Objective: To compare the effects of two different intraoperative CO2 pressures (8 and 15 mmHg) during laparoscopic hysterectomy for benign uterine pathologies in terms of postoperative abdominal and shoulder pain, laparoscopy-mediated vegetative alterations, pain medication requirement, arterial CO2 pressure (pCO2 ), surgical parameters, and safety.Design: Prospective randomised controlled study.Setting: German university hospital.Population: Female patients undergoing laparoscopic hysterectomy for benign uterine pathologies.Methods: Patients were randomised to a standard pressure (SP; 15 mmHg, control) or low-pressure (LP; 8 mmHg, experimental) group.Main Outcome Measures: Primary outcomes were postoperative abdominal and shoulder pain intensities, measured via numeric rating scale (NRS) and vegetative parameters (fatigue, nausea, vomiting, bloating) at 3, 24, and 48 hours postoperatively. Secondary outcomes were pain medication requirement (mg) and arterial pCO2 (mmHg). Surgical parameters and intra- and postoperative complications were also recorded.Results: In total, 178 patients were included. Patients in the LP group (n = 91) showed significantly lower postoperative abdominal and shoulder pain scores, fewer vegetative alterations, lower pain medication requirements, a shorter postoperative hospitalization, and lower intra- and postoperative arterial pCO2 values compared with the SP group (n = 87; P ≤ 0.01). No differences in intra- and postoperative complications were observed between groups.Conclusions: Low-pressure laparoscopy seems to be an effective and safe technique for the reduction of postoperative pain and laparoscopy-induced metabolic and vegetative alterations following laparoscopic hysterectomy for benign indications.Tweetable Abstract: Low-pressure laparoscopy seems to be an effective and safe technique for reduction of pain following laparoscopic hysterectomy.

Objective: The objective of this study is to examine the association of lateral fetal neck cysts with increased nuchal translucency, chromosomal abnormalities and fetal malformations. Method: In a consecutive collective of 4216 prenatal ultrasound examinations between 11 and 17 weeks of gestation 32 fetuses with lateral neck cysts were found. The size of the cysts was examined. The association of the findings with increased nuchal translucency, chromosomal aberrations and fetal malformations was examined. Results: All but two out of 32 cases had bilateral cysts. Seventeen fetuses had aneuploidy and an increased nuchal translucency, 15 of those with major structural malformations. Of the 15 fetuses with normal karyotype nine (60%) had an increased nuchal translucency, seven had a fetal malformation or hydrops. A favorable outcome was found in 6/15 fetuses with normal karyotype and normal nuchal translucency. Lateral neck cyst diameter was associated to nuchal translucency, chromosomal abnormality and/or fetal malformations. Cysts smaller than 3 mm had a favorable outcome even in the presence of an increased nuchal translucency. Conclusion: Fetuses with lateral neck cysts often not only present with increased nuchal translucency and chromosomal aberrations but also with fetal malformations. Fetuses with lateral neck cysts and increased nuchal translucency were aneuploid or had a fetal malformation in 85%. Cysts smaller than 3 mm had a favorable outcome. © 2016 John Wiley & Sons, Ltd.

BACKGROUND High-risk human papillomavirus (HPV) infection has been identified as a relevant risk for the development of head and neck squamous cell carcinomas (HNSCCs). As HPV status has also gained a role as a prognostic and predictive biomarker for this entity, there is a growing demand for valid HPV testing in HNSCC patients METHODS Liquid-based cytological smears from 45 HNSCC and 20 control patients were collected and used for simultaneous immunocytochemical p16INK4a/Ki67 staining using a CINtec PLUS kit after the presence of tumor cells was verified in a Papanicolaou-stained slide. The same cytological suspension was used for the detection of HPV DNA by specific polymerase chain reaction (PCR). RESULTS Tumor cells were detected in the swab material of 44 HNSCC patients corresponding to a sensitivity of 98% (44 of 45). PCR analysis revealed the presence of HPV DNA in the cytological suspension of 13 patients (13 of 65, 20%) with simultaneous p16INK4a/Ki67 expression by the tumor cells in 11 of these HPV DNA-positive samples (11 of 13, 85%) - a staining pattern that is strongly associated with a carcinogenic HPV infection. CONCLUSIONS A simultaneous immunocytochemical detection of p16INK4a and Ki67 can reliably be performed on liquid-based cytological smears from HNSCC patients using a CINtec PLUS kit. In addition, the same cytological material can be used for the detection of HPV DNA by specific PCR. The combined results of both techniques enable better discrimination between latent and carcinogenic HPV infections as well as HPV-negative cases and thus can provide information on the prognosis of HNSCC patients and facilitate therapeutic decisions.
