Background: Despite the continued progress of medicine, dealing with breast cancer is becoming a major socioeconomic challenge, particularly due to its increasing incidence. The ability to better manage and adapt to the entire care process depends not only on the type of cancer but also on the patient's sociodemographic and psychological characteristics as well as on the social environment in which a person lives and interacts. Therefore, it is important to understand which factors may contribute to successful adaptation to breast cancer.

Background: Cryptococcosis is one of the major causes of mortality among HIV patients worldwide. Though most often associated with late stage HIV infection/AIDS, a significant number of cases occur in other immunocompromised patients such as solid organ transplant recipients and patients with hematological malignancies. Immunocompromised patients are a heterogeneous group and their number increases constantly.

Objectives: Children with juvenile idiopathic arthritis (JIA) may be predisposed to serious pneumonia due to modern disease-modifying anti-rheumatic treatment. In this nationwide retrospective study with clinical data, we describe the pneumonia episodes among children with JIA.

Methods: Patients under 18 years of age with JIA and pneumonia during 1998-2014 were identified in the National Hospital Discharge Register in Finland.

Objectives: RA and its medication, especially TNF-α inhibitors, increase the risk of clinical tuberculosis (TB) infection. We aimed to investigate the clinical manifestations, incidence and temporal changes in TB occurring concurrently with rheumatic diseases (RDs) between 1995 and 2007.

Methods: We combined the register of the Social Insurance Institution of Finland and the National Infectious Disease Register to find adult patients with reimbursed DMARDs and with a TB notification between 1995 and 2007.

Objectives: To compare the incidence of pneumonia in children with juvenile idiopathic arthritis (JIA) to the aged-matched general population and to evaluate the use of anti-rheumatic medication among children with JIA and pneumonia.

Methods: The National Hospital Discharge Register collects data on ICD-diagnoses of hospital patients in Finland. From this register, patients with JIA under 18 years of age with pneumonia from 1999 through 2014 were identified.

Objectives: To describe the incidence and nature of bloodstream infections (BSI) among children with juvenile idiopathic arthritis (JIA) followed-up prospectively from disease onset.

Methods: The Social Insurance Institution's (SII) national register on individuals with reimbursement for medication of chronic diseases was used to identify children with JIA from 2004 through 2011 and their medications. The National Infectious Disease Register (NIDR) collects data of all blood culture positive samples from all microbiology laboratories in Finland.

Saccharomyces cerevisiae is increasingly recognized clinically, and repeated isolations from patients on a hematology unit in Turku, Finland, led to an epidemiologic investigation. Isolates were recovered from multiple body sites of 23 patients (n = 180) from 1994 to 1995 and from 29 patients (n = 45) from 1997 to 2002; these plus 2 from the hospital kitchen were identified as S. cerevisiae.

A 28-year-old woman with acute lymphoblastic leukemia developed fever and unilateral pleural based pulmonary infiltrate during prolonged chemotherapy induced neutropenia. CT-guided lung biopsy confirmed the diagnosis of pulmonary mucormycosis and liposomal amphotericin B therapy was started. A few days after the initial symptoms, the patient developed convulsions and a brain abscess was detected in computerized tomography and magnetic resonance imaging.

A real-time PCR method was developed and used to detect Aspergillus fumigatus mitochondrial DNA (mtDNA) in bronchoalveolar lavage (BAL) fluids and tissue biopsy specimens. The analytical sensitivity of the assay was one A. fumigatus conidium per reaction, and the assay was linear at least over 4 orders of magnitude above the detection limit.
