Anti-SOX-1 Antibody-Positive Paraneoplastic Limbic Encephalitis Diagnosed During Small Cell Lung Cancer Treatment.

Paraneoplastic neurological syndrome (PNS) mostly presents its symptoms prior to cancer treatment. We present a case of anti-Sry-like high mobility group box 1 (SOX-1) antibody-positive PNS diagnosed during the treatment of small-cell lung cancer (SCLC). A 65-year-old woman with a history of smoking and SCLC (T3N1M0) was hospitalized to receive chemo-radiation therapy.

Pneumococcal meningitis in a patient with severe COVID-19 on dexamethasone and tocilizumab: A case report.

Although various therapeutic agents have been tried for coronavirus disease-2019 (COVID-19) and evidence has accumulated, the risk of secondary infection is increased by underlying disease and immunosuppressive drugs. We report a case of pneumococcal meningitis in a patient with severe COVID-19 who was receiving dexamethasone and tocilizumab. The patient's symptoms improved with appropriate diagnosis and antimicrobial therapy, and she fortunately returned to society without any neurological sequelae of meningitis.

[A Case of Pneumocystis Pneumonia during Adjuvant Dose-Dense Chemotherapy for Breast Cancer].

A 47-year-old woman received adjuvant chemotherapy for breast cancer. On the 13th day of 4 courses of dose-dense AC therapy, she developed a fever. She was orally administered an antibioticfor febrile neutropenia treatment.

The prevalence of airway obstruction among Japanese HIV-positive male patients compared with general population; a case-control study of single center analysis.

Background And Objective: Previous studies have suggested that human immunodeficiency virus (HIV) infection and/or the airway colonization of Pneumocystis jirovecii (Pcj) impact on the progression of airway obstruction, such as chronic obstructive pulmonary disease (COPD). This study was aimed to evaluate the relationship between HIV infection, airway colonization of Pcj and airway obstruction in Japanese male patients.

Methods: Case-control study of 49 HIV-positive and 257 HIV-negative men were enrolled in this study.

[Two cases of mixed infection of malaria diagnosed by PCR method].

We here reported two Japanese cases of mixed infections of plasmodium species, whose DNAs were detected using the PCR test. One case was a 31 year-old male, who presented fever and fatigue, and had a travel history to Kenya, Cameroon and Indonesia. Smear test of his peripheral blood found the presence of Plasmodium vivax, while nested-PCR diagnosis detected the DNAs both P.

[A case of disseminated aspergillosis with smoldering adult T-cell leukemia].

The patient was 39-year-old male who had been administrated 20 mg of prednisolone for control of chronic eosinophilic pneumonia. He consulted the hospital with fever, headache and gait disturbance. The laboratory data of peripheral blood revealed a smoldering adult T cell leukemia.

[A case of pulmonary infection caused by Mycobacterium szulgai].

We report a case of pulmonary non-tuberculous mycobacteriosis caused by Mycobacterium szulgai. A thirty-nine-year-old man with no relevant significant past history underwent an annual medical check. His chest X-ray and CT scan showed an infiltrative shadow with a cavity in the right upper lobe.

[A case of loxoprofen-induced pneumonitis pathologically resembling hypersensitivity pneumonitis].

A 66-year-old woman was admitted to our hospital because of high fever, general fatigue, hypoxemia and liver dysfunction. Chest radiographs showed diffuse interstitial shadows in both lungs. We suspected drug-induced pneumonitis because of her history of drug administration for upper respiratory infection.
