[Value of cavernous gasometry in the physiopathologic diagnosis and treatment of priapism].

Currently, each case of priapism therapy must be customized depending on the patient's individual pathophysiology. To this end, in addition to anamnesis and the macroscopic aspect of the suctioned blood, quantification of existing ischaemia by cavernous gasometry is quite important. This will make possible the distinction between two types of priapism: ischaemic, vein-occlusive or low-flow; and nonischaemic, arterial or high-flow. Each of these priapism types presents a clearly different mechanism of production and, more importantly, a different response to the various therapeutic options currently available. The ischaemic form responds to suction-washing procedures and to the various techniques of vein by-pass. On the contrary, these manoeuvres will be useless in non-ischaemic or arterial priapism, where alpha-adrenergic injections or lacerated artery embolization should to be used.

[Carcinoid tumor of the cecal appendix].

In connection with carcinoid tumor of the appendix as an incidental finding in appendectomies, we carried out revision in a period of 5 years, from 1983 through 1987, in the General Hospital of Venezuelan Institute of Social Security in San Felix, Bolivar State. We found two cases of carcinoid tumor of the appendix in 1433 appendixes that were examined by the Service of Pathology. Both cases were males patients who were admitted due to acute appendicitis. They represented 0.14% of the total appendectomies. We review on the subject and we find that the frequency is like to that published up to now. We agree with others authors in that simple appendectomy in the carcinoid tumor of the appendix is curative in tumors < 2 cm.

[Incidental carcinoma of the kidney with renal vein thrombosis].

Incidental carcinoma of kidney is an increasingly common pathology as a result of a wider use of high resolution diagnostic methods. The special characteristics of these tumors, usually small and in a low grade or stage, make conservative surgery to be considered as a valid therapeutical option. An incidental carcinoma of kidney with tumoral thrombosis of the renal vein undetected in the pre-surgical study, circumstance which allows to emphasize the malignant potential of these tumors is presented here. Based on this, we believe that a meticulous evaluation of the renal vein condition should be made, in patients considered as possible candidates for conservative surgery. In this sense, selective renal phebography and magnetic resonance could be considered explorative means that play an important role in the introduction of renal preservation surgery, if future studies show that its use allows an early detection of the tumoral condition of renal vein.

Cryptosporidiosis in chickens from southern Spain.

Cryptosporidiosis in chickens from southern Spain is reported. Cryptosporidia were found in the trachea, esophagus, and epithelium of the bursa of Fabricius in chickens from different regions. In one flock, cryptosporidiosis was associated with respiratory problems and high mortality. In another flock, it was associated with low mortality and weight loss.

[Early stimulation: 10 years' experience].

Infancy psychomotor yield in lower socioeconomic levels can be damaged from the first year of life. This implies future consequences to individuals, family-and society. Early stimulation programs have demonstrated to improve psychomotor yield in the above mentioned children. In Temuco, Chile, in groups of children with different risks, that were incorporated to an early stimulation program, it has been seen that the lower the birth weight the greater the risk of future psychomotor deterioration, which is also true for children that survived neonatal meningitis. On the other hand, in children that presented hyperbilirubinemia, low Apgar scores and neonatal septicemia, no significant statistical differences in psychomotor development have been observed in comparison with those of similar birthweight but without these antecedents. In this study the Chilean Health Ministry's Evaluation and Psychomotor Stimulation Program is reviewed as to adapt it for children at greatest risk.

[Transient idiopathic periosteal hyperostosis with hyperproteinemia (Goldbloom syndrome)].

The case of a 13 year old girl is presented, who developed intense pain in extremities and experienced marked weight loss after an acute upper respiratory tract infection. Roentgenograms revealed a diffuse periosteal reaction, most intensely affecting long bones. Principal laboratory findings were a slight normocytic, normochromic anemia; high erythrocyte sedimentation rate; medullar plasmocytosis and dysproteinemia, with a large increase in plasma gammaglobulin concentration. Clinical recovery and normalization of roentgenograms and laboratory parameters were observed eleven months after the acute episode, with no intervening therapeutic measures. This case matches Goldbloom's syndrome, described originally in two children in 1966. Only 3 other cases have been reported in the literature.
