Clinical application of percutaneous transforaminal endoscope-assisted lumbar interbody fusion / 中国骨伤

OBJECTIVE@#To conclude of the technical notes of percutaneous transforaminal endoscope-assisted lumbar interbody fusion (PT-Endo-LIF), and to investigate its safety and efficacy for treatment of degenerative lumbar disease.@*METHODS@#Twenty-four patients were treated by PT-Endo-LIF combined with posterior percutaneous pedicle screws fixation from October 2017 to April 2018. There were 16 males and 8 females, ranging in age from 39 to 72 years old, with a mean of (59.6±9.5) years old. There were 15 cases diagnosed with lumbar intervertebral disc herniation combined with degenerative disc, the other 9 cases were diagnosed as low level lumbar spondylolistheses w/o segmental instability. Single segmental fusion was performed for 22 cases(one for L₂,₃, 3 for L₃,₄ and 18 for L₄,₅) and 2 segmental fusion was performed for the other 2 cases (both for L₃,₄ and L₄,₅). PT-Endo-LIF was performed under local anesthesia with conscious sedation, followed by decompression through endoscopic technics. After that, end-plate preparation and autogenous bone and expandable cage implantation were performed. Finally, percutaneous screws and rod instrumentation were used. The visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the clinical efficacy. The operation time, intraoperative bleeding volume, intraoperative and postoperative complications were recorded. All patients underwent X-ray, CT plain scan, three-dimensional reconstruction and MRI examination to evaluate the stability of the implants and fusion rate before 3 days and 1, 3, 6, 12 and 18 months after operation.@*RESULTS@#All patients were followed up, and the duration ranged from 12 to 18 months. The operation time of single-segment fusion was (192.3±22.7) min, and that of double-segment fusion was (272.5±24.7) min. The estimated intraoperative bleeding volume was less than 50 ml per segment, and no blood transfusion was performed in all patients. The VAS improved from preoperative 7.4±1.1 to postoperative 2.3±0.8 (=-19.65, <0.000 5). The ODI improved from preoperative (41.2±3.3)% to the final follow-up (12.3±2.5)%(=-35.76, <0.000 5). Postoperative complications occurred in 4 cases, and contralateral radicular symptoms occurred in 2 cases. After contralateral foraminoscopic decompression, the symptoms were completely alleviated. One case had neurological symptoms related to percutaneous screw placement, and the symptoms were alleviated after removal of the lateral screw rod internal fixation. The other cases had surgical incision infection and improved after debridement and suture. At the latest follow-up, no displacement or loosening of the fusion cage and screw rod system occurred in all patients, and 14 cases showed signs of fusion.@*CONCLUSIONS@#PT-Endo-LIF is a minimal invasive, safe and efficient surgical procedure for treatment of degenerative lumbar disease. Nevertheless, the long-term results still need to be confirmed by a multi-center and lagre sample follow-up study.

Optimal Operational Definition of Patient with Peptic Ulcer Bleeding for Big Data Analysis Using Combination of Clinical Characteristics in a Secondary General Hospital / 대한소화기학회지

BACKGROUND/AIMS: Peptic ulcer bleeding (PUB) is the most common cause of upper gastrointestinal bleeding in Korea but there has been no research done using big data. This study evaluates the optimal operational definition (OD) for big data research by analyzing clinical characteristics of PUB. METHODS: We reviewed the clinical characteristics of 92 patients with PUB confirmed on endoscopy in Wonkwang University Sanbon Hospital (January 2013 to December 2014). We calculated sensitivity and positive predictive value (PPV) to detect confirmed PUB patients using ODs developed by combining clinical features of patients with PUB. RESULTS: The mean patient age was 63 years. Men had higher prevalence of PUB than women. Bleeding gastric ulcer was proportionately common in the age range of 40s to 60s in men, while a significantly higher rate of bleeding occurred in women older than 70s. The rate of drug-induced ulcer was 28.2%, whereas the prevalence of Helicobacter pylori was 47.8%. Among the hospitalized patients with diagnostic code of PUB, we ruled out patients with endoscopic removal of gastric adenoma or peritonitis, and selected patients who had been administered intravenous proton pump inhibitor. The sensitivity in this setting was 82.6%, and PPV was 88.4%. CONCLUSIONS: PUB was more common in older patients, and there was a clear gender difference in gastric ulcer bleeding by age. With a proper OD using PUB diagnostic codes, we can identify true patients with sufficiently high sensitivity and PPV.

Associations Between Daily Food and Nutrient Intake and Bone Mineral Density in Men Aged 50 Years and Older

Osteoporosis is a rising problem, as the older age population is increasing due to prolongation of life. Genetic and environmental factors play key roles in bone metabolism, and diet is also an important factor. We investigated the relationship among factors affecting bone mineral density (BMD), including daily food intake and nutrient intake in men aged >50 years. Seventy-eight men, who visited the health promotion center at one of the university medical centers, were divided into normal and osteopenia groups according to their BMD. The body weight of the normal group was significantly higher than that of the osteopenia group. The osteopenia group showed significantly higher carbohydrate intake and lower calcium and vegetable calcium intake compared to those in the normal group. Lumbar spine BMD was negatively correlated with energy, fat, vitamin B1, and sodium intake in the normal group. Additionally, femoral neck BMD was negatively correlated with total animal protein, energy, protein, fat, phosphorous, iron, animal iron, potassium, vitamin B1, B2, B6, and niacin intake. Lumbar spine BMD was positively correlated with fruit, calcium, vegetable calcium, animal calcium, and vitamin C intake in the osteopenia group. Femoral neck BMD was negatively correlated with meat, dairy product, total animal protein, plant protein, animal protein, vitamin A, and cholesterol intake. A stepwise multiple regression analysis revealed that several dietary factors affected BMD, including energy, fat, vitamin B1, B2, B6, niacin, sodium, protein, iron, animal iron, phosphorous, potassium, and animal protein in the normal group and zinc, calcium, vegetable calcium, animal calcium, vitamin C, fruit, protein, animal protein, meat, dairy product, carbohydrates, cholesterol, vegetables, mushrooms, and seasonings in the osteopenia group. These results indicate that adequate nutrient intake plays an important role maintaining optimum bone health in middle aged men.

Investigation on the real herb of Mugwort leaf and the standard of its processing for moxibustion / 中国针灸

Mugwort leaf is the traditional herb being used for moxibustion. Although its place of production and the course of making Mugwort floss have been described in detail, there is no unified standard about the quality and processing of Mugwort floss until now, which seriously affect on the popularity and application of moxibustion. In accordance with the real herb of Mugwort leaf and floss as well as its processing and quality judgment, this paper thoroughly analyze the related data including ancient documents, modern research results and clinical applications. The authors consider that the Mugwort floss in the market is lack of regulations for its processing, and it needs to be discussed the way to judge the quality of Mugwort leaf by volatile oil, suggesting that the further study on the quality control of Mugwort leaf and floss has to be carried out from multiple aspects, such as physical attributes and chemical characteristics.

Analysis on chemical compositions of Artemisia Argyi from Qichun of different years and moxa wool refined in different proportions / 中国针灸

The article aims at providing theoretical foundation for security of moxibustion through analyzing chemical compositions of Artemisia Argyi of different years from Qichun County, Hubei Province, and moxa wool refined in different proportions. Artemisia Argyi from Qichun on 2007, 2008 and 2009 were taken as raw materials, and processed into moxa wool with the proportions of raw material and product as 3 : 1, 5 : 1, 8 : 1 and 15 : 1, respectively. Essential oils of Artemisia Argyi and the refined moxa wool were extracted by steam distillation. Their chemical compositions were identified by gas chromatography-mass spectrometry (GC-MS) and calculated with semiquantitative method. The result showed that chemical compositions of Artemisia Argyi of different years and moxa wool refined in different proportions were almost the same, but their contents were with obvious difference. The relative content of volatile substances decreased with the age prolonged and a rise in the proportion of the refined moxa wool, while the involatile material increased. Therefore it can be concluded that the essential oil of Artemisia Argyi from Qichun and the refined moxa wool is basically safe. Involatile substances such as Juniper camphor, Caryophyllene oxide and Caryophyllene etc. are the main contents of high proportional moxa wool of old year. And these substances may be the effective components in moxibustion treatment.

Associations of Lifestyle Behaviors, Dietary Habits and Bone Mineral Density in Men Aged 50 Years and Older

Lifestyle behaviors including dietary habits are well known to play key roles in bone metabolism. The purpose of this study was to investigate the relationship among the factors affecting bone mineral density (BMD) including age, anthropometric parameters, lifestyle behaviors, and dietary habits of men aged more than 50 years. Ninety-one men, who visited health promotion center at one of the university medical centers, were divided into two groups according to the BMD: normal and osteopenia. The BMD of femoral neck in the osteopenia group was significantly lower than that of the normal group (0.77 +/- 0.28 vs. 0.98 +/- 0.08 g/cm2). The proportion of the regular exercisers was significantly lower in the osteopenia group than in the normal group (p = 0.027). In the osteopenia group, the femoral neck BMD was significantly decreased in smokers and coffee drinkers compared to no-smokers and no-coffee drinkers. The femoral neck BMD was increased among those who consume breakfast and beans and bean products more frequently and those with a greater meal regularity. In the normal group, the lumbar spine BMD was significantly increased among those with frequent consumption of beans and bean products. The lumbar spine BMD was significantly correlated with exercise (r = 0.263), and the femoral neck BMD with weight (r = 0.284), BMI (r = 0.324), relative body weight (r= 0.294), exercise (r = 0.269) and frequency of beans and bean products consumption (r = 0.216). These results indicate that lifestyle behaviors and dietary habits play important roles in maintaining optimum bone health in the middle-aged men.
