Objectives: To describe and analyze how PCPs[1] in the IDF[2] view their roles as primary care providers and to characterize how they perceive the quality of the medical care that they provide.

Methods: We conducted a survey using a questionnaire that was mailed or faxed to a representative sample of PCPs. The questionnaire included demographic background, professional background, statements on self-perception issues, and ranking of roles as a PCP in the IDF.

Results: Statements concerning commitment to the patient were ranked higher than statements concerning commitment to the military organization. Most physicians perceive the quality of the medical care service that they provide as high; they also stated that they do not receive adequate continuous medical education.

Conclusions: Our survey shows that PCPs in the IDF, like civilian family physicians, perceive their primary obligation as serving the needs of their patients but are yet to take on the full role of “gatekeepers” in the IDF’s healthcare system. We conclude that the Medical Corps should implement appropriate steps to ensure that PCPs are prepared to take on a more prominent role as “gatekeepers” and providers of high quality primary medical care.

Background: During ingestible capsule endoscopy, video images are recorded throughout the device's natural propulsion through the digestive system. Shortening the transit time of the wireless video capsule through the stomach and small bowel could reduce the time needed to read and analyze the resultant images, utilize more effectively the short life of the capsule battery (7 ± 1 hours) and make it possible to image the entire small bowel.

Objective: To measure gastric and small bowel transit times, with and without preparation, using capsule endoscopy.

Methods: Capsule transit times through the stomach, small bowel and colon were evaluated by analysis of the videos generated during the capsule's passage. The study group included 62 patients with small and large bowel pathologies (e.g., iron deficiency anemia, Crohn's disease). The patients were divided into three groups: prepared with polyethylene glycol (Group A, n = 9), prepared with sodium phosphate (Group B, n = 13), and with no preparation (Group C, n = 40).

Results: The gastric emptying times were 20.4 ± 15.2 minutes in group A, 55.7 ± 45.1 in group B, and 48.3 ± 28.7 in group C (P = 0.01). The capsule produced views of the cecum in only 49 of the 62 patients. The mean small bowel transit time for these 49 patients was 238.8 ± 82.1 minutes, making the mean times for the groups (A,B,C) 148.9 ± 32.6, 289.4 ± 77.2 and 249.3 ± 73.9 minutes respectively (P = 0.0001).

Conclusion: Compared to both SP[1] and no preparation, preparation of the colon with PEG[2] significantly shortened the transit time of the capsule through the stomach and small bowel.

Background: Screening for celiac disease is based on the sequential evaluation of serologic tests and intestinal biopsy; an optimal screening protocol is still under investigation. The screening policy of one of the main healthcare providers in Israel (Maccabi) consists of measuring total immunoglobulin A and tissue transglutaminase IgA[1] antibodies and confirming positive results by endomysial antibodies. For IgA-deficient patients antigliadin IgG is measured.

Objectives: To evaluate the use of tTGA[2] as a first-level screening test in patients suspected of having celiac disease

Methods: The results of tTGA and EMA[3] tests over a 3 month period were obtained from the laboratory computer. Letters were sent to the referring physicians of patients with positive tests, requesting clinical information and small intestinal biopsy results. tTGA was performed using an anti-guinea pig tTG-IgA enzyme-linked immunosorbent assay kit.

Results: Overall, 2,505 tTGA tests were performed: 216 (8.6%) were tTGA-positive of which 162 (75%) were EMA-negative (group 1) and 54 (25%) EMA-positive (group 2). Clinical information was obtained for 91 patients in group 1 and 32 in group 2. Small intestinal biopsy was performed in 33 (36%) and 27 patients (84%) in groups 1 and 2, respectively. Celiac disease was diagnosed in 4 biopsies (12%) in group 1 and 23 (85%) in group 2 (P < 0.0001). The positive predictive value was 45% for tTGA and 85% for EMA.

Conclusions: Symptomatic patients with positive tTGA and negative EMA have a low rate of celiac disease compared to those who are tTGA-positive and EMA-positive. Confirmation with EMA is advised when tTGA is performed as a first-level screening for suspected celiac disease.

Background: Ovarian vein embolization was recently suggested as the preferred treatment for chronic pelvic pain syndrome.

Objective: To evaluate the technical feasibility, complications and early clinical and radiographic results of ovarian vein embolization in women with pelvic pain syndrome.

Methods: Percutaneous transcatheter ovarian vein embolization with coils was performed in six patients aged 27–53 years who presented with pelvic pain syndrome. All had lower abdominal pain, and pelvic varicosities were found on Doppler ultrasound and retrograde ovarian vein venography. Embolization was done unilaterally in three patients (on the left side) and bilaterally in three. Mean follow-up by telephone questionnaire was 7.3 months.

Results: The procedure was technically successful in all patients. Two patients reported partial relief of symptoms (33.3%) and three had complete relief (50%), for a total of 5 patients (83.3%) with some measure of improvement. There were no complications following the procedure.

Conclusions: Percutaneous transcatheter ovarian vein embolization seems to be safe and feasible for the treatment of pelvic pain syndrome. The procedure is performed on an outpatient basis and is well tolerated by patients.

Background: We treated two patients diagnosed with legionellosis and simultaneous Rickettsia conorii co-infection.

Objectives: To report the clinical and laboratory characteristics of this unusual combination, and to describe the execution and results of our environmental and epidemiologic investigations.

Methods: Serial serologic testing was conducted 1, 4 and 7 weeks after initial presentation. Water samples from the patients’ residence were cultured for Legionella. Follow-up cultures were taken from identical points at 2 weeks and at 3 months after the initial survey.

Results: Both patients initially expressed a non-specific rise in anti-Legionella immunoglobulin M titers to multiple serotypes. By week 4 a definite pattern of specifically elevated IgG[1] titers became apparent, with patient 1 demonstrating a rise in specific anti-L. pneumophila 12 IgG titer, and patient 2 an identical response to L. jordanis. At 4 weeks both patients were positive for both IgM and IgG anti-R. conorii antibodies at a titer ³ 1:100. Heavy growth of Legionella was found in water sampled from the shower heads in the rooms of both patients. Indirect immunofluorescence of water cultures was positive for L. pneumophila 12 and for L. jordanis.

Conclusions: Although most cases of community-acquired Legionella pneumonia in our region appear simultaneously with at least one other causative agent, co-infection with R. conorii is unusual and has not been reported to date. This report illustrates the importance of cooperation between clinicians and public health practitioners.

Background: Venous thromboembolic diseases are treated initially with low molecular weight heparin followed by oral coumarins.

Objectives: To investigate an orally available direct thrombin inhibitor for the acute treatment of venous thromboembolism as well as for prophylaxis of recurrent events.

Methods: The direct thrombin inhibitor ximelagatran was compared with subcutaneous LMW[1] heparins followed by oral warfarin in a double-blind randomized prospective multicenter trial in patients with acute VTE[2]. A pharmacokinetic study was performed in the VTE patients. For assessing the prevention of recurrent VTE, double-blind prospective randomized studies were conducted as follows: a) ximelagatran compared to warfarin for 6 months, and b) prolonged anticoagulation of ximelagatran vs. placebo for 18 months after termination of 6 months coumarin therapy.

Results: Two dose-finding studies and the pharmacokinetic analysis of ximelagatran in acute VTE were completed. About 2,500 patients were randomized to investigate 2 x 36 mg ximelagatran versus 2 x 1 mg/kg body weight enoxaparin followed by warfarin. The study hypothesized that the efficacy was equal in both treatment regimens for recurrent VTE documented by objective methods. The second study, with 1,234 patients, aimed to demonstrate a reduced incidence of recurrent thromboembolic events documented by objective methods after 18 months of treatment with 2 x 24 mg ximelagatran daily compared to placebo.

Conclusion: These large-scale clinical trials will soon yield the results of the comparison between oral ximelagatran and subcutaneous LMW heparin for treatment of acute VTE, and of warfarin for prophylaxis of recurrent events for 6 months and for a prolonged prophylaxis for another 18 months.

Background: Fine-needle aspiration is a widely accepted method in the preoperative evaluation of head and neck tumors. However, its effectiveness in the interpretation of salivary gland disorders is controversial.

Objectives: To evaluate the effectiveness of FNA[1] as a preoperative diagnostic tool of parotid lesions.

Methods: Reports of 52 FNA from various parotid gland lesions were compared with the final pathologic diagnoses.

Results: We noted 31 true-positive, 5 true-negative and 16 false-negative results. There were no false-positive FNA reports. The calculated sensitivity, specificity and accuracy of FNA diagnosis in this study were 66%, 100%, and 69.2% respectively.

Conclusions: The high rate (30.8%) of false-negative FNA results was partly explained by sampling errors, therefore specificity of the procedure could be improved by the precise selection of a representative aspiration site.

Background: The majority (n = 445) of the Israeli and Palestinian fatal victims of the El Aqsa Intifada was examined at the National Center of Forensic Medicine in Tel Aviv. Analysis of the trauma sustained and the anthropologic profile of both the victims and the perpetrators elucidates the trends and contrasts them with the phenomenon in the past.

Objectives: The purpose of the forensic investigation of mass casualty incidents is manifold: establishing the minimal number of individuals involved, identifying the victims and perpetrators, collecting material evidence, and determining the modus operandi.

Methods: The postmortem examination includes external description of the bodies and their injuries, photo-documentation, and sampling of tissues. Radiography, dental examination, and a ten-print card of each cadaver are also recorded.

Results: The modus operandi of the current Intifada is somewhat different from that of the previous wave of terrorism and includes more road shootings and vehicular terrorism. In addition, three suicide bombers using explosive devices detonated within crowded areas were young women, and the age of the perpetrators has increased from up to 35 years to individuals as old as 47, thus greatly enlarging the potential number of suicide terrorists. Virologic and biologic tests have been introduced to examine the tissues of the suicide bombers since they are possible sources of contagion to the wounded victims.

Conclusion: The results of the medico-legal investigation of victims and perpetrators of terrorism enable us to establish the modus operandi and the profile of potential perpetrators, which can help in the prevention of similar attacks. Documentation of the different types of injuries in fatal victims of explosion and shooting contributes to improving the awareness of the medical staff treating the wounded of similar attacks. Further investigation into the reliability of virologic and biologic tests conducted on postmortem tissue is recommended.

Severe combined immunodeficiencies represent a heterogeneous group of hereditary defects of the immune system that affect both T and B cells and whose etiology has only recently begun to be understood. A portion of these SCID patients bear a defect in either of the two recombination-activating genes, Rag-1 or Rag-2, while others have mutations in a newly identified gene, Artemis. Omenn syndrome is an unusual severe immunodeficiency with T cells but no B cells, and peculiar features also due to a defect in Rag-1 or Rag-2 genes. All these three forms are characterized by an impairment of the VDJ recombination, the process that insures the somatic diversification of immunoglobulin and T cell receptor-encoding genes. Recent findings have enabled us to better understand the pathophysiology of these three immunodeficiencies, which affect the V(D)J recombination process to a different extent and in different ways.

Background: The rapidly increasing costs of healthcare pose a major challenge to many governments, particularly those of developed countries. Health policy makers in some Western European countries have adopted the policy of a strong primary healthcare system, partly due to their recognition of the value of primary care medicine as a means to restrain costs while maintaining the quality and equity of healthcare services. In these countries there is a growing comprehension that the role of the family physician should be central, with responsibility for assessing the overall health needs of the individual, for coordination of medical care and, as the primary caregiver, for most of the individual’s medical problems in the framework of the family and the community.

Objectives: To describe primary care physicians in Israel from their own perception, health policy makers' opinion on the role PCPs should play, and patients' view on their role as gatekeepers.

Methods: The study was based on three research tools: a) a questionnaire mailed to a representative sample of all PCPs employed by the four sick funds in Israel in 1997, b) in-depth semi-structured interviews with key professionals and policy makers in the healthcare system, and c) a national telephone survey of a random representative sample of patients conducted in 1997.

Results: PCPs were asked to rank the importance of 12 primary functions. A total of 95% considered coordination of all patient care to be a very important function, but only 43% thought that weighing economic considerations in patient management is important, and 30.6% thought that 24 hour responsibility for patients is important. Also, 60% of PCPs have undergone specialty training and 94% thought that this training is essential. With regard to the policy makers, most preferred highly trained PCPs (board-certified family physicians, pediatricians and internists) and believed they should play a central role in the healthcare system, acting as coordinators, highly accessible and able to weigh cost considerations. Yet, half opposed a full gatekeeper model. They also felt that the general population has lost faith in PCPs, and that most have a low status and do not have adequate training. Regarding the patients’ viewpoint, 40% preferred that the PCP function as their “personal physician” coordinating all aspects of their care and fully in charge of their referrals; 30% preferred self-referral to sub-specialists, and 19% preferred their PCP to coordinate their care but wanted to be able to refer themselves to specialists.

Conclusions: In order to maintain high quality primary care, it is important that all PCPs have board certification. In addition, PCP training systems should emphasize preventive medicine, health promotion, health economy, and cost-effectiveness issues. Efforts should be make to render PCPs a central role in the healthcare system by gradually implementing the elements of the gatekeeper model through incentives rather than regulations.
 

Although a depressive state is known to occur following the resolution of an acute psychotic episode, little research has investigated its etiology, course, prognosis and treatment. Very often the depression is mistaken for an extrapyramidal­like syndrome — the secondary effect of antipsychotic medica­tion - as a sense of inevitability assails both the patient and therapist. Post-psychotic depression, far from being an obscure and undefined clinical picture, has the characteristics of a clear-cut syndrome. Nevertheless, it was only recently referred to as a distinct entity in psychiatric classification systems. As a result, different researchers used varying criteria for the definition of the phenomenon, and the data collected in the different studies are therefore difficult to compare. We present a critical review of the data published to date, with emphasis on the importance of early recognition and treatment of post-psychotic depression.

Background: In Israel the pediatric emergency room functions as an urgent primary care clinic in addition to dealing with life-threatening situations. Due to health insurance stipulations, most patients come to the PER with a referral from the community clinic. The relationship between the referring physician’s expectations and the subsequent management of the referred patient in the PER is not well defined.

Objectives: To evaluate the relationship between the expectations of the primary care physician and the management of referred patients in the PER, assess the type of information provided by the referring physician, and examine the effect of additional information obtained from the referring physician on patient management in the PER.

Methods: We reviewed the records of patients presenting at the PER with referrals from primary care physicians as well as additional information obtained by telephone interviews with the referring physicians.     

Results: The expectations of the referring physicians were not fully documented in the referral form. The PER responded to the patient as if the PER was the initial contact. There was no significant difference in the response of PER physicians with or without additional information from the referring physicians.

Conclusions: The PER acts as an independent unit with no obligation to satisfy the expectations of the referring physicians. The relationship between the PER and the referring physicians needs to be clarified. Guidelines and structured PER referral forms should be implemented in all primary care clinics to improve patient management and communication between health providers.
