RESUMEN
Pancreatoduodenectomy (PD) is a very complex and highly challenging operation for surgeons worldwide. It is the surgical procedure of choice for the management of benign and malignant diseases of the periampullary region. Although mortality rate following this complicated surgery has fallen to 1-3%, morbidity rate following PD remains high, with almost 30-40% of patients developing at least one complication. Postoperative pancreatic fistula (POPF) is one of the most common complications following PD. Therefore, Pancreatico-enteric anastomosis has been regarded as the "Achilles heel" of the modern, one-stage PD procedure. According to the International Study Group of Pancreatic Surgery (ISGPS), three types of POPF are recognized nowadays: biochemical leak, previously known as grade A POPF, grade B and grade C, with the latter being the most dangerous. Most POPFs, especially of the biochemical leak and grade B heal with non-operative management to recur later and present as an intra-abdominal abscess or pseudocyst, necessitating management by means of interventional radiology, endoscopy or surgery. These types of fistulas are undefined and occasionally intractable. Herein, we present two patients who presented with the aforementioned type of pancreatic fistula following duct occlusion PD. The first patient, a 53-year-old female patient, suffered from intolerance to oral feeding, severe weight loss and recurrent hospital admission, while the second patient, a 72-year-old patient, suffered from recurrent bouts of abdominal sepsis. Their management involved step-up approach, starting with non-operative management, followed by percutaneous drainage and operative treatment in the form of Puestow-like procedure (longitudinal pancreatojejunostomy), as a recourse due to the inadequacy of preceding therapeutic modalities.
RESUMEN
We evaluated Q fever prevalence in blood donors and assessed the epidemiologic features of the disease in Israel in 2021. We tested serum samples for Coxeilla burnetii phase I and II IgG using immunofluorescent assay, defining a result of >200 as seropositive. We compared geographic and demographic data. We included 1,473 participants; 188 (12.7%) were seropositive. The calculated sex- and age-adjusted national seroprevalence was 13.9% (95% CI 12.2%-15.7%). Male sex and age were independently associated with seropositivity (odds ratio [OR] 1.6, 95% CI 1.1-2.2; p = 0.005 for male sex; OR 1.2, 95% CI 1.01-1.03; p<0.001 for age). Residence in the coastal plain was independently associated with seropositivity for Q fever (OR 1.6, 95% CI 1.2-2.3; p<0.001); residence in rural and farming regions was not. Q fever is highly prevalent in Israel. The unexpected spatial distribution in the nonrural coastal plain suggests an unrecognized mode of transmission.

Emphysematous pancreatitis (EP), a severe form of necrotizing infection of the pancreas, is an extremely rare medical emergency with high rates of mortality. It is characterized by intraparenchymal pancreatic or peri-pancreatic air due to either monomicrobial or polymicrobial infection with gas-forming bacteria or due to entero-pancreatic fistula. EP is classified according to timing from disease onset when air bubble signs were detected on computed tomography (CT) scan, as early onset (within 2 weeks from disease onset) or late (more than 2 weeks from disease onset). While most cases of acute pancreatitis are resolved with supportive care alone, clinical outcomes of EP, especially the early onset subtype, are very poor with high rates of morbidity and mortality. These two case reports present the clinical features, diagnostic investigations, and management of two patients admitted to our hospital with early onset fulminant EP, each investigated and managed with different approaches. The first patient underwent a more conservative treatment, with diagnosis being made 52 h following admission, and thus, intensive care unit (ICU) admission and surgery were postponed, while the second patient was diagnosed a few hours following presentation with earlier ICU admission. In this article, we will present the critical importance of early diagnosis of the aforementioned rare entity of severe pancreatitis and will consider the consequences of rapid diagnosis on disease course, morbidity and mortality.
RESUMEN
BACKGROUND: NDM-producing Acinetobacter baumannii (NDMAb) were reported sporadically worldwide but little is known about the transmission, epidemiology and clinical features of NDMAb-infected patients. The goals of this study were to characterize (1) the epidemiology and clinical features of NDMAb-infected patients; (2) the microbiological and molecular features of NDMAb isolates and (3) the transmission networks of NDMAb within healthcare facilities. METHODS: The study was conducted at the Tel-Aviv Sourasky, Rambam and Sha'are-Zedek Medical centers (TASMC, RMC and SZMC, respectively) in Israel. All cases detected between January 2018 and July 2019 were included. Phylogenetic analysis was based on core genome SNP distances. Clonal transmission was defined according to molecular (≤ 5 SNP) and epidemiological criteria (overlapping hospital stay). NDMAb cases were compared at a ratio of 1:2 with non-NDM carbapenem-resistant A. baumannii (CRAb) cases. RESULTS: The study included 54 NDMAb-positive out of 857 CRAb patients, including 6/179 (3.3%) in TASMC, 18/441 (4.0%) in SZMC and 30/237 (12.6%) in RMC. Patients infected by NDMAb had similar clinical features and risk factors as patients with non-NDM CRAb. The length-of-stay was higher in NDMAb cases (48.5 days vs. 36 days, respectively, p = 0.097) and the in-hospital mortality was similarly high in both groups. Most isolates (41/54, 76%) were first detected from surveillance culture. The majority of isolates harbored the blaNDM-2 gene allele (n = 33), followed by the blaNDM-1 (n = 20) allele and the blaNDM-4 allele (n = 1). The majority of isolates were related within the ST level to other isolates in SZMC and RMC: 17/18 and 27/30 isolates, respectfully. The common ST's were the blaNDM-1 harboring ST-2 (n = 3) and ST-107 (n = 8) in SZMC and the blaNDM-2 harboring ST-103 in SZMC (n = 6) and in RMC (n = 27). All blaNDM alleles were located within a conserved mobile genetic environment flanked by the ISAb125 and IS91 family transposon. Clonal transmission was identified in most hospital-acquired cases in RMC and SZMC. CONCLUSION: NDMAb constitutes a minor part of CRAb cases and are clinically similar to non-NDM CRAb. Transmission of NDMAb occurs mostly by clonal spread.
