Postoperative atlantoaxial rotatory subluxation (AARS) is a rare complication that develops almost exclusively in children following oropharyngeal and otologic surgeries, proposing that oropharyngeal inflammatory responses and excessive head rotation are responsible factors. However, there have been no reports of AARS after excision of a nevus on the head and neck. Here, we present two cases of AARS following limited head rotation during simple nevus excision. Patient 1, a 9-year-old girl, complained of neck pain and limited range of motion after excision of the nevus on the neck. After 2 months, computed tomography and magnetic resonance imaging finally revealed AARS with a ruptured transverse atlantal ligament. A month of halo traction was required for the treatment. Patient 2, an 11-year-old girl, presented with immediate pain and limited neck extension after tissue expander insertion under the upper chest and excision of the nevus on her left cheek. The diagnosis was promptly made using cervical spine radiography. A cervical collar was applied for 1 month. Both patients recovered without any complications after treatment. This report highlights the importance of suspicion for AARS after surgery regardless of surgical duration or amount of head rotation.

Objectives : The purpose of this study is to investigate the effecacy of Korean medical treatments on cervical myelopathy patient diagnosed by magnetic resonance imaging(MRI). Methods : The patient was treated by Korean medical treatments including acupunture, pharmacopuncture, herbal medicine, cervical traction technique of Chuna treatment. To evaluate the change of MRI view, slipped disc ratio and A-P compression ratio were used. The improvement of the clinical symptoms was observed by Score of pain part and Nurick grade. Results : After treatment, patient's score of pain part, Nurick grade were decreased and slipped disc ratio, A-P compression ratio were also improved. Conclusions : The Korean medical treatments might be an effective method to improve the clinical symptoms and radiological view of cervical myelopathy.

The fruits of Cornus kousa Burg. were extracted with 80% aqueous methanol (MeOH) and the concentrated extract was partitioned with ethyl acetate (EtOAc), n-butanol (n-BuOH), and $H_2O$. From the EtOAc traction, 5 triterpenoids were isolated through repeated silica gel ($SiO_2$), octadecyl silica gel (ODS), and Sephadex LH-20 column chromatography (c.c.). These compounds were determined to be ursolic acid (1), corosolic acid (2), taraxasterol (3), betulinic acid (4), and betulinic aldehyde (5) on the basis of their spectroscopic data including electronic ionization mass spectrometry, ultraviolet spectroscopy, infrared spectroscopy, and nuclear magnetic resonance. This is the first reported isolation of these compounds from this plant. Also, compounds 1, 3, 4, and 5 show a relatively high inhibitory activity against human acyl-CoA: cholesterol acyltransferase-1 (hACAT-1) with inhibition values of $52.8{\pm}0.7$, $91.1{\pm}0.4$, $93.0{\pm}0.7$, and $96.2{\pm}0.2%$ at a concentration of $100{\mu}M$, respectively.

Torticollis is an abnormal, asymmetric head or neck position which usually caused by imbalance of paracervical muscles. The traumatic torticollis can be caused by following events; atlantoaxial rotatory subluxation, atlantoaxial dislocation, cervical vertebral fractures, and injury to the cervical musculature. Especially, acute traumatic atlantoaxial rotatory subluxation usually presents limitation of cervical range of motion without pain or neurologic deficit. We report a case of a 58 year-old man who developed the acute atlantoaxial rotatory subluxation right after the chiropractic therapy, which induced the limitation of cervical range of motion to 52.5% of normal range. The magnetic resonance image revealed the facture of the odontoid process and the partial injury in transverse ligaments of the atlas. He underwent intramuscular botulinum toxin injection and 10 days of continuous cervical traction 15 hours a day using a 5 kg weight. The range of the cervical motion restored up to 90.2% of normal range.

During sports activity, rectus femoris muscle can be commonly injured as the quadriceps contracts forcefully to extend the knee and flex the hip, and rectus femoris muscle has a high percentage of type II muscle fibers which enable it to produce rapid forceful activity and the muscle is the only biarticular muscle of the quadriceps. Avulsion fractures by the traction of rectus femoris from the anterior inferior iliac spine in children are often reported. Rarely, complete rupture of proximal musculotendinous junction of rectus femoris muscle in adult may occurs by chronic repetitive stimulation and may mimic soft tissue neoplasm in the case of no history of antecedent trauma. However, there has been no report of acute complete rupture of origins of the rectus femoris muscle during relay race till now. So, we report a case of acute complete rupture of origins of the rectus femoris muscle occurred during relay race in middle-aged man, diagnosed by magnetic resonance image and treated by surgical repair with review of current literature.
