Role of Imaging in Childhood Arthritis.

J Clin Rheumatol 2021 Apr 9. Epub 2021 Apr 9.

Abstract: Imaging plays a pivotal role in the management of various childhood arthritis. Conventional radiography is the most commonly ordered imaging modality for the evaluation of arthritis. Owing to their higher sensitivity for detecting synovitis, magnetic resonance imaging and ultrasonography are increasingly being used to guide clinical management of various forms of arthritis, especially juvenile idiopathic arthritis. Magnetic resonance imaging is a preferred modality for evaluating more complex sites such as the sacroiliac joint. In this review, we have discussed the rational use and the characteristic imaging features of common childhood arthritis.

Diagnostic accuracy of an integrated approach using conventional ultrasonography, and Doppler and strain elastography in the evaluation of superficial soft tissue lesions.

Pol J Radiol 2020 11;85:e293-e300. Epub 2020 Jun 11.

Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India.

Purpose: To assess the diagnostic accuracy of an integrated approach using conventional ultrasonography, colour Doppler ultrasonography, and elastography strain ratios in tandem in the evaluation of superficial soft tissue lesions.

Material And Methods: Sixty-five subjects were included in this prospective cross-sectional study. Greyscale features and Doppler parameters were recorded. Strain elastography of the non-vascular and non-cystic lesions was performed and strain ratios were calculated. Fine-needle aspiration or biopsy of all the lesions was performed depending on their site and condition. Inter-rater k agreement was used to determine the strength of agreement between imaging-based diagnosis and histopathological diagnosis. A diagnostic test was used to calculate the sensitivity, specificity, positive predictive value, and negative predictive value. A p value of < 0.05 was considered statistically significant.

Results: Multiple superficial soft tissue lesions were studied, the majority of which were lipomas, vascular anomalies, and epidermoid cysts. The diagnostic accuracy was very high and varied from 92.31% to 100% for various masses. The imaging-based diagnosis was in agreement with the histopathological diagnosis in 86.15% ( = 56) and disagreement in 13.85% ( = 9) of the cases ( < 0.007). There was very good inter-rater agreement between the imaging-based diagnosis and histopathological diagnosis (κ = 0.818).

Conclusions: The combined use of conventional ultrasonography, colour Doppler, and elastography strain ratios provides a very effective non-invasive tool for the diagnosis of superficial soft tissue lesions and may negate the need for unnecessary biopsies. The advantage of this integrated approach using various ultrasound techniques needs no further emphasis.

Efficacy of Oral Zinc Supplementation in Radiologically Confirmed Pneumonia: Secondary Analysis of a Randomized Controlled Trial.

J Trop Pediatr 2018 04;64(2):110-117

Department of Radiodiagnosis, All India Institute of Medical Sciences, New Delhi 110029, India.

Objective: To evaluate the effect of zinc as an adjuvant therapy in radiologically confirmed pneumonia in children 2-24 months of age.

Patients And Methods: We analyzed data of 212 children with pneumonia for whom chest X-ray films were available at enrollment and at least two radiologists agreed on the diagnosis of pneumonia. We compared the time to recovery in the two groups (n = 121, zinc group and n = 91, placebo group) using a Cox proportional hazards regression model.

Results: Time to recovery was similar in both groups [median interquartile range: zinc, 84 h (64, 140 h); placebo, 85 h (65, 140 h)]. The absolute risk reduction for treatment failure was 5.2% (95% confidence interval: -4.8, 15.1) with zinc supplementation.

Conclusion: There was no significant beneficial effect of zinc on the duration of recovery or risk of treatment failure in children with radiologically confirmed pneumonia.

Tubercular abscess of pons in a child with quadriparesis.

BMJ Case Rep 2010 17;2010. Epub 2010 Mar 17.

Institute of Medical Sciences, Pediatrics, 7FF, Kabir Colony, Bhu, Varanasi, 221005, India.

Tuberculous brain abscess is a rare manifestation of tuberculosis of the central nervous system. We report a case of a 6-year-old girl with a pontine tuberculous abscess, who presented with fever and quadriparesis and recovered completely after stereotactic aspiration and antituberculous treatment with four drugs (isoniazid, rifampicin, pyrazinamide, and ethambutol). Tuberculous abscess was confirmed based on findings of magnetic resonance imaging, a positive tuberculin test, and the presence of acid fast bacilli in smear and culture of abscess aspirate.
