RESUMEN
INTRODUCTION: This study aimed to investigate selective muscle involvement by shear wave elastography (SWE) in patients with spinal muscular atrophy (SMA) types 2 and 3 and to compare SWE values with magnetic resonance imaging (MRI) in demonstrating muscle involvement. METHODS: Seventeen patients with SMA types 2 and3 were included in the study. SWE was used to evaluate stiffness of the upper and lower extremities and paraspinal muscles. Involvement of the paraspinal muscles was evaluated using 1.5-T MRI. RESULTS: Among the upper extremity muscles, SWE values were the highest for the triceps brachii; however, no significant difference was noted (p = 0.23). In post hoc analysis, a significant difference was observed between triceps brachii and biceps brachii (p = 0.003). Patients with a longer disease duration have the highest SWE values for the triceps brachii (r = 0.67, p = 0.003). Among the lower extremity muscles, SWE values for the iliopsoas were significantly higher than the gluteus maximus (p < 0.001). A positive correlation was found between SWE values and MRI scores of paraspinal muscles (r = 0.49, p = 0.045; r = 0.67, p = 0.003). CONCLUSION: This is the first study to report muscle involvement assessed by SWE in patients with SMA types 2 and 3. Our findings are similar to the presence of selective muscle involvement demonstrated in previous studies, and also SWE and MRI values were similar. SWE is an alternative noninvasive practical method that can be used to demonstrate muscle involvement in patients with SMA, to understand the pathogenesis of segmental involvement, and to guide future treatments or to monitor the effectiveness of existing new treatment options.

BACKGROUND: Psychosocial and behavioral disorders have been reported in childhood epilepsy with centrotemporal spikes (CECTS). We aimed to identify the symptoms of eating disorders in CECTS. METHODS: Patients with CECTS were recruited from the pediatric neurology outpatient clinic between September 2019 and July 2020. The Children's Eating Behaviour Questionnaire (CEBQ) was administered to 39 patients and 31 controls. Patients' scores were compared with those of healthy subjects. RESULTS: There was no significant difference between the CEBQ of patients with CECTS and the control group (pâ¯>â¯0.05). There was no significant difference between the BMI of the patients with CECTS and the control group. In the patient group with CECTS, no significant difference was found in terms of CEBQ according to the antiepileptic drug used and EEG findings (pâ¯>â¯0.05). CONCLUSION: No difference was found in the eating habits of patients with CECTS compared with the healthy control group.

BACKGROUND: The objective of this study is to investigate the efficacy of continuous renal replacement therapy (CRRT), mainly continuous venovenous hemodiafiltration (CVVHDF), and evaluate vasoactive requirements in hyperammonemic neonates and infants. METHODS: Patients who underwent CRRT for hyperammonemia were retrospectively analyzed. MEASUREMENTS AND MAIN RESULTS: Patients in 7 of the encounters were treated solely by CVVHDF. During 3 encounters, patients who received continuous venovenous hemodialysis (CVVHD) were transitioned to CVVHDF. CVVHD was used in 3 encounters. The median 50% reduction time for ammonia was 8 h (range 3-15 h). The median duration of CRRT treatment was 40 h (range 24-89 h). Survival to hospital discharge occurred in 12 encounters (92.3%). Eleven encounters (84.6%) were treated with different vasoactive agents. In those encounters, the median vasoactive medications' start time was the 6th hours (range 2-60 h) of CRRT. There was no association between the vasoactive index score and pre-dialysis ammonia concentration. CONCLUSIONS: CRRT achieves timely control of hypeammonemic states. Hemodynamic instability necessitating intervention with vasoactive medications is a common finding in patients with hyperammonemia.

In recent years, with advances in molecular genetics, many new mutations with various ataxic syndromes have been identified. Recently, homozygous sequestosome 1 (SQSTM1) gene variant with a progressive childhood-onset cerebellar ataxia, dystonia and gaze palsy was described. Here we describe a patient with progressive cerebellar ataxia and gaze palsy, as well as myoclonus, cognitive impairment and growth retardation with a homozygous SQSTM1 variant NM_003900.5:c.55G > T (p.Glu19*). Our case had brainstem lesions on brain magnetic resonance imaging that have not been previously reported. This novel finding expands the SQSTM1 gene-associated neuroradiologic spectrum. Homozygous SQSTM1 variant should be considered in the differential diagnosis in patients presenting with cerebellar findings, gaze palsy, and cognitive impairment to facilitate early diagnosis and genetic counseling.
