Detectability and surgical outcomes in parathyroid surgery – a single-centre experience

The incidence of primary hyperparathyroidismand referrals for the removal of parathyroid adenomas are increasing. Factors that improve the detectability, and ultimately the surgical outcome, are the focus of this retrospective study. We included 117 patients who had parathyroid operations with intraoperative monitoring of parathyroid hormone (PTH). Sestamibi, ultrasound and, in selected cases, fusion with computed tomograms (CT), were done to locate the lesion preoperatively. Concentrations of calcium and PTH before and after operation, specimen weight, and preoperative vitamin D concentrations, were assessed. The sensitivity of sestamibi and ultrasound for the preoperative location of adenomas was 92% and 80%, respectively. Sestamibi located them more accurately in patients with low preoperative concentrations of vitamin D (p = 0.037) and with heavier adenomas (p < 0.001). We found no significant association between the preoperative concentrations of PTH and detectability on preoperative scans (p = 0.058). Postoperative follow up showed that 97% of the 117 patients were biochemically cured. Accurate location helps to lower morbidity as it facilitates a targeted approach. Further studies are needed to explore the role of vitamin D in the location of parathyroid adenomas before parathyroidectomy.     

Learning condyle repositioning during orthognathic surgery with a surgical navigation system

Condyle repositioning during bilateral sagittal splint osteotomy (BSSO) is a challenging step for the inexperienced surgeon. We aimed to demonstrate the benefit of navigation for learning the condyle repositioning. We treated 100 patients who underwent a BSSO. A trainee performed the condyle repositioning of one side in two phases. In the first one, the trainee positioned without watching the screen of the Orthopilot Navigation system (ONS). In the second one, the trainee could use the ONS to replace the condyle. Heuristic, anatomical and functional scores of each phase were recorded. Heuristic (17% vs. 75%; p < 0.0001), anatomical (35% vs. 86%; p < 0.0001) and functional (14% vs. 56%; p < 0.0001) scores were significantly greater with the ONS. The ONS is a promising and original intraoperative learning tool for the repositioning of the condyle during BSSO.     

Learners’ acceptance of a webinar for continuing medical education

The aim of this study was to evaluate learners’ acceptance of a webinar for continuing medical education that was instigated by the International Association of Oral and Maxillofacial Surgeons (IAOMS). A live, interactive webinar on orthognathic surgery was broadcast via the Internet. The learners’ acceptance of the webinar was evaluated using a standardized, validated questionnaire (Student Evaluation of Educational Quality, SEEQ). One hundred and fifty-three participants attended the webinar; 55 participants (46 male, nine female) completed the questionnaire. The mean age of the respondents was 41.6 ± 10.0 years. The age of male and female respondents did not differ significantly. The respondents were spread over five continents, with the highest number from Brazil. The SEEQ showed a high level of acceptance for almost all subscales. There was no statistically significant difference between male and female respondents concerning acceptance of the webinar (P = 0.614). The wide distribution of participants shows the potential for webinars as facilitators of barrier-free distribution of knowledge. The webinar was well accepted by the attendees independent of sex, specialty, and work experience. However, the sex ratio reflects the underrepresentation of women in oral and maxillofacial surgery.     

Braden scale for pressure ulcer risk predicts rehabilitation placement after pancreatic resection

BackgroundPatients undergoing pancreatic resection frequently require rehabilitation facilities after hospital discharge. We evaluated the predictive role of validated markers of frailty on rehabilitation facility placement to identify patients who may require this service.MethodsSingle-center retrospective cohort study of patients who underwent pancreatic resection from 2010 to 2015. 90-day morbidity and mortality were calculated. Postoperative validated markers of frailty (Activities of Daily Living scale, Braden scale [assesses pressure ulcer risk, lower scores = higher risk] and Morse fall scale) were evaluated via multivariate regression to identify predictors of discharge to rehabilitation facility.Results470 patients with complete data were included. Mean age was 62 and 49.2% were male. Postoperative median length of stay (LOS) was 8 (IQR 7–10). 92 (19.66%) patients were discharged to rehabilitation facilities and 138 (29.49%) patients were readmitted within 90 days. On multivariate analysis, age, sex, LOS > 8 days, inpatient Comprehensive Complication Index (CCI) and initial Braden scale were predictive of rehabilitation placement.ConclusionA marker of frailty routinely collected daily by nursing staff, the Braden scale, is available to help surgeons predict the need for postoperative rehabilitation placement after pancreatic resection. Engaging discharge planning services for at-risk patients may help prevent delayed hospital discharge and should be further evaluated.     

Fertility Outcome After Renal Transplantation: A Single-Center Experience

BackgroundWomen suffering from kidney disease are more prone to fertility problems, due to uremia. Fortunately, their fertility rate increases dramatically after renal transplantation. This study analyzes the predictors/risk factors of successful pregnancy with live birth outcome while presenting an overview of the 7-year experience of a single center.MethodsThis retrospective cohort study includes 239 women of reproductive age (18–40 years) who underwent renal transplantation in a tertiary Turkish clinic between October 1, 2011, and August 24, 2017. The subjects were invited to take part in a survey questioning their obstetric characteristics and they were assessed in 2 groups: fertile and infertile. Multivariable linear regression analysis was conducted to determine the predictors of a successful pregnancy.ResultsThirty-five 35 patients wished to become pregnant: 12 got pregnant spontaneously, while 21 failed to become pregnant (spontaneously). The mean age of the patients at the survey was 34 ± 7. Regular menstrual cycles after renal transplantation, tacrolimus-mycophenolate mofetil maintenance protocol, and age at transplantation were found to be predictors of spontaneous pregnancy. The duration of peritoneal dialysis was significantly longer in the infertile group (48 vs 12 months).ConclusionEnd-stage renal disease's negative impacts, including menstrual abnormality and fertility problems, can be overcome by successful kidney transplantation with appropriate immunosuppression. Minimizing the duration of peritoneal dialysis, particularly in patients who desire future fertility, may be accepted as a logical management strategy.     

Should we look for Hirschsprung disease in all children with meconium plug syndrome?

BackgroundMeconium plug syndrome (MPS) is associated with Hirschsprung disease (HD) in 13–38% of cases. This study sought to assess institutional variation in utilization of rectal biopsy in children with MPS and the likelihood of diagnosing HD in this population.MethodsPatients with MPS on contrast enema in the first 30 days of life from the Pediatric Health Information System database in 2016–2017 were included. Institutional rates of rectal biopsies performed during the initial admission were calculated and then used to predict institutional rates of early HD diagnoses using Poisson regression.ResultsOf 373 newborns with MPS, 106 (28.4%) underwent early rectal biopsy, of whom 43 (40.5%) had HD. Fifty-seven (15.3%) were ultimately diagnosed with HD. Eight (14%) of these patients had a delayed diagnosis. HD rates between institutions did not differ significantly (range 0–50%, p = 0.52), but usage of early rectal biopsy did (range 0–80%, p = 0.03). Each additional early biopsy increased the early HD diagnosis rate by 35% (β = 0.30, 95% CI 0.15–0.45, p < 0.0001).ConclusionThe incidence of HD is increased in children with MPS. There is significant hospital variability in the utilization of early rectal biopsy, and opportunity exists to standardize practice.Type of Study: Study of Diagnostic testLevel of Evidence: Level III
