Background: Open access gastroscopy allows physicians to refer patients for endoscopic procedures without a prior consultation.

Objectives: To compare the safety and efficacy of OAG[1] with gastroscopy performed after a gastroenterological consultation.

Methods: Patients referred for gastroscopy directly (open access) or after consultation with a gastroenterologist, by physicians in the departments of internal medicine and surgery at a major tertiary center, were compared for indications, background disease, outcome and diagnostic yield. The data were collected prospectively over a 5 month period following the introduction of OAG at the center. Physicians in both departments participated in an education program on the indications and procedure of gastroscopy. For each patient referred for OAG the attending physician completed a specially designed questionnaire that had to be signed by a senior physician. Data were managed and analyzed with Excel and SPSS software.

Results: The study sample comprised 494 patients: of whom 236 were referred for OAG and 258 after prior consultation. On multivariate analysis, hospitalization in the department of internal medicine was the only independent factor for OAG. Severe background disease and aspirin treatment had no effect on physician use of OAG, although they served as a “red light” for the gastroenterology consultants. There was no difference in the diagnostic yield of the procedures (26.4% normal findings for OAG and 28.3% for consultations) or in mortality rates. The main indications for referral to gastroscopy in the surgery department were melena, hematemesis, and "coffee grounds," and anemia and vomiting in the internal medicine department.
Conclusions: OAG is feasible and beneficial in an academic medical center setting, with no bias in appropriateness of indications or decrease in the diagnostic yield compared to the traditional approach. More attention should be directed to safety issues by the referring physicians

Background: Despite improved management of heart failure patients, their prognosis remains poor.

Objectives: To characterize hospitalized HF[1] patients and to identify factors that may affect their short and long-term outcome in a national prospective survey.

Methods: We recorded stages B-D according to the American College of Cardiology/American Heart Association definition of HF patients hospitalized in internal medicine and cardiology departments in all 25 public hospitals in Israel.

Results: During March-April 2003, 4102 consecutive patients were recorded. Their mean age was 73 ± 12 years and 57% were males; 75.3% were hypertensive, 50% diabetic and 59% dyslipidemic; 82% had coronary artery disease, 33% atrial fibrillation, 41% renal failure (creatinine ³ 1.5 mg/dl), and 49% anemia (hemoglobin £ 12 g/dl). Mortality rates were 4.7% in-hospital, 7.6% at 30 days, 18.7% at 6 months and 28.1% at 12 months. Multiple logistic regression analysis revealed that increased 1 year mortality rate was associated with New York Heart Association III–IV (odds ratio 2.07, 95% confidence interval 1.78–2.41), age (for 10 year increment) (OR[2] 1.41, 95% CI[3] 1.31–1.52), renal failure (1.79, 1.53–2.09), anemia (1.50, 1.29–1.75), stroke (1.50, 1.21–1.85), chronic obstructive pulmonary disease (1.25, 1.04–1.50) and atrial fibrillation (1.20, 1.02–1.40).

Conclusions: This nationwide heart failure survey indicates a high risk of long-term mortality and the urgent need for the development of more effective management strategies for patients with heart failure discharged from hospitals.

Background: Q fever is endemic in Israel, yet a large series describing the clinical spectrum of inpatients with acute Q fever in Israel is lacking. 

Objectives: To report on the clinical characteristics and outcome of hospitalized patients with acute Q fever in Israel. 

Methods: We conducted a retrospective study of 100 patients hospitalized in six medical centers, in whom acute Q fever was diagnosed by the presence of immunoglobulin G and M antibodies to phase II Coxiella burnetti antigens. 

Results: The mean age of the patients was 42.7 ± 17.3 years with a male to female ratio of 1.6:1. Acute Q fever occurred throughout the year but was more common during the warm season. The most common clinical presentation was acute febrile disease (98%, mean length of fever 15.5 ± 8.6 days), followed by hepatitis (67%) and pneumonia (32%). The prominent laboratory findings included: accelerated erythrocyte sedimentation rate, normal or low white blood count with many band forms, thrombocytopenia, and abnormal urinalysis. Although the diagnosis of acute Q fever was not known during the hospitalization in the majority of patients, about 80% of our patients received appropriate antibiotic therapy and all patients recovered. 

Conclusions: Patients with acute Q fever present with a typical clinical picture that enables clinical diagnosis and empiric therapy in most cases. The prognosis of hospitalized patients with acute Q fever is excellent.

Background: Puncture wounds in the feet of children present a clinical dilemma.

Objectives: To evaluate our approach, we reviewed the charts and all available images of 80 children admitted to our institution because of plantar punctures from 1988 to 1999.

Methods: The charts of 80 children were reviewed retrospectively.

Results: Three groups of patients were found: 59 with superficial cellulitis, 11 with retained foreign bodies, and 10 with osteomyelitis and/or septic arthritis. There was a significant presentation delay in patients from the second and third groups. Most common organisms were Staphylococcus aureus or Group A Streptococcus. Of the 80 children, 34 were treated surgically and 46 were treated with antibiotic therapy alone. All patients with osteomyelitis and septic arthritis were re-examined; at follow-up, all but one were asymptomatic apart from residual radiologic sequelae in four.

Conclusions: Patients with an established infection 24–36 hours after a plantar puncture should be admitted to hospital for parenteral antibiotic therapy. Delayed presentation is a significant marker for deep-seated infection. Further infection or relapse after initial improvement suggests the presence of osteomyelitis or a retained foreign body. A bone scan is advisable in all patients with suspected osteomyelitis: a positive bone scan necessitates aggressive early debridement combined with appropriate antibiotics; while negative bone scan, X-ray and exploration suggest that the infection is due to a foreign body, which can be detected by computed tomography.
 

Background: The evaluation of hospitalized patients with chest pain and non-diagnostic electrocardiogram is problematic and the optimal cost-effective strategy for their management controversial.

Objectives: To determine the utility of myocardial perfusion imaging with thallium-201 for predicting outcome of hospitalized patients with chest pain and a normal or non-diagnostic ECG.

Methods: On pain cessation, 109 hospitalized patients, age 61+14 years (mean+SD), with chest pain and non-diagnostic ECG underwent stress myocardial perfusion SPECT imaging with thallium-201. Costs related to their management were calculated. The occurrence of non-fatal myocardial infarction or cardiac death was recorded at 12+5 months follow-up.

Results: A normal SPECT was found in 84 patients (77%). During one year follow-up, only 1 (1.2%) compared to 7 (28%) cardiac events (6 myocardial infarctions, 1 cardiac death) occurred in patients with normal versus abnormal scans respectively (P < 0.0001). Negative predictive value and accuracy of the method were 99% and 83% respectively. Multivariate regression analysis identified an abnormal SPECT as the only independent predictor of adverse cardiac event (P = 0.0016). Total cost from admission until discharge was 11,193 vs. 31,079 shekels (P < 0.0001) for normal and abnormal scan. Considering its high negative predictive value, shortening the hospital stay from admission until scan performance to 2 days would result in considerably reduced management costs (from NIS 11,193 to 7,243) per patient.

Conclusion: Stress SPECT applied to hospitalized patients with chest pain and a normal or non-diagnostic ECG is safe, highly accurate and potentially cost effective in distinguishing between Iow and high risk patients.
