Pneumonie postopératoire : nosocomiale,iatrogène,prévisible, évitable ou non ?

We report the case of a 52-year-old man, ASA 3-4, malnourished, heavy smoker and drinker at the stage of chronic obstructive pulmonary disease and cirrhosis. The postoperative course of a cervical cancer surgery was complicated by a pneumonia with fatal outcome in the intensive care unit. Taking into account the patient's history and surgical requirements, this nosocomial infection did not appear easily preventable. The multiple risk factors and the few preventive measures usable were analyzed. In this context, the media and legal trend to make the doctors responsible for the nosocomial infections should be revised.

Arthrite septique à pyogène de l'adulte

Septic arthritis has shown no change in incidence, and despite advances in antimicrobial therapy is often responsible for residual functional impairment and for a high mortality rate among debilitated patients. Risk factors include older age, diabetes mellitus, rheumatoid arthritis, immunodeficiency, and a preexisting joint disease (e.g., rheumatoid arthritis) to which the symptoms of septic arthritis are sometimes ascribed. Staphylococcus aureus contributes over two-thirds of identified organisms; a range of streptococci and gram-negative bacilli are next in frequency. The most common site is the knee, followed by the hip and shoulder. Over 10 % of patients have polyarticular involvement reflecting bacteremia and diminished resistance to infection; (over 50% of polyarticular forms occur in rheumatoid arthritis patients). Prosthetic joint infection is becoming increasingly common; chronic forms due to intraoperative contamination and resulting in septic loosening should be distinguished from acute hematogenous infection in which emergency treatment can allow to salvage the prosthesis. Demonstration of the organism in the joint is the key to the diagnosis. Joint aspiration should be performed on an emergency basis, if needed after identification of radiographic landmarks or under ultrasonographic guidance. Seeding the fluid on blood culture flasks immediately after aspiration increases the yield. Antibiotics should be started as soon as the microbiological specimens have been collected. When aspiration is difficult (hip) or inadequate, arthroscopic drainage usually makes arthrotomy unnecessary. Early antiinflammatory therapy (nonsteroidal antiinflammatory drugs, systemic or local glucocorticoids, anticytokines, and antiinflammatory cytokines) are being considered as tools for limiting joint damage; their efficacy and safety will first have to be established in animal studies.     

Calciphylaxie non urémique iatrogène : une nouvelle observation

Calciphylaxis is a rare and severe condition, characterized by calcification and thrombosis of small vessels, mainly affecting the skin. It is most often described in patients with end-stage renal disease on dialysis. Rarer cases of non-uremic calciphylaxis are reported. The prognosis is grim and the treatment is not well codified. Sodium thiosulfate has been used for more than a decade in the treatment of uremic calciphylaxis and has been shown to be effective. Its use in non-uremic cases has been reported in a few rare observations. Rheopheresis is a technique very recently used as an adjuvant treatment in uremic calciphylaxis. We describe a case of non-uremic calciphylaxis in a patient with normal renal function and with calcium supplementation. Sodium thiosulfate was introduced, then discontinued due to the patient's poor tolerance for this treatment. Rheopheresis was then used and allowed the acceleration of healing process and a significant reduction in pain. These two treatments are promising, larger studies are needed to establish their effectiveness in non-uremic calciphylaxis.     

Risques de l'irrigation au peroxyde d'hydrogène en chirurgie de guerre

Two cases of severe complications due to injection of hydrogen peroxide under pressure into areas of muscular attrition in war wounds are reported. In both cases the administration of hydrogen peroxide was associated with tachypnoea, with major arterial desaturation and a precordial « mill-wheelmurmur was heard. In one case, these symptoms were followed by hemiplegia caused by paradoxical arterial gas embolism, and in the other case by a pulmonary oedema confirmed by computerized tomography. Both patients recovered under hyperbaric oxygen therapy. The release of gaseous oxygen under the effect of tissue catalase and the membrane peroxydasic activity of hydrogen peroxide initiate such complications. The injection of hydrogen peroxide under pressure into a closed or partially closed cavity should therefore be strictly prohibited.
