Case Report: Untreatable Headache in a Child With Ventriculoperitoneal Shunt Managed by Use of New Non-invasive Intracranial Pressure Waveform.

brain4care, a new Food and Drug Administration (FDA)-cleared non-invasive sensor that monitors intracranial pressure waveforms, was used in a 13-year-old girl who presented with untreatable headaches. The patient had a history of craniopharyngioma resection and a ventriculoperitoneal shunt placement 7 years prior to the use of the device. Secondary obstructive hydrocephalus was also a present factor in the case.

Ca2+ /H+ exchange via the plasma membrane Ca2+ ATPase in skeletal muscle.

The aims of this work were to determine: 1) whether Ca2+ exit via the plasmalemmal Ca2+ ATPase (PMCA) is coupled to H+ entry via a Ca2+/H+ exchange; 2) whether operation of PMCA has an absolute requirement on external H+ (Ho); and 3) the stoichiometry and voltage-dependence of the Ca2+/H+ exchange. Barnacle muscle cells were used because of the ease with which they can be internally-perfused (e.g.

Osteonecrosis in patients with Hodgkin disease following combination chemotherapy.

Three cases of osteonecrosis in patients receiving prednisone as part of multi-drug chemotherapy for lymphoma are presented. These patients are discussed in the context of previously reported series. The etiology of steroid-induced osteonecrosis and its radiologic manifestations are reviewed with regard to the need for biopsy to confirm the diagnosis.

Gastrointestinal manifestations of the muscular dystrophies.

Five patients with acute megacolon with varied types of progressive muscular dystrophy are presented. Dysfunction of smooth muscle among patients with muscular dystrophy is reviewed. The extra gastrointestinal roentgen features are summarized.
