Background: The chronic progressive course of peripheral arterial occlusive disease with its limb-threatening and life-threatening potential is associated with physical, psychological and social distress for elderly patients and their families.

Objective: To evaluate the influence of infra-inguinal bypass surgery for limb salvage, and social support, on quality of life in elderly patients (over 60 years old).

Methods: Sixty patients aged 60 years and above diagnosed with limb-threatening ischemia were evaluated using the SF-36 generic questionnaire for quality of life, and the MOS-SS questionnaire for social support. Thirty patients (group I) were evaluated in the hospital prior to reconstructive surgery and 30 postoperative patients (group II) were evaluated at home at least 6 months after infra-inguinal bypass operations. Both groups were comparable in terms of age, gender, prevalence of ischemic heart disease, diabetes, and other atherosclerosis risk factors.

Results: All quality of life parameters were higher among patients who underwent limb salvage surgery (group II) as compared to preoperative patients (group I), yet the obtained values were lower than those in the general population. Patients in the surgical intervention group had higher levels of function, lower pain levels, and higher emotional and social well-being and, in addition, were spared limb amputation. The findings also indicate that the social support dimensions (emotional support, receipt of information, affection and positive social interaction), as measured in terms of perceived availability, do not operate as one entity. Different types of social support were more beneficial along different stages of the disease.

Conclusion: Peripheral arterial occlusive disease causes severe impairment of the quality of life in elderly patients. Arterial reconstructive surgery improves the quality of life though it still remains low compared to the general population. Social support is beneficial in the treatment of these patients, and the social worker in the vascular surgery department has a key role in identifying the various needs of the patients along the path of their chronic illness.
 

Background: Risk factors for injurious falls among elderly people differ from those for falls in general. The characteristics of falls play an important role in determining the risk of hip fracture.

Objective: To investigate the risk factors associated with the fall characteristics known to be associated with the majority of hip fractures, e.g., a lateral fall and a subsequent impact on the greater trochanter.

Methods: In this 6 month prospective observational case-control study 101 individuals aged 65 years and over hospitalized following a hip fracture were interviewed 7–14 days after the accident. Data were also obtained from medical records, focusing on known predisposing and situational risk factors for the fall. We compared the risk factors between two groups: patients who suffered a lateral fall and subsequent impact on the greater trochanter of the femur, and patients who suffered other types of falls.

Results: Only 51.5% of the hip fracture patients reported that they had fallen directly to the side. Apart from age, there were no significant differences between the groups in other factors studied. When considering both fall direction and the area that took the main impact, we found that the majority of patients (85%) reported having fallen onto the posterolateral aspect and/or a fall with an impact on the greater trochanter.

Conclusion: Our findings did not show differences (except for age) in the factors studied between the groups. This study suggests that both fall direction and the area that takes the main impact should be considered in the characteristics of falls that might cause a hip fracture. Characteristics associated with greatest fracture risk include a fall onto the posterolateral aspect and/or a fall with an impact on the greater trochanter. More studies are needed to evaluate potential risk factors associated with this type of injury.

Background: Training in geriatric psychiatry constitutes a fundamental element toward further development of this relatively new branch of medicine. However, it varies both in quantity and quality among different countries, healthcare providers and medical schools.

Objectives: To describe the demographic and professional characteristics of participants in postgraduate diploma courses in geriatric psychiatry, and the perceived contribution of the courses; and to compare these variables among the participants in 1 year and 3 year courses, and between psychiatrists and non-psychiatrists.

Methods: A retrospective self-administered questionnaire was mailed to the 153 physicians who participated in the two courses. The 60 questionnaires completed and returned were analyzed.

Results: Participants in the courses constituted a heterogenous group in terms of demographic and professional characteristics, with no differences between 1 year and 3 year course participants, or between psychiatrists vs. non-psychiatrists (with the exception of more involvement of non-psychiatrists and 1 year course participants in old-age homes). Most responders indicated both the theoretical and practical benefits and application to daily practice of the material learned. Similarly, most responders indicated that after the courses they definitely used general assessment scales to a much greater extent, particularly cognitive scales, as well as operational diagnostic criteria for dementia. Participants in the 3 year course reported more significant use of assessment scales compared with 1 year participants, and 3 year participants and psychiatrists used the cognitive scales more often. There were no other significant differences between 1 year and 3 year participants and between psychiatrists’ and non-psychiatrists’ reports regarding general and more specific contributions of the courses.

Conclusion: Postgraduate diploma courses in geriatric psychiatry seem to have a favorable effect on participants, irrespective of course duration or specialty. However, course duration positively influenced the implementation of assessment scales in general, and cognitive scales in particular. A prospective comparative study on this subject is warranted, with stricter definitions of participants’ pre-course and post-course background, attitudes, knowledge and benefits.
 

Background: Little information is available on the clinical practice and implementation of guidelines in treating acute myocardial infarction patients in Israel.

Objective: To assess patient characteristics, hospital course, management, and 30 day clinical outcome of all AMI[1] patients hospitalized in Israel during a 2 month period in 2000.

Method: We conducted a prospective 2 month survey of consecutive AMI patients admitted to 82 of 96 internal medicine departments and all 26 cardiac departments operating in Israel in 2000. Data were collected uniformly by means of a hospital and 30 day follow-up form.

Results: During the survey 1,683 consecutive patients with a discharge diagnosis of AMI were included. Their mean age was 66 years; 73% were male. The electrocardiographic pattern on admission revealed ST elevation, non-ST elevation and an undetermined ECG[2] in 63%, 34% and 4% of patients respectively. Aspirin and heparin were given to 95% of patients. Beta-blockers and angiotensin-converting enzyme inhibitors were given to 76% and 65% of patients respectively. Among hospital survivors, 45% received lipid-lowering drugs. Thrombolytic therapy was administered in 28% of patients, coronary angiography was used in 45%, and 7% of patients underwent primary percutaneous coronary intervention. The 7 and 30 day mortality rates were 7% and 11% respectively.

Conclusions: This nationwide survey shows that one-third of the AMI patients in Israel are elderly (≥ 75 years). The survey suggests that clinical guidelines for the management of patients with AMI are partially implemented in the community. Data from large surveys representing the "real world" practice are of utmost importance for the evaluation of clinical guidelines, research and educational purposes.

Background: Although the preferred management of a patient presenting with an acute myocardial infarction is in a coronary care unit, data based on discharge diagnoses in Israel indicate that many of these patients are treated outside such units.

Objectives: To compare the demographic and clinical characteristics, treatment and mortality of AMI[1] patients treated inside and outside a CCU[2].

Methods: We compiled a registry of all patients admitted to three general hospitals in Haifa, Israel during January, March, May, July, September and November 1996.

Results: The non-CCU admission rate was 22%. CCU patients were younger (61.6 vs. 65.5 years), less likely to report a past AMI (18% vs. 34%), and arrived earlier at the emergency room. Non-CCU patients were more likely to present with severe heart failure (30 vs. 11%). Non-CCU patients received less aspirin (81 vs. 95%) and beta-blockers (62 vs. 80%). Upon discharge, these patients were less frequently prescribed beta-blockers and cardiac rehabilitation programs. CCU-treated patients had lower unadjusted mortality rates at both 30 days (odds ratio=0.35) and in the long term (hazards ratio=0.57). These ratios were attenuated after controlling for gender, age, type of AMI, and degree of heart failure (OR[3]=0.91 and HR[4]=0.78, respectively).

Conclusions: A relatively high proportion of AMI patients were treated outside a CCU, with older and sicker patients being denied admission to a CCU. The process of evidence-based care by cardiologists was preferable to that of internists both during the hospital stay and at discharge. In Israel a significant proportion of all AMI admissions are initially treated outside a CCU. Emphasis on increasing awareness in internal medicine departments to evidence-based care of AMI is indicated.

Background: Puncture wounds in the feet of children present a clinical dilemma.

Objectives: To evaluate our approach, we reviewed the charts and all available images of 80 children admitted to our institution because of plantar punctures from 1988 to 1999.

Methods: The charts of 80 children were reviewed retrospectively.

Results: Three groups of patients were found: 59 with superficial cellulitis, 11 with retained foreign bodies, and 10 with osteomyelitis and/or septic arthritis. There was a significant presentation delay in patients from the second and third groups. Most common organisms were Staphylococcus aureus or Group A Streptococcus. Of the 80 children, 34 were treated surgically and 46 were treated with antibiotic therapy alone. All patients with osteomyelitis and septic arthritis were re-examined; at follow-up, all but one were asymptomatic apart from residual radiologic sequelae in four.

Conclusions: Patients with an established infection 24–36 hours after a plantar puncture should be admitted to hospital for parenteral antibiotic therapy. Delayed presentation is a significant marker for deep-seated infection. Further infection or relapse after initial improvement suggests the presence of osteomyelitis or a retained foreign body. A bone scan is advisable in all patients with suspected osteomyelitis: a positive bone scan necessitates aggressive early debridement combined with appropriate antibiotics; while negative bone scan, X-ray and exploration suggest that the infection is due to a foreign body, which can be detected by computed tomography.
 

Background: The mainstay of therapy for acute cholecystitis is cholecystectomy, which has a mortality of 14–30% in high risk patients. An alternative approach in patients suffering from acute cholecystitis with contraindications to emergency surgery is percutaneous cholecystostomy.

Objective: To evaluate the efficacy and safety of percutaneous cholecystostomy as the initial treatment of acute cholecystitis in high risk patients.

Methods: Eighty consecutive patients (42 men, 38 women) underwent ultrasound-guided percutaneous cholecystostomy over a 5 year period. Sixty-five patients suffered from acute calculous cholecystitis, 4 patients had acalculous cholecystitis, and 11 patients had sepsis of unknown origin.

Results: Sixty-eight patients improved after the percutaneous gallbladder drainage, 10 patients died from co-morbid disease and 2 patients died from biliary peritonitis. During a 1 year follow-up, 32 of the patients underwent interval cholecystectomy, 4 additional patients died from a co-morbid disease, 18 patients did not suffer from any gallbladder symptoms, and 14 were lost to follow-up.

Conclusions: Percutaneous cholecystostomy is an effective contribution to the treatment of acute cholecystitis in high risk patients.

Background: Intestinal malrotation is usually observed in the neonatal period with signs of acute high intestinal obstruction due to midgut volvulus. However, malrotation presenting beyond the neonatal period and well into adult life is associated with a variety of atypical and frequently non-specific gastrointestinal symptoms that may often cause prolonged delay in diagnosis and appropriate treatment.

Objectives: To emphasize the difficulty in predicting the risk of midgut volvulus based on age or symptoms, and to recommend surgery in all patients found to have intestinal malrotation even if they are considered asymptomatic.

Methods: We reviewed 41 patients with malrotation treated over a period of 24 years at the Soroka University Medical Center.

Results: In our series, 27 patients (66%) had acute midgut volvulus while 14 (34%) had malrotation found during investigation of various long-term gastrointestinal non-specific symptoms. Two patients died of total parenteral nutrition-related sepsis following extensive resection of small bowel. A total of 28 patients was available for long-term follow-up and are asymptomatic.

Conclusions: We recommend elective laparotomy and Ladd procedure in all patients found to have intestinal malrotation. This will prevent the catastrophic results of midgut volvulus and a variety of gastrointestinal symptoms wrongly attributed to other conditions in the span of a lifetime.

Background: Current clinical guidelines restrict catheterization laboratory activity without on-site surgical backup. Recent improvements in technical equipment and pharmacologic adjunctive therapy increase the safety margins of diagnostic and therapeutic cardiac catheterization.

Objective: To analyze the reasons for urgent cardiac surgery and mortality in the different phases of our laboratory’s activity in the last 11 years, and examine the impact of the new interventional and therapeutic modalities on the current need for on-site cardiac surgical backup.

Methods: We retrospectively reviewed the mortality and need for urgent cardiac surgery (up to 12 hours post-catheterization) through five phases of our laboratory’s activity: a) diagnostic (years 1989–2000), b) valvuloplasties and other non-coronary interventions (1990–2000), c) percutaneous-only balloon angioplasty (1992–1994), d) coronary stenting (1994–2000), and e) use of IIb/IIIa antagonists and thienopiridine drugs (1996–2000).

Results: Forty-eight patients (0.45%) required urgent cardiac surgery during phase 1, of whom 40 (83%) had acute coronary syndromes with left main coronary artery stenosis or the equivalent, and 8 (17%) had mechanical complications of acute myocardial infarction. Two patients died (0.02%) during diagnostic procedures. In phase 2, eight patients (2.9%) were referred for urgent cardiac surgery due to either cardiac tamponade or severe mitral regurgitation, and two patients (0.7%) died. The combined need for urgent surgery and mortality was significantly lower in phase 4 plus 5 as compared to phase 3 (3% vs. 0.85%, P = 0.006).

Conclusion: In the current era using coronary stents and potent antithrombotic drugs, after gaining experience and crossing the learning curve limits, complex cardiac therapeutic interventions can safely be performed without on-site surgical backup.
 

Background: Fractures of the stemum may be associated with major injuries to thoracic organs, with serious consequences.

Objective: To assess the hospital course of patients diagnosed with isolated sternal fracture.

Methods: We reviewed 55 medical records of patients who were admitted with isolated sternal fracture to the emergency department during the period from January 1990 through August 1999.

Results: Fifty-one patients were involved in motor vehicle accidents, and the remainder sustained the injury as a result of a fall. Lateral chest X-ray upon admission was diagnostic in the majority of these patients (n=53). Electrocardiography (n=52) was abnormal in four patients – old myocardial infarction (n=1), non-specific ST-T changes (n=3). Cardiac enzymes (creatine-kinase-MB, n=42) were pathologically elevated in five patients. Echocardiography, performed in patients with ECG[1] abnormalities and/or elevated myocardial enzymes (n=7), was normal in these patients as well as in another 18 patients. There were no intensive care unit admissions or arrhythmias during the hospital stay, which ranged from 6 hours to 6 days (mean 2.3 ± 1.3 days, median 2 days).

Conclusion: Our findings support the view that patients with isolated sternal fracture, who have no abnormality in ECG and cardiac enzymes during the early hours after injury, are expected to have a benign course and can be discharged home from the emergency room within the first 24 hours.
