Spontaneous coronary artery dissection in association with cabergoline therapy.

Spontaneous coronary artery dissection (SCAD) is a rare but increasingly recognised cause of acute coronary syndrome. While numerous risk factors are associated with SCAD, one potential cause is coronary artery vasospasm. The use of cabergoline-an ergot derivative and dopamine agonist that may induce vasospasm-has been associated with SCAD in one other case report worldwide. Here, we describe SCAD in a 37-year-old woman on long-term cabergoline therapy with no other cardiac risk factors. Cabergoline-induced SCAD should be considered in patients presenting with an acute coronary syndrome who are treated with this medication.

Renal allograft loss during transition to adult healthcare services among pediatric renal transplant patients.

BACKGROUND: Transition to adult care occurs at age 18 during a vulnerable adolescent period for pediatric renal transplant (RTx) patients. METHODS: We examined renal allograft loss and hospitalization for RTx biopsy or rejection before and after transition to adult care using clinical and administrative health records of children who underwent RTx (1992-2002) in Ontario, Canada. Life-table analyses examined event rates/100 person years according to age at first RTx. RESULTS: A total of 115 patients were included (57% men; mean age at first transplant 13.9+/-3.7 years). Allograft loss rates were similar across ages 14.0 to 23.9 years. No increase in allograft loss was observed during transition period (ages 18.0-19.9 years). Hospitalizations for RTx rejection or biopsy were much lower after age 18. CONCLUSIONS: Our findings do not support an increased risk of allograft loss after transition to adult care, although there is less hospital use for rejection or biopsy suggesting that differences exist in use of care before complete allograft loss after transition to adult care.

Screening for kidney disease in children on World Kidney Day in Jalisco, Mexico.

World Kidney Day (WKD) is intended to raise awareness and increase detection of chronic kidney disease (CKD), but most emphasis is placed on adults rather than children. We examined yield of screening for CKD and hypertension among poor children in Mexico. On WKD (2006, 2007), children (age < 18 years) without known CKD were invited to participate at two screening stations. We measured body mass index (BMI), blood pressure, and serum creatinine, and performed dipstick urinalysis. The Schwartz equation was used to estimate glomerular filtration rate (GFR; reduced GFR defined as < 60 ml/min per 1.73 m(2)). Proteinuria and hematuria were defined by a reading of >or= 1+ protein or blood on dipstick. Hypertension was defined by gender, age, and height-specific norms. In total, 240 children were screened (mean age 8.9 +/- 4.1 years; 44.2% male). Proteinuria and hematuria were detected in 38 (16.1%) and 41 (17.5%), respectively; 15% had BMI > 95th percentile for age. Reduced GFR was detected in four (1.7%) individuals. Systolic hypertension was more prevalent in younger children (age 0-8 years, 19.6%; age 9-13 years, 7.1%; age 14-17 years, 5.3%) suggesting a possible white-coat effect. Hematuria, proteinuria, hypertension and obesity were frequently detected among children in a community based screening program in Mexico. This form of screening might be useful in identifying children with CKD and hypertension in developing nations.
