Abstract
Background and Aim: Dermatophytes are keratinophilic fungi that cause infection in the skin, hair and nails. Dermatophytic infections are one of the important health problems in the world that related to social and economic life of communities.
Methods: This cross-sectional study was conducted on all suspected patients in the medical mycology laboratory of Afzalipoor Faculty in Kerman from March 2007 to March 2011. For each patient after obtaining the detailed history, direct smear, staining and culture on specific media were performed.
Results: Out of 1800 referred cases, 166 patients were positive for dermatophytosis. The highest prevalence of infection was in the under 10 years old (28.31%), men and women were also involved equally. The most common agents of the cutaneous infection were Trichophyton mentagrophytes (45.78%) and T. verrucosum (18.1%). The most common infections were tinea manuum (35.54%), tinea capitis (16.87), and the least common one was tinea faciei (4.82%).
Conclusion: It is necessary to increase the level of community health in order to prevent this dermatophytosis.

Abstract
Background and Aim: Skin cancer is the most common
malignancy in the world with high morbidity and relatively low mortality. Basal
cell carcinoma (BCC) is the most common type of cancer and its incidence is
increasing. The purpose of this study was to investigate the incidence of skin
cancer in the years 1386 to 1390 is in the Markazi Province, Iran.
Methods: In this study the data of Markazi Province Cancer Registry
were used and incidence rate was calculated per 100,000 person. Age
standardized incidence rates were calculated via direct standardization method
using world standard population. Finally, the data were analyzed using SPSS, Excel,
and WinPepi softwares.
Results: In Markazi Province, 958 patients with skin cancer
were recorded during 1386-90. The age-standardized incidence rates in these
years were 21.54, 12.06, 13.79, 18.29 and 15.79 per 100,000 people
respectively. There was no significant change in the trend of skin cancer incidence
rates.
Conclusion: Skin cancer was higher in men than women, and
most cases occur in the elderly. Development of screening programs is
recommended to detect skin cancer in its early stages in older men, especially
in those who have been exposed to the sun for long times.

Background and Aim: Skin
cancer is the most common cancer in the world, which is associated with
mortality, mortality and health care costs. Planning prevention and control
of this cancer, information about its incidence rates and incidence trends is
necessary. The present study aimed to determine the incidence rates and
trends of skin cancer in Tehran.
Methods: In this
cross-sectional study, necessary data were extracted from the Cancer
Registry, Ministry of Health and Medical Education between 2003 and 2008. Age
- and sex -standardized incidence rates were calculated and the incidence
rate trends were determined.
Results: Between 2003 and
2008, 7429 skin cancer cases were recorded, of which 4807 were men and 2622
were women. Skin cancer incidence had an increasing trend in Tehran and its
incidence rate has increased from 8.99 in women and 11.52 in men in 2003 to
18.03 in women and 28.16 in men in 2008, respectively. In addition, incidence
of skin cancer was increased with aging in both men and women. The incidence
rate was higher in men than women.
Conclusion: Skin cancer
incidence in Tehran is increasing, which could be due to population aging,
environmental risk factors, and changes in life style. More comprehensive
research is suggested to investigate the risk factors for this cancer in
Tehran.

Abstract
David Lawrence Sackett, OC, MD, FRSC, FRCP was an American-Canadian physician, trialist, and teacher. He is best known as one of the pioneers of evidence-based medicine (EBM), which is arguably the most important movement in medicine over the past three decades. He founded the first clinical epidemiology department in McMaster University in Hamilton, Canada in 1967. In addition, he was the head of the Center for the Evidence-Based Medicine in Oxford, UK. He also was the first chair of Cochrane Collaboration and the first founding coeditor of the journal of Evidence-Based Medicine and had many other honors. He published 12 books, 60 chapters in other books, and about 300 articles in scientific and medical journals.
He died on May 13, 2015 at age 80 because of cholangiocarcinoma. While Dr. Sackett will be missed by his friends, colleagues, mentees as well as EBM proponents and followers all over the world, his contributions to EBM in particular, and to medicine in general will never be forgotten.

Abstract
Background and Aim: Skin cancer is the most common cancer in the Iran. The first step in planning for the prevention and treatment of cancers is collecting information about their incidence and trends. The present study aimed to investigate the epidemiology of skin cancer and its trend in southern Iran.
Methods: This retrospective cross-sectional study was conducted by analyzing the existing data obtained from the National Cancer Registry System in Iran. The data included all records of skin cancer cases in southern Iran. Then, the incidence rates were standardized using direct method. The data were demonstrated in frequency tables and Cochrane-Armitage test for linear trend was used for evaluation of the incidence trend.
Results: Skin cancer had a high incidence in the southern provinces of Iran. A total of 6230 cases of skin cancer during 6 years (2003-2008) were recorded in those provinces and the incidence rate of skin cancer was increasing (P=0.001). In all years of the study, skin cancer incidence was higher in males than women. In terms of frequency, Fars, Khuzestan, Bushehr and Hormozgan provinces had the highest age-standardized incidence.
Conclusion: Considering the high incidence of skin cancer and its relationship to sun exposure, educating people on the correct sun protection, educating and empowering physicians and the people about early detection of skin cancers seems to be important in preventing its increasing trend.

Abstract
Background and Aim: Cancer is the second leading cause of death in the world, as well as skin cancer is the most common cancer among human cancers and causes great costs and economic and social harm to society. The increase in skin cancer in our country and also in Ardabil province led us to study the prevalence and epidemiological trend of 10 years of skin cancer in patients referred to the skin clinic in Ardabil 2011-2021.
Methods: In this study, 331 patients had been referred to a dermatology clinic with a diagnosis of skin cancer during 2011 to 2021. The checklists were completed based on the information in their files.
Results: Of all patients, 208 (62.8%) were male, 60.4% from Ardabil, 14.2% were in year 2016 and 46.2% were in the age group of 50-70 years. The mean age of patients was 62.5±14.7 in range 25-96 years. The most common type of skin cancer in the studied samples during ten years was related to BCC with 184 cases (55.6%) and the most studied patients were in grade 3 with 231 patients (69.8%). The most common site of skin cancer with 93 cases (28.1%) was in the nose.
Conclusion: Results showed that the trend of skin cancer in the studied samples similar to the provincial statistics did not have a constant decrease or increase trend and had a fluctuating trend. The incidence of this disease in male clients was about twice that of female clients and most cases were in high grades and BCC type.
