Prevalence and determinants of retinopathy in a cohort of Lebanese type II diabetic patients.

Objective: Our aim was to determine the prevalence and the risk factors for diabetic retinopathy (DR) in a cohort of type II diabetic patients in Lebanon.

Design: Prospective observational cohort study.

Participants: Five hundred consecutive patients with type II diabetes mellitus followed at the American University of Beirut Medical Center diabetes clinic were enrolled in the study.

An unusual case of autonomous hyperparathyroidism in a patient with X-linked hypophosphatemic rickets and Kallmann syndrome.

We are reporting an unusual patient who presented to our medical center at 18 years of age for evaluation of disabling bilateral lower extremity deformity and delayed puberty. Extensive clinical, laboratory, and radiologic evaluation confirmed the coexistence of 2 X-linked inherited disorders, X-linked hypophosphatemic rickets (XLH) and Kallmann syndrome (KS). Treatment with oral phosphate and calcitriol along with intramuscular testosterone injections was initiated.

The association of Hashimoto disease and Congo red negative amyloidosis.

Systemic amyloidosis which is characterized by extracellular deposition of monoclonal immunoglobulin light chains in various organs may be difficult to diagnose at an early stage, especially when the Congo red stain is negative. We describe herein a case of Congo red negative primary amyloidosis associated with Hashimoto thyroiditis. The patient presented with multiple organ involvement suggestive of amyloidosis including heart failure, renal failure, and macroglossia.
