Four cases of asthma (one adult, three children) developing acute adrenal crisis after introduction of high-dose inhaled fluticasone proprionate are presented. The three children, aged 7-9 yrs, had been prescribed inhaled fluticasone, dosage 500-2,000 microg x day(-1) and duration 5 months-5 yrs. All presented with convulsions due to hypoglycaemia (blood glucose 1.3-1.8 mM). The fourth case was a male of 33 yrs with difficult-to-control asthma and had been taking fluticasone propionate 1,000-2,000 microg x day(-1) for 3 yrs. He presented with fatigue, lethargy, nausea and postural hypotension. Acute adrenal crisis in each case was confirmed by investigations which included measurement of acute phase cortisol levels, short and long Synacthen stimulation tests and glucagon stimulation tests. Other cases of hypthoalamic-pituitary-adrenal axis suppression were excluded.

The effects of insulin-induced hypoglycemic stupor and subsequent treatment with glucose on mouse cerebral cortical, cerebellar and brain stem levels of glucose, glycogen, ATP, phosphocreatine, glutamate, aspartate and GABA and on cerebral cortical and cerebellar levels of cyclic AMP and cyclic GMP have been measured. Hypoglycemia decreased glucose, glycogen and glutamate levels and had no effect on ATP levels in all three regions of brain. GABA levels were decreased only in cerebellum. Aspartate levels rose in cerebral cortex and brain stem, and creatine phosphate increased in cerebral cortex and cerebellum. In the hypoglycemic stuporous animals, cyclic GMP levels were elevated in cerebral cortex and depressed in cerebellum whereas cyclic AMP levels were unchanged from control values. Intravenous administration of 2.5-3.5 mmol/kg of glucose to the hypoglycemic stuporous animals produced recovery of near normal neurological function within 45 s. Only brain glucose and aspartate levels returned to normal prior to behavioral recovery. These results suggest that of the several substances examined in this study, only glucose and perhaps aspartate have important roles in the biochemical mechanisms producing neurological abnormalities in hypoglycemic animals.

A 22-day-old female infant was referred to our hospital due to unusual urine odor suspecting inborn error of metabolism. Physical examination revealed a stuporous and hypotonic infant with poor reflexes. Intravenous thiamine and high glucose along with appropriate protein were given under the suspicion of maple syrup urine disease (MSUD), which was confirmed by blood and cerebrospinal fluid amino acid assays, and urinary organic acid assay. Progressive neurological deterioration was observed despite the non-invasive treatment. So, we performed pump assisted continuous arteriovenous haemofiltration (CAVHF). Dramatic improvement in neurological function was observed hours after initiation of CAVHF, along with decrease in the level of isoleucine, leucine and valine. In our experience, CAVHF is a well-tolerated procedure for managing the acute phase of neonatal MSUD. Further study on indications, duration of treatment, and preventing complications is needed.

Hyperinsulinism, although rare, is the most common cause of persistent hyperinsulinaemic hypoglycaemia in infancy. Because of persistent hypoglycaemia, serious difficulties are encountered in the long term management of this condition. A male neonate, after an uncomplicated full-term pregnancy, had been admitted to another hospital with convulsions on the third post-natal day. Meningitis had been suspected at that time and treated with phenobarbital and he had been discharged from the hospital. At three-months old he was referred to our department for persistent convulsions and lethargy. His parents were of 1st degree consanguinity. His blood glucose level was found to be 24 mg/dl (1.33 mmol/L). Because of the dangerously high insulin level during hypoglycaemia (insulin/glucose > 0.3), the absence of ketonuria, and the need for a high dose of glucose infusion (> 15 mg/kg/min) to achieve normoglycaemia and a glycaemic response to glucagon despite the hypoglycaemia, a diagnosis of persistent hyperinsulinaemic hypoglycaemia of infancy was made. Since maximal doses of prednisone, glucagon, diazoxide, octreotide and high infusion of glucose were ineffective in achieving normoglycaemia, a subtotal (80%) pancreatectomy was done. Postoperatively intermittent hypoglycaemic episodes continued. These were controlled with low doses of octreotide. Histology revealed diffuse adenomatous hyperplasia (nesidoblastosis). The boy is now in the sixth post-operative month and developing normally.

Dumping syndrome is a sequel of gastric surgery in adults and Nissen fundoplication in children. The syndrome is characterized by various gastrointestinal symptoms as well as irritability, diaphoresis and lethargy. Shortly after a meal, symptoms are associated with hyperglycemia (early dumping), followed by late dumping symptoms associated with reactive hypoglycemia. Several therapeutic and dietary manipulations failed to control these symptoms in previous reports as well as in an infant we have followed after Nissen fundoplication. Acarbose, an alpha-glucosidase inhibitor, has been used sporadically in adults after gastric surgery, but only once in children. In most of these studies, the effect of acarbose (on reactive hypoglycemia) was evaluated over several hours postprandially or after oral glucose load. In our study, we recorded glucose dynamics by a continuous glucose monitor system over 2 to 3 days before and during acarbose treatment, while the patient was on a well-controlled diet. These measurements (720 before and 832 on therapy) suggested that both early and late dumping symptoms are causally related to the rate of glucose elevation and decline, rather than to glucose peak and nadir, respectively. Acarbose attenuated both postprandial glucose hyperglycemia and reactive hypoglycemia, which subsequently led to a significant reduction in dumping symptoms. In a follow-up of 14 months, acarbose was well tolerated and the frequency of dumping symptoms was remarkably reduced.

Hypoglycemia in the neonatal period is a well-recognized phenomenon, but many authors have commented upon the infrequent association of symptoms attributable to it. Six infants were seen who appeared normal at birth but who, between 24 and 72, hours of age, developed apnea, irritability, lethargy, muscular twitchings and convulsions. Blood sugar concentrations of 10 mg./100 ml. or less were found in each case. The mothers of four of the babies had toxemia of pregnancy. Three babies were premature. The hypoglycemia was self-limiting in all cases, and four of the babies recovered completely without sequelae. The other two showed evidence of permanent brain damage, but it is not known whether this was the cause of their symptoms or the result of the hypoglycemia. It is concluded that hypoglycemia may cause neurological symptoms in the newborn period and that treatment by glucose administration is necessary. Whether symptomless hypoglycemia requires treatment remains an open question.

A 14-year-old spayed female domestic shorthair cat was evaluated for weakness, lethargy, decreased appetite, diarrhea, weight loss, and seizures. On physical examination, the cat appeared disoriented and had an inconsistent menace response. An insulinoma was diagnosed on the basis of normal serum insulin activity in conjunction with profound hypoglycemia and histologic examination (with immunohistochemical staining for chromogranin A and insulin) of a pancreatic mass that was removed surgically. Blood glucose concentration was within reference limits after surgery. However, neurologic abnormalities persisted, and the cat was euthanatized. Chronic hypoglycemia, associated with insulinomas, can cause irreversible neuronal changes in cats; therefore, rapid diagnosis and treatment of hypoglycemic conditions are of critical importance.

A 5-year-old castrated male ferret began to exhibit signs of episodic lethargy, hindlimb weakness, and ataxia along with mild to moderate weight loss. Serial blood glucose measurements revealed persistent hypoglycemia. The animal was euthanized and a necropsy performed. Discrete pancreatic nodules were discovered and submitted for histopathologic analysis. One of the nodules was found to contain pancreatic islet cell tumors; other areas contained foci of islet cell and acinar hyperplasia. Pancreatic islet cell tumors, commonly referred to as insulinomas, are common tumors in ferrets and typically occur in middle-aged and older animals. These animals, when properly diagnosed, can be managed either medically or surgically or, often, by a combination of medical and surgical treatments, and their lives greatly extended.

A 64-year-old nondiabetic woman presented with spells of lightheadedness and diaphoresis associated with lethargy and hunger of 2 weeks' duration. Physical examination was unremarkable; however, her fasting plasma glucose was 66 mg/dl, with concurrent plasma insulin of 171 microIU/ml (normal, 5-27 microIU/ml). Her C-peptide and pro-insulin levels were elevated, with negative insulin antibody and negative urinary sulfonylurea levels. Abdominal computed tomographic scan demonstrated a 5 x 4-cm mass in the tail of the pancreas and many liver metastases. She underwent resection of the pancreatic mass, radiofrequency ablation, and cauterization of hepatic lesions. Histology confirmed pancreatic insulinoma. Ten months later, she was free of hypoglycemic symptoms, with normal plasma insulin C-peptide and significantly decreased proinsulin levels. Insulinomas are rare, predominantly benign tumors. Surgery is the only curative treatment. Octreotide can be used to control hormone secretion and tumor growth. Other treatments include hepatic embolization, radiotherapy, chemotherapy, and liver transplantation.

The explosive RDX (hexogen, cyclonite) is usually used for the production of C-4 explosive. The rare occurrence of accidental and intentional RDX intoxications has been reported during manufacturing process or in wartime. In this article, the authors report 5 cases of accidental oral RDX poisoning. On admission, observed signs and symptoms included repetitive generalized tonic-clonic convulsions, postictal coma, lethargy, confusion, hyperreflexia, postictal amnesia, nausea, vomiting, abdominal tenderness, sinusal tachycardia, dysrhythmia with frequent ventricular premature beats, generalized muscle spasms, and myoclonus. Leukocytosis, mild anemia, methemoglobinemia, elevated levels of blood glucose, serum aspartate transaminase, alanine transaminase, lactic dehydrogenase, creatine phosphokinase, amilase, hypokalemia, metabolic acidosis, proteinuria, glucosuria, and myoglobinuria were also noted. Plasma RDX concentrations were 268 to 969 ng/mL at 3 hours of ingestion. For management, supportive and symptomatic measures were taken. Whole-bowel irrigation might have been an effective therapeutic procedure due to probable slow gastrointestinal absorption of RDX. Three patients who developed severe metabolic acidosis underwent urgent hemodialysis. All patients were discharged 7 to 21 days after admission without any sequelae. Plasma RDX levels were strongly correlated with the clinical and laboratory manifestations. The available toxicological data on this rare accidental poisoning are reviewed in light of the literature.
