Abstract
OBJECTIVES Graves' disease (GD) is a rare auto-immune disorder in pediatric population. The association between GD and thymic hyperplasia was rarely reported in children. Diagnosis and management of GD are challenging in children. CASE PRESENTATION This report presents the case of a 5-year-old girl with a personal history of asthma and congenital bilateral isolated clinical anophthalmia who presented with acute congestive heart failure, sinus tachycardia and atypical signs of orbitopathy with edema and erythema of the lower right eyelid and excessive tearing. The diagnosis of GD was based on detecting a suppression of serum TSH level and the presence of high titers of TRAbs. Relapse occurred after 10 months of antithyroid drugs with chief complaints of palpitations, dyspnea and dysphagia. Computed tomography showed heterogeneous anterior mediastinal mass with no invasion into the surrounding tissue. The marked shrinkage of the mass after radioiodine therapy supported the diagnosis of thymic hyperplasia associated with GD. CONCLUSIONS The presence of clinical anophthalmia may be a confusing factor for the diagnosis of Graves' ophthalmopathy. Recognition of the association between GD and thymic hyperplasia would avoid invasive diagnostic procedures and unnecessary surgical resection. Radioiodine therapy may be used in young children with repeated relapses of GD.

Abstract
The efficacy of an antitumoral vaccine relies both on the choice of the antigen targeted and on its design. The tumor antigen survivin is an attractive target to develop therapeutic cancer vaccines because of its restricted over-expression and vital functions in most human tumors. Accordingly, several clinical trials targeting survivin in various cancer indications have been conducted. Most of them relied on short peptide-based vaccines and showed promising, but limited clinical results. In this study, we investigated the immunogenicity and therapeutic efficacy of a new long synthetic peptide (LSP)-based cancer vaccine targeting the tumor antigen survivin (SVX). This SVX vaccine is composed of three long synthetic peptides containing several CD4+ and CD8+ T-cell epitopes, which bind to various HLA class II and class I molecules. Studies in healthy individuals showed CD4+ and CD8+ T-cell immunogenicity of SVX peptides in human, irrespective of the individual's HLA types. Importantly, high frequencies of spontaneous T-cell precursors specific to SVX peptides were also detected in the blood of various cancer patients, demonstrating the absence of tolerance against these peptides. We then demonstrated SVX vaccine's high therapeutic efficacy against four different established murine tumor models, associated with its capacity to generate both specific cytotoxic CD8+ and multifunctional Th1 CD4+ T-cell responses. When tumors were eradicated, generated memory T-cell responses protected against rechallenge allowing long-term protection against relapses. Treatment with SVX vaccine was also found to reshape the tumor microenvironment by increasing the tumor infiltration of both CD4+ and CD8+ T cells but not Treg cells therefore tipping the balance toward a highly efficient immune response. These results highlight that this LSP-based SVX vaccine appears as a promising cancer vaccine and warrants its further clinical development.

Abstract
The observation in a certain number of subjects of an atypical iris depigmentation led us to study this phenomenon. Therefore, the authors engaged in a prospective study of 398 subjects (100 cases in the city of Marrakesh, and 298 in the city of Dakhla). The geography, clinical signs and environmental factors were studied. Depigmentation was observed in 55% of the population of Marrakesh and 77% of the population of Dakhla. It is bilateral, symmetric, very progressive, always begins in the inferior one-third of the iris, and always spares the superior iris covered by the eyelid. By the time the depigmentation reaches the middle one-third, the inferior one-third also begins to demonstrate stromal atrophy: (26 cases). Of the 45 subjects with normal iris pigmentation, 31 cases spend more than 8 hours per day in the shade, and 26 cases constantly use some means of solar protection (sunglasses, caps, "Taraza", "Feroual"). Thus, this acquired iris depigmentation of an ascending nature, accompanied by an advanced stage involving primarily inferior iris atrophy, appears to be closely associated with exposure to the sun. Ascending solar iris degeneration, if we may refer to it as such, is a clinical entity never before reported in the literature. Now that we are faced with this new condition, numerous questions arise, to which future research must respond. Are there other factors in addition to sun exposure, which may lead to the depigmentation? Does this condition lead to further ocular pathology (due to the depigmentation and stromal atrophy)? Must solar protection be prescribed systematically for anyone at risk?

Abstract
OBJECTIVE To evaluate the prognostic value of HER2 expression in non-muscle invasive bladder transitional cell carcinoma (TCC) with special emphasis in the high grade population. MATERIALS AND METHODS (PATIENTS): Tissue microarrays (TMA) were performed with representative TUR-B specimens from 84 patients with non-muscle invasive bladder TCC (40 pT1GII and 44 pT1GIII) treated in our institution. Depth of invasion and grade were uniformly assigned by the same pathologist who performed blind immunohistochemical analysis with Hercep test: 3+ was considered strong positive HER2 overexpression. Other clinico-pathological variables were also assessed. RESULTS HER2 protein overexpression was detected in 30/44 (68.2%) pT1GIII lesions and predicted recurrence in this subgroup of bladder TCC (p<0.01). Negative HER2 expression was detected in 26/40 (65%) cases with pT1GII TCC, and this condition was more frequent in unifocal tumours, without angiogenesis, with low recurrence rate and without progression. Recurrence-free survival can also be anticipated by HER 2 expression within pT1GII tumours (p<0.01). CONCLUSION HER2 expression using Hercep test may be useful to predict recurrence in non-muscle invasive bladder TCC. The potential application of this study, especially regarding prediction of response to BCG, should be prospectively confirmed in multi-institutional trials.

Abstract
In the present study, the sorption behavior of cesium was investigated in Ain Oussera soil around the Es-Salam reactor facility. This study was conducted using batch method under different physicochemical conditions including contact time, ionic strength, pH, solid/liquid ratio and temperature. The results showed that sorption followed pseudo-second-order kinetics with a good regression coefficients (R(2)=0.999). The activation energies were 11.26 and 15.21 kJ mol(-1) which correspond to ion-exchange-type sorption mechanism. The adsorption was favored at low temperature and it was exothermic (ΔH(0)<0, with average value of -1.97 kJ mol(-1)) and spontaneous (ΔG(0)<0, with average value of -11.97 kJ mol(-1) at 23°C and -13.2 kJ mol(-1) at 60°C). The presence of competing cations such as K(+) and Ca(2+) ions in groundwater can significantly reduce the Cs adsorption onto soil. Desorption reaction was also investigated using three reagents with different ionic strengths (deionized water, groundwater and 0.1M KCl solution). The results showed that Cs ions were preferentially distributed onto high affinity sorption sites.

Abstract
Primary leiomyosarcoma (LMS) of the pancreas is a rare mesenchymal neoplasm (0.1% of pancreatic tumors) with only 35 cases reported in the world literature. We describe a 36th case. This tumor affects adults in the fifth decade of life, especially men. Its diagnosis is difficult and is based on immunohistochemical analyses that reveal smooth muscle cell markers. We report the case of a patient with primary LMS in the head of the pancreas. He underwent a pancreaticoduodenectomy for both diagnosis and treatment after imaging was unable to provide a precise diagnosis. The discussion covers the clinical, diagnostic, immunohistochemical, and therapeutic characteristics of this neoplasm.

Abstract
AIM The aim of this study was to report the experience of the department of general surgery (Aile III) Ibn Rochd Hospital in surgical management of hyperparathyroidism in patients with end-stage renal disease (ESRD). METHODS Fifty seven patients (24 M, 33F) with hyperparathyroidism underwent surgical parathyroidectomy from 1998 to 2004. Surgical indication was established according to clinical or biological assessment. Fifty nine operations were performed (57 first-hand cervicotomies and resumptions in too cases). RESULTS Histological examination of parathyroid gland specimens disclosed adenoma in 33 patients and hyperplasia in 14 patients. The follow-up was normal in 52 patients, marqued by cervical hematoma in 2 cases and death was deplored in 4 patients. The post-operative calcium level was in the normal range in 43 cases, low comparatively to the baseline in 12 cases and high in 2 cases. The PTH levelwas normal in 55 patients and high in two patients. Long-term outcome was evaluated in 36 patients mean follow-up (18 months). A good evolution was noted in all patient referring to clinical, biological and radiological investigations. CONCLUSION That, in our context, surgical parathyroidectomy still an appropriate approach for the treatment of hyperparathyroidism in patients with end-stage renal disease.

Abstract
BACKGROUND Plasmodium falciparum merozoite surface protein 3 is a malaria vaccine candidate that was identified, characterised, and developed based on a unique immuno-clinical approach. The vaccine construct was derived from regions fully conserved among various strains and containing B cell epitopes targeted by human antibodies (from malaria-immune adults) that are able to mediate a monocyte-dependent parasite killing effect. The corresponding long synthetic peptide was administered to 36 volunteers, with either alum or Montanide ISA720 as adjuvant. METHODS AND FINDINGS Both formulations induced cellular and humoral immune responses. With alum, the responses lasted up to 12 mo. The vaccine-induced antibodies were predominantly of cytophilic classes, i.e., able to cooperate with effector cells. In vitro, the antibodies induced an inhibition of the P. falciparum erythrocytic growth in a monocyte-dependent manner, which was in most instances as high as or greater than that induced by natural antibodies from immune African adults. In vivo transfer of the volunteers' sera into P. falciparum-infected humanized SCID mice profoundly reduced or abrogated parasitaemia. These inhibitory effects were related to the antibody reactivity with the parasite native protein, which was seen in 60% of the volunteers, and remained in samples taken 12 mo postimmunisation. CONCLUSION This is the first malaria vaccine clinical trial to clearly demonstrate antiparasitic activity by vaccine-induced antibodies by both in vitro and in vivo methods. The results, showing the induction of long-lasting antibodies directed to a fully conserved polypeptide, also challenge current concepts about malaria vaccines, such as unavoidable polymorphism, low antigenicity, and poor induction of immune memory.

Abstract
INTRODUCTION The tuberculosis isolated tumoral spleen is rare, even in the countries to strong tubercular endemic. EXEGESIS From an observation, concerning an important, tumoral and isolated splenomegaly in 48-year-old-man. The authors put the accent on his tumorous variety by the clinic, the imagery and on macroscopic appearance of the operative piece. Are discussed the isolated character, the way of dissemination, the site of initial infestation and the deceitful character of haematological manifestations. A splenectomy to diagnostic and therapeutic goal have been realised, associated to the chemotherapy. CONCLUSION This is an expression of the profound organ's tuberculosis rich on endothelial reticular system.

Abstract
We describe novel peptide-protein microarrays, which were fabricated using semicarbazide glass slides that permitted the immobilization of glyoxylyl peptides by site-specific ligation and the immobilization of proteins by physisorption. The arrays permitted the simultaneous serodetection of antibodies directed against hepatitis C virus (HCV core p21 15-45 peptide, NS4 1925-1947 peptide, core, NS3, NS4, and mixture of core, NS3, NS4, and NS5 antigens), hepatitis B virus (HBc, HBe, and HBs), human immunodeficiency virus (Gp41 and Gp120 for HIV-I and Gp36 for HIV-II), Epstein-Barr virus (VCAp18 153-176 peptide), and syphilis (rTpN47 and rTpN17) antigens using an immunofluorescence assay. Peptide-protein microarrays displayed high signal-to-noise ratios, sensitivities, and specificities for the detection of antibodies as revealed by the analysis of a collection of human sera referenced against these five pathogens.

Abstract
Histoid leprosy is a particular variant of lepromatous leprosy presenting as cutaneous or subcutaneous nodular and/or plaque-like lesions arising form apparently normal skin. It is characterized histologically by spindle-shaped histiocytes in interlacing bundles and whorls, containing numerous intact and rod-shaped Mycobacterium leprae. It can occur de novo or secondary in patients treated for a long course by dapsone alone. We describe a case of lepromatous leprosy treated according to the national Moroccan protocol who developed histoid lesions during his treatment by dapsone. The patient responded well to fluoroquinolone, rifampicin and clofazimine, with however, the occurrence of erythema nodosum leprosum.

Abstract
We describe the highly conserved sequence 56-68 of the HIV Nef protein as the first promiscuous HLA-DQ HIV-derived peptide. The Nef peptide exhibits an albeit rare capacity to bind 6 different HLA-DQ molecules whereas no binding is observed with the 10 HLA-DR molecules tested. In agreement with these data, after immunization with the Nef peptide, HLA-DQ transgenic Abeta degrees mice display a vigorous cellular and humoral response while the specific immune response of HLA-DR expressing mice is minimal. The promiscuous potentiality of the Nef 56-68 peptide in humans has been confirmed by ex vivo immunization experiments with CD4+ T cells from 14 healthy donors expressing different HLA genotypes. Nef 56-68 specific CD4+ T cells rapidly acquire a memory cell phenotype and are characterized by the preferential usage of the TCR Vbeta 6.1 gene segment and predominant production of IFN-gamma. Taken together, these data indicate that the Nef 56-68 peptide constitutes an attractive component of vaccines aiming at inducing or enhancing HIV-specific T cell immunity.

Abstract
IgG devoid of neutralizing activity and isolated from donor plasma by chromatography formed immune complexes with coxsackievirus B4 (CVB4) and significantly increased the infection of peripheral blood mononuclear cells with CVB4. The major host cells for CVB4 infection enhanced with IgG are monocytic CD14+ cells. The roles of CVB and adenovirus receptor and Fcgamma receptor II and III have been shown. Increased viral replication and the release of infectious particles were demonstrated when interferon (IFN)-alpha produced by infected cells was first neutralized by use of antibodies. The CVB4 IgG-induced synthesis of IFN-alpha by monocytes reflected entry and uncoating of CVB4 but not of viral replication and required the presence of CVB4 RNA inside the cells. Thus, CVB4 can infect monocytes by an antibody-dependent mechanism through interactions between the virus, antiviral antibodies, and specific receptors that result in IFN-alpha production.

Abstract
Coxsackievirus B4 (CVB4) can be found in circulating blood of patients; however, the interaction of CVB4 with peripheral blood mononuclear cells (PBMCs) is poorly understood. CVB4 induced low levels of IFN-alpha synthesis in PBMCs from healthy donors. In contrast, preincubation of infectious CVB4 with plasma from these donors containing anti-CVB4 antibodies strongly enhanced the synthesis of IFN-alpha. IgG obtained from plasma by chromatography formed immune complexes with CVB4 and increased significantly the CVB4-induced production of IFN-alpha by PBMCs. These antibodies did not have a neutralizing effect on CVB4 infection of Hep-2 cells. The role of CVB and adenovirus receptor (CAR), FcgammaRII and FcgammaRIII in the increased synthesis of IFN-alpha induced by CVB4 preincubated with IgG was shown by inhibition with specific antibodies. The major interferon-alpha-producing cells in response to CVB4-IgG complexes were CD14(+) cells and monocyte-enriched PBMCs. With the latter, detection of IFN-alpha by immunostaining was positive whereas in monocyte-depleted PBMCs it was not. This study shows that CVB4-induced synthesis of IFN-alpha by PBMCs can be enhanced by an antibody-dependent mechanism through interactions between the virus, non-neutralizing antivirus antibodies, FcgammaRII and III and CAR.

Abstract
Non functional retroperitoneal paragangliomas are rare tumors: less than 50 cases are reported in the literature. They are usually asymptomatic and can attain big dimensions. The authors report a case diagnosed by histological examination of the operative specimen. Malignant tumors more frequent than the benign tumors present with a regional extension and delayed metastases. The treatment is completed by surgical excision. Radiotherapy and chemotherapy can be used for palliation of symptoms.

Abstract
We have recently described that sustained Plasmodium falciparum growth could be obtained in immunodeficient mice. We now report the potential of this new mouse model by assaying the effect of the passive transfer of antibodies (Abs) which in humans have had a well-established effect.Our results show that the total African adult hyperimmune immunoglobulin Gs (HI-IgGs) strongly reduce P. falciparum parasitemia similarly to that reported in humans, but only when mice are concomitantly reconstituted with human monocytes (HuMNs). In contrast, neither HI-IgGs nor HuMNs alone had any direct effect upon parasitemia. We assessed the in vivo effect of epitope-specific human Abs affinity-purified on peptides derived either from the ring erythrocyte surface antigen (RESA) or the merozoite surface protein 3 (MSP3). The inoculation of low concentrations of anti-synthetic peptide from MSP3, but not of anti-RESA Abs, consistently suppressed P. falciparum in the presence of HuMNs. Parasitemia decrease was stronger and faster than that observed using HI-IgGs and as fast as that induced by chloroquine. Our observations demonstrate that this mouse model is of great value to evaluate the protective effect of different Abs with distinct specificity in the same animal, a step hardly accessible and therefore never performed before in humans.

Abstract
The role of cytokines in the control of HCMV infection has been studied in THP-1 cells, a macrophage-like cell model and in MRC-5 cells. HCMV replication was studied by immune detection of viral immediate-early antigens (IEA) and virus yield was evaluated in MRC-5 cells by immunoperoxidase staining. Pretreatment of MRC-5 and phorbol 12-myristate 13-acetate (PMA)-treated THP-1 cells with IFN-alpha or IFN-gamma for 24 hr prior to the infection reduced the number of infected cells and virus yield. A synergistic anti-CMV activity in synthesis of early proteins was obtained with these cytokines in combination with TNF-alpha in differentiated THP-1 cells only. Treatment of HCMV-infected differentiated THP-1 cells or MRC-5 cells with IFN-alpha or IFN-gamma alone had no inhibitory effect on virus replication, however the virus yield was reduced with ganciclovir. A synergistic anti-CMV activity in virus yield was obtained only when infected differentiated THP-1 cells were treated with ganciclovir in combination with IFN-gamma. The current study shows that IFN-alpha and IFN-gamma can play a role in the reduction of HCMV replication in macrophage-like cells and in the efficiency of therapies with ganciclovir in this cell type and that the anti-CMV effect of cytokines may be different in fibroblasts and in macrophage-like cells.

Abstract
The pathogenesis of dengue hemorrhagic fever (DHF) is not well known, but the role of host factors has been suggested. The level of immunoreactive circulating and cell-generated tumor necrosis factor alpha (TNF alpha) was studied in 35 patients with DHF; its relationship with virus isolation and/or genome detection by reverse transcription polymerase chain reaction (RT-PCR) and specific antibodies were detected by hemagglutination inhibition (HI). Large variation of TNF alpha plasma levels was obtained in dengue-infected patients at the same stage of the disease and at the same day after infection. Most of the patients (14 out of 17 patients) who displayed augmented spontaneous in vitro production of TNF alpha by heparinized whole-blood culture compared with controls also had elevated levels of TNF alpha in the plasma. The TNF alpha values in lipopolysaccharide and phytohemagglutinin heparinized whole-blood cultures were not higher in patients than in controls, but low TNF alpha levels were obtained in three out of 30 patients. An inverse correlation was observed between spontaneous in vitro TNF alpha production and viral replication, which raises the issue of the antiviral effect of TNF alpha in dengue infection. The results do not support the hypothesis of the role of antibody-dependent enhancement giving rise to increased viremic titers and production of TNF alpha in patients. The present study demonstrates the activation of the TNF alpha-producing cells in dengue-infected patients and suggests further investigation to define the mechanism and the role of TNF alpha in the pathogenesis of dengue virus infection.

Abstract
The high number of BCF (10-24%) diseases with its direct link on post-surgical casualties require a very well structured therapy. A study over a period of 17 years on 479 patients, whose age ranged average 37 years, broLen into 52 female et 31 male, shows 83 cases of hydatic livercystis that were aggravated by a BCF. In 23 cases (27.7%) the BCF was large, minimal in 60 cases (72.3%) and for 72% the multivesicular hydatic cystis was altered by a pericystis, often sclerous and calcified. In 9 cases (11%) the main biliary duct was enlarged and showed hydatic remains. 3 patients were under radical treatment (3.6%), 2 (2.45%) underwent a total pericystectomy, and 1 (1.2%) a partial pericystectomy. The 80 other patients went through a saving approach treatment which involved. In 44 cases (55%) a flattening with a simple suture of BCF, in 11 cases (13.75%) a suture combined with an external bile drainage, in 5 cases (6.25%) a suture combined with an epiploic-plastic surgery, in 5 cases (6.25%) the suture was combined with the padding of the residual cavity, in 4 cases (5%) the epiploic plastic surgery was combined with an external bile drainage. In 7 cases (8.75%) a bipolar drainage was used and in 4 cases (5%) there was mobile drainage. For 50% of these patients the post surgical surgery was very simple; the most important aggravations were 12 FBK, 8 subphrenic abscess, 1 choleperitonitis. The average length of stay was 23 days. No death was accounted for. The aim was to assess the different technics proposed in the treatment of BCF and elaborate a therapeutical strategy.

Abstract
Recently it has been reported that cytokine production by T cells in response to antigens may be more sensitive test than lymphoproliferation. T cell reactivities to antigens is usually performed on isolated PBMCs, however whole blood is being used frequently for cytokine production studies. A whole blood assay is described to measure T cell mediated immune responses to HIV-1 and recall antigens. The cultures were performed in 96-well plates in which only 25 microliters of whole blood was required. We studied the production of IFN gamma in short term culture (24 hours) of 1/10 diluted heparinized whole blood (HWB) from 22 HIV-1 (+) patients grouped according to the 1993 classification of the CDC. IFN gamma was measured with an immunoassay in supernatants of HWB cultured in parallel experiments in the presence of supernatant of HIV-1LAI infected CD4+ T cells, p24 HIV antigen, PPD, tetanus toxoid (TET) and PHA. We found no production of IFN gamma in response to HIV-1 antigens in 15 HIV-1 (-) subjects; whereas a specific IFN gamma production in the presence of HIV-1 antigen was obtained in all of the 9 group A patients, in 7 of 8 group B patients and in 2 of 5 group C patients. In response to recall antigens (TET, PPD), we obtained IFN gamma production in 6 of 9 group A patients, 5 of 8 group B patients and in 1 of 5 group C patients, the response to PHA decreased but remained preserved until late in the disease. The HWB assay is a quick and simple potentially valuable tool for assessing cellular immune function in HIV-1+ patients.

Abstract
Monocyte/macrophage cells can be infected with human cytomegalovirus (HCMV) and could be a reservoir and a vehicle for virus spread in infected patients. The monocytic-like cell line THP-1 differentiated along the monocyte pathway with a phorbol ester (phorbol 12-myristate 13-acetate, PMA) for 24h was infected with cell free-supernatant of Towne CMV-strain infected fibroblasts MRC-5. We designed experiments to study the replication of HCMV in PMA treated THP-1 cells, exposed to DHPG (Cymevan, ganciclovir, Syntex). We incubated PMA treated THP-1 cells with DHPG for one to five days at 37 degrees C before or after the infection. The cells were cultivated for 5 days at 37 degrees C then supernatants of culture were collected and they were added to fibroblast cultures. The infection of the fibroblasts was studied on the basis of immune detection of viral immediate early antigens (IEA) in nucleus 24h after culture. Incubation of infected THP-1 cells with 11.1 microM DHPG for 5 days at 37 degrees C resulted in 95 +/- 2% inhibition of the replication whereas incubation of the infected cells with the same concentration of DHPG for two days resulted in 50 +/- 5% inhibition. Pretreatment of cells with DHPG for 5 days induced a 50 +/- 4% decrease of the level of infectious particles produced by HCMV infected cells. This is the first report of the antiviral effect of DHPG in macrophagic-like cells.

Abstract
Monocyte/macrophage cell types can be infected with Human Cytomegalovirus (HCMV) could be a reservoir and a vehicle for virus spread in infected patients. We developed a model to study the effects of antiviral molecules on these cells. The monocytic-like cell line THP-1 and the human diploïd cells MRC-5 were used. THP-1 cells were cultivated with a phorbol 12-myristate 13-acetate (PMA) for 24h prior to the infection. We studied infection of these cells with reference strain (AD-169). A cell free virus suspension of HCMV was preincubated with hyperimmune polyvalent immunoglobulins. The infection of the cells was studied on the basis of immune detection of viral immediate early antigens (IEA) in nucleus 24h after culture. Our results showed that hyperimmune polyvalent immunoglobulins have been able to neutralize fibroblasts and THP-1 cells infection, whereas control antibodies did not inhibit the infection of the cells. This is the first report of the use of monocytic-like cells for testing the efficiency of anti-CMV molecules.
