[Leiomyosarcoma of the inferior vena cava. Presentation of 1 case of autopsy and review of the literature].

This is a clinico-pathological report of a 30 years old male patient that presented with acute epigastric pain. Ultrasound examination showed a retroperitoneal tumor, thrombosis of the inferior vena cava and ascites. CAT scan disclosed thrombosis of hepatic vein and inferior vena cava with right atrium involvement. Necropsy showed a leiomyosarcoma of the inferior vena cava. There are seldom reports of this tumor in the last 5 years and an early diagnosis allows therapeutic interventions associating surgery, radiotherapy and chemotherapy.

[Soft tissue sarcoma. Combined treatment of drug therapy, radiotherapy and conservative surgery].

The preliminary results of a prospective and cooperative protocol for the treatment of soft tissue sarcomas of trunk and extremities, stages IB-IIIB are presented. Thirty one patients (17 males, 22 with a tumor larger than 5 cm) aged 16 to 68 years, were treated with one dose of epirubicin 70 mg/m2 i.v. and radiotherapy (3000 rads in 10 fractions) Two or three weeks later an ample surgical complications occurred in 6 patients and were all of infectious origin. The median follow up period has been of 26 months. During this period 5 patients presented late surgical complications (edema in 4 and a pathological fracture in 1), 2 patients had a local tumor recurrence and distant metastases appeared in 7. Actuarial survival was 60% at 48 months. Ninety six percent of surviving patients conserved their extremity. It is concluded that with this treatment modality local recurrence is acceptable, morbidity is low and that the majority of patients do not require amputations or crippling resection.

Prospective study of amniocentesis performed between weeks 9 and 16 of gestation: its feasibility, risks, complications and use in early genetic prenatal diagnosis.

This paper demonstrates that the outcome of amniocenteses performed between the 9th and the 14th weeks is similar to that of amniocenteses performed between the 15th and 20th weeks. We have performed and prospectively followed 615 amniocenteses between the 9th and 16th weeks of gestation. The outcome, risks, and complications are similar to those of amniocenteses at the usual time (after 15 weeks) and to the other groups of early amniocentesis (before 15 weeks). Early amniocentesis differs from amniocentesis at the usual time in that it carries higher rates of fetal losses and of amniotic fluid leakage, more confined cytogenetic abnormalities, and an increased number of patients who have the procedure postponed. Two cultures (0.32%) failed to produce results, 595 (96.7%) samples were obtained at the first tapping, 20 (3.3%) at the second attempt. alpha-Fetoprotein levels reach their maximum at 13 weeks. Amniocenteses between 15 and 16 weeks (293, or 47%) constitute the control group, those between 9 and 14 weeks (322) the experimental group. Early amniocentesis appears to be a safe early genetic prenatal diagnosis technique, an alternative to chorionic villi sampling.

[Acute cardiac rupture in myocardial infarction. A case report].

A 60 year old woman with a large anterior wall myocardial infarction developed severe hypotension 12 hr after admission to the coronary care unit. X rays showed an enlarged cardiac shadow and echocardiography signs of pericardial effusion. Swan Ganz catheterization revealed severe venous hypertension and no suggestion of ventricular septal rupture. Emergency surgery, initiated with partial cardiopulmonary bypass, showed a 1 cm tear of the anterior wall of the left ventricle, close to the left anterior descending artery. A successful repair was obtained by suture on teflon pledgets. After a difficult postoperative course, the patient was doing well 8 months after surgery.

[Prolonged intergenesic period. A high risk factor?].

A prospective study is effected in 115 pregnant patients with an intergenesic period (IGP) of 7 years or more and it is compared with an equal number of patients with a minor IGP to this age. From these patients, 86 (74.8%) do not present pathology and 29 (25.2%) present it. These groups are divided in turn in two categories, from 35 years old to more and minors to this age. Differences are not found in the form of beginning parturition, way of this form of membranes breakage, duration of working of parturition and expellant between both independent groups to the maternal age. The perinatal results are alike except a minor average weight in mothers with prolonged IGP children. The patients with pathology were managed according to this, independent to their IGP. In conclusion only patients with prolonged IGP must be managed as high risk, when they present furthermore associated pathology and those patients with prolonged IGP independent to this duration have raised possibilities of success in vaginal parturition in absence of pathology.

[Anatomopathological behavior of gallbladder cancer. Frequency and importance of precancerous epithelial lesions of gallbladder cancer].

Surgical and autopsy materials were analyzed in a period of six years at La Paz, Bolivia "Bolivian Japanese Gastroenterological Institute" (Instituto de Gastroenterología Boliviano Japonés de La Paz, Bolivia), searching for macro and microscopic appearance of gallbladder cancer. Adenocarcinoma with infiltrative growth was the most frequent finding. Cholecystitis and Cholelithiasis were present in all the cases of gallbladder cancer. Epithelial lesions such hyperplasia, atypical hyperplasia and carcinoma in situ were frequent findings in the surrounding mucosa of invasive gallbladder carcinoma and not so frequent in benign gallbladder lesions. Group V of Nevin classification was common in our cases.
