[Imaging of the postoperative knee in athletes: articular cartilage, menisci, and ligaments]. / Imagerie du genou du sportif opéré: cartilage, ménisques et ligaments.

This article focuses on the common surgical procedures and reviews the clinical and imaging features of the postoperative knee following prior surgical treatment of meniscal, articular cartilage, and ligamentous injuries.

[Treatment of chronic postinfectious fatigue: randomized double-blind study of two doses of sulbutiamine (400-600 mg/day) versus placebo]. / Traitement de l'asthénie en période postinfectieuse: étude randomisée en double aveugle de deux doses de sulbutiamine (400-600 mg/j) versus placebo.

PURPOSE: Chronic fatigue remains a medical mystery and a therapeutic failure. The subgroup of chronic fatigue postinfectious fatigue (CPIF) is an interesting one since it is quite frequent in general practice. METHODS: We studied sulbutiamine (Su), isobutyryl-thiamine disulfide in this context. We included 326 general-practice patients suffering from CPIF: they received randomly either Su, 400 mg daily (n = 106), or Su, 600 mg daily (n = 111), or placebo (n = 109) for 28 days in a double-blind, parallel-group study. 315 patients completed the study. RESULTS: The evaluation of fatigue, by multiple means including mainly MFI, a validated multidimensional fatigue scale, showed overall no significant difference between the groups. On the 7th day, however, women receiving Su, 600 mg had less fatigue (P < 0.01), but the figures were quite diverse and no persistent effect was noted at the 28th day. CONCLUSION: Thus, we showed for the first time that a high level general-practice study of fatigue is feasible using specific tools. Whether the effect observed after 1 week in women represents a true finding needs additional research. Further studies are in progress in order to characterize better the potential usefulness of Su in chronic fatigue.

[A paraneoplastic acrosyndrome]. / Un acrosyndrome paranéoplasique.

BACKGROUND: Paraneoplastic digital ischemia is an uncommon complication of metastatic adenocarcinomas. CASE REPORT: Two years after remission of an uterine adenocarcinoma, the patient developed an acrosyndrome involving all four limbs with digital ischemia. Recurrent carcinoma was evidenced by a very high antinuclear antibody titer. Chemotherapy improved the acrosyndrome. DISCUSSION: Vasomotor disorders which developed in older subjects with no other signs of autoimmune disorders should suggest a neoplastic origin. Icshemia of the fingers would be caused by vasculitis. An elevated antinuclear antibody titer may be a supplementary argument suggesting a neoplastic etiology.

[Access to social coverage of uninsured patients attending a hospital clinic: a historical cohort study at the Baudelaire outpatient clinic in Paris]. / Accès à une couverture sociale des patients non assurés consultant en milieu hospitalier: une étude de cohorte historique au sein de la consultation "Baudelaire" à Paris.

BACKGROUND: In France health insurance coverage is universal (see note at the end of the text), nevertheless some people remain uninsured. In this high-risk population, the lack of insurance coverage contributes to the aggravation of health, by reducing access to medical care. In 1992, the Baudelaire consultation was incorporated into the outpatient clinic of Saint-Antoine hospital (Paris, France), to provide the uninsured with the same access as any other patient--but free of charge--to medical care. Social care was also provided in particular by assisting the uninsured in applying for insurance coverage. Our objectives were to quantify the delay in obtaining insurance coverage and to study whether the sociodemographic characteristics of these patients were associated with inequalities in terms of delays. METHODS: All patients attending the consultation for the first time in 1994 were included (n = 623). Because of differences linked to the French social security system, analysis was performed into two groups according to the existence of a prior insurance coverage. Delay in obtaining or recovering insurance coverage was considered as the key variable. The socio-demographic factors linked to the rates of access to insurance coverage were determined using Cox proportional hazards regression models. We also examined the factors linked with the existence of a prior insurance coverage by logistic regression modeling. RESULTS: Within one year 96% of the patients who had had insurance coverage in the past, and 63% of the patients who had not, were insured. No factor, whether nationality, educational level, socio-professional category, family situation, type of housing, made of income was found to be linked with obtaining or recovering insurance coverage. However, nearly all these factors were related with the existence of prior insurance coverage. CONCLUSIONS: Our approach of systematically providing social care allows 70% of uninsured patients to obtain insurance coverage within one year. This approach probably contributes to an improvement by facilitating access to mainstream health care. Moreover, no difference in delay in obtaining insurance coverage was found associated with sociodemographic characteristics.

[Mixed corticomedullary tumor]. / Tumeur mixte corticomédullaire.

BACKGROUND: Pheochromocytoma and primary hyperaldosteronism rarely occur simultaneously. Few cases have been reported in the literature. CASE REPORT: A patient explored for hypertension was found to have hypokalemia related to primary hyperaldosteronism. Pathology examination of the ablated adrenal showed a co-existing pheochromocytoma suspected at history taking although urine catecholamines were normal. DISCUSSION: Different pathogenic hypothesis have been proposed. Such dual tumors could be a simple coincidence, occur in a particular genetic setting, be related to direct contact between cortical and medullary tissue leading to reactional cortical hyperplasia, pheochromocytoma produced factors stimulating aldosterone synthesis, or factor X, a substance produced by cortical adenomas and favoring growth of the pheochromocytoma.

A new out-patient care facility for HIV-infected destitute populations in Paris, France.

In France, the entire population theoretically has access to health coverage, but in fact a section of the poorest population does not. Institutions have therefore been set up to provide medical care for the destitute. The objectives of this study were to describe the social characteristics of the HIV-positive destitute population attending an out-patient clinic providing free health care for the destitute in a Paris University Hospital, to compare their clinical-epidemiological characteristics with those of non-destitute HIV-positive patients, and to evaluate the quality of their care. We performed a historical prospective study wherein a cohort of 115 HIV-positive destitute patients (defined as having no health coverage at their first consultation) was compared with a control cohort of 183 HIV-positive non-destitute patients attending the same clinic. Ninety-five per cent of the destitute patients had no stable employment, 32% had no source of income, 75% had no permanent residence and 27% were i.v. drug abusers. Fifty-nine per cent were foreigners, most of whom had legal residence papers and had been in France for more than 3 years. When comparing the control and the destitute groups, the latter had a three times greater risk of developing tuberculosis (RH = 3.2, CI 95% = [1.1-9.4]). Medical compliance, access to antiretroviral treatment and hospitalization were identical in both groups. No difference was observed in terms of occurrence of a new AIDS-related disease during follow-up when full-blown AIDS before entry, CD4 count at entry and transmission group were taken into account in multivariate analysis. From the moment that destitute patients attended this adapted medico-social facility, their access to care was the same as, if not better than, that of the other patients. The development of out-patient medico-social facilities for HIV-positive destitute patients must be a public health priority even for those countries theoretically providing generalized health coverage.

Cerebral infarction associated with vasculitis due to varicella zoster virus in patients infected with the human immunodeficiency virus.

Cases of herpes zoster ophtalmicus (HZO) with delayed contralateral hemiparesis caused by hemispheric stroke secondary to granulomatous angiitis have been reported and are a well-recognized complication of herpes zoster. Similar cases have been reported more recently during infection with human immunodeficiency virus (HIV). We describe two HIV+ patients without any clinical history of zoster dermatitis who developed a sudden hemiparesis followed 2 weeks later for one by an acute retinal necrosis. Computerized tomography (CT) scan, magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), and digital subtraction angiography (DSA) were performed and showed a hemispheric stroke with evidence of a segmental arteritis of the carotid syphon. Varicella zoster virus (VZV) was found in the cerebro spinal fluid (CSF) in the two patients and after puncture of the vitreous fluid of the patient with the acute retinal necrosis. These two cases exemplify the difficulty of diagnosis of stroke in HIV+ patients, which seems to be more frequent than in similarly aged non-infected patients and demonstrates that VZV needs to be taken in consideration and identified even without any past history of zoster dermatitis.

Solitary fibrous tumor of the adrenal gland.

Solitary fibrous tumors are rare neoplasms, most commonly involving the pleura, recently described in various other locations. We report a solitary fibrous tumor of the right adrenal gland in a 42-year-old woman, discovered incidentally during abdominopelvic ultrasonographic examination. Pathologic and immunohistologic features of the tumor were identical to those of other solitary fibrous tumors. Three-quarters of this unencapsulated infiltrating tumoral mass presented foci of hemorrhage and were made of small, round, epithelioid-like cells that expressed the CD34 antigen more weakly than do the typical spindle cells usually observed in solitary fibrous tumors. Despite hemorrhage and poor limitation, the tumor behaved in a innocuous manner; the mass remaining unchanged for more than 5 years before the patient agreed to surgical intervention, which was recommended because of a sudden enlargement of the mass.

[Severe contact dermatitis caused by mephenesin]. / Dermite de contact grave à la méphénésine.

INTRODUCTION: Mephenesin is a muscle relaxant, mostly applied locally in trauma. It is a component of Traumalgyl cream in association with phenylbutazone. Contact dermatitis due to mephenesin is exceptional. CASE REPORT: We report here a case of a woman who developed after application of Traumalgyl cream purpuric dermatitis, erythema multiforme-like and urticarial lesions. Patch-tests were strongly positive (+ + +) for both Traumalgyl cream and mephenesin and (+) for phenylbutazone. Improvement of the lesions was observed within 3 weeks. DISCUSSION: Physicians must be aware of the risk of severe contact dermatitis after application of products including mephenesin because of their widely prescription.

Changes in systemic gonadal and adrenal steroids in asymptomatic human immunodeficiency virus-infected men: relationship with the CD4 cell counts.

Serum sex hormone-binding globulin (SHBG), testosterone, non-SHBG-bound testosterone, androstenedione, dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and cortisol were measured in 58 homosexual men seropositive for human immunodeficiency virus (HIV), all clinically asymptomatic (Centers for Disease Control 1993 classification stage A). The HIV patients were divided into four groups according to the CD4 lymphocyte count--group 1 (more than 500/microliters, N = 14), group 2 (between 350 and 500/microliters, N = 16), group 3 (between 200 and 349/microliters, N = 22) and group 4 (less than 200/microliters, N = 6)--and compared with 11 antibody-negative men as controls. The SHBG levels were significantly increased in groups 1, 2, 3 (p < 0.01) and 4 (p < 0.05) compared with controls, with no differences between groups of patients. Compared with controls, testosterone concentrations were significantly lower in group 4 (p < 0.05) and non-SHBG-bound testosterone levels were significantly lower in groups 1 (p < 0.05), 2 (p < 0.01), 3 (p < 0.001) and group 4 (p < 0.001); DHT and androstenedione levels were significantly lower in group 4 (p < 0.05) and DHEA levels were significantly lower in group 2, group 3 (p < 0.01) and group 4 (p < 0.05) than in controls. Cortisol levels were significantly increased in groups 1 and 4 (p < 0.05) and FSH and LH concentrations were not significantly higher in HIV-infected men than in controls. Also, the DHEA, androstenedione, non-SHBG-bound testosterone and DHT levels were correlated with CD4 cell counts, showing that hypogonadism occurs as the CD4 lymphocytes decrease.(ABSTRACT TRUNCATED AT 250 WORDS)

[Primary Gougerot-Sjogren syndrome. Spontaneous one-year course of clinical, biological and histological signs]. / Syndrome de Gougerot-Sjögren primaire. Evolution spontanée sur un an des signes cliniques, biologiques et histologiques.

OBJECTIVES: The natural clinical course of primary Sjögren's syndrome was followed in 8 patients to identify the concomitant functional, clinical, biological, scintigraphic and histological manifestations of the disease. METHODS: The diagnosis of primary Sjögren's syndrome was made on the basis of functional signs (ocular or salivary sicca syndrome) and 2 positive tests among the 3 objective ocular tests (Schirmer's test, break-up time, Rose Bengale). Work-up included recording of functional and clinical signs, ophthalmologic examination and laboratory tests at diagnosis and every 3 months for 12 months. Scintigraphy of the salivary glands was performed together with a biopsy at diagnosis and at 12 months. RESULTS: No one parameter varied significantly over a 1 year period demonstrating the lack of need for renewed examinations for diagnosis or regular follow-up. CONCLUSION: This is the first report providing a homogeneous series studied by one team over a determined period of time. It demonstrates that clinical, biological and anatomic criteria for primary Sjögren's syndrome do not show any correlation between functional signs and objective ocular tests.

[Treatment of Still disease in adults with intravenous immunoglobulins]. / Traitement de la maladie de Still de l'adulte par immunoglobulines intraveineuses.

In most cases, the treatment of adult's Still disease presents difficulties, in view of its undesirable side-effects. For this reason, we made an open trial of the effects of high-dose intravenous immunoglobulins (IVIg), a therapy with low iatrogen risk, and whose effectiveness in the treatment of other multisystemic diseases has been acknowledged. Seven patients suffering from adult Still's disease were given between one and eight IVIg infusions with a dose of 1 g/kg/day for two consecutive days. All seven responded positively, with clinical improvement. It lasted between 1 and 90 days in three patients, who subsequently relapsed; it has been continuing for an average of 13 months (2 to 24 months) in the other four patients. There were no clinical features making it possible to distinguish, after the trial, the patients who responded positively to intravenous immunoglobulins. This data, which needs to be confirmed with a controlled trial, provides hope of improved therapy for the one half of patients suffering from adult Still's disease who respond positively to intravenous immunoglobulins.

[Disseminated intravascular coagulation associated with prostatic cancer]. / Coagulation intravasculaire disséminée associée au cancer de la prostate.

Disseminated intravascular coagulation (DIC) associated with prostate adenocarcinoma is a bad prognostic sign. Most of the cases are limited to biological abnormalities. Some, however, come to medical attention due to thromboembolic or hemorrhagic complications. We report 4 such cases and review the pertinent literature. The characteristic features are low platelets and coagulation factors in an elderly man. In two out of the four cases, bleeding due to the DIC revealed the cancer. All patients received hormonotherapy and heparin. The worst fate (case 3) was a subacute one with no effect of the drugs and death in a short time. The other cases went into a five- to seven months remission before uncontrollable bleeding led to death. No favorable effect of the chemotherapy was observed. Thus, new treatments are sought for this rare but ominous complication of prostate cancer.

[Association of Gougerot-Sjögren syndrome and viral hepatitis C. Apropos of 6 cases]. / Association d'un syndrome de Gougerot-Sjögren et d'une hépatite virale C. A propos de 6 observations.

Hepatitis C virus (HCV) has been found in the serum of 3 out of 109 patients with Sjögren's syndrome, whereas Sjögren's syndrome has been demonstrated in 3 out of 7 HCV-positive patients. The six HCV-positive Sjögren's syndrome patients were compared with 95 HCV-negative Sjögren's syndrome patients. Anti-smooth muscle antibodies were detected in 1 of the former group and 6 of the latter. Cryoglobulin existed in 1 and 6, respectively. The levels of circulating IgA and IgA-containing immune complexes were lower in the HCV-positive than in the HCV-negative patients.

[Risk of nosocomial Pneumocystis carinii pneumonia in immunosuppressed patients non-infected by human immunodeficiency viruses]. / Le risque de pneumocystose nosocomiale chez les immunodéprimés non infectés par le virus de l'immunodéficience humaine (VIH).

We report four cases of Pneumocystis carinii pneumonia (PCP) in Human Immunodeficiency Virus (HIV)-seronegative patients. Two of them had been hospitalized for polymyositis treatment near AIDS patients, respectively 1 and 4 months before PCP. The two others suffered from localized cancer. Their evolution was complicated by respiratory distress and death in two of them. A telephone survey among 19 hospital units yielded nine cases of similar patients. They were only observed in wards caring for AIDS patients at the same time, thus raising the question of a possible nosocomial transmission of PCP between AIDS patients and immunocompromised HIV-seronegative patients. This adds to the growing concern for hospital-acquired infections, including resistant tuberculosis and other opportunistic pathogens. We propose some practical measures to limit this risk by simple means such as no-contact between at-risk populations, enhanced disinfection procedures of the rooms and masking of the coughing PCP patients.

[Specific respiratory manifestations of Horton disease]. / Les manifestations respiratoires spécifiques de la maladie de Horton.

Several respiratory manifestations have been described in patients with temporal arteritis. These complications may develop at the onset of the disease or later. Cough is the most frequent of them. Other complications include pleural effusions, interstitial pneumonitis, pulmonary vasculitis. Hyperreactive airways, hoarseness, diaphragm paralysis have been noted. Generally, corticosteroids cause a prompt improvement. Physicians should be aware of respiratory symptoms in patients with temporal arteritis in order to avoid delays in diagnosis and therapy.
