Hyperplasia of Lymphoid Follicles and Lymphangiectasia in the Parietal Pleura in Bucillamine-induced Yellow Nail Syndrome.

Yellow nail syndrome (YNS) pleurisy is often difficult to control, and pathological examinations have rarely been reported. We herein report a case of bucillamine-induced YNS in which histopathology of the parietal pleura revealed hyperplasia of the lymphoid follicles and lymphangiectasia. Even after the discontinuation of bucillamine, the pleurisy and lymphedema showed no change.

Cryptococcal Pleuritis Presenting with Lymphocyte-predominant and High Levels of Adenosine Deaminase in Pleural Effusions Coincident with Pulmonary Tuberculosis.

Co-infection with cryptococcus and tuberculosis has rarely been reported. We herein report a case of an 80-year-old man with cryptococcal pleuritis concurrent with pulmonary tuberculosis. He was admitted for progression of left pleural effusion and consolidation in the left upper lobe.

Pirfenidone-induced Eosinophilic Pleurisy.

The patient was a 69-year-old man with idiopathic pulmonary fibrosis who was taking pirfenidone. After 7 weeks of treatment, he suffered from left-sided eosinophilic pleurisy. Medical thoracoscopy was performed and the histopathological examination of the parietal pleura revealed the massive infiltration of eosinophils and lymphoid follicles.

[IMPACT OF COEXISTING NONTUBERCULOUS MYCOBACTERIA DURING THE TREATMENT OF PULMONARY TUBERCULOSIS].

Background: Nontuberculous mycobacteria (NTM) are often detected in patients undergoing treatment for pulmonary tuberculosis. This clinical status is thought to represent NTM disease, contamination, or colonization, but discriminating between these three conditions is difficult.

Purpose: We examined the clinical characteristics and pathogenicity of coexisting NTM among patients with pulmonary tuberculosis, as well as its impact on clinical practice.

[A case of drug-induced hypersensitivity syndrome caused by levofloxacin used for treating pulmonary tuberculosis].

The patient was a 27-year-old man with pulmonary tuberculosis, who was initially treated with isoniazid, rifampicin, ethambutol, and pyrazinamide. However, because of hepatic dysfunction and visual impairment, the four-drug therapy was switched to a three-drug regimen with isoniazid, rifampicin, and levofloxacin. At 9 weeks after the initiation of levofloxacin, the patient developed cervical lymphadenopathy, fever, systemic erythema, and hepatic dysfunction.

Fractionated administration of carboplatin/paclitaxel reduces neurotoxicity in patients with advanced non-small cell lung cancer.

The combination of carboplatin/paclitaxel is commonly used as chemotherapy for advanced non-small cell lung cancer. However, the relatively high incidence of neurotoxicity remains a problem. This study was undertaken to determine whether the fractionated administration regimen can reduce the neurotoxicity.

[A case of scrub typhus with lung involvement].

A 65-year-old-woman complained of lumbago from the end of March 2008. Three weeks later, she visited a local clinic because of high fever, and she was given a diagnosis of urinary tract infection. Although levofloxacin was given, her condition did not improve and she was referred to the urology department of our hospital.

[Legionnaires' disease with acute renal failure caused by Legionella pneumophilla serogroup 4].

A 77-year-old man who had fever and chest pain was admitted to a neighboring hospital on a diagnosis of pneumonia. Chest X-ray film finding deteriorated despite treatment with 2 g cefotaxime per day. Because of accompanying acute renal failure, he was transferred to our hospital.
