ABSTRACT
Chitotriosidase (ChT) is an enzyme that is selectively activated in tissue macrophage. This property of ChT makes it a potential marker for many disease process and prognostication. Present study has been carried out to know the significance of ChT as a screening marker in lysosomal storage disorders (LSDs) where tissue macrophage activation is commonly observed due to accumulation of substrate in various organs of the body. Study comprises of 20 healthy children in the age range of 10 days to 5 yrs and 56 children in the age range of 2.5 months to 13 yrs with regression of milestones, skeletal dysplasia, neuroregression and hepatosplenomegaly were selected for plasma ChT who had confirmed LSDs as carried out by specific lysosomal enzyme study from the leukocytes or fibroblasts. Plasma ChT was 55.21 ± 20.81 nmol/ml /hr in twenty healthy age matched controls. Plamsa ChT level was 42.88 to 79.78 nmol/ml/hr in thirteen of 56 (23.21%) children with LSDs like Morquio- B, Pompe, Metachromatic leucodystrophy (MLD), Sandhoff and Niemann-Pick disease type C (NPD-C). While in 43 (76.78%) children it was in the range of 213.74 to 23,511.40 nmol/ml/hr. who had LSDs like Morquio-B, Sly syndrome, MLD, GM2 Gangliosidosis, NPD-A/B and Gaucher disease (GD). Marked elevated ChT (4,000 to 23,511 nmol/ml/hr) was observed in all cases of GD (n=7) and NDP-A/B. It can be concluded from the present study that moderately raised activity of ChT can be utilized as a positive predictive test for certain LSD’s. Those with marked elevated ChT have confirmed GD or NPD-A/B making it a strong screening marker for this group of diseases.

Medically inappropriate, ineffective and economically inefficient use of antimicrobials is commonly observed in the health care units throughout the world especially in the developing countries. Antimicrobial stewardship programs attempt to balance the demand for these life-saving drugs with the need to preserve their future efficacy. A comprehensive evidence-based stewardship program should include elements chosen from the recommendations based on local antimicrobials use and resistance problems and on available resources that may differ, depending on the size of the institution or clinical setting. For success of antibiotic stewardship it is essential to increase awareness amongst medical professionals. Discipline in antimicrobial prescribing is most vital in clinical settings. A careful assessment of the benefits of prescribing against the risk of non-prescribing of antibiotics should be considered. It should be an endeavor of every physician to justify antibiotic prescription in case of empirical use. Integration of advanced information technology into antimicrobial stewardship programs holds the potential to both reduce antimicrobial overuse and improve outcomes.

Pertussis still continues to cause significant morbidity and mortality worldwide. Because of the high reactogenicity of whole cell pertussis vaccine, it had evoked public controversy in several countries. In 1970 Japan abandoned use of whole cell pertussis vaccine and mounted efforts to develop better vaccine. To date, nearly 24 acellular pertussis vaccines have been developed, using different number and quantity of components. No acellular vaccine is most or least immunogenic with respect to all included antigens. Vaccine efficacy and duration of immunity is comparable with whole cell pertussis vaccine. The adverse events are two thirds less compared to whole cell vaccine.

The usual treatment for empyema in children varies from a simple thoracocentesis to thoracotomy and open decortication. We studied the role of thoracoscopy in the management of empyema thoracis in 10 immunocompetent children after failure of medical management. All children recovered well with an early removal of intercostal tube and reduced postoperative hospital stay and showed complete resolution of empyema on follow up. Thoracoscopy has come as a new ray of hope for the patients with empyema, with the advantages of complete evacuation, minimal pulmonary dysfunction, reduced pain and hospital stay.
