Abstract
Pour évaluer l'énurésie, un trouble pédiatrique courant, il faut en distinguer la forme monosymptomatique de la forme non monosymptomatique et établir la présence d'affections concomitantes. La prise en charge simultanée des facteurs cooccurrents est le meilleur moyen pour obtenir un résultat satisfaisant. Le traitement commence par l'éducation du patient et de sa famille sur l'évolution naturelle de l'énurésie et par des conseils pratiques sur le comportement. Les données probantes en appui à des interventions particulières sont limitées, et les enfants et les familles devraient participer au choix du traitement approprié. Les dispositifs d'alarme contre l'énurésie et la desmopressine représentent des possibilités thérapeutiques lorsqu'une intervention plus active est souhaitée. Des améliorations cliniques et des traitements combinés sont en voie de se dégager.

Abstract
Assessing enuresis involves distinguishing monosymptomatic from non-monosymptomatic for this common paediatric problem, and identifying concomitant comorbidities. Addressing co-occurring factors concurrently ensures the best opportunity for a satisfactory outcome. Treatment begins with patient and family education on the natural history of enuresis and practical behavioural guidance. Evidence to support particular interventions is limited, and children and families should be involved when choosing appropriate therapy. Enuresis alarms and desmopressin are treatment options when more active intervention is desired. Clinical refinements and combined treatment modalities are emerging.

Abstract
BACKGROUND Amitriptyline ingestion is an important cause of poisoning morbidity and mortality in Turkey and other countries. In contrast to adults, data concerning amitriptyline intoxication in children are limited. The purpose of this study was to investigate amitriptyline intoxication findings in the pediatric population, based on age groups and reported dosages. METHODS The medical records of 192 patients admitted to the Karadeniz Technical University Medical Faculty Farabi Hospital Pediatric Emergency Department, Turkey, due to amitriptyline intoxication in 1997-2017 were examined retrospectively. Patients were divided into 6 groups based on amitriptyline doses and 4 groups based on age. Complete blood count, blood glucose, serum electrolytes, renal and liver function tests, coagulation tests (prothrombin time and partial thromboplastin time), and blood gas analysis were studied in all patients. Electrocardiography was performed on all children, and chest radiography and electroencephalography on those with respiratory or central nervous system symptoms. RESULTS Amitriptyline intoxication was most frequently observed between the ages of 1 and 4 years. The most common signs and symptoms observed at time of hospital admission were lethargy and drowsiness (45.3%), sinus tachycardia (19.2%), and nausea and vomiting (13%). The most common laboratory finding was hyperglycemia (17.7). Six patients were intubated because of respiratory failure, and mechanical ventilation was initiated in these cases. One patient with amitriptyline overdose had persistent supraventricular tachycardia. Four children died due to amitriptyline intoxication. CONCLUSIONS Tricyclic antidepressant intoxication is a leading cause of mortality and morbidity in children. It is therefore particularly important to identify the clinical and laboratory findings that develop with high-dose consumption.

Abstract
Chronic abdominal pain is frequently encountered in pediatric practice. A large proportion of cases meet Rome criteria for abdominal pain-functional gastrointestinal disorders (AP-FGIDs). These disorders are costly and, in some cases, lead to impairment of daily functioning and overall quality of life. Pathophysiologic mechanisms include early stressful events, visceral hypersensitivity, dysmotility, changes in intestinal microbiota, and altered central nervous system processing. They are considered disorders of the brain-gut interaction. The diagnosis is made on clinical grounds using symptom-based criteria (Rome criteria). Anxiety and depressive symptoms are more prevalent in patients with AP-FGIDs. Therefore, attention has been directed to the use of neuromodulators as potential interventions for AP-FGIDs. Antidepressants are one type of neuromodulators, and one of the most studied drugs for the management of AP-FGIDs in adult and pediatric population. Data available in pediatric population have significant limitations including nonuniform methodology with different study designs and primary endpoints. Evidence of the efficacy of antidepressants in the management of pediatric AP-FGIDs is not consistent. There is an urgent need for well-designed randomized clinical trials using age-appropriate validated outcome measures. Careful consideration must be given to adverse effects, particularly increased suicidal ideation.

Abstract
The aim of this study was to evaluate HRV in children requiring intensive care unit stays due to TCA poisoning between March 2009 and July 2010. In the time-domain nonspectral evaluation, the SDNN (P < 0.001), SDNNi (P < 0.05), RMSDD (P < 0.01), and pNN50 (P < 0.01) were found to be significantly lower in the TCA intoxication group. The spectral analysis of the data recorded during the first 5 minutes after intensive care unit admission showed that the values of the nLF (P < 0.05) and the LF/HF ratio (P = 0.001) were significantly higher in the TCA intoxication group, while the nHF (P = 0.001) values were significantly lower. The frequency-domain spectral analysis of the data recorded during the last 5 minutes showed a lower nHF (P = 0.001) in the TCA intoxication group than in the controls, and the LF/HF ratio was significantly higher (P < 0.05) in the intoxication group. The LF/HF ratio was higher in the seven children with seizures (P < 0.001). These findings provided us with a starting point for the value of HRV analysis in determining the risk of arrhythmia and convulsion in TCA poisoning patients. HRV can be used as a noninvasive testing method in determining the treatment and prognosis of TCA poisoning patients.

Abstract
Amitriptyline (AMT) is commonly used in the management of children with irritable bowel syndrome. AMT is pro-arrhythmogenic and increases the risk of sudden cardiac death. However, there is not enough data regarding the cardiac toxicity in therapeutic doses of AMT in children and the need for screening electrocardiogram (EKG). Errors in computer EKG interpretation are not uncommon. In a risk-prevention study, the authors sought to identify the true incidence of prolonged corrected QT (QTc) interval and other arrhythmias in children with irritable bowel syndrome before the initiation of AMT. Out of the 760 EKGs screened, 3 EKGs demonstrated a true prolonged QTc after the careful manual reading by a pediatric cardiologist and they were not picked by computer-generated reading. The authors conclude that screening EKG should always be performed on children before initiating AMT therapy. Also, the computer-generated EKG needs to be verified by a pediatric cardiologist to avoid serious misinterpretations.

Abstract
Amitriptyline, a tricyclic antidepressant, has a well-described toxicity profile, and acute ingestions are common in the pediatric toxicology world. However, little can be found in the literature regarding chronic overdose. We describe a case of a 6-year-old girl who was prescribed amitriptyline 30 mg nightly for sleep problems, but was mistakenly given 300 mg (15 mg/kg) nightly for over a month. She was noted to have mental status changes and difficulty reading several days after starting the medication. She presented to the local children's hospital in status epilepticus with significant cardiac conduction abnormalities on ECG. Her total amitriptyline/nortriptyline level was found to be 1676 ng/mL (normal therapeutic level 50-300 ng/mL). She was treated for several days with sodium bicarbonate. Within 24 h, her neurologic status improved and had returned to baseline within several days. Her ECG normalized, and she was discharged home, without apparent sequelae. A brief discussion of possible protective mechanisms (including pharmacogenomic) is presented.

Abstract
Tricyclic antidepressants (TCAs) account for approximately 3% of all pediatric hospitalizations due to poisoning. TCAs remain a common cause of fatal drug poisoning because of their cardiovascular toxicity as manifested by electrocardiogram (ECG) abnormalities, arrhythmias, and hypotension. We report a 15-year-old girl with junctional escape rhythm and resistant hypotension caused by severe imipramine intoxication. Initial ECG showed junctional escape rhythm (46 bpm) with no atrial activity, low QRS voltage, widening of the QRS complex (160 ms) with a right bundle branch-like pattern, R wave > 3 mm in aVR (6 mm), and prolongation of the QT interval (QTc 550 ms). Despite intravenous fluids and inotropic support, she had resistant hypotension and acute renal failure. Junctional rhythm was successfully terminated by using temporary cardiac pacemaker. Hemodialysis and hemoperfusion were also performed. She was discharged on the day 5 without any complications. During follow-up, no ECG abnormalities were noted. We reported successful use of temporary cardiac pacemaker for treatment of junctional rhythm and resistant hypotension in imipramine intoxication. The conventional methods of activated charcoal, alkalinization, and symptomatic treatment of complications are usually enough for nonlethal doses of TCA intoxication. However, in imipramine intoxication with serious arrythmias and hypotension, using temporary cardiac pacemaker, hemodialysis, and hemoperfusion can be a life-saving therapeutic approach.

Abstract
BACKGROUND Amitriptyline is one of the major tricyclic antidepressants, and the data on amitriptyline poisoning in children are limited. OBJECTIVES To present our experiences with amitriptyline poisoning in children, particularly with regard to its effects on electrocardiogram (ECG) and relation with clinical status. METHODS Clinical, laboratory, and electrocardiographic findings in 52 children admitted with amitriptyline poisoning were reviewed. Patients were divided into 2 groups according to age, as 6 years or younger (group A) and older than 6 years (group B). RESULTS Mean age was 4.6 +/- 3.0 years. Thirty-one patients were male, and 41 were 6 years or younger. Ingested amitriptyline dose was known in 23 patients (range, 2.3 mg/kg-27 mg/kg). The most frequent findings were lethargy (76.9%), sinus tachycardia (57.7%), and coma (48.1%). Four patients had a history of convulsion. The most common laboratory abnormalities were hyponatremia (26.9%) and leukocytosis (25%). Elevated transaminase levels were observed in 4 patients. In ECG, 11 (22.4%) patients had QTc prolongation and in 4 (8.2%) of them, it was significant. In 4 patients (8.2%), the QRS duration was 100 ms or longer and in 15 patients, the R wave in aVR was 3 mm or longer. The frequencies of clinical, laboratory, and electrocardiographic findings were similar between the 2 age groups (P > 0.05). No clinically apparent arrhythmias were observed. The positive predictive value of a widened QRS was 100% in terms of coma. None of the patients with an R wave in aVR of less than 3 mm developed convulsion; thus, the negative predictive value of an R wave in aVR of 3 mm or longer was 100% in terms of convulsion. CONCLUSIONS Amitriptyline poisoning may result in severe toxicity. Frequencies of clinical, laboratory, and ECG findings were similar in the 2 age groups. Amitriptyline overdose results in some ECG changes that can possibly help to predict the results of poisoning. Absence of an R wave in aVR of 3 mm or longer predicts seizures with a high negative predictive value, and a QRS duration of 100 or longer ms predicts coma with a high positive predictive value.

Abstract
BACKGROUND The aim of this study was to examine the characteristics of seizure due to poisoning. METHODS This was a retrospective analysis, throughout 4 years of hospital admissions for poisoning. Data of patients with seizures due to poisoning were evaluated with respect to the causes, frequencies and complications of seizures. RESULTS Among the 1561 admissions due to intoxication during the review period, seizures developed in 26 cases (1.6%). Tricyclic antidepressant overdose (n = 11, 42%) was the leading cause of seizure due to poisoning. Generalized tonic-clonic seizures were observed in 24 patients. Status epilepticus developed in six patients (23%). Mechanical ventilation was applied in 12 (46%) patients. Cardiac complications were observed in 11 (42%) patients with seizures. Two patients who had cardiac arrest due to acepromazine maleate and imipramine intoxication died. CONCLUSION One of the causes of seizures in pediatric age group is intoxication. Seizures due to intoxications may cause serious clinical conditions. Intoxications should be thought when a patient is admitted with the diagnosis of afebrile seizure even if there is no history of drug intake.

Abstract
Contrary to existing evidence, convulsant liability of the antidepressants has been attributed to noradrenergic and serotonergic increments. This is a classic case of confusing treatment effects with the manifestations of illness. In fact, the remarkable anticonvulsant effectiveness of antidepressant-induced noradrenergic and serotonergic activation has been ignored. Some antidepressant drugs such as the specific serotonin reuptake inhibitor (SSRI) fluoxetine may be devoid of convulsant liability entirely, while having distinct anticonvulsant properties. Some authorities advance the notion that the seizure predisposition of patients with epilepsy increases risks for antidepressant-induced seizures. However, evidence does not support this contention. Instead, data increasingly support the concept that noradrenergic and serotonergic deficiencies contribute to seizure predisposition. Indeed, the antidepressants have the potential to overcome seizure predisposition in epilepsy. Whereas therapeutic doses of antidepressants elevate noradrenergic and serotonergic transmission, larger doses can activate other biological processes that may be convulsant.

Abstract
Tricyclic antidepressants (TCA), increasingly prescribed for multiple indications in children and adults, are responsible for many pediatric poisonings. Though the majority of TCA exposures in this age group remain asymptomatic, several reports in the English language literature reveal significant morbidity as well as fatalities in toddlers, primarily from imipramine and desipramine. These few cases indicate that doses of 10-20 mg/kg (one to two pills) have the potential for toxicity and fatalities. More recent studies have focused on the relative safety of small exposures suggesting that with doses less than 5 mg/kg the patient may be safely observed at home. Though further studies are necessary to determine the exact dosing that places the child at risk, the authors recommend a 6-h Emergency Department observation period for children who ingest more than 5 mg/kg of most TCAs, as clinical toxicity becomes evident within this time frame.

Abstract
OBJECTIVES To systematically review and summarize studies on the accuracy of ECG and tricyclic antidepressant (TCA) concentration as prognostic indicators of the risk of seizures, ventricular arrhythmia (VA) or death in patients with TCA overdose. METHODS Articles were identified with MedLine and Cochrane register of controlled clinical trials searches and review of medical toxicology textbooks. Quality of the included studies was assessed. Pooled estimates of sensitivity, specificity, likelihood ratios and Summary Receiver Operating Characteristics (SROC) curves were generated. RESULTS A total of 18 studies were included in the analysis. The pooled sensitivity (Se) and specificity (Sp) of the QRS for predicting seizures were 0.69 [95% CI 0.57-0.78] and 0.69 [95% CI 0.58-0.78] as compared to 0.75 [95% CI 0.61-0.85] and 0.72 [95% CI 0.61-0.81] for the TCA concentration. The Se and Sp of the QRS to predict VA were 0.79 [95% CI 0.58-0.91] and 0.46 [95% CI 0.35-0.59] compared to 0.78 [95% CI 0.56-0.90] and 0.57 [95% CI 0.46-0.67] for the TCA concentration. The Se and Sp of the QRS to predict death were 0.81 [95% CI 0.54-0.94] and 0.62 [95% CI 0.55-0.68] compared to 0.76 [95% CI 0.49-0.91] and 0.60 [95% CI 0.47-0.72] for the TCA concentration. Very few studies evaluated the accuracy of QTc, T 40 ms axis and the R/S ratio. CONCLUSIONS Overall, the studies suggested that the ECG and TCA concentration have similar but relatively poor performance for predicting complications, such as seizures, VA or death, associated with TCA overdose.

Abstract
The newer antidepressants are as efficacious as the older agents in the treatment of depression. They have a side effect profile that is different from the older drugs and are generally better tolerated. Drug-drug interactions do exist with some of these agents and can usually be predicted from knowledge of their metabolism. When taken in overdose as the sole agents they are rarely fatal; seizures, nausea, vomiting, decreased level of consciousness, and tachycardia are common. In combination with other drugs, toxicity can be more severe. The serotonin syndrome can occur with many of these drugs, and the emergency physician must be vigilant in the evaluation of the overdose patient. CAs and older MAOIs are still in use and remain dangerous when taken in overdose. Patients asymptomatic after a period of observation in the ED usually can be discharged after psychiatric evaluation, when it is required.
