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.

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: Proximal hip fractures in the elderly are common and have serious implications for health resources. Researching the timing of these fractures could contribute to diverting resources towards peaks in incidence and investing in prevention at certain times.

Objectives: To examine the effect of seasonality, weather and holidays on hip fracture incidence in older adults. The study population comprised 2050 patients aged 65 years or more who sustained a proximal hip fracture.

Methods: The computerized files of the patients were reviewed for trends in incidence by season, precipitation, minimum and maximum temperatures, day of the week, and certain Jewish festivals.

Results: Hip fractures were more likely to occur in the winter than in the summer (P < 0.0001). Factors that significantly correlated with hip fracture were the maximum daily temperature (r = -0.746, P = 0.005) followed by the minimum daily temperature (r = -0.740, P = 0.006) and precipitation (r = 0.329, P = 0.02). There were fewer fractures on Saturdays (the Sabbath) as compared to other days of the week (P = 0.045). Researching the incidence on Jewish festivals, we found an elevated incidence on Passover (P < 0.0001) and a reduced incidence on the Day of Atonement (Yom Kippur) (P = 0.013).

Conclusions: In older people there is an elevated incidence of proximal hip fractures during the winter and on the Jewish festivals. On weekends and on the Day of Atonement the incidence of proximal hip fractures was reduced.

 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.

 Reinhard Heydrich, architect of the “Final solution of the Jewish problem,” had a meteoric career in the SS. He organized the Wannsee Conference and created the SS killing squads. Under his leadership as Reich Protector of Bohemia and Moravia, the suppression of the Czech community was brutal. An attempt on his life in Prague was unsuccessful but it left him severely injured and he died eight days later. Reviewing the available information on his hospital treatment and the autopsy report, it is suggested that Heydrich received substandard medical treatment, quite likely a result of political interference from rival members of the SS hierarchy.

 Background: Human amnion membrane (HAM) was suggested to be a superior antigenic substrate for immunoblotting in detecting autoantibodies of autoimmune bullous skin diseases.

Objectives: To determine the properties of HAM as an antigenic substrate for the detection of autoantibodies in pemphigus vulgaris and bullous pemphigoid.

Methods: Immunomapping and tandem liquid chromatography mass spectrometry were used to delineate the antigenic structure of HAM in 25 pemphigus patients, 41 pemphigoid patients, and 36 controls. Immunoblotting and indirect immunofluorescence were used to study the diagnostic utility of HAM, and the results were compared to those of indirect immunofluorescence on monkey esophagus, immunoblotting using normal human skin, and enzyme-linked immunosorbent assay (ELISA).

Results: Immunomapping demonstrated the presence of all the antigens known to be targeted in autoimmune bullous skin diseases, in both normal human skin and HAM, except for the absence of BP230, and low threshold levels of Dsg1, Dsg3 and Dsc3 in HAM. HAM indirect immunofluorescence demonstrated anti-basement membrane zone antibodies in 48.7% of the pemphigoid patients, and anti-intercellular space antibodies in 72.0% of the pemphigus patients. HAM immunoblotting did not demonstrate anti-BP230 antibodies, but detected anti-BP180 antibodies in 53.6% of the pemphigoid patients. It did not demonstrate anti-Dsg1 and/or anti-Dsg3 antibodies in any of the pemphigus patients. These results were inferior to those of ELISA and monkey esophagus indirect immunofluorescence.

Conclusions: Compared to other studied methods, HAM does not offer advantages in detecting autoantibodies in bullous pemphigoid and pemphigus vulgaris.

 Background: Acute lymphocytic leukemia (ALL) is a rare disease with a poor outcome in adults. Over the years different protocols have been developed with the aim of improving the outcome. The German study group protocols (GMALL), which are the most frequently used in our institutions, changed significantly between the periods 1989–93 and 1999–2003.

Objectives: To investigate whether the change in protocols over the years resulted in an outcome difference at two hospitals in Israel.

Methods: We thoroughly reviewed the records of 153 patients from Sheba Medical Center and Soroka Medical Center, of whom 106 comprised the study group. The patients were divided into two groups according to the treatment protocol used: 40 patients with the 1989/93 protocol and 66 with the 1999/2003 protocol. Outcome was analyzed for the two groups.

Results: We found a significant difference in disease-free survival (DFS) between the two groups for B cell-ALL (B-ALL) patients who achieved complete remission after induction. There was no difference in overall survival. We did not find any difference in outcome for T cell-ALL patients or for CD20-positive patients.

Conclusions: In our retrospective analysis, GMALL 99/2003 led to a better DFS for B-ALL patients who were in complete remission after induction. This is possibly related to the differences in medications between the protocols, but may also be due to better supportive care. Despite the proven advantage of the newer protocols regarding overall survival, in our experience there was no other significant difference between the two regimens.
