Actinomyces israelii is usually responsible for the infections and causes chronic suppurative and granulomatous infections. The most common disease form is cervicofascial infection. Liver is involved in 5% of all actinomycosis infections. Liver involvement secondary to any primary infection site in the abdomen frequently occurs. In 15% of abdominal infections the liver is also involved. However, in very rare cases, a primary focus cannot be found, and these cases are called primary or isolated hepatic actinomycosis （IHA）. IHA which is frequently seen as a solitary abscess can be confused with a malignancy both clinically and radiologically.展开更多

The prognostic value of the RV/LV ratio in patients with idiopathic pulmonary arterial hypertension(IPAH) is still unknown. Methods We retrospectively enrolled 95 consecutive patients with newly diagnosed IPAH and 16 of them were reevaluated by echocardiography at 3-12 months following targeted therapy.Follow-up data were obtained by telephone interviews and review of the patients’ records.Results The RV/LV ratio was in parallel with the severity of World Health Orgnization(WHO) functional class and mean right atrial pressure.The RV/LV ratio was positively correlated with total pulmonary resistance(P P P 2 saturation(P P = 0.001),weight and absence of targeted therapy were independent predictors of death.No significant changes in the RV/LV ratio before and after targeted therapy were observed. A baseline RV/LV ratio≥0.84 or a further increase in the RV/LV ratio during targeted therapy indicated a poor prognosis. Conclusions The RV/LV ratio helps to assess the severity of IPAH and serves as an independent predictor of prognosis in patients with IPAH.展开更多
