First, an upper endoscopic examination was performed, but abnormal findings of the esophagus, including a mucosal break, hiatal hernia, and whitish mucosa, were not detected (Fig. 1). Washout ratio was 40% in the right parotid gland, 25% in the left parotid gland, 25% in the right submandibular gland, and 30% in the left submandibular gland (Fig. 1).
Saliva scintigraphy was performed to evaluate the salivary function before treatment with nizatidine. Washout ratio was decreased in the parotid glands.

After the treatment, salivary scintigraphy was done and demonstrated the increased washout ratios in all four major glands (Fig. 2).
