Effect of heterotopic ossification on cervical motion following Prestige artificial cervical disc replacement / 解剖学报

[Abstract] Objective To analyze the effect of heterotopic ossification(HO) on the postoperative segmental range of motion(ROM)after Prestige artificial cendcal disc replacement, and to explore the related factors leading to the formation of heterotopic ossification after artificial cendcal disc replacement. Methods We recruited of 66 patients who had Prestige artificial cendcal disc replacement from January 2014 to January 2018 in Department of Orthopedics, the First Affiliated Hospital of Chongqing Medical University were retrospectively reviewed. To evaluate cendcal spine X-ray, the replacement segment ROM was measured in picture, and the occurrence of HO was defined by the McAfee' s classification. The Wilcoxon signed rank test was used to analyze the relationship between heterotopic ossification formation and replacement segment ROM,the t test was used to analyze the influence between heterotopic ossification grading and replacement segment ROM. Nine clinical factors including age, gender, bod)' mass index(BMI), number of replacement segments, preoperative ligament ossification, the preoperative disc height ratio of the target level and its adjacent level, preoperative mobility of replacement segments, postoperative mobility of replacement segments, whether to use nonsteroidal autiinflammatory drugs (NSAIDs) during perioperative period. The correlation between these nine clinical factors and the occurrence of postoperative HO was evaluated with logistic regression analysis. Results The occurrence rate of HO was 34. 8% in last follow-up. The replacement segmental ROM of the heterotopic ossification group was significantly smaller than that of the non-ectopic ossification group, and the difference was statistically significant (P<0. 05),and the McAfee grade IH-IV group was significantly less than the McAfee grade I-H group, and the difference was statistically significant (P < 0. 05). Correlation analysis showed that preoperative and postoperative ROM of the replacement segment presented statistical correlation (P < 0. 05). Furthennore analysis of ROC curve showed that heterotopic ossification was more likely to occur when the degree of ROM of the replacement segment

Clinical profile and factors associated with Non-Alcoholic Fatty Liver Disease (NAFLD) among overweight and obese children: A prospective study

@#<p style="text-align: justify;"><strong>INTRODUCTION:</strong> In the past decades, the prevalence of childhood overweight and obesity has increased worldwide. Childhood obesity has been associated with wide range of serious health complications and increased risk of premature adult illnesses. Non-alcoholic Fatty Liver Disease (NAFLD) was of concern because of limited data among children. The study aims to determine the prevalence and demographic /clinical factors associated with NAFLD among overweight and obese children.</p><p style="text-align: justify;"><strong>METHODOLOGY:</strong> The study was a cross-sectional study among overweight and obese participants aged 2-18 years old. A total of 96 subjects were included. Frequencies and percentages of clinical characteristics were determined. Chi-square, linear correlation and logistic regression analysis for different factors were performed.</p><p style="text-align: justify;"><strong>RESULTS:</strong> Among the 92 subjects, 26 (28%) were overweight while 66 (72%) were obese. The M:F ratio was 1.8:1 and majority belonged to 6-10 years old (44%). As to socioeconomic class, the rity (59%) were from the low-income group. The overall prevalence of NAFLD among overweight and obese subjects was 29.3%. None of the clinical factors (age, gender, socioeconomic status, BMI, waist circumference, actual caloric intake, and dietary fat consumption) were significantly associated with NAFLD. Analysis of biochemical factors revealed that alanine aminotransferase, aspartate aminotransferase, serum triglycerides and total cholesterol were found to be associated with NAFLD. Among which AST and ALT were identified predictors of NAFLD.</p><p style="text-align: justify;"><strong>CONCLUSION:</strong> There was high prevalence of NAFLD among overweight and obese children. Screening among the pediatric population may aid on early identification and prevent its progression. ALT, AST, serum triglycerides and total cholesterol were independently related wih NAFLD. AST and ALT were identified predictors of NAFLD.</p>

Clinical Factors Correlated to Delirium Tremens during Acute Alcohol Withdrawal of Inpatients with Alcohol Dependence / 신경정신의학

OBJECTIVES: The aim of this study was to explore clinical factors or high-risk factors associated with occurrence of delirium tremens (DT) during acute alcohol withdrawal in inpatients with alcohol dependence. METHODS: This study included 164 inpatients seeking treatment for acute alcohol withdrawal in the detoxification unit. All subjects were evaluated prospectively for known risk factors for DT and their occurrence of DT. Correlations were determined between risk factors obtained at admission and development of DT. RESULTS: Among all subjects, 42 patients (25.6%) suffered from delirium tremens within seven days after admission. DT patients had more severe alcohol withdrawal symptoms, the presence of past DT, and higher levels of aspartate aminotransferas, alanine aminotransferase, gamma-glutamyl-transpeptidase, and homocysteine, compared with patients who did not suffer DTs. According to results of a multiple regression, occurrence of DT showed correlation with the following factors at admission: tremor, a past history of DT, higher homocysteine level, and nausea and vomiting. CONCLUSION: Development of DT showed correlation with symptoms of severe alcohol withdrawal, past history of DT, and higher homocysteine level. Among these, a severity of alcohol withdrawal symptoms and a history of DT are factors that can be easily evaluated on the day of admission in order to predict the potential for occurrence of DT.

A Comparison of Clinical Characteristics between Medically-treated Patients and Surgically-treated Patients with Ischemic Colitis

BACKGROUND/AIMS: Ischemic colitis (IC) is usually a self-limiting disease. But, it can cause necrosis that requires urgent surgical treatment. We sought to evaluate clinical difference in IC patients between medical and surgical treatment groups, and to identify prognostic factors for adverse outcomes. METHODS: We conducted a retrospective analysis of clinical characteristics in patients with IC treated in Chonnam National University Hospital between May 2001 and April 2010. A total of 81 patients with IC were enrolled. We classified the patients into two groups-a medical treatment group and a surgical treatment group-and evaluated their clinical features, treatment outcomes and mortality. RESULTS: Absence of hematochezia, vomiting, abdominal tenderness, abdominal rebound tenderness, heart rate over 90 beats/min, systolic blood pressure less than 100 mm Hg, hyponatremia and increased LDH or serum creatinine level were observed more frequently in surgically-treated patients (p<0.05). Most cases in the medically-treated group resolved without complications (98.3%). But, about half of the cases (52.4%) of the surgically-treated group resolved and the mortality rate was 47.6%. CONCLUSIONS: In patients with ischemic colitis, several clinical factors are associated with surgical treatment. Although IC is often selflimited, our data suggests that special attention and aggressive therapy is warranted in treating these patients.
