Chest wall reconstruction after rib resection is essential to ensuring chest wall stability, avoiding flail chest and pulmonary hernia, and improving pulmonary function. Traditionally, a synthetic mesh and a musculocutaneous flap have been used to bridge the chest wall defect. However, a risk of secondary prosthesis infection exists. Acellular dermal collagen mesh implants (Permacol™) are indicated for the reconstruction and reformation of human soft connective tissue. A case of a complex chest wall reconstruction after rib resection for osteomyelitis due to staphylococcus aureus infection in a malnourished, immunosuppressed, and methadone-addicted patient is presented. The patient underwent a left posterolateral thoracotomy and chest wall resection, involving three ribs and the soft tissues overlying an infected cutaneous fistula. The chest wall was reconstructed using a 28 × 18 cm piece of porcine sterile acellular dermal collagen mesh. A successful chest wall repair was achieved with no incisional herniation and with complete mesh incorporation, allowing physiologic respiratory movements. A typical wound seroma developed and resorbed over the following months. There was no infection. In conclusion, this case report suggests that Permacol™surgical implant can be used successfully as an alternative to synthetic mesh in reconstruction of an infected chest wall.

Annual maximum rainfall intensity for several duration and return periods has been analyzed according to the Gumbel distribution. The Intensity-Duration-Frequency (IDF) curves before and after 1980 have been computed and compared. For the city of Toronto, it is shown that the rainfall intensities after 1980 are lower than those from before this date. This is especially clear for those of short duration. Comparing our results with those of other authors, it appears that, for the moment, no general law on the impact of global warming on the curves intensity duration frequency cannot be made. It appears that the impact of global warming on rainfall varies with geographic location and that it is not possible to draw some general conclusions across the planet.

Spring recession flows are analyzed from a Bayesian point of view. Two general equations are derived and it is shown that the classical formulas of recession flow are particular cases of both equations. It is shown that most of the recession equations reflect a non-Markovian process. That means that the groundwater storage exhibits a memory effect and that there is a nonlinear relationship between flow and storage. The Bayesian approach presented in this paper makes it possible to give a probabilistic meaning to recession flow equations derived according to a physical approach and can be an alternative to the study of complex reservoir for which the physical processes governing recession flow are unclear. Twelve spring recession flow series are analysed in order to validate the probabilistic approach presented in this paper and a conceptual model of storage-outflow is proposed.

Although the occurrence of coronary stent fracture is rare, recent reports showed that stent fracture after sirolimus-eluting stent (SES) implantation may be associated with neointimal hyperplasia and restenosis. We report two cases of stent fracture that occurred late after elective SES implantation into the right coronary artery (RCA) that were related to the aneurysm, restenosis, thrombosis, and vessel occlusion.
