The use of TachoSil following pulmonary resection resulted in a reduction in air leakage compared with standard techniques. This reduction in air leakage resulted in a significant reduction in both the time to chest drain removal and the period of hospitalisation.

After resective and reconstructive surgery in the gastrointestinal tract, oral feeding is traditionally avoided in order to minimize strain to the anastomoses and to reduce the inherent risks of the postoperatively impaired gastrointestinal motility. However, studies have given evidence that the small bowel recovers its ability to absorb nutrients almost immediately following surgery, even in the absence of peristalsis, and that early enteral feeding would preserve both the integrity of gut mucosa and its immunological function. The aim of this study was to investigate the impact of early enteral feeding on the postoperative course following oesophagectomy or oesophagogastrectomy, and reconstruction. Between May 1999 and November 2002, forty-four consecutive patients (thirty-eight males and six females; mean age 62, range 30–82) with oesophageal carcinoma (stages I–III), who had undergone radical resection and reconstruction, entered this study (early enteral feeding group; EEF). A historical group of forty-four patients (thirty-seven males and seven females; mean age 64, range 41–79; stages I–III) resected between January 1997 and March 1999 served as control (parenteral feeding group; PF). The duration of both postoperative stay in the Intensive Care Unit (ICU) and the total hospital stay, perioperative complications and the overall mortality were compared. Early enteral feeding was administered over the jejunal line of a Dobhoff tube. It started 6 h postoperatively at a rate of 10 ml/h for 6 h with stepwise increase until total enteral nutrition was achieved on day 6. In the controls oral enteral feeding was begun on day 7. If compared to the PF group, EEF patients recovered faster considering the duration of both stay in the ICU and in the hospital. There was a significant difference in the interval until the first bowel movements. No difference in overall 30 d mortality was identified. A poor nutritional status was a significant prognostic factor for an increased mortality. Early enteral feeding significantly reduces the duration of ICU treatment and total hospital stay in patients who undergo oesophagectomy or oesophagogastrectomy for oesophageal carcinoma. The mortality rate is not affected.

In resectable N0 patients with NSCLC the microscopic invasion of blood vessels should be considered as an additional prognostic parameter.

Hydroxymethylfurfural (HMF), a well-known heterocyclic Maillard reaction product, has often been studied for its potential toxic, mutagenic, and carcinogenic effects. Recent clinical studies, however, have strongly suggested that HMF might have exciting antitumor potential. We report on the development and validation of a bioanalytical assay for HMF that could be suitable as a basis for pharmacokinetic models in cancer patients. Two strategies were tested, i.e., direct and indirect methodologies. A direct isocratic LC determination at 283 nm was designed. Two indirect attempts involved derivatization coupled to HPLC-UV. It was possible to resolve the stereoisomers of the HMF derivative, and factors influencing their equilibrium ratio are discussed. HMF was extracted from the biomatrix by solid-phase extraction using different cartridges. A comparative study was made of the implemented methods as well as the extraction protocols. Both indirect assays proved to be more sensitive and were used to assess HMF quantitatively in human plasma. However, the newly introduced derivatization conditions led to the highest sensitivity with a LOD (S/N ratio = 3) of at least 2 pmol analyte on column. The assay selectivity was satisfactory in pre- and post-dose real samples. The mean recoveries of the assays were 79% and 89%, with acceptable accuracies and reproducibilities.

We conclude that fosfomycin achieves antimicrobially effective concentrations in infected lung tissue.

An approach considering etiology and extent of perforation, diagnostic delay, and septic status is required to improve patient's outcome. Primary repair is feasible in patients without intrinsic esophageal disease and evidence of sepsis. The greater the diagnostic delay, the more the destruction of the esophageal wall especially in the case of septic esophageal disease, thus the stronger the argument for esophagectomy if anatomically and/or oncologically possible.

Until recently, information on antibiotic pharmacokinetic properties in infected human lung tissue was limited. We therefore studied a microdialysis-based approach for measurement of the penetration of meropenem into the extracellular space fluid of human pneumonic lung parenchyma. The lung penetration of meropenem was determined for seven patients with pneumonia and metapneumonic pleural empyema treated by decortication. Intraoperatively, two microdialysis probes were inserted into pneumonic lung tissue and one was inserted into healthy skeletal muscle for reference values.

Despite the limitations of a non-randomized study, photosensitzation with Photosan seems to be more effective in PDT of advanced esophageal carcinoma compared to ALA.
