1/28. Bilateral basal ganglion haemorrhage in diabetic ketoacidotic coma: case report.We report bilateral oedema and haemorrhagic transformation in the basal ganglia of a 59-year old woman with severe diabetic ketoacidosis. Lack of cerebral vascular autoregulation, followed by blood-brain barrier disruption due to the so-called breakthrough mechanism is presumed to be the cause.- - - - - - - - - - ranking = 1keywords = ketoacidosis (Clic here for more details about this article) |
2/28. Central brain herniation secondary to juvenile diabetic ketoacidosis.We present the CT, MR, and autopsy findings of central brain herniation in a 9-year-old boy undergoing treatment for diabetic ketoacidosis (DKA). Severe cerebral edema resulting in central brain herniation is an uncommon complication of the treatment of DKA but carries with it high morbidity and mortality. Radiologic imaging and autopsy findings in this case revealed striking infarctions of central brain structures.- - - - - - - - - - ranking = 5keywords = ketoacidosis (Clic here for more details about this article) |
3/28. The care of students with insulin-treated diabetes mellitus living in university accommodation: scope for improvement?Concern has been expressed about the welfare of young adults with Type 1 diabetes mellitus who leave home to attend university or college for tertiary education. This has been highlighted by the local experience in Edinburgh of two male students with Type 1 diabetes, both of whom died from metabolic complications of diabetes during their first term at universities distant from their homes. One student died following the development of cerebral oedema secondary to diabetic ketoacidosis, which was probably precipitated by prolonged coma after an episode of severe hypoglycaemia. Another student, who was found 'dead in bed', had a history of previous severe hypoglycaemia. At a Fatal Accident Inquiry in Edinburgh, held following the death of the first student, recommendations were made to improve the care and personal safety of students with diabetes living in university accommodation. Despite the report being circulated to all Scottish universities, the second student died within three years of the inquiry. Further efforts to protect the welfare of students with Type 1 diabetes who are attending centres for tertiary education away from their home environment may require the more active participation by diabetes healthcare professionals.- - - - - - - - - - ranking = 1keywords = ketoacidosis (Clic here for more details about this article) |
4/28. serum S-100beta protein is a potential biochemical marker for cerebral oedema complicating severe diabetic ketoacidosis.CASE REPORT: A 39-year-old man with Type 1 diabetes mellitus was hospitalized with severe diabetic ketoacidosis (DKA). Sixteen hours after admission he suddenly deteriorated having a respiratory then cardiac arrest. A brain computed tomography scan performed 2 h after the respiratory arrest showed severe cerebral oedema. Serial serum samples were stored and analysed for S-100beta protein. The S-100beta protein concentration was initially normal (0.12 microg/l) then rose significantly before the onset of the respiratory arrest (8.5 h = 0.61 microg/l, 14.5 h = 0.9 microg/l, 18 h = 1.6 microg/l, 25.5 h = 3.1 microg/l, 34 h = 4.6 microg/l and44 h = 19.5 microg/l). CONCLUSIONS: In this case of DKA, serum S-100beta concentration rose coinciding with the onset of cerebral oedema, before it became clinically evident. Monitoring serum S-100beta may have a useful role in the management of DKA.- - - - - - - - - - ranking = 5keywords = ketoacidosis (Clic here for more details about this article) |
5/28. Cerebral venous thrombosis during diabetic ketoacidosis.Neurological deterioration during an episode of diabetic ketoacidosis is usually assumed to be caused by cerebral oedema. We present a case of cerebral venous sinus thrombosis presenting in a similar manner, also associated with severe iron deficiency anaemia. Computed tomography scanning provided the correct diagnosis and allowed institution of anticoagulation with improvement in neurological outcome. neuroimaging should always be performed in suspected cerebral oedema associated with diabetic ketoacidosis in order to exclude other pathologies.- - - - - - - - - - ranking = 6keywords = ketoacidosis (Clic here for more details about this article) |
6/28. hypopituitarism following cerebral oedema with diabetic ketoacidosis.Clinical evidence of cerebral oedema occurs in approximately 1% of diabetic ketoacidosis episodes. mortality from this serious complication is falling, but little is known of long term outcome. We describe hypopituitarism and executive dysfunction developing two years after cerebral oedema complicating diabetic ketoacidosis in a 12 year old with type 1 diabetes.- - - - - - - - - - ranking = 6keywords = ketoacidosis (Clic here for more details about this article) |
7/28. Extrapontine myelinolysis in a pediatric case of diabetic ketoacidosis and cerebral edema.Central pontine and extrapontine myelinolysis are characterized by symmetric demyelination following rapid shifts in serum osmolality, although in extrapontine myelinolysis, demyelination is confined to the supratentorial compartment. We present a case of extrapontine myelinolysis in a 17-year-old female that occurred in the setting of diabetic ketoacidosis, cerebral edema, mannitol therapy, and meningitis. The rate of correction of this patient's glucose and electrolyte levels was within well-accepted limits. Extrapontine myelinolysis is rare in pediatric patients: there are only 12 reports of extrapontine myelinolysis in children under age 20 years and no pediatric cases of extrapontine myelinolysis or central pontine myelinolysis associated with diabetic ketoacidosis. We review the published cases of extrapontine myelinolysis and examine the underlying etiologies and electrolyte disturbances that characterize these cases. This case expands the list of conditions in which extrapontine myelinolysis occurs to include pediatric patients with complicated diabetic ketoacidosis, emphasizing the importance of sudden osmolar shifts in the genesis of this disorder.- - - - - - - - - - ranking = 7keywords = ketoacidosis (Clic here for more details about this article) |
8/28. Hypothalamopituitary deficiency and precocious puberty following hyperhydration in diabetic ketoacidosis.We report on a 5-year-old child who survived an intracerebral crisis, following ketoacidosis-revealing diabetes (DKA), with visual impairment due to a vascular occipital lesion. Two and 4 months after the initial episode, a unique hypothalamopituitary disorder consisting in GH, ACTH, TSH deficiencies and central precocious puberty, was detected. Cranial magnetic resonance images showed no visible lesion in the hypothalamopituitary region. The most likely hypothesis is the ischemia of hypothalamopituitary and occipital regions following possible cerebral edema after hyperhydration. She survived with low visual acuteness and received a combined replacement therapy for the neuroendocrinological deficiencies. This case emphasizes that the rehydration at the initial period of DKA is critical, especially when risk factors for cerebral edema are present (young age, marked hyponatremia). The neuroendocrinological consequences of acute cerebral edema are rare, but physicians must be attentive in survivors of these accidents.- - - - - - - - - - ranking = 5keywords = ketoacidosis (Clic here for more details about this article) |
9/28. Childhood diabetes presenting with hyperosmolar dehydration but without ketoacidosis: a report of three cases.BACKGROUND: diabetic ketoacidosis (DKA) is a common mode of presentation of diabetes mellitus in children, accounting for 26% of new cases. Rarely, children with diabetes may develop other forms of metabolic decompensation associated with hyperglycaemia and hyperosmolality. Hyperglycaemia and hyperosmolality without ketoacidosis has high mortality in adults, although there is no data on mortality in children. case reports: We describe three children who presented to Birmingham Children's Hospital and were initially suspected to have DKA. Each child was severely hyperglycaemic and hyperosmolar but without significant ketosis or acidosis. In two of the three children, the hyperosmolar state was associated with the ingestion of large volumes of high calorie fluids preceding the presentation. These children were exquisitely sensitive to insulin and may be at a significantly higher risk of cerebral oedema in view of their hyperosmolar state. CONCLUSIONS: Hyperosmolar hyperglycaemia is a serious and rare complication at presentation of diabetes in children, and should be distinguished from DKA. These children are at an increased risk of cerebral oedema compared with DKA, and one should have a low threshold for suspicion of this complication.- - - - - - - - - - ranking = 6keywords = ketoacidosis (Clic here for more details about this article) |
10/28. hyperventilation in severe diabetic ketoacidosis.OBJECTIVE: To explore whether the carbon dioxide-bicarbonate (P(CO(2))-HCO(3)) buffering system in blood and cerebrospinal fluid (CSF) in diabetic ketoacidosis should influence the approach to ventilation in patients at risk of cerebral edema. DATA SOURCE: medline search, manual search of references in articles found in medline search, and use of historical literature from 1933 to 1967. DESIGN: A clinical vignette is used--a child with severe diabetic ketoacidosis who presented with profound hypocapnia and then deteriorated--as a basis for discussion of integrative metabolic and vascular physiology. STUDY SELECTION: Studies included reports in diabetic ketoacidosis where arterial and CSF acid-base data have been presented. Studies where simultaneous acid-base, ventilation, respiratory quotient, and cerebral blood flow data are available. DATA EXTRACTION AND SYNTHESIS: We revisit a hypothesis and, by reassessing data, put forward an argument based on the significance of low [HCO(3)](CSF) and rising Pa(CO(2))- hyperventilation in diabetic ketoacidosis and the limit in biology of survival; repair of severe diabetic ketoacidosis and Pa(CO(2))-and mechanical ventilation. CONCLUSION: The review highlights a potential problem with mechanical ventilation in severe diabetic ketoacidosis and suggests that the P(CO(2))--HCO(3) hypothesis is consistent with data on cerebral edema in diabetic ketoacidosis. It also indicates that the recommendation to avoid induced hyperventilation early in the course of intensive care may be counter to the logic of adaptive physiology.- - - - - - - - - - ranking = 11keywords = ketoacidosis (Clic here for more details about this article) |
