Acne-associated spondylarthropathy: radiographic features 总被引:3,自引:0,他引:3
Experience with six patients with severe acne and associated axial and peripheral arthritis is described. Four of the patients had a dermatologic triad of severe acne, hidradenitis suppurativa, and dissecting cellulitis of the scalp, the so-called follicular occlusion triad. All were black men with episodic peripheral arthropathy and low back pain. One had inflammatory bowel disease. Rheumatoid factor and HLA-B27 were absent in five patients who had these determinations. An erosive and proliferative arthritis of the axial and appendicular skeleton is described. The radiographic findings were indistinguishable from those of the seronegative spondylarthropathies. We found no previous reports in the radiologic literature describing this articulocutaneous entity. 相似文献

The 3‐D gradient‐echo (GRE) sequence allows thinner sections and better resolution of biliary obstruction. When the presence of biliary obstruction is identified using magnetic resonance cholangiopancreatography, the addition of the 3‐D GRE sequence may be helpful for diagnosing biliary obstruction. By showing the changes in the bile duct wall, within the duct lumen and around the bile duct, this technique can be helpful for distinguishing benign from malignant stricture as well as a stone from an enhancing intraluminal mass. 相似文献

In the histomorphological grading of prostate carcinoma, pathologists have regularly assigned comparable scores for the architectural Gleason and the now‐obsolete nuclear World Health Organization (WHO) grading systems. Although both systems demonstrate good correspondence between grade and survival, they are based on fundamentally different biological criteria. We tested the hypothesis that this apparent concurrence between the two grading systems originates from an interpretation bias in the minds of diagnostic pathologists, rather than reflecting a biological reality. Three pathologists graded 178 prostatectomy specimens, assigning Gleason and WHO scores on glass slides and on digital images of nuclei isolated out of their architectural context. The results were analysed with respect to interdependencies among the grading systems, to tumour recurrence (PSA relapse > 0.1 ng/ml at 48 months) and robust nuclear morphometry, as assessed by computer‐assisted image analysis. WHO and Gleason grades were strongly correlated (r = 0.82) and demonstrated identical prognostic power. However, WHO grades correlated poorly with nuclear morphology (r = 0.19). Grading of nuclei isolated out of their architectural context significantly improved accuracy for nuclear morphology (r = 0.55), but the prognostic power was virtually lost. In conclusion, the architectural organization of a tumour, which the pathologist cannot avoid noticing during initial slide viewing at low magnification, unwittingly influences the subsequent nuclear grade assignment. In our study, the prognostic power of the WHO grading system was dependent on visual assessment of tumour growth pattern. We demonstrate for the first time the influence a cognitive bias can have in the generation of an error in diagnostic pathology and highlight a considerable problem in histopathological tumour grading.

Only hydrosalpinges visible on ultrasound are associated with reduced implantation and pregnancy rates after in-vitro fertilization 总被引:3,自引:10,他引:3

A retrospective analysis of clinical and laboratory data was made of all
in-vitro fertilization (IVF) patients with tubal pathology who had their
first ever embryo transfer cycle between January 1st, 1992 and September
1st, 1996. The aim of the study was to determine the effect of the presence
of a hydrosalpinx, whether or not visible by ultrasound, on pregnancy,
multiple pregnancy and implantation rates in our patient population. The
IVF success rate was also analysed by calculating cumulative ongoing
pregnancy rates of the same patient group using the lifetime table
approach. In the presence of an ultrasound-visible hydrosalpinx, rates of
pregnancy and multiple pregnancy appeared reduced, but the differences were
not significant. The rates of implantation, clinical implantation and
ongoing implantation were significantly lower in the presence of an
ultrasound- visible hydrosalpinx (odds ratios 0.33-0.46, C.I. 0.21-0.96).
The cumulative chance of achieving an ongoing pregnancy after one or more
IVF cycles was significantly reduced in the presence of an ultrasound-
visible hydrosalpinx (relative hazard 0.36, C.I. 0.22-0.59). In the
presence of a hydrosalpinx not visible by ultrasound the IVF outcome was
not reduced. This retrospective study confirms that patients with
hydrosalpinges have an impaired IVF outcome. Unique to this study and
previously unobserved is the finding that there is a subgroup of patients
with hydrosalpinges, those with ultrasound-visible hydrosalpinges, which is
exclusively responsible for this impaired outcome.
