Background: Non-operative management following abdominal stab wounds is possible in selected patients who are both hemodynamically stable and do not have signs of peritonitis. However, the rate of failure of non-operative management is higher in Israel than in western countries.

Objectives: To assess the patterns of injury following abdominal stabbing.

Methods: Data from the Israeli Trauma Registry were used to identify all patients with abdominal stab injury admitted to eight different trauma centers between 1997 and 2004.

Results: The number of patients admitted per year more than doubled between 1997 and 2004, from 257 to 599. The percentage of patients with severe injury (Index Severity Score ≥ 16) increased from 9.4% to 19.0%. The incidence of multiple stab injuries almost doubled, from 37% to 62%.

Conclusions: Review of the data in the Israeli Trauma Registry indicates an increase in both absolute rate and relative incidence of serious stab injuries. This indicates that patterns of injury following stab wounds are not necessarily similar, not even within the same geographical area over time.
 

Background: Patients with end-stage renal disease are at high risk of mycobacterial infection.

Objectives: To analyze the difficulties in reaching an accurate diagnosis of tuberculosis in dialysis patients.

Methods: We conducted a retrospective follow-up of patients who attended our peritoneal and hemodialysis units during the 10 year period 1995–2005.

Results: Our dialysis unit diagnosed 10 cases of tuberculosis caused by Mycobacterium tuberculosis and 9 cases of Mycobacterium other than tuberculosis. In the former group, five patients had mycobacterium in the sputum, which was diagnosed by intraabdominal mass biopsy in one, culture of the gastric juices in one, and pleural fluid culture or pleural biopsy in three. One of these patients was suffering from pleural TB[1] as well as Potts disease. Of the patients with Mycobacterium other than tuberculosis, five were diagnosed by sputum cultures, three by urine cultures and one in peritoneal fluid. Differences in treatment and outcome were also reviewed.

Conclusions: The diagnosis of TB in dialysis patients should be approached with a high index of suspicion. It is clear that extensive diagnostic procedures are required to ensure an accurate diagnosis of the disease. Tuberculosis incurs a significant added burden due to the need for isolation of infected patients within the dialysis unit. Treatment of patients with Mycobacterium other than tuberculosis should be addressed individually.

Background: Femoral artery vascular complications are the most common adverse events following cardiac catheterization. Smaller diameter introducer sheaths and catheters are likely to lower the puncture site complication rate but may hinder visualization.

Objectives: To evaluate the safety and angiographic quality of 4 French catheters.

Methods: The study was designed to simulate real-life operator-based experience. Diagnostic angiography was performed with either 4F or 6F diagnostic catheters; the size of the catheter used in each patient was predetermined by the day of the month. Patients undergoing 4F and 6F diagnostic angiography were ambulated after 4 and 6 hours, respectively. The following technical parameters were recorded by the operator: ease of introducer sheath insertion, ease of coronary intubation, ease of injection, coronary opacification, collateral flow demonstration, and overall assessment. Adverse events were recorded in all patients and included minor bleeding, major bleeding (necessitating blood transfusion), minor hematoma, major hematoma, pseudo-aneurysm formation and arteriovenous fistula.

Results: The study group included 177 patients, of whom 91 were in the 4F arm and 86 in the 6F arm. Demographic and procedural data were similar in both groups. Seventy-seven percent of 6F and 50% of 4F procedures were evaluated as excellent (P < 0.05). This difference was attributed to easier intubation of the coronary ostium and contrast material injection, increased opacification of the coronary arteries, and demonstration of collateral flow with 6F catheters. Complications occurred in 22% of patients treated with 6F catheters and 10% of those treated with 4F catheters (P = 0.11). Of the 50 patients who switched from 4F to 6F 12% had complications. In patients undergoing diagnostic angiography, the complication rate was 10% vs. 27% (most of them minor) in the 4F and 6F groups, respectively (P < 0.05).
Conclusions: Patients catheterized with 4F have fewer complications compared with 6F diagnostic catheters even when ambulated earlier. Although 4F had a reduced quality compared to 6F angiographies, they were evaluated as satisfactory or excellent in quality 85% of the time. 4F catheters have a potential for reduced hospitalization stay and are a good option for primary catheterization in patients not anticipated to undergo coronary intervention

The human papillomavirus family of viruses causes a variety of benign, premalignant and malignant lesions in men and women. All cervical cancers are caused by HPV[1]. It is the leading cause of death from cancer in women in developing countries; every year some 493,000 women develop cervical cancer and 230,000 women die every year of this disease. The vaccine against HPV includes virus-like particles, composed of the major viral capsid protein of HPV without the carcinogenic genetic core. Large-scale studies have shown that the vaccine is tolerated well, leads to high antibody levels in both men and women, and prevents chronic HPV infection and its associated diseases. To achieve effective coverage the vaccine should be given prior to sexual debut. Introduction of the vaccine into specific countries, particularly Israel, should take into account the local incidence of cervical cancer as well as the increasing incidence of precancerous cervical lesions and genital warts, which reduce quality of life and are associated with considerable costs.

This paper does not attempt to deal with the legitimate ethical or moral debate on abortion. Utilizing abortion as a subject I will show how science and medicine in general, and abortion in particular, were used as weapons of mass destruction by Nazi physicians in their zeal to comply with the political climate of the time. Nazi policy on abortion and childbirth was just one of the methods devised and designed to ensure the extermination of those whom the Nazis deemed had "lives not worth living." Physicians implemented these policies, not with the fate of their patients in mind, but rather in the name of the "state." When discussing pregnancy, abortion and childbirth during the Holocaust it is imperative to include an essay of how these issues affected the Jewish prisoner doctors in the ghettos and camps. Nazi policy dictated their actions too. From an extensive search of their testimonies, I conclude that for these doctors ethical discourse comprised a fundamental component of their functioning. I do not propose to judge them in any way and one should not, in my opinion, argue whether their behavior was or was not morally acceptable under such duress; nevertheless, unlike their Nazi counterparts, a key theme in their testimonies was to "keep their medical values."

Background: Decreased lacrimal gland output may cause dry eye syndrome. Using a rat model, we examined the feasibility of transplanting lacrimal gland cells from newborns.

Objectives: To restore lacrimal gland function in eyes with compromised tear production.

Methods: A model of dry eye in adult rats was developed by unilateral surgical removal of the main lacrimal gland. Tear secretion in both eyes was then assessed by masked Schirmer's test. Lacrimal gland tissue from newborn rats was transplanted into the fibrous connective tissue in which the lacrimal gland had been embedded. Masked Schirmer's test was repeated 4, 8 and 12 weeks after transplantation.

Results: Schirmer's test performed in 13 rats 10 days after unilateral lacrimal gland excision revealed significantly less wetting on the side with excised gland compared with the normal side (P < 0.003). The lack of secreting cells on the operated side was verified histologically. The reduction in tear secretion on the operated side remained significant for 8 weeks on average. In the six rats with transplanted lacrimal gland tissue however, there were no differences in tear reduction between the two eyes at 4, 8 or 12 weeks after the operation (P = 0.81, 0.56 and 0.8, respectively).

Conclusions: Transplantation of lacrimal gland tissue from newborn rats effectively restored eye wetting in this new model. Further research is needed to evaluate this new approach for treating lacrimal gland dysfunction. Using this model might also facilitate evaluation of potential clinical treatments for dry eyes.
 

Objective: To report our experience with terlipressin treatment for facilitation of transport to distant facilities for diagnostic or therapeutic procedures in septic patients treated with norepinephrine.

Methods:  We conducted a retrospective analysis of the records of our ICU[1], identifying the patients with septic shock who required norepinephrine for hemodynamic support.

Results: Terlipressin was given to 30 septic shock patients (15 females and 15 males) who were on high dose norepinephrine (10 μg/min or more) in order to facilitate their transport outside the ICU. The dose of terlipressin ranged from 1 to 4 mg, with a mean of 2.13 ± 0.68 mg. The dose of norepinephrine needed to maintain systolic blood pressure above 100 mmHg decreased following terlipressin administration, from 21.9 ± 10.4 μg/min (range 5–52 μg/min) to 1.0 ± 1.95 (range 0–10) (P < 0.001). No patients required norepinephrine dose adjustment during transport. No serious complications or overshoot in blood pressure values were observed following terlipressin administration. Acrocyanosis occurred only in eight patients receiving more than 1 mg of the drug. The overall mortality rate was 50%.

Conclusions: Our data suggest that terlipressin is effective in septic shock. Because it is long-acting and necessitates less titration it might be indicated for patient transportation.

Contamination of food with streptococci could present with unusual outbreaks that may be difficult to recognize in the early stages. This is demonstrated in a large food-borne outbreak of streptococcal pharyngitis that occurred in 2003 in a factory in Israel. The outbreak was reported to the public health services on July 2 and an epidemiologic investigation was initiated. Cases and controls were interviewed and throat swabs taken. An estimated 212 cases occurred within the first 4 days, the peak occurring on the second day. There was a wave of secondary cases during an additional 11 days. The early signs were of a respiratory illness including sore throat, weakness and fever, with high absenteeism rates suggesting a respiratory illness. As part of a case-control study, cases and controls were interviewed and throat swabs taken. Illness was significantly associated with consumption of egg-mayonnaise salad (odds ratio 4.2, 95% confidence interval 1.4–12.6), suggesting an incubation period of 12–96 hours. The initial respiratory signs of food-borne streptococcal pharyngitis outbreaks could delay the identification of the vehicle of transmission. This could be particularly problematic in the event of deliberate contamination.
