Golestan province has a reputation for relatively high incidence rates of gastric cancer in Iran. Along with dietary, lifestyle and environmental influential factors, soil selenium and high levels of pesticide used may exert influence in this region. The present study was designed for modeling the influential predictors on incidence of gastric cancer in Golestan. All registered cases of gastric cancer from March 2009 to March 2010 (49 females and 107 males) were investigated. Data were gathered by both check list and researcher made questionnaire (demographic, clinical and lifestyle characteristics) and analysed using logistic regression. Mean (${\pm}SD$) age at diagnosis was $62.9{\pm}13.8$ years. CIR and ASR of gastric cancer showed 9.16 and 13.9 per 100,000 people, respectively. Based on univariate logistic regression, a history of smoking (OR= 2.076), unwashed hands after defecation (OR= 2.612), history of cancer in relatives (OR= 2.473), history of gastric cancer in first-degree relatives (OR= 2.278), numbers of gastric cancers in first-degree relatives (OR= 2.078), history of X-ray and dye exposure (OR= 2.395), history of CT scan encounter (OR= 2.915), improper food habits (OR= 3.320), specific eating behavior (OR= 0.740), consumption of probable high risk foods (OR= 2.942), charred flesh (OR= 1.945), and animal fat (OR= 2.716) were confirmed as a risk factors. Changes in lifestyle may be expected to increase gastric cancer incidence dramatically in the near future. Therefore, appropriate educational interventions should be designed and implemented by competent authorities.

A statistical analysis was made on 15,971 surgically operated patients at D-Medical Center in the year of 1978 and 1988. 1,416 cancer patients among them were classified by sex, age, and malignant tumor site. The obtained results indicated that trend of male cancer was generally similar to the results of nation wide study. But, specific phenomenon was found in the case of female cancer in Daegu-Kyungbuk area. Among females the frequency rank was uterine cervix (35.77%), breast (17.97%), stomach (11.65%) in 1988. The frequency of uterine cervix was higher than other area. Breast cancer was highly ranked tumor compare with other area, and its age distribution also appeared in much younger decade.

This benign canine histiocytoma was the most common single tumor type, followed lipoma, adenoma, soft tissue sarcoma, mast cell tumor and lymphosarcoma [2]. Canine cutaneous histiocytoma (CCH) most commonly occur as solitary lesions, head and pinnae are prefermential sites, that undergo spontaneous regression. The histologic appearance varies greatly, depending on the age of the lesion and the degree of necrosis and secondary inflammation. The age-specific incidence rate for CCH drops precipitously after 3 years, although histiocytomas occur in dogs of all ages [5]. Their etiology and pathogenesis are unknown. This case reports the gross and histopathological findings of canine cutaneous histiocytoma of observed in a young dog with localized calcification of lingual muscle. (omitted)

Purpose: This study was aimed to examine the prevalence of metabolic syndrome (MetS) and cardiovascular risk factors among workers at small-sized companies having fewer than 50employees in Korea. Methods: A descriptive cross-sectional study was conducted using a secondary data analysis on workers' health examination data. Data from 21,784 employed workers were analyzed, including 16,488 males (mean age 38.7years)and 5,296 females (mean age 40.5 years). Participants were newly enrolled in annual health check-ups at a professional health clinic from 2009 to 2011. Logistic regression analysis was performed to identify age-adjusted gender specific predicting factors of MetS incidence. Results: The prevalence of MetS was 13.4% in male and 7.7% in female workers. Logistic regression analysis showed that, when age was adjusted for, family history of cardiovascular disease (CVD) was a predicting factor in both male and female workers. For male workers, heavy alcohol drinking and non-manual occupation (office workers/drivers) predicted MetS. Conclusion: Health care providers should screen for MetS periodically in small work places especially for those with a family history of CVD. Educational counseling needs to be given to male workers with sedentary occupations with an aim to reduce heavy drinking and encourage lifestyle modification.

Background: Older age is associated with an increase in the incidence of cancer cases. Diagnosis and treatment of cancer in older adults can be stressful because of health decline related to age, comorbidities and inadequate treatment for pain and other symptoms of the disease. This survey is one of the unique studies in Jordan and in the Arab world that aimed at exploring the predictors of older adult individuals awareness towards cancer. Materials and Methods: A stratified random sampling technique was followed to reach a representative sample of 753 participants. The questionnaire of the study consisted of parts regarding demographic variables, awareness about screening tests, and signs and symptoms of cancer. In addition, specific questions related to factors linked to cancer were included. Cross-sectional design was adopted with face-to-face interviews at the interviewees' households. Results: The mean age of the participants was about 63 years; around 44% of them are above the age of 65 years. 'Being convinced that having no health problem makes the individual feel safe and not at risk of getting cancer' was the major reason for not doing a routine health check-up. Conclusions: The low levels of awareness about cancer, as well as the low use of the screening methods were crucial outcomes of this study. Thus, raising the awareness among health care providers and policy makers in the country about older adults' perception of cancer is a high priority.

Objective : This study was performed to elucidate the technical and patient-specific risk factors for postoperative ischemia in patients undergoing temporary arterial occlusion (TAO) during the surgical repair of their aneurysms. Methods : Eighty-nine consecutive patients in whom TAO was performed during surgical repair of an aneurysm were retrospectively analyzed. The demographics of the patients were analyzed with respect to age. Hunt and Hess grade on admission, Fisher grade of hemorrhage, aneurysm characteristics, timing of surgery, duration of temporary occlusion, and number of temporary occlusive episodes. Outcome was analyzed at the 3-month follow-up, along with the occurrence of symptomatic and radiological stroke. Results : In overall, twenty-seven patients (29.3%) had radiologic ischemia attributable to TAO and fifteen patients (16.3%) had symptomatic ischemia attributable to TAO. Older age and poor clinical grade were associated with poor clinical outcome. There was a significantly higher rate of symptomatic ischemia in patients who underwent early surgery (p=0.007). The incidence of ischemia was significantly higher in patients with TAO longer than 10 minutes (p=0.01). In addition, patients who underwent repeated TAO, which allowed reperfusion, had a lower incidence of ischemia than those who underwent single TAO lasting for more than 10 minutes (p=0.011). Conclusion : Duration of occlusion is the only variable that needs to be considered when assessing the risk of postoperative ischemic complication in patients who undergo temporary vascular occlusion. Attention must be paid to the patient's age, grade of hemorrhage, and the timing of surgery. In addition, patients undergoing dissection when brief periods of temporary occlusion are performed may benefit more from intermittent reperfusion than continuous clip application. With careful planning, the use of TAO is a safe technique when used for periods of less than 10 minutes.

Purpose: Recently, the incidence of malignant melanoma has been steadily increasing. Malignant melanoma is already known to have poorer prognosis than other primary skin cancers. Despite the poor prognosis, it is relatively less known to the public so that a number of patients visit hospital carrying advanced stage tumor. Yet, extensive study about malignant melanoma is currently insufficient, and specific guidelines and statistical figures in Korea are almost inexistent. Therefore, authors reviewed patients with malignant melanoma who have visited our hospital for last 14 years. Methods: Between January 1994 and January 2008, 62 patients were diagnosed with malignant melanoma at our hospital. A retrospective study was performed with data from patients' charts and biopsy results. Annual incidence, mean age of onset, gender, tumor location, tumor thickness, pathologic ulceration, clinicopathologic subtype, and clinical AJCC stage were evaluated. Analysis of factors associated with survival were performed using the Cox proportional hazard model. Kaplan - Meier method was used to generate survival curves. Results: Clinicopathologic features of 62 patients (32 male, 30 female) with average age of 57 years were evaluated. Most lesions were found in lower limb, and the most common subtype was acral lentiginous melanoma. We could also find that age, tumor thickness, and clinical stage were the only significant prognostic factors. Conclusion: Clinicopathologic features of malignant melanoma were analyzed in this study, but the result is not ready to be generalized because the number of cases is too small. Further study must be performed to report clinical guidelines for prognosis and treatment for malignant melanoma patients in Korea.

Objectives: Bisphosphonates (BP) are widely used in medicine for inhibiting bone resorption; however bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a major side effect of BP. To date, there have been no specific reports on the incidence of BRONJ among Koreans. This study investigated the preliminary results from a nationwide survey of BRONJ in the Departments of Oral and Maxillofacial Surgery (OMFS) at individual training hospitals. Materials and Methods: A total of 15 OMFS departments (10 from dental schools, 4 from medical schools, and 1 from a dental hospital) participated in a multi-centric survey. This study assessed every BRONJ case diagnosed between January 2010 and December 2010. The patient age and BP type were evaluated. Results: A total of 254 BRONJ cases were collected. The majority of BRONJ cases were associated with oral BP therapy, while 21.8% of the cases were associated with intravenous administration. Alendronate was the drug most frequently related to BRONJ (59.2% of cases), followed by risedronate (14.3%) and zolendronate (17.0%). The average age of BRONJ patients was $70.0{\pm}10.1$ years, with a range of 38-88 years of age. With the number of BP patients in Korea reported to be around 600,000 in 2008, the estimated incidence of BRONJ is at least 0.04% or 1 per 2,300 BP patients. Conclusion: The results suggest that the estimated incidence of BRONJ in Korea is higher than the incidence of other countries. Future prospective studies should be carried out to investigate the exact epidemiological characteristics of BRONJ in Korea.

Background: A cancer registry program has been established in East Azerbaijan and this has emphasized the importance of cancers of gastrointestinal tract in this region. The aim of the present pathology-based cancer registry report is to renew epidemiologic aspects of gastrointestinal tract cancers and estimate recent trends. Materials and Methods: A survey team reviewed and collected all records of cancer cases from all referral and valid pathology laboratories of East Azerbaijan province during September 2007-2011. Crude rates, age-specific rates of cancer incidence and annual percent change were calculated. Results: The total newly diagnosed cancer cases (n=6,889)comprised 4,341 males (63.0%) and 2,540 females (36.9%). Gastric cancer was the most common GI tract cancer with an ASR (per $10^5$) of 23.1 for males and 7.69 for females. The ASRs for esophageal and colorectal cancers were 9.69 and 11.2 in males and 7.35 and 8.93 in females. Trend analysis showed a significant decline for esophageal cancer and increasing incidence for colorectal cancer in females. Conclusions: The prevalence of gastric cancer is high in East Azerbaijan province of Iran. This pathology based cancer registry showed an ascending trend for colorectal cancer and decreasing trend for esophageal cancer in females during 2007-2011.
