Intracranial arachnoid cysts and epilepsy in children: Should this be treated surgically? Our 29-year experience and review of the literature

INTRODUCTION AND OBJECTIVE

Arachnoid cysts (ACs) are relatively frequent lesions related to different neurological symptoms, being mostly incidentally diagnosed. This study aims to clarify whether AC surgery in epileptic patients is useful in their treatment.

MATERIAL AND METHODS

The patients registered in the database of the Neuropediatrics Section from May 1990 to August 2019 are analyzed retrospectively. Patients in whom the diagnosis of ACs and epilepsy coincide are studied. The location, size and number of ACs, neurological development, age at diagnosis, follow-up time, the performance of surgery on the cyst, evolution, anatomical relationship between brain electrical activity and location of AC, and type of epilepsy are analyzed.

RESULTS

After analyzing the database, we found 1881 patients diagnosed with epilepsy, of which 25 had at least one intracranial AC. In 9 of the patients, cerebral or genetic pathologies were the cause of epilepsy. Of the other 16, only 2 patients showed that the type of epilepsy and the epileptogenic focus coincided with the location of the AC; one of them was surgically treated without success, and the other one remained asymptomatic without receiving medical or surgical treatment.

CONCLUSIONS

Although it is necessary to design a prospective study to establish causality, the results of our research and the available literature suggest that there is no causal relationship between the presence of ACs and epilepsy. The study and treatment of these patients should be carried out in a multidisciplinary epilepsy surgery unit, without initially assuming that the AC is the cause of epilepsy.

Evolution of strain and strain rate values throughout gestation in healthy fetuses

Myocardial deformation by speckle tracking echocardiography is a novel method for evaluating cardiac function. To test the hypothesis that right ventricular and left ventricular function have age-specific patterns of development, we tracked the evolution of ventricular strain mechanics by speckle tracking echocardiography in the fetus. We conducted a retrospective cross sectional echocardiography study in 154 healthy fetuses, and characterized cardiac function by measuring right and left ventricles global longitudinal strain and strain rate. Comparison of the data of both ventricles according to gestational age was carried out. The magnitudes of right and left ventricle global longitudinal strain show wide range values and decreased throughout gestation. Strain values are higher in left ventricle compared to the right one throughout pregnancy. Strain rate values were similar over gestation in each ventricle, but the magnitudes declined overtime in the right and left ventricle. The maturational patterns of left and right strain are gestational specific. With accepted physiological maturation patterns in healthy subjects, these myocardial deformation parameters can provide a valid basis that allows comparison between health and disease.

Quality of life and chronic health conditions in childhood acute leukaemia survivors

BACKGROUND

Survival of childhood acute lymphoblastic leukaemia involves an increasing risk of long-term morbidities. Due to the impact of cancer treatment and comorbidities, AL survivors may experience a decrease in their health-related quality of life.

OBJECTIVE

We aimed to describe the long-term comorbidities, related quality of life and their development predictors in these survivors.

METHODS

cross-sectional study of 54 survivors aged ≥18 and who have a survival rate of more than 10 years. Quality of life was assessed by personal interview using SF-36 questionnaire.

RESULTS

53.7% of AL survivors developed more than one comorbidity (24.7% hypothyroidism; 20.3% obesity; 14.8% metabolic syndrome; 18.5% subclinical cardiac dysfunction); 20.3% of them were severe. 73.3% of high-risk leukaemias and 66.6% of patients treated with radiotherapy or stem cells transplantation reported long-term comorbidity, P<.05. Global quality of live score was: 86.3 (14) (classified as very good). Patients with high-risk acute leukaemia (83.2 vs. 89.5), severe long-term comorbidities (80.4 vs. 89.7) and females (81.8 vs. 89.9), reported worse quality of life, P<.05. Physical summary score was worse in: obese (80 vs. 92) and hypothyroid (84.9 vs. 92.4) and radiotherapy-treated survivors (82.3 vs. 87.5); mental summary was worse in survivors with hypogonadism (68.2 vs. 86.3) and trasplanted patients (77.2 vs. 83.1), P<.05.

CONCLUSIONS

Acute leukaemia survivors reported an increase prevalence of chronic comorbidities, related to cancer-treatment. Despite a decrease in scores for certain physical or mental items, global quality of life was very good in all acute leukaemia survivors, even better than compared with the general population.

[Effects of growth hormone treatment on anthropometrics, metabolic risk, and body composition variables in small for gestational age patients]

INTRODUCTION AND OBJECTIVES

Small for gestational age (SGA) children without catch-up growth can benefit from treatment with growth hormone (rhGH). However, they should be monitored very closely because they are at increased risk of metabolic syndrome.

MATERIAL AND METHOD

A group of 28 SGA children with a mean age of 8.79 years and undergoing treatment with rhGH were selected for evaluation. Over the course of 4 years, an annual evaluation was performed on the anthropometric variables (weight, height, body mass index [BMI], growth rate, blood pressure and waist perimeter), metabolic risk variables (glycaemia, glycosylated haemoglobin, cholesterol ratio, insulinaemia, insulin-like growth factor 1[IGF1], IGF binding protein-3 [IGFBP-3], IGF1/IGFBP3 ratio, and HOMA index), and body composition variables.

RESULTS

Treatment with rhGH was associated with a significant increase in height (-2.76±.11 SD to -1.53±.17 SD, P=.000), weight (-1.50±.09 SD to -1.21±.13 SD; P=.016), and growth rate (-1.43±.35 SD to .41±.41 SD; P=.009), without a corresponding change in the BMI. Insulinaemia (9.33±1.93mU/ml to 16.55±1.72mU/ml; P=.044) and the HOMA index (3.63±.76 to 6.43±.67; P=.042) increased, approaching insulin resistance levels. No changes were observed in the lipid profile. Body composition changes were observed, with a significant increase in lean mass (73.19±1.26 to 78.74±1.31; P=.037), and a reduction of fat mass (26.81±1.26 to 21.26±1.31; P=.021).

CONCLUSION

Treatment with rhGH is effective for improving anthropometric variables in SGA patients who have not experienced a catch-up growth. It also produces changes in body composition, which may lead to a reduction in risk of metabolic syndrome. However, some insulin resistance was observed. It is important to follow up this patient group in order to find out whether these changes persist into adulthood.
