1/12. Dysmetabolic syndrome: multiple risk factors for premature adult disease in an adolescent girl.The clinical diagnosis of dysmetabolic syndrome in an adult defines a patient with abnormal glucose metabolism (or diabetes), hypertension, hyperlipidemia, and obesity. This disorder accelerates atherosclerosis and significantly raises the risk for cardiovascular events. With the marked rise in the prevalence of obesity in childhood, obesity-linked risk factors are being expressed at young ages. The case of a 12-year-old girl with dysmetabolic syndrome is described and discussed. Emerging clinical data now indicate that the presence of 1 risk factor for cardiovascular disease in an overweight child should prompt screening for additional clinical abnormalities, with the aim of finding treatable disorders.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
2/12. A review of the literature of Bardet-Biedl disease and report of three cases associated with metabolic syndrome and diagnosed after the age of fifty.bardet-biedl syndrome (BBS) is a genetic autosomal-recessive disease (formerly grouped with Laurence-moon-Biedl syndrome but considered today as a separate entity) characterized by abdominal obesity, mental retardation, dysphormic extremities (syndactyly, brachydactyly or polydactyly), retinal dystrophy or pigmentary retinopathy, hypogonadism or hypogenitalism (limited to male patients) and kidney structural abnormalities or functional impairment. The expression and severity of the various clinical BBS features show inter- and intrafamilial variability. This study focuses on three cases of familial BBS--two sisters and one brother (66, 64 and 51 years of age, respectively)--with the main cardinal findings of the disease plus a classic 'metabolic syndrome' (characterized by abdominal obesity, atherogenic dyslipidaemia, raised blood pressure, insulin resistance with or without glucose intolerance, and prothrombotic risk and proinflammatory states). One female patient (not affected by reproductive dysfunction) had three healthy offspring, while the other two patients were unmarried. Another severely affected brother died at 70 years of age; two other brothers are lean but affected by nephropathy, retinopathy, slight mental retardation, polydactyly, hypertension and thrombotic diseases, and had healthy offspring. BBS is a rather rare but severe syndrome that is often mis- or undiagnosed. Ophthalmologists, endocrinologists and nephrologists should be aware of BBS because of its adverse prognosis--early onset of blindness, associated findings of metabolic syndrome and increased vascular risk, and severe renal impairment (the most frequent cause of reduced survival and death early in life).- - - - - - - - - - ranking = 0.66666666666667keywords = obesity (Clic here for more details about this article) |
3/12. recurrence of insulin resistant metabolic syndrome following liver transplantation.Insulin resistant metabolic syndrome is a major clinical disorder including hyperlipidaemia, hypertension, impaired glucose tolerance and/or type 2 diabetes and central obesity, which are well established cardiovascular risk factors. We report the case of a 61-year-old woman who developed severe hypercholesterolaemia and hypertriglyceridaemia after liver transplantation. In her forties she had hypertension, mixed hyperlipidaemia, mild hyperglycaemia and moderate abdominal obesity, suggesting the presence of the metabolic syndrome. She had liver enzyme elevation and severe steatosis and hepatomegaly at ultrasonography. At age 52, cryptogenic liver cirrhosis was diagnosed and rapidly progressing liver failure developed. In 1992 she underwent liver transplantation. Seven years after transplant the patient had abdominal obesity, high blood pressure, marked hypercholesterolaemia, hypertriglyceridaemia and moderate elevation of alanine aminotransferase. She also had impaired glucose tolerance and markedly increased basal and post-glucose load plasma insulin levels. Steatohepatitis was demonstrated by serial liver biopsies. This is the first case that reports the recurrence of the metabolic syndrome following liver transplantation. We postulate that metabolic syndrome may have promoted fatty liver and subsequent progression to end stage liver disease. We also stress the need for careful management of the metabolic syndrome in order to decrease the long-term risk for cardiovascular disease.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
4/12. obesity and the metabolic syndrome.The prevalence of marked obesity is increasing rapidly among adults and has more than doubled in 10 years. Sixty-one percent of the adult population of the united states is overweight or obese. Americans are the fattest people on earth. Paradoxically these increases in the numbers of persons who are obese or overweight have occurred during recent years when Americans have been preoccupied with numerous dietary programs, diet products, weight control, health clubs, home exercise equipment, and physical fitness videos, each "guaranteed" to bring rapid results. overweight and obesity are also world problems. The world health organization estimates that 1 billion people around the world are now overweight or obese. Westernization of diets has been part of the problem. Fruits, vegetables, and whole grains are being replaced by readily accessible foods high in saturated fat, sugar, and refined carbohydrates. Since class 3 obesity (morbid or extreme obesity) is associated with the most severe health complications, the incidence of hypertension, stroke, heart disease, diabetes, and peripheral vascular disease will increase substantially in the future. Recently, obesity alone has been implicated in the development of cardiac hypertrophy and CHF. The metabolic syndrome associated with abdominal obesity, which includes insulin resistance, dyslipidemia, and elevated CRP levels, identifies subjects who have an increase in cardiovascular morbidity and mortality. Twenty to 25% of the adult population in the united states have the metabolic syndrome, and in some older groups this prevalence approaches 50%. The prevalence of overweight children in the united states has also been increasing dramatically, especially among non-Hispanic blacks and Mexican-American adolescents. overweight children usually become overweight adults. atherosclerosis begins in childhood. The degree of atherosclerotic changes in children and young adults can be correlated with the presence of the same risk factors seen in adults. As health providers, our direction is obvious!- - - - - - - - - - ranking = 2keywords = obesity (Clic here for more details about this article) |
5/12. diabetes mellitus type 2 in aviators: a preventable disease.INTRODUCTION: The current epidemic of obesity and resultant diabetes mellitus type 2 (DMT2) is a tsunami that will impact healthcare worldwide and lap over into aerospace medicine. Metabolic syndrome (MBS) is the major link between obesity and DMT2. methods: A review of U.S. Air Force Aeromedical Consult Service (ACS) records was accomplished looking at aviators with a diagnosis of DMT2. case reports of three flyers with DMT2 are presented and discussed. Other aeromedical agencies were contacted regarding their experiences and this information was summarized. A literature review on DMT2, obesity, and metabolic syndrome was accomplished. RESULTS: Of 70 charts for flyers identified with diabetes mellitus at the ACS between 1975 and 2000, over 95% were for DMT2. The mean body mass index for these aviators was 26.2. Currently, all services grant restricted waivers for some aviators with DMT2, none in high performance, single-seat aircraft. The FAA is currently allowing most flyers with stable DMT2 to operate aircraft in all categories with specific restrictions. DISCUSSION: obesity and metabolic syndrome are becoming increasingly prevalent in the aviation community. Aggressive actions to limit weight gain and identify those at risk for developing DMT2 must be considered for all populations.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
6/12. Metabolic syndrome.The metabolic syndrome is characterized by diabetes mellitus, obesity, hypertension, hyperlipidaemia and polycystic ovary syndrome. The lipid profiles of patient with metabolic syndrome is often characterized by the appearance of hypertrygliceridaemia and small, dense LDL-cholesterol, together with low HDL-cholesterol. patients with these abnormalities are at an increased risk for premature coronary artery disease. Treatment is a multifactorial process and includes modification of lifestyle factors such as diet and physical activity, weight reduction, correction of dyslipidemia, meticulous blood pressure and glycemic control. The case of a 36-year-old woman who develops metabolic syndrome is discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = obesity (Clic here for more details about this article) |
7/12. A mild form of Alstrom disease associated with metabolic syndrome and very high fasting serum free fatty acids: two cases diagnosed in adult age.alstrom syndrome (ALMS) is a very rare genetic autosomal recessive disease, characterized by early-onset severe abdominal obesity, impaired glucose tolerance or type 2 diabetes with insulin resistance, acanthosis nigricans, hyperlipidemia, childhood progressive retinal degeneration or retinitis pigmentosa and neurosensory hearing loss or deafness, cardiomyopathy, and other endocrine disorders. Genetic studies locate the ALMS gene on chromosome 2p12-13. The aim of this paper is to describe and discuss two unrelated cases of a mild ALMS form diagnosed after the age of 40 and 60, respectively, in adult fertile female patients. These cases showed several features of the disease plus other alterations characteristic of the classic "metabolic syndrome," including hypertension, hyperfibrinogenemia, and thrombotic states. Moreover, the patients had very high fasting serum free fatty acid (FFA) levels (2150 and 1919 micromol/L, respectively), which proved to be sensitive to inhibition by oral glucose tolerance test (OGTT)-induced hyperinsulinemia as well as to caloric restriction. ALMS may have an adverse prognosis and is often underdiagnosed. Its mild form, which allows a long survival, may also be associated with the late complications of the metabolic syndrome, leading to increased vascular risk.- - - - - - - - - - ranking = 0.33333333333333keywords = obesity (Clic here for more details about this article) |
8/12. bardet-biedl syndrome with syndrome X: a patient report.bardet-biedl syndrome (BBS) is an autosomal recessive condition with a wide spectrum of clinical features. The principal manifestations are rod-cone dystrophy (sometimes called atypical retinitis pigmentosa), postaxial polydactyly, central obesity, mental retardation, hypogonadism, and renal dysfunction. The clinical diagnosis of syndrome X defines a patient with abnormal glucose metabolism, hypertension, hyperlipidemia and obesity. We report here a 15 year-old girl with BBS presenting with syndrome X.- - - - - - - - - - ranking = 0.66666666666667keywords = obesity (Clic here for more details about this article) |
9/12. Metabolic syndrome and central retinal artery occlusion.BACKGROUND: The accumulation of risk factors for central retinal artery occlusion can be seen in a single person and might be explained by the metabolic syndrome. CASE REPORT: We presented the case of a 52-year-old man with no light perception in his right eye. The visual loss was monocular and painless, fundoscopy showed central retinal artery occlusion and the laboratory investigation showed the raised erythrocyte sedimentation rate of 105 mm/h and the raised c-reactive protein of 22 mg/l. Specific laboratory investigations and fluorescein angiography excluded the presence of vasculitis, collagen vascular diseases, hypercoagulable state and antiphospholipid syndrome. CONCLUSION: The patient met all the five of the National cholesterol education Program (NCEP) criteria for the metabolic syndrome: hypertension, abnormal lipid profile, abnormal glucose metabolism, obesity and hyperuricemia. Measurement of c-reactive protein is useful for the assessment of therapeutic systemic effect on any abnormality in the metabolic syndrome. Individual therapy for all risk factors in the metabolic syndrome is necessary to prevent complications such as cardiovascular, retinal vascular diseases and stroke.- - - - - - - - - - ranking = 0.33333333333333keywords = obesity (Clic here for more details about this article) |
10/12. weight loss in obese children carrying the proopiomelanocortin R236G variant.To acquire more information relative to the course of obesity in conditions of food restriction in subjects carrying mutations in the melanocortin signaling pathway, 710 obese children (mean age: 9.5 /-2.1 yr; mean z-score body mass index: 3.63 /-1.6) were genotyped for the proopiomelanocortin (POMC) R236G substitution, a variant which has been associated to early onset obesity, by restriction fragment length polymorphism (RFLP) analysis. Three children were heterozygotes for the R236G variant (0.4%). One of them had the metabolic syndrome. This variant was not found in 400 controls. The 3 probands followed a hypocaloric balanced diet and, after about 12 months, normalized their weight as well as fat mass and insulin resistance. The patient with the metabolic syndrome reversed this condition. These results show that a) the R236G substitution of POMC gene, although not a major cause of obesity among Italian obese children and adolescents, is associated with early onset obesity, and that b) inherited alterations of the melanocortin signaling pathway, independently of the degree of obesity, do not preclude the possibility to lose weight in mutated individuals following a hypocaloric diet.- - - - - - - - - - ranking = 1.6666666666667keywords = obesity (Clic here for more details about this article) |
