Approach to management of malignant hyperthermia-like syndrome in pediatric diabetes mellitus.

BACKGROUND: Hyperglycemic hyperosmolar nonketotic syndrome (HHNS) is usually associated with type 2 diabetes mellitus and is rare in children. However, a fatal malignant hyperthermia-like syndrome (MHLS) with rhabdomyolysis associated with new-onset diabetes mellitus and HHNS in adolescents has been described. DESIGN/METHODS: Case series. RESULTS: A 16-yr-old obese male (case A) and a 10-yr-old mid-pubertal nonobese female (case B) presented within a 6-month period with emesis, altered mental status, blood glucose >1600 mg/dL, and laboratory evidence of rhabdomyolysis. Case A developed fever after initiation of insulin therapy, along with refractory hypotension and multiorgan failure. He died 14 hrs after admission. Case B developed fever before insulin therapy, was treated with dantrolene, and made a full recovery. Metabolic workup showed evidence of short-chain acyl-CoA dehydrogenase (SCAD) deficiency. CONCLUSIONS: We report two cases of malignant hyperthermia-like syndrome associated with HHNS in adolescents. Their respective fluid management and clinical courses are described. Dantrolene therapy should be initiated immediately after this syndrome is recognized. We believe it is unlikely insulin is the sole trigger for MHLS. Case B is unique in that there was evidence of SCAD deficiency, a metabolic defect that we propose could lead to MHLS. We recommend that all patients with HHNS and MHLS be evaluated for an underlying metabolic disorder.     

Pediatric hyperglycemic hyperosmolar coma diabeticum: diagnostic evaluation and therapeutic concept

Hyperglycemic hyperosmolar coma diabeticum (HHS) is a rare phenomenon in pediatric patients. It causes major morbidity and significant mortality. It is characterized by the trias of hyperglycemia, hyperosmolality and absent or mild metabolic acidosis. Major complications include cerebral edema and rhabdomyolysis. Evidence based guidelines for HHS in children are lacking. Based on a literature review we discuss treatment options in pediatric HHS und suggest a therapeutic concept. Appropriate treatment consists of adequate fluid administration and a cautious lowering of the serum glucose level. Patients should be treated on an intensive care unit and monitored closely to avoid complications. Low-dose and late insulin administration seems to be favourable.     

Systemic capillary leak syndrome presenting as recurrent shock.

OBJECTIVE: To report a case of systemic capillary leak syndrome (SCLS) in a child. DESIGN: Case report. SETTING: Pediatric intensive care unit. PATIENT: A 6-yr-old girl was admitted twice to the pediatric intensive care unit, at a 10-month interval, in severe shock with important edema. RESULTS: The patient presented with acute symptoms of abdominal pain, vomiting, and syncope in the hour preceding the shock. During both episodes necessary management included aggressive intravenous fluid rehydration, mechanical ventilation, and use of inotropes/vasopressors. Suspicion of a lower limb fasciitis necessitated surgical exploration, but pathology reports were negative on both occasions revealing only subcutaneous tissue edema. The patient recovered within 24 hrs on both episodes. Investigation ruled out cardiogenic shock and septic shock due to bacterial etiology. On the first episode, a nasopharyngeal aspirate was positive for influenza A (H3N2) by both viral immunofluorescence and culture. The presumed diagnosis was toxic shock syndrome associated with influenza virus. On the second episode, all bacterial and virology cultures remained negative. Hypovolemic shock was suspected, but there was no history of dehydration, bleeding, or gastrointestinal losses (persistent vomiting or diarrhea). Noninfectious causes of hypovolemic shock with edema were ruled out, leading us to believe that she suffered from SCLS. CONCLUSIONS: Although well described in the adult literature, there have been few reports of SCLS in pediatric patients. SCLS should be considered in the differential diagnosis of recurrent hypovolemic shock without identifiable cause. The only therapeutic intervention is to obtain vascular access when initial manifestations occur and give aggressive fluid reanimation.     

Atypical presentation of acute myeloblastic leukemia in two pediatric patients

Acute myeloblastic leukemia (MLA) is an uncommon disease in childhood and its prognosis is worse than that of lymphoblastic leukemia. Severe hemorrhage, infections and perfusion disorders secondary to leukostasis are the main complications leading to its high mortality rate. Two pediatric patients with MLA (M5a and M2) are presented. Both patients were admitted to the pediatric intensive care unit with acute respiratory distress syndrome and intracranial hemorrhage respectively, secondary to leukostasis. The first patient showed favorable clinical course and underwent bone marrow transplantation four months later; in contrast, the second patient died a few hours after admission. The physiopathology of each case, the therapeutic approach and the use of leukopheresis as a therapeutic alternative in patients with hyperleukocytosis and leukostasis are discussed. A high degree of suspicion is required to make a diagnosis as early as possible in order to avoid the death of a large percentage of patients before cytostatic treatment begins.     

Acute necrotizing pancreatitis in an adolescent with type 2 diabetes

PURPOSE OF REVIEW: The demographics of diabetes among adolescents are changing, with an increasing prevalence of type 2 diabetes. Since adolescents with type 2 diabetes are susceptible to the same complications that accompany type 2 diabetes in adults, pediatricians are now encountering new diagnosis entities. RECENT FINDINGS: A 16-year-old Hispanic male presented to the emergency room with new onset diabetes. Laboratory evaluation revealed the diagnosis of hyperglycemic hyperosmolar nonketotic state. Within the next 24 hours, the patient's clinical status deteriorated with multi organ failure, followed by asystole. At autopsy, the pancreas demonstrated acute necrotising pancreatitis. Hyperglycemic hyperosmolar nonketotic state is a life-threatening emergency among adults with type 2 diabetes, and is now occurring more frequently among adolescents. Acute pancreatitis should be considered as a precipitating event, particularly in those with severe hypertriglyceridemia. SUMMARY: This case illustrates the changing morbidity of diabetes in adolescents and the need to consider acute pancreatitis and hyperglycemic hyperosmolar nonketotic in adolescents with severe metabolic decompensation. Since hypertriglyceridemia is a known risk factor for acute pancreatitis, patients should be monitored, and treated as needed.     

Thrombocytopenia‐associated multi‐organ failure secondary to hyperglycemic,hyperosmolar non‐ketotic syndrome: A case report

Thrombocytopenia associated multi‐organ failure (TAMOF) is a clinical syndrome with features of new onset thrombocytopenia, increased lactate dehydrogenase, and multi‐organ failure in critically ill patients. TAMOF can be the initial presentation of an underlying disease process or can develop during the course of illness either during the hospital stay. TAMOF has a high mortality rate if not treated; therefore, early detection is critical. TAMOF has been rarely reported in diabetic ketoacidosis. We are describing the first case of a patient diagnosed with hyperglycemic, hyperosmolar non‐ketotic syndrome who developed TAMOF on the third day of his hospital course. In addition to supportive care in the intensive care unit the patient received serial therapeutic plasma exchanges and improved quickly after treatment. Early diagnosis and treatment of TAMOF decreases morbidity and mortality.     

Decompensated hyperglycemic hyperosmolarity without significant ketoacidosis in the adolescent and young adult population

AIM: To identify patients aged 10-30 years with probable hyperglycemic hyperosmolar syndrome (HHS), to describe demographic and clinical profiles, and to attempt to assess risk factors for poor outcomes. STUDY DESIGN: Retrospective cohort study (medical records review). SETTING: A 944-bed tertiary care teaching and research hospital and a 425-bed affiliated facility. PATIENTS: 10-30 year-old patients with a primary or secondary discharge diagnosis of HHS or diabetic ketoacidosis (DKA). Patients with a serum glucose >600 mg/dl in the absence of significant ketoacidosis (possible HHS) were profiled. Further stratification based on measured or calculated serum osmolarity >320 mOsm/kg (probable HHS) was undertaken. INTERVENTIONS: Patients received treatment for hyperglycemic crises, consisting primarily of fluids, electrolyte replacement and insulin. MEASUREMENTS AND MAIN RESULTS: Of the 629 admissions, 10 with a diagnosis of HHS and 33 with a diagnosis of DKA met the initial study criteria for HHS. 60% were African Americans and 89% were new-onset diabetics. From this group, 20 admissions had serum osmolarity > or =320 mOsm/kg. Fisher's exact test and Pearson coefficients were used to examine associations between risk factor and poor outcomes and correlations between admission data and length of hospital stay, respectively. Serious complications occurred in four patients (including two deaths, 10% mortality) and were limited to those with unreversed shock over the first 24 hours of admission and who received <40 ml/kg of intravenous fluids over the first 6 hours of treatment. CONCLUSIONS: HHS was underdiagnosed in this population and occurred disproportionately in African Americans. Serious complications occurred exclusively in those with unreversed shock and inadequate fluid resuscitation.     

Stroke in a child with Adams-Oliver syndrome and mixed diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome

Diabetes mellitus complicated by mixed diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome presents a special challenge to physicians. There is no standard protocol for the management of mixed hyperglycemic hyperosmolar syndrome and diabetic ketoacidosis in children. The commonest cause of neurological deterioration during an episode of diabetic ketoacidosis is cerebral edema, whereas hyperosmolality often leads to thrombosis. The risks for these complications are further increased in diseases associated with vasculopathies. We present the first case of complex cerebral arteriovenous thrombosis leading to stroke in a child with Adams-Oliver syndrome, a genetic condition that is associated with abnormal vasculogenesis. He presented with new-onset double diabetes complicated by a combination of diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome. Magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance venography provided evidence for an ischemic stroke. Children and adolescents who present with a combination of hyperglycemic hyperosmolar syndrome and diabetic ketoacidosis should be monitored for neurologic deficits and must be investigated for both stroke and cerebral edema in the event of neurological deterioration.     

Treatment of adolescents with type 2 diabetes

BACKGROUND: A worldwide increased incidence of adolescents with type 2 diabetes mellitus is evident. Only few substances are available for treatment of adolescents with type 2 diabetes. We report on our experience of treatment in the diabetes centre in Leipzig, Germany. PATIENTS AND METHODS: At the moment we care for three patients with type 2 diabetes (two girls and one boy) age 16 - 17 years. We retrospectively analyzed the patients records for symptoms at onset, BMI, HbA1c and treatment for a maximum of 4 years. RESULTS: None of the adolescents had typical symptoms at onset. All had first or second degree relatives with type 2 diabetes. Diagnosis was made using oral glucose tolerance test. BMI at onset was 26 kg/m (2) (90.-97 percent) to 35.2 kg/m (2) (>99.5 percent). Fasting and stimulated insulin and c-peptide levels were elevated in all cases. An elevated HbA1c level was found in one patient. Two patients had further metabolic symptoms like hypertriglyceridemia or hyperurikemia. We started with metformin after dietary instructions in all cases. One girl is on insulin at the moment and the boy stopped metformin after weight reduction of 24.5 kg. CONCLUSIONS: In Germany type 2 diabetes is diagnosed more frequently at an early age. Adolescents with type 2 diabetes should be treated in a centre for pediatric diabetology. Treatment should consist of an individualized care for all aspects of type 2 diabetes.

Infants with myocarditis presenting with severe respiratory distress and shock

The characteristics of four infants with myocarditis who presented to the emergency department with acute onset of severe respiratory distress and shock are presented. Although history and physical findings were not supportive of hypovolemic shock or bronchospasm, three of the four infants received an intravenous fluid bolus, and two were given bronchodilator therapy. All patients had metabolic acidosis, and three had cardiomegaly on chest x-ray. Two patients survived. Initial recognition and stabilization of the pediatric patient with cardiogenic shock secondary to myocarditis is reviewed.     

The treatment and prevention of diabetic ketoacidosis in children and adolescents with type I diabetes mellitus.

There remain a number of important controversies in the management of pediatric DKA. From the sodium content of the hydrational fluid to the rate of fluid administration that is best able to reverse the hyperosmolar dehydration attendant with DKA with minimal morbidity and mortality, there is no universal agreement on how patients with this devastating metabolic disturbance should be treated. It is still unclear what promotes or protects patients from neurologic insult during DKA reversal. It is appropriate to begin to develop a national approach to eradicating DKA. This would require widespread public and professional education programs aimed at detecting new-onset type I patients prior to the onset of DKA. It would involve promoting diabetes screening programs aimed at detecting patients before the onset of symptomatic disease, and these would most appropriately be centered in the pediatrician's office. In the known patient, DKA still occurs as the result of intercurrent illness and nonadherence to the diabetes regimen due to patient or family chaos and dysfunction. Clearly, more strategies are needed to address these psychological and family patterns and the fact that many tenuous families have insufficient access to appropriate medical care. Those caring for children and adolescents must do all they can to prevent DKA and to treat it optimally to avert the toll this metabolic aberration takes on the pediatric diabetes population.     

A ‘radical’ new rural model for pediatric diabetes care

Goss PW, Paterson MA, Renalson J. A ‘radical’ new rural model for pediatric diabetes care. Objective: The purpose of the study was to evaluate a new rural Australian multidisciplinary model of pediatric diabetes care. Methods: In 2007, in response to insurmountable obstructions to establish an effective multidisciplinary team within the public health system, an Australian rural pediatric practice created a private multidisciplinary diabetes care model. The ‘Rural Australian Diabetes –Inspiring Control Activity & Lifestyle’ model –‘RADICAL’–comprised a locally based, co‐located core team of general pediatrician, diabetes educator, and mental health nurse. Regular diabetes clinics were established, including team meetings where each individual patient was discussed. Therapy included proactive child and family emotional support and promotion of insulin regimes that aimed to match patient lifestyle, especially insulin pump therapy. By 2009, 56 of 61 children and adolescents with type 1 diabetes across a broad regional area had access to the model of care. The model was evaluated in terms of metabolic control, patient satisfaction, and quality of life. Results: Since the RADICAL model was established, the average HbA1c has fallen from mean 9.6% ± 1.81 (median 9.7%) in 2006 to mean 8.1% ± 1.25 (median 7.9%) in 2009 (p < 0.001). Patient satisfaction with the model was overwhelming. The previously demonstrated reduced quality of life of Australian rural diabetic youth compared with urban diabetic youth was eliminated. Conclusion: Multidisciplinary child diabetes care can be successfully achieved in rural settings using local resources with results comparable to international tertiary multidisciplinary diabetes units.     

RHABDOMYOLYSIS DUE TO Escherichia coli SEPSIS IN THREE PEDIATRIC PATIENTS WITH ACUTE LYMPHOBLASTIC LEUKEMIA

Rhabdomyolysis with myoglobinuria is an uncommon complication of bacterial sepsis. The authors describe three pediatric acute lymphoblastic leukemia patients who developed rhabdomyolysis during a neutropenic sepsis episode due to Escherichia coli. All of the patients needed hemodynamic supportive treatment because of septic shock. Broad-spectrum antibiotics, alkalinization, and intravenous fluid therapy was given. One patient with renal insufficiency died, despite aggressive treatment. Muscle pain and dark urine color should alert physicians to the possibility of rhabdomyolysis in immunocompromised patients with sepsis. Early and appropriate treatment is critical in these patients to prevent renal failure and shock, and for a better outcome.     

Aggressive management of dengue shock syndrome may decrease mortality rate: a suggested protocol.

OBJECTIVES: Dengue shock syndrome is a leading cause of mortality among Indian children. In January 2000, we instituted a protocol for aggressive management of children with dengue shock syndrome. The objective of this study was to compare outcomes (duration of ventilation, pediatric intensive care unit stay, incidence of acute respiratory distress syndrome, and intensive care unit and hospital mortality) before and after the protocol. DESIGN: Retrospective chart review. SETTING: Pediatric intensive care unit at a tertiary teaching hospital. PATIENTS: One hundred and fourteen patients admitted between July 1997 and December 1999 received standard therapy recommended by the World Health Organization (WHO) and were designated as the WHO guidelines group (W), whereas 96 patients admitted between January 2000 and December 2001 were treated by our protocol and designated as the protocol group (P). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The patients in each group were equally matched in terms of age, Pediatric Risk of Mortality, and number with dengue hemorrhage fever grade IV, although the platelet counts were higher in the W group compared with the P group (geometric mean 42.2, confidence interval 36.9, 48.4 vs. geometric mean 36.7, confidence interval 33.3, 40.5, p < .05). Patients in the W group received less fluids in the first hour compared with the P group (median and interquartile range 20 mL/kg, 15 and 20 vs. 30 mL/kg, 20 and 60). Fluid was actively removed less often in the W group than the P group (6 of 111 vs. 45 of 96, p < .05). There was no difference in the need for ventilation or incidence of acute respiratory distress syndrome between groups, although among dengue hemorrhage fever grade IV patients, the number requiring ventilation (17 of 30 vs. 20 of 23, p < .05) and the incidence of acute respiratory distress syndrome (9 of 30 vs. 17 of 23, p < .05) were significantly greater in the W group compared with the P group. The duration of ventilation (1.5 +/- 1.7 vs. 4.2 +/- 2.9 days, p < .05) and length of intensive care unit stay (3.0 +/- 2.8 vs. 3.4 +/- 2.9 days, p < .05) were significantly less in the W group. The pediatric intensive care unit mortality (16.6% vs. 6.3%, p < .05) was significantly higher in the W group than in the P group. CONCLUSIONS: Patients with dengue shock syndrome are at high risk of mortality due to refractory shock and multiple organ failure. Survival was better for patients in the P group. Aggressive shock management and possibly the use of judicious fluid removal may decrease mortality rates in the severest forms of dengue shock syndrome.     

Mortality before and after initiation of a computerized physician order entry system in a critically ill pediatric population.

OBJECTIVE: A worrisome increase in mortality has been reported recently following the initiation of a computerized physician order entry (CPOE) system in a critically ill pediatric transport population. We tested the hypothesis that such a mortality increase did not occur after the initiation of CPOE in a pediatric population that was directly admitted to the neonatal and pediatric intensive care units at Montefiore Medical Center during two 6-month periods before CPOE and one 6-month period immediately after CPOE was initiated. Mortality in the pre- and post-CPOE time periods was compared, and adjustment for potentially confounding covariates was performed. SETTING: The pediatric and neonatal intensive care units at Montefiore Medical Center. PATIENTS: All patients admitted from the emergency room or operating room or as transfers from other institutions directly to the pediatric and neonatal intensive care units at Montefiore Medical Center. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Overall, 29 (3.16%) of the 917 patients in the pre-CPOE period and nine (2.41%) of the 374 patients in the post-CPOE period died during their hospital stay (p = .466). The power to detect the hypothesized mortality increase was 81.7%. The variables that remained significant risk factors for mortality after adjustment were shock (odds ratio, 9.41; 95% confidence interval, 2.90-30.49), prematurity (odds ratio, 3.57; 95% confidence interval, 1.74-7.30), male gender (odds ratio, 3.31; 95% confidence interval, 1.47-7.69), or a hematologic/oncologic diagnosis (odds ratio, 3.14; 95% confidence interval, 1.44-6.86). Post-CPOE initiation status remained unassociated with mortality after adjusting for all covariates (odds ratio, 0.71; 95% confidence interval, 0.32-1.57). CONCLUSION: Mortality did not increase during CPOE initiation.     

The role of new technologies in treating children and adolescents with type 1 diabetes mellitus

Abstract:  Given the physiological and psychological impact of type 1 diabetes in children and adolescents, these patients present special challenges to pediatric health care providers. The goals of intensive management of diabetes have been clearly established since the publication of the Diabetes Control and Complication Trial (DCCT) in 1993 (1), which demonstrated that tight metabolic control achieved with intensive insulin therapy is superior to conventional treatment in reducing the risk of long-term microvascular complications. Thus, current recommendations mandate that youth with type 1 diabetes should aim to achieve metabolic control as close to normal as possible. However, strict glycemic control is hard to achieve requiring frequent blood glucose measurements and several insulin injections per day, and in addition is associated with an increased risk of severe hypoglycemia (1). Recurrent episodes of hypoglycemia, especially at young ages, may cause adverse effects on neurocognitive function, may lead to hypoglycemia unawareness, and may be associated with significant emotional morbidity for the child and parents. Since the discovery of insulin in 1921 there has been constant progress in the way patients with type 1 diabetes are treated. The introduction of recombinant insulin and insulin analogs as well as new insulin delivery systems and glucose monitoring devices enhanced the ability of both patients and medical teams to better define the therapeutic goals and to develop more effective therapeutic strategies. Recent advances in devices for insulin administration and glucose monitoring and the introduction of telemedicine are having a profound effect on the lives of youth with type 1 diabetes. This review focuses on the new technologies which have been developed for treating children and adolescents with type 1 diabetes.     

The use of recombinant factor VIIa in a patient with Noonan syndrome and life-threatening bleeding.

OBJECTIVE: To present a case report of a patient with Noonan syndrome who developed life-threatening gastrointestinal bleeding shortly after cardiac surgery that was successfully treated with recombinant factor VIIa. DESIGN: Case report. SETTING: Pediatric intensive care unit of a children's hospital. PATIENT: Ten-month-old with Noonan syndrome and massive gastrointestinal bleeding resulting in severe hypovolemic shock. INTERVENTIONS: Recombinant factor VIIa was used in this patient's severe bleeding associated with Noonan syndrome after no other supportive measures were successful. MEASUREMENTS AND MAIN RESULTS: Recombinant Factor VIIa significantly decreased the patient's bleeding and allowed his hypovolemic shock to improve. Ultimately, the patient made a complete recovery. CONCLUSIONS: Noonan syndrome has a constellation of both cardiac and noncardiac malformations including an increased risk of bleeding, and recombinant factor VIIa is an important agent in the treatment of significant bleeding.     

Renal replacement therapy in pediatric critical care medicine

PURPOSE OF REVIEW: The use of continuous renal replacement therapy in pediatric critical care has increased in the last 10 years. Adaptive makeshift machinery has been replaced with dedicated volumetric and/or gravimetric devices that afford accurate blood flow and ultrafiltrate production rates. While renal dysfunction continues to be related to primary renal disease, the incidence of secondary causes of acute renal failure continue to grow, especially in patients following cardiothoracic surgery, bone marrow transplantation, respiratory failure and multi-organ dysfunction syndrome. RECENT FINDINGS: Although much of the outcome data for continuous renal replacement therapy has been retrospective in nature, these therapies are safe for use in the sickest of intensive care unit patients. Moreover, early data from the prospective pediatric continuous renal replacement therapy registry suggests that early intervention with continuous renal replacement therapy, as well as goal-directed fluid resuscitation may lead to improved survival in critically ill patients. In patients with sepsis and septic shock, continuous renal replacement therapy offers a means for blood purification. SUMMARY: Though randomized placebo controlled trials are lacking at this time, center-based results suggest that continuous renal replacement therapy may prove beneficial to critically ill patients with sepsis and/or septic shock.     

Diabetic ketoacidosis: predictors of outcome in a pediatric intensive care unit of a developing country.

OBJECTIVES: To study the outcome and predictors of mortality in children with diabetic ketoacidosis. DESIGN: Retrospective case series. SETTING: Pediatric intensive care unit of an urban multiple-specialty teaching and referral hospital in north India. PATIENTS: Sixty-eight patients with diabetic ketoacidosis treated between 1993 and 2000. INTERVENTIONS: Data were retrieved from case records with respect to patients' age; clinical features; osmolality at admission; blood glucose, serum potassium, and arterial pH at admission, 6 hrs, and 24 hrs; complications during the course of hospital stay; treatment; and outcome in terms of survival or death. Survivors and nonsurvivors were compared to determine the predictors of mortality. MEASUREMENTS AND MAIN RESULTS: The mean (sd) age of the study population was 6.9 (3.5) yrs (range, 0.5-12 yrs). Impaired consciousness (n = 45; 66%), rapid breathing (n = 41; 60%), and vomiting (n = 35; 51.4%) were common presenting symptoms. Thirty-two (50%) patients had clinically evident dehydration. Precipitating events identified were new-onset diabetes with sepsis (37%), new-onset diabetes alone (31%), insulin omission (15%), and infection with insulin omission (7%). The mean (sd) blood glucose, osmolality, and pH at admission were 473 (sd 184) mg/dL, 305 (sd 24) mOsm/L, and 7.08 (sd 0.1), respectively. Complications noted during treatment were hypokalemia (n = 28; 41%), hypoglycemia (n = 10; 15%), cerebral edema (n = 9; 13.2%), and pulmonary edema (n = 2; 3%). Nine (13.2%) patient died, with the causes of death being septic shock (n = 4), cerebral edema (n = 2), cerebral edema with pulmonary edema (n = 2), and hypokalemia with ventricular tachycardia (n = 1). Those who died were older, had higher osmolality and severe acidosis at admission, and had persistent hyperglycemia and acidosis at 6-12 hrs. On multiple logistic regression analysis, osmolality at admission was the most significant predictor of death. CONCLUSIONS: Two thirds of children with diabetic ketoacidosis in our series had new-onset diabetes, and 13.2% died. Serum osmolality at admission was the most important predictor of death.
