Abstract
Bone sialoprotein (BSP) is an extracellular matrix (ECM) protein associated with mineralized tissues, particularly bone and cementum. BSP includes functional domains implicated in collagen binding, hydroxyapatite nucleation, and cell signaling, although its function(s) in osteoblast and osteoclast differentiation and function remain incompletely understood. Genetic ablation of BSP in Ibsp knockout (Ibsp-/-) mice results in developmental bone mineralization and remodeling defects, with alveolar bone more severely affected than the femurs and tibias of the postcranial skeleton. The role of BSP in alveolar bone healing has not been studied. We hypothesized that BSP ablation would cause defective alveolar bone healing. We employed a maxillary first molar extraction socket healing model in 42-d postnatalIbsp-/- and wild-type (WT) control mice. Tissues were collected at 0, 7, 14, 21, and 56 d postprocedure (dpp) for analysis by micro-computed tomography (microCT), histology, in situ hybridization (ISH), immunohistochemistry (IHC), and quantitative polymerase chain reaction (qPCR) array. As expected, alveolar bone healing progressed in WT mice with increasing bone volume fraction (BV/TV), bone mineral density (BMD), and tissue mineral density (TMD), transitioning from woven to mature bone from 7 to 56 dpp. Ibsp messenger RNA (mRNA) and BSP protein were strongly expressed during alveolar bone healing in parallel with other osteogenic markers. Compared to WT, Ibsp-/- mice exhibited 50% to 70% reduced BV/TV and BMD at all time points, 7% reduced TMD at 21 dpp, abnormally increased Col1a1 and Alpl mRNA expression, and persistent presence of woven bone and increased bone marrow in healing sockets. qPCR revealed substantially dysregulated gene expression in alveolar bone of Ibsp-/- versus WT mice, with significantly disrupted expression of 45% of tested genes in functional groups, including markers for osteoblasts, osteoclasts, mineralization, ECM, cell signaling, and inflammation. We conclude that BSP is a critical and nonredundant factor for alveolar bone healing, and its absence disrupts multiple major pathways involved in appropriate healing.

Abstract
BACKGROUND Anemia is an important comorbidity in heart failure (HF), and it is associated with increased adverse disease experience and mortality. Previous reports have focused mainly on HF presenting in healthcare settings. We, therefore, set out to establish the nationwide prevalence and temporal trends of anemia in community-based patients with HF in the US. AIM To establish the nationwide prevalence and temporal trends of anemia in community-based patients with HF in the US. DESIGN The NHANES dataset, conducted by the CDC National Center for Health Statistics was used to collect nationally representative data on the health and nutritional status of the non-institutionalized US population. METHODS We utilized the National Health and Nutrition Examination data collected over five survey cycles (2007-16). Included were participants aged 20-80 years with self-reported diagnosis of HF. Anemia was defined using 2 sex specific cut offs of 13 and 12 g/dl (cutoff 1), and 12 and 11 g/dl (cutoff 2), for men and women, respectively. The Chi square test was used to compare prevalence across different categories and survey cycles. Data analysis was done using STATA 16 with P-values < 0.05 considered statistically significant. RESULTS The median hemoglobin in all HF patients was 13.5 g/dl (IQR 12.4-14.5). The prevalence of anemia among community-based patients with HF in the US was 21.34% (cutoff 1) and 9.03% (cutoff 2) and has been stable from 2007 to 2016. The burden of anemia was disproportionately higher in NH Blacks (34.48%, 95% CI 27.12-42.67) and those with BMI < 25 Kg/m2 (17.4%, 95% CI 10.9-26.64). CONCLUSION The prevalence of anemia in patients with HF in the US is at least 9% and has remained stable over the past decade. This high persistent burden with limited proven interventions should spur further efforts aimed at identifying impactful ways of addressing anemia in patients with HF.

Abstract
ALPL encodes tissue-nonspecific alkaline phosphatase (TNAP), an enzyme expressed in bone, teeth, liver, and kidney. ALPL loss-of-function mutations cause hypophosphatasia (HPP), an inborn error-of-metabolism that produces skeletal and dental mineralization defects. Case reports describe widely varying dental phenotypes, making it unclear how HPP comparatively affects the three unique dental mineralized tissues: enamel, dentin, and cementum. We hypothesized that HPP affected all dental mineralized tissues and aimed to establish quantitative measurements of dental tissues in a subject with HPP. The female proband was diagnosed with HPP during childhood based on reduced alkaline phosphatase activity (ALP), mild rachitic skeletal effects, and premature primary tooth loss. The diagnosis was subsequently confirmed genetically by the presence of compound heterozygous ALPL mutations (exon 5: c.346G>A, p.A116T; exon 10: c.1077C>G, p.I359M). Dental defects in 8 prematurely exfoliated primary teeth were analyzed by high resolution micro-computed tomography (micro-CT) and histology. Similarities to the Alpl-/- mouse model of HPP were identified by additional analyses of murine dentoalveolar tissues. Primary teeth from the proband exhibited substantial remaining root structure compared to healthy control teeth. Enamel and dentin densities were not adversely affected in HPP vs. control teeth. However, analysis of discrete dentin regions revealed an approximate 10% reduction in the density of outer mantle dentin of HPP vs. control teeth. All 4 incisors and the molar lacked acellular cementum by micro-CT and histology, but surprisingly, 2 of 3 prematurely exfoliated canines exhibited apparently normal acellular cementum. Based on dentin findings in the proband's teeth, we examined dentoalveolar tissues in a mouse model of HPP, revealing that the delayed initiation of mineralization in the incisor mantle dentin was associated with a broader lack of circumpulpal dentin mineralization. This study describes a quantitative approach to measure effects of HPP on dental tissues. This approach has uncovered a previously unrecognized novel mantle dentin defect in HPP, as well as a surprising and variable cementum phenotype within the teeth from the same HPP subject.

Abstract
Angiomyofibroblastoma (AMF) is a rare benign mesenchymal tumor with tendency to arise in the lower genital tract of middleaged women, predominately in the vulva. A few cases of AMF in males have been reported involving the scrotum, perineum or spermatic cord. We report a new case of AMF arising in the right inguinal region of a 27-year-old man. The tumor was well-circumscribed, myxoid and measured 30 mm in maximum dimension. On microscopic examination, the tumor was composed of spindle cells without atypia and with less than one mitosis figure per 10 high-power fields. Multinucleated cells and mast cells were observed. The stroma was myxoid and edematous with abundant capillary-sized blood vessels. Immunohistochemical staining showed a strong immunoreactivity for desmin and smooth muscle actin. The tumor cells were negative for estrogen receptors and focally positive for progesterone receptors with a low proliferative index of Ki67 (< 5%). This unusual neoplasm should be distinguished from aggressive angiomyxoma and other myxoid malignant tumors.

Abstract
Herein, we highlight the diagnostic challenges of cystic pancreatic tumours, and report a case of chronic pancreatitis caused by a cystic tumour, which consisted in a canal dilatation--and not a pseudocyst. The case thus demonstrates a rare association between a cystic form of chronic pancreatitis and adrenal adenoma. We report the case of a 46-year-old patient with no particular past medical history who presented with long lasting symptoms consisting in an abdominal pain and deterioration in general health. Imaging findings (ultrasound, CT-scan, MRI) showed a 3-cm cystic lesion of the tail of the pancreas associated with a 3-cm adrenal mass. Because of the suspicion of a malignant disease, surgical treatment was performed. Pathological findings consisted in fibrotic chronic pancreatitis with canal dilatation and an adrenal adenoma. Pancreatic cystic lesions are rare tumours. Despite of the multiplicity of imaging techniques, differential techniques lack sensitivity and specificity. Final diagnosis must be based on pathological features.

Abstract
Nasopharyngeal carcinomas (NPC) are a significant problem of public health in Tunisia. They are particular because of their characteristic geographic distribution. The aims of this study were, first, to appreciate the presence of Epstein-Barr virus (EBV) genome by immunohistochemistry (IHC) and in situ hybridization (ISH) and to compare their benefits to NPC diagnosis and, secondly, to verify the relation between NPC and factors bound to the food and environment conditions. Biopsies, recruited at the department of pathology of EPS Charles Nicolle at Tunis, were analyzed for EBV genome presence by ISH of EBV-encoded small RNA1 (EBER1). IHC was done with encoded nuclear antigen (EBNA1), latent membrane proteins (LMP1), and antigen BZ1 anti-Z EBV-replication activator (ZEBRA). An epidemiological study based upon the analysis of a detailed questionnaire submitted to patients (all from the north of Tunisia) and 60 witnesses was done. The statistic analysis was realised by SPSS Windows 11.5 Advanced Statistics. All samples were classified as Undifferentiated Carcinoma of Nasopharyngeal type (UCNT). We found a sex ratio of 2 with a bimodal repartition. ISH showed 96.6% positive samples. IHC revealed the EBV in 90% of cases and 66.7%, respectively, with EBNA1 and LMP1. The statistic analysis showed a meaningful relation (P<0.05, OR>3) between NPC and dietary factors (spices and piquant condiment), alcohol and the water quality.

Abstract
The authors report the case of a 40-year-old woman, who was operated for an ovarian mucinous cystadenocarcinoma. The pathologic findings of the hysterectomy specimen with bilateral salpingoophorectomy showed an ovarian mucinous cystadenocarcinoma associated with an endometrioid adenocarcinoma of the uterine cervix. The mucinous cystadenocarcinoma represents the third most common type of ovarian carcinoma. In the literature, this tumor had been found in association with endocervical adenocarcinoma or with minimal deviation adenocarcinoma (adenoma malignum) of the uterine cervix. However, its association with an endometrioid adenocarcinoma, to our knowledge, has not been reported.

Abstract
Central chondrosarcoma of the tibia is exceptional, particularly in young patients. Low-grade tumors raise difficult problems for histological distinction with enchondroma. We report a case of grade 1 chondrosarcoma located in the upper portion of the tibia in a 17-year-old girl. After radical surgery, outcome was favorable with no recurrence or metastasis at three years follow-up. The distinction between low-grade central chondrosarcoma and enchondroma is one of the most difficult challenges in bone pathology. Clinical, radiographic and pathological data must be considered together to reach certain diagnosis.

Abstract
Hairy cell leukemia is a rare lymphoproliferative disorder which affect predominantly older males. Typical presentation includes pancytopenia, splenomegaly, presence of malignant cells with hairy projections, and some difficulty to perform a bone marrow aspiration. Reported is a 78 year - old female patient, who presented only neutropenia. There was no splenomegaly and the bone marrow aspiration was easy. Diagnosis was based on the presence of characteristic cells in a second bone marrow aspiration, whereas a treatment by recombinant human G-CSF was introduced for a suspicion of an idiopathic neutropenia. Confirmation was done with immunostaining by DBA 44 monoclonal antibody. This is the first case of hairy cell leukemia reported in Dakar, and with an uncommon clinical presentation making it difficult to be recognized.

Abstract
The authors report an unusual case of extensive placental micrometastases of breast carcinoma occurring in a 43 years-old woman, seen at 31 weeks gestation with metastatic disease. A female infant was delivered by caesarean section. Physical examination of the newborn was normal. The mother rapidly died of metastatic disease. Placental metastases from maternal tumours are rarely reported in the literature. The diagnosis is made by histologic examination. Placental metastases are associated with bad prognosis for the mother. The foetus is usually free of tumours when the metastases are limited to the intervillous space.

Abstract
The authors report a new case of mesenchymal chondrosarcoma (MCS), occurring in the upper jaw bone of a 19 year-old woman. Radiographic picture in the bone shows an aggressive osteolytic tumor suspect of malignancy. An incisional biopsy was practiced and the histologic examination has confirmed the diagnosis of MCS. Treatment have consisted of a large resection of maxilla with additional irradiation therapy. The postoperative course was marked by recurrence of the lesion one year later.

Abstract
The peripheral blood lymphocytes of nine patients with hyper immunoglobulin (Ig)M immunodeficiency were studied in an attempt to define the cellular basis of this disorder. B cells were normal in number but qualitatively abnormal in all patients. Approximately one-half of the B cell consisted of small lymphocytes (7-9 mum in diameter) bearing surface IgM and IgD, as well as C3 receptors. These cells were driven to secrete IgM but not IgG after in vitro stimulation by pokeweed mitogen. In the blood there were also large lymphocytes (10-14 mum in diameter) that possessed surface as well as intracytoplasmic IgM but lacked C3 receptors. These cells spontaneously secreted large amounts of IgM in vitro and on electron microscopy were found to be rich in rough endoplasmic reticulum. Such a subpopulation of lymphoid cells was not detected in normal peripheral blood and was unique for all patients with hyper IgM immunodeficiency studied.T cells from all patients were normal in number and in function both in vivo and in vitro and were able to generate adequate T-cell help to support IgG synthesis by normal B cells. No evidence was obtained for T cells capable of suppressing normal IgG synthesis in any of the patients after coculture with normal peripheral blood lymphocytes. The defect in hyper IgM immunodeficiency is intrinsic to B cells, which fail to switch from IgM to IgG synthesis.

Abstract
The pharmacokinetic disposition of prednisolone was studied following oral administration (10 mg) to eight patients with untreated coeliac disease of mild or moderate severity, seven coeliac patients on a strict gluten-free diet and ten normal subjects. No significant differences were shown in the peak prednisolone level, the time of the peak level, the area under the concentration versus time plot, the plasma half-life and the 24 h urinary recovery of prednisolone in the three subject groups. There was however considerable variability within each group. It is concluded that the presence of coeliac disease does not significantly alter the absorption or elimination of prednisolone.

Abstract
The half lives of acetanilide and isoniazid ("model" substrates for oxidation and acetylation respectively) were measured in populations of young (aged 20-35 years) and elderly (aged over 65 years) people. Whereas acetanilide half lives were significantly longer in the elderly, isoniazid half lives were distributed similarly in both populations. The results suggest that liver function does not decline uniformly with age and that heterozygotes for acetylation do not possess survival advantages during their middle years of life.
