Unclassifiable high grade malignant T-cell lymphoma with clonal evolution.

We report a case of leukemic malignant T-cell lymphoma with mixed small and large cells. The small cells displayed a mature CD8-positive phenotype, a diploid DNA distribution by cell cycle analysis, and structural karyotypic abnormalities. Large cells were near triploid, showed additional structural cytogenetic abnormalities and a more immature membrane phenotype without CD8 expression. Altogether, these data provide suggestive evidence for a clonal evolution from a mature small cell T-cell lymphoma to a more immature large cell proliferation.

Treatment and long-term outcome of chronic radiation esophagitis after radiation therapy for head and neck tumors. A report of 13 cases.

The natural history of chronic radiation esophagitis occurring in previously normal esophagus is still unknown. We describe here the long-term outcome of chronic esophagitis arising after neck irradiation for oropharynx and larynx carcinomas in 13 consecutive adult patients. The first clinical signs of radiation esophagitis were dysphagia or impossibility of oral intake, which appeared within 26 months (range 2-120 months) after the end of radiation for pyriform fossae carcinoma (N = 5), tonsil carcinoma (N = 2), larynx carcinoma (N = 2), pharynx carcinoma (N = 2), base of the tongue (N = 1), and thyroid carcinomas (N = 1). During upper endoscopy, an esophageal stenosis was found in 11 cases and was associated with ulceration in three cases. An isolated esophageal ulceration was present in only two cases. Chronic radiation esophagitis diagnosis was confirmed by histology and surgery in seven cases. In the last six cases, diagnosis was supported by the absence of first cancer relapses within a median follow-up of two years (16 months to nine years) and by endoscopic findings. Seven patients received parenteral or enteral nutrition. Ten patients were treated by peroral dilatations. These treatments allowed nearly normal oral diet in 11/13 patients. Only one patient was lost of follow-up after 20 months. Four patients died from chronic radiation esophagitis. One of these patients died from massive hemorrhage after peroral dilatation. Four patients died of a second carcinoma with no first cancer recurrence. Four patients were alive after six months to nine years of follow-up. Moderate dysphagia was still present, allowing nearly normal oral feeding.(ABSTRACT TRUNCATED AT 250 WORDS)

Prostaglandin-induced antral hyperplasia in neonates: clinical experience and dose-response characteristics.

Antral hyperplasia (AH) induced by prostaglandins (PG) has been described by us recently in 5 infants with cyanotic heart disease receiving the drug. The purpose of the present study was to analyze 14 infants diagnosed as having AH either sonographically or pathologically in an attempt to characterize the dose-response characteristics of this adverse drug reaction, its clinical course and its optimal management. Infants with AH exhibiting large gastric aspirates have received a significantly lower cumulative dose (1,633 +/- 1,266 micrograms/kg) than those presented also with a palpable mass (3,458 +/- 1,703 micrograms/kg), (p < 0.01). While in general there is a dose-related clinical toxicity, variability in the location of the hyperplasia can explain cases of no apparent obstruction despite large cumulative doses of PG. In asymptomatic cases the antral hyperplasia, although visualized, it did not result in gastric outlet obstruction. In all cases followed by us to date, discontinuation of the PG has resulted in resolution of the clinical and sonographic findings. Nasojejunal tube was successfully attempted in several cases, preventing surgery in these very-high-risk infants.

[Nasosinusal schwannoma. Apropos of 2 cases. Value of nasal endoscopy for diagnosis and treatment].

Two cases of paranasal schwannomas are reported. These tumors are rare. Its symptomatology is no specific explaining the late diagnosis. The contribution of radiology and endoscopy for this pathology is analysed. Ct scan and MRI state precisely the extension and the relations of the tumor. Endoscopy improves the endonasal exam pre and post operative and may be an option for the surgical treatment of these tumors. In connection with that we present an original approach of the pterygopalatine fossa under endoscopic control via the middle meatus.

[Inflammatory polyp: a rare benign endobronchial tumor].

We report a case of inflammatory polyp in a male patient, which was totally obstructing the left main bronchus but could be removed by simple endoscopic traction. The polyp was responsible for an absence of left lung ventilation which in turn produced by reflex an absence of left lung perfusion completely reversible after removal of the polyp. Inflammatory polyp is a rare benign tumour. Its physiopathology is controverted, but it seems to result from local irritation of the bronchial mucosa. Bronchial endoscopy is the essential examination which in most cases make it possible to diagnose and treat the tumour.

Recurrent ctb(7)(q31.3) and possible laminin involvement in a neonatal cutis laxa with a Marfan phenotype.

A 6-week-old girl presented with cutis laxa, emphysema, heart anomalies and a diaphragmatic hernia. She died at 22 weeks. A recurrent ctb(7)(q31.3) was found and the laminin gene was suspected to be involved in the disease. Anti-human laminin antiserum showed that this protein was absent from the skin. This case, together with 17 other similar cases, could represent a new type of connective tissue disease.

The estrogenic activity of certain phytoestrogens in the Siberian sturgeon Acipenser baeri.

Various phytoestrogens such as formononetin, daidzein, genistein and equol were synthesized. Their purity was assessed by various analytical techniques including melting point determination, thin-layer chromatography (TLC), infra-red spectra (i.r. spectra), nuclear magnetic resonance (1H- and 13C-NMR) and gas chromatography coupled with mass spectrometry (GC-MS). The estrogenic activity of these compounds, as well as biochanin A and coumestrol, was biologically tested by the induction of vitellogenin secretion in yearling sturgeon and compared to the activity of estradiol-17 beta. Pure daidzein, biochanin A, genistein, equol and coumestrol all had estrogenic activity as assessed by their induction of hepatic synthesis of vitellogenin when administrated intraperitoneally to yearling Siberian sturgeon. Coumestrol seemed to be the most potent compound, inducing the most vitellogenin secretion with the lowest dose administered. Formononetin was inactive when administered by the intraperitoneal route. All the phytoestrogens tested were considerably less potent than estradiol-17 beta.

[Articular manifestations in Wegener's disease. Report of 13 cases].

Seventeen cases of Wegener's granulomatosis have been reviewed in search of articular involvement. Articular symptoms were present in 13 cases (76 p. cent), and were inaugural in 9 cases (53 p. cent). Six of these patients experienced arthralgias, which were most often migratory, and were inaugural in 3 cases. Seven patients had arthritides, which were inaugural in 6 cases; they were fixed and additive in 6 of these 7 cases, making up a distal polyarthritis in 3 patients, and an oligoarthritis in the 3 other ones; they were transient and migratory in 1 case. The 3 cases of distal polyarthritis were inaugural and fulfilled the ARA criteria for rheumatoid arthritis; two of them were accompanied by nodules which were quite identical to rheumatoid ones. There was no axial involvement. Joint involvement was not destructive and had a favourable course under disease treatment. Myalgias were present in 3 cases, one of which simulated Horton's disease. Biological manifestations chiefly consisted of marked inflammatory changes. Antineutrophil cytoplasm antibodies were present in 11 out of 16 patients in whom they were searched; among 6 of these patients who had active disease, they were present in 5. The antibody level decreased as treatment reduced disease activity and suppressed joint involvement. Joint involvement in Wegener's granulomatosis seems to be the inconstant hallmark of disease activity. It requires no specific treatment.

[Intestinal perforation occurring at the beginning of treatment: a severe complication of bacillary tuberculosis].

We report 2 cases of intestinal perforation caused by tuberculosis and affecting the small intestine in one case and the colon in the other case. The patients were men aged 49 and 51 years respectively. Both were cachectic and presented with advanced open pulmonary tuberculosis. Perforation in free peritoneal cavity occurred 2 and 8 days respectively after an antituberculous treatment was initiated. The outcome was rapidly fatal in both cases. Tuberculous enteritis has become rare, but it can still be observed in patients with severe open pulmonary tuberculosis, where the gastro-intestinal tract is contaminated by the large number of virulent mycobacteria swallowed. In such patients clinicians must be alert to abdominal premonitory signs. Intestinal perforations in free peritoneal cavity are uncommon. Most perforation are small, single or multiple, and located on the antimesenteric side of the terminal ileum. They may occur at any time, and particularly just after an antituberculous therapy has been instituted. Clinical presentation is one of acute peritonitis requiring emergency laparotomy. Mortality has been reduced by technical improvements, notably temporary enterostomy, but perforation remains a serious and often fatal complication of tuberculosis in patients with severe malnutrition.

[Epidermoid carcinoma of the external auditory canal].

The squamous cell carcinoma of the external auditory canal is extremely rare. The facial paralysis is usual, but pain seems to be the most common symptom. The mean age at diagnosis is 50 to 60 years, with chronic external otitis preceding. The CT-scan is the most important investigation before treatment: surgery and external radiotherapy. Surgical procedure must be large, with or without facial nerve dissection, following by irradiation of the temporal bone and cervical nodes. The generally poor prognosis is explained by the frequency of advanced disease at the time of diagnosis. This paper reports our 4 experiences, with a bilateral carcinoma case.

[Systemic mastocytosis disclosed by rupture of esophageal varices].

A 77-year-old woman had variceal bleeding related to systemic mastocytosis. Physical examination revealed minimal ascites and mild hepatomegaly noted 11 years before. Liver function tests were nearly normal. Because of early recurrent bleeding, a mesocaval shunt was performed. Wedged liver biopsy showed a moderate fibrosis of portal tracts and massive mast cell infiltration within portal tracts and sinusoids. Perisinusoidal collagen deposition was demonstrated ultrastructurally. We suggest that systemic mastocytosis be added to the list of diseases related portal hypertension with perisinusoidal fibrosis. As there is currently no specific treatment, a portocaval shunt should be discussed.
