1/84. Hypoglycaemia induced by adrenal gland neoplasia (Anderson's syndrome) : report of a case.A patient with hypoglycaemia associated with an adrenal neoplasia (Anderson's syndrome) is reported. Endocrinological investigation showed increased secretion of cortisol and catecholamines as well as an increased urinary steroid excretion along with profound inhibition of both basal and stimulated insulin secretion. During IVGTT, Conard's coefficient was reduced. The hyperglycemic response to glucagon injection was blunted, suggesting that liver glycogen stores were decreased or unavailable.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/84. anorexia nervosa with severe liver dysfunction and subsequent critical complications.A twenty-year-old woman with anorexia nervosa (body mass index=11) suffered from severe liver dysfunction (aspartate aminotransferase 5,000 IU/l, alanine aminotransferase 3,980 IU/l, prothrombin time 32%), hypoglycemia (serum glucose 27 mg/dl), and pancreatic dysfunction (amylase 820 IU/l, lipase 558 IU/l). She fell into a depressive state with irritability, which was not improved by intravenous glucose. Despite treatment with plasmapheresis for the liver dysfunction, she subsequently developed pulmonary edema, acute renal failure, gastrointestinal bleeding, and disseminated intravascular coagulation. Hemodialysis, mechanical ventilation and drug therapy including prednisolone, prostaglandin E1, and branched-chain amino acid, improved her critical condition. In this case, malnutrition may have been the cause for the liver dysfunction and subsequent complications.- - - - - - - - - - ranking = 0.25keywords = gland (Clic here for more details about this article) |
3/84. Manifestations of hypercholesterolaemia, hypoglycaemia, erythrocytosis and hypercalcaemia in patients with hepatocellular carcinoma: report of two cases.BACKGROUND: Hypercholesterolaemia, hypoglycaemia, hypercalcaemia and erythrocytosis, are well-known paraneoplastic manifestations in patients with hepatocellular carcinoma (HCC). Hepatocellular carcinoma patients manifesting with two or three paraneoplastic manifestations have been previously reported. However, HCC patients presenting with four paraneoplastic syndromes have not been previously reported. methods AND RESULTS: This manuscript describes two HCC patients who manifested with hypercholesterolaemia, hypoglycaemia, hypercalcaemia and erythrocytosis during their clinical course. Erythrocytosis appeared early when HCC was diagnosed and declined to within normal range after optimal therapy for HCC. Hypercholesterolaemia manifested initially after the diagnosis in case 1, declined to within normal range after lobectomy and was re-elevated after tumour recurred. With disease progression, hypercalcaemia and hypoglycaemia occurred 1-3 months after diagnosis and the both patients subsequently died several days later. CONCLUSIONS: Similar features found in both patients were large tumour burden, high serum alpha-fetoprotein level and rapid downhill clinical course even with optimal therapy. The clinical significance of these paraneoplastic manifestations is discussed.- - - - - - - - - - ranking = 0.11486369614045keywords = lobe (Clic here for more details about this article) |
4/84. Acute adrenal insufficiency during pregnancy and puerperium: case report and literature review.Acute adrenal dysfunction during pregnancy is rare. Nevertheless, adrenal insufficiency can present as an adrenal crisis, and may be life threatening. There is a wide range of clinical symptoms and signs, and the differential diagnosis is challenging. A full adrenal and pituitary evaluation, both structural and hormonal, must be performed to reach the correct diagnosis, and appropriate treatment must not be delayed. A case is presented of acute adrenal insufficiency that occurred 24 hours after a cesarean delivery. The initial symptoms included hypoglycemic seizures and coma. The workup, both hormonal and structural, revealed isolated adrenocorticotrophic hormone deficiency. This considers this case and reviews the differential diagnosis, diagnostic workup, and the treatment of adrenal dysfunction in pregnancy and the puerperium, as well as the obstetric outcome in women suffering from this disorder. TARGET AUDIENCE: Obstetricians & Gynecologists, family physicians. learning OBJECTIVES: After completion of this article, the reader will be able to understand the various presentations of hypopituitarism, the various etiologies of this condition, and the appropriate work up and management of a patient with hypopituitarism.- - - - - - - - - - ranking = 112.3785972607keywords = pituitary (Clic here for more details about this article) |
5/84. Adrenal crisis presenting as hypoglycemic coma.An 18-month-old male infant presented with hypoglycemic coma and clinical signs of bronchopneumonia. He was suspected of suffering from septic shock. The patient progressed to irreversible multiple organ failure before the diagnosis of adrenal crisis was established. Plasma levels of ACTH and cortisol remained undetectable. renin and aldosterone were normal. An autopsy failed to demonstrate any adrenal gland cortical tissue. Immunohistochemical staining demonstrated the presence of all pituitary hormones except ACTH, establishing the diagnosis of isolated ACTH deficiency. intensive care clinicians should consider adrenal crisis in non-diabetic children with hypoglycemia and rapid circulatory deterioration.- - - - - - - - - - ranking = 112.6285972607keywords = pituitary, gland (Clic here for more details about this article) |
6/84. Isolated corticotropin deficiency in chronic alcoholism.Three patients who chronically abused alcohol were found to be hyponatraemic with normal plasma potassium. The first had been admitted with confusion and weight loss, the second with hypotension and sepsis, and the third with confusion and hypoglycaemia-induced seizures. All three patients had a subnormal cortisol response in the short synacthen test; however, the plasma cortisol after three days of tetracosactrin administration was greater than 550 nmol/L. Baseline corticotropin levels were less than 10 pg/mL in all three. No structural lesions of the hypothalamo-pituitary tract were found and there was no evidence of other endocrinopathies. Glucocorticoid replacement therapy led to the resolution of hyponatraemia and hypoglycaemia, where present, and to clinical improvement. The two surviving patients remained hypocortisolaemic in the long term, without recurrence of hyponatraemia or hypoglycaemia. The features of isolated corticotropin deficiency are easily confused with other effects of chronic alcohol abuse. In alcoholic patients with unexplained hyponatraemia, hypoglycaemia or haemodynamic instability, a short tetracosactrin test is advisable.- - - - - - - - - - ranking = 112.3785972607keywords = pituitary (Clic here for more details about this article) |
7/84. Fibrolamellar hepatocellular carcinoma in a Thai man who presented with hypoglycemia: case report and review of literature.We present a case of fibrolamellar hepatocellular carcinoma (FLHCC) in a 22 year old Thai man whose presenting symptom was hypoglycemic coma with right hemiparesis. The serum marker for hepatitis b virus (HBsAg) was positive and serum AFP was very high (over 100,000 IU/ml). The abdominal ultrasonography revealed a solitary heterogenic mass, size 5.5 x 6.5 cm in the right lobe. Chest X-ray showed multiple lung metastases. Ultrasound-guided needle liver biopsy was performed and typical histologic features of FLHCC in non-cirrhotic liver were diagnosed. The patient's comatose state and neurological deficits recovered rapidly after glucose administration. Unfortunately, the tumor mass could not be resected on account of far-advanced stage with metastases. Here, we also review of the literature concerning FLHCC in many aspects.- - - - - - - - - - ranking = 0.11486369614045keywords = lobe (Clic here for more details about this article) |
8/84. Primary malignant fibrous histiocytoma of the lung: IGF-II producing tumor induces fasting hypoglycemia.Augmented glucose utilisation or secretion of insulin-like-growth-factor II (IGF-II) are discussed as important pathogenetic factors in tumor-associated hypoglycemia (Doege-Potter Syndrome) with suppressed insulin and c-peptide levels. Primary malignant fibrous histiocytoma of the lung is an uncommon neoplasia and its association with hypoglycemia is rare and the causal relationship remains unclear. - We report a 57-year-old male with spontaneous hypoglycemia (1.67 mmol/l) due to a primary malignant fibrous histiocytoma of the lung, secreting IGF-II. Insulin (0.10 nmol/l; normal range 0.33-1.2) and c-peptide (3.0 mIU/l; 5-25) levels were suppressed in combination with low levels of growth hormone (<0.5 ng/ml; <7 ng/ml) and IGF-I (<66.0 ng/ml; 70-246). The elevated IGF-II level (787 ng/ml; 300-500) and decreased IGF-binding protein 3 (1.6 mg/l; 2-5) indicated a high free IGF-II activity. After surgery (resection of the right upper lobe), glucose (4.4 mmol/l), insulin (9.0 mIU/L) and c-peptide (0.84 nmol/l) levels returned to normal. serum IGF-I (289 ng/ml) and the IGF-I/IGF-II ratio (<0.08 preoperative vs. 0.41 postoperative; >0.20) increased to the normal reference range. - In conclusion, malignant fibrous histiocytoma (MFH) is rarely described presenting as tumor-induced hypoglycemia. Doege-Potter Syndrome in MFH seems to be related to tumor-associated IGF-II production.- - - - - - - - - - ranking = 0.11486369614045keywords = lobe (Clic here for more details about this article) |
9/84. Hyperinsulinemic hypoglycemia associated with possible hypopituitarism in a patient with acquired immunodeficiency syndrome.OBJECTIVE: To describe endocrine dysfunctions associated with human immunodeficiency virus (hiv) infection. methods: We present a case report, discuss the laboratory findings, and suggest potential contributing factors in this complex milieu. RESULTS: A 44-year-old man infected with hiv was admitted with loss of consciousness after a grand mal seizure and was found to have a prolonged course of hypoglycemia in conjunction with increased serum levels of insulin and C peptide. Iatrogenic hypoglycemia was excluded by laboratory evaluations. Hypothalamic-pituitary dysfunction was suspected because the serum growth hormone and cortisol concentrations during hypoglycemia were low. Radiologic evaluation of the brain revealed no structural abnormalities involving the hypothalamic-pituitary area. A normal cortisol response to adrenocorticotropic hormone stimulation (cosyntropin, 250 mg) was documented on two occasions. The cause of the severe hypoglycemic episode and the possible hypothalamic-pituitary-adrenal axis dysfunction in this patient is unknown. CONCLUSION: Despite the complexity of endocrine disorders in hiv-infected patients, the course of the disease in this patient underscores the possibility that some of the endocrinologic changes may be reversible.- - - - - - - - - - ranking = 337.13579178209keywords = pituitary (Clic here for more details about this article) |
10/84. Carcinoid syndrome, acromegaly, and hypoglycemia due to an insulin-secreting neuroendocrine tumor of the liver.We report a patient with a hepatic neuroendocrine tumor showing an extraordinary change of the tumor's humoral manifestations from a clinically documented extrapituitary acromegaly and a typical carcinoid syndrome toward a hyperinsulinemic hypoglycemia syndrome. At the primary manifestation of the tumor, an increased serum level of insulin-like growth factor i due to overproduction of GHRH and an increased urinary excretion of 5-hydroxyindoleacetic acid were found. The clinical manifestation of the GHRH excess was an arthralgia, which resolved completely after operative tumor debulking and normalization of insulin-like growth factor i and GHRH serum levels. The secretion of serotonin from the tumor resulted in a typical carcinoid syndrome including right-sided valvular heart disease. On the later course of the disease, the humoral manifestations of the tumor were supplemented by the secretion of insulin, leading to recurrent severe hyperinsulinemic hypoglycemia. The hepatic origin of hyperinsulinism was demonstrated by selective arterial calcium stimulation. Moreover, tumor cells revealed insulin and c-peptide immunoreactivity in the immunohistochemical analysis. The patient died 8 yr after the initial diagnosis of the tumor, and a carefully performed autopsy procedure confirmed the absence of any extrahepatic tumor manifestation.- - - - - - - - - - ranking = 112.3785972607keywords = pituitary (Clic here for more details about this article) |
