    Henoch-Schonlein purpura, post-streptococcal glomerulonephritis and acute rheumatic carditis after Group A β-haemolytic streptococcal infection
    Çamlar, SA; Soylu, A; Akil, I; Ünlü, M; Coskun, S; Ertan, P; Kavukçu, S
    Besides association with acute rheumatic fever (ARF) and acute glomerulonephritis (APSGN), in up to 40% of cases, Group A beta-haemolytic streptococcal (GABHS) infections are also implicated as a trigger for Henoch-Schonlein purpura (HSP). A 7-year-old girl with GABHS throat infection who developed HSP, APSGN and rheumatic carditis is reported. She presented with palpable purpura and arthritis in both ankles and later developed carditis characterised by mitral/aortic regurgitation and glomerulonephritis characterised by mixed nephritic/nephrotic syndrome. She had a raised anti-streptolysin titre (ASOT), blood urea nitrogen and creatinine and hypocomplementaemia (C-3), and renal biopsy demonstrated endocapillary and extracapillary proliferative glomerulonephritis with crescents. Immunofluorescence microscopy demonstrated a full house' of immunoglobulin and complement, viz. IgA+2, IgG+3, IgM+2, C(3)c+1, Clq+2 with predominantly IgG deposition. One week earlier, her 4-year-old sister had presented to another hospital with HSP complicated by microscopic haematuria, nephrotic-range proteinuria and gastro-intestinal involvement, and with raised ASOT and low C-3 levels. Although HSP has been associated with either ARF or APSGN, this is the first case of a child with HSP, ARF and APSGN in combination.

    Renovascular disease accounts for 8-10% of all cases of paediatric hypertension, whereas, in adults, its incidence is approximately 1%. The Turkish Paediatric Hypertension Group aimed to create the first registry database for childhood renovascular hypertension in Turkey. Twenty of the 28 paediatric nephrology centres in Turkey responded to the survey and reported 45 patients (27 girls, 18 boys) with renovascular hypertension between 1990 and 2005. The age at presentation ranged from 20 days to 17 years. The mean blood pressure at the diagnosis was 169/110 mmHg. Chief complaints of symptomatic patients were headache (38%), seizure (18%), epistaxis (4%), growth retardation (4%), cognitive dysfunction (4%), polyuria (2%), palpitation (2%), and hemiplegia (2%). Renovascular hypertension was found incidentally in 11 children. The diagnosis of renovascular hypertension was established with conventional angiography in 39 patients, MR angiography in three, CT angiography in two, and captopril diethylene triamine penta-acetic acid (DTPA) scintigraphy in one patient. Twenty-one children had bilateral renal artery stenosis and 24 had unilateral renal artery stenosis. Of these, 14 (31%) had fibromuscular dysplasia; 12 (27%) Takayasu's arteritis; six (13%) neurofibromatosis; two (5%) Williams syndrome; one (2%) Kawasaki disease; one (2%) mid-aortic syndrome; one (2%) extrinsic compression to the renal artery, and eight (18%) unspecified bilateral renal artery stenosis. Hypertension was controlled with antihypertensive drugs in 17 patients. Percutaneous transluminal angioplasty (PTRA) or surgery had to be performed in 28 patients: PTRA in 16 patients, PTRA + surgery in one patient and surgery in 11 patients (four nephrectomies). The importance of vasculitic disease, especially Takayasu's arteritis, should not be underestimated in children with renovascular hypertension.

    Molecular characterization of cystinuria in south-eastern European countries

    Cystinuria is an autosomal recessive disorder caused by defective transport of cystine and dibasic amino acids in the proximal renal tubules and small intestine. So far, more than 128 mutations in SLC3A1 gene, and 93 in SLC7A9 gene have been described as a cause of cystinuria. We present a molecular characterization of the cystinuria in 47 unrelated south-east European families. The molecular methodology included direct sequencing, single strand conformational polymorphism, and restriction fragment length polymorphism. A total of 93 (94.9 %) out of 98 unrelated cystinuric chromosomes have been characterized. Mutations in SLC3A1 gene account for 64.3 % and in SLC7A9 gene for 30.6 % of the cystinuric chromosomes. Ten different mutations in SLC3A1 gene were found, and two of them were novel (C242R and L573X), while in SLC7A9 gene seven mutations were found, of which three were novel (G73R, V375I and c. 1048_1051delACTC). The most common mutations in this study were T216M (24.5 %), M467T (16.3 %) and R365L (11.2 %) in SLC3A1 and G105R (21.4 %) in SLC7A9 gene. A population specificity of cystinuria mutations was observed; T216M mutation was the only mutation present among Gypsies, G105R was the most common mutation among Albanians and Macedonians, and R365L among Serbs. The results of this study allowed introduction of rapid, simple and cost-effective genetic diagnosis of cystinuria that enables an early preventive care of affected patients and a prenatal diagnosis in affected families.

    Introduction: Ultrasound-guided prostate biopsy is the standard method for the diagnosis of prostate cancer. The aim of the present survey is to assess the variability in patient preparation and technique of ultrasound-guided prostate biopsy among Turkish Urologists. Materials and Methods: In July 2004, a questionnaire was sent out to e-mail addresses of the members of Urooncological Association, asking about the details of prostate biopsy protocol of the members. The survey consisted of multiple choice questions about the patient preparation and prostate biopsy technique. Responses were acquired via e-mail and analyzed in detail. Results: Thirty two urologists from 24 centers responded. The biopsy procedure was performed by the urologist only in 54.16% of the centers, both urologist and radiologist in 37.5%, and radiologist only in 8.33%. Transrectal route was the most common method for ultrasound-guided prostate biopsy. A half of the responders performed biopsy when PSA was greater than 4 ng/ml. All of the centers administered antibiotic and a half of them used enema before the procedure. Approximately 37% of responders did not administer any type of analgesia, but 29.1% of all responders administered a periprostatic nerve block for reducing pain during the procedure. Most urologists obtained 10 or 12 biopsy cores and only 20.8% of them obtained routine transitional zone biopsy during the initial biopsy session. Conclusion: This survey demonstrated that patient preparation and technique of ultrasound-guided prostate biopsy is not standardized among Turkish Urologists, and a guideline on prostate biopsy is needed.
