Background: With market failures characterizing the health care sector, societies are continuously searching for ways to achieve an efficient and fair allocation of resources. A natural source of opinion on the desired allocation of health resources is the public. In fact, several governments have recently involved the general public in decisions about resource allocation in their health systems.

Objectives: To investigate the views of the Israeli Jewish public aged 45-75 on horizontal equity in medical care; specifically, the characteristics (including a lottery) for determining which of two individuals with similar medical need should be treated first, against a background of limited resources.

Methods: A sample of 2,030 individuals was chosen to represent a population of about 800,000 urban Jewish Israelis aged 45–75. Data were collected in face-to-face full sit-down interviews by trained interviewers between October 1993 and February 1994.

Results: The three most preferred prioritizers were chances of recovery, number of dependants, and young age. Random prioritization was preferred by only 8% of the population. Age, level of education and religiosity were the main characteristics associated with the choice.

Conclusions: The Israeli adult public does not favor strict horizontal equity in health care. As in other social programs, “equals” were defined in a multi-criteria manner, based on both medical need and other personal characteristics. The preferred prioritizers seem to reflect universal tastes and cast doubt on the traditional distinction between efficiency and equity and between horizontal and vertical equity when applied to health care.
 

Background: *Previous descriptive studies have demonstrated the problematic nature of physicians' attitudes toward battered women. However, little empirical research has been done in the field, especially among the various medical specialties.

Objectives: To compare the approach and feelings of competence regarding the care of battered women between primary care and non-primary care physicians. The non-primary care physicians who are likely to encounter battered women in the ambulatory setting are gynecologists and orthopedists.

Methods: A self-report questionnaire formulated for this study was mailed to a random sample of 400 physicians working in ambulatory clinics of the two main health maintenance organizations in Israel (300 primary care physicians, 50 gynecologists and 50 orthopedists).

Results: In both physician groups, treating battered women tended to evoke more negative emotional states than treating patients with infectious disease. The most prevalent mood state related to the management of battered women was anger at her situation. Primary care physicians experienced more states of tension and confusion than non-primary care physicians and had lower perceived self-efficacy and self-competence in dealing with battered women.

Conclusions: Though both physician groups exhibited negative feelings when confronting battered women, the stronger emotion of the primary care physicians may indicate greater sensitivity and personal awareness. We believe that more in-service training should be introduced to help physicians at the undergraduate and postgraduate levels to cope both emotionally and professionally with these patients.

Background: First-degree relatives of colorectal cancer patients are the largest groups of individuals at increased risk for colorectal cancer.

Objective: To assess the knowledge, attitudes and behavior to disease prevention and colorectal cancer screening among first-degree relatives of colon cancer patients.

Methods: A descriptive, point-prevalence epidemiological study was conducted among 215 first-degree relatives of survivors of colorectal cancer in the southern (Negev) region of Israel. Variables included perceived health status, knowledge about cancer screening, compliance rates with colorectal cancer screening, and interest in participation in early detection programs in the future.

Results: The mean age of the respondents was 47.9111.2 years, and 54% were males. Only 58 (27%) remembered having been encouraged to undergo an early detection test. In the previous year only 15% underwent fecal occult blood tests, while 9% had a barium enema and 14% an endoscopic examination of the colon by sigmoidoscopy or colonoscopy. A total of 49% of the asymptomatic respondents were unaware of recommendations for screening, and only 38.3% expressed any interest in participating in early detection programs in the future. Only 19% of respondents over the age of 50 and 8% of respondents over age 60 were interested in participating compared with 49% under the age of 50 (P0.0001).

Conclusion: A minority of first-degree relatives of colorectal cancer patients reported having been counseled to undergo screening, although most had seen their family physician in the previous 3 years. Primary care physicians should be more active in informing at-risk patients and encouraging them to undergo periodic screening.

Background: Familial dysautonomia is a genetic disease in which there is a defect in the autonomic and sensory nervous systems. These systems have a major role in the reproductive system.

Objective: To study the inter-relationship of autonomic and sensory dysfunction and gynecological function.

Methods: The gynecological histories of 48 women with familial dysautonomia were analyzed retrospectively. Their mean age was 22.25 years (range 12-47). Thirty-three women (65%) were available for further questioning and investigation of hormonal status.

Results: Menarche had occurred in 32 of the 48 (66.7%). Their average age of menarche was significantly delayed as compared to their unaffected mothers (15.5 vs. 13.6 years respectively, P=0.002). The most prominent finding was the very high prevalence, 81.2%, of premenstrual symptoms. Seven of 26 had premenstrual syndrome symptoms of dysautonomic crisis. Blood sex hormone levels were normal in 27 of the 33 patients studied. None reached natural menopause. One patient had adenomyosis, and another, dysgerminoma. Three patients became pregnant and delivered healthy infants.

Conclusion: Menarche is delayed in women with FD, and the physiological monthly hormonal fluctuations may disturb autonomic homeostasis sufficiently to precipitate dysautonomic crisis.

Background: Data regarding the epidemiology of secondary pulmonary hypertension are scanty.

Objectives: To describe the spectrum and relative incidence of background diseases in patients with significant secondary PHT.

Methods: We identified 671 patients with systolic pulmonary artery pressure of 45 mm Hg or more from the database of the echocardiographic laboratory. Their background diseases were recorded and classified into three subgroups: cardiac, pulmonary and pulmonary vascular disease without pulmonary parenchymal disease. Age at the first echocardiographic study, gender and systolic PAP values were recorded. Data between the three subgroups were compared.

Results: The mean age of the patients was 6515 years, mean systolic PAP 6114 mm Hg and female:male ratio 1.21:1. At the time of diagnosis 85% of the patients were older than 50. PHT was secondary to cardiac disease in 579 patients (86.3%), to PVD without PPD in 54 patients (8%) and to PPD in only 38 patients (5.7%). Mean age and mean systolic PAP did not differ significantly among the three subgroups. There was a significantly higher female: male ratio in patients with PVD without PPD compared with cardiac or pulmonary diseases (1.7:1 vs. 1.2:1 and 1.7 vs. 0.8:1 respectively, P0.05).

Conclusions: The majority of patients with significant PHT are elderly with heart disease. PVD without PPD and chronic PPD are a relatively uncommon cause of significant PHT. Since the diagnosis of PHT is of clinical significance and sometimes merits different therapeutic interventions, we recommend screening by Doppler echocardiography for patients with high risk background diseases.

Background: The frequent coexistence of two or more sexually transmitted diseases in one patient has been reported in non-dermatological literature, mostly in languages other than English. Identification of Ureaplasma urealyticum, Chlamydia trachomatis and Mycoplasma hominis in men with other STDs is important, since these bacteria have been implicated in a variety of diseases such as non-gonococcal urethritis, premature rupture of fetal membranes, and infertility in female sexual partners of these patients.

Objective: To assess the frequency of concomitant STD, particularly urethral colonization of U. urealyticum, C. trachomatis and M. hominis, in men consulting for suspected STD-related symptoms.

Methods: All patients attending our dermatology clinic for STD-related symptoms during a 12 month period in 1996–97 underwent systematic clinical and laboratory screening for syphilis, gonorrhea, NGU, prostatitis, genital herpes simplex infection, Condyloma acuminatum, urethral carriage of U. urealyticum, C. trachomatis and M. hominis, as well as serological screening for HIV, and hepatitis B and C infections.

Results: A total of 169 men with STD-related symptoms were enrolled in the study. The following clinical diagnoses were established: NGU in 109 men, C. acuminatum in 40, genital herpes simplex in 10, prostatitis in 7, latent syphilis in 6, primary syphilis in 1, and Behcet’s disease in 1. No clinical evidence of STD was found in 13 patients. Of the 169 patients, 39 (23%) had two or more concomitant STDs, of whom 27 (69%) had C. acuminatum associated with one or more of the urethral pathogens. A positive U. urealyticum culture was found in 67.5% (27/40) of the men with C. acuminatum as compared to 42% (40/96) among the patients with NGU who did not have C. acuminatum (P=0.004, X² test). Conversely, the prevalence of C. acuminatum among patients positive for U. urealyticum was significantly higher than the prevalence among those who were negative – 27/75 (36%) vs. 13/94 (14%), P<0.0009, X² test. About half of the U. urealyticum-positive patients with C. acuminatum had no clinical signs or symptoms of urethritis.

Conclusion: Our findings suggest that patients with C. acuminatum should be assessed for U. urealyticum carriage and, when identified, their sexual contacts should be actively sought and treated.

Background: Carbohydrate malabsorption of lactose, fructose and sorbitol has already been described in normal volunteers and in patients with functional bowel complaints including irritable bowel syndrome. Elimination of the offending sugar(s) should result in clinical improvement.

Objective: To examine the importance of carbohydrate malabsorption in outpatients previously diagnosed as having functional bowel disorders, and to estimate the degree of clinical improvement following dietary restriction of the malabsorbed sugar(s).

Methods: A cohort of 239 patients defined as functional bowel complaints was divided into a group of 94 patients who met the Rome criteria for irritable bowel syndrome and a second group of 145 patients who did not fulfill these criteria and were defined as functional complaints. Lactose (18 g), fructose (25 g) and a mixture of fructose (25 g) plus sorbitol (5 g) solutions were administered at weekly intervals. End-expiratory hydrogen and methane breath samples were collected at 30 minute intervals for 4 hours. Incomplete absorption was defined as an increment in breath hydrogen of at least 20 ppm, or its equivalent in methane of at least 5 ppm. All patients received a diet without the offending sugar(s) for one month.

Results: Only 7% of patients with IBS and 8% of patients with FC absorbed all three sugars normally. The frequency of isolated lactose malabsorption was 16% and 12% respectively. The association of lactose and fructose-sorbitol malabsorption occurred in 61% of both patient groups. The frequency of sugar malabsorption among patients in both groups was 78% for lactose malabsorption (IBS 82%, FC 75%), 44% for fructose malabsorption and 73% for fructose-sorbitol malabsorption (IBS 70%, FC 75%). A marked improvement occurred in 56% of IBS and 60% of FC patients following dietary restriction. The number of symptoms decreased significantly in both groups (P<0.01) and correlated with the improvement index (IBS P<0.05, FC P<0.025).

Conclusions: Combined sugar malabsorption patterns are common in functional bowel disorders and may contribute to symptomatology in most patients. Dietary restriction of the offending sugar(s) should be implemented before the institution of drug therapy.
