Resolution of disseminated fusariosis in a child with acute leukemia treated with combined antifungal therapy: a case report
<p>Abstract</p> <p>Background</p> <p><it>Fusarium </it>spp. is being isolated with increasing frequency as a pathogen in oncohematologic patients. Caspofungin and amphotericin B have been reported to have synergistic activity against <it>Fusarium </it>spp.</p> <p>Case presentation</p> <p>We herein report a case of disseminated fusariosis diagnosed by chest CT scan and positive blood cultures to <it>Fusarium </it>spp. Because the patient's clinical condition deteriorated, CRP levels increased, and blood cultures continued to yield <it>Fusarium </it>spp. despite liposomal amphotericin B monotherapy up to 5 mg/kg daily, treatment with caspofungin was added. Within 2 weeks of onset of combined antifungal therapy, the chest CT scan demonstrated a progressive resolution of the pulmonary lesions. Upon discontinuation of intravenous antifungals, the patient received suppressive therapy with oral voriconazole. Three months later, a chest CT scan showed no abnormalities. Twenty-five months after discontinuation of all antifungal therapy, the patient remains in complete remission of her neoplastic disease with no signs of clinical activity of the <it>Fusarium </it>infection.</p> <p>Conclusion</p> <p>This is the first description of successful treatment of disseminated fusariosis in a pediatric patient with acute lymphoblastic leukemia with caspofungin and amphotericin B followed by oral suppressive therapy with voriconazole.</p
A well‐tolerated core needle muscle biopsy process suitable for children and adults
Serial muscle biopsies within clinical trials for Duchenne muscular dystrophy (DMD) are critical to document therapeutic responses. Less invasive means of sampling muscle are needed. We analyzed a retrospective consecutive case-series cohort of vacuum-assisted core needle muscle biopsy procedures performed on healthy and dystrophic individuals at a single institution assessing for safety and reliability of obtaining sufficient high-quality biopsy tissue for histologic assessment in adult and pediatric subjects. Of 471 muscle cores from 128 biopsy procedures, 377-550 mg of total muscle tissue was obtained per procedure with mean core weight of 129 mg (SD, 25.1 mg). All biopsies were adequate for histological assessment. There were no significant adverse events. This core needle biopsy approach, when combined with improved sample processing, provides a safe means to consistently obtain muscle samples for diagnostic and clinical trial applications
First case of stenting of a vulnerable plaque in the SECRITT I trial—the dawn of a new era?
Background. a 63-year-old man presented with class II anginal symptoms. Investigations. cardiac catheterization, intravascular ultrasound (IVus) virtual histology, optical coherence tomography and off-line palpography. Diagnosis. the patient was diagnosed as having a culprit lesion in the left circumflex artery and a vulnerable plaque in the left anterior descending artery. Management. the culprit lesion was treated with two overlapping drug-eluting stents. the vulnerable plaque was then treated with a self-expanding stent tailored to shield vulnerable plaques (vProtect (R) Luminal shield). after dilatation of the stent with a low-pressure balloon, IVus and optical coherence tomography showed excellent apposition of the stent to the vessel wall, with no signs of tissue prolapse or edge dissections. at the 6-month follow-up appointment, the stent showed complete tissue coverage without signs of in-stent restenosis. Conclusions. six months of follow-up has demonstrated that a patient with an IVUS-derived, thin capped fibroatheroma was successfully treated with a stent tailored to shield vulnerable plaques

Differential interactions of the formins INF2, mDia1, and mDia2 with microtubules
Three mammalian formins, although binding microtubules with high affinity, differ dramatically in their microtubule-binding mechanisms. In addition, the ability of one formin (mDia2) to bind actin is strongly inhibited by microtubules, whereas the ability of another formin (INF2) to bind microtubules is strongly inhibited by actin monomers
