Exclusive elemental enteral diet in cortico-resistant and cortico-dependent forms of Crohn's disease

The aim of this study was to investigate the value of elemental diet in steroid-resistant and steroid-dependent Crohn's disease. Elemental diet (Vivonex HN, 39.4 +/- 9.2 kcal/kg/d) was delivered through a nasogastric tube at a constant rate. Twenty therapeutic periods lasting from 20 to 74 days (median, 32 days) were undertaken in 18 patients. Elemental diet was well tolerated. Mean values of hemoglobin, serum albumin, and serum transferrin increased significantly through the therapeutic period; body weight and anthropometric data did not change significantly. The short-term response to elemental diet was excellent in 11 cases, demonstrated by achievement of clinical remission and steroid withdrawal; six patients had an incomplete remission and remained slightly active or had to be maintained under low dose steroids; three patients did not respond to therapy and had to be operated upon. During the follow-up (6-30 months), 8 patients out of 17 had a relapse. Relapse was controlled by medical therapy in 5 cases and led to surgery in the 3 other cases. We conclude that elemental diet, as total parenteral nutrition, is an effective therapy of steroid-resistant and steroid-dependent Crohn's disease. However, elemental diet does not prevent relapse.     

Bronchial and cardiovascular effects of ocular topical B-antagonists in asthmatic subjects: comparison of timolol, carteolol, and metipranolol

B antagonists eye drops are most effective for the treatment of chronic open angle glaucoma. By this way of administration they have a very good systemic bioavailability. Bronchial, and cardiovascular effects of three of these topicals: timolol, carteolol and metipranolol have been evaluated in three parallel groups of asthmatic patients. The three topics induce bronchoconstriction without significant difference between them, and lower heart rate (sometimes very intensely) whatever the B antagonist studied. From these data, it is recommended to practitioners to follow carefully the rules of administration of B blockers, even in eye drops.

Leflunomide-induced peripheral neuropathy.

Two cases of leflunomide-induced peripheral neuropathy are described; in a 60-year-old woman with sero-negative polyarthralgia-myalgia syndrome and a 65-year-old man with sero-negative rheumatoid arthritis, both treated with leflunomide at 20mg/day. Nerve conduction studies and electromyogram showed sensorimotor axonal neuropathy in both cases. An alternative cause for the axonal neuropathy was excluded by extensive investigations, including cerebrospinal fluid examination and nerve biopsy in the second patient. Both patients stabilized symptomatically and electrophysiologically upon cessation of leflunomide. It is possible that leflunomide-induced peripheral neuropathy has been under-reported and under-recognized.     

Enterobacteriaceae isolated in nine general hospitals of the Ile-de-France in 1988 and 1989: susceptibility to beta-lactam antibiotics according to the length of hospitalisation

Susceptibility to beta-lactam antibiotics of strains of Enterobacteriaceae consecutively isolated in nine general hospitals during a period of 2 months (march and april) has been studied by the disk-agar diffusion method. The separation between susceptible and resistant strains was based on the measure of the inhibition zones centered by 2 disks: cephalothin and ticarcillin. Enterobacteriaceae were divided in 2 groups: strains isolated during the first 48 h of hospitalisation or isolated after. Fifty one per cent of the strains were isolated during the first 48 h: they did not belong to the residential flora of these hospitals. Klebsiella, Proteus indole positive, Providencia, Enterobacter, Serratia were more frequently isolated after 48 h of hospitalisation. Susceptible strains of Klebsiella, Proteus indole positive, Providencia, Serratia were more rarely isolated after 48 h of hospitalisation. E. coli whatever the duration of hospitalisation, is the less frequent susceptible bacterium.     

Comparison of microsurgical vasovasostomy techniques in the rat

We compared three different microsurgical vasovasostomy techniques on the rat vas deferens using absorbable and non-absorbable sutures and a fibrin adhesive technique. The best method was an extramucosal technique over a splint using vicryl. The worst results were seen using adhesive.     

Orbital and muscular relapse of Burkitt's lymphoma

We report the case of a child presenting with abdominal Burkitt's lymphoma in whom a relapse presented as orbital and muscle involvement. This clinical feature is extremely rare. Two muscle and one orbital biopsies were necessary to obtain proper diagnosis. A new extension check-up showed bone marrow invasion and normal cerebrospinal fluid. This relapse was successfully treated by conventional chemotherapy and consolidated with high-dose chemotherapy, total body irradiation and autologous bone marrow transplantation. Eighteen months after transplantation, the child may be considered as definitively cured.
