During craniotomy, the patient's cooperation is needed during procedures in which continuous neurological examination and mapping of crucial regions close to the area to be resected area are required. We report our experience in 9 patients who underwent such procedures under intravenous propofol as the main sedating agent. This short-acting hypnotic was administered prior to and during the painful stages of the procedure. Patients were fully asleep when the skull was opened and the dural flap raised or excised. During the rest of the operation patients were lightly sedated but remained responsive and cooperative. This enabled precise intra-operative mapping of the brain and surgery-related neurological deficits were avoided. Respiratory depression or hemodynamic compromise were not encountered. All patients were comfortable during the operation and there were no additional neurological deficits after operation. We believe that propofol should be the main sedating agent used for these procedures.

Gentamycin Distribution Volume in a Mechanically Ventilated Patient

Mechanical ventilation (MV) of more than 32 hours may alter the gentamycin pharmacokinetic profile by increasing its volume of distribution (VD). As a result, the standard garamycin dosage regime has to be adjusted in order to obtain an adequate peak serum concentration, which is well correlated with the efficacy of garamycin therapy. Garamycin is a water- soluble drug with negligible binding to plasma albumin, so its VD approximates the volume of extra-cellular fluid, which may be expanded by MV. MV-related fluid retention is mediated via various homeostatic compensatory systems. They are activated to combat the decrease in cardiac output and central blood volume caused by MV, due to the increase in airway and intrathoracic pressure. These phenomena are more prominent during prolonged ventilation, PEEP or C-PAP ventilation, and in previously hypovolemic patients. Patients requiring MV for more than 32 hours had an average garamycin VD of 0.36 L/Kg compared with the mean VD of 0.25 L/Kg in normal adults. In the patient presented, a similar change in garamycin VD was seen, while conventional doses given during MV failed to reach suitable clinical peak levels.

Bloodstream infections (BSI) are 7-fold more common in patients admitted to the intensive care unit (ICU) rather than to other hospital wards. The epidemiology of BSI in critically ill patients in Israel has not been systematically addressed. We examined the annual trends in BSI in patients in a general ICU of evolving patterns of antimicrobial resistance and associated mortality rates for the years 1994-1996. The presence of the systemic inflammatory response syndrome (SIRS) when the first positive blood cultures are taken was a prerequisite for its definition as clinically significant. The unit site, staff, practice guidelines, and type of patient were unchanged during the study period. Blood cultures were positive in 220.7-332.0 patients per 1000 ICU admissions, 18-22-fold more common than in regular ward patients. SIRS was a universal finding in these ICU patients. There was multi-drug resistance for the majority of species cultured, reaching 100% in some cases. Crude hospital mortality of ICU patients, with and without positive blood cultures, was 31-54% and 5-14%, respectively. The introduction of a new blood culture system (Bactec 9240) in 1996 was associated with a 61% increase in the rate of patients with positive blood cultures, accounted for mostly by increased isolation of coagulase-negative staphylococci. However the mortality rate for the latter decreased by 59%, suggesting the possibility of a selective increase in detection of contaminated cultures. Although highly prevalent in the study population and generally defining a patient group with high mortality risk, the specificity of SIRS-associated positive blood cultures may be species and culture-system dependent. These findings re-emphasize the need for both improved control measures for the epidemic proportions of BSI and multi-drug antimicresistance, as well as more specific indicators of the clinicaof positive blood cultures in critically ill patients.

Patients' opinions of the role of the primary care physician were studied. The study population consisted of Hebrew-speaking members of the Clalit Sick Fund, aged 18+, who visited primary care and specialty clinics. Interviews took place during January-March 1995 in the Emek and Jerusalem, and during August-October 1995 in Beer Sheba. A total of 2,734 interviews were conducted, and the response rate was 88%. 64% of the respondents preferred the primary care physician as the first address for most problems occurring during the day. Multivariate analysis revealed that the variables predicting this preference were: being over age 45, having completed less than 12 years of schooling, being satisfied with the physician, and when a child's illness was involved. Whether the physician was a specialist had only a marginal effect. The findings also show that among those who did go directly to a specialist for the current visit, 49% would still prefer the primary care physician to be the first address for most problems. However, half of the respondents initiated the current visit to the specialty clinic themselves. The findings also showed that a preference for the primary care physician to be the first address had an independent and statistically significant effect on the following aspects of service consumption: taking the initiative to go to a specialist, the intention to return to the primary care physician or to the specialist for continuing care, and the patient's belief that referral to a specialist was needed. The findings of the study may be of assistance to policy-makers on the national level and to sick funds in planning the role of the primary care physician, so that it corresponds, on the one hand, to the needs of the sick funds and the economic constraints in the health system, and on the other, to the preferences of the patient.

We studied the social and cultural frameworks that impact on breast cancer patients in the medical system. The subjects were 98 Jewish women who had undergone mastectomy or lumpectomy for cancer 6 months to 3 years prior to the interview. They emanated from a variety of socioeconomic and ethnic backgrounds, and reflected the age range of women with breast cancer in the general Jewish population of Israel. Patients were asked about each stage of the medical process they had experienced: diagnosis, surgery, oncological care, and follow-up care. The interview revealed a general perception of having received insufficient information regarding their medical condition and treatment. The problem tended to be most severe during the diagnostic stage, when women had not yet been officially included as patients within the system. The problem was relatively severe during follow-up care, when they often did not have an address for their questions. Few women received a schedule of follow-up care that allowed them to carry on with the many necessary tests in an orderly and comprehensive manner. Most important, systematic absence of informed consent also characterized the decision-making process regarding surgery and oncological treatment. Few women felt they had been informed about treatment options, side-effects, or long-term implications of the treatment offered. We found no indication of inequitable medical treatment that would suggest a manifest pattern of discrimination, but we did find some social variables related to a feeling of insufficient personal care and information. In particular, older women said they received less attention, support, and information from the medical staff relative to the younger women.

Forearm bone fractures are commonly the result of falling on the outstretched hand or of direct injury. The preferred treatment is debated. The possible modalities are: application of a cast, often necessitating repeated manipulations; open reposition and fixation by plates and screws; or closed manipulation and closed intramedullary nailing. We present our favorable results in treating these fractures in young patients by closed intramedullary nailing, and compare them with the unfavorable results of this method in mature adults.

Six Cases of Acute Rheumatic Fever in One Year

George Habib, Ramiz Abu-Ahmad

Rheumatology Clinic and Dept. of Medicine, Nazareth Hospital; and Medical Dept. B, Carmel Medical Center, Haifa

During 1995, 6 cases of acute rheumatic fever were diagnosed here. Taking into account differences in total admissions, this appears to represent an increase over 1994. Most of the cases were males, with average age at diagnosis 19.5 years. All were of low socioeconomic status. 50% had cardiac involvement, and 1 needed treatment with corticosteroids. Most had pharyngeal symptoms prior to the acute attack, and 1 patient had 2 prior episodes of rheumatic fever. A thorough epidemiological study should be done in the Nazareth area to assess the real incidence of acute rheumatic fever, and to determine whether there is a true increase in incidence.

Bromocriptine for Refractory Rheumatoid Arthritis

Reuven Mader

Rheumatic Disease Unit, HaEmek Medical Center, Afula

In recent years prolactin (PRL) has emerged as an important immunomodulator in various autoimmune disorders. Bromocriptine (BRC) is a dopamine agonist that suppresses secretion of PRL. Good clinical response to BRC has been reported in patients with psoriatic arthritis, Reiter's syndrome, and systemic lupus erythematosus. 5 mg of BRC at bedtime were given to 5 patients (aged 35-50) with refractory rheumatic arthritis (RA) who had failed to respond to previous treatment with at least 2 disease-modifying antirheumatic drugs. Patients were assessed at 4-6 week intervals for 6 months. 3 showed more than 25% improvement in the number of tender and swollen joints at 12 weeks of treatment. However, in only 2 of them was improvement maintained till the end of the 6 months. There were no changes in other measures of disease activity. 1 patient dropped out of the study due to acute exacerbation of her disease 4 weeks after initiation of BRC and required intra-articular injections of corticosteroid. The remaining patient did not show any significant clinical changes. No correlation was found between serum PRL levels and disease activity over time. It is suggested that some patients with refractory RA might improve with BRC. Its use in larger doses in larger groups of patients may help elucidate its role in the treatment of RA.

112 patients with localized prostate cancer, clinical stage A2-C, were treated by definitive radiotherapy between 1982-1988. Radiation volume encompassed the prostate, seminal vesicles and pelvic lymph nodes. The 10-year actuarial survival figures were: overall 51%; stage A2 87%; stage B 50%; stage C 36%; well differential tumors 67%; moderately differentiated 50%; poorly differentiated 32%; patients with local tumor control 55%; and patients with minimal local control 36%. It is concluded that external beam irradiation is effective in localized prostatic cancer. Stage and grade are prognosticators of survival.

Many studies have tried to explain why professionals experience difficulty when dealing with, and in treating efficiently situations connected with death. We studied levels of personal fear among physicians in general hospitals and addressed 2 questions: Does exposure to death on professional and personal levels, affect the level of the fear of personal death which physicians experience? Is there a relationship between personality variables, represented by the repression-sensitization dimension, and level of fear of personal death? A sample of 233 physicians from 22 general hospitals who specialized in oncology, internal medicine, surgery, psychiatry or pediatrics was studied. Each answered 4 questionnaires with regard to demographic information, fear of personal death, level of repression-sensitization and exposure to the death of relatives and significant others. There were no differences in level of fear of personal death of physicians according to specialization, but those who had been exposed to death on the personal level, feared less their own death. With respect to the personality variable, tendency to sensitization, it was found that those who were sensitized exhibited a higher level of the fear of their own death compared to those who were repressive. Of the various demographic variables examined (sex, level of religiouobservance, age, number of children, health, professional experience) it was found that those: with many years of professional experience, who were relatively older, who were nonobservant religiously and who were in good health, had lower levels of personal fear of death; gender was not a factor.

In a study examining the relationship between patient participation in clinical decision making and levels of anxiety, patients were offered a choice of treatment for ureteral calculus. 42 received information about 2 treatment options, ultrasound fragmentation of the stone through a ureteroscope and extracorporeal shock wave lithotripsy (ESWL), and were asked to choose the method that they preferred. 54 received treatment decided on by the physician without their participation in the decision making process. Anxiety was measured before meeting with the physician, immediately after the meeting and on hospitalization for treatment. The contribution of the patient's perception of participation in the decision- making process and level of education was also examined. There was a decrease in level of anxiety after meeting with the physician only among those who did not actually participate in the decision-making process (p<0.05). There was no change in the level of anxiety among those offered choice of treatment. However, a decrease in anxiety was evident among patients who perceived that they had received information about their illness and its treatment (p<0.01). This was not the case for patients who perceived themselves as participants in decision making unless they had a relatively high-level of education (p=0.05).

To study the effect of stroke on the quality of life in younger adults, 199 patients 17-49 years of age who had sustained a first stroke between 1.11.92 and 31.10.93 were followed up. They were interviewed by telephone at 3, 6, 12 and 24 months after the event. 2 died during the first year of follow-up, and 8 had recurrent strokes. After 2 years, 8 additional patients had died and 4 had sustained recurrent events. Gradual improvement was reported within all age groups and in all areas. During the 3-6 months period, a mean of 4% improvement occurred in functional capability, 15% in social and recreational activity and 8% in return-to-work. The 6-12 month period showed an increase of 3% in improvement in mean functional capability, 10% in social and recreational activity and 2% in return-to-work. 1 year after the stroke 27% remained with moderate to severe disability, but over 86% were functionally independent in their daily living activities. There were no significant changes during the second year of follow-up in these statistics. 67% of those employed prior to their stroke returned to work and approximately 70% reported a return to prestroke social and recreational activity. These results demonstrate that the relatively high recovery rate and functional improvement during a year of follow-up were not accompanied by similar rates of improvement in emplyment and in social integration. They indicate the need for increased emphasis on long-term psychosocial rehabilitation services within the community.

Q Fever Endocarditis and Bicuspid Aortic Valve

Q fever is caused by the rickettsia Coxiella burnetti, an obligate intracellular bacterium acquired by inhalation of infected dust from subclinically infected animals. Q fever may be acute or chronic; the chronic form mostly presents as endocarditis. Immunocompromised states and underlying heart disease are the most important risk factors. Usually the symptoms of Q fever endocarditis are nonspecific and diagnosis is often established very late. New criteria for diagnosis include a single blood culture positive for Coxiella burnetti, positive Q fever serology and characteristic echocardiographic studies. We describe a 49-year-old man with bicuspid aortic valve admitted with fever, weight loss and a new heart murmur. The diagnosis of Q fever endocarditis was established by positive Q fever serology, and an echocardiogram showing vegetations and valvular dysfunction. This case suggests that Q fever endocarditis should be considered in patients with "sterile" endocarditis.

The appearance of focal pulmonary lesions in a patient with a nonpulmonary malignancy is worrisome. Apart from metastasis, the differential diagnosis includes benign conditions such as infectious and granulomatous diseases, enlarged lymph nodes, atelectasis, radiation pneumonitis, and bronchiolitis obliterans with organizing pneumonia (BOOP). CT-guided needle biopsy is not always diagnostic and may not be feasible in very small lesions. Since open lung biopsy is associated with considerable morbidity, many physicians tend to postpone tissue diagnosis for a few weeks and perform a biopsy only if repeat chest CT scans show increase in size or number of the lesions. This approach may lead to undesirable delay of appropriate treatment. We report video-assisted thoracoscopic lung biopsy in 7 patients with nonpulmonary malignancy who developed lung lesions following chemotherapy and/or radiation therapy. Histological examination proved metastatic lesions in only 2. There were no operative complications and recovery was rapid and smooth in all patients. Thoracoscopic lung biopsy is an effective, minimally invasive diagnostic tool that obviates the need for thoracotomy in these patients.

Should Physical Restraints be used in an Acute Geriatric Ward?

Svetlana Barazovski, Arnold Rosin

Geriatric Dept., Shaare Zedek Medical Center, Jerusalem

A prospective study was carried out in an acute geriatric ward to determine the incidence of the use of physical restraints, the reasons for using them and the consequences. Over a period of 8 months an independent observer documented all cases in which a restraint was used and followed them until it was removed. A questionnaire was submitted to the nurses as to why they applied the restraints. 16% of patients had some form of restraint applied, in 2/3 of them for up to half of their stay in the ward. In over 90% of those restrained, functional (Barthel) and cognitive (mini-mental) scores were between 0-5. In unrestrained patients, the functional score was 0-5 in 79% and the cognitive score 0-5 in 72%. The main reason for applying restraints, usually sheets or body binders, was to prevent the patient from falling out of, or slipping from chairs, rather than to stop them from rising out of them. Other important reasons, which overlapped, were to prevent the patient from interfering with nasogastric tubes, catheters, and IV cannulas, each in 1/3 of the group. Restraints were discarded when deterioration did not allow the patient to sit out of bed, to decrease agitation, to allow enteral or parenteral treatment, and in 12%, when there was supervision by the family. Of 33 families interviewed, none opposed application of restraints, and most left the decision to the responsible ward staff. We conclude that restraints cannot be avoided in some acutely ill, old patients with severe physical and mental dysfunction. However, ways should be sought to minimize their use, as recommended in the literature, by demanding from the staff a specific reason, signed agreement of a physician, close follow-up, and favorable environmental conditions such as suitable chairs, occupational activity, and staff cooperation in removing the restraints.
