Abstract PDF: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a severe autoimmune paraneoplastic syndrome associated with ovarian teratomas. Most patients develop neurologic symptoms, including psychosis, memory deficits, seizures, or abnormal movements, and experience abdominal pain related to ovarian neoplasm. We present a case report of three patients diagnosed with anti-NMDAR encephalitis accompanied by ovarian teratomas at Ajou University Hospital in Korea. The patients demonstrated a different clinical course of the disease. However, upon diagnosis, all patients underwent surgical removal of the ovarian teratoma followed by intensive immunotherapy. The symptoms progressively improved following treatment. This is a case report of a rare autoimmune anti-NMDAR encephalitis associated with ovarian neoplasms, including immature teratoma.

Gastric mucosal damage by bile acid.: Hyun Hong Cho, Jeong Ill Suh, Keyong Hee Lee, Tae Nyeun Kim, Moon Kwan Chung, Hyun Woo Lee, Won Hee Choi, Chang Heon Yang; Yeungnam Univ J Med. 1992;9(2):342-350. Published online December 31, 1992; DOI: https://doi.org/10.12701/yujm.1992.9.2.342

Abstract PDF: To investigate the effect of bile acid on gastric mucosa, we performed biologic test using Sprague-Dawley rat. Mixture solution of TDCA 15mM and Hcl of pH 3 was given into stomach to one group and HCl of pH 3 was given into stomach to another group. The significant gastric mucosal change was vasodilation and edema, that was disappeared progressively. These findings suggest the bile acid and damage gastric mucosa.
