Objectives: This study aimed to determine the association between metabolic syndrome (MetS) and the incidence of colorectal cancer (CRC) in Korean women with obesity. Methods: Cancer-free women (n=6 142 486) aged 40-79 years, who underwent National Health Insurance Service health examinations in 2009 and 2010 were included. The incidence of CRC was followed until 2018. The hazard ratio (HR) of MetS for the incidence of colon and rectal cancer was analyzed according to body mass index (BMI) categories, adjusting for confounders such as women’s reproductive factors. In addition, the heterogeneity of associations across BMI categories was assessed. Results: Women with MetS were at increased risk of colon and rectal cancer compared to women without MetS (HR, 1.20; 95% confidence interval [CI], 1.16 to 1.23 and HR,1.15; 95% CI, 1.11 to 1.20), respectively. The HR of MetS for colon cancer across BMI categories was 1.12 (95% CI, 1.06 to 1.19), 1.14 (95% CI, 1.08 to 1.20), and 1.16 (95% CI, 1.12 to 1.21) in women with BMIs <23.0 kg/m2, 23.0-24.9 kg/m2, and ≥25.0 kg/m2, respectively. The HR of MetS for rectal cancer across corresponding BMI categories was 1.16 (95% CI, 1.06 to 1.26), 1.14 (95% CI, 1.05 to 1.23), and 1.13 (95% CI, 1.06 to 1.20). The heterogeneity of associations across BMI categories was not significant in either colon or rectal cancer (p=0.587 for colon cancer and p=0.927 for rectal cancer). Conclusions Women with MetS were at increased risk of colon and rectal cancer. Clinical and public health strategies should be considered for primary CRC prevention with an emphasis on improving women’s metabolic health across all BMI groups.

Discoid meniscus is a congenital morphological variable anomaly of meniscus which is often asymptomatic. Arthroscopic surgeries on 91 symptomatic lateral discoid menisci of 84 patients were performed at the Department of Orthopedic Surgery, Seoul National University Hospital during the period of Jan. 1987 to Jan. 1994, which equals 19.2% of arthroscopic meniscectomies performed. Follow up was done from minimum of 1 year to maximum of 8 years, with an average period of 3 years and 10 months. Retrospective study was done with the review of clinical records, roentgenograms, MRI, and arthroscopic findings on recorded videotapes to evaluate the clinical and radiological features, results of arthroscopic treatment and possible prognostic factors. The followings are the results: 1. The lateral discoid meniscus encompassed 19.2% of arthroscopic meniscectomies performed at the same period, which was relatively high incidence. Arthroscopic partial and subtotal menis- cectomy resulted in satisfactory results. 2. Since 8 (11%) knees were not diagnosed preoperatively as discoid meniscus due to type being incomplete or torn meniscus displacement, these points should be considered with clinical findings at diagnosis of discoid meniscus. 3. 34.9% of 83 menisci with tear had previous trauma history which showed high vulnerability to tear. Discoid menisci without tears but with grade II intrasubstance increased signal and symptoms were treated with arthroscopic meniscectomy and showed good results. Therefore discoid menisci without tears should be considered of arthroscopic meniscectomy in the presence of clinical symptoms and MRI findings. 4. Lysholm total and pain scores were significantly improved at postop. 1 year and at the final follow up with p<0.05. Factors such as degenerative changes, sex, age, duration of preoperative symptoms, presence of tears and types of meniscectomy gave no significant influence on the results and the prognosis.

Neurenteric cyst is an extremely rare developmental cyst of the central nervous system. It is lined withintestinal epithelium and is usually found in the subarachnoid space of the cervical and thoracic spine. We reporta case of intracranial neurenteric cyst in a 40-year-old man, and describe the MRI findings. This modality showeda large cyst, ventral to the pons and extending bilaterally to the cerebellopontine angles and craniovertebraljunction;its signal was hyperintense on both T-1and T2-weighted images and there is no enhancement on postcontrastT1-weighted images.

Methods: Radiograms of the 11 study subjects (six men and five women), aged 22–90 years who visited the outpatients’ clinic for various neck complaints without trauma history were examined. C4–5 synostosis was an incidental finding in all the subjects. Results: All the fused bodies were inwaisted and had anterior caudal breaking but no interior corporal flaring. Adjacent segment disease was not found in eight patients aged <40 years. Disk degeneration was found at C3–4 and C5–6 in three patients each and at C6–7 in two patients. Disk degeneration was limited to the adjacent segments. Conclusions Degenerative disk changes are associated with the natural aging process, and the corporal morphology of the fused vertebral becomes inwaisted similar to that in the single vertebrae.

Coronary artery anomalies are diagnosed in 0.6 to 1.5% of patients who undergo coronary angiography (CAG). They may present with life threatening conditions but are generally asymptomatic. Recognition and adequate visualization of the anomaly is essential for correct management of the condition. However, in some cases the exact orifice and course of an anomalous coronary vessel cannot be selectively identified by CAG. In this report, a 54-year-old man was admitted to the hospital with acute inferior myocardial infarction and had an anomalous origin of the left circumflex coronary artery (LCX) from the first diagonal branch (D1). In CAG, the right CAG showed no significant stenosis and fortunately we found an anomalous origin of the LCX from the D1. The course of LCX was precisely established by 64-slice multi-detector computed tomography.

BACKGROUND: Intertrochanteric fractures of the femur are the most common type of fracture, and are an increasing occurrence due to the aging of the population. The objectives of our study are to predict the fate of intertrochanteric fractures treated with intramedullary hip nails by assessing the postoperative fracture stability utilizing the newly developed scoring system, and to help rehabilitate these patients. METHODS: Eighty-two patients with intertrochanteric fractures that were treated with intramedullary hip nails between December, 2004 and January, 2011 were subjected to this study. The patients who could be followed for a minimum of one year postoperatively were enrolled. The immediate postoperative conditions were determined by radiograms: reduction status (3 parameters/4 points: contact accuracy of posteromedial cortex, severity of angulation, and distraction), fixation status (3 parameters/3 points: tip-apex distance, location of tip of the lag screw, entry point of the intramedullary nail), and fracture type (1 parameter/1 point: stable or unstable type by the Kyle's classification). Postoperative reduction loss and fixation failure were checked by radiograms taken at a minimum 3 months postoperative. RESULTS: Reduction loss and fixation failure were observed in 14 consecutive patients (17%). The fixation failure rate was 100% (2 patients) in score 1, 60% (3 out of the 5 patients) in score 2, 39% (3 out of the 8 patients) in score 3, and 50% (4 out of the 8 patients) in score 4 groups. There were fixation failures only in 1 out of 13 patients with score 5, and in 1 out of 18 patients with score 6. There was no fixation failure in 17 patients with score 7 and 11 patients with score 8. CONCLUSIONS: Maintenance of the fracture reduction by the stable fixation in the patient scores over 5 could be predicted by the postoperative radiograms.

The traffic accident was one of most common cause for the facial bone fracture. When it involved the midfacial structures, the nasal bone fracture was usually shown. If the reduction was not done in time, it would result in facial deformity. Simple case could be corrected by simple rhinoplasty. However, severe cases would require more invasive technique. We used triangular osteotomy included the nasal bones, the vomer, and the medial wall of maxilla for the correction of post-traumatic nasal deformity and reported the result with the review of literatures.

Pyogenic spondylitis involving only the posterior element of a vertebra is rare. To the best of our knowledge, there have been no reports of osteomyelitis of the transverse process. We report here on a 45-year-old male with a one month history of swelling associated with lower back pain. The magnetic resonance imaging showed a paraspinal soft tissue mass, and computed tomography revealed a fine osteolytic lesion in the right transverse process of the 5th lumbar spine, and this was all consistent with chronic osteomyelitis. A mixed staphylococcal infection was identified. Open drainage, resection of the transverse process and intravenous injection of anti-staphylococcal antibiotics resolved the back pain and reduced the erythrocyte sedimentation rate to normal. Pyogenic osteomyelitis of the transverse process is extremely rare, which can cause a misdiagnosis or a delayed diagnosis. Careful consideration of this disease is needed when evaluating patients who complain of back pain.
