Objective:Raising cancer awareness among adolescents should lead to early diagnosis and improve their survival rate into adulthood. This study aims to identify knowledge of cancer risk factors, symptoms and barriers to seek medical help among Omani adolescents. Methods: A cross-sectional study with Omani adolescents (aged 15-17 years) has been conducted in six schools in Muscat, the capital of Oman. The general Cancer Awareness Measure questionnaire was used to collect the data. Results: A total of 481 adolescents participated. The average recognition of cancer risk factors and symptoms was low (36.8% and 39.6%, respectively). Cancer risk factors and/or symptoms significantly recognised more in girls compared to boys (χ 2 = 10.136; Odds ratio [OR] = 2.13 ; 95% confidence interval [CI]= 0.33-3.41; P = 0.001); older (age 17 year) versus younger (aged 15 and 16 years) (χ 2 = 6.075; OR = 11.68; 95% CI: 1.11-2.53; P = 0.014); those with existing co-morbidities compared to those without (χ 2 = 4.955; OR = 0.41; 95% CI: 0.18-0.92; P = 0.026); and those who knew someone with cancer compared to those who did not (χ 2 = 15.285; OR 2.70; 95% CI: 1.62-4.49; P <0.001). The majority of adolescents (88.8%) would seek medical help within the first two weeks of noting cancer symptoms. The most notable barriers to seek medical help were "emotional". Girls were experienced "emotional barriers" significantly more than the boys (χ 2 = 11.617; OR = 1.89; 95% CI: 1.31-2.72; P = <0.001). Conclusion: Adolescents in Oman showed poor cancer awareness with several "emotional" barriers. There is a need to establish and integrate effective cancer educational programs in school curriculums to raise the cancer awareness, address emotional barriers and encourage seeking early medical help. The program could potentially have a life-long impact on encouraging early cancer diagnosis and improving the cancer survival rate.

We report a case of a 31-year-old man who presented to the hospital with extensive deep vein thrombosis (DVT) complicated by pulmonary embolism (PE) after a recent trauma and prolonged immobilization. He underwent contrast venography that revealed features of May-Thurner syndrome (MTS). He was managed with therapeutic anticoagulation, inferior vena cava filter placement, mechanical clot aspiration, catheterdirected thrombolytic therapy, and left common iliac vein stenting.MTS is a vascular condition caused by the compression of the left common iliac vein by an overlying right common iliac artery against a vertebral body. This results in indolent endothelial changes secondary to the pulsating nearby artery as well as the compression increasing the susceptibility to venous thrombosis. Females are thought to be more prone to the condition due to the nature of their pelvic anatomy. Most patients are asymptomatic or present with unspecific symptoms, rendering the condition underdiagnosed. The gold standard diagnostic modality is contrast venography that reveals collaterals and a pressure gradient greater than 2 mmHg at rest across the stenotic region. Treatment is revolved around the removal of the thrombus along with the correction of the anatomical defect through interventional or surgical treatment to prevent a recurrence.Untreated MTS complicated with DVT carries a risk of potentially life-threatening complications, such as PE, iliac vein rupture, retroperitoneal hematoma, or refractory DVT that is difficult to treat. Due to the chronicity of this syndrome, its management plan differs from that of other causes of DVT. Proper identification of MTS carries a positive outcome in treating DVT secondary to MTS. Here we are going to discuss a case diagnosed with MTS complicated by saddle PE outlying the possible pathophysiology, clinical manifestation, diagnostic tools, and management of complicated MTS.

The incidence of end-stage kidney disease (ESKD) has been increasing over the past few years as a direct result of the growing percentages of individuals with metabolic syndrome. From 2001 to 2015 there were 2805 individuals diagnosed with ESKD in Oman with a growing number of patients undergoing renal transplant as the gold standard management of renal replacement therapy. Mycophenolate mofetil (MMF) is one of the most frequently used medications as a part of immunosuppressive medications in renal transplant specifically and solid organ transplant generally. We are reporting a case of MMF-induced colitis in a young female patient that underwent a living-related kidney transplant. She presented with a three-month history of watery non-bloody and afebrile diarrhea. Investigations confirmed the diagnosis of MMF-induced colitis. Histopathological examination of colonic biopsies obtained during the colonoscopy procedure showed mildly increased crypt apoptosis, mild architectural disarray, and focal crypt attenuation; features consistent with MMF-induced colitis. The patient was treated by stopping the causative agent and replacing it with another immunosuppressive medication, which led to complete resolution of the symptoms on follow-up appointments. In this case report, we highlighted the underlying mechanism, pathogenesis, and clinical features of MMF-induced colitis.
