AI Article Synopsis

  • Chronic recurrent multifocal osteomyelitis (CRMO) is a rare inflammatory disorder that leads to unpredictable flare-ups and remissions, with no established randomized-controlled treatment options.
  • First-line treatments include non-steroidal anti-inflammatory drugs (NSAID) and glucocorticoids, with bisphosphonates and biologic agents like anti-TNF therapy showing promising results.
  • In a case study involving three children with CRMO treated with various medications, including etanercept, all showed clinical improvement, supporting the potential use of etanercept for severe, persistently active cases.

Article Abstract

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare non-infectious inflammatory disorder with unpredictable clinical course, characterized by acute exacerbations and spontaneous remissions. There are no randomized-controlled trials about treatment options. Non-steroidal anti-inflammatory drugs (NSAID) are the first-line treatment option; glucocorticoids seem to be effective; positive outcomes have been obtained with bisphosphonates. In the last few years successful use of biologic agents like anti-TNF agents has been reported. We report the cases of 3 children suffering from CRMO who were treated with NSAID, steroid, bisphosphonates and eventually received etanercept and 1 case without vertebral involvement treated with etanercept after NSAID and steroid; all cases showed clinical improvement. The mean ages at symptoms onset and diagnosis were 8 and 10 years and 10 months, respectively. Two patients presented with back pain and three had vertebral lesions. Mean interval from diagnosis to the onset of anti-TNF treatment was 14 months. According to our small experience, we suggest considering therapy with etanercept for the treatment of severe cases with persistently active disease despite multiple treatments.

Background: Robotic hepatectomy has been increasingly adopted for the treatment of hepatocellular carcinoma (HCC). However, the ideal technique of parenchymal transection in robotic hepatectomy has been a matter of ongoing debate in literature.

Patients And Methods: In this video, we demonstrate the technique of robotic anatomical segment VIII resection using the scissor hepatectomy technique for parenchymal transection on a 75-year-old male patient with a solitary HCC lesion.

Endometriosis is a chronic disease that affects around 10% of reproductive age women worldwide and a common cause of infertility. One of its manifestations is ovarian endometriomas, which are present in 17-44% of endometriosis patients. Endometriomas can impair fertility by mechanical stretching and local inflammation, promoting oxidative stress in the surrounding ovarian cortex that could lead to apoptosis and necrosis of early follicles.

Background/purpose: Oral lichen planus (OLP) is a chronic inflammatory disorder characterized by basement membrane disruption, which plays a crucial role in its pathogenesis. Matrix metalloproteinases (MMPs), a group of proteolytic enzymes, contribute to the degradation of the basement membrane. The specific MMPs secreted by keratinocytes in OLP lesions and relevant regulatory mechanisms are not fully understood.

The skeletal system, composed of bones, muscles, joints, ligaments, and tendons, serves as the foundation for maintaining human posture, mobility, and overall biomechanical functionality. However, with ageing, chronic overuse, and acute injuries, conditions such as osteoarthritis, intervertebral disc degeneration, muscle atrophy, and ligament or tendon tears have become increasingly prevalent and pose serious clinical challenges. These disorders not only result in pain, functional loss, and a marked reduction in patients' quality of life but also impose substantial social and economic burdens.
