Symptomatic Postoperative Discal Pseudocyst After Percutaneous Endoscopic Interlaminar Discectomy: Case Report and Literature Review.

Background: A postoperative discal pseudocyst (PDP) is a cystic lesion that is formed in the operation area of the intervertebral disc, leading to recurrence or even worse symptoms. To our knowledge, to date, there is no research focusing specifically on PDP following percutaneous endoscopic interlaminar discectomy (PEID).

Case Presentation: We present the case of a 27-year-old man with L S intervertebral disc herniation who was treated with PEID after failed conservative treatment.

Accuracy of magnetic resonance imaging signal intensity ratio measurements in the evaluation of multifidus muscle injury and atrophy relative to that of histological examinations.

Study Design: A matched-pairs animal study.

Objective: To confirm the accuracy of magnetic resonance imaging (MRI) as a means of evaluating edema and fat degeneration of the multifidus muscle by comparing measurements made using MRI with those made using histological examination.

Summary Of Background Data: MRI is considered a reliable means of evaluating multifidus muscle edema and fat degeneration.

High expression of IGFBP7 in fibroblasts induced by colorectal cancer cells is co-regulated by TGF-β and Wnt signaling in a Smad2/3-Dvl2/3-dependent manner.

Fibroblasts in the tumor microenvironment are a key determinant in cancer progression and may be a promising target for cancer therapy. Insulin-like growth factor binding protein 7 (IGFBP7) is known as a tumor suppressor in colorectal cancer (CRC). The present study investigated the inductive mechanism of IGFBP7 expression in fibroblasts by supernatant from the CRC cell line, SW620.
