OBJECTIVE: To investigate if the body mass index (BMI) differs between different groups of patients (incomplete ligation also defined as technical error, neo-revascularisation, uncertain and mixed) in recurrent same site inguinal varices after surgery (REVAS). METHODS: During a six and half year time span, we retrospectively analysed 203 consecutive procedures in 153 patients undergoing recurrent same site vein surgery in the groin. Individual BMI was calculated and compared within the different REVAS nature of the source groups. RESULTS: The median BMI was 28 for patients undergoing recurrent vein surgery in the groin with no relevant difference in BMI between the different source groups (confidence interval for the difference of adjusted group means equals [-1.5, 2.6]). CONCLUSIONS: There is no relevant difference in BMI between the two commonest REVAS groups. This may be due to small sample size, but confidence limits for difference of.

High-tech medicine in a low income country remains a controversial issue. In September 1997, a congenital heart surgery program was initiated in Guatemala by Aldo Castañeda, emeritus Harvard Professor of Surgery and surgeon-in-chief at the Children's Hospital Boston. He trained 3 young pediatric cardiac surgeons and in addition assembled a team of pediatric cardiologists, intensivists, anesthesiologists, nurses and the necessary technical staff to develop a pediatric cardiac program in Guatemala. Faced with limited governmental financial support, he set up the Aldo Castañeda Foundation to ensure sustainability of the program. Now, 10 years after the initiation of this program, the pediatric cardiovascular unit (UNICARP) offers diagnosis as well as medical and surgical therapy to children born with a congenital heart malformation in Guatemala and neighboring countries. In addition, UNICARP offers training opportunities for young surgeons from abroad. The experience of one such trainee from Switzerland is highlighted in this report.

A variety of randomized, controlled trials comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) found similar results in mortality but significant differences in number of reinterventions in favor of CABG. This work gives an overview about the relevance and limitations of these studies in line with newly published large scale observational studies, which reveal significantly lower mortality-rates in CABG patients. Emphasis is placed on the special situation in the diabetic patient.
