PURPOSE: To report the clinical profile of 34 ocular TB cases observed during 6 years period in Hospital Universiti Sains Malaysia (HUSM).
METHOD: A retrospective review of medical records from 34 patients diagnosed with ocular TB in HUSM from January 2011 until December 2016.
RESULTS: The mean age was 43 ± 14.6 years old. Both male and female affected in about 1:1 ratio. The majority of subjects were local Malays (91.2%). Risk factors included previous contact with pulmonary TB patients (38.2%), and patients with underlying diabetes mellitus (26.5%). Most patients showed normal chest radiography (79.4%). However they had positive Mantoux test (94.1%) and raised erythrocyte sedimentation rate (ESR) value (58.8%). Uveitis was the most common ocular manifestation of ocular TB (70.6%) while the rare ocular manifestations included optic perineuritis and optic neuritis, orbital apex syndrome, orbital cellulitis, sclerokeratitis, corneal ulcer and conjunctival abscess. All patients responded well to anti-TB treatment, but visual outcome was variable.
CONCLUSIONS: This review shows the diverse entity of ocular TB spectrum in an endemic area. Good clinical response to anti-tuberculous therapy supported the presumed diagnosis of ocular TB in majority of the cases.
AIM: In this study, maceration and Soxhlet extraction of the whole plant of Cassia alata Linn. (leaves, roots, and stem) were performed using four solvents with different polarities, namely n-hexane, ethyl acetate, ethanol and distilled water. The crude extracts were screened using agar well diffusion, colorimetric broth microdilution, grid culture and bacterial growth curve analysis against Staphylococcus aureus. The phytochemicals in the crude extracts were identified using Gas Chromatography-Mass Spectrometry (GC-MS).
RESULTS: Agar-well diffusion analysis revealed that extraction using ethyl acetate showed the largest inhibition zone with an average diameter of 15.30 mm (root Soxhlet extract) followed by 14.70 mm (leaf Soxhlet extract) and 13.70 mm (root maceration extract). The lowest minimum inhibitory and minimum bactericidal concentration in root Soxhlet extract using ethyl acetate was 0.313 and 0.625 µg µL-1, respectively. Our study proved that crude extract of the plant suppressed the growth of S. aureus as evidenced from a significant regression extension (p
