1/50. Patient case studies.Three contrasting cases of obese patients with type 2 diabetes mellitus are presented, which illustrate the management difficulties faced by clinicians. The first raises the issue of when to commence an oral hypoglycaemic agent in a newly diagnosed but asymptomatic obese patient; the second case addresses the problem of when to commence insulin in the face of continuing weight gain and poor glycaemic control; the final case is an example of the vicious metabolic spiral which so many patients enter, with increasing body weight, poor diabetic control and associated co-morbidities. The discussion that follows each case presentation recognises the considerable cardiovascular risk faced by such patients and provides guidance about possible management pathways including adjunctive anti-obesity pharmacotherapy.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
2/50. Bone amyloidoma in a diabetic patient with morbid obesity.Bone localisations of amyloidosis are rare, usually diffuse and associated with myeloma. We report the case of a patient with massive obesity complicated by diabetes, hypertension, sleep apnea and liver steatosis, who complained of rapidly worsening bilateral polyradiculalgia of the lower limbs. After sufficient weight loss made nuclear magnetic resonance imaging feasible, a spinal tumour was visualised on the 5th lumbar vertebra, extending to soft tissues. Total excision was performed, and pathological studies revealed an amyloid bone tumour with no evidence of myeloma.- - - - - - - - - - ranking = 5keywords = obesity (Clic here for more details about this article) |
3/50. Diabetes management. Analysis of the American Diabetes association's clinical practice recommendations.Type 2 diabetes generally develops in persons older than age 45 and comprises more than 90% of the estimated 15 million diabetes cases identified in the united states. Due to the burgeoning population of older Americans and the increased prevalence of obesity and sedentariness, type 2 diabetes is nearing epidemic proportions. Tight glycemic control combined with good diet and regular exercise can reduce the incidence of complications associated with unchecked disease. To help physicians and patients achieve such objectives, the American Diabetes association publishes clinical practice recommendations that propose the most effective methods for screening, diagnosis, and disease management. The position statements presenting the standard of care for treatment of diabetes are reviewed and critiqued from an evidence-based medicine perspective.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
4/50. Acute lymphoblastic leukemia in one of two siblings with alstrom syndrome.alstrom syndrome is a rare autosomal recessive disease; less than 60 cases have been reported. No Chinese patient with this disease has been reported previously in the literature. Here, we describe an 11-year-old Chinese boy with this condition. His elder sister also had alstrom syndrome, and his father had non-insulin-dependent diabetes mellitus. Both siblings had degenerative retinopathy, obesity, mental retardation, perceptive hearing loss, short stature, non-insulin-dependent diabetes mellitus, nephropathy, hyperlipidemia, acanthosis nigricans, and hepatic dysfunction. The boy also developed acute lymphoblastic leukemia, which was confirmed by cytochemistry and immunophenotyping findings. He received chemotherapy and radiotherapy for the malignancy. The present case suggests that acute lymphoblastic leukemia may be coincident with or may be a previously undescribed systemic manifestation of alstrom syndrome.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
5/50. Effects of a single bout of exercise and exercise training on steroid levels in middle-aged type 2 diabetic men: relationship to abdominal adipose tissue distribution and metabolic status.Lower androgen levels have been suggested to be associated with type 2 diabetes and central obesity and are probably involved into the development of atherosclerosis. The present study investigates the effect of acute and chronic exercise on dehydroepiandrosterone (DHEA) levels in relation to abdominal fat distribution and metabolic status in type 2 diabetes. Twenty weight-stable, middle-aged males with type 2 diabetes were enrolled in the study and participated in a submaximal (VO(2) peak) and moderate (50% VO(2) peak) exercise bout. The subjects were randomly assigned either to a trained or a control group, respectively. Physical training consisted of an 8 week program of aerobic exercise (75% VO(2) peak, 45 min), twice a week and intermittent exercise, once a week, on a bicycle ergometer. Acute exercise significantly increased DHEA and testosterone (T) levels. Physical training increased VO(2) peak (42%, p <0.001), insulin sensitivity index (K(ITT) ) (57.5%, p <0.02), and basal DHEA levels (36%, p <0.05), and decreased HbA1c (29%, p <0.001), visceral adipose tissue (VAT) (44%, p <0.01) and subcutaneous adipose tissue (SAT) levels (18%, p <0.01). Body weight, BMI and insulin, T levels were not modified. Changes in DHEA levels were not correlated with changes in insulin sensitivity and abdominal fat distribution. In conclusion, exercise training favourably affects DHEA levels independently of improvements of metabolic status and abdominal fat distribution in patients with type 2 diabetes.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
6/50. The clinical implications of insulin resistance.insulin resistance is a prime risk factor associated with atherosclerosis and thrombosis. Other risk factors include dyslipidemia, obesity, and hypertension. The constellation of those factors, which is known as the cardiovascular dysmetabolic syndrome, increases the risk of macrovascular disease. insulin resistance may contribute directly to cardiovascular disease and may also act as a precursor of diabetes, which is also associated with an increased risk of macrovascular disease. insulin resistance can be difficult to assess clinically, but it is invariably present in patients with type 2 diabetes, impaired fasting glucose, or impaired glucose tolerance. Treatment of insulin resistance includes diet, exercise, smoking cessation, strict control of hypertension, aggressive treatment of lipid abnormalities, and keeping the hemoglobin A1c level below 7%. New oral agents improve glycemic control for those with diabetes or insulin resistance, but their role in reducing the risk of macrovascular disease is undetermined.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
7/50. A case of obesity, diabetes and hypertension treated with very low calorie diet (VLCD) followed by successful pregnancy with intrauterine insemination (IUI).The patient was a 32-year-old obese woman with a history of type 2 diabetes and hypertension for 6 years. Although she was treated with antihypertensive agents and intensive insulin therapy, her hyperglycemia was difficult to control. She wanted to have a baby but pregnancy was not recommended because her diabetes was under poor control and the use of antihypertensive medication. To achieve good control of obesity, diabetes and hypertension, she was admitted to our clinical department for weight reduction using very low calorie diet (VLCD). During VLCD she had a 19.8 kg reduction in body weight and her blood glucose and blood pressure were in good control without the use of drugs. Five months later, she became pregnant after the fourth trial of intrauterine insemination (IUI) and gave birth to a female baby under insulin therapy. This is the first report that showed the usefulness of VLCD for prepregnant control of glucose metabolism and blood pressure in an obese hypertensive patient with type 2 diabetes mellitus.- - - - - - - - - - ranking = 5keywords = obesity (Clic here for more details about this article) |
8/50. Type 2 diabetes in an aviator, protein diet vs. traditional diet: case report.An experienced helicopter pilot with hypertension, hyper-triglyceridemia, elevated cholesterol, obesity, and diabetes is treated with a high-protein, low-carbohydrate diet. In 3 months, he loses 35 lbs, is normotensive without medication, cholesterol and triglycerides show significant reduction, fasting blood glucose and 2-h post glucose load are normal. At follow-up 1 yr later he has maintained hemoglobin A1C in the low 5 range. The protein diet is discussed and compared with the traditional dietary approach for type 2 diabetes.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
9/50. Syndrome of lipodystrophy, hyperlipidemia, insulin resistance, and diabetes in treated patients with human immunodeficiency virus infection.OBJECTIVE: To describe the syndrome of lipodystrophy, hyperlipidemia, insulin resistance, and diabetes in patients with human immunodeficiency virus (hiv) infection treated with protease inhibitor drugs. methods: This is a case series of patients referred from an infectious disease clinic to a diabetes-endocrinology clinic in an academic medical center because of severe metabolic problems that occurred during the course of otherwise-successful treatment of hiv infection. The clinical course, abnormalities on physical examination, laboratory data, and complications are described and analyzed. The pathogenesis of the syndrome is discussed and compared with that of type 2 diabetes, lipoatrophic diabetes, and mouse models of lipodystrophy. RESULTS: In six male patients receiving antiretroviral therapy for hiv infection, a syndrome of lipoatrophy of the face, legs, and buttocks, hyperlipidemia (predominantly hypertriglyceridemia), and type 2 diabetes mellitus was noted. Two patients had pronounced abdominal obesity, in contrast to their thin extremities. Five of the six patients were receiving protease inhibitor drugs, which have been thought to contribute to metabolic abnormalities. In two patients, ischemic heart disease had developed. CONCLUSION: protease inhibitors frequently cause insulin resistance and lipoatrophy in subcutaneous adipose tissue. These abnormalities are associated with visceral adiposity, hyperlipidemia, diabetes, and cardiovascular consequences and represent an important and unsolved problem in the treatment of hiv-infected patients.- - - - - - - - - - ranking = 1keywords = obesity (Clic here for more details about this article) |
10/50. Type 2 diabetes in obese white children.We report four white adolescents aged 13 to 15 years (three females, one male) from the south and west region of england who presented with type 2 diabetes mellitus associated with significant obesity (body mass index more than 3SDS) in the past two years. Although these are the first reported obese, white cases from the UK to present with diabetes, we believe this clinical scenario will become more prevalent given the epidemic of childhood obesity in this country.- - - - - - - - - - ranking = 2keywords = obesity (Clic here for more details about this article) |
