[Absence of subrenal inferior vena cava revealed by rupture of duodenal varices in an adult].

This report concerns a case of absence of caudal inferior vena cava revealed by gastrointestinal bleeding from isolated duodenal varices by an adult. The diagnosis of duodenal varices was performed by ultrasonographic endoscopy. Development of duodenal varices in absence of portal hypertension is uncommon. Involvement of cavo-portal collateral circulation in case of inferior vena cava obstruction is unusual and duodenal varices are still more rarely encountered. Diagnosis was ultimately supported by femoral venous angiography showing the absence of inferior vena cava and a venous return from the right lumbar vein into the portal vein via the duodenal varices. The absence of caudal portion of inferior vena cava is more probably related to neo-natal thrombosis than to a true atresia.

Recent developments in medical therapy of POAG with beta blocking agents.

Since 1987, an entirely computerized open study has been developed in Pr Sole's Ophthalmology Department: the CLERTORE project (Clermont-Tonus-Research). It is a data bank including all the ophthalmic data of hypertensive patients, whether treated or untreated. Every six months, the patients included in the CLERTORE project undergo a clinical ophthalmic examination as well as an automated visual field examination (OCTOPUS 500), an examination of the optic disc (ONHA) and fluorophotometry (FLUOROTRON MASTER). To date, 92 patients have been included in the project. One hundred and eighty-three eyes are examined every six months with a maximal follow-up of 42 months. Because of the numerous criteria of the data base, it is too early to give any statistical results. With a close look at the evolution of the examinations of some of our cases, this preliminary work however allows us to make the three following remarks: In the hypertensive patients, a modification of the papillary pallor is observed without any change in the visual field, C/D ratio and fluorophotometry. The pallor is clearly modified when adrenaline eye drops are given to glaucomatous patients. There is a break of the iridic blood barrier in some hypertensive patients, whether treated or untreated.

[Jejunal secretion of immunoglobulins and secretory component in three patients with primitive humoral immunoglobulin deficiency].

Jejunal secretion of albumin, immunoglobulins and secretory component was studied using the segmental perfusion technique with an occluding balloon, in two patients with common variable hypogammaglobulinemia and one patient with selective immunoglobulin A deficiency. Results were compared with those of twenty-two controls previously studied under the same conditions. In all three cases, jejunal secretion rate of immunoglobulin A was nil and secretion rates of albumin and immunoglobulin G were increased as compared to controls. Jejunal secretion rate of immunoglobulin M was increased in the patient with selective immunoglobulin A deficiency, normal in one case of common variable hypogammaglobulinemia and almost nil in the other case. Secretory component was secreted in the jejunal lumen mostly or exclusively under a free form depending on partial or total absence of immunoglobulin A and M. This study allowed to confirm in vivo that secretion of secretory component is independent of the presence of immunoglobulins. Intestinal perfusion might be a useful tool in the investigation of immunological diseases of the intestinal tract.

[Functional and motor study of retrosternal esophageal plasties].

The stomach may be used for esophageal reconstruction after resection of esophageal cancers. The aim of this study was to assess the motility of retrosternal esophagoplasty (RO) following the Akiyama procedure in 6 men (mean age: 56.7 years), at least two months after surgery by means of two techniques: a) manometry of the transplant with a multilumen perfused catheter in 50 and 40 cm from the incisor teeth including spontaneous (5 min) and poststimulation recordings, b) an isotopic method for assessing the gastric emptying of a meal labelled with 111In for the liquid phase and with 99mTc for the solid phase, compared to 12 volunteers as controls. Baseline pressure was 11.2 +/- 2.4 H2O cm without spontaneous activity. After dry and wet deglutition (5 ml of water), 6 patients showed synchronous rise in pressure, having mean amplitude of 12.7 +/- 2.3 cm H2O and lasting 4.3 +/- 1.2 s. Liquids T1/2 was 16.2 +/- 7.8 min in controls (p less than 0.01) and solids T1/2 was 17.7 +/- 6.4 min vs 61.7 +/- 16.5 min (p less than 0.001). The lack of propagated activity associated with rapid emptying of the meal through the plasty with no discrimination between solids and liquids suggests that RO does not participate actively in digestion.

Paraneoplastic intestinal pseudo-obstruction as the presenting feature of small-cell lung cancer.

A previously healthy 50-year old man presented with acute small bowel obstruction. No etiology was found at laparotomy. Postoperatively, the patient remained symptomatic with nausea, vomiting and severe constipation. Gastroscopy revealed retained food in the stomach. Gastric emptying of solids and liquids was dramatically decreased at scintigraphy. The colon was dilated on X-ray study. Chest X-ray revealed a pneumopathy and a small-cell lung cancer was discovered at bronchoscopy. The patient died 5 months after onset. Histologic study of the gut showed widespread degeneration of the myenteric plexus with plasma cell infiltration, Schwann cell proliferation and a reduced number of neurons of which many were abnormal. Intestinal pseudo-obstruction can reveal a small-cell lung cancer; the mechanism of neuronal impairment leading to pseudo-obstruction remains unknown, but could be related to the pathophysiology of paraneoplastic syndromes.

[Esophageal cancer and endoscopic sclerosis of esophageal varices: a fortuitous association?].

We report the case of 4 male patients, smokers, with alcoholic cirrhosis, mean age 54.7 +/- 6 years, treated by sclerotherapy for bleeding esophageal varices. Variceal eradication was obtained following juxtacardial intravariceal injection of 1.5 p. 100 polidocanol in one case (100 ml), and 0.5 p. 100 polidocanol in 3 cases (90, 240 and 310 ml). Local complications were observed in all patients (ulcers: 3; stenosis: 1). Carcinoma of the lower third of the esophagus was detected 12, 20, 22 and 30 months after esophageal sclerosis. Carcinoma was circular (one case), semicircular (2 cases), and nodular superimposed on Barrett's esophagus (one case). Histologic features included squamous cell carcinoma in 3 cases and adenocarcinoma in one case. Sclerotherapy could lead to the development of carcinoma because of mucosal alterations. However, other high risk factors (age, alcohol-tobacco intoxication, Barrett's esophagus) and different histologic features suggest a causal association. Endoscopic follow-up of patients after esophageal sclerosis could confirm this hypothesis.

[Prenatal echographic diagnosis of iniencephaly. Apropos of a case].

Iniencephaly is a rare lethal malformation. It is associated with a defect in the occiput, alterations in the spinal column that are variable and retroflexion of the fetus. Antenatal diagnosis by ultrasound is possible because of the typical appearance: the fetal head is hyperextended, with distortion and shortening of the cervical spine. The occiput can be fused with lower vertebrae. Many associated malformations may be found: polyhydramnios, neurologic, facial and visceral abnormalities.

[Fluorophotometry by instillation. II. Effect of beta-blocker eyedrops in the normal subject].

The effects of various drugs on the human aqueous humor flow were studied by the fluorophotometric method of Yablonski (topical fluorescein instillation). The effect of the beta-adrenergic blocker (Timolol) on aqueous humor flow and on intra-ocular pressure has been studied in ten normal eyes on the Fluorotron Master. We found that the acute decrease in intra-ocular pressure was equal to 1.39 +/- 0.44 microliter.min-1 for the Timolol treated eyes, and equal to 2.79 +/- 0.57 microliter.min-1 for the untreated eyes (Placebo). The difference between Timolol and Placebo was statistically significant (Student t-tested, and Wilcoxon W-tested). The fluorophotometric method is superior to the tonographic method by giving a more favorable condition to study the facility of outflow in steady physiological state. Our results are in good agreement with other authors and show Timolol to have little or no effect on the facility of outflow.
