Background: The prevalence of thyroid dysfunction in early pregnancy in Israel is not known.

Objectives: To assess the rate of abnormal thyroid-stimulating hormone (TSH) tests in low risk pregnant women attending a community clinic in Israel.

Methods: We conducted a retrospective analysis of the charts of low risk pregnant women (n=303) who had undergone a TSH screening during the first trimester of pregnancy at Clalit Health Services Women's Health Centers in Ashkelon and Tel Aviv. The TSH normal range during first trimester was considered to be 0.1–2.5 mIU/L.

Results: The TSH levels ranged from 0.04 to 13.3 mIU/L (median 1.73 mIU/L, mean 1.88 mIU/L). The rate of abnormal TSH was 25.6%, with low TSH 2.3% and high TSH 23.4%. The prevalence of abnormal TSH was not influenced by gravidity (primigravidas versus multigravidas) or place of residence (Ashkelon or Tel Aviv).

Conclusions: In view of the high prevalence of abnormal TSH (25.6%) in pregnant women in Israel during the first trimester, a universal country-wide screening should be considered.

Background: The management of sexual assault victims comprises complex medical, psychological, social and judicial care that was previously provided by various disciplines at several distant locations. This novel concept is the delivery of comprehensive care to victims of sexual assault at one location 24 hours a day.

Objectives: To describe the characteristics of sexual assault victims, their assailants, the assault and the treatment, and provide descriptive data on the evidentiary examination.

Methods: We performed a retrospective analysis of the charts of all sexual assault victims presenting to the Regional Israeli Center for Care of Sexual Assault Victims between October 2000 and July 2010. The center, the first in Israel, provides comprehensive care to victims of sexual assault in one location 24 hours a day using a multidisciplinary approach.

Results: The study group comprised 1992 subjects; 91.5% of the victims were females and 8.5% were males, and the age ranged from 1 to 88 years (mean age 22.3 years). Of the 1992 victims, 1635 were single (82.2%), 195 were divorced (9.8%), 141 were married (7.1%), 18 were widowed (0.9%) and 3 were unspecified. The assailant was a stranger in 794 (39.8%) of the cases, someone familiar to the victim in 786 cases (39.0%), a partner in 127 cases (6.4%), a family member in 117 cases (5.9%), someone met via the internet in 53 cases (2.7%), an authority figure in 39 cases (2.0%), and unspecified in 76 (3.9%). In the majority of cases the attack occurred either in the evening or at night (71.7%).

Conclusions: We identified several risk factors for sexual assault that can be used in prevention programs. The sexual assault victim in our study tended to be a young, single woman who was attacked by a familiar assailant in the evening or at night. Our center provides comprehensive care to victims 24 hours a day at one location and includes a team of forensic, psychological, physical and legal specialists.
 

Background: Fatigue is a common complaint in primary care and has a broad differential diagnosis, making the approach complex and often ineffective.

Objectives: To follow the course of adults without a significant known background disease who complain of fatigue for the first time, and to characterize the family physician’s approach.

Methods: The study population comprised a random sample of 299 patients aged 18–45 who presented with fatigue as a first-time single complaint to their family physician. Excluded were patients with chronic diseases or states that may include signs of fatigue. We analyzed the index encounter data, the diagnostic and laboratory tests, the medications prescribed and the one year clinical outcome.

Results: Seventy percent were women, average age 30.5 years, and 69% had no known co-morbidities; 57% of the patients were physically examined at the first visit and most (78.6%) were sent for laboratory analysis. Five percent of laboratory tests were positive. Eighty patients (26.8%) were given a specific diagnosis, with the leading diagnoses being anemia and infectious diseases; 18.7% were given sick leave at the first visit. Fatigue was more common in early summer.

Conclusions: The majority of young healthy patients complaining of fatigue are not diagnosed with an organic physiological disorder. Many of the study patients were sent for laboratory tests but in most cases these tests were not contributory to the diagnosis or management. It seems likely that the most efficient strategy would be watchful follow-up with a minimum of testing.

Background: On 4 February 2008, two terrorists armed with suicide bombs arrived at the open market in the southern Israeli city of Dimona. One detonated his bomb at approximately 10:30 a.m. causing multiple casualties. Short-term emotional effects and acute stress reactions usually appear among survivors after such incidents.

Objectives: To compare the differences in emotions and in disturbances of daily life activities that emerge a couple of days following such an event and to identify patterns of stress development among resilient and low-resilient members of the population in Dimona and in the general population of Israel.

Methods: A telephone survey of two randomly selected representative samples of adults (428 Israeli residents and 250 Dimona residents) was conducted 2 days after the event.

Results: A higher prevalence of stress and fear and a lower prevalence of joy were reported among the population of Dimona compared to the general population in Israel (P < 0.05). Differences were also recorded when the population of Dimona was categorized by their personal degree of resilience (P < 0.05). A higher prevalence of disturbances in daily life activities and changes in leisure activity was found in the low-resilient population in Dimona (P < 0.01).

Conclusions: This study demonstrates that following a public terror event, self-reported low-resilient subjects have a higher prevalence of disturbances in daily life activities, as well as adverse emotional responses. These differences must be addressed by the relevant social service agencies for immediate public intervention

Background: Little is known of the risk factor disparities in first stroke among Jewish and Arab patients undergoing rehabilitation in Israel.

Objectives: To investigate the age, gender and risk factor disparities in first stroke among Jewish (immigrant and non-immigrant) and Arab patients undergoing rehabilitation and to compare the prevalence and odds ratio of stroke risk factors in these patients.

Methods: The database of the Department of Neurological Rehabilitation C at Loewenstein Rehabilitation Center was used to investigate first ischemic and hemorrhagic stroke patients admitted for hospital rehabilitation over a 15 year period, January 1993 to December 2008. Particular attention was paid to age, gender and risk factor disparities.

Results: The 2000 patients with first stroke who were included in the study were grouped as Jewish (immigrant and non-immigrant) and Arab (237 Arabs, 370 non-immigrant Jews and 1393 immigrant Jews). A high percentage of Arab patients were found to have hypertension and diabetes mellitus, while a high percentage of Jewish immigrants had stenosis of the internal carotid artery.

Conclusions: The study demonstrated some differences in the effect of risk factors between the groups. It may be important to address such differences when developing stroke preventative strategies in this population of Jewish and Arab stroke survivors in Israel.
 

Background: Optimil® is an infant formula, manufactured in Israel and introduced to the market in May 2008.

Objectives: To assess, for the first time, the effect of this formula on infant growth.

Method: The study group comprised 52 infants who for the first 6 months of life consumed Optimil, which constituted at least 25% of their total daily intake. Anthropometric data were collected from the records of the well-baby clinics. Weight, length and head circumference at baseline and 3 months thereafter were converted to gender and age-matched standard deviation Z-scores. As an exploratory uncontrolled analysis, questionnaires were sent to the caregivers to assess satisfaction with the formula and to note the rate of constipation, irritability and vomiting as well as apparent palatability.

Results: The baseline Z-scores of all three parameters were below zero but increased significantly after 3 months (-0.2 ± 0.88 to 0.12 ± 0.88, P = 0.013 for weight; -0.44 ± 0.87 to 0.10 ± 0.72, P < 0.001 for length; and -0.58 ± 0.78 to -0.1 ± 0.76, P < 0.001 for head circumference). There was a significant dose-response effect of the formula with weight gain. The formula was generally well accepted, with 8% constipation, 8% vomiting and 6% significant irritability.

Conclusions: This study provides the first evidence that infants consuming Optimil under age 6 months have adequate growth. Nonetheless, breastfeeding during this period should be preferred in almost all cases.

Background: Myocardial blush grade is a useful marker of microvascular reperfusion that may influence left ventricular dilatation.

Objectives: To assess the impact of myocardial blush grade on LV[1] remodeling in patients undergoing successful primary  PCI³ for first anterior ST elevation myocardial infarction.

Methods: In 26 consecutive patients MB[2] grade was evaluated immediately after primary PCI[3]. Each patient underwent transthoracic echocardiography at 24 hours and 6 months after PCI for evaluation of LV volumes. LV remodeling was defined as an increase in end-diastolic volume by ≥ 20%.

Results: The presence of myocardial reperfusion (MB 2-3) after primary PCI was associated with a significantly lower rate of remodeling than the absence of myocardial reperfusion (MB 0-1) (17.6% vs. 66.6%, P = 0.012). Accordingly, at 6 months, patients with MB 2-3 had significantly smaller LV end-diastolic volume (94 ± 21.5 ml vs. 115.2 ± 26) compared with patients with MB 0-1. In univariate analysis, only MB (0-1 versus 2-3) was associated with increased risk of LV remodeling (odds ratio 9.3, 95% confidence interval 1.45–60.21, P = 0.019).

Conclusions: Impaired microvascular reperfusion, as assessed by MB 0-1, may be associated with LV remodeling in patients with STEMI[4] treated successfully with primary PCI.

Background: Tubeless percutaneous nephrolithotomy is defined as PCNL[1] without postoperative nephrostomy tubes. It is reported to reduce postoperative pain, hospital stay and recovery time. To date the procedure has been reserved for selected patients.

Objectives: To assess our initial experience in extending the implementation of tubeless PCNL without preoperative patient selection.

Methods: All consecutive PCNLs performed during 2004–2008 were evaluated. Tubeless PCNL was performed when residual stones, bleeding and extravasation were excluded intraoperatively. Staghorn stones, stone burden, supracostal and multiple accesses, anatomic anomalies, solitary kidneys and operative time were not considered contraindications. We analyzed the clinical data and the choice of tubeless PCNL over time.

Results: Of 281 PCNLs performed during the study period, 200 (71%) were tubeless. The patients' average age was 53 years (range 28–82 years), the stone burden was 924 mm² (400–3150 mm²), operative time was 99 minutes (45–210 min), complication rate was 14% and immediate stone-free rate 91%. There were 81 conversions to standard PCNL (29%) due to expected second-look (n=47, 58%), impression of bleeding (n=21, 26%), suspected hydrothorax (n=7, 9%) and extravasation (n=6, 7%). The transfusion rate was 1%. The median hospital stay was 1 day (1–15 days) and recovery time 7 days (5–20 days). The rate of implementing the tubeless procedure increased steadily along time from 46% to 83% (P = 0.0001). 

Conclusions: Tubeless PCNL can be safely and effectively performed based on intraoperative decisions, without preoperative contraindications. They are easily accommodated by experienced endourologists and provide real advantages.

Background: Cancer is a leading cause of mortality worldwide. The most effective way to combat cancer is by prevention and early detection.

Objectives: To evaluate the outcome of screening an asymptomatic population for the presence of benign and neoplastic lesions.

Methods: Routine screening tests for prevention and/or early detection of 11 common cancers were conducted in 300 consecutive asymptomatic, apparently healthy adults, aged 25–77 years. Other tests were performed as indicated.

Results: Malignant and benign lesions were found in 3.3% and 5% of the screenees, respectively, compared to 1.7% in the general population. The most common lesions were in the gastrointestinal tract followed by skin, urogenital tract and breast. Advanced age and a family history of a malignancy were associated with increased risk for cancer with an odds ratio of 9 and 3.5, respectively (95% confidence interval 1.1–71 and 0.9–13, respectively). Moreover, high serum C-reactive protein levels and polymorphisms in the APC and CD24 genes indicated high cancer risk. When two of the polymorphisms existed in an individual, the risk for a malignant lesion was extremely high (23.1%; OR[1] 14, 95% CI[2] 2.5–78).

Conclusions: Screening asymptomatic subjects identifies a significant number of neoplastic lesions at an early stage. Incorporating data on genetic polymorphisms in the APC and CD24 genes can further identify individuals who are at increased risk for cancer. Cancer can be prevented and/or diagnosed at an early stage using the screening facilities of a multidisciplinary outpatient clinic.
