ABSTRACT
Anterior urethral valves (AUVs) is an unusual cause of congenital obstruction of the male urethra, being 15-30 times less common than posterior urethral valves. We present a case of AUV diagnosed at 24th gestational week. Ultrasonography and fetal MRI revealed hydronephrotic kidneys with ureteral duplicity, a distended bladder and perineal cystic mass which confirmed dilated anterior urethra in a male fetus. Diagnosis was confirmed postnatally by voiding cystourethrogram and surgery.
ABSTRACT
AIM: The tumor necrosis factor receptor 2 (TNFR2) is expressed in placental tissue and it is involved in immune responses, inflammation, angiogenesis and blood pressure regulation; which makes it an attractive pre-eclampsia (PE) candidate gene. Furthermore, TNFR2 expression is altered in the first trimester in placentas of women who are destined to develop PE. Therefore, we examined the association between maternal and fetal genetic variants of TNFR2 and PE. MATERIAL AND METHODS: Women with PE (n = 157) and their offspring with PE (n = 60) were compared to a control group of women (n = 97) and their offspring (n = 52) in the same Tunisian hospital-based population. We genotyped by polymerase chain reaction and restriction fragment length polymorphism the T/G polymorphism at position 676 in exon 6 (rs1061622) of the TNFR2 gene and examined its association with PE. RESULTS: The frequencies of TNFR2 (G/G) genotype and G allele were higher in the mothers with PE (n = 154) compared to the control group (15.3% vs 4.1% and 37% vs 26.3%, respectively); furthermore, the difference reached statistical significance (P = 0.002, odds ratio = 4.9; 95% confidence interval: 1.69-17.4 and P = 0.03, odds ratio = 1.69; 95% confidence interval: 1.03-2.8, respectively). In contrast, the fetal genotype and allele frequencies of this polymorphism had no effect on the risk of PE. CONCLUSIONS: The exon 6 polymorphism in TNFR2 (rs1061622) or a gene at proximity is associated specifically with PE at least in the Tunisian population and could increase the risk for PE for mothers carrying the homozygote minor allele. Nevertheless, these results need to be confirmed in other populations.

OBJECTIVE: To evaluate locoregional recurrence rate of breast cancer, determine its anatomoclinical characteristies and discuss the available therapeutic alternatives. PATIENTS AND METHODS: A retrospective study including 41 patients with LRR following modified radical mastectomy or conservative surgery of invasive breast carcinoma without metastasis, between January 1993 and December 2002. RESULTS: 38 cases of LRR occurred after mastectomy and 3 cases after conservative surgery. LRR rate was 4.84%, mean follow-up 44.7 months. Mean age of patients was 45 years and LRR mean occurrence time-interval 22.4 months. Recurrence was parietal in 25 cases, mammary in 2 cases, and nodal in 14 cases. 18 patients had to be operated on. CONCLUSION: Prognosis of breast cancer depends on distant metastasis. LRR constitutes the second major risk liable to influence the overall prognosis.
