Seeding from hepatocellular carcinoma after percutaneous ablation: color Doppler ultrasound findings.

Background: We describe the clinical and color Doppler ultrasound findings in a series of cases of seeding from hepatocellular carcinoma (HCC) observed in patients treated with percutaneous ablation therapy (PAT) over a 15-year period.

Methods: We reviewed the clinical and imaging records of 12 patients with cirrhosis (nine men and three women, age range 51-82 years, mean age 63 years) that showed neoplastic seeding from HCC occurring after one or more PAT procedures. Five of 12 cases of seeding were observed as a complication of 1080 PAT procedures (0.

Fatal immunodeficiency in a patient with thymoma and Good's syndrome.

Thymoma is a rare tumor characterized by an association with autoimmune diseases. Immunological abnormalities are increasingly being recognized in thymoma patients and are the cause of a peculiar susceptibility to infections. The authors present the clinical history of a thymoma patient affected by fatal immunodeficiency.

Mediastinal images resembling thymus following 131-I treatment for thyroid cancer.

The follow-up of Differentiated Thyroid Cancer conventionally includes serum thyroglobulin and periodic Whole Body Scans. The uptake of 131-I in normal and pathological tissues different from metastatic thyroid cancer sites is a cause of false-positive scans. Among them, mediastinal uptake caused by thymic hyperplasia can be observed.

Phase II study of temozolomide plus pegylated liposomal doxorubicin in the treatment of brain metastases from solid tumours.

Objective: A combination regimen of temozolomide (TMZ) and pegylated liposomal doxorubicin has been evaluated in the treatment of brain metastases from solid tumours.

Study Design: Nineteen consecutive patients (pts) have been enrolled in a prospective phase II trial and treated with TMZ 200 mg/m2 (days 1-5) and pegylated liposomal doxorubicin 35 mg/m2 (day 1) every 28 days. The study was prospectively projected according to the Simon's two-stage optimal design.

Tumoral calcinosis: a case report.

Tumoral calcinosis is a rare tumour-like mass characterized by soft tissue calcification of obscure aetiology. A case of tumoral calcinosis is presented here, and its clinical, radiological and pathological features are described. The differential diagnosis versus hydatid cyst is discussed.

Molecular technology and the recombinant TSH have changed diagnostics of thyroid carcinoma with positive I-131 whole body scan but low serum thyroglobulin.

The early detection of recurrent differentiated thyroid carcinoma (DTC) cells in the post surgery DTC patients relies on the sensitivity of measuring both the level of thyroglobulin (Tg) and 131-Iodine distribution by Whole Body Scan (WBS). Undetectable level of Tg associated with negative WBS or elevated levels of Tg associated with positive WBS ("concordant") is ordinarily indicative of either absence or presence of disease. At times, elevated level of Tg with negative WBS or low levels of Tg with positive WBS ("discordant") could also occur.

Oxaliplatin/rituximab combination in the treatment of intermediate-low grade non-Hodgkin's lymphoma of elderly patients.

High and intermediate grade non-Hodgkin's lymphomas (NHL) require treatments with aggressive chemotherapy schedules. However, low grade NHLs display a low chemoresponsiveness and patients aged >65 years often do not tolerate anthracycline and corticosteroid-containing chemotherapy regimens. Therapeutic options in this subset of patients are watchful waiting, oral alkylating agents, purine nucleoside analogues, combination chemotherapy, interferon and monoclonal antibodies.

Brain anatomy and development in autism: review of structural MRI studies.

Autism is a neurodevelopmental disorder that severely disrupts social and cognitive functions. MRI is the method of choice for in vivo and non-invasively investigating human brain morphology in children and adolescents. The authors reviewed structural MRI studies that investigated structural brain anatomy and development in autistic patients.

The influence of diabetes mellitus on primary open angle glaucoma perimetry.

We have carried out a study into retinal sensitivity alterations in the course of primary open angle glaucoma to see if their appearance and evolution might be influenced by concomitant diabetes mellitus. The visual field examination (Perimeter Octopus 500 EZ, programme G1) indicated prevalent sensitivity defects in the superior hemifield, both in glaucoma only subjects and in those with diabetes as well. As to the inferior hemifield, a greater, statistically significant, retinal sensitivity defect was found in the inferior temporal quadrant of the left eye in the group of diabetics.

Renal involvement in IgD myeloma.

Nine patients affected from IgD myeloma were studied retrospectively in order to elucidate the incidence and peculiar traits of related nephropathy. Eight patients developed chronic renal failure, and as many as 5 were already suffering from renal failure since first admission to the hospital. In 3 cases acute renal failure was the major presenting symptom of the disease.
