Introduction: Unintended perioperative dural tear is a common complication in spine surgery. Methods: Retrospective analysis of patients over 60 years of age who underwent surgery for degenerative disease of the lumbar spine at the Department of Neurosurgery (University Hospital in Martin) from January 2016 to December 2017. Incidence of incidental perioperative durotomy was analyzed. We analyzed selected risk factors − gender, ASA (American Society of Anesthesiologists), surgical diagnosis, type of surgical performance, range of surgical procedure, revision surgery and comorbidities. The results were statistically evaluated using descriptive statistics and Fisher›s test. Results with p<0.05 were considered statistically significant. Results: Our group consisted of 166 patients, 70 men and 96 women (42.2%/57.8%). Perioperative dural tear occurred in 23 patients (13.8%). Increased incidence of dural tear was at level L4/L5 (56.5%). Results showed a statistically significant increased incidence of iatrogenic durotomy in women compared to men (7.1%/18.7%; p=0.0404). Spondylolisthesis was considered as a statistically significant risk factor of an incidental dural tear (p=0.0125). We found a statistically significant relationship between the presence of type II diabetes mellitus (p=0.0397), osteoporosis (p=0.0166) and the presence of peroperative incidental durotomy. Conclusion: Our retrospective study showed a statistically significant increased incidence of incidental peroperative durotomy in females compared to males, in patients with spondylolisthesis, in patients with type II. diabetes mellitus and osteoporosis. Dural tear occurred most commonly at the level of L4 / L5.

Background/Aims. Patients with type II diabetes mellitus (DM) were known to have higher prevalence of gastroesophageal reflux disease (GERD) in the Western countries, but data on the impact of GERD on DM patients in our country are scarce. The aim of this study was to evaluate the prevalence of GERD in type II DM patients in Shanghai, China, and to explore its possible risk factors.Methods. 775 type II DM cases were randomly collected. Reflux Disease Questionnaire (RDQ) was used to check the presence of GERD. Patients’ characteristics, laboratory data, face-to-face interview, nerve conduction study, and needle electromyogram (EMG) test were analyzed.Results. 16% patients were found with typical GERD symptoms. Pathophysiological factors such as peripheral neuropathy, metabolism syndrome, and obesity were found to have no significant differences between GERD and non-GERD type II DM patients in the present study.Conclusion. The prevalence of GERD in type II DM patients is higher than that in adult inhabitants in Shanghai, China. No difference in pathophysiological factors, such as peripheral neuropathy, and metabolism syndrome was found in DM-GERD patients, suggesting that further study and efforts are needed to explore deeper the potential risk factors for the high prevalence rate of GERD in DM patients.

ABSTRACTMetabolic syndrome (SM) is a compound of risk factors of cordiovascular disease occurancy. Obesity and type IIdiabetes mellitus are the main two of the risk factors. The epidemiological data shous that the prevalence ofmetabolic syndrome in the world is 20-25%. The objective of these research is control to minimize the prognosisof the disease among the SM population that have obesity and type II DM risk factors. The pontryagin minimumprinciple is used to determine the optimal solution of the prognosis model that the optimal control. The solution is derived from the state and co-state state equations that are evaluated of the drug that give to the sufferer in stationary conditions. The performance Index was designed to minimize the number of SM population that suffer obesity and type II diabetes mellitus and the use of sulfonilurea that given as the normoweighted populations and biguanid for obese populations. The simulation of the optional solution shows that the optimal control was derived to control the number SM that have population of the optional solution obesity and type II DM risk with optimal biguanide 500 mg and sulfonilurea 5 mg as much.Keywords : Metabolic Syndrome, Minimum Pontryagin, Obesity, Stability ,Type II Diabetes Mellitus.

A study was carried out, in order to assess the risk factors associated with type-II diabetes mellitus in males (Age≥40 years) in district Mardan. Four hundred cases and controls (Each 200) were selected from 10 union councils (7 rural and 3 urban) by a systematic sampling method. In order to select cases and controls, all were interviewed for medical history, on fulfillment of which, cases and controls were separately included for study. In anthropometry, weight, and height were taken for Body Mass Index while waist and hip circumference were taken for waist-to-hip ratio. Fasting blood sugar of cases and controls was determined with the glucometer. Cases and controls were interviewed with Food frequency questionnaire and other questionnaires in order to assess the demographic and socioeconomic characters of the families. The results disclosed that most of the cases had family history of diabetes. In addition to that, cases were also found to have higher (p<0.05) average weight, height and body mass index, and fasting blood sugar level to those of controls. These results also revealed that there was a distinguished (p<0.05) association between dairy and fruit with the health status and about 1/3rd of both cases and controls had satisfactory consumption of dairy and fruit only. A significant link was found among family size, exercise, type of exercise, duration of exercise, watching television, duration of watching television and the status of disease. The study revealed that a combination of anthropometric, dietary and demographic variables were associated with type-II diabetes mellitus in male adult population of district Mardan.
