Background: Vascular invasion is possible with bone-and soft tissue tumors like in the other malignant neoplasms. Anymore, it is possible to search the vascular bundle encasement or invasion by conventional axial sections and reconstructed MPR-3D images (MDCTangiography). It is important to notice the early findings of any invasion. Prompt recognition of the invasion, early operation (stent-graft application or reanastomosis) can reduce morbidity rate significantly. The aim of this study was to report the different findings that can be visualized with three-dimensional (3D) image, virtual angioscopy in the evaluation of the tumor and vessel relationship. Material and Method: Four patients with different tumors were evaluated with CT angioscopy to demonstrate their relationship with vessels. Results: CT angioscopy images were demonstrative with adequate quality and did not show occlusion of a major vessel. However displacement of vessel due to compressinn and wall irregularity in apatient was apparent. Conclusion: 3D imaging with virtual angioscopy will be helpful to evaluate the relation of the tumor and vessels. It can lead to surgeons before surgery.

Background: The purpose of this study was to evaluate the effect of intraarticular injections(high and low molecular weight Hyaluronic Acid, NSAID) in patients with mild-to-moderate knee osteoarthritis. Patients and Methods: One hundred twenty patients (34 men, 86 women; mean age 56.55 years; range 40 to 78 years) who were primary knee osteoarthritis of Kellgren-Lawrence grade II-III, divided four groups consisting of randomly. High molecular weight hyaluronic acid content was administered intraarticularly to patients in Group–I, Low molecular weight hyaluronic acid content was administered intraarticularly to patients in Group–II, Group-III were administered Tenoxicam intraarticularly and 0.9 % saline were given to the fourth group as a control group. WOMAC Pain Scale values were applied to patients before treatment and after 3. month treatment. Student's t-test was used in statistical analysis of the data. Results: We have found statistically significant difference between the data picked before and after the treatment between administration of high and low moleculer weight hyaluronic acid. Conclusion: Intra-articular HA injections provide additional short-term benefits, but this therapy should be justified by further controlled studies with longer follow-up and larger patient groups.

ABSTRACT Objectives: Hepatitis B virus, hepatitis virus and human immunodeficiency virus are the bloodborne pathogens that healthcare workers (HCW) are mostly occupationally exposed. To be aware of the danger of these pathogens makes HCWs protect themselves. The vaccination and continuous education also help decreasing these potential risks. Method: In this study the screening data about these infections among 528 employees in a new university hospital in Istanbul is presented. Results: It’s been found that approximately half of the HCWs were vaccinated previously. Conclusion: After the screening, the others were started to be vaccinated and the continuous education programmes were established.

We herein describe a case with calvarial Paget’s disease associated with basilar impression and platybasia leading to bulbomedullary junction compression. The patient was presented with the symptoms of increasing deafness, loss of balance, dysphagia, and neck pain spreading to the arms and skull. The diagnosis of basilar impression and detailed measurements of the craniocervical junction could be possible by the use of magnetic resonance imaging. MRI should be the preferred technique in such cases

Gastrointestinal stromal tumors (GISTs) represent rare neoplasms of the gastrointestinal tract. Here we describe a case with GIST and thrombocytosis presenting as an acute abdomen. Our knowledge, the co-existence of GIST and thrombocytosis has not been reported so far. A 66-year old female was admitted to the emergency room with epigastric pain and vomiting over duration of 3 days. Physical examination showed abdominal distension, rebound tenderness, and a palpable RLQ mass. The abdominal exploration showed that a 6x6x6 cm mass was located on small intestine. The mass was completely resected and enteroenterostomy was performed. Specific immunophenotype studies results showed GIST. During the post operative follow up, platelets were above normal levels 400x109/l. Therefore, bone marrow biopsy was performed and hiperplasia in megakaryocytes were found. The current treatment for localized disease is surgical resection. Co-existence of thrombocytosis and GIST has never been reported.

We present a 48-year-old woman who had a failed previous ceramic-on- ceramic total hip arthroplasty performed for early coxartrosis secondary to acetabular dysplasia. She had fracture and protrusion of the ceramic liner through the titanium acetabular shell without any apparent trauma, possibly due to mistakes during the implantation of the ceramic liner into the metal shell at the initial operation. She was revised with allograft, reinforcement ring, all-polyethylene cup and reinforced stainless-steel femoral head. We think that a layer of polyethylene may be used for elimination of liner impingement with screw heads and for stress absorption, particularly at the time of head implantation.
