[Human blastocystosis: prospective study symptomatology and associated epidemiological factors].

An attempt has been made to contribute to the understanding of the symptoms and factors associated with the Blastocystis Hominis infection, as seen in persons seeking outside consultation from the Dermatological and Transmissible Diseases Department (DTDD) at the C.H.N.H. This is a case-control study carried out in people between the ages of 5 and 80 in a period from January to March 1999. The cases tested positive in parasitological tests for Blastocystis Hominis and were absent of other enteropathogens. The controls tested negative in parasitological tests for Blastocystis Hominis and were absent of other enteropatoghens. A clinical chart was used to register details of symptomatology and factors associated with the Blastocystis Hominis infection. 74 cases and 70 controls were studied, matched by sex and age. A statistical correlation was obtained (p<0.05) among symptomatic persons and presence of Blastocystis Hominis (91,9%). The symptomatology associated with the Blastocystis Hominis infection by order of statistical significance (p<0.05) was: Abdominal pain (OR=3) 1.47<OR<6.60, abdominal ballooning (OR=2.36) 1.06<OR<5.29, urticaria (OR=3.19) 0.81<OR<12.48. The only risk factor associated with the Blastocystis Hominis infection was the consumption of unboiled water (OR=2.52) 1.01<OR<5.83. In conclusion, Blastocystis Hominis is associated to symptomatic subjects with abdominal pain and ballooning and urticaria, who possess at least two or three positive tests. This infection would be facilitated by the consumption of unboiled water.

[Balloon valvuloplasty in stenotic bioprosthesis].

The results of balloon valvuloplasty performed on five patients with stenotic bioprosthesis treated in the Hospital de Cardiología Centro Médico Nacional Siglo XXI, are presented. All five bioprosthesis were right sided, two in tricuspid position, one in pulmonary valve position and two in valvulated conduits from right ventricle to pulmonary artery. In all cases a pressure gradient reduction was achieved, an improvement of clinical functional class and heart failure manifestations were obtained. Mansfields balloons were used. One in two patients, and two balloons in three. We had not complications with the procedure. We conclude that balloon valvuloplasty on bioprosthesis is a safe and dependable procedure to be used in right sided bioprosthesis.

[Doppler echocardiography in endomyocardial fibrosis].

Twelve patients with endomyocardial fibrosis with angiographic and/or histologic corroboration were studied with Doppler echocardiography with the purpose of describing the echocardiographic features and identify the affected sites. The average age was 41 years (range 16 to 59 years), 2 men and 10 women. Three patients (25%) had isolated right ventricular involvement, one patient (8%) left ventricular, 8 patients (66%) both ventricular. Our Doppler echocardiographic findings were: right atrium enlargement (91%), right ventricle outflow dilatation (83%), paradoxical septal motion (83%), left atrial enlargement (33%), mitral and tricuspid valve prolapse (50%), pericardial effusion (41%), mitral regurgitation (75%), tricuspid regurgitation (100%), apex obliteration (50%) and a restrictive type flow pattern (50%). Doppler echocardiography is a useful method for the diagnosis of endomyocardial fibrosis, the finding of normal or small ventricles associated with apex obliteration and enlarged atria, mitral or tricuspid regurgitation and a restrictive type flow pattern are characteristics of this disease. In our population, the isolated or predominantely right ventricular involvement is the most common finding as it represented 83% of the cases.

[The prevalence of giardiasis in patients who undergo gastroduodenoscopy].

Giardiasis constitutes a very frequent intestinal parasitic infection in our country, with a varied digestive symptomatology. We performed a prospective, transversal study, with the aim to establish the frequency of G. lamblia in digestive symptomatic patients submitted to upper gastrointestinal endoscopy examination trying to relate its isolation with the endoscopic findings. We studied 50 patients; they were submitted to upper endoscopy examination. During the procedure, we aspirated duodenal content and six duodenal biopsies were taken; 8 to 14 hours before endoscopy, they swallowed the Enterotest encapsulated string. The presence of G. lamblia was established by three methods (Enterotest, duodenal content, impront). The day, of the endoscopic examination they resolved a questionnaire of digestive symptoms they had during the last 4 weeks. The endoscopy was informed like normal in 15 patients. (30%). Duodenitis was detected by endoscopy in 9 patients (18%), but neither one of them demonstrated presence of G. lamblia. By the three diagnostic methods, the presence of G. lamblia was demonstrated in 5 patients (19%), without endoscopic duodenitis, being the digestive symptom scores not statistically significant respect to symptomatic patients without G. lamblia. We concluded that the three diagnostic methods used to identify G. lamblia were equally sensitive. No preponderance of digestive symptoms were present in patients with G. lamblia in relation to in our country patients without G. lamblia infection. We recommend to consider duodenal aspiration during endoscopy in order to discard giardiasis.

[Atherosclerotic ischemic cardiopathy in patients with dextrocardia in situs viscerum inversus].

We describe the incidence, clinical, radiologic, electrocardiographic, echocardiographic and angiographic findings of two cases with dextrocardia in situ viscerum inversus with ischaemic heart disease. The first patient had coronary artery saphenous bypass graft and is currently asymptomatic with a negative maximal stress test. The other patient with diabetes mellitus and unfavorable coronary anatomy was not operated and is currently with stable angina on class II of the NYHA. The electrocardiographic, echocardiographic and angiographic strategies are commented.
