Given an abstract of a paper, generate a title for this paper such that conveys the key focus of the paper.

Example Input: Abstract: Presented is the ninth reported case of teratocarcinoma arising from the parenchyma of the lung. Treatment should include wide surgical resection and adjuvant chemotherapy. Postoperative radiation therapy should be utilized if there is residual disease or nodal metastasis. Preoperative radiation therapy should be considered if there is evidence of chest wall involvement.
Example Output: Primary teratocarcinoma of the lung.

Example Input: Abstract: Early mobilisation after arthroplasty of the knee sometimes results in wound breakdown. The two commonly used incisions, the anterior midline and the medial parapatellar incisions, were compared in order to determine which had the best potential for wound healing. Study of the cleavage lines around the knee demonstrated that the medial parapatellar incision lies parallel to the lines, whilst the anterior midline incision lies perpendicular to them. In addition, the medial parapatellar wound was found to be subjected to significantly less tension during flexion; after arthroplasty it can be expected to heal faster and to be less liable to disruption during early mobilisation.
Example Output: Anterior midline or medial parapatellar incision for arthroplasty of the knee. A comparative study.

Example Input: Abstract: Glyphosate, a widely utilized herbicide, was evaluated for acute irritation, cumulative irritation, photoirritation and allergic and photoallergic contact potential in 346 volunteers. The herbicide was less irritant than a standard liquid dishwashing detergent and a general all purpose cleaner. There was no evidence for the induction of photoirritation, allergic or photoallergic contact dermatitis. 10% glyphosate in water is proposed as a diagnostic patch test concentration.
Example Output:
Irritation, sensitization, photoirritation and photosensitization assays with a glyphosate herbicide.
