BACKGROUND: IgG4-related disease is a rare, clinical and pathologic disease entity of unknown etiology. Its main features are increased serum concentrations of IgG4 > 1,35 g/l, lymphocyte and IgG4+plasma-cell infiltration within tissues, fibrosis or sclerosis. The classical presentation of IgG4-RSD is pancreatitis which is combined with the involvement of biliary ducts in 74 percent of patients. Extrapancreatic manifestations include: abdominal or mediastinal lymphadenopathy; the involvement of salivary glands and lacrimal glands, kidneys, lung, retroperitoneum...

BACKGROUND: Delayed sternal closure (DSC) is commonly used to optimize hemodynamic stability after neonatal and infant heart surgery. We hypothesized that duration of sternum left open (SLO) was associated with rate of infection complications, and that location of sternal closure may mitigate infection risk. METHODS: Infants (age ≤365 days) undergoing index operations with cardiopulmonary bypass and DSC at STS Congenital Heart Surgery Database centers (from 2007 to 2013) with adequate data quality were included...

Pulmonary hyalinizing granuloma (PHG) is a rare disease characterized by single or multiple benign lung nodules mimicking lung neoplasma. Histologic analysis reveals homogenous hyaline lamellae, usually surrounded by collection of plasma cells, lymphocytes and histiocytes in a perivascular distribution. The clinical and radiological findings have been described in small series, but the long-term outcomes have rarely been reported. The objectives were to describe the clinical, radiological and outcomes of PHG in new cases and through a literature review...

Cryptococcus neoformans is an important opportunistic pathogen that causes serious mortality and morbidity in AIDS patients. Although its incidence has decreased with proper antiretroviral treatment (ART), it is still a major concern in areas with low socioeconomic HIV endemic countries with poor sources of therapy. In our country, pediatric HIV infection and so, HIV-related opportunistic infections are very rare. In order to pay attention to this unusual collaboration; herein, we presented a pediatric case who was diagnosed with HIV and disseminated cryptococcus infection concomitantly...

BACKGROUND AND OBJECTIVES: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the procedure of choice for the evaluation of mediastinal/hilar lymph node enlargements. Granulomatous inflammation of the mediastinal/hilar lymph nodes is often identified on routine histology. In addition, mediastinal lymphadenopathy may be present with undiagnosed infection. We sought to determine the usefulness of routine cultures and histology for infectious etiologies in a fungal endemic area when granulomatous inflammation is identified...

BACKGROUND Invasive candidiasis is a potential problem for patients receiving long-term immunosuppressive treatment. Psoriatic arthritis is one of many chronic diseases that can be successfully treated with immunosuppressive drugs, in spite of a documented and accepted risk for infectious complications. Critical awareness of possible infection must be part of the surveillance of such patients. CASE REPORT This is the case of a 68-year-old Norwegian male, treated with long-term immunosuppression for psoriatic arthritis, hospitalized with acute subcutaneous and mediastinal emphysema of unknown cause...

Endobronchial ultrasonography (EBUS) is a recent mini-invasive technique allowing transbronchial needle aspiration (TBNA) of mediastinal lymph nodes as well as peribronchial lesions. EBUS was initially developed for lung cancer mediastinal staging. Over the years, indications for EBUS have been progressively extended to the scope of inflammatory disorders, mediastinal lymphomas, and infectious diseases. Particularly in immunosuppressed patients, including HIV-infected patients, EBUS allows the diagnosis of several diseases that involve the mediastinum, avoiding invasive surgical explorations such as mediastinoscopy or thoracoscopy...

Mediastinitis occurs as a severe complication of thoracic and cardiac surgical interventions and is the result of traumatic esophageal perforation, conducted infections or as a result of lymphogenic and hematogenic spread of specific infective pathogens. Treatment must as a rule be accompanied by antibiotics, whereby knowledge of the spectrum of pathogens depending on the pathogenesis is indispensable for successful antibiotic therapy. Polymicrobial infections with a high proportion of anaerobes are found in conducted infections of the mediastinum and after esophageal perforation...

BACKGROUND: We report two cases of anisakiasis lesions that were initially suspected to be recurrence of gynecological cancer by positron emission tomography-computed tomography (PET-CT). Both cases were extragastrointestinal anisakiasis that is very rare. CASE PRESENTATION: The first case was a patient with endometrial cancer. At 19 months after surgery, a new low density area of 2 cm in diameter in liver segment 4 was found on follow-up CT. In PET-CT, the lesion had abnormal (18)fluoro-deoxyglucose (FDG) uptake with elevation in the delayed phase, with no other site showing FDG uptake...

Superior vena cava syndrome (SVCS) is a relatively common sequela of mediastinal malignancies and may cause significant patient distress. SVCS is a medical emergency if associated with laryngeal or cerebral edema. The etiologies and management of SVCS have evolved over time. Non-malignant SVCS is typically caused by infectious etiologies or by thrombus in the superior vena cava and can be managed with antibiotics or anti-coagulation therapy, respectively. Radiation therapy (RT) has long been a mainstay of treatment of malignant SVCS...

Lymphadenopathy is a common radiological finding in many thoracic diseases and may be caused by a variety of infectious, inflammatory, and neoplastic conditions. This review aims to describe the patterns of mediastinal and hilar lymphadenopathy found in benign diseases in immunocompetent patients. Computed tomography is the method of choice for the evaluation of lymphadenopathy, as it is able to demonstrate increased size of individual nodes, abnormalities of the interface between the mediastinum and lung, invasion of surrounding fat, coalescence of adjacent nodes, obliteration of the mediastinal fat, and hypo- and hyperdensity in lymph nodes...

Cytomegaloviruses may infect mammals via oronasal route. However, up till now it remains unclear how this exposure leads to a general infection and shedding. To address this issue, BALB/c female mice were oronasally inoculated with either the highly passaged murine cytomegalovirus (MCMV) Smith or the low passaged MCMV HaNa1. Virus titration showed a productive virus replication of both strains in the nasal mucosa from 1 dpi until the end of the experiment (14 dpi), in lungs from 5 until 14 dpi, and in submandibular glands from 7 until 14 dpi...

An asymptomatic mediastinal abscess was incidentally found in a 68-year-old male patient with a long history of hemodialysis. He had never had any symptoms but complained of chest pain only after the abscess ruptured into the right thoracic cavity. The abscess was discovered incidentally, when computed tomography was performed to determine the cause of his increasing ascites. Video-assisted thoracic surgery was performed to facilitate sufficient drainage and safe debridement. After the operation, we administered adequate antibiotics and continued irrigation of the thoracic cavity...
