Abstract
INTRODUCTION The pneumatic tube system (PTS) is an automated and fast modality of transportation of biological samples, but it has been reported to induce preanalytical errors. AIM To study the influence of transportation by PTS on biochemistry tests which are particularly sensitive to haemolysis and atmospheric pressure variation. MATERIALS AND METHODS We compared laboratory results of arterial blood gas, sodium, potassium, chloride, lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, glucose and haemolysis index of samples conveyed simultaneously by PTS and by courier. RESULTS We recruited 30 patients from the sampling room and 40 patients from the intensive care unit. Transport through PTS resulted in a significant increase in aspartate aminotransferase and potassium without exceeding the limits of acceptability. Potassium was significantly more increased for samples transported in a higher speed line (p = .048) but without exceeding the limits of acceptability. No significant impact was noted on haemolysis indices. The pO2 variations due to PTS transportation exceeded the limit of acceptability with significant intra-individual variations. CONCLUSION Our PTS is validated for biochemistry tests results. It reduces turnaround times without affecting sample quality. However, the interpretation of arterial blood gas results should be careful for samples transported by PTS.

Abstract
BACKGROUND Polycystic Ovary Syndrome (PCOS) is the most frequent endocrine disorder that affects reproductive-age women with important long-term health implications. As such, the anti-Müllerian hormone (AMH) was proposed as a helpful test to identify women with PCOS. The aim of this study was to determine an AMH cut-off value for the diagnosis of PCOS. METHODS This was a two-year cross-sectional study including women of reproductive age, diagnosed with PCOS according to Rotterdam criteria (2003). The control group of healthy women was age-matched. AMH was performed using an electrochemiluminescence immunoassay. AMH levels were compared and evaluated with the receiver operating characteristic curve analysis. RESULTS A total of 130 women were enrolled in this study. Of these, 65 were diagnosed with PCOS, and 65 were healthy. No significant difference was detected in body mass index between the two groups. AMH levels were significantly higher in women with PCOS (p = < 0.001). No significant difference in AMH levels was detected between PCOS phenotypes. A cut-off of 25.1 pmol/L (3.5 ng/mL) could discriminate women with PCOS from controls with a sensitivity of 74% and specificity of 72.3%. The area under the curve was 0.811 (95% CI: 0.73-0.88). CONCLUSIONS Our study suggests that AMH had good diagnostic potential as a complement to Rotterdam criteria for PCOS diagnosis in reproductive-age women of Tunisian origin.

Abstract
Phytoestrogens, with a wide range of beneficial effects, prevent bone loss caused by oestrogen deficiency.The purpose of this study was to evaluate the effect of Medicago sativa ethanol extract compared to 17β-oestradiol on osteoporosis in ovariectomized mice.The study was carried out on female mice, divided into five groups: control mice (GI), Medicago sativa treated mice (0.75 g/kg BW/day) (GII), ovariectomized mice (GIII) and ovariectomized mice treated either with Medicago sativa (GIV) or with 17β-oestradiol (50 µg/Kg BW/day) (GV).Our results showed that Medicago sativa or 17β-oestradiol treatments significantly attenuated perturbations of mineral levels, histological changes and oxidative stress in the femurs of ovariectomized mice.Medicago sativa prevented bone loss induced by oestrogen deficiency, which could be attributed to its richness in kaempferol, syringic acid, naringenin and myrictin. Its effects were more beneficial or similar compared to 17β-oestradiol.

Abstract
The current investigation was carried out to estimate the protective effect of aqueous extract of Cheatomorpha gracilis (AEC) against High fat Diet (HFD) induced liver damage in mice. The results of the in vitro study showed that AEC have higher antioxidant capacities in the DPPH and hydroxyl radical-scavenging assays. Indeed, many phenolic compounds (gallic acid, quercetin, naringenin, apigenin, kaempferol and rutin) were identified in the AEC. In the animal studies, during 6 weeks, HFD promoted oxidative stress with a rise level of malonaldehyde (MDA), protein carbonyls (PCOs) levels and a significant decrease of the antioxidant enzyme activities such as superoxide dismutase, catalase and glutathione peroxidase. Interestingly, the treatment with AEC (250 mg/kg body weight) significantly reduced the effects of HFD disorders on some plasmatic liver biomarkers (AST, ALT and ALP) in addition to, plasmatic proteins inflammatory biomarkers (α2 and β1 decreases / β2 and γ globulins increases). It can be suggest that supplementation of MECG displays high potential to quench free radicals and attenuates high fat diet promoted liver oxidative stress and related disturbances.

Abstract
The current study was carried out to estimate the protective effect of methanolic extract of Chaetomorpha gracilis (MECG) against High Cholesterol Diet (HCD) induced erythrocyte damage in mice. The results of the in vitro assay showed that MECG have higher antioxidant capacities in the DPPH, TAC, ABTS, NBT, NO. inhibition assays. The HPLC analysis confirmed that this potential antioxidant seems to be due to the active compounds, in particular polyphenols, flavonoids. HCD promoted oxidative stress with a rise the level of malonaldehyde (MDA), advanced oxidation protein product (AOPP) levels and a significant decrease of the Vitamin C content, as well the antioxidant enzyme activities such as superoxide dismutase and glutathione peroxidase. In addition, HCD treatment caused significant lipid profile disorders via increase the cholesterol, triglycerides and LDL levels and reduction HDL-Ch level. A statistically significant decrease of Mg2+ and Ca2+ ATPase activities accompanied with a severe damage in the erythrocytes structure and hematological parameters alterations were also noted in hypercholesterolemic mice. Pre-treatment with MECG significantly restored biochemical markers and pathological lesions. It can be suggest that supplementation of MECG displays high potential to quench free radicals and attenuates high cholesterol diet induced erythrocytes oxidative stress and related damages.

Abstract
Aim An association between serum vitamin D (Vit D) levels and systemic lupus erythematosus (SLE) has been reported by several studies that suggested the involvement of genetically determined characteristics of enzymes of vitamin D metabolism. Our study aimed to evaluate the relationship between 25 hydroxyvitamin D (25[OH]D) level, the most representative metabolite of VitD status, and polymorphism of the cytochrome P450, CYP27B1 gene, which influence vitamin D metabolism, and serum levels, in SLE Tunisian patients. Material and Methods A cross‐sectional study has been conducted in SLE patients (supplemented and not supplemented patients), matched to healthy controls by age and gender. The 25[OH]D serum level was measured by chemiluminescence assay and CYP27B1‐1260 genetic polymorphism was carried out using PCR‐RFLP methods. Statistical analysis was made using Shesis and SPSS.20 Software. Results Controls and Vit D not supplemented patients’ groups presented the highest percentage of hypovitaminosis D. A significant difference in the mean level of circulating 25[OH]D between Vit D supplemented SLE patients and controls was observed (23.91 ng/ml and 7.18 ng/ml, respectively p = 3.4 105). Our results showed a correlation of high 25[OH]D level with complement component 3 levels and prednisolone drug. Moreover, the analysis of CYP27B1‐1260 polymorphism in SLE patients and controls revealed a nonsignificant allelic or genotypic association. Conclusion Despite the sunny climate, the high prevalence of Vit D deficiency is common in Tunisia. This hypovitaminosis D feature may affect the Vit D levels in our SLE patients but a direct association with the disease or with the genetically determined features remains unclear. More studies are needed to establish thresholds and susceptibility genes according to the characteristics of each population.

Abstract
BACKGROUND AND AIM The aim of this study is to evaluate the clinical, biological and hematological profiles of autoimmune hemolytic anemia (AIHA) in children and to specify its etiologies, therapeutic modalities, and treatment responses. METHODS This is a 14-year retrospective study of AIHA cases collected at the department of pediatric emergency and reanimation of Hedi Chaker University Hospital in Sfax. We included patients under 14 years old with clinical and biological features of hemolysis and a positive direct antiglobulin test (DAT). The selected patients' demographic characteristics, physical signs, laboratory findings, and treatment responses were recorded. RESULTS Thirteen cases of AIHA were collected, including 8 girls and 5 boys. The median age at diagnosis was 4 years and 6 months (range: 8 months to 13 years). Consanguinity was reported in 6 cases and 4 patients had a previous infection history. The onset of AIHA was progressive in 9 cases, marked by an anemic syndrome and hemolysis symptoms in 6 and 8 cases, respectively. The clinical triad (pallor, jaundice and splenomegaly) was found in only 4 cases. At the time of diagnosis, the median hemoglobin (Hb) level was 6g/dL (range: 4.2 to 9.2g/dL), anemia was non-regenerative in 2 patients. Thrombocytopenia and neutropenia were noted in 5 and 1 patient, respectively. Peripheral smear examination showed spherocytosis in 2 cases. All the patients had a positive DAT. Of these, 10 were positive with IgG and 3 with both IgG and C3d. AIHA was secondary to other conditions in 9 patients: infection (3 cases), autoimmune disease (4 cases), and immunodeficiency (2 cases). All the patients received first-line corticosteroid therapy but only 8 of them required blood transfusions due to severe anemia. Complete remission was obtained in 7 cases. Corticosteroid resistance and dependence were noted in 1 and 2 cases, respectively. During evolution, additional therapy was indicated in 4 patients and it included cyclosporine A, azathioprine, and mycophenolate mofetil (MMF). After a median follow-up of 4.5 years, the cure rate was 80% and only 1 patient (a boy) died due to his underlying pathology. CONCLUSION Our study highlights the rarity, severity, and heterogeneity of etiological contexts of AIHA in children. The therapeutic difficulties justify specific expertise in pediatric hematology.

Abstract
OBJECTIVES Bipolar disorder (BD) etiopathogenesis is still not well elucidated. It has recently been proven that 25-hydroxy vitamin D (25OHD) has an anti-inflammatory and neuroprotective role. Our objectives were to measure 25OHD plasma levels in patients with BD in acute decompensation and compare them with patients with schizophrenia (SCZ) or schizoaffective disorder (SAD) and with healthy controls. METHODS This is a cross-sectional case-control study including male inpatients with a decompensation of their disease who were diagnosed with BD, SCZ or SAD according to DSM-5 criterias. The control group was constituted by unrelated healthy subjects, age-and-sex matched. RESULTS The 25OHD level was significantly higher only in patients with BD compared to controls. 25OHD was also positively correlated to the PANSS scale (r = 0.282, p < 0.001) and to different MOCA scores (r = 0.326, p = 0.006) as well as aspects related to abstraction, attention and memory capacity. Multivariate analysis found that BD acute decompensation was independently related to the rise in plasma 25OHD (p = 0.012; OR =1.157, [1.032 -1.297]). CONCLUSION Our study shows that BD acute decompensation is associated with the rise in plasma 25OHD synthesis. However, the vitamin D dosage relevance as a biomarker of this disease warrants a verification in other studies.

Abstract
BACKGROUND The aim of the present study was to examine the effects of mental training on muscular force generation, hormonal alterations, and physiological adaptations in male trained kickboxers. METHODS Fifty-three male trained kickboxers (24.2±4.4 years, 1.75±0.08 m and 70.4±10.2 kg) were randomly assigned to a physical-training group (PG; N.=20), physical and mental training group (PMG: N.=18, mental-training package [MTP] plus physical training] or control group (CG: N.=15). Physical fitness tests: countermovement jump (CMJ), medicine ball throw (MBT), bench press, and half-squat tests; hormones: resting cortisol (C) blood sample, plasma testosterone (T) concentration, and T/C ratio; and physiological variables: resting heart rate (HR), and blood pressure (BP) were assessed before training commenced (baseline) and at week 6 and 12 of training. RESULTS PMG and PG improved performance in CMJ height (16.2%, 8.4%), MBT (27.9%, 14.2%), bench press (26.5%, 15.7%), half-squat (27.2%, 16.3%), T concentration (35.2%, 22.4%), and T/C ratio (60%, 0%, for PMG only), respectively. In contrast, the C concentration decreased for the PMG (16.3%) and increased for the PG (22%) after 12 weeks. The PMG and PG had significant decrease from pre- to post-training for the resting HR (9.1%, 3%, respectively) and BP (8.5%, 5.3%, respectively). Furthermore, there was a significant increase in MBT (9.3%) after 6 weeks in PMG. Outlined improvements (PMG and PG) were favorable compared to CG (P<0.05) in all instances. CONCLUSIONS The greater muscular force generation in PMG than PG seem to be explained by the reduction of hormonal and physiological stress after 12 weeks.

Abstract
Measurement of thyrotropin and free thyroxin made using immunoassays are usually needed in clinical endocrinology. Here, we report a case of a patient with type 2 diabetes who presented a weight loss. To eliminate hyperthyroidism, thyroid function tests were performed. Free thyroxin (FT4) was decreased using two automated immunoassays TOSOH AIA 1800 and Roche ELECSYS 2010, with a normal thyrotropin value. Thyroid function tests repeated a month later were normal. The patient's history revealed contact with sheep, which may partly explain the interference. Investigations into the patient's serum were carried out using both the PEG test and dilution test. Interference factors were probably antibodies. Despite progress in immunoassays, we should be aware of interference occurrence since it can lead to false results, unnecessary investigations and incorrect treatment. Thus, simple tests must be carried out as if interference in immunoassays were suspected. Dilutions and PEG tests are generally performed as first line investigations.

Abstract
Leiomyosarcoma of the urinary bladder is an extremely rare disease. In this study, which also includes a review of the literature, a new case of urinary bladder leiomyosarcoma has been reported in a 65-year old male, which was detected during an investigation of total hematuria accompanied by burning upon micturition. The clinical examination was normal, but ultrasonography followed by bladder endoscopy showed the presence of a large bladder tumor. The definitive diagnosis of this type of tumor can only be made after histological and immunohistochemical investigation, and to avoid unnecessary surgery it is essential to first differentiate it from an inflammatory pseudosarcoma. Although in the present study the outcome following total cystoprostatectomy was favorable at 3 months follow-up, in general the prognosis is uncertain due to the potentially invasive character of this type of tumor. Given the limited number of studies on the subject treatment still remains controversial, but is essentially based on surgical excision, possibly with adjuvant chemotherapy.

Abstract
Two cases of retroperitoneal benign schwannoma are described with a review of literature. Are analysed the clinical and anatomopathologic features of this rare tumor and the methods of diagnosis. The treatment is the surgical ablation of the tumor commonly easy and complete. When malignancy is established, adjuvant procedures add little to life expectancy and total surgery is done likely to be effective.
