IgG4-related disease (IgG4RD) is a recent inflammatory process of supposed autoimmune etiology, which is characterized by elevated serum IgG4 levels, dense lymphoplasmacytic infiltration rich in IgG4-positive plasma cells and storiform fibrosis. Tubulointerstitial nephritis is the most common renal manifestation, with different degrees of kidney dysfunction and variable clinical findings. Herein, the authors describe a new case of IgG4 tubulointerstitial nephritis (IgG4TN), and discuss clinic and pathologic criteria...

OBJECTIVE: To evaluate the association between quantitative ultrasonography at hand phalanges (QUS) and dual energy X-ray absorptiometry (DXA), and between these methods with food intake and history of bone fractures. SUBJECTS AND METHODS: After two years of follow up of 270 schoolchildren, 10 of them, who showed bone mass below - 2 SD in QUS, were included in the present study. Laboratory results and DXA data were analyzed. RESULTS: Bone mass evaluated by DXA at L1-L4 ranged from -2...

To determine whether hyperalphalipoproteinemia modifies carotid intima-media thickness (cIMT) and/or influences the relationship of clinical and biochemical parameters with cIMT. This study was conducted on 169 asymptomatic individuals, classified as hyperalphalipoproteinemic (Hyper-A) (Hyper-A, n = 71, HDL-C > or =68 mg/dL) and controls (CTL) (CTL, n = 98, HDL-C >32 and <68 mg/dL). Enzymatic, nephelometric and ultracentrifugation methods were used for biochemical determinations. Hepatic lipase (HL), lipoprotein lipase (LPL), cholesteryl ester transfer protein (CETP) and phospholipids transfer protein (PLTP) activities were measured by radiometric exogenous methods...

AIM: To determine the impact of prognostic factors on survival of patients with metastases from colorectal cancer that underwent liver resection. METHODS: The records of 28 patients that underwent liver resection for metastases from colorectal cancer between April 1992 and September 2001 were retrospectively analyzed. Thirty-eight resections were performed (more than one resection in eight patients and two patients underwent re-resections). The primary tumor was resected in all the patients...

Hemangiomas are the most common benign vascular tumor found in the liver. In this study, 103 cases of hepatic hemangiomas were analysed in a retrospective manner. Image aspects such as those seen in ultrassonography, computed tomography, nuclear magnetic resonance and arteriography are discussed. The incidence was higher amongst the female sex, between individuals from 40 to 60 years old, which presented predominantly without symptoms (66%) and localized mainly in the right hepatic lobe (74%). The meaning of those aspects, when adopted, permits the clinicians to differentiate benign from malignant nodular lesions in the liver...

Hepatocellular carcinoma (HCC), one of the most frequent tumors in the world, is included by the World Health Organization as a relevant public health problem in areas of high incidence as Africa and Southeast of Asia. In this review it will be discussed: a) the close relationship between HCC and hepatitis B virus (HBV), the more universal but not the single etiologic factor having other carcinogens and co-carcinogens involved with the origen of the tumor; b) the great variation in geographic distribution of this tumor, including that of Brazil where the incidence of HCC, including the new macroscopic classification according to the pattern of growth and general with liver cirrhosis in all countries where the tumor is diagnosed; d) some morphological aspects of HCC, including the new macroscopic classification according to the pattern of growth and general characteristics of small HCC; e) the clinical and biochemical aspects, calling attention to the evaluation of serum levels of alpha-fetoprotein, not always increased in patients with HCC, and the immage processing methods, specially ultrassonography, as methods for early diagnosis of HCC, being relevant in the follow-up of high risk patients (cirrhotics HBsAg (+]...
