The expression of p53 in Arab patients with GC correlates with aggressive tumor characteristics and is an independent prognostic factor. The combined analysis of p53 and p27 kip1 is of added prognostic value.

Juvenile ossifying fibroma (JOF) is an uncommon fibro-osseous lesion occurring in the facial bones. It is highly aggressive and has a strong tendency to recur. It has been recognized as a separate histopathological entity among the fibro-osseous group of lesions. Surgical resection is the preferred line of treatment. Here we report two cases of JOF who reported to the oral medicine and radiology department; the two cases had different clinical features, history, radiological appearance, and aggressiveness. Under the recent classification system, both cases were recognized as histopathological variants of JOF: one psammomatoid and the other trabecular.

Background: Gastric cancer is the most common cancer in Oman and a leading cause of cancer death. The variation in survival rates between countries and ethnic groups has been attributed to early detection policies, differences in clinicopathological features, treatment approaches, and biological characteristics. There were no previous reports on gastric cancer from Oman and very few studies on Asian Arabs. Aim: To evaluate the impact of clinicopathological and treatment variables on the survival prospects of Omani Arab patients diagnosed with gastric cancer. Methods: The medical records of 339 Omani Arab patients diagnosed with invasive gastric adenocarcinoma during the period 1993–2004 were retrospectively reviewed. The relative importance of clinicopathological features and surgical and medical treatments were assessed using univariate and multivariate analyses. Results: Most patients had distal ulcerating-type gastric cancer and presented at advanced stages. The median survival time for the entire cohort was 12 months (95% CI 9.7–14.4) with a 5-year overall survival rate of 16.7%. On univariate analysis of 237 patients who underwent surgical resection, the following positive prognostic factors emerged as significant: early overall TNM stage, early T stage, negative lymph nodes, tumor size <5 cm, ulcerating macroscopic appearance, and curative surgical attempt. The independent prognostic factors on multivariate analysis were T stage and lymph node involvement. Conclusion: The overall T and N stages are the most important determining factor for survival in Omani Arab patients. More efforts need to be made for the early detection of gastric cancer in developing countries such as Oman, while continuing to employ the standard surgical and medical treatments.

Ewing's sarcoma (ES) is an uncommon round cell tumor with an aggressive course affecting mainly children and young adults. Only 1% of cases is reported with jaw involvement and have mandibular predilection. Radiographic finding in ES reflect many destructive nature of the lesion, like osteolysis, cortical erosion, periostitis and soft tissue mass. A case of ES of the mandible is reported with special consideration to the radiological appearance.How to cite this article: Krishna KBB, Thomas V, Kattoor J, Kusumakumari P.

Context: World'spopulation is ageing and increase in geriatric population demands improved oral health care. Previous epidemiologic studies in general population of India and particularly in Kerala (state with maximum proportion of elderly) provided very little information about oral mucosal lesions in elderly. Aims: To find out the prevalence, pattern and distribution of oral mucosal lesions in geriatric patients and to explore their association with different study variables. Settings and Design: A descriptive, hospital-based, cross sectional study was conducted for a period of 9 months in the out-patient clinic, Department of Oral Medicine and Radiology, Government Dental College, Kozhikode (tertiary healthcare centre in Kerala, India). Methods and Materials: Participants aged 60 and above were selected by consecutive sampling. Data were collected through clinical examination and by using a structured proforma. Statistical Analysis Used: Descriptive statistics with tests of significance of associations were done. Results: The geriatric population (N=750, 66.89 ± 6.07, M: F=1.4:1), was recruited by screening 43,180, and 447 (67.29 ± 6.15, M: F=2:1) were identified having oral mucosal lesions withprevalence of 59.6% (95% CI=56.05–63.05). Most common lesion group was red and white (73.2%), followed by pigmented (15.5%). Oral mucosal lesions were significantly associated with age over 65, male gender, presence of habit and denture usage ( P < 0.05). Conclusions: The prevalence of oral mucosal lesions in geriatric people is high. Hence setting up of geriatric dental clinics, with appropriate preventive and palliative intervention strategies is mandatory.
