Leptin levels were elevated in thyroid cancer, decreased after total thyroidectomy, and might be associated with thyroid papillary carcinogenesis.

Purpose:To compare the antioxidant enzyme activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and the levels of lipid peroxidation product malondialdehyde (MDA) in blood samples of thyroid cancer patients compared to healthy controls. Methods: 43 control subjects (mean age 44±13 years) and 43 patients (43±13 years) presented with multinodular goiter whose fine needle aspiration revealed malignant cytology were included into this study. The SOD, MDA and GSH-Px activities were measured in control subjects, and before/20 days after thyroidectomy in thyroid cancer patients. Results: SOD activities of pre-thyroidectomy, post-thyroidectomy and control groups were not different (p>0.05). Before thyroidectomy GSH-Px activities were lower (p<0.05) and MDA levels were higher (p<0.05) than the control group. In post-thyroidectomy, GSH-Px activity (p<0.05) increased, and MDA levels (p<0.05) decreased compared to prethyroidectomy levels. After thyroidectomy GSH-Px activity was significantly higher than the control group (p<0.05). Although post-thyroidectomy MDA levels significantly decreased, they were still higher than the control group (p<0.05). Conclusion: The superoxide dismutase does not seem to change with thyroid cancer and thyroidectomy but both antioxidant glutathione peroxidase and lipid peroxidation product malondialdehyde do. These preliminary findings may point out oxidant/antioxidant imbalance associated with thyroid cancer.

The transabdominal preperitoneal (TAPP) procedure for laparoscopic inguinal hernia mesh repair is being applied with increasing frequency. This technique has an acceptable recurrence rate (0.4-3.9%), but has varying complication rates (1.3-17.4%).1,2 We report the first case of mesh penetration of the colon following laparoscopic TAPP repair, treated with colonoscopy.

In conclusion, all of AOPP, FOX, and MDA levels that are markers of protein oxidation and lipid hyperoxidation may induce thyroid cancer development and begin to decrease after thyroidectomy.

PurposeThis study aimed to examine extended postoperative ileus and its risk factors in patients who have undergone abdominal surgery, and discuss the techniques of prevention and management thereof the light of related risk factors connected with our study.MethodsThis prospective study involved 103 patients who had undergone abdominal surgery. The effects of age, gender, diagnosis, surgical operation conducted, excessive small intestine manipulation, opioid analgesic usage time, and systemic inflammation on the time required for the restoration of intestinal motility were investigated. The parameters were investigated prospectively.ResultsRegarding the factors that affected the restoration of gastrointestinal motility, resection operation type, longer operation period, longer opioid analgesics use period, longer nasogastric catheter use period, and the presence of systemic inflammation were shown to retard bowel motility for 3 days or more.ConclusionOur study confirmed that unnecessary analgesics use in patients with pain tolerance with non-steroid anti-inflammatory drugs, excessive small bowel manipulation, prolonged nasogastric catheter use have a direct negative effect on gastrointestinal motility. Considering that an exact treatment for postoperative ileus has not yet been established, and in light of the risk factors mentioned above, we regard that prevention of postoperative ileus is the most effective way of coping with intestinal dysmotility.
