Reflectance Pulse Oximetry: The use of backscattered light rather than transmitted light can be helpful in low-signal settings.
Improved Signal Processing for Pulse Oximetry: Proprietary algorithms and advances in signal processing have improved the precision of pulse oximetry.
Calorimetric Detection: Colorimetric CO₂ detection can be used to ensure nasoenteric placement rather than respiratory placement.

Parathyroidectomy is indicated for symptomatic primary hyperparathyroidism or asymptomatic primary hyperparathyroidism when medical surveillance is not possible or desired.
Preoperative imaging is necessary for preoperative planning if minimally invasive parathyroidectomy is planned. Imaging may include sestamibi scan, ultrasonography, and four-dimensional CT.
Total parathyroidectomy with autotransplant or 3.5-gland parathyroidectomy is recommended in the setting of familial primary hyperparathyroidism such as multiple endocrine neoplasia.

Oncogenic signatures responsible for the transformation MPNST include activation of the STAT3/HIF, catenin/Wnt and RHO/ROCK pathways.
MPNSTs often harbor recurrent inactivation of polycomb repressive complex 2 from somatic mutation of EED and/or SUZ12.
Genetic analysis revealed germline mutations in SMARCB1 in approximately 50% of individuals affected by familial schwannomatosis.
Germline mutations in LZTR1 were identified in about 80% of schwannomatosis cases lacking mutations in SMARCB1.

Tertiary hyperparathyroidism is the persistence of hyperparathyroidism initially secondary to renal failure after a patient has had renal transplantation.
Parathyroidectomy is recommended to obtain normal serum calcium in tertiary hyperparathyroidism.
Tertiary hyperparathyroidism may present with a single adenoma, multiple adenomas, or four-gland hyperplasia. Limited resection of affected glands in case of single or double adenomas may be appropriate, although higher recurrence rates are reported.
