Background: Comorbid depression may play an important role in non-compliance with medical treatment among patients with chronic illnesses. Glaucoma is a potentially blinding chronic disease requiring life-long commitment to medical therapy. Patient's failure to adhere to anti-glaucoma treatment may lead to disease progression and visual loss.

Objectives: To assess the prevalence of depressive symptoms in glaucoma patients and the association between these symptoms and non-compliance with anti-glaucoma therapy.

Methods: This was a cross-sectional observational study. Compliance with pharmacotherapy was assessed with the Morisky Medication Adherence questionnaire (eight items). Screening for depression was performed by means of the CES-D scale (Center for Epidemiologic Studies Depression scale). The association between depression and compliance rates was analyzed.

Results: The study group comprised 76 glaucoma patients; 19.7% of the subjects were classified as "non-compliant" (Morisky cutoff < 10) and 21.1% suffered from depression (CES-D cutoff ≥ 16). We found a similar level of non-compliance when comparing depressed with non-depressed glaucoma patients. However, a significant correlation was observed between the level of depression and the level of non-compliance (P = 0.04).

Conclusions: Our study revealed a similar rate of depression in glaucoma patients and the general Israeli population. The presence of depression was not associated with the presence of non-compliance, yet the level of depression was associated with the level of non-compliance.

Background: Surgery is considered the mainstay of treatment for esophageal carcinoma. Transhiatal esophagectomy with cervical esophagogastric anastomosis is considered relatively safe with an oncological outcome comparable to that using the transthoracic approach.

Objectives: To review the results of the first 100 transhiatal esophagectomies performed in a single Israeli center.

Methods: The records of all patients who had undergone transhiatal esophagectomy during the period 2003–2009 were reviewed. The study group comprised the first 100 patients. All patients who had undergone colon or small bowel transposition were excluded. Indications for surgery included esophageal cancer, caustic injury and achalasia.

Results: The median follow-up period was 19.5 months. The anastomotic leakage rate was 15% and all were managed successfully with local wound care. The benign stricture rate was 10% and all were managed successfully with endoscopic balloon dilation. Anastomotic leakage was found to be a risk factor for stricture formation. Overall survival was 54%. Response to neoadjuvant therapy was associated with a favorable prognosis.

Conclusions: Transhiatal esophagectomy is a relatively safe approach with adequate oncological results, as long as it is performed in a high volume center.
 

Background: The effect of anti-platelet drugs on surgical blood loss and perioperative complications has not been studied in depth and the management of surgical patients taking anti-platelet medications is controversial.

Objective: To assess the effect of anti-platelet therapy on perioperative blood loss in patients undergoing appendectomy either laparoscopically or via open surgery.

Methods: We reviewed the files of all patients > 40 years old who underwent open or laparoscopic appendectomies from 2007 to 2010. Excluded were patients with short hospitalization and no follow-up of hemoglobin level, patients on warfarin treatment and patients who underwent additional procedures. Estimation of blood loss was based on decrease in hemoglobin level from admission to discharge. Risk factors for blood loss, such as anti-platelet therapy, age, gender, surgical approach, surgical time, surgical findings and complications, were analyzed.

Results: The final cohort included 179 patients (mean age 61 ± 14 years, range 40–93) of whom 65 were males. The mean perioperative hemoglobin decrease was 1.59 ± 1.07 mg/dl (range 0–5 mg/dl). Thirty-nine patients received anti-platelet therapy prior to surgery and 140 did not. No significant differences in decrease of hemoglobin level were found between patients receiving anti-platelet therapy and those who were not (1.73 ± 1.21 vs. 1.55 ± 1.02 mg/dl, P = 0.3). In addition, no difference was found between patients on anti-platelet therapy operated laparoscopically and those operated in an open fashion (1.59 ± 1.18 vs. 2.04 ± 1.28 mg/dl, P = 0.29). Five patients required blood transfusions, two of whom were on anti-platelet therapy. Blood loss was significantly greater in patients with a perforated appendicitis and in those with an operative time of more than one hour.

Conclusions: Anti-platelet therapy does not pose a risk for increased blood loss following emergent appendectomy performed either laparoscopically or in an open fashion.
 

Background: Music therapy has been recommended as an adjuvant therapy for both preterm infants and mothers during their stay in the neonatal intensive care unit (NICU), and has been shown to have beneficial effects.

Objectives: To study the usefulness of combining live harp music therapy and kangaroo care (KC) on short-term physiological and behavioral parameters of preterm infants and their mothers in the NICU setting.

Methods: Included in this study were stable infants born between 32 and 37 weeks of gestation, with normal hearing .Mother-infant dyads were randomly assigned to KC and live harp music therapy or to KC alone. Using repeated measures, neonatal and maternal heart rate, oxygen saturation and respiratory rate were recorded along with neonatal behavioral state and maternal anxiety state. Maternal age, ethnicity, education, and love of music were documented.

Results: Fifty-two mother-infant dyads were tested. Compared with KC alone, KC and live harp music therapy had a significantly beneficial effect on maternal anxiety score (46.8 ± 10 vs. 27.7 ± 7.1, respectively, P < 0.01). Infants’ physiological responses and behavior did not differ significantly. No correlation was found between mothers’ age, ethnicity, years of education and affinity for music, and anxiety scores (P = 0.2 to 0.5 for all four variables).

Conclusions: KC combined with live harp music therapy is more beneficial in reducing maternal anxiety than KC alone. This combined therapy had no apparent effect on the tested infants’ physiological responses or behavioral state.
 

Background: Infiltrating ductal carcinoma and infiltrating lobular carcinoma account for more than 90% of all invasive breast cancer histological types. The rate of ILC[1] is reported to be increasing steadily in the United States and Europe.

Objectives: To describe the trend in the incidence of ILC in a large cohort of patients who underwent surgery in a single institution over an 18 year period.

Methods: Our comprehensive database of 2175 consecutive patients with invasive breast cancer diagnosed during the period 1992–2009 served for the analysis. Several potential factors associated with lobular carcinoma as compared with ductal carcinoma were evaluated.

Results: During this period, a 2.4-fold increase in the incidence of pure ILC was noted, from 4.6% in the years 1992–1994 to 10.9% in 2004–2006, followed by a modest decrease to 8.7% in 2007–2009. A significant association of lobular malignancies with external hormonal use was noted, including hormone replacement therapy exposure in patients diagnosed at age 50–64, and ovarian overstimulation during in vitro fertilization in those diagnosed at age 50 or less.  

Conclusions: Better diagnostic tools – such as the liberal use of ultrasound and magnetic resonance imaging – and more accurate pathological definition for ILC type appear to influence the changes in the incidence of ILC in the subgroups of invasive breast cancer.

Background: Tuberculosis is the most common opportunistic infection among people infected with human immunodeficiency virus and its first cause of morbidity and mortality.

Objectives: To analyze the characteristics of a population in Israel with both tuberculosis disease and HIV[1] infection in order to identify factors that contribute to outcome.

Methods: The study group comprised patients hospitalized in the Pulmonary and Tuberculosis Department of Shmuel Harofeh Hospital during the period January 2000 to December 2006. They were located by a computer search in the hospital registry and the pertinent data were collected.

Results: During the study period 1059 cases of active tuberculosis disease were hospitalized; 93 of them were co-infected with HIV. Most of them came from endemic countries (61.2% from Ethiopia and 20.4% from the former Soviet Union; none of them was born in Israel). Ten percent of the cases were multiple-drug resistant and 32% showed extrapulmonary involvement. The response rate to the treatment was good, and the median hospitalization time was 70 days. The mortality rate was 3.2%.

Conclusions: Despite the high prevalence of pulmonary disease in our group, the short-term outcome was good and the Mycobacterium was highly sensitive to first-line drugs. These encouraging results can be attributed to the fact that tuberculosis patients in Israel are identified early and treated continuously and strictly, with early initiation of antiretroviral therapy, which ensures that the development of drug resistance is low.

Background: High sensitivity C-reactive protein, a marker of inflammation, has been proposed to stratify coronary artery disease risk and is lowered by HMG-CoA reductase (statin) therapy. However, the reproducibility of persistently elevated hs-CRP[1] levels and association with other markers of inflammation in patients with stable CAD[2] on aggressive statin therapy is unknown.

Objectives: To determine the reproducibility of hs-CRP levels measured within 2 weeks in patients with documented CAD with stable symptoms and to identify associations with other markers of inflammation.

Methods: Levels of hs-CRP were measured twice within 14 days (7 ± 4) in 23 patients (22 males and 1 female, average age 66 ± 10 years) with stable CAD and hs-CRP ≥ 2.0 mg/L but ≤ 10 mg/L at visit 1. All patients had received statins for cholesterol management (low density lipoprotein-cholesterol 84 ± 25 mg/dl) with no dose change for > 3 months. None had a history or evidence of malignancy, chronic infection or inflammation, or recent trauma. There was no change in medications between visits 1 and 2, and no patient reported a change in symptoms or general health during this interval. White blood cell count and pro- and anti-inflammatory cytokines were measured at both visits.

Results: hs-CRP levels tended to be lower at visit 2 (median 2.4 mg/L, range 0.8–11 mg/L) than at visit 1 (median 3.3 mg/L, range 2.0–9.7 mg/L; P = 0.1793). However, between the two visits hs-CRP levels decreased by more than 1.0 mg/L in 10 patients and increased by more than 1.0 mg/L in 4 patients. Changes in hs-CRP levels were unrelated to changes in levels of white blood cells (P = 0.4353). Of the cytokines tested, only the anti-inflammatory cytokine interleukin-1 receptor antagonist and the pro-inflammatory cytokine interleukin-8 were above lower limits of detection, but there were no correlations between changes in these values and changes in hs-CRP (both P > 0.5).

Conclusions: In stable CAD patients on aggressive statin therapy, hs-CRP levels may fluctuate over brief periods in the absence of changes in health, cardiac symptom status and medications, and without corroboration with other measures of inflammation. Accordingly, elevated hs-CRP levels should be interpreted with caution in this setting.
