[Abdominal actinomycosis. Three cases].

BACKGROUND: Abdominal actinomycosis is a suppurating affection caused by a positive Gram germ, Actinomyces israelii. Manifestations of this rare disease are usually pseudotumoral syndromes leading to surgical exeresis. The diagnosis is obtained from the histologic report. CASES REPORT: We report three cases in all of which this disease presents with tumoral symptoms. The first affected the sigmoïd, the second affected the mesentery and the last affected the greater omentum and abdominal wall. In no case, the diagnosis was done before surgery. In 2 of the cases reported here, the patients had an old, incontrolled intra-uterine device. DISCUSSION: From a review of the literature, we observed that the diagnosis of abdominal actinomycosis remains difficult. The radiologic findings are nonspecific. Actinomycosis is treated with prolonged antibiotics, and surgery is only needed in abdominal abscess and fistula. CONCLUSION: Theses observations illustrates the difficulties of the diagnosis of this rare unrecognized disease.

[Hydatid cyst of the thigh: three cases].

Three patients presented a benign soft tissue mass in the thigh muscles. Ultrasonography provided the diagnosis of hydatid cyst. Total pericystecomy was performed in all cases with no recurrence at 8 months, 3 years and 4 years. We point out the importance of preoperative diagnosis and the need for radical excision to avoid recurrence.

[Pterygium: surgical treatment].

PURPOSE: The surgical management of pterygium is often complicated by recurrence of disease. The goal of this study was to compare three different surgical techniques used for the treatment of pterygium. METHOD: We propose a prospective and partly retrospective study on 167 cases of pterygium 151 were primary and 16 were recurrent, treated between 1 January, 1995 and 30 June, 1998. The surgical treatment used of 3 different techniques: pterygium excision for 111 eyes, pterygium excision with conjunctival autograft for 29 eyes, pterygium excision with application of mitomycin C for 27 eyes. RESULTS: Immediate results for the three kinds of treatment were good. No serious complications were noted. Long-term results show a recurrence rate of 10.3% for conjunctival autograft, 11.1% for mitomycin C application, while the pterygium excision alone had a recurrence rate of 55.9%. CONCLUSION: This study demonstrated that conjunctival autografting and the application of mitomycin C are safe surgical techniques that reduce the probability of recurrence after surgery for pterygium. They can be recommended for young people and patients exposed to sun. Mitomycin therapy is the most appropriate treatment for these cases, because of its simplicity, lower lost and the relative lack of complication.

Associated primary esophageal and lung carcinoma: a study of 39 patients.

From 1979 to 1992, of 1,294 patients with esophageal squamous cell carcinoma, 39 patients (3.2%) (38 male patients, 1 female patient; mean age, 58 years) had associated primary lung carcinoma. Criteria for the diagnosis of primary lung carcinoma were: (1) non-squamous cell carcinoma tumors, (2) tumors existing before the esophageal squamous cell carcinoma, and (3) solitary squamous cell carcinoma presenting with endobronchial involvement. The two tumors were observed synchronously in 22 patients (56%) and metachronously in 17, with a mean tumor-free interval of 46 months (range, 18 to 77 months). In patients with synchronous disease, 10 underwent nonoperative treatment or a palliative surgical procedure, and 12 (55%) underwent a curative operation. In patients with metachronous disease, a curative operation was performed in all for the first tumor and in 9 (53%) for the second tumor. The overall postoperative mortality rate was 15%. Two patients (10%) died after the curative operation. None of the patients died who underwent curative esophagectomy combined with lobectomy. For the patients with synchronous disease, the 5-year survival rate was 11% in those who underwent a curative operation, and the longest survival in those who received palliative treatment was 18 months. For the patients with metachronous disease, the 5-year survival rates from the date of the diagnosis of the second tumor were 17% for those who had a curative operation and 11% for those who received palliative treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

[Abdominal cystic lymphangioma in children].

Cystic lymphangioma is a rare tumour (6% of benign tumours in children), frequently situated in the cervical or axillary region and exceptionally intraabdominal. It arises due to a congenital defect in the connection of the primary lymphatic channels with the central collecting system. It presents clinically either in the form of a pseudo-appendix or pseudo-ascites syndrome or in the form of an abdominal tumour with or without compression of adjacent structures. It can now be easily diagnosed by ultrasonography. Treatment is well defined and consists of surgical resection of the isolated lymphangioma or associated with the adjacent intestine, depending on the site of the tumour. It has a good prognosis.

Production of two species of interferon by Large White and Meishan pig conceptuses during the peri-attachment period.

Antiviral activities present in uterine flushings from pregnant Large White, Large White 'hyperprolific', and prolific Meishan gilts, between Days 8 and 20 of gestation were compared. Flushings (20 ml) from all gilts between Days 14 and 20 were positive in an in-vitro interferon (IFN) assay using vesicular stomatitis virus as a challenge infection. Highest antiviral activities (of up to 400,000-1,200,000 total Units/flushing) were obtained at Day 16 of gestation, i.e. clearly after the beginning of attachment. There was no major difference between breeds although, at Day 14, flushings from Meishan gilts yielded significantly higher titres than those from the other two, suggesting a correlation with the previously described earlier trophoblast elongation in Meishan gilts. Conceptus cultures contained antiviral activity, with values very close to those obtained in vivo, but the difference between breeds was not significant. Cultures from Day 20 on contained very little antiviral activity. The antiviral activity was associated with a mixture of at least two IFNs, one of which was IFN-alpha like, and the other was serologically identified as an IFN-gamma, that is an 'immune IFN', previously found to be secreted only by T lymphocytes. This finding may have implications for our understanding of the immunology of early pregnancy.

[A case of esophageal duplication discovered in a newborn].

A case of esophageal duplication discovered in the neonatal period is reported and discussed. This infrequent malformation (9% of all childhood mediastinal tumors) is an entoblastic duplication of the digestive tract and is often accompanied with spinal malformations. The duplication may be either cystic or tubular; the latter form usually opens into the normal esophagus. The most common clinical manifestations are respiratory symptoms caused by compression. The diagnosis, suggested by the findings on the plain chest film and osephageal opacification, is confirmed by the ultrasound examination and, above all, the CT scan. The treatment of this malformation is surgical. Reconstruction may be difficult but overall results and prognosis are excellent.

[Long-term outcome of surgically treated peptic ulcer. Review of a series of 419 patients operated for peptic ulcer].

The authors report an analysis of 419 cases of operated peptic ulcer. 68.78% of patients had a mean follow-up of 4 years. After clinical and endoscopic examination, the results of the survey were assessed on the basis of various parameters, which demonstrated that the results of surgery were related to socio-occupational problems, smoking, the site of the ulcer, the stage, the history of the ulcer prior to the operation, the conditions of the operation and obviously the surgical technique used.

[Value of posterior vertical lumbar incision in renal surgery. Based on a series of 1,126 cases].

The authors report their experience of 1,126 cases of posterior vertical lumbar incision. The essential indication for this approach is stones in the renal pelvis or lumbar ureter (788 cases). The authors subsequently extended the indications for this incision to all plastic operations on the pyeloureteric junction (56 cases) and the extraction of certain staghorn calculi (114 cases). The posterior approach is anatomically simple and direct. It has the advantage of causing less muscular mutilation with a simpler postoperative course.

Interferon-gamma gene and protein are spontaneously expressed by the porcine trophectoderm early in gestation.

The nature and the source of the antiviral activity found in the reproductive tract of pregnant gilts early in gestation were analyzed. Two antigenically distinct antiviral activities were found in uterine flushings and in supernatants of conceptus-conditioned culture medium between days 12 and 20 of gestation, using Madin Darby bovine kidney cells and vesicular stomatitis virus as a challenge in the antiviral bioassay. One component was antigenically identified as interferon-gamma (IFN-gamma). Northern blot analysis of conceptus poly(A)+ RNA with a human IFN-gamma cDNA probe revealed two mRNA of 1.3 and 1.4 kb. In addition, immunoprecipitation of metabolically labeled conceptus secretory proteins with an antiserum raised against purified porcine rIFN-gamma resulted in four bands in sodium dodecyl sulfate-polyacrylamide gel electrophoresis, with molecular mass 18.5 to 24.5 kDa. Pre-electrophoresis incubation of the immunoprecipitate with glycopeptidase F, which removes N-linked carbohydrates, yielded a single band of 16.5 kDa. Finally, staining of ultrathin sections by indirect immunofluorescence using the same antiserum to rIFN-gamma revealed that all cells of extra-embryonic trophectoderm contained intensely fluorescent granules in their apical cytoplasm. Neither endoderm nor embryonic cells stained positive. These results clearly show that IFN-gamma, known so far as a T or NK cell-derived lymphokine, is spontaneously and intensively secreted by the porcine trophectoderm, an embryonic tissue not related to the hematopoietic lineage. They also suggest that the implanting conceptus, at least in the porcine species, could play an active role in immune interactions with the mother.

[Posterior vertical lumbotomy in pediatric practice. Apropos of a series of 294 cases].

The study involves 294 cases. Essentials indications of posterior approach were for pelvic stones or lumbar ureteral stones 198 cases. Theres used this approach for abnormalities in the uretero-pelvic-jun (32 cases) and some staghorn srones (24 cases). The lateral posterior vertical lumbotomy passesses the advantage over classical lateral lumbotomy of being less disturbing to muscle, being less painful postoperatively stay.
