Primary osseous sarcomas of the mobile spine are rare bony tumors. Ewing sarcoma, chondrosarcoma, chordoma and osteosarcoma constitute the majority of primary bone sarcomas of the spine; however, other rare sarcoma tumors may also affect the spine. In order to perform an epidemiological study of theses tumors, national registries may help to evaluate data for populations with similar characteristics. ⋯ Ewing sarcoma was the most frequent primary osseous sarcoma of the mobile spine. A male predilection was observed among all major sarcomas of the mobile spine. Ewing sarcoma in Iran affects the mobile spine in slightly older ages compared to other studies. Myxoid chondrosarcoma is the most frequent subtype of the mobile spine chondrosarcoma. Chordoma affects male in older ages compared to females. In contrast with other studies which showed a bimodal distribution of osteosarcoma of the spine including young adult and older age groups, 86% of cases in Iran were in the age group of 10-40 years.

This study was designed and conducted to investigate the spatial distribution of permanent and temporary congenital hyperthyroidism (PCH and TCH) in Isfahan. ⋯ Adding the time dimension and performing spatial-temporal analysis is suggested because of the following items: high prevalence of CH in Isfahan province, the important role of this disease in mental retardation and neuropsychiatric disorder, the necessity of conducting future medical researches to find possible factors of CH etiology in Isfahan province, as well as necessity of performing spatial analysis with advanced statistical methods.

Given the overwhelming mental health consequences of infectious epidemics, timely identification and treatment of people with mental health problems is essential. In this narrative review, screening instruments and procedures for identification of mental health problems at the time of epidemic crises are reviewed and the results are discussed in the context of our experience in the recent COVID-19 epidemic in Iran. ⋯ The evidence base for screening at the time of epidemics is weak. If it is used to identify the needs and enhance help seeking, the screening instruments should have adequate psychometric properties; moreover, their integration in the available services is strongly recommended. Original studies are needed to investigate the usefulness of mental health screening programs in crises such as the COVID-19 epidemic.
