ABSTRACT
INTRODUCTION: Cutaneous abscess incision and drainage and foreign body removal are 2 common procedures in a variety of outpatient settings. The goal of this project was to create a novel, clean, reusable task trainer that could more accurately reproduce all the steps necessary to perform cutaneous abscess drainage or foreign body removal including ultrasound to identify the abscess cavity or foreign body. METHODS: The novel task trainer was constructed using silicone for both the base and the top skin. Toothpaste mixed with saline was used for the abscess material as this produced an ultrasound image that mimicked purulent material. A piece of a metal paper clip was imbedded in the top skin to mimic a cutaneous foreign body. Physician assistant (PA) students given a didactic lecture then used the novel task trainer as part of a clinical skills course. RESULTS: After the activity, the PA students were asked to voluntarily complete a brief preretrospective/postretrospective survey comprised 8 questions that addressed their self-perceived knowledge and skills using a 5-point Likert scale. Survey data from an initial cohort of PA students at one university show effectiveness of the models when used with the associated curriculum. DISCUSSION: This study demonstrates the feasibility of constructing a practical, low-cost, non-animal-based task trainer for the purpose of training incision and drainage of cutaneous abscesses and removal of cutaneous foreign bodies. This novel task trainer allows for ultrasound skill development and provides realistic imaging experience.

Synesthesia is an unusual condition in which stimulation of one sensory modality causes an experience in another sensory modality or when a sensation in one sensory modality causes another sensation within the same modality. We describe a previously unreported association of auditory-olfactory synesthesia coexisting with auditory-visual synesthesia. Given that many types of synesthesias involve vision, it is important that the clinician provide these patients with the necessary information and support that is available.

The first case of central serous chorioretinopathy secondary to blunt trauma is presented. Optical coherence tomography performed on presentation, 3 days after trauma, demonstrated a neurosensory detachment of the macular, thus confirming clinical findings. At 3 months after injury, the retina had spontaneously flattened at the macular and vision had returned to normal.
ABSTRACT
OBJECTIVE: The aim of this study was to report a case of Charles Bonnet syndrome secondary to eye patching following eyelid reconstruction with an unusually acute onset. METHOD: An observational case report was conducted. RESULTS: The patient reported complex visual hallucinations that started less than 10 minutes after patching of her right eye (the left eye had poor vision from previous trauma). The patch was removed after 2 days, and the hallucinations gradually stopped over the subsequent 2 days. CONCLUSION: This case of Charles Bonnet syndrome describes an unusually acute onset of hallucinations and is only the second reported case following eye patching. Eye patching is commonly used in a number of situations, and it is important to be aware of this association, as the diagnosis of Charles Bonnet syndrome is often overlooked.

The authors present a case of Behçet disease presenting with frosted branch angiitis. Frosted branch angiitis is a rare clinical finding and there are only two reported cases in the literature associated with Behçet disease.

PURPOSE: To compare the diurnal intraocular pressure (IOP) profile pre and post trabeculectomy with a control group of medically controlled patients. We compared the change in mean, peak, and diurnal IOP fluctuation. METHODS: This was an observational study of patients at the Bristol Eye Hospital, United Kingdom. All patients underwent initial and subsequent phasing, with surgery between for cases. The unpaired Student t test compared the changes (initial-subsequent) in mean, peak, and fluctuation between cases and controls. RESULTS: Fifteen eyes underwent trabeculectomy surgery while the control group contained 17 eyes controlled on topical medical treatment. There was a statistically significant reduction in both mean IOP of 3.7 mmHg (p=0.002) and peak IOP of 4.4 mmHg (p=0.025) in the surgical group compared to the medical group. There was no statistically significant change in the IOP fluctuation between the 2 study groups (p=0.296). CONCLUSIONS: There is a significant reduction in mean IOP and peak IOP following trabeculectomy. We showed no statistically significant change in the diurnal fluctuation of IOP following trabeculectomy.
