Objectives To evaluate the efficacy and safety of tacrolimus ointment 0.1% in adult and 0.03% in
pediatric patients with moderate to severe atopic dermatitis in Malaysia.
Methods This is an open-labeled and single arm multi-center study. 36 adult and 37 pediatric
patients were enrolled. Tacrolimus ointment is applied twice daily for four weeks. The primary
efficacy outcome is based on the Physician’s Global Evaluation of Clinical Response (PG) at Week
4. The secondary efficacy outcomes are Eczema Area and Severity Index (EASI) score, changes
from baseline in individual scores of signs and symptoms and body surface area affected and
Patients Assessment of Treatment Effects.
Results Overall success rate were 97.1% and 91.2% in the adult and pediatric groups respectively.
The decline in EASI, percentage of total BSA affected and patient’s assessment of pruritus were
significant (P<0.001). Of adults and pediatric patients, 97.2% and 75.7% respectively reported
adverse effect. The most common adverse effect reported was skin burning sensation in 91.7% adult
patients and pruritus in 67.6% pediatric patients.
Conclusion Tacrolimus ointment 0.1% in adult and 0.03% in pediatric patients is effective for the
treatment of moderate to severe atopic dermatitis in Malaysia.

The present study was conducted to investigate the antimicrobial potential of essential oils of Curcuma
longa and Syzygium aromaticum against multidrug-resistant pathogenic bacteria. Four identified
bacterial isolates including Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli, Klebsiella
pneumoniae, and Acinetobacter baumannii were selected and their antibiotic sensitivity was checked
by disc diffusion assay. C. longa and S. aromaticum were subjected to steam distillation to obtain their
essential oils. The crude essential oils were fractioned by employing column chromatography. Crude
essential oils and their fractions were evaluated for their antibacterial activity by agar well diffusion
assay and minimum inhibitory concentrations were calculated. All the selected bacterial isolates
showed resistance to three or more than three antibiotic groups and were declared as multidrugresistant (MDRs). Crude essential oils of C. longa and S. aromaticum exhibited antimicrobial activity
against all selected isolates but S. aromaticum activity was better than the C. longa with a maximum
19.3±1.50 mm zone of inhibition against A. baumannii at 1.04 µL/mL MIC. GC/MS analysis revealed
the abundance of components including eugenol, eugenyl acetate, b- caryophyllene, and a- Humulene
in both crude oil and fractions of S. aromaticum. While the main components of C. longa essential oil
were Ar-tumerone, a–tumerone, b- Tumerone, I-Phellandrene, a-zingibirene, b- sesquiphellandrene,
and p- Cymene. This study highlights that plant-based essential oils could be a promising alternative to
antibiotics for which pathogens have developed resistance. C. longa and S. aromaticum carry compounds
that have antimicrobial potential against multiple drug-resistant bacteria including MRSA. E. coli, K.
pneumoniae and A. baumannii.
