LABORATORY FINDINGS: Hemoglobin, 13.2 gm/dL; mean corpuscular volume, 80 micron 3; white blood cell count, 7,200/mm3 (normal differential); platelet count, 137,000/mm3. serum: electrolytes, normal; blood urea nitrogen, 18 mg/dL; creatinine, 0.8 mg/dL; glucose, 308 mg/dL; total protein, albumin, liver enzymes, and creatine kinase, normal. urine: 1 glucose. Venereal disease test: nonreactive; hiv test: negative. DIFFERENTIAL diagnosis: dermatomyositis; heavy-metal poisoning; diabetic amyotrophy. HOSPITAL COURSE: The patient was given 50 mg/day of oral amitriptyline to alleviate the painful paresthesias and was switched to 20 U/day of subcutaneously injected neutral protamine Hagedorn (NPH) insulin to normalize the blood glucose level. Histologic studies of skin and muscle showed sun damage and neuropathic changes, respectively. There was no evidence of vasculitis. Screening for heavy-metal toxins produced negative results.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/20. ascites and weight loss in a child: due to congenital division of the right atrium.Congenital division of an atrial chamber is a very rare congenital malformation that more commonly affects the left atrium but which may, in rare circumstances, involve the right atrium. Such a divided right atrium may present with symptoms consistent with increased portal venous pressure. Reported is a case with unusual clinical presentation. The patient underwent resection of the dividing shelf with good postoperative results.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
3/20. 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 = 2keywords = pressure (Clic here for more details about this article) |
4/20. Rapidly progressive interstitial renal fibrosis associated with Chinese herbal medications.BACKGROUND/AIM: Nephropathy after ingestion of Chinese herbs is known as a rapidly progressive form of interstitial renal fibrosis after a slimming regimen containing aristolochic acid that was identified first in belgium. Intake of traditional Chinese herbal medicines is very popular in taiwan. So we looked for similar cases in our hospital. methods: From 1994 to 1998, we observed 20 Taiwanese patients who underwent renal biopsy for rapidly progressive renal failure of unknown origin. The medical history of these patients gave no clue to the origin of renal impairment, except for the administration of Chinese herbs before the development of renal failure in all cases. RESULTS: Although these patients took herbal medications from various sources for different purposes, their renal biopsy specimens showed strikingly similar histological patterns: extensive paucicellular interstitial fibrosis and tubular atrophy, but the glomeruli were apparently intact. They also had similar clinical features, such as a nearly normal blood pressure, obvious anemia, insignificant edema, low-grade proteinuria, and glucosuria. The renal function declined rapidly in most cases; 15 patients underwent dialysis within 3 months of renal biopsy, and 7 patients received emergency dialysis when they first came to our hospital. On clinical and morphological grounds, the nephropathy in our patients appears similar to Chinese herb nephropathy. CONCLUSIONS: Because of the diversity of the herbal regimens used, in addition to aristolochic acid, other unidentified phytotoxins may also play a role in this particular disease entity. There is a strong relation between rapidly progressive interstitial renal fibrosis and the consumption of Chinese herbs.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
5/20. Improvement in hypertrophic cardiomyopathy after significant weight loss: case report.A 17-year-old obese boy found to have familial apical hypertrophic cardiomyopathy on routine screening was enrolled in a weight loss program on the basis of the hypothesis that significant weight loss would improve his cardiac status. He was followed with serial dual-energy x-ray absorptiometry, electrocardiography, echocardiography, and blood pressure and pulse rate measurements. Within 1 year, he lost 49 kg, with a body mass index reduction from 43.6 to 28.1 kg/m2 and associated reductions in systolic blood pressure, diastolic blood pressure, pulse pressure, mean heart rate, rate pressure product, and echocardiographic indices of left ventricular mass that resulted in a change from the initial geometric finding of eccentric left ventricular hypertrophy to a "normal" left ventricular mass with minimal asymmetric apical left ventricular thickening. Significant weight loss in an obese adolescent with presumed familial apical hypertrophic cardiomyopathy was associated with striking improvement in cardiac functional indices, which could have profound implications for long-term cardiovascular risk.- - - - - - - - - - ranking = 5keywords = pressure (Clic here for more details about this article) |
6/20. Is weight loss possible in patients treated with thiazolidinediones? Experience with a low-calorie diet.BACKGROUND: weight gain is a frequent side-effect of thiazolidinediones, possibly related to fluid retention and stimulation of pre-adipocyte differentiation. methods: We report our experience with a low-calorie diet (800 cal, sodium content 1500 mmol/day) combined with behavior modification on eight patients treated with thiazolidinediones (six pioglitazone and two rosiglitazone). RESULTS: All patients had reported previous weight gain following treatment with thiazolidinediones. All patients lost weight over 12 weeks in the program with their mean /- SD body weight falling from 270 /- 54 lbs (123 /- 25 kg) to 244 /- 61 lbs (111 /- 28 kg) (p < 0.01). The weight loss observed was no different from that observed in 16 age- and gender-matched patients with type 2 diabetes not treated with thiazolidinediones (from 263 /- 54 lbs (120 /- 25 kg) to 239 /- 52 lbs (109 /- 24 kg); p < 0.01). Glycemic control improved while reducing insulin treatment. blood pressure control also improved and antihypertensive medications were decreased. The degree and time course of weight loss is no different from that in patients treated with other diabetic therapies and is associated with improved glycemic and blood pressure control. CONCLUSIONS: We conclude that a program of caloric restriction and behavior modification is effective in leading to weight loss in patients treated with thiazolidinediones. This effect is reassuring, since thiazolidinediones stimulate adipogenesis.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
7/20. Resolution of pseudotumor cerebri after bariatric surgery for related obesity. Case report.Two obese women, both of whom were 42 years of age, were examined for pseudotumor cerebri. Intracranial venography revealed increased pressure in the dural venous sinuses and the right atrium. The increased right atrial pressure was attributable to the patients' obesity. Both patients underwent bariatric surgery to achieve weight loss. Approximately 1 year later, a clinical evaluation showed that in both women the pseudotumor cerebri had resolved. Repeated measurements of dural venous pressure indicated that the patients' pressures had returned to normal. Obese patients with pseudotumor cerebri and stable visual symptoms are best treated with weight loss to avoid shunt placement or optic nerve sheath fenestration.- - - - - - - - - - ranking = 4keywords = pressure (Clic here for more details about this article) |
8/20. weight loss pressure on a 5 year old wrestler.The case is reported of a 5 year old boy who was pressured to lose weight in order to wrestle at a lower weight class. Although a minority of athletes engage in unhealthy weight management practices, this is an unusual case because of the age of the athlete and the influential role of a parent.- - - - - - - - - - ranking = 5keywords = pressure (Clic here for more details about this article) |
9/20. Does treating obesity stabilize chronic kidney disease?BACKGROUND: obesity is a growing health issue in the western world. obesity, as part of the metabolic syndrome adds to the morbidity and mortality. The incidence of diabetes and hypertension, two primary etiological factors for chronic renal failure, is significantly higher with obesity. We report a case with morbid obesity whose renal function was stabilized with aggressive management of his obesity. CASE REPORT: A 43-year old morbidly obese Caucasian male was referred for evaluation of his chronic renal failure. He had been hypertensive with well controlled blood pressure with a body mass index of 46 and a baseline serum creatinine of 4.3 mg/dl (estimated glomerular filtration rate of 16 ml/min). He had failed all conservative attempts at weight reduction and hence was referred for a gastric by-pass surgery. Following the bariatric surgery he had approximately 90 lbs. weight loss over 8-months and his serum creatinine stabilized to 4.0 mg/dl. CONCLUSION: obesity appears to be an independent risk factor for renal failure. Targeting obesity is beneficial not only for better control of hypertension and diabetes, but also possibly helps stabilization of chronic kidney failure.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
10/20. atrial fibrillation, sleep apnea and obesity.BACKGROUND: A 60-year-old male with obesity (body-mass index 43 kg/m(2)) presented with recurrent symptomatic atrial fibrillation (AF), which he had had since age 41 years. The AF was refractory to treatment with antiarrhythmic drugs. Pacemaker implantation for tachycardia-bradycardia syndrome was required as well as ablation for atrial flutter, and the patient underwent a total of four DC cardioversions. sleep studies showed mild to moderate obstructive sleep apnea, but continuous positive airway pressure was not tolerated. Pacemaker interrogations demonstrated mode-switch episodes, indicating continuing AF. He was scheduled for catheter ablation targeting pulmonary vein antral isolation. He embarked on a weight-loss program, which successfully reduced AF burden. INVESTIGATIONS: echocardiography, stress testing, polysomnography, pacemaker interrogations and c-reactive protein. diagnosis: AF, atrial flutter, tachycardia-bradycardia syndrome, obstructive sleep apnea and morbid obesity. MANAGEMENT: Antiarrhythmic drug therapy, DC cardioversion, anticoagulation, atrial flutter ablation, permanent pacemaker implantation, continuous positive airway pressure and weight loss.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
