Spontaneous Resolution of PCP on HRCT in a Patient with Renal Cell Carcinoma.

Tanaka Y, Saraya T, Kurai D, Ishii H, Takizawa H, Goto H.

Am J Case Rep. 2014 Nov 14;15:496-500. doi: 10.12659/AJCR.890947.

Abstract
Background Spontaneous resolution of Pneumocystis jirovecii pneumonia has rarely been reported.

Case Report A 59-year-old man presented to our hospital because of pyrexia (38°C) and shaking chills for 2 days.
He had a history of right nephrectomy due to renal cell carcinoma and left upper lobectomy for lung metastasis in the last 1.5 years.
Two months previously, he was treated with oral prednisolone (20 mg/day) plus the intravenous mTOR inhibitor, temsirolimus (25 mg/week),
for brain metastasis. On radiological examination, thoracic computed tomography showed diffuse ground glass opacities
spreading in bilateral middle to lower lung fields. Although transbronchial biopsy specimens and
bronchoalveolar lavage fluid demonstrated the presence of accumulation of black-colored
Pneumocystis jirovecii cysts in the lung, his chief complaints and radiological abnormalities disappeared completely
with no treatment. This case demonstrates a unique clinical presentation of Pneumocystis jirovecii pneumonia,
in that spontaneous resolution was noted on clinical and sequential radiological evaluations.

Conclusions Increasing numbers of cytotoxic drugs and biological therapies have emerged, and changes in the immune status
due to underlying diseases or administration of immunosuppressive drugs might affect the inflammatory process of
Pneumocystis jirovecii pneumonia, as in the present case.

Mycoplasma pneumoniae (Mp) is a leading cause of community acquired pneumonia. Knowledge regarding Mp pneumonia obtained from animal models or
human subjects has been discussed in many different reports. Accumulated expertise concerning this critical issue has been hard to apply clinically,
and potential problems may remain undiscovered. Therefore, our multidisciplinary team extensively reviewed the literature regarding Mp pneumonia,
and compared findings from animal models with those from human subjects. In human beings, the characteristic pathological features of Mp pneumonia
have been reported as alveolar infiltration with neutrophils and lymphocytes and lymphocyte/plasma cell infiltrates in the peri-bronchovascular area.
Herein, we demonstrated the novel aspects of Mp pneumonia that the severity of the Mp pneumonia seemed to depend on the host innate immunity to the Mp,
which might be accelerated by antecedent Mp exposure (re-exposure or latent respiratory infection) through up-regulation of Toll-like receptor 2 expression
on bronchial epithelial cells and alveolar macrophages. The macrolides therapy might be beneficial for the patients with macrolide-resistant Mp pneumonia
via not bacteriological but immunomodulative effects. This exhaustive review focuses on pathogenesis and extends to some therapeutic implications
such as clarithromycin, and discusses the various diverse aspects of Mp pneumonia.
It is our hope that this might lead to new insights into this common respiratory disease.

Fatal Disseminated Cryptococcosis Resembling Miliary Tuberculosis in a Patient with HIV Infection.

Shimoda M , Saraya T, Tsujimoto N, Kurai D, Takizawa H, Goto H.

Intern Med. 2014;53(15):1641-4. Epub 2014 Aug 1

Abstract
A 51-year-old man was transferred to our hospital due to acute respiratory failure that had progressed over four days.
A chest X-ray and thoracic computed tomography scan showed multiple faint micronodules randomly distributed throughout
both lungs with ground glass opacity, suggesting miliary tuberculosis or Pneumocystis jirovecii pneumonia with acute respiratory distress syndrome.
Six hours after admission, the patient died of septic shock. Later, the cryptococcal antigen titer was found to be markedly elevated (1/65,536),
with a positive result for anti-human immunodeficiency virus and a low CD4 cell count (12/μL).
The present case is reminder that disseminated cryptococcosis with HIV infection can be misdiagnosed as miliary tuberculosis based on radiological findings.

Viral respiratory infections may be associated with the virus-induced asthma in adults as well as children.
Particularly, human rhinovirus is strongly suggested a major candidate for the associations of the virus-induced asthma.
Thus, in this review, we reviewed and focused on the epidemiology, pathophysiology, and treatment of virus-induced asthma with special reference on human rhinovirus.
Furthermore, we added our preliminary data regarding the clinical and virological findings in the present review.

BMC Research Notes 2014, 7:303 doi:10.1186/1756-0500-7-303

Background
The presence of "mechanic's hands" is one of the clinical clues for collagen vascular diseases.
However, the exact relevance of "mechanic's hands" in collagen vascular diseases has not been well documented.
The aim of this study was to clarify the relevance of "mechanic's hands" to collagen vascular diseases
including various skin lesions and interstitial pneumonia.

Methods
A retrospective review of the medical records of patients with "mechanic's hands" at our hospital
between April 2011 and December 2012 was conducted. A PubMed search was also conducted using the term "mechanic's hands".

Results
Four patients in our institution and 40 patients obtained from PubMed who had "mechanic's hands" were identified.
The most frequent diseases were DM/amyopathic DM (n = 24, 54.5%) and anti-ARS syndrome (n = 17, 38.6%). In these patients,
the major skin lesions associated with "mechanic's hands" were periungual erythema (n = 23, 52.3%),
Gottron's sign (n = 17, 38.6%), heliotrope rash (n = 10, 22.7%), Raynaud's phenomenon (n = 9, 20.5%),
and anti-ARS syndrome (n = 17, 38.6%). Six cases (2 DM, 4 anti-ARS syndrome) had only "mechanic's hands".
Antibodies to anti-ARS (n = 24) were Jo-1 (n = 19), PL-7 (n = 3), OJ (n = 1), and PL-12 (n = 1).

Conclusion
The presence of "mechanic's hands" together with diverse skin lesions could be a clinical clue to the diagnosis of
lung involvement associated with collagen vascular diseases, especially in anti-ARS syndrome or DM/amyopathic DM.

2014年05月11日 | 医局のソファー


Breakthrough invasive Candida glabrata in patients on micafungin: A novel FKS gene conversion correlated with sequential elevation of minimum inhibitory concentration.

J Clin Microbiol. 2014 Apr 30. [Epub ahead of print]

Saraya T1, Tanabe K, Araki K, Yonetani S, Makino H, Watanabe T, Tsujimoto N, Takata S, Kurai D, Ishii H, Miyazaki Y, Takizawa H, Goto H.

Abstract
The Candida glabrata strains sequentially isolated from blood developed micafungin-resistance from <0.015 to 4 μg/mL of minimum inhibitory concentrations.
A novel mutation, 262 bp of FKS2 (containing F659del) was converted to the homologous region in FKS1, was identified in micafungin-resistant strains.

Sudden multiple fractures in a patient with sarcoidosis in multiple organs.

BMJ Case Rep. 2014 Apr 7;2014. pii: bcr2013201408. doi: 10.1136/bcr-2013-201408.

Sada M1, Saraya T, Ishii H, Goto H.

Abstract
A 30-year-old man who incidentally fractured his right olecranon and other multiple phalanges was admitted to our hospital.
He had a 2-year history of uveitis and bilateral hilar lymphadenopathy (BHL), and pulmonary sarcoidosis was diagnosed
from transbronchial lung biopsy. Right elbow arthrodesis was performed, and biopsied specimens showed non-caseating epithelioid cell granuloma,
suggesting osseous sarcoidosis. He was discharged uneventfully without further treatment,
but BHL had progressed with the appearance of lung parenchymal lesions 3 months later. At that time,
involvement of other organs was also noted on Gallium-67 scintigraphy, showing accumulations in BHL,
axillary and inguinal lymph nodes, enlarged liver and spleen and subcutaneous areas.
After initiation of steroid therapy, multiple organ involvement improved, and no further bone involvement has been recognised to date.
Osseous sarcoidosis complicated by bone fracture is an extremely rare presentation, but should be considered in patients with sarcoidosis,
especially when multiple organs are involved.

Intravascular large B-cell lymphoma

2014年03月19日 | 医局のソファー
Antemortem diagnosis with multiple random skin biopsies and transbronchial lung biopsy in a patient with
intravascular large B-cell lymphoma, the so-called Asian variant lymphoma


BMJ Case Reports 2014; doi:10.1136/bcr-2013-202661


Tomotaka Nishizawa, Takeshi Saraya, Haruyuki Ishii, Hajime Goto


Summary
A 59-year-old, previously healthy man presented to our hospital, with a 3-month history of high fever,
nocturnal sweating and exertional dyspnoea. Aggressive diagnostic procedures such as multiple random skin biopsies
and transbronchial lung biopsy (TBLB) led to an antemortem diagnosis of intravascular large B-cell lymphoma (IVLBCL),
which showed abundant CD20 atypical lymphocytes aggregated in lumina of small vessels. The 29 cases diagnosed with IVLBCL
during their lifetime by TBLB were reviewed. Their clinical features included respiratory symptoms
(hypoxaemia, dyspnoea and dry cough) and persistent fever. IVLBCL patients show various radiological patterns
(ground glass opacities, multiple centrilobular nodules, interlobular septal thickening, interstitial shadows
and thickening of bronchovascular bundles), suggesting lymphatic or haematological spread.
Antemortem diagnosis of IVLBCL is difficult, but a multidisciplinary approach, with aggressive multiple random skin biopsies
and/or TBLB, should be considered in patients with respiratory symptoms that are refractory to antibiotics or prednisolone treatment.
