Comparative StudyDifferences between males and females in adult sickle cell pain crisis in eastern Saudi Arabia.
Sickle cell disease (SCD) is highly prevalent in the Al-Hasa area of eastern Saudi Arabia. We analyzed our patient data to try and find an explanation for the unexpected observation that more males than females with SCD were transferred to the hospital after a stay in the stabilization unit. ⋯ These preliminary observations point to the need for further studies into gender differences in pain crisis in patients with SCD.

Plasma homocysteine and retinal artery occlusive disease: a case-control study.
Previous studies have documented that elevated plasma homocysteine is a risk factor for cardiovascular, cerebrovascular and peripheral vascular disease. In a case-control study, we sought to determine whether elevated homocysteine (HCY) is a risk factor for retinal artery occlusive disease PATIENTS AND METHODS. Study subjects consisted of 20 patients (12 male, 8 female) (mean age, 55.8; range 42-70 years) with clinical and objective evidence of retinal vascular occlusive disease and 20 age-matched control subjects (9 males, 11 females) (mean age, 55.3 years; range 50-68 years). Hyperhomocysteinemia was defined as a plasma HCY level >15 micromol/L by HPLC. We also measured concentrations of triglycerides, and total cholesterol, LDL cholesterol, and HDL cholesterol. ⋯ The mean plasma HCY level in the patient group was 21.23+/-9.53 micromol/L (range, 8.00-43.99 micromol/L) compared with 12.59+/-4.97 micromol/L (range, 6.38 to 22.88 micromol/L) in the control group (P<0.008). There was no correlation between HCY and serum triglycerides or cholesterol levels within each group. We conclude that high plasma HCY level may be a risk factor for retinal artery occlusive disease.
