The recurrent neurotrophic buttock ulcer in the meningomyelocele paraplegic: a sensate flap solution.

A large percentage of meningomyelocele paraplegic patients have a distal zone of sensation-bearing skin on their thighs. This sensate skin can be used as a fasciocutaneous flap to resurface a recidivistic ulcer after excision. In this study, because the transposition distance was significant, the flap length-width ratio was greater than normal and, therefore, required a 3-week elevation delay. This also permitted appraisal of the sensate flap after the first stage. The wound-healing was excellent after both stages. This reconstructive procedure was completed in four patients, with an average follow-up period of 13 years. These patients remain chronic sitters in administrative jobs and have been pressure sore-free after flap repair.

Folliculitis of the buttocks and pinworms. A case report.

Folliculitis, both superficial and deep, has increased in frequency, particularly during the warm months of the year. The frictional trauma from tight-fitting jeans, with overhydration and maceration of the skin, has contributed to the increase. Folliculitis is usually accompanied by pruritus, but when pruritus precedes the folliculitis, there may be another cause in addition to the wearing of tight clothes. Such was the case in our patient who had anal pinworms (Enterobius vermicularis).

Dialysis-related amyloidosis manifested as masses in the buttocks.

A 40-year-old man had enlarging painful gluteal masses that developed after 17 years of hemodialysis. Pathologic examination revealed extensive deposition of beta 2-microglobulin amyloid. A bladder biopsy done during evaluation for possible transplantation also showed amyloid deposits. This constellation of findings has not been reported in a patient with beta 2-microglobulin amyloidosis. Patients with dialysis-related amyloidosis should be carefully assessed for systemic involvement. Renal transplantation may prevent further amyloid deposition and provide relief of pain.

Effects of dietary marine oil supplementation on reactivity of human buttock subcutaneous arteries and forearm veins in vitro.

1. The vascular reactivity of resistance arteries isolated from gluteal skin biopsies and veins isolated from forearms of subjects fed marine oils were examined. 2. Twenty seven healthy adult males were randomly allocated to one of two different treatment groups. The first group received maxEPA (eicosapentaenoic acid 0.178 g g-1; docosahexaenoic acid 0.116 g g-1) capsules 10 g per day for 28 days while the second group received an equivalent amount of mixed oil placebo capsules. Biopsies were performed on day 29 (13 for gluteal sections; 14 for forearm vein biopsies). Subcutaneous arteries and veins were mounted in myographs and standard organ baths, respectively. 3. The internal diameter of the subcutaneous arteries at a calculated transmural pressure of 100 mmHg averaged 183.7 +/- 10.3 microns in the maxEPA group and 182.6 +/- 19.8 microns in the placebo controls. Arteries from subjects on maxEPA demonstrated increased sensitivity to angiotensin II (maxEPA vs placebo: -log EC50 (M) -8.36 +/- 0.18 vs -7.91 +/- 0.14) but not to noradrenaline or 5-hydroxytryptamine. Concentration-response curves to acetylcholine, substance P and sodium nitroprusside obtained for noradrenaline precontracted vessels were unaltered with marine oil treatment as was the concentration-response curve to calcium in K(+)-depolarized vessels. 4. Vein internal diameter at a calculated transmural pressure of 20 mmHg averaged 3.06 +/- 0.23 mm in the maxEPA group and 2.96 +/- 0.89 in the placebo group. Responses to noradrenaline, 5-hydroxytryptamine, angiotensin II and endothelin-1 were obtained in the absence and presence of indomethacin (1 microM) in veins from both maxEPA and placebo-treated subjects. Neither dietary supplementation with marine oils nor indomethacin had any effect on the responses obtained to these agonists.5. The major finding of the present study was that in general, maxEPA supplementation did not affect responses to various vasoactive substances on isolated subcutaneous arteries or forearm veins. An exception was the observation of an enhanced response to angiotensin II in subcutaneous resistance arteries studied in vitro. This effect was selective for angiotensin II and was not apparent in veins isolated from the forearm.
