Goal. – This study had for aim to analyze the epidemiology of strains identified in blood cultures (hoˆpital d’instruction des arme´es Percy, Clamart, France, hematology unit) to compare the rate of identified micro-organisms with literature data, and to search for a possible correlation between antibiotherapy management and evolution of resistance profiles.Material and methods. – All the micro-organisms (N =690) collected over seven years (January 1996 to December 2002), from blood cultures of hospitalized patients in conventional and sterile sector were studied.Results. – Gram positive cocci rate (GPC) was 62.6% and Gram negative bacilli (GNB) 31.3%. Evolution in time showed a decrease of GPC and an increase of GNB, notably the non fermenting Gram negative bacilli, leading to an equal rate by 2001–2002. The most frequently identified species were Staphylococcus epidermidis (36.4%), Escherichia coli (8.7%), Pseudomonas aeruginosa (6.8%), and Staphylococcus aureus (4.9%). The rate of methicillin-resistant staphylococci was 63.6%. Fifty-five percent of E. coli strains had a penicillinase phenotype. Pseudomonas aeruginosa resistance was 8.5, 8.5, 6.4 and 8.5%, respectively for ceftazidime, piperacillin–tazobactam, imipenem, and amikacin.Conclusion. – This study showed a tendency to inversion of former bacteremia epidemiology with increasing negative Gram bacilli. It justifies the antibiotherapy protocols adopted in the hematology unit. [Copyright &y& Elsevier]

Introduction: The synovial wrist ganglion is a particularly common pathology of which the first "complication" is recidivism. The main objective of our study was to determine the rate of recurrence of this pathology in a series of arthroscopic patients. The secondary objective was to assess patient satisfaction well after the operation., Material and Methods: Our study was observational and retrospective and involved 30 patients (17 dorsal and 13 palmar cases) aged 41 years on average. The patients underwent an arthroscopic procedure for a palmar or dorsal ganglion of the wrist between March 2007 and April 2013. The data were collected by re-reading the files and conducting telephone interviews. Each patient answered a questionnaire about the operation, after-treatment, and their satisfaction well after the surgery. At the end of the interview, we calculated the Patient Rated Wrist Evaluation (PRWE) score., Results: The mean follow-up was 4.6 years. A recurrence was noted in 4 (13%) cases, at an average delay of 9 months (6 months-1 year). There were only 2 patients (6.7%) that experienced the complication of complex regional pain syndrome type 1. Twenty-eight (93%) patients experienced improvement in postoperative pain. For 27 (90%) patients, firm-handed activities could be practised without limitation. The average time to resumption of activities of daily living was 27.1 days (1-240 days), resumption of firm-handed activities was 56 days (15-360 days), and return to work was 47.5 days (1-360 days). The mean PRWE score was 6.9/50 (0-34) for pain and 1.38/50 (0-8) for function., Conclusion: The 13% recurrence rate is on the average of what is observed in the literature. Later satisfaction with the intervention is very good, and complications remain rare.Studies tend to show a lower rate of complications and recurrence following arthroscopic treatment, but to date, no randomized comparative series between the two methods has yet revealed any significant difference in these two points. A study of this type on a large scale could make it possible to highlight one of these treatment approaches.

Lateral epicondylitis of the elbow is a relatively common pathology and would involve 1-3% of the overall population. Lack of consensus on surgical techniques reflects the difficulty of understanding and treating this disease. Our prospective study reports the results of its arthroscopic treatment on 14 patients operated on between 2009 and 2012. The mean follow-up was 7.15 months. All patients underwent a well conducted medical treatment for an average of 32.5 months. The operation was carried out under regional anesthesia in an outpatient. The technique included a time of joint exploration, joint capsulotomy and a transverse division of the pathological tendon of extensor carpi radialis brevis (ECRB) and extensor digitorum communis (EDC). The value on the visual analogic scale (VAS) at rest and during exercise increased from 2.85 to 0.43 and from 7.71 to 2.43, respectively, then remained stable over time. Professional activity was resumed on average at 9.1 weeks. Neither intraoperative nor postoperative complications were found. No laxity was observed. The Mayo Clinic and DASH scores were significantly improved from 52.14 to 92.5 and from 54.11 to 9.7, respectively. Overall, we observed 11 very good and three good results. Although our prospective series has a few patients and limited follow-up, our results are better or similar than those reported in the literature on pain relief and functional recovery. In contrast, the average recovery of professional activity was longer. Elbow arthroscopy, less invasive than open procedures, and allowing further joint exploration, seems an excellent alternative technique in this indication., (Copyright © 2013.

We report the case of a 36-year-old women with Hodgkin's disease treated with polychemotherapy and bone marrow autograft. Progressive growth of a thymic mass suggested possible relapse four months after treatment withdrawal. This mass did not exhibit gallium-67 uptake but showed strong affinity for 18-FDG (SUV=6.8). Surgical biopsy ruled out recurrence of Hodgkin's disease of the thymus and led to the diagnosis of thymic rebound. The aspect of the thymic compartment returned to normal spontaneously at one year.

Purpose: The purpose of this study was to evaluate the arthroscopically assisted Bristow-Latarjet procedure. The aim was to use arthroscopic guidance to assist in positioning of the coracoid bone block onto the anterolateral aspect of the glenoid. The feasibility of this technique and its efficacy, reproducibility, and potential neurovascular complications were evaluated., Methods: A minimally invasive technique was used to harvest the coracoid bone block and the attached coracobiceps tendon. A portal was created through the subscapularis muscle and, under arthroscopic guidance, the anterior aspect of the glenoid was cleaned and reamed before the bone block was placed. Cannulated screws (3.5 mm) were used to fix the vertically oriented bone block to the glenoid. The size of the bone block, its position on the glenoid, and its relation to the subscapularis tendon and the musculocutaneous and axillary nerves were recorded., Results: In all 5 cadavers, the bone block was well positioned and was fixed to the anteroinferior part of the glenoid. No lesions of the cephalic vein or of the surrounding neurovasculature were observed., Conclusions: This study demonstrated the safe and effective use of this arthroscopically assisted technique for correct positioning of the coracoid bone block at the anterolateral aspect of the glenoid in the cadaveric shoulder. Arthroscopy facilitated adequate reaming of the anterior glenoid and aided in optimal positioning of the bone block., Clinical Relevance: This cadaveric study highlights the advantages offered by an arthroscopically assisted Bristow-Latarjet procedure, which optimizes positioning of the block and ensures adequate reaming of the anterior glenoid, thereby potentially reducing the risks of early nonunion and late arthritis--complications commonly associated with the classical Bristow-Latarjet technique.

Introduction: Rituximab is an alternative treatment for hairy cell leukemia, when the standard treatments are unavailable., Case: An 82-year-old woman was diagnosed with hairy cell leukemia. The severity of her neutropenia ruled out purine analogs, while heart disease and age both contraindicated use of interferon. Rituximab, in four weekly treatments, was effective from the first treatment and the positive response was sustained thereafter., Discussion: Rituximab may be used to treat hairy cell leukemia, especially for patients refractory to purine analogs or after relapse or in the case of severe neutropenia, when interferon is contraindicated.

Introduction: Hodgkin's disease with initially predominant bone marrow involvement is observed in 1% of cases., Observation: A case of Hodgkin's disease with massive bone marrow invasion, manifested by pancytopenia in the context of fever and alteration in general status of health, with little or non superficial peripheral lymph nodes. The bone marrow biopsy revealed extensive myelofibrosis with rare Reed-Sternberg cells., Discussion: This case report is inscribed within the framework of the exceptional massive bone marrow forms of Hodgkin's disease, described by Duhamel et al. in 1979. We believe that metabolic imaging with 18F-FDG positron emission tomography (PET) is a valid examination in orienting diagnosis and post-therapy assessment.

From 1978 to 2002, 30 patients presenting hairy-cell leukemia were seen in two different hospitals. We reviewed clinical, biological and therapeutic data. At diagnosis, the median age was 67.8 years; 47% were clinically asymptomatic, 12 patients had anaemia, 15 thrombocytopenia (platelets<100,000/mm3). A treatment was required for 29 patients. At the end of the study, 27 patients are alive and none died because of the disease. This study confirms the good prognosis of hairy-cell leukemia, especially since the advent of new therapeutics such as purine analogs. Based on the results in this series, we examined the different aspects of the disease referring to diagnosis, treatment and prognosis.

Spontaneous hematoma in the ilio-psoas muscle is an uncommon condition, usually observed as a complication of anticoagulation or hemophilia. Clinically, the onset is marked by violent pain in the territory of femoral nerve and/or psoitis. The diagnosis is confirmed by echography or CT-scan. The most serious complications are loss of self-sufficiency and neuro-muscular after-effect. Surgery is recommended in patients with neurological suffering, followed by early physiotherapy. We report the case of a 42-year-old man, with an ilio-psoas muscle hematoma, revealing chronic myeloid leukemia, without any hemostasis disorder.

Introduction: Lymphoproliferative syndromes are rarely complicated by medullar fibrosis simulating myeloid splenomegaly., Observation: We report an unusual case of an IgD myeloma revealed in a context of myeloid splenomegaly in a 37 year-old man, initially admitted for severe anaemia associated with a voluminous splenomegaly., Commentaries: The occurrence of myeloid splenomegaly during myeloma is extremely rare and only 14 cases have been reported. In this context, myelofibrosis is secondary to plasmocyte invasion of the bone marrow and regresses, or disappears, following specific treatment of the myeloma. The hypothesis evoked to explain the appearance of a secondary myelofibrosis is the "inappropriate" secretion, by the malignant plasmocyte clone, of functional analogs of pro-fibrosis cytokines, usually secreted by the mega-caryocyte precursors implied in myeloid splenomegaly.

Bone marrow grafting following accidental irradiation exposure should be viewed in the perspective of a severe myeloablative syndrome linked to high medullary damage for a dose range higher than 6-8 Gy, resulting in very late or no recovery. Prognosis will depend on the presence or absence of radio-combined injuries, the toxicity of the transplant procedure, and the risk of rejection induced by insufficient percritical immunosuppression. It is in this context that new cell therapy modalities, which combine enhanced peripheral hematopoietic cell engraftment and high immunosuppressive conditioning regimen with low extrahematological toxicity, inducing early and stable mixed lymphomyeloid chimerism with minimal morbidity, can be considered. Such an approach is being evaluated in the treatment of patients with hematological malignancies at high risk of transplant-related mortality using conventional bone marrow methods.

Purpose: To determine the prognostic factors and outcome of first-line induction failure Hodgkin's disease patients who were treated with a salvage regimen of high-dose chemotherapy and autologous stem-cell transplantation, and to compare them with matched, conventionally treated patients., Patients and Methods: We retrospectively analyzed data relating to 86 Hodgkin's disease patients who underwent autologous stem-cell transplantation after failure of the first chemotherapy regimen, either because they did not enter a complete remission and experienced progression of disease less than 3 months after the end of their first-line treatment or because they showed evidence of disease progression during first-line therapy. Graft patients were matched with 258 conventionally treated patients (three controls per case) for age, sex, clinical stage, B symptoms, and time at risk; patient data were obtained from international databases., Results: Among the 86 graft patients, the median age at diagnosis was 29 years (range, 14 to 57 years). Thirty-nine percent of patients had stage II disease, 23% had stage III disease, and 38% had stage IV disease. Seventy percent of the patients received chemotherapy and 30% received combined modality therapy; 60% of the patients received a seven- or eight-drug regimen. After this first-line treatment, 91% had disease progression and 9% had a brief partial response. Eighty patients received a second-line treatment; pretransplantation status was as follows: 24% of patients had a complete remission, 38% had a partial remission (PR), 14% had stable disease, and disease progression occurred in 24%. With a median follow-up of 22 months (range, 4 to 105 months) from diagnosis, the 5-year event-free survival and overall survival rates from transplantation were 25% and 35% (95% confidence intervals, 15 to 36 and 23 to 49), respectively. In multivariate analysis, the pretransplantation disease status after salvage therapy was the only significant prognostic factor for survival (PR: relative risk = 2.8, P = .017; progressive disease: relative risk (RR) = 5.26, P < .001). From diagnosis, the 6-year overall survival rates of the graft patients and 258 matched conventionally treated patients were 38% and 29%, respectively (P = .058)., Conclusion: Autologous stem-cell transplantation represents the best therapeutic option currently available for patients with primary induction failure and is associated with acceptable toxicity. Response to second-line treatment before high-dose chemotherapy is the only prognostic factor that can be correlated with survival.

We retrospectively investigated the feasibility and the toxicity of autologous stem cell transplantation (ASCT) in 21 cases of systemic amyloidosis (AL). The conditioning regimens consisted of high-dose melphalan (HDM) alone (n = 18) or in combination with 12 Gy total body irradiation (n = 3). Toxic death rate was high: 9/21 patients (43%) died within the first month following ASCT, and 10/12 surviving patients achieved a response. With a median follow-up of 14 months, the OS and the EFS rates at 4 years were 57.1% (+/-10.8) and 29.9% (+/-14.5) respectively for the whole group. The major prognostic factor for both response and survival was the number of clinical manifestations at the time of ASCT, of the following five criteria, i.e. creatinine clearance < 30 ml/min, nephrotic syndrome with urinary protein excretion > 3000 mg/24 h, congestive heart failure, neuropathy, or hepatomegaly associated with alkaline phosphatase level > 200 IU/l. For patients presenting with two or more clinical manifestations the 4-year OS and EFS were both 11.1% compared with 91.7% and 46.3% respectively in patients with fewer than two clinical manifestations at the time of ACST. We conclude that ASCT is feasible in AL in a subset of patients with fewer than two clinical manifestations at the time of ASCT. Given the severe extra-haematological toxicity, ASCT should not be considered in other cases.
