Background: Alternatives to cow’s milk and soy milk are often necessary for children with food allergies. Although hydrolyzed and elemental formulas are appropriate replacements, other milk products such as rice and almond milk are insufficient protein sources for children under 2 years of age. A chart review on three patients treated for protein malnutrition in association with multiple diagnosed food allergies that resulted in refractory eczema revealed adverse outcomes that resulted from elimination diets. The use of rice milk resulted in hypoalbuminemia and poor weight gain in all cases, and multiple secondary infections in one patient. These cases illustrate the need for careful nutritional guidance in the management of food allergy, as well as the importance of cautious use and interpretation of testing for food allergies in the absence of a clear clinical history of reaction.

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.

Physicians have a great interest in discussions of life and its origin, including life's persistence through successive cycles of self-replication under extreme climatic and man-made trials and tribulations. We review here the fundamental processes that, contrary to human intuition, life may be seen heuristically as an ab initio, fundamental process at the interface between the complementary forces of gravitation and quantum mechanics. Analogies can predict applications of quantum mechanics to human physiology in addition to that already being applied, in particular to aspects of brain activity and pathology. This potential will also extend eventually to, for example, autoimmunity, genetic selection and aging. We present these thoughts in perspective against a background of changes in some physical fundamentals of science, from the earlier times of the natural philosophers of medicine to the technological medical gurus of today. Despite the enormous advances in medical science, including integration of technological changes that have led to the newer clinical applications of magnetic resonance imaging and PET scans and of computerized drug design, there is an intellectual vacuum as to how the physics of matter became translated to the biology of life. The essence and future of medicine continue to lie in cautious, systematic and ethically bound practice and scientific research based on fundamental physical laws accepted as true until proven false.
 

Background: Comorbid depression may play an important role in non-compliance with medical treatment among patients with chronic illnesses. Glaucoma is a potentially blinding chronic disease requiring life-long commitment to medical therapy. Patient's failure to adhere to anti-glaucoma treatment may lead to disease progression and visual loss.

Objectives: To assess the prevalence of depressive symptoms in glaucoma patients and the association between these symptoms and non-compliance with anti-glaucoma therapy.

Methods: This was a cross-sectional observational study. Compliance with pharmacotherapy was assessed with the Morisky Medication Adherence questionnaire (eight items). Screening for depression was performed by means of the CES-D scale (Center for Epidemiologic Studies Depression scale). The association between depression and compliance rates was analyzed.

Results: The study group comprised 76 glaucoma patients; 19.7% of the subjects were classified as "non-compliant" (Morisky cutoff < 10) and 21.1% suffered from depression (CES-D cutoff ≥ 16). We found a similar level of non-compliance when comparing depressed with non-depressed glaucoma patients. However, a significant correlation was observed between the level of depression and the level of non-compliance (P = 0.04).

Conclusions: Our study revealed a similar rate of depression in glaucoma patients and the general Israeli population. The presence of depression was not associated with the presence of non-compliance, yet the level of depression was associated with the level of non-compliance.

Background: Sudden death in athletes can occur during sport activities and is presumably related to ventricular arrhythmias. There are no guidelines concerning athletes who develop ventricular arrhythmias during an exercise test. It is unclear whether they should be allowed to continue with their competitive activity or not.

Objectives: To investigate the long-term follow-up of athletes with ventricular arrhythmias during an exercise test.

Methods: From a database of 56,462 athletes we identified 192 athletes, less than 35 years old, who had ventricular arrhythmias during an exercise test. Ninety athletes had ≥ 3 ventricular premature beats (group A) and 102 athletes had ventricular couplets or non-sustained ventricular tachycardia during an exercise test (group B). A control group of 92 athletes without ventricular arrhythmias was randomly selected from the database (group C).

Results: All athletes, except one who died from a dilated cardiomyopathy, were alive during a follow-up period of 70 ± 25 months. An abnormal echocardiogram was obtained in seven athletes from group A (10%), four from group B (5%), and one from group C (3%) (not significant). An abnormal echocardiogram was more likely to be present in competitive athletes (P = 0.001) and in female athletes (P = 0.01).

Conclusions: Our results showed that ventricular arrhythmias during exercise are more commonly associated with cardiovascular abnormalities in young competitive athletes and in female athletes. When present, they necessitate a thorough investigation and follow-up.
 

Background: The compliance of hospital staff with guidelines for the active surveillance of methicillin-resistant Staphylococcus aureus (MRSA) in Israel has not been determined.

Objectives: To evaluate the compliance of hospital staff with guidelines for the active surveillance of MRSA and assess its impact on the incidence of nosocomial MRSA bacteremia.

Methods: We assessed compliance with MRSA surveillance guidelines by assessing adherence to the screening protocol and reviewing medical and nursing charts of patients colonized with MRSA, and observed hand hygiene opportunities among health care workers and colonized patients. Rates of nosocomial MRSA bacteremia and of adherence with hand hygiene among overall hospital staff were obtained from archived data for the period 2001–2010.

Results: Only 32.4% of eligible patients were screened for MRSA carriage on admission, and 69.9% of MRSA carriers did not receive any eradication treatment. The mean rate of adherence to glove use among nurses and doctors was 69% and 31% respectively (P < 0.01) and to hand hygiene 59% and 41% respectively (P < 0.01). The hospital overall rate of adherence to hand hygiene increased from 42.3% in 2005 to 68.1% in 2010. Rates of nosocomial MRSA bacteremia decreased by 79.2%, from 0.48 (in 2001) to 0.1 (in 2010) per 1000 admissions (P < 0.001).

Conclusions: The compliance of medical and nursing staff with guidelines for active MRSA surveillance was poor. The encouraging increase in adherence to hand hygiene and concomitant decrease in nosocomial MRSA bacteremia is gratifying. The deficiencies in compliance with MRSA infection control policy warrant an adjusted strategy based on the hospital resources.

Background: Adjuvant/neoadjuvant chemotherapy in breast cancer patients may be associated with amenorrhea and a marked reduction in ovarian reserve.

Objectives: To assess the use of letrozole with follicle-stimulating hormone (FSH) in gonadotropin-releasing hormone (GnRH) analogue protocols, based on reported attempts to avoid the estradiol (E2) increase during controlled ovarian hyperstimulation for embryo cryopreservation in breast cancer patients using a combination of low dose FSH and aromatase inhibitor (letrozole) in a GnRH-antagonist protocol.

Methods: Twenty-four breast cancer patients were treated with recombinant FSH (150–450 U/day) and letrozole (5 mg/day) in a long GnRH-agonist (n=7) or GnRH-antagonist (n=17) protocol. After oocyte retrieval, insemination and/or intracytoplasmic sperm injection was performed. The embryos were frozen.

Results: The average interval from surgery to oocyte retrieval was 40 days. Average duration of treatment was 9.6 days and mean peak E2 level 1342 ± 1091 pmol/L, yielding 16.0 ± 16.3 oocytes (range 0–82). Mean fertilization rate was 69.5 ± 20.4% and mean number of embryos cryopreserved 10.3 ± 9.3. More oocytes were retrieved with the long GnRH protocol, but the difference was not statistically significant (24.8 ± 24.6 vs. 12.0 ± 8.8 pmol/L, P = 0.07).

Conclusions: As previously reported, ovarian stimulation with letrozole and FSH, in both the long GnRH-agonist and GnRH-antagonist protocols, is apparently effective in breast cancer patients and spares them exposure to high E2 levels.
 

Background: Intraarticular injections for the local treatment of osteoarthritis are widely used in the office or hospital setting. Septic arthritis is a potential catastrophic complication of intraarticular injection, as bacterial arthritis of any cause is associated with up to 15% mortality and residual impairment of joint function in up to 50% of survivors. There is lack of evidence regarding the precautions that should be taken to avoid such a complication, as well as how often it is encountered.

Objectives: To report our experience with the clinical presentation, diagnosis and treatment of knee septic arthritis following intraarticular injections. 

Methods: We followed six patients who were admitted to the hospital and underwent surgery for the treatment of pyogenic arthritis following injection to the knee joint in outpatient clinics.

Results: All but one patient were over 70 years old with comorbidities. Three patients were injected with steroid preparations and three with hyaluronic acid several days before admission. In all six patients the infection was treated surgically and three of them had undergone more than one operation during their hospitalization. Four of the six patients were treated by means of an open arthrotomy and synovectomy, and the other two were treated successfully with arthroscopic lavage and synovectomy. One patient underwent an above-knee amputation due to septic shock and died after several days.

Conclusions: Despite the rarity of this complication, surgeons must be aware of the possibility of pyogenic arthritis when administering injections, especially in elderly patients with serious underlying medical conditions.
