RESUMO
We evaluated the biliopancreatic pathology by a non invasive method of Choloangiqgraphy by Magnetc Resonance (the first experience in Panamá). We correlated the method with the retrograde cholangiopancreatography, the surgical findings and the clinical evolution. Our conclusion is that the non invasive method allows us to have confidence in the findings for the biliopancreatic pathology.

A Western blot assay for identification of 26 kDa and/or 8 kDa antigens in a crude saline extract (CSE) of Taenia solium metacestodes, previously developed for human cysticercosis, was evaluated for use with pigs. The test population used for assay standardisation consisted of 45 cysticercotic pigs (5 pigs positive by necropsy and 40 selected by tongue palpation and LL-Gp immunoblot but not confirmed by necropsy), 48 pigs with heterologous infections and 40 negative controls from endemic and non-endemic areas. The test detected 93% of the cysticercotic group and was 100% specific. In a field study this antigen preparation was compared by immunoblot with antibody recognition for Gp13-50 antigens in a lentil-lectin semi-purified glycoprotein extract of T. solium (LL-Gp). The seroprevalence to CSE antigen was slightly lower (26/75) when compared to LL-Gp (29/75) and this represented a non-significant difference. The CSE Western blot assay was used to assess seroprevalence of T. solium cysticercosis in pig populations in the state of Yucatan, Mexico. A total of 1099 pigs sampled at random from 25 villages revealed a seroprevalence of 23% (253/1099). Seroprevalence in intensively reared, farmed pigs was 2% (7/228). In comparison with farmed pigs, the seroprevalence was 33% (172/513) in free-roaming backyard pigs (OR=13.86, CI=4.0747.22, p<10(-6)) and 25% (74/98) in semi-confined backyard pigs (OR=14.03, CI=5.60-35.16, p<10(-6)). There was no significant difference in seroprevalence by sex (p=0.23). Seroprevalence decreased with age (chi(2)-test for linear trend=7.803, p<0.006). Results of this study demonstrate that the CSE Western blot can be applied for reliable immunodiagnosis of T. solium cysticercosis in pigs. Furthermore, variation in pig husbandry in Yucatan indicated significantly higher exposure to cysticercosis in free-roaming backyard pigs compared to intensively reared animals from the same area.

The authors review the penile ultrasound records of 47 patients referred from the Urology Service with a diagnosis of Erectile Dysfunction. The pear systolic and and diastolic pressures were measured every 5 minutes for 30 minutes after the intracavernous injection of 60 mg of Papaverine, as well as the diameter of the cavernous arteries before and after the injection which was made using a 25 gauge needle. A tourniquet was applied at the base of the penis while injecting and was kept in place for 2 minutes after the injection was completed. The results were normal in 16 (34.04%) and abnormal in 31 (65.95%) patients. Of these, 27 (87.1%) had an abnormal vascular response and in 4 (12.9%) it was of an undetermined type. The abnormal vascular response was due to arterial insufficiency in 12 (44%) and to venous insufficiency in 15 (56%). The authors also found that the diameter of the cavernous arteries increased 15% to 120% (-/+ = 68%) in the patients with normal studies, 17% to 100% (-/+ = 58.1%) in those with arterial insufficiency and 23% to 89% (-/+ = 52.3%) in those with signs of venous insufficiency

The clinical records of 18 children were studied, between 15 and 60 days old. They were hospitalized due to vomiting and diagnosis of suspected pyloric hypertrophic stenosis (PHS). The sonography confirmed the diagnosis in 8 children, by the thickening of the muscular layer and enlargement of the pyloric canal. The surgery (pyloromyotomy) ratified the diagnosis in all 8 children. They all were in good health after being operated.
