Background: In the last decade the use of different types of oral immunotherapy for food-allergic patients has increased with generally satisfactory outcomes. Cow’s milk and hen’s egg, a common element in the daily diet, have received the main interest. Most of these immunotherapy regimens are performed in the hospital, causing inconvenience for both children and their parents.

Objectives: To assess the efficacy and safety of a home-based oral immunotherapy regimen with raw pasteurized egg.

Methods: The study group comprised children aged 6 years and older with allergy to hen’s egg proteins, proven by positive skin prick-tests (SPT) and/or specific immunoglobulin E (sIgE) and positive open oral food challenge (OOFC) with boiled or raw egg. Patients who met the inclusion criteria and signed the informed consent form underwent egg immunotherapy according to an established schedule.

Results: The treatment was given to 31 of the 36 recruited patients: 80.6% of the intention to treat population achieved complete tolerance to the maximum dose equivalent to one raw hen’s egg, 3.2% achieved incomplete tolerance, and 16.2% did not achieve an acceptable tolerance dose. Most of the latter patients had a positive baseline OOFC with low doses of boiled egg. The average number of reactions per treated patient was 5.8, most of them grades 1 and 2 there were no grade 4 reactions.

Conclusions: This home-based oral immunotherapy protocol proved to effectively induce tolerance to hen’s egg in most of the egg-allergic children and its safety profile was acceptable.

Background: In the last two decades milk oral immunotherapy has gained interest as an effective treatment option for milk-allergic patients.

Objectives: To report on the efficacy of a milk oral immunotherapy.

Methods: Children with immunoglobulin E-mediated cow’s milk allergy were included in the protocol. The treatment consisted of an induction phase in which milk doses were increased weekly in the hospital, while the tolerated dose was continued daily at home. The goal was to achieve a minimum milk intake of 200 ml a day. During the maintenance phase, patients ingested at least 200 ml of milk in a single dose every day.

Results: The protocol was applied to 105 milk-allergic children diagnosed by specific IgE to milk and controlled oral food challenge. The mean duration of the induction phase was 19 weeks. Of the 105 subjects, 86 (81.9%) successfully complied with the protocol and 19 (19.1%) failed. Causes of failure were moderate/severe reactions in 12 patients (12.44%) and personal reasons in 7 (6.66%). A total of 182 adverse reactions occurred during the induction phase, most of them mild. Baseline specific IgE to milk and casein were significantly lower (P < 0.05) in the successfully treated group compared to the group in which the treatment failed.

Conclusions: Milk oral immunotherapy is a safe and effective treatment for milk-allergic children, although adverse reactions may occur. Baseline milk and casein-specific IgE may be useful to predict a good response to milk oral immunotherapy.

Background: Neonatal cerebral imaging is a sensitive technique for evaluating brain injury in the neonatal period. When performing computed tomography or magnetic resonance imaging, sedation is needed to prevent motion artifacts. However, general anesthesia in neonates carries significant risks and requires a complex logistic approach that often limits the use of these modalities. The development of infant immobilizers now enables imaging without general anesthesia and significantly increases clinical and research investigational opportunities.

Objectives: To assess the efficacy of the infant immobilizer instead of general anesthesia for infants undergoing imaging.

Methods: The study group comprised all infants born over a 1 year period at Soroka University Medical Center who required imaging such as MRI, CT or bone scans. A MedVac Vacuum Splint infant immobilizer was used in all infants to prevent motion during imaging. The success rate of a single scan and the need for general anesthesia were assessed.  

Results: Forty infants were examined during 1 year. The studies included 15 CT scans, 25 MRIs and 1 bone scan. The infants’ gestational age at birth was 27–40 weeks and the examinations were performed at ages ranging from delivery to 6 months old. All imaging was successful and none of the infants required general anesthesia.

Conclusions: An infant immobilizer should be used for imaging of newborns. Since this method carries a low risk and has a high success rate, general anesthesia in newborns is justified only when this non-invasive procedure fails.
 

Background: The "obesity paradox" is defined as an inverse association of good health, survival and obesity. Usually in healthy persons the more obese you are the more metabolic complications you have; however, thin patients with chronic obstructive pulmonary disease (COPD) have more cardiovascular complications and a higher mortality rate.

Objectives: To explore whether atherosclerosis and peripheral artery disease (PAD) contribute to the higher morbidity and mortality of patients with COPD.

Methods: This prospective study included 87 patients with chronic COPD who were treated in the pulmonary outpatient clinic; all signed a consent form before enrollment. We documented their lung function (FEV1%), body mass index (BMI) and ankle brachial index (ABI). The primary endpoints were to find an association between atherosclerosis and BMI in patients with COPD, and between atherosclerosis and severity of lung disease.

Results: Average ABI[1] was 1.01 ± 0.20, BMI[2] was 29.33 ± 7.48 kg/m2, and the abdominal circumference was 107.34 ± 18.87 cm. A positive correlation was found between BMI and ABI (P = 0.001) and between abdominal circumference and ABI (P = 0.000). Patients with peripheral artery disease were older (73.6 ± 11.5 vs. 68.1 ± 11.6 years old, P = 0.04), were thinner (average BMI 25.5 ± 6.2 vs. 31.06 ± 7.3, P = 0.001), and had a lower abdominal circumference (97.7 ± 18.3 vs. 111.7 ± 17.5 cm, P = 0.001). No such difference was observed for years of smoking. Male PAD patients with COPD had a lower BMI (25.2 ± 5.6 vs. 29.9 ± 7.4, P = 0.016), and their abdominal circumference was smaller (96.1 ± 18.0 vs. 110.2 ± 16.5 cm, P = 0.004). Female PAD patients with COPD had a lower BMI (26.3 ± 8.2 vs. 33.1 ± 7.0, P = 0.045), but their abdominal circumference was not different from females without PAD (102.0 ± 19.7 vs. 114.0 ± 19.4 cm, P = 0.162). Patients with PAD had a worse lung disease (FEV1% 34 ± 8% vs. 45 ± 16%, P = 0.01). During the 1 year of follow-up five patients died: two PAD patients due to acute myocardial infarction and three non-PAD patients died from pulmonary insufficiency (two patients) and pulmonary emboli (one patient).

Discussion: We found that COPD patients with PAD were older and thinner and had a lower abdominal circumference and a more progressive lung disease. Extensive atherosclerosis in patients with COPD may partly explain the “obesity paradox” observed in patients with COPD.

Since the Surviving Sepsis Campaign Guideline (SSG) was published in 2004, critical care physicians can readily access the evidence and current recommendations regarding management of patients with severe sepsis and septic shock. However, several issues including a potential conflict of interest in developing the guidelines were disclosed. There have also been dramatic changes in the management of sepsis, supported by high levels of evidence. SSG[1] 2008 was developed to update the evidence using a new grading system. We reviewed select topics, routinely addressed by intensivists in the surgical intensive care unit, that have changed between SSG 2004 and SSG 2008: namely, glucose control, and administration of steroids, recombinant human activated protein C (rhAPC) and total parenteral nutrition.

Background: In the past, carotid endarterectomy (CEA) was the only modality for invasive intervention in cases of carotid stenosis. Due to improvements in endovascular techniques (stenting), there is a growing debate regarding the preferred procedure for carotid intervention.

Objectives: To compare the 30 day complication rate after CEA and carotid angioplasty and stenting (CAS) in a tertiary medical center in Israel between the years 2008 and 2010.

Methods: We reviewed the medical charts of all the patients who underwent either CEA or CAS of the internal carotid artery due to symptomatic and asymptomatic stenosis during the period 2008–2010 (total of 128 patients).

Results: There was no difference between the groups in the rate of severe complications in the peri-procedural period. Mild complications were non-significantly more common in the CEA group (17%) compared to the CAS group (7.1%).

Conclusions: There was no significant difference in the mild and severe complications rate between CEA and CAS in the peri-procedural period.

Background: Gastric stump cancer is often described as a tumor with a poor prognosis and low resectability rates.

Objectives: To compare the pathological characteristics of gastric stump cancer patients with those of patients with proximal gastric cancer.

Methods: This retrospective study was based on the demographic and pathological data of patients diagnosed with gastric cancer and treated at Assaf Harofeh Medical Center during an 11 year period. The patients were divided into two groups: those undergoing proximal gastrectomy for proximal gastric cancer and those undergoing total gastrectomy for gastric stump cancer.

Results: Patients with gastric stump cancer were predominantly male, older (P = 0.202, not significant), and had a lower T stage with less signet-ring type histology, fewer harvested and fewer involved lymph nodes (P = 0.03, statistically significant) and less vascular/lymphatic involvement than patients with proximal gastric cancer.

Conclusions: The lower incidence of involved lymph nodes and lymphovascular invasion in gastric stump cancer as compared to proximal gastric cancer in this study may imply that the prognosis of gastric stump cancer may be better than that of proximal gastric cancer. However, to verify this assumption a study comparing patient survival is required.
