[Situations of Passive Smoking by Urine Cotinine Levels and Recognition of Passive Smoking in High School Students -Effectiveness of Smoking Prevention Education Using a Video Made by High School Students].

We investigated a situation of passive smoking and its damaging effects among high school students. Urine cotinine concentration was measured and quantified. Additionally, we evaluated the awareness of passive smoking and smoking regulations in high school students, and the educational effect on passive smoking using a questionnaire survey and educational videos produced by high school students.

Cohort Profile: The Network (GEN), a Network of Japanese Ophthalmological Epidemiology Studies.

Purpose: Japan has been known as a super-aged society, and ageing is a well-known risk factor for blinding eye diseases. However, epidemiological studies in ophthalmology are still scarce in Japan, and the sizes of the cohorts are relatively small. "Ganka-Ekigaku Network" (GEN, an acronym for the epidemiological network in ophthalmology in Japanese) is established to develop a capacity to boost each epidemiological study and enrich a potential inter-study collaboration to identify risk factors of visual impairment in aged society.

Clinical course and risk factors of recurrent corneal erosion: Observational study.

Recurrent corneal erosion (RCE) is a common disorder causing ocular pain, tearing, photophobia, and visual impairments. Various factors such as ocular trauma, ocular surgery, corneal dystrophy, contact lens wear, and diabetes mellitus (DM) can cause RCE. The purpose of this study was to determine the causative factors and clinical course of RCE.

Successful Treatment of Acute Fulminant Eosinophilic Myocarditis in a Patient with Ulcerative Colitis Using Steroid Therapy and Percutaneous Cardiopulmonary Support.

A 47-year-old man with ulcerative colitis was transferred to our hospital due to progressive dyspnea. Electrocardiography on admission showed ST elevation in leads II, III, aVF, and V5-V6. Coronary angiography revealed no remarkable coronary stenosis, and left ventriculography showed a depressed left ventricular ejection fraction (EF) of 23%.

Bilateral Iris Mammillations in Amblyopic Eyes without Oculodermal Melanocytosis or Neurofibromatosis.

Purpose: Iris mammillations are related to oculodermal melanosis and iris nevi. We report a rare case of bilateral simple iris mammillations without ocular melanosis or systemic neuronal disorders.

Case Report: A healthy 10-year-old Japanese girl was found incidentally to have bilateral iris mammillations while being treated for amblyopia.
