Case Reports
Invasive fungal infections in patients treated with Bruton's tyrosine kinase inhibitors.
Bruton's tyrosine kinase (BTK) inhibitors are increasingly used in untreated and previously treated chronic lymphocytic leukaemia (CLL) patients. Invasive fungal infections (IFI) were rarely observed in patients treated for CLL in the pre-BTK era. In this article, we describe two patients with CLL who developed an IFI during treatment with the BTK inhibitor ibrutinib. The atypical presentation and the serious course of this complication are described.

With the introduction of conjugate pneumococcal vaccines, changes in causative serotypes and clinical presentations of Streptococcus pneumoniae infections are occurring. During the 2017-2018 winter, an unusual number of patients with a severe manifestation of pneumococcal disease was admitted to a tertiary care intensive care unit (ICU) in the Netherlands. We describe some of the cases in depth. Given our observed change in infecting serotypes and extreme clinical manifestations of pneumococcal disease, a systematic clinical registry of pneumococcal infections in the ICU may be a valuable addition to pneumococcal disease surveillance.

Review Case Reports
Monoclonal gammopathy with significance: case series and literature review.
Monoclonal gammopathy of undetermined significance (MGUS) is considered an asymptomatic precursor of malignant lymphoid disorders. This case series and literature review shows that these monoclonal gammopathies can cause significant morbidity. ⋯ Clinicians should be familiar with these consequences of monoclonal gammopathies. The term MGUS should only be used in patients without organ damage caused by monoclonal gammopathies.
