A case of yellow nail syndrome with dramatically improved nail discoloration by oral clarithromycin.

An 80-year-old woman was admitted to our hospital with pneumonia and exacerbation of sinobronchial syndrome (SBS). She presented with yellow discoloration of the nail beds of all fingers and toes, and her nails were recognized as growing slowly. Chest X-ray revealed bronchiectasis in the bilateral lower lobe and bilateral pleural effusion. We diagnosed her as having yellow nail syndrome (YNS), based on the triad of yellow nails, lymphedema, and lung disease. After treatment with antibiotics [ampicillin/sulbactam and clarithromycin (CAM)] for pneumonia and SBS, her general condition improved, and the yellow nails disappeared in some fingers. When she was previously treated with 200 mg CAM for SBS, her yellow nails had not shown improvement. This time, her yellow nails improved after treatment with 400 mg CAM. The literature reports vitamin E, zinc, and topical corticosteroid plus active vitamin D3 to be effective in the treatment of yellow nails. Two studies have reported treatment for YNS using CAM, though they found a lack of efficacy. Thus, the present case is the first to report improved yellow nails using CAM alone. We conclude that not only SBS and lung disease but also YNS were improved by treatment with 400 mg CAM.

Pulmonary lymphoma developed during long-term methotrexate therapy for psoriasis.

Low dose weekly administration of methotrexate has been thought to be effective for both rheumatoid arthritis (RA) and psoriasis. However, there is a possibility that methotrexate therapy may be oncogenic. This report presents a case of pulmonary lymphoma developed during long‐term methotrexate therapy for psoriasis. Physicians should be aware that Epstein–Barr virus‐associated lymphoproliferative disorders that occur during treatment with methotrexate are not specific to patients with RA.

Asthmatic Attack Complicated with Takotsubo Cardiomyopathy after Frequent Inhalation of Inhaled Corticosteroids/Long-Acting Beta2-Adrenoceptor Agonists.

A 63-year-old man was transferred to our hospital because of an exacerbation of asthma. His symptoms deteriorated even after increasing the dose of inhaled corticosteroids/long-acting beta2-adrenoceptor agonists (ICS/LABA). He had no chest pain and an electrocardiogram revealed ST elevation. A coronary angiogram revealed a reduced left ventricular function with an apical ballooning pattern without coronary stenosis. He was diagnosed with Takotsubo cardiomyopathy. Catecholamine elevation due to acute asthma and an overdose of ICS/LABA may be triggers of this disease. We should remember that Takotsubo cardiomyopathy is a complication of asthma and that catecholamine plays an important role in its onset, although it is essential for asthma treatment.

A Comparison of Long-Term Anti-Inflammatory Effect of Two ICS/LABA Combination Inhalers; Fix-Dosed Maintenance Therapy with Budesonide/Formoterol and Salmeterol/Fluticasone

BACKGROUND The clinical usefulness of fixed-dose maintenance therapy with salmeterol/fluticasone (SFC) and budesonide/formoterol combination inhaler (BUD/FM) has been established, though evidence of the long-term anti-inflammatory effects of these 2 inhalers are limited. METHODS Patients with moderate persistent adult asthma who had received SFC 50/250μg bid with well-control status were recruited. After switching to 8-week therapy with fixed-dose BUD/FM 4 puffs (640/18μg) (phase-1), patients chose either SFC or BUD/FM. FeNO and ACT score were evaluated every 8 weeks until the end of the 52-week treatment period for both treatment groups (phase-2). RESULTS In total, 103 patients were examined: BUD/FM was chosen by 34 patients (BUD/FM group), while SFC was chosen by 23 (SFC group). Thirty-six received SFC consistently from the beginning of the study (control). Patients in the BUD/FM and SFC groups showed significant improvements in ACT scores and FeNO levels in phase-1; these beneficial effects persisted for 52 weeks in the BUD/FM group. On the other hand, in the SFC group, although the FeNO level decreased from 54.3 ± 26.4 ppb to 41.9 ± 18.3 ppb in phase-1, it increased to 54.5 ± 26.2 ppb, a level similar to the baseline prior to the beginning of BUD/FM therapy, at 8 weeks in phase-2, and remained at 50-odd ppb thereafter. CONCLUSIONS These results suggest that maintenance therapy with fixed-dose BUD/FM is a useful treatment option exerting an airway anti-inflammatory effect for a period as long as 1 year, even for asthmatics who could not accomplish total control with SFC.

A Case of Massive Hemoptysis with a Fungus Ball-like Shadow in an Old Tuberculosis Cavity That was Shown to be a Clot by Bronchoscopy

Development of aspergilloma is common in cases with a fungus ball-like shadow in cavities due to old tuberculosis. Some reports have shown that blood clots tend to appear as a fungus ball-like shadow. A 71-year-old man with a history of pulmonary tuberculosis presented with a fungus ball-like shadow in an old cavity and hemoptysis. There was no evidence of aspergillus infection on various examinations. We confirmed a blood clot and aneurysm of an artery under direct vision by bronchoscopy. A lateral thoracic artery aneurysm was detected by angiography. Transcatheter arterial embolization was performed. After treatment, the artery aneurysm disappeared.

Re-administration of abatacept for the control of articular symptoms of rheumatoid arthritis during anti-tuberculous therapy

This case report describes the re-administration of abatacept to successfully reduce the articularsymptoms of a patient with rheumatoid arthritisduring the intensive phase of anti-tuberculous therapy. A 75-year-old man developed active pulmonary tuberculosis during the administration of abatacept for rheumatoid arthritis. The patient experienced a paradoxical reaction and exacerbation of rheumatoid arthritis that caused us to discontinue the abatacept. Later re-administration of abatacept along with anti-tuberculosis treatment led to well-controlled rheumatoid arthritis without exacerbation of the tuberculosis. This case shows that re-administration of abatacept may be much safer than TNF inhibitor to treat patients who are infected with mycobacteria during thetreatment of immunological diseases such asrheumatoid arthritiswith biological agents.

Early-onset, Severe Chronic Obstructive Pulmonary Disease with Pulmonary Hypertension that was Likely Induced by Toluene Exposure

Early-onset pulmonary emphysema is uncommon and its pathogenesis is poorly defined. A 30-year-old man was admitted to our intensive care unit with severe respiratory failure. Besides smoking heavily since the 14 years of age, he had habitually inhaled organic solvents, such as toluene, in his adolescence. High-resolution computed tomography showed evident pulmonary emphysema throughout the lung fields. Based on the findings of right heart catheterization, he was diagnosed with an acute exacerbation of chronic obstructive pulmonary disease complicated with pulmonary hypertension. Heavy smoking from a young age and exposure to toluene were the suspected causes of the patients severe pulmonary emphysema.

Subinterlobular Pleural Location Is a Risk Factor for Pneumothorax After Bronchoscopy.

BACKGROUND: Pneumothorax is one of the most important complications after bronchoscopy. This study was conducted to determine the risk factors for post-bronchoscopy pneumothorax. METHODS: We retrospectively reviewed the medical records of 23 consecutive subjects who were diagnosed with iatrogenic pneumothorax after bronchoscopy between August 2010 and February 2014. Forty-six control subjects who did not develop pneumothorax after bronchoscopy were randomly selected. The factors affecting the occurrence of pneumothorax were determined by univariate and multivariate analyses. RESULTS: Among 991 patients who underwent bronchoscopy during the study period, 23 (2.3%) developed pneumothorax after bronchoscopy. Among these 23 subjects, 13 (57%) required chest tube drainage. Compared with the control group (46 randomly selected from 968 subjects who did not develop pneumothorax), the group that developed pneumothorax had a preponderance of women and had more target lesions located in the subpleural area (odds ratio [OR] 7.8, 95% CI 0.9–64), especially those that were close to the interlobular pleura (OR 5.1, 95% CI 1.6–16.1) and the left lung (OR 3.2, 95% CI 1.1–9.5). Multivariate analysis revealed that a subinterlobular pleural location of a lesion was a risk factor for pneumothorax (OR 4.8, 95% CI 1.1–20.4). CONCLUSIONS: Pneumothorax occurred significantly more frequently when bronchoscopy was performed for subinterlobular pleural lesions. Close attention and care should be taken during bronchoscopy, especially when target lesions are abutting the interlobular pleura.
