Background: Recent data regarding polymicrobial bacteremia (PMB) are lacking.

Objectives: To characterize risk factors as well as clinical, microbiological, and prognostic patterns of patients with PMB in a modern hospital setting.

Methods: A single center retrospective study including all patients diagnosed with PMB during 2013 was conducted. PMB was defined as two or more organisms cultured from the blood of the same patient within 72 hours. Patients with monomicrobial infections served as controls.

Results: There were 135 episodes (2% of all bacteremia episodes) of true PMB among 123 patients during the study period. Recent invasive procedures (odds ratio [OR] 3.59, 95% confidence interval [95%CI] 1.41–9.12, P = 0.006) and foreign bodies (OR 1.88, 95%CI 1.06–3.33, P = 0.04) were risk factors for PMB when compared with 79 patients with monomicrobial bacteremia. Central-line-associated infections were the most common infection source among patients with PMB (n=34, 28%). Enterobacteriaceae were the most commonly implicated pathogen (n=95, 77%). Non-fermenting Gram-negative bacilli were significantly more common than previously reported (n=55, 45%). Although crude 30-day mortality was higher (48% vs. 33%) in PMB patients, adjusted mortality was comparable in the two groups.

Conclusions: PMB rate in our cohort was considerably lower than in previous reports. Central-line-associated infections were more common than classic PMB sources. Mortality remained high. Strategies for early identification and better care for these patients should be pursued.

Background: Behçet's disease is a multi-systemic chronic relapsing inflammatory disease, classified among the vasculitides. The heterogeneity of clinical manifestations challenges the disease management.

Objectives: To assess efficacy and safety of adalimumab in patients with active persistent Behçet's arthritis who did not respond to disease-modifying anti-rheumatic drugs and to assess the impact of treatment on the cytokine milieu.

Methods: Our cohort comprised 10 patients with active arthritis who received adalimumab in a 24-week investigator-initiated prospective open-label study. Patients who relapsed within 12 weeks following adalimumab discontinuation could enter a 3-year extension study. The patients underwent a comprehensive assessment including questionnaires and measurement of inflammatory cytokines, adalimumab serum levels, and anti-drug antibodies.

Results: A significant improvement was observed in arthritis, disease activity visual analogue scales, Behçet's disease current activity form, and interleukin-6 (IL-6) levels, but not in health assessment questionnaire and functional assessment of chronic illness therapy fatigue scale questionnaire. Resolution of oral and urogenital ulcers was achieved in all patients. Significant reduction of pain was reported by 40% of patients. The disease relapsed in 9 of 10 patients, within 2–6 weeks following adalimumab discontinuation. Of the 7 patients who continued the study, arthritis was resolved in 5. Two patients with high neutralizing antidrug antibodies titer relapsed.

Conclusions: Adalimumab treatment achieved a significant improvement in arthritis, mucocutaneous manifestations, and IL-6 levels in all study patients but only 40% reported significant pain reduction. The arthritis relapsed in 90% of patients following adalimumab discontinuation and long-term treatment was required.

Background: Bariatric surgery has become the most common and effective therapeutic option for obesity. However, it is associated with morbidity and complications. Identification of predictors for surgical complications is an unmet need.

Objectives: To determine a simple non-invasive parameter that predicts early postoperative complications following bariatric surgery.

Methods: In this retrospective study of all patients who underwent elective bariatric surgery at Nazareth Hospital EMMS during a 4-year period (2015–2018). We collected clinical and laboratory parameters and determined predictors of complications.

Results: A total of 345 patients underwent bariatric surgery during the study period. Of the patients, 51 experienced early post-bariatric surgery complications as compared to 294 patients who had no complications. Univariate analysis revealed that neutrophil-to-lymphocyte ratio (NLR) (odds ratio [OR] 1.912, P < 0.0001) and platelet to lymphocyte ratio (OR 1.015, P < 0.0001) were associated with post-bariatric surgery complications. In a multivariate logistic regression analysis, only NLR remained a significant predictor (OR 1.751, 95% confidence interval 1.264–2.425, P = 0.0008) with a receiver operating characteristic curve for NLR of 0.8404.

Conclusions: We found that the NLR predicts post bariatric surgery early complications. Further prospective studies are needed to validate our findings.

Background: There is a lack of information regarding acute pancreatitis in Israel. However, the most prevalent worldwide etiologic causes of acute pancreatitis are biliary stones and alcohol abuse.

Objectives: To delineate the prevalence, main causes, rate of recurrence, mortality, and complications of acute pancreatitis in southern Israel.

Methods: In this retrospective study medical files of all hospitalized patients diagnosed with acute pancreatitis during a 13-year period were reviewed.

Results: The study comprised 602 patients with acute pancreatitis (120/100,000 patients or 1.2/1000 admissions). The main causes were: biliary stones (41.5%), alcohol (8.8%), and drugs (8.3%). Disothiazide was the most common drug associated with acute pancreatitis followed by sitagliptin, angiotensin converting enzyme (ACE) inhibitors, and simvastatin. Undetermined etiology made up 33.6% of the cases. Recurrence rate was 33.8% (alcohol 3.7%, hypertriglyceridemia 1.8%). This finding had no implications on mortality rate, which was stable at 4.3%. Bilateral pleural effusion, advanced computed tomography severity index (CTSI) grading, older age, and being single were found to be poor prognostic predictive factors.

Conclusions: Biliary pancreatitis is the main cause of acute pancreatitis in southern Israel, similar to the rest of the world, and constitutes a much more common etiology than alcohol. Furthermore, drug-induced pancreatitis is a common etiology, with disothiazide being the most common drug associated with pancreatitis followed by ACE-Inhibitors, sitagliptin, and simvastatin. Recurrence of pancreatitis is common in this geographic area, and older age, advanced CTSI grading, bilateral pleural effusion, and being single are all poor prognostic predictive factors.

Background: Buried bumper syndrome (BBS) mostly occurs as a late complication after percutaneous endoscopic gastrostomy (PEG) insertion; however, early BBS has been rarely reported, and the treatment of this condition is still unclear.

Objectives: To evaluate the Seldinger technique for treatment of early BBS after PEG insertion.

Methods: We report two cases of early BBS in two consecutive patients who underwent PEG insertion to maintain oral intake. The first patient was an 83-year-old woman showing Alzheimer type dementia, while the other one was a 76-year-old man who presented with maxillary cancer and treated with radiotherapy followed by left maxillectomy. Post-surgery, he developed progressive difficulty of swallowing due to mouth deformation and treatment related nerve toxicity. The first patient presented with fever and purulent discharge from the gastrostomy insertion site, without ability to rotate or slide the tube through the stoma 10 days after the PEG insertion. The man was admitted to the hospital 5 days following PEG insertion due to a fever of 38°C and peritubal swelling with purulent discharge. In addition, the tube could not rotate or slide through the stoma.

Results: Buried bumper syndrome was demonstrated by computed tomography scan. Gastroscopy and gastrostomy tube replacement was performed successfully according to the Seldinger technique (replacement over guidewire) in both cases. Correct intragastric tube positioning was demonstrated radiographically before resuming tube feeding. The two patients were discharged in good physical condition several days later.

Conclusions: External replacement over guide wire should be considered in such cases.

Background: Hepatitis C virus (HCV) is a leading cause of cirrhosis and hepatocellular carcinoma worldwide. Several viral and host factors related to viral response have been reported in the era of treatment with pegylated (PEG)-interferon and ribavirin.

Objectives: To quantify histological findings from patients with chronic HCV using computerized morphometry and to investigate whether the results can predict response to medical treatment with peg-interferon and ribavirin.

Methods: We followed 58 patients with chronic HCV infection with METAVIR score F1 and F2 in our liver unit who were grouped according to treatment response sustained viral response (SVR) and non-SVR. Liver needle biopsies from these patients were evaluated and histological variables, such as inflammatory cells, collagen fibers and liver architecture, were quantified using computerized morphometrics. The pathologist who performed the histomorphometric analysis was blinded to previous patient clinical and histological information.

Results: Histomorphometric variables including the density of collagen fibers were collected. The number of inflammatory cells in the portal space and textural variable were found to be statistically significant and could be used together in a formula to predict response to treatment, with a sensitivity of 93% and a 100% specificity.

Conclusions: Histomorphometry may help to predict a patient's response to treatment at an early stage.

Background: In an effort to alter eye color during World War II, devout Nazi researcher Karin Magnussen had adrenaline eye drops administered to inmates at the concentration camp Auschwitz-Birkenau. A Sinti family, with a high prevalence of heterochromia iridis, was forced to participate in this study. Members of this family, as well as other victims, were later killed and had their eyes enucleated and sent to Magnussen for examination. Magnussen articulated the findings of these events in a manuscript that has never been published. The author is the first ophthalmologist to review this manuscript. The generation who experienced the atrocities of World War II will soon be gone and awareness of what happened during this tragic chapter of world history is fading.

Objectives: To describe these events to raise awareness among future generations.

Methods: A literature review and archival search was conducted.

Results: Magnussen’s research was based on an animal study published in 1937. For Magnussen’s study, adrenaline drops were administered to inmates, including a 12-year-old girl from the Sinti family. As there was a reported case of deaf-mutism within the family, Waardenburg syndrome seems to be the most plausible explanation for this family’s heritable heterochromia.

Conclusions: The effort to change eye color was doomed to fail from the beginning because there was a probable diagnosis of Waardenburg syndrome. Extinction of humans for ophthalmological research is an insane act beyond imagination. For the sake of these victims, and for the generations who still feel their pain, it is imperative to tell their stories.
