Background: Due to increasing antimicrobial resistance there has been renewed interest in old drugs that have fallen into disuse because of toxic side effects.

Objectives: To evaluate the susceptibility profile, in our hospital, of Enterobacteriaceae and Streptococcus pneumoniae isolates to chloramphenicol and to compare them with the susceptibility to amoxicillin-clavulanate.

Methods: All isolates of Enterobacteriaceae and S. pneumoniae recovered in our lab during a one year period were tested for susceptibility to chloramphenicol and amoxicillin-clavulanate or penicillin, respectively.

Results: Of 413 Enterobacteriaceae isolates, 182 (44.1%) were resistant to amoxicillin-clavulanate, but only 76 (18.4%) were resistant to chloramphenicol. Of 189 isolates of S. pneumoniae, 4 (2.1%) were highly resistant to penicillin and 73 (38.8%) were partially resistant, while only 2 (1.1%) were resistant to chloramphenicol. None of the 24 S. pneumoniae isolates causing invasive diseases exhibited resistance to chloramphenicol.

Conclusions: In an era of increasing resistance to many antibiotic preparations, chloramphenicol might have a role in the treatment of intraabdominal and respiratory tract infections.

Background: While the burden of rotavirus infection with regard to hospitalizations has been extensively investigated, there are sparse data regarding the impact and the cost of this infection on the ambulatory part of the health system in Israel.

Objectives: To investigate the burden of rotavirus infection on the ambulatory system in Israel.

Methods: Infants younger than 3 years old examined for acute gastrointestinal symptoms in four pediatric clinics had their stool tested for rotavirus. The parents were contacted 7–10 days later and questioned about the symptoms of illness, medications given, use of diapers, consumption of formula, and any loss of parents' workdays.

Results: Rotavirus was detected in 71 of the 145 stool samples tested (49%). A total of 51 parents responded to the telephonic survey. Patients' mean age was 15.4 months. Three patients were hospitalized due to the illness. The mean duration of fever was 1.7 days. Infants with rotavirus gastroenteritis had on average 2.25 days of vomiting and 7.5 days of diarrhea. The average number of workdays lost was 2.65 days per RVGE[1] case. The cost of the average case of RVGE in Israel is 257 euros; 69.64% of this cost (179 euros) is due to parental work loss.

Conclusions: Our results indicate that the economic impact of the ambulatory cases in Israel is quite significant.

Background: Identification of pathogens and their susceptibility to antimicrobials is mandatory for successful empiric antibiotic treatment.

Objectives: To compare the clinical characteristics of patients with bacteremia, as well as the bacterial distribution and antimicrobial susceptibility in community, hospital and long-term care facilities during two periods (2001–2002 and 2005–2006).

Methods: The study was conducted at the HaEmek Medical Center, a community 500-bed teaching hospital in northern Israel serving a population of ~500,000 inhabitants. All episodes of bacteremia (n=1546) during two 2 year periods (2001–2 and 2005–6) were prospectively recorded, evaluated and compared (755 in 2001–2 and 791 in 2005–6).

Results: In both periods the urinary tract was the main port of entry in community and long-term care facility bacteremia, while the urinary tract – primary and catheter-related – were similar in frequency as sources of hospital bacteremia. Escherichia coli was the most frequent pathogen isolate. No significant changes in the frequency of methicillin-resistant Staphylococcus aureus and extended-spectrum beta-lactamase-producing bacteria were seen between the two 2 year periods (2001–2 and 2005–6). The susceptibility of non-ESBL[1]-producing E. coli decreased for some antibiotics while non-ESBL-producing Klebsiella pneumoniae susceptibility profile improved in the same period. A non-statistically significant trend of increased resistance in gram-negative isolates to quinolones, piperacillin and piperacillin-tazobactam was observed, but most isolates still remained highly susceptible to carbapenems. There was a small increase in mortality rate in hospital bacteremia during the second period.

Conclusions: Continuous surveillance is imperative for monitoring the local epidemiology and for developing local treatment guidelines.

Background: Sporadic abdominal desmoid tumors are rare and data on these tumors as a distinct disease entity are lacking. Previous abdominal surgery, trauma, pregnancy and estrogen intake are considered risk factors. Although desmoidsare benign, invasion and a high recurrence rate are common.

Objectives: To evaluate outcomes of surgery for this rare disease.

Methods: Since 1995, 16 patients with pathologically confirmed desmoid tumor were operated on in our center. All familial adenomatous polyposis patients were excluded. A retrospective analysis of data was performed.

Results: Of the 16 patients 12 (75%) were females. Mean age was 40.5 years (range 24-70). Thirteen patients were symptomatic and 3 were incidentally diagnosed. All patients presented with an isolated mass; 7 (50%) originated in the abdominal wall, 6 (37.5%) were retroperitoneal and 3 were (18.8%) mesenteric. All tumors except one were completely excised. Morbidity was low with no mortality. One patient was reoperated due to involved margins. None of the patients had recurrence within a median follow-up of 64 months (range 5-143).

Conclusions: The perception of sporadic abdominal desmoids as tumors with a high recurrence rate (20-70%) is probably incorrect. Adequate surgery with wide margins leads to a very low recurrence rate; cure is a legitimate goal.
 

Background: Women frequently suffer perineal trauma while giving birth. Interventions to increase the possibility for an intact perineum are needed.

Objectives: To evaluate the effectiveness of antenatal perineal massage in increasing the likelihood of delivering with an intact perineum.

Methods: This single blinded prospective controlled trial included 234 nulliparous women with a singleton fetus. Women allocated to the study group were instructed to practice a 10 minute perineal massage daily from the 34th week of gestation until delivery. Primary outcome measures included the episiotomy rate; first, second, third and fourth-degree perineal tear rates; and intact perineum. Secondary outcomes were related to specific tear locations and the amount of suture material required for repair.

Results: Episiotomy rates, overall spontaneous tears and intact perineum rates were similar in the study and control groups. Women in the massage group had slightly lower rates of first-degree tears (73.3% νs. 78.9%, P = 0.39) and slightly higher rates of second-degree tears (26.7% νs. 19.3%, P = 0.39), although both of these outcomes did not reach statistical significance. The rates of anterior perineal tears were significantly higher in the massage group (9.5% vs. 3%, P = 0.05), whereas internal lateral tears rates were slightly lower but without statistical significance (11.5% νs.13.1%, P = 0.44).

Conclusions: The practice of antenatal perineal massage showed neither a protective nor a detrimental significant effect on the occurrence of perineal trauma.
 

Background Drug-specific CD8+ TH1 lymphocytes have been found in the peripheral blood and involved skin of patients with drug-induced bullous exanthems.

Objectives To determine whether the interferon-gamma release test can identify culprit drugs in pemphigus patients.

Methods Clinical and laboratory workup for pemphigus was performed in 14 pemphigus vulgaris patients who had been exposed to drugs, and the IFNl[1] release test was conducted on their lymphocytes from heparinized venous blood cultured with medium, phytohemagglutinin and one of 32 drugs, or medium and phytohemagglutinin alone.

Results Ten of the patients and 13 of the 32 drugs exhibited a positive response to the test. Eight of the 10 patients with positive IFNl test results had a less severe course of the disease, with fast reduction in steroid dosage.

Conclusions The findings demonstrate both the ability of the IFNl release test to identify drugs that can induce pemphigus, and its usefulness in the diagnostic workup of pemphigus patients.

Background: Chronic obstructive pulmonary disease is an increasing cause of chronic morbidity and mortality around the world. The major cause of the disease is smoking. Despite the gravity of the problem there is no knowledge of its rate in the Israeli smoking population.

Objectives: To assess the prevalence of COPD[1]and early lung cancer among smokers.

Methods: People aged 45 up to 75 with a history of at least 20 pack-years cigarette smoking, including quitters, were screened for COPD. They were interviewed and a spirometry was performed.

Results: Of the 1150 people recruited 92% underwent and performed acceptable spirometry; 22% of these subjects had airflow limitation and were diagnosed with COPD according to the GOLD classification. Only 4% had been diagnosed as COPD prior to this screening. The majority of those tested were unaware of or unconcerned about developing the disease. There was no correlation between pack-years smoking and development of COPD, but there was a relative correlation of pack-years smoking and severity of COPD, particularly in the older group only (r = 0.42).

Conclusions: About one-fifth of the smokers aged 45 and up developed COPD. There is a significant gap between the disease distribution and its awareness in the population at risk. The need for a national screening program and early diagnosis of COPD in people at risk is needed.

Background: In an era of increasing antimicrobial resistance, knowledge of local antimicrobial susceptibility patterns of common uropathogens is essential for prudent empiric therapy of community-acquired urinary tract infections.

Objectives: To define antimicrobial susceptibility of Gram-negative uropathogens in northern Israel over a 10 year period and to compare it with antibiotic-use patterns in the same community.

Methods: We tested the susceptibility of all Gram-negative urinary isolates from outpatients at HaEmek Medical Center over the years 1995, 1999, 2002 and 2005 to common antimicrobial agents. MIC₉₀ of Escherichia coli to some of these agents was determined and antibiotic consumption data over the years 2000–2005 (DDD/1000/day) were obtained.

Results: We observed a rise in susceptibility rates of E. coli to amoxicillin-clavulanate, trimethoprim-sulfamethoxazole and nitrofurantoin and of other Gram-negative isolates to amoxicillin-clavulanate, ceftriaxone and cephalothin. Susceptibility rates of all Gram-negative uropathogens to ciprofloxacin decreased significantly. MIC₉₀ of E. coli for all drugs tested remained stable. There was a significant decrease in the use nitrofurantoin and TMP-SMX[1] and a significant increase in the use of ampicillin, cephalothin and ceftriaxone.

Conclusions: Antibiotic resistance patterns mostly remained unchanged or improved slightly. There was, however, a constant decrease in susceptibility of all Gram-negative uropathogens to ciprofloxacin. Antibiotic use patterns could not explain the changes seen in antibiotic susceptibility patterns.

Background: Depression is a leading cause of morbidity, disability and health care utilization. It is commonly encountered in primary care settings yet is often missed or suboptimally managed.

Objective: To summarize studies conducted in Israel on the prevalence of depression in primary care settings, its correlates, and predictors of treatment and outcome, and to discuss their implications for clinical practice and public health policy.

Methods: An electronic search was conducted using the MEDLINE and PsychINFO databases. The inclusion criteria were original studies that assessed aspects of depression in a population aged 18 or older, were conducted in primary care settings in Israel, and with sufficient detailed description of depression-related measures, study sample and outcome measures. Twelve articles reporting results from 7 studies met these criteria.

Results: The prevalence of current depression in primary care varied considerably across studies: 1.6–5.9% for major depression, 1.1–5.4% for minor depression, 14.3–24% for depressive symptoms. Depression was consistently related to female gender and few years of education, and was associated with disability, decreased quality of life, and increased health-related expenditure. Many cases of depression were undiagnosed and most patients had persistent depression or achieved only partial remission.

Conclusions: Depression represents a serious challenge for the primary health care system in Israel. Greater efforts should be focused on screening and treating depression in primary care. However, the studies reviewed here used different methodologies and assessed different aspects of depression, and, therefore, should be generalized cautiously. Systematic research on the prevalence, correlates and management of depression in primary care, with emphasis on collaborative care models, is strongly needed to inform research, clinicians and health care policy makers.

Background: Patients with severe persistent asthma despite GINA 2002 step 4 treatment are at risk for asthma-related morbidity and mortality. This study constitutes the Israeli arm of the international INNOVATE study.

Objectives: To determine the efficacy and safety of Xolair® as an add-on treatment in patients with severe persistent asthma.

Methods: Asthma patients (age 12–75 years) not controlled with high dose inhaled corticosteroids and long-active beta-2 agonists were randomized to receive either Xolair® or placebo for 28 weeks in a double-blind study in two Israeli centers.

Results: Thirty-three patients, 20 females and 13 males, mean age 54 ± 11.7 years, were included in the Israeli arm of the INNOVATE study. There were neither major adverse events nor withdrawals from the study. Xolair® (omalizumab) significantly reduced the rate of clinically significant asthma exacerbations (55% reduction) and all asthma-related emergency visits (53% reduction).
Conclusions: In patients with severe persistent difficult-to-treat asthma, despite regular treatment with LABA[1] and inhaled corticosteroids (GINA 2002 step 4), Xolair® is a safe and effective treatment
