Case Reports
An unusual case of sclerosing angiomatoid nodular transformation: radiological and histopathological analyses.
Sclerosing angiomatoid nodular transformation (SANT) is a rare benign primary vascular lesion of the spleen. Its etiology is still debated. Radiological characteristics are less known, although there are some reports regarding histopathological features ofSANT. ⋯ Microscopically, it was composed of angiomatoid nodules separated by central stellate fibrous stroma and fibrous septa. The contrast enhancement pattern was described as centrally hypovascular, radially progressive centripetal vascular contrast enhancement, called a spoke-wheel pattern in previously reported cases. We present CT and MRI findings and their correlation with histopathological findings of a case of unusual symptomatic SANT.

Irritable bowel syndrome (IBS), a functional disorder of the bowel, has been thought to result from immune activation. The aim of this study was to evaluate macrophage migration inhibitory factor (MMIF) and monocyte chemotactic protein-1 (MCP-1) levels in IBS patients. ⋯ These results show that alterations in MMIF and MCP-1 affect the proinflammatory process. They also suggest that MMIF and MCP-1 may play a substantial role in IBS.

To evaluate the changes in the number of NADPH diaphorase (NADPH-d) stained neurons in the vagal nuclei in a chronic esophagitis model. ⋯ The increased nitric oxide expressions in the dorsal vagal nucleus and nucleus tractus solitarius are most probably due to adaptive changes to disturbed esophageal motility and mucosal damage.

To evaluate the relation between biochemical recurrence (BCR) of prostate cancer and the extent of positive surgical margins (PSMs), Gleason score (GS) of the tumor at the margins, and preoperative prostate-specific antigen (PSA) levels. ⋯ High preoperative PSA levels, PSMs, and tumors with high GS at the margins have a poor prognostic impact, and they correlate with a higher rate of BCR. Close follow-up of patients with PSMs with high GS and high levels of preoperative PSA is recommended.

To develop a novel polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) protocol using a new genomic marker sequence and a novel set of restriction enzymes in order to detect and discriminate 2 Echinococcus species, E. granulosus and E. multilocularis, found in formalin-fixed paraffin-embedded (FFPE) human tissues. ⋯ In this PCR-RFLP protocol, use of any single restriction enzyme is enough for the discrimination of E. granulosus and E. multilocularis. The PCR-RFLP protocol can be potentially used for the discrimination of 5 other Echinococcus species: E. oligarthus, E. shiquicus, E. ortleppi, E. canadensis, and E. vogeli.
