RESUMEN

The chitosan nanoparticles because of their biodegradability, biocompatibility,better stability, low toxicity, simple and mild preparation methods, offer a valuable tool tonovel drug delivery systems in the present. The methods such as micro emulsion method,emulsification solvent diffusion method are also in use. The present review describesproperties, different methods of preparation and applications of chitosan nanoparticles

RESUMEN

AIM: To determine whether intravenous ketoprofen is effective as pre-emptive analgesia for breast surgery. DESIGN: Randomised, controlled, double blind study. PATIENTS AND METHODS: 50 patients undergoing breast surgery under general anaesthesia randomised to receive either 100 mg intravenous ketoprofen 30 minutes before (Group I), or immediately after surgical incision (Group II). Postoperatively, pain scores (Visual Analogue Scale, VAS) and time to rescue analgesic were recorded by an independent, blinded observer. The study was terminated when rescue analgesic was required (VAS > or =4 or demand for analgesic). STATISTICAL ANALYSIS: Continuous variables were analysed by the unpaired 't' test, discrete variables with the chi square test, and survival curves by the log-rank test. RESULTS: Pain scores were significantly lower in Group I till 10 hours after surgery. The number of patients requiring analgesia at 4, 6, 8 and 10 hours was significantly lower in group I (0% vs. 47% [P <0.0001], 0% vs. 44% [P <0.003], 0% vs. 80% [P <0.0001], 0% vs. 100% [P <0.0001] respectively). The mean time for rescue analgesic was 15.47 -/+ 2.87 hours in group I versus 4.22 -/+ 2.55 hours in group II (P <0.0001). CONCLUSION: Pre-emptive analgesia with Intravenous ketoprofen (100mg) produces better postoperative pain-relief in patients undergoing breast surgery.

RESUMEN

Learning disabilities (LD) is one of the important causes of poor academic performance in school going children. Learning disabilities are developmental disorders that usually manifest during the period of normal education. These disabilities create a significant gap between the true potential and day to day performance of an individual. Dyslexia, dysgraphia and dyscalculia denote the problem related to reading, writing and mathematics. Perinatal problems are certain neurological conditions, known to be associated with LD; however, genetic predisposition seems to be the most probable etiological factors. Evaluation of a child suspected to be having LD consists of medical examination, vision and hearing test analysis of school performance. The psycho-behaviour assessment and education testing are essential in the process of diagnosis. The experienced persons in the field of LD should interpret the results of such tests. With Individualized Remedial Education Plan (IEP) most children learn to cope up with disability and may get integrated in a regular steam.
