The differential leukocyte count in shigellosis.

We analysed the peripheral leukocyte count of 80 children with shigella gastroenteritis. The total leukocyte count varied widely from leukopenia to leukocytosis, and is therefore of little value in differentiating shigellosis from viral gastroenteritis. The leukocyte differential count, however, revealed a striking shift to the left in 71% of the patients. This parameter may help in the preliminary diagnosis of shigella gastroenteritis. We have stressed the fact that three pediatric textbooks do not refer to this aspect in their relevant chapters on shigellosis.

A TIA-like syndrome associated with Mycoplasma pneumoniae infection.

A transient expressive aphasia associated with focal slowing in the electroencephalogram, is described in a patient with documented Mycoplasma infection. The hypothesis that ischemia is a mechanism for the transient clinical findings is considered in relation to animal studies.

Use of demand pacemaker in children with Guillain-Barré syndrome and cardiac arrhythmias.

We report 2 patients with Guillain-Barré syndrome who exhibited autonomic dysfunction, including lability of blood pressure and heart rate, frequent episodes of profound bradycardia, and occasional asystole. Both patients required insertion of a temporary venous pacemaker which was activated a few times during the following days. The potential need for ventilatory support in patients with Guillain-Barré syndrome is well known; however, death in these patients due to acute cardiovascular failure during autonomic dysfunction continues to occur. The patients' courses emphasize the significance of cardiac monitoring and the potential use of cardiac pacing in Guillain-Barré syndrome patients who exhibit autonomic dysfunction.

MRI in neonatal dural sinus thrombosis.

Dural sinus thrombosis in the newborn period is a rare but underrecognized condition which may cause seizures, macrocephaly, lethargy, and respiratory depression. A 10-day-old term infant with no pre- or perinatal risk factors for thrombosis presented with seizures and was found to have dural sinus thrombosis on computed tomography and magnetic resonance imaging (MRI). One week later, MRI revealed partial resolution and 3 weeks later disclosed a complete resolution of the thrombosis. Clinicians should consider the diagnosis of neonatal dural sinus thrombosis in infants presenting with seizures and/or increased intracranial pressure even in the absence of risk factors or when the cranial computed tomography is normal. MRI is the most sensitive diagnostic tool to establish the diagnosis and permit a noninvasive follow-up, contributing to our understanding of the natural history, associated pathology, and prognosis of this condition.

Basilar artery migraine and reversible imaging abnormalities.

We report a case of a basilar artery migraine in a 17-year-old boy with transient CT and MR abnormalities after each of two migraine episodes. A repeat MR study 6 months after the last event showed complete resolution of the lesion. Transient abnormalities on brain images similar to those shown in our case have been reported in patients with migraine and other neurologic conditions and are most likely related to cerebral vasogenic edema.
