[New contributions to the study of chromophobe-cell renal carcinoma].

Objective: The present study describes a case of the recently discovered chromophobe cell carcinoma of the kidney. Additional findings that have not been previously reported are presented and the importance of the clinical and anatomopathological diagnosis of this tumor type is underscored.

Methods: The tumor presented in a 72-year-old female with symptoms and signs that were not distinct from those of other more common renal tumors.

Breast cancer detection with sestamibi-Tc-99m and Tl-201 radionuclides in patients with non conclusive mammography.

Early diagnosis of breast cancer using breast examination, mammography and ultrasonography is highly accurate, but radiologically dense breast represent a challenge for the mammographic detection of early stage tumors. The aim of this study is to determine the clinical value of scintigraphic techniques in the early diagnosis of breast cancer when other methods give non-conclusive results. The study includes 160 women with clinical suspicion of breast cancer and non-conclusive findings in mammography, randomized either to scintigraphic scans with Sestamibi Tc 99m or Tl 201.

[Amplification: somatosensory or cognitive?].

Somatosensory amplification refers to the tendency to experience somatic and visceral sensations as intense, noxious and disturbing and has been related to a variety of psychiatric disorders and more specifically to hypochondriasis. A Spanish version of the Somatosensory Amplification Scale was applied to a sample of 60 outpatients divided into three groups: hypochondriacs, non-hypochondriac somatizers and non-somatizers. The scale showed a good internal consistency (alpha = 0.

Drug fever attributable to Calcium Dobesilate.

Many drugs may cause fever through different mechanisms, the most frequent being hypersensitivity. We are reporting on two cases of drug fever attributable to Calcium Dobesilate, a drug used for treating chronic venous insufficiency and other vascular disturbances. The diagnosis was made by oral challenge with the drug.

[Parkinsonism induced by sodium valproate].

Parkinsonism is a rare side effect of treatment with sodium valproate. We report 2 elderly women who developed parkinsonian syndrome several years after starting valproate therapy, and in whom symptoms disappeared when treatment was withdrawn. These cases, along with others in the literature, may support experimental evidence for the importance of GABAergic modulation in motor control.

[Primary epidermoid carcinoma of the bladder. Its diagnosis and treatment and a review of the literature].

Presentation of four patients with primary plain epidermoid carcinoma of the bladder. The patients, three men and one woman, aged 50-74 years, presented clinically with gross haematuria and irritative mictional syndrome; their background was prostatism with in-dwelling vesical catheter and repeat urinary infections. Revision of the immunohistochemical pattern and the clinico-pathological differential diagnosis, as well as the pathoetiology, biological behaviour and management of this uncommon type of tumour.

[Heart arrest in outpatients resuscitated without neurologic sequelae].

Background: Around 65% of the deaths by acute myocardial infarction are presented in the first hour of the attack when most patients are outside a hospital and it is almost always caused by ventricular fibrillation. Home defibrillation permits these patients to be saved if an integral emergency system is available.

Methods: The cases of ambulatory cardiac arrest resuscitated with no residual neurologic lesions in the province of Ciudad Real were reviewed.
