Abstract
A 59-year-old woman unaware of having diabetes was transferred due to coma. Upon discovery at home, her consciousness on the Glasgow Coma Scale was E1V2M4, BP 95/84 mmHg, body temperature 34.7°C. On arrival at ER, height was 1.63 m, weight 97 kg, plasma glucose (PG) 1,897 mg/dL, HbA1c 13.6%, osmolality 421 mosm/kg, arterial pH 7.185, lactate 6.34 mmol/L, β-hydroxybutyrate 7.93 mmol/L. With saline and regular insulin infusion, PG was lowered to 1,440 mg/dL at 2 hours and then to 250 mg/dL by Day 3, and consciousness normalized by Day 5. On admission, serum immunoreactive insulin (IRI) was undetectable (<0.03 U/mL), C-peptide immunoreactivity (CPR) undetectable (<0.003 ng/mL), and anti-glutamic acid decarboxylase antibody negative. Following the above-described treatment, fasting PG was 186 mg/dL and CPR 1.94 ng/mL, respectively, on Day 14; 2-h post-breakfast PG 239 mg/dL and CPR 6.28 ng/mL, respectively, on Day 18. The patient discharged on Day 18 with 1,800 kcal diet, 32 U insulin glargine and 40 mg gliclazide. Fifteen months later at outpatient clinic, her HbA1c was 6.9% and 2-h post-breakfast PG 123 mg/dL and CPR 5.30 ng/dL with 750 mg metformin, 10 mg gliclazide and 18 U insulin glargine. Transient, but total cessation of insulin secretion was documented in a patient with type 2 diabetes under severe metabolic decompensation. Swift, sustained recovery of insulin release indicated that lack of insulin at the time of emergency was due to secretory failure, i.e., unresponsive exocytotic machinery or depletion of releasable insulin, rather than loss of beta cells.

Abstract
A 28-year-old man with type 1 diabetes mellitus was admitted for shock and coma due to diabetic ketoacidosis. Despite aggressive treatment and management of the patient's underlying clinical issues, the patient remained in a comatose state. Further investigations revealed an excess consumption of psychotropic agents; however, there was no evidence of an insulin overdose. Physicians should be aware that, in patients who are highly dependent upon insulin, an overdose of psychotropic agents can lead to hypoxic-ischemic brain injury.

Abstract
We report an uncommon case of an insulin-treated diabetic patient, presenting severe hypoglycemia, coma, marked sinus bradycardia and QT prolongation. Intravenous administration of glucose and atropine awaked the patient and increased heart rate but did not affect QT prolongation. Basal and exercise electrocardiogram excluded primary diseases associated with QT prolongation. Pathophysiologic aspects of electrocardiographic and clinical findings occurring in the hypoglycemic patients are briefly discussed.

Abstract
Fulminant type 1 diabetes mellitus (FT1DM) is characterized as remarkably abrupt onset and severe metabolic disorder. Prominent derangement of serum electrolytes was frequently observed, which could be associated with rhabdomyolysis. But the issue was not touched upon in most of the articles concerning FT1DM. Herein, we reported 2 cases. Since the clinical features of rhabdomyolysis vary, and creatine kinase levels are not routinely tested in young patients, the situation of rhabdomyolysis associated with FT1DM may be overlooked.

Abstract
Short-term mortality risk in young diabetic people is an indicator of quality of care. We assessed this in the Italian incident population-based registry of Turin. The study base included 1210 incident cases (n=677 aged 0-14 years and n=533 aged 15-29 years) with diabetes, onset period 1974-2000 in the Province of Turin, Italy. The relevant timescale for analysis was the time since the onset of diabetes to death, or till 31 December 2003. Standardized mortality ratio (SMR) for all-cause mortality was computed using the Italian population as a standard, by 5 years, age group, sex, and calendar period. Mean attained age of the incident cohort was 29.7 years (range 5.2-49.7 years). During a mean follow-up period of 15.8 years (range 2.0-29.9 years), there were 19 deaths in 15,967. Nine person-years of observation (n=9.5 expected deaths), giving an all-cause mortality rate of 1.19/1000 person-years (95% CI 0.76-1.87) and an SMR of 1.96 (1.25-3.08). In no cases did death occur at the onset of diabetes or in childhood. Out of 19 deaths, 9 were diabetes related (n=6 coma and n=3 end-stage renal disease). In Cox regression analysis, the hazard ratio (HR) was higher in adult-onset than in childhood-onset diabetes (HR=3.90, 95% CI 1.14-13.39), independently of calendar period and gender. (1) Children and young adults with type 1 diabetes experienced a two-fold higher short-term mortality risk than Italian people of similar age and sex and (2) the risk was higher in adult-onset than in childhood-onset diabetes. The quality of diabetes care should be improved to prevent early deaths.

Abstract
Hyperosmolar non-ketotic coma in diabetes is a life-threatening condition. We describe three patients, aged 59-67 years, who developed hyperosmolar coma during the first ten days after admission for stroke. Common to all three were normal plasma osmolality and slightly elevated plasma creatinine levels on admission, treatment with diuretics, parenteral dextrose administration before and low urinary glucose output during the coma. In the five days preceding the coma, total fluid deficits were 3.8, 6.5 and 9.4 1, respectively. In one patient the rate of glucose delivery had clearly exceeded utilization during adequate insulinization, in another a marked reduction in urinary glucose output preceded extreme hyperglycaemia and coma. Two of the three patients died, both from extensive thrombus formation in cerebral arteries and multiple emboli to the lungs. We conclude that enhanced endogenous glucose production and reduced renal clearance of glucose may contribute to precipitate hyperosmolar non-ketotic coma. A close monitoring of fluid and dextrose administration seems mandatory in diabetic stroke patients, in particular if renal function is impaired or if diuretics are given. Insulin treatment should be considered in all diabetic patients during the first days after a stroke.

Abstract
BACKGROUND Long-standing concern about the effects of type 1 diabetes on cognitive ability has increased with the use of therapies designed to bring glucose levels close to the nondiabetic range and the attendant increased risk of severe hypoglycemia. METHODS A total of 1144 patients with type 1 diabetes enrolled in the Diabetes Control and Complications Trial (DCCT) and its follow-up Epidemiology of Diabetes Interventions and Complications (EDIC) study were examined on entry to the DCCT (at mean age 27 years) and a mean of 18 years later with the same comprehensive battery of cognitive tests. Glycated hemoglobin levels were measured and the frequency of severe hypoglycemic events leading to coma or seizures was recorded during the follow-up period. We assessed the effects of original DCCT treatment-group assignment, mean glycated hemoglobin values, and frequency of hypoglycemic events on measures of cognitive ability, with adjustment for age at baseline, sex, years of education, length of follow-up, visual acuity, self-reported sensory loss due to peripheral neuropathy, and (to control for the effects of practice) the number of cognitive tests taken in the interval since the start of the DCCT. RESULTS Forty percent of the cohort reported having had at least one hypoglycemic coma or seizure. Neither frequency of severe hypoglycemia nor previous treatment-group assignment was associated with decline in any cognitive domain. Higher glycated hemoglobin values were associated with moderate declines in motor speed (P=0.001) and psychomotor efficiency (P<0.001), but no other cognitive domain was affected. CONCLUSIONS No evidence of substantial long-term declines in cognitive function was found in a large group of patients with type 1 diabetes who were carefully followed for an average of 18 years, despite relatively high rates of recurrent severe hypoglycemia.

Abstract
INTRODUCTION Wolfram syndrome is a genetic disease with recessive autosomic transmission, associating early-onset diabetes mellitus and bilateral optical atrophy. CASE REPORT We report the case of a 47-year-old patient for whom we diagnosed a Wolfram syndrome in view of a late neurological syndrome in association with ataxia and bilateral horizontal nystagmus. The brain resonance magnetic imaging revealed a major atrophy of the brainstem and cerebellum. CONCLUSION Wolfram syndrome is a rare pathology, with fatal consequences before the age of 50. The association of diabetes mellitus and optical atrophy, especially when there are other symptoms (ataxia, deafness, diabetes insipidus, neuropsychiatric manifestations or urinary tract disorders) should lead to this diagnosis and to carry out a genetic confirmation.

Abstract
A 45-year-old female diabetes-mellitus patient on peritoneal dialysis was admitted because of vertigo. During her stay in hospital she developed a comatose condition with abnormal head posture and deviation ofthe eyes to the left. Capillary blood from the fingertip showed a glucose value of 15.4 mmol/l. However, the automatically obtained glucose value delivered with a blood-gas analysis was found to be 1.2 mmol/l. The neurological state of the patient normalised fully after intravenous glucose administration. The glucose values were falsely elevated because the patient used a peritoneal dialysis fluid at night which contained icodextrin as an osmotic agent. Metabolites of icodextrin can influence blood-glucose measurements taken using analyzers that depend on the enzyme glucose dehydrogenase. To prevent potentially life-threatening situations, the use of an adequate glucose meter is of paramount importance.

One patient, with diffuse cortical lesions, had a poor outcome, but the other, with transient white matter abnormalities, made a complete recovery. The distinctive patterns of DW MR imaging abnormalities in hypoglycemic patients should be recognized and may be a predictor of clinical outcome.

Abstract
We present a case of rapid onset of glycogen storage hepatomegaly, caused by a massive dose of long-acting insulin and large doses of glucose, in a type-2 diabetic patient. A 41-year-old man was admitted to our hospital because of hypoglycemia and unconsciousness following subcutaneous administration of 180 units of insulin glargine in a suicide attempt. Despite continuous hypercaloric infusion with additional intravenous glucose injections, hypoglycemia persisted for 36 hours. Although the hepatic function was normal and no hepatomegaly was detected on admission, the liver function tests became abnormal and hepatomegaly was detected on hospitalization day 3. Plain abdominal computed tomography (CT) scanning confirmed liver enlargement, with hepatic CT attenuation markedly elevated at 83.7 HU. Liver biopsy revealed hepatocytic glycogen deposition with edematous degeneration. Based on these findings, the diagnosis was made as rapid onset glycogen storage hepatomegaly caused by administration of a massive dose of long-acting insulin and supplementation with large doses of glucose. With improved glycemic control, the liver function improved, the CT findings of hepatomegaly improved, and the hepatic CT attenuation decreased. Repeat liver biopsy also confirmed almost complete disappearance of glycogen deposits. When hepatic dysfunction or hepatomegaly is detected during treatment with insulin, the possibility of hepatic glycogen deposition should be considered. CT scanning and liver biopsy were useful in diagnosing this case.

Abstract
The hypoglycaemic coma is a severe complication for type 1 diabetic patients. Rarely fatal it may be associated with various paroxysmal accidents, potentially harmful, especially during driving. Hypoglycaemia certainly alters the quality of life because it markedly increases the anxiety of both the patient and his/her family. It is considered as a major limiting factor in the glycaemic management of type 1 diabetic patients. Being the consequence of numerous causal factors, hypoglycaemic coma is not always easy to prevent and may occur as a paroxysmal phenomenon, sometimes without obvious contributing circumstances. After having defined the various hypoglycaemic thresholds, we will analyse the pathophysiology of insulin-induced hypoglycaemia and of its hormonal counterregulation, and we will describe the hypoglycaemia unawareness phenomenon. These elements should help to better understand why a hypoglycaemic coma may suddenly occur in a diabetic patient. Some advices will also be given to reduce the risk of such a paroxysmal complication in patients with type 1 diabetes.

Abstract
This review describes the current guidelines of German diabetes association for the management of diabetic coma, both of diabetic ketoacidosis and hyperosmolal coma. The outline focuses on emergency treatment and the management on the intensive care unit, in particular, volume and insulin therapy, and potassium replacement. The delineation of the concept of low insulin therapy is emphasized to avoid the incidence of disequilibrium syndrome. Also, the indications for bicarbonate therapy in diabetic ketoacidosis are critically discussed, as well as phosphate and magnesium replacement. With today's therapeutic possibilities the therapeutic goal, i.e. a low mortality, may be achieved, dependent on the underlying illness.

Abstract
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.

Abstract
OBJECTIVE Although acute complications of diabetes account for approximately 3% of all emergency calls, clinically relevant indicators of structural and process quality in the management of diabetic emergencies have not yet been studied. The purpose of this investigation was, therefore, to collect representative data on these indicators for the whole of Germany. METHODS Standardized questionnaires comprising 20 items were sent to all 312 emergency medical services in Germany. Apart from demographic data, information was obtained about the diagnostic materials and drugs carried by the ambulances, methods of blood glucose measurement, the level of qualification of the emergency teams, the frequency of diabetic emergencies, and the need for further training. RESULTS The return rate of the questionnaires was 55%, corresponding to 172 emergency medical service districts serving a total population of 45.3 million. The data revealed deficits with regard to structural and process quality. Thus, only 6% of ambulances carried glucagon and only 11% ketone test strips. In 57% capillary blood was used for glucose determination, in 17% visually read test strips were still used. While in some districts hospital admission after hypoglycaemic episodes was mandatory even for patients well educated about their diabetes, in other districts multimorbid patients on oral antidiabetics were sometimes only treated at the emergency scene. Emergency medical technicians increasingly carried out both the diagnosis and treatment of diabetic emergencies. CONCLUSIONS The structural and process quality of the management of diabetic emergencies in Germany is in need of improvement. The most important factor is continuing education of the entire emergency team.

Abstract
Diabetes can affect the nervous system in several ways. Of all the neurological complications of diabetes, peripheral neuropathy is by far the commonest and has been extensively studied. The involvement of central nervous system can be in several forms. The underlying damage may be due to involvement of the large and small cerebral blood vessels as also due to metabolic derangement caused by prolonged hypoglycemia, anoxia or ketoacidosis. The neurological emergencies that occur in diabetes can be: 1) atherothrombotic and lacunar strokes; 2) convulsive disorder in the setting of both hypo and hyperglycemia; 3) coma; 4) cranial neuropathies; and 5) acute proximal muscle weakness. In patients with diabetes, atherothrombotic stroke is associated with poor outcome. Hyperglycemia at the time of stroke is an important risk factor for an adverse outcome than chronic stable diabetic state. Proper management of diabetes in these acute situations is crucial for a better outcome of the underlying disease process.

Abstract
Hypoglycaemia is a common side effect of insulin therapy in type 1 diabetes. In patients with type 2 diabetes treated with blood-glucose lowering agents of the sulphonylurea group, hypoglycaemia is less frequent than in insulin-treated patients. In most patients strict metabolic control increases the risk of hypoglycaemia, but this risk may be reduced if patients are offered individualised insulin treatment in combination with active support and education. Previously experienced hypoglycaemic episodes and lack of endogenous insulin production are risk factors for repeated episodes. Patients with longstanding diabetes and loss of warning symptoms have increased risk of severe hypoglycaemic episodes, which may lead to loss of consciousness or convulsions. Driving performance is significantly disrupted at relatively mild hypoglycaemia, and persons with diabetes should not start driving when their blood glucose is in the 4-5 mmol/l range without prophylactic treatment. They ought to have carbohydrate-rich snacks easily available in the car and should stop driving if they feel hypoglycaemic. Repeated episodes of severe hypoglycaemia seem to be associated with cognitive dysfunction. When deciding the targets of blood-glucose lowering therapy, the risk of severe hypoglycaemia must be weighed against the beneficial effects of good metabolic control.

Abstract
A 66-year-old woman with a 7-year history of Parkinsons' disease was admitted to our hospital because of a high fever and disturbance of consciousness. She had been treated with levodopa/benserazide hydrochloride and trihexyphenidyl hydrochloride until admission. On admission, the patient was comatose, her temperature was 40.5 degrees C, her blood pressure was 54/-mmHg, and her pulse rate was 130 beats/min. Laboratory tests showed leukocytosis, a high level of creatine kinase in serum and evidence of hyperosmolar non-ketotic diabetic coma (blood glucose, 1,080 mg/dl) and of disseminated intravascular coagulation (DIC). A continuous insulin infusion, antibiotics, nafamostat mesilate, and urinastatin were given, after which the DIC, hyperglycemia, and the level of consciousness were improved. However, levels of creatine kinase, myoglobin, transaminase, and amylase in serum continued to increase, and multiple organ failure was suspected. Furthermore, she became less responsive, diaphoretic, and tremulous; fever and mild rigidity developed. The peak creatine kinase and myoglobin were 11,095 U/l and 12,520 ng/ml, respectively. A diagnosis of malignant syndrome was made, and treatment with levodopa/carbidopa and dantrolene was begun. Within several days, the clinical and laboratory findings improved. We report here a rare case of malignant syndrome associated with DIC followed by diabetic coma in an elderly patient with Parkinsons' disease during L-dopa therapy. Timely diagnosis and treatment of malignant syndrome are important in the management of elderly patients with Parkinsons' disease, because DIC and multiple organ failure may occur in the early stages of malignant syndrome.

Abstract
BACKGROUND In France, 48% of children with insulin-dependent diabetes mellitus (IDDM) are seen for the first time at the stage of keto-acidosis (DKA), a figure far higher than in other countries. The four consecutive cases reported in this paper suggest that severity at presentation is directly related to the delay of diagnosis. CASE REPORTS All children, aged 6 to 11, presented with severe clinical and metabolic conditions: coma, hemodynamic failure, severe dehydration and acidosis (pH = 6.86 to 7.06). However, clinical symptoms were a present from 2 to 4 months, parents did not worry about them. Family practitioners visited 2-21 days before admission failed to immediately make the diagnosis of IDDM. True DKA was however present in all cases 48 hours prior to admission. CONCLUSIONS Earlier diagnosis of IDDM in children is necessary to reduce morbidity and mortality of DKA. General practitioners, pediatricians and emergency care practitioners must be made fully aware to consider diabetes in children and to use more extensively glucose-tests based on urine and blood strips.

Abstract
Hyperglycemia and its vascular complications affect the entire nervous system, contributing to increased morbidity and mortality. Chronic hyperglycemia is not only a known and major risk factor for cerebral vascular diseases but also the presence of hyperglycemia at the time of a cerebrovascular event may adversely influence the outcome. It also affects the treatment of some neurodegenerative disorders, and there are suggestions that diabetes may in fact suffer from a "chronic diabetic encephalopathy." Its varied effects on the peripheral nervous system result in several forms of diabetic neuropathies, the exact pathogenesis of which is still obscure. There is, however, some new information that may link metabolic and vascular hypotheses.

Abstract
One of the hallmarks of diabetes mellitus is its propensity to cause neurological complications. Diabetes is an independent risk factor of stroke. Diabetic neuropathy represents the most common type of peripheral neuropathy in our country. Improved glucose control can improve nerve function and restoration of the euglycemic state appears to stop the progression of the neuropathy. Treatment strategy of painful neuropathy with tricyclic antidepressant, anticonvulsant, anesthesia agents and topical capsaicin is discussed.

Abstract
A 58-year-old woman was admitted to our hospital for impaired consciousness, hyperglycemia and bitemporal hemianopsia. She was diagnosed as having NIDDM one year ago and was treated with diet and glibenclamide (1.25 mg/day) for 6 months. However, she stopped her medical treatment one month ago and then polydipsia and general fatigue were manifested. She was admitted to a hospital five days ago at which time hyperglycemia (405 mg/dl) and anemia (Hb8.0g/dl) were detected. She was transferred to our hospital for control of blood glucose and further examination of bitemporal hemianopsia. She showed typical acromegalic features including enlargement of the nose, lips and tongue, increased heel pad and acral growth. Conscious disturbance was cured by the infusion of saline and the administration of insulin. Endoscopy revealed an active gastric ulcer (A1). Endocrine data disclosed increased GH levels in plasma and urine, whereas plasma IGF-1 levels were low. Plasma GH paradoxically increased following the administration of TRH. A water deprivation test showed an impaired increase in urinary osmolarity, indicating partial central diabetes insipidus (DI). MRI with Gd-contrast revealed a macroadenoma which progressed toward suprasella. She was diagnosed as having acromegaly, partial DI and probable hyperosmolar hyperglycemic nonketotic diabetic pre-coma. Polyuria (5-101/day) due to partial DI was controlled by the administration of DDAVP (10 micrograms/day). The constant subcutaneous administration of octreotide (240 micrograms/day) resulted in normal plasma GH levels and a marked shrinkage of the pituitary tumor. The pituitary tumor was finally removed by the transsphenoidal approach following treatment with octreotide for 4 months. HE staining of the pituitary tumor showed atrophic and acidophilic cells surrounded by hyaloid connective tissue. After the surgery, plasma GH levels were normalized and complications were cured. In conclusion, this is a very rare case of acromegaly associated with diabetic pre-coma and partial DI, and effectively treated with constant subcutaneous infusion of octreotide.

Abstract
We observed two cases of severe diabetic ketoacidosis with coma and shock. In one case, coma was present at admission and in the second occurred within 15 hours. In both cases, intracranial hypertension was confirmed with an extradural captor. These findings are in agreement with observations of brain oedema in diabetic ketoacidosis with coma. Clinical data suggest that brain oedema may occur after a latency period but that clinical expression is much more rare, perhaps favoured by treatment (excessive rehydratation, alkalinization, too sharp drop in blood glucose level). In our cases, despite major fluid infusion, shock persisted requiring norepinephrine. This shock could have been the expression of the severe ketoacidosis or have resulted from an underlying infection. In case of sudden onset coma, a regularly encountered manifestation of brain oedema, respiratory assistance and mannitol infusion must be instituted rapidly. With this type of management, it should be possible to improve the severe prognosis of brain oedema in diabetic ketoacidosis.

Abstract
There was a marked reduction in the prevalence of complications in, and mortality status of, Japanese children with IDDM in the past 20 years. It is apparent that the improvement in medical treatment as well as social circumstance surrounding childhood diabetes in recent years contributed greatly to this change. However, when one compares Japanese data with those for Europe or the U.S., the present status is not yet satisfactory. In order to prevent the early development of diabetic complications followed by premature death associated with IDDM, an evenly distributed high-level medical system throughout Japan is required in addition to tight control of diabetes and patient education. Moreover, a population-based ongoing IDDM registry should be established from which risk factors for the progression of complications could be identified.

Abstract
Autopsy records have been published annually by the Japan Society of Pathology. We collected diabetic autopsy cases from these records (1958-1985) and analysed the causes of death. Vascular diseases comprised 38-48% of all causes of death, malignant neoplasms 16-23% and infections 16-23%. Among vascular diseases, the incidence of coronary artery diseases has increased from 6.0 to 17%, but the frequency of nephropathy and cerebrovascular diseases has remained relatively stable since 1970. Diabetic coma and tuberculosis has decreased as a cause of death, while vascular diseases and malignant neoplasm have increased during these periods. These changes reflect the trend of changing disease structure in the general population, which is partly due to the changes in age distribution of the population.

Abstract
To avoid, delay, or ameliorate the microvascular complications of diabetes, intensive insulin therapy with the goal of normoglycemia is required. In most patients with insulin-dependent diabetes mellitus (IDDM), this cannot be achieved because of severe hypoglycemia, which is one of the major causes of morbidity in diabetic patients. To assess the frequency and characteristics of severe hypoglycemia in a single diabetologist's practice, we surveyed 211 consecutive patients with IDDM for a history of severe hypoglycemia (SH), defined as events requiring the assistance of another person. Of these 211 patients, 135 (64%) had at some time had SH. Those with SH had a longer duration of IDDM, currently took more insulin injections, had a higher prevalence of neuropathy and nephropathy, and were less likely to be using human insulin. No difference was found in age, average glycosylated hemoglobin level, frequency of home glucose monitoring, or presence of retinopathy. Half of the patients with SH had confusion and were treated with glucose orally. The remainder were in coma and received i.v. glucose or IM glucagon. Perceived causes of SH were lack of food, excessive insulin, and unusual exercise. We conclude that the frequency of SH is underestimated in clinical practice. Risk factors for SH are longer duration of IDDM, presence of neuropathy and nephropathy, and use of animal insulin. Better education in avoidance and treatment of SH would reduce the morbidity of SH.

Abstract
Human cerebral cortical slices preincubated with [3H]GABA, [3H]noradrenaline, or 5-[3H]hydroxytryptamine and superfused with Krebs solution or Mg(2+)-free Krebs solution were used to investigate the influence of increased D-glucose concentrations on the release of these [3H]-neurotransmitters evoked by high K+ content or NMDA receptor activation, respectively. An increase in level of D-glucose (normal content, 11.1 mM) by 32, 60, and/or 100 mM (a range characteristic for hyperosmolar diabetic coma) increased the [3H]GABA release and inhibited the [3H]noradrenaline release evoked by both methods of stimulation. The K(+)-induced 5-[3H]hydroxytryptamine release was also inhibited by high D-glucose content. Blockade of GABAB receptors by p-(3-aminopropyl)-p-diethoxymethylphosphinic acid (CGP 35348) attenuated the inhibitory effect of high D-glucose content on the K(+)-evoked release of [3H]noradrenaline and 5-[3H]hydroxytryptamine, suggesting that the effect on monoamine release is, at least to a major part, the result of the increased GABA release and, as a consequence, of an increased GABA concentration at inhibitory GABAB receptors. The membrane-impermeable sorbitol mimicked the increasing effect of D-glucose on [3H]GABA release and its inhibitory effect on 5-[3H]hydroxytryptamine release. However, dimethyl sulfoxide, which is known to permeate rapidly through biological membranes, had no effect at concentrations equiosmolar to D-glucose. It is concluded that a reduction in brain cell volume caused by increased extracellular, compared with cytoplasmic, osmolarity is crucial for the changes in neuronal function observed at high D-glucose and sorbitol content.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
An audit of hypoglycaemic admissions among diabetic patients to Baragwanath Hospital, Soweto, South Africa was carried out prospectively during a recent 5-month period. A total of 51 episodes of biochemically confirmed hypoglycaemia (blood glucose < 2.2 mmol l-1 with coma or pre-coma, and requiring intravenous glucose) were observed in 43 patients. There was a wide range of ages (22-88 years) and an excess of males (27 M:16 F). Fourteen (33%) cases were associated with sulphonylurea (gliclazide) treatment. Doses of insulin or sulphonylureas were not excessive. The major cause precipitating the event was a missed meal (36%), though alcohol (22%), gastrointestinal upset (20%), and inappropriate treatment (18%) were also important contributory factors. Following recovery from the event, doses of drugs or insulin were frequently reduced, and three patients were successfully taken off insulin, and six off gliclazide. There was no mortality in this series, and no obvious long-term morbidity. We conclude that severe hypoglycaemia is a frequent and important acute diabetic complication in Soweto. Patient education and care in prescribing for Type 2 diabetic patients may help reduce its occurrence and severity.

Abstract
DKA-hyperosmolar coma is a readily diagnosed and easily treated, potentially catastrophic emergency that regularly occurs in both Type I and Type II diabetics. This review emphasized that diabetic ketoacidosis and hyperosmolar coma can, and very frequently do, occur concurrently, but it is the hyperosmolar state rather than the DKA that is the primary cause of coma and death in this condition. One must therefore vigorously treat the hyperosmolarity and resulting dehydration, especially when total calculated osmolarity exceeds 230 to 240 mOsm/L. The major aim of treatment is to rapidly replace the major water loss that is responsible for this clinical condition and to stimulate glucose metabolism with insulin. The diagnosis of this dangerous condition is relatively simple. The therapy, in most regards, is equally apparent. There are good data demonstrating that the prompt recognition of DKA-hyperosmolar coma and the simple institution of rapid rehydration have continued to reduce the mortality and complications of this potentially disastrous complication of diabetes mellitus.
