Clostridium septicum infection of hepatic metastases following alcohol injection: a case report
Clostridium septicum infections are generally associated with gastrointestinal or hematologic malignancies. We report the first case of hepatic metastases infection with Clostridium septicum that followed alcohol injection of liver lesion. Clinicians should consider this possibility in patients with underlying malignancy who present with hepatic abscess, as prompt surgical drainage and empiric antibiotics may be life saving

Characterization of NDM-7 Carbapenemase-Producing Escherichia coli Isolates in the Arabian Peninsula
Aim: The purpose of this study was to characterize the New Delhi metallo-beta lactamase (NDM)-7-producing Enterobacteriaceae isolated in the Arabian Peninsula. Methods: Enterobacteriaceae identified to carry blaNDM-7 in a collection of 157 NDM-producing isolates from Kuwait, Oman, Saudi Arabia, and the United Arab Emirates (UAE) were investigated for their antibiotic and disinfectant susceptibility, and resistance gene content. The virulence profile, phylogenetic and sequence types of the isolates were also determined. The plasmids carrying the blaNDM-7 were transferred, and their complete nucleotide sequence was determined. Results: Four NDM-7-producing Escherichia coli isolated in Kuwait, Oman, and the UAE, respectively, were identified. They were clonally unrelated, carried a few virulence determinants only, and belonged to clonal complexes CC10 and CC23, or ST448. They were all multi-drug resistant but remained susceptible to fosfomycin, tigecycline, and colistin. In all isolates, blaNDM-7 was located on IncX3 type plasmids of a variable size, not harboring any further resistance genes. The plasmids exhibited a high degree of similarity to each other and to pKpN01-NDM7 from Canada, with various size deletions and insertions. Conclusions: Our findings show that IncX3 type plasmids play an important role in the spread of the currently rare NDM-7 variant in the Arabian Peninsula. This association of blaNDM-7 with the IncX3-type plasmid is particularly worrisome, as this type of plasmid was proved to spread other carbapenemases in various species of Enterobacteriaceae worldwide at a high efficiency. © Copyright 2017, Mary Ann Liebert, Inc. 2017
Cryptosporidiosis of the biliary tract mimicking pancreatic cancer in an AIDS patient Criptosporidiose do trato biliar simulando câncer do pâncreas em paciente com AIDS
Diarrhea caused by Cryptosporidium sp is frequent in patients with AIDS, but involvement of other organs of the digestive tract is uncommon. We report a case of Cryptosporidium-associated obstruction of the biliary tract mimicking cancer of the head of the pancreas in a 43-year-old woman with AIDS.<br>A diarréia causada pelo Cryptosporidium sp é muito freqüente em pacientes com AIDS, mas o envolvimento de outros órgãos do aparelho digestivo é incomum. Relata-se o caso de uma mulher de 43 anos, que tinha AIDS, que apresentava obstrução das vias biliares associada ao Cryptosporidium, simulando câncer da cabeça do pâncreas
