[A CASE OF EOSINOPHILIC GRANULOMATOUS WITH POLYANGIITIS WITH SKIN LESIONS ASSOCIATED WITH PSORIASIS].

A 72-year-old woman who was undergoing treatment for bronchial asthma and psoriasis vulgaris experienced malaise three months earlier and visited our hospital on account of abnormal lung shadows. Chest computed tomography revealed ground-glass opacities in the peripheral lung fields and eosinophilia in the bronchoalveolar lavage fluid, which suggested eosinophilic pneumonia. Antineutrophil cytoplasmic antibody was negative.

[FREQUENCY OF IMAGING FINDINGS RESEMBLING MYCOBACTERIOSIS AND CHARACTERISTICS OF COMORBID PULMONARY NON-TUBERCULOSIS MYCOBACTERIOSIS IN THE PATIENTS WITH ALLERGIC BRONCHOPULMONARY MYCOSIS].

Objective: To clarify the frequency of imaging findings similar to mycobacterial infection and the characteristics of comorbid pulmonary non-tuberculosis mycobacteriosis in the patients with allergic bronchopulmonary mycosis (ABPM).

Subjects And Methods: Patients treated with ABPM at our hospital in the past 8 years were extracted from medical records, and 32 patients who met the clinical diagnostic criteria were retrospectively examined.

Results: The median age was 62.

[A CASE OF PROBABLE LATE-ONSET SYSTEMIC LUPUS ERYTHEMATOSUS WHERE THE INITIAL MANIFESTATION WAS A UNILATERAL PLEURAL EFFUSION].

A 74-year-old man developed with left pleural effusion and was suspected of benign asbestos pleural effusion and tuberculous pleurisy. Because of elevation of ADA level in the pleural effusion, diagnostic treatment for tuberculous pleurisy by anti-tuberculosis drugs was performed. However, right pleural effusion, cutaneous/mucosal lesions, leukocytopenia, and fever elevation occurred.

[A CASE OF SUMMER-TYPE HYPERSENSITIVITY PNEUMONITIS DURING IMMUNOSUPPRESSIVE TREATMENT FOR SYSTEMIC SCLEROSIS].

A 70-year-old woman undergoing long-term treatment for systemic scleroderma and secondary Sjögren syndrome developed fever during tapering of steroids. Chest CT showed centrilobular granular shadow and ground glass opacities. The pathology of transbronchial lung biopsy and the findings of bronchoalveolar lavage fluid were consistent with hypersensitivity pneumonitis and positive for anti-Trichosporon asahii antibody.

Mathematical model for histogram analysis of dynamic contrast-enhanced MRI: A method to evaluate the drug treatment response in rheumatoid arthritis.

Purpose: To evaluate the effectiveness of a mathematical model for histogram analysis of DCE-MRI in distinguishing responders from non-responders during RA drug treatment.

Method: Twenty-three consecutive RA patients with clinically active inflammation prospectively underwent DCE-MRI at baseline and after treatment. Manual segmentation of the enhanced synovium was performed on the last phase of DCE-MRI.

Peculiar blood flow profiles among placental chorionic villous vessels of an abnormally thick placenta in a case of systemic lupus erythematosus characterized using microvascular imaging.

We present a patient with systemic lupus erythematosus receiving long-term steroid therapy, who had myometrial thinning, markedly thickened placenta, and fetal growth restriction (FGR). Blood flow profiles of the myometrium, decidua and placental villous vessels (VV) were described using superb microvascular imaging (SMI) at 35 weeks' gestation. Images showed no decidual blood flow underneath the placenta sitting on a thin myometrium and sparse VV distribution and non-visualization of peripheral VV flow.

Regulation of matrix metalloproteinase-1 and alpha-smooth muscle actin expression by interleukin-1 alpha and tumour necrosis factor alpha in hepatic stellate cells.

Hepatic stellate cells (HSCs) are key players in liver fibrosis and regeneration via collagen degradation and synthesis. These phenomena involve inflammatory cytokines released from non-parenchymal liver cells such as Kupffer cells. Although the effects of individual cytokines on many cell types have been investigated in various conditions, such as inflammation and tissue fibrosis, investigating the effect of combined cytokines would further our understanding of the regulatory mechanisms in tissue fibrosis.
