RESUMEN
BACKGROUND: Persistent/recurrent hyperparathyroidism occurs in 2%-5% of patients with sporadic primary hyperparathyroidism (PHPT). In this study, the incidence and time to recurrence in patients with single-gland disease (SGD), double adenomas (DAs), or four-gland hyperplasia (FGH) at initial parathyroidectomy were compared. METHODS: This retrospective review included adult patients with sporadic PHPT who underwent initial parathyroidectomy with intraoperative parathyroid hormone monitoring (IOPTH) from 1/2000 to 12/2016 with ≥6 mo follow-up. An abnormal parathyroid was defined by a gland weight of ≥50 mg. A concurrent serum calcium >10.2 mg/dL and parathyroid hormone >40 pg/mL was defined as persistent PHPT if present <6 mo and recurrent PHPT if present ≥6 mo postoperatively after initial normocalcemia. RESULTS: Of 1486 patients, 1203 (81%) had SGD, 159 (11%) DA, and 124 (8%) FGH. Among the 3 groups, there was no difference in the percent decrease from the baseline or time of excision to final postexcision IOPTH levels between groups (79% versus 80% versus 80%, respectively; P = 0.954) or in the proportion of patients with a final IOPTH ≥40 (22% versus 18% versus 14%; P = 0.059). Overall, 22 (1.5%) had persistent PHPT and 26 (1.7%) had recurrent PHPT. Persistent PHPT was more frequent with DAs (6; 3.8%) than other groups (SGD: 16, 1.3%; FGH: 0; P = 0.02). At median follow-up of 33 mo (IQR, 18-60), there was no difference in recurrence rate (1.6% versus 2.5% versus 2.4%; P = 0.57) or median time (mo) to recurrence (SGD: 59 [IQR, 21-86], DAs: 36 [IQR, 29-58], FGH: 23 [IQR, 17-40]; P = 0.46). CONCLUSIONS: Recurrent PHPT occurred in 1.7% of patients who underwent curative initial parathyroidectomy, with no difference in incidence or time to recurrence between groups based on the number of glands removed. Patients with DA more commonly had persistent PHPT, raising the possibility of unrecognized FGH.

BACKGROUND: An institutional protocol for selective calcium/calcitriol supplementation after completion/total thyroidectomy was established based on the 4-hour postoperative parathyroid hormone level. The aim of this study was to evaluate the outcomes of this protocol 5 years after implementation. METHODS: All patients who underwent completion/total thyroidectomy from January 2012 to December 2016 were reviewed. Predictors of a 4-hour parathyroid hormone level <10 pg/mL and symptomatic hypocalcemia were assessed. RESULTS: Of 591 patients, 448 (76%) had a 4-hour parathyroid hormone ≥10, 72 (12%) had a 4-hour parathyroid hormone of 5-10, and 71 (12%) had a 4-hour parathyroid hormone <5. Hypocalcemic symptoms were infrequent (30/448, 7%) if the 4-hour parathyroid hormone was ≥10; 56% (40/71) of those with a 4-hour parathyroid hormone <5 reported symptoms. With 4-hour parathyroid hormone of 5-10, symptoms were reported in 32 of 72 (44%) patients; supplementation at discharge included calcium (nâ¯=â¯55, 76%), calcium and calcitriol (nâ¯=â¯12, 17%), or none (nâ¯=â¯5, 7%). Ten patients subsequently received calcitriol for persistent symptoms. On multivariate analysis, predictors of 4-hour parathyroid hormone <10 included incidental parathyroidectomy, malignancy, and thyroiditis; predictors of hypocalcemic symptoms included age <55 and 4-hour parathyroid hormone <10. CONCLUSION: After completion/total thyroidectomy, patients with a 4-hour parathyroid hormone ≥10 can be safely discharged without routine supplementation. The addition of calcitriol to calcium supplementation should be strongly considered for patients with a 4-hour parathyroid hormone of 5-10.

Postoperative hypocalcemia is a common complication of total thyroidectomy resulting from manipulation, resection, or devascularization of the parathyroid glands. Parathyroid hormone (PTH) levels assessed in the perioperative period have been used to predict development of hypocalcemia. Articles examining the role of PTH measurement in the perioperative period following total or completion thyroidectomy are reviewed. Focus is placed on the timing of PTH measurement and the ability to predict which patients will develop hypocalcemia requiring supplementation. Postoperative PTH determination is highly accurate in predicting the development of hypocalcemia. Studies have examined PTH levels drawn at differing time points, ranging from intraoperatively until postoperative day 1 (POD1) with similar accuracy. This data is used to guide postoperative selective calcium and calcitriol supplementation in patients at highest risk for hypocalcemia. When evaluated within the first 4 hours postoperatively, predictive accuracy is maintained but can allow for earlier discharge for those patients at lower risk. Alternatively, some authors argue for routine supplementation, which can reduce the rate of postoperative hypocalcemia but increases the rate of unnecessary supplementation and potential risks associated with hypercalcemia. PTH determination at four hours after total thyroidectomy is an accurate predictor of hypocalcemia and can guide selective calcium supplementation for those at high risk, as well as facilitate a safe earlier hospital discharge for those at low risk of developing postoperative hypocalcemia.

BACKGROUND: Outcomes after traumatic brain injury are worsened by secondary insults; modern intensive-care units address such challenges through use of best-practice pathways. Organisation of intensive-care units has an important role in pathway effectiveness. We aimed to assess the effect of a paediatric neurocritical care programme (PNCP) on outcomes for children with severe traumatic brain injury. METHODS: We undertook a retrospective cohort study of 123 paediatric patients with severe traumatic brain injury (Glasgow coma scale scores ≤8, without gunshot or abusive head trauma, cardiac arrest, or Glasgow coma scale scores of 3 with fixed and dilated pupils) admitted to the paediatric intensive-care unit of the St Louis Children's Hospital (St Louis, MO, USA) between July 15, 1999, and Jan 15, 2012. The primary outcome was rate of categorised hospital discharge disposition before and after implementation of a PNCP on Sept 17, 2005. We developed an ordered probit statistical model to assess adjusted outcome as a function of initial injury severity. We assessed care-team behaviour by comparing timing of invasive neuromonitoring and scored intensity of therapies targeting intracranial hypertension. FINDINGS: Characteristics of treated patients (aged 3-219 months) were much the same between treatment periods. Before PNCP implementation, 33 (52%) of 63 patients had unfavourable disposition at hospital discharge (death or admission to an inpatient facility) and 30 (48%) had a favourable disposition (home with or without treatment); after PNCP implementation, 20 (33%) of 60 patients had unfavourable disposition and 40 (67%) had favourable disposition (p=0·01). Seven (11%) patients died before PNCP implementation compared with two (3%) deaths after implementation. The probit model indicated that outcome improved across the spectrum of Glasgow coma scale scores after resuscitation (p=0·02); this improvement progressed with increasing injury severity. Kaplan-Meier analysis suggested that neuromonitoring was started earlier and maintained longer after implementation of the PNCP (p=0·03). Therapeutic intensity scores were increased for the first 3 days of treatment after PNCP implementation (p=0·0298 for day 1, p=0·0292 for day 2, and p=0·0471 for day 3). The probit model suggested that increasing age (p=0·03), paediatric risk of mortality III scores (p=0·0003), and injury severity scores (p=0·02) were reliably associated with increased probability of unfavourable outcomes whereas white race (p=0·01), use of intracranial pressure monitoring (p=0·001), and increasing Glasgow coma scale scores after resuscitation (p=0·04) were associated with increased probability of favourable outcomes. INTERPRETATION: Outcomes for children with traumatic brain injury can be improved by altering the care system in a way that stably implements a cooperative programme of accepted best practice.

The purpose of this retrospective review was to determine the long-term consequences of retained bullet foreign bodies in children after gunshot injury. All children managed for gunshot wounds at an urban, level I pediatric trauma center were evaluated, identifying those discharged with retained bullet foreign bodies. Overall, 244 children were treated for gunshot wounds, 107 (44%) had retained foreign bodies, 24 (22%) experienced long-term complications related to retained foreign bodies, and 14 (13%) required removal. Complications occur in a significant subset of pediatric patients with retained bullets. Prophylactic bullet removal appears unnecessary, although close outpatient follow-up is warranted.

PURPOSE: Our goal is to identify the impact of time to surgical intervention on the outcomes of infants with gastroschisis. METHODS: After institutional review board approval, we performed a retrospective review of the medical records of all infants admitted to our institution from 2001 to 2010. Transport, bowel stabilization, and closure times were defined as the time from birth to admission, admission to the first-documented operative intervention, and first operative intervention to abdominal closure, respectively. Outcomes included age at full enteral feeds, total parental nutrition days, ventilator days, and hospital length of stay. Multivariate analysis was used to identify independent predictors of the outcomes. RESULTS: One hundred eighteen infants with gastroschisis were included in our study. Transport and bowel stabilization times were not predictive of any outcome. However, the time to abdominal wall closure and postnatal gastrointestinal complications were independently predictive of age at full enteral feeds, total parenteral nutrition days, and hospital length of stay. CONCLUSION: Time to surgical evaluation/bowel stabilization was not predictive of any clinically relevant outcomes in infants with gastroschisis. These data demonstrate that potential benefits from prenatal regionalization of infants with gastroschisis are not supported by decreased time to operative intervention.
