“The essential elements to pleading a claim for medical malpractice under California law are: 1. The duty of the professional to use such skill, prudence, and diligence as other members of his profession commonly possess and exercise; 2. A breach of that duty; 3. A proximate causal connection between the negligent conduct and the resulting injury; and 4. Actual loss or damage resulting from the professional’s negligence.”
