Autoinflammatory (AIF) and autoimmune (AIM) diseases are chronic immune disorders characterized by dysregulation of the immune system. Most AIF diseases are monogenic diseases which lead to hyperactivation of the inflammasome and release of pro-inflammatory cytokines, such as interleukin-1 (IL-1) and IL-18, resulting in tissue inflammation. Besides, the main feature of autoimmune diseases is the loss of tolerance of the adaptive immune cells against self antigens. Most AIF diseases are polygenic and numerous immune pathogens are involved in organ damage. The involvement of some AIF-associated mechanisms in AIM diseases, i.e., the activation of the inflammasome and the role of IL-1, was recently recognized. Moreover, some single nucleotide polymorphisms of the inflammasome genes have been proven to be involved in the development of AIF-related inflammatory features in autoimmune patients. These observations raise the possibility of using some anti-inflammatory drugs, like IL-1 antagonists, in autoimmune diseases with autoinflammatory features.

Background: Removal of retained placental tissue postpartum and retained products of conception (RPOC) abortion is done by uterine curettage or hysteroscopy. Trauma to the endometrium from surgical procedures, primarily curettage, can cause intrauterine adhesions (Asherman's syndrome) and subsequent infertility. The incidence of malpractice claims relating to intrauterine adhesions is rising, justifying reevaluation of the optimal way of handling these complications. 

Objectives: To review malpractice claims regarding intrauterine adhesions, and to explore the clinical approach that might reduce those claims or improve their medical and legal outcomes.

Methods: We examined 42 Asherman's syndrome claims handled by MCI, the largest professional liability insurer in Israel. The clinical chart of each case was reviewed and analyzed by the event preceding the adhesion formations, timing and mode of diagnosis, and outcome. We also assessed whether the adverse outcome was caused by substandard care and it it could have been avoided by different clinical practice. The legal outcome was also evaluated.

Results: Forty-seven percent of the cases occurred following vaginal delivery, 19% followed cesarean section, 28% were RPOC following a first-trimester pregnancy termination, and 2% followed a second-trimester pregnancy termination.

Conclusions: It is apparent that due to a lack of an accepted management protocol for cases of RPOC, it is difficult to legally defend those cases when the complication of Asherman syndrome develops.

Background: Appendectomies are the most common operations performed on an emergency basis. The accepted rate of "white" appendectomies is around 20%. In recent years, computed tomography (CT) scanning has been recognized as a valuable tool with high sensitivity and specificity in the diagnosis of acute appendicitis. The use of CT scans in the management of patients with suspected acute appendicitis is increasing worldwide.

Objectives: To assess whether introducing more liberal use of CT in the management of patients presenting to the emergency room with right lower quadrant pain or suspected acute appendicitis would reduce the rate of “white” appendectomies.

Methods: We conducted a retrospective study of the pathology reports and CT scans of all patients who underwent appendectomy during a 3 year period. We examined the correlation between the rate of CT scans performed and the rate of "white" appendectomies.

Results: Overall, we performed 797 appendectomies during the study period. In 2004, we performed 272 appendectomies and CT in 34 patients (12.5%). In 2005, we performed 275 appendectomies and CT in 83 patients (30.2%). In 2006, we performed 250 appendectomies and CT in 88 patients (35.2%). The percentage of "white" appendectomies decreased from 29% in 2004 to 21.1% in 2005 and to 18.8% in 2006.

Conclusions: It appears that a more selective use of CT scans in the management of suspected appendicitis could reduce the rate of "white" appendectomies.

Background: The "see and treat" approach, proceeding without a biopsy directly to uterine cervix conization in women diagnosed with high grade squamous intraepithelial lesion (HGSIL) on Pap smear, shortens the treatment duration, lessens patient anxiety, and reduces health care costs.

Objectives: To evaluate the level of diagnostic accuracy and the over-treatment rate in the "see and treat" versus conventional management of women diagnosed with HGSIL.

Methods: We retrospectively reviewed all women with HGSIL who had undergone the "see and treat" approach during 2001–2011 at Soroka University Medical Center. Similar cohorts, who were managed conventionally with a cervical biopsy prior to the conization, served as a comparison group.

Results: The study population consisted of 403 women: 72 (18%) had undergone the "see and treat" approach and 331 (82%) conventional management. The false positive rate was 11% for the "see and treat" group, compared to 6% for the conventional management group (P = 0.162). Similarly, no statistically significant difference was observed when comparing the positive predictive value (PPV) of high grade dysplasia diagnosed on Pap smear (PPV 88.9%) versus cervical biopsy (PPV 93.8%) (P = 0.204). Moreover, both the false positive rate and PPV remained similar in subgroups of patients, according to age, menopausal status, number of births, and colposcopy findings.

Conclusions: The accuracy level of HGSIL diagnosis on Pap smear is similar to that of high grade dysplasia on a cervical biopsy. We therefore recommend referring patients with HGSIL directly to conization. Skipping the biopsy step was not associated with significant over-treatment or other adverse effects.

Background: A 75 year old patient presenting with mucocutaneous bleeding was diagnosed with acquired thrombastheniaThe diagnosis was based on lack of platelet aggregation with adenosine diphosphate (ADP), arachidonic acid and collagen, and normal aggregation induced by ristocetin.

Objective: To study the mechanism of platelet function inhibition in a patient with acquired thrombasthenia.

Methods: Aggregation assays of platelets from the patient and healthy controls were performed. In addition, anti-glycoprotein (GP) IIbIIIa antibodies binding to normal platelets in the presence or absence of the patient’s serum was studied by flow cytometry.

Results: Aggregation of normal platelets in the presence of patient's plasma was inhibited four- and 2.5-fold in the presence of ADP and arachidonic acid respectively, while collagen-induced aggregation was completely abolished. Ristocetin-induced aggregation was normal. The patient's serum inhibited binding of commercial anti-glycoprotein IIbIIIa antibodies to normal platelets twofold by flow cytometry. Treatment with anti-CD20 monoclonal antibody (rituximab) normalized the patient's platelet aggregation.

Conclusions: These results suggest that the patient developed inhibitory anti-GPIIbIIIa autoantibodies that caused acquired thrombasthenia.

All victims of violence encountered in our emergency rooms and clinics need to be recognized and documented as such. Although there has been progress in the implementation of rules concerning (domestic) violence against women, children and the elderly, the management of cases where patients have been subjected to violence while under the custody of legal enforcement agencies, or patients who have been victims of torture, is still not sufficiently standardized. We describe the Istanbul Protocol of the United Nations, an excellent tool that can help physicians and health professionals recognize and treat cases of torture or institutional violence.

Erythema nodosum and pyoderma gangrenosum are common skin manifestations in inflammatory bowel diseases. Curiously, these two cutaneous features have seldom been reported to occur simultaneously.  We present three patients affected with inflammatory bowel disease, with concomitant erythema nodosum and pyoderma gangrenosum.

 Background: Physicians are often insufficiently trained in bedside teaching and mentoring skills. Objectives: To develop, implement and assess a simulation-based training program designed to improve clinical teaching among physicians.

Methods: We developed a one-day tutor training program based on six simulated scenarios with video-based debriefing. The program's efficacy was assessed using questionnaires completed by the participating physicians and their students. Main outcome measures were self-perceived teaching skills at baseline, after participation in the program, and following completion of the tutor role. Secondary outcome measures were the students' perceptions regarding their tutor skills.

Results: Thirty-two physicians (mean age 35.5, 56% females) participated in the program. Self-assessment questionnaires indicated statistically significant improvement following the program in 13 of 20 measures of teaching skills. Additional improvement was observed upon completion of the tutor role, leading to significant improvement in 19 of the 20 measures. Questionnaires completed by their students indicated higher scores in all parameters as compared to a matched control group of tutors who did not participate in the program, though not statistically significant. Most participants stated that the program enhanced their teaching skills (88%), they implement program-acquired skills when teaching students (79%), and they would recommend it to their peers (100%). Satisfaction was similar among participants with and without previous teaching experience.

Conclusions: A novel one-day simulation-based tutor training program was developed and implemented with encouraging results regarding its potential to improve clinical teaching and mentoring skills.

Background: Homozygous carriers of factor V Leiden (FVL) have an up to 80-fold increased risk of venous thrombosis, but the risk of obstetric complications in FVL homozygosity is unclear.

Objectives:
To compare obstetric and thromboembolic complications among factor V Leiden (FVL) homozygous and heterozygous carriers treated with prophylactic dose anticoagulation during pregnancy.

Methods:
In this retrospective case-control study we performed a chart review for the years 2004–2010 of homozygous and heterozygous FVL carriers who were treated with low molecular weight heparin (LMWH) at a dose of 0.6 mg/kg/day during pregnancy. Adverse outcomes included thromboembolic and obstetric complications. A composite adverse obstetric outcome was defined as the presence of at least one of the following: late intrauterine fetal demise, severe intrauterine growth restriction (< 5th percentile), preeclampsia, placental abruption. Pregnancy outcomes of homozygous and heterozygous FVL carriers were compared.

Results:
We compared the pregnancies of 13 homozygous FVL women with those of 82 heterozygous FVL carriers. Thromboembolic events occurred only in heterozygous FVL controls. Gestational age and birth weight were similar. The composite adverse obstetric outcome rate was higher for homozygous compared with heterozygous FVL carriers (23.1% vs. 11%, respectively), although not statistically significant. A trend for prematurity among homozygous FVL patients was evident, with 2/13 women (15.3%) in the homozygous FVL group giving birth before 34 weeks gestation, compared with only 2/82 (2.3%) in the heterozygous group.

Conclusions:
Pregnancy outcome was similar for homozygous and heterozygous FVL carriers on LMWH thromboprophylaxis. The overall likelihood of thromboembolic complications was low. Thromboprophylaxis may decrease the risk for placental and thromboembolic complications in homozygous FVL patients to a similar level as in heterozygotes.

 Throughout history religious figures have been intimately involved in caring for the sick. Not only have they prayed for the welfare of the sick and arranged for their care but in many instances provided medical care as well. With the advent of scientific medicine, the responsibility for medical care was transferred to trained physicians. A new phenomenon has recently emerged in Israel that has threatened this ‘division of labor’ between physicians and rabbis, namely, the establishment of medical navigation organizations. Medical navigation can improve access to highly specialized care and help build trust between doctors and patients. However, this system is accompanied by numerous ethical and professional difficulties. For example, it is not clear how referrals are made and to what extent the system should be regulated. The phenomenon needs to be further studied to determine its prevalence in Israeli society as well as its impact on the practice of medicine from the perspective of both physicians and patients.
