Abstract
Bacteria use bicarbonate as substrate for crucial metabolic reactions. We report the first case of bacteremia by capnophilic E. coli without the YadF gene (also known as CynT2 or Can2) that needs high concentrations of CO2 to non-enzymatically produce bicarbonate. This lack may also apply to previously reported capnophilic Enterobacteriaceae.

Abstract
We analyzed the incidence, clinicopathological features, risk factors and prognosis of patients with EBV-associated post-transplant lymphoproliferative disorder (EBV-PTLD) in 288 adults undergoing umbilical cord blood transplantation (UCBT) at a single institution. Twelve patients developed proven EBV-PTLD at a median time of 73 days (range, 36-812). Three-year cumulative incidence (CI) of EBV-PTLD was 4.3% (95% CI: 1.9-6.7). All patients presented with extranodal involvement. Most frequently affected sites were the liver, spleen, central nervous system (CNS), Waldeyer's ring and BM in 7, 6, 4, 3 and 3 patients, respectively. One patient had polymorphic and 11 had monomorphic EBV-PTLD (7 diffuse large B-cell lymphomas not otherwise specified, 4 plasmablastic lymphomas). We confirmed donor origin and EBV infection in all histological samples. EBV-PTLD was the cause of death in 11 patients at a median time of 23 days (range, 1-84). The 3-year CI of EBV-PTLD was 12.9% (95% CI: 3.2-22.5) and 2.6% (95% CI: 0.5-4.7) for patients receiving reduced-intensity conditioning (RIC) and myeloablative conditioning, respectively (P<0.0001). In conclusion, adults with EBV-PTLD after UCBT showed frequent visceral and CNS involvement. The prognosis was poor despite routine viral monitoring and early intervention. An increased risk of EBV-PTLD was noted among recipients of RIC regimens.

Abstract
Fifty-one children aged 2-14 years with recurrent tonsillopharyngitis, presenting dysphagia, fever and lymphadenitis, with more than two similar episodes in the last three years and showing a beta-hemolytic group A streptococci in the pharyngeal smear, were studied. They underwent random treatment for ten days with phenoxymethylpenicillin (40-60 mg/kg/day) (n = 28) or amoxicillin-clavulanic acid (20-40 mg/kg/day) (n = 23) taken orally three times a day. Clinical and bacteriological tests were carried out at 10 days and 2, 6 and 12 months post-treatment. The clinical and bacteriological results showed the superiority of the amoxicillin-clavulanic acid treatment both in the short term (disappearance of symptoms) and in the long term (decrease in recurrence). These results support the idea that betalactamases produced by the pharyngeal flora play an important role in the failures of penicillin.
