Abstract
BACKGROUND Pulmonary carcinoids are rare, low-grade malignant tumors characterized by neuroendocrine differentiation and relatively indolent clinical behavior. Most cases present as a slow-growing polypoidal mass in the major bronchi leading to hemoptysis and pulmonary infection due to blockage of the distal bronchi. Carcinoid syndrome is a paraneoplastic syndrome caused by the systemic release of vasoactive substances that presents in 5% of patients with neuroendocrine tumors. Due to such nonspecific presentation, most patients are misdiagnosed or diagnosed late and may receive several courses of antibiotics to treat recurrent pneumonia before the tumor is diagnosed. CASE SUMMARY We report the case of a 48-year-old male who presented with cough, dyspnea, a history of recurrent pneumonitis, and therapy-refractory ulcerative colitis that completely subsided after the resection of a pulmonary carcinoid. CONCLUSION We report and emphasize pulmonary carcinoid as a differential diagnosis in patients with nonresponding inflammatory bowel diseases and recurrent pneumonia.

Abstract
OBJECTIVES Carcinoid syndrome (CS) develops in approximately 20% of patients with neuroendocrine tumours (NET). This study described healthcare resource utilization and its associated costs among patients with NET and CS, using the French national health care data system. METHODS Patients were included if they had a hospital stay associated with the code E34.0 "CS" and at least one delivery of a somatostatin analogue (SSA) between 01/01/2012 and 31/12/2016. The end of the analysis was either 31/12/2017 or the date of death, whichever occurred first. Mean overall costs were described by item of expenditure and by periods. RESULTS 646 patients were included: 64yo, 55% men, 64% and 15% had NET from the small-intestine or lung, respectively. Among them, 309 patients were incident and 271 died during the study period. Mean overall cost per person per month (PPPM) was €2,892: €3,273 for the first year following diagnosis, €2,574 in "middle-years" and €5,039 within the year preceding death. The two most costly expenditure items were drugs (€1,695 PPPM) and hospital stays (€870 PPPM). CONCLUSION The first year following diagnosis and the year preceding death are the two periods representing the highest costs for CS care in France. Successful disease management may contribute to lower costs in the intermediate period.

Abstract
OBJECTIVES The aims of the study were to assess the effects of breakthrough carcinoid syndrome symptoms on well-being in neuroendocrine tumor (NET) patients insufficiently controlled on long-acting somatostatin analog (SSA) and to assess patient experience with treatment options, physician communication, and disease information sources. METHODS This study surveyed US NET patients from 2 online communities, experiencing at least one symptom, by utilizing a 64-item questionnaire. RESULTS One hundred patients participated: 73% female, 75% age 56 to 75 years, and 93% White. Primary tumor distribution was as follows: gastrointestinal NET (n = 55), pancreatic NET (n = 33), lung NET (n = 11), and other NET (n = 13). All patients were actively treated with one long-acting SSA and experiencing breakthrough symptoms: diarrhea, flushing, or other (13% experienced one, 30% two, 57% greater than two). More than one third of treated patients experienced carcinoid-related symptoms daily. Sixty percent of respondents reported not having short-acting "rescue" treatment available, impacting well-being though anxiety or depression (45%), trouble exercising (65%), sleeping (57%), employment (54%), and maintaining friendships (43%). CONCLUSIONS Breakthrough symptoms remain an unmet need, even in treated patients with NETs. Though still relying on physicians, NET patients are now also using the Internet. Improved awareness of optimal SSA use may improve syndrome control.

Abstract
PURPOSE Carcinoid heart disease (CHD) is a life-threatening complication of carcinoid syndrome (CS) characterised by tricuspid regurgitation (TR). However, there is an unmet need for earlier diagnosis of CHD. We cross-sectionally assessed the prevalence and potential predictive or diagnostic markers for CS and CHD in a contemporary cohort of patients with small intestinal neuroendocrine tumours (SI-NETs). METHODS Biochemical characteristics, hepatic tumour load, measures of arterial and endothelial function, atherosclerosis, and transthoracic echocardiography were analysed in a prospective cross-sectional setting. RESULTS Among the 65 patients studied, 29 (45%) had CS (CS+ ), and 3 (5%) CHD. CS+ was characterised by significantly higher hepatic tumour load, S-5-HIAA and fP-CgA, higher frequency of diarrhoea and flushing, and more frequent PRRT compared to CS- (for all, P < 0.05). Central systolic, central mean, and central end-systolic blood pressures were significantly higher in CS+ than in CS- (for all, P < 0.05). Subjects with grades 2-4 TR had higher hepatic tumour burden, fP-CgA, and S-5-HIAA compared to those with grades 0-1 TR, but measures of vascular function did not differ. fP-CgA (P = 0.017) and S-5-HIAA (P = 0.019) but not proBNP increased significantly according to the severity of TR. CONCLUSION Although CS is common, the prevalence of CHD was found to be lower in a contemporary cohort of SI-NET patients than previously anticipated. Measures of arterial or endothelial function or carotid atherosclerosis do not identify subjects with mild TR. Echocardiography remains the most sensitive means to diagnose CHD in CS patients with high tumour burden and elevated CgA and 5-HIAA.

Abstract
INTRODUCTION Carcinoid syndrome is the most frequent functional syndrome of neuroendocrine neoplasia. It is characterized by flushing, diarrhea, wheezing, hypotension, and exanthema and may cause carcinoid heart disease. METHODS We assessed clinical characteristics and prognosis of patients with carcinoid syndrome and carcinoid heart disease in 276 patients from 3 referral centers. RESULTS Carcinoid syndrome patients had a mean age of 57 years (range 21-84) and a normal BMI of 24.9 (SD 4.5; range 13.8-39.6). Most primaries were of small bowel or unknown primaries with distant metastasis in 94.6%. Flushing was the most frequent symptom in 74.3% of patients, followed by diarrhea in 68.8%, and wheezing in 40.9%. Pain was described by 45.3%, weakness by 23.5%, and weight loss of >10% in 6 months by 30.1% of patients. Carcinoid heart disease was diagnosed in 37.3% of patients (n = 104) by echocardiography and involved predominantly in the tricuspid valve. Combinations with other valve defects were common. Somatostatin analogs were taken by 80.4% of patients and 17% needed additional loperamide/opium tincture. Surgery and peptide receptor radiotherapy were most frequent treatments. The median survival of patients with carcinoid syndrome after diagnosis was 9 years. Prognosis was significantly impaired by male sex and diagnosis of carcinoid heart disease but surprisingly significantly increased by the presence of symptoms flushing and weakness. DISCUSSION/CONCLUSION Carcinoid syndrome is associated with extensive disease and primaries in small bowels or of unknown primary. Weight loss, weakness, and pain are frequent, and carcinoid heart disease is diagnosed in more than one-third of patients.

Abstract
PURPOSE To retrospectively evaluate the incidence of carcinoid crisis, other complications, and physiologic disturbances during percutaneous image-guided core needle biopsy of neuroendocrine tumors (NETs) in the lung and the liver. MATERIALS AND METHODS Between January 2010 and January 2020, 106 computed tomography (CT) or ultrasound (US)-guided core needle biopsies of lung and liver NETs were performed in 95 consecutive adult patients. The mean age was 64 ± 13 years, and 48% were female. The small bowel was the most common primary site (33%, 31/95), and 32 (34%) patients had pre-existing symptoms of carcinoid syndrome. The mean tumor size was 3.2 ± 2.6 cm, and mean number of passes was 3.4 ± 1.6. A 17/18-gauge needle was used in 91% (96/106) of the biopsies. Thirteen (12%) patients received either outpatient or prophylactic octreotide. RESULTS No patients experienced carcinoid crisis or needed octreotide, inotropes, vasopressors, or resuscitation. A single biopsy procedure (0.9%, 1/106) was complicated by bleeding that required angiographic hepatic artery embolization. Changes in pre-biopsy- versus post-biopsy systolic blood pressure and heart rate were -1.6 mm Hg (P = .390) and 0.6 beat/min (P = .431), respectively. Tumor functional status, overall tumor burden, and the elevation of neuroendocrine markers were not associated with intraprocedural physiologic disturbances. There were 4 minor complications (0.4%, 4/106) associated with the biopsy procedure that were not attributed to hormone excretion from tumor manipulation. CONCLUSIONS Percutaneous image-guided core biopsy of NETs is safe, with low complication rate and no definite carcinoid crisis in the current cohort.

Abstract
OBJECTIVE To develop a symptom-focused index to evaluate representative symptoms, treatment side effects, and emotional and functional well-being of patients with carcinoid syndrome (CS). METHODS The development of the Functional Assessment of Cancer Therapy-Carcinoid Syndrome Symptom Index (FACT-CSI) followed US Food and Drug Administration guidelines for the development of patient-reported outcome (PRO) measures and involved the following: (a) literature review; (b) interviews with 14 CS patients; (c) interviews with 9 clinicians; and (d) instrument development involving input from a range of PRO measure development and CS experts. The resulting draft instrument underwent cognitive interviews with 7 CS patients. RESULTS Forty-six CS sources were reviewed. Analysis of patient interviews produced 23 patient-reported symptoms. The most frequently endorsed physical symptoms were flushing, diarrhea, abdominal pain, fatigue, and food sensitivity/triggers. Seven priority CS emotional and functional themes were also identified by patients. Expert interviews revealed 12 unique priority symptoms - the most common being diarrhea, flushing, wheezing, edema, abdominal pain/cramping, fatigue, and 8 emotional and functional concerns. Through an iterative process of team and clinical collaborator meetings, data review, item reduction and measure revision, 24 items were selected for the draft symptom index representing symptoms, emotional concerns, global assessment of treatment side effects, and functional well-being. Cognitive interview results demonstrated strong content validity, including positive endorsement of item clarity (>86% across items), symptom relevance (>70% for most items), and overall measure content (86%). CONCLUSIONS The FACT-CSI is a content-relevant, symptom-focused index reflecting the highest priority and clinically relevant symptoms and concerns of people with CS.

Abstract
Carcinoid syndrome represents the most common functional syndrome that affects patients with neuroendocrine neoplasms. Its clinical presentation is really heterogeneous, ranging from mild and often misdiagnosed symptoms to severe manifestations, that significantly worsen the patient's quality of life, such as difficult-to-control diarrhoea and fibrotic complications. Serotonin pathway alteration plays a central role in the pathophysiology of carcinoid syndrome, accounting for most clinical manifestations and providing diagnostic tools. Serotonin pathway is complex, resulting in production of biologically active molecules such as serotonin and melatonin, as well as of different intermediate molecules and final metabolites. These activities require site- and tissue-specific catalytic enzymes. Variable expression and activities of these enzymes result in different clinical pictures, according to primary site of origin of the tumour. At the same time, the biochemical diagnosis of carcinoid syndrome could be difficult even in case of typical symptoms. Therefore, the accuracy of the diagnostic methods of assessment should be improved, also attenuating the impact of confounding factors and maybe considering new serotonin precursors or metabolites as diagnostic markers. Finally, the prognostic role of serotonin markers has been only evaluated for its metabolite 5-hydroxyindole acetic acid but, due to heterogeneous and biased study designs, no definitive conclusions have been achieved. The most recent progress is represented by the new therapeutic agent telotristat, an inhibitor of the enzyme tryptophan hydroxylase, which blocks the conversion of tryptophan in 5-hydroxy-tryptophan. The present review investigates the clinical significance of serotonin pathway in carcinoid syndrome, considering its role in the pathogenesis, diagnosis, prognosis and therapy.

Abstract
Neuroendocrine tumors (NETs) arise from enterochromaffin cells found in neuroendocrine tissues, with most occurring in the gastrointestinal tract. The global incidence of NETs has increased in the past 15 years, likely due to better diagnostic methods. Small-bowel NETs are frequently associated with carcinoid syndrome (CS). Carcinoid syndrome diarrhea occurs in 80% of CS patients and poses a substantial symptomatic and economic burden. Patients with CS diarrhea frequently suffer from diarrhea and flushing and report corresponding impairment in quality of life, requiring substantial changes in daily activities and lifestyle. Treatment paradigms range from surgical debulking to liver-directed therapies to treatment with somatostatin analogs, nonspecific anti-diarrheal agents, and a tryptophan hydroxylase inhibitor. Other causes of diarrhea, including steatorrhea, short bowel syndrome, and bile acid malabsorption, should be considered in NET patients with refractory diarrhea. More therapeutic options are needed for symptomatic management of patients with NETs, and better understanding of the pathophysiology can empower clinicians with improved patient care.

Abstract
PURPOSE OF REVIEW To review recent advances and controversies in all aspects of carcinoid-syndrome. RECENT FINDINGS Over the last few years there have been a number of advances in all aspects of carcinoid syndrome as well as new therapies. These include new studies on its epidemiology which demonstrate it is increasing in frequency; increasing insights into the pathogenesis of its various clinical manifestations and into its natural history: definition of prognostic factors; new methods to verify its presence; the development of new drugs to treat its various manifestations, both initially and in somatostatin-refractory cases; and an increased understanding of the pathogenesis, natural history and management of carcinoid heart disease. These advances have generated several controversies and these are also reviewed. SUMMARY There have been numerous advances in all aspects of the carcinoid-syndrome, which is the most common functional syndrome neuroendocrine tumors produce. These advances are leading to new approaches to the management of these patients and in some cases to new controversies.

Abstract
OBJECTIVE Flushing can be defined as a sensation of warmth accompanied by erythema that most commonly is seen on the face and which occurs in episodic attacks. Such a problem can be clinically problematic, since many conditions and drugs can be related to flushing, and while often there appears to be no underlying organic disease, it is important to exclude disorders since they may be life-threatening conditions. DESIGN AND METHODS We performed a search in MEDLINE using the terms 'flushing' in combination with 'carcinoid syndrome', 'pheochromocytoma', 'mastocytosis', 'menopausal hot flush' and 'treatment'. European and American guidelines relating to neuroendocrine tumours, mastocytosis and menopause were reviewed. RESULTS In this review, we discuss the main causes of flushing and propose an algorithm based on pathogenesis, which can be used to guide the clinical evaluation process. We also review recent significant developments in the assessment and treatment of the carcinoid syndrome and menopausal hot flushes, which should guide the clinical practice regarding this common but sometimes confusing condition. CONCLUSIONS When evaluating flushing, a precise systematic approach is needed to exclude potentially serious underlying causes, although despite this, the cause of the disorder is not always found. If symptoms are not progressive, the patient should be advised about its apparently benign nature in order to avoid unnecessary studies or initiating treatments of minimal benefit.

Abstract
AIM To discover unknown factors associated with carcinoid syndrome (CS) with the goal of earlier diagnosis of CS.
METHODS In this retrospective case-control study using United States administrative claims, patients (≥ 18 years) newly-diagnosed with gastrointestinal neuroendocrine tumors (GI NETs) without CS (controls) were exactly matched to patients with CS (cases) based on NET diagnosis date at a 3-to-1 ratio. Study index date was first CS diagnosis (controls: same distance from NET diagnosis as cases). The most observed conditions, excluding CS-associated symptoms/diagnoses, during the year before index date were assessed. Forward-stepwise logistic regression models were used to derive predictors, and were validated within another claims database.
RESULTS In the development database, 1004 patients with GI NETs were identified; 251 (25%) had CS and 753 (75%) were controls. In the validation database, 724 patients with GI NETs were identified; 181 (25%) had CS and 543 (75%) were controls. A total of 33 common diagnoses (excluding conditions already known to be associated with CS) in the development database were entered in forward step-wise logistic regression models. In the final, validated logistic regression model, three factors prior to CS diagnosis were found consistently associated with higher risks for CS, including liver disorder [odds ratio (95%CI): 3.38 (2.07-5.51)], enlargement of lymph nodes [2.13 (1.10-4.11)], and abdominal mass [3.79 (1.87-7.69)].
CONCLUSION GI NET patients with CS were 2-4 times as likely to have preexisting diagnoses (i.e., liver disorder, enlarged lymph nodes, abdominal mass) than non-CS patients.

Abstract
AIM: To examine healthcare resource utilization patterns and costs accrued by carcinoid syndrome (CS) patients with and without diarrhea.
METHODS: We conducted a retrospective cohort study using MarketScan® data from 1/1/2002-12/31/2012. Newly diagnosed CS patients had 1 medical claim for CS (ICD-9-CM code 259.2) plus either ≥ 1 additional claim for CS or for carcinoid tumors (ICD-9-CM 209.x), and had no evidence of CS for 1 year prior to index CS diagnosis, in commercially-insured patients < 65 years old. Patients were required to have continuous enrollment one year prior and after index date (first claim with CS diagnosis in the ID period). We identified patients with evidence of non-infectious diarrhea (ICD-9-CM codes 564.5 and 787.91) within one year from the index date. Overall and CS-related healthcare resource utilization and costs were compared between patients with and without non-infectious diarrhea during the one year period after the index date.
RESULTS: There were 2822 newly diagnosed CS patients; 534 (18.9%) had evidence of non-infectious diarrhea. Compared to patients without non-infectious diarrhea, non-infectious diarrhea patients more commonly had at ≥ 1 CS-related hospitalization (13.7% vs 7.2%), ≥ 1 CS-related ED visit (11.0% vs 4.4%), and CS-related office visits in one year (6.9 vs 4.1; all P < 0.001). After adjusting for demographics, region, number of chronic conditions and the Charlson Comorbidity Index, the proportions of patients with any and with CS-related hospitalizations were 9.7% and 6.8% higher, respectively, among non-infectious diarrhea patients compared to those with without non-infectious diarrhea (P < 0.001). Unadjusted costs were significantly higher among non-infectious diarrhea patients vs those without non-infectious diarrhea. The non-infectious diarrhea group was also more costly, with adjusted mean annual costs of $81610, compared to $51719 in the group without non-infectious diarrhea (P < 0.001).
CONCLUSION: Diarrhea is burdensome and costly in CS patients. Reduction of CS-related healthcare expenditures may be achievable through preventive treatment and appropriate management of diarrhea in CS.

Abstract
Although rosacea is one of the most common conditions treated by dermatologists, it also is one of the most misunderstood. It is a chronic disorder affecting the central parts of the face and is characterized by frequent flushing; persistent erythema (ie, lasting for at least 3 months); telangiectasia; and interspersed episodes of inflammation with swelling, papules, and pustules. Understanding the clinical variants and disease course of rosacea is important to differentiate this entity from other conditions that can mimic rosacea. Herein we present several mimickers of rosacea that physicians should consider when diagnosing this condition.

Abstract
The term red face is reserved for lesions located exclusively or very predominantly on the face that result from changes in cutaneous blood flow triggered by multiple different conditions. Facial erythema may not only present clinically as a distinct entity, but can also be a sign of other diseases. Patients with a red face challenge clinicians to consider a broad differential diagnosis. Diagnosis is based on date and mode of appearance, characteristics of the erythema, functional signs, and associated systemic manifestations. In most cases, the cause is a benign disease such as rosacea, contact dermatitis, photodermatosis, and climacterium, and a thorough history and physical examination is enough to make a diagnosis; facial erythema may also present as a symptom of drug allergies, cardiac disease, carcinoid syndrome, pheochromocytoma, mastocytosis, and anaphylaxis, as well as some rare causes such as medullary carcinoma of the thyroid, pancreatic cell tumor, and renal carcinoma where further laboratory, radiologic, or histopathologic studies are required. In this review, the mechanisms of flushing, its clinical differential diagnosis, and management of various conditions that cause flushing are discussed.

Abstract
Neuroendocrine tumors (NET) are solid potentially malignant tumors originated from the diffuse neuroendocrine system. They could origin in many organs, with highest prevalence in lungs, small intestine and rectum. Characteristics of NET are slow growth, non-specific clinical presentation causing diagnostic problems. Thus, in majority of patients diagnosis is established in the metastatic phase of the disease. Hopefully, there are new and very potent treatment options capable to successfully control the disease. Clinical presentation cause local tumor growth or para-neoplastic syndrome. Secretory active tumors produce peptides or hormones causing different clinical syndromes. In most cases NET cause carcinoid syndrome. It is often misinterpreted, because similar symptoms are present in more prevalent disorders. Symptoms are not specific and include flashing, diarrhea, abdominal pain, right heart disease, bronchoconstriction ... and to establish the right diagnosis medical doctor have to think about NET as a possibility. Thus, it is very important to recognize symptoms and signs of the carcinoid syndrome, and distinguish them from other gastrointestinal disorders. Early diagnosis and treatment have significant impact in control of the disease, and overall treatment results.

Abstract
Association of aggressive jejunal carcinoid tumors and other primary gastrointestinal neoplasms are rarely observed. We describe the case of a synchronous jejunal carcinoid tumor and two colorectal polyps in a 78-year old woman. Surgical intervention was performed for the colorectal tumors and the carcinoid was incidentally found. It was well differentiated but was accompanied by lymph node metastasis and peritoneal carcinomatosis. In this case, the prognosis was not depending by the colorectal tumors but the aggressive feature of jejunal carcinoid lead to patient's death.

Abstract
An 80-year-old male patient presented with abdominal pain, paroxysmal diaphoresis, diarrhoea and vomiting. CT scan revealed a small bowel endocrine carcinoma (or 'carcinoid' tumour), but the absence of hepatic disease. The lesion was excised 'en-bloc'. Intra-operatively, there was wide fluctuation in blood pressure associated with tumour manipulation, with hyper- and hypotension. Carcinoid syndrome usually occurs from gastrointestinal tumours when hepatic metastases occur, causing flushing, diarrhoea, bronchoconstriction and murmurs from cardiac valvular lesions. This patient did not have radiological evidence of hepatic metastasis, but the syndrome could still occur with midgut tumours via local invasion of the retroperitoneal circulation, or by action of substances other than serotonin that do not undergo hepatic metabolism.

Abstract
Carcinoid tumours are uncommon and carcinoid syndrome is likely to be encountered only occasionally during a clinical career outside the Neuro-endocrine and related specialties. Two cases of carcinoid syndrome are described in Royal Naval Reserve (RNR) personnel presenting simultaneously in the same unit. Both had long histories and, despite early contact with medical staff, had for some time been dismissed as having trivial complaints. Both have responded well to treatment, though neither has been able to have curative surgery. The current methods of diagnosis which allow much earlier identification and localisation of these tumours are discussed. We also review the management options now available which will control disease and allow the patient to pursue their chosen career, be it military or civil.

Abstract
Carcinoid tumors are malignancies originating from neuroendocrine cells, most commonly encountered in the gastrointestinal tract, in a rate of 64%, with the majority affecting the ileum. Certain genetic syndromes sometimes include carcinoid tumors in their phenotype. These malignancies may be rather asymptomatic, although occasionally they behave aggressively. They are typically diagnosed due to the effects of a locally advanced disease, or when producing symptoms because of hormone secretion (carcinoid syndrome). A better understanding of their molecular biology and behavior is demanded so that these tumors to be diagnosed precociously and managed effectively.

Abstract
The Endocrine Tumor Summit convened in December 2008 to address 6 statements prepared by panel members that reflect important questions in the treatment of acromegaly and carcinoid syndrome. Data pertinent to each of the statements were identified through review of pertinent literature by one of the 9-member panel, enabling a critical evaluation of the statements and the evidence supporting or refuting them. Three statements addressed the validity of serum growth hormone (GH) and insulin-like growth factor-I (IGF-I) concentrations as indicators or predictors of disease in acromegaly. Statements regarding the effects of preoperative somatostatin analog use on pituitary surgical outcomes, their effects on hormone and symptom control in carcinoid syndrome, and the efficacy of extended dosing intervals were reviewed. Panel opinions, based on the level of available scientific evidence, were polled. Finally, their views were compared with those of surveyed community-based endocrinologists and neurosurgeons.

Abstract
Paraneoplastic endocrine syndromes define a group of secondary signs and symptoms associated to a neoplasia, independently from the location of the primary tumor or its metastases. Paraneoplastic or ectopic endocrine syndromes usually result from aberrant hormone precursors or hormone-like substances by tumours. Knowledge of paraneoplastic endocrine complications is important both for the early diagnosis of neoplasia and the prognosis of the patient. In this review we discuss almost all reported paraneoplastic endocrine syndromes. We analyze their prevalence, etiology, laboratory diagnosis and treatment.

Abstract
INTRODUCTION We describe a previously healthy 40-year-old woman with Cushing's syndrome caused by adrenocorticotropic hormone (ACTH) secretion from metastatic carcinoid. CASE REPORT Over a 2-year period, the patient had multiple hospitalizations for uncontrolled hypertension, hyperglycemia, and hypokalemia. She had transient flushing, rashes, and a rapid weight gain. In addition, she developed anasarca and had a nontraumatic hip fracture 1 month before presentation. Subsequently, a hypertensive crisis resulted in admission to the intensive care unit and fine-needle aspiration of a liver lesion. DISCUSSION A diagnosis of metastatic carcinoid was established. She was transferred to our hospital for further evaluation and management. On arrival, she had the signs of Cushing's syndrome. Despite extensive evaluation, her primary carcinoid tumor was not localized. She was treated successfully with bilateral adrenalectomy and octreotide. CONCLUSION This case illustrates how early recognition of the signs and symptoms of excess ACTH is important for prompt and appropriate treatment.

Abstract
A case is reported of a woman who developed untreatable diarrhea after a prior biliopancreatic diversion (BPD), attributed to the malabsorptive component. Abdominal ultrasound incidentally found focal liver lesions. On fine needle aspiration biopsy, atypia was found, and these hepatic lesions were resected with free margins. The specimen showed liver metastases of an aggressive malignant neuroendocrine neoplasm. The primary site was subsequently identified to be in the pancreas. The physician and surgeon must realize that non-related diseases can develop after bariatric surgery, as in the general population.

Abstract
Carcinoid heart disease is a rare form of valvular heart disease. The management of these patients is complex, as the systemic malignant disease and the cardiac involvement have to be considered at the same time. Progress in the treatment of patients with carcinoid disease has resulted in improved symptom control and survival. Development and progression of carcinoid heart disease are associated with increased morbidity and mortality. In patients with severe cardiac involvement and well-controlled systemic disease, cardiac surgery has been recognized as the only effective treatment option. Valve replacement surgery may not only be beneficial in terms of symptom relief, but may also contribute to the improved survival observed over the past 2 decades in patients with carcinoid heart disease. Early diagnosis and early surgical treatment in appropriately selected patients may provide the best results. In this article, we review the current literature regarding the biology, diagnosis, treatment, and prognosis of carcinoid heart disease.

Abstract
A 66-year-old male with multiple liver tumors was diagnosed as having malignant carcinoid. The case exhibited carcinoid syndrome with wheezing and high urine 5-Hydroxy-Indole Acetic Acid and serum serotonin concentrations. A search for the primary lesion failed to detect tumors except those in the liver, leading to the diagnosis of primary hepatic carcinoid. Repeated transcatheter arterial chemoembolization with degradable starch microspheres decreased the tumors in size and improved the subjective symptoms. Transcatheter arterial chemoembolization with degradable starch microspheres is a useful treatment for unresectable malignant carcinoid of liver origin.

Abstract
Several circulating or urinary tumour markers can be used for the diagnosis and follow-up of functioning and clinically non-functioning neuroendocrine tumours of the pancreatic islet cells and intestinal tract. Among the specific tumour markers are serotonin and its metabolites--e.g. 5-hydroxyindoleacetic acid (5-HIAA)--in carcinoid tumours and the carcinoid syndrome, insulin and its precursors or breakdown products in insulinoma, and gastrin in gastrinoma. Plasma vasointestinal polypeptide (VIP) determinations have been used in the diagnosis of VIPoma, plasma glucagon for glucagonoma, and serum somatostatin for somatostatinoma. Among the tumour-non-specific markers are: chromogranins, neuron-specific enolase (NSE), alpha-subunits of the glycoprotein hormones, catecholamines, pancreatic polypeptide (PP), ghrelin and adrenomedullin.

Abstract
Neuroendocrine tumors (NET) of the gastrointestinal tract are rare and constitute 0.5-1% of all human malignancies. Based on their endocrine secretion, they are functional active or inactive. They are further classified into fore-, mid-, or hindgut tumors. The recently published WHO-classification grouped the tumors according to their tumor size, angioinvasion and Ki-67 index. NET are mainly diagnosed in an advanced tumor stadium because of the paucity of symptoms or when symptoms occur due to endocrine hypersecretion. NET are diagnosed serologically by their hormone secretion and by measuring Chromogranin A levels. They are further detected by CT, MRI or endoscopy including endoscopic ultrasound. Many NET have somatostatin receptors on their surface and can be diagnosed by somatostatin receptor scintigrafy with high sensitivity and specificity. Only by surgery NET can be cured. Because many tumors are diagnosed late, medical options are of utmost importance. Symptom control can be established by somatostatin analogues and interferon-ot. Diazoxid can further inhibit insulin secretion, proton pump inhibitors are the therapy of choice for acid hypersecretion in Zollinger-Ellison syndrome. Advanced neuroendocrine cancers can be treated with chemotherapy. Recently, radio receptor therapy with 90Y-DOTA Octreotid and 177Lu-DOTA Octreotate was established in advanced neuroendocrine cancers and is further evaluated in studies. Net of the gastrointestinal tract should be treated in a multidisciplinary approach with gastroenterologists, surgeons and experts in nuclear medicine. An overview about epidemiology, clinical features, diagnostic methods and therapy of NET of the gastrointestinal tract will is provided in this article.

Abstract
Gastro-intestinal carcinoids are slow growing tumors arising from enterochromaffin or Kulchitsky cells. Their clinical presentation depends on what combination of bioactive substances is secreted. Midgut carcinoid can present with the carcinoid syndrome in the presence of liver metastases. Its most typical clinical manifestations include cutaneous flushing and diarrhea. A nonspecific biochemical tumor marker for carcinoid tumors is serum chromogranin A and a specific marker for the carcinoid syndrome is the increased urinary excretion of 5-hydroxy indole acetic acid (5-HIAA). Localizing studies in carcinoid tumors/syndrome are: transabdominal ultrasonography (US), endoscopy, endoscopic US, videocapsule endoscopy, computerized tomography, magnetic resonance imaging, selective abdominal angiography, 111In-pentetreotide scintigraphy (and intraoperative radionuclide probe), 123I (131I)-metaiodobenzylguanidine (MIBG) scintigraphy, bone scintigraphy and 11C-5-HT positron emission tomography (PET). Therapies for carcinoid tumors/syndrome are: surgery, somatostatin analogs, interferon-alpha, radiotherapy, liver dearterialization, liver (chemo, or radio)-embolization, alcohol sclerotherapy of liver metastases, radiofrequency ablation of liver metastases, cryosurgery of liver metastases, occasionally liver transplantation, radiotherapy-coupled somatostatin analogs, 131I-MIBG and occasionally chemotherapy.

Abstract
Small bowel carcinoid usually presents with clinical symptoms and signs deriving from this endocrinological function and it rarely bleeds profusely. Below we present a case of a patient with intestinal bleeding. The bleeding tumor was finally diagnosed with the aid of wireless capsule endoscopy (CE) and histological examination showed a small bowel carcinoid.

Abstract
Endocrine tumors (ET) of the digestive tract (formerly called neuroendocrine tumors) are rare. They are classified into two principal types: gastrointestinal ET's (formerly called carcinoid tumors) which are the most common, and pancreaticoduodenal ET's. Functioning ET's secrete polypeptide hormones which cause characteristic hormonal syndromes. The management of ET is multidisciplinary. Poorly-differentiated ET's have a poor prognosis and are treated by chemotherapy. Surgical excision is the only curative treatment of well-differentiated ET's. The surgical goals are to: 1. prolong survival by resecting the primary tumor and any nodal or hepatic metastases, 2. control the symptoms related to hormonal secretion, 3. prevent or treat local complications. The most common sites of gastrointestinal ET's ( carcinoids) are the appendix and the rectum; these are often small (<1 cm), benign, and discovered fortuitously at the time of appendectomy or colonoscopic removal. Ileal ET's, even if small, are malignant, frequently multiple, and complicated in 30-50% of cases by bowel obstruction, mesenteric invasion, or bleeding. The carcinoid syndrome (consisting of abdominal pain, flushing, diarrhea, hypertension, bronchospasm, and right sided cardiac vegetations) is caused by the hypersecretion of serotonin into the systemic circulation; it occurs in 10% of cases and is usually associated with hepatic metastases. More than half of the cases of pancreatic ET are non-functional. They are usually malignant and of advanced stage at diagnosis presenting as a palpable or obstructing mass or as liver metastases. Insulinoma and gastrinoma (cause of the Zollinger-Ellison syndrome) are the most common functional ET's. 80% are sporadic; in these cases, tumor size, location, and malignant potential determine the type of resection which may vary from a simple enucleation to a formal pancreatectomy. In 10-20% of cases, pancreaticoduodenal ET presents in the setting of multiple endocrine neoplasia (NEM type I), an autosomal-dominant genetic disease with multifocal endocrine involvement of the pituitary, parathyroid, pancreas, and adrenal glands. For insulinoma with NEM-I, enucleation of lesions in the pancreatic head plus a caudal pancreatectomy is the most appropriate procedure. For gastrinoma with NEM-I, the benefit of surgical resection for tumors less than 2-3 cm in size is not clear. The lesions are frequently small, multiple, and widespread and recurrence is frequent after excision. The long-term prognosis is nevertheless fairly good. But the eventual development of liver metastases which are the most common cause of mortality still argues for an aggressive surgical approach in the early stages of the disease.

Abstract
BACKGROUND The incidence of carcinoid tumours is approximately 1.5 per 100 000 of the population. The malignant carcinoid syndrome, which is caused by circulating neuroendocrine mediators produced by the tumour, occurs in less than 10% of patients. Cutaneous involvement, although recognized in this rare syndrome, has rarely been reported. OBJECTIVES To examine a series of patients with the malignant carcinoid syndrome, to establish the prevalence and types of cutaneous involvement and to assess whether these could be used as indicators of disease activity, progression and prognosis. METHODS Patients with the malignant carcinoid syndrome who attended a multidisciplinary clinic for neuroendocrine tumours over a 23-month period between February 2001 and December 2002 were invited to participate in the study. This involved completion of a standard history proforma and a detailed cutaneous examination with findings recorded by clinical photography. RESULTS Twenty-five patients were enrolled. All but one had experienced flushing, three had rosacea, five had clinical features of pellagra and two had scleroderma. Flushing was generally an early manifestation of the syndrome, whereas both the pellagra and scleroderma tended to occur in more advanced disease. CONCLUSIONS This descriptive case series indicates that cutaneous features are not uncommon in the syndrome. They are readily diagnosed on clinical examination, and may be useful indicators of disease activity and prognosis.

Abstract
Gastrointestinal carcinoid tumors are rare neuroendocrine tumors arising from the embryologic primitive gut. Depending on the location in the gastrointestinal tract, these tumors may secrete a variety of hormonally active substances. However, many of these tumors are found incidentally, or the diagnosis is made postoperatively. Also, there is a significant incidence of multicentric carcinoid tumors and synchronous noncarcinoid malignancies in these patients. Treatment is usually based on the size of the tumor. Surgical resection remains the cornerstone of therapy. For advanced metastatic disease, somatostatin analog therapy and surgical debulking provide the best symptomatic relief and may improve survival. Recent studies have demonstrated a benefit from radiolabeled somatostatin analogs for carcinoid tumor localization. In contrast, radiolabeled somatostatin analogs have shown little therapeutic benefit. Future directions include somatostatin receptor profiling of carcinoid tumors, with somatostatin analog therapy targeting the specific receptors.

Abstract
A 35-year-old woman was scheduled for laparoscopic removal of an ovarian tumor. Intravenous metamizol was administered and when pneumoperitoneum was performed she developed severe hypotension and bronchospasm. Anaphylactic reaction was suspected, all drugs were suspended, and 2 doses of intravenous adrenalin (0.2 and 1 mg) were injected followed by continuous perfusion. Because response was slow and given the unknown origin of the tumor, the possibility of a carcinoid crisis was considered. When an intravenous bolus dose of octreotide was administered, pressure recovered, patient was extubated and could be transferred asymptomatic to the recovery ward. Tests later ruled out carcinoid syndrome, whereas tryptase levels in blood extracted during surgery and allergy tests confirmed an anaphylactic reaction to metamizol. Carcinoid crisis can be difficult to distinguish from anaphylactic reaction because the clinical pictures are similar. Anesthetic management of carcinoid crisis has been facilitated by administration of octreotide. Less is known about the use of octreotide to treat hypotension in patients with autonomic neuropathy based mainly on the drug's ability to produce splanchnic vasoconstriction. This is probably the reason why octreotide resolved our patient's shock in a context of systemic vasodilation caused by the anaphylactic reaction.

Abstract
Carcinoids are neuroendocrine tumours of the gut which may also be found in the bronchus, pancreatic islets and retroperitoneum. They probably arise from gastrointestinal or bronchopulmonary pluripotential stem cells. Carcinoid tumours derived from these cells are potentially malignant; the strength of the tendency for aggressive growth correlates with the site of origin, depth of local penetration and the size of the tumour. Carcinoids occur sporadically or result from specific hereditary tumour syndromes. Mutations and/or aberrant expression of specific genes induce and promote tumour growth. Clinical features include local symptoms due to angulation or obstruction and hepatomegaly due to liver metastases. The carcinoid syndrome commonly involves flushing, diarrhoea, bronchospasm and hypotension. Other distinct syndromes may be caused by tumour release of products that may also be used as biochemical markers in diagnosis and follow-up. Scanning using radiolabelled octreotide, an analogue of somatostatin, sensitively identifies occult primary and metastatic deposits. Localized carcinoid tumours should be resected. Some patients benefit from hepatic resection. Palliation of symptoms is best achieved with octreotide. Hepatic artery chemoembolization may produce long-acting palliation. Further genetic characterization of the different types and stages of carcinoid development as well as assessment of gene expression profiles may improve differential diagnosis, prognosis and treatment.
