Business cases are arguments developed to secure management commitment and approval for investment in an intervention. This systematic review evaluated 12 experimental and quasi-experimental studies on occupational health and safety interventions (OHSI) in various settings. The search engines used in this systematic review include PubMed, CINAHL, and Scopus. A cost and benefit analysis of OHSI was completed at the organizational level in these studies. The focus of this analysis included sample, design, theoretical framework, interventional strategies, and threats to validity and outcomes. Positive returns on investment of OHSI outcomes were shown in 10 of the studies. The other two studies concluded that their chosen OHSI were not cost-effective.

Abstract. Extraosseous osteosarcoma originating from paratesticular soft tissue is an extremely rare type of malignant tumor. With the exception of the present study, only one other case of osteosarcoma originating from paratesticular soft tissue has previously been reported. A 52-year-old man presented with a painless scrotal swelling and palpable mass. The patient underwent left orchiectomy with the diagnosis of testicular tumor. Pathological examination was suggestive of osteosarcoma without any different histological components. The postoperative course of the patient was uneventful, and the patient is currently free of disease.
