Thromboembolic events in patients with influenza. A scoping review.

2022

Introduction: Influenza is an acute respiratory infection that usually causes a short-term and self-limiting illness. However, in high-risk populations, this can lead to several complications, with an increase in mortality. Aside from the well-known extrapulmonary complications, several studies have investigated the relationship between influenza and acute cardio and cerebrovascular events. Reviews of the thromboembolic complications associated with influenza are lacking. Objectives: the study aims to conduct a scoping review to analyze the epidemiological and clinical characteristics of patients suffering from influenza and thromboembolic complications. Materials and methods: A computerize…

Vitamin D Status and the Relationship with Bone Fragility Fractures in HIV-Infected Patients: A Case Control Study

2018

HIV-infected patients show high risk of fracture. The aims of our study were to determine the prevalence of vertebral fractures (VFs) and their associations with vitamin D in HIV patients. 100 patients with HIV infection and 100 healthy age-and sex-matched controls were studied. Bone mineral density was measured by quantitative ultrasound at the non-dominant heel. Serum osteocalcin and C-terminal telopeptide of collagen type 1 served as bone turnover markers. Bone ultrasound measurements were significantly lower in patients compared with controls (Stiffness Index (SI): 80.58 ± 19.95% vs. 93.80 ± 7.10%, respectively, p < 0.001). VFs were found in 16 patients and in 2 controls. HIV patie…

Clostridium baratii bacteremia associated with Kawasaki syndrome. First case report

2007

We experienced a case of a 3-year-old boy who presented signs and symptoms of Kawasaki syndrome. Two blood culture sets were processed by the hospital microbiology laboratory using a standard blood culturing system. The anaerobic bottles gave a positive result at day 3 after inoculation. The biochemical profiles produced by the RapID ANA II System showed that the organism was Clostridium baratii with a probability of 99%. Our case highlights the importance of C. baratii as a potential human pathogen and reports the associations with manifestations, which, to our knowledge, have not been previously described concomitantly with a clostridial infection.

Measles and Secondary Hemophagocytic Lymphohistiocytosis

2012

To the Editor: We found interesting the article by Lupo et al. about a case of fatal measles in an immunocompetent 29-year-old woman (Fatal measles without rash in immunocompetent adult, France; http://dx.doi.org/10.3201/eid1803.111300). Perhaps, however, the possible diagnosis of secondary hemophagocytic lymphohistiocytosis (HLH) should also have been considered in that setting. HLH is a potentially fatal hyperinflammatory syndrome characterized by histiocyte proliferation and hemophagocytosis. HLH may be inherited (i.e., primary, familial, generally occurring in infants) or may occur at any age secondary to infection, malignancy, or rheumatologic disease. Secondary HLH is determined accor…

An emergent infectious disease: Clostridioides difficile infection hospitalizations, 10-year trend in Sicily

2021

Abstract Background Clostridioides difficile is the most common cause of healthcare-associated diarrhoea worldwide and C. difficile infection is an emerging infectious disease. In the US, its rates are monitored trough an active surveillance system, but many European Union member states still lack this, and in Italy no epidemiological data on C. difficile infection are available except for a few single-centre data. Aim To provide data on the C. difficile infection incidence in Sicily (the biggest and 5th most populous region of Italy) during a 10-year period. Methods We revised all the regional standardized discharge forms between 2009 and June 2019 using the code ICD-9 00845 of the Interna…

Visceral leishmaniasis, hypertriglyceridemia and secondary hemophagocytic lymphohistiocytosis

2016

cytokines, an upregulation of adhesion molecules and MHC I and II molecules on mono/macrophages, and an expansion of inflammatory monocytes. This exaggerated inflammatory response is responsible for necrosis and organ failure and results in uncontrolled proliferation and phagocytic activity of histiocytes [2]. Hypertriglyceridemia (fasting, greater than or equal to 265 mg/100 ml) is one of the current diagnostic criteria for HLH [2]. Several studies link hypertriglyceridemia to inhibition of lipoprotein lipase (LPL) by tumor necrosis factor-α (TNF-α), and TNF-α is a powerful autocrine and paracrine regulator of adipose tissue [3]. Indeed, many different sources of intense and prolonged T-ly…

Use of sulesomab in the diagnosis of brucellar spondylitis.

2004

ABSTRACT Twenty-two patients with suspected brucellar spondylitis were investigated to evaluate the possible diagnostic role of Sulesomab, a 99m Tc-antigranulocyte antibody Fab' fragment. Sensitivity and specificity were compared with those of magnetic resonance imaging (MRI). Skeletal involvement was detected by MRI in 11 cases, while leukoscintigraphy indicated normal vertebral uptake in seven of these patients, increased uptake in two patients, and decreased uptake in two patients. Leukoscintigraphy of the 11 patients negative by MRI demonstrated increased uptake in two cases. The sensitivity and specificity of leukoscintigraphy were 27.2% and 81.1%, respectively. Based on these results,…

No findings of dental defects in children treated with minocycline

2004

Thanks to their broad antimicrobial spectrum, tetracyclines were found to be valuable for the treatment of many infections (10). Unfortunately, they irreversibly bind to calcifying tissues and are deposited along the incremental lines of dentine and enamel, causing defects and staining, from bright yellow to dark brown (3, 5, 8). According to the American Academy of Pediatrics, tetracyclines are not indicated for the treatment of common infections in children younger than 8 years of age. However, doxycycline (a tetracycline analogue) is recommended for treatment of Rocky Mountain spotted fever in children of any age (1). Minocycline has several advantages over other tetracyclines: it is bet…

Extended-spectrum beta-lactamase-producing and carbapenemase-producing Enterobacter cloacae ventriculitis successfully treated with intraventricular …

2014

SummaryWe present a case of post-neurosurgical ventriculitis caused by carbapenemase-producing Enterobacter cloacae successfully treated with intraventricular colistin. Enterobacter spp are intrinsically resistant to aminopenicillins, cefazolin, and cefoxitin due to the production of constitutive chromosomal AmpC beta-lactamases. Moreover, extended-spectrum beta-lactamase-producing Enterobacter spp have been identified in the USA and Europe, and carbapenems are considered the drug of choice in these cases. Our isolate was sensitive only to fosfomycin, tigecycline, and colistin, and 6 days of intravenous colistin had failed to eradicate the infection. This case provides clinical evidence to …

Scalp eschar and neck lymphadenopathy caused by Rickettsia massiliae

2013

To the Editor: Scalp eschar and neck lymphadenopathy is a common clinical entity that most frequently affects women and children during spring and fall. It is usually caused by Rickettsia slovaca and R. raoultii. Typical clinical signs are a scalp lesion at the tick bite site and regional, often painful, lymphadenopathy. Acute disease can be followed by residual alopecia at the bite site (1,2). Two designations have been proposed for this syndrome: tick-borne lymphadenopathy and Dermacentor-borne necrosis-erythema-lymphadenopathy (both have been associated with R. slovaca); however, the most generic and all-inclusive term is scalp eschar and neck lymphadenopathy. R. massiliae belongs to the…
