ABSTRACT
Objective: To assess proportion and predictors of lesion calcification in children aged 2-12 years with neurocysticercosis at six months follow up. Method: Children aged between 2 and 12 years with Neurocysticercosis diagnosed on MRI brain were initially included and followed up for 6 months. Repeat CECT brain at 6 months was done to find if the lesion persisted/calcified/ resolved. Results: 16 out of 30 patients (53.3%) had calcification at six months follow up. Perilesional edema at the initial stage of the presentation was significantly associated with calcification at 6 months (P=0.042). Conclusion: Perilesional edema at the time of presentation was significantly associated with calcification in children with neurocysticercosis, six months after diagnosis.
ABSTRACT
Background: The role of heavy metals in the etio-pathogenesis of attention deficit hyperactivity disorder (ADHD) is a burning enigma. The available studies with discordant results are from different geographical localities with different monitoring, regulations and sociocultural backgrounds. The differential association of heavy metals with ADHD severity and phenotypes has not been adequately examined. Also, there are concerns about laboratory quality control. Therefore, the present case control study was formulated.Methods: Thirty children with ADHD diagnosed by DSM IV criteria and thirty group age matched controls were enrolled. Detailed perinatal, past, developmental and possible exposure history to various heavy metals was taken. Severity of ADHD was assessed using ConnersTM Parent reporting questionnaire. Blood level of metals was estimated by inductively coupled plasma- atomic emission spectroscopy (ICP-AES).Results: The mean blood lead, mercury, cadmium, arsenic, zinc were comparable in children with ADHD and group age matched controls. The mean blood lead, mercury and cadmium levels in study population was higher than found in studies from developed countries. Elevated arsenic, mercury and cadmium were found in both cases and controls. Blood zinc correlated significantly with inattention T score and blood mercury with hyperactivity-impulsitivity T score of Conners parent rating scale. Blood cadmium was present in greater proportion of predominant hyperactive-impulsive type patients.Conclusions: Zinc deficiency correlates with inattention; cadmium and mercury toxicity correlate with hyperactivity. Mean blood levels of heavy metals is elevated in a substantial proportion of study population. So, there is an urgent need for sensitization and environmental control.
ABSTRACT
Hereditary myoclonus dystonia is a rare movement disorder characterized with combination of myoclonic jerks with mild to moderate dystonia. Mostly caused due to changes in SGCE gene. Author report case of a 3 years old girl with atypical features of lower limb onset, mild dystonia, upper limb and neck myoclonic jerks and younger onset. She was detected to have pathogenic variant of SGCE gene. A diagnosis of myoclonus dystonia should be considered at an early age also like in our case so that treatment is initiated early for better results and improved quality of life and development.
