Background: The fish-eating habits of Israelis who present with impacted fish bones in the aerodigestive tract are unknown.

Objectives: To retrospectively investigate the relation between an impacted fish bone in the aerodigestive tract, the species of fish, and the place of occurrence in an Israeli population.

Methods: The current prospective observational study included all patients with aerodigestive impacted fish bones who were treated in our emergency department from 1 September 2008 to 30 September 2009. The data retrieved from their medical records included age, gender, place of event (at home or elsewhere), species of fish, and method of removing the bone.

Results: A total of 108 patients aged 1.5–87 years (median 48 years), 52.8% female, met the study criteria. Most (87%) of the events occurred at home, and 50.9% occurred during the weekend (Friday- Saturday). The bones were from low-priced fish (e.g., carp, hake) in 62% of the cases, high-priced fish (e.g., salmon, red snapper) in 30.5%, and of unknown species in 10.2%. The proportion of cases in which the fish bone belonged to a high-priced fish eaten out of the home was significantly higher than the cases in which a low-priced fish was eaten at home (64.3% vs. 22.3%, P = 0.04). One hundred bones were removed during direct oral inspection and 8 bones were removed under general anesthesia by endoscopy.

Conclusions: Most fish bone impactions in the aerodigestive tract in central Israel involve low-priced fish and take place at home over the weekend.
 

Background: Infertility is one of the most prevalent health disorders in young adults.

Objectives: To study the distribution of causes of infertility in couples referred to primary infertility clinics in Israel.

Methods: Data for a 9 year period were derived from two clinics of major women's hospitals run by the country's largest health insurance funds. All patients were treated by one physician. Laparoscopy was not performed to rule out endometriosis.

Results: Of the 2515 couples identified, 1991 (79.2%) had a definitive diagnosis following complete workup (including hysterosalpingography). Mean age was 29.6 ± 6.0 years; mean duration of infertility was 1.7 ± 1.8 years. Primary infertility accounted for 65% of cases. Causes of infertility were male factor (45%), oligo-ovulation disorders (37%), and tubal damage (18%). Infertility factors were identified in the woman alone in 30.6% of cases and the man alone in 29.2%. Two combined infertility factors were found in 18% of patients, and three combined factors in 0.5%. The rate of unexplained infertility (which probably includes non-tubal endometriosis) was 20.7%.

Conclusions: As male factor accounts for almost half of all cases of infertility in couples, sperm analysis is mandatory before any treatment.
 

Objectives: To assess our experience with perichondritis in a large group of patients hospitalized with this entity.

Methods: We retrospectively studied 114 patients who were admitted with perichondritis during 1987–2004, including their demographic details, medical history, current illness, etiology, pathogens and treatments. 

Results: The patients’ mean age was 41.8 ± 20.7 years. In more than half of the patients the etiology could not be determined. Forty-seven patients (41%) were treated prior to hospitalization for an average of 2.5 ± 1.9 days. Eight patients (7%) required surgical intervention. Pseudomonas aeruginosa was found to be the predominant organism (69% of available isolates) and was associated with a more advanced clinical presentation and longer hospitalization (P = 0.008). 

Conclusions:  Perichondritis develops in many cases after apparent minor trauma. Since P. aeruginosa is probably the predominant pathogen, initial treatment should include anti-pseudomonal antibiotics.

Background: Concomitant human immunodeficiency virus and human papillomavirus infection increases both HPV[1] persistence and the risk of invasive cervical cancer. An estimation of HPV prevalence among HIV[2]-positive women in Israel would contribute to improving care for this population and preventing morbidity and mortality related to cervical cancer.

Objectives: To determine the prevalence of HPV infection and cervical cytology abnormalities, and to assess the possible influence of HIV infection on HPV carriage in HIV-positive women attending the Infectious Disease Clinic at Soroka University Medical Center.

Methods: The study population included 84 HIV-seropositive women. They were examined by a gynecologist and screened for HPV genotyping, and Pap smears were obtained for cervical cytology. Demographic, behavioral, and HIV infection variables were also recorded and analyzed.

Results: Forty-nine (58.3%) of the study participants were HPV-positive; 34 of them had oncogenic genotypes. Young age (< 16 years) at first sexual intercourse was the only variable significantly associated with HPV infection (P < 0.05). Abnormal cervical cytology was present in 17 women (20.3%); 21 women were referred to colposcopy, which was abnormal in 9 (10.7%).

Conclusions: The prevalence of HPV carriage among HIV-positive woman in our study was slightly higher than published elsewhere. The prevalence of pathological cervical cytology was much higher than in the general population. An extremely high prevalence of pathological colposcopies requiring further treatment was found. Screening for HPV and premalignant changes in the uterine cervix is highly recommended in the HIV-seropositive population. We suggest that colposcopy be considered part of the routine workup in HIV-seropositive woman.

Background: In infants, small volume nebulizers with a face mask are commonly used to facilitate aerosol therapy. However, infants may be disturbed by mask application, causing poor mask-to-face seal and thus reducing the dose delivered.

Objectives: To compare lung function response to bronchodilator nebulization via two delivery devices: hood versus mask.

Methods: We studied 26 recurrently wheezy infants aged 45.8 weeks (95% confidence interval 39.6–52.0). Inhalations of 0.30 mg/kg salbutamol were administered in two alliqots 30 minutes apart using mask and hood in alternating order (M+H or H+M). Response to inhalations was measured by maximal expiratory flows at functional residual capacity at 5 minute intervals after each dose, and area under the VmaxFRC[1] curve was documented.

Results: A small but significant response to salbutamol was observed following the second inhalation with VmaxFRC, improving by 31.7% (7.2–56.2, P < 0.02) and AUC[2] by 425 %•min (-154, 1004; P < 0.02). The improvement following salbutamol was similar by both delivery modalities but with a small but significantly better response when H was used after M (P < 0.01).

Conclusions: Nebulized salbutamol induced a variable but positive response in wheezy infants. Salbutamol via hood was as effective as conventional face mask delivery. Since it is simple and patient-friendly, it could replace the face mask method particularly with uncooperative infants.

Background: The European Quality of Life 5-Dimensions questionnaire is one of the most commonly used measures of health-related quality of life.

Objectives: To present the feasibility, reliability, and validity of the Hebrew version of the EQ-5D[1].

Methods: We conducted face-to-face interviews with a representative sample (n=1666) of the Israeli Jewish population. The data collected included demographic and medical information, and self-valuation of health using the EQ-5D descriptive system, Visual Analogue Scale and Time Trade-Off. Construct validity was assessed by assuming that older individuals, those with a greater burden of diseases, and those reporting experience with their own severe illness would have lower EQ-5D indexes, VAS[2] and TTO[3] values. Test-retest reliability was assessed in a small sample (n=50) that was reevaluated after a 3 week interval.

Results: Test-retest reliability of the EQ-5D and VAS was very high (r ≥ 0.85). Reliability of the TTO was moderate (r = 0.48). There were significant differences in the EQ-5D index, profiles, VAS and TTO between healthy and sick respondents and younger and older respondents, indicating good validity of the instrument.

Conclusions: The Hebrew translation of the EQ-5D is a practical, reliable and valid instrument for assessing the health-related quality of life of the general Israeli Jewish population.

Background: The incidence of cutaneous leishmaniasis in northern Israel began to rise in 2000, peaking at 41.0 per 100,000 in the Kinneret subdistrict during the first half of 2003.

Objectives: To examine the morbidity rates of CL[1] in northern Israel during the period 1999–2003, which would indicate whether new endemic areas were emerging in this district, and to identify suspicious hosts.

Methods: The demographic and epidemiologic data for the reported cases (n=93) were analyzed using the GIS and SPSS software, including mapping habitats of suspicious hosts and localizing sites of infected sand flies.

Results: The maximal incidence rate in the district was found in the city Tiberias in 2003: 62.5/100,000 compared to 0–1.5/100,000 in other towns. The cases in Tiberias were centered on the peripheral line of two neighborhoods, close to the habitats of the rock hyraxes. Sand flies infected with Leishmania tropica were captured around the residence of those affected. Results of polymerase chain reaction were positive for Leishmania tropica in 14 of 15 tested patients.

Conclusions: A new endemic CL area has emerged in Tiberias. The most suspicious reservoir of the disease is the rock hyrax.

Background: The rate and duration of breastfeeding in Ethiopia is very high. Factors that could affect breastfeeding among women emigrating to Israel include the desire to adopt "modern" behaviors, the availability of infant formulas, and the greater awareness of AIDS and fear of transmission via breast milk.

Objectives: To examine the rate and duration of breastfeeding among recent Ethiopian immigrants to Israel.

Methods Using a structured questionnaire we interviewed 93 Ethiopian born mothers of children aged 2 months to 5 years living in northern Israel.

Results: Ninety-two percent of the children born in Ethiopia were exclusively breastfed as compared to 76.3% of the Israeli born children, in whom the rate of mixed feeding was 18.3%. Although the duration of breastfeeding of the youngest child was significantly shorter than of the firstborn (20.1 vs. 24.8 months), it remains much longer than the average duration for native Israeli mothers. No association was seen between breastfeeding rate or duration and the years since immigration, work outside the home or exposure to formula. The women’s attitude towards breastfeeding was positive despite the lack of specific knowledge concerning breast milk and infant formulas.

Conclusions: Breastfeeding patterns among Ethiopian women have changed since their immigration to Israel. These changes probably reflect the cultural and societal pressures to acculturate to the mores of the adopted society. Reinforcing traditional family and peer support for these women is important to preserve breastfeeding in this population. This should be done within the context of changes in the support for breastfeeding in the general Israeli society.

The courts have recently become increasingly involved in the administration of compulsory psychiatric services in Israel. Data reveal a gradual increase in the rate of court-ordered hospitalizations according to Section 15 of the Law for the Treatment of the Mentally Ill. This paper examines the implications of this trend, particularly the issues of security and safety in psychiatric hospitalization. We present highlights from extensive British experience, focusing on the implications on forensic psychiatry in Israel. We review the development of the hierarchy of security in the British psychiatric services, beginning in the early 1970s with the establishment of the Butler Committee that determined a hierarchy of three levels of security for the treatment of patients, culminating with the establishment of principles for the operation of medium security units in Britain (Read Committee, 1991). These developments were the basis for the forensic psychiatric services in Britain. We discuss the relevance of the British experience to the situation in Israel while examining the current status of mental health facilities in Israel. In our opinion, a safe and suitable environment is a necessary condition for a treatment setting. The establishment of medium security units or forensic psychiatry departments within a mental health facility will enable the concentration and classification of court-ordered admissions and will enable systemic flexibility and capacity for better treatment, commensurate with patient needs.

Background: Data regarding the validity of self-reported weight and height in adolescents are conflicting.

Objectives: To evaluate the validity of self-reported weight and height among 13–14 year old schoolchildren. 

Methods: We conducted a cross-sectional study of 517 schoolchildren aged 13–14 years and compared self-reported and measured weight and height by gender, population group, parental education and crowdedness.

Results: Females under-reported their weight on average by 0.79 ± 5.46 kg (P = 0.03), resulting in underestimation of the body mass index with borderline significance (mean difference 0.28 ± 2.26 kg/m², P = 0.06). Males over-reported their height on average by 0.75 ± 5.81 cm (P = 0.03). Children from less crowded homes (≤ 1 person per room) overestimated their height more than children from more crowded homes, resulting in a significant underestimation of BMI[1] (mean difference between reported BMI and measured values was 0.30 ± 2.36 kg/m², P = 0.04). Measured BMI was a significant predictor of the difference between self-reported and measured BMI, adjusted for gender, population group, parents' education, and crowdedness (β = -0.3, P < 0.0001). As a result of this reporting bias, only 54.9% of children with overweight and obesity (BMI ≥ 85th percentile) were classified correctly, while 6.3% of children were wrongly classified as overweight and obese. The largest difference in BMI was observed in obese females (4.40 ± 4.34) followed by overweight females (2.18 ± 1.95) and underweight females (-1.38 ± 1.75). Similar findings were observed for males, where the largest difference was found among obese males (2.83 ± 3.44).

Conclusions: Studies based on self-reported weight and height in adolescents may be biased. Attempts should be made to correct this bias, based on the available data for each population.

Background: Ultrasound examination of the fetus enables diagnosis of many major malformations during pregnancy, providing the possibility to consider interruption of the pregnancy. As a result, in many cases the incidence of malformations at birth does not represent their true incidence.

Objectives: To determine the impact of prenatal diagnosis and termination of pregnancy on the relative incidence of malformations at birth among Jews and Muslim Arabs in Israel.

Methods: Data on selected major malformations in 2000–2003 were collected from the two large central databases of the Ministry of Health and the Central Bureau of Statistics which contain information regarding births, stillbirths and terminations of pregnancies.

Results: For many malformations the total incidence was much higher than the incidence at birth. For almost all of the malformations studied, the total incidence was higher in Muslims than in Jews and the differences were further accentuated among the liveborn because of the differences in the rate of pregnancy terminations.

Conclusions: In order to detect possible influences of environmental or genetic factors on major malformations in Israel, it is critical to look at data including pregnancy terminations, stillbirths and live births.

Background: Poisonings are a significant cause of pediatric morbidity and mortality. The Israel Poison Information Center provides clinical consultations on poisonings and drug information 24 hours a day.

Objective: To evaluate epidemiologic characteristics of pediatric poison exposures in Israel.

Methods: We reviewed computerized queries and performed a descriptive analysis of the Poison Center database pertaining to patients less than 18 years old during 2007.

Results: A total of 15,005 pediatric poison exposures were recorded, 80.3% of them occurring in children under 6 years old. Of the calls to the Poison Center, 78.6% were made by the public, 20.7% by physicians, and in 74.4% the call was within 2 hours of exposure. Most exposures occurred at home (89.3%) and were unintentional (89.5%). Among adolescents, most exposures were intentional (49.3%, 38.2% suicides), the time lapse until consultation was longer (37% > 2 hours), and more physicians (54.8%) consulted the Poison Center. Most cases were asymptomatic or mildly affected (92.3%), 54.4% in adolescents. The commonest substances involved in single poison exposure were detergents, antimicrobials, topical preparations, acetaminophen and scale removers; in adolescents the most common substances were acetaminophen, methylphenidate, non-steroidal anti-inflammatory drugs, atropine and ethanol. Moderate to severe toxicity was commonly associated with organophosphates, alkali, ethanol, Vipera palaestinae and neuroleptics. Most patients could be observed at home (66.6%), while more adolescents were referred to emergency departments (42.2% vs. 9.9%) or hospitalized (14.5% vs. 1.9%).

Conclusions: Pediatric poisonings are a significant health problem. The magnitude of the problem is greater in the young age group but more severe in adolescence, probably due to deliberate self-poisoning. Greater national efforts should be directed towards improved poison prevention, rational management of pediatric poisoning, and creating a national poisoning registry.
 

Background: Community-acquired pneumonia is a common infection and is associated with high rates of morbidity and mortality. Most patients with CAP[1] are treated empirically.

Objectives: To identify common pathogens causing CAP in hospitalized patients in northern Israel and to evaluate the correlation between etiology and disease severity.

Methods: We conducted a prospective study of patients with CAP hospitalized at HaEmek Medical Center, Afula. We collected demographic, clinical and laboratory data (blood and sputum cultures, serology, pneumococcal urinary antigen test, and respiratory multiplex-polymerase chain reaction from nasopharyngeal swab), and radiologic evaluation was performed.

Results: A total of 126 patients and 24 controls were enrolled. At least one pathogen was identified in 84 cases (66.7%), more than one in 43 patients (34.1%), and no pathogens in 42 (33.3%). Typical bacteria were found in 23 (18.3%), atypical bacteria in 66 (52.4%), and viruses in 42 (33.3%). The number (%) of patients with pathogens isolated was: Chlamydophila pneumoniae 26 (20.6%), Streptococcus pneumoniae 23 (18.3%), Mycoplasma pneumoniae 23 (18.3%), influenza virus A-B 20 (15.9%), Coxiella burnetti 8 (6.3%), and parainfluenza and adenovirus 13 (10.3%) each. A correlation was found only between a high PORT score on admission and S. pneumoniae, although atypical pathogens did not show class predominance.

Conclusions: S. pneumoniae, M. pneumoniae and C. pneumoniae were the most common pathogens isolated, while co-infection was very frequent. PORT score did not predict any of the pathogens involved. The choice of empiric antimicrobial treatment for CAP should be made according to local epidemiologic data.

Background: Guidelines are frequently under-implemented in older patients with heart failure. Octogenerians are often excluded from clinical trials.

Objectives: To characterize the clinical profile of the oldest-old (age ≥ 80 years) heart failure patients hospitalized in a subacute geriatric hospital and to evaluate their management and 1 year outcome.

Methods: Patient characteristics and in-hospital course were retrospectively collected. Diagnosis of heart failure was based mainly on clinical evaluation in addition to chest X-ray results and echocardiographic findings when available.

Results: The study population comprised 96 consecutive unselected heart failure patients hospitalized from January to June 2003. The patients were predominantly women (67%), aged 85 ± 5 years, fully dependent or frail with a high rate of comorbidities. Adherence to guidelines and recommended heart failure medications was poor. Their 1 year mortality was 57%. According to logistic regression analysis, predictors of 1 year mortality were lower body mass index (odds ratio 0.86, 95% confidence interval 0.78–0.96) and high urea levels (OR[1] 1.04, 95% CI[2] 1.02–1.06).

Conclusions: Our study confirms that the management of oldest-old heart failure patients hospitalized in a subacute geriatric hospital was suboptimal and their mortality was exceptionally high.
