The care of the trauma victim can be divided into five to six phases, none of which can be bypassed.

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

The first Trauma Unit in Israel was founded at the Hadassah (Ein Kerem) Medical Center in 1992 - the result of increased awareness to the new concept of optimal care for the injured patient.

Intravascular lymphoma is a rare sub-type of extranodal diffuse large B cell lymphoma characterized by the presence of lymphoma cells only in the lumina of small vessels, particulary capillaries

Dirofilariasis is a parasitic disease of domestic and wild animals that occasionally appears in humans.

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

Background: Ischemic mitral regurgitation is associated with reduced survival after coronary artery bypass surgery.

Objectives: To compare long-term survival among patients undergoing coronary surgery for reduced left ventricular function and severe ischemic MR[1] in whom the valve was either repaired, replaced, or no intervention was performed.

Methods: Eighty patients with severe left ventricular dysfunction and severe MR underwent coronary bypass surgery. The mean age of the patients was 65 years (range 42–82), and 63 (79%) were male. Sixty-three (79%) were in preoperative NYHA functional class III-IV (mean NYHA 3.3), and 26 (32%) were operated on an urgent/emergent basis. Coronary artery bypass surgery was performed in all patients. The mitral valve was repaired in 38 and replaced in 14, and in 28 there was no intervention. The clinical profile was similar in the three groups, although patients undergoing repair were slightly younger.

Results: Operative mortality was 15% (8%, 14%, and 25% for the repair, replacement and no intervention respectively; not significant). Long-term follow up was 100% complete, for a mean of 38 months (range 2–92). Twenty-nine patients (57%) were in NYHA I-II (mean NYHA 2.3). Among the surgery survivors, late survival was improved in the repair group compared to the other groups (P < 0.05). Predictors for late mortality were non-repair of the mitral valve, residual MR, and stroke (P = 0.005).

Conclusions: Patients with severe ischemic cardiomyopathy and severe MR undergoing coronary bypass surgery should have a mitral procedure at the time of surgery. Mitral valve repair offers a survival advantage as compared to replacement or no intervention on the valve. Patients with residual MR had the worst results.

Background: The 5 year survival rate in patients with advanced epithelial ovarian cancer is 25–40% and treatment is mainly palliative once the disease recurs.

Objectives: To determine the time to progression, overall survival and toxicity of 1 year maintenance treatment with carboplatin in women with advanced EOC[1] after achieving complete remission with platinum‑based combination chemotherapy.

Methods: Twenty-two women with epithelial ovarian cancer stage III-IV previously treated with platinum‑based combinations who had achieved complete remission evidenced by symptoms, pelvic examination, computerized tomography and serum CA-125, were assigned to the study protocol consisting of: carboplatin of AUC=6, three cycles every 2 months, followed by two cycles once every 3 months for a total of five courses over 1 year.

Results: Median follow‑up in the 22 patients was 83 months (range 18–133 months), median disease‑free survival was 36 months (range 2.5–126.4, 95% confidence interval 16.39–56.34). The 5 year survival was 59.7% with a mean overall survival of 83 months (range 18–133, 95% CI[2] 39.11-127.29). Eleven patients have relapsed and died, 11 are alive, 6 are still in complete remission, and 5 are alive with recurrent disease. Grade III-IV toxicity was shown in some of the patients, anemia in 9%, thrombocytopenia in 9%, fatigue in 4.5%, and hypersensitivity in 4.5%.

Conclusions: A 1 year extension of treatment with a single‑agent carboplatin, administered to women with advanced EOC who had achieved complete recovery on platinum‑based chemotherapy as their first‑line therapy, has an acceptable toxicity. The disease-free survival and overall survival values noted in this study are encouraging and warrant further investigation.

Background: The prevalence of morbid obesity is increasing rapidly. Weight reduction is very difficult using diet restriction and physical activity alone. Sibutramine has been shown to be effective and safe as an adjuvant therapy to diet restrictions.

Objectives: To describe our experience using sibutramine in weight reduction treatment of adolescents suffering from morbid obesity.

Methods: The study group comprised 20 young persons (13 females, mean age 15 years 4 months, range 13–18 years) with morbid obesity (body mass index over the 95th percentile for age and/or ≥ 30 kg/m²) were treated with sibutramine 10 mg once a day for 1 year.

Results: Mean BMI[1] was 40 ± 5.6 kg/m² (range 30.1–49.5 kg/m²) at the beginning of treatment. Most patients showed an early weight reduction to mean BMI 39.3 ± 4.9 and 35.9 ± 5.7 at 3 and 6 months respectively, but stopped losing weight over the next 6 months. During the follow-up period 17 patients discontinued the treatment. The main reason for dropout was the slow rate of weight reduction after 6 months. Patients suffering from concomitant disorders (severe asthma, hypertension, sleep obstructive apnea) showed improvement after weight reduction. Adverse reactions from the treatment were transient, mild and well tolerated.

Conclusions: Sibutramine may help in achieving weight reduction for a short period and in improving concomitant health problems, however its long-term effect is limited.

Background: Advanced glycation end products, formed by the non-enzymatic glycation of proteins with reducing sugars, are thought to play a pathogenetic role in the vascular complications of diabetes, uremia and atherosclerosis. β2-microglobulin is a major constituent of amyloid fibrils in dialysis-related amyloidosis. AGE[1]-modified β2m[2] has been found in amyloid deposits of long-term hemodialysis patients. AGE-modified β2m has also been shown to enhance chemotaxis and increase tumor necrosis factor-alpha and interleukin-1 beta secretion by circulating and tissue monocytes/macrophages.

Objectives: To investigate the effect of AGE-modified β2m and AGE-human serum albumin on TNF-α[3] and IL-1β[4] secretion by human peritoneal macrophages derived from patients on continuous ambulatory peritoneal dialysis.

Methods: Human PMØ[5] were isolated from peritoneal dialysis effluent of stable CAPD[6] patients and were incubated for 24 hours with AGE-modified β2m, β2m, AGE-HSA[7], HSA or lipopolysaccharide. TNF-α or IL-1β secretion was measured by enzyme-linked immunosorbent assay in cell-free culture supernatants.

Results: Both AGE-modified β2m and AGE-HSA significantly increased TNF-α and IL-1β secretion by human PMØ in a dose-dependent manner (50–200 μg/ml). In contrast, β2m or HSA had no such stimulatory effect on TNF-α secretion but had a small significant increase in IL-1β secretion.

Conclusions: AGE-modified β2m promotes in vitro TNF-α and IL-1β secretion by human PMØ of CAPD patients. Activation of these macrophages by AGE-modified β2m may be a contributory factor to the morphologic changes and altered permeability of the peritoneal membrane in long-term CAPD. 

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.

"Surviving severe injury depends very heavily upon the time it takes to receive trauma services. The risk of death increases three fold after one hour without the uniqe surgical care of a trauma center. This is often referred to as the 'golden hour'..."
