Objectives: To determine the prevalence of different pathogens in patients presenting to our sexually transmitted disease clinic with hematospermia.

Methods: Between January 1999 and January 2000, 16 patients presented to our STD[1] clinic with hematospermia after other non-infectious pathologies had been excluded by a referring physician. After obtaining informed consent, subjects completed a questionnaire addressing symptoms and sexual behavior. First void urine samples, as well as genitourinary and serum specimens were tested for Chlamydia trachomatis, Ureaplasma urealyticum and Herpes simplex virus. Standard bacterial cultures were also performed.

Results: Laboratory testing detected a pathogen in 12 of the 16 males presenting with hematospermia. The sexually transmitted pathogens detected were Herpes simplex virus in 5 patients (42%), Chlamydia trachomatis in 4 (33%), Enterococcus fecalis in 2 (17%), and Ureaplasma urealyticum in 1 (8%). In all cases in which a pathogen was identified, the appropriate antimicrobial agent was administered. Symptoms resolved for each patient following antimicrobial therapy. During a 1 year follow-up, all 12 patients remained free of disease.

Conclusions: Recent advances in microbiologic diagnostic techniques have facilitated the detection of pathogens in patients with hematospermia, thereby enhancing the efficacy of treatment.

Objectives: To define the incidence of congenital CMV infection in two different subpopulations, as a model for the entire population of Israel.

Methods: Urine specimens were randomly collected from 2,000 newborns in Shaare Zedek Medical Center, Jerusalem, and HaEmek Medical Center, Afula (1,000 specimens each). These hospitals have many characteristic differences, presumably representing the diverse population of Israel. Urine specimens were subjected to a CMV PCR[2] reaction and positive specimens were validated by urine viral culture. Maternal seroprevalence was determined in a representative sample of the mothers in each hospital. Epidemiologic characteristics of the mothers were extracted from hospital records and compared.

Results: The population in Shaare Zedek Medical Center was mostly Jewish (95.8%) and urban (87.0%), as compared to that of HaEmek Medical Center (49.2% and 61.0%, respectively, P < 0.01). Nevertheless, CMV seroprevalence was similar: 81.5% and 85%, respectively. Ten (1.0%) and 4 (0.4%) newborns, respectively, were found to have congenital CMV infection (not significant).

Conclusions: The combined incidence of congenital CMV infection in the study population was 0.7% (95% confidence interval 0.3–1.0%). If this rate is extrapolated to the entire population of Israel, then a total of 945 cases of congenital CMV can be expected among the 135,000 annual deliveries. A nationwide screening program for congenital CMV should be considered.

Objective: To identify risk factors and associated conditions that may cause TdP[1] in patients on chronic amiodarone treatment.

Methods: We reviewed the data of six consecutive patients on chronic amiodarone treatment who were admitted to the intensive cardiac care unit due to syncope and TdP.

Results: The patients’ median age was 73.5 years, and five were women. Concomitantly, loratadine was given to two patients and trazodone to one patient. Associated and attributing conditions to the development of TdP were hypokalemia in three patients, drug-induced bradycardia in one and reduced left ventricular function in four.

Conclusions: TdP associated with chronic amiodarone treatment may occur when amiodarone is co-administered with drugs that may potentially prolong QT interval. Additional risk factors for amiodarone-associated TdP include female gender, hypokalemia, reduced left ventricular function and bradycardia.

Objectives: To report on our initial experience over a 7 month period with an eight-bed mechanical ventilation weaning unit.

Methods: Sixty-nine patients requiring MV[1] for >10 days were admitted to the unit (nurse:patient ratio 1:4). Data collected included reason for MV, duration of hospital stay, and MVWU[2] course. Outcome results (successful weaning and mortality) were compared to those in historic controls (patients ventilated in the general wards over a 4 month period prior to the MVWU; n = 100).

Results: The mean age of the patients was 68 ± 16.6 years and hospital stay prior to MVWU admission 28.6 ± 24.2 days (range 10–72). The main reasons for MV included acute exacerbation of chronic obstructive pulmonary disease (31%) and recent pneumonia (28%). Mean MVWU stay was 13.5 ± 15.7 days (range 1–72 days). Thirty-four patients (49%) underwent tracheostomy. Fourteen patients required admission to the ICU[3] due to deterioration in their status. Twenty-nine patients (42%) were successfully weaned and discharged to the wards. A further 20 patients were transferred to the chronic ventilation unit of a regional geriatric rehabilitation hospital, where 5 were subsequently weaned and 15 required prolonged ventilation. Compared to controls (matched for age and reason for mechanical ventilation), more MVWU patients underwent successful weaning (49% vs. 12%, P < 0.001) and their mortality rate (n = 12) was significantly lower (17% vs. 88%, P < 0.001).

Conclusion: The higher level of care possible in a MVWU may result in a significantly improved rate of weaning and lower mortality. The assessment of long-term outcome in patients discharged to pulmonary rehabilitation centers requires further investigation.

Objective: To describe the experience of our CF[1] center in the management of CF pregnant woman from 1977 to 2004.

Methods: We analyzed 27 years of records (1977–2004) of the national CF registry of all CF women who wished to conceive and became pregnant.

Results: Eight CF women (mean age 24 ± 4.5 years) who wished to conceive had 11 pregnancies and delivered 12 neonates. The pregestational results of forced expiratory volume per 1 second varied significantly among patients (59 ± 23%), yet most (10/11) stayed stable throughout the pregnancy course. Maternal deterioration in CF condition occurred in only one mother, necessitating cesarean section. In 9 of the 11 pregnancies the women were pancreatic-insufficient. Of the 11 pregnancies, 2 CF women had diabetes mellitus and 3 developed gestational diabetes. One pregnancy occurred in a mother with a transplanted lung. Of the 12 neonates, 3 were preterm and one was born with esophageal atresia. No miscarriages, terminations or neonatal mortalities occurred. Although most of the CF mothers had FEV_1[2] below 55% before pregnancy, the maternal and neonatal outcome was favorable and lung function tests generally remained stable.

Conclusions: We conclude that pregnancy in CF is feasible with a positive maternal and neonatal outcome. Early participation of the CF physician in the wish of the CF woman to reproduce is required. The integration of an intensive multidisciplinary approach during pregnancy, which includes close follow-up of maternal and fetal condition by the various specialists, should ensure an optimal outcome.

Background: Hypertension is considered resistant if blood pressure cannot be reduced to <140/90 mmHg with an appropriate triple-drug regimen, including an oral diuretic, with all agents administered at maximal dosages. This definition has evolved with the development of new therapies and evidence-based data supporting treatment to lower BP[1] goals.

Objective: To assess whether vitamin C and atorvastatin improve endothelial function and blood pressure control in subjects with resistant arterial hypertension and dyslipidemia.

Methods: Forty-eight hyperlipidemic subjects with RH[2] (office systolic BP >140 mmHg and/or office diastolic BP >90 mm/Hg notwithstanding antihypertensive treatment with three medications in maximal doses) were randomized into three groups to receive additional medication for 8 weeks. Group VTC (n = 17) – mean 24 hour SBP[3] 150.6 ± 5.2 mmHg, DBP[4] 86.1 ± 3.3 mmHg, low density lipoprotein 158.1 ± 24.5 mg/dl) – received vitamin C 500 mg per day; Group ATR (n = 15) – mean 24 hour SBP 153.1 ± 4.8 mmHg, DBP 87.1 ± 6.7 mmHg, LDL[5] 162.6 ± 13.6 mg/dl) – received atorvastatin 20 mg/day; and Group PLA (n = 16) – mean 24 hour SBP 151.1 ± 7.4 mmHg, DBP 84.8 ± 5.9 mmHg, LDL 156.7 ± 26.1 mg/dl – received a placebo. High resolution ultrasound was used to calculate brachial artery flow-mediated dilation, and 24 hour ambulatory BP monitoring was performed at study entry and after 8 weeks.

Results: In the ATR group there were significant reductions of SBP (DSBP1-2: 13.7 ± 5.6 mmHg, P < 0.001), DBP (DDBP1-2: 7.8 ± 5.7 mmHg, P < 0.01), LDL (DLDL1-2: 67.7 ± 28.3 mg/dl, P < 0.001) and improvement of brachial artery FMD[6] (DFMD2-1: 4.2 ± 2.6%). No significant changes in BP, LDL and FMD were observed in the other two groups.

Conclusions: In subjects with RH and dyslipidemia, atorvastatin 20 mg/day compared to vitamin C 500 mg/day may help to achieve better BP control and improve endothelial function in a finite period. A larger trial is needed to assess the drug's efficacy in this population for longer periods.

Background: Bladder exstrophy is a severe congenital defect that requires a multidisciplinary treatment approach. Soft tissue repair may be successful during the first few days after birth but a combination of pelvic osteotomies and bladder reconstruction is necessary later in life. The combination of externally fixed anterior and posterior osteotomies has biomechanical advantages over previous techniques for achieving primary bladder closure.

Objectives: To describe our experience with a combined vertical and horizontal pelvic osteotomy approach for the repair of bladder exstrophy.

Methods: Four children underwent bladder exstrophy closure; the mean age at surgery was 19 months (range 9–33 months)... We stabilized the osteotomies with a small Synthes AO external fixator, 4.0 mm rod diameter.

Results: All four patients had successful bladder repair with no dehiscence; two of them achieved partial continence, and bladder neck reconstruction is planned for the other two. Three of the four patients sustained neurologic injury; two completely recovered, and the third continues to suffer from right drop foot. The average follow-up was 39 months (range 10–60 months).

Conclusions: Vertical and horizontal pelvic osteotomies stabilized by external fixator and bladder repair is an effective treatment for bladder exstrophy.

The prevalence of obesity worldwide has risen sharply during the last four decades. The etiology of obesity is complex and includes a host of genetic influences in addition to the overconsumption of energy coupled with a sedentary lifestyle. Obesity is known to cause or exacerbate many co-morbid conditions such as diabetes, hypertension, dyslipidemia, coronary heart disease, stroke, certain cancers, arthritis and obstructive sleep apnea. Modest weight losses of 5–10% of actual weight are related to significant improvements in co-morbid conditions, but unfortunately the rate of recidivism with short-term therapy for obesity is high. The recent recognition of obesity as a chronic disease that should be treated with long-term programs and possibly with polypharmacy, and the alarming increase in its prevalence, have prompted extensive research and the development of new pharmacotherapy.
