1/55. mucormycosis, a threatening opportunistic mycotic infection.mucormycosis is a rare and invasive mycotic opportunistic infection, occurring mostly in predisposed patients, mainly diabetics and immunocompromised individuals. The evolution of this fungal infection is frequently fatal unless aggressive treatment is started, or predisposing factors are handled. Our first patient was a known diabetic who had ketoacidotic coma at admission, complicated with pulmonary mucormycosis, and needed surgical resection followed by antimycotic therapy. The second patient did not survive his severe aplastic anemia (with neutropenia) and hemochromatosis (treated with desferrioxamine), complicated with a systemic rhizopus infection, despite treatment with amphotericin b and granulocyte-colony-stimulating factors.- - - - - - - - - - ranking = 1keywords = coma (Clic here for more details about this article) |
2/55. 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 = 4.0000593743503keywords = coma, brain (Clic here for more details about this article) |
3/55. Reversal of foetal hydrops and foetal tachyarrhythmia associated with maternal diabetic coma.Foetal hydrops is always a challenge for the clinician. We report a case of tachycardia associated with hydrops and hydramnios in a pregnancy complicated with diabetic coma at 28 weeks gestation. Normal foetal heart rate was recorded immediately after correction of maternal acidotic status and hydrops eventually disappeared. The woman was delivered at 32 weeks and the baby had an uncomplicated postnatal course. We hypothesise that maternal ketoacidosis has been the precipitating factor of tachycardia and congestive heart failure and that this case is conceptually similar to the "late death" phenomenon, reported in cases of poorly controlled maternal diabetes.- - - - - - - - - - ranking = 5.0000541731235keywords = coma, death (Clic here for more details about this article) |
4/55. lipids in the proximal tubules of the kidney in diabetic coma.Vacuolization of the renal tubular epithelial cells (the Armanni-Ebstein lesion) associated with diabetic hyperglycemia is usually regarded as an accumulation of glycogen. In a case of death of diabetic coma, the vacuoles were stained strongly for lipids. This observation may have both clinical and therapeutic consequences, and may increase our knowledge of the metabolism in diabetes.- - - - - - - - - - ranking = 5.0000541731235keywords = coma, death (Clic here for more details about this article) |
5/55. Marked hyperthermia as a manifestation of hypoglycemia in long-standing diabetes mellitus.Hyperthermia has recently been recognized as a manifestation of hypoglycemia. We describe two episodes of hypoglycemia associated with nausea, vomiting, chills, and impaired consciousness which were followed by marked hyperthermia. We suggest that the hyperthermia may result from excessive reaction to preceding hypothermia caused by the hypoglycemia. We would like to alert the clinician to the possibility of a previous, severe hypoglycemic episode in any diabetic patient with hyperthermia and coma.- - - - - - - - - - ranking = 1keywords = coma (Clic here for more details about this article) |

7/55. Possible functional regression of insulinoma with prolonged octreotide.A 75 year old woman was treated for over three years with the somatostatin analogue, octreotide for an insulinoma. She had presented in a hypoglycaemic coma. c-peptide and insulin concentrations were both raised and an area of increased vascularity within the pancreas was shown by angiography. No lesion was found at laparotomy and no resection was performed. After over three years of octreotide treatment it was withdrawn for a week. Her insulin and c-peptide concentrations were greatly reduced at this time and remained so.- - - - - - - - - - ranking = 1keywords = coma (Clic here for more details about this article) |

9/55. Nonketotic hyperglycemic hyperosmolar coma. Report of neurosurgical cases with a review of mechanisms and treatment.Seventy-eight critically ill patients who died while on the neurosurgical service were studied retrospectively to establish the prevalence of nonketotic hyperglycemic hyperosmolar coma (NHHC). All the patients had been comatose before death, and all underwent necropsy. Criteria for the diagnosis of NHHC included moderate-to-severe hyperglycemia with glucosuria, absence of significant acetonuria, hyperosmolarity with dehydration, and neurological dysfunction. This study revealed seven cases of unequivocal NHHC (9%), and six of hyperosmolarity but with incomplete records. Five of the seven confirmed cases of NHHC demonstrated no evidence of cerebral edema transtentorial herniation, or brain-stem damage, and showed central nervous system (CNS) lesions compatible with survival. Fatal complications of this syndrome, such as acute renal failure, terminal arrhythmias, and vascular accidents, both cerebral and systemic, were common in this series. The mechanism of coma in NHHC is believed related to shifts of free water from the cerebral extravascular space to the hypertonic intravascular space, with subsequent intracellular dehydration, accumulation of metabolic products of glucose, and brain shrinkage. It is uncertain whether injury to specific areas in the CNS is a predisposing factor to the development of NHHC. Factors documented to be significant in its development include nonspecific stress to primary illnesses, hyperosmolar tube feedings, dehydration, diabetes and mannitol, Dilantin, or steroid administration.- - - - - - - - - - ranking = 7.0001729218241keywords = coma, brain, death (Clic here for more details about this article) |
10/55. Repeated hypoglycemia and cognitive decline. A case report.OBJECTIVE: diabetes mellitus has a high incidence in general population and goes by high morbidity by specific micro vascular pathology in the retina, renal glomerul and peripheral nerves. In type 1 DM, intensive therapy can prevent or delay the development of long-term complications associated with DM but hypoglycaemia especially severe hypoglycaemia defined, as a low blood glucose resulting in stupor, seizure, or unconsciousness that precludes self-treatment is a serious threat. Hypoglycaemia that may preferentially harm neurons in the medial temporal region, specifically the hippocampus, is a potential danger for the brain cognitive function which several studies failed to detect any significant effects, whereas others indicated an influence on it. A young diabetic case presented here with severe cognitive defect. Great number of severe hypoglycaemic or hyperglycaemic attacks and convulsion episodes were described in his medical history. RESULTS and CONCLUSION: Neuroradiologic findings on CT and MRI, pointed that global cerebral atrophy that is incompatible with his age. Brain perfusion studies (SPECT, (99m)Tc-labeled HMPAO) also showed that there were severe perfusion defects at superior temporal region and less perfusion defects at gyrus cingulum in frontal region. These regions are related with memory processing. Severe cognitive defect in this patient seems to be closely related these changes and no another reason was found to explain except the repeated severe hypoglycaemic episodes.- - - - - - - - - - ranking = 5.9374350320055E-5keywords = brain (Clic here for more details about this article) |
