Abstract
The efficacy of wood dust fibre treatment on the property of wood dust reinforced recycled polypropylene composite (r-WoPPC) filament was investigated. The wood dust fibre was treated using alkali, silane, and NaOH-silane. The treated wood fibre was incorporated with r-PP using a twin-screw extruder to produce filament. The silane treatment on wood dust fibre enhances interfacial bonding between wood fibre and recycled PP; hence, a filament has the highest wire pull strength, which is 35.2% higher compared to untreated and alkaline-treated wood dust filament. It is because silanol in silane forms a siloxane bond that acts as a coupling agent that improves interfacial bonding between wood dust fibre and recycled PP. The SEM micrograph of the fracture structure reveals that treated silane has strong interfacial bonding between wood dust fibre and recycled PP, having minimal void, gap, and good fibre adhesion. The water absorption test results indicate that filament with treated wood dust absorbs less water than filament with untreated wood because the treatment minimizes the gap between wood fibres and recycled PP. The FTIR analysis identified the presence of silane on the wood dust surface for silane-treated wood dust. The DSC studies suggest that the temperature range 167-170 °C be used in the extrusion machine to produce r-WoPPC filament. As a result, r-WoPPc filaments containing silane-treated wood dust have better mechanical properties and have a greater potential for usage in FDM applications.

Abstract
Abstract
Introduction/Objective
Plasmablastic myeloma (PBM) is a rare and aggressive plasma cell neoplasm. Differentiating PBM from plasmablastic lymphoma (PBL) represents a diagnostic challenge, as both diseases have overlapping cytomorphologic and immunophenotypic features. Genetic mutations in MYC occur in a majority of PBL cases but rarely in PBM, thus can theoretically be used to differentiate between both neoplasms.
Methods
We report a case of a 53-year-old female who presented with a rapidly growing mass in her right mandible. Biopsy revealed circumscribed nodules of immunoblastic cells with moderate cytoplasm, large vesicular nuclei and large prominent nucleoli. Apoptotic debris and brisk mitoses were present. Molecular testing revealed a C-MYC rearrangement. The location of the neoplasm and the above described morphological features were suggestive of PBL, especially with a positive C-MYC rearrangement. The neoplastic cells were positive for CD138, MUM1,CD56 and kappa; and negative for CD45, CD20, PAX5, CD3, CD5, CD30, EBER-ISH, HHV8, ALK-1, Lambda, EMA, CD21, CD23, pancytokeratin, CK20, CK7, Cam5.2, chromogranin, synaptophysin, HMB45, S100, P16, P40. MIB-1 showed high positivity, approximately 95%.
Results
Patient underwent further diagnostic work up, her HIV antibodies result were negative however, she was found to be anemic (Hemoglobin 6.6 g/dl; reference range 12-16 g/dl) and hypercalcemic (Calcium 12.3 mg/dl; reference range 8.5-10.5 mg/dl). PET scan revealed multiple hypermetabolic lytic bone lesions. The bone marrow biopsy showed 80% cellularity with extensive involvement by atypical plasmacytic cells forming large clusters. The patient’s final diagnosis was PBM.
Conclusion
Differentiating PBM from PBL is essential as treatment is different. Although MYC rearrangement in PBM is not common, it has been demonstrated and therefore should not be used to exclude this diagnosis. Here, we highlight the importance of correlating detailed clinical, radiological, laboratory, histological and genetics data for reaching the final diagnosis.

Abstract
This study assessed the effect of partial replacement of cement with plantain peel ash (PPA) and Polystrene (POL) on the compressive strength of concrete as a means of managing waste. Concrete specimens were prepared with a mix ratio of 1:2:4 (cement: sand: granite) water/cement ratio of 0.6, thereafter cement was partially replaced with PPA, POL and PPA/POL in increasing percentages of 5, 10, 15 and 20% by weight. Physical, chemical and microstructural analyses were also conducted on the aggregates and materials used. Workability of the concrete specimens was observed to improve upon addition of PPA and POL separately but not with blended PPA/POL while compressive strength decreased with addition of the three compounds. The observed results can be attributed to the lack of sufficient cementitious properties in the materials, and hence, the study discourages the use of these materials as they do not significantly improve concrete strength.

Abstract
Extramedullary hematopoiesis, which represents ectopic blood cell production, is usually an incidental finding accompanying hematologic pathology. The liver and spleen are the most common sites of extramedullary hematopoiesis, but thoracic involvement is likewise observed. Pleural effusions in the setting of intrathoracic extramedullary hematopoiesis have been attributed to mechanical interactions between the pleural surface and neighboring paravertebral masses consisting of hematopoietic tissue. Rupture of these highly vascularized lesions into the adjacent pleural space has been the putative mechanism in cases complicated by hemothorax. Histologically proven instances of islets of extramedullary hematopoiesis occurring on the pleural surface itself are exceedingly rare. Our case of a patient with myelofibrosis and massive pleural effusion is only the third such example described in the literature and the second to result in a confirmed hemothorax requiring surgery. As expected, technetium-99m sulfur (Tc-99m sulfur) colloid scanning accurately localized sites of extramedullary hematopoiesis in our patient, and there was a salutary response to radiation therapy.

Abstract
Primary hepatic malignancies are uncommon in pediatrics. Tumors such as hepatocellular carcinoma (HCC) develop typically in the setting of chronic liver disease. The incidence of HCC in Wilson's disease-related cirrhosis is disproportionately lower than in many other forms of end-stage liver disease. A preadolescent girl presented with Wilson's disease cirrhosis and a HCC requiring orthotopic liver transplantation. This case highlights the need to consider hepatic malignancies even in young Wilson's disease patients. Pediatric Wilson's disease and the hepatic tumor literature are reviewed.

Abstract
Glomerular sparing (GS) is defined as a unique growth pattern in which tumor cells replace the majority of renal tubes and overrun intact glomeruli. This phenomenon has been well recognized by pathologists as a typical infiltrative pattern and some studies suggested it was an independent risk factor. Here, we study the clinical, pathological, and immunohistochemical features of primary kidney neoplasms with glomerular sparing pattern. We searched the archives of our pathology department for nephrectomy specimens and reviewed all pathology reports from 2009-2013. We selected cases with tumor and collected clinicopathological information, focusing on re-evaluation of cases with glomerular sparing pattern. To facilitate our study we performed immunohistochemical stains of PAX-8, p63, and InI-1 on selected cases. We selected a total of 204 nephrectomy cases in this study, including 163 cases of renal cell carcinoma; 37 cases of urothelial carcinoma; 4 cases from other categories (Wilms tumor, primary diffuse large B-cell lymphoma, angiolipoma, rhabdoid tumor). Finally, we identified 7 cases of primary kidney tumors with glomerular sparing pattern: 2 cases of clear cell renal cell carcinomas (ccRCC), 1 case of collecting duct carcinoma, 2 cases of urothelial carcinoma (UC), 1 case of diffuse large B-cell lymphoma and 1 case of malignant rhabdoid tumor. The primary kidney tumors with glomerular sparing pattern are rare and incidence in our study is <4% (7/204). There is no specificity for any tumor type, but more commonly seen in high grade UC rather than RCC. It can also be seen in rare neoplasms such as collecting duct carcinoma, lymphoma and malignant rhabdoid tumor. These GS cases need to be recognized as they are often associated with high grade, high stage, large tumor size, and worse prognosis.

Abstract
Introduction: Pericardial synovial sarcoma is an extremely rare tumor with poor prognosis. Timely diagnosis and aggressive multimodal management improves patient outcome. We present our experience of diagnosis and management of a young patient with monophasic synovial sarcoma arising from pericardium. Case: A 27-year-old man presented with dyspnea and cough of three weeks duration. Examination revealed sinus tachycardia, distant heart sounds and elevated jugular venous pressure. Chest X-ray showed widened mediastinum. Transthoracic echocardiogram (TTE) noted large pericardial effusion with tamponade physiology. Therapeutic pericardiocentesis yielded hemorrhagic fluid. Computed tomography (CT) of the chest showed persistent pericardial effusion and a left anterior mediastinal mass. Left anterior thoracotomy, pericardial window and left anterior mediastinotomy were done, revealing a well-encapsulated gelatinous tumor originating from the pericardium. Histology and immunohistochemical profile showed the tumor to be a monophasic synovial sarcoma. Fluorescent in-situ hybridization (FISH) was positive for SS18 (SYT) gene rearrangement on chromosome 18q11, substantiating the diagnosis. Work-up for metastases was negative. Neo-adjuvant chemotherapy with high dose ifosfamide led to substantial reduction in the size of the tumor. The patient underwent surgical resection and external beam radiation therapy (EBRT) post surgery. He had symptom-free survival for 8 months prior to local recurrence. This was managed with left lung upper lobectomy and follow-up chemotherapy with docetaxel. The patient is currently stable with an acceptable functional status. Conclusion: In patients with pericardial effusions of unknown etiology, multiple modalities of cardiac imaging must be employed if there is suspicion of a pericardial mass. CT and magnetic resonance imaging (MRI) are useful to evaluate for pericardial thickening or masses in addition to TTE. Treatment of synovial sarcoma is not well established. Surgery is the cornerstone of treatment. In non-resectable tumors, aggressive neo-adjuvant chemotherapy with ifosfamide followed by surgical resection and EBRT may lead to improved outcome.

Abstract
Nested stromal epithelial tumor is a recently described primary neoplasm of the liver. This tumor is characterized by well-demarcated nests of spindle and epithelioid cells with occasional calcification and bone formation. An association between these tumors and Cushing syndrome has been described. Herein we report a case of a recurrent nested stromal epithelial tumor of the liver in a 17-year-old female with aggressive clinical behavior and an extrahepatic lymph node metastasis. Also, we provide the first detailed clinical, histologic, immunohistochemical, and cytogenetic comparison of the original and recurrent tumors. Initially, the patient presented with Cushingoid symptoms and epigastric pain, radiating to her back. A computed tomographic (CT) scan revealed a large lesion in the liver. After a partial hepatectomy, the Cushingoid features were resolved. A year later, a CT scan revealed multiple lesions within the liver, and positron emission tomographic/CT imaging showed a hypermetabolic lymph node. The patient underwent a cadaveric liver transplant. Histologically, both the original and recurrent tumors had similar characteristics, with different immunoreactivity, correlating with the absence of systemic hormonal symptoms. Electron microscopy of the original neoplasm revealed an abundance of rough cytoplasmic reticulum and mitochondria. No evidence of endocrine differentiation was found. Cytogenetics of the primary tumor was complex with an abnormal hypotriploid karyotype. Our data indicate that patients with nested stromal epithelial tumor of the liver must be carefully followed with imaging to detect hepatic recurrence and extrahepatic metastases.

Abstract
False-positive diagnosis of lymph nodes occurs when a benign element in a lymph node, or in its capsule, is interpreted as metastatic carcinoma. This report describes a patient with breast carcinoma who had megakaryocytes in axillary sentinel lymph nodes mimicking metastatic carcinoma. The patient had no history of a hematologic disease, and we found no evidence of a concurrent hematopoietic disorder. The megakaryocytes were reactive for CD31, CD61, and von Willebrand factor, but not for cytokeratin (AE1/AE3). Megakaryocytes should be added to the list of benign histologic abnormalities that may simulate metastatic carcinoma in a sentinel lymph node.

Abstract
BACKGROUND Malignant rhabdoid tumor of the kidney in children is considered a distinct entity. Malignant tumors with rhabdoid features in adults in extrarenal locations and in children over the age of 5 years are considered phenotypic variants. CASE In a case of recurrent transitional cell carcinoma with rhabdoid features of the kidney in an adult, confirmed immunohistochemically and ultrastructurally, fine needle aspiration cytology showed discohesive, large- to medium-sized polygonal cells with eccentric nuclei; prominent nucleoli; abundant, pink cytoplasm; and paranuclear, eosinophilic density, corresponding to cytoplasmic eosinophilic globules seen in the histologic sections and cytoplasmic filamentous inclusions seen ultrastructurally. CONCLUSION The cytologic features of malignant rhabdoid tumors are characteristic.

Abstract
The effect of supplementing a regular diet with riboflavin or a combination of riboflavin and ascorbic acid on haematological indices was studied in 27 young Nigerian adults. Vitamin supplementation produced a significant increase (p less than 0.001) in haemoglobin concentration, haematocrit level and erythrocyte count. Both males and females responded similarly to the supplementation. The effect of riboflavin was similar to the combined effect of riboflavin and ascorbic acid. A significant association suggestive of enhanced erythropoiesis existed between Hb concentration and erythrocyte count in vitamin-supplemented subjects (r = 0.9722, p less than 0.002). The withdrawal of vitamin(s) supplements significantly diminished Hb concentration, haematocrit level and erythrocyte count to values similar to placebo. The data further showed that, even in malarial infection, Hb concentration, Hct level and erythrocyte count were maintained if high vitamin status was established through supplementation.

Abstract
Free intracellular Mg2+ concentration ([Mg2+]i) was measured in cold-stored human erythrocytes by the method of null-point titration with ionophore A23187. [Mg2+]i was 311 +/- 41 microM (mean +/- S.D.) for cells stored 0-10 days, increasing to 458 +/- 64 microM for cells stored 22-48 days. The values for stored cells were higher than those previously determined by a 31P-NMR method (Bock et al. (1985) Blood 65, 1526-1530); however, the null-point method requires extensive washing of the cells, which we have found to increase NMR-measured [Mg2+]i. The null-point values still represent a small fraction of total cell Mg2+, and confirm that binding of Mg2+ to ligands other than ATP and 2,3-bisphosphoglycerate must increase during storage. As an initial test of whether this may imply suboptimal availability of Mg2+ for cell preservation, we used A23187 to prepare erythrocytes with altered Mg2+ content, then removed ionophore and stored the cells in plasma-free medium for up to 2 weeks. Higher Mg2+ content had a very significant positive correlation (P less than 0.0001) with higher cell ATP concentrations. Storage did not significantly affect basal or Na+-stimulated efflux of Mg2+ from Mg2+-loaded red cells.
