MATERIALS AND METHODS: The detection of inducible clindamycin resistance was performed by D-test using erythromycin and clindamycin discs as per CDC guidelines.

RESULTS: Among the 244 clinical isolates of staphylococci studied, 32 (13.1%) showed inducible clindamycin resistance and belonged to the MLSBi phenotype. Among the MLS B i phenotypes, 10 isolates were methicillin-resistant Staphylococcus aureus (38.4% of the total MRSA), 16 were methicillin-sensitive Staphylococcus aureus (12.9% of the total MSSA) and 6 were coagulase-negative staphylococci (6.3% of the total CONS).

MATERIALS AND METHODS: A prospective cohort study involving 240 patients undergoing mobile-bearing medial UKA was conducted. Group A (na=80) received postoperative correction of Vitamin D3 Deficiency (VDD), Group B (nb=80) received pre-operative correction of VDD, while Group C (nc=80) had normal Vitamin D3 levels to begin with (≥30ng/ml). Correction was done by three doses of intramuscular injection of 600,000 IU Arachitol® (Vitamin D3) given at an interval of one week each. All groups were matched for demography and outcome measures. The level of bone pain by checking for tibial shin tenderness quantified by the visual analog scale (VAS) and evaluated pre-operatively, and at 2, 4, 6 and 12 weeks post-operatively.

RESULTS: Group B and C showed similar post-operative trends and remained significantly superior to Group A till the 6th-week follow-up. The biostatistical difference between Group A and the other two groups started decreasing after the completion of post-operative correction regime as noticed on the 6th-week follow-up. By 12 weeks post-operatively, all three groups had similar levels of bone pain.
