3342. Malakoplakia of the colon associated with colonic adenocarcinoma diagnosed in colonic biopsies Full Text available with Trip Pro

Malakoplakia of the colon associated with colonic adenocarcinoma diagnosed in colonic biopsies Malakoplakia, typically involving the urinary tract, is an uncommon form of chronic inflammation caused by chronic infections and characterized by accumulation of macrophages. It has also been found in many other sites such as the gastrointestinal tract, pancreas, liver, lymph nodes, skin, respiratory tract, adrenal gland, vagina and brain. We present a case of a 64-year-old man referred to our (...) hospital with cachexia and radiologic evidence of metastatic tumor of the liver. Colonoscopy revealed a large malignant - appearing polypoid mass of the ascending colon and multiple distinct polyps throughout the rest of the colon. Biopsies of the ascending colon mass confirmed the diagnosis of adenocarcinoma. Histological examination of two of the other polyps revealed malakoplakia which was characterized by aggregates of granular histiocytes with Michaelis - Gutmann bodies and histochemically

3343. Proteomic analysis of peripheral T lymphocytes, suitable circulating biosensors of strictly related diseases Full Text available with Trip Pro

between changes in T cell protein expression patterns and specific diseased conditions. In particular, two hyperandrogenic syndromes were studied, sharing many clinical and biochemical signs: polycystic ovary syndrome (PCOS) and congenital adrenal hyperplasia (CAH). Comparison of proteomic maps of T lymphocytes derived from patients affected by PCOS or CAH with those derived from healthy subjects showed that 14 proteins are expressed differentially in both PCOS and CAH, 15 exclusively in PCOS and 35 (...) exclusively in CAH. Seventeen of these proteins have been identified by mass spectrometry analysis. Furthermore, proteomic data mining by hierarchical clustering was performed, highlighting T lymphocytes competence as a living biosensor system.

3344. Aggressive and non-aggressive personalities differ in oxidative status in selected lines of mice (Mus musculus) Full Text available with Trip Pro

Aggressive and non-aggressive personalities differ in oxidative status in selected lines of mice (Mus musculus) Mice selected for aggression and coping (long attack latency (LAL), reactive coping strategy; short attack latency (SAL), pro-active coping strategy) are a useful model for studying the physiological background of animal personalities. These mice also show a differential stress responsiveness, especially in terms of hypothalamic-pituitary-adrenal axis reactivity, to various challenges (...) . Since the stress response can increase the production of reactive oxygen species, we predicted that the basic oxidative status of the lines could differ. We found that LAL showed higher serum antioxidant capacity (OXY) than SAL, while no differences emerged for reactive oxygen metabolites (ROMs) or the balance between ROMs and OXY, reflecting oxidative stress. Moreover, the lines showed inverse relationships between ROMs or OXY and body mass corrected for age. The results indicate that variation

3345. A 5-year-old girl with a congenital ganglioneuroma diagnosed by fine needle aspiration biopsy: a case report Full Text available with Trip Pro

A 5-year-old girl with a congenital ganglioneuroma diagnosed by fine needle aspiration biopsy: a case report Ganglioneuroma is a rare, benign, neuroblastic tumor arising mainly from the central or peripheral autonomic nervous system, especially the sympathetic system. The most affected anatomical sites are the posterior mediastinum, retroperitoneum, adrenal gland and head and neck soft tissue. In the current literature, reports of ganglioneuroma diagnosed by fine-needle aspiration and its (...) cytological appearance are scarce.A 5-year-old girl presented with a mass in the cervical region since birth. Laboratory routine tests were within normal limits, ultrasonography demonstrated a solid and well-circumscribed lesion in the soft tissues of the cervical region. Fine needle aspiration biopsy was carried out, and the obtained smears showed a mixture of mature ganglion cells and groups of spindle cells suggestive of schwann cell origin. A diagnosis of ganglioneuroma was suggested. Core biopsy

3346. Night eating status and influence on body weight, body image, hunger, and cortisol pre- and post- Roux-en-Y Gastric Bypass (RYGB) surgery Full Text available with Trip Pro

Night eating status and influence on body weight, body image, hunger, and cortisol pre- and post- Roux-en-Y Gastric Bypass (RYGB) surgery Night Eating Syndrome is a common disorder in severely obese individuals and may be associated with hypothalamic pituitary adrenal (HPA) axis dysregulation. This study compared night eaters (NE) and comparably obese controls (C) pre- and post-Roux-en- Y Gastric Bypass surgery at 2 and 5 months, following an overnight fast on hormonal measures associated (...) with HPA axis and related appetite and psychological measures. There were 24 (10 NE, 14 C) clinically severely obese participants (body mass index =47.0+/-8.4 SD). At pre-surgery baseline, afternoon fasting hunger ratings differed significantly and were lower for NE than for C (p=0.01). Eight of the participants (4 NE, 4C) returned for all 3 study visits. At 5 months post-surgery, NE and C did not differ in weight loss, reductions in waist circumference, insulin levels, and insulin resistance

Pheochromocytomas and secreting paragangliomas Catecholamine-producing tumors may arise in the adrenal medulla (pheochromocytomas) or in extraadrenal chromaffin cells (secreting paragangliomas). Their prevalence is about 0.1% in patients with hypertension and 4% in patients with a fortuitously discovered adrenal mass. An increase in the production of catecholamines causes symptoms (mainly headaches, palpitations and excess sweating) and signs (mainly hypertension, weight loss and diabetes

Effect of dietary soluble fiber on neurohormonal profiles in serum and brain of rats This study was conducted to investigate the effect of dietary soluble fiber administration and /or high fat diet on serum and brain neurohormonal profiles, adipose tissue mass and body weight gain in Sprague-Dawley rats. Four groups of rats were respectively fed 10% fat diet (C), 10% fat plus pectin diet (P), 20% fat diet (HFC) and 20% fat plus pectin diet (HFP) for 4 weeks. In HFP group, the food and energy (...) intake, body weight gain, FER including fecal excretion were the smallest (p<0.05). Serum HDL-cholesterol, triglyceride and glucose level were also the lowest in HFP group (p<0.05). The weight of brain, epididymal fat pad and adrenal gland except liver didn't show any significant differences among groups. Interestingly serum norepinephrine concentration of HFP group tended to be higher, but dopamine concentration tended to be lower than those of HFC group. However serum catecholamine concentration

3352. Laparoscopic Adrenalectomy for Pheochromocytoma Versus Other Surgical Indications Full Text available with Trip Pro

Laparoscopic Adrenalectomy for Pheochromocytoma Versus Other Surgical Indications Laparoscopic adrenalectomy is widely recognized as the preferred technique for surgical removal of adrenal masses. This study aimed to evaluate the outcomes of consecutive laparoscopic adrenalectomies performed at a high-volume referral center and compare operative results for pheochromocytomas with that of other adrenal diseases.We retrospectively reviewed a single surgeon's experience with laparoscopic (...) adrenalectomy performed between July 2002 and June 2007. Patient records were analyzed in regards to demographics, pathology diagnoses, operative time, postoperative complications, tumor size, hospital stay, among others.Seventy-two consecutive laparoscopic adrenalectomies were performed on 70 patients, including 2 bilateral adrenalectomies and one partial adrenalectomy. Surgical indications included pheochromocytoma (n=11), aldosteronoma (n=26), malignant adrenal disease (n=4), nonfunctioning adenomas (n

3354. Undiagnosed Pheochromocytoma: The Anesthesiologist Nightmare Full Text available with Trip Pro

Undiagnosed Pheochromocytoma: The Anesthesiologist Nightmare A male, 62 years of age, presented to the operating room for the removal of a right adrenal mass. Induction of anesthesia triggered a severe hypertensive crisis resistant to high doses of nitroprusside, nitroglycerin and labetalol. The crisis was ultimately resolved with the administration of 5 mg bolus of phentolamine. Surgery was canceled, the patient was transported to the intensive care unit with a continuous drip of phentolamine (...) . High urinary and plasma catecholamines suggested the presence of pheochromocytoma. Three weeks of oral phenoxybenzamine therapy subsequently allowed uneventful induction of anesthesia and open adrenalectomy. Pathologic examination of the resected adrenal tissue confirmed the presence of pheochromocytoma. Anesthetic drugs can exacerbate the life-threatening cardiovascular effects of catecholamines secreted by pheochromocytomas. Treating patients preoperatively with alpha-adrenergic blockade

3355. Enhanced cortisol production rates, free cortisol, and 11β-HSD-1 expression correlate with visceral fat and insulin resistance in men: effect of weight loss Full Text available with Trip Pro

-1) gene expression by quantitative RT-PCR from subcutaneous biopsies. Increased CPR and FC correlated with increased IAF, but not SQF, and with decreased S(I). Increased 11beta-HSD-1 gene expression correlated with both IAF and SQF and with decreased S(I). With weight loss, CPR, FC, and MCR did not change compared with baseline; however, with greater loss in body fat than lean mass during weight loss, both CPR and FC increased proportionally to final fat mass and IAF and 11beta-HSD-1 decreased (...) compared with baseline. These data support a model in which increased hypothalamic-pituitary-adrenal activity in men promotes selective visceral fat accumulation and insulin resistance and may promote weight regain after diet-induced weight loss, whereas 11beta-HSD-1 gene expression in SQF is a consequence rather than cause of adiposity.

and reduced adiponectin levels. Metformin therapy in SGA-PP girls attenuates the hyperinsulinemia, the adrenal androgen excess, and the proinflammatory state. In contrast, GH therapy in SGA-SS children promotes height gain but may induce hyperinsulinemia. Both groups are associated with increased risk markers for future cardiovascular disease. Therefore, we studied markers of inflammation in both SGA subpopulations at baseline and after their respectively corrective therapies. SGA-PP girls (n = 33; mean (...) age, 8 yr; body mass index, 18.5 kg/m(2)) were randomized to remain untreated or to receive metformin (425 mg/d) for 6 months. SGA-SS children (n = 29; mean age, 7 yr; body mass index, 14.7 kg/m(2)) were randomly assigned to remain untreated or to receive GH (60 mug/kg/d). In SGA-PP girls, the mean neutrophil count (4.0 x 1000/mm(3)) was more than 2 sd above the mean reference level (2.8 x 1000/mm(3), P < 0.001); this remained stable over 6 months in untreated girls but dropped in metformin

-adrenal (HPA) system activity. Therefore, the aim of the present study was to examine whether insulin sensitivity improves during anti-depressive treatment in depressed patients with declining HPA system activity.Eighty inpatients with an episode of major depressive disorder (DSM-IV criteria) were treated in a double-blind, randomized protocol with either amitriptyline or paroxetine over a period of 5 weeks. After 6 drug-free days, an oral glucose tolerance test was performed on day 1 and again 35 (...) days after antidepressive treatment. For quantification of free cortisol levels, saliva was obtained daily at 8:00 a.m. during weeks -1 (washout) and 5. The study was conducted from May 2005 to December 2005.The insulin sensitivity index(Matsuda) increased in only those patients who remitted from major depressive disorder as a result of treatment with either antidepressant (F = 7.0, df = 1,74; p < .01), while correcting for body mass index. Further, cortisol concentrations declined in remitters

3358. Combining growth hormone releasing hormone-arginine and synacthen testing diminishes the cortisol response. Full Text available with Trip Pro

Combining growth hormone releasing hormone-arginine and synacthen testing diminishes the cortisol response. The GHRH/arginine test and short synacthen test (SST) have been validated as safe alternatives to the insulin tolerance test for the assessment of the GH reserve and hypothalamic-pituitary-adrenal axis integrity, respectively. However, these two tests are usually performed separately. The objective was to see whether the synacthen and GHRH/arginine tests could be combined to save time (...) , patients had a lower peak cortisol response with a mean difference of 116 nmol/liter (95% confidence interval, 52.54 to 179.37; P < 0.001), and one patient with a normal response on the SST had a subnormal cortisol response in the combined test. Similar lower peak cortisol responses were observed in males and females with combined test. The difference between the peak cortisol responses showed no significant correlation with age (r = 0.123; P = 0.58) or with the body mass index (r = -0.376; P = 0.09

3359. Use of the electrothermal bipolar vessel system (EBVS) in laparoscopic adrenalectomy: a prospective study. (Abstract)

Use of the electrothermal bipolar vessel system (EBVS) in laparoscopic adrenalectomy: a prospective study. Since laparoscopic adrenalectomy (LA) has been adopted as the gold standard for the treatment of adrenal diseases, the development of technology for vascular control and dissection manoeuvres, amongst other things, may play a pivotal role in its further improvement. We report our experience with the electrothermal bipolar vessel sealing (EBVS) device for LA.From January 2004 to January (...) 2006, 50 patients (pts) undergoing LA were selected and randomized for use of the EBVS (25 pts, group A) versus the UltraSonic Shears (USS) device (25 pts, group B). Age, sex, body mass index (BMI), previous surgery and associated diseases were similar between the two groups. The main surgical parameters collected for each patient (pt) concerned operative time, major and minor complications, conversion rate, blood loss, hospital stay and histology.There was no mortality in either group.
