The intramedullary nailing for humeral shaft fractures has become popular fixation method. It affords less invasive procedure, good stability and early rehabilitation. However many complications were reported such as nonunion, pain and motion limitation of shoulder. We managed 33 patients using interlocking intramedullary nail for the humeral shaft fractures, and nonunion occurred in 9 patients. We reviewed these 9 cases and analyzed the relationship between the nonunions and the fracture sites as well as fracture types. The results were as follows; 1. Nonunion occurred in 9 patients of 25 patients treated closed reduction, but did not occur in 8 patients treated open reduction. 2. The union was obtained in all 6 patients with proximal one third fracture. But nonunion occurred in 6 patients of 19 patients with middle one third fracture and in 3 patients of 8 patients with distal one third fracture. 3. Nonunion after interlocking nails for humeral shaft fractures did not occur in all 6 spiral fracture patients. Nonunion occurred in 5 patients of 8 comminuted fracture patients, in 3 patients of 6 transverse fracture patients and in 1 patient of 3 oblique fracture patients with below the middle one third of humerus. Our study showed that the high rate of nonunion occurred in the comminuted, transverse and oblique fracture below the middle one third of humerus. On the basis of these findings, we recommend that closer attention should be paid when choose the fixation method in these types of the humeral shaft fractures.

OBJECTIVE: To investigate nationwide statistics on flow-diverting stent usage for cerebral aneurysm treatment and related mortality data.METHODS: We requested data extraction from the National Health Insurance Service claims database using electronic data interchange codes (J3207064, J3207073). Patient and hospital information as well as death statistics were collected from the database.RESULTS: A total of 169 procedures were performed using flow-diverting stents for cerebral aneurysm treatment from November 2014 to December 2016 in Korea. The majority of primary diagnosis was unruptured intracranial aneurysm. During the study period, nine subjects died, including one patient initially diagnosed with subarachnoid hemorrhage. The crude mortality rate was 5.3%. Five patients died within one month after the procedure; therefore, the estimated periprocedural mortality rate was 3.0±1.3%. The mortality rate as of the last day of 2016 was 6.3±2.1%.CONCLUSION: In a 171 person-year follow-up in a Korean series, nine deaths occurred after flow-diverting stent treatment. The crude mortality rate in Korea (5.3%) was higher than that reported in a previous meta-analysis (3.8%).

According to published reports, a common feature of xanthogranulomatous cholecystitis is the presence of intramural hypoattenuated nodules in thickened gallbladder wall. These nodules can, however, also be seen in pathological conditions such as acute cholecystitis, hyperplastic cholecystoses (cholesterolosis and adenomyomatosis), gallbladder cancer, and other inflammatory diseases such as tuberculosis. Retrospective review of the abdominal CT findings in 622 patients who for various reasons underwent cholecystectomy during a one-year period showed that intramural nodules were present in 60. In this pictorial essay we illustrate the imaging features of the many different pathological conditions which give rise to intramural hypoattenuated nodules in thickened wall of the gallbladder, correlating these features with the histopathological findings.

Radiation-induced morphea in breast cancer patients who have been treated with radiotherapy is now a well-recognized clinical entity. It is characterized by marked sclerosis, erythema and pigmentary changes. We report a case of a 55-year-old woman who presented with erythematous indurated patches on the right shoulder and back area where radiation therapy had been given for breast cancer. Histopathologic examination revealed marked thickening of the dermis, consisting of sclerotic, densely aggregated collagen bundles.

Ovarian malignancy can rarely present as a colonic mass and simulate colon cancer. Mullerian anomalies are congenital anatomic abnormalities of the female internal genitalia, of which a unicornuate uterus is a rare subtype. Several cases of gynecologic malignancies arising in Mullerian anomalies have been described. However, an ectopic ovarian malignancy in conjunction with a unicornuate uterus has never been reported. We report a case of ectopic ovarian mixed epithelial tumor, a very rare subtype of ovarian epithelial tumor, which presented as a colonic mass simulating colon cancer in a woman with a unicornuate uterus.

PURPOSE: Little is known about the clinical value of peripheral blood immune profiling. Here, we aimed to identify colorectal cancer (CRC)-related peripheral blood immune cells and develop liquid biopsy-based immune profiling models for CRC diagnosis. METHODS: Peripheral blood from 131 preoperative patients with CRC and 174 healthy controls was analyzed by flow cytometry and automated hematology. CRC-related immune factors were identified by comparing the mean values of immune cell percentages and counts. Subsequently, CRC diagnostic algorithms were constructed using binary logistic regression. RESULTS: Significant differences were observed in percentages and counts of white blood cells, lymphocytes, neutrophils, regulatory T cells, and myeloid-derived suppressor cells (MDSCs) of patients and controls. The neutrophil/lymphocyte and Th1/Th2 ratios were also significantly different. Likewise, the percentages and counts of peripheral blood programed death 1, cytotoxic T lymphocyte antigen 4, B-and T-lymphocyte attenuator, and lymphocyte activation gene-3 were higher in patients with CRC. The binary logistic regression model included 12 variables, age, CD3+%, NK%, CD4+CD279+%, CD4+CD25+%, CD4+CD152+%, CD3+CD366+%, CD3+CD272+%, CD3+CD223+%, CD158b−CD314+CD3−CD56+%, Th2%, and MDSCs cells/µL, for the prediction of cancer. Results of retrospective and prospective evaluation of the area under the curve, sensitivity, and specificity were 0.980 and 0.940, 91.53% and 85.80%, and 93.50% and 86.20%, respectively. CONCLUSION: Peripheral blood immune profiling may be valuable in evaluating the immunity of CRC patients. Our liquid biopsy-based immune diagnostic method and its algorithms may serve as a novel tool for CRC diagnosis. Future largescale studies are needed for better characterization of its diagnostic value and potential for clinical application.

BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing disease with genetic and environmental background. Many factors may act as triggers and affect the course of the disease. However, little is known about the factors affecting the disease severities in Korean childhood AD. OBJECTIVE: The aim was to document the distinct characteristics of childhood AD in Korea and to determine which manifestations are prone to be present in the settings of different severity of the disease. METHOD: The clinical manifestations, past medical and family history, and inducing or aggravating factors were studied in patients, who participated in the open lectures for childhood AD patients in three provinces of Korea. The severity of the disease was evaluated using the Eczema Area and Severity Index (EASI) and the factors affecting the severity of the disease were determined. Skin prick tests with four allergens, Dermatophagoides pteronyssinus, milk, peanut and egg, were also carried out. RESULTS: Of the 93 patients, 38.7% had the disease onset between the age of three and six, while 17.2% had it between the age of seven and fifteen. Sixty-five percent of the patients had family members with a history of atopic diseases, such as AD, asthma, allergic rhinitis and allergic conjunctivitis. In order of frequency, the patients either had a history of or presently accompanying infantile eczema, allergic rhinitis, asthma or allergic conjunctivitis. Among the patients, 27% took herbal medication. The most frequently involved site was the flexural area. The most common aggravating factors were sweating in hot environment, wool fabric and stress. When AD patients were categorized into mild, moderate and severe groups by EASI, the older onset age, the longer duration, facial distribution, history of taking herbal medication, cholinergic condition, wool fabric and stress were found to be significant factors influencing the severity of the disease. Skin prick test with the four major allergens revealed the highest prevalence in Dermatophagoides pteronyssinus. CONCLUSION: The age of onset of AD was higher than that has been reported. Many suffered from infantile dermatitis and had other accompanying atopic diseases. Aggravating factors should be avoided to minimize the risk of disease aggravation. Based on the fact that late onset age, duration, facial distribution, history of taking herbal medication, cholinergic condition, wool and stress were the statistically significant factors, we may predict the severity or the course of the disease.
