Three cases of resuscitative endovascular balloon occlusion of the aorta (REBOA) in austere pre-hospital environment-technical and methodological aspects.

Background: The present paper describes three cases where ER-REBOA® was used with partial aorta occlusion (AO), by performing a partial resuscitative endovascular balloon occlusion of the aorta or pREBOA, in an austere pre-hospital military environment.In addition, because no specific REBOA algorithm for pre-hospital environment exists yet, this paper seeks to fill this gap, proposing a new pragmatic REBOA algorithm. Methods: Belgian Special Operations Surgical Team applied REBOA in three patients according to a decisional algorithm, based on the MIST acronym used for trauma patients. Only 3 ml, in the first instance, was inflated in the balloon to get AO. The balloon was then progressively deflated, and reperfusion was tracked through changes of end-tidal carbon dioxide (EtCO2). Results: Systolic blood pressure (SBP) before ER-REBOA® placement was not higher than 60 mmHg. However, within the first 5 min after AO, SBP improved in all three cases. Due to the aortic compliance, a self-made pREBOA was progressively achieved while proximal SBP was raising with intravenous fluid infusion. Afterwards, during deflation, a steep inflection point was observed in SBP and EtCO2. Conclusions: ER-REBOA® is suitable for use in an austere pre-hospital environment. The MIST acronym can be helpful to select the patients for which it could be beneficial. REBOA can also be performed with pREBOA in a dynamic approach, inflating only 3 mL in the balloon and using the aortic compliance. Furthermore, while proximal SBP can be convenient to follow the occlusion, EtCO2 can be seen as an easy and interesting marker to follow the reperfusion.

Advance directives from haematology departments: the patient's freedom of choice and communication with families. A qualitative analysis of 35 written documents.

BACKGROUND: In France, advance directives are favourably perceived by most of the population, although the drafting rate is low. This ambivalence is challenging because advance directives are meant to promote the autonomy and freedom of choice of patients. The purpose of this study was to analyse the content of advance directives written by patients suffering from malignant haemopathies to better understand how patients put them into practice. These could be relevant as early as the initial diagnosis of haematological malignancies because of the uncertain course of the disease. METHODS: This was a multicentre, qualitative, descriptive study. The advance directives written by patients with malignant haemopathies treated in one of the six French hospital departments were included in the study from 01/06/2008 to 15/04/2016. A thematic analysis of the advance directives was performed by two researchers: a senior haematologist and a research assistant. RESULTS: The median age of the patients was 69. Most were women (sex ratio: 0.59), living as a couple (57%), with lymphoid pathologies (66%), who were still alive two years after the instructions were written (63%) and had nominated a health care proxy (88.6%). Free texts (62.9%) were richer in content than pre-defined forms. The advance directives were used in three ways: for a purely legal purpose, to focus on medical treatments or actions, or to communicate a message to the family. Three main themes emerged: (1) refusal of medical treatment (100%), in which patients express refusal of life-sustaining care (97.1%). The actual treatments or the moment when they should be limited or stopped were not always mentioned in detail. (2) A desire for effective pain relief to avoid suffering (57.1%) and (3) messages for their family (34.3%), such as funeral arrangements (17.1%) and messages of love or trust (14.3%). CONCLUSIONS: Patients who write advance directives are not necessarily at the end of their lives. Their content mainly conveys treatment wishes, although patients also use them to pass on personal messages to their close family. This emerging role of advance directives to communicate messages within the family should be valued, even if it is not their original purpose.

[Not-for-profit: A report from the fourth annual symposium of ethics held by the National Institute for Blood Transfusion (France)]. / À propos du non-profit : rapport du quatrième symposium annuel d'éthique transfusionnelle de l'Institut national de la transfusion sanguine.

The not-for-profit issue has been debated in November 2016 in Paris; this issue is one of the four canonical pillars of ethical blood donation. It is intimately bound to benevolence though it is distinct, as not-for-profit calls for institutions while benevolence calls for individuals. It is indeed intended that voluntary blood donors do not benefit from their donation and are thus non-remunerated. Not-for-profit is essential since it refers to the public character of blood as a putative public resource aimed at being shared as a tribute of solidarity. A central question however is linked to the capacity- or not -of public sectors to ensure that blood components are universally available, with special mention to plasma derived drugs, without the contribution of the for profit, private sector.

Predictive factors of depressive symptoms of elderly patients with cancer receiving first-line chemotherapy.

BACKGROUND: Depression is the most common psychiatric disorder in geriatrics and oncology. For elderly cancer patients, it has a significant impact on quality of life, morbidity, and mortality. Nevertheless, depression is under-diagnosed and under-treated. Cancer management is key in improving the quality of care in this population. We aim to identify sociodemographic, clinical, and treatment-related factors of depression in elderly patients during chemotherapy, thus allowing early detection of patients in need of specific treatment. Further, we investigate whether chemotherapy efficacy and safety are associated with depression. PATIENTS AND METHODS: A prospective multicenter cohort composed of incident cases of cancer diagnosed in patients 70 years and older, receiving first-line chemotherapy. Depressive symptoms were measured by the Geriatric Depression Scale at baseline and after four chemotherapy cycles. Associations between depressive symptoms during chemotherapy and patients' clinical and treatment characteristics were identified by logistic regression. RESULTS: Among 344 patients measured for depression before chemotherapy, 260 had a second assessment at the fourth treatment cycle. At baseline, 45.4% were depressed, and 44.6% were depressed after the fourth cycle. Independent factors of depression were depressive symptoms at baseline (odds ratio (OR) = 6.7, p < 0.001), malnutrition (OR = 5.1, p = 0.014), and risk of malnutrition (OR = 1.6, p = 0.014). After controlling for missing data, effective chemotherapy was associated with a lower risk of depression (OR = 0.4, p = 0.018). CONCLUSION: We highlight the role of depressive symptoms and nutritional status at baseline, on the occurrence of depressive symptoms during chemotherapy. These factors should be taken into account in any pre-treatment consultation and appropriate nutritional and psychiatric preventative measures established. Copyright © 2016 John Wiley & Sons, Ltd.

[Surgery guided by customized devices: reconstruction with a free fibula flap]. / Chirurgie assistée par dispositifs sur-mesure: reconstruction par lambeau libre de fibula.

The reconstruction of jaws with a free fibula flap can be anticipated virtually. The simulation can be transferred to the operating theater using customized devices obtained from computer-assisted design and manufacturing in a complete digital workflow. Several alternatives are available, from cutting guides to customized titanium osteosynthesis plates, to obtain the best accuracy and reproducibility of reconstruction. Moreover, these new processes allow integrating prosthetic planning concomitantly with reconstruction. We present the virtual three-dimensional planning method for jaw reconstruction with a free fibula flap and the various alternatives of surgery guided by customized devices provided by this planning.

[Double-barrel fibular free flap for mandibular reconstruction: beneficial alternative for dental implanted rehabilitation (5 cases)]. / Lambeau libre de péroné en double barre: intérêt du montage dans les reconstructions mandibulaires pour une réhabilitation prothétique sur implants (5 cas).

INTRODUCTION: As major loss of mandibular bone stock requires a vascularized transfer, fibula free flap reconstruction is considered to be the best free flap for its length and reliability. Its main advantage is to accept dental implants. Single or double-barrel reconstruction can be performed. Double-barrel reconstruction is generally preferred because the bone superposition offers enough height to allow dental implants. MATERIAL AND METHODS: We reviewed five selected cases of double-barrel fibula free flap adaptive mandibular reconstruction performed among a series of 11 oral rehabilitations with planned dental implants, focusing on the technical aspects. RESULTS: Today, dental rehabilitation has been achieved in three double-barrel fibula flaps. Details are reported concerning the implant step. DISCUSSION: In this perspective, we discuss the choice of the reconstructive technique in order to obtain adequate bone height. Early in our experience and for different reasons discussed in the text, we used a single barrel fibula flap. This technique provided sufficient height in some cases, but had to be completed by bone grafts in few patients. Our experience illustrates the usefulness of the double barrel technique which provide definitive bone height sufficient for dental implants. The double-barreled technique should be considered as the best solution.

Prognostic factors of combined viral load and CD4+ cell count responses under triple antiretroviral therapy, Aquitaine cohort, 1996-1998.

OBJECTIVE: To describe the viroimmunologic response and its prognostic factors 6 months after initiating triple antiretroviral therapy in a cohort of HIV-1-infected patients. METHODS: Positive virologic response during follow-up (VL+) was defined as plasma HIV RNA level <500 copies/ml and positive immunologic response (CD4+) as an increase of CD4+ count of at least 50 cells/mm3. Four categories of response were defined: VL+/CD4+; VL+/CD4-; VL-/CD4+ and VL-/CD4-. Prognostic factors were studied through a polytomous logistic regression (VL-/CD4-, as reference). RESULTS: Baseline characteristics of the 478 studied patients were: 22% at AIDS stage, 77% pretreated, median CD4+ cell count 195/mm3 and HIV RNA level 4.42 log. At 6 months 37.5% were VL+/CD4+; 15.7% VL+/CD4-; 23.8% VL-/CD4+ and 23.0% VL-/CD4-. Baseline HIV RNA level was associated to a higher risk of VL-/CD4+ response. More advanced age was associated with a higher risk of isolated immunologic failure (VL+/CD4-), whereas pretreatment and saquinavir therapy were associated with a lower frequency of positive virologic response independently of immunologic response. CONCLUSION: HIV-RNA level, pretreatment, and saquinavir therapy were already known to be linked to therapeutic response. Based on our results, a high baseline HIV-RNA level is associated with isolated immunologic response; moreover, age should be of importance in treatment decision.

Postoperative maxillary cyst following sinus bone graft: report of a case.

Sinus bone grafting with autogenous bone is routinely performed to allow placement of endosseous dental implants. Although numerous maxillary sinuses have been successfully grafted, some complications of this procedure have been reported. These include maxillary sinusitis, resorption, infection and possible failure of grafts, loss of implants after 1-stage surgery, and oroantral fistulae. Only one case of postoperative maxillary cyst developing in the graft has been reported in the literature. Here, the authors report a similar case that necessitated grafting of the cyst with autologous iliac bone.

Changes in CD4+ cell count and the risk of opportunistic infection or death after highly active antiretroviral treatment. Groupe d'Epidémiologie Clinique du SIDA en Aquitaine.

OBJECTIVE: To study the relationship between the CD4+ cell response after initiation of protease inhibitors and the occurrence of opportunistic infections and survival. DESIGN: Prospective observational cohort study. METHODS: HIV-1-seropositive subjects followed-up in HIV centres of Bordeaux University Hospital, Southwest France who were prescribed at least one available protease inhibitor between January and December 1996 were included in this analysis. A Cox model estimated the independent effect of baseline covariates and CD4+ cell response, considered as a time-dependent covariate, on the occurrence of new AIDS-defining opportunistic infection, new AIDS-defining events, new AIDS-defining opportunistic infection or death. RESULTS: A total of 556 HIV-positive patients were prescribed at least one protease inhibitor: 34% saquinavir, 52% indinavir, and 14% ritonavir. Median CD4+ cell count at baseline was 95 x 10(6)/l and mean plasma HIV RNA was 5.0 log10 copies/ml. After a median follow-up of 230 days, 65 patients experienced a new episode of opportunistic infection, 79 patients experienced at least one AIDS-defining event, and 24 had died. On average, the increase in CD4+ cell count was 42 x 10(6)/l (SD, 74) after a median of 49 days. In the multivariate analysis of opportunistic infection or death, each 50% higher CD4+ cell count at baseline was associated with a 23% reduction [95% confidence interval (CI), 14-30] of risk. Each 50% increase in CD4+ cell count during follow-up was associated with a 9% reduction (95% CI, 2-15) of risk, adjusted for the presence of AIDS prior to protease inhibitor therapy (hazard ratio, 3.76 versus absence of AIDS; P < 0.01) and haemoglobin level (hazard ratio, 0.48 if > 11 g/dl versus <11 g/dl; P < 0.01). CONCLUSION: Our results show, at least indirectly, how protease inhibitors might produce clinical stabilization. This result may be due to improved functionality of CD4+ cells in patients started on protease inhibitors.

Low-dose splenic irradiation in the treatment of immune thrombocytopenia in HIV-infected patients.

PURPOSE: To determine the effect of low-dose splenic irradiation on severe Zidovudine-resistant, HIV-1-associated thrombocytopenia (HAT). METHODS AND MATERIALS: Between September 1994 and October 1996, 17 patients were included in a prospective study. The patients met the following criteria for inclusion: hemorrhagic symptoms or a platelet count below or equal to 50 x 10(9)/l and normal numbers of megakaryocytes on bone aspiration. The mean baseline platelet count was 20.3 (+/- 14.4) x 10(9)/l; four patients had a platelet count inferior to 10 x 10(9)/l. Splenic volume was defined by ultrasonography. A total dose of 9 Gy was given using an isocentric parallel pair field technique. RESULTS: One month after the end of treatment six patients had a significant rise in their platelet count. Clinically, hemorrhagic symptoms stopped for all patients that were symptomatic. Unfortunately, duration of response was short because for one patient only the platelet count remains stable with a follow-up of 6 months. All patients are alive and in recent evaluation, with four out of eight patients receiving a combination of antiretroviral therapy had a platelet count above 50 x 10(9)/l. CONCLUSION: Our results are disappointing concerning the duration of response, especially comparatively to those reported in autoimmune thrombocytopenia. Mechanisms of HAT are more complex, and megakaryocytes' infection may play an important role. Splenic irradiation should be considered as palliative treatment for the minority of patients with severe bleeding that does not respond to standard medical treatment.

[Splenic lymphoma with villous lymphocytes: morphologic, immunologic and molecular study. Report of three cases]. / Lymphome splénique à lymphocytes villeux: étude morphologique immunologique et moléculaire. A propos de trois cas.

Splenic lymphoma with villous lymphocytes (SLVL) is a low grade lymphoproliferation characterized by a massive splenomegaly, an absence of lymphadenopathy and the presence in the peripheral blood of atypical B-lymphocytes with hairy-cell appearance. We have studied the morphological, immunological and molecular characteristics of 3 cases of SLVL. SLVL presented on blood smears characteristic irregularities of the plasma membrane consisting in thin and short villi unevenly distributed. The main phenotype was CD5-, CD11c+, and CD25-, but individual SLVL cases can not be identified by using immunohistochemical criteria alone. Clonal rearrangements of the immunoglobulin heavy chain gene were found in all 3 cases and in one case presented a bcl2-JH rearrangement. SLVL are clonal B-cell lymphoproliferations and can be associated with t(14; 18) translocation.

Treatment of mixed cryoglobulinemia with recombinant interferon alpha and adjuvant therapies. A prospective study on 20 patients.

In order to evaluate the efficacy of interferon alpha (IFNa) in mixed cryoglobulinemia (MC), a prospective multicenter clinical trial was conduced in April 1992. It consisted of treating 20 clinically symptomatic MC patients with IFNa for 26 weeks. Hepatitis C virus (HCV) infection was detected in 16 patients. A complete or partial clinical remission was obtained in 12 patients (60%). Eleven of these 12 responders (91.6%) experienced a clinical relapse less than 12 months after the end of therapy. Side effects were noted in 10 patients (50%). It was concluded that subcutaneously administered IFNa does not provide long-term remission.

Autologous blood progenitor cell transplantation in high-risk multiple myeloma.

The aim of the study was to evaluate the feasibility and the efficacy of high-dose chemoradiotherapy followed by autologous hematopoietic stem cell support with peripheral blood progenitor cells (PBPC) harvested after high-dose cyclophosphamide (HDCYC) treatment in patients with high-risk multiple myeloma (MM). Inclusion criteria were: age less than 65 years and high-risk MM defined as stage II MM, stage III MM, refractory or relapsed MM. The design of the study was: 1) HDCYC +/- hematopoietic growth factors followed by PBPC collection, and 2) high-dose melphalan combined with total body irradiation (or busulfan for previously irradiated patients) followed by PBPC reinfusion (ABPCT). All 60 patients completed the procedure except two who died from infection after HDCYC and another of acute cardiac failure after reinfusion of PBPC. Out of the 60 evaluable patients, three failed to respond while the other 57 achieved either a partial (n = 33) or complete (n = 24) response. Thirty-one patients progressed or relapsed after a median duration of response of 15 months (range: 3-43). The median follow-up for the other 26 responder patients was 24 months (range: 2-66). Twenty-one patients died, 18 of MM (2 after failure, 16 after relapse) and three responders of lung cancer (n = 1) and infection (n = 2). In conclusion, this study shows that this therapeutic approach is feasible and efficient.

[Comparative efficacy of sustained release verapamil and captopril in mild to moderate arterial hypertension by ambulatory measurement and occasional measurement]. / Efficacité comparée du vérapamil à libération prolongée et du captopril dans l'hypertension artérielle légére à modérée par la mesure ambulatoire et mesure "occasionnelle".

The evaluation of mild to moderate hypertension must be carried out under the conditions in which treatments are usually prescribed, i.e., in general practice. After specific training of the physicians in the methods used, we evaluated the efficacy and safety of a new formulation of verapamil by comparing it with a reference drug: captopril. The main assessment criterion was the restoration of normal blood pressure in mildly to moderately hypertensive patients (blood pressure in excess of 160/95 mmHg). Blood pressure was evaluated by two methods: a mercury column sphygmomanometer, after the patient had rested in a half-sitting position for 10 minutes, and the ambulatory measurement of blood pressure (AMBP) using the SpaceLabs system. The results of this study involving 40 patients followed up for 3 months by 8 GPs in collaboration with our blood pressure unit were as follows: on verapamil, 47% of patients recovered normal values after 30 days of treatment and 71% after 60 days (with no change in dosage). On captopril, the normalization rates were 22 and 27% respectively. The highly significant reduction of blood pressure found by the "occasional" measurement for both treatments (p less than 0.001) was only faintly reflected by AMBP. Verapamil induced a reduction of nighttime blood pressure with no significant impact on heart rate. The clinical, paraclinical and electrocardiographic safety of both treatments was good.
