    Compartment syndrome secondary to deep burns constitutes a surgical emergency that threatens the function and viability of the affected limb. We present the case of a 37-year-old male patient who suffered an explosion resulting in deep second-degree and third-degree burns on the right upper extremity, developing progressive edema, severe pain, paresthesia, and decreased distal perfusion, findings consistent with compartment syndrome. Intracompartmental pressure measurement confirmed the need for immediate decompression, leading to a combined fasciotomy of the anterior and posterior compartments of the forearm, preserving neurovascular structures and optimizing hand function. Postoperative management included pain control, wound care, delayed coverage of deep burns with partial-thickness skin grafts, and early physical rehabilitation. Clinical evolution was favorable, with full recovery of mobility, strength, and sensation of the limb, minimal scar contracture, and satisfactory aesthetic outcomes. This case highlights the importance of early detection of burn-related compartment syndrome, precise indication for fasciotomy, and a multidisciplinary approach in plastic and reconstructive surgery to achieve optimal functional and aesthetic outcomes.

    Natural vertical transmission of dengue viruses by<i>Aedes aegypti</i>in Bolivia
    (EDP Sciences, 2011) Gilbert Le Goff; Jane Yen Revollo; Maria Madalena Pessoa Guerra; M. Cruz; Z. Barja Simon; Yelin Roca; Jorge Vargas Flores; Jean-Pierre Hervé
    The natural transmission of dengue virus from an infected female mosquito to its progeny, namely the vertical transmission, was researched in wild caught Aedes aegypti during an important outbreak in the town of Santa Cruz de la Sierra, Bolivia. Mosquitoes were collected at the preimaginal stages (eggs, larvae and pupae) then reared up to adult stage for viral detection using molecular methods. Dengue virus serotypes 1 and 3 were found to be co-circulating with significant higher prevalence in male than in female mosquitoes. Of the 97 pools of Ae. aegypti (n = 635 male and 748 female specimens) screened, 14 pools, collected in February-May in 2007, were found positive for dengue virus infection: five DEN-1 and nine DEN-3. The average true infection rate (TIR) and minimum infection rate (MIR) were respectively 1.08% and 1.01%. These observations suggest that vertical transmission of dengue virus may be detected in vectors at the peak of an outbreak as well as several months before an epidemic occurs in human population.
