The evolution of HEN was marked by changes in the population treated and the modes of treatment after the emergence of gastrostomy and commercial diets. This justified the creation of a multidisciplinary, pediatric artificial nutrition unit.

In an open label study, we analyzed the efficacy of botulinum toxin injection at the lower limbs of patients with hereditary spastic paraparesis (HSP). Fifteen patients who showed disabling spasticity with no or poor effect of oral treatment were recruited consecutively. Botulinum toxin was injected (400 U; Botox Ò ) into the spastic muscles identified by clinical examination (equinus, varus, and pathological hip adduction). Patients were regularly assessed from the first day to the fifth month: spasticity (Ashworth), motor strength, range of movements, Functional Ambulation Categories (FAC), gait parameter, Rivermead Motor Assessment, self-analysis of benefit and satisfaction. We observed a moderate and significant (P < 0.05) reduction of ankle plantar flexor and hip adductor spasticity, with a partial increase in the range of the active and passive motion at the ankle and in gait velocity. At an individual level, six of 15 patients showed an increase in gait velocity. The FAC and RMA did not change. Patients often reported partial improvement in foot position and lower limb propulsion, and fair satisfaction. In conclusion, botulinum toxin injection can be effective in HSP patients with relatively ancient spasticity. This technique can be introduced into the therapeutic panel, which also includes physiotherapy, oral treatment and baclofen pump.

In patients with severe traumatic brain injury (TBI), a growth hormone deficiency (GHD) is frequent and may contribute to the cognitive sequelae and reduction in quality of life (QoL). Recent studies have suggested that GH replacement therapy (GHRT) can improve processing speed and memory. The aim of the study was to analyze the efficacy of GHRT on cognition, activities of daily living (ADL), and QoL and the factors that predicted and contributed to these effects. We included patients at least 1 year after their TBI and assessed pituitary functions (with stimulation tests), cognition (attention, memory, and executive function), participation in ADL and QoL. GHD was treated for at least 1 year in 23 patients, who were compared with 27 non-treated patients. Other deficiencies were also treated. Measurements were performed at baseline and 1 year later. An analysis of variance of the factors group and session (p ≤ 0.05) showed that most cognitive parameters had improved at 1 year (evidencing a session effect). A stronger effect of GHRT (i.e. a group x session interaction) was found for Rey Osterrieth complex figure recall and 2/6 domains in the QoL questionnaire ("personal" and "functional"). Trends (p ≤ 0.07) were also found for spatial orientation and immediate recall in the verbal memory test. Greatest improvements were associated with lower performance before treatment. The magnitude of the improvements in ADL and QoL was moderately correlated with the improvement in cognition. In conclusion, replacement therapy can improve cognition and QoL in patients with TBI who have GHD, especially in those with severe disabilities.

In stroke patients, it has been suggested that communication disorders could result from lexical and syntactic disorders in left hemisphere lesions and from pragmatics problems in right lesions. However, we have little information on patient behaviour in dyadic communication, especially in conversation. Here, we analyzed the various processes participating in communication difficulties at the rehabilitation phase (1-6 months) post-stroke, in order to define the main mechanisms of verbal and non-verbal communication (VC, NVC) disorders and their relationship with aphasic disorders. Sixty-three patients were recruited, who belonged to six groups, with left or right cortico-sub-cortical (L-CSC, R-CSC) or sub-cortical (L-SC, R-SC), frontal (Fro) or posterior fossa (PF) lesions. They were compared with an equivalent control group (gender, age, education level). We used the Lille Communication Test, which comprises three parts: participation to communication (greeting, attention, engagement), verbal communication (verbal comprehension, speech outflow, intelligibility, word production, syntax, verbal pragmatics and verbal feedback) and non-verbal communication (understanding gestures, affective expressivity, producing gestures, pragmatics and feedback). We also used the Functional Communication Profile and the Boston Diagnostic Aphasia Examination (BDAE). Decrease in participation was found in L-CSC, R-CSC and Fro patients. Verbal communication was essentially disrupted in L-SCS and L-SC groups, including by verbal pragmatic disorders, and to a lesser degree in frontal patients. Nonverbal communication was mainly affected in R-CSC patients, especially by pragmatic difficulties. L-CSC patients showed an increase in gesture production, compensating for aphasia. In conclusion, communication disorders were relatively complex and could not be summarised by syntactical and lexical difficulties in left stroke and pragmatic problems in right stroke. The former also showed severe verbal pragmatic difficulties. Frontal stroke also resulted in evident verbal and non-verbal disorders.
