Case Reports[The Abdominal Ultrasonographic Appearance of Acute Phlegmonous Gastritis].
Phlegmonous gastritis (PG) is a nonspecific suppurative inflammation disease arising from the submucosal layer, and extending to the full thickness of the stomach. We herein report on a case of acute PG which was diagnosed with abdominal ultrasonography. A 64-year-old man presented at a hospital after having recently undergone pacemaker implantation for the treatment of complete atrioventricular block. ⋯ His clinical symptoms improved and the abnormal ultrasonographic examination findings thereafter returned to normal following the administration of antibiotics. PG should therefore be included in the differential diagnosis when encountering patients with acute abdomen. We experienced a rare case of acute phlegmonous gastritis and AUS was useful for making an early diagnosis.

Escherichia coli is the most commonly isolated bacterium in urinary tract infections, especially in acute uncomplicated cystitis. It is reported that fluoroquinolone-resistant E. coli is increasing. However, according to the guidelines for antimicrobial use published by the Japanese Associations for Infectious Diseases (JAID) and the Japanese Society of Chemotherapy (JSC) in 2014, the first line antimicrobial regimen for the treatment of acute uncomplicated cystitis is a 3-day regimen with fluoroquinolone. ⋯ Of the E. coli isolated from acute uncomplicated cystitis patients, 11.1% were levofloxacin-resistant strains. However, the clinical efficacy of antimicrobial treatment was relatively high (92.9%) in this study. The antimicrobial treatment for acute uncomplicated cystitis recommended by the guidelines published by the JAID and JSC was effective in the current situation.

Case Reports[A Case of Clinically Mild Encephalitis/encephalopathy with a Reversible Splenial Lesion due to Dengue Fever].
Clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) has been recently proposed as a clinical-radiological syndrome. Several causes of MERS have been reported including infectious diseases. We present herein on a case of MERS induced by dengue fever in a Japanese traveler. ⋯ It is hypothesized that dengue fever can induce MERS as dengue fever can cause increased endothelium permeability and hypo-sodium which have been proposed in the pathogenesis of MERS. However, there is currently limited evidence for this. Further research is recommended to demonstrate a causal association between dengue fever and MERS.

Case Reports[A rapidly progressive case of mediastinitis in which the patient developed inflammation of the soft tissue surrounding the pulmonary artery].
A 51-year-old male patient with no underlying illness developed a fever of 38-39 degrees C in June 2009. The fever persisted for 4 days and, because elevated hepatobiliary enzymes, leukocytopenia and thrombocytopenia were observed, along with chest CT findings of inflammation of the soft tissues surrounding the left pulmonary artery, the patient was admitted for further examination. Three days after admission, the patient's blood pressure rapidly decreased, resulting in respiratory failure. ⋯ The patient was ambulatory and was discharged after 24 days of hospitalization. Acute mediastinitis often follows a rapidly progressive and fatal course without specific symptoms. In the event of unknown infection following an aggressive course, as in the present case, acute mediastinitis must be considered with the goal of early diagnosis and treatment.

Case Reports[Plasmodium malariae malaria with more than a 4-month incubation period: difficult to distinguish from a relapse of Plasmodium vivax malaria].
We report herein on a case of Plasmodium malariae malaria with more than a 4-month incubation period. A 35-year-old Japanese man who first presented to our clinic with fever and history of travel to Papua New Guinea was suspected of having Plasmodium vivax malaria based on peripheral smear results. We admitted him and initiated treatment with mefloquine. ⋯ Therefore, the use of these drugs for prophylaxis will not be effective for prevention of malaria if its liver stage is longer than the duration of effective chemoprophylaxis. Although the incubation period of P. malariae is typically 13 to 28 days, it occasionally lasts for months or even years. Careful attention should be given to the possibility that P. malariae occasionally has a long incubation period even in the absence of the hypnozoite stage.
