Background: The co-morbidity of human immunodeficiency virus and other sexually transmitted diseases in Israel has not been established. 

Objectives: To compare the prevalence of STDs [1]among HIV[2]-positive patients to HIV-negative patients visiting an STD clinic in northern Israel. 

Methods: Between December 2000 and December 2001, 176 HIV-positive individuals (53% males) were screened and compared to 200 HIV-seronegative individuals (76% males). Demographics, symptomatology and risk factors were obtained via questionnaire. First-void urine samples were tested for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae. Serum was tested for type-specific herpes simplex virus-2, hepatitis B and syphilis. 

Results: Relative to the seronegative STD patients, HIV-positive patients exhibited significantly greater risk-reducing sexual behaviors such as consistent condom use [29/86 (33.7%) vs. 16/187 (8.6%), P < 0.001], and abstinence in the previous 6 months [43/125 (34%) vs. 7/185 (3.8%), P < 0.001]. Nevertheless, STD prevalence was higher among HIV-positive than HIV-negative patients (79.5% vs. 37.5%, P < 0.001). HSV[3]-2, syphilis and HBV[4] were more common among HIV-positive than HIV-negative patients [120/175 (68.8%)] vs. 18/200 (9%), P < 0.001)], [43/161 (26.7%) vs. 0%, P < 0.001)], [13/171 (7.6%) vs. 3/200 (1.5%), P < 0.01)], respectively. In contrast, Chlamydia and gonorrhea were more commonly found in HIV-negative patients than HIV-positive patients [3/176 (1.7%) vs.13/200 (6.5%), P < 0.05] vs. [0% vs.5/200 (2.5%), P < 0.05], respectively. 

Conclusion: Despite the low risk sexual behavior of Israeli HIV patients, they had a high prevalence of chronic STDs (e.g., HSV-2, HBV and syphilis). The lower prevalence of Chlamydia and gonorrhea among HIV-immunosuppressed patients may be attributed to routine antibiotic prophylaxis against opportunistic infections. Nevertheless, as advocated by international health organizations, it appears prudent to recommend the routine screening of these asymptomatic HIV-positive patients for STD pathogens. 

Background: Persistent creatine kinase elevation is occasionally encountered in subjects without any clinical manifestation of a neuromuscular disorder or any condition known to be associated with increased serum CK[1] levels. It is still unresolved whether extensive investigations and specifically a muscle biopsy should be performed in clinically normal individuals with elevated CK levels.

Objective: To study the muscle pathology of patients with asymptomatic or minimally symptomatic hyperCKemia.

Methods: The clinical and laboratory data of patients with persistent hyperCKemia and normal neurologic examination were reviewed and their muscle biopsies evaluated.

Results: The study group included 40 patients aged 7–67 years; the male to female ratio was 3:1. Nineteen patients were completely asymptomatic, 20 had mild non-specific myalgia, and 1 had muscle cramps. Electromyography was performed in 27 patients and showed myopathic changes in 7 (26%). Abnormal muscle biopsy findings (e.g., increased variation in fiber size, increased number of central nuclei and occasional degenerating fibers) were detected in 22 of the 40 patients (55%). No fat or glycogen accumulation was detected. Immunohistochemistry demonstrated abnormal dystrophin staining in 3 patients (8%), resembling the pathologic changes of Becker muscular dystrophy. No abnormal findings were detected on immunohistochemical staining for merosin, dysferlin, caveolin 3, or alpha and gamma sarcoglycans. The EMG[2] findings did not correlate with the pathologic findings.

Conclusions: Abnormal muscle biopsies were found in 55% of patients with asymptomatic or minimally symptomatic hyperCKemia. Specific diagnosis of muscular dystrophy, however, was possible in only 8% of the patients.

Objectives: To examine whether hostility, anxiety and autobiographical memory (a correlate of depression) are associated with IIH[1].

Methods: Using a case-control cross sectional design, 20 patients with IIH were compared with 9 healthy controls of similar age, weight and height, and 11 headache controls. Patients were assessed for hostility and anxiety. The Autobiographical Memory Test was used to assess episodic memories.

Results: The IIH group reported significantly more anxiety and more general episodic memories than the healthy controls, but not the headache control group. The headache control patients reported more general memories than did the healthy controls.

Conclusions: Patients with headaches, whether of general origin or related to IIH, have a poor psychosocial profile. While the study design does not permit any conclusions regarding causality, our results support the need to consider psychological factors in evaluating and treating IIH and headache patients.

Background: A major psychological sequel of terrorist attacks is post-traumatic stress disorder. The relation between certain psychological factors specific to terrorist attacks (e.g., perceived control attributed to oneself/to the military, anticipated duration of terrorism) and PTSD[1] symptoms have not been examined.

Objective: To examine the prevalence, correlates and moderators of PTSD-like symptoms following terrorist attacks in Israel.

Methods: Soon after a long wave of terrorist attacks in Israel in 2002, a convenience sample of 149 Israelis from five cities was assessed for terrorist attack exposure, perceived control, control attributed to the government/military, anticipated duration of the terrorism wave (predictability), and frequency of listening to the news. PTSD-like symptoms were assessed with a brief self-report scale.

Results: We found that 15.4% of the sample was directly exposed to a terrorist attack and 36.5% knew someone close who had been exposed to an attack. “Clinically significant” PTSD-like symptoms were reported by 10.1% of the sample. Correlates of PTSD-like symptoms were: perceived control in men, government control, and education in women (all inversely correlated to PTSD symptoms), and news-listening frequency in women (positively correlated to PTSD symptoms). PTSD-like symptoms were attenuated by the ability to predict the duration of the terrorism wave only in citizens exposed to an attack, and by perceived government control only among citizens listening infrequently to the news.

Conclusions: This study revealed that approximately 10% of Israelis in our sample had relatively frequent PTSD-like symptoms. Correlates of PTSD-like symptoms differed between men and women, and moderator effects were found. These findings reveal additional moderators that may have implications for treating PTSD following terrorist attacks.

Background: Eyes scheduled for posterior segment surgery may have cataract, which obscures the visualization of the retina. Surgery may be carried out either by a two-step procedure: i.e., removal of the cataract followed later by posterior segment surgery; or it may be done in a single session: i.e., combined surgery of both the anterior and posterior segments.

Objective: To evaluate the outcomes of combined surgery by phacoemulsification and vitrectomy.

Methods: We retrospectively reviewed the records of 42 patients with coexisting cataract and vitreoretinal disease who underwent combined surgery by phacoemulsification and pars plana vitrectomy at one session.

Results: Indications for surgery were vitreous hemorrhage in 71.4%, retinal detachment in 11.9%, macular hole in 11.9%, and epiretinal membrane in 4.8%. There were no significant intraoperative complications.The main early postsurgical complications were fibrinous formation in 11.9%, elevated intraocular pressure in 23.8%, and recurrent vitreous hemorrhage in 9.5%. There were a few late complications related to phacoemulsification: posterior synechia in 9.5%, posterior capsular opacification in 7.1%, and dislocating intraocular lens in 4.8%. Recurrent retinal detachment occurred in five eyes and rubeoisis iridis in one. Visual acuity was improved in 85.8%, stable in 7.1% and worse in 7.1%.

Conclusions: Phacoemulsification performed at the time of posterior segment surgery enables good visualization during the vitrectomy, facilitates surgery, and is associated with only minor complications. In cases with cataract and vitreoretinal diseases, combined surgery by phacoemulsification and vitrectomy in one session may be considered.
 

Background: Increased serum potassium and intraventricular hemorrhage occur frequently in preterm infants.

Objective: To retrospectively analyze data obtained on infants with severe IVH[1] in relation to blood K⁺ concentrations.

Methods: We identified all patients with severe IVH born between July 1997 and July 2000. Each patient was pair-matched with a control infant of the same gestational age (±1 week) without IVH in terms of head ultrasound findings on day 5, and whole blood K⁺ on days 3–5.

Results: There were 24 infants in each group. The IVH group had significantly lower 1 minute Apgar scores and pH and higher blood K⁺ than the control group. Blood pH and K⁺ were inversely correlated. Stepwise regression analysis, taking into account blood pH and 1 minute Apgar score, showed a correlation only between blood K⁺ and IVH status.

Conclusions: Severe IVH is significantly associated with higher blood K⁺ concentrations. A causal relationship cannot be ascertained at this point.
