Abstract
Background Outcome of intermediate risk rectal cancer may be improved by the addition of oxaliplatin during 5-fluoruracil concomitant neoadjuvant chemoradiotherapy. The purpose of this study is to analyze the main clinical results of the ACCORD12 trial (NCT00227747) in rectal cancer after 5 years of follow-up. Patients and methods Inclusion criteria were as follows: rectal adenocarcinoma accessible to digital examination staged T3-T4 Nx M0 (or T2 Nx distal anterior rectum). Two neoadjuvant chemoradiotherapy regimens were randomized: CAP45 (RT 45 Gy + capecitabine) and CAPOX50 (RT 50 Gy + capecitabine and oxaliplatin). Main end point was sterilization of the operative specimen. Acute and late toxicities were prospectively analyzed with dedicated questionnaires. Results Between November 2005 and July 2008, 598 patients were included in the trial. After a median follow-up of 60.2 months, there was no difference between treatment arms in multivariate analysis either for disease-free survival or overall survival (OS) [P = 0.9, hazard ratio (HR)=1.02; 95% confidence interval (CI), 0.76-1.36 and P = 0.3, HR = 0.87; 95% CI, 0.66-1.15, respectively]. There was also no difference of local control in univariate analysis (P = 0.7, HR = 0.92; 95% CI, 0.51-1.66). Late toxicities were acceptable with 1.6% G3 anal incontinence, and <1% G3 diarrhea, G3 rectal bleeding, G3 stenosis, G3-4 pain, G3 urinary incontinence, G3 urinary retention and G3 skeletal toxicity. There was a slight increase of erectile dysfunction over time with a 63% rate of erectile dysfunction at 5 years. There was no significant statistical difference for these toxicities between treatment arms. Conclusions The CAPOX50 regimen did not improve local control, disease-free survival and overall survival in the ACCORD12 trial. Late toxicities did not differ between treatment arms.

Abstract
Bone marrow necrosis is defined by extensive necrosis of the myeloid tissue and bone marrow stroma. Diagnosis is done on characteristic cytological pattern of the bone marrow aspiration and/or biopsy. We report two observations. The first patient, aged 75, has been hospitalized for fever, asthenia and lower back pain. An haematological malignancy was suspected after observation of a few peripheral blood blast cells, but necrosis was found on the bone marrow aspiration and could not lead to further haematological diagnosis. Within next days, the white blood cell count and the number of blasts increased, leading to the diagnosis of acute monoblastic leukaemia. A chemotherapy was started but the patient died 20 days after admission. The second patient, aged 28, has been hospitalized for severe bleeding a few days after the diagnosis of a metastatic gastric tumour. The bone marrow aspiration, made for the evaluation of a thrombocytopenia, showed a massive necrosis. The patient deceased shortly after hospitalization. According to literature, bone marrow necrosis is in most instances secondary to either an haematological malignancy (60%) or to a solid tumour (30%), but only at times observed with a non-malignant disorder. Bone pain, fever, cytopenias and elevated serum lactic dehydrogenase and alkaline phosphatase are frequently reported, but are mostly non specific of the diagnosis in these malignant conditions. Examination of the bone marrow leads to the diagnosis: cells are pycnotic, scarcely recognizable in a background of amorphous extracellular eosinophilic proteinaceous material, and histology shows disappearance of fat spaces with preservation of the bone tissue. Tissue hypoxemia due to microcirculation failure may be the main mechanism leading to the necrosis, whatever the related disorder. Supportive care together with specific therapy of the causal disease must be started promptly. The prognosis depends on the underlying illness and is generally very poor when extensive necrosis is observed.

Abstract
Bacterial infections are responsible for several changes in the cell blood count, which are usually non specific, although some morphological changes of polymorphonuclear neutrophils may be indicative of sepsis. The presence of bacteria on peripheral blood smears is a rare but extreme situation, related in most instances to a fatal prognosis. The presence of both free and intracellular bacteria was observed in the peripheral blood smear of a critically ill patient with a pneumococcal septicaemia which led to a fatal outcome within the next following hours. If the finding of bacteria on the blood smear is a sign of severe sepsis, the literature review shows that less than 10% of septic patients demonstrate bacteria on the blood smear, and routine search for the diagnosis of sepsis is not recommended. Samples taken from infected central venous catheters are another situation of bacteraemia which must be known, but prognosis is usually not fatal if prompt medical care is performed. Some preanalytical conditions are also associated with the presence of bacteria on the peripheral blood smear, but unrelated to infection of the relevant patient.

Abstract
Root hairs are tubular cells resulting from a tip-localized growth in which calcium ions play a key role. Hypaphorine, an indole alkaloid secreted by the fungus Pisolithus microcarpus during the formation of ectomycorrhizae with the host plant Eucalyptus globulus, inhibits root hair tip growth. Hypaphorine-induced inhibition is linked to a transient depolarization of the plasma membrane and a reorganization of the actin and microtubule cytoskeletons. Here we investigated the activity of hypaphorine on calcium distribution in E. globulus root hairs with the ratiometric fluorochrome calcium indicator Indo-1. In 85% of actively growing root hairs, a significant but modest calcium gradient between the apex and the base was observed due to an elevated cytoplasmic calcium concentration at the apical tip. Following exposure to 1 mM hypaphorine, the apical and basal cytoplasmic Ca(2+) concentration increased in 70 and 77% of the hairs, respectively, 10 min after treatment. This led to a reduced calcium gradient in 81% of the cells. The hypothetical links between calcium concentration elevation, regulation of actin cytoskeleton dynamics, and root hair growth inhibition in response to hypaphorine treatment are discussed.

Abstract
The WHO classification describes a group of myelodysplastic/myeloproliferative diseases, including a provisional entity, refractory anaemia with ringed sideroblasts (RARS) associated with marked thrombocytosis, underlining that is a provisional entity without consensus of belonging to myelodysplastic rather than to myeloproliferative syndromes. The authors report two cases with features of refractory anaemia with excess of ringed sideroblasts and marked thrombocytosis. In the first case, RARS is concomitant with thrombocytosis and fits the WHO criteria for this temporary entity. The second case is a typical RARS, who developed a thrombocytosis after several years and emphasizes that a link, at least progressive, exists between RARS and myeloproliferative disorders. The authors summed up the various situations related to secondary or primary acquired sideroblastic anaemia, likewise to primitive and reactive thrombocytosis. The cases of RARS + marked thrombocytosis reported in the literature are few in number and do not allow to settle between a particular form of myelodysplastic syndrome and a myeloproliferative disorder, a fully justified reason to classify these patients in a temporary group. To date, there is no codified therapy for this disorders.

Abstract
Maturity-onset diabetes of the young (MODY) is a monogenic subtype of diabetes mellitus characterized by a young onset of type 2 diabetes, some abnormalities of the beta-cell function and an autosomal dominant inheritance with high penetrance. MODY types represent less than 5% of all cases of type 2 diabetes. Six genetic mutations have been described, one of them affecting the glucokinase gene (MODY 2) and the others various transcription factors HNF-1alpha, HNF-4alpha, HNF-1beta, IPF-1 and NeuroD (MODY 1,3,4,5,6, respectively). These different underlying gene mutations are associated with different clinical forms of the disease. Among the two most frequent forms, MODY 2 (mutation of the glucokinase gene) has a benign clinical evolution whereas MODY 3 (mutation of HNF-1alpha gene) has a much more severe evolution. The recognition of the MODY diabetes is important in clinical practice and may lead to the discovery of new more specific molecular therapeutic targets.

Abstract
Ghrelin is a peptide hormone secreted by the stomach. It was initially described as a stimulant of growth hormone secretion. Soon, however, it was discovered to play an important role in feeding behaviour in animals and in appetite regulation in man: ghrelin stimulates appetite, and as such is an orexigenic peptide implicated in energy balance mechanisms and weight gain. Abnormal ghrelin activity leads to over- or underweight. Additionally, the efficacy of different treatment strategies against obesity seems to be related to modifications in plasma ghrelin levels. This review summarizes the current knowledge about ghrelin and its implications in obesity medicine.

Abstract
The aim of this prospective, monocentric, opened study and with random order for antihypertensive sequence was to compare a betablocker with sympathomimetic activity (ACE) and an alphabetablocker (LAB) to the gold standard treatment (MD) in moderate HDP (BP greater than 90 mmHg). This study (January 1984 to December 1985) includes 63 women, mean age 28.2 years, divided into three comparable subgroups (age, parity, risk factors and initial level of SBP/DBP). Initial doses are 500 mg/bid (MD), and 400 mg/bid (ACE, LAB) and optimal dosages could not be respectively more than 1500 mg/bid (MD) or 1200 mg/bid (ACE, LAB). Usual criteria for maternal and foetal care are taken into account. The chi 2 test, the Student "t" test and the Kruskall Wallis test were used for statistical analysis. The results show: 1--A similar antihypertensive effect for MD and LAB, but significantly less for ACE (initial PAD-37th week PAD: MD +/- 18.8 +/- 2; LAB = -17.9 +/- 3; ACE = - 8.2 +/- 2.7 mmHg, p less than 0.02; 2--A more frequent adjustment of daily dosage with MD (n = 15) than with ACE (n = 10) or LAB (n = 7); 3--The absence of any significant difference for uricemia level, platelet counts, foetal cardiac rythm, and occurrence of pre-eclampsia (MD = 4; ACE = 3; LAB = 4; 4--An equivalent birth-weight (MD = 3110 +/- 628 g; ACE = 3115 +/- 645.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The results of the treatment in hypertension with pregnancy by a alpha-beta blocker in 58 women show: the good tolerance of the drug and its lack of teratogenic effect, its quasi-constant efficiency (91%) in hypertension, its benefit repercussion on neonatal weight. However, this therapeutics requires a maternal careful watching all along pregnancy, and especially of the new-born children, with regard to the risk of hypoglycemia.

Abstract
This study investigates the effect of Acarbose, a complex oligosaccharide of microbial origin with glucosidase-inhibiting properties in alimentary hypoglycemia secondary to rapid gastric emptying and in reactive hypoglycemia either isolated or associated with impaired glucose tolerance. Twenty-four patients complaining of symptoms suggesting hypoglycemia which occurred after meals and who showed blood glucose values of 2.5 mmol/l (45 mg/dl) or below on one or more occasions during a 5-h oral glucose tolerance test were selected and divided into three groups. Group I comprized seven patients with demonstrated rapid gastric emptying; group II comprized eight patients with impaired glucose tolerance, whereas the nine patients of group III were considered to present with "isolated reactive hypoglycemia" since they had a normal glucose tolerance and did not have either glycosuria or gastroduodenal pathology. All patients were submitted to two oral 75-g sucrose tolerance tests. Acarbose (100 mg) or placebo was ingested with the first drought of the sucrose solution administered in a randomized order. The investigation was performed in a double-blind manner. In all three groups Acarbose significantly reduced the magnitude of post-sucrose reactive hypoglycemia. The blood glucose nadir also occurred later, but this effect was statistically significant in group II only. In patients of groups II and III, such improvement of the glucose nadirs was preceded by a significant reduction of the post-sucrose glycemic peak. In all three groups, the insulin response to oral sucrose was reduced by Acarbose. Another consistent finding was the lack of sucrose-induced glucagon suppression when Acarbose was given. These data suggest that Acarbose might be a useful adjunct to the management of functional hypoglycemia.

Abstract
Acarbose, an alpha-glucosidase inhibitor, delays starch digestion and inhibits intestinal sucrase and maltase activity. Twenty-eight insulin dependent diabetics were given Acarbose (3 x 100 mg daily) over a two month period, preceded and followed by a two month placebo period. Acarbose reduced post-breakfast and post-dinner blood glucose values by 25% (p less than 0.001) and 24% (p less than 0.05) respectively. It also significantly reduced mean daily blood glucose by 18% (p less than 0.05) and mean amplitude of glycaemic excursions from 8.0 +/- 0.6 to 5.5 +/- 0.4 mmol/l (p less than 0.0005). Weight did not change significantly. Daily caloric and carbohydrate intake remained constant throughout the study while insulin requirements decreased slightly but significantly. Out of the 28 patients, 18 had absent while ten had slight residual B cell function as assessed by plasma C-peptide measurements. Treatment with Acarbose did not significantly affect residual B cell function. The beneficial effect of Acarbose on blood glucose control was seen in patients both with and without residual B cell secretion. The major side-effect was flatulence which was never severe enough to interrupt treatment, but led to a 50% reduction of the dose in one patient. It is concluded that Acarbose represents a useful additional means of improving metabolic control in insulin dependent diabetics.

Abstract
The authors collected a series of 31 cases of seminoma of the ovary over a period of 12 years. Statistical data, including the results of of lymphography, indicate that the prognosis is good, the application of strict rules in treatment being an essential condition. Certain patients with a pure seminoma of the ovary (20% of cases) die despite early and appropriate treatment. Such a fatal outcome occurs usually during the first 18 months. The prognosis in such cases may be explained in part by the degree of extension initially but the course in certain patients, fortunately rare, is quite dramatic. This can be explained neither on the basis of the histological type nor any inadequacy in therapy. Some special unknown factor must be involved. In general combined surgery and radiotherapy, adapted to the degree of extension of the disease, give the best change of definitive cure and, for the majority of patients, an entirely normal life from a feminine and maternal standpoint. This possibility of combining cure with conservation remains the basis of treatment of seminoma of the ovary in favourable cases.
