A case-control study among Singapore Armed Forces' newly enlisted Servicemen was conducted to examine factors associated with male obesity. Four hundred and fifty-nine individuals from the Obese Basic Military Training program were selected as "cases" (average age: 19.5, body mass index: 30.4) and another 340 individuals were selected from the Normal Basic Military Training program as "controls" (average age: 19.3, body mass index: 21.4). Information such as family background, socioeconomic factors, and lifestyle practices were captured using facilitator-led questionnaires. Several variables were significantly associated with obesity after adjustments for possible confounders. These include childhood obesity (odds ratio [OR] = 2.06), less than an hour of exercise per day (OR = 2.97), Indian ethnicity (OR = 2.22), specific education backgrounds (especially that of Institute of Technical Education-OR = 2.75), father's employment at nonmanagerial/professional jobs (OR = 1.52), mother's employment at managerial/professional jobs (OR = 2.02), regular smoking (OR = 1.73) and alcohol consumption (OR = 2.26), 6 hours or less of sleep (OR = 3.73), obesity among family members (OR = 1.86 for mother; OR = 2.98 for siblings), parental history of diabetes mellitus (OR = 2.22 for father; OR = 2.70 for mother), and eating at inexpensive local food stalls (OR = 1.82). Our study found that a number of factors, ranging from personal and family backgrounds to lifestyle choices, were significantly associated with obesity among male youths.
Penile metastasis from prostate adenocarcinoma is rare and the disease is usually disseminated at presentation. We present a case of an 83-year-old man with solitary metastasis to the penis from prostate adenocarcinoma. The clinical presentation and imaging features of penile metastasis from prostate cancer and the other primary penile tumors are discussed.
Background
Painless aortic dissection presenting with seizure and acute liver failure is uncommon. We described a case of early recognition leading to successful treatment of painless aortic dissection with atypical presentation.
Case summary
A young lady presented with generalized tonic-clonic seizures coupled with hepatitic pattern of deranged liver function test. Examination revealed blood pressure of 99/75 mmHg and hepatic flap. Electrocardiography showed sinus tachycardia. Urgent bedside echocardiography showed preserved cardiac function without significant valvular pathology, but noted a moderate pericardial effusion. Abdominal Ultrasound excluded liver cirrhosis or biliary obstructions. Viral hepatitis serologies and anti-liver panel were negative. She was progressively hypotensive with concurrent acute liver failure and oliguric acute kidney injury. Despite no chest pain, her rising serum troponin and widened mediastinum prompted an urgent computed-tomography aortogram, which showed a 4.3 cm dilatation of ascending thoracic aorta with acute haemopericardium and cardiac tamponade. She was diagnosed with malperfusion syndrome from Stanford type A aortic dissection. She underwent emergent ascending aorta and aortic arch repair and dialysis. She experienced complete recovery in her kidney, liver, and neurological function post-operatively.
Discussion
Painless aortic dissection masquerade as acute liver failure is uncommon. We describe a successful early recognition of malperfusion syndrome from painless aortic dissection, thus providing window for timely, life-saving intervention. Clinical challenges in this case include: (i) atypical presentation of aortic dissection, (ii) worsening acute liver failure which could lead to unnecessary liver transplantation, and (iii) risk of contrast-induced nephropathy in the setting of acute renal failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
