A Prospective Study of the Outcome of Patients with Limb Trauma following the Haitian Earthquake in 2010 at One- and Two- Year (The SuTra2 Study).

Background Severe limb trauma is common in earthquake survivors. Overall medium term outcomes and patient-perceived outcomes are poorly documented. Methods and Findings The prospective study SuTra2 assessed the functional and socio-economic status of a cohort of patients undergoing surgery for limb injury resulting in amputation (A) or limb preservation (LP) one year and two years after the 2010 Haiti earthquake.

delta Ef1 binds to a far upstream sequence of the mouse pro-alpha 1(I) collagen gene and represses its expression in osteoblasts.

The transcription of type I collagen genes is tightly regulated, but few cis-acting elements have been identified that can modulate the levels of expression of these genes. Generation of transgenic mice harboring various segments of the mouse pro-alpha1(I) collagen promoter led us to suspect that a repressor element was located between -10.5 and -17 kilobase pairs.

Matrix metalloproteinase 9 protects mice from anti-glomerular basement membrane nephritis through its fibrinolytic activity.

Matrix metalloproteinase (MMP)9/gelatinase B is increased in various nephropathies. To investigate its role, we used a genetic approach. Adult MMP9-deficient (MMP9(-/)-) mice showed normal renal histology and function at 3 mo.

[Long-term survival and prognostic factors in stage II-III multiple myeloma treated with conventional chemotherapy].

In this retrospective study, survival and prognostic factors were analysed in 65 patients with stage II-III multiple myeloma with osteolytic lesions. Multiple myeloma was diagnosed from 1976 to 1984, and patients were treated with conventional chemotherapy. The response rate to initial chemotherapy was 46%.

Distribution of enkephalinase (membrane metalloendopeptidase, E.C. 3.4.24.11) in rat organs. Detection using a monoclonal antibody.

A monoclonal antibody to enkephalinase (membrane metalloendopeptidase E.C. 3.

[Polyneuropathy and solitary bone plasmacytoma. A new case].

The authors report a case of acute polyneuropathy revealing a solitary osseous plasmacytoma with osteo-dense and osteolytic bone lesions. Initially, the rapid progression of the sensory and motor loss led to treatment by plasma exchanges and irradiation of the plasmacytoma. Four months later, despite a significant improvement of the neurological condition, serum protein electrophoresis continued to show a peak of monoclonal immunoglobulin.

[Twenty-three cases of gonococcal arthritis (author's transl)].

Twenty-three cases of gonococcal arthritis involving 10 men and 13 women aged from 18-81 years (mean, 32 years) are reported. Seven of the men had developed urethritis 3 to 21 days previously. Seven of the women had no signs or symptoms of genital infection.

Peripheral neuropathy and plasma cell neoplasias: a report of 10 cases.

Ten patients with peripheral polyneuropathy associated with plasma cell neoplasias are reported. Progressive sensorimotor polyneuropathy was the presenting complaint in all patients. CSF protein concentration was elevated in most patients.

[Polyradiculoneuritis associated with plasmocytoma. Recovery following radiotherapy (author's transl)].

A new case of extensive subacute polyradiculoneuritis associated with a costal plasmocytoma secreting IgG lambda is reported. Radiotherapy of the rib, resulted in remarkable neurological improvement and haematological cure, which have now persisted for more than 5 years, though treatment was discontinued 3 years ago. By its distinctive haematological features, this case illustrates the lack of clear-cut distinction between "solitary" plasmocytoma and multiple myeloma.

[Vascular and obstetrical prognosis after hypertension during pregnancy: value of renal biopsy (author's transl)].

Renal biopsy was performed in 125 patients with severe hypertension during pregnancy. Three groups could be defined: I: normal kidney; II: vascular lesions; III: nephropathy. The histological appearance could not be suspected from clinical criteria (age, parity, symptoms, date of appearance).

Delay in growth and the development of nephritis in rats treated with interferon preparations in the neonatal period.

Suckling rats were injected for 14 to 17 days with potent rat-cell-culture interferon preparations or various heterologous interferon or control preparations. Only treatment with rat interferon resulted in a delay in growth and maturation of different organs and the subsequent development of an "immune complex" type nephritis. Thus, 38 of 43 rats treated with rat interferon developed a severe glomerulonephritis.

Glomerular fibrinolytic activity during nephrotoxic nephritis.

The glomerular fibrinolytic activity (GFA) was measured during the development of glomerulonephritis induced by the intravenous injection of horse or rabbit antiglomerular basement membrane antibodies in rats either untreated or preimmunized with horse or rabbit Ig. A variety of nephritides was produced ranging from proteinuria with no or mild changes in glomerular architecture to severe diffuse proliferative glomerulonephritis with close to 100% crescent formation. GFA was measured on preparations of isolated glomeruli using a radioassay based on lysis of 125I fibrin adsorbed on a solid phase.

[Diagnostic value of synovial membrane immunofluorescence].

The immunofluorescent study of 93 synovial membranes of persons suffering from various types of arthropathy has shown that the only element sufficiently specific to have real diagnostic value is the presence of cells with a fluorescent cytoplasm. This appearance was in fact found in 63% of the cases of rheumatoid arthritis, irrespective of their being either seropositive or seronegative, in 69% of the cases of probable rheumatoid arthritis, in only 15% of the unclassified cases of arthritis, in 28% of the cases of various types of arthritis (20% with exclusion of a case of mixed connectivitis and of a case of Waldenström's macroglobulinemia with rheumatoid arthritis) and in 0% of the cases of mechanical arthropathy. The results of immunofluorescent examination compare favorably with those of standard histology: the classical histologic appearance of rheumatoid synovitis with a node-forming tendency of the infiltrate was observed in only 36% of the verified cases of rheumatoid arthritis, while immunofluorescence was positive in 63% of the cases in this group.
