You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Disease", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Naloxone", ...], "Disease" : ["Hypotensive", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Cerebral sinus thrombosis as a potential hazard of antifibrinolytic treatment in menorrhagia. We describe a 42-year-old woman who developed superior sagittal and left transverse sinus thrombosis associated with prolonged epsilon-aminocaproic acid therapy for menorrhagia. This antifibrinolytic agent has been used in women with menorrhagia to promote clotting and reduce blood loss. Although increased risk of thromboembolic disease has been reported during treatment with epsilon-aminocaproic acid, cerebral sinus thrombosis has not been previously described. Careful use of epsilon-aminocaproic acid therapy is recommended.
