Background: Many medical school curricula include training for ethical considerations, legal comprehension, implementation of patients' rights, awareness of cultural differences and communication skills (ELCE).

Objectives: To explore medical students' perceptions of their ELCE training during the clinical phase as well as the relationship between humanistic practice skills' experiences and the quality of clinical training.

Methods: A cross-sectional survey was carried out in two cohorts during their clinical year period at Tel Aviv University's Sackler Faculty of Medicine at the end of their internal medicine and surgery clerkships in the 2002 academic year. The research tool was an 18 item Likert-type questionnaire (ELCEQ), based on the literature of biomedical ethics, legal aspects and behavior of practice skills. The content validation of the questionnaire was established by consulting experts among the school's faculty. It was circulated among the students by representatives of the Unit of Medical Education.

Results: The response rate was 88%. Students reported only a few opportunities for gaining experience in humanistic practice skills. A weak correlation was found between students' assessment of the quality of clinical training and their experiences in humanistic practice skills.

Conclusions: A wider and more relevant range of active experiences in humanistic practice skills should be available to students during the clerkships. Correspondingly, there is a need for the clinical faculty to find innovative ways to internalize their task as role models and ensure that students acquire and are able to practice those skills.
 

Background: The management of diabetes in preschool children poses unique difficulties for both the families and the medical team.

Objective: To test the feasibility and safety of insulin pump therapy in the 1–6 year age group in order to improve quality of life and metabolic control.

Methods: The study group comprised 15 type 1 diabetic children aged 1–6 years old (mean ± SD, 3.8 ± 1.2 years) from three diabetes centers. Insulin pump therapy was applied for 12 months. Data, including insulin dose, hemoglobin A1c, hypoglycemic events, as well as scores on the Diabetes Quality of Life Measure Questionnaire and the Diabetes Treatment Satisfaction Questionnaire, were collected and compared with the multiple daily injections treatment prior to entry into the study.

Results: HbA1c[1] was measured at the beginning of the study and at 2, 4, 8 and 12 months later; the respective levels (mean ± SD) were 8.82 ± 0.98, 8.45 ± 1.05, 8.37 ± 0.85, 8.32 ± 0.71, 8.18 ± 0.90%. HbA1c measurements after 12 months were significantly lower than at the beginning of the study (P < 0.05). There were no significant differences in insulin dose and the total number of hypoglycemic events. In both the DQOL[2] and DTSQ[3] scales there were significant differences in scores in favor of the insulin pump period (43.7 ± 8.0 versus 33.7 ± 7.9, P < 0.001; and 10.9 ± 2.3 versus 14.5 ± 2.3, P < 0.001), respectively.

Conclusions: For very young diabetic children, insulin pump therapy improves quality of life and is feasible and safe. It should be considered as an optional mode of therapy for this age group.

Background: Eyes scheduled for posterior segment surgery may have cataract, which obscures the visualization of the retina. Surgery may be carried out either by a two-step procedure: i.e., removal of the cataract followed later by posterior segment surgery; or it may be done in a single session: i.e., combined surgery of both the anterior and posterior segments.

Objective: To evaluate the outcomes of combined surgery by phacoemulsification and vitrectomy.

Methods: We retrospectively reviewed the records of 42 patients with coexisting cataract and vitreoretinal disease who underwent combined surgery by phacoemulsification and pars plana vitrectomy at one session.

Results: Indications for surgery were vitreous hemorrhage in 71.4%, retinal detachment in 11.9%, macular hole in 11.9%, and epiretinal membrane in 4.8%. There were no significant intraoperative complications.The main early postsurgical complications were fibrinous formation in 11.9%, elevated intraocular pressure in 23.8%, and recurrent vitreous hemorrhage in 9.5%. There were a few late complications related to phacoemulsification: posterior synechia in 9.5%, posterior capsular opacification in 7.1%, and dislocating intraocular lens in 4.8%. Recurrent retinal detachment occurred in five eyes and rubeoisis iridis in one. Visual acuity was improved in 85.8%, stable in 7.1% and worse in 7.1%.

Conclusions: Phacoemulsification performed at the time of posterior segment surgery enables good visualization during the vitrectomy, facilitates surgery, and is associated with only minor complications. In cases with cataract and vitreoretinal diseases, combined surgery by phacoemulsification and vitrectomy in one session may be considered.
 

Background: Sulfur mustard and VX are potent chemical warfare agents that penetrate rapidly through the skin, causing severe prolonged injuries and sometimes death.

Objectives: To develop a topically applied pretreatment that will act as a barrier and prevent the absorption of these agents through the skin, reducing morbidity and saving life.

Methods: Several formulations were developed and tested in preclinical animal studies in pigs. The protecting cream was applied as a single application (0.5–1 ml/100 cm²) prior to exposure (10 minutes to 12 hours) to sulfur mustard or VX. Assessment of sulfur mustard-induced skin damage was based on clinical and histologic evaluations. When tested against VX, clinical signs and blood cholinesterase activity were monitored. At the final stage of development, safety studies were conducted in animals and in human volunteers.

Results: The formulation that gave the best results, coded IB1 (under patent application), provided significant protection against a 1 hour exposure to sulfur mustard (droplets or vapor). All the pigs pretreated with IB1 cream survived a 1–4 hour challenge of 2xLD₅₀ VX and did not exhibit any overt clinical signs. Protection was exhibited even when the cream was applied 12 hours (single application) prior to exposure. IB1 was found to be non-irritating in animals and humans. No adverse effects were found in a Phase I clinical study in young healthy volunteers when the cream was applied to around 20% of the skin surface (results presented elsewhere).

Conclusions: IB1 cream has been shown to be a safe and effective topical skin protectant against the chemical warfare agents sulfur mustard and VX.

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: Menopause affects women's health and well-being, but their knowledge of proper care and maintenance is uncertain.

Objective: To assess the attitude and approach of the healthy, low risk, postmenopausal population in Israel to personal healthcare and menopause.

Methods: The study population comprised 500 menopausal women attending community outpatient primary care clinics. All women completed a 20-item questionnaire covering personal healthcare habits, lifestyle, knowledge about menopause, and attitude and approach to menopause and use of hormone replacement therapy.

Results: The patients' mean body mass index was 25.8 ± 4.1 kg/m²; more than half the women were overweight, 28% percent engaged in regular sports activity, nd 11.2% smoked; 74% had a positive attitude towards their age; 60% underwent yearly screening mammography; 74% have had Pap smear and 86% had lipid profile measurements during the last year; self-examination of the breast was regularly performed by only 49%. HRT[1] is currently being used by 27% and had been used in the past by another 16%. The primary reasons for stopping therapy were irregular bleeding in 38% and apparent ineffectiveness in 35%. There was a positive significant correlation between level of education and both undergoing regular medical screening and engaging in regular sports activity. HRT current utilization was negatively associated with age and being a housewife.

Conclusions: A relatively high percentage of the study population safeguards its health and regularly uses HRT. We believe that stronger efforts are needed in Israel to promote good healthcare habits and positive attitudes toward menopause and HRT use.

Background: Prematurity remains the most significant cause of neonatal morbidity and mortality. Knowing which group of women is at risk for developing preterm labor will define a target population for better prenatal care and prevention modalities.

Objective: To examine whether preterm delivery rates are associated with ethnicity, age, parity, and style of living.

Methods: We conducted a longitudinal case series examining obstetric and demographic data of 17,493 deliveries that occurred between June 1994 and May 1999. All deliveries were performed in the obstetric department of HaEmek Medical Center (Afula, Israel), which serves as a referral center. The main outcome measures were preterm delivery, as related to the women's ethnicity, age parity, and style of living ± namely, town, village, or kibbutz.

Results: The overall preterm delivery rate was 8.5%. The preterm delivery rate in non-Jewish women (10.5%) was higher than in Jewish women (7.1%) (P < 0.00001). The preterm delivery rate in women younger than 20 or older than 40 (12.5%) was much higher than in women between the ages of 21 and 40 (8.0%) (P< 0.00001). Grand-multipara women (>8) had a higher preterm delivery rate (13.8%) than less parous women (8.5%) (P < 0.012). Style of living was also associated with the preterm delivery rate (P< 0.00001): kibbutz 5.5%, Jewish towns 7.8%, non-Jewish towns 8.7%, Jewish villages 6.7%, and non-Jewish villages 11.0%.

Conclusions: Style of living, ethnicity, age and parity are statistically significant risk factors for preterm delivery in our area. These factors provide a more definable target population for better prenatal care.
