Alpha coma in an adolescent with diabetic ketoacidosis.

Ostojic S, Vukovic R, Milenkovic T, Mitrovic K, Djuric M, Nikolic L. Alpha coma in an adolescent with diabetic ketoacidosis. Turk J Pediatr 2017; 59: 318-321. This is the first report of alpha coma (AC) caused by brain edema in a patient with diabetic ketoacidosis (DKA). A previously healthy 15-year-old girl was admitted to the intensive care unit due to altered state of consciousness during the course of treatment for DKA. Patient was in a coma, intubated and had tachycardia with poor peripheral perfusion. Results of laboratory analyses indicated severe DKA and computed tomography scan indicated diffuse brain edema. The EEG pattern showed uniform alpha activity. Treatment with intravenous fluids, insulin and mannitol was started. Patient`s state of consciousness gradually improved and on the third day she was extubated. On the fifth day, her neurologic status and EEG findings were completely normal with no residual neurological deficits. In conclusion, although AC is associated with a high fatality rate, favorable outcome can be achieved with prompt recognition and treatment of cerebral edema in pediatric patients with DKA.

[Levosimendan treatment of severe acute congestive heart failure refractory to dobutamine/milrinone in children].

INTRODUCTION: Levosimendan is a novel positive inotropic agent which, improves myocardial contractility through its calcium-sensitizing action, without causing an increase in myocardial oxygen demand. Also, by opening ATP-sensitive potassium channels, it causes vasodilatation with the reduction in both afterload and preload. Because of the long half-life, its effects last for up 7 to 9 days after 24-hour infusion. CASE REPORT: We presented three patients 2, 15 and 17 years old. All the patients had severe acute deterioration of the previously diagnosed chronic heart failure (dilatative cardiomyopathy; univentricular heart with bidirectional Glenn anastomosis and restrictive bulboventricular foramen; bacterial endocarditis on artificial aortic valve with severe stenosis and regurgitation). Signs and symptoms of severe heart failure, cardiomegaly (cardio-thoracic index 0.65) and left ventricular dilatation (end-diastolic diameter z-score 2.6; 4.1 and 4.0) were confirmed on admission. Also, myocardial contractility was poor with ejection fraction (EF - 27%, 25%, 35%), fractional shortening (FS - 13%, 11%, 15%) and stroke volume (SV - 40, 60, 72 mL/m2). The treatment with standard intravenous inotropic agents resulted in no improvement but in clinical deterioration. Thus, standard intravenous inotropic support was stopped and levosimendan treatment was introduced. All the patients received a continuous 24-h infusion 0.1 microg/kg/min of levosimendan. In a single patient an initial loading dose of 11 microg/kg over 10 min was administrated, too. Levosimendan treatment resulted in both clinical and echocardiography improvement with the improved EF (42%, 34%, 44%), FS (21%, 16%, 22%) and SV (59, 82, 93 mL/m2). Hemodynamic improvement was registered too, with the reduction in heart rate in all the treated patients from 134-138 bpm before, to less than 120 bpm after the treatment. These parameters were followed by the normalization of lactate levels. Nevertheless, left ventricular end-diastolic diameter did not change after the levosimendan treatment. CONCLUSION: Our initial experience demonstrates that administration of levosimendan in patients with severe chronic heart failure not responsive to standard intravenous inotropic treatment might result in a significant clinical and hemodynamic improvement and that, in selected patients, it might be life saving. According to our best knowledge patients presented are the first pediatric patients treated with levosimendan in our country.

Epilepsia partialis continua in children with fulminant subacute sclerosing panencephalitis.

Various inflammatory diseases of central nervous system, including subacute sclerosing panencephalitis, could cause epilepsia partialis continua. Two boys with epilepsia partialis continua with onset in terminal phase of atypical subacute sclerosing panencephalitis have been reported. Children were not vaccinated against measles, and the second case had history of measles at an early age. In both cases, the onset of subacute sclerosing panencephalitis was characterized by altered behavior and cognitive decline with very fast mental and neurological deterioration. One boy was suffering from complex partial seizures and myoclonic jerks synchronous with periodic electroencephalographic pattern. Diagnosis was proved by increased titers of antimeasles antibodies in both serum and cerebrospinal fluid. In terminal phase of the disease, epilepsia partialis continua of localized group of the muscles was diagnosed, with good response to intravenous infusion of midazolam. Surface electroencephalographic recordings during epilepsia partialis continua did not show the epileptic discharges. During the terminal phase of the disease, no other type of seizures and movement disorders were recognized, except epilepsia partialis continua. In spite of the treatment, period from the onset of disease to death lasted less than 3 months, suggesting very fulminant course of subacute sclerosing panencephalitis.

[Use of mechanical ventilation in pediatric patients].

BACKGROUND/AIM: Major aims of mechanical ventilation (MV) in pediatrics mean the contribution to complete recovery of acute disorder or to establishing stability of previously long-term changed health condition. MV is used today in 16-46% of patients treated in pediatric intensive care units. The aim of this paper was to get insight into the presence of the disease and pathologic conditions and outcome of MV regarding previous health condition of pediatric patients. METHODS: This retrospective study included 476 pediatric patients (beyond neonatal age) who underwent mechanical ventilation (MV). On the basis of previous health status the patients were classified in two groups: the group A consisted of 157 children with no previous chronic disease leading to MV and the group H comprised of 319 children who received MV due to worsening ofprevious chronic disease. RESULTS: In both groups of pediatric patients there was significant predominance of younger age patients. Acute and chronic neurological disorders were the most frequent conditions requiring use of MV. Out of a total number (476) of the patients, 178 patients (37.40%) died. In the group A 17 patients (10.9%) died, while in the group H mortality rate was significantly higher (161 or 50.5% patients died; p < 0.01; RR 4.85; CI 3.1-7.6). Total duration time of MV in all the patients was 7 525 days, with 1 345 days (15%) accounted for the group A and 4 567 days (85%) for the group H. Mean MV duration was 7.48 (+/- 9.23) days for the patients in the group A which is significantly shorter in comparison to mean 21.8 (+/- 57.96) days for the group H patients (p < 0.001). CONCLUSION: These results point out significant contribution of MV to better outcome in pediatric patients with different acute disorders. Clear dominance of chronically ill children requiring mechanical ventilation due to acute worsening of their condition implies new complexity of problems regarding organization of pediatric intensive care and treatment.

Disseminated neonatal herpes caused by herpes simplex virus types 1 and 2.

Disseminated neonatal herpes simplex virus (HSV) infection is characterized by progressive multiple organ failure and high mortality rates. It can result from infection with either HSV-1 or HSV-2. We report a case of disseminated neonatal herpes that was caused by HSV-1 and HSV-2.
