Congenital Cardiac Defects, Such as Eustachian Valve, May Increase the Risk of Cryptogenic Stroke: A Case Report

Eustachian valve is an embryonic endocardial heart structure;after birth it becomes an embryogenic residue and its persistance in adult life is unusual. The literature reports some cases of association between Eustachian valve and PFO and is known that the prominent Eustachian valve can represent a way facilitating systemic embolism.Several studies also investigated the role of Eustachian valve in the pathophysiology of both migraine and cerebral embolism. In addiction is known how Eustachian valve may increase the risk of endocarditis, which mostly affects intravenous drug abusers or those with implanted medical devices or central venous catheters. The most commonly identified organism is Staphylococcus aureus (approximately 53% of cases). We present a case of a 46-year-old woman with known migraine. She was hospitalized in Stroke Unit for a cryptogenic stroke with a right-to-left shunt detected with transcranial doppler ultrasound with “bubble test” and a patent foramen ovale with right-to-left shunt with a fenestration of atrial septum and a voluminous Eustachian valve detected with transesophageal echocardiography;she developed fever with a blood cultures positive for methicillin-resis- tant Staphylococcus aureus (MRSA), even if without evidence of endocarditis vegetations. In summary, the objective of our paper is to present an example of a correlation between the persistence of the Eustachian valve with bothcryptogenetic stroke, possible valve infection and migraine.

Body composition changes after transjugular intrahepatic portosystemic shunt in patients with cirrhosis

AIM:To investigate the effect of transjugular intra-hepatic porto-systemic shunt (TIPS) on malnutrition in portal hypertensive cirrhotic patients.METHODS: Twenty-one patients with liver cirrhosis and clinical indications for TIPS insertion were investigated before and 1, 4, 12, 52 wk after TIPS. For each patient we assayed body composition parameters [dry lean mass, fat mass, total body water (TBW)], routine liver and kidney function tests, and free fatty acids (FFA). Glucose and insulin were measured for the calculation of the homeostasis model assessment insulin resistance (HOMA-IR); liver function was measured by the galactose elimination capacity (GEC); the severity of liver disease was graded by model for end-stage liver disease (MELD).RESULTS: Porto-systemic gradient decreased after TIPS (6.0±2.1 mmHg vs 15.8±4.8 mmHg, P<0.001). Patients were divided in two groups according to initial body mass index. After TIPS, normal weight patients had an increase in dry lean mass (from 10.9±5.9 kg to 12.7±5.6 kg, P=0.031) and TBW (from 34.5±7.6 L to 40.2±10.8 L,P=0.007), as well as insulin (from 88.9±49.2 pmol/L to 164.7±107.0 pmol/L,P=0.009) and HOMA-IR (from 3.36%±2.18% to 6.18%±4.82%,P=0.023). In overweight patients only FFA increased significantly (from 0.59±0.24 mmol/L to 0.93±0.34 mmol/L, P=0.023).CONCLUSION: TIPS procedure is effective in lowering portal pressure in patients with portal hypertension and improves body composition without significant changes in metabolic parameters.

Benign intratesticular schwannoma:a rare finding

Schwannoma is a peripheral nerve tumour, occasionally located in the genitourinary tract. We described an extremely rare case of intratesticular neurinoma in a 79-year-old patient. （Asian JAndrol 2006 Jan; 8： 101-103）

Retrospective descriptive analysis of the physiological kinetics of prostate-specific antigen in men older than 75 years

Several studies have compared prostate-specific antigen （PSA） kinetics in men with and without cancer, but there has been no adequate analysis of the longitudinal variation in PSA. The aim of this study was to assess the fluctuations in PSA in a cohort of elderly men in an attempt to define a physiological pattern of PSA kinetics. We searched a specific cohort of patients aged 〉 75 years and with PSA value 〈 2.0 ng mL^-1. A history of all PSA values over the past 10 years was compiled for each patient to create a database of patients fitting the following criteria： （1） minimum of five PSA measurements, （2） over at least 5 years. Exclusion criteria were： （1） PSA 〈 0.2 ng mL^-1 at each measurement and （2） having had more than one PSA test per year. In all, 1 327 patients （mean age： 78.52 years） fit the inclusion criteria. The mean variation from the first to the last PSA test was 0.05 ± 0.43, with a mean follow-up of 6.79 ± 1.71 years. Over the same period, the mean fluctuation from the lowest to the highest PSA value was 0.04 ± 0.55 （P = 0.925）. The mean annual PSA velocity （PSAV） was calculated by dividing the mean variation from the first to the last PSA test by the number of years of observation for each patient and was set at 0.0104 ± 0.1050. Concluding, in a large-scale cohort of elderly individuals considered healthy and evaluated for a considerable follow-up, the average annual PSAV as well as the average fluctuation from the lowest to the highest PSA value are insignificant.
