Retrorenal colon: implications for percutaneous diskectomy

It has been recommended that computed tomography (CT) with the patient prone be performed in every patient undergoing percutaneous diskectomy; this would enable detection of a retrorenal location of the colon, which could interfere with the percutaneous procedure. In this evaluation of 346 prone CT studies, only one patient (0.29%) was found to have retrorenal or retropsoas bowel that would have been perforated at diskectomy. Because of this extremely low prevalence, the performance of prone CT in every patient undergoing percutaneous lumbar diskectomy is not believed to be necessary.     

Ultrasound biomicroscopic features of spherophakia

Background: Spherophakia is an uncommon diagnosis. This is the first case report of spherophakia evaluated by ultrasound biomicroscopy.
Methods: Ultrasound biomicroscopy is a new diagnostic technique developed by one of the authors and provides images with microscopic resolution of the anterior segment. A patient with spherophakia was evaluated by ultrasound biomicroscopy (Zeiss-Humphrey, 50MHz) before and after YAG laser iridotomy.
Results: Ultrasound biomicroscopic assessment revealed a shallow anterior chamber, a very steep anterior lens curvature, iridolenticular contact, elongated zonules, and an increased distance between the lens equator and the ciliary processes. Angle closure glaucoma was due to a pupil block mechanism. The pupil block was relieved by YAG laser iridotomy.
Conclusions: Ultrasound biomicroscopy is a useful technique to confirm the diagnosis of spherophakia. The pupil block in spherophakia is relieved by YAG laser iridotomy.

Appropriate target interactions prevent abnormal cytoskeletal changes in neurons: a study with intra-sciatic grafts of the septum and the hippocampus.

Transplantation of embryonic CNS regions into the PNS provides an opportunity to study temporal and spatial changes in the cytoskeleton that are associated with aging and neurodegenerative diseases. In this study, the fetal septum was transplanted alone or with the hippocampus into the sciatic nerves of young adult rats to determine whether the proper central neural target could prevent the expression of abnormal cytoskeletal changes. The substantia nigra, a non-target area of the septum, served as control co-grafts. After 1, 3, 6, 12, and 18 months of survival, the grafts were examined by immunocytochemistry with antibodies to phosphorylated and nonphosphorylated neurofilaments, microtubule-associated proteins (MAPs), and glial fibrillary acidic protein (GFAP). Subpopulations of neurons in the septal transplants expressed CAT and the NGF receptor (192-IgG). Long-term (12-18 months) expression of these two markers was only observed when the septum was combined with the hippocampus. Although isolated single grafts of septum survived within the PNS substratum, significant neuronal loss, extensive graft shrinkage, and aberrant cytoskeletal immunoreactivity were prominent in the long-term group. Changes that reflected an aging process included the ectopic expression of phosphorylated neurofilaments in neuronal perikarya, swollen axons, and a loss of MAP2 immunoreactivity that paralleled dendrite regression. In addition, abnormal "curly" fibers in the neuropil were also immunolabeled with an antibody directed against tau (5E2). Introduction of hippocampal co-grafts increased the final size of the septal transplants and prevented the cytoskeletal changes that accompanied the degeneration in the single septal grafts. The degree of GFAP immunostaining in the septum corresponded with advancing graft age and was minimized when grafted with the hippocampal formation. When the septum was combined with the substantia nigra, the grafts also underwent shrinkage and no protective influence from aberrant cytoskeletal staining was observed. These experiments exemplify the importance of an appropriate CNS neural target on the maintenance of long-term cholinergic neuron survival and normal morphology at the cytoskeletal level and illustrate the usefulness of these CNS-PNS constructs to examine conditions that influence the cytoskeleton.     

Die idiopathische Lungenhämosiderose,klinische Beobachtungen und radiologische Untersuchungen mit Eisen59 bei einem 17 jähr. Patienten

Zusammenfassung Nach Darstellung des klinischen Bildes der idiopathischen Lungenhämosiderose wird über eine eigene Beobachtung bei einem 17jährigen Patienten mit 10jähriger Anamnese berichtet. Das Krankheitsbild wurde von einer Eisenmangelanämie sowie den pulmonalen Infiltrationen beherrscht. Der Tod erfolgte an akutem Rechtsversagen des Herzens. Untersuchungen mit Fe⁵⁹ zeigten einen erhöhten Eisenstoffwechsel mit bevorzugter Deponierung des Radioeisens in der Lunge. Pathogenetisch ist nach den histochemischen Untersuchungen vonProbst das Auftreten von sauren Mukopolysacchariden in dem elastischen System der kleien Lungengefäße sowie des Lungenparenchyms selbst von Bedeutung. Die Eiseninkrustation in die elastischen Fasern tritt sekundär auf. Eine primäre Eisenstoffwechselstörung besteht nicht.
