Amyloid arthropathy revealed by RS3PE syndrome.

Amyloid arthropathy is a form of primary AL amyloidosis with a monoclonal component in the blood and/or urine, and RS3PE syndrome is acute edematous polysynovitis in subjects older than 60 years. A 74-year-old man was diagnosed with both disorders. He was admitted for benign acute polyarthritis of the hands and feet and reported carpal tunnel symptoms predominating on the right. A synovial biopsy at the right wrist disclosed deposits that stained with Congo red even after potassium permanganate treatment (positive Wright's test). Articular AL amyloidosis was diagnosed. The symptoms resolved under glucocorticoid therapy alone, casting some doubt on their relationship with the amyloidosis. Roentgenograms showed geodes, a feature not present in RS3PE. Whether RS3PE may be among the possible presentations of articular amyloidosis is discussed.

HLA-DRB1 alleles and shared amino acid sequences in disease susceptibility and severity in patients from eastern France with rheumatoid arthritis.

OBJECTIVE: To examine the effects of HLA-DRB1 alleles and amino acid sequences that carry the shared epitope (SE) upon rheumatoid arthritis (RA) susceptibility and disease severity in patients from Eastern France. METHODS: HLA-DRB1 alleles were determined in 120 patients and 104 healthy controls by polymerase chain reaction/sequence specific oligonucleotide probes. Subtyping of DRB1*01 and *04 were performed using sequence specific primers. Patients were retrospectively evaluated for disease duration, age at disease onset, presence of rheumatoid factors, subcutaneous nodules, vasculitis and other extraarticular diseases, for the need for arthroplasty and immunosuppressive/immunoregulatory agents, and for radiographic damage. RESULTS: The prevalence of HLA-DRB1*04 was significantly higher in patients (46.6%) than in controls (17.3%) (Pcorr = 0.000003). HLA-DRB1*0101 and *0401 were the most prominently associated subtypes in patients with RA (33.3%, Pcorr = 0.011, and 28.3%, Pcorr = 0.00008, respectively). A significant fraction of patients (72.5%) expressed one or 2 copies of the SE (p < 0.0000001; OR 4.77, CI 2.61-8.78). The presence of double SE was associated with a higher risk of developing RA (OR 4.83, CI 1.91-12.71; p = 0.0001). No significant differences in the clinical records among patients expressing no RA linked alleles, one and 2 copies of the SE, were observed. However, analyzing the specific effect of each amino acid sequence, we observed a significant association of the QKRAA motif with vasculitis (p = 0.03) and history of joint replacement surgery (p = 0.05), suggesting a role for lysine in position 71 of the shared sequence. CONCLUSION: These findings differ from those of previous HLA-DRB1 allele studies in patients with RA from other regions of France. Thus, the heterogeneity in both the expression of DRB1 alleles and the association of these alleles with disease severity could be relevant within a country such as France.

Pneumococcal polyarticular septic arthritis in a patient with rheumatoid arthritis.

Rheumatoid arthritis is the most commonly reported host-related risk factor for septic arthritis. This risk is highest in severe, seropositive, long-standing (mean, 10 years) rheumatoid arthritis responsible for extraarticular symptoms and treated with systemic glucocorticoids. The clinical presentation of the joint infection is often atypical, leading to diagnostic wanderings. In 25% of cases, the infection is polyarticular, with 3.5 involved joints on average. Staphylococcus aureus is the most common causative organism. Streptococcus pneumoniae causes 5% of all cases of septic arthritis and is more often responsible for polyarticular infections than other organisms. Polyarticular septic arthritis carries a poor prognosis, with a mortality rate of 50% in rheumatoid arthritis patients. Despite its low incidence, polyarticular septic arthritis should be routinely considered in the differential diagnosis of rheumatoid flares. We report a case of pneumococcal septic arthritis involving five joints in a patient with known rheumatoid arthritis. Three other cases with involvement of more than four joints have been published.

[Cuniculatum carcinoma. 6 cases and review of the literature].

The cuniculatum carcinoma is a rare type of epidermoid carcinoma. We report 6 cases with different localizations ("oral cavity and larynx", vulva, lower limb) treated over a 23-year period. Diagnosis is particularly difficult and requires careful clinical examination completed by deep surgical biopsy for histology. The aetiology of the tumour is not well defined. It presents as a slow growing wart with local malignancy and chronic suppuration. Extension to lymph nodes is rare. Histologically there is proliferative deep malpighian infiltration with an aspect of normal cell maturation. Galeries are hollowed out giving the aspect of a rabbit burrow (cuniculatum). Surgery is the only treatment, generally without lymph node curage. Radiotherapy is contraindicated due to anaplastic transformation.

[Insular carcinoma of the thyroid. Apropos of a case and review of the literature].

We present a new case report of "Insular" thyroid carcinoma. The first series was published, in 1984, by Carcangiu et al. The propensity for local recurrence and early distant metastases explains the poor prognosis of this carcinoma and demands aggressive therapy at the time of diagnosis. This includes radical surgery, radiotherapy with possible chemotherapy. Clinical and pathological arguments suggest that this carcinoma could be an intermediate stage in the process of loss of differentiation of some thyroid neoplasms.

[Malignant hemangioendothelioma of the thyroid. Pathologic study of a case].

The authors report a case of malignant tumor of the thyroid in a 79 years old woman with a long standing goiter for 20 years but who did not live in endemic mountainous goiter area. The right lobe of the thyroid was surgically removed in February 1992 because increasing in size. Pathologic diagnosis was non malignant cystic lesion. Two months later, a recurrence with dyspnea urged a tracheostomy. The patient died 9 days later because of intra bronchial and pleura hemorrhage. The morphological and immuno-histochemical investigations showed angiosarcomatous features and positive reactivity with Factor VIII and UEA 1 markers in the tumour and pulmonary metastases. The diagnosis of Malignant hemangio-endothelioma was concluded.

[Primary and secondary carcinomas of the thyroid gland with systematic discovery. Apropos of hundred thyroid glands removed at autopsies and review of the literature].

One hundred thyroids from autopsies performed in a Cancer Center were sectioned at 4 mm intervals. Each slice was processed to obtain one or several sections for histologic examination. Five primary microcarcinomas and ten secondary clinically unknown carcinomas were found. This study and the review of the literature confirm that the high prevalence rate of microcarcinomas, most of them papillary, in autopsies does not agree with the clinically diagnosed carcinoma rate. Tumors greater than 5 mm in diameter may sometimes be aggressive. Intrathyroid metastases are relatively frequent in cancerous dissemination observed in autopsies, but raise problems when they precede the primary tumor or are revealed on surgical samples a long time after because of a slow development. The authors emphasize the importance of differential diagnosis between primary and secondary tumors and the value of immunohistochemistry for histological diagnosis.

[The value of peritoneal cytology in invasive uterine cancers. Analysis of 80 cases].

When they analysed 80 cancers of the uterus, the authors showed how valuable it was both for diagnosis and prognosis to carry out cytological lavage of the peritoneum, particularly in cases of endometrial adenocarcinoma. The results of this study are compared with recent extracts appearing in the international literature. This technique makes it possible to identify groups of patients of high risk for recurrences in the pelvis and abdomen who would benefit from adjuvant therapies, demonstrating that this technique is applicable to the diagnosis of gynaecological cancers with intraperitoneal spread which have long been failed to be recognised. The procedure is innocuous and simple and therefore should be carried out widely in the management of uterine cancers.

[Extra-skeletal Ewing's sarcoma. A case report with detailed review of the literature].

Extra-skeletal Ewing's Sarcoma (EES): a clinico-pathological entity described in 1975 by L. Angervall and F.M. Enzinger. This article reports a new case in which the primary was localized in the right forearm and metastasized to the left lung fourteen years later. A detailed review of the literature emphasized similarities and differences between osseous and extra-osseous Ewing's Sarcoma.

[Gastric teratoma in newborn children].

In neonates, teratomas infrequently involve the abdomen: among 51 known cases, 39 were gastric teratomas, which account for less than 2% of all germ cell tumors in the neonatal period. Associated malformations are minor, located in the region of the tumor, and apparently less frequent than in other sites. Malignancy is exceedingly rare (a single case) and well controlled as a result of the anti-tumor processes specific to the neonatal period. Gastric teratomas are diagnosed early and can be cured by tumorectomy removing a thin ring of the surrounding stomach wall.

[Influence of vancomycin by venous route on salivary and fecal aerobic floras].

An IV vancomycin treatment induces a reduction of Gram positive cocci (Staphylococcus, Enterococcus) of the aerobic salivary and fecal flora. Some of these strains persisted during and after treatment, but remained susceptible to vancomycin. Others isolated Gram positive cocci were resistant to vancomycin before and after treatment. They were identified as Pediococcus sp., and Leuconostoc sp. There is a reduction of the number of Gram positive cocci, without increase of Gram negative rods, Lactobacillus, or Candida which are always resistant to vancomycin.

[Identification and rapid determination of the antibiotic resistance of enterobacteria with the automated ABAC identibiogram].

Rapid identification and antimicrobial testing of Enterobacteriaceae by an automated system, the ABAC-Identibiogramme. The system was directly inoculated with a dilution of positive blood culture broths. The results were compared with those of API 20E and the disk method for antibiogram. The ratios of agreement of 94.5% for identification and of 93.4% for antimicrobial testing demonstrate a good accuracy of the ABAC-Identibiogramme.

[Human salmonellosis in Ille-et-Vilaine in 1983].

224 salmonella strains from human beings, collected by the public and private laboratories of Ille-et-Vilaine during 1983, were serotyped and tested for their susceptibility to antibiotics. Salmonella typhimurium infections were the most frequent, while the other serotypes constituted a small number of strains, generally susceptible to antibiotics. No outbreak due to a multi-resistant serotype was observed. S. typhi and S. paratyphi B represent 6,25% of the strains isolated in this area during the year. Only 22% of the 224 strains collected were resistant to one or more antibiotics.
