Many patients suffering from asthma or COPD have overlapping features of both diseases. However, a phenotypical approach for evaluating asthma-COPD overlap syndrome (ACOS) has not been established. In this report, we examined the phenotypes in patients with ACOS. Patients diagnosed with ACOS between 2011 and 2015 were identified and classified into four phenotype groups. Group A was composed of...

Introduction Both Sweet’s syndrome and pyoderma gangraenosum are neutrophilic dermatoses with abrupt onset of painful skin lesions. In Sweet’s syndrome systemic symptoms such as fever, headache and leucocytosis together with painful skin papules are often seen. Corticosteroid therapy is often sufficient treatment. Pyoderma gangraenosum is characterized by the development of painful ulcerative s...

the conduction system. In some PCCD patients, a conduction defect is documented from birth. Depending on the consequence of the mutation on the sodium channels, the phenotype may be progressive or congenital (Table).4 If the action potential generation and/or propagation is more severely impaired in the atria than in the ventricles in SCN5A mutation patients, the sinus node dysfunction caused b...

BACKGROUND The clinical phenotypes and underlying mechanisms of asthma-COPD overlap syndrome (ACOS) remain elusive. This study aimed to investigate a comparison of COPD patients with and without ACOS, focusing on inflammatory biomarkers, in an outpatient COPD cohort. METHODS We conducted a cross-sectional study analyzing prospectively collected data from the Ishinomaki COPD Network registry. ...

A patient presented with a mild polyneuropathy, developed a large intra-abdominal haemorrhage and died of cardiac arrest within a few days. Microscopic examination revealed a polyangiitis overlap syndrome (Fauci) with lesions in many organs, including the peripheral nerves and the heart. A myocarditis was considered to be the cause of death.

INTRODUCTION Asthma is a chronic inflammatory disease with multiple phenotypes. There is still a major gap in the understanding of its complex causality. Obstructive sleep apnea (OSA) is a common condition that has been implicated as a risk factor for asthma exacerbations. OBJECTIVES This study aims to characterize patients with the diagnosis of asthma and suspected OSA; identify the presence...

Differentiation of asthma and chronic obstructive pulmonary disease (COPD) in symptomatic patients has been extremely difficult clinically in many instances. This situation led to the formulation of the so-called “Dutch hypothesis” in 1961,1 cited by Christenson.2 The theory postulates that obstructive lung disease occur in a continuum, with asthma and COPD being expressions of the same disease...

Churg-Strauss syndrome (CSS) is a necrotizing vasculitis with extra-, peri-vascular eosinophilic infiltration. Chronic symmetric polyarthritis with the presence of rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody are the mainstay of rheumatoid arthritis (RA) diagnosis. Mononeuritis multiplex is a peripheral neuropathy involving more than 2 separate nerve areas. A 62-year-ol...
