1/108. Recurrent hypoglycaemia in multiple myeloma: a case of munchausen syndrome by proxy in an elderly patient.A 73-year-old woman with multiple myeloma experienced four episodes of loss of consciousness, convulsions and profuse sweating whilst she was in the hospital. A thorough investigation in the department of medicine disclosed that with each attack, she had a serum glucose < 1.6 mM L-1, insulin level > 1400 pMol L-1 (N- < 150) and a normal level of serum c-peptide. Since she had no anti-insulin antibodies (which may rarely exist in multiple myeloma), a diagnosis of exogenous injection of insulin was made. A search for a possible perpetrator discovered that the patient had a daughter who was a surgical nurse and who was genuinely concerned whenever she was told that her mother was about to be discharged from the hospital. If she was the perpetrator in the present case, then it is possible that the motive for such an action was to postpone the mother's discharge from hospital. This case is an example of a 'factitious disease by proxy' in an elderly patient. The aim of the present report is to alert the medical personnel to the possibility that Munchausen's syndrome by proxy may also occur in the elderly.- - - - - - - - - - ranking = 1keywords = consciousness (Clic here for more details about this article) |
2/108. nesidioblastosis with hyperinsulinemic hypoglycemia in adults: report of two cases.We report herein the cases of two women, aged 34 years and 39 years, respectively, found to have hyperinsulinemic hypoglycemia after presenting with a history of episodes of temporary loss of consciousness, nausea, and fainting. Under the suspected diagnosis of insulinoma, localization procedures were carried out, but no tumor was found. In both patients, a definite gradient in insulin concentration was found in the pancreas by percutaneous transhepatic or intraoperative portal venous sampling, and a misdiagnosis of insulinoma of the pancreatic body was made. During exploratory laparotomy no tumor was palpable in the pancreas, and intraoperative ultrasonography showed no low echoic mass in the pancreas. A distal pancreatectomy was performed in both patients, and histopathological examination of the resected specimens revealed graded slight hyperplasia of the islet cells.- - - - - - - - - - ranking = 1keywords = consciousness (Clic here for more details about this article) |
3/108. 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 = 0.0088628193813242keywords = state (Clic here for more details about this article) |
4/108. hypoglycemia associated with high doses of sertraline and sulphonylurea compound in a noninsulin-dependent diabetes mellitus patient.Unlike other selective serotonin reuptake inhibitors (SSRIs), sertraline has linear pharmacokinetics so that increases in dose lead to proportional increases in drug concentration. The half-life of sertraline is about 26 h so that it reaches a steady state in one week, according to the product monograph. hypoglycemia associated with sertraline and coadministration of oral hypoglycemics belonging to the sulphonylurea derivatives has rarely been reported. A patient with schizoaffective disorder with non-insulin-dependent diabetes mellitus (NIDDM) treated with sertraline, risperidone and glyburide who developed hypoglycemia is presented. The article highlights that inhibition of P450 enzymes can be affected by several different factors. Interactions are possible whenever a patient concomitantly receives two drugs that bind to the same P450 system Greater inhibition was likely induced at doses higher than those recommended. This process was reversed within 10 days of discontinuing the sertraline. Good glycemic control followed discontinuation of psychotropic drugs and the oral hypoglycemic agent. knowledge of the individual P450 enzymes is important in the metabolism of individual drugs, together with an understanding of the patient's drug metabolizing ability. These factors may lead to more appropriate prescribing and further research into specific P450 enzymes responsible for metabolism of particular drugs, which remains unclear.- - - - - - - - - - ranking = 0.0088628193813242keywords = state (Clic here for more details about this article) |
5/108. Riding out a diabetic emergency.Acute complications of diabetes are like a runaway roller coaster. Diabetes or its treatment can rocket your patient's blood glucose level to dizzying heights or plunge it to life-threatening lows. hypoglycemia, the most common endocrine emergency, typically occurs in a known diabetic patient whose therapy with insulin or oral diabetes agents goes awry. At the opposite extreme, soaring blood glucose levels mark the acute conditions diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic nonketotic state (HHNS). These complications may send the patient to the emergency department (ED) before he even knows he has diabetes. In this article, I'll explain how these problems develop and spell out nursing measures to get your patient back on track.- - - - - - - - - - ranking = 0.0088628193813242keywords = state (Clic here for more details about this article) |
6/108. Hypoglycemic coma masquerading thyrotoxic storm.A 59-year-old woman was hospitalized in hypoglycemic coma. Although hypoglycemia was promptly reversed, she was in a somnolent, restless state with tachycardia, tremor, profuse sweating, and high body temperature. Thyrotoxic storm was highly suspected and vigorous antithyroid regimens gradually brought her up to normal mental and cardiovascular states in several days. However, profound generalized myopathy necessitated the maintenance with a respirator. One month later, an episode of angina pectoris was followed by generalized convulsion, coma, and death in a few days. neuroimaging study disclosed posterior leukoencephalopathy syndrome. This case is instructive in that hypoglycemic coma may masquerade the major symptomatology of thyrotoxic storm, and that profound myopathy and angiopathic or angiospastic processes of the brain and the heart may interfere with the outcome.- - - - - - - - - - ranking = 0.017725638762648keywords = state (Clic here for more details about this article) |
7/108. Importance of storing emergency serum samples for uncovering murder with insulin.A case of a previously healthy 48-year-old man murdered by exogenous insulin administration is reported. The patient was delivered unconscious to the emergency unit. Initially, treatment with hyperbaric oxygen was commenced because decompression sickness was suspected. However, the treatment was aborted as the patient was found to be hypoglycaemic (nadir serum glucose 0.3 mmol/l) and treatment and diagnostics of hypoglycaemia commenced. brain damage due to hypoglycaemia was severe, and the patient remained in a vegetative state for 2 months before he died of multiorgan failure. serum samples drawn at admittance were stored frozen, whereby it was possible to show retrospectively, that while the concentration of insulin in serum was high (75 mU/l, increasing further to over 240 mU/l in the next few hours) concentration of c-peptide was low (below detection limit of 0.1 nmol/l) at the hypoglycaemic stage. It was concluded that the patient had received exogenous insulin somehow, and the police was informed. Circumstantial evidence obtained during ensuing criminal investigation was considered by the court to prove the patient's wife (a nurse) guilty of murder. The availability of stored frozen serum samples drawn at the early stage of hospitalization helped to uncover the crime involved in our case.- - - - - - - - - - ranking = 0.59777234486526keywords = unconscious, state (Clic here for more details about this article) |
8/108. Haemorrhagic shock and encephalopathy syndrome: report of two cases with special reference to hypoglycaemia.Haemorrhagic shock and encephalopathy syndrome (HSES) is a devastating disorder affecting infants. So far no cases have been reported in switzerland. It is characterised by the abrupt onset of hyperpyrexia, shock, encephalopathy, diarrhoea, disseminated intravascular coagulation (DIC) and renal and hepatic failure in previously healthy infants. Severe hypoglycaemia has been repeatedly reported in association with HSES. However, the pathophysiology of the hypoglycaemia is not clear. We report on two infants (2 and 7 months old) with typical HSES, both of whom were presented with nonketotic hypoglycaemia. In the first case, plasma insulin was 23 pmol/l at the time of hypoglycaemia (0.1 mmol/l). In the second case, increased values for interleukin-6 (IL-6) (319 pg/ml) and IL-8 (1382 pg/ml) were found 24 hours after admission, whereas IL-1 and tumour necrosis factor-alpha (TNF-alpha) were not measurable. Alpha-1-antitrypsin was decreased (0.6 g/l). In hyperpyrexic, unconscious and shocked infants, HSES should be considered and hypoglycaemia should be specifically looked for. Hypoglycaemia is not caused by hyperinsulinism but may be secondary to the release of cytokines.- - - - - - - - - - ranking = 0.58890952548393keywords = unconscious (Clic here for more details about this article) |
9/108. 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 = 0.0088628193813242keywords = state (Clic here for more details about this article) |
10/108. 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 = 1keywords = consciousness (Clic here for more details about this article) |
