1.  Penile Prosthesis: What Should We Do about Complications? 
Advances in Urology  2008;2008:573560.
Even in the era of phoshodiesterase type 5 inhibitors, penile implants are considered the definitive solution for the treatment of organic erectile disfunction. The advent of new surgical tools and new infection-resistant materials has significantly reduced the risk of intra and post-operative complications and the need for revision surgery. Various companies have also improved their mechanical systems in order to reduce the risk of failures, and their products are now so good they may last lifelong. In this article, we evaluate the intraoperative and postoperative complications recorded in our experience and in literature reports, and make some suggestions as to how to prevent or correct them.

2.  Serum amyloid A protein concentration in bone marrow transplantation for beta thalassaemia. 
Journal of Clinical Pathology  1992;45(4):348-351.
AIMS: To investigate whether serum amyloid A protein (SAA) and C-reactive protein (CRP) concentrations could be used in the management of beta thalassaemic patients undergoing bone marrow transplantation (BMT). METHODS: Serum SAA and CRP concentrations were determined in paired samples from 66 patients with beta thalassaemia before and after BMT. Serum SAA concentrations were determined by an enzyme linked immunoassay (EIA); serum CRP concentrations were determined by a nephelometric assay. RESULTS: Serum SAA concentrations before transplantation were significantly higher in the group that subsequently rejected the transplant than the group without complications. SAA concentrations increased after BMT in acute graft versus host disease (GvHD) and rejection. No significant increase in SAA or CRP was found in chronic GvHD. Increases in serum in SAA and CRP concentrations were not related to concomitant infection episodes. CONCLUSIONS: The different acute phase response in acute GvHD and rejection compared with chronic GvHD suggests that different immunopathogenic mechanisms are responsible.

3.  Increased serum concentrations of tumour necrosis factor in beta thalassaemia: effect of bone marrow transplantation. 
Journal of Clinical Pathology  1992;45(1):61-65.
AIMS: Serum concentrations of tumour necrosis factor-alpha (TNF) were determined in beta thalassemic patients before and after bone marrow transplantation (BMT) to evaluate whether changes in TNF concentrations after BMT were related to immune mediated complications. METHODS: Serum TNF concentrations were determined by enzyme linked immunoassay (EIA) in paired samples from 71 patients with beta thalassemia before and after BMT. Serial samples from 13 patients were also studied for up to six months after BMT. Forty one normal healthy children matched for sex and age were studied as controls. RESULTS: beta thalassemic patients had high serum TNF concentrations before transplantation compared with controls. These were not related to sex, age, duration of disease, number of blood transfusions, transferrin concentrations or splenectomy. DQw1 positive patients showed significantly lower TNF concentrations than non-DQw1 cases. Patients with severe liver fibrosis had significantly higher TNF concentrations. No correlation was found between TNF values and BMT outcome before transplantation but TNF alpha values fell significantly after BMT. The decrease persisted only in patients with successful engraftment. In serial samples studied for up to six months after BMT, TNF values decreased but in four out of five patients with graft rejection and in all five with acute graft versus host disease (GVHD) sharp increases occurred at the time of clinical symptoms. No correlation was found between the degree of GVHD and serum TNF-alpha concentrations nor between TNF-alpha concentrations after BMT and the presence of bacterial, viral, and fungal infections. CONCLUSIONS: About 50% of beta thalassemic patients have increased serum TNF, and the changes after BMT are related to the occurrence of immune mediate complications. The persistence of low TNF concentrations after successful engraftment may be due to the preparative regimen and the lack of adverse immune reactions.

4.  Gonadal function after allogenic bone marrow transplantation for thalassaemia. 
Archives of Disease in Childhood  1991;66(4):517-520.
Thirty prepubertal patients with thalassaemia major (15 boys and 15 girls) aged from 9.3 to 17.2 years (mean 12.9) who had successfully undergone allogenic bone marrow transplantation were studied. Before the transplant all patients were given short courses of high doses of busulphan (total dose 14 mg/kg) followed by cyclophosphamide (total dose 200 mg/kg). Pituitary gonadal function was assessed between 0.7 and 5.1 years (mean 2.3) after bone marrow transplantation. Increased gonadotrophin concentrations indicating gonadal damage were found in 80% of the girls, probably as a result of the chemotherapy. In all the prepubertal boys the basal follicle stimulating hormone and luteinising hormone concentrations were normal. Most of the boys had reduced gonadotrophin and testosterone responses after gonadotrophin releasing hormone and human chorionic gonadotrophin tests. This could have been the result of iron overload but the effect of cytotoxic agents cannot be excluded. These findings emphasise the need for vigilant long term follow up of thalassaemic patients treated with cytotoxic chemotherapy for bone marrow transplantation so that those requiring hormone replacement can be identified and treated.
