Purpose: This study aimed to analyse laboratory values according to fever duration, and evaluate the relationship across these values during the acute phase of Kawasaki disease (KD) to aid in the early diagnosis for early-presenting KD and incomplete KD patients.

Methods: Clinical and laboratory data of patients with KD (n=615) were evaluated according to duration of fever at presentation, and were compared between patients with and without coronary artery lesions (CALs). For evaluation of the relationships across laboratory indices, patients with a fever duration of 5 days or 6 days were used (n=204).

Background: After interbody cage implantation for posterior or transforaminal lumbar interbody fusion (PLIF or TLIF) spinal fusion surgery, pseudoarthrosis can develop. However, there are several shortcomings of the posterior approach if the interbody cage requires removal. Therefore, an anterior approach may be useful.

Objective: Several surgical methods have been reported for treatment of ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine. Despite rapid innovation of instruments and techniques for spinal surgery, the postoperative outcomes are not always favorable. This article reports a minimally invasive anterior decompression technique without instrumented fusion, which was modified from the conventional procedure.

Article Synopsis
  • Kawasaki disease (KD) has become more common in Korea, and a study compared clinical and laboratory features of KD patients from two different time periods: 2000-2004 and 2010-2014.
  • The analysis included 615 patients, revealing that patients in the later period (group B) showed a higher percentage of incomplete KD and lower instances of coronary artery lesions, while also having milder laboratory findings, such as lower levels of C-reactive protein.
  • Overall, the study suggests that the clinical presentation of KD has become milder over the past decade, indicating changes in how the disease manifests among recent patients compared to those from earlier years.

Purpose: Although a significant number of reports on new therapeutic options for refractory Kawasaki disease (KD) such as steroid, infliximab, or repeated intravenous immunoglobulin (IVIG) are available, their effectiveness in reducing the prevalence of coronary artery lesions (CAL) remains controversial. This study aimed to define the clinical characteristics of patients with refractory KD and to assess the effects of adjuvant therapy on patient outcomes.

Methods: We performed a retrospective study of 38 refractory KD patients from January 2012 to March 2015.

Objective: Malignant middle cerebral artery (MCA) infarction occurs in 10% of all ischemic strokes and these severe strokes are associated with high mortality rates. Recent clinical trials demonstrated that early decompressive craniectomy reduce mortality rates and improves functional outcomes in healthy young patients (less than 61 years of age) with a malignant infarction. The purpose of this study was to assess the efficacy of decompressive craniectomy in elderly patients (older than 70 years of age) with a malignant MCA infarction.

Aneurysmal bone cyst (ABC) is benign vascular lesion destructing the cortical bone by the expansion of the vascular channel in the diploic space that usually involve long bone and spine. Orbital ABC is rare and the clinical symptoms deteriorate rapidly after initial slow-progression period for a few months. A 12-year-old female patient visited ophthalmologist due to proptosis and upward gaze limitation of the right eye, and orbital mass was noted in the upper part of right eye on orbital MRI.
