Background:
Fingertip injuries are extremely common. Out of the various available reconstructive options, one needs to select an option which achieves a painless fingertip with durable and sensate skin cover. The present analysis was conducted to evaluate the management and outcome of fingertip injuries.Materials and Methods:
This is a retrospective study of 150 cases of fingertip Injuries of patients aged six to 65 years managed over a period of two years. Various reconstructive options were considered for the fingertip lesions greater than or equal to 1 cm2. The total duration of treatment varied from two to six weeks with follow-up from two months to one year.Results:
The results showed preservation of finger length and contour, retention of sensation and healing without significant complication.Conclusion:
The treatment needs to be individualized and all possible techniques of reconstruction must be known to achieve optimal recovery. 相似文献93.

Intercranial epidermoid tumours are benign lesions of congenital origin that are potentially curable. Although computerized axial tomography (CT) and magnetic resonance imaging (MRI) are usually diagnostic, a few atypical features sometimes make pre-operative diagnosis difficult. Two cases of cystic epidermoids with peripheral ring enhancement are reported. Relevant literature has been reviewed. 相似文献

BACKGROUND:Surgical management of giant medial sphenoid meningiomas (〉 or =5 cm in maximum dimension) is extremely challenging due to their intimate relationship with vital neural structures like the optic nerve, cranial nerves of the cavernous sinus and the cavernous internal carotid artery. Their surgieal management is presented incorporating a radiological scoring system that predicts the grade of tumour excision. MATERIALS AND METHODS: 20 patients of giant medial sphenoidal wing meningioma (maximum turnout dimension range: 5.2 to 9.5 cm; mean maximum dimension = 6.12 +/- 1.06 cm) with mainly visual and extraoeular movement deficits, and raised intraeranial pressure, underwent surgery. 相似文献

Relapse of Wegener's granulomatosis in the first trimester of pregnancy: a case report 总被引:3,自引:0,他引:3
The association of Wegener's granulomatosis and pregnancy is rare and poses
unique therapeutic challenges, particularly when active disease presents in
early pregnancy. We describe a 22-yr-old woman who recovered successfully
from her initial episode of Wegener's granulomatosis with a standard course
of treatment with prednisolone and cyclophosphamide. Two and a half years
later, she presented with relapse during the first trimester of pregnancy
(primigravida). Since the clinical features suggested mild disease, she was
started on prednisolone at a dose of 1 mg/kg/day, to which she seemed to
respond very well for 3 months. Unfortunately, she had a spontaneous
abortion at 5 months of gestation while on 25 mg/day of prednisolone. At
this time, her disease flared further, with clinically manifest lung
disease which was not part of her initial presentation. She was treated
with another course of oral cyclophosphamide and prednisolone, and a
remission was achieved in 4 months. There are no agreed guidelines on the
treatment of Wegener's granulomatosis during pregnancy. In this report, the
therapeutic issues are discussed against the background of the available
literature.

Double-balloon enteroscopy and capsule endoscopy have comparable diagnostic yield in small-bowel disease: a meta-analysis 总被引:1,自引:0,他引:1
SF Pasha JA Leighton A Das ME Harrison GA Decker DE Fleischer VK Sharma 《Clinical gastroenterology and hepatology》2008,6(6):671-676
BACKGROUND & AIMS: The aim of this study was to compare the diagnostic yield of capsule endoscopy (CE) with double-balloon enteroscopy (DBE) in small-bowel (SB) disease using meta-analysis. METHODS: We performed a search of studies comparing CE with DBE in SB disease. Data on diagnostic yield of CE and DBE were extracted, pooled, and analyzed. The weighted incremental yield (IY(W)) (yield of CE--yield of DBE) of CE over DBE and 95% confidence intervals (95% CIs) for pooled data were calculated using a fixed-effect model (FEM) for analyses without, and a random-effect model (REM) for analyses with, significant heterogeneity. RESULTS: Eleven studies compared CE and DBE; the pooled overall yield for CE and DBE was 60% (n = 397) and 57% (n = 360), respectively (IY(W), 3%; 95% CI, -4% to 10%; P = .42; FEM). Ten studies reported vascular findings; the pooled yield for CE and DBE was 24% (n = 371) and 24% (n = 364), respectively (IY(W), 0%; 95% CI, -5% to 6%; P = .88; REM). Nine studies reported inflammatory findings; the pooled yield for CE and DBE was 18% (n = 343) and 16% (n = 336), respectively (IY(W), 0%; 95% CI, -5% to 6%; P = .89; FEM). Nine studies reported polyps/tumors; the pooled yield for CE and DBE was 11% (n = 343) and 11% (n = 336), respectively (IY(W), -1%; 95% CI, -5% to 4%; P = .76; FEM). CONCLUSIONS: CE and DBE have comparable diagnostic yield in SB disease, including obscure gastrointestinal bleeding. CE should be the initial diagnostic test because of its noninvasive quality, tolerance, ability to view the entire SB, and for determining the initial route of DBE. Because of its therapeutic capabilities, DBE may be indicated in patients with a positive finding on CE requiring a biopsy or therapeutic intervention, if suspicion for a SB lesion is high despite a negative CE, and in patients with active bleeding. 相似文献
