Objectives: To retrospectively determine the clinical response to ¹³¹I-MIBG therapy at low doses in patients with refractory neuroblastoma.

Methods: We performed a retrospective chart review of 10 patients with neuroblastoma treated with ¹³¹I-MIBG at Rambam Health Care Campus from 1994 to 2012. Clinical data, number of ¹³¹I-MIBG courses delivered, toxicities, and clinical responses were reviewed. MIBG scan was performed after each course.

Results: Twenty-one courses of ¹³¹I-MIBG were delivered to 10 patients (3 girls, 7 boys). Their mean age was 3.8 years (range 1.5–6 years). All patients received several protocols of chemotherapy including the high dose form. Three patients received three courses of ¹³¹I-MIBG with a minimum of 6 weeks between each course, five patients received two courses, and two patients received only one course. An objective response to the first course was obtained in nine patients and to the second course in six of eight, and in three children who underwent the third course the pain decreased. One patient has no evidence of disease, four are alive with disease, and five died of the disease. No unanticipated toxicities were observed.

Conclusions: Low dose ¹³¹I-MIBG is an effective and relatively non-toxic treatment in neuroblastoma disease palliation. Rapid and reproducible pain relief with ¹³¹I-MIBG was obtained in most of the children. Treatment with systemic radiotherapy in the form of low dose ¹³¹I-MIBG was easy to perform and effective in cases of disseminated neuroblastoma, demonstrating that this primary therapy can be used for palliative purposes.

Background: The management of sexual assault victims comprises complex medical, psychological, social and judicial care that was previously provided by various disciplines at several distant locations. This novel concept is the delivery of comprehensive care to victims of sexual assault at one location 24 hours a day.

Objectives: To describe the characteristics of sexual assault victims, their assailants, the assault and the treatment, and provide descriptive data on the evidentiary examination.

Methods: We performed a retrospective analysis of the charts of all sexual assault victims presenting to the Regional Israeli Center for Care of Sexual Assault Victims between October 2000 and July 2010. The center, the first in Israel, provides comprehensive care to victims of sexual assault in one location 24 hours a day using a multidisciplinary approach.

Results: The study group comprised 1992 subjects; 91.5% of the victims were females and 8.5% were males, and the age ranged from 1 to 88 years (mean age 22.3 years). Of the 1992 victims, 1635 were single (82.2%), 195 were divorced (9.8%), 141 were married (7.1%), 18 were widowed (0.9%) and 3 were unspecified. The assailant was a stranger in 794 (39.8%) of the cases, someone familiar to the victim in 786 cases (39.0%), a partner in 127 cases (6.4%), a family member in 117 cases (5.9%), someone met via the internet in 53 cases (2.7%), an authority figure in 39 cases (2.0%), and unspecified in 76 (3.9%). In the majority of cases the attack occurred either in the evening or at night (71.7%).

Conclusions: We identified several risk factors for sexual assault that can be used in prevention programs. The sexual assault victim in our study tended to be a young, single woman who was attacked by a familiar assailant in the evening or at night. Our center provides comprehensive care to victims 24 hours a day at one location and includes a team of forensic, psychological, physical and legal specialists.
 

 Background: Vitamin D status is not evaluated routinely in cancer patients with bone metastasis who are treated with bisphosphonates.

Objectives: To assess the effect of vitamin D status on risk of hypocalcemia and quality of life in these patients.

Methods: We performed laboratory tests for routine serum biochemistry, 25(OH)D, plasma parathyroid hormone (PTH) and bone turnover markers (CTX, P1NP) in 54 patients aged 57.5 ± 13 years treated with intravenous bisphosphonates.

Results: Most of the patients (n=44, 77.8%) did not receive calcium and vitamin D supplementation. Their mean serum 25(OH)D levels (12.83 ± 6.86 ng/ml) correlated with vitamin D daily intake (P = 0.002). In 53 patients (98.1%) 25(OH)D levels were suboptimal (< 30 ng/ml). Albumin-corrected calcium levels correlated with plasma PTH (P = 0.001). No correlation was observed between daily calcium intake and serum calcium (P = 0.45). Hypocalcemia was observed in one patient. Mean plasma PTH was 88.5 ± 65 ng/L. Plasma PTH correlated negatively with 25(OH)D serum levels (P = 0.003) and positively with P1NP (P = 0.004). Albumin-corrected calcium correlated negatively with P1NP (mean 126.9 ± 191 ng/ml) but not with CTX levels (mean 0.265 ± 0.1 ng/ml) (P < 0.001). There was no correlation among quality of life parameters, yearly sun exposure and 25(OH)D levels (P = 0.99).

Conclusions: Vitamin D deficiency is frequent in oncology patients with bone metastasis treated with bisphosphonates and might increase bone damage. Our results indicate a minor risk for the development of severe hypocalcemia in vitamin D-deficient patients receiving bisphosphonate therapy. Although vitamin D deficiency might have some effect on the quality of life in these patients, it was not proven significant.
 

Background: The presence of stones in the common bile duct (CBD) may cause complications such as obstructing jaundice or ascending cholangitis, and the stones should be removed.

0bjectives: To report our results with percutaneous elimination of CBD stones from the gallbladder through the papilla.

Methods: During a 4 year period, six patients (five men and one woman, mean age 71.5 years) who had CBD stones and an existing gallbladder drain underwent percutaneous stone push into the duodenum after balloon dilatation of the papilla, with a diameter equal to that of the largest stone. Access into the CBD was from the gallbladder, using an already existing percutaneous gallbladder drain (cholecystostomy tube).

Results: Each patient had one to three CBD stones measuring 7–14 mm. Successful CBD stone elimination into the duodenum was achieved in five of the six patients. The single failure occurred in a patient with choledochal diverticulum, who was operated successfully. There were no major or minor complications during or after the procedures.

Conclusions: Trans-cholecystic CBD stone elimination is a safe and feasible percutaneous technique that utilizes existing tracts, thus obviating the need to create new percutaneous access. This procedure can replace endoscopic or surgical CBD exploration.
 

Background: Delayed diagnosis of choroidal neovascularization (CNV) in age-related macular degeneration (AMD) adversely affects visual outcome.

Objectives: To identify factors associated with early detection of CNV in the clinic setting.

Methods: Demographic and clinical data and lesion characteristics were retrospectively collected from 76 consecutive AMD patients who had a history of CNV in one eye and presented with CNV in the second eye. These data were evaluated for association with visual acuity (VA) at the time of presentation.

Results: Better VA was associated with a history of CNV in the fellow eye (P < 0.0001), adherence to follow-up every 4 months (P = 0.015), younger age (P = 0.03), smaller lesion (P < 0.0001), and non-subfoveal location (P = 0.048). VA of the fellow eye did not correlate with VA at presentation with CNV.

Conclusions: These data suggest that patients’ experience of CNV, regardless of VA, facilitates early diagnosis in the fellow eye. Adherence to follow-up in the routine clinic setting also facilitates early detection of CNV.

Background: On 4 February 2008, two terrorists armed with suicide bombs arrived at the open market in the southern Israeli city of Dimona. One detonated his bomb at approximately 10:30 a.m. causing multiple casualties. Short-term emotional effects and acute stress reactions usually appear among survivors after such incidents.

Objectives: To compare the differences in emotions and in disturbances of daily life activities that emerge a couple of days following such an event and to identify patterns of stress development among resilient and low-resilient members of the population in Dimona and in the general population of Israel.

Methods: A telephone survey of two randomly selected representative samples of adults (428 Israeli residents and 250 Dimona residents) was conducted 2 days after the event.

Results: A higher prevalence of stress and fear and a lower prevalence of joy were reported among the population of Dimona compared to the general population in Israel (P < 0.05). Differences were also recorded when the population of Dimona was categorized by their personal degree of resilience (P < 0.05). A higher prevalence of disturbances in daily life activities and changes in leisure activity was found in the low-resilient population in Dimona (P < 0.01).

Conclusions: This study demonstrates that following a public terror event, self-reported low-resilient subjects have a higher prevalence of disturbances in daily life activities, as well as adverse emotional responses. These differences must be addressed by the relevant social service agencies for immediate public intervention

Background: Human milk produced during prolonged lactation (> 1 year) is extraordinarily rich in fat and has a higher energy content than human milk produced during short lactation.

Objectives: To estimate the fatty acid (FA) profile of human milk and to test the hypothesis that the proportion of C12 and C14 (two dietary saturated FA known to most promote hypercholesterolemia) in human milk during prolonged lactation is similar to that in short lactation.

Methods: We conducted a cross-sectional study of 30 mothers of term infants lactating for more than 1 year as compared with 25 mothers of full-term infants who lactated for 2–6 months. Milk was collected by manual expression in mid-breastfeeding.

Results: The two groups did not differ in maternal height, weight, body mass index, diet, infant birth weight and gestational age, but mothers in the prolonged lactation group were significantly older. There was a significant correlation between lactation duration and C12 or C14. The percentage of all FA combined (except for C12 and C14) decreased significantly over time. In contrast, C12:0 and C14:0 combined increased significantly during lactation (R2 = 10.0%, P < 0.03).

Conclusions: Women who lactated for more than 1 year had higher C12 and C14 FA percentages in their milk than women who lactated for 2–6 months.
