Objective: To evaluate the effect of coronal alignment on: (1) surgical invasiveness and operative complexity and (2) postoperative complications. Methods: A retrospective, cohort study of adult spinal deformity patients was conducted. Alignment groups were: (1) neutral alignment (NA): coronal vertical axis (CVA)≤3 cm and sagittal vertical axis (SVA)≤5 cm; (2) coronal malalignment (CM) only: CVA>3 cm; (3) Sagittal malalignment (SM) only: SVA>5 cm; and (4) coronal and sagittal malalignment (CCSM): CVA>3 cm and SVA>5 cm. Results: Of 243 patients, alignment groups were: NA 115 (47.3%), CM 48 (19.8%), SM 38 (15.6%), and CCSM 42 (17.3%). Total instrumented levels (TILs) were highest in CM (14.5±3.7) and CCSM groups (14±4.0) (p<0.001). More 3-column osteotomies (3COs) were performed in SM (21.1%) and CCSM (28.9%) groups than CM (10.4%) (p=0.003). CM patients had more levels instrumented (p=0.029), posterior column osteotomies (PCOs) (p<0.001), and TLIFs (p=0.002) than SM patients. CCSM patients had more TLIFs (p=0.012) and higher estimated blood loss (EBL) (p=0.003) than SM patients. CVA displayed a stronger relationship with TIL (p=0.002), EBL (p<0.001), and operative time (p<0.001) than SVA, which had only one significant association with EBL (p=0.010). Both SM/CCSM patients had higher readmissions (p=0.003) and reoperations (p<0.001) than CM patients. Conclusion: Amount of preoperative CM was a better predictor of surgical invasiveness than the amount of SM, despite 3COs more commonly performed in SM patients. CM patients had more instrumented levels, PCOs, and TLIFs than SM patients.

Objective This investigation examined data on unplanned pregnancies following hysteroscopic sterilization (HS). Methods A confidential questionnaire was used to collect data from women with medically confirmed pregnancy (n=103) registered after undergoing HS. Results Mean (±SD) patient age and body mass index (BMI) were 29.5±4.6 years and 27.7±6.1 kg/m2, respectively. Peak pregnancy incidence was reported at 10 months after HS, although <3% of unplanned pregnancies occurred within the first three months following HS. Mean (±SD) interval between HS and pregnancy was 19.6±14.9 (range, 2 to 84) months. Patients age ≥30 years and BMI <25 reported conception after HS somewhat sooner than younger patients, although the differences in time to pregnancy were not significant (P=0.24 and 0.09, respectively). The recommended post-HS hysterosalpingogram (to confirm proper placement and bilateral tubal occlusion) was obtained by 66% (68/103) of respondents. Conclusion This report is the first to provide patient-derived data on contraceptive failures after HS. While adherence to backup contraception 3 months after HS can be poor, many unintended pregnancies with HS occur long after the interval when alternate contraceptive is required. Many patients who obtain HS appear to ignore the manufacturer’s guidance regarding the post-procedure hysterosalpingogram to confirm proper device placement, although limited insurance coverage likely contributes to this problem. The greatest number of unplanned pregnancies occurred 10 months after HS, but some unplanned pregnancies were reported up to 7 years later. Age, BMI, or surgical history are unlikely to predict contraceptive failure with HS. Further follow-up studies are planned to capture additional data on this issue.

ObjectiveAlthough previous research has suggested that risk for reoperation among hysteroscopic sterilization (HS) patients is more than ten times higher than for patients undergoing standard laparoscopic tubal ligation, little has been reported about these subsequent procedures. MethodsThis descriptive cohort study used a confidential online questionnaire to gather data from women (n=3,803) who volunteered information on HS followed by device removal surgery performed due to new symptoms developing after Essure placement. ResultsIn this sample, mean age was 35.6 years and women undergoing hysterectomy after HS comprised 64.9% (n=2,468). Median interval between HS and hysterectomy was 3.7 (interquartile range, 3.9) years and mean age at hysterectomy was 36.3 years. Some patients (n=1,035) sought removal of HS devices and fallopian tubes only, while other miscellaneous gynecological procedures were also occasionally performed for Essure-associated symptoms. When data from all patients who had any post-Essure surgery besides hysterectomy were aggregated (e.g., device removal + “other” cases, n=1,335) and compared to those cases undergoing hysterectomy, mean age was significantly lower than for the hysterectomy group (34.4 vs. 36.3 years, respectively; P<0.01); uterus-conserving surgeries were also typically performed significantly earlier than hysterectomy (P<0.01). ConclusionThis investigation is the first to characterize specific gynecological operations after Essure, and suggests that the predominant surgical answer to HS complaints is hysterectomy for many women. Dissatisfaction with HS may represent an important indication for hysterectomy and additional study is needed to quantify this phenomenon.

Surface measurements of the 5 June 2013 damaging thunderstorm wind event near Pep, Texas

High-resolution wind measurements at 2.25 m in height were used to investigate the mean and turbulence properties of an extreme thunderstorm wind event in West Texas. These data were combined with single Doppler scans from the Texas Tech University Ka-band mobile Doppler radars systems (TTUKa) to provide meteorological context over the surface measurement stations for portions of the outflow. Several features characteristic of a severe wind event were noted in the radar data, including a bowing portion of the thunderstorm complex and a small circulation on the leading edge. These features were reflected in the surface wind time histories and provided natural separation between various regions of the outflow. These features also contributed to the peak 1-s gust at all measurement stations. The turbulence characteristics of each outflow region were also investigated and compared. Reduced values of running turbulence intensity and elevated values of longitudinal integral scales were noted during the period of peak wind speed. Larger scales of turbulence within the outflow were also suggested via spectral analysis.
