Background: The normal vertebral anatomy of Korean raccoon dogs and their variants require research attention as a prerequisite for identifying pathologies and anomalies. Objectives: This retrospective study aimed at describing the vertebral formula and congenital vertebral anomalies in Korean raccoon dogs (Nyctereutes procyonoides koreensis). Methods: Radiographs of 82 raccoon dogs (42 males, 40 females) acquired from May 2013 to June 2020 in the Gangwon Wildlife Medical Rescue Center were reviewed to evaluate the cervical, thoracic, and lumbar vertebrae of the spine. Results: Normal morphology of all vertebrae was observed in 50 of the 82 raccoon dogs, and the vertebral formula was cervical 7, thoracic 13, and lumbar 7. Congenital vertebral anomalies were found in 32 raccoon dogs: transitional vertebrae (TV) in 31 and block vertebrae in 2. Two raccoon dogs had 2 types of vertebral anomalies: one had TV and block vertebra, and the other had 2 types of TV. Twenty-nine raccoon dogs had thoracolumbar TV (TTV) and 3 had lumbosacral TV. TTV was morphologically classified into 4 different types:unilateral extra-rib in 5 raccoon dogs, bilateral extra-ribs in 14, bilateral elongated transverse processes in 4, and an asymmetric mixed formation of extra-rib with elongated transverse process in 6. Conclusions This study showed that TTV is common in Korean raccoon dogs, and that the vertebral formula is relatively diverse. The bilateral extra-ribs type TTV is the most common variant, which is almost similar to normal rib to be confused the radiographic evaluation.

Sotos syndrome is a rare sporadic genetic disorder characterized by pathognomonic facial features, motor developmental delay induced by hypotonia, learning difficulties, and cardiac and renal anomalies. This report describes the case of a 4-year-old child with Sotos syndrome who underwent a right hydrocelectomy under general anesthesia. We report our experience with airway management, choice of anesthetic drugs, and other anesthetic implications in Sotos syndrome.

INTRODUCTION: Skeletal homeostasis is normally maintained by the stability between bone formation by osteoblasts and bone resorption by osteoclasts. However, the correlation between the inflammatory reaction and osteoblastic differentiation of cultured osteoprogenitor cells has not been fully investigated. This study examined the effects of inflammatory cytokines on the osteoblastic differentiation of cultured human periosteal-derived cells. MATERIALS AND METHODS: Periosteal-derived cells were obtained from the mandibular periosteum and introduced into the cell culture. After passage 3, the periosteal-derived cells were further cultured in an osteogenic induction Dulbecco's modified Eagle's medium (DMEM) medium containing dexamethasone, ascorbic acid, and beta-glycerophosphate. In this culture medium, tumor necrosis factor (TNF)-alpha with different concentrations (0.1, 1, and 10 ng/mL) or interleukin (IL)-1beta with different concentrations (0.01, 0.1, and 1 ng/mL) were added. RESULTS: Both TNF-alpha and IL-1beta stimulated alkaline phosphatase (ALP) expression in the periosteal-derived cells. TNF-alpha and IL-1beta increased the level of ALP expression in a dose-dependent manner. Both TNF-alpha and IL-1beta also increased the level of alizarin red S staining in a dose-dependent manner during osteoblastic differentiation of cultured human periosteal-derived cells. CONCLUSION: These results suggest that inflammatory cytokines TNF-alpha and IL-1beta can stimulate the osteoblastic activity of cultured human periosteal-derived cells.

OBJECTIVE: This study aimed to investigate factors associated with incomplete occlusion of a cerebral aneurysm detected by indocyanine green videonangiography (ICG-VA) following aneurysm clipping. METHODS: We performed surgery on 135 patients with 151 intracranial aneurysms over a 1-year period. Included was an aneurysm more than 3 mm in size, the dome of which was sufficiently exposed and clipped permanently with one clip. Following ICG-VA, aneurysms were divided into a delayed-filling group and a no-filling group. Retrospective comparisons of the clip force, blade length and width, neck and dome size of the aneurysm, diameter of the parent artery, presence of atherosclerosis in the aneurysm neck, and systolic blood pressure during ICG-VA were made between the two groups. RESULTS: Eight of 31 aneurysms in 29 patients showed delayed filling of contrast. The clip force in the delayed-filling group was lower than in the no-filling group and the atherosclerosis of the aneurysm neck differed between the two groups (P<0.05). Blade width in the delayed-filling group was also significantly lower than in the no-filling group (P<0.05). Following adjustment for atherosclerosis of the aneurysm neck, clip force and blade width in the delayed-filling group was even lower. Incomplete passage of the clip tip was observed in four aneurysms, weak clip force in three, and a slit between clip blades in one. After booster clipping or clip reposition, neither aneurysm regrowth nor recanalization was observed during 6 months of follow-up. CONCLUSION: Closing force, blade width, tip position, and remnant slit are important for incomplete occlusion of an aneurysm.
