The addition of OKT3 to the immunosuppressive regimen increases the incidence of post-transplantation lymphoproliferative disorder after cardiac transplantation, and the risk increases sharply after cumulative doses greater than 75 mg. We suggest that the risks and benefits of prophylactic OKT3 administration be reassessed in the light of these findings, particularly since the value of prophylactic immunotherapy in cardiac-transplant recipients remains to be clearly established.

Background: A needs assessment for patients with hidradenitis suppurativa (HS) will support advancements in multidisciplinary care, treatment, research, advocacy, and philanthropy.

The current mortality rates of invasive fungal infection in children with cancer are lower than previously reported in children and adults. However, the proportion of non-albicans candidemia is increasing, and non-Aspergillus molds are emerging as important pathogens, which may have important implications for prophylaxis and empiric therapy. Improved prevention, early detection, and advanced treatment strategies are needed to improve the outcome.

Exserohilum is a dematiaceous fungus that may cause a spectrum of diseases in humans, including skin and corneal infection, invasive disease, and allergic fungal sinusitis. The aim of this work is to describe two new cases of Exserohilum infection and to review the literature. The review yielded 33 cases of Exserohilum infection, of which 23 were reported since 1993. Most occurred in regions with hot climates, such as India, Israel, and the southern USA. Impaired immunity was present in the majority of patients with invasive and skin infections, whereas local trauma and atopy were the predisposing factors in those with corneal infections and allergic fungal sinusitis, respectively. Surgical debridement was the principal mode of therapy for allergic fungal sinusitis. Amphotericin B was the initial single antifungal agent used in all cases of invasive disease; the response rate was low but improved with the addition of triazole agents. Outcome appeared to be better than for other mold infections and depended mainly on the underlying diseases.

Data on the risk factors for typhlitis in children with cancer are limited. The aim of the study was to define the epidemiologic and clinical features of typhlitis and to elucidate predisposing factors for its development. The medical records of pediatric patients with cancer who were diagnosed with typhlitis from 1995 to 2005 were reviewed for clinical, laboratory, and imaging findings. The results were compared with a group of patients with cancer but without typhlitis who were hospitalized during the same period. Of the 843 cancer patients, 42 (5%) had episodes of typhlitis; 32 of them (76%) were being treated for hematologic malignancies. The incidence was highest in patients with Burkitt's lymphoma (15%) and acute myeloblastic leukemia (12%). Work-up included abdominal x-ray in all patients; abdominal ultrasonography and computed tomography were performed in 23% and 11% of patients, respectively. No cases were missed by plain x-ray when compared with computed tomography and ultrasonography. The typhlitis was treated without surgery and survival was 100%. On multivariate analysis, mucositis [odds ratio (OR) = 30.7], stem cell transplantation (OR = 58.9), and receipt of chemotherapy in the previous 2 weeks (OR = 12.9) were significantly associated with the occurrence of typhlitis. We conclude that most children with typhlitis may be treated without surgery in most cases with favorable outcome. A high index of suspicion may be warranted in patients after stem cell transplantation or chemotherapy and patients with mucositis.

DKA at diagnosis was associated with less favorable long-term glycemic control as assessed by HbA1c and the rate of DKA episodes. T1D patients presenting with DKA may therefore need stricter treatment and tight follow-up.

This report presents the first case of Factor 13 deficiency in an adult female. Her hemorrhagic manifestations were repeated and severe: umbilical vein bleeding at birth, hematomas on various sites, late bleeding after cuts and, most important, severe uterine bleedings during 12 pregnancies, which were all interrupted by spontaneous abortions. Plasma infusions, assuring a Factor 13 concentration of less than 10 per cent of its normal level, normalized the hemostatic functions of the patient’s plasma clots and rendered them insoluble in concentrated urea solutions. By regular transfusions of plasma the patient’s last pregnancy had a normal course; a cesarian section was performed without any incident, and she gave birth to a normal child.
