firebug output:

syntaxerror: json.parse: unexpected non-whitespace character after json data @ line 1 column 25230 of json data 

and jsonlint.com output json response:

parse error on line 75: ...        "keyword": "ear nose , throat ----------------------^ expecting 'string', 'number', 'null', 'true', 'false', '{', '[' 

you don't need use $.parsejson(); since datatype : 'json' specified. returned data in json format use directly.
