The relationship between body size and depression symptoms in adolescents.

OBJECTIVE: To evaluate the relationship between body size and depressive symptoms, as well as the moderating effects of age, sex, and socioeconomic status (SES), in a sample of young adolescents. STUDY DESIGN: The study group comprised 678 young adolescents (age 11 to 14 years). Body mass index (BMI) z scores were used to estimate body size. Depression symptoms were assessed using the Children's Depression Inventory (CDI). The spline function was used to examine the shape of the relationship between BMI z score and depressive symptoms. RESULTS: In the total sample, CDI scores were lowest for BMI z scores between -1 and -0.5. CDI scores increased progressively for BMI z scores > 0. In boys, CDI scores increased for BMI z scores > 2, whereas in girls, CDI scores increased for BMI z scores > -0.5 and < -1. Age did not have a significant moderating effect. SES had a moderating effect only in boys (P = .011). CONCLUSIONS: The relationship between body size and depressive symptoms in young adolescents is curvilinear and is moderated by sex. Heavier-than-average and underweight girls, as well as obese boys, had the highest depression scores.

Epileptic spasms in clusters without hypsarrhythmia in infancy.

Spasms are defined as epileptic seizures characterized by brief axial contraction, in flexion, extension or mixed, symmetric or asymmetric, lasting from a fraction of a second to 1-2s, and are associated with a slow-wave transient or sharp and slow-wave complex, followed or not by voltage attenuation. Epileptic spasms usually appear in clusters and are age-dependent. This type of epileptic spasms associated with the particular EEG pattern, hypsar rhythmia, constitutes the basis for the diagnosis of West syndrome. The question is, how to nosologically define those patients who clearly present epileptic spasms in clusters without modified or typical hypsarrhythmia and with or without focal paroxysmal discharges on the interictal EEG. In the present series, the four patients show that epileptic spasms in clusters may occur in infancy, without hypsarrhythmia. They all presented the following features: normal neuropsychological development before onset of epileptic spasms, clusters of epileptic spasms, focal clinical and/or EEG abnormalities, normal neuroradiological imaging, neurometabolic investigations and karyotypes. In three of the patients, seizures were refractory to AEDs. Epileptic spasms in clusters without hypsarrhythmia that start in the first year of life represent a subtype of infantile spasms that generally are refractory to AEDs. It is not yet clear whether it should be considered as a variant of West syndrome or not [Published with Video sequence].
