3361. Prospective, randomized comparison of transperitoneal versus retroperitoneal laparoscopic adrenalectomy. (Abstract)

patient age greater than 80 years, body mass index greater than 40, bilateral adrenalectomy and significant prior abdominal surgery in the quadrant of interest. Mean followup was 5.96 years in the 2 groups.The groups were matched in regard to patient age (p = 0.84), body mass index (p = 0.43), American Society of Anesthesiologists class (p = 0.81) and laterality (p = 0.12). Median adrenal mass size was 2.7 cm (range 1 to 9) in the TLA group and 2.6 cm (range 0.5 to 6) in the RLA group (p = 0.83). TLA (...) Prospective, randomized comparison of transperitoneal versus retroperitoneal laparoscopic adrenalectomy. We report a prospective, randomized comparison of transperitoneal laparoscopic adrenalectomy (TLA) vs retroperitoneal laparoscopic adrenalectomy (RLA) for adrenal lesions with long-term followup.Between December 1997 and November 1999, 57 consecutive eligible patients with surgical adrenal disease were prospectively randomized to undergo TLA (25) or RLA (32). Study exclusion criteria were

3362. Efficacy of a long-acting growth hormone (GH) preparation in patients with adult GH deficiency. Full Text available with Trip Pro

Efficacy of a long-acting growth hormone (GH) preparation in patients with adult GH deficiency. Treatment of adult GH deficiency (AGHD) with daily injections of GH results in decreased adipose mass, increased lean body mass (LBM), increased bone mineral density, and improved quality of life.This study seeks to determine whether a depot preparation of GH given every 14 d would lead to comparable decreases in trunk adipose tissue as daily GH.This open-label, randomized study compares subjects (...) absorptiometry.The percentage of the trunk region that is fat increased by 0.4 in the no treatment group, but decreased by 3.2 (P = 0.001 vs. untreated) in the GH depot group and by 2.5 (P < 0.004 vs. untreated) in the daily GH group. Visceral adipose tissue area decreased by 9.1% in the GH depot group and by 6.8% in the daily GH group. LBM and high-density lipoprotein increased in both treatment groups. Side effect profiles were similar. Three subjects receiving GH experienced serious episodes of adrenal

3363. Adiposity in children born small for gestational age. Full Text available with Trip Pro

, this relationship is not restricted to foetal undernutrition or intrauterine growth retardation, but is also found for children born premature, or for high birth weight children. Furthermore, early post-natal nutrition, and more specifically catch-up growth, appear to modulate cardiovascular risk as well. Intrauterine growth retardation can be induced in animal models by energy/protein restriction, or ligation of uterine arteries. In such models, altered glucose homeostasis, including low beta-cell mass, low (...) insulin secretion and insulin resistance is observed after a few weeks of age. In humans, several studies have confirmed that children born SGA have insulin resistance as adolescents and young adults. Alterations of glucose homeostasis and increased lipid oxidation can indeed be observed already in non-diabetic children born SGA at early pubertal stages. These children also have alterations of stature and changes in body composition (increased fat mass), which may contribute to the pathogenesis

3364. Primary breast lymphoma in a male patient. (Abstract)

Primary breast lymphoma in a male patient. Primary lymphoma of the male breast is extremely rare. We report a case of a diffuse large B-cell lymphoma in a male patient. A 67-year-old man presented with a palpable mass in the right breast and ipsilateral axillary lymphadenopathy. At operation a 6 x 5 x 4-cm mass was excised, and a frozen section demonstrated malignancy. A modified radical mastectomy was then performed, together with axillary lymph node clearance. Histological examination (...) established the diagnosis of a primary non-Hodgkin's lymphoma of the breast. The patient was referred for chemotherapy and died a year later from systemic disease involving the adrenals. The importance of early diagnosis is emphasized; this should be based on an excisional biopsy or aspiration cytology. As patients with primary breast lymphoma (PBL) have a better prognosis than those with carcinoma of the breast or patients with extranodal lymphomas, a multidisciplinary approach including surgery

3365. Retroperitoneal hemangioma of infancy. (Abstract)

Retroperitoneal hemangioma of infancy. A premature infant presented with an incidental finding of a mass in the retroperitoneum adjacent to the adrenal gland seen on a renal ultrasound study. A clinical diagnosis of neuroblastoma was made based on imaging and laboratory studies; however, upon resection, histological examination revealed a cellular capillary hemangioma of infancy. Hemangioma should be considered in the differential diagnosis of asymptomatic retroperitoneal mass lesions

3366. Normotensive pheochromocytoma: institutional experience. (Abstract)

, and one patient had normal values. One patient did not undergo the urinary metanephrine assay. Imaging of the abdomen showed seven adrenal and two extra-adrenal masses (eight had computed tomography scans of the abdomen, and one underwent ultrasonography). After selective alpha-adrenergic blockade (prazosin), surgery was performed. Six patients required infusion of sodium nitroprusside intraoperatively. The final histopathology was pheochromocytoma in all patients. Metanephrine levels were normal (...) during the follow-up. Normotensive pheochromocytomas are a distinct entity, and all adrenal incidentalomas should be investigated for catecholamine hypersecretion. We support the use of preoperative alpha-adrenergic blockade, and these patients should be treated along the same lines as hypertensive pheochromocytoma.

3367. Fetus in fetu--diagnostic criteria and differential diagnosis--a case report and literature review. (Abstract)

. Pathologic examination showed an irregular fetiforme mass, weighing 8 g, attached to an amniotic sac by a rudimentary umbilical cord with 2 rudimentary limbs, vertebral bodies, encephalus, coroidal plexus, stomach, duodenum, bowel, adrenal glands, upper and lower respiratory tissue, spleen, lymphoid tissue, single cavity heart, and kidney. Molecular analysis using an informative genetic marker, for uniparental isodisomy of chromosomes 14 and 15 showed no genetic difference between the host infant (...) Fetus in fetu--diagnostic criteria and differential diagnosis--a case report and literature review. Fetus-in-fetu (FIF) is a rare congenital condition in which a vertebrate fetus is incorporated within its twin. The authors report the case of a newborn boy with prenatal ultrasonographic diagnosis of intraabdominal mass, provoking compression of the left kidney. Plain abdominal radiography, ultrasonography, and computer tomography showed a cystic mass containing multiple calcifications

3368. Experience with laparoscopic adrenalectomy in children. (Abstract)

and girls. Case selection was based mainly on the size of the lesion and its localized nature as seen on the imaging studies. The transperitoneal approach was used in all cases.Eleven laparoscopic adrenalectomies were performed in 10 children (1 was bilateral adrenalectomy). Presenting features were virilization (n = 3), Cushing's syndrome (n = 1), antenatally detected adrenal cyst (n = 1), hypertension (n = 1), hepatomegaly (n = 1), loin pain with hematuria (n = 1) and an incidental adrenal mass (n = 1 (...) ). One was a child with stage IV adrenal neuroblastoma postchemotherapy for resection of the residual tumor. On imaging studies, the tumors were between 2.8 and 7 cm in their largest dimension. Operating time ranged from 118 to 180 minutes in the unilateral resections, whereas the bilateral laparoscopic adrenalectomy required 330 minutes. Two had to be converted to open procedures. Postoperative hospital stay was between 2 and 15 days. Pathologic diagnoses were as follows: adrenal cortical adenoma (n

3369. Extralobar pulmonary sequestration mimicking neuroblastoma. (Abstract)

Extralobar pulmonary sequestration mimicking neuroblastoma. Extralobar pulmonary sequestration is a congenital pulmonary malformation, which rarely may be present in an intra-abdominal location. We describe a 1-week-old newborn with an intra-abdominal sequestration, which presented to us as an antenatally diagnosed suprarenal mass. Intra-abdominal extralobar sequestration should also be kept in differential diagnosis in cases of masses in the suprarenal location.

mass ranging from 2 to 13 cm in diameter with a basal density of 12 to 28 Hounsfield Units and strong heterogeneous enhancement following contrast injection. The surgical procedure consisted of controlateral (n = 5), ipsilateral (n = 2), and bilateral (n = 1) laparoscopic adrenalectomy, whereas three patients underwent controlateral open adrenalectomy for adrenal mass >10 cm. Nine patients were recurrence-free with a median follow-up of 34 months. In the remaining two patients, lung metastases were (...) Laparoscopic adrenalectomy for metachronous metastasis from renal cell carcinoma. Metachronous adrenal metastases (AM) from renal cell carcinoma (RCC) are rare. We report our experience of surgical resection in this setting, with particular respect to laparoscopic approach and long-term outcome.A retrospective review of 11 patients who underwent adrenalectomy for metachronous AM from RCC was conducted between 2002 and 2005 in a tertiary referral center.CT scan findings were those of an adrenal

complications, the authors retrospectively investigated the long-term morbidity of patients who had reached adulthood.Sixteen patients with neuroblastoma currently 18 years of age or older were incorporated into the study. All were non-mass screening cases, and 13 of the patients had undergone aggressive surgery, whereas the remaining 3 cases had received aggressive chemotherapy.In the 13 patients who had undergone aggressive surgical treatment, a unilateral atrophy of the kidney was noted in 2 cases (...) of adrenal and retroperitoneal neuroblastomas, respectively. Dry ejaculation was noted in one case of a giant presacral neuroblastoma. A maldevelopment of the unilateral lower extremity was also noted in another case with a presacral tumor, which had been resected by abdominal and sacral approaches. In the 3 patients who had undergone aggressive chemotherapy, severe hearing loss occurred in 2 cases. However, social adaptation was well preserved in all 16 cases.Treatment-specific complications were found

3373. Evaluation of the cardiovascular risk in patients with subclinical Cushing syndrome before and after surgery. (Abstract)

Evaluation of the cardiovascular risk in patients with subclinical Cushing syndrome before and after surgery. The widespread use of ultrasound, computerized tomography, and magnetic resonance imaging has led to an increase in the number of incidental adrenal masses identified. Asymptomatic incidentally discovered adrenal masses may indicate that subclinical Cushing syndrome (SCS) is not uncommon. We aimed to evaluate the cardiovascular risk of patients with SCS before and after surgery.An (...) autonomous cortisol-producing tumor was detected in 11 of 94 patients with adrenal incidentaloma between 1995 and 2005. Twenty-eight patients suffering from classical Cushing syndrome (CS) associated with unilateral adrenocortical adenoma, who were treated at our department in the same period, served as a control group. Cardiovascular risk factors such as blood pressure, body mass index, and lipid profile were evaluated before and 1 year after surgery.The frequency of hypertension (61% versus 63

3374. Carotid body tumor in a 13-year-old child: Case report and review of the literature. Full Text available with Trip Pro

Carotid body tumor in a 13-year-old child: Case report and review of the literature. Carotid body tumor (CBT), an extra-adrenal paraganglioma, represents an uncommon entity arising in chemoreceptor tissue located at the carotid bifurcation. Only a few cases have been reported in the literature in the pediatric age group less than 14 years of age, primarily as case reports. Surgical excision is advisable in almost all ages, however, in childhood, it is known to carry risks and difficulties due (...) to the smaller size of the involved anatomical structures. We report an unusual case of a large (50 x 43 x 30 mm) carotid paraganglioma of Shamblin type III in a 13-year-old female, living at high altitude until the age of 9 years. This cervical mass was present, but smaller in size, several years before admission. However, an intense hypoxic stimulus at high altitude for 2 months at the age of 13 years probably induced a fast growing period of the lesion. The tumor was removed en bloc with the involved

3375. Retroperitoneoscopic adrenalectomy: lateral versus dorsal approach. (Abstract)

Retroperitoneoscopic adrenalectomy: lateral versus dorsal approach. For tumours of the adrenal gland different surgical retroperitoneal approaches have been established, including the lateral and the dorsal approach. It is still unclear if the lateral or the dorsal approach should be preferred.A retrospective comparison between 21 patients who underwent retroperitoneoscopic adrenalectomy in lateral position (LRA) and 24 patients who underwent a retroperitoneoscopic adrenalectomy in dorsal (...) position (DRA).There were no significant differences with regard to the age, sex, tumour localisation, and the size of the tumour. The body-mass-index as well as the operation time was significantly higher of patients who underwent surgery in lateral position. Complications were comparable in both groups.The dorsal and the lateral retroperitoneal approach are ideal approaches for patients having had an intraabdominal surgery before. Due to the missing intraabdominal pressure the lateral approach

3376. Potential pitfalls in the diagnosis of phaeochromocytoma. (Abstract)

Potential pitfalls in the diagnosis of phaeochromocytoma. Six patients being evaluated for phaeochromocytoma had misleading investigative findings: all initially had raised urinary catecholamine levels, and five had adrenal masses on imaging studies. Adrenalectomy in these five patients revealed only one pathologically confirmed phaeochromocytoma. Tricyclic antidepressant use produced misleading elevations in urinary catecholamine levels in three patients. 24-hour urine studies should

-onset growth-hormone deficiency results in reduced muscle mass, increased fat mass and diminished quality of life, which are reversed by growth hormone replacement therapy. While trans-sphenoidal surgery remains first-line treatment for acromegaly, drug treatment has an important role in controlling residual growth-hormone excess and, in some circumstances, as first-line treatment. Dopamine-agonist therapy (cabergoline or bromocriptine) is the treatment of choice for micro- and macroprolactinomas (...) . In patients with suggestive clinical features, elevated 24-hour urine free cortisol level is usually sufficient to diagnose endogenous Cushing's syndrome; careful additional investigation is needed to determine whether the cause is Cushing's disease (pituitary adenoma secreting adrenocorticotropic hormone [ACTH]), ectopic ACTH secretion or adrenal disease. Heightened awareness is needed to detect the sometimes subtle symptoms and signs of pituitary disease

3379. Primary intraosseous paraganglioma of the sacrum: a case report. (Abstract)

Primary intraosseous paraganglioma of the sacrum: a case report. Paragangliomas are neuroendocrine tumors that most frequently arise in the adrenal medulla, carotid body, and glomus jugulare. However, they have been reported in many other sites throughout the body. Within the central nervous system, the overwhelming majority of paragangliomas arise intradurally in the area of the cauda equina. We report a case of a woman who presented with back pain and radiculopathy and was found to have (...) an intraosseous sacral mass on magnetic resonance imaging (MRI). Operative biopsy revealed that this lesion was a paraganglioma. Chest, abdomen, and pelvis computed tomography scans revealed no other tumors. This lesion was treated with limited resection, decompression, stabilization, and radiation therapy.To report a rare case of an intrasacral paraganglioma that presented with back pain and radiculopathy and was treated with intralesional decompression, stabilization, and radiation.Observational case

3380. Urinary cortisol and cortisol metabolite excretion in chronic fatigue syndrome. (Abstract)

Urinary cortisol and cortisol metabolite excretion in chronic fatigue syndrome. Reduced basal hypothalamic-pituitary-adrenal (HPA) axis output in chronic fatigue syndrome (CFS) has been inferred from low cortisol levels in blood, saliva, and urine in some studies. Because > 95% of cortisol is metabolized before excretion, we assessed cortisol output by assay of both cortisol metabolites and free cortisol in 24-hour urine collections and also investigated sex differences in these between CFS (...) and control groups.We calculated total urinary cortisol metabolites (TCM) and cortisol metabolite ratios from individual steroid data in 40 patients (20 males and 20 females) with CFS who were free of medication or comorbid psychiatric disorder likely to influence the HPA axis. Results were compared with those of 40 healthy volunteers (20 males and 20 females) well matched for age and body mass index. Data for free cortisol was obtained on 28 of the patients and 27 of the controls.The mean of TCM
