Human chorionic gonadotropin in esophageal carcinomas. An immunohistochemical study.

We have examined immunohistochemically the presence of human chorionic gonadotrophin (hCG) in 29 esophageal carcinomas: 24 squamous cell carcinomas, 2 adenocarcinomas, 2 adenoid cystic carcinomas and 1 adenosquamous carcinoma. In hCG-positive tumors, the presence of human placental lactogen (hPL) and pregnancy-specific beta-1 glycoprotein (SP-1) was also assessed. HCG immunoreactive cells were found in 5 squamous cell carcinomas (21%) and in none of 5 non-squamous cell tumors.

Mediastinoscopy as an emergency diagnostic procedure in superior vena cava syndrome.

Seven men and one woman (aged 20-70 years) with superior vena cava syndrome underwent diagnostic mediastinoscopy to elucidate the cause, which other, lesser procedures had not identified. Intraoperative frozen-section studies of the biopsy specimens revealed small-cell carcinoma (4 cases), large-cell carcinoma (1), squamous-cell carcinoma (1), large-cell lymphoma (1) and Hodgkin's lymphoma (1). Radiotherapy or chemotherapy was initiated within the following 24 hours in six cases.

[Enterovesical fistula caused by a prosthesis made of synthetic material].

Enterovesical fistulas affect mainly male patients, due to the interposition of the uterus in women. They can be caused by neoplastic, inflammatory or traumatic processes. A case of ilovesical fistula due to migration of a silastic plate used to repair an epigastric infissional hernia is presented.

[Entero-urinary fistula. A study of 22 cases].

We performed a retrospective study on 22 patients with entero-urinary fistulas that had been diagnosed and treated at the Hospital Clinico i Provincial in Barcelona during the period spanning 1981-1988. Fistulas were classified according to the organs or parts with which they communicated. Among the important etiogenic conditions were diverticular disease of colon.

[Prognostic factors of neurosensory sequelae in extremely premature infants].

Modern neonatal intensive care has led to a rise in the survival rate of very low birthweight infants (VLBW), but at the same time is a greater number of neurosensorial sequelae. In this study, 50 VLBW (weight less than 1,500 g) babies followed up for at least 12 months are analysed. 18% showed major sequelae (40% of those weighing less than 1,000 g, 12.

[Ascending thoracic aorta-supraceliac abdominal aorta by-pass in a patient with coarctation and partial hypoplasia of the arch and aortic isthmus].

A twenty years old patient, with arterial hypertension at the right arm and absent pulse in both lower extremities was studied by angiography, and a coarctation of aortic arch with partial hypoplasia of aortic arch and aortic isthmus was found. Patient underwent to a surgical operation and, by anterior approach, an ascending thoracic aorta-supraceliac abdominal aorta by-pass was made. In the present case report, advantages, indications and experience with such by-pass modality are review.

[Anterior rhinomanometry].

Assessment of the anterior rhinomanometry on 9 normal persons with the aim to know the variations between several individuals and in each one. The examination, performed on 3 consecutive days, showed a great interindividual variability and an acceptable individual variability. Accordingly the AA.

[Pyonephrosis as a cause of acute peritonitis. Review of the literature and report of a case].

We report on a 52-year-old patient with spontaneous intraperitoneal rupture of pyonephrosis. The diagnostic features, preoperative findings and treatment are discussed and the literature reviewed.

Does low-dose aspirin prevent aortocoronary vein bypass graft occlusion? The Spanish Group for Aortocoronary Bypass Follow-up (GESIC Study).

Although the importance of antiplatelet treatment in preventing early bypass occlusion has been clearly recognized, questions regarding the optimal drug regimen remain. To study the efficacy of low-dose aspirin, alone or in combination with dipyridamole, 927 consecutive patients were enrolled in a multicenter, randomized, double-blind, placebo-controlled trial comparing aspirin, 50 mg t.i.

[Urinary tract infection in the newborn infant].

Twenty-eight cases of urinary tract infection in newborns with positive urinoculture and suggestive clinical symptomatology are reviewed. The incidence was 0.24%, being most frequent in preterm and postterm newborns.

Placental proteins in high-grade urothelial neoplasms. An immunohistochemical study of human chorionic gonadotropin, human placental lactogen, and pregnancy-specific beta-1-glycoprotein.

We examined the presence of human chorionic gonadotropin (HCG) in 16 low-grade and 47 high-grade urothelial neoplasms, including two cases with trophoblastic-like differentiation. In HCG-positive tumors, the presence of human placental lactogen (HPL) and pregnancy-specific beta-1-glycoprotein (SP-1) also was assessed. HCG immunoreactive cells were found in nine of the 47 high-grade tumors (19%), whereas none of the low-grade tumors were positive for HCG.

[Laparoschisis. Apropos of 6 cases].

We report on 6 laparoschisis treated in the last 5 years. Five patients survived whereas one died at the age of 41 days. We review clinical aspects of this malformation and point out the need for a prompt operation and an adequate nutritional management.

[Primary nodular amyloidosis of the tongue].

Two cases of nodular primary amyloidosis of the tongue are reported. A review of the literature is made.

[Aberrant renal papilla. Description of a new sign and review of the literature].

The aberrant renal papilla or papillary invagination is an uncommon congenital anomaly which, because of its radiological appearance, should be included in the differential diagnosis of processes associated with filling defects in the renal pelvis. Its halo of radiolucency and its longitudinal striae, its solid echogenicity and a possible associated vascular anomaly (angiodysplasia) should constitute the basis of the diagnosis. An ultrasonographic evaluation, conducted every 6 to 12 months can constitute, as in the case presented here, a form of follow-up avoiding the need for radical therapy.
