Intrapartum transabdominal ultrasound assessment of the fetal head position during the second stage of labor improves the accuracy of vacuum cup placement during vacuum extraction for prolonged second stage.

Ectopic livers are rarely seen intra-abdominal lesions. Ectopic hepatocellular carcinoma (HCC) can be defined as an HCC arising from hepatic parenchyma located in an extrahepatic organ or tissue. The authors report a case of a primary, well-differentiated HCC arising from ectopic liver tissue in the left subphrenic space at the upper portion of the gastrorenal ligament that was successfully treated by laparoscopic resection. A 59-year-old man was referred to our department for the management of an intra-abdominal mass, which was incidentally found in a follow-up abdominal computed tomography scan for splenic laceration. The preoperative diagnosis suggested that it was a nonspecific stomach mass of maximal diameter 4.5 cm, such as, a gastrointestinal stromal tumor, located between the diaphragm and spleen. A computed tomography scan identified no mass in the liver. Laparoscopic resection was performed, and the final pathologic result confirmed that it was a HCC. The patient's postoperative course was unremarkable. This is the first reported case of a laparoscopically treated ectopic HCC. Moreover, laparoscopic resection was found to be safe and reliable in this case.

ObjectivesUp to 77% of patients with obstructive sleep apnoea (OSA) have positional OSA (POSA) but traditional positional therapy (PT) methods have failed as they were poorly tolerated. New convenient vibratory PT devices have been invented but while recent studies suggest high treatment efficacy and adherence, there are no published data comparing these devices directly with continuous positive airway pressure (CPAP). Our objective is to evaluate if a convenient vibratory PT device is non-inferior to CPAP in POSA treatment.MethodsIn this crossover randomised controlled trial, we enrolled patients with POSA with significant daytime sleepiness (Epworth Sleepiness Scale (ESS)≥10). POSA diagnosis was based on: (1) total Apnoea/Hypopnoea Index (AHI)>10/hour and non-supine AHI<10/hour (2) supine AHI≥2 × non-supine AHI. Patients used their initial allocated devices (PT or CPAP) for 8 weeks before crossing to the alternative intervention after a 1 week washout. The primary aim is to measure changes in ESS between the two treatments. Secondary outcomes include sleep study parameters and patient treatment preference (ClinicalTrials.gov: NCT03125512).Results40 patients completed the trial between April 2017 and December 2018. Difference in ESS after 8 weeks of device use (PT minus CPAP) was 2.0 (95% CI 0.68 to 3.32), exceeding our predetermined non-inferiority margin of 1.5. AHI on CPAP was lower than with PT (4.0±3.2 vs 13.0±13.8 events/hour, respectively, p=0.001), although both were lower than at baseline. Time spent supine was significantly lower with PT than CPAP (p<0.001). 60% of patients preferred CPAP, 20% preferred PT, while 20% preferred neither device.ConclusionsThe non-inferiority ESS endpoint for PT compared with CPAP was not met and the results were inconclusive. Future trials with larger sample sizes or in less symptomatic patients are warranted to provide further insight into the role of these new vibratory PT devices.

Purpose: Borrmann type IV gastric cancer is often diagnosed only at an advanced stage, resulting in a prognosis poor. W e performed a retrospective study of the clinical characteristics of Borrmann type IV gastric cancer and the prognostic factors affecting the survival rate in such patients.Materials and Methods: Of 4,063 patients with all gastric cancers, 370 (9% ) with Borrmann type IV gastric cancer were analyzed.Results: The clinical characteristics of these patients included a higher incidence rate in young females, and higher rates of serosa exposure, metastasis to lymph nodes and early peritoneal dissemination. Of patients presenting with peritoneal seeding, those resected had a higher survival rate than those that were not. A univariate analysis showed that the prognostic factors affecting the survival rate following a curative resection were the location, occupied area and depth of the primary tumor, as well as the presence of lymph node metastasis and the tumor stage. A multivariate analysis indicated that the tumor location and stage were significant independent prognostic factors after a curative resection for Borrmann type IV gastric cancer.Conclusion: In conclusion, the early diagnosis and treatment of patients with Borrmann type IV gastric cancer are essential for the better survival of these patients.
