Review Case Reports
Efficacy of bosentan in patients with refractory thromboangiitis obliterans (Buerger disease): A case series and review of the literature.
The cornerstone of therapy in thromboangiitis obliterans (TAO) is complete abstinence from tobacco. In addition to discontinuation of cigarette smoking, very few pharmacological and surgical options of controversial efficacy are available to date. New therapeutic options with greater efficacy are clearly needed to properly manage these patients. ⋯ When comparing patients who gave up smoking with those who were unable to completely abstain from smoking during follow-up, no significant differences were found in efficacy outcomes. Four patients (15%) developed adverse events, requiring bosentan discontinuation in 1 case. These preliminary data suggest that bosentan may be considered a therapeutic option for treatment of cases of severe TAO refractory to conventional treatment, and merit further evaluation in larger controlled, randomized clinical studies.

Recent studies have paid much attention on the safety of bevacizumab as adjuvant chemotherapy for metastatic colorectal cancer. The aim of this meta-analysis was to study the efficacy and safety of bevacizumab in combination with irinotecan, bolus followed by infusional 5-fluorouracil, and leucovorin (FOLFIRI) and, irinotecan, bolus fluorouracil, leucovorin (IFL) for patients with metastatic colorectal cancer (mCRC). An electronic search of related trials was conducted from PubMed, EMBASE, Cochrane Library databases. ⋯ Compared with FOLFIRI and IFL alone, the addition of bevacizumb significantly increased the partial response (PR) and objective response (OR) rates. Compared with IFL alone, the addition of bevacizumb significantly reduced the mortality risk of PFS (RR [95%CI] = 0.53[0.42, 0.66], P < 0.00001) and OS (RR[95%CI] = 0.70[0.60, 0.82], P < 0.00001), but increased the risk of adverse events (RR[95%CI] = 1.14[1.06, 1.21], P = 0.0002). Combination chemotherapy of bevacizumab plus FOLFIRI or IFL had a relative high efficacy and acceptable safety for treatment of mCRC.

Review Case Reports
Prenatal diagnosis and genetic discoveries of an intracranial mixed neuronal-glial tumor: A case report and literature review.
Congenital intracranial tumors as a group are quite rare, representing only 0.5% to 1.5% of all pediatric brain neoplasms. ⋯ Prenatal detection of mixed neuronal-glial tumor is very rare. Ultrasound is of critical importance to detect the intracranial tumors, and MRI can give us some detailed information about the tumors. However, the precise histologic type was depended on the pathological examination. CMA should be necessary for the fetuses with congenital intracranial tumors, especially when the fetal chromosomal karyotype analysis is normal.

Randomized Controlled Trial
Efficacy and safety of continuous radiofrequency thermocoagulation plus pulsed radiofrequency for treatment of V1 trigeminal neuralgia: A prospective cohort study.
Patients may develop serious eye complications after continuous radiofrequency thermocoagulation (CRF) for V1 (ophthalmic division) trigeminal neuralgia (TN) at a higher temperature. Therefore, the temperature of clinical CRF for V1 TN has long been disputed, but there have few reports been found about how to achieve satisfactory pain relief, reduce the incidence rates of complications, and shorten the recovery time after CRF for V1 TN. To observe whether pulsed radiofrequency (PRF) can lead to increased rate in pain relief, reduced rate of complications, or shortened recovery time after CRF is used to treat V1 idiopathic trigeminal neuralgia (ITN). ⋯ The mean scores of HRQoL in group B patients were higher than that in group A patients (P < 0.05). PRF after CRF results in decreased recurrence of V1 TN, reduced numbers of corneal hypoesthesia, shortened recovery time, and increased HRQoL scores. Its clinical use is recommended.

Review Case Reports
Laparoscopic management of a twisted ovarian leiomyoma in a woman with 10 weeks' gestation: Case report and literature review.
Primary leiomyoma of the ovary is a rare benign ovarian tumor that only seldom causes acute abdomen. ⋯ Despite its low incidence, torsion of ovarian leiomyoma should be considered in the differential diagnosis of acute abdomen. Furthermore, laparoscopic exploration should be the preferred way of removing twisted ovarian leiomyoma, even during pregnancy. It seems that primary ovarian leiomyomata have a tendency to grow rapidly during early pregnancy. However, because of the low incidence of ovarian leiomyoma, the effects of estrogen and pregnancy on this condition remain unclear.
