Cough is the most frequent presenting complaint in general practice and has an adverse effect on an individual's well-being. Understanding the causes of cough is critical for appropriate patient management. According to its duration, cough is classified as acute, subacute, and chronic. While acute respiratory infection is considered to be the major cause of acute cough, there is little evidence. We retrospectively assessed the prevalence of acute cough in all patients presenting with cough to the respiratory clinic of Japanese Red Cross Wakayama Medical Center from May 2018 to April 2019. We subsequently assessed the causes of acute cough, after stratifying patients with acute cough into two subgroups based on the chest X-ray findings. Among 685 patients (329 males; mean age, 61.8 ± 18.6 years) who presented with cough as a chief complaint, 274 (125 males; mean age, 57.6 ± 20.9 years) reported to have acute cough; chest X-ray abnormalities were detected in 113 of these patients. The most frequent cause of acute cough among 113 patients with chest X-ray abnormalities was pneumonia (55.8%), followed by lung cancer (9.7%) and pneumonia exacerbating asthma (7.1%). Among the 161 patients with acute cough without chest X-ray abnormalities, the most frequent cause was upper respiratory tract infection (57.1%), followed by asthma (23.6%) and cough variant asthma (6.2%). Cough is the most frequent presenting complaint in general practice. Infections are the most frequent causes of acute cough regardless of the chest X-ray findings. [ABSTRACT FROM AUTHOR]

Medical thoracoscopy, also called "local anesthetic thoracoscopy" and "pleuroscopy," is a minimally invasive single‐port endoscopic technique that provides direct visualization of the pleural surfaces and channels to conduct diagnostic and therapeutic procedures. However, this technique is not helpful when substantial fibrous adhesions exist. We reported the first case of intrapleural urokinase directly under medical thoracoscopy for the diagnosis of malignant pleural mesothelioma with severe multiloculated pleural effusions in 2019. This is the second report regarding the efficacy of intrapleural urokinase directly under medical thoracoscopy for the diagnosis of multiloculated pleural effusions. Urokinase‐induced intrapleural fibrinolysis, which removed the fibrous septa, consequently improved the field of view under endoscopy within only 10 min. Fibrinolytic effect appeared very rapidly. This technique is available for tuberculous pleurisy with severe multiloculated pleural effusion. [ABSTRACT FROM AUTHOR]

Purpose: To study the possibility that changes in high-sensitivity C-reactive protein (hs-CRP) may be a predictor of forced expiratory volume in 1 second (FEV1) decline over time in adult asthmatic subjects., Methods: Subjects with adult-onset asthma with no smoking history underwent complete medical evaluation at Yoka Public Hospital in both 2005 and in 2008 (n = 26). We analyzed the correlation between hs-CRP levels and FEV1 changes over time, in relation to whether or not they received inhaled corticosteroid (ICS) therapy. We also measured the cardio-ankle vascular index (CAVI), intima-media-thickness (IMT), and fraction of exhaled nitric oxide (FeNO) of hospital staff members who acted as non ICS asthmatic subjects (n = 11), and also performed multiple regression analysis., Results: In the non-ICS asthmatic subjects group (n = 19), there was a significant correlation between log (hs-CRP) levels and FEV1 changes (R = -0.734, P < 0.001). After controlling for age, body mass index, CAVI, IMT, and FeNO, hs-CRP was found to be an independent risk factor., Conclusion: Hs-CRP levels are a predictor of FEV1 decline over time in adult-onset asthmatic patients with no smoking history, who are not receiving ICS therapy.

Chest CT on admission of a 58-year-old woman with bloody sputum showed a mass shadow at the hilum of the right lung suggesting invasion to the mediastinum, and contralateral mediastinal lymph node (#6) metastasis. Bronchial brush cytology yielded a diagnosis of small cell lung cancer (SCLC). The clinical stage was T4N3M0, stage IIIB, limited disease (LD). On admission, her platelet count was only 40 x 10(3)/microl. Blood biochemistry and bone marrow puncture revealed immune thrombocytopenic purpura (ITP). We speculated that she had secondary ITP (ITP-like syndrome) associated with cancer. Only 11 cases of lung cancer with secondary ITP have ever been reported, 4 cases of which attained complete response of cancer and complete remission of ITP by anti-cancer therapy. Therapeutic procedures employed were surgery in 3 cases of adenocarcinoma and a high dose chemotherapy (HDC) with autologous peripheral blood stem cell transplantation (APBSCT) in 1 case of SCLC. In the present case, concurrent chemoradiotherapy (four cycles of cisplatin/etoposide (PE) combined with 45Gy of thoracic radiotherapy) was performed, which resulted in a complete response of SCLC and a complete remission of the secondary ITP. This is apparently the first report of successful treatment of SCLC with secondary ITP by standard chemoradiotherapy. In a SCLC patient with ITP-like symptoms, treatment for SCLC may simultaneously resolve the ITP-like symptoms.

A 63-year-old man who had general malaise and dyspnea on effort, was admitted to our hospital. Chest X-ray film on admission showed left pleural effusion. Chest and abdominal CT after left chest drainage revealed left pleural thickening, mediastinal lymph node swelling, multiple lung nodules, osteolytic change of the left 4th rib, and multiple liver tumors. Right pleural effusion and ascites was also recognized. Cytology of the left pleural effusion suggested malignant mesothelioma. He had a skin tumor on his anterior chest. Biopsy revealed metastasis of malignant epithelioid mesothelioma. Upper gastrointestinal endoscopy showed a duodenal tumor and colonoscopy showed a cecal erosion. Endoscopic biopsy revealed metastases of malignant mesothelioma identical to the skin tumor. Because of the left pleural thickening, the primary site was considered to be in the left pleura. Here we report a case of malignant pleural mesothelioma (MPM) with multiple distant metastases to the duodenum, cecum, skin, lung, liver, and rib. Gastrointestinal metastases of MPM detected by endoscopic biopsy are very rare. Only one case of cecal metastasis has ever been reported.
