Comorbidity of behavioral problems and parental acceptance-rejection in children diagnosed with chest discomfort, palpitations, vasovagal syncope, and underlying heart disease: a multiple case-control study

BACKGROUND

Children who experience chest discomfort, palpitations, vasovagal syncope, and underlying heart disease often present a complex clinical picture. Not only are they dealing with potential cardiac issues, but they may also exhibit behavioral problems that can complicate the diagnostic and treatment process. Moreover, parental acceptance or rejection can significantly influence the child's well-being and medical outcomes in such cases. This study aims to explore the comorbidity of behavioral problems and parental acceptance-rejection in children diagnosed with these cardiac symptoms and underlying heart disease.

METHODS

In a case-control study, the Parental Acceptance - Rejection Questionnaire and Parental version of Strengths and Difficulties Questionnaire (SDQ) was filled by parents of 314 patients from pediatric cardiology clinic.

RESULTS

The control group scored substantially lower overall according to SDQ. The vasovagal syncope subgroup was found to have considerably lower scores on the subscale. The group with chest discomfort scored highly in hostility and aggression in the PARQ. In comparison to the other groups, the vasovagal syncope and chest pain group demonstrated higher scores in undifferentiated rejection and total score.

CONCLUSION

This study showed a correlation between children's behavioral and emotional problems and cardiac symptoms. This states that children's relationship with their parents has an impact on their symptoms. It will be necessary to conduct further studies to determine a causal association and devise preventative measures.

A Challenging Interventional Procedure: Transcatheter Closure of Tubular Patent Ductus Arteriosus in Patients with Pulmonary Hypertension

Transcatheter closure of the tubular ducts remains the most challenging procedure, with higher complication rates than other types. This study evaluates the characteristics of transcatheter closure of tubular ducts with pulmonary hypertension. 73 patients with tubular ducts who underwent cardiac catheterization for transcatheter PDA closure were analyzed. The mean age and weight were 1.93 ± 2.68 years and 8.83 ± 6.14 kg, respectively. Transcatheter closure was attempted in 72 patients. Four cases (5.5%) were referred to surgery, while the procedure was completed in the remaining (94.5%). Amplatzer duct occluder (ADO) I or Cardiofix duct occluder (CDO) was the most commonly used devices. However, the use of Amplatzer vascular plug (AVP) II raised in recent years. The most common concern was aortic protrusion/stenosis in ADO I/CDO devices, but most regressed during follow-up. Iatrogenic coarctation of the aorta was observed in two with ADO I/CDO. Embolization of the device to the pulmonary artery was observed in three with CDO, AVP II, and AVP I. Significant left pulmonary artery stenosis requiring stenting developed in one after closure with an MVSDO device. Tubular ducts are highly associated with pulmonary arterial hypertension, and transcatheter closure of them is still challenging despite the developing device armamentarium. Although ADO I or similar devices are widely used, off-label devices are usually needed at increasing rates. The AVP II device is unsuitable for short tubular ducts but seems the best option for long ones.

Effects of levetiracetam treatment on autonomic nervous system functions in pediatric epilepsy patients

BACKGROUND

This study investigated the effects of levetiracetam (LEV) treatment on cardiac rhythm and heart rate variability.

METHODS

The study included two groups of patients diagnosed with non-lesional epilepsy who had not yet been treated and who presented to the outpatient pediatric neurology clinic at Van Training and Research Hospital, Van, Turkey, between 2019 and 2020. The heart rate variability (HRV) of 47 patients in the first group, before and at the 3rd month of treatment, and intravenous (IV) LEV loading in 13 patients in the second group was evaluated by Holter electrocardiography (ECG).

RESULTS

It was determined that the values of triangular index, standard deviation of the RR intervals over a 24-hour period (SDNN), standard deviation of all 5-minute mean RR intervals (SDANN), mean of standard deviations of all normal RR intervals (SDNNI), the percentage of RR intervals with >50-millisecond variation (PNN50), and the square root of mean squared differences of successive RR intervals (RMSSD). HRV of 47 patients under LEV treatment significantly increased in the 3rd month of treatment compared to baseline (p < 0.05). No difference was found in HRV between the intravenous loading and the control group (p > 0.05).

CONCLUSIONS

Our study suggests that the sympathovagal balance before treatment in the patient group is in favor of the sympathetic nervous system and that the sympathovagal imbalance improves after treatment. Our results show that LEV monotherapy and loading have no negative effect on HRV and potential cardiac arrhythmia risk in children with epilepsy.

A rare cause of hydrops fetalis in two Gaucher disease type 2 patients with a novel mutation

Gaucher disease type 2 is the most progressive and the rarest form of Gaucher disease, defined as the acute neuronopathic type. We presented two GD2 patients who died before three months of age due to severe septicemia, respiratory and liver failure. One was homozygous for a novel GBA variant c.590 T > A (p.197 K), and the second homozygous for the known GBA mutation c.1505G > A (p.R502H). Ichthyosis, hydrops fetalis, apnea, myoclonic seizures, and hepatosplenomegaly occurred in both patients, but hypertrophic cardiomyopathy was observed only in the second and unilateral cataract in the first patient. Due to the disease's early and rapid neurological progression, we did not administer ERT to our patients. It is strongly believed that early diagnosis is essential, and prenatal diagnosis makes genetic counselling possible for future pregnancies.

Efficacy of levetiracetam in the treatment of Sydenham chorea

BACKGROUND

To study the effect of levetiracetam in treating Sydenham chorea.

METHODS

We retrospectively collected the data of 140 patients diagnosed with Sydenham chorea in the pediatric neurology and pediatric cardiology outpatient clinics of Van Training and Research Hospital between January 2010 and December 2018.

RESULTS

There were 140 patients, 102 (70%) of whom were girls, with mean age of onset 11.8 ± 2.7 years. Symptomatic treatment was initiated in all patients at the time of diagnosis; this medication was changed during follow up in 15 patients. The most frequently prescribed drugs were haloperidol and sodium (Na) valproate, and the most frequently discontinued one was haloperidol, due to side effects. The second-choice drug was most often levetiracetam. Clinical response often began within the first 2 weeks, with Na valproate (P = 0.002), within 4 weeks with carbamazepine (P = 0.037) but 1-6 months with haloperidol (P = 0.018) and levetiracetam (P = 0.008). Time to full remission was similar with Na valproate, carbamazepine, haloperidol, and levetiracetam (P = 0.276). Our study indicated that levetiracetam was as effective as the other commonly used drugs in the symptomatic treatment of Sydenham chorea.

CONCLUSION

Levetiracetam might be an option in the treatment of Sydenham chorea because of its acceptable effect and safety profile. This observation needs further support with evidence obtained through controlled and blinded trials.

Evaluation of left and right ventricular functions using conventional and tissue Doppler echocardiography in children with type 1 diabetes mellitus

BACKGROUND

The aim of the study was the evaluation of the effects of glycemic control in children and adolescents with type 1 diabetes on cardiac functions.

METHODS

Diabetic patients were divided into two groups as well-controlled and poorly controlled patients. All patients underwent M-mode, two-dimensions (2D), pulsed wave (PW) Doppler, and tissue Doppler (TDI) echocardiography to evaluate systolic and diastolic functions.

RESULTS

Early diastolic mitral flow velocity (Em) and the ratio of early to late diastolic mitral flow velocity (Em/Am) obtained with TDI were found to be significantly lower in the well-controlled then the control group and significantly lower in the poorly-controlled group than the well-controlled group. Am, isovolumetric relaxation time (IVRT) and myocardial performance index (MPI) were significantly higher in the poorly controlled group. The ratio of early mitral diastolic flow velocity obtained with PW Doppler (E) to Em (E/Em) was significantly higher in the diabetic group. According to the mitral valve PW Doppler results, 13.6% of the well-controlled group and 31% of the poorly-controlled group had type 1 diastolic dysfunction. According to the mitral TDI results, 18% of the well-controlled group and 40.4% of poorly-controlled group had type 1 diastolic dysfunction.

CONCLUSIONS

Conventional and TDI echocardiography revealed impairment in left ventricular functions in some patients. Tissue Doppler echocardiography also revealed diastolic impairment in some patients who appeared normal with PW Doppler echocardiography. The present study found that impairment in left ventricular diastolic functions is directly related to glycemic control and the rate of diabetic cardiomyopathy was higher in children with poor metabolic control.

Frequency of the p.Gly262Asp mutation in congenital Factor X deficiency

INTRODUCTION

Congenital factor X (FX) deficiency is a rare bleeding disorder inherited as an autosomal recessive trait with an incidence of 1 : 500 000-1 000 000. A total or partial deficiency of FX causes an impairment of clot formation, leading to a haemorrhagic disease, which manifests with bleeding symptoms of different severity, also unprovoked.

AIM

We analysed the clinical manifestations, laboratory phenotype and genotype in 12 patients from Turkey affected with severe FX deficiency.

METHODS

Prothrombin time (PT), activated partial thromboplastin time (APTT), FX activity (FX:C) and FX antigen level (FX:Ag) were measured, and mutation analysis was performed for all patients.

RESULTS

The most frequent bleeding episodes in patients were epistaxis and easy bruising (11/12, 91%), followed by haemarthroses (10/12, 83%). FX:C was <1% in 11 patients, and 4% in one. FX:Ag was reduced in all patients, consistent with type II deficiency. Direct sequencing of the factor X gene (F10) identified two different mutations: the novel 33 bp in-frame deletion p.Thr176_Gln186, c.526_558del, which seems to be associated with milder bleeding symptoms and the c.785G>A, p.Gly262Asp missense mutation (previously reported as Gly222Asp), which is associated with severe bleeding symptoms.

CONCLUSION

The p.Gly262Asp missense mutation was identified in 11 of the 12 patients in this study. Previously published cases on the same p.Gly262Asp mutation were Iranian patients originating from the border between Turkey and Iran suggesting that this mutation may be candidate as a good tool for mutational screening analysis in this area.

Avian influenza A (H5N1) infection in eastern Turkey in 2006

BACKGROUND

An outbreak of highly pathogenic avian influenza A (H5N1) that had previously been detected throughout Asia, with major economic and health repercussions, extended to eastern Turkey in late December 2005 and early January 2006.

METHODS

We documented the epidemiologic, clinical, and radiologic features of all cases of confirmed H5N1 virus infection in patients who were admitted to Yuzuncu Yil University Hospital in Van, Turkey, between December 31, 2005, and January 10, 2006.

RESULTS

H5N1 virus infection was diagnosed in eight patients. The patients were 5 to 15 years of age, and all eight had a history of close contact with diseased or dead chickens. The mean (+/-SD) time between exposure and the onset of illness was 5.0+/-1.3 days. All the patients had fever, and seven had clinical and radiologic evidence of pneumonia at presentation; four patients died. Results of enzyme-linked immunosorbent assay and rapid influenza tests were negative in all patients, and the diagnosis was made by means of a polymerase-chain-reaction assay.

CONCLUSIONS

H5N1, which causes a spectrum of illnesses in humans, including severe and fatal respiratory disease, can be difficult to diagnose.
