Surgical Management of Adnexal Masses in Pregnancy

Background and Objectives: Our objective was to review the surgical management, surgical outcomes, and obstetric outcomes of adnexal masses in pregnancy. Methods: A retrospective review was performed of pregnant women before 20 weeks of gestation who underwent laparoscopy or laparotomy for management of an adnexal mass during the period of January 2005 to June 2012 at a university-affiliated hospital. Results: Thirty-five pregnant women underwent surgical removal of adnexal masses during the 7.5-year study period: 21 (60.0%) underwent laparoscopic surgery, and 14 (40.0%) underwent laparotomy. The left upper quadrant entry technique was used in 20 women. Conversion to laparotomy was required in 2 women because of extensive pelvic adhesions. The mean gestational age at surgery was 15.2 ± 1.9 weeks. All women had undergone ovarian cystectomy. A malignant mass was found in 3 (8.6%) women. The laparoscopy group had a significantly less blood loss (67.4 ± 55.8 vs 153.6 ± 181.0 mL, P = .048) and shorter mean hospital stay (2.8 ± 1.0 vs 3.8 ± 1.1 days, P = .006) than the laparotomy group. One woman miscarried soon after surgery. There was no significant difference in obstetric outcomes between the laparoscopy and laparotomy groups. Conclusion: Surgical management of adnexal masses during pregnancy appears to have favorable outcomes for the mother and the fetus.published_or_final_versio

Recording of natural head position using stereophotogrammetry: A new technique and reliability study

The purpose of this study was to develop a technique to record physical references and orient digital mesh models to natural head position (NHP) using stereo-photogrammetry (SP). The first step was to record the digital mesh model of a hanging reference board placed at the capturing position of the SP machine. The board was aligned to the true vertical using a plumb bob. It was also aligned with laser plane parallel to the hanging mirror which was located at the center of the machine. Parameter derived from the digital mesh model of the board was then used to adjust the roll, pitch and yaw of the subsequent captures of subjects. This information was valid until the next machine calibration. The board placement was repeatable with standard deviation of less than 0.1 degrees for both pitch and yaw; 0.15 degrees for roll angles.postprin

Evolving management for critical pulmonary stenosis in neonates and young infants

Over the years, management of critical pulmonary stenosis in young infants has evolved from surgical reconstruction of the right ventricular outflow tract and closed pulmonary valvotomy to transcatheter balloon valvoplasty. Our study aimed at evaluating how the changing policy for management had affected the immediate and long term outcomes of babies with this cardiac lesion. Interventions were made in 34 infants at a median age of 8.5 days (2-90 days). Reconstruction of the right ventricular outflow tract reconstruction was performed in 10 patients, closed pulmonary valvotomy in 13, and balloon valvoplasty in 11. Initial procedure-related mortality was 50%, 15% and 0% respectively. Multivariate analysis revealed transannular patching of the right ventricular outflow tract, and male sex, to be significant factors for death. For the 27 survivors, the ratio of right ventricular to systemic systolic pressure decreased from 1.6 ± 0.3 to 0.3 ± 0.2 after reconstruction of the outflow tract, 1.8 ± 0.5 to 0.8 ± 0.4 after closed valvotomy, and 1.8 ± 0.6 to 0.9 ± 0.3 after balloon valvoplasty. The decrease was significantly greater after patch reconstruction (p=0.025) that required no further reinterventions. The overall rate of reintervention for the survivors was 37% (10/27). The freedom from reintervention after closed valvotomy was 82%, 64% and 51% at 1, 5 and 10 years respectively. The figure remained at 78% at both 1 and 5 years (p=0.66) after balloon valvoplasty. The higher reintervention rate for closed valvotomy corresponded to the significantly greater residual gradient across the pulmonary valve noted on follow-up (p=0.01). Reinterventions included balloon dilation (n=6), reconstruction of the outflow tract (n=4), and 1 each of ligation of an arterial duct and systemic-pulmonary arterial shunting. The risk factor for reintervention was a hypoplastic right ventricle. In conclusion, transcatheter balloon valvoplasty appears to be the optimum initial approach in view of its low mortality, efficacy at relieving the obstruction, and low rate of reintervention. © Greenwich Medical Media Ltd.published_or_final_versio

Second trimester termination of pregnancy after previous classical caesarean section for uterine fibroid

E-poster - EP13: Early Pregnancy: no. EP13.05This journal suppl. entitled: Special Issue: Abstracts of the RCOG World Congress 2013, 24–26 June 2013, Liverpool, United KingdomOBJECTIVES: To report the successful termination of pregnancy in a patient with history of previous classical caesarean section performed because of uterine fibroid obstructing the lower segment. METHODS: The patient had classical caesarean section performed for transverse lie, uterine fibroid 14 months prior to presentation requesting termination of pregnancy at 14 weeks maturity. During the operation, a 16 cm broad ligament fibroid was found posteriorly in the left side. The patient was treated with the following regimen 1. Insertion of hygroscopic cervical dilator the night before 2. Misoprostol 50 microgram vaginally, then 100 microgram vaginally 4 hours after initial dose, then 150 microgram vaginally 8 hours after initial dose, then 200 microgram ...published_or_final_versio

Molecular Identification of Spirometra erinaceieuropaei Tapeworm in Cases of Human Sparganosis, Hong Kong

Human sparganosis is a foodborne zoonosis endemic in Asia. We report a series of 9 histologically confirmed human sparganosis cases in Hong Kong, China. All parasites were retrospectively identified as Spirometra erinaceieuropaei. Skin and soft tissue swelling was the most common symptom, followed by central nervous system lesions.published_or_final_versio

Design and performance of the first IceAct demonstrator at the South Pole

In this paper we describe the first results of IceAct, a compact imaging air-Cherenkov telescope operating in coincidence with the IceCube Neutrino Observatory (IceCube) at the geographic South Pole. An array of IceAct telescopes (referred to as the IceAct project) is under consideration as part of the IceCube-Gen2 extension to IceCube. Surface detectors in general will be a powerful tool in IceCube-Gen2 for distinguishing astrophysical neutrinos from the dominant backgrounds of cosmic-ray induced atmospheric muons and neutrinos: the IceTop array is already in place as part of IceCube, but has a high energy threshold. Although the duty cycle will be lower for the IceAct telescopes than the present IceTop tanks, the IceAct telescopes may prove to be more effective at lowering the detection threshold for air showers. Additionally, small imaging air-Cherenkov telescopes in combination with IceTop, the deep IceCube detector or other future detector systems might improve measurements of the composition of the cosmic ray energy spectrum. In this paper we present measurements of a first 7-pixel imaging air Cherenkov telescope demonstrator, proving the capability of this technology to measure air showers at the South Pole in coincidence with IceTop and the deep IceCube detector
