The clinical and laboratory data of 24 cases misdiagnosed as spondyloarthropathy in recent 3 years were comparatively and retrospectively analyzed. The diagnostic accuracy of the European Spondyloarthropathy Study Group (ESSG) criteria, Amor criteria, and the combination of them in these misdiagnosed cases was also analyzed.
The final diagnoses of these 24 cases were listed below: four malignant tumors (retroperitoneal adipose sarcoma, advanced gastric carcinoma, ovarian papillary epithelioma, acute lymphocytic leukemia), six benign tumors (two parathyroid adenoma with hyperparathyroidism, one intraspinal lipoma, intraspinal ependymomas, sacral tubulocyst, and intraspinal schwannoglioma, respectively). The other 14 cases included Fer-1 concentration fibromyalgia syndrome (3), osteitis condensans (3), diffuse idiopathic skeletal hyperostosis (2), lumbar intervertebral disk protrusion (1), congenital scoliosis (1), Wilson’s disease (1),
ochronosis (1), Fanconi syndrome (1) and hypophosphatemic rachiopathy (1). Among patients with tumor, all except three patients had persistent low back pain without morning stiffness, which aggravated at night and could not be relieved by rest or exercise. The symptoms could not be relieved by administration Dinaciclib of multiple nonsteroidal anti-inflammatory drugs. Eleven patients had inflammatory low back pain defined by Calin. Of the total misdiagnosed cases, 54.17-83.33% could be prevented by application of ESSG criteria or Amor criteria, or a combination of them. From the data, we could see that the clinical features of different diseases with low back pain were different from each other and from those of spondyloarthropathy. The various criteria for spondyloarthropathy may be more effective in combination, along with other clinical information like these clinical features.”
“Background: The chromosome preparation is a crucial step for obtaining satisfactory results in molecular cytogenetic researches.
The preparation of plant chromosomes for molecular cytogenetic purposes remains a challenge for some species. In contrast Volasertib to human chromosome preparation, the processes occurring during plant chromosome preparation and causing chromosome spreading are still poorly understood.
Results: We studied the dynamics of plant chromosome spreading after dropping cell suspension on slides. We showed that steam stimulates cytoplasm hydrolysis and rapid chromosome spreading and that chromosomes stretch during this chromosome spreading. Based on these observations, we developed a novel method, named “”SteamDrop”", for the preparation of well-spread mitotic and pachytene chromosomes and successfully used it for 28 plant species with large and small chromosomes. We applied cell suspensions in ethanol instead of the commonly used ethanol/acetic acid fixative.
