Trichilemmal cyst nevus with a sebaceous nevus component

A 23-year-old man with a typical trichilemmal cyst nevus is reported. This recently described disorder is sufficiently characteristic to differentiate it from sebaceous nevus, nevus comedonicus, porokeratotic eccrine nevus, nevus corniculatus, follicular basaloid hamartoma, Munro's nevus and Gardner's syndrome.

Dialysis and Renal Transplantation in HIV-Infected Patients: a European Survey

OBJECTIVES:: To determine prevalence and characteristics of end-stage renal diseases (ESRD) [dialysis and renal transplantation (RT)] among European HIV-infected patients. METHODS:: Cross-sectional multicenter survey of EuroSIDA clinics during 2008. RESULTS:: Prevalence of ESRD was 0.5%. Of 122 patients with ESRD 96 were on dialysis and 26 had received a RT. Median age was 47 years, 73% were males and 43% were black. Median duration of HIV infection was 11 years. Thirty-three percent had prior AIDS; 91% were receiving antiretrovirals; and 88% had undetectable viral load. Median CD4T-cell count was 341 cells per cubic millimetre; 20.5% had hepatitis C coinfection. Most frequent causes of ESRD were HIV-associated nephropathy (46%) and other glomerulonephritis (28%). Hemodialysis (93%) was the most common dialysis modality; 34% of patients were on the RT waiting list. A poor HIV control was the reason for exclusion from RT waiting list in 22.4% of cases. All the RT recipients were all alive at the time of the survey. Acute rejection was reported in 8 patients (30%). Functioning graft was present in 21 (80%). CONCLUSIONS:: This is the first multinational cross-sectional study of ESRD among European HIV population. Low prevalence of ESRD was found. Two-thirds of patients were excluded from RT for non-HIV/AIDS-related pathologies. Most patients had a functioning graft despite a high acute rejection rate.

Gout in pediatric renal transplant recipients

Clinical gout has rarely been described after pediatric renal transplantation (RTx), although asymptomatic hyperuricemia is common in these patients. We describe three male pediatric patients who presented with gouty arthritis 7-8.5 years following RTx. Since receiving allopurinol, all patients had been free of gouty symptoms. To prevent severe bone marrow depletion, the dosage of azathioprine, an immunosupressant drug, was reduced by 50% to prevent interaction with allopurinol. Because atypical presentation of gout can occur, a high index of suspicion is needed to allow appropriate diagnosis of this disease in patients with skeletal pain after RTx.
