Background To compare the short-term outcome of patients undergoing single-port laparoscopic salpingectomy (SP-LS) and conventional three-port laparoscopic salpingectomy (C-LS). Methods A retrospective evaluation of 112 patients with tubal pregnancies treated by one surgeon at a single teaching hospital. Among these, 47 patients were treated with SP-LS and the remaining 65 were treated with C-LS. Results The characteristics of patients were similar in both groups. There were no statistically significant differences in operative time, estimated blood loss, intraoperative and immediate postoperative complications, and length of hospital stay between both groups. Time to bowel recanalization (6.2 ± 1.0 vs. 7.2 ± 1.4 h, p < 0.05) and postoperative visual analog scale for pain scores (3.0 ± 0.5 vs. 3.6 ± 0.6, p < 0.005) were significantly lower in the SP-LS group compared with those in the C-LS group. Conclusion Our study demonstrated the feasibility to use the single-port laparoscopic salpingectomy in the management of women with tubal pregnancy, which showed the similar or better outcome compared with the use of conventional three-port laparoscopic salpingectomy.

The emerging resistance to quinine jeopardizes the efficacy of a drug that has been used in the treatment of malaria for several centuries. To identify factors contributing to differential quinine responses in the human malaria parasite Plasmodium falciparum, we have conducted comparative quantitative trait locus analyses on the susceptibility to quinine and also its stereoisomer quinidine, and on the initial and steady-state intracellular drug accumulation levels in the F1 progeny of a genetic cross. These data, together with genetic screens of field isolates and laboratory strains associated differential quinine and quinidine responses with mutated pfcrt, a segment on chromosome 13, and a novel candidate gene, termed MAL7P1.19 (encoding a HECT ubiquitin ligase). Despite a strong likelihood of association, episomal transfections demonstrated a role for the HECT ubiquitin-protein ligase in quinine and quinidine sensitivity in only a subset of genetic backgrounds, and here the changes in IC50 values were moderate (approximately 2-fold). These data show that quinine responsiveness is a complex genetic trait with multiple alleles playing a role and that more experiments are needed to unravel the role of the contributing factors.

Background: Pelvic masses are a common gynecologic problem, and majority of them are diagnosed as ovarian tumors finally. Sometimes, it is hard to distinguish the origin of these pelvic masses. The following case is a solitary neurofibroma arising from the right-side obturator nerve, which was impressed as a right-side ovarian tumor initially. We reported this case, and also performed a PRISMA-driven systematic review to summary the similar cases in the literature. This review includes image, molecular and pathological findings and outcome of neurofibroma. Case presentation: A 33-year-old woman with a regular menstrual period denied any symptoms or signs. During her physical check-up, image examination revealed a right-side heterogeneous pelvic mass; it was suggestive of a complex of right-side ovarian tumor. A provisional diagnosis of retroperitoneal pelvic mass, probably a benign ovarian tumor, was made. Excision of the right-side pelvic mass was performed. We sent the specimens for frozen pathology, which indicated neurofibroma and lipomatous tumor and that the possibility of liposarcoma cannot be excluded. A segment of the obturator nerve was attached to the tumor and was severed. A right-side obturator nerve tear during tumor excision was observed, and a neurosurgeon was consulted for obturator nerve grafting and repair. The patient complained of mild weakness and paresthesia affecting the right leg, and we consulted a rehabilitation doctor for neuron injury. The patient’s recovery was uneventful, and she was discharged eight days after the drain was removed. Further rehabilitation treatment was arranged. Conclusion: A neurofibroma is an uncommon pelvic retroperitoneal tumor, and it can be misdiagnosed as an adnexal mass. To our knowledge, this is a rare case of a solitary neurofibroma arising from the obturator nerve. It usually does not have any neurological deficit. We present this case to demonstrate that pelvic neurofibroma can be mistaken for an adnexal mass. This fact should be borne in mind during the diagnosis process. [ABSTRACT FROM AUTHOR]
