Exophthalmos and blindness disclosing an ethmoidal-maxillary malignant non-Hodgkin's T-cell lymphoma. Apropos of a case]

BACKGROUND: We report a case of non-Hodgkin's malignant lymphoma of the cervicofacial region revealed by unilateral exophthalmos and blindness, an unusual mode of expression. CASE REPORT: A 40-year-old man with a 4-month history of diabetes mellitus had suffered from exophthalmos and blindness of the right eye for 20 years. Physical examination showed a homolateral hemifacial tumefaction and ophthalmoplegia. The right ocular fundus showed papillar edema and non-proliferative diabetic retinopathy. The left eye was normal. The otolaryngology explorations revealed a voluminous tumor in the anterior nasal cavity and in the cavum. Two biopsies were performed. Histology reported non-Hodgkin's T-cell lymphoma. Orbitocerebral and cervicofacial computed tomography visualized the aggressive ethmoidomaxillary extension with intraorbital and intracranial involvement. Chemotherapy (CHOP) combined with radiotherapy led to tumor regression and involution of the exophthalmos. Diagnostic difficulties, management and prognosis are discussed.     

Guaianolides from Lactuca saligna

The phytochemical investigation of the aerial parts of LACTUCA SALIGNA L. revealed the presence of lactucin, lactucopicrin, and a new guaianolide named 11beta,13-dihydrolactucopicrin. The structural configuration was established through spectral data.     

Pseudo-tumoral osteomyelitis. Immunologic study and etiopathogenic approach. Apropos of 2 cases]

Two cases of pseudo-tumoral osteomyelitis are reported. The first concerns a 12 year-old boy who presented with pain of the left knee during 8 months and, later on, with swelling of the upper extremity of the left leg, without fever or local inflammatory signs. The radiological aspect of condensation with a filling defect and "chimney" crossing the cartilage led to osteotomy. Local bacteriological samplings were normal. The second case concerns a 11 year-old boy who, after having complained from pain of the right wrist during 2 weeks, presented with swelling and on X-ray films a picture of metaphyso-epiphyseal lysis and an aspect of sequestrum in its center. There was no biological sign of inflammation. Evolution was favorable after antibiotic treatment and immobilization. In both cases, an immunological study showed an activation syndrome of the immune system with increased serum IL-1, IL-2 receptors and class II antigen receptors on the surface of T cells, suggesting a previous immunization of both children towards staphylococcus and, thereby, the subacute nature of evolution.     

Nosocomial outbreak of acute gastroenteritis in a neonatal intensive care unit in tunisia caused by multiply drug resistantSalmonella wien producing SHV-2 beta-lactamase

In a Tunisian hospital 27 babies, including 12 who were premature, in a single intensive care unit suffered acute gastroenteritis in the period from January to May 1988. The mean age at the onset of gastroenteritis was 8.4 days; nine babies died.Salmonella wien was isolated from stools (all babies) and blood (4 babies). It was also isolated from the stools of one nurse and from a mattress. Twelve of the babies had received cefotaxime, which was successfully replaced by oral colimycin. The outbreak was stopped by the implementation of infection control measures. All isolates ofSalmonella wien were of the same biotype, and had the same antibiotic resistance pattern (third generation cephalosporins, monobactams, aminoglycosides, chloramphenicol, trimethoprim and sulphonamides) and plasmid DNA restriction pattern. The isolates were all susceptible to a combination of cefotaxime and clavulanic acid (a -lactamase inhibitor), which displayed synergy, suggesting the presence of a -lactamase (geometric mean MICs 11.24 µg/ml for cefotaxime alone and 0.24 µg/ml in combination with 0.1 µg/ml potassium clavulanate). All isolates produced TEM-1 and SHV-2 -lactamase which was not transferable toEscherichia coli by conjugation. The presence of the SHV-2 enzyme inSalmonella wien may allow it to adapt to newer -lactams which is a cause for concern in this hospital.     

A new technique for double lung transplantation. "The bilateral single lung transplantation". Apropos of ten operations]

The technique of enbloc double lung transplantation described by the Toronto team, with cardiopulmonary bypass, cardioplegia, and tracheal suture is complicated by problems of tracheal anastomosis for its authors. Single lung transplantation has a more straight forward postoperative course and bronchial complications are moderate. We present a new technique of lung transplantation, the "bilateral single lung transplantation". It consists, via a single anterior horizontal incision, of successively performing two single lung transplantations without bypass. This operation has been performed ten times since November 1989. As expected, bronchial healing has been excellent.     

Secondary traumatization among wives of PTSD and post-concussion casualties: distress, caregiver burden and psychological separation

This study has two aims. First, it assesses the implication of husbands' post-traumatic stress disorder (PTSD) and post-concussion syndrome (PC) on their wives' sense of burden and emotional distress. The second aim was to examine the implication of the women's separation-individuation on their adjustment. Sixty women participated in study: 20 women married to war veterans diagnosed as suffering to PTSD, 20 women married to war veterans suffering from PC, and 20 women married to healthy controls. Data was collected using self report questionnaires assessing psychiatric symptomatology, caregiver burden and psychological separation-individuation. Results indicate that women from both research groups suffer from higher levels of burden and distress than controls. The level of separation-individuation was found to be correlated to levels of burden and distress. The complex implications of living with a traumatized spouse are discussed.
