Inherited Metabolic Diseases
Hoffmann G, Zchocke J, Nyhan WL, eds. Inherited Metabolic Diseases. Springer 2010, 448 pages, 58 illustrations, $139.00.
Inherited metabolic diseases are generally viewed with anxiety by house staff and general pediatricians. Clinical cases are usually rare and the clinical presentation of cases can be both non specific and complex, which leads to further apprehension among clinicians. This text gives concise information on diagnosis and management of inherited metabolic diseases and provides for a clinically based approach to inherited metabolic diseases.
Inherited Metabolic Diseases: A Clinical Approach is written in a very reader friendly manner. It has been co-authored by … Continue reading >>

Foerster et al1 were right to report their proton MR spectroscopy findings in children with hepatic encephalopathy but were wrong to claim to be the first. I draw your attention to their article, in which the authors make the statement, “Our study is the first…” This kind of statement adds nothing to the scientific or educational value of the report and is especially concerning because it… Continue reading >>

Flow-diverting stents such as the Pipeline embolization device (PED; ev3, Irvine, California) or Silk (Balt, Montmorency, France) were recently introduced in clinical practice for the treatment of fusiform and wide-neck intracranial aneurysms. These stents are designed to divert the flow in the parent artery, with reduction of inflow in the aneurysm leading to thrombosis. The deviceshave 30%–35% metal surface-area coverage … Continue reading >>
Softness of Endovascular Coils

The softness of endovascular coils enables the packing of an intracranial aneurysm at a higher density so complete embolization is possible. While softness is an important concept, it is rarely discussed in a quantitative fashion. This information is often regarded as proprietary by manufacturers and is not available to the public. Thus, we do not know what makes a coil soft and what makes … Continue reading >>
“Hippocampal Malrotation”: No Real Malrotation and Not Rare

We read with great interest the article relating to hippocampal malrotation (HIMAL) by Gamss et al.1 We did, however, find some of the terminology questionable. In particular, we thought that “incomplete hippocampal inversion” (IHI) would be a better descriptive term because the hippocampus is not “malrotated,” but rather probably the inversion was never completed. The authors themselves acknowledge this possibility when they write … Continue reading >>
