Invasive pulmonary aspergillosis (IPA) is the most common fungal pulmonary infection in severely immunocompromised patients. Aspergillus species are commonly isolated from the soil, plant debris, and the indoor environment, including the hospital. Phagocytosis is the main host defense against Aspergillus conidia and hyphae. ⋯ The improved survival observed with voriconazole makes it a new reference for the first-line therapy of IA. Lipid formulations of amphotericin B, caspofungin, micafungin, and posaconazole are other therapeutic options in the event of failure of or contraindication to voriconazole. The main indication for surgery is prevention of severe hemoptysis when the lesion is adjacent to a large vessel.

Epidural spinal cord stimulation in chronic non-reconstructible limb ischemia.
For patients with chronic non-reconstructible limb ischemia (chronic CLI), spinal-cord stimulation (SCS) has been advocated for the treatment of ischemic pain and prevention of amputation. The present clinical report was performed to evaluate the long-term effects of SCS on limb survival. A retrospective review was performed of 21 patients who had undergone SCS between December 1997 and July 2002 due to chronic CLI. ⋯ Major amputation could be avoided in 15 (71%) of 21 patients. Two electrode dislocation, one pulse-generator dislocation, and one wire disconnection occurred; no other complications were observed. SCS represents a safe and effective therapy for patients with chronic non-reconstructible critical limb ischemia.

Familiarity with the appearance and habitat of venomous sea creatures, the location of their stinging apparatus, and surveillance of population concentrations within recreational waters are essential in avoiding envenomations. Compared with the thermo-stable low molecular weighted ingestible seafood toxins, venomous toxins are often large molecular weight proteins and many are heat labile, which provides opportunity for therapeutic intervention. Heat therapy may denature the toxins, and provide immediate relief of pain in coelenterate and venomous fish envenomations. ⋯ Supportive treatment includes attention to cardiopulmonary resuscitation and intubation. Exposure to Pfeisteria may result in cognitive and behavioral abnormalities. Treatment with cholestyramine may be helpful in binding the toxin and improve recovery.

Materializing research promises: opportunities, priorities and conflicts in translational medicine.
There is considerable evidence that the translation rate of major basic science promises to clinical applications has been inefficient and disappointing. The deficiencies of translational science have often been proposed as an explanation for this failure. An alternative explanation is that until recently basic science advances have made oversimplified assumptions that have not matched the true etiological complexity of most common diseases; while clinical science has suffered from poor research practices, overt biases and conflicts of interest. ⋯ Moreover, while the role of the industry is catalytic in translating research advances to licensed interventions, academic independence needs to be sustained and strengthened at a global level. Conflicts of interest may stifle translational research efforts internationally. The profit motive is unlikely to be sufficient alone to advance biomedical research towards genuine progress.
