OBJECTIVES: To control carbapenem-resistant Pseudomonas aeruginosa, we implemented a hospital-wide policy concerning the selective use of carbapenems based on the monitoring of P. aeruginosa isolates for susceptibility to five carbapenems using a customized dry plate method. In this study, we retrospectively investigated the outcome of our measures to control carbapenem-resistant P. aeruginosa. METHODS: To select effective carbapenems, 100 clinical isolates were collected, and the minimum inhibitory concentration (MIC) to 5 carbapenems (IPM/CS, MEPM, DRPM, BIPM and PAPM/BP) was monitored using a customized dry plate method from 2006 to 2013...

OBJECTIVES: Ischemia-reperfusion injury resulting in post-transplant lung dysfunction involves a complicated network of cytokines that has yet to be fully investigated. We analyzed temporal changes in cytokine levels in epithelial lining fluid (ELF) from the distal airways of a canine lung transplantation model. METHODS: Ischemic time was set to 18 hours to enhance lung injury in a left single-lung transplantation model. ELF was collected via bronchoscopic microsampling, a minimally-invasive technique allowing repeated sampling, hourly up to 5 hours after reperfusion started...

The first domestic outbreak of dengue fever in Japan since 1945 was reported in Tokyo in 2014. Meanwhile, daily mean summer temperatures are expected to continue to rise world-wide. Such conditions are expected to increase the risk of an arbovirus outbreak at the 2020 Tokyo Olympic Games. To address this possibility, the present study compared estimates of the risk of infection by dengue, chikungunya, and Zika viruses in urban areas. To compare the risk of infection by arboviruses transmitted by Ae. albopictus mosquitoes, the reproduction number for each of three arboviruses was estimated under the environmental conditions associated with the 2014 dengue outbreak in Tokyo, and additionally under conditions assuming a daily mean temperature elevation of 2° C...

The patient was a 32-year-old man with a previous history of bronchial asthma. He was admitted with chief complaints of dyspnea and skin rash associated with itching of the palms and soles of the feet, which began 2 weeks earlier. Because of the presence of cardiac failure and increase in the peripheral blood eosinophil count, eosinophilic myocarditis (EM) was suspected. His blood pressure gradually decreased and the patient went into cardiogenic shock. Therefore, endomyocardial biopsy was performed and was immediately followed by corticosteroid therapy and intra-aortic balloon pump (IABP) placement...

The patient was a previously healthy 23-year-old woman who made an outpatient visit to our hospital's Department of General Internal Medicine after developing pain and edema of the lower legs a week earlier. The patient was diagnosed with eosinophilic cellulitis (EC) based on an increased eosinophil count of 5,418/mm3 and the results of a skin biopsy of the lower leg that showed eosinophilic infiltration of the dermal tissue. Her condition improved after oral prednisone therapy. EC presents clinically as edema and eosinophilia...

BACKGROUND: Mirror feedback rehabilitation is effective in preventing the development of oro-ocular synkinesis following severe facial palsy. However, we do not have effective maneuvers to prevent the deterioration of oculo-oral synkinesis. We developed a new method of biofeedback rehabilitation using tape for the prevention of oculo-oral synkinesis. OBJECTIVE: The aim of the present study was to investigate the efficacy of taping feedback rehabilitation. METHODS: Twelve consecutive patients with peripheral facial nerve palsy who developed synkinesis were divided into 2 groups...

Pyoderma gangrenosum is an intractable disease of unknown cause involving recurrent ulcerative lesions on the skin, and may accompany ulcerative colitis, rheumatoid arthritis, leukemia, systemic lupus erythematosus, and other conditions. Here, we report a rare case of pyoderma gangrenosum in the thoracic abdomen following post-mastectomy reconstructive surgery. A 39-year-old presented at the hospital with a complaint of left papilla erosion. Skin biopsy at the site revealed invasive skin cancer, with Paget-like progression in the cancerous nipple and suspected malignancy of skin appendages...

Severe infection in patients who have lost splenic function is called overwhelming postsplenectomy infection (OPSI). Untimely treatment of patients with OPSI results in critical conditions with mortality rates as high as 50 %-70 %. For patients who undergo a splenectomy, vaccination is recommended for the prevention of OPSI. However, in Japan, the vaccination utilization rates are low. Herein, we report a case of OPSI caused by Streptococcus pneumoniae with a fulminant purpura resulting in multi-organ failure, which could be reversed by intensive care...

An 86-year-old woman was transported by ambulance after jumping from the second floor of a building. Upon arrival, the blood pressure was stable; however, computed tomography indicated the presence of an anterior mediastinal hematoma. Eight hours after arrival, the patient exhibited shock. The blood pressure increased with rapid infusion. Emergency angiography was performed. Extravasation from the musculophrenic artery, which branches off from the left internal mammary artery, was observed. Transcatheter arterial embolization was performed and bleeding was controlled...

Leiomyoma is one of the most commonly observed esophageal submucosal tumors, often appearing as a smooth-surfaced and semicircular protruded lesion. It sometimes grows toward the esophageal lumen and may be pedunculated in rare cases. We encountered a case of a pedunculated esophageal submucosal tumor diagnosed before treatment as a leiomyoma originating in the muscularis mucosae of a 68-year-old man. As the tumor arose in the muscularis mucosae, it could be safely resected via an endoscopic procedure. Only one case of pedunculated leiomyoma has been reported to date, and we herein report the second case, which was successfully treated by a minimally invasive endoscopic technique...

Currently, nivolumab (an anti-programmed cell death-1 receptor monoclonal antibody) is available for many types of advanced cancers in Japan. However, there have been few detailed case reports about endocrine-related adverse events of this therapy. Here, we report a patient with metastatic renal cell carcinoma who presented with secondary adrenal insufficiency following nivolumab therapy. Endocrinological assessment by rapid adrenocorticotropic hormone (ACTH) and corticotropin-releasing hormone (CRH) tests revealed that the patient's disorder was a secondary adrenal insufficiency due to pituitary dysfunction...

We present two cases of intestinal obstruction due to intersigmoid hernia that were diagnosed and treated laparoscopically. The first case was a 42-year-old woman with no surgical history. She was treated conservatively with the insertion of an ileus tube. Although the intestinal obstruction improved temporarily, since it subsequently worsened, laparoscopic surgery was performed, which revealed incarceration of the ileum in the intersigmoid fossa. Although there were no signs of necrosis after intestinal release, partial resection of the small bowel was performed before the hernial orifice was closed due to the evidence of serous damage...

Two breast cancer patients with a history of treatment for long-term rheumatoid arthritis (RA) had histological findings similar to histological changes seen in resected mammary gland specimens following neoadjuvant chemotherapy (NAC). The first patient was a 64-year-old woman who visited our hospital after feeling a lump in her left breast. The second patient was a 68-year-old woman who visited our hospital for an indentation in her left nipple. They were diagnosed with breast cancer following detailed examinations and underwent mastectomy...

INTRODUCTION: Metabolic Syndrome (Met S) is reported to be associated with sub clinical hypothyroidism (SCH). The aim of our study is to evaluate the role of SCH in association with adiponectin levels causing insulin resistance in metabolic syndrome. MATERIALS AND METHOD: We recruited 100 study subjects; out of which 50 were cases of Met S, which were further divided into two groups based on presence and absence of SCH and 50 were healthy controls. Serum insulin, serum T3, T4, TSH were measured by chemiluminisence based immunoassay and serum adiponectin was measured by ELISA...

OBJECTIVE: Inguinal ovarian hernias are common in young girls. Many articles in medical literature recommend early surgery for inguinal ovarian hernia because of the risk of torsion of the prolapsed ovary. However, since many irreducible herniated ovaries in newborn infants and during early infancy undergo spontaneous reduction by the age of 9 months, the policy at our institute is to obtain informed consent from the patient's family and then wait to perform surgery until after 9 months of age...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...
