ABSTRACT

Septic arthritis of the pubic symphysis is uncommon, and usually occurs in patients with predisposing conditions (female incontinence surgery, sports). Staphylococcus aureus and Pseudomonas aeruginosa are the main bacteria responsible of these infections. Streptococcal infections of the pubic symphysis are uncommon. We report three cases of streptococcal infections of the pubic symphysis that occurred in the absence of predisposing condition such as surgery or endocarditis. The diagnosis of septic arthritis was difficult, particularly in one patient who underwent an orchidopexy for a suspected of spermatic cord torsion before diagnosis was corrected. All three patients had a favourable outcome after an antibiotic treatment combining amoxicillin and rifampicin. Septic arthritis of the pubic symphysis should be suspected in patients with sudden groin pain, pubic tenderness and fever to avoid traumatic treatments and useless investigations.

ABSTRACT

The hypereosinophilic syndromes (HES), defined by an unexplained and sustained hypereosinophilia, can be associated with heterogeneous hematological conditions. Several molecular mechanisms underlying the eosinophilia, which remained indeterminate for a long time, have been recently identified. These recent advances allowed a better classification of the various forms of HES and the development of targeted therapies. The role of tyrosine kinases, especially PDGFRA, and the efficacy of tyrosine kinases inhibitors dramatically improved the diagnosis and the treatment of myeloproliferative variant of HES. On the other side, eosinophilia can be driven by IL-5 secreting abnormal and often clonal T cell subsets (lymphocytic variant of HES). The crucial role of this cytokine in eosinophil development, activation and survival leads to the assessment of anti-IL-5 monoclonal antibodies which have recently shown to provide a significant corticosteroid sparing effect in FIP1L1-PDGFRA negative HES patients. Despite these major advances, half of HES remains unexplained (idiopathic HES). Some FIPL1-PDGFRA negative patients respond to imatinib, suggesting the role of other tyrosine kinases (or other partners than FIP1L1 in a fusion gene implicating PDGFRA). Development of new biomarkers is needed to help physicians in the diagnosis, classification of HES and in the choice of a targeted therapy.

ABSTRACT

Among diagnostic progress over the last three years in internal medicine, Antisynthetase Syndrome is now more easily recognised with the diffusion of laboratory tests for research of antibodies against tRNA synthetases (Anti JO1, anti PL7, Anti PL12). In two third of cases, these antibodies are found despite absence of antinuclear antibodies. Hence, we have to search them specifically in patients with polyarthritis associated with myositis, cutaneous manifestations (Raynaud phenomenom and "mechanic'hands") and interstitial lung disease. Discovery of asymptomatic mutation in the L ferritin coding sequence help us to better understand the "unexplained" hyperferritinemia. Initially described by japonese gastroenterologists, auto immune pancreatitis in fact a part of a systemic sclerosing disease with a biochemical hallmark: in crease of a subclass of immunoglobulins G (IgG4). A new pediatric disease due to a deficiency of the interleukin1 receptor antagonist (multifocal aseptic osteitis, periostitis, stomatitis, disseminated pustulosis) help us to better understand unexplained auto inflammatory diseases. The therapeutic progress is primarily due to an explosion of biological therapies, particularly four of them very useful for internists (in an off label use) : Interleukin 1 inhibitors (anakinra, Canakinumab) to treat some auto inflammatory diseases (cryopirin associated periodic syndromes and deficency of interleukin 1 receptor antagonist), monoclonal antibody against interleukin 5 (mepolizumab) to treat some hypereosinophilic syndromes and Churg and Strauss angiitis, interleukin 6 inhibitiors to treat multifocal Castleman's disease and adult Still disease, a monoclonal antibody against vascular endothelial growth factor (Bevacizumab) to treat hereditary hemorrhagic telangiectasia.

ABSTRACT

INTRODUCTION: Erdheim-Chester disease is a rare non-Langerhans form of histiocytosis. We report the use of combined fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET-CT) in this disease. EXEGESIS: Three men, aged from 55 to 74 years with confirmed Erdheim-Chester disease were included. 18F-FDG PET-CT allowed to detect visceral and vascular involvement of the disease which were overlooked with CT-scan or magnetic resonance imaging: left common carotid and ilio-femoral artery in one patient, coronary, femoral and tibia in the second, aortic, common carotid, femoral and mandibula in the remaining patient. Also, sequential 18F-FDG PET-CT was useful to appreciate treatment efficiency (decrease hyperfixation) and decide treatment modification (interferon alpha). CONCLUSION: 18F-FDG PET-CT combined imaging allows to assess the extent of involvement in Erdheim-Chester disease. 18F-FDG PET-CT may be also a useful tool in the management of Erdheim-Chester disease.

ABSTRACT

Idiopathic hypereosinophilic syndrome (HES) characterized by unexplained and persistent hypereosinophilia is heterogeneous and comprises several entities: a myeloproliferative form where myeloid lineages are involved with the interstitial chromosome 4q12 deletion leading to fusion between FIP1L1 and PDGFRA genes, the latter acquiring increased tyrosine kinase activity. And a lymphocytic variant, where hypereosinophilia is secondary to a primitive T lymphoid disorder demonstrated by the presence of a circulating T-cell clone. We performed molecular characterization of HES in 35 patients with normal karyotype by conventional cytogenetic analysis. TCRgamma gene rearrangements suggesting T clonality were seen in 11 (31%) patients, and FIP1L1-PDGFRA by RT-PCR in six (17%) of 35 patients, who showed no evidence of T-cell clonality. An elevated serum tryptase level was observed in FIP1L1-PDGFRA-positive patients responding to imatinib, whereas serum IL-5 levels were not elevated in T-cell associated hypereosinophilia. Sequencing FIP1L1-PDGFRA revealed scattered breakpoints in FIP1L1-exons (10-13), whereas breakpoints were restricted to exon 12 of PDGFRA. In the 29 patients without FIP1L1-PDGFRA, no activating mutation of PDGFRA/PDGFRB was detected; however; one patient responded to imatinib. FISH analysis of the 4q12 deletion was concordant with FIP1L1-PDGFRA RT-PCR data. Further investigation of the nature of FIP1L1-PDGFRA affected cells will improve the classification of HES.

ABSTRACT

OBJECTIVE: To report our experience on a multicentre series of 32 patients with either typical or atypical Cogan's syndrome, to combine our results with a detailed review of the literature, and to compare the clinical manifestations of typical and atypical Cogan's syndrome. METHODS: Patients were identified from a survey conducted with physicians affiliated to the French National Society for Internal Medicine, and were classified into typical or atypical Cogan's syndrome according to the Haynes criteria. Clinical data were collected in a standardized manner. A comprehensive literature review using the Medline database and the reference lists of identified articles was performed. RESULTS: Seventeen patients had typical Cogan's syndrome and 15 had atypical Cogan's syndrome. Apart from non-syphilitic interstitial keratitis, the ocular manifestations of patients with atypical Cogan's syndrome were mainly uveitis and episcleritis. All but one patient presented with Ménière-like syndrome, and at the end of follow-up 11 were deaf and 19 additional patients had developed a significant decrease in auditory acuity. Twenty-five patients (78%) developed systemic manifestations, including aortitis in four. Comparison of typical and atypical Cogan's syndrome showed that some systemic manifestations were more common in atypical Cogan's syndrome, but these differences may be explained by reporting bias in the literature. CONCLUSION: Differences regarding the associated systemic manifestations of typical and atypical Cogan's syndrome may reflect reporting bias in the literature. However, the diversity of the ocular and audiovestibular manifestations and the acceptable lengthy delay between the two types of involvement in atypical Cogan's syndrome should make one cautious before accepting this diagnosis as the diagnosis may mimic various other systemic diseases.

ABSTRACT

PURPOSE: This descriptive and epidemiological study was conducted in Mars 2002 in Internal Medicine in order to (1) participate in elaborating a White Book about the speciality, (2) analyse the post-university formation needs of the specialists in Internal Medicine. METHODS: A questionnaire was sent to all specialists in Internal Medicine listed on the ADELI file (n = 2155). For the first three patients seen in consultation and during hospital stay, questioned specialists had to mention the age, sex, origin, motive of the visit, nature of symptoms, complexity of the problem and the nature of the required abilities. They also had to precise the main diagnosis of all patients seen in the same day. RESULTS: Three hundred and sixty answers have been received. Three hundred and thirty two were exploitable. Five thousand six hundred and eleven main diagnosis were listed. Fifteen percent of the questioned specialists did practise in other specialities than Internal Medicine. Orphaned diseases were the most common pathologies carried out in consultation (17%). Patients seen during their hospital stay suffered more frequently from infectious, haematological and malignant diseases. In 55% of the cases, patients were seen in second or third line after a visit to a general practitioner or another specialist. The abilities of the Internal Medicine specialist alone were sufficient in 70% of the cases to solve the problem. Complexity of the problem was evaluated by the specialists themselves at about 45/100 on an analogical scale. CONCLUSIONS: This study inform the medical community about the type of patients treated by the specialists in Internal Medicine, precise the exact nature of their professional exercise and their real need in medical post-university formation.

ABSTRACT

This review focuses on auto-immune diseases which frequently affect women and can have interactions with pregnancy: lupus erythematosus (LES), antiphospholipide syndrome (SAPL), Sjögren's syndrome (GS), rheumatoid arthritis (PR) and auto-immune thyroiditis. LES may flare at the end of a pregnancy and during post-partum. Its biological monitoring during pregnancy is well established. SAPL is at risk of sterility, prematurity, Hellp syndrome, eclampsia and retroplacental hematoma. The main risk, actually risk is foetal loss by placental ischemia, which has to be well known as 2 randomised studies have proven the efficacy of treatments with aspirin +/- subcutaneous heparin. LES, GS and PR can both be associated with anti SS-A +/- anti SS-B antibodies linked to a risk of congenital auriculo-ventricular block, which is fortunately low (less than 5% of the cases). Auto-immune thyroiditis are often revealed during pregnancy and may be enhanced during the six first months of post-partum.

ABSTRACT

INTRODUCTION: Crowned dens syndrome is due to a microcrystalline infringement (hydroxyapatite or calcium pyrophosphate) of the retro-odontoidal ligament of atlas, often leading to the erroneous diagnosis of meningitis or spondylitis. We report on three new cases diagnosed from 1996 to 1999. EXEGESIS: The patients complained of cervicalgies, headaches or fever. The initially evoked diagnoses were meningitis, spondylodiscitis or endocarditis. Clinical exam found meningism and an inflammatory syndrome in all patients. Analysis of the cerebro-spinal fluid realised in two cases was normal. The diagnosis of crowned dens syndrome was assessed in two cases by cervical CT scan of C1/C2. In the third case, chondrocalcinosis of a wrist allowed this diagnosis. We report a probably non fortuitous case of crowned dens syndrome associated with genetic hemochromatosis. A non steroidal anti-inflammatory treatment allowed a dramatic regression of clinical symptoms. CONCLUSION: This entity should be better known; it can mimick numerous diagnosis and be responsible for fever in the long course.

ABSTRACT

PURPOSE: The antifibrotic action of interferon alpha on the liver is now established in hepatitis C (cf. article by T. Poynard). Numerous in vitro experimental evidences may lead people into believing in the efficacy of interferon gamma in patients with mucous membrane and pulmonary fibrosis. CURRENT KNOWLEDGE AND KEY POINTS: A randomized study has confirmed the efficacy of interferon gamma in the idiopathic pulmonary fibrosis, probably by an anti TGF beta action. Several open studies have shown the efficacy of interferon gamma in patients with post-radiation cutaneous fibrosis (Chernobyl survivors, sequelae of radiotherapy for cancer). In systemic sclerosis, several teams have shown that interferon gamma reduced collagen synthesis by sclerodermic fibroblasts in vitro. Four open studies have also confirmed the efficacy of interferon gamma in systemic sclerosis. In our experience concerning 20 patients with diffuse systemic sclerosis, the five years survival with long term therapy was 85% and we observed an improvement in the cutaneous suppleness in 40% of these cases. There was no serious side effect. FUTURE PROSPECTS AND PROJECTS: These encouraging results need to be confirmed by large randomized studies in pulmonary fibrosis and systemic sclerosis. Other indications should be assessed, particularly extra-cutaneous radiation sequelae and in systemic fibrosis (retroperitoneal, mediastinal and cervical).

ABSTRACT

Reported here is the case of a patient who spontaneously recovered from hemophagocytic syndrome associated with acute B19 infection and concomitant Epstein-Barr virus reactivation. The previously healthy 37-year-old-man was hospitalized after 10 days of high fever, arthralgia and arthritis and was determined to have hemophagocytic syndrome. Immunoglobulin (Ig) M antibodies to Epstein-Barr virus (EBV) capsid antigen, early antigen and parvovirus B19 (B19) were found. B19 DNA and low-level EBV DNA were detected in bone marrow, serum and peripheral blood mononuclear cells. The patient recovered spontaneously without any treatment. Two months later anti-B19 IgG antibodies were detected, while at 9-month follow-up, anti-B19 IgM antibodies were no longer detectable and B19 DNA had disappeared from serum. To the best of our knowledge, this is the first report of spontaneous resolution of hemophagocytic syndrome associated with acute B19 infection and concomitant EBV reactivation in an otherwise healthy adult.
