Hernias de la incisión de asistencia tras resección colorrectal laparoscópica. Influencia de la localización de la incisión y del uso de una malla profiláctica

Objectives

To determine the incidence of incisional hernia (IH) in the extraction incision (EI) in colorectal resection for cancer. To analyze whether the location of the incision has any relationship with the incidence of hernias and whether mesh could be useful for prevention in high-risk patients.

The role of stem cells in suppurative environments

Purpose:  To evaluate all consecutive patients treated with infliximab for hidradenitis suppurativa (HS).
Patients and methods:  Within 1 year, all consecutive patients seen in our department for HS (1) resistant to usual medical therapies (2) which could not be easily cured by surgery (3) not treated with new medication within 2 months before inclusion were treated intravenously with infliximab (5 mg/kg) without corticosteroids premedication. Four infusions were planned (week 0, week 2, week 6 and week 10) before the interruption of therapy and follow-up. Clinical activity of HS and quality of life of the patients were assessed immediately before the first, the third and the fourth infusions of infliximab.
Results:  Seven patients were included. Five completed the four infusions. Two patients received only three infusions because of severe side effects. The Sartorius score moderately improved with infliximab (mean score at week 0: 94 ± 39, at week 6: 71 ± 38 and at week 10: 83 ± 48). At week 6, patients judged the efficacy of therapy as marked ( n  = 1), moderate ( n  = 4) or null ( n  = 2). At week 10, five patients were evaluated and judged this efficacy as marked ( n  = 2), moderate ( n  = 2) or null ( n  = 1). The mean Skindex-29 score varied from 22 ± 11 (E: 25 ± 9, S: 13 ± 5, F: 28 ± 12) at week 0 to 18 ± 10 (E: 22 ± 8, S: 12 ± 8, F: 22 ± 12) at week 10.
Conclusion:  The efficacy of infliximab in severe HS is partial. More experience is needed before finding a place for infliximab in the therapeutic armamentarium for HS.     

Immunosuppression Minimization in Pediatric Transplantation

The greatest benefit of immunosuppression minimization for children may lie in improving patient morbidity, by the elimination of the inherent side effects of steroid and calcineurin inhibitors (CNI). The newer generation of powerful induction and maintenance immunosuppressants offers an option for selected immunosuppression minimization strategies, some of which have been shown to also reduce graft morbidity. Steroid minimization and avoidance in single-center uncontrolled trials have shown early promise and the availability of data from an ongoing randomized, prospective, controlled trial of steroid avoidance in children will provide necessary data to support a practice change for steroid elimination in children. Calcineurin inhibitor minimization and addition of mycophenolate mofetil (MMF) or sirolimus have shown variable improvements in renal function, though suboptimal efficacy and safety with the currently proposed regimes have limited their application. Randomized, prospective studies of steroid and calcineurin inhibitor minimization and/or avoidance are warranted to clearly confirm the short and long-term safety and efficacy of alternative immunosuppression combinations. Linked pharmacokinetic and mechanistic studies within these trials will allow for optimizing drug dosing and monitoring. This article reviews published experience to date with steroid and calcineurin minimization in pediatric renal transplantation and discusses the risks and benefits of these approaches.     

Composite prostheses for the repair of abdominal wall defects: effect of the structure of the adhesion barrier component

The component of a composite prosthesis, which makes contact with the visceral peritoneum, can be reabsorbable or non-reabsorbable, and laminar or reticular. This study was designed to determine whether the composition of this second, barrier component could improve its behavior at this interface. Abdominal wall defects in rabbits were repaired using a polypropylene prosthesis (PP), or the composites Sepramesh (PP+h) or Vicryl (PP+v). Fourteen days after surgery, the implants were evaluated by light and scanning electron microscopy, and immunohistochemistry. Prosthetic areas occupied by adhesions (PP: 71.08±5.09, PP+h: 18.55±4.96, P+v: 69.69±16.81%), neoperitoneal thickness (PP: 256.17±21.68, PP+h: 83.11±19.63, PP+v:213.72±35.90 μm) and macrophage counts (PP: 8.73±1.16, PP+h: 27.33±4.13, PP+v: 31.24±3.08%) showed significant differences (P<0.05). The tested biomaterials induced an optimal recipient tissue infiltration. Least adhesion formation was observed on the PP+h implants. This suggests that the second component, although reabsorbable, should be smooth in structure.     

High-Temperature Short-Time Heat Inactivation of HIV and Other Viruses in Human Blood Plasma

An ultra-short-time heating system was used to process blood plasma spiked with various viruses (HIV, vesicular stomatitis virus, encephalomyocarditis virus). Virus reduction and recovery of plasma proteins were measured at various temperatures from 65 to 85 degrees C. Processing at 77 degrees C and 0.006 s resulted in a high level of virus kill, including greater than or equal to 4.4 log10 HIV, while maintaining protein structure and activity essentially intact.     

Late postpartum eclampsia. Apropos of a case

We report the case of a 32-year-old multipara who presented preeclampsia on the fourth day after childbirth without receiving proper treatment that progressed to eclampsia 4 days later. Pregnancy and delivery had been uneventful. The patient presented proteinuria (30 mg/dl), serum total proteins 5.3 g/dl and serum albumin 3.3 g/dl. Blood pressure was controlled with methyldopa, 500 mg at six-hour intervals by intravenous route. The patient presented hypoxemia secondary to bilateral pleural effusion and aspirative pneumonia requiring mechanical ventilation and invasive hemodynamic monitoring. Treatment with cefotaxime, 1 g at six-hour intervals by intravenous route and clindamycin, 600 mg at six-hour intervals by intravenous route was initiated. Sedation was maintained with thiopental sodium, 3 mg/kg/hour in continuous infusion. At dismission, the patient was completely recovered from her clinical picture and needed no antihypertensive therapy. Physiopathologic features and the aforementioned complications are discussed with particular reference to differential diagnosis.     

Epidemiology of headache in Europe

The present review of epidemiologic studies on migraine and headache in Europe is part of a larger initiative by the European Brain Council to estimate the costs incurred because of brain disorders. Summarizing the data on 1-year prevalence, the proportion of adults in Europe reporting headache was 51%, migraine 14%, and 'chronic headache' (i.e. > or =15 days/month or 'daily') 4%. Generally, migraine, and to a lesser degree headache, are most prevalent during the most productive years of adulthood, from age 20 to 50 years. Several European studies document the negative influence of headache disorders on the quality of life, and health-economic studies indicate that 15% of adults were absent from work during the last year because of headache. Very few studies have been performed in Eastern Europe, and there are also surprisingly little data on tension-type headache from any country. Although the methodology and the quality of the published studies vary considerably, making direct comparisons between different countries difficult, the present review clearly demonstrates that headache disorders are extremely prevalent and have a vast impact on public health. The data collected should be used as arguments to increase resources to headache research and care for headache patients all over the continent.
