[Plasmocytic pleural effusion disclosing multiple myeloma].

Pleural effusion caused by plasma cell involvement in multiple myeloma has been reported unfrequently, and has been described at a frequency below 1% of multiple myeloma. In this study, we report an observation with pleural effusion as first symptom of multiple myeloma. The analysis of the pleural liquid showed plasma cells with a monoclonal IgG Kappa immunoglobulin. In addition, there was a bone marrow infiltration by plasma cells, a serum monoclonal immuno-globulin of the same type and osteolytic lesions. Our patient has received one course of chemotherapy with: vincristine, melphalan, cyclophosphamide and prednisone. The patient did not respond to the therapy and died one month later. Pleural effusion seems to be an expression of aggressive myeloma. Survival exceeds rarely 4 months.

[Prevalence of hemoglobin abnormalities in Kebili (Tunisian South)].

BACKGROUND: Hemoglobin abnormalities constitute a public health problem in many countries in the world. In Tunisia, these disorders were thought to affect only the North-western population. However, the existence of hemoglobinosis concentration in Kebily in south Tunisia has been suggested by previous work. In order to estimate their frequencies, we performed a screening of hemoglobin abnormalities in the North-Kebili region, to establish a prevention program of the homozygous forms. METHODS: This screening concerned all 1st and 2nd grade primary school pupils in North Kebily. After a questionnaire, a blood sample was drawn from every child. Hemogram, sickling test, and hemoglobin electrophoresis at alkaline pH were performed for all children. Hemoglobin electrophoresis at acid pH and a specific hemoglobin A2 titration were performed for some children. RESULTS: The study concerned 1,400 children, aged between 5 and 12 years, the mean age was 7 years and 7 months +/- 10 months. Consanguinity rate and coefficient were respectively 44% and 2249 x 10(5). Endogamy was very high. The global rate of hemoglobin abnormalities was 9.4%. Drepanocytosis with a rate of 4.9% was the most frequent, followed by beta thalassemia (3.1%) and C hemoglobinosis (1.6%). These abnormalities were unequally distributed; very frequent in some localities, they were quite absent in others. CONCLUSIONS: This study revealed a hemoglobinosis concentration in Tunisia, which can be classified second after that of Beja in North-western Tunisia. The heterogeneous distribution of the hemoglobin abnormalities in North-Kebili region and the high consanguinity and endogamy rates constitute factors that promote homozygous and double heterozygous forms to arise and justify the elaboration of a preventive strategy.

[Diagnostic and therapeutic aspects of lymphatic tuberculosis: apropos of 42 cases].

We report a retrospective study of 42 cases of lymph node tuberculosis. We noted symptoms of tuberculosis impregnation in 92%, cervical localization in 71%, positive tuberculin intra-dermo-reaction in 77%, and accelerated erythrocyte sedimentation rate in 73% of the cases. Koch bacillus was detected in expectoration, urine or gastric liquid at the rate of 11% of the cases. Lymph node function was suggestive in 4 out of 12 patients, showing giant cells with or without caseum. Lymph node biopsy, performed in 32 patients, was contributive in 94% of them. Another tuberculous localization was found in 14 cases mainly pulmonary (8 cases).

[Fanconi disease: study of 43 cases in southern Tunisia].

BACKGROUND: To report the epidemiologic, clinical, biological features and course of Fanconi's anemia in southern Tunisia. PATIENTS AND METHODS: During a period of 12 years we observed 43 cases. For each patient, careful clinical, biological (hemogram, myelogram, bone marrow biopsy, hemoglobin electrophoresis, karyotype) and radiological (skeleton X-rays, abdominal echography and intravenous urography) examinations were performed. All the patients who were at a pancytopenia stage were given androgens. None had a bone marrow allograft. RESULTS: There were 24 girls and 19 boys. The mean age at diagnosis was 10 years and 9 months. The familial character was present in 53% of the cases. The most frequent initial complaint was anemic syndrome (69%). In ten cases (24%), the diagnosis has been established during a familial investigation. Malformations were present in all cases (abnormal pigmentation: 86%; skeletal maturation retardation: 83%; facial dysmorphy: 76%; statural hypotrophy: 65%; bone abnormalities: 53%; renal malformations: 44%). Anemia was present in 88% of the cases, thrombocytopenia and neutropenia in all cases. Bone marrow was hypoplastic or aplastic in all cases on biopsies. Spontaneous chromosomal breaks were found in 79% of the studied cases. Fetal hemoglobin was increased in 80% of the studied cases with a mean level of 20.5%. Actuarial survival rate at 5 years was 48%, but long survival durations were rare (eight out of 43 patients). DISCUSSION: This disease, rare in the world, seems to be frequent in southern Tunisia. A normal karyotype (with classical techniques), found in five patients, could not discard the diagnosis; for this reason, the use of sensitizing agents should improve the sensitivity of the test. Besides, an increased level of fetal hemoglobin enabled us to suggest the diagnosis in some cases. Androgenotherapy increased the survival duration to more than 5 years in eight patients. However, bone marrow allograft remains the only possibility of cure.

[Hemoglobin beta S haplotype in the Kebili region (southern Tunisia)].

Sickle cell anemia is a monogenic hereditary disease characterized by a mutation in the beta globin gene. Five major haplotypes associated with the beta S mutation have been defined: Benin, Bantu, Senegalian, Camerounian, and Arabo-Indian. Previous studies in northern Tunisia showed that sickle cell anemia was of Benin origin in this region. Patients from the south of Tunisia, mainly from the Kebili region, were not previously concerned. In this study, we have determined the beta S haplotype and evaluated phenotypical expression of the disease in 14 patients from this latter region. The use of four restriction endonucleases having polymorphic sites in the beta globin gene showed that all patients had the Benin haplotype, confirming the Benin origin of sickle cell anemia in Tunisia. This haplotype is associated with an heterogeneous expression of fetal hemoglobin (HbF) with extremes varying from 2.4 to 16.3% and a mean expression rate of 8.16%, which is in accordance with literature data. In spite of the haplotype homogeneity in our patients, clinical heterogeneity was noted. A unique case of alpha-thalassemia could not explain this heterogeneity. In contrast, we found a certain correlation between fetal hemoglobin expression and clinical severity.

[Evaluation of tumoral and lymph node response to neoadjuvant chemotherapy in undifferentiated nasopharyngeal carcinoma].

Between January 1994 and June 1995, 19 cases of nasopharyngeal carcinoma, classified N2-N3 (AJC/UICC 1987) were treated by neoadjuvant chemotherapy including cisplatin 100 mg/m2 on day 1 and epirubicin 80 mg/m2 on day 1. Following course started on day 21. A clinical and scannographic evaluation was made after 3 courses of chemotherapy. Fifty-eight percent of the patients were N3. Seventy-four percent were T3-T4. Tolerance to chemotherapy was good in 100% of the cases. A functional improvement was obtained in 14 among 16 patients who were initially symptomatic. For lymph nodes, an objective response (OR) was observed in all patients. The response was complete (CR) in 53%. A regression of primary tumor was obtained in 68% of the patients, but it was complete in 16% only. Sixty-nine percent of the patients has have a tumoral OR have a lymph node CR. Ninety percent of the patients with a complete lymph node response have a tumoral regression more than 50%. A correlation seems likely between the importance of the tumoral and the lymph node responses.

[Low dose cytarabine in the treatment of acute myeloid leukemia. Apropos of 41 cases].

This is a retrospective study on the use of cytarabine at low doses in acute myeloid leukemias in 41 patients. Four groups of AML are included: group A: 19 cases of de novo AML in elderly patients; group B: ten cases of AML in relapse; group C: five cases of AML refractory to previous treatment and group D: seven cases of secondary AML. Cytarabine was given subcutaneously at the dose of 10 mg/m2 of body surface, for 21 days per month for the first course; then 15 days per month for the following courses. The response rates were 42, 20, 0, and 43% respectively for the A, B, C, and D groups. A complete remission was attained in only 15% (six patients). Extra haematological tolerance was excellent. Infection complications were noted in 66%, whereas a severe neutropenia was observed in 34% of patients. Hemorrhagic complications were more rare (20% of patients). The mean duration of complete remission was 10 months. The median survival was 10.5 months (2 to 31 months) for the responder patients, and 2.4 months (1 to 7 months) for the non-responders. Cytarabine at low doses seems to be a good indication for first intention treatment of AML in elderly patients. It does not give a bone marrow aplasia, the infection and hemorrhagic episodes are less numerous than with conventional dose chemotherapy, the life quality is improved, and treatment at home is often possible.
