Background: A survey conducted among Israel Defense Force primary care physicians in 2001 revealed that they consider patients' needs more than they do organizational needs and that the education PCPs[1] currently receive is inadequate. In 2003 the medical corps initiated a multi-format continuous medical education program aimed at improving skills in primary care medicine.

Objectives: To measure and analyze the effect of the tailored-made CME[2] program on PCPs’ self-perception 3 years after its implementation and correlate it to clinical performance.

Methods: In 2006 a questionnaire was delivered to a representative sample of PCPs in the IDF[3]. The questionnaire included items on demographic and professional background, statements on self-perception issues, and ranking of roles. We compared the follow-up survey (2006) to the results of the original study (2001) and correlated the survey results with clinical performance as measured through objective indicators.

Results: In the 2006 follow-up survey PCPs scored higher on questions dealing with their perception of themselves as case managers (3.8 compared to 4.0 on the 2001 survey on a 5 point scale, P = 0.046), perceived quality of care and education (3.5 vs. 3.8, P = 0.06), and on questions dealing with organizational commitment (3.5 vs. 3.8, P=0.01). PCPs received higher scores on clinical indicators in the later study (odds ratio 2.05, P < 0.001).

Conclusions: PCPs in the IDF perceive themselves more as case managers as compared to the 2001 survey. A tailor-made CME program may have contributed to the improvement in skills and quality of care.

Background: Cancer is a leading cause of mortality worldwide. The most effective way to combat cancer is by prevention and early detection.

Objectives: To evaluate the outcome of screening an asymptomatic population for the presence of benign and neoplastic lesions.

Methods: Routine screening tests for prevention and/or early detection of 11 common cancers were conducted in 300 consecutive asymptomatic, apparently healthy adults, aged 25–77 years. Other tests were performed as indicated.

Results: Malignant and benign lesions were found in 3.3% and 5% of the screenees, respectively, compared to 1.7% in the general population. The most common lesions were in the gastrointestinal tract followed by skin, urogenital tract and breast. Advanced age and a family history of a malignancy were associated with increased risk for cancer with an odds ratio of 9 and 3.5, respectively (95% confidence interval 1.1–71 and 0.9–13, respectively). Moreover, high serum C-reactive protein levels and polymorphisms in the APC and CD24 genes indicated high cancer risk. When two of the polymorphisms existed in an individual, the risk for a malignant lesion was extremely high (23.1%; OR[1] 14, 95% CI[2] 2.5–78).

Conclusions: Screening asymptomatic subjects identifies a significant number of neoplastic lesions at an early stage. Incorporating data on genetic polymorphisms in the APC and CD24 genes can further identify individuals who are at increased risk for cancer. Cancer can be prevented and/or diagnosed at an early stage using the screening facilities of a multidisciplinary outpatient clinic.

The incidence of aortic valve stenosis is growing rapidly in the elderly. Nonetheless, many symptomatic patients are not referred for surgery usually because of high surgical risk. Unfortunately, percutaneous balloon valvuloplasty is unsatisfactory due to high recurrence rates. In 2002, Cribier and colleagues were the first to describe percutaneous aortic valve implantation, opening a new era of aortic stenosis management. In the present review we report a patient treated by this novel method, discuss and assess how it is implanated, report the findings of studies conducted to date, and suggest future directions for percutaneous treatment of aortic valve disease.
 

Background: Aural cholesteatoma is an epidermal cyst of the middle ear or mastoid that can only be eradicated by surgical resection. It is usually managed with radical or modified radical mastoidectomy. Clinical diagnosis of recurrent cholesteatoma in a closed postoperative cavity is difficult. Thus, the accepted protocol in most otologic centers for suspected recurrence consists of second-look procedures performed approximately 1 year after the initial surgery. Brain herniation into a post-mastoidectomy cavity is not rare and can be radiologically confused with cholesteatoma on the high resolution computed tomographic images of temporal bones that are carried out before second-look surgery.

Objectives: To present our experience with meningoceles that were confused with recurrent disease in patients who had undergone primary mastoidectomy for cholesteatoma and to support the use of magnetic resonance imaging as more suitable than CT in postoperative follow-up protocols for cholesteatoma.

Methods: We conducted a retrospective chart review of four patients.

Results: Axial CT sections demonstrated a soft tissue mass in the middle ear and mastoid in all four patients. Coronal reconstructions of CT scans showed a tympanic tegmen defect in two patients. CT failed to exclude cholesteatoma in any patient. Each underwent a second-look mastoidectomy and the only finding at surgery was meningocele in all four patients.

Conclusions: Echo-planar diffusion-weighted MRI can differentiate between brain tissue and cholesteatoma more accurately than CT. We recommend that otolaryngologists avoid unnecessary revision procedures by using the newest imaging modalities for more precise diagnosis of the patients who had undergone mastoidectomy for cholesteatoma in the past.
 

Background: West Nile virus, the etiologic agent of West Nile fever, is an emerging mosquito-borne disease. WNV[1] was recognized as a cause of severe human meningo-encephalitis in elderly patients during outbreaks in various parts of the world.

Objectives: To analyze WNV encephalitis therapy and its outcome after prescribing hyperimmune gammaglobulin therapy.

Methods: Eight subjects with WNV encephalitis were treated with supportive therapy and 5 days of IVIG[2] 0.4 g/kg/day containing high WNV antibodies obtained from healthy blood donors.

Results: Patients who were treated with IVIG as soon as possible exhibited an improvement in their symptoms. All subjects presented with high fever, progressive confusion and headaches, nausea and vomining. The Glasgow Coma Screen for six patients ranged between 8 and 13 and all were discharged with a score of 15. The remaining two subjects died during their hospitalization.

Conclusions: In severe WNV infection, where the disease affects the central and/or peripheral nervous system, early intervention with IVIG together with supportive treatment is recommended.
