Relationship between Tibial conformation, cage size and advancement achieved in TTA procedure

Previous studies have suggested that there is a theoretical discrepancy between the cage size and the resultant tibial tuberosity advancement, with the cage size consistently providing less tibial tuberosity advancement than predicted. The purpose of this study was to test and quantify this in clinical cases. The hypothesis was that the advancement of the tibial tuberosity as measured by the widening of the proximal tibia at the tibial tuberosity level after a standard TTA, will be less than the cage sized used, with no particular cage size providing a relative smaller or higher under-advancement, and that the conformation of the proximal tibia will have an influence on the amount of advancement achieved

Hypercalcemia and huge splenomegaly presenting in an elderly patient with B-cell non-Hodgkin's lymphoma: a case report

<p>Abstract</p> <p>Introduction</p> <p>Hypercalcemia is the major electrolyte abnormality in patients with malignant tumors. It can be due to localized osteolytic hypercalcemia or elaboration of humoral substances such as parathyroid hormone-related protein from tumoral cells. In hematological malignancies, a third mechanism of uncontrolled synthesis and secretion of 1-25(OH)₂D₃from tumoral cells or neighboring macrophages may contribute to the problem. However, hypercalcemia is quite unusual in patients with B-cell non-Hodgkin's lymphoma.</p> <p>Case presentation</p> <p>An 85-year-old Caucasian woman presented with low grade fever, anorexia, abdominal discomfort and fullness in her left abdomen for the last six months. She was mildly anemic and complained of fatigability. She had huge splenomegaly and was hypercalcemic. After correction of her hypercalcemia, she had a splenectomy. Microscopic evaluation revealed a malignant lymphoma. Her immunohistochemistry was positive for leukocyte common antigen, CD20 and parathyroid hormone-related peptide.</p> <p>Conclusion</p> <p>Immunopositivity for parathyroid hormone-related peptide clearly demonstrates that hypersecretion of a parathyroid hormone-like substance from the tumor had led to hypercalcemia in this case. High serum calcium is seen in only seven to eight percent of patients with B-cell non-Hodgkin's lymphoma, apparently due to different mechanisms. Evaluation of serum parathyroid hormone-related protein and 1-25(OH)₂D₃can be helpful in diagnosis and management. It should be noted that presentation with hypercalcemia has a serious impact on prognosis and survival.</p

Differential parameters of male and female Odontobuthus doriae

Background: With respect to the importance of morphological parameters in zoology and their application to differentiate male from female specimens, the present study was conducted to identify the differential parameters of male and female Odontobuthus doriae. Materials and methods : It was a descriptive study. 91 Odontobuthus doriae that their sex was previously determined according to their fertilization parameters were selected. Having put them in alcohol, the number of ventral serration, length of shoulder, and length of scorpion were determined using a ruler and t-test was used for data analysis. Results : The study population included 39 male and 51 female Odontobuthus doriae. One male Odontobuthus doriae was omitted due to abnormality in its shoulder. The mean number of ventral serratio in each side was 31±3 in male and 22±2 in female Odontobuthus doriae, respectively (p<0.001). The mean length of shoulder was 6.5±1.65 in female and 8±2mm in male Odontobuthus doriae, respectively (p<0.001) and the mean length of male and female Odontobuthus doriae was 5.35±1.65 and 5.35±2.15, respectively (NS). Conclusion : The number of ventral serratio, and length of the shoulder can be used to differentiate male and female Odontobuthus doriae
