Cyclophilin A (CyPA) is a 17 kDa, ubiquitously expressed multifunctional protein that possesses peptidylprolyl cis-trans isomerase activity and scaffold function. Its expression is increased in inflammatory conditions including rheumatoid arthritis, autoimmune disease and cancer. Intracellular CyPA regulates protein trafficking, signal transduction, transcription regulation and the activity of certain other proteins. Secreted CyPA activates cardiovascular cells resulting in a variety of cardiovascular diseases; including vascular remodeling, abdominal aortic aneurysms formation, atherosclerosis, cardiac hypertrophy and myocardial ischemic reperfusion injury.

The association of ovarian teratoma and anti-N-Methyl-Daspartate receptor (anti-NMDAR) is one of the most common autoimmune encephalitis syndromes and it is a serious and potentially fatal pathology that occurs in young women. This case report describes of a pediatric patient with anti-NMDAR encephalitis. A-12-year-old girl presented with abnormal behavior for one week came to Emergency Department of Sarawak General Hospital, Malaysia. She had psychotic spectrum symptoms including suicidal tendency. She was diagnosed with anti-NMDAR encephalitis as positive antibody was seen in her cerebrospinal fluid. She was treated with Injection Immunoglobulin. She turned out to have teratoma which was successfully removed later. Her progress was remarkable after the surgery with the Immunoglobulin. A multi-disciplinary team involving a psychiatrist, neurologist and gynaecologist liaised with intensivist to successfully manage the case and achieve the good outcome.

Uterine artery pseudoaneurysm (UAP) is a rare acquired vascular malformation associated with vaginal bleeding or intraabdominal haemorrhage occurring after pelvic surgery. Pseudoaneurysm may present with delayed, severe haemorrhage after a seemingly uncomplicated initial postoperative period. Treatment is therefore necessary to prevent further complications. We describe here a case of a 32-year-old mother, who presented with abdominal pain and intraabdominal bleeding, 20 days after Caesarean Section. Computerised Tomography (CT) scan showed the presence of haemoperitoneum, suggestive of pseudoaneurysm at the right cervical artery which was successfully managed with emergency angiographic embolisation.
