MIT (magnetic induction tomography) image reconstruction from data acquired with a single, small inductive sensor has unique requirements not found in other imaging modalities. During the course of scanning over a target, measured inductive loss decreases rapidly with distance from the target boundary. Since inductive loss exists even at infinite separation due to losses internal to the sensor, all other measurements made in the vicinity of the target require subtraction of the infinite-separation loss.

Article Synopsis
  • - Therapy with thyroid hormones is primarily for treating hypothyroidism, using oral medication most of the time, with intravenous options only for specific cases like gastrointestinal issues or severe medical conditions.
  • - Levothyroxine is the preferred treatment for various conditions, including congenital hypothyroidism and myxoedema coma, where intravenous administration is used until patients can resume oral therapy.
  • - Although intravenous thyroid hormones can improve cardiac function after surgery, studies show no significant impact on overall morbidity or mortality, and oral administration is equally effective in many situations.

At the intersection of injury-prone sports such as baseball and conditions like ADHD that affect all aspects of life, there is a lack of research. This limits the availability of preventive care programs designed to target potential risks and promote a safe experience. In this retrospective cohort study, we assess the frequency of injury in youth baseball players with and without ADHD, along with further investigation into how treatment with stimulant medication may modify risk factors.

Objective: To identify early available predictors for the long-term outcome of patients after transsphenoidal surgery (TSS) in the management of Cushing's disease.

Methods: This single-center, retrospective study included 93 consecutive patients with Cushing's disease (follow-up 12-129 months, mean 48, median 38) who underwent TSS (21 had previous operations elsewhere). Six cases had early re-operation, and the resulting data were evaluated instead of the respective first operation.
