Background: Trauma patients diagnosed with pancreatic duct injury (PDI) have a high complication rate and prolonged hospital stay. The role of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of PDI remains unclear. During the last decade, our trauma unit incorporated ERCP into the management protocol for suspected PDI cases. 

Objectives: To determine whether ERCP is a sensitive tool to detect PDI. 

Methods: This retrospective trauma patient series study assessed the diagnostic yield of ERCP in trauma cases with suspected PDI on computed tomography (CT) or intraoperatively. Between 1 January 2004 and 31 December 2011, 13 patients admitted to our medical center underwent ERCP for suspected PDI. Patient demographics, mechanism of injury, Injury Severity Score (ISS), time from injury to ERCP, and ERCP-related complications were documented and assessed. 

Results: Of the 13 patients included in the analysis, 8 stable patients with suspected PDI on CT had no leak from the main pancreatic duct on ERCP. Two of them underwent surgery for suspected pancreatic transection. ERCP confirmed a main pancreatic duct leak in three patients. Two patients underwent ERCP for suspected PDI after “damage control” surgery. No leak from the pancreatic ducts was diagnosed. No pancreas-related complications or ERCP-related complications were observed.

Conclusions: ERCP is a sensitive and relatively safe tool for the diagnosis of PDI, and its use might prevent unnecessary surgical interventions in selected trauma cases.

 

Breast magnetic resonance imaging (MRI) has an important role in the detection and diagnosis of breast cancer. Suspicious findings on MRI are further evaluated with ultrasound. This case series illustrates the use of automated breast volumetric ultrasound (ABVS) as a tool for second-look ultrasound (SLUS) following MRI. Seven women underwent breast MRI with findings necessitating SLUS. ABVS was used for second look and all MRI lesions were detected. Four cancers, one fibroadenoma and two benign lesions, were diagnosed. This case series shows that ABVS can be used as a tool for SLUS following MRI and in some cases is superior to hand-held ultrasound.

Background: Anal cancer is a relatively uncommon disease, accounting for only 4% of cancers of the lower gastrointestinal tract. 

Objectives: To summarize the single-center experience in the treatment of anal carcinoma using various radiation techniques.

Methods: We conducted a retrospective chart review of consecutive patients who were treated for anal cancer between the years 2002 and 2011. The data extracted included demographics, type of radiation technique, treatment-associated acute toxicity, and patterns of failure and survival. For statistical analysis purposes, the patients were divided into two groups according to radiotherapy technique: 2D (group A) and 3D (group B).

Results: A total of 42 patients – 25 (59.5%) females and 17 males (40.5%) – underwent definitive chemo-radiation treatment (CRT) for anal cancer. Group A comprised 26 patients and group B 14 patients. Toxicity did not differ significantly between the groups, only in grade 1-2 skin toxicity which was more common in group B. There were significant differences in the unplanned interruptions in treatment, in both the number of patients who needed a treatment break and the number of days needed (more in group A). There were no differences in treatment response and patterns of failure between these two techniques, or in overall survival between the two groups. 

Conclusions: Our study results are consistent with reported large randomized trials, indicating that current treatments for anal carcinomas are associated with high grade acute toxicity that may result in significant treatment interruptions. The 2D technique was associated with significantly more treatment interruptions, but did not differ from 3D with regard to treatment efficacy. 

 

Background: Treatment using inhaled bronchodilators for asthma with a metered dose inhaler attached to a spacer device (MDI+S) was shown to be as efficient as nebulizers. Nevertheless, nebulizers remain the treatment of choice in most hospitals. 

Objectives: To implement a policy change to improve asthma treatment in pediatric wards and the pediatric emergency department.

Methods: The study was performed in the emergency department and pediatric wards of a university medical center. The study group comprised all children admitted with a diagnosis of asthma necessitating treatment. The medical and nursing staff of both the pediatric emergency department and the pediatric wards was trained how to use metered dose inhalers attached to spacers on a regular basis in asthmatic pediatric patients. At a preset date nebulizers were replaced by spacers and their use was monitored by the supervising physician. Salbutamol was administered by metered dose inhaler (100 μg/puff) attached to a spacer device. The number of puffs was determined by severity of disease according to GINA recommendations. After 2 years the outcome and cost analysis were examined.

Results: During 3 years since the initial policy change 92.5% patients were treated with spacers throughout their hospital stay (emergency department and pediatric ward). Costs were reduced by an estimated 63%. 

Conclusions: In view of its many advantages the replacement of nebulizers by MDI+S for the treatment of acute asthma is feasible, if performed in collaboration with the staff, hospital authority and patients.

 

Background: Admission glucose levels correlate with clinical outcome in patients with type 2 diabetes mellitus (T2DM) hospitalized in general medicine wards. 

Objective: To investigate whether in-hospital hyperglycemia alone and after adjustment for age, gender and lipidemia correlates with in- and out-of-hospital mortality.

Methods: Capillary glucose, serum lipids and diagnoses at discharge among patients with T2DM hospitalized in the general medical wards of our hospital were documented. Correlation with in- and out-of-hospital mortality was determined through uni- and multivariate analyses. 

Results: Of the 4607 patients included in the study 22% died while hospitalized. From a median of five capillary glucose tests obtained per patient, average capillary glucose level was significantly lower in those who survived than in those who died (174 ± 64 vs. 180 ± 65 mg/dl, P = 0.005). Overall, blood cholesterol was higher in those who survived than in those who died (P < 0.001). Multivariate analysis, however, including age, gender, lipidemia and glycemia, showed that only age and male gender correlated with mortality.

Conclusions: Hyperglycemia was associated with increased in- and out-of-hospital mortality on univariate analysis. However, it was not an independent risk factor when corrected for age, gender and hyperlipidemia. 

 

Background: The efficacy of video-assisted thoracoscopic surgery lobectomy in patients with previous coronary artery bypass grafting (CABG) surgery is controversial.

Objectives: To investigate whether skeletonized left internal mammary artery (LIMA) mobilization contributes to the development of severe adhesions, which will affect what type of lung surgery (open or closed procedure) will be required in the future.

Methods: Eight patients (mean age 73.9 years) with previous CABG surgery using a LIMA to left anterior descending (LAD) graft underwent left-sided lobectomy for operable non-small cell lung carcinoma. 

Results: The lobectomy by thoracotomy rate was 62.5% (5 patients), generally in patients with tumors in the left upper lobe or in patients post-neoadjuvant chemotherapy, while the video-assisted thoracic surgery lobectomy rate was 37.5% (3 patients). Mean hospital stay was 8.3 days. There was no mortality or major morbidity, apart from six minor complications in four patients (50%) (air leak, atrial fibrillation, atelectasis, pneumonia). 

Conclusions: Patients with operable non-small cell lung carcinoma following CABG surgery who need left upper lobe resection do not benefit from the video-assisted thoracoscopic surgery technique due to significant adhesions between the LIMA to LAD graft and the lung. The method of preserving a small portion of the lung on the LIMA to LAD graft may help during left upper lobe resections. Adhesions in the left pleural space after LIMA mobilization appear to generally minimally affect left lower lobe video-assisted thoracoscopic surgery.

 

Background: Cannabis has been used throughout history for different purposes but was outlawed in the United States in 1937 followed by most countries. Although recently reintroduced as a medical treatment in several countries, the use of cannabis in Israel is permitted for some medical purposes but is still controversial, eliciting heated public and professional debate. The few published studies on physicians' attitudes to medical cannabis found them to be generally unsupportive. 

Objectives: To examine, for the first time, the experience, knowledge and attitudes of Israeli physicians towards medical cannabis (MC). 

Methods: A 32 item questionnaire reflected physicians' demographics, knowledge of and experience with MC and their attitudes to this treatment. 

Results: Seventy-two physicians participated in this study. Physicians generally agreed that MC treatment could be helpful for chronic and for terminally ill patients (n=61, 79.2%). Oncologists and pain specialists did not agree unanimously that MC can undermine mental health, whereas other physicians did (P < 0.001, df = 4). Physicians who recommended MC in the past (once or more) agreed more than physicians who did not with the statement "MC treatment in Israel is accessible to patients who need it" (P < 0.05, df = 2). 

Conclusions: In contrast to other studies we found partial acceptance of MC as a therapeutic agent. Further in-depth studies are needed to address regulatory and educational needs.

 

Studies of the respiratory effects of air pollution in Israel published in peer-reviewed journals have been infrequent. Most empiric evidence relates to the association between air pollution and childhood asthma; other air pollution effects on other illnesses are less thoroughly studied. Our evaluation provides a possible explanation for the quite contradictory results demonstrated in the various studies. Actual effect estimates appear to differ considerably, ranging from no air pollution effect to a reasonably strong association detected between PM10 and asthma. We attribute these discrepancies to different research methodologies and different types of data used in various studies.

Abstract

Background: The impact of admission glycated hemoglobin (HbA1c) on hospital outcome is controversial.

Objectives: To evaluate the association between admission glucose and HbA1c levels and mortality 1 year after hospitalization in the internal medicine ward.

Methods: HbA1c level of consecutive patients was measured during the first 24 hours of admission to the internal medicine ward and divided at the cutoff point of 6.5%. Three groups of patients were prospectively identified: patients with preexisting diabetes mellitus (DM), patients with glucose > 140 mg/dl (hyperglycemia) on admission and no known diabetes (H), and patients without diabetes or hyperglycemia (NDM). The primary end-point was 1 year all-cause mortality.

Results: A total of 1024 patients were enrolled, 592 (57.8%) belonged to the DM group, 119 (11.6%) to the H group and 313 (30.6%) to the NDM group. At 1 year, death occurred in 70 (11.9%) in the DM group, 12 (10.0%) in the H group and 15 (4.8%) in the NDM group (P = 0.002). Elevated admission glucose levels did not influence outcome in any of the groups. HbA1c levels were similar for survivors and non-survivors (P = 0.60). Within-group multivariate analysis adjusted for comorbidities and age showed that in the H group HbA1C levels of 6.5% or above were associated with increased mortality risk [hazard ratio (HR) 8.25, 95% confidence interval (CI) 1.93–35.21). In the DM group, HbA1c levels below 6.5% were associated with increased mortality risk (HR = 2.05, 95%CI 1.25–3.36).

Conclusions: Glucose levels upon admission did not affect mortality. However, HbA1c levels below 6.5% had opposite effects on 1 year mortality in diabetes patients and patients with hyperglycemia.
