RESUMO
El cáncer de cuello uterino es la neoplasia más frecuente del tracto genital femenino, que en su forma avanzada puede invadir localmente a tejido paracervical, vagina, vejiga y recto. Se presenta un caso, muy poco frecuente, de carcinoma cervical con extensión endometrial como neoplasia in situ, en una paciente de 76 años y que se manifestó clínicamente como piometra.
Cervical cancer is the most common malignant tumor of the female genital tract, which in its advanced stage can invade locally paracervical tissue, vagina, bladder and rectum. A case extremely rarely is reported of cervical carcinoma with in situ carcinoma involving to endometrium in a patient of 76 years old and clinically manifested as pyometra.

Castleman's disease is an uncommon lymphoproliferative disorder which can be unicentric or multicentric. Hialine vascular variant is the most common pathologic form, which is usually unicentric and presenting as mediastinal tumors. We report a 31-year-old female with a history of retrosternal pain. A chest CAT sean showed a tumor in the posterior mediastinum. The patient was operated and the tumor excised. The pathology report showed a Castleman's disease. No other tumors were found in the patient, who had a favorable evolution.

Se presenta el caso de un paciente operado por tumor testicular izquierdo, cuyo estudio anatomopatológico concluyó una fusión esplenogonadal. Se entrega información respecto a esta rara malformación y se mencionan herramientas diagnósticas que pueden ayudar al diagnóstico preoperatorio con la consiguiente reducción de la cirugía radical testicular.

The incidence of enterotoxigenic Escherichia coli (ETEC) has been studied in 85 children with acute diarrhea in patients in the Hospital de Niños Pedro de Elizalde, Buenos Aires, and in 38 healthy children. All of them were up to four years old and none had received antibiotic treatment within 7 days before sampling. ETEC was recovered in 9 out of 85 (10.6%) children with diarrhea. From these positive cases, 6 were associated with heat-stable (ST), 1 with heat-labile (LT) and 2 with both LT and ST enterotoxins. Only one case (2.6%) of LT-producing ETEC was detected in the control group. In 5 out of 9 ETEC diarrhea cases (55.5%) the isolated strains expressed human colonization factor antigens (CFA); four of them were CFA/I and one CFA/II. The characteristics of the CFA, biotype, serotype and antibiotic sensitivity pattern were studied in 23 E. coli isolates from 10 ETEC positive children. Of the 12 ST only strains, 5 (41.7%) expressed CFA/I and 2 (16.7%) CFA/II (CS2 + CS3). One out of 2 LT/ST strains expressed CFA/I. CFAs were not detected in the ETEC-LT nor in the toxin negative E. coli strains. From the ETEC isolated, 82.4% were resistant to 4 or more antibiotics, whereas only 50% of simultaneously isolated toxin-negative E. coli presented this sensitivity pattern. The different ETEC strains belonged to several different serotypes, some of them rarely observed in other countries. None of these serotypes correlated either with the toxin profile or with the sugar fermentation pattern.(ABSTRACT TRUNCATED AT 250 WORDS)
