Childhood Absence Epilepsy- Electroclinical Profile and Prevalence of Attention-Deficit/Hyperactivity Disorder Among a Cohort of 47 Children.

BACKGROUND: We aimed to find the proportion of attention-deficit/hyperactivity disorder (ADHD) among children with childhood absence epilepsy (CAE) and to describe their electroclinical features. METHODS: Video electroencephalography (EEG) was performed on 47 children who fulfilled International League Against Epilepsy criteria for CAE. These children were also assessed for the presence of ADHD. RESULTS: Of the 47 children, 27 (57%) met criteria for the diagnosis of ADHD. Majority (74%) of them had inattentive type of ADHD. Age at onset of absences ranged from three to 12 years (mean 7.2 ± 2.47). We analyzed 219 seizures (154 electroclinical and 65 electrographic). The average seizure duration was 7.1 seconds (range 1 to 38 [S.D. 5.81]). Of the 154 clinical absences, ictal discharges were less than or equal to two seconds in nine of 154 (5.8%); greater than two to less than or equal to four seconds in 33 of 154 (21.4%), and longer than 20 seconds in 11 of 154 (7%). The longest duration of ictal discharge recorded was 38 seconds, and the shortest duration was one second. The onset of ictal discharge had a "lead in" focus in 81% (177 of 219). CONCLUSIONS: The proportion of ADHD among children with CAE is high. A "lead in" focus of the generalized ictal discharges was observed frequently, lending support to the theory that the origin of seizure discharges in CAE is indeed cortical. The shortest ictal discharge recorded was one second.

Food allergy in children with asthma and its correlation with level of asthma control.

BACKGROUND: There is paucity of regional data regarding food allergy among children with asthma. OBJECTIVES: To estimate the proportion of children with asthma who have food-related respiratory symptoms and to correlate it with (a) skin prick test (SPT) results and (b) level of asthma control. METHODOLOGY: This cross-sectional study involved children with asthma, aged ≥6 years attending the childhood asthma clinic in a tertiary care hospital, in the southern part of India from July 2017 to July 2019. Basic demography and clinical details were recorded. In subjects with a history of food allergy, skin prick test (SPT) was done using AllergoSPT according to guidelines recommended by British Society of Allergy and Clinical Immunology (BSACI). Asthma control was assessed using asthma control test (ACT) and childhood ACT questionnaires. RESULTS: Of the total 305 children included, the most commonly reported allergen was banana (45%, n = 137). The predominant symptom reported was wheezing (54%). SPT was positive in 76 children (24.9%). Level of asthma control (P value < .01), family history of atopy (P value < .01), and age at introduction of complementary foods (P value < .01) were significantly associated with food allergy. CONCLUSION: Presumed food allergy is seen in one-fourth of children with asthma and significantly affects symptom control in them.

A comprehensive molecular study identified 12 complementation groups with 56 novel FANC gene variants in Indian Fanconi anemia subjects.

Fanconi anemia (FA) is a rare autosomal or X-linked genetic disorder characterized by chromosomal breakages, congenital abnormalities, bone marrow failure (BMF), and cancer. There has been a discovery of 22 FANC genes known to be involved in the FA pathway. This wide number of pathway components makes molecular diagnosis challenging for FA. We present here the most comprehensive molecular diagnosis of FA subjects from India. We observed a high frequency (4.42 ± 1.5 breaks/metaphase) of chromosomal breakages in 181 FA subjects. The major clinical abnormalities observed were skin pigmentation (70.2%), short stature (46.4%), and skeletal abnormalities (43.1%), along with a few minor clinical abnormalities. The combination of Sanger sequencing and Next Generation Sequencing could molecularly characterize 164 (90.6%) FA patients and identified 12 different complementation groups [FANCA (56.10%), FANCG (16.46%), FANCL (12.80%), FANCD2 (4.88%), FANCJ (2.44%), FANCE (1.22%), FANCF (1.22%), FANCI (1.22%), FANCN (1.22%), FANCC (1.22%), FANCD1 (0.61%) and FANCB (0.61%)]. A total of 56 novel variants were identified in our cohort, including a hotspot variant: a deletion of exon 27 in the FANCA gene and a nonsense variant at c.787 C>T in the FANCG gene. Our comprehensive molecular findings can aid in the stratification of molecular investigation in the diagnosis and management of FA patients.

An Unusual Presentation of Recurrent Childhood Kimura Disease: Ileocecal Involvement.

Kimura disease commonly presents as an isolated swelling over the head and neck region. Intestinal involvement by Kimura disease in children is uncommonly reported. We report a 10-year-old boy who had presented with an ileocaecal mass with peripheral blood eosinophilia and elevated immunoglobulin E levels. The histopathologic examination from the ileocaecal mass was suggestive of Kimura disease. He had 2 recurrences once in the left axillary region and once in the bilateral cervical region. Ileocaecal involvement in Kimura disease is an uncommon presentation in childhood. Careful evaluation of complete blood count is critical in making diagnosis and avoiding unnecessary invasive procedures.
