The case reported is of a 46 year old male who presented with a history of acute on chronic knee pain. The clinical features and investigations suggested a tear of the quadriceps tendon, with pre‐existing chronic calcific enthesopathy. The operative findings were of an acute collection of calcific material within the quadriceps tendon. This acute presentation and calcific collection have not previously been reported in the quadriceps tendon. 相似文献

PURPOSE: To evaluate semiautomated analysis software for measuring the total carotid arterial wall volume (TWV) as a measure of atheroma burden. MATERIALS AND METHODS: Semiautomated-software and manual analyses of TWV measured by cardiovascular magnetic resonance (CMR) were compared in two phantom models, 10 subjects with no known carotid artery disease, and eight subjects with known carotid disease. The subjects were scanned twice for reproducibility. RESULTS: In subjects with no known carotid disease, semiautomated analysis of 98% of slices showed an improved interstudy coefficient of variation (COV) compared to manual analysis of 50% of slices (4.0% vs. 6.2%, P = 0.02). The proportion of matched cross-sectional slices usable for TWV measurement was superior (99% vs. 49%, P = 0.005) and the median analysis time was shorter (31 minutes vs. 90 minutes, P < 0.001) using the semiautomated software. In subjects with known carotid disease, semiautomated (99% of slices) and manual (56% of slices) analyses had comparable interstudy COVs (4.1% vs. 3.9%, P = 0.01). However, the proportion of matched cross-sectional slices usable for TWV measurement was greater using semiautomated contouring (96% vs. 56%, P = 0.01). CONCLUSION: Carotid CMR measurement of TWV using novel semiautomated analysis software shows good reproducibility, enables greater coverage of arterial vessel wall length, and is considerably faster compared to manual contouring. 相似文献

Sebaceous glands are common in the oral mucosa, but are not normally present with in the jaws. A case of an odontogenic keratocyst with sebaceous glands in the epithelium in a 12-year-old child is presented here, with special emphasis on its histogenesis. 相似文献

Salvage of limbs with vascular trauma. 总被引:9,自引:0,他引:9
In an eight-year period we treated 51 cases of vascular injury associated with fractures and/or dislocations or soft-tissue injuries of the limbs. We relied on a clinical diagnosis and immediate exploration of blood vessels rather than the time-consuming procedure of arteriography. All patients were operated on by the orthopaedic residents on duty and not by vascular surgeons. Only 17 (33%) were repaired within six hours of injury. Limb viability with good function was obtained in 38. Complications included six deaths, four amputations, two renal failures and delayed occlusion in one case. 相似文献

Folic acid intake reduces the risk of neural tube defects (NTDs). Although
the 677C-->T mutation in the 5,10-methylenetetrahydrofolate reductase
(MTHFR) gene is a risk factor for NTDs, it only partly explains the
elevated homocysteine levels in mothers of children with NTDs. We measured
vitamin B12, folate and homocysteine in patients with spina bifida (SB),
their parents, and in controls, to investigate which other enzymes of
homocysteine metabolism might be defective. Because homozygosity for the
677C-->T mutation causes decreased plasma folate and increased red-cell
folate (RCF) and plasma homocysteine levels, we excluded individuals
homozygous for that mutation. The remaining SB patients and their parents
still had lowered plasma folate and elevated total homocysteine levels, and
a small subset had decreased vitamin B12 levels. Red-cell folate was the
same in all groups, suggesting that dietary folate intake and its uptake
was normal. Risk of SB was increased at the 25th percentile of plasma
folate and at the 75th percentile of homocysteine values in SB patients and
their parents, and at the 5th and 25th percentiles of vitamin B12 in
mothers with SB- affected offspring. This underlines the functional
importance of homocysteine remethylation to methionine. There was no
correlation between vitamin B12 and homocysteine or RCF. In combination
with the lowered plasma folate (80-90% 5-methyltetrahydrofolate), our data
do not support a major involvement of methionine synthase in the aetiology
of SB. Our data rather favour the involvement of genetic variation at loci
coding for the formation of 5-methyltetrahydrofolate, such as MTHFR,
methylenetetrahydrofolate dehydrogenase or serine hydroxymethyltransferase.

An extremely rare case of fibromatosis in a 25-year-old Indian male is reported. The clinical examination and pre-operative findings were suggestive of a benign neoplasm, probably of neurogenic origin. The mass was well circumscribed and could be shelled out en masse. Histopathological examination showed it to be fibromatosis. An external rhinoplasty approach enabled a complete wide excision to be performed without any resulting cosmetic defect. 相似文献
