Israel Medical Association Journal

Background: Complementary and alternative medical care has gained increasing popularity in western societies in recent years.

Objectives: To provide a cross-sectional and temporal (2000 vs. 1993) analysis of the use of complementary and alternative medicine in Israel.

Methods: The subjects studied represented the Israeli Jewish urban population aged 45–75 years. Full sit-down interviews were conducted with 2,003 respondents in 1993 and 2,505 respondents in 2000.

Results: For 1993, 6% of the population reported on consultations with CAM[1] providers during the previous year. For 2000, that proportion increased to 10%. Being a woman, having higher education, enjoying better economic status, being younger, living in a big city, and being dissatisfied with specialists’ care were all positively related to the use of non-conventional medicine, particularly in 2000. In both years, more than 50% of the consultations were with acupuncturists and homeopaths. However, chiropractors have doubled their market shares, and lower back pain became the leading problem for which care was sought. The main reason for consulting CAM was a reluctance to use too many drugs or to undergo an invasive procedure. However, a significant proportion of the users continue to use conventional medicine concurrently. Seventy-five percent in 2000 and 60% in 1993 reported that the treatment helped.

Conclusions: Between 1993 and 2000, CAM in Israel changed from an infant industry into a mainstream medical commodity, reflected in both prevalence and different patterns of consumption.

Background: Seroepidemeliogic surveys have provided valuable information on the prevalence and incidence of herpes simplex virus-2 infection in general and in selected populations.

Objective: To review the reliability of traditional diagnostic approaches in herpes simplex virus-2 infection.

Methods: In this cross-sectional study, 472 patients attending a clinic for sexually transmitted disease in 1998-1999 were evaluated for HSV-2 infection through collection of epidemiologic and clinical data.

HSV-2 infection was confirmed by the presence of specific Viral glycoprotein, gG-2, antibody in sera.

Results: The seroprevalence of HSV-2 among clinic attendees was 9.33%. Of these attendees only 22% presented with or reported a history of typical vesicular lesions in the genital area. Infection rate was  higher in patients with multiple sex partners (20.8% vs. 8.7%, P< ( 0.0023 in individuals aged 30 or older (12.6 vs. 6.4%, P = 0.03) and  in the Israeli Jewish population as compared to the Israeli Arab population (11.1% vs. 2.4%, P ~ 0.01). Females with multiple sex partners exhibited higher rates of infection than did their male counterparts (50 vs. 16.1%, P < 0.0275(.

Conclusion: The findings support the need for HSV-2 serologi  testing in patients presenting to STD clinics even when typical genital  lesions are not evident but where risk factors for HSV-2 infection are  identified.
 

Background: Complementary medicine is gaining popularity, yet medical school curricula usually ignore it.

Objectives: To determine whether senior medical students are interested in learning principles of complementary or alternative medicine, to check their degree of familiarity with it, and to suggest a format for such studies in the medical curriculum.

Methods: Senior medical students (n = 117) were surveyed by an anonymous questionnaire.

Results: Seventy-nine percent of the senior medical students were interested in studying complementary or alternative medicine in medical school, and 65% were interested in applying these techniques to treat patients. Eighty-seven percent of students were familiar with some techniques of complementary medicine.

Conclusions: Senior medical students are interested in studying complementary and alternative medicine in medical school and in applying these techniques in practice.
 

Background: Non-gonococcal urethritis is the most common clinical diagnosis for men seeking care at sexually transmitted disease clinics.

Objective: To identify the pathogens involved in NGU[1] among males attending an Israeli STD clinic.

Methods: During 19 months spanning September 1996 to July 1998 we investigated a cohort of 238 male patients attending the Bnai Zion Medical Center STD[2] clinic with a clinical presentation of urethritis. Intraurethral swab specimens were tested for Neisseria gonorrhea, Ureaplasma urealyticum, Mycoplasma hominis, and Trichomonas vaginalis by culture and for herpes simplex virus by antigen detection. First voiding urine for Chlamydia trachomatis was done by polymerase chain reaction. The specific seropositivities of HSV[3] types 1 and 2 were tested by enzyme-linked immunosorbent assay.

Results: From among 238 males with dysuria or urethral discharge an etiology for urethritis was found for 71 (29.8%). N. gonorrhea was recovered in only three men (4.2%). In the remaining 68 NGU patients C. trachomatis (35/68, 51.5%) and U. urealyticum (31/68, 45.6%) were the most common infecting and co-infecting pathogens (P < 0.0001). M. hominis and T. vaginalis were found in 9/68 (13.2%), and 1 patient, respectively. HSV was recovered from the urethra in 7/68 males (10.3%) – 3 with HSV-1, 2 with HSV-2, and 2 were seronegative for HSV. None of these males had genital lesions. Although a single etiologic agent was identified in 45/68 infected men (66.2%), co-infection was common: 2 organisms in 15 (22%) and 3 organisms in 8 (11.8%).

Conclusion: C. trachomatis and U. urealyticum were the most common infecting and co-infecting pathogens in this cohort of men with NGU. Unrecognized genital HSV infections are common in males attending our STD clinic and symptomatic shedding of HSV occurs without genital lesions. Still, the microbial etiology in this group remains unclear in many patients despite careful microbiologic evaluation.

Background: The use of an automated biopsy system for renal biopsy has recently gained popularity, but its safety in single functioning kidneys is unclear.

Objective: To report our experience with the automated system for closed renal biopsy during a 5 year period.

Methods: Eighty-five patients underwent percutaneous native renal biopsy with the automated biopsy gun (16G needle) under real-time ultrasound. They were chronologically divided into two groups: 41 patients (group A), using an older ultrasound machine; and 44 patients (group B), using a newer ultrasound machine. Nine patients biopsied with a manual 14G Tru-cut needle served as the control (group C).

Results: The number of "attempted" passes at the kidney was 4.0 ± 0.1 in group B, 4.7 ± 0.3 in group A (P < 0.05 vs. group B), and 5.8 ± 0.5 in group C (P < 0.01 vs. group B). The number of successful passes did not differ (3.3 ± 0.1, 3.3 ± 0.1, 3.1 ± 0.2). The ratio of "attempted/successful" was 1.28 ± 0.07 in group B, 1.95 ± 0.38 in A, and 1.90 ± 0.21 in C (P < 0.01 vs. B). The number of glomeruli obtained was similar in the three groups. Adequate tissue was obtained in 95%, 98%, and 100%, respectively. Hemoglobin decreased by 4.3 ± 1.1% in group B, 6.9 ± 1.3% in group A, and 11.3 ± 1.8% in group C (P < 0.05 vs. B). Perinephric/subcapsular hematoma occurred in 5 patients (11.4%) in group A (2 taking aspirin), in 2 patients (4.9%) in group B, and in none in group C. The necessity for blood transfusion post-biopsy was similar in all groups. Four of five patients with single functioning kidneys (one in group A and four in group B) had uneventful biopsies, and adequate tissue was obtained in three.

Conclusions: The use of the automated biopsy gun is effective, safe and has a low rate of major complications. It may be used safely in single functioning kidneys.

Background: The bladder tumor antigen stat is a simple and fast one-step immunochromatographic assay for the detection of bladder tumor-associated antigen in urine.

Objectives: To evaluate the BTA[1] stat in non-bladder cancer patients in order to identify the categories contributing to its low specificity.

Methods: A single voided urine sample was collected from 45 patients treated in the urology clinic for conditions not related to bladder cancer. Each urine sample was examined by BTA stat test and cytology.

Results: The overall specificity of the BTA stat test was 44%, which was significantly lower than that of urine cytology, 90%. The false positive rates for BTA stat test vary among the different clinical categories, being highest in cases of urinary tract calculi (90%), and benign prostatic hypertrophy (73%). Exclusion of these categories from data analysis improved BTA stat specificity to 66%.

Conclusions: Clinical categories contributing to low BTA stat specificity can be identified, and their exclusion improves the specificity of this test.

Background: Alternative medicine use is increasing worldwide and the associated expenditures are significant. In Israel 19% of patients who consulted their family physician had also sought treatment by an alternative medicine practitioner.

Objectives: To explore the correlation between different modalities of healthcare utilization, health behavior, and health belief among adult members of a kibbutz. This unique study population enabled the use of a simplified quantitative model due to the minimal individual differences in cost and access.

Methods: Healthcare utilization data were obtained for 220 kibbutz members aged 15–70 years from patient medical files and self-administered questionnaires over a 45 month period. Patient visits to the family practitioner and other specialist physicians were tallied, and individuals reported alternative medicine consultations during the previous year. Multiple regression analysis was used to control for age, chronic disease, and other background characteristics.

Results: The mean number of patient FP visits was 3.6 per patient per year. Women and chronic disease sufferers visited the doctor more frequently. A patient’s number of FP visits and other specialist physician visits were closely correlated, with each specialist physician consult resulting in an additional 0.64 FP visit for a given individual (P=0.007). Our analysis indicated that self-reported alternative therapy utilization was positively associated with the number of FP visits; patients reporting alternative therapy use visited their primary care physician once additionally per year (P=0.03). Low self-rated health status was correlated with increased likelihood of alternative therapy use (borderline significance).

Conclusion: These results suggest that a patient who seeks treatment from one type of healthcare practitioner will seek out other practitioners as well. This study supports the notion that unconventional therapies are used in conjunction with, rather than instead of, mainstream medical care.
