Abstract: Background: The objective of this study was to determine the frequency, nature, and impact of sleep disorders in children and adolescents with Tourette syndrome and to raise awareness about their possible inclusion as a Tourette syndrome comorbidity. Methods: Using a prospective questionnaire, we interviewed 123 patients of age ≤21 years with a confirmed diagnosis of Tourette syndrome. Each completed questionnaire was then reviewed in accordance with Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria for categorization to a form of sleep disorder. Results: Of the 123 patients with Tourette syndrome, 75 (61%) had comorbid attention deficit hyperactivity disorder and 48 (39%) had Tourette without attention deficit hyperactivity disorder. The sleep problems observed included problems in the nature of sleep, abnormal behaviors during sleep, and impact of sleep disturbances on quality of life. Within these cohorts, 31 (65%) of the 48 Tourette-only patients and 48 (64%) of the 75 Tourette + attention deficit hyperactivity disorder patients could fit into some form of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, coded sleep disorders. Of the 48 Tourette + attention deficit hyperactivity disorder patients with sleep disorders, 36 (75%) had insomnia signs, which could be explained by the co-occurrence of attention deficit hyperactivity disorder and high stimulant use. However, 10 (32%) of the 31 Tourette-only patients with sleep disorders had insomnia irrespective of attention deficit hyperactivity disorder or medication use. Conclusions: Sleep problems are common in children with Tourette syndrome irrespective of comorbid attention deficit hyperactivity disorder, justifying their inclusion as a comorbidity of Tourette syndrome.

Primary myoclonus-dystonia is a childhood-onset autosomal-dominant movement disorder with myoclonic jerks and dystonia. The authors report 9 children (4 boys, 5 girls) with myoclonus-dystonia from 8 families seen over a 4-year period at Cleveland Clinic. The mean age of onset of symptoms was 2.8 years, but the diagnosis was made at a mean of 7.3 years. Myoclonus was the presenting symptom in 8 children. A known pathogenic mutation in the ε-sarcoglycan gene (SGCE) was identified in 4 of the 9 children, and 2 other children had novel mutations in the same gene. Good response to trihexyphenidyl and clonazepam was seen. Two patients underwent deep brain stimulation surgery of the bilateral globus pallidus pars interna. In 7 children, the diagnosis of myoclonus-dystonia was not considered by the referring child neurologists, which led to extensive investigations and a delay in the final diagnosis. In this report, the authors highlight the need for increased awareness of this entity among child neurologists. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 9-month-old boy diagnosed with neurologic complications in infective endocarditis (IE) caused by Staph aureus. On admission, he had fever, rash, recurrent episodes of vomiting and irritability. The study highlights the neurological complications of IE. The article mentions that prompt identification and initiation of appropriate antibiotics reduces the risk of ischemic stroke. It also recommends avoiding anticoagulant therapy in the setting of IE.

Benign external hydrocephalus (BEH) is considered a self-limiting condition in infants. Subdural hematoma (SDH) in infants without a history of trauma indicates nonaccidental injury (NAI). The authors studied whether SDH can complicate BEH without apparent trauma. Out of 45 children younger than 3 years with nontraumatic SDH, 9 (7 boys) with mean age 6 months had BEH as risk factor. Symptoms included increasing head size (8), fussiness, and irritability (3). Three had up-gaze restriction, 1 axial hypotonia, and 6 normal examination. Neuroimaging showed prominent extra-axial spaces; SDH was bilateral (6), subacute (5). Other etiological workup for SDH was negative except NAI in 1. Two required evacuation of SDH and subdural–peritoneal shunt; others managed conservatively. Development was normal in 8 on follow-up. On follow-up imaging of 8, SDH completely resolved in 3, markedly reduced in 3, and remained stable in 2. BEH is a risk factor for SDH in infants, thus not always benign. [ABSTRACT FROM PUBLISHER]

A two-and-a-half-year-old male child presented with recurrent attacks of intractable vomiting, psychomotor retardation since 14 months of age. He had also lower cranial nerve palsy and corticospinal involvement. Magnetic resonance imaging had shown multiple well circumscribed areas of hypointusity in T1 weighted image which were brightly hyperintense in heavily T2-weighted image. The lesions were seen in basal ganglia, thalamii and brainstem and spared mamillary bodies. Magnetic resonance spectroscopy demonstrated lactate peak in the affected areas confirming the diagnosis of Leigh's disease. The child responded well to large dose of vitamin 'B' therapy.
