Fractures of the phalanges and the metacarpus are among the most common injuries of the upper extremity, accounting for approximately 10% of all fractures. They are not uncommonly dismissed as trivial trauma, so that the primary treatment is often inadequate. One fourth of all stiff fingers are attributable to a fracture, and in 50% of the cases, the fractures are the result of work-related accidents. This article aims to give an overview of the different types of fracture and their current treatment options (nonsurgical/surgical); special attention is also given to the specific features of phalangeal fracture treatment. 相似文献

Eight-channel transmit/receive body MRI coil at 3T. 总被引:1,自引:0,他引:1
P. Vernickel P. Röschmann C. Findeklee K.‐M. Lüdeke Ch. Leussler J. Overweg U. Katscher I. Grässlin K. Schünemann 《Magnetic resonance in medicine》2007,58(2):381-389
Multichannel transmit magnetic resonance imaging (MR) systems have the potential to compensate for signal-intensity variations occurring at higher field strengths due to wave propagation effects in tissue. Methods such as RF shimming and local excitation in combination with parallel transmission can be applied to compensate for these effects. Moreover, parallel transmission can be applied to ease the excitation of arbitrarily shaped magnetization patterns. The implementation of these methods adds new requirements in terms of MRI hardware. This article describes the design of a decoupled eight-element transmit/receive body coil for 3T. The setup of the coil is explained, starting with standard single-channel resonators. Special focus is placed on the decoupling of the elements to obtain independent RF resonators. After a brief discussion of the underlying theory, the properties and limitations of the coil are outlined. Finally, the functionality and capabilities of the coil are demonstrated using RF measurements as well as MRI sequences. 相似文献

Background From the endocrine surgeon’s perspective, it is important to know how endocrinologists manage patients with primary hyperparathyroidism
(pHPT). The aim of this survey was to evaluate the preoperative diagnostic workup and referral pattern for parathyroidectomy
by Swiss endocrinologists.
Materials and methods The survey was conducted by mailing a questionnaire to all members of the Swiss Society for Endocrinology and Diabetes in
spring 2005.
Results The questionnaire was sent back by 68 of 124 endocrinologists (55%). The median annual case volume of patients with pHPT was
6 (range 1–50). The mean fraction of these patients referred for surgery was 59 ± 24%. This fraction was significantly higher
in the German-speaking part of Switzerland than in the French-speaking part (67 ± 21% vs 51 ± 27%). When considering surgery
for asymptomatic pHPT, 62% of the endocrinologists rely routinely on the recommendations of the NIH consensus conference and
86% on the subsequent guidelines of the workshop in 2002. Sixty-seven percent of the endocrinologists routinely perform localization
studies before possible referral for surgical exploration. Typically, they consisted of an ultrasonography of the neck (93%)
and a 99mTc-MIBI scintigraphy (80%). The impact of the availability of a minimally invasive surgical procedure on the number of patients
referred for surgery seems to be considerable. Sixty-one percent of the participants would expand the indication for surgery
if the operation could be done by a limited surgical approach.
Conclusions In a relevant fraction of patients with pHPT, endocrinologists still do not regard curative therapy as mandatory. Surprisingly,
there are significant cultural differences concerning referral patterns to surgery between the German-speaking and the French-speaking
parts of Switzerland. Minimally invasive procedures seem to lower the threshold for referral for surgical therapy.

Humoral hypercalcemia of malignancy is widely associated with tumor production of parathyroid hormone related protein (PTH-rP).
This peptide functions in endocrine, autocrine and paracrine mechanisms in a manner similar to PTH; increasing renal uptake
of calcium, decreasing retention of phosphorous, and stimulating adenylate cyclase and phospholipase C. Although PTH-rP production
has been well documented in neoplasms of the exocrine pancreas, we present here two cases of endocrine pancreatic neoplasms
elaborating PTH-rP. We then review the literature of previous cases and delve into the pathophysiology of this peptide. 相似文献

BACKGROUND: The axillobilateral breast approach (ABBA) is a procedure allowing thyroid resection without scarring at the neck. We operated on a series of 26 patients with this technique. METHOD: Via incisions at the edge of the mamilla and axilla, trocars are placed subcutaneously under the platyma. Dissection is performed bluntly and with an ultrasonographic scalpel under videoscopic control. The procedure itself corresponds to conventional surgery. The specimen is removed through the axillary trocar. RESULTS: Twenty-six female patients underwent thyroid resection using the ABBA technique. Subtotal resection was performed in 24. Mean operation times were 111 min (unilateral) and 187 min (bilateral). In none of these cases was conversion necessary. One transient recurrent laryngeal nerve palsy and one paresis of the arm plexus were found postoperatively. CONCLUSION: In selected patients the ABBA technique is feasible and safe with the mandatory radicalness. The primary aim of this method is the cosmetic result. 相似文献
