediated mcr-2 colistin resistance gene in a colistin susceptible A. baumannii strain. It is the first report of the plasmid mediated mcr-2 colistin resistance gene in our country. In total, fourteen different A. baumannii genotypes were determined in PFGE. It was determined that the effects of antibiotic use, oral motor dysfunction, mechanical ventilation, intubation, orogastric tube use, and total parenteral nutrition intake on oral colonization were statistically significant.Conclusion:Oral colonization of A. baumannii is a significant concern in ICUs. We believe that it is important to take oral cultures and follow the risk factors and take infection control measures to prevent oral colonization of resistant isolates in ICUs.

Electroencephalogram Background Predicts Time to Full Oral Feedings in Hypoxic-Ischemic Encephalopathy.

Infants with a history of neonatal hypoxic-ischemic encephalopathy (HIE) are at risk for oral motor dysfunction. Previous studies have associated the need for gastrostomy tube at neonatal intensive care unit discharge with brainstem injury on magnetic resonance imaging (MRI). However, the factors associated with time to full oral feeds in this population have not been previously described. This study aimed to study factors associated with time to full oral feeds in this population. This is a single-center, retrospective study that examined these factors using Cox regression. A total of 150 infants who received therapeutic hypothermia from 2011 to 2017 were included in this study. The single clinical factor significantly associated with time to full oral feeds was the severity of background abnormality on electroencephalogram in the first 24 hours of age (severe vs. mild 95% confidence interval [CI]: 0.34-0.74; moderate vs. mild 95% CI: 0.19-0.45). Brainstem injury on MRI was the factor most highly associated with need for gastrostomy tube placement (p = 0.028), though the overall incidence of need for gastrostomy tube feeds in this population was low (5%). These findings may help clinicians counsel families on what to expect in neonates with HIE and make decisions on the need for and timing to pursue gastrostomy tube in this population. · The overall incidence of the need for assisted feeding at NICU discharge is low in this population.. · MRI brainstem injury was most highly associated with need for gastrostomy tube placement.. · Worsening severity of background abnormality on EEG was associated with longer time to oral feeds..

Swallowing, Oral Motor, Motor Speech, and Language Impairments Following Acute Pediatric Ischemic Stroke.

Following adult stroke, dysphagia, dysarthria, and aphasia are common sequelae. Little is known about these impairments in pediatric stroke. We assessed frequencies, co-occurrence and associations of dysphagia, oral motor, motor speech, language impairment, and caregiver burden in pediatric stroke. Consecutive acute patients from term birth-18 years, hospitalized for arterial ischemic stroke (AIS), and cerebral sinovenous thrombosis, from January 2013 to November 2018 were included. Two raters reviewed patient charts to detect documentation of in-hospital dysphagia, oral motor dysfunction, motor speech and language impairment, and caregiver burden, using a priori operational definitions for notation and assessment findings. Other variables abstracted included demographics, preexisting conditions, stroke characteristics, and discharge disposition. Impairment frequencies were obtained by univariate and bivariate analysis and associations by simple logistic regression. A total of 173 patients were stratified into neonates (N=67, mean age 2.9 days, 54 AIS, 15 cerebral sinovenous thrombosis) and children (N=106, mean age 6.5 years, 73 AIS, 35 cerebral sinovenous thrombosis). Derived frequencies of impairments included dysphagia (39% neonates, 41% children); oral motor (6% neonates, 41% children); motor speech (37% children); and language (31% children). Common overlapping impairments included oral motor and motor speech (24%) and dysphagia and motor speech (23%) in children. Associations were found only in children between stroke type (AIS over cerebral sinovenous thrombosis) and AIS severity (more severe deficit at presentation) for all impairments except feeding impairment alone. Caregiver burden was present in 58% patients. For the first time, we systematically report the frequencies and associations of dysphagia, oral motor, motor speech, and language impairment during acute presentation of pediatric stroke, ranging from 30% to 40% for each impairment. Further research is needed to determine long-term effects of these impairments and to design standardized age-specific assessment protocols for early recognition following stroke.

Orofacial pain in 1916 patients with early or moderate Parkinson disease.

Several studies have reported that some types of orofacial pain are more common in patients with Parkinson disease (PD) than the general population. In this study, we aimed to investigate the prevalence of self-reported orofacial pain in a larger group of patients with PD than has been previously studied. We analysed data from 1916 participants with PD in a cross-sectional study recruited to the UK Parkinson's Pain Study who had detailed assessments of pain, motor, and nonmotor symptoms. The King's Parkinson's Pain scale was used to quantify different subtypes of pain. A total of 139 (7.3%) patients reported the presence of some form of orofacial pain. Burning mouth syndrome was reported in 32 (1.7%), whereas chewing pain was found in 38 (2.0%) and grinding pain in 78 (4.0%). Orofacial pain was significantly more common in females (10.4%) than males (5.9%). Multiple logistic regression analysis showed a significant association between orofacial pain and pain severity, neuropathic pain, and oral motor and nonmotor dysfunction. In our study, population cohort of early patients with PD found prevalence of orofacial pain conditions similar to that in the general population.

Dependence Of Protein-Energy Insufficiency On The Degree Of Motor Disorders In Infantile Cerebral Palsy

Purpose of research. To assess the impact of the severity of motor disorders in children with cerebral palsy on nutritional status. Materials and methods of research. The study included 102 children with cerebral palsy aged 2 to 17 years, 60 boys (58.8%) and 42 girls (41.2%). The average age of the children was 7.23 ± 4.9 years. Patients were ranked by age group in accordance with the age classification of the GMFCS scale. All children underwent a comprehensive clinical and neurological examination, nutritional status assessment, and anthropometry (measurement of shoulder circumference and plicometry). During anthropometry, the control group included 30 healthy children with an average age of 7.7±4.2 years. Results. It was found that with an increase in the severity of motor disorders, the number of children with protein-energy deficiency increases from 50% at level I to 100% at level V on the GMFCS scale (the significance of differences in Pearson's Chi-square was confirmed statistically: 9.32, p = 0.002069). At the same time, a severe degree of protein-energy insufficiency was observed mainly in double hemiplegia (amounting to 40.9%). Prognostically, cerebral palsy was the most favorable type of spastic hemiparesis and spastic diplegia, with a predominance of protein-energy insufficiency of a mild degree, amounting to 45.8% and 60%, respectively. In 71.6% of cases (n=73), children with cerebral palsy were diagnosed with oral-motor dysfunction of varying severity, problems with food consumption and, as a result, a noticeable lag in anabolic processes. Statistically significant differences were found in the frequency of feeding difficulties in children with levels I and V of motor abilities (Pearson's Chi-square: 20.12, p = 0.000005).

Risk factors of malnutrition in children with severe motor and intellectual disabilities

BackgroundChildren with severe motor and intellectual disabilities (SMID) are at a high risk of malnutrition and often require tube feeding to maintain their nutritional status. However, determining their energy requirements is difficult since inadequate dietary intake, severe neurological impairment, respiratory assistance, and cognitive impairment are all factors that affect malnutrition in SMID. AimThis study investigated the factors affecting malnutrition and identified problems affecting the nutritional status of children with SMID. MethodsForty-two children with SMID with oral motor dysfunction who were receiving home medical care at one of four hospitals were enrolled. Their nutritional status was assessed using a 3-day dietary record, anthropometric measurements, and laboratory tests. The clinical findings associated with malnutrition were compared, and a body mass index (BMI) z-score less than −2SD was defined as malnutrition. The relationship between BMI z-score and other potential predictors was also investigated. ResultsThirty-three (79%) children received tube feeding, and 20 (48%) experienced malnutrition. The median age of the malnourished children was older than that of non-malnourished children. Respiratory assistance was significantly correlated with higher BMI z-score, independent of other potential confounders such as nutrition method, muscle tonus, and energy intake. Cholesterol levels were significantly higher in children receiving a standard infant formula beyond 3 years of age than in those who switched to enteral formula before 3 years of age. ConclusionsMalnutrition in children with SMID was mainly associated with age or respiratory condition. Energy requirements should be regularly re-evaluated with considering these factors.

Feeding characteristics of infants in a lower-middle-income country.

To describe feeding characteristics (such as breast feeding and complementary feeding) and determine the nature of feeding difficulties of infants in a primary health-care clinic (PHC) in South Africa. A total of 200 infants aged 6-12 months (mean = 8.54, standard deviation = 2.18) received a feeding screening by a speech-language therapist at a PHC in a semi-urban area using the Montreal Children's Hospital-Feeding Scale (MCH-FS). Children who failed screening underwent further clinical feeding evaluation using the Schedule of Oral Motor Assessment. The sample consisted of 200 participants, and most participants (n = 174; 87%) received breastfeeding, irrespective of their mothers' human immunodeficiency virus status. The longer the breastfeeding period, the less likely parents were to show concern about infants' feeding (P = 0.035). Complementary feeding was introduced between 6 and 8 months (n = 122; 82%). The MCH-FS identified 13 participants with feeding difficulties (6.5%), of which 11 were diagnosed with oral motor dysfunction (OMD) using the Schedule of Oral Motor Assessment. The 6.5% (n = 13) that failed had mild (n = 8; 61.5%), moderate (n = 2; 15.4%) and severe (n = 3; 23.1%) feeding difficulties, as reported by care givers using the MCH-FS. The MCH-FS showed that distraction during meals/following infants (n = 42; 21%); food refusal (n = 31; 15.5%); care giver unease about feeding (n = 29; 14.5%); and problems with vomiting, gagging or spitting (n = 28; 14%) were characteristics of feeding in this sample. Participants in the age groups 6 (n = 3; 27.3%) and 10 months (n = 3; 27.3%) were prone to OMD. This study is the first of its kind to describe the feeding characteristics of a group of infants during the transitional feeding stage in late infancy in South Africa. Important findings were the existence of OMD in 11 infants and feeding difficulties during transitional feeding in 13 infants. The study's findings may be used as a starting point for larger-scale studies in a similar setting, investigating the development of future care giver education and health-care professional training programmes regarding transitional feeding. Research endeavours by speech-language therapists need to prioritise late infancy and transitional feeding in order to prevent possible difficulties arising from sub-optimal care giver feeding practices. The study may be valuable to all health-care providers in PHC.

Surface Electromyographic Analysis of the Suprahyoid Muscles in Infants Based on Lingual Frenulum Attachment during Breastfeeding.

Muscle electrical activity analysis can aid in the identification of oral motor dysfunctions, such as those resulting from an altered lingual frenulum, which consequently impairs feeding. Here, we aim to analyze the suprahyoid muscle electrical activity of infants via surface electromyography, based on lingual frenulum attachment to the sublingual aspect of the tongue and floor of the mouth during breastfeeding. In the present study, we have studied full-term infants of both genders, aged between 1 and 4 months old. The mean muscle activities were recorded in microvolts and converted into percent values of the reference value. Associations between the root mean square and independent variables were tested by one-way analysis of variance and Student’s t-test, with a significance level of 5% and test power of 95%, respectively. We evaluated 235 infants. Lower mean muscle electrical activity was observed with the lingual frenulum attached to apex/lower alveolar ridge, followed by attachment to the middle third/lower alveolar ridge, and between the middle third and apex/lower alveolar ridge. Greater suprahyoid muscle activity was observed with lingual frenulum attachment to the middle third of the tongue/sublingual caruncles, showing a coordination between swallowing, sucking, and breathing. Surface electromyography is effective in diagnosing lingual frenulum alterations, the attachment points of which raises doubt concerning the restriction of tongue mobility. Thus, it is possible to identify oral motor dysfunctions.
