Unusual cardiovascular complications of brucellosis presenting in two men: two case reports and a review of the literature

Introduction: Brucellosis is a zoonosis with worldwide distribution, which is particularly endemic in many countries of the Mediterranean basin. Cardiovascular complications of this disease, such as endocarditis, myocarditis and pericarditis, are very rare, with even fewer cases of myocarditis or asymptomatic pericardial effusion in the absence of concomitant endocarditis being reported. Case presentation: We report two cases of brucellosis in two Caucasian men, aged 17 and 34 years old, with myocarditis and asymptomatic pericardial effusion, respectively. Of note, neither patient had concomitant endocarditis. The disease was confirmed serologically and by blood cultures. Both patients recovered completely after receiving appropriate antibiotic treatment without any sign of relapse during a follow-up of 12 months. Conclusion: These two cases emphasize that in endemic areas Brucella can be considered as a potentially causative agent of idiopathic pericardial effusion or myocarditis, even in the absence of concomitant endocarditis. This possibility could be taken into account particularly in cases where contraction of brucellosis is possible, such as occupational exposure or consumption of unpasteurized dairy products. © 2011 Gatselis et al; licensee BioMed Central Ltd

Anemia and autoimmunity markers in an adolescent with Castleman disease

We describe herein the case of an adolescent girl with anemia non-responsive to oral iron, associated with low-grade fever, diminished appetite and fatigue. A palpable mass below the xiphoid was noted. Laboratory findings were consistent with anemia of inflammation. Direct antiglobulin test was positive without any other evidence of autoimmune anemia. Other autoantibodies, such as anti-thyroid and anti-nuclear antibodies, were also positive. After thorough investigation, Castleman disease was the most likely diagnosis on the basis of high serum interleukin (IL)-6 and the magnetic resonance imaging findings. 18 F-FDG positron emission tomography-computed tomography showed a localized hypermetabolic mass, which was resected. Castleman disease of plasma type was identified on histology. Hemogloblin and IL-6 gradually returned to normal, whereas positive autoantibodies became negative. This case emphasizes the need to investigate thoroughly for the underlying cause of anemia of inflammation and to include Castleman disease in the differential diagnosis, on the measurement of IL-6. © 2015 Japan Pediatric Society

Variation of cultured skin microbiota in mothers and their infants during the first year postpartum

Background/Objectives: The establishment of newborn skin flora depends on the ongoing skin maturation and the existence of potential microbial colonizers within the environment of the infant during a period of intense mother-infant physical interaction. This longitudinal study assessed culturable skin bacteria in the mother-infant dyad during the first year of life. Methods: A total of 17 mother-infant dyads were swabbed within 24 hours postpartum and at 3, 6, 9, and 12 months. Skin swabbing was performed on two anatomical areas per individual (mothers: chest-abdomen; infants: forehead-buttocks) and were incubated in five different solid culture media to optimize yield. Isolated bacterial species were identified to genus or species level using the API system (BioMeriéux, Marcy l'Etoile, France). Results: A total of 444 microbial strains were isolated belonging to 22 genera: 6 “frequent” (isolated from > 5% samples: S aureus, Proteus, Klebsiella, Pseudomonas, Enterobacter, and Enterococcus) and 16 “infrequent.” Isolated genera per individual peaked at 6 months postpartum for mothers and infants (P < 0.05). Enterobacter, Enterococcus, Klebsiella, and Pseudomonas isolation rates varied significantly as a function of sampling time contrary to the rather constant isolation rates of Proteus and S aureus. The rates of concordant isolation of the same microbial species within the mother-infant dyad tended to drop from birth to the end of the first year postpartum. Conclusions: Distinct variations in the isolation rates of skin commensals from specific anatomical sites of the mother-infant dyad indicate bidirectional microbial transmission. Increasing skin flora individuality of the growing infant was recorded, manifested by declining rates of concordant isolation of the same microbial species from mother and her infant. © 2019 Wiley Periodicals, Inc

Risk factors associated with HCV infection in semi-rural areas of central Greece

Background: Hepatitis C virus (HCV) appears to be endemic in most parts of the world, but there is considerable geographic variation. In order to assess the geographic distribution of HCV in Thessaly, in central Greece, we conducted a retrospective study in HCV-infected patients attending the Academic Liver Unit of Thessaly University from 1999 to 2003. We also investigated whether variation among regions could be attributed to differences in risk factors. Methods: We evaluated the records of 309 HCV patients whose origin and/or residence was in Thessaly. To identify risk factors that were independently associated with the place of birth and/or residence, adjusted odds ratios (OR) were calculated by logistic regression analysis. We also studied the medical records of 150 HCV-negative patients from the same areas in order to evaluate whether there are differences in risk factors reported by HCV-positive and HCV-negative patients. Results: We found three municipalities with a high HCV frequency. The use of non-disposable, multiple-use glass syringes for medical purposes in the past was the only potential risk factor more frequently identified in these areas than in other places (OR = 2.3; p < 0.05). This risk factor was significantly (p < 0.001) associated with older age of the infected patients. Conclusions: This study shows that the spread of HCV in the three regions may have occurred several years ago as a result of the use of multiple-use glass syringes. Differences in prevalence rates among different age groups, as well as among different areas, indicate the need for extensive studies to determine HCV epidemiology and to develop appropriate prevention programs. © 2006 European Federation of Internal Medicine

Descriptive epidemiology of chronic hepatitis B by using data from a hepatitis registry in Central Greece

Background: In Greece, there are few data on the epidemiological characteristics of HBV. Our aim was to study the epidemiological patterns of HBV in Central Greece and identify the possible differences in HBV prevalence (clusters) among areas inside this region using data from the hepatitis registry. Methods: The study was performed in Thessaly, one out of the thirteen regions of Greece and covers most of the part of Central Greece. A total of 921 HBV patients were registered in the hepatitis registry during the period 1999-2004 while 303 were randomly selected to be studied further using a detailed questionnaire on several epidemiological factors. Results: 187/303 patients (61.7%) classified as chronic inactive HBV carriers, 78/303 (25.7%) had chronic hepatitis B, 29/303 (9.6%) had HBV-related cirrhosis and 9/303 (3%) HBV-related hepatocellular carcinoma (HCC). The route of HBV transmission was vertical in 103 (34%), sexual in 46 (15.1%) and intrafamilial in 98 (32.4%). Folk remedies were identified as the predisposing risk factor for contracting HBV infection in 38 (12.5%), previous transfusion in 9 (3%) and unknown mode of transmission in 9 patients (3%). Alcohol abuse was the only independent factor (OR: 2.5; p=0.01) associated with the progression to cirrhosis-HCC. There were specific areas (clusters) inside Thessaly region with increased ratio of HBV infection; Vertical and sexual modes of transmission were more prominent in some of these areas. Conclusions: Vertical, intrafamilial and sexual modes of HBV transmission identified as the major routes of HBV infection in our study. We also identified cluster areas of HBV infection in Central Greece. Alcohol abuse is frequent among HBV patients and is acting as an effect modificator risk factor for the development of HBV-related cirrhosis and HCC. Extended population studies in Greece are needed to assess in detail the epidemiological patterns of HBV and evaluate control programmes. (C) 2008 European Federation of Internal Medicine.
