ABSTRACT
Aim: To determine the epidemiological, diagnosis and treatment of secondary bone cancer at the National Hospital University Hubert Koutoukou Maga of Cotonou. Patients and Method: It was a retrospective descriptive cross-sectional study carried out from January 1999 to December 2013 on the records of patients treated in the rheumatology department. The selected files had radiological images of tumor appearance objectified by two radiologists. The diagnosis of secondary bone cancer was confirmed after a bone biopsy or the discovery of a primitive tumor site. Patients with hematologic malignancy and incomplete or insufficiently explored records were excluded. Results: Among 10,292 patients followed in the service, 51 (0.5%) had documented bone metastasis. The sex ratio was 1.83. The mean age of patients was 54 ± 9 [26-85] years, with 53% of those over 60 years old. Secondary cancers were on the spine (74.5%), pelvis (35.3%) and the long bones (39.2%). The primary cancer most frequently found was that of the prostate and breast (45.1% and 27.6%, respectively) followed by genital and digestive cancers (9.8% and 7.8%, respectively). Treatment was dominated by hormone therapy (83%) bisphosphonates (70.5%) and chemotherapy (57%). Conclusion: The profile of bone cancer in Benin hospital is very diverse and dominated by the types and osteolytic ostéocondensant. Primary cancers were dominated by the prostate and breast. Bisphosphonates took an important place in the treatment of the disease.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...
