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: Post-pericardiotomy syndrome (PPS) is a major cause of pericarditis, yet data on the risk of recurrence are limited, and the impact of steroids and colchicine in this context is unknown.

Objectives: To examine the effect of prednisone and colchicine on the rate of recurrence of PPS.

Methods: Medical files of patients diagnosed with PPS were reviewed to extract demographic, echocardiographic, X-ray imaging, and follow-up data.

Results: The study comprised 132 patients (57% men), aged 27–86 years. Medical treatment included prednisone in 80 patients, non-steroidal anti-inflammatory agents in 41 patients, colchicine monotherapy in 2 patients, and no anti-inflammatory therapy in 9 patients. Fifty-nine patients were given colchicine for prevention of recurrence. The patients were followed for 5–110 months (median 64 months). Recurrent episodes occurred in 15 patients (11.4%), 10 patients had a single episode, 4 patients had two episodes, and one patient had three episodes. The rate of recurrence was lower in patients receiving colchicine compared to patients who did not (8.5% vs. 13.7%), and in patients not receiving vs. receiving prednisone (7.7% vs. 13.8%) but the differences were non-significant. Twenty-three patients died and there were no recurrence-related deaths.

Conclusions: The rate of recurrence after PPS is low and multiple recurrences are rare. The survival of patients with recurrent PPS is excellent. Prednisone pre-treatment was associated with a numerically higher rate of recurrence and colchicine treatment with a numerically lower rate, but the differences were non-significant.

Background: Temporary abdominal closure (TAC) surgical technique relates to a procedure in which the post-surgical abdominal wall remains open in certain indications. The Bogota bag (BB) technique is a tension-free TAC method that covers the abdominal contents with a sterilized fluid bag. There are very few reports of pediatric patients treated with this technique.

Objectives: To describe our institution’s 15 years of experience using the BB technique on pediatric patients.

Methods: A retrospective cohort study describing our experience treating patients with BB was conducted. The medical files of 17 pediatric patients aged 0–18 years were reviewed.

Results: Between January 2000 and December 2014, 17 patients were treated with BB at our medical center (6 females, median age 12 years). Indications for BB were a need for a surgical site re-exploration, mechanical inability for primary abdominal closure, and high risk for ACS development. Median BB duration was 5 days and median bag replacement was 2 days. Median ICU length of stay (LOS) was 10 days and hospital LOS was 27 days. The ICU admission and BB procedure was tolerated well by 6 patients who were discharged home without complications. Of the remaining 11 patients, 6 patients died during the admission (35%) and the others presented with major complications not related to the BB but to the patient's primary disease.

Conclusions: This report represents the largest series of children treated with BB. The technique is simple to perform, inexpensive, and has very few complications.

Background: With the recent introduction of high-sensitivity troponin (hsTn), the incremental benefit of stress myocardial perfusion imaging (MPI) in the evaluation of patients who present to the emergency department (ED) with acute coronary syndrome (ACS) is unclear.

Objectives: To assess the added value of stress MPI in low-risk ACS patients with normal range hsTnI.

Methods: We analyzed all patients who were hospitalized at our medical center from February 2016 to November 2017, who presented with low-risk ACS and underwent stress MPI, and in whom hsTnI was in the normal range after the introduction of hsTnI.

Results: During the study period, 161 patients were admitted with a diagnosis of unstable angina (i.e., ACS with normal range hsTnI) and underwent stress MPI during index admission. The study population included 52/161 patients (31.7%) with low-risk ACS who had no indication for initial invasive strategy. No patients had positive MPI. One patient underwent coronary angiography due to suggestive history; however, he did not have a significant coronary artery disease and had no indication for percutaneous coronary intervention.

Conclusions: In patients with low-risk ACS and normal range hsTnI without additional high-risk features, stress MPI has little additional value for the correct diagnosis and management. Prospective studies are warranted to confirm whether resting hsTnI could serve as a powerful triage tool in chest pain patients in the ED before diagnostic testing and thus, improve patient management.

Recurrent pericarditis is a state of repetitive inflammation of the pericardium with intervals of remission. The etiology of recurrent pericarditis is still largely unknown, yet most causes are presumed to be immune mediated. Genetic factors, including human leukocyte antigen (HLA) haplotypes, can be involved in dysregulation of the immune system and as a predisposition to several autoimmune conditions, including recurrent pericarditis. Several diseases are frequently associated with such manifestations. They include systemic lupus erythematosus, familial Mediterranean fever, and tumor necrosis factor receptor-associated periodic syndrome. However, idiopathic recurrent pericarditis remains the most frequently observed clinical condition and the conundrum of this disease still needs to be solved.

Background: Malignancy is a known risk factor for venous thromboembolism; however, the association with arterial thromboembolic events remains unclear.

Objectives: To examine the association between non-ST-elevation myocardial infarction (NSTEMI) and non-significant coronary artery disease (CAD) and the presence of new or occult malignancy.

Methods: An observational cohort, single-center study was performed 2010–2015. Adult patients with NSTEMI, who underwent coronary angiography and had no significant coronary lesion, were included. Using propensity score matching, we created a 2:1 matched control group of adults with NSTEMI, and significant coronary artery disease. Risk factors for new or occult malignancy were assessed using multivariate backward stepwise logistic regression analysis. The primary outcome was new or occult malignancy, defined as any malignancy diagnosed in the 3 months prior and 6 months following the myocardial infarction (MI).

Results: During the study period, 174 patients who presented with MI with non-obstructive coronary arteries were identified. The matched control group included 348 patients. There was no significant difference in the group demographics, past medical history, or clinical presentation. The incidence of new or occult malignancy in the study group was significantly higher (7/174, 4% vs. 3/348, 0.9%, P = 0.019). NSTEMI with non-significant CAD was an independent risk factor for occult malignancy (odds ratio [OR] 4.6, 95% confidence interval [95%CI] 1.1–18.7). Other risk factors included active smoking (OR 11.2, 95%CI 2.5–49.1) and age (OR 1.1, 95%CI 1.03–1.17).

Conclusions: NSTEMI with non-significant CAD may be a presenting or early marker of malignancy and warrants further investigation.

Background: Recently, studies have found that non-alcholic fatty liver disease (NAFLD) is associated with bacterial infections. Attempts to identify risk factors for recurrent urinary tract infections (rUTIs) are still underway.

Objectives: To examine a possible association between NAFLD and rUTIs among premenopausal women.

Methods: In a case-control study, 1009 hospitalized premenopausal women with a UTI during a period of 3 years were retrospectively studied. A total of 186 subjects with rUTIs and 186 controls without a history of rUTIs were included in this study. Each participant had an abdominal ultrasonogram as part of the inclusion criteria. The two groups were compared in terms of risk factors for rUTIs, such as maternal history of rUTIs, use of contraceptives, frequency of sexual intercourse, metabolic syndrome, obesity, use of probiotics, serum levels of vitamin D, and NAFLD. An rUTI was defined as three or more episodes of UTI over a period of 1 year. NAFLD was diagnosed based on abdominal ultrasonography examination.

Results: Mean age of the 372 participants was 39.7 ± 5 years. NAFLD was diagnosed in 81/186 subjects (43.5%) with rUTIs vs. 40/186 controls (21.5%), P = 0.05. Women with rUTIs were more often obese and presented with lower serum levels of vitamin D than controls. Multivariate analysis showed that NAFLD (odds ratio = 1.6, 95% confidence interval 1.3–2.0, P = 0.04) were associated with rUTIs in premenopausal women.

Conclusions: NAFLD was associated with rUTI in premenopausal women, independent of metabolic syndrome. Further studies are needed to confirm this association.

Background: Cannabinoid hyperemesis syndrome (CHS) is under-recognized by clinicians. It is characterized by nausea, severe abdominal pain, and cyclical vomiting in the context of chronic cannabis use. Oral benzodiazepine is a proposed treatment for CHS. It decreases activation of Cannabinoid Type 1 Receptor (CB1) in the frontal cortex, has a sedative and hypnotic effect and reduces the anticipation of nausea and vomiting. These effects on the central nervous system (CNS) might explain its beneficial antiemetic effect for this syndrome.

Objectives: To increase the index of suspicion for CHS, a unique syndrome that requires a unique treatment with benzodiazepines and not antiemetics.

Methods: We describe a series of four patients with documented cannabis use, who were admitted to an internal medicine department of Meir Medical Center due to symptoms consistent with abdominal pain, nausea, and vomiting. They were initially treated with conventional antiemetics and proton pump inhibitors without response. Intensive investigations were conducted to exclude common and sometimes urgent gastrointestinal or CNS syndromes.

Results: After excluding urgent gastrointestinal and CNS origins for the vomiting, we suspected CHS. All four patients experienced similar symptoms and failure of conventional treatment with antiemetics and proton pump inhibitors. They experienced relief after administration of benzodiazepines.

Conclusions: A high index of suspicion for CHS allows for rapid, appropriate treatment with benzodiazepines, which in turn may lead to cessation of the debilitating symptoms caused by this syndrome.
