ABSTRACT
To study the incidence and risk factors of the bacteria causing infectious keratitis among patients in Qassim province of Saudi Arabia. This is a cross sectional study conducted at the Department of Optometry, College of Applied Medical Sciences, Qassim University, Qassim, Kingdom of Saudi Arabia from December 2010 to May 2011. One hundred patients suspected of keratitis were subjected to clinical examinations. A total of 115 corneal swabs from these cases were collected under aseptic conditions for bacteriological examinations. Culture of the corneal swabs revealed Pseudomonas aeruginosa [25.2%], Staphylococcus aureus [15.7%], and unclassified bacteria [13.9%]. However, 52 swabs of infectious keratitis cases [45.2%] were negative to bacteria. Contact lens wearing [44.4%] was the most common risk factor among the examined patients, followed by corneal trauma [21.7%], ocular surface disease [11.3%], and corneal surgery [7%]. No significant correlation was observed between systemic risk factor and clinical presentation. It could be concluded that infectious keratitis was mostly due to Pseudomonas aeruginosa and Staphylococcus aureus. Therefore, strict measures are recommended to control and treat infectious keratitis to avoid visual complications

Parathyroid carcinoma is a very rare cause of primary hyperparathyroidism and these tumors are usually hyper-functioning as compared to other malignant endocrine tumors. Surgery is the only effective primary treatment. We report a patient, who presented with pathological fracture of femur, hypercalcemia, bilateral renal stones, markedly raised Parathormone levels and palpable mass in the neck. Parathyroid adenoma was initially diagnosed and localized at left lower gland by Sestamibi scan and ultrasonography. She underwent surgery and enlarged parathyroid gland was removed. Intra operatively there was no evidence of local invasion or lymph nodes involvement but biopsy report suggested malignancy
