We report our preliminary experience of prenatal screening for Down's syndrome (DS) using nuchal translucency (NT) measurement combined with the serum biochemistry analysis of Free b-human chorionic gonadotropin (FbhCG) and pregnancy associated plasma protein A (PAPP-A) all measurement at 10-14 weeks of gestation.

Of the 358 parturient women which enrolled in the study, 9 cases were not included because of fetal anomalies or miscarriages. Thus the study group included 349 singleton pregnancies in which complete prenatal and infant follow-up was available.

Forty-four pregnant women were found to be screen positive (12.6%) and in 13 cases (27%) of them fetal chromosomal aneuploidies were diagnosed. Looking into the markers profile we found that the NT was a sensitive marker which was abnormally increased in all the fetal aneuploidies. Serum FbhCG was found to be a promising marker as well, being significantly elevated (2.26[0.86 multiple of the medians, MoM) in DS cases, and decreased (<0.5 MoM) in two cases of Edward's syndrome.

On the contrary, PAPP-A was found less sensitive, and its mean MoM values were not significantly different between DS versus euploid fetuses.

Our preliminary results support the promising success of DS screening using NT and FbhCG.

Inflammatory Bowel Disease and Osteoporosis: an Evidence-Based Connection

Eyal Meltzer, Eran Dolev,

Department of Internal Medicine E, Sourasky Medical Center and Sackler Faculty of Medicine, Tel-Aviv, Israel

Inflammatory bowel diseases (IBD) often have chronic or remittent course. Control of symptoms and disease activity often requires the administration of glucocorticoids.

Osteoporosis is a frequent finding in patients with IBD. The evidence-based connection between the two conditions relies on a relatively limited number of cross-sectional and longitudinal studies. The cause of this connection has not been defined completely. Probably, both the chronic inflammation and the steroid therapy contribute to the osteopenia, through an increase in bone resorption without a compensatory increase in bone formation. There is little data regarding the efficacy of therapeutic interventions for the prevention of osteoporosis in patients with IBD. Recently, guidelines for the evaluation and treatment of osteoporosis and IBD have been published. There is need for further research on the relation between these conditions and on the efficacy of current therapy for this unique population.

Department of Pediatrics, Bnei-Zion Medical Center, Faculty of Medicine, Technion, Haifa, Israel

Menetrier's disease in children is a rare disorder that is characterized by the presence of marked protein losing gastropathy associated with enlarged and thickened gastric folds. Abnormal regulation of gastric epithelial growth, probably triggered by an infectious agent, has been suggested as an etiology for this disorder. We describe a case of Menetrier's disease in a young child and review the current literature encompassing the different aspects of the disease.

Costs and Benefits of Laparoscopic Inguinal Hernia Repair- Is there an Economic Justification?

Background: With the recent accelerated development of laparoscopic surgery, it has been applied in all fields of surgery. The main issue today is not the technical ability of performing laparoscopic procedures but rather their justification while considering the disease and cost-benefit aspects.

Objectives: The present study surveys the experience accumulated in recent years concerning the economical aspects of laparoscopic inguinal hernia repair. Issues like length of the surgical procedure, cost, typical complications and recuperation time are being addressed.

Methods: We reviewed controlled clinical trials that compare laparoscopic and open repair of inguinal hernia. Trials that included at least 100 patients and were published in peer-reviewed journals since 1996 were included. Various operative techniques were compared using clinical and economical parameters.

Results: Most studies examined the issues from an institutional or health care system viewpoint and not from a comprehensive societal perspective. Therefore, indirect costs were seldom included. Operative times were longer and direct costs were significantly higher in the laparoscopic approach as compared to conventional open surgery. However, recovery time and return to work were found to occur earlier in patients who underwent laparoscopic surgery.

Conclusions: A shorter recovery time and shorter off-work period after laparoscopic hernia repair could compensate for the increased hospital expenditures. However, this contribution has not yet been completely established and needs further validation by supplementary studies. Other aspects that will have to be evaluated include quality of life and patient satisfaction.

The antiphospholipid syndrome (APS) is defined by the presence of antiphospholipid antibodies (aPLs) with venous or arterial thrombosis, recurrent pregnancy loss or thrombocytopenia. The syndrome can be either primary or secondary to an underlying condition, most commonly systemic lupus erythematosus (SLE).

The purpose of the study was to review the manifestations of the APS in Israeli patients and to investigate the difference between patients with primary or secondary syndrome. Analysis of the correlation between the manifestations of the disease and the antibody titers [LA (lupus anticoagulant), IgG aCL (anticardiolipin), IgM aCL] was also performed.

In the study there were 90 patients with APS in the Sheba Medical Center. The clinical findings for all patients were recorded according to established protocol.

Results: Arterial thrombotic events were present in 51.1% of the patients; cereberal ischemic attacks were the most frequent arterial events. Venous thrombotic events were present in 45.6% patients; deep venous thrombosis was the most frequent venous event. Obstetric complications were found in 37.3% of patients; the most frequent complication was abortions. The clinical findings of patients with primary or secondary syndrome were similar. Patients with APS associated with lupus had a high prevalence of hemolytic anemia (28.6% v 3.3%; P=0.001), and ANA (antinuclear antibody) (75% v 12.9%; P=0.0001). There was no correlation between the antibody titers (LA, IgG aCL, IgM aCL) and clinical manifestations. The patients received anticoagulant treatment and antiaggregant drugs to prevent recurrence of symptoms. Clinical manifestations in Israeli patients did not differ from those in non-Israeli patients.

Conclusions: Venous or arterial thrombosis and obstetric complications are the most frequent clinical findings in APS. There was no different in clinical manifestations between primary and secondary syndrome. The findings of autoimmune hemolytic anemia and ANA were more frequent in patients with secondary APS. There was no correlation between antiphospholipid antibody titers and manifestations of disease. Overall, the patients require therapy with anticoagulant treatment and antiaggregant drugs. The clinical manifestations were similar in Israeli and non-Israeli patients.

The aim of this article is to describe a community-based multi-modality intensive treatment program, which demonstrates a significant reduction in symptoms of eating disorders while providing an opportunity to deal with the functional and social skills. Treatment is delivered through a multidisciplinary team. The uniqueness of the team is in the inclusion of clinical mentors. These are social workers, art therapists and graduate level psychology students who are trained to connect with clients in an informal, intensive manner (10-40 hours a week). The mentors focus on legitimizing healthy attitudes to food, eating and life, while highlighting the pain and loss associated with the disorder. The mentors serve as meal companion and calming figure, representing the healthy self-caring voice. The relationship established during the many hours spent together becomes a powerful experience, completely different from the isolation of the disorder. The treatment intervenes in most areas of life, focusing on an active search for possibilities, in contrast to the emptiness associated with the disorder.

This article presents the results and principles of a 2.5-year practice. Seventeen patients, ill for 6 years and more, completed this program more than a year ago. An assessment of their BMI and their general outcome using Eckert scales was performed. One year after completing the program, 76% of the patients were defined as recovered and 12% were almost recovered with only a few remaining symptoms. All of these patients function satisfactorily in the community, both in social and occupational aspects. Six percent were partially recovered and 6% suffered from regression during the first year of follow-up.

This treatment provides the intensity required in hospitalizations, while enabling patients to stay in the community and maintain those activities that survive the disorder. This program has proven to work well with chronic patients. Further data, not analyzed as yet, also indicates the efficacy of this treatment in acute cases.

The treatment of traumatic false aneurysm of the thoracic aorta by endovascular stent graft may have advantages over conventional surgery. This is a case study of two women suffering from false aneurysm of the thoracic aorta caused in one by a knife injury and in the other by a car accident. After the patients became hemodynamically stable, a commercially available endothelial stent graft (Talent, Gor) was deployed. Recovery was rapid in the first patient. The second patient required emergency laparotomy for venous bleeding one day after stent placement; she died two weeks later, mainly from organ failure.

Conclusions: Endovascular techniques can be used in selected cases to treat thoracic false aneurysms thereby avoiding the complexity and morbidity of conventional surgery.

Non-steroidal anti-inflammatory drugs (NSAID) are potent analgesic agents. They are indicated for rheumatoid arthritis, osteoarthritis, severe acute and prolonged chronic pain. A wide range of analgesic agents are available. The objective of this study was to assess the patient's knowledge of his illness, his knowledge familiarity with NSAID medications and their side effects and thereupon, to evaluate the awareness, utilization, satisfaction and expectations associated with current available treatment.

During the year 2000, a randomized telephone screening questionnaire, was completed over a 2 month period for a sample group of the general Israeli population over 50 years of age.

Of the 3179 persons contacted, 2028 responded and 292 persons were treated with NSAIDs and further investigated. Fifty percent suffered from chronic musculoskeletal pain, 22% had osteoarthritis, 10% had rheumatoid arthritis, and 18% had undefined chronic pain. The average age of the respondent was 65 years old. The average duration of treatment was 11 years. The most common drugs used by the 292 respondents that were taking NSAIDs were diclofenac (Voltaren) - 51% and naproxen (Naxyn) - 21%. Only 4% were treated with COX-2 specific inhibitors. Twenty percent of the respondents utilized more than one NSAID simultaneously. Forty seven percent of the patients had peptic ulcer disease but only 39% of them were simultaneously treated with an NSAID and a gastroprotective agent. Sixty eight percent of patients expected amelioration of symptoms while taking NSAIDs. Seventy seven percent of respondents were dissatisfied with treatment. The patients expressed that they did not have a reliable easily accessible source of information on their disorder or on available treatment options.

Many respondents were not aware of their medical diagnosis. In general, patients were not aware of all the available NSAIDs or the side effects of gastrointestinal complications. Enhancement of information available to the patient is warranted to improve the provision of efficient therapy, reduce side effects and increase patient satisfaction from therapy.

We report a case of a 22 year old man with a history of bronchial asthma, suffering from diarrhea, eosinophilic ascites and prominent blood and bone marrow eosinophilia. The patient responded to corticosteroid treatment.

Later, hydroxyurea was added to this treatment because of recurrence of eosinophilia, ascites and hepatosplenomegaly.

Eosinophilic ascites is rarely the outstanding symptom of the hypereosinophilic syndrome.

Following the exclusion of other reasons for eosinophilia, concomitant unexplained hepatosplenomegaly suggested the diagnosis of a hyperereosinophilic syndrome.

Introduction: Sentinel lymph node biopsy (SLNB) has been recently proven to be an accurate staging method for breast cancer, replacing axillary lymph node dissection (ALND) in selected cases. We present our initial experience and the process of introduction and implementation of SLNB in a University Hospital setting.

Material and methods: 46 SLNB were performed in 42 consecutive female patients with invasive breast cancer. Treatment included 0.4mCi-2mCi of Tc-99m rhenium colloid injected either 2 hours before surgery (0.4 mCi) or the night before surgery (2 mCi). Four milliliters of Patent Blue V were injected peritumoral 10 minutes prior to skin incision in all patients. Following SLNB all women underwent subsequent ALND. Sentinel nodes were processed both with multiple (10-15) H&E sections and immunohistochemistry with cytokeratin antibodies stain.

Results: Blue dye, isotope or the combination of both identified 43/46 (93%) of the sentinel lymph nodes. ALND was performed only unilaterally in 4 patients with bilateral breast cancer bringing the total evaluable SLNB to 39. In the 39 patients in whom the sentinel node was successfully identified and underwent ALND, the SLNB was true positive (TP) in 17/39 (44%) true negative (TN) in 20/39 (51%) and false negative in 2/39 [(5%), both T2 lesions] with overall accuracy of 95%. In the last 10 cases all sentinel nodes were successfully identified with 70% TP and 30% TN.

Conclusions: Experience with at least 30-40 consecutive cases for safe implementation of SLNB in clinical practice. Specific training and dedication is required for the entire team involved, including surgeons, nuclear medicine physicians and technicians and pathologists.

Introduction: Surgery is the treatment of choice in most early stages of cervical cancer and advanced stages of ovarian cancer. Failing to preoperatively diagnose para-aortic and parametrial metastases in cervical cancer or a non-resectable, ovarian cancer, may results in a superfluous laparotomy.

Aim: To evaluate the advantage of using laparoscopy in cervical and ovarian cancer.

Patients and Methods: Study population includes patients with ovarian or cervical cancer referred between 1997-1999. A CT scan and a trans-vaginal sonography were used to detect involvement of pelvic and para-aortic lymph nodes, parametrium and other metastases. In patients with cervical cancer, para-aortic lymph node dissection was laparoscopically performed. When para-aortic nodes were negative and parametrium was clear, radical hysterectomy and pelvic lymph nodes dissection was conducted through laparotomy. When para-aortic lymph nodes or parametrium were positive, patients were referred for radiation therapy. In ovarian cancer patients, the upper abdomen and the pelvis were examined laparoscopically to evaluate the possibility of optimal debulking surgery. Staging was done for patients who were not candidates for optimal debulking surgery and second debulking surgery was considered.

Results: Nine patients with stage lb-lla cervical cancer were included. Preoperatively, 2 of them were suspected for lymph node involvement. Following laparoscopy one was confirmed to have para-aortic lymph node involvement and the other did not. In the remaining 8 patients, one was found to have parametrial involvement and laparotomy was avoided, while the rest were treated surgically.

Eighteen ovarian cancer patients were included in this study. Laparoscopy revealed an extensive disease in 7 patients and therefore staging laparoscopy was completed. In the remaining 11 patients, laparotomy was performed, operable disease was found and complete debulking surgery was conducted. In only one patient of the 11 complete debulking surgeries was not possible.

Conclusions: In accordance with the experience and skills of the surgical team, we propose utilizing laparoscopy in cases where laparotomy may be avoided.
