[Total parenteral nutrition. A 1-year experience with 96 patients].

In 1987, ninety-six surgical patients, of whom 44 were premature or newborn babies and 52 were infants or older children, received total parenteral nutrition (T.P.N.) at our hospital. A peripheral venous line was utilized on forty patients in the first group and only on 9 in the second group. The excellent results yielded by T.P.N. are self-evident from the low mortality showed by these patients. Thirty-three out of the 44 neonates and premature infants with serious surgical problems survived, being noteworthy the occurrence of just 3 deaths within a series of 13 necrotizing enterocolitis. In the series of 52 infants and older children, composed of 13 digestive patients (with 5 liver transplants), 6 tumoral, 9 neurologic, 4 renal (2 transplantations), 18 cardiac, 1 thoracic and 1 burnt, only 9 patients died. The average duration of T.P.N. was 10 days in the group of premature and newborn infants and 6 days for the nursing infants and older children, save for the 8 patients in whom the treatment had to be prolonged for a few months. We conclude that T.P.N., when applied in time and of short duration should entail no risk at all. In neonate and premature infant a peripheral vein shall be the route of choice. In the nursing infant and older child a central venous line is preferable, if possible the superior vena cava or its major tributary veins.

[The use of clomiphene and menotropins as inducers of multiple follicular growth in a program of in vitro fertilization].

In our IVF & related techniques program, clomiphene 50 mg was used from days 2 to 6 of the cycle in 20 patients and 20 cycles. (17 IVF patients and 3 GIFT patients) menotropins were also used in 2 different schemes: a) 2 ampules in alternated days (12 cases) and b) one ampule daily (8 cases). The patients with the daily scheme required lesser total dose of menotropins and developed higher estradiol levels, although this had none statistic significance, and they also developed a greater number of follicles. There were 16 laparoscopies for ovum capture and 53 oocytes were retrieved (30.2% mature) 10 oocytes were from the GIFT patients. 16 oocytes were fertilized and 8 cleaved. There was only one pregnancy from and IVF patient with the alternated scheme that ended with a first trimester abortion.

[Bolande's tumor: significance of its early diagnosis and treatment].

Four patients diagnosed of having a tumor of Bolande and treated at our institution in the past ten years are presented. In two of them, early diagnosis was aided by prenatal echographic techniques; the other two diagnoses were suspected ar three and ten days of age because of an abdominal mass. The four of them underwent a complete study which included: a plain abdominal film, an ultrasound scan and an intravenous urogram; the last three patients were also surveyed by a CT scan of the abdomen. Surgery was undertaken early on all the patients, the time of operation being in every instance within the first month of life. A laparotomy was performed and, once the contralateral kidney had been carefully examined, a nephroureterectomy was implemented, having been able to preserve in all the cases the suprarenal gland in view of the benign nature of the tumor. A histologic study confirmed the diagnosis and revealed the complete delimitation of the tumor by the renal capsule. The authors underscore the importance of this tumor's suspicion in the face of any solid renal mass detected by prenatal echography or in the neonatal period, since early diagnosis and treatment are imperative in order to prevent the ensuing complications in the rare and unfortunate cases that show a malignant tumoral trend.

[Hepatic lesions caused by alpha 1-antitrypsin deficiency in childhood. Review of 14 cases].

Fourteen cases of alpha-1-antitrypsin deficiency are presented. All of them had a PIZZ phenotype except two in which a PIMZ phenotype was found. It must be pointed out that histological findings show a great variability among the different patients most of which did not have intracellular PAS-positive amylase inclusions in liver biopsy specimens. Clinical course did not correlate with either the age of onset of the disease or the phenotype found, thus indicating that other additional factors are involved in determining prognosis. We insist on the importance of a careful study of all neonatal hepatitis syndromes in order to rule out a alpha-1-antitrypsin deficiency.

[Mediastinal teratomas. A clinical and pathologic study of 3 pediatric cases].

Mediastinal teratomas are reported in three children. Two cases: an eighteen-month-old female and a twelve-years-old female, were diagnosed of mature cystic teratoma. Third patient was a twelve-year-old male with an immature mediastinal teratoma. All tumors were located in anterior mediastinum. Mediastinal mature cystic teratomas were completely excised and their evolution were favourable. However, immature mediastinal teratoma infiltrated lung parenchyma and great blood vessels; in this case only a biopsy was performed. This patient died a month after surgical procedure. Clinical, radiological and pathological findings of mediastinal teratomas in childhood are commented. Prognostic factors and evolution of different histological types of mediastinal teratomas are evaluated.

Histogenesis of adenomatoid tumour associated to pseudofibromatous periorchitis in an infant with hydrocele.

An 18-month-old infant with recurrent congenital hydrocele presented with a mass in the caput epididymis. The tumour and several fragments of the tunica vaginalis were removed and studied by light and electron microscopy. The tumour showed the characteristic histological pattern of an adenomatoid tumour of mesothelial origin. The histological appearance of the tunica vaginalis was not uniform; some areas resembled the adenomatoid tumour to the epididymis, others exhibited histological and ultrastructural features of a haemangioma, whilst elsewhere, the two patterns were intermingled. Finally, areas of pseudofibromatous periorchitis with vascular proliferation and slit-like structures lined by mesothelial cells were recognized. These features suggest that the adenomatoid tumour originated from a localized reactive process with inflammation and vascular proliferation enclosing occasional slit-like structures originating from the mesothelial lining of the tunica vaginalis. Subsequent regression of vascular proliferation and inflammatory infiltration and continued mesothelial proliferation would give rise to the typical mesothelial pattern of adenomatoid tumour.
