Not sure if this is the cause of your error, but in your insert statement, CASE is a MySQL reserved word and should be escaped with backticks.

$STH = $DBH->prepare("INSERT INTO users (name, 
                                        surname, 
                                        address, 
                                        birth_place,
                                        province,
                                        dt,
                                        sex,
                                        `case`) value (:name
                                                    :surname,
                                                    :address,
                                                    :birth_place,
                                                    :province,
                                                    :dt,
                                                    :sex,
                                                    :case)");
