- Purpose: The aim of this study was to identify short-term complications after video-assisted gastrostomy in children and to examine the association between complications and underlying disease.Methods: This was a retrospective study at a single institution. Data for all children who underwent video-assisted gastrostomy during 12 years was collected. Complications occurring within three months postoperatively were analyzed.Results: Among 421 children undergoing video-assisted gastrostomy, 402 were included in the study. The median age at surgery was two years (range one month-14 years). The most common underlying disorder was neurological disease (49%). There were two major postoperative complications and 78% had minor complications. Minor complications included granulation tissue (43%), leakage (16%), wound infection (14%), vomiting, dislodgement and pain. There was no significant difference in frequency of the various complications when compared between the underlying diseases (p=0.10-0.82). Wound infection was registered in overall 14% and occurred least frequently in children with neurologic disease and syndromes (10% and 9% respectively).Conclusion: Serious complications after video-assisted gastrostomy are rare, while minor complications occur in 78% of the children. There is no association between the frequency of complications and underlying disease according to this study.

- BACKGROUND/AIMS: Hepatobiliary malignancies are frequently seen in primary sclerosing cholangitis (PSC) and they complicate the evaluation of patients and timing of liver transplantation. METHODS: Data from all Nordic PSC patients listed for liver transplantation during 1990-2001 were recorded prospectively. Predictors of hepatobiliary malignancy and patient survival rates have been analysed. RESULTS: Hepatobiliary malignancy was found in 52/255 (20%) patients accepted to the waiting list. Recent diagnosis of PSC, no ursodeoxycholic acid (UDCA) treatment, clinical suspicion and previous colorectal-cancer were predictors of malignancy. Among 89 patients with a strong suspicion of malignancy prior to acceptance, 35 (39%) had confirmed malignancy. A clinical suspicion had been raised in 35/52 (67%) patients with malignancy. Malignancy was found in 31/223 patients who received a liver allograft. The 1-, 3- and 5-year patient survival rates following transplantation for patients with PSC and cholangiocarcinoma were 65, 35 and 35%, respectively. CONCLUSIONS: Hepatobiliary malignancy is suspected in 1/3 of the PSC patients and found in 1/5. Although cholangiocarcinoma is regarded as a contraindication to liver transplantation (LTX), PSC patients with cholangiocarcinoma had a 35% 5-year survival following transplantation.

- 6-Hydroxy-d-nicotine oxidase (6-HDNO) of Arthrobacter oxydans, an enzyme inducible by dl-nicotine, contains FAD covalently bound via an 8α-N(3)His linkage. Expression of the gene encoding 6-HDNO and flavinylation of the protein were studied in Bacillus subtilis. In this heterologous system the following findings were made. 1. An enzymically active covalently flavinylated 6-HDNO of normal size can be expressed in B. subtilis. 2. The natural promoter of the 6-HDNO gene appeared inefficient in B. subtilis. The B. subtilis sdh promoter, when inserted upstream of the A. oxydans promoter, increased 6-HDNO expression >50-fold. 3. Expression of the 6-HDNO gene from plasmids in B. subtilis was, independently of the promoter construct used, stimulated more than fivefold by dl-nicotine in the growth medium. It is concluded that flavinylation of 6-HDNO is possibly autocatalytic and mediated by factors generally found in bacterial cells.
