Background: Studies suggest that global semen quality is declining, but the debate remains open owing to geographic variation.

Objectives: To evaluate temporal trends of sperm parameters – namely concentration, motility and total motile sperm count – in sperm donated during the period 1995–2009.

Methods: In a retrospective longitudinal cohort study we analyzed the sperm count and motility of 2182 semen samples provided on a weekly basis by 58 young, healthy, fertile, university-educated, paid donors.

Results: Despite the lowering of criteria for sperm parameters satisfactory for donation that were implemented in 2004, 38% of applicants for sperm donation are now rejected based on semen quality as compared to a third of applicants 10–15 years ago (P < 0.001). If the old strict criteria were in place 88% of candidates would be rejected today (P < 0.0001). Over the study period, the average sperm parameters dropped from a concentration of 106 ± 25 million spermatozoa/ml with 79% ± 4.3% motility to 68 ± 14 million/ml with 66% ± 4.5% motile sperm (P < 0.0001, P < 0.0001, respectively). The total motile sperm count per ejaculate also decreased, from 66.4 ± 18.2 million to 48.7 ± 12 million (P < 0.005). When the previous criteria were implemented for the analysis of the latest group of sperm donors, only 18% of donors had an acceptable sperm quality, with an average concentration of 87 ± 12 million spermatozoa/ml, 73% ± 2.6% motile sperm and total motile sperm count of 53.1 ± 3.8 million per ejaculate – still significantly lower than 15 years ago (P = 0.01, P = 0.003, P = 0.058 respectively).

Conclusions: The rapid deterioration of sperm quality among fertile semen donors is alarming and may lead to cessation of sperm donation programs.

Background: Data on pediatric antiphospholipid syndrome (APS) are very sparse.

Objectives: To describe the main clinical characteristics, laboratory data and complications of pediatric APS patients, and to analyze the differences between primary APS and APS associated with systemic lupus erythematosus (SLE).

Methods: We retrospectively reviewed clinical and laboratory data of 32 children at “Federico Gomez,” the children’s hospital of México. Nineteen patients had SLE, 12 (37.5%) had primary APS and 1 (3%) had immune thrombocytopenic purpura. We collected information on sociodemographic variables, vaccinations, age at onset, and family history of rheumatic disease, hematological disorders, skin disorders and non-thrombotic neurological disorders. Immunological features included immunoglobulin (Ig) G and M aCl antibodies, IgG and IgM b2 glycoprotein I, lupus anticoagulant, anti-dsDNA and antinuclear antibodies.

Results: The patients included 24 females and 8 males. The most common thrombotic events were small vessel thrombosis (44%), venous thrombosis (28%) mainly deep venous thrombosis (DVT) in lower extremities, and arterial thrombosis (25%). The most common clinical non-thrombotic manifestations were hematological (53%) and neurological disorders (22%). There were no significant differences between groups with regard to the site of thrombosis, non-thrombotic clinical manifestations or laboratory features.

Conclusions: There were some important differences between the clinical manifestations of APS in children compared with adults, but we found no significant differences between patients with primary and APS associated with SLE. Larger studies in Latin American APS children are necessary to determine whether there are differences between ethnic groups.

Monogenic periodic fever syndromes are characterized by recurrent episodes of fever, accompanied by localized inflammatory manifestations. Among them, familial Mediterranean fever (FMF) is the most studied and is by far the most prevalent periodic fever syndrome in Israel. We present a diagnostic workup of a patient suffering from a periodic fever syndrome, initially thought to be FMF and characterized by attacks of fever, severe abdominal pain, a migratory erythematous rash and conjunctivitis. The development of periorbital edema presenting as diplopia led to consideration of tumor necrosis factor receptor-1-associated periodic syndrome (TRAPS). Genetic tests confirmed the diagnosis. This case should alert us that even in Israel, a patient with periodic fever, not fully consistent with the typical features of FMF, should be evaluated for other periodic fever syndromes.

Background: The increase in human immunodeficiency virus (HIV) among men who have sex with men (MSM) in Israel during the last decade raises concerns regarding other sexually transmitted diseases (STD) in MSM, which are yet undetermined.

Objectives: To evaluate the STD burden in MSM and heterosexuals visiting the Tel Aviv walk-in STD clinic.

Methods: Records of all male patients who attended the clinic once were reviewed to identify demographic characteristics, behavioural attributes, and test results.

Results: Between 2002 and 2008, 1064 MSM (22%) and 3755 heterosexuals (78%) visited the clinic once. Positivity rates in MSM for HIV, urethral Neisseria gonorrhoea and infectious syphilis were higher than in heterosexuals (2.5%, 2.5%. 0.7% vs. 0.6%, 1.3%, 0.3%, respectively), while urethral Chlamydia trachomatis was higher in heterosexuals than in MSM (2.7% and 1.4%, respectively). MSM tested in our clinic were younger than heterosexuals (P < 0.001), more commonly circumcised (P = 0.03) and Israeli-born (P < 0.001), used substances during sex (P = 0.04), and had prior STD (P < 0.001), a greater number of sexual partners (P < 0.001), and earlier sexual debut (P = 0.02). The final multivariate results for MSM to be diagnosed with HIV/STD were greater number of sexual contacts, previous diagnosis with STD, and infrequent use of condom during anal intercourse.

Conclusions: MSM visiting the Levinsky Clinic had higher rates of HIV/STD than heterosexual males, which correlated with their higher-risk behaviors. The unique characteristics of MSM found in our study, such as sex work, substance use, previous diagnosis of STD, multiple partners and inconsistent use of condom during anal sex should be addressed with innovative interventions to prevent STD/HIV in the gay community in Israel.

Background: Outbreaks of syphilis have been described among men who have sex with men (MSM) in many western urban communities in the last few years.

Objectives: To describe the first reported outbreak of syphilis among MSM in Israel within a decade of a constant increase in human immunodeficiency virus (HIV) prevalence.

Methods: All patients diagnosed with syphilis were contacted and asked about their sexual behavior, substance use and previous infections. All were tested for HIV and a phylogenetic analysis was performed. 

Results: A total of 23 (59%) of all 39 male patients diagnosed with primary or secondary syphilis between August 2008 and August 2009 were interviewed. All were MSM and performed anal intercourse, while 13 (55%) reported unprotected anal intercourse. Most participants (21, 91%) practiced unprotected oral intercourse. Nine participants (39%) reported unprotected oral intercourse while using condoms during anal intercourse. Ten participants (43%) reported sexual contacts while traveling abroad in the previous few months. Most participants (96%) were co-infected with HIV, and 15 (68%) were already aware of their HIV infection. Fifteen (66%) reported the use of recreational drugs, alcohol, or both before or during sex. No common source or core transmitters were identified.

Conclusions: This syphilis outbreak included MSM who were co-infected with HIV and were characterized by risky sexual behavior including multiple partners, unprotected anal intercourse and substance use. Future targeted interventions should focus on HIV-infected MSM for secondary prevention.

Hip arthroscopy is one of the most rapidly evolving arthroscopy techniques. It combines the benefits of a minimally invasive procedure and a short rehabilitation period. Improved instrumentation and technical skills have advanced our ability to accurately diagnose and treat various conditions. The role of this procedure continues to evolve with new indications that might change the outcome of degenerative joint disease of the hip joint. Hip arthroscopy is indicated for both traumatic and atraumatic intra and extra-articular conditions. Femoroacetabular impingement (FAI) is increasingly recognized as a disorder that can lead to progressive articular chondral and labral injury. A variety of arthroscopic techniques allows the treatment of labral and acetabular rim pathology as well as peripheral compartment femoral head-neck abnormalities. It is now recognized that labral tears that were traditionally treated with simple debridement are often associated with underlying FAI. Hip arthroscopy is also being used for surgery to the structures surrounding the hip as snapping hip syndromes, greater trochanteric pain syndrome, and arthroscopic repair of abductor tendon tears. Better understanding of the arthroscopic anatomy, improved operative techniques, lowered complication rate and objective outcome measuring tools will further define the optimal role of hip arthroscopy and improve its outcome.

Background: ‘Religious (halachic[1]) infertility’ results from precoital ovulation prior to immersion in a ritual bath (mikveh) 7 days after menstruation, as mandated by Jewish religious law. Previous authors recommended treatment with estradiol to postpone ovulation and enhance pregnancy rates.

Objectives: To evaluate the prevalence of halachic infertility in an ultra-Orthodox Jewish community, and assess the efficacy of estradiol treatment in postponing ovulation and increasing pregnancy rates.

Methods: We reviewed 88 cycles, of which 23 were control cycles and 65 estradiol-treated cycles, and analyzed the files of 23 women who were treated with 6 mg estradiol/day from day 1 for 5 days of the cycle.

Results: The prevalence of precoital ovulation in the infertile population was 21%. Most of the patients (94%) ovulated before day 13 of the cycle. A short follicular phase due to low ovarian reserve or thyroid endocrinopathy was noted in 12% of the patients. While 64% of the women reported consultation with a Rabbinate authority, 68% of the patients sought medical therapy. Estradiol postponed ovulation for at least one day in 89% of the treatment cycles. Ovulation post-mikveh occurred in 73% of estradiol-treated cycles. The pregnancy rate was 12.5% per cycle and the cumulative pregnancy rate 35% per woman. Half the patients reported spotting during estradiol-treated cycles, and this postponed coitus.

Conclusions: Precoital ovulation is a major reason for infertility among observant couples attending fertility clinics. Estradiol treatment is effective in delaying ovulation and restoring fecundity however, it causes some adverse effects that may decrease its effectiveness.

Background: Most reports in the medical literature on food allergy mortality are related to peanuts and tree nuts. There is limited knowledge regarding these reactions and often only a partial medical history is described.

Objective: To record and characterize all known cases of mortality due to food allergy in Israel occurring during the period 2004–2011.

Methods: All cases of food allergy-related mortality that were known to medical personnel or were published in the Israeli national communications media were investigated. We interviewed the parents and, when feasible, physicians who treated the final event.

Results: Four cases of food-related mortality were identified: three cases were due to cow’s milk and one to hazelnut. All were exposed to a hidden/non-obvious allergen. All four had a history of asthma but were not on controller medications, and all had experienced previous non-life threatening accidental reactions. Three of the four patients had not been evaluated by an allergist, nor were they prescribed injectable epinephrine. The one patient who had been prescribed injectable epinephrine did not use it during her fatal anaphylactic attack.

Conclusions: Fatal reactions to cow’s milk and hazelnut but not to peanut are the only reported food mortality cases in Israel. Although these patients had previous reactions following accidental exposures, none had experienced a life-threatening reaction. Patients at risk are not adequately evaluated by allergists, nor are they prescribed and instructed on the proper use of injectable epinephrine. Cow’s milk should be considered a potentially fatal allergen.

Background: Comorbid depression may play an important role in non-compliance with medical treatment among patients with chronic illnesses. Glaucoma is a potentially blinding chronic disease requiring life-long commitment to medical therapy. Patient's failure to adhere to anti-glaucoma treatment may lead to disease progression and visual loss.

Objectives: To assess the prevalence of depressive symptoms in glaucoma patients and the association between these symptoms and non-compliance with anti-glaucoma therapy.

Methods: This was a cross-sectional observational study. Compliance with pharmacotherapy was assessed with the Morisky Medication Adherence questionnaire (eight items). Screening for depression was performed by means of the CES-D scale (Center for Epidemiologic Studies Depression scale). The association between depression and compliance rates was analyzed.

Results: The study group comprised 76 glaucoma patients; 19.7% of the subjects were classified as "non-compliant" (Morisky cutoff < 10) and 21.1% suffered from depression (CES-D cutoff ≥ 16). We found a similar level of non-compliance when comparing depressed with non-depressed glaucoma patients. However, a significant correlation was observed between the level of depression and the level of non-compliance (P = 0.04).

Conclusions: Our study revealed a similar rate of depression in glaucoma patients and the general Israeli population. The presence of depression was not associated with the presence of non-compliance, yet the level of depression was associated with the level of non-compliance.

Background: Myotonic dystrophy type 2 (DM2) is an autosomal dominant, multisystem disorder caused by a CCTG tetranucleotide repeat expansion located in intron 1 of the zinc finger protein 9 gene (ZNF9 gene) on chromosome 3q 21.3.

Objectives: To describe the clinical, electrophysiologic and pathologic findings in patients with myotonic dystrophy 2.

Methods: We evaluated 10 patients genetically, clinically and electrophysiologically during the years 2007 to 2008.

Results: All patients were of Jewish European ancestry. Among affected individuals, eight patients had symptoms of proximal muscle weakness, two had muscle pain, and two exhibited myotonia. On physical examination six patients had severe weakness of hip flexor muscles. Seven individuals underwent cataract surgery, and cardiac involvement was seen in one case. On the initial electromyographic (EMG) examination five patients demonstrated myotonic discharges; repeated studies showed these discharges in nine cases. Six muscle biopsies showed non-specific pathological changes. Seven patients had an affected first-degree relative with either a diagnosed or an undiagnosed muscular disorder, consistent with an autosomal dominant trait.

Conclusions: DM2 may often present with proximal muscle weakness without myotonia. EMG may initially fail to show myotonic discharges, but these discharges may eventually show in most cases on repeated EMG. Thus, DM2 may be underdiagnosed and should be included in the differential diagnosis of adult patients of Jewish European ancestry presenting with proximal lower limb weakness.
