The value of plasma SCUBE1 and oxidative stress parameters in the early diagnosis of acute ovarian torsion.

AIM: The purpose of our study was to determine the diagnostic value of plasma SCUBE1, malondialdehyde (MDA), superoxide dismutase (SOD) and total antioxidant status (TAS) investigated on the 4th hour of ovarian torsion, and at the same time to determine the relation between these markers and histopathological damage occurring in the ovary. MATERIALS AND METHODS: Sixteen rats were included, eight in the torsion group and eight in the control group. The right ovaries of the rats in the torsion group were rotated clockwise 720 degrees, after which they were fixed and attached to the abdominal wall. The abdominal walls of the control group rats were opened for 1 min and then closed. Relaparotomy was performed 4 h after surgery in both groups, blood specimens were collected for biochemical analyses, and the right ovaries were surgically extracted. RESULTS: No statistically significant difference was determined in the control and torsion groups' plasma SCUBE1, SOD and TAS values (p = 0.987, p = 0.33, and p = 0.244, respectively). Torsion group plasma MDA values were significantly higher than those of the control group (p = 0.039). At histopathological evaluation, histological score, apoptotic index and Caspase-3 index values of the torsion group were significantly higher compared to the control group. CONCLUSION: Plasma SCUBE1 is not useful in the early diagnosis of ovarian torsion. Similarly, use of the oxidative stress markers SOD and TAS does not appear useful in early diagnosis, although MDA may be considered for that purpose (Tab. 2, Fig. 3, Ref. 23).

Surgical management of anorectal foreign bodies.

PURPOSE: Anorectal foreign bodies (AFBs) inserted into anus constitute one of the most important problems needing surgical emergency due to its complications. We describe our experience in the diagnosis and treatment of AFBs retained in the rectosigmoid colon. MATERIALS AND METHODS: Between the years 2006 and 2015, a total of 11 patients diagnosed with AFBs were admitted to an emergency room and general surgery clinics. They were diagnosed and treated in four different hospitals in four different cities in Turkey. Information on the AFBs, clinical presentation, treatment strategies, and outcomes were documented. We retrospectively reviewed the medical records of these unusual patients. RESULTS: Eleven patients were involved in this study. All patients were male with their mean age was 49.81 (range, 23-71) years. The time of the presentation to the removal of the foreign bodies ranged between 2 h and 96 h with a mean of 19.72 h. Ten patients inserted AFBs in the anus with the purpose of eroticism but one patient's reason to relieve constipation. The objects were one body spray can, two bottles, three dildos, two sticks, one water hose, one corncob, and one pointed squash. Three objects were removed transanally after anal dilatation under general anesthesia. Eight of the patients required laparotomy (milking, primary suture, and colostomy). Five of the patients had perforation of the rectosigmoid colon. Abdominal abscess complicated extraction in one patient after the postoperative period. The hospitalization time of the patients was 6.18 (1-16) days. None of the patients died. CONCLUSIONS: A careful assessment is a key point for the correct diagnosis and treatment of AFBs. Clinical conditions of patients and type of AFBs are important in the choice of treatment strategy. If the AFBs are large, proximally migrated or the patients with an AFB have acute abdomen due to perforation, pelvic abscess, obstruction, or bleeding, surgery is needed as soon as possible. There are different types of surgical approaches such as less invasive transanal extraction under anesthesia and more invasive abdominal routes such as laparotomy or laparoscopy. The stoma can be done if there is colonic perforation. In the management of AFBs, the priority must be less invasive methods as possible.

The effect of silymarin on mesenteric ischemia-reperfusion injury.

OBJECTIVE: To examine the effect of silymarin (SM), a mixture of flavonoids and polyphenols extracted from Silybum marianum, on mesenteric ischemia-reperfusion (I-R) injury in a rat model. MATERIALS AND METHODS: Fifty rats were randomly divided into 5 groups (n = 10). Group 1 was sham operated, while groups 2-5 were subjected to mesenteric I-R lasting 1 h. Group 2 received isotonic sodium chloride, group 3 received SM (100 mg/kg/day) for 7 days before I-R, group 4 received SM for 7 days after I-R, and group 5 received SM for 7 days both before and after I-R. The rats were sacrificed by exsanguination in groups 1-3 at the 24th hour and groups 4 and 5 were sacrificed on the 7th day of reperfusion. Blood and intestinal specimens were taken for biochemical and pathological evaluations. RESULTS: Serum superoxide dismutase (SOD) and heat shock protein 70 levels were significantly higher in group 2 (5.24 ± 1.76 U/l and 261.4 ± 16.8 ng/ml) compared to the sham group (2.08 ± 1.76 U/l and 189.9 ± 28.7 ng/ml) (p < 0.001 and p < 0.0001, respectively). However, SOD activity and the extent and severity of the histopathological lesions were significantly less in groups 3 [3.11 ± 1.18 U/l, 1.0 (range 0.0-2.0)], 4 [2.15 ± 0.87 U/l, 1.0 (range 1.0-3.0)], and 5 [1.80 ± 0.61 U/l, 0.5 (range 0.0-2.0)], treated with SM, than in group 2 [5.24 ± 1.76 U/l, 2.0 (range 2.0-3.0)] (p = 0.002, p < 0.001, and p = 0.0001; p < 0.001, p = 0.007, and p = 0.0001, respectively). Also, TNF-α levels were lower in the SM-supplemented groups compared to group 2. Serum thiobarbituric acid-reactive substance concentrations were low in the pre-/posttreatment groups treated with SM compared to group 2. No statistical difference was observed for protein carbonyls between the groups. CONCLUSION: Our findings suggest that SM therapy may attenuate the oxidative and intestinal damage induced by I-R injuries.
