Introduction: Skin is the second most commonly affected organ in SLE. Lupus-specific cutaneous LE(CLE) is classified according to Gilliam Classification into acute CLE (ACLE), subacute CLE(SCLE), chronic CLE(CCLE). CLASI (CLE Disease Activity and Severity Index) is an outcome measures to asses cutaneous activity
Objectives: To study the correlation between cutaneous disease severity and severity of systemic disease using SLEDAI (SLE Disease Severity Index) and SLICC / ACR (Systemic Lupus International Collaborating Clinics) outcome measures.
Methods: Study design: Cross-sectional
A total of 71 patients were recruited from Dermatology and Rheumatology Clinic from Kuala Lumpur Hospital, Selayang
Hospital and Pusat Perubatan UKM. Study period was from December 2009 to August 2010. Study data were obtained
from clinical history, examination, investigations and medical record review.
Results: The mean CLASI activity/damage scores in patients with ACLE, SCLE and CCLE were 11.8 / 8.1, 22.6 / 17.2 and 21.1 / 22.1 respectively. The mean SLEDAI/SLICC scores in similar group of patients were 12.3 / 2.1, 6.8 / 1.6, 13.2 / 1.7 respectively. The cutaneous disease activity in patients with SCLE was found to be inversely correlated to systemic disease activity. The cutaneous damage in patients with CCLE was positively correlated with systemic disease damage
Conclusions: Patients with SCLE, despite having high cutaneous disease activity, had mild systemic disease. Patients with CCLE whom had high cutaneous damage scores were more likely to have higher systemic damage, hence more thorough investigations to seek other organs damage, should be offered.

Objectives This study aims to detect MRSA nasal carriers among medical staff and patients in Dermatology ward Hospital Kuala Lumpur by using two methods, the conventional blood sheep agar (BSA) and the novel BBL CHROMagar MRSA (C-MRSA). It also aims to compare the BSA medium with the C-MRSA medium in terms of specificity, sensitivity and time to detection to MRSA.
Method A single centre, prospective study where 100 nasal swab samples were taken from medical staff and inpatients, then plated on to both BSA and C-MRSA. After 24 hours incubation, the plates were examined for presence of bacterial colonies, then incubated for another
24 hours if no colonies were present. All colonies on C-MRSA and BSA were subjected to coagulase and susceptibility testing for confirmation of MRSA. MRSA strains produce mauve colonies on CMRSA
from hydrolysis of the chromogenic substance, thus C-MRSA
uses colour as a diagnostic tool.
Results Mauve colonies were present on nine C-MRSA plates in the first 24 hours which were all confirmed to be MRSA. Another nine CMRSA plates isolated bluish colonies which were not MRSA. There were colonies on 96 BSA plates, nine of which were MRSA. C-MRSA medium has 100% sensitivity and specificity in detecting MRSA. Both culture media had similar detection rates of MRSA from nasal swabs,
however C-MRSA allows for earlier detection of MRSA within 24 hours compared to BSA which takes 48 hours. 2.2% of ward staff and 15.7% of inpatients were found to be MRSA carriers.
Conclusion CHROMagar MRSA allows for more rapid
identification of MRSA carriers within 24 hours compared to the conventional BSA which takes 48 hours. This allows earlier action to be taken to reduce the spread of MRSA infection.
