Thrombosis is a common phenomenon in patients with malignancies. It is believed that thrombosis is multifactorial and that in addition to mechanisms directly associated with cancer and its treatment, it may also be related to the interaction between the immune system and clotting. The present work describes four cancer patients (three adults and one child) whose clinical course was characteristic of catastrophic antiphospholipid syndrome (CAPS) in intensive care units of the National Cancer Institute of Rio de Janeiro. The presence of findings similar to those in CAPS can be attributed to an unbalanced interaction between the immune system and coagulation.

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.

Giant cell arteritis (GCA) is considered to be a T cell-dependent disease. Autoantibodies have not consistently been found in GCA. The exception is antiphospholipid antibodies (APLA), which were found in 30–80% of GCA cases. Recently, efforts have been made to seek autoantibodies in GCA using newer methods of detection: serological identification of antigens by recombinant cDNA expression cloning, and a proteomic approach. In these studies, lamin C (a nuclear envelope antigen) was recognized by antibodies in 32% of GCA sera and none of the controls. Other autoantigenic proteins were also identified: lamin A, vinculin (a cytoskeleton antigen), and annexin 5 (an endothelial protein). In a recent study, 92% of 36 patients with GCA and/or polymyalgia rheumatica (PMR) had autoantibodies to a human ferritin peptide (the heavy chain N-terminal); 89% had antibodies to bacterial ferritin peptide of Staphylococcus epidermidis. The significance of these findings needs to be studied further. GCA may be a part of the newly described ASIA syndrome (autoimmune syndrome induced by adjuvants). A recent study from Italy reported 10 cases of GCA/PMR within 3 months of influenza vaccination. These comprised 50% of all cases of GCA/PMR diagnosed during the 6 year period of the study. Another 11 cases of GCA following influenza vaccinations were reported. GCA pathogenesis involves all branches of the immune system, including antigen-presenting cells, T cells and B cells, and autoantibody formation is not uncommon. GCA etiology remains unknown, but may be associated with exposure to bacterial or viral antigens.

Background: Cogan’s syndrome (CS) is a rare autoimmune vasculitis characterized by ocular inflammation and sensorineural hearing loss. CS is divided into a “typical” form with non-syphilitic interstitial keratitis and audiovestibular symptoms, and an “atypical” form with ocular involvement affecting structures other than the cornea. Anti-Hsp70 antibodies were found at variable levels in patients presenting with various forms of autoimmune sensorineural hearing loss (ASNHL).

Objectives: To assess the correlation between anti-Hsp70 antibodies and specific ASNHL subgroups.

Methods: We divided 112 subjects into four groups: 14 subjects with typical CS, 24 with atypical CS, 55 with ASNHL, and 19 control subjects (healthy subjects and patients with systemic autoimmune diseases but no sensorineural hearing or audiovestibular alterations). Patients were tested for serological autoimmunity markers including anti-Hsp70.

Results: Positivity of the anti-Hsp70 antibody test was highest in the typical CS group (92.9%) and lowest in the control group (5.2%). The test was positive in 52.7% of patients in the ASNHL group and 16.6% in the atypical CS group. The paired comparison analysis between groups showed that sensitivity of anti-Hsp70 in the typical CS group was significantly higher, as compared to the other three study groups.

Conclusions: Anti-Hsp70 antibodies can be considered a serological marker of “typical” CS. “Atypical” CS is conceivably a sort of “melting pot” of different forms of autoimmune diseases still characterized by ocular inflammation and sensorineural hearing loss but whose antigenic characteristics need to be further defined.

 Born in Czechoslovakia, psychiatrist Leo Eitinger (1912-1996) became internationally recognized for research on his fellow concentration camp inmates. He graduated as an MD in 1937, but being Jewish was prohibited from practicing as a doctor. When the Nazis moved into the area he was forced to flee to Norway, where in 1940 he was again deprived of his right to practice medicine. In 1942 he was arrested and deported to Auschwitz. There, as a physician inmate, he was able to help and in many cases save his fellow prisoners, not only with his medical skills but by falsifying prisoners' documents and hiding them from their Nazi captors. One of his patients was Elie Wiesel. Eitinger survived the camps but was forced to join a "death march." After the war he resumed medical practice in Norway, specializing in psychiatry. With his personal experience and knowledge of the suffering of camp survivors, he dedicated his life to studying the psychological effects of traumatic stress in different groups. Eitinger's academic contributions were crucial in the development of this area of research on the effects of excessive stress, laying the foundations for the definition of post-traumatic stress disorder and the post-concentration camp syndrome, thus facilitating recognition of the medical and psychological post-war conditions of the survivors and their resultant disability pensions.
