Seat belt-related thyroiditis documented with thyroid Tc-99m pertechnetate scans.

A 64-year-old man presented with clinical unilateral thyroiditis after chronic left neck trauma from his car seat belt. Thyroid function tests were normal. The initial thyroid Tc-99m pertechnetate scan demonstrated decreased uptake in the entire left lobe of the thyroid. The follow-up scan 1 month later showed a more normal uptake in the left lobe. This patient's clinical course, laboratory values, and nuclear medicine scans are compatible with thyroiditis secondary to trauma sustained from his seat belt.

Effect of blinking on tear elimination as evaluated by dacryoscintigraphy.

To document the change in drainage of tears that occurs with blinking, the authors evaluated 17 lacrimal systems of 12 individuals with dacryoscintigraphy. A significant difference in tear drainage was found by keeping the eyelids closed during the first 2 minutes after drop placement (P less than 0.03), but not from 2 to 5 minutes (P greater than 0.4). Retardation of tear drainage after droplet placement can be achieved by simple eyelid closure for 2 minutes.

The scintigraphic "duodenal cut off sign" in acute pancreatitis.

Acute pancreatitis is a dreaded complication of biliary calculus disease, and several radiographic signs have been reported in association with this condition. We report a new sign demonstrated on hepatobiliary scintigraphy, the duodenal cut off sign, seen in a patient being evaluated for stone disease and later found to have acute pancreatitis. Hepatobiliary scans are commonly performed during the initial evaluation of patients with suspected calculus disease, and visualization of this sign may indicate to the clinician that he is dealing with a more serious condition.

Relative canalicular tear flow as assessed by dacryoscintigraphy.

Studies evaluating the relative importance of the upper and lower canaliculi in tear drainage have been many and varied, and at times the application of the data to clinical situations is difficult. In order to evaluate the relative tear flow in the upper and lower canaliculi and to quantitatively evaluate the different tear flow rates by a physiologic method, we have studied 11 patients using partial canalicular obstructions and dacryoscintigraphy. The authors found no statistical difference in tear flow between the upper and lower canalicular systems. This information has clinical application when deciding whether to repair an isolated canalicular injury.
