Little is known about the courses, causes, and clinical features of anaphylaxis in children outside the USA and Europe. Our objective was to evaluate the events of anaphylaxis in children admitted to the Schneider Children's Medical Center of Israel, a major tertiary facility, over a 12-year period. Ninety-two children with anaphylaxis (50 boys, 42 girls) aged 14 days to 18 yr (mean, 7.4 yr) were hospitalized during the study period. The event occurred at home in 52 children (56%), in a medical institution in 24 (26%), outdoors in 13 (15%), at school in 2 (2%), and in an unspecified location in 1 (1%). The main causes were foods (43%), mainly milk and nuts, medications (22%), and hymenoptera venom (11%); in five children, anaphylaxis occurred during general anesthesia, and in 5, the causative agent could not be determined. Food-induced anaphylaxis tended to occur in younger children. Forty-eight children (52%) had a history of atopy (mainly asthma). Hospital treatment consisted of corticosteroids (85%), antihistamines (75%), epinephrine (72%), and β2 agonists (42%). Seven patients were admitted to intensive care units. There were no fatalities. EpiPen was used by only one of the 16 patients with more than one episode of anaphylaxis, indicating that patient and parent education in the application of the EpiPen needs to be improved.

Cow milk and milk products are the most common food products consumed in Israel; rates of allergy to cow milk exceed those of peanuts in infants and children. The aim of the present study was to evaluate retrospectively the clinical features and natural course of immunoglobulin (Ig) E-mediated cow milk allergy (CMA) in Israel. Data of children diagnosed with CMA from 1995 to 2003, were collected regarding age at first and most recent reactions, symptoms and signs, family history of atopy, other allergic diseases, emergency department visits, hospitalizations, and treatment. Patients with transient CMA were compared to those with persistent CMA (≥3 yr old). The study group consisted of 105 patients, 43 with transient CMA (age range: 0.48–11 yr). The remaining 62 patients (age range: 3–16.5 yr) did not achieve tolerance to cow milk during the follow-up period. No differences were found between the groups in mean age and symptoms and signs at the first allergic reaction and family history of atopy. Patients with persistent CMA had a higher rate of asthma than patients with transient CMA (61.2% vs. 18.6%, p < 0.001). Fifty patients with persistent CMA had 137 subsequent allergic reactions after diagnosis, 25% of the reactions were due to oral milk challenge at the clinic and 75% due to accidental exposure, of which 13% required an emergency department visit and 8%, hospitalization. Only 19% of the reactions were treated with epinephrine injection. In conclusion, in our experience, less than half of the children diagnosed with IgE-mediated CMA during 9 yr, outgrew it. The patients with persistent CMA have a higher prevalence of asthma compared with the general population or to children with transient CMA. The high number of recurrent allergic reactions due to accidental exposure and the low rate of epinephrine usage in these patients point to a need for better education of patients and their families.

Background: Chronic urticaria is defined by the presence of itchy wheals, sometimes accompanied by angioedema, lasting for at least 6 weeks. In children, most cases occur without an eliciting factor and are defined as chronic spontaneous urticaria (CSU). CSU affects up to 0.75% of children with a negative impact on quality of life and school performance. CSU is treated in adults with second-generation antihistamines, increased up to four times normal doses for second-line treatment. Omalizumab (a monoclonal antibody to IgE) may be recommended as third-line therapy. A similar protocol is used in children, yet little is known of its efficacy and safety., Objectives: To summarize our multi-center experience in treating children with recalcitrant CSU with omalizumab., Methods: A retrospective multi-center case series conducted in 5 tertiary care centers in Israel. Patients included were children <18 years old diagnosed with recalcitrant CSU who were treated with omalizumab. Patients were followed up throughout the duration of omalizumab therapy/symptom remission. Patients' electronic medical records were used to gather data., Results: Nineteen participants (11 F; 8 M) presented with CSU between ages 6 and 16.9 years. Sixteen (84%) responded to omalizumab, including children <12 years old, although two became non-responsive after 6-12 months of therapy. Another three patients (16%) were resistant to treatment, achieving remission through fourth-line (Cyclosporine A) or other therapies., Conclusion: Children with recalcitrant CSU, even those <12 years old, respond well to standard-dose, third-line omalizumab therapy at rates similar to adults. Yet, some cases may become non-responsive with ongoing treatment., (© 2020 Wiley Periodicals LLC.)

Objective: Asthma is one of the most common chronic diseases globally. Atopy, and especially allergic rhinitis (AR), was found as an important risk factor for asthma. The purpose of this study was to examine the association between different atopic parameters and military professions to the incidence of asthma., Methods: In a retrospective study, we included 128 591 Israel Defense Forces soldiers drafted between the mid-nineties to the early-2000s. We examined the incidence rates of asthma in relation to atopic background and to military profession., Results: The relative risk (RR) for the development of asthma in persons with a history of AR and the RR for asthma in atopics vs. nonatopics was 1.86 (95% CI: 1.57-2.21) and 1.73 (95% CI: 1.47-2.04), respectively. The RR for the development of asthma in persons with a history of AR was higher in Combat Units (CU) and Administrative and Driving units (ADU) (RR = 2.80; 95% CI: 2.09-3.76 and RR = 1.58; 95% CI: 1.19-2.12, respectively) than in Maintenance Units (MU) (RR = 1.27; 95% CI: 0.93-1.74). When comparing the risk for asthma amongst persons with AR, we found it lower in MU compared to ADU (RR = 0.65; 95% CI: 0.43-0.97). In atopics vs. non-atopics, the risk for asthma was higher in ADU as compared to other occupations., Conclusions: Atopy, particularly AR, is a risk factor for the development of new-onset asthma in young adults. Atopy has the highest significant effect in CU where the physical demands are higher.

Objective: The purpose of our study was to evaluate the influence of epidural anesthesia on the hearing system in women undergoing normal labor., Design: We examined two groups of patients: women with epidural anesthesia underwent four tests of distortion product otoacoustic emissions(DPOAEs): on admission, and fifteen minutes, one hour, and three hours after the last epidural bolus of local anesthetic. Auditory brainstem response (ABR) tests were performed on admission, and one hour, and three hours after the last epidural bolus. Women who gave birth without epidural anesthesia underwent DPOAEs tests on admission, during a uterine contraction, during active delivery, and three hours after labor. ABR tests were performed on admission, during a uterine contraction, and three hours after labor., Study Sample: twenty patients participated in the study. Twelve gave birth with epidural anesthesia and eight without anesthesia., Results: No significant changes in DPOAEs and ABR recordings were found between the two groups., Conclusions: Epidural anesthesia does not impair the sensory or the neural elements of the hearing system and therefore does not influence hearing.

IgA deficiency is the most common human primary immune-deficiency. We evaluated the clinical and immunological characteristics of selective IgA deficiency in children in Israel. The study group included 63 children diagnosed with IgA deficiency from 1987 to 2005. Mean follow-up time per child was 10.6 years. Average age at diagnosis was 10.5 years. In one child, the IgA deficiency was transient. Infectious diseases, mainly recurrent pneumonia and ear infection, were common and occurred in 25 patients (39.7%). Allergic diseases were documented in 20 (31.7%) of our patients. Thirteen children (20.6%) had autoimmune diseases. Malignancies were diagnosed in three children (4.8%), an association that has not been reported in previous series. IgA deficiency appears to be a risk factor for infections, allergic diseases, autoimmune conditions, and malignancy.

Objective: Peritonsillar abscess is the most common deep neck infection and still provides a challenge to care givers in terms of diagnosis and treatment in the pediatric population. This study reviews our experience over the years 2004-2007 at the Soroka University Medical Center in the southern district of Israel in treating children with peritonsillar abscess. We compared our results with data regarding peritonsillar abscess in adults., Methods: We performed a retrospective chart review of 126 children diagnosed and proved to have a peritonsillar abscess. Data regarding: age, sex, ethnicity, number of patients per year, seasonality, prior history of tonsillar infection, prior antibiotic treatment, length of hospitalization, surgical treatment, bacterial results and in hospital antibiotic treatment was collected from the medical charts of the patients., Results: The average age of children with peritonsillar abscess was 12.8 years. 92 patients (73%) were above 10 years of age. We did not find an increase in the number of children with peritonsillar abscess per year over the time period of the study. The number of patients with peritonsillar abscess was significantly higher in the autumn and spring, 79 (62.6%) patients did not have prior history of tonsillar infections and 64 (67.4%) children were treated with antibiotics prior to the diagnosis of an abscess. In 95 (75.4%) patients the drainage method was needle aspiration, in 30 (28.3%) patients incision and drainage was performed and only one patient underwent bilateral quinsy tonsillectomy (0.8%). The bacterial culture was negative in 37 (36.7%) patients. In 29 patients (45% of positive cultures) the causative organism was Streptococcus group A. Mixed culture was present in 10 (15.6%) patients, nine cultures (14%) were positive for anaerobes, alone or in combination with other pathogens. Eighty-one patients (64.2%) were treated with amoxicillin-clavulanate potassium, 24 (19%) received cefuroxime and 17 (13.5%) were treated with cefuroxime+ metronidazole. The average hospital stay was 3 days., Conclusion: Peritonsillar abscess, a potentially life threatening infection, is similar in presentation and bacteriology in the pediatric and the adult population. Based on our review we conclude that peritonsillar abscess in children can be effectively treated by the same methods used in the adult population.

The colorectal cancer (CRC) screening program in Israel offers the average-risk population fecal occult blood tests from the age of 50 years. Compliance, however, is very low, reaching only 6% of eligible persons in 2005. Our aim in this study was to describe the results of an improved CRC screening program directed at the in-house staff of Beilinson Hospital. All employees of Beilinson Hospital over age 50 years were sent a letter explaining the new CRC screening program and an accompanying questionnaire. Responders who reported a family history of CRC or related cancers or symptoms were offered colonoscopy; the remainder were offered sigmoidoscopy or, if they preferred, colonoscopy. Two hundred twenty of the 888 candidates (24.7%) completed the questionnaire, of whom 144 (16.2%) agreed to further investigation. These included 90 of 105 patients with a positive questionnaire and 20 of 115 with a negative questionnaire who underwent colonoscopy and 34 of 115 with a negative questionnaire who underwent sigmoidoscopy. The colonoscopy group included 26 of the 30 patients (86.6%) with a positive family history. Early-stage CRC was diagnosed in three patients (1.36%), all with a positive questionnaire. There were no pathologic findings on sigmoidoscopy. The sensitivity, specificity, and positive and negative predictive values of the questionnaire for identifying subjects with CRC or advanced adenoma were 100.00%, 18.86%, 2.27%, and 100.00%, respectively. In conclusion, using hospital facilities, we initiated a unique CRC screening program for employees. Our method may be applicable in other medical centers for the detection of adenomas and CRCs in the early, curative stages.

Successful colonoscopy depends on good preparation of the colon before the procedure. Inadequate preparation may lead to cancelled or repeat procedures and compromise patient safety, quality of care, and cost effectiveness. The primary aim of this study was to isolate factors that affect preparation success, especially in older, more severely ill, bedridden patients. The secondary aim was to examine the possible differences in preparation quality between ambulatory and hospitalized patients and the impact of a staff educational program on the preparation of hospitalized patients for colonoscopy. The study group included 303 consecutive ambulatory patients and 104 hospitalized patients referred for colonoscopy between January and March 2002, before the department introduced an educational program on colonoscopy preparation, and 310 ambulatory patients and 105 hospitalized patients referred for colonoscopy between January and March 2003. All patients completed an ad hoc questionnaire, and the findings were compared between ambulatory and hospitalized patients and between patients treated before and after the educational program. Polyethylene glycol was used significantly more often for colonoscopy preparation in hospitalized patients than in ambulatory patients (53.1% versus 8.8%; P=.0001). The hospitalized group was characterized by more incomplete or repeated colonoscopies and poorer preparation quality. On multivariate analysis, the variables found to be independent predictors of good preparation were successful patient completion of the preparatory procedure according to instructions, colonoscopy performed for follow-up after polypectomy, and preparation with sodium phosphate. The educational intervention had no impact on the quality of preparation. In conclusion, sodium phosphate preparation and complete adherence to preparation instructions are the most important factors for successful colonoscopy preparation. Current preparatory methods for hospitalized and severely ill patients need to be revised.

Background: The prevalence of allergic diseases has increased over the last 20 years in the Western world. Reports on the growing use of adrenaline auto-injectors (EpiPen and EpiPen Jr) in several countries may point to increased rates of anaphylactic reactions, increased awareness of the risk of anaphylaxis or both., Objectives: To evaluate the dispensing rate of EpiPen units in Israel from 1997 to 2004., Methods: The database of the General Health Services (Clalit) was searched to determine the number of EpiPen units dispensed each year from 1997 to 2004. Data on mortality from anaphylaxis were derived from the Central Bureau of Statistics using International Classification of Diseases, 10th revision codes., Results: The dispensing rate of EpiPen units rose gradually from 1689 in 1997 to 2981 in 2004; an overall increase of 76%. No case of death from anaphylaxis was reported from 1998 to 2000., Conclusions: The dispensing rate of adrenaline auto-injectors has increased considerably over the last 8 years in Israel, although to a lesser degree than in other countries. This is probably a reflection of updated medical policies, in accordance with the clinical guidelines for the management of anaphylaxis and improved public education. Further studies are needed to determine the prevalence of anaphylactic reactions in Israel.

Objectives: We evaluated the correlation of asymmetric hearing loss, in a random population of patients with mild to moderate sensorineural hearing loss, to several clinical factors such as age, sex, handedness, and noise exposure., Methods: We randomly selected, from 8 hearing institutes in Israel, 429 patients with sensorineural hearing loss of at least 30 dB at one frequency and a speech reception threshold not exceeding 30 dB. Patients with middle ear disease or retrocochlear disorders were excluded. The results of audiometric examinations were compared binaurally and in relation to the selected factors., Results: The left ear's hearing threshold level was significantly higher than that of the right ear at all frequencies except 1.0 kHz (p < .05). One hundred fifty patients (35%) had asymmetric hearing loss (more than 10 dB difference between ears). In most of the patients (85%) the binaural difference in hearing threshold level, at any frequency, was less than 20 dB., Conclusions: Age, handedness, and sex were not found to be correlated to asymmetric hearing loss. Noise exposure was found to be correlated to asymmetric hearing loss.

Background: Chronic frontal sinusitis is a relatively common condition, yet one with potential for complications. The treatment of chronic frontal sinusitis has always been a challenge for the otolaryngologist, and it remains so even in the age of endoscopic sinus surgery. Successful treatment is evaluated by both subjective (patient history) and objective (radiologic and endoscopic) criteria., Purpose: This article aims to present our experience in endoscopic surgery for chronic frontal sinusitis, with particular focus on the importance of the wide opening of the naso-frontal outflow tract, with maximal preservation of the mucosa in this area., Methods: During the period 1999 to 2001, 72 patients at the Soroka University Medical Center underwent endoscopic surgery for chronic frontal sinusitis. We reviewed the cases of fifty four patients of this group with a minimum six months follow-up. Patients who did not return for routine post-operative visits were excluded from this study. We evaluated and quantified subjective measurements including facial pain, nasal respiratory obstruction and hyposmia, and objective measurements, based on radiographic studies and endoscopic examination., Results: Most patients experienced improvement in all of the subjective categories, and particularly in the categories of facial pain/headache and nasal respiratory obstruction. Most patients who experienced this improvement had suffered from chronic pansinusitis., Conclusions: The endoscopic management of chronic frontal sinus disease is an effective treatment, when principles of wide sinus drainage with maximal mucosal preservation are observed. Most patients undergoing this type of procedure experience significant clinical and radiologic improvement in their condition.
