  • A 46 years old male showed radiologically a single cavitary nodular lesion in right upper lung, which extended to the regional chest wall. This finding has to be made into differential diagnosis of numerous pulmonary diseases including infections such as mycobacterial, fungal or bacterial, granulomatous diseases, and neoplasms. For the definite diagnosis, fine needle aspiration biopsy guided by biplane fluoroscopy was performed. The aspirates contained several sulfur granules, in the center of which many gram positive, filamentous organisms were compactly intermingled. Such a findings was compatible with pulmonary actinomycosis. Now the lesions is cleared out by medical treatment with amoxicillin for 3 months.

  • In this paper, we propose a subject-independent regression model to estimate systolic blood pressures (SBP) conveniently and continuously. There have been several researches on estimating SBP with pulse transit time (PTT) and they showed promising results. However, previous studies used only PTT as the estimation parameter, and their models were generated with just one person's PTT data which is not applicable to estimating other person's SBP. Therefore, we collected several additional biometric parameters with 202 healthy subjects. After statistical analysis of measured biometric parameters with SBP, we chose final estimating parameters including PTT to generate a multiple linear regression model for estimating SBP. Comparing the results of our study with approvable standards of automated sphygmomanometers developed by Association for the Advancement of Medical Instrumentation and approved by American National Standards Institute (ANSI/AAMI) indicates that our proposed method for continuously blood pressures monitoring gives an acceptable error.
