Some neurological conditions require admission to an intensive care unit (ICU) where deep sedation and mechanical ventilation are administered to improve the patient's condition. Nevertheless, these treatments are not always helpful in disease control. At this stage, deep brain stimulation (DBS) could become a viable alternative in the treatment of critical neurological conditions with long-lasting clinical benefit. The value of deep brain stimulation has been investigated in the treatment of patients who had undergone surgical electrode implants as an emergency procedure to treat acute life-threatening conditions requiring admission to neurological ICU (NICU). A before-and-after perspective study was examined of seven patients who were treated with DBS for status dystonicus (SD) and post-stroke severe hemiballismus. Bilateral globus pallidus internus (GPi) DBS was performed in five SD patients and unilateral ventralis oralis anterior and posterior (Voa/Vop) nucleus of the thalamus DBS in two post-stroke hemiballismus patients. Bilateral GPi-DBS allowed SD resolution in a time lapse varying from 1 week to 3 months. No clear improvements compared to the baseline clinical condition were observed. Unilateral Voa/Vop-DBS intervention controlled hemiballismus after 10 h, and the patient was discharged in 2 days. The other patient was transferred from the NICU to the neurosurgery ward after 13 days. No surgical complications were observed in any of the above procedures. Neurostimulation procedures could represent a valuable choice in critical care conditions, when involuntary movements are continuous, life-threatening and refractory to intensive care procedures. DBS is feasible, safe and effective in selected cases. © 2013 Springer-Verlag Wien.

Background: Thymic epithelial tumours (thymoma and carcinoma) are exceptionally rare in children. We describe a national multicentre series with a view to illustrating their clinical behaviour and the results of treatment. Methods. From January 2000 all patients under 18 years of age diagnosed with "rare paediatric tumours" were centrally registered by the Italian centres participating in the TREP project (Tumori Rari in Et Pediatrica [Rare Tumours in Paediatric Age]). The clinical data of children with a thymic epithelial tumour registered as at December 2009 were analyzed for the purposes of the present study. Results: Our series comprised 4 patients with thymoma and 5 with carcinoma (4 males, 5 females; median age 12.4 years). The tumour masses were mainly large, exceeding 5 cm in largest diameter. Based on the Masaoka staging system, 3 patients were stage I, 1 was stage III, 1 was stage IVa and 4 were stage IVb. All 3 patients with stage I thymoma underwent complete tumour resection at diagnosis and were alive 22, 35 and 93 months after surgery. One patient with a thymoma metastasizing to the kidneys died rapidly due to respiratory failure. Thymic carcinomas were much more aggressive, infiltrating nearby organs (in 4 cases) and regional nodes (in 5), and spreading to the bone (in 3) and liver (in 1). All patients received multidrug chemotherapy (platinum derivatives + etoposide or other drugs) with evidence of tumour reduction in 3 cases. Two patients underwent partial tumour resection (after chemo-radiotherapy in one case) and 4 patients were given radiotherapy (45-54 Gy). All patients died of their disease. Conclusions: Children with thymomas completely resected at diagnosis have an excellent prognosis while thymic carcinomas behave aggressively and carry a poor prognosis despite multimodal treatment. © 2011 Carretto et al; licensee BioMed Central Ltd.

Thalassemia major and sickle cell disease are the two most widely disseminated hereditary hemoglobinopathies in the world. The outlook for affected individuals has improved in recent years due to advances in medical management in the prevention and treatment of complications. However, hematopoietic stem cell transplantation is still the only available curative option. The use of hematopoietic stem cell transplantation has been increasing, and outcomes today have substantially improved compared with the past three decades. Current experience world-wide is that more than 90% of patients now survive hematopoietic stem cell transplantation and disease-free survival is around 80%. However, only a few controlled trials have been reported, and decisions on patient selection for hematopoietic stem cell transplantation and transplant management remain principally dependent on data from retrospective analyses and on the clinical experience of the transplant centers. This consensus document from the European Blood and Marrow Transplantation Inborn Error Working Party and the Paediatric Diseases Working Party aims to report new data and provide consensus-based recommendations on indications for hematopoietic stem cell transplantation and transplant management. © 2014 by the Ferrata Storti Foundation.

Natural killer cells play an important role in the immune responses against cancer and viral infections. In addition, NK cells have been shown to exert a key role in haploidentical hematopoietic stem cell (HSC) transplantation for the therapy of high-risk leukemias. The anti-leukemia effect is mostly related to the presence of “alloreactive” NK cells, i.e., mature KIR+ NK cells that express inhibitory KIR mismatched with HLA class I (KIR-L) of the patient. In addition, an important role is played by certain activating KIR (primarily, but not only, KIR2DS1) upon interaction with their HLA class I ligand (C2 alleles). In general, the presence of activating KIR correlates with a better prognosis. Beside the infusion of “pure” CD34+ cells, a novel protocol has been recently developed in which depletion of αβ T cells and CD19+ B cells makes it possible to infuse into the patient, together with donor CD34+ HSCs, important effector cells including mature PB NK cells and γδ T cells. Recent studies revealed that cytomegalovirus (CMV) infection/reactivation may induce rapid NK cell maturation and greatly influence the NK receptor repertoire. The remarkable expansion of a subset expressing the activating receptor NKG2C, together with a more efficient virus-specific effector response after rechallenge with CMV (i.e., antigen specificity), and the longevity of the expanded population are all features consistent with an adaptive type of response and support the notion of a memory-like activity of NK cells. © Springer International Publishing Switzerland 2015.

Introduction: One significant obstacle to the success of allogeneic hematopoietic stem cell transplantation (HSCT) is represented by graft failure, defined as either lack of initial engraftment of donor cells (primary graft failure) or loss of donor cells after initial engraftment (secondary graft failure). Graft failure mediated by host immune cells attacking donor stem cells is named graft rejection. Factors associated with graft failure include HLA disparity in the donor/recipient pair, underlying disease, viral infections, type of conditioning regimen and stem cell source employed. Areas covered: In this article, the experts summarize current approaches to treat graft failure/rejection after HSCT, and they discuss new strategies of graft manipulation and immune therapy of particular interest for preventing/treating this complication. Expert opinion: A limited array of options is available to treat graft failure. The experts believe that re-transplantation from another donor or the same donor (if there is no evidence of immunologically mediated graft failure) is the treatment of choice for patients with primary graft failure or acute graft rejection. The experts think that strategies based on innovative approaches of graft manipulation, new agents or cellular therapies could render in the future graft failure a much less relevant problem for HSCT recipients. © 2014 Informa UK, Ltd.
