Background: Holocaust survivors report a much higher prevalence of osteoporosis and fracture in the hip joint compared to those who were not Holocaust survivors.

Objective: To evaluate whether being a Holocaust survivor could affect the functional outcome of hip fracture in patients 64 years of age and older undergoing rehabilitation.

Methods: A retrospective cohort study compromising 140 consecutive hip fracture patients was conducted in a geriatric and rehabilitation department of a university-affiliated hospital. Being a Holocaust survivor was based on registry data. Functional outcome was assessed by the Functional Independence Measure (FIM)TM at admission and discharge from the rehabilitation ward. Data were analyzed by t-test, chi-square test, and linear regression analysis. 

Results: Total and motor FIM scores at admission (P = 0.004 and P = 0.006, respectively) and total and motor FIM gain scores at discharge (P = 0.008 and P = 0.004 respectively) were significantly higher in non-Holocaust survivors compared with Holocaust survivors. A linear regression analysis showed that being a Holocaust survivor was predictive of lower total FIM scores at discharge (β = -0.17, P = 0.004).

Conclusion: Hip fracture in Holocaust survivors showed lower total, motor FIM and gain scores at discharge compared to non-Holocaust survivor patients. These results suggest that being a Holocaust survivor could adversely affect the rehabilitation outcome following fracture of the hip and internal fixation. 

 

Background: Four-dimensional parathyroid computed tomography (4DCT) is a relatively new parathyroid imaging technique that provides functional and highly detailed anatomic information about parathyroid tumors.

Objective: To assess the accuracy of 4DCT for the preoperative localization of parathyroid adenomas (PTAs) in patients with biochemically confirmed primary hyperparathyroidism (PHPT) and a history of failed surgery or unsuccessful localization using ^99mTc-sestamibi scanning and ultrasonography.

Methods: Between January 2013 and January 2015, 55 patients with PHPT underwent 4DCT at Hillel Yaffe Medical Center, Hadera, Israel. An initial unenhanced scan was followed by an IV contrast injection of nonionic contrast material (120 ml of at 4 ml/s). Scanning was repeated 25, 60, and 90 seconds after the initiation of IV contrast administration. An experienced radiologist blinded to the earlier imaging results reviewed the 4DCT for the presence and location (quadrant) of the suspected PTAs. At the time of the study, 28 patients had undergone surgical exploration following 4DCT and we compared their scans with the surgical findings.

Results: 4DCT accurately localized 96% (27/28) of abnormal glands, all of which were hypervascular and showed characteristic rapid enhancement on 4DCT that could be distinguished from Level II lymph nodes. Surgery found hypovascular cystic PTA in one patient who produced a negative 4DCT scan. All patients had solitary PTAs. The scan at 90 seconds provided no additional information and was abandoned during the study.

Conclusions: 4DCT accurately localized hypervascular parathyroid lesions and distinguished them from other tissues. A three-phase scanning protocol may suffice.

Background: The number of cancer survivors has been increasing worldwide and is now approximately 32.6 million and growing. Cancer survivors present a challenge to health care providers because of their higher susceptibility to long-term health outcomes related to their primary disease and treatment.

Objective: To report on the number of cancer survivors and incident cancer cases in the period 1960–2009 in Israel, in order to provide data on the scope of the challenge Israel’s health care funds face.

Methods: The Israel National Cancer Registry (INCR) database was used to identify new cancer cases diagnosed during the period 1960–2009. Lifetable analysis was used to assess changes in cumulative survival and population prevalence of cancer survivors throughout the 50 year study period.

Results: Almost 600,000 invasive cancer cases were diagnosed during the period 1960–2009 (overall absolute survival rate 54%). Within this time period, the number of new patients diagnosed with cancer increased fivefold and that of cancer survivors ninefold. The absolute survival of cancer patients and the prevalence of cancer survivors in the general population significantly increased with time from 34% and 0.5%, respectively (1960–1969), to 62% and 1.9%, respectively (2000–2009). Cumulative absolute survival for 5, 10 and 15 years following diagnosis increased with time as well.

Conclusions: The INCR database is useful to assess progress in the war against cancer. The growing numbers of cancer survivors in Israel present a challenge to the national health and social services system.

Background: The treatment of patients hospitalized with heart failure (HHF) and ambulatory chronic heart failure (CHF) differs in various countries.

Objective: To evaluate the management and outcomes of patients with HFF and CHF in Israel compared to those in other European countries who were included in the ESC-HF Long-Term Registry.

Methods: From May 2011 to April 2013, heart failure patients – 467 Israelis and 11,973 from other countries – were evaluated. The Israeli patients included 178 with HHF and 289 with CHF. One year outcomes, including all-cause and cardiovascular mortality as well as HHF, were evaluated.

Results: The HHF Israeli patients were older than their CHF Israeli counterparts, had more co-morbidities, included more women, and were treated less frequently with medications suggested by European guidelines. The Israeli HHF patients had similar all-cause 1 year mortality rates compared to HHF patients from other participating countries, but their cardiovascular (CV) mortality was lower, while a significantly higher rate of all-cause and HHF was noted. The Israeli CHF patients were older, suffered from more co-morbidities and had prior cardio-electronic implantable devices. In addition, they had higher mortality rates, especially non-CV, and were more frequently hospitalized, compared to CHF patients from other countries.

Conclusions: The Israeli patients with heart failure differed in their baseline characteristics and the therapeutic approach. Despite high usage of treatments recommended by official guidelines, especially among CHF patients, mortality, particularly in HHF patients, remained high.

Background: Diagnosis of abdominal lymphadenopathy is challenging when not accompanied by peripheral lymphadenopathy. Computed tomography-guided core-needle biopsy has largely replaced open procedures in recent years, but this approach is limited by access to the anatomic region and the amount of tissue acquired.

Objective: To demonstrate the feasibility of the laparoscopic approach in obtaining abdominal lymph node biopsies and to evaluate the diagnostic adequacy of the technique.

Methods: We reviewed the data of patients who underwent laparoscopic lymph node biopsy between 2014 and 2014 in our department. Demographics, intra-operative parameters and postoperative course were examined, as were histological reports. Postoperative complications were categorized according to the Clavien-Dindo(CD) classification.

Results: Between 2004 and 2014, 57 laparoscopic biopsies were performed for intra-abdominal lymphadenopathy. One case was a repeated attempt due to limited histologic material. The mean age was 49.5 ± 19.6 years. There were two conversions to open laparotomy, one due to small bowel injury and the other due to a sizable mass. Overall, 56 cases had full clinical data: 48 cases (85.7%) had CD=0, six (10.7%) had CD=1, one postoperative severe complication (CD=3) and one mortality (CD=5), which was related to preexisting hepatic insufficiency. Mean hospital stay was 1.6 days. Overall, adequate tissue samples were acquired in 96.7% and only 3 of these cases resulted in inconclusive diagnoses.

Conclusions: Laparoscopic lymph node biopsy is a viable alternative to the currently available methods of tissue retrieval. It provides an access for nodes which are inaccessible percutaneously, and may allow a superior diagnostic yield.

Background: Recurrent tuberculosis (TB) is one of the indices used to assess the effectiveness of the Israeli National TB Programs (NTP).

Objectives: To estimate the incidence of recurrent TB in Israel and to identify the associated risk factors.

Methods: We conducted a retrospective cohort study of all TB patients who were Israeli citizens and diagnosed between 1999 and 2011 with a treatment outcome recorded as “success." We compared those who had recurrent TB with those who did not. In addition, a nested case-control study included all those who had recurrent TB with a random sample from this cohort matched by age, gender, and year of TB diagnosis.

Results: Of 3515 TB patients diagnosed between 1999 and 2011, 37 (1.05%) had recurrent TB during the follow-up period, with an incidence rate of 1.55 cases per 1000 person-years (PY). Male gender [hazard ratio (HR) 3.2, 95% confidence interval (95%CI) 1.4–7.4], human immunodeficiency virus (HIV) infection (HR 3.9, 95%CI 1.5–10.4), positive sputum culture [odds ratios (OR) 2.7, 95%CI 1.1–6.9], and low adherence to anti-TB treatment (OR 3.2, 95%CI 1.0–10.3) were found to be risk factors for recurrent TB.

Conclusions: Male gender, HIV infection, positive sputum culture, and low adherence to anti-TB drugs during the initial TB episode were risk factors for developing recurrent TB.

Background: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease which refers to the presence of hepatic steatosis. Breast cancer is now the most common cancer in women and is the leading cause of death from cancer among women.

Objectives: To assess the relationship between NAFLD and newly diagnosed cases of breast cancer.

Methods: The results of mammography screening examinations in women referred to the Breast Center, Holy Family Hospital, Nazareth during a 4 year period were collected. We identified cases of women who were newly diagnosed with breast cancer and who underwent abdominal computed tomography (CT) within 1 month of the diagnosis. The control group comprised 73 women with normal mammography and breast ultrasonography who underwent abdominal CT within 3 months from the date of the breast cancer screening during the same study period. The control cases were matched by age and body mass index (BMI). We compared the cases with the controls in terms of the presence of diffuse hepatic fatty liver and other known risk factors for breast cancer.

Results: Of the 133 women who were screened, 73 with new diagnosis of breast cancer were eligible for the study. NAFLD was found in 33 of the women with breast cancer and in 12 in the control group (45.2% vs.16.4%, respectively, P = 0.002). Multivariate analysis showed NAFLD (odds ratio 2.82, 95% confidence interval 1.2–5.5, P = 0.016) to be associated with breast cancer.

Conclusions: NAFLD is associated with breast cancer.

Background: The very long-term prognostic significance of ventricular late potentials (VLP) in patients post ST-elevation myocardial infarction (STEMI) is unclear.

Objective: To evaluate the long-term predictive value of VLP for mortality post-STEMI.

Methods: We conducted serial signal-averaged electrocardiography (SAECG) measurements in 63 patients on the 1st, 2nd and 3rd day pre-discharge, and 30 days after STEMI in patients admitted in 2001. We followed the patients for 10 years and correlated the presence of VLP with all-cause and cardiovascular mortality.

Results: The mean age was 59.9 ± 12.3 years. Thrombolysis was performed in 41 patients (65%). Percutaneous coronary intervention was performed pre-discharge in 40 patients (63%) and coronary artery bypass grafting in 7 (11%). Five consecutive measurements to define the presence of VLP were obtained in 52 patients (21 with VLP and 31 without). We found a higher prevalence of VLP in males compared to females (QRS segment > 114 msec, 51% vs. 12%, P = 0.02, duration of the low amplitude signal < 40 mV) in the terminal portion of the averaged QRS complex > 38 msec, 47% vs. 25%, P = 0.05). Over 10 years of follow-up, 14 (22%) patients died, 10 (70%) due to cardiovascular non-arrhythmic complications, 6 with VLP compared to only 3 without (28.6% vs. 9.7%, P = 0.125, hazard ratio = 2.96, confidence intervals = 0.74–11.84) (are these numbers meant to total 10?).

Conclusions: Over 10 years of follow-up, the presence of VLP in early post-STEMI is not predictive of arrhythmic or non-arrhythmic cardiovascular mortality.

Background: The optimal approach to the evaluation of asymptomatic bacteruria in stroke patients is uncertain. 

Objectives: To compare elderly patients after an acute stroke with and without asymptomatic bacteriuria for the development of symptomatic urinary tract infections (UTI).

Methods: We prospectively monitored patients over 65 years of age admitted to our rehabilitation hospital after an acute stroke, with and without asymptomatic bacteriuria, for the development of symptomatic UTIs. The prevalence of bacteriuria was determined by urine cultures obtained 2 and 4 weeks after admission. Patients with and without persistent bacteriuria were compared to identify variables associated with bacteriuria.

Results: Fifty-five patients were included in the study. The prevalence of asymptomatic bacteriuria at baseline was 20%. Of all 55 stroke patients, 13 (23.6%) developed a symptomatic UTI during the 30 day follow-up. Patients with stroke and asymptomatic bacteriuria at baseline had an increased risk of developing a symptomatic UTI (54.5% with asymptomatic bacteriuria vs. 15.9% without, P = 0.011). To exclude the effects of several confounders, we performed multivariate Cox regression analysis, which showed that bacteruria remained a significant covariate for symptomatic UTI (hazard ratio 2.86, 95% confidence interval 0.71–10.46, P = 0.051). When subjects who experienced symptomatic urinary infection were included, the prevalence of bacteriuria in the study cohort declined to about 45.5% by 30 days. 

Conclusion: Elderly patients with stroke and asymptomatic bacteriuria have an increased risk of developing a symptomatic UTI compared to those without asymptomatic bacteriuria during a 30 day post-stroke follow-up.

 

Background: Warm compresses are widely touted as an effective treatment for ocular surface disorders. Black tea compresses are a common household remedy, although there is no evidence in the medical literature proving their effect and their use may lead to harmful side effects. 

Objectives: To describe a case in which the application of black tea to an eye with a corneal epithelial defect led to anterior stromal discoloration; evaluate the prevalence of hot tea compress use; and analyze, in vitro, the discoloring effect of tea compresses on a model of a porcine eye.

Methods: We assessed the prevalence of hot tea compresses in our community and explored the effect of warm tea compresses on the cornea when the corneal epithelium’s integrity is disrupted. An in vitro experiment in which warm compresses were applied to 18 fresh porcine eyes was performed. In half the eyes a corneal epithelial defect was created and in the other half the epithelium was intact. Both groups were divided into subgroups of three eyes each and treated experimentally with warm black tea compresses, pure water, or chamomile tea compresses. We also performed a study in patients with a history of tea compress use. 

Results: Brown discoloration of the anterior stroma appeared only in the porcine corneas that had an epithelial defect and were treated with black tea compresses. No other eyes from any group showed discoloration. Of the patients included in our survey, approximately 50% had applied some sort of tea ingredient as a solid compressor or as the hot liquid.

Conclusions: An intact corneal epithelium serves as an effective barrier against tea-stain discoloration. Only when this layer is disrupted does the damage occur. Therefore, direct application of black tea (Camellia sinensis) to a cornea with an epithelial defect should be avoided.
