Hyperthyroidism has been associated with liver function abnormalities; however, cholestasis as the presenting feature of adolescent Graves' disease has not been previously reported. ⋯ Severe cholestasis is a rare presenting feature of Graves' disease. With careful monitoring, methimazole can be used to treat the hyperthyroidism in the setting of cholestasis.

Ultrasound (US) of the central neck compartment (CNC) is considered of limited sensitivity for nodal spread in papillary thyroid cancer (PTC); elective neck dissection is commonly advocated even in the absence of sonographic abnormalities. We hypothesized that US is an accurate predictor for long-term disease-free survival, regardless of the use of elective central neck dissection in patients with PTC. ⋯ US of the central compartment is an age-independent predictor for survival and CNC recurrence-free survival in PTC. Prophylactic neck dissection of the central compartment does not improve long-term disease control, regardless of the histopathological status of the lymph nodes retrieved. Our findings emphasize the ability of US to clinically detect relevant nodal disease and support conservative management of the CNC in the absence of abnormal findings.

The association of subclinical hypothyroidism (SCH) with increased risk for cardiovascular disease is still controversial. This study aimed to examine coronary vascular reactivity by positron emission tomography (PET) in asymptomatic patients with SCH before and after levothyroxine (LT4) supplementation. ⋯ In asymptomatic subjects with SCH due to thyroid autoimmunity, coronary microvascular function is impaired and improves after supplementation with LT4. This may partially explain the increased cardiovascular risk attributed to SCH.

A combination of bilateral superficial cervical plexus block (BSCPB) and general anesthesia is recommended for thyroid surgery. Proof of the efficacy of this combination remains weak. Furthermore, data on the safety of this regimen are lacking. Therefore, a meta-analysis of randomized controlled trials (RCT) to evaluate the efficacy and safety of BSCPB as an adjunct to general anesthesia in patients receiving thyroid surgery was performed. ⋯ The combination of BSCPB and general anesthesia has a significant benefit in reducing pain 6 and 24 hours after thyroid surgery. However, the effect on pain reduction is too small to be of clinical relevance. Although it is a safe procedure, the existing evidence allows for no recommendation concerning the application of BSCPB in thyroid surgery. Further trials should evaluate a dose-response relationship and the incidence of PONV with this regimen.
