1.  Treatment of obstructive uropathy in one of three young brothers suffering from Gorlin-Cohen syndrome: a case report 
BMC Urology  2012;12:2.
Background
Frontometaphyseal dysplasia, or Gorlin-Cohen syndrome, is an X-linked disorder primarily characterized by skeletal dysplasia, such as hyperostosis of the skull and abnormalities of tubular bone modeling. Some patients develop extraskeletal manifestations, such as urinary tract anomalies.
Case presentation
A 26-year-old male patient was diagnosed with frontometaphyseal dysplasia and suffered from chronic urine retention. Although the patient was primarily diagnosed with a neurogenic bladder, our work-up revealed posterior urethral valves, bladder neck stenosis, and multiple bladder stones. The patient was treated by transurethral resection of the urethral valves and bladder neck with simultaneous open cystolithotomy to remove the bladder calculi. After removal of the catheter, the patient voided normally and had no post-void residual urine. At the 1-year follow-up, he was still voiding normally; his urodynamic investigation was also normal.
Conclusions
In the recent literature, there is scarce information on the diagnosis, treatment, and follow-up of patients with malformations of the urinary tract as a result of Gorlin-Cohen syndrome. The case presented here could guide urological approaches to patients suffering from this rare condition.

2.  Risk factors for tuberculosis in dialysis patients: a prospective multi-center clinical trial 
BMC Nephrology  2009;10:36.
Background
Profound alterations in immune responses associated with uraemia and exacerbated by dialysis increase the risk of developing active tuberculosis (TB) in chronic haemodialysis patients (HDPs). In the current study, was determined the impact of various risk factors on TB development. Our aim was to identify which HDPs need anti-TB preventive therapy.
Methods
Prospective study of 272 HDPs admitted, through a 36-month period, to our institutions. Specific Relative Risk (RR) for TB was estimated, considering age matched subjects from the general population as reference group. Entering the study all patients were tested with tuberculin (TST). Using Cox's proportional hazard model the independent effect of various risk factors associated with TB development was estimated.
Results
History of TB, dialysis efficiency, use of Vitamin D supplements, serum albumin and zinc levels were not proved to influence significantly the risk for TB, in contrast to: advanced age (>65 years), BMI, diabetes mellitus, tuberculin reactivity, healed TB lesions on chest X-ray and time on dialysis. Elderly (>70 years old) HDPs (Adjusted RR 25.3, 95%CI 20.4-28.4, P < 0.02), diabetics (Adj.RR 25.3, 95%CI 17.2-21.1, P < 0.03), underweighted (Adj.RR 72.3, 95%CI 65.2-79.8 P < 0.001), tuberculin responders (Adj.RR 41.4, 95%CI 37.9-44.8, P < 0.03), HDPs with fibrotic lesions on chest x-ray (Adj.RR 82.3, 95%CI 51.3-95.5, P < 0.03) and those treated with haemodialysis for < 12 months (Adj.RR 110.0, 95%CI 97.4-135.3, P < 0.001), presented significantly higher specific RR for TB even after adjusting for the effect of the remaining studied risk factors.
Conclusion
The above mentioned factors have to be considered by the clinicians, evaluating for TB in HDPs. Positive TST, the existence of predisposing risk factors and/or old TB lesions on chest X-ray, will guide the diagnosis of latent TB infection and the selection of those HDPs who need preventive chemoprophylaxis.

3.  Sciatica due to extrapelvic heterotopic ossification: A case report 
Introduction
Sciatica is a common problem, usually caused by disc herniation or spinal stenosis. Low back pain is also present in most cases. When sciatica is the unique clinical finding, especially in young patients, extraspinal pathology should be investigated.
Case presentation
We describe a rare case of sciatica in a 32-year-old man, which was developed as a complication of post-traumatic pelvic heterotopic ossification. During the operation, the sciatic nerve was found to be bluish, distorted and compressed in an hourglass fashion around a heterotopic bone mass. The heterotopic bone tissue, 4 cm in diameter, was removed and the patient had fully recovered 3 months after the operation.
Conclusion
In cases of sciatica without back pain, the possibility of direct pressure of the sciatic nerve from cysts, tumours or bone, as in the present case, should be considered.
