Digitomotography in children with oro-facial dysfunction (OFD, oro-facial myofunctional disorders) and childhood apraxia of speech (CAS).

BACKGROUND: Oro-facial dysfunctions (OFDs; oro-facial myofunctional disorders) in children and childhood apraxia of speech (CAS) often cause severe problems in articulation, chewing, swallowing and oral posture. OBJECTIVES: Pathognomonic symptoms could yet not be identified, but central problems in planning, programming, timing and automating oro-facial, as well as other fine motor skills, are assumed to be affected. METHODS: To investigate the nature of motor and coordinative deficits in OFD and CAS, digitomotography was applied. The testing focused on recording frequency, force, rhythm and regularity of the index finger including speeded and metronome tapping tasks. 25 children with OFD (7 girls and 18 boys, age 7.9 ± 2.3) and 5 children with CAS (0 girls and 5 boys, age 7.6 ± 2.3), and 31 healthy controls (12 girls and 19 boys, age 9.3 ± 2.2) were tested. Statistical significance was accepted at α = 0.05. ANOVA test, non-parametric Mann-Whitney U test, Kruskal-Wallis test and Spearman's rank correlation coefficient were used. RESULTS: Cross-sectional data revealed consistent significant differences between children with OFD and healthy controls concerning frequency, force, rhythm and regularity of index finger tapping. Individuals with CAS showed particularly low results. Tapping results correlated with disease burden. CONCLUSION: These findings support that underlying superordinated sensorimotor deficits exist. This may help phenotyping and influence diagnostical and therapeutical approaches.

[Effects of Bilingualism on Cognitive Functions in Early Childhood]. / Auswirkungen von Bilingualität auf kognitive Funktionen im Vorschulalter.

Effects of Bilingualism on Cognitive Functions in Early Childhood Studies have revealed advantages in cognitive functions among children with bilingualism. In this study we investigate cognitive functions in monolingual and bilingual preschool children taking socioeconomic status into account. The study population consists of 40 monolingual (German) children (Mage = 5.0 ± 0.4) and 23 bilingual (German/English) children (Mage = 5.1 ± 0.6). A neuropsychological test battery was conducted. The analyses revealed better performance for bilingual children. However, significant group differences were only found with respect to phonological short-term memory. Controlling for socioeconomic status, intelligence and balanced bilingualism, only slight advantages in cognitive performance were found for bilingual children. Due to high socioeconomic status in both groups, we suppose a ceiling effect. Children's development might be extensively promoted in upper class families and therefore bilingualism may not have additional impact on cognitive functions in these children.

Frontalis suspension surgery to treat patients with blepharospasm and eyelid opening apraxia: long-term results.

Blepharospasm may be accompanied by eyelid opening apraxia (EOA) reducing the efficacy of botulinum toxin (BT) therapy. The frontalis suspension operation (FSO) is then the only effective treatment option available. We want to report the first long-term results with FSO. We studied 15 patients with blepharospasm and EAO unresponsive to BT therapy (9 females, 6 males, age 61.9 ± 11.5 years). FSO was performed by applying 2 polytetrafluoroethylene threads (PTFE, Gore-Tex®) per eye connecting the frontalis muscle to the upper eye lid. Tension of the two carrés was set to produce a palpebral fissure width of 2-3 mm. Therapy outcome was monitored by a quality-of-life questionnaire (QoL-Q) and a self-assessment calendar reviewing postoperative days 0-9 (T1), 10-89 (T2), 90-179 (T3), 180-365 (T4), and >365 days (T5). Altogether, 40 FSO were performed. Postoperatively, all patients reported improved eyelid opening, 4 (27%) complete remission of symptoms. At T1, this improvement was 74.6 ± 26.4% on the self-assessment scale, after 1 year 68.2 ± 27.5%. Throughout the observation period (T1-T5), the improvement was 71.9 ± 25.6%. All 19 items on the QoL-Q (except for presence of involuntary eye lid closure) showed postoperative improvement. Adverse effects included circumscript upper eyelid haematomas, suture extrusion, suture granuloma, lacrimation, and infections. In all patients, BT therapy had to be continued to treat orbicularis oculi contractions. Our first long-term results demonstrate that FSO is a benign procedure producing robust and stable therapeutic effects on EOA in blepharospasm.

Cognitive functions in preschool children with specific language impairment.

OBJECTIVE: A growing body of research has focused on executive functions in children with specific language impairment (SLI). However, results show limited convergence, particularly in preschool age. The current neuropsychological study compared performance of cognitive functions focused on executive components and working memory in preschool children with SLI to typically developing controls. METHOD: Performance on the measures cognitive flexibility, inhibition, processing speed and phonological short-term memory was assessed. The monolingual, Caucasian study sample consisted of 30 children with SLI (Mage = 63.3 months, SD = 4.3 months) and 30 healthy controls (Mage = 62.2 months, SD = 3.7 months). Groups were matched for age and nonverbal IQ. Socioeconomic status of the participating families was included. RESULTS: Children with SLI had significantly poorer abilities of phonological short-term memory than matched controls. A tendency of poorer abilities in the SLI group was found for inhibition and processing speed. CONCLUSIONS: We confirmed phonological short-term memory to be a reliable marker of SLI in preschoolers. Our results do not give definite support for impaired executive function in SLI, possibly owing to limited sensitivity of test instruments in this age group. We argue for a standardization of executive function tests for research use.

Position paper of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery and the German Society of Phoniatrics and Pediatric Audiology - Current state of clinical and endoscopic diagnostics, evaluation, and therapy of swallowing disorders in children.

Swallowing disorders are frequent. The main concern is mortality due to aspiration-induced pneumonia and malnutrition. In addition, quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract, and sequelae of tumor treatment in the head and neck region are the main pathologic entities. Predominantly ENT physicians and phoniatricians are asked for diagnostics and therapy, and will coordinate the interdisciplinary treatment according to the endoscopic findings. A differentiated approach in history, diagnostics, and symptom-oriented treatment is necessary for these mostly complex disorders. Integration of non-medical staff such as speech therapists, physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over in close cooperation. In particular, an interdisciplinary cooperation with the staff of intensive care medicine is essential. The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists. Endoscopy is a medical service that is basically not delegable. Consequently, substitution of the physician is excluded.

Frontalis suspension surgery to treat patients with essential blepharospasm and apraxia of eyelid opening-technique and results.

INTRODUCTION: We describe the results of 15 patients suffering from essential blepharospasm with apraxia of eyelid opening who underwent frontalis suspension surgery. MATERIAL AND METHODS: Patients with apraxia of eyelid opening and unresponsive to botulinum toxin injections were studied. Bilateral frontalis suspension surgery was performed (sling operation) using polytetrafluoroethylene (Gore-Tex®) sutures. The patients reported the degree of improvement using a subjective rating scale to evaluate the benefit of the operation at two times after surgery (0-10 days and 180-360 days). RESULTS: The patients reported a high degree of subjective improvement. In the early postoperative period (0-10 days) the mean degree of subjective improvement was 74.6% (standard deviation (SD) 26.4%). At 180-360 days after surgery the mean improvement was 70.0% (SD 26.7%). Small hematomas of the upper lid occurred postoperatively in all patients. Other complications were suture extrusions (9.1%), suture granulomas (6.1%), lacrimation (5.0%) and local infections (7.5%). Postoperatively, all patients needed additional botulinum toxin injections for optimal outcome. CONCLUSION: Frontalis suspension surgery is a minimally invasive and effective treatment option for apraxia of eyelid opening in patients with essential blepharospasm unresponsive to botulinum toxin injections alone.

Minimally invasive application of botulinum toxin A in patients with idiopathic rhinitis.

BACKGROUND: Nasal hypersecretion due to idiopathic rhinitis can often not be treated sufficiently by conventional medication. Botulinum toxin A (BTA) has been injected into the nasal mucosa in patients with nasal hypersecretion with a reduction of rhinorrhea lasting for about 4 to 8 weeks. Since the nasal mucosa is well supplied with glands and vessels, the aim of this study was to find out if the distribution of BTA in the nasal mucosa and a reduction of nasal hypersecretion can also be reached by a minimally invasive application by sponges without an injection. METHODS: Patients were randomly divided into two groups. The effect of BTA (group A, C, D) or saline as placebo (group B) was investigated in 20 patients with idiopathic rhinitis by applying it with a sponge soaked with BTA (40 units each nostril) or saline. Subgroups C and D contained these patients of group A and B who did not improve in symptoms one week after the original treatment (either BTA or saline) who then received the alternative medication. Changes of symptoms (rhinorrhea, nasal obstruction) were scored by the patients in a four point scale and counted (consumption of tissues, sneezing) in a diary. The patients were followed up weeks 1, 2, 4, 8 and 12. RESULTS: There was a clear reduction of the amount of secretion in group A compared to group B, C and D. This did not correlate with the tissue consumption, which was comparably reduced in group A and B, but reduced less in group C and D. Sneezing was clearly reduced in group A but comparably unchanged in group B and C and increased in group D. Nasal congestion remained unchanged. CONCLUSION: In some patients with therapy-resistant idiopathic rhinitis BTA applied with a sponge is a long-lasting and minimal invasive therapy to reduce nasal hypersecretion.

Improvement of chronic facial pain and facial dyskinesia with the help of botulinum toxin application.

BACKGROUND: Facial pain syndromes can be very heterogeneous and need individual diagnosis and treatment. This report describes an interesting case of facial pain associated with eczema and an isolated dyskinesia of the lower facial muscles following dental surgery. Different aspects of the pain, spasms and the eczema will be discussed. CASE PRESENTATION: In this patient, persistent intense pain arose in the lower part of her face following a dental operation. The patient also exhibited dyskinesia of her caudal mimic musculature that was triggered by specific movements. Several attempts at therapy had been unsuccessful. We performed local injections of botulinum toxin type A (BTX-A) into the affected region of the patient's face. Pain relief was immediate following each set of botulinum toxin injections. The follow up time amounts 62 weeks. CONCLUSION: Botulinum toxin type A (BTX-A) can be a safe and effective therapy for certain forms of facial pain syndromes.

Neuronal nitric oxide synthase-immunoreactivity. A neuromodulating system independent of peripheral nasal gland denervation in guinea pig nasal mucosal tissue after treatment with botulinum toxin type A.

The influence of botulinum toxin type A (BTA) on cellular mechanisms has not been studied in much detail. Since nitric oxide (NO) is of increasing interest as a neuromodulator in the innervation of the nose, its localization was examined in the nasal mucosa of guinea pigs treated with BTA or saline. Neuronal nitric oxide synthase-immunoreactivity (nNOS-IR) was found around vessels and nasal glands. Immunoreactivity was seen in the respiratory epithelium, in the periost and the osteocytes of the turbinate bone. A distinct interindividual difference in the strength of nNOS-IR was obvious among the animals, but there was no difference in the strength of immunoreactivity between the animals treated with BTA or saline. NO might therefore contribute to the regulation of vascular tone, glandular function, respiratory epithelial cell function and bone metabolism. BTA does not seem to influence the processes regulated and modulated by NO. This may represent a benefit for the application of BTA.

Neuronal nitric oxide synthase immunoreactivity in the nasal mucosa of patients with idiopathic and allergic rhinitis.

The localization of neuronal nitric oxide synthase (nNOS) in the mucosa of the inferior and middle turbinates of 30 patients with and without allergic rhinitis was examined by immunohistochemical methods. Staining of paraffin sections from allergic and nonallergic patients revealed nNOS immunoreactivity (nNOS-IR) in the muscular layer of vessels, in the basal portion of submucosal glands and in the periost and the osteocytes of the turbinate bones. In contrast to earlier investigations, nNOS-IR was also seen in the nasal respiratory epithelium of allergic and nonallergic patients. The immunostaining of sections of submucosal glands from allergic patients was stronger than that of sections from patients with idiopathic rhinitis or patients with no nasal obstruction. The present result - nNOS-IR around glands is elevated in patients with allergic rhinitis - could indicate that this enzyme is involved in the pathogenesis and symptomatology of allergic rhinitis.

Surgical and nonsurgical treatment options in patients with movement disorders of the platysma.

PURPOSE: Movement disorders of the platysma may constitute both an aesthetic and a functional problem for the affected patients, who almost always have hyperkinesis. This article describes the different treatment options for movement disorders of the platysma. PATIENTS AND METHODS: The therapeutic options that we used involved surgical and nonsurgical strategies (33 patients), including neurectomy of the cervical branch of the facial nerve, myectomy of the platysma, and the injection of botulinum toxin A. After therapy, patients were evaluated through self-assessment of the clinical outcome, clinical examination, and electromyography. RESULTS: All patients showed improvement or complete alleviation of their symptoms. The data also showed that resection of the cervical branch of the facial nerve after its anterograde neurolysis may be performed during facial nerve reconstruction. CONCLUSIONS: The various nonsurgical and surgical strategies are suitable for the treatment of different forms of platysmal movement disorders.
