Objectives: To investigate these injuries with respect to type, incidence and modes of prevention.

Methods: A retrospective study of medical records was performed for all patients admitted to Assaf Harofeh Medical Center due to horse-related injury between January 1984 and December 2008. A telephone questionnaire was used to complete the data.

Results: Eighty-nine subjects (267 injuries) were included in the study. Most of them were not professional horse riders or horse handlers. Helmet use was reported in only 28% of the participants. The number of subjects with horse-related injuries and the percentage of pediatric involvement increased during the study period. Falling from a horse was the most frequent cause of injury (60.67%), followed by being kicked (13.4%). Head and extremities were the most affected areas. On admission, 33.7% had a potential severe injury score. Forty-two participants (47%) had underlying fractures, mostly in the upper extremities. In the pediatric population, 16.2% (vs. 0% adults) rode horses for therapeutic reasons. Seventeen subjects reported having long-term consequences.

Conclusions: The findings are similar to those described in other parts of the world. Horseback riding-related injuries are increasing, which emphasizes the need for safety education programs in Israel.

Suicide is universal within the range of human behaviors and is not necessarily related to psychiatric morbidity, though it is considerably more prevalent among psychiatric patients. Considering the limitations of medical knowledge, psychiatrists cope with an unfounded and almost mythical perception of their ability to predict and prevent suicide. We set out to compose a position paper for the Israel Psychiatric Association (IPA) that clarifies expectations from psychiatrists when treating suicidal patients, focusing on risk assessment and boundaries of responsibility, in the era of defensive medicine. The final draft of the position paper was by consensus. The IPA Position Paper established the first standard of care concerning expectations from psychiatrists in Israel with regard to knowledge-based assessment of suicide risk, elucidation of the therapist's responsibility to the suicidal psychotic patient (defined by law) compared to patients with preserved reality testing, capacity for choice, and responsibility for their actions. Therapists will be judged for professional performance rather than outcomes and wisdom of hindsight. This paper may provide support for psychiatrists who, with clinical professionalism rather than extenuating considerations of defensive medicine, strive to save the lives of suicidal patients.
 

Background: Seborrheic dermatitis is a common chronic disease. Malassezia yeasts have been implicated in the pathogenesis of this disease. Antifungal agents are known to be effective in the treatment of Malassezia yeast infections.

Objectives To evaluate the efficacy of itraconazole in the treatment of mild to severe facial seborrheic dermatitis.

Methods: Sixty patients with moderate to severe seborrheic dermatitis were evaluated in an open non-comparative study. Patients were treated with oral itraconazole, initially 200 mg/day for a week, followed by a maintenance therapy of a single dose of 200 mg every 2 weeks. Four clinical parameters (erythema, scaling, burning, itching) were assessed using a 0–3 score. Mycological evaluation determined the presence of Malassezia spores in the scales using a direct smear.

Results: At the end of the initial treatment significant improvement was reported in three clinical parameters: erythema, scaling, itching. Maintenance therapy led to only slight further improvement. Burning sensation was only mildly improved during the treatment. The quantity of Malassezia spores present in the direct smear decreased throughout the treatment period. No blood test abnormalities were found during the treatment.

Conclusions: In this study initial treatment with itraconazole was beneficial in patients with moderate to severe seborrheic dermatitis.

Background: Iron deficiency is the most common single cause of anemia worldwide. Treatment consists of improved nutrition along with oral, intramuscular or intravenous iron administration.

Objectives: To describe the efficacy and adverse effects of intravenous iron sucrose therapy in a group of children with iron deficiency anemia who did not respond to oral iron therapy.

Methods: We conducted a prospective investigation of 45 children, aged 11 months to 16 years, whose oral iron therapy had failed. The children attended the Pediatric Ambulatory Care Unit where they received intravenous iron sucrose infusion.

Results: Forty-four of the 45 patients were non-compliant. Nine had Helicobacter pylori gastritis and 16 patients suffered from intestinal malabsorption from different causes. Before treatment, the blood mean hemoglobin concentration was 7.43 g/dl (range 5–10.1 g/dl). Fourteen days after treatment the mean hemoglobin concentration increased to 9.27 g/dl (SD 1.23) and 6 months later to 12.40 g/dl (SD 1.28). One patient demonstrated a severe side effect with temporary and reversible reduced blood pressure during treatment.

Conclusions: These preliminary data suggest that administration of intravenous iron in pediatric patients is well tolerated and has a good clinical result, with minimal adverse reactions.

Background: Interleukin-8 is a prototypical inflammatory chemokine that induces leukocyte migration to inflammatory sites. Leukocyte recruitment in response to gradients of this chemokine is attenuated at advanced stages of inflammation to prevent damage to surrounding healthy tissues. Our published studies suggest that over-phosphorylation of focal adhesion kinase in migration-desensitizing conditions is involved in cessation of cell motility. This over-phosphorylation of FAK[1] was induced by IL-8[2] only when the receptor transmitting the chemokine signals was CXCR2, and not CXCR1, indicating that the two IL-8 receptors diverge in their signaling properties.

Objectives: To analyze the regulation of FAK in CXCR2-expressing hematopoietic cells under conditions of migratory desensitization, focusing on the roles played by adhesion-related components in this process.

Methods: Under conditions of migratory desensitization, we determined IL-8-induced cell spreading and FAK localization following disruption of actin filaments, and evaluated the role of integrins in FAK phosphorylation.

Results: The disturbance of intact activity of actin filaments resulted in inhibition of cell spreading and modification of FAK intracellular localization upon IL-8 stimulation. Also, adhesion-dependent pre-stimulation of integrins was required for IL-8-induced FAK phosphorylation.
Conclusions: Intact actin filaments and integrins are required for optimal IL-8-induced FAK phosphorylation in conditions of migratory desensitization. These observations suggest that lack of adequate activity/regulation of adhesion-related components may give rise to FAK activities that are not appropriately controlled, possibly leading to pathological conditions that are associated with perturbed leukocyte migration phenotypes

Objectives: To assess the risk of microvascular complications associated with the metabolic syndrome in diabetes subjects.

Methods: The study group comprised 415 diabetic subjects attending a primary care clinic. The prevalence of microvascular complications was compared between 270 diabetic subjects with metabolic syndrome (NCEP-III criteria) and 145 diabetic patients without.

Results: We found that as a group, diabetic subjects with metabolic syndrome had significantly higher frequency of microvascular-related complications than diabetic subjects without the syndrome (46.6% and 26.8% respectively, P = 0.0005). These include microalbuminuria (41.5% vs. 23.9%, P = 0.013), neuropathy (10.4% vs. 7.5%, P = 0.38), retinopathy (9.6% vs. 4.1%, P = 0.046) and leg ulcers (7.9% vs. 2.8%, P = 0.044). After adjustment for age, gender, glycemic control, disease duration, lipid profile and blood pressure, metabolic syndrome was associated with a significantly higher risk of microvascular complications: odds ratio (95% confidence interval) for nephropathy 2.27 (1.53–3.34), neuropathy 1.77 (0.79–4.0), retinopathy 3.42 (1.2–9.87), and leg ulcers 3.57 (1.08–11.95).

Conclusions: In addition to hyperglycemia and disease duration, the metabolic syndrome is a significant risk factor for the development of microvascular complications in diabetic subjects.

Background: Analysis of the trends in psychiatric admissions and discharges is necessary to correctly plan and distribute resources, especially given the current international climate of “deinstitutionalization." Israel, too, is implementing “reform” in the national psychiatric system – to transfer psychiatric treatment from a hospital to a community setting

Objectives: To analyze admission and discharge patterns, explore trends in psychiatric hospital length of stay, and compare these characteristics between first-episode and chronic patients, between children, youth and adults, and between hospitals.

Methods: All admissions and discharges from inpatient psychiatric wards between the years 2000 and 2004 were analyzed and characterized according to age, length of hospitalization, legal status, and nature of admitting institution (state hospital, health fund, general hospital).

Results: Mean length of stay in adults decreased during the 5 year study period, from 37.6 days in 2000 to 36.4 days in 2004. In years with higher admissions, hospital stay was shorter (P < 0.05). Length of stay in psychiatric wards in general hospitals was shorter than in state hospitals (P < 0.001). In contrast to adults and children, length of stay among adolescents showed a gradual increase (P < 0.05). Involuntary hospitalization comprised 25.3% of all admissions, and 16.8% of discharged patients were readmitted within 30 days. A dramatic decrease (24.3%) in the number of chronic hospitalizations was noted.

Conclusions: Various factors may account for these developments. Protracted hospitalizations may be reduced through changes in various aspects of treatment planning and psychiatric care continuum. The decrease in number of admissions, length of stay and number of chronically admitted patients remains in line with international practices. Particular attention needs to be devoted to planning and funding so that availability of community services matches reduction in psychiatric hospitalization.
 

Objectives: To examine the effect of postoperative loco-regional radiotherapy on local and regional recurrence and survival in breast cancer patients with four or more involved lymph nodes or extracapsular tumor extension.

Methods: This controlled clinical trial included 258 breast cancer patients with four or more involved nodes or ECE[1]. Eighty-nine patients in the control group had modified radical mastectomy and received adjuvant chemotherapy with melphalan and 5FU, but no radiation therapy. The 169 patients in the study group (87 with MRM[2] and 82 with lumpectomy and axillary dissection) received various adjuvant chemotherapy regimes and radiation therapy to the chest wall/breast, supraclavicular region and full axilla.

Results: With an average follow-up of more than 5 years, loco-regional radiation significantly reduced local and regional disease recurrence. The median disease-free survival was significantly longer in radiated patients (59.2 months and 63.3 months in the MRM and L+AXLND[3] groups, respectively, vs. 28.4 months in the control group; P < 0.01). There was no difference in the rate of systemic recurrence and overall survival. The median overall survival was 71.2 and 67.5 months in the study groups (MRM and L+AXLND, respectively) and 70.5 months in the control group (P = 0.856).

Conclusions: Radiotherapy to the breast/chest wall and to the draining lymphatics, in addition to surgery and adjuvant therapy, significantly reduced the risk of local and regional recurrence in high risk breast cancer patients with four or more involved lymph nodes or ECE.

Background: Contralateral exploration of the groin has been common practice among pediatric surgeons for nearly 50 years, based on the high incidence of patent processus vaginalis on the contralateral side with the potential for the subsequent development of a hernia.

Objectives: To evaluate transinguinal laparoscopic examination of the contralateral side during repair of inguinal hernia in children in order to reach a decision regarding exploration of the contralateral side.

Methods: Over a of 21 month period 124 children with unilateral inguinal hernia underwent laparoscopic evaluation of the contralateral groin. The operations were performed under general anesthesia as ambulatory procedures.

Results: Transinguinal contralateral laparoscopic exploration was positive (patent processus vaginalis) in 26 children (21%) and negative (closed processus vaginalis) in 88 (71%). Failure to introduce the telescope occurred in 10 patients (8%) due to a friable or narrow hernia sac. Twenty-five children below 2 years of age were spared exploration of the contralateral side as a result of the negative laparoscopic examination. On the other hand, 15 children aged 2–17 had their contralateral groin explored because of a positive finding at laparoscopy.

Conclusions: Transinguinal laparoscopic examination of the contralateral side during repair of inguinal hernia in children is a simple, safe and quick method to avoid systematic bilateral explorations and should be part of every pediatric surgeon's experience.

Background: Pseudomembranous colitis is a well-recognized cause of diarrhea in patients receiving antibiotics and has significant consequences in terms of morbidity, mortality and cost. Clostridium difficile infection is the single most important infectious cause of PMC[1]. PMC is frequently nosocomial, with an increased risk of spread among institutionalized patients, both in hospitals and nursing homes.

Objective: To investigate the demographic, clinical and laboratory characteristics of PMC patients in an Israeli elderly population.

Methods: We studied 72 hospitalized patients with endoscopically proven PMC. The medical records of all patients including clinical history and laboratory data were reviewed, such as: age, pre-hospitalization status (dependency or not, in the community as compared to the nursing home), background medical history, presenting symptoms, antibiotic history, physical examination on admission, hematologic and biochemical parameters, treatment, duration of hospitalization, complications, mortality and recurrence of disease.

Results: Of the 72 patients (34 males and 38 females, mean age 77 years) 47% were nursing home residents. Pre-hospitalization antibiotic treatment was given to 91.4% for infections of the upper respiratory tract (45%) and urinary tract (45%). The most common antibiotics were cephalosporin (64%), penicillins (42%) and quinolones (28%). Sixty-four percent of the patients were treated with more than one antibiotic, 26% of patients received anti-acid therapy and 36% had been fed with a nasogastric tube. On admission, leukocytosis was found in 79% of patients, >20,000/mm³ in half of them; 60% were anemic, 60% had elevated erythrocyte sedimentation rate, and 78% had hypoalbuminemia. Treatment consisted of metronidazole (41%) or a combination of metronidazole and vancomycin (56%). Overall, 31% of patients recovered without complications, 29% died within 30 days of hospitalization, and 24% were re-hospitalized due to recurrence of PMC.

Conclusion: The most common antibiotics implicated in PMC are cephalosporin, penicillins and quinolones. The disease is associated with high mortality and recurrence rates.
