Aloe barbadensis miller or Aloe vera has been used for therapeutic purposes since ancient times with antifungal activity known to be amongst its medicinal properties. We conducted a pilot study to determine the antifungal properties of Malaysian Aloe vera leaf extract on otomycosis species including Aspergillus niger and Candida albicans. This laboratory-controlled prospective study was conducted at the Universiti Sains Malaysia. Extracts of Malaysian Aloe vera leaf was prepared in ethanol and solutions via the Soxhlet extraction method. Sabouraud dextrose agar cultured with the two fungal isolates were inoculated with the five different concentrations of each extract (50 g/mL, 25 g/mL, 12.5 g/mL, 6.25 g/mL, and 3.125 g/mL) using the well-diffusion method. Zone of inhibition was measured followed by minimum inhibitory concentration (MIC). For A. niger, a zone of inhibition for alcohol and aqueous extract was seen for all concentrations except 3.125 g/mL. There was no zone of inhibition for both alcohol and aqueous extracts of Aloe vera leaf for C. albicans. The MIC values of aqueous and alcohol extracts were 5.1 g/mL and 4.4 g/mL for A. niger and since no zone of inhibition was obtained for C. albicans the MIC was not determined. The antifungal effect of alcohol extracts of Malaysian Aloe vera leaf is better than the aqueous extract for A. niger (p < 0.001). Malaysian Aloe vera has a significant antifungal effect towards A. niger.

Foreign body (FB) ingestion is very common in Malaysian population. The most commonly ingested FB is fish bone. Common presenting symptoms include FB sensation, odynophagia and or sharp pricking pain during swallowing. A careful history and physical examination is very important. Despite negative laryngoscopy and rigid esophagoscopy, persistent symptoms warrants further radiographic imaging studies. The FB can migrate extraluminally and involve other important adjacent structures of the neck and along the digestive tract. We report 3 cases of extraluminal migration of fish bone and their complications, which were successfully managed. One case with vascular complication which involve common carotid artery and the other two cases with neck abscess formation involving thyroid gland, retropharyngeal and parapharyngeal abscess.

During the first phase of the Movement Control Order, many medical lecturers had difficulty adapting to the online teaching and learning methods that were made compulsory by the institutional directives. Some of these lecturers are clinicians who need to juggle between clinical work and teaching, and consider a two-week adaptation during this period to be not enough. Furthermore, converting traditional face-to-face learning to online formats for undergraduate and postgraduate clinical programmes would reduce the learning outcomes, especially those related to clinical applications and the acquisition of new skills. This editorial discusses the impact that movement restrictions have had on medical teaching and learning, the alternatives and challenges and the way forward.

The human orbit is a complex anatomic region, which plays predominant role in the evaluation of craniofacial complex. A thorough understanding of the relationship of the distance from orbital rim to the important vital structures of the orbital apex is required for the surgeon to perform safe and effective surgery. To evaluate and compare the depth and distances from various points of the orbital rim to the fissures and foramina of the orbital apex between genders in the local population. Linear measurements were conducted on 60 orbits from 30 patients who had undergone head computed tomography scan. These measurements were done utilizing the multiplanar reconstruction modes on computed tomography images with minimum slice thickness of 1 mm. Males have statistically significant larger orbits than females with higher mean measurements in all parameters, except for the distance from posterior ethmoidal foramen to the optic canal which was the same. However, there were no significant differences in all parameters between the right and left orbits. This study provides the absolute limit of safe internal orbital dissection in respect to the local population. Despite males having larger orbits than females, it is clinically negligible.

Sialolithiasis is the formation of calculi or sialoliths in the salivary gland. It is the most common benign condition of the salivary gland. Sialolithiasis can occur in all salivary glands. The submandibular gland is most commonly affected followed by the parotid gland. Calculi commonly measure less than 10 mm. Calculi of more than 15 mm are termed giant salivary gland calculi and are infrequently reported in the literature. Here, we report a case of unusually large submandibular gland calculus of 5 cm in greatest dimension which caused erosion of the oral cavity.
