Reading ability and processing in Duchenne muscular dystrophy and spinal muscular atrophy

We analysed the reading abilities and processing of 21 children with Duchenne muscular dystrophy (DMD), 11 matched children suffering from spinal muscular atrophy (SMA) and 42 children receiving normal education. The principal result observed was that the DMD children exhibited a reading age which was significantly lower than the SMA children compared with their chronological age. These learning disabilities were not related to a deficit in non-verbal performance intelligence, but psycholinguistic evaluation showed a deficit in verbal intelligence, especially in the Similarities and Arithmetic WISC-R subtests, in phonological abilities, oral word repetition, and in digit span score. The results for the DMD children were heterogeneous, and ranged from normal to greater or lesser involvement. In an attempt to clarify the nature of this reading impairment in DMD children, the three groups (DMD, SMA, and normal control children) were tested by reading aloud a list of single words and non-words. The DMD children were significantly impaired in reading non-words, suggesting reading disability similar to dysphonetic dyslexia, the most frequent subtype of developmental dyslexia. These results are discussed in the light of psychometric data available for our DMD population and in the light of previous studies. The practical consequences of diagnosis on rehabilitation are very important. The precise description of the cognitive deficits seen in DMD is of value for future clinical and genetic studies.

Transition from pediatric to adult care system in patients with complex epilepsies: Necker model for transition evaluated on 70 consecutive patients

OBJECTIVE

Complex epilepsies such as epileptic and developmental encephalopathies require multidisciplinary care throughout life. A coordinated transition program is therefore essential to provide optimal support for patients leaving pediatric for adult care. The aim of this study is to describe and evaluate our transition program for complex epilepsies, focusing on the last step in this program, that is, the multidisciplinary transition day hospital (MTDH).

METHODS

We performed a retrospective observational study including patients with complex epilepsies who underwent the full steps of the transition program at Necker-Enfants Malades Hospital between May 2021 and June 2023, with a follow-up until February 2024. We described the cohort and detailed the interventions performed during the MTDH including medical, medicosocial, educational, daily life abilities, and laboratory and imaging assessments with the participation of one member of the adult team. We evaluated two indicators of our program: (1) the "adult first clinic attendance rate," defined by the percentage of patients attending their first adult clinic; and (2) the "return rate," defined by the percentage of patients who requested a pediatric encounter after their transfer.

RESULTS

Our cohort included 70 patients with a mean age of 19.1 years (interquartile range = 16.3-19.5). Eighty percent had an epilepsy syndrome diagnosis; 72.8% were treated with three or more antiseizure medications. All patients had their appointment at the adult clinic within 6 months of the day hospital, and only two families requested a pediatric encounter after the transfer.

SIGNIFICANCE

The transition program is key for an optimal transfer of patients with complex epilepsies to adult care. It requires a comprehensive multidisciplinary approach and provides a complete summary of the medical record. Our program secures a smooth landing in adult care and is a promising model to better manage the challenging transition process, especially in patients with complex epilepsy.

Spontaneous retraction pockets in chronic otitis media medical and surgical therapy

Results of a series of 228 spontaneous retraction pockets in chronic otitis media are reported and a classification is proposed. Under medical therapy, 78 retraction pockets of stage I and II (out of 95) were followed for five years. Sixteen percent deteriorated into stage III and were operated on; the others stabilized or improved towards normal tympanic membrane (23%). Different methods of surgical therapy were used in 150 retraction pockets (all the stages III and many stages II). Even with silastic sheeting and strengthening of the tympanic membrane, a recurrent retraction pocket was observed in 24 cases (16%). Functional results were obviously better when the ossicular chain was rebuilt from an intact malleus to an intact stapes and either from an intact malleus to a mobile footplate or from the tympanic membrane to an intact stapes. Surgery of retraction pockets must be used not only to prevent cholesteatoma formation but also to prevent erosion of the stapes.
