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.

Background: An organ sharing system should achieve fairness and optimal graft longevity. Balancing between social and utilitarian considerations is a sensitive ethical, public and medical issue that requires a means to examine the consequences of any allocation policy or planned changes thereof.

Objective: To evaluate the performance and applicability of a computerized simulation model by examining the impact of two opposing organ allocation policies (social or utilitarian) on predicted organ distribution regarding age, waiting time, recipient sensitization measured by panel reactive antibody level and overall donor-recipient tissue matching (measured by the number of HLA antigen mismatches).

Methods: Using a computerized simulation model, virtual donors and recipients were emulated and organs were allocated according to either social algorithms or utilitarian policies. The resulting number of HLA mismatches, PRA[1], age, and waiting time distributions were compared between allocation strategies.

Results: Simulating allocation of 7,000 organs to 17,000 candidate recipients and implementing social policies yielded donor-recipient compatibility comparable to utilitarian policies (0–1 mm: 19.4% vs. 28%) while allocating 66.7% of organs to long waiters (>48 months).

Conclusion: This computerized simulation model is a valuable tool for decision-makers establishing or modifying organ allocation policies.

Background: Primary hyperparathyroidism in elderly patients is usually associated with additional co-morbidity that increases operative risk, and thus many geriatric patients are denied the benefit of surgery for a single parathyroid adenoma.

Objectives:  To evaluate the safety and efficacy of accurate single photon emission computed tomography sestamibi scintigraphy, enabling precise localization of a single adenoma, in the geriatric population

Methods: Twenty-two patients aged 70 years and over with biochemically proven PHPT[1] and with a single parathyroid adenoma identified by localization studies (sestamibi SPECT[2] scan and ultrasonography) underwent 23 operations over 29 months (out of a total of 140 patients operated upon during the same period). Immediate preoperative sestamibi scintigraphy and marking of focal adenoma uptake followed by intraoperative hand-held gamma probe were used for the removal of the parathyroid adenoma by unilateral minimal access surgery. Associated major co-morbid conditions and pre- and postoperative calcium, phosphorus and parathormone levels were recorded. Indications for surgery were listed and operative and postoperative complications were noted. The patients were followed for a mean period of 17.7 months using the same parameters.

Results: The 22 patients with PHPT had a mean age of 76.3 ± 5.9 years (range 70–88 years)  and a female to male ratio of 13:9. Associated co-morbidity included ischemic heart disease (n=15), hypertension (n=22), non-insulin-dependent diabetes mellitus (n=9), chronic obstructive pulmonary disease (n=3), and previous neck surgery (n=3). Mean preoperative serum calcium, phosphorous and PTH[3] were 11.7 ± 1.3 mg/dl, 2.5 ± 0.5 mg/dl and 160.9 ± 75.4 pg/ml respectively. In 20 of the 22 patients, surgery was successful in curing PHPT (91%). One patient had persistent hypercalcemia due to a missed adenoma, and repeat operation (by focused minimal access surgery) was successfully performed 2 weeks later. There were no complications and no morbidity postoperatively. Mean postoperative serum calcium, phosphorous and PTH were 9.6 ± 1.2 mg/dl, 3.0 ± 0.5 mg/dl and 35.2 ± 24 pg/ml respectively. In all patients, serum calcium levels remained normal (9.7 ± 1.3 mg/ml) after long-term follow-up (mean 17.7 ± 9.6 months).

Conclusions: Minimally invasive, radio-guided focused parathyroidectomy for a single adenoma is a safe and effective method to cure hyperparathyroidism in the elderly. Success of surgery is directly related to the surgeon's experience and to the precise localization marking provided by sestamibi scintigraphic SPECT localization and concurrent sonographic findings.

Background: During a period of 13 months - 1 October 2000 to 31 October 2001 – 586 terror assault casualties were treated in the trauma unit and emergency department of Hadassah University Hospital (Ein Kerem campus); 27% (n = 158) were hospitalized and the rest were discharged within 24 hours.

Objectives: To analyze the special requirements of a large number of victims who received treatment during a short period.

Methods: Data were attained from the main admitting office and the trauma registry records. Analysis was conducted of: age, gender, mechanism of injury, anatomic site of injury, Injury Severity Score (ISS), and length of stay.

Results: Males comprised 81% of the hospitalized patients. The majority of the injuries (70%) were due to gunshot wounds and 31% of the hospitalized patients were severely injured (ISS ≥ 16). Twelve patients died, yielding a mortality rate of 7.5%.

Conclusion: The nature of the injuries was more complex and severe than trauma of other etiologies, as noted by the mean length of stay (10.2 vs. 7.2 days), mean intensive care unit stay (2.8 vs. 0.9 days), and mean operations per patient (0.7 vs. 0.5). The mean insurance cost for each hospitalized terror casualty was also higher than for other trauma etiologies (US$ 3,200 vs. 2,500).

Background: Each winter influenza activity is a major cause of morbidity and mortality both in Israel and worldwide.

Objectives: To identify the influenza viruses active in Israel during the winter season and to assess the extent of influenza morbidity.

Methods: Information was collected on a population of 18,684 individuals enrolled in two community clinics in central Israel. It included the total number of visits for acute respiratory infection – including influenza and influenza-like illness (ARI/flu-like) – during a 20 week surveillance period (23 November 1997 to 27 March 1998) and the percent of influenza virus isolates in nasopharyngeal specimens from a sample of patients with ARI/flu-like collected on a weekly basis during the same period.

Results: A total of 5,947 visits for ARI/flu-like were recorded among 18,684 enrolled patients in two community clinics (18.1%). The progressive increase in the number of visits for ARI/flu-like reached a peak on week 2/98 with 597 visits and a rate of 31.95 visits per 1,000 population. After this, a decrease to the initial values was evident by week 12/98. Most affected patients were in the age groups 5–14 and 65 years and over, with a rate of 733.5 and 605.3 visits per 1,000 population, respectively. Influenza virus was isolated from 92 of the 426 nasopharyngeal specimens (21.6%). The most commonly detected strain was A/Sydney/5/97(H₃N₂) like (77.2%). The peak rate of isolates was recorded at the beginning of January (01/98).

Conclusions: A/Sydney/5/97(H₃N₂) like-strain was the dominant influenza virus. Its presence did not prevent the simultaneous activity of influenza A/H₁N₁ virus. The dynamic of the clinical disease as expressed by the weekly visit rate for ARI/flu-like was similar to the temporal pattern of the virological findings. The extent of morbidity suggests moderate epidemic activity.
 

Background: Fibroadema, one of the most common benign breast lesions, has a characteristic age-specific incidence and is associated with other pathological entities in 50% of cases. The clinical or imaging diagnosis of fibroadenoma may be erroneous, and in some cases is found to be invasive cancer. The clustering of such entities, their correlation with age, and the risk of synchronous breast malignancy are uncertain.

Objective: To explore the possibility of any sigficant clustering of fibroadenoma-associated benign breast disease and to assess the possible risk of concomitant breast cancer.

Method: We analyzed the pathological results of 147 women undergoing excisional biopsies for fibroadenoma diagnosed pre-operatively either by clinical examination and imaging (n=117) or by radiology alone (n=30). The inter-relationships among all entities associated with fibroadenoma were studies by hierarchial cluster analysis. The correlation of the various pathologies with the risk of invasive breast cancer in relation to the patient’s age was also evaluated.

Results: Fibroadema-associated pathologies were found in 48% of the cases: sclerosing adenosis (23%), duct ectasia (17/7%), apocrine metaplasia (15.6%), florid fibrocystic disease (12.9%), duct papillomatosis (11.6%), infiltrating duct carcinoma (5.4%), duct carcinoma in situ (3.4%), and 1 case of lobular carcinoma in situ (0.6%). An orderly internal hierarchy and three significant clusters emerged: a) epithelial apocrine metaplasia, duct ectasia and sclerosing adenosis (similarity coefficients 16.0, 11.0 and 8.0 respectively); b) papillomatosis, florid fibrocystic disease and calcifications (similarity coefficients of 6.0, 4.0 and 2.0 respectively); and c) infiltrating duct carcinoma in situ (similarity coefficients of 1.8 and 1.6 respectively). Seven of the eight patients with breast cancer were older than 40 years.

Conclusions: In about half of the cases fibroadema was associated with other pathological entities clustered in an orderly hierarchy. The rarity of synchronous breast cancer in the younger age group and its more common association with fibroadema in the older age groups dictate a different approach to each. The finding of fibroadema in women older than 40 indicates the need for surgical excision.
