Background: Management of patients with hereditary angioedema with C1-inhibitor deficiency (C1-INH-HAE) is evolving worldwide. Evaluating the Israeli experience may provide valuable insights.

Objectives: To compare demographics and icatibant treatment patterns and outcomes in patients with C1-INH-HAE enrolled in the Icatibant Outcome Survey (IOS) in Israel with those in other countries.

Methods: The IOS is an ongoing observational study that prospectively monitors real-world icatibant safety/tolerability and treatment outcomes.

Results: By July 2016, 58 patients from Israel and 594 patients from other countries were enrolled. Median age at diagnosis (16.7 vs. 21.3 years, P = 0.036) and median delay between symptom onset and diagnosis (0.8 vs. 6.6 years, P = 0.025) were lower in Israel compared with other countries, respectively. Differences in attack severity were not significant (P = 0.156); however, during follow-up, Israeli patients were less likely to miss > 7 days of work/school due to C1-INH-HAE-related complications (P = 0.007). A trend was also shown in Israel for earlier time to treatment (median 0.5 vs. 1.3 hours, P = 0.076), attack duration was shorter (median 5.0 vs. 9.0 hours, P = 0.026), and patients more often self-administered icatibant (97.2% vs. 87.5%, P = 0.003), respectively. However, Israeli patients were less likely to treat attacks (P = 0.036). Whereas patients in Israel reported exclusive use of danazol for long-term prophylaxis, those in other countries used various agents, including C1-INH.

Conclusions: Recognition of C1-INH-HAE and timeliness of icatibant treatment appear more favorable, and attack duration shorter, in Israel compared with other countries.

 Background: Eye injuries are common in sports. Sports-related eye injuries have the potential for major morbidity.

Objectives: To investigate the occurrence and to classify sport-related eye trauma in northern Israel.

Methods: We analyzed the records of the ophthalmology emergency department for the years 2007–2011 and classified the admissions according to type, severity of injury and demographic data.

Results: In 2% of the patients the injuries occurred during a sport activity. Most of the injuries occurred during soccer, basketball or school sport activity (74%). The majority of patients were young males.

Conclusions: Most sports-related eye injuries can be prevented with adequate eye protection.

Background: Cancer is a leading cause of mortality worldwide. The most effective way to combat cancer is by prevention and early detection.

Objectives: To evaluate the outcome of screening an asymptomatic population for the presence of benign and neoplastic lesions.

Methods: Routine screening tests for prevention and/or early detection of 11 common cancers were conducted in 300 consecutive asymptomatic, apparently healthy adults, aged 25–77 years. Other tests were performed as indicated.

Results: Malignant and benign lesions were found in 3.3% and 5% of the screenees, respectively, compared to 1.7% in the general population. The most common lesions were in the gastrointestinal tract followed by skin, urogenital tract and breast. Advanced age and a family history of a malignancy were associated with increased risk for cancer with an odds ratio of 9 and 3.5, respectively (95% confidence interval 1.1–71 and 0.9–13, respectively). Moreover, high serum C-reactive protein levels and polymorphisms in the APC and CD24 genes indicated high cancer risk. When two of the polymorphisms existed in an individual, the risk for a malignant lesion was extremely high (23.1%; OR[1] 14, 95% CI[2] 2.5–78).

Conclusions: Screening asymptomatic subjects identifies a significant number of neoplastic lesions at an early stage. Incorporating data on genetic polymorphisms in the APC and CD24 genes can further identify individuals who are at increased risk for cancer. Cancer can be prevented and/or diagnosed at an early stage using the screening facilities of a multidisciplinary outpatient clinic.

Background: The trefoils factor family is a relatively new family of peptides. Their abundant expression in the epithelial cells of the gastrointestinal tract in the normal physiological state and in various ulcerative conditions suggests an important role in mucosal defense and repair. Infection with Helicobacter pylori interferes with normal mucosal activity.

Objectives: To investigate whether H. pylori infection alters the expression of trefoils TFF1[1] and TFF2 in the gastric mucosa of patients with H. pylori-associated chronic active gastritis, positive or negative for the CagA strain.

Methods: During investigation for dyspepsia, gastric biopsies and blood samples were obtained from patients who underwent upper gastrointestinal endoscopy. Rapid urease testing, histology for determination of H. pylori-associated CAG[2] and Western analysis for TFF1 and TFF2 expression with antisera were performed. CagA state was determined using a commercial kit.

Results: TFF2 expression was significantly reduced in both groups of patients with H. pylori-associated CAG compared to healthy patients without H. pylori infection, particularly in CagA-positive patients. TFF1 expression showed a tendency of reduction (not significant) in this group only.

Conclusions: These results suggest that H. pylori-associated CAG has a deleterious effect on the expression of TFF2 in the gastric antrum. This reduced expression may contribute to the damage induced to the gastric mucosa by H. pylori.

Hereditary angioedema is a rare genetic disorder, manifested by recurrent edema leading to disfigurement, organ dysfunction and life-threatening respiratory impairment that may become fatal. The hallmark of HAE is a C1 esterase inhibitor deficiency, but recent evidence points at bradykinin as the main mediator that causes hyperpermeability of small vasculature, leading to accumulation of edema fluid. Current therapeutic options for HAE[1] are limited, and consist of drugs, replacement therapy, and supportive treatment. In view of many disadvantages of the current therapeutic modalities new approaches to the treatment of HAE are now being offered. This review summarizes our experience with a new line of medications developed for the treatment of acute exacerbations and prophylaxis of HAE – icatibant: bradykinin receptor antagonist, ecallantide: kallikrein inhibitor, and two C1 INH[2] preparations: Berinert-P, human plasma-derived concentrate, and Rhucin: novel recombinant C1-INH produced in transgenic rabbits. Preliminary results of these studies are encouraging and may bring new hope to the patients with this distressing condition. The exact number of HAE patients in Israel is unknown and because patients are treated individually and comprehensive laboratory assessment is partial, many cases might be missed or not treated according to accepted guidelines. We offer a new specialty center for HAE patients, addressing the medical and psychosocial needs of patients and their families.

 Background: Postpartum depression is a well-known phenomenon that occurs in about 10% of births and affects the quality of life of the mother as well as the family. As in other cases of depression, under-diagnosis of PPD[1] may keep patients from getting proper care and increase their physical and emotional distress.

Objectives: To identify patients with PPD and to describe their consultation patterns with primary care physicians for themselves and their babies.

Methods: Using a telephone survey and the Edinburgh Postnatal Depression Scale questionnaire we identified PPD in a sample of women who gave birth in HaEmek Medical Center. We also assessed the extent to which the women consulted with family physicians, gynecologists and/or pediatricians.

Results: The survey included 574 women, of whom 9.9% were diagnosed with PPD. There was a higher rate of PPD among Arab compared to Jewish women, among women with a prior history of depression, among women whose pregnancy was unplanned, among those who described the course of pregnancy as “difficult,” and among women who described their general health as “not good.” Women with PPD consulted more with family physicians and pediatricians. The reasons for the consultations are physical and emotional. There were cases of somatization manifested directly by the mother or indirectly through the baby.

Conclusions: Women with PPD have higher consultation rates than those without. By asking a few simple questions it is possible to identify a significant proportion of women with PPD.

Background: Some studies have indicated a possible link between cigarette smoking and hearing loss.

Objectives: To analyze the association between smoking and hearing loss, other than that induced by noise, and to characterize the type of HL impairment found in smokers.

Methods: We conducted a retrospective cross-sectional study in 13,308 men aged 20±68 (median 34.6 years) who underwent a hearing test as part of a routine periodic examination. For each subject, age, smoking status (current, past or non-smokers) and number of cigarettes per day were noted and a hearing test was performed. The test was performed in a sealed, soundproof room by an experienced audiologist and included pure tone audiometry of 250±8,000 Hz. The audiograms were analyzed and subjects were accordingly divided into two groups: those with HL and at least one of the following impairments in at least one ear: sensorineural, conductive or mixed; and those with no hearing loss (control). Audiograms showing HL typical to noise exposure were excluded.

Results: The prevalence of any type of HL among subjects <35 years was 4.5%, compared to 10.5% among those >35 years (P < 0.0001). A significantly higher incidence of any type of HL was found in current (11.8%) and past smokers (11.7%) than in non-smokers (8.1%) (P < 0.0001). The risk increment of the smoking status for developing HL among subjects under age 35 was 43%, and 17% among those above 35 years. Both mild, flat, sensorineural impairment and conductive impairment were found to be associated particularly with smoking (odds ratio 2.2 and 1.9, respectively).

Conclusions: The incidence of HL unrelated to noise exposure is higher in smokers than in non-smokers, and in young adults the effect is greater.
