AIM: Peritonectomy procedures with intraperitoneal chemohyperthermia are an effective but costly treatment for peritoneal carcinomatosis (PC). Consequently a proper selection of patients is necessary. We evaluated the benefit of MRI prior to surgery, in the detection of two of the main surgery contraindications: bulky mesenteric tumors and bladder implants. METHODS: Three experts retrospectively reviewed abdominal and pelvic MRI from 19 cases of surgically proved PC (ovary: 7; colorectal: 7; gastric: 2; pseudomyxoma peritonei: 2; appendix: 1). RESULTS: Mesenteric tumors were always identified as hypersignal masses on axial and coronal fat suppression gadolinium-enhanced T1 images (n=3). Three out of five bladder implants were detected. The two cases of bladder implants that were not detected on MRI were missed because the bladder was not filled. The best sequence for the detection of bladder involvement was axial T2-weighted images with bladder filling. CONCLUSIONS: Evaluating the preoperative resectability of PC is crucial for patient management. MRI seems to reliably detect bulky mesenteric tumors and bladder implants on condition the bladder is filled and appropriate sequences are used. 相似文献

A common distal radio-ulnar joint (DRUJ) stabilisation procedure uses a tendon graft running from the lip of the radial sigmoid
notch to the ulnar fovea and through a bony tunnel to the ulnar shaft, before being wrapped round the distal ulna and sutured
to itself. Such graft fixation can be challenging and requires a considerable tendon length. The graft length could be reduced
by fixing the graft to the ulna using a bone anchor or interference screw. The aim of this study was to compare the strength
of three distal ulna graft fixation methods (tendon wrapping and suturing, bone anchor and interference screw). Four human
cadaveric ulnae were used. A tendon strip was run through a tunnel in the distal ulna and secured by: (1) wrapping round the
shaft and suturing it to itself, (2) a bone anchor and (3) an interference screw in the bone tunnel. Load to failure was determined
using a custom-made apparatus and an Instron machine. Maximum failure load was highest for the bone anchor fixation (99.3 ± 23.7 N)
followed by the suturing (96.2 ± 12.1 N), and the interference screw fixation (46.9 ± 5.6 N). There was no significant difference
between the tendon suturing and bone anchor methods, but the tendon suturing was statistically significantly higher compared
to the interference screw (P = 0.028). In performing anatomical stabilisation of the DRUJ fixation of the tendon graft to the distal ulna with a bone
anchor provides the most secure fixation. This may make the stabilisation technique less demanding and require a smaller tendon
graft. 相似文献

Chandipura virus (CHPV) has emerged as an important pediatric encephalitis-causing pathogen with very high mortality in India. No specific vaccine or treatment is available till date. We attempted to prepare a candidate vaccine employing recombinant CHPV Glycoprotein (rGp). The Glycoprotein gene (G-gene) of CHPV was expressed using Baculovirus expression system. The rGp was purified by HPLC and used for mice immunization, 3 doses, and 4 weeks apart. One microgram rGp was found to be optimum. Sero-conversion was observed as early as 2nd week by detecting anti-CHPV IgG antibodies. Antibody titres were immunogen-concentration dependent. Intracerebral challenge of the immunized mice with 100 LD50 of the homologous strain demonstrated 90% protection. In in vitro neutralization, antibodies from the immunized mice were able to neutralize heterologous viruses. There was 60% T cell proliferation observed against rGp in immunized mice. The study shows that rGp induces both arms of immune response and represents an ideal vaccine candidate for further evaluations. 相似文献

Medial epicondylitis is a chronic noninflammatory condition resulting from mechanical injury. Despite many treatment options,
including rest, medications, physiotherapy and operative interventions, the results are too often poor; thus new treatment
options are sought. We treated 4 men with chronic epicondylitis (5 affected joints) with extracorporeal shock wave therapy
after failed attempts of other treatments. The patients’ complaints were graded with the Nirschl scoring system prior to and
six months after therapy. The treatment consisted of three sessions, at 20-day intervals, of 3000 pulses of ultrasonic shock
waves from a Piezolith 3000 unit (energy dosage was gradually increased to reach step 10 equaling 0.9 mJ/mm2). At the 6-month follow-up, no patient was pain free. Three cases had slightly lower Nirschl scores than prior to the procedure
but the patients rated this difference as insignificant; two cases were unchanged. No complications were observed but all
patients rated the procedure as very unpleasant. The well recognized biologic effects of ultrasonographic waves (heat generation,
oscillations, cavitation, etc.) that result in functional and structural changes of cellular membranes with sonochemical reactions
(acceleration of normal metabolism, oxygenation and reduction in water solutions, polymer degradation, etc.), even if present
in our cases, did not result in a noticeable decrease of symptoms, even though we used high energy and more impulses per session.
Significant variations in methodology make inconclusive the results of numerous reports on the use of extracorporeal shock
waves in epicondylar degenerative problems, although ineffectiveness of such therapy is the conclusion of a review by Haake
and colleagues. 相似文献
