ABSTRACT
Burkitt’s lymphoma (BL), a variety of non-Hodgkin’s lymphoma, is uncommon in India. Cardiac involvement in sporadic BL is rare. Cardiac involvement may be primary or a part of a systemic disease process. It affects the endocardium, myocardium, or pericardium. Cardiac symptoms may or may not be present in the early clinical stages. We are presenting a case of sporadic BL in a 13-year-old child with cardiac and systemic involvement.
ABSTRACT
Although tobacco smoking in Australia is at a historical low, electronic cigarette (e-cigarette) use, especially among the youth is increasing. Policies around e-cigarette control in Australia are currently evolving, even during the pandemic, thus demonstrating its priority status. The current article discusses ethical issues for e-cigarette control policies in Australia using a public health ethics framework. The article is structured using the domains of the WHO-MPOWER framework of tobacco control to enable a comprehensive coverage of all elements of e-cigarette control policies in Australia. It highlights several ethical issues, from different stakeholder perspectives, and indicates moral and ethical tensions in different public health actions that might be considered in framing policies around e-cigarette control. Keywords: Electronic nicotine delivery systems, e-cigarettes, Australia,, smoke-free policy, public health ethics

The kinetic mechanism of glucose dehydrogenase (EC 1.1.1.47) from Halobacterium salinarum was studied by initial velocity and product inhibition methods. The results suggest that both, in the forward and reverse direction, the reaction mechanism is of Bi Bi sequential ordered type involving formation of ternary complexes. NADP+ adds first and NADPH formed dissociates from the enzyme last. For the reverse direction, NADPH adds first and NADP+ leaves last. Product inhibition experiments indicate that (a), the coenzymes compete for the same site and form of the enzyme and (b), ternary abortive complexes of enzyme-NADP(+)-glucono-delta-lactone and enzyme-NADPH-glucose are formed. All the other inhibitions are noncompetitive.

Spasmodic torticollis or cervical dystonia is the commonest focal dystonia. Botulinum toxin-A (BTX-A) was first used in its treatment in 1985. We are reporting our experience of treating 17 patients of cervical dystonia with 29 treatment sessions of BTX-A. The patients consisted of 13 men and four women with a mean age of 44.17 +/- 16.25 years who had tried medical therapy earlier. All patients had a combination of two or more abnormal postures of neck. Both Botox and Dysport were used as per availability. The mean dose of BTX-A in splenius capitus was 283.3 +/- 59.86 U of Dysport and 61.3 +/- 5.16 U of Botox and in sternocleidomastoid it was 210 +/- 53.47 U of Dysport and 46 +/- 18.97 U for Botox. After BTX-A injection, the response was observed after a mean of 9.7 +/- 5.7 days and the mean duration of effect was 15.56 +/- 7.13 weeks. Significant improvement of dystonia (global rating > or = 2) was seen after 25 of 29 treatment sessions (86%) and of pain was seen after four of five patients. Only three treatment sessions were followed by complications (10.4%) of these two had mild dysphagia and one had mild "flu-like" syndrome. We conclude BTX-A is safe and effective treatment of cervical dystonia.

Bilateral striatal necrosis in children without damage elsewhere in the brain can present as an acute neurological disorder or as a progressive disorder. Three children of 6, 7 and 12 years age developed dystonic posture of limbs without any cranial nerve involvement or alteration of sensorium soon after recovery from acute high grade febrile illness of 3-4 days duration. Computerized tomographic scan of head showed bilateral necrosis of basal ganglia. We think that these patients probably constitute a clinically and radiologically distinct subgroup of disorder that produce bilateral striatal necrosis in children. The cause of the syndrome is unknown.
