Hypocapnia prevents the decrease in regional cerebral metabolism during isoflurane-induced hypotension.
In neurologic surgery, induced hypotension is often used while the patient is hypocapnic. We investigated, by tissue biopsy methods and scintillation counting, the regional cerebral glucose utilization (rCMRglc) and blood flow (rCBF) in rats subjected to hypocapnia alone and in combination with hypotension. Anesthesia was maintained with 1.0% isoflurane in nitrous oxide/oxygen. ⋯ During hypocapnia/hypotension, rCBF was unaltered in cortical areas, while increases were seen in all subcortical areas compared to hypocapnia. Regional values of the ratio of rCBF/rCMRglc indicated that during hypocapnia and hypotension induced by isoflurane in nitrous oxide/oxygen, the individual brain areas were perfused according to their metabolic needs. It is suggested that hypocapnia may prevent the decrease in rCMRglc, which is usually observed during deep isoflurane anesthesia.

Case Reports[Autologous injection of fatty tissue following liposuction--not a method for breast augmentation].
In recent years autologous fat transplantation employing liposuction has become an established method for correction of small soft tissue defects and irregularities of skin contour. Only a small amount of fat may be used because fat cells will be nourished by perifusion alone until neovascularisation occurs. Transplantation of a large amount of fat will result in fat necrosis. The inappropriate use of fat for breast augmentation after liposuction is described in a case report.

Investigation of the flexible ruler as a noninvasive measure of lumbar lordosis in black and white adult female sample populations.
The opinions or assertions contained herein are the private views of the authors and are not to be construed as official or reflecting the views of the Army, the Department of Defense, or the U. S. Government. ⋯ The criterion validity of the flexible ruler as a measure of actual lumbosacral lordosis was poor (Pearsons' Correlation Coefficient = 0.30, N = 45). Because of the poor criterion validity of the flexible ruler compared to roentgenographically confirmed lumbar lordosis, the flexible ruler has questionable clinical value in the assessment of lumbar lordosis.

[Corrective possibilities of burn contractures of the large joints].
Major joint movement is frequently limited following full-thickness burns of the extremities due to scar contractures. After operative correction of the contractures physical therapy is absolutely necessary. Skin contractures are treated with Z-plasty, skin graft, local flaps, pedicled flaps and free tissue transfer. The advantages and disadvantages of those procedures are described.
