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.

Background: Sentinel lymph node mapping is the standard of care for patients with malignant melanoma and breast cancer. Recently, SLN[1] mapping was introduced to the field of gastric cancer.

Objectives: To evaluate SLN mapping in patients with gastric cancer.

Methods: In 43 patients with gastric cancer, open intraoperative subserosal dye injection in four opposing peritumoral points was used. Ten minutes following dye injection, stained LNs were located, marked and examined postoperatively from the surgical specimen.

Results: SLN mapping was performed in 43 with gastric cancer; 782 lymph nodes were harvested and evaluated. SLNs were stained in 34 of the patients (79.1%) with a mean of 2.85 SLNs per patient. The false negative rate was 20.9%, the positive predictive value 100%, the negative predictive value 78.6% and the sensitivity 86.9%.

Conclusions: SLN mapping in patients with gastric cancer is feasible and easy to perform. SLN mapping may mainly affect the extent of lymph node dissection, and to a lesser degree gastric resection. However, more data are needed.

Twenty years ago the Israeli Association of Allergy and Clinical Immunology was established, unifying these two fields into one speciality.

Objectives: To evaluate the extent and characteristics of CAM[1] use among cancer patients in northern Israel.

Methods: Telephone interviews were conducted with 2,176 newly registered cancer patients or their family members, at least 1 year following referral.

Results: The rates of CAM use varied significantly according to demographic characteristics and chemotherapy treatment, from 3% in the basically educated elderly group up to 69% of educated Israeli-born Jews younger than 70 years receiving chemotherapy. The overall rate of CAM use was 17%. The most influential factors determining CAM use were academic or high school education, chemotherapy treatment, Israel as country of birth, and age 41–50 years. All patients used CAM in addition to conventional therapies. Less than half of them reported it to their physicians. The most frequently used treatments were various chemical, biological, botanic and homeopathy remedies. Friends and relatives were the main recommenders of CAM. Most CAM users reported that they used CAM because they believed it “strengthens the immune system,” alleviates side effects of chemotherapy, improves quality of life and helps to overcome pain and stress, and 62% of them reported subjective beneficial effects.

Conclusions: A predicting module of CAM user patients was built, which may help physicians initiate conversations with their patients on CAM use. Expanding physicians' knowledge on CAM methods will encourage them to provide additional advice, promote the use of beneficial therapies, and inform patients about potentially harmful methods.

Melanoma is the leading cause of death from skin tumors worldwide, with an annual increase in incidence over the past decade. The molecular mechanisms involved in melanoma pathogenesis are beginning to be unraveled. While a family history of melanoma and exposure to ultraviolet irradiation have been known for years as risk factors in melanoma development, the precise genes involved in inherited predisposition were defined only in the past decade. Germline mutations in two genes that play a pivotal role in controlling cell cycle and division – CDKN2A and cyclin-dependent kinase 4 (CDK4) – have been detected in autosomal, dominant, high penetrance familial melanoma cases. In addition to these two highly penetrant genes, germline mutations and polymorphisms in a few low penetrance genes have been reported in familial melanoma cases: melanocortin-1 receptor, epidermal growth factor, glutathione s-transferase M1, cytochrome p450 debrisoquine hydroxylase locus (CYP2D6) and vitamin D receptor.

Background: The appearance of pericarditis following insertion of a permanent pacemaker is not widely acknowledged in the literature.

Objectives: To describe our experience with pericarditis following 395 permanent pacemaker implantations over 2 years.

Methods: We retrospectively reviewed the medical records of 395 consecutive patients in whom new pacing systems or pacemaker leads had been implanted over a 2 year period. We searched the records for pericarditis that developed within 1 month after pacemaker implantation according to the ICD-9 code. The incidence, clinical picture, response to treatment and relationship to lead design and location were studied.

Results: Eight cases (2%) of pericarditis following implantation were detected. Clinical manifestations in all patients were similar to those of post-pericardiotomy syndrome and included chest pain (n=7), friction rub (n=1), fever (n=2), fatigue (n=2), pleural effusion (n=2), new atrial fibrillation (n=2), elevated erythrocyte sedimentation rate (n=4) and echcardiographic evidence of pericardial effusion (n=8). All affected patients had undergone active fixation (screw-in) lead implantation in the atrial position. The incidence of pericarditis with screw-in atrial leads was 3% compared to 0% in other cases (P < 0.05).

Conclusions: Pericarditis is not uncommon following pacemaker implantation with active fixation atrial leads. Special attention should be paid to identifying pericardial complications following pacemaker implantation, especially when anticoagulant therapy is resumed or initiated. The use of passive fixation leads is likely to reduce the incidence of pericarditis but this issue should be further investigated.

Background: Recent advances in immunosuppressive therapy have led to a substantial improvement in the outcome of kidney transplantation. Living unrelated donors may become a source of additional organs for patients on the kidney waiting list.

Objectives: To study the impact of combination of calcineurin inhibitors and mycophenolate-mofetile, together with steroids, on outcomes of living related and unrelated transplants. 

Methods: Between September 1997 and January 2000, 129 patients underwent living related (n=80) or unrelated (n=49) kidney transplant. The mean follow-up was 28.2 months. Immunosuppressive protocols consisted of MMF[1] with cyclosporine (41%) or tacrolimus (59%), plus steroids. Patient and graft survival data, rejection rate, and graft functional parameters were compared between the groups.

Results: LUD[2] recipients were older (47.8 vs. 33.6 years) with higher number of re-transplants (24.5% vs. 11.2% in LRD[3] recipients, P < 0.05). Human leukocyte antigen matching was higher in LRD recipients (P < 0.001). Acute rejection developed in 28.6% of LUD and 27.5% of LRD transplants (P = NS). Creatinine levels at 1, 2 and 3 years post-transplant were 1.6, 1.7 and 1.7 mg/dl for LRD patients and 1.5, 1.5 and 1.3 mg/dl for LUD recipients (P = NS). There was no difference in patient survival rates between the groups. One, 2 and 3 year graft survival rates were similar in LRD (91.3%, 90% and 87.5%) and LUD (89.8%, 87.8% and 87.8%) recipients.

Conclusions: Despite HLA[4] disparity, rejection and survival rates of living unrelated transplants under current immunosuppressive protocols are comparable to those of living related transplants.

Background: Seroepidemeliogic surveys have provided valuable information on the prevalence and incidence of herpes simplex virus-2 infection in general and in selected populations.

Objective: To review the reliability of traditional diagnostic approaches in herpes simplex virus-2 infection.

Methods: In this cross-sectional study, 472 patients attending a clinic for sexually transmitted disease in 1998-1999 were evaluated for HSV-2 infection through collection of epidemiologic and clinical data.

HSV-2 infection was confirmed by the presence of specific Viral glycoprotein, gG-2, antibody in sera.

Results: The seroprevalence of HSV-2 among clinic attendees was 9.33%. Of these attendees only 22% presented with or reported a history of typical vesicular lesions in the genital area. Infection rate was  higher in patients with multiple sex partners (20.8% vs. 8.7%, P< ( 0.0023 in individuals aged 30 or older (12.6 vs. 6.4%, P = 0.03) and  in the Israeli Jewish population as compared to the Israeli Arab population (11.1% vs. 2.4%, P ~ 0.01). Females with multiple sex partners exhibited higher rates of infection than did their male counterparts (50 vs. 16.1%, P < 0.0275(.

Conclusion: The findings support the need for HSV-2 serologi  testing in patients presenting to STD clinics even when typical genital  lesions are not evident but where risk factors for HSV-2 infection are  identified.
 

Background: There are radiobiologic and technical advantages to the use of interstitial brachytherapy alone or as an adjunct to external beam radiotherapy in the postoperative treatment of soft tissue sarcomas.

Objectives: To review the experience of the Rambam Medical Center in implementing interstitial brachytherapy in the treatment of 32 patients with soft tissue sarcomas.

Methods: Thirty-two patients with variously located soft tissue sarcomas were managed with a combination of surgery and brachytherapy of the tumor bed, with or without EBRT[1]. In 27 of 32 patients, brachytherapy catheters were placed intraoperatively, while in 5 patients the implant was performed as a separate postoperative procedure. Twenty-seven patients received low dose-rate brachytherapy with iridium-192 seeds. Five patients received fractionated high dose-rate brachytherapy using the microSelectron machine.

Results: With a median follow-up of 36 months, the overall local control rate was 87.5%. Four of 32 patients (13%) failed locally at the implant site, and 6 (19%) developed lung metastasis. Two of the five patients with lung metastasis had a local recurrence as well. At the time of analysis, eight patients had died of sarcoma (disease-specific mortality rate was 25%), while three had died of intercurrent causes. The 5 year actuarial disease-free survival rate was 56%, and the 5 year actuarial overall survival was 70%. Five patients (16%) developed severe wound complications following surgery/brachytherapy, and six patients (19%) developed late local toxicity (fibrosis and telangiectasia).

Conclusions: Wide local excision followed by interstitial brachytherapy has resulted in an 87.5% local control rate with a 17% local complication rate.
