Regional versus general anesthesia for donor nephrectomy: effects on graft function.

Various general and regional anesthesia methods are used successfully in living-donor kidney transplantation. This study compared kidney graft function after general versus combined spinal-epidural anesthesia for donor nephrectomy. The study groups included recipients who received grafts from donors who had undergone nephrectomy under general anesthesia (GA group; n=10), and recipients who received grafts from donors who had combined spinal-epidural anesthesia (CSE group, n=10). Standard continuous epidural anesthesia was administered during all transplantations. Graft function was assessed using scintigraphy and Doppler ultrasonography on days 3 and 7. Urine levels of microalbumin, creatinine, and creatinine clearance rate were measured/calculated in 24-hour urine samples collected on postoperative days 3 and 7. There were no differences on either day 3 or day 7 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P >.05 for all). There were also no differences between the groups with respect to other scintigraphic findings on day 3 or day 7 (P >.05 for all). Ultrasonography on day 7 showed significantly higher mean peak systolic flow in the main renal artery in the CSE group than in the GA group (P=.035). The results suggest that GA and CSE for donor nephrectomy have similar effects on kidney graft function in recipients.

Reduced joint pain after short-term duodenal administration of seal oil in patients with inflammatory bowel disease: comparison with soy oil.

BACKGROUND: Rheumatic joint pain is a common extra-intestinal complication of inflammatory bowel disease (IBD). Because the high ratio of n-6 to n-3 fatty acids (FAs) of the Western diet might promote rheumatic disorders, we sought to compare the effects of short-term duodenal administration of n-3-rich seal oil and n-6-rich soy oil on IBD-related joint pain. METHODS: Nineteen patients with IBD-related joint pain were included in the study; 9 had Crohn disease and 10 had ulcerative colitis. Ten millilitres seal oil (n = 10) or soy oil (n = 9) was self-administered through a nasoduodenal feeding tube 3 times daily for 10 days. RESULTS: Compared with soy oil treatment, seal oil significantly reduced the duration of morning stiffness (P = 0.024), number of tender joints (P = 0.035), intensity of pain (P = 0.025) and the doctor's scoring of rheumatic disease activity (P = 0.025) at the end of the 10-day treatment period. Analysis of the effects as area under the curve (area between the curve and baseline, zero) for the entire period from start of treatment until 6 months' post-treatment suggested a long-lasting beneficial effect of seal oil administration on joint pain, whereas soy oil tended (not significantly) to aggravate the condition. Consistently, the serum ratios of n-6 to n-3 FAs (P < 0.01) and arachidonic acid to eicosapentaenoic acid (P < 0.01) were reduced after treatment with seal oil. CONCLUSION: The results suggest distinctive, differential prolonged effects on IBD-related joint pain of short-term duodenal administration of n-3-rich seal oil (significant improvement) and n-6-rich soy oil (tendency to exacerbation).

The canal of the posterior ampullar nerve: an important anatomic landmark in the posterior fossa transmeatal approach.

The canal of the posterior ampullar nerve is located between the inferior part of the internal acoustic meatus and ampulla of the posterior semicircular canal. It permits a more accurate localisation of the underlying labyrinth in inner-ear surgery. An anatomical and radiological study was undertaken to determine the importance the relationship between the canal and the labyrinth. Ten dry and 10 cadaveric temporal bone dissections, together with 20 high resolution CT scans of the same temporal bones were studied in an attempt to describe the anatomy of the canal of the posterior ampullar nerve. The length of the canal of the posterior ampullar nerve, the length of internal acoustic meatus, and distances from porus acusticus to the singular foramen and the transverse crest, and from the singular foramen to the vestibule and transverse crest, and from operculum to the sigmoid sinus and to the porus acusticus were measured. During the transmeatal posterior cranial fossa approach using the canal of the posterior ampullar nerve as a landmark enables more bone to be safely removed from the internal acoustic meatus thus preserving hearing.
