A Rare History: an Intracranial Nail Present for Over a Half-Century.

We present a rare case of a patient with a persistent headache for many years found to have an intracranial nail present for nearly 65 years. The nail was found entering approximately 1 cm from the midline on the left side, passing below the superior sagittal sinus, with the tip 1.5 mm right of the frontal horn of the lateral ventricle. Treatment strategies designed to optimize outcome for intracranial foreign bodies and possible complications are discussed in this report. We also discuss the decision for surgical intervention for foreign bodies and the relevance of position of the foreign body.

Effect of protection of enoxaparin against experimental ischemia/reperfusion injury in the rat ovary on in vitro fertilization outcomes.

OBJECTIVE: The study aimed to investigate the protection of enoxaparin (E) against experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries on in vitro fertilization outcomes. METHODS: In total, 56 adult female Sprague-Dawley albino rats were randomly assigned to 6 groups of 8 animals each: Sham, Ischemia, I/R, Sham+E, I+E, and I/R+E. Ischemia groups were subjected to bilateral adnexal torsion for 3 h. In contrast, I/R and I/R+E groups received subsequent detorsion for 3 h. Enoxaparin (0.5 mg/kg s.c.) was administered 30 min prior to ischemia (I+platelet-rich plasma) or reperfusion (I/R+I+platelet-rich plasma). Ovaries were stimulated through intraperitoneal injection of 150-300 internal units IU/kg pregnant mare serum gonadotropin. Anti-Müllerian hormone levels were measured before and after surgery in all groups. RESULTS: When the number of metaphase II oocytes was evaluated, statistically significant differences were observed between the I and I+E (p=0.001) and I/R and I/R+E (p=0.000) groups. When both I and I+E groups and I/R and I/R+E groups were compared, it was found that E application increased the number of fertilized oocytes. The number of embryos on the second day was higher in the I/R+E group than that in the I/R group. Statistically significant differences were found in the number of grade 1 embryos between the I/R and I/R+E groups (p=0.003). In comparing anti-Müllerian hormone values within the group, the highest decrease was observed in the I and I/R groups. CONCLUSION: Enoxaparin effectively minimizes ovarian damage and preserves ovarian reserve following ovarian torsion.

The protective effect of cilostazol on experimental ischemia/reperfusion injury in rats ovaries on in vitro fertilization outcomes.

Objective: Ovarian torsion decreases ovarian reserve because of ischemic and reperfusion damage it causes. In this study, we investigated the protective effect of cilostazol (CIL) on experimental ischemia (I) and ischemic-reperfusion (I/R) damage in rat ovaries with in vitro fertilization (IVF) results. Materials and Methods: Forty-eight adult female Sprague-Dawley albino rats were randomly assigned to 6 groups with 8 animals in each group: Sham (S), I, I/R, S + CIL, I + CIL and I/R + CIL. The I groups were subjected to bilateral adnexal torsion for 3 h, while the I/R and I/R + CIL groups received subsequent detorsion for 3 h. Twenty-two mg/kg of CIL was given via oral gavage 30 min before surgery on the I (I+ CIL) or reperfusion (I/R + CIL) groups. Oocytes were collected before the IVF procedure and after ovulation induction with 150-300 IU/kg pregnant mare serum gonadotropin. Results: The metaphase oocytes reached their highest value of 4.73±0.96 in the S+ CIL group and reached their lowest value of 0.51±0.55 in the I/R group. There were statistically significant differences in the number of second-day embryos among the I, I+ CIL, and I/R and I/R+ CIL groups (p=0.000). When the groups were compared in terms of Anti-Müllerian hormone change, the highest decrease was observed in the I and I/R groups. Conclusion: CIL pretreatment before surgery has a protective effect against I and I/R in rats with ovarian torsion.
