Background: Atypical presentation of tuberculosis (TB) during pregnancy may cause diagnostic delay and adversely influence pregnancy outcome. 

Objectives: To examine the incidence and clinical and epidemiological features of TB during pregnancy and investigate infection control measures at delivery and during the postpartum period.

Methods: We retrospectively evaluated all reported cases of TB diagnosed during pregnancy to 6 months postpartum in Israel’s Northern Health District (2002–2012). 

Results: Active TB was detected in six patients; all were negative for human immunodeficiency virus (HIV). Two patients were diagnosed in the postpartum period, and four had pulmonary involvement. The average incidence during this period (3.9 per 100,000 pregnancies) was similar to that in the general population. Five patients were at high risk of contracting TB due to either recent immigration from a high-burden country or being in contact with another individual with active TB. Patients with pleuropulmonary involvement had prolonged cough and abnormal chest X-rays, without fever. Diagnosis was delayed for 3 to 7 months from symptom onset. Investigation of the newborn to rule out intrauterine infection was conducted in only one of four relevant cases. All patients were infected with organisms susceptible to all first-line drugs, and all were cured with standard therapy.

Conclusions: There was a considerable delay in the diagnosis of TB among pregnant women, and investigation of the newborn upon delivery to rule out TB infection was routinely omitted. Effective management of TB during pregnancy and the postpartum period requires a multidisciplinary approach including an obstetrician, pediatrician, TB specialist, and public health physician.

 

Background: The number of patients awaiting organ transplantation continues to exceed the number of available organs. 

Objectives: To document changes in the demographic characteristics of brain-dead, heart-beating organ donors over the past 10 years which may impact on organ utilization. 

Methods: Data were extracted from the Israel Transplant Registry and the Donor Action database for the 10 year period 2004–2013, inclusive. 

Results: The median age of the donors increased from 44 (range 3–73 years) to 53.5 years (range 1–79 years) (P < 0.001). There was a significant increase in the median age of donors of kidney (33 to 51 years, P < 0.001), liver (41 to 53 years, P < 0.001) and lung (40 to 49.5 years, P < 0.001). The number of donors dying from trauma decreased (34.5% to 20%, P < 0.001), while those with anoxic brain damage increased (14.5% to 25%, P < 0.001). The percent of male donors decreased over the study period, from 63% to 53%. An increase was noted in the mean number of organs transplanted per donor, from 3.29 to 3.82 per donor, due mainly to a significant increase in the utilization of lungs (31.5% to 51.3%, P < 0.001) and livers (76.3% to 82.4%, P < 0.001) while heart utilization decreased significantly since 2006 (40.9% to 17.5%, P < 0.001). 

Conclusion: Trends in the heart-beating, brain-dead organ donor pool in Israel over the past 10 years reveal significant changes in demographic characteristics which in the future will impact on the number of organs available for transplantation. 

 

Abstract

Background: Diabetes mellitus-related lower extremity amputation is a major complication severely affecting patient survival and quality of life.

Objectives: To analyze epidemiological and clinical trends in the incidence and survival of lower extremity amputations among diabetes patients.

Methods: We conducted a retrospective observational cohort study of 565 consecutive diabetes patients who underwent their first non-traumatic lower extremity amputation between January 2002 and December 2009.

Results: Major amputations were performed in 316 (55.9%) patients: 142 above the knee (25.1%) and 174 below (30.8%); 249 (44.1%) had a minor amputation. The incidence rates of amputations decreased from 2.9 to 2.1 per 1000 diabetes patients. Kaplan-Meier survival analysis showed that first year mortality rates were lower among patients with minor amputations (31.7% vs. 39.6%, P = 0.569). First year mortality rates following below-knee amputation were somewhat lower than above-knee amputation (33.1 vs.45.1%, respectively). Cox regression model of survival at 1 year after the procedure found that age (HR 1.06 per year, 95% CI 1.04–1.07, P < 0.001), above-knee amputation (HR 1.36, 95% CI 1.01–1.83, P = 0.045) and ischemic heart disease (HR 1.68, 95% CI 1.26–2.24, P < 0.001) significantly increased one year mortality risk.

Conclusions: In this population-based study the incidence rate of non-traumatic amputations in diabetes patients between January 2002 and December 2009 decreased slightly. However, one year mortality rates after the surgery did not decline and remained high, stressing the need for a multidisciplinary effort to prevent amputations in diabetes patients.

Abstract

Background: Scleroderma lung disease (ILD-SSc) is treated mainly with cyclophosphamide (CYC). The effectiveness of CYC was judged after 12–24 months in most reports.

Objectives: To analyze the effect of monthly intravenous CYC on pulmonary function tests including forced vital capacity (FVC) and diffusing lung capacity (DLCO), as well as Rodnan skin score (mRSS), during long-term follow-up.

Methods: We retrospectively collected the data on 26 ILD-SSc patients who began CYC treatments before 2007. Changes in FVC, DLCO and mRSS before treatment, and at 1, 4 and 7 years after completion of at least six monthly intravenous CYC treatments for ILD-SSc were analyzed.

Results: Mean cumulative CYC dose was 8.91 ± 3.25 G. More than 30% reduction in FVC (0%, 8%, and 31% of patients), DLCO (15%, 23%, 31%), and mRSS (31%, 54%, 62%) at years 1, 4 and 7 was registered. During the years 0–4 and 4–7, annual changes in FVC, DLCO and mRSS were 3.2 vs. 0.42% (P < 0.040), 4.6 vs. 0.89% (P < 0.001), and 1.8 vs. 0.2 (P = 0.002). The greatest annual FVC and DLCO reduction over the first 4 years correlated with mortality (P = 0.022). There were no differences in the main variables regarding doses of CYC (< 6 G and > 6 G).

Conclusions: In patients with ILD-SSc, CYC stabilized the reduction of FVC during treatment, but this effect was not persistent. The vascular characteristic of ILD-SSc (DLCO) was not affected by CYC treatment. CYC rapidly improved the mRSS. This effect could be achieved with at least 6 G of CYC. Higher rates of annual reduction in FVC and DLCO in the first 4 years indicate the narrow window of opportunity and raise the question regarding ongoing immunosuppression following CYC infusions.

 

Background: Low back pain (LBP) is chronic disease without a curative therapy. Alternative and complementary therapies are widely used in the management of this condition.  

Objectives: To evaluate the efficacy of home application of Dead Sea mud compresses to the back of patients with chronic low back pain (LBP).

Methods: Forty-six consecutive Patients suffering from chronic LBP were recruited. All patients were followed at the Soroka University Rheumatic Diseases Unit.  The patients were randomized into two groups: group 1 was treated with mineral-rich mud compresses, and group 2 with mineral-depleted compresses. Mud compresses were applied five times a week for 3 consecutive weeks. The primary outcome was the patient’s assessment of the overall back pain severity. The score of the Ronald & Morris questionnaire served as a secondary outcome.

Results: Forty-four patients completed the therapy and the follow-up assessments: 32 were treated with real mudpacks and 12 used the mineral-depleted packs. A significant decrease in intensity of pain, as described by the patients, was observed only in the treatment group. In this group, clinical improvement was clearly seen at completion of therapy and was sustained a month later. Significant improvement in the scores of the Roland & Morris questionnaire was observed in both groups.

Conclusions: The data suggest that pain severity was reduced in patients treated with mineral-rich mud compresses compared with those treated with mineral-depleted compresses. Whether this modest effect is the result of a “true” mud effect or other causes cannot be determined in this study. 

Objectives: To evaluate the performance of the C. DIFF QUIK CHEK COMPLETE^® assay, designed to simultaneously detect C. difficile-produced glutamate dehydrogenase (GHD) and toxins A and B.

Methods: Using the C. DIFF QUIK CHEK COMPLETE assay, the Tox A/B EIA, and polymerase chain reaction (PCR), we tested 223 stool specimens from hospitalized patients with antibiotics-associated diarrhea. Sensitivity and specificity, and positive and negative predictive values (PPV, NPV) were calculated for the C. DIFF QUIK CHEK COMPLETE test and the Tox A/B EIA against PCR

Results: The C. DIFF QUIK CHEK COMPLETE test had a sensitivity of 83.5% and specificity of 94.3% compared to PCR for Tox A/B, with 93.7% correlation (PPV 98.5%, NPV 91.7%). The Tox A/B EIA yielded corresponding values of 72.1% and 93.1%, with 85.6% correlation (PPV 85.1%, NPV 85.8%).

Conclusions: Given the importance of an early and appropriate diagnosis of Clostridium difficile-associated infection, the C. DIFF QUIK CHEK COMPLETE test may be of huge benefit to practitioners.

Objectives: To describe the exposures experienced by emergency responders to smoke, fire retardants and stress; the utilization of protective equipment; and the frequency of corresponding symptoms during and following the Carmel Forest fire.

Methods: A cohort of 204 firefighters and 68 police who took part in rescue and fire-abating activities during the Carmel Forest fire were recruited from a representative sample of participating stations throughout the country and interviewed regarding their activities during the fire and their coinciding symptoms. Unpaired two-sample t-test compared mean exposures and symptom frequency for firefighters and police. Chi-square estimates of OR and 95% CI are provided for odds of reporting symptoms, incurring injury or being hospitalized for various risk factors.

Results: Of the study participants, 87% reported having at least one symptom during rescue work at the Carmel Forest fire, with eye irritation (77%) and fatigue (71%) being the most common. Occupational stress was extremely high during the fire; the average length of time working without rest was 18.4 hours among firefighters.

Conclusions: Firefighters and police were exposed to smoke and occupational stress for prolonged periods during the fire. Further research is needed on the residual health effects from exposure to forest fires among emergency responders, and to identify areas for improvement in health preparedness.  

Objectives: To describe and identify clinical characteristics, prognostic factors and visual outcome in a group of patients with OGI in southern Israel.

Methods: We conducted a retrospective review of all cases of OGI examined in the ophthalmology department at Soroka University Medical Center, Beer Sheva, Israel, from 1996 to 2005. A total of 118 eyes with OGI were detected and analyzed statistically. We recorded demographic data, cause of injury, initial visual acuity (VA), associated globe morbidity and injuries, Ocular Trauma Score (OTS), surgical procedures, postoperative complications, and final VA.

Results: The mean age of the study group was 36.1 years and included 84% males. The median follow-up was 13.3 months (range 6–66 months). The annual incidence of open globe injuries was 3.1 cases/100,000. In 84 cases (71%) the mechanism of open eye injury was laceration. Most of the injuries were work related (45%). Bilateral injury was observed in two patients. An intraocular foreign body was observed in 45 eyes (38%). Primary surgical repair was performed in 114 eyes. Six patients (5.1%) had complications with post-traumatic endophthalmitis and 12 patients (10.1%) underwent evisceration or enucleation. Clinical signs associated with poor visual outcomes included reduced initial VA, eyelid injury, and retinal detachment at presentation.

Conclusions: In our study population the most important prognostic factors in open globe injury were initial VA, eyelid injury and retinal detachment.

Objectives: To study the effects of purified allicin on the cardiovascular system.

Methods: Spontaneously hypertensive rats treated for 6 weeks with a daily dose of 80 mg/kg/day of purified allicin added to their chow were compared to control rats that were fed regular chow. Weight, systolic blood pressure (SBP), triglycerides, cholesterol, insulin and adiponectin were measured at baseline and at the end of the study.

Results: Allicin had no effect on body weight whereas it reduced SBP significantly from 190 ± 7.5 mmHg to 168 ± 5.7 (P < 0.0001) and triglyceride levels from 96 ± 25 mg/dl to 71 ± 19 (P =0.009). Allicin had no effect on plasma cholesterol, insulin and adiponectin levels.

Conclusions: Allicin lowers blood pressure and triglyceride levels in spontaneously hypertensive rats. This effect is not mediated through weight loss.

Objectives: To determine the effect of the Dead Sea climatotherapy on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

Methods: A total of 119 patients participated in an observational prospective study carried out at the Deutsches Medizinisches Zentrum clinic, a medical skin care center specializing in climatotherapy. The patients completed questionnaires (Skindex-29) to quantify their quality of life at different time points: the day of arrival, the day of departure, and 3 and 6 months after the end of treatment.

Results: Marked improvement in the quality of life scores was measured between the time of arrival to time of departure and to 3 months after the end of treatment.

Conclusions: Dead Sea climatotherapy has a significant positive influence on the quality of life of patients with psoriasis vulgaris and psoriatic arthritis.

Background: Acute, as opposed to chronic, anterior uveitis is rarely associated with macular or optic nerve  edema. Nevertheless, mild changes may not be visible on examination.

Objectives: To implement non-invasive ocular coherence tomography (OCT) for obtaining quantitative and qualitative data in the assessment of changes in macular morphology and peripapillary retinal nerve fiber layers in eyes with acute anterior uveitis.

Methods: This retrospective case-control study was conducted in patients with unilateral acute anterior uveitis lasting for up to one month. Patients with evidence of other ocular disease or who had undergone intraocular surgery were excluded. We reviewed the charts of 14 consecutive patients who were diagnosed with acute unilateral anterior uveitis between 2007 and 2008 at the Tel Aviv Medical Center. Data on demographic details, ophthalmic examination, macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness (as demonstrated by OCT) were retrieved. Retinal and RNFL thickness was compared between the healthy fellow eye (control) and the uveitic eye in the central and four perifoveal quadrant regions, and RNFL thickness was compared in the mean and four quadrant values by Student’s t-test.

Results: We evaluated 28 eyes of 7 males and 7 females (mean age 37.7 years, range 20–65). The diagnoses were: idiopathic in five patients, ankylosing spondylitis in five, Crohn’s disease in one patient and reactive arthritis in one. Nine patients were HLA-B27 positive. The retina and the peripapillary NFL in each area were thicker in the uveitic eyes compared to the controls. The difference was statistically significant. There was no correlation between the differences in OCT values and patients’ demographic characteristics.

Conclusions: OCT demonstrated that eyes with acute anterior uveitis had thicker maculae and thicker peripapillary RNFL than controls. This finding suggests that even milder anterior uveitis may be associated with some degree of posterior segment manifestations.
