Background: The evidence on the use of dexamethasone implants in the treatment of Behçet’s disease (BD)-related uveitis is limited to a few cases. 

Objectives: To evaluate the efficacy of dexamethasone implants on ocular functional, morphological, and clinical parameters in BD patients with severe refractory uveitis. 

Methods: Five eyes from five BD patients were enrolled. A single intravitreal dexamethasone injection was applied to each eye. Best corrected visual acuity (BCVA), central macular thickness (CMT) assessed with optical coherence tomography, retinal vasculitis assessed by fluorescein angiography, vitreous haze score (Nussenblatt scale), intraocular pressure (IOP), and lens status (LOCS III, Lens Opacities Classification System III) were recorded at baseline and at 1, 3, and 6 month follow-up visits.

Results: At baseline, all eyes showed marked macular edema and 4/5 had concomitant active retinal vasculitis. Mean BCVA was increased from baseline at each control visit with a mean improvement of 0.26 ± 0.18 lines at 6 months follow-up. Mean CMT decreased from baseline at each control visit with a mean improvement at 6 months follow-up of 198.80 ± 80.08 µm. At the end of the study, none of the eyes showed macular edema and the mean CMT was 276.80 ± 24.94 µm. Retinal vasculitis resolved in all eyes. One eye experienced an IOP spike during treatment that resolved spontaneously, and one eye developed a clinically significant lens opacity at 6 months follow-up. 

Conclusions: Treatment with a dexamethasone implant in BD-uveitis and inflammatory macular edema was safe and effective as an additional treatment combined with systemic immunomodulatory drugs.

 

Background: Anti-glomerular basement membrane (GBM) antibody disease, or Goodpasture’s disease, is the clinical manifestation of the production of anti-GBM antibodies, which causes rapidly progressive glomerulonephritis with or without pulmonary hemorrhage. Anti-GBM antibody detection is mandatory for the diagnosis of Goodpasture’s disease either from the serum or kidney biopsy. Renal biopsy is necessary for disease confirmation; however, in cases in which renal biopsy is not possible or is delayed, serum detection of anti-GBM antibody is the only way for diagnosis.

Objectives: To assess the predictive value of positive anti-GBM antibodies in a clinical setting. 

Methods: Data from anti-GBM antibody tests performed at one medical center between 2006 and 2016 were systematically and retrospectively retrieved. We recruited 1914 patients for the study. Continuous variables were computed as mean ± standard deviation, while categorical variables were recorded as percentages where appropriate. Sensitivity and specificity of anti-GBM titers were calculated. Kaplan–Meyer analysis was performed, stratifying survival according to the anti-GBM antibody titers.

Results: Of the 1914 anti-GBM test results detected, 42 were positive, 23 were borderline, 142 were excluded, and 1707 results were negative. Male-to-female ratio was 1:1.2. Sensitivity of anti-GBM test was 41.2% while specificity was 85.4%. Concerning the Kaplan–Meyer analysis, overall survival was 1163.36 ± 180.32 days (median 1058 days). 

Conclusions: Our study highlights the lack of sensitivity of serological testing of anti-GBM titers. Comparing survival curves, the survival correlated with anti-GBM titer only in a borderline way. Because highly sensitive bioassays are not routinely used in clinics, renal biopsy is still pivotal for Goodpasture’s disease diagnosis.

 

Taxanes are often used in the treatment of many types of cancers. Side effects of docetaxel are not as well documented as paclitaxel, but both can cause pulmonary injury. We present a dramatic case of a patient being treated for prostatic adenocarcinoma with docetaxel who presented with interstitial pneumonitis and responded dramatically to the early treatment with corticosteroids. This case is important as it reveals the side effects of docetaxel administration without administration of other chemotherapeutic agents, and it illustrates the importance of early diagnosis and treatment of docetaxel-induced interstitial pneumonitis. Further research into the mechanism of the side effects of docetaxel is warranted.

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: Bowel ultrasound has several possible uses in inflammatory bowel disease (IBD), including the initial evaluation of suspected IBD, monitoring of therapeutic response, detection of relapse, and diagnosis of complications as well as of extra-intestinal manifestations. However, its use has been limited mainly to countries where it is performed by the attending physician. 

Objectives: To investigate the feasibility and sensitivity of bedside bowel ultrasound performed by a gastroenterologist for assessing disease activity and complications in IBD.

Methods: We performed a feasibility study to compare the results of bowel ultrasound examination with those of another cross-sectional imaging modality (computed tomographic enterography or magnetic resonance enterography) in Crohn's disease, or with colonoscopy in ulcerative colitis.

Results: Between May 2015 and March 2016, 178 bowel ultrasound examinations were performed in 178 patients with suspected or established diagnosis of IBD. In 79 cases the results of another cross-sectional imaging or endoscopic examination performed within 3 months prior to the ultrasound exam were available. The sensitivity for detection of intestinal bowel thickening (a surrogate of inflammation) was 90%, and for detection of Crohn's disease complications, namely bowel stenosis and inflammatory mass, was 94% and 75%, respectively.

Conclusions: Bowel ultrasound is a useful and feasible bedside imaging tool for the detection of inflammation and complications in IBD patients. Bedside bowel ultrasound can be a valuable non-invasive tool to assess disease activity and complications in IBD patients when performed by the attending physician.
