[Effect of scleral indentation on the corneal topography and the axial length after retinal detachment surgery. A prospective study in 30 cases].

INTRODUCTION: Scleral indentation is an essential time in conventional retinal detachment surgery. It enables re-establishing retinal contact and to counterbalance vitreal tractions. It can be circular, segmental or radial. Silicone materials are often used. MATERIALS: In a prospective study, we followed up 30 eyes of patients who underwent retinal detachment surgery. We analyzed changes in corneal surface using differential map of the corneal (induced astigmatism, meridian axial deviation) and change in the axial length of the globe. RESULTS AND DISCUSSION: Follow-up examination showed corneal astigmatism: 2.62 diopter (D) at one week, 2.37D at one month and 1.80D at 3 months. Corneal axis meridians changed: 25 degrees at one week and 18.6 degrees at 2 months. Axial length was also modified. We observed a lengthening: 1.7mm during the first week which remained unchanged at 1.63 after 2 and 3 months. These changes were studied according to the different techniques used in our study and were compared with results reported in the literature. CONCLUSION: We think that conventional retinal detachment surgery causes modifications in refractis (induced astigmatism and axial lengthening).

[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.

Hypertension in primary chronic glomerulonephritis analysis of 359 cases.

The incidence of hypertension was evaluated in 359 patients with primary chronic glomerulonephritis who underwent renal biopsy. It was compared to a control group of 7,468 subjects who were obtained from an epidemiologic study performed in the same area at the same period. The prevalence of hypertension was 42%. On the basis of multiple regression analysis, the level of blood pressure was shown to be positively correlated to four independent variables: age, body mass index, degree of renal insufficiency and presence of proliferative glomerulonephritis. It was concluded that, although renal insufficiency increases the incidence of hypertension, proliferative lesions play an important contributive role in the development of hypertension.

Embolization of cardiac myxomas masquerading as polyarteritis nodosa.

Cardiac myxomas are rare tumors which can mimic other diseases. We describe a 19-year-old man who presented clinically with polyarteritis nodosa (PAN). Muscle biopsy showed vasculitis, but corticosteroid and immunosuppressive therapy was initially effective. Cardiac myxomas were found by echocardiogram when the disease relapsed and were resected surgically. Segmental arterial aneurysms and stenoses were found on angiography after leg ischemia. We suggest that echocardiography should be performed in all cases of clinically suspected PAN.

[Membranoproliferative glomerulonephritis in 2 brothers].

In one sibship, two brothers had membrano-proliferative glomerulonephritis type I. The former died 3 years after the onset of the glomerulonephritis and the latter is still alive. The familial nature of the disease is an argument to strengthen the concept that genetic factors are involved in its origin.

[Atypical metastases disclosing vesicular carcinoma of the thyroid].

Differentiated carcinoma of the thyroid may generate bone or lung metastases. Some times, thyroid cancer remains latent, and is revealed by the presence of secondary bone tumors. In the present paper, we relate our personal experiences with two patients who had thyroid cancer diagnosed indirectly through the occurrence of distant metastases. The secondary tumors were localized in the right frontal sinus and the cranial vault, respectively. We discuss the diagnostic and therapeutic problems involved with such metastases. We further present a review of the literature dealing with this topic.

[Continuous ambulatory peritoneal dialysis in Tunisia].

CAPD covers about 4% of renal replacement therapy patients in Tunisia. From February 1983 to 1988, 47 patients, 21 males and 26 females whose mean age was 36, 14 +/- 15 were treated. Their socio-cultural level was variable. The mean duration of therapy was 14.5 months/patient/year. The five years patient survival rate was 46% and the technique survival rate 21%. Most patients had a good general condition and were professionally rehabilitated. Peritonitis was the main complication: its incidence was 1.8 episodes/patient/year. Yeasts peritonitis were relatively frequent, specially in patients who had previously been treated with antibiotics. Peritonitis was often cured with a local and general treatment. Yearly CAPD cost was 1/3 lower than center hemodialysis and a better management allowed to decrease the expenses due to laboratory and X ray investigations and to hospitalization. On the basis of this clinical experience, we believe that CAPD is an efficient and valid therapeutic modality, less expensive than hemodialysis. It is probably a suitable renal replacement therapy in other centers in Tunisia and in other developing countries.

[The first thirty months of kidney transplantation in Tunisia].

Kidney transplantation is actually the best replacement therapy for the end stage renal failure. It sets free the hemodialysed patient from the hemodialysis restraint and contributes to solve the socio-economic problems risen by chronic hemodialysis. The authors report the results of this technic during the first 30 months of kidney transplantation in the "Hôpital Charles Nicolle" of Tunis. They describe the first steps which led to kidney transplantation, the therapeutic regimens, the medico-legal problems and the specific complications observed during this start period.

[Intraorbital involvement in multiple myeloma].

According to data from the literature, intraorbital involvement in multiple myeloma is rare. Such involvement may result in exophthalmia, itself the first manifestation and presenting feature of myeloma. These lesions can respond remarkably to radiotherapy. The authors present a new case report.

[Involvement of the cranial nerves disclosing multiple myeloma].

Diseases of cranial nerves are very seldom associated with multiple myeloma. However, their occurrence as a harbinger of multiple myeloma seems to bear a particular significance and is worth mentioning. In the present paper, we discuss two cases in which disorders of cranial nerves heralded Kahler's disease. The patients presented with posterior laterocondylar space and cochleovestibular (otoliquorrhea) syndromes, respectively. We stress the diagnostic problems involved and analyze the pathogenesis of diseases of the nervous system associated with multiple myeloma. Diseases of cranial nerves are seldom associated with multiple myeloma. Nonetheless, the clinical setting and laboratory tests will direct the diagnosis. The same does not hold true when one is confronted with Collet-Sicard's syndrome or cochleovestibular syndrome accompanied by otoliquorrhea.

[Antibodies against extractable nuclear antigens. Clinico-biological correlations in 100 cases].

The clinical significance of antibodies directed against extractable nuclear antigens with currently well-known antigenic targets, is studied in 100 patients affected with various connective tissue inflammations. The anti-Sm is the most frequently encountered antibody in lupus disease and overlapping connective tissue inflammations with a lupus component while the anti-RNP is related to mixed inflammation of the connective tissue and the dry syndrome. These antibodies, without being specific markers for a given disease, represent an additional biological argument for a better nosological classification of connective tissue inflammations. The use of immuno-impression, a more sensitive technique than immunodiffusion, could provide a better understanding of the immune response during these diseases and specify the diagnostic and prognostic value of various auto-antibodies. Analysis by immuno-impression of 36 sera among the 100 with antibodies directed against extractable nuclear antigens has enabled us to compare the two techniques and study the different specificities of these antibodies.
