[Surgical treatment for gall bladder cancer with a confluence stone-a case report].

The patient was a 71-year-old man. In September 2011, he experienced abdominal pain with high fever. Abdominal computed tomography (CT) diagnosed acute cholecystitis with a confluence stone (corlette classification type II).

[Prevalence and risk factors for silent lacunar infarct in white matter lesion--brain multiphasic screening].

To clarify difference of significant risk factors and that of prevalence with increasing age between white matter lesion (WML) and silent lacunar infarction (SLI), 946 brain check-up subjects were investigated. Twelve risk factors including age, sex, and hypertension were analyzed using multiple logistic regression analysis. A case of WML, which changed into infarction, was presented.

[Complete response of primary tumor in a case of advanced gastric cancer with liver metastasis treated by TS-1 plus divided administration of CDDP].

A 62-year-old female patient was hospitalized for general fatigue and appetite loss. Type 3 gastric cancer (moderate differentiated adenocarcinoma) with liver metastasis (S8) and direct invasion to the retro-peritoneal space and duodenal third portion was detected by endoscopic and radiographic examination. This case was judged to be unresectable from these findings.

[A case of advanced gastric cancer producing alpha fetoprotein with multiple liver metastases responding to TS-1 after TAE].

We report a case of advanced gastric cancer producing Alpha Fetoprotein (AFP) with multiple liver metastases in which TS-1 is effective. Prognosis of gastric cancer producing AFP is well known to poor. A 74-year-old female was admitted complaining of anemia.

Capillary filling analysis by digital subtraction angiography for vertebro-basilar insufficiency.

Vertebro-basilar insufficiency (VBI) is a vague clinical entity including several symptoms such as faintness, dizziness, vertigo. Millikan and Siekert reported a 'syndrome of intermittent insufficiency of basilar arterial system'. But vascular abnormalities responsible for such symptoms are often hardly diagnosed by conventional angiography, because vertebro-basilar artery systems have many kinds of anomalous congenital origins.

Prediction of arterial oxygen partial pressure from intrapulmonary venous admixture.

A short program was developed to predict the PaO2 at a given FIO2 by using arterial and mixed venous blood gas data obtained at an FIO2 of 1.0. Our program resolves Adair's equation and the shunt equation inversely, on the assumption that intrapulmonary venous admixture and the arteriovenous oxygen content difference remain constant during the study.

A SPECT study in internal carotid artery occlusion: discrepancies between flow image and neurologic deficits.

A SPECT (single photon emission computed tomography) study in internal carotid artery (ICA) occlusion was performed in 6 patients. The validity of iodoamphetamine (IMP) SPECT study in the evaluation of cerebral blood flow (CBF) or neurologic function is still controversial. In this study, the authors showed several cases in whom SPECT images of brain were not compatible with their neurologic deficits.
