A 74-year-old man with an enlarging pleural-based mass that was not a mesothelioma.

Soft tissue sarcomas of the chest wall, also known as primary malignant mesenchymal tumors, may be mistaken for a malignant mesothelioma because of their histologic similarities. Reports of primary pleural sarcomas are exceedingly uncommon. We present an unusual case of a primary pleural sarcoma with unique clinical and histological features not previously seen in any other subtype of pulmonary sarcoma.

Correlations of work, leisure, and sports physical activities and health status with socioeconomic factors: a national study in Israel.

OBJECTIVE: To evaluate levels of physical activities at work, leisure, and sports and to correlate them with socioeconomic and health factors. METHODS: Validated questionnaire administered to a random sample of 406 adults. Items covered demographic data, health status, smoking, and duration, frequency, intensity of physical activities. Indices of physical activity at work, leisure, and sports were analysed. RESULTS: Adults (both sexes) with poor self perceived health status and less than 13 years of education, regardless of their body mass index, perform no or few physical activities during their leisure time. CONCLUSIONS: The correlations of physical activity with socioeconomic and health factors differ significantly for work, leisure, and sports. Physicians should differentiate physical activities by type and intensity during anamneses.

Use of humour in primary care: different perceptions among patients and physicians.

PURPOSE: (1) To explore the frequency with which humorous behaviour and statements occur in family medicine practice in Israel, and (2) to quantitatively assess the correlation between the subjective perceptions of humour in medical encounters between patients and physicians. METHOD: In a cross sectional study, two populations (doctors and patients) were surveyed with paired structured questionnaires completed immediately after primary care practice visits. Two hundred and fifty consecutive encounters from 15 practices were sampled. The physician questionnaire was self administered, and patient questionnaire was administered by a trained research assistant. RESULTS: A mean of 16.7 questionnaires was completed per physician (range 6-20). The physicians reported having used some humour in only 95 encounters (38%), whereas almost 60% of patients agreed with the statement, "The doctor used some humour during the visit". At the same time, for specific encounters, the agreement between patients' perception and physicians' perceptions on the use of humour, although not completely by chance (p = 0.04), is low (kappa = 0.115). Patient characteristics (age, education, gender, family status, mother tongue, self perceived heath status, stress, mood, and expectations) were not related to the degree of agreement between the patients' and physicians' perceptions. CONCLUSION: Humour was used in a large proportion of encounters, independently of patient characteristics. Patients seem to be more sensitised to humour than physicians, probably because of their high stress level during medical encounters. Cultural differences may also play a part. Physicians should be made aware of this magnifying effect, and the issue should be discussed in medical schools.

Comparison of efficiency and preference of metal and plastic spacers in preschool children.

BACKGROUND: The metal NebuChamber valved holding chamber (VHC) has gained wide acceptance among children with asthma. Due to its nonelectrostatic properties and larger volume, the 250-mL, metal NebuChamber delivers a greater mass of aerosol to a filter at the mouth compared with the commonly used 150-mL polypropylene AeroChamber VHC. Such in vitro results have been used to suggest that this may provide increased efficacy with the NebuChamber. No comparative efficacy data exist for preschool children with asthma. OBJECTIVE: To compare efficiency and preference of metal and plastic spacers in preschool children. METHODS: Children with mild-to-moderate persistent asthma received 200 microg of budesonide twice daily by NebuChamber or AeroChamber, both with the mask provided in a randomized, 2-month, crossover trial. Symptom diary cards, beta-agonist use, and preference by children and parents were compared. RESULTS: Thirty children (mean +/- SD age, 4.3 +/- 0.3 years) completed the study. There was no difference between the AeroChamber and NebuChamber in clinical efficacy outcomes. There was no difference between the AeroChamber and NebuChamber in parents' view of ease of use, design, acceptability by the children, and overall satisfaction. CONCLUSIONS: Despite a greater total dose delivered to the mouth, the NebuChamber appears no more effective than the AeroChamber and it is not preferred by patients or parents. More parents chose to continue to use the NebuChamber after the study.

Empiric treatment of uncomplicated UTI in women: wasting money when more is not better.

CONTEXT: Trimethoprim-sulfamethoxazole (TMP-SMX) and nitrofurantoin were until recently the two drugs recommended in clinical guidelines in Israel for empiric treatment of uncomplicated urinary tract infection (UTI) in women. OBJECTIVES: The objective of this study is to evaluate the economic impact of physician non-adherence to these recommendations. DESIGN SETTING AND PATIENTS: Data were derived from the electronic patient records of the Leumit Health Fund. Cases of women aged 18 to 75 with a diagnosis of acute cystitis or UTI that were empirically treated with antibiotics from January 2001 to June 2002 were identified. The final sample comprised 7738 physician-patient encounters. The proportion of cases treated with each individual drug was calculated, and the excess expenditure because of non-adherence to guidelines from the perspective of the Health Maintenance Organization (HMO) was evaluated using 5 days of therapy with nitrofurantoin as the reference treatment. RESULTS: TMP-SMX was the most frequently prescribed drug (25.81%), followed by nitrofurantoin (14.71%) representing a 40.52% rate of adherence to the guidelines. Drugs from the fluoroquinolone family were prescribed in 22.82% of cases. Cost of treatment in approximately 70% of the cases exceeded the expected cost of the guideline therapy. CONCLUSIONS: Suboptimal adherence to the guidelines resulted in a significant and avoidable waste of the health plan's resources in both drugs and money.

Longer than recommended empiric antibiotic treatment of urinary tract infection in women: an avoidable waste of money.

CONTEXT: Current Israeli guidelines for the empiric treatment of uncomplicated urinary tract infection (UTI) in women recommend nitrofurantoin for 5 days. Some physicians nevertheless opt for ofloxacin, which should be prescribed for 3 days according to universally accepted guidelines. OBJECTIVE: To evaluate the economic consequences of longer than recommended durations of antibiotic therapy in the empiric treatment of uncomplicated UTI in women. DESIGN, SETTING AND PATIENTS: Data were derived from the electronic records of one of the four health maintenance organizations in Israel. The sample included all women aged 18-75 years who were diagnosed with acute cystitis or UTI from January 2001 to June 2002 and were empirically treated with antibiotics. Of the 7738 patients identified, 1138 received nitrofurantoin and 1054 ofloxacin. The excess expenditure accrued due to longer than recommended therapy with these drugs was evaluated. RESULTS: The rate of adherence was 22.23% for nitrofurantoin (95% CI=19.81%, 24.65%), and 4.08% for ofloxacin (95% CI=2.88%, 5.28%). The average excess expenditure per case was 5.78 USD (US Dollar) with ofloxacin and 3.43 USD with nitrofurantoin, resulting in an annual loss to the health maintenance organizations of approximately 19,000 USD. When extrapolated to the national population of 6.5 million, the loss due to inappropriate treatment of adult women is 190,000 USD. CONCLUSIONS: The lack of adherence to national and international guidelines with regard to the recommended duration of antibiotic treatment of UTI in women resulted in a significant and avoidable waste of health system resources. This study suggests that drug utilization analyses that concentrate solely on the choice of drug may be overlooking important information.

Safety of inhaled corticosteroids delivered by plastic and metal spacers.

BACKGROUND: Because of its non-electrostatic properties the metal Nebuchamber (NC) valved holding chamber (VHC) delivers a greater mass of aerosol to the mouth than the polypropylene Aerochamber (AC) VHC. Delivery of more aerosol to the lungs may also increase systemic absorption of inhaled corticosteroids (ICS) and hypothalamo-pituitary-adrenal (HPA) suppression. METHODS: Thirty children (mean 4.3 (SD 0.3) years) received 200 micro g budesonide twice daily by NC or AC, both with the mask provided, in a randomised, two month crossover trial. Twenty four hour urinary free cortisol (UFC) was determined as a measure of HPA suppression. RESULTS: UFC decreased from 42.3 (7.8) nmol UFC/nmol creatinine control to 26.2 (2.4) (p = 0.06 v control) after AC, and to 24.5 (2.5) (p = 0.04 v control) after NC (p = 0.4 AC v NC). CONCLUSIONS: Despite a greater total dose delivered to the mouth, NC is not associated with greater HPA suppression when using 400 micro g/day budesonide under real life conditions in young children.

Are medical reports on fitness to drive trustworthy?

PURPOSE: Previous studies have shown that physicians often have poor knowledge of the medical restriction on fitness to drive, or submit poor quality medical reports. To determine the reliability of physicians' reports on fitness to drive, the medical data provided on the standard medical fitness form was compared with the additional data collected on repeated assessment. METHODS: A random sample of 100 applicants for a driver's licence aged more than 49 years who submitted the standard medical form were asked to provide, from their regular family doctor, confirmation of their health status and/or additional medical data in order to make a re-evaluation. RESULTS: The rate of rejection for a licence for medical reasons was 3% on the basis of the standard evaluation and 17% on the basis of the re-evaluation (p<0.001). CONCLUSION: This study shows that the random evaluation of physician assessments of applicants for a driver's licence increases the detection rate of medical problems that can affect fitness to drive. The alarming difference in the rate of rejection between the two assessments may reflect a lackadaisical attitude of medical professionals toward the licence assessment procedure and/or physician unawareness of the medical restrictions on fitness to drive. Results of this study suggest that this subject must be included in medical education programmes.

A survey of primary care physicians' perceptions of their patients' use of complementary medicine.

PURPOSE: To study the perceptions and attitudes of primary care physicians concerning their patients' use of complementary medicine. METHODS: A questionnaire was distributed to all 165 primary care physicians attending a routine continuing-medicine education program. Items included physicians' estimated rates of patient utilization of complementary medicine or herbal remedies and of patient reportage of such use; physicians' knowledge about side effects and interactions of herbal remedies; and frequency with which physicians questioned their patients on the use of complementary medicine and herbal remedies. RESULTS: The compliance rate was 90.0% (n=150). Sixty-eight percent of physicians estimated that up to 15% of their patients use complementary medicine; 58% always or often asked their patients about it; 50% estimated that 10% of patients report use of complementary medicine, and 60% estimated the same rate for herbal remedies; 51% believed that herbal remedies have no or only mild side effects; more than 70% claimed that they had little or no knowledge about what herbal remedies are; 24% never referred patients for complementary medicine, and 69% did so occasionally. Twenty-five percent had some training in complementary medicine, and 31% practiced some kind of complementary medicine. Most of the physicians believed that people turn to alternative methods when they are dissatisfied with conventional medicine. CONCLUSIONS: Physicians underestimate the rate of complementary medicine use by patients, suggesting that many patients do not report such use to their physician. Since alternative treatments are potentially harmful and may interact with conventional medications, physicians should be encouraged to communicate with patients about complementary medicine in general and herbal remedies in particular, and they should regularly include questions about their use when taking histories. They should also inform themselves about risks of alternative treatments particularly with herbal remedies, and have access to appropriate information systems.

Breast-feeding and smoking habits among Israeli women.

BACKGROUND: Many women stop smoking before or during pregnancy, or while breast-feeding (nursing). OBJECTIVES: To assess the relation between breast-feeding and smoking habits. METHODS: A survey was conducted among 920 women attending family health clinics (group 1) and a maternity department (group 2) on their breast-feeding and smoking habits. RESULTS: A total of 156 women (16.95%) smoked during pregnancy. A significant correlation was found between breast-feeding and not smoking after delivery (P = 0.009 in group 1, P = 0.03 in group 2). A higher tendency to nurse was found among women with an uneventful pregnancy, who vaginally delivered a singleton at term weighing 2,500-4000 g, and who received guidance on breast-feeding. CONCLUSION: Professional guidance in favor of breast-feeding is crucial to increase the rate of nursing. Encouraging breast-feeding will probably decrease the rate of cigarette smoking.

Cancer registration in the Middle East.

This project signals an advance in cancer registration in the Middle East region. While it is too early to declare a major breakthrough, significant strides have been made toward establishing a basis for reliable information on the cancer burden at a population level and future collaborative efforts in cancer epidemiologic research and prevention.

Influenza surveillance during winter 1997-1998 in Israel.

BACKGROUND: Each winter influenza activity is a major cause of morbidity and mortality both in Israel and worldwide. OBJECTIVES: To identify the influenza viruses active in Israel during the winter season and to assess the extent of influenza morbidity. METHODS: Information was collected on a population of 18,684 individuals enrolled in two community clinics in central Israel. It included the total number of visits for acute respiratory infection--including influenza and influenza-like illness (ARI/flu-like)--during a 20 week surveillance period (23 November 1997 to 27 March 1998) and the percent of influenza virus isolates in nasopharyngeal specimens from a sample of patients with ARI/flu-like collected on a weekly basis during the same period. RESULTS: A total of 5,947 visits for ARI/flu-like were recorded among 18,684 enrolled patients in two community clinics (18.1%). The progressive increase in the number of visits for ARI/flu-like reached a peak on week 2/98 with 597 visits and a rate of 31.95 visits per 1,000 population. After this, a decrease to the initial values was evident by week 12/98. Most affected patients were in the age groups 5-14 and 65 years and over, with a rate of 733.5 and 605.3 visits per 1,000 population, respectively. Influenza virus was isolated from 92 of the 426 nasopharyngeal specimens (21.6%). The most commonly detected strain was A/Sydney/5/97 (H3N2) like (77.2%). The peak rate of isolates was recorded at the beginning of January (01/98). CONCLUSIONS: A/Sydney/5/97 (H3N2) like-strain was the dominant influenza virus. Its presence did not prevent the simultaneous activity of influenza A/H1N1 virus. The dynamic of the clinical disease as expressed by the weekly visit rate for ARI/flu-like was similar to the temporal pattern of the virological findings. The extent of morbidity suggests moderate epidemic activity.

Methylphenidate use for attention deficit hyperactivity disorder in northern Israel--a controversial issue.

BACKGROUND: The prevalence of attention deficit hyperactivity disorder and its pharmacologic treatment have increased dramatically in the past decade in the United States and Britain. We examined the use of methylphenidate hydrochloride for the treatment of ADHD in children in northern Israel. METHODS: We evaluated all prescriptions for methylphenidate filled in 1999 for children aged 5-18 years residing in northern Israel who were insured by Clalit Health Services, a health maintenance organization that covers approximately 70% of the population. RESULTS: Methylphenidate was prescribed to 1.45% of the children in northern Israel in 1999, an increase of 20% in the overall prevalence of methylphenidate use since 1992. Eighty-two percent were boys. The rate of prescription varied widely by type of settlement, from 0.2% in Arab cities and towns to 5.7% in kibbutzim. Primary care physicians wrote 78% of all the prescriptions. CONCLUSIONS: The increase in methylphenidate use was much smaller in northern Israel than in most other developed regions and countries. More efforts at diagnosis and treatment of attention deficit disorders may need to be directed at Arab populations and those with inadequate medical services.

Behavior of patients with flu-like symptoms: consultation with physician versus self-treatment.

BACKGROUND: The reasons that patients consult the clinic physician for common minor symptoms are not clearly defined. For seasonal epidemic events such as flu-like symptoms this characterization is relevant. OBJECTIVES: To identify the factors that prompt patients to seek medical attention, and correlate patient behavior with different demographic and disease variables. METHODS: A random sample of 2,000 enrolled people aged 18-65 years and registered with eight primary care clinics located throughout Israel were asked to report whether they had had flu-like symptoms within the previous 3 months. Those who responded affirmatively (n = 346) were requested to complete an ad hoc questionnaire evaluating their treatment-seeking behavior. RESULTS: A total of 318 patients completed the questionnaire (92% response rate), of whom 271 (85%) consulted a physician and 47 (15%) did not. Those who sought medical assistance had more serious symptoms as perceived by them (cough, headache and arthralgia) (P < 0.05), and their main reason for visiting the doctor was "to rule out serious disease." Self-employed patients were more likely than salaried workers to visit the clinic to rule out serious disease (rather than to obtain a prescription or sick note or to reassure family). They also delayed longer before seeking treatment (P = 0.01). CONCLUSION: In our study the majority of individuals with flu symptoms tended to consult a physician, though there were significant variations in the reasons for doing so, based on a combination of sociodemographic variables. We believe these findings will help primary care physicians to characterize their practices and to program the expected demand of flu-like symptoms.

Evaluation of the approach of primary care physicians to the management of streptococcal pharyngotonsillitis. IPROS Network.

BACKGROUND: Streptococcal pharyngotonsillitis remains a common illness in children and can lead to serious complications if left untreated. OBJECTIVE: To evaluate the diagnostic and management approach of a sample of primary care physicians in the largest sick fund in Israel to streptococcal pharyngotonsillitis in children. METHODS: A questionnaire was mailed to all physicians who treat children and are employed by the General Health Services (Kupat Holim Klalit) in the Jerusalem District. The questionnaire included data on demographics, practice type and size, and availability of throat culture and rapid strep test; as well as a description of three hypothetical cases followed by questions relating to their diagnosis and treatment. RESULTS: Of the 188 eligible physicians, 118 (62.5%) responded, including 65 of 89 pediatricians (73%) and 53 of 99 family and general practitioners (53.5%). Fifty-six physicians (47.4%) had more than 18 years experience, and 82 (70%) completed specialization in Israel. Mean practice size was 950 patients. Fifty-three physicians (43%) worked in Kupat Holim community clinics, 25 (21%) worked independently in private clinics, and 40 (34%) did both. A total of 91 (77%) had access to laboratory facilities for daily throat culture. The time it took for the results to arrive was 48 to 72 hours. For the three clinical scenarios, 90% of the physicians accurately evaluated case A, a 1-year-old with viral pharyngotonsillitis, and 100 (85%) correctly diagnosed case C, a 7-year-old with streptococcal infection. As expected, opinions were divided on case B, a 3-year-old child with uncertain diagnosis. Accordingly, 75 (65.3%) physicians did not recommend treatment for case A, compared to 109 (92.5%) for case C. For case B, 22 (19%) said they would always treat, 43 (36%) would sometimes treat, and 35 (30%) would await the result of the throat culture. For 104 (88%) physicians the antibiotic of choice for case C was penicillin, while only 9 (7.5%) chose amoxicillin. However, the recommended dosage regimens varied from 250 to 500 mg per dose, and from two to four doses daily. For case C, 110 physicians (93%) chose a 10 day duration of treatment. CONCLUSIONS: The primary care physicians in the sample (pediatricians, general practitioners and family physicians) accurately diagnosed viral and streptococcal pharyngotonsillitis. However, there was a lack of uniformity regarding its management in general, and the dosage regimen for penicillin in particular.

Diabetes and ischemic heart disease among Yemenite immigrants in Israel.

BACKGROUND: The pattern of diabetes and ischemic heart disease among emigrants from pre-industrialized societies to more developed countries may be explained by both genetic and environmental factors. OBJECTIVES: To describe and interpret the pattern of diabetes and ischemic heart disease among Yemenite immigrants in Israel and their second-generation offspring. METHODS: Medical record charts of adult Yemenites were surveyed in a primary care health center, and the data were compared with prevalence rates derived from a non-Yemenite population. RESULTS: There was a marked excess of non-insulin dependent diabetes mellitus among Yemenite immigrants over 45 years of age, but not of hypertension or ischemic heart disease. Yemenites with diabetes were far less likely to develop ischemic heart disease than non-Yemenites with diabetes (odds ratio for non-Yemenites compared with Yemenites, 3.5; confidence interval 1.54 < OR < 7.77). CONCLUSIONS: There was less of an association between diabetes and ischemic heart disease among Yemenites. This finding requires further investigation of the relative roles of genetic and environmental factors.

Death and injury from motor vehicle crashes in Colombia.

We report data on the distribution and determinants of road deaths and injuries for all victims in Colombia, with the aim of defining targets and priorities for highway death prevention in that country and other rapidly urbanizing nations. Using information from Colombia's Fund for the Prevention of Road Injury and the national death registry, we studied data on deaths and injuries from 1991 to 1995 for the nation as a whole and for the country's two largest cities, Santa Fe de Bogotá and Medellín. Deaths and injuries are rising in the nation as a whole. Of the deaths, 75% occur in urban areas, and 80% are in males. Pedestrians aged 15-34 are a peak subgroup. Thirty-four percent of deaths are attributable to speeding and/or alcohol consumption. Death tolls are highest at night and on weekends. Specific priority targets for intervention are indicated by the fact that 75% of road deaths in Colombia occur in urban areas and that 80% of all victims are males.

Knowledge and attitudes of primary care physicians regarding battered women. Comparison between specialists in family medicine and GPs.

BACKGROUND: Domestic violence is a widespread public health problem and an important part of primary care practice. OBJECTIVE: To evaluate the approach of primary care physicians (family physicians and GPs) to the care of battered women. METHODS: A self-report questionnaire containing items about experience, knowledge and attitudes regarding the care of battered women was mailed to a random sample of 300 primary care physicians employed by the two major health management organizations in Israel. The population included family physicians, who have 4 years of residency training in primary care, and GPs, who do not undergo specialization after completing their medical studies. RESULTS: A total of 236 physicians (130 family physicians and 106 GPs) responded. In general, the physicians had had very little exposure to the problem and estimated its prevalence in the community as less than half that indicated in the medical literature. Compared with the GPs, however, the family physicians reported more exposure to the subject (P < 0.001) and had better knowledge of its prevalence and risk factors (P < 0.001). They also showed a greater tendency to view the problem as universal (P < 0.05) and as part of their professional responsibilities. However, both groups tended not to include the care of battered women with no physical injury within their professional duties. CONCLUSIONS: Physicians should be made more aware of the problem of battered women within the context of their routine professional practice and of the importance of keeping abreast of the subject. Educators should place more emphasis on imparting knowledge and skills in the management of battered women, especially for GPs.

Patient adherence to family practitioners' recommendations for breast cancer screening: a historical cohort study.

BACKGROUND: Breast cancer is the most prevalent malignancy among women in Israel, and routine screening is recommended for early detection. In 1997, a health management organization primary care centre in rural Israel established a 1-year programme wherein family physicians were encouraged to remind their patients to undergo breast cancer examinations. This study evaluates the impact of the physicians' intervention on patient compliance. METHODS: Family practitioners from two practices were requested to discuss the importance of early breast cancer detection with all eligible patients who visited the clinic for any reason and to assist them in scheduling an appointment for screening. The files of the patients who received the recommendation were stamped accordingly. On completion of the programme, the physicians' files were audited, and the potential candidates for breast cancer screening were divided into two groups: those who had received the intervention (n = 251) and those who had not (n = 187); results were also compared with those of a third group of patients who had gone for an examination on their own initiative (n = 100) prior to the study (i.e. did not require intervention). A random sample of half the patients also completed an ad hoc questionnaire covering sociodemographic variables and the impact of the doctors' intervention on their behaviour. RESULTS: Patients in the intervention group showed a significantly greater change in behaviour regarding breast cancer screening than the controls (32% versus 13%, P = 0.001). This change was manifested particularly in the group of women aged 50-74 years who received the recommendation for mammography to be performed (according to the guidelines). CONCLUSION: Although this is a study in only two practices, the results suggest that primary care physicians can significantly alter the behaviour of their patients regarding regular breast examinations. The use of a special reminder can also help the individual doctor to ensure that each patient has been properly instructed.

Primary care physicians' attitudes to battered women and feelings of self-competence regarding their 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.
