·AIM: To present a case of Coats' disease in adult and to illustrate the retinal findings.·METHODS: A case report.·RESULTS: A 63 years old Malay man, a known case of diabetes mellitus, presented with one year history of painless and progressive reduced vision in the right eye. Right eye visual acuity was counting finger 2 feet while left eye best corrected visual acuity was 6/12. Right fundus showed presence of extensive subretinal exudates at the temporal part of the posterior pole involving the macular area and nasal to the optic disc. It was associated with multiple areas of abnormal blood vessels temporal to the macula with attenuated vessels. Fundus fluorescein angiography(FFA) showed presence of telangiectatic vessels at the area of subretinal exudates and leakage of fluorescein from the telangiectatic vessels. The left eye was normal. Based on clinical and FFA findings, he was diagnosed to have adult Coats' disease. The right eye was treated with argon laser photocoagulation. Six months post laser, his visual acuity remained at 6/120 and there was minimal regression of the disease seen in the retina. ·CONCLUSION: The clinical and angiographic findings are important in diagnosing retinal telangiectasia. Treatment by laser photocoagulation in area of leakages may be beneficial in preventing visual loss.

Branchial apparatus anomalies usually manifest in teenage or early adult life. Infection complicates second branchial pouch anomalies usually presented as a neck lump or discharging sinus. It is the most common form of anomalies compared to another branchial pouch aberrant. However, it is extremely rare to find a complete branchial fistula with both internal and external openings. Misdiagnosis usually occurs leading to inappropriate and suboptimal treatment. Here, we report of a case of complete second branchial pouch fistula and discuss the clinical presentation and surgical management of such lesion.

Aims:
The antibiofilm activity of endophytic fungus Nigrospora sphaerica CL-OP30 isolated from Swietenia macrophylla King was investigated.
Methodology and results:
The ability of the fungal endophytic crude extract to impede Streptococcus mutans biofilm formation was preliminarily screened with Congo red agar test. It was proven that S. mutans biofilm formation was hindered on the agar supplemented with the fungal endophytic crude extract. The antibiofilm activity of the fungal endophytic crude extract was evaluated using a microtiter plate method on both initially formed and preformed biofilm. Antibiofilm activity was recorded in a concentration-dependent pattern whereby higher concentrations reduced biofilm formation better than the lower concentrations of extract for both initially formed and preformed biofilm. The architecture of biofilm tested with fungal endophytic crude extract was also observed. Visualization under a light microscope and SEM revealed that the adherence of S. mutans biofilm treated with fungal endophytic crude extract was significantly
reduced in both initially formed and preformed biofilm. In addition, observation under SEM showed that the matrices surrounding the bacterial cells were disintegrated and bacterial cells in biofilm completely lost their original shape. The overall data demonstrated that the ethyl acetate N. spaherica CL-OP30 crude extract showed good antibiofilm activity.
Conclusion, significance and impact of study
The antibiofilm study suggested the potential of N. sphaerica CL-OP30 crude extract against S. mutans biofilm by disrupting the biofilm formation, the disintegration of matrices surrounding the biofilm and responsible for the formation of irregular cell shape. This extract may have a promising potential to be
developed as an antibiofilm agent.
