Phrenic nerve lesions as a result of birth trauma have been reported as a cause of acute respiratory distress infrequently. We report recent diagnostic and therapeutic experiences in four newborns with birth-traumatic phrenic nerve injury: one bilaterally, and three unilaterally, all right-sided. In each case, mechanical ventilation was required for at(More)
PURPOSE We studied the functional organization of the interictal epileptic spike complex in patients with benign rolandic epilepsy of childhood (BREC). METHODS We recorded interictal epileptiform spikes and somatosensory evoked potentials after median nerve stimulation, providing a biologic marker for the location of the central sulcus in 12 patients with(More)
Topographic EEG investigation with instant voltage mapping showed maximal negativity of 'rolandic' spikes over central or midtemporal electrodes with spread to parietal or upper frontal areas, and a dipole distribution (centrotemporal negativity, frontal positivity). There was no correlation of spike amplitude or duration with spread to adjacent areas. No(More)
The aim of this study was to investigate the influence of metabolic control on quantitative electroencephalographic (EEG) abnormalities in young diabetic patients. We compared quantitative EEGs of 44 insulin-dependent diabetic patients with age-matched controls. Furthermore, differences in EEG variables of diabetic patients and controls were correlated with(More)
Here, we report on a comprehensive collection of mainly early life cephalopods that were sampled during a research cruise to the Sargasso Sea with the RV Maria S. Merian in April 2015. A total of 2466 cephalopods were caught which belonged to at least 27 species (17 families). The most abundant family was represented by the hooked squids (Onychoteuthidae)(More)
In a prospective study we tested the hypothesis whether an alteration in the immunoglobulin light chain kappa and lambda is an expression of an autoimmune mechanism. We investigated 152 children (84 boys, 68 girls, age 12 months to 16 years). Immunoglobulins were analyzed by kinetic nephelometry. The patients were grouped according to clinical and(More)
Topographic EEG investigation with instant voltage mapping showed maximal negativity of "Rolandic" spikes over central or midtemporal electrodes with spread to parietal or upper frontal areas with a dipol formation (centro-temporal negativity, frontal positivity). Spike amplitude or duration was not correlated with spread to adjacent areas. No other focal(More)
Prolactin blood levels (HPRL) increase within 20 minutes postictally after generalized epileptic, especially generalized tonic-clonic seizures and return to normal values within one hour. Elevated HPRL levels were also observed after complex partial seizures, but usually in less extent, exceeding normal ranges only slightly. Therefore baselin HPRL(More)
