Anterior uveitis as a clinical presentation of orbital inflammatory disease in an adult.

We report an unusual case of orbital inflammatory disease presenting as anterior uveitis in an adult. A 35-year-old Chinese man presented with acute anterior uveitis unresponsive to topical steroids, and progressed to manifest optic disc swelling and posterior scleritis. Computed tomography showed a mass-like soft tissue swelling within the intraconal fat indenting the posterior medial aspect of the globe. The diagnosis of orbital inflammatory disease was made, and the patient was treated with systemic corticosteroids with prompt resolution of symptoms and signs. Anterior uveitis can be considered an unusual ophthalmic manifestation of orbital inflammatory disease in adults.

Age-related macular degeneration in Singapore.

INTRODUCTION: This study aimed to describe the morphology of age-related macular degeneration (AMD) as well as to obtain an estimate of the population-based incidence rate in Singapore. METHODS: This is a retrospective hospital-based study of AMD cases seen in 1991 and 1992 at the Singapore National Eye Centre (SNEC), a tertiary eye centre. All case notes recorded with the International Classification of Diseases, ninth revision, clinical modification code '362.5', which is 'degenerations of the macula', were retrieved and analysed. Only case notes of patients who were aged 50 years and above and with documented AMD were included in the study. RESULTS: There were 41 (21.8 percent) patients with drusen alone, 39 (20.7 percent) with dry AMD and 108 (57.5 percent) with exudative AMD. The morphology of the disease was similar among the Chinese and non-Chinese and there were no gender differences. A significant majority of patients with dry and exudative AMD had legal blindness at presentation (p-value is less than 0.0001). Notably, 27 (33.3 percent) patients with exudative AMD had improved vision with time. In comparison, the majority of patients with dry AMD or drusen alone tended to have the same or worsening visual acuity over time. The two-year SNEC hospital incidence rate of AMD in 1991-1992 was 0.38 percent or equivalent to 3.8 per 1,000 new cases seen at SNEC. The estimated population-based incidence rate of exudative AMD was 0.02 percent. CONCLUSION: The population incidence of exudative AMD is lower but comparable to the Western population. Patients with exudative AMD tend to have poorer vision as compared to patients with geographical atrophy or drusen. The proportion of exudative AMD to geographical atrophy appears to be higher than in the West.

Follicular thyroid carcinoma presenting as axial skeletal metastases.

INTRODUCTION: Common modes of presentation of follicular thyroid carcinoma include a solitary thyroid nodule and cervical lymphadenopathy. We report four patients who presented with axial skeletal metastases rather than the usual neck lumps. METHODS: A review of a database of 389 cases of thyroid cancer, managed by our department from 1990 to 2003, was perfomed. Based on each patient's presenting clinical feature, patients for the case series were selected. RESULTS: Four of the 389 patients presented with axial skeletal metastases - three were in the scalp while the fourth was in the sacral region. The histology of all four cases was that of follicular thyroid carcinoma. Despite widespread metastases at presentation, the overall survival rates of these patients remained relatively good. CONCLUSION: Patients presenting with lesions suspicious of secondary malignancy in the axial skeleton should be clinically evaluated for thyroid cancer. This is especially important if the patient belongs to a high risk age group and has highly vascular lesions.

Bipolar clavicular injury.

While clavicular injuries are fairly common, bipolar clavicular injuries are not. They may involve dislocations at both ends of the clavicle, or a fracture at one end and a dislocation at the other. We present two cases; a patient with a bipolar clavicular dislocation, and another with a fracture in both medial and lateral ends of the clavicle with anterior dislocation of the sternoclavicular joint. Both were treated conservatively, with fairly good range of motion and return to normal activity.
