Abstract
BACKGROUND Surgical management of pheochromocytomas involves appropriate pre-operative alpha blockade. This process often results in multiple clinic visits, substantial delay in resection, and use of limited resources. We sought to evaluate the benefit of patient participation and doctor-patient telecommunication in pre-operative alpha blockade. METHODS A "study group" of patients, retrospectively collected, with pheochromocytoma requiring alpha-blockade therapy, during their initial clinic visit were educated on the use of a sphygmomanometer and the accurate detection of orthostatic blood pressure (BP). Subsequently, orthostatic evaluation and dose escalation were conducted through e-mail correspondence between the patient and the surgeon on a biweekly basis. This group of patients was compared with an historical "control group" consisting of 14 patients, whose preoperative treatment was titrated during clinic visits. RESULTS The two groups were similar in terms of operation performed (laparoscopic versus open), estimated blood loss, tumor size, and post-operative length of stay. Active patient participation in pre-operative alpha blockade therapy resulted in significantly fewer preoperative visits (mean 1.52 vs. 3.20 visits; P=0.02) and a significantly shorter time from initiation of blockade to resection (33 vs. 82 days; P=0.03). CONCLUSIONS Titration of alpha blockade therapy through patient and surgeon e-mail correspondence is efficacious and saves limited resources and time. This process eliminates unnecessary travel time and expenses for the patient. Due to the benefits of telemedicine for pheochromocytoma preoperative care, our method should be implemented in the routine surgical care of pheochromocytomas.

Abstract
Background Early diagnosis of pheochromocytoma and its proper management can lessen its mortality and morbidity. This case report describes a 24-year-old pregnant woman with an unusual presentation of pheochromocytoma. Case presentation An Iranian 24-year-old primigravid woman from Kordistan province was referred to our center with left flank pain at 37 weeks of gestation. She had a history of gestational diabetes mellitus since the 12th week of gestation which was managed by insulin administration. She also had a history of pulsatile bi-temporal headache for 2 years prior to her referral to us. She underwent complete abdominal and pelvic ultrasound imaging for her flank pain. This examination revealed a heterogeneous mass of 119 × 87 × 79 mm above her left kidney, highly suspicious of being an adrenal-originating tumor. Subsequently, we consulted an endocrinologist. She underwent abdominopelvic magnetic resonance imaging and her 24-hour urine metanephrine, normetanephrine, and vanillylmandelic acid were assessed. Finally, the diagnosis of pheochromocytoma was confirmed. She underwent a cesarean section and adrenal mass excision at the 40th week of gestation. This timely diagnosis resulted in her proper management and good maternal and neonatal treatment outcomes. Conclusions Our patient had pheochromocytoma during pregnancy. She had no complaints about hypertension before or during pregnancy until giving birth to her child; her only symptoms were a vague left flank pain, gestational diabetes, and headaches for the past 2 years. The unusual symptom of flank pain led to timely diagnosis and a good treatment outcome.

Abstract
Pheochromocytoma is a catecholamine-producing tumor. There are a very few reported cases of clinical pheochromocytoma. Here, we report a 27-year-old woman para 1 live 1 with chief complaint of headache, confusion, nausea, and vomiting 2 days after cesarean section. She was anxious and had palpitation. On physical examination, fever, tachycardia, tachypnea, high blood pressure, and right thyroid nodule were found. She was managed as pregnancy-induced hypertension at first. In laboratory data, epinephrine, norepinephrine, metanephrine, normetanephrine, and vanillylmandelic acid were increased in 24 h urine collection. An adrenal mass was detected in abdominal computed tomography. Regarding clinical and paraclinical findings, pheochromocytoma was diagnosed. The patient received medical treatment, but it was not effective; hence, she underwent adrenalectomy.

Abstract
Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, 123I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging. Before surgical removal of the tumors, the optimization of blood pressure, as well as intravascular volume, is an important measure to avoid and suppress perioperative adverse hemodynamic events. Preoperative preparation includes the use of alpha-adrenergic antagonists, beta-adrenergic antagonists with or without other antihypertensive agents, fluid therapy as well as insulin therapy for hyperglycemia if required. Due attention should be given to type and dose of alpha-receptor antagonists to be used and the duration of this therapy to achieve an optimal level of preoperative "alpha-blockade." Despite this preoperative preparation, many patients will have hypertensive crises intraoperatively which need to be promptly and carefully managed by the anesthesia team which requires intensive and advanced monitoring techniques. The most common complication after tumor removal is hypotension which may require fluid therapy and vasopressor support for a few hours. With advancement in surgical and anesthetic techniques, the incidence of severe morbidity and mortality associated with the surgery is low in high volume centers.

Abstract
Pheochromocytomas are rare endocrine tumors that can present insidiously and remain undiagnosed until death or onset of clear manifestations of catecholamine excess. They are often referred to as one of the 'great mimics' in medicine. These tumors can no longer be regarded as a uniform disease entity, but rather as a highly heterogeneous group of chromaffin cell neoplasms with different ages of onset, secretory profiles, locations, and potential for malignancy according to underlying genetic mutations. These aspects all have to be considered when the tumor is encountered, thereby enabling optimal management for the patient. Referral to a center of specialized expertise for the disease should be considered wherever possible. This is not only important for surgical management of patients, but also for post-surgical follow up and screening of disease in patients with a hereditary predisposition to the tumor. While preoperative management has changed little over the last 20 years, surgical procedures have evolved so that laparoscopic resection is the standard of care and partial adrenalectomy should be considered in all patients with a hereditary condition. Follow-up testing is essential and should be recommended and ensured on a yearly basis. Managing such patients must now also take into account possible underlying mutations and the appropriate selection of genes for testing according to disease presentation. Patients and family members with identified mutations then require an individualized approach to management. This includes consideration of distinct patterns of biochemical test results during screening and the appropriate choice of imaging studies for tumor localization according to the mutation and associated differences in predisposition to adrenal, extra-adrenal and metastatic disease.

Abstract
Adrenalectomy for pheochromocytoma is reported with a mortality close to zero in recent studies. The dogma of preoperative fluid and hypotensive drug administrations is widely applied in patients scheduled for pheochromocytoma removal and is assumed to have a beneficial effect on operative outcomes. This paradigm is only based on historical studies of non-standardized practices and criteria for efficacy, with no control group. Pre- and intraoperative hypovolemia have never been demonstrated in patients scheduled for pheochromocytoma removal. Recent improvements in outcome of patients undergoing adrenalectomy for pheochromocytoma could also be the result of improvement in surgical techniques and refinement in anesthetic practices. Whether better knowledge of the disease, efficiency of available intravenous short-acting vasoactive drugs, and careful intraoperative handling of the tumor make it possible to omit preoperative preparation in most patients scheduled for pheochromocytoma removal is presently questionable. We reviewed available literature in this respect.

Abstract
Paragangliomas, also known as extra-adrenal pheochromocytomas, arise from chromaffin cells within the autonomonic ganglia. Catecholamine secreting paragangliomas have been described in the mediastinum, but rarely invade the heart. This case describes the use of a novel bioabsorbable matrix that was used to replace a tumor invading the posterior left atrium.

Abstract
A 70-year-old patient who was undergoing treatment for diabetes mellitus and chronic hepatitis was admitted to our hospital for evaluation of a tumor in the left adrenal gland (50 x 45 mm) and renal failure. On the basis of the patient's increased serum concentrations of catecholamines and other metabolites and the results of positron emission tomography (PET), the patient was diagnosed with a pheochromocytoma; iodinated metaiodobenzylguanidine ([(131)I]MIBG) scintigraphy was insufficient to establish this diagnosis. Subsequently, he underwent surgery for tumor resection. Histological examination suggested the tumor to be a malignant pheochromocytoma. After left adrenalectomy was performed, the elevated catecholamine and metabolite concentrations and the blood pressure were restored to normal, and the patient's symptoms of severe headaches and vertigo reduced. Furthermore, his renal function improved (Cr 2.0-1.2 mg/dl). Our patient exhibited a rare condition of pheochromocytoma complicated by renal failure, which was successfully treated with laparoscopic surgery.

Abstract
This is a case report regarding a 45-year-old woman, who has been undergoing treatment for diabetes mellitus (DM) with chronic thyroiditis (euthyroid state). The patient was admitted to our hospital for the evaluation of a right adrenal tumor (50 x 45 mm) and episodic hypertension. She was diagnosed as having pheochromocytoma based on the increased catecholamine and metabolite concentrations and the result of iodine-131 metaiodobenzyl guanidine ((131)I-MIBG) scintigraphy. Subsequently, the right adrenal tumor was excised. Slowly, progressive type 1 DM (SPIDDM) was confirmed by seropositivity to anti-glutamic acid decarboxylase (1890 U/ml) and the clinical course. After right adrenalectomy, the elevated catecholamine and metabolite concentrations and blood pressure returned to normal, and the dosage of insulin injection was reduced. However, she still needed the insulin injection therapy to control her blood glucose level. This case exhibited an extremely rare combination of pheochromocytoma and SPIDDM with chronic thyroiditis. Although it is common for patients with pheochromocytoma to exhibit glucose intolerance, this case raises the suggestion that measuring the levels of the autoantibody for pancreatic islet cells should be considered if SPIDDM is suspected in a patient with pheochromocytoma.
