Background: We recently published preliminary evidence on the effectiveness of hypertonic saline in infants with viral bronchiolitis.

Objective: To further establish the efficacy of nebulized hypertonic saline in these infants

Methods: In a continuing, second-year randomized, double-blind controlled trial, an additional 41 infants (age 2.6 ± 1 months) hospitalized with viral bronchiolitis were recruited during the winter of 2001–2002. The infants received inhalation of 1.5 mg epinephrine dissolved either in 4 ml normal (0.9%) saline (Group I, n=20) or 4 ml hypertonic (3%) saline (Group II, n=22). The therapy was repeated three times daily until discharge. Pooling our 2 years of experience (2000–2002), a total of 93 hospitalized infants with viral bronchiolitis were recruited; 45 were assigned to Group I and 48 to Group II.

Results: The clinical scores at baseline were 7.6 ± 0.7 for Group I vs. 7.4 ± 1.3 for Group II (P = NS). However, the clinical scores at days 1 and 2 after inhalation differed significantly between the two groups, invariably favoring Group II: 7 ± 1 vs. 6.25 ± 1.1 (P < 0.05), 6.45 ± 1 vs. 5.35 ± 1.35 (P < 0.05), respectively. Adding aerosolized 3% saline to 1.5 mg epinephrine reduced the hospitalization stay from 3.5 ± 1.7 days in Group I to 2.6 ± 1.4 in Group II (P < 0.05). The pooled data of both years revealed that adding 3% saline to the inhalation mixture decreased hospitalization stay from 3.6 ± 1.6 to 2.8 ± 1.3 days (P < 0.05).
Conclusions: This second-year experience and our 2 year pooled data analysis strengthen the evidence that the combination of 3% saline/1.5 mg epinephrine benefits hospitalized infants with viral bronchiolitis

Background: Peritoneal dialysis is a widely accepted route for renal replacement. With the advent of endoscopy, many surgical techniques for the prevention of catheter failure have been proposed.

Objectives: To evaluate the outcomes of patients undergoing laparoscopic Tenckhoff catheter implantation, using the pelvic fixation technique.

Methods: Data analysis was retrospective. All procedures were performed under general anesthesia. A double-cuffed catheter was inserted using two 5 mm trocars and one 10 mm trocar, fixing its internal tip to the dome of the bladder and its inner cuff to the fascia. Catheter failure was defined as persistent peritonitis/exit-site/tunnel infection, severe dialysate leak, migration or outflow obstruction.

Results: LTCI[1] was performed in 34 patients. Mean patient age was 65 ± 17 years. In 12 of the 34 patients the indication for LTCI was end-stage renal failure combined with NYHA class IV congestive heart failure. Operative time was 35 ± 15 minutes. A previous laparotomy was performed in 9 patients. Hospital stay was 1.5 ± 0.6 days. The first continuous ambulatory peritoneal dialysis was performed after 20 ± 12 days. Median follow-up time was 13 months. There were several complications, including 5 (14%) exit-site/tunnel infections, 27 episodes (0.05 per patient-month) of bacterial peritonitis, 3 (9%) incisional hernias, 1 case of fatal intraabdominal bleeding, 2 (5.8%) catheter migrations (functionally significant), and 10 (30%) cases of catheter plugging, 8 of which were treated successfully by instillation of urokinase and 2 surgically. A complication-mandated surgery was performed in 8 patients (23.5%). The 1 year failure-free rate of the catheter was 80.8%. One fatal intraabdominal bleeding was recorded.
Conclusions: LTCI is safe, obviating the need for laparotomy in high risk patients. Catheter fixation to the bladder may prevent common mechanical failures

Background: The suspicion of child abuse and neglect may arise from manifestations such as physical or psychosomatic symptoms, eating disorders, suicidal behavior, impaired parental functioning, etc. Thus the arrival of an abused or neglected child at the hospital provides an opportunity for detecting the problem and beginning a process of change. Optimal utilization of this potential depends on the awareness, diagnostic ability and cooperation of the staff.

Objectives: To assess knowledge about hospital policy, attitudes and actual behavior of hospital staff in cases of SCAN[1].

Methods: The questionnaire was adapted and distributed to a convenience sample of personnel at a children’s hospital. The questionnaire included items on knowledge of hospital policy regarding SCAN, attitudes towards inquiring about cases that appear suspicious, and behaviors in cases in which the respondent was involved. The comparison of responses to specific questions and among members of different professions was analyzed by chi-square test.

Results: Eighty-two staff members completed the questionnaires. Most of the respondents were aware of hospital policy regarding suspected abuse (86.6%), with fewer regarding suspected neglect (77.2%). Physicians were the least aware of these policies, as compared to medical students, nurses and social workers. Although most considered the issue of SCAN a responsibility of members of their own profession, 35.4% considered it primarily the responsibility of the welfare or judicial systems. Over 40% felt uncomfortable discussing suspicions with the child and nearly half felt uncomfortable discussing them with parents. The most often reported reason for this was the sense that they lacked skills or training for dealing with the issue. Despite this, when asked about actual behavior, 94.7% responded that they do try to clarify the circumstances related to the suspicious symptoms. Respondents were more likely to contact the hospital social worker than community resources (91.5% vs. 47.2%).

Conclusions: The findings highlight the need to encourage awareness, discourse and training of medical personnel about issues related to SCAN in order to maximize their potential contribution to identifying children at risk.

The role of skin substitutes in burn surgery and in the treatment of chronic wounds is constantly evolving. New products are regularly being developed and approved for clinical use. Studies on existing products demonstrate their effectiveness in different clinical scenarios. However, cost-related concerns, inadequate physician education, and the drawbacks that still accompany every skin substitute have resulted in limited application of these modalities. Today, burn surgeons still rely mostly on old-fashioned skin grafts. Only a few burn centers in the world actually use some of these products in their routine treatment of wounds. This review provides an up-to-date overview of the latest developments in the field of skin substitutes. We examine the major commercially available skin substitute products and their performance, and briefly review the technologies and products that are under development but have not yet become widely available.

Endometrial polyps are a frequent finding in infertile patients. Little is known about the true prevalence of polyps in infertile patients. It is unproved whether polyps are causative of infertility, or whether surgical polypectomy by hysteroscopy improves the likelihood of successful conception. This article reviews endometrial polyps in reproductive-age fertile and infertile women.

Background: Men and postmenopausal women with iron deficiency anemia are routinely evaluated to exclude a gastrointestinal source of suspected internal bleeding. Iron deficiency anemia in premenopausal women is often treated with simple iron replacement, under the assumption that the condition is due to excessive menstrual blood loss.

Objectives: To determine the yield of endoscopy evaluations in premenopausal women with iron deficiency anemia.

Methods: Upper and lower gastrointestinal endoscopic examinations were conducted in 45 premenopausal women with iron deficiency anemia not related to gynecologic or nutritional causes.

Results: Forty-three of the 45 women fulfilled the entry criteria and were enrolled. Their mean age was 35 ± 15 years and their mean hemoglobin level 9.3 ± 2.3 g/dl. Twenty‑eight upper gastrointestinal lesions were demonstrated in 24 of the 43 patients (55.8%): erosive gastritis in 12 (27.9%), erosive duodenitis in 4 (9.3%), erosive esophagitis in 3 (7.0%), hiatus hernia (with Cameron lesions) in 3 (7.0%), active duodenal ulcer in 1 (2.3%) and hyperplastic polyp (10 mm) in 1 (2.3%). Five lower gastrointestinal lesions were detected in 5 patients (16.3%): 2 (4.6%) had adenocarcinoma of the right colon, 2 (4.6%) had pedunculate adenomatous polyp > 10 mm, and 1 (2.3%) had segmental colitis (Crohn's disease). One patient (2.3%) had pathologic findings in both the upper and lower gastrointestinal tracts.

Conclusions: Our findings of a gastrointestinal source of chronic blood loss in 28 of 43 premenopausal women with iron deficiency anemia (65.1%) suggest that this population will benefit from bi‑directional endoscopic evaluations of the gastrointestinal tract.

Background: Persistent creatine kinase elevation is occasionally encountered in subjects without any clinical manifestation of a neuromuscular disorder or any condition known to be associated with increased serum CK[1] levels. It is still unresolved whether extensive investigations and specifically a muscle biopsy should be performed in clinically normal individuals with elevated CK levels.

Objective: To study the muscle pathology of patients with asymptomatic or minimally symptomatic hyperCKemia.

Methods: The clinical and laboratory data of patients with persistent hyperCKemia and normal neurologic examination were reviewed and their muscle biopsies evaluated.

Results: The study group included 40 patients aged 7–67 years; the male to female ratio was 3:1. Nineteen patients were completely asymptomatic, 20 had mild non-specific myalgia, and 1 had muscle cramps. Electromyography was performed in 27 patients and showed myopathic changes in 7 (26%). Abnormal muscle biopsy findings (e.g., increased variation in fiber size, increased number of central nuclei and occasional degenerating fibers) were detected in 22 of the 40 patients (55%). No fat or glycogen accumulation was detected. Immunohistochemistry demonstrated abnormal dystrophin staining in 3 patients (8%), resembling the pathologic changes of Becker muscular dystrophy. No abnormal findings were detected on immunohistochemical staining for merosin, dysferlin, caveolin 3, or alpha and gamma sarcoglycans. The EMG[2] findings did not correlate with the pathologic findings.

Conclusions: Abnormal muscle biopsies were found in 55% of patients with asymptomatic or minimally symptomatic hyperCKemia. Specific diagnosis of muscular dystrophy, however, was possible in only 8% of the patients.

Three decades have elapsed since the inception of Level I trauma centers as the final link in the trauma system "chain of survival".

Chronic periaortitis is a rare disease affecting the abdominal aorta, usually below the level of the renal arteries.

Background: There are no national data on the burden and management of acute cerebrovascular disease in Israel.

Objectives: To delineate the burden, characteristics, management and outcomes of hospitalized patients with acute cerebrovascular disease in Israel, and to examine adherence to current guidelines.

Methods: We prospectively performed a national survey in all 28 hospitals in Israel admitting patients with acute cerebrovascular events (stroke or transient ischemic attacks) during February and March 2004.

Results: During the survey period 2,174 patients were admitted with acute cerebrovascular disease (mean age 71 ± 13 years, 47% women; 89% ischemic stroke or TIA[1], 7% intracerebral hemorrhage and 4% undetermined stroke). Sixty-two percent of patients were admitted to departments of Medicine and a third to Neurology, of which only 7% were admitted to departments with a designated stroke unit. Head computed tomography was performed during hospitalization in 93% of patients. The overall rate of urgent thrombolytic therapy for acute ischemic stroke was 0.5%. Among patients with ischemic stroke or TIA, 94% were prescribed an antithrombotic medication at hospital discharge, and among those with atrial fibrillation about half were prescribed warfarin. Carotid duplex was performed in 30% and any vascular imaging study in 36% of patients with ischemic events. The mean length of hospital stay was 12 ± 27 days for ICH[2] and 8 ± 11 days for ischemic stroke. Among patients with ICH, 28% died and 66% died or had severe disability at hospital discharge, and for ischemic stroke the corresponding rates were 7% and 41% respectively. Mortality rates within 3 months were 34% for ICH and 14% for ischemic stroke.

Conclusions: This national survey demonstrates the high burden of acute stroke in Israel and reveals discordance between existing guidelines and current practice. The findings highlight important areas for which reorganization is imperative for patients afflicted with acute stroke.

Background: During the last decade, Israel, a country with low tuberculosis rates, absorbed some 900,000 new immigrants from TB[1]-endemic countries.

Objectives: To analyze the specific impact of our screening procedures on active TB among children in Israel.

Methods: We conducted a retrospective analysis of epidemiologic and clinical data of all children (aged 0–17) with TB notified to the Ministry of Health between 1990 and 1999.

Results: There were 479 children with TB (male/female ratio 1.36). Most cases (81.8%) were foreign born, predominantly (88.2%) immigrants from Ethiopia and, therefore, huge differences existed in TB incidence rates according to countries of origin. Some 80% were diagnosed within 3 years of arrival, mainly due to active case-finding. Pulmonary TB, with infiltrates on chest X-ray, was found in 49.5%. Extra-pulmonary TB sites were: intra-thoracic lymphadenitis (31.1%), extra-thoracic lymphadenitis (12.5%), bones (3.6%), pleura (1.3%), meninges (1%), and others (1%). Seventy percent had a tuberculin skin test reaction ≥10 mm in size. Two (non-immigrant) children died of TB meningitis.

Conclusions: Most of the pediatric TB cases occurred in recent immigrants and were diagnosed within 3 years of immigration. These data support our policy of active case-finding among new immigrants from Ethiopia and extensive contact evaluation for all TB cases.
