ABSTRACT

Protocadherin 19 (PCDH19) mutations have been identified in epilepsy in females with mental retardation as well as patients with a "Dravet-like" phenotype. We aimed to elucidate the electroclinical phenotype associated with PCDH19 mutation, which is currently difficult to identify at onset leading to a delay in diagnosis. We retrospectively reviewed clinical and EEG data for 13 consecutive patients with PCDH19 mutations or deletions diagnosed at our centers from 2009 to 2011, and followed these patients into adolescence and adulthood. We identified a specific temporal sequence of electroclinical manifestations, identified as three main stages. During the first two years of life, previously healthy girls presented with clusters of afebrile focal seizures. Early seizures were recorded on video-EEG in 10/13 patients, and were focal (n=8) with temporo-occipital and frontal onset. Three patients with strictly stereotyped focal seizures underwent a pre-surgical work-up. Two patients started with generalized seizures, one presenting with early-onset atypical absences and the other generalized tonic-clonic seizures. During the course of the disease, from two to 10 years, seizures became fever-sensitive and continued to recur in clusters, although these were less frequent. Seizures were mainly described by eyewitnesses as generalized tonic-clonic, even though three of five seizures, recorded on EEG, showed a focal onset with fast bilateral spread. Atypical absences and fever-induced tonic-clonic seizures remained frequent in only one patient until the age of 16 years. No specific treatment or combination appeared to be more effective over another. Various degrees of cognitive or behavioural impairment were reported for all patients, but it was in the second decade that behavioural disturbances prevailed with hetero-aggressiveness and behaviour associated with frontal lobe abnormalities leading to psychosis in two. Early recognition of the above features should improve early diagnosis and long-term management of patients with epilepsy and PCDH19 mutations.

ABSTRACT

Apnoea is a rare but well-known clinical presentation of the Chiari type I malformation. It may be either obstructive or central in nature, and has been described in children, adolescents and adults. Here, we report a 4-month-old infant who presented with frequent central sleep apnoeas leading to the diagnosis of a Chiari type I malformation. Surgical repair resulted in complete resolution of the symptoms, normal respiratory parameters during sleep and normal psychomotor development. This case illustrates a very early presentation of the Chiari type I malformation with central apnoeas and suggests that this aetiology should be considered in the differential diagnosis of central apnoeas in infants, especially when they are associated with other neurological sign or symptom.

ABSTRACT

Benign childhood epilepsy with centrotemporal spikes (BECTS) is regarded as a benign form of epilepsy because of its usually favorable outcome, in terms of seizures. Eighteen children with BECTS were studied in terms of neuropsychological and learning abilities: intellectual quotient, oral language (phonological production, naming skills, verbal fluency and syntactic comprehension), drawing and visuo-spatial skills, visual and selective attention, verbal and visuo-spatial memory, reading, numeracy and spelling. The mean IQ of the population was within the normal range, but individual results were heterogeneous. Verbal functions and memory were normal. In contrast, drawing and visuo-spatial skills, attention and visuo-spatial memory were significantly weak compared to the normal range for age. Reading, numeracy and/or spelling ability were significantly delayed by one academic year or more in ten of the children. In conclusion, despite its benign outcome in terms of epilepsy, BECTS can be accompanied by specific cognitive disorders and low academic achievement.

ABSTRACT

A 2-day-old baby exhibited impressive paroxysmal attacks consisting of bradycardia, bronchospasm and vasomotor fits (Harlequin type) related to a rare, dominantly inherited form of dysautonomy called "familial rectal pain". These events were recurrently triggered by emotion, diaper changes or wiping of the perineal areas or eating. Sometimes they occurred spontaneously. Carbamazepine had an excellent effect on the fainting. At four years of age, the child had normal psychomotor development with only minimal symptoms, and very rare paroxysmal attacks. The father of the child has minimal symptoms of this entity, with essentially ocular manifestations. Familial rectal pain is a very rare entity that must always be considered as a possible aetiology of any life-threatening event in an infant because of the availability of a very effective treatment. The existence of minimal forms of familial rectal pain is possible, and it is likely that this entity is underdiagnosed. [Published with video sequences].
