We report the case of a 6-year-old boy diagnosed with acute promyelocytic leukemia (AML-M3V) when he presented with pallor, abdominal pain, anorexia, and fatigue. Induction chemotherapy was started according to the AML-BFM 98 protocol along with Vesanoid (ATRA, All-trans retinoic acid). On the sixth day of induction, he developed splenic and gallbladder infarcts. Splenectomy and cholecystectomy were performed while chemotherapy induction continued as scheduled. Four days later, he developed ischemic areas in the kidneys and ischemic colitis in the sigmoid colon. Hypercoagulation studies showed severe deficiency of protein C. Tests showed protein C 16% (reference range 70-140%), protein S 87% (reference range 70-140%), antithrombin III 122% (reference range 80-120%), prothrombin time 13.6 s (reference = 11.3), INR (international normalized ratio) 1.21, partial thromboplastin time 33 s (reference = 33), fibrinogen 214 mg/dl, D-dimer 970 μg/ml, factor II 98%, and that antinuclear antibody, antiphospholipid antibodies, mutation for factor II gene (G20210A), and mutation for Arg506 Gln of factor V were all negative (factor V Leiden). There was no evidence of clinical disseminated intravascular coagulation (DIC). He was treated with low molecular weight heparin and did well. He continues to be in complete remission 7 years later with normal protein C levels. Acquired protein C deficiency can occur in a variety of settings and has been reported in acute myelocytic leukemia. However, clinically significant thrombosis in the absence of clinical DIC, such as our case, remains extremely rare. © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Background: This study aimed to provide insight into possible antibiotic drivers of methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli resistant to third-generation cephalosporins (3GCREC) in southern and eastern Mediterranean institutions. Methods: MRSA and 3GCREC susceptibility proportions from 19 regional hospitals, previously published by the ARMed project, were correlated with antibiotic use data from the same institutions. Results: Hospitals reporting below-median MRSA proportions had significantly lower total antibiotic use. MRSA proportions increased with greater use of carbapenems (P = .04). In multivariate analysis, a positive correlation was identified with the use of carbapenems (P = .002), combination penicillins (P = .018), and aminoglycosides (P = .014). No difference was ascertained between 3GCREC proportions and total antibiotic use. In multivariate linear regression, a correlation was identified only for 3GCREC (P = .005), but a negative association was evident for beta-lactamase-resistant penicillins (P = .010) and first-generation cephalosporins (P = .012). Conclusions: The results suggest an association between resistance and antibiotic use, especially for carbapenems and third-generation cephalosporins. These data support the urgent implementation of antibiotic stewardship initiatives in hospitals in developing countries that focus on more judicious use of broad-spectrum formulations. © 2010 Association for Professionals in Infection Control and Epidemiology, Inc.
