Background: Epithelial ovarian cancer is increasingly often diagnosed in young females who wish to preserve their fertility. Fertilitypreserving surgeries, where conservation of the uterus and contralateral ovary was performed, might be beneficial for patients with stage I epithelial ovarian cancer, but their safety is still controversial. In the present study, we aimed to compare radical surgery and fertility-saving surgery in females with stage IA–C epithelial ovarian cancer for recurrence and survival rates, as well as to evaluate reproductive and obstetric outcomes for stage I epithelial ovarian cancer females who were managed with fertility-saving surgery. Materials and methods: We prospectively identified 60 patients aged ≤40 years who were diagnosed with stage I epithelial ovarian cancer. The patients in the fertility-preservation group underwent salpingo-oophorectomy on the side of the affected ovary in addition to incisional biopsy or wedge excision of the ovary on the other side. The patients in the radical surgery group underwent total hysterectomy and bilateral salpingo-oophorectomy. We followed up all patients for 5 years to assess their reproductive and oncological outcomes. Results: Patients in the fertility preservation surgery group were significantly younger (30 ± 4 versus 35 ± 5 years) (p < 0.001), their tumor sizes were smaller (3.4 ± 1.3 versus 6.0 ± 2.6 cm) (p < 0.001), of lower grade (p = 0.011), earlier stage (p < 0.001) and had more mucinous histology than patients in the radical surgery group. There were no statistically significant differences between both groups regarding tumor recurrence or survival rates. Of 25 patients who underwent fertility preservation surgery, 18 (72%) attempted to conceive. A total of 15/18 (83%) pregnancies were recorded, including 13 live births, 1 miscarriage, and 1 intrauterine fetal death. Conclusion: Fertility-sparing surgery could be an adequate alternative to radical surgery for young females with stage I epithelial ovarian cancer.

A regular static interior solution of Einstein’s field equations representing a perfect fluid cylinder of finite radius is presented. The solution is matched to the Levi-Civita vacuum solution at a boundary where the pressure vanishes. The density and pressure are finite and positive inside the cylinder for a specific range of the mass parameter. The solution could thus represent a reasonable source for the Levi-Civita metric.

Cylindrically symmetric perfect fluid solutions are derived for the Levi-Civita metric. The pressure P is finite. The matter density is greater than the stresses in the material. The solutions are inside cylinders of bounded radius at which the pressure vanishes. The range of σ, for which the sources have been matched to the Levi-Civeta metric is ∞>σ>0. The solutions are regular and satisfy energy conditions

Background Small bowel arteriovenous malformations (AVMs) are the most common cause of obscure gastrointestinal bleeding, and they are problematic cases both in diagnosis and treatment. Patients and methods A total of 12 patients with small bowel AVMs admitted to Zagazig University hospitals were included in this study. Cases with previous bleeding (group I) and cases with moderate ongoing bleeding (group II) underwent both capsule endoscopy (CE) and intraoperative enteroscopy (IOE), whereas cases with massive ongoing bleeding (group III) underwent IOE only. Results CE picked up the diagnosis of AVMs only in 50% of cases. It underestimated the extent of the lesions in 40% of positive cases and wrongly localized the lesion in 20% of positive cases. IOE diagnosed all 12 cases of AVMs. Two cases were treated with plasma photocoagulation and 10 cases were treated with resection of the diseased segment. There was only one perioperative mortality. Conclusion CE has a limited diagnostic yield in cases of small bowel AVMs especially in absence of ongoing bleeding, and IOE remains the mainstay method for diagnosis and treatment of these cases.
