Presentation of a new case of synchronic concurrence of renal adenocarcinoma and papillar carcinoma of renal pelvis on the same kidney. The origin of this double malignant renal tumour remains unknown, although several hypothesis have been raised. We believe that coexistence of both tumours is more than casual and we would underscore the morphogenetic interpretation of such coincidence.
Data was obtained from 4189 volunteer blood donation records in two hospital-based blood banks in Puerto Rico to determine whether Hispanics have higher serum alanine aminotransferase (ALT-SGPT) activity than donors from other racial-ethnic groups. The overall mean value of ALT-SGPT in the study population was 36.84 u/l (range 1-910, standard deviation 37.8). When the logarithm of ALT-SGPT (log ALT) was calculated for all subjects, the overall, mean for log ALT was 1.47 (range 1-2.96, standard deviation 0.27). Analysis of each blood bank's donation records at two different time periods showed a consistently high ALT-SGPT activity even when donations positive for hepatitis B surface antigen or other serologic markers were excluded. Though the causal factor of this finding is not clear, non-infectious environmental such as alcohol consumption should be considered as a probable explanation.
We describe a case of recurrent urinary tract infection in a male patient that had been repeatedly associated with sporadic sexual intercourse with his partner. The timing of the episodes and the bacteriological findings indicate this to be another uncommon case of urinary tract infection sexually transmitted by the female to the male.
Hypothyroidism is one of the most frequent causes of treatable symptomatic dementia. However a detailed description of its neuropsychologic characteristics in the medical literature is lacking. We have studied a 70 year old patient suffering severe mental deterioration, cerebellopathy, myopathy and hypothyroidism with a complete set of neuropsychologic and psychometric tests: mental mini-examination, Blessed's scale, neuropsychologic examination, WAIS, Bento visual retention test, Rey's picture, words learning, delayed recall of words, verbal fluency, reaction times and maintained attention. This type of dementia is characterized by a low score in all tests which improves progressively with the treatment and it is also accompanied by a lack of language defects, nonconstructive apraxia or agnosia. The recovery involves the attentional field and the memory as well as the two intelligence indices. However this improvement is more apparent in the tests related to attention and visuospatial information processing. It is concluded that hypothyroid dementia in this patient had characteristics "subcortical dementia" and a neuropsychologic deterioration pattern rather nonspecific with a slight predominance of the attentional and visuospatial defects.

We present two cases of angioma of the glans penis and we reviewed this disease entity from a clinical and therapeutic points of view, classically understood as a proliferative process of a malformative nature. However, both cases that are described can be interpreted as true vascular tumors of a benign nature.
