To expand the role of medical technologists in response to legal reforms made in 2015, our hospital devised a system where all laboratory staff would support physicians in clinical tasks and engage in team medicine. To secure staffing for this system, we had all our laboratory staff participate in a seminar specified by the Ministry of Health, Labour and Welfare, which allowed us to place staff in rotating shifts and thus have dedicated staff for influenza testing continually available in the emergency department on days when the hospital is closed for appointments. We decided that these medical technologists would be responsible for all influenza testingrelated tasks beginning with collecting samples from patients with fever suspected of having influenza to reporting test results. This change significantly improved work efficiency and testing turnaround time, and was viewed favorably by physicians, nurses, and hospital administrators.

Objective: The utility of topotecan monotherapy for relapsed small-cell lung cancer (SCLC) after failure of amrubicin monotherapy has not been evaluated. We aimed to investigate the efficacy and safety of topotecan monotherapy in patients with relapsed SCLC after amrubicin monotherapy.Patients and Methods: We retrospectively analyzed data from 16 patients with relapsed SCLC who were treated with topotecan monotherapy after amrubicin monotherapy at our hospital.Results: The response rate, progression-free survival, and overall survival were 0%, 32.5 days (95% confidence interval [CI] = 18–51), and 112 days (95% CI = 55–267), respectively. The most common adverse events (grade ≥3) were leukopenia (31.3%) and thrombocytopenia (31.3%), followed by anemia, anorexia, edema, and lung infections.Conclusion: The efficacy of topotecan monotherapy for relapsed SCLC after amrubicin monotherapy is inconclusive. Therefore, further studies are warranted.

Heberden's and Bouchard's nodes are clinical manifestations of osteoarthritis of the interphalangeal joints. Heberden's nodes typically affect the distal interphalangeal (DIP) and Bouchard's nodes, the proximal interphalangeal (PIP) joints of a fingers in patients with osteoarthritis. We describe osteoarthritis of the interpha­langeal joints in 3 women who were successfully treated with sokeikakketsuto. Case 1 : A 58-­year-­old woman presented with pain in the DIP joint of her left middle finger and was diagnosed with a Heberden's node. Case 2 : A 60­-year­-old woman presented with pain in the DIP joint of her left ring finger and was diagnosed with a Heberden's node. Case 3 : A 37­-year-­old woman presented with pain in PIP joint of her left ring finger and was diagnosed with a Bouchard's node. All women were successfully treated with sokeikakketsuto. In conclusion, sokeikakketsuto is a useful Kampo medication to treat mild-­to-­moderate pain secondary to bone, joint, or spinal conditions, as well as non-­steroidal anti­inflammatory drugs.

Carpal tunnel syndrome is a common condition caused by compression of the median nerve. Patients usually present with numbness and pain along the distribution of the median nerve in the hand. We report 2 cases of carpal tunnel syndrome successfully treated with kakkonto after their pattern diagnosis. We treated a 57-year-­old women and a 59-­year-­old man. Two patients presented with hand pain and numbness and were diagnosed with carpal tunnel syndrome. Kakkonto treatment was successfully in two cases. We observed that median nerve compression persisted in these patients even after disappearance of numbness and pain ; therefore, we recommended operative management. The 2 patients underwent an operation for carpal tunnel syndrome. Kakkonto can be considered useful palliative treatment before considering operative management for numbness and pain in the patients with carpal tunnel syndrome.

A 38-year-old man was admitted to our hospital with fever and skin rash, and he was diagnosed as having dermatomyositis. He was treated with anti-inflammatory steroid and immunosuppressive agents. On hospital day 48, chest computed tomography (CT) revealed a nodule measuring approximately 2 cm in size in the lower lobe of the right lung (S9). Bacterial and/or fungal infection was suspected, but there was no response to antibiotic or antifungal treatment. A week later, repeat chest CT revealed the tumor now measuring approximately 6 cm in size in the lower lobe of the right lung. We performed bronchoscopy, and bacteriological examination of the transbronchial biopsy specimen revealed pulmonary tuberculosis. Interferongamma release assay (IGRA) before the initiation of immunosuppressive treatment was negative, so we did not administer treatment for latent tuberculosis infection. He was, however, treated with isoniazid, rifampicin, ethambutol, and pyrazinamide for 9 months, following which radiological features improved gradually. Here we describe in detail this rare case of a negative IGRA result before immunosuppressive therapy in a relatively young Japanese man who went on to develop active tuberculosis with a rapidly-growing pulmonary lesion during hospitalization.

We present two cases of night sweats due to eiefuwa (deficiencies of nutrients and defenses) that were suc­cessfully treated with Kampo medicine. Case 1 was that of a 64-­year-­old man with perspiration during sleep and slight fever, and Case 2 was that of a 78­-year-­old man with perspiration during sleep and common cold­-like symptoms. Case 1 was administered with saikokeishito, and his symptoms quickly disappeared. Case 2 was administered with common cold drugs and saikokeishito initially, but the treatment was ineffective. Therefore, keishito was administered, and the patient's symptoms disappeared within 2 days. Sweating and common cold-­like symptoms were successfully treated with Kampo medicine for the diagnosis of eiefuwa. Further, we discuss the various descriptions of eiefuwa in the literature.

Poor eating is a life-threatening condition in senior citizens. Herein, we report a case of poor eating due to stomach yin deficiency (wei yin xu), which was successfully treated with bakumondoto. The patient was a 91-year-old woman who expected treatment for her poor food intake. She was diagnosed as poor eating with stomach yin deficiency and was administered with bakumondoto, which increased her food intake and weight. To treat poor eating with Kampo medicine, rikkunshito and various other Kampo drugs are commonly used. In this case, bakumondoto, which is usually used for respiratory diseases such as dry cough, was effective. Bakumondoto is useful for stomach yin deficiency of poor eating.

A 68-year-old man was admitted to our hospital with complaints of fatigue, polyuria, and loss of appetite, and was diagnosed with diabetic ketosis. Chest and abdominal computed tomography (CT) showed a pulmonary tumor on the right S3 and multiple liver tumors. Blood chemistry revealed elevated levels of amylase and hepatobiliary enzymes. Pathological examination of a biopsy specimen from the liver tumor showed a small cell carcinoma. Based on the imaging and pathological findings, we made a diagnosis of extensive disease small-cell lung cancer (ED-SCLC), cT1aN3M1b (HEP, ADR). Treatment with carboplatin and etoposide evoked partial response and the serum level of amylase decreased. Immunohistochemical staining of liver biopsy specimen was positive for amylase, leading to a diagnosis of SCLC with amylase production. About 22 months after the diagnosis of SCLC, he was admitted to our hospital with fatigue, muscular weakness, edema, and hyperpigmentation. Laboratory findings showed elevated serum levels of hepatobiliary enzymes, adrenocorticotropic hormone (ACTH), and cortisol, and a decreased serum potassium level. Urinary potassium level was elevated. Pituitary magnetic resonance imaging showed a normal morphology. We made a diagnosis of SCLC complicated by Cushing’s syndrome. We report this rare case of SCLC with amylase and ACTH production, which was detected in the course of treatment of SCLC.

In patients with epidermal growth factor receptor (EGFR) mutation-positive lung cancer (LC) who have acquired resistance to first and/or second-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs), detection of EGFR T790M (T790M) mutation is essential before administration of osimertinib. Tissue sample is the main specimen used to detect the T790M mutation, and so cell block preparation using pleural or pericardial fluid should be considered. The utility of body cavity effusion cell block methods in T790M mutation detection have not yet been fully evaluated. This study aimed to evaluate the clinical background and treatment course of LC patients harboring the T790M mutation by using body cavity effusion cell block methods at our hospital. All patients were treated with first and/or second-generation EGFR-TKIs and had developed malignant pleural or pericardial fluid as a result of progressive disease. T790M mutation status was evaluated using body cavity effusion cell block method in 9 patients, from April 2016 to August 2017. We retrospectively evaluated the clinical characteristics and treatment course of these 9 patients (3 males and 6 females; median age 76 years). At the first diagnosis of LC, 7 patients had stage IV cancer; 4 patients were diagnosed by bronchial fibroscopy and 3 were diagnosed from pleural fluid examination. Regarding EGFR mutation, 3 and 6 patients carried the exon 19 deletion and L858R mutation, respectively. Median time interval between the first diagnosis of LC and T790M mutation evaluation was 30.8 months; 7 patients were diagnosed with positive T790M mutation by using body cavity effusion cell block methods. The T790M mutation was highly detected by examination of body cavity effusion cell blocks. Further evaluation is necessary with respect to variations in T790M detection rate based on the specimen collection site and/or progressive disease pattern in different patients.
